This worked for me Visual C++ Redistributable Packages

Only static functions are called with class name.

classname::Staicfunction();

Non static functions have to be called using objects.

classname obj;
obj.Somefunction();

This is exactly what your error means. Since your function is non static you have to use a object reference to invoke it.

There is but one difference. You have to take care or name mangling win C++. But on windows you have to take care about 1) decrating the functions to be exported from the DLL 2) write a so called .def file which lists all the exported symbols.

In Windows while compiling a DLL have have to use

__declspec(dllexport)

but while using it you have to write __declspec(dllimport)

So the usual way of doing that is something like

#ifdef BUILD_DLL
#define EXPORT __declspec(dllexport)
#else
#define EXPORT __declspec(dllimport)
#endif

The naming is a bit confusing, because it is often named EXPORT.. But that's what you'll find in most of the headers somwhere. So in your case you'd write (with the above #define)

int DLL_EXPORT add.... int DLL_EXPORT mult...

Remember that you have to add the Preprocessor directive BUILD_DLL during building the shared library.

If you want plain C exports, use a C project not C++. C++ DLLs rely on name-mangling for all the C++isms (namespaces etc...). You can compile your code as C by going into your project settings under C/C++->Advanced, there is an option "Compile As" which corresponds to the compiler switches /TP and /TC.

If you still want to use C++ to write the internals of your lib but export some functions unmangled for use outside C++, see the second section below.

Exporting/Importing DLL Libs in VC++

What you really want to do is define a conditional macro in a header that will be included in all of the source files in your DLL project:

#ifdef LIBRARY_EXPORTS
#    define LIBRARY_API __declspec(dllexport)
#else
#    define LIBRARY_API __declspec(dllimport)
#endif

Then on a function that you want to be exported you use LIBRARY_API:

LIBRARY_API int GetCoolInteger();

In your library build project create a define LIBRARY_EXPORTS this will cause your functions to be exported for your DLL build.

Since LIBRARY_EXPORTS will not be defined in a project consuming the DLL, when that project includes the header file of your library all of the functions will be imported instead.

If your library is to be cross-platform you can define LIBRARY_API as nothing when not on Windows:

#ifdef _WIN32
#    ifdef LIBRARY_EXPORTS
#        define LIBRARY_API __declspec(dllexport)
#    else
#        define LIBRARY_API __declspec(dllimport)
#    endif
#elif
#    define LIBRARY_API
#endif

When using dllexport/dllimport you do not need to use DEF files, if you use DEF files you do not need to use dllexport/dllimport. The two methods accomplish the same task different ways, I believe that dllexport/dllimport is the recommended method out of the two.

Exporting unmangled functions from a C++ DLL for LoadLibrary/PInvoke

If you need this to use LoadLibrary and GetProcAddress, or maybe importing from another language (i.e PInvoke from .NET, or FFI in Python/R etc) you can use extern "C" inline with your dllexport to tell the C++ compiler not to mangle the names. And since we are using GetProcAddress instead of dllimport we don't need to do the ifdef dance from above, just a simple dllexport:

The Code:

#define EXTERN_DLL_EXPORT extern "C" __declspec(dllexport)

EXTERN_DLL_EXPORT int getEngineVersion() {
  return 1;
}

EXTERN_DLL_EXPORT void registerPlugin(Kernel &K) {
  K.getGraphicsServer().addGraphicsDriver(
    auto_ptr<GraphicsServer::GraphicsDriver>(new OpenGLGraphicsDriver())
  );
}

And here's what the exports look like with Dumpbin /exports:

  Dump of file opengl_plugin.dll

  File Type: DLL

  Section contains the following exports for opengl_plugin.dll

    00000000 characteristics
    49866068 time date stamp Sun Feb 01 19:54:32 2009
        0.00 version
           1 ordinal base
           2 number of functions
           2 number of names

    ordinal hint RVA      name

          1    0 0001110E getEngineVersion = @ILT+265(_getEngineVersion)
          2    1 00011028 registerPlugin = @ILT+35(_registerPlugin)

So this code works fine:

m_hDLL = ::LoadLibrary(T"opengl_plugin.dll");

m_pfnGetEngineVersion = reinterpret_cast<fnGetEngineVersion *>(
  ::GetProcAddress(m_hDLL, "getEngineVersion")
);
m_pfnRegisterPlugin = reinterpret_cast<fnRegisterPlugin *>(
  ::GetProcAddress(m_hDLL, "registerPlugin")
);

this worked for me though... i wanted to display the image after the pencil icon is being clicked... and i wanted it seamless.. and this was my approach..

i created an input[file] element and made it hidden,

<input type="file" id="upl" style="display:none"/>

this input-file's click event will be trigged by the getImage function.

<a href="javascript:;" onclick="getImage()"/>
    <img src="/assets/pen.png"/>
</a>

<script>
     function getImage(){
       $('#upl').click();
     }
</script>

this is done while listening to the change event of the input-file element with ID of #upl.

   $(document).ready(function(){_x000D_
     _x000D_
       $('#upl').bind('change', function(evt){_x000D_
         _x000D_
    var preview = $('#logodiv').find('img');_x000D_
    var file    = evt.target.files[0];_x000D_
    var reader  = new FileReader();_x000D_
  _x000D_
    reader.onloadend = function () {_x000D_
   $('#logodiv > img')_x000D_
    .prop('src',reader.result)  //set the scr prop._x000D_
    .prop('width', 216);  //set the width of the image_x000D_
    .prop('height',200);  //set the height of the image_x000D_
    }_x000D_
  _x000D_
    if (file) {_x000D_
   reader.readAsDataURL(file);_x000D_
    } else {_x000D_
   preview.src = "";_x000D_
    }_x000D_
  _x000D_
    });_x000D_
_x000D_
   })

and BOOM!!! - it WORKS....

Swanand's answer is great.

if you are using FactoryGirl, you can use its build method to generate the attribute hash without the key id. e.g.

VMWare Player can be seen as a free, closed-source competitor to Virtualbox.

Initially VMWare Player (up to version 2.5) was intended to operate on fixed virtual operating systems (e.g. play back pre-created virtual disks).

Many advanced features such as vsphere are probably not required by most users, and VMWare Player will provide the same core technologies and 3D acceleration as the ESX Workstation solution.

From my experience VMWare Player 5 is faster than Virtualbox 4.2 RC3 and has better SMP performance. Both are great however, each with its own unique advantages. Both are somewhat lacking in 2D rendering performance.

See the official FAQ, and a feature comparison table.

You need to reference the namespace

using System.Windows.Form;

and then add in the code

protected void Button1_Click(object sender, EventArgs e)
    {
        MessageBox.Show(" Hi....");

    }

It might be safer to directly pass environment variables to maven system properties. For example, say on Linux you want to access environment variable MY_VARIABLE. You can use a system property in your pom file.

<properties>
    ...
    <!-- Default value for my.variable can be defined here -->
    <my.variable>foo</my.variable>
    ...
</properties>
...
<!-- Use my.variable -->
... ${my.variable} ...

Set the property value on the maven command line:

mvn clean package -Dmy.variable=$MY_VARIABLE

Follow @reVerse answer but in my case, I already had some property in my AppTheme like

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    ...
    <item name="android:textColor">#111</item>
    <item name="android:textSize">13sp</item>
</style>

So my dialog will look like

I solved it by

1) Change the import from android.app.AlertDialog to android.support.v7.app.AlertDialog
2) I override 2 property in AppTheme with null value

<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    <!-- Used for the buttons -->
    <item name="colorAccent">#FFC107</item>
    <!-- Used for the title and text -->
    <item name="android:textColorPrimary">#FFFFFF</item>
    <!-- Used for the background -->
    <item name="android:background">#4CAF50</item>


    <item name="android:textColor">@null</item>
    <item name="android:textSize">@null</item>
</style>

.

AlertDialog.Builder builder = new AlertDialog.Builder(mContext, R.style.MyAlertDialogStyle);

Hope it help another people

Building on the solution provided I thought it might be helpful to show an example passing your own custom data object (which I've referenced here as 'message' as per question).

Class A (sender):

YourDataObject *message = [[YourDataObject alloc] init];
// set your message properties
NSDictionary *dict = [NSDictionary dictionaryWithObject:message forKey:@"message"];
[[NSNotificationCenter defaultCenter] postNotificationName:@"NotificationMessageEvent" object:nil userInfo:dict];

Class B (receiver):

- (void)viewDidLoad
{
    [super viewDidLoad];
    [[NSNotificationCenter defaultCenter]
     addObserver:self selector:@selector(triggerAction:) name:@"NotificationMessageEvent" object:nil];
}

#pragma mark - Notification
-(void) triggerAction:(NSNotification *) notification
{
    NSDictionary *dict = notification.userInfo;
    YourDataObject *message = [dict valueForKey:@"message"];
    if (message != nil) {
        // do stuff here with your message data
    }
}

You can generate scripts to a file via SQL Server Management Studio, here are the steps:

1. Right click the database you want to generate scripts for (not the table) and select tasks - generate scripts
2. Next, select the requested table/tables, views, stored procedures, etc (from select specific database objects)
3. Click advanced - select the types of data to script
4. Click Next and finish

MSDN Generate Scripts

When generating the scripts, there is an area that will allow you to script, constraints, keys, etc. From SQL Server 2008 R2 there is an Advanced Option under scripting:

You should check for the type of the item in the localStorage

if(localStorage.token !== null) {
   // this will only work if the token is set in the localStorage
}

if(typeof localStorage.token !== 'undefined') {
  // do something with token
}

if(typeof localStorage.token === 'undefined') {
  // token doesn't exist in the localStorage, maybe set it?
}

In my case junk files from editor caused the problem. I had a config as below:

#...
http {
 # ...
 include ../sites/*;
}

In the ../sites directory initially I had a default.config file. However, by mistake I saved duplicate files as default.config.save and default.config.save.1. Removing them resolved the issue.

echo -n works and is unlikely to ever disappear due to massive historical usage, however per recent versions of the POSIX standard, new conforming applications are "encouraged to use printf".

A signed char is a signed value which is typically smaller than, and is guaranteed not to be bigger than, a short. An unsigned char is an unsigned value which is typically smaller than, and is guaranteed not to be bigger than, a short. A type char without a signed or unsigned qualifier may behave as either a signed or unsigned char; this is usually implementation-defined, but there are a couple of cases where it is not:

1. If, in the target platform's character set, any of the characters required by standard C would map to a code higher than the maximum `signed char`, then `char` must be unsigned.
2. If `char` and `short` are the same size, then `char` must be signed.

Part of the reason there are two dialects of "C" (those where char is signed, and those where it is unsigned) is that there are some implementations where char must be unsigned, and others where it must be signed.

How about

List<object> collection = new List<object>((IEnumerable)myObject);

This is for fecha(TEXT) format date YYYY-MM-dd HH:mm:ss for instance I want all the records of Ene-05-2014 (2014-01-05):

SELECT 
 fecha 
FROM 
 Mytable 
WHERE 
 DATE(substr(fecha ,1,4) ||substr(fecha ,6,2)||substr(fecha ,9,2))
BETWEEN 
 DATE(20140105) 
AND 
 DATE(20140105);

To use native Python directories, use:

import subprocess

def copy2clip(txt):
    cmd='echo '+txt.strip()+'|clip'
    return subprocess.check_call(cmd, shell=True)

on Mac, instead:

import subprocess

def copy2clip(txt):
    cmd='echo '+txt.strip()+'|pbcopy'
    return subprocess.check_call(cmd, shell=True)

Then use:

copy2clip('This is on my clipboard!')

to call the function.

Late to the party, but I think this is actually the most elegant. Use the WORD JOINER Unicode character ⁠ on either side of your hyphen, or em dash, or any character.

So, like so:

⁠—⁠

This will join the symbol on both ends to its neighbors (without adding a space) and prevent line breaking.

There is a whole page in the MATLAB documentation dedicated to this topic: Array vs. Matrix Operations. The gist of it is below:

MATLAB® has two different types of arithmetic operations: array operations and matrix operations. You can use these arithmetic operations to perform numeric computations, for example, adding two numbers, raising the elements of an array to a given power, or multiplying two matrices.

Matrix operations follow the rules of linear algebra. By contrast, array operations execute element by element operations and support multidimensional arrays. The period character (.) distinguishes the array operations from the matrix operations. However, since the matrix and array operations are the same for addition and subtraction, the character pairs .+ and .- are unnecessary.

string output = input.Substring(input.IndexOf('(') + 1, input.IndexOf(')') - input.IndexOf('(') - 1);

Obviously, Class.isAssignableFrom() tells you whether an individual class implements the given interface. So then the problem is getting the list of classes to test.

As far as I'm aware, there's no direct way from Java to ask the class loader for "the list of classes that you could potentially load". So you'll have to do this yourself by iterating through the visible jars, calling Class.forName() to load the class, then testing it.

However, it's a little easier if you just want to know classes implementing the given interface from those that have actually been loaded:

• via the Java Instrumentation framework, you can call Instrumentation.getAllLoadedClasses()
• via reflection, you can query the ClassLoader.classes field of a given ClassLoader.

If you use the instrumentation technique, then (as explained in the link) what happens is that your "agent" class is called essentially when the JVM starts up, and passed an Instrumentation object. At that point, you probably want to "save it for later" in a static field, and then have your main application code call it later on to get the list of loaded classes.

The urls are different.

• http://localhost/AccountSvc/DataInquiry.asmx

vs.

• /acctinqsvc/portfolioinquiry.asmx

Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.

You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx, and specify the desired method/operation in the SOAPAction header.

The SOAPAction header values are different.

• http://localhost/AccountSvc/DataInquiry.asmx/ + methodName

vs.

• http://tempuri.org/GetMyName

You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl

There should be a <soap:operation> tag underneath the <wsdl:operation> tag that matches the operation you are attempting to execute, which appears to be GetMyName.

There is no XML declaration in the request body that includes your SOAP XML.

You specify text/xml in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii, but there's no telling if you aren't specifying them!

The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8

Hope that helps!

I always use the tag. It is a simple compile-time flag to catch little mistakes that I might make.

It will catch things like tostring() instead of toString()

The little things help in large projects.

Java is not finding where your compiled class file (HelloWorld.class) is. It uses the directories and JAR-files in the CLASSPATH environment variable for searching if no -cp or -classpath option is given when running java.exe.

You don't need the rt.jar in the CLASSPATH, these was only needed for older versions of Java. You can leave it undefined and the current working directory will be used, or just add . (a single point), separated by ';', to the CLASSPATH variable to indicate the current directory:

CLASSPATH: .;C:\...\some.jar

Alternatively you can use the -cp or -classpath option:

java -cp . HelloWorld

And, as Andreas wrote, JAVA_HOME is not needed by Java, just for some third-party tools like ant (but should point to the correct location).

I can see you said you didn't want to use mysqldump, but I reached this page while looking for a similar solution and others might find it as well. With that in mind, here is a simple way to duplicate a database from the command line of a windows server:

1. Create the target database using MySQLAdmin or your preferred method. In this example, db2 is the target database, where the source database db1 will be copied.
2. Execute the following statement on a command line:

mysqldump -h [server] -u [user] -p[password] db1 | mysql -h [server] -u [user] -p[password] db2

Note: There is NO space between -p and [password]

SELECT utl_raw.cast_to_varchar2(dbms_lob.substr(<YOUR_BLOB_FIELD>,2000,1)) FROM <YOUR_TABLE>;

Note: This is because, Oracle will not be able to handle the conversion of BLOB that is more than length 2000.

No need to type in the password, just use any one of these commands (self explanatory):

mysqlcheck --all-databases -a #analyze
mysqlcheck --all-databases -r #repair
mysqlcheck --all-databases -o #optimize

You can use the following to get the root directory of a website project:

String FilePath;
FilePath = Server.MapPath("/MyWebSite");

Or you can get the base directory like so:

AppDomain.CurrentDomain.BaseDirectory

Eduardo Molteni had a great answer:

• SQL Server Automated Backups

Using Windows Scheduled Tasks:

In the batch file

"C:\Program Files\Microsoft SQL Server\100\Tools\Binn\SQLCMD.EXE" -S 
(local)\SQLExpress -i D:\dbbackups\SQLExpressBackups.sql

In SQLExpressBackups.sql

BACKUP DATABASE MyDataBase1 TO  DISK = N'D:\DBbackups\MyDataBase1.bak' 
WITH NOFORMAT, INIT,  NAME = N'MyDataBase1 Backup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10

BACKUP DATABASE MyDataBase2 TO  DISK = N'D:\DBbackups\MyDataBase2.bak' 
WITH NOFORMAT, INIT,  NAME = N'MyDataBase2 Backup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10

GO

you may try this way also, it will provide you material style dialogs

private void showDialog()
{
    String text2 = "<font color=#212121>Medi Notification</font>";//for custom title color

    AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.AppCompatAlertDialogStyle);
    builder.setTitle(Html.fromHtml(text2));

    String text3 = "<font color=#A4A4A4>You can complete your profile now or start using the app and come back later</font>";//for custom message
    builder.setMessage(Html.fromHtml(text3));

    builder.setPositiveButton("DELETE", new DialogInterface.OnClickListener()
    {
        @Override
        public void onClick(DialogInterface dialog, int which)
        {
            toast = Toast.makeText(getApplicationContext(), "DELETE", Toast.LENGTH_SHORT);
            toast.setGravity(Gravity.CENTER, 0, 0);
            toast.show();              
        }
    });

    builder.setNegativeButton("CANCEL", new DialogInterface.OnClickListener()
    {
        @Override
        public void onClick(DialogInterface dialog, int which)
        {
            toast = Toast.makeText(getApplicationContext(), "CANCEL", Toast.LENGTH_SHORT);
            toast.setGravity(Gravity.CENTER, 0, 0);
            toast.show();
        }
    });
    builder.show();
}

For another instance of Glibc, download gcc 4.7.2, for instance from this github repo (although an official source would be better) and extract it to some folder, then update LD_LIBRARY_PATH with the path where you have extracted glib.

export LD_LIBRARY_PATH=$glibpath/glib-2.49.4-kgesagxmtbemim2denf65on4iixy3miy/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$glibpath/libffi-3.2.1-wk2luzhfdpbievnqqtu24pi774esyqye/lib64:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$glibpath/pcre-8.39-itdbuzevbtzqeqrvna47wstwczud67wx/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$glibpath/gettext-0.19.8.1-aoweyaoufujdlobl7dphb2gdrhuhikil/lib:$LD_LIBRARY_PATH

*Disclaimer: I just completed the thought it looks like the OP was trying to express, but I don't fully agree.

You may also want to add

table td { border:0; }

the above is equivalent to setting cellpadding="0"

it gets rid of the padding automatically added to cells by browsers which may depend on doctype and/or any CSS used to reset default browser styles

This is a very straightforward solution that I came up with after following conca's link and looking at background size. It blows the image up and then fits it centered into the outer container w/o scaling it.

<style>
#cropcontainer
{
  width:  100%; 
  height: 100%; 
  background-size: 140%;
  background-position: center;
  background-repeat: no-repeat;
}
</style>

<div id="cropcontainer" style="background-image: url(yoururl); />

I'm going to add my 2 cents in case someone finds himself in a position like mine. I too was looking for an MVC project type and could not see it. All I saw is a "Web Application Project". So I freaked out and rushed into trying all solutions listed on this page.

But.

IT IS ACTUALLY THERE.

Just go with the "Web application" project and it will give you the MVC option on the next step.

IE 9 : If you want that the user takes a look at image before he posts it to the server : The user should ADD the website to "trusted Website list".

To get a random 3-digit number:

from random import randint
randint(100, 999)  # randint is inclusive at both ends

(assuming you really meant three digits, rather than "up to three digits".)

To use an arbitrary number of digits:

from random import randint

def random_with_N_digits(n):
    range_start = 10**(n-1)
    range_end = (10**n)-1
    return randint(range_start, range_end)

print random_with_N_digits(2)
print random_with_N_digits(3)
print random_with_N_digits(4)

Output:

33
124
5127

What it is:

%0|%0 is a fork bomb. It will spawn another process using a pipe | which runs a copy of the same program asynchronously. This hogs the CPU and memory, slowing down the system to a near-halt (or even crash the system).

How this works:

%0 refers to the command used to run the current program. For example, script.bat

A pipe | symbol will make the output or result of the first command sequence as the input for the second command sequence. In the case of a fork bomb, there is no output, so it will simply run the second command sequence without any input.

Expanding the example, %0|%0 could mean script.bat|script.bat. This runs itself again, but also creating another process to run the same program again (with no input).

You don't want multipart, but a "plain" POST request (with Content-Type: application/json) instead. Here is all you need:

var request = require('request');

var requestData = {
  request: {
    slice: [
      {
        origin: "ZRH",
        destination: "DUS",
        date: "2014-12-02"
      }
    ],
    passengers: {
      adultCount: 1,
      infantInLapCount: 0,
      infantInSeatCount: 0,
      childCount: 0,
      seniorCount: 0
    },
    solutions: 2,
    refundable: false
  }
};

request('https://www.googleapis.com/qpxExpress/v1/trips/search?key=myApiKey',
        { json: true, body: requestData },
        function(err, res, body) {
  // `body` is a js object if request was successful
});

An advantage that isn't listed yet is the ability of mmap() to keep a read-only mapping as clean pages. If one allocates a buffer in the process's address space, then uses read() to fill the buffer from a file, the memory pages corresponding to that buffer are now dirty since they have been written to.

Dirty pages can not be dropped from RAM by the kernel. If there is swap space, then they can be paged out to swap. But this is costly and on some systems, such as small embedded devices with only flash memory, there is no swap at all. In that case, the buffer will be stuck in RAM until the process exits, or perhaps gives it back withmadvise().

Non written to mmap() pages are clean. If the kernel needs RAM, it can simply drop them and use the RAM the pages were in. If the process that had the mapping accesses it again, it cause a page fault the kernel re-loads the pages from the file they came from originally. The same way they were populated in the first place.

This doesn't require more than one process using the mapped file to be an advantage.

You can't use php code client-side. You need to use javascript.

<input type="button" value="Home" class="homebutton" id="btnHome" 
onClick="document.location.href='some/page'" />

However, you really shouldn't be using inline js (like onclick here). Study about this here: https://www.google.com/search?q=Why+is+inline+js+bad%3F

Here's a clean way of doing this: Live demo (click).

Markup:

<button id="myBtn">Redirect</button>

JavaScript:

var btn = document.getElementById('myBtn');
btn.addEventListener('click', function() {
  document.location.href = 'some/page';
});

If you need to write in the location with php:

  <button id="myBtn">Redirect</button>
  <script>
    var btn = document.getElementById('myBtn');
    btn.addEventListener('click', function() {
      document.location.href = '<?php echo $page; ?>';
    });
  </script>

really this belongs as a comment to Nathan's answer, but I'm not allowed to do that yet...
I wanted to maintain the aspect ratio, even if there is too much stuff to fit in the box. His example expands the height, changing the aspect ratio. I found adding

overflow: hidden;
overflow-x: auto;
overflow-y: auto;

to the .element helped. See http://jsfiddle.net/B8FU8/3111/

The :before pseudo element isn't needed for the clearfix hack itself.

It's just an additional nice feature helping to prevent margin-collapsing of the first child element. Thus the top margin of an child block element of the "clearfixed" element is guaranteed to be positioned below the top border of the clearfixed element.

display:table is being used because display:block doesn't do the trick. Using display:block margins will collapse even with a :before element.

There is one caveat: if vertical-align:baseline is used in table cells with clearfixed <div> elements, Firefox won't align well. Then you might prefer using display:block despite loosing the anti-collapsing feature. In case of further interest read this article: Clearfix interfering with vertical-align.

This is what I use to collect single frames, but if you modify this and keep the two targets open all the time then you could "stream" it to disk using a static counter for the file name. - I can't recall where I found this, but it has been modified, thanks to whoever!

I was having the same problem. It seems that passing Me.ComboBox1.Value as an argument for the Vlookup function is causing the issue. What I did was assign this value to a double and then put it into the Vlookup function.

Dim x As Double
x = Me.ComboBox1.Value
Me.TextBox1.Value = Application.WorksheetFunction.VLookup(x, Worksheets("Sheet3").Range("Names"), 2, False) 

Or, for a shorter method, you can just convert the type within the Vlookup function using Cdbl(<Value>).

So it would end up being

Me.TextBox1.Value = Application.WorksheetFunction.VLookup(Cdbl(Me.ComboBox1.Value), Worksheets("Sheet3").Range("Names"), 2, False) 

Strange as it may sound, it works for me.

Hope this helps.

Try with this:

It will provide you all user queries. Till spid 50,it's all are sql server internal process sessions. But, if you want you can remove where clause:

select
r.session_id,
r.start_time,
s.login_name,
c.client_net_address,
s.host_name,
s.program_name,
st.text
from sys.dm_exec_requests r
inner join sys.dm_exec_sessions s
on r.session_id = s.session_id
left join sys.dm_exec_connections c
on r.session_id = c.session_id
outer apply sys.dm_exec_sql_text(r.sql_handle) st where r.session_id  > 50

For Vb.Net Framework 4.0, U can use:

Alert("your message here", Boolean)

The Boolean here can be True or False. True If you want to close the window right after, False If you want to keep the window open.

This works very well for me. Go to the android-support-v7-appcompat project and open the file "project.properties" and insert this lines if missing:

target=android-25_x000D_
compile=android-21

For dict, just use

if key in dict

and don't use searching in key list

if key in dict.keys()

The latter will be more time-consuming.

If an abstract class is appropriate for your implementation, test (as suggested above) a derived concrete class. Your assumptions are correct.

To avoid future confusion, be aware that this concrete test class is not a mock, but a fake.

In strict terms, a mock is defined by the following characteristics:

• A mock is used in place of each and every dependency of the subject class being tested.
• A mock is a pseudo-implementation of an interface (you may recall that as a general rule, dependencies should be declared as interfaces; testability is one primary reason for this)
• Behaviors of the mock's interface members -- whether methods or properties -- are supplied at test-time (again, by use of a mocking framework). This way, you avoid coupling of the implementation being tested with the implementation of its dependencies (which should all have their own discrete tests).

The or and and python statements require truth-values. For pandas these are considered ambiguous so you should use "bitwise" | (or) or & (and) operations:

result = result[(result['var']>0.25) | (result['var']<-0.25)]

These are overloaded for these kind of datastructures to yield the element-wise or (or and).

Just to add some more explanation to this statement:

The exception is thrown when you want to get the bool of a pandas.Series:

>>> import pandas as pd
>>> x = pd.Series([1])
>>> bool(x)
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

What you hit was a place where the operator implicitly converted the operands to bool (you used or but it also happens for and, if and while):

>>> x or x
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
>>> x and x
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
>>> if x:
...     print('fun')
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
>>> while x:
...     print('fun')
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

Besides these 4 statements there are several python functions that hide some bool calls (like any, all, filter, ...) these are normally not problematic with pandas.Series but for completeness I wanted to mention these.

In your case the exception isn't really helpful, because it doesn't mention the right alternatives. For and and or you can use (if you want element-wise comparisons):

• numpy.logical_or:

  >>> import numpy as np
  >>> np.logical_or(x, y)
  

  or simply the | operator:

  >>> x | y
  

• numpy.logical_and:

  >>> np.logical_and(x, y)
  

  or simply the & operator:

  >>> x & y
  

If you're using the operators then make sure you set your parenthesis correctly because of the operator precedence.

There are several logical numpy functions which should work on pandas.Series.

The alternatives mentioned in the Exception are more suited if you encountered it when doing if or while. I'll shortly explain each of these:

• If you want to check if your Series is empty:

  >>> x = pd.Series([])
  >>> x.empty
  True
  >>> x = pd.Series([1])
  >>> x.empty
  False
  

  Python normally interprets the length of containers (like list, tuple, ...) as truth-value if it has no explicit boolean interpretation. So if you want the python-like check, you could do: if x.size or if not x.empty instead of if x.

• If your Series contains one and only one boolean value:

  >>> x = pd.Series([100])
  >>> (x > 50).bool()
  True
  >>> (x < 50).bool()
  False
  

• If you want to check the first and only item of your Series (like .bool() but works even for not boolean contents):

  >>> x = pd.Series([100])
  >>> x.item()
  100
  

• If you want to check if all or any item is not-zero, not-empty or not-False:

  >>> x = pd.Series([0, 1, 2])
  >>> x.all()   # because one element is zero
  False
  >>> x.any()   # because one (or more) elements are non-zero
  True
  

If you want to call the incremented number directly in a function, this solution works bettter:

Function inc(ByRef data As Integer)
    data = data + 1
    inc = data
End Function

for example:

Wb.Worksheets(mySheet).Cells(myRow, inc(myCol))

If the function inc() returns no value, the above line will generate an error.

Some great answers above, using that info here is what I did today to solve the same issue:

$to_array = explode(',', $to);
foreach($to_array as $address)
{
    $mail->addAddress($address, 'Web Enquiry');
}

Tagging of the image isn't supported inside the Dockerfile. This needs to be done in your build command. As a workaround, you can do the build with a docker-compose.yml that identifies the target image name and then run a docker-compose build. A sample docker-compose.yml would look like

version: '2'

services:
  man:
    build: .
    image: dude/man:v2

That said, there's a push against doing the build with compose since that doesn't work with swarm mode deploys. So you're back to running the command as you've given in your question:

docker build -t dude/man:v2 .

Personally, I tend to build with a small shell script in my folder (build.sh) which passes any args and includes the name of the image there to save typing. And for production, the build is handled by a ci/cd server that has the image name inside the pipeline script.

This code works for me:

public void Run()
{
    Dog myDog = new Dog();
    myDog.Name= "Foo";
    myDog.Color = DogColor.Brown;

    System.Console.WriteLine("{0}", myDog.ToString());

    MemoryStream stream = SerializeToStream(myDog);

    Dog newDog = (Dog)DeserializeFromStream(stream);

    System.Console.WriteLine("{0}", newDog.ToString());
}

Where the types are like this:

[Serializable]
public enum DogColor
{
    Brown,
    Black,
    Mottled
}

[Serializable]
public class Dog
{
    public String Name
    {
        get; set;
    }

    public DogColor Color
    {
        get;set;
    }

    public override String ToString()
    {
        return String.Format("Dog: {0}/{1}", Name, Color);
    }
}

and the utility methods are:

public static MemoryStream SerializeToStream(object o)
{
    MemoryStream stream = new MemoryStream();
    IFormatter formatter = new BinaryFormatter();
    formatter.Serialize(stream, o);
    return stream;
}

public static object DeserializeFromStream(MemoryStream stream)
{
    IFormatter formatter = new BinaryFormatter();
    stream.Seek(0, SeekOrigin.Begin);
    object o = formatter.Deserialize(stream);
    return o;
}

Chances are that you may be running your eclipse using Java 1.5.

Latest Plugin requires that the JRE be 1.6 or higher. 

You will have to use Eclipse that runs on JRE 1.6

Edit: I had run into same problems. If it is not JRE problem then you can debug this. Follow below procedure:

1. Window -> show View -> other -> Plugin Development -> Plugin Registry
2. In the plugin registry search for com.android.ide.eclipse.adt or any other plugin related to android (depending on your installation there maybe 7-8)
3. Select , Right Click -> Diagnose. This will show the problem why the plugin was not loaded

Coolection has not pretend to be the new lambda, however we're surrounded by old legacy Java projects where this lib will help. It's really simple to use and extend, covering only the most used actions of iteration over collections, like that:

from(people).where("name", eq("Arthur")).first();
from(people).where("age", lessThan(20)).all();
from(people).where("name", not(contains("Francine"))).all();

Your Ubuntu definitely has a sufficiently recent version of g++. The flag to use is -std=c++0x.

I assume you're talking about on the command-line - if it's in a script, then a new-line acts as a command delimiter.

On the command line, use a semi-colon ';'

In my case the database was running on non standard port. Check that the port you are connecting is the same as the port the database is running on. If there are more instances of SQL server, check the correct one.

Try figsize param in df.plot(figsize=(width,height)):

df = pd.DataFrame({"a":[1,2],"b":[1,2]})
df.plot(figsize=(3,3));

df = pd.DataFrame({"a":[1,2],"b":[1,2]})
df.plot(figsize=(5,3));

The size in figsize=(5,3) is given in inches per (width, height)

Additional to this answer, create a function like

CREATE FUNCTION myrandom(
    pmin INTEGER,
    pmax INTEGER
)
RETURNS INTEGER(11)
DETERMINISTIC
NO SQL
SQL SECURITY DEFINER
BEGIN
  RETURN floor(pmin+RAND()*(pmax-pmin));
END; 

and call like

SELECT myrandom(100,300);

This gives you random number between 100 and 300

String[] tblHead={"Item Name","Price","Qty","Discount"};
DefaultTableModel dtm=new DefaultTableModel(tblHead,0);
JTable tbl=new JTable(dtm);
String[] item={"A","B","C","D"};
dtm.addRow(item);

Here;this is the solution.

If all your divs start with editDialog as you stated, then you can use the following selector:

$("div[id^='editDialog']")

Or you could use a class selector instead if it's easier for you

<div id="editDialog-0" class="editDialog">...</div>

$(".editDialog")

As others have noted, it is usually preferable to specify a minimum logging level to log that level and any others more severe than it. It seems like you are just thinking about the logging levels backwards.

However, if you want more fine-grained control over logging individual levels, you can tell log4net to log only one or more specific levels using the following syntax:

<filter type="log4net.Filter.LevelMatchFilter">
  <levelToMatch value="WARN"/>
</filter>

Or to exclude a specific logging level by adding a "deny" node to the filter.

You can stack multiple filters together to specify multiple levels. For instance, if you wanted only WARN and FATAL levels. If the levels you wanted were consecutive, then the LevelRangeFilter is more appropriate.

Reference Doc: log4net.Filter.LevelMatchFilter

If the other answers haven't given you enough information, hopefully this will help you get what you want out of log4net.

The following should work for a JSON returned string. It will also work for an associative array of data.

for (var key in data)
     alert(key + ' is ' + data[key]);

You all seem to love complication. Just click on column(to select entire column), press and hold CTRL and click on cells that you want to exclude(C1 to C5 in you case). Now you have selected entire column C (right to the end of sheet) without starting cells. All you have to do now is to rightclick and "Define Name" for your selection(ex. asdf ). In formula you use SUM(asdf). And now you're done. Good luck

Allways find the easyest way ;)

Here's a C implementation of @Jean-Paul's Smoothed Z-score for the Arduino microcontroller used to take accelerometer readings and decide whether the direction of an impact has come from the left or the right. This performs really well since this device returns a bounced signal. Here's this input to this peak detection algorithm from the device - showing an impact from the right followed by and impact from the left. You can see the initial spike then the oscillation of the sensor.

Not great but here with influence = 1

which is very good.

When you execute a method (i.e. function assigned to an object), inside it you can use this variable to refer to this object, for example:

var obj = {_x000D_
  someProperty: true,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
obj.someMethod(); // logs true

If you assign a method from one object to another, its this variable refers to the new object, for example:

var obj = {_x000D_
  someProperty: true,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
_x000D_
var anotherObj = {_x000D_
  someProperty: false,_x000D_
  someMethod: obj.someMethod_x000D_
};_x000D_
_x000D_
anotherObj.someMethod(); // logs false

The same thing happens when you assign requestAnimationFrame method of window to another object. Native functions, such as this, has build-in protection from executing it in other context.

There is a Function.prototype.call() function, which allows you to call a function in another context. You just have to pass it (the object which will be used as context) as a first parameter to this method. For example alert.call({}) gives TypeError: Illegal invocation. However, alert.call(window) works fine, because now alert is executed in its original scope.

If you use .call() with your object like that:

support.animationFrame.call(window, function() {});

it works fine, because requestAnimationFrame is executed in scope of window instead of your object.

However, using .call() every time you want to call this method, isn't very elegant solution. Instead, you can use Function.prototype.bind(). It has similar effect to .call(), but instead of calling the function, it creates a new function which will always be called in specified context. For example:

window.someProperty = true;_x000D_
var obj = {_x000D_
  someProperty: false,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
_x000D_
var someMethodInWindowContext = obj.someMethod.bind(window);_x000D_
someMethodInWindowContext(); // logs true

The only downside of Function.prototype.bind() is that it's a part of ECMAScript 5, which is not supported in IE <= 8. Fortunately, there is a polyfill on MDN.

As you probably already figured out, you can use .bind() to always execute requestAnimationFrame in context of window. Your code could look like this:

var support = {
    animationFrame: (window.requestAnimationFrame ||
        window.mozRequestAnimationFrame ||
        window.webkitRequestAnimationFrame ||
        window.msRequestAnimationFrame ||
        window.oRequestAnimationFrame).bind(window)
};

Then you can simply use support.animationFrame(function() {});.

There are 2 calls that need to set the correct headers. Initially there is a preflight check so you need something like...

app.get('/item', item.list);
app.options('/item', item.preflight);

and then have the following functions...

exports.list = function (req, res) {
Items.allItems(function (err, items) {
    ...
        res.header('Access-Control-Allow-Origin', "*");     // TODO - Make this more secure!!
        res.header('Access-Control-Allow-Methods', 'GET,PUT,POST');
        res.header('Access-Control-Allow-Headers', 'Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept');
        res.send(items);
      }
   );
};

and for the pre-flight checks

exports.preflight = function (req, res) {
Items.allItems(function (err, items) {
        res.header('Access-Control-Allow-Origin', "*");     // TODO - Make this more secure!!
        res.header('Access-Control-Allow-Methods', 'GET,PUT,POST');
        res.header('Access-Control-Allow-Headers', 'Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept');
        res.send(200);
    }
  );
};

You can consolidate the res.header() code into a single function if you want.

Also as stated above, be careful of using res.header('Access-Control-Allow-Origin', "*") this means anyone can access your site!

If you want to remove the [ or the ], use the expression: "\\[|\\]".

The two backslashes escape the square bracket and the pipe is an "or".

Rising to @Ankan-Zerob's challenge, this is my estimate of the maximum length which can be stored in each text type measured in words:

      Type |         Bytes | English words | Multi-byte words
-----------+---------------+---------------+-----------------
  TINYTEXT |           255 |           ±44 |              ±23
      TEXT |        65,535 |       ±11,000 |           ±5,900
MEDIUMTEXT |    16,777,215 |    ±2,800,000 |       ±1,500,000
  LONGTEXT | 4,294,967,295 |  ±740,000,000 |     ±380,000,000

In English, 4.8 letters per word is probably a good average (eg norvig.com/mayzner.html), though word lengths will vary according to domain (e.g. spoken language vs. academic papers), so there's no point being too precise. English is mostly single-byte ASCII characters, with very occasional multi-byte characters, so close to one-byte-per-letter. An extra character has to be allowed for inter-word spaces, so I've rounded down from 5.8 bytes per word. Languages with lots of accents such as say Polish would store slightly fewer words, as would e.g. German with longer words.

Languages requiring multi-byte characters such as Greek, Arabic, Hebrew, Hindi, Thai, etc, etc typically require two bytes per character in UTF-8. Guessing wildly at 5 letters per word, I've rounded down from 11 bytes per word.

CJK scripts (Hanzi, Kanji, Hiragana, Katakana, etc) I know nothing of; I believe characters mostly require 3 bytes in UTF-8, and (with massive simplification) they might be considered to use around 2 characters per word, so they would be somewhere between the other two. (CJK scripts are likely to require less storage using UTF-16, depending).

This is of course ignoring storage overheads etc.

In Swift 4.1 and Xcode 9.4.1

I have two apps 1)PageViewControllerExample and 2)DelegateExample. Now i want to open DelegateExample app with PageViewControllerExample app. When i click open button in PageViewControllerExample, DelegateExample app will be opened.

For this we need to make some changes in .plist files for both the apps.

Step 1

In DelegateExample app open .plist file and add URL Types and URL Schemes. Here we need to add our required name like "myapp".

Step 2

In PageViewControllerExample app open .plist file and add this code

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>myapp</string>
</array>

Now we can open DelegateExample app when we click button in PageViewControllerExample.

//In PageViewControllerExample create IBAction
@IBAction func openapp(_ sender: UIButton) {

    let customURL = URL(string: "myapp://")
    if UIApplication.shared.canOpenURL(customURL!) {

        //let systemVersion = UIDevice.current.systemVersion//Get OS version
        //if Double(systemVersion)! >= 10.0 {//10 or above versions
            //print(systemVersion)
            //UIApplication.shared.open(customURL!, options: [:], completionHandler: nil)
        //} else {
            //UIApplication.shared.openURL(customURL!)
        //}

        //OR

        if #available(iOS 10.0, *) {
            UIApplication.shared.open(customURL!, options: [:], completionHandler: nil)
        } else {
            UIApplication.shared.openURL(customURL!)
        }
    } else {
         //Print alert here
    }
}

I have Mojave 10.14.6 and the only thing that did work for me was:

• setting JAVA_HOME to the following:

export JAVA_HOME=/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

• source .bash_profile (or wherever you keep your vars, in my case .zshrc)

Hope it helps! You can now type java --version and it should work

Trying not to sound zany, but can't help myself.

Your question should be what is the difference between mutex and semaphores ? And to be more precise question should be, 'what is the relationship between mutex and semaphores ?'

(I would have added that question but I'm hundred % sure some overzealous moderator would close it as duplicate without understanding difference between difference and relationship.)

In object terminology we can observe that :

observation.1 Semaphore contains mutex

observation.2 Mutex is not semaphore and semaphore is not mutex.

There are some semaphores that will act as if they are mutex, called binary semaphores, but they are freaking NOT mutex.

There is a special ingredient called Signalling (posix uses condition_variable for that name), required to make a Semaphore out of mutex. Think of it as a notification-source. If two or more threads are subscribed to same notification-source, then it is possible to send them message to either ONE or to ALL, to wakeup.

There could be one or more counters associated with semaphores, which are guarded by mutex. The simple most scenario for semaphore, there is a single counter which can be either 0 or 1.

This is where confusion pours in like monsoon rain.

A semaphore with a counter that can be 0 or 1 is NOT mutex.

Mutex has two states (0,1) and one ownership(task). Semaphore has a mutex, some counters and a condition variable.

Now, use your imagination, and every combination of usage of counter and when to signal can make one kind-of-Semaphore.

1. Single counter with value 0 or 1 and signaling when value goes to 1 AND then unlocks one of the guy waiting on the signal == Binary semaphore

2. Single counter with value 0 to N and signaling when value goes to less than N, and locks/waits when values is N == Counting semaphore

3. Single counter with value 0 to N and signaling when value goes to N, and locks/waits when values is less than N == Barrier semaphore (well if they dont call it, then they should.)

Now to your question, when to use what. (OR rather correct question version.3 when to use mutex and when to use binary-semaphore, since there is no comparison to non-binary-semaphore.) Use mutex when 1. you want a customized behavior, that is not provided by binary semaphore, such are spin-lock or fast-lock or recursive-locks. You can usually customize mutexes with attributes, but customizing semaphore is nothing but writing new semaphore. 2. you want lightweight OR faster primitive

Use semaphores, when what you want is exactly provided by it.

If you dont understand what is being provided by your implementation of binary-semaphore, then IMHO, use mutex.

And lastly read a book rather than relying just on SO.

Here's the version I ended up writing that replaces all instances of the target string in a given string. Works on any string type.

template <typename T, typename U>
T &replace (
          T &str, 
    const U &from, 
    const U &to)
{
    size_t pos;
    size_t offset = 0;
    const size_t increment = to.size();

    while ((pos = str.find(from, offset)) != T::npos)
    {
        str.replace(pos, from.size(), to);
        offset = pos + increment;
    }

    return str;
}

Example:

auto foo = "this is a test"s;
replace(foo, "is"s, "wis"s);
cout << foo;

Output:

thwis wis a test

Note that even if the search string appears in the replacement string, this works correctly.

._variable is semiprivate and meant just for convention

.__variable is often incorrectly considered superprivate, while it's actual meaning is just to namemangle to prevent accidental access[1]

.__variable__ is typically reserved for builtin methods or variables

You can still access .__mangled variables if you desperately want to. The double underscores just namemangles, or renames, the variable to something like instance._className__mangled

Example:

class Test(object):
    def __init__(self):
        self.__a = 'a'
        self._b = 'b'

>>> t = Test()
>>> t._b
'b'

t._b is accessible because it is only hidden by convention

>>> t.__a
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'Test' object has no attribute '__a'

t.__a isn't found because it no longer exists due to namemangling

>>> t._Test__a
'a'

By accessing instance._className__variable instead of just the double underscore name, you can access the hidden value

Changing the ng-src value is actually very simple. Like this:

<html ng-app>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.6/angular.min.js"></script>
</head>
<body>
<img ng-src="{{img_url}}">
<button ng-click="img_url = 'https://farm4.staticflickr.com/3261/2801924702_ffbdeda927_d.jpg'">Click</button>
</body>
</html>

Here is a jsFiddle of a working example: http://jsfiddle.net/Hx7B9/2/

One technique I think is a little easier and that hasn't been mentioned before here:

var asdf = new [] { 
    (Age: 1, Name: "cow"), 
    (Age: 2, Name: "bird")
}.ToList();

I think that's a little cleaner than:

var asdf = new List<Tuple<int, string>> { 
    (Age: 1, Name: "cow"), 
    (Age: 2, Name: "bird")
};

You cannot achieve the desired solution with CSS z-index either, as z-index is only relative to the parent element. So if you have parents A and B with respective children a and b, b's z-index is only relative to other children of B and a's z-index is only relative to other children of A.

The z-index of A and B are relative to each other if they share the same parent element, but all of the children of one will share the same relative z-index at this level.

I agree with erickson's answer, with one caveat: for password authentication purposes, bcrypt is far better than a single iteration of SHA-512 - simply because it is far slower. If you don't get why slowness is an advantage in this particular game, read the article you linked to again (scroll down to "Speed is exactly what you don’t want in a password hash function.").

You can of course build a secure password hashing algorithm around SHA-512 by iterating it thousands of times, just like the way PHK's MD5 algorithm works. Ulrich Drepper did exactly this, for glibc's crypt(). There's no particular reason to do this, though, if you already have a tested bcrypt implementation available.

When the jQuery click event calls your event handler, it sets "this" to the object that was clicked on. To turn it into a jQuery object, just pass it to the "$" function: $(this). So, to get, for example, the next sibling element, you would do this inside the click handler:

var nextSibling = $(this).next();

Edit: After reading Kevin's comment, I realized I might be mistaken about what you want. If you want to do what he asked, i.e. select the corresponding link in the other div, you could use $(this).index() to get the clicked link's position. Then you would select the link in the other div by its position, for example with the "eq" method.

var $clicked = $(this);
var linkIndex = $clicked.index();
$clicked.parent().next().children().eq(linkIndex);

If you want to be able to go both ways, you will need some way of determining which div you are in so you know if you need "next()" or "prev()" after "parent()"

Instead of using pull-right class, it is better to use text-right class in the column, because pull-right creates problems sometimes while resizing the page.

No to compare anything, you can simply check that by this...,.

if(document.getElementById("url")){ alert('exit');}
if($("#url")){alert('exist');}

you can also use the html() function as well like

if($("#url).html()){alert('exist');}

Something like this for $.ajax (HTML5 only though):

$.ajax({
    xhr: function() {
        var xhr = new window.XMLHttpRequest();
        xhr.upload.addEventListener("progress", function(evt) {
            if (evt.lengthComputable) {
                var percentComplete = evt.loaded / evt.total;
                //Do something with upload progress here
            }
       }, false);

       xhr.addEventListener("progress", function(evt) {
           if (evt.lengthComputable) {
               var percentComplete = evt.loaded / evt.total;
               //Do something with download progress
           }
       }, false);

       return xhr;
    },
    type: 'POST',
    url: "/",
    data: {},
    success: function(data){
        //Do something on success
    }
});

Explanation of command that i am going to write:-

. means any character, digit can come in place of .

* means zero or more occurrences of thing written just previous to it.

| means 'or'.

So,

james.*jack

would search james , then any number of character until jack comes.

Since you want either jack.*james or james.*jack

Hence Command:

jack.*james|james.*jack

calling bean action from a will be a good idea,keep attribute autoRun="true" example below

<p:remoteCommand autoRun="true" name="myRemoteCommand" action="#{bean.action}" partialSubmit="true" update=":form" />

One more thing. In my experience this error occurred because there was another error previous to the Function is not defined - uncaught referenceerror.

So, look through the console to see if a previous error exists and if so, correct any that exist. You might be lucky in that they were the problem.

I came up with a rock-solid solution for these issues that conforms with the 'Android Way' of things. I have all my long-running operations using the IntentService pattern.

That is, my activities broadcast intents, the IntentService does the work, saves the data in the DB and then broadcasts sticky intents. The sticky part is important, such that even if the Activity was paused during during the time after the user initiated the work and misses the real time broadcast from the IntentService we can still respond and pick up the data from the calling Activity. ProgressDialogs can work with this pattern quite nicely with onSaveInstanceState().

Basically, you need to save a flag that you have a progress dialog running in the saved instance bundle. Do not save the progress dialog object because this will leak the entire Activity. To have a persistent handle to the progress dialog, I store it as a weak reference in the application object. On orientation change or anything else that causes the Activity to pause (phone call, user hits home etc.) and then resume, I dismiss the old dialog and recreate a new dialog in the newly created Activity.

For indefinite progress dialogs this is easy. For progress bar style, you have to put the last known progress in the bundle and whatever information you're using locally in the activity to keep track of the progress. On restoring the progress, you'll use this information to re-spawn the progress bar in the same state as before and then update based on the current state of things.

So to summarize, putting long-running tasks into an IntentService coupled with judicious use of onSaveInstanceState() allows you to efficiently keep track of dialogs and restore then across the Activity life-cycle events. Relevant bits of Activity code are below. You'll also need logic in your BroadcastReceiver to handle Sticky intents appropriately, but that is beyond the scope of this.

public void doSignIn(View view) {
    waiting=true;
    AppClass app=(AppClass) getApplication();
    String logingon=getString(R.string.signon);
    app.Dialog=new WeakReference<ProgressDialog>(ProgressDialog.show(AddAccount.this, "", logingon, true));
    ...
}

@Override
protected void onSaveInstanceState(Bundle saveState) {
    super.onSaveInstanceState(saveState);
    saveState.putBoolean("waiting",waiting);

To remove everything before a certain character, use a regular expression:

re.sub(r'^[^a]*', '')

to remove everything up to the first 'a'. [^a] can be replaced with any character class you like, such as word characters.

To use the hex encoding in Python 3, use

>>> import codecs
>>> codecs.encode(b"c", "hex")
b'63'

In legacy Python, there are several other ways of doing this:

>>> hex(ord("c"))
'0x63'
>>> format(ord("c"), "x")
'63'
>>> "c".encode("hex")
'63'

Note : Only if you are not using angular modules

For some reason this is not in the docs but I had to import the custom pipe in the component

import {UsersPipe} from './users-filter.pipe'

@Component({

})

If you are planning to use JSONP you can use getJSON which made for that. jQuery has helper methods for JSONP.

$.getJSON( 'http://someotherdomain.com/service.svc&callback=?', function( result ) {
       console.log(result);
});

In case if you want to implement your own Array.Copy method.

Static method which is of generic type.

 static void MyCopy<T>(T[] sourceArray, long sourceIndex, T[] destinationArray, long destinationIndex, long copyNoOfElements)
 {
  long totaltraversal = sourceIndex + copyNoOfElements;
  long sourceArrayLength = sourceArray.Length;

  //to check all array's length and its indices properties before copying
  CheckBoundaries(sourceArray, sourceIndex, destinationArray, copyNoOfElements, sourceArrayLength);
   for (long i = sourceIndex; i < totaltraversal; i++)
     {
      destinationArray[destinationIndex++] = sourceArray[i]; 
     } 
  }

Boundary method implementation.

private static void CheckBoundaries<T>(T[] sourceArray, long sourceIndex, T[] destinationArray, long copyNoOfElements, long sourceArrayLength)
        {
            if (sourceIndex >= sourceArray.Length)
            {
                throw new IndexOutOfRangeException();
            }
            if (copyNoOfElements > sourceArrayLength)
            {
                throw new IndexOutOfRangeException();
            }
            if (destinationArray.Length < copyNoOfElements)
            {
                throw new IndexOutOfRangeException();
            }
        }

To have a cron executed on Sunday you can use either of these:

5 8 * * 0
5 8 * * 7
5 8 * * Sun

Where 5 8 stands for the time of the day when this will happen: 8:05.

In general, if you want to execute something on Sunday, just make sure the 5th column contains either of 0, 7 or Sun. You had 6, so it was running on Saturday.

The format for cronjobs is:

 +---------------- minute (0 - 59)
 |  +------------- hour (0 - 23)
 |  |  +---------- day of month (1 - 31)
 |  |  |  +------- month (1 - 12)
 |  |  |  |  +---- day of week (0 - 6) (Sunday=0 or 7)
 |  |  |  |  |
 *  *  *  *  *  command to be executed

You can always use crontab.guru as a editor to check your cron expressions.

Just select the code and

• on Windows do Ctrl + Alt + L

• on Linux do Ctrl + Super + Alt + L

• on Mac do CMD + Alt + L

This solution from junaidp

You could do something like this if you wanted

package main

import "fmt"

type Pair struct {
    a, b interface{}
}

func main() {
    p1 := Pair{"finished", 42}
    p2 := Pair{6.1, "hello"}
    fmt.Println("p1=", p1, "p2=", p2)
    fmt.Println("p1.b", p1.b)
    // But to use the values you'll need a type assertion
    s := p1.a.(string) + " now"
    fmt.Println("p1.a", s)
}

However I think what you have already is perfectly idiomatic and the struct describes your data perfectly which is a big advantage over using plain tuples.

HttpClient lives in the System.Net.Http namespace.

You'll need to add:

using System.Net.Http;

And make sure you are referencing System.Net.Http.dll in .NET 4.5.

The code posted doesn't appear to do anything with webClient. Is there something wrong with the code that is actually compiling using HttpWebRequest?

Update

To open the Add Reference dialog right-click on your project in Solution Explorer and select Add Reference.... It should look something like:

I did this by installing Cygwin64 from this link https://www.cygwin.com/ Then - View Full, Search gcc and scroll down to find pkg-config. Click on icon to select latest version. This worked for me well.

You can resolve the issue by forcing the collation used in a query to be a particular collation, e.g. SQL_Latin1_General_CP1_CI_AS or DATABASE_DEFAULT. For example:

SELECT MyColumn
FROM FirstTable a
INNER JOIN SecondTable b
ON a.MyID COLLATE SQL_Latin1_General_CP1_CI_AS = 
b.YourID COLLATE SQL_Latin1_General_CP1_CI_AS

In the above query, a.MyID and b.YourID would be columns with a text-based data type. Using COLLATE will force the query to ignore the default collation on the database and instead use the provided collation, in this case SQL_Latin1_General_CP1_CI_AS.

Basically what's going on here is that each database has its own collation which "provides sorting rules, case, and accent sensitivity properties for your data" (from http://technet.microsoft.com/en-us/library/ms143726.aspx) and applies to columns with textual data types, e.g. VARCHAR, CHAR, NVARCHAR, etc. When two databases have differing collations, you cannot compare text columns with an operator like equals (=) without addressing the conflict between the two disparate collations.

A standard-compliant, easy-to-remember set of html quotes, starting with the right single-quote which is normally used as an apostrophe:

• right single-quote — ’ — ’
• left single-quote — ‘ — ‘
• right double-quote — ” — ”
• left double-quote — “ — “

We can set layout gravity on any view like below way-

myView = findViewById(R.id.myView);
myView.setGravity(Gravity.CENTER_VERTICAL|Gravity.RIGHT);
 or
myView.setGravity(Gravity.BOTTOM);

This is equilent to below xml code

<...

You can create static class inside your controller like this :

    @Controller
    public class HomeController {
        @Autowired
        private LoginServiceConfiguration loginServiceConfiguration;

        @RequestMapping(value = "/view", method = RequestMethod.GET)
        public ModelAndView display(HttpServletRequest req) {
            ModelAndView mav = new ModelAndView("home");
            mav.addObject("loginAction", loginServiceConfiguration.loginAction());
            return mav;
        }


        @Configuration
        public static class LoginServiceConfiguration {

            @Bean(name = "loginActionBean")
            @Scope("prototype")
            public LoginAction loginAction() {
                return new LoginAction();
            }
        }
}

I generally use array split because it's easier simple syntax and scales better with more than 2 partitions.

import numpy as np
partitions = 2
dfs = np.array_split(df, partitions)

np.split(df, [100,200,300], axis=0] wants explicit index numbers which may or may not be desirable.

There is no way to "discard" the time component.

DateTime.Today is the same as:

DateTime d = DateTime.Now.Date;

If you only want to display only the date portion, simply do that - use ToString with the format string you need.

For example, using the standard format string "D" (long date format specifier):

d.ToString("D");

If you define a color in your XML and want to use it to change background color or something this API is the one your are looking for:

 ((TextView) view).setBackgroundResource(R.drawable.your_color_here);

In my sample I used it for TestView

The __del__ method (note spelling!) is called when your object is finally destroyed. Technically speaking (in cPython) that is when there are no more references to your object, ie when it goes out of scope.

If you want to delete your object and thus call the __del__ method use

del obj1

which will delete the object (provided there weren't any other references to it).

I suggest you write a small class like this

class T:
    def __del__(self):
        print "deleted"

And investigate in the python interpreter, eg

>>> a = T()
>>> del a
deleted
>>> a = T()
>>> b = a
>>> del b
>>> del a
deleted
>>> def fn():
...     a = T()
...     print "exiting fn"
...
>>> fn()
exiting fn
deleted
>>>   

Note that jython and ironpython have different rules as to exactly when the object is deleted and __del__ is called. It isn't considered good practice to use __del__ though because of this and the fact that the object and its environment may be in an unknown state when it is called. It isn't absolutely guaranteed __del__ will be called either - the interpreter can exit in various ways without deleteting all objects.

src/main/resources is the "standard placement" for this.

Update: The above answers the question, but its not the best solution. Check out the other answers and the comments on this ... you would probably not shipping your own logging properties with the jar but instead leave it to the client (for example app-server, stage environment, etc) to configure the desired logging. Thus, putting it in src/test/resources is my preferred solution.

Note: Speaking of leaving the concrete log config to the client/user, you should consider replacing log4j with slf4j in your app.

Look at my project CalcBinding, which provides to you writing complex expressions in Path property value, including static properties, source properties, Math and other. So, you can write this:

<TextBox Text="{c:Binding local:VersionManager.FilterString}"/>

Goodluck!

This could be caused by a few things (most likely to least likely):

1. The server's SSL certificate is untrusted by the client. Easiest check is to point a browser at the URL and see if you get an SSL lock icon. If you get a broken lock, icon, click on it to see what the issue is:

   1. Expired dates - get a new SSL certificate
   2. Name does not match - make sure that your URL uses the same server name as the certificate.
   3. Not signed by a trusted authority - buy a certificate from an authority such as Verisign, or add the certificate to the client's trusted certificate store.
   4. In test environments you could update your certificate validator to skip access checks. Don't do this in production.

2. Server is requiring Client SSL certificate - in this case you would have to update your code to sign the request with a client certificate.

It is not too surprising: the execution plan for the tiny insert is computed once, and then reused 1000 times. Parsing and preparing the plan is quick, because it has only four values to del with. A 1000-row plan, on the other hand, needs to deal with 4000 values (or 4000 parameters if you parameterized your C# tests). This could easily eat up the time savings you gain by eliminating 999 roundtrips to SQL Server, especially if your network is not overly slow.

To remove all doted outline, including those in bootstrap themes.

a, a:active, a:focus, 
button, button:focus, button:active, 
.btn, .btn:focus, .btn:active:focus, .btn.active:focus, .btn.focus, .btn.focus:active, .btn.active.focus {
    outline: none;
    outline: 0;
}

input::-moz-focus-inner {
    border: 0;
}

Note: You should add link href for bootstrap css before the main css, so bootstrap doesn't override your style.

You could use the object data type:

>>> import numpy
>>> s = numpy.array(['a', 'b', 'dude'], dtype='object')
>>> s[0] += 'bcdef'
>>> s
array([abcdef, b, dude], dtype=object)

I think the answer is pretty simple (unless I'm missing something?)

SELECT    
CASE
    WHEN col1 > col2 THEN SUM(col3*col4)
    ELSE 0
END AS some_product
FROM some_table
GROUP BY
CASE
    WHEN col1 > col2 THEN SUM(col3*col4)
    ELSE 0
END

You can put the CASE STATEMENT in the GROUP BY verbatim (minus the alias column name)

As of today (27, February 2020) Oracle announced that it has published all JDBC client libraries from version 11.2.0.4 (e.g. ojdbc6) to 19.3.0 (e.g. ojdbc10) on Maven Central under the group id com.oracle.database:

Example:

<dependency>
  <groupId>com.oracle.database.jdbc</groupId>
  <artifactId>ojdbc10</artifactId>
  <version>19.3.0.0</version>
</dependency>

As per this answer over here: str='foo%20%5B12%5D' encodes foo [12]:

%20 is space
%5B is '['
and %5D is ']'

This is called percent encoding and is used in encoding special characters in the url parameter values.

EDIT By the way as I was reading https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/encodeURI#Description, it just occurred to me why so many people make the same search. See the note on the bottom of the page:

Also note that if one wishes to follow the more recent RFC3986 for URL's, making square brackets reserved (for IPv6) and thus not encoded when forming something which could be part of a URL (such as a host), the following may help.

function fixedEncodeURI (str) {
    return encodeURI(str).replace(/%5B/g, '[').replace(/%5D/g, ']');
}

Hopefully this will help people sort out their problems when they stumble upon this question.

Use the SQLCMD utility.

http://technet.microsoft.com/en-us/library/ms162773.aspx

There is a connect statement that allows you to swing from database server A to server B in the same batch.

:Connect server_name[\instance_name] [-l timeout] [-U user_name [-P password]] Connects to an instance of SQL Server. Also closes the current connection.

On the other hand, if you are familiar with PowerShell, you can programmatic do the same.

Assuming you're getting norm from scipy.stats, you probably just need to sort your list:

import numpy as np
import scipy.stats as stats
import matplotlib.pyplot as plt

h = [186, 176, 158, 180, 186, 168, 168, 164, 178, 170, 189, 195, 172,
     187, 180, 186, 185, 168, 179, 178, 183, 179, 170, 175, 186, 159,
     161, 178, 175, 185, 175, 162, 173, 172, 177, 175, 172, 177, 180]
h.sort()
hmean = np.mean(h)
hstd = np.std(h)
pdf = stats.norm.pdf(h, hmean, hstd)
plt.plot(h, pdf) # including h here is crucial

And so I get:

In Code behind you can achieve it only by doing this.

 private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            txtIndex.Focusable = true;
            txtIndex.Focus();

Note: It wont work before window is loaded

No, goto is not used in Java, despite being a reserved word. The same is true for const. Both of these are used in C++, which is probably the reason why they're reserved; the intention was probably to avoid confusing C++ programmers migrating to Java, and perhaps also to keep the option of using them in later revisions of Java.

found this and it worked for me.

strSQL = "SELECT * FROM DataTable" 

'Where DataTable is the Named range

How can I run SQL statements on a named range within an excel sheet?

Just make sure that your HTML file is encoded with UTF-8 and that your web server sends a HTTP header with that charset, then you just can write that character directly into your HTMl file.

http://www.w3.org/International/O-HTTP-charset

If you can't use UTF-8 for some reason, you can look up the codes in a unicode list such as http://en.wikipedia.org/wiki/List_of_Unicode_characters and use ꯍ where ABCD is the hexcode from that list (U+ABCD).

I know this is an old question, but I wanted to make sure a couple of other options are noted.

Since you can't store a TimeSpan greater than 24 hours in a time sql datatype field; a couple of other options might be.

1. Use a varchar(xx) to store the ToString of the TimeSpan. The benefit of this is the precision doesn't have to be baked into the datatype or the calculation, (seconds vs milliseconds vs days vs fortnights) All you need to to is use TimeSpan.Parse/TryParse. This is what I would do.

2. Use a second date, datetime or datetimeoffset, that stores the result of first date + timespan. Reading from the db is a matter of TimeSpan x = SecondDate - FirstDate. Using this option will protect you for other non .NET data access libraries access the same data but not understanding TimeSpans; in case you have such an environment.

<servlet-mapping>
  <servlet-name>dispatcher</servlet-name>
  <url-pattern>/*</url-pattern>

  <url-pattern>/</url-pattern>
</servlet-mapping>

<img id="uxcMyImageId" src"myImage" width="100" height="100" />

specifying width and height in the image tag is a good practice..this way when the page loads there is space allocated for the image and the layout does not suffer any jerks even if the image takes a long time to load.

You can also use .apply:

df.apply(lambda row: row[df['B'].isin(['one','three'])])

It actually works row-wise (i.e., applies the function to each row).

The output is

   A      B  C   D
0  foo    one  0   0
1  bar    one  1   2
3  bar  three  3   6
6  foo    one  6  12
7  foo  three  7  14

The results is the same as using as mentioned by @unutbu

df[[df['B'].isin(['one','three'])]]

For Python 3.4+ on Centos 6/7,Fedora, just install the trusted CA this way :

1. Copy the CA.crt to /etc/pki/ca-trust/source/anchors/
2. update-ca-trust force-enable
3. update-ca-trust extract

In Gradle using Android plugin:

gradle.projectsEvaluated {
    tasks.withType(Test) { task ->
        task.afterTest { desc, result ->
            println "Executing test ${desc.name} [${desc.className}] with result: ${result.resultType}"
        }
    }
}

Then the output will be:

Executing test testConversionMinutes [org.example.app.test.DurationTest] with result: SUCCESS

var rotator = function(){
  widget.Rotator.rotate();
  setTimeout(rotator,5000);
};
rotator();

Or:

setInterval(
  function(){ widget.Rotator.rotate() },
  5000
);

Or:

setInterval(
  widget.Rotator.rotate.bind(widget.Rotator),
  5000
);

You might try passing actual types instead of strings.

import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4'] 
dtypes = [datetime, datetime, str, float] 
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)

But it's going to be really hard to diagnose this without any of your data to tinker with.

And really, you probably want pandas to parse the the dates into TimeStamps, so that might be:

pd.read_csv(file, sep='\t', header=None, names=headers, parse_dates=True)

I think it's just because you have forgot HTTP METHOD. The default HTTP method of request is GET.

You should add method: 'POST' and your code will work if your backend receive the post method.

var req = require('request');

req.post({
   url: 'someUrl',
   form: { username: 'user', password: '', opaque: 'someValue', logintype: '1'},
   headers: { 
      'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.110 Safari/537.36',
      'Content-Type' : 'application/x-www-form-urlencoded' 
   },
   method: 'POST'
  },

  function (e, r, body) {
      console.log(body);
  });

GUI-driven approach: Open the docker desktop tool (that usually comes with Docker):

1. under "Containers / Apps" stop all running instances of that image
2. under "Images" remove the build image (hover over the box name to get a context menu), eventually also the underlying base image

This may sound dumb, but it may be a fresh, or damaged install, so is the JDK installed? If not, go to the download site and download the latest version of Java JRE. Like I said, this may sound dumb, but it solved my problem.

Here's yet another answer offering commentary on how Muis, Abdullah Al-Ageel and Flip's answer are all mathematically the same thing except written differently.

Sure, we have José Manuel Ramos's analysis explaining how rounding errors affect each slightly differently, but that's implementation dependent and would change based on how each answer were applied to code.

There is however a rather big difference

It's in Muis's N, Flip's k, and Abdullah Al-Ageel's n. Abdullah Al-Ageel doesn't quite explain what n should be, but N and k differ in that N is "the number of samples where you want to average over" while k is the count of values sampled. (Although I have doubts to whether calling N the number of samples is accurate.)

And here we come to the answer below. It's essentially the same old exponential weighted moving average as the others, so if you were looking for an alternative, stop right here.

Exponential weighted moving average

Initially:

average = 0
counter = 0

For each value:

counter += 1
average = average + (value - average) / min(counter, FACTOR)

The difference is the min(counter, FACTOR) part. This is the same as saying min(Flip's k, Muis's N).

FACTOR is a constant that affects how quickly the average "catches up" to the latest trend. Smaller the number the faster. (At 1 it's no longer an average and just becomes the latest value.)

This answer requires the running counter counter. If problematic, the min(counter, FACTOR) can be replaced with just FACTOR, turning it into Muis's answer. The problem with doing this is the moving average is affected by whatever average is initiallized to. If it was initialized to 0, that zero can take a long time to work its way out of the average.

How it ends up looking

This extension that @Rob suggested works for Swift 3.0.1

I wasn't able to compile the version he included in his post with Xcode 8.1 (8B62)

extension Dictionary {

    /// Build string representation of HTTP parameter dictionary of keys and objects
    ///
    /// :returns: String representation in the form of key1=value1&key2=value2 where the keys and values are percent escaped

    func stringFromHttpParameters() -> String {

        var parametersString = ""
        for (key, value) in self {
            if let key = key as? String,
               let value = value as? String {
                parametersString = parametersString + key + "=" + value + "&"
            }
        }
        parametersString = parametersString.substring(to: parametersString.index(before: parametersString.endIndex))
        return parametersString.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)!
    }

}

In Addition to the above answers, there probably should be noted that there is a legacy way to implement the initialization. There is an interface called Initializable from the fxml library.

import javafx.fxml.Initializable;

class MyController implements Initializable {
    @FXML private TableView<MyModel> tableView;

    @Override
    public void initialize(URL location, ResourceBundle resources) {
        tableView.getItems().addAll(getDataFromSource());
    }
}

Parameters:

location - The location used to resolve relative paths for the root object, or null if the location is not known.
resources - The resources used to localize the root object, or null if the root object was not localized. 

And the note of the docs why the simple way of using @FXML public void initialize() works:

NOTE This interface has been superseded by automatic injection of location and resources properties into the controller. FXMLLoader will now automatically call any suitably annotated no-arg initialize() method defined by the controller. It is recommended that the injection approach be used whenever possible.

$mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for Gmail
$mail->Host = "smtp.gmail.com";
$mail->Port = 465; // or 587
$mail->IsHTML(true);
$mail->Username = "[email protected]";
$mail->Password = "password";
$mail->SetFrom("[email protected]");
$mail->Subject = "Test";
$mail->Body = "hello";
$mail->AddAddress("[email protected]");

 if(!$mail->Send()) {
    echo "Mailer Error: " . $mail->ErrorInfo;
 } else {
    echo "Message has been sent";
 }

This code above has been tested and worked for me.

It could be that you needed $mail->SMTPSecure = 'ssl';

Also make sure you don't have two step verification switched on for that account as that can cause problems also.

UPDATED

You could try changing $mail->SMTP to:

$mail->SMTPSecure = 'tls';

It's worth noting that some SMTP servers block connections. Some SMTP servers don't support SSL (or TLS) connections.

You can use slice notation with steps:

>>> x = "abcdefghijklm"
>>> x[0::2] #0. 2. 4...
'acegikm'
>>> x[1::2] #1. 3. 5 ..
'bdfhjl'
>>> [i+j for i,j in zip(x[::2], x[1::2])] # zip makes (0,1),(2,3) ...
['ab', 'cd', 'ef', 'gh', 'ij', 'kl']

Same logic applies for lists too. String lenght doesn't matter, because you're simply adding two strings together.

Yeah, resolved the exception by adding commons-collections4-4.1 jar file to the CLASSPATH user varible of system. Downloaded from https://mvnrepository.com/artifact/org.apache.commons/commons-collections4/4.1

Here is one way to do it from an article titled "Format query output into an HTML table - the easy way [archive]". You would need to substitute the details of your own query for the ones in this example, which gets a list of tables and a row count.

declare @body varchar(max)

set @body = cast( (
select td = dbtable + '</td><td>' + cast( entities as varchar(30) ) + '</td><td>' + cast( rows as varchar(30) )
from (
      select dbtable  = object_name( object_id ),
             entities = count( distinct name ),
             rows     = count( * )
      from sys.columns
      group by object_name( object_id )
      ) as d
for xml path( 'tr' ), type ) as varchar(max) )

set @body = '<table cellpadding="2" cellspacing="2" border="1">'
          + '<tr><th>Database Table</th><th>Entity Count</th><th>Total Rows</th></tr>'
          + replace( replace( @body, '&lt;', '<' ), '&gt;', '>' )
          + '</table>'

print @body

Once you have @body, you can then use whatever email mechanism you want.

You can also use ls -w1

This allows to set number of columns. From manpage of ls:

   -w, --width=COLS
          set output width to COLS.  0 means no limit

If you can use apache.commons.lang in your project, the easiest way would be just to use the method provided there:

public static boolean containsWhitespace(CharSequence seq)

Check whether the given CharSequence contains any whitespace characters.

Parameters:

seq - the CharSequence to check (may be null) 

Returns:

true if the CharSequence is not empty and contains at least 1 whitespace character

It handles empty and null parameters and provides the functionality at a central place.

"Chrome violations" don't represent errors in either Chrome or your own web app. They are instead warnings to help you improve your app. In this case, Long running JavaScript and took 83ms of runtime are alerting you there's probably an opportunity to speed up your script.

("Violation" is not the best terminology; it's used here to imply the script "violates" a pre-defined guideline, but "warning" or similar would be clearer. These messages first appeared in Chrome in early 2017 and should ideally have a "More info" prompt to elaborate on the meaning and give suggested actions to the developer. Hopefully those will be added in the future.)

class Graph<E> {
    private List<Vertex<E>> vertices;

    private static class Vertex<E> {
        E elem;
        List<Vertex<E>> neighbors;
    }
}

I'm thinking no. Bookmarks/favorites should be under the control of the user, imagine if any site you visited could insert itself into your bookmarks with just some javascript.

I was looking for the same thing and I just found this list

https://developers.facebook.com/docs/reference/api/errors/

A "BEFORE-INSERT"-trigger is the only way to realize same-table updates on an insert, and is only possible from MySQL 5.5+. However, the value of an auto-increment field is only available to an "AFTER-INSERT" trigger - it defaults to 0 in the BEFORE-case. Therefore the following example code which would set a previously-calculated surrogate key value based on the auto-increment value id will compile, but not actually work since NEW.id will always be 0:

create table products(id int not null auto_increment, surrogatekey varchar(10), description text);
create trigger trgProductSurrogatekey before insert on product
for each row set NEW.surrogatekey = 
  (select surrogatekey from surrogatekeys where id = NEW.id);

var element = $("#parentDiv .myClassNameOfInterest")

If you want to delete all files whose names match a particular form, a wildcard (glob pattern) is the most straightforward solution. Some examples:

$ rm -f abc.log.*             # Remove them all
$ rm -f abc.log.2012*         # Remove all logs from 2012
$ rm -f abc.log.2012-0[123]*  # Remove all files from the first quarter of 2012

Regular expressions are more powerful than wildcards; you can feed the output of grep to rm -f. For example, if some of the file names start with "abc.log" and some with "ABC.log", grep lets you do a case-insensitive match:

$ rm -f $(ls | grep -i '^abc\.log\.')

This will cause problems if any of the file names contain funny characters, including spaces. Be careful.

When I do this, I run the ls | grep ... command first and check that it produces the output I want -- especially if I'm using rm -f:

$ ls | grep -i '^abc\.log\.'
(check that the list is correct)
$ rm -f $(!!)

where !! expands to the previous command. Or I can type up-arrow or Ctrl-P and edit the previous line to add the rm -f command.

This assumes you're using the bash shell. Some other shells, particularly csh and tcsh and some older sh-derived shells, may not support the $(...) syntax. You can use the equivalent backtick syntax:

$ rm -f `ls | grep -i '^abc\.log\.'`

The $(...) syntax is easier to read, and if you're really ambitious it can be nested.

Finally, if the subset of files you want to delete can't be easily expressed with a regular expression, a trick I often use is to list the files to a temporary text file, then edit it:

$ ls > list
$ vi list   # Use your favorite text editor

I can then edit the list file manually, leaving only the files I want to remove, and then:

$ rm -f $(<list)

or

$ rm -f `cat list`

(Again, this assumes none of the file names contain funny characters, particularly spaces.)

Or, when editing the list file, I can add rm -f to the beginning of each line and then:

$ . ./list

or

$ source ./list

Editing the file is also an opportunity to add quotes where necessary, for example changing rm -f foo bar to rm -f 'foo bar' .

IF YOU ARE USING NGINX :

1. cd /etc/php/<PHP_VERSION>/fpm example => cd /etc/php/7.2/fpm

2. nano php.ini

   post_max_size = 1024M 
   upload_max_filesize = 1024M 
   max_execution_time = 3600 
   max_input_time = 3600 
   memory_limit = 1024M 
   

3. after saving php.ini file , restart fpm using :

   systemctl restart php<PHP_VERSION>-fpm
   

example => systemctl restart php7.2-fpm

It's a sort of dummy table with a single record used for selecting when you're not actually interested in the data, but instead want the results of some system function in a select statement:

e.g. select sysdate from dual;

See http://www.adp-gmbh.ch/ora/misc/dual.html

"16:23:01" doesn't match the pattern of "hh:mm:ss tt" - it doesn't have an am/pm designator, and 16 clearly isn't in a 12-hour clock. You're specifying that format in the parsing part, so you need to match the format of the existing data. You want:

DateTime dateTime = DateTime.ParseExact(time, "HH:mm:ss",
                                        CultureInfo.InvariantCulture);

(Note the invariant culture, not the current culture - assuming your input genuinely always uses colons.)

If you want to format it to hh:mm:ss tt, then you need to put that part in the ToString call:

lblClock.Text = date.ToString("hh:mm:ss tt", CultureInfo.CurrentCulture);

Or better yet (IMO) use "whatever the long time pattern is for the culture":

lblClock.Text = date.ToString("T", CultureInfo.CurrentCulture);

Also note that hh is unusual; typically you don't want to 0-left-pad the number for numbers less than 10.

(Also consider using my Noda Time API, which has a LocalTime type - a more appropriate match for just a "time of day".)

Remove the date() part

SELECT name, datum 
FROM tasks 
WHERE datum >= NOW()

and if you use a specific date, don't forget the quotes around it and use the proper format with :

SELECT name, datum 
FROM tasks 
WHERE datum >= '2014-05-18 15:00:00'

You simply need to enclose your SELECT statements in parentheses to indicate that they are subqueries:

SET cityLat = (SELECT cities.lat FROM cities WHERE cities.id = cityID);

Alternatively, you can use MySQL's SELECT ... INTO syntax. One advantage of this approach is that both cityLat and cityLng can be assigned from a single table-access:

SELECT lat, lng INTO cityLat, cityLng FROM cities WHERE id = cityID;

However, the entire procedure can be replaced with a single self-joined SELECT statement:

SELECT   b.*, HAVERSINE(a.lat, a.lng, b.lat, b.lng) AS dist
FROM     cities AS a, cities AS b
WHERE    a.id = cityID
ORDER BY dist
LIMIT    10;

I had the same issue.

During the 1st development I used a .csv file (comma as separator) that I've modified a bit before saving it. After saving the commas became semicolon.

On Windows it is dependent on the "Regional and Language Options" customize screen where you find a List separator. This is the char Windows applications expect to be the CSV separator.

When testing from a brand new file I encountered that issue.

I've removed the 'sep' argument in read_csv method before:

df1 = pd.read_csv('myfile.csv', sep=',');

after:

df1 = pd.read_csv('myfile.csv');

That way, the issue disappeared.

try this following snippet, its working fine.

private void button1_Click(object sender, EventArgs e)
{
     try
     {
             OpenFileDialog openfile1 = new OpenFileDialog();
             if (openfile1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
             {
                   this.textBox1.Text = openfile1.FileName;
             }
             {
                   string pathconn = "Provider = Microsoft.jet.OLEDB.4.0; Data source=" + textBox1.Text + ";Extended Properties=\"Excel 8.0;HDR= yes;\";";
                   OleDbConnection conn = new OleDbConnection(pathconn);
                   OleDbDataAdapter MyDataAdapter = new OleDbDataAdapter("Select * from [" + textBox2.Text + "$]", conn);
                   DataTable dt = new DataTable();
                   MyDataAdapter.Fill(dt);
                   dataGridView1.DataSource = dt;
             }
      }
      catch { }
}

For xCode 10, first you need to add the image in your assetsCatalogue and then type this:

let imageView = UIImageView(image: #imageLiteral(resourceName: "type the name of your image here..."))

For beginners, let imageView is the name of the UIImageView object we are about to create.

An example for embedding an image into a viewControler file would look like this:

import UIKit

class TutorialViewCotroller: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        let imageView = UIImageView(image: #imageLiteral(resourceName: "intoImage"))
        view.addSubview(imageView)
    }
}

Please notice that I did not use any extension for the image file name, as in my case it is a group of images.

Installation Tool Recommendations

1. Use pip to install Python packages from PyPI.
2. Use virtualenv, or pyvenv to isolate application specific dependencies from a shared Python installation.
3. Use pip wheel to create a cache of wheel distributions, for the purpose of > speeding up subsequent installations.
4. If you’re looking for management of fully integrated cross-platform software stacks, consider buildout (primarily focused on the web development community) or Hashdist, or conda (both primarily focused on the scientific community).

Packaging Tool Recommendations

1. Use setuptools to define projects and create Source Distributions.
2. Use the bdist_wheel setuptools extension available from the wheel project to create wheels. This is especially beneficial, if your project contains binary extensions.
3. Use twine for uploading distributions to PyPI.

This anwser has aged, and indeed there is a rescue plan for python packaging world called

wheels way

I qoute pythonwheels.com here:

What are wheels?

Wheels are the new standard of python distribution and are intended to replace eggs. Support is offered in pip >= 1.4 and setuptools >= 0.8.

Advantages of wheels

1. Faster installation for pure python and native C extension packages.
2. Avoids arbitrary code execution for installation. (Avoids setup.py)
3. Installation of a C extension does not require a compiler on Windows or OS X.
4. Allows better caching for testing and continuous integration.
5. Creates .pyc files as part of installation to ensure they match the python interpreter used.
6. More consistent installs across platforms and machines.

The full story of correct python packaging (and about wheels) is covered at packaging.python.org

conda way

For scientific computing (this is also recommended on packaging.python.org, see above) I would consider using CONDA packaging which can be seen as a 3rd party service build on top of PyPI and pip tools. It also works great on setting up your own version of binstar so I would imagine it can do the trick for sophisticated custom enterprise package management.

Conda can be installed into a user folder (no super user permisssions) and works like magic with

conda install

and powerful virtual env expansion.

eggs way

This option was related to python-distribute.org and is largerly outdated (as well as the site) so let me point you to one of the ready to use yet compact setup.py examples I like:

• A very practical example/implementation of mixing scripts and single python files into setup.py is giving here
• Even better one from hyperopt

This quote was taken from the guide on the state of setup.py and still applies:

• setup.py gone!
• distutils gone!
• distribute gone!
• pip and virtualenv here to stay!
• eggs ... gone!

I add one more point (from me)

• wheels!

I would recommend to get some understanding of packaging-ecosystem (from the guide pointed by gotgenes) before attempting mindless copy-pasting.

from distutils.core import setup

from setuptools import setup

pip install Distutils2

python -m distutils2.run install

PS

Packaging never was trivial (one learns this by trying to develop a new one), so I assume a lot of things have gone for reason. I just hope this time it will be is done correctly.

I've tried this 2 options (read/write), with plain objects, array of objects (150 objects), Map:

Option1:

FileOutputStream fos = context.openFileOutput(fileName, Context.MODE_PRIVATE);
ObjectOutputStream os = new ObjectOutputStream(fos);
os.writeObject(this);
os.close();

Option2:

SharedPreferences mPrefs=app.getSharedPreferences(app.getApplicationInfo().name, Context.MODE_PRIVATE);
SharedPreferences.Editor ed=mPrefs.edit();
Gson gson = new Gson(); 
ed.putString("myObjectKey", gson.toJson(objectToSave));
ed.commit();

Option 2 is twice quicker than option 1

The option 2 inconvenience is that you have to make specific code for read:

Gson gson = new Gson();
JsonParser parser=new JsonParser();
//object arr example
JsonArray arr=parser.parse(mPrefs.getString("myArrKey", null)).getAsJsonArray();
events=new Event[arr.size()];
int i=0;
for (JsonElement jsonElement : arr)
    events[i++]=gson.fromJson(jsonElement, Event.class);
//Object example
pagination=gson.fromJson(parser.parse(jsonPagination).getAsJsonObject(), Pagination.class);

all depend on the configuration. for me works

comboBox.SelectedIndex = -1;

my configuration

DropDownStyle: DropDownList

(text can't be changed for the user)

Try just --with-curl, without specifying a location, and see if it'll find it by itself.

I think this is what you're looking for:

Tk.attributes("-fullscreen", True)  # substitute `Tk` for whatever your `Tk()` object is called

You can use wm_attributes instead of attributes, too.

Then just bind the escape key and add this to the handler:

Tk.attributes("-fullscreen", False)

An answer to another question alluded to this (with wm_attributes). So, that's how I found out. But, no one just directly went out and said it was the answer for some reason. So, I figured it was worth posting.

Here's a working example (tested on Xubuntu 14.04) that uses F11 to toggle fullscreen on and off and where escape will turn it off only:

import sys
if sys.version_info[0] == 2:  # Just checking your Python version to import Tkinter properly.
    from Tkinter import *
else:
    from tkinter import *


class Fullscreen_Window:

    def __init__(self):
        self.tk = Tk()
        self.tk.attributes('-zoomed', True)  # This just maximizes it so we can see the window. It's nothing to do with fullscreen.
        self.frame = Frame(self.tk)
        self.frame.pack()
        self.state = False
        self.tk.bind("<F11>", self.toggle_fullscreen)
        self.tk.bind("<Escape>", self.end_fullscreen)

    def toggle_fullscreen(self, event=None):
        self.state = not self.state  # Just toggling the boolean
        self.tk.attributes("-fullscreen", self.state)
        return "break"

    def end_fullscreen(self, event=None):
        self.state = False
        self.tk.attributes("-fullscreen", False)
        return "break"

if __name__ == '__main__':
    w = Fullscreen_Window()
    w.tk.mainloop()

If you want to hide a menu, too, there are only two ways I've found to do that. One is to destroy it. The other is to make a blank menu to switch between.

self.tk.config(menu=self.blank_menu)  # self.blank_menu is a Menu object

Then switch it back to your menu when you want it to show up again.

self.tk.config(menu=self.menu)  # self.menu is your menu.

Two ways to get this done:

Collections.sort(myArray)

given elements inside myArray implements Comparable

Second

Collections.sort(myArray, new MyArrayElementComparator());

where MyArrayElementComparator is Comparator for elements inside myArray

Root cause: Corrupted user profile of user account used to start database

The main thread here seems to be a corrupted user account profile for the account that is used to start the DB engine. This is the account that was specified for the "SQL Server Database" engine during installation. In the setup event log, it's also indicated by the following entry:

SQLSVCACCOUNT:                 NT AUTHORITY\SYSTEM

According to the link provided by @royki:

The root cause of this issue, in most cases, is that the profile of the user being used for the service account (in my case it was local system) is corrupted.

This would explain why other respondents had success after changing to different accounts:

• bmjjr suggests changing to "NT AUTHORITY\NETWORK SERVICE"
• comments to @bmjjr indicate different accounts "I used NT AUTHORITY\LOCAL SERVICE. That helped too"
• @Julio Nobre had success with "NT Authority\System "

Fix: reset the corrupt user profile

To fix the user profile that's causing the error, follow the steps listed KB947215.

The main steps from KB947215 are summarized as follows:-

1. Open regedit
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

3. Navigate to the SID for the corrupted profile

   To find the SID, click on each SID GUID, review the value for the ProfileImagePath value, and see if it's the correct account. For system accounts, there's a different way to know the SID for the account that failed:

The main system account SIDs of interest are:

SID          Name               Also Known As
S-1-5-18     Local System       NT AUTHORITY\SYSTEM
S-1-5-19     LocalService       NT AUTHORITY\LOCAL SERVICE
S-1-5-20     NetworkService     NT AUTHORITY\NETWORK SERVICE

For information on additional SIDs, see Well-known security identifiers in Windows operating systems.

4. If there are two entries (e.g. with a .bak) at the end for the SID in question, or the SID in question ends in .bak, ensure to follow carefully the steps in the KB947215 article.
5. Reset the values for RefCount and State to be 0.
6. Reboot.
7. Retry the SQL Server installation.

On Linux and Mac OS, the following works,

:%s/^V^M/^V^M/g

where ^V^M means type Ctrl+V, then Ctrl+M.

_{Note: on Windows you probably want to use ^Q instead of ^V, since by default ^V is mapped to paste text.}

Assign the onclick like this:

divTag.onclick = printWorking;

The onclick property will not take a string when assigned. Instead, it takes a function reference (in this case, printWorking).
The onclick attribute can be a string when assigned in HTML, e.g. <div onclick="func()"></div>, but this is generally not recommended.

My god, so much mess to find version of installed .net framework?

Windows > Search > Visual Studio Installer > for installed version of VS, tap on More > Modify > Individual Components and see it there:

`pip -v` or `pip --v` 

However note, if you are using macos catelina which has the zsh (z shell) it might give you a whole bunch of things, so the best option is to try install the version or start as -- pip3

You need to compare, not assign:

if (strcmp("hello", "hello") == 0)
                             ^

Because you want to check if the result of strcmp("hello", "hello") equals to 0.

About the error:

lvalue required as left operand of assignment

lvalue means an assignable value (variable), and in assignment the left value to the = has to be lvalue (pretty clear).

Both function results and constants are not assignable (rvalues), so they are rvalues. so the order doesn't matter and if you forget to use == you will get this error. (edit:)I consider it a good practice in comparison to put the constant in the left side, so if you write = instead of ==, you will get a compilation error. for example:

int a = 5;
if (a = 0) // Always evaluated as false, no error.
{
    //...
}

vs.

int a = 5;
if (0 = a) // Generates compilation error, you cannot assign a to 0 (rvalue)
{
    //...
}

(see first answer to this question: https://stackoverflow.com/questions/2349378/new-programming-jargon-you-coined)

I think @Flo254 chained $salt to $password1and stored them to $hashed variable. $hashed variable goes inside INSERT query with $salt.

The entity type 'DisplayFormatAttribute' requires a primary key to be defined.

In my case I figured out the problem was that I used properties like this:

public string LastName { get; set; }  //OK
public string Address { get; set; }   //OK 
public string State { get; set; }     //OK
public int? Zip { get; set; }         //OK
public EmailAddressAttribute Email { get; set; } // NOT OK
public PhoneAttribute PhoneNumber { get; set; }  // NOT OK

Not sure if there is a better way to solve it but I changed the Email and PhoneNumber attribute to a string. Problem solved.

As you're passing true as the second parameter to json_decode, in the above example you can retrieve data doing something similar to:

<?php
$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

var_dump(json_decode($json));
var_dump(json_decode($json, true));

?>

function Vcount() {
var modify = document.getElementById("C_name1").value;
var oTable = document.getElementById('dataTable');
var i;
var rowLength = oTable.rows.length;
for (i = 1; i < rowLength; i++) {
    var oCells = oTable.rows.item(i).cells;
    if (modify == oCells[0].firstChild.data) {
        document.getElementById("Error").innerHTML = "  * duplicate value";
        return false;
        break;
    }

}

With Python 3.8, it's very easy.

https://docs.python.org/3/library/math.html#math.dist

math.dist(p, q)

Return the Euclidean distance between two points p and q, each given as a sequence (or iterable) of coordinates. The two points must have the same dimension.

Roughly equivalent to:

sqrt(sum((px - qx) ** 2.0 for px, qx in zip(p, q)))

Yes, the syntax is accurate and it should be fine.

Here is the SQL Fiddle Demo I created for your particular case

create table sample2
(
    id int primary key,
    created_date date,
    data varchar(10)
  )

insert into sample2 values (1,'2012-01-01','testing');

And here is how to select the data

SELECT Created_Date
FROM sample2
WHERE Created_Date >= DATEADD(day,-11117, GETDATE())

You can also do it with the keyboard shortcut shown under the simulator menu bar (Hardware-> Home).

The shortcut is ?+?+H, but you need to hit H twice in a row for it to simulate the double press that shows the apps.

Try this simple method....

Step 1:To change in single viewController

[[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleBlackOpaque];

Step 2: To change in whole application

info.plist
      ----> Status Bar Style
                  --->UIStatusBarStyle to UIStatusBarStyleBlackOpaque

Step 3: Also add this in each viewWillAppear to adjust statusbar height for iOS7

    [[UIApplication sharedApplication]setStatusBarStyle:UIStatusBarStyleLightContent];
    if ([[UIDevice currentDevice].systemVersion floatValue] >= 7) {
        CGRect frame = [UIScreen mainScreen].bounds;
        frame.origin.y+=20.0;
        frame.size.height-= 20.0;
        self.view.frame = frame;
        [self.view layoutIfNeeded];
    }
