I am mostly posting this in case someone comes along and is not aware that VB2005 and VB2008 have update utilities that convert older VB versions to it's format. Especially since no one bothered to point that fact out.

Points taken, but maintenance of this VB6 product is unavoidable. It would also be costly in man-hours to replace the Sheridan controls with native ones. Simply developing on a 32-bit machine would be a better alternative than doing that. I would like to install everything on Win7 64-bit ideally. – CJ7

Have you tried utilizing the code upgrade functionality of VB Express 2005+?

If not, 1. Make a copy of your code - folder and all. 2. Import the project into VB express 2005. This will activate the update wizard. 3. Debug and get the app running. 4. Create a new installer utilizing MS free tool. 5. You now have a 32 bit application with a 32 bit installer.

Until you do this, you will never know how difficult or hard it will be to update and modernize the program. It is quite possible that the wizard will update the Sheridan controls to the VB 2005 controls. Again, you will not know if it does and how well it does it until you try it.

Alternatively, stick with the 32 Bit versions of Windows 7 and 8. I have Windows 7 x64 and a program that will not run. However, the program will run in Windows 7 32 bit as well as Windows 8 RC 32 bit. Under Windows 8 RC 32, I was prompted to enable 16 bit emulation which I did and the program rand quite fine afterwords.

print type(variable_name)

I also highly recommend the IPython interactive interpreter when dealing with questions like this. It lets you type variable_name? and will return a whole list of information about the object including the type and the doc string for the type.

e.g.

In [9]: var = 123

In [10]: var?
Type:       int
Base Class: <type 'int'>
String Form:    123
Namespace:  Interactive
Docstring:
    int(x[, base]) -> integer

Convert a string or number to an integer, if possible. A floating point argument will be truncated towards zero (this does not include a string representation of a floating point number!) When converting a string, use the optional base. It is an error to supply a base when converting a non-string. If the argument is outside the integer range a long object will be returned instead.

Use this function:

function getScriptName()
{
    $filename = baseName($_SERVER['REQUEST_URI']);
    $ipos = strpos($filename, "?");
    if ( !($ipos === false) )   $filename = substr($filename, 0, $ipos);
    return $filename;
}

I used the Visual Studio 2008 Uninstall tool and it worked fine for me.

You can use this tool to uninstall Visual Studio 2008 official release and Visual Studio 2008 Release candidate (Only English version).

Found here, on the MSDN Forum: MSDN forum topic.

I found this answer here

Be sure you run the tool with admin-rights.

You are more vulnerable to attacks if using eval: JSON is a subset of Javascript and json.parse just parses JSON whereas eval would leave the door open to all JS expressions.

DateTime inherits its equals method from AbstractInstant. It is implemented as such

public boolean equals(Object readableInstant) {     // must be to fulfil ReadableInstant contract     if (this == readableInstant) {         return true;     }     if (readableInstant instanceof ReadableInstant == false) {         return false;     }     ReadableInstant otherInstant = (ReadableInstant) readableInstant;     return         getMillis() == otherInstant.getMillis() &&         FieldUtils.equals(getChronology(), otherInstant.getChronology()); } 

Notice the last line comparing chronology. It's possible your instances' chronologies are different.

Expanding on the great answers by KingCrunch and VonC

I combined them both:

git clone --mirror [email protected]/reponame reponame.git
cd reponame.git
git bundle create reponame.bundle --all

After that you have a file called reponame.bundle that can be easily copied around. You can then create a new normal git repository from that using git clone reponame.bundle reponame.

Note that git bundle only copies commits that lead to some reference (branch or tag) in the repository. So tangling commits are not stored to the bundle.

Double quote (" ") the entire URL .It works.

curl "http://www.mysite.com?name=john&passwd=@31&3*J"

Those two replaceAll calls will always produce the same result, regardless of what x is. However, it is important to note that the two regular expressions are not the same:

• \\s - matches single whitespace character
• \\s+ - matches sequence of one or more whitespace characters.

In this case, it makes no difference, since you are replacing everything with an empty string (although it would be better to use \\s+ from an efficiency point of view). If you were replacing with a non-empty string, the two would behave differently.

For example:

String myInput = null;
Scanner myscan = new Scanner(System.in).useDelimiter("\\n");
System.out.println("Enter your input: ");
myInput = myscan.next();
System.out.println(myInput);

This will let you use Enter as a delimiter.

Thus, if you input:

Hello world (ENTER)

it will print 'Hello World'.

I believe because cases must be constant values, the switch statement does the equivelent of a goto, so based on the value of the variable it jumps to the right case, whereas in the if/then statement it must evaluate each expression.

After insuring that the string "strOutput" has a correct XML structure, you can do this:

Matcher junkMatcher = (Pattern.compile("^([\\W]+)<")).matcher(strOutput);
strOutput = junkMatcher.replaceFirst("<");

Based on your comments to orip's post, I guess this is what happened:

1. You edited __init__.py on windows.
2. The windows editor added something non-printing, perhaps a carriage-return (end-of-line in Windows is CR/LF; in unix it is LF only), or perhaps a CTRL-Z (windows end-of-file).
3. You used WinSCP to copy the file to your unix box.
4. WinSCP thought: "This has something that's not basic text; I'll put a .bin extension to indicate binary data."
5. The missing __init__.py (now called __init__.py.bin) means python doesn't understand toolkit as a package.
6. You create __init__.py in the appropriate directory and everything works... ?

It happens also when you have two views in two fragments with the same ids

Try the following:

foo(*values)

This can be found in the Python docs as Unpacking Argument Lists.

$('#userZipFiles option').prop('selected', function() {
        return this.defaultSelected;
    });     

I work for a large corporation and encountered this same error, but needed a different work around. My issue was related to proxy settings. I had my proxy set up so I needed to set my no_proxy to whitelist AWS before I was able to get everything to work. You can set it in your bash script as well if you don't want to muddy up your Python code with os settings.

Python:

import os
os.environ["NO_PROXY"] = "s3.amazonaws.com"

Bash:

export no_proxy = "s3.amazonaws.com"

Edit: The above assume a US East S3 region. For other regions: use s3.[region].amazonaws.com where region is something like us-east-1 or us-west-2

It's working for me :

What you should do is create a service to share data between controllers.

Nice tutorial https://www.youtube.com/watch?v=HXpHV5gWgyk

Well the code you've shown doesn't actually include adding any Integers to the ArrayList - but if you do know that you've got integers, you can use:

sum = (double) ((Integer) marks.get(i)).intValue();

That will convert it to an int, which can then be converted to double. You can't just cast directly between the boxed classes.

Note that if you can possibly use generics for your ArrayList, your code will be clearer.

List is an Interface . You cant use List to initialize it.

  List<String> supplierNames = new ArrayList<String>();

These are the some of List impelemented classes,

ArrayList, LinkedList, Vector

You could use any of this as per your requirement. These each classes have its own features.

It looks to me as though the basic problem is that you have one wait() call rather than a loop that waits until there are no more children. You also only wait if the last fork() is successful rather than if at least one fork() is successful.

You should only use _exit() if you don't want normal cleanup operations - such as flushing open file streams including stdout. There are occasions to use _exit(); this is not one of them. (In this example, you could also, of course, simply have the children return instead of calling exit() directly because returning from main() is equivalent to exiting with the returned status. However, most often you would be doing the forking and so on in a function other than main(), and then exit() is often appropriate.)

Hacked, simplified version of your code that gives the diagnostics I'd want. Note that your for loop skipped the first element of the array (mine doesn't).

#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
#include <sys/wait.h>

int main(void)
{
    pid_t child_pid, wpid;
    int status = 0;
    int i;
    int a[3] = {1, 2, 1};

    printf("parent_pid = %d\n", getpid());
    for (i = 0; i < 3; i++)
    {
        printf("i = %d\n", i);
        if ((child_pid = fork()) == 0)
        {
            printf("In child process (pid = %d)\n", getpid());
            if (a[i] < 2)
            {
                printf("Should be accept\n");
                exit(1);
            }
            else
            {
                printf("Should be reject\n");
                exit(0);
            }
            /*NOTREACHED*/
        }
    }

    while ((wpid = wait(&status)) > 0)
    {
        printf("Exit status of %d was %d (%s)\n", (int)wpid, status,
               (status > 0) ? "accept" : "reject");
    }
    return 0;
}

Example output (MacOS X 10.6.3):

parent_pid = 15820
i = 0
i = 1
In child process (pid = 15821)
Should be accept
i = 2
In child process (pid = 15822)
Should be reject
In child process (pid = 15823)
Should be accept
Exit status of 15823 was 256 (accept)
Exit status of 15822 was 0 (reject)
Exit status of 15821 was 256 (accept)

Have you tried the following:

$('#theDiv').prepend('<img id="theImg" src="theImg.png" />')

No need to extract the month and year.Just need to use the unix_timestamp(date String,format String) function.

For Example:

select yourdate_column
from your_table
where unix_timestamp(yourdate_column, 'yyyy-MM-dd') >= unix_timestamp('2014-06-02', 'yyyy-MM-dd')
and unix_timestamp(yourdate_column, 'yyyy-MM-dd') <= unix_timestamp('2014-07-02','yyyy-MM-dd')
order by yourdate_column limit 10; 

((portion/total) * 100).toFixed(2) + '%'

document.body is not yet available when your code runs.

What you can do instead:

var docBody=document.getElementsByTagName("body")[0];
docBody.appendChild(mySpan);

Only call time pass-by-reference is removed. So change:

call_user_func($func, &$this, &$client ...

To this:

call_user_func($func, $this, $client ...

&$this should never be needed after PHP4 anyway period.

If you absolutely need $client to be passed by reference, update the function ($func) signature instead (function func(&$client) {)

I suggest qTip.

To create a signature, I must use my secret key. But all things happens on a client side, so, the secret key can be easily revealed from page source (even if I obfuscate/encrypt my sources).

This is where you have misunderstood. The very reason digital signatures are used is so that you can verify something as correct without revealing your secret key. In this case the digital signature is used to prevent the user from modifying the policy you set for the form post.

Digital signatures such as the one here are used for security all around the web. If someone (NSA?) really were able to break them, they would have much bigger targets than your S3 bucket :)

The only thing about using telnet to test postfix, or other SMTP, is that you have to know the commands and syntax. Instead, just use swaks :)

It's just one easy command.

Even I had the same problem understanding how are CPython, JPython, IronPython, PyPy are different from each other.

So, I am willing to clear three things before I begin to explain:

1. Python: It is a language, it only states/describes how to convey/express yourself to the interpreter (the program which accepts your python code).
2. Implementation: It is all about how the interpreter was written, specifically, in what language and what it ends up doing.
3. Bytecode: It is the code that is processed by a program, usually referred to as a virtual machine, rather than by the "real" computer machine, the hardware processor.

CPython is the implementation, which was written in C language. It ends up producing bytecode (stack-machine based instruction set) which is Python specific and then executes it. The reason to convert Python code to a bytecode is because it's easier to implement an interpreter if it looks like machine instructions. But, it isn't necessary to produce some bytecode prior to execution of the Python code (but CPython does produce).

If you want to look at CPython's bytecode then you can. Here's how you can:

>>> def f(x, y):                # line 1
...    print("Hello")           # line 2
...    if x:                    # line 3
...       y += x                # line 4
...    print(x, y)              # line 5
...    return x+y               # line 6
...                             # line 7
>>> import dis                  # line 8
>>> dis.dis(f)                  # line 9

36 RETURN_VALUE

Now, let's have a look at the above code. Lines 1 to 6 are a function definition. In line 8, we import the 'dis' module which can be used to view the intermediate Python bytecode (or you can say, disassembler for Python bytecode) that is generated by CPython (interpreter).

NOTE: I got the link to this code from #python IRC channel: https://gist.github.com/nedbat/e89fa710db0edfb9057dc8d18d979f9c

And then, there is Jython, which is written in Java and ends up producing Java byte code. The Java byte code runs on Java Runtime Environment, which is an implementation of Java Virtual Machine (JVM). If this is confusing then I suspect that you have no clue how Java works. In layman terms, Java (the language, not the compiler) code is taken by the Java compiler and outputs a file (which is Java byte code) that can be run only using a JRE. This is done so that, once the Java code is compiled then it can be ported to other machines in Java byte code format, which can be only run by JRE. If this is still confusing then you may want to have a look at this web page.

Here, you may ask if the CPython's bytecode is portable like Jython, I suspect not. The bytecode produced in CPython implementation was specific to that interpreter for making it easy for further execution of code (I also suspect that, such intermediate bytecode production, just for the ease the of processing is done in many other interpreters).

So, in Jython, when you compile your Python code, you end up with Java byte code, which can be run on a JVM.

Similarly, IronPython (written in C# language) compiles down your Python code to Common Language Runtime (CLR), which is a similar technology as compared to JVM, developed by Microsoft.

$user = User::where('email', '=', Input::get('email'))->first();
if ($user === null) {
   // user doesn't exist
}

can be written as

if (User::where('email', '=', Input::get('email'))->first() === null) {
   // user doesn't exist
}

This will return true or false without assigning a temporary variable if that is all you are using $user for in the original statement.

A very common problem and I have used google collections and here is my code

public class FindByIdPredicate implements Predicate<IDObject> {

private Long entityId;

public FindByIdPredicate(final Long entityId) {
    this.entityId = entityId;

}

@Override
public boolean apply(final IDObject input) {
    return input.getId().equals(this.entityId);
}

/**
     * Pass in the Collection
 * @param Collection
 * @return IdObject if present or null
 */
public IDObject getEntity(final Collection<? extends IDObject> collection) {

    for (IDObject idObject : collection) {
        if (this.apply(idObject)) {
            return idObject;
        }
    }
    return null;

}

/**
 * @param Set
 * @return IdObject if present or null
 */
@SuppressWarnings("unchecked")
public <T> T getEntity(final Set<? extends IDObject> set) {

    for (IDObject idObject : set) {
        if (this.apply(idObject)) {
            return (T) idObject;
        }
    }
    return null;

}

}

Hope this helps

Here is the solution I found:

How to fix the missing MSVCR711.dll problem

You can find MSVCR71.dll file in following location of your installed SQL Developer 2.1 directory:

sqldeveloper-2.1.0.63.10\sqldeveloper\jdk\jre\bin\MSVCR71.dll

Run the following commands from git CLI:

# move to the wanted commit
git reset --hard <commit-hash> 

# update remote
git push --force origin <branch-name> 

The error is due to rvm is not running as in login shell. Hence try the below command:

/bin/bash --login

You will able run rvm commands instantly as login shell in terminal.

Thanks!

My use case: just tried popping onto the wrong branch and got conflicts. All I need is to undo the pop but keep it in the stash list so I can pop it out on the correct branch. I did this:

git reset HEAD --hard
git checkout my_correct_branch
git stash pop

Easy.

What if you set the timezone of the role you are using?

ALTER ROLE my_db_user IN DATABASE my_database
    SET "TimeZone" TO 'UTC';

Will this be of any use?

I had the same problem but the issue was a different one, I was trying to create a service and pass $scope to it as a parameter.
That's another way to get this error as the documentation of that link says:

Attempting to inject a scope object into anything that's not a controller or a directive, for example a service, will also throw an Unknown provider: $scopeProvider <- $scope error. This might happen if one mistakenly registers a controller as a service, ex.:

angular.module('myModule', [])
       .service('MyController', ['$scope', function($scope) {
        // This controller throws an unknown provider error because
        // a scope object cannot be injected into a service.
}]);

If you are calling from within Stored Procedure don't use @. In my case it returns 0

CALL SP_NAME(L_OUTPUT_PARAM)

If your string is empty,

DECLARE @String VARCHAR(100)
SET @String = ''
SELECT LEFT(@String, LEN(@String) - 1)

then this code will cause error message 'Invalid length parameter passed to the substring function.'

You can handle it this way:

SELECT LEFT(@String, NULLIF(LEN(@String)-1,-1))

It will always return result, and NULL in case of empty string.

You can also use events to trigger the Popdown.

Here's a fiddle based on satchmorun's solution. It dispenses with the PopdownAPI, and the top-level controller instead $broadcasts 'success' and 'error' events down the scope chain:

$scope.success = function(msg) { $scope.$broadcast('success', msg); };
$scope.error   = function(msg) { $scope.$broadcast('error', msg); };

The Popdown module then registers handler functions for these events, e.g:

$scope.$on('success', function(event, msg) {
    $scope.status = 'success';
    $scope.message = msg;
    $scope.toggleDisplay();
});

This works, at least, and seems to me to be a nicely decoupled solution. I'll let others chime in if this is considered poor practice for some reason.

From Xcode v4.3, it is being installed as application. The simulator is available at

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iOS\ Simulator.app/

For HttpClient-4.1 using TLSv1.2, code would go something like this:

        SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
        sslContext.init(null, null, new SecureRandom());
        SSLSocketFactory sf = new SSLSocketFactory(sslContext);
        Scheme httpsScheme = new Scheme("https", 443, sf);
        SchemeRegistry schemeRegistry = new SchemeRegistry();
        schemeRegistry.register(httpsScheme);
        ClientConnectionManager cm =  new        SingleClientConnManager(schemeRegistry);
        HttpClient client = new DefaultHttpClient(cm);

       // Use client to make the connection and get the results.

Old question, but thought I'd share my solution anyway. Pretty simple.

dicta_set = set(dicta.items()) # creates a set of tuples (k/v pairs)
dictb_set = set(dictb.items())
setdiff = dictb_set.difference(dicta_set) # any set method you want for comparisons
for k, v in setdiff: # unpack the tuples for processing
    print(f"k/v differences = {k}: {v}")

This code creates two sets of tuples representing the k/v pairs. It then uses a set method of your choosing to compare the tuples. Lastly, it unpacks the tuples (k/v pairs) for processing.

It is from an external js file and it is the only file linked to the page.

OK.

When I double click this file I get the following error

Sounds like you're double-clicking/running a .js file, which will attempt to run the script outside the browser, like a command line script. And that would explain this error:

Windows Script Host Error: 'window' is not defined Code: 800A1391

... not an error you'll see in a browser. And of course, the browser is what supplies the window object.

ADDENDUM: As a course of action, I'd suggest opening the relevant HTML file and taking a peek at the console. If you don't see anything there, it's likely your window.onload definition is simply being hit after the browser fires the window.onload event.

You have not defined the variable input_line.

Add this:

string input_line;

And add this include.

#include <string>

Here is the full example. I also removed the semi-colon after the while loop, and you should have getline inside the while to properly detect the end of the stream.

#include <iostream>
#include <string>

int main() {
    for (std::string line; std::getline(std::cin, line);) {
        std::cout << line << std::endl;
    }
    return 0;
}

In my case the problem was that Xcode was not installed.

How to install java packages:

Install desired java version / versions using official ubuntu packages, which are managed using alternatives:
sudo apt install -y openjdk-8-jdk
or/and other version: sudo apt install -y openjdk-11-jdk

Above answers are correct only when you have only one version for all software on your machine, and you can skip using update-alternatives. So one can quickly hardcode it in .bashrc or some other place:
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64
but it's not healthy, as later on you may change the version.

Correct way to set JAVA_HOME (and optionally JAVA_SDK, JAVA_JRE )

The correct way (and mandatory when you have more than one), is to detect what update-alternative is pointing to, and always use update-alternatives to switch active version.

Here are the suggestions for both: only specific unix account or for all accounts (machine level).

1. for a specific unix account only:

Use this if you don't have permissions to do it at machine level.

cat <<'EOF' >>~/.bashrc

export JAVA_HOME=$(update-alternatives --query java | grep Value | cut -d" " -f2 | sed 's!\(\/.*\)jre\(.*\)!\1!g')
export JDK_HOME=${JAVA_HOME}
export JRE_HOME=${JDK_HOME}/jre/

EOF

2. To do it at machine level, and for all bourne shells, you need 2 steps:

2.a

cat <<'EOF' | sudo tee /etc/profile.d/java_home_env.sh >/dev/null

export JAVA_HOME=$(update-alternatives --query java | grep Value | cut -d" " -f2 | sed 's!\(\/.*\)jre\(.*\)!\1!g')
export JDK_HOME=${JAVA_HOME}
export JRE_HOME=${JDK_HOME}/jre/

EOF

As your shell might not be set as interactive by default, you may want to do this also:
2.b

cat <<'EOF' | sudo tee -a /etc/bash.bashrc >/dev/null
if [ -d /etc/profile.d ]; then
  for i in /etc/profile.d/*.sh; do
    if [ -r $i ]; then
      . $i
    fi
  done
  unset i
fi
EOF

PS: There should be no need to update the $PATH, as update-alternatives takes care of the link to /usr/bin/.
More on: https://manpages.ubuntu.com/manpages/trusty/man8/update-alternatives.8.html

In /etc/apache2/ports.conf, change the port as

Listen 8079

Then go to /etc/apache2/sites-enabled/000-default.conf

And change the first line as

<VirtualHost *: 8079>

Now restart

sudo service apache2 restart

Apache will now listen on port 8079 and redirect to /var/www/html

I tend to just show/hide a IMG as other have stated. I found a good website which generates "loading gifs"

Link I just put it inside a div and hide by default display: none; (css) then when you call the function show the image, once its complete hide it again.

Fix:

I chose the "ISAPI & CGI Restrictions" after clicking the server name (not the site name) in IIS Manager, and right clicked the "ASP.NET v4.0.30319" lines and chose "Allow".

After turning on ASP.NET from "Programs and Features > Turn Windows features on or off", you must install ASP.NET from the Windows command prompt. The MIME types don't ever show up, but after doing this command, I noticed these extensions showed up under the IIS web site "Handler Mappings" section of IIS Manager.

However, I still got this error. But if you do what I mentioned for the "Fix", this will go away.

HTTP Error 404.2 - Not Found
The page you are requesting cannot be served because of the ISAPI and CGI Restriction list settings on the Web server.

Yes include the first file into the second. That's all.

See an example below,

File1.php :

<?php
  function first($int, $string){ //function parameters, two variables.
    return $string;  //returns the second argument passed into the function
  }
?>

Now Using include (http://php.net/include) to include the File1.php to make its content available for use in the second file:

File2.php :

<?php
  include 'File1.php';
  echo first(1,"omg lol"); //returns omg lol;
?>

My big issue here was to build the Object structure required to match RestTemplate to a compatible Class. Luckily I found http://www.jsonschema2pojo.org/ (get the JSON response in a browser and use it as input) and I can't recommend this enough!

I'm using git version 2.19.2.windows.1.

the only thing that worked for me was to remove the .git/rebase-apply/ directory and do a git reset --hard.

On Windows 10 you can find out the path by going to Control Panel > Programs > Java. In the panel that shows up, you can find the path as demonstrated in the screenshot below. In the Java Control Panel, go to the 'Java' tab and then click the 'View' button under the description 'View and manage Java Runtime versions and settings for Java applications and applets.'

This should work on Windows 7 and possibly other recent versions of Windows.

public class OneWayFragment extends Fragment {

    ImageView img_search;


public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {


        View view = inflater.inflate(R.layout.one_way_fragment, container, false);
        img_search = (ImageView) view.findViewById(R.id.search);


        img_search.setOnClickListener(new View.OnClickListener() {
            @Override`enter code here`
            public void onClick(View v) {
                Intent displayFlights = new Intent(getActivity(), SelectFlight.class);
                startActivity(displayFlights);
            }
        });

Why not just use the $_POST['submit'] variable as a logical statement in order to save whatever is in the form. You can always redirect to the same page (In case they refresh, and when they hit go back in the browser, the submit post variable wouldn't be set anymore. Just make sure your submit button has a name and id of submit.

REST vs. SOAP

SOAP:

? SOAP is simple object access protocol that run on TCP/UDP/SMTP.
? SOAP read and write request response messages in XML format.
? SOAP uses interface in order to define the services.
? SOAP is more secure as it has its own security and well defined standards.
? SOAP follows RPC and Document style to define web services.
? SOAP uses SOAP-UI as client tools for testing.

REST

? REST is representational state transfer that uses underlying HTTP protocols.
? REST is stateless.
? REST is an architectural style that is used to describe and define web services.
? REST can read and write request response messages in JSON/XML/Plain HTML.
? REST uses URI for each resource that is used in web service.A resource can be image text method etc.
? REST uses set of verbs, like HTTP's GET, POST, PUT, DELETE.
? REST is easy to develop and easy to manage as compared to SOAP UI.
? REST has light-weight client tools or plugins that can easily be integrated inside a browser.
? REST services are cacheable.

Pawel Sawicz .NET blog has a real good explanation and example code, explaining how to call the library;

GET:

var client = new RestClient("192.168.0.1");
var request = new RestRequest("api/item/", Method.GET);
var queryResult = client.Execute<List<Items>>(request).Data;

POST:

var client = new RestClient("http://192.168.0.1");
var request = new RestRequest("api/item/", Method.POST);
request.RequestFormat = DataFormat.Json;
request.AddBody(new Item
{
   ItemName = someName,
   Price = 19.99
});
client.Execute(request);

DELETE:

var item = new Item(){//body};
var client = new RestClient("http://192.168.0.1");
var request = new RestRequest("api/item/{id}", Method.DELETE);
request.AddParameter("id", idItem);
 
client.Execute(request)

The RestSharp GitHub page has quite an exhaustive sample halfway down the page. To get started install the RestSharp NuGet package in your project, then include the necessary namespace references in your code, then above code should work (possibly negating your need for a full example application).

Anything that is not stored on an EBS volume that is mounted to the instance will be lost.

For example, if you mount your EBS volume at /mystuff, then anything not in /mystuff will be lost. If you don't mount an ebs volume and save stuff on it, then I believe everything will be lost.

You can create an AMI from your current machine state, which will contain everything in your ephemeral storage. Then, when you launch a new instance based on that AMI it will contain everything as it is now.

Update: to clarify based on comments by mattgmg1990 and glenn bech:

Note that there is a difference between "stop" and "terminate". If you "stop" an instance that is backed by EBS then the information on the root volume will still be in the same state when you "start" the machine again. According to the documentation, "By default, the root device volume and the other Amazon EBS volumes attached when you launch an Amazon EBS-backed instance are automatically deleted when the instance terminates" but you can modify that via configuration.

Make a pool of all ajax request and abort them.....

var xhrQueue = []; 

$(document).ajaxSend(function(event,jqxhr,settings){
    xhrQueue.push(jqxhr); //alert(settings.url);
});

$(document).ajaxComplete(function(event,jqxhr,settings){
    var i;   
    if((i=$.inArray(jqxhr,xhrQueue)) > -1){
        xhrQueue.splice(i,1); //alert("C:"+settings.url);
    }
});

ajaxAbort = function (){  //alert("abortStart");
    var i=0;
    while(xhrQueue.length){ 
        xhrQueue[i++] .abort(); //alert(i+":"+xhrQueue[i++]);
    }
};

It is kind of late, but I looked for e similar filter and ended using something like this:

<div ng-controller="TestCtrl">
 <div ng-repeat="(k,v) in items | filter:{secId: '!!'}">
   {{k}} {{v.pos}}
 </div>
</div>

In my case, I was using React.ReactNode as a type for a functional component instead of React.FC type.

In this component to be exact:

export const PropertiesList: React.FC = (props: any) => {_x000D_
  const list:string[] = [_x000D_
    ' Consequat Phasellus sollicitudin.',_x000D_
    ' Consequat Phasellus sollicitudin.',_x000D_
    '...'_x000D_
  ]_x000D_
_x000D_
  return (_x000D_
    <List_x000D_
      header={<ListHeader heading="Properties List" />}_x000D_
      dataSource={list}_x000D_
        renderItem={(listItem, index) =>_x000D_
          <List.Item key={index}> {listItem } </List.Item>_x000D_
      }_x000D_
    />_x000D_
  )_x000D_
}

For me save_queries option was turned off so,

$this->db->save_queries = TRUE; //Turn ON save_queries for temporary use.
$str = $this->db->last_query();
echo $str;

Ref: Can't get result from $this->db->last_query(); codeigniter

I really like Marc's solution, but I think it can be slightly improved to avoid using a "magic string" (which doesn't support refactoring). Instead of using the property name as a string, it's easy to make it a lambda expression :

private string name;
public string Name
{
    get { return name; }
    set { SetField(ref name, value, () => Name); }
}

Just add the following methods to Marc's code, it will do the trick :

protected virtual void OnPropertyChanged<T>(Expression<Func<T>> selectorExpression)
{
    if (selectorExpression == null)
        throw new ArgumentNullException("selectorExpression");
    MemberExpression body = selectorExpression.Body as MemberExpression;
    if (body == null)
        throw new ArgumentException("The body must be a member expression");
    OnPropertyChanged(body.Member.Name);
}

protected bool SetField<T>(ref T field, T value, Expression<Func<T>> selectorExpression)
{
    if (EqualityComparer<T>.Default.Equals(field, value)) return false;
    field = value;
    OnPropertyChanged(selectorExpression);
    return true;
}

BTW, this was inspired by this blog post updated URL

Like Babel says in the docs, for Babel > 7.4.0 the module @babel/polyfill is deprecated, so it's recommended to use directly core-js and regenerator-runtime libraries that before were included in @babel/polyfill.

So this worked for me:

npm install --save [email protected]
npm install regenerator-runtime

then add to the very top of your initial js file:

import 'core-js/stable';
import 'regenerator-runtime/runtime';

This --> is not an operator at all. We have an operator like ->, but not like -->. It is just a wrong interpretation of while(x-- >0) which simply means x has the post decrement operator and this loop will run till it is greater than zero.

Another simple way of writing this code would be while(x--). The while loop will stop whenever it gets a false condition and here there is only one case, i.e., 0. So it will stop when the x value is decremented to zero.

you didn't import sys in your code, nor did you close the () when calling the function... try:

import sys
sys.exit()

I ran into this problem myself. I found that not specifying an input height, but using the font-height and padding combined, results in vertically aligned text.

For instance, lets say you want to have a 42px tall input box, with a font-size of 20px. You could simply find the difference between the input height and the font-size, divide it by two, and set your padding to that amount. In this case, you would have 22px total worth of padding, which is 11px on each side.

<input type="text" style="padding: 11px 0px 11px 0px; font-size: 20px;" />

That would give you a 42px tall input box with perfect vertical alignment.

Hope that helps.

This answer is for those with windows 8.1N! (and maybe all N versions)

The short answer is install Media Feature Pack for N and KN versions of Windows 8.1

Big thanks to Matej Drolc that had it solved in hit blog post here.

It depends on wether the locatoin is detected by different DNS resolution from different locations, or by IP address that you are browsing from.

If its by DNS, you could just modify your hosts file to point at the server used in europe. Get your friend to ping the address, to see if its different from the one yours resolves to.

To browse from a different IP address:

You can rent a VPS server. You can use putty / SSH to act as a proxy. I use this from time to time to brows from the US using a VPS server I rent in the US.

Having an account on a remote host may or may not be enough. Sadly, my dreamhost account, even though I have ssh access, does not allow proxying.

Just use substring: "apple".substring(3); will return le

To add to the other answers, Cygwin comes with the MinGW libraries and headers and you can compile without linking to the cygwin1.dll by using -mno-cygwin flag with gcc. I greatly prefer this to using plain MinGW and MSYS.

I will post the new "way" with androidx in a short answer (because in some case you does not need custom registry or contract). If you want more informations see : https://developer.android.com/training/basics/intents/result

Important : there is actually a bug with the backward compatibility of androidx so you have to add fragment_version in your gradle file. Otherwise you will get an exception "New result API error : Can only use lower 16 bits for requestCode".

dependencies {

    def activity_version = "1.2.0-beta01"
    // Java language implementation
    implementation "androidx.activity:activity:$activity_version"
    // Kotlin
    implementation "androidx.activity:activity-ktx:$activity_version"

    def fragment_version = "1.3.0-beta02"
    // Java language implementation
    implementation "androidx.fragment:fragment:$fragment_version"
    // Kotlin
    implementation "androidx.fragment:fragment-ktx:$fragment_version"
    // Testing Fragments in Isolation
    debugImplementation "androidx.fragment:fragment-testing:$fragment_version"
}

Now you just have to add this member variable of your activity. This use a predefined registry and generic contract.

public class MyActivity extends AppCompatActivity{

   ...

    /**
     * Activity callback API.
     */
    // https://developer.android.com/training/basics/intents/result
    private ActivityResultLauncher<Intent> mStartForResult = registerForActivityResult(new ActivityResultContracts.StartActivityForResult(),

            new ActivityResultCallback<ActivityResult>() {

                @Override
                public void onActivityResult(ActivityResult result) {
                    switch (result.getResultCode()) {
                        case Activity.RESULT_OK:
                            Intent intent = result.getData();
                            // Handle the Intent
                            Toast.makeText(MyActivity.this, "Activity returned ok", Toast.LENGTH_SHORT).show();
                            break;
                        case Activity.RESULT_CANCELED:
                            Toast.makeText(MyActivity.this, "Activity canceled", Toast.LENGTH_SHORT).show();
                            break;
                    }
                }
            });

Before new API you had :

btn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent = new Intent(MyActivity .this, EditActivity.class);
                startActivityForResult(intent, Constants.INTENT_EDIT_REQUEST_CODE);
            }
        });

You may notice that the request code is now generated (and holded) by the google framework. Your code become.

 btn.setOnClickListener(new View.OnClickListener() {
    
                @Override
                public void onClick(View v) {
                    Intent intent = new Intent(MyActivity .this, EditActivity.class);
                    mStartForResult.launch(intent);
                }
            });

Hope my answer will help some people !

There are lot of wonderful answers on this thread already. However I wanted to share my experience when I tried to solve "remove nth element from array" in ES5 context.

JavaScript arrays have different methods to add/remove elements from start or end. These are:

arr.push(ele) - To add element(s) at the end of the array 
arr.unshift(ele) - To add element(s) at the beginning of the array
arr.pop() - To remove last element from the array 
arr.shift() - To remove first element from the array 

Essentially none of the above methods can be used directly to remove nth element from the array.

A fact worth noting is that this is in contrast with java iterator's using which it is possible to remove nth element for a collection while iterating.

This basically leaves us with only one array method Array.splice to perform removal of nth element (there are other things you could do with these methods as well, but in the context of this question I am focusing on removal of elements):

Array.splice(index,1) - removes the element at the index 

Here is the code copied from original answer (with comments):

var arr = ["one", "two", "three", "four"];_x000D_
var i = arr.length; //initialize counter to array length _x000D_
_x000D_
while (i--) //decrement counter else it would run into IndexOutBounds exception_x000D_
{_x000D_
  if (arr[i] === "four" || arr[i] === "two") {_x000D_
    //splice modifies the original array_x000D_
    arr.splice(i, 1); //never runs into IndexOutBounds exception _x000D_
    console.log("Element removed. arr: ");_x000D_
_x000D_
  } else {_x000D_
    console.log("Element not removed. arr: ");_x000D_
  }_x000D_
  console.log(arr);_x000D_
}

Another noteworthy method is Array.slice. However the return type of this method is the removed elements. Also this doesn't modify original array. Modified code snippet as follows:

var arr = ["one", "two", "three", "four"];_x000D_
var i = arr.length; //initialize counter to array length _x000D_
_x000D_
while (i--) //decrement counter _x000D_
{_x000D_
  if (arr[i] === "four" || arr[i] === "two") {_x000D_
    console.log("Element removed. arr: ");_x000D_
    console.log(arr.slice(i, i + 1));_x000D_
    console.log("Original array: ");_x000D_
    console.log(arr);_x000D_
  }_x000D_
}

Having said that, we can still use Array.slice to remove nth element as shown below. However it is lot more code (hence inefficient)

var arr = ["one", "two", "three", "four"];_x000D_
var i = arr.length; //initialize counter to array length _x000D_
_x000D_
while (i--) //decrement counter _x000D_
{_x000D_
  if (arr[i] === "four" || arr[i] === "two") {_x000D_
    console.log("Array after removal of ith element: ");_x000D_
    arr = arr.slice(0, i).concat(arr.slice(i + 1));_x000D_
    console.log(arr);_x000D_
  }_x000D_
_x000D_
}

The Array.slice method is extremely important to achieve immutability in functional programming à la redux

If you want to do it this way then this is the syntax you're after;

IF EXISTS (SELECT * FROM tblGLUserAccess WHERE GLUserName ='xxxxxxxx') 
BEGIN
   SELECT 1 
END
ELSE
BEGIN
    SELECT 2
END

You don't strictly need the BEGIN..END statements but it's probably best to get into that habit from the beginning.

You can also generate source code from schema using jaxb2-maven-plugin plugin:

SELECT TOP 1 * FROM foo ORDER BY Dates DESC

Will return one result with the latest date.

SELECT * FROM foo WHERE foo.Dates = (SELECT MAX(Dates) FROM foo)

Will return all results that have the same maximum date, to the milissecond.

This is for SQL Server. I'll leave it up to you to use the DATEPART function if you want to use dates but not times.

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

The string that you pass to the constructor JSONObject has to be escaped with quote():

public static java.lang.String quote(java.lang.String string)

Your code would now be:

JSONObject jsonObj = new JSONObject.quote(jsonString.toString());
System.out.println(jsonString);
System.out.println("---------------------------");
System.out.println(jsonObj);

vim /etc/default/locale

add to it:

LC_ALL="en_US.UTF-8"

Sounds like you executed another statement in the same connection before traversing the result set from the first statement. If you're nesting the processing of two result sets from the same database, you're doing something wrong. The combination of those sets should be done on the database side.

@ComponentScan uses string array, like this:

@ComponentScan({"com.my.package.first","com.my.package.second"})

When you provide multiple package names in only one string, Spring interprets this as one package name, and thus can't find it.

Try setting position to absolute, ie.

#yourDiv{
    position: absolute;
    z-index: 10;
};

You can do:

def mul_table(n,i=1):
    print(n*i)
    if i !=10:
        mul_table(n,i+1)
mul_table(7)

angularBlogServices.factory('BlogPost', ['$resource',
    function($resource) {
        return $resource("./Post/:id", {}, {
            get:    {method: 'GET',    cache: true,  isArray: false},
            save:   {method: 'POST',   cache: false, isArray: false},
            update: {method: 'PUT',    cache: false, isArray: false},
            delete: {method: 'DELETE', cache: false, isArray: false}
        });
    }]);

set cache to be true.

In C, it is a common idiom to zero out the memory for a struct using memset:

struct x myStruct;
memset(&myStruct, 0, sizeof(myStruct));

Technically speaking, I don't believe that this is portable because it assumes that the NULL pointer on a machine is represented by the integer value 0, but it's used widely because on most machines this is the case.

If you move from C to C++, be careful not to use this technique on every object. C++ only makes this legal on objects with no member functions and no inheritance.

How about using fontawesome icon for Indian Rupee (INR).

Add font awesome CSS from CDN in the Head section of your HTML page:

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">

And then using the font like this:

<i class="fa fa-inr" aria-hidden="true"></i>

Just try installing through Anaconda prompt

new and delete are operators in c++; which can be overloaded too. malloc and free are function in c;

malloc returns null ptr when fails while new throws exception.

address returned by malloc need to by type casted again as it returns the (void*)malloc(size) New return the typed pointer.

For an alternative solution, check if you added your app to settings.gradle successfully

include ':app' 

Go to server explorer > Your Database > Right Click > properties > ConnectionString and copy the connection string and past the copied to connectiongstring code :)

select partition_name,column_name,high_value,partition_position
from ALL_TAB_PARTITIONS a , ALL_PART_KEY_COLUMNS b 
where table_name='YOUR_TABLE' and a.table_name = b.name;

This query lists the column name used as key and the allowed values. make sure, you insert the allowed values(high_value). Else, if default partition is defined, it would go there.

EDIT:

I presume, your TABLE DDL would be like this.

CREATE TABLE HE0_DT_INF_INTERFAZ_MES
  (
    COD_PAIS NUMBER,
    FEC_DATA NUMBER,
    INTERFAZ VARCHAR2(100)
  )
  partition BY RANGE(COD_PAIS, FEC_DATA)
  (
    PARTITION PDIA_98_20091023 VALUES LESS THAN (98,20091024)
  );

Which means I had created a partition with multiple columns which holds value less than the composite range (98,20091024);

That is first COD_PAIS <= 98 and Also FEC_DATA < 20091024

Combinations And Result:

98, 20091024     FAIL
98, 20091023     PASS
99, ********     FAIL
97, ********     PASS
 < 98, ********     PASS

So the below INSERT fails with ORA-14400; because (98,20091024) in INSERT is EQUAL to the one in DDL but NOT less than it.

SQL> INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
                                  VALUES(98, 20091024, 'CTA');  2
INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
            *
ERROR at line 1:
ORA-14400: inserted partition key does not map to any partition

But, we I attempt (97,20091024), it goes through

SQL> INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
  2                                    VALUES(97, 20091024, 'CTA');

1 row created.

See my comment. You need to include the full org.json library when running as android.jar only contains stubs to compile against.

In addition, you must remove the two instances of extra } in your JSON data following longitude.

   private final static String JSON_DATA =
     "{" 
   + "  \"geodata\": [" 
   + "    {" 
   + "      \"id\": \"1\"," 
   + "      \"name\": \"Julie Sherman\","                  
   + "      \"gender\" : \"female\"," 
   + "      \"latitude\" : \"37.33774833333334\"," 
   + "      \"longitude\" : \"-121.88670166666667\""
   + "    }," 
   + "    {" 
   + "      \"id\": \"2\"," 
   + "      \"name\": \"Johnny Depp\","          
   + "      \"gender\" : \"male\"," 
   + "      \"latitude\" : \"37.336453\"," 
   + "      \"longitude\" : \"-121.884985\""
   + "    }" 
   + "  ]" 
   + "}"; 

Apart from that, geodata is in fact not a JSONObject but a JSONArray.

Here is the fully working and tested corrected code:

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

public class ShowActivity {


  private final static String JSON_DATA =
     "{" 
   + "  \"geodata\": [" 
   + "    {" 
   + "      \"id\": \"1\"," 
   + "      \"name\": \"Julie Sherman\","                  
   + "      \"gender\" : \"female\"," 
   + "      \"latitude\" : \"37.33774833333334\"," 
   + "      \"longitude\" : \"-121.88670166666667\""
   + "    }," 
   + "    {" 
   + "      \"id\": \"2\"," 
   + "      \"name\": \"Johnny Depp\","          
   + "      \"gender\" : \"male\"," 
   + "      \"latitude\" : \"37.336453\"," 
   + "      \"longitude\" : \"-121.884985\""
   + "    }" 
   + "  ]" 
   + "}"; 

  public static void main(final String[] argv) throws JSONException {
    final JSONObject obj = new JSONObject(JSON_DATA);
    final JSONArray geodata = obj.getJSONArray("geodata");
    final int n = geodata.length();
    for (int i = 0; i < n; ++i) {
      final JSONObject person = geodata.getJSONObject(i);
      System.out.println(person.getInt("id"));
      System.out.println(person.getString("name"));
      System.out.println(person.getString("gender"));
      System.out.println(person.getDouble("latitude"));
      System.out.println(person.getDouble("longitude"));
    }
  }
}

Here's the output:

C:\dev\scrap>java -cp json.jar;. ShowActivity

After looking at my .gitmodules, it turned out I did have an uppercase letter where I should not have. So keep in mind, the .gitmodules directories are case sensitive

Private constructor and static methods on a class marked as final.

Use to_datetime, there is no need for a format string the parser is man/woman enough to handle it:

In [51]:
pd.to_datetime(df['I_DATE'])

Out[51]:
0   2012-03-28 14:15:00
1   2012-03-28 14:17:28
2   2012-03-28 14:50:50
Name: I_DATE, dtype: datetime64[ns]

To access the date/day/time component use the dt accessor:

In [54]:
df['I_DATE'].dt.date

Out[54]:
0    2012-03-28
1    2012-03-28
2    2012-03-28
dtype: object

In [56]:    
df['I_DATE'].dt.time

Out[56]:
0    14:15:00
1    14:17:28
2    14:50:50
dtype: object

You can use strings to filter as an example:

In [59]:
df = pd.DataFrame({'date':pd.date_range(start = dt.datetime(2015,1,1), end = dt.datetime.now())})
df[(df['date'] > '2015-02-04') & (df['date'] < '2015-02-10')]

Out[59]:
         date
35 2015-02-05
36 2015-02-06
37 2015-02-07
38 2015-02-08
39 2015-02-09

I was looking into this issue a bit for my own purposes; I had a slice of structs (including some pointers) and I wanted to make sure I got it right; ended up on this thread, and wanted to share my results.

To practice, I did a little go playground: https://play.golang.org/p/9i4gPx3lnY

which evals to this:

package main

import "fmt"

type Blah struct {
    babyKitten int
    kittenSays *string
}

func main() {
    meow := "meow"
    Blahs := []Blah{}
    fmt.Printf("Blahs: %v\n", Blahs)
    Blahs = append(Blahs, Blah{1, &meow})
    fmt.Printf("Blahs: %v\n", Blahs)
    Blahs = append(Blahs, Blah{2, &meow})
    fmt.Printf("Blahs: %v\n", Blahs)
    //fmt.Printf("kittenSays: %v\n", *Blahs[0].kittenSays)
    Blahs = nil
    meow2 := "nyan"
    fmt.Printf("Blahs: %v\n", Blahs)
    Blahs = append(Blahs, Blah{1, &meow2})
    fmt.Printf("Blahs: %v\n", Blahs)
    fmt.Printf("kittenSays: %v\n", *Blahs[0].kittenSays)
}

Running that code as-is will show the same memory address for both "meow" and "meow2" variables as being the same:

Blahs: []
Blahs: [{1 0x1030e0c0}]
Blahs: [{1 0x1030e0c0} {2 0x1030e0c0}]
Blahs: []
Blahs: [{1 0x1030e0f0}]
kittenSays: nyan

which I think confirms that the struct is garbage collected. Oddly enough, uncommenting the commented print line, will yield different memory addresses for the meows:

Blahs: []
Blahs: [{1 0x1030e0c0}]
Blahs: [{1 0x1030e0c0} {2 0x1030e0c0}]
kittenSays: meow
Blahs: []
Blahs: [{1 0x1030e0f8}]
kittenSays: nyan

I think this may be due to the print being deferred in some way (?), but interesting illustration of some memory mgmt behavior, and one more vote for:

[]MyStruct = nil

The best way, and it converts to a String as bonus ;)

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    try {
        //Dates to compare
        String CurrentDate=  "09/24/2015";
        String FinalDate=  "09/26/2015";

        Date date1;
        Date date2;

        SimpleDateFormat dates = new SimpleDateFormat("MM/dd/yyyy");

        //Setting dates
        date1 = dates.parse(CurrentDate);
        date2 = dates.parse(FinalDate);

        //Comparing dates
        long difference = Math.abs(date1.getTime() - date2.getTime());
        long differenceDates = difference / (24 * 60 * 60 * 1000);

        //Convert long to String
        String dayDifference = Long.toString(differenceDates);

        Log.e("HERE","HERE: " + dayDifference);
    }
    catch (Exception exception) {
        Log.e("DIDN'T WORK", "exception " + exception);
    }

group_concat() sounds like what you're looking for.

http://dev.mysql.com/doc/refman/5.0/en/group-by-functions.html#function_group-concat

since you're on mssql, i just googled "group_concat mssql" and found a bunch of hits to recreate group_concat functionality. here's one of the hits i found:

The .net framework overwrites 4.0 folder so run this command:

Register .net framework to IIS goto
Start -> run-> cmd -> run as administrator type:

cd C:\Windows\Microsoft.NET\Framework\v4.0.30319

Managed Code

Managed code is what Visual Basic .NET and C# compilers create. It runs on the CLR (Common Language Runtime), which, among other things, offers services like garbage collection, run-time type checking, and reference checking. So, think of it as, "My code is managed by the CLR."

Visual Basic and C# can only produce managed code, so, if you're writing an application in one of those languages you are writing an application managed by the CLR. If you are writing an application in Visual C++ .NET you can produce managed code if you like, but it's optional.

Unmanaged Code

Unmanaged code compiles straight to machine code. So, by that definition all code compiled by traditional C/C++ compilers is 'unmanaged code'. Also, since it compiles to machine code and not an intermediate language it is non-portable.

No free memory management or anything else the CLR provides.

Since you cannot create unmanaged code with Visual Basic or C#, in Visual Studio all unmanaged code is written in C/C++.

Mixing the two

Since Visual C++ can be compiled to either managed or unmanaged code it is possible to mix the two in the same application. This blurs the line between the two and complicates the definition, but it's worth mentioning just so you know that you can still have memory leaks if, for example, you're using a third party library with some badly written unmanaged code.

Here's an example I found by googling:

#using <mscorlib.dll>
using namespace System;

#include "stdio.h"

void ManagedFunction()
{
    printf("Hello, I'm managed in this section\n");
}

#pragma unmanaged
UnmanagedFunction()
{
    printf("Hello, I am unmanaged through the wonder of IJW!\n");
    ManagedFunction();
}

#pragma managed
int main()
{
    UnmanagedFunction();
    return 0;
}

Some simple ideas to get you going:

In PHP you can do it like this:

if (!array_key_exists(explode('=', explode('&', $_GET))) {
  /* add the view-all bit here */
}

In javascript:

if(!location.search.match(/view\-all=/)) {
  location.href = location.href + '&view-all=Yes';
}

You can check scrollHeight and clientHeight with scrollTop to scroll to bottom of div like code below.

$('#div').scroll(function (event) {_x000D_
  if ((parseInt($('#div')[0].scrollHeight) - parseInt(this.clientHeight)) == parseInt($('#div').scrollTop())) _x000D_
  {_x000D_
    console.log("this is scroll bottom of div");_x000D_
  }_x000D_
  _x000D_
});

In addition to @csgillespie's answer, segments is also vectorised to help with this sort of thing:

plot (x, y, ylim=c(0,6))
segments(x,y-sd,x,y+sd)
epsilon <- 0.02
segments(x-epsilon,y-sd,x+epsilon,y-sd)
segments(x-epsilon,y+sd,x+epsilon,y+sd)

You can also write this:

SqlCommand cmd=new SqlCommand ("insert into time(project,iteration) values (@project, @iteration)", conn);
cmd.Parameters.AddWithValue("@project",name1.SelectedValue);
cmd.Parameters.AddWithValue("@iteration",iteration.SelectedValue);

These guys seem to have a solution for this, but I haven't tried yet. They also have a demo version of the converter.

if "allow zero datetime=true" is not working then use the following sollutions:-

Add this to your connection string: "allow zero datetime=no" - that made the type cast work perfectly.

This works well for coping entire records.

UPDATE your_table
SET new_field = sourse_field

You can also add android:noHistory="true" to your Activity tag in AndroidManifest.xml.

<activity
            ...
            android:noHistory="true">
</activity>

Syntax is Shown below:

"your condition"? "step if true":"step if condition fails"

Actually I am preferring to use NEW_BROKER ,it is working fine on all cases:

ALTER DATABASE [dbname] SET NEW_BROKER WITH ROLLBACK IMMEDIATE;

The recommended way (as noted in codex):

$wpdb->insert( $table_name, array('column_name_1'=>'hello', 'other'=> 123), array( '%s', '%d' ) );

So, you'd better to sanitize values - ALWAYS CONSIDER THE SECURITY.

If you want to get this out of your table using SQL, take a look at the following functions that will help you: SUBSTRING and CHARINDEX. You can use those to trim your entries.

A possible query will look like this (where col is the name of the column that contains your image directories:

SELECT SUBSTRING(col, LEN(SUBSTRING(col, 0, LEN(col) - CHARINDEX ('/', col))) + 1, 
    LEN(col) - LEN(SUBSTRING(col, 0, LEN(col) - CHARINDEX ('/', col))) - LEN(SUBSTRING(
    col, CHARINDEX ('.', col), LEN(col))));

Bit of an ugly beast. It also depends on the standard format of 'dir/name.ext'.

Edit:
This one (inspired by praveen) is more generic and deals with extensions of different length:

SELECT SUBSTRING(col, LEN(LEFT(col, CHARINDEX ('/', col))) + 1, LEN(col) - LEN(LEFT(col, 
    CHARINDEX ('/', col))) - LEN(RIGHT(col, LEN(col) - CHARINDEX ('.', col))) - 1);

All of the above answers were perfectly clear and complete, but just for the record I'd like to confirm that the meaning of * and ** in python has absolutely no similarity with the meaning of similar-looking operators in C.

They are called the argument-unpacking and keyword-argument-unpacking operators.

Do you mean append?

>>> x = [1,2,3]
>>> y = [4,5,6]
>>> x.append(y)
>>> x
[1, 2, 3, [4, 5, 6]]

Or merge?

>>> x = [1,2,3]
>>> y = [4,5,6]
>>> x + y
[1, 2, 3, 4, 5, 6]
>>> x.extend(y)
>>> x
[1, 2, 3, 4, 5, 6] 

This worked for me with Nginx, Node server and Angular 4

Edit your nginx web server config file as:

server {
listen 80;
server_name 52.xx.xxx.xx;

location / {
    proxy_set_header   X-Forwarded-For $remote_addr;
    proxy_set_header   Host $http_host;
    proxy_pass         "http://127.0.0.1:4200";
    proxy_http_version 1.1;
    proxy_set_header   Upgrade $http_upgrade;
    proxy_set_header   Connection "upgrade";
}

Here this works smoothly:

#myOwnTable td { padding: 6px 0 6px 0;}

I suppose you could work out a more finely-grained layout by specifying which td if need be.

If you want to lock the main view of your app to portrait, but want to open popup views in landscape, and you are using tabBarController as rootViewController as I am, you can use this code on your AppDelegate.

AppDelegate.h

@interface AppDelegate : UIResponder <UIApplicationDelegate, UITabBarControllerDelegate>

@property (strong, nonatomic) UIWindow *window;
@property (strong, nonatomic) UITabBarController *tabBarController;

@end

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    // Create a tab bar and set it as root view for the application
    self.tabBarController = [[UITabBarController alloc] init];
    self.tabBarController.delegate = self;
    self.window.rootViewController = self.tabBarController;

    ...
}

- (NSUInteger)tabBarControllerSupportedInterfaceOrientations:(UITabBarController *)tabBarController
{
    return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)tabBarControllerPreferredInterfaceOrientationForPresentation:(UITabBarController *)tabBarController
{
    return UIInterfaceOrientationPortrait;
}

It works very well.

In your viewController you want to be presented in landscape, you simply use the following:

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscape;
}

- (BOOL)shouldAutorotate {
    return YES;
}

I've seen people mention a rename command, but it is not routinely available on Unix systems (as opposed to Linux systems, say, or Cygwin - on both of which, rename is an executable rather than a script). That version of rename has a fairly limited functionality:

rename from to file ...

It replaces the from part of the file names with the to, and the example given in the man page is:

rename foo foo0 foo? foo??

This renames foo1 to foo01, and foo10 to foo010, etc.

I use a Perl script called rename, which I originally dug out from the first edition Camel book, circa 1992, and then extended, to rename files.

#!/bin/perl -w
#
# @(#)$Id: rename.pl,v 1.7 2008/02/16 07:53:08 jleffler Exp $
#
# Rename files using a Perl substitute or transliterate command

use strict;
use Getopt::Std;

my(%opts);
my($usage) = "Usage: $0 [-fnxV] perlexpr [filenames]\n";
my($force) = 0;
my($noexc) = 0;
my($trace) = 0;

die $usage unless getopts('fnxV', \%opts);

if ($opts{V})
{
    printf "%s\n", q'RENAME Version $Revision: 1.7 $ ($Date: 2008/02/16 07:53:08 $)';
    exit 0;
}
$force = 1 if ($opts{f});
$noexc = 1 if ($opts{n});
$trace = 1 if ($opts{x});

my($op) = shift;
die $usage unless defined $op;

if (!@ARGV) {
    @ARGV = <STDIN>;
    chop(@ARGV);
}

for (@ARGV)
{
    if (-e $_ || -l $_)
    {
        my($was) = $_;
        eval $op;
        die $@ if $@;
        next if ($was eq $_);
        if ($force == 0 && -f $_)
        {
            print STDERR "rename failed: $was - $_ exists\n";
        }
        else
        {
            print "+ $was --> $_\n" if $trace;
            print STDERR "rename failed: $was - $!\n"
                unless ($noexc || rename($was, $_));
        }
    }
    else
    {
        print STDERR "$_ - $!\n";
    }
}

This allows you to write any Perl substitute or transliterate command to map file names. In the specific example requested, you'd use:

rename 's/^/new./' original.filename

your panel class don't have a constructor that accepts a string

try change

RLS_strid_panel p = new RLS_strid_panel(namn1);

to

RLS_strid_panel p = new RLS_strid_panel();
p.setName1(name1);

Please check out my component that will help you to allow only a particular data type. Currently supporting integer, decimal, string and time(HH:MM).

• string - String is allowed with optional max length
• integer - Integer only allowed with optional max value
• decimal - Decimal only allowed with optional decimal points and max value (by default 2 decimal points)
• time - 24 hr Time format(HH:MM) only allowed

Hope that helps.

I think that is controlled by the expose_php setting in PHP.ini:

expose_php = off

Decides whether PHP may expose the fact that it is installed on the server (e.g. by adding its signature to the Web server header). It is no security threat in any way, but it makes it possible to determine whether you use PHP on your server or not.

There is no direct security risk, but as David C notes, exposing an outdated (and possibly vulnerable) version of PHP may be an invitation for people to try and attack it.

If you don't need the leading and trailing spaces :

In case of Windows(in my case XP):-

1. Check the directory where tomcat is installed.
2. Open the directory called \conf in it.
3. Then search file server.xml
4. Open that file and check what is the connector port for HTTP,whre you will found something like 8009,8080 etc.
5. Suppose it found 8009,use that port as "/localhost:8009/" in your web-browser with HTTP protocol. Hope this will work !

Try the following

Dictionary<int, DateTime> existingItems = 
    (from ObjType ot in TableObj).ToDictionary(x => x.Key);

Or the fully fledged type inferenced version

var existingItems = TableObj.ToDictionary(x => x.Key);

You can convert .jar file to .exe on these ways:

_{(source: viralpatel.net)}

1- JSmooth .exe wrapper:
JSmooth is a Java Executable Wrapper. It creates native Windows launchers (standard .exe) for your java applications. It makes java deployment much smoother and user-friendly, as it is able to find any installed Java VM by itself. When no VM is available, the wrapper can automatically download and install a suitable JVM, or simply display a message or redirect the user to a web site.

JSmooth provides a variety of wrappers for your java application, each of them having their own behaviour: Choose your flavour!

Download: http://jsmooth.sourceforge.net/

2- JarToExe 1.8
Jar2Exe is a tool to convert jar files into exe files. Following are the main features as describe in their website:

• Can generate “Console”, “Windows GUI”, “Windows Service” three types of exe files.
• Generated exe files can add program icons and version information.
• Generated exe files can encrypt and protect java programs, no temporary files will be generated when program runs.
• Generated exe files provide system tray icon support.
• Generated exe files provide record system event log support.
• Generated windows service exe files are able to install/uninstall itself, and support service pause/continue.
• New release of x64 version, can create 64 bits executives. (May 18, 2008)
• Both wizard mode and command line mode supported. (May 18, 2008)

Download: http://www.brothersoft.com/jartoexe-75019.html

3- Executor
Package your Java application as a jar, and Executor will turn the jar into a Windows exe file, indistinguishable from a native application. Simply double-clicking the exe file will invoke the Java Runtime Environment and launch your application.

Download: http://mpowers.net/executor/

EDIT: The above link is broken, but here is the page (with working download) from the Internet Archive. http://web.archive.org/web/20090316092154/http://mpowers.net/executor/

4- Advanced Installer
Advanced Installer lets you create Windows MSI installs in minutes. This also has Windows Vista support and also helps to create MSI packages in other languages.
Download: http://www.advancedinstaller.com/ Let me know other tools that you have used to convert JAR to EXE.

The earlier version of the accepted answer (md5(uniqid(mt_rand(), true))) is insecure and only offers about 2^60 possible outputs -- well within the range of a brute force search in about a week's time for a low-budget attacker:

• mt_rand() is predictable (and only adds up to 31 bits of entropy)
• uniqid() only adds up to 29 bits of entropy
• md5() doesn't add entropy, it just mixes it deterministically

Since a 56-bit DES key can be brute-forced in about 24 hours, and an average case would have about 59 bits of entropy, we can calculate 2^59 / 2^56 = about 8 days. Depending on how this token verification is implemented, it might be possible to practically leak timing information and infer the first N bytes of a valid reset token.

Since the question is about "best practices" and opens with...

I want to generate identifier for forgot password

...we can infer that this token has implicit security requirements. And when you add security requirements to a random number generator, the best practice is to always use a cryptographically secure pseudorandom number generator (abbreviated CSPRNG).

Using a CSPRNG

In PHP 7, you can use bin2hex(random_bytes($n)) (where $n is an integer larger than 15).

In PHP 5, you can use random_compat to expose the same API.

Alternatively, bin2hex(mcrypt_create_iv($n, MCRYPT_DEV_URANDOM)) if you have ext/mcrypt installed. Another good one-liner is bin2hex(openssl_random_pseudo_bytes($n)).

Separating the Lookup from the Validator

Pulling from my previous work on secure "remember me" cookies in PHP, the only effective way to mitigate the aforementioned timing leak (typically introduced by the database query) is to separate the lookup from the validation.

If your table looks like this (MySQL)...

CREATE TABLE account_recovery (
    id INTEGER(11) UNSIGNED NOT NULL AUTO_INCREMENT 
    userid INTEGER(11) UNSIGNED NOT NULL,
    token CHAR(64),
    expires DATETIME,
    PRIMARY KEY(id)
);

... you need to add one more column, selector, like so:

CREATE TABLE account_recovery (
    id INTEGER(11) UNSIGNED NOT NULL AUTO_INCREMENT 
    userid INTEGER(11) UNSIGNED NOT NULL,
    selector CHAR(16),
    token CHAR(64),
    expires DATETIME,
    PRIMARY KEY(id),
    KEY(selector)
);

Use a CSPRNG When a password reset token is issued, send both values to the user, store the selector and a SHA-256 hash of the random token in the database. Use the selector to grab the hash and User ID, calculate the SHA-256 hash of the token the user provides with the one stored in the database using hash_equals().

Example Code

Generating a reset token in PHP 7 (or 5.6 with random_compat) with PDO:

$selector = bin2hex(random_bytes(8));
$token = random_bytes(32);

$urlToEmail = 'http://example.com/reset.php?'.http_build_query([
    'selector' => $selector,
    'validator' => bin2hex($token)
]);

$expires = new DateTime('NOW');
$expires->add(new DateInterval('PT01H')); // 1 hour

$stmt = $pdo->prepare("INSERT INTO account_recovery (userid, selector, token, expires) VALUES (:userid, :selector, :token, :expires);");
$stmt->execute([
    'userid' => $userId, // define this elsewhere!
    'selector' => $selector,
    'token' => hash('sha256', $token),
    'expires' => $expires->format('Y-m-d\TH:i:s')
]);

Verifying the user-provided reset token:

$stmt = $pdo->prepare("SELECT * FROM account_recovery WHERE selector = ? AND expires >= NOW()");
$stmt->execute([$selector]);
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
if (!empty($results)) {
    $calc = hash('sha256', hex2bin($validator));
    if (hash_equals($calc, $results[0]['token'])) {
        // The reset token is valid. Authenticate the user.
    }
    // Remove the token from the DB regardless of success or failure.
}

These code snippets are not complete solutions (I eschewed the input validation and framework integrations), but they should serve as an example of what to do.

Let me make a recap.

When you build a view containing object of different owners, those other owners have to grant "with grant option" to the owner of the view. So, the view owner can grant to other users or schemas....

Example: User_a is the owner of a table called mine_a User_b is the owner of a table called yours_b

Let's say user_b wants to create a view with a join of mine_a and yours_b

For the view to work fine, user_a has to give "grant select on mine_a to user_b with grant option"

Then user_b can grant select on that view to everybody.

It is standard matplotlib.pyplot:

...
import matplotlib.pyplot as plt
plt.ylim(10, 40)

Or simpler, as mwaskom comments below:

ax.set(ylim=(10, 40))

You can't use IF like that. You can do what you want with AND and OR:

SELECT t.first_name,
       t.last_name,
       t.employid,
       t.status
  FROM employeetable t
 WHERE ((status_flag = STATUS_ACTIVE   AND t.status = 'A')
     OR (status_flag = STATUS_INACTIVE AND t.status = 'T')
     OR (source_flag = SOURCE_FUNCTION AND t.business_unit = 'production')
     OR (source_flag = SOURCE_USER     AND t.business_unit = 'users'))
   AND t.first_name LIKE firstname
   AND t.last_name  LIKE lastname
   AND t.employid   LIKE employeeid;

I had similar requirement of running a LAMP stack, Mongo DB and my own services

Docker is OS based virtualisation, which is why it isolates its container around a running process, hence it requires least one process running in FOREGROUND.

So you provide your own startup script as the entry point, thus your startup script becomes an extended Docker image script, in which you can stack any number of the services as far as AT LEAST ONE FOREGROUND SERVICE IS STARTED, WHICH TOO TOWARDS THE END

So my Docker image file has two line below in the very end:

COPY myStartupScript.sh /usr/local/myscripts/myStartupScript.sh
CMD ["/bin/bash", "/usr/local/myscripts/myStartupScript.sh"]

In my script I run all MySQL, MongoDB, Tomcat etc. In the end I run my Apache as a foreground thread.

source /etc/apache2/envvars
/usr/sbin/apache2 -DFOREGROUND

This enables me to start all my services and keep the container alive with the last service started being in the foreground

Hope it helps

UPDATE: Since I last answered this question, new things have come up like Docker compose, which can help you run each service on its own container, yet bind all of them together as dependencies among those services, try knowing more about docker-compose and use it, it is more elegant way unless your need does not match with it.

Interestingly none of the answers mentioned that And and Or in VB.NET are bit operators whereas OrElse and AndAlso are strictly Boolean operators.

Dim a = 3 OR 5 ' Will set a to the value 7, 011 or 101 = 111
Dim a = 3 And 5 ' Will set a to the value 1, 011 and 101 = 001
Dim b = 3 OrElse 5 ' Will set b to the value true and not evaluate the 5
Dim b = 3 AndAlso 5 ' Will set b to the value true after evaluating the 5
Dim c = 0 AndAlso 5 ' Will set c to the value false and not evaluate the 5

Note: a non zero integer is considered true; Dim e = not 0 will set e to -1 demonstrating Not is also a bit operator.

|| and && (the C# versions of OrElse and AndAlso) return the last evaluated expression which would be 3 and 5 respectively. This lets you use the idiom v || 5 in C# to give 5 as the value of the expression when v is null or (0 and an integer) and the value of v otherwise. The difference in semantics can catch a C# programmer dabbling in VB.NET off guard as this "default value idiom" doesn't work in VB.NET.

So, to answer the question: Use Or and And for bit operations (integer or Boolean). Use OrElse and AndAlso to "short circuit" an operation to save time, or test the validity of an evaluation prior to evaluating it. If valid(evaluation) andalso evaluation then or if not (unsafe(evaluation) orelse (not evaluation)) then

Bonus: What is the value of the following?

Dim e = Not 0 And 3

Agreed that you've to get authenticated to admin db and needs at least a role with correct privileges which would avoid 'local host exception' from DB(this is for mongoDB's hosted on-premises), though you've everything in place & still getting not authorized exceptions on almost every command, while accessing mongoDB which got created using Mongo Atlas, then here is the place where you might know the reason, why :

} else {

If you look this file Namespace is not the first statement.

<?php
class BulletProofException extends Exception{}

namespace BulletProof;

You can try to move the namespace over the class definition.

Two steps. First, extend Activity class

class Example extends Activity

Second: Use this code

 DisplayMetrics displayMetrics = new DisplayMetrics();
 WindowManager windowmanager = (WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE);
 windowmanager.getDefaultDisplay().getMetrics(displayMetrics);
 int deviceWidth = displayMetrics.widthPixels;
 int deviceHeight = displayMetrics.heightPixels;

libeay32.dll and ssleay32.dll have to be path-accessible for php_curl.dll loading to succeed.

But copying them into Apache's ServerRoot, Apache's \bin\, Window's \System32\, or even worse into the Windows main directory is a bad hack and may not even work with newer PHP versions.

The right way to do it is to add the PHP path to the Windows Path variable.

1. In Control Panel -> System click on Advanced System Settings or press WIN+R and type SystemPropertiesAdvanced
2. Click the button Environment Variables.
3. Under System Variables you will find the Path variable. Edit it and prepend C:\PHP; to it - or whatever the path to your PHP folder is.
   (Hint: If your PHP folder contains spaces like C:\Program Files\PHP you may need to use the short filename form here, i.e. C:\Progra~1\PHP.)
4. Then fully stop Apache and start it again (a simple restart might not be enough).

Update 2017-05:
I changed the instructions above to prepend the Path variable with the PHP path instead of appending to it. This makes sure that the DLLs in the PHP path are used and not any other (outdated) versions in other paths of the system.

Update 2018-04:
If you have already chosen the wrong way and copied any of the PHP DLLs to Apache or Windows paths, then I strongly recommend that you remove them again! If you don't, you might get into trouble when you later try to update PHP. If a new PHP version brings new versions of these DLLs, but your old DLLs still linger around in system or webserver paths, these old DLLs might be found first. This will most certainly prevent the PHP interpreter from starting. Such errors can be very hard to understand and resolve. So better clean up now and remove any of the mentioned DLLs from Windows and Apache paths, if you copied them there.
(Thanks to @EdmundTam and @WasimA. for pointing out this problem in the comments!)

Update 2019-10:
Tip: To find all copies of these DLLs and check whether you might have placed them in the wrong folders, you can use the following commands in a Windows Command Prompt window:

dir c:\libeay32.dll /s
dir c:\ssleay32.dll /s

Be warned that these commands may take some time to complete as they search through the entire directory structure of your system drive C:.

Update 2020-08:
If your PHP folder contains spaces (i.e. C:\Program Files\PHP) you may need to use the short filename form in the Path variable at step 3 (i.e. C:\Progra~1\PHP). Thanks to @onee for this tip!

in java you can inherit from one (abstract) class to "provide" functionality and you can implement many interfaces to "ensure" functionality

I did some modification to the SMNALLY's code so it can run in Python 3.5.2. This is my result:

#Import the following library to make use of the DispatchEx to run the macro
import win32com.client as wincl

def runMacro():

    if os.path.exists("C:\\Users\\Dev\\Desktop\\Development\\completed_apps\\My_Macr_Generates_Data.xlsm"):

    # DispatchEx is required in the newest versions of Python.
    excel_macro = wincl.DispatchEx("Excel.application")
    excel_path = os.path.expanduser("C:\\Users\\Dev\\Desktop\\Development\\completed_apps\\My_Macr_Generates_Data.xlsm")
    workbook = excel_macro.Workbooks.Open(Filename = excel_path, ReadOnly =1)
    excel_macro.Application.Run\
        ("ThisWorkbook.Template2G")
    #Save the results in case you have generated data
    workbook.Save()
    excel_macro.Application.Quit()  
    del excel_macro

import time
import datetime

# use mktime to step by one day
# end - the last day, numdays - count of days to step back
def gen_dates_list(end, numdays):
  start = end - datetime.timedelta(days=numdays+1)
  end   = int(time.mktime(end.timetuple()))
  start = int(time.mktime(start.timetuple()))
  # 86400 s = 1 day
  return xrange(start, end, 86400)

# if you need reverse the list of dates
for dt in reversed(gen_dates_list(datetime.datetime.today(), 100)):
    print datetime.datetime.fromtimestamp(dt).date()

Even though, I have been using 400 to represent logical errors also, I have to say that returning 400 is wrong in this case because of the way the spec reads. Here is why i think so, the logical error could be that a relationship with another entity was failing or not satisfied and making changes to the other entity could cause the same exact to pass later. Like trying to (completely hypothetical) add an employee as a member of a department when that employee does not exist (logical error). Adding employee as member request could fail because employee does not exist. But the same exact request could pass after the employee has been added to the system.

Just my 2 cents ... We need lawyers & judges to interpret the language in the RFC these days :)

Thank You, Vish

First we need to find a Button:

Button mButton = (Button) findViewById(R.id.my_button);

After that, you must implement View.OnClickListener and there you should find the TextView and execute the method setText:

mButton.setOnClickListener(new View.OnClickListener {
    public void onClick(View v) {
        final TextView mTextView = (TextView) findViewById(R.id.my_text_view);
        mTextView.setText("Some Text");
    }
});

@ChrisPratt's answer about the use of Display Template is wrong. The correct code to make it work is:

@model DateTime?

@if (Model.HasValue)
{
    @Convert.ToDateTime(Model).ToString("MM/dd/yyyy")
}

That's because .ToString() for Nullable<DateTime> doesn't accept Format parameter.

There is GitHub Enterprise to satisfy your needs. And there is an open source "clone" of Github Enterprise.

PS: Now Github provides unlimited private repositories, bitbucket does the same. you can give a try to both. There are several other solutions as well.

Let me fix your code

inventory=["sword", "potion", "armour", "bow"]
print(inventory)
print("\ncommands: use (remove) and pickup (add)")
selection=input("choose a command [use/pickup]")

if selection == "use":
    print(inventory)
    inventory.remove(input("What do you want to use? "))
    print(inventory)
elif selection == "pickup":
    print(inventory)
    add=input("What do you want to pickup? ")
    newinv=inventory+[str(add)] #use '[str(add)]' or list(str(add))
    print(newinv)

The error is you are adding string and list, you should use list or [] to make the string become list type

How to avoid copy-paste?

Let's face it: this one appears a lot when recording macros:

Range("X1").Select
Selection.Copy
Range("Y9).Select
Selection.Paste

While the only thing the person wants is:

Range("Y9").Value = Range("X1").Value

Therefore, instead of using copy-paste in VBA macros, I'd advise the following simple approach:

Destination_Range.Value = Source_Range.Value

HAVING specifies a search condition for a group or an aggregate function used in SELECT statement.

Source

It happens because your maven plugin try to connect to an HTTPS remote repository (https://repo.maven.apache.org/maven2) or (https://repo1.maven.apache.org).

Some time ago, you could to change these URL's to use HTTP instead use HTTPS, but since January 15th 2020, these URL's doesn't work any more, only the HTTPS URL's.

As an easy way to fix this problem, you can use the insecure Maven URL in the settings.xml file. So, you need to change ALL of yours references above mencioned to: http://insecure.repo1.maven.org/maven2/

TIP: Your JAVA_HOME variable always needs to point to your JDK path, not to your JRE path, for example: "C:\Program Files\Java\jdk1.7.0_80".

I accidentally created a migration with a bad name (command: php artisan migrate:make). I did not run (php artisan migrate) the migration, so I decided to remove it. My steps:

1. Manually delete the migration file under app/database/migrations/my_migration_file_name.php
2. Reset the composer autoload files: composer dump-autoload
3. Relax

If you did run the migration (php artisan migrate), you may do this:

a) Run migrate:rollback - it is the right way to undo the last migration (Thnx @Jakobud)

b) If migrate:rollback does not work, do it manually (I remember bugs with migrate:rollback in previous versions):

1. Manually delete the migration file under app/database/migrations/my_migration_file_name.php
2. Reset the composer autoload files: composer dump-autoload
3. Modify your database: Remove the last entry from the migrations table

Best way i learnt is using express with html files as express gives lots of advantage. Also you can extend it to a Heroku platform if you want..Just saying :)

var express = require("express");
var app     = express();
var path    = require("path");


app.get('/',function(req,res){
  res.sendFile(path.join(__dirname+'/index.html'));
});

app.listen(3000);



console.log("Running at Port 3000");

Clean and best..!!!

Single Threaded Event Loop Model Processing Steps:

• Clients Send request to Web Server.

• Node JS Web Server internally maintains a Limited Thread pool to provide services to the Client Requests.

• Node JS Web Server receives those requests and places them into a Queue. It is known as “Event Queue”.

• Node JS Web Server internally has a Component, known as “Event Loop”. Why it got this name is that it uses indefinite loop to receive requests and process them.

• Event Loop uses Single Thread only. It is main heart of Node JS Platform Processing Model.

• Event Loop checks any Client Request is placed in Event Queue. If not then wait for incoming requests for indefinitely.

• If yes, then pick up one Client Request from Event Queue

  1. Starts process that Client Request
  2. If that Client Request Does Not requires any Blocking IO Operations, then process everything, prepare response and send it back to client.
  3. If that Client Request requires some Blocking IO Operations like interacting with Database, File System, External Services then it will follow different approach
• Checks Threads availability from Internal Thread Pool
• Picks up one Thread and assign this Client Request to that thread.

• That Thread is responsible for taking that request, process it, perform Blocking IO operations, prepare response and send it back to the Event Loop

You have to grant the Superuser right to the shell app (com.anroid.shell). In my case, I use Magisk to root my phone Nexsus 6P (Oreo 8.1). So I can grant Superuser right in the Magisk Manager app, whih is in the left upper option menu.

Go ahead and use Lombok, you can if necessary "delombok" your code afterwards http://projectlombok.org/features/delombok.html

As others have pointed out, the cd command needs to start with a percentage sign:

%cd SwitchFrequencyAnalysis

Difference between % and !

Google Colab seems to inherit these syntaxes from Jupyter (which inherits them from IPython). Jake VanderPlas explains this IPython behaviour here. You can see the excerpt below.

If you play with IPython's shell commands for a while, you might notice that you cannot use !cd to navigate the filesystem:

In [11]: !pwd 
/home/jake/projects/myproject

In [12]: !cd ..

In [13]: !pwd 
/home/jake/projects/myproject 

The reason is that shell commands in the notebook are executed in a temporary subshell. If you'd like to change the working directory in a more enduring way, you can use the %cd magic command:

In [14]: %cd ..
/home/jake/projects

Another way to look at this: you need % because changing directory is relevant to the environment of the current notebook but not to the entire server runtime.

In general, use ! if the command is one that's okay to run in a separate shell. Use % if the command needs to be run on the specific notebook.

I want to change the width and height of a div. data attributes did not change it. Instead I use:

var size = $("#theme_photo_size").val().split("x");
$("#imageupload_img").width(size[0]);
$("#imageupload_img").attr("data-width", size[0]);
$("#imageupload_img").height(size[1]);
$("#imageupload_img").attr("data-height", size[1]);

be careful:

$("#imageupload_img").data("height", size[1]); //did not work

did not set it

$("#imageupload_img").attr("data-height", size[1]); // yes it worked!

this has set it.

Along the lines of erik's response, you should also be able to calculate the ROC directly by comparing all possible pairs of values from pos.scores and neg.scores:

score.pairs <- merge(pos.scores, neg.scores)
names(score.pairs) <- c("pos.score", "neg.score")
sum(score.pairs$pos.score > score.pairs$neg.score) / nrow(score.pairs)

Certainly less efficient than the sample approach or the pROC::auc, but more stable than the former and requiring less installation than the latter.

Related: when I tried this it gave similar results to pROC's value, but not exactly the same (off by 0.02 or so); the result was closer to the sample approach with very high N. If anyone has ideas why that might be I'd be interested.

You can use this method to pick image from gallery. Only images will be displayed.

public void pickImage() {
    Intent intent = new Intent(Intent.ACTION_PICK,
            MediaStore.Images.Media.INTERNAL_CONTENT_URI);
    intent.setType("image/*");
    intent.putExtra("crop", "true");
    intent.putExtra("scale", true);
    intent.putExtra("outputX", 256);
    intent.putExtra("outputY", 256);
    intent.putExtra("aspectX", 1);
    intent.putExtra("aspectY", 1);
    intent.putExtra("return-data", true);
    startActivityForResult(intent, 1);
}

and override onActivityResult as

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode != RESULT_OK) {
            return;
        }
        if (requestCode == 1) {
            final Bundle extras = data.getExtras();
            if (extras != null) {
                //Get image
                Bitmap newProfilePic = extras.getParcelable("data");
            }
        }
    }

Owl Carousel version matters a lot, as of now (2nd Aug 2020) the version is 2.3.4 and the right options for autoplay are:

$(".owl-carousel").owlCarousel({
    autoplay : true,
    autoplayTimeout: 3000,//Autoplay interval timeout.
    loop:true,//Infinity loop. Duplicate last and first items to get loop illusion.
    items:1 //The number of items you want to see on the screen.
});

I also vote for GemBox.Spreadsheet.

Very fast and easy to use, with tons of examples on their site.

Took my reporting tasks on a whole new level of execution speed.

For myself, I would assume unsigned int is platform specific. Integer could be 8 bits, 16 bits, 32 bits or even 64 bits.

DWORD in the other hand, specifies its own size, which is Double Word. Word are 16 bits so DWORD will be known as 32 bit across all platform

An old tip...

var daddy = window.self;
daddy.opener = window.self;
daddy.close();

After a lot of fiddling, got it working (only tested in Webkit) using:

font-family: "HelveticaNeue-CondensedBold";

font-stretch was dropped between CSS2 and 2.1, though is back in CSS3, but is only supported in IE9 (never thought I'd be able to say that about any CSS prop!)

This works because I'm using the postscript name (find the font in Font Book, hit cmd+I), which is non-standard behaviour. It's probably worth using:

font-family: "HelveticaNeue-CondensedBold", "Helvetica Neue";

As a fallback, else other browsers might default to serif if they can't work it out.

Snuffin solution seems quite slow to execute when you've got plenty of rows and Mark Byers/Rick James and Bluefeet solutions doesn't work on my environnement (MySQL 5.6) because order by is applied after execution of select, so here is a variant of Marc Byers/Rick James solutions to fix this issue (with an extra imbricated select):

select person, groupname, age
from
(
    select person, groupname, age,
    (@rn:=if(@prev = groupname, @rn +1, 1)) as rownumb,
    @prev:= groupname 
    from 
    (
        select person, groupname, age
        from persons 
        order by groupname ,  age desc, person
    )   as sortedlist
    JOIN (select @prev:=NULL, @rn :=0) as vars
) as groupedlist 
where rownumb<=2
order by groupname ,  age desc, person;

I tried similar query on a table having 5 millions rows and it returns result in less than 3 seconds

There's one reason to use an out param which has not already been mentioned: the calling method is obliged to receive it. If your method produces a value which the caller should not discard, making it an out forces the caller to specifically accept it:

 Method1();  // Return values can be discard quite easily, even accidentally

 int  resultCode;
 Method2(out resultCode);  // Out params are a little harder to ignore

Of course the caller can still ignore the value in an out param, but you've called their attention to it.

This is a rare need; more often, you should use an exception for a genuine problem or return an object with state information for an "FYI", but there could be circumstances where this is important.

Like the others said:

inputString.split('\n')  # --> ['Line 1', 'Line 2', 'Line 3']

This is identical to the above, but the string module's functions are deprecated and should be avoided:

import string
string.split(inputString, '\n')  # --> ['Line 1', 'Line 2', 'Line 3']

Alternatively, if you want each line to include the break sequence (CR,LF,CRLF), use the splitlines method with a True argument:

inputString.splitlines(True)  # --> ['Line 1\n', 'Line 2\n', 'Line 3']

There is no canonical answer, since XML fundamentally has no null concept. But I assume you want Xml/Object mapping (since object graphs have nulls); so the answer for you is "whatever your tool uses". If you write handling, that means whatever you prefer. For tools that use XML Schema, xsi:nil is the way to go. For most mappers, omitting matching element/attribute is the way to do it.

I thought this is a simple example might someone get it easier,

        DECLARE @TB1 TABLE
        (
            No Int
            ,Name NVarchar(50)
        )

        DECLARE @TB2 TABLE
        (
            No Int
            ,Name NVarchar(50)
        )

        INSERT INTO @TB1 VALUES(1,'asdf');
        INSERT INTO @TB1 VALUES(2,'awerq');


        INSERT INTO @TB2 VALUES(1,';oiup');
        INSERT INTO @TB2 VALUES(2,'lkjhj');

        SELECT * FROM @TB1

        UPDATE @TB1 SET Name =S.Name
        FROM @TB1 T
        INNER JOIN @TB2 S
                ON S.No = T.No

        SELECT * FROM @TB1

For IE 6, you'll want to equal colspan to the number of columns in your table. If you have 5 columns, then you'll want: colspan="5".

The reason is that IE handles colspans differently, it uses the HTML 3.2 specification:

IE implements the HTML 3.2 definition, it sets colspan=0 as colspan=1.

The bug is well documented.

No.

What are you trying to do?

workaround:

int main(void)
{
  struct foo
  {
    void operator()() { int a = 1; }
  };

  foo b;
  b(); // call the operator()

}

Look up the new HTML5 Input Types. These instruct browsers to perform client-side filtering of data, but the implementation is incomplete across different browsers. The pattern attribute will do regex-style filtering, but, again, browsers don't fully (or at all) support it.

However, these won't block the input itself, it will simply prevent submitting the form with the invalid data. You'll still need to trap the onkeydown event to block key input before it displays on the screen.

copy2(src,dst) is often more useful than copyfile(src,dst) because:

• it allows dst to be a directory (instead of the complete target filename), in which case the basename of src is used for creating the new file;
• it preserves the original modification and access info (mtime and atime) in the file metadata (however, this comes with a slight overhead).

Here is a short example:

import shutil
shutil.copy2('/src/dir/file.ext', '/dst/dir/newname.ext') # complete target filename given
shutil.copy2('/src/file.ext', '/dst/dir') # target filename is /dst/dir/file.ext

If you know the position, why not just get the index from that?

Then use .loc:

df.loc[index, 'COL_NAME'] = x

Just had this issue, it happened because I'd first added the build file to the ant-view when the default JRE was 1.6.

There was no project-specific JRE and I changed the default to 1.5, even eclipse was running in 1.5, and JAVA_HOME was 1.5 too. Running the ant target from the command line used JRE 1.5, but within eclipse it still used 1.6.

I had to right-click the ant target, select Run As... and change the JRE under the JRE tab. This setting is remembered for subsequent runs.

2019: Use the 'useCallback' react hook

After trying many different approaches, I found using useCallback to be the simplest and most efficient at solving the multiple calls problem of using debounce within an onChange event.

As per the Hooks API documentation,

useCallback returns a memorized version of the callback that only changes if one of the dependencies has changed.

Passing an empty array as a dependency makes sure the callback is called only once. Here's a simple implementation :

import React, { useCallback } from "react";
import { debounce } from "lodash";

const handler = useCallback(debounce(someFunction, 2000), []);

const onChange = (event) => {
    // perform any event related action here

    handler();
 };

Hope this helps!

TLDR: use theString = theString.replace("\\", "\\\\"); instead.

Problem

replaceAll(target, replacement) uses regular expression (regex) syntax for target and partially for replacement.

Problem is that \ is special character in regex (it can be used like \d to represents digit) and in String literal (it can be used like "\n" to represent line separator or \" to escape double quote symbol which normally would represent end of string literal).

In both these cases to create \ symbol we can escape it (make it literal instead of special character) by placing additional \ before it (like we escape " in string literals via \").

So to target regex representing \ symbol will need to hold \\, and string literal representing such text will need to look like "\\\\".

So we escaped \ twice:

• once in regex \\
• once in String literal "\\\\" (each \ is represented as "\\").

In case of replacement \ is also special there. It allows us to escape other special character $ which via $x notation, allows us to use portion of data matched by regex and held by capturing group indexed as x, like "012".replaceAll("(\\d)", "$1$1") will match each digit, place it in capturing group 1 and $1$1 will replace it with its two copies (it will duplicate it) resulting in "001122".

So again, to let replacement represent \ literal we need to escape it with additional \ which means that:

• replacement must hold two backslash characters \\
• and String literal which represents \\ looks like "\\\\"

BUT since we want replacement to hold two backslashes we will need "\\\\\\\\" (each \ represented by one "\\\\").

So version with replaceAll can look like

replaceAll("\\\\", "\\\\\\\\");

Easier way

To make out life easier Java provides tools to automatically escape text into target and replacement parts. So now we can focus only on strings, and forget about regex syntax:

replaceAll(Pattern.quote(target), Matcher.quoteReplacement(replacement))

which in our case can look like

replaceAll(Pattern.quote("\\"), Matcher.quoteReplacement("\\\\"))

Even better

If we don't really need regex syntax support lets not involve replaceAll at all. Instead lets use replace. Both methods will replace all targets, but replace doesn't involve regex syntax. So you could simply write

theString = theString.replace("\\", "\\\\");

• Relationships are named and classified by their cardinality (i.e. number of elements of the set).
• Symbols which appears closes to the entity is Maximum cardinality and the other one is Minimum cardinality.
• Entity relation, shows end of the relationship line as follows:

Use Remove()...

string foo = "1234567890";
int trimLength = 5;

if (foo.Length > trimLength) foo = foo.Remove(trimLength);

// foo is now "12345"

To convert this bytesarray directly to json, you could first convert the bytesarray to a string with decode(), utf-8 is standard. Change the quotation markers.. The last step is to remove the " from the dumped string, to change the json object from string to list.

dumps(s.decode()).replace("'", '"')[1:-1]

There are three good answers to this question.

• Use the unsrt bibliography style, if you're happy with its formatting otherwise
• Use the makebst (link) tool to design your own bibliography style

And my personal recommendation:

• Use the biblatex package (link). It's the most complete and flexible bibliography tool in the LaTeX world.

Using biblatex, you'd write something like

\documentclass[12pt]{article}
\usepackage[sorting=none]{biblatex}
\bibliography{journals,phd-references} % Where journals.bib and phd-references.bib are BibTeX databases
\begin{document}
\cite{robertson2007}
\cite{earnshaw1842}
\printbibliography
\end{document}

Well, I am a bit curious, so I just tested the three myself right after asking the question ;-)

Ok, this is not a very serious review, but here is what I can say:

I tried the tools with the default settings (it's important because you can pretty much choose your check rules) on the following script:

#!/usr/local/bin/python
# by Daniel Rosengren modified by e-satis

import sys, time
stdout = sys.stdout

BAILOUT = 16
MAX_ITERATIONS = 1000

class Iterator(object) :

    def __init__(self):

        print 'Rendering...'
        for y in xrange(-39, 39):
            stdout.write('\n')
            for x in xrange(-39, 39):
                if self.mandelbrot(x/40.0, y/40.0) :
                    stdout.write(' ')
                else:
                    stdout.write('*')


    def mandelbrot(self, x, y):
        cr = y - 0.5
        ci = x
        zi = 0.0
        zr = 0.0

        for i in xrange(MAX_ITERATIONS) :
            temp = zr * zi
            zr2 = zr * zr
            zi2 = zi * zi
            zr = zr2 - zi2 + cr
            zi = temp + temp + ci

            if zi2 + zr2 > BAILOUT:
                return i

        return 0

t = time.time()
Iterator()
print '\nPython Elapsed %.02f' % (time.time() - t)

As a result:

• PyChecker is troublesome because it compiles the module to analyze it. If you don't want your code to run (e.g, it performs a SQL query), that's bad.
• PyFlakes is supposed to be light. Indeed, it decided that the code was perfect. I am looking for something quite severe so I don't think I'll go for it.
• PyLint has been very talkative and rated the code 3/10 (OMG, I'm a dirty coder !).

Strong points of PyLint:

• Very descriptive and accurate report.
• Detect some code smells. Here it told me to drop my class to write something with functions because the OO approach was useless in this specific case. Something I knew, but never expected a computer to tell me :-p
• The fully corrected code run faster (no class, no reference binding...).
• Made by a French team. OK, it's not a plus for everybody, but I like it ;-)

Cons of Pylint:

• Some rules are really strict. I know that you can change it and that the default is to match PEP8, but is it such a crime to write 'for x in seq'? Apparently yes because you can't write a variable name with less than 3 letters. I will change that.
• Very very talkative. Be ready to use your eyes.

Thanks to Rudiger Wolf, I discovered pep8 that does exactly what its name suggests: matching PEP8. It has found several syntax no-nos that Pylint did not. But Pylint found stuff that was not specifically linked to PEP8 but interesting. Both tools are interesting and complementary.

Eventually I will use both since there are really easy to install (via packages or setuptools) and the output text is so easy to chain.

To give you a little idea of their output:

pep8:
