File currentDirectory = new File(new File(".").getAbsolutePath());
System.out.println(currentDirectory.getCanonicalPath());
System.out.println(currentDirectory.getAbsolutePath());

Prints something like:

/path/to/current/directory
/path/to/current/directory/.

Note that File.getCanonicalPath() throws a checked IOException but it will remove things like ../../../

I was going to add this just to be silly, but also because it shows newcomers the potential usefulness of aliasing functions and/or imports.

Having written it, I think this code is more readable (i.e. lower time to grasp intention) than the other answers to date, and readability is (usually) king.

from os.path import dirname as up

two_up = up(up(__file__))

Note: you only want to do this kind of thing if your module is very small, or contextually cohesive.

string foo = "D:\\Projects\\Some\\Kind\\Of\\Pathproblem\\wuhoo.xml";

This will work, or the previous examples will, too. @"..." means treat everything between the quote marks literally, so you can do

@"Hello
world"

To include a literal newline. I'm more old school and prefer to escape "\" with "\\"

Assuming you want to add this path for all users on the system, add the following line to your /etc/profile.d/play.sh (and possibly play.csh, etc):

PATH=$PATH:/home/me/play
export PATH

I had a similar issue, but the reason that %ANT_HOME% wasn't resolving is that I had added it as a USER variable, not a SYSTEM one. Sorted now, thanks to this post.

If you go to your android-sdk/tools folder I think you'll find a message :

The adb tool has moved to platform-tools/

If you don't see this directory in your SDK, launch the SDK and AVD Manager (execute the android tool) and install "Android SDK Platform-tools"

Please also update your PATH environment variable to include the platform-tools/ directory, so you can execute adb from any location.

So you should also add C:/android-sdk/platform-tools to you environment path. Also after you modify the PATH variable make sure that you start a new CommandPrompt window.

I faced the same issue when I uninstalled and reinstalled a different version of 2.7.x of Python on my system using a 32 bit Windows Installer. I got the same error on most of my import statements. I uninstalled the newly installed Python and downloaded a 64 bit Windows installer and reinstalled Python again and it worked. Hope this helps you.

git rev-parse --show-toplevel

could be enough if executed within a git repo.
From git rev-parse man page:

--show-toplevel

Show the absolute path of the top-level directory.

For older versions (before 1.7.x), the other options are listed in "Is there a way to get the git root directory in one command?":

git rev-parse --git-dir

That would give the path of the .git directory.

The OP mentions:

git rev-parse --show-prefix

which returns the local path under the git repo root. (empty if you are at the git repo root)

Note: for simply checking if one is in a git repo, I find the following command quite expressive:

git rev-parse --is-inside-work-tree

And yes, if you need to check if you are in a .git git-dir folder:

git rev-parse --is-inside-git-dir

In Macbook, step by step:

1. First of all open terminal and write it: cd ~/
2. Create your bash file: touch .bash_profile

You created your ".bash_profile" file but if you would like to edit it, you should write it;

3. Edit your bash profile: open -e .bash_profile

After you can save from top-left corner of screen: File > Save

@canerkaseler

If you want to keep the path to the file and just remove the extension

>>> file = '/root/dir/sub.exten/file.data.1.2.dat'
>>> print ('.').join(file.split('.')[:-1])
/root/dir/sub.exten/file.data.1.2

File currDir = new File(".");
String path = currDir.getAbsolutePath();
System.out.println(path);

This will print . at the end. To remove, simply truncate the string by one char e.g.:

File currDir = new File(".");
String path = currDir.getAbsolutePath();
path = path.substring(0, path.length()-1);
System.out.println(path);

Depending on your needs, you can probably rely on node's path module.

You may not be able to hit the filesystem (e.g. the file hasn't been created yet) and tbh you probably want to avoid hitting the filesystem unless you really need the extra validation. If you can make the assumption that what you are checking for follows .<extname> format, just look at the name.

Obviously if you are looking for a file without an extname you will need to hit the filesystem to be sure. But keep it simple until you need more complicated.

const path = require('path');

function isFile(pathItem) {
  return !!path.extname(pathItem);
}

You can see a complete example using java 8, recursion and streams -> Dijkstra algorithm with java

In NodeJS, __filename.split(/\|//).pop() returns just the file name from the absolute file path on any OS platform. Why need to care about remembering/importing an API while this regex approach also letting us recollect our regex skills.

You can make windows bat file like this.

D: (your dexired drive)
cd \Your\Desired\Start\Derectory
Jupyter notebook

Save it as 'JupyterNB.bat' (or whatever you like), and double click it.

Don't use spaces...

(Incorrect)

SPTH = '/home/Foo/Documents/Programs/ShellScripts/Butler'

(Correct)

SPTH='/home/Foo/Documents/Programs/ShellScripts/Butler'

Clean solution while staying with the nio API:

Files.isDirectory(path)
Files.isRegularFile(path)

You can manage to obtain value of a deep object member with dot notation without any external JavaScript library with the simple following trick:

new Function('_', 'return _.' + path)(obj);

In your case to obtain value of part1.name from someObject just do:

new Function('_', 'return _.part1.name')(someObject);

Here is a simple fiddle demo: https://jsfiddle.net/harishanchu/oq5esowf/

. is a shorthand for the current directory and is used in Linux and Unix to execute a compiled program in the current directory. That is why you don't see this used in Web Development much except by open source, non-Windows frameworks like Google Angular which was written by people stuck on open source platforms.

./ also resolves to the current directory and is atypical in Web but supported as a path in some open source frameworks. Because it resolves the same as no path to the current file directory its not used. Example: ./image.jpg = image.jpg. Again, this is a relic of Unix operating systems that need path resolutions like this to run executables and resolve paths for security reasons. Its not a typical web path. That is why this syntax is redundant.

../ is a traditional web path that goes one directory up

/ is the ROOT of your website

These path resolutions below are true...

./folder= folder this is always true in web path resolution

./file.html = file.html this is always true in web path resolution

./ = {no path} an empty path is the same as ./ in the web world

{no path} = / an empty path is the same as the web root if your file is in the root directory

./ = / ONLY if you are in the root folder

../ = / ONLY if you are one folder below the web root

Use the Path class from System.IO. It contains useful calls for manipulating file paths, including GetDirectoryName which does what you want, returning the directory portion of the file path.

Usage is simple.

string directoryPath = Path.GetDirectoryName(filePath);

Purely compile time solution here. It's based on the fact that sizeof() of a string literal returns its length+1.

#define STRIPPATH(s)\
    (sizeof(s) > 2 && (s)[sizeof(s)-2] == '/' ? (s) + sizeof(s) - 1 : \
    sizeof(s) > 3 && (s)[sizeof(s)-3] == '/' ? (s) + sizeof(s) - 2 : \
    sizeof(s) > 4 && (s)[sizeof(s)-4] == '/' ? (s) + sizeof(s) - 3 : \
    sizeof(s) > 5 && (s)[sizeof(s)-5] == '/' ? (s) + sizeof(s) - 4 : \
    sizeof(s) > 6 && (s)[sizeof(s)-6] == '/' ? (s) + sizeof(s) - 5 : \
    sizeof(s) > 7 && (s)[sizeof(s)-7] == '/' ? (s) + sizeof(s) - 6 : \
    sizeof(s) > 8 && (s)[sizeof(s)-8] == '/' ? (s) + sizeof(s) - 7 : \
    sizeof(s) > 9 && (s)[sizeof(s)-9] == '/' ? (s) + sizeof(s) - 8 : \
    sizeof(s) > 10 && (s)[sizeof(s)-10] == '/' ? (s) + sizeof(s) - 9 : \
    sizeof(s) > 11 && (s)[sizeof(s)-11] == '/' ? (s) + sizeof(s) - 10 : (s))

#define __JUSTFILE__ STRIPPATH(__FILE__)

Feel free to extend the conditional operator cascade to the maximum sensible file name in the project. Path length doesn't matter, as long as you check far enough from the end of the string.

I'll see if I can get a similar macro with no hard-coded length with macro recursion...

The express.static middleware is separate from res.sendFile, so initializing it with an absolute path to your public directory won't do anything to res.sendFile. You need to use an absolute path directly with res.sendFile. There are two simple ways to do it:

1. res.sendFile(path.join(__dirname, '../public', 'index1.html'));
2. res.sendFile('index1.html', { root: path.join(__dirname, '../public') });

Note: __dirname returns the directory that the currently executing script is in. In your case, it looks like server.js is in app/. So, to get to public, you'll need back out one level first: ../public/index1.html.

Note: path is a built-in module that needs to be required for the above code to work: var path = require('path');

Easiest way is to open CMD or powershell as administrator and type

set PATH=%PATH%;C:\Python27

To use quotes just for completeness.

"/Users/my/work/a project with space"/**

If not recursive, remove the /**

1) Server.MapPath(".") -- Returns the "Current Physical Directory" of the file (e.g. aspx) being executed.

Ex. Suppose D:\WebApplications\Collage\Departments

2) Server.MapPath("..") -- Returns the "Parent Directory"

Ex. D:\WebApplications\Collage

3) Server.MapPath("~") -- Returns the "Physical Path to the Root of the Application"

Ex. D:\WebApplications\Collage

4) Server.MapPath("/") -- Returns the physical path to the root of the Domain Name

Ex. C:\Inetpub\wwwroot

You can quote the entire path as in windows or you can escape the spaces like in:

/foo\ folder\ with\ space/foo.sh -help

Both ways will work!

One way is to get system properties that give you the path separator for the operating system, this tutorial explains how. You can then use a standard string join using the file.separator.

I came across this when facing a similar problem, except I needed to check if a path is for a file or folder when that file or folder may not actually exist. There were a few comments on answers above that mentioned they would not work for this scenario. I found a solution (I use VB.NET, but you can convert if you need) that seems to work well for me:

Dim path As String = "myFakeFolder\ThisDoesNotExist\"
Dim bIsFolder As Boolean = (IO.Path.GetExtension(path) = "")
'returns True

Dim path As String = "myFakeFolder\ThisDoesNotExist\File.jpg"
Dim bIsFolder As Boolean = (IO.Path.GetExtension(path) = "")
'returns False

Hopefully this can be helpful to someone!

I did this and it works on osx:

lunch your terminal

 nano ~/.bash_profile 

And paste

 export PATH=~/.composer/vendor/bin:$PATH

press control + x

press the y key

press the return / enter key

If you download the 64 bit version of Eclipse; it will look for the 64 bit version of JRE. If you download the 32 bit version of Eclipse; it will look for the 32 bit version of JRE

What I did was to install the both the 32 and 64 bit version of JRE. You can get that from the SUN Oracle site. The JAVA site seems to automatically install the 32 bit version of Java. I guess that's because of the web browser.

Incase any one still wondering how to add environment variables then please use this link to add variables. Link: https://sqlbackupandftp.com/blog/setting-windows-path-for-postgres-tools

The problem with __FILE__ is that it will print the core module ".pm" path not necessarily the ".cgi" or ".pl" script path that is running. I guess it depends on what your goal is.

It seems to me that Cwd just needs to be updated for mod_perl. Here is my suggestion:

my $path;

use File::Basename;
my $file = basename($ENV{SCRIPT_NAME});

if (exists $ENV{MOD_PERL} && ($ENV{MOD_PERL_API_VERSION} < 2)) {
  if ($^O =~/Win/) {
    $path = `echo %cd%`;
    chop $path;
    $path =~ s!\\!/!g;
    $path .= $ENV{SCRIPT_NAME};
  }
  else {
    $path = `pwd`;
    $path .= "/$file";
  }
  # add support for other operating systems
}
else {
  require Cwd;
  $path = Cwd::getcwd()."/$file";
}
print $path;

Please add any suggestions.

Use INSTALLLOCATION. When you have problems, use the /lv log.txt to dump verbose logs. The logs would tell you if there is a property change that would override your own options. If you already installed the product, then a second run might just update it without changing the install location. You will have to uninstall first (use the /x option).

If you can live with multiple output paths having the same level of depth and folder structure there is a way to do this in webpack 2 (have yet to test with webpack 1.x)

Basically you don't follow the doc rules and you provide a path for the filename.

module.exports = {
    entry: {
      foo: 'foo.js',
      bar: 'bar.js'
    },

    output: {
      path: path.join(__dirname, 'components'),
      filename: '[name]/dist/[name].bundle.js', // Hacky way to force webpack   to have multiple output folders vs multiple files per one path
    }
};

That will take this folder structure

/-
  foo.js
  bar.js

And turn it into

/-
  foo.js
  bar.js
  components/foo/dist/foo.js
  components/bar/dist/bar.js

I read this question looking for an answer, and didn't like any of them.

So I wrote a quick and dirty solution. Just put this somewhere on your sys.path, and it'll add any directory under folder (from the current working directory), or under abspath:

#using.py

import sys, os.path

def all_from(folder='', abspath=None):
    """add all dirs under `folder` to sys.path if any .py files are found.
    Use an abspath if you'd rather do it that way.

    Uses the current working directory as the location of using.py. 
    Keep in mind that os.walk goes *all the way* down the directory tree.
    With that, try not to use this on something too close to '/'

    """
    add = set(sys.path)
    if abspath is None:
        cwd = os.path.abspath(os.path.curdir)
        abspath = os.path.join(cwd, folder)
    for root, dirs, files in os.walk(abspath):
        for f in files:
            if f[-3:] in '.py':
                add.add(root)
                break
    for i in add: sys.path.append(i)

>>> import using, sys, pprint
>>> using.all_from('py') #if in ~, /home/user/py/
>>> pprint.pprint(sys.path)
[
#that was easy
]

And I like it because I can have a folder for some random tools and not have them be a part of packages or anything, and still get access to some (or all) of them in a couple lines of code.

Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"JukeboxV2.0\JukeboxV2.0\Datos\ich will.mp3")

base directory + your filename

You can use a full path with the fstream classes. The folowing code attempts to open the file demo.txt in the root of the C: drive. Note that as this is an input operation, the file must already exist.

#include <fstream>
#include <iostream>
using namespace std;

int main() {
   ifstream ifs( "c:/demo.txt" );       // note no mode needed
   if ( ! ifs.is_open() ) {                 
      cout <<" Failed to open" << endl;
   }
   else {
      cout <<"Opened OK" << endl;
   }
}

What does this code produce on your system?

Have tried several of the solutions up there but none yielded correct results for the (probably special) case that the runnable jar has been exported with "Packaging external libraries" in Eclipse. For some reason all solutions based on the ProtectionDomain do result in null in that case.

From combining some solutions above I managed to achieve the following working code:

String surroundingJar = null;

// gets the path to the jar file if it exists; or the "bin" directory if calling from Eclipse
String jarDir = new File(ClassLoader.getSystemClassLoader().getResource(".").getPath()).getAbsolutePath();

// gets the "bin" directory if calling from eclipse or the name of the .jar file alone (without its path)
String jarFileFromSys = System.getProperty("java.class.path").split(";")[0];

// If both are equal that means it is running from an IDE like Eclipse
if (jarFileFromSys.equals(jarDir))
{
    System.out.println("RUNNING FROM IDE!");
    // The path to the jar is the "bin" directory in that case because there is no actual .jar file.
    surroundingJar = jarDir;
}
else
{
    // Combining the path and the name of the .jar file to achieve the final result
    surroundingJar = jarDir + jarFileFromSys.substring(1);
}

System.out.println("JAR File: " + surroundingJar);

In Python, paths are relative to the current working directory, which in most cases is the directory from which you run your program. The current working directory is very likely not as same as the directory of your module file, so using a path relative to your current module file is always a bad choice.

Using absolute path should be the best solution:

import os
package_dir = os.path.dirname(os.path.abspath(__file__))
thefile = os.path.join(package_dir,'test.cvs')

You can use:

setx PATH "%PATH%;C:\\Something\\bin"

However, setx will truncate the stored string to 1024 bytes, potentially corrupting the PATH.

/M will change the PATH in HKEY_LOCAL_MACHINE instead of HKEY_CURRENT_USER. In other words, a system variable, instead of the user's. For example:

SETX /M PATH "%PATH%;C:\your path with spaces"

You have to keep in mind, the new PATH is not visible in your current cmd.exe.

But if you look in the registry or on a new cmd.exe with "set p" you can see the new value.

write that on your Command Prompt:

set Path=%path%

Replace %path% by the Path of your Python Folder Example:

set Path=C:/Python27

So basically you want to find a file in mounted filesystem (not necessarily in PATH directories only) and check if it is executable. This translates to following plan:

• enumerate all files in locally mounted filesystems
• match results with name pattern
• for each file found check if it is executable

I'd say, doing this in a portable way will require lots of computing power and time. Is it really what you need?

string result = Path.GetTempPath();

https://docs.microsoft.com/en-us/dotnet/api/system.io.path.gettemppath

Psuedo-code:

1. Split the strings by the path seperator ("/")
2. Find the greatest common path by iterating thru the result of the split string (so you'd end up with "/var/data" or "/a" in your two examples)
3. return "." + whicheverPathIsLonger.substring(commonPath.length);

Starting with Python 3.4, one can use the glob() method of one of the Path classes in the new pathlib module, which supports ** wildcards. For example:

from pathlib import Path

for file_path in Path('src').glob('**/*.c'):
    print(file_path) # do whatever you need with these files

Update: Starting with Python 3.5, the same syntax is also supported by glob.glob().

In case you'd like to paste windows path from other source (say, File Explorer) - you can do so via input() call in python console:

>>> input()
D:\EP\stuff\1111\this_is_a_long_path\you_dont_want\to_type\or_edit_by_hand
'D:\\EP\\stuff\\1111\\this_is_a_long_path\\you_dont_want\\to_type\\or_edit_by_hand'

Then just copy the result

Path.GetFileName

Path.GetFileNameWithoutExtension

The Path class is wonderful.

I have placed the following script on my system & I call it as a bash alias for when I want to quickly grab the full path to a file in the current dir:

#!/bin/bash
/usr/bin/find "$PWD" -maxdepth 1 -mindepth 1 -name "$1"

I am not sure why, but, on OS X when called by a script "$PWD" expands to the absolute path. When the find command is called on the command line, it doesn't. But it does what I want... enjoy.

Can't you just add a reference to System.Web and then you can use Server.MapPath ?

Edit: Nowadays I'd recommend using the HostingEnvironment.MapPath Method:

It's a static method in System.Web assembly that Maps a virtual path to a physical path on the server. It doesn't require a reference to HttpContext.

If your tiles are not in your bundle, either copied from the bundle or downloaded from the internet you can get the directory like this

NSString *documentdir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *tileDirectory = [documentdir stringByAppendingPathComponent:@"xxxx/Tiles"];
NSLog(@"Tile Directory: %@", tileDirectory);

open bash profile in textEdit

open -e .bash_profile

Edit file or paste in front of PATH export PATH=/usr/bin:/usr/sbin:/bin:/sbin:/usr/local/bin:/usr/local/sbin:~/bin

save & close the file

*To open .bash_profile directly open textEdit > file > recent

Console.WriteLine(Path.GetDirectoryName(@"C:\hello\my\dear\world.hm")); 

I used below regex to get that result also when its finished by a \

(\\[^\\]+)\\?$

Instead of using

import os
dirname = os.path.dirname(__file__)
filename = os.path.join(dirname, 'relative/path/to/file/you/want')

as in the accepted answer, it would be more robust to use:

import inspect
import os
dirname = os.path.dirname(os.path.abspath(inspect.stack()[0][1]))
filename = os.path.join(dirname, 'relative/path/to/file/you/want')

because using __file__ will return the file from which the module was loaded, if it was loaded from a file, so if the file with the script is called from elsewhere, the directory returned will not be correct.

These answers give more detail: https://stackoverflow.com/a/31867043/5542253 and https://stackoverflow.com/a/50502/5542253

Well I figured it out that this attribute display image when the full location is provided in it. I simply uploaded that image on my server and linked the location of that image in the background-image:url("xxxxx.xxx"); attribute and it finally worked but if you guys don't have server then try to enter the complete location of the image in the attribute by going in property of that image. Although i was using this attribute in tag of an HTML file but it will surely works on CSS file too. If that method didn't work then try to upload your image on internet like behance, facebook, instagram,etc and inspect the image and copy that location to your attribute.. Hope This will work

I had to open Android studio and go through the wizard. Android studio will install the SDK for you.

In a command prompt you tell Cmd to use Windows Explorer's command line by prefacing it with start.

So start Yourbatchname.

Note you have to register as if its name is batchfile.exe.

Programs and documents can be added to the registry so typing their name without their path in the Start - Run dialog box or shortcut enables Windows to find them.

This is a generic reg file. Copy the lines below to a new Text Document and save it as anyname.reg. Edit it with your programs or documents.

In paths, use \\ to separate folder names in key paths as regedit uses a single \ to separate its key names. All reg files start with REGEDIT4. A semicolon turns a line into a comment. The @ symbol means to assign the value to the key rather than a named value.

The file doesn't have to exist. This can be used to set Word.exe to open Winword.exe.

Typing start batchfile will start iexplore.exe.

REGEDIT4
;The bolded name below is the name of the document or program, <filename>.<file extension>

[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\App Paths\Batchfile.exe]

; The @ means the path to the file is assigned to the default value for the key.
; The whole path in enclosed in a quotation mark ".

@="\"C:\\Program Files\\Internet Explorer\\iexplore.exe\""

; Optional Parameters. The semicolon means don't process the line. Remove it if you want to put it in the registry

; Informs the shell that the program accepts URLs.

;"useURL"="1"

; Sets the path that a program will use as its' default directory. This is commented out.

;"Path"="C:\\Program Files\\Microsoft Office\\Office\\"

You've already been told about path in another answer. Also see doskey /? for cmd macros (they only work when typing).

You can run startup commands for CMD. From Windows Resource Kit Technical Reference

AutoRun

HKCU\Software\Microsoft\Command Processor

On Windows, I have found that the important thing is to start Eclipse from the command line rather than from the Start Menu or a shortcut, provided that the native DLL is in a directory in your PATH. Apparently, this ensures that the proper directory is on the path.

this solution is robust even in executables

import inspect, os.path

filename = inspect.getframeinfo(inspect.currentframe()).filename
path     = os.path.dirname(os.path.abspath(filename))

You mistyped the set command – you missed the backslash after C:. It should be:

C:\>set path=C:\Program Files (x86)\Java\jdk1.7.0\bin

import os
os.listdir("path") # returns list

I liked steamer25's solution as it seems the most robust for my purposes. However, when debugging in RStudio (in windows), the path would not get set properly. The reason being that if a breakpoint is set in RStudio, sourcing the file uses an alternate "debug source" command which sets the script path a little differently. Here is the final version which I am currently using which accounts for this alternate behavior within RStudio when debugging:

# @return full path to this script
get_script_path <- function() {
    cmdArgs = commandArgs(trailingOnly = FALSE)
    needle = "--file="
    match = grep(needle, cmdArgs)
    if (length(match) > 0) {
        # Rscript
        return(normalizePath(sub(needle, "", cmdArgs[match])))
    } else {
        ls_vars = ls(sys.frames()[[1]])
        if ("fileName" %in% ls_vars) {
            # Source'd via RStudio
            return(normalizePath(sys.frames()[[1]]$fileName))

            # Source'd via R console
            return(normalizePath(sys.frames()[[1]]$ofile))
        }
    }
}

Just like any other environment variable, with SET:

SET PATH=%PATH%;c:\whatever\else

If you want to have a little safety check built in first, check to see if the new path exists first:

IF EXIST c:\whatever\else SET PATH=%PATH%;c:\whatever\else

If you want that to be local to that batch file, use setlocal:

setlocal
set PATH=...
set OTHERTHING=...

@REM Rest of your script

Read the docs carefully for setlocal/endlocal , and have a look at the other references on that site - Functions is pretty interesting too and the syntax is tricky.

The Syntax page should get you started with the basics.

you can set it in .bashrc

PATH=$PATH:/opt/ActiveTcl-8.5/bin;export PATH;

I would personally recommend that you use os.path.isdir() to test instead of os.path.exists().

>>> os.path.exists('/tmp/dirname')
True
>>> os.path.exists('/tmp/dirname/filename.etc')
True
>>> os.path.isdir('/tmp/dirname/filename.etc')
False
>>> os.path.isdir('/tmp/fakedirname')
False

If you have:

>>> dir = raw_input(":: ")

And a foolish user input:

:: /tmp/dirname/filename.etc

... You're going to end up with a directory named filename.etc when you pass that argument to os.makedirs() if you test with os.path.exists().

one of the answers that exist on the current page (this), is correct but it has some mistakes. for example, it won't work on devices with API 29+. I'll update the above code and post its new version. I think this post should be marked as the final answer.

Updated code: (Added WhatsApp support)

As many have suggested, JRE v1.7 and above has File.toPath();

File yourFile = ...;
Path yourPath = yourFile.toPath();

On Oracle's jdk 1.7 documentation which is also mentioned in other posts above, the following equivalent code is described in the description for toPath() method, which may work for JRE v1.6;

File yourFile = ...;
Path yourPath = FileSystems.getDefault().getPath(yourFile.getPath());

For older versions of windows (2k, 2k3, xp)

"%Userprofile%\Local Settings\Application Data\Google\Chrome\User Data\Default\Extensions" 

you can try to this , then you get a bitmap of selected image and then you can easily find it's native path from Device Default Gallery.

Bitmap roughBitmap= null;
    try {
    // Works with content://, file://, or android.resource:// URIs
    InputStream inputStream =
    getContentResolver().openInputStream(uri);
    roughBitmap= BitmapFactory.decodeStream(inputStream);

    // calc exact destination size
    Matrix m = new Matrix();
    RectF inRect = new RectF(0, 0, roughBitmap.Width, roughBitmap.Height);
    RectF outRect = new RectF(0, 0, dstWidth, dstHeight);
    m.SetRectToRect(inRect, outRect, Matrix.ScaleToFit.Center);
    float[] values = new float[9];
    m.GetValues(values);


    // resize bitmap if needed
    Bitmap resizedBitmap = Bitmap.CreateScaledBitmap(roughBitmap, (int) (roughBitmap.Width * values[0]), (int) (roughBitmap.Height * values[4]), true);

    string name = "IMG_" + new Java.Text.SimpleDateFormat("yyyyMMdd_HHmmss").Format(new Java.Util.Date()) + ".png";
    var sdCardPath= Environment.GetExternalStoragePublicDirectory("DCIM").AbsolutePath;

    var filePath = System.IO.Path.Combine(sdCardPath, name);
    } catch (FileNotFoundException e) {

In your MakeFile or CMakeLists.txt you can set CMAKE_CXX_FLAGS as below:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/path/to/your/folder")

In python there is no difference between modules and scripts; You can execute both scripts and modules. The file must be on the pythonpath AFAIK because python must be able to find the file in question. If python is executed from a directory, then the directory is automatically added to the pythonpath.

Refer to What is the best way to call a Python script from another Python script? for more information about modules vs scripts

There is also a builtin function execfile(filename) that will do what you want

I spent a while messing around with this problem, because no solution I found actually worked, strangely enough! The working directory is frequently not the directory of the JAR, especially if a JAR (or any program, for that matter) is run from the Start Menu under Windows. So here is what I did, and it works for .class files run from outside a JAR just as well as it works for a JAR. (I only tested it under Windows 7.)

try {
    //Attempt to get the path of the actual JAR file, because the working directory is frequently not where the file is.
    //Example: file:/D:/all/Java/TitanWaterworks/TitanWaterworks-en.jar!/TitanWaterworks.class
    //Another example: /D:/all/Java/TitanWaterworks/TitanWaterworks.class
    PROGRAM_DIRECTORY = getClass().getClassLoader().getResource("TitanWaterworks.class").getPath(); // Gets the path of the class or jar.

    //Find the last ! and cut it off at that location. If this isn't being run from a jar, there is no !, so it'll cause an exception, which is fine.
    try {
        PROGRAM_DIRECTORY = PROGRAM_DIRECTORY.substring(0, PROGRAM_DIRECTORY.lastIndexOf('!'));
    } catch (Exception e) { }

    //Find the last / and cut it off at that location.
    PROGRAM_DIRECTORY = PROGRAM_DIRECTORY.substring(0, PROGRAM_DIRECTORY.lastIndexOf('/') + 1);
    //If it starts with /, cut it off.
    if (PROGRAM_DIRECTORY.startsWith("/")) PROGRAM_DIRECTORY = PROGRAM_DIRECTORY.substring(1, PROGRAM_DIRECTORY.length());
    //If it starts with file:/, cut that off, too.
    if (PROGRAM_DIRECTORY.startsWith("file:/")) PROGRAM_DIRECTORY = PROGRAM_DIRECTORY.substring(6, PROGRAM_DIRECTORY.length());
} catch (Exception e) {
    PROGRAM_DIRECTORY = ""; //Current working directory instead.
}

Sadly with OOTB tools, you cannot append either the system path or user path directly/easily. If you want to stick with OOTB tools, you have to query either the SYSTEM or USER path, save that value as a variable, then appends your additions and save it using setx. The two examples below show how to retrieve either, save them, and append your additions. Don't get mess with %PATH%, it is a concatenation of USER+SYSTEM, and will cause a lot of duplication in the result. You have to split them as shown below...

Append to System PATH

for /f "usebackq tokens=2,*" %A in (`reg query "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v PATH`) do set SYSPATH=%B

setx PATH "%SYSPATH%;C:\path1;C:\path2" /M

Append to User PATH

for /f "usebackq tokens=2,*" %A in (`reg query HKCU\Environment /v PATH`) do set userPATH=%B

setx PATH "%userPATH%;C:\path3;C:\path4"

My issue turned out to be embarrassingly simple:

Restart command prompt and the new variables should update

private bool IsValidPath(string path)
{
    Regex driveCheck = new Regex(@"^[a-zA-Z]:\\$");
    if (!driveCheck.IsMatch(path.Substring(0, 3))) return false;
    string strTheseAreInvalidFileNameChars = new string(Path.GetInvalidPathChars());
    strTheseAreInvalidFileNameChars += @":/?*" + "\"";
    Regex containsABadCharacter = new Regex("[" + Regex.Escape(strTheseAreInvalidFileNameChars) + "]");
    if (containsABadCharacter.IsMatch(path.Substring(3, path.Length - 3)))
        return false;

    DirectoryInfo dir = new DirectoryInfo(Path.GetFullPath(path));
    if (!dir.Exists)
        dir.Create();
    return true;
}

<a href="./">Folder</a>

Here's a little cmd script you can copy-n-paste into a file named something like where.cmd:

@echo off
rem - search for the given file in the directories specified by the path, and display the first match
rem
rem    The main ideas for this script were taken from Raymond Chen's blog:
rem
rem         http://blogs.msdn.com/b/oldnewthing/archive/2005/01/20/357225.asp
rem
rem
rem - it'll be nice to at some point extend this so it won't stop on the first match. That'll
rem     help diagnose situations with a conflict of some sort.
rem

setlocal

rem - search the current directory as well as those in the path
set PATHLIST=.;%PATH%
set EXTLIST=%PATHEXT%

if not "%EXTLIST%" == "" goto :extlist_ok
set EXTLIST=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH
:extlist_ok

rem - first look for the file as given (not adding extensions)
for %%i in (%1) do if NOT "%%~$PATHLIST:i"=="" echo %%~$PATHLIST:i

rem - now look for the file adding extensions from the EXTLIST
for %%e in (%EXTLIST%) do @for %%i in (%1%%e) do if NOT "%%~$PATHLIST:i"=="" echo %%~$PATHLIST:i

If you're using Windows 10, do this:

1. Go to Start

2. Start typing 'This PC'

3. Right-click This PC, choose Properties

4. On the left side of the window that pops up, click on Advanced System Settings

5. Click on the Advanced tab

6. Click on the Environmental Variables button at the bottom

7. Down in the System Variables section, double-click Path

8. Click the New button in the top right corner

9. Add this path: C:\Program Files\Git\bin\ then click the enter key

10. Add another path: C:\Program Files\Git\cmd

11. Close & re-open the console if it's already open.

I stepped you through the long way so you gain exposure to the different Windows/menus. Good luck.

the recommended solution in the comments on the OpenSUSE distro suggests to change:

Defaults env_reset

to:

Defaults !env_reset

and then presumably to comment out the following line which isn't needed:

Defaults env_keep = "LANG LC_ADDRESS LC_CTYPE LC_COLLATE LC_IDENTIFICATION LC_MEASURE    MENT LC_MESSAGES LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE LC_TIME LC_ALL L    ANGUAGE LINGUAS XDG_SESSION_COOKIE"

Application.Current results in an appdomain http://msdn.microsoft.com/en-us/library/system.appdomain_members.aspx

Also this should give you the location of the assembly

AppDomain.CurrentDomain.BaseDirectory

I seem to recall there being multiple ways of getting the location of the application. but this one worked for me in the past atleast (it's been a while since i've done winforms programming :/)

If you just want to get the information of current directory, you can type:

pwd

and you don't need to use the Nautilus, or you can use a teamviewer software to remote connect to the computer, you can get everything you want.

If you want the exe path you can use System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly().Location);

It is always C:\Windows\System32\WindowsPowershell\v1.0. It was left like that for backward compability is what I heard or read somewhere.

Note: This answer addresses part of the problem. For a complete solution (in the form of a library), look at Paul Burke's answer.

You could use the URI to obtain document id, and then query either MediaStore.Images.Media.EXTERNAL_CONTENT_URI or MediaStore.Images.Media.INTERNAL_CONTENT_URI (depending on the SD card situation).

To get document id:

// Will return "image:x*"
String wholeID = DocumentsContract.getDocumentId(uriThatYouCurrentlyHave);

// Split at colon, use second item in the array
String id = wholeID.split(":")[1];

String[] column = { MediaStore.Images.Media.DATA };     

// where id is equal to             
String sel = MediaStore.Images.Media._ID + "=?";

Cursor cursor = getContentResolver().
                          query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, 
                          column, sel, new String[]{ id }, null);

String filePath = "";

int columnIndex = cursor.getColumnIndex(column[0]);

if (cursor.moveToFirst()) {
    filePath = cursor.getString(columnIndex);
}   

cursor.close();

Reference: I'm not able to find the post that this solution is taken from. I wanted to ask the original poster to contribute here. Will look some more tonight.

A proper solution is using a css class instead of writing src in js file. For example instead of using:

$(this).css("background", "url('../Images/filters_collapse.jpg')");

use:

$(this).addClass("xxx");

and in a css file that is loaded in the page write:

.xxx {
  background-image:url('../Images/filters_collapse.jpg');
}

System apps installed /system/app/ or /system/priv-app. Other apps can be installed in /data/app or /data/preload/.

Connect to your android mobile with USB and run the following commands. You will see all the installed packages.

$ adb shell 

$ pm list packages -f

First of all we will get source and destination points between which we have to draw route. Then we will pass these attribute to below function.

 public String makeURL (double sourcelat, double sourcelog, double destlat, double destlog ){
        StringBuilder urlString = new StringBuilder();
        urlString.append("http://maps.googleapis.com/maps/api/directions/json");
        urlString.append("?origin=");// from
        urlString.append(Double.toString(sourcelat));
        urlString.append(",");
        urlString.append(Double.toString( sourcelog));
        urlString.append("&destination=");// to
        urlString.append(Double.toString( destlat));
        urlString.append(",");
        urlString.append(Double.toString( destlog));
        urlString.append("&sensor=false&mode=driving&alternatives=true");
        urlString.append("&key=YOUR_API_KEY");
        return urlString.toString();
 }

This function will make the url that we will send to get Direction API response. Then we will parse that response . The parser class is

public class JSONParser {

    static InputStream is = null;
    static JSONObject jObj = null;
    static String json = "";
    // constructor
    public JSONParser() {
    }
    public String getJSONFromUrl(String url) {

        // Making HTTP request
        try {
            // defaultHttpClient
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);

            HttpResponse httpResponse = httpClient.execute(httpPost);
            HttpEntity httpEntity = httpResponse.getEntity();
            is = httpEntity.getContent();           

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "iso-8859-1"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }

            json = sb.toString();
            is.close();
        } catch (Exception e) {
            Log.e("Buffer Error", "Error converting result " + e.toString());
        }
        return json;

    }
}

This parser will return us string. We will call it like that.

JSONParser jParser = new JSONParser();
String json = jParser.getJSONFromUrl(url);

Now we will send this string to our drawpath function. The drawpath function is

public void drawPath(String  result) {

    try {
            //Tranform the string into a json object
           final JSONObject json = new JSONObject(result);
           JSONArray routeArray = json.getJSONArray("routes");
           JSONObject routes = routeArray.getJSONObject(0);
           JSONObject overviewPolylines = routes.getJSONObject("overview_polyline");
           String encodedString = overviewPolylines.getString("points");
           List<LatLng> list = decodePoly(encodedString);
           Polyline line = mMap.addPolyline(new PolylineOptions()
                                    .addAll(list)
                                    .width(12)
                                    .color(Color.parseColor("#05b1fb"))//Google maps blue color
                                    .geodesic(true)
                    );
           /*
           for(int z = 0; z<list.size()-1;z++){
                LatLng src= list.get(z);
                LatLng dest= list.get(z+1);
                Polyline line = mMap.addPolyline(new PolylineOptions()
                .add(new LatLng(src.latitude, src.longitude), new LatLng(dest.latitude,   dest.longitude))
                .width(2)
                .color(Color.BLUE).geodesic(true));
            }
           */
    } 
    catch (JSONException e) {

    }
} 

Above code will draw the path on mMap. The code of decodePoly is

private List<LatLng> decodePoly(String encoded) {

    List<LatLng> poly = new ArrayList<LatLng>();
    int index = 0, len = encoded.length();
    int lat = 0, lng = 0;

    while (index < len) {
        int b, shift = 0, result = 0;
        do {
            b = encoded.charAt(index++) - 63;
            result |= (b & 0x1f) << shift;
            shift += 5;
        } while (b >= 0x20);
        int dlat = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
        lat += dlat;

        shift = 0;
        result = 0;
        do {
            b = encoded.charAt(index++) - 63;
            result |= (b & 0x1f) << shift;
            shift += 5;
        } while (b >= 0x20);
        int dlng = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
        lng += dlng;

        LatLng p = new LatLng( (((double) lat / 1E5)),
                 (((double) lng / 1E5) ));
        poly.add(p);
    }

    return poly;
}

As direction call may take time so we will do all this in Asynchronous task. My Asynchronous task was

private class connectAsyncTask extends AsyncTask<Void, Void, String>{
    private ProgressDialog progressDialog;
    String url;
    connectAsyncTask(String urlPass){
        url = urlPass;
    }
    @Override
    protected void onPreExecute() {
        // TODO Auto-generated method stub
        super.onPreExecute();
        progressDialog = new ProgressDialog(MainActivity.this);
        progressDialog.setMessage("Fetching route, Please wait...");
        progressDialog.setIndeterminate(true);
        progressDialog.show();
    }
    @Override
    protected String doInBackground(Void... params) {
        JSONParser jParser = new JSONParser();
        String json = jParser.getJSONFromUrl(url);
        return json;
    }
    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);   
        progressDialog.hide();        
        if(result!=null){
            drawPath(result);
        }
    }
}

I hope it will help.

A better way, use getParent() from File Class..

String a="/root/sdcard/Pictures/img0001.jpg"; // A valid file path 
File file = new File(a); 
String getDirectoryPath = file.getParent(); // Only return path if physical file exist else return null

http://developer.android.com/reference/java/io/File.html#getParent%28%29

I have resolved this problem by adding or changing variables in environment variables. Go to Win7 -> My Computer - > Properties - > Advanced system settings -> environment Variables

1. If there is no variable JAVA_HOME, add it with value of variable, with route to folder where your JDK installed, for examle C:\Program Files\Java\jdk-11.0.2
2. If there is no variable PATH or it have another value, change the value of variable to C:\Program Files\Java\jdk-11.0.2\bin or add variable PATH with this value

Good Luck

os.path.realpath(__file__) will give you the path of the current file, resolving any symlinks in the path. This works fine on my mac.

Here is my little utility helper for splitting paths int file, path tokens:

import os    
# usage: file, path = splitPath(s)
def splitPath(s):
    f = os.path.basename(s)
    p = s[:-(len(f))-1]
    return f, p

Java binaries may be under "Program Files" or "Program Files (x86)": those white spaces will likely affect the behaviour.

In order to set up env variables correctly, I suggest gathering some info before starting:

• Open DOS shell (type cmd into 'RUN' box) go to C:\
• type "dir /x" and take note of DOS names (with ~) for "Program Files *" folders

Cygwin configuration:

go under C:\cygwin\home\, then open .bash_profile and add the following two lines (conveniently customized in order to match you actual JDK path)

export JAVA_HOME="/cygdrive/c/PROGRA~1/Java/jdk1.8.0_65"
export PATH="$JAVA_HOME/bin:$PATH"

Now from Cygwin launch

javac -version

to check if the configuration is successful.

I use:

ps -ef | grep 786

Replace 786 with your PID or process name.

This gives you the root folder:

System.AppDomain.CurrentDomain.BaseDirectory

You can navigate from here using .. or ./ etc.. , Appending .. takes you to folder where .sln file can be found

For .NET framework (thanks to Adiono comment)

Path.GetFullPath(Path.Combine(AppDomain.CurrentDomain.BaseDirectory,"..\\..\\"))

For .NET core here is a way to do it (thanks to nopara73 comment)

Path.GetFullPath(Path.Combine(AppContext.BaseDirectory, "..\\..\\..\\")) ;

I tend to find this neat

sudo mkdir -p /etc/paths.d   # was optional in my case
echo /usr/local/git/bin  | sudo tee /etc/paths.d/mypath1

Instructions:

1. Click on the Terminal icon in the desktop panel to open a terminal window and access the command prompt.
2. Type the command which java to find the path to the Java executable file.
3. Type the command su - to become the root user.
4. Type the command vi /root/.bash_profile to open the system bash_profile file in the Vi text editor. You can replace vi with your preferred text editor.
5. Type export JAVA_HOME=/usr/local/java/ at the bottom of the file. Replace /usr/local/java with the location found in step two.
6. Save and close the bash_profile file.
7. Type the command exit to close the root session.
8. Log out of the system and log back in.
9. Type the command echo $JAVA_HOME to ensure that the path was set correctly.

set java_home in centos

No other solutions were working for me, so I tried:

pip uninstall <module> && pip install <module>

And that resolved it for me. Your mileage may vary.

This is the cleanest approach

let dat = new Date() _x000D_
let copyOf = new Date(dat.valueOf())_x000D_
_x000D_
console.log(dat);_x000D_
console.log(copyOf);

Since functions in Javascript are first-class object, by defining it that way, it effectively defines a "class" much like C++ or C#.

That function can define local variables, and have functions within it. The internal functions (effectively instance methods) will have access to the local variables (effectively instance variables), but they will be isolated from the rest of the script.

You can create dynamically like the below code:

JSONObject jsonBody = new JSONObject();
try {
    jsonBody.put("username", userName);
    jsonBody.put("email", email);
    jsonBody.put("phone", contactNumber);
    jsonBody.put("password", password);
    jsonBody.put("carType", carType);
    jsonBody.put("fcmToken", "lljlkdsajfljasldfj;lsa");
    jsonBody.put("profilePhoto", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg");

    JSONObject document = new JSONObject();

    try {
        document.put("DL", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
        document.put("Registration", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
        document.put("Insurance", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
        document.put("CarInside", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
        document.put("CarOutside", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
    } catch (JSONException e) {
        e.printStackTrace();
    }

    jsonBody.put("documents", document.toString());

    Log.i("MAHDI", "Hello: Mahdi: Data: " + jsonBody);
} catch (JSONException e) {
    e.printStackTrace();
}

And the createDocument method code:

public JSONArray createDocument(String id, String imageUrl) {

JSONObject dlObject = new JSONObject();
try {
    dlObject.put("_id", id);
    dlObject.put("uriPath", imageUrl);
} catch (JSONException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
JSONArray dlArray = new JSONArray();
dlArray.put(dlObject);

return dlArray;
}

If you would like to handle multiple inputs with one handler take a look at my approach where I'm using computed property to get value of the input based on it's name.

import React, { useState } from "react";
import "./style.css";

export default function App() {
  const [state, setState] = useState({
    name: "John Doe",
    email: "[email protected]"
  });

  const handleChange = e => {
    setState({
      [e.target.name]: e.target.value
    });
  };

  return (
    <div>
      <input
        type="text"
        className="name"
        name="name"
        value={state.name}
        onChange={handleChange}
      />

      <input
        type="text"
        className="email"
        name="email"
        value={state.email}
        onChange={handleChange}
      />
    </div>
  );
}

Change the file content of c:\wamp\alias\phpmyadmin.conf to the following.

Note: You should set the Allow Directive to allow from your local machine for security purposes. The directive Allow from all is insecure and should be limited to your local machine.

<Directory "c:/wamp/apps/phpmyadmin3.4.5/">
    Options Indexes FollowSymLinks MultiViews
    AllowOverride all
        Order Deny,Allow
        Allow from all
</Directory>

Here my WAMP installation is in the c:\wamp folder. Change it according to your installation.

Previously, it was like this:

<Directory "c:/wamp/apps/phpmyadmin3.4.5/">
    Options Indexes FollowSymLinks MultiViews
    AllowOverride all
        Order Deny,Allow
    Deny from all
    Allow from 127.0.0.1
</Directory>

Modern versions of Apache 2.2 and up will look for a IPv6 loopback instead of a IPv4 loopback (your localhost).

The real problem is that wamp is binding to an IPv6 address. The fix: just add Allow from ::1 - Tiberiu-Ionu? Stan

<Directory "c:/wamp22/apps/phpmyadmin3.5.1/">
    Options Indexes FollowSymLinks MultiViews
    AllowOverride all
        Order Deny,Allow
    Deny from all
    Allow from localhost 127.0.0.1 ::1
</Directory>

This will allow only the local machine to access local apps for Apache.

Restart your Apache server after making these changes.

Thanks to duncan answer, I end up with this:

marker.addListener('mouseover', () => infoWindow.open(map, marker))
marker.addListener('mouseout', () => infoWindow.close())

Save Bitmap to your Gallery Without Compress.

private File saveBitMap(Context context, Bitmap Final_bitmap) {
    File pictureFileDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "Your Folder Name");
    if (!pictureFileDir.exists()) {
        boolean isDirectoryCreated = pictureFileDir.mkdirs();
        if (!isDirectoryCreated)
            Log.i("TAG", "Can't create directory to save the image");
        return null;
    }
    String filename = pictureFileDir.getPath() + File.separator + System.currentTimeMillis() + ".jpg";
    File pictureFile = new File(filename);
    try {
        pictureFile.createNewFile();
        FileOutputStream oStream = new FileOutputStream(pictureFile);
        Final_bitmap.compress(Bitmap.CompressFormat.PNG, 100, oStream);
        oStream.flush();
        oStream.close();
        Toast.makeText(Full_Screen_Activity.this, "Save Image Successfully..", Toast.LENGTH_SHORT).show();
    } catch (IOException e) {
        e.printStackTrace();
        Log.i("TAG", "There was an issue saving the image.");
    }
    scanGallery(context, pictureFile.getAbsolutePath());
    return pictureFile;
}
private void scanGallery(Context cntx, String path) {
    try {
        MediaScannerConnection.scanFile(cntx, new String[]{path}, null, new MediaScannerConnection.OnScanCompletedListener() {
            public void onScanCompleted(String path, Uri uri) {
                Toast.makeText(Full_Screen_Activity.this, "Save Image Successfully..", Toast.LENGTH_SHORT).show();
            }
        });
    } catch (Exception e) {
        e.printStackTrace();
        Log.i("TAG", "There was an issue scanning gallery.");
    }
}

One way would be with sed. For example:

echo $name | sed -e 's?http://www\.??'

Normally the sed regular expressions are delimited by `/', but you can use '?' since you're searching for '/'. Here's another bash trick. @DigitalTrauma's answer reminded me that I ought to suggest it. It's similar:

echo ${name#http://www.}

(DigitalTrauma also gets credit for reminding me that the "http://" needs to be handled.)

The quickest way for me to fix it was to duplicate the affected folder, and commit it with an alternative name. Then svn mv duplicateFolder originalFolder. Pretty easy.

So, take folder1 and make a folder1Copy:

svn delete folder1
svn add folder1Copy

Commit and update:

svn mv folder1Copy/ folder1/

Commit again and it's fixed.

Proxy can work in the following way.

Step1, configure client to use proxyHost:proxyPort.

Proxy is a TCP server that is listening on proxyHost:proxyPort. Browser opens connection with Proxy and sends Http request. Proxy parses this request and tries to detect "Host" header. This header will tell Proxy where to open connection.

Step 2: Proxy opens connection to the address specified in the "Host" header. Then it sends HTTP request to that remote server. Reads response.

Step 3: After response is read from remote HTTP server, Proxy sends the response through an earlier opened TCP connection with browser.

Schematically it will look like this:

Browser                            Proxy                     HTTP server
  Open TCP connection  
  Send HTTP request  ----------->                       
                                 Read HTTP header
                                 detect Host header
                                 Send request to HTTP ----------->
                                 Server
                                                      <-----------
                                 Read response and send
                   <-----------  it back to the browser
Render content

I did a little research and was able to write this code:

strbody = "<BODY style=font-size:11pt;font-family:Calibri>Good Morning;<p>We have completed our main aliasing process for today.  All assigned firms are complete.  Please feel free to respond with any questions.<p>Thank you.</BODY>"

apparently by setting the "font-size=11pt" instead of setting the font size <font size=5>, It allows you to select a specific font size like you normally would in a text editor, as opposed to selecting a value from 1-7 like my code was originally.

This link from simpLE MAn gave me some good info.

it feels like it's stupid access the filesystem and get the contents for every subdirectory instead of getting everything at once.

Your feeling is wrong. That's how filesystems work. There is no faster way (except when you have to do this repeatedly or for different patterns, you can cache all the file paths in memory, but then you have to deal with cache invalidation i.e. what happens when files are added/removed/renamed while the app runs).

Found an answer myself, this blog helped: http://thingsyoudidntknowaboutjenkins.tumblr.com/post/23596855946/git-plugin-part-3

Basically need to execute:

git checkout master

before modifying any files

then

git commit -am "Updated version number"

after modified files

and then use post build action of Git Publisher with an option of Merge Results which will push changes to github on successful build.

You can set the row height by code

dataGridView.RowTemplate.Height = 35;

or by property panel

<?php 
    list($width, $height) = getimagesize("http://site.com/image.png"); 
    $arr = array('h' => $height, 'w' => $width );
?>

set vimdiff to ignore case

Having started vim diff with

 gvim -d main.sql backup.sql &

I find that annoyingly one file has MySQL keywords in lowercase the other uppercase showing differences on practically every other line

:set diffopt+=icase

this updates the screen dynamically & you can just as easily switch it off again

For those discovering this now and the above answers didn't work, the issue I had was the screen wasn't big enough. I added this when initializing my ChromeDriver, and it fixed the problem:

options.add_argument("window-size=1200x600")

I ran into the same problem and found out that the file name is required for httpclient 4.x to be working with PHP backend. It was not the case for httpclient 3.x.

So my solution is to add a name parameter in the FileBody constructor. ContentBody cbFile = new FileBody(file, "image/jpeg", "FILE_NAME");

Hope it helps.

Explanation of stereotypes :

• @Service - Annotate all your service classes with @Service. This layer knows the unit of work. All your business logic will be in Service classes. Generally methods of service layer are covered under transaction. You can make multiple DAO calls from service method, if one transaction fails all transactions should rollback.
• @Repository - Annotate all your DAO classes with @Repository. All your database access logic should be in DAO classes.
• @Component - Annotate your other components (for example REST resource classes) with component stereotype.
• @Autowired - Let Spring auto-wire other beans into your classes using @Autowired annotation.

@Component is a generic stereotype for any Spring-managed component. @Repository, @Service, and @Controller are specializations of @Component for more specific use cases, for example, in the persistence, service, and presentation layers, respectively.

Eclipse: failed to create the java virtual machine – message box

Change it to a table-valued function

Please refer to the following link, for example.

Please people don't give up your old habits just yet. There is a large difference in speed between allocating memory once then working with the entries in that array (as of old), and allocating it many times as an array grows (which is inevitably what the system does under the hood with other suggested methods).

None of this matters of course, until you want to do something cool with larger arrays. Then it does.

Seeing as there still seems to be no option in JS at the moment to set the initial capacity of an array, I use the following...

var newArrayWithSize = function(size) {
  this.standard = this.standard||[];
  for (var add = size-this.standard.length; add>0; add--) {
   this.standard.push(undefined);// or whatever
  }
  return this.standard.slice(0,size);
}

There are tradeoffs involved:

• This method takes as long as the others for the first call to the function, but very little time for later calls (unless asking for a bigger array).
• The standard array does permanently reserve as much space as the largest array you have asked for.

But if it fits with what you're doing there can be a payoff. Informal timing puts

for (var n=10000;n>0;n--) {var b = newArrayWithSize(10000);b[0]=0;}

at pretty speedy (about 50ms for the 10000 given that with n=1000000 it took about 5 seconds), and

for (var n=10000;n>0;n--) {
  var b = [];for (var add=10000;add>0;add--) {
    b.push(undefined);
  }
}

at well over a minute (about 90 sec for the 10000 on the same chrome console, or about 2000 times slower). That won't just be the allocation, but also the 10000 pushes, for loop, etc..

Tried this out quickly in the interactive shell:

>>> l = ['a', 'ab', 'abc', 'bac']
>>> [x for x in l if 'ab' in x]
['ab', 'abc']
>>>

Why does this work? Because the in operator is defined for strings to mean: "is substring of".

Also, you might want to consider writing out the loop as opposed to using the list comprehension syntax used above:

l = ['a', 'ab', 'abc', 'bac']
result = []
for s in l:
   if 'ab' in s:
       result.append(s)

The manual page (or the online GNU manual) pretty much explains everything.

find -exec command {} \;

For each result, command {} is executed. All occurences of {} are replaced by the filename. ; is prefixed with a slash to prevent the shell from interpreting it.

find -exec command {} +

Each result is appended to command and executed afterwards. Taking the command length limitations into account, I guess that this command may be executed more times, with the manual page supporting me:

the total number of invocations of the command will be much less than the number of matched files.

Note this quote from the manual page:

The command line is built in much the same way that xargs builds its command lines

That's why no characters are allowed between {} and + except for whitespace. + makes find detect that the arguments should be appended to the command just like xargs.

The solution

Luckily, the GNU implementation of mv can accept the target directory as an argument, with either -t or the longer parameter --target. It's usage will be:

mv -t target file1 file2 ...

Your find command becomes:

find . -type f -iname '*.cpp' -exec mv -t ./test/ {} \+

From the manual page:

-exec command ;

Execute command; true if 0 status is returned. All following arguments to find are taken to be arguments to the command until an argument consisting of `;' is encountered. The string `{}' is replaced by the current file name being processed everywhere it occurs in the arguments to the command, not just in arguments where it is alone, as in some versions of find. Both of these constructions might need to be escaped (with a `\') or quoted to protect them from expansion by the shell. See the EXAMPLES section for examples of the use of the -exec option. The specified command is run once for each matched file. The command is executed in the starting directory. There are unavoidable security problems surrounding use of the -exec action; you should use the -execdir option instead.

-exec command {} +

This variant of the -exec action runs the specified command on the selected files, but the command line is built by appending each selected file name at the end; the total number of invocations of the command will be much less than the number of matched files. The command line is built in much the same way that xargs builds its command lines. Only one instance of `{}' is allowed within the command. The command is executed in the starting directory.

Using UITableViewController

The solution accepted will change the height of the TableViewCell. To fix that, perform following steps:

1. Write code snippet given below in ViewDidLoad method.

   tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

2. Add following method in the TableViewClass.m file.

   - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath 
   {
       return (cell height set on storyboard); 
   }
   

That's it. You can build and run your project.

If you want to collect screen resolution you can run the following code within a WPF window (the window is what the this would refer to):

System.Windows.Media.Matrix m = PresentationSource.FromVisual(this).CompositionTarget.TransformToDevice;
Double dpiX = m.M11 * 96;
Double dpiY = m.M22 * 96;

After run this command:

(aws ecr get-login --no-include-email --region us-west-2)

just run the docker login command from the output

docker login -u AWS -p epJ....

is the way that docker login into ECR

jsFunction is not in good closure. change to:

jsFunction = function(value)
{
    alert(value);
}

and don't use global variables and functions, change it into module

You can modify the codes and be able to save the images in regular interval and do rest of the processing you want.

If I understand correctly, you should be able to do what you want by dropping the foreign key constraint, adding a new one (which will cascade), doing your stuff, and recreating the restricting foreign key constraint.

For example:

testing=# create table a (id integer primary key);
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "a_pkey" for table "a"
CREATE TABLE
testing=# create table b (id integer references a);
CREATE TABLE

-- put some data in the table
testing=# insert into a values(1);
INSERT 0 1
testing=# insert into a values(2);
INSERT 0 1
testing=# insert into b values(2);
INSERT 0 1
testing=# insert into b values(1);
INSERT 0 1

-- restricting works
testing=# delete from a where id=1;
ERROR:  update or delete on table "a" violates foreign key constraint "b_id_fkey" on table "b"
DETAIL:  Key (id)=(1) is still referenced from table "b".

-- find the name of the constraint
testing=# \d b;
       Table "public.b"
 Column |  Type   | Modifiers 
--------+---------+-----------
 id     | integer | 
Foreign-key constraints:
    "b_id_fkey" FOREIGN KEY (id) REFERENCES a(id)

-- drop the constraint
testing=# alter table b drop constraint b_a_id_fkey;
ALTER TABLE

-- create a cascading one
testing=# alter table b add FOREIGN KEY (id) references a(id) on delete cascade; 
ALTER TABLE

testing=# delete from a where id=1;
DELETE 1
testing=# select * from a;
 id 
----
  2
(1 row)

testing=# select * from b;
 id 
----
  2
(1 row)

-- it works, do your stuff.
-- [stuff]

-- recreate the previous state
testing=# \d b;
       Table "public.b"
 Column |  Type   | Modifiers 
--------+---------+-----------
 id     | integer | 
Foreign-key constraints:
    "b_id_fkey" FOREIGN KEY (id) REFERENCES a(id) ON DELETE CASCADE

testing=# alter table b drop constraint b_id_fkey;
ALTER TABLE
testing=# alter table b add FOREIGN KEY (id) references a(id) on delete restrict; 
ALTER TABLE

Of course, you should abstract stuff like that into a procedure, for the sake of your mental health.

Extract all audio tracks / streams

This puts all audio into one file:

ffmpeg -i input.mov -map 0:a -c copy output.mov

• -map 0:a selects all audio streams only. Video and subtitles will be excluded.
• -c copy enables stream copy mode. This copies the audio and does not re-encode it. Remove -c copy if you want the audio to be re-encoded.
• Choose an output format that supports your audio format. See comparison of container formats.

Extract a specific audio track / stream

Example to extract audio stream #4:

ffmpeg -i input.mkv -map 0:a:3 -c copy output.m4a

• -map 0:a:3 selects audio stream #4 only (ffmpeg starts counting from 0).
• -c copy enables stream copy mode. This copies the audio and does not re-encode it. Remove -c copy if you want the audio to be re-encoded.
• Choose an output format that supports your audio format. See comparison of container formats.

Extract and re-encode audio / change format

Similar to the examples above, but without -c copy. Various examples:

ffmpeg -i input.mp4 -map 0:a output.mp3
ffmpeg -i input.mkv -map 0:a output.m4a
ffmpeg -i input.avi -map 0:a -c:a aac output.mka
ffmpeg -i input.mp4 output.wav

Extract all audio streams individually

This input in this example has 4 audio streams. Each audio stream will be output as single, individual files.

ffmpeg -i input.mov -map 0:a:0 output0.wav -map 0:a:1 output1.wav -map 0:a:2 output2.wav -map 0:a:3 output3.wav

Optionally add -c copy before each output file name to enable stream copy mode.

Extract a certain channel

Use the channelsplit filter. Example to get the Front Right (FR) channel from a stereo input:

ffmpeg -i stereo.wav -filter_complex "[0:a]channelsplit=channel_layout=stereo:channels=FR[right]" -map "[right]" front_right.wav

• channel_layout is the channel layout of the input. It is not automatically detected so you must provide the layout name.
• channels lists the channel(s) you want to extract.
• See ffmpeg -layouts for audio channel layout names (for channel_layout) and channel names (for channels).
• Using stream copy mode (-c copy) is not possible to use when filtering, so the audio must be re-encoded.
• See FFmpeg Wiki: Audio Channels for more examples.

What's the difference between -map and -vn?

ffmpeg has a default stream selection behavior that will select 1 stream per stream type (1 video, 1 audio, 1 subtitle, 1 data).

-vn is an old, legacy option. It excludes video from the default stream selection behavior. So audio, subtitles, and data are still automatically selected unless told not to with -an, -sn, or -dn.

-map is more complicated but more flexible and useful. -map disables the default stream selection behavior and ffmpeg will only include what you tell it to with -map option(s). -map can also be used to exclude certain streams or stream types. For example, -map 0 -map -0:v would include all streams except all video.

See FFmpeg Wiki: Map for more examples.

Errors

Invalid audio stream. Exactly one MP3 audio stream is required.

MP3 only supports 1 audio stream. The error means you are trying to put more than 1 audio stream into MP3. It can also mean you are trying to put non-MP3 audio into MP3.

WAVE files have exactly one stream

Similar to above.

Could not find tag for codec in stream #0, codec not currently supported in container

You are trying to put an audio format into an output that does not support it, such as PCM (WAV) into MP4.

Remove -c copy, choose a different output format (change the file name extension), or manually choose the encoder (such as -c:a aac).

See comparison of container formats.

Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

This is a useless, generic error. The actual, informative error should immediately precede this generic error message.

I got this working with out removing any patches. The above patch was not working too. Finally what I did was on the IIS server install the following patch and reset / restart the IIS server. This is not for report manager application. This is for any ASP.NET Web application developed in .net3.5 using VS2008 http://www.microsoft.com/downloads/details.aspx?familyid=6AE0AA19-3E6C-474C-9D57-05B2347456B1&displaylang=en

After you edit /etc/php5/apache2/php.ini be sure to restart apache.

You can do so by running:

sudo service apache2 restart

I see a lot of answers and almost everywhere it's mentioned @Component is for autowiring where component is scanned, and @Bean is exactly declaring that bean to be used differently. Let me show how it's different.

• @Bean

First it's a method level annotation. Second you generally use it to configure beans in Java code (if you are not using xml configuration) and then call it from a class using the ApplicationContext.getBean method. Example:

@Configuration
class MyConfiguration{
    @Bean
    public User getUser() {
        return new User();
    }
}

class User{
}    
        
// Getting Bean 
User user = applicationContext.getBean("getUser");

• @Component

It is the general way to annotate a bean and not a specialized bean. It is a class level annotation and is used to avoid all that configuration stuff through java or xml configuration.

We get something like this.

@Component
class User {
}

// to get Bean
@Autowired
User user;

That's it. It was just introduced to avoid all the configuration steps to instantiate and use that bean.

I know this is old, but I recently faced the same issue and I managed to pick the element by accessing only the attribute like this: document.querySelector('[name="your-selector-name-here"]');

Just in case anyone would ever need this :)

If you want to work with python 3, it's very simple:

print("If there was a birth every 7 second, there would be %d births." % (births))

First you check your user agent OS Linux or windows or another. Then Your OS Windows Then this code use:

public function win_os(){ 
    ob_start();
    system('ipconfig-a');
    $mycom=ob_get_contents(); // Capture the output into a variable
    ob_clean(); // Clean (erase) the output buffer
    $findme = "Physical";
    $pmac = strpos($mycom, $findme); // Find the position of Physical text
    $mac=substr($mycom,($pmac+36),17); // Get Physical Address

    return $mac;
   }

And your OS Linux Ubuntu or Linux then this code use:

public function unix_os(){
    ob_start();
    system('ifconfig -a');
    $mycom = ob_get_contents(); // Capture the output into a variable
    ob_clean(); // Clean (erase) the output buffer
    $findme = "Physical";
    //Find the position of Physical text 
    $pmac = strpos($mycom, $findme); 
    $mac = substr($mycom, ($pmac + 37), 18);

    return $mac;
    }

This code may be work OS X.

Just a note for php developers (I lack the necessary stackoverflow points to post this as a comment) ... the automagic (and silent) conversion to TINYINT means that php retrieves a value from a "BOOLEAN" column as a "0" or "1", not the expected (by me) true/false.

A developer who is looking at the SQL used to create a table and sees something like: "some_boolean BOOLEAN NOT NULL DEFAULT FALSE," might reasonably expect to see true/false results when a row containing that column is retrieved. Instead (at least in my version of PHP), the result will be "0" or "1" (yes, a string "0" or string "1", not an int 0/1, thank you php).

It's a nit, but enough to cause unit tests to fail.

The CSS by Paulius Marciukaitis worked nicely for my Genesis theme, here's what how I further modified it for my requirement:

@media only screen and (max-width: 480px) {
.entry {
background-color: #fff;
margin-bottom: 0;
padding: 10px 8px;

}

Docker container installation for php:XXX Debian based images:

RUN apt-get update && apt-get install -y --no-install-recommends libmagickwand-dev
RUN pecl install imagick && docker-php-ext-enable imagick
RUN apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* || true

Just because I did not see it mentioned.

If 2016+, here is yet another option to dynamically unpivot data without actually using Dynamic SQL.

Example

Declare @YourTable Table ([ID] varchar(50),[Col1] varchar(50),[Col2] varchar(50))
Insert Into @YourTable Values 
 (1,'A','B')
,(2,'R','C')
,(3,'X','D')

Select A.[ID]
      ,Item  = B.[Key]
      ,Value = B.[Value]
 From  @YourTable A
 Cross Apply ( Select * 
                From  OpenJson((Select A.* For JSON Path,Without_Array_Wrapper )) 
                Where [Key] not in ('ID','Other','Columns','ToExclude')
             ) B

Returns

ID  Item    Value
1   Col1    A
1   Col2    B
2   Col1    R
2   Col2    C
3   Col1    X
3   Col2    D

Single Line Python Program
The best way I have found is to write a single line program that downloads and runs the official get-pip script. See below for the code.

The official docs recommend using curl to download the get-pip script, but since I work on windows and don't have curl installed I prefer using python itself to download and run the script.

Here is the single line program that can be run via the command line using Python 3:

python -c "import urllib.request; exec(urllib.request.urlopen('https://bootstrap.pypa.io/get-pip.py').read())"

This line gets the official "get-pip.py" script as per the installation notes and executes the script with the "exec" command.

For Python2 you would replace "urllib.request" with "urllib2":

python -c "import urllib2; exec(urllib2.urlopen('https://bootstrap.pypa.io/get-pip.py').read())"

Precautions
It's worth noting that running any python script blindly is inherently dangerous. For this reason, the official instructions recommend downloading the script and inspecting it before running.

That said, many people don't actually inspect the code and just run it. This one-line program makes that easier.

String result = String.format("%0" + messageDigest.length + "s", hexString.toString())

That's the shortest solution given what you already have. If you could convert the byte array to a numeric value, String.format can convert it to a hex string at the same time.

I happen to miss spaces in my query and this error comes.

Ex: $sql= "SELECT * FROM";
$sql .= "table1";

Though the example might look simple, when coding complex queries, the probability for this error is high. I was missing space before word "table1".

I think there will be different ways to select a Date for different Date picker formats. For a Date Picker where you need to select a year and month from a dropdown and then pick/click a Date, I wrote the following code.

private void setupDate(WebDriver driver, String csvRow) throws Exception {
    String date[] = (csvRow).split("-");
    driver.findElement(By.id("flddateanchor")).click();
    new Select(driver.findElement(By
            .cssSelector("select.ui-datepicker-year")))
            .selectByVisibleText(date[0]);
    Thread.sleep(1000);
    new Select(driver.findElement(By
            .cssSelector("select.ui-datepicker-month")))
            .selectByVisibleText(date[1]);
    Thread.sleep(1000);
    driver.findElement(By.linkText(date[2])).click();
    Thread.sleep(1000);
}

I got the cssSelector part by the Selenium Firefox IDE. Also, my Date(csvRow) is in (2015-03-31) format.

Hope it helps.

I don't know if this is really any different, but rather than iterate over the query cursor, you could do something like this:

query.exec(function (err, results){
  if (err) res.writeHead(500, err.message)
  else if (!results.length) res.writeHead(404);
  else {
    res.writeHead(200, { 'Content-Type': 'application/json' });
    res.write(JSON.stringify(results.map(function (msg){ return {msgId: msg.fileName}; })));
  }
  res.end();
});

Set it with a px value. Changing the code like below should work

el.css('marginLeft', mrg + 'px');

If you are using Node/Chrome. The following snippet will get you extension which meets the following requirements.

• err instanceof Error
• err instanceof CustomErrorType
• console.log() returns [CustomErrorType] when created with a message
• console.log() returns [CustomErrorType: message] when created without a message
• throw/stack provides the information at the point the error was created.
• Works optimally in Node.JS, and Chrome.
• Will pass instanceof checks in Chrome, Safari, Firefox and IE 8+, but will not have a valid stack outside of Chrome/Safari. I'm OK with that because I can debug in chrome, but code which requires specific error types will still function cross browser. If you need Node only you can easily remove the if statements and you're good to go.

Snippet

var CustomErrorType = function(message) {
    if (Object.defineProperty) {
        Object.defineProperty(this, "message", {
            value : message || "",
            enumerable : false
        });
    } else {
        this.message = message;
    }

    if (Error.captureStackTrace) {
        Error.captureStackTrace(this, CustomErrorType);
    }
}

CustomErrorType.prototype = new Error();
CustomErrorType.prototype.name = "CustomErrorType";

Usage

var err = new CustomErrorType("foo");

Output

var err = new CustomErrorType("foo");
console.log(err);
console.log(err.stack);

You need to use parentheses: myList.insert([1, 2, 3]). When you leave out the parentheses, python thinks you are trying to access myList.insert at position 1, 2, 3, because that's what brackets are used for when they are right next to a variable.

What if you dynamically wrote a < script > section on your page (with your dynamic rules) and then used jQuerys .addClass( class ) to add those dynamically created rules?

I have not tried this, just offering a theory that might work.

Here's a revised version of your code which still works plus it illustrates how to raise a ValueError the way you want. By-the-way, I think find_last(), find_last_index(), or something simlar would be a more descriptive name for this function. Adding to the possible confusion is the fact that Python already has a container object method named __contains__() that does something a little different, membership-testing-wise.

def contains(char_string, char):
    largest_index = -1
    for i, ch in enumerate(char_string):
        if ch == char:
            largest_index = i
    if largest_index > -1:  # any found?
        return largest_index  # return index of last one
    else:
        raise ValueError('could not find {!r} in {!r}'.format(char, char_string))

print(contains('mississippi', 's'))  # -> 6
print(contains('bababa', 'k'))  # ->

Traceback (most recent call last):
  File "how-to-raise-a-valueerror.py", line 15, in <module>
    print(contains('bababa', 'k'))
  File "how-to-raise-a-valueerror.py", line 12, in contains
    raise ValueError('could not find {} in {}'.format(char, char_string))
ValueError: could not find 'k' in 'bababa'

Update — A substantially simpler way

Wow! Here's a much more concise version—essentially a one-liner—that is also likely faster because it reverses (via [::-1]) the string before doing a forward search through it for the first matching character and it does so using the fast built-in string index() method. With respect to your actual question, a nice little bonus convenience that comes with using index() is that it already raises a ValueError when the character substring isn't found, so nothing additional is required to make that happen.

Here it is along with a quick unit test:

def contains(char_string, char):
    #  Ending - 1 adjusts returned index to account for searching in reverse.
    return len(char_string) - char_string[::-1].index(char) - 1

print(contains('mississippi', 's'))  # -> 6
print(contains('bababa', 'k'))  # ->

Traceback (most recent call last):
  File "better-way-to-raise-a-valueerror.py", line 9, in <module>
    print(contains('bababa', 'k'))

    return len(char_string) - char_string[::-1].index(char) - 1

First is understanding that RFID is very generic term. NFC is subset of RFID technology. NFC is used for prox card, credit cards, tap and go payment system. Your phones can read and emulate NFC (Apple pay, Google pay, etc.), if they support NFC. NFC is very short distance and low power - which is why you see tap and go type usage.

The more common RFID are the tags you see here and there. They come in a wide ranges of styles, uses and frequency.

HF - high frequency tags are what they use for "chipping" animals - cattle, dogs, cats. Read range is about 12 inches and requires an external antenna that is powered the bigger the antenna the more power it needs and the further it can read.

UFH tags look similar to HF tags but have a read range of several feet.

Also HF tags come single read and multi read. UFH is exclusviely multi read.

Mutiread means when a reader is active, you can litterally read about 1700 tags in under 10 seconds.

But this is a function of the size of the antenna and how much power you can push through the reader.

As to the direct question about Android and RFID - the best way to go is to get an external handheld reader that connects to your mobile device via Bluetooth. Bluetooth libraries exist for all mobile devices - Android, Apple, Windows. From there its just a matter of the manufacturer documentation about how to open a socket to the reader and how to decode the serial information.

The TSL line of readers is very popular because you don't have to deal with reading bytes and all that low level serial jazz that other manufactures do. They have a nice set of commands that are easy to use to control the reader.

Other manufactures are basic in that you open a serial socket and then read the output like you would see in terminal app like PuTTY.

I test this code and

$db=new PDO('mysql:host=localhost;dbname=cwDB','root','',
array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));
$sql="select * from products  ";
$stmt=$db->prepare($sql);
$stmt->execute();
while($result=$stmt->fetch(PDO::FETCH_ASSOC)){                  
    $id=$result['id'];
}

You can use Git GUI on Windows, see instructions:

1. Open the Git Gui (After installing the Git on your computer).

2. Clone your repository to your local hard drive:

3. After cloning, GUI opens, choose: "Rescan" for changes that you made:

4. You will notice the scanned files:

5. Click on "Stage Changed":

6. Approve and click "Commit":

7. Click on "Push":

8. Click on "Push":

9. Wait for the files to upload to git:

If you are new to React JS and using create-react-app cli command to create the application, then run the following NPM command to include the latest version of font-awesome.

npm install --save font-awesome

import font-awesome to your index.js file. Just add below line to your index.js file

import '../node_modules/font-awesome/css/font-awesome.min.css'; 

or

import 'font-awesome/css/font-awesome.min.css';

Don't forget to use className as attribute

 render: function() {
    return <div><i className="fa fa-spinner fa-spin">no spinner but why</i></div>;
}

This will translate to a where in clause in Linq to SQL...

var myInClause = new string[] {"One", "Two", "Three"};

var results = from x in MyTable
              where myInClause.Contains(x.SomeColumn)
              select x;
// OR
var results = MyTable.Where(x => myInClause.Contains(x.SomeColumn));

In the case of your query, you could do something like this...

var results = from states in _objectdatasource.StateList()
              where listofcountrycodes.Contains(states.CountryCode)
              select new State
              {
                  StateName = states.StateName
              };
// OR
var results = _objectdatasource.StateList()
                  .Where(s => listofcountrycodes.Contains(s.CountryCode))
                  .Select(s => new State { StateName = s.StateName});

Exact same thing, just omit the -c option. Apache's docs on it here.

htpasswd /etc/apache2/.htpasswd newuser

Also, htpasswd typically isn't run as root. It's typically owned by either the web server, or the owner of the files being served. If you're using root to edit it instead of logging in as one of those users, that's acceptable (I suppose), but you'll want to be careful to make sure you don't accidentally create a file as root (and thus have root own it and no one else be able to edit it).

Try this:

cd 
source .bash_profile

This is what worked for me...

import cv2
import numpy as np

#Created an image (really an ndarray) with three channels 
new_image = np.ndarray((3, num_rows, num_cols), dtype=int)

#Did manipulations for my project where my array values went way over 255
#Eventually returned numbers to between 0 and 255

#Converted the datatype to np.uint8
new_image = new_image.astype(np.uint8)

#Separated the channels in my new image
new_image_red, new_image_green, new_image_blue = new_image

#Stacked the channels
new_rgb = np.dstack([new_image_red, new_image_green, new_image_blue])

#Displayed the image
cv2.imshow("WindowNameHere", new_rgbrgb)
cv2.waitKey(0)

Set the class .fill to height: 100%

.fill { 
    min-height: 100%;
    height: 100%;
}

JSFiddle

(I put a red background for #map so you can see it takes up 100% height)

Well, I don't have a function in python but I have a function in C which you can easily convert to python, in the below c function extended euclidian algorithm is used to calculate inverse mod.

int imod(int a,int n){
int c,i=1;
while(1){
    c = n * i + 1;
    if(c%a==0){
        c = c/a;
        break;
    }
    i++;
}
return c;}

Python Function

def imod(a,n):
  i=1
  while True:
    c = n * i + 1;
    if(c%a==0):
      c = c/a
      break;
    i = i+1

  return c

Reference to the above C function is taken from the following link C program to find Modular Multiplicative Inverse of two Relatively Prime Numbers

Datalist includes autocomplete and suggestions natively, it can also allow a user to enter a value that is not defined in the suggestions.

Select only gives you pre-defined options the user has to select from

var div = document.createElement('div');
div.setAttribute('style', 'width:330px; float:left');
div.setAttribute('class', 'well');
var label = document.createElement('label');
label.innerHTML = 'YOUR TEXT HERE';
div.appendChild(label);

Why does everyone like to list out source files? A simple find command can take care of that easily.

Here's an example of a dirt simple C++ Makefile. Just drop it in a directory containing .C files and then type make...

appname := myapp

CXX := clang++
CXXFLAGS := -std=c++11

srcfiles := $(shell find . -name "*.C")
objects  := $(patsubst %.C, %.o, $(srcfiles))

all: $(appname)

$(appname): $(objects)
    $(CXX) $(CXXFLAGS) $(LDFLAGS) -o $(appname) $(objects) $(LDLIBS)

depend: .depend

.depend: $(srcfiles)
    rm -f ./.depend
    $(CXX) $(CXXFLAGS) -MM $^>>./.depend;

clean:
    rm -f $(objects)

dist-clean: clean
    rm -f *~ .depend

include .depend

Most of answers are correct only want to add one point here

In Spark 2.0 the two APIs (DataFrame +DataSet) will be unified together into a single API.

"Unifying DataFrame and Dataset: In Scala and Java, DataFrame and Dataset have been unified, i.e. DataFrame is just a type alias for Dataset of Row. In Python and R, given the lack of type safety, DataFrame is the main programming interface."

Datasets are similar to RDDs, however, instead of using Java serialization or Kryo they use a specialized Encoder to serialize the objects for processing or transmitting over the network.

Spark SQL supports two different methods for converting existing RDDs into Datasets. The first method uses reflection to infer the schema of an RDD that contains specific types of objects. This reflection based approach leads to more concise code and works well when you already know the schema while writing your Spark application.

The second method for creating Datasets is through a programmatic interface that allows you to construct a schema and then apply it to an existing RDD. While this method is more verbose, it allows you to construct Datasets when the columns and their types are not known until runtime.

Here you can find RDD tof Data frame conversation answer

How to convert rdd object to dataframe in spark

Change this:

SET @ActualWeightDIMS= @Actual_Dims_Lenght + 'x' + 
    @Actual_Dims_Width + 'x' + @Actual_Dims_Height;

To this:

SET @ActualWeightDIMS= CAST(@Actual_Dims_Lenght as varchar(3)) + 'x' + 
    CAST(@Actual_Dims_Width as varchar(3)) + 'x' + 
    CAST(@Actual_Dims_Height as varchar(3));

Change this:

SET @ActualWeightDIMS = @ActualWeight;

To this:

SET @ActualWeightDIMS = CAST(@ActualWeight as varchar(50));

You need to use CAST. Learn all about CAST and CONVERT here, because data types are important!

Closing IIS Express

By default Visual Studio places the IISExpress icon in your system tray at the lower right hand side of your screen, by the clock. You can right click it and choose exit. If you don't see the icon, try clicking the small arrow to view the full list of icons in the system tray.

then right click and choose Exit:

Changing the Port

Another option is to change the port by modifying the project properties. You'll need to do this for each web project in your solution.

1. Visual Studio > Solution Explorer
2. Right click the web project and choose Properties
3. Go to the Web tab
4. In the 'Servers' section, change the port in the Project URL box
5. Repeat for each web project in the solution

If All Else Fails

If that doesn't work, you can try to bring up Task Manager and close the IIS Express System Tray (32 bit) process and IIS Express Worker Process (32 bit).

If it still doesn't work, as ni5ni6 pointed out, there is a 'Web Deployment Agent Service' running on the port 80. Use this article to track down which process uses it, and turn it off:

https://sites.google.com/site/anashkb/port-80-in-use

As you want to exclude both words, you need a conjuction:

^/(?!ignoreme$)(?!ignoreme2$)[a-z0-9]+$

Now both conditions must be true (neither ignoreme nor ignoreme2 is allowed) to have a match.

Open base_facebook.php Add Access_token at function getLoginUrl()

array_merge(array(
                  'access_token' => $this->getAccessToken(),
                  'client_id' => $this->getAppId(),
                  'redirect_uri' => $currentUrl, // possibly overwritten
                  'state' => $this->state),
             $params);

and Use scope for Email Permission

if ($user) {
   echo $logoutUrl = $facebook->getLogoutUrl();
} else {
   echo $loginUrl = $facebook->getLoginUrl(array('scope' => 'email,read_stream'));
}

I resolved this by clearing App Data.

Cypress documentation admits that App Data can get corrupted:

Cypress maintains some local application data in order to save user preferences and more quickly start up. Sometimes this data can become corrupted. You may fix an issue you have by clearing this app data.

1. Open Cypress via cypress open
2. Go to File -> View App Data
3. This will take you to the directory in your file system where your App Data is stored. If you cannot open Cypress, search your file system for a directory named cy whose content should look something like this:

       production
            all.log
            browsers
            bundles
            cache
            projects
            proxy
            state.json

4. Delete everything in the cy folder
5. Close Cypress and open it up again

Source: https://docs.cypress.io/guides/references/troubleshooting.html#To-clear-App-Data

When the session expires the data is no longer present, so something like

if (!isset($_SESSION['id'])) {
    header("Location: destination.php");
    exit;
}

will redirect whenever the session is no longer active.

You can set how long the session cookie is alive using session.cookie_lifetime

ini_set("session.cookie_lifetime","3600"); //an hour

EDIT: If you are timing sessions out due to security concern (instead of convenience,) use the accepted answer, as the comments below show, this is controlled by the client and thus not secure. I never thought of this as a security measure.

I was facing the same issue. I was trying to build linux application for Cyclone V FPGA-SoC. I faced the problem as below:

Error: <application_name> uses VFP register arguments, main.o does not

I was using the toolchain arm-linux-gnueabihf-g++ provided by embedded software design tool of altera.

It is solved by exporting: mfloat-abi=hard to flags, then arm-linux-gnueabihf-g++ compiles without errors. Also include the flags in both CC & LD.

What you could also do is put a .htaccess file containing

RewriteEngine Off

In the folders you want to exclude from being rewritten (by the rules in a .htaccess file that's higher up in the tree). Simple but effective.

Set variable "a" to some value like this,

a=0;

Declaring and initialzing are both different.

Good Luck

This is what I did, I hope it helps.

def find_pos(chaine,x):

    for i in range(len(chaine)):
        if chaine[i] ==x :
            return 'yes',i 
    return 'no'

You can set the value of document.location.href for this purpose. It points to the current URL. jQuery is not required to do this.

In my case, we have time series from different devices but some devices could not send any value during some period. So we should create NA values for every device and time period and after that do fillna.

df = pd.DataFrame([["device1", 1, 'first val of device1'], ["device2", 2, 'first val of device2'], ["device3", 3, 'first val of device3']])
df.pivot(index=1, columns=0, values=2).fillna(method='ffill').unstack().reset_index(name='value')

Result:

        0   1   value
0   device1     1   first val of device1
1   device1     2   first val of device1
2   device1     3   first val of device1
3   device2     1   None
4   device2     2   first val of device2
5   device2     3   first val of device2
6   device3     1   None
7   device3     2   None
8   device3     3   first val of device3

Once you've done this

group p by p.SomeId into pg  

you no longer have access to the range variables used in the initial from. That is, you can no longer talk about p or bp, you can only talk about pg.

Now, pg is a group and so contains more than one product. All the products in a given pg group have the same SomeId (since that's what you grouped by), but I don't know if that means they all have the same BaseProductId.

To get a base product name, you have to pick a particular product in the pg group (As you are doing with SomeId and CountryCode), and then join to BaseProducts.

var result = from p in Products                         
 group p by p.SomeId into pg                         
 // join *after* group
 join bp in BaseProducts on pg.FirstOrDefault().BaseProductId equals bp.Id         
 select new ProductPriceMinMax { 
       SomeId = pg.FirstOrDefault().SomeId, 
       CountryCode = pg.FirstOrDefault().CountryCode, 
       MinPrice = pg.Min(m => m.Price), 
       MaxPrice = pg.Max(m => m.Price),
       BaseProductName = bp.Name  // now there is a 'bp' in scope
 };

That said, this looks pretty unusual and I think you should step back and consider what you are actually trying to retrieve.

Notice that you're using Observable#map to convert the raw Response object your base Observable emits to a parsed representation of the JSON response.

If I understood you correctly, you want to map again. But this time, converting that raw JSON to instances of your Model. So you would do something like:

http.get('api/people.json')
  .map(res => res.json())
  .map(peopleData => peopleData.map(personData => new Person(personData)))

So, you started with an Observable that emits a Response object, turned that into an observable that emits an object of the parsed JSON of that response, and then turned that into yet another observable that turned that raw JSON into an array of your models.

For Express.js you want to do req.params:

app.get('/user/:id', function(req, res) {
  res.send('user' + req.params.id);    
});

For my example :first 'MainActivity' implements 'View.OnClickListener' than start the code ....

@Override

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    init();}


public void init(){

    foryou = (Button) this.findViewById(R.id.btn_foryou);
    following = (Button) findViewById(R.id.btn_following);
    popular = (Button) findViewById(R.id.btn_popular);
    watching = (Button) findViewById(R.id.btn_continuewatching);
    mProgress = (ProgressBar) findViewById(R.id.pb);

    foryou.setOnClickListener(this);
    following.setOnClickListener(this);
    popular.setOnClickListener(this);
    watching.setOnClickListener(this);
    mProgress.setOnClickListener(this);
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.btn_foryou:
            foryou.setPaintFlags(foryou.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_following:
            following.setPaintFlags(following.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_popular:
            popular.setPaintFlags(popular.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_continuewatching:
            watching.setPaintFlags(watching.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_5:
            // foryou.setPaintFlags(foryou.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        default:
            foryou.setPaintFlags(foryou.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

    }
}

Oh, I just found that command on PostgreSQL forum:

SELECT * FROM pg_stat_activity;

Use substr($path, strrpos($path,'.')+1);. It is the fastest method of all compares.

@Kurt Zhong already answered.

Let's check the comparative result here: https://eval.in/661574

It's very useful for beginners to know why join is a string method.

It's very strange at the beginning, but very useful after this.

The result of join is always a string, but the object to be joined can be of many types (generators, list, tuples, etc).

.join is faster because it allocates memory only once. Better than classical concatenation (see, extended explanation).

Once you learn it, it's very comfortable and you can do tricks like this to add parentheses.

>>> ",".join("12345").join(("(",")"))
Out:
'(1,2,3,4,5)'

>>> list = ["(",")"]
>>> ",".join("12345").join(list)
Out:
'(1,2,3,4,5)'

I liked PostMan, it was the main reason why I kept using Chrome, now I'm good with HttpRequester

https://addons.mozilla.org/En-us/firefox/addon/httprequester/?src=search

Here are the steps I followed:

1. In bash, check in which directory you are by using the command:

   $ pwd
   

2. copy the URL of the directory you want to go like after using the first command (PWD) I got:

   $  /c/Users/yourUsername
   

3. Now I want to change this to the directory of c drive and folder MyPictures. To do that, I will go the directory of MyPictures, copy the URL, and paste it in the Git bash. However, before that:

   

   C:\MyPicture becomes $ cd /C/MyPicture (backslashes are replaced with slashes)

4. if the folder name is having some spaces like (my program) then you need to enclose it in double quotes like:

   $ cd "C:\Program Files"
   

5. Remember to change directory you just need to copy the requiredUrl and paste that in bash with double-quotes like:

   cd "required URL"
   

Note: URL required with slashes.

here's non-paste methods

awk

awk 'BEGIN {OFS=" "}{
  getline line < "file2"
  print $0,line
} ' file1

Bash

exec 6<"file2"
while read -r line
do
    read -r f2line <&6
    echo "${line}${f2line}"
done <"file1"
exec 6<&-

My situation is probably a little different. I am dynamically changing the src of an image via javascript and needed to ensure that the new image is sized proportionally to fit a fixed container (in a photo gallery). I initially just removed the width and height attributes of the image after it is loaded (via the image's load event) and reset these after calculating the preferred dimensions. However, that does not work in Safari and possibly IE (I have not tested it in IE thoroughly, but the image doesn't even show, so...).

Anyway, Safari keeps the dimensions of the previous image so the dimensions are always one image behind. I assume that this has something to do with cache. So the simplest solution is to just clone the image and add it to the DOM (it is important that it be added to the DOM the get the with and height). Give the image a visibility value of hidden (do not use display none because it will not work). After you get the dimensions remove the clone.

Here is my code using jQuery:

// Hack for Safari and others
// clone the image and add it to the DOM
// to get the actual width and height
// of the newly loaded image

var cloned, 
    o_width, 
    o_height, 
    src = 'my_image.jpg', 
    img = [some existing image object];

$(img)
.load(function()
{
    $(this).removeAttr('height').removeAttr('width');
    cloned = $(this).clone().css({visibility:'hidden'});
    $('body').append(cloned);
    o_width = cloned.get(0).width; // I prefer to use native javascript for this
    o_height = cloned.get(0).height; // I prefer to use native javascript for this
    cloned.remove();
    $(this).attr({width:o_width, height:o_height});
})
.attr(src:src);

This solution works in any case.

Not sure what you table structure is like but see below.

public NamePriceModel[] AllProducts()
{
    try
    {
        using (UserDataDataContext db = new UserDataDataContext())
        {
            return db.mrobProducts
                .Where(x => x.Status == 1)
                .Select(x => new NamePriceModel { 
                    Name = x.Name, 
                    Id = x.Id, 
                    Price = x.Price
                })
                .OrderBy(x => x.Id)
                .ToArray();
         }
     }
     catch
     {
         return null;
     }
 }

This would return an array of type anonymous with the members you require.

Update:

Create a new class.

public class NamePriceModel 
{
    public string Name {get; set;}
    public decimal? Price {get; set;}
    public int Id {get; set;}
}

I've modified the query above to return this as well and you should change your method from returning string[] to returning NamePriceModel[].

you can convert it into date format by-

new_date<- as.Date(old_date, "%m/%d/%Y")} 

from new_date, you can get the month by strftime()

month<- strftime(new_date, "%m")

old_date<- "01/01/1979"

You can try loading the file into a firefox window then go to View - Character Encoding. There should be a check mark next to the file's encoding type.

& is always evaluated in a string context, while + may not concatenate if one of the operands is no string:

"1" + "2" => "12"
"1" + 2   => 3
1 + "2"   => 3
"a" + 2   => type mismatch

This is simply a subtle source of potential bugs and therefore should be avoided. & always means "string concatenation", even if its arguments are non-strings:

"1" & "2" => "12"
"1" &  2  => "12"
 1  & "2" => "12"
 1  &  2  => "12"
"a" &  2  => "a2"

ForEach Loop processes each ZIP file located within the $filepath variable

    foreach($file in $filepath)
    {
        $zip = $shell.NameSpace($file.FullName)
        foreach($item in $zip.items())
        {
            $shell.Namespace($file.DirectoryName).copyhere($item)
        }
        Remove-Item $file.FullName
    }

int i = 25;
NSString *myString = [NSString stringWithFormat:@"%d",i];

This is one of many ways.

Your jQuery code works perfectly. The hidden field is being updated.

You just need

.parent-div { text-align: center }

Given that you added notepad++.exe to your PATH variable, it's extra simple. Create a file in your System32 folder called np.bat with the following code:

@echo off
call notepad++.exe %*

The %* passes along all arguments you give the np command to the notepad++.exe command.

EDIT: You will need admin access to save files to the System32 folder, which was a bit wonky for me. I just created the file somewhere else and moved it to System32 manually.

You can execute a function defined in a DLL file by using the rundll command. You can explore the functions available by using Dependency Walker.

It seem like your Resort method doesn't declare a compareTo method. This method typically belongs to the Comparable interface. Make sure your class implements it.

Additionally, the compareTo method is typically implemented as accepting an argument of the same type as the object the method gets invoked on. As such, you shouldn't be passing a String argument, but rather a Resort.

Alternatively, you can compare the names of the resorts. For example

if (resortList[mid].getResortName().compareTo(resortName)>0)  

Use urllib2 and create a Request object which you then hand to urlopen. http://docs.python.org/library/urllib2.html

I dont really use the "old" urllib anymore.

req = urllib2.Request("http://google.com", None, {'User-agent' : 'Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5'})
response = urllib2.urlopen(req).read()

EncloseJS.

You get a fully functional binary without sources.

Native modules also supported. (must be placed in the same folder)

JavaScript code is transformed into native code at compile-time using V8 internal compiler. Hence, your sources are not required to execute the binary, and they are not packaged.

Perfectly optimized native code can be generated only at run-time based on the client's machine. Without that info EncloseJS can generate only "unoptimized" code. It runs about 2x slower than NodeJS.

Also, node.js runtime code is put inside the executable (along with your code) to support node API for your application at run-time.

Use cases:

• Make a commercial version of your application without sources.
• Make a demo/evaluation/trial version of your app without sources.
• Make some kind of self-extracting archive or installer.
• Make a closed source GUI application using node-thrust.
• No need to install node and npm to deploy the compiled application.
• No need to download hundreds of files via npm install to deploy your application. Deploy it as a single independent file.
• Put your assets inside the executable to make it even more portable. Test your app against new node version without installing it.

Assuming that this is .d, you can write

$(this).closest('.a');

The closest method returns the innermost parent of your element that matches the selector.

If you are using Eloquent the best solution is:

public function getFormattedPriceAttribute()
{
    return number_format($this->attributes['price'], 2);
}

So now you must append formattedPrice in your model and you can use both, price (at its original state) and formattedPrice.

Here's some code that I use. I found that if I set any cookie from my site, then cookies magically work in the iframe from then on.

http://developsocialapps.com/foundations-of-a-facebook-app-framework/

 if (isset($_GET['setdefaultcookie'])) {
        // top level page, set default cookie then redirect back to canvas page
        setcookie ('default',"1",0,"/");
        $url = substr($_SERVER['REQUEST_URI'],strrpos($_SERVER['REQUEST_URI'],"/")+1);
        $url = str_replace("setdefaultcookie","defaultcookieset",$url);
        $url = $facebookapp->getCanvasUrl($url);
        echo "<html>\n<body>\n<script>\ntop.location.href='".$url."';\n</script></body></html>";
        exit();
    } else if ((!isset($_COOKIE['default'])) && (!isset($_GET['defaultcookieset']))) {
        // no default cookie, so we need to redirect to top level and set
        $url = $_SERVER['REQUEST_URI'];
        if (strpos($url,"?") === false) $url .= "?";
        else $url .= "&";
        $url .= "setdefaultcookie=1";
        echo "<html>\n<body>\n<script>\ntop.location.href='".$url."';\n</script></body></html>";
        exit();
    }

You can use the following solution to solve your problem:

$mac='UNKNOWN';
foreach(explode("\n",str_replace(' ','',trim(`getmac`,"\n"))) as $i)
if(strpos($i,'Tcpip')>-1){$mac=substr($i,0,17);break;}
echo $mac;

OAuth is a protocol with which a 3-party app can access your data stored in another website without your account and password. For a more official definition, refer to the Wiki or specification.

Here is a use case demo:

1. I login to LinkedIn and want to connect some friends who are in my Gmail contacts. LinkedIn supports this. It will request a secure resource (my gmail contact list) from gmail. So I click this button:
   

2. A web page pops up, and it shows the Gmail login page, when I enter my account and password:
   

3. Gmail then shows a consent page where I click "Accept":

4. Now LinkedIn can access my contacts in Gmail:

Below is a flowchart of the example above:

Step 1: LinkedIn requests a token from Gmail's Authorization Server.

Step 2: The Gmail authorization server authenticates the resource owner and shows the user the consent page. (the user needs to login to Gmail if they are not already logged-in)

Step 3: User grants the request for LinkedIn to access the Gmail data.

Step 4: the Gmail authorization server responds back with an access token.

Step 5: LinkedIn calls the Gmail API with this access token.

Step 6: The Gmail resource server returns your contacts if the access token is valid. (The token will be verified by the Gmail resource server)

You can get more from details about OAuth here.

Late answer, but I figured it's worth keeping this updated. Expanding on Andrea Turri answer to reflect updated jQuery API and .success/.error deprecated methods.

As of jQuery 1.8.* the preferred way of doing this is to use .done() and .fail(). Jquery Docs

e.g.

$('#my_get_related_keywords').click(function() {

    var ajaxRequest = $.ajax({
        type: "POST",
        url: "HERE PUT THE PATH OF YOUR SERVICE OR PAGE",
        data: '{"HERE YOU CAN PUT DATA TO PASS AT THE SERVICE"}',
        contentType: "application/json; charset=utf-8",
        dataType: "json"});

    //When the request successfully finished, execute passed in function
    ajaxRequest.done(function(msg){
           //do something
    });

    //When the request failed, execute the passed in function
    ajaxRequest.fail(function(jqXHR, status){
        //do something else
    });
});

All the other responses I see are fine, but C# has support for named groups!

I'd use the following code:

const string input = "Lorem ipsum dolor sit %download%#456 amet, consectetur adipiscing %download%#3434 elit. Duis non nunc nec mauris feugiat porttitor. Sed tincidunt blandit dui a viverra%download%#298. Aenean dapibus nisl %download%#893434 id nibh auctor vel tempor velit blandit.";

static void Main(string[] args)
{
    Regex expression = new Regex(@"%download%#(?<Identifier>[0-9]*)");
    var results = expression.Matches(input);
    foreach (Match match in results)
    {
        Console.WriteLine(match.Groups["Identifier"].Value);
    }
}

The code that reads: (?<Identifier>[0-9]*) specifies that [0-9]*'s results will be part of a named group that we index as above: match.Groups["Identifier"].Value

The isdigit method of the str type returns True iff the given string is nothing but one or more digits. If it's not, you know the string should be treated as just a string.

Yes , deleteBy method is supported To use it you need to annotate method with @Transactional

You can use following code snippet for get the HttpClient instance without ssl certification checking.

private HttpClient getSSLHttpClient() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {

        LogLoader.serverLog.trace("In getSSLHttpClient()");

        SSLContext context = SSLContext.getInstance("SSL");

        TrustManager tm = new X509TrustManager() {
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };

        context.init(null, new TrustManager[] { tm }, null);

        HttpClientBuilder builder = HttpClientBuilder.create();
        SSLConnectionSocketFactory sslConnectionFactory = new SSLConnectionSocketFactory(context);
        builder.setSSLSocketFactory(sslConnectionFactory);

        PlainConnectionSocketFactory plainConnectionSocketFactory = new PlainConnectionSocketFactory();
        Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
                .register("https", sslConnectionFactory).register("http", plainConnectionSocketFactory).build();

        PoolingHttpClientConnectionManager ccm = new PoolingHttpClientConnectionManager(registry);
        ccm.setMaxTotal(BaseConstant.CONNECTION_POOL_SIZE);
        ccm.setDefaultMaxPerRoute(BaseConstant.CONNECTION_POOL_SIZE);
        builder.setConnectionManager((HttpClientConnectionManager) ccm);

        builder.disableRedirectHandling();

        LogLoader.serverLog.trace("Out getSSLHttpClient()");

        return builder.build();
    }

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

I always just convert a matrix:

x <- as.data.frame(matrix(nrow = 100, ncol = 10))

Simple answer : free(testPerson) is enough .

Remember you can use free() only when you have allocated memory using malloc, calloc or realloc.

In your case you have only malloced memory for testPerson so freeing that is sufficient.

If you have used char * firstname , *last surName then in that case to store name you must have allocated the memory and that's why you had to free each member individually.

Here is also a point it should be in the reverse order; that means, the memory allocated for elements is done later so free() it first then free the pointer to object.

Freeing each element you can see the demo shown below:

typedef struct Person
{
char * firstname , *last surName;
}Person;
Person *ptrobj =malloc(sizeof(Person)); // memory allocation for struct
ptrobj->firstname = malloc(n); // memory allocation for firstname
ptrobj->surName = malloc(m); // memory allocation for surName

.
. // do whatever you want

free(ptrobj->surName);
free(ptrobj->firstname);
free(ptrobj);

The reason behind this is, if you free the ptrobj first, then there will be memory leaked which is the memory allocated by firstname and suName pointers.

One interesting thing is multiple order by:

according to laravel docs:

DB::table('users')
   ->orderBy('priority', 'desc')
   ->orderBy('email', 'asc')
   ->get();

this means laravel will sort result based on priority attribute. when it's done, it will order result with same priority based on email internally.

My solution was to make all the parents 100% and set a specific percentage for each row:

html, body,div[class^="container"] ,.column {
    height: 100%;
}

.row0 {height: 10%;}
.row1 {height: 40%;}
.row2 {height: 50%;}

All will get executed and On first Called first run basis!!

<div id="target"></div>

<script>
  $(document).ready(function(){
    jQuery('#target').append('target edit 1<br>');
  });
  $(document).ready(function(){
    jQuery('#target').append('target edit 2<br>');
  });
  $(document).ready(function(){
    jQuery('#target').append('target edit 3<br>');
  });
</script>

Demo As you can see they do not replace each other

Also one thing i would like to mention

in place of this

$(document).ready(function(){});

you can use this shortcut

jQuery(function(){
   //dom ready codes
});

Normally you should add:

Options +ExecCGI
 AddType application/x-httpd-php .php .html
 AddHandler x-httpd-php5 .php .html

However for GoDaddy shared hosting (php-cgi), you need to add also these lines:

AddHandler fcgid-script .html
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .html

Here's a good class :

public class Palindrome {

  public static boolean isPalindrome(String stringToTest) {
    String workingCopy = removeJunk(stringToTest);
    String reversedCopy = reverse(workingCopy);

    return reversedCopy.equalsIgnoreCase(workingCopy);
  }

  protected static String removeJunk(String string) {
    int i, len = string.length();
    StringBuffer dest = new StringBuffer(len);
    char c;

    for (i = (len - 1); i >= 0; i--) {
      c = string.charAt(i);
      if (Character.isLetterOrDigit(c)) {
        dest.append(c);
      }
    }

    return dest.toString();
  }

  protected static String reverse(String string) {
    StringBuffer sb = new StringBuffer(string);

    return sb.reverse().toString();
  }

  public static void main(String[] args) {
    String string = "Madam, I'm Adam.";

    System.out.println();
    System.out.println("Testing whether the following "
        + "string is a palindrome:");
    System.out.println("    " + string);
    System.out.println();

    if (isPalindrome(string)) {
      System.out.println("It IS a palindrome!");
    } else {
      System.out.println("It is NOT a palindrome!");
    }
    System.out.println();
  }
}

Enjoy.

Here's an option that stays as true I could make it to the OP's requirement to be able to switch on type. If you squint hard enough it almost looks like a real switch statement.

The calling code looks like this:

var @switch = this.Switch(new []
{
    this.Case<WebControl>(x => { /* WebControl code here */ }),
    this.Case<TextBox>(x => { /* TextBox code here */ }),
    this.Case<ComboBox>(x => { /* ComboBox code here */ }),
});

@switch(obj);

The x in each lambda above is strongly-typed. No casting required.

And to make this magic work you need these two methods:

private Action<object> Switch(params Func<object, Action>[] tests)
{
    return o =>
    {
        var @case = tests
            .Select(f => f(o))
            .FirstOrDefault(a => a != null);

        if (@case != null)
        {
            @case();
        }
    };
}

private Func<object, Action> Case<T>(Action<T> action)
{
    return o => o is T ? (Action)(() => action((T)o)) : (Action)null;
}

Almost brings tears to your eyes, right?

Nonetheless, it works. Enjoy.

if you just run the main.py under the app, just import like

from mymodule import myclass

if you want to call main.py on other folder, use:

from .mymodule import myclass

for example:

+-- app
¦   +-- __init__.py
¦   +-- main.py
¦   +-- mymodule.py
+-- __init__.py
+-- run.py

main.py

from .mymodule import myclass

run.py

from app import main
print(main.myclass)

So I think the main question of you is how to call app.main.

It seems a little tricky since it really had bothered me for a long time.

You just need to open the table (right click the "Select Rows- Limit 10000") and you will open a new window. In this new window, you will find "import icon".

Since you've got both the shell that you're typing into and the shell that sudo -s runs, you need to quote or escape twice. (EDITED fixed quoting)

sudo -su db2inst1 '/opt/ibm/db2/V9.7/bin/db2 force application \(1995\)'

or

sudo -su db2inst1 /opt/ibm/db2/V9.7/bin/db2 force application \\\(1995\\\)

Out of curiosity, why do you need -s? Can't you just do this:

sudo -u db2inst1 /opt/ibm/db2/V9.7/bin/db2 force application \(1995\)

--Use data-interval="false" to stop automatic slide --Use data-wrap="false" to stop circular slide

You can await on Promise.all():

await Promise.all([someCall(), anotherCall()]);

To store the results:

let [someResult, anotherResult] = await Promise.all([someCall(), anotherCall()]);

Note that Promise.all fails fast, which means that as soon as one of the promises supplied to it rejects, then the entire thing rejects.

const happy = (v, ms) => new Promise((resolve) => setTimeout(() => resolve(v), ms))
const sad = (v, ms) => new Promise((_, reject) => setTimeout(() => reject(v), ms))

Promise.all([happy('happy', 100), sad('sad', 50)])
  .then(console.log).catch(console.log) // 'sad'

If, instead, you want to wait for all the promises to either fulfill or reject, then you can use Promise.allSettled. Note that Internet Explorer does not natively support this method.

const happy = (v, ms) => new Promise((resolve) => setTimeout(() => resolve(v), ms))
const sad = (v, ms) => new Promise((_, reject) => setTimeout(() => reject(v), ms))

Promise.allSettled([happy('happy', 100), sad('sad', 50)])
  .then(console.log) // [{ "status":"fulfilled", "value":"happy" }, { "status":"rejected", "reason":"sad" }]

Note: If you use Promise.all actions that managed to finish before rejection happen are not rolled back, so you may need to take care of such situation. For example if you have 5 actions, 4 quick, 1 slow and slow rejects. Those 4 actions may be already executed so you may need to roll back. In such situation consider using Promise.allSettled while it will provide exact detail which action failed and which not.

In unbuffered Input/Output(FileWriter, FileReader) read or write request is handled directly by the underlying OS. https://hajsoftutorial.com/java/wp-content/uploads/2018/04/Unbuffered.gif

This can make a program much less efficient, since each such request often triggers disk access, network activity, or some other operation that is relatively expensive. To reduce this kind of overhead, the Java platform implements buffered I/O streams. The BufferedReader and BufferedWriter classes provide internal character buffers. Text that’s written to a buffered writer is stored in the internal buffer and only written to the underlying writer when the buffer fills up or is flushed. https://hajsoftutorial.com/java/wp-content/uploads/2018/04/bufferedoutput.gif

With C++17 str::string receives data() overload that returns a pointer to modifieable buffer so string can be used in strtok directly without any hacks:

#include <string>

Swift users can check out My Swift Answer for this question.
Or, check out Yedidya Reiss's Answer, which translates this Objective-C code to Swift.

Objective-C Users

The rest of this answer is written in Objective-C

App Store Connect

1. Go to appstoreconnect.apple.com and log in
2. Click My Apps then click the app you want do add the purchase to
3. Click the Features header, and then select In-App Purchases on the left
4. Click the + icon in the middle
5. For this tutorial, we are going to be adding an in-app purchase to remove ads, so choose non-consumable. If you were going to send a physical item to the user, or give them something that they can buy more than once, you would choose consumable.
6. For the reference name, put whatever you want (but make sure you know what it is)
7. For product id put tld.websitename.appname.referencename this will work the best, so for example, you could use com.jojodmo.blix.removeads
8. Choose cleared for sale and then choose price tier as 1 (99¢). Tier 2 would be $1.99, and tier 3 would be $2.99. The full list is available if you click view pricing matrix I recommend you use tier 1, because that's usually the most anyone will ever pay to remove ads.
9. Click the blue add language button, and input the information. This will ALL be shown to the customer, so don't put anything you don't want them seeing
10. For hosting content with Apple choose no
11. You can leave the review notes blank FOR NOW.
12. Skip the screenshot for review FOR NOW, everything we skip we will come back to.
13. Click 'save'

It could take a few hours for your product ID to register in App Store Connect, so be patient.

Setting up your project

Now that you've set up your in-app purchase information on App Store Connect, go into your Xcode project, and go to the application manager (blue page-like icon at the top of where your methods and header files are) click on your app under targets (should be the first one) then go to general. At the bottom, you should see linked frameworks and libraries click the little plus symbol and add the framework StoreKit.framework If you don't do this, the in-app purchase will NOT work!

If you are using Objective-C as the language for your app, you should skip these five steps. Otherwise, if you are using Swift, you can follow My Swift Answer for this question, here, or, if you prefer to use Objective-C for the In-App Purchase code but are using Swift in your app, you can do the following:

1. Create a new .h (header) file by going to File > New > File... (Command ? + N). This file will be referred to as "Your .h file" in the rest of the tutorial

2. When prompted, click Create Bridging Header. This will be our bridging header file. If you are not prompted, go to step 3. If you are prompted, skip step 3 and go directly to step 4.

3. Create another .h file named Bridge.h in the main project folder, Then go to the Application Manager (the blue page-like icon), then select your app in the Targets section, and click Build Settings. Find the option that says Swift Compiler - Code Generation, and then set the Objective-C Bridging Header option to Bridge.h

4. In your bridging header file, add the line #import "MyObjectiveCHeaderFile.h", where MyObjectiveCHeaderFile is the name of the header file that you created in step one. So, for example, if you named your header file InAppPurchase.h, you would add the line #import "InAppPurchase.h" to your bridge header file.

5. Create a new Objective-C Methods (.m) file by going to File > New > File... (Command ? + N). Name it the same as the header file you created in step 1. For example, if you called the file in step 1 InAppPurchase.h, you would call this new file InAppPurchase.m. This file will be referred to as "Your .m file" in the rest of the tutorial.

Coding

Now we're going to get into the actual coding. Add the following code into your .h file:

BOOL areAdsRemoved;

- (IBAction)restore;
- (IBAction)tapsRemoveAds;

Next, you need to import the StoreKit framework into your .m file, as well as add SKProductsRequestDelegate and SKPaymentTransactionObserver after your @interface declaration:

#import <StoreKit/StoreKit.h>

//put the name of your view controller in place of MyViewController
@interface MyViewController() <SKProductsRequestDelegate, SKPaymentTransactionObserver>

@end

@implementation MyViewController //the name of your view controller (same as above)
  //the code below will be added here
@end

and now add the following into your .m file, this part gets complicated, so I suggest that you read the comments in the code:

//If you have more than one in-app purchase, you can define both of
//of them here. So, for example, you could define both kRemoveAdsProductIdentifier
//and kBuyCurrencyProductIdentifier with their respective product ids
//
//for this example, we will only use one product

#define kRemoveAdsProductIdentifier @"put your product id (the one that we just made in App Store Connect) in here"

- (IBAction)tapsRemoveAds{
    NSLog(@"User requests to remove ads");

    if([SKPaymentQueue canMakePayments]){
        NSLog(@"User can make payments");
    
        //If you have more than one in-app purchase, and would like
        //to have the user purchase a different product, simply define 
        //another function and replace kRemoveAdsProductIdentifier with 
        //the identifier for the other product

        SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:kRemoveAdsProductIdentifier]];
        productsRequest.delegate = self;
        [productsRequest start];
    
    }
    else{
        NSLog(@"User cannot make payments due to parental controls");
        //this is called the user cannot make payments, most likely due to parental controls
    }
}

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
    SKProduct *validProduct = nil;
    int count = [response.products count];
    if(count > 0){
        validProduct = [response.products objectAtIndex:0];
        NSLog(@"Products Available!");
        [self purchase:validProduct];
    }
    else if(!validProduct){
        NSLog(@"No products available");
        //this is called if your product id is not valid, this shouldn't be called unless that happens.
    }
}

- (void)purchase:(SKProduct *)product{
    SKPayment *payment = [SKPayment paymentWithProduct:product];

    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] addPayment:payment];
}

- (IBAction) restore{
    //this is called when the user restores purchases, you should hook this up to a button
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}

- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
    NSLog(@"received restored transactions: %i", queue.transactions.count);
    for(SKPaymentTransaction *transaction in queue.transactions){
        if(transaction.transactionState == SKPaymentTransactionStateRestored){
            //called when the user successfully restores a purchase
            NSLog(@"Transaction state -> Restored");

            //if you have more than one in-app purchase product,
            //you restore the correct product for the identifier.
            //For example, you could use
            //if(productID == kRemoveAdsProductIdentifier)
            //to get the product identifier for the
            //restored purchases, you can use
            //
            //NSString *productID = transaction.payment.productIdentifier;
            [self doRemoveAds];
            [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
            break;
        }
    }   
}

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
    for(SKPaymentTransaction *transaction in transactions){
        //if you have multiple in app purchases in your app,
        //you can get the product identifier of this transaction
        //by using transaction.payment.productIdentifier
        //
        //then, check the identifier against the product IDs
        //that you have defined to check which product the user
        //just purchased            

        switch(transaction.transactionState){
            case SKPaymentTransactionStatePurchasing: NSLog(@"Transaction state -> Purchasing");
                //called when the user is in the process of purchasing, do not add any of your own code here.
                break;
            case SKPaymentTransactionStatePurchased:
            //this is called when the user has successfully purchased the package (Cha-Ching!)
                [self doRemoveAds]; //you can add your code for what you want to happen when the user buys the purchase here, for this tutorial we use removing ads
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                NSLog(@"Transaction state -> Purchased");
                break;
            case SKPaymentTransactionStateRestored:
                NSLog(@"Transaction state -> Restored");
                //add the same code as you did from SKPaymentTransactionStatePurchased here
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
            case SKPaymentTransactionStateFailed:
                //called when the transaction does not finish
                if(transaction.error.code == SKErrorPaymentCancelled){
                    NSLog(@"Transaction state -> Cancelled");
                    //the user cancelled the payment ;(
                }
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
        }
    }
}

Now you want to add your code for what will happen when the user finishes the transaction, for this tutorial, we use removing adds, you will have to add your own code for what happens when the banner view loads.

- (void)doRemoveAds{
    ADBannerView *banner;
    [banner setAlpha:0];
    areAdsRemoved = YES;
    removeAdsButton.hidden = YES;
    removeAdsButton.enabled = NO;
    [[NSUserDefaults standardUserDefaults] setBool:areAdsRemoved forKey:@"areAdsRemoved"];
    //use NSUserDefaults so that you can load whether or not they bought it
    //it would be better to use KeyChain access, or something more secure
    //to store the user data, because NSUserDefaults can be changed.
    //You're average downloader won't be able to change it very easily, but
    //it's still best to use something more secure than NSUserDefaults.
    //For the purpose of this tutorial, though, we're going to use NSUserDefaults
    [[NSUserDefaults standardUserDefaults] synchronize];
}

If you don't have ads in your application, you can use any other thing that you want. For example, we could make the color of the background blue. To do this we would want to use:

- (void)doRemoveAds{
    [self.view setBackgroundColor:[UIColor blueColor]];
    areAdsRemoved = YES
    //set the bool for whether or not they purchased it to YES, you could use your own boolean here, but you would have to declare it in your .h file

    [[NSUserDefaults standardUserDefaults] setBool:areAdsRemoved forKey:@"areAdsRemoved"];
    //use NSUserDefaults so that you can load wether or not they bought it
    [[NSUserDefaults standardUserDefaults] synchronize];
}

Now, somewhere in your viewDidLoad method, you're going to want to add the following code:

areAdsRemoved = [[NSUserDefaults standardUserDefaults] boolForKey:@"areAdsRemoved"];
[[NSUserDefaults standardUserDefaults] synchronize];
//this will load wether or not they bought the in-app purchase

if(areAdsRemoved){
    [self.view setBackgroundColor:[UIColor blueColor]];
    //if they did buy it, set the background to blue, if your using the code above to set the background to blue, if your removing ads, your going to have to make your own code here
}

Now that you have added all the code, go into your .xib or storyboard file, and add two buttons, one saying purchase, and the other saying restore. Hook up the tapsRemoveAds IBAction to the purchase button that you just made, and the restore IBAction to the restore button. The restore action will check if the user has previously purchased the in-app purchase, and give them the in-app purchase for free if they do not already have it.

Submitting for review

Next, go into App Store Connect, and click Users and Access then click the Sandbox Testers header, and then click the + symbol on the left where it says Testers. You can just put in random things for the first and last name, and the e-mail does not have to be real - you just have to be able to remember it. Put in a password (which you will have to remember) and fill in the rest of the info. I would recommend that you make the Date of Birth a date that would make the user 18 or older. App Store Territory HAS to be in the correct country. Next, log out of your existing iTunes account (you can log back in after this tutorial).

Now, run your application on your iOS device, if you try running it on the simulator, the purchase will always error, you HAVE TO run it on your iOS device. Once the app is running, tap the purchase button. When you are prompted to log into your iTunes account, log in as the test user that we just created. Next,when it asks you to confirm the purchase of 99¢ or whatever you set the price tier too, TAKE A SCREEN SNAPSHOT OF IT this is what your going to use for your screenshot for review on App Store Connect. Now cancel the payment.

Now, go to App Store Connect, then go to My Apps > the app you have the In-app purchase on > In-App Purchases. Then click your in-app purchase and click edit under the in-app purchase details. Once you've done that, import the photo that you just took on your iPhone into your computer, and upload that as the screenshot for review, then, in review notes, put your TEST USER e-mail and password. This will help apple in the review process.

After you have done this, go back onto the application on your iOS device, still logged in as the test user account, and click the purchase button. This time, confirm the payment Don't worry, this will NOT charge your account ANY money, test user accounts get all in-app purchases for free After you have confirmed the payment, make sure that what happens when the user buys your product actually happens. If it doesn't, then thats going to be an error with your doRemoveAds method. Again, I recommend using changing the background to blue for testing the in-app purchase, this should not be your actual in-app purchase though. If everything works and you're good to go! Just make sure to include the in-app purchase in your new binary when you upload it to App Store Connect!

Here are some common errors:

Logged: No Products Available

This could mean four things:

• You didn't put the correct in-app purchase ID in your code (for the identifier kRemoveAdsProductIdentifier in the above code
• You didn't clear your in-app purchase for sale on App Store Connect
• You didn't wait for the in-app purchase ID to be registered in App Store Connect. Wait a couple hours from creating the ID, and your problem should be resolved.
• You didn't complete filling your Agreements, Tax, and Banking info.

If it doesn't work the first time, don't get frustrated! Don't give up! It took me about 5 hours straight before I could get this working, and about 10 hours searching for the right code! If you use the code above exactly, it should work fine. Feel free to comment if you have any questions at all.

I hope this helps to all of those hoping to add an in-app purchase to their iOS application. Cheers!

Hi solution mentioned by Damien McGivern, Works on IIS6 only,

It does not work on IIS7 and ASP.NET Development Server. I get page displaying "404 - File or directory not found."

Any ideas?

EDIT:

Got it... This solution still doesn't work on ASP.NET Development Server, but I got the reason why it was not working on IIS7 in my case.

The reason is IIS7 has a built-in request scanning which imposes an upload file cap which defaults to 30000000 bytes (which is slightly less that 30MB).

And I was trying to upload file of size 100 MB to test the solution mentioned by Damien McGivern (with maxRequestLength="10240" i.e. 10MB in web.config). Now, If I upload the file of size > 10MB and < 30 MB then the page is redirected to the specified error page. But if the file size is > 30MB then it show the ugly built-in error page displaying "404 - File or directory not found."

So, to avoid this, you have to increase the max. allowed request content length for your website in IIS7. That can be done using following command,

appcmd set config "SiteName" -section:requestFiltering -requestLimits.maxAllowedContentLength:209715200 -commitpath:apphost

I have set the max. content length to 200MB.

After doing this setting, the page is succssfully redirected to my error page when I try to upload file of 100MB

Refer, http://weblogs.asp.net/jgalloway/archive/2008/01/08/large-file-uploads-in-asp-net.aspx for more details.

iOS 11 / Xcode 9

<#yourElement#>.waitForExistence(timeout: 5)

This is a great replacement for all the custom implementations on this site!

Be sure to have a look at my answer here: https://stackoverflow.com/a/48937714/971329. There I describe an alternative to waiting for requests which will greatly reduce the time your tests are running!

One advantage (albeit very slight) of defining string constants is that you can concatenate them at compile time:

#define HELLO "hello"
#define WORLD "world"

puts( HELLO WORLD );

Not sure that's really an advantage, but it is a technique that cannot be used with const char *'s.

Try use absolute path:

exclude:path.resolve(__dirname, "node_modules")

A "sort merge" join is performed by sorting the two data sets to be joined according to the join keys and then merging them together. The merge is very cheap, but the sort can be prohibitively expensive especially if the sort spills to disk. The cost of the sort can be lowered if one of the data sets can be accessed in sorted order via an index, although accessing a high proportion of blocks of a table via an index scan can also be very expensive in comparison to a full table scan.

A hash join is performed by hashing one data set into memory based on join columns and reading the other one and probing the hash table for matches. The hash join is very low cost when the hash table can be held entirely in memory, with the total cost amounting to very little more than the cost of reading the data sets. The cost rises if the hash table has to be spilled to disk in a one-pass sort, and rises considerably for a multipass sort.

(In pre-10g, outer joins from a large to a small table were problematic performance-wise, as the optimiser could not resolve the need to access the smaller table first for a hash join, but the larger table first for an outer join. Consequently hash joins were not available in this situation).

The cost of a hash join can be reduced by partitioning both tables on the join key(s). This allows the optimiser to infer that rows from a partition in one table will only find a match in a particular partition of the other table, and for tables having n partitions the hash join is executed as n independent hash joins. This has the following effects:

1. The size of each hash table is reduced, hence reducing the maximum amount of memory required and potentially removing the need for the operation to require temporary disk space.
2. For parallel query operations the amount of inter-process messaging is vastly reduced, reducing CPU usage and improving performance, as each hash join can be performed by one pair of PQ processes.
3. For non-parallel query operations the memory requirement is reduced by a factor of n, and the first rows are projected from the query earlier.

You should note that hash joins can only be used for equi-joins, but merge joins are more flexible.

In general, if you are joining large amounts of data in an equi-join then a hash join is going to be a better bet.

This topic is very well covered in the documentation.

http://download.oracle.com/docs/cd/B28359_01/server.111/b28274/optimops.htm#i51523

12.1 docs: https://docs.oracle.com/database/121/TGSQL/tgsql_join.htm

I stumble upon this question and it grabbed my interest. The accepted answer is completely correct, but I thought I do provide my findings at JVM byte code level to explain why the OP encounter the ClassCastException.

I have the code which is pretty much the same as OP's code:

public static <T> T convertInstanceOfObject(Object o) {
    try {
       return (T) o;
    } catch (ClassCastException e) {
        return null;
    }
}

public static void main(String[] args) {
    String k = convertInstanceOfObject(345435.34);
    System.out.println(k);
}

and the corresponding byte code is:

public static <T> T convertInstanceOfObject(java.lang.Object);
    Code:
       0: aload_0
       1: areturn
       2: astore_1
       3: aconst_null
       4: areturn
    Exception table:
       from    to  target type
           0     1     2   Class java/lang/ClassCastException

  public static void main(java.lang.String[]);
    Code:
       0: ldc2_w        #3                  // double 345435.34d
       3: invokestatic  #5                  // Method java/lang/Double.valueOf:(D)Ljava/lang/Double;
       6: invokestatic  #6                  // Method convertInstanceOfObject:(Ljava/lang/Object;)Ljava/lang/Object;
       9: checkcast     #7                  // class java/lang/String
      12: astore_1
      13: getstatic     #8                  // Field java/lang/System.out:Ljava/io/PrintStream;
      16: aload_1
      17: invokevirtual #9                  // Method java/io/PrintStream.println:(Ljava/lang/String;)V
      20: return

Notice that checkcast byte code instruction happens in the main method not the convertInstanceOfObject and convertInstanceOfObject method does not have any instruction that can throw ClassCastException. Because the main method does not catch the ClassCastException hence when you execute the main method you will get a ClassCastException and not the expectation of printing null.

Now I modify the code to the accepted answer:

public static <T> T convertInstanceOfObject(Object o, Class<T> clazz) {
        try {
            return clazz.cast(o);
        } catch (ClassCastException e) {
            return null;
        }
    }
    public static void main(String[] args) {
        String k = convertInstanceOfObject(345435.34, String.class);
        System.out.println(k);
    }

The corresponding byte code is:

public static <T> T convertInstanceOfObject(java.lang.Object, java.lang.Class<T>);
    Code:
       0: aload_1
       1: aload_0
       2: invokevirtual #2                  // Method java/lang/Class.cast:(Ljava/lang/Object;)Ljava/lang/Object;
       5: areturn
       6: astore_2
       7: aconst_null
       8: areturn
    Exception table:
       from    to  target type
           0     5     6   Class java/lang/ClassCastException

  public static void main(java.lang.String[]);
    Code:
       0: ldc2_w        #4                  // double 345435.34d
       3: invokestatic  #6                  // Method java/lang/Double.valueOf:(D)Ljava/lang/Double;
       6: ldc           #7                  // class java/lang/String
       8: invokestatic  #8                  // Method convertInstanceOfObject:(Ljava/lang/Object;Ljava/lang/Class;)Ljava/lang/Object;
      11: checkcast     #7                  // class java/lang/String
      14: astore_1
      15: getstatic     #9                  // Field java/lang/System.out:Ljava/io/PrintStream;
      18: aload_1
      19: invokevirtual #10                 // Method java/io/PrintStream.println:(Ljava/lang/String;)V
      22: return

Notice that there is an invokevirtual instruction in the convertInstanceOfObject method that calls Class.cast() method which throws ClassCastException which will be catch by the catch(ClassCastException e) bock and return null; hence, "null" is printed to console without any exception.

The jQuery documentation says that the datePicker needs to be attached to a SPAN or a DIV when it is not associated with an input box. You could do something like this:

<img src='someimage.gif' id="datepickerImage" />
<div id="datepicker"></div>

<script type="text/javascript">
 $(document).ready(function() {
    $("#datepicker").datepicker({
            changeMonth: true,
            changeYear: true,
    })
    .hide()
    .click(function() {
      $(this).hide();
    });

    $("#datepickerImage").click(function() {
       $("#datepicker").show(); 
    });
 });
</script>

Non-javascript way . . aspx page:

 <form id="form1" runat="server">
<div>
    <asp:CheckBox ID="CheckBox1" runat="server" />
    <asp:CustomValidator ID="CustomValidator1"
        runat="server" ErrorMessage="CustomValidator" ControlToValidate="CheckBox1"></asp:CustomValidator>
</div>
</form>

Code Behind:

Protected Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate
    If Not CheckBox1.Checked Then
        args.IsValid = False
    End If
End Sub

For any actions you might need (business Rules):

If Page.IsValid Then
   'do logic
End If 

Sorry for the VB code . . . you can convert it to C# if that is your pleasure. The company I am working for right now requires VB :(

Firstly, your example is looking quite correct and works well on my machine. You may go another way.

curl $CURLARGS $RVMHTTP > ./install.sh

All output now storing in ./install.sh file, which you can edit and execute.

public class WebViewController extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }
}
webView.setWebViewClient(new WebViewController());

If you are not in an Rails environment (ie. don't have ActiveRecord available), this may be helpful:

JSON.parse( object.to_json )

If you need an easier way to do it, and don't want much fuss, a simple execution could be:

raise Exception.new('something bad happened!')

This will raise an exception, say e with e.message = something bad happened!

and then you can rescue it as you are rescuing all other exceptions in general.

I've used this with great success:

Using AFNetworking 3.0, you should write:

NSString *strURL = @"https://exampleWeb.com/webserviceOBJ";
NSURL * urlStr = [NSURL URLWithString:strURL];

NSDictionary *dictParameters = @{@"user[height]": height,@"user[weight]": weight};

AFHTTPSessionManager * manager = [AFHTTPSessionManager manager];


[manager POST:url.absoluteString parameters:dictParameters success:^(NSURLSessionTask *task, id responseObject) {
    NSLog(@"PLIST: %@", responseObject);
   
} failure:^(NSURLSessionTask *operation, NSError *error) {
    NSLog(@"Error: %@", error);
    
}];

First check whether the file exists in SDCard. If the file doesnot exists in SDcard then you can set image using setImageResource() methodand passing default image from drawable folder

Sample Code

File imageFile = new File(absolutepathOfImage);//absolutepathOfImage is absolute path of image including its name
        if(!imageFile.exists()){//file doesnot exist in SDCard

        imageview.setImageResource(R.drawable.defaultImage);//set default image from drawable folder
        }

SELECT date_column_name FROM table_name WHERE EXTRACT(YEAR FROM date_column_name) = 2020

Use below bash command to locate all virtual env in your system. You can modify the command according to your need to get in your desired format.

locate --regex "bin/activate"$ | sed 's/bin\/activate$//'

What you should be looking at is Import-Csv

Once you import the CSV you can use the column header as the variable.

Now we will import the CSV, and loop through the list to add to an array. We can then compare the value input to the array:

$Name = @()
$Phone = @()

Import-Csv H:\Programs\scripts\SomeText.csv |`
    ForEach-Object {
        $Name += $_.Name
        $Phone += $_."Phone Number"
    }

$inputNumber = Read-Host -Prompt "Phone Number"

if ($Phone -contains $inputNumber)
    {
    Write-Host "Customer Exists!"
    $Where = [array]::IndexOf($Phone, $inputNumber)
    Write-Host "Customer Name: " $Name[$Where]
    }

And here is the output:

Well, you pretty much gave yourself the answer. In your CSS give the containing element a min-width. If you have to support IE6 you can use the min-width-trick:

#container {
    min-width:800px;
    width: auto !important;
    width:800px;
}

That will effectively give you 800px min-width in IE6 and any up-to-date browsers.

I use generally this:

std::string& replace(std::string& s, const std::string& from, const std::string& to)
{
    if(!from.empty())
        for(size_t pos = 0; (pos = s.find(from, pos)) != std::string::npos; pos += to.size())
            s.replace(pos, from.size(), to);
    return s;
}

It repeatedly calls std::string::find() to locate other occurrences of the searched for string until std::string::find() doesn't find anything. Because std::string::find() returns the position of the match we don't have the problem of invalidating iterators.

After calling GroupBy, you get a series of groups IEnumerable<Grouping>, where each Grouping itself exposes the Key used to create the group and also is an IEnumerable<T> of whatever items are in your original data set. You just have to call Count() on that Grouping to get the subtotal.

foreach(var line in data.GroupBy(info => info.metric)
                        .Select(group => new { 
                             Metric = group.Key, 
                             Count = group.Count() 
                        })
                        .OrderBy(x => x.Metric))
{
     Console.WriteLine("{0} {1}", line.Metric, line.Count);
}

I'm assuming you already have a list/array of some class that looks like

class UserInfo {
    string name;
    int metric;
    ..etc..
} 
...
List<UserInfo> data = ..... ;

When you do data.GroupBy(x => x.metric), it means "for each element x in the IEnumerable defined by data, calculate it's .metric, then group all the elements with the same metric into a Grouping and return an IEnumerable of all the resulting groups. Given your example data set of

    <DATA>           | Grouping Key (x=>x.metric) |
joe  1 01/01/2011 5  | 1
jane 0 01/02/2011 9  | 0
john 2 01/03/2011 0  | 2
jim  3 01/04/2011 1  | 3
jean 1 01/05/2011 3  | 1
jill 2 01/06/2011 5  | 2
jeb  0 01/07/2011 3  | 0
jenn 0 01/08/2011 7  | 0

it would result in the following result after the groupby:

(Group 1): [joe  1 01/01/2011 5, jean 1 01/05/2011 3]
(Group 0): [jane 0 01/02/2011 9, jeb  0 01/07/2011 3, jenn 0 01/08/2011 7]
(Group 2): [john 2 01/03/2011 0, jill 2 01/06/2011 5]
(Group 3): [jim  3 01/04/2011 1]

First you need to add a provider to your AndroidManifest

  <application
    ...>
    <activity>
    .... 
    </activity>
    <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="com.your.package.fileProvider"
        android:grantUriPermissions="true"
        android:exported="false">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths" />
    </provider>
  </application>

now create a file in xml resource folder (if using android studio you can hit Alt + Enter after highlighting file_paths and select create a xml resource option)

Next in the file_paths file enter

<?xml version="1.0" encoding="utf-8"?>
<paths>
  <external-path path="Android/data/com.your.package/" name="files_root" />
  <external-path path="." name="external_storage_root" />
</paths>

This example is for external-path you can refere here for more options. This will allow you to share files which are in that folder and its sub-folder.

Now all that's left is to create the intent as follows:

    MimeTypeMap mime = MimeTypeMap.getSingleton();
    String ext = newFile.getName().substring(newFile.getName().lastIndexOf(".") + 1);
    String type = mime.getMimeTypeFromExtension(ext);
    try {
        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_VIEW);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            Uri contentUri = FileProvider.getUriForFile(getContext(), "com.your.package.fileProvider", newFile);
            intent.setDataAndType(contentUri, type);
        } else {
            intent.setDataAndType(Uri.fromFile(newFile), type);
        }
        startActivityForResult(intent, ACTIVITY_VIEW_ATTACHMENT);
    } catch (ActivityNotFoundException anfe) {
        Toast.makeText(getContext(), "No activity found to open this attachment.", Toast.LENGTH_LONG).show();
    }

EDIT: I added the root folder of the sd card in the file_paths. I have tested this code and it does work.

In case you want to cast to a class and not just a string:

YourClass model = await request.Content.ReadAsAsync<YourClass>();

InnoDB works slightly different that MyISAM and they both are viable options. You should use what you think it fits the project.

Some keypoints will be:

1. InnoDB does ACID-compliant transaction. http://en.wikipedia.org/wiki/ACID
2. InnoDB does Referential Integrity (foreign key relations) http://www.w3resource.com/sql/joins/joining-tables-through-referential-integrity.php
3. MyIsam does full text search, InnoDB doesn't
4. I have been told InnoDB is faster on executing writes but slower than MyISAM doing reads (I cannot back this up and could not find any article that analyses this, I do however have the guy that told me this in high regard), feel free to ignore this point or do your own research.
5. Default configuration does not work very well for InnoDB needs to be tweaked accordingly, run a tool like http://mysqltuner.pl/mysqltuner.pl to help you.

Notes:

• In my opinion the second point is probably the one were InnoDB has a huge advantage over MyISAM.
• Full text search not working with InnoDB is a bit of a pain, You can mix different storage engines but be careful when doing so.

Notes2: - I am reading this book "High performance MySQL", the author says "InnoDB loads data and creates indexes slower than MyISAM", this could also be a very important factor when deciding what to use.

The best way in any case is to check the length of the given string.For this if your string is myString then the code is:

    int len = [myString length];
    if(len == 0){
       NSLog(@"String is empty");
    }
    else{
      NSLog(@"String is : %@", myString);
    }

I encountered a similar problem, and I used 2 flash drives as 'ReadyBoost'. The two drives gave additional 8GB boost of memory (for cache) and it solved the problem and also increased the speed of the system as a whole. To use Readyboost, right click on the drive, go to properties and select 'ReadyBoost' and select 'use this device' radio button and click apply or ok to configure.

Following snippet will do the desired function:

Type t = obj.GetType(); // Where obj is object whose properties you need.
PropertyInfo [] pi = t.GetProperties();
foreach (PropertyInfo p in pi)
{
    System.Console.WriteLine(p.Name + " : " + p.GetValue(obj));
}

I think if you write this as extension method you could use it on all type of objects.

You can embed a manifest file in the EXE file, which will cause Windows (7 or higher) to always run the program as an administrator.

You can find more details in Step 6: Create and Embed an Application Manifest (UAC) (MSDN).

Follow below steps:

1) First go to Server Explorer in Visual Studio, check if the ".mdf" Data Connections for this project are connected, if so, right click and delete.

2 )Go to Solution Explorer, click show All Files icon.

3) Go to App_Data, right click and delete all ".mdf" files for this project.

4) Delete Migrations folder by right click and delete.

5) Go to SQL Server Management Studio, make sure the DB for this project is not there, otherwise delete it.

6) Go to Package Manager Console in Visual Studio and type:

1. Enable-Migrations -Force
2. Add-Migration init
3. Update-Database

7) Run your application

Note: In step 6 part 3, if you get an error "Cannot attach the file...", it is possibly because you didn't delete the database files completely in SQL Server.

Other options:

#multi line string
multiline_string = <<EOM
This is a very long string
that contains interpolation
like #{4 + 5} \n\n
EOM

puts multiline_string

#another option for multiline string
message = <<-EOF
asdfasdfsador #{2+2} this month.
asdfadsfasdfadsfad.
EOF

puts message

I do that the following way:

NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"/MyFolder"];

if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
    [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder

I do not know why there is no answer directly addressing the problem. When you want to compile C++ program, it is best to use clang++. For example, the following works for me:

clang++ -Wall -std=c++11 test.cc -o test

If compiled correctly, it will produce the executable file test, and you can run the file by using ./test.

Or you can just use clang++ test.cc to compile the program. It will produce a default executable file named a.out. Use ./a.out to run the file.

The whole process is a lot like g++ if you are familiar with g++. See this post to check which warnings are included with -Wall option. This page shows a list of diagnostic flags supported by Clang.

A note on using clang -x c++: Kim Gräsman says that you can also use clang -x c++ to compile cpp programs, but that may not be true. For example, I am having a simple program below:

#include <iostream>
#include <vector>

int main() {
    /* std::vector<int> v = {1, 2, 3, 4, 5}; */
    std::vector<int> v(10, 5);
    int sum = 0;
    for (int i = 0; i < v.size(); i++){
        sum += v[i]*2;
    }
    std::cout << "sum is " << sum << std::endl;
    return 0;
}                                                      

clang++ test.cc -o test will compile successfully, but clang -x c++ will not, showing a lot undefined references errors. So I guess they are not exactly equivalent. It is best to use clang++ instead of clang -x c++ when compiling c++ programs to avoid extra troubles.

• clang version: 11.0.0

There is a way to create war file of your project from eclipse.

First a create an xml file with the following code,

Replace HistoryCheck with your project name.

<?xml version="1.0" encoding="UTF-8"?>
<project name="HistoryCheck" basedir="." default="default">
    <target name="default" depends="buildwar,deploy"></target>
    <target name="buildwar">
        <war basedir="war" destfile="HistoryCheck.war" webxml="war/WEB-INF/web.xml">
            <exclude name="WEB-INF/**" />
            <webinf dir="war/WEB-INF/">
                <include name="**/*.jar" />
            </webinf>
        </war>
    </target>
    <target name="deploy">
        <copy file="HistoryCheck.war" todir="." />
    </target>
</project>

Now, In project explorer right click on that xml file and Run as-> ant build

You can see the war file of your project in your project folder.

The advantages of an abstract class are:

• Ability to specify default implementations of methods
• Added invariant checking to functions
• Have slightly more control in how the "interface" methods are called
• Ability to provide behavior related or unrelated to the interface for "free"

Interfaces are merely data passing contracts and do not have these features. However, they are typically more flexible as a type can only be derived from one class, but can implement any number of interfaces.

By either escaping those characters with htmlspecialchars, or, perhaps more appropriately, using a library for building XML documents, such as DOMDocument or XMLWriter.

Another alternative would be to use CDATA sections, but then you'd have to look out for occurrences of ]]>.

Take also into consideration that that you must respect the encoding you define for the XML document (by default UTF-8).

I have also dealt with this exception after a fully working context.xml setup was adjusted. I didn't want environment details in the context.xml, so I took them out and saw this error. I realized I must fully create this datasource resource in code based on System Property JVM -D args.

Original error with just user/pwd/host removed: org.apache.tomcat.jdbc.pool.ConnectionPool init SEVERE: Unable to create initial connections of pool.

Removed entire contents of context.xml and try this: Initialize on startup of app server the datasource object sometime before using first connection. If using Spring this is good to do in an @Configuration bean in @Bean Datasource constructor.

package to use: org.apache.tomcat.jdbc.pool.*

            p.setRemoveAbandoned(true);
            p.setJdbcInterceptors(
              "org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;"+
              "org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer");
            org.apache.tomcat.jdbc.pool.DataSource ds = new org.apache.tomcat.jdbc.pool.DataSource();
            ds.setPoolProperties(p);
            return ds;

The problem is on this line:

oShell.run "cmd.exe /C copy "S:Claims\Sound.wav" "C:\WINDOWS\Media\Sound.wav"

Your first quote next to "S:Claims" ends the string; you need to escape the quotes around your files with a second quote, like this:

oShell.run "cmd.exe /C copy ""S:\Claims\Sound.wav"" ""C:\WINDOWS\Media\Sound.wav"" "

You also have a typo in S:Claims\Sound.wav, should be S:\Claims\Sound.wav.

I also assume the apostrophe before Dim oShell and after Set oShell = Nothing are typos as well.

PHP 7.2 Ubuntu 18.04

sudo apt install php-mbstring

HashMap compatible Pair class:

public class Pair<A, B> {
    private A first;
    private B second;

    public Pair(A first, B second) {
        super();
        this.first = first;
        this.second = second;
    }

    public int hashCode() {
        int hashFirst = first != null ? first.hashCode() : 0;
        int hashSecond = second != null ? second.hashCode() : 0;

        return (hashFirst + hashSecond) * hashSecond + hashFirst;
    }

    public boolean equals(Object other) {
        if (other instanceof Pair) {
            Pair otherPair = (Pair) other;
            return 
            ((  this.first == otherPair.first ||
                ( this.first != null && otherPair.first != null &&
                  this.first.equals(otherPair.first))) &&
             (  this.second == otherPair.second ||
                ( this.second != null && otherPair.second != null &&

You can do these checks using positive look ahead assertions:

^(?=.*[A-Z].*[A-Z])(?=.*[!@#$&*])(?=.*[0-9].*[0-9])(?=.*[a-z].*[a-z].*[a-z]).{8}$

Rubular link

Explanation:

^                         Start anchor
(?=.*[A-Z].*[A-Z])        Ensure string has two uppercase letters.
(?=.*[!@#$&*])            Ensure string has one special case letter.
(?=.*[0-9].*[0-9])        Ensure string has two digits.
(?=.*[a-z].*[a-z].*[a-z]) Ensure string has three lowercase letters.
.{8}                      Ensure string is of length 8.
$                         End anchor.

Here T refers to a Class.It can be a reference type.

For spring :

File inputFile = new ClassPathResource("\\chrome\\chromedriver.exe").getFile();
System.setProperty("webdriver.chrome.driver",inputFile.getCanonicalPath());

https://github.com/blueimp/JavaScript-Load-Image is a modern javascript library that can not only extract the exif orientation flag - it can also correctly mirror/rotate JPEG images on the client side.

I just solved the same problem with this library: JS Client-Side Exif Orientation: Rotate and Mirror JPEG Images

I had to download the zip from git hub and drag the missing files into the Finder at corresponding paths in Pod/...

The best way is using "DEFAULT 0". Other way:

    /************ ROLE ************/
    drop table if exists `role`;
    create table `role` (
        `id_role` bigint(20) unsigned not null auto_increment,
        `date_created` datetime,
        `date_deleted` datetime,
        `name` varchar(35) not null,
        `description` text,
        primary key (`id_role`)
    ) comment='';

    drop trigger if exists `role_date_created`;
    create trigger `role_date_created` before insert
        on `role`
        for each row 
        set new.`date_created` = now();

[your_imageview setContentMode:UIViewContentModeCenter];

You could print the backspace character \b as many times as the characters which were printed before.

System.out.print("hello");
Thread.sleep(1000); // Just to give the user a chance to see "hello".
System.out.print("\b\b\b\b\b");
System.out.print("world");

Note: this doesn't work flawlessly in Eclipse console in older releases before Mars (4.5). This works however perfectly fine in command console. See also How to get backspace \b to work in Eclipse's console?

Reasons why id based selectors don't work

1. The element/DOM with id specified doesn't exist yet.
2. The element exists, but it is not registered in DOM [in case of HTML nodes appended dynamically from Ajax responses].
3. More than one element with the same id is present which is causing a conflict.

Solutions

1. Try to access the element after its declaration or alternatively use stuff like $(document).ready();

2. For elements coming from Ajax responses, use the .bind() method of jQuery. Older versions of jQuery had .live() for the same.

3. Use tools [for example, webdeveloper plugin for browsers] to find duplicate ids and remove them.

For correct form data usage you need to do 2 steps.

Preparations

You can give your whole form to FormData() for processing

var form = $('form')[0]; // You need to use standard javascript object here
var formData = new FormData(form);

or specify exact data for FormData()

var formData = new FormData();
formData.append('section', 'general');
formData.append('action', 'previewImg');
// Attach file
formData.append('image', $('input[type=file]')[0].files[0]); 

Sending form

Ajax request with jquery will looks like this:

$.ajax({
    url: 'Your url here',
    data: formData,
    type: 'POST',
    contentType: false, // NEEDED, DON'T OMIT THIS (requires jQuery 1.6+)
    processData: false, // NEEDED, DON'T OMIT THIS
    // ... Other options like success and etc
});

After this it will send ajax request like you submit regular form with enctype="multipart/form-data"

Update: This request cannot work without type:"POST" in options since all files must be sent via POST request.

Note: contentType: false only available from jQuery 1.6 onwards

I would recommend at least Eclipse Indigo (v 3.7) for Android Development because even though a minimum of Helios (v 3.6) is required for ADT 22.0.1 as explained here...

http://developer.android.com/tools/sdk/eclipse-adt.html

... Indigo is required for Android NDK development using CDT, as explained here:

Here's a nice function that allows this:

public static void animateBetweenColors(final @NonNull View viewToAnimateItsBackground, final int colorFrom,
                                        final int colorTo, final int durationInMs) {
    final ColorDrawable colorDrawable = new ColorDrawable(durationInMs > 0 ? colorFrom : colorTo);
    ViewCompat.setBackground(viewToAnimateItsBackground, colorDrawable);
    if (durationInMs > 0) {
        final ValueAnimator colorAnimation = ValueAnimator.ofObject(new ArgbEvaluator(), colorFrom, colorTo);
        colorAnimation.addUpdateListener(animator -> {
            colorDrawable.setColor((Integer) animator.getAnimatedValue());
            ViewCompat.setBackground(viewToAnimateItsBackground, colorDrawable);
        });
        colorAnimation.setDuration(durationInMs);
        colorAnimation.start();
    }
}

And in Kotlin:

@JvmStatic
fun animateBetweenColors(viewToAnimateItsBackground: View, colorFrom: Int, colorTo: Int, durationInMs: Int) {
    val colorDrawable = ColorDrawable(if (durationInMs > 0) colorFrom else colorTo)
    ViewCompat.setBackground(viewToAnimateItsBackground, colorDrawable)
    if (durationInMs > 0) {
        val colorAnimation = ValueAnimator.ofObject(ArgbEvaluator(), colorFrom, colorTo)
        colorAnimation.addUpdateListener { animator: ValueAnimator ->
            colorDrawable.color = (animator.animatedValue as Int)
            ViewCompat.setBackground(viewToAnimateItsBackground, colorDrawable)
        }
        colorAnimation.duration = durationInMs.toLong()
        colorAnimation.start()
    }
}

What if the ad provider's view is not added to self.view but to something like [UIApplication sharedApplication].keyWindow?

Try something like:

[[UIApplication sharedApplication].keyWindow addSubview:yourSubview]

or

[[UIApplication sharedApplication].keyWindow bringSubviewToFront:yourSubview]

This answer is likely wrong wrong the context. I thought VBA now run on the CLR these days, but it does not. In any case, this reply may be useful to someone. Or not.

If you run Office 2010 32-bit mode then it's the same as Office 2007. (The "issue" is Office running in 64-bit mode). It's the bitness of the execution context (VBA/CLR) which is important here and the bitness of the loaded VBA/CLR depends upon the bitness of the host process.

Between 32/64-bit calls, most notable things that go wrong are using long or int (constant-sized in CLR) instead of IntPtr (dynamic sized based on bitness) for "pointer types".

The ShellExecute function has a signature of:

HINSTANCE ShellExecute(
  __in_opt  HWND hwnd,

In this case, it is important HWND is IntPtr (this is because a HWND is a "HANDLE" which is void*/"void pointer") and not long. See pinvoke.net ShellExecute as an example. (While some "solutions" are shady on pinvoke.net, it's a good place to look initially).

Happy coding.

As far as any "new syntax", I have no idea.

By using jquery ajax you can reload your page

$.ajax({
    type: "POST",
    url: "packtypeAdd.php",
    data: infoPO,
    success: function() {   
        location.reload();  
    }
});

As for now Eclipse Neon service release is available. So if someone is still encounters this trouble, just go to

Help ? Check for Updates

and install provided updates.

For my Azpen A727, the Windows driver installed correctly, so only step 3 of Mohammad's answer was necessary.

I had this problem too.

SVN doesn't do any line ending conversion, so files are committed with CRLF line endings intact. If you then use git-svn to put the project into git then the CRLF endings persist across into the git repository, which is not the state git expects to find itself in - the default being to only have unix/linux (LF) line endings checked in.

When you then check out the files on windows, the autocrlf conversion leaves the files intact (as they already have the correct endings for the current platform), however the process that decides whether there is a difference with the checked in files performs the reverse conversion before comparing, resulting in comparing what it thinks is an LF in the checked out file with an unexpected CRLF in the repository.

As far as I can see your choices are:

1. Re-import your code into a new git repository without using git-svn, this will mean line endings are converted in the intial git commit --all
2. Set autocrlf to false, and ignore the fact that the line endings are not in git's preferred style
3. Check out your files with autocrlf off, fix all the line endings, check everything back in, and turn it back on again.
4. Rewrite your repository's history so that the original commit no longer contains the CRLF that git wasn't expecting. (The usual caveats about history rewriting apply)

Footnote: if you choose option #2 then my experience is that some of the ancillary tools (rebase, patch etc) do not cope with CRLF files and you will end up sooner or later with files with a mix of CRLF and LF (inconsistent line endings). I know of no way of getting the best of both.

In addition to the answer of @Charles-Duffy, you can use winpty directly without installing/downloading anything extra. Just run winpty c:/Python27/python.exe. The utility winpty.exe can be found at Git\usr\bin. I'm using Git for Windows v2.7.1

The prebuilt binaries from @Charles-Duffy is version 0.1.1(according to the file name), while the included one is 0.2.2

Try with event.target

Contains the DOM element that issued the event. This can be the element that registered for the event or a child of it.

Not a solution to the concrete example above, but there may be many reasons why you get this error message. I got it when I accidentally added a shared module to the module declarations list and not to imports.

In app.module.ts:

import { SharedModule } from './modules/shared/shared.module';

@NgModule({
  declarations: [
     // Should not have been added here...
  ],
  imports: [
     SharedModule
  ],

Needs installed excel as it uses the Excel.Application com object.Save this as .bat file:

@if (@X)==(@Y) @end /* JScript comment
    @echo off


    cscript //E:JScript //nologo "%~f0" %*

    exit /b %errorlevel%

@if (@X)==(@Y) @end JScript comment */


var ARGS = WScript.Arguments;

var xlCSV = 6;

var objExcel = WScript.CreateObject("Excel.Application");
var objWorkbook = objExcel.Workbooks.Open(ARGS.Item(0));
objExcel.DisplayAlerts = false;
objExcel.Visible = false;

var objWorksheet = objWorkbook.Worksheets(ARGS.Item(1))
objWorksheet.SaveAs( ARGS.Item(2), xlCSV);

objExcel.Quit();

It accepts three arguments - the absolute path to the xlsx file, the sheet name and the absolute path to the target csv file:

call toCsv.bat "%cd%\Book1.xlsx" Sheet1 "%cd%\csv.csv"
