You need to do this:

OleDbConnection connection = new OleDbConnection(
    "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Inventar.accdb");
DataSet DS = new DataSet();
connection.Open();

string query = 
    @"SELECT tbl_Computer.*,  tbl_Besitzer.*
    FROM tbl_Computer 
    INNER JOIN tbl_Besitzer ON tbl_Computer.FK_Benutzer = tbl_Besitzer.ID 
    WHERE (((tbl_Besitzer.Vorname)='ma'))";
OleDbDataAdapter DBAdapter = new OleDbDataAdapter();
DBAdapter.SelectCommand = new OleDbCommand(query, connection); 
DBAdapter.Fill(DS);

By the way, what is this DataSet1? This should be "DataSet".

According to Apple documents for swift 4.1 you can use this struct so easily to create a 2D array:

Link: https://developer.apple.com/library/content/documentation/Swift/Conceptual/Swift_Programming_Language/Subscripts.html

Code sample:

struct Matrix {
    let rows: Int, columns: Int
    var grid: [Double]
    init(rows: Int, columns: Int) {
        self.rows = rows
        self.columns = columns
        grid = Array(repeating: 0.0, count: rows * columns)
    }
    func indexIsValid(row: Int, column: Int) -> Bool {
        return row >= 0 && row < rows && column >= 0 && column < columns
    }
    subscript(row: Int, column: Int) -> Double {
        get {
            assert(indexIsValid(row: row, column: column), "Index out of range")
            return grid[(row * columns) + column]
        }
        set {
            assert(indexIsValid(row: row, column: column), "Index out of range")
            grid[(row * columns) + column] = newValue
        }
    }
}

You're missing *s in the last two terms of your expression, so R is interpreting (e.g.) 0.207 (log(DIAM93))^2 as an attempt to call a function named 0.207 ...

For example:

> 1 + 2*(3)
[1] 7
> 1 + 2 (3)

Error: attempt to apply non-function

Your (unreproducible) expression should read:

censusdata_20$AGB93 = WD * exp(-1.239 + 1.980 * log (DIAM93) + 
                              0.207* (log(DIAM93))^2  -
                              0.0281*(log(DIAM93))^3)

Mathematica is the only computer system I know of that allows juxtaposition to be used for multiplication ...

You can also use printf to pipe the input to your script.

var=val
printf "yes\nno\nmaybe\n$var\n" | ./your_script.sh

Script snip below creates a pause sub that displayes the pause text in a string and waits for the Enter key. z can be anything. Great if multilple user intervention required pauses are needed. I just keep it in my standard script template.

Pause("Press Enter to continue")

Sub Pause(strPause)
     WScript.Echo (strPause)
     z = WScript.StdIn.Read(1)
End Sub

or am I missing something?

A View in Oracle and in other database systems is simply the representation of a SQL statement that is stored in memory so that it can easily be re-used. For example, if we frequently issue the following query

SELECT customerid, customername FROM customers WHERE countryid='US';

To create a view use the CREATE VIEW command as seen in this example

CREATE VIEW view_uscustomers
AS
SELECT customerid, customername FROM customers WHERE countryid='US';

This command creates a new view called view_uscustomers. Note that this command does not result in anything being actually stored in the database at all except for a data dictionary entry that defines this view. This means that every time you query this view, Oracle has to go out and execute the view and query the database data. We can query the view like this:

SELECT * FROM view_uscustomers WHERE customerid BETWEEN 100 AND 200;

And Oracle will transform the query into this:

SELECT * 
FROM (select customerid, customername from customers WHERE countryid='US') 
WHERE customerid BETWEEN 100 AND 200

Benefits of using Views

• Commonality of code being used. Since a view is based on one common set of SQL, this means that when it is called it’s less likely to require parsing.
• Security. Views have long been used to hide the tables that actually contain the data you are querying. Also, views can be used to restrict the columns that a given user has access to.
• Predicate pushing

You can find advanced topics in this article about "How to Create and Manage Views in Oracle."

you can do it on real device by run device in Debug mode

Click Debug->Simulate Location -> add .gpx file for your location during run time

We can do it by MySQL Workbench. Just execute this:

kill id;

Example:

kill 13412

That will remove it.

You can take the code above and go one step further by introducing a custom controller factory that injects the HandleErrorWithElmah attribute into every controller.

For more infomation check out my blog series on logging in MVC. The first article covers getting Elmah set up and running for MVC.

There is a link to downloadable code at the end of the article. Hope that helps.

Python opens files almost in the same way as in C:

• r+ Open for reading and writing. The stream is positioned at the beginning of the file.

• a+ Open for reading and appending (writing at end of file). The file is created if it does not exist. The initial file position for reading is at the beginning of the file, but output is appended to the end of the file (but in some Unix systems regardless of the current seek position).

I want to add to the answers above that it becomes a little more difficult if Jenkins authorization is enabled.

After enabling it I got an error message that anonymous user needs read permission.

I saw two possible solutions:

1: Changing my hook to:

curl --user name:passwd -s http://domain?token=whatevertokenuhave

2: setting project based authorization.

The former solutions has the disadvantage that I had to expose my passwd in the hook file. Unacceptable in my case.

The second works for me. In the global auth settings I had to enable Overall>Read for Anonymous user. In the project I wanted to trigger I had to enable Job>Build and Job>Read for Anonymous.

This is still not a perfect solution because now you can see the project in Jenkins without login. There might be an even better solution using the former approach with http login but I haven't figured it out.

You can't do it with pure html/javascript. This is because you have a seperate connection to the webserver to retrieve a separate file (the image) and a normal webserver will serve the file with content headers set so that the browser reading the content type will decide that the type can be handled internally.

The way to force the browser not to handle the file internally is to change the headers (content-disposition prefereably, or content-type) so the browser will not try to handle the file internally. You can either do this by writing a script on the webserver that dynamically sets the headers (i.e. download.php) or by configuring the webserver to return different headers for the file you want to download. You can do this on a per-directory basis on the webserver, which would allow you to get away without writing any php or javascript - simply have all your download images in that one location.

The configuration file is called applicationhost.config. It's stored here:

My Documents > IIS Express > config

usually, but not always, one of these paths will work

%userprofile%\documents\iisexpress\config\applicationhost.config
%userprofile%\my documents\iisexpress\config\applicationhost.config

Update for VS2019
If you're using Visual Studio 2019+ check this path:

$(solutionDir)\.vs\{projectName}\config\applicationhost.config

Update for VS2015 (credit: @Talon)
If you're using Visual Studio 2015-2017 check this path:

$(solutionDir)\.vs\config\applicationhost.config

In Visual Studio 2015+ you can also configure which applicationhost.config file is used by altering the <UseGlobalApplicationHostFile>true|false</UseGlobalApplicationHostFile> setting in the project file (eg: MyProject.csproj). (source: MSDN forum)

I recommend reading about string aggregation/concatentation in Oracle.

I know I'm late :) But this how i do it:

{
    try
    {
        var configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        var settings = configFile.AppSettings.Settings;
        if (settings[key] == null)
        {
            settings.Add(key, value);
        }
        else
        {
            settings[key].Value = value;
        }
        configFile.Save(ConfigurationSaveMode.Modified);
        ConfigurationManager.RefreshSection(configFile.AppSettings.SectionInformation.Name);
    }
    catch (ConfigurationErrorsException)
    {
        Console.WriteLine("Error writing app settings");

If you want to do it without using jquery or modenizer you can use the code below:

(function(){

     "use strict";

     //shim for String's trim function..
     function trim(string){
         return string.trim ? string.trim() : string.replace(/^\s+|\s+$/g, "");
     }

     //returns whether the given element has the given class name..
     function hasClassName(element, className){ 
         //refactoring of Prototype's function..
         var elClassName = element.className;
         if(!elClassName)
             return false;
         var regex = new RegExp("(^|\\s)" + className + "(\\s|$)");
         return regex.test(element.className);
     }

     function removeClassName(element, className){
         //refactoring of Prototype's function..
         var elClassName = element.className;
         if(!elClassName)
             return;
         element.className = elClassName.replace(
             new RegExp("(^|\\s+)" + className + "(\\s+|$)"), ' ');
     }

     function addClassName(element, className){
         var elClassName = element.className;
         if(elClassName)
             element.className += " " + className;
         else
             element.className = className;
     }

     //strings to make event attachment x-browser.. 
     var addEvent = document.addEventListener ?
            'addEventListener' : 'attachEvent';
     var eventPrefix = document.addEventListener ? '' : 'on';

     //the class which is added when the placeholder is being used..
     var placeHolderClassName = 'usingPlaceHolder';

     //allows the given textField to use it's placeholder attribute
     //as if it's functionality is supported natively..
     window.placeHolder = function(textField){

         //don't do anything if you get it for free..
         if('placeholder' in document.createElement('input'))
             return;

         //don't do anything if the place holder attribute is not
         //defined or is blank..
         var placeHolder = textField.getAttribute('placeholder');        
         if(!placeHolder)
             return;

         //if it's just the empty string do nothing..
         placeHolder = trim(placeHolder);
         if(placeHolder === '')
             return;

         //called on blur - sets the value to the place holder if it's empty..
         var onBlur = function(){
             if(textField.value !== '') //a space is a valid input..
                 return;
             textField.value = placeHolder;
             addClassName(textField, placeHolderClassName);
         };

         //the blur event..
         textField[addEvent](eventPrefix + 'blur', onBlur, false);

         //the focus event - removes the place holder if required..
         textField[addEvent](eventPrefix + 'focus', function(){
             if(hasClassName(textField, placeHolderClassName)){
                removeClassName(textField, placeHolderClassName);
                textField.value = "";
             }
         }, false);

         //the submit event on the form to which it's associated - if the
         //placeholder is attached set the value to be empty..
         var form = textField.form;
         if(form){
             form[addEvent](eventPrefix + 'submit', function(){
                 if(hasClassName(textField, placeHolderClassName))
                     textField.value = '';
            }, false);
         }

         onBlur(); //call the onBlur to set it initially..
    };

}());

For each text field you want to use it for you need to run placeHolder(HTMLInputElement), but I guess you can just change that to suit! Also, doing it this way, rather than just on load means that you can make it work for inputs which aren't in the DOM when the page loads.

Note, that this works by applying the class: usingPlaceHolder to the input element, so you can use this to style it (e.g. add the rule .usingPlaceHolder { color: #999; font-style: italic; } to make it look better).

If you wait until the page is loaded, and then set the button's display to none, that should work. Then you can make it visible at a later point.

I tried all these answers and, for some still unknown reason, none of them worked.

I had to "force feed" the GOPATH by setting the environment variable per every command that required it. For example:

sudo env GOPATH=$HOME/goWorkDirectory go build ...

Even glide was giving me the GOPATH not set error. Resolved it, again, by "force feeding": I tried all these answers and, for some still unknown reason, none of them worked.

This is now much more intuitive. The AVD interface now includes a sidebar with various functional shortcuts. The buttons circled in blue will rotate the device clockwise and counterclockwise on the screen.

Yes it is, none of the Visual Stdio editions have C mentioned, but it is included with the C++ compiler (you therefore need to look under C++). The main difference between using C and C++ is the naming system (i.e. using .c and not .cpp).

You do have to be careful not to create a C++ project and rename it to C though, that does not work.

Coding C from the command line:

Much like you can use gcc on Linux (or if you have MinGW installed) Visual Studio has a command to be used from command prompt (it must be the Visual Studio Developer Command Prompt though). As mentioned in the other answer you can use cl to compile your c file (make sure it is named .c)

Example:

cl myfile.c

Or to check all the accepted commands:

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community>cl
Microsoft (R) C/C++ Optimizing Compiler Version 19.16.27030.1 for x86
Copyright (C) Microsoft Corporation.  All rights reserved.

usage: cl [ option... ] filename... [ /link linkoption... ]

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community>

Coding C from the IDE:

Without doubt one of the best features of Visual Studio is the convenient IDE.

Although it takes more configuring, you get bonuses such as basic debugging before compiling (for example if you forget a ;)

To create a C project do the following:

Start a new project, go under C++ and select Empty Project, enter the Name of your project and the Location you want it to install to, then click Ok. Now wait for the project to be created.

Next under Solutions Explorer right click Source Files, select Add then New Item. You should see something like this:

Rename Source.cpp to include a .c extension (Source.c for example). Select the location you want to keep it in, I would recommend always keeping it within the project folder itself (in this case C:\Users\Simon\Desktop\Learn\My First C Code)

It should open up the .c file, ready to be modified. Visual Studio can now be used as normal, happy coding!

I think it's because there's differences in Application Context and Activity Context, as explained here: http://www.doubleencore.com/2013/06/context/

Which means that we can't show dialog using Application Context. That's it.

There is a pretty good list at linuxappfinder.com.

My personal preference for LaTeX on Linux has been the KDE-based editor Kile.

Adding to Brian Agnew's answer.

You can also do //div[@id='..' or @class='...] and you can have parenthesized expressions inside //div[@id='..' and (@class='a' or @class='b')].

Try to do something like this:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:bottom="-20dp" android:left="-20dp">
        <shape android:shape="rectangle">
            <solid android:color="@color/white" />

            <corners android:radius="20dp" />
        </shape>
    </item>
</layer-list>

It seems does not suitable to set different corner radius of rectangle. So you can use this hack.

You should note that div tag behaves like nothing and just let you to put something in it. It means that if you insert a paragraph with 100 lines of text within a div tag, it shows all the text but its height won't change to contain all the text.

So you have to use a CSS & HTML trick to handle this issue. This trick is very simple. you must use an empty div tag with class="clear" and then you will have to add this class to your CSS. Also note that your have #wrap in your CSS file but you don't have any tag with this id. In summary you have to change you code to something like below:

HTML Code:

    <!-- Change "id" from "container" to "wrap" -->
    <div id="wrap">    
        <div id="header">
        </div>

        <div id="navigation"> 
            <a href="/" class="navigation">home</a>
            <a href="about.php" class="navigation">about</a>
            <a href="fanlisting.php" class="navigation">fanlisting</a>
            <a href="reasons.php" class="navigation">100 reasons</a>
            <a href="letter.php" class="navigation">letter</a>
        </div>
        <div id="content" >
            <h1>Update Information</h1>
            <iframe name="frame" id="frame" src="http://website.org/update.php" allowtransparency="true" frameborder="0"></iframe>

            <!-- Add this line -->
            <div class="clear"></div>
        </div>
        <div id="footer">
        </div>

        <!-- Add this line -->
        <div class="clear"></div>
    </div>

And also add this line to your CSS file:

.clear{ display: block; clear: both;}

To recap (and for newbies). It's not that painful. Just add the protocol, then add the functions you need for detection.

In the view (class) that contains the UIScrolView, add the protocol, then added any the functions from here to your view (class).

// --------------------------------
// In the "h" file:
// --------------------------------
@interface myViewClass : UIViewController  <UIScrollViewDelegate> // <-- Adding the protocol here

// Scroll view
@property (nonatomic, retain) UIScrollView *myScrollView;
@property (nonatomic, assign) BOOL isScrolling;

// Protocol functions
- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView;
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView;


// --------------------------------
// In the "m" file:
// --------------------------------
@implementation BlockerViewController

- (void)viewDidLoad {
    CGRect scrollRect = self.view.frame; // Same size as this view
    self.myScrollView = [[UIScrollView alloc] initWithFrame:scrollRect];
    self.myScrollView.delegate = self;
    self.myScrollView.contentSize = CGSizeMake(scrollRect.size.width, scrollRect.size.height);
    self.myScrollView.contentInset = UIEdgeInsetsMake(0.0,22.0,0.0,22.0);
    // Allow dragging button to display outside the boundaries
    self.myScrollView.clipsToBounds = NO;
    // Prevent buttons from activating scroller:
    self.myScrollView.canCancelContentTouches = NO;
    self.myScrollView.delaysContentTouches = NO;
    [self.myScrollView setBackgroundColor:[UIColor darkGrayColor]];
    [self.view addSubview:self.myScrollView];

    // Add stuff to scrollview
    UIImage *myImage = [UIImage imageNamed:@"foo.png"];
    [self.myScrollView addSubview:myImage];
}

// Protocol functions
- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView {
    NSLog(@"start drag");
    _isScrolling = YES;
}

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView {
    NSLog(@"end decel");
    _isScrolling = NO;
}

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate {
    NSLog(@"end dragging");
    if (!decelerate) {
       _isScrolling = NO;
    }
}

// All of the available functions are here:
// https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIScrollViewDelegate_Protocol/Reference/UIScrollViewDelegate.html

If you are in a JEE7 environment, you must have a decent implementation of JAXRS hanging around, which would allow you to easily make asynchronous HTTP request using its client API.

This would looks like this:

public class Main {

    public static Future<Response> getAsyncHttp(final String url) {
        return ClientBuilder.newClient().target(url).request().async().get();
    }

    public static void main(String ...args) throws InterruptedException, ExecutionException {
        Future<Response> response = getAsyncHttp("http://www.nofrag.com");
        while (!response.isDone()) {
            System.out.println("Still waiting...");
            Thread.sleep(10);
        }
        System.out.println(response.get().readEntity(String.class));
    }
}

Of course, this is just using futures. If you are OK with using some more libraries, you could take a look at RxJava, the code would then look like:

public static void main(String... args) {
    final String url = "http://www.nofrag.com";
    rx.Observable.from(ClientBuilder.newClient().target(url).request().async().get(String.class), Schedulers
            .newThread())
            .subscribe(
                    next -> System.out.println(next),
                    error -> System.err.println(error),
                    () -> System.out.println("Stream ended.")
            );
    System.out.println("Async proof");
}

And last but not least, if you want to reuse your async call, you might want to take a look at Hystrix, which - in addition to a bazillion super cool other stuff - would allow you to write something like this:

For example:

public class AsyncGetCommand extends HystrixCommand<String> {

    private final String url;

    public AsyncGetCommand(final String url) {
        super(Setter.withGroupKey(HystrixCommandGroupKey.Factory.asKey("HTTP"))
                .andCommandPropertiesDefaults(HystrixCommandProperties.Setter()
                        .withExecutionIsolationThreadTimeoutInMilliseconds(5000)));
        this.url = url;
    }

    @Override
    protected String run() throws Exception {
        return ClientBuilder.newClient().target(url).request().get(String.class);
    }

 }

Calling this command would look like:

public static void main(String ...args) {
    new AsyncGetCommand("http://www.nofrag.com").observe().subscribe(
            next -> System.out.println(next),
            error -> System.err.println(error),
            () -> System.out.println("Stream ended.")
    );
    System.out.println("Async proof");

PS: I know the thread is old, but it felt wrong that no ones mentions the Rx/Hystrix way in the up-voted answers.

Try to wire below,

private void frmMyForm_Deactivate(object sender, EventArgs e)
    {
        // Raise your flag here.
    }

By wiring above event, it will tell you whenever the form is minimized, partially/totally hided by another form.

The datetime module is your friend:

import datetime
now = datetime.datetime.now()
print(now.year, now.month, now.day, now.hour, now.minute, now.second)
# 2015 5 6 8 53 40

You don't need separate variables, the attributes on the returned datetime object have all you need.

The correct regular expression formulation of the glob expression d* is ^d, which means match anything that starts with d.

    string input = "Message";
    string pattern = @"^d";
    Regex regex = new Regex(pattern, RegexOptions.IgnoreCase);

(The @ quoting is not necessary in this case, but good practice since many regexes use backslash escapes that need to be left alone, and it also indicates to the reader that this string is special).

cp is usually aliased like this

alias cp='cp -i'   # i.e. ask questions of overwriting

if you are sure that you want to do the overwrite then use this:

/bin/cp <arguments here> src dest

Try this Method

dataGridView1.DataSource = dt;
dt.Rows.Clear();

Create a file called MoveFiles.bat with the syntax

move c:\Sourcefoldernam\*.* e:\destinationFolder

then schedule a task to run that MoveFiles.bat every 10 hours.

Here is something I think will work for what you want, using a decorator.

class LogWrappedFunction(object):
    def __init__(self, function):
        self.function = function

    def logAndCall(self, *arguments, **namedArguments):
        print "Calling %s with arguments %s and named arguments %s" %\
                      (self.function.func_name, arguments, namedArguments)
        self.function.__call__(*arguments, **namedArguments)

def logwrap(function):
    return LogWrappedFunction(function).logAndCall

@logwrap
def doSomething(spam, eggs, foo, bar):
    print "Doing something totally awesome with %s and %s." % (spam, eggs)


doSomething("beans","rice", foo="wiggity", bar="wack")

Run it, it will yield the following output:

C:\scripts>python decoratorExample.py
Calling doSomething with arguments ('beans', 'rice') and named arguments {'foo':
 'wiggity', 'bar': 'wack'}
Doing something totally awesome with beans and rice.

Answer (Basic is advance!):

Error: 10060 Adding a timeout parameter to request solved the issue for me.

Example 1

import urllib
import urllib2
g = "http://www.google.com/"
read = urllib2.urlopen(g, timeout=20)

Example 2

A similar error also occurred while I was making a GET request. Again, passing a timeout parameter solved the 10060 Error.

response = requests.get(param_url, timeout=20)

Check whether you server is running or not.

I tried the code provided by Ranadheer Reddy (above) and it worked great. If you’re using a company computer that has a restricted server you may need to change the SMTP port to 25 and leave your username and password blank since they will auto fill by your admin.

Originally, I tried using EASendMail from the nugent package manager, only to realize that it’s a pay for version with 30-day trial. Don’t waist your time with it unless you plan on buying it. I noticed the program ran much faster using EASendMail, but for me, free trumped fast.

Just my 2 cents worth.

Like this?

public static void Test()
{
    using (var image = Image.FromFile(@"c:\logo.png"))
    using (var newImage = ScaleImage(image, 300, 400))
    {
        newImage.Save(@"c:\test.png", ImageFormat.Png);
    }
}

public static Image ScaleImage(Image image, int maxWidth, int maxHeight)
{
    var ratioX = (double)maxWidth / image.Width;
    var ratioY = (double)maxHeight / image.Height;
    var ratio = Math.Min(ratioX, ratioY);

    var newWidth = (int)(image.Width * ratio);
    var newHeight = (int)(image.Height * ratio);

    var newImage = new Bitmap(newWidth, newHeight);

    using (var graphics = Graphics.FromImage(newImage))
        graphics.DrawImage(image, 0, 0, newWidth, newHeight);

    return newImage;
}

This can be done by using the unbind function.

$('#myimage').unbind('click');

You can add multiple event handlers to the same object and event in jquery. This means adding a new one doesn't replace the old ones.

There are several strategies for changing event handlers, such as event namespaces. There are some pages about this in the online docs.

Look at this question (that's how I learned of unbind). There is some useful description of these strategies in the answers.

How to read bound hover callback functions in jquery

Because when the script executes the browser has not yet parsed the <body>, so it does not know that there is an element with the specified id.

Try this instead:

<html>
<head>
    <title></title>
    <script type="text/javascript">
        window.onload = (function () {
            var refButton = document.getElementById("btnButton");

            refButton.onclick = function() {
                alert('Dhoor shala!');
            };
        });
    </script>
    </head>
<body>
    <form id="form1">
    <div>
        <input id="btnButton" type="button" value="Click me"/>
    </div>
</form>
</body>
</html>

Note that you may as well use addEventListener instead of window.onload = ... to make that function only execute after the whole document has been parsed.

In z/OS while on version 10, use of CURRENT APPLICATION COMPATIBILITY is not allowed. You will have to resort to:

SELECT GETVARIABLE('SYSIBM.VERSION') AS VERSION,
       GETVARIABLE('SYSIBM.NEWFUN')  AS COMPATIBILITY
FROM SYSIBM.SYSDUMMY1;

Here is a link to all the variables available: https://www.ibm.com/support/knowledgecenter/SSEPEK_12.0.0/sqlref/src/tpc/db2z_refs2builtinsessionvars.html#db2z_refs2builtinsessionvars

It may not be obvious how to break a shell command into a sequence of arguments, especially in complex cases. shlex.split() can do the correct tokenization for args (I'm using Blender's example of the call):

import shlex
from subprocess import Popen, PIPE
command = shlex.split('swfdump /tmp/filename.swf/ -d')
process = Popen(command, stdout=PIPE, stderr=PIPE)
stdout, stderr = process.communicate()

Closing every window that was currently open followed by running the following command solved the issue for me:

taskkill /F /IM mmc.exe

edit php.ini file and increase memory_limit value.

memory_limit=1G

will solve this issue.

First, using a page-file when you have 4 GB of RAM is useless. Windows can't access more than 4GB (actually, less because of memory holes) so the page file is not used.

Second, the address space is split in 2, half for kernel, half for user mode. If you need more RAM for your applications use the /3GB option in boot.ini (make sure java.exe is marked as "large address aware" (google for more info).

Third, I think you can't allocate the full 2 GB of address space because java wastes some memory internally (for threads, JIT compiler, VM initialization, etc). Use the /3GB switch for more.

It can be due to psql not being in PATH

$ locate psql
/usr/lib/postgresql/9.6/bin/psql

Then create a link in /usr/bin

ln -s /usr/lib/postgresql/9.6/bin/psql /usr/bin/psql

Then try to execute psql it should work.

JSON has no functions as data types. You can only serialize strings, numbers, objects, arrays, and booleans (and null)

You could create your own toJson method, only passing the data that really has to be serialized:

Person.prototype.toJson = function() {
    return JSON.stringify({age: this.age});
};

Similar for deserializing:

Person.fromJson = function(json) {
    var data = JSON.parse(json); // Parsing the json string.
    return new Person(data.age);
};

The usage would be:

var serialize = p1.toJson();
var _p1 = Person.fromJson(serialize);
alert("Is old: " + _p1.isOld());

To reduce the amount of work, you could consider to store all the data that needs to be serialized in a special "data" property for each Person instance. For example:

function Person(age) {
    this.data = {
        age: age
    };
    this.isOld = function (){
        return this.data.age > 60 ? true : false;
    }
}

then serializing and deserializing is merely calling JSON.stringify(this.data) and setting the data of an instance would be instance.data = JSON.parse(json).

This would keep the toJson and fromJson methods simple but you'd have to adjust your other functions.

Side note:

You should add the isOld method to the prototype of the function:

Person.prototype.isOld = function() {}

Otherwise, every instance has it's own instance of that function which also increases memory.

The relational database uses a formal system of predicates to address data. The underlying physical implementation is of no substance and can vary to optimize for certain operations, but it must always assume the relational model. In layman's terms, that's just saying I know exactly how many values (attributes) each row (tuple) in my table (relation) has and now I want to exploit the fact accordingly, thoroughly and to it's extreme. That's the true nature of the beast. 

Since we're obviously the generation that has had a relational upbringing, if you look at NoSQL database models from the perspective of the relational model, again in layman's terms, the first obvious difference is that no assumptions about the number of values a row can contain is ever made. This is really oversimplifying the matter and does not cleanly apply to the intricacies of the physical models of every NoSQL database, but it's the pinnacle of the relational model and the first assumption we have to leave behind or, if you'd rather, the biggest leap we have to make.

We can agree to two things that are true for every DBMS: it can store any kind of data and has enough mathematical underpinnings to make it possible to manage the data in any way imaginable. The reality is that you'll never want to make the mistake of putting any of the two points to the test, but rather just stick with what the actual DBMS was really made for. In layman's terms: respect the beast within!

(Please note that I've avoided comparing the (obviously) well founded standards revolving around the relational model against the many flavors provided by NoSQL databases. If you'd like, consider NoSQL databases as an umbrella term for any DBMS that does not completely assume the relational model, in exclusion to everything else. The differences are too many, but that's the principal difference and the one I think would be of most use to you to understand the two.)

Late answer, I know but I too wanted this so I could log the SQL. The following is short and meets my needs.

The following produces SQL you can copy/paste in SSMS (it replaces the parameters with the values properly). You can add more types but this meets all I use in this case.

    private static void LogSQL(SqlCommand cmd)
        {
            string query = cmd.CommandText;

            foreach (SqlParameter prm in cmd.Parameters)
            {
                switch (prm.SqlDbType)
                {
                    case SqlDbType.Bit:
                        int boolToInt = (bool)prm.Value ? 1 : 0;
                        query = query.Replace(prm.ParameterName, string.Format("{0}", (bool)prm.Value ? 1 : 0));
                        break;
                    case SqlDbType.Int:
                        query = query.Replace(prm.ParameterName, string.Format("{0}", prm.Value));
                        break;
                    case SqlDbType.VarChar:
                        query = query.Replace(prm.ParameterName, string.Format("'{0}'", prm.Value));
                        break;
                    default:
                        query = query.Replace(prm.ParameterName, string.Format("'{0}'", prm.Value));
                        break;
                }
            }

            // the following is my how I write to my log - your use will vary
            logger.Debug("{0}", query);

            return;
        }

Now I can log the SQL just before I execute it:

LogSQL(queryCmd)
queryCmd.ExecuteNonQuery()

Are there best practices with regards to the organisation of packages in Java and what goes in them?

Not really no. There are lots of ideas, and lots opinions, but real "best practice" is to use your common sense!

(Please read No best Practices for a perspective on "best practices" and the people who promote them.)

However, there is one principal that probably has broad acceptance. Your package structure should reflect your application's (informal) module structure, and you should aim to minimize (or ideally entirely avoid) any cyclic dependencies between modules.

(Cyclic dependencies between classes in a package / module are just fine, but inter-package cycles tend to make it hard understand your application's architecture, and can be a barrier to code reuse. In particular, if you use Maven you will find that cyclic inter-package / inter-module dependencies mean that the whole interconnected mess has to be one Maven artifact.)

I should also add that there is one widely accepted best practice for package names. And that is that your package names should start with your organization's domain name in reverse order. If you follow this rule, you reduce the likelihood of problems caused by your (full) class names clashing with other peoples'.

I dont understand the frustrations. Why not just make a broadcastreceiver that filters for this intent:

android.provider.Telephony.MMS_RECEIVED

I checked a little further and you might need system level access to get this (rooted phone).

@ts-expect-error

TS 3.9 introduces a new magic comment. @ts-expect-error will:

• have same functionality as @ts-ignore
• trigger an error, if actually no compiler error has been suppressed (= indicates useless flag)

if (false) {
  // @ts-expect-error: Let's ignore a single compiler error like this unreachable code 
  console.log("hello"); // compiles
}

// If @ts-expect-error didn't suppress anything at all, we now get a nice warning 
let flag = true;
// ...
if (flag) {
  // @ts-expect-error
  // ^~~~~~~~~~~~~~~^ error: "Unused '@ts-expect-error' directive.(2578)"
  console.log("hello"); 
}

Alternatives

@ts-ignore and @ts-expect-error can be used for all sorts of compiler errors. For type issues (like in OP), I recommend one of the following alternatives due to narrower error suppression scope:

? Use any type

// type assertion for single expression
delete ($ as any).summernote.options.keyMap.pc.TAB;

// new variable assignment for multiple usages
const $$: any = $
delete $$.summernote.options.keyMap.pc.TAB;
delete $$.summernote.options.keyMap.mac.TAB;

? Augment JQueryStatic interface

// ./global.d.ts
interface JQueryStatic {
  summernote: any;
}

// ./main.ts
delete $.summernote.options.keyMap.pc.TAB; // works

In other cases, shorthand module declarations or module augmentations for modules with no/extendable types are handy utilities. A viable strategy is also to keep not migrated code in .js and use --allowJs with checkJs: false.

A compact little gem for Swift 2 / Xcode 7

@IBAction func SubmitAgeButton(sender: AnyObject) {

    let newAge = String(inputField.text!)        

if ((textField.text?.isEmpty) != false) {
        label.text = "Enter a number!"
    }
    else {
        label.text = "Oh, you're \(newAge)"

        return
    }

    }

package userinput;

import java.util.Scanner;

public class USERINPUT {

    public static void main(String[] args) {

        Scanner input = new Scanner(System.in);

        //allow user  input;
        System.out.println("How many numbers do you want to enter?");
        int num = input.nextInt();

        int array[] = new int[num];

        System.out.println("Enter the " + num + " numbers now.");

        for (int i = 0 ; i < array.length; i++ ) {
           array[i] = input.nextInt();
        }

        //you notice that now the elements have been stored in the array .. array[]

        System.out.println("These are the numbers you have entered.");
        printArray(array);

        input.close();

    }

    //this method prints the elements in an array......
    //if this case is true, then that's enough to prove to you that the user input has  //been stored in an array!!!!!!!
    public static void printArray(int arr[]){

        int n = arr.length;

        for (int i = 0; i < n; i++) {
            System.out.print(arr[i] + " ");
        }
    }

}

Or

-like '*'+$nameregex+'*'

if you would like to use wildcards.

You can effectively remove scientific notation in printing with this code:

options(scipen=999)

def props(cls):   
  return [i for i in cls.__dict__.keys() if i[:1] != '_']

properties = props(MyClass)

An instance variable would probably be the way to do what you want. You could make it static to persist the same value for the life of the program (or thread depending on your static memory model), or make it an ordinary instance var to control it over the life of an object instance. If that instance is a singleton, they'll behave the same way.

#if DEBUG
private /*static*/ bool s_bDoDebugOnlyCode = false;
#endif

void foo()
{   
  // ...
#if DEBUG
  if (s_bDoDebugOnlyCode)
  {
      // Code here gets executed only when compiled with the DEBUG constant, 
      // and when the person debugging manually sets the bool above to true.  
      // It then stays for the rest of the session until they set it to false.
  }
#endif
 // ...
}

Just to be complete, pragmas (preprocessor directives) are considered a bit of a kludge to use to control program flow. .NET has a built-in answer for half of this problem, using the "Conditional" attribute.

private /*static*/ bool doDebugOnlyCode = false; 
[Conditional("DEBUG")]
void foo()
{   
  // ...    
  if (doDebugOnlyCode)
  {
      // Code here gets executed only when compiled with the DEBUG constant, 
      // and when the person debugging manually sets the bool above to true.  
      // It then stays for the rest of the session until they set it to false.
  }    
  // ...
}

No pragmas, much cleaner. The downside is that Conditional can only be applied to methods, so you'll have to deal with a boolean variable that doesn't do anything in a release build. As the variable exists solely to be toggled from the VS execution host, and in a release build its value doesn't matter, it's pretty harmless.

You can use GNU awk:

$ cat hta
RewriteCond %{HTTP_HOST} !^www\.mysite\.net$
RewriteRule (.*) http://www.mysite.net/$1 [R=301,L]

$ gawk 'match($0, /.*(http.*?)\$/, m) { print m[1]; }' < hta
http://www.mysite.net/

For whatever reason the above would not work for me. This is what did:

if (tabControl.SelectedTab.Name == "tabName" )
{
     .. do stuff
}

where tabControl.SelectedTab.Name is the name attribute assigned to the page in the tabcontrol itself.

There is no need to write any code, just in cmd on the console you can write:

javac myFile.java
java ClassName > a.txt

The output data is stored in the a.txt file.

Other answers describe the purposes. Here are the characters each function will actually convert:

control = '\x00\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0A\x0B\x0C\x0D\x0E\x0F'
        + '\x10\x11\x12\x13\x14\X15\x16\x17\x18\x19\x1A\x1B\x1C\x1D\x1E\x1F'
                                                                    + '\x7F'
encodeURI         (control + ' "%<>[\\]^`{|}'                             )
encodeURIComponent(control + ' "%<>[\\]^`{|}' + '#$&,:;=?' + '+/@'        )
escape            (control + ' "%<>[\\]^`{|}' + '#$&,:;=?' +       "!'()~")

All characters above are converted to percent-hexadecimal codes. Space to %20, percent to %25, etc. The characters below pass through unchanged.

Here are the characters the functions will NOT convert:

pass_thru = '*-._0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'

encodeURI         (pass_thru + '#$&,:;=?' + '+/@' + "!'()~")
encodeURIComponent(pass_thru +                      "!'()~")
escape            (pass_thru +              '+/@'          )

I followed the above (never a bad idea to keep up to date with brew anyhow) and still had the same exact issue:

LAPTOP:folder Username$ php -v
dyld: Library not loaded: /usr/local/lib/libpng15.15.dylib
  Referenced from: /usr/local/bin/php
  Reason: image not found
Trace/BPT trap: 5

Then figured out a simpler way:

Search for your libpng version(s) on your box:

# Requires locate & updatedb for mac os x
# See Link [1] 
LAPTOP:folder Username$ locate libpng15.15.dylib
/Applications/GIMP.app/Contents/Resources/lib/libpng15.15.dylib
/usr/X11/lib/libpng15.15.dylib
/usr/local/Cellar/libpng/1.5.14/lib/libpng15.15.dylib

Make a symlink:

LAPTOP:folder Username$ ln -s /usr/local/Cellar/libpng/1.5.14/lib/libpng15.15.dylib /usr/local/lib/libpng15.15.dylib

Try again:

LAPTOP:folder Username$ php -v

Is there any reason this is not working for you?

If you have access to a linux box with mdbtools installed, you can use this Bash shell script (save as mdbconvert.sh):

#!/bin/bash

TABLES=$(mdb-tables -1 $1)

MUSER="root"
MPASS="yourpassword"
MDB="$2"

MYSQL=$(which mysql)

for t in $TABLES
do
    $MYSQL -u $MUSER -p$MPASS $MDB -e "DROP TABLE IF EXISTS $t"
done

mdb-schema $1 mysql | $MYSQL -u $MUSER -p$MPASS $MDB

for t in $TABLES
do
    mdb-export -D '%Y-%m-%d %H:%M:%S' -I mysql $1 $t | $MYSQL -u $MUSER -p$MPASS $MDB
done

To invoke it simply call it like this:

./mdbconvert.sh accessfile.mdb mysqldatabasename

It will import all tables and all data.

<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>

</script>
<style type="text/css">

<input type="submit" id="b2" value="B2"/>
<input type="submit" id="b3" value="B3" />

2) Check the user "root" whose Host value is localhost, and click the "Edit Privileges" icon.
3) In the "Change password" field, click "Password" and enter a new password.
4) Retype the password to confirm. Then click "Go" to apply the settings.

If you need to support other languages, instead of the typical A-Z, you can use the following:

preg_replace('/[^\p{L}\p{N} ]+/', '', $string);

• [^\p{L}\p{N} ] defines a negated (It will match a character that is not defined) character class of:
  • \p{L}: a letter from any language.
  • \p{N}: a numeric character in any script.
  • : a space character.
• + greedily matches the character class between 1 and unlimited times.

This will preserve letters and numbers from other languages and scripts as well as A-Z:

preg_replace('/[^\p{L}\p{N} ]+/', '', 'hello-world'); // helloworld
preg_replace('/[^\p{L}\p{N} ]+/', '', 'abc@~#123-+=öäå'); // abc123öäå
preg_replace('/[^\p{L}\p{N} ]+/', '', '????!@£$%^&*()'); // ????

^{Note: This is a very old, but still relevant question. I am answering purely to provide supplementary information that may be useful to future visitors.}

It depends which platform.

On GCC it's pretty trivial, see this post for more details.

On MSVC then you can use the StackWalker library that handles all of the underlying API calls needed for Windows.

You'll have to figure out the best way to integrate this functionality into your app, but the amount of code you need to write should be minimal.

To address specific scenario in question:

@Test
public void Test1() {

}

@Test (dependsOnMethods={"Test1"})
public void Test2() {

}

@Test (dependsOnMethods={"Test2"})
public void Test3() {

}

1. Close NetBeans.

2. Stop MySQL Server.

3. Update MySQL (if available)

4. Start MySQL Server.

5. Open NetBeans.

If still doesn't connect, download MySQL Connector/J and add mysql-connector-java-[version].jar to your classpath and also to your Webserver's lib directory. For instance, Tomcat lib path in XAMPP is
C:\xampp\tomcat\lib.
Then repeat the steps again.

In general, it's not going to have enough of an impact to worry about, particularly since it's an intranet app and not a general-use Internet app. In particular, since it's intranet, SEO isn't a concern, since your intranet shouldn't be accessible to search engines. (and if it is, it isn't an intranet app).

And any framework worth it's salt either already has a default way to do this, or is fairly easy to change how it deals with multi-word URL components, so I wouldn't worry about it too much.

That said, here's how I see the various options:

Hyphen

• The biggest danger for hyphens is that the same character (typically) is also used for subtraction and numerical negation (ie. minus or negative).
• Hyphens feel awkward in URL components. They seem to only make sense at the end of a URL to separate words in the title of an article. Or, for example, the title of a Stack Overflow question that is added to the end of a URL for SEO and user-clarity purposes.

Underscore

• Again, they feel wrong in URL components. They break up the flow (and beauty/simplicity) of a URL, since they essentially add a big, heavy apparent space in the middle of a clean, flowing URL.
• They tend to blend in with underlines. If you expect your users to copy-paste your URLs into MS Word or other similar text-editing programs, or anywhere else that might pick up on a URL and style it with an underline (like links traditionally are), then you might want to avoid underscores as word separators. Particularly when printed, an underlined URL with underscores tends to look like it has spaces in it instead of underscores.

CamelCase

• By far my favorite, since it makes the URLs seem to flow better and doesn't have any of the faults that the previous two options do.
• Can be slightly harder to read for people that have a hard time differentiating upper-case from lower-case, but this shouldn't be much of an issue in a URL, because most "words" should be URL components and separated by a / anyways. If you find that you have a URL component that is more than 2 "words" long, you should probably try to find a better name for that concept.
• It does have a possible issue with case sensitivity, but most platforms can be adjusted to be either case-sensitive or case-insensitive. Any it's only really an issue for 2 cases: a.) humans typing the URL in, and b.) Programmers (since we are not human) typing the URL in. Typos are always a problem, regardless of case sensitivity, so this is no different that all one case.

My simple, simple, simple approach! =D

Code

string_to_test = "The criminals stole $1,000,000 in jewels."
chars_to_check = ["$", ",", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9"]
for char in chars_to_check:
    if char in string_to_test:
        print("Char \"" + char + "\" detected!")

Output

Char "$" detected!
Char "," detected!
Char "0" detected!
Char "1" detected!

Thanks!

I solved this problem by disconnecting my VPN (My OS is ubuntu-16.04).

If we use the below annotations and remove the "@XmlElement" annotation, code should work properly and resultant XML would have the element names similar to the class member.

@XmlRootElement(name="<RootElementName>")
@XmlAccessorType(XmlAccessType.FIELD)

In case use of "@XmlElement" is really required, please define it as field level and code should work perfectly. Don't define the annotation on the top of getter method.

Had tried both the above approaches mentioned and got to fix the issue.

I have not used Sequelize, but after reading its documentation, it's obvious that you are instantiating a new object, that's why Sequelize inserts a new record into the db.

First you need to search for that record, fetch it and only after that change its properties and update it, for example:

Project.find({ where: { title: 'aProject' } })
  .on('success', function (project) {
    // Check if record exists in db
    if (project) {
      project.update({
        title: 'a very different title now'
      })
      .success(function () {})
    }
  })

 sSource = StringUtils.replace(sSource, "\\/", "/")

If you're trying to put a button in a rounded-rectangle border, you should check out msdn's example. I found this by googling for images of the problem (instead of text). Their bulky outer rectangle is (thankfully) easy to remove.

Note that you will have to redefine the button's behavior (since you've changed the ControlTemplate). That is, you will need to define the button's behavior when clicked using a Trigger tag (Property="IsPressed" Value="true") in the ControlTemplate.Triggers tag. Hope this saves someone else the time I lost :)

I might be a little late to the party but this is what I've created to convert a singular object to FormData.

function formData(formData, filesIgnore = []) {
  let data = new FormData();

  let files = filesIgnore;

  Object.entries(formData).forEach(([key, value]) => {
    if (typeof value === 'object' && !files.includes(key)) {
      data.append(key, JSON.stringify(value) || null);
    } else if (files.includes(key)) {
      data.append(key, value[0] || null);
    } else {
      data.append(key, value || null);
    }
  })

  return data;
}

How does it work? It will convert and return all properties expect File objects that you've set in the ignore list (2nd argument. If anyone could tell me a better way to determine this that would help!) into a json string using JSON.stringify. Then on your server you'll just need to convert it back into a JSON object.

Example:

let form = {
  first_name: 'John',
  last_name: 'Doe',
  details: {
    phone_number: 1234 5678 910,
    address: '123 Some Street',
  },
  profile_picture: [object FileList] // set by your form file input. Currently only support 1 file per property.
}

function submit() {
  let data = formData(form, ['profile_picture']);

  axios.post('/url', data).then(res => {
    console.log('object uploaded');
  })
}

I am still kinda new to Http requests and JavaScript so any feedback would be highly appreciated!

there is a bit other case - data is sent from client to server. when you are using controller method and model is huge :

    [HttpPost]
    public ActionResult AddOrUpdateConsumerFile(FileMetaDataModelView inputModel)
    {
        if (inputModel == null) return null;
     ....
    }

system throws exception like this "Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property. Parameter name: input"

Only changing Web.config settings is not enough to help in this case. You could additionally override mvc json serializer for supporting huge data model sizes or manually deserialize model from Request. Your controller method becomes:

   [HttpPost]
    public ActionResult AddOrUpdateConsumerFile()
    {
        FileMetaDataModelView inputModel = RequestManager.GetModelFromJsonRequest<FileMetaDataModelView>(HttpContext.Request);
        if (inputModel == null) return null;
        ......
    }

   public static T GetModelFromJsonRequest<T>(HttpRequestBase request)
    {
        string result = "";
        using (Stream req = request.InputStream)
        {
            req.Seek(0, System.IO.SeekOrigin.Begin);
            result = new StreamReader(req).ReadToEnd();
        }
        return JsonConvert.DeserializeObject<T>(result);
    }

Though all good answers, unfortunately none of them worked for me. So I had to write something old school. ( I was on a bare minimal Linux OS )

$ date -d @$( echo $(( $(date +%s)-$((60*60*24)) )) )

You can combine this with date's usual formatting. Eg.

$ date -d @$( echo $(( $(date +%s)-$((60*60*24)) )) ) +%Y-%m-%d

Explanation : Take date input in terms of epoc seconds ( the -d option ), from which you would have subtracted one day equivalent seconds. This will give the date precisely one day back.

Assuming you already have the blank database created, you can also restore a database from the command line like this:

mysql databasename < backup.sql

You can include JQuery using any of the following:

• Link Using jQuery with a CDN

<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>

• Download Jquery From Here and include in your project

• http://jquery.com/download/
• https://code.jquery.com/

• Download latest version using this link

• http://code.jquery.com/jquery-latest.min.js (never use this link on production server)

Your code placement can look something like this

• Your Jquery should be included before using it any where else it will throw an error

```

<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
<script>
$(document).ready(function(){
    $('input[type=radio]').change(function() {

    $('input[type=radio]').each(function(index) {
        $(this).closest('tr').removeClass('selected');
    });

        $(this).closest('tr').addClass('selected');
    });
});
</script>

```

One method I am fond of is based on the observer pattern. I define a signal class which my thread uses to emit exceptions to listeners. It can also be used to return values from threads. Example:

import threading

class Signal:
    def __init__(self):
        self._subscribers = list()

    def emit(self, *args, **kwargs):
        for func in self._subscribers:
            func(*args, **kwargs)

    def connect(self, func):
        self._subscribers.append(func)

    def disconnect(self, func):
        try:
            self._subscribers.remove(func)
        except ValueError:
            raise ValueError('Function {0} not removed from {1}'.format(func, self))


class WorkerThread(threading.Thread):

    def __init__(self, *args, **kwargs):
        super(WorkerThread, self).__init__(*args, **kwargs)
        self.Exception = Signal()
        self.Result = Signal()

    def run(self):
        if self._Thread__target is not None:
            try:
                self._return_value = self._Thread__target(*self._Thread__args, **self._Thread__kwargs)
            except Exception as e:
                self.Exception.emit(e)
            else:
                self.Result.emit(self._return_value)

if __name__ == '__main__':
    import time

    def handle_exception(exc):
        print exc.message

    def handle_result(res):
        print res

    def a():
        time.sleep(1)
        raise IOError('a failed')

    def b():
        time.sleep(2)
        return 'b returns'

    t = WorkerThread(target=a)
    t2 = WorkerThread(target=b)
    t.Exception.connect(handle_exception)
    t2.Result.connect(handle_result)
    t.start()
    t2.start()

    print 'Threads started'

    t.join()
    t2.join()
    print 'Done'

I do not have enough experience of working with threads to claim that this is a completely safe method. But it has worked for me and I like the flexibility.

You can use lambda to pass a reference to the window object as argument to close_window function:

button = Button (frame, text="Good-bye.", command = lambda: close_window(window))

This works because the command attribute is expecting a callable, or callable like object. A lambda is a callable, but in this case it is essentially the result of calling a given function with set parameters.

In essence, you're calling the lambda wrapper of the function which has no args, not the function itself.

I had this issue and my problem was that I was calling my method with any() instead of anyInt(). So I had:

doAnswer(...).with(myMockObject).thisFuncTakesAnInt(any())

and I had to change it to:

doAnswer(...).with(myMockObject).thisFuncTakesAnInt(anyInt())

I have no idea why that produced a NullPointerException. Maybe this will help the next poor soul.

Others have already covered the difference between Dispose and Finalize (btw the Finalize method is still called a destructor in the language specification), so I'll just add a little about the scenarios where the Finalize method comes in handy.

Some types encapsulate disposable resources in a manner where it is easy to use and dispose of them in a single action. The general usage is often like this: open, read or write, close (Dispose). It fits very well with the using construct.

Others are a bit more difficult. WaitEventHandles for instances are not used like this as they are used to signal from one thread to another. The question then becomes who should call Dispose on these? As a safeguard types like these implement a Finalize method, which makes sure resources are disposed when the instance is no longer referenced by the application.

Implement onFocusChange of setOnFocusChangeListener and there's a boolean parameter for hasFocus. When this is false, you've lost focus to another control.

 EditText txtEdit = (EditText) findViewById(R.id.edittxt);

 txtEdit.setOnFocusChangeListener(new OnFocusChangeListener() {          
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (!hasFocus) {
               // code to execute when EditText loses focus
            }
        }
    });

$user_ip=$_SERVER['REMOTE_ADDR'];

$check_ip = mysql_query("select userip from pageview where page='yourpage'  and userip='$user_ip'");
if(mysql_num_rows($check_ip)>=1)
{

}
else
{
  $insertview = mysql_query("insert into pageview values('','yourpage','$user_ip')");

  $updateview = mysql_query("update totalview set totalvisit = totalvisit+1 where page='yourpage' ");
}

I had the same issue when trying to install a package for Node.js. After some extensive googeling I found this walktrough: https://github.com/TooTallNate/node-gyp/wiki/Visual-Studio-2010-Setup

When I had followed these steps I could use "npm install" without any issues.

As per the Font Awesome Documentation:

<ul class="fa-ul">
  <li><i class="fa-li fa fa-check"></i>Barbabella</li>
  <li><i class="fa-li fa fa-check"></i>Barbaletta</li>
  <li><i class="fa-li fa fa-check"></i>Barbalala</li>
</ul>

Or, using Jade:

ul.fa-ul
  li
    i.fa-li.fa.fa-check
    | Barbabella
  li
    i.fa-li.fa.fa-check
    | Barbaletta
  li
    i.fa-li.fa.fa-check
    | Barbalala

The solution work for many cases and cross browser:

Code

var getTotal = function(collection) {

    var length = collection['length'];
    var isArrayObject =  typeof length == 'number' && length >= 0 && length <= Math.pow(2,53) - 1; // Number.MAX_SAFE_INTEGER

    if(isArrayObject) {
        return collection['length'];
    }

    i= 0;
    for(var key in collection) {
        if (collection.hasOwnProperty(key)) {
            i++;
        }
    }

    return i;
};

Data Examples:

// case 1
var a = new Object();
a["firstname"] = "Gareth";
a["lastname"] = "Simpson";
a["age"] = 21;

//case 2
var b = [1,2,3];

// case 3
var c = {};
c[0] = 1;
c.two = 2;

Usage

getLength(a); // 3
getLength(b); // 3
getLength(c); // 2

There is a library that try to do what you say.

Reads the DOM, from the html and render it to a canvas, fail on some, but in general works.

In Oracle, (+) denotes the "optional" table in the JOIN. So in your query,

SELECT a.id, b.id, a.col_2, b.col_2, ...
FROM a,b
WHERE a.id=b.id(+)

it's a LEFT OUTER JOIN of table 'b' to table 'a'. It will return all data of table 'a' without losing its data when the other side (optional table 'b') has no data.

The modern standard syntax for the same query would be

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
LEFT JOIN b ON a.id=b.id

or with a shorthand for a.id=b.id (not supported by all databases):

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
LEFT JOIN b USING(id)

If you remove (+) then it will be normal inner join query

Older syntax, in both Oracle and other databases:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a,b
WHERE a.id=b.id

More modern syntax:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
INNER JOIN b ON a.id=b.id

Or simply:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
JOIN b ON a.id=b.id

It will only return all data where both 'a' & 'b' tables 'id' value is same, means common part.

If you want to make your query a Right Join

This is just the same as a LEFT JOIN, but switches which table is optional.

Old Oracle syntax:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a,b
WHERE a.id(+)=b.id

Modern standard syntax:

SELECT  a.id, b.id, a.col_2, b.col_2, ...
FROM a
RIGHT JOIN b ON a.id=b.id

Microsoft provides a walkthrough for creating a Windows Explorer style interface in C#.

There are also several examples on Code Project and other sites. Immediate examples are Explorer Tree, My Explorer, File Browser and Advanced File Explorer but there are others. Explorer Tree seems to look the best from the brief glance I took.

I used the search term windows explorer tree view C# in Google to find these links.

Data flow diagram shows the flow of data between the different entities and datastores in a system while a flow chart shows the steps involved to carried out a task. In a sense, data flow diagram provides a very high level view of the system, while a flow chart is a lower level view (basically showing the algorithm).

Whether you use data flow diagram or flow charts depends on figuring out what is it that you are trying to show.

For those who are absolutely sure their relative path is correct, my problem was that my files did not have the .rb extension! (Even though I used RubyMine to create the files and selected that they were Ruby files on creation.)

Double check the file extensions on your file!

Edit: Sometimes you want to use webpack simply as a module bundler for a simple web project - to keep your own code organized. The following solution is for those who just want an external library to work as expected inside their modules - without using a lot of time diving into webpack setups. (Edited after -1)

Quick and simple (es6) solution if you’re still struggling or want to avoid externals config / additional webpack plugin config:

<script src="cdn/jquery.js"></script>
<script src="cdn/underscore.js"></script>
<script src="etc.js"></script>
<script src="bundle.js"></script>

inside a module:

const { jQuery: $, Underscore: _, etc } = window;

Use this code where str is your JSON string:

NSError *err = nil;
NSArray *arr = 
 [NSJSONSerialization JSONObjectWithData:[str dataUsingEncoding:NSUTF8StringEncoding] 
                                 options:NSJSONReadingMutableContainers 
                                   error:&err];
// access the dictionaries
NSMutableDictionary *dict = arr[0];
for (NSMutableDictionary *dictionary in arr) {
  // do something using dictionary
}

Karma or Protractor

Karma is a JavaScript test-runner built with Node.js and meant for unit testing.

The Protractor is for end-to-end testing and uses Selenium Web Driver to drive tests.

Both have been made by the Angular team. You can use any assertion-library you want with either.

Screencast: Karma Getting started

related:

• Should I be using Protractor or Karma for my end-to-end testing?
• Can Protractor and Karma be used together?

pros:

  • Extend it to wrap other test-frameworks (Jasmine, Mocha, QUnit built-in)
  • Your own assertions/refutes
  • Reporters
  • Browser Launchers
• Plugin for WebStorm
• Supported by Netbeans IDE

Cons:

• Does not support NodeJS (i.e. backend) testing
• No plugin for Eclipse (yet)
• No history of previous test results

mocha.js

I'm totally unqualified to comment on mocha.js's features, strengths, and weaknesses, but it was just recommended to me by someone I trust in the JS community.

List of features, as reported by its website:

• browser support
• simple async support, including promises
• test coverage reporting
• string diff support
• javascript # API for running tests
• proper exit status for CI support etc
• auto-detects and disables coloring for non-ttys
• maps uncaught exceptions to the correct test case
• async test timeout support
• test-specific timeouts
• growl notification support
• reports test durations
• highlights slow tests
• file watcher support
• global variable leak detection
• optionally run tests that match a regexp
• auto-exit to prevent "hanging" with an active loop
• easily meta-generate suites & test-cases
• mocha.opts file support
• clickable suite titles to filter test execution
• node debugger support
• detects multiple calls to done()
• use any assertion library you want
• extensible reporting, bundled with 9+ reporters
• extensible test DSLs or "interfaces"
• before, after, before each, after each hook
• arbitrary transpiler support (coffee-script etc)
• TextMate bundle

yolpo

This no longer exists, redirects to sequential.js instead

Yolpo is a tool to visualize the execution of javascript. Javascript API developers are encouraged to write their use cases to show and tell their API. Such use cases forms the basis of regression tests.

AVA

Futuristic test runner with built-in support for ES2015. Even though JavaScript is single-threaded, IO in Node.js can happen in parallel due to its async nature. AVA takes advantage of this and runs your tests concurrently, which is especially beneficial for IO heavy tests. In addition, test files are run in parallel as separate processes, giving you even better performance and an isolated environment for each test file.

• Minimal and fast
• Simple test syntax
• Runs tests concurrently
• Enforces writing atomic tests
• No implicit globals
• Isolated environment for each test file
• Write your tests in ES2015
• Promise support
• Generator function support
• Async function support
• Observable support
• Enhanced asserts
• Optional TAP o utput
• Clean stack traces

Buster.js

A JavaScript test-runner built with Node.js. Very modular and flexible. It comes with its own assertion library, but you can add your own if you like. The assertions library is decoupled, so you can also use it with other test-runners. Instead of using assert(!...) or expect(...).not..., it uses refute(...) which is a nice twist imho.

A browser JavaScript testing toolkit. It does browser testing with browser automation (think JsTestDriver), QUnit style static HTML page testing, testing in headless browsers (PhantomJS, jsdom, ...), and more. Take a look at the overview!

A Node.js testing toolkit. You get the same test case library, assertion library, etc. This is also great for hybrid browser and Node.js code. Write your test case with Buster.JS and run it both in Node.js and in a real browser.

Screencast: Buster.js Getting started (2:45)

pros:

• Uses node.js, so compatible with Win/OS X/Linux
• Run tests from a browser or headless with PhantomJS (soon)
• Run on multiple clients at once
• Supports NodeJS testing
• Don't need to run server/clients on development computer (no need for IE)
• Run tests from a command line (can be integrated into ant/maven)
• Write tests xUnit or BDD style
• Supports multiple JavaScript test frameworks
• Defer tests instead of commenting them out
• SinonJS built-in
• Auto-run tests on save
• Proxies requests cross-domain
• Possible to customize:
  • Extend it to wrap other test-frameworks (JsTestDriver built in)
  • Your own assertions/refutes
  • Reporters (xUnit XML, traditional dots, specification, tap, TeamCity and more built-in)
  • Customize/replace the HTML that is used to run the browser-tests
• TextMate and Emacs integration

Cons:

• Stil in beta so can be buggy
• No plugin for Eclipse/IntelliJ (yet)
• Doesn't group results by os/browser/version like TestSwarm *. It does, however, print out the browser name and version in the test results.
• No history of previous test results like TestSwarm *
• Doesn't fully work on windows as of May 2014

* TestSwarm is also a Continuous Integration server, while you need a separate CI server for Buster.js. It does, however, output xUnit XML reports, so it should be easy to integrate with Hudson, Bamboo or other CI servers.

TestSwarm

https://github.com/jquery/testswarm

TestSwarm is officially no longer under active development as stated on their GitHub webpage. They recommend Karma, browserstack-runner, or Intern.

Jasmine

This is a behavior-driven framework (as stated in quote below) that might interest developers familiar with Ruby or Ruby on Rails. The syntax is based on RSpec that are used for testing in Rails projects.

Jasmine specs can be run from an html page (in qUnit fashion) or from a test runner (as Karma).

Jasmine is a behavior-driven development framework for testing your JavaScript code. It does not depend on any other JavaScript frameworks. It does not require a DOM.

If you have experience with this testing framework, please contribute with more info :)

Project home: http://jasmine.github.io/

QUnit

QUnit focuses on testing JavaScript in the browser while providing as much convenience to the developer as possible. Blurb from the site:

QUnit is a powerful, easy-to-use JavaScript unit test suite. It's used by the jQuery, jQuery UI, and jQuery Mobile projects and is capable of testing any generic JavaScript code

QUnit shares some history with TestSwarm (above):

QUnit was originally developed by John Resig as part of jQuery. In 2008 it got its own home, name and API documentation, allowing others to use it for their unit testing as well. At the time it still depended on jQuery. A rewrite in 2009 fixed that, now QUnit runs completely standalone. QUnit's assertion methods follow the CommonJS Unit Testing specification, which was to some degree influenced by QUnit.

Project home: http://qunitjs.com/

Sinon

Another great tool is sinon.js by Christian Johansen, the author of Test-Driven JavaScript Development. Best described by himself:

Standalone test spies, stubs and mocks for JavaScript. No dependencies works with any unit testing framework.

Intern

The Intern Web site provides a direct feature comparison to the other testing frameworks on this list. It offers more features out of the box than any other JavaScript-based testing system.

JEST

A new but yet very powerful testing framework. It allows snapshot based testing as well this increases the testing speed and creates a new dynamic in terms of testing

Check out one of their talks: https://www.youtube.com/watch?v=cAKYQpTC7MA

Better yet: Getting Started

Did you set the section header height in the viewDidLoad?

self.tableView.sectionHeaderHeight = 70

Plus you should replace

self.view.addSubview(view)

by

view.addSubview(label)

Finally you have to check your frames

let view = UIView(frame: CGRect.zeroRect)

and eventually the desired text color as it seems to be currently white on white.

The default height is 44.0f for a tableview cell I believe. You must be having your datasource in hand in a Array? Then just check if [array count]*44.0f goes beyond the frame bounds and if so set tableview.scrollEnabled = NO, else set it to YES. Do it where you figure the datasource out for that particular tableview.

I was reading path from a properties file and didn't mention there was a space in the end. Make sure you don't have one.

The CPP Section of the GCC Manual indicates that header files may be located in the following directories:

GCC looks in several different places for headers. On a normal Unix system, if you do not instruct it otherwise, it will look for headers requested with #include in:

 /usr/local/include
 libdir/gcc/target/version/include
 /usr/target/include
 /usr/include

For C++ programs, it will also look in /usr/include/g++-v3, first.

You can use the LocalForward directive in your host yam section of ~/.ssh/config:

LocalForward 5901 computer.myHost.edu:5901

You could use a GET request to get the page content and then display that data using the Webview , this way you are not using multiple server calls. Alternative you can use Javascript to check the DOM object for validity.

Variables are not defined, but declared.

This is possible duplicate of declare variables in a pl/sql block

But you can look here :

http://docs.oracle.com/cd/B19306_01/appdev.102/b14261/fundamentals.htm#i27306

http://docs.oracle.com/cd/B19306_01/appdev.102/b14261/overview.htm

UPDATE:

Refer here : How to return a resultset / cursor from a Oracle PL/SQL anonymous block that executes Dynamic SQL?

If the branches are only local, you can use -d if the branch has been merged, like

git branch -d branch-name

If the branch contains code you never plan on merging, use -D instead.

If the branch is in the upstream repo (on Bitbucket) you can remove the remote reference by

git push origin :branch-name

Also, if you're on the Bitbucket website, you can remove branches you've pushed by going to the Feature branches tab under Commits on the site. There you'll find an ellipsis icon. Click that, then choose Delete branch. Just be sure you want to drop all the changes there!

You just need the $('button').prop('disabled', true); part, the button will automatically take the disabled class.

This code is contained within a jUnit test class I use to test if a connection is available. I always receive a connection, but if you check the content length it should be -1 if not known :

  try {
    URL url = new URL("http://www.google.com");
    URLConnection connection = url.openConnection();

    if(connection.getContentLength() == -1){
          fail("Failed to verify connection");
    }
  } 
  catch (IOException e) {
      fail("Failed to open a connection");
      e.printStackTrace();
  }

Try this, it worked for me.

Example for insert into values in One database table into another database table

insert into dbo.onedatabase.FolderStatus
(
  [FolderStatusId],
  [code],
  [title],
  [last_modified]
)

select [FolderStatusId], [code], [title], [last_modified]
from dbo.Twodatabase.f_file_stat

Some databases are designed to communicate over the web using ports assigned by the Internet Assigned Number Authority (IANA) and when run on individual PC use the ports with localhost. Some common databases with their default ports (the defualts can usually be overridden):

Port Database

1433 Microsoft SQL Server https://support.microsoft.com/en-us/kb/287932

3306 MySQL https://dev.mysql.com/doc/refman/4.1/en/connecting.html

5432 PostgreSQL

1527 Apache Derby (database)

Some web servers and databases are paired together such as Apache/MySQL (as in LAMP or XXAMP) or MS Internet Information Server (IIS)/MS SQL Server (IIS/SQL Server) in which case you have to be concerned with both the port of the database and the web server -- a common example of this is WordPress which uses Apache/MySQL.

The java.lang.management package does give you a whole lot more info than Runtime - for example it will give you heap memory (ManagementFactory.getMemoryMXBean().getHeapMemoryUsage()) separate from non-heap memory (ManagementFactory.getMemoryMXBean().getNonHeapMemoryUsage()).

You can also get process CPU usage (without writing your own JNI code), but you need to cast the java.lang.management.OperatingSystemMXBean to a com.sun.management.OperatingSystemMXBean. This works on Windows and Linux, I haven't tested it elsewhere.

For example ... call the get getCpuUsage() method more frequently to get more accurate readings.

public class PerformanceMonitor { 
    private int  availableProcessors = getOperatingSystemMXBean().getAvailableProcessors();
    private long lastSystemTime      = 0;
    private long lastProcessCpuTime  = 0;

    public synchronized double getCpuUsage()
    {
        if ( lastSystemTime == 0 )
        {
            baselineCounters();
            return;
        }

        long systemTime     = System.nanoTime();
        long processCpuTime = 0;

        if ( getOperatingSystemMXBean() instanceof OperatingSystemMXBean )
        {
            processCpuTime = ( (OperatingSystemMXBean) getOperatingSystemMXBean() ).getProcessCpuTime();
        }

        double cpuUsage = (double) ( processCpuTime - lastProcessCpuTime ) / ( systemTime - lastSystemTime );

        lastSystemTime     = systemTime;
        lastProcessCpuTime = processCpuTime;

        return cpuUsage / availableProcessors;
    }

    private void baselineCounters()
    {
        lastSystemTime = System.nanoTime();

        if ( getOperatingSystemMXBean() instanceof OperatingSystemMXBean )
        {
            lastProcessCpuTime = ( (OperatingSystemMXBean) getOperatingSystemMXBean() ).getProcessCpuTime();
        }
    }
}

A more concise--but not necessarily faster--method is to use DataFrame.isin() and DataFrame.any()

In [27]: n = 10

In [28]: df = DataFrame(randint(4, size=(n, 2)), columns=list('ab'))

In [29]: df
Out[29]:
   a  b
0  0  0
1  1  1
2  1  1
3  2  3
4  2  3
5  0  2
6  1  2
7  3  0
8  1  1
9  2  2

[10 rows x 2 columns]

In [30]: df.isin([1, 2])
Out[30]:
       a      b
0  False  False
1   True   True
2   True   True
3   True  False
4   True  False
5  False   True
6   True   True
7  False  False
8   True   True
9   True   True

[10 rows x 2 columns]

In [31]: df.isin([1, 2]).any(1)
Out[31]:
0    False
1     True
2     True
3     True
4     True
5     True
6     True
7    False
8     True
9     True
dtype: bool

In [32]: df.loc[df.isin([1, 2]).any(1)]
Out[32]:
   a  b
1  1  1
2  1  1
3  2  3
4  2  3
5  0  2
6  1  2
8  1  1
9  2  2

[8 rows x 2 columns]

The way to do it is to pass the tasks a callback that updates a shared counter. When the shared counter reaches zero you know that all tasks have finished so you can continue with your normal flow.

var ntasks_left_to_go = 4;

var callback = function(){
    ntasks_left_to_go -= 1;
    if(ntasks_left_to_go <= 0){
         console.log('All tasks have completed. Do your stuff');
    }
}

task1(callback);
task2(callback);
task3(callback);
task4(callback);

Of course, there are many ways to make this kind of code more generic or reusable and any of the many async programing libraries out there should have at least one function to do this kind of thing.

To avoid the global lock, you can use SingletonCache to implement one lock per key, without exploding memory usage (the lock objects are removed when no longer referenced, and acquire/release is thread safe guaranteeing that only 1 instance is ever in use via compare and swap).

Using it looks like this:

SingletonCache<string, object> keyLocks = new SingletonCache<string, object>();

const string CacheKey = "CacheKey";
static string GetCachedData()
{
    string expensiveString =null;
    if (MemoryCache.Default.Contains(CacheKey))
    {
        return MemoryCache.Default[CacheKey] as string;
    }

    // double checked lock
    using (var lifetime = keyLocks.Acquire(url))
    {
        lock (lifetime.Value)
        {
           if (MemoryCache.Default.Contains(CacheKey))
           {
              return MemoryCache.Default[CacheKey] as string;
           }

           cacheItemPolicy cip = new CacheItemPolicy()
           {
              AbsoluteExpiration = new DateTimeOffset(DateTime.Now.AddMinutes(20))
           };
           expensiveString = SomeHeavyAndExpensiveCalculation();
           MemoryCache.Default.Set(CacheKey, expensiveString, cip);
           return expensiveString;
        }
    }      
}

Code is here on GitHub: https://github.com/bitfaster/BitFaster.Caching

Install-Package BitFaster.Caching

There is also an LRU implementation that is lighter weight than MemoryCache, and has several advantages - faster concurrent reads and writes, bounded size, no background thread, internal perf counters etc. (disclaimer, I wrote it).

Instead of concatenating paths like in some answers, I use File.expand_path:

Dir[File.expand_path('importers/*.rb', File.dirname(__FILE__))].each do |file|
  require file
end

Update:

Instead of using File.dirname you could do the following:

Dir[File.expand_path('../importers/*.rb', __FILE__)].each do |file|
  require file
end

Where .. strips the filename of __FILE__.

Encountered the same error in below Usecase.

I tried to hit the Rest(Put mapping) end point using sprint boot(2.0.0 Snapshot Version) without having default constructor in respective bean.

But with latest Spring Boot versions(2.4.1 Version) the same piece of code is working without error.

so the bean default constructor is no longer needed in latest version of Spring Boot

FYI

Using netbeans New Entity Classes from Database with a mysql *auto_increment* column, creates you an attribute with the following annotations:

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "id")
@NotNull
private Integer id;

This was getting me the same an error saying the column must not be null, so i simply removed the @NotNull anotation leaving the attribute null, and it works!

I couldn't find a rationale by the original developers this quickly, but I can give you an educated guess based on a few years of Git experience.

No, not every branch is something you want to push to the outside world. It might represent a private experiment.

Moreover, where should git push send all the branches? Git can work with multiple remotes and you may want to have different sets of branches on each. E.g. a central project GitHub repo may have release branches; a GitHub fork may have topic branches for review; and a local Git server may have branches containing local configuration. If git push would push all branches to the remote that the current branch tracks, this kind of scheme would be easy to screw up.

Select first the text you want to format and then press Ctrl+I.

Use Cmd+A first if you wish to format all text in the selected file.

Note: this procedure only re-indents the lines, it does not do any advanced formatting.

The new key binding to re-indent is control+I.

I think that the beginning of your query should look like that:

    co.ccnum [FuelFirst Card #], 
    co.dtentered [Date Entered],

        WHEN 0 THEN st.ccstatustypename 
        ELSE 'Unknown' 
    END [Status],
    CASE st.ccstatustypename 
        WHEN 'Active' THEN ' ' 
        WHEN 'Not Active' THEN ' ' 
        ELSE st.ccstatustypename

I use the latest version of SSMS or sql server management studio. I have a SQL script (in query editor) which has about 100 lines of code. This is error I got in the query:

Msg 245, Level 16, State 1, Line 2
Conversion failed when converting the nvarchar value 'abcd' to data type int.

Solution - I had seen this kind of error before when I forgot to enclose a number (in varchar column) in single quotes.

As an aside, the error message is misleading. The actual error on line number 70 in the query editor and not line 2 as the error says!

SELECT DATE_FORMAT(COLUMN_NAME, "%d/%m/%Y %h:%i %p");

OR

SELECT DATE_FORMAT("2019-05-10 19:30:10", "%d/%m/%Y %h:%i %p");

OUTPUT is 10/05/2019 07:30 PM

String[] is an array of Strings. Such an array is internally a class. Like all classes that don't explicitly extend some other class, it extends Object implicitly. The method toString() of class Object, by default, gives you the representation you see: the class name, followed by @, followed by the hash code in hex. Since the String[] class doesn't override the toString() method, you get that as a result.

Create some method that outputs the array elements for you. Iterate over the array and use System.out.print() (not print*ln*) on the elements.

I am a beginner so here is a beginners answer. The if in the for loop gives i which can then be used however needed such as Numbers[i] in another vector. Most is fluff for examples sake, the for/if really says it all.

int main(){
vector<string>names{"Sara", "Harold", "Frank", "Taylor", "Sasha", "Seymore"};
string req_name;
cout<<"Enter search name: "<<'\n';
cin>>req_name;
    for(int i=0; i<=names.size()-1; ++i) {
        if(names[i]==req_name){
            cout<<"The index number for "<<req_name<<" is "<<i<<'\n';
            return 0;
        }
        else if(names[i]!=req_name && i==names.size()-1) {
            cout<<"That name is not an element in this vector"<<'\n';
        } else {
            continue;
        }
    }

In my case only given solution worked fine.

Judging from what you've posted, and assuming it's not a typo, Eclipse is looking in C:\s\platform-tools...

If that's the case, then you should check Eclipse's Window/Preferences/Android option for the SDK Location. Maybe yours is set to "C:\s". You can't edit it to be a value such as that without causing an error, but maybe it's got corrupted somehow.

it is similar with mattgen88, but I just fixed CURLOPT_HEADER, and redefine array for it work in domain.com host server. this one doesn't work on my xampp localhost. Those small error but took long to figure out. this code was tested on domain.com hosting.

   $privatekey = 'your google captcha private key';

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "https://www.google.com/recaptcha/api/siteverify");
    curl_setopt($ch, CURLOPT_HEADER, 'Content-Type: application/json');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, array(
        'secret' => $privatekey,
        'response' => $_POST['g-recaptcha-response'],
        'remoteip' => $_SERVER['REMOTE_ADDR']
    )
               );

    $resp = json_decode(curl_exec($ch));
    curl_close($ch);

    if ($resp->success) {
        // Success
        echo 'captcha';
    } else {
        // failure
        echo 'no captcha';
    }

Setting up borders in the style used in the cells will accomplish this. Example:

style.setBorderBottom(HSSFCellStyle.BORDER_MEDIUM);
style.setBorderTop(HSSFCellStyle.BORDER_MEDIUM);
style.setBorderRight(HSSFCellStyle.BORDER_MEDIUM);
style.setBorderLeft(HSSFCellStyle.BORDER_MEDIUM);

I liked this:

new_column = np.zeros((len(a), 1))
b = np.block([a, new_column])

I will admit up front that this answer does not answer the original question, that of generally being able to access the Manifest. However if what is really required is to read one of a number of "standard" Manifest attributes, the following solution is much simpler than those posted above. So I hope that the moderator will allow it. Note that this solution is in Kotlin, not Java, but I would expect that a port to Java would be trivial. (Although I admit I don't know the Java equivalent of ".`package`".

In my case I wanted to read the attribute "Implementation-Version" so I started with the solutions given above to obtain the stream and then read it to obtain the value. While this solution worked, a coworker reviewing my code showed me an easier way to do what I wanted. Note that this solution is in Kotlin, not Java.

val myPackage = MyApplication::class.java.`package`
val implementationVersion = myPackage.implementationVersion

Once again note that this does not answer the original question, in particular "Export-package" does not seem to be one of the supported attributes. That said, there is a myPackage.name that returns a value. Perhaps someone who understands this more than I can comment on whether that returns the value the original poster is requesting.

I had also faced this issue. NO it will not affect your original repo by anyway. just simply delete it by entering the name of forked repo

Look at the const and static section of the Rust book.

You can use something as follows:

const N: i32 = 5; 

or

static N: i32 = 5;

in global space.

But these are not mutable. For mutability, you could use something like:

static mut N: i32 = 5;

Then reference them like:

unsafe {
    N += 1;

    println!("N: {}", N);
}

add this line end of php.ini

openssl.cafile=/opt/lampp/share/curl/curl-ca-bundle.crt

may be curl path cannot be identified by PHP

I am unsure if the author originally was just asking whether or not this allows duplicate values or if there was an implied question here asking, "How to allow duplicate NULL values while using UNIQUE?" Or "How to only allow one UNIQUE NULL value?"

The question has already been answered, yes you can have duplicate NULL values while using the UNIQUE index.

Since I stumbled upon this answer while searching for "how to allow one UNIQUE NULL value." For anyone else who may stumble upon this question while doing the same, the rest of my answer is for you...

In MySQL you can not have one UNIQUE NULL value, however you can have one UNIQUE empty value by inserting with the value of an empty string.

Warning: Numeric and types other than string may default to 0 or another default value.

You were looking for help on installations with pip. You can find it with the following command:

pip install --help

Running pip install -e /path/to/package installs the package in a way, that you can edit the package, and when a new import call looks for it, it will import the edited package code. This can be very useful for package development.

There's a workaround for IE - use inline SVG and set pointer-events="none" in SVG. See my answer in How to make Internet Explorer emulate pointer-events:none?

We face this issue but had different reason, here is the reason:

In our project found multiple bean entry with same bean name. 1 in applicationcontext.xml & 1 in dispatcherServlet.xml

Example:

<bean name="dataService" class="com.app.DataServiceImpl">
<bean name="dataService" class="com.app.DataServiceController">

& we are trying to autowired by dataService name.

Solution: we changed the bean name & its solved.

I wrote a simple library for manipulating the JavaScript date object. You can try this:

var dateString = timeSolver.getString(new Date(), "YYYY/MM/DD HH:MM:SS.SSS")

Library here: https://github.com/sean1093/timeSolver

I store my data this way:

accountsTable ->
  key1 -> account1
  key2 -> account2

in order to get object data:

accountsDb = mDatabase.child("accountsTable");

accountsDb.child("some   key").addListenerForSingleValueEvent(new ValueEventListener() {
                @Override
                public void onDataChange(DataSnapshot snapshot) {

                    try{

                        Account account  = snapshot.getChildren().iterator().next()
                                  .getValue(Account.class);


                    } catch (Throwable e) {
                        MyLogger.error(this, "onCreate eror", e);
                    }
                }
                @Override public void onCancelled(DatabaseError error) { }
            });

declare @xx int 
set     @xx = 3 
select @xx      
select @xx * 2  -- yields another integer  
select @xx/1    -- same
select @xx/1.0  --yields 6 decimal places 
select @xx/1.00 --       6 
select @xx * 1.0  --     1 decimal place - victory
select @xx * 1.00 --     2         places - hooray 

Also _ inserting an int into a temp_table with like decimal(10,3) _ works ok.

Based on the existing answers, here's a step-by-step guide to sending automated e-mails over SMTP, using a GMail account, from the command line, without disclosing the password.

Requirements

First, install the following software packages:

• Expect
• OpenSSL
• Core Utils (base64)

These instructions assume a Linux operating system, but should be reasonably easy to port to Windows (via Cygwin or native equivalents), or other operating system.

Authentication

Save the following shell script as authentication.sh:

#!/bin/bash

# Asks for a username and password, then spits out the encoded value for
# use with authentication against SMTP servers.

echo -n "Email (shown): "
read email
echo -n "Password (hidden): "
read -s password
echo

TEXT="\0$email\0$password"

echo -ne $TEXT | base64

Make it executable and run it as follows:

chmod +x authentication.sh
./authentication.sh

When prompted, provide your e-mail address and password. This will look something like:

Email (shown): [email protected]
Password (hidden): 
AGJvYkBnbWFpbC5jb20AYm9iaXN0aGViZXN0cGVyc29uZXZlcg==

Copy the last line (AGJ...==), as this will be used for authentication.

Notification

Save the following expect script as notify.sh (note the first line refers to the expect program):

#!/usr/bin/expect

set address "[lindex $argv 0]"
set subject "[lindex $argv 1]"
set ts_date "[lindex $argv 2]"
set ts_time "[lindex $argv 3]"

set timeout 10
spawn openssl s_client -connect smtp.gmail.com:465 -crlf -ign_eof 

expect "220" {
  send "EHLO localhost\n"

  expect "250" {
    send "AUTH PLAIN YOUR_AUTHENTICATION_CODE\n"

    expect "235" {
      send "MAIL FROM: <YOUR_EMAIL_ADDRESS>\n"

      expect "250" {
        send "RCPT TO: <$address>\n"

        expect "250" {
          send "DATA\n"

          expect "354" {
            send "Subject: $subject\n\n"
            send "Email sent on $ts_date at $ts_time.\n"
            send "\n.\n"

            expect "250" {
                send "quit\n"
            }
          }
        }
      }
    }
  }
}

Make the following changes:

1. Paste over YOUR_AUTHENTICATION_CODE with the authentication code generated by the authentication script.
2. Change YOUR_EMAIL_ADDRESS with the e-mail address used to generate the authentication code.
3. Save the file.

For example (note the angle brackets are retained for the e-mail address):

send "AUTH PLAIN AGJvYkBnbWFpbC5jb20AYm9iaXN0aGViZXN0cGVyc29uZXZlcg==\n"
send "MAIL FROM: <[email protected]>\n"

Lastly, make the notify script executable as follows:

chmod +x notify.sh

Send E-mail

Send an e-mail from the command line as follows:

./notify.sh [email protected] "Command Line" "March 14" "15:52"

Since iOS 8 came out, this problem does not exist any more. The scroll event is now fired smoothly in iOS Safari as well.

So, if you register the scroll event handler and check window.pageYOffset inside that event handler, everything works just fine.

<?php foreach ($sidemenus->mname as $sidemenu): ?>
<?php echo $sidemenu ."<br />";?>

or

$sidemenus = mysql_fetch_array($results);

then

<?php echo $sidemenu['mname']."<br />";?>

You could do this using an IF statement:

IF NOT EXISTS 
    (   SELECT  1
        FROM    tblSoftwareTitles 
        WHERE   Softwarename = @SoftwareName 
        AND     SoftwareSystemType = @Softwaretype
    )
    BEGIN
        INSERT tblSoftwareTitles (SoftwareName, SoftwareSystemType) 
        VALUES (@SoftwareName, @SoftwareType) 
    END;

You could do it without IF using SELECT

INSERT  tblSoftwareTitles (SoftwareName, SoftwareSystemType) 
SELECT  @SoftwareName,@SoftwareType
WHERE   NOT EXISTS 
        (   SELECT  1
            FROM    tblSoftwareTitles 
            WHERE   Softwarename = @SoftwareName 
            AND     SoftwareSystemType = @Softwaretype
        );

Both methods are susceptible to a race condition, so while I would still use one of the above to insert, but you can safeguard duplicate inserts with a unique constraint:

CREATE UNIQUE NONCLUSTERED INDEX UQ_tblSoftwareTitles_Softwarename_SoftwareSystemType
    ON tblSoftwareTitles (SoftwareName, SoftwareSystemType);

Example on SQL-Fiddle

ADDENDUM

In SQL Server 2008 or later you can use MERGE with HOLDLOCK to remove the chance of a race condition (which is still not a substitute for a unique constraint).

MERGE tblSoftwareTitles WITH (HOLDLOCK) AS t
USING (VALUES (@SoftwareName, @SoftwareType)) AS s (SoftwareName, SoftwareSystemType) 
    ON s.Softwarename = t.SoftwareName 
    AND s.SoftwareSystemType = t.SoftwareSystemType
WHEN NOT MATCHED BY TARGET THEN 
    INSERT (SoftwareName, SoftwareSystemType) 
    VALUES (s.SoftwareName, s.SoftwareSystemType);

Example of Merge on SQL Fiddle

int min = 65;
int max = 80;

Random r = new Random();
int i1 = r.nextInt(max - min + 1) + min;

Note that nextInt(int max) returns an int between 0 inclusive and max exclusive. Hence the +1.

A recursive solution using ternary operators.

public static int fac(int n) {
    return (n < 1) ? 1 : n*fac(n-1);
}

In response to user007:

If the height of your element is changing due to items being appended to it using .append() you shouldn't need to detect the change in height. Simply add the reposition of your second element in the same function where you are appending the new content to your first element.

As in:

Working Example

$('.class1').click(function () {
    $('.class1').append("<div class='newClass'><h1>This is some content</h1></div>");
    $('.class2').css('top', $('.class1').offset().top + $('.class1').outerHeight());
});

String.contains

String.contains works with String, period. It doesn't work with regex. It will check whether the exact String specified appear in the current String or not.

Note that String.contains does not check for word boundary; it simply checks for substring.

Regex solution

Regex is more powerful than String.contains, since you can enforce word boundary on the keywords (among other things). This means you can search for the keywords as words, rather than just substrings.

Use String.matches with the following regex:

"(?s).*\\bstores\\b.*\\bstore\\b.*\\bproduct\\b.*"

The RAW regex (remove the escaping done in string literal - this is what you get when you print out the string above):

(?s).*\bstores\b.*\bstore\b.*\bproduct\b.*

The \b checks for word boundary, so that you don't get a match for restores store products. Note that stores 3store_product is also rejected, since digit and _ are considered part of a word, but I doubt this case appear in natural text.

Since word boundary is checked for both sides, the regex above will search for exact words. In other words, stores stores product will not match the regex above, since you are searching for the word store without s.

. normally match any character except a number of new line characters. (?s) at the beginning makes . matches any character without exception (thanks to Tim Pietzcker for pointing this out).

Here the code i used for my app

This code will take a image from url and convert is to a byte array

byte[] logoImage = getLogoImage(IMAGEURL);

private byte[] getLogoImage(String url){
     try {
             URL imageUrl = new URL(url);
             URLConnection ucon = imageUrl.openConnection();

             InputStream is = ucon.getInputStream();
             BufferedInputStream bis = new BufferedInputStream(is);

             ByteArrayBuffer baf = new ByteArrayBuffer(500);
             int current = 0;
             while ((current = bis.read()) != -1) {
                  baf.append((byte) current);
             }

             return baf.toByteArray();
     } catch (Exception e) {
          Log.d("ImageManager", "Error: " + e.toString());
     }
     return null;
}

To save the image to db i used this code.

 public void insertUser(){
        SQLiteDatabase db = dbHelper.getWritableDatabase();
        String delSql = "DELETE FROM ACCOUNTS";
        SQLiteStatement delStmt = db.compileStatement(delSql);
        delStmt.execute();

        String sql = "INSERT INTO ACCOUNTS (account_id,account_name,account_image) VALUES(?,?,?)";
        SQLiteStatement insertStmt = db.compileStatement(sql);
        insertStmt.clearBindings();
        insertStmt.bindString(1, Integer.toString(this.accId));
        insertStmt.bindString(2,this.accName);
        insertStmt.bindBlob(3, this.accImage);
        insertStmt.executeInsert();
        db.close();
}

To retrieve the image back this is code i used.

public Account getCurrentAccount() {
    SQLiteDatabase db = dbHelper.getWritableDatabase();
    String sql = "SELECT * FROM ACCOUNTS";
    Cursor cursor = db.rawQuery(sql, new String[] {});

    if(cursor.moveToFirst()){
        this.accId  = cursor.getInt(0);
        this.accName = cursor.getString(1);
        this.accImage = cursor.getBlob(2);
    }
    if (cursor != null && !cursor.isClosed()) {
        cursor.close();
    }
    db.close();
    if(cursor.getCount() == 0){
        return null;
    } else {
        return this;
    }
}

Finally to load this image to a imageview

logoImage.setImageBitmap(BitmapFactory.decodeByteArray( currentAccount.accImage, 
        0,currentAccount.accImage.length));

I'm not sure about older versions, but from NEON onward, you can just right click on workspace and select Remove from launcher selection option.

of course this won't remove the original files. It simply removes it from the list of suggested workspaces.

I had the same problem, it was a missing manifest.json file, if not found the browser decide with orientation is best fit, if you don't specify the file or use a wrong path.

I fixed just calling the manifest.json correctly on html headers.

My html headers:

<meta name="application-name" content="App Name">
<meta name="mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black" />
<link rel="manifest" href="manifest.json">
<meta name="msapplication-starturl" content="/">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<meta name="theme-color" content="#">
<meta name="msapplication-TileColor" content="#">
<meta name="msapplication-config" content="browserconfig.xml">
<link rel="icon" type="image/png" sizes="192x192" href="android-chrome-192x192.png">
<link rel="apple-touch-icon" sizes="180x180" href="apple-touch-icon.png">
<link rel="mask-icon" href="safari-pinned-tab.svg" color="#ffffff">
<link rel="shortcut icon" href="favicon.ico">

And the manifest.json file content:

{
  "display": "standalone",
  "orientation": "portrait",
  "start_url": "/",
  "theme_color": "#000000",
  "background_color": "#ffffff",
  "icons": [
  {
    "src": "android-chrome-192x192.png",
    "sizes": "192x192",
    "type": "image/png"
  }
}

To generate your favicons and icons use this webtool: https://realfavicongenerator.net/

To generate your manifest file use: https://tomitm.github.io/appmanifest/

        Notes:
        Microsoft changed the UuidCreate function so it no longer uses the machine's MAC address as part of the UUID. Since CoCreateGuid calls UuidCreate to get its GUID, its output also changed. If you still like the GUIDs to be generated in sequential order (helpful for keeping a related group of GUIDs together in the system registry), you can use the UuidCreateSequential function.

        CoCreateGuid generates random-looking GUIDs like these:

The accepted answer shows the correct way to setState but it does not lead to a well functioning select box.

import React, { useState } from "react"; 
import ReactDOM from "react-dom";

const initialValue = { id: 0,value: " --- Select a State ---" };

const options = [
    { id: 1, value: "Alabama" },
    { id: 2, value: "Georgia" },
    { id: 3, value: "Tennessee" }
];

const StateSelector = () => {   
   const [ selected, setSelected ] = useState(initialValue);  

     return (
       <div>
          <label>Select a State:</label>
          <select value={selected}>
            {selected === initialValue && 
                <option disabled value={initialValue}>{initialValue.value}</option>}
            {options.map((localState, index) => (
               <option key={localState.id} value={localState}>
                   {localState.value}
               </option>
             ))}
          </select>
        </div>
      ); 
};

const rootElement = document.getElementById("root");
ReactDOM.render(<StateSelector />, rootElement);

My guess is it's not in your path.
in bash, try:
echo $PATH
and
sudo which nginx
And see if the folder containing nginx is also in your $PATH variable.
If not, either add the folder to your path environment variable, or create an alias (and put it in your .bashrc) ooor your could create a link i guess.
or sudo nginx -v if you just want that...

To develop the answer of @Caumons:

Imagine one father class has many children and there is a need to add a common field into that class. If you consider the mentioned approach, you should go to each children class one by one and refactor their constructors for the new field. therefore that solution is not a promising solution in this scenario

Now take a look at this solution.

A father can receive an self object from each children. Here is a father class:

public class Father {

    protected String fatherField;

    public Father(Father a){
        fatherField = a.fatherField;
    }

    //Second constructor
    public Father(String fatherField){
        this.fatherField = fatherField;
    }

    //.... Other constructors + Getters and Setters for the Fields
}

Here is our child class that should implement one of its father constructor, in this case the aforementioned constructor :

public class Child extends Father {

    protected String childField;

    public Child(Father father, String childField ) {
        super(father);
        this.childField = childField;
    }

    //.... Other constructors + Getters and Setters for the Fields

    @Override
    public String toString() {
        return String.format("Father Field is: %s\nChild Field is: %s", fatherField, childField);
    }
}

Now we test out application:

public class Test {
    public static void main(String[] args) {
        Father fatherObj = new Father("Father String");
        Child child = new Child(fatherObj, "Child String");
        System.out.println(child);
    }
}

And here is the result :

Father Field is: Father String

Child Field is: Child String

Now you can easily add new fields to father class without being worried of your children codes to break;

You can also count on multiple groups and their intersection:

self.session.query(func.count(Table.column1),Table.column1, Table.column2).group_by(Table.column1, Table.column2).all()

The query above will return counts for all possible combinations of values from both columns.

Due to this answers high search placing I thought the LINQ OrderBy solution is worth showing:

class Person
{
    public Person(string firstname, string lastname)
    {
        FirstName = firstname;
        LastName = lastname;
    }
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

static void Main(string[] args)
{
    Dictionary<Person, int> People = new Dictionary<Person, int>();

    People.Add(new Person("John", "Doe"), 1);
    People.Add(new Person("Mary", "Poe"), 2);
    People.Add(new Person("Richard", "Roe"), 3);
    People.Add(new Person("Anne", "Roe"), 4);
    People.Add(new Person("Mark", "Moe"), 5);
    People.Add(new Person("Larry", "Loe"), 6);
    People.Add(new Person("Jane", "Doe"), 7);

    foreach (KeyValuePair<Person, int> person in People.OrderBy(i => i.Key.LastName))
    {
        Debug.WriteLine(person.Key.LastName + ", " + person.Key.FirstName + " - Id: " + person.Value.ToString());
    }
}

Output:

Doe, John - Id: 1
Doe, Jane - Id: 7
Loe, Larry - Id: 6
Moe, Mark - Id: 5
Poe, Mary - Id: 2
Roe, Richard - Id: 3
Roe, Anne - Id: 4

In this example it would make sense to also use ThenBy for first names:

foreach (KeyValuePair<Person, int> person in People.OrderBy(i => i.Key.LastName).ThenBy(i => i.Key.FirstName))

Then the output is:

Doe, Jane - Id: 7
Doe, John - Id: 1
Loe, Larry - Id: 6
Moe, Mark - Id: 5
Poe, Mary - Id: 2
Roe, Anne - Id: 4
Roe, Richard - Id: 3

LINQ also has the OrderByDescending and ThenByDescending for those that need it.

It's easier using Array.filter:

var unique = arr.filter(function(elem, index, self) {
    return index === self.indexOf(elem);
})

Numeric defines the TOTAL number of digits, and then the number after the decimal.

A numeric(3,2) can only hold up to 9.99.

I've just set up a quick benchmarking exercise:

Function             time to run 1 million iterations
--------------------------------------------
(int) "123":                0.55029
intval("123"):              1.0115  (183%)

(int) "0":                  0.42461
intval("0"):                0.95683 (225%)

(int) int:                  0.1502
intval(int):                0.65716 (438%)

(int) array("a", "b"):      0.91264
intval(array("a", "b")):    1.47681 (162%)

(int) "hello":              0.42208
intval("hello"):            0.93678 (222%)

On average, calling intval() is two and a half times slower, and the difference is the greatest if your input already is an integer.

I'd be interested to know why though.

Update: I've run the tests again, this time with coercion (0 + $var)

| INPUT ($x)      |  (int) $x  |intval($x) |  0 + $x   |
|-----------------|------------|-----------|-----------|
| "123"           |   0.51541  |  0.96924  |  0.33828  |
| "0"             |   0.42723  |  0.97418  |  0.31353  |
| 123             |   0.15011  |  0.61690  |  0.15452  |
| array("a", "b") |   0.8893   |  1.45109  |  err!     |
| "hello"         |   0.42618  |  0.88803  |  0.1691   |
|-----------------|------------|-----------|-----------|

Addendum: I've just come across a slightly unexpected behaviour which you should be aware of when choosing one of these methods:

$x = "11";
(int) $x;      // int(11)
intval($x);    // int(11)
$x + 0;        // int(11)

$x = "0x11";
(int) $x;      // int(0)
intval($x);    // int(0)
$x + 0;        // int(17) !

$x = "011";
(int) $x;      // int(11)
intval($x);    // int(11)
$x + 0;        // int(11) (not 9)

Maybe :active over :focus with :hover will help! Try

button {
background:lime;
}

button:hover {
background:green;
}

button:focus {
background:gray;
}

button:active {
background:red;
}

Then:

<button onkeydown="alerted_of_key_pressed()" id="button" title="Test button" href="#button">Demo</button>

Then:

<!--JAVASCRIPT-->
<script>
function alerted_of_key_pressed() { alert("You pressed a key when hovering over this button.") }
</script>

 Sorry about that last one. :) I was just showing you a cool function!

"Best" helpdesk system is very subjective, of course, but I recommend Request Tracker (aka RT).

It has a default workflow built in, but is easily configured for alternate workflows using the "Scrips" and templates. Very extensible if you want.

I met the same issue while experimenting with my own Python library and what I've found out is that pip freeze will show you the library as installed if your current directory contains lib.egg-info folder. And pip uninstall <lib> will give you the same error message.

1. Make sure your current directory doesn't have any egg-info folders
2. Check pip show <lib-name> to see the details about the location of the library, so you can remove files manually.

Set sh1 = Worksheets(filenum(lngPosition)).Activate

You are getting Subscript out of range error error becuase it cannot find that Worksheet.

The good news is a transaction in SQL Server can span multiple batches (each exec is treated as a separate batch.)

You can wrap your EXEC statements in a BEGIN TRANSACTION and COMMIT but you'll need to go a step further and rollback if any errors occur.

Ideally you'd want something like this:

BEGIN TRY
    BEGIN TRANSACTION 
        exec( @sqlHeader)
        exec(@sqlTotals)
        exec(@sqlLine)
    COMMIT
END TRY
BEGIN CATCH

    IF @@TRANCOUNT > 0
        ROLLBACK
END CATCH

The BEGIN TRANSACTION and COMMIT I believe you are already familiar with. The BEGIN TRY and BEGIN CATCH blocks are basically there to catch and handle any errors that occur. If any of your EXEC statements raise an error, the code execution will jump to the CATCH block.

Your existing SQL building code should be outside the transaction (above) as you always want to keep your transactions as short as possible.

yield is similar to return. The difference is:

yield makes a function iterable (in the following example primes(n = 1) function becomes iterable).
What it essentially means is the next time the function is called, it will continue from where it left (which is after the line of yield expression).

def isprime(n):
    if n == 1:
        return False
    for x in range(2, n):
        if n % x == 0:
            return False
    else:
        return True

def primes(n = 1):
   while(True):
       if isprime(n): yield n
       n += 1 

for n in primes():
    if n > 100: break
    print(n)

In the above example if isprime(n) is true it will return the prime number. In the next iteration it will continue from the next line

n += 1  

function getBetween($string, $start = "", $end = ""){
    if (strpos($string, $start)) { // required if $start not exist in $string
        $startCharCount = strpos($string, $start) + strlen($start);
        $firstSubStr = substr($string, $startCharCount, strlen($string));
        $endCharCount = strpos($firstSubStr, $end);
        if ($endCharCount == 0) {
            $endCharCount = strlen($firstSubStr);
        }
        return substr($firstSubStr, 0, $endCharCount);
    } else {
        return '';
    }
}

Sample use:

echo getBetween("abc","a","c"); // returns: 'b'

echo getBetween("hello","h","o"); // returns: 'ell'

echo getBetween("World","a","r"); // returns: ''

If you have to deal with NTLM proxy authentication a good alternative is to use a configure a local proxy using CNTLM.

The credentials and domain are configured in /etc/cntlm.conf.

Afterwards you can just use you own proxy that handles all the NTLM stuff.

DesiredCapabilities capabilities = DesiredCapabilities.chrome();

Proxy proxy = new Proxy();
proxy.setHttpProxy("localhost:3128");
capabilities.setCapability(CapabilityType.PROXY, proxy);

driver = new ChromeDriver(capabilities);

ID is an attribute, you can set it with the attr function:

$(element).attr('id', 'newID');

I'm not sure what you mean about adding IDs since an element can only have one identifier and this identifier must be unique.

No, that's not quite right.

EAX is the full 32-bit value
AX is the lower 16-bits
AL is the lower 8 bits
AH is the bits 8 through 15 (zero-based)

So AX is composed of AH:AL halves, and is itself the low half of EAX. (The upper half of EAX isn't directly accessible as a 16-bit register; you can shift or rotate EAX if you want to get at it.)

For completeness, in addition to the above, which was based on a 32-bit CPU, 64-bit Intel/AMD CPUs have

RAX, which hold a 64-bit value, and where EAX is mapped to the lower 32 bits.

All of this also applies to EBX/RBX, ECX/RCX, and EDX/RDX. The other registers like EDI/RDI have a DI low 16-bit partial register, but no high-8 part, and the low-8 DIL is only accessible in 64-bit mode: Assembly registers in 64-bit architecture

Writing AL, AH, or AX merges into the full AX/EAX/RAX, leaving other bytes unmodified for historical reasons. (In 32 or 64-bit code, prefer a movzx eax, byte [mem] or movzx eax, word [mem] load if you don't specifically want this merging: Why doesn't GCC use partial registers?)

Writing EAX zero-extends into RAX. (Why do x86-64 instructions on 32-bit registers zero the upper part of the full 64-bit register?)

You can use Java Pluggable Annotation Processing API to write annotation processor which will be executed during the compilation process and will collect all annotated classes and build the index file for runtime use.

This is the fastest way possible to do annotated class discovery because you don't need to scan your classpath at runtime, which is usually very slow operation. Also this approach works with any classloader and not only with URLClassLoaders usually supported by runtime scanners.

The above mechanism is already implemented in ClassIndex library.

To use it annotate your custom annotation with @IndexAnnotated meta-annotation. This will create at compile time an index file: META-INF/annotations/com/test/YourCustomAnnotation listing all annotated classes. You can acccess the index at runtime by executing:

ClassIndex.getAnnotated(com.test.YourCustomAnnotation.class)

        img.getPixels(pixels, 0, img.getWidth(), 0, 0, img.getWidth(), img.getHeight());

        //Create a Bitmap of the appropriate format.
        Bitmap result = Bitmap.createBitmap(img.getWidth(), img.getHeight(), Bitmap.Config.ARGB_8888);

        //Set RGB pixels.
        result.setPixels(pixels, 0, result.getWidth(), 0, 0, result.getWidth(), result.getHeight());
        return result;
    }

When creating your conditional formatting, set the range to which it applies to what you want (the whole sheet), then enter a relative formula (remove the $ signs) as if you were only formatting the upper-left corner.

Excel will properly apply the formatting to the rest of the cells accordingly.

In this example, starting in B1, the left cell would be A1. Just use that--no advanced formula required.

If you're looking for something more advanced, you can play around with column(), row(), and indirect(...).
