Close the modal with universal $().hide() method:

$('#product-options').hide();

Container widths will drop down to 940 pixels for viewports less than 992 pixels. If you really don’t want containers larger than 940 pixels wide, then go to the Bootstrap customize page, and set @container-lg-desktop to either @container-desktop or hard-coded 940px.

You can't install Integration Services with it. Express does not support Integration Services. So if you want build say SSIS-packages you'll need at least Standard Edition.

See more here.

You have to use ':' colon instead of ';' semicolon.

As it stands now you try to execute the jar file which has not the execute bit set, hence the Permission denied.

And the variable must be CLASSPATH not classpath.

I would use

like 'Express Edition%'

Example:

DECLARE @edition varchar(50); 
set @edition = cast((select SERVERPROPERTY ('edition')) as varchar)

DECLARE @isExpress bit
if @edition like 'Express Edition%'
    set @isExpress = 1;
else
    set @isExpress = 0;

print @isExpress

I redirect stderr to stdout and then use grep's invert-match (-v) to exclude the warning/error string that I want to hide:

grep -r <pattern> * 2>&1 | grep -v "No such file or directory"

Steps to manually configure DNS:

1. You can access Network and Sharing center by right clicking on the Network icon on the taskbar.

2. Now choose adapter settings from the side menu.

3. This will give you a list of the available network adapters in the system . From them right click on the adapter you are using to connect to the internet now and choose properties option.

4. In the networking tab choose ‘Internet Protocol Version 4 (TCP/IPv4)’.

5. Now you can see the properties dialogue box showing the properties of IPV4. Here you need to change some properties.

   Select ‘use the following DNS address’ option. Now fill the following fields as given here.

   Preferred DNS server: 208.67.222.222

   Alternate DNS server : 208.67.220.220

   This is an available Open DNS address. You may also use google DNS server addresses.

   After filling these fields. Check the ‘validate settings upon exit’ option. Now click OK.

You have to add this DNS server address in the router configuration also (by referring the router manual for more information).

Refer : for above method & alternative

If none of this works, then open command prompt(Run as Administrator) and run these:

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
NETSH winsock reset catalog
NETSH int ipv4 reset reset.log
NETSH int ipv6 reset reset.log
Exit

Hopefully that fixes it, if its still not fixed there is a chance that its a NIC related issue(driver update or h/w).

Also FYI, this has a thread on Microsoft community : Windows 10 - DNS Issue

Use CSS3 2D transform to avoid performance issues (mobile)

A common pitfall is to animate left/top/right/bottom properties instead of using css-transform to achieve the same effect. For a variety of reasons, the semantics of transforms make them easier to offload, but left/top/right/bottom are much more difficult.

The error message is confusing for one big reason:

Primitive type names are not reserved in PHP

The following are all valid class declarations:

class string { }
class int { }
class float { }
class double { }

My mistake was in thinking that the error message was referring solely to the string primitive type - the word 'instance' should have given me pause. An example to illustrate further:

class string { }
$n = 1234;
$s1 = (string)$n;
$s2 = new string();
$a = array('no', 'yes');
printf("\$s1 - primitive string? %s - string instance? %s\n",
        $a[is_string($s1)], $a[is_a($s1, 'string')]);
printf("\$s2 - primitive string? %s - string instance? %s\n",
        $a[is_string($s2)], $a[is_a($s2, 'string')]);

Output:

$s1 - primitive string? yes - string instance? no

$s2 - primitive string? no - string instance? yes

In PHP it's possible for a string to be a string except when it's actually a string. As with any language that uses implicit type conversion, context is everything.

Using Selectors

You can get all checked checkboxes like this:

var boxes = $(":checkbox:checked");

And all non-checked like this:

var nboxes = $(":checkbox:not(:checked)");

You could merely cycle through either one of these collections, and store those names. If anything is absent, you know it either was or wasn't checked. In PHP, if you had an array of names which were checked, you could simply do an in_array() request to know whether or not any particular box should be checked at a later date.

Serialize

jQuery also has a serialize method that will maintain the state of your form controls. For instance, the example provided on jQuery's website follows:

single=Single2&multiple=Multiple&multiple=Multiple3&check=check2&radio=radio2

This will enable you to keep the information for which elements were checked as well.

Alex made a great point on readability. Equivalently, a function is also interface enough to define the type(s) being returned and you also get meaningful variable names.

delegate void OpDelegate(int op);
Task<bool> GetDataTaskAsync(OpDelegate callback)
{
    bool canGetData = true;
    if (canGetData) callback(5);
    return Task.FromResult(canGetData);
}

Callers provide a lambda (or a named function) and intellisense helps by copying the variable name(s) from the delegate.

int myOp;
bool result = await GetDataTaskAsync(op => myOp = op);

This particular approach is like a "Try" method where myOp is set if the method result is true. Otherwise, you don't care about myOp.

If you're using jQuery, you can use this to find out if an element is active:

$("input#id").is(":active");

A good way to findout what header file you are missing:

 man <section> <function call>

To find out the section use:

apropos <function call>

Example:

 man 3 memset
 man 2 send

Edit in response to James Morris:

• Section | Description
• 1 General commands
• 2 System calls
• 3 C library functions
• 4 Special files (usually devices, those found in /dev) and drivers
• 5 File formats and conventions
• 6 Games and screensavers
• 7 Miscellanea
• 8 System administration commands and daemons

For the current MS SQL JDBC driver (6.4.0) tested under Windows 7 from within DataGrip:

1. as per documentation on authenticationScheme use fully qualified domain name as host e.g. server.your.domain not just server; the documentation also mentions the possibility to specify serverSpn=MSSQLSvc/fqdn:port@REALM, but I can not provide you with details on how to use this. When specifying a fqdn as host the spn is auto-generated.
2. set authenticationScheme=JavaKerberos
3. set integratedSecurity=true
4. use your unqualified user-name (and password) to log in

As this is using JavaKerberos I would appreciate feedback on whether or not this works from outside Windows. I believe that no .dll is needed, but as I used DataGrip to create the connection I am uncertain; I would also appreciate Feedback on this!

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

• Achartengine: I have used this. Although for real time graph this might not give good performance if you do not tweak properly.

changing the width of the image will automatically change the height...

how many pictures do you want to have this functionality? If it's a lot and they all have DIFFERENT Heights you should probably just let the height change as well.

Lets say you have 5 images that have height 400px , in your html give those five tags the class of fixed

.fixed { width: 100%; height: 500px !important }

This should let the width change but keep the height the same.

In my case, I have given this attribute to the input tag

data-date-start-date="0d" data-date-end-date="0d"

This gives me the same error as trying to split the list up and zip it. ValueError: dictionary update sequence element #0 has length 1916; 2 is required

THAT is your actual question.

The answer is that the elements of your list are not what you think they are. If you type myList[0] you will find that the first element of your list is not a two-tuple, e.g. ('A', 1), but rather a 1916-length iterable.

Once you actually have a list in the form you stated in your original question (myList = [('A',1),('B',2),...]), all you need to do is dict(myList).

You can also use:

dat1 = pd.concat([dat1, dat2], axis=1)

you don't need to pass the entire encoded string to atob method, you need to split the encoded string and pass the required string to atob method

RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code.

Normally, the exe can be found in the debug folder, as suggested previously, but not in the release folder, that is disabled by default in my configuration. If you want to activate the release folder, you can do this: BUILD->Batch Build And activate the "build" checkbox in the release configuration. When you click the build button, the exe with some dependencies will be generated. Now you can copy and use it.

Your regex pattern should have the g modifier:

var pattern = /[somepattern]+/g;

notice the g at the end. it tells the replacer to do a global replace.

Also you dont need to use the RegExp object you can construct your pattern as above. Example pattern:

var pattern = /[0-9a-zA-Z]+/g;

a pattern is always surrounded by / on either side - with modifiers after the final /, the g modifier being the global.

EDIT: Why does it matter if pattern is a variable? In your case it would function like this (notice that pattern is still a variable):

var pattern = /[0-9a-zA-Z]+/g;
repeater.replace(pattern, "1234abc");

But you would need to change your replace function to this:

this.markup = this.markup.replace(pattern, value);

Use match instead, and the g flag.

str.match(/<b>(.*?)<\/b>/g);

The above answer by pl_rock is correct, the only thing I would add is to expect the ARG inside the Dockerfile if not you won't have access to it. So if you are doing

docker build -t essearch/ess-elasticsearch:1.7.6 --build-arg number_of_shards=5 --build-arg number_of_replicas=2 --no-cache .

Then inside the Dockerfile you should add

ARG number_of_replicas
ARG number_of_shards

I was running into this problem, so I hope I help someone (myself) in the future.

You need to run the script like this:

groovy helloworld.groovy

Also, if you want to overwrite messages in the same line, for instance in a countdown, you could add '\r' at the end of the string.

process.stdout.write("Downloading " + data.length + " bytes\r");

h5py provides a model of datasets and groups. The former is basically arrays and the latter you can think of as directories. Each is named. You should look at the documentation for the API and examples:

http://docs.h5py.org/en/latest/quick.html

A simple example where you are creating all of the data upfront and just want to save it to an hdf5 file would look something like:

In [1]: import numpy as np
In [2]: import h5py
In [3]: a = np.random.random(size=(100,20))
In [4]: h5f = h5py.File('data.h5', 'w')
In [5]: h5f.create_dataset('dataset_1', data=a)
Out[5]: <HDF5 dataset "dataset_1": shape (100, 20), type "<f8">

In [6]: h5f.close()

You can then load that data back in using: '

In [10]: h5f = h5py.File('data.h5','r')
In [11]: b = h5f['dataset_1'][:]
In [12]: h5f.close()

In [13]: np.allclose(a,b)
Out[13]: True

Definitely check out the docs:

http://docs.h5py.org

Writing to hdf5 file depends either on h5py or pytables (each has a different python API that sits on top of the hdf5 file specification). You should also take a look at other simple binary formats provided by numpy natively such as np.save, np.savez etc:

http://docs.scipy.org/doc/numpy/reference/routines.io.html

I think that this construct: if exists (select... is specific for MS SQL. In MySQL EXISTS predicate tells you whether the subquery finds any rows and it's used like this: SELECT column1 FROM t1 WHERE EXISTS (SELECT * FROM t2);

You can rewrite the above lines of code like this:

DELIMITER $$

CREATE PROCEDURE `checando`(in nombrecillo varchar(30), in contrilla varchar(30), out resultado int)

BEGIN
    DECLARE count_prim INT;
    DECLARE count_sec INT;

    SELECT COUNT(*) INTO count_prim FROM compas WHERE nombre = nombrecillo AND contrasenia = contrilla;
    SELECT COUNT(*) INTO count_sec FROM FROM compas WHERE nombre = nombrecillo;

    if (count_prim > 0) then
        set resultado = 0;
    elseif (count_sec > 0) then
        set resultado = -1;
    else 
        set resultado = -2;
    end if;
    SELECT resultado;
END

In my case was a comma at the end of every line. By removing that worked

MongoDB needs data directory to store data. Default path is /data/db

When you start MongoDB engine, it searches this directory which is missing in your case. Solution is create this directory and assign rwx permission to user.

If you want to change the path of your data directory then you should specify it while starting mongod server like,

mongod --dbpath /data/<path> --port <port no> 

This should help you start your mongod server with custom path and port.

I still cannot make this work. Any other ideas?

This is a classic difficulty in LaTeX.

The problem is how to do layout with floats (figures and tables, an similar objects) and footnotes. In particular, it is hard to pick a place for a float with certainty that making room for the associated footnotes won't cause trouble. So the standard tabular and figure environments don't even try.

What can you do:

1. Fake it. Just put a hardcoded vertical skip at the bottom of the caption and then write the footnote yourself (use \footnotesize for the size). You also have to manage the symbols or number yourself with \footnotemark. Simple, but not very attractive, and the footnote does not appear at the bottom of the page.
2. Use the tabularx, longtable, threeparttable[x] (kudos to Joseph) or ctable which support this behavior.
3. Manage it by hand. Use [h!] (or [H] with the float package) to control where the float will appear, and \footnotetext on the same page to put the footnote where you want it. Again, use \footnotemark to install the symbol. Fragile and requires hand-tooling every instance.
4. The footnotes package provides the savenote environment, which can be used to do this.
5. Minipage it (code stolen outright, and read the disclaimer about long caption texts in that case):

    \begin{figure}
      \begin{minipage}{\textwidth}
        ...
        \caption[Caption for LOF]%
          {Real caption\footnote{blah}}
      \end{minipage}
    \end{figure}

There also exists a 'JVM Debugger Memory View' found in the plugin repository, which could be useful.

you can just do

select rownum, l.* from student  l where name like %ram%

this assigns the row number as the rows are fetched (so no guaranteed ordering of course).

if you wanted to order first do:

select rownum, l.*
  from (select * from student l where name like %ram% order by...) l;

You can also use $("ul li:first-child") to only get the direct children of the UL.

I agree though, you need an ID or something else to identify the main UL otherwise it will just select them all. If you had a div with an ID around the UL the easiest thing to do would be$("#someDiv > ul > li")

The value of the match attribute of the <xsl:template> instruction must be a match pattern.

Match patterns form a subset of the set of all possible XPath expressions. The first, natural, limitation is that a match pattern must select a set of nodes. There are also other limitations. In particular, reverse axes are not allowed in the location steps (but can be specified within the predicates). Also, no variable or parameter references are allowed in XSLT 1.0, but using these is legal in XSLT 2.x.

/ in XPath denotes the root or document node. In XPath 2.0 (and hence XSLT 2.x) this can also be written as document-node().

A match pattern can contain the // abbreviation.

Examples of match patterns:

<xsl:template match="table">

can be applied on any element named table.

<xsl:template match="x/y">

can be applied on any element named y whose parent is an element named x.

<xsl:template match="*">

can be applied to any element.

<xsl:template match="/*">

can be applied only to the top element of an XML document.

<xsl:template match="@*">

can be applied to any attribute.

<xsl:template match="text()">

can be applied to any text node.

<xsl:template match="comment()">

can be applied to any comment node.

<xsl:template match="processing-instruction()">

can be applied to any processing instruction node.

<xsl:template match="node()">

can be applied to any node: element, text, comment or processing instructon.

Use:

System.Security.Principal.WindowsIdentity.GetCurrent().Name

That will be the logon name.

You are using improper syntax. If you read the docs mysqli_query() you will find that it needs two parameter.

mixed mysqli_query ( mysqli $link , string $query [, int $resultmode = MYSQLI_STORE_RESULT ] )

mysql $link generally means, the resource object of the established mysqli connection to query the database.

So there are two ways of solving this problem

mysqli_query();

$myConnection= mysqli_connect("$db_host","$db_username","$db_pass", "mrmagicadam") or die ("could not connect to mysql"); 
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysqli_query($myConnection, $sqlCommand) or die(mysqli_error($myConnection));

Or, Using mysql_query() (This is now obselete)

$myConnection= mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");
mysql_select_db("mrmagicadam") or die ("no database");        
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysql_query($sqlCommand) or die(mysql_error());

As pointed out in the comments, be aware of using die to just get the error. It might inadvertently give the viewer some sensitive information .

GO
EXEC sp_send_dbmail @profile_name='yourprofilename',
@recipients='[email protected]',
@subject='Test message',
@body='This is the body of the test message.
Congrates Database Mail Received By you Successfully.'

To loop through the table

DECLARE @email_id NVARCHAR(450), @id BIGINT, @max_id BIGINT, @query NVARCHAR(1000)

SELECT @id=MIN(id), @max_id=MAX(id) FROM [email_adresses]

WHILE @id<=@max_id

In my case I wanted to use a Swift protocol in an Objective-C header file that comes from the same target and for this I needed to use a forward declaration of the Swift protocol to reference it in the Objective-C interface. The same should be valid for using a Swift class in an Objective-C header file. To use forward declaration see the following example from the docs at Include Swift Classes in Objective-C Headers Using Forward Declarations:

// MyObjcClass.h
@class MySwiftClass; // class forward declaration
@protocol MySwiftProtocol; // protocol forward declaration

@interface MyObjcClass : NSObject
- (MySwiftClass *)returnSwiftClassInstance;
- (id <MySwiftProtocol>)returnInstanceAdoptingSwiftProtocol;
// ...

                CustomData val2 = map.get(rhs);

                    return (val2 != null) ? 1 : 0;
                } else if (val1 != null) && (val2 != null)) {

I'll put in my two cents for tapply().

tapply(df$dt, df$group, summary)

You could write a custom function with the specific statistics you want to replace summary.

Are you just looking to verify that the file is of a given extension? You can simplify what you are trying to do with something like this:

(.*?)\.(jpg|gif|doc|pdf)$

Then, when you call IsMatch() make sure to pass RegexOptions.IgnoreCase as your second parameter. There is no reason to have to list out the variations for casing.

Edit: As Dario mentions, this is not going to work for the RegularExpressionValidator, as it does not support casing options.

Try using this code:

var datetime = 1383066000000; // anything
var date = new Date(datetime);
var options = {
        year: 'numeric', month: 'numeric', day: 'numeric',
    };

var result = date.toLocaleDateString('en', options); // 10/29/2013

See more: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleDateString

These all seem like very complicated answers for a very simple function:

public bool IsWindows7 
{ 
    get 
    { 
        return (Environment.OSVersion.Version.Major == 6 &
            Environment.OSVersion.Version.Minor == 1); 
    } 
}

Without explicitly providing the type as in command.Parameters.Add("@ID", SqlDbType.Int);, it will try to implicitly convert the input to what it is expecting.

The downside of this, is that the implicit conversion may not be the most optimal of conversions and may cause a performance hit.

There is a discussion about this very topic here: http://forums.asp.net/t/1200255.aspx/1

You can achieve this with the background-size property, which is now supported by most browsers.

To scale the background image to fit inside the div:

background-size: contain;

To scale the background image to cover the whole div:

background-size: cover;

I've found that, providing you have an access token, you can perform the following request in your browser:

https://api.instagram.com/v1/users/self?access_token=[VALUE]

In fact, access token contain the User ID (the first segment of the token):

<user-id>.1677aaa.aaa042540a2345d29d11110545e2499

You can get an access token by using this tool provided by Pixel Union.

The document.domain method

• Method type: iframe.

Note that this is an iframe method that sets the value of document.domain to a suffix of the current domain. If it does so, the shorter domain is used for subsequent origin checks. For example, assume a script in the document at http://store.company.com/dir/other.html executes the following statement:

document.domain = "company.com";

After that statement executes, the page would pass the origin check with http://company.com/dir/page.html. However, by the same reasoning, company.com could not set document.domain to othercompany.com.

With this method, you would be allowed to exectue javascript from an iframe sourced on a subdomain on a page sourced on the main domain. This method is not suited for cross-domain resources as browsers like Firefox will not allow you to change the document.domain to a completely alien domain.

The Cross-Origin Resource Sharing method

• Method type: AJAX.

Cross-Origin Resource Sharing (CORS) is a W3C Working Draft that defines how the browser and server must communicate when accessing sources across origins. The basic idea behind CORS is to use custom HTTP headers to allow both the browser and the server to know enough about each other to determine if the request or response should succeed or fail.

For a simple request, one that uses either GET or POST with no custom headers and whose body is text/plain, the request is sent with an extra header called Origin. The Origin header contains the origin (protocol, domain name, and port) of the requesting page so that the server can easily determine whether or not it should serve a response. An example Origin header might look like this:

Origin: http://www.stackoverflow.com

If the server decides that the request should be allowed, it sends a Access-Control-Allow-Origin header echoing back the same origin that was sent or * if it’s a public resource. For example:

Access-Control-Allow-Origin: http://www.stackoverflow.com

If this header is missing, or the origins don’t match, then the browser disallows the request. If all is well, then the browser processes the request. Note that neither the requests nor responses include cookie information.

The Mozilla team suggests in their post about CORS that you should check for the existence of the withCredentials property to determine if the browser supports CORS via XHR. You can then couple with the existence of the XDomainRequest object to cover all browsers:

function createCORSRequest(method, url){
    var xhr = new XMLHttpRequest();
    if ("withCredentials" in xhr){
        xhr.open(method, url, true);
    } else if (typeof XDomainRequest != "undefined"){
        xhr = new XDomainRequest();
        xhr.open(method, url);
    } else {
        xhr = null;
    }
    return xhr;
}

var request = createCORSRequest("get", "http://www.stackoverflow.com/");
if (request){
    request.onload = function() {
        // ...
    };
    request.onreadystatechange = handler;
    request.send();
}

Note that for the CORS method to work, you need to have access to any type of server header mechanic and can't simply access any third-party resource.

The window.postMessage method

• Method type: iframe.

window.postMessage, when called, causes a MessageEvent to be dispatched at the target window when any pending script that must be executed completes (e.g. remaining event handlers if window.postMessage is called from an event handler, previously-set pending timeouts, etc.). The MessageEvent has the type message, a data property which is set to the string value of the first argument provided to window.postMessage, an origin property corresponding to the origin of the main document in the window calling window.postMessage at the time window.postMessage was called, and a source property which is the window from which window.postMessage is called.

To use window.postMessage, an event listener must be attached:

    // Internet Explorer
    window.attachEvent('onmessage',receiveMessage);

    // Opera/Mozilla/Webkit
    window.addEventListener("message", receiveMessage, false);

And a receiveMessage function must be declared:

function receiveMessage(event)
{
    // do something with event.data;
}

The off-site iframe must also send events properly via postMessage:

<script>window.parent.postMessage('foo','*')</script>

Any window may access this method on any other window, at any time, regardless of the location of the document in the window, to send it a message. Consequently, any event listener used to receive messages must first check the identity of the sender of the message, using the origin and possibly source properties. This cannot be understated: Failure to check the origin and possibly source properties enables cross-site scripting attacks.

I've tried all of the above nothing was working.. so I had to make my ImageView static public static ImageView texture; and then texture = (ImageView) findViewById(R.id.texture_back); , I don't think it's a good approach though but this really worked for my case :)

I find the solution for listbox items' background to yellow. I tried the following solution to achieve the output.

 for (int i = 0; i < lstEquipmentItem.Items.Count; i++)
                {
                    if ((bool)ds.Tables[0].Rows[i]["Valid_Equipment"] == false)
                    {
                        lblTKMWarning.Text = "Invalid Equipment & Serial Numbers are highlited.";
                        lblTKMWarning.ForeColor = System.Drawing.Color.Red;
                        lstEquipmentItem.Items[i].Attributes.Add("style", "background-color:Yellow");
                        Count++;
                    }

                }

Image can not be shown until it serves from any server. so you need to upload the image to your server to show its preview.

I think this might help you...

(function ( $ ) {_x000D_
  _x000D_
    $.fn.highlight = function( options ) {_x000D_
  _x000D_
        // This is the easiest way to have default options._x000D_
        var settings = $.extend({_x000D_
            // These are the defaults._x000D_

        // Highlight the collection based on the settings variable._x000D_
        return this.css({_x000D_

        });_x000D_
  _x000D_
    };_x000D_
  _x000D_
}( jQuery ));

In the above example i had created a simple jquery highlight plugin.I had shared an article in which i had discussed about How to Create Your Own jQuery Plugin from Basic to Advance. I think you should check it out... http://mycodingtricks.com/jquery/how-to-create-your-own-jquery-plugin/

In most project types, your async "up" and "down" will end at an async void event handler or returning a Task to your framework.

However, Console apps do not support this.

You can either just do a Wait on the returned task:

static void Main()
{
  MainAsync().Wait();
  // or, if you want to avoid exceptions being wrapped into AggregateException:
  //  MainAsync().GetAwaiter().GetResult();
}

static async Task MainAsync()
{
  ...
}

or you can use your own context like the one I wrote:

static void Main()
{
  AsyncContext.Run(() => MainAsync());
}

static async Task MainAsync()
{
  ...
}

More information for async Console apps is on my blog.

This is an old post but I have issues with coming across posts that have some incorrect information/syntax...

If you wanted to do this with a shorcut icon you could just create a shortcut on your desktop for the cmd.exe application. Then append a /K {your command} to the shorcut path.

So a default shorcut target path may look like "%windir%\system32\cmd.exe", just change it to %windir%\system32\cmd.exe /k {commands}

example: %windir%\system32\cmd.exe /k powercfg -lastwake

In this case i would use /k (keep open) to display results.

Arlen was right about the /k (keep open) and /c (close)

You can open a command prompt and type "cmd /?" to see your options.

http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/cmd.mspx?mfr=true

A batch file is kind of overkill for a single command prompt command...

Hope this helps someone else

All you needed was a plus :)

$("#Restaurant_Name").keyup(function(){
        var Text = $(this).val();
        Text = Text.toLowerCase();
        var regExp = /\s+/g;
        Text = Text.replace(regExp,'-');
        $("#Restaurant_Slug").val(Text);        
});

Android just makes little things too complicated unfortunately. Easiest way to achieve what you want, without implementing DividerItemDecoration here:

Add background color to the RecyclerView to your desired divider color:

<RecyclerView
    android:id="@+id/rvList"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="@color/colorLightGray"
    android:scrollbars="vertical"
    tools:listitem="@layout/list_item"
    android:background="@android:color/darker_gray"/>

Add bottom margin (android:layout_marginBottom) to the layout root of the item (list_item.xml):

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginBottom="1dp">

    <TextView
        android:id="@+id/tvName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="John Doe" />

    <TextView
        android:id="@+id/tvDescription"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/tvName"
        android:text="Some description blah blah" />

</RelativeLayout>

This should give 1dp space between the items and the background color of RecyclerView (which is dark gray would appear as divider).

docker cp containerId:source_path destination_path

containerId can be obtained from the command docker ps -a

source path should be absolute. for example, if the application/service directory starts from the app in your docker container the path would be /app/some_directory/file

example : docker cp d86844abc129:/app/server/output/server-test.png C:/Users/someone/Desktop/output

Going by the comments as well as personal experience, I say no, there is no need for range(len(a)). Everything you can do with range(len(a)) can be done in another (usually far more efficient) way.

You gave many examples in your post, so I won't repeat them here. Instead, I will give an example for those who say "What if I want just the length of a, not the items?". This is one of the only times you might consider using range(len(a)). However, even this can be done like so:

>>> a = [1, 2, 3, 4]
>>> for _ in a:
...     print True
...
True
True
True
True
>>>

Clements answer (as shown by Allik) can also be reworked to remove range(len(a)):

>>> a = [6, 3, 1, 2, 5, 4]
>>> sorted(range(len(a)), key=a.__getitem__)
[2, 3, 1, 5, 4, 0]
>>> # Note however that, in this case, range(len(a)) is more efficient.
>>> [x for x, _ in sorted(enumerate(a), key=lambda i: i[1])]
[2, 3, 1, 5, 4, 0]
>>>

So, in conclusion, range(len(a)) is not needed. Its only upside is readability (its intention is clear). But that is just preference and code style.

It because every time

void pthread_exit(void *ret);

will be called from thread function so which ever you want to return simply its pointer pass with pthread_exit().

Now at

int pthread_join(pthread_t tid, void **ret);

will be always called from where thread is created so here to accept that returned pointer you need double pointer ..

i think this code will help you to understand this

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

void* thread_function(void *ignoredInThisExample)
{
    char *a = malloc(10);
    strcpy(a,"hello world");
    pthread_exit((void*)a);
}
int main()
{
    pthread_t thread_id;
    char *b;

    pthread_create (&thread_id, NULL,&thread_function, NULL);

    pthread_join(thread_id,(void**)&b); //here we are reciving one pointer 
                                        value so to use that we need double pointer 
    printf("b is %s\n",b); 
    free(b); // lets free the memory

}

You can add "issue time" to token and maintain "last logout time" for each user on the server. When you check token validity, also check "issue time" be after "last logout time".

[0, 132, 432, 342, 234][1..-1]
=> [132, 432, 342, 234]

So unlike shift or slice this returns the modified array (useful for one liners).

I think this link demonstrates the best way to get application context anywhere, even in the non-bean class. I find it very useful. Hope its the same for you. The below is the abstract code of it

Create a new class ApplicationContextProvider.java

package com.java2novice.spring;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class ApplicationContextProvider implements ApplicationContextAware{

    private static ApplicationContext context;

    public static ApplicationContext getApplicationContext() {
        return context;
    }

    @Override
    public void setApplicationContext(ApplicationContext ac)
            throws BeansException {
        context = ac;
    }
}

Add an entry in application-context.xml

<bean id="applicationContextProvider"
                        class="com.java2novice.spring.ApplicationContextProvider"/>

In annotations case (instead of application-context.xml)

@Component
public class ApplicationContextProvider implements ApplicationContextAware{
...
}

Get the context like this

TestBean tb = ApplicationContextProvider.getApplicationContext().getBean("testBean", TestBean.class);

Cheers!!

I also get an EXC_BAD_ACCESS problem.The value in objc_getAssociatedObject() and objc_setAssociatedObject() should be an Object. And the objc_AssociationPolicy should match the Object.

Since fields or fns are cell arrays, you have to index with curly brackets {} in order to access the contents of the cell, i.e. the string.

Note that instead of looping over a number, you can also loop over fields directly, making use of a neat Matlab features that lets you loop through any array. The iteration variable takes on the value of each column of the array.

teststruct = struct('a',3,'b',5,'c',9)

fields = fieldnames(teststruct)

for fn=fields'
  fn
  %# since fn is a 1-by-1 cell array, you still need to index into it, unfortunately
  teststruct.(fn{1})
end

See my solution here: "Junit and java 7."

In this article I describe how to run junit tests in order - "just as in your source code". Tests will be run, in order as your test methods appears in class file.

http://intellijava.blogspot.com/2012/05/junit-and-java-7.html

But as Pascal Thivent said, this is not a good practise.

With Typescript 3.0 there is a new solution to this issue:

export interface Props {
    name: string;
}

export class Greet extends React.Component<Props> {
    render() {
        const { name } = this.props;
        return <div>Hello ${name.toUpperCase()}!</div>;
    }
    static defaultProps = { name: "world"};
}

// Type-checks! No type assertions needed!
let el = <Greet />

Note that for this to work you need a newer version of @types/react than 16.4.6. It works with 16.4.11.

For those who are able to access cpanel, there is a simpler way getting around it.

1. log in cpanel => "Remote MySQL" under DATABASES section:

2. Add the IPs / hostname which you are accessing from

3. done!!!

If you're using jQuery 2.1.4 or above, try this:

$("#" + this.d);

Or, you can define var before using it. It makes your code simpler.

var d = this.d
$("#" + d);

Plus, you should make sure the MySQL server's config (/etc/mysql/my.cnf, /etc/default/mysql on Debian) doesn't have "skip-networking" activated and is not binded exclusively to the loopback interface (127.0.0.1) but also to the interface/IP address you want connect to.

This side effect can happen indirectly. F.e. as a consequence of the linked data model being changed in a way this method is called, after properties are set.

I faced exactly the same issue in a Spring web app. In fact, I had removed spring-security by commenting the config annotation:

// @ImportResource({"/WEB-INF/spring-security.xml"})

but I had forgotten to remove the corresponding filters in web.xml:

<!-- Filters --> 
<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

Commenting filters solved the issue.

Ok, first e.preventDefault(); it's not a Jquery element, it's a method of javascript, now what it's true it's if you add this method you avoid the submit the event, now what you could do it's send the form by ajax something like this

$('#subscription_order_form').submit(function(e){
    $.ajax({
     url: $(this).attr('action'),
     data : $(this).serialize(),
     success : function (data){

      }
   });
    e.preventDefault();
});

For Upgradation php in Xampp you can follow this steps, Else you can skip these 4 steps and direct install MAMP (for windows as well) from site and here is the direct download link

Step 1: Make backups Before starting, make sure to backup any settings, custom modules and most importantly the htdocs directory, which contains your scripts and page resources. This directory is normally located atC:\xampp\htdocs\

Step 2: Preparation

Download PHP 5.3.0rc2. I use the VC6 build in order to minimise any potential compatibility issues. It is also recommended that you download the latest Windows version of XAMPP. While this is an upgrade guide that shouldwork with previous versions of XAMPP, it is recommended that a fresh copy of the core files is used. Stop any instances of the Apache service that might be running.

Step 3: The upgrade This guide will assume your XAMPP directory is C:\xampp\

Extract the XAMPP archive to a directory of your choosing, I would recommend using the default C:\xampp\ Extract the contents of the PHP archive to C:\xampp\php\, overwriting the contents of this directory with the new files. Open the file C:\xampp\apache\conf\extra\httpd-xampp.conf and ensure the following lines are present in this order:

LoadFile "/xampp/php/php5ts.dll"
LoadModule php5_module "/xampp/apache/bin/php5apache2_2.dll"

Replace C:\xampp\php\php.ini with C:\xampp\php\php.ini-dist
Uncomment the lines:

;extension=php_mbstring.dll
;extension=php_pdo_sqlite.dll

Replace the line

magic_quotes_gpc = On

with

magic_quotes_gpc = Off

Copy all files in the C:\xampp\php\ to C:\xampp\apache\bin\ (do not copy the subdirectories or their contents).

After following the above steps, restart your Apache service (this can be done using C:\xampp\xampp-control.exe or manually through the control panel/command prompt). Your PHPinfo should indicate that the upgrade has been successful. I will update this post if I discover any problems from using this method, or a cleaner (automated) means of performing the upgrade.

Do it the vi way.

To delete 5 lines press: 5dd ( 5 delete )

To select ( actually copy them to the clipboard ) you type: 10yy

It is a bit hard to grasp, but very handy to learn when using those remote terminals

Be aware of the learning curves for some editors:

_{(source: calver at unix.rulez.org)}

simplest way(and even works from api 1) that tested is:

getResources().getDimensionPixelSize(R.dimen.example_dimen);

From documentations:

Retrieve a dimensional for a particular resource ID for use as a size in raw pixels. This is the same as getDimension(int), except the returned value is converted to integer pixels for use as a size. A size conversion involves rounding the base value, and ensuring that a non-zero base value is at least one pixel in size.

Yes it rounding the value but it's not very bad(just in odd values on hdpi and ldpi devices need to add a little value when ldpi is not very common) I tested in a xxhdpi device that converts 4dp to 16(pixels) and that is true.

The command [Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27", "User") is not a Python command. Instead, this is an operating system command to the set the PATH variable.

You are getting this error as you are inside the Python interpreter which was triggered by the command python you have entered in the terminal (Windows PowerShell).

Please note the >>> at the left side of the line. It states that you are on inside Python interpreter.

Please enter quit() to exit the Python interpreter and then type the command. It should work!

There's a class of question on SO that sometimes make less than perfect sense, this one is perilously close :-)

Perhaps you could explain your aversion to using one of the two methods you ruled out.

If it's just because you don't want to pepper your code with if statements or exception catching code, one solution is to use a helper function that will take care of it for you, something like:

static String substring_safe (String s, int start, int len) { ... }

which will check lengths beforehand and act accordingly (either return smaller string or pad with spaces).

Then you don't have to worry about it in your code at all, just call:

String s2 = substring_safe (s, 10, 7);

instead of:

String s2 = s.substring (10,7);

This would work in the case that you seem to be worried about (based on your comments to other answers), not breaking the flow of the code when doing lots of string building stuff.

don't use -notLike, -notMatch with Regular-Expression works in one line:

Get-MailBoxPermission -id newsletter | ? {$_.User -NotMatch "NT-AUTORIT.*|.*-Admins|.*Administrators|.*Manage.*"}

Use this code where str is your JSON string:

NSError *err = nil;
NSArray *arr = 
 [NSJSONSerialization JSONObjectWithData:[str dataUsingEncoding:NSUTF8StringEncoding] 
                                 options:NSJSONReadingMutableContainers 
                                   error:&err];
// access the dictionaries
NSMutableDictionary *dict = arr[0];
for (NSMutableDictionary *dictionary in arr) {
  // do something using dictionary
}

For right labels use ax.yaxis.set_label_position("right"), i.e.:

f = plt.figure()
ax = f.add_subplot(111)
ax.yaxis.tick_right()
ax.yaxis.set_label_position("right")
plt.plot([2,3,4,5])
ax.set_xlabel("$x$ /mm")
ax.set_ylabel("$y$ /mm")
plt.show()

I just discovered a workaround for this problem that is so simple, and yet I haven't found any discussions anywhere that mention it. It does require control of the parent frame.

In your iFrame, say you want this iframe: src="http://www.example.com/mypage.php"

Well, instead of HTML to specify the iframe, use a javascript to build the HTML for your iframe, get the parent url through javascript "at build time", and send it as a url GET parameter in the querystring of your src target, like so:

<script type="text/javascript">
  url = parent.document.URL;
  document.write('<iframe src="http://example.com/mydata/page.php?url=' + url + '"></iframe>');
</script>

Then, find yourself a javascript url parsing function that parses the url string to get the url variable you are after, in this case it's "url".

I found a great url string parser here: http://www.netlobo.com/url_query_string_javascript.html

Trying to get this on a mobile device requires a few more steps. screen.availWidth stays the same regardless of the orientation of the device.

Here is my solution for mobile:

function getOrientation(){
    return Math.abs(window.orientation) - 90 == 0 ? "landscape" : "portrait";
};
function getMobileWidth(){
    return getOrientation() == "landscape" ? screen.availHeight : screen.availWidth;
};
function getMobileHeight(){
    return getOrientation() == "landscape" ? screen.availWidth : screen.availHeight;
};

You are experiencing this issue for two reasons.

• The JPQL Query is not valid.
• You have not created an association between your entities that the underlying JPQL query can utilize.

When performing a join in JPQL you must ensure that an underlying association between the entities attempting to be joined exists. In your example, you are missing an association between the User and Area entities. In order to create this association we must add an Area field within the User class and establish the appropriate JPA Mapping. I have attached the source for User below. (Please note I moved the mappings to the fields)

User.java

@Entity
@Table(name="user")
public class User {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="iduser")
    private Long idUser;

    @Column(name="user_name")
    private String userName;

    @OneToOne()
    @JoinColumn(name="idarea")
    private Area area;

    public Long getIdUser() {
        return idUser;
    }

    public void setIdUser(Long idUser) {
        this.idUser = idUser;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public Area getArea() {
        return area;
    }

    public void setArea(Area area) {
        this.area = area;
    }
}

Once this relationship is established you can reference the area object in your @Query declaration. The query specified in your @Query annotation must follow proper syntax, which means you should omit the on clause. See the following:

@Query("select u.userName from User u inner join u.area ar where ar.idArea = :idArea")

While looking over your question I also made the relationship between the User and Area entities bidirectional. Here is the source for the Area entity to establish the bidirectional relationship.

Area.java

@Entity
@Table(name = "area")
public class Area {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="idarea")
    private Long idArea;

    @Column(name="area_name")
    private String areaName;

    @OneToOne(fetch=FetchType.LAZY, mappedBy="area")
    private User user;

    public Long getIdArea() {
        return idArea;
    }

    public void setIdArea(Long idArea) {
        this.idArea = idArea;
    }

    public String getAreaName() {
        return areaName;
    }

    public void setAreaName(String areaName) {
        this.areaName = areaName;
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }
}

Now, if the repository is already existing on a remote machine, and you do not have anything locally, you do git clone instead.

The URL format is simple, it is PROTOCOL:/[user@]remoteMachineAddress/path/to/repository.git

For example, cloning a repository on a machine to which you have SSH access using the "dev" user, residing in /srv/repositories/awesomeproject.git and that machine has the ip 10.11.12.13 you do:

git clone ssh://[email protected]/srv/repositories/awesomeproject.git

A shorthand answer assuming import matplotlib.pyplot as plt:

plt.gca().set_title('title')

as in:

plt.subplot(221)
plt.gca().set_title('title')
plt.subplot(222)
etc...

Then there is no need for superfluous variables.

String file = "/path/to/your/file.txt";

try {

    BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file)));
    String line;
    // Uncomment the line below if you want to skip the fist line (e.g if headers)
    // line = br.readLine();

    while ((line = br.readLine()) != null) {

        // do something with line

    }
    br.close();

} catch (IOException e) {
    System.out.println("ERROR: unable to read file " + file);
    e.printStackTrace();   
}

That will be possible only if the HTML file is also loaded with the file protocol from the local user's harddisk.

If the HTML page is served by HTTP from a server, you can't access any local files by specifying them in a src attribute with the file:// protocol as that would mean you could access any file on the users computer without the user knowing which would be a huge security risk.

As Dimitar Bonev said, you can access a file if the user selects it using a file selector on their own. Without that step, it's forbidden by all browsers for good reasons. Thus, while his answer might prove useful for many people, it loosens the requirement from the code in the original question.

Basing on Ilya's data, I wrote a Vanilla JS library for supporting modifier keys on Mac: https://github.com/MichaelZelensky/jsLibraries/blob/master/macKeys.js

Just use it like this, e.g.:

document.onclick = function (event) {
  if (event.shiftKey || macKeys.shiftKey) {
    //do something interesting
  }
}

Tested on Chrome, Safari, Firefox, Opera on Mac. Please check if it works for you.

Try any of these

RENAME TABLE `group` TO `member`;

or

ALTER TABLE `group` RENAME `member`;

If the size of the subdirectory is not particularly huge, AND you wish to stay away from the CLI, here's a quick solution to manually reset the sub-directory:

1. Switch to master branch and copy the sub-directory to be reset.
2. Now switch back to your feature branch and replace the sub-directory with the copy you just created in step 1.
3. Commit the changes.

Cheers. You just manually reset a sub-directory in your feature branch to be same as that of master branch !!

/usr/local/ssl/openssl.cnf

A path like this means the program has been compiled with either Cygwin or MSYS. If you must use this openssl then you will need an interpreter that understands those paths, like Bash, which is provided by Cygwin or MSYS.

Another option would be to download or compile a Windows Native version of openssl. Using that the program would instead require a path like

C:\Users\Steven\ssl\openssl.cnf

which would be better suited for the Command Prompt.

Whatever is specified in the command in docker-compose.yml should get appended to the entrypoint defined in the Dockerfile, provided entrypoint is defined in exec form in the Dockerfile.

If the EntryPoint is defined in shell form, then any CMD arguments will be ignored.

Presumably, you want to convert values before the decimal place to an integer. If so, use case and check for the right format:

SELECT (case when varcharcol not like '%.%' then cast(varcharcol as int)
             else cast(left(varcharcol, chardindex('.', varcharcol) - 1) as int)
        end) IntVal
FROM MyTable;

the split() method takes a regular expression as an argument

I had this problem before and I solved by :

Right click my computer -> properties -> Advanced system settings.

In both sections :

• User variables for "YourUser" &
• System variables

Update the PATH by adding to the end of it a ";" and your java bin folder location , mine was "C:\Program Files\Java\jdk1.7.0_51\bin"

If there is no path then create it using the NEW button, set "Variable Name " to PATH and "Value" to your java bin location.

You can replace your PATH if there is no need for it

NOTE : THE FOLDER BIN SHOULD CONTAIN javaw.exe

Your problem is basically that you never specified the right path to the file.

Try instead, from your main script:

from folder.file import Klasa

Or, with from folder import file:

from folder import file
k = file.Klasa()

Or again:

import folder.file as myModule
k = myModule.Klasa()

You should implement the IEnumerable interface (CarBootSaleList should impl it in your case).

http://msdn.microsoft.com/en-us/library/system.collections.ienumerable.getenumerator.aspx

But it is usually easier to subclass System.Collections.ObjectModel.Collection and friends

http://msdn.microsoft.com/en-us/library/system.collections.objectmodel.aspx

Your code also seems a bit strange, like you are nesting lists?

For anyone who doesn't like none of the solutions posted above like me then you can simply implement a timer yourself and stop the request execution by throwing a runtime exception. Something like below:

                  try 
                 {
                     timer.schedule(new TimerTask() {
                       @Override
                       public void run() {
                         timer.cancel();
                       }
                     }, /* specify time of the requst */ 1000);
                 }
                 catch(Exception e)
                 {
                   throw new RuntimeException("the request is taking longer than usual");
                 }

   

or preferably use the java guava timeLimiter here

This confusion is because URLs are still 'broken' to this day.

Take "http://www.google.com" for instance. This is a URL. A URL is a Uniform Resource Locator and is really a pointer to a web page (in most cases). URLs actually have a very well-defined structure since the first specification in 1994.

We can extract detailed information about the "http://www.google.com" URL:

+---------------+-------------------+
|      Part     |      Data         |
+---------------+-------------------+
|  Scheme       | http              |
|  Host         | www.google.com    |
+---------------+-------------------+

If we look at a more complex URL such as:

"https://bob:[email protected]:8080/file;p=1?q=2#third"

we can extract the following information:

+-------------------+---------------------+
|        Part       |       Data          |
+-------------------+---------------------+
|  Scheme           | https               |
|  User             | bob                 |
|  Password         | bobby               |
|  Host             | www.lunatech.com    |
|  Port             | 8080                |
|  Path             | /file;p=1           |
|  Path parameter   | p=1                 |
|  Query            | q=2                 |
|  Fragment         | third               |
+-------------------+---------------------+

https://bob:[email protected]:8080/file;p=1?q=2#third
\___/   \_/ \___/ \______________/ \__/\_______/ \_/ \___/
  |      |    |          |          |      | \_/  |    |
Scheme User Password    Host       Port  Path |   | Fragment
        \_____________________________/       | Query

                   Authority

The reserved characters are different for each part.

For HTTP URLs, a space in a path fragment part has to be encoded to "%20" (not, absolutely not "+"), while the "+" character in the path fragment part can be left unencoded.

Now in the query part, spaces may be encoded to either "+" (for backwards compatibility: do not try to search for it in the URI standard) or "%20" while the "+" character (as a result of this ambiguity) has to be escaped to "%2B".

This means that the "blue+light blue" string has to be encoded differently in the path and query parts:

"http://example.com/blue+light%20blue?blue%2Blight+blue".

From there you can deduce that encoding a fully constructed URL is impossible without a syntactical awareness of the URL structure.

This boils down to:

You should have %20 before the ? and + after.

With django 1.5 (at least) you can define the template you want to use for a particular modeladmin

see https://docs.djangoproject.com/en/1.5/ref/contrib/admin/#custom-template-options

You can do something like

class Myadmin(admin.ModelAdmin):
    change_form_template = 'change_form.htm'

With change_form.html being a simple html template extending admin/change_form.html (or not if you want to do it from scratch)

I want to write a program that (...) creates the directory and a (...) file inside of it

because this is a very common question, here is the code to create multiple levels of directories and than call fopen. I'm using a gnu extension to print the error message with printf.

void rek_mkdir(char *path) {
    char *sep = strrchr(path, '/');
    if(sep != NULL) {
        *sep = 0;
        rek_mkdir(path);
        *sep = '/';
    }
    if(mkdir(path, 0777) && errno != EEXIST)
        printf("error while trying to create '%s'\n%m\n", path); 
}

FILE *fopen_mkdir(char *path, char *mode) {
    char *sep = strrchr(path, '/');
    if(sep) { 
        char *path0 = strdup(path);
        path0[ sep - path ] = 0;
        rek_mkdir(path0);
        free(path0);
    }
    return fopen(path,mode);
}

The following example shows how to test the value of the IsPostBack property when the page is loaded in order to determine whether the page is being rendered for the first time or is responding to a postback. If the page is being rendered for the first time, the code calls the Page.Validate method. The page markup (not shown) contains RequiredFieldValidator controls that display asterisks if no entry is made for a required input field. Calling Page.Validate causes the asterisks to be displayed immediately when the page is rendered, instead of waiting until the user clicks the Submit button. After a postback, you do not have to call Page.Validate, because that method is called as part of the Page life cycle.

 private void Page_Load()
    {
        if (!IsPostBack)
        {      
        }
    }

There are two ways that I know of to color plot points by factor and then also have a corresponding legend automatically generated. I'll give examples of both:

1. Using ggplot2 (generally easier)
2. Using R's built in plotting functionality in combination with the colorRampPallete function (trickier, but many people prefer/need R's built-in plotting facilities)

For both examples, I will use the ggplot2 diamonds dataset. We'll be using the numeric columns diamond$carat and diamond$price, and the factor/categorical column diamond$color. You can load the dataset with the following code if you have ggplot2 installed:

library(ggplot2)
data(diamonds)

Using ggplot2 and qplot

It's a one liner. Key item here is to give qplot the factor you want to color by as the color argument. qplot will make a legend for you by default.

qplot(
  x = carat,
  y = price,
  data = diamonds,
  color = diamonds$color # color by factor color (I know, confusing)
)

Your output should look like this:

Using R's built in plot functionality

Using R's built in plot functionality to get a plot colored by a factor and an associated legend is a 4-step process, and it's a little more technical than using ggplot2.

First, we will make a colorRampPallete function. colorRampPallete() returns a new function that will generate a list of colors. In the snippet below, calling color_pallet_function(5) would return a list of 5 colors on a scale from red to orange to blue:

color_pallete_function <- colorRampPalette(
  colors = c("red", "orange", "blue"),
  space = "Lab" # Option used when colors do not represent a quantitative scale
  )

Second, we need to make a list of colors, with exactly one color per diamond color. This is the mapping we will use both to assign colors to individual plot points, and to create our legend.

num_colors <- nlevels(diamonds$color)
diamond_color_colors <- color_pallet_function(num_colors)

Third, we create our plot. This is done just like any other plot you've likely done, except we refer to the list of colors we made as our col argument. As long as we always use this same list, our mapping between colors and diamond$colors will be consistent across our R script.

plot(
  x = diamonds$carat,
  y = diamonds$price,
  xlab = "Carat",
  ylab = "Price",
  pch = 20, # solid dots increase the readability of this data plot
  col = diamond_color_colors[diamonds$color]
)

Fourth and finally, we add our legend so that someone reading our graph can clearly see the mapping between the plot point colors and the actual diamond colors.

legend(
  x ="topleft",
  legend = paste("Color", levels(diamonds$color)), # for readability of legend
  col = diamond_color_colors,
  pch = 19, # same as pch=20, just smaller
  cex = .7 # scale the legend to look attractively sized
)

Your output should look like this:

Nifty, right?

As far as I know a linter is included into the this package. And it requires you componend should begin from Capital character. Please check it.

However as for me it's sad.

Toggle function in react

At first you should create constructor like this

constructor(props) {
        super(props);
        this.state = {
            close: true,
        };
    }

Then create a function like this

yourFunction = () => {
        this.setState({
            close: !this.state.close,
        });
    };

then use this like

render() {
        const {close} = this.state;
        return (

            <Fragment>

                 <div onClick={() => this.yourFunction()}></div>

                 <div className={close ? "isYourDefaultClass" : "isYourOnChangeClass"}></div>

            </Fragment>
        )
    }
}

Please give better solutions

If the adapter is already set, setting it again will not refresh the listview. Instead first check if the listview has a adapter and then call the appropriate method.

I think its not a very good idea to create a new instance of the adapter while setting the list view. Instead, create an object.

BuildingAdapter adapter = new BuildingAdapter(context);

    if(getListView().getAdapter() == null){ //Adapter not set yet.
     setListAdapter(adapter);
    }
    else{ //Already has an adapter
    adapter.notifyDataSetChanged();
    }

Also you might try to run the refresh list on UI Thread:

activity.runOnUiThread(new Runnable() {         
        public void run() {
              //do your modifications here

              // for example    
              adapter.add(new Object());
              adapter.notifyDataSetChanged()  
        }
});

You don't have to bind parameters if you use query builder or eloquent ORM. However, if you use DB::raw(), ensure that you binding the parameters.

Try the following:

$array = array(1,2,3);       $query = DB::table('offers');             $query->select('id', 'business_id', 'address_id', 'title', 'details', 'value', 'total_available', 'start_date', 'end_date', 'terms', 'type', 'coupon_code', 'is_barcode_available', 'is_exclusive', 'userinformations_id', 'is_used');             $query->leftJoin('user_offer_collection', function ($join) use ($array)             {                 $join->on('user_offer_collection.offers_id', '=', 'offers.id')                       ->whereIn('user_offer_collection.user_id', $array);             });       $query->get();

At least in Visual Studio Ultimate 2013, Version 12.0.30723.00 Update 3, it's not possible to separate an if/else statement with a line break:

works:

if '$(BuildingInsideVisualStudio)' == 'true' (echo local) else (echo server)

doesn't work:

if '$(BuildingInsideVisualStudio)' == 'true' (echo local) 
else (echo server)

The way of dknaack does not work for me, I found this solution as well:

@Html.DropDownList("Chapters", ViewBag.Chapters as SelectList, 
                    "Select chapter", new { @onchange = "location = this.value;" })

where

@Html.DropDownList(controlName, ViewBag.property + cast, "Default value", @onchange event)

In the controller you can add:

DbModel db = new DbModel();    //entity model of Entity Framework

ViewBag.Chapters = new SelectList(db.T_Chapter, "Id", "Name");

Also, would I be right in concluding that a list comprehension is the most efficient way to do this?

Maybe. List comprehensions are not inherently computationally efficient. It is still running in linear time.

From my personal experience: I have significantly reduced computation time when dealing with large data sets by replacing list comprehensions (specifically nested ones) with for-loop/list-appending type structures you have above. In this application I doubt you will notice a difference.

In this case, to validate Date (DD-MM-YYYY) or (DD/MM/YYYY), with a year between 1900 and 2099,like this with month and Days validation

if (!Regex.Match(txtDob.Text, @"^(0[1-9]|1[0-9]|2[0-9]|3[0,1])([/+-])(0[1-9]|1[0-2])([/+-])(19|20)[0-9]{2}$").Success)                  
{
   MessageBox.Show("InValid Date of Birth");
   txtDob.Focus();
}

I found this worked for me.

$username = 'user'
$password = 'password'

$securePassword = ConvertTo-SecureString $password -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential $username, $securePassword

Updated: changed to using single quotes to avoid special character issues noted by Paddy.

Insert a dummy record into one of your databases that has a timestamp Select that record and get value of timestamp. Delete that record. Gets for sure the timezone that the server is using to write data and ignores PHP timezones.

I think you want to know the total entries count in a table! For that use this code..

SELECT count( * ) as Total_Entries FROM tbl_ifo;

You can query the USER_TAB_COLUMNS table for table column metadata.

SELECT table_name, column_name, data_type, data_length
FROM USER_TAB_COLUMNS
WHERE table_name = 'MYTABLE'

A datetime.timedelta corresponds to the difference between two dates, not a date itself. It's only expressed in terms of days, seconds, and microseconds, since larger time units like months and years don't decompose cleanly (is 30 days 1 month or 0.9677 months?).

If you want to convert a timedelta into hours and minutes, you can use the total_seconds() method to get the total number of seconds and then do some math:

x = datetime.timedelta(1, 5, 41038)  # Interval of 1 day and 5.41038 seconds
secs = x.total_seconds()
hours = int(secs / 3600)
minutes = int(secs / 60) % 60

There are several ways to do an email from HTML. Typically you see people doing a mailto like so:

<a href="mailto:[email protected]">Click to email</a>

But if you are doing it from a button you may want to look into a javascript solution.

There is nothing wrong with the idea of modifying an element inside a list while traversing it (don't modify the list itself, that's not recommended), but it can be better expressed like this:

for (int i = 0; i < letters.size(); i++) {
    letters.set(i, "D");
}

At the end the whole list will have the letter "D" as its content. It's not a good idea to use an enhanced for loop in this case, you're not using the iteration variable for anything, and besides you can't modify the list's contents using the iteration variable.

Notice that the above snippet is not modifying the list's structure - meaning: no elements are added or removed and the lists' size remains constant. Simply replacing one element by another doesn't count as a structural modification. Here's the link to the documentation quoted by @ZouZou in the comments, it states that:

A structural modification is any operation that adds or deletes one or more elements, or explicitly resizes the backing array; merely setting the value of an element is not a structural modification

Replace this line:

count(if(ccc_news_comments.id = 'approved', ccc_news_comments.id, 0)) AS comments

With this one:

coalesce(sum(ccc_news_comments.id = 'approved'), 0) comments

Simply you can create a function in a js file and export it for usages in components

like below:

export default function setTitle(title) {
  if (typeof title !== "string") {
     throw new Error("Title should be an string");
  }
  document.title = title;
}

and use it in any component like this:

import React, { Component } from 'react';
import setTitle from './setTitle.js' // no need to js extension at the end

class App extends Component {
  componentDidMount() {
    setTitle("i am a new title");
  }

  render() {
    return (
      <div>
        see the title
      </div>
    );
  }
}

export default App

$('#divId > input, #divId > select, #divId > textarea').serialize();

You can use awk just to print the first 'field' if there won't be any spaces (or if there will be, change the separator'.

I put the fields you had above into a file and did this

awk '{ print $1 }' < test.txt 
1234567890
1234567891

I don't know if that's any better.

XSLT 2

Date functions are available natively, such as:

<xsl:value-of  select="current-dateTime()"/>

There is also current-date() and current-time().

XSLT 1

Use the EXSLT date and times extension package.

1. Download the date and times package from GitHub.
2. Extract date.xsl to the location of your XSL files.
3. Set the stylesheet header.
4. Import date.xsl.

For example:

<xsl:stylesheet version="1.0" 
    xmlns:date="http://exslt.org/dates-and-times" 
    extension-element-prefixes="date"
    ...>

    <xsl:import href="date.xsl" />

    <xsl:template match="//root">
       <xsl:value-of select="date:date-time()"/>
    </xsl:template>
</xsl:stylesheet>

That is because you are opening , writing and closing the file 10 times inside your for loop

myfile = open('xyz.txt', 'w')
myfile.writelines(var1)
myfile.close()

You should open and close your file outside for loop.

myfile = open('xyz.txt', 'w')
for line in lines:
    var1, var2 = line.split(",");
    myfile.write("%s\n" % var1)

myfile.close()
text_file.close()

You should also notice to use write and not writelines.

writelines writes a list of lines to your file.

Also you should check out the answers posted by folks here that uses with statement. That is the elegant way to do file read/write operations in Python

You need to consider your objectives:

1) Are you trying to prevent people from reading/modifying your code? If yes, you'll need an obfuscation/encryption tool. I've used Zend Guard with good success.

2) Are you trying to prevent unauthorized redistribution of your code?? A EULA/proprietary license will give you the legal power to prevent that, but won't actually stop it. An key/activation scheme will allow you to actively monitor usage, but can be removed unless you also encrypt your code. Zend Guard also has capabilities to lock a particular script to a particular customer machine and/or create time limited versions of the code if that's what you want to do.

I'm not familiar with vBulletin and the like, but they'd either need to encrypt/obfuscate or trust their users to do the right thing. In the latter case they have the protection of having a EULA which prohibits the behaviors they find undesirable, and the legal system to back up breaches of the EULA.

If you're not prepared/able to take legal action to protect your software and you don't want to encrypt/obfuscate, your options are a) Release it with a EULA so you're have a legal option if you ever need it and hope for the best, or b) consider whether an open source license might be more appropriate and just allow redistribution.

This problem can also arise if you include jQuery more than once.

Used this to convert any String number to double when u need int just convert the data type from num and num2 to int ; took all the cases for any string double with Eng:"Bader Qandeel"

public static double str2doubel(String str) {
    double num = 0;
    double num2 = 0;
    int idForDot = str.indexOf('.');
    boolean isNeg = false;
    String st;
    int start = 0;
    int end = str.length();

    if (idForDot != -1) {
        st = str.substring(0, idForDot);
        for (int i = str.length() - 1; i >= idForDot + 1; i--) {
            num2 = (num2 + str.charAt(i) - '0') / 10;
        }
    } else {
        st = str;
    }

    if (st.charAt(0) == '-') {
        isNeg = true;
        start++;
    } else if (st.charAt(0) == '+') {
        start++;
    }

    for (int i = start; i < st.length(); i++) {
        if (st.charAt(i) == ',') {
            continue;
        }
        num *= 10;
        num += st.charAt(i) - '0';
    }

    num = num + num2;
    if (isNeg) {
        num = -1 * num;
    }
    return num;
}

I tried the solutions above and it looks like on rails 5.* the second agument by default is the value of the input form, what worked for me was:

text_field_tag :attr, "", placeholder: "placeholder text"

You need to add the column with a default of null, then alter the column to have default now().

ALTER TABLE mytable ADD COLUMN created_at TIMESTAMP;
ALTER TABLE mytable ALTER COLUMN created_at SET DEFAULT now();

Just to notify here. (from a newbee, keviv22)

Never and ever for the sake of your own good, name the folders or files with symbols like "-" or "_". If you did so, you may face few issues. like mine, say, though your command for importing is correct, you wont be able to successfully import the desired files which are available inside such named folders.

Invalid Folder namings as follows:

• Generic-Classes-Folder
• Generic_Classes_Folder

valid Folder namings for above:

• GenericClassesFolder or Genericclassesfolder or genericClassesFolder (or like this without any spaces or special symbols among the words)

What mistake I did:

consider the file structure.

Parent
   . __init__.py
   . Setup
     .. __init__.py
     .. Generic-Class-Folder
        ... __init__.py
        ... targetClass.py
   . Check
     .. __init__.py
     .. testFile.py

What I wanted to do?

• from testFile.py, I wanted to import the 'targetClass.py' file inside the Generic-Class-Folder file to use the function named "functionExecute" in 'targetClass.py' file

What command I did?

• from 'testFile.py', wrote command, from Core.Generic-Class-Folder.targetClass import functionExecute
• Got errors like SyntaxError: invalid syntax

Tried many searches and viewed many stackoverflow questions and unable to decide what went wrong. I cross checked my files multiple times, i used __init__.py file, inserted environment path and hugely worried what went wrong......

And after a long long long time, i figured this out while talking with a friend of mine. I am little stupid to use such naming conventions. I should never use space or special symbols to define a name for any folder or file. So, this is what I wanted to convey. Have a good day!

(sorry for the huge post over this... just letting my frustrations go.... :) Thanks!)

Add -lm to your link options, since pow() and floor() are part of the math library:

gcc fib.c -o fibo -lm

I think its a bug in android..It can be fixed by adding this patch :)
Check these links question 1 and question 2

Hope it will be useful.

Try including stdint.h or inttypes.h.

In my case, there was no string on which i was calling appendChild, the object i was passing on appendChild argument was wrong, it was an array and i had pass an element object, so i used divel.appendChild(childel[0]) instead of divel.appendChild(childel) and it worked. Hope it help someone.

The --force option will reinstall already installed packages or overwrite already installed files from other packages. You don't want this normally.

If you tell rpm to install all RPMs from some directory, then it does exactly this. rpm will not ignore RPMs listed for installation. You must manually remove the unneeded RPMs from the list (or directory). It will always overwrite the files with the "latest RPM installed" whichever order you do it in.

You can remove the old RPM and rpm will resolve the dependency with the newer version of the installed RPM. But this will only work, if none of the to be installed RPMs depends exactly on the old version.

If you really need different versions of the same RPM, then the RPM must be relocatable. You can then tell rpm to install the specific RPM to a different directory. If the files are not conflicting, then you can just install different versions with rpm -i (zypper in can not install different versions of the same RPM). I am packaging for example ruby gems as relocatable RPMs at work. So I can have different versions of the same gem installed.

I don't know on which files your RPMs are conflicting, but if all of them are "just" man pages, then you probably can simply overwrite the new ones with the old ones with rpm -i --replacefiles. The only problem with this would be, that it could confuse somebody who is reading the old man page and thinks it is for the actual version. Another problem would be the rpm --verify command. It will complain for the new package if the old one has overwritten some files.

Is this possibly a duplicate of https://serverfault.com/questions/522525/rpm-ignore-conflicts?

From Prepared statements and stored procedures

Use bindParam to insert multiple rows with one time binding:

<?php

$stmt = $dbh->prepare("INSERT INTO REGISTRY (name, value) VALUES (?, ?)");
$stmt->bindParam(1, $name);
$stmt->bindParam(2, $value);

// insert one row
$name = 'one';
$value = 1;
$stmt->execute();

// insert another row with different values
$name = 'two';
$value = 2;
$stmt->execute();

In the case you need to manually 'exit' a transaction through code (be it through an exception or simply checking an error state) you shouldn't use DB::transaction() but instead wrap your code in DB::beginTransaction and DB::commit/DB::rollback():

DB::beginTransaction();

try {
    DB::insert(...);
    DB::insert(...);
    DB::insert(...);

    DB::commit();
    // all good
} catch (\Exception $e) {
    DB::rollback();
    // something went wrong
}

See the transaction docs.

Solution --> npm start then open new Terminal and go to your project path and then hit react-native run-ios it works for me

Since you mention you have a proxy connection I will tell you what worked for me: I went to properties (as friedrich mentioned) ensuring the Offline Work was unchecked. I opened up the gradle.properties file in the IDE and added my proxy settings. Here's a generic version:

systemProp.http.proxyHost=www.somehost.org
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=userid
systemProp.http.proxyPassword=password
systemProp.http.nonProxyHosts=*.nonproxyrepos.com|localhost

Then at the top of the properties file in the IDE there was a "Try Again" link which I clicked. That did it.

I am seeing starkly different runtimes when I take a for loop in g++ 4.7.0 and using

std::vector<double> x;
std::vector<double> y;
std::vector<double> prod;

for (int i = 0; i < 5000000; i++)
{
   double r1 = ((double)rand() / double(RAND_MAX)) * 5;
   double r2 = ((double)rand() / double(RAND_MAX)) * 5;
   x.push_back(r1);
   y.push_back(r2);
}

int sz = x.size();

#pragma omp parallel for

for (int i = 0; i< sz; i++)
   prod[i] = x[i] * y[i];

the serial code (no openmp ) runs in 79 ms. the "parallel for" code runs in 29 ms. If I omit the for and use #pragma omp parallel, the runtime shoots up to 179ms, which is slower than serial code. (the machine has hw concurrency of 8)

the code links to libgomp

All “insensitive”s are boldened for readability.

Domain names are case insensitive according to RFC 4343. The rest of URL is sent to the server via the GET method. This may be case sensitive or not.

Take this page for example, stackoverflow.com receives GET string /questions/7996919/should-url-be-case-sensitive, sending a HTML document to your browser. Stackoverflow.com is case insensitive because it produces the same result for /QUEStions/7996919/Should-url-be-case-sensitive.

On the other hand, Wikipedia is case sensitive except the first character of the title. The URLs https://en.wikipedia.org/wiki/Case_sensitivity and https://en.wikipedia.org/wiki/case_sensitivity leads to the same article, but https://en.wikipedia.org/wiki/CASE_SENSITIVITY returns 404.

I would imagine the safest way would just be to parse for <>s, no? Loop through the entire string, and copy anything not enclosed in <>s to a new string.

To put it roughly, you're dealing with node.js which is asynchronous in nature.

When we talk about async, we're talking about doing or processing info or data while dealing with something else. It is not synonymous to parallel, please be reminded.

Your code:

var content;
fs.readFile('./Index.html', function read(err, data) {
    if (err) {
        throw err;
    }
    content = data;
});
console.log(content);

With your sample, it basically does the console.log part first, thus the variable 'content' being undefined.

If you really want the output, do something like this instead:

var content;
fs.readFile('./Index.html', function read(err, data) {
    if (err) {
        throw err;
    }
    content = data;
    console.log(content);
});

This is asynchronous. It will be hard to get used to but, it is what it is. Again, this is a rough but fast explanation of what async is.

For extending control functionality like this, I like to use extension methods so that it can be reused easily. Here is a starter extensions file that contains an extension to disable sorting on a datagridview.

To use it, just include it in your project and call like this

myDatagridView.DisableSorting()

In my case, I added this line of code in the DataBindingComplete eventhandler of the DataGridView where I wanted sorting disabled

Imports System.ComponentModel
Imports System.Reflection
Imports System.Runtime.CompilerServices
Imports System.Windows.Forms

Public Module Extensions

<Extension()>
Public Sub DisableSorting(datagrid As DataGridView)
    For index = 0 To datagrid.Columns.Count - 1
        datagrid.Columns(index).SortMode = DataGridViewColumnSortMode.NotSortable
    Next
End Sub


End Module

Escaping apostrophes and quotes

If you have an apostrophe or a quote in your string, you must either escape it or enclose the whole string in the other type of enclosing quotes. For example, here are some stings that do and don't work:

<string name="good_example">"This'll work"</string>
<string name="good_example_2">This\'ll also work</string>
<string name="bad_example">This doesn't work</string>
<string name="bad_example_2">XML encodings don&apos;t work</string>

To go off of Thapa's answer, you need to cast to the viewcontroller class before using...

   if let wd = self.view.window {
        var vc = wd.rootViewController!
        if(vc is UINavigationController){
            vc = (vc as! UINavigationController).visibleViewController
        }
        if(vc is customViewController){
            var viewController : customViewController = vc as! customViewController

Another solution to get rid of content jump on fixed modal, when removing body scroll is to normalize page width:

body {width: 100vw; overflow-x: hidden;}

Then you can play with fixed position or overflow:hidden for body when the modal is open. But it will hide horizontal scrollbars - usually they're not needed on responsive website.

Similar to Orland's answer here: https://stackoverflow.com/a/32870380/462781

Combined with Chris' code here: https://stackoverflow.com/a/12121309/462781

You can use a margin in %. Additionally "space" images can be placed next to each other inside a 3rd level div.

simple synchronous way with node:

let fs = require('fs')

let filename = "your-file.something"

let content = fs.readFileSync(process.cwd() + "/" + filename).toString()

console.log(content)

(I presume that you've concluded that it's an iptables problem by dropping the firewall completely (iptables -P INPUT ACCEPT; iptables -P OUTPUT ACCEPT; iptables -F) and confirmed that you can connect to the MySQL server from your Windows box?)

Some previous rule in the INPUT table is probably rejecting or dropping the packet. You can get around that by inserting the new rule at the top, although you might want to review your existing rules to see whether that's sensible:

iptables -I INPUT 1 -p tcp --dport 3306 -j ACCEPT

Note that iptables-save won't save the new rule persistently (i.e. across reboots) - you'll need to figure out something else for that. My usual route is to store the iptables-save output in a file (/etc/network/iptables.rules or similar) and then load then with a pre-up statement in /etc/network/interfaces).

I you have the char '9', it will store its ASCII code, so to get the int value, you have 2 ways

char x = '9';
int y = Character.getNumericValue(x);   //use a existing function
System.out.println(y + " " + (y + 1));  // 9  10

or

char x = '9';
int y = x - '0';                        // substract '0' code to get the difference
System.out.println(y + " " + (y + 1));  // 9  10

And it fact, this works also :

char x = 9;
System.out.println(">" + x + "<");     //>  < prints a horizontal tab
int y = (int) x;
System.out.println(y + " " + (y + 1)); //9 10

You store the 9 code, which corresponds to a horizontal tab (you can see when print as String, bu you can also use it as int as you see above

Starting from C# 6.0, when $ - string interpolation has been introduced, there is one more way:

var array = new[] { "A", "B", "C" };
Console.WriteLine($"{string.Join(", ", array}");

//output
A, B, C

Concatenation could be archived using the System.Linq, convert the string[] to char[] and print as a string

var array = new[] { "A", "B", "C" };
Console.WriteLine($"{new String(array.SelectMany(_ => _).ToArray())}");

//output
ABC

For PostgreSQL... It didn't work for me with index; it gave me an error, so I did this:

alter table table_name
add unique(column_name_1,column_name_2);

PostgreSQL gave unique index its own name. I guess you can change the name of index in the options for the table, if it is needed to be changed...

I know this basic method:

1)

<input type=”image” src=”submit.png”> (in any place)

2)

<form name=”print”>
<input type=”hidden” name=”a” value=”<?= $a ?>”>
<input type=”hidden” name=”b” value=”<?= $b ?>”>
<input type=”hidden” name=”c” value=”<?= $c ?>”>
</form>

3)

<script>
$(‘#submit’).click(function(){
    open(”,”results”);
    with(document.print)
    {
        method = “POST”;
        action = “results.php”;
        target = “results”;
        submit();
    }
});
</script>

Works!

Generally speaking, 5xx response codes indicate non-programmatic failures, such as a database connection failure, or some other system/library dependency failure. In many cases, it is expected that the client can re-submit the same request in the future and expect it to be successful.

Yes, some web-frameworks will respond with 5xx codes, but those are typically the result of defects in the code and the framework is too abstract to know what happened, so it defaults to this type of response; that example, however, doesn't mean that we should be in the habit of returning 5xx codes as the result of programmatic behavior that is unrelated to out of process systems. There are many, well defined response codes that are more suitable than the 5xx codes. Being unable to parse/validate a given input is not a 5xx response because the code can accommodate a more suitable response that won't leave the client thinking that they can resubmit the same request, when in fact, they can not.

To be clear, if the error encountered by the server was due to CLIENT input, then this is clearly a CLIENT error and should be handled with a 4xx response code. The expectation is that the client will correct the error in their request and resubmit.

It is completely acceptable, however, to catch any out of process errors and interpret them as a 5xx response, but be aware that you should also include further information in the response to indicate exactly what failed; and even better if you can include SLA times to address.

I don't think it's a good practice to interpret, "an unexpected error" as a 5xx error because bugs happen.

It is a common alert monitor to begin alerting on 5xx types of errors because these typically indicate failed systems, rather than failed code. So, code accordingly!

Your code can be factored to this (in lieu of File.ReadAllBytes):

public byte[] ReadAllBytes(string fileName)
{
    byte[] buffer = null;
    using (FileStream fs = new FileStream(fileName, FileMode.Open, FileAccess.Read))
    {
        buffer = new byte[fs.Length];
        fs.Read(buffer, 0, (int)fs.Length);
    }
    return buffer;
} 

Note the Integer.MaxValue - file size limitation placed by the Read method. In other words you can only read a 2GB chunk at once.

Also note that the last argument to the FileStream is a buffer size.

I would also suggest reading about FileStream and BufferedStream.

As always a simple sample program to profile which is fastest will be most beneficial.

Also your underlying hardware will have a large effect on performance. Are you using server based hard disk drives with large caches and a RAID card with onboard memory cache? Or are you using a standard drive connected to the IDE port?

Fur future readers, if you are using Angular 1.6, you also need to change the hashPrefix:

appModule.config(['$locationProvider', function($locationProvider) {
    $locationProvider.html5Mode(true);
    $locationProvider.hashPrefix('');
}]);

Don't forget to set the base in your HTML <head>:

<head>
    <base href="/">
    ...
</head>

Just a comment on this, when using material design lite, jquery selector does not return the property for material design for some reason.

For:

<div class="logonfield mdl-textfield mdl-js-textfield mdl-textfield--floating-label">
        <input class="mdl-textfield__input" type="text" id="myinputfield" required>
        <label class="mdl-textfield__label" for="myinputfield">Enter something..</label>
      </div>

This works:

document.querySelector('#myinputfield').parentNode.MaterialTextfield.change();

This does not:

$('#myinputfield').parentNode.MaterialTextfield.change();

Because the second element is null after you clear the list.

Use:

String s = myList.get(0);

And remember, index 0 is the first element.

If you are using localhost in your url and testing your application in emulator , simply you can replace system's ip address for localhost in the URL.or you can use 10.0.2.2 instead of localhost.

http://localhost/webservice.php to http://10.218.28.19/webservice.php

Where 10.218.28.19 -> System's IP Address.

or

http://localhost/webservice.php to http://10.0.2.2/webservice.php

if the id of the radio buttons are 'male' and 'female', value reset can be done by using jquery

$('input[id=male]').attr('checked',false);
$('input[id=female]').attr('checked',false);

In addition, since info locals does not display the arguments to the function you're in, use

(gdb) info args

For example:

int main(int argc, char *argv[]) {
    argc = 6*7;    //Break here.
    return 0;
}

argc and argv won't be shown by info locals. The message will be "No locals."

Reference: info locals command.

Also, try to use 'pgrep' command instead of 'ps -A | grep 'process_name'

I moved the tsconfig.json file into a new folder to restructure my project.

So it wasn't able to resolve the path to node_modules/@types folder inside typeRoots property of tsconfig.json

So just update the path from

"typeRoots": [
  "../node_modules/@types"
]

to

"typeRoots": [
  "../../node_modules/@types"
]

To just ensure that the path to node_modules is resolved from the new location of the tsconfig.json

In practice, the most common reason for this happening seems to be that the .rnd file in your home directory is owned by root rather than your account. The quick fix:

sudo rm ~/.rnd

For more information, here's the entry from the OpenSSL FAQ:

Sometimes the openssl command line utility does not abort with a "PRNG not seeded" error message, but complains that it is "unable to write 'random state'". This message refers to the default seeding file (see previous answer). A possible reason is that no default filename is known because neither RANDFILE nor HOME is set. (Versions up to 0.9.6 used file ".rnd" in the current directory in this case, but this has changed with 0.9.6a.)

So I would check RANDFILE, HOME, and permissions to write to those places in the filesystem.

If everything seems to be in order, you could try running with strace and see what exactly is going on.

I keep hitting this as a top link for google "ruby for loop", so I wanted to add a solution for loops where the step wasn't simply '1'. For these cases, you can use the 'step' method that exists on Numerics and Date objects. I think this is a close approximation for a 'for' loop.

start = Date.new(2013,06,30)
stop = Date.new(2011,06,30)
# step back in time over two years, one week at a time
start.step(stop, -7).each do |d| 
    puts d
end

The Java code given by Dommer above gives slightly incorrect results but the small errors add up if you are processing say a GPS track. Here is an implementation of the Haversine method in Java which also takes into account height differences between two points.

/**
 * Calculate distance between two points in latitude and longitude taking
 * into account height difference. If you are not interested in height
 * difference pass 0.0. Uses Haversine method as its base.
 * 
 * lat1, lon1 Start point lat2, lon2 End point el1 Start altitude in meters
 * el2 End altitude in meters
 * @returns Distance in Meters
 */
public static double distance(double lat1, double lat2, double lon1,
        double lon2, double el1, double el2) {

    final int R = 6371; // Radius of the earth

    double latDistance = Math.toRadians(lat2 - lat1);
    double lonDistance = Math.toRadians(lon2 - lon1);
    double a = Math.sin(latDistance / 2) * Math.sin(latDistance / 2)
            + Math.cos(Math.toRadians(lat1)) * Math.cos(Math.toRadians(lat2))
            * Math.sin(lonDistance / 2) * Math.sin(lonDistance / 2);
    double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));
    double distance = R * c * 1000; // convert to meters

    double height = el1 - el2;

    distance = Math.pow(distance, 2) + Math.pow(height, 2);

    return Math.sqrt(distance);
}

We do not need to use recursive method, it may be slow. My solution is using a user-defined function rint instesd of instrinsic function int or floor.

rint(x)=(x-int(x)>0.9999)?int(x)+1:int(x)

This function will give rint(0.0003/0.0001)=3, while int(0.0003/0.0001)=floor(0.0003/0.0001)=2.

Why? Please look at Perl int function and padding zeros

Here is some SQL that actually make sense:

SELECT m.id FROM match m LEFT JOIN email e ON e.id = m.id WHERE e.id IS NULL

Simple is always better.

I would be inclined to include the year in the output. One way:

select to_char(DATE_CREATED, 'YYYY-MM'), sum(Num_of_Pictures)
from pictures_table
group by to_char(DATE_CREATED, 'YYYY-MM')
order by 1

Another way (more standard SQL):

select extract(year from date_created) as yr, extract(month from date_created) as mon,
       sum(Num_of_Pictures)
from pictures_table
group by extract(year from date_created), extract(month from date_created)
order by yr, mon;

Remember the order by, since you presumably want these in order, and there is no guarantee about the order that rows are returned in after a group by.

You can use the cache dir using context.getCacheDir().

File temp=File.createTempFile("prefix","suffix",context.getCacheDir());

Hie,

Although late If anybody suffering from the similar issues here is what you can do to allow permalinks by modifying your virtual host file or whereever you are hosting your WP sites.

So basically everything works fine - you set up permalinks to post and suddenly the url dissapears. You went to a lot of disscussion forums (Like me) tried a lot of modifying and got "Permission to server 403" errors or URL not found error. All you have to do is go to the host file, for example 000-default.conf if using a default virtual host or your config file inside sites-enabled,

use in the directory section :

<Directory "path/to/dir">
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>

Donot use the following inside directory

Order allow,deny
Allow from all

The Order and Allow directives are deprecated in Apache 2.4.

Likewise you can setup the directory in /etc/apache2/apache2.conf set the directory for your path and donot use the above - this will cause permission 403 error.

In addition to that you will need to enable mod_rewrite for apache

In my case, it started hapenning after I updated to Android Studio 1.2. To fix it I just had to remove "\bin" from my JAVA_HOME variable.

You should be able to accomplish this by adding a refspec for tags to your local config. Concretely:

[remote "upstream"]
    url = <redacted>
    fetch = +refs/heads/*:refs/remotes/upstream/*
    fetch = +refs/tags/*:refs/tags/*

Select Case parameter 
    Case "userID"
        ' does something here.
    Case "packageID"
        ' does something here.
    Case "mvrType" 
        If otherFactor Then 
            ' does something here.
        End If 
    Case Else 
        ' does some processing... 
        Exit Select 
End Select

Is there a reason for the goto? If it doesn't meet the if criterion, it will simply not perform the function and go to the next case.

Is there any reason not to use threads? You can use the threading class. Instead of finished() function use the isAlive(). The result() function could join() the thread and retrieve the result. And, if you can, override the run() and __init__ functions to call the function specified in the constructor and save the value somewhere to the instance of the class.

Follow these steps

1. Add cors dependency. type the following in cli inside your project directory

npm install --save cors

2. Include the module inside your project

var cors = require('cors');

3. Finally use it as a middleware.

app.use(cors());

If you're not against using an external dependency from maven central, I wrote gethostname4j to solve this problem for myself. It just uses JNA to call libc's gethostname function (or gets the ComputerName on Windows) and returns it to you as a string.

https://github.com/mattsheppard/gethostname4j

You can also use callto:########### replacing the email code mail with call, at least according to W3Cschool site but I haven't had an opportunity to test it out.

If you are planning to use appending more then once, you might want to write a function:

//Append text to input element
function jQ_append(id_of_input, text){
    var input_id = '#'+id_of_input;
    $(input_id).val($(input_id).val() + text);
}

After you can just call it:

jQ_append('my_input_id', 'add this text');
