Quotes!

if [ "$1" != -v ]; then

Otherwise, when $1 is completely empty, your test becomes:

[ != -v ]

instead of

[ "" != -v ]

...and != is not a unary operator (that is, one capable of taking only a single argument).

From the doc:

file location:

res/drawable/filename.xml

The filename is used as the resource ID.

basically, you'll need to put a file named list_divider.xml in res/drawable/ so you can access it as R.drawable.list_divider; if you can access it that way, then you can use android:divider="@drawable/list_divider" in the XML for ListView.

If you want to use Linq then you can use the following snippet:

var listNumber = dicNumber.Keys.ToList();

Here is an example for toggling bold, underline, and italics.

   protected override bool ProcessCmdKey( ref Message msg, Keys keyData )
   {
      if ( ActiveControl is RichTextBox r )
      {
         if ( keyData == ( Keys.Control | Keys.B ) )
         {
            r.SelectionFont = new Font( r.SelectionFont, r.SelectionFont.Style ^ FontStyle.Bold ); // XOR will toggle
            return true;
         }
         if ( keyData == ( Keys.Control | Keys.U ) )
         {
            r.SelectionFont = new Font( r.SelectionFont, r.SelectionFont.Style ^ FontStyle.Underline ); // XOR will toggle
            return true;
         }
         if ( keyData == ( Keys.Control | Keys.I ) )
         {
            r.SelectionFont = new Font( r.SelectionFont, r.SelectionFont.Style ^ FontStyle.Italic ); // XOR will toggle
            return true;
         }
      }
      return base.ProcessCmdKey( ref msg, keyData );
   }

There is already a Twig extension that lets you call PHP functions form your Twig templates like:

Hi, I am unique: {{ uniqid() }}.

And {{ floor(7.7) }} is floor of 7.7.

See official extension repository.

Do not assume your unix_socket which would be different from one to another, try to find it.

First of all, get your unix_socket location.

$ mysql -u root -p

Enter your mysql password and login your mysql server from command line.

mysql> show variables like '%sock%';
+---------------+---------------------------------------+
| Variable_name | Value                                 |
+---------------+---------------------------------------+
| socket        | /opt/local/var/run/mysql5/mysqld.sock |
+---------------+---------------------------------------+

Your unix_soket could be diffrent.

Then change your php.ini, find your php.ini file from

<? phpinfo();

You maybe install many php with different version, so please don't assume your php.ini file location, get it from your 'phpinfo';

Change your php.ini:

mysql.default_socket = /opt/local/var/run/mysql5/mysqld.sock

mysqli.default_socket = /opt/local/var/run/mysql5/mysqld.sock

pdo_mysql.default_socket = /opt/local/var/run/mysql5/mysqld.sock

Then restart your apache or php-fpm.

When multiple keys end up in same hash code which is present in same bucket. When the same key has different values then the old value will be replaced with new value.

Liked list converted to balanced Binary tree from java 8 version on wards in worst case scenario.

Collision happen when 2 distinct keys generate the same hashcode() value. When there are more collisions then there it will leads to worst performance of hashmap.

Objects which are are equal according to the equals method must return the same hashCode value. When both objects return the same has code then they will be moved into the same bucket.

try using

@record.assign_attributes({ ... })
@record.save(validate: false)

works for me

You can change it inside bs-config.json file as mentioned in the docs https://github.com/johnpapa/lite-server#custom-configuration

For example,

{
  "port": 8000,
  "files": ["./src/**/*.{html,htm,css,js}"],
  "server": { "baseDir": "./src" }
}

1. Netbeans allows you to do a simple filecopy. As you know, Eclipse doesn't work like that. You must explicitly "import" files and projects.

2. If you do import, and if there are no problems, then they should show up.

3. I'd consider:

   a) making a backup of your existing workspace

   b) deleting and reinstalling Eclipse

   c) Trying another "test import"

Sort and Lock Table is the only solution I have seen which does work on other browsers than IE. (although this "locked column css" might do the trick as well). Required code block below.

Generic Table Sort

Basic Concept: A table can be sorted by clicking on the title of any
column in the table, toggling between ascending and descending sorts.


Assumptions:

* The first row of the table contains column titles that are "clicked"
  to sort the table

* The images 'desc.gif','asc.gif','none.gif','sorting.gif' exist

* The img tag is in each column of the the title row to represent the
  sort graphic.

* The CSS classes 'alternateRow' and 'sortedColumn' exist so we can
  have alternating colors for each row and a highlight the sorted
  column.  Something like the <style> definition below, but with the
  background colors set to whatever you want.

   <style>
   tr.alternateRow {
     background-color: #E0F1E0;
   }

   td.sortedColumn {
     background-color: #E0F1E0;
   }

   tr.alternateRow td.sortedColumn {
     background-color: #c5e5c5;
   }
   </style>

====================================================== */

My Solution was to put a try catch, & is working fine

try {
this.Invoke(new EventHandler(DoUpdate)); }
catch { }

You can also use a combination of cat and paste0

cat(paste0("File not supplied.\n", "Usage: ./program F=filename"))

I find this to be more useful when incorporating variables into the printout. For example:

file <- "myfile.txt"
cat(paste0("File not supplied.\n", "Usage: ./program F=", file))

Apart from using @MvcHtmlString.Create(ViewBag.Stuff) as suggested by Dommer, I suggest you to also use AntiXSS library as suggested phill http://haacked.com/archive/2010/04/06/using-antixss-as-the-default-encoder-for-asp-net.aspx

It encodes almost all the possible XSS attack string.

You should initialize yours recordings. You are passing to adapter null

ArrayList<String> recordings = null; //You are passing this null

If you want get location of Database you can check Get All DBs Location.
you can use sys.master_files for get location of db and sys.databse to get db name

SELECT
    db.name AS DBName,
    type_desc AS FileType,
    Physical_Name AS Location
FROM
    sys.master_files mf
INNER JOIN 
    sys.databases db ON db.database_id = mf.database_id

I solved this in Windows 10 by running in admin Powershell:

cd "C:\Program Files\Docker\Docker"

And then:

./DockerCli.exe -SwitchDaemon

There are a number of things wrong with your code:

char *readFile(char *fileName)
{
    FILE *file;
    char *code = malloc(1000 * sizeof(char));
    file = fopen(fileName, "r");
    do 
    {
      *code++ = (char)fgetc(file);

    } while(*code != EOF);
    return code;
}

1. What if the file is greater than 1,000 bytes?
2. You are increasing code each time you read a character, and you return code back to the caller (even though it is no longer pointing at the first byte of the memory block as it was returned by malloc).
3. You are casting the result of fgetc(file) to char. You need to check for EOF before casting the result to char.

It is important to maintain the original pointer returned by malloc so that you can free it later. If we disregard the file size, we can achieve this still with the following:

char *readFile(char *fileName)
{
    FILE *file = fopen(fileName, "r");
    char *code;
    size_t n = 0;
    int c;

    if (file == NULL)
        return NULL; //could not open file

    code = malloc(1000);

    while ((c = fgetc(file)) != EOF)
    {
        code[n++] = (char) c;
    }

    // don't forget to terminate with the null character
    code[n] = '\0';        

    return code;
}

There are various system calls that will give you the size of a file; a common one is stat.

your form is missing the method...

<form name="registrationform" action="register.php" method="post"> //here

anywyas to check the posted data u can use isset()..

Determine if a variable is set and is not NULL

if(!isset($firstname) || trim($firstname) == '')
{
   echo "You did not fill out the required fields.";
}

Android does not support MySQL out of the box. The "normal" way to access your database would be to put a Restful server in front of it and use the HTTPS protocol to connect to the Restful front end.

Have a look at ContentProvider. It is normally used to access a local database (SQLite) but it can be used to get data from any data store.

I do recommend that you look at having a local copy of all/some of your websites data locally, that way your app will still work when the Android device hasn't got a connection. If you go down this route then a service can be used to keep the two databases in sync.

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

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

Kotlin version:

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

Hope this helps.

I prefer using linq-to-json feature of JSON.NET framework. Here's how you can serialize a list of your objects to json.

List<MyObject> list = new List<MyObject>();

Func<MyObject, JObject> objToJson =
    o => new JObject(
            new JProperty("ObjectId", o.ObjectId), 
            new JProperty("ObjectString", o.ObjectString));

string result = new JObject(new JArray(list.Select(objToJson))).ToString();

You fully control what will be in the result json string and you clearly see it just looking at the code. Surely, you can get rid of Func<T1, T2> declaration and specify this code directly in the new JArray() invocation but with this code extracted to Func<> it looks much more clearer what is going on and how you actually transform your object to json. You can even store your Func<> outside this method in some sort of setup method (i.e. in constructor).

I went over most of the answers here and none of them gave me the right user name.

In my case I wanted to get the logged in user name, while running my app from a different user, like when shift+right click on a file and "Run as a different user".

The answers I tried gave me the 'other' username.

This blog post supplies a way to get the logged in user name, which works even in my scenario:
https://smbadiwe.github.io/post/track-activities-windows-service/

It uses Wtsapi

Probably because the original version of Python (CPython) was written in C, not C++.

The idea that a list is formed by pushing things onto the back of something is probably not as well-known as the thought of appending them.

You can also do something like that:

<error-page>
    <error-code>403</error-code>
    <location>/403.html</location>
</error-page>

<error-page>
    <location>/error.html</location>
</error-page>

For error code 403 it will return the page 403.html, and for any other error code it will return the page error.html.

I know this is an old question but I needed a formula for workdays excluding the start date since I have several items and need the days to accumulate correctly.

None of the non-iterative answers worked for me.

I used a defintion like

Number of times midnight to monday, tuesday, wednesday, thursday and friday is passed

(others might count midnight to saturday instead of monday)

I ended up with this formula

SELECT DATEDIFF(day, @StartDate, @EndDate) /* all midnights passed */
     - DATEDIFF(week, @StartDate, @EndDate) /* remove sunday midnights */
     - DATEDIFF(week, DATEADD(day, 1, @StartDate), DATEADD(day, 1, @EndDate)) /* remove saturday midnights */

Internally, .bind maps directly to .on in the current version of jQuery. (The same goes for .live.) So there is a tiny but practically insignificant performance hit if you use .bind instead.

However, .bind may be removed from future versions at any time. There is no reason to keep using .bind and every reason to prefer .on instead.

I need to see your submit button html tag for better help. I am not familiar with php and how it handles the postback, but I guess depending on what you want to do, you have three options:

1. Getting the handling onclick button on the client-side: In this case you only need to call a javascript function.

function foo() {_x000D_
   alert("Submit button clicked!");_x000D_
   return true;_x000D_
}

<input type="submit" value="submit" onclick="return foo();" />

2. If you want to handle the click on the server-side, you should first make sure that the form tag method attribute is set to post:

   <form method="post">
   

3. You can use onsubmit event from form itself to bind your function to it.

<form name="frm1" method="post" onsubmit="return greeting()">_x000D_
    <input type="text" name="fname">_x000D_
    <input type="submit" value="Submit">_x000D_
</form>

This can be done by calling the reload() method of the window object in plain JavaScript

window.location.reload();

To answer the question : if you want to exclude certain files of a checkout, you can use sparse-checkout

1. In .git/info/sparse-checkout, define what you want to keep. Here, we want all (*) but (note the exclamation mark) config.php :

   /* !/config.php

2. Tell git you want to take sparse-checkout into account

   git config core.sparseCheckout true

3. If you already have got this file locally, do what git does on a sparse checkout (tell it it must exclude this file by setting the "skip-worktree" flag on it)

   git update-index --skip-worktree config.php

4. Enjoy a repository where your config.php file is yours - whatever changes are on the repository.

Please note that configuration values SHOULDN'T be in source control :

• It is a potential security breach
• It causes problems like this one for deployment

This means you MUST exclude them (put them in .gitignore before first commit), and create the appropriate file on each instance where you checkout your app (by copying and adapting a "template" file)

Note that, once a file is taken in charge by git, .gitignore won't have any effect.

Given that, once the file is under source control, you only have two choices () :

• rebase all your history to remove the file (with git filter-branch)

• create a commit that removes the file. It is like fighting a loosing battle, but, well, sometimes you have to live with that.

XCACLS.VBS is a very powerful script that will change/edit ACL info. c:\windows\system32\cscript.exe xcacls.vbs help returns all switches and options.

You can get official distribution from Microsoft Support Page

Try this

After selecting a block of text, press Shift+i or capital I.

Lowercase i will not work.

Then type the things you want and finally to apply it to all lines, press Esc twice.

If this doesn't work...

Check if you have +visualextra enabled in your version of Vim.

You can do this by typing in :ver and scrolling through the list of features. (You might want to copy and paste it into a buffer and do incremental search because the format is odd.)

Enabling it is outside the scope of this question but I'm sure you can find it somewhere.

span element is display:inline; by default you need to make it inline-block or block

Change your CSS to be like this

span.first_title {
    margin-top: 20px;
    margin-left: 12px;
    font-weight: bold;
    font-size:24px;
    color: #221461;
    /*The change*/
    display:inline-block; /*or display:block;*/
}

Section 2 of RFC 2368 says that the body field is supposed to be in text/plain format, so you can't do HTML.

However even if you use plain text it's possible that some modern mail clients would render a URL as a clickable link anyway, though.

If you really need to use an array instead of a list, then you can create an array whose size is calculated at run time like so...

e.g i want a two dimensional array of size n by n. n will be gotten at run time from the user

int n = 0;
bool isInteger = int.TryPase(Console.ReadLine(), out n);
var x = new int[n,n];

On the one hand, throwing exceptions is inherently expensive, because the stack has to be unwound etc.
On the other hand, accessing a value in a dictionary by its key is cheap, because it's a fast, O(1) operation.

BTW: The correct way to do this is to use TryGetValue

obj item;
if(!dict.TryGetValue(name, out item))
    return null;
return item;

This accesses the dictionary only once instead of twice.
If you really want to just return null if the key doesn't exist, the above code can be simplified further:

obj item;
dict.TryGetValue(name, out item);
return item;

This works, because TryGetValue sets item to null if no key with name exists.

Well, maybe an int does not posses the len attribute in Python like your error suggests?

Try:

len(str(numbers))

The below C++ solution obtained a 100% score. The theoretical complexity of the code is. Time Complexity : O(N) amortized due to hash set and Auxiliary Space complexity of O(N) due to use of hash for lookup in O(1) time.

#include<iostream>
#include<string>
#include<vector>
#include<climits>
#include<cmath>
#include<unordered_set>

using namespace std;

int solution(vector<int>& A)
{
  if(!A.size())
    return(1);

  unordered_set<int> hashSet;
  int maxItem=INT_MIN;
  for(const auto& item : A)
  {
    hashSet.insert(item);
    if(maxItem<item)
      maxItem=item;
  }

  if(maxItem<1)
    return(1);

  for(int i=1;i<=maxItem;++i)
  {
    if(hashSet.find(i)==hashSet.end())
      return(i);
  }
  return(maxItem+1);
}

I think there are three key items you need to understand regarding project structure: Targets, projects, and workspaces. Targets specify in detail how a product/binary (i.e., an application or library) is built. They include build settings, such as compiler and linker flags, and they define which files (source code and resources) actually belong to a product. When you build/run, you always select one specific target.

It is likely that you have a few targets that share code and resources. These different targets can be slightly different versions of an app (iPad/iPhone, different brandings,…) or test cases that naturally need to access the same source files as the app. All these related targets can be grouped in a project. While the project contains the files from all its targets, each target picks its own subset of relevant files. The same goes for build settings: You can define default project-wide settings in the project, but if one of your targets needs different settings, you can always override them there:

Shared project settings that all targets inherit, unless they override it

Concrete target settings: PSE iPhone overrides the project’s Base SDK setting

In Xcode, you always open projects (or workspaces, but not targets), and all the targets it contains can be built/run, but there’s no way/definition of building a project, so every project needs at least one target in order to be more than just a collection of files and settings.

Select one of the project’s targets to run

In a lot of cases, projects are all you need. If you have a dependency that you build from source, you can embed it as a subproject. Subprojects can be opened separately or within their super project.

demoLib is a subproject

If you add one of the subproject’s targets to the super project’s dependencies, the subproject will be automatically built unless it has remained unchanged. The advantage here is that you can edit files from both your project and your dependencies in the same Xcode window, and when you build/run, you can select from the project’s and its subprojects’ targets:

If, however, your library (the subproject) is used by a variety of other projects (or their targets, to be precise), it makes sense to put it on the same hierarchy level – that’s what workspaces are for. Workspaces contain and manage projects, and all the projects it includes directly (i.e., not their subprojects) are on the same level and their targets can depend on each other (projects’ targets can depend on subprojects’ targets, but not vice versa).

Workspace structure

In this example, both apps (AnotherApplication / ProjectStructureExample) can reference the demoLib project’s targets. This would also be possible by including the demoLib project in both other projects as a subproject (which is a reference only, so no duplication necessary), but if you have lots of cross-dependencies, workspaces make more sense. If you open a workspace, you can choose from all projects’ targets when building/running.

You can still open your project files separately, but it is likely their targets won’t build because Xcode cannot resolve the dependencies unless you open the workspace file. Workspaces give you the same benefit as subprojects: Once a dependency changes, Xcode will rebuild it to make sure it’s up-to-date (although I have had some issues with that, it doesn’t seem to work reliably).

Your questions in a nutshell:

1) Projects contain files (code/resouces), settings, and targets that build products from those files and settings. Workspaces contain projects which can reference each other.

2) Both are responsible for structuring your overall project, but on different levels.

3) I think projects are sufficient in most cases. Don’t use workspaces unless there’s a specific reason. Plus, you can always embed your project in a workspace later.

4) I think that’s what the above text is for…

There’s one remark for 3): CocoaPods, which automatically handles 3rd party libraries for you, uses workspaces. Therefore, you have to use them, too, when you use CocoaPods (which a lot of people do).

You could create a user form:

http://www.excel-vba-easy.com/vba-userform-excel-vba.html

I had two request URIs in the Console, http://xxxxx/client/api/spreadsheet/authredirect and http://localhost.

I tried all the top responses to this question and confirmed that none of them were my problem.

I removed localhost from the Console, updated my client_secret.json in my project, and the mismatch error went away.

In android studio you can do single comment with (go to line then Ctrl+/) and block comment with ( select text then Ctrl+Shift+/)

Also if you want to change color of commented text go to File->Settings->IDE settings->Editor->Color & fonts->Java->(Line comment or block comment) and change properties. I prefer it to be green which is used in notepad++ editor.

I had this problem on Mac OS X. We don't have a /proc virtual file system, so the accepted solution cannot work.

We do, instead, have a F_GETPATH command for fcntl:

 F_GETPATH          Get the path of the file descriptor Fildes.  The argu-
                    ment must be a buffer of size MAXPATHLEN or greater.

So to get the file associated to a file descriptor, you can use this snippet:

#include <sys/syslimits.h>
#include <fcntl.h>

char filePath[PATH_MAX];
if (fcntl(fd, F_GETPATH, filePath) != -1)
{
    // do something with the file path
}

Since I never remember where MAXPATHLEN is defined, I thought PATH_MAX from syslimits would be fine.

You need to do .button("refresh")

HTML :

<button id='btnviewdetails' type='button'>SET</button>

JS :

$('#btnviewdetails').text('Save').button("refresh");

use

header("Location: index.php"); //this work in my site

read more on header() at php documentation.

Ctrl-Alt-X is the keyboard shortcut I use, although that may because I have Resharper installed - otherwise Ctrl W, X.

To anyone still struggling to get the os.environ solution to work as I was, check that this is placed before you import tensorflow in your script, just like mwweb's answer:

os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3'  # or any {'0', '1', '2'}
import tensorflow as tf

I am storing a class object into a string using toString() method. Now, I want to convert the string into that class object.

Your question is ambiguous. It could mean at least two different things, one of which is ... well ... a serious misconception on your part.

If you did this:

SomeClass object = ...
String s = object.toString();

then the answer is that there is no simple way to turn s back into an instance of SomeClass. You couldn't do it even if the toString() method gave you one of those funky "SomeClass@xxxxxxxx" strings. (That string does not encode the state of the object, or even a reference to the object. The xxxxxxxx part is the object's identity hashcode. It is not unique, and cannot be magically turned back into a reference to the object.)

The only way you could turn the output of toString back into an object would be to:

• code the SomeClass.toString() method so that included all relevant state for the object in the String it produced, and
• code a constructor or factory method that explicitly parsed a String in the format produced by the toString() method.

This is probably a bad approach. Certainly, it is a lot of work to do this for non-trivial classes.

If you did something like this:

SomeClass object = ...
Class c = object.getClass();
String cn = c.toString();

then you could get the same Class object back (i.e. the one that is in c) as follows:

Class c2 = Class.forName(cn);

This gives you the Class but there is no magic way to reconstruct the original instance using it. (Obviously, the name of the class does not contain the state of the object.)

If you are looking for a way to serialize / deserialize an arbitrary object without going to the effort of coding the unparse / parse methods yourself, then you shouldn't be using toString() method at all. Here are some alternatives that you can use:

• The Java Object Serialization APIs as described in the links in @Nishant's answer.
• JSON serialization as described in @fatnjazzy's answer.
• An XML serialization library like XStream.
• An ORM mapping.

Each of these approaches has advantages and disadvantages ... which I won't go into here.

I switched over to the managed ODP.NET assemblies from Oracle. I also had to purge all the files from the IIS web apps that were using the older assemblies. Now I don't get any conflicts regarding 32 vs 64 bit versions when I debug in IIS Express vs IIS. See the following article.

An Easy Drive to .NET

Say you had some URL that gave you JSON data like:

{'field': 'value'}

...and you had a similar URL except it used JSONP, to which you passed the callback function name 'myCallback' (usually done by giving it a query parameter called 'callback', e.g. http://example.com/dataSource?callback=myCallback). Then it would return:

myCallback({'field':'value'})

...which is not just an object, but is actually code that can be executed. So if you define a function elsewhere in your page called myFunction and execute this script, it will be called with the data from the URL.

The cool thing about this is: you can create a script tag and use your URL (complete with callback parameter) as the src attribute, and the browser will run it. That means you can get around the 'same-origin' security policy (because browsers allow you to run script tags from sources other than the domain of the page).

This is what jQuery does when you make an ajax request (using .ajax with 'jsonp' as the value for the dataType property). E.g.

$.ajax({
  url: 'http://example.com/datasource',
  dataType: 'jsonp',

});

Here, jQuery takes care of the callback function name and query parameter - making the API identical to other ajax calls. But unlike other types of ajax requests, as mentioned, you're not restricted to getting data from the same origin as your page.

The reason for the error is that the nextInt only pulls the integer, not the newline. If you add a in.nextLine() before your for loop, it will eat the empty new line and allow you to enter 3 names.

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = in.nextInt();

names = new String[nnames];
in.nextLine();
for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

or just read the line and parse the value as an Integer.

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = Integer.parseInt(in.nextLine().trim());

names = new String[nnames];
for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

You need to tag your image correctly first with your registryhost:

docker tag [OPTIONS] IMAGE[:TAG] [REGISTRYHOST/][USERNAME/]NAME[:TAG]

Then docker push using that same tag.

docker push NAME[:TAG]

Example:

docker tag 518a41981a6a myRegistry.com/myImage
docker push myRegistry.com/myImage

A little error checking goes a long way -- you can always test the value of errno or call perror() or strerror() to get more information about why the fopen() call failed.

Otherwise the suggestions about checking the path are probably correct... most likely you're not in the directory you think you are from the IDE and don't have the permissions you expect.

Your query contains columns which could be present with the same name in more than one table you are referencing, hence the not unique error. It's best if you make the references explicit and/or use table aliases when joining.

Try

    SELECT pa.ProjectID, p.Project_Title, a.Account_ID, a.Username, a.Access_Type, c.First_Name, c.Last_Name
      FROM Project_Assigned pa
INNER JOIN Account a
        ON pa.AccountID = a.Account_ID
INNER JOIN Project p
        ON pa.ProjectID = p.Project_ID
INNER JOIN Clients c
        ON a.Account_ID = c.Account_ID
     WHERE a.Access_Type = 'Client';

I've tried this and it worked for me,

This code works for me. I used it into my application in ajax.

history.pushState({ foo: 'bar' }, '', '/bank');

Once a page load into an ID using ajax, It does change the browser url automatically without reloading the page.

This is ajax function bellow.

function showData(){
    $.ajax({
      type: "POST",
      url: "Bank.php", 
      data: {}, 
      success: function(html){          
        $("#viewpage").html(html).show();
        $("#viewpage").css("margin-left","0px");
      }
    });
  }

Example: From any page or controller like "Dashboard", When I click on the bank, it loads bank list using the ajax code without reloading the page. At this time, browser URL will not be changed.

history.pushState({ foo: 'bar' }, '', '/bank');

But when I use this code into the ajax, it change the browser url without reloading the page. This is the full ajax code here in the bellow.

function showData(){
        $.ajax({
          type: "POST",
          url: "Bank.php", 
          data: {}, 
          success: function(html){          
            $("#viewpage").html(html).show();
            $("#viewpage").css("margin-left","0px");
            history.pushState({ foo: 'bar' }, '', '/bank');
          }
        });
      }

Submodules parallel fetch aims at reducing the time required to fetch a repositories and all of its related submodules by enabling the fetching of multiple repositories at once. This can be accomplished by using the new --jobs option, e.g.:

git fetch --recurse-submodules --jobs=4

According to Git team, this can substantially speed up updating repositories that contain many submodules. When using --recurse-submodules without the new --jobs option, Git will fetch submodules one by one.

If you get this error message from the browser:

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '…' is therefore not allowed access

when you're trying to do an Ajax POST/GET request to a remote server which is out of your control, please forget about this simple fix:

<?php header('Access-Control-Allow-Origin: *'); ?>

What you really need to do, especially if you only use JavaScript to do the Ajax request, is an internal proxy who takes your query and send it through to the remote server.

First in your JavaScript, do an Ajax call to your own server, something like:

$.ajax({
    url: yourserver.com/controller/proxy.php,
    async:false,
    type: "POST",
    dataType: "json",
    data: data,
    success: function (result) {
        JSON.parse(result);
    },
    error: function (xhr, ajaxOptions, thrownError) {
        console.log(xhr);
    }
});

Then, create a simple PHP file called proxy.php to wrap your POST data and append them to the remote URL server as a parameters. I give you an example of how I bypass this problem with the Expedia Hotel search API:

if (isset($_POST)) {
  $apiKey = $_POST['apiKey'];
  $cid = $_POST['cid'];
  $minorRev = 99;

  $url = 'http://api.ean.com/ean-services/rs/hotel/v3/list?' . 'cid='. $cid . '&' . 'minorRev=' . $minorRev . '&' . 'apiKey=' . $apiKey;

  echo json_encode(file_get_contents($url));
 }

By doing:

 echo json_encode(file_get_contents($url));

You are just doing the same query but on the server side and after that, it should works fine.

I think this should help you.

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0">

Tell me if it works.

P/s: here is some media query for standard devices. http://css-tricks.com/snippets/css/media-queries-for-standard-devices/

You must create them under strings.xml

<string name="close">Close</string>    

You must replace and reference like this

android:text="@string/close"/>

Do not use @strings even though the XML file says strings.xml or else it will not work.

You can also add underscore.js to your project and will be able to do it in one line:

_.map($("input[name='category_ids[]']:checked"), function(el){return $(el).val()})

If you want to have a dynamic function like the __call function in PHP, you could use Proxies.

const target = {};

const handler = {
  get: function (target, name) {
    return (myArg) => {
      return new Promise(resolve => setTimeout(() => resolve('some' + myArg), 600))
    }
  }
};

const proxy = new Proxy(target, handler);

(async function() {
  const result = await proxy.foo('string')
  console.log('result', result) // 'result somestring' after 600 ms
})()

It means your Java runtime version is 1.8, but your compiler version (javac) is 1.6. To simply solve it, just retreat the Java version from 1.8 to 1.6.

But if you don't want to change the Java runtime version, then do the following steps:

1. JAVA_HOME= "your jdk v1.8 folder path", to make sure jdk is also v1.8 and use java -version and javac -version again to ensure it
2. Make sure IntelliJ 's compiler mode is set to compliant with v1.6 But i have tried that. it didn't solve my problem.

In PostGIS Geometry is preferred over Geography (round earth model) because the computations are much simpler therefore faster. It also has MANY more available functions but is less accurate over very long distances.

Import your CSV long and lat fields to DECIMAL(10,6) columns. 6 digits is 10cm precision, should be plenty for most use cases. Then cast your imported data to the correct SRID

The wrong way!

/* try what seems the obvious solution */
DROP TABLE IF EXISTS public.test_geom_bad;
-- Big Ben, London
SELECT ST_SetSRID(ST_MakePoint(-0.116773, 51.510357),4326) AS geom
INTO public.test_geom_bad;

The CORRECT way

/* add the necessary CAST to make it work */
DROP TABLE IF EXISTS public.test_geom_correct;
SELECT ST_SetSRID(ST_MakePoint(-0.116773, 51.510357),4326)::geometry(Geometry, 4326) AS geom
INTO public.test_geom_correct;

Verify SRID is not zero!

/* now observe the incorrect SRID 0 */
SELECT * FROM public.geometry_columns
WHERE f_table_name IN ('test_geom_bad','test_geom_correct');

Validate the order of your long lat parameter using a WKT viewer and

SELECT ST_AsEWKT(geom) FROM public.test_geom_correct

Then index it for best performance

CREATE INDEX idx_target_table_geom_gist
    ON target_table USING gist(geom);

That's simple. It's explained in man bash:

/bin/bash
       The bash executable
/etc/profile
       The systemwide initialization file, executed for login shells
~/.bash_profile
       The personal initialization file, executed for login shells
~/.bashrc
       The individual per-interactive-shell startup file
~/.bash_logout
       The individual login shell cleanup file, executed when a login shell exits
~/.inputrc
       Individual readline initialization file

Login shells are the ones that are read one you login (so, they are not executed when merely starting up xterm, for example). There are other ways to login. For example using an X display manager. Those have other ways to read and export environment variables at login time.

Also read the INVOCATION chapter in the manual. It says "The following paragraphs describe how bash executes its startup files.", i think that's a spot-on :) It explains what an "interactive" shell is too.

Bash does not know about .environment. I suspect that's a file of your distribution, to set environment variables independent of the shell that you drive.

Try this:

1. Select the whole column
2. Click Format
3. Click Conditional formatting
4. Click Add another rule (or edit the existing/default one)
5. Set Format cells if to: Custom formula is
6. Set value to: =countif(A:A,A1)>1 (or change A to your chosen column)
7. Set the formatting style.
8. Ensure the range applies to your column (e.g., A1:A100).
9. Click Done

Anything written in the A1:A100 cells will be checked, and if there is a duplicate (occurs more than once) then it'll be coloured.

For locales using comma (,) as a decimal separator, the argument separator is most likely a semi-colon (;). That is, try: =countif(A:A;A1)>1, instead.

For multiple columns, use countifs.

Just move the extra condition into the JOIN ON criteria, this way the existence of b is not required to return a result

SELECT a.* FROM a 
    LEFT JOIN b ON a.group_id=b.group_id AND b.user_id!=$_SESSION{['user_id']} 
    WHERE a.keyword LIKE '%".$keyword."%' 
    GROUP BY group_id

Most of the time req.body is undefined due to missing JSON parser

const express = require('express');
app.use(express.json());

could be missing for the body-parser

const bodyParser  = require('body-parser');
app.use(bodyParser.urlencoded({extended: true}));

and sometimes it's undefined due to cros origin so add them

const cors = require('cors');
app.use(cors())

I think it isn't bad idea to use get_object_or_404()

from django.shortcuts import get_object_or_404

def my_view(request):
    my_object = get_object_or_404(MyModel, pk=1)

This example is equivalent to:

from django.http import Http404

def my_view(request):
    try:
        my_object = MyModel.objects.get(pk=1)
    except MyModel.DoesNotExist:
        raise Http404("No MyModel matches the given query.")

You can read more about get_object_or_404() in django online documentation.

Use the LEN function:

Returns the number of characters of the specified string expression, excluding trailing blanks.

fade's answer worked for me. I moved from 8.0.30 to 8.5.5 and the difference was the valve in <8.0.30>/manager/META-INF/context.xml was already commented out from the tar file but was uncommented in 8.5.5 tar.

I failed to read this important message in the 403 response:

By default the Manager is only accessible from a browser running on the same machine as Tomcat. If you wish to modify this restriction, you'll need to edit the Manager's context.xml file.

And failed to read this too:

Since r1734267 a RemoteAddrValve.is configured by default in Manager and HostManager web applications. This feature is present in 9.0.0.M4 and 8.5.0 onwards.

If you want to define your ItemReader instance and your Step instance in a single JavaConfig class. You can use the @StepScope and the @Value annotations such as:

@Configuration
public class ContributionCardBatchConfiguration {

   private static final String WILL_BE_INJECTED = null;

   @Bean
   @StepScope
   public FlatFileItemReader<ContributionCard> contributionCardReader(@Value("#{jobParameters['fileName']}")String contributionCardCsvFileName){

     ....
   }

   @Bean
   Step ingestContributionCardStep(ItemReader<ContributionCard> reader){
         return stepBuilderFactory.get("ingestContributionCardStep")
                 .<ContributionCard, ContributionCard>chunk(1)
                 .reader(contributionCardReader(WILL_BE_INJECTED))
                 .writer(contributionCardWriter())
                 .build();
    }
}

The trick is to pass a null value to the itemReader since it will be injected through the @Value("#{jobParameters['fileName']}") annotation.

Assuming that I is your input image and F is its Fourier Transform (i.e. F = fft2(I))

You can use this code:

F = fftshift(F); % Center FFT

F = abs(F); % Get the magnitude
F = log(F+1); % Use log, for perceptual scaling, and +1 since log(0) is undefined
F = mat2gray(F); % Use mat2gray to scale the image between 0 and 1

imshow(F,[]); % Display the result

Instead of using align-self: center use align-items: center.

There's no need to change flex-direction or use text-align.

Here's your code, with one adjustment, to make it all work:

ul {
  height: 100%;
}

li {
  display: flex;
  justify-content: center;
  /* align-self: center;    <---- REMOVE */
  align-items: center;   /* <---- NEW    */
  background: silver;
  width: 100%;
  height: 20%; 
}

The align-self property applies to flex items. Except your li is not a flex item because its parent – the ul – does not have display: flex or display: inline-flex applied.

Therefore, the ul is not a flex container, the li is not a flex item, and align-self has no effect.

The align-items property is similar to align-self, except it applies to flex containers.

Since the li is a flex container, align-items can be used to vertically center the child elements.

* {_x000D_
  padding: 0;_x000D_
  margin: 0;_x000D_
}_x000D_
html, body {_x000D_
  height: 100%;_x000D_
}_x000D_
ul {_x000D_
  height: 100%;_x000D_
}_x000D_
li {_x000D_
  display: flex;_x000D_
  justify-content: center;_x000D_
  /* align-self: center; */_x000D_
  align-items: center;_x000D_
  background: silver;_x000D_
  width: 100%;_x000D_
  height: 20%;_x000D_
}

<ul>_x000D_
  <li>This is the text</li>_x000D_
</ul>

codepen demo

Technically, here's how align-items and align-self work...

The align-items property (on the container) sets the default value of align-self (on the items). Therefore, align-items: center means all flex items will be set to align-self: center.

But you can override this default by adjusting the align-self on individual items.

For example, you may want equal height columns, so the container is set to align-items: stretch. However, one item must be pinned to the top, so it is set to align-self: flex-start.

example

How is the text a flex item?

Some people may be wondering how a run of text...

<li>This is the text</li>

is a child element of the li.

The reason is that text that is not explicitly wrapped by an inline-level element is algorithmically wrapped by an inline box. This makes it an anonymous inline element and child of the parent.

From the CSS spec:

9.2.2.1 Anonymous inline boxes

Any text that is directly contained inside a block container element must be treated as an anonymous inline element.

The flexbox specification provides for similar behavior.

4. Flex Items

Each in-flow child of a flex container becomes a flex item, and each contiguous run of text that is directly contained inside a flex container is wrapped in an anonymous flex item.

Hence, the text in the li is a flex item.

I know this question is for Bootstrap 3 but if you are looking solution for Bootstrap 4, just do this:

$(document).on('click','.navbar-collapse.show',function(e) {
  $(this).collapse('hide');
});

A clean solution could be create a generic class to handle the list, so you don't need to create a different class each time you need it.

public class ListModel<T>
{
    public List<T> Items { get; set; }

    public ListModel(List<T> list) {
        Items = list;
    }
}

and when you return the View you just need to simply do:

List<customClass> ListOfCustomClass = new List<customClass>();
//Do as needed...
return View(new ListModel<customClass>(ListOfCustomClass));

then define the list in the model:

@model ListModel<customClass>

and ready to go:

@foreach(var element in Model.Items) {
  //do as needed...
}

This worked fine !

You're not assigning any id to the text view, but you're using tv.getId() to pass it to the addRule method as a parameter. Try to set a unique id via tv.setId(int).

You could also use the LinearLayout with vertical orientation, that might be easier actually. I prefer LinearLayout over RelativeLayouts if not necessary otherwise.

You must use "npm config set http-proxy"

use:

npm config set http-proxy http://1.2.3.4:8181
npm config set https-proxy http://1.2.3.4:8181

document.location.href = newUrl;

Try installing this, it's a known workaround for enabling the C++ compiler for Python 2.7.

In my experience, when pip does not find vcvarsall.bat compiler, all I do is opening a Visual Studio console as it set the path variables to call vcvarsall.bat directly and then I run pip on this command line.

Combine them. Literally combine them; attach them together without any punctuation.

$('.myclass[reference="12345"]')

Your first selector looks for elements with the attribute value, contained in elements with the class.
The space is being interpreted as the descendant selector.

Your second selector, like you said, looks for elements with either the attribute value, or the class, or both.
The comma is being interpreted as the multiple selector operator — whatever that means (CSS selectors don't have a notion of "operators"; the comma is probably more accurately known as a delimiter).

The string has a substring method that returns the string at the specified position.

String name="123456789";
System.out.println(name.substring(0,1));

gcc and g++ are compiler-drivers of the GNU Compiler Collection (which was once upon a time just the GNU C Compiler).

Even though they automatically determine which backends (cc1 cc1plus ...) to call depending on the file-type, unless overridden with -x language, they have some differences.

The probably most important difference in their defaults is which libraries they link against automatically.

According to GCC's online documentation link options and how g++ is invoked, g++ is equivalent to gcc -xc++ -lstdc++ -shared-libgcc (the 1st is a compiler option, the 2nd two are linker options). This can be checked by running both with the -v option (it displays the backend toolchain commands being run).

Have look at WebLookAndFeel at https://github.com/mgarin/weblaf/

WebTextField txtName = new com.alee.laf.text.WebTextField();

txtName.setHideInputPromptOnFocus(false);

txtName.setInputPrompt("Name");

txtName.setInputPromptFont(new java.awt.Font("Ubuntu", 0, 18));

txtName.setInputPromptForeground(new java.awt.Color(102, 102, 102));

txtName.setInputPromptPosition(0);

Currently it only works for the .dropdown-menu:

.dropdown-menu .divider {
  height: 1px;
  margin: 9px 0;
  overflow: hidden;
  background-color: #e5e5e5;
}

If you want it for other use, in your own css, following the bootstrap.css create another one:

.divider {
  height: 1px;
  width:100%;
  display:block; /* for use on default inline elements like span */
  margin: 9px 0;
  overflow: hidden;
  background-color: #e5e5e5;
}

I'm leaving the below post for reference purposes.

July 2012 - As this reply is rather old, but stills seems popular. I've written a blog post based on Apple's doco and placed it on my blog. I hope you guys find it useful.

Yes. In iPhone/iPad development the Default.png file is displayed by the device automatically so you don't have to program it which is really useful. I don't have it with me, but you need different PNGs for the iPad with specific names. I googled iPad default png and got this info from the phunkwerks site:

iPad Launch Image Orientations

To deal with various orientation options, a new naming convention has been created for iPad launch images. The screen size of the iPad is 768×1024, notice in the dimensions that follow the height takes into account a 20 pixel status bar.

Filename Dimensions

• Default-Portrait.png * — 768w x 1024h
• Default-PortraitUpsideDown.png — 768w x 1024h
• Default-Landscape.png ** — 1024w x 748h
• Default-LandscapeLeft.png — 1024w x 748h
• Default-LandscapeRight.png — 1024w x 748h
• iPad-Retina–Portrait.png — 1536w x 2048h
• iPad-Retina–Landscape.png — 2048w x 1496h
• Default.png — Not recommended

*—If you have not specified a Default-PortraitUpsideDown.png file, this file will take precedence.

**—If you have not specified a Default-LandscapeLeft.png or Default-LandscapeRight.png image file, this file will take precedence.

This link to "Apple's Developer Library" is useful, too.

It may be helpful to make an alias for it.

Install and find your tensorboard location:

pip install tensorboard
pip show tensorboard

Add the following alias in .bashrc:

alias tensorboard='python pathShownByPip/tensorboard/main.py'

Open another terminal or run exec bash.

For Windows users, cd into pathShownByPip\tensorboard and run python main.py from there.

For Python 3.x, use pip3 instead of pip, and don't forget to use python3 in the alias.

For people familiar with GIT, master in GIT is equivalent to trunk in SVN.

Branch and tag has same terminology in both GIT and SVN.

On the Git branch, run:

git branch -m old_name  new_name

This will modify the branch name on your local repository:

git push origin :old_name new_name

This will push the modified name to the remote and delete the old branch:

git push origin -u new_name

It sets the local branch to track the remote branch.

This solves the issue.

all inputs:

var inputs = $("#formId :input");

all buttons

var button = $("#formId :button")

There should be only one localhost defined, check sites-enabled or nginx.conf.

You could use an OrderedDictionary, but I would question why you would want to do that.

First, don't. Avoid this sort of code. It tends to be really bad code and insecure too (see section 6 of Secure Coding Guidelines for the Java Programming Language, version 2.0).

If you must do it, prefer java.beans to reflection. Beans wraps reflection allowing relatively safe and conventional access.

Instead of running perror on any error code you get, you can retrieve a complete listing of errno values on your system with the following one-liner:

cpp -dM /usr/include/errno.h | grep 'define E' | sort -n -k 3

This should get the id added.

ASP.NET MVC 5 and lower:

<% using (Html.BeginForm(null, null, FormMethod.Post, new { id = "signupform" }))
   { } %>

ASP.NET Core: You can use tag helpers in forms to avoid the odd syntax for setting the id.

<form asp-controller="Account" asp-action="Register" method="post" id="signupform" role="form"></form>

if all your value are positive, you can do -max(-n)

Strong pattern matching — This is the method that I use here at Perishable Press. Using strong pattern matching, this technique prevents external access to any file containing “.hta”, “.HTA”, or any case-insensitive combination thereof. To illustrate, this code will prevent access through any of the following requests:

• .htaccess
• .HTACCESS
• .hTaCcEsS
• testFILE.htaccess
• filename.HTACCESS
• FILEROOT.hTaCcEsS

..etc., etc. Clearly, this method is highly effective at securing your site’s HTAccess files. Further, this technique also includes the fortifying “Satisfy All” directive. Note that this code should be placed in your domain’s root HTAccess file:

# STRONG HTACCESS PROTECTION
<Files ~ "^.*\.([Hh][Tt][Aa])">
order allow,deny
deny from all
satisfy all
</Files>

Support, unfortunately, is brutal at best. Here's a post on the topic:

https://www.campaignmonitor.com/blog/email-marketing/2013/02/embedded-images-in-html-email/

And the post content:

If you want to change the range to [0, 1], make sure the output data type is float.

image = cv2.imread("lenacolor512.tiff", cv2.IMREAD_COLOR)  # uint8 image
norm_image = cv2.normalize(image, None, alpha=0, beta=1, norm_type=cv2.NORM_MINMAX, dtype=cv2.CV_32F)

eclipse -clean did not work but following did

eclipse -clean -clearPersistedState

Update MyTable
Set Value = (
                Select Min( T2.Value )
                From MyTable As T2
                Where T2.Id <> MyTable.Id
                    And T2.Name = MyTable.Name
                )
Where ( Value Is Null Or Value = '' )
    And Exists  (
                Select 1
                From MyTable As T3
                Where T3.Id <> MyTable.Id
                    And T3.Name = MyTable.Name
                )

Add another option, maybe not the most lightweight.

solution that worked for me is to change user under which Application Pool is started (ApplicationPoolIdentity obviously has not enough rights to access COM object).

Good luck!

TL;DR

Error #1064 means that MySQL can't understand your command. To fix it:

• Read the error message. It tells you exactly where in your command MySQL got confused.

• Examine your command. If you use a programming language to create your command, use echo, console.log(), or its equivalent to show the entire command so you can see it.

• Check the manual. By comparing against what MySQL expected at that point, the problem is often obvious.

• Check for reserved words. If the error occurred on an object identifier, check that it isn't a reserved word (and, if it is, ensure that it's properly quoted).

1. Aaaagh!! What does #1064 mean?

   Error messages may look like gobbledygook, but they're (often) incredibly informative and provide sufficient detail to pinpoint what went wrong. By understanding exactly what MySQL is telling you, you can arm yourself to fix any problem of this sort in the future.

   As in many programs, MySQL errors are coded according to the type of problem that occurred. Error #1064 is a syntax error.

   • What is this "syntax" of which you speak? Is it witchcraft?

     Whilst "syntax" is a word that many programmers only encounter in the context of computers, it is in fact borrowed from wider linguistics. It refers to sentence structure: i.e. the rules of grammar; or, in other words, the rules that define what constitutes a valid sentence within the language.

     For example, the following English sentence contains a syntax error (because the indefinite article "a" must always precede a noun):

     This sentence contains syntax error a.

   • What does that have to do with MySQL?

     Whenever one issues a command to a computer, one of the very first things that it must do is "parse" that command in order to make sense of it. A "syntax error" means that the parser is unable to understand what is being asked because it does not constitute a valid command within the language: in other words, the command violates the grammar of the programming language.

     It's important to note that the computer must understand the command before it can do anything with it. Because there is a syntax error, MySQL has no idea what one is after and therefore gives up before it even looks at the database and therefore the schema or table contents are not relevant.

2. How do I fix it?

   Obviously, one needs to determine how it is that the command violates MySQL's grammar. This may sound pretty impenetrable, but MySQL is trying really hard to help us here. All we need to do is…

   • Read the message!

     MySQL not only tells us exactly where the parser encountered the syntax error, but also makes a suggestion for fixing it. For example, consider the following SQL command:

     UPDATE my_table WHERE id=101 SET name='foo'
     

     That command yields the following error message:

     ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE id=101 SET name='foo'' at line 1

     MySQL is telling us that everything seemed fine up to the word WHERE, but then a problem was encountered. In other words, it wasn't expecting to encounter WHERE at that point.

     Messages that say ...near '' at line... simply mean that the end of command was encountered unexpectedly: that is, something else should appear before the command ends.

   • Examine the actual text of your command!

     Programmers often create SQL commands using a programming language. For example a php program might have a (wrong) line like this:

     $result = $mysqli->query("UPDATE " . $tablename ."SET name='foo' WHERE id=101");
     

     If you write this this in two lines

     $query = "UPDATE " . $tablename ."SET name='foo' WHERE id=101"
     $result = $mysqli->query($query);
     

     then you can add echo $query; or var_dump($query) to see that the query actually says

     UPDATE userSET name='foo' WHERE id=101
     

     Often you'll see your error immediately and be able to fix it.

   • Obey orders!

     MySQL is also recommending that we "check the manual that corresponds to our MySQL version for the right syntax to use". Let's do that.

     I'm using MySQL v5.6, so I'll turn to that version's manual entry for an UPDATE command. The very first thing on the page is the command's grammar (this is true for every command):

     UPDATE [LOW_PRIORITY] [IGNORE] table_reference
         SET col_name1={expr1|DEFAULT} [, col_name2={expr2|DEFAULT}] ...
         [WHERE where_condition]
         [ORDER BY ...]
         [LIMIT row_count]
     

     The manual explains how to interpret this syntax under Typographical and Syntax Conventions, but for our purposes it's enough to recognise that: clauses contained within square brackets [ and ] are optional; vertical bars | indicate alternatives; and ellipses ... denote either an omission for brevity, or that the preceding clause may be repeated.

     We already know that the parser believed everything in our command was okay prior to the WHERE keyword, or in other words up to and including the table reference. Looking at the grammar, we see that table_reference must be followed by the SET keyword: whereas in our command it was actually followed by the WHERE keyword. This explains why the parser reports that a problem was encountered at that point.

   A note of reservation

   Of course, this was a simple example. However, by following the two steps outlined above (i.e. observing exactly where in the command the parser found the grammar to be violated and comparing against the manual's description of what was expected at that point), virtually every syntax error can be readily identified.

   I say "virtually all", because there's a small class of problems that aren't quite so easy to spot—and that is where the parser believes that the language element encountered means one thing whereas you intend it to mean another. Take the following example:

   UPDATE my_table SET where='foo'
   

   Again, the parser does not expect to encounter WHERE at this point and so will raise a similar syntax error—but you hadn't intended for that where to be an SQL keyword: you had intended for it to identify a column for updating! However, as documented under Schema Object Names:

   If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it. (Exception: A reserved word that follows a period in a qualified name must be an identifier, so it need not be quoted.) Reserved words are listed at Section 9.3, “Keywords and Reserved Words”.

   [ deletia ]

   The identifier quote character is the backtick (“`”):

   mysql> SELECT * FROM `select` WHERE `select`.id > 100;

   If the ANSI_QUOTES SQL mode is enabled, it is also permissible to quote identifiers within double quotation marks:

   mysql> CREATE TABLE "test" (col INT);
   ERROR 1064: You have an error in your SQL syntax...
   mysql> SET sql_mode='ANSI_QUOTES';
   mysql> CREATE TABLE "test" (col INT);
   Query OK, 0 rows affected (0.00 sec)

Like this:

var myString = "19 51 2.108997";
var stringParts = myString.split(" ");
var html = "<span>" + stringParts[0] + " " + stringParts[1] + "</span> <span>" + stringParts[2] + "</span";

The ISO C and C++ standards are bloody expensive. On the other hand, the INCITS republishes them for a lot less. http://www.techstreet.com/ seems to have the PDF for $30 (search for INCITS/ISO/IEC 14882:2003).

Hardcopy versions are available, too. Look for the British Standards Institute versions, published by Wiley.

You can get the diff for a stash with "git show stash@{0}" (or whatever the number of the stash is; see "git stash list"). It's easy to extract the section of the diff for a single file.

If you do not need to handle iframe content from a different domain, try this code, it will solve the problem completely and it's simple:

<script language="JavaScript">
<!--
function autoResize(id){
    var newheight;
    var newwidth;

    if(document.getElementById){
        newheight=document.getElementById(id).contentWindow.document .body.scrollHeight;
        newwidth=document.getElementById(id).contentWindow.document .body.scrollWidth;
    }

    document.getElementById(id).height= (newheight) + "px";
    document.getElementById(id).width= (newwidth) + "px";
}
//-->
</script>

<iframe src="usagelogs/default.aspx" width="100%" height="200px" id="iframe1" marginheight="0" frameborder="0" onLoad="autoResize('iframe1');"></iframe>

I'm not sure precisely what you're looking for, but this program:

    public class Building
    {
        public enum StatusType
        {
            open,
            closed,
            weird,
        };

        public string Name { get; set; }
        public StatusType Status { get; set; }
    }

    public static List <Building> buildingList = new List<Building> ()
    {
        new Building () { Name = "one", Status = Building.StatusType.open },
        new Building () { Name = "two", Status = Building.StatusType.closed },
        new Building () { Name = "three", Status = Building.StatusType.weird },

        new Building () { Name = "four", Status = Building.StatusType.open },
        new Building () { Name = "five", Status = Building.StatusType.closed },
        new Building () { Name = "six", Status = Building.StatusType.weird },
    };

    static void Main (string [] args)
    {
        var statusList = new List<Building.StatusType> () { Building.StatusType.open, Building.StatusType.closed };

        var q = from building in buildingList
                where statusList.Contains (building.Status)
                select building;

        foreach ( var b in q )
            Console.WriteLine ("{0}: {1}", b.Name, b.Status);
    }

produces the expected output:

one: open
two: closed
four: open
five: closed

This program compares a string representation of the enum and produces the same output:

    public class Building
    {
        public enum StatusType
        {
            open,
            closed,
            weird,
        };

        public string Name { get; set; }
        public string Status { get; set; }
    }

    public static List <Building> buildingList = new List<Building> ()
    {
        new Building () { Name = "one", Status = "open" },
        new Building () { Name = "two", Status = "closed" },
        new Building () { Name = "three", Status = "weird" },

        new Building () { Name = "four", Status = "open" },
        new Building () { Name = "five", Status = "closed" },
        new Building () { Name = "six", Status = "weird" },
    };

    static void Main (string [] args)
    {
        var statusList = new List<Building.StatusType> () { Building.StatusType.open, Building.StatusType.closed };
        var statusStringList = statusList.ConvertAll <string> (st => st.ToString ());

        var q = from building in buildingList
                where statusStringList.Contains (building.Status)
                select building;

        foreach ( var b in q )
            Console.WriteLine ("{0}: {1}", b.Name, b.Status);

        Console.ReadKey ();
    }

I created this extension method to convert one IEnumerable to another, but I'm not sure how efficient it is; it may just create a list behind the scenes.

public static IEnumerable <TResult> ConvertEach (IEnumerable <TSource> sources, Func <TSource,TResult> convert)
{
    foreach ( TSource source in sources )
        yield return convert (source);
}

Then you can change the where clause to:

where statusList.ConvertEach <string> (status => status.GetCharValue()).
    Contains (v.Status)

and skip creating the List<string> with ConvertAll () at the beginning.

Expression: "Total Count: " + (DT_WSTR, 5)@[User::Cnt]

to build on stu's answer. here's how i found the frame rate for a video from my mobile phone. i ran the following command for a while. i let the frame count get up to about ~ 10,000 before i got impatient and hit ^C:

$ ffmpeg -i 2013-07-07\ 12.00.59.mp4 -f null /dev/null 2>&1
...
Press [q] to stop, [?] for help
[null @ 0x7fcc80836000] Encoder did not produce proper pts, making some up.
frame= 7989 fps= 92 q=0.0 Lsize=N/A time=00:04:26.30 bitrate=N/A dup=10 drop=0    
video:749kB audio:49828kB subtitle:0 global headers:0kB muxing overhead -100.000042%
Received signal 2: terminating.
$

then, i grabbed two pieces of information from that line which starts with "frame=", the frame count, 7989, and the time, 00:04:26.30. You first need to convert the time into seconds and then divide the number of frames by seconds to get "frames per second". "frames per second" is your frame rate.

$ bc -l
0*60*60 + 4*60 + 26.3
266.3

7989/(4*60+26.3)
30.00000000000000000000
$

the framerate for my video is 30 fps.

You can write a function to return array of occurrence positions, Java has String.regionMatches function which is quite handy

public static ArrayList<Integer> occurrencesPos(String str, String substr) {
    final boolean ignoreCase = true;
    int substrLength = substr.length();
    int strLength = str.length();

    ArrayList<Integer> occurrenceArr = new ArrayList<Integer>();

    for(int i = 0; i < strLength - substrLength + 1; i++) {
        if(str.regionMatches(ignoreCase, i, substr, 0, substrLength))  {
            occurrenceArr.add(i);
        }
    }
    return occurrenceArr;
}

You can create simple float-based forms without having to lose your liquid layout. For example:

<style type="text/css">
    .row { clear: left; padding: 6px; }
    .row label { float: left; width: 10em; }
    .row .field { display: block; margin-left: 10em; }
    .row .field input, .row .field select {
        width: 100%;
        box-sizing: border-box;
        -moz-box-sizing: border-box; -webkit-box-sizing: border-box; -khtml-box-sizing: border-box;
    }
</style>

<div class="row">
    <label for="f-firstname">First name</label>
    <span class="field"><input name="firstname" id="f-firstname" value="Bob" /></span>
</div>
<div class="row">
    <label for="f-state">State</label>
    <span class="field"><select name="state" id="f-state">
        <option value="NY">NY</option>
    </select></span>
</div>

This does tend to break down, though, when you have complex form layouts where there's a grid of multiple fixed and flexible width columns. At that point you have to decide whether to stick with divs and abandon liquid layout in favour of just dropping everything into fixed pixel positions, or let tables do it.

For me personally, liquid layout is a more important usability feature than the exact elements used to lay out the form, so I usually go for tables.

You can use a 1 pixel per 1 pixel Java applet embedded in the page and use that for compression.

It's not JavaScript and the clients will need a Java runtime but it will do what you need.

One drawback of defaultdict over dict (dict.setdefault) is that a defaultdict object creates a new item EVERYTIME non existing key is given (eg with ==, print). Also the defaultdict class is generally way less common then the dict class, its more difficult to serialize it IME.

P.S. IMO functions|methods not meant to mutate an object, should not mutate an object.

it must be changed whenever anything changes that affects the serialization (additional fields, removed fields, change of field order, ...)

That's not correct, and you will be unable to cite an authoriitative source for that claim. It should be changed whenever you make a change that is incompatible under the rules given in the Versioning of Serializable Objects section of the Object Serialization Specification, which specifically does not include additional fields or change of field order, and when you haven't provided readObject(), writeObject(), and/or readResolve() or /writeReplace() methods and/or a serializableFields declaration that could cope with the change.

I changed the memory limit from .htaccess and this problem got resolved.

I was trying to scan my website from one of the antivirus plugin and there I was getting this problem. I increased memory by pasting this in my .htaccess file in Wordpress folder:

php_value memory_limit 512M

After scan was over, I removed this line to make the size as it was before.

THE EASIEST SOLUTION

It will add an extra in your options but your problem will be solved.

<?php 
    if ($editing == Yes) {
        echo "<option value=\".$MyValue.\" SELECTED>".$MyValue."</option>";
    }
?>

You may well want to use JSON-P instead (see below). First a quick explanation.

The header you've mentioned is from the Cross Origin Resource Sharing standard. Beware that it is not supported by some browsers people actually use, and on other browsers (Microsoft's, sigh) it requires using a special object (XDomainRequest) rather than the standard XMLHttpRequest that jQuery uses. It also requires that you change server-side resources to explicitly allow the other origin (www.xxxx.com).

To get the JSON data you're requesting, you basically have three options:

1. If possible, you can be maximally-compatible by correcting the location of the files you're loading so they have the same origin as the document you're loading them into. (I assume you must be loading them via Ajax, hence the Same Origin Policy issue showing up.)

2. Use JSON-P, which isn't subject to the SOP. jQuery has built-in support for it in its ajax call (just set dataType to "jsonp" and jQuery will do all the client-side work). This requires server side changes, but not very big ones; basically whatever you have that's generating the JSON response just looks for a query string parameter called "callback" and wraps the JSON in JavaScript code that would call that function. E.g., if your current JSON response is:

   {"weather": "Dreary start but soon brightening into a fine summer day."}
   

   Your script would look for the "callback" query string parameter (let's say that the parameter's value is "jsop123") and wraps that JSON in the syntax for a JavaScript function call:

   jsonp123({"weather": "Dreary start but soon brightening into a fine summer day."});
   

   That's it. JSON-P is very broadly compatible (because it works via JavaScript script tags). JSON-P is only for GET, though, not POST (again because it works via script tags).

3. Use CORS (the mechanism related to the header you quoted). Details in the specification linked above, but basically:

   A. The browser will send your server a "preflight" message using the OPTIONS HTTP verb (method). It will contain the various headers it would send with the GET or POST as well as the headers "Origin", "Access-Control-Request-Method" (e.g., GET or POST), and "Access-Control-Request-Headers" (the headers it wants to send).

   B. Your PHP decides, based on that information, whether the request is okay and if so responds with the "Access-Control-Allow-Origin", "Access-Control-Allow-Methods", and "Access-Control-Allow-Headers" headers with the values it will allow. You don't send any body (page) with that response.

   C. The browser will look at your response and see whether it's allowed to send you the actual GET or POST. If so, it will send that request, again with the "Origin" and various "Access-Control-Request-xyz" headers.

   D. Your PHP examines those headers again to make sure they're still okay, and if so responds to the request.

   In pseudo-code (I haven't done much PHP, so I'm not trying to do PHP syntax here):

   // Find out what the request is asking for
   corsOrigin = get_request_header("Origin")
   corsMethod = get_request_header("Access-Control-Request-Method")
   corsHeaders = get_request_header("Access-Control-Request-Headers")
   if corsOrigin is null or "null" {
       // Requests from a `file://` path seem to come through without an
       // origin or with "null" (literally) as the origin.
       // In my case, for testing, I wanted to allow those and so I output
       // "*", but you may want to go another way.
       corsOrigin = "*"
   }
   
   // Decide whether to accept that request with those headers
   // If so:
   
   // Respond with headers saying what's allowed (here we're just echoing what they
   // asked for, except we may be using "*" [all] instead of the actual origin for
   // the "Access-Control-Allow-Origin" one)
   set_response_header("Access-Control-Allow-Origin", corsOrigin)
   set_response_header("Access-Control-Allow-Methods", corsMethod)
   set_response_header("Access-Control-Allow-Headers", corsHeaders)
   if the HTTP request method is "OPTIONS" {
       // Done, no body in response to OPTIONS
       stop
   }
   // Process the GET or POST here; output the body of the response
   

   Again stressing that this is pseudo-code.

The way I have done this is by using my own class loader

URLClassLoader urlClassLoader = (URLClassLoader) ClassLoader.getSystemClassLoader();
DynamicURLClassLoader dynalLoader = new DynamicURLClassLoader(urlClassLoader);

And create the following class:

public class DynamicURLClassLoader extends URLClassLoader {

    public DynamicURLClassLoader(URLClassLoader classLoader) {
        super(classLoader.getURLs());
    }

    @Override
    public void addURL(URL url) {
        super.addURL(url);
    }
}

Works without any reflection

How about using "after" instead of "append".

$("#content ul li:last").after('<li><a href="/user/messages"><span class="tab">Message Center</span></a></li>');

".after()" can insert content, specified by the parameter, after each element in the set of matched elements.

Most of the times in such scenarios, you need to continue executing the script till the user keeps on entering "yes" and only need to stop when user enters "no". The below snippet would help you achieve this!

#!/bin/bash
input="yes"
while [ "$input" == "yes" ]
do
  echo "execute script functionality here..!!"
  echo "Do you want to continue (yes/no)?"
  read input
done

There are actually quite a number of ways to hide/show the toolbar while you are scrolling the content. One of the ways is to do it via the Android Design Support Library or more specifically the Coordinator layout aka. super-powered frame layout.

Basically all you need to do is to have the following structure in your layout file and you should be able to achieve the result that you want.

<CoordinatorLayout>
   <AppBarLayout>
   </AppBarLayout>
   <NestedScrollView>
   </NestedScrollView>
</CoordinatorLayout>

I have actually made a video to explain how it can be done in a step by step manner. Feel free to check it out and let me know if it helps. Thanks! :)

You can also compare with double value

BigDecimal a= new BigDecimal("1.1"); BigDecimal b =new BigDecimal("1.1");
System.out.println(a.doubleValue()==b.doubleValue());

            var xmlSerializer = new XmlSerializer(serialisableObject.GetType());

            using (var ms = new MemoryStream())
            {
                using (var xw = XmlWriter.Create(ms,

For parsing stdin from inside a script you need that trick with the FOR and FIND commands:

for /f "tokens=*" %%g in ('find /V ""') do (
     :: do what you want with %%g
     echo %%g
)

It could be something like that:

var a = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'];

var arrays = [], size = 3;
    
while (a.length > 0)
  arrays.push(a.splice(0, size));

console.log(arrays);

See splice Array's method.

In order to make

     http://localhost:8080

work, tomcat has to be started first. You can check server.xml file in conf folder for the port information. You can search if tomcat is installed on your machine. Just go to start and then type tomcat. If it is installed it will give you the directory where it is installed. Then you can select that path and run it from command prompt. Example if tomcat is installed in C:\Programfile\tomcat. You need to set this path in command prompt,go to bin folder and startup. Example: C:\Programfile\tomcat\bin\startup. Else you can also run it by directly going to the path and run startup batch file.

Instead of editing the bringup service, add a post-start delay to the service which it depends on. Edit cassandra.service like so:

ExecStartPost=/bin/sleep 30

This way the added sleep shouldn't slow down restarts of starting services that depend on it (though does slow down its own start, maybe that's desirable?).

Multiple commands can be put in parenthesis and spread over numerous lines; so something like echo hi && echo hello can be put like this:

( echo hi
  echo hello )

Also variables can help:

set AFILEPATH="C:\SOME\LONG\PATH\TO\A\FILE"
if exist %AFILEPATH% (
  start "" /b %AFILEPATH% -option C:\PATH\TO\SETTING...
) else (
...

Also I noticed with carets (^) that the if conditionals liked them to follow only if a space was present:

if exist ^

The scp operation is separate from your ssh login. You will need to issue an ssh command similar to the following one assuming jdoe is account with which you log into the remote system and that the remote system is example.com:

scp [email protected]:/somedir/table /home/me/Desktop/.

The scp command issued from the system where /home/me/Desktop resides is followed by the userid for the account on the remote server. You then add a ":" followed by the directory path and file name on the remote server, e.g., /somedir/table. Then add a space and the location to which you want to copy the file. If you want the file to have the same name on the client system, you can indicate that with a period, i.e. "." at the end of the directory path; if you want a different name you could use /home/me/Desktop/newname, instead. If you were using a nonstandard port for SSH connections, you would need to specify that port with a "-P n" (capital P), where "n" is the port number. The standard port is 22 and if you aren't specifying it for the SSH connection then you won't need that.

SET SESSION group_concat_max_len = 1000000;

is a temporary, session-scope, setting. It only applies to the current session You should use it like this.

SET SESSION group_concat_max_len = 1000000;
select group_concat(column) from table group by column

You can do this even in sharing hosting, but when you use an other session, you need to repeat the SET SESSION command.

The typical usage of shifting a variable and assigning back to the variable can be rewritten with shorthand operators <<=, >>=, or >>>=, also known in the spec as Compound Assignment Operators.

For example,

i >>= 2

produces the same result as

i = i >> 2

Here is working version:

var newVal = 10;
var slider = $('#slider');        
var s = $(slider);
$(slider).val(newVal);
$(slider).slider('refresh');

We can also use DOMNodeRemoved:

$("#youridwhichremoved").on("DOMNodeRemoved", function () {
// do stuff
})

you could do something like (below)

var query = from p in context.T1

        join q in context.T2

        on

        new { p.Col1, p.Col2 }

        equals

         new { q.Col1, q.Col2 }

        select new {p...., q......};

In your code you are missing Class.forName("com.mysql.jdbc.Driver");

This is what you are missing to have everything working.

Use repr:

a = "Hello\tWorld\nHello World"
print(repr(a))
# 'Hello\tWorld\nHello World'

Note you do not get \s for a space. I hope that was a typo...?

But if you really do want \s for spaces, you could do this:

print(repr(a).replace(' ',r'\s'))

You can pass in the data to be used in the mouseover like this- the mouseover event uses a function with your previously entered data as an argument (and the index as a second argument) so you don't need to use enter() a second time.

vis.selectAll("circle")
.data(datafiltered).enter().append("svg:circle")
.attr("cx", function(d) { return x(d.x);})
.attr("cy", function(d) {return y(d.y)})
.attr("fill", "red").attr("r", 15)
.on("mouseover", function(d,i) {
    d3.select(this).append("text")
        .text( d.x)
        .attr("x", x(d.x))
        .attr("y", y(d.y)); 
});

In my case I also have unmanaged dll's (C++) in workspace and if you specify:

<files>
    <file src="bin\*.dll" target="lib" />
</files>

nuget would try to load every dll as an assembly, even the C++ libraries! To avoid this behaviour explicitly define your C# assemblies with references tag:

<references>
    <reference file="Managed1.dll" />
    <reference file="Managed2.dll" />
</references>

Remark: parent of references is metadata -> according to documentation https://docs.microsoft.com/en-us/nuget/reference/nuspec#general-form-and-schema

Documentation: https://docs.microsoft.com/en-us/nuget/reference/nuspec

new WindowSettings();

You just closed a brand new instance of the form that wasn't visible in the first place.

You need to close the original instance of the form by accepting it as a constructor parameter and storing it in a field.

Try to replace this:

myLongList.ItemsSource = writings;

with this

Dispatcher.BeginInvoke(() => myLongList.ItemsSource = writings);

There is additionally collections’ stream() util with Java 8

collection.forEach((temp) -> {
            System.out.println(temp);
});

or

collection.forEach(System.out::println);

More information about Java 8 stream and collections for wonderers link

In this line:

const char* cstr2 = ss.str().c_str();

ss.str() will make a copy of the contents of the stringstream. When you call c_str() on the same line, you'll be referencing legitimate data, but after that line the string will be destroyed, leaving your char* to point to unowned memory.

How to simple shade color in PHP?

<?php
function shadeColor ($color='#cccccc', $percent=-25) {

  $color = Str_Replace("#",Null,$color);

  $r = Hexdec(Substr($color,0,2));
  $g = Hexdec(Substr($color,2,2));
  $b = Hexdec(Substr($color,4,2));

  $r = (Int)($r*(100+$percent)/100);
  $g = (Int)($g*(100+$percent)/100);
  $b = (Int)($b*(100+$percent)/100);

  $r = Trim(Dechex(($r<255)?$r:255));  
  $g = Trim(Dechex(($g<255)?$g:255));  
  $b = Trim(Dechex(($b<255)?$b:255));

  $r = ((Strlen($r)==1)?"0{$r}":$r);
  $g = ((Strlen($g)==1)?"0{$g}":$g);
  $b = ((Strlen($b)==1)?"0{$b}":$b);

  return (String)("#{$r}{$g}{$b}");
}

echo shadeColor(); // #999999

As described by the link I've given in comment, this

$('p[MyTag]').each(function(index) {
  document.write(index + ': ' + $(this).text() + "<br>");});

works (playable example).

Call back vs Callback Function

A Callback is a function that is to be executed after another function has finished executing — hence the name ‘call back’.

What is a Callback Function?

• In JavaScript, functions are objects. Because of this, functions can take functions as arguments, and can be returned by other functions. Functions that do this are called higher-order functions. Any function that is passed as an argument is called a callback function.
• a callback function is a function that is passed to another function (let's call this other function otherFunction) as a parameter, and the callback function is called (or executed) inside the otherFunction.

    function action(x, y, callback) {
        return callback(x, y);
    }
    
    function multiplication(x, y) {
        return x * y;
    }
    
    function addition(x, y) {
        return x + y;
    }

    alert(action(10, 10, multiplication)); // output: 100

    alert(action(10, 10, addition)); // output: 20

In SOA, callback allows the Plugin Modules to access services from the container/environment.

I've fixed it by downgrading to lower version sudo apt-get install yarn=1.12.3-1

Since I have to store various types of content in my blob field/column, I am suppose to update my code like this:

echo "data: $mime" $result['$data']";

where: mime can be an image of any kind, text, word document, text document, PDF document, etc... content datatype is blob in database.

Approach 1

While converting a gray scale image to a binary image, we usually use cv2.threshold() and set a threshold value manually. Sometimes to get a decent result we opt for Otsu's binarization.

I have a small hack I came across while reading some blog posts.

1. Convert your color (RGB) image to gray scale.
2. Obtain the median of the gray scale image.
3. Choose a threshold value either 33% above the median

Why 33%?

This is because 33% works for most of the images/data-set.

You can also work out the same approach by replacing median with the mean.

Approach 2

Another approach would be to take an x number of standard deviations (std) from the mean, either on the positive or negative side; and set a threshold. So it could be one of the following:

• th1 = mean - (x * std)
• th2 = mean + (x * std)

Note: Before applying threshold it is advisable to enhance the contrast of the gray scale image locally (See CLAHE).

According to the documentation.

If you are running on the TensorFlow or CNTK backends, your code will automatically run on GPU if any available GPU is detected.

You can check what all devices are used by tensorflow by -

from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())

Also as suggested in this answer

import tensorflow as tf
sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))

This will print whether your tensorflow is using a CPU or a GPU backend. If you are running this command in jupyter notebook, check out the console from where you have launched the notebook.

If you are sceptic whether you have installed the tensorflow gpu version or not. You can install the gpu version via pip.

pip install tensorflow-gpu

you can use your method by this way

var app = 'AirFare';
var d1 = new Date();
var d2 = new Date();

$http({
    url: '/api/apiControllerName/methodName',
    method: 'POST',
    params: {application:app, from:d1, to:d2},
    headers: { 'Content-Type': 'application/json;charset=utf-8' },
    //timeout: 1,
    //cache: false,
    //transformRequest: false,
    //transformResponse: false
}).then(function (results) {
    return results;
}).catch(function (e) {

});

This problem is because you have used an old adb version and not support on your device. or you have more than one adb

The key is:

• make sure you have a latest adb executable on your SDK
• Make sure to run adb command from "SDK_DIR/platform-tools/" because this should be the latest version (type command "which adb" to check) if u have more than one adb file, you can rename another one.

in my case, on my Windows 7 i have one more adb on "C:\Windows\adb.exe" and its an old version, so my adb command always run from that file. I fixed the problem by running adb form my sdk directory "SDK_DIR/platform-tools/adb.exe"

Under Linux, got same problem after Android Studio update (and several months without using it...).

I solved it by running the following command in a console:

mv .subversion/ .subversion.bak

I prefer that command to rm -R .subversion since it left me a rollback option.

Could be short as:

LocalDate.now().format(DateTimeFormatter.ofPattern("dd/MM/yyyy"));

As long as the macros in question are in the same workbook and you verify the names exist, you can call those macros from any other module by name, not by module.

So if in Module1 you had two macros Macro1 and Macro2 and in Module2 you had Macro3 and Macro 4, then in another macro you could call them all:

Sub MasterMacro()
    Call Macro1
    Call Macro2
    Call Macro3
    Call Macro4
End Sub

SP is the stack register a shortcut for typing r13. LR is the link register a shortcut for r14. And PC is the program counter a shortcut for typing r15.

When you perform a call, called a branch link instruction, bl, the return address is placed in r14, the link register. the program counter pc is changed to the address you are branching to.

There are a few stack pointers in the traditional ARM cores (the cortex-m series being an exception) when you hit an interrupt for example you are using a different stack than when running in the foreground, you dont have to change your code just use sp or r13 as normal the hardware has done the switch for you and uses the correct one when it decodes the instructions.

The traditional ARM instruction set (not thumb) gives you the freedom to use the stack in a grows up from lower addresses to higher addresses or grows down from high address to low addresses. the compilers and most folks set the stack pointer high and have it grow down from high addresses to lower addresses. For example maybe you have ram from 0x20000000 to 0x20008000 you set your linker script to build your program to run/use 0x20000000 and set your stack pointer to 0x20008000 in your startup code, at least the system/user stack pointer, you have to divide up the memory for other stacks if you need/use them.

Stack is just memory. Processors normally have special memory read/write instructions that are PC based and some that are stack based. The stack ones at a minimum are usually named push and pop but dont have to be (as with the traditional arm instructions).

If you go to http://github.com/lsasim I created a teaching processor and have an assembly language tutorial. Somewhere in there I go through a discussion about stacks. It is NOT an arm processor but the story is the same it should translate directly to what you are trying to understand on the arm or most other processors.

Say for example you have 20 variables you need in your program but only 16 registers minus at least three of them (sp, lr, pc) that are special purpose. You are going to have to keep some of your variables in ram. Lets say that r5 holds a variable that you use often enough that you dont want to keep it in ram, but there is one section of code where you really need another register to do something and r5 is not being used, you can save r5 on the stack with minimal effort while you reuse r5 for something else, then later, easily, restore it.

Traditional (well not all the way back to the beginning) arm syntax:

...
stmdb r13!,{r5}
...temporarily use r5 for something else...
ldmia r13!,{r5}
...

stm is store multiple you can save more than one register at a time, up to all of them in one instruction.

db means decrement before, this is a downward moving stack from high addresses to lower addresses.

You can use r13 or sp here to indicate the stack pointer. This particular instruction is not limited to stack operations, can be used for other things.

The ! means update the r13 register with the new address after it completes, here again stm can be used for non-stack operations so you might not want to change the base address register, leave the ! off in that case.

Then in the brackets { } list the registers you want to save, comma separated.

ldmia is the reverse, ldm means load multiple. ia means increment after and the rest is the same as stm

So if your stack pointer were at 0x20008000 when you hit the stmdb instruction seeing as there is one 32 bit register in the list it will decrement before it uses it the value in r13 so 0x20007FFC then it writes r5 to 0x20007FFC in memory and saves the value 0x20007FFC in r13. Later, assuming you have no bugs when you get to the ldmia instruction r13 has 0x20007FFC in it there is a single register in the list r5. So it reads memory at 0x20007FFC puts that value in r5, ia means increment after so 0x20007FFC increments one register size to 0x20008000 and the ! means write that number to r13 to complete the instruction.

Why would you use the stack instead of just a fixed memory location? Well the beauty of the above is that r13 can be anywhere it could be 0x20007654 when you run that code or 0x20002000 or whatever and the code still functions, even better if you use that code in a loop or with recursion it works and for each level of recursion you go you save a new copy of r5, you might have 30 saved copies depending on where you are in that loop. and as it unrolls it puts all the copies back as desired. with a single fixed memory location that doesnt work. This translates directly to C code as an example:

void myfun ( void )
{
   int somedata;
}

In a C program like that the variable somedata lives on the stack, if you called myfun recursively you would have multiple copies of the value for somedata depending on how deep in the recursion. Also since that variable is only used within the function and is not needed elsewhere then you perhaps dont want to burn an amount of system memory for that variable for the life of the program you only want those bytes when in that function and free that memory when not in that function. that is what a stack is used for.

A global variable would not be found on the stack.

Going back...

Say you wanted to implement and call that function you would have some code/function you are in when you call the myfun function. The myfun function wants to use r5 and r6 when it is operating on something but it doesnt want to trash whatever someone called it was using r5 and r6 for so for the duration of myfun() you would want to save those registers on the stack. Likewise if you look into the branch link instruction (bl) and the link register lr (r14) there is only one link register, if you call a function from a function you will need to save the link register on each call otherwise you cant return.

...
bl myfun
    <--- the return from my fun returns here
...


myfun:
stmdb sp!,{r5,r6,lr}
sub sp,#4 <--- make room for the somedata variable
...
some code here that uses r5 and r6
bl more_fun <-- this modifies lr, if we didnt save lr we wouldnt be able to return from myfun
   <---- more_fun() returns here
...
add sp,#4 <-- take back the stack memory we allocated for the somedata variable
ldmia sp!,{r5,r6,lr}
mov pc,lr <---- return to whomever called myfun.

So hopefully you can see both the stack usage and link register. Other processors do the same kinds of things in a different way. for example some will put the return value on the stack and when you execute the return function it knows where to return to by pulling a value off of the stack. Compilers C/C++, etc will normally have a "calling convention" or application interface (ABI and EABI are names for the ones ARM has defined). if every function follows the calling convention, puts parameters it is passing to functions being called in the right registers or on the stack per the convention. And each function follows the rules as to what registers it does not have to preserve the contents of and what registers it has to preserve the contents of then you can have functions call functions call functions and do recursion and all kinds of things, so long as the stack does not go so deep that it runs into the memory used for globals and the heap and such, you can call functions and return from them all day long. The above implementation of myfun is very similar to what you would see a compiler produce.

ARM has many cores now and a few instruction sets the cortex-m series works a little differently as far as not having a bunch of modes and different stack pointers. And when executing thumb instructions in thumb mode you use the push and pop instructions which do not give you the freedom to use any register like stm it only uses r13 (sp) and you cannot save all the registers only a specific subset of them. the popular arm assemblers allow you to use

push {r5,r6}
...
pop {r5,r6}

in arm code as well as thumb code. For the arm code it encodes the proper stmdb and ldmia. (in thumb mode you also dont have the choice as to when and where you use db, decrement before, and ia, increment after).

No you absolutly do not have to use the same registers and you dont have to pair up the same number of registers.

push {r5,r6,r7}
...
pop {r2,r3}
...
pop {r1}

assuming there is no other stack pointer modifications in between those instructions if you remember the sp is going to be decremented 12 bytes for the push lets say from 0x1000 to 0x0FF4, r5 will be written to 0xFF4, r6 to 0xFF8 and r7 to 0xFFC the stack pointer will change to 0x0FF4. the first pop will take the value at 0x0FF4 and put that in r2 then the value at 0x0FF8 and put that in r3 the stack pointer gets the value 0x0FFC. later the last pop, the sp is 0x0FFC that is read and the value placed in r1, the stack pointer then gets the value 0x1000, where it started.

The ARM ARM, ARM Architectural Reference Manual (infocenter.arm.com, reference manuals, find the one for ARMv5 and download it, this is the traditional ARM ARM with ARM and thumb instructions) contains pseudo code for the ldm and stm ARM istructions for the complete picture as to how these are used. Likewise well the whole book is about the arm and how to program it. Up front the programmers model chapter walks you through all of the registers in all of the modes, etc.

If you are programming an ARM processor you should start by determining (the chip vendor should tell you, ARM does not make chips it makes cores that chip vendors put in their chips) exactly which core you have. Then go to the arm website and find the ARM ARM for that family and find the TRM (technical reference manual) for the specific core including revision if the vendor has supplied that (r2p0 means revision 2.0 (two point zero, 2p0)), even if there is a newer rev, use the manual that goes with the one the vendor used in their design. Not every core supports every instruction or mode the TRM tells you the modes and instructions supported the ARM ARM throws a blanket over the features for the whole family of processors that that core lives in. Note that the ARM7TDMI is an ARMv4 NOT an ARMv7 likewise the ARM9 is not an ARMv9. ARMvNUMBER is the family name ARM7, ARM11 without a v is the core name. The newer cores have names like Cortex and mpcore instead of the ARMNUMBER thing, which reduces confusion. Of course they had to add the confusion back by making an ARMv7-m (cortex-MNUMBER) and the ARMv7-a (Cortex-ANUMBER) which are very different families, one is for heavy loads, desktops, laptops, etc the other is for microcontrollers, clocks and blinking lights on a coffee maker and things like that. google beagleboard (Cortex-A) and the stm32 value line discovery board (Cortex-M) to get a feel for the differences. Or even the open-rd.org board which uses multiple cores at more than a gigahertz or the newer tegra 2 from nvidia, same deal super scaler, muti core, multi gigahertz. A cortex-m barely brakes the 100MHz barrier and has memory measured in kbytes although it probably runs of a battery for months if you wanted it to where a cortex-a not so much.

sorry for the very long post, hope it is useful.

Please find the code in jsFiddle. It uses jQuery to modify the href of the link. You can use any other library in its place. It should work.

HTML

<a id="emailLnk" href="#">
    <img src="http://ssl.gstatic.com/gb/images/j_e6a6aca6.png">
</a>

JS

$(document).ready(function() {
    $("#emailLnk").attr('href',"mailto:[email protected]");
});?

UPDATE

Another code sample, if the id is known only during the click event

$(document).ready(function() {
    $("#emailLnk").click(function()
     {
         window.location.href = "mailto:[email protected]";
     });

In my case Microsoft.Common.CurrentVersion.targets was corrupted. I copied this file from other system and it worked.

You can create an extension method for HtmlHelper to simplify the code in your CSHTML file. You could replace your tags with a method like this:

// Sample usage in CSHTML
@Html.ActionImage("Edit", new { id = MyId }, "~/Content/Images/Image.bmp", "Edit")

Here is a sample extension method for the code above:

// Extension method
public static MvcHtmlString ActionImage(this HtmlHelper html, string action, object routeValues, string imagePath, string alt)
{
    var url = new UrlHelper(html.ViewContext.RequestContext);

    // build the <img> tag
    var imgBuilder = new TagBuilder("img");
    imgBuilder.MergeAttribute("src", url.Content(imagePath));
    imgBuilder.MergeAttribute("alt", alt);
    string imgHtml = imgBuilder.ToString(TagRenderMode.SelfClosing);

    // build the <a> tag
    var anchorBuilder = new TagBuilder("a");
    anchorBuilder.MergeAttribute("href", url.Action(action, routeValues));
    anchorBuilder.InnerHtml = imgHtml; // include the <img> tag inside
    string anchorHtml = anchorBuilder.ToString(TagRenderMode.Normal);

    return MvcHtmlString.Create(anchorHtml);
}

To check if a grammar is LL(1), one option is to construct the LL(1) parsing table and check for any conflicts. These conflicts can be

• FIRST/FIRST conflicts, where two different productions would have to be predicted for a nonterminal/terminal pair.
• FIRST/FOLLOW conflicts, where two different productions are predicted, one representing that some production should be taken and expands out to a nonzero number of symbols, and one representing that a production should be used indicating that some nonterminal should be ultimately expanded out to the empty string.
• FOLLOW/FOLLOW conflicts, where two productions indicating that a nonterminal should ultimately be expanded to the empty string conflict with one another.

Let's try this on your grammar by building the FIRST and FOLLOW sets for each of the nonterminals. Here, we get that

FIRST(X) = {a, b, z}
FIRST(Y) = {b, epsilon}
FIRST(Z) = {epsilon} 

We also have that the FOLLOW sets are

FOLLOW(X) = {$}
FOLLOW(Y) = {z}
FOLLOW(Z) = {z}

From this, we can build the following LL(1) parsing table:

    a    b    z   $
X   a    Yz   Yz  
Y        bZ   eps
Z             eps

Since we can build this parsing table with no conflicts, the grammar is LL(1).

To check if a grammar is LR(0) or SLR(1), we begin by building up all of the LR(0) configurating sets for the grammar. In this case, assuming that X is your start symbol, we get the following:

(1)
X' -> .X
X -> .Yz
X -> .a
Y -> .
Y -> .bZ

(2)
X' -> X.

(3)
X -> Y.z

(4)
X -> Yz.

(5)
X -> a.

(6)
Y -> b.Z
Z -> .

(7)
Y -> bZ.

From this, we can see that the grammar is not LR(0) because there are shift/reduce conflicts in states (1) and (6). Specifically, because we have the reduce items Z → . and Y → ., we can't tell whether to reduce the empty string to these symbols or to shift some other symbol. More generally, no grammar with ε-productions is LR(0).

However, this grammar might be SLR(1). To see this, we augment each reduction with the lookahead set for the particular nonterminals. This gives back this set of SLR(1) configurating sets:

(1)
X' -> .X
X -> .Yz [$]
X -> .a  [$]
Y -> .   [z]
Y -> .bZ [z]

(2)
X' -> X.

(3)
X -> Y.z [$]

(4)
X -> Yz. [$]

(5)
X -> a.  [$]

(6)
Y -> b.Z [z]
Z -> .   [z]

(7)
Y -> bZ. [z]

Now, we don't have any more shift-reduce conflicts. The conflict in state (1) has been eliminated because we only reduce when the lookahead is z, which doesn't conflict with any of the other items. Similarly, the conflict in (6) is gone for the same reason.

Hope this helps!

As per my understanding, this can be done in two ways :

1) You can use Directory Class with Getfiles method and traverse across all files to check our required extension.

Directory.GetFiles("your_folder_path)[i].Contains("*.txt")

2) You can use Path Class with GetExtension Method which takes file path as a parameter and verifies the extension.To get the file path, just have a looping condition that will fetch a single file and return the filepath that can be used for verification.

Path.GetExtension(your_file_path).Equals(".json")

Note : Both the logic has to be inside a looping condition.

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.

Try this:

urllib.pathname2url(stringToURLEncode)

urlencode won't work because it only works on dictionaries. quote_plus didn't produce the correct output.

res is an HttpResponse object which extends from OutgoingMessage. res.send calls res.end which is implemented by OutgoingMessage to send HTTP response and close connection. We see code here

It is easy to assign repeated values to an array:

x(1:10) = 5;

If you want to generate the array of elements inline in a statement try something like this:

ones(1,10) * 5

or with repmat

repmat(5, 1, 10)

If the place you're gonna paste have no problem with pasting a table formating (like the browser URL bar), I think the easiest way is this:

Sheets(1).Range("A1000").Value = string
Sheets(1).Range("A1000").Copy
MsgBox "Paste before closing this dialog."
Sheets(1).Range("A1000").Value = ""

You can create a thread just like this:

 Thread thread = new Thread(new Runnable() {
                    public void run() {

                       }
                    });
                thread.start();

Also, you can use Runnable, Asyntask, Timer, TimerTaks and AlarmManager to excecute Threads.

    if $("form")[0].checkValidity()
      $.ajax(

        }
        dataType: "json"
        success: (data) ->

      )
    else
      #important
      $("form")[0].reportValidity()

It's even easier if you consider that the Generic List in C# is indexed from 0 like an array. This means you can just use something like:

int index = 0; int i = accounts[index];

I'm not entirely sure of the general purpose of the function, but you could always do this:

function getMachine(color, qty) {
    var retval;
    $("#getMachine li").each(function() {
        var thisArray = $(this).text().split("~");
        if(thisArray[0] == color&& qty>= parseInt(thisArray[1]) && qty<= parseInt(thisArray[2])) {
            retval = thisArray[3];
            return false;
        }
    });
    return retval;
}

var retval = getMachine(color, qty);

I needed an example using React.Component so I am posting it:

import React from 'react';
import * as Redux from 'react-redux';

class NavigationHeader extends React.Component {

}

const mapStateToProps = function (store) {
    console.log(`mapStateToProps ${store}`);
    return {
        navigation: store.navigation
    };
};

export default Redux.connect(mapStateToProps)(NavigationHeader);

i know this is an old post but hopefully this will help someone.

In the 1990’s different versions of js started coming out like javascript from netscape, Js script from Microsoft. So ecmascript was introduced as a standard. But ecmascript forms only a part of javascript which specifies its core syntax,types,objects etc. Probably that explains the inconsistent implementations of javascript across diff. browsers

Reference - Wrox(Professional Javascript For Web Developers)

I'm a java developer that happened to get on a team without a DBA and one where as a developer, I can't get DBA rights. I was tasked with moving an entire schema between two databases, so without having a DBA, I had to do it and do it by running scripts, not being able to use the GUI in SQL Server 2008 because I didn't have admin privileges.

Everything was moved without issue, however, when running a stored procedure on the new schema.table, I found I lost the identity field in a table. I double checked the script that created the table and it was there, however, SQL Server didn't get it when I ran the script. I was told later by a DBA that he had seen this same problem before.

In any event, for SQL Server 2008, these are the steps I took to get this resolved and they worked, so I'm posting this here in the hopes it will be a help to someone. This is what I did as I had FK dependencies on another table that made this more difficult:

I used this query to verify the identity was indeed missing and to view dependencies on the table.

1.) Find statistics on a table:

exec sp_help 'dbo.table_name_old';

2.) Create a duplicate, identical new table, except add an identity field on the PK field where it had been before.

3.) Disable the identity to move data.

SET IDENTITY_INSERT dbo.table_name ON 

4.) Transfer the data.

INSERT INTO dbo.table_name_new
(
field1, field2, etc...
)
SELECT 
field1, field2, etc...
FROM 
dbo.table_name_old;

5.) Verify the data is there.

SELECT * FROM dbo.table_name_new

6.) Re-enable the identity.

SET IDENTITY_INSERT ToyRecP.ToyAwards.lkpFile_New OFF

7.) This is the best script I found to get all the FK relationships to verify which table(s) the original table references as dependencies and I came across many, so it is a keeper!

SELECT f.name AS ForeignKey,
   OBJECT_NAME(f.parent_object_id) AS TableName,
   COL_NAME(fc.parent_object_id, fc.parent_column_id) AS ColumnName,
   OBJECT_NAME (f.referenced_object_id) AS ReferenceTableName,
   COL_NAME(fc.referenced_object_id, fc.referenced_column_id) AS ReferenceColumnName
FROM sys.foreign_keys AS f
INNER JOIN sys.foreign_key_columns AS fc
   ON f.OBJECT_ID = fc.constraint_object_id
   ORDER BY ReferenceTableName;

8.) Make sure you have all the PK and FK scripts for all the tables involved, before this next step.

9.) You can right-click on each key and script this using SQL Server 2008

10.) Drop the FK(s) from the dependency table(s) using this syntax:

ALTER TABLE [dbo].[table_name] DROP CONSTRAINT [Name_of_FK]

11.) Drop the original table:

DROP TABLE dbo.table_name_old;

13.) These next steps rely on the scripts you created in SQL Server 2008 in step 9.

--Add the PK to the new table.

--Add the FK to the new table.

--Add the FK's back to the dependency table.

14.) Verify everything is correct and complete. I used the GUI to look at the tables.

15.) Rename the new table to the original tables name.

exec sp_RENAME '[Schema_Name.OldTableName]' , '[NewTableName]';

Finally, everything worked!

String courseID = "Comp-101";
List<String> scores = new ArrayList<String> ();
scores.add("100");
scores.add("90");
scores.add("80");
scores.add("97");

Map<String, ArrayList<String>> myMap = new HashMap<String, ArrayList<String>>();
myMap.put(courseID, scores);

Hope this helps!

from subprocess import call

It works for me. Basically, it executes shell command cp.

You can just pass a list of the two points you want to connect to plt.plot. To make this easily expandable to as many points as you want, you could define a function like so.

import matplotlib.pyplot as plt

x=[-1 ,0.5 ,1,-0.5]
y=[ 0.5,  1, -0.5, -1]

plt.plot(x,y, 'ro')

def connectpoints(x,y,p1,p2):
    x1, x2 = x[p1], x[p2]
    y1, y2 = y[p1], y[p2]
    plt.plot([x1,x2],[y1,y2],'k-')

connectpoints(x,y,0,1)
connectpoints(x,y,2,3)

plt.axis('equal')
plt.show()

Note, that function is a general function that can connect any two points in your list together.

To expand this to 2N points, assuming you always connect point i to point i+1, we can just put it in a for loop:

import numpy as np
for i in np.arange(0,len(x),2):
    connectpoints(x,y,i,i+1)

In that case of always connecting point i to point i+1, you could simply do:

for i in np.arange(0,len(x),2):
    plt.plot(x[i:i+2],y[i:i+2],'k-')

I found that these instructions were not enough. I also had to search through the code files for models, controllers, and views as well as the AppStart files to change the namespace.

Since I was copying my project not just renaming it, I also had to go into the applicationhost.config for IIS express and recreate the bindings using different port numbers and change the physical directory as well.

By definition "A Set is a collection of values, where each value may occur only once." So, if your array has repeated values then only one value among the repeated values will be added to your Set.

var arr = [1, 2, 3];
var set = new Set(arr);
console.log(set); // {1,2,3}


var arr = [1, 2, 1];
var set = new Set(arr);
console.log(set); // {1,2}

So, do not convert to set if you have repeated values in your array.

Following steps solves my problem: Add "C:\Windows\System32\" to your system path variables Run npm eject, Run npm start, Run npm eject, and agian run npm start And it worked
