text/xml is for documents that would be meaningful to a human if presented as text without further processing, application/xml is for everything else

Every XML entity is suitable for use with the application/xml media type without modification. But this does not exploit the fact that XML can be treated as plain text in many cases. MIME user agents (and web user agents) that do not have explicit support for application/xml will treat it as application/octet-stream, for example, by offering to save it to a file.

To indicate that an XML entity should be treated as plain text by default, use the text/xml media type. This restricts the encoding used in the XML entity to those that are compatible with the requirements for text media types as described in [RFC-2045] and [RFC-2046], e.g., UTF-8, but not UTF-16 (except for HTTP).

I was having a problem getting my ASP.NET 5.0/MVC 6 app to serve static binary file types or browse virtual directories. It looks like this is now done in Configure() at startup. See http://docs.asp.net/en/latest/fundamentals/static-files.html for a quick primer.

Boris Zbarsky (Mozilla), who probably knows more about the innards of Gecko than anyone else, provided at http://lists.w3.org/Archives/Public/public-html/2009Apr/0195.html the pseudocode repeated below to describe what Gecko based browsers do:

if (@type not set or empty) {
   if (@language not set or empty) {
     // Treat as default script language; what this is depends on the
     // content-script-type HTTP header or equivalent META tag
   } else {
     if (@language is one of "javascript", "livescript", "mocha",
                             "javascript1.0", "javascript1.1",
                             "javascript1.2", "javascript1.3",
                             "javascript1.4", "javascript1.5",
                             "javascript1.6", "javascript1.7",
                             "javascript1.8") {
       // Treat as javascript
     } else {
       // Treat as unknown script language; do not execute
     }
   }
} else {
   if (@type is one of "text/javascript", "text/ecmascript",
                       "application/javascript",
                       "application/ecmascript",
                       "application/x-javascript") {
     // Treat as javascript
   } else {
     // Treat as specified (e.g. if pyxpcom is installed and
     // python script is allowed in this context and the type
     // is one that the python runtime claims to handle, use that).
     // If we don't have a runtime for this type, do not execute.
   }
}

Alternatively, if you're working in .NET v4.5 or above, try using System.Web.MimeMapping.GetMimeMapping(yourFileName) to get MIME types. It is much better than hard-coding strings.

My problem is that I was using webpack and in my HTML CSS link I had a relative path, and anytime I would navigate to a nested page, that would resolve to the wrong path:

<link rel="stylesheet" href='./index.css'>

so the simple solution was to remove the . since mine is a single-page application.

Like this:

<link rel="stylesheet" href='/index.css'>

so it always resolves to /index.css

The header just denotes what the content is encoded in. It is not necessarily possible to deduce the type of the content from the content itself, i.e. you can't necessarily just look at the content and know what to do with it. That's what HTTP headers are for, they tell the recipient what kind of content they're (supposedly) dealing with.

Content-type: application/json; charset=utf-8 designates the content to be in JSON format, encoded in the UTF-8 character encoding. Designating the encoding is somewhat redundant for JSON, since the default (only?) encoding for JSON is UTF-8. So in this case the receiving server apparently is happy knowing that it's dealing with JSON and assumes that the encoding is UTF-8 by default, that's why it works with or without the header.

Does this encoding limit the characters that can be in the message body?

No. You can send anything you want in the header and the body. But, if the two don't match, you may get wrong results. If you specify in the header that the content is UTF-8 encoded but you're actually sending Latin1 encoded content, the receiver may produce garbage data, trying to interpret Latin1 encoded data as UTF-8. If of course you specify that you're sending Latin1 encoded data and you're actually doing so, then yes, you're limited to the 256 characters you can encode in Latin1.

You should install IIS sub components from

Control Panel -> Programs and Features -> Turn Windows features on or off

Internet Information Services has subsection World Wide Web Services / Application Development Features

There you must check ASP.NET (.NET Extensibility, ISAPI Extensions, ISAPI Filters will be selected automatically). Double check that specific versions are checked. Under Windows Server 2012 R2, these options are split into 4 & 4.5.

Run from cmd:

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ir

Finally check in IIS manager, that your application uses application pool with .NET framework version v4.0.

Also, look at this answer.

I think the root for this confusion is well explained in this wikipedia article.

While the IANA-registered MIME type for ICO files is image/vnd.microsoft.icon, it was submitted to IANA in 2003 by a third party and is not recognised by Microsoft software, which uses image/x-icon instead.

If even the inventor of the ICO format does not use the official MIME type, I will use image/x-icon, too.

mimetype headers are recognised by the browser for the purpose of a (fast) possible identifying a handler to use the downloaded file as target, for example, PDF would be downloaded and your Adobe Reader program would be executed with the path of the PDF file as an argument,

If your needs are to write a browser extension to handle your downloaded file, through your operation-system, or you simply want to make you project a more 'professional looking' go ahead and select a unique mimetype for you to use, it would make no difference since the operation-system would have no handle to open it with (some browsers has few bundled-plugins, for example new Google Chrome versions has a built-in PDF-reader),

if you want to make sure the file would be downloaded have a look at this answer: https://stackoverflow.com/a/34758866/257319

if you want to make your file type especially organised, it might be worth adding a few letters in the first few bytes of the file, for example, every JPG has this at it's file start:

if you can afford a jump of 4 or 8 bytes it could be very helpful for you in the rest of the way

:)

Do keep in mind that the file.getContentType could also output application/octet-stream instead of the required application/vnd.openxmlformats-officedocument.spreadsheetml.sheet when you try to upload the file that is already open.

one of the other tool (besides file) you can use is xdg-mime

eg xdg-mime query filetype <file>

if you have yum,

yum install xdg-utils.noarch

An example comparison of xdg-mime and file on a Subrip(subtitles) file

$ xdg-mime query filetype subtitles.srt
application/x-subrip

$ file --mime-type subtitles.srt
subtitles.srt: text/plain

in the above file only show it as plain text.

When uploading .mp4 file into Perl script, using CGI.pm I see it as video/mp when printing out Content-type for the uploaded file. I hope it will help someone.

In your apache's httpd.conf, just add such a line:

AddType application/x-javascript .js

It's been a few years, and Chrome at least makes use of this attribute. This attribute is very useful from a usability standpoint as it will filter out the unnecessary files for the user, making their experience smoother. However, the user can still select "all files" from the type (or otherwise bypass the filter), thus you should always validate the file where it is actually used; If you're using it on the server, validate it there before using it. The user can always bypass any client-side scripting.

I use an hybrid solution:

    using System.Runtime.InteropServices;

I couldn't possibly explain it better than wikipedia does: http://en.wikipedia.org/wiki/MIME_type

In addition to e-mail applications, Web browsers also support various MIME types. This enables the browser to display or output files that are not in HTML format.

IOW, it helps the browser (or content consumer, because it may not just be a browser) determine what content they are about to consume; this means a browser may be able to make a decision on the correct plugin to use to display content, or a media player may be able to load up the correct codec or plugin.

Call MimeMessage.saveChanges() on the enclosing message, which will update the headers by cascading down the MIME structure into a call to MimeBodyPart.updateHeaders() on your body part. It's this updateHeaders call that transfers the content type from the DataHandler to the part's MIME Content-Type header.

When you set the content of a MimeBodyPart, JavaMail internally (and not obviously) creates a DataHandler object wrapping the object you passed in. The part's Content-Type header is not updated immediately.

There's no straightforward way to do it in your test program, since you don't have a containing MimeMessage and MimeBodyPart.updateHeaders() isn't public.

Here's a working example that illuminates expected and unexpected outputs:

public class MailTest {

  public static void main( String[] args ) throws Exception {
    Session mailSession = Session.getInstance( new Properties() );
    Transport transport = mailSession.getTransport();

    String text = "Hello, World";
    String html = "<h1>" + text + "</h1>";

    MimeMessage message = new MimeMessage( mailSession );
    Multipart multipart = new MimeMultipart( "alternative" );

    MimeBodyPart textPart = new MimeBodyPart();
    textPart.setText( text, "utf-8" );

    MimeBodyPart htmlPart = new MimeBodyPart();
    htmlPart.setContent( html, "text/html; charset=utf-8" );

    multipart.addBodyPart( textPart );
    multipart.addBodyPart( htmlPart );
    message.setContent( multipart );

    // Unexpected output.
    System.out.println( "HTML = text/html : " + htmlPart.isMimeType( "text/html" ) );
    System.out.println( "HTML Content Type: " + htmlPart.getContentType() );

    // Required magic (violates principle of least astonishment).
    message.saveChanges();

    // Output now correct.    
    System.out.println( "TEXT = text/plain: " + textPart.isMimeType( "text/plain" ) );
    System.out.println( "HTML = text/html : " + htmlPart.isMimeType( "text/html" ) );
    System.out.println( "HTML Content Type: " + htmlPart.getContentType() );
    System.out.println( "HTML Data Handler: " + htmlPart.getDataHandler().getContentType() );
  }
}

I tried to use standard methods to determine the mime type, but I cannot retain the file extension using MimeTypeMap.getFileExtensionFromUrl(uri.getPath()). This method returned me an empty string. So I made a non-trivial solution to retain the file extension.

Here is the method returning the file extension:

private String getExtension(String fileName){
    char[] arrayOfFilename = fileName.toCharArray();
    for(int i = arrayOfFilename.length-1; i > 0; i--){
        if(arrayOfFilename[i] == '.'){
            return fileName.substring(i+1, fileName.length());
        }
    }
    return "";
}

And having retained the file extension, it is possible to get mime type like below:

public String getMimeType(File file) {
    String mimeType = "";
    String extension = getExtension(file.getName());
    if (MimeTypeMap.getSingleton().hasExtension(extension)) {
        mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
    }
    return mimeType;
}

The important thing to note here is that the mime type is not the same as the file extension. Sometimes, however, they have the same value.

https://www.iana.org/assignments/media-types/media-types.xhtml includes a list of registered Mime types, though there is nothing stopping you from making up your own, as long as you are at both the sending and the receiving end. Here is where Microsoft comes in to the picture.

Where there is a lot of confusion is the fact that operating systems have their own way of identifying file types by using the tail end of the file name, referred to as the extension. In modern operating systems, the whole name is one long string, but in more primitive operating systems, it is treated as a separate attribute.

The OS which caused the confusion is MSDOS, which had limited the extension to 3 characters. This limitation is inherited to this day in devices, such as SD cards, which still store data in the same way.

One side effect of this limitation is that some file extensions, such as .gif match their Mime Type, image/gif, while others are compromised. This includes image/jpeg whose extension is shortened to .jpg. Even in modern Windows, where the limitation is lifted, Microsoft never let the past go, and so the file extension is still the shortened version.

Given that that:

1. File Extensions are not File Types
2. Historically, some operating systems had serious file name limitations
3. Some operating systems will just go ahead and make up their own rules

The short answer is:

• Technically, there is no such thing as image/jpg, so the answer is that it is not the same as image/jpeg
• That won’t stop some operating systems and software from treating it as if it is the same

While we’re at it …

Legacy versions of Internet Explorer took the liberty of uploading jpeg files with the Mime Type of image/pjpeg, which, of course, just means more work for everybody else. They also uploaded png files as image/x-png.

This is what you have to do

var fileVariable =document.getElementsById('fileId').files[0];

If you want to check for image file types then

if(fileVariable.type.match('image.*'))
{
 alert('its an image');
}

But the first one was more helpful for my use case..

Happy coding ;)

font/woff2

For nginx add the following to the mime.types file:

font/woff2 woff2;

Old Answer

The mime type (sometime written as mimetype) for WOFF2 fonts has been proposed as application/font-woff2.

Also, if you refer to the spec (http://dev.w3.org/webfonts/WOFF2/spec/) you will see that font/woff2 is being discussed. I suspect that the filal mime type for all fonts will eventually be the more logical font/* (font/ttf, font/woff2 etc)...

N.B. WOFF2 is still in 'Working Draft' status -- not yet adopted officially.

I don't think it is a bug, Try adding the MIME type to your .htaccess file For instance, put or add the following content to your .htaccess file (which should be in the same place of your .js or above folders)

#JavaScript
AddType application/x-javascript .js

This solved my tree "Resource interpreted as other but transfered ... " warnings. Everytime you have that kind of warning it means you don't have enough info in your .htaccess file.

BTW1: Since you are modifying .htaccess file, make sure you restart your server.

BTW2: I also could clear same warnings for GIF files in Safari 4 with this:

#GIF
AddType image/gif .gif

BTW3: For other file types: see w3schools list or htaccess-guide

The standard way is to use audio/mpeg which is something like this in your PHP header function ...

header('Content-Type: audio/mpeg');

There's only one registered mediatype for SVG, and that's the one you listed, image/svg+xml. You can of course serve SVG as XML too, though browsers tend to behave differently in some scenarios if you do, for example I've seen cases where SVG used in CSS backgrounds fail to display unless served with the image/svg+xml mediatype.

application/javascript is the correct type to use but since it's not supported by IE6-8 you're going to be stuck with text/javascript. If you don't care about validity (HTML5 excluded) then just don't specify a type.

In a linked question, there's some Objective-C code to get the mime type for a file URL. I've created a Swift extension based on that Objective-C code to get the mime type:

import Foundation
import MobileCoreServices

extension URL {
    var mimeType: String? {
        guard self.pathExtension.count != 0 else {
            return nil
        }

        let pathExtension = self.pathExtension as CFString
        if let preferredIdentifier = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, pathExtension, nil) {
            guard let mimeType = UTTypeCopyPreferredTagWithClass(preferredIdentifier.takeRetainedValue(), kUTTagClassMIMEType) else {
                return nil
            }
            return mimeType.takeRetainedValue() as String
        }

        return nil
    }
}

As already posted in earlier answer, most common MIME types are configured in a webserver. For example in tomcat conf/ we have web.xml with following MIME configured:

   <mime-mapping>
      <extension>abs</extension>
      <mime-type>audio/x-mpeg</mime-type>
   </mime-mapping>
   <mime-mapping>
      <extension>ai</extension>
      <mime-type>application/postscript</mime-type>
   </mime-mapping>
   <mime-mapping>
      <extension>aif</extension>
      <mime-type>audio/x-aiff</mime-type>
   </mime-mapping>
...

Create a startup listener that kicks in when web app is started and parses this XML file and creates the ENUMS for you and binds it to servlet context for sharing downstream.

@Cherniv Thanks for the answer

This happens from time to time in Eclipse. In the "Project" menu there's a "Clean" option, that usually takes care of the problem.

You should use keyPressed if you want an immediate effect, and keyReleased if you want the effect after you release the key. You cannot use keyTyped because F5 is not a character. keyTyped is activated only when an character is pressed.

First check that the extension is properly loaded in phpinfo(); (something like sqlsrv should appear). If not, the extension isn't properly loaded. You also need to restart apache after installing an extension.

In simple way we can tell below are the difference between git and git hub and VSTS.

git: - Treat git as a engine/technology to achieve source version control to our project. Unlike TFS (again a centralized source version control ) git is distributed version control technology. That means git it actually does not mandate to have any server. Through git technology we can make our own local machine as a source code repository not required to have a centralized server always(in large scale it can have Microsoft server to push and keep our project source code). But with SVN and TFS kind version control, it is mandatory that a server be associated with it.

For example if I am a free-lance developer and I directly report to my client and there is no other developer involved, I need to keep version control of my code to roll back(any version) and commit my codes and I don't have budget to get a server and I don't have time to install and use other server in my machine as TFS server and TFS client. So, the optimal way is to install git engine and use my local machine as a repository for version controlling by git.

GitHub: - as I said previously git is a technology and used with some command / shell commands , ie git only doesn't have UI. GitHub is online product or online repository which uses git technology for their process and achieve version controls along with other functionalities like bug tracking,Project management, Support ticket management ..etc. In other words Git Hub is a wrapper build on git technology with a UI and other functionalities by other third party firm, it is actually a product owned by somebody or some group based on git technology , where as git is open source, and not marketable product.

VSTS : - VSTS is a Microsoft product for online repository keeping source version control which can be treated as an alternate to git hub. Since its of Microsoft , VSTS support both git technology and TFS(TFVC-team foundation version control). Because TFS is another old Microsoft product to achieve this version control.Gradually I assume VSTS will gradually dump TFS as git is the prominent technology in this area and it is open source.

This means the npm command is getting an HTML document instead of whatever format it is looking for. In my case, I was using sinopia. When I no longer wanted to use it, I accidentally used this command to reset the registry:

npm config set registry https://www.npmjs.com/

which was wrong, and it should have been the command already mentioned here. Read this if none of the answers solve this problem, and you can probably figure out where the incorrect URL is present and clear it off, and set the registry to the correct URL:

npm config set registry https://registry.npmjs.org

Newer versions of OpenSSL say BEGIN PRIVATE KEY because they contain the private key + an OID that identifies the key type (this is known as PKCS8 format). To get the old style key (known as either PKCS1 or traditional OpenSSL format) you can do this:

openssl rsa -in server.key -out server_new.key

Alternately, if you have a PKCS1 key and want PKCS8:

openssl pkcs8 -topk8 -nocrypt -in privkey.pem

The easiest way (offering something near what you wrote) is to use Boost.Regex, specifically regex_replace.

std::string has built in find() and replace() methods, but they are more cumbersome to work with as they require dealing with indices and string lengths.

I used FileReader to display image on click of the file upload button not using any Ajax requests. Following is the code hope it might help some one.

$(document).ready(function($) {
    $.extend( true, jQuery.fn, {        
        imagePreview: function( options ){          
            var defaults = {};
            if( options ){
                $.extend( true, defaults, options );
            }
            $.each( this, function(){
                var $this = $( this );              
                $this.bind( 'change', function( evt ){

                    var files = evt.target.files; // FileList object
                    // Loop through the FileList and render image files as thumbnails.
                    for (var i = 0, f; f = files[i]; i++) {
                        // Only process image files.
                        if (!f.type.match('image.*')) {
                        continue;
                        }
                        var reader = new FileReader();
                        // Closure to capture the file information.
                        reader.onload = (function(theFile) {
                            return function(e) {
                                // Render thumbnail.
                                    $('#imageURL').attr('src',e.target.result);                         
                            };
                        })(f);
                        // Read in the image file as a data URL.
                        reader.readAsDataURL(f);
                    }

                });
            });
        }   
    });
    $( '#fileinput' ).imagePreview();
});

REST is not a specific web service but a design concept (architecture) for managing state information. The seminal paper on this was Roy Thomas Fielding's dissertation (2000), "Architectural Styles and the Design of Network-based Software Architectures" (available online from the University of California, Irvine).

First read Ryan Tomayko's post How I explained REST to my wife; it's a great starting point. Then read Fielding's actual dissertation. It's not that advanced, nor is it long (six chapters, 180 pages)! (I know you kids in school like it short).

EDIT: I feel it's pointless to try to explain REST. It has so many concepts like scalability, visibility (stateless) etc. that the reader needs to grasp, and the best source for understanding those are the actual dissertation. It's much more than POST/GET etc.

You may use the String.split() method:

String[] tokens = str.split(",");

After that, use Double.parseDouble() method to parse the string value to a double.

double latitude = Double.parseDouble(tokens[0]);
double longitude = Double.parseDouble(tokens[1]);

Similar parse methods exist in the other wrapper classes as well - Integer, Boolean, etc.

You could try in this way.

SOAPMessage msg = messageContext.getMessage();
ByteArrayOutputStream out = new ByteArrayOutputStream();
msg.writeTo(out);
String strMsg = new String(out.toByteArray());

First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.

Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.

Instead, I would move all of the "application" content to a separate component, like a JPanel for example and simply move this between the applet or frame as required...

ps- You can use f.setLocationRelativeTo(null) to center the window on the screen ;)

Updated

You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...

Within the constructor of GalzyTable2 you are doing...

JApplet app = new JApplet(); add(app); app.init(); app.start(); 

...Why are you adding another applet to an applet??

Case in point...

Within the main method, you are trying to add the instance of JFrame to itself...

f.getContentPane().add(f, button2); 

Instead, create yourself a class that extends from something like JPanel, add your UI logical to this, using compound components if required.

Then, add this panel to whatever top level container you need.

This is really late to the party, but none of the solutions above worked for me. I didn't want the "Found total xxx records" so I added info:false to the config. When I removed that everything worked.

I should note that the first page loaded fine. When I hit next, the second page loaded, but immediately threw the above console error

Built a tiny, confirm-like vanilla js yes / no dialog.
https://www.npmjs.com/package/yesno-dialog

If you want to checkout all the files 'anywhere'

git checkout -- $(git rev-parse --show-toplevel)

Use display:none;

<div id="divCheckbox" style="display: none;">

• visibility: hidden hides the element, but it still takes up space in the layout.

• display: none removes the element completely from the document, it doesn't take up any space.

Try something like this. This should center any huge element in the middle vertically and horizontally with respect to its parent no matter both of their sizes.

.parent {
    position: relative;
    overflow: hidden;
    //optionally set height and width, it will depend on the rest of the styling used
}

.child {
    position: absolute;
    top: -9999px;
    bottom: -9999px;
    left: -9999px;
    right: -9999px;
    margin: auto;

If you are on Python3 you can also use the library PILasOPENCV which works in Python 2 and 3. Function api calls are the same as in PIL or pillow but internally it works with OpenCV and numpy to load, save and manipulate images. Have a look at https://github.com/bunkahle/PILasOPENCV or install it with pip install PILasOPENCV. Not all PIL functions have been simulated but the most common functions work.

The top 2 answers (from Adam Robinson and Andrejs Cainikovs) are kinda, sorta correct, in that they do technically work, but their explanations are wrong and so could be misleading in many cases. For example, while the SQL_Latin1_General_CP1_CI_AS collation will work in many cases, it should not be assumed to be the appropriate case-insensitive collation. In fact, given that the O.P. is working in a database with a case-sensitive (or possibly binary) collation, we know that the O.P. isn't using the collation that is the default for so many installations (especially any installed on an OS using US English as the language): SQL_Latin1_General_CP1_CI_AS. Sure, the O.P. could be using SQL_Latin1_General_CP1_CS_AS, but when working with VARCHAR data, it is important to not change the code page as it could lead to data loss, and that is controlled by the locale / culture of the collation (i.e. Latin1_General vs French vs Hebrew etc). Please see point # 9 below.

The other four answers are wrong to varying degrees.

I will clarify all of the misunderstandings here so that readers can hopefully make the most appropriate / efficient choices.

1. Do not use UPPER(). That is completely unnecessary extra work. Use a COLLATE clause. A string comparison needs to be done in either case, but using UPPER() also has to check, character by character, to see if there is an upper-case mapping, and then change it. And you need to do this on both sides. Adding COLLATE simply directs the processing to generate the sort keys using a different set of rules than it was going to by default. Using COLLATE is definitely more efficient (or "performant", if you like that word :) than using UPPER(), as proven in this test script (on PasteBin).

   There is also the issue noted by @Ceisc on @Danny's answer:

   In some languages case conversions do not round-trip. i.e. LOWER(x) != LOWER(UPPER(x)).

   The Turkish upper-case "I" is the common example.

2. No, collation is not a database-wide setting, at least not in this context. There is a database-level default collation, and it is used as the default for altered and newly created columns that do not specify the COLLATE clause (which is likely where this common misconception comes from), but it does not impact queries directly unless you are comparing string literals and variables to other string literals and variables, or you are referencing database-level meta-data.

3. No, collation is not per query.

4. Collations are per predicate (i.e. something operand something) or expression, not per query. And this is true for the entire query, not just the WHERE clause. This covers JOINs, GROUP BY, ORDER BY, PARTITION BY, etc.

5. No, do not convert to VARBINARY (e.g.convert(varbinary, myField) = convert(varbinary, 'sOmeVal')) for the following reasons:

   1. that is a binary comparison, which is not case-insensitive (which is what this question is asking for)
   2. if you do want a binary comparison, use a binary collation. Use one that ends with _BIN2 if you are using SQL Server 2008 or newer, else you have no choice but to use one that ends with _BIN. If the data is NVARCHAR then it doesn't matter which locale you use as they are all the same in that case, hence Latin1_General_100_BIN2 always works. If the data is VARCHAR, you must use the same locale that the data is currently in (e.g. Latin1_General, French, Japanese_XJIS, etc) because the locale determines the code page that is used, and changing code pages can alter the data (i.e. data loss).
   3. using a variable-length datatype without specifying the size will rely on the default size, and there are two different defaults depending on the context where the datatype is being used. It is either 1 or 30 for string types. When used with CONVERT() it will use the 30 default value. The danger is, if the string can be over 30 bytes, it will get silently truncated and you will likely get incorrect results from this predicate.
   4. Even if you want a case-sensitive comparison, binary collations are not case-sensitive (another very common misconception).

6. No, LIKE is not always case-sensitive. It uses the collation of the column being referenced, or the collation of the database if a variable is compared to a string literal, or the collation specified via the optional COLLATE clause.

7. LCASE is not a SQL Server function. It appears to be either Oracle or MySQL. Or possibly Visual Basic?

8. Since the context of the question is comparing a column to a string literal, neither the collation of the instance (often referred to as "server") nor the collation of the database have any direct impact here. Collations are stored per each column, and each column can have a different collation, and those collations don't need to be the same as the database's default collation or the instance's collation. Sure, the instance collation is the default for what a newly created database will use as its default collation if the COLLATE clause wasn't specified when creating the database. And likewise, the database's default collation is what an altered or newly created column will use if the COLLATE clause wasn't specified.

9. You should use the case-insensitive collation that is otherwise the same as the collation of the column. Use the following query to find the column's collation (change the table's name and schema name):

   SELECT col.*
   FROM   sys.columns col
   WHERE  col.[object_id] = OBJECT_ID(N'dbo.TableName')
   AND    col.[collation_name] IS NOT NULL;
   

   Then just change the _CS to be _CI. So, Latin1_General_100_CS_AS would become Latin1_General_100_CI_AS.

   If the column is using a binary collation (ending in _BIN or _BIN2), then find a similar collation using the following query:

   SELECT *
   FROM   sys.fn_helpcollations() col
   WHERE  col.[name] LIKE N'{CurrentCollationMinus"_BIN"}[_]CI[_]%';
   

   For example, assuming the column is using Japanese_XJIS_100_BIN2, do this:

   SELECT *
   FROM   sys.fn_helpcollations() col
   WHERE  col.[name] LIKE N'Japanese_XJIS_100[_]CI[_]%';

I think it's perfectly explained in item 25 of Scott Meyers' Effective Modern C++. Here's an excerpt:

The part of the Standard blessing the RVO goes on to say that if the conditions for the RVO are met, but compilers choose not to perform copy elision, the object being returned must be treated as an rvalue. In effect, the Standard requires that when the RVO is permitted, either copy elision takes place or std::move is implicitly applied to local objects being returned.

Here, RVO refers to return value optimization, and if the conditions for the RVO are met means returning the local object declared inside the function that you would expect to do the RVO, which is also nicely explained in item 25 of his book by referring to the standard (here the local object includes the temporary objects created by the return statement). The biggest take away from the excerpt is either copy elision takes place or std::move is implicitly applied to local objects being returned. Scott mentions in item 25 that std::move is implicitly applied when the compiler choose not to elide the copy and the programmer should not explicitly do so.

In your case, the code is clearly a candidate for RVO as it returns the local object p and the type of p is the same as the return type, which results in copy elision. And if the compiler chooses not to elide the copy, for whatever reason, std::move would've kicked in to line 1.

• Create a char array from your string
• Loop through the array, adding a space +" " after each item in the array(except the last one, maybe)
• BOOM...done!!

In more recent browsers code like below may be enough.

<object data="https://www.w3.org/TR/PNG/iso_8859-1.txt" width="300" height="200">_x000D_
Not supported_x000D_
</object>

Here is something cool if you want to go the extra mile with this. in the url, you can use a link or save an image png and use the path. for example:

url('assets/imgs/theGoods.png');

below is the code:

.cursor{
  cursor:url(http://www.icon100.com/up/3772/128/425-hand-pointer.png), auto;
}

So this will only work under the size 128 X 128, any bigger and the image wont load. But you can practically use any image you want! This would be consider pure css3, and some html. all you got to do in html is

<div class='cursor'></div>

and only in that div, that cursor will show. So I usually add it to the body tag.

The performance difference between the two is very much implementation dependent - if you compare a badly implemented std::vector to an optimal array implementation, the array would win, but turn it around and the vector would win...

As long as you compare apples with apples (either both the array and the vector have a fixed number of elements, or both get resized dynamically) I would think that the performance difference is negligible as long as you follow got STL coding practise. Don't forget that using standard C++ containers also allows you to make use of the pre-rolled algorithms that are part of the standard C++ library and most of them are likely to be better performing than the average implementation of the same algorithm you build yourself.

That said, IMHO the vector wins in a debug scenario with a debug STL as most STL implementations with a proper debug mode can at least highlight/cathc the typical mistakes made by people when working with standard containers.

Oh, and don't forget that the array and the vector share the same memory layout so you can use vectors to pass data to legacy C or C++ code that expects basic arrays. Keep in mind that most bets are off in that scenario, though, and you're dealing with raw memory again.

Simply delete that column using: del df['column_name']

You can access your log files using Heroku's Command Line Interface (CLI Usage).

If Heroku's CLI is installed and you know your application name (like https://myapp.herokuapp.com/), then you can run the following command:

heroku logs --tail --app=myapp

You can also access the logs in a real-time stream using:

heroku logs --source app --tail --app=myapp

If the logs tell you something like this:

npm ERR! A complete log of this run can be found in:

npm ERR! /app/.npm/_logs/2017-07-11T08_29_45_291Z-debug.log

Then you can also access them using the bash terminal via Heroku CLI:

heroku run bash --app=myapp
less ./.npm/_logs/2017-07-11T08_29_45_291Z-debug.log

Here I came up with universal method to navigate from any place to root.

1. You create a new Class file with this class, so that it's accessible from anywhere in your project:

   import UIKit
   
   class SharedControllers
   {
       static func navigateToRoot(viewController: UIViewController)
       {
           var nc = viewController.navigationController
   
           // If this is a normal view with NavigationController, then we just pop to root.
           if nc != nil
           {
               nc?.popToRootViewControllerAnimated(true)
               return
           }
   
           // Most likely we are in Modal view, so we will need to search for a view with NavigationController.
           let vc = viewController.presentingViewController
   
           if nc == nil
           {
               nc = viewController.presentingViewController?.navigationController
           }
   
           if nc == nil
           {
               nc = viewController.parentViewController?.navigationController
           }
   
           if vc is UINavigationController && nc == nil
           {
               nc = vc as? UINavigationController
           }
   
           if nc != nil
           {
               viewController.dismissViewControllerAnimated(false, completion:
                   {
                       nc?.popToRootViewControllerAnimated(true)
               })
           }
       }
   }
   

2. Usage from anywhere in your project:

   {
       ...
       SharedControllers.navigateToRoot(self)
       ...
   }
   

Python syntax does permit more than one statement on a line, separated by semicolon (;). However, limiting each line to one statement makes it easier for a human to follow a program's logic when reading through it.

So, another way of solving this issue, is to understand why the lint message is there and not put more than one statement on a line.

Yes, you may find it easier to write multiple statements per line, however, Pylint is for every other reader of your code not just you.

android:drawableLeft is always keeping android:paddingLeft as a distance from the left border. When the button is not set to android:width="wrap_content", it will always hang to the left!

With Android 4.0 (API level 14) you can use android:drawableStart attribute to place a drawable at the start of the text. The only backward compatible solution I've come up with is using an ImageSpan to create a Text+Image Spannable:

Button button = (Button) findViewById(R.id.button);
Spannable buttonLabel = new SpannableString(" Button Text");
buttonLabel.setSpan(new ImageSpan(getApplicationContext(), R.drawable.icon,      
    ImageSpan.ALIGN_BOTTOM), 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
button.setText(buttonLabel);

In my case I needed to also adjust the android:gravity attribute of the Button to make it look centered:

<Button
  android:id="@+id/button"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:minHeight="32dp"
  android:minWidth="150dp"
  android:gravity="center_horizontal|top" />

Html:

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<meta name="x" content="xx" />

vs Php:

<?php header('Content-type: text/html; charset=ISO-8859-1'); ?>
<!DOCTYPE HTML>
<html>
<head>
<meta name="x" content="xx" />

I have also used a non-generic version, using the new keyword:

public interface IMetadata
{
    Type DataType { get; }

    object Data { get; }
}

public interface IMetadata<TData> : IMetadata
{
    new TData Data { get; }
}

Explicit interface implementation is used to allow both Data members:

public class Metadata<TData> : IMetadata<TData>
{
    public Metadata(TData data)
    {
       Data = data;
    }

    public Type DataType
    {
        get { return typeof(TData); }
    }

    object IMetadata.Data
    {
        get { return Data; }
    }

    public TData Data { get; private set; }
}

You could derive a version targeting value types:

public interface IValueTypeMetadata : IMetadata
{

}

public interface IValueTypeMetadata<TData> : IMetadata<TData>, IValueTypeMetadata where TData : struct
{

}

public class ValueTypeMetadata<TData> : Metadata<TData>, IValueTypeMetadata<TData> where TData : struct
{
    public ValueTypeMetadata(TData data) : base(data)
    {}
}

This can be extended to any kind of generic constraints.

Since no answer on this page handles mixed text well, I made my own version:

import java.util.regex.Matcher;
import java.util.regex.Pattern;

class Main {
    static double parseVersion(String v) {
        if (v.isEmpty()) {
            return 0;
        }
        Pattern p = Pattern.compile("^(\\D*)(\\d*)(\\D*)$");
        Matcher m = p.matcher(v);
        m.find();
        if (m.group(2).isEmpty()) {
            // v1.0.0.[preview]
            return -1;
        }
        double i = Integer.parseInt(m.group(2));
        if (!m.group(3).isEmpty()) {
            // v1.0.[0b]
            i -= 0.1;
        }
        return i;
    }

    public static int versionCompare(String str1, String str2) {
        String[] v1 = str1.split("\\.");
        String[] v2 = str2.split("\\.");
        int i = 0;
        for (; i < v1.length && i < v2.length; i++) {
            double iv1 = parseVersion(v1[i]);
            double iv2 = parseVersion(v2[i]);

            if (iv1 != iv2) {
                return iv1 - iv2 < 0 ? -1 : 1;
            }
        }
        if (i < v1.length) {
            // "1.0.1", "1.0"
            double iv1 = parseVersion(v1[i]);
            return iv1 < 0 ? -1 : (int) Math.ceil(iv1);
        }
        if (i < v2.length) {
            double iv2 = parseVersion(v2[i]);
            return -iv2 < 0 ? -1 : (int) Math.ceil(iv2);
        }
        return 0;
    }


    public static void main(String[] args) {
        System.out.println("versionCompare(v1.0.0, 1.0.0)");
        System.out.println(versionCompare("v1.0.0", "1.0.0")); // 0

        System.out.println("versionCompare(v1.0.0b, 1.0.0)");
        System.out.println(versionCompare("v1.0.0b", "1.0.0")); // -1

        System.out.println("versionCompare(v1.0.0.preview, 1.0.0)");
        System.out.println(versionCompare("v1.0.0.preview", "1.0.0")); // -1

        System.out.println("versionCompare(v1.0, 1.0.0)");
        System.out.println(versionCompare("v1.0", "1.0.0")); // 0

        System.out.println("versionCompare(ver1.0, 1.0.1)");
        System.out.println(versionCompare("ver1.0", "1.0.1")); // -1
    }
}

It still falls short on cases where you need to compare "alpha" with "beta" though.

As already mentioned the correct way to have a space in an XML file is by using \u0020 which is the unicode character for a space.

Example:

<string name="spelatonertext3">-4,\u00205,\u0020-5,\u00206,\u0020-6</string>

Other suggestions have said to use   or   but there is two downsides to this. The first downside is that these are ASCII characters so you are relying on something like a TextView to parse them. The second downside is that   can sometimes cause strange wrapping in TextViews.

You can set also blank condition, in place of set null

         var isDisable=true;

   

          RaisedButton(
              padding: const EdgeInsets.all(20),
              textColor: Colors.white,
              color: Colors.green,
              onPressed:  isDisable
                  ? () => (){} : myClickingData(),
              child: Text('Button'),
            )

A new line is just whitespace to the browser and won't be treated any different to a normal space (" "). To get a new line, you must insert <BR /> elements.

Another attempt to solve the problem: Type the text into the textarea and then add some JavaScript behind a button to convert the invisible characters to something readable and dump the result to a DIV. That will tell you what your browser wants.

for people who want to use UIDatePicker as input:

UIDatePicker *timePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 250, 0, 0)];
[timePicker addTarget:self action:@selector(pickerChanged:)
     forControlEvents:UIControlEventValueChanged];
[_textField setInputView:timePicker];

// pickerChanged:
- (void)pickerChanged:(id)sender {
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"d/M/Y"];
    _textField.text = [formatter stringFromDate:[sender date]];
}

SQlite3 has a method named row_factory. This method would allow you to access the values by column name.

If you want a CSRNG to generate random numbers between a min and max, this is for you. It will initialize Random classes with secure random seeds.

    class SecureRandom : Random
    {
        public static byte[] GetBytes(ulong length)
        {
            RNGCryptoServiceProvider RNG = new RNGCryptoServiceProvider();
            byte[] bytes = new byte[length];
            RNG.GetBytes(bytes);
            RNG.Dispose();
            return bytes;
        }
        public SecureRandom() : base(BitConverter.ToInt32(GetBytes(4), 0))
        {

        }
        public int GetRandomInt(int min, int max)
        {
            int treashold = max - min;
            if(treashold != Math.Abs(treashold))
            {
                throw new ArithmeticException("The minimum value can't exceed the maximum value!");
            }
            if (treashold == 0)
            {
                throw new ArithmeticException("The minimum value can't be the same as the maximum value!");
            }
            return min + (Next() % treashold);
        }
        public static int GetRandomIntStatic(int min, int max)
        {
            int treashold = max - min;
            if (treashold != Math.Abs(treashold))
            {
                throw new ArithmeticException("The minimum value can't exceed the maximum value!");
            }
            if(treashold == 0)
            {
                throw new ArithmeticException("The minimum value can't be the same as the maximum value!");
            }
            return min + (BitConverter.ToInt32(GetBytes(4), 0) % treashold);
        }
    }

All the answers above came with it's own issues. Easiest/cleanest way IMO is to create a helper

MVC5 Razor

App_Code/Helpers.cshtml

@helper CheckBoxFor(WebViewPage page, string propertyName, bool? value, string htmlAttributes = null)
{
    if (value == null)
    {
        <div class="checkbox-nullable">
            <input type="checkbox" @page.Html.Raw(htmlAttributes)>
        </div>
    }
    else if (value == true)
    {
        <input type="checkbox" value="true" @page.Html.Raw(htmlAttributes) checked>
    }
    else
    {
        <input type="checkbox" value="false" @page.Html.Raw(htmlAttributes)>
    }
}

Usage

@Helpers.CheckBoxFor(this, "IsPaymentRecordOk", Model.IsPaymentRecordOk)

In my scenario, a nullable checkbox means that a staff member had not yet asked the question to the client, so it's wrapped in a .checkbox-nullable so that you may style appropriately and help the end-user identify that it is neither true nor false

CSS

.checkbox-nullable {
    border: 1px solid red;
    padding: 3px;
    display: inline-block;
}

Character varying is different than text. Try running

ALTER TABLE product_product ALTER COLUMN code TYPE text;

That will change the column type to text, which is limited to some very large amount of data (you would probably never actually hit it.)

I have just found a really good example of how to do this here: http://developer.android.com/reference/android/webkit/WebView.html . You just need to change the setprogress from:

activity.setProgress(progress * 1000);

to

activity.setProgress(progress * 100);

Getting the element type the jQuery way:

var elementType = $(this).prev().prop('nodeName');

doing the same without jQuery

var elementType = this.previousSibling.nodeName;

Checking for specific element type:

var is_element_input = $(this).prev().is("input"); //true or false

Just like some other answers, I recommend to use String.format() and BigInteger. But to interpret the byte array as big-endian binary representation instead of two's-complement binary representation (with signum and incomplete use of possible hex values range) use BigInteger(int signum, byte[] magnitude), not BigInteger(byte[] val).

For example, for a byte array of length 8 use:

String.format("%016X", new BigInteger(1,bytes))

Advantages:

• leading zeros
• no signum
• only built-in functions
• only one line of code

Disadvantage:

• there might be more efficient ways to do that

Example:

byte[] bytes = new byte[8];
Random r = new Random();
System.out.println("big-endian       | two's-complement");
System.out.println("-----------------|-----------------");
for (int i = 0; i < 10; i++) {
    r.nextBytes(bytes);
    System.out.print(String.format("%016X", new BigInteger(1,bytes)));
    System.out.print(" | ");
    System.out.print(String.format("%016X", new BigInteger(bytes)));
    System.out.println();
}

Example output:

big-endian       | two's-complement
-----------------|-----------------
3971B56BC7C80590 | 3971B56BC7C80590

console.log works.

By default on iOS, it logs to the debug pane inside Xcode.

From the IOS simulator press (?+D) and press Remote JS Debugging. This will open a resource, http://localhost:8081/debugger-ui on localhost. From there use Chrome Developer tools javascript console to view console.log

You can use jQuery's hover function.

You just need to add the class open when the mouse enters and remove the class when the mouse leaves the dropdown.

Here's my code:

$(function(){
    $('.dropdown').hover(function() {
        $(this).addClass('open');
    },
    function() {
        $(this).removeClass('open');
    });
});

// Export to CSV
if($_GET['action'] == 'export') {

  $rsSearchResults = mysql_query($sql, $db) or die(mysql_error());

  $out = '';
  $fields = mysql_list_fields('database','table',$db);
  $columns = mysql_num_fields($fields);

  // Put the name of all fields
  for ($i = 0; $i < $columns; $i++) {
    $l=mysql_field_name($fields, $i);
    $out .= '"'.$l.'",';
  }
  $out .="\n";

  // Add all values in the table
  while ($l = mysql_fetch_array($rsSearchResults)) {
    for ($i = 0; $i < $columns; $i++) {
      $out .='"'.$l["$i"].'",';
    }
    $out .="\n";
  }
  // Output to browser with appropriate mime type, you choose ;)
  header("Content-type: text/x-csv");
  //header("Content-type: text/csv");
  //header("Content-type: application/csv");
  header("Content-Disposition: attachment; filename=search_results.csv");
  echo $out;
  exit;
}

Hmm, best way is to use this command:

du -h -x / | sort -hr >> /home/log_size.txt

Then you will be able to get all sizes folders over all your server. Easy to help to you to find the biggest sizes.

After uninstalling IIS on Windows 7, I continued to have IIS Welcome page. The solution was to clear the cache of my web browsers. It works fine now. I didn't change anything else. Sorry for my english, if it is not perfect.

If you are asked to enter the full pathname for the JDK, click Browse and find it. For example, on a Windows system the path might have a name similar to C:\Program Files\Java\jdk1.7.0_51.

function isMobileDev(){
    if(isset($_SERVER['HTTP_USER_AGENT']) and !empty($_SERVER['HTTP_USER_AGENT'])){
       $user_ag = $_SERVER['HTTP_USER_AGENT'];
       if(preg_match('/(Mobile|Android|Tablet|GoBrowser|[0-9]x[0-9]*|uZardWeb\/|Mini|Doris\/|Skyfire\/|iPhone|Fennec\/|Maemo|Iris\/|CLDC\-|Mobi\/)/uis',$user_ag)){
          return true;
       };
    };
    return false;
}

I am new into all of this. Maybe you can just add/change this HTML code. Without need for CSS. It worked for me :)

width="100%" height="height"

fs.exist() is deprecated. So I have used fs.stat() to check the directory status. If the directory does not exist fs.stat() throw an error with message like 'no such file or directory'. Then I have created a directory.

const fs = require('fs').promises;
    
const dir = './dir';
fs.stat(dir).catch(async (err) => {
  if (err.message.includes('no such file or directory')) {
    await fs.mkdir(dir);
  }
});

You can also get the body of triggers as following:

SELECT      o.[name],
            c.[text]
FROM        sys.objects AS o
INNER JOIN  sys.syscomments AS c
ON      o.object_id = c.id
WHERE   o.[type] = 'TR'

DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document document = db.parse(new ByteArrayInputStream(xmlString.getBytes("UTF-8"))); //remove the parameter UTF-8 if you don't want to specify the Encoding type.

this works well for me even though the XML structure is complex.

And please make sure your xmlString is valid for XML, notice the escape character should be added "\" at the front.

The main problem might not come from the attributes.

        Dim result2 = From s In mySession.Query(Of CSucursal)()
                      Where (From c In mySession.Query(Of CCiudad)()
                             From cs In mySession.Query(Of CCiudadSucursal)()
                             Where cs.id_ciudad Is c
                             Where cs.id_sucursal Is s
                             Where c.id = IdCiudad
                             Where s.accion <> "E" AndAlso s.accion <> Nothing

Cookie

• is a small amount of data saved in the browser (client-side)

• can be set from PHP with setcookie and then will be sent to the client's browser (HTTP response header Set-cookie)

• can be set directly client-side in Javascript: document.cookie = 'foo=bar';

• if no expiration date is set, by default, it will expire when the browser is closed.
  Example: go on http://example.com, open the Console, do document.cookie = 'foo=bar';. Close the tab, reopen the same website, open the Console, do document.cookie: you will see foo=bar is still there. Now close the browser and reopen it, re-visit the same website, open the Console ; you will see document.cookie is empty.

• you can also set a precise expiration date other than "deleted when browser is closed".

• the cookies that are stored in the browser are sent to the server in the headers of every request of the same website (see Cookie). You can see this for example with Chrome by opening Developer tools > Network, click on the request, see Headers:

  

• can be read client-side with document.cookie

• can be read server-side with $_COOKIE['foo']

• Bonus: it can also be set/get with another language than PHP. Example in Python with "bottle" micro-framework (see also here):

  from bottle import get, run, request, response
  @get('/')
  def index():
      if request.get_cookie("visited"):
          return "Welcome back! Nice to see you again"
      else:

Session

• is some data relative to a browser session saved server-side

• each server-side language may implement it in a different way

• in PHP, when session_start(); is called:

  • a random ID is generated by the server, e.g. jo96fme9ko0f85cdglb3hl6ah6
  • a file is saved on the server, containing the data: e.g. /var/lib/php5/sess_jo96fme9ko0f85cdglb3hl6ah6

  • the session ID is sent to the client in the HTTP response headers, using the traditional cookie mechanism detailed above: Set-Cookie: PHPSESSID=jo96fme9ko0f85cdglb3hl6ah6; path=/:

    

    (it can also be be sent via the URL instead of cookie but not the default behaviour)

  • you can see the session ID on client-side with document.cookie:

    

• the PHPSESSID cookie is set with no expiration date, thus it will expire when the browser is closed. Thus "sessions" are not valid anymore when the browser is closed / reopened.

• can be set/read in PHP with $_SESSION

• the client-side does not see the session data but only the ID: do this in index.php:

  <?php
  session_start();
  $_SESSION["abc"]="def";
  ?>
  

  The only thing that is seen on client-side is (as mentioned above) the session ID:

  

• because of this, session is useful to store data that you don't want to be seen or modified by the client

• you can totally avoid using sessions if you want to use your own database + IDs and send an ID/token to the client with a traditional Cookie

just change this line

[img setImage:[UIImage imageNamed:@"anyImageName"]];

with following line

img = [UIImage imageNamed:@"anyImageName"];

There is no way to do this in the GitHub web application. I believe to only way to do this is in the command line using git mv <old name> <new name> or by using a Git client(like SourceTree).

You can directly use following javascript

((JavascriptExecutor)driver).executeScript("document.getElementById('fromDate').setAttribute('value','10 Jan 2013')")

Combine them. Literally combine them; attach them together without any punctuation.

$('.myclass[reference="12345"]')

Your first selector looks for elements with the attribute value, contained in elements with the class.
The space is being interpreted as the descendant selector.

Your second selector, like you said, looks for elements with either the attribute value, or the class, or both.
The comma is being interpreted as the multiple selector operator — whatever that means (CSS selectors don't have a notion of "operators"; the comma is probably more accurately known as a delimiter).

Make sure you have .NET 4.6.2 Developer Pack for VS installed and then pull in System.ValueTuple package from NuGet.

You could pass a Class<T> in.

private void foo(Class<?> cls) {
    if (cls == String.class) { ... }
    else if (cls == int.class) { ... }
}

private void bar() {
    foo(String.class);
}

Update: the OOP way depends on the functional requirement. Best bet would be an interface defining foo() and two concrete implementations implementing foo() and then just call foo() on the implementation you've at hand. Another way may be a Map<Class<?>, Action> which you could call by actions.get(cls). This is easily to be combined with an interface and concrete implementations: actions.get(cls).foo().

If you are using bootstrap and font-awesome then it is easy, no need to write a single line of new code, just add fa-Nx, as big you want, See the demo

<span class="glyphicon glyphicon-globe"></span>
<span class="glyphicon glyphicon-globe fa-lg"></span>
<span class="glyphicon glyphicon-globe fa-2x"></span>
<span class="glyphicon glyphicon-globe fa-3x"></span>
<span class="glyphicon glyphicon-globe fa-4x"></span>
<span class="glyphicon glyphicon-globe fa-5x"></span>

You can use the --ignore-table option. So you could do

mysqldump -u USERNAME -pPASSWORD DATABASE --ignore-table=DATABASE.table1 > database.sql

There is no whitespace after -p (this is not a typo).

To ignore multiple tables, use this option multiple times, this is documented to work since at least version 5.0.

If you want an alternative way to ignore multiple tables you can use a script like this:

#!/bin/bash
PASSWORD=XXXXXX
HOST=XXXXXX
USER=XXXXXX
DATABASE=databasename
DB_FILE=dump.sql
EXCLUDED_TABLES=(
table1
table2
table3
table4
tableN   
)
 
IGNORED_TABLES_STRING=''
for TABLE in "${EXCLUDED_TABLES[@]}"
do :
   IGNORED_TABLES_STRING+=" --ignore-table=${DATABASE}.${TABLE}"
done

echo "Dump structure"
mysqldump --host=${HOST} --user=${USER} --password=${PASSWORD} --single-transaction --no-data --routines ${DATABASE} > ${DB_FILE}

echo "Dump content"
mysqldump --host=${HOST} --user=${USER} --password=${PASSWORD} ${DATABASE} --no-create-info --skip-triggers ${IGNORED_TABLES_STRING} >> ${DB_FILE}

You can do the following steps:

1. First isolate the column (by inserting a blank column before and/or after the column you want to count the unique values if there are any adjacent columns;

2. Then select the whole column, go to 'Data' > 'Advanced Filter' and check the checkbox 'Unique records only'. This will hide all non-unique records so you can count the unique ones by selecting the whole column.

this code worked for me

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main_menu,menu);
    if (Application.sharedPreferences.getInt("type",1) == 2)
    {
        menuItem = menu.findItem(R.id.menu_travel_orders);
        menuItem.setVisible(false);
    }
    return super.onCreateOptionsMenu(menu);
}

Go to SETTINGS->Location and Security-> Device Administrator and deselect the admin which you want to uninstall.

Now uninstall the application. If it still says you need to deactivate the application before uninstalling, you may need to Force Stop the application before uninstalling.

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

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

Swift 4

I think, there are two ways.

1. NSRange(range, in: )

2. NSRange(location:, length: )

Sample code:

let attributedString = NSMutableAttributedString(string: "Sample Text 12345", attributes: [.font : UIFont.systemFont(ofSize: 15.0)])

// NSRange(range, in: )
if let range = attributedString.string.range(of: "Sample")  {
    attributedString.addAttribute(.foregroundColor, value: UIColor.orange, range: NSRange(range, in: attributedString.string))
}

// NSRange(location: , length: )
if let range = attributedString.string.range(of: "12345") {
    attributedString.addAttribute(.foregroundColor, value: UIColor.green, range: NSRange(location: range.lowerBound.encodedOffset, length: range.upperBound.encodedOffset - range.lowerBound.encodedOffset))
}

Screen Shot:

I know this has been a while, however, Iam wondering whether the best way to handle this would be to utilize the be session variable(s)

In your myFile.php you'd have

<?php 

$MySomeVAR = $_SESSION['SomeVar'];

?> 

And in the calling file

<?php

session_start(); 
$_SESSION['SomeVar'] = $SomeVAR;
include('myFile.php');
echo $MySomeVAR;

?> 

Would this circumvent the "suggested" need to Functionize the whole process?

In the early days...like before the 90s...the processors weren't able to do multi tasks that efficiently...coz a single processor could handle just a single task...so when we used to say that my antivirus,microsoft word,vlc,etc. softwares are all running at the same time...that isn't actually true. When I said a processor could handle a single process at a time...I meant it. It actually would process a single task...then it used to pause that task...take another task...complete it if its a short one or again pause it and add it to the queue...then the next. But this 'pause' that I mentioned was so small (appx. 1ns) that you didn't understand that the task has been paused. Eg. On vlc while listening to music there are other apps running simultaneously but as I told you...one program at a time...so the vlc is actually pausing in between for ns so you dont underatand it but the music is actually stopping in between.

But this was about the old processors...

Now-a- days processors ie 3rd gen pcs have multi cored processors. Now the 'cores' can be compared to a 1st or 2nd gen processors itself...embedded onto a single chip, a single processor. So now we understood what are cores ie they are mini processors which combine to become a processor. And each core can handle a single process at a time or multi threads as designed for the OS. And they folloq the same steps as I mentioned above about the single processor.

Eg. A i7 6gen processor has 8 cores...ie 8 mini processors in 1 i7...ie its speed is 8x times the old processors. And this is how multi tasking can be done.

There could be hundreds of cores in a single processor Eg. Intel i128.

I hope I explaned this well.

Everything is possible only if there is enough time to research :)

What I got to do is like having people that I iterate into a ui:repeat and display names and other fields in inputs. But one of fields was singleSelect - A and depending on it value update another input - B. even ui:repeat do not have id I put and it appeared in the DOM tree

<ui:repeat id="peopleRepeat"
value="#{myBean.people}"
var="person" varStatus="status">

Than the ids in the html were something like:

myForm:peopleRepeat:0:personType
myForm:peopleRepeat:1:personType

Than in the view I got one method like:

<p:ajax event="change"
listener="#{myBean.onPersonTypeChange(person, status.index)}"/>

And its implementation was in the bean like:

String componentId = "myForm:peopleRepeat" + idx + "personType";
PrimeFaces.current().ajax().update(componentId);

So this way I updated the element from the bean with no issues. PF version 6.2

Good luck and happy coding :)

In theory, malloc gets memory from the operating system for this application. However, since you may only want 4 bytes, and the OS needs to work in pages (often 4k), malloc does a little more than that. It takes a page, and puts it's own information in there so it can keep track of what you have allocated and freed from that page.

When you allocate 4 bytes, for instance, malloc gives you a pointer to 4 bytes. What you may not realize is that the memory 8-12 bytes before your 4 bytes is being used by malloc to make a chain of all the memory you have allocated. When you call free, it takes your pointer, backs up to where it's data is, and operates on that.

When you free memory, malloc takes that memory block off the chain... and may or may not return that memory to the operating system. If it does, than accessing that memory will probably fail, as the OS will take away your permissions to access that location. If malloc keeps the memory ( because it has other things allocated in that page, or for some optimization ), then the access will happen to work. It's still wrong, but it might work.

DISCLAIMER: What I described is a common implementation of malloc, but by no means the only possible one.

WPF version:

public class LineSegment
{
    private readonly Vector _offset;
    private readonly Vector _vector;

    public LineSegment(Point start, Point end)
    {
        _offset = (Vector)start;
        _vector = (Vector)(end - _offset);
    }

    public double DistanceTo(Point pt)
    {
        var v = (Vector)pt - _offset;

        // first, find a projection point on the segment in parametric form (0..1)
        var p = (v * _vector) / _vector.LengthSquared;

        // and limit it so it lays inside the segment
        p = Math.Min(Math.Max(p, 0), 1);

        // now, find the distance from that point to our point
        return (_vector * p - v).Length;
    }
}

Well, the first question is easy. There are many ens (Englishes) but (mostly) only one US English. One would guess there are en-CN, en-GB, en-AU. Guess there might even be Austrian English but that's more yes you can than yes there is.

This is a fix for people who are not using maven. You also need to add standard.jar to your lib folder for the core tag library to work. Works for jstl version 1.1.

<%@taglib prefix="core" uri="http://java.sun.com/jsp/jstl/core"%>

The nature of wanting to include the row where A == 5 and all rows upto but not including the row where A == 8 means we will end up using iloc (loc includes both ends of slice).

In order to get the index labels we use idxmax. This will return the first position of the maximum value. I run this on a boolean series where A == 5 (then when A == 8) which returns the index value of when A == 5 first happens (same thing for A == 8).

Then I use searchsorted to find the ordinal position of where the index label (that I found above) occurs. This is what I use in iloc.

i5, i8 = df.index.searchsorted([df.A.eq(5).idxmax(), df.A.eq(8).idxmax()])
df.iloc[i5:i8]

numpy

you can further enhance this by using the underlying numpy objects the analogous numpy functions. I wrapped it up into a handy function.

def find_between(df, col, v1, v2):
    vals = df[col].values
    mx1, mx2 = (vals == v1).argmax(), (vals == v2).argmax()
    idx = df.index.values
    i1, i2 = idx.searchsorted([mx1, mx2])
    return df.iloc[i1:i2]

find_between(df, 'A', 5, 8)

timing

Are you looking for

#if BOOST_VERSION != "1.2"
#error "Bad version"
#endif

Not great if BOOST_VERSION is a string, like I've assumed, but there may also be individual integers defined for the major, minor and revision numbers.

For me the /**<NEWLINE> or Shift-Alt-J (or ?-?-J on a Mac) approach works best.

I dislike seeing Javadoc comments in source code that have been auto-generated and have not been updated with real content. As far as I am concerned, such javadocs are nothing more than a waste of screen space.

IMO, it is much much better to generate the Javadoc comment skeletons one by one as you are about to fill in the details.

Use this String.valueOf(value);

You could use this function which is doing the same as the eval() function, but in a simple manner, using a function.

def numeric(equation):
    if '+' in equation:
        y = equation.split('+')
        x = int(y[0])+int(y[1])
    elif '-' in equation:
        y = equation.split('-')
        x = int(y[0])-int(y[1])
    return x

Please do check Hibernate Property Name and Id Name also.

In addition to what provided in the other answers, the keyword "zorder" allows one to decide the order in which different objects are plotted vertically. E.g.:

plt.plot(x,y,zorder=1) 
plt.scatter(x,y,zorder=2)

plots the scatter symbols on top of the line, while

plt.plot(x,y,zorder=2)
plt.scatter(x,y,zorder=1)

plots the line over the scatter symbols.

See, e.g., the zorder demo

Witty example, Ryan, to end with a link to the function. Well done.

One recommendation Brian: if you wrap this code in a function, you may want to use a UriBuilder to wrap the base URL prior to the TryCreate call.

Otherwise, the base URL MUST include the scheme (where the UriBuilder will assume http://). Just a thought:

public string CombineUrl(string baseUrl, string relativeUrl) {
    UriBuilder baseUri = new UriBuilder(baseUrl);
    Uri newUri;

    if (Uri.TryCreate(baseUri.Uri, relativeUrl, out newUri))
        return newUri.ToString();
    else
        throw new ArgumentException("Unable to combine specified url values");
}

For GitLab version prior to 1.7, use:

git checkout -b name_branch

(name_branch, ex: master)

To push it to the remote repository, do:

git push -u origin name_new_branch

(name_new_branch, example: feature)

You can try this.

txt = <file_path>
txt_opn = open(txt)
print txt_opn.read()

This will give you file output.

This will give you the date in 24 hour format.

    Date date = new Date();
    date.setHours(date.getHours() + 8);
    System.out.println(date);
    SimpleDateFormat simpDate;
    simpDate = new SimpleDateFormat("kk:mm:ss");
    System.out.println(simpDate.format(date));

You could also write your own IFormatProvider, though I suppose eventually you'd have to think of a way to do the actual truncation.

The .NET Framework also supports custom formatting. This typically involves the creation of a formatting class that implements both IFormatProvider and ICustomFormatter. (msdn)

At least it would be easily reusable.

There is an article about how to implement your own IFormatProvider/ICustomFormatter here at CodeProject. In this case, "extending" an existing numeric format might be the best bet. It doesn't look too hard.

Maybe you could also use stash to store temporaly your modifications in a patch file and then reapply it (after a checkout to come back to the old version). This could be related to this other topic : How would I extract a single file (or changes to a file) from a git stash?.

I don't think you should use the data option, because this does more than just setting a default value. You're also overriding any data that's being passed to the form during creation. So basically, you're breaking support for that feature. - Which might not matter when you're letting the user create data, but does matter when you want to (someday) use the form for updating data.

See http://symfony.com/doc/current/reference/forms/types/choice.html#data

I believe it would be better to pass any default data during form creation. In the controller.

For example, you can pass in a class and define the default value in your class itself. (when using the default Symfony\Bundle\FrameworkBundle\Controller\Controller)

$form = $this->createForm(AnimalType::class, [
    'species' => 174 // this id might be substituted by an entity
]);

Or when using objects:

$dog = new Dog();
$dog->setSpecies(174); // this id might be substituted by an entity

$form = $this->createForm(AnimalType::class, $dog);

Even better when using a factory: (where dog probably extends from animal)

$form = $this->createForm(AnimalType::class, DogFactory::create());

This will enable you to separate form structure and content from each other and make your form reusable in more situations.

Or, use the preferred_choices option, but this has the side effect of moving the default option to the top of your form.

See: http://symfony.com/doc/current/reference/forms/types/choice.html#preferred-choices

$builder->add(
    'species', 
    'entity', 
    [
        'class' => 'BFPEduBundle:Item',
        'property' => 'name',
        'query_builder' => ...,
        'preferred_choices' => [174] // this id might be substituted by an entity
     ]
 );

Based on the above post i tried this and this worked fine I wanted to use the value of Map B as keys for Map A:

<c:if test="${not empty activityCodeMap and not empty activityDescMap}">
<c:forEach var="valueMap" items="${auditMap}">
<tr>
<td class="activity_white"><c:out value="${activityCodeMap[valueMap.value.activityCode]}"/></td>
<td class="activity_white"><c:out value="${activityDescMap[valueMap.value.activityDescCode]}"/></td>
<td class="activity_white">${valueMap.value.dateTime}</td>
</tr>
</c:forEach>
</c:if>

Simple way to do it in jQuery :

/* The elements we'll bind the shortcut keys to. */
var elements = "body, input, select, checkbox, textarea";

/* Bind the key short-cut 'Ctrl+S' to the save function. */
$(elements).bind ("keydown", "ctrl+space", function (e) {
    // Prevent the default operation.
    e.preventDefault ();
    // Stop processing if we're already doing something.
    console.log ("That's right , you pressed correct shortcut!");
});

What do you think this is supposed to be: ((t[1])/length) * t[1] += string

Python can't parse this, it's a syntax error.

No, Java doesn't have that ability.

It does have System.nanoTime(), but that just gives an offset from some previously known time. So whilst you can't take the absolute number from this, you can use it to measure nanosecond (or higher) precision.

Note that the JavaDoc says that whilst this provides nanosecond precision, that doesn't mean nanosecond accuracy. So take some suitably large modulus of the return value.

I used this

^(https?:\\/\\/([a-zA-z0-9]+)(\\.[a-zA-z0-9]+)(\\.[a-zA-z0-9\\/\\=\\-\\_\\?]+)?)$

Modify Mysql encryption

ALTER USER 'lcherukuri'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

use:

/^[ A-Za-z0-9_@./#&+-]*$/

You can also use the character class \w to replace A-Za-z0-9_

If you are using bootstrap then the below solution will work.

<div>
    <button type="submit" class="btn btn-primary" >Invoke User Endpoint</button>
    <button type="submit" class="btn btn-primary ml-3">Invoke Hello Endpoint</button>
</div>

The simplest way to check the existence of the column in mongo compass is :

{ 'column_name': { $exists: true } }

To surpass this error , you should start by removing all the imports of app.module.ts and have something like this :

            import { BrowserModule } from '@angular/platform-browser';
            import { HttpClientModule } from '@angular/common/http';
            import { ErrorHandler, NgModule } from '@angular/core';
            import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';
            import { SplashScreen } from '@ionic-native/splash-screen';
            import { StatusBar } from '@ionic-native/status-bar';

            import { MyApp } from './app.component';


            @NgModule({
              declarations: [
                MyApp
              ],
              imports: [
                BrowserModule,
                HttpClientModule,
                IonicModule.forRoot(MyApp)
              ],
              bootstrap: [IonicApp],
              entryComponents: [
                MyApp
              ],
              providers: [
                StatusBar,
                SplashScreen,
                {provide: ErrorHandler, useClass: IonicErrorHandler}
              ]
            })
            export class AppModule {}

Next edit your pages module , like this :

            import { NgModule } from '@angular/core';
            import { IonicPageModule } from 'ionic-angular';
            import { HomePage } from './home';

            @NgModule({
              declarations: [
                HomePage,
              ],
              imports: [
                IonicPageModule.forChild(HomePage),
              ],
              entryComponents: [HomePage]
            })
            export class HomePageModule {}

Then add annotation of IonicPage before component annotation of all the pages :

import { IonicPage } from 'ionic-angular';

@IonicPage()
@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})

Then edit your rootPage type to be string and remove the imports of pages (if there is any in your app component )

rootPage: string = 'HomePage';

Then the navigation function should be like this :

 /**
* Allow navigation to the HomePage for creating a new entry
*
* @public
* @method viewHome
* @return {None}
*/
 viewHome() : void
 {
  this.navCtrl.push('HomePage');
 }

You can find the source of this solution here : Component is part of the declaration of 2 modules

How to call this function? please view below code;

private List<FundraiserStudentListModel> GetStudentsFromExcel(HttpPostedFileBase file)
    {
        List<FundraiserStudentListModel> list = new List<FundraiserStudentListModel>();
        if (file != null)
        {
            try
            {
                using (ExcelPackage package = new ExcelPackage(file.InputStream))
                {

            }
        }
        return list;
    }

FundraiserStudentListModel here:

 public class FundraiserStudentListModel
{
    public string Name { get; set; }
    public string Email { get; set; }
    public string Phone { get; set; }
}

Following two options worked for me:

1) A function that returns the number of rows in your ResultSet.

private int resultSetCount(ResultSet resultSet) throws SQLException{
    try{
        int i = 0;
        while (resultSet.next()) {
            i++;
        }
        return i;
    } catch (Exception e){
       System.out.println("Error getting row count");
       e.printStackTrace();
    }
    return 0;
}

2) Create a second SQL statement with the COUNT option.

From MDN by setAttribute():

To set the value of a Boolean attribute, such as disabled, you can specify any value. An empty string or the name of the attribute are recommended values. All that matters is that if the attribute is present at all, regardless of its actual value, its value is considered to be true. The absence of the attribute means its value is false. By setting the value of the disabled attribute to the empty string (""), we are setting disabled to true, which results in the button being disabled.

Link to MDN

Solution

• I mean that in XHTML Strict is right disabled="disabled",
• and in HTML5 is only disabled, like <input name="myinput" disabled>
• In javascript, I set the value to true via e.disabled = true;
  or to "" via setAttribute( "disabled", "" );

Test in Chrome

var f = document.querySelectorAll( "label.disabled input" );
for( var i = 0; i < f.length; i++ )
{
    // Reference
    var e = f[ i ];

    // Actions
    e.setAttribute( "disabled", false|null|undefined|""|0|"disabled" );
    /*
        <input disabled="false"|"null"|"undefined"|empty|"0"|"disabled">
        e.getAttribute( "disabled" ) === "false"|"null"|"undefined"|""|"0"|"disabled"
        e.disabled === true
    */
    
    e.removeAttribute( "disabled" );
    /*
        <input>
        e.getAttribute( "disabled" ) === null
        e.disabled === false
    */

    e.disabled = false|null|undefined|""|0;
    /*
        <input>
        e.getAttribute( "disabled" ) === null|null|null|null|null
        e.disabled === false
    */

    e.disabled = true|" "|"disabled"|1;
    /*
        <input disabled>
        e.getAttribute( "disabled" ) === ""|""|""|""
        e.disabled === true
    */
}

In case that you're using a directive like me this is how it works when you need the two data way binding for example after updating an attribute in any model or collection:

angular.module('yourApp').directive('setSurveyInEditionMode', setSurveyInEditionMode)

function setSurveyInEditionMode() {
  return {
    restrict: 'A',
    link: function(scope, element, $attributes) {
      element.on('click', function(event){
        event.stopPropagation();
        // In order to work with stopPropagation and two data way binding
        // if you don't use scope.$apply in my case the model is not updated in the view when I click on the element that has my directive
        scope.$apply(function () {
          scope.mySurvey.inEditionMode = true;
          console.log('inside the directive')
        });
      });
    }
  }
}

Now, you can easily use it in any button, link, div, etc. like so:

<button set-survey-in-edition-mode >Edit survey</button>

You can get the user's WindowsIdentity object under Windows Authentication by:

WindowsIdentity identity = HttpContext.Current.Request.LogonUserIdentity;

and then you can get the information about the user like identity.Name.

Please note you need to have HttpContext for these code.

position: absolute;
color: #ffffff;
font-weight: 500;
top: 0%;
left: 0%;
right: 0%;
text-align: center;

These examples are fine, I wanted to point out that you can achieve the same result using an Intent. The intent opens the Contacts app with the fields you provide already filled in.

It's up to the user to save the newly created contact.

You can read about it here: https://developer.android.com/training/contacts-provider/modify-data.html

Intent contactIntent = new Intent(ContactsContract.Intents.Insert.ACTION);
contactIntent.setType(ContactsContract.RawContacts.CONTENT_TYPE);

contactIntent
        .putExtra(ContactsContract.Intents.Insert.NAME, "Contact Name")
        .putExtra(ContactsContract.Intents.Insert.PHONE, "5555555555");

startActivityForResult(contactIntent, 1);

startActivityForResult() gives you the opportunity to see the result.

I've noticed the resultCode works on >5.0 devices,

but I have an older Samsung (<5) that always returns RESULT_CANCELLED (0).

Which I understand is the default return if an activity doesn't expect to return anything.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);

    if (requestCode == 1)
    {
        if (resultCode == Activity.RESULT_OK) {
            Toast.makeText(this, "Added Contact", Toast.LENGTH_SHORT).show();
        }
        if (resultCode == Activity.RESULT_CANCELED) {
            Toast.makeText(this, "Cancelled Added Contact", Toast.LENGTH_SHORT).show();
        }
    }
}

Instead of using position:relative in #icons, you could just take that away and maybe add a z-index or something so the picture won't get covered up. Hope this helps.

There are a handful of options:

• NPOI - Which is free and open source.
• Aspose - Is definitely not free but robust.
• Spreadsheet ML - Basically XML for creating spreadsheets.

Using the Interop will require that the Excel be installed on the machine from which it is running. In a server side solution, this will be awful. Instead, you should use a tool like the ones above that lets you build an Excel file without Excel being installed.

If the user does not have Excel but has a tool that will read Excel (like Open Office), then obviously they will be able to open it. Microsoft has a free Excel viewer available for those users that do not have Excel.

If you have cloned your project from git or somewhere then first, you should type npm install.

Here is how one can do it. I will give an example with joining so that it becomes super clear to someone.

$products = DB::table('products AS pr')
        ->leftJoin('product_families AS pf', 'pf.id', '=', 'pr.product_family_id')
        ->select('pr.id as id', 'pf.name as product_family_name', 'pf.id as product_family_id')
        ->orderBy('pr.id', 'desc')
        ->get();

Hope this helps.

The easiest way without installing msysgit is right click on the Git Bash shortcut icon ? Start in: ? "C:\Program Files (x86)".

Change the Start in entry and point out the Git Bash starting position. If you don't remove the --cd-to-home part from the Target box, the Start in change gets overridden.

Sort a two dimensional array based on one column
The first column is a date of format "yyyy.MM.dd HH:mm" and the second column is a String.

Since you say 2-D array, I assume "date of format ..." means a String. Here's code for sorting a 2-D array of String[][]:

import java.util.Arrays;
import java.util.Comparator;

public class Asdf {

    public static void main(final String[] args) {
        final String[][] data = new String[][] {
                new String[] { "2009.07.25 20:24", "Message A" },
                new String[] { "2009.07.25 20:17", "Message G" },
                new String[] { "2009.07.25 20:25", "Message B" },
                new String[] { "2009.07.25 20:30", "Message D" },
                new String[] { "2009.07.25 20:01", "Message F" },
                new String[] { "2009.07.25 21:08", "Message E" },
                new String[] { "2009.07.25 19:54", "Message R" } };

        Arrays.sort(data, new Comparator<String[]>() {
            @Override
            public int compare(final String[] entry1, final String[] entry2) {
                final String time1 = entry1[0];
                final String time2 = entry2[0];
                return time1.compareTo(time2);
            }
        });

        for (final String[] s : data) {
            System.out.println(s[0] + " " + s[1]);
        }
    }

}

Output:

2009.07.25 19:54 Message R
2009.07.25 20:01 Message F
2009.07.25 20:17 Message G
2009.07.25 20:24 Message A
2009.07.25 20:25 Message B
2009.07.25 20:30 Message D
2009.07.25 21:08 Message E

Simplest way in React Router 4 is to use

this.props.history.push('/new/url');

But to use this method, your existing component should have access to history object. We can get access by

1. If your component is linked to Route directly, then your component already has access to history object.

   eg:

   <Route path="/profile" component={ViewProfile}/>
   

   Here ViewProfile has access to history.

2. If not connected to Route directly.

   eg:

   <Route path="/users" render={() => <ViewUsers/>}
   

   Then we have to use withRouter, a heigher order fuction to warp the existing component.

   Inside ViewUsers component

   • import { withRouter } from 'react-router-dom';

   • export default withRouter(ViewUsers);

   That's it now, your ViewUsers component has access to history object.

UPDATE

2- in this scenario, pass all route props to your component, and then we can access this.props.history from the component even without a HOC

eg:

<Route path="/users" render={props => <ViewUsers {...props} />}

Yes, you can do this using introspection. Make a GraphQL query like (for type UserType)

{
   __type(name:"UserType") {
      fields {
         name
         description
      }  
   }
}

and you'll get a response like (actual field names will depend on your actual schema/type definition)

{
  "data": {
    "__type": {
      "fields": [
        {
          "name": "id",
          "description": ""
        },
        {
          "name": "username",
          "description": "Required. 150 characters or fewer. Letters, digits and @/./+/-/_ only."
        },
        {
          "name": "firstName",
          "description": ""
        },
        {
          "name": "lastName",
          "description": ""
        },
        {
         "name": "email",
          "description": ""
        },
        ( etc. etc. ...)
      ]
    }
  }
}

You can then read this list of fields in your client and dynamically build a second GraphQL query to get all of these fields.

This relies on you knowing the name of the type that you want to get the fields for -- if you don't know the type, you could get all the types and fields together using introspection like

{
  __schema {
    types {
      name
      fields {
        name
        description
      }
    }
  }
}

NOTE: this is the over-the-wire GraphQL data -- you're on your own to figure out how to read and write with your actual client. Your graphQL javascript library may already employ introspection in some capacity, for example the apollo codegen command uses introspection to generate types.

you will also need to have a asp:ScriptManager control on every page that you want to use ajax controls on. you should be able to just drag the scriptmanager over from your toolbox one the toolkit is installed following Zack's instructions.

If you can save the workbook then you have the option to use ADO and Jet/ACE to treat the workbook as a database, and execute SQL against the sheet.

The MSDN information on how to hit Excel using ADO can be found here.

First of all, you don't need to "clean up" strings and ints - they will be taken care of automatically by the garbage collector. The only thing that needs to be cleaned up in Dispose are unmanaged resources or managed recources that implement IDisposable.

However, assuming this is just a learning exercise, the recommended way to implement IDisposable is to add a "safety catch" to ensure that any resources aren't disposed of twice:

public void Dispose()
{
    Dispose(true);

    // Use SupressFinalize in case a subclass 
    // of this type implements a finalizer.
    GC.SuppressFinalize(this);   
}
protected virtual void Dispose(bool disposing)
{
    if (!_disposed)
    {
        if (disposing) 
        {
            // Clear all property values that maybe have been set
            // when the class was instantiated
            id = 0;
            name = String.Empty;
            pass = String.Empty;
        }

        // Indicate that the instance has been disposed.
        _disposed = true;   
    }
}

You can also use case then like this:

UPDATE  table
SET ID = case

when ID = 2555 then 111111259

when ID = 2724 then 111111261

when ID = 2021 then 111111263

when ID = 2017 then 111111264

else ID
end

Here is my extension method:

public static string ToFormattedString(this TimeSpan ts)
{
    const string separator = ", ";

    if (ts.TotalMilliseconds < 1) { return "No time"; }

    return string.Join(separator, new string[]
    {
        ts.Days > 0 ? ts.Days + (ts.Days > 1 ? " days" : " day") : null,
        ts.Hours > 0 ? ts.Hours + (ts.Hours > 1 ? " hours" : " hour") : null,
        ts.Minutes > 0 ? ts.Minutes + (ts.Minutes > 1 ? " minutes" : " minute") : null,
        ts.Seconds > 0 ? ts.Seconds + (ts.Seconds > 1 ? " seconds" : " second") : null,
        ts.Milliseconds > 0 ? ts.Milliseconds + (ts.Milliseconds > 1 ? " milliseconds" : " millisecond") : null,
    }.Where(t => t != null));
}

Example call:

string time = new TimeSpan(3, 14, 15, 0, 65).ToFormattedString();

Output:

3 days, 14 hours, 15 minutes, 65 milliseconds

I tried all the above no good. So I just add a padding individually:

 #button {

    font-size: 20px;
    color: white;
    background: crimson;
    border: 2px solid rgb(37, 34, 34);
    border-radius: 10px;
    padding-top: 10px;
    padding-bottom: 10px;
    padding-right: 10px;
    padding-left: 10px;
 }

May be with:

SELECT count(*) FROM `table` 
where 
    created_at>='2011-03-17 06:42:10' and created_at<='2011-03-17 07:42:50';

or use between:

SELECT count(*) FROM `table` 
where 
    created_at between '2011-03-17 06:42:10' and '2011-03-17 07:42:50';

You can change the datetime as per your need. May be use curdate() or now() to get the desired dates.

A lot of these answers only accept single-character separators, or don't deal with edge cases well (e.g. empty separators), so I thought I would provide a more definitive solution.

Here are two functions, gsplit and split, adapted from the code in the Scribunto MediaWiki extension, which is used on wikis like Wikipedia. The code is licenced under the GPL v2. I have changed the variable names and added comments to make the code a bit easier to understand, and I have also changed the code to use regular Lua string patterns instead of Scribunto's patterns for Unicode strings. The original code has test cases here.

-- gsplit: iterate over substrings in a string separated by a pattern
-- 
-- Parameters:
-- text (string)    - the string to iterate over
-- pattern (string) - the separator pattern
-- plain (boolean)  - if true (or truthy), pattern is interpreted as a plain
--                    string, not a Lua pattern
-- 
-- Returns: iterator
--
-- Usage:
-- for substr in gsplit(text, pattern, plain) do
--   doSomething(substr)
-- end
local function gsplit(text, pattern, plain)
  local splitStart, length = 1, #text
  return function ()
    if splitStart then
      local sepStart, sepEnd = string.find(text, pattern, splitStart, plain)
      local ret
      if not sepStart then
        ret = string.sub(text, splitStart)
        splitStart = nil
      elseif sepEnd < sepStart then
        -- Empty separator!
        ret = string.sub(text, splitStart, sepStart)
        if sepStart < length then
          splitStart = sepStart + 1
        else
          splitStart = nil
        end
      else
        ret = sepStart > splitStart and string.sub(text, splitStart, sepStart - 1) or ''
        splitStart = sepEnd + 1
      end
      return ret
    end
  end
end

-- split: split a string into substrings separated by a pattern.
-- 
-- Parameters:
-- text (string)    - the string to iterate over
-- pattern (string) - the separator pattern
-- plain (boolean)  - if true (or truthy), pattern is interpreted as a plain
--                    string, not a Lua pattern
-- 
-- Returns: table (a sequence table containing the substrings)
local function split(text, pattern, plain)
  local ret = {}
  for match in gsplit(text, pattern, plain) do
    table.insert(ret, match)
  end
  return ret
end

Some examples of the split function in use:

local function printSequence(t)

Even though it's not supposedly the correct way, setting the content type to text/html made IE deal with this correctly for me:

return Json(result, "text/html");

Works in all the version that F12 tools gives you in IE9.

jsPlumb is an option available that supports drag and drop, as seen by its numerous demos, including the Flowchart demo.

It is available in a free Community edition, and a paid Toolkit edition.

The Toolkit edition wraps the Community edition with a comprehensive data binding layer, as well as several UI widgets for building applications and integrations for popular libraries, and is commercially licensed.

Svg to png can be converted depending on conditions:

1. If svg is in format SVG (string) paths:

• create canvas
• create new Path2D() and set svg as parameter
• draw path on canvas
• create image and use canvas.toDataURL() as src.

example:

const canvas = document.createElement('canvas');
const ctx = canvas.getContext('2d');
let svgText = 'M10 10 h 80 v 80 h -80 Z';
let p = new Path2D('M10 10 h 80 v 80 h -80 Z');
ctx.stroke(p);
let url = canvas.toDataURL();
const img = new Image();
img.src = url;

Note that Path2D not supported in ie and partially supported in edge. Polyfill solves that: https://github.com/nilzona/path2d-polyfill

2. Create svg blob and draw on canvas using .drawImage():

• make canvas element
• make a svgBlob object from the svg xml
• make a url object from domUrl.createObjectURL(svgBlob);
• create an Image object and assign url to image src
• draw image into canvas
• get png data string from canvas: canvas.toDataURL();

Nice description: https://web.archive.org/web/20200125162931/http://ramblings.mcpher.com:80/Home/excelquirks/gassnips/svgtopng

Note that in ie you will get exception on stage of canvas.toDataURL(); It is because IE has too high security restriction and treats canvas as readonly after drawing image there. All other browsers restrict only if image is cross origin.

3. Use canvg JavaScript library. It is separate library but has useful functions.

Like:

ctx.drawSvg(rawSvg);
var dataURL = canvas.toDataURL();

First I would check if your MusicKarma project has Microsoft.Net.Compilers in its packages.config file. If not then you could remove everything to do with that NuGet package from your MusicKarma.csproj.

If you are using the Microsoft.Net.Compilers NuGet package then my guess is that the path is incorrect. Looking at the directory name in the error message I would guess that the MusicKarma solution file (.sln) is in the same directory as the MusicKarma.csproj. If so then the packages directory is probably wrong since by default the packages directory would be inside the solution directory. So I am assuming that your packages directory is:

C:\Users\Bryan\Documents\Visual Studio 2015\Projects\MusicKarma\packages

Whilst your MusicKarma.csproj file is looking for the props file in:

C:\Users\Bryan\Documents\Visual Studio 2015\Projects\packages\Microsoft.Net.Compilers.1.1.1\build

So if that is the case then you can fix the problem by editing the path in your MusicKarma.csproj file or by reinstalling the NuGet package.

You can open PowerShell and type "python". After Python has been imported, you can copy paste the source code from your favourite text-editor to run the code.

The window won't close.

One reason is that it is easy to create a set from map:

s := map[int]bool{5: true, 2: true}
_, ok := s[6] // check for existence
s[8] = true // add element 
delete(s, 2) // remove element

Union

s_union := map[int]bool{}
for k, _ := range s1{
    s_union[k] = true
}
for k, _ := range s2{
    s_union[k] = true
}

Intersection

s_intersection := map[int]bool{}
for k,_ := range s1 { 
  if s2[k] {
    s_intersection[k] = true
  }
}

It is not really that hard to implement all other set operations.

Iterate over an objects attributes in python:

class C:
    a = 5
    b = [1,2,3]
    def foobar():
        b = "hi"    

for attr, value in C.__dict__.iteritems():
    print "Attribute: " + str(attr or "")
    print "Value: " + str(value or "")

Prints:

python test.py
Attribute: a
Value: 5
Attribute: foobar
Value: <function foobar at 0x7fe74f8bfc08>
Attribute: __module__
Value: __main__
Attribute: b
Value: [1, 2, 3]
Attribute: __doc__
Value:

Type Ctrl+p then Ctrl+q. It will help you to turn interactive mode to daemon mode.

See https://docs.docker.com/v1.7/articles/basics/#running-an-interactive-shell.

# To detach the tty without exiting the shell,
# use the escape sequence Ctrl-p + Ctrl-q
# note: This will continue to exist in a stopped state once exited (see "docker ps -a")

If you mean an in-place sort (i.e. the list is updated):

people.Sort((x, y) => string.Compare(x.LastName, y.LastName));

If you mean a new list:

var newList = people.OrderBy(x=>x.LastName).ToList(); // ToList optional

This is for Mac OS X with the native installation of Apache HTTP and custom installation of MySQL.

The answer is based on @alec-gorge's excellent response, but since I had to google some specific changes to have it configured in my configuration, mostly Mac OS X-specific, I thought I'd add it here for the sake of completeness.

Enable PHP5 support for Apache HTTP

Make sure the PHP5 support is enabled in /etc/apache2/httpd.conf.

Edit the file with sudo vi /etc/apache2/httpd.conf (enter the password when asked) and uncomment (remove ; from the beginning of) the line to load the php5_module module.

LoadModule php5_module libexec/apache2/libphp5.so

Start Apache HTTP with sudo apachectl start (or restart if it's already started and needs to be restarted to re-read the configuration file).

Make sure that /var/log/apache2/error_log contains a line that tells you the php5_module is enabled - you should see PHP/5.3.15 (or similar).

[notice] Apache/2.2.22 (Unix) DAV/2 PHP/5.3.15 with Suhosin-Patch configured -- resuming normal operations

Looking up Socket file's name

When MySQL is up and running (with ./bin/mysqld_safe) there should be debug lines printed out to the console that tell you where you can find the log files. Note the hostname in the file name - localhost in my case - that may be different for your configuration.

The file that comes after Logging to is important. That's where MySQL logs its work.

130309 12:17:59 mysqld_safe Logging to '/Users/jacek/apps/mysql/data/localhost.err'.
130309 12:17:59 mysqld_safe Starting mysqld daemon with databases from /Users/jacek/apps/mysql/data

Open the localhost.err file (again, yours might be named differently), i.e. tail -1 /Users/jacek/apps/mysql/data/localhost.err to find out the socket file's name - it should be the last line.

$ tail -1 /Users/jacek/apps/mysql/data/localhost.err
Version: '5.5.27'  socket: '/tmp/mysql.sock'  port: 3306  MySQL Community Server (GPL)

Note the socket: part - that's the socket file you should use in php.ini.

There's another way (some say an easier way) to determine the location of the socket's file name by logging in to MySQL and running:

show variables like '%socket%';

Configuring PHP5 with MySQL support - /etc/php.ini

Speaking of php.ini...

In /etc directory there's /etc/php.ini.default file. Copy it to /etc/php.ini.

sudo cp /etc/php.ini.default /etc/php.ini

Open /etc/php.ini and look for mysql.default_socket.

sudo vi /etc/php.ini

The default of mysql.default_socket is /var/mysql/mysql.sock. You should change it to the value you have noted earlier - it was /tmp/mysql.sock in my case.

Replace the /etc/php.ini file to reflect the socket file's name:

mysql.default_socket = /tmp/mysql.sock
mysqli.default_socket = /tmp/mysql.sock

Final verification

Restart Apache HTTP.

sudo apachectl restart 

Check the logs if there are no error related to PHP5. No errors means you're done and PHP5 with MySQL should work fine. Congrats!

read last 3 characters from string [Initially asked question]

You can use string.Substring and give it the starting index and it will get the substring starting from given index till end.

myString.Substring(myString.Length-3)

Retrieves a substring from this instance. The substring starts at a specified character position. MSDN

Edit, for updated post

Remove last 3 characters from string [Updated question]

To remove the last three characters from the string you can use string.Substring(Int32, Int32) and give it the starting index 0 and end index three less than the string length. It will get the substring before last three characters.

myString = myString.Substring(0, myString.Length-3);

String.Substring Method (Int32, Int32)

Retrieves a substring from this instance. The substring starts at a specified character position and has a specified length.

You can also using String.Remove(Int32) method to remove the last three characters by passing start index as length - 3, it will remove from this point to end of string.

myString = myString.Remove(myString.Length-3)

String.Remove Method (Int32)

Returns a new string in which all the characters in the current instance, beginning at a specified position and continuing through the last position, have been deleted

It's probably worth noting that Powershell v3 and up, contains a cmdlet called Invoke-WebRequest that has some curl-ish capabilities. The New-WebServiceProxy and Invoke-RestMethod cmdlets are probably worth mentioning too.

I'm not sure they will fit your needs or not, but although I'm not a Windows guy, I have to say I find the object approach PS takes, a lot easier to work with than utilities such as curl, wget etc. They may be worth taking a look at

There was a bug in iOS 6, that causes line height to be ignored when font is set. See answer to NSParagraphStyle line spacing ignored and longer bug analysis at Radar: UITextView Ignores Minimum/Maximum Line Height in Attributed String.

I got one good solution. Here I have attached it as the image below. So try it. It may be helpful to you...!

I had a similar issue when working on Database restore operation on MS SQL Server 2012.

However, for my own scenario, I just needed to see the progress of the DATABASE RESTORE operation in the script window

All I had to do was add the STATS option to the script:

USE master;
GO

ALTER DATABASE mydb SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
GO
    
RESTORE DATABASE mydb
    FROM DISK = 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup\my_db_21-08-2020.bak'
    WITH REPLACE,
         STATS = 10,
         RESTART,
    MOVE 'my_db' TO 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\my_db.mdf',
    MOVE 'my_db_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\mydb_log.ldf'
GO
    
ALTER DATABASE mydb SET MULTI_USER;
GO

And then I switched to the Messages tab of the Script window to see the progress of the DATABASE RESTORE operation:

If you want to get more information after the DATABASE RESTORE operation you can use this command suggested by eythort:

SELECT command, percent_complete, start_time FROM sys.dm_exec_requests where command = 'RESTORE DATABASE'

That's all.

I hope this helps

findstr can do recursive searches (/S) and supports some variant of regex syntax (/R).

C:\>findstr /?
Searches for strings in files.

FINDSTR [/B] [/E] [/L] [/R] [/S] [/I] [/X] [/V] [/N] [/M] [/O] [/P] [/F:file]
        [/C:string] [/G:file] [/D:dir list] [/A:color attributes] [/OFF[LINE]]
        strings [[drive:][path]filename[ ...]]

  /B         Matches pattern if at the beginning of a line.
  /E         Matches pattern if at the end of a line.
  /L         Uses search strings literally.
  /R         Uses search strings as regular expressions.
  /S         Searches for matching files in the current directory and all
             subdirectories.
  /I         Specifies that the search is not to be case-sensitive.
  /X         Prints lines that match exactly.
  /V         Prints only lines that do not contain a match.
  /N         Prints the line number before each line that matches.
  /M         Prints only the filename if a file contains a match.
  /O         Prints character offset before each matching line.
  /P         Skip files with non-printable characters.
  /OFF[LINE] Do not skip files with offline attribute set.
  /A:attr    Specifies color attribute with two hex digits. See "color /?"
  /F:file    Reads file list from the specified file(/ stands for console).
  /C:string  Uses specified string as a literal search string.
  /G:file    Gets search strings from the specified file(/ stands for console).
  /D:dir     Search a semicolon delimited list of directories
  strings    Text to be searched for.
  [drive:][path]filename
             Specifies a file or files to search.

Use spaces to separate multiple search strings unless the argument is prefixed
with /C.  For example, 'FINDSTR "hello there" x.y' searches for "hello" or
"there" in file x.y.  'FINDSTR /C:"hello there" x.y' searches for
"hello there" in file x.y.

Regular expression quick reference:
  .        Wildcard: any character
  *        Repeat: zero or more occurrences of previous character or class
  ^        Line position: beginning of line
  $        Line position: end of line
  [class]  Character class: any one character in set
  [^class] Inverse class: any one character not in set
  [x-y]    Range: any characters within the specified range
  \x       Escape: literal use of metacharacter x
  \<xyz    Word position: beginning of word
  xyz\>    Word position: end of word

For full information on FINDSTR regular expressions refer to the online Command
Reference.

If you are looking for just the size of a file:

$ cat $file | wc -c
> 203233

$files = glob($_SERVER["DOCUMENT_ROOT"]."/myFolder/*");

Collections by themselves do not have a predefined order, therefore you must convert them to a java.util.List. Then you can use one form of java.util.Collections.sort

Collection< T > collection = ...;

List< T > list = new ArrayList< T >( collection );

Collections.sort( list );
 // or
Collections.sort( list, new Comparator< T >( ){...} );

// list now is sorted

How to determine that the partial object (Partial<T>) is equal to the original object (T) in typescript.

function compareTwoObjects<T>(original: T, partial: Partial<T>): boolean {
  return !Object.keys(partial).some((key) => partial[key] !== original[key]);
}

P.S. Initially I was planning to create a new question with an answer. But such a question already exists and marked as a duplicate.

From what I know, the correct syntax is:

function ChangeBackgroungImageOfTab(tabName, imagePrefix)
{
    document.getElementById(tabName).style.backgroundImage = "url('buttons/" + imagePrefix + ".png')";
}

So basically, getElementById(tabName).backgroundImage and split the string like:

"cssInHere('and" + javascriptOutHere + "/cssAgain')";

When I ran into trouble with this on Android Studio 3.1.4 the solution was to go into the app dropdown on my project, then Edit Configurations > Defaults > JAR Application where there is a JRE box on the initial Configuration tab. Setting that to my JRE path solved the problem for me.

Possibly something has changed in recent TensorFlow builds, because for me, running

sess = tf.Session()
sess.run(tf.local_variables_initializer())

before fitting any models seems to do the trick. Most older examples and comments seem to suggest tf.global_variables_initializer().

IRIs do not replace URIs, because only URIs (effectively, ASCII) are permissible in some contexts -- including HTTP.

Instead, you specify an IRI and it gets transformed into a URI when going out on the wire.

Maybe this might work:

Sh.Range("A1", Sh.Range("A" & Rows.Count).End(xlUp))

If all fails, as was the case with me, Uninstall GIT, reinstall. For some reason this fixes.

P.S.

1. I tried generating new Keys and Updating at SSH public keys
2. Also tried deleting all keys and tried to create a fresh key.
3. And NO, nothing wrong with my .gitconfig

You can use GetType - GetProperties - Linq Foreach:

obj.GetType().GetProperties().ToList().ForEach(p =>{
                                                        //p is each PropertyInfo
                                                        DoSomething(p);
                                                    });

try it out with the following code

function fun1()  
{  
   $this->db->select('count(DISTINCT(accessid))');  
   $this->db->from('accesslog');  
   $this->db->where('record =','123');  
   $query=$this->db->get();  
   return $query->num_rows();  
}

Answer: From php 5.3 and >, the var keyword is equivalent to public when declaring variables inside a class.

class myClass {
  var $x;
}

is the same as (for php 5.3 and >):

class myClass {
  public $x;
}

History: It was previously the norm for declaring variables in classes, though later became depreciated, but later (PHP 5.3) it became un-depreciated.

The code is okay but you are in the wrong directory. You must run these commands inside your rails project-directory.

The normal way to get there from scratch is:

$ rails new PROJECT_NAME
$ cd PROJECT_NAME
$ rails generate model ad \
    name:string \ 
    description:text \
    price:decimal \
    seller_id:integer \
    email:string img_url:string

Nothing of suggested above worked for me. My use case is having 4 custom ViewPagers in ScrollView. Top of them is measured based on aspect ratio and the rest just has layout_height=wrap_content. I've tried cybergen , Daniel López Lacalle solutions. None of them work fully for me.

My guess why cybergen doesn't work on page > 1 is because it calculates height of pager based on page 1, that is hidden if you scroll further.

Both cybergen and Daniel López Lacalle suggestions have weird behavior in my case: 2 of 3 are loaded ok and 1 randomly height is 0. Appears that onMeasure was called before children were populated. So I came up with a mixture of these 2 answers + my own fixes:

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    if (getLayoutParams().height == ViewGroup.LayoutParams.WRAP_CONTENT) {
        // find the first child view
        View view = getChildAt(0);
        if (view != null) {
            // measure the first child view with the specified measure spec
            view.measure(widthMeasureSpec, heightMeasureSpec);
            int h = view.getMeasuredHeight();
            setMeasuredDimension(getMeasuredWidth(), h);
            //do not recalculate height anymore
            getLayoutParams().height = h;
        }
    }
}

Idea is to let ViewPager calculate children's dimensions and save calculated height of first page in layout params of the ViewPager. Don't forget to set fragment's layout height to wrap_content otherwise you can get height=0. I've used this one:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" android:layout_width="match_parent"
    android:layout_height="wrap_content">
        <!-- Childs are populated in fragment -->
</LinearLayout>

Please note that this solution works great if all of your pages have same height. Otherwise you need to recalculate ViewPager height based on current child active. I don't need it, but if you suggest the solution I would be happy to update the answer.

The following query can be used to detemine tablespace and other params:

select df.tablespace_name "Tablespace",
       totalusedspace "Used MB",
       (df.totalspace - tu.totalusedspace) "Free MB",
       df.totalspace "Total MB",
       round(100 * ( (df.totalspace - tu.totalusedspace)/ df.totalspace)) "Pct. Free"
  from (select tablespace_name,
               round(sum(bytes) / 1048576) TotalSpace
          from dba_data_files 
         group by tablespace_name) df,
       (select round(sum(bytes)/(1024*1024)) totalusedspace,
               tablespace_name
          from dba_segments 
         group by tablespace_name) tu
 where df.tablespace_name = tu.tablespace_name 
   and df.totalspace <> 0;

Source: https://community.oracle.com/message/1832920

For your case if you want to know the partition name and it's size just run this query:

select owner,
       segment_name,
       partition_name,
       segment_type,
       bytes / 1024/1024 "MB" 
  from dba_segments 
 where owner = <owner_name>;

From go 1.13 onwards, if you had already configured your terminal with the git credentials and yet facing this issue, then you could try setting the GOPRIVATE environment variable. Setting this environment variable solved this issue for me.

export GOPRIVATE=github.com/{organizationName/userName of the package}/*  

echo date( "Y-m-d H:i:s", strtotime("2016-10-10 15:00:00")+(60*30) );//2016-10-10 15:30:00

or

echo date( "H:i:s", strtotime("15:00:00")+(60*30) ); // 15:30:00

or

echo date( "H:i:s", strtotime(date("H:i:s"))+(60*30) ); // 15:30:00

jsdom is too strict to do any real screen scraping sort of things, but beautifulsoup doesn't choke on bad markup.

node-soupselect is a port of python's beautifulsoup into nodejs, and it works beautifully

final Class B{

    static $staticVar;
    static function getA(){
        self::$staticVar = New A;
    }
}

the stucture of b is calld a singeton handler you can also do it in a

Class a{
    static $instance;
    static function getA(...){
        if(!isset(self::$staticVar)){
            self::$staticVar = New A(...);
        }
        return self::$staticVar;
    }
}

this is the singleton use $a = a::getA(...);

If both arrays are in the correct order; where each item corresponds to its associated member identifier then you can simply use.

var merge = _.merge(arr1, arr2);

Which is the short version of:

var merge = _.chain(arr1).zip(arr2).map(function(item) {
    return _.merge.apply(null, item);
}).value();

Or, if the data in the arrays is not in any particular order, you can look up the associated item by the member value.

var merge = _.map(arr1, function(item) {
    return _.merge(item, _.find(arr2, { 'member' : item.member }));
});

You can easily convert this to a mixin. See the example below:

_.mixin({_x000D_
  'mergeByKey' : function(arr1, arr2, key) {_x000D_
    var criteria = {};_x000D_
    criteria[key] = null;_x000D_
    return _.map(arr1, function(item) {_x000D_
      criteria[key] = item[key];_x000D_
      return _.merge(item, _.find(arr2, criteria));_x000D_
    });_x000D_
  }_x000D_
});_x000D_
_x000D_
var arr1 = [{_x000D_

}];_x000D_
_x000D_
var arr3 = _.mergeByKey(arr1, arr2, 'member');_x000D_

document.body.innerHTML = JSON.stringify(arr3, null, 4);

I used SSH.Net in a project a while ago and was very happy with it. It also comes with a good documentation with lots of samples on how to use it.

The original package website can be still found here, including the documentation (which currently isn't available on GitHub).

For your case the code would be something like this.

using (var client = new SshClient("hostnameOrIp", "username", "password"))
{
    client.Connect();
    client.RunCommand("etc/init.d/networking restart");
    client.Disconnect();
}

Here is what I did recently in PHP on one of my bigger systems:

1. User inputs newsletter text and selects the recipients (which generates a query to retrieve the email addresses for later).

2. Add the newsletter text and recipients query to a row in mysql table called *email_queue*

   • (The table email_queue has the columns "to" "subject" "body" "priority")

3. I created another script, which runs every minute as a cron job. It uses the SwiftMailer class. This script simply:

   • during business hours, sends all email with priority == 0

   • after hours, send other emails by priority

Depending on the hosts settings, I can now have it throttle using standard swiftmailers plugins like antiflood and throttle...

$mailer->registerPlugin(new Swift_Plugins_AntiFloodPlugin(50, 30));

and

$mailer->registerPlugin(new Swift_Plugins_ThrottlerPlugin( 100, Swift_Plugins_ThrottlerPlugin::MESSAGES_PER_MINUTE ));

etc, etc..

I have expanded it way beyond this pseudocode, with attachments, and many other configurable settings, but it works very well as long as your server is setup correctly to send email. (Probably wont work on shared hosting, but in theory it should...) Swiftmailer even has a setting

$message->setReturnPath

Which I now use to track bounces...

Happy Trails! (Happy Emails?)

Why such complications?

public static GregorianCalendar convertFromDMY(String dd_mm_yy) throws ParseException 
{
    SimpleDateFormat fmt = new SimpleDateFormat("dd-MMM-yyyy");
    Date date = fmt.parse(dd_mm_yy);
    GregorianCalendar cal = GregorianCalendar.getInstance();
    cal.setTime(date);
    return cal;
}

You will have to use cookie to store the value across page refresh. You can use any one of the many javascript based cookie libraries to simplify the cookie access, like this one

If you want to support only html5 then you can think of Storage api like localStorage/sessionStorage

Ex: using localStorage and cookies library

var mode = getStoredValue('myPageMode');

function buttonClick(mode) {
    mode = mode;
    storeValue('myPageMode', mode);
}

function storeValue(key, value) {
    if (localStorage) {
        localStorage.setItem(key, value);
    } else {
        $.cookies.set(key, value);
    }
}

function getStoredValue(key) {
    if (localStorage) {
        return localStorage.getItem(key);
    } else {
        return $.cookies.get(key);
    }
}

Accepted answer is not full. It doesn't work for events declared as {add; remove;}

Here is working code:

public static void ClearEventInvocations(this object obj, string eventName)
{
    var fi = obj.GetType().GetEventField(eventName);
    if (fi == null) return;
    fi.SetValue(obj, null);
}

private static FieldInfo GetEventField(this Type type, string eventName)
{
    FieldInfo field = null;
    while (type != null)
    {
        /* Find events defined as field */
        field = type.GetField(eventName, BindingFlags.Static | BindingFlags.Instance | BindingFlags.NonPublic);
        if (field != null && (field.FieldType == typeof(MulticastDelegate) || field.FieldType.IsSubclassOf(typeof(MulticastDelegate))))
            break;

        /* Find events defined as property { add; remove; } */
        field = type.GetField("EVENT_" + eventName.ToUpper(), BindingFlags.Static | BindingFlags.Instance | BindingFlags.NonPublic);
        if (field != null)
            break;
        type = type.BaseType;
    }
    return field;
}

A simpler solution:

Will the username and password be automatically SSL encrypted? Is the same true for GETs and POSTs

Yes, yes yes.

The entire communication (save for the DNS lookup if the IP for the hostname isn't already cached) is encrypted when SSL is in use.

You can use this syntax if some grads are attached with your variables.

y=torch.Tensor.cpu(x).detach().numpy()[:,:,:,-1]

This will work to both load and save a file into TXT from a HTML page with a save as choice

Try this

SELECT * FROM messages where id in (SELECT max(id) FROM messages GROUP BY from_id ) order by id desc

All answers above are correct and this is my take on this:

To differentiate between frame and bounds CONCEPTS developer should read:

1. relative to the superview (one parent view) it is contained within = FRAME
2. relative to its own coordinate system, determines its subview location = BOUNDS

"bounds" is confusing because it gives the impression that the coordinates are the position of the view for which it is set. But these are in relations and adjusted according to the frame constants.

Let's say you generate a bunch of views that are similar. You could set an OnClickListener for each view individually:

button1.setOnClickListener(new OnClickListener ... );
button2.setOnClickListener(new OnClickListener ... );
 ...

Then you have to create a unique onClick method for each view even if they do the similar things, like:

public void onClick(View v) {
    doAction(1); // 1 for button1, 2 for button2, etc.
}

This is because onClick has only one parameter, a View, and it has to get other information from instance variables or final local variables in enclosing scopes. What we really want is to get information from the views themselves.

Enter getTag/setTag:

button1.setTag(1);
button2.setTag(2);

Now we can use the same OnClickListener for every button:

listener = new OnClickListener() {
    @Override
    public void onClick(View v) {
        doAction(v.getTag());
    }
};

It's basically a way for views to have memories.

Swift 3 version (butt_img must be an Image Set into Assets.xcassets or Images.xcassets folder in Xcode):

btnTwo.setBackgroundImage(UIImage(named: "butt_img"), for: .normal)
btnTwo.setTitle("My title", for: .normal)

Anyway, if you want the image to be scaled to fill the button's size, you may add a UIImageView over it and assign it your image:

let img = UIImageView()
img.frame = btnTwo.frame
img.contentMode = .scaleAspectFill
img.clipsToBounds = true
img.image = UIImage(named: "butt_img")
btnTwo.addSubview(img)

Since the border is used just for visual appearance, you could put it into the ListBoxItem's ControlTemplate and modify the properties there. In the ItemTemplate, you could place only the StackPanel and the TextBlock. In this way, the code also remains clean, as in the appearance of the control will be controlled via the ControlTemplate and the data to be shown will be controlled via the DataTemplate.

Try to use target size you need insted of TRUNCATEONLY in DBCC:

DBCC SHRINKFILE ('Wxlog0', 1)

And check this to articles:

http://msdn.microsoft.com/en-us/library/ms189493(SQL.90).aspx

http://support.microsoft.com/kb/907511

Edit:

You can try to move allocated pages to the beginning of the log file first with

DBCC SHRINKFILE ('Wxlog0', NOTRUNCATE)

and after that

DBCC SHRINKFILE ('Wxlog0', 1)

1. In your app's theme/style, add the following lines:

   <item name="android:buttonBarNegativeButtonStyle">@style/NegativeButtonStyle</item>
   <item name="android:buttonBarPositiveButtonStyle">@style/PositiveButtonStyle</item>
   <item name="android:buttonBarNeutralButtonStyle">@style/NeutralButtonStyle</item>
   

2. Then add the following styles:

   <style name="NegativeButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
       <item name="android:textColor">@color/red</item>
   </style>
   
   <style name="PositiveButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
       <item name="android:textColor">@color/red</item>
   </style>
   
   <style name="NeutralButtonStyle" 
   parent="Widget.MaterialComponents.Button.TextButton.Dialog">
       <item name="android:textColor">#00f</item>
   </style>
   

Using this method makes it unneccessary to set the theme in the AlertDialog builder.

For end of line use:

git diff --ignore-space-at-eol

Instead of what are you using currently:

git diff -w (--ignore-all-space)

For start of line... you are out of luck if you want a built in solution.

However, if you don't mind getting your hands dirty there's a rather old patch floating out there somewhere that adds support for "--ignore-space-at-sol".

If the page you are on has a text or textarea input, click into this input (as if you want to enter text) then right-click and select 'Inspect element'.

You need:

record = record[:-1]

before the for loop.

This will set record to the current record list but without the last item. You may, depending on your needs, want to ensure the list isn't empty before doing this.

I had this problem and it was caused by the second level cache:

1. I persisted an entity using hibernate
2. Then I deleted the row created from a separate process that didn't interact with the second level cache
3. I persisted another entity with the same identifier (my identifier values are not auto-generated)

Hence, because the cache wasn't invalidated, hibernate assumed that it was dealing with a detached instance of the same entity.

Suggest the following simplification: capture return value from Workbooks.Add instead of subscripting Windows() afterward, as follows:

Set wkb = Workbooks.Add
wkb.SaveAs ...

wkb.Activate ' instead of Windows(expression).Activate

General Philosophy Advice:

Avoid use Excel's built-ins: ActiveWorkbook, ActiveSheet, and Selection: capture return values, and, favor qualified expressions instead.

Use the built-ins only once and only in outermost macros(subs) and capture at macro start, e.g.

Set wkb = ActiveWorkbook
Set wks = ActiveSheet
Set sel = Selection

During and within macros do not rely on these built-in names, instead capture return values, e.g.

Set wkb = Workbooks.Add 'instead of Workbooks.Add without return value capture
wkb.Activate 'instead of Activeworkbook.Activate

Also, try to use qualified expressions, e.g.

wkb.Sheets("Sheet3").Name = "foo" ' instead of Sheets("Sheet3").Name = "foo"

or

Set newWks = wkb.Sheets.Add
newWks.Name = "bar" 'instead of ActiveSheet.Name = "bar"

Use qualified expressions, e.g.

newWks.Name = "bar" 'instead of `xyz.Select` followed by Selection.Name = "bar" 

These methods will work better in general, give less confusing results, will be more robust when refactoring (e.g. moving lines of code around within and between methods) and, will work better across versions of Excel. Selection, for example, changes differently during macro execution from one version of Excel to another.

Also please note that you'll likely find that you don't need to .Activate nearly as much when using more qualified expressions. (This can mean the for the user the screen will flicker less.) Thus the whole line Windows(expression).Activate could simply be eliminated instead of even being replaced by wkb.Activate.

(Also note: I think the .Select statements you show are not contributing and can be omitted.)

(I think that Excel's macro recorder is responsible for promoting this more fragile style of programming using ActiveSheet, ActiveWorkbook, Selection, and Select so much; this style leaves a lot of room for improvement.)

varchar, Don't store separating characters you may want to format the phone numbers differently for different uses. so store (619) 123-4567 as 6191234567 I work with phone directory data and have found this to be the best practice.

I'd probably use a LEFT JOIN, which will return rows even if there's no match, and then you can select only the rows with no match by checking for NULLs.

So, something like:

SELECT V.*
FROM voter V LEFT JOIN elimination E ON V.id = E.voter_id
WHERE E.voter_id IS NULL

Whether that's more or less efficient than using a subquery depends on optimization, indexes, whether its possible to have more than one elimination per voter, etc.

This solution will work for all versions of Android. You can use reflection in Java to make it work for all Android devices:

Basically you should create a reflection wrapper to call the Android 2.2 setDisplayOrientation, instead of calling the specific method.

The method:

    protected void setDisplayOrientation(Camera camera, int angle){
    Method downPolymorphic;
    try
    {
        downPolymorphic = camera.getClass().getMethod("setDisplayOrientation", new Class[] { int.class });
        if (downPolymorphic != null)
            downPolymorphic.invoke(camera, new Object[] { angle });
    }
    catch (Exception e1)
    {
    }
}

And instead of using camera.setDisplayOrientation(x) use setDisplayOrientation(camera, x) :

    if (Integer.parseInt(Build.VERSION.SDK) >= 8)
        setDisplayOrientation(mCamera, 90);
    else
    {
        if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT)
        {
            p.set("orientation", "portrait");
            p.set("rotation", 90);
        }
        if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE)
        {
            p.set("orientation", "landscape");
            p.set("rotation", 90);
        }
    }   

What you put directly under src/main/java is in the default package, at the root of the classpath. It's the same for resources put under src/main/resources: they end up at the root of the classpath.

So the path of the resource is app-context.xml, not main/resources/app-context.xml.
