According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

df['name'].value_counts()[:5].sort_values(ascending=False)

The value_counts will return a count object of pandas.core.series.Series and sort_values(ascending=False) will get you the highest values first.

Restarting Xcode worked for me (quit and start again).

What didn't work for me:

• waiting for an hour on one device
• waiting for an hour on another device
• restarting devices
• unpairing/pairing devices

Try hitting the URL with "https://" instead of "http://"

Things have been changed after conda 4.6.

Programs "Anaconda Prompt" and "Anaconda Powershell" expose the command conda for you automatically. Find them in your startup menu.

If you don't wanna use the prompts above and try to make conda available in a normal cmd.exe and a Powershell. Read the following content.

Expose conda in Every Shell

The purpose of the following content is to make command conda available both in cmd.exe and Powershell on Windows.

If you have already checked "Add Anaconda to my PATH environment variable" during Anaconda installation, skip step 1.

1. If Anaconda is installed for the current use only, add %USERPROFILE%\Anaconda3\condabin (I mean condabin, not Scripts) into the environment variable PATH (the user one). If Anaconda is installed for all users on your machine, add C:\ProgramData\Anaconda3\condabin into PATH.

   How do I set system environment variables on Windows?

2. Open a new Powershell, run the following command once to initialize conda.

   conda init
   

These steps make sure the conda command is exposed into your cmd.exe and Powershell.

Extended Reading: conda init from Conda 4.6

Caveat: Add the new \path\to\anaconda3\condabin but not \path\to\anaconda3\Scripts into your PATH. This is a big change introduced in conda 4.6.

Activation script initialization fron conda 4.6 release log

Conda 4.6 adds extensive initialization support so that more shells than ever before can use the new conda activate command. For more information, read the output from conda init –help We’re especially excited about this new way of working, because removing the need to modify PATH makes Conda much less disruptive to other software on your system.

In the old days, \path\to\anaconda3\Scripts is the one to be put into your PATH. It exposes command conda and the default Python from "base" environment at the same time.

After conda 4.6, conda related commands are separated into condabin. This makes it possible to expose ONLY command conda without activating the Python from "base" environment.

For me, the error was a result of a third-party library that I imported that used older Google Support Library modules. I simply updated them to the latest version (checking on Github for example), and the error was gone. I suggest checking all the non-Google libraries that you included in your build.gradle are up to date.

Louis' answer is great, but I thought I would try to sum it up succinctly:

The bang operator tells the compiler to temporarily relax the "not null" constraint that it might otherwise demand. It says to the compiler: "As the developer, I know better than you that this variable cannot be null right now".

I would avoid using a relative path. Remember that docker is a daemon/client relationship.

When you are executing the compose, it's essentially just breaking down into various docker client commands, which are then passed to the daemon. That ./database is then relative to the daemon, not the client.

Now, the docker dev team has some back and forth on this issue, but the bottom line is it can have some unexpected results.

In short, don't use a relative path, use an absolute path.

Yet another way to do it:

//Where $file is an instance of Illuminate\Http\UploadFile
$extension = $file->getClientOriginalExtension();

Well in my case i was accessing an static array of a class by reference of that class, but as we know we can directly access static member via class name. So when I replaced reference with class name where I was accessing that array. It fixed this error.

If you want this type of code to run in IE11 (which does not support much of ES6 at all), then you need to get a 3rd party promise library (like Bluebird), include that library and change your coding to use ES5 coding structures (no arrow functions, no let, etc...) so you can live within the limits of what older browsers support.

Or, you can use a transpiler (like Babel) to convert your ES6 code to ES5 code that will work in older browsers.

Here's a version of your code written in ES5 syntax with the Bluebird promise library:

<script src="https://cdnjs.cloudflare.com/ajax/libs/bluebird/3.3.4/bluebird.min.js"></script>

<script>

'use strict';

var promise = new Promise(function(resolve) {
    setTimeout(function() {
        resolve("result");
    }, 1000);
});

promise.then(function(result) {
    alert("Fulfilled: " + result);
}, function(error) {
    alert("Rejected: " + error);
});

</script>

NO NEED FOR MULTIDEX, I REPEAT, NO NEEED FOR MULTIDEX

Let me elaborate: Multidex is basically a tool that comes with Android, and if you set it to true, apps with >64,000 methods are able to compile using a slightly altered build process. However you only need to use multidex if your error looks like this:

trouble writing output: Too many field references: 131000; max is 65536. You may try using --multi-dex option.

or like this

Conversion to Dalvik format failed: Unable to execute dex: method ID not in [0, 0xffff]: 65536

But that is not the case here! The problem here (for me atleast) is being caused by your build.gradle file's dependencies.

THE SOLUTION: Utilize specific dependencies—don't just import an entire section of dependencies!

For example, if you need the Play Services dependency for location, only import it for location.

DO:

compile 'com.google.android.gms:play-services-location:11.0.4'

DON'T:

compile 'com.google.android.gms:play-services'

Another issue that could be causing this may be some sort of external library you are using, that is referencing a prior version of your dependency. Follow these steps in that case:

1. Go to SDK manager, and install any updates to your dependencies
2. Make sure that your build.gradle file shows the latest version. To get the latest version, use this link: https://developers.google.com/android/guides/setup
3. Edit your library (or install an updated version if that exists), to reference the latest version

I know this question is old, but I need to get this answer out there, because using multidex for no reason could potentially cause ANR's for your app! ONLY use multidex if you're sure you need it, and you understand what it is.

I myself spent hours trying to resolve this issue without multidex, and I just wanted to share my findings—hope this helps

In my case when i tried

$ hive --service metastore 

I got

MetaException(message:Version information not found in metastore. )

The necessary tables required for the metastore are missing in MySQL. Manually create the tables and restart hive metastore.

cd $HIVE_HOME/scripts/metastore/upgrade/mysql/ 

< Login into MySQL > 

mysql> drop database IF EXISTS <metastore db name>; 
mysql> create database <metastore db name>; 
mysql> use <metastore db name>; 
mysql> source hive-schema-2.x.x.mysql.sql; 

metastore db name should match the database name mentioned in hive-site.xml files connection property tag.

hive-schema-2.x.x.mysql.sql file depends on the version available in the current directory. Try to go for the latest because it holds many old schema files also.

Now try to execute hive --service metastore If everything goes cool, then simply start the hive from terminal.

>hive

I hope the above answer serves your need.

I resolved the issue by double checking the "libs" directory and removing redundant jars, even though those jars were not manually added in the dependencies.

I think a solution is to put count in back ticks

.filter("`count` >= 2")

http://mail-archives.us.apache.org/mod_mbox/spark-user/201507.mbox/%3C8E43A71610EAA94A9171F8AFCC44E351B48EDF@fmsmsx124.amr.corp.intel.com%3E

The Maximum execution time of 30 seconds exceeded error is not related to Laravel but rather your PHP configuration.

Here is how you can fix it. The setting you will need to change is max_execution_time.

;;;;;;;;;;;;;;;;;;;
; Resource Limits ;
;;;;;;;;;;;;;;;;;;;

max_execution_time = 30     ; Maximum execution time of each script, in seconds
max_input_time = 60 ; Maximum amount of time each script may spend parsing request data
memory_limit = 8M      ; Maximum amount of memory a script may consume (8MB)

You can change the max_execution_time to 300 seconds like max_execution_time = 300

You can find the path of your PHP configuration file in the output of the phpinfo function in the Loaded Configuration File section.

I've created a pared-down demo project for you.

• Source: https://github.com/bigfont/webapi-cors
• Api Link: https://cors-webapi.azurewebsites.net/api/values

You can try the above API Link from your local Fiddler to see the headers. Here is an explanation.

Global.ascx

All this does is call the WebApiConfig. It's nothing but code organization.

public class WebApiApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        WebApiConfig.Register(GlobalConfiguration.Configuration);
    }
}

WebApiConfig.cs

The key method for your here is the EnableCrossSiteRequests method. This is all that you need to do. The EnableCorsAttribute is a globally scoped CORS attribute.

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        EnableCrossSiteRequests(config);
        AddRoutes(config);
    }

    private static void AddRoutes(HttpConfiguration config)
    {
        config.Routes.MapHttpRoute(
            name: "Default",
            routeTemplate: "api/{controller}/"
        );
    }

    private static void EnableCrossSiteRequests(HttpConfiguration config)
    {
        var cors = new EnableCorsAttribute(
            origins: "*", 
            headers: "*", 
            methods: "*");
        config.EnableCors(cors);
    }
}

Values Controller

The Get method receives the EnableCors attribute that we applied globally. The Another method overrides the global EnableCors.

public class ValuesController : ApiController
{
    // GET api/values
    public IEnumerable<string> Get()
    {
        return new string[] { 
            "This is a CORS response.", 
            "It works from any origin." 
        };
    }

    // GET api/values/another
    [HttpGet]
    [EnableCors(origins:"http://www.bigfont.ca", headers:"*", methods: "*")]
    public IEnumerable<string> Another()
    {
        return new string[] { 
            "This is a CORS response. ", 
            "It works only from two origins: ",
            "1. www.bigfont.ca ",
            "2. the same origin." 
        };
    }
}

Web.config

You do not need to add anything special into web.config. In fact, this is what the demo's web.config looks like - it's empty.

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

Demo

var url = "https://cors-webapi.azurewebsites.net/api/values"_x000D_
_x000D_

  console.log(status);_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

you can try something like this

set the parent to rotate and the image to scale so that the rotate and scale time can be different

.image {_x000D_
  position: absolute;_x000D_
  top: 50%;_x000D_

easy way to do it: To get the actual user count:

$ADInfo = Get-ADGroup -Identity '<groupname>' -Properties Members
$AdInfo.Members.Count

and you get the count easily, it is pretty fast as well for 20k+ users too

Make sure your solutions startup project has the correct connectionstring in the config file. Or set the -StartUpProjectName parameter when executing the update-database command. The -StartUpProjectName parameter specifies the configuration file to use for named connection strings. If omitted, the specified project’s configuration file is used.

Here is a link for ef-migration command references http://coding.abel.nu/2012/03/ef-migrations-command-reference/

Add this to build.gradle file

dexOptions {
   javaMaxHeapSize "2g"
}

Building on what is mentioned in the comments, the simplest solution would be:

@RequestMapping(method = RequestMethod.PUT, consumes = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public Collection<BudgetDTO> updateConsumerBudget(@RequestBody SomeDto someDto) throws GeneralException, ParseException {

    //whatever

}

class SomeDto {

   private List<WhateverBudgerPerDateDTO> budgetPerDate;


  //getters setters
}

The solution assumes that the HTTP request you are creating actually has

Content-Type:application/json instead of text/plain

url:

http://0.0.0.0:5000/user/name/

code:

@app.route('/user/<string:name>/', methods=['GET', 'POST'])
def user_view(name):
    print(name)

(Edit: removed spaces in format string)

When using Jest 21.2.1, I can see code coverage at the command line and create a coverage directory by passing --coverage to the Jest script. Below are some examples:

I tend to install Jest locally, in which case the command might look like this:

npx jest --coverage

I assume (though haven't confirmed), that this would also work if I installed Jest globally:

jest --coverage

The very sparse docs are here

When I navigated into the coverage/lcov-report directory I found an index.html file that could be loaded into a browser. It included the information printed at the command line, plus additional information and some graphical output.

You can simplify your code down to

url = "http://worldcup.kimonolabs.com/api/players?apikey=xxx"
json_obj = urllib2.urlopen(url).read
player_json_list = json.loads(json_obj)
for player in readable_json_list:
    print player['firstName']

You were trying to access a list element using dictionary syntax. the equivalent of

foo = [1, 2, 3, 4]
foo["1"]

It can be confusing when you have lists of dictionaries and keeping the nesting in order.

If you have a look at Preferences -> General you will notice at the bottom of the panel, there is a setting Load preferences from a custom folder or URL:. There is a button next to it Save settings to Folder.

So all you need to do is save your settings first and load it after you reinstalled your OS.

If the Save settings to Folder is disabled, select a folder (e.g. empty) in the Load preferences from a custom folder or URL: text box.

In iTerm2 3.3 on OSX the sequence is: iTerm2 menu, Preferences, General tab, Preferences subtab

* offsetHeight is a measurement in pixels of the element's CSS height, including border, padding and the element's horizontal scrollbar.

* clientHeight property returns the viewable height of an element in pixels, including padding, but not the border, scrollbar or margin.

* scrollHeight value is equal to the minimum height the element would require in order to fit all the content in the viewport without using a vertical scrollbar. The height is measured in the same way as clientHeight: it includes the element's padding, but not its border, margin or horizontal scrollbar.

Same is the case for all of these with width instead of height.

When you import a module (or a member of it) for the first time, the code inside the module is executed sequentially like any other code; e.g., it is not treated any differently that the body of a function. An import is just a command like any other (assignment, a function call, def, class). Assuming your imports occur at the top of the script, then here's what's happening:

• When you try to import World from world, the world script gets executed.
• The world script imports Field, which causes the entities.field script to get executed.
• This process continues until you reach the entities.post script because you tried to import Post
• The entities.post script causes physics module to be executed because it tries to import PostBody
• Finally, physics tries to import Post from entities.post
• I'm not sure whether the entities.post module exists in memory yet, but it really doesn't matter. Either the module is not in memory, or the module doesn't yet have a Post member because it hasn't finished executing to define Post
• Either way, an error occurs because Post is not there to be imported

So no, it's not "working further up in the call stack". This is a stack trace of where the error occurred, which means it errored out trying to import Post in that class. You shouldn't use circular imports. At best, it has negligible benefit (typically, no benefit), and it causes problems like this. It burdens any developer maintaining it, forcing them to walk on egg shells to avoid breaking it. Refactor your module organization.

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

In Bash:

for i in `sudo docker images|grep \<none\>|awk '{print $3}'`;do sudo docker rmi $i;done

This will remove all images with name "<none>". I found those images redundant.

After a some research i found the way to bypass ssl error Trust anchor for certification path not found. This might be not a good way to do but you can use it for a testing purpose.

 private HttpsURLConnection httpsUrlConnection( URL urlDownload) throws Exception {
  HttpsURLConnection connection=null;
        TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {

                return null;
            }

            @SuppressLint("TrustAllX509TrustManager")
            public void checkClientTrusted(X509Certificate[] certs, String authType) {
            }

            @SuppressLint("TrustAllX509TrustManager")
            public void checkServerTrusted(X509Certificate[] certs, String authType) {
            }
        }
        };
        SSLContext sc = SSLContext.getInstance("SSL"); // Add in try catch block if you get error.
        sc.init(null, trustAllCerts, new java.security.SecureRandom()); // Add in try catch block if you get error.
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

        HostnameVerifier usnoHostnameVerifier = new HostnameVerifier() {
            @Override
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        };

        SSLSocketFactory sslSocketFactory = sc.getSocketFactory();

        connection = (HttpsURLConnection) urlDownload.openConnection();
        connection.setHostnameVerifier(usnoHostnameVerifier);
        connection.setSSLSocketFactory(sslSocketFactory);

        return connection;
    }

One of the reasons for this error is the use of the jaxb implementation from the jdk. I am not sure why such a problem can appear in pretty simple xml parsing situations. You may use the latest version of the jaxb library from a public maven repository:

http://mvnrepository.com

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.2.12</version>
</dependency>

I had the same problem. java.net.UnknownHostException: Unable to resolve host “”...

I'm running Visual Studio 2019 and Xamarin.

I also switched back to my WiFi but was on a hot spot.

I solved this by clean swiping the emulator. Restore to factory settings. Then re-running visual studio xamarin app which wil redeploy your app again to the fresh emulator.

It worked. I thought I was going to battle for days to solve this. Luckily this post pointed me in the right direction.

I could not understand how it worked perfectly before and then stopped with no code change.

This is my code for reference:

using var response = await httpClient.GetAsync(sb.ToString());
string apiResponse = await response.Content.ReadAsStringAsync();

Exit code 137 (128+9) indicates that your program exited due to receiving signal 9, which is SIGKILL. This also explains the killed message. The question is, why did you receive that signal?

The most likely reason is probably that your process crossed some limit in the amount of system resources that you are allowed to use. Depending on your OS and configuration, this could mean you had too many open files, used too much filesytem space or something else. The most likely is that your program was using too much memory. Rather than risking things breaking when memory allocations started failing, the system sent a kill signal to the process that was using too much memory.

As I commented earlier, one reason you might hit a memory limit after printing finished counting is that your call to counter.items() in your final loop allocates a list that contains all the keys and values from your dictionary. If your dictionary had a lot of data, this might be a very big list. A possible solution would be to use counter.iteritems() which is a generator. Rather than returning all the items in a list, it lets you iterate over them with much less memory usage.

So, I'd suggest trying this, as your final loop:

for key, value in counter.iteritems():
    writer.writerow([key, value])

Note that in Python 3, items returns a "dictionary view" object which does not have the same overhead as Python 2's version. It replaces iteritems, so if you later upgrade Python versions, you'll end up changing the loop back to the way it was.

ser.read(64) should be ser.read(size=64); ser.read uses keyword arguments, not positional.

Also, you're reading from the port twice; what you probably want to do is this:

i=0
for modem in PortList:

The AlexFTPS library used in the question seems to be dead (was not updated since 2011).

With no external libraries

You can try to implement this without any external library. But unfortunately, neither the .NET Framework nor PowerShell have any explicit support for downloading all files in a directory (let only recursive file downloads).

You have to implement that yourself:

• List the remote directory
• Iterate the entries, downloading files (and optionally recursing into subdirectories - listing them again, etc.)

Tricky part is to identify files from subdirectories. There's no way to do that in a portable way with the .NET framework (FtpWebRequest or WebClient). The .NET framework unfortunately does not support the MLSD command, which is the only portable way to retrieve directory listing with file attributes in FTP protocol. See also Checking if object on FTP server is file or directory.

Your options are:

• If you know that the directory does not contain any subdirectories, use the ListDirectory method (NLST FTP command) and simply download all the "names" as files.
• Do an operation on a file name that is certain to fail for file and succeeds for directories (or vice versa). I.e. you can try to download the "name".
• You may be lucky and in your specific case, you can tell a file from a directory by a file name (i.e. all your files have an extension, while subdirectories do not)
• You use a long directory listing (LIST command = ListDirectoryDetails method) and try to parse a server-specific listing. Many FTP servers use *nix-style listing, where you identify a directory by the d at the very beginning of the entry. But many servers use a different format. The following example uses this approach (assuming the *nix format)

function DownloadFtpDirectory($url, $credentials, $localPath)
{
    $listRequest = [Net.WebRequest]::Create($url)
    $listRequest.Method = [System.Net.WebRequestMethods+Ftp]::ListDirectoryDetails
    $listRequest.Credentials = $credentials

    $lines = New-Object System.Collections.ArrayList

    $listResponse = $listRequest.GetResponse()
    $listStream = $listResponse.GetResponseStream()
    $listReader = New-Object System.IO.StreamReader($listStream)
    while (!$listReader.EndOfStream)
    {
        $line = $listReader.ReadLine()
        $lines.Add($line) | Out-Null
    }
    $listReader.Dispose()
    $listStream.Dispose()
    $listResponse.Dispose()

    foreach ($line in $lines)
    {
        $tokens = $line.Split(" ", 9, [StringSplitOptions]::RemoveEmptyEntries)
        $name = $tokens[8]
        $permissions = $tokens[0]

        $localFilePath = Join-Path $localPath $name
        $fileUrl = ($url + $name)

        if ($permissions[0] -eq 'd')
        {
            if (!(Test-Path $localFilePath -PathType container))
            {
                Write-Host "Creating directory $localFilePath"
                New-Item $localFilePath -Type directory | Out-Null
            }

            DownloadFtpDirectory ($fileUrl + "/") $credentials $localFilePath
        }
        else
        {
            Write-Host "Downloading $fileUrl to $localFilePath"

            $downloadRequest = [Net.WebRequest]::Create($fileUrl)
            $downloadRequest.Method = [System.Net.WebRequestMethods+Ftp]::DownloadFile
            $downloadRequest.Credentials = $credentials

            $downloadResponse = $downloadRequest.GetResponse()
            $sourceStream = $downloadResponse.GetResponseStream()
            $targetStream = [System.IO.File]::Create($localFilePath)
            $buffer = New-Object byte[] 10240
            while (($read = $sourceStream.Read($buffer, 0, $buffer.Length)) -gt 0)
            {
                $targetStream.Write($buffer, 0, $read);
            }
            $targetStream.Dispose()
            $sourceStream.Dispose()
            $downloadResponse.Dispose()
        }
    }
}

Use the function like:

$credentials = New-Object System.Net.NetworkCredential("user", "mypassword") 
$url = "ftp://ftp.example.com/directory/to/download/"
DownloadFtpDirectory $url $credentials "C:\target\directory"

The code is translated from my C# example in C# Download all files and subdirectories through FTP.

Using 3rd party library

If you want to avoid troubles with parsing the server-specific directory listing formats, use a 3rd party library that supports the MLSD command and/or parsing various LIST listing formats. And ideally with a support for downloading all files from a directory or even recursive downloads.

For example with WinSCP .NET assembly you can download whole directory with a single call to Session.GetFiles:

# Load WinSCP .NET assembly
Add-Type -Path "WinSCPnet.dll"

# Setup session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Ftp
    HostName = "ftp.example.com"
    UserName = "user"
    Password = "mypassword"
}

$session = New-Object WinSCP.Session

try
{
    # Connect
    $session.Open($sessionOptions)

    # Download files
    $session.GetFiles("/directory/to/download/*", "C:\target\directory\*").Check()
}
finally
{
    # Disconnect, clean up
    $session.Dispose()
}    

Internally, WinSCP uses the MLSD command, if supported by the server. If not, it uses the LIST command and supports dozens of different listing formats.

The Session.GetFiles method is recursive by default.

(I'm the author of WinSCP)

Get rid of the escape characters before storing or manipulating the raw string:

You could change any backslashes of the path '\' to forward slashes '/' before storing them in a variable. The forward slashes don't need to be escaped:

>>> mypath = os.getcwd().replace('\\','/')  
>>> os.path.exists(mypath)  
True  
>>>   

Yet another trick (as of v1.6)

A=np.arange(1,10).reshape(3,3)
b=np.arange(3)

np.einsum('ij,i->ij',A,b)

I'm proficient with the numpy broadcasting (newaxis), but I'm still finding my way around this new einsum tool. So I had play around a bit to find this solution.

Timings (using Ipython timeit):

einsum: 4.9 micro
transpose: 8.1 micro
newaxis: 8.35 micro
dot-diag: 10.5 micro

Incidentally, changing a i to j, np.einsum('ij,j->ij',A,b), produces the matrix that Alex does not want. And np.einsum('ji,j->ji',A,b) does, in effect, the double transpose.

Also try to dos2unix the shell script, because sometimes it has Windows line endings and the shell does not recognize it.

$ dos2unix MigrateNshell.sh

This helps sometimes.

    .img-wrap:hover img {_x000D_
        transform: scale(0.8);_x000D_
    }_x000D_
    .img-wrap img {_x000D_
        display: block;_x000D_
        transition: all 0.3s ease 0s;_x000D_
        width: 100%;_x000D_
    }

    <div class="img-wrap">_x000D_
    <img src="http://www.sampleimages/images.jpg"/> // Your image_x000D_
    </div>

This code is only for zoom-out effect.Set the div "img-wrap" according to your styles and insert the above style results zoom-out effect.For zoom-in effect you must increase the scale value(eg: for zoom-in,use transform: scale(1.3);

This might not really answer the question, but just in case someone just need to quickly send a string value to a function that require a NSArray parameter.

NSArray *data = @[@"The String Value"];

if you need to send more than just 1 string value, you could also use

NSArray *data = @[@"The String Value", @"Second String", @"Third etc"];

then you can send it to the function like below

theFunction(data);

Open the file by calling open and then using csv.DictReader.

input_file = csv.DictReader(open("coors.csv"))

You may iterate over the rows of the csv file dict reader object by iterating over input_file.

for row in input_file:
    print(row)

OR To access first line only

dictobj = csv.DictReader(open('coors.csv')).next() 

UPDATE In python 3+ versions, this code would change a little:

reader = csv.DictReader(open('coors.csv'))
dictobj = next(reader) 

JAX-RS implementations automatically support marshalling/unmarshalling of classes based on discoverable JAXB annotations, but because your payload is declared as Object, I think the created JAXBContext misses the Department class and when it's time to marshall it it doesn't know how.

A quick and dirty fix would be to add a XmlSeeAlso annotation to your response class:

@XmlRootElement
@XmlSeeAlso({Department.class})
public class Response implements Serializable {
  ....

or something a little more complicated would be "to enrich" the JAXB context for the Response class by using a ContextResolver:

import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;

@Provider
@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
public class ResponseResolver implements ContextResolver<JAXBContext> {
    private JAXBContext ctx;

    public ResponseResolver() {
        try {
            this.ctx = JAXBContext.newInstance(

                        Response.class, 
                        Department.class

                    );
        } catch (JAXBException ex) {
            throw new RuntimeException(ex);
        }
    }

    public JAXBContext getContext(Class<?> type) {
        return (type.equals(Response.class) ? ctx : null);
    }
}

In Mac, for me this works:

CONFIGURE_OPTS="--enable-shared" rbenv install 2.2.2

From a Java Game Engine:

/**
 * Converts a given Image into a BufferedImage
 *
 * @param img The Image to be converted
 * @return The converted BufferedImage
 */
public static BufferedImage toBufferedImage(Image img)
{
    if (img instanceof BufferedImage)
    {
        return (BufferedImage) img;
    }

    // Create a buffered image with transparency
    BufferedImage bimage = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_ARGB);

    // Draw the image on to the buffered image
    Graphics2D bGr = bimage.createGraphics();
    bGr.drawImage(img, 0, 0, null);
    bGr.dispose();

    // Return the buffered image
    return bimage;
}

The solution would be to use sessionStorage, FYI: https://developer.mozilla.org/en-US/docs/Web/API/Window/sessionStorage

I have improved @dacoinminster answer and this is the result with an example to share your app:

// Intents with SEND action
PackageManager packageManager = context.getPackageManager();
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
List<ResolveInfo> resolveInfoList = packageManager.queryIntentActivities(sendIntent, 0);

List<LabeledIntent> intentList = new ArrayList<LabeledIntent>();
Resources resources = context.getResources();

for (int j = 0; j < resolveInfoList.size(); j++) {
    ResolveInfo resolveInfo = resolveInfoList.get(j);
    String packageName = resolveInfo.activityInfo.packageName;
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_SEND);
    intent.setComponent(new ComponentName(packageName,
    resolveInfo.activityInfo.name));
    intent.setType("text/plain");

    if (packageName.contains("twitter")) {
        intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.twitter) + "https://play.google.com/store/apps/details?id=" + context.getPackageName());
    } else {
        // skip android mail and gmail to avoid adding to the list twice
        if (packageName.contains("android.email") || packageName.contains("android.gm")) {
            continue;
        }
        intent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.largeTextForFacebookWhatsapp) + "https://play.google.com/store/apps/details?id=" + context.getPackageName());
    }

    intentList.add(new LabeledIntent(intent, packageName, resolveInfo.loadLabel(packageManager), resolveInfo.icon));
}

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:"));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, resources.getString(R.string.subjectForMailApps));
emailIntent.putExtra(Intent.EXTRA_TEXT, resources.getString(R.string.largeTextForMailApps) + "https://play.google.com/store/apps/details?id=" + context.getPackageName());

context.startActivity(Intent.createChooser(emailIntent, resources.getString(R.string.compartirEn)).putExtra(Intent.EXTRA_INITIAL_INTENTS, intentList.toArray(new LabeledIntent[intentList.size()])));

We recently upgraded to the NuGet version of SqlClient (Microsoft.Data.SqlClient) which contains a bug. This bug was introduced during the lifetime of the 1.x cycle and has already been fixed. The fix will be available in the 2.0.0 release which is not available at the time of this writing. A preview is available.

You can inspect the details here: https://github.com/dotnet/SqlClient/issues/262

Or use the menu: Tools->Preferences->Database->NLS and change language and territory.

Not sure whether this answer has already appeared...

For the particular pattern in the question, you can just do it with a single grep() call,

grep("A[169]", myfile$Letter)

If you're getting this error and you are using Maven to build your Jars, then there is a good chance that you simply do not have your Java classes in src/main/java/.

In my case I created my project in Eclipse which defaults to src (rather than src/main/java/.

So I ended up with something like mypackage.morepackage.myclass and a directory structure looking like src/mypackage/morepackage/myclass, which inherently has nothing wrong. But when you run mvn clean install it will look for src/main/java/mypackage/morepackage/myclass. It will not find the class but it won't error either. So it will successfully build and you when you run your outputted Jar the result is:

Error: Could not find or load main class mypackage.morepackage.myclass

Because it simply never included your class in the packaged Jar.

You are trying to execute an asynchronous function in a synchronous way, which is unfortunately not possible in Javascript.

As you guessed correctly, the roomId=results.... is executed when the loading from the DB completes, which is done asynchronously, so AFTER the resto of your code is completed.

Look at this article, it talks about .insert and not .find, but the idea is the same : http://metaduck.com/01-asynchronous-iteration-patterns.html

Lapack is a Linear Algebra package which is used by R (actually it's used everywhere) underneath solve(), dgesv spits this kind of error when the matrix you passed as a parameter is singular.

As an addendum: dgesv performs LU decomposition, which, when using your matrix, forces a division by 0, since this is ill-defined, it throws this error. This only happens when matrix is singular or when it's singular on your machine (due to approximation you can have a really small number be considered 0)

I'd suggest you check its determinant if the matrix you're using contains mostly integers and is not big. If it's big, then take a look at this link.

you can use str_replace say your name is in variable $name

$result = str_replace(' ', '_', $name);

another way is to use regex, as it will help to eliminate 2-time space etc.

  $result=  preg_replace('/\s+/', '_', $name);

You can use http_build_query to generate a URL-encoded querystring from an array in PHP. Whilst the resulting querystring will be expanded, you can decide on a unique separator you want as a parameter to the http_build_query method, so when it comes to decoding, you can check what separator was used. If it was the unique one you chose, then that would be the array querystring otherwise it would be the normal querystrings.

A truly amazing list of answers, but since one pretty good one is still missing, I'll mention it here: open the csv file with google sheets and save it back to your local computer as an excel file.

In contrast to Microsoft, Google has managed to support UTF-8 csv files so it just works to open the file there. And the export to excel format also just works. So even though this may not be the preferred solution for all, it is pretty fail safe and the number of clicks is not as high as it may sound, especially when you're already logged into google anyway.

This approach works for me in SQLite and MySQL. It may work with others, please let me know your experience.

• Works if rows are present
• Works if no rows are present (test with DELETE FROM table)

Code:

$calendarDatabase = new \PDO('sqlite:calendar-of-tasks.db');    
$statement = $calendarDatabase->query('SELECT *, COUNT(*) FROM data LIMIT 1');
$columns = array_keys($statement->fetch(PDO::FETCH_ASSOC));
array_pop($columns);
var_dump($columns);

I make no guarantees that this is valid SQL per ANSI or other, but it works for me.

I had the same issue, my problem was, that I had two different webservices with two different wsdl-files. I generated the sources in the same package for both webservices, which seems to be a problem. I guess it's because of the ObjectFactory and perhaps also because of the package-info.java - because those are only generated once.

I solved it, by generating the sources for each webservice in a different package. This way, you also have two different ObjectFactories and package-info.java files.

As it wasn't mentioned in any answers, just in case you want to align and space your text, you can use the string format features. (above python 2.5) Of course \t is actually a TAB token whereas the described method generates spaces.

Example:

print "{0:30} {1}".format("hi", "yes")
> hi                             yes

Another Example, left aligned:

print("{0:<10} {1:<10} {2:<10}".format(1.0, 2.2, 4.4))
>1.0        2.2        4.4 

Because 1 is numeric, but not integer (i.e. it's a floating point number), and 1:6000 is numeric and integer.

> print(class(1))
[1] "numeric"
> print(class(1:60000))
[1] "integer"

60000 squared is 3.6 billion, which is NOT representable in signed 32-bit integer, hence you get an overflow error:

> as.integer(60000)*as.integer(60000)
[1] NA
Warning message:
In as.integer(60000) * as.integer(60000) : NAs produced by integer overflow

3.6 billion is easily representable in floating point, however:

> as.single(60000)*as.single(60000)
[1] 3.6e+09

To fix your for code, convert to a floating point representation:

function (N)
{
    for(i in as.single(1:N)) {
        y <- i*i
    }
}

Here it is:

select player_name, player_salary, (player_salary * 1.1) as player_newsalary
from player 
order by player_name, player_salary, player_newsalary desc

You don't need to "group by" if there is only one instance of a player in the table.

None of these other answers worked for me. Here's what I had to do to run a procedure in SQL Developer 3.2.20.10:

SET serveroutput on;
DECLARE
  testvar varchar(100);
BEGIN
  testvar := 'dude';
  schema.MY_PROC(testvar);
  dbms_output.enable;
  dbms_output.put_line(testvar);
END;

And then you'd have to go check the table for whatever your proc was supposed to do with that passed-in variable -- the output will just confirm that the variable received the value (and theoretically, passed it to the proc).

NOTE (differences with mine vs. others):

• No : prior to the variable name
• No putting .package. or .packages. between the schema name and the procedure name
• No having to put an & in the variable's value.
• No using print anywhere
• No using var to declare the variable

All of these problems left me scratching my head for the longest and these answers that have these egregious errors out to be taken out and tarred and feathered.

Maybe you have a file/directory named test in the directory. If this directory exists, and has no dependencies that are more recent, then this target is not rebuild.

To force rebuild on these kind of not-file-related targets, you should make them phony as follows:

.PHONY: all test clean

Note that you can declare all of your phony targets there.

A phony target is one that is not really the name of a file; rather it is just a name for a recipe to be executed when you make an explicit request.

I had this issue, and solved. This was due to the WHERE clause contains String value instead of integer value.

Have created a simple dictionary in JS here:

function JSdict() {
    this.Keys = [];
    this.Values = [];
}

// Check if dictionary extensions aren't implemented yet.
// Returns value of a key
if (!JSdict.prototype.getVal) {
    JSdict.prototype.getVal = function (key) {
        if (key == null) {
            return "Key cannot be null";
        }
        for (var i = 0; i < this.Keys.length; i++) {
            if (this.Keys[i] == key) {
                return this.Values[i];
            }
        }
        return "Key not found!";
    }
}


// Check if dictionary extensions aren't implemented yet.
// Updates value of a key
if (!JSdict.prototype.update) {
    JSdict.prototype.update = function (key, val) {
        if (key == null || val == null) {
            return "Key or Value cannot be null";
        }
        // Verify dict integrity before each operation
        if (keysLength != valsLength) {
            return "Dictionary inconsistent. Keys length don't match values!";
        }
        var keysLength = this.Keys.length;
        var valsLength = this.Values.length;
        var flag = false;
        for (var i = 0; i < keysLength; i++) {
            if (this.Keys[i] == key) {
                this.Values[i] = val;
                flag = true;
                break;
            }
        }
        if (!flag) {
            return "Key does not exist";
        }
    }
}



// Check if dictionary extensions aren't implemented yet.
// Adds a unique key value pair
if (!JSdict.prototype.add) {
    JSdict.prototype.add = function (key, val) {
        // Allow only strings or numbers as keys
        if (typeof (key) == "number" || typeof (key) == "string") {
            if (key == null || val == null) {
                return "Key or Value cannot be null";
            }
            if (keysLength != valsLength) {
                return "Dictionary inconsistent. Keys length don't match values!";
            }
            var keysLength = this.Keys.length;
            var valsLength = this.Values.length;
            for (var i = 0; i < keysLength; i++) {
                if (this.Keys[i] == key) {
                    return "Duplicate keys not allowed!";
                }
            }
            this.Keys.push(key);
            this.Values.push(val);
        }
        else {
            return "Only number or string can be key!";
        }
    }
}

// Check if dictionary extensions aren't implemented yet.
// Removes a key value pair
if (!JSdict.prototype.remove) {
    JSdict.prototype.remove = function (key) {
        if (key == null) {
            return "Key cannot be null";
        }
        if (keysLength != valsLength) {
            return "Dictionary inconsistent. Keys length don't match values!";
        }
        var keysLength = this.Keys.length;
        var valsLength = this.Values.length;
        var flag = false;
        for (var i = 0; i < keysLength; i++) {
            if (this.Keys[i] == key) {
                this.Keys.shift(key);
                this.Values.shift(this.Values[i]);
                flag = true;
                break;
            }
        }
        if (!flag) {
            return "Key does not exist";
        }
    }
}

The above implementation can now be used to simulate a dictionary as:

var dict = new JSdict();

dict.add(1, "one")

dict.add(1, "one more")
"Duplicate keys not allowed!"

dict.getVal(1)
"one"

dict.update(1, "onne")

dict.getVal(1)
"onne"

dict.remove(1)

dict.getVal(1)
"Key not found!"

This is just a basic simulation. It can be further optimized by implementing a better running time algorithm to work in atleast O(nlogn) time complexity or even less. Like merge/quick sort on arrays and then some B-search for lookups. I Didn't give a try or searched about mapping a hash function in JS.

Also, Key and Value for the JSdict obj can be turned into private variables to be sneaky.

Hope this helps!

EDIT >> After implementing the above, I personally used the JS objects as associative arrays that are available out-of-the-box.

However, I would like to make a special mention about two methods that actually proved helpful to make it a convenient hashtable experience.

Viz: dict.hasOwnProperty(key) and delete dict[key]

Read this post as a good resource on this implementation/usage. Dynamically creating keys in JavaScript associative array

THanks!

Here is my solution, which I think is a bit less hackish than most others here. It is similar to nightowl's answer.

someclasses = [MyClass(), MyClass(), MyClass()]

def method_caller(some_object, some_method='the method'):
    return getattr(some_object, some_method)()

othermethod = partial(method_caller, some_method='othermethod')

with Pool(6) as pool:
    result = pool.map(othermethod, someclasses)

For simple stuff, System.currentTimeMillis() can work.

It's actually so common that my IDE is setup so that upon entering "t0" it generates me the following line:

final long t0 = System.currentTimeMillis()

But for more complicated things, you'll probably want to use statistical time measurements, like here (scroll down a bit and look at the time measurements expressed including standard deviations etc.):

http://perf4j.codehaus.org/devguide.html

$k=preg_replace('/\s+/', '',$k); 

did it for me. And yes, testing on Chrome. Thx to user2254008

for your example:

{'profiles': [{'name':'john', 'age': 44}, {'name':'Alex','age':11}]}

you will have to do something of this effect:

JSONObject myjson = new JSONObject(the_json);
JSONArray the_json_array = myjson.getJSONArray("profiles");

this returns the array object.

Then iterating will be as follows:

    int size = the_json_array.length();
    ArrayList<JSONObject> arrays = new ArrayList<JSONObject>();
    for (int i = 0; i < size; i++) {
        JSONObject another_json_object = the_json_array.getJSONObject(i);
            //Blah blah blah...
            arrays.add(another_json_object);
    }

//Finally
JSONObject[] jsons = new JSONObject[arrays.size()];
arrays.toArray(jsons);

//The end...

You will have to determine if the data is an array (simply checking that charAt(0) starts with [ character).

Hope this helps.

This will get you close, the add button has been removed out of the table so you might want to consider this...

<script type="text/javascript">
    $(document).ready(function() {
        $("#add").click(function() {
          $('#mytable tbody>tr:last').clone(true).insertAfter('#mytable tbody>tr:last');
          return false;
        });
    });
</script>

HTML markup looks like this

  <a  id="add">+</a></td>
  <table id="mytable" width="300" border="1" cellspacing="0" cellpadding="2">
  <tbody>
    <tr>
      <td>Name</td>
    </tr>
    <tr class="person">
      <td><input type="text" name="name" id="name" /></td>
    </tr>
    </tbody>
  </table>

EDIT To empty a value of a textbox after insert..

    $('#mytable tbody>tr:last').clone(true).insertAfter('#mytable tbody>tr:last');
    $('#mytable tbody>tr:last #name').val('');
    return false;

EDIT2 Couldn't help myself, to reset all dropdown lists in the inserted TR you can do this

$("#mytable tbody>tr:last").each(function() {this.reset();});           

I will leave the rest to you!

The simplest and best solution is just to use XMLRoot attribute in your class, in which you wish to deserialize.

Like:

[XmlRoot(ElementName = "YourPreferableNameHere")]
public class MyClass{
...
}

Also, use the following Assembly :

using System.Xml.Serialization;

You probably want os.makedirs as it will create intermediate directories as well, if needed.

import os

#dir is not keyword
def makemydir(whatever):
  try:
    os.makedirs(whatever)
  except OSError:
    pass
  # let exception propagate if we just can't
  # cd into the specified directory
  os.chdir(whatever)

Like you said in your title, fgetcsv is the way to go. It's pretty darn easy to use.

$file = fopen('myCSVFile.csv', 'r');
while (($line = fgetcsv($file)) !== FALSE) {
  //$line is an array of the csv elements
  print_r($line);
}
fclose($file);

You'll want to put more error checking in there in case fopen() fails, but this works to read a CSV file line by line and parse the line into an array.

If you are getting that error , then I can say that your application doesn't have a write permission on some directory.

For example, if you are trying to save the Image from the memory stream to the file system , you may get that error.

Please if you are using XP, make sure to add write permission for the aspnet account on that folder.

If you are using windows server (2003,2008) or Vista, make sure that add write permission for the Network service account.

Hope it help some one.

Previous answers point out correctly that you can only do this with the standard JDK tools by converting the JKS file into PKCS #12 format first. If you're interested, I put together a compact utility to import OpenSSL-derived keys into a JKS-formatted keystore without having to convert the keystore to PKCS #12 first: http://commandlinefanatic.com/cgi-bin/showarticle.cgi?article=art049

You would use the linked utility like this:

$ openssl req -x509 -newkey rsa:2048 -keyout localhost.key -out localhost.csr -subj "/CN=localhost"

(sign the CSR, get back localhost.cer)

$ openssl rsa -in localhost.key -out localhost.rsa
Enter pass phrase for localhost.key:
writing RSA key
$ java -classpath . KeyImport -keyFile localhost.rsa -alias localhost -certificateFile localhost.cer -keystore localhost.jks -keystorePassword changeit -keystoreType JKS -keyPassword changeit

JAXBElement wrappers works for cases where no @XmlRootElement is generated by JAXB. These wrappers are available in ObjectFactory class generated by maven-jaxb2-plugin. For eg:

     public class HelloWorldEndpoint {
        @PayloadRoot(namespace = NAMESPACE_URI, localPart = "person")
        @ResponsePayload
        public JAXBElement<Greeting> sayHello(@RequestPayload JAXBElement<Person> request) {

        Person person = request.getValue();

        String greeting = "Hello " + person.getFirstName() + " " + person.getLastName() + "!";

        Greeting greet = new Greeting();
        greet.setGreeting(greeting);

        ObjectFactory factory = new ObjectFactory();
        JAXBElement<Greeting> response = factory.createGreeting(greet);
        return response;
      }
 }

Did you try refreshing (right click -> refresh) the project folder after copying the file in there? That will SYNC your file system with Eclipse's internal file system.

When you run Eclipse projects, the CWD (current working directory) is project's root directory. Not bin's directory. Not src's directory, but the root dir.

Also, if you're in Linux, remember that its file systems are usually case sensitive.

Unless there is a strong advantage to running your user form in Excel then I would go with a 100% Access solution that would export the reports and data to Excel on an ad-hoc basis.

From what you describe, Access seems the stronger contender as it is built for working with data:
you would have a lot more tools at your disposal to solve any data problems than have to go around the limitations of Excel and shoehorn it into becoming Access...

As for your questions:

1. Very easy. There have been some other questions on SO on that subject.
   See for instance this one and that one.

2. Don't know, but I would guess that there could be a small penalty.
   The biggest difficulty I see is trying to get all the functionalities that Access gives you and re-creating some of these in Excel.

3. Yes, you can have multiple Excel users and a single Access database.
   Here again, using Access as a front-end and keeping the data in a linked Access database on your network would make more sense and it's easy as pie, there's even a wizard in Access to help you do that: it's just 1 click away.

Really, as most other people have said, take a tiny bit of time to get acquainted with Access, it will save you a lot of time and trouble.
You may know Excel better but if you've gone 80% of the way already if you know VBA and are familiar with the Office object model.

Other advantages of doing it in Access: the Access 2007 runtime is free, meaning that if you were to deploy to app to 1 or 30 PC it would cost you the same: nothing.
You only need one full version of Access for your development work (the Runtime doesn't have the designers).

It's a long way around, but System.Uri class has a method named MakeRelativeUri. Maybe you could use that. It's a shame really that System.IO.Path doesn't have this.

Just add attribute runAllManagedModulesForAllRequests="true" to system.webServer\modules in web.config.

This attribute is enabled by default in MVC and Dynamic Data projects.

A far more clear solution is to use the command netsh to change the IP (or setting it back to DHCP)

netsh interface ip set address "Local Area Connection" static 192.168.0.10 255.255.255.0

Where "Local Area Connection" is the name of the network adapter. You could find it in the windows Network Connections, sometimes it is simply named "Ethernet".

Here are two methods to set the IP and also to set the IP back to DHCP "Obtain an IP address automatically"

public bool SetIP(string networkInterfaceName, string ipAddress, string subnetMask, string gateway = null)
{
    var networkInterface = NetworkInterface.GetAllNetworkInterfaces().FirstOrDefault(nw => nw.Name == networkInterfaceName);
    var ipProperties = networkInterface.GetIPProperties();
    var ipInfo = ipProperties.UnicastAddresses.FirstOrDefault(ip => ip.Address.AddressFamily == AddressFamily.InterNetwork);
    var currentIPaddress = ipInfo.Address.ToString();
    var currentSubnetMask = ipInfo.IPv4Mask.ToString();
    var isDHCPenabled = ipProperties.GetIPv4Properties().IsDhcpEnabled;

    if (!isDHCPenabled && currentIPaddress == ipAddress && currentSubnetMask == subnetMask)
        return true;    // no change necessary

    var process = new Process
    {
        StartInfo = new ProcessStartInfo("netsh", $"interface ip set address \"{networkInterfaceName}\" static {ipAddress} {subnetMask}" + (string.IsNullOrWhiteSpace(gateway) ? "" : $"{gateway} 1")) { Verb = "runas" }
    };
    process.Start();
    var successful = process.ExitCode == 0;
    process.Dispose();
    return successful;
}

public bool SetDHCP(string networkInterfaceName)
{
    var networkInterface = NetworkInterface.GetAllNetworkInterfaces().FirstOrDefault(nw => nw.Name == networkInterfaceName);
    var ipProperties = networkInterface.GetIPProperties();
    var isDHCPenabled = ipProperties.GetIPv4Properties().IsDhcpEnabled;

    if (isDHCPenabled)
        return true;    // no change necessary

    var process = new Process
    {
        StartInfo = new ProcessStartInfo("netsh", $"interface ip set address \"{networkInterfaceName}\" dhcp") { Verb = "runas" }
    };
    process.Start();
    var successful = process.ExitCode == 0;
    process.Dispose();
    return successful;
}

I had issues along the same lines you do. In order to test the software behavior, I just unplugged the network cable at the appropriate time. I had to set a break-point right before I wanted to unplug the cable.

If I were doing it again, I'd put a switch (a normally closed momentary push button one) in a network cable.

If the physical disconnect causes a different behavior, you could connect your computer to a cheap hub and put the switch I mentioned above between your hub and the main network.

-- EDIT -- In many cases you'll need the network connection working until you get to a certain point in your program, THEN you'll want to disconnect using one of the many suggestions offered.

It's not actually a C# hidden feature, but I recently discovered the WeakReference class and was blown away by it (although this may be biased by the fact that it helped me found a solution to a particular problem of mine...)

Quote from xlsxwriter module documentation:

This module cannot be used to modify or write to an existing Excel XLSX file.

If you want to modify existing xlsx workbook, consider using openpyxl module.

See also:

• Modify an existing Excel file using Openpyxl in Python
• Use openpyxl to edit a Excel2007 file (.xlsx) without changing its own styles?

Here are the steps that happen internally for both calls:
(Hint: the only difference is in step 3)

new Test():

1. create new Object() obj
2. set obj.__proto__ to Test.prototype
3. return Test.call(obj) || obj; // normally obj is returned but constructors in JS can return a value

Object.create( Test.prototype )

1. create new Object() obj
2. set obj.__proto__ to Test.prototype
3. return obj;

So basically Object.create doesn't execute the constructor.

cellspacing (distance between cells) parameter of the TABLE tag is precisely what you want. The disadvantage is it's one value, used both for x and y, you can't choose different spacing or padding vertically/horizontally. There is a CSS property too, but it's not widely supported.

in C#:

new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1).AddMonths(-1)
new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1).AddDays(-1)

The resource I always end up going back to about HTML emails is CampaignMonitor's CSS guide.

As their business is geared solely around email delivery, they know their stuff as well as anyone is going to

Normally, all lists are being displayed vertically anyways. So do you want to display it horizontally?

Anyways, you asked to override the main css file and set some css locally. You cannot do it inside <ul> with style="", that it would apply on the children (<li>).

Closest thing to locally manipulating your list would be:

<style>

For jQuery versions lower than 1.9 (see https://api.jquery.com/toggle-event):

$('#user_button').toggle(function () {
    $("#user_button").css({borderBottomLeftRadius: "0px"});
}, function () {
    $("#user_button").css({borderBottomLeftRadius: "5px"});
});

Using classes in this case would be better than setting the css directly though, look at the addClass and removeClass methods alecwh mentioned.

$('#user_button').toggle(function () {
    $("#user_button").addClass("active");
}, function () {
    $("#user_button").removeClass("active");
});

I would try formatting your table correctly first off like so:

I cannot help but thinking that formatting the table could at the very least not do any harm.

<table>
   <thead>
      <th>Header1</th>
      ......
   </thead>
   <tbody>
       <tr><td>Content1</td>....</tr>
       ......
   </tbody>
</table>

What happens, if you do this way:-

$('#new_user_form input, #new_user_form select').each(function(key, value) {

Refer LIVE DEMO

The way you import a .cer file into the trust store is the same way you'd import a .crt file from say an export from Firefox.

You do not have to put an alias and the password of the keystore, you can just type:

keytool -v -import -file somefile.crt  -alias somecrt -keystore my-cacerts

Preferably use the cacerts file that is already in your Java installation (jre\lib\security\cacerts) as it contains secure "popular" certificates.

Update regarding the differences of cer and crt (just to clarify) According to Apache with SSL - How to convert CER to CRT certificates? and user @Spawnrider

CER is a X.509 certificate in binary form, DER encoded.
CRT is a binary X.509 certificate, encapsulated in text (base-64) encoding.
It is not the same encoding.

I"m guessing i'm getting this error because the string is trying to substring a Null value. But wouldn't the ".length() > 0" part eliminate that issue?

No, calling itemdescription.length() when itemdescription is null would not generate a StringIndexOutOfBoundsException, but rather a NullPointerException since you would essentially be trying to call a method on null.

As others have indicated, StringIndexOutOfBoundsException indicates that itemdescription is not at least 38 characters long. You probably want to handle both conditions (I assuming you want to truncate):

final String value;
if (itemdescription == null || itemdescription.length() <= 0) {
    value = "_";
} else if (itemdescription.length() <= 38) {
    value = itemdescription;
} else { 
    value = itemdescription.substring(0, 38);
}
pstmt2.setString(3, value);

Might be a good place for a utility function if you do that a lot...

Not an answer as much as examples...

Example #1:

<div style="width:45px; height:45px; border: solid thin red; overflow: visible">
    Hello&nbsp;There
</div>  

Example #2:

<div style="width:45px; height:45px; border: solid thin red; overflow: visible">
    Hello There
</div>

And link to the fiddle.

Your example shows an Object, not an Array. In that case, the preferred way to add a field to an Object is to just assign to it, like so:

arr.key3 = value3;

Prior to Java 8

We could have used Arrays.toString(array) to print one dimensional array and Arrays.deepToString(array) for multi-dimensional arrays.

Java 8

Now we have got the option of Stream and lambda to print the array.

Printing One dimensional Array:

public static void main(String[] args) {
    int[] intArray = new int[] {1, 2, 3, 4, 5};
    String[] strArray = new String[] {"John", "Mary", "Bob"};

    //Prior to Java 8
    System.out.println(Arrays.toString(intArray));
    System.out.println(Arrays.toString(strArray));

    // In Java 8 we have lambda expressions
    Arrays.stream(intArray).forEach(System.out::println);
    Arrays.stream(strArray).forEach(System.out::println);
}

The output is:

[1, 2, 3, 4, 5]
[John, Mary, Bob]
1
2
3
4
5
John
Mary
Bob

Printing Multi-dimensional Array Just in case we want to print multi-dimensional array we can use Arrays.deepToString(array) as:

public static void main(String[] args) {
    int[][] int2DArray = new int[][] { {11, 12}, { 21, 22}, {31, 32, 33} };
    String[][] str2DArray = new String[][]{ {"John", "Bravo"} , {"Mary", "Lee"}, {"Bob", "Johnson"} };

    //Prior to Java 8
    System.out.println(Arrays.deepToString(int2DArray));
    System.out.println(Arrays.deepToString(str2DArray));

    // In Java 8 we have lambda expressions
    Arrays.stream(int2DArray).flatMapToInt(x -> Arrays.stream(x)).forEach(System.out::println);
    Arrays.stream(str2DArray).flatMap(x -> Arrays.stream(x)).forEach(System.out::println);
} 

Now the point to observe is that the method Arrays.stream(T[]), which in case of int[] returns us Stream<int[]> and then method flatMapToInt() maps each element of stream with the contents of a mapped stream produced by applying the provided mapping function to each element.

The output is:

[[11, 12], [21, 22], [31, 32, 33]]
[[John, Bravo], [Mary, Lee], [Bob, Johnson]]
11
12
21
22
31
32
33
John
Bravo
Mary
Lee
Bob
Johnson

In this case, it doesn't matter as there is no content between the two divs.

Either one will get the browser to scroll down to it.

The a element will look like:

<a href="mypageName.html#buttonOne">buttonOne</a>

Or:

<a href="mypageName.html#linkedinB">linkedinB</a>

If you want to escape from Form Freeze and use editing (like text for a button) use this code

Form form = new Form();
Form.Button.Text = "randomText";
System.Windows.Forms.Application.EnableVisualStyles();
System.Windows.Forms.Application.Run(form);

Why would you want to do this?

IMHO you should store the date as default type and if needed fetch it transforming to desired format.

You could get away with specifying column's format but with a view. I don't know other methods.

Edited:

Seriously, in my opinion, you should create a view on that a table with date type. I'm talking about something like this:

create table sample_table ( id serial primary key, timestamp date); 

and than

create view v_example_table as select id, to_char(date, 'yyyymmmm');

And use v_example_table in your application.

Laravel has inbuilt support for multiple database systems, you need to provide connection details in config/database.php file

return [
    'default' => env('DB_CONNECTION', 'mysql'),

    'connections' => [
        'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'charset' => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix' => '',
            'strict' => false,
            'engine' => null,
        ],
'mysqlOne' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST_ONE', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE_ONE', 'forge'),
            'username' => env('DB_USERNAME_ONE', 'forge'),
            'password' => env('DB_PASSWORD_ONE', ''),
            'charset' => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix' => '',
            'strict' => false,
            'engine' => null,
        ],
];

Once you have this you can create two base model class for each connection and define the connection name in those models

//BaseModel.php
protected $connection = 'mysql';

//BaseModelOne.php
protected $connection = 'mysqlOne';

You can extend these models to create more models for tables in each DB.

Most people choose to use EBS backed instance as it is stateful. It is to safer because everything you have running and installed inside it, will survive stop/stop or any instance failure.

Instance store is stateless, you loose it with all the data inside in case of any instance failure situation. However, it is free and faster because the instance volume is tied to the physical server where the VM is running.

select *  from ##temp1  

This is from MSDN sample:

(*.bmp, *.jpg)|*.bmp;*.jpg

So for your case

openFileDialog1.Filter = "JPG (*.jpg,*.jpeg)|*.jpg;*.jpeg|TIFF (*.tif,*.tiff)|*.tif;*.tiff"

I'll suggest that you use this as it will check for both single and multiple occurrence of white space (as suggested by Lucas Green).

$journalName = preg_replace('/\s+/', '_', $journalName);

instead of:

$journalName = str_replace(' ', '_', $journalName);

I got the same error, when I was trying to import matplotlib.pyplot

In [1]: import matplotlib.pyplot as plt
...
...
ImportError: No module named PyQt4.QtCore

But in my case the problem was due to a missing linux library libGL.so.1

OS : Cent OS 64 bit

Python version : 3.5.2

$> locate libGL.so.1

If this command returns a value, your problem could be different, so please ignore my answer. If it does not return any value and your environment is same as mine, below steps would fix your problem.

$> yum install mesa-libGL.x86_64

This installs the necessary OpenGL libraries for 64 bit Cent OS.

$> locate libGL.so.1
/usr/lib/libGL.so.1

Now go back to iPython and try to import

In [1]: import matplotlib.pyplot as plt

This time it imported successfully.

I'm a bit late to the party, but...

It's worth mentioning that continue is useful for empty loops where all of the work is done in the conditional expression controlling the loop. For example:

while ((buffer[i++] = readChar()) >= 0)
    continue;

In this case, all of the work of reading a character and appending it to buffer is done in the expression controlling the while loop. The continue statement serves as a visual indicator that the loop does not need a body.

It's a little more obvious than the equivalent:

while (...)
{ }

and definitely better (and safer) coding style than using an empty statement like:

while (...)
    ;

Largest negative (32bit) value : -2147483648
(1 << 31)

Largest positive (32bit) value : 2147483647
~(1 << 31)

Mnemonic: "drunk AKA horny"

drunk ========= Drinking age is 21
AK ============ AK 47
A ============= 4 (A and 4 look the same)
horny ========= internet rule 34 (if it exists, there's 18+ material of it) 

21 47 4(years) 3(years) 4(years)
21 47 48       36       48

So you can do this

$('#textarea').attr('enable',false)

try it and give feedback

What's this "other information"? An IP address?

In PHP, you use $_SERVER['REMOTE_ADDR'] to get the IP address of the remote client, then you can use gethostbyaddr() to try and conver that IP into a hostname - but not all IPs have a reverse mapping configured.

Subscript out of Range error occurs when you try to reference an Index for a collection that is invalid.

Most likely, the index in Windows does not actually include .xls. The index for the window should be the same as the name of the workbook displayed in the title bar of Excel.

As a guess, I would try using this:

Windows("Data Sheet - " & ComboBox_Month.Value & " " & TextBox_Year.Value).Activate

ROUND(time_to_sec((TIMEDIFF(NOW(), "2015-06-10 20:15:00"))) / 60);

Found this works for me:

In the link:

<button type="button" class="btn btn-success" data-toggle="modal" data-target="#message<?php echo $row['id'];?>">Message</button>

In the modal:

<div id="message<?php echo $row['id'];?>" class="modal fade" role="dialog">
  <div class="modal-dialog">

    <!-- Modal content-->
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal">&times;</button>
        <h4 class="modal-title">Modal Header</h4>
      </div>
      <div class="modal-body">
        <p>Some text in the modal.</p>
        <?php echo $row['id'];?>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>

  </div>
</div>

Note the guidelines for performing work on a UI thread, collected on my blog:

• Don't block the UI thread for more than 50ms at a time.
• You can schedule ~100 continuations on the UI thread per second; 1000 is too much.

There are two techniques you should use:

1) Use ConfigureAwait(false) when you can.

E.g., await MyAsync().ConfigureAwait(false); instead of await MyAsync();.

ConfigureAwait(false) tells the await that you do not need to resume on the current context (in this case, "on the current context" means "on the UI thread"). However, for the rest of that async method (after the ConfigureAwait), you cannot do anything that assumes you're in the current context (e.g., update UI elements).

For more information, see my MSDN article Best Practices in Asynchronous Programming.

2) Use Task.Run to call CPU-bound methods.

You should use Task.Run, but not within any code you want to be reusable (i.e., library code). So you use Task.Run to call the method, not as part of the implementation of the method.

So purely CPU-bound work would look like this:

// Documentation: This method is CPU-bound.
void DoWork();

Which you would call using Task.Run:

await Task.Run(() => DoWork());

Methods that are a mixture of CPU-bound and I/O-bound should have an Async signature with documentation pointing out their CPU-bound nature:

// Documentation: This method is CPU-bound.
Task DoWorkAsync();

Which you would also call using Task.Run (since it is partially CPU-bound):

await Task.Run(() => DoWorkAsync());

1.Close your project:Completely quit Xcode. 2.Go to your project location:there you will find two files in you root folder with varying extensions: Appname.xcodeproj and Appname.xcworkspace

Now open your project by Double clicking on file with the extensions xcworkspace.(***Appname.xcworkspace*)**

Yourproject will open in xcode. Now run your project again.

If you pay close attention when installing your pods,firebase makes it clear to open your project with your-project.xcworkspace after installing pods firebaseIOS Setup

 $ cd your-project directory
 $ pod init

Add to Podfile

pod 'Firebase/Core'

And finally:

    $ pod install
    $ open your-project.xcworkspace

Dont forget to add firebase to your AppDelegate

Add play-services-safetynet library in android build.gradle:

implementation 'com.google.android.gms:play-services-safetynet:+'

and add this code to your MainApplication.java:

@Override
  public void onCreate() {
    super.onCreate();
    upgradeSecurityProvider();
    SoLoader.init(this, /* native exopackage */ false);
  }

  private void upgradeSecurityProvider() {
    ProviderInstaller.installIfNeededAsync(this, new ProviderInstallListener() {
      @Override
      public void onProviderInstalled() {

      }

      @Override
      public void onProviderInstallFailed(int errorCode, Intent recoveryIntent) {
//        GooglePlayServicesUtil.showErrorNotification(errorCode, MainApplication.this);
        GoogleApiAvailability.getInstance().showErrorNotification(MainApplication.this, errorCode);
      }
    });
  }

Keep in mind that SQL strings can not be larger than 4000 bytes, while Pl/SQL can have strings as large as 32767 bytes. see below for an example of inserting a large string via an anonymous block which I believe will do everything you need it to do.

note I changed the varchar2(32000) to CLOB

set serveroutput ON 
CREATE TABLE testclob 
  ( 
     id NUMBER, 
     c  CLOB, 
     d  VARCHAR2(4000) 
  ); 

DECLARE 
    reallybigtextstring CLOB := '123'; 
    i                   INT; 
BEGIN 
    WHILE Length(reallybigtextstring) <= 60000 LOOP 
        reallybigtextstring := reallybigtextstring 
                               || '000000000000000000000000000000000'; 
    END LOOP; 

    INSERT INTO testclob 
                (id, 
                 c, 
                 d) 
    VALUES     (0, 
                reallybigtextstring, 
                'done'); 

    dbms_output.Put_line('I have finished inputting your clob: ' 
                         || Length(reallybigtextstring)); 
END; 

/ 
SELECT * 
FROM   testclob; 


 "I have finished inputting your clob: 60030"

When using NOT IN, you should also consider NOT EXISTS, which handles the null cases silently. See also PostgreSQL Wiki

SELECT mac, creation_date 
FROM logs lo
WHERE logs_type_id=11
AND NOT EXISTS (
  SELECT *
  FROM consols nx
  WHERE nx.mac = lo.mac
  );

You can simply do a replace in your string like

Str.Replace(@"\\",@"\");

A quicker workaround is to use .asfreq(). This doesn't require creation of a new index to call within .reindex().

# "broken" (staggered) dates
dates = pd.Index([pd.Timestamp('2012-05-01'), 
                  pd.Timestamp('2012-05-04'), 
                  pd.Timestamp('2012-05-06')])
s = pd.Series([1, 2, 3], dates)

print(s.asfreq('D'))
2012-05-01    1.0
2012-05-02    NaN
2012-05-03    NaN
2012-05-04    2.0
2012-05-05    NaN
2012-05-06    3.0
Freq: D, dtype: float64

No difference here, but it matters when you have a type that has a constructor.

struct S {
    constexpr S(int);
};

const S s0(0);
constexpr S s1(1);

s0 is a constant, but it does not promise to be initialized at compile-time. s1 is marked constexpr, so it is a constant and, because S's constructor is also marked constexpr, it will be initialized at compile-time.

Mostly this matters when initialization at runtime would be time-consuming and you want to push that work off onto the compiler, where it's also time-consuming, but doesn't slow down execution time of the compiled program

You could use a regular expression such as the following:

/([-a-z0-9]+)\s*\((.*?)\)\s*(\*)?/

So for example:

$s = "abc-456-hu5t10 (High priority) *";
$s =~ /([-a-z0-9]+)\s*\((.*?)\)\s*(\*)?/;
print "$1\n$2\n$3\n";

prints

abc-456-hu5t10
High priority
*

None of the answers worked for me. If you are running on Ubuntu, you can try:

With python3:

sudo apt-get install python3 python-dev python3-dev \
     build-essential libssl-dev libffi-dev \
     libxml2-dev libxslt1-dev zlib1g-dev \
     python-pip

With Python 2:

sudo apt-get install python-dev  \
     build-essential libssl-dev libffi-dev \
     libxml2-dev libxslt1-dev zlib1g-dev \
     python-pip

Spring has an util class for that:

import org.springframework.util.FileCopyUtils;

InputStream is = connection.getInputStream();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
FileCopyUtils.copy(is, bos);
String data = new String(bos.toByteArray());

Can be achieved also with scriptrunner

ScriptRunner.exe -appvscript demoA.cmd arg1 arg2 -appvscriptrunnerparameters -wait -timeout=30 -rollbackonerror -appvscript demoB.ps1 arg3 arg4 -appvscriptrunnerparameters -wait -timeout=30 

Which also have some features as rollback , timeout and waiting.

This article shows how to do it real easy.

1. To rename a local Git branch, we can use the Git branch -m command to modify the name:

    git branch -m feature1 feature2
   

2. If you’re just looking for the command to rename a remote Git branch, this is it:

    git push -u origin feature2:feature3
   

   Check that you have no tags on the branch before you do this. You can do that with git tag.

First, as a one-time data-scrubbing exercise, delete the orphaned rows e.g.

DELETE 
  FROM ReferencingTable 
 WHERE NOT EXISTS (
                   SELECT * 
                     FROM MainTable AS T1
                    WHERE T1.pk_col_1 = ReferencingTable.pk_col_1
                  );

Second, as a one-time schema-alteration exercise, add the ON DELETE CASCADE referential action to the foreign key on the referencing table e.g.

ALTER TABLE ReferencingTable DROP 
   CONSTRAINT fk__ReferencingTable__MainTable;

ALTER TABLE ReferencingTable ADD 
   CONSTRAINT fk__ReferencingTable__MainTable 
      FOREIGN KEY (pk_col_1)
      REFERENCES MainTable (pk_col_1)
      ON DELETE CASCADE;

Then, forevermore, rows in the referencing tables will automatically be deleted when their referenced row is deleted.

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.

This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.

Whereas a GridLayout is a layout that places its children in a rectangular grid.

It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.

Use <include /> tag.

          <include 
            android:id="@+id/some_id_if_needed"
            layout="@layout/some_layout"/>

Also, read Creating Reusable UI Components and Merging Layouts articles.

Please try to add this into inside the table tag.

border="0" cellspacing="0" cellpadding="0"

<table  border="0" cellspacing="0" cellpadding="0">
...
</table>

I know this question is a couple years old, but I am surprised to find that no one suggested:

   text-align: center;

this is a more universal property than justify-content, and is definitely not unique to grid, but I find that when dealing with text, which is what this question specifically asks about, that it aligns text to the center with-out affecting the space between grid items, or the vertical centering. It centers text horizontally where its stands on its vertical axis. I also find it to remove a layer of complexity that justify-content and align-items adds. justify-content and align-items affects the entire grid item or items, text-align centers the text without affecting the container it is in. Hope this helps.

There's no mention of numpy in the question. If by array you mean list, then if you treat a list as a boolean it will yield True if it has items and False if it's empty.

l = []

if l:
    print "list has items"

if not l:
    print "list is empty"

If you want to be a bit more strict

For ubuntu users, this error may arise because setuptool is not installed system-wide. Simply install setuptool using the command:

sudo apt-get install -y python-setuptools

For python3:

sudo apt-get install -y python3-setuptools

After that, install your package again normally, using

sudo python setup.py install

That's all.

Knowing not to use, and WHY not to use:

SELECT *

For a production system, you can use this configuration :

--ACCESS DB
REVOKE CONNECT ON DATABASE nova FROM PUBLIC;
GRANT  CONNECT ON DATABASE nova  TO user;

--ACCESS SCHEMA
REVOKE ALL     ON SCHEMA public FROM PUBLIC;
GRANT  USAGE   ON SCHEMA public  TO user;

--ACCESS TABLES
REVOKE ALL ON ALL TABLES IN SCHEMA public FROM PUBLIC ;
GRANT SELECT                         ON ALL TABLES IN SCHEMA public TO read_only ;

Very likely your filesystem is out of sync with your Eclipse... Resource is out of sync with the file system. Using SVN? If you "Refresh" all of your projects in explorer, speed returns to normal.

I think it is telling you exactly what is wrong. You cannot compare an integer with a varchar. PostgreSQL is strict and does not do any magic typecasting for you. I'm guessing SQLServer does typecasting automagically (which is a bad thing).

If you want to compare these two different beasts, you will have to cast one to the other using the casting syntax ::.

Something along these lines:

create view view1
as 
select table1.col1,table2.col1,table3.col3
from table1 
inner join
table2 
inner join 
table3
on 
table1.col4::varchar = table2.col5
/* Here col4 of table1 is of "integer" type and col5 of table2 is of type "varchar" */
/* ERROR: operator does not exist: integer = character varying */
....;

Notice the varchar typecasting on the table1.col4.

Also note that typecasting might possibly render your index on that column unusable and has a performance penalty, which is pretty bad. An even better solution would be to see if you can permanently change one of the two column types to match the other one. Literately change your database design.

Or you could create a index on the casted values by using a custom, immutable function which casts the values on the column. But this too may prove suboptimal (but better than live casting).

Don't confuse thread safety with determinism. Thread-safe code can also be non-deterministic. Given the difficulty of debugging problems with threaded code, this is probably the normal case. :-)

Thread safety simply ensures that when a thread is modifying or reading shared data, no other thread can access it in a way that changes the data. If your code depends on a certain order for execution for correctness, then you need other synchronization mechanisms beyond those required for thread safety to ensure this.

Just want to let you guys know, the accepted answer doesn't always work.

Here's an example it will fail.

if <href='/list'>

href = $('css_selector').attr('href')
"/list"
href = document.querySelector('css_selector').href
"http://localhost/list"

or you could append the href you got from jQuery to this

href = document.URL +$('css_selector').attr('href');

or jQuery way

href = $('css_selector').prop('href')

Finally, invoke it to change the browser current page's url

window.location.href = href

or pop it out using window.open(url)

Here's an example in JSFiddle.

This is a summary of a Wikipedia article. It specifies the different types of relationships you can stipulate in PHPmyadmin. I am putting it here because it is relevant to @Nathan's comment on setting the foreign keys options for "on update/delete" but is too large for a comment - hope it helps.

CASCADE

Whenever rows in the master (referenced) table are deleted (resp. updated), the respective rows of the child (referencing) table with a matching foreign key column will get deleted (resp. updated) as well. This is called a cascade delete (resp. update[2]).

RESTRICT

A value cannot be updated or deleted when a row exists in a foreign key table that references the value in the referenced table. Similarly, a row cannot be deleted as long as there is a reference to it from a foreign key table.

NO ACTION

NO ACTION and RESTRICT are very much alike. The main difference between NO ACTION and RESTRICT is that with NO ACTION the referential integrity check is done after trying to alter the table. RESTRICT does the check before trying to execute the UPDATE or DELETE statement. Both referential actions act the same if the referential integrity check fails: the UPDATE or DELETE statement will result in an error.

SET NULL

The foreign key values in the referencing row are set to NULL when the referenced row is updated or deleted. This is only possible if the respective columns in the referencing table are nullable. Due to the semantics of NULL, a referencing row with NULLs in the foreign key columns does not require a referenced row.

SET DEFAULT

Similar to SET NULL, the foreign key values in the referencing row are set to the column default when the referenced row is updated or deleted.

Add a limit to the delete query

delete from orders 
where id_users = 1 and id_product = 2
limit 1

Go to Run type services.msc. Check whether or not MySQL services are running. If not, start it manually. Once it is started, type MySQL Show to test the service.

The second question is easier to answer: you basically can use PyPy as a drop-in replacement if all your code is pure Python. However, many widely used libraries (including some of the standard library) are written in C and compiled as Python extensions. Some of these can be made to work with PyPy, some can't. PyPy provides the same "forward-facing" tool as Python --- that is, it is Python --- but its innards are different, so tools that interface with those innards won't work.

As for the first question, I imagine it is sort of a Catch-22 with the first: PyPy has been evolving rapidly in an effort to improve speed and enhance interoperability with other code. This has made it more experimental than official.

I think it's possible that if PyPy gets into a stable state, it may start getting more widely used. I also think it would be great for Python to move away from its C underpinnings. But it won't happen for a while. PyPy hasn't yet reached the critical mass where it is almost useful enough on its own to do everything you'd want, which would motivate people to fill in the gaps.

According to some comments on Super User it still works :) It just should be copied back to the plugins folder (if it's in the disabled folder) or downloaded from Plugins Central. I have downloaded it a few minutes ago and succeeded in using it.

Of course, be warned: this plugin COULD be unstable in some situations - that's why it was disabled.

I have posted a similar solution for the same problem,

To make a note on Dick's answer, this is correct, but I would not recommend using a For Each loop. For Each creates a temporary reference to the COM Cell behind the scenes that you do not have access to (that you would need in order to dispose of it).

See the following for more discussion:

How do I properly clean up Excel interop objects?

To illustrate the issue, try the For Each example, close your application, and look at Task Manager. You should see that an instance of Excel is still running (because all objects were not disposed of properly).

A cleaner way to handle this is to query the spreadsheet using ADO:

If you want it in crlf (Windows Eol), go to File -> Preferences -> Settings. Type "end of line" in the User tab and make sure Files: Eol is set to \r\n and if you're using the Prettier extension, make sure Prettier: End of Line is set to crlf. Finally, on your eslintrc file, add this rule: 'linebreak-style': ['error', 'windows']

If this is an Observable being return in the HTML simply add the async pipe

    observable | async

For mac users: in terminal command :

unzip yourWARfileName.war

I find that using the var keyword actually makes the code more readable because you just get used to skipping the 'var' keyword. You don't need to keep scrolling right to figure out what the code is doing when you really don't care about what the specific type is. If I really need to know what type 'item' is below, I just hover my mouse over it and Visual Studio will tell me. In other words, I would much rather read

foreach( var item in list ) { DoWork( item ); }

over and over than

foreach( KeyValuePair<string, double> entry in list ) { DoWork( Item ); }

when I am trying to digest the code. I think it boils down to personal preference to some extent. I would rely on common sense on this one -- save enforcing standards for the important stuff (security, database use, logging, etc.)

You can use a LENGTH(that_string) minus the number of characters you want to remove in the SUBSTRING() select perhaps or use the TRIM() function.

For the final, compiled code of your application, the short answer is “no”. Different tools are able to extract different information from the code (e.g. the forms setups) and there are P code decompilers (see Edgar's excellent link for such tools). However, up to this day, there is no decompiler for native code. I'm not aware of anything similar for other high-level languages either.

Did you try showing your window using the ShowDialog method?

Don't forget to set the Owner property on the dialog window to the main window. This will avoid weird behavior when Alt+Tabbing, etc.

Simple solution source='category.name' where category is foreign key and .name it's attribute.

from rest_framework.serializers import ModelSerializer, ReadOnlyField
from my_app.models import Item

class ItemSerializer(ModelSerializer):
    category_name = ReadOnlyField(source='category.name')

    class Meta:
        model = Item
        fields = "__all__"

Unfortunately there is no way to initialize array members till C++0x.

You could use a std::vector and push_back the Foo instances in the constructor body.

You could give Foo a default constructor (might be private and making Baz a friend).

You could use an array object that is copyable (boost or std::tr1) and initialize from a static array:

#include <boost/array.hpp>

struct Baz {

    boost::array<Foo, 3> foo;
    static boost::array<Foo, 3> initFoo;
    Baz() : foo(initFoo)
    {

    }
};

boost::array<Foo, 3> Baz::initFoo = { 4, 5, 6 };

Try this;

@media print{ @page { margin-top: 30px; margin-bottom: 30px;}}

In codeigniter there is no need to sennd "data" in ajax post method.. here is the example .

   searchThis = 'This text will be search';
    $.ajax({
      type: "POST",
      url: "<?php echo site_url();?>/software/search/"+searchThis,
      dataType: "html",
      success:function(data){
        alert(data);
      },

    });

Note : in url , software is the controller name , search is the function name and searchThis is the variable that i m sending.

Here is the controller.

    public function search(){
    $search = $this->uri->segment(3);
      echo '<p>'.$search.'</p>';
    }

I hope you can get idea for your work .

I don't know if Boost has anything that would help.

My preferred pattern is simple: take a template argument which is equal to value_type, either const qualified or not. If necessary, also a node type. Then, well, everything kind of falls into place.

Just remember to parameterize (template-ize) everything that needs to be, including the copy constructor and operator==. For the most part, the semantics of const will create correct behavior.

template< class ValueType, class NodeType >
struct my_iterator
 : std::iterator< std::bidirectional_iterator_tag, T > {
    ValueType &operator*() { return cur->payload; }

    template< class VT2, class NT2 >
    friend bool operator==
        ( my_iterator const &lhs, my_iterator< VT2, NT2 > const &rhs );

    // etc.

private:
    NodeType *cur;

    friend class my_container;
    my_iterator( NodeType * ); // private constructor for begin, end
};

typedef my_iterator< T, my_node< T > > iterator;
typedef my_iterator< T const, my_node< T > const > const_iterator;

React router V4 now allows the history prop to be used as below:

this.props.history.push("/dummy",value)

The value then can be accessed wherever the location prop is available as state:{value} not component state.

As you can see in the generated SQL statements the difference is not the "OR" as some may suspect. It is how the WHERE and JOIN is placed.

Example1 (same joined table) :

(example from https://docs.djangoproject.com/en/dev/topics/db/queries/#spanning-multi-valued-relationships)

Blog.objects.filter(entry__headline__contains='Lennon', entry__pub_date__year=2008)

This will give you all the Blogs that have one entry with both (entry_headline_contains='Lennon') AND (entry__pub_date__year=2008), which is what you would expect from this query. Result: Book with {entry.headline: 'Life of Lennon', entry.pub_date: '2008'}

Example 2 (chained)

Blog.objects.filter(entry__headline__contains='Lennon').filter(entry__pub_date__year=2008)

This will cover all the results from Example 1, but it will generate slightly more result. Because it first filters all the blogs with (entry_headline_contains='Lennon') and then from the result filters (entry__pub_date__year=2008).

The difference is that it will also give you results like: Book with {entry.headline: 'Lennon', entry.pub_date: 2000}, {entry.headline: 'Bill', entry.pub_date: 2008}

In your case

I think it is this one you need:

Book.objects.filter(inventory__user__profile__vacation=False, inventory__user__profile__country='BR')

And if you want to use OR please read: https://docs.djangoproject.com/en/dev/topics/db/queries/#complex-lookups-with-q-objects

Variation of Marc Gravell's simplest solution for .NET 4:

control.Invoke((MethodInvoker) (() => control.Text = "new text"));

Or use Action delegate instead:

control.Invoke(new Action(() => control.Text = "new text"));

See here for a comparison of the two: MethodInvoker vs Action for Control.BeginInvoke

To kill process on a specific port, you can try this

npx kill-port [port-number]

You need to use ScriptManager.RegisterStartupScript for Ajax.

protected void ButtonPP_Click(object sender, EventArgs e) {     if (radioBtnACO.SelectedIndex < 0)     {         string csname1 = "PopupScript";          var cstext1 = new StringBuilder();         cstext1.Append("alert('Please Select Criteria!')");          ScriptManager.RegisterStartupScript(this, GetType(), csname1,             cstext1.ToString(), true);     } } 

You could use zip:

>>> lst=[[1,2,3],[11,12,13],[21,22,23]]
>>> zip(*lst)[0]
(1, 11, 21)

Or, Python 3 where zip does not produce a list:

>>> list(zip(*lst))[0]
(1, 11, 21)

Or,

>>> next(zip(*lst))
(1, 11, 21)

Or, (my favorite) use numpy:

>>> import numpy as np
>>> a=np.array([[1,2,3],[11,12,13],[21,22,23]])
>>> a
array([[ 1,  2,  3],
       [11, 12, 13],
       [21, 22, 23]])
>>> a[:,0]
array([ 1, 11, 21])

Implementations

Although the reference implementation of reStructuredText is written in Python, there are reStructuredText parsers in other languages too.

Python - Docutils

The main distribution of reStructuredText is the Python Docutils package. It contains several conversion tools:

• rst2html - from reStructuredText to HTML
• rst2xml - from reStructuredText to XML
• rst2latex - from reStructuredText to LaTeX
• rst2odt - from reStructuredText to ODF Text (word processor) document.
• rst2s5 - from reStructuredText to S5, a Simple Standards-based Slide Show System
• rst2man - from reStructuredText to Man page

Haskell - Pandoc

Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read Markdown and (subsets of) reStructuredText, HTML, and LaTeX, and it can write Markdown, reStructuredText, HTML, LaTeX, ConTeXt, PDF, RTF, DocBook XML, OpenDocument XML, ODT, GNU Texinfo, MediaWiki markup, groff man pages, and S5 HTML slide shows.

There is an Pandoc online tool (POT) to try this library. Unfortunately, compared to the reStructuredText online renderer (ROR),

• POT truncates input rather more shortly. The POT user must render input in chunks that could be rendered whole by the ROR.
• POT output lacks the helpful error messages displayed by the ROR (and generated by docutils)

Java - JRst

JRst is a Java reStructuredText parser. It can currently output HTML, XHTML, DocBook xdoc and PDF, BUT seems to have serious problems: neither PDF or (X)HTML generation works using the current full download, result pages in (X)HTML are empty and PDF generation fails on IO problems with XSL files (not bundled??). Note that the original JRst has been removed from the website; a fork is found on GitHub.

Scala - Laika

Laika is a new library for transforming markup languages to other output formats. Currently it supports input from Markdown and reStructuredText and produce HTML output. The library is written in Scala but should be also usable from Java.

Perl

• Text::Restructured - Perl implementation of reStructuredText parser
• Dotiac::DTL::Addon::markup - Filters to work with common markup languages - support reStructuredText
• Pod::POM::View::Restructured - View for Pod::POM that outputs reStructuredText

PHP

• Gregwar/RST - A mature PHP5.3 parser with tests
• php-restructuredtext - A simple, incomplete (but functional) implementation

C#/.NET

• reStructuredText for ANTLR - A C# based parser with tests (in progress). It also provides the language server behind reStructuredText extension for Visual Studio Code.

Nim/C

The Nim compiler features the commands rst2htmland rst2tex which transform reStructuredText files to HTML and TeX files. The standard library provides the following modules (used by the compiler) to handle reStructuredText files programmatically:

• rst - implements a reStructuredText parser
• rstast - implements an AST for the reStructuredText parser
• rstgen - implements a generator of HTML/Latex from reStructuredText

Other 3rd party converters

Most (but not all) of these tools are based on Docutils (see above) and provide conversion to or from formats that might not be supported by the main distribution.

From reStructuredText

• restview - This pip-installable python package requires docutils, which does the actual rendering. restview's major ease-of-use feature is that, when you save changes to your document(s), it automagically re-renders and re-displays them. restview
  1. starts a small web server
  2. calls docutils to render your document(s) to HTML
  3. calls your device's browser to display the output HTML.
• rst2pdf - from reStructuredText to PDF
• rst2odp - from reStructuredText to ODF Presentation
• rst2beamer - from reStructuredText to LaTeX beamer Presentation class
• Wikir - from reStructuredText to a Google (and possibly other) Wiki formats
• rst2qhc - Convert a collection of reStructuredText files into a Qt (toolkit) Help file and (optional) a Qt Help Project file

To reStructuredText

• xml2rst is an XSLT script to convert Docutils internal XML representation (back) to reStructuredText
• Pandoc (see above) can also convert from Markdown, HTML and LaTeX to reStructuredText
• db2rst is a simple and limited DocBook to reStructuredText translator
• pod2rst - convert .pod files to reStructuredText files

Extensions

Some projects use reStructuredText as a baseline to build on, or provide extra functionality extending the utility of the reStructuredText tools.

Sphinx

The Sphinx documentation generator translates a set of reStructuredText source files into various output formats, automatically producing cross-references, indices etc.

rest2web

rest2web is a simple tool that lets you build your website from a single template (or as many as you want), and keep the contents in reStructuredText.

Pygments

Pygments is a generic syntax highlighter for general use in all kinds of software such as forum systems, Wikis or other applications that need to prettify source code. See Using Pygments in reStructuredText documents.

Free Editors

While any plain text editor is suitable to write reStructuredText documents, some editors have better support than others.

Emacs

The Emacs support via rst-mode comes as part of the Docutils package under /docutils/tools/editors/emacs/rst.el

Vim

The vim-common package for that comes with most GNU/Linux distributions has reStructuredText syntax highlight and indentation support of reStructuredText out of the box:

• reStructuredText syntax highlighting mode for vim
• VST (Vim reStructured Text) is a plugin for Vim7 with folding for reStructuredText
• Riv.vim - fresh vim plugin for authoring rst and Sphinx doc
• Previm: Vim plugin for live previewing of reStructuredText and other mark up documents

Jed

There is a rst mode for the Jed programmers editor.

gedit

gedit, the official text editor of the GNOME desktop environment. There is a gedit reStructuredText plugin.

Geany

Geany, a small and lightweight Integrated Development Environment include support for reStructuredText from version 0.12 (October 10, 2007).

Leo

Leo, an outlining editor for programmers, supports reStructuredText via rst-plugin or via "@auto-rst" nodes (it's not well-documented, but @auto-rst nodes allow editing rst files directly, parsing the structure into the Leo outline).

It also provides a way to preview the resulting HTML, in a "viewrendered" pane.

FTE

The FTE Folding Text Editor - a free (licensed under the GNU GPL) text editor for developers. FTE has a mode for reStructuredText support. It provides color highlighting of basic RSTX elements and special menu that provide easy way to insert most popular RSTX elements to a document.

PyK

PyK is a successor of PyEdit and reStInPeace, written in Python with the help of the Qt4 toolkit.

Eclipse

The Eclipse IDE with the ReST Editor plug-in provides support for editing reStructuredText files.

NoTex

NoTex is a browser based (general purpose) text editor, with integrated project management and syntax highlighting. Plus it enables to write books, reports, articles etc. using rST and convert them to LaTex, PDF or HTML. The PDF files are of high publication quality and are produced via Sphinx with the Texlive LaTex suite.

Notepad++

Notepad++ is a general purpose text editor for Windows. It has syntax highlighting for many languages built-in and support for reStructuredText via a user defined language for reStructuredText.

Visual Studio Code

Visual Studio Code is a general purpose text editor for Windows/macOS/Linux. It has syntax highlighting for many languages built-in and supports reStructuredText via an extension from LeXtudio.

Dedicated reStructuredText Editors

• ReSTedit by Dinu Gherman and Bill Bumgarner
• Rest in Peace
• Enthought Tool Suite editor
• ReText a cross platform program that works like Marked.
• RSTPad a standalone cross-platform editor with live preview

Proprietary editors

Sublime Text

Sublime Text is a completely customizable and extensible source code editor available for Windows, OS X, and Linux. Registration is required for long-term use, but all functions are available in the unregistered version, with occasional reminders to purchase a license. Versions 2 and 3 (currently in beta) support reStructuredText syntax highlighting by default, and several plugins are available through the package manager Package Control to provide snippets and code completion, additional syntax highlighting, conversion to/from RST and other formats, and HTML preview in the browser.

BBEdit / TextWrangler

BBEdit (and its free variant TextWrangler) for Mac can syntax-highlight reStructuredText using this codeless language module.

TextMate

TextMate, a proprietary general-purpose GUI text editor for Mac OS X, has a bundle for reStructuredText.

Intype

Intype is a proprietary text editor for Windows, that support reStructuredText out of the box.

E Text Editor

E is a proprietary Text Editor licensed under the "Open Company License". It supports TextMate's bundles, so it should support reStructuredText the same way TextMate does.

PyCharm

PyCharm (and other IntelliJ platform IDEs?) has ReST/Sphinx support (syntax highlighting, autocomplete and preview).)

Wiki

here are some Wiki programs that support the reStructuredText markup as the native markup syntax, or as an add-on:

MediaWiki

MediaWiki reStructuredText extension allows for reStructuredText markup in MediaWiki surrounded by <rst> and </rst>.

MoinMoin

MoinMoin is an advanced, easy to use and extensible WikiEngine with a large community of users. Said in a few words, it is about collaboration on easily editable web pages.

This Wiki

This Wiki is a Webware for Python Wiki written by Ian Bicking. This wiki uses ReStructuredText for its markup.

rstiki

rstiki is a minimalist single-file personal wiki using reStructuredText syntax (via docutils) inspired by pwyky. It does not support authorship indication, versioning, hierarchy, chrome/framing/templating or styling. It leverages docutils/reStructuredText as the wiki syntax. As such, it's under 200 lines of code, and in a single file. You put it in a directory and it runs.

ikiwiki

Ikiwiki is a wiki compiler. It converts wiki pages into HTML pages suitable for publishing on a website. Ikiwiki stores pages and history in a revision control system such as Subversion or Git. There are many other features, including support for blogging, as well as a large array of plugins. It's reStructuredText plugin, however is somewhat limited and is not recommended as its' main markup language at this time.

You can use gdb, but I would first try Valgrind. See the quick start guide.

Briefly, Valgrind instruments your program so it can detect several kinds of errors in using dynamically allocated memory, such as double frees and writes past the end of allocated blocks of memory (which can corrupt the heap). It detects and reports the errors as soon as they occur, thus pointing you directly to the cause of the problem.

A simple accidental way is to do a git checkout head as a typo of HEAD.

Try this:

git init
touch Readme.md
git add Readme.md
git commit
git checkout head

which gives

Note: checking out 'head'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now at 9354043... Readme

Another good solution to read and write CSV-files is filehelpers (open source).

A process is a collection of code, memory, data and other resources. A thread is a sequence of code that is executed within the scope of the process. You can (usually) have multiple threads executing concurrently within the same process.

If you are suffering from "ADB not responding. If you’d like to retry, then please manually kill ‘adb’ and click ‘Restart’ or terminal appear Syntax error: “)” unexpected" then perhaps you are using 32bit OS and platform-tools has updated up 23.1. The solution is to go back to the platform-tools 23.0.1.

You can download the platform-tools 23.0.1 for Linux here , for windowns here and Mac here

After the download, go to your sdk location > platform-tools folder to delete old platform-tools in sdk and paste down into the downloaded one.

Woohooo ... it should work.

This is a bug with latest ADT.

You can do this in Oracle 12.1 or above:

declare
    rc sys_refcursor;
begin
    open rc for select * from dual;
    dbms_sql.return_result(rc);
end;

I don't have DBVisualizer to test with, but that should probably be your starting point.

For more details, see Implicit Result Sets in the Oracle 12.1 New Features Guide, Oracle Base etc.

For earlier versions, depending on the tool you might be able to use ref cursor bind variables like this example from SQL*Plus:

set autoprint on

var rc refcursor

begin
    open :rc for select count(*) from dual;
end;
/

PL/SQL procedure successfully completed.


  COUNT(*)

"Conflicts" mean "parallel evolutions of a same content". So if it goes "all to hell" during a merge, it means you have massive evolutions on the same set of files.

The reason why a rebase is then better than a merge is that:

• you rewrite your local commit history with the one of the master (and then reapply your work, resolving any conflict then)
• the final merge will certainly be a "fast forward" one, because it will have all the commit history of the master, plus only your changes to reapply.

I confirm that the correct workflow in that case (evolutions on common set of files) is rebase first, then merge.

However, that means that, if you push your local branch (for backup reason), that branch should not be pulled (or at least used) by anyone else (since the commit history will be rewritten by the successive rebase).

On that topic (rebase then merge workflow), barraponto mentions in the comments two interesting posts, both from randyfay.com:

• A Rebase Workflow for Git: reminds us to fetch first, rebase:

Using this technique, your work always goes on top of the public branch like a patch that is up-to-date with current HEAD.

(a similar technique exists for bazaar)

• Avoiding Git Disasters: A Gory Story: about the dangers of git push --force (instead of a git pull --rebase for instance)

You can also use the good old micro clearfix for this.

#container::before, #container::after{
    content: ' ';
    display: table;
}

1. Flyweight is used with some values of Byte, Short, Integer, Long and String.
2. Facade is used in many place but the most obvious is Scripting interfaces.
3. Singleton - java.lang.Runtime comes to mind.
4. Abstract Factory - Also Scripting and JDBC API.
5. Command - TextComponent's Undo/Redo.
6. Interpreter - RegEx (java.util.regex.) and SQL (java.sql.) API.
7. Prototype - Not 100% sure if this count, but I thinkg clone() method can be used for this purpose.

I don't think this DateTimePicker has been mentioned before:

A WPF DateTimePicker That Works Like the One in Winforms

That one is in VB and has some bugs. I converted it to C# and made a new version with bug fixes.

Note: I used the Calendar control in WPFToolkit so that I could use .NET 3.5 instead of .NET 4. If you are using .NET 4, just remove references to "wpftc" in the XAML.

The post Reset Demystified in the blog Pro Git gives a very no-brainer explanation on git reset and git checkout.

After all the helpful discussion at the top of that post, the author reduces the rules to the following simple three steps:

That is basically it. The reset command overwrites these three trees in a specific order, stopping when you tell it to.

1. Move whatever branch HEAD points to (stop if --soft)
2. THEN, make the Index look like that (stop here unless --hard)
3. THEN, make the Working Directory look like that

There are also --merge and --keep options, but I would rather keep things simpler for now - that will be for another article.

extension String {

    var numberValue:NSNumber? {
        let formatter = NumberFormatter()
        formatter.numberStyle = .decimal
        return formatter.number(from: self)
    }
}

let someFloat = "12.34".numberValue

There`s my solution. It will compare arrays which also have objects and arrays. Elements can be stay in any positions. Example:

const array1 = [{a: 1}, {b: 2}, { c: 0, d: { e: 1, f: 2, } }, [1,2,3,54]];
const array2 = [{a: 1}, {b: 2}, { c: 0, d: { e: 1, f: 2, } }, [1,2,3,54]];

const arraysCompare = (a1, a2) => {
  if (a1.length !== a2.length) return false;
  const objectIteration = (object) => {
    const result = [];
    const objectReduce = (obj) => {
      for (let i in obj) {
        if (typeof obj[i] !== 'object') {
          result.push(`${i}${obj[i]}`);
        } else {
          objectReduce(obj[i]);
        }
      }
    };
    objectReduce(object);
    return result;
  };
  const reduceArray1 = a1.map(item => {
    if (typeof item !== 'object') return item;
    return objectIteration(item).join('');
  });
  const reduceArray2 = a2.map(item => {
    if (typeof item !== 'object') return item;
    return objectIteration(item).join('');
  });
  const compare =  reduceArray1.map(item => reduceArray2.includes(item));
  return compare.reduce((acc, item) => acc + Number(item)) === a1.length;
};

console.log(arraysCompare(array1, array2));

Late to the party, but I think this addition might be useful for people working with rmarkdown. In rmarkdown there is built-in support for references to headers in your document.

Any header defined by

# Header

can be referenced by

get me back to that [header](#header)

The following is a minimal standalone .rmd file that shows this behavior. It can be knitted to .pdf and .html.

---
title: "references in rmarkdown"
output:
  html_document: default
  pdf_document: default
---

# Header

Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. 

Go back to that [header](#header).

Make a drawable file, striking_text.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="false">
        <shape android:shape="line">
            <stroke android:width="1dp" android:color="@android:color/holo_red_dark" />
        </shape>
    </item>
</selector>

layout xml

 <TextView
            ....
            ....
            android:background="@drawable/striking_text"
            android:foreground="@drawable/striking_text"
            android:text="69$"
           />

If your min SDK below API level 23 just use the background or just put the background and foreground in the Textview then the android studio will show an error that says create a layout file for API >23 after that remove the android:foreground="@drawable/stricking_text" from the main layout

Output look like this:

One thing you can do is get rid of all those onclick attributes and do it the right way with bootstrap. You don't need to open them manually; you can specify the trigger and even subscribe to events before the modal opens so that you can do your operations and populate data in it.

I am just going to show as a static example which you can accommodate in your real world.

On each of your <tr>'s add a data attribute for id (i.e. data-id) with the corresponding id value and specify a data-target, which is a selector you specify, so that when clicked, bootstrap will select that element as modal dialog and show it. And then you need to add another attribute data-toggle=modal to make this a trigger for modal.

  <tr data-toggle="modal" data-id="1" data-target="#orderModal">
            <td>1</td>
            <td>24234234</td>
            <td>A</td>
  </tr>
  <tr data-toggle="modal" data-id="2" data-target="#orderModal">
            <td>2</td>
            <td>24234234</td>
            <td>A</td>
        </tr>
  <tr data-toggle="modal" data-id="3" data-target="#orderModal">
            <td>3</td>
            <td>24234234</td>
            <td>A</td>
  </tr>

And now in the javascript just set up the modal just once and event listen to its events so you can do your work.

$(function(){
    $('#orderModal').modal({
        keyboard: true,
        backdrop: "static",
        show:false,

    }).on('show', function(){ //subscribe to show method
          var getIdFromRow = $(event.target).closest('tr').data('id'); //get the id from tr
        //make your ajax call populate items or what even you need
        $(this).find('#orderDetails').html($('<b> Order Id selected: ' + getIdFromRow  + '</b>'))
    });
});

Demo

Do not use inline click attributes any more. Use event bindings instead with vanilla js or using jquery.

Instead of changing CSS values one by one I would suggest to use LESS. Bootstrap has LESS version on Github: https://github.com/twbs/bootstrap

LESS allows you to define variables to change colors which makes it so much more convenient. Define color once and LESS compiles CSS file that changes the values globally. Saves time and effort.

Try a \<Space> before 12, like so:

:set guifont=Monospace\ 12

In Amazon Java SDK 1.10+, you can use getStatusCode() to get the status code of the HTTP response, which will be 404 if the object does not exist.

import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.model.AmazonS3Exception;
import org.apache.http.HttpStatus;

try {
    AmazonS3 s3 = new AmazonS3Client();
    ObjectMetadata object = s3.getObjectMetadata("my-bucket", "my-client");
} catch (AmazonS3Exception e) {
    if (e.getStatusCode() == HttpStatus.SC_NOT_FOUND) {
        // bucket/key does not exist 
    } else {
        throw e;
    }
}

getObjectMetadata() consumes fewer resources, and the response doesn't need to be closed like getObject().

In previous versions, you can use getErrorCode() and check for the appropriate string (depends on the version).

If you have too many installers to find what you are looking for easily, here is some powershell to provide a filter and narrow it down a little by display name.

$filter = "*core*sdk*"; (Get-ChildItem HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall).Name | % { $path = "Registry::$_"; Get-ItemProperty $path } | Where-Object { $_.DisplayName -like $filter } | Select-Object -Property DisplayName, PsChildName

A more general way of achieving column type transformation is as follows:

If you want to transform all your factor columns to character columns, e.g., this can be done using one pipe:

df %>%  mutate_each_( funs(as.character(.)), names( .[,sapply(., is.factor)] ))

you cannot set this in javascript, you have to do this with html/css:

<style type="text/css" media="print">
  @page { size: landscape; }
</style>

EDIT: See this Question and the accepted answer for more information on browser support: Is @Page { size:landscape} obsolete?

I believe you already found the issue, but in my case helped to simply install the Microsoft.NET.Test.Sdk. Make sure you add it to your test project. I've spent few days trying to solve the problem and it's as simple as that.

Microsoft.Net.Test.Sdk should be installed no matter what testing framework you are using.

One easy solution is to use overflow values other than visible to make the text flex basis width reset as expected.

1. Here with value auto the text wraps as expected and the article content does not overflow main container.

2. Also, the article flex value must either have a auto basis AND be able to shrink, OR, only grow AND explicit 0 basis

main, aside, article {_x000D_
  margin: 10px;_x000D_
  border: solid 1px #000;_x000D_
  border-bottom: 0;_x000D_
  height: 50px;_x000D_
  overflow: auto; /* 1. overflow not `visible` */_x000D_
}_x000D_
main {_x000D_
  display: flex;_x000D_
}_x000D_
aside {_x000D_
  flex: 0 0 200px;_x000D_
}_x000D_
article {_x000D_
  flex: 1 1 auto; /* 2. Allow auto width content to shrink */_x000D_
  /* flex: 1 0 0; /* Or, explicit 0 width basis that grows */_x000D_
}

Simple Pass Intent first

Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);

And u will get picture path on u onActivityResult

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };
            Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();
            ImageView imageView = (ImageView) findViewById(R.id.imgView);
            imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
        }
    }

Create a new keypair: (go with the defaults)

ssh-keygen

Copy the public key to the server: (password for the last time)

ssh-copy-id [email protected]

From now on the server should recognize your key and not ask you for the password anymore:

ssh [email protected]

Your query translates to

SELECT * FROM table WHERE id='1' or id='2' or id='3' or id='4';

It will only return the results that match it.

One way of solving it avoiding the complexity would be, chaning the datatype to SET. Then you could use, FIND_IN_SET

SELECT * FROM table WHERE FIND_IN_SET('1', id);

You do not need to use moment-timezone for this. The main moment.js library has full functionality for working with UTC and the local time zone.

var testDateUtc = moment.utc("2015-01-30 10:00:00");
var localDate = moment(testDateUtc).local();

From there you can use any of the functions you might expect:

var s = localDate.format("YYYY-MM-DD HH:mm:ss");
var d = localDate.toDate();
// etc...

Note that by passing testDateUtc, which is a moment object, back into the moment() constructor, it creates a clone. Otherwise, when you called .local(), it would also change the testDateUtc value, instead of just the localDate value. Moments are mutable.

Also note that if your original input contains a time zone offset such as +00:00 or Z, then you can just parse it directly with moment. You don't need to use .utc or .local. For example:

var localDate = moment("2015-01-30T10:00:00Z");

I used these two commands and saved my problem

sudo chown -R $(whoami) /usr/local

sudo chown -R $(whoami) /usr/local/etc/bash_completion.d /usr/local/lib/python3.7/site-packages /usr/local/share/aclocal /usr/local/share/locale /usr/local/share/man/man7 /usr/local/share/man/man8 /usr/local/share/zsh /usr/local/share/zsh/site-functions /usr/local/var/homebrew/locks

Instead of writing the code from the scratch you can use jquery plug in. Such plug in can provide many configuration option as well.

Here is the one I most liked.

http://www.zurb.com/playground/orbit-jquery-image-slider

It sounds like you want something like:

var query = from order in workOrders
            join plan in plans
                 on order.WorkOrderNumber equals plan.WorkOrderNumber
            select new
            {
                order.WorkOrderNumber,
                order.Description,
                plan.ScheduledDate
            };

For those of you with a Chromebook Pixel/Ubuntu/Crouton with no numpad, installing the onboard keyboard worked for me.

Just press 123 to access the numpad layout, and then press 7

If you're on Unity already, onboard may already be installed, so just type onboard from your command line to see if it's there.

If not, just type:

sudo apt-get update

sudo apt-get install onboard

PS: The Chromebook Pixel's upper keys were supposed to represent the traditional F1 through F11 function keys on Ubuntu/Crouton, so you may want to try those special hardware keys first (on their own or in combination with Ctrl). It's just that for me, I'm running an old copy of Crouton, and the only function key that seems to be recognized is F6

Return the list directly. Benefits:

• It's more clear
• The list is reusable. (the iterator is not) not actually true, Thanks Jon

You should use the iterator (yield) from when you think you probably won't have to iterate all the way to the end of the list, or when it has no end. For example, the client calling is going to be searching for the first product that satisfies some predicate, you might consider using the iterator, although that's a contrived example, and there are probably better ways to accomplish it. Basically, if you know in advance that the whole list will need to be calculated, just do it up front. If you think that it won't, then consider using the iterator version.

select the image in chrome, right click on it, click on Copy image address, paste it into a str variable (my_url) to read the image:

Great work from @Avanka!

This code works for me: I set values whit an INSERT and get the LAST_INSERT_ID() of this value whit a SELECT; I use java NetBeans 8.1, MySql and java.JDBC.driver

                try {

        String Query = "INSERT INTO `stock`(`stock`, `min_stock`,   
                `id_stock`) VALUES ("

                + "\"" + p.get_Stock().getStock() + "\", "
                + "\"" + p.get_Stock().getStockMinimo() + "\","
                + "" + "null" + ")";

        Statement st = miConexion.createStatement();
        st.executeUpdate(Query);

        java.sql.ResultSet rs;
        rs = st.executeQuery("Select LAST_INSERT_ID() from stock limit 1");                
        rs.next(); //para posicionar el puntero en la primer fila
        ultimo_id = rs.getInt("LAST_INSERT_ID()");
        } catch (SqlException ex) { ex.printTrace;}

Here is an answer for Swift 4 :

    let textAttributes:[String:Any]? = [NSAttributedStringKey.foregroundColor.rawValue:UIColor.blue, NSAttributedStringKey.font.rawValue:UIFont(name:"Avenir Next", size:20)!]
    navigationController?.navigationBar.titleTextAttributes = textAttributes

I'd like to supplement BalusC's answer with the mapping rules and an example.

Mapping rules from Servlet 2.5 specification:

1. Map exact URL
2. Map wildcard paths
3. Map extensions
4. Map to the default servlet

In our example, there're three servlets. / is the default servlet installed by us. Tomcat installs two servlets to serve jsp and jspx. So to map http://host:port/context/hello

1. No exact URL servlets installed, next.
2. No wildcard paths servlets installed, next.
3. Doesn't match any extensions, next.
4. Map to the default servlet, return.

To map http://host:port/context/hello.jsp

1. No exact URL servlets installed, next.
2. No wildcard paths servlets installed, next.
3. Found extension servlet, return.

Using -s option will print output of all functions, which may be too much.

If you need particular output, the doc page you mentioned offers few suggestions:

1. Insert assert False, "dumb assert to make PyTest print my stuff" at the end of your function, and you will see your output due to failed test.

2. You have special object passed to you by PyTest, and you can write the output into a file to inspect it later, like

   def test_good1(capsys):
       for i in range(5):
           print i
       out, err = capsys.readouterr()
       open("err.txt", "w").write(err)
       open("out.txt", "w").write(out)
   

   You can open the out and err files in a separate tab and let editor automatically refresh it for you, or do a simple py.test; cat out.txt shell command to run your test.

That is rather hackish way to do stuff, but may be it is the stuff you need: after all, TDD means you mess with stuff and leave it clean and silent when it's ready :-).

You don't need to. Just slap it on there as many times as you want and as often as you want. MDN explains identical event listeners:

If multiple identical EventListeners are registered on the same EventTarget with the same parameters, the duplicate instances are discarded. They do not cause the EventListener to be called twice, and they do not need to be removed manually with the removeEventListener method.

Loius answer is correct, I just want to add an example:

listOne.add("A");
listOne.add("B");
listOne.add("C");

listTwo.add("D");
listTwo.add("E");
listTwo.add("F");      

boolean noElementsInCommon = Collections.disjoint(listOne, listTwo); // true

Don't use keyworks like "ad", "ads", "advertise", etc. in image url or image class. Adblock block them automatically.

DotNetZip is your friend here.

As easy as:

using (ZipFile zip = ZipFile.Read(ExistingZipFile))
{
  ZipEntry e = zip["MyReport.doc"];
  e.Extract(OutputStream);
}

(you can also extract to a file or other destinations).

Reading the zip file's table of contents is as easy as:

using (ZipFile zip = ZipFile.Read(ExistingZipFile))
{
  foreach (ZipEntry e in zip)
  {
    if (header)
    {
      System.Console.WriteLine("Zipfile: {0}", zip.Name);
      if ((zip.Comment != null) && (zip.Comment != "")) 
        System.Console.WriteLine("Comment: {0}", zip.Comment);
      System.Console.WriteLine("\n{1,-22} {2,8}  {3,5}   {4,8}  {5,3} {0}",
                               "Filename", "Modified", "Size", "Ratio", "Packed", "pw?");
      System.Console.WriteLine(new System.String('-', 72));
      header = false;
    }
    System.Console.WriteLine("{1,-22} {2,8} {3,5:F0}%   {4,8}  {5,3} {0}",
                             e.FileName,
                             e.LastModified.ToString("yyyy-MM-dd HH:mm:ss"),
                             e.UncompressedSize,
                             e.CompressionRatio,
                             e.CompressedSize,
                             (e.UsesEncryption) ? "Y" : "N");

  }
}

Edited To Note: DotNetZip used to live at Codeplex. Codeplex has been shut down. The old archive is still available at Codeplex. It looks like the code has migrated to Github:

• https://github.com/DinoChiesa/DotNetZip. Looks to be the original author's repo.
• https://github.com/haf/DotNetZip.Semverd. This looks to be the currently maintained version. It's also packaged up an available via Nuget at https://www.nuget.org/packages/DotNetZip/

Try this

`var url = "http://stackoverflow.com";    
$(location).attr('href',url);`

Or you can do something like this

// similar behavior as an HTTP redirect
window.location.replace("http://stackoverflow.com");

// similar behavior as clicking on a link
window.location.href = "http://stackoverflow.com";

and add a return false at the end of your function call

You can use Caller Information and optional parameters:

public static string WhoseThere([CallerMemberName] string memberName = "")
{
       return memberName;
}

This test illustrates this:

[Test]
public void Should_get_name_of_calling_method()
{
    var methodName = CachingHelpers.WhoseThere();
    Assert.That(methodName, Is.EqualTo("Should_get_name_of_calling_method"));
}

While the StackTrace works quite fast above and would not be a performance issue in most cases the Caller Information is much faster still. In a sample of 1000 iterations, I clocked it as 40 times faster.

If you are not sharing develop branch with anybody, then I would just rebase it every time master updated, that way you will not have merge commits all over your history once you will merge develop back into master. Workflow in this case would be as follows:

> git clone git://<remote_repo_path>/ <local_repo>
> cd <local_repo>
> git checkout -b develop
....do a lot of work on develop
....do all the commits
> git pull origin master
> git rebase master develop

Above steps will ensure that your develop branch will be always on top of the latest changes from the master branch. Once you are done with develop branch and it's rebased to the latest changes on master you can just merge it back:

> git checkout -b master
> git merge develop
> git branch -d develop

I have the same problem like you and luckily I have read the solution from this link: http://access-excel.tips/value-before-worksheet-change/

Dim oldValue As Variant
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    oldValue = Target.Value
End Sub
Private Sub Worksheet_Change(ByVal Target As Range)
    'do something with oldValue...
End Sub

Note: you must place oldValue variable as a global variable so all subclasses can use it.

I think this is what you want, I already tested this code and works

The tools used are: (all these tools can be downloaded as Nuget packages)

http://fluentassertions.codeplex.com/

http://autofixture.codeplex.com/

http://code.google.com/p/moq/

https://nuget.org/packages/AutoFixture.AutoMoq

var fixture = new Fixture().Customize(new AutoMoqCustomization());
var myInterface = fixture.Freeze<Mock<IFileConnection>>();

var sut = fixture.CreateAnonymous<Transfer>();

myInterface.Setup(x => x.Get(It.IsAny<string>(), It.IsAny<string>()))
        .Throws<System.IO.IOException>();

sut.Invoking(x => 
        x.TransferFiles(
            myInterface.Object, 
            It.IsAny<string>(), 
            It.IsAny<string>()
        ))
        .ShouldThrow<System.IO.IOException>();

Edited:

Let me explain:

When you write a test, you must know exactly what you want to test, this is called: "subject under test (SUT)", if my understanding is correctly, in this case your SUT is: Transfer

So with this in mind, you should not mock your SUT, if you substitute your SUT, then you wouldn't be actually testing the real code

When your SUT has external dependencies (very common) then you need to substitute them in order to test in isolation your SUT. When I say substitute I'm referring to use a mock, dummy, mock, etc depending on your needs

In this case your external dependency is IFileConnection so you need to create mock for this dependency and configure it to throw the exception, then just call your SUT real method and assert your method handles the exception as expected

• var fixture = new Fixture().Customize(new AutoMoqCustomization());: This linie initializes a new Fixture object (Autofixture library), this object is used to create SUT's without having to explicitly have to worry about the constructor parameters, since they are created automatically or mocked, in this case using Moq

• var myInterface = fixture.Freeze<Mock<IFileConnection>>();: This freezes the IFileConnection dependency. Freeze means that Autofixture will use always this dependency when asked, like a singleton for simplicity. But the interesting part is that we are creating a Mock of this dependency, you can use all the Moq methods, since this is a simple Moq object

• var sut = fixture.CreateAnonymous<Transfer>();: Here AutoFixture is creating the SUT for us

• myInterface.Setup(x => x.Get(It.IsAny<string>(), It.IsAny<string>())).Throws<System.IO.IOException>(); Here you are configuring the dependency to throw an exception whenever the Get method is called, the rest of the methods from this interface are not being configured, therefore if you try to access them you will get an unexpected exception

• sut.Invoking(x => x.TransferFiles(myInterface.Object, It.IsAny<string>(), It.IsAny<string>())).ShouldThrow<System.IO.IOException>();: And finally, the time to test your SUT, this line uses the FluenAssertions library, and it just calls the TransferFiles real method from the SUT and as parameters it receives the mocked IFileConnection so whenever you call the IFileConnection.Get in the normal flow of your SUT TransferFiles method, the mocked object will be invoking throwing the configured exception and this is the time to assert that your SUT is handling correctly the exception, in this case, I am just assuring that the exception was thrown by using the ShouldThrow<System.IO.IOException>() (from the FluentAssertions library)

///UPDATED DEMO 2 WATCH SOLUTION////

I hope that is the solution you're looking for! DEMO1 DEMO2

With that solution the only scrollbar in the page is on your contents section in the middle! In that section build your structure with a sidebar or whatever you want!

You can do that with that code here:

<div class="navTop">
<h1>Title</h1>
    <nav>Dynamic menu</nav>
</div>
<div class="container">
    <section>THE CONTENTS GOES HERE</section>
</div>
<footer class="bottomFooter">
    Footer
</footer>

With that css:

.navTop{
width:100%;
border:1px solid black;
float:left;
}
.container{
width:100%;
float:left;
overflow:scroll;
}
.bottomFooter{
float:left;
border:1px solid black;
width:100%;
}

And a bit of jquery:

$(document).ready(function() {
  function setHeight() {
    var top = $('.navTop').outerHeight();
    var bottom = $('footer').outerHeight();
    var totHeight = $(window).height();
    $('section').css({ 
      'height': totHeight - top - bottom + 'px'
    });
  }

  $(window).on('resize', function() { setHeight(); });
  setHeight();
});

As the other answers said, the function you need is cv2.rectangle(), but keep in mind that the coordinates for the bounding box vertices need to be integers if they are in a tuple, and they need to be in the order of (left, top) and (right, bottom). Or, equivalently, (xmin, ymin) and (xmax, ymax).

The differences between strong and retain:

• In iOS4, strong is equal to retain
• It means that you own the object and keep it in the heap until don’t point to it anymore
• If you write retain it will automatically work just like strong

The differences between weak and assign:

• A “weak” reference is a reference that you don’t retain and you keep it as long as someone else points to it strongly
• When the object is “deallocated”, the weak pointer is automatically set to nil
• A "assign" property attribute tells the compiler how to synthesize the property’s setter implementation

I know this is an old question, but thought that I should anyway present the simple solution using the paste() function as suggested to by the questioner:

data_1<-data.frame(a=data$a,"x"=paste(data$b,data$c,data$d,sep="-")) 
data_1
  a     x
1 1 a-d-g
2 2 b-e-h
3 3 c-f-i

Or if you use gmaps.js, call:

map.refresh();

when your div is shown.

EDIT: The solution below is only for HTML "fragments" since html,head and body are removed. I guess the solution for this question is DOMParser's parseFromString() method.

For HTML fragments, the solutions listed here works for most HTML, however for certain cases it won't work.

For example try parsing <td>Test</td>. This one won't work on the div.innerHTML solution nor DOMParser.prototype.parseFromString nor range.createContextualFragment solution. The td tag goes missing and only the text remains.

Only jQuery handles that case well.

So the future solution (MS Edge 13+) is to use template tag:

function parseHTML(html) {
    var t = document.createElement('template');
    t.innerHTML = html;
    return t.content.cloneNode(true);
}

var documentFragment = parseHTML('<td>Test</td>');

For older browsers I have extracted jQuery's parseHTML() method into an independent gist - https://gist.github.com/Munawwar/6e6362dbdf77c7865a99

For http/https proxy with or without authentication:

Run one of the following commands in cmd.exe

set http_proxy=http://your_proxy:your_port
set http_proxy=http://username:password@your_proxy:your_port
set https_proxy=https://your_proxy:your_port
set https_proxy=https://username:password@your_proxy:your_port

In my case, I have a PHP web application being served by Apache2 within the docker container that connects to a MYSQL backend database. Larry Cai's solution worked with minor modifications. I created a entrypoint.sh file within which I am managing my services. I think creating an entrypoint.sh when you have more than one command to execute when your container starts up is a cleaner way to bootstrap docker.

#!/bin/sh

set -e

echo "Starting the mysql daemon"
service mysql start

echo "navigating to volume /var/www"
cd /var/www
echo "Creating soft link"
ln -s /opt/mysite mysite

a2enmod headers
service apache2 restart

a2ensite mysite.conf
a2dissite 000-default.conf
service apache2 reload

if [ -z "$1" ]
then
    exec "/usr/sbin/apache2 -D -foreground"
else
    exec "$1"
fi

Btw, I am a great fan of capturing everything and filtering the information later.

What would happen if you were capturing at Warning level and want some Debug info related to the warning, but were unable to recreate the warning?

Capture everything and filter later!

This holds true even for embedded software unless you find that your processor can't keep up, in which case you might want to re-design your tracing to make it more efficient, or the tracing is interfering with timing (you might consider debugging on a more powerful processor, but that opens up a whole nother can of worms).

Capture everything and filter later!!

(btw, capture everything is also good because it lets you develop tools to do more than just show debug trace (I draw Message Sequence Charts from mine, and histograms of memory usage. It also gives you a basis for comparison if something goes wrong in future (keep all logs, whether pass or fail, and be sure to include build number in the log file)).

I would like to add that this problem is similar to common Java memory leaks.

When the JVM garbage collector is unable to clear the "waste" memory of your Java / Java EE application over time, OutOfMemoryError: Java heap space will be the outcome.

It is important to perform a proper diagnostic first:

• Enable verbose:gc. This will allow you to understand the memory growing pattern over time.
• Generate and analyze a JVM Heap Dump. This will allow you to understand your application memory footprint and pinpoint the source of the memory leak(s).
• You can also use Java profilers and runtime memory leak analyzer such as Plumbr as well to help you with this task.

In Layman terms, you need to include external js file in your HTML file & thereafter you could directly call your JS method written in an external js file from HTML page. Follow the code snippet for insight:-

caller.html

<script type="text/javascript" src="external.js"></script>
<input type="button" onclick="letMeCallYou()" value="run external javascript">

external.js

function letMeCallYou()
{
    alert("Bazinga!!!  you called letMeCallYou")
}

Result :

I am a Linux guy. In Linux it is extremely easy with netstat -ltpn or any combination of those letters. But in Mac OS X netstat -an | grep LISTEN is the most humane. Others are very ugly and very difficult to remember when troubleshooting.

Plain old Java on plain old Java 7 and no other dependencies demonstrates the difference...

I put file.txt in c:\temp\ and I put c:\temp\ on the classpath.

There is only one case where there is a difference between the two call.

class J {

 public static void main(String[] a) {
    // as "absolute"

    // ok   
    System.err.println(J.class.getResourceAsStream("/file.txt") != null); 

    // pop            
    System.err.println(J.class.getClassLoader().getResourceAsStream("/file.txt") != null); 

    // as relative

    // ok
    System.err.println(J.class.getResourceAsStream("./file.txt") != null); 

    // ok
    System.err.println(J.class.getClassLoader().getResourceAsStream("./file.txt") != null); 

    // no path

    // ok
    System.err.println(J.class.getResourceAsStream("file.txt") != null); 

   // ok
   System.err.println(J.class.getClassLoader().getResourceAsStream("file.txt") != null); 
  }
}

Attach an event listener to a parent element that fires when an event occurs on a child element.

When an event moves through the DOM from child to a parent element, that's called Event Propagation, because the event propagates, or moves through the DOM.

In this example, an event (onclick) from a button gets passed to the parent paragraph.

$(document).ready(function() {_x000D_
_x000D_
    $(".spoiler span").hide();_x000D_
_x000D_
    /* add event onclick on parent (.spoiler) and delegate its event to child (button) */_x000D_
    $(".spoiler").on( "click", "button", function() {_x000D_
    _x000D_
        $(".spoiler button").hide();    _x000D_
    _x000D_
        $(".spoiler span").show();_x000D_
    _x000D_
    } );_x000D_
_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>_x000D_
_x000D_
<p class="spoiler">_x000D_
    <span>Hello World</span>_x000D_
    <button>Click Me</button>_x000D_
</p>

Codepen

Could you use jQuery, since it's cross-browser compatible?

function isOnScreen(element)
{
    var curPos = element.offset();
    var curTop = curPos.top;
    var screenHeight = $(window).height();
    return (curTop > screenHeight) ? false : true;
}

And then call the function using something like:

if(isOnScreen($('#myDivId'))) { /* Code here... */ };

I see only two options:

1. You have memory leaks in your application.
2. Devices do not have enough memory when running your application.

It's simple with open source 7zip SFX-Packager - easy way to just "Drag & drop" folders onto it, and it creates a portable/self-extracting package.

You're looking for:

.is(':visible')

Although you should probably change your selector to use jQuery considering you're using it in other places anyway:

if($('#testElement').is(':visible')) {
    // Code
}

It is important to note that if any one of a target element's parent elements are hidden, then .is(':visible') on the child will return false (which makes sense).

jQuery 3

:visible has had a reputation for being quite a slow selector as it has to traverse up the DOM tree inspecting a bunch of elements. There's good news for jQuery 3, however, as this post explains (Ctrl + F for :visible):

Thanks to some detective work by Paul Irish at Google, we identified some cases where we could skip a bunch of extra work when custom selectors like :visible are used many times in the same document. That particular case is up to 17 times faster now!

Keep in mind that even with this improvement, selectors like :visible and :hidden can be expensive because they depend on the browser to determine whether elements are actually displaying on the page. That may require, in the worst case, a complete recalculation of CSS styles and page layout! While we don’t discourage their use in most cases, we recommend testing your pages to determine if these selectors are causing performance issues.

Expanding even further to your specific use case, there is a built in jQuery function called $.fadeToggle():

function toggleTestElement() {
    $('#testElement').fadeToggle('fast');
}

I would prefer AssertJ for this.

        assertThatExceptionOfType(ExpectedException.class)
        .isThrownBy(() -> {
            // method call
        }).withMessage("My message");

.container {overflow:auto;} will do the trick. If you want to control specific direction, you should set auto for that specific axis. A.E.

.container {overflow-y:auto;} .container {overflow-x:hidden;}

The above code will hide any overflow in the x-axis and generate a scroll-bar when needed on the y-axis.But you have to make sure that you content default height smaller than the container height; if not, the scroll-bar will not be hidden.

What do you mean by delete? In Python, removing a reference (or a name) can be done with the del keyword, but if there are other names to the same object that object will not be deleted.

--> test = 3
--> print(test)
3
--> del test
--> print(test)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'test' is not defined

compared to:

--> test = 5
--> other is test  # check that both name refer to the exact same object
True
--> del test       # gets rid of test, but the object is still referenced by other
--> print(other)
5

You can do that simple with Files.size(new File(filename).toPath()).

I think that the RoundingMode you are looking for is ROUND_HALF_EVEN. From the javadoc:

Rounding mode to round towards the "nearest neighbor" unless both neighbors are equidistant, in which case, round towards the even neighbor. Behaves as for ROUND_HALF_UP if the digit to the left of the discarded fraction is odd; behaves as for ROUND_HALF_DOWN if it's even. Note that this is the rounding mode that minimizes cumulative error when applied repeatedly over a sequence of calculations.

Here is a quick test case:

BigDecimal a = new BigDecimal("10.12345");
BigDecimal b = new BigDecimal("10.12556");

a = a.setScale(2, BigDecimal.ROUND_HALF_EVEN);
b = b.setScale(2, BigDecimal.ROUND_HALF_EVEN);

System.out.println(a);
System.out.println(b);

Correctly prints:

10.12
10.13

UPDATE:

setScale(int, int) has not been recommended since Java 1.5, when enums were first introduced, and was finally deprecated in Java 9. You should now use setScale(int, RoundingMode) e.g:

setScale(2, RoundingMode.HALF_EVEN)

Thanks for the answers. Now I know that there are two ways of "SAVE AS" in Vim.

Assumed that I'm editing hello.txt.

• :w world.txt will write hello.txt's content to the file world.txt while keeping hello.txt as the opened buffer in vim.
• :sav world.txt will first write hello.txt's content to the file world.txt, then close buffer hello.txt, finally open world.txt as the current buffer.

You have two options:

OPTION 1:

You can use removeProperty method. It will remove a style from an element.

el.style.removeProperty('zoom');

OPTION 2:

You can set it to the default value:

el.style.zoom = "";

The effective zoom will now be whatever follows from the definitions set in the stylesheets (through link and style tags). So this syntax will only modify the local style of this element.

There's a nice article which may answer your question /only it prints the paths instead of collecting them/. Please note that you can experiment with the C++/Python samples in the online IDE.

http://www.geeksforgeeks.org/find-paths-given-source-destination/

From the Javadoc:

Sometimes several tests need to share computationally expensive setup (like logging into a database). While this can compromise the independence of tests, sometimes it is a necessary optimization. Annotating a public static void no-arg method with @BeforeClass causes it to be run once before any of the test methods in the class. The @BeforeClass methods of superclasses will be run before those the current class.

I think the wait/notify/notifyAll methods don't belong on the Object class as it pollutes all objects with methods that are rarely used. They make much more sense on a dedicated Lock class. So from this point of view, perhaps it's better to use a tool that is explicitly designed for the job at hand - ie ReentrantLock.

Isn't the platform solution for this implementation to use a context menu that shows on a long press?

Is the question author aware of context menus? Stacking up buttons in a listview has performance implications, will clutter your UI and violate the recommended UI design for the platform.

On the flipside; context menus - by nature of not having a passive representation - are not obvious to the end user. Consider documenting the behaviour?

This guide should give you a good start.

I tried every solution above, but none of them worked for my problem. (I'm sure there are 1000 solutions to this problem) For my scenario, I was attempting to publish my WCF web service that I had in test into production.

However, I failed to realize that in production we are HTTPS only, meaning we redirect everything to HTTPS. As it turns out, I was pointing to the service via HTTP instead of HTTPS, thus causing the error. The solution in this scenario was to simply to change the address protocol to HTTPS rather than HTTP.

I hope that helps some poor soul out there trying to figure out this problem.

You could host password in a repository and then just hide the page behind hidden address, that is derived from that password. This is not a very secure way, but it is simple.

Demonstration

string management is an expensive process. keeping strings immutable allows repeated strings to be reused, rather than re-created.

If you want to use mod_rewrite for access control you can use condition like user agent, http referrer, remote addr etc.

Example

RewriteCond %{REMOTE_ADDR} !=*.*.*.* #you ip address
RewriteRule ^$ - [F]

Refrences:

• https://httpd.apache.org/docs/2.4/rewrite/access.html

To find name of files with path recursively containing the particular string use below command for UNIX:

find . | xargs grep "searched-string"

for Linux:

grep -r "searched-string" .

find a file on UNIX server

find . -type f -name file_name

find a file on LINUX server

find . -name file_name

In Ruby 2.5 you can now use Dir.children. It gets filenames as an array except for "." and ".."

Example:

Dir.children("testdir")   #=> ["config.h", "main.rb"]

http://ruby-doc.org/core-2.5.0/Dir.html#method-c-children

To check if a folder exists or not, you can simply use the exists() method:

// Create a File object representing the folder 'A/B'
def folder = new File( 'A/B' )

// If it doesn't exist
if( !folder.exists() ) {
  // Create all folders up-to and including B
  folder.mkdirs()
}

// Then, write to file.txt inside B
new File( folder, 'file.txt' ).withWriterAppend { w ->
  w << "Some text\n"
}

you should change the adb port with this command:

adb reverse tcp:8880 tcp:8880; adb reverse tcp:8081 tcp:8081; adb reverse tcp:8881 tcp:8881

I had the same problem. My project layout looked like

\---super
    \---thirdparty
        +---mod1-root
        |   +---mod1-linux32
        |   \---mod1-win32
        \---mod2-root
            +---mod2-linux32
            \---mod2-win32

In my case, I had a mistake in my pom.xmls at the modX-root-level. I had copied the mod1-root tree and named it mod2-root. I incorrectly thought I had updated all the pom.xmls appropriately; but in fact, mod2-root/pom.xml had the same group and artifact ids as mod1-root/pom.xml. After correcting mod2-root's pom.xml to have mod2-root specific maven coordinates my issue was resolved.

Best to do like below:

HKEY_CLASSES_ROOT\Directory\shell\BashHere
Enter Data: Bash Here

HKEY_CLASSES_ROOT\Directory\shell\BashHere\command
Enter Data: 

cmd.exe /c C:\cygwin\bin\bash.exe --login -c "cd '%1'; exec /bin/bash"

In some cases you should use:

req.path

This gives you the path, instead of the complete requested URL. For example, if you are only interested in which page the user requested and not all kinds of parameters the url:

/myurl.htm?allkinds&ofparameters=true

req.path will give you:

/myurl.html

if some one is using AppCompatEditText then you need to set inputType="textMultiLine" here is the code you can copy

   <androidx.appcompat.widget.AppCompatEditText

        android:id="@+id/etNote"
        android:minLines="6"
        android:singleLine="false"
        android:lines="8"
        android:scrollbars="vertical"
        android:background="@drawable/rounded_border"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="@dimen/_25sdp"
        android:layout_marginTop="32dp"
        android:layout_marginEnd="@dimen/_25sdp"
        android:autofillHints=""

        android:gravity="start|top"
        android:inputType="textMultiLine"
         />

I downloaded a different installer "SQL Server 2014 Express with Advanced Services" and found Instance Features in it. Thanks for Alberto Solano's answer, it was really helpful.

My first installer was "SQL Server 2014 Express". It installed only SQL Management Studio and tools without Instance features. After installation "SQL Server 2014 Express with Advanced Services" my LocalDB is now alive!!!

try this,

    String dateStr = "17-April-2011 19:20:23.707000000 ";
    Date dateForm = new SimpleDateFormat("dd-MMMM-yyyy HH:mm:ss").parse(dateStr);
    SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy");  

    String newDate = format.format(dateForm);  

    Calendar today = Calendar.getInstance();
    Date fromDate = format.parse(newDate);
    today.setTime(fromDate);
    today.add(Calendar.DAY_OF_YEAR, 1);
    Date toDate= new SimpleDateFormat("dd-MM-yyyy").parse(format.format(today.getTime()));

    Criteria crit = sessionFactory.getCurrentSession().createCriteria(Model.class);
    crit.add(Restrictions.ge("dateFieldName", fromDate));
    crit.add(Restrictions.le("dateFieldName", toDate));
    return crit.list();

I also have same problem and in my case I injected reducer properly but still I couldn't type in field. It turns out if you are using immutable you have to use redux-form/immutable.

import {reducer as formReducer} from 'redux-form/immutable';
const reducer = combineReducers{

    form: formReducer
}
import {Field, reduxForm} from 'redux-form/immutable';
/* your component */

Notice that your state should be like state->form otherwise you have to explicitly config the library also the name for state should be form. see this issue

Starting with:

houses <- read.table(text="Semi            1
Single          2
Row             3
Single          2
Apartment       4
Apartment       4
Row             3",col.names=c("HouseType","HouseTypeNo"))

... you can use

as.numeric(factor(houses$HouseType))

... to give a unique number for each house type. You can see the result here:

> houses2 <- data.frame(houses,as.numeric(factor(houses$HouseType)))
> houses2
  HouseType HouseTypeNo as.numeric.factor.houses.HouseType..
1      Semi           1                                    3
2    Single           2                                    4
3       Row           3                                    2
4    Single           2                                    4
5 Apartment           4                                    1
6 Apartment           4                                    1
7       Row           3                                    2

... so you end up with different numbers on the rows (because the factors are ordered alphabetically) but the same pattern.

(EDIT: the remaining text in this answer is actually redundant. It occurred to me to check and it turned out that read.table() had already made houses$HouseType into a factor when it was read into the dataframe in the first place).

However, you may well be better just to convert HouseType to a factor, which would give you all the same benefits as HouseTypeNo, but would be easier to interpret because the house types are named rather than numbered, e.g.:

> houses3 <- houses
> houses3$HouseType <- factor(houses3$HouseType)
> houses3
  HouseType HouseTypeNo
1      Semi           1
2    Single           2
3       Row           3
4    Single           2
5 Apartment           4
6 Apartment           4
7       Row           3
> levels(houses3$HouseType)
[1] "Apartment" "Row"       "Semi"      "Single"  

Here is email code I used in one of my databases. I just made variables for the person I wanted to send it to, CC, subject, and the body. Then you just use the DoCmd.SendObject command. I also set it to "True" after the body so you can edit the message before it automatically sends.

Public Function SendEmail2()

Dim varName As Variant          
Dim varCC As Variant            
Dim varSubject As Variant      
Dim varBody As Variant          

varName = "[email protected]"
varCC = "[email protected], [email protected]"
'separate each email by a ','

varSubject = "Hello"
'Email subject

varBody = "Let's get ice cream this week"

'Body of the email
DoCmd.SendObject , , , varName, varCC, , varSubject, varBody, True, False
'Send email command. The True after "varBody" allows user to edit email before sending.
'The False at the end will not send it as a Template File

End Function

You should use the preprocessor macro __LINE__ and __FILE__. They are predefined macros and part of the C/C++ standard. During preprocessing, they are replaced respectively by a constant string holding an integer representing the current line number and by the current file name.

Others preprocessor variables :

• __func__ : function name (this is part of C99, not all C++ compilers support it)
• __DATE__ : a string of form "Mmm dd yyyy"
• __TIME__ : a string of form "hh:mm:ss"

Your code will be :

if(!Logical)
  printf("Not logical value at line number %d in file %s\n", __LINE__, __FILE__);

Serializing data structures containing only numeric or boolean values is fairly straightforward. If you don't have much to serialize, you can write a method for your specific type.

For a Dictionary<int, List<int>> as you have specified, you can use Linq:

string MyDictionaryToJson(Dictionary<int, List<int>> dict)
{
    var entries = dict.Select(d =>
        string.Format("\"{0}\": [{1}]", d.Key, string.Join(",", d.Value)));
    return "{" + string.Join(",", entries) + "}";
}

But, if you are serializing several different classes, or more complex data structures, or especially if your data contains string values, you would be better off using a reputable JSON library that already knows how to handle things like escape characters and line breaks. Json.NET is a popular option.

Sometimes you can play with padding and margin top, add line-height, etc.

I do not believe there is a Win32 API to calculate the space consumed by a directory, although I stand to be corrected on this. If there were then I would assume Explorer would use it. If you get the Properties of a large directory in Explorer, the time it takes to give you the folder size is proportional to the number of files/sub-directories it contains.

Your routine seems fairly neat & simple. Bear in mind that you are calculating the sum of the file lengths, not the actual space consumed on the disk. Space consumed by wasted space at the end of clusters, file streams etc, are being ignored.

I just tested and for me, none of the other solutions worked. I simply tried this and it worked perfectly on Firefox and Chrome, just as I had expected:

and the css:

.wrap {
    width: 640px;
    height: 480px;
    overflow: hidden;
}

iframe {
    width: 76.92% !important;
    height: 76.92% !important;
    -webkit-transform: scale(1.3);
    transform: scale(1.3);
    -webkit-transform-origin: 0 0;
    transform-origin: 0 0;
}

This scales all the content by 30%. The width/height percentages of course need to be adjusted accordingly (1/scale_factor).

Your markup:

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

The CSS:

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

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

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

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

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

In his excellent answer, StuartLC cites an answer to a related question and mentions that placing newlines inside the {expression} of an interpolated string "looks odd." Most would agree, but the unpleasant source code effect can be mitigated somewhat--and without any runtime consequences--by using dedicated {expression} blocks which resolve to default(String), that is, null (and specifically not String.Empty).

The (albeit minor) point is to not mess-up or pollute your actual expression content, by instead using a dedicated token for this purpose. So if you declare a constant, for example:

const String more = null;

...then a line which might be too long to look at in source code, such as...

var s1 = $"one: {99 + 1} two: {99 + 2} three: {99 + 3} four: {99 + 4} five: {99 + 5} six: {99 + 6}";

...can be instead written like this.

var s2 = $@"{more
    }one: {99 + 1} {more
    }two: {99 + 2} {more
    }three: {99 + 3} {more
    }four: {99 + 4} {more
    }five: {99 + 5} {more
    }six: {99 + 6}";

Or perhaps you prefer a different "odd" approach to the same thing:

// elsewhere:
public const String ? = null;  // Unicode '\u039E', Greek 'Capital Letter Xi'

// anywhere:
var s3 = $@"{
           ?}one: {99 + 1} {
           ?}two: {99 + 2} {
           ?}three: {99 + 3} {
           ?}four: {99 + 4} {
           ?}five: {99 + 5} {
           ?}six: {99 + 6}";

Actually, it looks like we can also do it without a continuation symbol:

var s4 = $@"one: {99 + 1
            }two: {99 + 2
            }three: {99 + 3
            }four: {99 + 4
            }five: {99 + 5
            }six: {99 + 6}";

All four examples produce the same string at runtime, which in this case is all on a single line:

one: 100 two: 101 three: 102 four: 103 five: 104 six: 105

As Stuart suggested, IL performance is preserved in both these examples by not using + to concatenate strings. Although the longer format string in my new example is indeed stored in the IL, and thus your executable, the null placeholders it references are not initialized, and there are no excess concatenations or function calls at runtime. For comparison, here is the IL for the above two examples.

IL for first example

ldstr "one: {0} two: {1} three: {2} four: {3} five: {4} six: {5}"
ldc.i4.6
newarr object
dup
ldc.i4.0
ldc.i4.s 100
box int32
stelem.ref
dup
ldc.i4.1
ldc.i4.s 101
box int32
stelem.ref
dup
ldc.i4.2
ldc.i4.s 102
box int32
stelem.ref
dup
ldc.i4.3
ldc.i4.s 103
box int32
stelem.ref
dup
ldc.i4.4
ldc.i4.s 104
box int32
stelem.ref
dup
ldc.i4.5
ldc.i4.s 105
box int32
stelem.ref
call string string::Format(string, object[])

IL for second example

ldstr "{0}one: {1} {2}two: {3} {4}three: {5} {6}four: {7} {8}five: {9} {10}six: {11}"
ldc.i4.s 12
newarr object
dup
ldc.i4.1
ldc.i4.s 100
box int32
stelem.ref
dup
ldc.i4.3
ldc.i4.s 101
box int32
stelem.ref
dup
ldc.i4.5
ldc.i4.s 102
box int32
stelem.ref
dup
ldc.i4.7
ldc.i4.s 103
box int32
stelem.ref
dup
ldc.i4.s 9
ldc.i4.s 104
box int32
stelem.ref
dup
ldc.i4.s 11
ldc.i4.s 105
box int32
stelem.ref
call string string::Format(string, object[])

Surprisingly no one told about this, which provides some !clarity:

style={{
backgroundColor: 'white',
opacity: 0.7
}}

On SQL Server? and on the same database server? Use three part naming.

INSERT INTO bar..tblFoobar( *fieldlist* )
SELECT *fieldlist* FROM foo..tblFoobar

This just moves the data. If you want to move the table definition (and other attributes such as permissions and indexes), you'll have to do something else.

Here is a totally different approach that works surprisingly well to change the font sizes:

Change the figure size!

I usually use code like this:

import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure(figsize=(4,3))
ax = fig.add_subplot(111)
x = np.linspace(0,6.28,21)
ax.plot(x, np.sin(x), '-^', label="1 Hz")
ax.set_title("Oscillator Output")
ax.set_xlabel("Time (s)")
ax.set_ylabel("Output (V)")
ax.grid(True)
ax.legend(loc=1)
fig.savefig('Basic.png', dpi=300)

The smaller you make the figure size, the larger the font is relative to the plot. This also upscales the markers. Note I also set the dpi or dot per inch. I learned this from a posting the AMTA (American Modeling Teacher of America) forum. Example from above code:

Look at following demo code.

Here is your XML file for UI,

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/btnCapture"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Camera" />

</LinearLayout>

And here is your Java class file,

public class CameraDemoActivity extends Activity {
    int TAKE_PHOTO_CODE = 0;
    public static int count = 0;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // Here, we are making a folder named picFolder to store
        // pics taken by the camera using this application.
        final String dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/picFolder/";
        File newdir = new File(dir);
        newdir.mkdirs();

        Button capture = (Button) findViewById(R.id.btnCapture);
        capture.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {

                // Here, the counter will be incremented each time, and the
                // picture taken by camera will be stored as 1.jpg,2.jpg
                // and likewise.
                count++;
                String file = dir+count+".jpg";
                File newfile = new File(file);
                try {
                    newfile.createNewFile();
                }
                catch (IOException e)
                {
                }

                Uri outputFileUri = Uri.fromFile(newfile);

                Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);

                startActivityForResult(cameraIntent, TAKE_PHOTO_CODE);
            }
        });
    }

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

        if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) {
            Log.d("CameraDemo", "Pic saved");
        }
    }
}

Note:

Specify the following permissions in your manifest file,

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

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