My case, the server was encrypting with padding disabled. But the client was trying to decrypt with the padding enabled.

While using EVP_CIPHER*, by default the padding is enabled. To disable explicitly we need to do

EVP_CIPHER_CTX_set_padding(context, 0);

So non matching padding options can be one reason.

[Posted on behalf of fossuser] Thanks to "mu is too short" I was able to fix the bug. Here is my working code has been edited in for those looking for a nice example (since I couldn't find any others online).

Yes, there is better. Check the stat or the fstat function

Change event on the select box to fire and once it does then just pull the id attribute of the selected option :-

$("#type").change(function(){
  var id = $(this).find("option:selected").attr("id");

  switch (id){
    case "trade_buy_max":
      // do something here
      break;
  }
});

The problem is even if you create a proxy or load the content and inject it as if it's local, any scripts that that content defines will be loaded from the other domain and cause cross-domain problems.

You can use OutputDebugString. OutputDebugString is a macro that depending on your build options either maps to OutputDebugStringA(char const*) or OutputDebugStringW(wchar_t const*). In the later case you will have to supply a wide character string to the function. To create a wide character literal you can use the L prefix:

OutputDebugStringW(L"My output string.");

Normally you will use the macro version together with the _T macro like this:

OutputDebugString(_T("My output string."));

If you project is configured to build for UNICODE it will expand into:

OutputDebugStringW(L"My output string.");

If you are not building for UNICODE it will expand into:

OutputDebugStringA("My output string.");

A lot of explanations are already present to explain how it happens and how to fix it, but you should also follow best practices to avoid NullPointerExceptions at all.

I would add, very important, make a good use of the final modifier. Using the "final" modifier whenever applicable in Java

Summary:

1. Use the final modifier to enforce good initialization.
2. Avoid returning null in methods, for example returning empty collections when applicable.
3. Use annotations @NotNull and @Nullable
4. Fail fast and use asserts to avoid propagation of null objects through the whole application when they shouldn't be null.
5. Use equals with a known object first: if("knownObject".equals(unknownObject)
6. Prefer valueOf() over toString().
7. Use null safe StringUtils methods StringUtils.isEmpty(null).
8. Use Java 8 Optional as return value in methods, Optional class provide a solution for representing optional values instead of null references.

Use the C Standard Library function getchar() instead as getch() is not a standard function, being provided by Borland TURBO C for MS-DOS/Windows only.

printf("Let the Battle Begin!\n");
printf("Press Any Key to Continue\n");  
getchar();    
 

Here, getchar() expects you to press the return key so the printf statement should be press ENTER to continue. Even if you press another key, you still need to press ENTER:

printf("Let the Battle Begin!\n");
printf("Press ENTER key to Continue\n");  
getchar();    

If you are using Windows then you can use getch()

printf("Let the Battle Begin!\n");
printf("Press Any Key to Continue\n");
getch();   
//if you press any character it will continue ,  
//but this is not a standard c function.

char ch;
printf("Let the Battle Begin!\n");
printf("Press ENTER key to Continue\n");    
//here also if you press any other key will wait till pressing ENTER
scanf("%c",&ch); //works as getchar() but here extra variable is required.      

My JavaDude Bean Annotation Processor generates code to do this.

http://javadude.googlecode.com

For example:

@Bean(
  createPropertyMap=true,
  properties={
    @Property(name="name"),
    @Property(name="phone", bound=true),
    @Property(name="friend", type=Person.class, kind=PropertyKind.LIST)
  }
)
public class Person extends PersonGen {}

The above generates superclass PersonGen that includes a createPropertyMap() method that generates a Map for all properties defined using @Bean.

(Note that I'm changing the API slightly for the next version -- the annotation attribute will be defineCreatePropertyMap=true)

While padding programmatically, convert to density related values by converting pixel to Dp.

Another option is doing the following:

public class UserList extends List<User>{

}

public <T> T magicalListGetter(Class<T> clazz) {
    List<?> list = doMagicalVooDooHere();
    return (T)list;
}

List<User> users = magicalListGetter(UserList.class);

`

For me it work fine

&:not(:last-child){
            text-transform: uppercase;
        }

//  Hey, your shoe's untied!

Followed by some dubious code, and within that code,

//  Keep looking!  I think it was the other shoe!

Finally,

//  How strange -- I must be seeing things.  Anyhow, I'm going to go take a shower, now...

with pygame:

dy = p1.y - p2.y
dX = p2.x - p1.x

rads = atan2(dy,dx)
degs = degrees(rads)
if degs < 0 :
   degs +=90

it work for me

To get this i tried following code :

  protected T GetObject<T>()
    {
        T obj = default(T);
        obj =Activator.CreateInstance<T>();
        return obj ;
    }

if (!$("input[name='html_elements']:checked").val()) {
   alert('Nothing is checked!');
}
else {
  alert('One of the radio buttons is checked!');
}

Try to use this

$xml = ... // Xml file data

// first approach
$Json = json_encode(simplexml_load_string($xml));

---------------- OR -----------------------

// second approach
$Json = json_encode(simplexml_load_string($xml, "SimpleXMLElement", LIBXML_NOCDATA));

echo $Json;

@Xander's solution works, but does not persist after a reboot.

I found that I had to change listen.mode to 0660 in /etc/php5/fpm/pool.d/www.conf.

Sample from www.conf:

; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions. 
; Default Values: user and group are set as the running user
;                 mode is set to 0660
;listen.owner = www-data
;listen.group = www-data
;listen.mode = 0660

Edit: Per @Chris Burgess, I've changed this to the more secure method.

I removed the comment for listen.mode, .group and .owner:

listen.owner = www-data
listen.group = www-data
listen.mode = 0660

/var/run Only holds information about the running system since last boot, e.g., currently logged-in users and running daemons. (http://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard#Directory_structure).

Side note:

My php5-fpm -v Reports: PHP 5.4.28-1+deb.sury.org~precise+1. The issue did happen after a recent update as well.

To complement the previous answers, after you edit your CSS file, you just need to edit CAROUSEL.TRANSITION_DURATION (in bootstrap.js) or c.TRANSITION_DURATION (if you use bootstrap.min.js) and to change the value inside it (600 for default). The final value must be the same that you put in your CSS file (for example, 10s in CSS = 10000 in .js)

Carousel.VERSION  = '3.3.2'
Carousel.TRANSITION_DURATION = xxxxx /* Your number here*/
Carousel.DEFAULTS = {
interval: 5000 /* you could change this value too, but to add data-interval="xxxx" to your html it's fine too*/
pause: 'hover',
wrap: true,
keyboard: true
}

The String class exposes some methods to enable this, such as IndexOf and LastIndexOf, so that you may do this:

Dim myText = "abcde"
Dim dIndex = myText.IndexOf("d")
If (dIndex > -1) Then

End If

A fixed point number just means that there are a fixed number of digits after the decimal point. A floating point number allows for a varying number of digits after the decimal point.

For example, if you have a way of storing numbers that requires exactly four digits after the decimal point, then it is fixed point. Without that restriction it is floating point.

Often, when fixed point is used, the programmer actually uses an integer and then makes the assumption that some of the digits are beyond the decimal point. For example, I might want to keep two digits of precision, so a value of 100 means actually means 1.00, 101 means 1.01, 12345 means 123.45, etc.

Floating point numbers are more general purpose because they can represent very small or very large numbers in the same way, but there is a small penalty in having to have extra storage for where the decimal place goes.

Sorry, my answer is a bit too late, but it seems nobody mentioned built-in functions to reverse byte order, which in very important in terms of performance.

Most of the modern processors are little-endian, while all network protocols are big-endian. That is history and more on that you can find on Wikipedia. But that means our processors convert between little- and big-endian millions of times while we browse the Internet.

That is why most architectures have a dedicated processor instructions to facilitate this task. For x86 architectures there is BSWAP instruction, and for ARMs there is REV. This is the most efficient way to reverse byte order.

To avoid assembly in our C code, we can use built-ins instead. For GCC there is __builtin_bswap32() function and for Visual C++ there is _byteswap_ulong(). Those function will generate just one processor instruction on most architectures.

Here is an example:

#include <stdio.h>
#include <inttypes.h>

int main()
{
    uint32_t le = 0x12345678;
    uint32_t be = __builtin_bswap32(le);

    printf("Little-endian: 0x%" PRIx32 "\n", le);
    printf("Big-endian:    0x%" PRIx32 "\n", be);

    return 0;
}

Here is the output it produces:

Little-endian: 0x12345678
Big-endian:    0x78563412

And here is the disassembly (without optimization, i.e. -O0):

        uint32_t be = __builtin_bswap32(le);
   0x0000000000400535 <+15>:    mov    -0x8(%rbp),%eax
   0x0000000000400538 <+18>:    bswap  %eax
   0x000000000040053a <+20>:    mov    %eax,-0x4(%rbp)

There is just one BSWAP instruction indeed.

So, if we do care about the performance, we should use those built-in functions instead of any other method of byte reversing. Just my 2 cents.

If you run into this error in an IDE like Eclipse or IntelliJ, you may have one or more debug windows open and paused on a break-point. Terminate them.

If you are using a DbContext, use the following constructor to set the command timeout:

public class MyContext : DbContext
{
    public MyContext ()
    {
        var adapter = (IObjectContextAdapter)this;
        var objectContext = adapter.ObjectContext;
        objectContext.CommandTimeout = 1 * 60; // value in seconds
    }
}

The answer that Pablo Santa Cruz gave is correct; however, in case anybody stumbled on this page and wants more clarification, here is a detailed breakdown.

Example Tables

Suppose we have the following tables:

-- t1
id  name
1   Tim
2   Marta

-- t2
id  name
1   Tim
3   Katarina

Inner Joins

An inner join, like this:

SELECT *
FROM `t1`
INNER JOIN `t2` ON `t1`.`id` = `t2`.`id`;

Would get us only records that appear in both tables, like this:

1 Tim  1 Tim

Inner joins don't have a direction (like left or right) because they are explicitly bidirectional - we require a match on both sides.

Outer Joins

Outer joins, on the other hand, are for finding records that may not have a match in the other table. As such, you have to specify which side of the join is allowed to have a missing record.

LEFT JOIN and RIGHT JOIN are shorthand for LEFT OUTER JOIN and RIGHT OUTER JOIN; I will use their full names below to reinforce the concept of outer joins vs inner joins.

Left Outer Join

A left outer join, like this:

SELECT *
FROM `t1`
LEFT OUTER JOIN `t2` ON `t1`.`id` = `t2`.`id`;

...would get us all the records from the left table regardless of whether or not they have a match in the right table, like this:

1 Tim   1    Tim
2 Marta NULL NULL

Right Outer Join

A right outer join, like this:

SELECT *
FROM `t1`
RIGHT OUTER JOIN `t2` ON `t1`.`id` = `t2`.`id`;

...would get us all the records from the right table regardless of whether or not they have a match in the left table, like this:

1    Tim   1  Tim
NULL NULL  3  Katarina

Full Outer Join

A full outer join would give us all records from both tables, whether or not they have a match in the other table, with NULLs on both sides where there is no match. The result would look like this:

1    Tim   1    Tim
2    Marta NULL NULL
NULL NULL  3    Katarina

However, as Pablo Santa Cruz pointed out, MySQL doesn't support this. We can emulate it by doing a UNION of a left join and a right join, like this:

SELECT *
FROM `t1`
LEFT OUTER JOIN `t2` ON `t1`.`id` = `t2`.`id`

UNION

SELECT *
FROM `t1`
RIGHT OUTER JOIN `t2` ON `t1`.`id` = `t2`.`id`;

You can think of a UNION as meaning "run both of these queries, then stack the results on top of each other"; some of the rows will come from the first query and some from the second.

It should be noted that a UNION in MySQL will eliminate exact duplicates: Tim would appear in both of the queries here, but the result of the UNION only lists him once. My database guru colleague feels that this behavior should not be relied upon. So to be more explicit about it, we could add a WHERE clause to the second query:

SELECT *
FROM `t1`
LEFT OUTER JOIN `t2` ON `t1`.`id` = `t2`.`id`

UNION

SELECT *
FROM `t1`
RIGHT OUTER JOIN `t2` ON `t1`.`id` = `t2`.`id`
WHERE `t1`.`id` IS NULL;

On the other hand, if you wanted to see duplicates for some reason, you could use UNION ALL.

I fixed this by making sure that that OpenSSL was installed on my machine and then adding this to my php.ini:

openssl.cafile=/usr/local/etc/openssl/cert.pem

Try something like this:

awk -vc=1 'NR%1000000==0{++c}{print $0 > c".txt"}' Datafile.txt

for filename in *.txt; do mv "$filename" "Prefix_$filename"; done;

It's a warning, not an error. It occurs because fsevents is an optional dependency, used only when project is run on macOS environment (the package provides 'Native Access to Mac OS-X FSEvents').

And since you're running your project on Windows, fsevents is skipped as irrelevant.

There is a PR to fix this behaviour here: https://github.com/npm/cli/pull/169

Example:

  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build --prod",
    "build_c": "ng build --prod && del \"../../server/front-end/*.*\" /s /q & xcopy /s dist \"../../server/front-end\"",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },

As you can see, the script "build_c" is building the angular application, then deletes all old files from a directory, then finally copies the result build files.

In the past, I've solved this kind of problem with StringTemplate and Groovy Templates.

Ultimately, the decision of using a templating engine or not should be based on the following factors:

• Will you have many of these templates in the application?
• Do you need the ability to modify the templates without restarting the application?
• Who will be maintaining these templates? A Java programmer or a business analyst involved on the project?
• Will you need to the ability to put logic in your templates, like conditional text based on values in the variables?
• Will you need the ability to include other templates in a template?

If any of the above applies to your project, I would consider using a templating engine, most of which provide this functionality, and more.

There are multiple easy ways.

1. Just touch web.xml of any webapp.

   touch /usr/share/tomcat/webapps/<WEBAPP-NAME>/WEB-INF/web.xml
   

You can also update a particular jar file in WEB-INF/lib and then touch web.xml, rather than building whole war file and deploying it again.

2. Delete webapps/YOUR_WEB_APP directory, Tomcat will start deploying war within 5 seconds (assuming your war file still exists in webapps folder).

3. Generally overwriting war file with new version gets redeployed by tomcat automatically. If not, you can touch web.xml as explained above.

4. Copy over an already exploded "directory" to your webapps folder

Simple, create multiple accordian div each representating one anchor tag like:

<div>
<div class="accordion">
<a href = "#">First heading</a>
</div>
<div class="accordion">
<a href = "#">First heading</a>
</div>
</div>

It adds up some markup. But works like a pro...

I had similar problem and i solved it following way.

Solve as follows:

Function prototype declarations and global variable should be in test.h file and you can not initialize global variable in header file.

Function definition and use of global variable in test.c file

if you initialize global variables in header it will have following error

multiple definition of `_ test'| obj\Debug\main.o:path\test.c|1|first defined here|

Just declarations of global variables in Header file no initialization should work.

Hope it helps

Cheers

This worked for me:

BufferedImage bufImgs = ImageIO.read(new File("c:\\adi.bmp"));    
double[][] data = new double[][];
bufImgs.getData().getPixels(0,0,bufImgs.getWidth(),bufImgs.getHeight(),data[i]);    

fiddle

var $select = $('#down'); 
$select.find('option').remove();  
$.each(temp,function(key, value) 
{
    $select.append('<option value=' + key + '>' + value + '</option>');
});

Iterator through keySet will give you keys. You should use entrySet if you want to iterate entries.

HashMap hm = new HashMap();

hm.put(0, "zero");
hm.put(1, "one");

Iterator iter = (Iterator) hm.entrySet().iterator();

while(iter.hasNext()) {

    Map.Entry entry = (Map.Entry) iter.next();
    System.out.println(entry.getKey() + " - " + entry.getValue());

}

I've just noticed that the answer that I upvoted and commented on is ambiguous. So the following is exactly what worked for me. I'm currently on Moment 2.26.0 and TS 3.8.3:

In code:

import moment from 'moment';

In TS config:

{
  "compilerOptions": {
    "esModuleInterop": true,
    ...
  }
}

I am building for both CommonJS and EMS so this config is imported into other config files.

The insight comes from this answer which relates to using Express. I figured it was worth adding here though, to help anyone who searches in relation to Moment.js, rather than something more general.

You can use ISNULL and check the answer against the known output:

SELECT case when ISNULL(col1, '') = '' then '' else col1 END AS COL1 FROM TEST

Remember to look if your column can be null. You can do that using

mysql> desc my_table;

If your column cannot be null, when you set the value to null it will be the cast value to it.

Here a example

mysql> create table example ( age int not null, name varchar(100) not null );
mysql> insert into example values ( null, "without num" ), ( 2 , null );
mysql> select * from example;
+-----+-------------+
| age | name        |
+-----+-------------+
|   0 | without num |
|   2 |             |
+-----+-------------+
2 rows in set (0.00 sec)

mysql> select * from example where age is null or name is null;
Empty set (0.00 sec)

Start from index.html remove all # from <a href="#/aboutus">About Us</a> so it must look like <a href="/aboutus">About Us</a>.Now in head tag of index.html write <base href="/"> just after last meta tag.

Now in your routing js inject $locationProvider and write $locatonProvider.html5Mode(true); Something Like This:-

app.config(function ($routeProvider, $locationProvider) {
    $routeProvider
        .when("/home", {
            templateUrl: "Templates/home.html",
            controller: "homeController"
        })
            .when("/aboutus",{templateUrl:"Templates/aboutus.html"})
            .when("/courses", {
                templateUrl: "Templates/courses.html",
                controller: "coursesController"
            })
            .when("/students", {
                templateUrl: "Templates/students.html",
                controller: "studentsController"
            })
        $locationProvider.html5Mode(true);
    });

What Joomla! does is defining a Constant in a root file and checking if the same is defined in the included files.

defined('_JEXEC') or die('Restricted access');

or else

one can keep all files outside the reach of an http request by placing them outside the webroot directory as most frameworks like CodeIgniter recommend.

or even by placing an .htaccess file within the include folder and writing rules, you can prevent direct access.

Let us maintain an array where the ith element is the smallest possible number with which a i sized sub sequence can end.

On purpose I am avoiding further details as the top voted answer already explains it, but this technique eventually leads to a neat implementation using the set data structure (at least in c++).

Here is the implementation in c++ (assuming strictly increasing longest sub sequence size is required)

#include <bits/stdc++.h> // gcc supported header to include (almost) everything
using namespace std;
typedef long long ll;

int main()
{
  ll n;
  cin >> n;
  ll arr[n];
  set<ll> S;

  for(ll i=0; i<n; i++)
  {
    cin >> arr[i];
    auto it = S.lower_bound(arr[i]);
    if(it != S.end())
      S.erase(it);
    S.insert(arr[i]);
  }

  cout << S.size() << endl; // Size of the set is the required answer

  return 0;
}

The issue is that the URL is being blocked from being created by Windows.

Steps to fix: Run command prompt as an administrator. Add the URL to the ACL

netsh http add urlacl url=http://+:8000/ServiceModelSamples/Service user=mylocaluser

First, to address your first inquiry:

When you see this in .h file:

#ifndef FILE_H
#define FILE_H

/* ... Declarations etc here ... */

#endif

This is a preprocessor technique of preventing a header file from being included multiple times, which can be problematic for various reasons. During compilation of your project, each .cpp file (usually) is compiled. In simple terms, this means the compiler will take your .cpp file, open any files #included by it, concatenate them all into one massive text file, and then perform syntax analysis and finally it will convert it to some intermediate code, optimize/perform other tasks, and finally generate the assembly output for the target architecture. Because of this, if a file is #included multiple times under one .cpp file, the compiler will append its file contents twice, so if there are definitions within that file, you will get a compiler error telling you that you redefined a variable. When the file is processed by the preprocessor step in the compilation process, the first time its contents are reached the first two lines will check if FILE_H has been defined for the preprocessor. If not, it will define FILE_H and continue processing the code between it and the #endif directive. The next time that file's contents are seen by the preprocessor, the check against FILE_H will be false, so it will immediately scan down to the #endif and continue after it. This prevents redefinition errors.

And to address your second concern:

In C++ programming as a general practice we separate development into two file types. One is with an extension of .h and we call this a "header file." They usually provide a declaration of functions, classes, structs, global variables, typedefs, preprocessing macros and definitions, etc. Basically, they just provide you with information about your code. Then we have the .cpp extension which we call a "code file." This will provide definitions for those functions, class members, any struct members that need definitions, global variables, etc. So the .h file declares code, and the .cpp file implements that declaration. For this reason, we generally during compilation compile each .cpp file into an object and then link those objects (because you almost never see one .cpp file include another .cpp file).

How these externals are resolved is a job for the linker. When your compiler processes main.cpp, it gets declarations for the code in class.cpp by including class.h. It only needs to know what these functions or variables look like (which is what a declaration gives you). So it compiles your main.cpp file into some object file (call it main.obj). Similarly, class.cpp is compiled into a class.obj file. To produce the final executable, a linker is invoked to link those two object files together. For any unresolved external variables or functions, the compiler will place a stub where the access happens. The linker will then take this stub and look for the code or variable in another listed object file, and if it's found, it combines the code from the two object files into an output file and replaces the stub with the final location of the function or variable. This way, your code in main.cpp can call functions and use variables in class.cpp IF AND ONLY IF THEY ARE DECLARED IN class.h.

I hope this was helpful.

There is no difference between the two, one is just a shorthand for the second.

The v- prefix serves as a visual cue for identifying Vue-specific attributes in your templates. This is useful when you are using Vue.js to apply dynamic behavior to some existing markup, but can feel verbose for some frequently used directives. At the same time, the need for the v- prefix becomes less important when you are building an SPA where Vue.js manages every template.

<!-- full syntax -->
<a v-on:click="doSomething"></a>
<!-- shorthand -->
<a @click="doSomething"></a>

Try updating your Ruby on Rails version to v3.0.5:

gem install rails --version 3.0.5

or v2.3.11:

gem install rails --version 2.3.11

If this isn't a new project you'll have to upgrade your application accordingly. If it was a new project, just delete the directory you created it in and create a new project again.

You can use rails dbconsole to view the database that your rails application is using. It's alternative answer rails db. Both commands will direct you the command line interface and will allow you to use that database query syntax.

There is also EXISTS:

SELECT count(*) AS post_ct
FROM   posts p
WHERE  EXISTS (SELECT FROM votes v WHERE v.post_id = p.id);

In Postgres and with multiple entries on the n-side like you probably have, it's generally faster than count(DISTINCT post_id):

SELECT count(DISTINCT p.id) AS post_ct
FROM   posts p
JOIN   votes v ON v.post_id = p.id;

The more rows per post there are in votes, the bigger the difference in performance. Test with EXPLAIN ANALYZE.

count(DISTINCT post_id) has to read all rows, sort or hash them, and then only consider the first per identical set. EXISTS will only scan votes (or, preferably, an index on post_id) until the first match is found.

If every post_id in votes is guaranteed to be present in the table posts (referential integrity enforced with a foreign key constraint), this short form is equivalent to the longer form:

SELECT count(DISTINCT post_id) AS post_ct
FROM   votes;

May actually be faster than the EXISTS query with no or few entries per post.

The query you had works in simpler form, too:

SELECT count(*) AS post_ct
FROM  (
    SELECT FROM posts 
    JOIN   votes ON votes.post_id = posts.id 
    GROUP  BY posts.id
    ) sub;

Benchmark

To verify my claims I ran a benchmark on my test server with limited resources. All in a separate schema:

Test setup

Fake a typical post / vote situation:

CREATE SCHEMA y;
SET search_path = y;

CREATE TABLE posts (
  id   int PRIMARY KEY
, post text
);

INSERT INTO posts
SELECT g, repeat(chr(g%100 + 32), (random()* 500)::int)  -- random text
FROM   generate_series(1,10000) g;

DELETE FROM posts WHERE random() > 0.9;  -- create ~ 10 % dead tuples

CREATE TABLE votes (
  vote_id serial PRIMARY KEY
, post_id int REFERENCES posts(id)
, up_down bool
);

INSERT INTO votes (post_id, up_down)
SELECT g.* 
FROM  (
   SELECT ((random()* 21)^3)::int + 1111 AS post_id  -- uneven distribution
        , random()::int::bool AS up_down
   FROM   generate_series(1,70000)
   ) g
JOIN   posts p ON p.id = g.post_id;

All of the following queries returned the same result (8093 of 9107 posts had votes).
I ran 4 tests with EXPLAIN ANALYZE ant took the best of five on Postgres 9.1.4 with each of the three queries and appended the resulting total runtimes.

1. As is.

2. After ..

   ANALYZE posts;
   ANALYZE votes;
   

3. After ..

   CREATE INDEX foo on votes(post_id);
   

4. After ..

   VACUUM FULL ANALYZE posts;
   CLUSTER votes using foo;
   

count(*) ... WHERE EXISTS

1. 253 ms
2. 220 ms
3. 85 ms -- winner (seq scan on posts, index scan on votes, nested loop)
4. 85 ms

count(DISTINCT x) - long form with join

1. 354 ms
2. 358 ms
3. 373 ms -- (index scan on posts, index scan on votes, merge join)
4. 330 ms

count(DISTINCT x) - short form without join

1. 164 ms
2. 164 ms
3. 164 ms -- (always seq scan)
4. 142 ms

Best time for original query in question:

• 353 ms

For simplified version:

• 348 ms

@wildplasser's query with a CTE uses the same plan as the long form (index scan on posts, index scan on votes, merge join) plus a little overhead for the CTE. Best time:

• 366 ms

Index-only scans in the upcoming PostgreSQL 9.2 can improve the result for each of these queries, most of all for EXISTS.

Related, more detailed benchmark for Postgres 9.5 (actually retrieving distinct rows, not just counting):

• Select first row in each GROUP BY group?

The problem is that System. currentTimeMillis(); returns the number of milliseconds from 1970-01-01T00:00:00Z, but new Date() gives the current local time. Adding the ZONE_OFFSET and DST_OFFSET from the Calendar class gives you the time in UTC.

Calendar rightNow = Calendar.getInstance();

// offset to add since we're not UTC

long offset = rightNow.get(Calendar.ZONE_OFFSET) +
    rightNow.get(Calendar.DST_OFFSET);

long sinceMidnight = (rightNow.getTimeInMillis() + offset) %
    (24 * 60 * 60 * 1000);

System.out.println(sinceMidnight + " milliseconds since midnight");

This command will "dry run" delete all remote (origin) merged branches, apart from master. You can change that, or, add additional branches after master: grep -v for-example-your-branch-here |

git branch -r --merged | 
  grep origin | 
  grep -v '>' | 
  grep -v master | 
  xargs -L1 | 
  awk '{sub(/origin\//,"");print}'| 
  xargs git push origin --delete --dry-run

If it looks good, remove the --dry-run. Additionally, you may like to test this on a fork first.

To have font variation working correctly, I had to reverse the order of @font-face in CSS.

@font-face {
    font-family: "DejaVuMono";
    src: url("styles/DejaVuSansMono-BoldOblique.ttf");
    font-weight: bold;
    font-style: italic, oblique;
}   
@font-face {
    font-family: "DejaVuMono";
    src: url("styles/DejaVuSansMono-Oblique.ttf");
    font-style: italic, oblique;
}
@font-face {
    font-family: "DejaVuMono";
    src: url("styles/DejaVuSansMono-Bold.ttf");
    font-weight: bold;
}
 @font-face {
    font-family: "DejaVuMono";
    src: url("styles/DejaVuSansMono.ttf");
}

The following works for me:

SSHPASS='myPassword'
/usr/bin/rsync -a -r -p -o -g --progress --modify-window=1 --exclude /folderOne -s -u --rsh="/usr/bin/sshpass -p $SSHPASS ssh -o StrictHostKeyChecking=no -l root"  source-path  myDomain:dest-path  >&2

I had to install sshpass

Have a look at iconv() or mb_convert_encoding(). Just by the way: why don't utf8_encode() and utf8_decode() work for you?

utf8_decode — Converts a string with ISO-8859-1 characters encoded with UTF-8 to single-byte ISO-8859-1

utf8_encode — Encodes an ISO-8859-1 string to UTF-8

So essentially

$utf8 = 'ÄÖÜ'; // file must be UTF-8 encoded
$iso88591_1 = utf8_decode($utf8);
$iso88591_2 = iconv('UTF-8', 'ISO-8859-1', $utf8);
$iso88591_2 = mb_convert_encoding($utf8, 'ISO-8859-1', 'UTF-8');

$iso88591 = 'ÄÖÜ'; // file must be ISO-8859-1 encoded
$utf8_1 = utf8_encode($iso88591);
$utf8_2 = iconv('ISO-8859-1', 'UTF-8', $iso88591);
$utf8_2 = mb_convert_encoding($iso88591, 'UTF-8', 'ISO-8859-1');

all should do the same - with utf8_en/decode() requiring no special extension, mb_convert_encoding() requiring ext/mbstring and iconv() requiring ext/iconv.

The ?: Operator returns one of two values depending on the value of a Boolean expression.

This is how I did it. You don't need to delete Java 9 or newer version.

Step 1: Install Java 8

You can download Java 8 from here: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Step 2: After installation of Java 8. Confirm installation of all versions.Type the following command in your terminal.

/usr/libexec/java_home -V

Step 3: Edit .bash_profile

sudo nano ~/.bash_profile

Step 4: Add 1.8 as default. (Add below line to bash_profile file).

export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)

Now Press CTRL+X to exit the bash. Press 'Y' to save changes.

Step 5: Reload bash_profile

source ~/.bash_profile

Step 6: Confirm current version of Java

java -version

The following code is functionally equivalent to Jon Skeet's answer.

Tested on .NET 4.5, should work on any earlier version of LINQ.

public static IEnumerable<TSource> DistinctBy<TSource, TKey>(
  this IEnumerable<TSource> source, Func<TSource, TKey> keySelector)
{
  HashSet<TKey> seenKeys = new HashSet<TKey>();
  return source.Where(element => seenKeys.Add(keySelector(element)));
}

Incidentially, check out Jon Skeet's latest version of DistinctBy.cs on Google Code.

I am using JDK 7 for maven project and I used -Dhttps.protocols=TLSv1.2 as argument in JRE. It has allowed to download all maven repository which were failing earlier.

Call this in the project:

svn diff -r REVNO:HEAD --summarize

REVNO is the start revision number and HEAD is the end revision number. If HEAD is equal to the last revision number, it can skip it.

The command returns a list with all files that are changed/added/deleted in this revision period.

The command can be called with the URL revision parameter to check changes like this:

svn diff -r REVNO:HEAD --summarize SVN_URL

Thought I would add an answer to this one, since my problem was simple but hard to notice. In particular I had copy/pasted an existing meta-data element when creating my com.google.firebase.messaging.default_notification_icon, which used an android:value tag to specify its value. This will not work for the notification icon, and once I changed it to android:resource everything worked as expected.

LaTeX References:

Udacity's Blog has the Best LaTeX Primer I've seen: It clearly shows how to use LaTeX commands in easy to read, and easy to remember manner !! Highly recommended.

This Link has Excellent Examples showing both the code, and the rendered result !
You can use this site to quickly learn how to write LaTeX by example.

And, here is a quick Reference for LaTeX commands/symbols.

To Summarize: various ways to indicate LaTeX in Jupyter/IPython:

Examples for Markdown Cells:

inline, wrap in: $

The equation used depends on whether the the value of  
$V?max??$ is R, G, or B.  

block, wrap in: $$

$$H?  ?????0 ?+? \frac{??30(G-B)??}{Vmax-Vmin}  ??, if V?max?? = R$$

block, wrap in: \begin{equation} and \end{equation}

\begin{equation}
H? ???60 ?+? \frac{??30(B-R)??}{Vmax-Vmin}  ??, if V?max?? = G
\end{equation}

block, wrap in: \begin{align} and \end{align}

\begin{align}
H?120 ?+? \frac{??30(R-G)??}{Vmax-Vmin}  ??, if V?max?? = B
\end{align}

Examples for Code Cells:

LaTex Cell: %%latex magic command turns the entire cell into a LaTeX Cell

%%latex
\begin{align}
\nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\
\nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\
\nabla \cdot \vec{\mathbf{B}} & = 0
\end{align}

Math object to pass in a raw LaTeX string:

from IPython.display import Math
Math(r'F(k) = \int_{-\infty}^{\infty} f(x) e^{2\pi i k} dx')

Latex class. Note: you have to include the delimiters yourself. This allows you to use other LaTeX modes such as eqnarray:

from IPython.display import Latex
Latex(r"""\begin{eqnarray}
\nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\
\nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\
\nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\
\nabla \cdot \vec{\mathbf{B}} & = 0 
\end{eqnarray}""")

Docs for Raw Cells:

(sorry, no example here, just the docs)

Raw cells Raw cells provide a place in which you can write output directly. Raw cells are not evaluated by the notebook. When passed through nbconvert, raw cells arrive in the destination format unmodified. For example, this allows you to type full LaTeX into a raw cell, which will only be rendered by LaTeX after conversion by nbconvert.

Additional Documentation:

For Markdown Cells, as quoted from Jupyter Notebook docs:

Within Markdown cells, you can also include mathematics in a straightforward way, using standard LaTeX notation: $...$ for inline mathematics and $$...$$ for displayed mathematics. When the Markdown cell is executed, the LaTeX portions are automatically rendered in the HTML output as equations with high quality typography. This is made possible by MathJax, which supports a large subset of LaTeX functionality

Standard mathematics environments defined by LaTeX and AMS-LaTeX (the amsmath package) also work, such as \begin{equation}...\end{equation}, and \begin{align}...\end{align}. New LaTeX macros may be defined using standard methods, such as \newcommand, by placing them anywhere between math delimiters in a Markdown cell. These definitions are then available throughout the rest of the IPython session.

Because you send custom headers so your CORS request is not a simple request, so the browser first sends a preflight OPTIONS request to check that the server allows your request.

If you turn on CORS on the server then your code will work. You can also use JavaScript fetch instead (here)

Here is an example configuration which turns on CORS on nginx (nginx.conf file):

    if ($request_method = OPTIONS) {_x000D_
        add_header 'Access-Control-Allow-Origin' "$http_origin"; # DO NOT remove THIS LINES (doubled with outside 'if' above)_x000D_
        add_header 'Access-Control-Allow-Credentials' 'true';_x000D_

A bit of a lengthier way (if interested in it):

In your typescript code do this:

this.objectLength = Object.keys(this.previous_info).length != 0;

And in the template:

ngIf="objectLength != 0"

pip install psycopg2-binary

The psycopg2 wheel package will be renamed from release 2.8; in order to keep installing from binary please use "pip install psycopg2-binary" instead. For details see: http://initd.org/psycopg/docs/install.html#binary-install-from-pypi.

only

android:windowSoftInputMode="adjustResize"

in your activity tag inside Manifest file will do the trick

The answer from Tanoh could use some clarification. VersionCode is the equivalent of a build number. So typically an app will go through many iterations before release. Some of these iterations may make it to the Google Play store in the form of alpha, beta, and actual releases. Each successive iteration must have an incremented versionCode. However, typically you only increase the versionName when between public releases. Both numbers are significant. Your users need to know if the version they have on their phone is the latest or not (versionName) and the Play Store and CI systems such as bitrise rely on and/or update the build number (versionCode)

A dplyr solution (part of the tidyverse package set) is to use select:

select(table, "Time", "Out", "In", "Files") 

# or

select(table, Time, Out, In, Files)

In javascript there are trues and truthys. When something is true it is obviously true or false. When something is truthy it may or may not be a boolean, but the "cast" value of is a boolean.

Examples.

true == true; // (true) true
1 == true; // (true) truthy
"hello" == true;  // (true) truthy
[1, 2, 3] == true; // (true) truthy
[] == false; // (true) truthy
false == false; // (true) true
0 == false; // (true) truthy
"" == false; // (true) truthy
undefined == false; // (true) truthy
null == false; // (true) truthy

This can make things simpler if you want to check if a string is set or an array has any values.

var users = [];

if(users) {
  // this array is populated. do something with the array
}

var name = "";

if(!name) {
  // you forgot to enter your name!
}

And as stated. expect(something).toBe(true) and expect(something).toBeTrue() is the same. But expect(something).toBeTruthy() is not the same as either of those.

http://api.jquery.com/jQuery.ajax/

jQuery.ajax()

Description: Perform an asynchronous HTTP (Ajax) request.

The full monty, lets you make any kind of Ajax request.

http://api.jquery.com/jQuery.get/

jQuery.get()

Description: Load data from the server using a HTTP GET request.

Only lets you make HTTP GET requests, requires a little less configuration.

http://api.jquery.com/load/

.load()

Description: Load data from the server and place the returned HTML into the matched element.

Specialized to get data and inject it into an element.

Here is the best method that I've found: First, set your projects output type to "Windows Application", then P/Invoke AllocConsole to create a console window.

internal static class NativeMethods
{
    [DllImport("kernel32.dll")]
    internal static extern Boolean AllocConsole();
}

static class Program
{

    static void Main(string[] args) {
        if (args.Length == 0) {
            // run as windows app
            Application.EnableVisualStyles();
            Application.Run(new Form1()); 
        } else {
            // run as console app
            NativeMethods.AllocConsole();
            Console.WriteLine("Hello World");
            Console.ReadLine();
        }
    }

}

This solves the problem on my end.

var files = sftp.ListDirectory(remoteVendorDirectory).Where(f => !f.IsDirectory);

foreach (var file in files)
{
    var filename = $"{LocalDirectory}/{file.Name}";
    if (!File.Exists(filename))
    {
        Console.WriteLine("Downloading  " + file.FullName);
        var localFile = File.OpenWrite(filename);
        sftp.DownloadFile(file.FullName, localFile);
    }
}

If you don't need the DATETIME value in the rest of your code, it'd be more efficient, simple and secure to use an UPDATE query with a sub-select, something like

UPDATE products SET t=(SELECT f FROM products WHERE id=17) WHERE id=42;

or in case it's in the same row in a single table, just

UPDATE products SET t=f WHERE id=42;

C# is a programming language, .NET is the framework that the language is built on.

Although the existing answers are valid approaches , they are antiquated . HttpClient is a modern interface for working with RESTful web services . Check the examples section of the page in the link , it has a very straightforward use case for an asynchronous HTTP GET .

using (var client = new System.Net.Http.HttpClient())
{
    return await client.GetStringAsync("https://reqres.in/api/users/3"); //uri
}

Here's a better way:

http://api.instagram.com/oembed?url=http://instagram.com/p/Y7GF-5vftL/

Render as json object and you can easily extract media id from it ---

For instance, in PHP

$api = file_get_contents("http://api.instagram.com/oembed?url=http://instagram.com/p/Y7??GF-5vftL/");      
$apiObj = json_decode($api,true);      
$media_id = $apiObj['media_id'];

For instance, in JS

You module and class AthleteList have the same name. Change:

import AthleteList

to:

from AthleteList import AthleteList

This now means that you are importing the module object and will not be able to access any module methods you have in AthleteList

The Header field of the Request is public. You may do this :

req.Header.Set("name", "value")

I had this problem as well on two different Windows computers when communicating with a Arduino Leonardo. The reliable solution was:

• Find the COM port in device manager and open the device properties.
• Open the "Port Settings" tab, and click the advanced button.
• There, uncheck the box "Use FIFO buffers (required 16550 compatible UART), and press OK.

Unfortunately, I don't know what this feature does, or how it affects this issue. After several PC restarts and a dozen device connection cycles, this is the only thing that reliably fixed the issue.

Excellent answer! I do have a small addition. Regarding this solution:

TypedQuery<CustomObject> typedQuery = em.createQuery(query , String query = "SELECT NEW CustomObject(i.firstProperty, i.secondProperty) FROM ObjectName i WHERE i.id=100";
TypedQuery<CustomObject> typedQuery = em.createQuery(query , CustomObject.class);
List<CustomObject> results = typedQuery.getResultList();CustomObject.class);

To prevent a class not found error simply insert the full package name. Assuming org.company.directory is the package name of CustomObject:

String query = "SELECT NEW org.company.directory.CustomObject(i.firstProperty, i.secondProperty) FROM ObjectName i WHERE i.id=10";
TypedQuery<CustomObject> typedQuery = em.createQuery(query , CustomObject.class);
List<CustomObject> results = typedQuery.getResultList();

There's now a C/C++ language extension from Microsoft. You can install it by going to the "quick open" thing (Ctrl+p) and typing:

ext install cpptools

You can read about it here:

https://blogs.msdn.microsoft.com/vcblog/2016/03/31/cc-extension-for-visual-studio-code/

It's very basic, as of May 2016.

Do the following steps:

1. sudo -s
2. yum install java-1.8.0-openjdk-devel
3. vi .bash_profile , and add below line into .bash_profile file and save the file.

export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.171-8.b10.el7_5.x86_64/

Note - I am using CentOS7 as OS.

SET path of JRE as well

jre is nothing but responsible for execute the program

PATH Variable value:

C:\Program Files\Java\jdk1.8.0\bin;C:\Program Files\Java\jre\bin;.;

In my case it was a component.member which was not existing e.g.

[formControl]="personId"

Adding it to the class declaration fixed it

this.personId = new FormControl(...)

You can use TEXT like this as part of a concatenation

=TEXT(A1,"dd-mmm-yy") & " other string"

rsync is work!

#file:
rsync -aqz _vimrc ~/.vimrc

#directory:
rsync -aqz _vim/ ~/.vim

You can delete files in PHP using the unlink() function.

unlink('path/to/file.jpg');

_{Note: This is not a duplicate, because the OP is aware that the image from cv2.imread is in BGR format (unlike the suggested duplicate question that assumed it was RGB hence the provided answers only address that issue)}

To illustrate, I've opened up this same color JPEG image:

once using the conversion

img = cv2.imread(path)
img_gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

and another by loading it in gray scale mode

img_gray_mode = cv2.imread(path, cv2.IMREAD_GRAYSCALE)

Like you've documented, the diff between the two images is not perfectly 0, I can see diff pixels in towards the left and the bottom

I've summed up the diff too to see

import numpy as np
np.sum(diff)
# I got 6143, on a 494 x 750 image

I tried all cv2.imread() modes

Among all the IMREAD_ modes for cv2.imread(), only IMREAD_COLOR and IMREAD_ANYCOLOR can be converted using COLOR_BGR2GRAY, and both of them gave me the same diff against the image opened in IMREAD_GRAYSCALE

The difference doesn't seem that big. My guess is comes from the differences in the numeric calculations in the two methods (loading grayscale vs conversion to grayscale)

Naturally what you want to avoid is fine tuning your code on a particular version of the image just to find out it was suboptimal for images coming from a different source.

In brief, let's not mix the versions and types in the processing pipeline.

So I'd keep the image sources homogenous, e.g. if you have capturing the image from a video camera in BGR, then I'd use BGR as the source, and do the BGR to grayscale conversion cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

Vice versa if my ultimate source is grayscale then I'd open the files and the video capture in gray scale cv2.imread(path, cv2.IMREAD_GRAYSCALE)

I was searching for the same to turn bluetooth on/off, and I found this:

adb shell svc wifi enable|disable

Use these two commands (for Java 8):

sudo update-java-alternatives --set java-8-oracle
java -XshowSettings 2>&1 | grep -e 'java.home' | awk '{print "JAVA_HOME="$3}' | sed "s/\/jre//g" >> /etc/environment

VBA Function

1) .Formula = "=""THEFORMULAFUNCTION ""&(CHAR(34) & ""STUFF"" & CHAR(34))"

2) .Formula = "THEFORMULAFUNCTION ""STUFF"""

The first method uses vba to write a formula in a cell which results in the calculated value:

 THEFORMULAFUNCTION "STUFF"

The second method uses vba to write a string in a cell which results in the value:

 THEFORMULAFUNCTION "STUFF"

Excel Result/Formula

1) ="THEFORMULAFUNCTION "&(CHAR(34) & "STUFF" & CHAR(34))

2) THEFORMULAFUNCTION "STUFF"

From git stash --help

Recovering stashes that were cleared/dropped erroneously
   If you mistakenly drop or clear stashes, they cannot be recovered through the normal safety mechanisms. However, you can try the
   following incantation to get a list of stashes that are still in your repository, but not reachable any more:

       git fsck --unreachable |
       grep commit | cut -d\  -f3 |
       xargs git log --merges --no-walk --grep=WIP

This helped me better than the accepted answer with the same scenario.

Sometimes there are build path errors in .project, and you need to switch to Resource view to actually see the file that is causing the error.

In case you are using PyCharm and project stops working after rename:

1. Edit Run/Debug configuration and change environment variable DJANGO_SETTINGS_MODULE, since it includes your project name.
2. Go to Settings / Languages & Frameworks / Django and update the settings file location.

1.1) First-level cache

First-level cache always Associates with the Session object. Hibernate uses this cache by default. Here, it processes one transaction after another one, means wont process one transaction many times. Mainly it reduces the number of SQL queries it needs to generate within a given transaction. That is instead of updating after every modification done in the transaction, it updates the transaction only at the end of the transaction.

1.2) Second-level cache

Second-level cache always associates with the Session Factory object. While running the transactions, in between it loads the objects at the Session Factory level, so that those objects will be available to the entire application, not bound to single user. Since the objects are already loaded in the cache, whenever an object is returned by the query, at that time no need to go for a database transaction. In this way the second level cache works. Here we can use query level cache also.

I hope following example shed some light on constructor chaining.
my use case here for example, you are expecting user to pass a directory to your constructor, user doesn't know what directory to pass and decides to let you assign default directory. you step up and assign a default directory that you think will work.

BTW, I used LINQPad for this example in case you are wondering what *.Dump() is.
cheers

void Main()
{

    CtorChaining ctorNoparam = new CtorChaining();
    ctorNoparam.Dump();
    //Result --> BaseDir C:\Program Files (x86)\Default\ 

    CtorChaining ctorOneparam = new CtorChaining("c:\\customDir");
    ctorOneparam.Dump();    
    //Result --> BaseDir c:\customDir 
}

public class CtorChaining
{
    public string BaseDir;
    public static string DefaultDir = @"C:\Program Files (x86)\Default\";


    public CtorChaining(): this(null) {}

    public CtorChaining(string baseDir): this(baseDir, DefaultDir){}

    public CtorChaining(string baseDir, string defaultDir)
    {
        //if baseDir == null, this.BaseDir = @"C:\Program Files (x86)\Default\"
        this.BaseDir = baseDir ?? defaultDir;
    }
}

For Ubuntu 12.04 or older,

sudo apt-get install python3-pip

won't work. Instead, use:

sudo apt-get install python3-setuptools ca-certificates
sudo easy_install3 pip

I noticed some issues with this that might be useful for someone just starting, or a somewhat inexperienced user, to know. First...

CD /D "C:\Documents and Settings\%username%\Start Menu\Programs\"

two things one is that a /D after the CD may prove to be useful in making sure the directory is changed but it's not really necessary, second, if you are going to pass this from user to user you have to add, instead of your name, the code %username%, this makes the code usable on any computer, as long as they have your setup.exe file in the same location as you do on your computer. of course making sure of that is more difficult. also...

start \\filer\repo\lab\"software"\"myapp"\setup.exe

the start code here, can be set up like that, but the correct syntax is

start "\\filter\repo\lab\software\myapp\" setup.exe

This will run: setup.exe, located in: \filter\repo\lab...etc.\

I think you will probably spend most of your time trying to match words that can't possibly be built by your letter grid. So, the first thing I would do is try to speed up that step and that should get you most of the way there.

For this, I would re-express the grid as a table of possible "moves" that you index by the letter-transition you are looking at.

Start by assigning each letter a number from your entire alphabet (A=0, B=1, C=2, ... and so forth).

Let's take this example:

h b c d
e e g h
l l k l
m o f p

And for now, lets use the alphabet of the letters we have (usually you'd probably want to use the same whole alphabet every time):

 b | c | d | e | f | g | h | k | l | m |  o |  p
---+---+---+---+---+---+---+---+---+---+----+----
 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11

Then you make a 2D boolean array that tells whether you have a certain letter transition available:

     |  0  1  2  3  4  5  6  7  8  9 10 11  <- from letter
     |  b  c  d  e  f  g  h  k  l  m  o  p
-----+--------------------------------------
 0 b |     T     T     T  T     
 1 c |  T     T  T     T  T
 2 d |     T           T  T
 3 e |  T  T     T     T  T  T  T
 4 f |                       T  T     T  T
 5 g |  T  T  T  T        T  T  T
 6 h |  T  T  T  T     T     T  T
 7 k |           T  T  T  T     T     T  T
 8 l |           T  T  T  T  T  T  T  T  T
 9 m |                          T     T
10 o |              T        T  T  T
11 p |              T        T  T
 ^
 to letter

Now go through your word list and convert the words to transitions:

hello (6, 3, 8, 8, 10):
6 -> 3, 3 -> 8, 8 -> 8, 8 -> 10

Then check if these transitions are allowed by looking them up in your table:

[6][ 3] : T
[3][ 8] : T
[8][ 8] : T
[8][10] : T

If they are all allowed, there's a chance that this word might be found.

For example the word "helmet" can be ruled out on the 4th transition (m to e: helMEt), since that entry in your table is false.

And the word hamster can be ruled out, since the first (h to a) transition is not allowed (doesn't even exist in your table).

Now, for the probably very few remaining words that you didn't eliminate, try to actually find them in the grid the way you're doing it now or as suggested in some of the other answers here. This is to avoid false positives that result from jumps between identical letters in your grid. For example the word "help" is allowed by the table, but not by the grid.

Some further performance improvement tips on this idea:

1. Instead of using a 2D array, use a 1D array and simply compute the index of the second letter yourself. So, instead of a 12x12 array like above, make a 1D array of length 144. If you then always use the same alphabet (i.e. a 26x26 = 676x1 array for the standard english alphabet), even if not all letters show up in your grid, you can pre-compute the indices into this 1D array that you need to test to match your dictionary words. For example, the indices for 'hello' in the example above would be

   hello (6, 3, 8, 8, 10):
   42 (from 6 + 3x12), 99, 104, 128
   -> "hello" will be stored as 42, 99, 104, 128 in the dictionary
   

2. Extend the idea to a 3D table (expressed as a 1D array), i.e. all allowed 3-letter combinations. That way you can eliminate even more words immediately and you reduce the number of array lookups for each word by 1: For 'hello', you only need 3 array lookups: hel, ell, llo. It will be very quick to build this table, by the way, as there are only 400 possible 3-letter-moves in your grid.

3. Pre-compute the indices of the moves in your grid that you need to include in your table. For the example above, you need to set the following entries to 'True':

   (0,0) (0,1) -> here: h, b : [6][0]
   (0,0) (1,0) -> here: h, e : [6][3]
   (0,0) (1,1) -> here: h, e : [6][3]
   (0,1) (0,0) -> here: b, h : [0][6]
   (0,1) (0,2) -> here: b, c : [0][1]
   .
   :
   

4. Also represent your game grid in a 1-D array with 16 entries and have the table pre-computed in 3. contain the indices into this array.

I'm sure if you use this approach you can get your code to run insanely fast, if you have the dictionary pre-computed and already loaded into memory.

BTW: Another nice thing to do, if you are building a game, is to run these sort of things immediately in the background. Start generating and solving the first game while the user is still looking at the title screen on your app and getting his finger into position to press "Play". Then generate and solve the next game as the user plays the previous one. That should give you a lot of time to run your code.

(I like this problem, so I'll probably be tempted to implement my proposal in Java sometime in the next days to see how it would actually perform... I'll post the code here once I do.)

UPDATE:

Ok, I had some time today and implemented this idea in Java:

For this I used the TWL06 Tournament Scrabble Word List, since the link in the original question no longer works. This file is 1.85MB, so it's a little bit shorter. And the buildDictionary function throws out all words with less than 3 letters.

Here are a couple of observations about the performance of this:

• It's about 10 times slower than the reported performance of Victor Nicollet's OCaml implementation. Whether this is caused by the different algorithm, the shorter dictionary he used, the fact that his code is compiled and mine runs in a Java virtual machine, or the performance of our computers (mine is an Intel Q6600 @ 2.4MHz running WinXP), I don't know. But it's much faster than the results for the other implementations quoted at the end of the original question. So, whether this algorithm is superior to the trie dictionary or not, I don't know at this point.

• The table method used in checkWordTriplets() yields a very good approximation to the actual answers. Only 1 in 3-5 words passed by it will fail the checkWords() test (See number of candidates vs. number of actual words above).

• Something you can't see above: The checkWordTriplets() function takes about 3.65ms and is therefore fully dominant in the search process. The checkWords() function takes up pretty much the remaining 0.05-0.20 ms.

• The execution time of the checkWordTriplets() function depends linearly on the dictionary size and is virtually independent of board size!

• The execution time of checkWords() depends on the board size and the number of words not ruled out by checkWordTriplets().

• The checkWords() implementation above is the dumbest first version I came up with. It is basically not optimized at all. But compared to checkWordTriplets() it is irrelevant for the total performance of the application, so I didn't worry about it. But, if the board size gets bigger, this function will get slower and slower and will eventually start to matter. Then, it would need to be optimized as well.

• One nice thing about this code is its flexibility:

  • You can easily change the board size: Update line 10 and the String array passed to initializeBoard().
  • It can support larger/different alphabets and can handle things like treating 'Qu' as one letter without any performance overhead. To do this, one would need to update line 9 and the couple of places where characters are converted to numbers (currently simply by subtracting 65 from the ASCII value)

Ok, but I think by now this post is waaaay long enough. I can definitely answer any questions you might have, but let's move that to the comments.

If you go the route of going into your Network Settings and getting Wi-Fi IP address such as xxx.xxx.x.xxx:9000 (:9000 or whichever port is open), make sure your mobile device is also on that same Wi-Fi/signal IP address. I spent a day trying to get this to work and it didn't work until i switched my phone off the cellular network to the same Wi-Fi connection/IP address. Opened right up once I made this update.

Another way hasn't been given yet:

try:
    1/0
except Exception, e:
    print e.message

Output:

integer division or modulo by zero

args[0] might actually not be a message.

str(e) might return the string with surrounding quotes and possibly with the leading u if unicode:

'integer division or modulo by zero'

repr(e) gives the full exception representation which is not probably what you want:

"ZeroDivisionError('integer division or modulo by zero',)"

edit

My bad !!! It seems that BaseException.message has been deprecated from 2.6, finally, it definitely seems that there is still not a standardized way to display exception messages. So I guess the best is to do deal with e.args and str(e) depending on your needs (and possibly e.message if the lib you are using is relying on that mechanism).

For instance, with pygraphviz, e.message is the only way to display correctly the exception, using str(e) will surround the message with u''.

But with MySQLdb, the proper way to retrieve the message is e.args[1]: e.message is empty, and str(e) will display '(ERR_CODE, "ERR_MSG")'

If I can throw my hat into the ring, I think there is a cleaner way than the existing answers to reuse the radio button functionality.

Let's say you have the following property in your ViewModel:

Public Class ViewModel
    <Display(Name:="Do you like Cats?")>
    Public Property LikesCats As Boolean
End Class

You can expose that property through a reusable editor template:

First, create the file Views/Shared/EditorTemplates/YesNoRadio.vbhtml

Then add the following code to YesNoRadio.vbhtml:

@ModelType Boolean?

<fieldset>
    <legend>
        @Html.LabelFor(Function(model) model)
    </legend>

    <label>
        @Html.RadioButtonFor(Function(model) model, True) Yes
    </label>
    <label>
        @Html.RadioButtonFor(Function(model) model, False) No
    </label>
</fieldset>

You can call the editor for the property by manually specifying the template name in your View:

@Html.EditorFor(Function(model) model.LikesCats, "YesNoRadio")

Pros:

• Get to write HTML in an HTML editor instead of appending strings in code behind.
• Preserves the DisplayName DataAnnotation
• Allows clicks on Label to toggle radio button
• Least possible code to maintain in form (1 line). If something is wrong with the way it is rending, take it up with the template.

Here is my version. It stores data based on categories.

import matplotlib.pyplot as plt
import numpy as np

data_a = [[1,2,5], [5,7,2,2,5], [7,2,5]]
data_b = [[6,4,2], [1,2,5,3,2], [2,3,5,1]]

ticks = ['A', 'B', 'C']

def set_box_color(bp, color):
    plt.setp(bp['boxes'], color=color)
    plt.setp(bp['whiskers'], color=color)
    plt.setp(bp['caps'], color=color)
    plt.setp(bp['medians'], color=color)

plt.figure()

bpl = plt.boxplot(data_a, positions=np.array(xrange(len(data_a)))*2.0-0.4, sym='', widths=0.6)
bpr = plt.boxplot(data_b, positions=np.array(xrange(len(data_b)))*2.0+0.4, sym='', widths=0.6)
set_box_color(bpl, '#D7191C') # colors are from http://colorbrewer2.org/
set_box_color(bpr, '#2C7BB6')

# draw temporary red and blue lines and use them to create a legend
plt.plot([], c='#D7191C', label='Apples')
plt.plot([], c='#2C7BB6', label='Oranges')
plt.legend()

plt.xticks(xrange(0, len(ticks) * 2, 2), ticks)
plt.xlim(-2, len(ticks)*2)
plt.ylim(0, 8)
plt.tight_layout()
plt.savefig('boxcompare.png')

I am short of reputation so I cannot post an image to here. You can run it and see the result. Basically it's very similar to what Molly did.

Note that, depending on the version of python you are using, you may need to replace xrange with range

Is it possible to get this above example:

jQuery.fn.highlight = function (str, className)
{
    var regex = new RegExp(str, "g");

    return this.each(function ()
    {
        this.innerHTML = this.innerHTML.replace(
            regex,
            "<span class=\"" + className + "\">" + str + "</span>"
        );
    });
};

not to replace text inside html-tags like , this otherwise breakes the page.

You can also use, django-adaptors

>>> from adaptor.model import CsvModel
>>> class MyCSvModel(CsvModel):
...     name = CharField()
...     age = IntegerField()
...     length = FloatField()
...
...     class Meta:
...         delimiter = ";"

You declare a MyCsvModel which will match to a CSV file like this:

Anthony;27;1.75

To import the file or any iterable object, just do:

>>> my_csv_list = MyCsvModel.import_data(data = open("my_csv_file_name.csv"))
>>> first_line = my_csv_list[0]
>>> first_line.age
    27

Without an explicit declaration, data and columns are matched in the same order:

Anthony --> Column 0 --> Field 0 --> name
27      --> Column 1 --> Field 1 --> age
1.75    --> Column 2 --> Field 2 --> length

In my case, it was just because I didn't set the height and width.

But there is another issue.

The background image could be removed using

element.style.backgroundImage=""

but couldn't be set using

element.style.backgroundImage="some base64 data"

Using ionic 4 with angular 7

Your code is almost right! You are right, you are just missing one step. When you read in the file, you are reading it as a string; but you want to turn the string back into a dictionary.

The error message you saw was because self.whip was a string, not a dictionary.

I first wrote that you could just feed the string into dict() but that doesn't work! You need to do something else.

Example

Here is the simplest way: feed the string into eval(). Like so:

def reading(self):
    s = open('deed.txt', 'r').read()
    self.whip = eval(s)

You can do it in one line, but I think it looks messy this way:

def reading(self):
    self.whip = eval(open('deed.txt', 'r').read())

But eval() is sometimes not recommended. The problem is that eval() will evaluate any string, and if someone tricked you into running a really tricky string, something bad might happen. In this case, you are just running eval() on your own file, so it should be okay.

But because eval() is useful, someone made an alternative to it that is safer. This is called literal_eval and you get it from a Python module called ast.

import ast

def reading(self):
    s = open('deed.txt', 'r').read()
    self.whip = ast.literal_eval(s)

ast.literal_eval() will only evaluate strings that turn into the basic Python types, so there is no way that a tricky string can do something bad on your computer.

EDIT

Actually, best practice in Python is to use a with statement to make sure the file gets properly closed. Rewriting the above to use a with statement:

import ast

def reading(self):
    with open('deed.txt', 'r') as f:
        s = f.read()
        self.whip = ast.literal_eval(s)

In the most popular Python, known as "CPython", you usually don't need the with statement as the built-in "garbage collection" features will figure out that you are done with the file and will close it for you. But other Python implementations, like "Jython" (Python for the Java VM) or "PyPy" (a really cool experimental system with just-in-time code optimization) might not figure out to close the file for you. It's good to get in the habit of using with, and I think it makes the code pretty easy to understand.

or you can also do ( for pem file )

 scp -r -i file.pem [email protected]:/home/backup /home/user/Desktop/

Here is a simpler option that works when I encounter this.

After you create the connection, select the connection and open the Properties. In the Expressions category find Password. Re-enter the password and hit Enter. It will now be saved to the connection.

Big-O is an upper bound.

Big-Theta is a tight bound, i.e. upper and lower bound.

When people only worry about what's the worst that can happen, big-O is sufficient; i.e. it says that "it can't get much worse than this". The tighter the bound the better, of course, but a tight bound isn't always easy to compute.

See also

• Wikipedia/Big O Notation

Related questions

• What is the difference between T(n) and O(n)?

The following quote from Wikipedia also sheds some light:

Informally, especially in computer science, the Big O notation often is permitted to be somewhat abused to describe an asymptotic tight bound where using Big Theta notation might be more factually appropriate in a given context.

For example, when considering a function T(n) = 73n³+ 22n²+ 58, all of the following are generally acceptable, but tightness of bound (i.e., bullets 2 and 3 below) are usually strongly preferred over laxness of bound (i.e., bullet 1 below).

1. T(n) = O(n¹⁰⁰), which is identical to T(n) ? O(n¹⁰⁰)
2. T(n) = O(n³), which is identical to T(n) ? O(n³)
3. T(n) = T(n³), which is identical to T(n) ? T(n³)

The equivalent English statements are respectively:

1. T(n) grows asymptotically no faster than n¹⁰⁰
2. T(n) grows asymptotically no faster than n³
3. T(n) grows asymptotically as fast as n³.

So while all three statements are true, progressively more information is contained in each. In some fields, however, the Big O notation (bullets number 2 in the lists above) would be used more commonly than the Big Theta notation (bullets number 3 in the lists above) because functions that grow more slowly are more desirable.

@Min and @Max are used for validating numeric fields which could be String(representing number), int, short, byte etc and their respective primitive wrappers.

@Size is used to check the length constraints on the fields.

As per documentation @Size supports String, Collection, Map and arrays while @Min and @Max supports primitives and their wrappers. See the documentation.

Mayb it's easier (and has more performance) if you delegate the event handling to another element, for example your table

$('idOfYourTable').on("click", "input:checkbox", function(){

});

in this way you will have only one event handler, and this will work also for newly added elements. This requires jQuery >= 1.7

Otherwise use delegate()

$('idOfYourTable').delegate("input:checkbox", "click", function(){

});

Actually, it feels like swift is trying to promote strings to be treated less like objects and more like values. However this doesn't mean under the hood swift doesn't treat strings as objects, as am sure you all noticed that you can still invoke methods on strings and use their properties.

For example:-

//example of calling method (String to Int conversion)
let intValue = ("12".toInt())
println("This is a intValue now \(intValue)")


//example of using properties (fetching uppercase value of string)
let caUpperValue = "ca".uppercaseString
println("This is the uppercase of ca \(caUpperValue)")

In objectC you could pass the reference to a string object through a variable, on top of calling methods on it, which pretty much establishes the fact that strings are pure objects.

Here is the catch when you try to look at String as objects, in swift you cannot pass a string object by reference through a variable. Swift will always pass a brand new copy of the string. Hence, strings are more commonly known as value types in swift. In fact, two string literals will not be identical (===). They are treated as two different copies.

let curious = ("ca" === "ca")
println("This will be false.. and the answer is..\(curious)")

As you can see we are starting to break aways from the conventional way of thinking of strings as objects and treating them more like values. Hence .isEqualToString which was treated as an identity operator for string objects is no more a valid as you can never get two identical string objects in Swift. You can only compare its value, or in other words check for equality(==).

 let NotSoCuriousAnyMore = ("ca" == "ca")
 println("This will be true.. and the answer is..\(NotSoCuriousAnyMore)")

This gets more interesting when you look at the mutability of string objects in swift. But thats for another question, another day. Something you should probably look into, cause its really interesting. :) Hope that clears up some confusion. Cheers!

Sorry for answering it bit late; There is a pre-defined function in the Angular Routing Documentation which helps us in routing with a hashtag to page anchor i.e, anchorScrolling: 'enabled'

Step-1:- First Import the RouterModule in the app.module.ts file:-

imports:[ 
    BrowserModule, 
    FormsModule,
    RouterModule.forRoot(routes,{
      anchorScrolling: 'enabled'
    })
  ],

Step-2:- Go to the HTML Page, Create the navigation and add two important attributes like [routerLink] and fragment for matching the respective Div ID's:-

<ul>
    <li> <a [routerLink] = "['/']"  fragment="home"> Home </a></li>
    <li> <a [routerLink] = "['/']"  fragment="about"> About Us </a></li>
  <li> <a [routerLink] = "['/']"  fragment="contact"> Contact Us </a></li>
</ul>

Step-3:- Create a section/div by matching the ID name with the fragment:-

<section id="home" class="home-section">
      <h2>  HOME SECTION </h2>
</section>

<section id="about" class="about-section">
        <h2>  ABOUT US SECTION </h2>
</section>

<section id="contact" class="contact-section">
        <h2>  CONTACT US SECTION </h2>
</section>

For your reference, I have added the example below by creating a small demo which helps to solve your problem.

Demo : https://routing-hashtag-page-anchors.stackblitz.io/

If you added secureTextEntry={true} but did not work then check the multiline={true} prop, because if it is true, secureTextEntry does not work.

For Rails 3 you can use this command to create a new project using mysql:

$ rails new projectname -d mysql

Below are the steps you can try it out to resolve the issue: -

1. Provide reference of AppCompat Library into your project.
2. If option 1 doesn't solve the issue then you can try to change the style.xml file to below code.

 parent="android:Theme.Holo.Light"  

instead.

 parent="android:Theme.AppCompat.Light"  

But option 2 will require minimum sdk version 14.

Hope this will help !

Not possible without assigning height value to div.

Add this

body, html{height:100%}
div{height:100%}
table{background:green; width:450px}    ?

Use Max-Age=-1 rather than "Expires". It is shorter, less picky about the syntax, and Max-Age takes precedence over Expires anyway.

SELECT *
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE TABLE_SCHEMA = 'test' AND TABLE_NAME ='products'; 

where Table_schema is database name

You can use the method SelectTab.

There are 3 versions:

public void SelectTab(int index);
public void SelectTab(string tabPageName);
public void SelectTab(TabPage tabPage);

You can't pass a parameter in a @selector().

It looks like you're trying to implement a callback. The best way to do that would be something like this:

[object setCallbackObject:self withSelector:@selector(myMethod:)];

Then in your object's setCallbackObject:withSelector: method: you can call your callback method.

-(void)setCallbackObject:(id)anObject withSelector:(SEL)selector {
    [anObject performSelector:selector];
}

check program with this input:abc/if you got something like ab ac bc abc program works well and you need a stronger RAM otherwise the program is wrong.

No, you can't do this in Java. Aside from anything else, d would then presumably be an instance of A (given the normal idea of "extends"), but users who only knew about A wouldn't know about it - which defeats the point of an enum being a well-known set of values.

If you could tell us more about how you want to use this, we could potentially suggest alternative solutions.

The problem in the jsfiddle is that your dummy text is all one word. If you use your lorem ipsum given in the question, then the text wraps fine.

If you want large words to be broken mid-word and wrap around, add this to your .title css:

word-wrap: break-word;

for (Int32 i = 1; i < dt_pattern.Rows.Count - 1; i++){ double yATmax = ToDouble(dt_pattern.Rows[i]["Ampl"].ToString()) + AT; }

if you want to get around the + 1 issue

In addition of all answers. You can also specify the minsdk to apply with this annotation

@TargetApi(_apiLevel_)

I used this in order to accept this request even my minsdk is 18. What it does is that the method only runs when device targets "_apilevel_" and upper. Here's my method:

    @TargetApi(23)
void solicitarPermisos(){

    if (ContextCompat.checkSelfPermission(this,permiso)
            != PackageManager.PERMISSION_GRANTED) {

        // Should we show an explanation?
        if (shouldShowRequestPermissionRationale(
                Manifest.permission.READ_EXTERNAL_STORAGE)) {
            // Explain to the user why we need to read the contacts
        }

        requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
                1);

        // MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE is an
        // app-defined int constant that should be quite unique

        return;
    }

}

I'm not sure about the "@" used in the selector. At least with the latest jQuery, I had to remove the @ to get this to function with two different checkbox arrays, otherwise all checked items were selected for each array:

var items = [];
$("input[name='items[]']:checked").each(function(){items.push($(this).val());});

var about = [];
$("input[name='about[]']:checked").each(function(){about.push($(this).val());});

Now both, items and about work.

If you don't want to change your default settings, and you only want to change the width of the current notebook you're working on, you can enter the following into a cell:

from IPython.core.display import display, HTML
display(HTML("<style>.container { width:100% !important; }</style>"))

You can use double quotes if ANSI SQL mode is enabled

CREATE TABLE IF NOT EXISTS misc_info
  (
     id    INTEGER PRIMARY KEY AUTO_INCREMENT NOT NULL,
     "key" TEXT UNIQUE NOT NULL,
     value TEXT NOT NULL
  )
ENGINE=INNODB; 

or the proprietary back tick escaping otherwise. (Where to find the ` character on various keyboard layouts is covered in this answer)

CREATE TABLE IF NOT EXISTS misc_info
  (
     id    INTEGER PRIMARY KEY AUTO_INCREMENT NOT NULL,
     `key` TEXT UNIQUE NOT NULL,
     value TEXT NOT NULL
  )
ENGINE=INNODB;

Just to complete this with an equivalent method chain syntax:

entity.Join(entity2, x => new {x.Field1, x.Field2},
                     y => new {y.Field1, y.Field2}, (x, y) => x);

While the last argument (x, y) => x is what you select (in the above case we select x).

In Visual Studio 2008 + , go to the

Tools menu -->  select Options 

In Options Window --> expand Source Control --> Select Subversion User Tools --> Select Beyond Compare

and click OK button..

Contrary to @Andre Luus, setting Height="Auto" will not make the TextBox stretch. The solution I found was to set VerticalAlignment="Stretch"

Though it is answered above and it is right to use

<meta name="viewport" content="width=device-width, initial-scale=1">

but if you are using React and webpack then don't forget to close the element tag

<meta name="viewport" content="width=device-width, initial-scale=1" />

It will be something like this:

SELECT b.Title, b.Edition, b.Year, b.Pages, b.Rating, c.Category, p.Publisher, w.LastName
FROM
    Books b
    JOIN Categories_Book cb ON cb._ISBN = b._Books_ISBN
    JOIN Category c ON c._CategoryID = cb._Categories_Category_ID
    JOIN Publishers p ON p._PublisherID = b.PublisherID
    JOIN Writers_Books wb ON wb._Books_ISBN = b._ISBN
    JOIN Writer w ON w._WritersID = wb._Writers_WriterID

You use the join statement to indicate which fields from table A map to table B. I'm using aliases here thats why you see Books b the Books table will be referred to as b in the rest of the query. This makes for less typing.

FYI your naming convention is very strange, I would expect it to be more like this:

Book: ID, ISBN , BookTitle, Edition, Year, PublisherID, Pages, Rating
Category: ID, [Name]
BookCategory: ID, CategoryID, BookID
Publisher: ID, [Name]
Writer: ID, LastName
BookWriter: ID, WriterID, BookID

You can use zip with * to get transpose of a matrix:

>>> A = [[ 1, 2, 3],[ 4, 5, 6]]
>>> zip(*A)
[(1, 4), (2, 5), (3, 6)]
>>> lis  = [[1,2,3], 
... [4,5,6],
... [7,8,9]]
>>> zip(*lis)
[(1, 4, 7), (2, 5, 8), (3, 6, 9)]

If you want the returned list to be a list of lists:

>>> [list(x) for x in zip(*lis)]
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]
#or
>>> map(list, zip(*lis))
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]

This answer is for the first question, why it takes so much time and it offers an alternative solution for exporting the DataGridView to Excel.

MS Office Interop is slow and even Microsoft does not recommend Interop usage on server side and cannot be use to export large Excel files. For more details see why not to use OLE Automation from Microsoft point of view.

Interop saves Excel files in XLS file format (old Excel 97-2003 file format) and the support for Office 2003 has ended. Microsoft Excel released XLSX file format with Office 2007 and recommends the usage of OpenXML SDK instead of Interop. But XLSX files are not really so fast and doesn’t handle very well large Excel files because they are based on XML file format. This is why Microsoft also released XLSB file format with Office 2007, file format that is recommended for large Excel files. It is a binary format. So the best and fastest solution is to save XLSB files.

You can use this C# Excel library to save XLSB files, but it also supports XLS and XLSX file formats.

See the following code sample as alternative of exporting DataGridView to Excel:

// Create a DataSet and add the DataTable of DataGridView 
DataSet dataSet = new DataSet();
dataSet.Tables.Add((DataTable)dataGridView);
//or ((DataTable)dataGridView.DataSource).Copy() to create a copy

// Export Excel file 
ExcelDocument workbook = new ExcelDocument();
workbook.easy_WriteXLSBFile_FromDataSet(filePath, dataSet, 
     new EasyXLS.ExcelAutoFormat(EasyXLS.Constants.Styles.AUTOFORMAT_EASYXLS1), 
     "Sheet1");

If you also need to export the formatting of the DataGridView check this code sample on how to export datagridview to Excel in C#.

Java 8 Lambda shortens the sort.

Collections.sort(stdList, (o1, o2) -> o1.getName().compareTo(o2.getName()));

base is the number that you want to power up, n is the power, we return 1 if n is 0, and we return the base if the n is 1, if the conditions are not met, we use the formula base*(powerN(base,n-1)) eg: 2 raised to to using this formula is : 2(base)*2(powerN(base,n-1)).

public int power(int base, int n){
   return n == 0 ? 1 : (n == 1 ? base : base*(power(base,n-1)));

The envdir utility provides an easy way to do this. envdir uses files to represent environment variables, with file names mapping to env var names, and file contents mapping to env var values. If the file contents contain newlines, so will the env var.

See https://pypi.python.org/pypi/envdir

You can also run into this if you're working on a WPF project that was started in VS 2010 (Beta 1), then moved into VS 2008.

Under the project properties, the .NET framework version gets unset (since .NET 4.0 isn't valid in VS 2008), and for some reason that causes this error.

If you set the .NET framework (e.g. to .NET 3.5), the error goes away.

I had to switch from Eclipse Oxygen that I got from IBM and used IBM JDK 8 to Eclipse Photon and Oracle JDK 8. I'm working on Java customizations for maximo.

The simplest way of doing this is to

1. open up SQL Management Studio
2. navigate to your database
3. Right-click and select Tasks->Generate Scripts (pic 1)
4. On the "choose Objects" screen, select the "select specific objects" option and check "tables" (pic 2)
5. on the next screen, select "advanced" and then change the "Script DROP and CREATE" option to "Script DROP and CREATE" (pic 3)
6. Choose to save script to a new editor window or a file and run as necessary.

this will give you a script that drops and recreates all your tables without the need to worry about debugging or whether you've included everything. While this performs more than just a truncate, the results are the same. Just keep in mind that your auto-incrementing primary keys will start at 0, as opposed to truncated tables which will remember the last value assigned. You can also execute this from code if you don't have access to Management studio on your PreProd or Production environments.

I had the same problem. Solved it by using a javascript library called FileSaver

Just call

saveAs(file, 'filename');

Full http post request:

$http.post('apiUrl', myObject, { responseType: 'arraybuffer' })
  .success(function(data) {
            var file = new Blob([data], { type: 'application/pdf' });
            saveAs(file, 'filename.pdf');
        });

Try the following:

print "First is: %f" % (first)
print "Second is: %f" % (second)

I am unsure what answer is. But apart from that, this will be:

print "DONE: %f DIVIDED BY %f EQUALS %f, SWEET MATH BRO!" % (first, second, ans)

There's a lot of text on Format String Specifiers. You can google it and get a list of specifiers. One thing I forgot to note:

If you try this:

print "First is: %s" % (first)

It converts the float value in first to a string. So that would work as well.

Checkout TickTick.

It's a true Bash JSON parser.

#!/bin/bash
. /path/to/ticktick.sh

# File
DATA=`cat data.json`
# cURL
#DATA=`curl http://foobar3000.com/echo/request.json`

tickParse "$DATA"

echo ``pathname``
echo ``headers["user-agent"]``

In addition to Doug Kavendek answer. One could use the following approach to get closer to tz_database.

1. Download [Free Zip Code Latitude and Longitude Database]
2. Download [A shapefile of the TZ timezones of the world]
3. Use any free library for shapefile querying (e.g. .NET Easy GIS .NET, LGPL).

    var shapeFile = new ShapeFile(shapeFilePath);
    var shapeIndex = shapeFile.GetShapeIndexContainingPoint(new PointD(long, lat), 0D);
    var attrValues = shapeFile.GetAttributeFieldValues(shapeIndex);
    var timeZoneId = attrValues[0];

P.S. Can't insert all the links :( So please use search.

I would like to add a word of warning when you are dealing with C++11-style allocator-aware containers. Swapping and assignment have subtly different semantics.

For concreteness, let us consider a container std::vector<T, A>, where A is some stateful allocator type, and we'll compare the following functions:

void fs(std::vector<T, A> & a, std::vector<T, A> & b)
{ 
    a.swap(b);
    b.clear(); // not important what you do with b
}

void fm(std::vector<T, A> & a, std::vector<T, A> & b)
{
    a = std::move(b);
}

The purpose of both functions fs and fm is to give a the state that b had initially. However, there is a hidden question: What happens if a.get_allocator() != b.get_allocator()? The answer is: It depends. Let's write AT = std::allocator_traits<A>.

• If AT::propagate_on_container_move_assignment is std::true_type, then fm reassigns the allocator of a with the value of b.get_allocator(), otherwise it does not, and a continues to use its original allocator. In that case, the data elements need to be swapped individually, since the storage of a and b is not compatible.

• If AT::propagate_on_container_swap is std::true_type, then fs swaps both data and allocators in the expected fashion.

• If AT::propagate_on_container_swap is std::false_type, then we need a dynamic check.

  • If a.get_allocator() == b.get_allocator(), then the two containers use compatible storage, and swapping proceeds in the usual fashion.
  • However, if a.get_allocator() != b.get_allocator(), the program has undefined behaviour (cf. [container.requirements.general/8].

The upshot is that swapping has become a non-trivial operation in C++11 as soon as your container starts supporting stateful allocators. That's a somewhat "advanced use case", but it's not entirely unlikely, since move optimizations usually only become interesting once your class manages a resource, and memory is one of the most popular resources.

The XTend language — which is a super-set of Java, and compiles to Java source code¹ — supports this.

1. index.html file should come under below location - src/resources/public/index.html OR src/resources/static/index.html if both location defined then which first occur index.html will call from that directory.

2. The source code looks like -

   package com.bluestone.pms.app.boot; 
   import org.springframework.boot.Banner;
   import org.springframework.boot.Banner;
   import org.springframework.boot.SpringApplication;
   import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
   import org.springframework.boot.autoconfigure.SpringBootApplication;
   import org.springframework.boot.builder.SpringApplicationBuilder;
   import org.springframework.boot.web.support.SpringBootServletInitializer;
   import org.springframework.context.annotation.ComponentScan;
   
   
   
   @SpringBootApplication 
   @EnableAutoConfiguration
   @ComponentScan(basePackages = {"com.your.pkg"}) 
   public class BootApplication extends SpringBootServletInitializer {
   
   
   
   /**
    * @param args Arguments
   */
   public static void main(String[] args) {
   SpringApplication application = new SpringApplication(BootApplication.class);
   /* Setting Boot banner off default value is true */
   application.setBannerMode(Banner.Mode.OFF);
   application.run(args);
   }
   
   /**
     * @param builder a builder for the application context
     * @return the application builder
     * @see SpringApplicationBuilder
    */
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder 
     builder) {
       return super.configure(builder);
      }
   }

Now you can use mysql.connector to retrive a dictionary as shown here: https://dev.mysql.com/doc/connector-python/en/connector-python-api-mysqlcursordict.html

Here is the example on the mysql site:

cnx = mysql.connector.connect(database='world')
cursor = cnx.cursor(dictionary=True)
cursor.execute("SELECT * FROM country WHERE Continent = 'Europe'")

print("Countries in Europe:")
for row in cursor:
    print("* {Name}".format(Name=row['Name']))

str_replace will do the trick thusly

$new_str = str_replace(' ', '', $old_str);

If your app is behind a trusted proxy (e.g. an AWS ELB or a correctly configured nginx), this code should work:

app.enable('trust proxy');
app.use(function(req, res, next) {
    if (req.secure){
        return next();
    }
    res.redirect("https://" + req.headers.host + req.url);
});

Notes:

• This assumes that you're hosting your site on 80 and 443, if not, you'll need to change the port when you redirect
• This also assumes that you're terminating the SSL on the proxy. If you're doing SSL end to end use the answer from @basarat above. End to end SSL is the better solution.
• app.enable('trust proxy') allows express to check the X-Forwarded-Proto header

Also you can use dirname(__DIR__, $level) for access any folding level without traversing

Use .append instead of .html

var response = "[{
      "rank":"9",
      "content":"Alon",
      "UID":"5"
     },
     {
       "rank":"6",
       "content":"Tala",
       "UID":"6"
    }]";

// convert string to JSON
response = $.parseJSON(response);

$(function() {
    $.each(response, function(i, item) {
        var $tr = $('<tr>').append(
            $('<td>').text(item.rank),
            $('<td>').text(item.content),
            $('<td>').text(item.UID)
        ); //.appendTo('#records_table');
        console.log($tr.wrap('<p>').html());
    });
});

For that single rule you have, there isn't any shorter way to do it. The child combinator is the same in CSS and in Sass/SCSS and there's no alternative to it.

However, if you had multiple rules like this:

#foo > ul > li > ul > li > a:nth-child(3n+1) {
    color: red;
}

#foo > ul > li > ul > li > a:nth-child(3n+2) {
    color: green;
}

#foo > ul > li > ul > li > a:nth-child(3n+3) {
    color: blue;
}

You could condense them to one of the following:

/* Sass */
#foo > ul > li > ul > li
    > a:nth-child(3n+1)
        color: red
    > a:nth-child(3n+2)
        color: green
    > a:nth-child(3n+3)
        color: blue

/* SCSS */
#foo > ul > li > ul > li {
    > a:nth-child(3n+1) { color: red; }
    > a:nth-child(3n+2) { color: green; }
    > a:nth-child(3n+3) { color: blue; }
}

You can think of reshaping that the new shape is filled row by row (last dimension varies fastest) from the flattened original list/array.

An easy solution is to shape the list into a (100, 28) array and then transpose it:

x = np.reshape(list_data, (100, 28)).T

Update regarding the updated example:

np.reshape([0, 0, 1, 1, 2, 2, 3, 3], (4, 2)).T
# array([[0, 1, 2, 3],
#        [0, 1, 2, 3]])

np.reshape([0, 0, 1, 1, 2, 2, 3, 3], (2, 4))
# array([[0, 0, 1, 1],
#        [2, 2, 3, 3]])

According to the java.io.File Java Docs

The default temporary-file directory is specified by the system property java.io.tmpdir. On UNIX systems the default value of this property is typically "/tmp" or "/var/tmp"; on Microsoft Windows systems it is typically "c:\temp". A different value may be given to this system property when the Java virtual machine is invoked, but programmatic changes to this property are not guaranteed to have any effect upon the the temporary directory used by this method.

To specify the java.io.tmpdir System property, you can invoke the JVM as follows:

java -Djava.io.tmpdir=/path/to/tmpdir

By default this value should come from the TMP environment variable on Windows systems

Also in the many IDEs now, ex: VSC, you can install an extension for AWS and simply click upload from there, no effort of typing all those commands + region.

Here's an example:

I have started using inputmode="decimal" which works flawlessly with smartphones:

<input type="text" inputmode="decimal" value="1.5">

Note that we have to use type="text" instead of number. However, on desktop it still allows letters as values.

For desktop you could use:

<input type="number" inputmode="decimal">

which allows 0-9 and . as input and only numbers.

Note that some countries use , as decimal dividor which is activated as default on the NumPad. Thus entering a float number by Numpad would not work as the input field expects a . (in Chrome). That's why you should use type="text" if you have international users on your website.

You can try this on desktop (also with Numpad) and your phone:

<p>Input with type text:</p>
<input type="text" inputmode="decimal" value="1.5">
<br>
<p>Input with type number:</p>
<input type="number" inputmode="decimal" value="1.5">

You can pass the configuration name to the post-build script and check it in there to see if it should run.

Pass the configuration name with $(ConfigurationName).

Checking it is based on how you are implementing the post-build step -- it will be a command-line argument.

def player(game_over):
    do something here
    game_over = check_winner() #Here we tell check_winner to run and tell us what game_over should be, either true or false
    if not game_over: 
        computer(game_over)  #We are only going to do this if check_winner comes back as False

def check_winner(): 
    check something
    #here needs to be an if / then statement deciding if the game is over, return True if over, false if not
    if score == 100:
        return True
    else:
        return False

def computer(game_over):
    do something here
    game_over = check_winner() #Here we tell check_winner to run and tell us what game_over should be, either true or false
    if not game_over:
        player(game_over) #We are only going to do this if check_winner comes back as False

game_over = False   #We need a variable to hold wether the game is over or not, we'll start it out being false.
player(game_over)   #Start your loops, sending in the status of game_over

Above is a pretty simple example... I made up a statement for check_winner using score = 100 to denote the game being over.

You will want to use similar method of passing score into check_winner, using game_over = check_winner(score). Then you can create a score at the beginning of your program and pass it through to computer and player just like game_over is being handled.

You can use the built-in function:

extract($_POST);

it will create a variable for each entry in $_POST.

i use colname(train) = paste("A", colname(train)) and it turns out to the same problem as yours.

I finally figure out that randomForest is more stingy than rpart, it can't recognize the colname with space, comma or other specific punctuation.

paste function will prepend "A" and " " as seperator with each colname. so we need to avert the space and use this sentence instead:

colname(train) = paste("A", colname(train), sep = "")

this will prepend string without space.

Try this for Windows:

    npm uninstall -g cordova

Try this for MAC:

    sudo npm uninstall -g cordova

You can also add Cordova like this:

1. If You Want To install the previous version of Cordova through the Node Package Manager (npm):

   npm install -g [email protected]
   

2. If You Want To install the latest version of Cordova:

   npm install -g cordova 
   

Enjoy!

With Git 2.23 (August 2019), that would be, using git switch -f:

git switch -f master

That avoids the confusion with git checkout (which deals with files or branches).

And that will proceeds, even if the index or the working tree differs from HEAD.
Both the index and working tree are restored to match the switching target.
If --recurse-submodules is specified, submodule content is also restored to match the switching target.
This is used to throw away local changes.

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt


def butter_lowpass(cutoff, fs, order=5):
    nyq = 0.5 * fs
    normal_cutoff = cutoff / nyq
    b, a = butter(order, normal_cutoff, btype='low', analog=False)
    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()

plt.subplots_adjust(hspace=0.35)
plt.show()

The convention is to ask a question in the name.

Here are a few examples that can be found in the JDK:

isEmpty()

hasChildren()

That way, the names are read like they would have a question mark on the end.

Is the Collection empty?
Does this Node have children?

And, then, true means yes, and false means no.

Or, you could read it like an assertion:

The Collection is empty.
The node has children

Note:
Sometimes you may want to name a method something like createFreshSnapshot?. Without the question mark, the name implies that the method should be creating a snapshot, instead of checking to see if one is required.

In this case you should rethink what you are actually asking. Something like isSnapshotExpired is a much better name, and conveys what the method will tell you when it is called. Following a pattern like this can also help keep more of your functions pure and without side effects.

If you do a Google Search for isEmpty() in the Java API, you get lots of results.

you can save them into a $_SESSION variable and then when the user calls that page again populate all the inputs with their respective session variables.

You can use https://github.com/mxcl/OMGHTTPURLRQ

id config = [NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:someID];
id session = [NSURLSession sessionWithConfiguration:config delegate:someObject delegateQueue:[NSOperationQueue new]];

OMGMultipartFormData *multipartFormData = [OMGMultipartFormData new];
[multipartFormData addFile:data1 parameterName:@"file1" filename:@"myimage1.png" contentType:@"image/png"];

NSURLRequest *rq = [OMGHTTPURLRQ POST:url:multipartFormData];

id path = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:@"upload.NSData"];
[rq.HTTPBody writeToFile:path atomically:YES];

[[session uploadTaskWithRequest:rq fromFile:[NSURL fileURLWithPath:path]] resume];

Timeout /t 1 >nul

Is like pause in 1 secound, you can take the limed to almost 100.000 (99.999) secounds. If you are connected to the internet the best solution would be:

ping 1.1.1.1. -n 1 -w 1000 >nul

When you ping you count in milliseconds, so one second would be 1000 milliseconds. But the ping command is a little iffy, it does not work the same way on offline machines. The problem is that the machine gets confused because it is offline, and it would like to ping a website/server/host/ip, but it can't. So i would recommend timeout. Good luck!

IntelliJ has intellisense and refactoring support from code into jspx documents.

May be SSMS: How to import (Copy/Paste) data from excel can help (If you don't want to use BULK INSERT or don't have permissions for it).

The complete syntax depends on the database engine you're working with:

For SQL Server:

CASE case-expression
    WHEN when-expression-1 THEN value-1
  [ WHEN when-expression-n THEN value-n ... ]
  [ ELSE else-value ]
END

or:

CASE
    WHEN boolean-when-expression-1 THEN value-1
  [ WHEN boolean-when-expression-n THEN value-n ... ]
  [ ELSE else-value ]
END

expressions, etc:

case-expression    - something that produces a value
when-expression-x  - something that is compared against the case-expression
value-1            - the result of the CASE statement if:
                         the when-expression == case-expression
                      OR the boolean-when-expression == TRUE
boolean-when-exp.. - something that produces a TRUE/FALSE answer

Link: CASE (Transact-SQL)

Also note that the ordering of the WHEN statements is important. You can easily write multiple WHEN clauses that overlap, and the first one that matches is used.

Note: If no ELSE clause is specified, and no matching WHEN-condition is found, the value of the CASE expression will be NULL.

For me the solution was besides using "Ntlm" as credential type, similar as Jeroen K's solution. If I had the permission level I would plus on his post, but let me post my whole code here, which will support both Windows and other credential types like basic auth:

    XxxSoapClient xxxClient = new XxxSoapClient();
    ApplyCredentials(userName, password, xxxClient.ClientCredentials);

    private static void ApplyCredentials(string userName, string password, ClientCredentials clientCredentials)
    {
        clientCredentials.UserName.UserName = userName;
        clientCredentials.UserName.Password = password;
        clientCredentials.Windows.ClientCredential.UserName = userName;
        clientCredentials.Windows.ClientCredential.Password = password;
        clientCredentials.Windows.AllowNtlm = true;
        clientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;
    }  

I found a way to get the arguments with an equal sign (=)! The answer is especially an addition to @lesmana 's answer (as it is the most complete and explained one here), but it would be too big to write it as a comment. Again, I repeat his message: TL;DR don't try to do this!

I needed a way to treat my argument --xyz-enabled=false (since the default is true), which we all know by now that this is not a make target and thus not part of $(MAKECMDGOALS).

While looking into all variables of make by echoing the $(.VARIABLES) i got these interesting outputs:

[...] -*-command-variables-*- --xyz-enabled [...]

This allows us to go two ways: either getting all starting with a -- (if that applies to your case), or look into the GNU make specific (probably not intended for us to use) variable -*-command-variables-*-. ** See footer for additional options ** In my case this variable held:

--xyz-enabled=false

With this variable we can combine it with the already existing solution with $(MAKECMDGOALS) and thus by defining:

# the other technique to invalidate other targets is still required, see linked post
run:
    @echo ./prog $(-*-command-variables-*-) $(filter-out $@,$(MAKECMDGOALS))`

and using it with (explicitly mixing up order of arguments):

make run -- config --xyz-enabled=false over=9000 --foo=bar show  isit=alwaysreversed? --help

returned:

./prog isit=alwaysreversed? --foo=bar over=9000 --xyz-enabled=false config show --help

As you can see, we loose the total order of the args. The part with the "assignment"-args seem to have been reversed, the order of the "target"-args are kept. I placed the "assignment"-args in the beginning, hopefully your program doesn't care where the argument is placed.

Update: following make variables look promising as well:

MAKEFLAGS =  -- isit=alwaysreverse? --foo=bar over=9000 --xyz-enabled=false
MAKEOVERRIDES = isit=alwaysreverse? --foo=bar over=9000 --xyz-enabled=false

you can do like this also

        long[,] arr = new long[4, 4] { { 0, 0, 0, 0 }, { 1, 1, 1, 1 }, { 0, 0, 0, 0 }, { 1, 1, 1, 1 }};

        for (int i = 0; i < arr.GetLength(0); i++)
        {
            for (int j = 0; j < arr.GetLength(1); j++)
            {
                Console.Write(arr[i,j]+" ");
            }
            Console.WriteLine();
        }

Following code works..

datePickerButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showDialog(0);
        }
    });

@Override
@Deprecated
protected Dialog onCreateDialog(int id) {
    return new DatePickerDialog(this, datePickerListener, year, month, day);
}

private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
    public void onDateSet(DatePicker view, int selectedYear,
                          int selectedMonth, int selectedDay) {
        day = selectedDay;
        month = selectedMonth;
        year = selectedYear;
        datePickerButton.setText(selectedDay + " / " + (selectedMonth + 1) + " / "
                + selectedYear);
    }
};

Both of them uses TCP as a transport protocol, but HTTP uses a persistent connection, which makes the performance of the TCP better.

You need to download log4j and add in your classpath.

I would recommend a combination of PatIndex and Left. Carefully constructed, you can write a query that always works, no matter what your data looks like.

Ex:

Declare @Temp Table(Data VarChar(20))

Insert Into @Temp Values('BTA200')
Insert Into @Temp Values('BTA50')
Insert Into @Temp Values('BTA030')
Insert Into @Temp Values('BTA')
Insert Into @Temp Values('123')
Insert Into @Temp Values('X999')

Select Data, Left(Data, PatIndex('%[0-9]%', Data + '1') - 1)
From   @Temp

PatIndex will look for the first character that falls in the range of 0-9, and return it's character position, which you can use with the LEFT function to extract the correct data. Note that PatIndex is actually using Data + '1'. This protects us from data where there are no numbers found. If there are no numbers, PatIndex would return 0. In this case, the LEFT function would error because we are using Left(Data, PatIndex - 1). When PatIndex returns 0, we would end up with Left(Data, -1) which returns an error.

There are still ways this can fail. For a full explanation, I encourage you to read:

Extracting numbers with SQL Server

That article shows how to get numbers out of a string. In your case, you want to get alpha characters instead. However, the process is similar enough that you can probably learn something useful out of it.

The simplest way is using HTML META tag like this:

<meta http-equiv="refresh" content="3;url=http://example.com/" />

1. you have to have a reference to the form object in order to access its elements
2. the elements have to be declared public in order for another class to access them
3. don't do this - your class has to know too much about how your form is implemented; do not expose form controls outside of the form class
4. instead, make public properties on your form to get/set the values you are interested in
5. post more details of what you want and why, it sounds like you may be heading off in a direction that is not consistent with good encapsulation practices

Trying to answer a personal problem and similar to yours I found on Pandas Doc what I think would answer this question:

DataFrame.shift(periods=1, freq=None, axis=0) Shift index by desired number of periods with an optional time freq

Notes

If freq is specified then the index values are shifted but the data is not realigned. That is, use freq if you would like to extend the index when shifting and preserve the original data.

Hope to help future questions in this matter.
