Another thing that people may find useful...make sure to leave off ".py" from your module name. For example, if you are trying to generate documentation for 'original' in 'original.py':
yourcode_dir$ pydoc -w original.py no Python documentation found for 'original.py' yourcode_dir$ pydoc -w original wrote original.html
I guess a little more convenient and structured way is to use Html helper. In your view it can be look like:
@{
var htmlAttr = new Dictionary<string, object>();
htmlAttr.Add("id", strElementId);
if (!CSSClass.IsEmpty())
{
htmlAttr.Add("class", strCSSClass);
}
}
@* ... *@
@Html.TextBox("somename", "", htmlAttr)
If this way will be useful for you i recommend to define dictionary htmlAttr
in your model so your view doesn't need any @{ }
logic blocks (be more clear).
The simplest solution would be to use a subquery for finding the minimum ID matching your query. In the subquery you use GROUP BY
instead of DISTINCT
:
SELECT * FROM [TestData] WHERE [ID] IN (
SELECT MIN([ID]) FROM [TestData]
WHERE [SKU] LIKE 'FOO-%'
GROUP BY [PRODUCT]
)
I faced exactly the same issue in a Spring web app. In fact, I had removed spring-security by commenting the config annotation:
// @ImportResource({"/WEB-INF/spring-security.xml"})
but I had forgotten to remove the corresponding filters in web.xml
:
<!-- Filters -->
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Commenting filters solved the issue.
Copyed the *.jar into my WEB-INF/lib folder -> Worked for me. When including over buildpath there was everytime this errormsg.
This can be achieved by putting padding between the columns using CSS. You can either add padding to the left of all columns except the first, or add padding to the right of all columns except the last. You should avoid adding padding to the right of the last column or to the left of the first as this will insert redundant white space. You should also avoid being too prescriptive with classes to specify which columns should have the additional padding as this will make maintenance harder if you later add a new column.
The 'lobotomised owl selector' allows you to select all siblings, regardless of if they are a th
, td
or something else.
tr > * + * {
padding-left: 4em;
}

New, improved answer to an old, frequently asked question...
How could I get its parent? Result should be the
store
node.
parent::
or ancestor::
axisMost answers here select the title
and then traverse up to the targeted parent or ancestor (store
) element. A simpler, direct approach is to select parent or ancestor element directly in the first place, obviating the need to traverse to a parent::
or ancestor::
axes:
//*[book/title = "50"]
Should the intervening elements vary in name:
//*[*/title = "50"]
Or, in name and depth:
//*[.//title = "50"]
setInterval(function () {document.getElementById("myButtonId").click();}, 1000);
Your code
enum Test
{
A, B
}
int a = 1;
Solution
Test castEnum = static_cast<Test>(a);
Suppose you want to display some live feed content (say livefeed.txt) on you web page without any page refresh then the following simplified example is for you.
In the below html file, the live data gets updated on the div element of id "liveData"
index.html
<!DOCTYPE html>
<html>
<head>
<title>Live Update</title>
<meta charset="UTF-8">
<script type="text/javascript" src="autoUpdate.js"></script>
</head>
<div id="liveData">
<p>Loading Data...</p>
</div>
</body>
</html>
Below autoUpdate.js reads the live data using XMLHttpRequest object and updates the html div element on every 1 second. I have given comments on most part of the code for better understanding.
autoUpdate.js
window.addEventListener('load', function()
{
var xhr = null;
getXmlHttpRequestObject = function()
{
if(!xhr)
{
// Create a new XMLHttpRequest object
xhr = new XMLHttpRequest();
}
return xhr;
};
updateLiveData = function()
{
var now = new Date();
// Date string is appended as a query with live data
// for not to use the cached version
var url = 'livefeed.txt?' + now.getTime();
xhr = getXmlHttpRequestObject();
xhr.onreadystatechange = evenHandler;
// asynchronous requests
xhr.open("GET", url, true);
// Send the request over the network
xhr.send(null);
};
updateLiveData();
function evenHandler()
{
// Check response is ready or not
if(xhr.readyState == 4 && xhr.status == 200)
{
dataDiv = document.getElementById('liveData');
// Set current data text
dataDiv.innerHTML = xhr.responseText;
// Update the live data every 1 sec
setTimeout(updateLiveData(), 1000);
}
}
});
For testing purpose: Just write some thing in the livefeed.txt - You will get updated the same in index.html without any refresh.
livefeed.txt
Hello
World
blah..
blah..
Note: You need to run the above code on the web server (ex: http://localhost:1234/index.html) not as a client html file (ex: file:///C:/index.html).
If you want the year from a (unknown) datetime-object:
tijd = datetime.datetime(9999, 12, 31, 23, 59, 59)
>>> tijd.timetuple()
time.struct_time(tm_year=9999, tm_mon=12, tm_mday=31, tm_hour=23, tm_min=59, tm_sec=59, tm_wday=4, tm_yday=365, tm_isdst=-1)
>>> tijd.timetuple().tm_year
9999
Python3:
import importlib.machinery
loader = importlib.machinery.SourceFileLoader('report', '/full/path/report/other_py_file.py')
handle = loader.load_module('report')
handle.mainFunction(parameter)
This method can be used to import whichever way you want in a folder structure (backwards, forwards doesn't really matter, i use absolute paths just to be sure).
There's also the more normal way of importing a python module in Python3,
import importlib
module = importlib.load_module('folder.filename')
module.function()
Kudos to Sebastian for spplying a similar answer for Python2:
import imp
foo = imp.load_source('module.name', '/path/to/file.py')
foo.MyClass()
What happens is when these elements are called before the DOM is loaded these kind of errors come up. Always use:
window.onload = function(){
this.keywordsInput.nativeElement.focus();
}
<script type="text/javascript">
document.getElementById('button1').onChange = function () {
document.getElementById('hidden_field_id').value = document.getElementById('span_id').innerHTML;
}
</script>
Mellen writes in a comment on a blog post:
Using Bash, there’s also ${file%.*}
to get the filename without the extension and ${file##*.}
to get the extension alone. That is,
file="thisfile.txt"
echo "filename: ${file%.*}"
echo "extension: ${file##*.}"
Outputs:
filename: thisfile
extension: txt
All of the above answers open Google Play in a new view of the same app, if you actually want to open Google Play (or any other app) independently:
Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.android.vending");
// package name and activity
ComponentName comp = new ComponentName("com.android.vending",
"com.google.android.finsky.activities.LaunchUrlHandlerActivity");
launchIntent.setComponent(comp);
// sample to open facebook app
launchIntent.setData(Uri.parse("market://details?id=com.facebook.katana"));
startActivity(launchIntent);
The important part is that actually opens google play or any other app independently.
Most of what I have seen uses the approach of the other answers and it was not what I needed hopefully this helps somebody.

Please note that the solutions based on sys.exit() or any Exception may not work in a multi-threaded environment.
Since exit() ultimately “only” raises an exception, it will only exit the process when called from the main thread, and the exception is not intercepted. (doc)
This answer from Alex Martelli for more details.
Git rebase is closer to a merge. The difference in rebase is:
So that means that all your local commits are moved to the end, after all the remote commits. If you have a merge conflict, you have to solve it too.
Just a comment on this issue. After I installed Visual Studio 2015 RTM all my resharper shortcuts were gone. (I had them working just fine with RC) A few of my colleagues were having the exact same issue with Visual Studio 2012.
I tried all the suggestions in here but none worked. The way I found to solve this was to: go to Tools -> Import and Export Settings , select the "Import selected environment settings" and in my case use the Settings I had from my RC installation (you can see that there are files with parts of a date as the filename like: CurrentSettings-2014-09-22). For my colleagues problem I basically sent them my .vssettings that I had that was working on my local VS2012 installation.
This effectively solved the shortcut problem. Further investigation in my case showed that although I applied the Resharper shortcuts they were never bound to the actual shortcut key thats why resetting stuff never worked.
Little update. There is a hook available for react-cookie
1) First of all, install the dependency (just for a note)
yarn add react-cookie
or
npm install react-cookie
2) My usage example:
// SignInComponent.js
import { useCookies } from 'react-cookie'
const SignInComponent = () => {
// ...
const [cookies, setCookie] = useCookies(['access_token', 'refresh_token'])
async function onSubmit(values) {
const response = await getOauthResponse(values);
let expires = new Date()
expires.setTime(expires.getTime() + (response.data.expires_in * 1000))
setCookie('access_token', response.data.access_token, { path: '/', expires})
setCookie('refresh_token', response.data.refresh_token, {path: '/', expires})
// ...
}
// next goes my sign-in form
}
Hope it is helpful.
Suggestions to improve the example above are very appreciated!
yes, thats possible. just use the rgba-syntax for your background-color.
.menue{
background-color: rgba(255, 0, 0, 0.5); //semi-transparent red
}
Old Answer (July 2016):
You can't directly debug Chrome for iOS due to restrictions on the published WKWebView
apps, but there are a few options already discussed in other SO threads:
If you can reproduce the issue in Safari as well, then use Remote Debugging with Safari Web Inspector. This would be the easiest approach.
WeInRe allows some simple debugging, using a simple client-server model. It's not fully featured, but it may well be enough for your problem. See instructions on set up here.
You could try and create a simple WKWebView
browser app (some instructions here), or look for an existing one on GitHub. Since Chrome uses the same rendering engine, you could debug using that, as it will be close to what Chrome produces.
There's a "bug" opened up for WebKit: Allow Web Inspector usage for release builds of WKWebView. If and when we get an API to WKWebView
, Chrome for iOS would be debuggable.
Update January 2018:
Since my answer back in 2016, some work has been done to improve things.
There is a recent project called RemoteDebug iOS WebKit Adapter, by some of the Microsoft team. It's an adapter that handles the API differences between Webkit Remote Debugging Protocol and Chrome Debugging Protocol, and this allows you to debug iOS WebViews in any app that supports the protocol - Chrome DevTools, VS Code etc.
Check out the getting started guide in the repo, which is quite detailed.
If you are interesting, you can read up on the background and architecture here.
you can also get json by using requests
as below:
import requests
r = requests.get('http://yoursite.com/your-json-pfile.json')
json_response = r.json()
Addition to @Binary Nerd
If you are using Spark, use the following to get the Spark version:
spark-submit --version
or
Login to the Cloudera Manager and goto Hosts page then run inspect hosts in cluster
An alternative way if you need something more (besides using the keys
method):
hash = {"apple" => "fruit", "carrot" => "vegetable"}
array = hash.collect {|key,value| key }
obviously you would only do that if you want to manipulate the array while retrieving it..
In Apache, you can add the woff2
mime type via your .htaccess
file as stated by this link.
AddType application/font-woff2 .woff2
In IIS, simply add the following mimeMap
tag into your web.config
file inside the staticContent
tag.
<configuration>
<system.webServer>
<staticContent>
<mimeMap fileExtension=".woff2" mimeType="application/font-woff2" />
I was having this exact problem, the above solutions didn't make much sense to me.

It only seems to because that is what it is printing out. But actually, you shouldn't write the logic this way. This is equivalent:
insert into errortable (dateupdated, table1id)
values (sysdate, 1083);
It seems silly to convert the system date to a string just to convert it back to a date.
If you want to see the full date, then you can do:
select TO_CHAR(dateupdated, 'YYYY-MM-DD HH24:MI:SS'), table1id
from errortable;
Actually, there are four forms of this operator:
<>
!=
^=
and even
¬= -- worked on some obscure platforms in the dark ages
which are the same, but treated differently when a verbatim match is required (stored outlines or cached queries).
To change the default character set and collation of a table including those of existing columns (note the convert to clause):
alter table <some_table> convert to character set utf8mb4 collate utf8mb4_unicode_ci;
Edited the answer, thanks to the prompting of some comments:
Should avoid recommending utf8. It's almost never what you want, and often leads to unexpected messes. The utf8 character set is not fully compatible with UTF-8. The utf8mb4 character set is what you want if you want UTF-8. – Rich Remer Mar 28 '18 at 23:41
and
That seems quite important, glad I read the comments and thanks @RichRemer . Nikki , I think you should edit that in your answer considering how many views this gets. See here https://dev.mysql.com/doc/refman/8.0/en/charset-unicode-utf8.html and here What is the difference between utf8mb4 and utf8 charsets in MySQL? – Paulpro Mar 12 at 17:46

I had to install setroubleshoot and setools and run the following to allow it:

sealert -a /var/log/audit/audit.log
grep crond /var/log/audit/audit.log | audit2allow -M mypol
semodule -i mypol.p
Had the exact same problem that is described herein. No matter what I did, following the above examples, to change the location of my WSDL file (in our case from a web server), it was still referencing the original location embedded within the source tree of the server process.
After MANY hours trying to debug this, I noticed that the Exception was always being thrown from the exact same line (in my case 41). Finally this morning, I decided to just send my source client code to our trade partner so they can at least understand how the code looks, but perhaps build their own. To my shock and horror I found a bunch of class files mixed in with my .java files within my client source tree. How bizarre!! I suspect these were a byproduct of the JAX-WS client builder tool.
Once I zapped those silly .class files and performed a complete clean and rebuild of the client code, everything works perfectly!! Redonculous!!
YMMV, Andrew
select 1 from table
will return a column of 1's for every row in the table. You could use it with a where statement to check whether you have an entry for a given key, as in:
if exists(select 1 from table where some_column = 'some_value')
What your friend was probably saying is instead of making bulk selects with select * from table, you should specify the columns that you need precisely, for two reasons:
1) performance & you might retrieve more data than you actually need.
2) the query's user may rely on the order of columns. If your table gets updated, the client will receive columns in a different order than expected.
For newer version of laravel:
composer create-project --prefer-dist laravel/laravel=5.5.* project_name
you can send your DateTime value into SQL as a String with its special format. this format is "yyyy-MM-dd HH:mm:ss"
Example: CurrentTime is a variable as datetime Type in SQL. And dt is a DateTime variable in .Net.
DateTime dt=DateTime.Now;
string sql = "insert into Users (CurrentTime) values (‘{0}’)";
sql = string.Format(sql, dt.ToString("yyyy-MM-dd HH:mm:ss") );
I had a similar problem and I solved in this way..
@Override
public void onCreate(Bundle savedInstanceState) {
if (getIntent().hasExtra("bundle") && savedInstanceState==null){
savedInstanceState = getIntent().getExtras().getBundle("bundle");
}
//add code for theme
switch(theme)
{
case LIGHT:
setTheme(R.style.LightTheme);
break;
case BLACK:
setTheme(R.style.BlackTheme);
break;
default:
}
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//code
}
this code is for recreate the Activity saving Bundle and changing the theme. You have to write your own onSaveInstanceState(Bundle outState); From API-11 you can use the method recreate() instead
Bundle temp_bundle = new Bundle();
onSaveInstanceState(temp_bundle);
Intent intent = new Intent(this, MainActivity.class);
intent.putExtra("bundle", temp_bundle);
startActivity(intent);
finish();
Gitlab uses GitLab Flavored Markdown (GFM)
Here "all Markdown-rendered headers automatically get IDs"
One can use mouse to :
copy and save link using right mouse click
For example in README.md file I have header:
## series expansion formula of the Boettcher function
which gives a link :
Prefix can be removed so the link here is simply
file#header
which here means:
README.md#series-expansion-formula-of-the-boettcher-function
Now it can be used as :
[series expansion formula of the Boettcher function](README.md#series-expansion-formula-of-the-boettcher-function)
One can also do it manually: replace spaces with hyphen sign.
Live example is here
row_count = $('#my_table').find('tr').length;
column_count = $('#my_table').find('td').length / row_count;
If you are looking for a custom configuration section like following
<CustomApplicationConfig>
<Credentials Username="itsme" Password="mypassword"/>
<PrimaryAgent Address="10.5.64.26" Port="3560"/>
<SecondaryAgent Address="10.5.64.7" Port="3570"/>
<Site Id="123" />
<Lanes>
<Lane Id="1" PointId="north" Direction="Entry"/>
<Lane Id="2" PointId="south" Direction="Exit"/>
</Lanes>
</CustomApplicationConfig>
then you can use my implementation of configuration section so to get started add System.Configuration
assembly reference to your project
Look at the each nested elements I used, First one is Credentials with two attributes so lets add it first
Credentials Element
public class CredentialsConfigElement : System.Configuration.ConfigurationElement
{
[ConfigurationProperty("Username")]
public string Username
{
get
{
return base["Username"] as string;
}
}
[ConfigurationProperty("Password")]
public string Password
{
get
{
return base["Password"] as string;
}
}
}
PrimaryAgent and SecondaryAgent
Both has the same attributes and seem like a Address to a set of servers for a primary and a failover, so you just need to create one element class for both of those like following
public class ServerInfoConfigElement : ConfigurationElement
{
[ConfigurationProperty("Address")]
public string Address
{
get
{
return base["Address"] as string;
}
}
[ConfigurationProperty("Port")]
public int? Port
{
get
{
return base["Port"] as int?;
}
}
}
I'll explain how to use two different element with one class later in this post, let us skip the SiteId as there is no difference in it. You just have to create one class same as above with one property only. let us see how to implement Lanes collection
it is splitted in two parts first you have to create an element implementation class then you have to create collection element class
LaneConfigElement
public class LaneConfigElement : ConfigurationElement
{
[ConfigurationProperty("Id")]
public string Id
{
get
{
return base["Id"] as string;
}
}
[ConfigurationProperty("PointId")]
public string PointId
{
get
{
return base["PointId"] as string;
}
}
[ConfigurationProperty("Direction")]
public Direction? Direction
{
get
{
return base["Direction"] as Direction?;
}
}
}
public enum Direction
{
Entry,
Exit
}
you can notice that one attribute of LanElement
is an Enumeration and if you try to use any other value in configuration which is not defined in Enumeration application will throw an System.Configuration.ConfigurationErrorsException
on startup. Ok lets move on to Collection Definition
[ConfigurationCollection(typeof(LaneConfigElement), AddItemName = "Lane", CollectionType = ConfigurationElementCollectionType.BasicMap)]
public class LaneConfigCollection : ConfigurationElementCollection
{
public LaneConfigElement this[int index]
{
get { return (LaneConfigElement)BaseGet(index); }
set
{
if (BaseGet(index) != null)
{
BaseRemoveAt(index);
}
BaseAdd(index, value);
}
}
public void Add(LaneConfigElement serviceConfig)
{
BaseAdd(serviceConfig);
}
public void Clear()
{
BaseClear();
}
protected override ConfigurationElement CreateNewElement()
{
return new LaneConfigElement();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((LaneConfigElement)element).Id;
}
public void Remove(LaneConfigElement serviceConfig)
{
BaseRemove(serviceConfig.Id);
}
public void RemoveAt(int index)
{
BaseRemoveAt(index);
}
public void Remove(String name)
{
BaseRemove(name);
}
}
you can notice that I have set the AddItemName = "Lane"
you can choose whatever you like for your collection entry item, i prefer to use "add" the default one but i changed it just for the sake of this post.
Now all of our nested Elements have been implemented now we should aggregate all of those in a class which has to implement System.Configuration.ConfigurationSection
CustomApplicationConfigSection
public class CustomApplicationConfigSection : System.Configuration.ConfigurationSection
{
private static readonly ILog log = LogManager.GetLogger(typeof(CustomApplicationConfigSection));
public const string SECTION_NAME = "CustomApplicationConfig";
[ConfigurationProperty("Credentials")]
public CredentialsConfigElement Credentials
{
get
{
return base["Credentials"] as CredentialsConfigElement;
}
}
[ConfigurationProperty("PrimaryAgent")]
public ServerInfoConfigElement PrimaryAgent
{
get
{
return base["PrimaryAgent"] as ServerInfoConfigElement;
}
}
[ConfigurationProperty("SecondaryAgent")]
public ServerInfoConfigElement SecondaryAgent
{
get
{
return base["SecondaryAgent"] as ServerInfoConfigElement;
}
}
[ConfigurationProperty("Site")]
public SiteConfigElement Site
{
get
{
return base["Site"] as SiteConfigElement;
}
}
[ConfigurationProperty("Lanes")]
public LaneConfigCollection Lanes
{
get { return base["Lanes"] as LaneConfigCollection; }
}
}
Now you can see that we have two properties with name PrimaryAgent
and SecondaryAgent
both have the same type now you can easily understand why we had only one implementation class against these two element.
Before you can use this newly invented configuration section in your app.config (or web.config) you just need to tell you application that you have invented your own configuration section and give it some respect, to do so you have to add following lines in app.config (may be right after start of root tag).
<configSections>
<section name="CustomApplicationConfig" type="MyNameSpace.CustomApplicationConfigSection, MyAssemblyName" />
</configSections>
NOTE: MyAssemblyName should be without .dll e.g. if you assembly file name is myDll.dll then use myDll instead of myDll.dll
to retrieve this configuration use following line of code any where in your application
CustomApplicationConfigSection config = System.Configuration.ConfigurationManager.GetSection(CustomApplicationConfigSection.SECTION_NAME) as CustomApplicationConfigSection;
I hope above post would help you to get started with a bit complicated kind of custom config sections.
Happy Coding :)
****Edit****
To Enable LINQ on LaneConfigCollection
you have to implement IEnumerable<LaneConfigElement>
And Add following implementation of GetEnumerator
public new IEnumerator<LaneConfigElement> GetEnumerator()
{
int count = base.Count;
for (int i = 0; i < count; i++)
{
yield return base.BaseGet(i) as LaneConfigElement;
}
}
for the people who are still confused about how yield really works read this nice article
Two key points taken from above article are
it doesn’t really end the method’s execution. yield return pauses the method execution and the next time you call it (for the next enumeration value), the method will continue to execute from the last yield return call. It sounds a bit confusing I think… (Shay Friedman)
Yield is not a feature of the .Net runtime. It is just a C# language feature which gets compiled into simple IL code by the C# compiler. (Lars Corneliussen)
you can use attribute data-html="true"
:
<a href="#" id="example" rel="popover"
data-content="<div>This <b>is</b> your div content</div>"
data-html="true" data-original-title="A Title">popover</a>
A lot of people use (click) option so I will share this too.
<button (click)="function1()" (click)="function2()">Button</button>
This will work although when embedding PHP in HTML it is better practice to use the following form:
<table>
<?php foreach($array as $key=>$value): ?>
<tr>
<td><?= $key; ?></td>
</tr>
<?php endforeach; ?>
</table>
You can find the doc for the alternative syntax on PHP.net
Here's what I did:
That's it. I have tested it with my Nokia and it's working for me.
Try using the not()
method instead of the :not()
selector.
$(".content a").click(function() {
$(".content a").not(this).hide("slow");
});
Probably a variant of the other examples, but I use this method to also make sure a dot is shown before the decimal places and not a comma:
someValue.ToString("0.00", CultureInfo.InvariantCulture)
A bit late to the party, but JQuery change inner text but preserve html has at least one approach not mentioned here:
var $td = $("#demoTable td");
$td.html($td.html().replace('Tap on APN and Enter', 'new text'));
Without fixing the text, you could use (snother)[https://stackoverflow.com/a/37828788/1587329]:
var $a = $('#demoTable td'); var inner = ''; $a.children.html().each(function() { inner = inner + this.outerHTML; }); $a.html('New text' + inner);
If you wish, you can also use the column names instead of column numbers.
For example, if you want to read data from DataGridView on the 4. row and the "Name" column. It provides me a better understanding for which variable I am dealing with.
dataGridView.Rows[4].Cells["Name"].Value.ToString();
Hope it helps.
If you are using EventBus, it as a method called hasSubscriberForEvent
which can be used to check if an Activity
is focused.
On my newer EC2 instance, simply adding the new value to the Jenkins user's .profile's PATH and then restarting tomcat worked for me.
On an older instance where the config is different, using #2 from Sagar's answer was the only thing that worked (i.e. .profile, .bash* didn't work).
IDE: The MS Office of Programming. It's where you type your code, plus some added features to make you a happier programmer. (e.g. Eclipse, Netbeans). Car body: It's what you really touch, see and work on.
Library: A library is a collection of functions, often grouped into multiple program files, but packaged into a single archive file. This contains programs created by other folks, so that you don't have to reinvent the wheel. (e.g. junit.jar, log4j.jar). A library generally has a key role, but does all of its work behind the scenes, it doesn't have a GUI. Car's engine.
API: The library publisher's documentation. This is how you should use my library. (e.g. log4j API, junit API). Car's user manual - yes, cars do come with one too!
What is a kit? It's a collection of many related items that work together to provide a specific service. When someone says medicine kit, you get everything you need for an emergency: plasters, aspirin, gauze and antiseptic, etc.
SDK: McDonald's Happy Meal. You have everything you need (and don't need) boxed neatly: main course, drink, dessert and a bonus toy. An SDK is a bunch of different software components assembled into a package, such that they're "ready-for-action" right out of the box. It often includes multiple libraries and can, but may not necessarily include plugins, API documentation, even an IDE itself. (e.g. iOS Development Kit).
Toolkit: GUI. GUI. GUI. When you hear 'toolkit' in a programming context, it will often refer to a set of libraries intended for GUI development. Since toolkits are UI-centric, they often come with plugins (or standalone IDE's) that provide screen-painting utilities. (e.g. GWT)
Framework: While not the prevalent notion, a framework can be viewed as a kit. It also has a library (or a collection of libraries that work together) that provides a specific coding structure & pattern (thus the word, framework). (e.g. Spring Framework)
In my project derived from the MVC 5 tutorial I found that changing the body padding had no effect. The following worked for me:
@media screen and (min-width:768px) and (max-width:991px) {
body {
margin-top:100px;
}
}
@media screen and (min-width:992px) and (max-width:1199px) {
body {
margin-top:50px;
}
}
It resolves the cases where the navbar folds into 2 or 3 lines. This can be inserted into bootstrap.css anywhere after the lines body { margin: 0; }

Made a simple implementation of what I believe to be what you want to achieve. You can use the class later
with the following arguments:
You can change std::chrono::milliseconds
to std::chrono::nanoseconds
or microseconds
for even higher precision and add a second int and a for loop to specify for how many times to run the code.
Here you go, enjoy:
#include <functional>
#include <chrono>
#include <future>
#include <cstdio>
class later
{
public:
template <class callable, class... arguments>
later(int after, bool async, callable&& f, arguments&&... args)
{
std::function<typename std::result_of<callable(arguments...)>::type()> task(std::bind(std::forward<callable>(f), std::forward<arguments>(args)...));
if (async)
{
std::thread([after, task]() {
std::this_thread::sleep_for(std::chrono::milliseconds(after));
task();
}).detach();
}
else
{
std::this_thread::sleep_for(std::chrono::milliseconds(after));
task();
}
}
};
void test1(void)
{
return;
}
void test2(int a)
{
printf("%i\n", a);
return;
}
int main()
{
later later_test1(1000, false, &test1);
later later_test2(1000, false, &test2, 101);
return 0;
}
Outputs after two seconds:
101
Perhaps you may want to consider doing a SELECT max(Id) - min(Id) + 1
. This will only work if your Ids are sequential and rows are not deleted. It is however very fast.
In my case, I had a problem when trying to login after restarting server, but I had csrf field in the form and I didn't refresh the page, or it kept something wrong in the cache.
This was my solution. I put this piece of code in \App\Http\Middleware\VerifyCsrfToken.php
public function handle($request, Closure $next)
{
try {
return parent::handle($request, $next); // TODO: Change the autogenerated stub
} catch(TokenMismatchException $e) {
return redirect()->back();
}
}
What it does is catching the TokenMismatchException and then redirecting the user back to the page (to reload csrf token in header and in the field). It might not work always, but it worked for my problem.
You use pip
(the Python 2 one). Now you want to upgrade pip
(the Python 3 one). After that, pip
is the Python 3 one.
Use pip2
and pip3
. This way it is explicit.
If you want to use pip
, just check where it is (which pip
) and change the link. For example:
$ which pip
/usr/local/bin/pip
$ pip --version
pip 9.0.1 from /usr/local/lib/python3.5/dist-packages (python 3.5)
$ which pip2
/usr/local/bin/pip2
$ sudo rm /usr/local/bin/pip
$ sudo ln -s /usr/local/bin/pip2 /usr/local/bin/pip
$ pip --version
pip 9.0.1 from /usr/local/lib/python2.7/dist-packages (python 2.7)

The datasource is by default .\SQLEXPRESS (its the instance where databases are placed by default) or if u changed the name of the instance during installation of sql server so i advise you to do this :
connectionString="Data Source=.\\yourInstance(defaulT Data source is SQLEXPRESS);
Initial Catalog=databaseName;
User ID=theuser if u use it;
Password=thepassword if u use it;
integrated security=true(if u don t use user and pass; else change it false)"
Without to knowing your instance, I could help with this one. Hope it helped
One advantage is for binding scenarios. Data grids and property grids will pick up the dynamic properties via the TypeDescriptor system. In addition, WPF data binding will understand dynamic properties, so WPF controls can bind to an ExpandoObject more readily than a dictionary.
Interoperability with dynamic languages, which will be expecting DLR properties rather than dictionary entries, may also be a consideration in some scenarios.
Add this class

I would like to improve the code. When you canel the aSyncTask
the onCancelled()
(callback method of aSyncTask
) gets automatically called, and there you can hide your progressBarDialog
.
You can include this code as well:
public class information extends AsyncTask<String, String, String>
{
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected String doInBackground(String... arg0) {
return null;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
this.cancel(true);
}
@Override
protected void onProgressUpdate(String... values) {
super.onProgressUpdate(values);
}
@Override
protected void onCancelled() {
Toast.makeText(getApplicationContext(), "asynctack cancelled.....", Toast.LENGTH_SHORT).show();
dialog.hide(); /*hide the progressbar dialog here...*/
super.onCancelled();
}
}
Simply,
SELECT TIME(column_name), DATE(column_name)

I think that I got a solution for this. You don't have to start monitor but you can use DDMS instead almost like in Eclipse.
Start Android Studio-> pick breakpoint-> Run-> Debug-> Go to %sdk\tools in Terminal window and run ddms.bat to run DDMS without Monitor running (since it won't let you run ADB). You can now start profiling or debug step-by-step.
Hope this helps you.

Have a look at Collections.sort()
and the Comparator
interface.
String comparison can be done with object1.getName().compareTo(object2.getName())
or object2.getName().compareTo(object1.getName())
(depending on the sort direction you desire).
If you want the sort to be case agnostic, do object1.getName().toUpperCase().compareTo(object2.getName().toUpperCase())
.
Recently I had similar problem, I solved it by importing a HTML file, the baseline example would be like this:
<html xmlns:v="urn:schemas-microsoft-com:vml"
xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"
xmlns="http://www.w3.org/TR/REC-html40">
<head>
<style>
<!--
br {mso-data-placement:same-cell;}
-->
</style>
</head>
<body>
<table>
<tr>
<td>first line<br/>second line</td>
<td style="white-space:normal">first line<br/>second line</td>
</tr>
</table>
</body>
</html>
I know, it is not a CSV, and might work differently for various versions of Excel, but I think it is worth a try.
I hope this helps ;-)
This may work:
nvm install NEW_VERSION --reinstall-packages-from=OLD_VERSION
For example:
nvm install 6.7 --reinstall-packages-from=6.4
then, if you want, you can delete your previous version with:
nvm uninstall OLD_VERSION
Where, in your case, NEW_VERSION = 5.4 OLD_VERSION = 5.0
Alternatively, try:
nvm install stable --reinstall-packages-from=current

The simple answer for this one is that you have an undeclared (null) variable. In this case it is $md5
. From the comment you put this needed to be declared elsewhere in your code
$md5 = new-object -TypeName System.Security.Cryptography.MD5CryptoServiceProvider
The error was because you are trying to execute a method that does not exist.
PS C:\Users\Matt> $md5 | gm
TypeName: System.Security.Cryptography.MD5CryptoServiceProvider
Name MemberType Definition
---- ---------- ----------
Clear Method void Clear()
ComputeHash Method byte[] ComputeHash(System.IO.Stream inputStream), byte[] ComputeHash(byte[] buffer), byte[] ComputeHash(byte[] buffer, int offset, ...
The .ComputeHash()
of $md5.ComputeHash()
was the null valued expression. Typing in gibberish would create the same effect.
PS C:\Users\Matt> $bagel.MakeMeABagel()
You cannot call a method on a null-valued expression.

It is not possible to dynamically change the value of a file field, otherwise you could set it to "c:\yourfile" and steal files very easily.
However there are many solutions to a multi-upload system. I'm guessing that you're wanting to have a multi-select open dialog.
Perhaps have a look at http://www.plupload.com/ - it's a very flexible solution to multiple file uploads, and supports drop zones e.t.c.
1.redirect return the request to the browser from server,then resend the request to the server from browser.
2.forward send the request to another servlet (servlet to servlet).

Gilean's answer is great, but I just wanted to add that sometimes there are rare exceptions to best practices, and you might want to test your environment both ways to see what will work best.
In one case, I found that query
worked faster for my purposes because I was bulk transferring trusted data from an Ubuntu Linux box running PHP7 with the poorly supported Microsoft ODBC driver for MS SQL Server.
I arrived at this question because I had a long running script for an ETL that I was trying to squeeze for speed. It seemed intuitive to me that query
could be faster than prepare
& execute
because it was calling only one function instead of two. The parameter binding operation provides excellent protection, but it might be expensive and possibly avoided if unnecessary.
Given a couple rare conditions:
If you can't reuse a prepared statement because it's not supported by the Microsoft ODBC driver.
If you're not worried about sanitizing input and simple escaping is acceptable. This may be the case because binding certain datatypes isn't supported by the Microsoft ODBC driver.
PDO::lastInsertId
is not supported by the Microsoft ODBC driver.
Here's a method I used to test my environment, and hopefully you can replicate it or something better in yours:
To start, I've created a basic table in Microsoft SQL Server
CREATE TABLE performancetest (
sid INT IDENTITY PRIMARY KEY,
id INT,
val VARCHAR(100)
);
And now a basic timed test for performance metrics.
$logs = [];
$test = function (String $type, Int $count = 3000) use ($pdo, &$logs) {
$start = microtime(true);
$i = 0;
while ($i < $count) {
$sql = "INSERT INTO performancetest (id, val) OUTPUT INSERTED.sid VALUES ($i,'value $i')";
if ($type === 'query') {
$smt = $pdo->query($sql);
} else {
$smt = $pdo->prepare($sql);
$smt ->execute();
}
$sid = $smt->fetch(PDO::FETCH_ASSOC)['sid'];
$i++;
}
$total = (microtime(true) - $start);
$logs[$type] []= $total;
echo "$total $type\n";
};
$trials = 15;
$i = 0;
while ($i < $trials) {
if (random_int(0,1) === 0) {
$test('query');
} else {
$test('prepare');
}
$i++;
}
foreach ($logs as $type => $log) {
$total = 0;
foreach ($log as $record) {
$total += $record;
}
$count = count($log);
echo "($count) $type Average: ".$total/$count.PHP_EOL;
}
I've played with multiple different trial and counts in my specific environment, and consistently get between 20-30% faster results with query
than prepare
/execute
5.8128969669342 prepare
5.8688418865204 prepare

I'm curious to see how this test compares in other environments, like MySQL.
You can say:
we can't instantiate an abstract class, but we can use new

as implement body at the the end of the abstract class.
Quite late to this party, today I had the same problem.
The right answer on macOs I think is use jenv
brew install jenv openjdk@11
jenv add /usr/local/opt/openjdk@11
And then add into Intellij IDEA as new SDK the following path:
~/.jenv/versions/11/libexec/openjdk.jdk/Contents/Home/
The most simple and shortest way to accomplish this:
/[^\p{L}\d\s@#]/u
[^...]
Match a single character not present in the list below
\p{L}
=> matches any kind of letter from any language
\d
=> matches a digit zero through nine
\s
=> matches any kind of invisible character
@#
=> @
and #
characters
Don't forget to pass the u
(unicode) flag.
I may be late, but you can try the following code, which worked for me for Drag and Drop.
.dndclass{
cursor: url('../images/grab1.png'), auto;
}
.dndclass:active {
cursor: url('../images/grabbing1.png'), auto;
}
You can use the images below in the URL above. Make sure it is a PNG transparent image. If not, download one from google.
If i understand your question you want to have the overlay just over the image and not cover everything?
I'd set the parent DIV (i renamed in content in the jsfiddle) position to relative, as the overlay should be positioned relative to this div not the window.
.content
{
position: relative;
}
I did some pocking around and updated your fiddle to just have the overlay sized to the img which (I think) is what you want, let me know anyway :) http://jsfiddle.net/b9Vyw/
Here's a simple trap that prints the last argument of whatever failed to STDERR, reports the line it failed on, and exits the script with the line number as the exit code. Note these are not always great ideas, but this demonstrates some creative application you could build on.
trap 'echo >&2 "$_ at $LINENO"; exit $LINENO;' ERR
I put that in a script with a loop to test it. I just check for a hit on some random numbers; you might use actual tests. If I need to bail, I call false (which triggers the trap) with the message I want to throw.
For elaborated functionality, have the trap call a processing function. You can always use a case statement on your arg ($_) if you need to do more cleanup, etc. Assign to a var for a little syntactic sugar -
trap 'echo >&2 "$_ at $LINENO"; exit $LINENO;' ERR
throw=false
raise=false
while :
do x=$(( $RANDOM % 10 ))
case "$x" in
0) $throw "DIVISION BY ZERO" ;;
3) $raise "MAGIC NUMBER" ;;
*) echo got $x ;;
esac
done
Sample output:
# bash tst
got 2
got 8
DIVISION BY ZERO at 6
# echo $?
6
Obviously, you could
runTest1 "Test1 fails" # message not used if it succeeds
Lots of room for design improvement.
The draw backs include the fact that false
isn't pretty (thus the sugar), and other things tripping the trap might look a little stupid. Still, I like this method.
Didn't find the voted solutions satisfactory. So I wrote something thats is kind of generic and works both first and last part of your text (something like substr but for words). Also you can set if you'd like the spaces to be left out in the char-count.
function chopTxtMinMax(txt, firstChar, lastChar=0){
var wordsArr = txt.split(" ");
var newWordsArr = [];
var totalIteratedChars = 0;
var inclSpacesCount = true;
for(var wordIndx in wordsArr){
totalIteratedChars += wordsArr[wordIndx].length + (inclSpacesCount ? 1 : 0);
if(totalIteratedChars >= firstChar && (totalIteratedChars <= lastChar || lastChar==0)){
newWordsArr.push(wordsArr[wordIndx]);
}
}
txt = newWordsArr.join(" ");
return txt;
}

In Simple one liner for deleting null values in Hash,
rec_hash.each {|key,value| rec_hash.delete(key) if value.blank? }
Right click on the project. Go to properties. Click on Run/Debug Settings. Now delete the run config of your main class that you are trying to run. Now, when you hit run again, things would work just fine.
Not really interactive shell tricks, but valid nonetheless as tricks for writing good scripts.
getopts, shift, $OPTIND, $OPTARG:
I love making customizable scripts:
while getopts 'vo:' flag; do
case "$flag" in
'v')
VERBOSE=1
;;
'o')
OUT="$OPTARG"
;;
esac
done
shift "$((OPTIND-1))"
xargs(1):
I have a triple-core processor and like to run scripts that perform compression, or some other CPU-intensive serial operation on a set of files. I like to speed it up using xargs
as a job queue.
if [ "$#" -gt 1 ]; then
# schedule using xargs
(for file; do
echo -n "$file"
echo -ne '\0'
done) |xargs -0 -n 1 -P "$NUM_JOBS" -- "$0"
else
# do the actual processing
fi
This acts a lot like make -j [NUM_JOBS]
.
I think this may help you solve your issue.
Imagine you have a dictionary like this:
dic0 = {0:"CL1", 1:"CL2", 2:"CL3"}
And you want to change values by this one:
dic0to1 = {"CL1":"Unknown1", "CL2":"Unknown2", "CL3":"Unknown3"}
You can use code bellow to change values of dic0
properly respected to dic0t01
without worrying yourself about indexes in dictionary:
for x, y in dic0.items():
dic0[x] = dic0to1[y]
Now you have:
>>> dic0
{0: 'Unknown1', 1: 'Unknown2', 2: 'Unknown3'}
It's not a good idea to uninstall 1.8.6 if it's in /usr/bin
. That is owned by the OS and is expected to be there.
If you put /usr/local/bin
in your PATH before /usr/bin
then things you have installed in /usr/local/bin
will be found before any with the same name in /usr/bin
, effectively overwriting or updating them, without actually doing so. You can still reach them by explicitly using /usr/bin
in your #! interpreter invocation line at the top of your code.
@Anurag recommended using RVM, which I'll second. I use it to manage 1.8.7 and 1.9.1 in addition to the OS's 1.8.6.
sudo su
cd /var/log/mysql
and lastly type: > mysql-slow.log

For people who find this when attempting to run tests because via npm test
or ng test
using Karma or whatever else. Your .spec module needs a special router testing import to be able to build.
import { RouterTestingModule } from '@angular/router/testing';
TestBed.configureTestingModule({
imports: [RouterTestingModule],
declarations: [AppComponent],
});

An extension to Dilums's answer:
Without changing code, you likely need pursue custom implementations of URL related interfaces as Dilum recommends. To simplify things for you, I can recommend looking at the source for Spring Framework's Resources. While the code is not in the form of a stream handler, it has been designed to do exactly what you are looking to do and is under the ASL 2.0 license, making it friendly enough for re-use in your code with due credit.
Use a pattern along these lines:
function getValue(file) {
return lookupValue(file);
}
getValue('myFile.txt').then(function(res) {
// do whatever with res here
});
(although this is a bit redundant, I'm sure your actual code is more complicated)

However there is other ways to do it and nowdays i would prefer using CSS stylesheets. There is also w3c tutorials for beginners.
With CSS you can do it like this:

<title>CSS test</title>
<style type="text/css">
p { word-spacing: 40px; }
</style>
</head>
<body>
<p>Hello World! Enough space between words, what do you think about it?</p>
</body>
</html>
Follow these steps:

In order to log all the requests with input parameters and body, we can use filters and interceptors. But while using a filter or interceptor, we cannot print the request body multiple times. The better way is we can use spring-AOP. By using this we can decouple the logging mechanism from the application. AOP can be used for logging Input and output of each method in the application.

.IMG files are ususally filesystems, not pictures. The easiest way to access them is to install VMWare, install Windows in VMWare, and then add the .img file as some kind of disk device (floppy, cdrom, hard disk). If you guess the right kind, Windows might be able to open it.
Based on all the above I suggest a slightly modified version (python3):
None
Code:
import subprocess
proc = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE,
stderr=subprocess.STDOUT, universal_newlines=True)
while True:
rd = proc.stdout.readline()
print(rd, end='') # and whatever you want to do...
if not rd: # EOF
returncode = proc.poll()
if returncode is not None:
break
time.sleep(0.1) # cmd closed stdout, but not exited yet
# You may want to check on ReturnCode here
In my situation Adobe was using the same port. After stopping the Adobe Creative Cloud Desktop process, VS functioned as expected.
Cloning the objects before adding them. For example, instead of newList.addAll(oldList);

OK it's 2019 now, and from Java 11 you have a constructor with Charset:
FileWriter?(String fileName, Charset charset)
Unfortunately, we still cannot modify the byte buffer size, and it's set to 8192. (https://www.baeldung.com/java-filewriter)
Final working solution:
public static String getFileName(Uri uri) {
try {
String path = uri.getLastPathSegment();
return path != null ? path.substring(path.lastIndexOf("/") + 1) : "unknown";
} catch (Exception e) {
e.printStackTrace();
}
return "unknown";
}
You have to use ==
to compare (or even ===
, if you want to compare types). A single =
is for assignment.
if (one == 'rock' && two == 'rock') {
console.log('Tie! Try again!');
}
The conditional or operator is ||:
if (expr1 || expr2) {do stuff}
if (title == "User greeting" || title == "User name") {do stuff}
The conditional (the OR) and it's parts are boolean expressions.
MSDN lists the C# operators in precedence order here http://msdn.microsoft.com/en-us/library/6a71f45d.aspx . And the MSDN page for boolean expressions is http://msdn.microsoft.com/en-us/library/dya2szfk.aspx .
If you are just starting to learn programming, you should read up on Conditional Statements from an introductory text or tutorial. This one seems to cover most of the basics: http://www.functionx.com/csharp/Lesson10.htm .
Just in case it helps someone, here's what caused this error for me: I needed a procedure to return json but I left out the for json path:
set @jsonout = (SELECT ID, SumLev, Census_GEOID, AreaName, Worksite
from CS_GEO G (nolock)
join @allids a on g.ID = a.[value]
where g.Worksite = @worksite)
When I tried to save the stored procedure, it threw the error. I fixed it by adding for json path to the code at the end of the procedure:
set @jsonout = (SELECT ID, SumLev, Census_GEOID, AreaName, Worksite
from CS_GEO G (nolock)
join @allids a on g.ID = a.[value]
where g.Worksite = @worksite for json path)
I found this problem too. Because centos service depend on multi-user.target for none desktop Cenots 7.2. so I delete multi-user.target from my .service file. It had missed.
There are several ways to do it. The subplots
method creates the figure along with the subplots that are then stored in the ax
array. For example:
import matplotlib.pyplot as plt
x = range(10)
y = range(10)
fig, ax = plt.subplots(nrows=2, ncols=2)
for row in ax:
for col in row:
col.plot(x, y)
plt.show()
However, something like this will also work, it's not so "clean" though since you are creating a figure with subplots and then add on top of them:
fig = plt.figure()
plt.subplot(2, 2, 1)
plt.plot(x, y)
plt.subplot(2, 2, 2)
plt.plot(x, y)
plt.subplot(2, 2, 3)
plt.plot(x, y)
plt.subplot(2, 2, 4)
plt.plot(x, y)
plt.show()
The best and better way is to create an element and append it to the body
tag.
Second way is to first get the innerHTML
property of body
and add code with it. For example:
var b = document.getElementsByTagName('body');
b.innerHTML = b.innerHTML + "Your code";
<script>
$(document).ready(function(){
$('#connectBtn').click(function(e){
e.preventDefault();
})
});
</script>
This will prevent the default action.
Looks like you're trying to execute a windows file (.exe) Surely you ought to be using powershell. Anyway on a Linux bash shell a simple one-liner will suffice.
[/home/$] for filename in /Data/*.txt; do for i in {0..3}; do ./MyProgam.exe Data/filenameLogs/$filename_log$i.txt; done done
Or in a bash
#!/bin/bash
for filename in /Data/*.txt;
do
for i in {0..3};
do ./MyProgam.exe Data/filename.txt Logs/$filename_log$i.txt;
done
done
As others have said, Objective-C is much more dynamic in terms of how it thinks of objects vs. C++'s fairly static realm.
Objective-C, being in the Smalltalk lineage of object-oriented languages, has a concept of objects that is very similar to that of Java, Python, and other "standard", non-C++ object-oriented languages. Lots of dynamic dispatch, no operator overloading, send messages around.
C++ is its own weird animal; it mostly skipped the Smalltalk portion of the family tree. In some ways, it has a good module system with support for inheritance that happens to be able to be used for object-oriented programming. Things are much more static (overridable methods are not the default, for example).
This is caused because all the changes to the RemoteViews are serialised (e.g. setInt and setImageViewBitmap ). The bitmaps are also serialised into an internal bundle. Unfortunately this bundle has a very small size limit.
You can solve it by scaling down the image size this way:
public static Bitmap scaleDownBitmap(Bitmap photo, int newHeight, Context context) {
final float densityMultiplier = context.getResources().getDisplayMetrics().density;
int h= (int) (newHeight*densityMultiplier);
int w= (int) (h * photo.getWidth()/((double) photo.getHeight()));
photo=Bitmap.createScaledBitmap(photo, w, h, true);
return photo;
}
Choose newHeight to be small enough (~100 for every square it should take on the screen) and use it for your widget, and your problem will be solved :)
Use this simple code for DataTables custom sorting. Its 100% work
<script>
$(document).ready(function() {
$('#myTable').DataTable( {
"order": [[ 0, "desc" ]] // "0" means First column and "desc" is order type;
} );
} );
</script>
See in Datatables website
https://datatables.net/examples/basic_init/table_sorting.html
If that div
is the only thing on your page, set:
body, html {
height: 100%;
width: 100%;
}
You can use:
for (int x = 0; x < 10; x++) {
if (x == 5) { // If x is 5, then break it.
break;
}
}
The curly braces inside backgroundImage property are wrong.
Probably you are using webpack along with image files loader, so Background should be already a String:
backgroundImage: "url(" + Background + ")"
You can also use ES6 string templates as below to achieve the same effect:
backgroundImage: `url(${Background})`
Player.cpp
require the definition of Ball
class. So simply add #include "Ball.h"
Player.cpp:
#include "Player.h"
#include "Ball.h"
void Player::doSomething(Ball& ball) {
ball.ballPosX += 10; // incomplete type error occurs here.
}
The simplest answer, assuming you don't mind the vagaries and variations in format between different platforms, is the standard %p
notation.
The C99 standard (ISO/IEC 9899:1999) says in §7.19.6.1 ¶8:
p
The argument shall be a pointer tovoid
. The value of the pointer is converted to a sequence of printing characters, in an implementation-defined manner.
(In C11 — ISO/IEC 9899:2011 — the information is in §7.21.6.1 ¶8.)
On some platforms, that will include a leading 0x
and on others it won't, and the letters could be in lower-case or upper-case, and the C standard doesn't even define that it shall be hexadecimal output though I know of no implementation where it is not.
It is somewhat open to debate whether you should explicitly convert the pointers with a (void *)
cast. It is being explicit, which is usually good (so it is what I do), and the standard says 'the argument shall be a pointer to void
'. On most machines, you would get away with omitting an explicit cast. However, it would matter on a machine where the bit representation of a char *
address for a given memory location is different from the 'anything else pointer' address for the same memory location. This would be a word-addressed, instead of byte-addressed, machine. Such machines are not common (probably not available) these days, but the first machine I worked on after university was one such (ICL Perq).
If you aren't happy with the implementation-defined behaviour of %p
, then use C99 <inttypes.h>
and uintptr_t
instead:
printf("0x%" PRIXPTR "\n", (uintptr_t)your_pointer);
This allows you to fine-tune the representation to suit yourself. I chose to have the hex digits in upper-case so that the number is uniformly the same height and the characteristic dip at the start of 0xA1B2CDEF
appears thus, not like 0xa1b2cdef
which dips up and down along the number too. Your choice though, within very broad limits. The (uintptr_t)
cast is unambiguously recommended by GCC when it can read the format string at compile time. I think it is correct to request the cast, though I'm sure there are some who would ignore the warning and get away with it most of the time.
Kerrek asks in the comments:
I'm a bit confused about standard promotions and variadic arguments. Do all pointers get standard-promoted to void*? Otherwise, if
int*
were, say, two bytes, andvoid*
were 4 bytes, then it'd clearly be an error to read four bytes from the argument, non?
I was under the illusion that the C standard says that all object pointers must be the same size, so void *
and int *
cannot be different sizes. However, what I think is the relevant section of the C99 standard is not so emphatic (though I don't know of an implementation where what I suggested is true is actually false):
§6.2.5 Types
¶26 A pointer to void shall have the same representation and alignment requirements as a pointer to a character type.39) Similarly, pointers to qualified or unqualified versions of compatible types shall have the same representation and alignment requirements. All pointers to structure types shall have the same representation and alignment requirements as each other. All pointers to union types shall have the same representation and alignment requirements as each other. Pointers to other types need not have the same representation or alignment requirements.
39) The same representation and alignment requirements are meant to imply interchangeability as arguments to functions, return values from functions, and members of unions.
(C11 says exactly the same in the section §6.2.5, ¶28, and footnote 48.)
So, all pointers to structures must be the same size as each other, and must share the same alignment requirements, even though the structures the pointers point at may have different alignment requirements. Similarly for unions. Character pointers and void pointers must have the same size and alignment requirements. Pointers to variations on int
(meaning unsigned int
and signed int
) must have the same size and alignment requirements as each other; similarly for other types. But the C standard doesn't formally say that sizeof(int *) == sizeof(void *)
. Oh well, SO is good for making you inspect your assumptions.
The C standard definitively does not require function pointers to be the same size as object pointers. That was necessary not to break the different memory models on DOS-like systems. There you could have 16-bit data pointers but 32-bit function pointers, or vice versa. This is why the C standard does not mandate that function pointers can be converted to object pointers and vice versa.
Fortunately (for programmers targetting POSIX), POSIX steps into the breach and does mandate that function pointers and data pointers are the same size:
§2.12.3 Pointer Types
All function pointer types shall have the same representation as the type pointer to void. Conversion of a function pointer to
void *
shall not alter the representation. Avoid *
value resulting from such a conversion can be converted back to the original function pointer type, using an explicit cast, without loss of information.Note: The ISO C standard does not require this, but it is required for POSIX conformance.
So, it does seem that explicit casts to void *
are strongly advisable for maximum reliability in the code when passing a pointer to a variadic function such as printf()
. On POSIX systems, it is safe to cast a function pointer to a void pointer for printing. On other systems, it is not necessarily safe to do that, nor is it necessarily safe to pass pointers other than void *
without a cast.
What i have also noticed is that you have to save the file as Unicode
, UTF-8
, no BOM
in an Windows format with CRLF
(Carriage Return, Line Feed). Because if you don't, the import will break. (Saying something about weird chars in the file)
Good luck :) Sid
I think natually do it is straightforward, whether Intellij IDEA or Android Studio, I always click new Java class menu, and then typing the class name, press Enter to create. after that, I manually typing "extends Activity" in the class file, and then import the class by shortcut key. finally, I also manually override the onCreate() method and invoke the setContentView() method.
Simple solution is:
public String frontBack(String str) {
if (str == null || str.length() == 0) {
return str;
}
char[] cs = str.toCharArray();
char first = cs[0];
cs[0] = cs[cs.length -1];
cs[cs.length -1] = first;
return new String(cs);
}
Using a character array (watch out for the nasty empty String or null String argument!)
Another solution uses StringBuilder (which is usually used to do String manupilation since String itself is immutable.
public String frontBack(String str) {
if (str == null || str.length() == 0) {
return str;
}
StringBuilder sb = new StringBuilder(str);
char first = sb.charAt(0);
sb.setCharAt(0, sb.charAt(sb.length()-1));
sb.setCharAt(sb.length()-1, first);
return sb.toString();
}
Yet another approach (more for instruction than actual use) is this one:
public String frontBack(String str) {
if (str == null || str.length() < 2) {
return str;
}
StringBuilder sb = new StringBuilder(str);
String sub = sb.substring(1, sb.length() -1);
return sb.reverse().replace(1, sb.length() -1, sub).toString();
}
Here the complete string is reversed and then the part that should not be reversed is replaced with the substring. ;)
Programmatically with the CUDA Runtime API C++ wrappers:
auto v1 = cuda::version::maximum_supported_by_driver();
auto v2 = cuda::version::runtime();
This gives you a cuda::version_t
structure, which you can compare and also stream, e.g.:
if (v2 < cuda::version_t{ 8, 0 } ) {
std::cerr << "CUDA version " << v2 << " is insufficient." std::endl;
}
This is because your servlet is trying to access a request object which is no more exist.. A servlet's forward or include statement does not stop execution of method block. It continues to the end of method block or first return statement just like any other java method.
The best way to resolve this problem just set the page (where you suppose to forward the request) dynamically according your logic. That is:
protected void doPost(request , response){
String returnPage="default.jsp";
if(condition1){
returnPage="page1.jsp";
}
if(condition2){
returnPage="page2.jsp";
}
request.getRequestDispatcher(returnPage).forward(request,response); //at last line
}
and do the forward only once at last line...
you can also fix this problem using return statement after each forward() or put each forward() in if...else block

As mentioned above, a[::-1]
really only creates a view, so it's a constant-time operation (and as such doesn't take longer as the array grows). If you need the array to be contiguous (for example because you're performing many vector operations with it), ascontiguousarray
is about as fast as flipud
/fliplr
:

lambda a: numpy.ascontiguousarray(a[::-1]),
lambda a: numpy.fliplr([a])[0],
],

Java objects reside in an area called the heap, while metadata such as class objects and method objects reside in the permanent generation or Perm Gen area. The permanent generation is not part of the heap.
The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected. During the garbage collection objects that are no longer used are cleared, thus making space for new objects.
-Xmssize Specifies the initial heap size.
-Xmxsize Specifies the maximum heap size.
-XX:MaxPermSize=size Sets the maximum permanent generation space size. This option was deprecated in JDK 8, and superseded by the -XX:MaxMetaspaceSize option.
Sizes are expressed in bytes. Append the letter k
or K
to indicate kilobytes, m
or M
to indicate megabytes, g
or G
to indicate gigabytes.

It's called dependency injection via constructor injection: class A
gets the dependency as an argument to its constructor and saves the reference to dependent class as a private variable.
There's an interesting introduction on wikipedia.
For const-correctness I'd write:
using T = int;
class A
{
public:
A(const T &thing) : m_thing(thing) {}
// ...
private:
const T &m_thing;
};
but a problem with this class is that it accepts references to temporary objects:
T t;
A a1{t}; // this is ok, but...
A a2{T()}; // ... this is BAD.
It's better to add (requires C++11 at least):
class A
{
public:
A(const T &thing) : m_thing(thing) {}
A(const T &&) = delete; // prevents rvalue binding
// ...
private:
const T &m_thing;
};
Anyway if you change the constructor:
class A
{
public:
A(const T *thing) : m_thing(*thing) { assert(thing); }
// ...
private:
const T &m_thing;
};
it's pretty much guaranteed that you won't have a pointer to a temporary.
Also, since the constructor takes a pointer, it's clearer to users of A
that they need to pay attention to the lifetime of the object they pass.

This is an old question but alot of the answers in here use VB or VBA. The tag says vbscript (which is how I got here).
The answers here got kind of muddled since VB is super broad where you can have so many applications of it. My answer is solely on vbscript and accomplishes my case of formatting in YYYYMMDD in vbscript
Sharing what I've learned:
DateTime
functions in vbscript defined here so you can mix-n-match to get the result that you wantYYYYMMDD
to do that I just needed to concat DatePart
like so for the current Date: date = DatePart("yyyy",Date) & DatePart("m",Date) & DatePart("d",Date)
That's all, I hope this helps someone.
A binary search tree uses the definition: that for every node,the node to the left of it has a less value(key) and the node to the right of it has a greater value(key).
Where as the heap,being an implementation of a binary tree uses the following definition:
If A and B are nodes, where B is the child node of A,then the value(key) of A must be larger than or equal to the value(key) of B.That is, key(A) = key(B).

I've done all things above but my problem did not solve (trying to open project by VS 2017),
after that I realized that the problem was my csproj file. My project (mvc)
was created by VS 2015... So I edit my csproj file and replace
<Import Project="..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props" Condition="Exists('..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props')" />
by this :
<Import Project="..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.7\build\net45\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props" Condition="Exists('..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.7\build\net45\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props')" />
It was all about the version of DotNetCompilerPlatform.
(the way that I understood this issue was that I created new mvc project by VS 2017 and compared both csproj files - the new one and the one that created by VS 2015 - )
Additional related info by https://stackoverflow.com/users/15667/xan (since answers are locked)
For me (VS2019 opening an older solution) it was only affecting one project in the solution. The Imports looked like this:
<Import Project="..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props" Condition="Exists('..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props')" />
<Import Project="..\packages\Microsoft.Net.Compilers.1.0.0\build\Microsoft.Net.Compilers.props" Condition="Exists('..\packages\Microsoft.Net.Compilers.1.0.0\build\Microsoft.Net.Compilers.props')" />
<Import Project="$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props" Condition="Exists('$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props')" />
The working projects only had the
<Import Project="$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props" Condition="Exists('$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props')" />
line, so I removed the first 2 and intelisense / go to definition etc. started working again.
HOWEVER the web project now wouldn't run due to missing Roslyn csc compiler.
In the end the solution that worked overall was to update the Microsoft.CodeDom.Providers.DotNetCompilerPlatform

Nuget packages for the project.
You can use either one of these to check null, whitespace and empty strings.
WHERE COLUMN <> ''
WHERE LEN(COLUMN) > 0
WHERE NULLIF(LTRIM(RTRIM(COLUMN)), '') IS NOT NULL
(4castle's answer is better than the below if you can assume Java >= 9)
You need to create a matcher and use that to iteratively find matches.
import java.util.regex.Matcher;
import java.util.regex.Pattern;
...
List<String> allMatches = new ArrayList<String>();
Matcher m = Pattern.compile("your regular expression here")
.matcher(yourStringHere);
while (m.find()) {
allMatches.add(m.group());
}
After this, allMatches
contains the matches, and you can use allMatches.toArray(new String[0])
to get an array if you really need one.
You can also use MatchResult
to write helper functions to loop over matches
since Matcher.toMatchResult()
returns a snapshot of the current group state.
For example you can write a lazy iterator to let you do
for (MatchResult match : allMatches(pattern, input)) {
// Use match, and maybe break without doing the work to find all possible matches.
}
by doing something like this:
public static Iterable<MatchResult> allMatches(
final Pattern p, final CharSequence input) {
return new Iterable<MatchResult>() {
public Iterator<MatchResult> iterator() {
return new Iterator<MatchResult>() {
// Use a matcher internally.
final Matcher matcher = p.matcher(input);
// Keep a match around that supports any interleaving of hasNext/next calls.
MatchResult pending;
public boolean hasNext() {
// Lazily fill pending, and avoid calling find() multiple times if the
// clients call hasNext() repeatedly before sampling via next().
if (pending == null && matcher.find()) {
pending = matcher.toMatchResult();
}
return pending != null;
}
public MatchResult next() {
// Fill pending if necessary (as when clients call next() without
// checking hasNext()), throw if not possible.
if (!hasNext()) { throw new NoSuchElementException(); }
// Consume pending so next call to hasNext() does a find().
MatchResult next = pending;
pending = null;
return next;
}
/** Required to satisfy the interface, but unsupported. */
public void remove() { throw new UnsupportedOperationException(); }
};
}
};
}
With this,
for (MatchResult match : allMatches(Pattern.compile("[abc]"), "abracadabra")) {
System.out.println(match.group() + " at " + match.start());
}
yields
a at 0 b at 1 a at 3 c at 4 a at 5 a at 7 b at 8 a at 10
I also had problems with transformations in IE9, I used -ms-transform: rotate(10deg)
and it didn't work. Tried everything I could, but the problem was in browser mode, to make transformations work, you need to set compatibility mode to "Standard IE9".
I don't know if this question is still relevant, but there is such possibility in Postman now. They added it a few months ago.
All you need is create simple .js file and run it via node.js. It looks like this:
var path = require('path'),
async = require('async'), //https://www.npmjs.com/package/async
newman = require('newman'),
parametersForTestRun = {
collection: path.join(__dirname, 'postman_collection.json'), // your collection
environment: path.join(__dirname, 'postman_environment.json'), //your env
};
parallelCollectionRun = function(done) {
newman.run(parametersForTestRun, done);
};
// Runs the Postman sample collection thrice, in parallel.
async.parallel([
parallelCollectionRun,
parallelCollectionRun,
parallelCollectionRun
],
function(err, results) {
err && console.error(err);
results.forEach(function(result) {
var failures = result.run.failures;
console.info(failures.length ? JSON.stringify(failures.failures, null, 2) :
`${result.collection.name} ran successfully.`);
});
});
Then just run this .js file ('node fileName.js' in cmd).

The code to compress/decompress a string
public static void CopyTo(Stream src, Stream dest) {
byte[] bytes = new byte[4096];
int cnt;
while ((cnt = src.Read(bytes, 0, bytes.Length)) != 0) {
dest.Write(bytes, 0, cnt);
}
}
public static byte[] Zip(string str) {
var bytes = Encoding.UTF8.GetBytes(str);
using (var msi = new MemoryStream(bytes))
using (var mso = new MemoryStream()) {
using (var gs = new GZipStream(mso, CompressionMode.Compress)) {
//msi.CopyTo(gs);
CopyTo(msi, gs);
}
return mso.ToArray();
}
}
public static string Unzip(byte[] bytes) {
using (var msi = new MemoryStream(bytes))
using (var mso = new MemoryStream()) {
using (var gs = new GZipStream(msi, CompressionMode.Decompress)) {
//gs.CopyTo(mso);
CopyTo(gs, mso);
}
return Encoding.UTF8.GetString(mso.ToArray());
}
}
static void Main(string[] args) {
byte[] r1 = Zip("StringStringStringStringStringStringStringStringStringStringStringStringStringString");
string r2 = Unzip(r1);
}
Remember that Zip
returns a byte[]
, while Unzip
returns a string
. If you want a string from Zip
you can Base64 encode it (for example by using Convert.ToBase64String(r1)
) (the result of Zip
is VERY binary! It isn't something you can print to the screen or write directly in an XML)
The version suggested is for .NET 2.0, for .NET 4.0 use the MemoryStream.CopyTo
.
IMPORTANT: The compressed contents cannot be written to the output stream until the GZipStream
knows that it has all of the input (i.e., to effectively compress it needs all of the data). You need to make sure that you Dispose()
of the GZipStream
before inspecting the output stream (e.g., mso.ToArray()
). This is done with the using() { }
block above. Note that the GZipStream
is the innermost block and the contents are accessed outside of it. The same goes for decompressing: Dispose()
of the GZipStream
before attempting to access the data.
I know this is a really old question, but in case someone is looking for the newer way to do this, use the spring util namespace:
<util:constant static-field="my.pkg.types.MyEnumType.TYPE1" />
As described in the spring documentation.
Suspend the process with CTRL+Z then use the command bg
to resume it in background. For example:
sleep 60
^Z #Suspend character shown after hitting CTRL+Z
[1]+ Stopped sleep 60 #Message showing stopped process info
bg #Resume current job (last job stopped)
More about job control and bg
usage in bash
manual page:
JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.
EDIT
To start a process where you can even kill the terminal and it still carries on running
nohup [command] [-args] > [filename] 2>&1 &
e.g.
nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &
To just ignore the output (not very wise) change the filename to /dev/null
To get the error message set to a different file change the &1
to a filename.
In addition: You can use the jobs
command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1
or kill %2
with the number being the index of the process.
Rather than relying on errors, you can query INFORMATION_SCHEMA.TABLES
to see if the table exists. If there's a record, it exists. If there's no record, it doesn't exist.
Or this:
$(document).ready(function(){
$(".header").click(function(){
$(this).children(".children").toggle();
});
$(".header a").click(function(e) {
return false;
});
});
Here's what i enjoyed the most so far regarding private/public methods/members and instantiation in javascript:
here is the article: http://www.sefol.com/?p=1090
and here is the example:
var Person = (function () {
//Immediately returns an anonymous function which builds our modules
return function (name, location) {
alert("createPerson called with " + name);
var localPrivateVar = name;
var localPublicVar = "A public variable";
var localPublicFunction = function () {
alert("PUBLIC Func called, private var is :" + localPrivateVar)
};
var localPrivateFunction = function () {
alert("PRIVATE Func called ")
};
var setName = function (name) {
localPrivateVar = name;
}
return {
publicVar: localPublicVar,
location: location,
publicFunction: localPublicFunction,
setName: setName
}
}
})();
//Request a Person instance - should print "createPerson called with ben"
var x = Person("ben", "germany");
//Request a Person instance - should print "createPerson called with candide"
var y = Person("candide", "belgium");
//Prints "ben"
x.publicFunction();
//Prints "candide"
y.publicFunction();
//Now call a public function which sets the value of a private variable in the x instance
x.setName("Ben 2");
//Shouldn't have changed this : prints "candide"
y.publicFunction();
//Should have changed this : prints "Ben 2"
x.publicFunction();
Quite a few of these solutions suggest referencing the public_path() of the Laravel application in order to locate the file. Sometimes you'll want to control access to the file or offer real-time monitoring of the file. In this case, you'll want to keep the directory private and limit access by a method in a controller class. The following method should help with this:
public function show(Request $request, File $file) {
// Perform validation/authentication/auditing logic on the request
// Fire off any events or notifiations (if applicable)
return response()->download(storage_path('app/' . $file->location));
}
There are other paths that you could use as well, described on Laravel's helper functions documentation
As far as I understand, you create a Movie class:
class Movie
{
private:
std::string _title;
std::string _director;
int _year;
int _rating;
std::vector<std::string> actors;
};
and having such class, you create a vector instance:
std::vector<Movie*> movies;
so, you can add any movie to your movies collection. Since you are creating a vector of pointers to movies, do not forget to free the resources allocated by your movie instances OR you could use some smart pointer to deallocate the movies automatically:
std::vector<shared_ptr<Movie>> movies;
You have to add another list:
list[:0]=['foo']
Improving the @Derek Springer
post with fill length function:
public static String getFileWithDate(String fileName, String fileSaperator, String dateFormat) {
String FileNamePrefix = fileName.substring(0, fileName.lastIndexOf(fileSaperator));
String FileNameSuffix = fileName.substring(fileName.lastIndexOf(fileSaperator)+1, fileName.length());
//System.out.println("File= Prefix~Suffix:"+FileNamePrefix +"~"+FileNameSuffix);
String newFileName = new SimpleDateFormat("'"+FileNamePrefix+"_'"+dateFormat+"'"+fileSaperator+FileNameSuffix+"'").format(new Date());
System.out.println("New File:"+newFileName);
return newFileName;
}
Using the funciton and its Output:
String fileSaperator = ".", format = "yyyyMMMdd_HHmm";
getFileWithDate("Text1.txt", fileSaperator, format);
getFileWithDate("Text1.doc", fileSaperator, format);
getFileWithDate("Text1.txt.json", fileSaperator, format);
Output:
Old File:Text1.txt New File:Text1_2020Nov11_1807.txt
Old File:Text1.doc New File:Text1_2020Nov11_1807.doc
Old File:Text1.txt.json New File:Text1.txt_2020Nov11_1807.json
You can try with this code (Same case)
chaine1 + chaine2;
I suggest you also (I prefer this) the string.concat method
The a == b
expression invokes A.__eq__
, since it exists. Its code includes self.value == other
. Since int's don't know how to compare themselves to B's, Python tries invoking B.__eq__
to see if it knows how to compare itself to an int.
If you amend your code to show what values are being compared:
class A(object):
def __eq__(self, other):
print("A __eq__ called: %r == %r ?" % (self, other))
return self.value == other
class B(object):
def __eq__(self, other):
print("B __eq__ called: %r == %r ?" % (self, other))
return self.value == other
a = A()
a.value = 3
b = B()
b.value = 4
a == b
it will print:
A __eq__ called: <__main__.A object at 0x013BA070> == <__main__.B object at 0x013BA090> ?
B __eq__ called: <__main__.B object at 0x013BA090> == 3 ?
OK, Firefox 7 implemented text-overflow: ellipsis
as well as text-overflow: "string"
. Final release is planned for 2011-09-27.
I used fake UserAgent.
How to use:
from fake_useragent import UserAgent
import requests
ua = UserAgent()
print(ua.chrome)
header = {'User-Agent':str(ua.chrome)}
print(header)
url = "https://www.hybrid-analysis.com/recent-submissions?filter=file&sort=^timestamp"
htmlContent = requests.get(url, headers=header)
print(htmlContent)
Output:

You can also use REPLACE()
:
UPDATE Table
SET Column = REPLACE(Column, 'Test123', 'Test')
Add System.Configuration
as a reference then:
using System.Configuration;
...
string conn =
ConfigurationManager.ConnectionStrings["ConnectionName"].ConnectionString;
We request that the developer asking for the pull request state that they would like the branch deleted. Most of the time this is the case. There are times when a branch is needed (e.g. copying the changes to another release branch).
My fingers have memorized our process:
git checkout <feature-branch>
git pull
git checkout <release-branch>
git pull
git merge --no-ff <feature-branch>
git push
git tag -a branch-<feature-branch> -m "Merge <feature-branch> into <release-branch>"
git push --tags
git branch -d <feature-branch>
git push origin :<feature-branch>
A branch is for work. A tag marks a place in time. By tagging each branch merge we can resurrect a branch if that is needed. The branch tags have been used several times to review changes.
the documentations refers to an ASP.NET application.
You can try and have a look at my answer here.
I have an example attached to my reply.
Another example for ASP.NET MVC3 can be found here.
Try this:
git reset --hard HEAD
git pull
It should do what you want.
Here's a plugin which can list all event handlers for any given element/event:
$.fn.listHandlers = function(events, outputFunction) {
return this.each(function(i){
var elem = this,
dEvents = $(this).data('events');
if (!dEvents) {return;}
$.each(dEvents, function(name, handler){
if((new RegExp('^(' + (events === '*' ? '.+' : events.replace(',','|').replace(/^on/i,'')) + ')$' ,'i')).test(name)) {
$.each(handler, function(i,handler){
outputFunction(elem, '\n' + i + ': [' + name + '] : ' + handler );
});
}
});
});
};
Use it like this:
// List all onclick handlers of all anchor elements:
$('a').listHandlers('onclick', console.info);
// List all handlers for all events of all elements:
$('*').listHandlers('*', console.info);
// Write a custom output function:
$('#whatever').listHandlers('click',function(element,data){
$('body').prepend('<br />' + element.nodeName + ': <br /><pre>' + data + '<\/pre>');
});

Modules Preconditions:
The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (
precondition="managedHandler"
) only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />
If you remove the attribute
precondition="managedHandler"
, Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "
managedHandler
" precondition.To enable all managed modules to run for all requests without configuring each module entry to remove the "
managedHandler
" precondition, use therunAllManagedModulesForAllRequests
property in the<modules>
section:<modules runAllManagedModulesForAllRequests="true" />
When you use this property, the "
managedHandler
" precondition has no effect and all managed modules run for all requests.
Copied from IIS Modules Overview: Preconditions
One simple way to get all the queries you need is to use the data from information_schema and concat.
SELECT concat('CREATE TABLE new_db.', TABLE_NAME, ' LIKE old_db.', TABLE_NAME, ';') FROM `TABLES` WHERE TABLE_SCHEMA = 'old_db';
You'll then get a list of results that looks like this:
CREATE TABLE new_db.articles LIKE old_db.articles;
CREATE TABLE new_db.categories LIKE old_db.categories;
CREATE TABLE new_db.users LIKE old_db.users;
...
You can then just run those queries.
However it won't work with MySQL Views. You can avoid them by appending AND TABLE_TYPE = 'BASE TABLE'
from the initial query:
This is one of the proposed solutions found in the article Jacob mentioned, and it worked great as a manual way to change the password without having to use the email reset.
wp_users
, add a key, like abc123 to the
user_activation
column. refer to http://www.w3schools.com/php/php_mysql_select.asp . If you are a beginner and want to learn, w3schools is a good place.
<?php
$con=mysqli_connect("localhost","root","YOUR_PHPMYADMIN_PASSWORD","hrmwaitrose");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM employee");
while($row = mysqli_fetch_array($result))
{
echo $row['FirstName'] . " " . $row['LastName']; //these are the fields that you have stored in your database table employee
echo "<br />";
}
mysqli_close($con);
?>
You can similarly echo
it inside your table
<?php
echo "<table>";
while($row = mysqli_fetch_array($result))
{
echo "<tr><td>" . $row['FirstName'] . "</td><td> " . $row['LastName'] . "</td></tr>"; //these are the fields that you have stored in your database table employee
}
echo "</table>";
mysqli_close($con);
?>
x or "default"
works best — i can even use a function call inline, without executing it twice or using extra variable:
self.lineEdit_path.setText( self.getDir(basepath) or basepath )
I use it when opening Qt's dialog.getExistingDirectory()
and canceling, which returns empty string.
If you want to set the Cache-Control header, there's nothing in the IIS7 UI to do this, sadly.
You can however drop this web.config in the root of the folder or site where you want to set it:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<staticContent>
<clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="7.00:00:00" />
</staticContent>
</system.webServer>
</configuration>
That will inform the client to cache content for 7 days in that folder and all subfolders.
You can also do this by editing the IIS7 metabase via appcmd.exe
, like so:
\Windows\system32\inetsrv\appcmd.exe set config "Default Web Site/folder" -section:system.webServer/staticContent -clientCache.cacheControlMode:UseMaxAge \Windows\system32\inetsrv\appcmd.exe set config "Default Web Site/folder" -section:system.webServer/staticContent -clientCache.cacheControlMaxAge:"7.00:00:00"
It means to interpret the string literally (that is, you cannot escape any characters within the string if you use the @ prefix). It enhances readability in cases where it can be used.
For example, if you were working with a UNC path, this:
@"\\servername\share\folder"
is nicer than this:
"\\\\servername\\share\\folder"
PowerShell 3 has the $PSScriptRoot
automatic variable:
Contains the directory from which a script is being run.
In Windows PowerShell 2.0, this variable is valid only in script modules (.psm1). Beginning in Windows PowerShell 3.0, it is valid in all scripts.
Don't be fooled by the poor wording. PSScriptRoot
is the directory of the current file.
In PowerShell 2, you can calculate the value of $PSScriptRoot
yourself:
# PowerShell v2
$PSScriptRoot = Split-Path -Parent -Path $MyInvocation.MyCommand.Definition
with open(fpath, 'rb') as myfile:
fstr = myfile.read()
I encounter this error because the file is empty. This answer may not a correct answer for this question but should give developers a hint like me.
There are a couple of answers posted here that will give you the text effects you want, but...
The thing about tables is that they are organized collections of labels and data. Having both a label ("Datum") and the value that it labels in the same cell is oh so very wrong. The label should be in a <th>
element, with the value in a <td>
either in the same row or the same column (depending on the data arrangement you are trying to achieve). You can have <th>
elements running either vertically or horizontally or both, but if you don't have heading cells (which is what <th>
means), you don't have a table, you just have a meaningless grid of text. It would be preferable, too, to have a <caption>
element to label the table as a whole (you don't have to display the caption, but it should be there for accessibility) and have a summary="blah blah blah"
attribute in the table tag, again for accessibility. So your HTML should probably look a lot more like this:
<html>
<head>
<title>Test page with Table<title>
<style type="text/css">
th {
font-size: 35px;
font-weight: bold;
padding-left: 5px;
padding-bottom: 3px;
}
</style>
</head>
<body>
<table id="table_1" summary="This table has both labels and values">
<caption>Table of Stuff</caption>
<tr>
<th>Datum</th>
<td>November 2010</td>
</tr>
</table>
</body>
</html>
That may not be exactly what you want -- it's hard to tell whether November 2010 is a data point or a label from what you've posted, and "Datum" isn't a helpful label in any case. Play with it a bit, but make sure that when your table is finished it actually has some kind of semantic meaning. If it's not a real table of data, then don't use a <table>
to lay it out.
Great solution, thank you! I took the AndyDBell's question and Cuong Le's answer to build an example with two diferent interface's implementation:
public interface ISample
{
int SampleId { get; set; }
}
public class Sample1 : ISample
{
public int SampleId { get; set; }
public Sample1() { }
}
public class Sample2 : ISample
{
public int SampleId { get; set; }
public String SampleName { get; set; }
public Sample2() { }
}
public class SampleGroup
{
public int GroupId { get; set; }
public IEnumerable<ISample> Samples { get; set; }
}
class Program
{
static void Main(string[] args)
{
//Sample1 instance
var sz = "{\"GroupId\":1,\"Samples\":[{\"SampleId\":1},{\"SampleId\":2}]}";
var j = JsonConvert.DeserializeObject<SampleGroup>(sz, new SampleConverter<Sample1>());
foreach (var item in j.Samples)
{
Console.WriteLine("id:{0}", item.SampleId);
}
//Sample2 instance
var sz2 = "{\"GroupId\":1,\"Samples\":[{\"SampleId\":1, \"SampleName\":\"Test1\"},{\"SampleId\":2, \"SampleName\":\"Test2\"}]}";
var j2 = JsonConvert.DeserializeObject<SampleGroup>(sz2, new SampleConverter<Sample2>());
//Print to show that the unboxing to Sample2 preserved the SampleName's values
foreach (var item in j2.Samples)
{
Console.WriteLine("id:{0} name:{1}", item.SampleId, (item as Sample2).SampleName);
}
Console.ReadKey();
}
}
And a generic version to the SampleConverter:
public class SampleConverter<T> : CustomCreationConverter<ISample> where T: new ()
{
public override ISample Create(Type objectType)
{
return ((ISample)new T());
}
}

I had exactly the same problem right after switching off some (in my opinion unneccessary) Windows services. It turned out that when I switched ON again the "Application Experience"
everything resumed working fine.
May be you simply have to turn on this service? To switch ON Application Experience:
Click the Windows start buttonn.
In the box labeled "Search programs and files" type services.msc
and click the search button. A new window with title "Services" opens.
Right click on "Application Experience" line and select "Properties" from popup menu.
Change Startup type to "Automatic (delayed start)".
Restart computer.
Application Experiences should prevent the problem in the future.
For me, I had to remove
<item name="android:gravity">center_vertical</item>
from RelativeLayout, so children's configuration would work:
<item name="android:layout_centerVertical">true</item>
create table scores (
user_id int,
score int
)
select t.range as [score range], count(*) as [number of occurences]
from (
select user_id,
case when score >= 0 and score < 10 then '0-9'
case when score >= 10 and score < 20 then '10-19'
...
else '90-99' as range
from scores) t
group by t.range
When you have Overridden Methods with same Name Use the helper below
public static TValue GetControllerMethodAttributeValue<T, TT, TAttribute, TValue>(this T type, Expression<Func<T, TT>> exp, Func<TAttribute, TValue> valueSelector) where TAttribute : Attribute
{
var memberExpression = exp?.Body as MethodCallExpression;
if (memberExpression.Method.GetCustomAttributes(typeof(TAttribute), false).FirstOrDefault() is TAttribute attr && valueSelector != null)
{
return valueSelector(attr);
}
return default(TValue);
}
Usage: var someController = new SomeController(Some params); var str = typeof(SomeController).GetControllerMethodAttributeValue(x => someController.SomeMethod(It.IsAny()), (RouteAttribute routeAttribute) => routeAttribute.Template);
You can't "directly" mock static method (hence extension method) with mocking framework. You can try Moles (http://research.microsoft.com/en-us/projects/pex/downloads.aspx), a free tool from Microsoft that implements a different approach. Here is the description of the tool:
Moles is a lightweight framework for test stubs and detours in .NET that is based on delegates.
Moles may be used to detour any .NET method, including non-virtual/static methods in sealed types.
You can use Moles with any testing framework (it's independent about that).
It's database specific. You haven't specified what database engine you are using.
e.g. in PostgreSQL you do cast(myvalue as date).
If you're in the middle of a commit (i.e. in your editor already), you can cancel it by deleting all lines above the first #
. That will abort the commit.
So you can delete all lines so that the commit message is empty, then save the file:
You'll then get a message that says Aborting commit due to empty commit message.
.
EDIT:
You can also delete all the lines and the result will be exactly the same.
To delete all lines in vim (if that is your default editor), once you're in the editor, type gg
to go to the first line, then dG
to delete all lines. Finally, write and quit the file with wq
and your commit will be aborted.
This answer is similar to Alexander Ukhov's answer, except that it uses touch events rather than click events. Those event allow the parent to display the proper pressed states (e.g., ripple effect). This answer is also in Kotlin instead of Java.
view.setOnTouchListener { view, motionEvent ->
(view.parent as View).onTouchEvent(motionEvent)
}
So, the idea of mocking the class under test is anathima to testing practice. You should NOT do this. Because you have done so, your test is entering Mockito's mocking classes not your class under test.
Spying will also not work because this only provides a wrapper / proxy around the spied class. Once execution is inside the class it will not go through the proxy and therefore not hit the spy. UPDATE: although I believe this to be true of Spring proxies it appears to not be true of Mockito spies. I set up a scenario where method m1()
calls m2()
. I spy the object and stub m2()
to doNothing
. When I invoke m1()
in my test, m2()
of the class is not reached. Mockito invokes the stub. So using a spy to accomplish what is being asked is possible. However, I would reiterate that I would consider it bad practice (IMHO).
You should mock all the classes on which the class under test depends. This will allow you to control the behavior of the methods invoked by the method under test in that you control the class that those methods invoke.
If your class creates instances of other classes, consider using factories.

When you want to pass new information to your application, you need to use POST form. In Razor you can use the following
View Code:
@* By default BeginForm use FormMethod.Post *@
@using(Html.BeginForm("Update")){
@Html.Hidden("id", Model.Id)
@Html.Hidden("productid", Model.ProductId)
@Html.TextBox("qty", Model.Quantity)
@Html.TextBox("unitrate", Model.UnitRate)
<input type="submit" value="Update" />
}
Controller's actions
[HttpGet]
public ActionResult Update(){
//[...] retrive your record object
return View(objRecord);
}
[HttpPost]
public ActionResult Update(string id, string productid, int qty, decimal unitrate)
{
if (ModelState.IsValid){
int _records = UpdatePrice(id,productid,qty,unitrate);
if (_records > 0){ {
return RedirectToAction("Index1", "Shopping");
}else{
ModelState.AddModelError("","Can Not Update");
}
}
return View("Index1");
}
Note that alternatively, if you want to use @Html.TextBoxFor(model => model.Quantity)
you can either have an input with the name (respectecting case) "Quantity"
or you can change your POST Update() to receive an object parameter, that would be the same type as your strictly typed view. Here's an example:
Model
public class Record {
public string Id { get; set; }
public string ProductId { get; set; }
public string Quantity { get; set; }
public decimal UnitRate { get; set; }
}
View
@using(Html.BeginForm("Update")){
@Html.HiddenFor(model => model.Id)
@Html.HiddenFor(model => model.ProductId)
@Html.TextBoxFor(model=> model.Quantity)
@Html.TextBoxFor(model => model.UnitRate)
<input type="submit" value="Update" />
}
Post Action
[HttpPost]
public ActionResult Update(Record rec){ //Alternatively you can also use FormCollection object as well
if(TryValidateModel(rec)){
//update code
}
return View("Index1");
}
This might not be very applicable to others, but my problem was that the changes I made was NOT saved yet! Press CMD + S

There is a check placed at Yarn level for Virtual and Physical memory usage ratio. Issue is not only that VM doesn't have sufficient physical memory. But it is because Virtual memory usage is more than expected for given physical memory.
Note : This is happening on Centos/RHEL 6 due to its aggressive allocation of virtual memory.
It can be resolved either by :
Disable virtual memory usage check by setting yarn.nodemanager.vmem-check-enabled to false;
Increase VM:PM ratio by setting yarn.nodemanager.vmem-pmem-ratio to some higher value.
