Programs & Examples On #Crystal reports 2008

Choose Database | Set Datasource Location... Select the database node (yellow-ish cylinder) of the current connection, then select the database node of the desired connection (you may need to authenticate), then click Update.

You will need to do this for the 'Subreports' nodes as well.

FYI, you can also do individual tables by selecting each individually, then choosing Update.

It happen that after some time we need to run

 'php artisan passport:install --force 

again to generate a key this solved my problem ,

To answer you first question:
Yes, it means that 1 byte allocates for 1 character. Look at this example

SQL> conn / as sysdba
Connected.
SQL> create table test (id number(10), v_char varchar2(10));

Table created.

SQL> insert into test values(11111111111,'darshan');
insert into test values(11111111111,'darshan')
*
ERROR at line 1:
ORA-01438: value larger than specified precision allows for this column


SQL> insert into test values(11111,'darshandarsh');
insert into test values(11111,'darshandarsh')
*
ERROR at line 1:
ORA-12899: value too large for column "SYS"."TEST"."V_CHAR" (actual: 12,
maximum: 10)


SQL> insert into test values(111,'Darshan');

1 row created.

SQL> 

And to answer your next one: The difference between varchar2 and varchar :

1. VARCHAR can store up to 2000 bytes of characters while VARCHAR2 can store up to 4000 bytes of characters.
2. If we declare datatype as VARCHAR then it will occupy space for NULL values, In case of VARCHAR2 datatype it will not occupy any space.

Here's the most concise way I've found (using capybara 3.3.0 and chromium driver):

all('#id-of-select option')[1].select_option

will select the 2nd option. Increment the index as needed.

You can use 1 div inside that to "erase" the shadow:

.yourdiv{
    position:relative;
    width:400px;
    height:400px;
    left:10px;
    top:40px;
    background-color:white;
    box-shadow: 0px 0px 1px 0.5px #5F5F5F;

}
.erase{
    position:absolute;
    width:100%;
    top:50%;
    height:105%;
    transform:translate(0%,-50%);
    background-color:white;
}

You can play with "height:%;" and "width:%;" to erase what shadow you want.

http://example.com/ may resolve to a different VirtualHost than https://example.com/ (which, as the Host header is not sent, responds to the default for that IP), so the two are treated as separate domains and thus subject to crossdomain JS restrictions.

JSON callbacks may let you avoid this.

If you're interested in type guarding an what would otherwise be a string (which is how I came across this issue), this might work for you:

enum CurrencyCode {
  cad = "cad",
  eur = "eur",
  gbp = "gbp",
  jpy = "jpy",
  usd = "usd",
}

const createEnumChecker = <T extends string, TEnumValue extends string>(
  enumVariable: { [key in T]: TEnumValue }
) => {
  const enumValues = Object.values(enumVariable);
  return (value: string | number | boolean): value is TEnumValue =>
    enumValues.includes(value);
};

const isCurrencyCode = createEnumChecker(CurrencyCode);

const input: string = 'gbp';

let verifiedCurrencyCode: CurrencyCode | null = null;
// verifiedCurrencyCode = input;
// ^ TypeError: Type 'string' is not assignable to type 'CurrencyCode | null'.

if (isCurrencyCode(input)) {
  verifiedCurrencyCode = input; // No Type Error 
}

Solution is taken from this github issue discussing generic Enums

The long running most typical approach to this question is: Isolated Storage.

Serialize your control state to XML or some other format (especially easily if you're saving Dependency Properties with WPF), then save the file to the user's isolated storage.

If you do want to go the app setting route, I tried something similar at one point myself...though the below approach could easily be adapted to use Isolated Storage:

class SettingsManager
{
    public static void LoadSettings(FrameworkElement sender, Dictionary<FrameworkElement, DependencyProperty> savedElements)
    {
        EnsureProperties(sender, savedElements);
        foreach (FrameworkElement element in savedElements.Keys)
        {
            try
            {
                element.SetValue(savedElements[element], Properties.Settings.Default[sender.Name + "." + element.Name]);
            }
            catch (Exception ex) { }
        }
    }

    public static void SaveSettings(FrameworkElement sender, Dictionary<FrameworkElement, DependencyProperty> savedElements)
    {
        EnsureProperties(sender, savedElements);
        foreach (FrameworkElement element in savedElements.Keys)
        {
            Properties.Settings.Default[sender.Name + "." + element.Name] = element.GetValue(savedElements[element]);
        }
        Properties.Settings.Default.Save();
    }

    public static void EnsureProperties(FrameworkElement sender, Dictionary<FrameworkElement, DependencyProperty> savedElements)
    {
        foreach (FrameworkElement element in savedElements.Keys)
        {
            bool hasProperty =
                Properties.Settings.Default.Properties[sender.Name + "." + element.Name] != null;

            if (!hasProperty)
            {
                SettingsAttributeDictionary attributes = new SettingsAttributeDictionary();
                UserScopedSettingAttribute attribute = new UserScopedSettingAttribute();
                attributes.Add(attribute.GetType(), attribute);

                SettingsProperty property = new SettingsProperty(sender.Name + "." + element.Name,
                    savedElements[element].DefaultMetadata.DefaultValue.GetType(), Properties.Settings.Default.Providers["LocalFileSettingsProvider"], false, null, SettingsSerializeAs.String, attributes, true, true);
                Properties.Settings.Default.Properties.Add(property);
            }
        }
        Properties.Settings.Default.Reload();
    }
}

.....and....

  Dictionary<FrameworkElement, DependencyProperty> savedElements = new Dictionary<FrameworkElement, DependencyProperty>();

public Window_Load(object sender, EventArgs e) {
           savedElements.Add(firstNameText, TextBox.TextProperty);
                savedElements.Add(lastNameText, TextBox.TextProperty);

            SettingsManager.LoadSettings(this, savedElements);
}

private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
        {
            SettingsManager.SaveSettings(this, savedElements);
        }

In my case, I had this javascript on the form submit:

$('form').submit(function () {
    $('input').prop('disabled', true);
});

This was removing the hidden RequestVerificationToken from the form being submitted. I changed that to:

$('form').submit(function () {
    $('input[type=submit]').prop('disabled', true);
    $('input[type=text]').prop('readonly', true);
    $('input[type=password]').prop('readonly', true);
});

... and it worked fine.

Instead of using the body, using html worked for me:

html {
   min-height:100%;
   position: relative;
}

div {
   position: absolute;

   top: 0px;
   bottom: 0px;
   right: 0px;
   left: 0px;
}

From the working copy:

svn rm branches/features
svn commit -m "delete stale feature branch"

For the text color add:

android:textColor="<hex color>"

For the background color add:

android:background="<hex color>"

From API 21 you can use:

android:backgroundTint="<hex color>"
android:backgroundTintMode="<mode>"

Note: If you're going to work with android/java you really should learn how to google ;)
How to customize different buttons in Android

In classic mode IIS works h ISAPI extensions and ISAPI filters directly. And uses two pipe lines , one for native code and other for managed code. You can simply say that in Classic mode IIS 7.x works just as IIS 6 and you dont get extra benefits out of IIS 7.x features.

In integrated mode IIS and ASP.Net are tightly coupled rather then depending on just two DLLs on Asp.net as in case of classic mode.

I was used to Home/End getting me to the start and end of lines in Insert mode (from use in Windows and I think Linux), which Mac doesn't support. This is particularly annoying because when I'm using vim on a remote system, I also can't easily do it. After some painful trial and error, I came up with these .vimrc lines which do the same thing, but bound to Ctrl-A for the start of the line and Ctrl-D for the end of the line. (For some reason, Ctrl-E I guess is reserved or at least I couldn't figure a way to bind it.) Enjoy.

:imap <Char-1> <Char-15>:normal 0<Char-13>
:imap <Char-4> <Char-15>:normal $<Char-13>

There's a good chart here for the ASCII control character codes here for others as well:

http://www.physics.udel.edu/~watson/scen103/ascii.html

You can also do Ctrl-V + Ctrl- as well, but that doesn't paste as well to places like this.

Also when you call from http request it will work properly but when your try to call from net.tcp that time you get all this kind stuff

Nothing worked for me, even restarting a computer. I couldn't install an app on my device. But I solved this problem by myself:

Go to DDMS and choose connected device. Now try again!

You can use ancestor. I find that this is easier to read because the element you are actually selecting is at the end of the path.

//span[contains(text(),'someText')]/ancestor::div[contains(@class, 'measure-tab')]

You should use CSS to align the textbox. The reason your code above does not work is because by default a div's width is the same as the container it's in, therefore in your example it is pushed below.

The following would work.

<td  colspan="2" class="cell">
                <asp:Label ID="Label6" runat="server" Text="Label"></asp:Label>        
                <asp:TextBox ID="TextBox3" runat="server" CssClass="righttextbox"></asp:TextBox>       
</td>

In your CSS file:

.cell
{
text-align:left;
}

.righttextbox
{
float:right;
}

Well, why do you have %20 url-quoting escapes in a formatting string in first place? Ideally you'd do the interpolation formatting first:

formatting_template = 'Hello World%s'
text = '!'
full_string = formatting_template % text

Then you url quote it afterwards:

result = urllib.quote(full_string)

That is better because it would quote all url-quotable things in your string, including stuff that is in the text part.

Xcode 5 has iOS 6/7 Deltas which is specifically made to resolve this issue. In the storyboard, I moved my views 20 pixels down to look right on iOS 7 and in order to make it iOS 6 compatible, I changed Delta y to -20.

Since my storyboard is not using auto-layout, in order to resize the height of views properly on iOS 6 I had to set Delta height as well as Delta Y.

Best examples are provided in the below links, which you can refactor to meet your requirements.

Try running the following program. You just have to be sure your window has the focus when you hit Return--to ensure that it does, first click the button a couple of times until you see some output, then without clicking anywhere else hit Return.

import tkinter as tk

root = tk.Tk()
root.geometry("300x200")

def func(event):
    print("You hit return.")
root.bind('<Return>', func)

def onclick():
    print("You clicked the button")

button = tk.Button(root, text="click me", command=onclick)
button.pack()

root.mainloop()

Then you just have tweak things a little when making both the button click and hitting Return call the same function--because the command function needs to be a function that takes no arguments, whereas the bind function needs to be a function that takes one argument(the event object):

import tkinter as tk

root = tk.Tk()
root.geometry("300x200")

def func(event):
    print("You hit return.")

def onclick(event=None):
    print("You clicked the button")

root.bind('<Return>', onclick)

button = tk.Button(root, text="click me", command=onclick)
button.pack()

root.mainloop()

Or, you can just forgo using the button's command argument and instead use bind() to attach the onclick function to the button, which means the function needs to take one argument--just like with Return:

import tkinter as tk

root = tk.Tk()
root.geometry("300x200")

def func(event):
    print("You hit return.")

def onclick(event):
    print("You clicked the button")

root.bind('<Return>', onclick)

button = tk.Button(root, text="click me")
button.bind('<Button-1>', onclick)
button.pack()

root.mainloop()

Here it is in a class setting:

import tkinter as tk

class Application(tk.Frame):
    def __init__(self):
        self.root = tk.Tk()
        self.root.geometry("300x200")

        tk.Frame.__init__(self, self.root)
        self.create_widgets()

    def create_widgets(self):
        self.root.bind('<Return>', self.parse)
        self.grid()

        self.submit = tk.Button(self, text="Submit")
        self.submit.bind('<Button-1>', self.parse)
        self.submit.grid()

    def parse(self, event):
        print("You clicked?")

    def start(self):
        self.root.mainloop()


Application().start()

Abstract your initialization into a method, and call the method from mounted and wherever else you want.

new Vue({
  methods:{
    init(){
      //call API
      //Setup game
    }
  },
  mounted(){
    this.init()
  }
})

Then possibly have a button in your template to start over.

<button v-if="playerWon" @click="init">Play Again</button>

In this button, playerWon represents a boolean value in your data that you would set when the player wins the game so the button appears. You would set it back to false in init.

First you need to separate your class from the further extensions ex you cannot extend AddAddressComponent.defaultProps within the class instead move it outside.

I will also recommend you to read about the Constructor and React's lifecycle: see Component Specs and Lifecycle

Here is what you want:

import PropTypes from 'prop-types';

class AddAddressComponent extends React.Component {
  render() {
    let { provinceList, cityList } = this.props;
    if(cityList === undefined || provinceList === undefined){
      console.log('undefined props');
    }
  }
}

AddAddressComponent.contextTypes = {
  router: PropTypes.object.isRequired
};

AddAddressComponent.defaultProps = {
  cityList: [],
  provinceList: [],
};

AddAddressComponent.propTypes = {
  userInfo: PropTypes.object,
  cityList: PropTypes.array.isRequired,
  provinceList: PropTypes.array.isRequired,
}

export default AddAddressComponent;

So let's say you have a local branch foo, a remote called origin and a remote branch origin/master.

To push the contents of foo to origin/master, you first need to set its upstream:

git checkout foo
git branch -u origin/master

Then you can push to this branch using:

git push origin HEAD:master

In the last command you can add --force to replace the entire history of origin/master with that of foo.

Same as above. Use double quote to start the comment and without the closing quote.

Example:

set cul "Highlight current line

It seems that OpenQA, guys behind Selenium, have already addressed this problem. They defined some variables to explicitely match whitespaces. In my case, I need to use an XPATH similar to //td[text()="${nbsp}"].

I reproduced here the text from OpenQA concerning this issue (found here):

HTML automatically normalizes whitespace within elements, ignoring leading/trailing spaces and converting extra spaces, tabs and newlines into a single space. When Selenium reads text out of the page, it attempts to duplicate this behavior, so you can ignore all the tabs and newlines in your HTML and do assertions based on how the text looks in the browser when rendered. We do this by replacing all non-visible whitespace (including the non-breaking space " ") with a single space. All visible newlines (<br>, <p>, and <pre> formatted new lines) should be preserved.

We use the same normalization logic on the text of HTML Selenese test case tables. This has a number of advantages. First, you don't need to look at the HTML source of the page to figure out what your assertions should be; " " symbols are invisible to the end user, and so you shouldn't have to worry about them when writing Selenese tests. (You don't need to put " " markers in your test case to assertText on a field that contains " ".) You may also put extra newlines and spaces in your Selenese <td> tags; since we use the same normalization logic on the test case as we do on the text, we can ensure that assertions and the extracted text will match exactly.

This creates a bit of a problem on those rare occasions when you really want/need to insert extra whitespace in your test case. For example, you may need to type text in a field like this: "foo ". But if you simply write <td>foo </td> in your Selenese test case, we'll replace your extra spaces with just one space.

This problem has a simple workaround. We've defined a variable in Selenese, ${space}, whose value is a single space. You can use ${space} to insert a space that won't be automatically trimmed, like this: <td>foo${space}${space}${space}</td>. We've also included a variable ${nbsp}, that you can use to insert a non-breaking space.

Note that XPaths do not normalize whitespace the way we do. If you need to write an XPath like //div[text()="hello world"] but the HTML of the link is really "hello world", you'll need to insert a real " " into your Selenese test case to get it to match, like this: //div[text()="hello${nbsp}world"].

Using REQUIRES_NEW is only relevant when the method is invoked from a transactional context; when the method is invoked from a non-transactional context, it will behave exactly as REQUIRED - it will create a new transaction.

That does not mean that there will only be one single transaction for all your clients - each client will start from a non-transactional context, and as soon as the the request processing will hit a @Transactional, it will create a new transaction.

So, with that in mind, if using REQUIRES_NEW makes sense for the semantics of that operation - than I wouldn't worry about performance - this would textbook premature optimization - I would rather stress correctness and data integrity and worry about performance once performance metrics have been collected, and not before.

On rollback - using REQUIRES_NEW will force the start of a new transaction, and so an exception will rollback that transaction. If there is also another transaction that was executing as well - that will or will not be rolled back depending on if the exception bubbles up the stack or is caught - your choice, based on the specifics of the operations. Also, for a more in-depth discussion on transactional strategies and rollback, I would recommend: «Transaction strategies: Understanding transaction pitfalls», Mark Richards.

You can use the -f operator

$a = "{0:D}" -f (get-date)
$a = "{0:dddd}" -f (get-date)

Replacing image: ${DOCKER_REGISTRY}notificationsapi with image:notificationsapi or image: ${docker_registry}notificationsapi in docker-compose.yml did solves the issue

file with error

  version: '3.4'

services:
  notifications.api:
    image: ${DOCKER_REGISTRY}notificationsapi
    build:
      context: .
      dockerfile: ../Notifications.Api/Dockerfile

file without error

version: '3.4'

services:
 notifications.api:
    image: ${docker_registry}notificationsapi
    build:
      context: .
      dockerfile: ../Notifications.Api/Dockerfile

So i think error was due to non lower case letters it had

Swift 3,4:

2 useful conversions:

string(from: Date) // to convert from Date to a String
date(from: String) // to convert from String to Date

Usage: 1.

let date = Date() //gives today's date
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd.MM.yyyy"
let todaysDateInUKFormat = dateFormatter.string(from: date)

2.

 let someDateInString = "23.06.2017"
 var getDateFromString = dateFormatter.date(from: someDateInString)

Check your firewall. When you disable it, then you can connect. If you want/can't disable the firewall, add a rule for your remote connection.

Your logic condition is wrong. IIUC, what you want is:

import pyspark.sql.functions as f

df.filter((f.col('d')<5))\
    .filter(
        ((f.col('col1') != f.col('col3')) | 
         (f.col('col2') != f.col('col4')) & (f.col('col1') == f.col('col3')))
    )\
    .show()

I broke the filter() step into 2 calls for readability, but you could equivalently do it in one line.

Output:

+----+----+----+----+---+

An HttpOnly cookie means that it's not available to scripting languages like JavaScript. So in JavaScript, there's absolutely no API available to get/set the HttpOnly attribute of the cookie, as that would otherwise defeat the meaning of HttpOnly.

Just set it as such on the server side using whatever server side language the server side is using. If JavaScript is absolutely necessary for this, you could consider to just let it send some (ajax) request with e.g. some specific request parameter which triggers the server side language to create an HttpOnly cookie. But, that would still make it easy for hackers to change the HttpOnly by just XSS and still have access to the cookie via JS and thus make the HttpOnly on your cookie completely useless.

As stated by @Dugini, some config entries have been removed. Maximal:

webdriver.DesiredCapabilities.FIREFOX['proxy'] = {
    "httpProxy":PROXY,
    "ftpProxy":PROXY,
    "sslProxy":PROXY,
    "noProxy":[],
    "proxyType":"MANUAL"
 }

For Windows/WSL/Cygwin etc users:

Make sure that your line endings are standard Unix line feeds, i.e. \n (LF) only.

Using Windows line endings \r\n (CRLF) line endings will break the command line break.

This is because having \ at the end of a line with Windows line ending translates to \ \r \n.
As Mark correctly explains above:

The line-continuation will fail if you have whitespace after the backslash and before the newline.

This includes not just space () or tabs (\t) but also the carriage return (\r).

I had set:

log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.DatePattern='.'yyyy-MM-dd
# Archive log files (Keep one year of daily files)
log4j.appender.R.MaxBackupIndex=367

Like others before me, the DEBUG option showed me the error:

log4j:WARN No such property [maxBackupIndex] in org.apache.log4j.DailyRollingFileAppender.

Here is an idea I have not tried yet, suppose I set the DatePattern such that the files overwrite each other after the required time period. To retain a year's worth I could try setting:

log4j.appender.R.DatePattern='.'MM-dd

Would it work or would it cause an error ? Like that it will take a year to find out, I could try:

log4j.appender.R.DatePattern='.'dd

but it will still take a month to find out.

To list processes holding deleted files a linux system which has no lsof, here's my trick:

    pushd /proc ; for i in [1-9]* ; do ls -l $i/fd | grep "(deleted)" && (echo -n "used by: " ; ps -p $i | grep -v PID ; echo ) ; done ; popd

You can use exec for that:

>>> foo = "bar"
>>> exec(foo + " = 'something else'")
>>> print bar
something else

A stream is a continuous flow of liquid, air, or gas.

Java stream is a flow of data from a source into a destination. The source or destination can be a disk, memory, socket, or other programs. The data can be bytes, characters, or objects. The same applies for C# or C++ streams. A good metaphor for Java streams is water flowing from a tap into a bathtub and later into a drainage.

The data represents the static part of the stream; the read and write methods the dynamic part of the stream.

InputStream represents a flow of data from the source, the OutputStream represents a flow of data into the destination. Finally, InputStream and OutputStream are abstractions over low-level access to data, such as C file pointers.

What @Bogdan Maxim said. Or change to use InProc if you're not using an external sesssion state server.

<sessionState mode="InProc" timeout="20" cookieless="AutoDetect" />

Look here for more info on the SessionState directive.

puts or p is a good start to do that.

p "asd"       # => "asd"
puts "asd"    # => asd

here is more information about that: http://www.ruby-doc.org/core-1.9.3/ARGF.html

To add a very important note on what Mark S. has mentioned in his post. In the specific SQL Script that has been mentioned in the question you can NEVER mention two different file groups for storing your data rows and the index data structure.

The reason why is due to the fact that the index being created in this case is a clustered Index on your primary key column. The clustered index data and the data rows of your table can NEVER be on different file groups.

So in case you have two file groups on your database e.g. PRIMARY and SECONDARY then below mentioned script will store your row data and clustered index data both on PRIMARY file group itself even though I've mentioned a different file group ([SECONDARY]) for the table data. More interestingly the script runs successfully as well (when I was expecting it to give an error as I had given two different file groups :P). SQL Server does the trick behind the scene silently and smartly.

CREATE TABLE [dbo].[be_Categories](
    [CategoryID] [uniqueidentifier] ROWGUIDCOL  NOT NULL CONSTRAINT [DF_be_Categories_CategoryID]  DEFAULT (newid()),
    [CategoryName] [nvarchar](50) NULL,
    [Description] [nvarchar](200) NULL,
    [ParentID] [uniqueidentifier] NULL,
 CONSTRAINT [PK_be_Categories] PRIMARY KEY CLUSTERED 
(
    [CategoryID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [SECONDARY]
GO

NOTE: Your index can reside on a different file group ONLY if the index being created is non-clustered in nature.

The below script which creates a non-clustered index will get created on [SECONDARY] file group instead when the table data already resides on [PRIMARY] file group:

CREATE NONCLUSTERED INDEX [IX_Categories] ON [dbo].[be_Categories]
(
    [CategoryName] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [Secondary]
GO

You can get more information on how storing non-clustered indexes on a different file group can help your queries perform better. Here is one such link.

Simply use if statement

 if(!isset($_SESSION)) 
     { 
         session_start(); 
     }

or

check the session status with session_status that Returns the current session status and if current session is already working then return with nothing else if session not working start the session

session_status() === PHP_SESSION_ACTIVE ?: session_start();

When you are in the context of a trigger you have access to the logical table INSERTED which contains all the rows that have just been inserted to the table. You can build your insert to the other table based on a select from Inserted.

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|00D900",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(12, 18)
);

My idea:

public enum SomeKindOfEnum{
    ENUM_NAME("initialValue");

    private String value;

    SomeKindOfEnum(String value){
        this.value = value;
    }

    public boolean equalValue(String passedValue){
        return this.value.equals(passedValue);
    }
}

And if u want to check Value u write:

SomeKindOfEnum.ENUM_NAME.equalValue("initialValue")

Kinda looks nice for me :). Maybe somebody will find it useful.

Select the Body using chrome dev tools (Inspect ) and change in css overflow:visible,

If that doesn't work then check in below css file if html, body is set as overflow:hidden , change it as visible

Windows > Preferences > General > Appearance > Colors and Fonts

Then, to change Java editor font: Java > Java Editor Text Font > EDIT

There it is.

After have read all the above, I have found that there could be another reason for this.

In my case:

react-native-cli: 2.0.1

react-native: 0.60.4

and following structure:

First has to be noted that index.android is not been update in Android Studio when the build run by Metro builder( react-native run-android) so it has to be done manually. Also in Android studio does not "read" the

app.json(created by default together with index.js, that renamed index.android.js):

 {
    "name": "authApp",
    "displayName": "authApp"
 }

and so this like

(in my case)

import {authApp as appName} from './app.json';

cause the fact that android studio does not know what authApp refer to. I fix for the moment referring to the app name with its string name and not using that import from app.json:

AppRegistry.registerComponent('authApp', () => MyApp);

example of textarea for disable the resize option

<textarea CLASS="foo"></textarea>

<style>
textarea.foo
{
resize:none;
}

</style>

The program immediately closes because there's nothing stopping it from closing. Insert a breakpoint at return 0; or add Console.Read(); before return 0; to prevent the program from closing.

GIFImageView

public class GifImageView extends ImageView {

    Movie movie;
    InputStream inputStream;
    private long mMovieStart;

    public GifImageView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    public GifImageView(Context context) {
        super(context);
    }

    public GifImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
        setFocusable(true);
        inputStream = context.getResources()
                .openRawResource(R.drawable.thunder);
            byte[] array = streamToBytes(inputStream);
            movie = Movie.decodeByteArray(array, 0, array.length);

    }

    private byte[] streamToBytes(InputStream is) {
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(
                1024);
        byte[] buffer = new byte[1024];
        int len;
        try {
            while ((len = is.read(buffer)) >= 0) {
                byteArrayOutputStream.write(buffer, 0, len);
                return byteArrayOutputStream.toByteArray();
            }
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
        return null;
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        long now = SystemClock.uptimeMillis();
        if (mMovieStart == 0) { // first time
            mMovieStart = now;
        }
        if (movie != null) {
            int dur = movie.duration();
            if (dur == 0) {
                dur = 3000;
            }
            int relTime = (int) ((now - mMovieStart) % dur);
            movie.setTime(relTime);
            movie.draw(canvas, getWidth() - 200, getHeight() - 200);
            invalidate();
        }
    }

In Java File

public class MainActivity extends Activity {
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main); 
        GifImageView gifImageView = (GifImageView) findViewById(R.id.gifImageView1);
        if (Build.VERSION.SDK_INT >= 11) {
            gifImageView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
        }
    }
}

We need to use gifImageView.setLayerType(View.LAYER_TYPE_SOFTWARE, null); as when hardware accelerated enabled, GIF image not work on those device. Hardware accelerated is enabled on devices above(4.x).

To expand a bit more on what others are saying, if you wanted to use join to simply concatenate your two strings, you would do this:

strid = repr(595)
print ''.join([array.array('c', random.sample(string.ascii_letters, 20 - len(strid)))
    .tostring(), strid])

The default constructor has no arguments. You need to specify a constructor:

    public Friends( String firstName, String age) { ... }

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

This worked for me:

https://blog.dotkam.com/2007/04/10/mysql-reset-lost-root-password/

Step 1: Stop MySQL daemon if it is currently running

  ps -ef | grep mysql      - checks if mysql/mysqld is one of the running processes.

  pkill mysqld             - kills the daemon, if it is running.

Step 2: Run MySQL safe daemon with skipping grant tables

  mysqld_safe --skip-grant-tables &

  mysql -u root mysql

Step 3: Login to MySQL as root with no password

  mysql -u root mysql

Step 4: Run UPDATE query to reset the root password

  UPDATE user SET password=PASSWORD("value=42") WHERE user="root";
  FLUSH PRIVILEGES;

In MySQL 5.7, the 'password' field was removed, now the field name is 'authentication_string':

  UPDATE user SET authentication_string=PASSWORD("42") WHERE 
  user="root";
  FLUSH PRIVILEGES;

Step 5: Stop MySQL safe daemon

Step 6: Start MySQL daemon

I think this is very nice and short

<img src="imagenotfound.gif" alt="Image not found" onerror="this.src='imagefound.gif';" />

But, be careful. The user's browser will be stuck in an endless loop if the onerror image itself generates an error.

EDIT To avoid endless loop, remove the onerror from it at once.

<img src="imagenotfound.gif" alt="Image not found" onerror="this.onerror=null;this.src='imagefound.gif';" />

By calling this.onerror=null it will remove the onerror then try to get the alternate image.

NEW I would like to add a jQuery way, if this can help anyone.

<script>
$(document).ready(function()
{
    $(".backup_picture").on("error", function(){
        $(this).attr('src', './images/nopicture.png');
    });
});
</script>

<img class='backup_picture' src='./images/nonexistent_image_file.png' />

You simply need to add class='backup_picture' to any img tag that you want a backup picture to load if it tries to show a bad image.

Sadly I can't answer the other questions, don't have enough reputation, but I need to point something out that was VERY important for me, and I think it will help other people too.

Unsetting the variable is a nice way, unless you need the reference of the original array!

To make clear what I mean: If you have a function wich uses the reference of the array, for example a sorting function like

function special_sort_my_array(&$array)
{
    $temporary_list = create_assoziative_special_list_out_of_array($array);

    sort_my_list($temporary_list);

    unset($array);
    foreach($temporary_list as $k => $v)
    {
        $array[$k] = $v;
    }
}

it is not working! Be careful here, unset deletes the reference, so the variable $array is created again and filled correctly, but the values are not accessable from outside the function.

So if you have references, you need to use $array = array() instead of unset, even if it is less clean and understandable.

An alternative to:

scriptPath=$(dirname $0)

is:

scriptPath=${0%/*}

.. the advantage being not having the dependence on dirname, which is not a built-in command (and not always available in emulators)

@Martin Devillers solution works fine. For completeness, providing the steps below:

1. Put your wsdl to resource directory like : src/main/resource

2. In pom file, add both wsdlDirectory and wsdlLocation(don't miss / at the beginning of wsdlLocation), like below. While wsdlDirectory is used to generate code and wsdlLocation is used at runtime to create dynamic proxy.

   <wsdlDirectory>src/main/resources/mydir</wsdlDirectory>
   <wsdlLocation>/mydir/my.wsdl</wsdlLocation>
   

3. Then in your java code(with no-arg constructor):

   MyPort myPort = new MyPortService().getMyPort();
   

4. Here is the full code generation part in pom file, with fluent api in generated code.

Turns out it is possible to enter a host name directly into the playbook, so running the playbook with hosts: imac-2.local will work fine. But it's kind of clunky.

A better solution might be defining the playbook's hosts using a variable, then passing in a specific host address via --extra-vars:

# file: user.yml  (playbook)
---
- hosts: '{{ target }}'
  user: ...

Running the playbook:

ansible-playbook user.yml --extra-vars "target=imac-2.local"

If {{ target }} isn't defined, the playbook does nothing. A group from the hosts file can also be passed through if need be. Overall, this seems like a much safer way to construct a potentially destructive playbook.

Playbook targeting a single host:

$ ansible-playbook user.yml --extra-vars "target=imac-2.local" --list-hosts

playbook: user.yml

  play #1 (imac-2.local): host count=1
    imac-2.local

Playbook with a group of hosts:

$ ansible-playbook user.yml --extra-vars "target=office" --list-hosts

playbook: user.yml

  play #1 (office): host count=3
    imac-1.local
    imac-2.local
    imac-3.local

Forgetting to define hosts is safe!

$ ansible-playbook user.yml --list-hosts

playbook: user.yml

  play #1 ({{target}}): host count=0

Since in css3 one might set multiple background images setting "none" will only create a new layer and hide nothing.

I have not found a solution yet...

It's documented here.

The sort() method takes optional arguments for controlling the comparisons.

cmp specifies a custom comparison function of two arguments (list items) which should return a negative, zero or positive number depending on whether the first argument is considered smaller than, equal to, or larger than the second argument: cmp=lambda x,y: cmp(x.lower(), y.lower()). The default value is None.

You need to set a name to your Routes. Like this:

    Route::get('/','WelcomeController@home')->name('welcome.home');
    Route::post('/', array('as' => 'log_in', 'uses' => 'WelcomeController@log_in'))->name('welcome.log_in');
    Route::get('home', 'HomeController@index')->name('home.index');

I just put name on Routes that need this. In my case, to call from tag form at blade template. Like this:

<form action="{{ route('home.index') }}" >

Or, You can do this:

<form action="/" >

Anything in the public folder is accessible at the root path (/) so change your img tag to read:

<img src="/images/rss.jpg" alt="rss feed" />

If you wanted to use a rails tag, use this:

<%= image_tag("rss.jpg", :alt => "rss feed") %>

code {_x000D_
    background: black;_x000D_
    color: white;_x000D_
    display: inline-block;_x000D_
    vertical-align: middle;_x000D_
}

<p>Some text <code>A<br />B<br />C<br />D</code> continues afterward.</p>

Tested and works in Safari 5 and IE6+.

I used this for the same purpose and it worked:

  select * from INFORMATION_SCHEMA.COLUMNS
  where TABLE_CATALOG= 'theDatabase'
  and COLUMN_NAME like 'theCol%'

closest() only looks for parents, I'm guessing what you really want is .find()

$(this).closest('.row').children('.column').find('.inputQty').val();

No jQuery needed.

Some people say using onclick is bad practice...

This example uses pure browser javascript. By default, it appears that the click handler will evaluate before the navigation, so you can cancel the navigation and do your own if you wish.

<a id="myButton" href="http://google.com">Click me!</a>
<script>
    window.addEventListener("load", () => {
        document.querySelector("#myButton").addEventListener("click", e => {
            alert("Clicked!");
            // Can also cancel the event and manually navigate
            // e.preventDefault();
            // window.location = e.target.href;
        });
    });
</script>

The string class has a constructor that takes a NULL-terminated C-string:

char arr[ ] = "This is a test";

string str(arr);


//  You can also assign directly to a string.
str = "This is another string";

// or
str = arr;

I currently have a workaround functional (it passes my unit tests). It is a good solution to my opinion when you only want to add a limited number of fields from other models.

Am I missing something here ?

class UserProfileForm(ModelForm):
    def __init__(self, instance=None, *args, **kwargs):
        # Add these fields from the user object
        _fields = ('first_name', 'last_name', 'email',)
        # Retrieve initial (current) data from the user object
        _initial = model_to_dict(instance.user, _fields) if instance is not None else {}
        # Pass the initial data to the base
        super(UserProfileForm, self).__init__(initial=_initial, instance=instance, *args, **kwargs)
        # Retrieve the fields from the user model and update the fields with it
        self.fields.update(fields_for_model(User, _fields))

    class Meta:
        model = UserProfile
        exclude = ('user',)

    def save(self, *args, **kwargs):
        u = self.instance.user
        u.first_name = self.cleaned_data['first_name']
        u.last_name = self.cleaned_data['last_name']
        u.email = self.cleaned_data['email']
        u.save()
        profile = super(UserProfileForm, self).save(*args,**kwargs)
        return profile

Okay, Though I'm bit late :), Here is the another solution.

SELECT CAST(FLOOR(CAST(GETDATE() AS FLOAT)) as DATETIME)

Result

2008-09-22 00:00:00.000

And if you are using SQL Server 2012 and higher then you can use FORMAT() function like this -

SELECT FORMAT(GETDATE(), 'yyyy-MM-dd')

Objects aren't passed at all. By default, the argument is evaluated and its value is passed, by value, as the initial value of the parameter of the method you're calling. Now the important point is that the value is a reference for reference types - a way of getting to an object (or null). Changes to that object will be visible from the caller. However, changing the value of the parameter to refer to a different object will not be visible when you're using pass by value, which is the default for all types.

If you want to use pass-by-reference, you must use out or ref, whether the parameter type is a value type or a reference type. In that case, effectively the variable itself is passed by reference, so the parameter uses the same storage location as the argument - and changes to the parameter itself are seen by the caller.

So:

public void Foo(Image image)
{
    // This change won't be seen by the caller: it's changing the value
    // of the parameter.
    image = Image.FromStream(...);
}

public void Foo(ref Image image)
{
    // This change *will* be seen by the caller: it's changing the value
    // of the parameter, but we're using pass by reference
    image = Image.FromStream(...);
}

public void Foo(Image image)
{
    // This change *will* be seen by the caller: it's changing the data
    // within the object that the parameter value refers to.
    image.RotateFlip(...);
}

I have an article which goes into a lot more detail in this. Basically, "pass by reference" doesn't mean what you think it means.

Full credit to bchr02 for this answer. However, I had to modify it a bit to catch the scenario for lines that have */ (end of comment) followed by an empty line. The regex was matching the non empty line with */.

New: (^(\r\n|\n|\r)$)|(^(\r\n|\n|\r))|^\s*$/gm

All I did is add ^ as second character to signify the start of line.

I've had the same problem. It is just a batch-file, working when manually started, but not working as a scheduled task.

there were drive-letters in the batch-file like this:

put z:\folder\file.ext

seems like you should not use drive-letters, they are bound to the user, who created them - for me this little change made it work again:

put \\server\folder\file.ext

For some reason, none of previous answers worked in my case, so I'll post something that did the trick. There is a little jewel called RawCap that can capture localhost traffic on Windows. Advantages:

• only 17 kB!
• no external libraries needed
• extremely simple to use (just start it, choose the loopback interface and destination file and that's all)

After the traffic has been captured, you can open it and examine in Wireshark normally. The only disadvantage that I found is that you cannot set filters, i.e. you have to capture all localhost traffic which can be heavy. There is also one bug regarding Windows XP SP 3.

Few more advices:

• Wireshark wiki

For all users, I would recommend placing the following line in /etc/profile

export JAVA_HOME=$(readlink -f /usr/bin/javac | sed "s:/bin/javac::")

This will update dynamically and works well with the alternatives system. Do note though that the update will only take place in a new login shell.

To sum values in data.frame you first need to extract them as a vector.

There are several way to do it:

# $ operatior
x <- people$Weight
x
# [1] 65 70 64

Or using [, ] similar to matrix:

x <- people[, 'Weight']
x
# [1] 65 70 64

Once you have the vector you can use any vector-to-scalar function to aggregate the result:

sum(people[, 'Weight'])
# [1] 199

If you have NA values in your data, you should specify na.rm parameter:

sum(people[, 'Weight'], na.rm = TRUE)

None of the above approaches work in iOS 4.0

The pickerView's height is no longer re-sizable. There is a message which gets dumped to console if you attempt to change the frame of a picker in 4.0:

-[UIPickerView setFrame:]: invalid height value 66.0 pinned to 162.0 

I ended up doing something quite radical to get the effect of a smaller picker which works in both OS 3.xx and OS 4.0. I left the picker to be whatever size the SDK decides it should be and instead made a cut-through transparent window on my background image through which the picker becomes visible. Then simply placed the picker behind (Z Order wise) my background UIImageView so that only a part of the picker is visible which is dictated by the transparent window in my background.

Few arrays can also be iterated like this:

foreach($array1 as $key=>$val){ // Loop though one array
    $val2 = $array2[$key]; // Get the values from the other arrays
    $val3 = $array3[$key];
    $result[] = array( //Save result in third array
      'id' => $val,
      'quant' => $val2,
      'name' => $val3,
    );
  }

I ran into a similar situation with code that WAS working , then was not.

Turned while dragging / dropping code within a file, I moved an object into another set of braces. Took longer to figure out than I care to admit.

Bit once I move the code back into its proper place, the error resolved.

I believe for databases which support listagg function, you can do:

select id, issue, customfield, parentkey, listagg(stingvalue, ',') within group (order by id)
from jira.customfieldvalue
where customfield = 12534 and issue = 19602
group by id, issue, customfield, parentkey

For anyone that is working with a directory style like this:

project
    > src
        > pkgA     
        > pkgB
        ...
    > bin
        > pkgA
        > pkgB
        ...

The following worked very well for me. I made this myself, using the GNU make manual as my main reference; this, in particular, was extremely helpful for my last rule, which ended up being the most important one for me.

My Makefile:

PROG := sim
CC := g++
ODIR := bin
SDIR := src
MAIN_OBJ := main.o
MAIN := main.cpp
PKG_DIRS := $(shell ls $(SDIR))
CXXFLAGS = -std=c++11 -Wall $(addprefix -I$(SDIR)/,$(PKG_DIRS)) -I$(BOOST_ROOT)
FIND_SRC_FILES = $(wildcard $(SDIR)/$(pkg)/*.cpp) 
SRC_FILES = $(foreach pkg,$(PKG_DIRS),$(FIND_SRC_FILES)) 
OBJ_FILES = $(patsubst $(SDIR)/%,$(ODIR)/%,\
$(patsubst %.cpp,%.o,$(filter-out $(SDIR)/main/$(MAIN),$(SRC_FILES))))

vpath %.h $(addprefix $(SDIR)/,$(PKG_DIRS))
vpath %.cpp $(addprefix $(SDIR)/,$(PKG_DIRS)) 
vpath $(MAIN) $(addprefix $(SDIR)/,main)

# main target
#$(PROG) : all
$(PROG) : $(MAIN) $(OBJ_FILES) 
    $(CC) $(CXXFLAGS) -o $(PROG) $(SDIR)/main/$(MAIN) 

# debugging
all : ; $(info $$PKG_DIRS is [${PKG_DIRS}])@echo Hello world

%.o : %.cpp
    $(CC) $(CXXFLAGS) -c $< -o $@

# This one right here, folks. This is the one.
$(OBJ_FILES) : $(ODIR)/%.o : $(SDIR)/%.h
    $(CC) $(CXXFLAGS) -c $< -o $@

# for whatever reason, clean is not being called...
# any ideas why???
.PHONY: clean

clean :
    @echo Build done! Cleaning object files...
    @rm -r $(ODIR)/*/*.o

By using $(SDIR)/%.h as a prerequisite for $(ODIR)/%.o, this forced make to look in source-package directories for source code instead of looking in the same folder as the object file.

I hope this helps some people. Let me know if you see anything wrong with what I've provided.

BTW: As you may see from my last comment, clean is not being called and I am not sure why. Any ideas?

The stack pointer holds the address to the top of the stack. A stack allows functions to pass arguments stored on the stack to each other, and to create scoped variables. Scope in this context means that the variable is popped of the stack when the stack frame is gone, and/or when the function returns. Without a stack, you would need to use explicit memory addresses for everything. That would make it impossible (or at least severely difficult) to design high-level programming languages for the architecture. Also, each CPU mode usually have its own banked stack pointer. So when exceptions occur (interrupts for example), the exception handler routine can use its own stack without corrupting the user process.

All the answers given using LIKEare totally valid, but as all of them noted will be slow. So if you have a lot of queries and not too many changes in the list of keywords, it pays to build a structure that allows for faster querying.

Here are some ideas:

If all you are looking for is the letters a-z and you don't care about uppercase/lowercase, you can add columns containsA .. containsZ and prefill those columns:

UPDATE table
SET containsA = 'X' 
WHERE UPPER(your_field) Like '%A%';

(and so on for all the columns).

Then index the contains.. columns and your query would be

SELECT 
FROM your_table
WHERE containsA = 'X'
AND containsB = 'X'

This may be normalized in an "index table" iTable with the columns your_table_key, letter, index the letter-column and your query becomes something like

SELECT
FROM your_table 
WHERE <key> in (select a.key
    From iTable a join iTable b and a.key = b.key
    Where a.letter = 'a'
    AND b.letter = 'b');

All of these require some preprocessing (maybe in a trigger or so), but the queries should be a lot faster.

I required a specific colour, so filter didn't work for me.

Instead, I created a div, exploiting CSS multiple background images and the linear-gradient function (which creates an image itself). If you use the overlay blend mode, your actual image will be blended with the generated "gradient" image containing your desired colour (here, #BADA55)

.colored-image {_x000D_
        background-image: linear-gradient(to right, #BADA55, #BADA55), url("https://i.imgur.com/lYXT8R6.png");_x000D_
        background-blend-mode: overlay;_x000D_
        background-size: contain;_x000D_
        width: 200px;_x000D_
        height: 200px;        _x000D_
    }

<div class="colored-image"></div>

Yes, as was already noted by Jeffrey Bosboom (Sorry Jeffrey, I hadn't noticed your comment when I answered), there is such a function: Math.negateExact.

and

No, you probably shouldn't be using it. Not unless you need a method reference.

Check your servers error log, typically /var/log/apache2/error.log.

Something like this perhaps?

x<-rnorm(100000,mean=10, sd=2)
hist(x,breaks=150,xlim=c(0,20),freq=FALSE)
abline(v=10, lwd=5)
abline(v=c(4,6,8,12,14,16), lwd=3,lty=3)

To get Fiddler to capture traffic when you are debugging on local host, after you hit F5 to begin degugging change the address so that localhost has a "." after it.

For instance, you start debugging and the you have the following URL in the Address bar:

http://localhost:49573/Default.aspx

Change it to:

http://localhost.:49573/Default.aspx

Hit enter and Fidder will start picking up your traffic.

The browser is not adding any padding. Instead, letters (even uppercase letters) are generally considerably smaller in the vertical direction than the height of the font, not to mention the line height, which is typically by default about 1.2 times the font height (font size).

There is no general solution to this because fonts are different. Even for fixed font size, the height of a letter varies by font. And uppercase letters need not have the same height in a font.

Practical solutions can be found by experimentation, but they are unavoidably font-dependent. You will need to set the line height essentially smaller than the font size. The following seems to yield the desired result in different browsers on Windows, for the Arial font:

span.foo_x000D_
{_x000D_
  display: inline-block;_x000D_
  font-size: 50px;_x000D_
  background-color: green;_x000D_
  line-height: 0.75em;_x000D_
  font-family: Arial;_x000D_
}_x000D_
_x000D_
span.bar_x000D_
{_x000D_
  position: relative;_x000D_
  bottom: -0.02em;_x000D_
}

<span class=foo><span class=bar>BIG TEXT</span></span>

The nested span elements are used to displace the text vertically. Otherwise, the text sits on the baseline, and under the baseline, there is room reserved for descenders (as in letters j and y).

If you look closely (with zooming), you will notice that there is very small space above and below most letters here. I have set things so that the letter “G” fits in. It extends vertically a bit farther than other uppercase letters because that way the letters look similar in height. There are similar issues with other letters, like “O”. And you need to tune the settings if you’ll need the letter “Q” since it has a descender that extends a bit below the baseline (in Arial). And of course, if you’ll ever need “É”, or almost any diacritic mark, you’re in trouble.

You can to do it this way:

string Camnr = "", Klantnr = "", ... // or String.Empty

Or you could declare them all first and then in the next line use your way.

I have a bash script that calls a small python routine to display a message window. As I need to use killall to stop the python script I can't use the above method as it would then mean running killall python which could take out other python programmes so I use

pythonprog.py "$argument" & # The & returns control straight to the bash script so must be outside the backticks. The preview of this message is showing it without "`" either side of the command for some reason.

As long as the python script will run from the cli by name rather than python pythonprog.py this works within the script. If you need more than one argument just use a space between each one within the quotes.

To answer the second part of your question, you need to do things like

LV_DISPINFO dispinfo;  
dispinfo.item.pszText = LPTSTR((LPCTSTR)string);

because MS's LVITEM struct has an LPTSTR, i.e. a mutable T-string pointer, not an LPCTSTR. What you are doing is

1) convert string (a CString at a guess) into an LPCTSTR (which in practise means getting the address of its character buffer as a read-only pointer)

2) convert that read-only pointer into a writeable pointer by casting away its const-ness.

It depends what dispinfo is used for whether or not there is a chance that your ListView call will end up trying to write through that pszText. If it does, this is a potentially very bad thing: after all you were given a read-only pointer and then decided to treat it as writeable: maybe there is a reason it was read-only!

If it is a CString you are working with you have the option to use string.GetBuffer() -- that deliberately gives you a writeable LPTSTR. You then have to remember to call ReleaseBuffer() if the string does get changed. Or you can allocate a local temporary buffer and copy the string into there.

99% of the time this will be unnecessary and treating the LPCTSTR as an LPTSTR will work... but one day, when you least expect it...

Here is some code that show how it works.

class Test
{
    public static void main(String args[]) 
    { 
        System.out.println(Test.test()); 
    }

    public static String test()
    {
        try {
            System.out.println("try");
            throw new Exception();
        } catch(Exception e) {
            System.out.println("catch");
            return "return"; 
        } finally {  
            System.out.println("finally");
            return "return in finally"; 
        }
    }
}

The results is:

try
catch
finally
return in finally

There are quite a few options that can be used: (both tested).

Here are two ways.

header("Content-type: application/pdf");
header("Content-Disposition: inline; filename=filename.pdf");
@readfile('path\to\filename.pdf');

or: (note the escaped double-quotes). The same need to be use when assigning a name to it.

<?php

echo "<iframe src=\"file.pdf\" width=\"100%\" style=\"height:100%\"></iframe>";

?>

I.e.: name="myiframe" id="myiframe"

would need to be changed to:

name=\"myiframe\" id=\"myiframe\" inside PHP.

Be sure to have a look at: this answer on SO for more options on the subject.

Footnote: There are known issues when trying to view PDF files in Windows 8. Installing Adobe Acrobat Reader is a better method to view these types of documents if no browser plug-ins are installed.

the most obvious way to make foreach a possibility includes materializing the whole resultset in an array, which will probably kill you memory-wise, sooner or later. you'd need to turn to iterators to avoid that problem. see http://www.php.net/~helly/php/ext/spl/

Equally weighted children

To create a linear layout in which each child uses the same amount of space on the screen, set the android:layout_height of each view to "0dp" (for a vertical layout) or the android:layout_width of each view to "0dp" (for a horizontal layout). Then set the android:layout_weight of each view to "1".

In order for this to work in the LinearLayout view group the attribute values for android:layout_width and android:layout_height need to be equal to "match_parent"...

Too many big files all in one go. Windows barfs. Essentially the copying took too long because you asked too much of the computer and the file locking was locked too long and set a flag off, the flag is a semaphore error.

The computer stuffed itself and choked on it. I saw the RAM memory here get progressively filled with a Cache in RAM. Then when filled the subsystem ground to a halt with a semaphore error.

I have a workaround; copy or transfer fewer files not one humongous block. Break it down into sets of blocks and send across the files one at a time, maybe a few at a time, but not never the lot.

Fixed version in jsFiddle

Although this is a pretty old question I must say it is touching exactly the knowledge I was missing during my first steps in R - i.e. how to express data in my hand as an object in R or how to select from existing objects. It is not easy for an R novice to think "in an R box" from the very beginning.

So I myself started to use crutches below which helped me a lot to find out what object to use for what data, and basically to imagine real-world usage.

Though I not giving exact answers to the question the short text below might help the reader who just started with R and is asking similar questions.

• Atomic vector ... I called that "sequence" for myself, no direction, just sequence of same types. [ subsets.
• Vector ... the sequence with one direction from 2D, [ subsets.
• Matrix ... bunch of vectors with the same length forming rows or columns, [ subsets by rows and columns, or by sequence.
• Arrays ... layered matrices forming 3D
• Dataframe ... a 2D table like in excel, where I can sort, add or remove rows or columns or make arit. operations with them, only after some time I truly recognized that data frame is a clever implementation of list where I can subset using [ by rows and columns, but even using [[.
• List ... to help myself I thought about the list as of tree structure where [i] selects and returns whole branches and [[i]] returns item from the branch. And because it is tree like structure, you can even use an index sequence to address every single leaf on a very complex list using its [[index_vector]]. Lists can be simple or very complex and can mix together various types of objects into one.

So for lists you can end up with more ways how to select a leaf depending on situation like in the following example.

l <- list("aaa",5,list(1:3),LETTERS[1:4],matrix(1:9,3,3))
l[[c(5,4)]] # selects 4 from matrix using [[index_vector]] in list
l[[5]][4] # selects 4 from matrix using sequential index in matrix
l[[5]][1,2] # selects 4 from matrix using row and column in matrix

This way of thinking helped me a lot.

In my case it was because the filename was containing spaces. Solved it thanks to this documentation (which is unrelated to the problem):

from urllib.parse import unquote_plus
key_name = unquote_plus(event['Records'][0]['s3']['object']['key'])

You also need to upload urllib as a layer with corresponding version (if your lambda is Python 3.7 you have to package urllib in a python 3.7 environment).

The reason is that AWS transform ' ' into '+' (why...) which is really problematic...

This works for modern 'evergreen' browsers that support async/await and fetch.

This example is simplified, without error handling, to show the basic principals at work.

// This is a modern JS dependency fetcher - a "webpack" for the browser
const addDependentScripts = async function( scriptsToAdd ) {

  // Create an empty script element
  const s=document.createElement('script')

  // Fetch each script in turn, waiting until the source has arrived
  // before continuing to fetch the next.
  for ( var i = 0; i < scriptsToAdd.length; i++ ) {
    let r = await fetch( scriptsToAdd[i] )

    // Here we append the incoming javascript text to our script element.
    s.text += await r.text()
  }

  // Finally, add our new script element to the page. It's
  // during this operation that the new bundle of JS code 'goes live'.
  document.querySelector('body').appendChild(s)
}

// call our browser "webpack" bundler
addDependentScripts( [
  'https://code.jquery.com/jquery-3.5.1.slim.min.js',
  'https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/js/bootstrap.min.js'
] )

Here is the way I got that:

@Component
public class ApplicationStartup implements ApplicationListener<ApplicationReadyEvent> {

    /**
     * This event is executed as late as conceivably possible to indicate that
     * the application is ready to service requests.
     */

    @Autowired
    private MovieRepositoryImpl movieRepository;

    @Override
    public void onApplicationEvent(final ApplicationReadyEvent event) {
        seedData();
    }

    private void seedData() {
        movieRepository.save(new Movie("Example"));

        // ... add more code
    }

}

input() by default takes the input in form of strings.

if (0<= vote <=24):

vote takes a string input (suppose 4,5,etc) and becomes uncomparable.

The correct way is: vote = int(input("Enter your message")will convert the input to integer (4 to 4 or 5 to 5 depending on the input)

Dragon NaturallySpeaking seems to support MP3 input.

If you want an open source version (I think there are some Asterisk integration projects based on this one).

In case you want to cast to a class and not just a string:

YourClass model = await request.Content.ReadAsAsync<YourClass>();

The WordPress global variable $pagename should be available for you. I have just tried with the same setup you specified.

$pagename is defined in the file wp-includes/theme.php, inside the function get_page_template(), which is of course is called before your page theme files are parsed, so it is available at any point inside your templates for pages.

• Although it doesn't appear to be documented, the $pagename var is only set if you use permalinks. I guess this is because if you don't use them, WordPress doesn't need the page slug, so it doesn't set it up.

• $pagename is not set if you use the page as a static front page.

• This is the code inside /wp-includes/theme.php, which uses the solution you pointed out when $pagename can't be set:

--

if ( !$pagename && $id > 0 ) {
  // If a static page is set as the front page, $pagename will not be set. Retrieve it from the queried object
  $post = $wp_query->get_queried_object();
  $pagename = $post->post_name;
}

You can use these options as well, either use \footnotesize or \tiny. This would really help in fitting big tables.

\begin{table}[htbp]
\footnotesize
\caption{Information on making the table size small}
\label{table:table1}
\begin{tabular}{ll}
    \toprule
    S.No       & HMD           \\
    \midrule
    1          & HTC Vive \\
    2          & HTC Vive Pro   \\
    \bottomrule
\end{tabular}
\end{table}

Using a library called Pillow, you can make this into a function, for ease of use later in your program, and if you have to use it multiple times. The function simply takes in the path of an image and the coordinates of the pixel you want to "grab." It opens the image, converts it to an RGB color space, and returns the R, G, and B of the requested pixel.

from PIL import Image
def rgb_of_pixel(img_path, x, y):
    im = Image.open(img_path).convert('RGB')
    r, g, b = im.getpixel((x, y))
    a = (r, g, b)
    return a

*Note: I was not the original author of this code; it was left without an explanation. As it is fairly easy to explain, I am simply providing said explanation, just in case someone down the line does not understand it.

Please use

.FirstOrDefault()

because if in the first row of the result there is no info this instruction goes to the default info.

Though late answer, but would like to add that one way to get this

LayoutInflater layoutInflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view = layoutInflater.inflate(R.layout.mylayout, item );

where item is the parent layout where you want to add a child layout.

You can also use TimerTask for that.

Here is an method

private void setTimerTask() {
    long delay = 3000;
    long periodToRepeat = 60 * 1000; /* 1 mint */
    Timer timer = new Timer();
    timer.schedule(new TimerTask() {
        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                 //   do your stuff here.
                }
            });
        }
    }, 3000, 3000);
}

Here you go:

div{
    display: none;
}

document.querySelector("button").addEventListener("click", function(){
    document.querySelector("div").style.display = "block";
});

<div>blah blah blah</div>
<button>Show</button>

The main reason for primary and foreign keys is to enforce data consistency.

A primary key enforces the consistency of uniqueness of values over one or more columns. If an ID column has a primary key then it is impossible to have two rows with the same ID value. Without that primary key, many rows could have the same ID value and you wouldn't be able to distinguish between them based on the ID value alone.

A foreign key enforces the consistency of data that points elsewhere. It ensures that the data which is pointed to actually exists. In a typical parent-child relationship, a foreign key ensures that every child always points at a parent and that the parent actually exists. Without the foreign key you could have "orphaned" children that point at a parent that doesn't exist.

This runnable example shows how to use scrollIntoView() which is supported in all modern browsers: https://developer.mozilla.org/en-US/docs/Web/API/Element.scrollIntoView#Browser_Compatibility

$( "#yourid" )[0].scrollIntoView();

Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.

Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.

1. Go to your image in windows, then press ctrl + c OR Right click and Copy

2. Go to Your res Folder And choose One of the folders(eg. MDPI, HDPI..) and press ctrl + v OR right click it and Paste

This is purely because I had to spend time making/editing this when it should be widely available, so I'm providing it to everyone else.

The below script will Output a couple of CSV files to TEMP with the versions and vulnerability status of each machine in a selected (in the code) OU. You'll be able to remotely "security audit" an OU of machines.

Powershell 7.0 needed for the connection test line RSAT needed to get the AD module Visual Studio Code needed to get powershell 7.0 (on win7)

By the time you read this, the version list will probably be out of date within the file. Use this website https://docs.microsoft.com/en-us/dotnet/framework/migration-guide/versions-and-dependencies to add newer dotnet entries. It's just a bunch of key values in "DotNet4Builds"

If within CompromisedCheck.csv a machine shows as =0, it's had it's security turned off manually, and you should raise whether the supplier did it, or a suspect employee.

I hope this helps someone searching for it for their business.

tar.gz file is just a tar file that's been gzipped. Both tar and gzip are available for windows.

If you like GUIs (Graphical user interface), 7zip can pack with both tar and gzip.

If you are trying to do it on android 6 request the permission and use the code of the answer of this question

if (ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) { 
    ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, STORAGE_PERMISSION_RC); 
    return; 
} 

Once it is granted

@Override 
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == STORAGE_PERMISSION_RC) {
        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            //permission granted  start reading or writing database
        } else { 
            Toast.makeText(this, "No permission to read external storage.", Toast.LENGTH_SHORT).show();
        } 
    } 
} 

I had this problem using a local docker. The thing to do is check the logs of the containers its spins up to figure out what went wrong. For me it transpired that etcd had fallen over

   $ docker logs <etcdContainerId>
   <snip>
   2016-06-15 09:02:32.868569 C | etcdmain: listen tcp 127.0.0.1:7001: bind: address already in use

Aha! I'd been playing with Cassandra in a docker container and I'd forwarded all the ports since I wasn't sure which it needed exposed and 7001 is one of its ports. Stopping Cassandra, cleaning up the mess and restarting it fixed things.

Try dir /b, for bare format.

dir /? will show you documentation of what you can do with the dir command. Here is the output from my Windows 7 machine:

C:\>dir /?
Displays a list of files and subdirectories in a directory.

DIR [drive:][path][filename] [/A[[:]attributes]] [/B] [/C] [/D] [/L] [/N]
  [/O[[:]sortorder]] [/P] [/Q] [/R] [/S] [/T[[:]timefield]] [/W] [/X] [/4]

  [drive:][path][filename]
              Specifies drive, directory, and/or files to list.

  /A          Displays files with specified attributes.
  attributes   D  Directories                R  Read-only files
               H  Hidden files               A  Files ready for archiving
               S  System files               I  Not content indexed files
               L  Reparse Points             -  Prefix meaning not
  /B          Uses bare format (no heading information or summary).
  /C          Display the thousand separator in file sizes.  This is the
              default.  Use /-C to disable display of separator.
  /D          Same as wide but files are list sorted by column.
  /L          Uses lowercase.
  /N          New long list format where filenames are on the far right.
  /O          List by files in sorted order.
  sortorder    N  By name (alphabetic)       S  By size (smallest first)
               E  By extension (alphabetic)  D  By date/time (oldest first)
               G  Group directories first    -  Prefix to reverse order
  /P          Pauses after each screenful of information.
  /Q          Display the owner of the file.
  /R          Display alternate data streams of the file.
  /S          Displays files in specified directory and all subdirectories.
  /T          Controls which time field displayed or used for sorting
  timefield   C  Creation
              A  Last Access
              W  Last Written
  /W          Uses wide list format.
  /X          This displays the short names generated for non-8dot3 file
              names.  The format is that of /N with the short name inserted
              before the long name. If no short name is present, blanks are
              displayed in its place.
  /4          Displays four-digit years

Switches may be preset in the DIRCMD environment variable.  Override
preset switches by prefixing any switch with - (hyphen)--for example, /-W.

So by default you can open CMD and write

java -jar jenkins.war

But if your port 8080 is already is in use,so you have to change the Jenkins port number, so for that open Jenkins folder in Program File and open Jenkins.XML file and change the port number such as 8088

Now Open CMD and write

java -jar jenkins.war --httpPort=8088

Well, there are static constants of the exact integer values in the HttpURLConnection class

Hope this will help,

I like to simplify the code without using conditional operators in such cases:

TEMP=/mnt/silo/bin
[[ ${PATH} =~ ${TEMP} ]] || PATH=$PATH:$TEMP

All of the above failed for me. However, I was able to resolve the problem (after many hours of banging my head - Google, if you're listening, please consider fixing what I encountered below in the form of compiler errors, if possible)

You really have to be careful of what android attributes you add to your xml layout here (in this original question, it is called list_items.xml). For me, what was causing the problem was that I had switched from an EditText view to a TextView and had leftover attribute cruft from the change (in my case, inputType). The compiler didn't catch it and the clickability just failed when I went to run the app. Double check all of the attributes you have in your layout xml nodes.

I have done for

1. centerInParent

2. centerHorizontal

3. centerVertical

private void addOrRemoveProperty(View view, int property, boolean flag){
    RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) view.getLayoutParams();
    if(flag){
        layoutParams.addRule(property);
    }else {
        layoutParams.removeRule(property);
    }
    view.setLayoutParams(layoutParams);
}

How to call method:

centerInParent - true

addOrRemoveProperty(mView, RelativeLayout.CENTER_IN_PARENT, true);

centerInParent - false

addOrRemoveProperty(mView, RelativeLayout.CENTER_IN_PARENT, false);

centerHorizontal - true

addOrRemoveProperty(mView, RelativeLayout.CENTER_HORIZONTAL, true);

centerHorizontal - false

addOrRemoveProperty(mView, RelativeLayout.CENTER_HORIZONTAL, false);

centerVertical - true

addOrRemoveProperty(mView, RelativeLayout.CENTER_VERTICAL, true);

centerVertical - false

addOrRemoveProperty(mView, RelativeLayout.CENTER_VERTICAL, false);

Hope this would help you.

Here's a short and sweet JavaScript function to fetch the session ID:

function session_id() {
    return /SESS\w*ID=([^;]+)/i.test(document.cookie) ? RegExp.$1 : false;
}

Or if you prefer a variable, here's a simple one-liner:

var session_id = /SESS\w*ID=([^;]+)/i.test(document.cookie) ? RegExp.$1 : false;

Should match the session ID cookie for PHP, JSP, .NET, and I suppose various other server-side processors as well.

You can use FolderBrowserDialog instead of FileDialog and get the path from the OK result.

FolderBrowserDialog browser = new FolderBrowserDialog();
string tempPath ="";

if (browser.ShowDialog() == DialogResult.OK)
{
  tempPath  = browser.SelectedPath; // prints path
}

On the client side you can add and remove websites to be displayed in Compatibility View from Compatibility View Settings window of IE:

I think what the OP is looking for is a simple, windows-like solution.

here ya go:

https://www.macupdate.com/app/mac/14617/rcenvironment

Try this:

Create a model called Profile and reference the user with a OneToOneField and provide an option of related_name.

models.py

from django.db import models
from django.contrib.auth.models import *
from django.dispatch import receiver
from django.db.models.signals import post_save

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='user_profile')

    def __str__(self):
        return self.user.username

@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
    try:
        if created:
            Profile.objects.create(user=instance).save()
    except Exception as err:
        print('Error creating user profile!')

Now to directly access the profile using a User object you can use the related_name.

views.py

from django.http import HttpResponse

def home(request):
    profile = f'profile of {request.user.user_profile}'
    return HttpResponse(profile)

If youtube-dl is a terminal program, you can use the subprocess module to access the data you want.

FIXED SOLUTION FOR SWIFT 3+ (iOS 9, 10)

1- In info.plist set below property

2- Paste below code to Root controller , To

 private var isStatusBarHidden = true {
        didSet {
            setNeedsStatusBarAppearanceUpdate()
        }
    }

    override var prefersStatusBarHidden: Bool {
        return isStatusBarHidden
    }

You can call isStatusBarHidden = true and isStatusBarHidden = false where you want to hide/show status bar

Add:

• DELIMITER at the beginning and end of the SP.
• DROP PROCEDURE IF EXISTS validar_egreso; at the beginning
• When calling the SP, use @variableName.

This works for me. (I modified some part of your script so ANYONE can run it with out having your tables).

DROP PROCEDURE IF EXISTS `validar_egreso`;

DELIMITER $$

CREATE DEFINER='root'@'localhost' PROCEDURE `validar_egreso` (
    IN codigo_producto VARCHAR(100),
    IN cantidad INT,
    OUT valido INT(11)
)
BEGIN

    DECLARE resta INT;
    SET resta = 0;

    SELECT (codigo_producto - cantidad) INTO resta;

    IF(resta > 1) THEN
       SET valido = 1;
    ELSE
       SET valido = -1;
    END IF;

    SELECT valido;
END $$

DELIMITER ;

-- execute the stored procedure
CALL validar_egreso(4, 1, @val);

-- display the result
select @val;

Which objects are you using? Just tried that with a sample class and it worked fine:

class MyClass:
  i = 123456
  def f(self):
    return "hello world"

b = MyClass()
b.c = MyClass()
setattr(b.c, 'test', 123)
b.c.test

And I got 123 as the answer.

The only situation where I see this failing is if you're trying a setattr on a builtin object.

Update: From the comment this is a repetition of: Why can't you add attributes to object in python?

SELECT * 
FROM tbl 
WHERE myDate BETWEEN #date one# AND #date two#;

You can type "this." and wait a second, a popup with methods and properties will display.

Not a shortcut, but it works for me.

PS: if you are in a static method, type the class name.

Recursion means a function calls repeatedly

It uses system stack to accomplish it's task. As stack uses LIFO approach and when a function is called the controlled is moved to where function is defined which has it is stored in memory with some address, this address is stored in stack

Secondly, it reduces a time complexity of a program.

Though bit off-topic,a bit related. Must read. : Recursion vs Iteration

I would give a badly written query and ask them how they would go about performance tuning it.

I would ask about set theory. If you don't understand operating in sets, you can't effectively query a relational database.

I would give them some cursor examples and ask how they would rewrite them to make them set-based.

If the job involved imports and exports I would ask questions about SSIS (or other tools involved in doing this used by other datbases). If it involved writing reports, I would want to know that they understand aggregates and grouping (As well as Crystal Reports or SSRS or whatever ereporting tool you use).

I would ask the difference in results between these three queries:

select  a.field1
        , a.field2
        , b.field3
from table1 a
join table2 b
    on a.id = b.id
where a.field5 = 'test'
    and b.field3 = 1

select  a.field1
        , a.field2
        , b.field3
from table1 a
left join table2 b
    on a.id = b.id
where a.field5 = 'test'
    and b.field3 = 1

select  a.field1
        , a.field2
        , b.field3
from table1 a
left join table2 b
    on a.id = b.id and b.field3 = 1
where a.field5 = 'test'

For template, you can use

{% firstof request.user.get_full_name request.user.username %}

firstof will return the first one if not null else the second one

Similar to the top answer, we were getting this incredibly unhelpful exception because of a missing IIS CORS module. It was the exact same error with Error Code (0x8007000d) and Config Source (-1: 0:), but installing the URL Rewriting module didn't fix it.

We had recently updated the web.config to enable CORS for some developers that needed it, but did not expect it would be required for all developers to install the IIS CORS module. Unfortunately it looks like it is required.

To fix it, install the IIS CORS module from here.

I know it's a little late for an answer, but I've created a polyfill for the .live() method. I've tested it in jQuery 1.11, and it seems to work pretty well. I know that we're supposed to implement the .on() method wherever possible, but in big projects, where it's not possible to convert all .live() calls to the equivalent .on() calls for whatever reason, the following might work:

if(jQuery && !jQuery.fn.live) {
    jQuery.fn.live = function(evt, func) {
        $('body').on(evt, this.selector, func);
    }
}

Just include it after you load jQuery and before you call live().

you can convert a string to array with str_split and use foreach

$chars = str_split($str);
foreach($chars as $char){
    // your code
}

If you can afford to tie yourself to just Lollipop and later, this seems to do the trick:

import android.transition.Slide;
import android.util.Log;
import android.view.Gravity;
.
.
.
f = new MyFragment();
f.setEnterTransition(new Slide(Gravity.END));
f.setExitTransition(new Slide(Gravity.START));
getFragmentManager()
    .beginTransaction()
    .replace(R.id.content, f, FRAG_TAG)  // FRAG_TAG is the tag for your fragment
    .commit();

Kotlin version:

f = MyFragment().apply {
    enterTransition = Slide(Gravity.END)
    exitTransition = Slide(Gravity.START)
}
fragmentManager
    .beginTransaction()
    .replace(R.id.content, f, FRAG_TAG)  // FRAG_TAG is the tag for your fragment
    .commit();

Hope this helps.

I needed this same solution, but if you use the native ListObject.Add() method then you avoid the risk of clashing with any data immediately below the table. The below routine checks the last row of the table, and adds the data in there if it's blank; otherwise it adds a new row to the end of the table:

Sub AddDataRow(tableName As String, values() As Variant)
    Dim sheet As Worksheet
    Dim table As ListObject
    Dim col As Integer
    Dim lastRow As Range

    Set sheet = ActiveWorkbook.Worksheets("Sheet1")
    Set table = sheet.ListObjects.Item(tableName)

    'First check if the last row is empty; if not, add a row
    If table.ListRows.Count > 0 Then
        Set lastRow = table.ListRows(table.ListRows.Count).Range
        For col = 1 To lastRow.Columns.Count
            If Trim(CStr(lastRow.Cells(1, col).Value)) <> "" Then
                table.ListRows.Add
                Exit For
            End If
        Next col
    Else
        table.ListRows.Add
    End If

    'Iterate through the last row and populate it with the entries from values()
    Set lastRow = table.ListRows(table.ListRows.Count).Range
    For col = 1 To lastRow.Columns.Count
        If col <= UBound(values) + 1 Then lastRow.Cells(1, col) = values(col - 1)
    Next col
End Sub

To call the function, pass the name of the table and an array of values, one value per column. You can get / set the name of the table from the Design tab of the ribbon, in Excel 2013 at least:

Example code for a table with three columns:

Dim x(2)
x(0) = 1
x(1) = "apple"
x(2) = 2
AddDataRow "Table1", x

For Node.js there is Nodeclipse 0.2 with some bug fixes for chromedevtools

give the user $whoami to create somethin in those folder

sudo chown -R user /Library/Ruby/Gems/2.0.0

Something like this?

for i in xrange( someBigNumber ):
    try:
        doSomethingThatMightFail()
    except SomeException, e:
        continue
    doSomethingWhenNothingFailed()

You have to write as

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

Make sure you have jstl-1.0 & standard.jar BOTH files are placed in a classpath

the window.onload event will fire when everything is loaded, including images etc.

You would want to check the DOM ready status if you wanted your js code to execute as early as possible, but you still need to access DOM elements.

If you have the freedom to choose the hostname, then you can just add your host to a dynanmic DNS service, like dyndns.org. Then you can rely on the iPad's normal resolution mechanisms to resolve the address.

I know this was posted a long while ago, and it has been marked answered, but to me, the selected answer was not answering the question I thought the user was posing. It seemed to me he was looking for the approach one can take in ASP .Net that corresponds to his inline data binding previously performed in php.

Here was his php:

<p>Here is the username: <?php echo GetUserName(); ?></p>

Here is what one would do in ASP .Net:

<p>Here is the username: <%= GetUserName() %></p>

I came up with such solution, works great for me:

msbuild /t:ResolveReferences;_WPPCopyWebApplication /p:BuildingProject=true;OutDir=C:\Temp\build\ Test.csproj

The secret sauce is _WPPCopyWebApplication target.

--force option worked for me I used git push origin master --force

Unfortunately DEBUG is overloaded heavily. For instance, it's recommended to always generate and save a pdb file for RELEASE builds. Which means one of the -Zx flags, and -DEBUG linker option. While _DEBUG relates to special debug versions of runtime library such as calls to malloc and free. Then NDEBUG will disable assertions.

If you are using Bootstrap 3.3.x then use this code (you need to add class name carousel-fade to your carousel).

.carousel-fade .carousel-inner .item {
  -webkit-transition-property: opacity;
          transition-property: opacity;
}
.carousel-fade .carousel-inner .item,
.carousel-fade .carousel-inner .active.left,
.carousel-fade .carousel-inner .active.right {
  opacity: 0;
}
.carousel-fade .carousel-inner .active,
.carousel-fade .carousel-inner .next.left,
.carousel-fade .carousel-inner .prev.right {
  opacity: 1;
}
.carousel-fade .carousel-inner .next,
.carousel-fade .carousel-inner .prev,
.carousel-fade .carousel-inner .active.left,
.carousel-fade .carousel-inner .active.right {
  left: 0;
  -webkit-transform: translate3d(0, 0, 0);
          transform: translate3d(0, 0, 0);
}
.carousel-fade .carousel-control {
  z-index: 2;
}

To loop over the key/values, use a for in loop:

for (let key in myDictionary) {
    let value = myDictionary[key];
    // Use `key` and `value`
}

In Python, you can copy the files using

• shutil module
• os module
• subprocess module

import os
import shutil
import subprocess

1) Copying files using shutil module

shutil.copyfile signature

shutil.copyfile(src_file, dest_file, *, follow_symlinks=True)

# example    
shutil.copyfile('source.txt', 'destination.txt')

shutil.copy signature

shutil.copy(src_file, dest_file, *, follow_symlinks=True)

# example
shutil.copy('source.txt', 'destination.txt')

shutil.copy2 signature

shutil.copy2(src_file, dest_file, *, follow_symlinks=True)

# example
shutil.copy2('source.txt', 'destination.txt')  

shutil.copyfileobj signature

shutil.copyfileobj(src_file_object, dest_file_object[, length])

# example
file_src = 'source.txt'  
f_src = open(file_src, 'rb')

file_dest = 'destination.txt'  
f_dest = open(file_dest, 'wb')

shutil.copyfileobj(f_src, f_dest)  

2) Copying files using os module

os.popen signature

os.popen(cmd[, mode[, bufsize]])

# example
# In Unix/Linux
os.popen('cp source.txt destination.txt') 

# In Windows
os.popen('copy source.txt destination.txt')

os.system signature

os.system(command)


# In Linux/Unix
os.system('cp source.txt destination.txt')  

# In Windows
os.system('copy source.txt destination.txt')

3) Copying files using subprocess module

subprocess.call signature

subprocess.call(args, *, stdin=None, stdout=None, stderr=None, shell=False)

# example (WARNING: setting `shell=True` might be a security-risk)
# In Linux/Unix
status = subprocess.call('cp source.txt destination.txt', shell=True) 

# In Windows
status = subprocess.call('copy source.txt destination.txt', shell=True)

subprocess.check_output signature

subprocess.check_output(args, *, stdin=None, stderr=None, shell=False, universal_newlines=False)

# example (WARNING: setting `shell=True` might be a security-risk)
# In Linux/Unix
status = subprocess.check_output('cp source.txt destination.txt', shell=True)

# In Windows
status = subprocess.check_output('copy source.txt destination.txt', shell=True)

This can be achieved with the writing-mode property. If you set an element's writing-mode to a vertical writing mode, such as vertical-lr, its descendants' percentage values for padding and margin, in both dimensions, become relative to height instead of width.

From the spec:

. . . percentages on the margin and padding properties, which are always calculated with respect to the containing block width in CSS2.1, are calculated with respect to the inline size of the containing block in CSS3.

The definition of inline size:

A measurement in the inline dimension: refers to the physical width (horizontal dimension) in horizontal writing modes, and to the physical height (vertical dimension) in vertical writing modes.

Example, with a resizable element, where horizontal margins are relative to width and vertical margins are relative to height.

.resize {_x000D_
  width: 400px;_x000D_
  height: 200px;_x000D_
  resize: both;_x000D_
  overflow: hidden;_x000D_
}_x000D_
_x000D_
.outer {_x000D_
  height: 100%;_x000D_
  background-color: red;_x000D_
}_x000D_
_x000D_
.middle {_x000D_
  writing-mode: vertical-lr;_x000D_
  margin: 0 10%;_x000D_
  width: 80%;_x000D_
  height: 100%;_x000D_
  background-color: yellow;_x000D_
}_x000D_
_x000D_
.inner {_x000D_
  writing-mode: horizontal-tb;_x000D_
  margin: 10% 0;_x000D_
  width: 100%;_x000D_
  height: 80%;_x000D_
  background-color: blue;_x000D_
}

<div class="resize">_x000D_
  <div class="outer">_x000D_
    <div class="middle">_x000D_
      <div class="inner"></div>_x000D_
    </div>_x000D_
  </div>_x000D_
</div>

Using a vertical writing mode can be particularly useful in circumstances where you want the aspect ratio of an element to remain constant, but want its size to scale in correlation to its height instead of width.

if it is window7(like mine), without administrative rights cannot write a file at C: drive

just give another folder in log4j.properties file

Set the name of the file

log4j.appender.FILE.File=C:\server\log.out you can see with notepad++

This downloaded the entire website for me:

wget --no-clobber --convert-links --random-wait -r -p -E -e robots=off -U mozilla http://site/path/

If you are adding it as a VM argument, make sure you prefix it with -D:

-Djava.library.path=blahblahblah...

I think the easiest way to make it done is :

std::vector<std::vector<int>>v(10,std::vector<int>(11,100));

10 is the size of the outer or global vector, which is the main one, and 11 is the size of inner vector of type int, and initial values are initialized to 100! That's my first help on stack, i think it helps someone.

If you can't follow Max's suggestion of installing Blat (or any other utility) on your server, then perhaps your server already has software installed that can send emails.

I know that both Oracle and SqlServer have the capability to send email. You might have to work with your DBA to get that feature enabled and/or get the privilege to use it. Of course I can see how that might present its own set of problems and red tape. Assuming you can access the feature, it is fairly simple to have a batch file login to a database and send mail.

A batch file can easily run a VBScript via CSCRIPT. A quick google search finds many links showing how to send email with VBScript. The first one I happened to look at was http://www.activexperts.com/activmonitor/windowsmanagement/adminscripts/enterprise/mail/. It looks straight forward.

I use open query to perform this task like so:

select top 1 *
INTO [DATABASE_TO_INSERT_INTO].[dbo].[TABLE_TO_SELECT_INTO]
from openquery(
    [LINKED_SERVER_NAME],
    'select * from [DATABASE_ON_LINKED_SERVER].[dbo].[TABLE_TO_SELECT_FROM]'
)

The example above uses open query to select data from a database on a linked server into a database of your choosing.

Note: For completeness of reference, you may perform a simple select like so:

select top 1 * from openquery(
    [LINKED_SERVER_NAME],
    'select * from [DATABASE_ON_LINKED_SERVER].[dbo].[TABLE_TO_SELECT_FROM]'
)

To differentiate between scroll up/down in jQuery, you could use:

var mousewheelevt = (/Firefox/i.test(navigator.userAgent)) ? "DOMMouseScroll" : "mousewheel" //FF doesn't recognize mousewheel as of FF3.x
$('#yourDiv').bind(mousewheelevt, function(e){

    var evt = window.event || e //equalize event object     
    evt = evt.originalEvent ? evt.originalEvent : evt; //convert to originalEvent if possible               
    var delta = evt.detail ? evt.detail*(-40) : evt.wheelDelta //check for detail first, because it is used by Opera and FF

    if(delta > 0) {
        //scroll up
    }
    else{
        //scroll down
    }   
});

This method also works in divs that have overflow:hidden.

I successfully tested it in FireFox, IE and Chrome.

Try this Javascript (jquery) code. Its an ajax request to an external URL. Use the callback function to fire any code:

<script type="text/javascript">
$(function() {
  $('form').submit(function(){
    $.post('http://example.com/upload', function() {
      window.location = 'http://google.com';
    });
    return false;
  });
});
</script>

Using javascript, you can set tooltips for all the images on the page.

<!DOCTYPE html>
<html>
    <body>
    <img src="http://sushmareddy.byethost7.com/dist/img/buffet.png" alt="Food">
    <img src="http://sushmareddy.byethost7.com/dist/img/uthappizza.png" alt="Pizza">
     <script>
     //image objects
     var imageEls = document.getElementsByTagName("img");
     //Iterating
     for(var i=0;i<imageEls.length;i++){
        imageEls[i].title=imageEls[i].alt;
        //OR
        //imageEls[i].title="Title of your choice";
     }
        </script>
    </body>
</html>

You can just do:

df[sorted(df.columns)]

Edit: Shorter is

df[sorted(df)]

Convert hex to binary

I have ABC123EFFF.

I want to have 001010101111000001001000111110111111111111 (i.e. binary repr. with, say, 42 digits and leading zeroes).

Short answer:

The new f-strings in Python 3.6 allow you to do this using very terse syntax:

>>> f'{0xABC123EFFF:0>42b}'
'001010101111000001001000111110111111111111'

or to break that up with the semantics:

>>> number, pad, rjust, size, kind = 0xABC123EFFF, '0', '>', 42, 'b'
>>> f'{number:{pad}{rjust}{size}{kind}}'
'001010101111000001001000111110111111111111'

Long answer:

What you are actually saying is that you have a value in a hexadecimal representation, and you want to represent an equivalent value in binary.

The value of equivalence is an integer. But you may begin with a string, and to view in binary, you must end with a string.

Convert hex to binary, 42 digits and leading zeros?

We have several direct ways to accomplish this goal, without hacks using slices.

First, before we can do any binary manipulation at all, convert to int (I presume this is in a string format, not as a literal):

>>> integer = int('ABC123EFFF', 16)
>>> integer
737679765503

alternatively we could use an integer literal as expressed in hexadecimal form:

>>> integer = 0xABC123EFFF
>>> integer
737679765503

Now we need to express our integer in a binary representation.

Use the builtin function, format

Then pass to format:

>>> format(integer, '0>42b')
'001010101111000001001000111110111111111111'

This uses the formatting specification's mini-language.

To break that down, here's the grammar form of it:

[[fill]align][sign][#][0][width][,][.precision][type]

To make that into a specification for our needs, we just exclude the things we don't need:

>>> spec = '{fill}{align}{width}{type}'.format(fill='0', align='>', width=42, type='b')
>>> spec
'0>42b'

and just pass that to format

>>> bin_representation = format(integer, spec)
>>> bin_representation
'001010101111000001001000111110111111111111'
>>> print(bin_representation)
001010101111000001001000111110111111111111

String Formatting (Templating) with str.format

We can use that in a string using str.format method:

>>> 'here is the binary form: {0:{spec}}'.format(integer, spec=spec)
'here is the binary form: 001010101111000001001000111110111111111111'

Or just put the spec directly in the original string:

>>> 'here is the binary form: {0:0>42b}'.format(integer)
'here is the binary form: 001010101111000001001000111110111111111111'

String Formatting with the new f-strings

Let's demonstrate the new f-strings. They use the same mini-language formatting rules:

>>> integer = 0xABC123EFFF
>>> length = 42
>>> f'{integer:0>{length}b}'
'001010101111000001001000111110111111111111'

Now let's put this functionality into a function to encourage reusability:

def bin_format(integer, length):
    return f'{integer:0>{length}b}'

And now:

>>> bin_format(0xABC123EFFF, 42)
'001010101111000001001000111110111111111111'    

Aside

If you actually just wanted to encode the data as a string of bytes in memory or on disk, you can use the int.to_bytes method, which is only available in Python 3:

>>> help(int.to_bytes)
to_bytes(...)
    int.to_bytes(length, byteorder, *, signed=False) -> bytes
...

And since 42 bits divided by 8 bits per byte equals 6 bytes:

>>> integer.to_bytes(6, 'big')
b'\x00\xab\xc1#\xef\xff'

Currently my build is working. Here you are the steps I tried until it finally worked:

1. Search in the whole project the word CommonCrypto.
2. If you have a Pod containing that header import, remove this Pod from the Podfile and perform a pod install.
3. Clean and build the project.
4. Add again the Pod to the Podfile and perform a pod install.
5. Clean and build the project again using a real device if possible.

And If you don't have that Pod, maybe you can try by making the same steps with some old Pod that you may encounter in your project.

Added information: also If you have some code error inside a Pod, first you need to solve that code problem and then try to compile again the project.

I'm going to copy the changes made in my project.pbxproj. I know it's not very helpful but it's the only thing that have changed in the git difference commit:

Removed: BDC9821B1E9BD1B600ADE0EF /* (null) in Sources */ = {isa = PBXBuildFile; };
Added:   BDC9821B1E9BD1B600ADE0EF /* BuildFile in Sources */ = {isa = PBXBuildFile; };

I hope this can help,

Regards.

Here's a solution that may work better in the case you are referencing objWorksheet.UsedRange.

Excel.Worksheet mySheet = ...(load a workbook, etc);
Excel.Range myRange = mySheet.UsedRange;
var values = (myRange.Value as Object[,]);
int rowNumber = 3, columnNumber = 5;
string cellValue = Convert.ToString(values[rowNumber, columnNumber]);

I prefer to solve this in the classic way, creating a new array of my desired data type:

List<MyNewType> newArray = new ArrayList<>();
myOldArray.forEach(info -> newArray.add(objectMapper.convertValue(info, MyNewType.class)));

For OSX, you can go to your user's $HOME (probably /Users/yourname/) and, if it doesn't already exist, create an .npmrc file (a file that npm uses for user configuration), and create a directory for your npm packages to be installed in (e.g., /Users/yourname/npm). In that .npmrc file, set "prefix" to your new npm directory, which will be where "globally" installed npm packages will be installed; these "global" packages will, obviously, be available only to your user account.

In .npmrc:

prefix=${HOME}/npm

Then run this command from the command line:

npm config ls -l

It should give output on both your own local configuration and the global npm configuration, and you should see your local prefix configuration reflected, probably near the top of the long list of output.

For security, I recommend this approach to configuring your user account's npm behavior over chown-ing your /usr/local folders, which I've seen recommended elsewhere.

Try this.

No need for jQuery. And it isn't necessary to open a new window. Protocols which doesn't return HTTP data to the browser (mailto:, irc://, magnet:, ftp:// (<- it depends how it is implemented, normally the browser has an FTP client built in)) can be queried in the same window without losing the current content. In your case:

function redirect()
{
    window.location.href = "mailto:[email protected]";
}
<body onload="javascript: redirect();">

Or just directly

<body onload="javascript: window.location.href='mailto:[email protected]';">

Rather than abusing plot or annotate, which will be inefficient for many lines, you can use matplotlib.collections.LineCollection:

import numpy as np
import matplotlib.pyplot as plt
from matplotlib.collections import LineCollection

np.random.seed(5)
x = np.arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
plt.plot(x, y, "o")

# Takes list of lines, where each line is a sequence of coordinates
l1 = [(70, 100), (70, 250)]
l2 = [(70, 90), (90, 200)]
lc = LineCollection([l1, l2], color=["k","blue"], lw=2)

plt.gca().add_collection(lc)

plt.show()

It takes a list of lines [l1, l2, ...], where each line is a sequence of N coordinates (N can be more than two).

The standard formatting keywords are available, accepting either a single value, in which case the value applies to every line, or a sequence of M values, in which case the value for the ith line is values[i % M].

You can use the following rule to redirect from https to http :

 RewriteEngine On


RewriteCond %{HTTPS} ^on$
RewriteRule ^(.*)$ http://example.com/$1 [NC,L,R]

Explanation :

RewriteCond %{HTTPS} ^on$

Checks if the HTTPS is on (Request is made using https)

Then

RewriteRule ^(.*)$ http://example.com/$1 [NC,L,R]

Redirect any request (https://example.com/foo) to http://example.com/foo .

• $1 is part of the regex in RewriteRule pattern, it contains whatever value was captured in (.+) , in this case ,it captures the full request_uri everything after the domain name.

• [NC,L,R] are the flags, NC makes the uri case senstive, you can use both uppercase or lowercase letters in the request.

L flag tells the server to stop proccessing other rules if the currunt rule has matched, it is important to use the L flag to avoid rule confliction when you have more then on rules in a block.

R flag is used to make an external redirection.

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

It seems there is an issue with glibc that affects the memory allocation in Pandas: https://github.com/pandas-dev/pandas/issues/2659

The monkey patch detailed on this issue has resolved the problem for me:

# monkeypatches.py

# Solving memory leak problem in pandas
# https://github.com/pandas-dev/pandas/issues/2659#issuecomment-12021083
import pandas as pd
from ctypes import cdll, CDLL
try:
    cdll.LoadLibrary("libc.so.6")
    libc = CDLL("libc.so.6")
    libc.malloc_trim(0)
except (OSError, AttributeError):
    libc = None

__old_del = getattr(pd.DataFrame, '__del__', None)

def __new_del(self):
    if __old_del:
        __old_del(self)
    libc.malloc_trim(0)

if libc:
    print('Applying monkeypatch for pd.DataFrame.__del__', file=sys.stderr)
    pd.DataFrame.__del__ = __new_del
else:
    print('Skipping monkeypatch for pd.DataFrame.__del__: libc or malloc_trim() not found', file=sys.stderr)

If you want also the position of the new array key to be the same as the old one you can do this:

function change_array_key( $array, $old_key, $new_key) {
    if(!is_array($array)){ print 'You must enter a array as a haystack!'; exit; }
    if(!array_key_exists($old_key, $array)){
        return $array;
    }

    $key_pos = array_search($old_key, array_keys($array));
    $arr_before = array_slice($array, 0, $key_pos);
    $arr_after = array_slice($array, $key_pos + 1);
    $arr_renamed = array($new_key => $array[$old_key]);

    return $arr_before + $arr_renamed + $arr_after;
}

The error code 0x800A03EC (or -2146827284) means NAME_NOT_FOUND; in other words, you've asked for something, and Excel can't find it.

This is a generic code, which can apply to lots of things it can't find e.g. using properties which aren't valid at that time like PivotItem.SourceNameStandard throws this when a PivotItem doesn't have a filter applied. Worksheets["BLAHBLAH"] throws this, when the sheet doesn't exist etc. In general, you are asking for something with a specific name and it doesn't exist. As for why, that will taking some digging on your part.

Check your sheet definitely does have the Range you are asking for, or that the .CellName is definitely giving back the name of the range you are asking for.

If you have a standard code signing certificate, some time will be needed for your application to build trust. Microsoft affirms that an Extended Validation (EV) Code Signing Certificate allows us to skip this period of trust-building. According to Microsoft, extended validation certificates allow the developer to immediately establish a reputation with SmartScreen. Otherwise, the users will see a warning like "Windows Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.", with the two buttons: "Run anyway" and "Don't run".

Another Microsoft resource states the following (quote): "Although not required, programs signed by an EV code signing certificate can immediately establish a reputation with SmartScreen reputation services even if no prior reputation exists for that file or publisher. EV code signing certificates also have a unique identifier which makes it easier to maintain reputation across certificate renewals."

My experience is as follows. Since 2005, we have been using regular (non-EV) code signing certificates to sign .MSI, .EXE and .DLL files with time stamps, and there has never been a problem with SmartScreen until 2018, when there was just one case when it took 3 days for a beta version of our application to build trust since we have released it to beta testers, and it was in the middle of certificate validity period. I don't know what SmartScreen might not like in that specific version of our application, but there have been no SmartScreen complaints since then. Therefore, if your certificate is a non-EV, it is a signed application (such as an .MSI file) that will build trust over time, not a certificate. For example, a certificate can be issued a few months ago and used to sign many files, but for each signed file you publish, it may take a few days for SmartScreen to stop complaining about the file after publishing, as was in our case in 2018.

As a conclusion, to avoid the warning completely, i.e. prevent it from happening even suddenly, you need an Extended Validation (EV) code signing certificate.

Try rewriting your success handler to:

success : handleData

The success property of the ajax method only requires a reference to a function.

In your handleData function you can take up to 3 parameters:

object data
string textStatus
jqXHR jqXHR

Adding answer to show example of stripping multiple characters including \r using tr and using sed. And illustrating using hexdump.

In my case I had found that a command ending with awk print of the last item |awk '{print $2}' in the line included a carriage-return \r as well as quotes.

I used sed 's/["\n\r]//g' to strip both the carriage-return and quotes.

I could also have used tr -d '"\r\n'.

Interesting to note sed -z is needed if one wishes to remove \n line-feed chars.

$ COMMAND=$'\n"REBOOT"\r   \n'

$ echo "$COMMAND" |hexdump -C
00000000  0a 22 52 45 42 4f 4f 54  22 0d 20 20 20 0a 0a     |."REBOOT".   ..|

$ echo "$COMMAND" |tr -d '"\r\n' |hexdump -C
00000000  52 45 42 4f 4f 54 20 20  20                       |REBOOT   |

$ echo "$COMMAND" |sed 's/["\n\r]//g' |hexdump -C
00000000  0a 52 45 42 4f 4f 54 20  20 20 0a 0a              |.REBOOT   ..|

$ echo "$COMMAND" |sed -z 's/["\n\r]//g' |hexdump -C
00000000  52 45 42 4f 4f 54 20 20  20                       |REBOOT   |

And this is relevant: What are carriage return, linefeed, and form feed?

• CR == \r == 0x0d
• LF == \n == 0x0a

You can use strptime(3) to parse the time, and then mktime(3) to convert it to a time_t:

const char *time_details = "16:35:12";
struct tm tm;
strptime(time_details, "%H:%M:%S", &tm);
time_t t = mktime(&tm);  // t is now your desired time_t

This worked for me, when i tried to use my application without debugging it.

The problem you're having is that the event-handlers are being bound before the elements are present in the DOM, if you wrap the jQuery inside of a $(document).ready() then it should work perfectly well:

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").show("slow");
        });

    });

An alternative is to place the <script></script> at the foot of the page, so it's encountered after the DOM has been loaded and ready.

To make the div hide again, once the #music element is clicked, simply use toggle():

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").toggle();
        });
    });

JS Fiddle demo.

And for fading:

$(document).ready(
    function(){
        $("#music").click(function () {
            $("#musicinfo").fadeToggle();
        });
    });

JS Fiddle demo.

Another way to wait for maximum of certain amount say 10 seconds of time for the element to be displayed as below:

(new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
            public Boolean apply(WebDriver d) {
                return d.findElement(By.id("<name>")).isDisplayed();

            }
        });

Very late to the party, but A simple solution is using VBA to create a custom function.

Add the function to VBA in the WorkBook, Worksheet, or a VBA Module

Function LastSegment(S, C)
    LastSegment = Right(S, Len(S) - InStrRev(S, C))
End Function

Then the cell formula

=lastsegment(B1,"/")

in a cell and the string to be searched in cell B1 will populate the cell with the text trailing the last "/" from cell B1. No length limit, no obscure formulas. Only downside I can think is the need for a macro-enabled workbook.

Any user VBA Function can be called this way to return a value to a cell formula, including as a parameter to a builtin Excel function.

If you are going to use the function heavily you'll want to check for the case when the character is not in the string, then string is blank, etc.

This can occur on android too not just computers. Was browsing using Kiwi when the site I was on began to endlessly redirect so I cut net access to close it out and noticed my phone had DL'd something f.txt in my downloaded files.

Deleted it and didn't open.

Just change the SqlCommand.CommandText instead of creating a new SqlCommand every time. There is no need to close and reopen the connection.

// Create the first command and execute
var command = new SqlCommand("<SQL Command>", myConnection);
var reader = command.ExecuteReader();

// Change the SQL Command and execute
command.CommandText = "<New SQL Command>";
command.ExecuteNonQuery();

Change localhost:8080 to localhost:3306.
