I was facing this problem when trying to add a .NETStandard dependency to a .NET4.6.1 library, and compiling it in Linux with Mono 4.6.2 (the version that comes with Ubuntu 16.04).
I finally solved it today; the solution requires to do both of these things:
<TargetFrameworkVersion>v4.6.1</TargetFrameworkVersion>
to <TargetFrameworkVersion>v4.7.1</TargetFrameworkVersion>
in the .csproj file.To fix this problem on specific page need to set some validation settings when page loading. Write code below in Page_Load()
method:
protected void Page_Load(object sender, EventArgs e)
{
ValidationSettings.UnobtrusiveValidationMode = UnobtrusiveValidationMode.None;
}
Its work for me in .NET 4.5
Things to check when enabling the bundle optimization;
BundleTable.EnableOptimizations = true;
and
webconfig debug = "false"
bundles.IgnoreList.Clear();
this will ignore the minified assets of your bundles like *.min.css
or *.min.js
which can cause an undefine error of your script. To fix is replace the .min
asset to original. if you do this you may not need the bundles.IgnoreList.Clear();
e.g.
bundles.Add(new ScriptBundle("~/bundles/datatablesjs")
.Include("~/Scripts/datatables.min.js") <---- change this to non minified ver.
Make sure the names of the bundles of your css and js are unique.
bundles.Add(new StyleBundle("~/bundles/datatablescss").Include( ...) );
bundles.Add(new ScriptBundle("~/bundles/datatablesjs").Include( ...) );
Make sure you use the Render name of your @Script.Render and Style.Render are the same on your bundle config. e.g.
@Styles.Render("~/bundles/datatablescss")
@Scripts.Render("~/bundles/datatablesjs")
You need the Microsoft.AspNet.WebApi.Core package.
You can see it in the .csproj file:
<Reference Include="System.Web.Http, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
<SpecificVersion>False</SpecificVersion>
<HintPath>..\packages\Microsoft.AspNet.WebApi.Core.5.0.0\lib\net45\System.Web.Http.dll</HintPath>

Try it this way, I just made some light changes:
MailMessage msg = new MailMessage();
msg.From = new MailAddress("[email protected]");
msg.To.Add("[email protected]");
msg.Subject = "test";
msg.Body = "Test Content";
//msg.Priority = MailPriority.High;
using (SmtpClient client = new SmtpClient())
{
client.EnableSsl = true;
client.UseDefaultCredentials = false;
client.Credentials = new NetworkCredential("[email protected]", "mypassword");
client.Host = "smtp.gmail.com";
client.Port = 587;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.Send(msg);
}
Also please show your app.config file, if you have mail settings there.
I think the problem is from this line:
<context type="GdpSoftware.Server.Data.GdpSoftwareDbContext, GdpSoftware.Server.Data" disableDatabaseInitialization="true">
I don't know why you are using this approach and how it works...
Maybe it's better to try to get it out from web.config and go another way
[Required(ErrorMessage = "Please enter Social Email id")]
[DataType(DataType.EmailAddress)]
[EmailAddress]
public string Email { get; set; }
You need a web.config key to enable the pre 4.5 validation mode.
More Info on ValidationSettings:UnobtrusiveValidationMode:
Specifies how ASP.NET globally enables the built-in validator controls to use unobtrusive JavaScript for client-side validation logic.
Type: UnobtrusiveValidationMode
Default value: None
Remarks: If this key value is set to "None" [default], the ASP.NET application will use the pre-4.5 behavior (JavaScript inline in the pages) for client-side validation logic. If this key value is set to "WebForms", ASP.NET uses HTML5 data-attributes and late bound JavaScript from an added script reference for client-side validation logic.
Example:
<appSettings> <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" /> </appSettings>
the line below shows you haven't set an DataAttribute like required on AgreementNumber
<input id="AgreementNumber" name="AgreementNumber" size="30" type="text" value="387893" />
you need
[Required]
public String AgreementNumber{get;set;}
You can do it this way:
(Edit: Considering that you're waiting for a response json
with dataType: 'json'
)
.NET
public JsonResult Edit(EditPostViewModel data)
{
if(ModelState.IsValid)
{
// Save
return Json(new { Ok = true } );
}
return Json(new { Ok = false } );
}
JS:
success: function (data) {
if (data.Ok) {
alert('success');
}
else {
alert('problem');
}
},
If you need I can also explain how to do it by returning a error 500, and get the error in the event error (ajax). But in your case this may be an option

If you're using LESS/SASS CSS transformation there's an option useNativeMinification
which can be set to false to disable minification (in web.config). For my purposes I just change it here when I need to, but you could use web.config transformations to always enable it on release build or perhaps find a way modify it in code.
<less useNativeMinification="false" ieCompat="true" strictMath="false"
strictUnits="false" dumpLineNumbers="None">
Tip: The whole point of this is to view your CSS, which you can do in the browser inspect tools or by just opening the file. When bundling is enabled that filename changes on every compile so I put the following at the top of my page so I can view my compiled CSS eaily in a new browser window every time it changes.
@if (Debugger.IsAttached)
{
<a href="@Styles.Url(ViewBag.CSS)" target="css">View CSS</a>
}
this will be a dynamic URL something like https://example.com/Content/css/bundlename?v=UGd0FjvFJz3ETxlNN9NVqNOeYMRrOkQAkYtB04KisCQ1
Update: I created a web.config transformation to set it to true for me during deployment / release build
<bundleTransformer xmlns="http://tempuri.org/BundleTransformer.Configuration.xsd">
<less xdt:Transform="Replace" useNativeMinification="true" ieCompat="true" strictMath="false" strictUnits="false" dumpLineNumbers="None">
<jsEngine name="MsieJsEngine" />
</less>
</bundleTransformer>
With the unobtrusive way:
Jquery Validate Example:
<input type="text" name="email" class="required">
<script>
$(function () {
$("form").validate();
});
</script>
Jquery Validate Unobtrusive Example:
<input type="text" name="email" data-val="true"
data-val-required="This field is required.">
<div class="validation-summary-valid" data-valmsg-summary="true">
<ul><li style="display:none"></li></ul>
</div>
View and check the reference paths in your csproj.
I had removed references to System.Web.Mvc (and others) and readded them to a custom path. C:\Project\OurWebReferences
However, after doing this, the reference path in the still csproj did not change. WAS
<Reference Include="System.Web.Mvc, Version=4.0.0.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
<SpecificVersion>False</SpecificVersion>
<HintPath>..\..\..\..\OurWebProject\bin\Debug\System.Web.Mvc.dll</HintPath>
</Reference>
Changed to manually
<Reference Include="System.Web.Mvc, Version=4.0.0.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
<SpecificVersion>False</SpecificVersion>
<HintPath>..\..\..\..\OurWebReferences\System.Web.Mvc.dll</HintPath>
</Reference>
Paths are an example only.
I also ran into this problem. I solved the problem by going to the Application Pools > Application Pool Name and changed the .NET Framework from version v.2.0.50727 to v4.0.30319.
Try using the ASCII code for those values:
^([a-zA-Z0-9 .\x26\x27-]+)$
\x26
= &
\x27
= '
The format is \xnn
where nn is the two-digit hexadecimal character code. You could also use \unnnn
to specify a four-digit hex character code for the Unicode character.
Oh ok - now I get it. You can ignore this one - the XML for this is just not correct - the packages-element is indeed not declared (there is no reference to a schema or whatever). I think this is a known minor bug that won't do a thing because only NuGet will use this.

Updated for 2014: You don't need jQuery for this. You can fully style a select box without jQuery using StyleSelect. Eg, given the following select box:
<select class="demo">
<option value="value1">Label 1</option>
<option value="value2" selected>Label 2</option>
<option value="value3">Label 3</option>
</select>
Running styleSelect('select.demo')
would create a styled select box as follows:
Try this JavaScript code:
function printout() {
var newWindow = window.open();
newWindow.document.write(document.getElementById("output").innerHTML);
newWindow.print();
}
You should have a look at the scalax library : http://scalax.scalaforge.org/ In this library, there is a Logging trait, using sl4j as backend. By using this trait, you can log quite easily (just use the logger field in the class inheriting the trait).

You can host one yourself since it is open source. The code is on github.
Just for completeness: Xlib - But it's somewhat slow when capturing the whole screen:
from Xlib import display, X
import Image #PIL
W,H = 200,200
dsp = display.Display()
try:
root = dsp.screen().root
raw = root.get_image(0, 0, W,H, X.ZPixmap, 0xffffffff)
image = Image.fromstring("RGB", (W, H), raw.data, "raw", "BGRX")
image.show()
finally:
dsp.close()
One could try to trow some types in the bottleneck-files in PyXlib, and then compile it using Cython. That could increase the speed a bit.
Edit: We can write the core of the function in C, and then use it in python from ctypes, here is something I hacked together:
#include <stdio.h>
#include <X11/X.h>
#include <X11/Xlib.h>
//Compile hint: gcc -shared -O3 -lX11 -fPIC -Wl,-soname,prtscn -o prtscn.so prtscn.c
void getScreen(const int, const int, const int, const int, unsigned char *);
void getScreen(const int xx,const int yy,const int W, const int H, /*out*/ unsigned char * data)
{
Display *display = XOpenDisplay(NULL);
Window root = DefaultRootWindow(display);
XImage *image = XGetImage(display,root, xx,yy, W,H, AllPlanes, ZPixmap);
unsigned long red_mask = image->red_mask;
unsigned long green_mask = image->green_mask;
unsigned long blue_mask = image->blue_mask;
int x, y;
int ii = 0;
for (y = 0; y < H; y++) {
for (x = 0; x < W; x++) {
unsigned long pixel = XGetPixel(image,x,y);
unsigned char blue = (pixel & blue_mask);
unsigned char green = (pixel & green_mask) >> 8;
unsigned char red = (pixel & red_mask) >> 16;
data[ii + 2] = blue;
data[ii + 1] = green;
data[ii + 0] = red;
ii += 3;
}
}
XDestroyImage(image);
XDestroyWindow(display, root);
XCloseDisplay(display);
}
And then the python-file:
import ctypes
import os
from PIL import Image
LibName = 'prtscn.so'
AbsLibPath = os.path.dirname(os.path.abspath(__file__)) + os.path.sep + LibName
grab = ctypes.CDLL(AbsLibPath)
def grab_screen(x1,y1,x2,y2):
w, h = x2-x1, y2-y1
size = w * h
objlength = size * 3
grab.getScreen.argtypes = []
result = (ctypes.c_ubyte*objlength)()
grab.getScreen(x1,y1, w, h, result)
return Image.frombuffer('RGB', (w, h), result, 'raw', 'RGB', 0, 1)
if __name__ == '__main__':
im = grab_screen(0,0,1440,900)
im.show()
Let us create a sample database with a table by the below script:
CREATE DATABASE Test
GO
USE Test
GO
CREATE TABLE dbo.tblTest (Id INT, Name NVARCHAR(50))
Approach 1: Using INFORMATION_SCHEMA.TABLES view
We can write a query like below to check if a tblTest Table exists in the current database.
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = N'tblTest')
BEGIN
PRINT 'Table Exists'
END
The above query checks the existence of the tblTest table across all the schemas in the current database. Instead of this if you want to check the existence of the Table in a specified Schema and the Specified Database then we can write the above query as below:
IF EXISTS (SELECT * FROM Test.INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = N'dbo' AND TABLE_NAME = N'tblTest')
BEGIN
PRINT 'Table Exists'
END
Pros of this Approach: INFORMATION_SCHEMA views are portable across different RDBMS systems, so porting to different RDBMS doesn’t require any change.
Approach 2: Using OBJECT_ID() function
We can use OBJECT_ID()
function like below to check if a tblTest Table exists in the current database.
IF OBJECT_ID(N'dbo.tblTest', N'U') IS NOT NULL
BEGIN
PRINT 'Table Exists'
END
Specifying the Database Name and Schema Name parts for the Table Name is optional. But specifying Database Name and Schema Name provides an option to check the existence of the table in the specified database and within a specified schema, instead of checking in the current database across all the schemas. The below query shows that even though the current database is MASTER database, we can check the existence of the tblTest
table in the dbo
schema in the Test
database.
USE MASTER
GO
IF OBJECT_ID(N'Test.dbo.tblTest', N'U') IS NOT NULL
BEGIN
PRINT 'Table Exists'
END
Pros: Easy to remember. One other notable point to mention about OBJECT_ID()
function is: it provides an option to check the existence of the Temporary Table which is created in the current connection context. All other Approaches checks the existence of the Temporary Table created across all the connections context instead of just the current connection context. Below query shows how to check the existence of a Temporary Table using OBJECT_ID()
function:
CREATE TABLE #TempTable(ID INT)
GO
IF OBJECT_ID(N'TempDB.dbo.#TempTable', N'U') IS NOT NULL
BEGIN
PRINT 'Table Exists'
END
GO
Approach 3: Using sys.Objects Catalog View
We can use the Sys.Objects
catalog view to check the existence of the Table as shown below:
IF EXISTS(SELECT 1 FROM sys.Objects WHERE Object_id = OBJECT_ID(N'dbo.tblTest') AND Type = N'U')
BEGIN
PRINT 'Table Exists'
END
Approach 4: Using sys.Tables Catalog View
We can use the Sys.Tables
catalog view to check the existence of the Table as shown below:
IF EXISTS(SELECT 1 FROM sys.Tables WHERE Name = N'tblTest' AND Type = N'U')
BEGIN
PRINT 'Table Exists'
END
Sys.Tables
catalog view inherits the rows from the Sys.Objects
catalog view, Sys.objects
catalog view is referred to as base view where as sys.Tables
is referred to as derived view. Sys.Tables
will return the rows only for the Table objects whereas Sys.Object
view apart from returning the rows for table objects, it returns rows for the objects like: stored procedure, views etc.
Approach 5: Avoid Using sys.sysobjects System table
We should avoid using sys.sysobjects
System Table directly, direct access to it will be deprecated in some future versions of the Sql Server. As per [Microsoft BOL][1] link, Microsoft is suggesting to use the catalog views sys.objects/sys.tables
instead of sys.sysobjects
system table directly.
IF EXISTS(SELECT name FROM sys.sysobjects WHERE Name = N'tblTest' AND xtype = N'U')
BEGIN
PRINT 'Table Exists'
END

Ansible command-line help, such as ansible-playbook --help
shows how to increase output verbosity by setting the verbose mode (-v) to more verbosity (-vvv) or to connection debugging verbosity (-vvvv). This should give you some of the details you're after in stdout, which you can then be logged.
Here is a practical example (there are several good ones already). I just wanted to add one that is useful to almost any developer.
At some point, developers will need to parse an object as with a response from an API or some type of object or array.
This function is initially called to parse an object which may just contain parameters, but what if the object also contains other objects or arrays? This will need to be addressed, and for the most part the basic function already does this, so the function just calls itself again (after confirming that the key or value is either an object or an array) and parses this new object or array. Ultimately what is returned is a string that creates each parameter on a line by itself for readability, but you could just as easily log the values to a log file or insert into a DB or whatever.
I added the $prefix
parameter to use the parent element to help describe the end variable so that we can see what the value pertains to. It doesn't include things like null values, but this can be amended from this example.
If you have the object:
$apiReturn = new stdClass();
$apiReturn->shippingInfo = new stdClass();
$apiReturn->shippingInfo->fName = "Bill";
$apiReturn->shippingInfo->lName = "Test";
$apiReturn->shippingInfo->address1 = "22 S. Deleware St.";
$apiReturn->shippingInfo->city = "Chandler";
$apiReturn->shippingInfo->state = "AZ";
$apiReturn->shippingInfo->zip = 85225;
$apiReturn->phone = "602-312-4455";
$apiReturn->transactionDetails = array(
"totalAmt" => "100.00",
"currency" => "USD",
"tax" => "5.00",
"shipping" => "5.00"
);
$apiReturn->item = new stdClass();
$apiReturn->item->name = "T-shirt";
$apiReturn->item->color = "blue";
$apiReturn->item->itemQty = 1;
and use:
var_dump($apiReturn);
it will return:
object(stdClass)#1 (4) { ["shippingInfo"]=> object(stdClass)#2 (6) { ["fName"]=> string(4) "Bill" ["lName"]=> string(4) "Test" ["address1"]=> string(18) "22 S. Deleware St." ["city"]=> string(8) "Chandler" ["state"]=> string(2) "AZ" ["zip"]=> int(85225) } ["phone"]=> string(12) "602-312-4455" ["transactionDetails"]=> array(4) { ["totalAmt"]=> string(6) "100.00" ["currency"]=> string(3) "USD" ["tax"]=> string(4) "5.00" ["shipping"]=> string(4) "5.00" } ["item"]=> object(stdClass)#3 (3) { ["name"]=> string(7) "T-shirt" ["color"]=> string(4) "blue" ["itemQty"]=> int(1) } }
and here is the code to parse it into a string with a line break for each parameter:
function parseObj($obj, $prefix = ''){
$stringRtrn = '';
foreach($obj as $key=>$value){
if($prefix){
switch ($key) {
case is_array($key):
foreach($key as $k=>$v){
$stringRtrn .= parseObj($key, $obj);
}
break;
case is_object($key):
$stringRtrn .= parseObj($key, $obj);
break;
default:
switch ($value) {
case is_array($value):
$stringRtrn .= parseObj($value, $key);
break;
case is_object($value):
$stringRtrn .= parseObj($value, $key);
break;
default:
$stringRtrn .= $prefix ."_". $key ." = ". $value ."<br>";
break;
}
break;
}
} else { // end if($prefix)
switch($key){
case is_array($key):
$stringRtrn .= parseObj($key, $obj);
break;
case is_object($key):
$stringRtrn .= parseObj($key, $obj);
break;
default:
switch ($value) {
case is_array($value):
$stringRtrn .= parseObj($value, $key);
break;
case is_object($value):
$stringRtrn .= parseObj($value, $key);
break;
default:
$stringRtrn .= $key ." = ". $value ."<br>";
break;
} // end inner switch
} // end outer switch
} // end else
} // end foreach($obj as $key=>$value)
return $stringRtrn;
} // END parseObj()
This will return the object as follows:
shippingInfo_fName = Bill
shippingInfo_lName = Test
shippingInfo_address1 = 22 S. Deleware St.
shippingInfo_city = Chandler
shippingInfo_state = AZ
shippingInfo_zip = 85225
phone = 602-312-4455
transactionDetails_totalAmt = 100.00
transactionDetails_currency = USD
transactionDetails_tax = 5.00
transactionDetails_shipping = 5.00
item_name = T-shirt
item_color = blue
item_itemQty = 1
I did the nested switch statements to avoid confusion with if . . . ifelse . . . else
, but it was almost as long. If it helps, just ask for the if conditionals and I can paste them for those who need it.
In Swift3, I have used in this way
var hasAddedGeofencesAtleastOnce: Bool {
get {
return UserDefaults.standard.object(forKey: "hasAddedGeofencesAtleastOnce") != nil
}
}
The answer is great if you are to use that multiple times.
I hope it helps :)
1: Create a custom attribute and override method like this:
public class CultureAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
// Retreive culture from GET
string currentCulture = filterContext.HttpContext.Request.QueryString["culture"];
// Also, you can retreive culture from Cookie like this :
//string currentCulture = filterContext.HttpContext.Request.Cookies["cookie"].Value;
// Set culture
Thread.CurrentThread.CurrentCulture = new CultureInfo(currentCulture);
Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(currentCulture);
}
}
2: In App_Start, find FilterConfig.cs, add this attribute. (this works for WHOLE application)
public class FilterConfig
{
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
// Add custom attribute here
filters.Add(new CultureAttribute());
}
}
That's it !
If you want to define culture for each controller/action in stead of whole application, you can use this attribute like this:
[Culture]
public class StudentsController : Controller
{
}
Or:
[Culture]
public ActionResult Index()
{
return View();
}
You cannot use the datetime function using the Java wrapper "ContentValues". Either you can use :
SQLiteDatabase.execSQL so you can enter a raw SQL query.
mDb.execSQL("INSERT INTO "+DATABASE_TABLE+" VALUES (null, datetime()) ");
Or the java date time capabilities :
// set the format to sql date time
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = new Date();
ContentValues initialValues = new ContentValues();
initialValues.put("date_created", dateFormat.format(date));
long rowId = mDb.insert(DATABASE_TABLE, null, initialValues);
You are triggering the event before the event is even bound.
Just move the triggering
of the event to after attaching the event.
$(document).ready(function() {
$("#checkbox_div input:radio").click(function() {
alert("clicked");
});
$("input:radio:first").prop("checked", true).trigger("click");
});
There are a few things wrong here:
First, terminology. "Epoch" refers to the starting point of something. The "Unix Epoch" is Midnight, January 1st 1970 UTC. You can't convert an arbitrary "date string to epoch". You probably meant "Unix Time", which is often erroneously called "Epoch Time".
.unix()
returns Unix Time in whole seconds, but the default moment
constructor accepts a timestamp in milliseconds. You should instead use .valueOf()
to return milliseconds. Note that calling .unix()*1000
would also work, but it would result in a loss of precision.
You're parsing a string without providing a format specifier. That isn't a good idea, as values like 1/2/2014 could be interpreted as either February 1st or as January 2nd, depending on the locale of where the code is running. (This is also why you get the deprecation warning in the console.) Instead, provide a format string that matches the expected input, such as:
moment("10/15/2014 9:00", "M/D/YYYY H:mm")
.calendar()
has a very specific use. If you are near to the date, it will return a value like "Today 9:00 AM". If that's not what you expected, you should use the .format()
function instead. Again, you may want to pass a format specifier.
To answer your questions in comments, No - you don't need to call .local()
or .utc()
.
Putting it all together:
var ts = moment("10/15/2014 9:00", "M/D/YYYY H:mm").valueOf();
var m = moment(ts);
var s = m.format("M/D/YYYY H:mm");
alert("Values are: ts = " + ts + ", s = " + s);
On my machine, in the US Pacific time zone, it results in:
Values are: ts = 1413388800000, s = 10/15/2014 9:00
Since the input value is interpreted in terms of local time, you will get a different value for ts
if you are in a different time zone.
Also note that if you really do want to work with whole seconds (possibly losing precision), moment has methods for that as well. You would use .unix()
to return the timestamp in whole seconds, and moment.unix(ts)
to parse it back to a moment.
var ts = moment("10/15/2014 9:00", "M/D/YYYY H:mm").unix();
var m = moment.unix(ts);
This is exactly how it worked for me. For some reason the above code failed.

You will need to build the jar file first. Here is the syntax to run the main class from a jar file.
java -jar path/to/your/jarfile.jar fully.qualified.package.Application
A simple Javascript function that makes the content inside a page-element unselectable:
function makeUnselectable(elem) {
if (typeof(elem) == 'string')
elem = document.getElementById(elem);
if (elem) {
elem.onselectstart = function() { return false; };
elem.style.MozUserSelect = "none";
elem.style.KhtmlUserSelect = "none";
elem.unselectable = "on";
}
}
I got this to work on the first try by adding position:absolute; bottom:0;
to the div ID inside the CSS. I did not add the parent style position:relative;
.
It is working perfect in both Firefox and IE 8, have not tried it in IE 7 yet.
Instead of adding margin why not add a padding-right of 1px to each col-xs-2 coz padding would be still a part of that div
.col-xs-2 :not(.col-xs-2:nth-child(5))
{padding-right:1px}
There are 3 scenarios, you describe:
.c
files and with int i;
in the header..c
files and with int i=100;
in the header (or any other value; that doesn't matter)..c
file and with int i=100;
in the header.In each scenario, imagine the contents of the header file inserted into the .c
file and this .c
file compiled into a .o
file and then these linked together.
Then following happens:
works fine because of the already mentioned "tentative definitions": every .o
file contains one of them, so the linker says "ok".
doesn't work, because both .o
files contain a definition with a value, which collide (even if they have the same value) - there may be only one with any given name in all .o
files which are linked together at a given time.
works of course, because you have only one .o
file and so no possibility for collision.
IMHO a clean thing would be
extern int i;
or just int i;
into the header file,int i = 100;
) into file1.c
. In this case, this initialization gets used at the start of the program and the corresponding line in main()
can be omitted. (Besides, I hope the naming is only an example; please don't name any global variables as i
in real programs.)Because this question is tagged with regex I'm going to answer with poor man's solution in this situation:
$html = preg_replace('#<script(.*?)>(.*?)</script>#is', '', $html);
However, regular expressions are not for parsing HTML/XML, even if you write the perfect expression it will break eventually, it's not worth it, although, in some cases it's useful to quickly fix some markup, and as it is with quick fixes, forget about security. Use regex only on content/markup you trust.
Remember, anything that user inputs should be considered not safe.
Better solution here would be to use DOMDocument
which is designed for this.
Here is a snippet that demonstrate how easy, clean (compared to regex), (almost) reliable and (nearly) safe is to do the same:
<?php
$html = <<<HTML
...
HTML;
$dom = new DOMDocument();
$dom->loadHTML($html);
$script = $dom->getElementsByTagName('script');
$remove = [];
foreach($script as $item)
{
$remove[] = $item;
}
foreach ($remove as $item)
{
$item->parentNode->removeChild($item);
}
$html = $dom->saveHTML();
I have removed the HTML intentionally because even this can bork.
None of these gave me a satisfactory answer so in the end I got what I wanted with the key
prop, useRef and some random id generator like shortid
.
Basically, I wanted some chat application to play itself out the first time someone opens the app. So, I needed full control over when and what the answers are updated with the ease of async await.
Example code:
function sleep(ms) {
return new Promise(resolve => setTimeout(resolve, ms));
}
// ... your JSX functional component, import shortid somewhere
const [render, rerender] = useState(shortid.generate())
const messageList = useRef([
new Message({id: 1, message: "Hi, let's get started!"})
])
useEffect(()=>{
await sleep(500)
messageList.current.push(new Message({id: 1, message: "What's your name?"}))
// ... more stuff
// now trigger the update
rerender(shortid.generate())
}, [])
// only the component with the right render key will update itself, the others will stay as is and won't rerender.
return <div key={render}>{messageList.current}</div>
In fact this also allowed me to roll something like a chat message with a rolling .
const waitChat = async (ms) => {
let text = "."
for (let i = 0; i < ms; i += 200) {
if (messageList.current[messageList.current.length - 1].id === 100) {
messageList.current = messageList.current.filter(({id}) => id !== 100)
}
messageList.current.push(new Message({
id: 100,
message: text
}))
if (text.length === 3) {
text = "."
} else {
text += "."
}
rerender(shortid.generate())
await sleep(200)
}
if (messageList.current[messageList.current.length - 1].id === 100) {
messageList.current = messageList.current.filter(({id}) => id !== 100)
}
}
For anyone having this error after spliting modules check your routes, the following happened to me:
public-routing.module.ts:
const routes: Routes = [
{ path: '', component: HomeComponent },
{ path: '**', redirectTo: 'home' } // ? This was my mistake
{ path: 'home', component: HomeComponent },
{ path: 'privacy-policy', component: PrivacyPolicyComponent },
{ path: 'credits', component: CreditsComponent },
{ path: 'contact', component: ContactComponent },
{ path: 'news', component: NewsComponent },
{ path: 'presentation', component: PresentationComponent }
]
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class PublicRoutingModule { }
app-routing.module.ts:
const routes: Routes = [
];
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule { }
Move { path: '**', redirectTo: 'home' }
to your AppRoutingModule:
public-routing.module.ts:
const routes: Routes = [
{ path: '', component: HomeComponent },
{ path: 'home', component: HomeComponent },
{ path: 'privacy-policy', component: PrivacyPolicyComponent },
{ path: 'credits', component: CreditsComponent },
{ path: 'contact', component: ContactComponent },
{ path: 'news', component: NewsComponent },
{ path: 'presentation', component: PresentationComponent }
]
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class PublicRoutingModule { }
app-routing.module.ts:
const routes: Routes = [
{ path: '**', redirectTo: 'home' }
];
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule { }

There is anew tool called Codename one: One SDK based on JAVA to code in WP8, Android, iOS with all extensive features
Features:
From Angular 6.1 you can use the keyvalue pipe:
<div *ngFor="let item of testObject | keyvalue">
Key: <b>{{item.key}}</b> and Value: <b>{{item.value}}</b>
</div>
But it has the inconvenient that sorts the resulting list by the key value. If you need something neutral:
@Pipe({ name: 'keyValueUnsorted', pure: false })
export class KeyValuePipe implements PipeTransform {
transform(input: any): any {
let keys = [];
for (let key in input) {
if (input.hasOwnProperty(key)) {
keys.push({ key: key, value: input[key]});
}
}
return keys;
}
}
Don't forget to specify the pure:false pipe attribute. In this case, the pipe is invoked on each change-detection cycle, even if the input reference has not changed (so is the case when you add properties to an object).
If your dump file doesn't have DEFINER

At the end:

Nice classes by Rich Tebb! I've been using DisplayAttribute and the code did not work for me. The only thing I've added is handling of DisplayAttribute. Brief search yielded that this attribute is new to MVC3 & .Net 4 and does almost the same thing plus more. Here's a modified version of the method:
public static string GetPropertyDisplayString<T>(Expression<Func<T, object>> propertyExpression)
{
var memberInfo = GetPropertyInformation(propertyExpression.Body);
if (memberInfo == null)
{
throw new ArgumentException(
"No property reference expression was found.",
"propertyExpression");
}
var displayAttribute = memberInfo.GetAttribute<DisplayAttribute>(false);
if (displayAttribute != null)
{
return displayAttribute.Name;
}
else
{
var displayNameAttribute = memberInfo.GetAttribute<DisplayNameAttribute>(false);
if (displayNameAttribute != null)
{
return displayNameAttribute.DisplayName;
}
else
{
return memberInfo.Name;
}
}
}

Flexboxes should now be used to vertically (or even horizontally) align items.
body {
height: 150px;
border: 5px solid cyan;
font-size: 50px;
display: flex;
align-items: center; /* Vertical center alignment */
justify-content: center; /* Horizontal center alignment */
}
_x000D_
Middle
_x000D_
A good guide to flexbox can be read on CSS Tricks. Thanks Ben (from comments) for pointing it out. I didn't have time to update.
A good guy named Mahendra posted a very working solution here.
The following class should make the element horizontally and vertically centered to its parent.
.absolute-center {
/* Internet Explorer 10 */
display: -ms-flexbox;
-ms-flex-pack: center;
-ms-flex-align: center;
/* Firefox */
display: -moz-box;
-moz-box-pack: center;
-moz-box-align: center;
/* Safari, Opera, and Chrome */
display: -webkit-box;
-webkit-box-pack: center;
-webkit-box-align: center;
/* W3C */
display: box;
box-pack: center;
box-align: center;
}
A simpler way
git add . -A
git commit -m "Deleted some files..."
git push origin master
-A Update the index not only where the working tree has a file matching but also where the index already has an entry. This adds, modifies, and removes index entries to match the working tree. Taken from (http://git-scm.com/docs/git-add)
sed -i "" -e $'4 a\\n''Project_Name=sowstest' start
If you're using a Storyboard and you're coming from a push segue, you could also just override shouldPerformSegueWithIdentifier:sender:
.
I would avoid using component state since this could be difficult to manage and prone to issues that can be difficult to troubleshoot.
You should use either cookies
or localStorage
for persisting a user's session data. You can also use a closure as a wrapper around your cookie
or localStorage
data.
Here is a simple example of a UserProfile
closure that will hold the user's name.
var UserProfile = (function() {
var full_name = "";
var getName = function() {
return full_name; // Or pull this from cookie/localStorage
};
var setName = function(name) {
full_name = name;
// Also set this in cookie/localStorage
};
return {
getName: getName,
setName: setName
}
})();
export default UserProfile;
When a user logs in, you can populate this object with user name, email address etc.
import UserProfile from './UserProfile';
UserProfile.setName("Some Guy");
Then you can get this data from any component in your app when needed.
import UserProfile from './UserProfile';
UserProfile.getName();
Using a closure will keep data outside of the global namespace, and make it is easily accessible from anywhere in your app.
git mv
moves the file, updating the index to record the replaced file path, as well as updating any affected git submodules. Unlike a manual move, it also detects case-only renames that would not otherwise be detected as a change by git.
It is similar (though not identical) in behavior to moving the file externally to git, removing the old path from the index using git rm
, and adding the new one to the index using git add
.
This question has a lot of great partial answers. This answer is an attempt to combine them into a single cohesive answer. Additionally, one thing not called out by any of the other answers is the fact that the man page actually does mostly answer the question, but it's perhaps less obvious than it could be.
Three different effects are called out in the man page:
The file, directory, or symlink is moved in the filesystem:
git-mv - Move or rename a file, a directory, or a symlink
The index is updated, adding the new path and removing the previous one:
The index is updated after successful completion, but the change must still be committed.
Moved submodules are updated to work at the new location:
Moving a submodule using a gitfile (which means they were cloned with a Git version 1.7.8 or newer) will update the gitfile and core.worktree setting to make the submodule work in the new location. It also will attempt to update the submodule.<name>.path setting in the gitmodules(5) file and stage that file (unless -n is used).
As mentioned in this answer, git mv
is very similar to moving the file, adding the new path to the index, and removing the previous path from the index:
mv oldname newname
git add newname
git rm oldname
However, as this answer points out, git mv
is not strictly identical to this in behavior. Moving the file via git mv
adds the new path to the index, but not any modified content in the file. Using the three individual commands, on the other hand, adds the entire file to the index, including any modified content. This could be relevant when using a workflow which patches the index, rather than adding all changes in the file.
Additionally, as mentioned in this answer and this comment, git mv
has the added benefit of handling case-only renames on file systems that are case-insensitive but case-preserving, as is often the case in current macOS and Windows file systems. For example, in such systems, git would not detect that the file name has changed after moving a file via mv Mytest.txt MyTest.txt
, whereas using git mv Mytest.txt MyTest.txt
would successfully update its name.
You should add the code in project level gradle file for generating apk overwriting over errors
If you are getting such error, the only reason could be you using a Distribution profile rather than a development profile in Xcode or a missing Entitlement property. If you are not using the Entitlements.plist, then the only possible error could be the app is getting packaged with a distribution profile. You could verify this confirming the build logs. To change this, go to Build Setting of the project and verify Code Signing Entity setting. For debugging to work, this setting should be a developer profile for the configuration that you are currently using.
https://developer.apple.com/library/ios/#qa/qa1682/_index.html
For instant results, delete all mobile provisioning profiles from xcode and install the developer profile that you intend to use.
$value = 23;
$rounded_value = $value - ($value % 10 - 10);

I've actually just copied the first answer here and turned it into a more ux-convenient regex which needs one upper, one lower and at least 8 chars but accepts everything "in between".
This one is an example-regex which requires
IMPORTANT: This regex will also except all other characters e.g. numbers, special characters like $,#,! etc. - as long as the rules 1. to 3. match the input string
^(?=.*[a-z])(?=.*[A-Z]).{8,}$
Mind the "." alomst at the end of the regex. This will match almost any (and afaik any readable) character
In case of NULL
columns it is better to use IF
clause like this which combine the two functions of : CONCAT
and COALESCE
and uses special chars between the columns in result like space or '_'
SELECT FirstName , LastName ,
IF(FirstName IS NULL AND LastName IS NULL, NULL,' _ ',CONCAT(COALESCE(FirstName ,''), COALESCE(LastName ,'')))
AS Contact_Phone FROM TABLE1
Well, you are using both frame.setSize()
and frame.pack()
.
You should use one of them at one time.
Using setSize()
you can give the size of frame you want but if you use pack()
, it will automatically change the size of the frames according to the size of components in it. It will not consider the size you have mentioned earlier.
Try removing frame.pack()
from your code or putting it before setting size and then run it.
You can simply bind $this->getParameter('app.version')
in controller to twig param and then render it.
In my case, using Android Studio 4.0, the below solved the issue;
Add to 'gradle.properties' file;
android.injected.testOnly=false
On the server.. In our environment, we're running Apache2 on Windows Server 2003.
Suppose Apache is serving our repository from C:\repo\MyProject
The actual repository is in C:\repo\MyProject\db
and the configuration is in C:\repo\MyProject\conf
So the passwords are in: C:\repo\MyProject.htaccess
They're encrypted, a tool similar to this: http://tools.dynamicdrive.com/password/
If you're just quickly looking to keep a cmd instance open instead of exiting immediately, simply doing the following is enough
set /p asd="Hit enter to continue"
at the end of your script and it'll keep the window open.
Note that this'll set asd
as an environment variable, and can be replaced with anything else.
Here is what I do:
var uriParams = getSearchParameters();
alert(uriParams.c);
// background functions:
// Get object/associative array of URL parameters
function getSearchParameters () {
var prmstr = window.location.search.substr(1);
return prmstr !== null && prmstr !== "" ? transformToAssocArray(prmstr) : {};
}
// convert parameters from url-style string to associative array
function transformToAssocArray (prmstr) {
var params = {},
prmarr = prmstr.split("&");
for (var i = 0; i < prmarr.length; i++) {
var tmparr = prmarr[i].split("=");
params[tmparr[0]] = tmparr[1];
}
return params;
}
if( ($_POST) && (!empty($_POST['cover_image'])) ) //verifies if post exists and cover_image is not empty
{
//execute whatever code you want
}
For whatever reason I've never liked the clearing approaches, I rely on floats and percentage widths for things like this.
Here's something that works in simple cases:
#content {
overflow:auto;
width: 600px;
background: gray;
}
#left, #right {
width: 40%;
margin:5px;
padding: 1em;
background: white;
}
#left { float:left; }
#right { float:right; }
If you put some content in you'll see that it works:
<div id="content">
<div id="left">
<div id="object1">some stuff</div>
<div id="object2">some more stuff</div>
</div>
<div id="right">
<div id="object3">unas cosas</div>
<div id="object4">mas cosas para ti</div>
</div>
</div>

If you are planning to draw a lot of pixel, it's a lot more efficient to use the image data of the canvas to do pixel drawing.
var canvas = document.getElementById("myCanvas");
var canvasWidth = canvas.width;
var canvasHeight = canvas.height;
var ctx = canvas.getContext("2d");
var canvasData = ctx.getImageData(0, 0, canvasWidth, canvasHeight);
// That's how you define the value of a pixel //
function drawPixel (x, y, r, g, b, a) {
var index = (x + y * canvasWidth) * 4;
canvasData.data[index + 0] = r;
canvasData.data[index + 1] = g;
canvasData.data[index + 2] = b;
canvasData.data[index + 3] = a;
}
// That's how you update the canvas, so that your //
// modification are taken in consideration //
function updateCanvas() {
ctx.putImageData(canvasData, 0, 0);
}
Then, you can use it in this way :
drawPixel(1, 1, 255, 0, 0, 255);
drawPixel(1, 2, 255, 0, 0, 255);
drawPixel(1, 3, 255, 0, 0, 255);
updateCanvas();
For more information, you can take a look at this Mozilla blog post : http://hacks.mozilla.org/2009/06/pushing-pixels-with-canvas/
You can use this method also it will act like that
thadari=[1,2,3,4,5,6]
#Front Two(Left)
print(thadari[:2])

#Last Two(Right)# edited
print(thadari[-2:])
[5,6]
#mid
mid = len(thadari) //2
lefthalf = thadari[:mid]
[1,2,3]
righthalf = thadari[mid:]
[4,5,6]
Hope it will help
You can just use the View.setId(integer)
for this. In the XML, even though you're setting a String id, this gets converted into an integer. Due to this, you can use any (positive) Integer for the Views
you add programmatically.
According to
View
documentationThe identifier does not have to be unique in this view's hierarchy. The identifier should be a positive number.
So you can use any positive integer you like, but in this case there can be some views with equivalent id's. If you want to search for some view in hierarchy calling to setTag with some key objects may be handy.
Credits to this answer.
listView.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View view) {
return false;
}
});
Definitely does the trick.
You can not alter constraints ever but you can drop them and then recreate.
Have look on this
ALTER TABLE your_table DROP CONSTRAINT ACTIVEPROG_FKEY1;
and then recreate it with ON DELETE CASCADE
like this
ALTER TABLE your_table
add CONSTRAINT ACTIVEPROG_FKEY1 FOREIGN KEY(ActiveProgCode) REFERENCES PROGRAM(ActiveProgCode)
ON DELETE CASCADE;
hope this help
The same problem arrised for me when I installed Kaliko CMS Nuget Package. When I removed it, it started working fine again. So, your problem could be because of a recently installed Nuget Package. Uninstall it and your solution will work just fine.
In Access 2007 - 2010, go to Database Tools and click Compact and Repair Database, and it will automatically reset the ID.
The following code shows how to read values from an HTML form. As @pimvdb said you need to use the request.on('data'...) to capture the contents of the body.
const http = require('http')
const server = http.createServer(function(request, response) {
console.dir(request.param)
if (request.method == 'POST') {
console.log('POST')
var body = ''
request.on('data', function(data) {
body += data
console.log('Partial body: ' + body)
})
request.on('end', function() {
console.log('Body: ' + body)
response.writeHead(200, {'Content-Type': 'text/html'})
response.end('post received')
})
} else {
console.log('GET')
var html = `
<html>
<body>
<form method="post" action="http://localhost:3000">Name:
<input type="text" name="name" />
<input type="submit" value="Submit" />
</form>
</body>
</html>`
response.writeHead(200, {'Content-Type': 'text/html'})
response.end(html)
}
})
const port = 3000
const host = '127.0.0.1'
server.listen(port, host)
console.log(`Listening at http://${host}:${port}`)
If you use something like Express.js and Bodyparser then it would look like this since Express will handle the request.body concatenation
var express = require('express')
var fs = require('fs')
var app = express()
app.use(express.bodyParser())
app.get('/', function(request, response) {
console.log('GET /')
var html = `
<html>
<body>
<form method="post" action="http://localhost:3000">Name:
<input type="text" name="name" />
<input type="submit" value="Submit" />
</form>
</body>
</html>`
response.writeHead(200, {'Content-Type': 'text/html'})
response.end(html)
})
app.post('/', function(request, response) {
console.log('POST /')
console.dir(request.body)
response.writeHead(200, {'Content-Type': 'text/html'})
response.end('thanks')
})
port = 3000
app.listen(port)
console.log(`Listening at http://localhost:${port}`)
var
variables still have a type - and the compiler error message says this type must be established during the declaration.
The specific request (assigning an initial null value) can be done, but I don't recommend it. It doesn't provide an advantage here (as the type must still be specified) and it could be viewed as making the code less readable:
var x = (String)null;
Which is still "type inferred" and equivalent to:
String x = null;
The compiler will not accept var x = null
because it doesn't associate the null with any type - not even Object. Using the above approach, var x = (Object)null
would "work" although it is of questionable usefulness.
Generally, when I can't use var
's type inference correctly then
The second approach can be done by moving code into methods or functions.
This was added to the upgrade documentation on Dec 29, 2015, so if you upgraded before then you probably missed it.
When fetching any attribute from the model it checks if that column should be cast as an integer, string, etc.
By default, for auto-incrementing tables, the ID is assumed to be an integer in this method:
https://github.com/laravel/framework/blob/5.2/src/Illuminate/Database/Eloquent/Model.php#L2790
So the solution is:
class UserVerification extends Model
{
protected $primaryKey = 'your_key_name'; // or null
public $incrementing = false;
// In Laravel 6.0+ make sure to also set $keyType
protected $keyType = 'string';
}
linux: shutdown() causes listener thread select() to awake and produce error. shutdown(); close(); will lead to endless wait.
winsock: vice versa - shutdown() has no effect, while close() is successfully catched.
I was able to get this to work. I will describe my application and the integration test here.

Let's assume that we have a simple entity called Todo
which source code looks as follows:
@Entity
@Table(name="todos")
public class Todo {
public static final int MAX_LENGTH_DESCRIPTION = 500;
public static final int MAX_LENGTH_TITLE = 100;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Column(name = "description", nullable = true, length = MAX_LENGTH_DESCRIPTION)
private String description;
@Column(name = "title", nullable = false, length = MAX_LENGTH_TITLE)
private String title;
@Version
private long version;
}
Our repository interface has a single method called updateTitle()
which updates the title of a todo entry. The source code of the TodoRepository
interface looks as follows:
import net.petrikainulainen.spring.datajpa.todo.model.Todo;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Modifying;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import java.util.List;
public interface TodoRepository extends JpaRepository<Todo, Long> {
@Modifying
@Query("Update Todo t SET t.title=:title WHERE t.id=:id")
public void updateTitle(@Param("id") Long id, @Param("title") String title);
}
The updateTitle()
method is not annotated with the @Transactional
annotation because I think that it is best to use a service layer as a transaction boundary.
The Integration Test
The Integration Test uses DbUnit, Spring Test and Spring-Test-DBUnit. It has three components which are relevant to this problem:
These components are described with more details in the following.
The name of the DbUnit dataset file which is used to initialize the database to known state is toDoData.xml and its content looks as follows:
<dataset>
<todos id="1" description="Lorem ipsum" title="Foo" version="0"/>
<todos id="2" description="Lorem ipsum" title="Bar" version="0"/>
</dataset>
The name of the DbUnit dataset which is used to verify that the title of the todo entry is updated is called toDoData-update.xml and its content looks as follows (for some reason the version of the todo entry was not updated but the title was. Any ideas why?):
<dataset>
<todos id="1" description="Lorem ipsum" title="FooBar" version="0"/>
<todos id="2" description="Lorem ipsum" title="Bar" version="0"/>
</dataset>
The source code of the actual integration test looks as follows (Remember to annotate the test method with the @Transactional
annotation):
import com.github.springtestdbunit.DbUnitTestExecutionListener;
import com.github.springtestdbunit.TransactionDbUnitTestExecutionListener;
import com.github.springtestdbunit.annotation.DatabaseSetup;
import com.github.springtestdbunit.annotation.ExpectedDatabase;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.annotation.Rollback;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.TestExecutionListeners;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.support.DependencyInjectionTestExecutionListener;
import org.springframework.test.context.support.DirtiesContextTestExecutionListener;
import org.springframework.test.context.transaction.TransactionalTestExecutionListener;
import org.springframework.transaction.annotation.Transactional;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {PersistenceContext.class})
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
DirtiesContextTestExecutionListener.class,
TransactionalTestExecutionListener.class,
DbUnitTestExecutionListener.class })
@DatabaseSetup("todoData.xml")
public class ITTodoRepositoryTest {
@Autowired
private TodoRepository repository;
@Test
@Transactional
@ExpectedDatabase("toDoData-update.xml")
public void updateTitle_ShouldUpdateTitle() {
repository.updateTitle(1L, "FooBar");
}
}
After I run the integration test, the test passes and the title of the todo entry is updated. The only problem which I am having is that the version field is not updated. Any ideas why?
I undestand that this description is a bit vague. If you want to get more information about writing integration tests for Spring Data JPA repositories, you can read my blog post about it.
Find the PID of a process that uses a port on Windows (e.g. port: "9999")
netstat -aon | find "9999"
-a
Displays all connections and listening ports.
-o
Displays the owning process ID associated with each connection.
-n
Displays addresses and port numbers in numerical form.
Output:
TCP 0.0.0.0:9999 0.0.0.0:0 LISTENING 15776
Then kill the process by PID
taskkill /F /PID 15776
/F
- Specifies to forcefully terminate the process(es).
Note: You may need an extra permission (run from administrator) to kill some certain processes
I use this:
function parseJsonDate(jsonDateString){
return new Date(parseInt(jsonDateString.replace('/Date(', '')));
}
Update 2018:
This is an old question. Instead of still using this old non standard serialization format I would recommend to modify the server code to return better format for date. Either an ISO string containing time zone information, or only the milliseconds. If you use only the milliseconds for transport it should be UTC
on server and client.
2018-07-31T11:56:48Z
- ISO string can be parsed using new Date("2018-07-31T11:56:48Z")
and obtained from a Date
object
using dateObject.toISOString()
1533038208000
- milliseconds since midnight January 1, 1970, UTC - can be parsed using new Date(1533038208000) and obtained from a Date
object
using dateObject.getTime()
If you want to know the day of the week for your code to do something with it, DateTime.Now.DayOfWeek
will do the job.
If you want to display the day of week to the user, DateTime.Now.ToString("dddd")
will give you the localized day name, according to the current culture (MSDN info on the "dddd" format string).
You are checking Parent
properties for null in your delegate. The same should work with lambda expressions too.
List<AnalysisObject> analysisObjects = analysisObjectRepository
.FindAll()
.Where(x =>
(x.ID == packageId) ||
(x.Parent != null &&
(x.Parent.ID == packageId ||
(x.Parent.Parent != null && x.Parent.Parent.ID == packageId)))
.ToList();
java -version
java -showversion

For some reason classLoader.getResource()
always returned null when I deployed the web application to WildFly 14. getting classLoader from getClass().getClassLoader()
or Thread.currentThread().getContextClassLoader()
returns null.
getClass().getClassLoader()
API doc says,
"Returns the class loader for the class. Some implementations may use null to represent the bootstrap class loader. This method will return null in such implementations if this class was loaded by the bootstrap class loader."
may be if you are using WildFly and yours web application try this
request.getServletContext().getResource()
returned the resource url. Here request is an object of ServletRequest.
you need to store the token while creating for 1st registration. When you retrieve data from login table you need to differentiate entered date with current date if it is more than 1 day (24 hours) you need to display message like your token is expired.

Here is another one, I think. Just for reference. Let's set a variable to be an instantance of class StringVar
If you program Tk using the Tcl language, you can ask the system to let you know when a variable is changed. The Tk toolkit can use this feature, called tracing, to update certain widgets when an associated variable is modified.
There’s no way to track changes to Python variables, but Tkinter allows you to create variable wrappers that can be used wherever Tk can use a traced Tcl variable.
text = StringVar()
self.depositLabel = Label(self.__mainWindow, text = self.labelText, textvariable = text)
^^^^^^^^^^^^^^^^^
def depositCallBack(self,event):
text.set('change the value')
Basically the assert keyword meaning is that if the condition is not true then it through an assertionerror else it continue for example in python.

The best site to test website and see them realtime on MAC Safari is by using
They have like 25 free minutes of first time testing and then 10 free mins each day..You can even test your pages from your local PC by using their WEB TUNNEL Feature
I tested 7 to 8 pages in browserstack...And I think they have some java debugging tool in the upper right corner that is great help
This comes from the official site of Chome-devtools and it helps. Here i quote:
- Queuing If a request is queued it indicated that:
- The request was postponed by the rendering engine because it's considered lower priority than critical resources (such as scripts/styles). This often happens with images.
- The request was put on hold to wait for an unavailable TCP socket that's about to free up.
- The request was put on hold because the browser only allows six TCP connections per origin on HTTP 1. Time spent making disk cache entries (typically very quick.)
- Stalled/Blocking Time the request spent waiting before it could be sent. It can be waiting for any of the reasons described for Queueing. Additionally, this time is inclusive of any time spent in proxy negotiation.
I found an easy way to do this -
Just enter a command like this -
>mvn -Dtest=TestClassName#methodname -Dmaven.surefire.debug test
It will start listening to 5005 port. Now just create a remote debugging in Eclipse through Debug Configurations for localhost(any host) and port 5005.

The key difference: NSMutableDictionary can be modified in place, NSDictionary cannot. This is true for all the other NSMutable* classes in Cocoa. NSMutableDictionary is a subclass of NSDictionary, so everything you can do with NSDictionary you can do with both. However, NSMutableDictionary also adds complementary methods to modify things in place, such as the method setObject:forKey:
.
You can convert between the two like this:
NSMutableDictionary *mutable = [[dict mutableCopy] autorelease];
NSDictionary *dict = [[mutable copy] autorelease];
Presumably you want to store data by writing it to a file. NSDictionary has a method to do this (which also works with NSMutableDictionary):
BOOL success = [dict writeToFile:@"/file/path" atomically:YES];
To read a dictionary from a file, there's a corresponding method:
NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:@"/file/path"];
If you want to read the file as an NSMutableDictionary, simply use:
NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithContentsOfFile:@"/file/path"];
In Android Studio 1.0 - 1.1b4, I found this to be the easiest way to remove a module:
Open settings.gradle
found under Gradle Scripts
Delete module's name from the include statement
Sync Project with Gradle Files
Optionally, delete it manually from the project folder
Example
Old:
include ':app', ':greendao'
New:
include ':app'
By "use install a Maven plugin and use it" I am sure you are looking for a Eclipse plugin that will perform Maven functions within the IDE. If so, M2E is a good choice. You will find a lot of help within the Eclipse installation once you install M2E.
That said -- considering that you are starting off using Maven -- it would go a long way to have a good understanding of the basic concepts. Using M2E could hide some of the details which could lead to incomplete or incorrect interpretation of Maven's behavior and therefore problems downstream.
Some good Maven online references are:
In xcode5 from Preferences, Accounts, (select your account), View Details, press refresh button. then select Provision Profile in build settings.
You will need to get the textbox via javascript when moving the mouse over it and change its type
to text
. And when moving it out, you will want to change it back to password
. No chance of doing this in pure CSS.
HTML:
<input type="password" name="password" id="myPassword" size="30" />
<img src="theicon" onmouseover="mouseoverPass();" onmouseout="mouseoutPass();" />
JS:
function mouseoverPass(obj) {
var obj = document.getElementById('myPassword');
obj.type = "text";
}
function mouseoutPass(obj) {
var obj = document.getElementById('myPassword');
obj.type = "password";
}
Personally, I'm reluctant to use these for anything but debugging messages. I have done it, but I try not to show that kind of information to customers or end users. My customers are not engineers and are sometimes not computer savvy. I might log this info to the console, but, as I said, reluctantly except for debug builds or for internal tools. I suppose it does depend on the customer base you have, though.
sys.path returns the list of paths
sys.path
A list of strings that specifies the search path for modules. Initialized from the environment variable PYTHONPATH, plus an installation-dependent default.
As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter. If the script directory is not available (e.g. if the interpreter is invoked interactively or if the script is read from standard input), path[0] is the empty string, which directs Python to search modules in the current directory first. Notice that the script directory is inserted before the entries inserted as a result of PYTHONPATH.
import sys
dirs=sys.path
for path in dirs:
print(path)
or you can print only first path by
print(dir[0])
list comprehension formula:
[<value_when_condition_true> if <condition> else <value_when_condition_false> for value in list_name]
thus you can do it like this:
[y for y in a if y not in b]
Only for demonstration purpose : [y if y not in b else False for y in a ]
This code will display loading on the button label, and set button to disable state, then after processing, re-enable and return back the original button text:
$(function () {
$(".btn-Loading").each(function (idx, elm) {
$(elm).click(function () {
//do processing
if ($(".input-validation-error").length > 0)
return;
$(this).attr("label", $(this).text()).text("loading ....");
$(this).delay(1000).animate({ disabled: true }, 1000, function () {
//original event call
$.when($(elm).delay(1000).one("click")).done(function () {
$(this).animate({ disabled: false }, 1000, function () {
$(this).text($(this).attr("label"));
})
});
//processing finalized
});
});
});
// and fire it after definition
}
);
A struct (without a typedef) often needs to (or should) be with the keyword struct when used.
struct A; // forward declaration
void function( struct A *a ); // using the 'incomplete' type only as pointer
If you typedef your struct you can leave out the struct keyword.
typedef struct A A; // forward declaration *and* typedef
void function( A *a );
Note that it is legal to reuse the struct name
Try changing the forward declaration to this in your code:
typedef struct context context;
It might be more readable to do add a suffix to indicate struct name and type name:
typedef struct context_s context_t;
To elaborate on everyone's great answers, here is the implementation that was used in the Mozilla Fathom project:
/**
* Yield an element and each of its ancestors.
*/
export function *ancestors(element) {
yield element;
let parent;
while ((parent = element.parentNode) !== null && parent.nodeType === parent.ELEMENT_NODE) {
yield parent;
element = parent;
}
}
/**
* Return whether an element is practically visible, considering things like 0
* size or opacity, ``visibility: hidden`` and ``overflow: hidden``.
*
* Merely being scrolled off the page in either horizontally or vertically
* doesn't count as invisible; the result of this function is meant to be
* independent of viewport size.
*
* @throws {Error} The element (or perhaps one of its ancestors) is not in a
* window, so we can't find the `getComputedStyle()` routine to call. That
* routine is the source of most of the information we use, so you should
* pick a different strategy for non-window contexts.
*/
export function isVisible(fnodeOrElement) {
// This could be 5x more efficient if https://github.com/w3c/csswg-drafts/issues/4122 happens.
const element = toDomElement(fnodeOrElement);
const elementWindow = windowForElement(element);
const elementRect = element.getBoundingClientRect();
const elementStyle = elementWindow.getComputedStyle(element);
// Alternative to reading ``display: none`` due to Bug 1381071.
if (elementRect.width === 0 && elementRect.height === 0 && elementStyle.overflow !== 'hidden') {
return false;
}
if (elementStyle.visibility === 'hidden') {
return false;
}
// Check if the element is irrevocably off-screen:
if (elementRect.x + elementRect.width < 0 ||
elementRect.y + elementRect.height < 0
) {
return false;
}
for (const ancestor of ancestors(element)) {
const isElement = ancestor === element;
const style = isElement ? elementStyle : elementWindow.getComputedStyle(ancestor);
if (style.opacity === '0') {
return false;
}
if (style.display === 'contents') {
// ``display: contents`` elements have no box themselves, but children are
// still rendered.
continue;
}
const rect = isElement ? elementRect : ancestor.getBoundingClientRect();
if ((rect.width === 0 || rect.height === 0) && elementStyle.overflow === 'hidden') {
// Zero-sized ancestors don’t make descendants hidden unless the descendant
// has ``overflow: hidden``.
return false;
}
}
return true;
}
It checks on every parent's opacity, display, and rectangle.
public static void main(String[] args){
String s1 = new String("hello");
String s2 = new String("hello");
System.out.println(s1.equals(s2));
////
System.out.println(s1 == s2);
System.out.println("-----------------------------");
String s3 = "hello";
String s4 = "hello";
System.out.println(s3.equals(s4));
////
System.out.println(s3 == s4);
}
Here in this code u can campare the both '==' and '.equals'
here .equals is used to compare the reference objects and '==' is used to compare state of objects..
Assuming you don't want to create another class, you can always let the deserializer give you a dictionary of key-value-pairs, like so:
string s = //{ "user" : { "id" : 12345, "screen_name" : "twitpicuser"}};
var serializer = new JavaScriptSerializer();
var result = serializer.DeserializeObject(s);
You'll get back something, where you can do:
var userId = int.Parse(result["user"]["id"]); // or (int)result["user"]["id"] depending on how the JSON is serialized.
// etc.
Look at result
in the debugger to see, what's in there.
GCC does actually optimize a*a*a*a*a*a
to (a*a*a)*(a*a*a)
when a is an integer. I tried with this command:
$ echo 'int f(int x) { return x*x*x*x*x*x; }' | gcc -o - -O2 -S -masm=intel -x c -
There are a lot of gcc flags but nothing fancy. They mean: Read from stdin; use O2 optimization level; output assembly language listing instead of a binary; the listing should use Intel assembly language syntax; the input is in C language (usually language is inferred from input file extension, but there is no file extension when reading from stdin); and write to stdout.
Here's the important part of the output. I've annotated it with some comments indicating what's going on in the assembly language:
; x is in edi to begin with. eax will be used as a temporary register.
mov eax, edi ; temp = x
imul eax, edi ; temp = x * temp
imul eax, edi ; temp = x * temp
imul eax, eax ; temp = temp * temp
I'm using system GCC on Linux Mint 16 Petra, an Ubuntu derivative. Here's the gcc version:
$ gcc --version
gcc (Ubuntu/Linaro 4.8.1-10ubuntu9) 4.8.1
As other posters have noted, this option is not possible in floating point, because floating point arithmetic is not associative.
One user control can't be applied to it ownself. So open another winform and the one will appear in the toolbox.
According to the great book "Effective Java":
Item 4: Enforce noninstantiability with a private constructor
- Attempting to enforce noninstantiability by making a class abstract does not work.
- A default constructor is generated only if a class contains no explicit constructors, so a class can be made noninstantiable by including a private constructor:
// Noninstantiable utility class
public class UtilityClass
{
// Suppress default constructor for noninstantiability
private UtilityClass() {
throw new AssertionError();
}
}
Because the explicit constructor is private, it is inaccessible outside of the class. The AssertionError isn’t strictly required, but it provides insurance in case the constructor is accidentally invoked from within the class. It guarantees that the class will never be instantiated under any circumstances. This idiom is mildly counterintuitive, as the constructor is provided expressly so that it cannot be invoked. It is therefore wise to include a comment, as shown above.
As a side effect, this idiom also prevents the class from being subclassed. All constructors must invoke a superclass constructor, explicitly or implicitly, and a subclass would have no accessible superclass constructor to invoke.
What is the right way to reverse a pandas DataFrame?
df[::-1]
This is objectively IMO the best method for reversing a DataFrame, because it is a ONE step operation, also very readable (assuming familiarity with slice notation).
I've found the ol' slicing trick df[::-1]
(or the equivalent df.loc[::-1]
1) to be the most concise and idiomatic way of reversing a DataFrame. This mirrors the python list reversal syntax lst[::-1]
and is clear in its intent. With the loc
syntax, you are also able to slice columns if required, so it is a bit more flexible.
Some points to consider while handling the index:
"what if I want to reverse the index as well?"
df[::-1]
reverses both the index and values."what if I want to drop the index from the result?"
.reset_index(drop=True)
at the end."what if I want to keep the index untouched (IOW, only reverse the data, not the index)?"
df[:] = df[::-1]
which creates an in-place update to df
, or df.loc[::-1].set_index(df.index)
, which returns a copy. 1: df.loc[::-1]
and df.iloc[::-1]
are equivalent since the slicing syntax remains the same, whether you're reversing by position (iloc
) or label (loc
).
X-axis represents the dataset size. Y-axis represents time taken to reverse. No method scales as well as the slicing trick, it's all the way at the bottom of the graph. Benchmarking code for reference, plots generated using perfplot.
df.reindex(index=df.index[::-1])
is clearly a popular solution, but on first glance, how obvious is it to an unfamiliar reader that this code is "reversing a DataFrame"? Additionally, this is reversing the index, then using that intermediate result to reindex
, so this is essentially a TWO step operation (when it could've been just one).
df.sort_index(ascending=False)
may work in most cases where you have a simple range index, but this assumes your index was sorted in ascending order and so doesn't generalize well.
PLEASE do not use iterrows
. I see some options suggesting iterating in reverse. Whatever your use case, there is likely a vectorized method available, but if there isn't then you can use something a little more reasonable such as list comprehensions. See How to iterate over rows in a DataFrame in Pandas for more detail on why iterrows
is an antipattern.
Could be due to the TCP protocol turned off.
How to check/enable: https://dba.stackexchange.com/questions/11377/cannot-connect-to-ms-sql-2008-r2-by-dbvisualizer-native-sspi-library-not-loade/144097#144097
Actually, I think that the answer given in the question you mentioned is just wrong (UPDATE - 20101106: someone fixed it, this answer refers to the version preceding the edit) and this explains, at least partially, why you run into troubles.
It generates two jar files in logmanager/target: logmanager-0.1.0.jar, and logmanager-0.1.0-jar-with-dependencies.jar.
The first one is the JAR of the logmanager module generated during the package
phase by jar:jar
(because the module has a packaging of type jar
). The second one is the assembly generated by assembly:assembly
and should contain the classes from the current module and its dependencies (if you used the descriptor jar-with-dependencies
).
I get an error when I double-click on the first jar:
Could not find the main class: com.gorkwobble.logmanager.LogManager. Program will exit.
If you applied the suggested configuration of the link posted as reference, you configured the jar plugin to produce an executable artifact, something like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>com.gorkwobble.logmanager.LogManager</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
So logmanager-0.1.0.jar
is indeed executable but 1. this is not what you want (because it doesn't have all dependencies) and 2. it doesn't contain com.gorkwobble.logmanager.LogManager
(this is what the error is saying, check the content of the jar).
A slightly different error when I double-click the jar-with-dependencies.jar:
Failed to load Main-Class manifest attribute from: C:\EclipseProjects\logmanager\target\logmanager-0.1.0-jar-with-dependencies.jar
Again, if you configured the assembly plugin as suggested, you have something like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
With this setup, logmanager-0.1.0-jar-with-dependencies.jar
contains the classes from the current module and its dependencies but, according to the error, its META-INF/MANIFEST.MF
doesn't contain a Main-Class
entry (its likely not the same MANIFEST.MF as in logmanager-0.1.0.jar). The jar is actually not executable, which again is not what you want.
So, my suggestion would be to remove the configuration
element from the maven-jar-plugin and to configure the maven-assembly-plugin like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.2</version>
<!-- nothing here -->
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.2-beta-4</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<archive>
<manifest>
<mainClass>org.sample.App</mainClass>
</manifest>
</archive>
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
Of course, replace org.sample.App
with the class you want to have executed. Little bonus, I've bound assembly:single
to the package
phase so you don't have to run assembly:assembly
anymore. Just run mvn install
and the assembly will be produced during the standard build.
So, please update your pom.xml with the configuration given above and run mvn clean install
. Then, cd into the target
directory and try again:
java -jar logmanager-0.1.0-jar-with-dependencies.jar
If you get an error, please update your question with it and post the content of the META-INF/MANIFEST.MF
file and the relevant part of your pom.xml
(the plugins configuration parts). Also please post the result of:
java -cp logmanager-0.1.0-jar-with-dependencies.jar com.gorkwobble.logmanager.LogManager
to demonstrate it's working fine on the command line (regardless of what eclipse is saying).
EDIT: For Java 6, you need to configure the maven-compiler-plugin. Add this to your pom.xml:

Even though the original question seems to be from 2015, this 'bug' seems to affect users installing pip-10.0.0
as well.
The workaround is not to modify pip
, however to change the way pip is called. Instead of calling /usr/bin/pip
call pip
via Python itself. For example, instead of the below:
pip install <package>
If from Python version 2 (or default Python binary is called python
) do :
python -m pip install <package>
or if from Python version 3:
python3 -m pip install <package>
h = fspecial('average', n);
filter2(h, img);
See doc fspecial
:
h = fspecial('average', n)
returns an averaging filter. n
is a 1-by-2 vector specifying the number of rows and columns in h
.
To add yet another potential solution, Helium by Clockworkmod has it's own version of ADB built in that kept being started. Exiting the Helium Desktop application resolves the issue.
As said above:
header('Content-Type: application/json');
will make the job. but keep in mind that :
Ajax will have no problem to read json even if this header is not used, except if your json contains some HTML tags. In this case you need to set the header as application/json.
Make sure your file is not encoded in UTF8-BOM. This format add a character in the top of the file, so your header() call will fail.
In Flutter the Color
class only accepts integers as parameters, or there is the possibility to use the named constructors fromARGB
and fromRGBO
.
So we only need to convert the string #b74093
to an integer value. Also we need to respect that opacity always needs to be specified.
255
(full) opacity is represented by the hexadecimal value FF
. This already leaves us with 0xFF
. Now, we just need to append our color string like this:
const color = const Color(0xffb74093); // Second `const` is optional in assignments.
The letters can by choice be capitalized or not:
const color = const Color(0xFFB74093);
Starting with Dart 2.6.0
, you can create an extension
for the Color
class that lets you use hexadecimal color strings to create a Color
object:
extension HexColor on Color {
/// String is in the format "aabbcc" or "ffaabbcc" with an optional leading "#".
static Color fromHex(String hexString) {
final buffer = StringBuffer();
if (hexString.length == 6 || hexString.length == 7) buffer.write('ff');
buffer.write(hexString.replaceFirst('#', ''));
return Color(int.parse(buffer.toString(), radix: 16));
}
/// Prefixes a hash sign if [leadingHashSign] is set to `true` (default is `true`).
String toHex({bool leadingHashSign = true}) => '${leadingHashSign ? '#' : ''}'
'${alpha.toRadixString(16).padLeft(2, '0')}'
'${red.toRadixString(16).padLeft(2, '0')}'
'${green.toRadixString(16).padLeft(2, '0')}'
'${blue.toRadixString(16).padLeft(2, '0')}';
}
The fromHex
method could also be declared in a mixin
or class
because the HexColor
name needs to be explicitly specified in order to use it, but the extension is useful for the toHex
method, which can be used implicitly. Here is an example:
void main() {
final Color color = HexColor.fromHex('#aabbcc');
print(color.toHex());
print(const Color(0xffaabbcc).toHex());
}
Many of the other answers here show how you can dynamically create a Color
from a hex string, like I did above. However, doing this means that the color cannot be a const
.
Ideally, you would assign your colors the way I explained in the first part of this answer, which is more efficient when instantiating colors a lot, which is usually the case for Flutter widgets.
Creating a .bashrc file in your home directory also works. That way you don't have to copy your .bash_profile every time you install a new version of git bash.
axios signature for post is axios.post(url[, data[, config]])
. So you want to send params object within the third argument:
.post(`/mails/users/sendVerificationMail`, null, { params: {
mail,
firstname
}})
.then(response => response.status)
.catch(err => console.warn(err));
This will POST an empty body with the two query params:
POST http://localhost:8000/api/mails/users/sendVerificationMail?mail=lol%40lol.com&firstname=myFirstName
Are you sure you need a list in this case? If you are populating the list with many items, performance will suffer with myList.Contains
or myList.Any
; the run-time will be quadratic. You might want to consider using a better data structure. For example,
public class MyClass
{
public string Property1 { get; set; }
public string Property2 { get; set; }
}
public class MyClassComparer : EqualityComparer<MyClass>
{
public override bool Equals(MyClass x, MyClass y)
{
if(x == null || y == null)
return x == y;
return x.Property1 == y.Property1 && x.Property2 == y.Property2;
}
public override int GetHashCode(MyClass obj)
{
return obj == null ? 0 : (obj.Property1.GetHashCode() ^ obj.Property2.GetHashCode());
}
}
You could use a HashSet in the following manner:
var set = new HashSet<MyClass>(new MyClassComparer());
foreach(var myClass in ...)
set.Add(myClass);
Of course, if this definition of equality for MyClass
is 'universal', you needn't write an IEqualityComparer
implementation; you could just override GetHashCode
and Equals
in the class itself.
You can do this as well. Can be faster for quick calculations:
echo $[2+2]
There is a method update
on BaseQuery object in SQLAlchemy, which is returned by filter_by
.
num_rows_updated = User.query.filter_by(username='admin').update(dict(email='[email protected]')))
db.session.commit()
The advantage of using update
over changing the entity comes when there are many objects to be updated.
If you want to give add_user
permission to all the admin
s,
rows_changed = User.query.filter_by(role='admin').update(dict(permission='add_user'))
db.session.commit()
Notice that filter_by
takes keyword arguments (use only one =
) as opposed to filter
which takes an expression.
hasOwnProperty
expects the property name as a string, so it would be shape1.hasOwnProperty("name")
execute following command from your terminal

keyCode and which represent the actual keyboard key pressed in the form of a numeric value. The reason both exist is that keyCode is available within Internet Explorer while which is available in W3C browsers like FireFox.
charCode is similar, but in this case you retrieve the Unicode value of the character pressed. For example, the letter "A."
The JavaScript expression:
var keyCode = e.keyCode ? e.keyCode : e.charCode;
Essentially says the following:
If the e.keyCode property exists, set variable keyCode to its value. Otherwise, set variable keyCode to the value of the e.charCode property.
Note that retrieving the keyCode or charCode properties typically involve figuring out differences between the event models in IE and in W3C. Some entails writing code like the following:
/*
get the event object: either window.event for IE
or the parameter e for other browsers
*/
var evt = window.event ? window.event : e;
/*
get the numeric value of the key pressed: either
event.keyCode for IE for e.which for other browsers
*/
var keyCode = evt.keyCode ? evt.keyCode : e.which;
EDIT: Corrections to my explanation of charCode as per Tor Haugen's comments.
You have to specify what encoding the data is. Either in meta or in headers
header('Content-Type: text/plain; charset=utf-8');
as noted earlier, setting bash variables does not allow whitespace between the variable name on the LHS, and the variable value on the RHS, of the '=' sign.
awk can do everything and avoid the "awk"ward extra 'grep'. The use of awk's printf is to not add an unnecessary "\n" in the string which would give perl-ish matcher programs conniptions. The variable/parameter expansion for your case in bash doesn't have that issue, so either of these work:
variable=$(ps -ef | awk '/port 10 \-/ {print $12}')
variable=`ps -ef | awk '/port 10 \-/ {print $12}'`
The '-' int the awk record matching pattern removes the need to remove awk itself from the search results.
click()
to the QMainWindow custom slot you have created).Code example:
MainWindow.h
// ...
include "newwindow.h"
// ...
public slots:
void openNewWindow();
// ...
private:
NewWindow *mMyNewWindow;
// ...
}
MainWindow.cpp
// ...
MainWindow::MainWindow()
{
// ...
connect(mMyButton, SIGNAL(click()), this, SLOT(openNewWindow()));
// ...
}
// ...
void MainWindow::openNewWindow()
{
mMyNewWindow = new NewWindow(); // Be sure to destroy your window somewhere
mMyNewWindow->show();
// ...
}
This is an example on how display a custom new window. There are a lot of ways to do this.
To keep jQuery and the DOM in sync, a simple option may be
$('#mydiv').data('myval',20).attr('data-myval',20);
So after trying all the solution, I just uninstall "One Drive" from my PC & the problem is resolved.
N.B:
<input id='r1' type='radio' class='rg' name="asdf"/>
<input id='r2' type='radio' class='rg' name="asdf"/>
<input id='r3' type='radio' class='rg' name="asdf"/>
<input id='r4' type='radio' class='rg' name="asdf"/><br/>
<input type='text' id='r1edit'/>
jquery part
$(".rg").change(function () {
if ($("#r1").attr("checked")) {
$('#r1edit:input').removeAttr('disabled');
}
else {
$('#r1edit:input').attr('disabled', 'disabled');
}
});
here is the DEMO

I was hitting this error when passing an NSURLRequest to an NSURLSession without setting the request's HTTPMethod.
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:urlComponents.URL];
Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."
Add the HTTPMethod
, though, and the connection works fine
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:urlComponents.URL];
[request setHTTPMethod:@"PUT"];
Since c++11 we could use list initialization:
char* c = new char[length]{};
For an aggregate type, then aggregate initialization will be performed, which has the same effect like char c[2] = {};
.
I followed below steps for resolution for this issue in Windows 10:
npm install -g @angular/cli@latest
C:\Users\rkota\AppData\Roaming\npm
Same path can be found by running below too:
npm config get prefix
ng --version
you will be able to see CLI version.
The StartsWith method will be faster, as there is no overhead of interpreting a regular expression, but here is how you do it:
if (Regex.IsMatch(theString, "^(mailto|ftp|joe):")) ...
The ^
mathes the start of the string. You can put any protocols between the parentheses separated by |
characters.
Another approach that is much faster, is to get the start of the string and use in a switch. The switch sets up a hash table with the strings, so it's faster than comparing all the strings:
int index = theString.IndexOf(':');
if (index != -1) {
switch (theString.Substring(0, index)) {
case "mailto":
case "ftp":
case "joe":
// do something
break;
}
}
Specify the Class Card for the constructor-:
void Card::Card(Card::Rank rank, Card::Suit suit) {
And also define the default constructor and destructor.
var numArray = [140000, 104, 99];
numArray = numArray.sort((a,b) => a-b);
alert(numArray)
num1 = num2 = 5
You can find the info here: http://www.php.net/manual/en/language.operators.comparison.php
It's scarce because it wasn't added until PHP4. What you have is fine though, if you know there may be a type difference then it's a much better comparison, since it's testing value and type in the comparison, not just value.

in -exec
without something like bash -c '... > ...'
. Though the >

anyway rather than each -exec
. +30
is older
than 30 days, -30
would be modified in last 30 days.-exec
really isn't needed, you could list everything with various -printf
options. Something like below should work
find . -type f -mtime -30 -exec ls -l {} \; > last30days.txt
Example with -printf
find . -type f -mtime -30 -printf "%M %u %g %TR %TD %p\n" > last30days.txt
This will list files in format "permissions owner group time date filename". -printf
is generally preferable to -exec
in cases where you don't have to do anything complicated. This is because it will run faster as a result of not having to execute subshells for each -exec
. Depending on the version of find
, you may also be able to use -ls
, which has a similar format to above.
I managed to work around it by reverting back to the last version that I had the mysql directory in, then deleting the contents of the directory, putting the new contents in it, and checking the new information back in. Although I'm curious if anyone has a better explanation for what the heck was going on there.
I can confirm that there is no XPath support within Beautiful Soup.

Use a white space to match all descendants of an element:
div.dropdown * {
color: red;
}
x y
matches every element y that is inside x, however deeply nested it may be - children, grandchildren and so on.
The asterisk *
matches any element.

You can't.
As a workaround you can use a // @ts-nocheck
comment at the top of a file to disable type-checking for that file: https://devblogs.microsoft.com/typescript/announcing-typescript-3-7-beta/
So to disable checking for a block (function, class, etc.), you can move it into its own file, then use the comment/flag above. (This isn't as flexible as block-based disabling of course, but it's the best option available at the moment.)
I use Google Chart Tools https://developers.google.com/chart/ It's well documented and the charts look great. Being javascript, you can feed it json data via ajax.
The syntax to store the command output into a variable is var=$(command)
.
So you can directly do:
result=$(ls -l | grep -c "rahul.*patle")
And the variable $result
will contain the number of matches.
First, you aren't actually creating 10 buttons. Second, you need to set the location of each button, or they will appear on top of each other. This will do the trick:
for (int i = 0; i < 10; ++i)
{
var button = new Button();
button.Location = new Point(button.Width * i + 4, 0);
Controls.Add(button);
}

If your <option>
elements don't have value
attributes, then you can just use .val
:
$selectElement.val("text_you're_looking_for")
However, if your <option>
elements have value attributes, or might do in future, then this won't work, because whenever possible .val
will select an option by its value
attribute instead of by its text content. There's no built-in jQuery method that will select an option by its text content if the options have value
attributes, so we'll have to add one ourselves with a simple plugin:
/*
Source: https://stackoverflow.com/a/16887276/1709587
Usage instructions:
Call
jQuery('#mySelectElement').selectOptionWithText('target_text');
to select the <option> element from within #mySelectElement whose text content
is 'target_text' (or do nothing if no such <option> element exists).
*/
jQuery.fn.selectOptionWithText = function selectOptionWithText(targetText) {
return this.each(function () {
var $selectElement, $options, $targetOption;
$selectElement = jQuery(this);
$options = $selectElement.find('option');
$targetOption = $options.filter(
function () {return jQuery(this).text() == targetText}
);
// We use `.prop` if it's available (which it should be for any jQuery
// versions above and including 1.6), and fall back on `.attr` (which
// was used for changing DOM properties in pre-1.6) otherwise.
if ($targetOption.prop) {
$targetOption.prop('selected', true);
}
else {
$targetOption.attr('selected', 'true');
}
});
}
Just include this plugin somewhere after you add jQuery onto the page, and then do
jQuery('#someSelectElement').selectOptionWithText('Some Target Text');
to select options.
The plugin method uses filter
to pick out only the option
matching the targetText, and selects it using either .attr
or .prop
, depending upon jQuery version (see .prop() vs .attr() for explanation).
Here's a JSFiddle you can use to play with all three answers given to this question, which demonstrates that this one is the only one to reliably work: http://jsfiddle.net/3cLm5/1/

A couple of issues arise when trying to reload/source ~/.profile file. [This refers to Ubuntu linux - in some cases the details of the commands will be different]
Ad. 1)
Running this directly in terminal means that there will be no subshell created. So you can use either two commands:
source ~/.bash_profile
or
. ~/.bash_profile
In both cases this will update the environment with the contents of .profile file.
Ad 2) You can start any bash script either by calling
sh myscript.sh
or
. myscript.sh
In the first case this will create a subshell that will not affect the environment variables of your system and they will be visible only to the subshell process. After finishing the subshell command none of the exports etc. will not be applied. THIS IS A COMMON MISTAKE AND CAUSES A LOT OF DEVELOPERS TO LOSE A LOT OF TIME.
In order for your changes applied in your script to have effect for the global environment the script has to be run with
.myscript.sh
command.
In order to make sure that you script is not runned in a subshel you can use this function. (Again example is for Ubuntu shell)
#/bin/bash
preventSubshell(){
if [[ $_ != $0 ]]
then
echo "Script is being sourced"
else
echo "Script is a subshell - please run the script by invoking . script.sh command";
exit 1;
fi
}
I hope this clears some of the common misunderstandings! :D Good Luck!

As explained in the openpub documentations,
pthread_exit()
will exit the thread that calls it.
In your case since the main calls it, main thread will terminate whereas your spawned threads will continue to execute. This is mostly used in cases where the main thread is only required to spawn threads and leave the threads to do their job
pthread_join
will suspend execution of the thread that has called it unless the target thread terminates
This is useful in cases when you want to wait for thread/s to terminate before further processing in main thread.
If your coordinates are stored as complex numbers you can use cmath

You can do smth like this for 1D arrays. Here we use int*& because we want our pointer to be changeable.
#include<algorithm> // for copy
void resize(int*& a, size_t& n)
{
size_t new_n = 2 * n;
int* new_a = new int[new_n];
copy(a, a + n, new_a);
delete[] a;
a = new_a;
n = new_n;
}
For 2D arrays:
#include<algorithm> // for copy
void resize(int**& a, size_t& n)
{
size_t new_n = 2 * n, i = 0;
int** new_a = new int* [new_n];
for (i = 0; i != new_n; ++i)
new_a[i] = new int[100];
for (i = 0; i != n; ++i)
{
copy(a[i], a[i] + 100, new_a[i]);
delete[] a[i];
}
delete[] a;
a = new_a;
n = new_n;
}
Invoking of 1D array:
void myfn(int*& a, size_t& n)
{
// do smth
resize(a, n);
}
Invoking of 2D array:
void myfn(int**& a, size_t& n)
{
// do smth
resize(a, n);
}
goto Mycomputer(This PC) -> rightclick ->select properties -> Advanced system settings -> environment variables-> in system variables click "New" button and write JAVA_HOME in variable name and path C:\Program Files\Java\jdk1.8.0_131 were jdk is present in variable value-> click ok.
close and reopen the command prompt after setting JAVA_HOME. Sometimes changes does not reflect in the cmd opened before setting the JAVA_HOME.
you can also set JAVA_HOME through terminal itself: SET JAVA_HOME="C:\Program Files (x86)\Java\jdk1.8.0_131"
Yes, it is possible both in Sublime Text 2 and 3 (which you should really upgrade to if you haven't already). Select View ? Ruler ? 80
(there are several other options there as well). If you like to actually wrap your text at 80 columns, select View ? Word Wrap Column ? 80
. Make sure that View ? Word Wrap
is selected.
To make your selections permanent (the default for all opened files or views), open Preferences ? Settings—User
and use any of the following rules:
{
// set vertical rulers in specified columns.
// Use "rulers": [80] for just one ruler
// default value is []
"rulers": [80, 100, 120],
// turn on word wrap for source and text
// default value is "auto", which means off for source and on for text
"word_wrap": true,
// set word wrapping at this column
// default value is 0, meaning wrapping occurs at window width
"wrap_width": 80
}
These settings can also be used in a .sublime-project
file to set defaults on a per-project basis, or in a syntax-specific .sublime-settings
file if you only want them to apply to files written in a certain language (Python.sublime-settings
vs. JavaScript.sublime-settings
, for example). Access these settings files by opening a file with the desired syntax, then selecting Preferences ? Settings—More ? Syntax Specific—User
.
As always, if you have multiple entries in your settings file, separate them with commas ,
except for after the last one. The entire content should be enclosed in curly braces { }
. Basically, make sure it's valid JSON.
If you'd like a key combo to automatically set the ruler at 80 for a particular view/file, or you are interested in learning how to set the value without using the mouse, please see my answer here.
Finally, as mentioned in another answer, you really should be using a monospace font in order for your code to line up correctly. Other types of fonts have variable-width letters, which means one 80-character line may not appear to be the same length as another 80-character line with different content, and your indentations will look all messed up. Sublime has monospace fonts set by default, but you can of course choose any one you want. Personally, I really like Liberation Mono. It has glyphs to support many different languages and Unicode characters, looks good at a variety of different sizes, and (most importantly for a programming font) clearly differentiates between 0
and O
(digit zero and capital letter oh) and 1
and l
(digit one and lowercase letter ell), which not all monospace fonts do, unfortunately. Version 2.0 and later of the font are licensed under the open-source SIL Open Font License 1.1 (here is the FAQ).
For apache-tomcat-8.5.28 version just do this,
catalina.bat jpda start
As the default settings already configured for us in catalina.bat as
if not "%JPDA_OPTS%" == "" goto gotJpdaOpts set JPDA_OPTS=-agentlib:jdwp=transport=%JPDA_TRANSPORT%,address=%JPDA_ADDRESS%,server=y,suspend=%JPDA_SUSPEND%
So no need of any other config. And when you execute command catalina.bat jpda start, you can see debug port 8000 is opened.
I'm not saying that there's anything wrong with your question or the answer given, but maybe you'd like to know about the wonderful tool that is Hoogle to save yourself time in the future: With Hoogle, you can search for standard library functions that match a given signature. So, not knowing anything about !!
, in your case you might search for "something that takes an Int
and a list of whatevers and returns a single such whatever", namely
Int -> [a] -> a
Lo and behold, with !!
as the first result (although the type signature actually has the two arguments in reverse compared to what we searched for). Neat, huh?
Also, if your code relies on indexing (instead of consuming from the front of the list), lists may in fact not be the proper data structure. For O(1) index-based access there are more efficient alternatives, such as arrays or vectors.
This is a select statement, so each branch of the case must return something. If you want to perform actions, just use an if.
To stage an entire folder, you'd enter this command:
$git add .
The period will add all files in the folder.
You can use ::after
to create a 0px
-height block after the <h4>
, which effectively moves anything after the <h4>
to the next line:
h4 {_x000D_
display: inline;_x000D_
}_x000D_
h4::after {_x000D_
content: "";_x000D_
display: block;_x000D_

Have a look at CGI in Wikipedia. CGI is a protocol between the web server and a external program or a script that handles the input and generates output that is sent to the browser.
CGI is a simply a way for web server and a program to communicate, nothing more, nothing less. Here the server manages the network connection and HTTP protocol and the program handles input and generates output that is sent to the browser. CGI script can be basically any program that can be executed by the webserver and follows the CGI protocol. Thus a CGI program can be implemented, for example, in C. However that is extremely rare, since C is not very well suited for the task.
/cgi-bin/*.cgi
is a simply a path where people commonly put their CGI script. Web server are commonly configured by default to fetch CGI scripts from that path.
a CGI script can be implemented also in PHP, but all PHP programs are not CGI scripts. If webserver has embedded PHP interpreter (e.g. mod_php in Apache), then the CGI phase is skipped by more efficient direct protocol between the web server and the interpreter.
Whether you have implemented a CGI script or not depends on how your script is being executed by the web server.
I had a problem with this. I didn't use any clever $MyInvocation
stuff to fix it though. If you open the ISE by right clicking a script file and selecting edit
then open the second script from within the ISE you can invoke one from the other by just using the normal .\script.ps1 syntax.
My guess is that the ISE has the notion of a current folder and opening it like this sets the current folder to the folder containing the scripts.
When I invoke one script from another in normal use I just use .\script.ps1, IMO it's wrong to modify the script just to make it work in the ISE properly...
mkdir -p ~/.ssh/
cat your_key > ~/.ssh/authorized_keys
cat your_key >> ~/.ssh/authorized_keys
We can prevent a thread from execution by using any of the 3 methods of Thread class:
yield()
method pauses the currently executing thread temporarily for giving a chance to the remaining waiting threads of the same priority or higher priority to execute. If there is no waiting thread or all the waiting threads have a lower priority then the same thread will continue its execution. The yielded thread when it will get the chance for execution is decided by the thread scheduler whose behavior is vendor dependent.
join()
If any executing thread t1 calls join()
on t2 (i.e. t2.join()
) immediately t1 will enter into waiting state until t2 completes its execution.
sleep()
Based on our requirement we can make a thread to be in sleeping state for a specified period of time (hope not much explanation required for our favorite method).
$ rails server -b $IP -p $PORT - that solved the same problem for me
A Queue
is an interface, which means you cannot construct a Queue
directly.
The best option is to construct off a class that already implements the Queue
interface, like one of the following: AbstractQueue
, ArrayBlockingQueue
, ArrayDeque
, ConcurrentLinkedQueue
, DelayQueue
, LinkedBlockingQueue
, LinkedList
, PriorityBlockingQueue
, PriorityQueue
, or SynchronousQueue
.
An alternative is to write your own class which implements the necessary Queue interface. It is not needed except in those rare cases where you wish to do something special while providing the rest of your program with a Queue
.
public class MyQueue<T extends Tree> implements Queue<T> {
public T element() {
... your code to return an element goes here ...
}
public boolean offer(T element) {
... your code to accept a submission offer goes here ...
}
... etc ...
}
An even less used alternative is to construct an anonymous class that implements Queue
. You probably don't want to do this, but it's listed as an option for the sake of covering all the bases.
new Queue<Tree>() {
public Tree element() {
...
};
public boolean offer(Tree element) {
...
};
...
};
window.onload
can work without body. Create page with only the script tags and open it in a browser. The page doesn't contain any body, but it still works..
<script>
function testSp()
{
alert("hit");
}
window.onload=testSp;
</script>
I'm not sure how to erase through the command line, but it's fairly easily to do it through the Keychain Access app. Just go to Applications -> Utilties -> Keychain Access, then enter "github.com". You can either delete the invalid item or update the password from with the app.
Web Applications generate 3 different types of pop-ups; namely,
1| JavaScript PopUps
2| Browser PopUps
3| Native OS PopUps [e.g., Windows Popup like Upload/Download]
In General, the JavaScript pop-ups are generated by the web application code. Selenium provides an API to handle these JavaScript pop-ups, such as Alert
.
Eventually, the simplest way to ignore Browser pop-up and download files is done by making use of Browser profiles; There are couple of ways to do this:
Before you start working with pop-ups on Browser profiles, make sure that the Download options are set default to Save File.
(Open Firefox) Tools > Options > Applications
Make use of the below snippet and do edits whenever necessary.
FirefoxProfile profile = new FirefoxProfile();
String path = "C:\\Test\\";
profile.setPreference("browser.download.folderList", 2);
profile.setPreference("browser.download.dir", path);
profile.setPreference("browser.download.manager.alertOnEXEOpen", false);
profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "application/msword, application/csv, application/ris, text/csv, image/png, application/pdf, text/html, text/plain, application/zip, application/x-zip, application/x-zip-compressed, application/download, application/octet-stream");
profile.setPreference("browser.download.manager.showWhenStarting", false);
profile.setPreference("browser.download.manager.focusWhenStarting", false);
profile.setPreference("browser.download.useDownloadDir", true);
profile.setPreference("browser.helperApps.alwaysAsk.force", false);
profile.setPreference("browser.download.manager.alertOnEXEOpen", false);
profile.setPreference("browser.download.manager.closeWhenDone", true);
profile.setPreference("browser.download.manager.showAlertOnComplete", false);
profile.setPreference("browser.download.manager.useWindow", false);
profile.setPreference("services.sync.prefs.sync.browser.download.manager.showWhenStarting", false);
profile.setPreference("pdfjs.disabled", true);
driver = new FirefoxDriver(profile);
Try this: tar -cf file.tar file-to-compress ; xz -z file.tar
Note:
|
because this runs commands simultaneously. Using ;
or &
executes commands one after another.In routes.php
, just add the following:
if (!env('ALLOW_REGISTRATION', false)) {
Route::any('/register', function() {
abort(403);
});
}
Then you can selectively control whether registration is allowed or not in you .env
file.
The quickest fix is upgrate the pip. Did worked for me:
pip install --upgrade pip
Assuming you want a grayscale image:
im = Image.new('L', (width, height))
im.putdata(an_array.flatten().tolist())
im.save("image.tiff")
Not in the submit event handler itself, no.
But what you can do is add click handlers to each submit which will inform the submit handler as to which was clicked.
Here's a full example (using jQuery for brevity)
<html>
<head>
<title>Test Page</title>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
jQuery(function($) {
var submitActor = null;
var $form = $('#test');
var $submitActors = $form.find('input[type=submit]');
$form.submit(function(event) {
if (null === submitActor) {
// If no actor is explicitly clicked, the browser will
// automatically choose the first in source-order
// so we do the same here
submitActor = $submitActors[0];
}
console.log(submitActor.name);
// alert(submitActor.name);
return false;
});
$submitActors.click(function(event) {
submitActor = this;
});
});
</script>
</head>
<body>
<form id="test">
<input type="text" />
<input type="submit" name="save" value="Save" />
<input type="submit" name="saveAndAdd" value="Save and add another" />
</form>
</body>
</html>
If you use Spring Boot, you can also enable a “debug” mode by starting your application with a --debug flag.
java -jar myapp.jar --debug
You can also specify debug=true in your application.properties.
When the debug mode is enabled, a selection of core loggers (embedded container, Hibernate, and Spring Boot) are configured to output more information. Enabling the debug mode does not configure your application to log all messages with DEBUG level.
Alternatively, you can enable a “trace” mode by starting your application with a --trace flag (or trace=true in your application.properties). Doing so enables trace logging for a selection of core loggers (embedded container, Hibernate schema generation, and the whole Spring portfolio).

Not a VIM user myself, so forgive me if this is totally offbase. But according to what I gather from the following VIM Tips site:

:verbose set history? : reveals value of history and where set
:function : list functions
:func SearchCompl : List particular function
You are trying to run bash
, an interactive shell that requires a tty in order to operate. It doesn't really make sense to run this in "detached" mode with -d
, but you can do this by adding -it
to the command line, which ensures that the container has a valid tty associated with it and that stdin
remains connected:
docker run -it -d -p 52022:22 basickarl/docker-git-test
You would more commonly run some sort of long-lived non-interactive process (like sshd
, or a web server, or a database server, or a process manager like systemd
or supervisor
) when starting detached containers.
If you are trying to run a service like sshd
, you cannot simply run service ssh start
. This will -- depending on the distribution you're running inside your container -- do one of two things:
It will try to contact a process manager like systemd
or upstart
to start the service. Because there is no service manager running, this will fail.
It will actually start sshd
, but it will be started in the background. This means that (a) the service sshd start
command exits, which means that (b) Docker considers your container to have failed, so it cleans everything up.
If you want to run just ssh in a container, consider an example like this.
If you want to run sshd
and other processes inside the container, you will need to investigate some sort of process supervisor.
For a dynamic approach, if your labels are always in front of your text areas:
$(object).prev("label").text(charsleft);
This is what I did.

if you mean an anonymous function, and are using a version of Java before Java 8, then in a word, no. (Read about lambda expressions if you use Java 8+)
However, you can implement an interface with a function like so :
Comparator<String> c = new Comparator<String>() {
int compare(String s, String s2) { ... }
};
and you can use this with inner classes to get an almost-anonymous function :)
In general:
Database and table names are not case sensitive in Windows, and case sensitive in most varieties of Unix.
In MySQL, databases correspond to directories within the data directory. Each table within a database corresponds to at least one file within the database directory. Consequently, the case sensitivity of the underlying operating system plays a part in the case sensitivity of database and table names.
One can configure how tables names are stored on the disk using the system variable lower_case_table_names
(in the my.cnf configuration file under [mysqld]).
Read the section: 10.2.2 Identifier Case Sensitivity for more information.
Use following line in didFinishLaunchingWithOptions:
delegate method:
[NSThread sleepForTimeInterval:5.0];
It will stop splash screen for 5.0 seconds.
As far as I know this isn't currently possible in C++. However, there are plans to add a feature called "concepts" in the new C++0x standard that provide the functionality that you're looking for. This Wikipedia article about C++ Concepts will explain it in more detail.
I know this doesn't fix your immediate problem but there are some C++ compilers that have already started to add features from the new standard, so it might be possible to find a compiler that has already implemented the concepts feature.
You can accomplish this using the mysqldump command-line function.
For example:
If it's an entire DB, then:
$ mysqldump -u [uname] -p db_name > db_backup.sql
If it's all DBs, then:
$ mysqldump -u [uname] -p --all-databases > all_db_backup.sql
If it's specific tables within a DB, then:
$ mysqldump -u [uname] -p db_name table1 table2 > table_backup.sql
You can even go as far as auto-compressing the output using gzip (if your DB is very big):
$ mysqldump -u [uname] -p db_name | gzip > db_backup.sql.gz
If you want to do this remotely and you have the access to the server in question, then the following would work (presuming the MySQL server is on port 3306):
$ mysqldump -P 3306 -h [ip_address] -u [uname] -p db_name > db_backup.sql
It should drop the .sql
file in the folder you run the command-line from.
EDIT: Updated to avoid inclusion of passwords in CLI commands, use the -p
option without the password. It will prompt you for it and not record it.
The restrict option is typically set to:
Here is the documentation link.
Guava has a "toString" method for reading a file into a String:
import com.google.common.base.Charsets;
import com.google.common.io.Files;
String content = Files.toString(new File("/home/x1/text.log"), Charsets.UTF_8);
This method does not require the file to be in the classpath (as in Jon Skeet previous answer).
Try to surround strings
(hoot
, story
, article
) with quotes '
:
<div ng-repeat = "data in comments">
<div ng-if="data.type == 'hoot' ">
//different template with hoot data
</div>
<div ng-if="data.type == 'story' ">
//different template with story data
</div>
<div ng-if="data.type == 'article' ">
//different template with article data
</div>
</div>
$('#id-submit').click(function () {
$("input").val(function(i,val) {
return val.toUpperCase();
});
});
the solution here worked for me : https://community.hortonworks.com/articles/4427/fix-under-replicated-blocks-in-hdfs-manually.html
su - <$hdfs_user>

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.
Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.
Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).
The registry keys of interest (At least in some versions of windows) are:
HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart
will have the value 1
if delayed, 0
if not.HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay
or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay
(on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.Whilst Cletus' answer is correct, I feel more detail should be added in regards to "evaluates to false" in JavaScript.
var title = title || 'Error';
var msg = msg || 'Error on Request';
Is not just checking if title/msg has been provided, but also if either of them are falsy. i.e. one of the following:
- false.
- 0 (zero)
- "" (empty string)
- null.
- undefined.
- NaN (a special Number value meaning Not-a-Number!)
So in the line
var title = title || 'Error';
If title is truthy (i.e., not falsy, so title = "titleMessage" etc.) then the Boolean OR (||) operator has found one 'true' value, which means it evaluates to true, so it short-circuits and returns the true value (title).
If title is falsy (i.e. one of the list above), then the Boolean OR (||) operator has found a 'false' value, and now needs to evaluate the other part of the operator, 'Error', which evaluates to true, and is hence returned.
It would also seem (after some quick firebug console experimentation) if both sides of the operator evaluate to false, it returns the second 'falsy' operator.
i.e.
return ("" || undefined)
returns undefined, this is probably to allow you to use the behavior asked about in this question when trying to default title/message to "". i.e. after running
var foo = undefined
foo = foo || ""
foo would be set to ""
You can also use this
let str = "hello single ' double \" and slash \\ yippie";
let escapeStr = escape(str);
document.write("<b>str : </b>"+str);
document.write("<br/><b>escapeStr : </b>"+escapeStr);
document.write("<br/><b>unEscapeStr : </b> "+unescape(escapeStr));

This approach works for me in Node.js, Is there any problem with this one?
File 'include.js':
fs = require('fs');
File 'main.js':
require('./include.js');
fs.readFile('./file.json', function (err, data) {
if (err) {
console.log('ERROR: file.json not found...')
} else {
contents = JSON.parse(data)
};
})
Thus your service is restarted taking care all dependencies.
What I would try in this case is put this in the stylesheet
html, body{overflow:hidden;}
this way one disables the scrollbar, and as a cumulative effect they disable scrolling with the keyboard
A package called styled-components
can solve this problem in an ELEGANT way.

@Mirek Rusin answeir is very good. But, there is small bug, and fix is requried -
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
boolean result = false;
try {
float diffY = e2.getY() - e1.getY();
float diffX = e2.getX() - e1.getX();
if (Math.abs(diffX) > Math.abs(diffY)) {
if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
if (diffX > 0) {
if (getOnSwipeListener() != null) {
getOnSwipeListener().onSwipeRight();
}
} else {
if (getOnSwipeListener() != null) {
getOnSwipeListener().onSwipeLeft();
}
}
result = true;
}
}
else if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
if (diffY > 0) {
if (getOnSwipeListener() != null) {
getOnSwipeListener().onSwipeBottom();
}
} else {
if (getOnSwipeListener() != null) {
getOnSwipeListener().onSwipeTop();
}
}
result = true;
}
What the difference? We set result = true, only if we have checked that all requrinments (both SWIPE_THRESHOLD and SWIPE_VELOCITY_THRESHOLD are Ok ). This is important if we discard swipe if some of requrinments are not achieved, and we have to do smth in onTouchEvent method of OnSwipeTouchListener!
