Setting JAVA_HOME directory from command line worked for me!

First:

JAVA_HOME="C:\Program Files\Java\jdk1.8.0"

Or :

export JAVA_HOME="C:\Program Files\Java\jdk1.8.0"

Then try:

mvn -version

to make sure you do not get the same error. :)

pip install -r requirements.txt for python 2.x

pip3 install -r requirements.txt for python 3.x (in case multiple versions are installed)

This is the final solution.. its works for me...!!

1) Find the whale in your system tray, and right click

2) Go to settings > Reset

3) Reset to factory defaults

I don't understand why you're doing anything with strings...

extension Date {
    var millisecondsSince1970:Int64 {
        return Int64((self.timeIntervalSince1970 * 1000.0).rounded())
    }

    init(milliseconds:Int64) {
        self = Date(timeIntervalSince1970: TimeInterval(milliseconds) / 1000)
    }
}


Date().millisecondsSince1970 // 1476889390939
Date(milliseconds: 0) // "Dec 31, 1969, 4:00 PM" (PDT variant of 1970 UTC)

Instant corresponds to time on the prime meridian (Greenwich).

Whereas LocalDateTime relative to OS time zone settings, and

cannot represent an instant without additional information such as an offset or time-zone.

I ran into a variant of this issue, here were the characteristics:

• User was able to successfully connect to a named instance, for example, connections to Server\Instance were successful
• User was unable to connect to the default instance, for example, connections to Server failed with the OP's screenshot regarding SSPI
• User was unable to connect default instance with fully qualified name, for example, connections to Server.domain.com failed (timeout)
• User was unable to connect IP address without named instance, for example, connections to 192.168.1.134 failed
• Other users not on the domain (for example, users who VPN to the network) but using domain credentials were able to successfully connect to the default instance and IP address

So after many headaches of trying to figure out why this single user couldn't connect, here are the steps we took to fix the situation:

1. Take a look at the server in the SPN list using
   setspn -l Server
   a. In our case, it said Server.domain.com
2. Add an entry to the hosts file located in C:\Windows\System32\drivers\etc\hosts (run Notepad as Administrator to alter this file). The entry we added was
   Server.domain.com Server

After this, we were able to successfully connect via SSMS to the default instance.

After 2 hours of searching, I found a way to fix it with just one line of command. You need to know the version of the package (Just search up PACKAGE version).

Command:

python3 -m pip install --pre --upgrade PACKAGE==VERSION.VERSION.VERSION

In addition of export EDITOR="code --wait", note that, with VSCode v1.47 (June 2020), those diff editors will survice a VSCode reload/restart.
See issue 99290:

with commit 1428d44, diff editors now have a chance to survive reloads and this works OK unless the diff editor on a git resource is opened as the active one:

(and commit 24f1b69 fixes that)

Simply skip the error using .values at the end.

affinity_matrix.loc['sums'] = affinity_matrix.sum(axis=0).values

Ok, I want to provide a small answer to one of the sub-questions that the OP asked that don't seem to be addressed in the existing questions. Caveat, I have not done any testing or code generation, or disassembly, just wanted to share a thought for others to possibly expound upon.

Why does the static change the performance?

The line in question: uint64_t size = atol(argv[1])<<20;

Short Answer

I would look at the assembly generated for accessing size and see if there are extra steps of pointer indirection involved for the non-static version.

Long Answer

Since there is only one copy of the variable whether it was declared static or not, and the size doesn't change, I theorize that the difference is the location of the memory used to back the variable along with where it is used in the code further down.

Ok, to start with the obvious, remember that all local variables (along with parameters) of a function are provided space on the stack for use as storage. Now, obviously, the stack frame for main() never cleans up and is only generated once. Ok, what about making it static? Well, in that case the compiler knows to reserve space in the global data space of the process so the location can not be cleared by the removal of a stack frame. But still, we only have one location so what is the difference? I suspect it has to do with how memory locations on the stack are referenced.

When the compiler is generating the symbol table, it just makes an entry for a label along with relevant attributes, like size, etc. It knows that it must reserve the appropriate space in memory but doesn't actually pick that location until somewhat later in process after doing liveness analysis and possibly register allocation. How then does the linker know what address to provide to the machine code for the final assembly code? It either knows the final location or knows how to arrive at the location. With a stack, it is pretty simple to refer to a location based one two elements, the pointer to the stackframe and then an offset into the frame. This is basically because the linker can't know the location of the stackframe before runtime.

It's probably caused by a local network connectivity issue (but also a DNS error is possible). Unfortunately HResult is generic, however you can determine the exact issue catching HttpRequestException and then inspecting InnerException: if it's a WebException then you can check the WebException.Status property, for example WebExceptionStatus.NameResolutionFailure should indicate a DNS resolution problem.

It may happen, there isn't much you can do.

What I'd suggest to always wrap that (network related) code in a loop with a try/catch block (as also suggested here for other fallible operations). Handle known exceptions, wait a little (say 1000 msec) and try again (for say 3 times). Only if failed all times then you can quit/report an error to your users. Very raw example like this:

private const int NumberOfRetries = 3;
private const int DelayOnRetry = 1000;

public static async Task<HttpResponseMessage> GetFromUrlAsync(string url) {
    using (var client = new HttpClient()) {
        for (int i=1; i <= NumberOfRetries; ++i) {
            try {
                return await client.GetAsync(url); 
            }
            catch (Exception e) when (i < NumberOfRetries) {
                await Task.Delay(DelayOnRetry);
            }
        }
    }
}

Anyone who is using pipenv (and you should!) can simply use these two commands — without having the venv activated:

rm -rf `pipenv --venv` # remove the broken venv
pipenv install --dev   # reinstall the venv from pipfile 

I found a reference that suggested adding the following to eclipse.ini

-Dswt.enable.autoScale=true
-Dswt.autoScale=200
-Dswt.autoScale.method=nearest

This doubled the size of the icons for me on Windows 10. I am using Eclipse Version: 2020-03 (4.15.0)

This is a problem related permission. Make sure that the current user has access to the folder which contains installation files.

This worked for me, inspired by Sheetal Kaul

pip uninstall matplotlib
python3 -m pip install matplotlib

I knew it installed in the wrong place when this worked:

You've already listed the most notable solutions for embedding Chromium (CEF, Chrome Frame, Awesomium). There aren't any more projects that matter.

There is still the Berkelium project (see Berkelium Sharp and Berkelium Managed), but it emebeds an old version of Chromium.

CEF is your best bet - it's fully open source and frequently updated. It's the only option that allows you to embed the latest version of Chromium. Now that Per Lundberg is actively working on porting CEF 3 to CefSharp, this is the best option for the future. There is also Xilium.CefGlue, but this one provides a low level API for CEF, it binds to the C API of CEF. CefSharp on the other hand binds to the C++ API of CEF.

Adobe is not the only major player using CEF, see other notable applications using CEF on the CEF wikipedia page.

Updating Chrome Frame is pointless since the project has been retired.

Building on @general03's answer, you can use Android's built-in style to customize the dialog quickly. You can find the dialog themes under android.R.style.Theme_DeviceDefault_Dialogxxx.

For example:

builder = new AlertDialog.Builder(this, android.R.style.Theme_DeviceDefault_Dialog_MinWidth);
builder = new AlertDialog.Builder(this, android.R.style.Theme_DeviceDefault_Dialog_NoActionBar);
builder = new AlertDialog.Builder(this, android.R.style.Theme_DeviceDefault_DialogWhenLarge);

My problem were that we were using spring securyty, and the previous page doesn't call the page using faces-redirect=true, then the page show a java warning, and the control doesn't fire the change event.

Solution: The previous page must call the page using, faces-redirect=true

VS (2013 Pro, Win 8.1) restart did it for me.

This happened to me when I was trying to push the develop branch (I am using git flow). Someone had push updates to master. to fix it I did:

git co master
git pull

Which fetched those changes. Then,

git co develop
git pull

Which didn't do anything. I think the develop branch already pushed despite the error message. Everything is up to date now and no errors.

It's not clear what type of application you're going to develop (desktop, web, console...)

The general answer, if you're developing Windows.Forms application, is use of

System.Windows.Forms.Timer class. The benefit of this is that it runs on UI thread, so it's simple just define it, subscribe to its Tick event and run your code on every 15 second.

If you do something else then windows forms (it's not clear from the question), you can choose System.Timers.Timer, but this one runs on other thread, so if you are going to act on some UI elements from the its Elapsed event, you have to manage it with "invoking" access.

So here is an idea!

Since it seemed to work somewhere else.

install python-virtualenv and optionally you can install virtualenv-wrapper (which is pretty cool to create projects and so on)

In each env, you might have different versions of eggs. In other word, you could have sqlalchemy 1 and sqlaclhemy 1.5 in two different envs and they won't conflict with each others. It seems that you have a problem with your currently installed eggs.

So here we go:

virtualenv --no-site-packages foo
source foo/bin/activate

The parameter --no-site-packages will create a virtualenv and not use the packages already installed on your computer. It's pretty much like a bare python install.

source foo/bin/activate loads the virtualenv.

It's not that really userfriendly. And that's why http://www.doughellmann.com/projects/virtualenvwrapper/ exists.

That said, you should see somthing like thant in your terminal "(foo)user@domain$:" once your virtualenv is activated. It means that you can go on!

Then you have to do.

python setup.py develop of your project. It should download and install dependencies of your project in the virtualenv located in foo. If you need to install anything else, please use pip or easy_install without using sudo. When using virtualenv, you almost never need to use sudo. Sudo will install package in your global python install while it's not required and not really desirable.

If something happens in your virtualenv, you can always delete it and create a new one. This is no big deal. No need to mess with anything. Doesn't work? start over, do pip install -U if needed, define the versions if needed and so on.

Last but not least, in the other answers, it seems that the import changed. If the new versions for flask-sqlalchemy is located somewhere else, you should update your import or install the version you used to use.

If the error you are facing is "unable to connect to remote server" as was mine, then it would benefit you to have this check as well in addition to the checks provided in the above comments.

I saw that there were 2 NUGET Package Sources from which the packages could be downloaded (within Tools->Nuget Package Manager->Packager Manager Settings). One of the Package Source's was not functioning and Nuget was trying to download from that source only.

I wanted to ask the same question. Here is my current solution to obtain a string like this: 2013-02-07 09:24:40.749355372 I am not sure if there is a more straight forward solution than this, but at least the string format is freely configurable with this approach.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>

#define NANO 1000000000L

// buf needs to store 30 characters
int timespec2str(char *buf, uint len, struct timespec *ts) {
    int ret;
    struct tm t;

    tzset();
    if (localtime_r(&(ts->tv_sec), &t) == NULL)
        return 1;

    ret = strftime(buf, len, "%F %T", &t);
    if (ret == 0)
        return 2;
    len -= ret - 1;

    ret = snprintf(&buf[strlen(buf)], len, ".%09ld", ts->tv_nsec);
    if (ret >= len)
        return 3;

    return 0;
}

int main(int argc, char **argv) {
    clockid_t clk_id = CLOCK_REALTIME;
    const uint TIME_FMT = strlen("2012-12-31 12:59:59.123456789") + 1;
    char timestr[TIME_FMT];

    struct timespec ts, res;
    clock_getres(clk_id, &res);
    clock_gettime(clk_id, &ts);

    if (timespec2str(timestr, sizeof(timestr), &ts) != 0) {
        printf("timespec2str failed!\n");
        return EXIT_FAILURE;
    } else {
        unsigned long resol = res.tv_sec * NANO + res.tv_nsec;
        printf("CLOCK_REALTIME: res=%ld ns, time=%s\n", resol, timestr);
        return EXIT_SUCCESS;
    }
}

output:

Expressions like "difference in days" are never as simple as they seem. If you have the following dates:

d1: 2011-10-15 23:59:00
d1: 2011-10-16 00:01:00

the difference in time is 2 minutes, should the "difference in days" be 1 or 0? Similar issues arise for any expression of the difference in months, years or whatever since years, months and days are of different lengths and different times (e.g. the day that daylight saving starts is 1 hour shorter than usual and two hours shorter than the day that it ends).

Here is a function for a difference in days that ignores the time, i.e. for the above dates it returns 1.

/*
   Get the number of days between two dates - not inclusive.

   "between" does not include the start date, so days
   between Thursday and Friday is one, Thursday to Saturday
   is two, and so on. Between Friday and the following Friday is 7.

   e.g. getDaysBetweenDates( 22-Jul-2011, 29-jul-2011) => 7.

   If want inclusive dates (e.g. leave from 1/1/2011 to 30/1/2011),
   use date prior to start date (i.e. 31/12/2010 to 30/1/2011).

   Only calculates whole days.

   Assumes d0 <= d1
*/
function getDaysBetweenDates(d0, d1) {

  var msPerDay = 8.64e7;

  // Copy dates so don't mess them up
  var x0 = new Date(d0);
  var x1 = new Date(d1);

  // Set to noon - avoid DST errors
  x0.setHours(12,0,0);
  x1.setHours(12,0,0);

  // Round to remove daylight saving errors
  return Math.round( (x1 - x0) / msPerDay );
}

This can be more concise:

/*  Return number of days between d0 and d1._x000D_
**  Returns positive if d0 < d1, otherwise negative._x000D_
**_x000D_
**  e.g. between 2000-02-28 and 2001-02-28 there are 366 days_x000D_

In my case, I was trying to parse an empty JSON:

JSON.parse(stringifiedJSON);

In other words, what happened was the following:

JSON.parse("");

This helped for me

this.myGridview.Columns[0].Visible = false;

Here 0 is the column index i want to hide.

I guess this can be due to many things. In my case it was having "WHERE id IN" condition in my query and I was setting IDs separated by dash as a string using setString method on PreparedStatement.

Not sure if there is better way to do this but I just added placeholder in my statement and replaced it by values on my own.

You can abstract the time measuring mechanism and have each callable's run time measured with minimal extra code, just by being called through a timer structure. Plus, at compile time you can parametrize the timing type (milliseconds, nanoseconds etc).

^{Thanks to the review by Loki Astari and the suggestion to use variadic templates. This is why the forwarded function call.}

#include <iostream>
#include <chrono>

template<typename TimeT = std::chrono::milliseconds>
struct measure
{
    template<typename F, typename ...Args>
    static typename TimeT::rep execution(F&& func, Args&&... args)

int main() {
    std::cout << measure<>::execution(functor(dummy)) << std::endl;

Demo

According to the comment by Howard Hinnant it's best not to escape out of the chrono system until we have to. So the above class could give the user the choice to call count manually by providing an extra static method (shown in C++14)

template<typename F, typename ...Args>
static auto duration(F&& func, Args&&... args)
{
    auto start = std::chrono::steady_clock::now();
    std::forward<decltype(func)>(func)(std::forward<Args>(args)...);
    return std::chrono::duration_cast<TimeT>(std::chrono::steady_clock::now()-start);
} 

// call .count() manually later when needed (eg IO)
auto avg = (measure<>::duration(func) + measure<>::duration(func)) / 2.0;

and be most useful for clients that

"want to post-process a bunch of durations prior to I/O (e.g. average)"

The complete code can be found here. My attempt to build a benchmarking tool based on chrono is recorded here.

If C++17's std::invoke is available, the invocation of the callable in execution could be done like this :

invoke(forward<decltype(func)>(func), forward<Args>(args)...);

to provide for callables that are pointers to member functions.

I got this error while running unit tests on inmemory caching I was setting up. It flooded the cache. After invalidating the cache and restarting the VM, it worked fine.

while running web applications Most of us will get this Exception. When you got this error you have place .class files in proper folder.

In web applications all .class files should sit in WEB-INF\Classes folder. if you are running web app in Eclipse please follow the steps

Step 1: Right click on Project folder and Select Properties Step 2: Click on "Java Build Path" you will see different tabs like "source" , "projects", "libraries" etc Step 3: select Source folder. under this you will see your project details Step 4: in the "Source" folder you will see Default Output Folder option. here you have to give the classes folder under WEB-INF. just give the path like projectname/WebContent/WEB-INF/classes the structure depends on your application please do remember here you no need to create "classes" folder. Eclipse will create it for you. Step 5: click on "OK" and do the project clean and Build. that's it your app will run now.

SOLVED

Well, you could just divide by 1,000,000,000:

long elapsedTime = end - start;
double seconds = (double)elapsedTime / 1_000_000_000.0;

If you use TimeUnit to convert, you'll get your result as a long, so you'll lose decimal precision but maintain whole number precision.

Unless I'm badly mistaken libmagic or -lmagic is not the same library as ImageMagick. You state that you want ImageMagick.

ImageMagick comes with a utility to supply all appropriate options to the compiler.

Ex:

g++ program.cpp `Magick++-config --cppflags --cxxflags --ldflags --libs` -o "prog"

Be careful, if you need precision higher than milliseconds!

.NET (v4.6) methods (e.g. FromUnixTimeMilliseconds) don't provide this precision.

AddSeconds and AddMilliseconds also cut off the microseconds in the double.

These versions have high precision:

    return new DateTime(unixStart.Ticks + unixTimeStampInTicks, System.DateTimeKind.Utc);

Have you seen this already? The cause seems to be a very old libpam on one of the sides, probably on that customer.

From Visual Studio 2015 consider to use out of the box Memory Usage diagnostic tool to collect and analyze memory usage data.

The Memory Usage tool lets you take one or more snapshots of the managed and native memory heap to help understand the memory usage impact of object types.

The usual error is one tries to put Content-Type: {multipart/form-data} into the header of the post request. That will fail, it is best to let Postman do it for you. For example:

Create a WebViewClient, and override the shouldOverrideUrlLoading method.

webview.setWebViewClient(new WebViewClient() {
    public boolean shouldOverrideUrlLoading(WebView view, String url){
        // do your handling codes here, which url is the requested url
        // probably you need to open that url rather than redirect:
        view.loadUrl(url);
        return false; // then it is not handled by default action
   }
});

For me, I had encountered this error when invoking a webservice call, make sure that the site has a valid ssl, i.e the logo on the side of the url is checked, otherwise need to add the certificate to trusted key store in your machine

Starting from Java 9, there is a new utility method allowing to create an immutable entry which is Map#entry(Object, Object).

Here is a simple example:

Entry<String, String> entry = Map.entry("foo", "bar");

As it is immutable, calling setValue will throw an UnsupportedOperationException. The other limitations are the fact that it is not serializable and null as key or value is forbidden, if it is not acceptable for you, you will need to use AbstractMap.SimpleImmutableEntry or AbstractMap.SimpleEntry instead.

NB: If your need is to create directly a Map with 0 to up to 10 (key, value) pairs, you can instead use the methods of type Map.of(K key1, V value1, ...).

I don´t know how to do it using code, but for those who don't mind using a plugin. This is a great one that works for me:

https://es.wordpress.org/plugins/permalink-manager/

My trick is using an attribute selector. Attributes are easier to set up by javascript.

css

.class{ /*normal css... */}
.class[special]:after{ content: 'what you want'}

javascript

  function setSpecial(id){ document.getElementById(id).setAttribute('special', '1'); }

html

<element id='x' onclick="setSpecial(this.id)"> ...  

I had problems with most of the tools in other answers as they are all very outdated.

If you need a solution that will "just work", pack a bare-bones version of php with your project in a WinRar SFX archive, set it to extract everything to a temporary directory and execute php your_script.php.

To run a basic script, the only files required are php.exe and php5.dll (or php5ts.dll depending on version).

To add extensions, pack them along with a php.ini file:

[PHP]
extension_dir = "."
extension=php_curl.dll
extension=php_xxxx.dll
...

Given your edited problem description, I'd suggest using COALESCE() instead of that unwieldy CASE expression:

SELECT FullName
FROM (
  SELECT COALESCE(LastName+', '+FirstName, FirstName) AS FullName
  FROM customers
) c
GROUP BY FullName;

I prepared a library based on links posted in this thread. It uses the examples from MSDN and CodeProject. Thanks to James.

I also made modifications advised by Joel Mueller.

Code is here:

https://github.com/dermeister0/LockFreeSessionState

HashTable module:

Install-Package Heavysoft.LockFreeSessionState.HashTable

ScaleOut StateServer module:

Install-Package Heavysoft.LockFreeSessionState.Soss

Custom module:

Install-Package Heavysoft.LockFreeSessionState.Common

If you want to implement support of Memcached or Redis, install this package. Then inherit the LockFreeSessionStateModule class and implement abstract methods.

The code is not tested on production yet. Also need to improve error handling. Exceptions are not caught in current implementation.

Some lock-free session providers using Redis:

• https://github.com/angieslist/AL-Redis (Suggested by gregmac in this thread.)
• https://github.com/welegan/RedisSessionProvider (NuGet: RedisSessionProvider)
• https://github.com/efaruk/playground/tree/master/UnlockedStateProvider (NuGet: UnlockedStateProvider.Redis)

If I understand correctly, you can use the module operator for this. For example, in Java (and a lot of other languages), you could do:

//j is a multiple of four if
j % 4 == 0

The module operator performs division and gives you the remainder.

If it's an object method, you need to pass the object to CallObjectMethod:

jobject result = env->CallObjectMethod(obj, messageMe, jstr);

What you were doing was the equivalent of jstr.messageMe().

Since your is a void method, you should call:

env->CallVoidMethod(obj, messageMe, jstr);

If you want to return a result, you need to change your JNI signature (the ()V means a method of void return type) and also the return type in your Java code.

I think what you're trying to do is wrap loooooooooooooong words or URLs so they don't push the size of the table out. (I've just been trying to do the same thing!)

You can do this easily with a DIV by giving it the style word-wrap: break-word (and you may need to set its width, too).

div {
    word-wrap: break-word;         /* All browsers since IE 5.5+ */
    overflow-wrap: break-word;     /* Renamed property in CSS3 draft spec */
    width: 100%;
}

However, for tables, you must either wrap the content in a DIV (or other block tag) or apply: table-layout: fixed. This means the columns widths are no longer fluid, but are defined based on the widths of the columns in the first row only (or via specified widths). Read more here.

Sample code:

table {
    table-layout: fixed;
    width: 100%;
}

table td {
    word-wrap: break-word;         /* All browsers since IE 5.5+ */
    overflow-wrap: break-word;     /* Renamed property in CSS3 draft spec */
}

Hope that helps somebody.

For your design, it is common practice to use divs rather than a table. This way, your layout will be more maintainable and changeable through proper styling. It does take some getting used to, but it will help you a ton in the long run and you will learn a lot about how styling works. However, I will provide you with a solution to the problem at hand.

In your stylesheets you have margins and padding set to 0 pixels. This overrides your align="center" attribute. I would recommend taking these settings out of your CSS as you don't normally want all of your elements to be affected in this manner. If you already know what's going on in the CSS, and you want to keep it that way, then you have to apply a style to your table to override the previous sets. You could either give the table a class or you can put the style inline with the HTML. Here are the two options:

1. With a class:

   <table class="centerTable"></table>

In your style.css file you would have something like this:

.centerTable { margin: 0px auto; }

2. Inline with your HTML:

   <table style="margin: 0px auto;"></table>

If you decide to wipe out the margins and padding being set to 0px, then you can keep align="center" on your <td> tags for whatever column you wish to align.

Call your hosting company and either have them set up regular log backups or set the recovery model to simple. I'm sure you know what informs the choice, but I'll be explicit anyway. Set the recovery model to full if you need the ability to restore to an arbitrary point in time. Either way the database is misconfigured as is.

I had this error because I registered the wrong class in this line of code:

New answer to old question

None of the existing answers to this old question address the real problem.

The real problem was that xs:complexType cannot directly have a xs:extension as a child in XSD. The fix is to use xs:simpleContent first. Details follow...

Your XML,

<price currency="euros">20000.00</price>

will be valid against either of the following corrected XSDs:

Locally defined attribute type

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:element name="price">
    <xs:complexType>
      <xs:simpleContent>
        <xs:extension base="xs:decimal">
          <xs:attribute name="currency">
            <xs:simpleType>
              <xs:restriction base="xs:string">
                <xs:enumeration value="pounds" />
                <xs:enumeration value="euros" />
                <xs:enumeration value="dollars" />
              </xs:restriction>
            </xs:simpleType>
          </xs:attribute>
        </xs:extension>
      </xs:simpleContent>
    </xs:complexType>
  </xs:element>
</xs:schema>

Globally defined attribute type

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:simpleType name="currencyType">
    <xs:restriction base="xs:string">
      <xs:enumeration value="pounds" />
      <xs:enumeration value="euros" />
      <xs:enumeration value="dollars" />
    </xs:restriction>
  </xs:simpleType>

  <xs:element name="price">
    <xs:complexType>
      <xs:simpleContent>
        <xs:extension base="xs:decimal">
          <xs:attribute name="currency" type="currencyType"/>
        </xs:extension>
      </xs:simpleContent>
    </xs:complexType>
  </xs:element>
</xs:schema>

Notes

• As commented by @Paul, these do change the content type of price from xs:string to xs:decimal, but this is not strictly necessary and was not the real problem.
• As answered by @user998692, you could separate out the definition of currency, and you could change to xs:decimal, but this too was not the real problem.

The real problem was that xs:complexType cannot directly have a xs:extension as a child in XSD; xs:simpleContent is needed first.

A related matter (that wasn't asked but may have confused other answers):

How could price be restricted given that it has an attribute?

In this case, a separate, global definition of priceType would be needed; it is not possible to do this with only local type definitions.

    <xs:restriction base="xs:decimal">  
      <xs:minInclusive value="0.00"/>  
      <xs:maxInclusive value="99999.99"/>  
    </xs:restriction>  
  </xs:simpleType>

  <xs:element name="price">
    <xs:complexType>
      <xs:simpleContent>
        <xs:extension base="priceType">
          <xs:attribute name="currency">
            <xs:simpleType>
              <xs:restriction base="xs:string">
                <xs:enumeration value="pounds" />
                <xs:enumeration value="euros" />
                <xs:enumeration value="dollars" />
              </xs:restriction>
            </xs:simpleType>
          </xs:attribute>
        </xs:extension>
      </xs:simpleContent>
    </xs:complexType>
  </xs:element>
</xs:schema>

This is pretty old, but I ran across this question via Google, so perhaps this solution might be useful to others.

function GetObjectName(myObject){
    var objectName=JSON.stringify(myObject).match(/"(.*?)"/)[1];
    return objectName;
}

It just uses the browser's JSON parser and regex without cluttering up the DOM or your object too much.

well , you can create and also can subclass the UIStoryBoardSegue . subclassing is mostly used for giving custom transition animation.

you can see video of wwdc 2011 introducing StoryBoard. its available in youtube also.

http://developer.apple.com/library/ios/#documentation/UIKit/Reference/UIStoryboardSegue_Class/Reference/Reference.html#//apple_ref/occ/cl/UIStoryboardSegue

You can just do:

git checkout --orphan assets
cp /where/image/currently/located/on/machine/diagram.png .
git add .
git commit -m 'Added diagram'
git push -u origin assets

Then you can just reference it in the README file like so:

![diagram](diagram.png)

Here's how you convert numbers to strings, and join strings to other things (it's weird):

>> ['the number is ' num2str(15) '.']
ans =
the number is 15.

You could simplify the above equations using the following:

boolean flag = sqlInt != 0;

If the int representation (sqlInt) of the boolean is 0 (false), the boolean (flag) will be false, otherwise it will be true.

Concise code is always nicer to work with :)

First off, I think mplot3D worked a bit differently in matplotlib version 0.99 than it does in the current version of matplotlib.

Which version are you using? (Try running: python -c 'import matplotlib; print matplotlib."__version__")

I'm guessing you're running version 0.99, in which case you'll need to either use a slightly different syntax or update to a more recent version of matplotlib.

If you're running version 0.99, try doing this instead of using using the projection keyword argument:

import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import axes3d, Axes3D #<-- Note the capitalization! 
fig = plt.figure()

ax = Axes3D(fig) #<-- Note the difference from your original code...

X, Y, Z = axes3d.get_test_data(0.05)
cset = ax.contour(X, Y, Z, 16, extend3d=True)
ax.clabel(cset, fontsize=9, inline=1)
plt.show()

This should work in matplotlib 1.0.x, as well, not just 0.99.

I fixed this using pycharm. At the bottom of pycharm you can see file encoding. I noticed that it is UT-8. I changed it to US-ASCII

There are two ways you could do this. Either create your own custom exception class to represent a divide by zero error or throw the same type of exception the java runtime would throw in this situation.

Define custom exception

public class DivideByZeroException() extends ArithmeticException {
}

Then in your code you would check for a divide by zero and throw this exception:

if (divisor == 0) throw new DivideByZeroException();

Throw ArithmeticException

Add to your code the check for a divide by zero and throw an arithmetic exception:

if (divisor == 0) throw new java.lang.ArithmeticException("/ by zero");

Additionally, you could consider throwing an illegal argument exception since a divisor of zero is an incorrect argument to pass to your setKp() method:

if (divisor == 0) throw new java.lang.IllegalArgumentException("divisor == 0");

Try starting with the Percona wizard and comparing their recommendations against your current settings one by one. Don't worry there aren't as many applicable settings as you might think.

Everyone points to key_buffer_size first which you have addressed. With 96GB memory I'd be wary of any tiny default value (likely to be only 96M!).

The easiest way is to use the `` feature in Perl. This will execute what is inside and return what was printed to stdout:

 my $pid = 5892;
 my $var = `top -H -p $pid -n 1 | grep myprocess | wc -l`;
 print "not = $var\n";

This should do it.

If I am not mistaken, it will be onunload event.

"Occurs when the application is about to be unloaded." - MSDN

I just want to build upon Serpens answer and add the line:

logger.setLevel('DEBUG')

This will allow you to chose what level of message gets logged.

For example in Serpens example,

logger.info('Info message')

Will not get recorded as it defaults to only recording Warnings and above.

More about levels used can be read about here

We tried everything listed so far and it still failed. The error also mentioned

(default-war) on project utilsJava: Error assembling WAR: webxml attribute is required

The solution that finally fixed it was adding this to POM:

<failOnMissingWebXml>false</failOnMissingWebXml>

As mentioned here Error assembling WAR - webxml attribute is required

Our POM now contains this:

<plugin>
<inherited>true</inherited>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>${maven-war-plugin.version}</version>

<warName>${project.artifactId}</warName>
<attachClasses>true</attachClasses>
</configuration>
</plugin>  

REDUX

You can also use react-router-redux which has goBack() and push().

Here is a sampler pack for that:

In your app's entry point, you need ConnectedRouter, and a sometimes tricky connection to hook up is the history object. The Redux middleware listens to history changes:

import React from 'react'
import { render } from 'react-dom'
import { ApolloProvider } from 'react-apollo'
import { Provider } from 'react-redux'
import { ConnectedRouter } from 'react-router-redux'
import client from './components/apolloClient'
import store, { history } from './store'
import Routes from './Routes'
import './index.css'

render(
  <ApolloProvider client={client}>
    <Provider store={store}>
      <ConnectedRouter history={history}>
        <Routes />
      </ConnectedRouter>
    </Provider>
  </ApolloProvider>,
  document.getElementById('root'),
)

I will show you a way to hook up the history. Notice how the history is imported into the store and also exported as a singleton so it can be used in the app's entry point:

import { createStore, applyMiddleware, compose } from 'redux'
import { routerMiddleware } from 'react-router-redux'
import thunk from 'redux-thunk'
import createHistory from 'history/createBrowserHistory'
import rootReducer from './reducers'

export const history = createHistory()

const initialState = {}
const enhancers = []
const middleware = [thunk, routerMiddleware(history)]

if (process.env.NODE_ENV === 'development') {
  const { devToolsExtension } = window
  if (typeof devToolsExtension === 'function') {
    enhancers.push(devToolsExtension())
  }
}

const composedEnhancers = compose(applyMiddleware(...middleware), ...enhancers)
const store = createStore(rootReducer, initialState, composedEnhancers)

export default store

The above example block shows how to load the react-router-redux middleware helpers which complete the setup process.

I think this next part is completely extra, but I will include it just in case someone in the future finds benefit:

import { combineReducers } from 'redux'
import { routerReducer as routing } from 'react-router-redux'

export default combineReducers({
  routing, form,
})

I use routerReducer all the time because it allows me to force reload Components that normally do not due to shouldComponentUpdate. The obvious example is when you have a Nav Bar that is supposed to update when a user presses a NavLink button. If you go down that road, you will learn that Redux's connect method uses shouldComponentUpdate. With routerReducer, you can use mapStateToProps to map routing changes into the Nav Bar, and this will trigger it to update when the history object changes.

Like this:

const mapStateToProps = ({ routing }) => ({ routing })

export default connect(mapStateToProps)(Nav)

Forgive me while I add some extra keywords for people: if your component isn't updating properly, investigate shouldComponentUpdate by removing the connect function and see if it fixes the problem. If so, pull in the routerReducer and the component will update properly when the URL changes.

In closing, after doing all that, you can call goBack() or push() anytime you want!

Try it now in some random component:

1. Import in connect()
2. You don't even need mapStateToProps or mapDispatchToProps
3. Import in goBack and push from react-router-redux
4. Call this.props.dispatch(goBack())
5. Call this.props.dispatch(push('/sandwich'))
6. Experience positive emotion

you can write multiple lines in case of different minutes, for example you want to run at 10:01 AM and 2:30 PM

1 10 * * * php -f /var/www/package/index.php controller function

30 14 * * * php -f /var/www/package/index.php controller function

but the following is the best solution for running cron multiple times in a day as minutes are same, you can mention hours like 10,30 .

30 10,14 * * * php -f /var/www/package/index.php controller function

Expanding on Tony's answer, and also answering Dhaval Ptl's question, to get the true accordion effect and only allow one row to be expanded at a time, an event handler for show.bs.collapse can be added like so:

$('.collapse').on('show.bs.collapse', function () {
    $('.collapse.in').collapse('hide');
});

I modified his example to do this here: http://jsfiddle.net/QLfMU/116/

Because break cannot be used to break out of an if - it can only break out of loops. That's the way Python (and most other languages) are specified to behave.

What are you trying to do? Perhaps you should use sys.exit() or return instead?

I have some vague recollections of Oracle databases needing a bit of fiddling when you reboot for the first time after installing the database. However, you haven't given us enough information to work on. To start with:

• What code are you using to connect to the database?
• It's not clear whether the database instance has been started. Can you connect to the database using sqlplus / as sysdba from within the VM?
• What has been written to the listener.log file (in %ORACLE_HOME%\network\log) since the last reboot?

EDIT: I've now been able to come up with a scenario which generates the same error message you got. It looks to me like the database you're attempting to connect to has not been started up. The example I present below uses Oracle XE on Linux, but I don't think this makes a significant difference.

First, let us confirm that the database is shut down:

$ sqlplus / as sysdba

SQL*Plus: Release 10.2.0.1.0 - Production on Sat Jul 17 18:16:43 2010

Copyright (c) 1982, 2005, Oracle.  All rights reserved.

Connected to an idle instance.

It's the text Connected to an idle instance that tells us that the database is shut down.

Using sqlplus / as sysdba connects us to the database as SYS without needing a password, but it only works on the same machine as the database itself. In your case, you'd need to run this inside the virtual machine. SYS has permission to start up and shut down the database, and to connect to it when it is shut down, but normal users don't have these permissions.

Now let us disconnect and try reconnecting as a normal user, one that does not have permission to startup/shutdown the database nor connect to it when it is down:

SQL> exit

That's the error message you've been getting.

Now, let's start the database up:

We're in.

I hadn't seen an ORA-12505 error before because I don't normally connect to an Oracle database by entering the entire connection string on the command line. This is likely to be similar to how you are attempting to connect to the database. Usually, I either connect to a local database, or connect to a remote database by using a TNS name (these are listed in the tnsnames.ora file, in %ORACLE_HOME%\network\admin). In both of these cases you get a different error message if you attempt to connect to a database that has been shut down.

If the above doesn't help you (in particular, if the database has already been started, or you get errors starting up the database), please let us know.

EDIT 2: it seems the problems you were having were indeed because the database hadn't been started. It also appears that your database isn't configured to start up when the service starts. It is possible to get the database to start up when the service is started, and to shut down when the service is stopped. To do this, use the Oracle Administration Assistant for Windows, see here.

If you want to individually generate ddl for each object,

Queries are:

--GENERATE DDL FOR ALL USER OBJECTS

--1. FOR ALL TABLES

SELECT DBMS_METADATA.GET_DDL('TABLE', TABLE_NAME) FROM USER_TABLES;

--2. FOR ALL INDEXES

SELECT DBMS_METADATA.GET_DDL('INDEX', INDEX_NAME) FROM USER_INDEXES WHERE INDEX_TYPE ='NORMAL';

--3. FOR ALL VIEWS

SELECT DBMS_METADATA.GET_DDL('VIEW', VIEW_NAME) FROM USER_VIEWS;

OR

SELECT TEXT FROM USER_VIEWS

--4. FOR ALL MATERILIZED VIEWS

SELECT QUERY FROM USER_MVIEWS

--5. FOR ALL FUNCTION

SELECT DBMS_METADATA.GET_DDL('FUNCTION', OBJECT_NAME) FROM USER_PROCEDURES WHERE OBJECT_TYPE = 'FUNCTION'

===============================================================================================

GET_DDL Function doesnt support for some object_type like LOB,MATERIALIZED VIEW, TABLE PARTITION

SO, Consolidated query for generating DDL will be:

SELECT OBJECT_TYPE, OBJECT_NAME,DBMS_METADATA.GET_DDL(OBJECT_TYPE, OBJECT_NAME, OWNER)
  FROM ALL_OBJECTS 
  WHERE (OWNER = 'XYZ') AND OBJECT_TYPE NOT IN('LOB','MATERIALIZED VIEW', 'TABLE PARTITION') ORDER BY OBJECT_TYPE, OBJECT_NAME;

You will need to specify TimeSeries in Excel to be plotted. Have a look at this

Open the pom.xml file.

under the project tag add <dependencies> as another tag, and google for the Maven dependencies. I used this to search.

So after getting the dependency create another tag dependency inside <dependencies> tag.

So ultimately it will look something like this.

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Straight from the React docs:

fetch('https://mywebsite.com/endpoint/', {
  method: 'POST',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    firstParam: 'yourValue',
    secondParam: 'yourOtherValue',
  })
})

(This is posting JSON, but you could also do, for example, multipart-form.)

You could consider using an external tool like ffmpeg to merge the images into a movie (see answer here) or you could try to use OpenCv to combine the images into a movie like the example here.

I'm attaching below a code snipped I used to combine all png files from a folder called "images" into a video.

import cv2
import os

image_folder = 'images'
video_name = 'video.avi'

images = [img for img in os.listdir(image_folder) if img.endswith(".png")]
frame = cv2.imread(os.path.join(image_folder, images[0]))
height, width, layers = frame.shape

video = cv2.VideoWriter(video_name, 0, 1, (width,height))

for image in images:
    video.write(cv2.imread(os.path.join(image_folder, image)))

cv2.destroyAllWindows()
video.release()

If you must work with raw arrays and not ArrayList then Arrays has what you need. If you look at the source code, these are the absolutely best ways to get a copy of an array. They do have a good bit of defensive programming because the System.arraycopy() method throws lots of unchecked exceptions if you feed it illogical parameters.

You can use either Arrays.copyOf() which will copy from the first to Nth element to the new shorter array.

public static <T> T[] copyOf(T[] original, int newLength)

Copies the specified array, truncating or padding with nulls (if necessary) so the copy has the specified length. For all indices that are valid in both the original array and the copy, the two arrays will contain identical values. For any indices that are valid in the copy but not the original, the copy will contain null. Such indices will exist if and only if the specified length is greater than that of the original array. The resulting array is of exactly the same class as the original array.

2770
2771    public static <T,U> T[] More ...copyOf(U[] original, int newLength, Class<? extends T[]> newType) {
2772        T[] copy = ((Object)newType == (Object)Object[].class)
2773            ? (T[]) new Object[newLength]
2774            : (T[]) Array.newInstance(newType.getComponentType(), newLength);
2775        System.arraycopy(original, 0, copy, 0,
2776                         Math.min(original.length, newLength));
2777        return copy;
2778    }

or Arrays.copyOfRange() will also do the trick:

public static <T> T[] copyOfRange(T[] original, int from, int to)

Copies the specified range of the specified array into a new array. The initial index of the range (from) must lie between zero and original.length, inclusive. The value at original[from] is placed into the initial element of the copy (unless from == original.length or from == to). Values from subsequent elements in the original array are placed into subsequent elements in the copy. The final index of the range (to), which must be greater than or equal to from, may be greater than original.length, in which case null is placed in all elements of the copy whose index is greater than or equal to original.length - from. The length of the returned array will be to - from. The resulting array is of exactly the same class as the original array.

3035    public static <T,U> T[] More ...copyOfRange(U[] original, int from, int to, Class<? extends T[]> newType) {
3036        int newLength = to - from;
3037        if (newLength < 0)
3038            throw new IllegalArgumentException(from + " > " + to);
3039        T[] copy = ((Object)newType == (Object)Object[].class)
3040            ? (T[]) new Object[newLength]
3041            : (T[]) Array.newInstance(newType.getComponentType(), newLength);
3042        System.arraycopy(original, from, copy, 0,
3043                         Math.min(original.length - from, newLength));
3044        return copy;
3045    }

As you can see, both of these are just wrapper functions over System.arraycopy with defensive logic that what you are trying to do is valid.

System.arraycopy is the absolute fastest way to copy arrays.

Because you don't close your Scanner

in.close();

update: nowadays we have mobile and custom keyboards and we cannot continue trusting these arbitrary key codes such as 13 and 186. in other words, stop using event.which/event.keyCode and start using event.key:

if (event.key === "Enter" || event.key === "ArrowUp" || event.key === "ArrowDown")

you can do it by following way too ..

create table #test (a int, b char(1))

select * From #test

exec tempdb..sp_columns '#test'

It's as easy as the following:

info_1 = "one piece of info"
info_2 = "another piece"
vars = (info_1, info_2)
# 'vars' is now a tuple with the values ("info_1", "info_2")

However, tuples in Python are immutable, so you cannot append variables to a tuple once it is created.

If the goal is to build an API that allow you to access your models in JSON format I recommend you to use the django-restframework that is an enormously popular package within the Django community to achieve this type of tasks.

• Django Rest Framework Website
• Github

It include useful features such as Pagination, Defining Serializers, Nested models/relations and more. Even if you only want to do minor Javascript tasks and Ajax calls I would still suggest you to build a proper API using the Django Rest Framework instead of manually defining the JSON response.

Sometimes size "picks the wrong one" and returns a hash (which is what count would do)

In that case, use length to get an integer instead of hash.

We have found that adding the Apptentive cocoa pod to an existing Xcode project may potentially not include some of our required frameworks.

Check your linker flags:

Target > Build Settings > Other Linker Flags 

You should see -lApptentiveConnect listed as a linker flag:

... -ObjC -lApptentiveConnect ... 

You should also see our required Frameworks listed:

• Accelerate
• CoreData
• CoreText
• CoreGraphics
• CoreTelephony
• Foundation
• QuartzCore
• StoreKit
• SystemConfiguration

• UIKit

  -ObjC -lApptentiveConnect -framework Accelerate -framework CoreData -framework CoreGraphics -framework CoreText -framework Foundation -framework QuartzCore -framework SystemConfiguration -framework UIKit -framework CoreTelephony -framework StoreKit  

is this for display purposes? if so you really should consider separating your display form your logic and use style sheets for formatting. being server side php should really allow providing and accepting data. while you could surely use php to do what you are asking I am a very firm believer in keeping display and logic with as much separation as possible. with styles you can do all of your typesetting.

give output class wrappers and style accordingly.

The assignment does not remove the newline characters, it's actually the echo doing this. You need simply put quotes around the string to maintain those newlines:

echo "$testvar"

This will give the result you want. See the following transcript for a demo:

pax> cat num1.txt ; x=$(cat num1.txt)
line 1
line 2

pax> echo $x ; echo '===' ; echo "$x"
line 1 line 2
===
line 1
line 2

The reason why newlines are replaced with spaces is not entirely to do with the echo command, rather it's a combination of things.

When given a command line, bash splits it into words according to the documentation for the IFS variable:

IFS: The Internal Field Separator that is used for word splitting after expansion ... the default value is <space><tab><newline>.

That specifies that, by default, any of those three characters can be used to split your command into individual words. After that, the word separators are gone, all you have left is a list of words.

Combine that with the echo documentation (a bash internal command), and you'll see why the spaces are output:

echo [-neE] [arg ...]: Output the args, separated by spaces, followed by a newline.

When you use echo "$x", it forces the entire x variable to be a single word according to bash, hence it's not split. You can see that with:

pax> function count {
...>    echo $#
...> }
pax> count 1 2 3
3
pax> count a b c d
4
pax> count $x
4
pax> count "$x"
1

Here, the count function simply prints out the number of arguments given. The 1 2 3 and a b c d variants show it in action.

Then we try it with the two variations on the x variable. The one without quotes shows that there are four words, "test", "1", "test" and "2". Adding the quotes makes it one single word "test 1\ntest 2".

Surround the script call with "", generally it's good practices to do so with filepath.

"C:\Program Files"

Although for this particular name you probably should use environment variable like this :

"%ProgramFiles%\batch.cmd"

or for 32 bits program on 64 bit windows :

"%ProgramFiles(x86)%\batch.cmd"

This may fit better as a comment but I don't have enough reputation, so I put it here.
It worth mentioning that the load() function will retain the object name that was originally saved no matter how you name the .Rdata file.

Please check the name of the data.frame object used in the save() function. If you were using RStudio, you could check the upper right panel, Global Environment-Data, to find the name of the data you load.

This one will preserve rectangular shape, so that subsequent transposes will get the right result:

import itertools
def transpose(list_of_lists):
  return list(itertools.izip_longest(*list_of_lists,fillvalue=' '))

I encountered the write:errno=104 attempting to test connecting to an SSL-enabled RabbitMQ broker port with openssl s_client.

The issue turned out to be simply that the user RabbitMQ was running as did not have read permissions on the certificate file. There was little-to-no useful logging in RabbitMQ.

1. GET method is use to send the less sensitive data whereas POST method is use to send the sensitive data.
2. Using the POST method you can send large amount of data compared to GET method.
3. Data sent by GET method is visible in browser header bar whereas data send by POST method is invisible.

Just to supplement the answers already given, if you also want to NOT minify/obfuscate/concatenate SOME files while still allowing full bundling and minification for other files the best option is to go with a custom renderer which will read the contents of a particular bundle(s) and render the files in the page rather than render the bundle's virtual path. I personally required this because IE 9 was $*%@ing the bed when my CSS files were being bundled even with minification turned off.

Thanks very much to this article, which gave me the starting point for the code which I used to create a CSS Renderer which would render the files for the CSS but still allow the system to render my javascript files bundled/minified/obfuscated.

Created the static helper class:

using System;
using System.Text;
using System.Web;
using System.Web.Mvc;
using System.Web.Optimization;

namespace Helpers
{
  public static class OptionalCssBundler
  {
    const string CssTemplate = "<link href=\"{0}\" rel=\"stylesheet\" type=\"text/css\" />";

    public static MvcHtmlString ResolveBundleUrl(string bundleUrl, bool bundle)
    {
      return bundle ? BundledFiles(BundleTable.Bundles.ResolveBundleUrl(bundleUrl)) : UnbundledFiles(bundleUrl);
    }

    private static MvcHtmlString BundledFiles(string bundleVirtualPath)
    {
      return new MvcHtmlString(string.Format(CssTemplate, bundleVirtualPath));
    }

    private static MvcHtmlString UnbundledFiles(string bundleUrl)
    {
      var bundle = BundleTable.Bundles.GetBundleFor(bundleUrl);

      StringBuilder sb = new StringBuilder();
      var urlHelper = new UrlHelper(HttpContext.Current.Request.RequestContext);

      foreach (BundleFile file in bundle.EnumerateFiles(new BundleContext(new HttpContextWrapper(HttpContext.Current), BundleTable.Bundles, bundleUrl)))
      {
        sb.AppendFormat(CssTemplate + Environment.NewLine, urlHelper.Content(file.VirtualFile.VirtualPath));
      }

      return new MvcHtmlString(sb.ToString());
    }

    public static MvcHtmlString Render(string bundleUrl, bool bundle)
    {
      return ResolveBundleUrl(bundleUrl, bundle);
    }
  }

}

Then in the razor layout file:

@OptionalCssBundler.Render("~/Content/css", false)

instead of the standard:

@Styles.Render("~/Content/css")

I am sure creating an optional renderer for javascript files would need little to update to this helper as well.

Quote from The Swift Programming Language, which answers your question:

“Swift’s compiler performs four helpful safety-checks to make sure that two-phase initialization is completed without error:”

Safety check 1 “A designated initializer must ensure that all of the “properties introduced by its class are initialized before it delegates up to a superclass initializer.”

I think buffers are e.g. useful when interfacing python to native libraries. (Guido van Rossum explains buffer in this mailinglist post).

For example, numpy seems to use buffer for efficient data storage:

import numpy
a = numpy.ndarray(1000000)

the a.data is a:

<read-write buffer for 0x1d7b410, size 8000000, offset 0 at 0x1e353b0>

Use bin folder and exe instead. Path will be C:\Program Files (x86)\Git\bin\git.exe

Also sometimes it doesn't work if there are blank spaces in path name as in your program files directory name.

In that case, copy the whole git folder to root of partition and then link studio to it

Regular expressions allow for everything that LIKE allows for, and much more, but have a completely different syntax. However, since the rules for LIKE are so simple(where % means zero-or-more characters and _ means one character), and both LIKE arguments and regular expressions are expressed in strings, we can create a regular expression that takes a LIKE argument (e.g. abc_ef% *usd) and turn it into the equivalent regular expression (e.g. \Aabc.ef.* \*usd\z):

@"\A" + new Regex(@"\.|\$|\^|\{|\[|\(|\||\)|\*|\+|\?|\\").Replace(toFind, ch => @"\" + ch).Replace('_', '.').Replace("%", ".*") + @"\z"

From that we can build a Like() method:

public static class MyStringExtensions
{
  public static bool Like(this string toSearch, string toFind)
  {
    return new Regex(@"\A" + new Regex(@"\.|\$|\^|\{|\[|\(|\||\)|\*|\+|\?|\\").Replace(toFind, ch => @"\" + ch).Replace('_', '.').Replace("%", ".*") + @"\z", RegexOptions.Singleline).IsMatch(toSearch);
  }
}

And hence:

bool willBeTrue = "abcdefg".Like("abcd_fg");
bool willAlsoBeTrue = "abcdefg".Like("ab%f%");
bool willBeFalse = "abcdefghi".Like("abcd_fg");

If a proper encryption method was used, it's not going to be possible to easily retrieve them.

Just reset them with new passwords.

Edit: The string looks like it is using PASSWORD():

UPDATE user SET password = PASSWORD("newpassword");

This happened to me once after I merged a pull request on Bitbucket.

I just had to do:

git fetch

My problem was solved. I hope this helps!!!

On MAC

Step 1: Alt + Cmd + F . At the bottom, a window appears Step 2: Enable Regular Expression. Left side on the window, looks like .* Step 3: Enter text to you want to find in the Find input field Step 4: Enter replace text in the Replace input field Step 5: Click on Replace All - Right bottom.

None of these worked for me. I had to do:

  this.myForm.get('myVal').setValue(val);

It was bothering me that implementing a listener for all of my EditText fields required me to have ugly, verbose code so I wrote the below class. May be useful to anyone stumbling upon this.

public abstract class TextChangedListener<T> implements TextWatcher {
    private T target;

    public TextChangedListener(T target) {
        this.target = target;
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {}

    @Override
    public void afterTextChanged(Editable s) {
        this.onTextChanged(target, s);
    }

    public abstract void onTextChanged(T target, Editable s);
}

Now implementing a listener is a little bit cleaner.

editText.addTextChangedListener(new TextChangedListener<EditText>(editText) {
            @Override
            public void onTextChanged(EditText target, Editable s) {
                //Do stuff
            }
        });

As for how often it fires, one could maybe implement a check to run their desired code in //Do stuff after a given a

Isn't string.replace returning a value, rather than modifying the source string?

So if you wanted to modify variableABC, you'd need to do this:

var variableABC = "A B C";

variableABC = variableABC.replace('B', 'D') //output: 'A D C'

Update: In modern browsers you can use the form attribute to do this.

As far as I know, you cannot do this without javascript.

Here's what the spec says

The elements used to create controls generally appear inside a FORM element, but may also appear outside of a FORM element declaration when they are used to build user interfaces. This is discussed in the section on intrinsic events. Note that controls outside a form cannot be successful controls.

That's my bold

A submit button is considered a control.

http://www.w3.org/TR/html4/interact/forms.html#h-17.2.1

From the comments

I have a multi tabbed settings area with a button to update all, due to the design of it the button would be outside of the form.

Why not place the input inside the form, but use CSS to position it elsewhere on the page?

You can't do it (yet) with string interpolation. Your best bet is still going to be NSString formatting:

println(NSString(format:"%.2f", sqrt(2.0)))

Extrapolating from python, it seems like a reasonable syntax might be:

@infix func % (value:Double, format:String) -> String {
    return NSString(format:format, value)
}

Which then allows you to use them as:

M_PI % "%5.3f"                // "3.142"

You can define similar operators for all of the numeric types, unfortunately I haven't found a way to do it with generics.

Swift 5 Update

As of at least Swift 5, String directly supports the format: initializer, so there's no need to use NSString and the @infix attribute is no longer needed which means the samples above should be written as:

println(String(format:"%.2f", sqrt(2.0)))

func %(value:Double, format:String) -> String {
    return String(format:format, value)
}

Double.pi % "%5.3f"         // "3.142"

I realize this is a very old question with an accepted answer, but none of these answers actually use the approach suggested by the hint.

It is a pretty simple argument:

n! (= 1*2*3*...*n) is a product of n numbers each less than or equal to n. Therefore it is less than the product of n numbers all equal to n; i.e., n^n.

Half of the numbers -- i.e. n/2 of them -- in the n! product are greater than or equal to n/2. Therefore their product is greater than the product of n/2 numbers all equal to n/2; i.e. (n/2)^(n/2).

Take logs throughout to establish the result.

The zoom property sounds as though it's perfect for Adam Ernst as it suits his target device. However, for those who need a solution to this and have to support as many devices as possible you can do the following:

<img src="..." onload="this.width/=2;this.onload=null;" />

The reason for the this.onload=null addition is to avoid older browsers that sometimes trigger the load event twice (which means you can end up with quater-sized images). If you aren't worried about that though you could write:

<img src="..." onload="this.width/=2;" />

Which is quite succinct.

One (dirty) way to do it is to use tryCatch with an empty function for error handling. For example, the following code raises an error and breaks the loop :

for (i in 1:10) {
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
Erreur : Urgh, the iphone is in the blender !

But you can wrap your instructions into a tryCatch with an error handling function that does nothing, for example :

for (i in 1:10) {
  tryCatch({
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")
  }, error=function(e){})
}

[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
[1] 8
[1] 9
[1] 10

But I think you should at least print the error message to know if something bad happened while letting your code continue to run :

for (i in 1:10) {
  tryCatch({
    print(i)
    if (i==7) stop("Urgh, the iphone is in the blender !")

EDIT : So to apply tryCatch in your case would be something like :

for (v in 2:180){
    tryCatch({
        mypath=file.path("C:", "file1", (paste("graph",names(mydata[columnname]), ".pdf", sep="-")))
        pdf(file=mypath)
        mytitle = paste("anything")
        myplotfunction(mydata[,columnnumber]) ## this function is defined previously in the program
        dev.off()
    }, error=function(e){cat("ERROR :",conditionMessage(e), "\n")})
}

Based on Cameron's initial answer, here is what I've just added at my enhanced version of SilverFlow library's FloatingWindowHost (copying from FloatingWindowHost.cs at http://clipflair.codeplex.com source code)

    public int MaxZIndex
    {
      get {
        return FloatingWindows.Aggregate(-1, (maxZIndex, window) => {
          int w = Canvas.GetZIndex(window);
          return (w > maxZIndex) ? w : maxZIndex;
        });
      }
    }

    private void SetTopmost(UIElement element)
    {
        if (element == null)
            throw new ArgumentNullException("element");

        Canvas.SetZIndex(element, MaxZIndex + 1);
    }

Worth noting regarding the code above that Canvas.ZIndex is an attached property available for UIElements in various containers, not just used when being hosted in a Canvas (see Controlling rendering order (ZOrder) in Silverlight without using the Canvas control). Guess one could even make a SetTopmost and SetBottomMost static extension method for UIElement easily by adapting this code.

$ grep -w

Excerpt from grep man page:

-w: Select only those lines containing matches that form whole words. The test is that the matching substring must either be at the beginning of the line, or preceded by a non-word constituent character.

Try this

AlphaAnimation animation1 = new AlphaAnimation(0.2f, 1.0f);
animation1.setDuration(1000);
animation1.setStartOffset(5000);
animation1.setFillAfter(true);
iv.startAnimation(animation1);

Out of curiosity, I found a box with a GNU version of sed (v4.1.5) and tested the (uncached) performance of two approaches suggested so far, using an 11M line text file:

$ wc -l input
11771722 input

$ time head -1000 input > output; time tail -n +1000 input > input.tmp; time cp input.tmp input; time rm input.tmp

real    0m1.165s

This is the Linux I was working with:

$ uname -a
Linux hostname 2.6.18-128.1.1.el5 #1 SMP Mon Jan 26 13:58:24 EST 2009 x86_64 x86_64 x86_64 GNU/Linux

For this test, at least, it looks like sed is slower than the tail approach (27 sec vs ~14 sec).

For hide:

$("#id").css("display", "none");

For show:

$("#id").css("display", "");

Well, I used to do this way:

Imagine, you have 500 commits, and your erroneous commit message is in r.498.

hg qimport -r 498:tip
hg qpop -a

(change the comment, after the mercurial header)
hg qpush -a
hg qdelete -r qbase:qtip

app.config

app.name=Properties Sample Code
app.version=1.09  

Source code:

Properties prop = new Properties();
String fileName = "app.config";
InputStream is = null;
try {
    is = new FileInputStream(fileName);
} catch (FileNotFoundException ex) {

try {
    prop.load(is);
} catch (IOException ex) {

}
System.out.println(prop.getProperty("app.name"));

Simple example: Form with textbox and Search button.

If you write "name" into the textbox and submit form, it will brings you patients with "name" in table.

View:

@using (Ajax.BeginForm("GetPatients", "Patient", new AjaxOptions {//GetPatients is name of method in PatientController
    InsertionMode = InsertionMode.Replace, //target element(#patientList) will be replaced
    UpdateTargetId = "patientList",
    LoadingElementId = "loader" // div with .gif loader - that is shown when data are loading   
}))
{
    string patient_Name = "";
    @Html.EditorFor(x=>patient_Name) //text box with name and id, that it will pass to controller
    <input  type="submit" value="Search" />
}

@* ... *@
<div id="loader" class=" aletr" style="display:none">
    Loading...<img src="~/Images/ajax-loader.gif" />
</div>
@Html.Partial("_patientList") @* this is view with patient table. Same view you will return from controller *@

_patientList.cshtml:

@model IEnumerable<YourApp.Models.Patient>

<table id="patientList" >
<tr>
    <th>
        @Html.DisplayNameFor(model => model.Name)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.Number)
    </th>       
</tr>
@foreach (var patient in Model) {
<tr>
    <td>
        @Html.DisplayFor(modelItem => patient.Name)
    </td>
    <td>
        @Html.DisplayFor(modelItem => patient.Number)
    </td>
</tr>
}
</table>

Patient.cs

public class Patient
{
   public string Name { get; set; }
   public int Number{ get; set; }
}

PatientController.cs

public PartialViewResult GetPatients(string patient_Name="")
{
   var patients = yourDBcontext.Patients.Where(x=>x.Name.Contains(patient_Name))
   return PartialView("_patientList", patients);
}

And also as TSmith said in comments, don´t forget to install jQuery Unobtrusive Ajax library through NuGet.

ssh-keygen isn't a windows executable.
You can use PuttyGen (http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html) for example to create a key

If you need to change the IDs occasionally, it's probably best not to use an identity column. In the past we've implemented autonumber fields manually using a 'Counters' table that tracks the next ID for each table. IIRC we did this because identity columns were causing database corruption in SQL2000 but being able to change IDs was occasionally useful for testing.

An alternative to whoami is id -u -n.

id -u will return the user id (e.g. 0 for root).

With Eclipse 3.7 Indigo, I found the link at http://www.eclipse.org/mpc/ which told me the download location and plugin was http://download.eclipse.org/mpc/indigo/ Which made the "Eclipse Marketplace Client" available in my Software updates after I added that address as a repository. Didn't seem to be in the core list on a fresh install.

None of the solutions above were working for me. My workaround was to open the on-screen keyboard using the system settings (press Windows key and search for "keyboard" to find them). Once that's open you can click the Insert key on it.

here is a solution if you are not using jquery:

myArray = myArray.filter(function( obj ) {
  return obj.id !== id;
});

When building big tables speed is a concern so Jamie Dixon's second function is best, but it doesn't completely work as is...

It fails to take all of the letters to lowercase, and it only capitalizes the first letter of the string, not the first letter of each word in the string... the below option fixes both issues:

    public string UppercaseFirstEach(string s)
    {
        char[] a = s.ToLower().ToCharArray();

        for (int i = 0; i < a.Count(); i++ )
        {
            a[i] = i == 0 || a[i-1] == ' ' ? char.ToUpper(a[i]) : a[i];

        }

        return new string(a);
    }

Although at this point, whether this is still the fastest option is uncertain, the Regex solution provided by George Mauer might be faster... someone who cares enough should test it.

When Python parses the body of a function definition and encounters an assignment such as

feed = ...

Python interprets feed as a local variable by default. If you do not wish for it to be a local variable, you must put

global feed

in the function definition. The global statement does not have to be at the beginning of the function definition, but that is where it is usually placed. Wherever it is placed, the global declaration makes feed a global variable everywhere in the function.

Without the global statement, since feed is taken to be a local variable, when Python executes

feed = feed + 1,

Python evaluates the right-hand side first and tries to look up the value of feed. The first time through it finds feed is undefined. Hence the error.

The shortest way to patch up the code is to add global feed to the beginning of onLoadFinished. The nicer way is to use a class:

class Page(object):
    def __init__(self):
        self.feed = 0
    def onLoadFinished(self, result):
        ...
        self.feed += 1

The problem with having functions which mutate global variables is that it makes it harder to grok your code. Functions are no longer isolated units. Their interaction extends to everything that affects or is affected by the global variable. Thus it makes larger programs harder to understand.

By avoiding mutating globals, in the long run your code will be easier to understand, test and maintain.

ok. I tried the above two ways but it didnt work for me. After trial and error i came to know that actually the file was not getting saved in 'this.state.file' variable.

fileUpload = (e) => {
    let data = e.target.files
    if(e.target.files[0]!=null){
        this.props.UserAction.fileUpload(data[0], this.fallBackMethod)
    }
}

here fileUpload is a different js file which accepts two params like this

export default (file , callback) => {
const formData = new FormData();
formData.append('fileUpload', file);

return dispatch => {
    axios.put(BaseUrl.RestUrl + "ur/url", formData)
        .then(response => {
            callback(response.data);
        }).catch(error => {
         console.log("*****  "+error)
    });
}

}

don't forget to bind method in the constructor. Let me know if you need more help in this.

This could also be due to having custom named schemes, in that case:

• cd ios
• xcodebuild -list

Find your's, it might have a -dev suffix. Then:

• cd .. (root of the app)
• npx react-native run-ios --scheme custom-scheme-name

Just use GETDATE() or GETUTCDATE() (if you want to get the "universal" UTC time, instead of your local server's time-zone related time).

INSERT INTO [Business]
           ([IsDeleted]
           ,[FirstName]
           ,[LastName]
           ,[LastUpdated]
           ,[LastUpdatedBy])
     VALUES
           (0, 'Joe', 'Thomas', 
           GETDATE(),  <LastUpdatedBy, nvarchar(50),>)

You can write:

"line 1" +
"line 2" +
"line 3"

which is the same as:

"line 1line 2line 3"

Unlike using back ticks, it will preserve escape characters. Note that the "+" must be on the 'leading' line - for instance, the following will generate an error:

"line 1"
+"line 2"

I go into more detail here, but still keeping things simple: https://jorgecolonconsulting.com/saml-sso-in-simple-terms/.

doAnswer and thenReturn do the same thing if:

1. You are using Mock, not Spy
2. The method you're stubbing is returning a value, not a void method.

Let's mock this BookService

public interface BookService {
    String getAuthor();
    void queryBookTitle(BookServiceCallback callback);
}

You can stub getAuthor() using doAnswer and thenReturn.

BookService service = mock(BookService.class);
when(service.getAuthor()).thenReturn("Joshua");
// or..
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        return "Joshua";
    }
}).when(service).getAuthor();

Note that when using doAnswer, you can't pass a method on when.

// Will throw UnfinishedStubbingException
doAnswer(invocation -> "Joshua").when(service.getAuthor());

So, when would you use doAnswer instead of thenReturn? I can think of two use cases:

1. When you want to "stub" void method.

Using doAnswer you can do some additionals actions upon method invocation. For example, trigger a callback on queryBookTitle.

BookServiceCallback callback = new BookServiceCallback() {
    @Override
    public void onSuccess(String bookTitle) {
        assertEquals("Effective Java", bookTitle);
    }
};
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        BookServiceCallback callback = (BookServiceCallback) invocation.getArguments()[0];
        callback.onSuccess("Effective Java");
        // return null because queryBookTitle is void
        return null;
    }
}).when(service).queryBookTitle(callback);
service.queryBookTitle(callback);

2. When you are using Spy instead of Mock

When using when-thenReturn on Spy Mockito will call real method and then stub your answer. This can cause a problem if you don't want to call real method, like in this sample:

List list = new LinkedList();
List spy = spy(list);
// Will throw java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
when(spy.get(0)).thenReturn("java");
assertEquals("java", spy.get(0));

Using doAnswer we can stub it safely.

List list = new LinkedList();
List spy = spy(list);
doAnswer(invocation -> "java").when(spy).get(0);
assertEquals("java", spy.get(0));

Actually, if you don't want to do additional actions upon method invocation, you can just use doReturn.

List list = new LinkedList();
List spy = spy(list);
doReturn("java").when(spy).get(0);
assertEquals("java", spy.get(0));

The example implementation when you want to have an abstract class with implementation. Subclasses must:

1. Parameterize the implementation of an abstract class.
2. Fully inherit the implementation of the abstract class;
3. Have your own implementation.

In this case, the properties that are necessary for the implementation should not be available for use except for the abstract class and its own subclass.

    internal abstract class AbstractClass
    {
        //Properties for parameterization from concrete class
        protected abstract string Param1 { get; }
        protected abstract string Param2 { get; }

        //Internal fields need for manage state of object
        private string var1;
        private string var2;

        internal AbstractClass(string _var1, string _var2)
        {
            this.var1 = _var1;
            this.var2 = _var2;
        }

        internal void CalcResult()
        {
            //The result calculation uses Param1, Param2, var1, var2;
        }
    }

    internal class ConcreteClassFirst : AbstractClass
    {
        private string param1;
        private string param2;
        protected override string Param1 { get { return param1; } }
        protected override string Param2 { get { return param2; } }

        public ConcreteClassFirst(string _var1, string _var2) : base(_var1, _var2) { }

        internal void CalcParams()
        {
            //The calculation param1 and param2
        }
    }

    internal class ConcreteClassSecond : AbstractClass
    {
        private string param1;
        private string param2;

        protected override string Param1 { get { return param1; } }

        protected override string Param2 { get { return param2; } }

        public ConcreteClassSecond(string _var1, string _var2) : base(_var1, _var2) { }

        internal void CalcParams()
        {
            //The calculation param1 and param2
        }
    }

    static void Main(string[] args)
    {
        string var1_1 = "val1_1";
        string var1_2 = "val1_2";

        ConcreteClassFirst concreteClassFirst = new ConcreteClassFirst(var1_1, var1_2);
        concreteClassFirst.CalcParams();
        concreteClassFirst.CalcResult();

        string var2_1 = "val2_1";
        string var2_2 = "val2_2";

        ConcreteClassSecond concreteClassSecond = new ConcreteClassSecond(var2_1, var2_2);
        concreteClassSecond.CalcParams();
        concreteClassSecond.CalcResult();

        //Param1 and Param2 are not visible in main method
    }

select case when IsNull(CONVERT(DATE, StartDate),'')='' then 'NA' else Convert(varchar(10),StartDate,121) end from table1

First of all, there are still browsers out there that don't support those pseudo-elements (ie. :first-child, :last-child), so you have to 'deal' with this issue.

There is a good example how to make that work without using pseudo-elements:

http://www.darowski.com/tracesofinspiration/2010/01/11/this-newbies-first-impressions-of-haml-and-sass/

       -- see the divider pipe example.

I hope that was useful.

This topic is quite old, but here is a handy solution that I found:

http://www.cityinthesky.co.uk/opensource/pdf2svg/

It offers a tool, pdf2png, which once installed does exactly the job in command line. I've tested it with irreproachable results so far, including with bitmaps.

EDIT : My mistake, this tool also converts letters to paths, so it does not address the initial question. However it does a good job anyway, and can be useful to anyone who does not intend to modify the code in the svg file, so I'll leave the post.

This worked for me (Ubuntu):

Add ANDROID_HOME=/path/to/android-sdk to /etc/environment.

Reboot.

Use the Columns Property and set the Auto Size Mode to All Cells, Resizable to True, Frozen to False and visible to True.

The column will automatically resize based on the data inserted.

Since PostgreSQL 10

CREATE TABLE test_new (
    id int GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
    payload text
);

API 21 has view.setElevation(float) build-in

Use ViewCompat.setElevation(view, float); for backward compatibility

More methods ViewCompat.setZ(v, pixels) and ViewCompat.setTranslationZ(v, pixels)

Another way collect buttons or view array and use addView to add to RelativeLayout

Why do we need Unicode?

In the (not too) early days, all that existed was ASCII. This was okay, as all that would ever be needed were a few control characters, punctuation, numbers and letters like the ones in this sentence. Unfortunately, today's strange world of global intercommunication and social media was not foreseen, and it is not too unusual to see English, ???????, ??, ????????, e???????, and ????????? in the same document (I hope I didn't break any old browsers).

But for argument's sake, lets say Joe Average is a software developer. He insists that he will only ever need English, and as such only wants to use ASCII. This might be fine for Joe the user, but this is not fine for Joe the software developer. Approximately half the world uses non-Latin characters and using ASCII is arguably inconsiderate to these people, and on top of that, he is closing off his software to a large and growing economy.

Therefore, an encompassing character set including all languages is needed. Thus came Unicode. It assigns every character a unique number called a code point. One advantage of Unicode over other possible sets is that the first 256 code points are identical to ISO-8859-1, and hence also ASCII. In addition, the vast majority of commonly used characters are representable by only two bytes, in a region called the Basic Multilingual Plane (BMP). Now a character encoding is needed to access this character set, and as the question asks, I will concentrate on UTF-8 and UTF-16.

Memory considerations

So how many bytes give access to what characters in these encodings?

• UTF-8:
  • 1 byte: Standard ASCII
  • 2 bytes: Arabic, Hebrew, most European scripts (most notably excluding Georgian)
  • 3 bytes: BMP
  • 4 bytes: All Unicode characters
• UTF-16:
  • 2 bytes: BMP
  • 4 bytes: All Unicode characters

It's worth mentioning now that characters not in the BMP include ancient scripts, mathematical symbols, musical symbols, and rarer Chinese/Japanese/Korean (CJK) characters.

If you'll be working mostly with ASCII characters, then UTF-8 is certainly more memory efficient. However, if you're working mostly with non-European scripts, using UTF-8 could be up to 1.5 times less memory efficient than UTF-16. When dealing with large amounts of text, such as large web-pages or lengthy word documents, this could impact performance.

Encoding basics

^{Note: If you know how UTF-8 and UTF-16 are encoded, skip to the next section for practical applications.}

• UTF-8: For the standard ASCII (0-127) characters, the UTF-8 codes are identical. This makes UTF-8 ideal if backwards compatibility is required with existing ASCII text. Other characters require anywhere from 2-4 bytes. This is done by reserving some bits in each of these bytes to indicate that it is part of a multi-byte character. In particular, the first bit of each byte is 1 to avoid clashing with the ASCII characters.
• UTF-16: For valid BMP characters, the UTF-16 representation is simply its code point. However, for non-BMP characters UTF-16 introduces surrogate pairs. In this case a combination of two two-byte portions map to a non-BMP character. These two-byte portions come from the BMP numeric range, but are guaranteed by the Unicode standard to be invalid as BMP characters. In addition, since UTF-16 has two bytes as its basic unit, it is affected by endianness. To compensate, a reserved byte order mark can be placed at the beginning of a data stream which indicates endianness. Thus, if you are reading UTF-16 input, and no endianness is specified, you must check for this.

As can be seen, UTF-8 and UTF-16 are nowhere near compatible with each other. So if you're doing I/O, make sure you know which encoding you are using! For further details on these encodings, please see the UTF FAQ.

Practical programming considerations

Character and String data types: How are they encoded in the programming language? If they are raw bytes, the minute you try to output non-ASCII characters, you may run into a few problems. Also, even if the character type is based on a UTF, that doesn't mean the strings are proper UTF. They may allow byte sequences that are illegal. Generally, you'll have to use a library that supports UTF, such as ICU for C, C++ and Java. In any case, if you want to input/output something other than the default encoding, you will have to convert it first.

Recommended/default/dominant encodings: When given a choice of which UTF to use, it is usually best to follow recommended standards for the environment you are working in. For example, UTF-8 is dominant on the web, and since HTML5, it has been the recommended encoding. Conversely, both .NET and Java environments are founded on a UTF-16 character type. Confusingly (and incorrectly), references are often made to the "Unicode encoding", which usually refers to the dominant UTF encoding in a given environment.

Library support: The libraries you are using support some kind of encoding. Which one? Do they support the corner cases? Since necessity is the mother of invention, UTF-8 libraries will generally support 4-byte characters properly, since 1, 2, and even 3 byte characters can occur frequently. However, not all purported UTF-16 libraries support surrogate pairs properly since they occur very rarely.

Counting characters: There exist combining characters in Unicode. For example the code point U+006E (n), and U+0303 (a combining tilde) forms ñ, but the code point U+00F1 forms ñ. They should look identical, but a simple counting algorithm will return 2 for the first example, 1 for the latter. This isn't necessarily wrong, but may not be the desired outcome either.

Comparing for equality: A, А, and Α look the same, but they're Latin, Cyrillic, and Greek respectively. You also have cases like C and Ⅽ, one is a letter, the other a Roman numeral. In addition, we have the combining characters to consider as well. For more info see Duplicate characters in Unicode.

Surrogate pairs: These come up often enough on SO, so I'll just provide some example links:

• Getting string length
• Removing surrogate pairs
• Palindrome checking

Others?:

This is the solution which can avoid using function:

alias addone='{ num=$(cat -); echo "input: $num"; echo "result:$(($num+1))"; }<<<'

test result

addone 200
input: 200

There is not. You will need to use some external library, or write your own parser. If you have the time to do so, I suggest to write your own parser as it is a quite interesting project. Otherwise you will need to use something like bcParser.

You can maintain your html as it is but use this php code

<?php
    $name = $_POST['name'];
    $purchase1 = $_POST['Tea'];
    $purchase2 =$_POST['Coffee'];
?>

As you can see, the import command did work but is showing errors because it tried to locate the resources in vendor.css and couldn't find them

You should also upload your project structure and ensure that there aren't any path issues. Also, you could include the css file in the index.html or the Component template and webpack loader would extract it when built

WAMP Server – MySQL – Resetting the Root Password (Windows)

1. Log on to your system as Administrator.

2. Click on the Wamp server icon > MySQL > MySQL Console

3. Enter password: LEAVE BLANK AND HIT ENTER

4. mysql> UPDATE mysql.user SET Password=PASSWORD(‘MyNewPass’) WHERE User=’root’; ENTER Query OK

5. mysql>FLUSH PRIVILEGES; ENTER mysql>quit ENTER mysql>bye

6. Edit phpmyadmin file called “config.inc.php” enter ‘MyNewPass’ ($cfg['Servers'][$i]['password'] = ‘MyNewPass‘;)

7. Restart all services

8. Clear all cookies – I got the No password error and it was because of the cookies. (ERROR 1045: Access denied for user: ‘root@localhost’ (Using password: NO))

If you are looking for ad-hoc items rather than something that you would put into SSIS. From within SSMS simply highlight the results grid, copy, then paste into excel, it isn't elegant, but works. Then you can save as native .xls rather than .csv

Click on the error message displaying "Unbound classpath container: 'JRE System Library[jdk1.5.0_08]", left click anyd choose quick fix. Under quick, list of possible options will get displated. Choose replace library. Choose the library you installed. Your good to go.

This code removes the inner html of an element from the dom when the debugger is open (tested in Chrome and IE)

var currentInnerHtml;
var element = new Image();
var elementWithHiddenContent = document.querySelector("#element-to-hide");
var innerHtml = elementWithHiddenContent.innerHTML;

element.__defineGetter__("id", function() {
    currentInnerHtml = "";
});

setInterval(function() {
    currentInnerHtml = innerHtml;
    console.log(element);
    console.clear();
    elementWithHiddenContent.innerHTML = currentInnerHtml;
}, 1000);

Here #element-to-hide is the id of element you want to hide. It is a hack, but I hope it helps you.

One pragmatic tip: you can search easily for the static_cast keyword in your source code if you plan to tidy up the project.

Using touchstart or touchend alone is not a good solution, because if you scroll the page, the device detects it as touch or tap too. So, the best way to detect a tap and click event at the same time is to just detect the touch events which are not moving the screen (scrolling). So to do this, just add this code to your application:

$(document).on('touchstart', function() {
    detectTap = true; // Detects all touch events
});
$(document).on('touchmove', function() {
    detectTap = false; // Excludes the scroll events from touch events
});
$(document).on('click touchend', function(event) {
    if (event.type == "click") detectTap = true; // Detects click events
       if (detectTap){
          // Here you can write the function or codes you want to execute on tap

       }
 });

I tested it and it works fine for me on iPad and iPhone. It detects tap and can distinguish tap and touch scroll easily.

The two query mechanism work in different ways, as suggested in the docs at the section Subdocuments:

When the field holds an embedded document (i.e, subdocument), you can either specify the entire subdocument as the value of a field, or “reach into” the subdocument using dot notation, to specify values for individual fields in the subdocument:

Equality matches within subdocuments select documents if the subdocument matches exactly the specified subdocument, including the field order.

In the following example, the query matches all documents where the value of the field producer is a subdocument that contains only the field company with the value 'ABC123' and the field address with the value '123 Street', in the exact order:

db.inventory.find( {
    producer: {
        company: 'ABC123',
        address: '123 Street'
    }
});

The problem is with the API interaction method. The JSON parsing is changed only in syntax. The main problem is with the way of fetching data. What you are using is a synchronous way of getting data. This doesn't work in every case. What you should be using is an asynchronous way to fetch data. In this way, you have to request data through the API and wait for it to respond with data. You can achieve this with URL session and third party libraries like Alamofire. Below is the code for URL Session method.

let urlString = "https://api.forecast.io/forecast/apiKey/37.5673776,122.048951"
let url = URL.init(string: urlString)
URLSession.shared.dataTask(with:url!) { (data, response, error) in
    guard error == nil else {
        print(error)
    }
    do {
        let Data = try JSONSerialization.jsonObject(with: data!) as! [String:Any]
        // Note if your data is coming in Array you should be using [Any]()
        //Now your data is parsed in Data variable and you can use it normally
        let currentConditions = Data["currently"] as! [String:Any]
        print(currentConditions)
        let currentTemperatureF = currentConditions["temperature"] as! Double
        print(currentTemperatureF)
    } catch let error as NSError {
        print(error)
    }
}.resume()

alter table table_name add field_name (size);

The accepted answer is great for single renames, but here is a way to rename multiple images that have the same repository all at once (and remove the old images).

If you have old images of the form:

$ docker images
REPOSITORY               TAG                 IMAGE ID            CREATED             SIZE
old_name/image_name_1    latest              abcdefghijk1        5 minutes ago      1.00GB
old_name/image_name_2    latest              abcdefghijk2        5 minutes ago      1.00GB

And you want:

new_name/image_name_1
new_name/image_name_2

Then you can use this (subbing in OLD_REPONAME, NEW_REPONAME, and TAG as appropriate):

OLD_REPONAME='old_name'
NEW_REPONAME='new_name'
TAG='latest'

# extract image name, e.g. "old_name/image_name_1"
for image in $(docker images | awk '{ if( FNR>1 ) { print $1 } }' | grep $OLD_REPONAME)
do \
  OLD_NAME="${image}:${TAG}" && \
  NEW_NAME="${NEW_REPONAME}${image:${#OLD_REPONAME}:${#image}}:${TAG}" && \
  docker image tag $OLD_NAME $NEW_NAME && \
  docker rmi $image:${TAG}  # omit this line if you want to keep the old image
done

You can set the year range using this option in jQuery UI datepicker:

yearRange: "c-100:c+0", // last hundred years and current years

yearRange: "c-100:c+100", // last hundred years and future hundred years

yearRange: "c-10:c+10", // last ten years and future ten years

Simply do:

grouped_df = df.groupby('A')

for key, item in grouped_df:
    print(grouped_df.get_group(key), "\n\n")

This also works,

grouped_df = df.groupby('A')    
gb = grouped_df.groups

for key, values in gb.iteritems():
    print(df.ix[values], "\n\n")

For selective key grouping: Insert the keys you want inside the key_list_from_gb, in following, using gb.keys(): For Example,

gb = grouped_df.groups
gb.keys()

key_list_from_gb = [key1, key2, key3]

for key, values in gb.items():
    if key in key_list_from_gb:
        print(df.ix[values], "\n")

At line 5 there is a / missing.

There is a good answer on the differences between ; and / here.

Basically, when running a CREATE block via script, you need to use / to let SQLPlus know when the block ends, since a PL/SQL block can contain many instances of ;.

The difference between absolute and relative imports come into play only when you import a module from a package and that module imports an other submodule from that package. See the difference:

$ mkdir pkg
$ touch pkg/__init__.py
$ touch pkg/string.py
$ echo 'import string;print(string.ascii_uppercase)' > pkg/main1.py
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "pkg/main1.py", line 1, in <module>
    import string;print(string.ascii_uppercase)
AttributeError: 'module' object has no attribute 'ascii_uppercase'
>>> 
$ echo 'from __future__ import absolute_import;import string;print(string.ascii_uppercase)' > pkg/main2.py
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ
>>> 

In particular:

$ python2 pkg/main2.py
Traceback (most recent call last):
  File "pkg/main2.py", line 1, in <module>
    from __future__ import absolute_import;import string;print(string.ascii_uppercase)
AttributeError: 'module' object has no attribute 'ascii_uppercase'
$ python2
Python 2.7.9 (default, Dec 13 2014, 18:02:08) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ
>>> 
$ python2 -m pkg.main2
ABCDEFGHIJKLMNOPQRSTUVWXYZ

Note that python2 pkg/main2.py has a different behaviour then launching python2 and then importing pkg.main2 (which is equivalent to using the -m switch).

If you ever want to run a submodule of a package always use the -m switch which prevents the interpreter for chaining the sys.path list and correctly handles the semantics of the submodule.

Also, I much prefer using explicit relative imports for package submodules since they provide more semantics and better error messages in case of failure.

What I do in my scripts is check at runtime if the 'verbose' option is set, and then set my logging level to debug. If it's not set, I set it to info. This way you don't have 'if verbose' checks all over your code.

Sorry, I wasn't sure which SQL platform you're talking about:

In MySQL:

$query = ("SELECT * FROM $db WHERE conditions AND LENGTH(col_name) = 3");

in MSSQL

$query = ("SELECT * FROM $db WHERE conditions AND LEN(col_name) = 3");

The LENGTH() (MySQL) or LEN() (MSSQL) function will return the length of a string in a column that you can use as a condition in your WHERE clause.

Edit

I know this is really old but thought I'd expand my answer because, as Paulo Bueno rightly pointed out, you're most likely wanting the number of characters as opposed to the number of bytes. Thanks Paulo.

So, for MySQL there's the CHAR_LENGTH(). The following example highlights the difference between LENGTH() an CHAR_LENGTH():

CREATE TABLE words (
    word VARCHAR(100)
) ENGINE INNODB DEFAULT CHARSET utf8mb4 COLLATE utf8mb4_unicode_ci;

INSERT INTO words(word) VALUES('??'), ('happy'), ('hayir');

SELECT word, LENGTH(word) as num_bytes, CHAR_LENGTH(word) AS num_characters FROM words;

+--------+-----------+----------------+
| word   | num_bytes | num_characters |
+--------+-----------+----------------+
| ??    |         6 |              2 |
| happy  |         5 |              5 |
| hayir  |         6 |              5 |
+--------+-----------+----------------+

Be careful if you're dealing with multi-byte characters.

You can have fileZilla and use FTP Account to update plugins and themes. Or you can just login to Cpanel and access wordpress folder and then you can update theme by unzipping theme or plugin.

Indexing a list is done using double bracket, i.e. hypo_list[[1]] (e.g. have a look here: http://www.r-tutor.com/r-introduction/list). BTW: read.table does not return a table but a dataframe (see value section in ?read.table). So you will have a list of dataframes, rather than a list of table objects. The principal mechanism is identical for tables and dataframes though.

Note: In R, the index for the first entry is a 1 (not 0 like in some other languages).

Dataframes

l <- list(anscombe, iris)   # put dfs in list
l[[1]]             # returns anscombe dataframe

anscombe[1:2, 2]   # access first two rows and second column of dataset
[1] 10  8

l[[1]][1:2, 2]     # the same but selecting the dataframe from the list first
[1] 10  8

Table objects

tbl1 <- table(sample(1:5, 50, rep=T))
tbl2 <- table(sample(1:5, 50, rep=T))
l <- list(tbl1, tbl2)  # put tables in a list

tbl1[1:2]              # access first two elements of table 1 

Now with the list

l[[1]]                 # access first table from the list

1  2  3  4  5 
9 11 12  9  9 

l[[1]][1:2]            # access first two elements in first table

1  2 
9 11 

Use DateFormat#parse(String):

Date date = dateFormat.parse("2013-10-22");

This code should do the trick:

var array = ["ab", "abcdefgh", "abcd"];

array.sort(function(a, b){return b.length - a.length});

console.log(JSON.stringify(array, null, '\t'));

You may define your enum like so and use cast where needed

public enum MyEnum
{
    VariablePeriods = 1,
    FixedPeriods = 2
}

Usage

public class Entity
{
    public MyEnum Property { get; set; }
}

var returnedFromDB = 1;
var entity = new Entity();
entity.Property = (MyEnum)returnedFromDB;

To avoid memory leaks you may use smart pointers whenever you can. There are basically 2 different types of smart pointers in C++

• Reference counted (e.g. boost::shared_ptr / std::tr1:shared_ptr)
• non reference counted (e.g. boost::scoped_ptr / std::auto_ptr)

The main difference is that reference counted smart pointers can be copied (and used in std:: containers) while scoped_ptr cannot. Non reference counted pointers have almost no overhead or no overhead at all. Reference counting always introduces some kind of overhead.

(I suggest to avoid auto_ptr, it has some serious flaws if used incorrectly)

I can see that you want to write you own short javascript for this, but have you considered to use Frameworks for HTML manipulation instead? jQuery is my prefered tool for such a task, eventhough its an overkill for your current question as it has SO many extra functionalities.

Have a look at jQuery here

In order for this to work that Javascript must be placed within a Razor view so that the line

@Url.Action("Action","Controller")

is parsed by Razor and the real value replaced.

If you don't want to move your Javascript into your View you could look at creating a settings object in the view and then referencing that from your Javascript file.

e.g.

var MyAppUrlSettings = {
    MyUsefulUrl : '@Url.Action("Action","Controller")'
}

and in your .js file

$.ajax({
 type: "POST",
 url: MyAppUrlSettings.MyUsefulUrl,
 data: "{queryString:'" + searchVal + "'}",
 contentType: "application/json; charset=utf-8",
 dataType: "html",
 success: function (data) {
 alert("here" + data.d.toString());
});

or alternatively look at levering the framework's built in Ajax methods within the HtmlHelpers which allow you to achieve the same without "polluting" your Views with JS code.

I got same error and found that my Microsoft Visual C++ is 32 bit and Windows is 64 bit. I tried to install WAMP 7 32 bit and the problem was solved.

Maybe we need to install WAMP 32 bit if Visual Studio is 32 bit. And vice versa.

I noticed that when it's set to false, I'm able to see the value of an item using the debugger. When it was set to true, I was getting an error - item.FullName.GetValue The embedded interop type 'FullName' does not contain a definition for 'QBFC11Lib.IItemInventoryRet' since it was not used in the compiled assembly. Consider casting to object or changing the 'Embed Interop Types' property to true.

You can press ok and it will continue the insallation.

Otherwise, see Trying to reinstall XAMPP on windows 7, getting error messag...

The error message says that getComputedStyle requires the parameter to be Element type. You receive it because the parameter has an incorrect type.

The most common case is that you try to pass an element that doesn't exist as an argument:

my_element = document.querySelector(#non_existing_id);

Now that element is null, this will result in mentioned error:

my_style = window.getComputedStyle(my_element);

If it's not possible to always get element correctly, you can, for example, use the following to end function if querySelector didn't find any match:

if (my_element === null) return;

Just for future needs.

In Visual Studio 2013 with .NET Framework 4.5, for a window property, try adding ElementName=window to make it work.

<Grid Name="myGrid" Height="437.274">
  <TextBox Text="{Binding Path=Name2, ElementName=window}"/>
</Grid>

You need to use convert in order by as well:

SELECT  Convert(varchar,A.InsertDate,103) as Tran_Date
order by Convert(varchar,A.InsertDate,103)

I would caution that GUIDs are not random numbers. They should not be used as the basis to generate anything that you expect to be totally random (see http://en.wikipedia.org/wiki/Globally_Unique_Identifier):

Cryptanalysis of the WinAPI GUID generator shows that, since the sequence of V4 GUIDs is pseudo-random, given the initial state one can predict up to next 250 000 GUIDs returned by the function UuidCreate. This is why GUIDs should not be used in cryptography, e. g., as random keys.

Instead, just use the C# Random method. Something like this (code found here):

private string RandomString(int size)
{
  StringBuilder builder = new StringBuilder();
  Random random = new Random();
  char ch ;
  for(int i=0; i<size; i++)
  {
    ch = Convert.ToChar(Convert.ToInt32(Math.Floor(26 * random.NextDouble() + 65))) ;
    builder.Append(ch);
  }
  return builder.ToString();
}

GUIDs are fine if you want something unique (like a unique filename or key in a database), but they are not good for something you want to be random (like a password or encryption key). So it depends on your application.

Edit. Microsoft says that Random is not that great either (http://msdn.microsoft.com/en-us/library/system.random(VS.71).aspx):

To generate a cryptographically secure random number suitable for creating a random password, for example, use a class derived from System.Security.Cryptography.RandomNumberGenerator such as System.Security.Cryptography.RNGCryptoServiceProvider.

Here is what I use:

public static boolean onTablet()
    {
    int intScreenSize = getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK;

    return (intScreenSize == Configuration.SCREENLAYOUT_SIZE_LARGE) // LARGE
    || (intScreenSize == Configuration.SCREENLAYOUT_SIZE_LARGE + 1); // Configuration.SCREENLAYOUT_SIZE_XLARGE
    }

this worked fine for me:

class ItemSerializer(serializers.ModelSerializer):
    category_name = serializers.ReadOnlyField(source='category.name')
    class Meta:
        model = Item
        fields = "__all__"

Here is a function to print a PDF from an iframe.

You just need to pass the URL of the PDF to the function. It will create an iframe and trigger print once the PDF is load.

Note that the function doesn't destroy the iframe. Instead, it reuses it each time the function is call. It's hard to destroy the iframe because it is needed until the printing is done, and the print method doesn't has callback support (as far as I know).

printPdf = function (url) {
  var iframe = this._printIframe;
  if (!this._printIframe) {
    iframe = this._printIframe = document.createElement('iframe');
    document.body.appendChild(iframe);

    iframe.style.display = 'none';
    iframe.onload = function() {
      setTimeout(function() {
        iframe.focus();
        iframe.contentWindow.print();
      }, 1);
    };
  }

  iframe.src = url;
}

Meld (http://meldmerge.org/) does a great job at comparing directories and the files within.

This single line of code solved the problem for me:

event.currentTarget.getAttribute('data-tag')

myWebView.setAlpha(0);

is the best answer. It works!

Current best practice in CSS development is to create more general selectors with modifiers that can be applied as widely as possible throughout the web site. I would try to avoid defining separate styles for individual page elements.

If the purpose of the CSS class on the <form/> element is to control the style of elements within the form, you could add the class attribute the existing <fieldset/> element which encapsulates any form by default in web pages generated by ASP.NET MVC. A CSS class on the form is rarely necessary.

I suppose you're getting this JSON from a server or a file, and you want to create a JSONArray object out of it.

String strJSON = ""; // your string goes here
JSONArray jArray = (JSONArray) new JSONTokener(strJSON).nextValue();
// once you get the array, you may check items like
JSONOBject jObject = jArray.getJSONObject(0);

Hope this helps :)

The answer above has an incorrect assumption that the order of inclusion of the files matter. As the alertNumber function is not called until the alertOne function is called. As long as both files are included by time alertOne is called the order of the files does not matter:

[HTML]

<script type="text/javascript" src="file1.js"></script>
<script type="text/javascript" src="file2.js"></script>
<script type="text/javascript">
    alertOne( );
</script>

[JS]

// File1.js
function alertNumber( n ) {
    alert( n );
};
// File2.js
function alertOne( ) {
    alertNumber( "one" );
};
// Inline
alertOne( ); // No errors

Or it can be ordered like the following:

[HTML]

<script type="text/javascript" src="file2.js"></script>
<script type="text/javascript" src="file1.js"></script>
<script type="text/javascript">
    alertOne( );
</script>

[JS]

// File2.js
function alertOne( ) {
    alertNumber( "one" );
};
// File1.js
function alertNumber( n ) {
    alert( n );
};
// Inline
alertOne( ); // No errors

But if you were to do this:

[HTML]

<script type="text/javascript" src="file2.js"></script>
<script type="text/javascript">
    alertOne( );
</script>
<script type="text/javascript" src="file1.js"></script>

[JS]

// File2.js
function alertOne( ) {
    alertNumber( "one" );
};
// Inline
alertOne( ); // Error: alertNumber is not defined
// File1.js
function alertNumber( n ) {
    alert( n );
};

It only matters about the variables and functions being available at the time of execution. When a function is defined it does not execute or resolve any of the variables declared within until that function is then subsequently called.

Inclusion of different script files is no different from the script being in that order within the same file, with the exception of deferred scripts:

<script type="text/javascript" src="myscript.js" defer="defer"></script>

then you need to be careful.

<html>
<head>
    <style>
        #main { border: 1px #000 solid; width: 600px; height: 400px; margin: auto;}
        #one { width: 20%; height: 100%; background-color: blue; display: inline-block; }
        #two { width: 80%; height: 100%; background-color: red; display: inline-block; }
    </style>
</head>
<body>
<div id="main">
    <span id="one">one</span><span id="two">two</span>
</div>
</body>
</html>

The secret is the inline-block. If you use borders or margins, you may need to reduce the width of the div that use them.

NOTE: This doesn't work properly in IE6/7 if you use "DIV" instead of "SPAN". (see http://www.quirksmode.org/css/display.html)

When you say adding antMatchers doesnt help - what do you mean? antMatchers is exactly how you do it. Something like the following should work (obviously changing your URL appropriately):

@Override
    public void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/authFailure").permitAll()
                .antMatchers("/resources/**").permitAll()
                .anyRequest().authenticated()

If you are still not having any joy, then you will need to provide more details/stacktrace etc.

Details of XML to Java config switch is here

Something like this should work

$code = "screen new file.css";
if (!preg_match("/^[-_a-zA-Z0-9.]+$/", $code))
{
    echo "not valid";
}

This will echo "not valid"

On VS2017 I installed the NuGet package: Microsoft.AspNet.WebPages

That did the trick.

I have changed the order of included projects (Eclipse / Configure Build Path / Order and Export). I have moved my two dependent projects to the top of the "Order and Export" list. It solved the problem "NoClassDefFoundError".

It is strange for me. I didn't heard about the importance of the order of included libraries and projects. Android + Eclipse is fun :)

Maybe the following extract from the Chapter 23 - Using the Criteria API to Create Queries of the Java EE 6 tutorial will throw some light (actually, I suggest reading the whole Chapter 23):

Querying Relationships Using Joins

For queries that navigate to related entity classes, the query must define a join to the related entity by calling one of the From.join methods on the query root object, or another join object. The join methods are similar to the JOIN keyword in JPQL.

The target of the join uses the Metamodel class of type EntityType<T> to specify the persistent field or property of the joined entity.

The join methods return an object of type Join<X, Y>, where X is the source entity and Y is the target of the join.

Example 23-10 Joining a Query

CriteriaQuery<Pet> cq = cb.createQuery(Pet.class);
Metamodel m = em.getMetamodel();
EntityType<Pet> Pet_ = m.entity(Pet.class);

Root<Pet> pet = cq.from(Pet.class);
Join<Pet, Owner> owner = pet.join(Pet_.owners);

Joins can be chained together to navigate to related entities of the target entity without having to create a Join<X, Y> instance for each join.

Example 23-11 Chaining Joins Together in a Query

CriteriaQuery<Pet> cq = cb.createQuery(Pet.class);
Metamodel m = em.getMetamodel();
EntityType<Pet> Pet_ = m.entity(Pet.class);
EntityType<Owner> Owner_ = m.entity(Owner.class);

Root<Pet> pet = cq.from(Pet.class);
Join<Owner, Address> address = cq.join(Pet_.owners).join(Owner_.addresses);

That being said, I have some additional remarks:

First, the following line in your code:

Root entity_ = cq.from(this.baseClass);

Makes me think that you somehow missed the Static Metamodel Classes part. Metamodel classes such as Pet_ in the quoted example are used to describe the meta information of a persistent class. They are typically generated using an annotation processor (canonical metamodel classes) or can be written by the developer (non-canonical metamodel). But your syntax looks weird, I think you are trying to mimic something that you missed.

Second, I really think you should forget this assay_id foreign key, you're on the wrong path here. You really need to start to think object and association, not tables and columns.

Third, I'm not really sure to understand what you mean exactly by adding a JOIN clause as generical as possible and what your object model looks like, since you didn't provide it (see previous point). It's thus just impossible to answer your question more precisely.

To sum up, I think you need to read a bit more about JPA 2.0 Criteria and Metamodel API and I warmly recommend the resources below as a starting point.

You could use serialize

<input type="hidden" name="quotation[]" value="{{serialize($quotation)}}">

But best way in this case use the json_encode method in your blade and json_decode in controller.

Think differently, You can use the following library to convert pdf to image using javascript

If there are multiple certificates in a pfx file (key + corresponding certificate and a CA certificate) then this command worked well for me:

certutil -importpfx c:\somepfx.pfx this works but still a password is needed to be typed in manually for private key. Including -p and "password" cause error too many arguments for certutil on XP

There are a number of tools available which help debugging segmentation faults and I would like to add my favorite tool to the list: Address Sanitizers (often abbreviated ASAN).

Modern¹ compilers come with the handy -fsanitize=address flag, adding some compile time and run time overhead which does more error checking.

According to the documentation these checks include catching segmentation faults by default. The advantage here is that you get a stack trace similar to gdb's output, but without running the program inside a debugger. An example:

int main() {
  volatile int *ptr = (int*)0;
  *ptr = 0;
}

$ gcc -g -fsanitize=address main.c
$ ./a.out
AddressSanitizer:DEADLYSIGNAL

==4848==ABORTING

The output is slightly more complicated than what gdb would output but there are upsides:

• There is no need to reproduce the problem to receive a stack trace. Simply enabling the flag during development is enough.

• ASANs catch a lot more than just segmentation faults. Many out of bounds accesses will be caught even if that memory area was accessible to the process.

¹ That is Clang 3.1+ and GCC 4.8+.

Try something like this:

public class test 
{  

    public static void main(String a[])
    {  
        long tmp = 1346524199000;  

        Date d = new Date(tmp);  
        System.out.println(d);  
    }  
} 

In your component's template you can use multiple arguments by separating them with colons:

{{ myData | myPipe: 'arg1':'arg2':'arg3'... }}

From your code it will look like this:

new MyPipe().transform(myData, arg1, arg2, arg3)

And in your transform function inside your pipe you can use the arguments like this:

export class MyPipe implements PipeTransform { 
    // specify every argument individually   
    transform(value: any, arg1: any, arg2: any, arg3: any): any { }
    // or use a rest parameter
    transform(value: any, ...args: any[]): any { }
}

Beta 16 and before (2016-04-26)

Pipes take an array that contains all arguments, so you need to call them like this:

new MyPipe().transform(myData, [arg1, arg2, arg3...])

And your transform function will look like this:

export class MyPipe implements PipeTransform {    
    transform(value:any, args:any[]):any {
        var arg1 = args[0];
        var arg2 = args[1];
        ...
    }
}

Warning! chrome.tabs.getSelected is deprecated. Please use chrome.tabs.query as shown in the other answers.

First, you've to set the permissions for the API in manifest.json:

"permissions": [
    "tabs"
]

And to store the URL :

chrome.tabs.getSelected(null,function(tab) {
    var tablink = tab.url;
});

You can use MySQL Table Data Import Wizard

<table border="1px">

    <tr>
        <th>Student Name</th>
        <th>Email</th>
        <th>password</th>
    </tr>

        <?php

            If(mysql_num_rows($result)>0)
            {
                while($rows=mysql_fetch_array($result))
                {  

        ?>
    <?php echo "<tr>";?>
                    <td><?php echo $rows['userName'];?> </td>
                    <td><?php echo $rows['email'];?></td>
                    <td><?php echo $rows['password'];?></td>

    <?php echo "</tr>";?>
        <?php
                }
            }

    ?>
</table>
    <?php
        }
    ?>

Here's a version where the array keys may not be the same for both arrays, but you want them all to be there in the final array.

function array_add_by_key( $array1, $array2 ) {
    foreach ( $array2 as $k => $a ) {
        if ( array_key_exists( $k, $array1 ) ) {
            $array1[$k] += $a;
        } else {
            $array1[$k] = $a;
        }
    }
    return $array1;
}

Option 1: Go to Android SDK Folder --> Extra --> Intel and double click on HAXM installer and install it manually.

Option 2: If you do not have latest version of HAXM then you can open sdk manager in android studio and download it.

Option 3: Download HAXM intaller from Intel site. https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager

For Select2 4.X

var instance = $('#select2Container').data('select2');
var searchVal = instance.dropdown.$search.val();
instance.trigger('query', {term:searchVal});

environment.plst file loads first on MAC so put the path on it.

For 1st time use, use the following command

export PATH=$PATH: /path/to/set

You can try using groovy. It runs on the JVM and it comes with great support for running external processes and extracting the output:

http://groovy.codehaus.org/Executing+External+Processes+From+Groovy

You can see in this code taken from the same link how groovy makes it easy to get the status of the process:

println "return code: ${ proc.exitValue()}"
println "stderr: ${proc.err.text}"
println "stdout: ${proc.in.text}" // *out* from the external program is *in* for groovy

// CHANGE name="select2" TO name="select2[]" THEN
<?php
  $mySelection = $_GET['select2'];

  $nSelection = count($MySelection);

  for($i=0; $i < $nSelection; $i++)
   {
      $numberVal = $MySelection[$i];

        if ($numberVal == "11"){
         echo("Eleven"); 
         }
        else if ($numberVal == "12"){
         echo("Twelve"); 
         } 
         ...

         ...
    }
?>

If you have 2 installations of the JVM. Place the version upfront. Linux : export PATH=/usr/lib/jvm/java-8-oracle/bin:$PATH

This eliminates the ambiguity.

I got this error today whilst trying to initiate a slide effect on a div. Thanks to the answer from 'I Hate Lazy' above (which I've upvoted), I went looking for a custom jQuery UI script, and you can in fact build your own file directly on the jQuery ui website http://jqueryui.com/download/. All you have to do is mark the effect(s) that you're looking for and then download.

I was looking for the slide effect. So I first unchecked all the checkboxes, then clicked on the 'slide effect' checkbox and the page automatically then checks those other components necessary to make the slide effect work. Very simple.

easeOutBounce is an easing effect, for which you'll need to check the 'Effects Core' checkbox.

1. You shouldn't use Thread.Abort()
2. Tasks can be Cancelled but not aborted.

The Thread.Abort() method is (severely) deprecated.

Both Threads and Tasks should cooperate when being stopped, otherwise you run the risk of leaving the system in a unstable/undefined state.

If you do need to run a Process and kill it from the outside, the only safe option is to run it in a separate AppDomain.

This answer is about .net 3.5 and earlier.

Thread-abort handling has been improved since then, a.o. by changing the way finally blocks work.

But Thread.Abort is still a suspect solution that you should always try to avoid.

Create the user with a password :

http://www.postgresql.org/docs/current/static/sql-createuser.html

CREATE USER name [ [ WITH ] option [ ... ] ]

where option can be:

      SUPERUSER | NOSUPERUSER
    | CREATEDB | NOCREATEDB
    | CREATEROLE | NOCREATEROLE
    | CREATEUSER | NOCREATEUSER
    | INHERIT | NOINHERIT
    | LOGIN | NOLOGIN
    | REPLICATION | NOREPLICATION
    | CONNECTION LIMIT connlimit
    | [ ENCRYPTED | UNENCRYPTED ] PASSWORD 'password'
    | VALID UNTIL 'timestamp'
    | IN ROLE role_name [, ...]
    | IN GROUP role_name [, ...]
    | ROLE role_name [, ...]
    | ADMIN role_name [, ...]
    | USER role_name [, ...]
    | SYSID uid

Then grant the user rights on a specific database :

http://www.postgresql.org/docs/current/static/sql-grant.html

Example :

grant all privileges on database db_name to someuser;

I've had the same issue every now and then. This is how i solve the issue, it works like a charm for me!

1. Go to 'Task Manager'
2. Choose 'Processes' tab
3. Click on 'Java(TM) Platform SE Binary'
4. Click on 'End Process' button
5. Go to your NetBeans project
6. Clean & Build the project

how about using IN

DELETE FROM tableName
WHERE ID IN (1,2) -- add as many ID as you want.

This could also occur if you refer to a variable in the data.frame that doesn't exist. For example, recently I forgot to tell ddply to summarize by one of my variables that I used in geom_line to specify line color. Then, ggplot didn't know where to find the variable I hadn't created in the summary table, and I got this error.

How about access?

#include <io.h>

if (_access(filename, 0) == -1)
{
    // File does not exist
}

$(document).ready(function() {
            $(".clickable").click(function() {
                var userID = $(this).attr('id'); // you can add here your personal ID
                //alert($(this).attr('id'));
                $.ajax({
                    type: "POST",
                    url: 'logtime.php',
                    data : {
                        action : 'my_action',
                        userID : userID 
                    },
                    success: function(data)
                    {
                        alert("success!");
                        console.log(data);
                    }
                });
            });
        });


 $uid = (isset($_POST['userID'])) ? $_POST['userID'] : 'ID not found';
 echo $uid;

$uid add in your functions

note: if $ is not supperted than add jQuery where $ defined

I also faced the similar problem. I googled but couldn't find the solution. So I tried on my own and here is my solution.

Open you solution file in notepad. Make 2 changes

1. Replace "Format Version 12.00" with "Format Version 11.00" (without quotes.)
2. Replace "# Visual Studio 2012" with "# Visual Studio 2010" (without quotes.)

Hope this helps u as well..........

The general Angular way to get access to an element that triggered an event is to write a directive and bind() to the desired event:

app.directive('myChange', function() {
  return function(scope, element) {
    element.bind('change', function() {
      alert('change on ' + element);
    });
  };
});

or with DDO (as per @tpartee's comment below):

app.directive('myChange', function() {
  return { 
    link:  function link(scope, element) {
      element.bind('change', function() {
        alert('change on ' + element);
      });
    }
  }
});

The above directive can be used as follows:

<input id="searchText" ng-model="searchText" type="text" my-change>

Plunker.

Type into the text field, then leave/blur. The change callback function will fire. Inside that callback function, you have access to element.

Some built-in directives support passing an $event object. E.g., ng-*click, ng-Mouse*. Note that ng-change does not support this event.

Although you can get the element via the $event object:

<button ng-click="clickit($event)">Hello</button>

$scope.clickit = function(e) {
    var elem = angular.element(e.srcElement);
    ...

this goes "deep against the Angular way" -- Misko.

You could use moment.js with Postman to give you that timestamp format.

You can add this to the pre-request script:

const moment = require('moment');
pm.globals.set("today", moment().format("MM/DD/YYYY"));

Then reference {{today}} where ever you need it.

If you add this to the Collection Level Pre-request Script, it will be run for each request in the Collection. Rather than needing to add it to all the requests individually.

For more information about using moment in Postman, I wrote a short blog post: https://dannydainton.com/2018/05/21/hold-on-wait-a-moment/

ES6 Style

Math.min(...[0, 6].map(v => new Date(95, v, 1).getTimezoneOffset() * -1));

Swift 4 with saving array types

extension Array {
    func take(_ elementsCount: Int) -> [Element] {
        let min = Swift.min(elementsCount, count)
        return Array(self[0..<min])
    }
}

All of these answers unfortunately miss the point.

There are 2 security context nuances here, and we need them to overlap. - "Run as administrator" - changing your execution level on your local machine - "Run as different user" - selects what user credentials you run the process under.

When UAC is enabled on a workstation, there are processes which refuse to run unless elevated - simply being a member of the local "Administrators" group isn't enough. If your requirement also dictates that you use alternate credentials to those you are signed in with, we need a method to invoke the process both as the alternate credentials AND elevated.

What I found can be used, though a bit of a hassle, is:

• run a CMD prompt as administrator

• use the Sysinternals psexec utility as follows:

  psexec \\localworkstation -h -i -u domain\otheruser exetorun.exe

The first elevation is needed to be able to push the psexec service. The -h runs the new "remote" (local) process elevated, and -i lets it interact with the desktop.

Perhaps there are easier ways than this?

I m invoking the weighted average through reflection. And had used method with more than one parameter.

Class cls = Class.forName(propFile.getProperty(formulaTyp));// reading class name from file

Object weightedobj = cls.newInstance(); // invoke empty constructor

Class<?>[] paramTypes = { String.class, BigDecimal[].class, BigDecimal[].class }; // 3 parameter having first is method name and other two are values and their weight
Method printDogMethod = weightedobj.getClass().getMethod("applyFormula", paramTypes); // created the object 
return BigDecimal.valueOf((Double) printDogMethod.invoke(weightedobj, formulaTyp, decimalnumber, weight)); calling the method

The zip() function in Python 3 returns an iterator. That is the reason why when you print test1 you get - <zip object at 0x1007a06c8>. From documentation -

Make an iterator that aggregates elements from each of the iterables.

But once you do - list(test1) - you have exhausted the iterator. So after that anytime you do list(test1) would only result in empty list.

In case of test2, you have already created the list once, test2 is a list, and hence it will always be that list.

{% if variable is defined %} works to check if something is undefined.

You can get away with using {% if not var1 %} if you default your variables to False eg

class MainHandler(BaseHandler):
    def get(self):
        var1 = self.request.get('var1', False)
