Here's my current solution to run any code remotely on a given machine or list of machines asynchronously with logging, too!

@echo off
:: by Ralph Buchfelder, thanks to Mark Russinovich and Rob van der Woude for their work!
:: requires PsExec.exe to be in the same directory (download from http://technet.microsoft.com/de-de/sysinternals/bb897553.aspx)
:: troubleshoot remote commands with PsExec arguments -i or -s if neccessary (see http://forum.sysinternals.com/pstools_forum8.html)
:: will run *in parallel* on a list of remote pcs (if given); to run serially please remove 'START "" CMD.EXE /C' from the psexec call

I use the following syntax :

$Domain=[System.Net.Dns]::GetHostByName($VM).Hostname.split('.')
$Domain=$Domain[1]+'.'+$Domain[2]

it does not matter if the $VM is up or down...

I've encountered this problem when the build is abruptly closed before it is loaded. No process would show up in the Task Manager, but if you navigate to the executable generated in the project folder and try to delete it, Windows claims that the application is in use. (If not, just delete the file and rebuild, which generates a new executable) In Windows(Visual Studio 2019), the file is located in this directory by default:

%USERPROFILE%\source\repos\ProjectFolderName\Debug

To end the allegedly running process, open the command prompt and type in the following command:

taskkill /F /IM ApplicationName.exe

This forces any running instance to be terminated. Rebuild and execute!

I just had this issue building react-native app when I try to install Pod. I had to export 2 variables:

export CC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc
CPP='/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc -E'

When you run a .ps1 PowerShell script you might get the message saying “.ps1 is not digitally signed. The script will not execute on the system.” To fix it you have to run the command below to run Set-ExecutionPolicy and change the Execution Policy setting.

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass

Can you try the following?

psexec \\server cmd /c "echo . | powershell script.ps1"

As other have said, TRUNCATE TABLE is far quicker, but it does have some restrictions (taken from here):

You cannot use TRUNCATE TABLE on tables that:

- Are referenced by a FOREIGN KEY constraint. (You can truncate a table that has a foreign key that references itself.)
- Participate in an indexed view.
- Are published by using transactional replication or merge replication.

For tables with one or more of these characteristics, use the DELETE statement instead.

The biggest drawback is that if the table you are trying to empty has foreign keys pointing to it, then the truncate call will fail.

One of the good things about handle.exe is that you can run it as a subprocess and parse the output.

We do this in our deployment script - works like a charm.

The following script will give you free bytes on the drive:

@setlocal enableextensions enabledelayedexpansion
@echo off
for /f "tokens=3" %%a in ('dir c:\') do (
    set bytesfree=%%a
)
set bytesfree=%bytesfree:,=%
echo %bytesfree%
endlocal && set bytesfree=%bytesfree%

Note that this depends on the output of your dir command, which needs the last line containing the free space of the format 24 Dir(s) 34,071,691,264 bytes free. Specifically:

• it must be the last line (or you can modify the for loop to detect the line explicitly rather than relying on setting bytesfree for every line).
• the free space must be the third "word" (or you can change the tokens= bit to get a different word).
• thousands separators are the , character (or you can change the substitution from comma to something else).

It doesn't pollute your environment namespace, setting only the bytesfree variable on exit. If your dir output is different (eg, different locale or language settings), you will need to adjust the script.

I followed around five different answers as well as all the blog posts in the previous answers and still had problems. I was trying to add a listener to some existing code that was tracing using the TraceSource.TraceEvent(TraceEventType, Int32, String) method where the TraceSource object was initialised with a string making it a 'named source'.

For me the issue was not creating a valid combination of source and switch elements to target this source. Here is an example that will log to a file called tracelog.txt. For the following code:

TraceSource source = new TraceSource("sourceName");
source.TraceEvent(TraceEventType.Verbose, 1, "Trace message");

I successfully managed to log with the following diagnostics configuration:

<system.diagnostics>
    <sources>
        <source name="sourceName" switchName="switchName">
            <listeners>
                <add
                    name="textWriterTraceListener"
                    type="System.Diagnostics.TextWriterTraceListener"
                    initializeData="tracelog.txt" />
            </listeners>
        </source>
    </sources>

    <switches>
        <add name="switchName" value="Verbose" />
    </switches>
</system.diagnostics>

Don't forget to create your migrations after writing the models

ok, here is what i understood from your question. You are writing a csv file from python but when you are opening that file into some other application like excel or open office they are showing the complete row in one cell rather than each word in individual cell. I am right??

if i am then please try this,

import csv

with open(r"C:\\test.csv", "wb") as csv_file:
    writer = csv.writer(csv_file, delimiter =",",quoting=csv.QUOTE_MINIMAL)
    writer.writerow(["a","b"])

you have to set the delimiter = ","

Thanks @Vincent Robert, I ended up using your basic example, though it's actually newBegin + oldEnd - oldBegin. Here's the simplified end solution:

    // don't update end date if there's already an end date but not an old start date
    if (!oldEnd || oldBegin) {
        var selectedDateSpan = 1800000; // 30 minutes
        if (oldEnd) {
            selectedDateSpan = oldEnd - oldBegin;
        }

       newEnd = new Date(newBegin.getTime() + selectedDateSpan));
    }

I don't program Scala, but I use another language with implicit returns (Ruby). You have code after your if (elem.isEmpty) block -- the last line of code is what's returned, which is why you're not getting what you're expecting.

EDIT: Here's a simpler way to write your function too. Just use the boolean value of isEmpty and count to return true or false automatically:

def balanceMain(elem: List[Char]): Boolean =
{
    elem.isEmpty && count == 0
}

To get the Color from Hex.

using System.Windows.Media;

Color color = (Color)ColorConverter.ConvertFromString("#FFDFD991");

and then set the foreground

textBlock.Foreground = new System.Windows.Media.SolidColorBrush(color); 

Just use var = var1 var2 and it will automatically concatenate the vars var1 and var2:

awk '{new_var=$1$2; print new_var}' file

You can put an space in between with:

awk '{new_var=$1" "$2; print new_var}' file

Which in fact is the same as using FS, because it defaults to the space:

awk '{new_var=$1 FS $2; print new_var}' file

Test

$ cat file
hello how are you
i am fine
$ awk '{new_var=$1$2; print new_var}' file
hellohow
iam
$ awk '{new_var=$1 FS $2; print new_var}' file
hello how
i am

It's easy to make a message, here's how:

First open notpad and type:

msg "Message",0,"Title"

and save it as Message.vbs.

Now in your batch file type:

Message.vbs %*

There are several Identity providers with SSO support out of the box, also third-party** products.

** The only problem with third party products is that they charge per user/month, and it can be quite expensive.

Some of the tools available and with APIs for .NET are:

• IdentityExpress (with Admin UI) by IdentityServer
• Centrify Identity Service
• Okta Identity (SAML 2.0)
• OneLogin

If you decide to go with your own implementation, you could use the frameworks below categorized by programming language.

• C#

  • IdentityServer3 (OAuth/OpenID protocols, OWIN/Katana)
  • IdentityServer4 (OAuth/OpenID protocols, ASP.NET Core)
  • OAuth 2.0 by Okta

• Javascript

  • passport-openidconnect (node.js)
  • oidc-provider (node.js)
  • openid-client (node.js)

• Python

  • pyoidc
  • Django OIDC Provider

I would go with IdentityServer4 and ASP.NET Core application, it's easy configurable and you can also add your own authentication provider. It uses OAuth/OpenID protocols which are newer than SAML 2.0 and WS-Federation.

Yes, querySelectorAll does take a group of selectors:

form, p, legend

Quicktime movs exported as animation work but in safari only. I wish there was a complete solution (or format) that covered all major browsers.

It may be worth mentioning that running tomcat as a non root user (which you should be doing) will prevent you from using a port below 1024 on *nix. If you want to use TC as a standalone server -- as its performance no longer requires it to be fronted by Apache or the like -- you'll want to bind to port 80 along with whatever IP address you're specifying.

You can do this by using IPTABLES to redirect port 80 to 8080.

Thou the above answer is widely accepted and well documented, I found some of the reason to post my answer here :-

    doNothing().when(InternalUtils.class); //This is the preferred way
                                           //to mock static void methods.
    InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

Here, I dont understand why we are calling InternalUtils.sendEmail ourself. I will explain in my code why we don't need to do that.

mockStatic(Internalutils.class);

So, we have mocked the class which is fine. Now, lets have a look how we need to verify the sendEmail(/..../) method.

@PrepareForTest({InternalService.InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest {

    @Mock
    private InternalService.Order order;

    private InternalService internalService;

    @Before
    public void setup() {
        MockitoAnnotations.initMocks(this);
        internalService = new InternalService();
    }

    @Test
    public void processOrder() throws Exception {

        Mockito.when(order.isSuccessful()).thenReturn(true);
        PowerMockito.mockStatic(InternalService.InternalUtils.class);

        internalService.processOrder(order);

        PowerMockito.verifyStatic(times(1));
        InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());
    }

}

These two lines is where the magic is, First line tells the PowerMockito framework that it needs to verify the class it statically mocked. But which method it need to verify ?? Second line tells which method it needs to verify.

PowerMockito.verifyStatic(times(1));
InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());

This is code of my class, sendEmail api twice.

public class InternalService {

    public void processOrder(Order order) {
        if (order.isSuccessful()) {
            InternalUtils.sendEmail("", new String[1], "", "");
            InternalUtils.sendEmail("", new String[1], "", "");
        }
    }

    public static class InternalUtils{

        public static void sendEmail(String from, String[]  to, String msg, String body){

        }

    }

    public class Order{

        public boolean isSuccessful(){
            return true;
        }

    }

}

As it is calling twice you just need to change the verify(times(2))... that's all.

if you do not want to be bothered by the date format, you could compare the column with the general date format, for example

select * From table where cast (RegistrationDate as date) between '20161201' and '20161220'

make sure the date is in DATE format, otherwise cast (col as DATE)

If we take a look at the source for bytes.__repr__, it looks as if the b'' is baked into the method.

The most obvious workaround is to manually slice off the b'' from the resulting repr():

>>> x = b'\x01\x02\x03\x04'

>>> print(repr(x))
b'\x01\x02\x03\x04'

>>> print(repr(x)[2:-1])
\x01\x02\x03\x04

Check in Administration Tools\Services (or type services.msc in the console if you a service named SQL Server (SQLEXPRESS). If you do then it is installed.

From Visual Studio open Server Explorer (menu View\Server Explorer or CTRL + W, L). Right click Data Connections and choose Create New SQL Server Database. After that create tables and stuff...

If you want the Management Studio to manage the server you must download and install it from:

permissions:

 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Try this:

        {
            SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=Stocks;Integrated Security=True;Pooling=False");
            SqlDataAdapter sda = new SqlDataAdapter("Select * From [Stocks].[dbo].[product]", con);
            DataTable dt = new DataTable();
            sda.Fill(dt);
            DataGridView1.Rows.Clear();

        foreach (DataRow item in dt.Rows)
        {
            int n = DataGridView1.Rows.Add();
            DataGridView1.Rows[n].Cells[0].Value = item["ProductCode"].ToString();
            DataGridView1.Rows[n].Cells[1].Value = item["Productname"].ToString();
            DataGridView1.Rows[n].Cells[2].Value = item["qty"].ToString();                
            if ((bool)item["productstatus"])
            {
                DataGridView1.Rows[n].Cells[3].Value = "Active";
            }
            else
            {
                DataGridView1.Rows[n].Cells[3].Value = "Deactive";
            }

I also had the same problem. It's easy to divide integer numbers but decimal numbers are not that easy. if you have 2 numbers like 3.14 and 2.35 and divide the numbers then, the code will be Division=echo 3.14 / 2.35 | bc echo "$Division" the quotes are different. Don't be confused, it's situated just under the esc button on your keyboard. THE ONLY DIFFERENCE IS THE | bc and also here echo works as an operator for the arithmetic calculations in stead of printing. So, I had added echo "$Division" for printing the value. Let me know if it works for you. Thank you.

Another way to get the same result:

date <- strptime(v,format="%Y%m%d")

Loop like

foreach (GridViewRow row in grid.Rows)
{
   if (((CheckBox)row.FindControl("chkboxid")).Checked)
   {
    //read the label

I figured out that this behaves like a mousedown event:

button:active:hover {}

It appears to be working fine for mm/dd/yyyy format dates, example:

http://jsfiddle.net/niklasvh/xfrLm/

The only problem I had with your code was the fact that:

var ExpiryDate = document.getElementById(' ExpiryDate').value;

Had a space inside the brackets, before the element ID. Changed it to:

var ExpiryDate = document.getElementById('ExpiryDate').value;

Without any further details regarding the type of data that isn't working, there isn't much else to give input on.

In your case:

MemoryStream ms = new MemoryStream(buffer);

Check out the jQuery dimensions plugin

sample = ("Python 3.2 is very easy") #sample string  
letters = 0  # initiating the count of letters to 0
numeric = 0  # initiating the count of numbers to 0

        for i in sample:  
            if i.isdigit():      
                numeric +=1      
            elif i.isalpha():    
                letters +=1    
            else:    
               pass

A Natural Join is where 2 tables are joined on the basis of all common columns.

common column : is a column which has same name in both tables + has compatible datatypes in both the tables. You can use only = operator

A Inner Join is where 2 tables are joined on the basis of common columns mentioned in the ON clause.

common column : is a column which has compatible datatypes in both the tables but need not have the same name. You can use only any comparision operator like =, <=, >=, <, >, <>

set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%

• The single quotes do not indicate a string, they make it starts: 'C:\ instead of C:\ so

• %name% is the usual syntax for expanding a variable, the !name! syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION first, or by running the command prompt with CMD /V:ON.

• Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4 to keep the current PATH content, and add something to the end.

The easiest way to accomplish this is to package the desired font(s) with your application. To do this, simply create an assets/ folder in the project root, and put your fonts (in TrueType, or TTF, form) in the assets. You might, for example, create assets/fonts/ and put your TTF files in there.

Then, you need to tell your widgets to use that font. Unfortunately, you can no longer use layout XML for this, since the XML does not know about any fonts you may have tucked away as an application asset. Instead, you need to make the change in Java code, by calling Typeface.createFromAsset(getAssets(), “fonts/HandmadeTypewriter.ttf”), then taking the created Typeface object and passing it to your TextView via setTypeface().

For more reference here is the tutorial where I got this:

I could happen that if your array contains the string "hello", and if you are searching for "he", grep returns true, although, "he" may not be an array element.

Perhaps,

if (grep(/^$match$/, @array)) more apt.

OK, I found it finally.

Key Event This document lists volume up as 24. The key code I was looking for is Alt-Menu and apparently it executes regardless of having the key intercepted.

echo "<a href='index.php'>Index Page</a>";

if you wanna use html tag like anchor tag you have to put in echo

You can do it this way:

=IF(E9>21,"Text 1",IF(AND(E9>=5,E9<=21),"Test 2","Text 3"))

Note I assume you meant >= and <= here since your description skipped the values 5 and 21, but you can adjust these inequalities as needed.

Or you can do it this way:

=IF(E9>21,"Text 1",IF(E9<5,"Text 3","Text 2"))

let str = "abc"
let substr = str.substringToIndex(str.endIndex.predecessor())  // "ab"

The usual way to set the line color in matplotlib is to specify it in the plot command. This can either be done by a string after the data, e.g. "r-" for a red line, or by explicitely stating the color argument.

import matplotlib.pyplot as plt

plt.plot([1,2,3], [2,3,1], "r-") # red line
plt.plot([1,2,3], [5,5,3], color="blue") # blue line

plt.show()

See also the plot command's documentation.

In case you already have a line with a certain color, you can change that with the lines2D.set_color() method.

line, = plt.plot([1,2,3], [4,5,3], color="blue")
line.set_color("black")

import matplotlib.pyplot as plt
import pandas as pd

df = pd.DataFrame({ "x" : [1,2,3,5], "y" : [3,5,2,6]})
df.plot("x", "y", color="r") #plot red line

plt.show()

If you want to change this color later on, you can do so by

plt.gca().get_lines()[0].set_color("black")

This will get you the first (possibly the only) line of the current active axes.
In case you have more axes in the plot, you could loop through them

for ax in plt.gcf().axes:
    ax.get_lines()[0].set_color("black")

and if you have more lines you can loop over them as well.

Its simple If you are passing String X from A to B.
A--> B

In Activity A
1) Create Intent
2) Put data in intent using putExtra method of intent
3) Start activity

Intent i = new Intent(A.this, B.class);
i.putExtra("MY_kEY",X);

In Activity B
inside onCreate method
1) Get intent object
2) Get stored value using key(MY_KEY)

Intent intent = getIntent();
String result = intent.getStringExtra("MY_KEY");

This is the standard way to send data from A to B. you can send any data type, it could be int, boolean, ArrayList, String[]. Based on the datatype you stored in Activity as key, value pair retrieving method might differ like if you are passing int value then you will call

intent.getIntExtra("KEY");

You can even send Class objects too but for that, you have to make your class object implement the Serializable or Parceable interface.

TransactionTooLargeException

How much data you can send across size. If data exceeds a certain amount in size then you might get TransactionTooLargeException. Suppose you are trying to send bitmap across the activity and if the size exceeds certain data size then you might see this exception.

no need to do so many things. for set value using multiple select2 var selectedvalue="1,2,3"; //if first 3 products are selected. $('#ddlProduct').val(selectedvalue);

If you want to match the two words in either order, use:

gci C:\Logs| select-string -pattern '(VendorEnquiry.*Failed)|(Failed.*VendorEnquiry)'

If Failed always comes after VendorEnquiry on the line, just use:

gci C:\Logs| select-string -pattern '(VendorEnquiry.*Failed)'

Here is a quick-and-dirty way to replace all the broken images, and there is no need to change the HTML code ;)

codepen example

    $("img").each(function(){
        var img = $(this);
        var image = new Image();
        image.src = $(img).attr("src");
        var no_image = "https://dummyimage.com/100x100/7080b5/000000&text=No+image";
        if (image.naturalWidth == 0 || image.readyState == 'uninitialized'){
            $(img).unbind("error").attr("src", no_image).css({
                height: $(img).css("height"),
                width: $(img).css("width"),
            });
        }
  });

This is the answer if someone want to know

if (Date.now() >= exp * 1000) {
  return false;
}

This answer might not be 100% relevant to the question. But it does address the problem. I found this simple way of achieving this requirement. Code goes below:

<a href="@Url.Action("Display", "Customer")?custId={{cust.Id}}"></a>

In the above example {{cust.Id}} is an AngularJS variable. However one can replace it with a JavaScript variable.

I haven't tried passing multiple variables using this method but I'm hopeful that also can be appended to the Url if required.

For me, I had things unnecessarily split into separate folders. I'm running plotly dash and I had my Procfile, and Pipfile (and lock) together, but separate from the other features of my app (run.py and app.py, the actual content of the pages being used was in a subfolder). So joining much of that together repaired my H10 error

For lazy people, like me, a snippet based on Nikhil's solution

<input id=username type="text" placeholder="github username or repo link">_x000D_
<button onclick="fetch(`https://api.github.com/users/${username.value.replace(/^.*com[/]([^/]*).*$/,'$1')}/events/public`).then(e=> e.json()).then(e => [...new Set([].concat.apply([],e.filter(x => x.type==='PushEvent').map(x => x.payload.commits.map(c => c.author.email)))).values()]).then(x => results.innerText = x)">GO</button>_x000D_
<div id=results></div>

Replace

onclick="changeLink();"

by

onclick="changeLink(); return false;"

to cancel its default action

All you have to do is just change the hard coded value in the code provided below

DECLARE @firstDate datetime
    DECLARE @secondDate datetime
    DECLARE @totalDays  INT
    SELECT @firstDate = getDate() - 30
    SELECT @secondDate = getDate()

    DECLARE @index INT
    SELECT @index = 0
    SELECT @totalDays = datediff(day, @firstDate, @secondDate)

    CREATE TABLE #temp
    (
         ID INT NOT NULL IDENTITY(1,1)
        ,CommonDate DATETIME NULL
    )

    WHILE @index < @totalDays
        BEGIN

            INSERT INTO #temp (CommonDate) VALUES  (DATEADD(Day, @index, @firstDate))   
            SELECT @index = @index + 1
        END

    SELECT CONVERT(VARCHAR(10), CommonDate, 102) as [Date Between] FROM #temp

    DROP TABLE #temp

the problem here is that by using the apostrophes you are setting the value being passed to be a string, when in fact, as @Shijo stated from the documentation, the function is expecting a label or list, but not a string! If the list contains each of the name of the columns beings passed for both the left and right dataframe, then each column-name must individually be within apostrophes. With what has been stated, we can understand why this is inccorect:

new_df = pd.merge(A_df, B_df,  how='left', left_on='[A_c1,c2]', right_on = '[B_c1,c2]')

And this is the correct way of using the function:

new_df = pd.merge(A_df, B_df,  how='left', left_on=['A_c1','c2'], right_on = ['B_c1','c2'])

.joins will just joins the tables and brings selected fields in return. if you call associations on joins query result, it will fire database queries again

:includes will eager load the included associations and add them in memory. :includes loads all the included tables attributes. If you call associations on include query result, it will not fire any queries

I think

event.preventDefault()

is the w3c specified way of canceling events.

You can read this in the W3C spec on Event cancelation.

Also you can't use return false in every situation. When giving a javascript function in the href attribute and if you return false then the user will be redirected to a page with false string written.

year(@date)
year(getdate())
year('20120101')

update table
set column = year(date_column)
whre ....

or if you need it in another table

 update t
   set column = year(t1.date_column)
     from table_source t1
     join table_target t on (join condition)
    where ....

Passive event listeners are an emerging web standard, new feature shipped in Chrome 51 that provide a major potential boost to scroll performance. Chrome Release Notes.

It enables developers to opt-in to better scroll performance by eliminating the need for scrolling to block on touch and wheel event listeners.

Problem: All modern browsers have a threaded scrolling feature to permit scrolling to run smoothly even when expensive JavaScript is running, but this optimization is partially defeated by the need to wait for the results of any touchstart and touchmove handlers, which may prevent the scroll entirely by calling preventDefault() on the event.

Solution: {passive: true}

By marking a touch or wheel listener as passive, the developer is promising the handler won't call preventDefault to disable scrolling. This frees the browser up to respond to scrolling immediately without waiting for JavaScript, thus ensuring a reliably smooth scrolling experience for the user.

document.addEventListener("touchstart", function(e) {
    console.log(e.defaultPrevented);  // will be false
    e.preventDefault();   // does nothing since the listener is passive
    console.log(e.defaultPrevented);  // still false
}, Modernizr.passiveeventlisteners ? {passive: true} : false);

Depends on your requirment, but the most effective way to create is:

 Product obj = new Product
            {
                ID = 21,
                Price = 200,
                Category = "XY",
                Name = "SKR",
            };

For reference, you can also utilize initWithDictionary to init the NSMutableDictionary with a literal one:

NSMutableDictionary buttons = [[NSMutableDictionary alloc] initWithDictionary: @{
    @"touch": @0,
    @"app": @0,
    @"back": @0,
    @"volup": @0,
    @"voldown": @0
}];

Changing the value to dynamic will put an entry in your app.config.

Here is the CodePlex article that has more information.

Heres another approach that I used when doing something similar for a large telescope:

1) Search for the highest pixel. Once you have that, search around that for the best fit for 2x2 (maybe maximizing the 2x2 sum), or do a 2d gaussian fit inside the sub region of say 4x4 centered on the highest pixel.

Then set those 2x2 pixels you have found to zero (or maybe 3x3) around the peak center

go back to 1) and repeat till the highest peak falls below a noise threshold, or you have all the toes you need

For .NET Core, add System.Configuration.ConfigurationManager from NuGet manager.
And read appSetting from App.config

<appSettings>
  <add key="appSetting1" value="1000" />
</appSettings>

Add System.Configuration.ConfigurationManager from NuGet Manager

ConfigurationManager.AppSettings.Get("appSetting1")

This problem has bothered me for 15 years, and all the solutions supplied weren't satisfactory for me. How do you create a dynamic multidimensional array contiguously in memory? Today I finally found the answer. Using the following code, you can do just that:

#include <iostream>

int main(int argc, char** argv)
{
    if (argc != 3)
    {
        std::cerr << "You have to specify the two array dimensions" << std::endl;
        return -1;
    }

    int sizeX, sizeY;

    sizeX = std::stoi(argv[1]);
    sizeY = std::stoi(argv[2]);

    if (sizeX <= 0)
    {
        std::cerr << "Invalid dimension x" << std::endl;
        return -1;
    }
    if (sizeY <= 0)
    {
        std::cerr << "Invalid dimension y" << std::endl;
        return -1;
    }

    /******** Create a two dimensional dynamic array in continuous memory ******
     *
     * - Define the pointer holding the array
     * - Allocate memory for the array (linear)
     * - Allocate memory for the pointers inside the array
     * - Assign the pointers inside the array the corresponding addresses
     *   in the linear array
     **************************************************************************/

    // The resulting array
    unsigned int** array2d;

    // Linear memory allocation
    unsigned int* temp = new unsigned int[sizeX * sizeY];

    // These are the important steps:
    // Allocate the pointers inside the array,
    // which will be used to index the linear memory
    array2d = new unsigned int*[sizeY];

    // Let the pointers inside the array point to the correct memory addresses
    for (int i = 0; i < sizeY; ++i)
    {
        array2d[i] = (temp + i * sizeX);
    }



    // Fill the array with ascending numbers
    for (int y = 0; y < sizeY; ++y)
    {
        for (int x = 0; x < sizeX; ++x)
        {
            array2d[y][x] = x + y * sizeX;
        }
    }



    // Code for testing
    // Print the addresses
    for (int y = 0; y < sizeY; ++y)
    {
        for (int x = 0; x < sizeX; ++x)
        {
            std::cout << std::hex << &(array2d[y][x]) << ' ';
        }
    }
    std::cout << "\n\n";

    // Print the array
    for (int y = 0; y < sizeY; ++y)
    {
        std::cout << std::hex << &(array2d[y][0]) << std::dec;
        std::cout << ": ";
        for (int x = 0; x < sizeX; ++x)
        {
            std::cout << array2d[y][x] << ' ';
        }
        std::cout << std::endl;
    }



    // Free memory
    delete[] array2d[0];
    delete[] array2d;
    array2d = nullptr;

    return 0;

As you can see, the multidimensional array lies contiguously in memory, and no two memory addresses are overlapping. Even the routine for freeing the array is simpler than the standard way of dynamically allocating memory for every single column (or row, depending on how you view the array). Since the array basically consists of two linear arrays, only these two have to be (and can be) freed.

This method can be extended for more than two dimensions with the same concept. I won't do it here, but when you get the idea behind it, it is a simple task.

I hope this code will help you as much as it helped me.

Worked for me by running the command prompt as an administrator

You could write an extension method called Reset(), which

• calls Stop()-Start() for Timers.Timer and Forms.Timer
• calls Change for Threading.Timer

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

Other users commenting that the Content-Type is plain/text when encoding. You have to set the Content-Type first w.Header().Set, then the HTTP response code w.WriteHeader.

If you call w.WriteHeader first then call w.Header().Set after you will get plain/text.

An example handler might look like this;

func SomeHandler(w http.ResponseWriter, r *http.Request) {
    data := SomeStruct{}
    w.Header().Set("Content-Type", "application/json")
    w.WriteHeader(http.StatusCreated)
    json.NewEncoder(w).Encode(data)
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace GuessTheDay
{
class Program
{
    static void Main(string[] args)
    { 
 Console.WriteLine("Enter the Day Number ");
 int day = int.Parse(Console.ReadLine());
 Console.WriteLine(" Enter The Month");
int month = int.Parse(Console.ReadLine());
Console.WriteLine("Enter Year ");
int year = int.Parse(Console.ReadLine());
DateTime mydate = new DateTime(year,month,day);
string formatteddate = string.Format("{0:dddd}", mydate);
Console.WriteLine("The day should be " + formatteddate);
}  
 } 
   }

I had this problem and I could solve it by doing php artisan config:cache. The problem was that I had already run that command previously and later included some new seeder classes. The cached configurations didn't recognize the new classes. So running that command again worked.

If you see yourself making frequent changes to include new seeder classes then consider running php artisan config:clear. This will enable you to make as many changes as you'd like and then after testing you can run config:cache again to make things run optimally again.

The only solution for such warnings is to include stdlib.h in the program.

1. Soap ui -> New SOAPUI project -> use wsdl to create a project (lets assume we have a testService in it)
2. you will have a folder called TestService and then inside it there will be tokenTestServiceSoapBinding (example) -> right click on it
3. Export definition -> give location where you need to place the definition.
4. Exported location will have xsd and wsdl files. Hope this helps!

You could use sp_executesql instead of exec. That allows you to specify an output parameter.

declare @out_var varchar(max);
execute sp_executesql 
    N'select @out_var = ''hello world''', 
    N'@out_var varchar(max) OUTPUT', 
    @out_var = @out_var output;
select @out_var;

This prints "hello world".

You could just try using return false (return false overrides default behaviour on every DOM element) like that :

myform.onsubmit = function ()
{ 
  // do what you want
  return false
}

and then submit your form using myform.submit()

or alternatively :

mybutton.onclick = function () 
{
   // do what you want
   return false
}

Also, if you use type="button" your form will not be submitted.

To create setup projects in Visual Studio 2012 with InstallShield Limited Edition, watch this video.

The InstallShield limited edition that cannot install services.

"ISLE is by far the worst installer option and the upgraded, read - paid for, version is cumbersome to use at best and impossible in most situations. InnoSetup, Nullsoft, Advanced, WiX, or just about any other installer is better. If you did a survey you would see that nobody is using ISLE. I don't know why you guys continue to associate with InstallShield. It damages your credibility. Any developer worth half his weight in salt knows ISLE is worthless and when you stand behind it we have to question Microsoft's judgment."

By Edward Miller (comments in Visual Studio Installer Projects Extension).

The WiX Toolset, which, while powerful is exceeding user-unfriendly and has a steep learning curve. There is even a downloadable template for installing Windows services (ref. VS2012: Installer for Windows services?).

For Visual Studio 2013, see blog post Creating installers with Visual Studio.

I missed this problem after update studio and gradle ,in the log file tips me some maven store has certificate problem.

I tried restart statudio as somebody suggestion but dose work; and somebody said we should set the jre environment ,but I doesn't know how to set it on Mac . So I tried restart Mac. and start studio I found this tips.

so the problem is floating on the surface: solution: first step: restart computer ,there are too many problem after android studio update . second step:use the old gradle tool OR download the *pom and jar ,put in correct folder.

date.ToString("HH:mm:ss"); // for 24hr format
date.ToString("hh:mm:ss"); // for 12hr format, it shows AM/PM

Refer this link for other Formatters in DateTime.

The simplest way is to setOnTouchListener and return true for ViewPager.

mPager.setOnTouchListener(new OnTouchListener()
    {           
        @Override
        public boolean onTouch(View v, MotionEvent event)
        {
            return true;
        }
    });

sklearn.cross_validation is now changed to sklearn.model_selection

Just use

from sklearn.model_selection import train_test_split

I think that will work.

If the process is a child process and $BASHPID is not set, it is possible to query the ppid of a created child process of the running process. It might be a bit ugly, but it works. Example:

sleep 1 &
mypid=$(ps -o ppid= -p "$!")

Finally, I've defeated my CiSCO EAP-FAST corporate wifi network, and all our Android devices are now able to connect to it.

The walk-around I've performed in order to gain access to this kind of networks from an Android device are easiest than you can imagine.

There's a Wifi Config Editor in the Google Play Store you can use to "activate" the secondary CISCO Protocols when you are setting up a EAP wifi connection.

Its name is Wifi Config Advanced Editor.

• First, you have to setup your wireless network manually as close as you can to your "official" corporate wifi parameters.

• Save it.

• Go to the WCE and edit the parameters of the network you have created in the previous step.

• There are 3 or 4 series of settings you should activate in order to force the Android device to use them as a way to connect (the main site I think you want to visit is Enterprise Configuration, but don't forget to check all the parameters to change them if needed.
  As a suggestion, even if you have a WPA2 EAP-FAST Cipher, try LEAP in your setup. It worked for me as a charm.

• When you finished to edit the config, go to the main Android wifi controller, and force to connect to this network.

• Do not Edit the network again with the Android wifi interface.

I have tested it on Samsung Galaxy 1 and 2, Note mobile devices, and on a Lenovo Thinkpad Tablet.

There are two ways to add references via VBA to your projects

1) Using GUID

2) Directly referencing the dll.

Let me cover both.

But first these are 3 things you need to take care of

a) Macros should be enabled

b) In Security settings, ensure that "Trust Access To Visual Basic Project" is checked

c) You have manually set a reference to `Microsoft Visual Basic for Applications Extensibility" object

Way 1 (Using GUID)

I usually avoid this way as I have to search for the GUID in the registry... which I hate LOL. More on GUID here.

Topic: Add a VBA Reference Library via code

Link: http://www.vbaexpress.com/kb/getarticle.php?kb_id=267

'Credits: Ken Puls
Sub AddReference()
     'Macro purpose:  To add a reference to the project using the GUID for the
     'reference library

    Dim strGUID As String, theRef As Variant, i As Long

     'Update the GUID you need below.
    strGUID = "{00020905-0000-0000-C000-000000000046}"

     'Set to continue in case of error
    On Error Resume Next

     'Remove any missing references
    For i = ThisWorkbook.VBProject.References.Count To 1 Step -1
        Set theRef = ThisWorkbook.VBProject.References.Item(i)
        If theRef.isbroken = True Then
            ThisWorkbook.VBProject.References.Remove theRef
        End If
    Next i

     'Clear any errors so that error trapping for GUID additions can be evaluated
    Err.Clear

     'Add the reference
    ThisWorkbook.VBProject.References.AddFromGuid _
    GUID:=strGUID, Major:=1, Minor:=0

     'If an error was encountered, inform the user
    Select Case Err.Number
    Case Is = 32813
         'Reference already in use.  No action necessary
    Case Is = vbNullString
         'Reference added without issue
    Case Else
         'An unknown error was encountered, so alert the user
        MsgBox "A problem was encountered trying to" & vbNewLine _
        & "add or remove a reference in this file" & vbNewLine & "Please check the " _
        & "references in your VBA project!", vbCritical + vbOKOnly, "Error!"
    End Select
    On Error GoTo 0
End Sub

Way 2 (Directly referencing the dll)

This code adds a reference to Microsoft VBScript Regular Expressions 5.5

Option Explicit

Sub AddReference()
    Dim VBAEditor As VBIDE.VBE
    Dim vbProj As VBIDE.VBProject
    Dim chkRef As VBIDE.Reference
    Dim BoolExists As Boolean

    Set VBAEditor = Application.VBE
    Set vbProj = ActiveWorkbook.VBProject

    '~~> Check if "Microsoft VBScript Regular Expressions 5.5" is already added
    For Each chkRef In vbProj.References
        If chkRef.Name = "VBScript_RegExp_55" Then
            BoolExists = True
            GoTo CleanUp
        End If
    Next

    vbProj.References.AddFromFile "C:\WINDOWS\system32\vbscript.dll\3"

CleanUp:
    If BoolExists = True Then
        MsgBox "Reference already exists"
    Else
        MsgBox "Reference Added Successfully"
    End If

    Set vbProj = Nothing
    Set VBAEditor = Nothing
End Sub

Note: I have not added Error Handling. It is recommended that in your actual code, do use it :)

EDIT Beaten by mischab1 :)

add:

.SubItems.Add("asdasdasd");

to the last line of your code so it will look like this in the end.

listView1.Items.Add("sdasdasdasd").SubItems.Add("asdasdasd");

Another possibly helpful note.

Redis can be bound to multiple IPs - that's very helpful when you don't want to open it to entire world (0.0.0.0) but only make it accessible in local networks.

1. sudo nano /etc/redis/redis.conf
2. add your local network IP to the end of bind setting:

bind 127.0.0.1 10.0.0.1

3. restart the service: sudo service redis-server restart

Now you can easily access redis from other computers in same network, e.g. redis-cli -h 10.0.0.1

This is something I wrote a few minutes ago just messing around. Hope it helps!

public class Main {

public static void main(String[] args) {

    ArrayList<Integer> powers = new ArrayList<Integer>();
    ArrayList<Integer> binaryStore = new ArrayList<Integer>();

    powers.add(128);
    powers.add(64);
    powers.add(32);
    powers.add(16);
    powers.add(8);
    powers.add(4);
    powers.add(2);
    powers.add(1);

    Scanner sc = new Scanner(System.in);
    System.out.println("Welcome to Paden9000 binary converter. Please enter an integer you wish to convert: ");
    int input = sc.nextInt();
    int printableInput = input;

    for (int i : powers) {
        if (input < i) {
            binaryStore.add(0);     
        } else {
            input = input - i;
            binaryStore.add(1);             
        }           
    }

    String newString= binaryStore.toString();
    String finalOutput = newString.replace("[", "")
            .replace(" ", "")
            .replace("]", "")
            .replace(",", "");

    System.out.println("Integer value: " + printableInput + "\nBinary value: " + finalOutput);
    sc.close();
}   

}

i put this code in my parent activity

List registeredReceivers = new ArrayList<>();

@Override
public Intent registerReceiver(BroadcastReceiver receiver, IntentFilter filter) {
    registeredReceivers.add(System.identityHashCode(receiver));
    return super.registerReceiver(receiver, filter);
}

@Override
public void unregisterReceiver(BroadcastReceiver receiver) {
    if(registeredReceivers.contains(System.identityHashCode(receiver)))
    super.unregisterReceiver(receiver);
}

This works for me.

<script languange="JavaScript">
     if (typeof module === 'object') {window.module = module; module = undefined;}
</script>

Things to consider:

1) Put this in section right before </head>

2) Include Jquery.min.js or Jquery.js right before the </body> tag

Instead of going with max-height: 100%/100%, an alternative approach of filling up all the space would be using position: absolute with top/bottom/left/right set to 0.

In other words, the HTML would look like the following:

<div class="flex-content">
  <div class="scrollable-content-wrapper">
    <div class="scrollable-content">
      1, 2, 3
    </div>
   </div>
</div>

.flex-content {
  flex-grow: 1;
  position: relative;
  width: 100%;
  height: 100%;
}

.scrollable-content-wrapper {
  position: absolute;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
  overflow: auto;
}

.scrollable-content {
}

You can see a live example at Codesandbox - Overflow within CSS Flex/Grid

If you have your project saved as a local copy of a repository, it may be better to import from git. Select local, and then browse to your git repository folder. That worked better for me than importing it as an existing project. Attempting the latter did not allow me to "finish".

The ideal way is to use a dictionary that maps a word to it's count. But if you can't use that, you might want to use 2 lists - 1 storing the words, and the other one storing counts of words. Note that order of words and counts matters here. Implementing this would be hard and not very efficient.

What you are talking about is called dot sourcing. And it's evil. But no worries, there is a better and easier way to do what you are wanting with modules (it sounds way scarier than it is). The major benefit of using modules is that you can unload them from the shell if you need to, and it keeps the variables in the functions from creeping into the shell (once you dot source a function file, try calling one of the variables from a function in the shell, and you'll see what I mean).

So first, rename the .ps1 file that has all your functions in it to MyFunctions.psm1 (you've just created a module!). Now for a module to load properly, you have to do some specific things with the file. First for Import-Module to see the module (you use this cmdlet to load the module into the shell), it has to be in a specific location. The default path to the modules folder is $home\Documents\WindowsPowerShell\Modules.

In that folder, create a folder named MyFunctions, and place the MyFunctions.psm1 file into it (the module file must reside in a folder with exactly the same name as the PSM1 file).

Once that is done, open PowerShell, and run this command:

Get-Module -listavailable

If you see one called MyFunctions, you did it right, and your module is ready to be loaded (this is just to ensure that this is set up right, you only have to do this once).

To use the module, type the following in the shell (or put this line in your $profile, or put this as the first line in a script):

Import-Module MyFunctions

You can now run your functions. The cool thing about this is that once you have 10-15 functions in there, you're going to forget the name of a couple. If you have them in a module, you can run the following command to get a list of all the functions in your module:

Get-Command -module MyFunctions

It's pretty sweet, and the tiny bit of effort that it takes to set up on the front side is WAY worth it.

Following this Microsoft Doc:

using System;
using System.Diagnostics;
using System.Threading;
class Program
{
    static void Main(string[] args)
    {
        Stopwatch stopWatch = new Stopwatch();
        stopWatch.Start();
        Thread.Sleep(10000);
        stopWatch.Stop();
        // Get the elapsed time as a TimeSpan value.
        TimeSpan ts = stopWatch.Elapsed;

        // Format and display the TimeSpan value.
        string elapsedTime = String.Format("{0:00}:{1:00}:{2:00}.{3:00}",
            ts.Hours, ts.Minutes, ts.Seconds,
            ts.Milliseconds / 10);
        Console.WriteLine("RunTime " + elapsedTime);
    }
}

Output: RunTime 00:00:09.94

Summarizing the most relevant comments in one answer:

• this is a known bug
• there are workarounds but you might not need them (read on)
• it happens when elements are placed directly inside the body, rather than inside a container-fluid div or another containing div. Placing them directly in the body is exactly what most people do when testing stuff locally. Once you place your code in the complete page (so within a container-fluid or another container div) you will not face this problem (no need to change anything).

If you look at the standard libraries the pattern generally is my_function, but every person does seem to have their own way :-/

return or return false are not the same as continue. If the loop is inside a function the remainder of the function will not execute as you would expect with a true "continue".

a new Q how to By a keys chain

dictionary1={'level1':{'level2':{'levelA':0,'levelB':1}},'anotherLevel1':{'anotherLevel2':{'anotherLevelA':0,'anotherLevelB':1}}}
update={'anotherLevel1':{'anotherLevel2':1014}}
dictionary1.update(update)
print dictionary1
{'level1':{'level2':{'levelA':0,'levelB':1}},'anotherLevel1':{'anotherLevel2':1014}}

Delete the existing one from KeyChain, get and add the .p12 file to your mac from where the certificate was created.

To get .p12 from source Mac, go to KeyChain, expand the certificate, select both and export 2 items. This will save .p12 file in your location:

The solution was to check the LoaderException: In my case, some of the DLL files were missing.

With Windows 8.1, you can now trust invalid SSL certs. You have to either use the Windows.Web.HttpClient or if you want to use the System.Net.Http.HttpClient, you can use the message handler adapter I wrote: http://www.nuget.org/packages/WinRtHttpClientHandler

Docs are on the GitHub: https://github.com/onovotny/WinRtHttpClientHandler

For production code requiring a large compatibility with client browsers I still suggest Ivan Nevostruev's answer above with shim to ensure Object.keys in older browsers. However, it's possible to get the exact functionality requested using ECMA's new defineProperty feature.

As of ECMAScript 5 - Object.defineProperty

As of ECMA5 you can use Object.defineProperty() to define non-enumerable properties. The current compatibility still has much to be desired, but this should eventually become usable in all browsers. (Specifically note the current incompatibility with IE8!)

Object.defineProperty(Object.prototype, 'keys', {
  value: function keys() {
    var keys = [];
    for(var i in this) if (this.hasOwnProperty(i)) {
      keys.push(i);
    }
    return keys;
  },
  enumerable: false
});

var o = {
    'a': 1,
    'b': 2
}

for (var k in o) {
    console.log(k, o[k])
}

console.log(o.keys())

# OUTPUT
# > a 1
# > b 2
# > ["a", "b"]

However, since ECMA5 already added Object.keys you might as well use:

Object.defineProperty(Object.prototype, 'keys', {
  value: function keys() {
    return Object.keys(this);
  },
  enumerable: false
});

Original answer

Object.prototype.keys = function ()
{
  var keys = [];
  for(var i in this) if (this.hasOwnProperty(i))
  {
    keys.push(i);
  }
  return keys;
}

Edit: Since this answer has been around for a while I'll leave the above untouched. Anyone reading this should also read Ivan Nevostruev's answer below.

There's no way of making prototype functions non-enumerable which leads to them always turning up in for-in loops that don't use hasOwnProperty. I still think this answer would be ideal if extending the prototype of Object wasn't so messy.

It might be that you have an expired development profile on your phone.

My development provisioning profile expired several days ago and I had to renew it. I installed the new profile on my phone and came up with the same error message when I tried to run my app. When I looked at the profile settings on my phone I noticed the expired profile and removed it. That cleared the error for me.

First, your jQuery will not work at all unless you enclose all your trs and tds in a table:

<table>
    <tr>...</tr>
    ...
</table>

Second, your code gets the id of the first tr of the page, since you select all the trs of the page and get the id of the first one (.attr() returns the attribute of the first element in the set of elements it is used on)

Your current code:

  $('input[type=button]' ).click(function() {
   bid = (this.id) ; // button ID 
   trid = $('tr').attr('id'); // ID of the the first TR on the page
                              // $('tr') selects all trs in the DOM
  });

trid is always TEST1 (jsFiddle)

Instead of selecting all trs on the page with $('tr'), you want to select the first ancestor of the clicked upon input that is a tr. Use .closest() for this in the form $(this).closest('tr').

You can reference the clicked on element as this, make a jQuery object out of it with the form $(this), so you have access to all the jQuery methods on it.

What your code should look like:

  // On DOM ready...
$(function() {

      $('input[type=button]' ).click(function() {

          var bid, trid; // Declare variables. If you don't use var 
                         // you will bind bid and trid 
                         // to the window, since you make them global variables.

          bid = (this.id) ; // button ID 

          trid = $(this).closest('tr').attr('id'); // table row ID 
      });
});

jsFiddle example

Based on what @J. Calleja said, you have two choices

Method 1 - Random access

If you want to random access the element of Mat, just simply use

Mat.at<data_Type>(row_num, col_num) = value;

Method 2 - Continuous access

If you want to continuous access, OpenCV provides Mat iterator compatible with STL iterator and it's more C++ style

MatIterator_<double> it, end;
for( it = I.begin<double>(), end = I.end<double>(); it != end; ++it)
{
    //do something here
}

or

for(int row = 0; row < mat.rows; ++row) {
    float* p = mat.ptr(row); //pointer p points to the first place of each row
    for(int col = 0; col < mat.cols; ++col) {
         *p++;  // operation here
    }
}

If you have any difficulty to understand how Method 2 works, I borrow the picture from a blog post in the article Dynamic Two-dimensioned Arrays in C, which is much more intuitive and comprehensible.

See the picture below.

Analyse the syntax of your project file. Check it inside your project in terminal:

plutil -lint project.pbxproj

This will show you the errors from the parser.

Possible problem: Some projects set git merging strategy union for project files. This works for most of the times, but will silently kill your project file if it fails. This strategy is defined in the .gitattributes file in your repository.

For a single column better to use map(), like this:

df = pd.DataFrame([{'a': 15, 'b': 15, 'c': 5}, {'a': 20, 'b': 10, 'c': 7}, {'a': 25, 'b': 30, 'c': 9}])

    a   b  c
0  15  15  5
1  20  10  7
2  25  30  9



df['a'] = df['a'].map(lambda a: a / 2.)

      a   b  c
0   7.5  15  5
1  10.0  10  7
2  12.5  30  9

Hibernate defines five types of identifier generation strategies:

AUTO - either identity column, sequence or table depending on the underlying DB

TABLE - table holding the id

IDENTITY - identity column

SEQUENCE - sequence

identity copy – the identity is copied from another entity

Example using Table

@Id
@GeneratedValue(strategy=GenerationType.TABLE , generator="employee_generator")
@TableGenerator(name="employee_generator", 
                table="pk_table", 
                pkColumnName="name", 
                valueColumnName="value",                            
                allocationSize=100) 
@Column(name="employee_id")
private Long employeeId;

I found success with the following, works with .zip
(Simplified here for posting: no error checking & just unzips all files to current folder)

function DownloadAndUnzip(URL){
    var unzip = require('unzip');
    var http = require('http');
    var request = http.get(URL, function(response) {
        response.pipe(unzip.Extract({path:'./'}))
    });
}

The good way to draw a Drawable on a canvas is not decoding it yourself but leaving it to the system to do so:

Drawable d = getResources().getDrawable(R.drawable.foobar, null);
d.setBounds(left, top, right, bottom);
d.draw(canvas);

This will work with all kinds of drawables, not only bitmaps. And it also means that you can re-use that same drawable again if only the size changes.

x(end+1) = newElem is a bit more robust.

x = [x newElem] will only work if x is a row-vector, if it is a column vector x = [x; newElem] should be used. x(end+1) = newElem, however, works for both row- and column-vectors.

In general though, growing vectors should be avoided. If you do this a lot, it might bring your code down to a crawl. Think about it: growing an array involves allocating new space, copying everything over, adding the new element, and cleaning up the old mess...Quite a waste of time if you knew the correct size beforehand :)

I'd probably split the long statement up into multiple shorter statements so that the program logic is separated from the definition of the long string:

>>> def fun():
...     format_string = '{0} Here is a really long ' \
...                     'sentence with {1}'
...     print format_string.format(3, 5)

If the string is only just too long and you choose a short variable name then by doing this you might even avoid having to split the string:

>>> def fun():
...     s = '{0} Here is a really long sentence with {1}'
...     print s.format(3, 5)

A private setter is useful if you have a read only property and don't want to explicitly declare the backing variable.

So:

public int MyProperty
{
    get; private set;
}

is the same as:

private int myProperty;
public int MyProperty
{
    get { return myProperty; }
}

For non auto implemented properties it gives you a consistent way of setting the property from within your class so that if you need validation etc. you only have it one place.

To answer your final question the MSDN has this to say on private setters:

However, for small classes or structs that just encapsulate a set of values (data) and have little or no behaviors, it is recommended to make the objects immutable by declaring the set accessor as private.

From the MSDN page on Auto Implemented properties

JavaScript only simple solution

The invalid hostname indicates that the actual site you configured in the IIS Express configuration file is (most likely) not running. IIS Express doesn't have a process model like IIS does.

For your site to run it would need to be started explicitly (either by opening and accessing from webmatrix, or from command line calling iisexpress.exe (from it's installation directory) with the /site parameter.

In general, the steps to allow fully qualified DNS names to be used for local access are Let's use your example of the DNS name dev.example.com

1. edit %windows%\system32\drivers\etc\hosts file to map dev.example.com to 127.0.0.1 (admin privilege required). If you control DNS server (like in Nick's case) then the DNS entry is sufficient as this step is not needed.
2. If you access internet through proxy, make sure the dev.example.com will not be forwared to proxy (you have to put in on the exception list in your browser (for IE it would be Tools/Internet Options/Connections/Lan Settings, then go to Proxy Server/Advanced and put dev.example.com on the exeption list.

3. Configure IIS Express binding for your site (eg:Site1) to include dev.example.com. Administrative privilege will be needed to use the binding. Alternatively, a one-time URL reservation can be made with http.sys using

   netsh http add urlacl url=http://dev.example.com:<port>/ user=<user_name>

4. start iisexpress /site:Site1 or open Site1 in WebMatrix

There was once an example in the SSL source in the directory demos/ssl/ with example code in C++. Now it's available only via the history: https://github.com/openssl/openssl/tree/691064c47fd6a7d11189df00a0d1b94d8051cbe0/demos/ssl

You probably will have to find a working version, I originally posted this answer at Nov 6 2015. And I had to edit the source -- not much.

The error seems clear: model objects do not support item assignment. MyModel.objects.latest('id')['foo'] = 'bar' will throw this same error.

It's a little confusing that your model instance is called projectForm...

To reproduce your first block of code in a loop, you need to use setattr

for k,v in session_results.iteritems():
    setattr(projectForm, k, v)

The following command will create a copy in a new window. So you can continue see both original file and the new file.

:w {newfilename} | sp #

Older versions of JSP did not support the second syntax.

Ok so the key for me was to use the .FlattenHierarchy BindingFlag. I don't really know why I just added it on a hunch and it started working. So the final solution that allows me to get Public Instance or Static Properties is:

obj.GetType.GetProperty(propName, Reflection.BindingFlags.Public _
  Or Reflection.BindingFlags.Static Or Reflection.BindingFlags.Instance Or _
  Reflection.BindingFlags.FlattenHierarchy)

in my problem I want the text of anchor <a>text</a> inside my view to be based on some value and that text is retrieved form App string Resources

so, this @() is the solution

<a href='#'>
      @(Model.ID == 0 ? Resource_en.Back : Resource_en.Department_View_DescartChanges)
</a>

if the text is not from App string Resources use this

@(Model.ID == 0 ? "Back" :"Descart Changes")

Making siliconerockstar's comment an answer since it worked for me

Try using rowMeans:

z$mean=rowMeans(z[,c("x", "y")], na.rm=TRUE)

  w x  y mean
1 5 1  1    1
2 6 2  2    2
3 7 3  3    3
4 8 4 NA    4

You can use contextual selectors and move the vertical-align there. This would work with the p tag, then. Take this snippet below as an example. Any p tags within your class will respect the vertical-align control:

#header_selecttxt {
    font-family: Arial;
    font-size: 12px;
    font-weight: bold;
}

#header_selecttxt p {
    vertical-align: text-top;
}

You could also keep the vertical-align in both sections so that other, inline elements would use this.

This is how you use bundle:

Bundle b = new Bundle();
b.putInt("id", id);
Fragment frag= new Fragment();
frag.setArguments(b);

retrieve value from bundle:

 bundle = getArguments();
 if (bundle != null) {
    id = bundle.getInt("id");
 }

RDBMS focus more on relationship and NoSQL focus more on storage.

You can consider using NoSQL when your RDBMS reaches bottlenecks. NoSQL makes RDBMS more flexible.

That depends on what you want to do, but as you said, getting an entity reference using find() and then just updating that entity is the easiest way to do that.

I'd not bother about performance differences of the various methods unless you have strong indications that this really matters.

For me the problem was that the app I was trying to launch was already installed under a different user account on my phone. I saw this when I went to Settings->apps looking to uninstall it. I switched to the other user, uninstalled it, came back to the original user, and was able to install and launch the app from Android Studio with no more problems.

SELECT col1, col2, IF( action = 2 AND state = 0, 1, 0 ) AS state from tbl1;

OR

SELECT col1, col2, (case when (action = 2 and state = 0) then 1 else 0 end) as state from tbl1;

both results will same....

If you are using App.Config to store values in <add Key="" Value="" /> or CustomSections section use ConfigurationManager class, else use XMLDocument class.

For example:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="server" value="192.168.0.1\xxx"/>
    <add key="database" value="DataXXX"/>
    <add key="username" value="userX"/>
    <add key="password" value="passX"/>
  </appSettings>
</configuration>

You could use the code posted on CodeProject

You can use array_count_values function

$array = array('apple', 'orange', 'pear', 'banana', 'apple',
'pear', 'kiwi', 'kiwi', 'kiwi');

print_r(array_count_values($array));

will output

Array
(
   [apple] => 2
   [orange] => 1
   [pear] => 2
   etc...
)

CONVERT style 103 is dd/mm/yyyy. Then use the REPLACE function to eliminate the slashes.

Maybe git mv has changed since these answers were posted, so I will update briefly. In my view, git mv is not accurately described as short hand for:

 # not accurate: #
 mv oldname newname
 git add newname
 git rm oldname

I use git mv frequently for two reasons that have not been described in previous answers:

1. Moving large directory structures, where I have mixed content of both tracked and untracked files. Both tracked and untracked files will move, and retain their tracking/untracking status

2. Moving files and directories that are large, I have always assumed that git mv will reduce the size of the repository DB history size. This is because moving/renaming a file is indexation/reference delta. I have not verified this assumption, but it seems logical.

I wrote this procedure inspired by Cherian's answer. The difference is that in my version the user name is an argument of the procedure ( and not hard coded ) . I'm also doing a much necessary FLUSH PRIVILEGES after dropping the user.

DROP PROCEDURE IF EXISTS DropUserIfExists;
DELIMITER $$
CREATE PROCEDURE DropUserIfExists(MyUserName VARCHAR(100))
BEGIN
  DECLARE foo BIGINT DEFAULT 0 ;
  SELECT COUNT(*)
  INTO foo
    FROM mysql.user
      WHERE User = MyUserName ;
   IF foo > 0 THEN
         SET @A = (SELECT Result FROM (SELECT GROUP_CONCAT("DROP USER"," ",MyUserName,"@'%'") AS Result) AS Q LIMIT 1);
         PREPARE STMT FROM @A;
         EXECUTE STMT;
         FLUSH PRIVILEGES;
   END IF;
END ;$$
DELIMITER ;

I also posted this code on the CodeReview website ( https://codereview.stackexchange.com/questions/15716/mysql-drop-user-if-exists )

I read comments on answer set as Okay. Most of the user are asking that the button and some links click should be allowed. Here one more line is added to the existing code that will work.

<script type="text/javascript">
  var hook = true;
  window.onbeforeunload = function() {
    if (hook) {

      return "Did you save your stuff?"
    }
  }
  function unhook() {
    hook=false;
  }

Call unhook() onClick for button and links which you want to allow. E.g.

<a href="#" onClick="unhook()">This link will allow navigation</a>

The problem is your query returned false meaning there was an error in your query. After your query you could do the following:

if (!$result) {
    die(mysqli_error($link));
}

Or you could combine it with your query:

$results = mysqli_query($link, $query) or die(mysqli_error($link));

That will print out your error.

Also... you need to sanitize your input. You can't just take user input and put that into a query. Try this:

$query = "SELECT * FROM shopsy_db WHERE name LIKE '%" . mysqli_real_escape_string($link, $searchTerm) . "%'";

In reply to: Table 'sookehhh_shopsy_db.sookehhh_shopsy_db' doesn't exist

Are you sure the table name is sookehhh_shopsy_db? maybe it's really like users or something.

It does look like you have web.xml in the right location, but even so, this error is often caused by the directory structure not matching what Maven expects to see. For example, if you start out with an Eclipse webapp that you are trying to build with Maven.

If that is the issue, a quick fix is to create a
src/main/java and a
src/main/webapp directory (and other directories if you need them) and just move your files.

Here is an overview of the maven directory layout: http://maven.apache.org/guides/introduction/introduction-to-the-standard-directory-layout.html

I solved the problem by adding the following dependency

<dependency>
    <groupId>javax.persistence</groupId>
    <artifactId>persistence-api</artifactId>
    <version>2.2</version>
</dependency>

Together with

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jdbc</artifactId>
</dependency>

Another solution:

$array = array('a' => 'a', 'b' => 'b', 'c' => 'c');
$lastItem = $array[(array_keys($array)[(count($array)-1)])];
echo $lastItem;

Make sure you're calling super() as the first thing in your constructor.

You should set this for setAuthorState method

class ManageAuthorPage extends Component {

  state = {
    author: { id: '', firstName: '', lastName: '' }
  };

  constructor(props) {
    super(props);
    this.handleAuthorChange = this.handleAuthorChange.bind(this);
  } 

  handleAuthorChange(event) {
    let {name: fieldName, value} = event.target;

    this.setState({
      [fieldName]: value
    });
  };

  render() {
    return (
      <AuthorForm
        author={this.state.author}
        onChange={this.handleAuthorChange}
      />
    );
  }
}

Another alternative based on arrow function:

class ManageAuthorPage extends Component {

  state = {
    author: { id: '', firstName: '', lastName: '' }
  };

  handleAuthorChange = (event) => {
    const {name: fieldName, value} = event.target;

    this.setState({
      [fieldName]: value
    });
  };

  render() {
    return (
      <AuthorForm
        author={this.state.author}
        onChange={this.handleAuthorChange}
      />
    );
  }
}

yes you can use MapView in v2... for further details you can get help from this

It's a long time since the question was posted, but I experienced the same issue in a similar scenario. I have a console application and I was consuming a web service and our IIS server where the webservice was placed has windows authentication (NTLM) enabled.

I followed this link and that fixed my problem. Here's the sample code for App.config:

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="Service1Soap">
                <security mode="TransportCredentialOnly">
                    <transport clientCredentialType="Ntlm" proxyCredentialType="None"
                        realm=""/>

A fun way to solve your problem could be coding an eval() function on your own! I've done it for you!

You can use FunctionSolver library simply by typing FunctionSolver.solveByX(function,value) inside your code. The function attribute is a String which represents the function you want to solve, the value attribute is the value of the independent variable of your function (which MUST be x).

If you want to solve a function which contains more than one independent variable, you can use FunctionSolver.solve(function,values) where the values attribute is an HashMap(String,Double) which contains all your independent attributes (as Strings) and their respective values (as Doubles).

Another piece of information: I've coded a simple version of FunctionSolver, so its supports only Math methods which return a double value and which accepts one or two double values as fields (just use FunctionSolver.usableMathMethods() if you're curious) (These methods are: bs, sin, cos, tan, atan2, sqrt, log, log10, pow, exp, min, max, copySign, signum, IEEEremainder, acos, asin, atan, cbrt, ceil, cosh, expm1, floor, hypot, log1p, nextAfter, nextDown, nextUp, random, rint, sinh, tanh, toDegrees, toRadians, ulp). Also, that library supports the following operators: * / + - ^ (even if java normally does not support the ^ operator).

One last thing: while creating this library I had to use reflections to call Math methods. I think it's really cool, just have a look at this if you are interested in!

That's all, here it is the code (and the library):

Today (2.5 years after this answer) you can safely use Array.forEach. As @ricosrealm suggests, decodeURIComponent was used in this function.

function getJsonFromUrl(url) {
  if(!url) url = location.search;
  var query = url.substr(1);
  var result = {};
  query.split("&").forEach(function(part) {
    var item = part.split("=");
    result[item[0]] = decodeURIComponent(item[1]);
  });
  return result;
}

actually it's not that simple, see the peer-review in the comments, especially:

• hash based routing (@cmfolio)
• array parameters (@user2368055)
• proper use of decodeURIComponent and non-encoded = (@AndrewF)
• non-encoded + (added by me)

For further details, see MDN article and RFC 3986.

Maybe this should go to codereview SE, but here is safer and regexp-free code:

function getJsonFromUrl(url) {
  if(!url) url = location.href;
  var question = url.indexOf("?");
  var hash = url.indexOf("#");
  if(hash==-1 && question==-1) return {};
  if(hash==-1) hash = url.length;
  var query = question==-1 || hash==question+1 ? url.substring(hash) : 
  url.substring(question+1,hash);
  var result = {};
  query.split("&").forEach(function(part) {
    if(!part) return;
    part = part.split("+").join(" "); // replace every + with space, regexp-free version
    var eq = part.indexOf("=");
    var key = eq>-1 ? part.substr(0,eq) : part;
    var val = eq>-1 ? decodeURIComponent(part.substr(eq+1)) : "";
    var from = key.indexOf("[");
    if(from==-1) result[decodeURIComponent(key)] = val;
    else {
      var to = key.indexOf("]",from);
      var index = decodeURIComponent(key.substring(from+1,to));
      key = decodeURIComponent(key.substring(0,from));
      if(!result[key]) result[key] = [];
      if(!index) result[key].push(val);
      else result[key][index] = val;
    }
  });
  return result;
}

This function can parse even URLs like

var url = "?foo%20e[]=a%20a&foo+e[%5Bx%5D]=b&foo e[]=c";
// {"foo e": ["a a",  "c",  "[x]":"b"]}

var obj = getJsonFromUrl(url)["foo e"];
for(var key in obj) { // Array.forEach would skip string keys here
  console.log(key,":",obj[key]);
}
/*
  0 : a a
  1 : c
  [x] : b
*/

document.referrer is not the same as the actual URL in all situations.

I have an application where I need to establish a frameset with 2 frames. One frame is known, the other is the page I am linking from. It would seem that document.referrer would be ideal because you would not have to pass the actual file name to the frameset document.

However, if you later change the bottom frame page and then use history.back() it does not load the original page into the bottom frame, instead it reloads document.referrer and as a result the frameset is gone and you are back to the original starting window.

Took me a little while to understand this. So in the history array, document.referrer is not only a URL, it is apparently the referrer window specification as well. At least, that is the best way I can understand it at this time.

The answers provided by Bohzo and Brabster will obviously work, but you could also just use:

rs3.getInt(1);

to get the value in the first, and in your case, only column.

I had exactly same problem but my fix was different - my company is encrypting all the files on my machines. After decrypting the file MSSQL did not have any issues to accessing and created the DB. Just right click .bak file -> Properties -> Advanced... -> Encrypt contents to secure data.

You can download a file/folder from github

Simply use: svn export <repo>/trunk/<folder>

Ex: svn export https://github.com/lodash/lodash/trunk/docs

Note: You may first list the contents of the folder in terminal using svn ls <repo>/trunk/folder

(yes, that's svn here. apparently in 2016 you still need svn to simply download some github files)

string keyName=@"HKEY_LOCAL_MACHINE\System\CurrentControlSet\services\pcmcia";
string valueName="Start";
if (Registry.GetValue(keyName, valueName, null) == null)
{
     //code if key Not Exist
}
else
{
     //code if key Exist
}

It doesn't. There's a vague equivalent:

mycol VARCHAR(10) NOT NULL CHECK (mycol IN('Useful', 'Useless', 'Unknown'))

There is an underlying buffer/stream that getchar() and friends read from. When you enter text, the text is stored in a buffer somewhere. getchar() can stream through it one character at a time. Each read returns the next character until it reaches the end of the buffer. The reason it's not asking you for subsequent characters is that it can fetch the next one from the buffer.

If you run your script and type directly into it, it will continue to prompt you for input until you press CTRL+D (end of file). If you call it like ./program < myInput where myInput is a text file with some data, it will get the EOF when it reaches the end of the input. EOF isn't a character that exists in the stream, but a sentinel value to indicate when the end of the input has been reached.

As an extra warning, I believe getchar() will also return EOF if it encounters an error, so you'll want to check ferror(). Example below (not tested, but you get the idea).

main() {
    int c;
    do {
        c = getchar();
        if (c == EOF && ferror()) {
            perror("getchar");
        }
        else {
            putchar(c);
        }
    }
    while(c != EOF);
}

Set a property for the current lesson: currentLesson. It will hold, obviously, the 'number' of the choosen lesson. On each button click, set the currentLesson value to 'number'/ order of the button, i.e. for the first button, it will be '1', for the second '2' and so on. Each button now can be disabled with [disabled] attribute, if it the currentLesson is not the same as it's order.

HTML

  <button  (click)="currentLesson = '1'"
         [disabled]="currentLesson !== '1'" class="primair">
           Start lesson</button>
  <button (click)="currentLesson = '2'"
         [disabled]="currentLesson !== '2'" class="primair">
           Start lesson</button>
 .....//so on

Typescript

currentLesson:string;

  classes = [
{
  name: 'string',
  level: 'string',
  code: 'number',
  currentLesson: '1'
}]

constructor(){
  this.currentLesson=this.classes[0].currentLesson
}

DEMO

Putting everything in a loop:

HTML

<div *ngFor="let class of classes; let i = index">
   <button [disabled]="currentLesson !== i + 1" class="primair">
           Start lesson {{i +  1}}</button>
</div>

Typescript

currentLesson:string;

classes = [
{
  name: 'Lesson1',
  level: 1,
  code: 1,
},{
  name: 'Lesson2',
  level: 1,
  code: 2,
},
{
  name: 'Lesson3',
  level: 2,
  code: 3,
}]

The difference between:

parser.add_argument("--debug", help="Debug", nargs='?', type=int, const=1, default=7)

and

parser.add_argument("--debug", help="Debug", nargs='?', type=int, const=1)

is thus:

myscript.py => debug is 7 (from default) in the first case and "None" in the second

myscript.py --debug => debug is 1 in each case

myscript.py --debug 2 => debug is 2 in each case

I believe enum have a .name() in its API, pretty simple to use like this example:

private int security;
public String security(){ return Security.values()[security].name(); }
public void setSecurity(int security){ this.security = security; }

    private enum Security {
            low,
            high
    }

With this you can simply call

yourObject.security() 

and it returns high/low as String, in this example

The normal practice is to HTML-escape any user-controlled data during redisplaying in JSP, not during processing the submitted data in servlet nor during storing in DB. In JSP you can use the JSTL (to install it, just drop jstl-1.2.jar in /WEB-INF/lib) <c:out> tag or fn:escapeXml function for this. E.g.

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
...
<p>Welcome <c:out value="${user.name}" /></p>

and

<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
...
<input name="username" value="${fn:escapeXml(param.username)}">

That's it. No need for a blacklist. Note that user-controlled data covers everything which comes in by a HTTP request: the request parameters, body and headers(!!).

If you HTML-escape it during processing the submitted data and/or storing in DB as well, then it's all spread over the business code and/or in the database. That's only maintenance trouble and you will risk double-escapes or more when you do it at different places (e.g. & would become & instead of & so that the enduser would literally see & instead of & in view. The business code and DB are in turn not sensitive for XSS. Only the view is. You should then escape it only right there in view.

SELECT  MIN(Date)  AS Date  FROM tbl_Employee /*To get First date Of Employee*/

getElementById("id").removeAttribute("style");

if you are using jQuery then

$("#id").removeClass("classname");

You can achieve quite a cool custom checkbox effect by using the new abilities that come with the :after and :before pseudo classes. The advantage to this, is: You don't need to add anything more to the DOM, just the standard checkbox.

Note this will only work for compatible browsers. I believe this is related to the fact that some browsers do not allow you to set :after and :before on input elements. Which unfortunately means for the moment only WebKit browsers are supported. Firefox + Internet Explorer will still allow the checkboxes to function, just unstyled, and this will hopefully change in the future (the code does not use vendor prefixes).

This is a WebKit browser solution only (Chrome, Safari, Mobile browsers)

Instead of what are you using currently:

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

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

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

Some might encounter this error (I got it while implementing PHP-MySQLi-JSON-Google Chart Example):

You called the draw() method with the wrong type of data rather than a DataTable or DataView.

The solution would be: replace jsapi and just use loader.js with:

google.charts.load('current', {packages: ['corechart']}) and 
google.charts.setOnLoadCallback 

-- according to the release notes --> The version of Google Charts that remains available via the jsapi loader is no longer being updated consistently. Please use the new gstatic loader from now on.

The only thing I see is that it's supposed to be since Midnight Jan 1, 1970 UTC

TimeSpan span= DateTime.Now.Subtract(new DateTime(1970,1,1,0,0,0, DateTimeKind.Utc));
return span.TotalSeconds;

This is how I got it working with loading remote content that needs to be refreshed:

$(document).ready(function () {
    var loadingContent = '<div class="modal-header"><h1>Processing...</h1></div><div class="modal-body"><div class="progress progress-striped active"><div class="bar" style="width: 100%;"></div></div></div>';

    // This is need so the content gets replaced correctly.
    $("#myModal").on("show.bs.modal", function (e) {
        $(this).find(".modal-content").html(loadingContent);        
        var link = $(e.relatedTarget);
        $(this).find(".modal-content").load(link.attr("href"));
    });    

    $("#myModal2").on("hide.bs.modal", function (e) {
        $(this).removeData('bs.modal');
    });
});

Basically, just replace the modal content while it's loading with a loading message. The content will then be replaced once it's finished loading.

How about:

$timezone = new DateTimeZone('UTC');
$date = new DateTime('2011-04-21 13:14', $timezone);
echo $date->format;

Just use CR to go to beginning of the line.

import time
for x in range (0,5):  
    b = "Loading" + "." * x
    print (b, end="\r")
    time.sleep(1)

For me android:gravity="center" did the trick in the parent layout element.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/fullImageView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:adjustViewBounds="true"
        android:contentDescription="@string/fullImageView"
        android:layout_gravity="center" />

</LinearLayout>

Suppose ListView object is lv, do the following-

lv.setClickable(true);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {

  @Override
  public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {

    Object o = lv.getItemAtPosition(position);
    /* write you handling code like...
    String st = "sdcard/";
    File f = new File(st+o.toString());
    // do whatever u want to do with 'f' File object
    */  
  }
});

Try this:

<?php
    echo "<script> var x = " . json_encode($phpVariable) . "</script>";
?>

Although it works, however it slows down the performance. As PHP is a server-side script while JavaScript is a user side.

To add to wflynny's answer above, you can find the available colormaps here

Example:

import matplotlib.cm as cm
plt.scatter(x, y, c=t, cmap=cm.jet)

or alternatively,

plt.scatter(x, y, c=t, cmap='jet')

The simple solution has been well covered: take two random5 samples for one random7 result and do it over if the result is outside the range that generates a uniform distribution. If your goal is to reduce the number of calls to random5 this is extremely wasteful - the average number of calls to random5 for each random7 output is 2.38 rather than 2 due to the number of thrown away samples.

You can do better by using more random5 inputs to generate more than one random7 output at a time. For results calculated with a 31-bit integer, the optimum comes when using 12 calls to random5 to generate 9 random7 outputs, taking an average of 1.34 calls per output. It's efficient because only 2018983 out of 244140625 results need to be scrapped, or less than 1%.

Demo in Python:

def random5():
    return random.randint(1, 5)

def random7gen(n):
    count = 0
    while n > 0:
        samples = 6 * 7**9
        while samples >= 6 * 7**9:
            samples = 0
            for i in range(12):
                samples = samples * 5 + random5() - 1
                count += 1
        samples //= 6
        for outputs in range(9):
            yield samples % 7 + 1, count
            samples //= 7
            count = 0
            n -= 1
            if n == 0: break

>>> from collections import Counter
>>> Counter(x for x,i in random7gen(10000000))
Counter({2: 1430293, 4: 1429298, 1: 1428832, 7: 1428571, 3: 1428204, 5: 1428134, 6: 1426668})
>>> sum(i for x,i in random7gen(10000000)) / 10000000.0
1.344606

Because the first option is already selected, the change event is never fired. Add an empty value as the first one and check for empty in the location assignment.

Here's an example:

https://jsfiddle.net/bL5sq/

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">_x000D_
  <option value="">Select...</option>_x000D_
  <option value="https://google.com">Google</option>_x000D_
  <option value="https://yahoo.com">Yahoo</option>_x000D_
</select>

Prepare MANIFEST.MF file with the following content

Manifest-Version: 1.0
Main-Class: org.testng.TestNG

Pack all test and dependency classes in the same jar, say tests.jar

jar cmf MANIFEST.MF tests.jar -C folder-with-classes/ .

Notice trailing ".", replace folder-with-classes/ with proper folder name or path.

Create testng.xml with content like below

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="Tests" verbose="5">
  <test name="Test1">
    <classes>
      <class name="com.example.yourcompany.qa.Test1"/>
    </classes>
  </test>  
</suite>

Replace com.example.yourcompany.qa.Test1 with path to your Test class.

Run your tests

java -jar tests.jar testng.xml

If you want to set a date, DateTimePicker.Value is a DateTime object.

DateTimePicker.Value = new DateTime(2012,05,28);

This is the constructor of DateTime:

new DateTime(int year,int month,int date);

My Visual is 2012

No easy way. But for example:

seq -s= 100|tr -d '[:digit:]'

Or maybe a standard-conforming way:

printf %100s |tr " " "="

There's also a tput rep, but as for my terminals at hand (xterm and linux) they don't seem to support it:)

You can try this code. This is Simple PHP Image Deleting code from the server.

<form method="post">
<input type="text" name="photoname"> // You can type your image name here...
<input type="submit" name="submit" value="Delete">
</form>

<?php
if (isset($_POST['submit'])) 
{
$photoname = $_POST['photoname'];
if (!unlink($photoname))
  {
  echo ("Error deleting $photoname");
  }
else
  {
  echo ("Deleted $photoname");
  }
}
?>

I know the OP was asking about doing the export from the command line, but just in case this is helpful to anyone else out there...

You could just let Eclipse (plus one of the plugins discussed here) do the work for you.

Obviously, downloading Eclipse just for doing a single export is overkill, but if you are already using it for development, you can also do an svn export simply from your IDE's context menu when browsing an SVN repository.

Advantages:

• easier for those not so familiar with using SVN at the command-line level (but you can learn about what happens at the command-line level by looking at the SVN console with a range of commands)
• you'd already have your SVN details set up and wouldn't have to worry about authenticating, etc.
• you don't have to worry about mistyping the URL, or remembering the order of parameters
• you can specify in a dialog which directory you'd like to export to
• you can specify in a dialog whether you'd like to export from TRUNK/HEAD or use a specific revision

Yes.

while read in; do chmod 755 "$in"; done < file.txt

This way you can avoid a cat process.

cat is almost always bad for a purpose such as this. You can read more about Useless Use of Cat.

In my case I was missing mysql-server. So after installing it via sudo apt-get install mysql-server I was able to connect again.

Here's how I do it:

1. create file
2. send file to client
3. remove file

Code:

let fs = require('fs');
let path = require('path');

let myController = (req, res) => {
  let filename = 'myFile.ext';
  let absPath = path.join(__dirname, '/my_files/', filename);
  let relPath = path.join('./my_files', filename); // path relative to server root

  fs.writeFile(relPath, 'File content', (err) => {
    if (err) {
      console.log(err);
    }
    res.download(absPath, (err) => {
      if (err) {
        console.log(err);
      }
      fs.unlink(relPath, (err) => {
        if (err) {
          console.log(err);
        }
        console.log('FILE [' + filename + '] REMOVED!');
      });
    });
  });
};

Start mysql server by command prompt

C:> "C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqld" --console

Or alternative reach up to bin then

mysqld --console

It will start your server.

If you have mysql command line client available

click on it

it show enter your password :

Please enter your password.

Then you can access it.

the best way

map.off();
map.remove();

You should add map.off(), it also works faster, and does not cause problems with the events

The ApplicationPoolIdentity is assigned membership of the Users group as well as the IIS_IUSRS group. On first glance this may look somewhat worrying, however the Users group has somewhat limited NTFS rights.

For example, if you try and create a folder in the C:\Windows folder then you'll find that you can't. The ApplicationPoolIdentity still needs to be able to read files from the windows system folders (otherwise how else would the worker process be able to dynamically load essential DLL's).

With regard to your observations about being able to write to your c:\dump folder. If you take a look at the permissions in the Advanced Security Settings, you'll see the following:

See that Special permission being inherited from c:\:

That's the reason your site's ApplicationPoolIdentity can read and write to that folder. That right is being inherited from the c:\ drive.

In a shared environment where you possibly have several hundred sites, each with their own application pool and Application Pool Identity, you would store the site folders in a folder or volume that has had the Users group removed and the permissions set such that only Administrators and the SYSTEM account have access (with inheritance).

You would then individually assign the requisite permissions each IIS AppPool\[name] requires on it's site root folder.

You should also ensure that any folders you create where you store potentially sensitive files or data have the Users group removed. You should also make sure that any applications that you install don't store sensitive data in their c:\program files\[app name] folders and that they use the user profile folders instead.

So yes, on first glance it looks like the ApplicationPoolIdentity has more rights than it should, but it actually has no more rights than it's group membership dictates.

An ApplicationPoolIdentity's group membership can be examined using the SysInternals Process Explorer tool. Find the worker process that is running with the Application Pool Identity you're interested in (you will have to add the User Name column to the list of columns to display:

For example, I have a pool here named 900300 which has an Application Pool Identity of IIS APPPOOL\900300. Right clicking on properties for the process and selecting the Security tab we see:

As we can see IIS APPPOOL\900300 is a member of the Users group.

The best way to describe a table such as a column, type, modifiers of columns, etc.

\d+ tablename or \d tablename

On strings and memory allocation:

A string in C is just a sequence of chars, so you can use char * or a char array wherever you want to use a string data type:

typedef struct     {
  int number;
  char *name;
  char *address;
  char *birthdate;
  char gender;
} patient;

Then you need to allocate memory for the structure itself, and for each of the strings:

patient *createPatient(int number, char *name, 
  char *addr, char *bd, char sex) {

  // Allocate memory for the pointers themselves and other elements
  // in the struct.
  patient *p = malloc(sizeof(struct patient));

  p->number = number; // Scalars (int, char, etc) can simply be copied

  // Must allocate memory for contents of pointers.  Here, strdup()
  // creates a new copy of name.  Another option:
  // p->name = malloc(strlen(name)+1);
  // strcpy(p->name, name);
  p->name = strdup(name);
  p->address = strdup(addr);
  p->birthdate = strdup(bd);
  p->gender = sex;
  return p;
}

If you'll only need a few patients, you can avoid the memory management at the expense of allocating more memory than you really need:

typedef struct     {
  int number;
  char name[50];       // Declaring an array will allocate the specified
  char address[200];   // amount of memory when the struct is created,
  char birthdate[50];  // but pre-determines the max length and may
  char gender;         // allocate more than you need.
} patient;

On linked lists:

In general, the purpose of a linked list is to prove quick access to an ordered collection of elements. If your llist contains an element called num (which presumably contains the patient number), you need an additional data structure to hold the actual patients themselves, and you'll need to look up the patient number every time.

Instead, if you declare

typedef struct llist
{
  patient *p;
  struct llist *next;
} list;

then each element contains a direct pointer to a patient structure, and you can access the data like this:

patient *getPatient(list *patients, int num) {
  list *l = patients;
  while (l != NULL) {
    if (l->p->num == num) {
      return l->p;
    }
    l = l->next;
  }
  return NULL;
}

I remove/Rename .gradle folder in c:\users\Myuser\.gradle and restart Android Studio and worked for me

if the other div is sibling/child, or any combination of, of the parent yes

    .showme{ _x000D_
        display: none;_x000D_
    }_x000D_
    .showhim:hover .showme{_x000D_
        display : block;_x000D_
    }_x000D_
    .showhim:hover .hideme{_x000D_
        display : none;_x000D_
    }_x000D_
    .showhim:hover ~ .hideme2{ _x000D_
        display:none;_x000D_
    }

    <div class="showhim">_x000D_
        HOVER ME_x000D_
        <div class="showme">hai</div> _x000D_
        <div class="hideme">bye</div>_x000D_
    </div>_x000D_
    <div class="hideme2">bye bye</div>

If you want to use the call operator, the arguments can be an array stored in a variable:

$prog = 'c:\windows\system32\cmd.exe'
$myargs = '/c','dir','/x'
& $prog $myargs

The call operator works with ApplicationInfo objects too.

$prog = get-command cmd
$myargs = -split '/c dir /x'
& $prog $myargs

If you are using a Form Control, you can get the same property as ActiveX by using OLEFormat.Object property of the Shape Object. Better yet assign it in a variable declared as OptionButton to get the Intellisense kick in.

Dim opt As OptionButton

With Sheets("Sheet1") ' Try to be always explicit
    Set opt = .Shapes("Option Button 1").OLEFormat.Object ' Form Control
    Debug.Pring opt.Value ' returns 1 (true) or -4146 (false)
End With

But then again, you really don't need to know the value.
If you use Form Control, you associate a Macro or sub routine with it which is executed when it is selected. So you just need to set up a sub routine that identifies which button is clicked and then execute a corresponding action for it.

For example you have 2 Form Control Option Buttons.

Sub CheckOptions()
    Select Case Application.Caller
    Case "Option Button 1"
    ' Action for option button 1
    Case "Option Button 2"
    ' Action for option button 2
    End Select
End Sub

In above code, you have only one sub routine assigned to both option buttons.
Then you test which called the sub routine by checking Application.Caller.
This way, no need to check whether the option button value is true or false.

I'm writing logs to the files, which are generate on daily basis (per day one log file is getting generated). This approach is working fine for me :

var (
    serverLogger *log.Logger
)

func init() {
    // set location of log file
    date := time.Now().Format("2006-01-02")
    var logpath = os.Getenv(constant.XDirectoryPath) + constant.LogFilePath + date + constant.LogFileExtension
    os.MkdirAll(os.Getenv(constant.XDirectoryPath)+constant.LogFilePath, os.ModePerm)
    flag.Parse()
    var file, err1 = os.OpenFile(logpath, os.O_RDWR|os.O_CREATE|os.O_APPEND, 0666)

    if err1 != nil {
        panic(err1)
    }
    mw := io.MultiWriter(os.Stdout, file)
    serverLogger = log.New(mw, constant.Empty, log.LstdFlags)
    serverLogger.Println("LogFile : " + logpath)
}

// LogServer logs to server's log file
func LogServer(logLevel enum.LogLevel, message string) {
    _, file, no, ok := runtime.Caller(1)
    logLineData := "logger_server.go"
    if ok {
        file = shortenFilePath(file)
        logLineData = fmt.Sprintf(file + constant.ColonWithSpace + strconv.Itoa(no) + constant.HyphenWithSpace)
    }
    serverLogger.Println(logLineData + logLevel.String() + constant.HyphenWithSpace + message)
}

// ShortenFilePath Shortens file path to a/b/c/d.go tp d.go
func shortenFilePath(file string) string {
    short := file
    for i := len(file) - 1; i > 0; i-- {
        if file[i] == constant.ForwardSlash {
            short = file[i+1:]
            break
        }
    }
    file = short
    return file
}

"shortenFilePath()" method used to get the name of the file from full path of file. and "LogServer()" method is used to create a formatted log statement (contains : filename, line number, log level, error statement etc...)

$percentage = 50;
$totalWidth = 350;

$new_width = ($percentage / 100) * $totalWidth;

Another possible way:

open my $fh, '<', "filename";
read $fh, my $string, -s $fh;
close $fh;

Most solutions work fine here. Would like to show another, similar alternative :

gradle:

implementation 'androidx.appcompat:appcompat:1.0.0-rc02'
implementation 'com.google.android.material:material:1.0.0-rc02'
implementation 'androidx.core:core-ktx:1.0.0-rc02'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

You layout can have a Toolbar View, and a shadow for it, below, similar to this (need modification of course) :

<LinearLayout

MainActivity.kt

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {

}

Full sample here, as I've noticed the IDE has a bug of saying foreground attribute is too new to be used here.

span.middle {
    margin: 0 10px 0 10px; /*top right bottom left */
}

<span>text</span> <span class="middle">text</span> <span>text</span>

If you are declaring your pipe in another module, make sure to add it to that module Declarations and Exports array, then import that module in whatever module is consuming that pipe.

just put height="400px" into image attribute like

<img class="d-block w-100" src="../assets/img/natural-backdrop.jpg" height="400px" alt="First slide">

As others have noted, most likely you don't have .html set up to handle php code.

Having said that, if all you're doing is using index.html to include index.php, your question should probably be 'how do I use index.php as index document?

In which case, for Apache (httpd.conf), search for DirectoryIndex and replace the line with this (will only work if you have dir_module enabled, but that's default on most installs):

DirectoryIndex index.php

If you use other directory indexes, list them in order of preference i.e.

DirectoryIndex index.php index.phtml index.html index.htm

.success() only gets called if your webserver responds with a 200 OK HTTP header - basically when everything is fine.

The callbacks attached to done() will be fired when the deferred is resolved. The callbacks attached to fail() will be fired when the deferred is rejected.

promise.done(doneCallback).fail(failCallback)

.done() has only one callback and it is the success callback

setattr(x, attr, 'magic')

For help on it:

>>> help(setattr)
Help on built-in function setattr in module __builtin__:

setattr(...)
    setattr(object, name, value)

    Set a named attribute on an object; setattr(x, 'y', v) is equivalent to
    ``x.y = v''.

Edit: However, you should note (as pointed out in a comment) that you can't do that to a "pure" instance of object. But it is likely you have a simple subclass of object where it will work fine. I would strongly urge the O.P. to never make instances of object like that.
