Turns out that the Eval.svc.cs needed its namespace changed to EvalServiceLibary, rather than EvalServiceSite.
I had this problem because I was calling a method
await myClass.myStaticMethod(myString);
but I was setting myString with
var myString = String.Format({some dynamic-type values})
which resulted in a dynamic
type, not a string
, thus when I tried to await on myClass.myStaticMethod(myString)
, the compiler thought I meant to call myClass.myStaticMethod(dynamic myString)
. This compiled fine because, again, in a dynamic context, it's all good until it blows up at run-time, which is what happened because there is no implementation of the dynamic version of myStaticMethod
, and this error message didn't help whatsoever, and the fact that Intellisense would take me to the correct definition didn't help either.
Tricky!
However, by forcing the result type to string, like:
var myString = String.Format({some dynamic-type values})
to
string myString = String.Format({some dynamic-type values})
my call to myStaticMethod
routed properly
Unfortunately the link in the exception text, http://go.microsoft.com/fwlink/?LinkId=70353, is broken. However, it used to lead to http://msdn.microsoft.com/en-us/library/ms733768.aspx which explains how to set the permissions.
It basically informs you to use the following command:
netsh http add urlacl url=http://+:80/MyUri user=DOMAIN\user
You can get more help on the details using the help of netsh
For example: netsh http add ?
Gives help on the http add
command.
You are missing an equality:
var query = (from p in tblPersoon where p.id == 5 select p).Single();
where
clause must result in a boolean.
OR you should not be using where
at all:
var query = (from p in tblPersoon select p).Single();
DataMember attribute is not mandatory to add to serialize data. When DataMember attribute is not added, old XMLSerializer serializes the data. Adding a DataMember provides useful properties like order, name, isrequired which cannot be used otherwise.
When you are using GET Method the contract must be this.
[WebGet(UriTemplate = "/", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
List<User> Get();
with this we have a json without the boot parameter

From my recent experience i would recommend ksoap library to consume a Soap WCF Service, its actually really easy, this anddev thread migh help you out too.
I've been having this same problem for over a day now - finally figured it out. Thanks to @Sameh for the hint.
Your service is probably working just fine. Testing POST messages using the address bar of a browser won't work. You need to use Fiddler to test a POST message.

literal_eval
, a somewhat safer version of eval
(will only evaluate literals ie strings, lists etc):
from ast import literal_eval
python_dict = literal_eval("{'a': 1}")
json.loads
but it would require your string to use double quotes:
import json
python_dict = json.loads('{"a": 1}')
Probably the password of the account that you trying to send e-mail is expired. Just check your password policy expire date.
My cause was different I referenced a web service then I got this message.
Then I changed my target .Net Framework 4.0 to .Net Framework 2.0 and re-refer my webservice. After a few changes problem solved. There is no error worked fine.
hope this helps!
Using Gson
List<Student> students = new ArrayList<>();
JSONArray jsonArray = new JSONArray(stringJsonContainArray);
for (int i = 0; i < jsonArray.length(); i++) {

In kotlin you can use like this
fun changeDateFormats(currentFormat: String, dateString: String): String {
var result = ""
try {
val formatterOld = SimpleDateFormat(currentFormat, Locale.getDefault())
formatterOld.timeZone = TimeZone.getTimeZone("UTC")
var date: Date? = null
date = formatterOld.parse(dateString)
val dayFormate = SimpleDateFormat("d", Locale.getDefault())
var day = dayFormate.format(date)
val formatterNew = SimpleDateFormat("hh:mm a, d'" + getDayOfMonthSuffix(day.toInt()) + "' MMM yy", Locale.getDefault())
if (date != null) {
result = formatterNew.format(date)
}
} catch (e: ParseException) {
e.printStackTrace()
return dateString
}
return result
}
private fun getDayOfMonthSuffix(n: Int): String {
if (n in 11..13) {
return "th"
}
when (n % 10) {
1 -> return "st"
2 -> return "nd"
3 -> return "rd"
else -> return "th"
}
}
set like this
txt_chat_time_me.text = changeDateFormats("SERVER_DATE", "DATE")
Andrew had a great response but I wanted to tweek it a little. The way this is different is that I like my ModelViews to not have overhead data in them. Just the data for the object. It seem that ViewData fits the bill for over head data, but of course I'm new at this. I suggest doing something like this.
Controller
virtual public ActionResult DisplaySomeWidget(int id)
{
SomeModelView returnData = someDataMapper.getbyid(1);
var serializer = new JavaScriptSerializer();
ViewData["JSON"] = serializer.Serialize(returnData);
return View(myview, returnData);
}
View
//create base js object;
var myWidget= new Widget(); //Widget is a class with a public member variable called data.
myWidget.data= <%= ViewData["JSON"] %>;
What This does for you is it gives you the same data in your JSON as in your ModelView so you can potentially return the JSON back to your controller and it would have all the parts. This is similar to just requesting it via a JSONRequest however it requires one less call so it saves you that overhead. BTW this is funky for Dates but that seems like another thread.

For all the issue related to KeyBoard just use IQKeyBoardManager it's helpful. https://github.com/hackiftekhar/IQKeyboardManager.

It's been pointed out that the last d
digits of a perfect square can only take on certain values. The last d
digits (in base b
) of a number n
is the same as the remainder when n
is divided by b
d
, ie. in C notation n % pow(b, d)
.
This can be generalized to any modulus m
, ie. n % m
can be used to rule out some percentage of numbers from being perfect squares. The modulus you are currently using is 64, which allows 12, ie. 19% of remainders, as possible squares. With a little coding I found the modulus 110880, which allows only 2016, ie. 1.8% of remainders as possible squares. So depending on the cost of a modulus operation (ie. division) and a table lookup versus a square root on your machine, using this modulus might be faster.
By the way if Java has a way to store a packed array of bits for the lookup table, don't use it. 110880 32-bit words is not much RAM these days and fetching a machine word is going to be faster than fetching a single bit.
I would recommend reading in the line into a string, then splitting it based on the spaces. For this, you can use the getline(...) function. The trick is having a dynamic sized data structure to hold the strings once it's split. Probably the easiest to use would be a vector.
#include <string>
#include <vector>
...
string rawInput;
vector<String> numbers;
while( getline( cin, rawInput, ' ' ) )
{
numbers.push_back(rawInput);
}
So say the input looks like this:
Enter a number, or numbers separated by a space, between 1 and 1000.
10 5 20 1 200 7
You will now have a vector, numbers, that contains the elements: {"10","5","20","1","200","7"}.
Note that these are still strings, so not useful in arithmetic. To convert them to integers, we use a combination of the STL function, atoi(...), and because atoi requires a c-string instead of a c++ style string, we use the string class' c_str() member function.
while(!numbers.empty())
{
string temp = numbers.pop_back();//removes the last element from the string
num = atoi( temp.c_str() ); //re-used your 'num' variable from your code
...//do stuff
}
Now there's some problems with this code. Yes, it runs, but it is kind of clunky, and it puts the numbers out in reverse order. Lets re-write it so that it is a little more compact:
#include <string>
...
string rawInput;
cout << "Enter a number, or numbers separated by a space, between 1 and 1000." << endl;
while( getline( cin, rawInput, ' ') )
{
num = atoi( rawInput.c_str() );
...//do your stuff
}
There's still lots of room for improvement with error handling (right now if you enter a non-number the program will crash), and there's infinitely more ways to actually handle the input to get it in a usable number form (the joys of programming!), but that should give you a comprehensive start. :)
Note: I had the reference pages as links, but I cannot post more than two since I have less than 15 posts :/
Edit: I was a little bit wrong about the atoi behavior; I confused it with Java's string->Integer conversions which throw a Not-A-Number exception when given a string that isn't a number, and then crashes the program if the exception isn't handled. atoi(), on the other hand, returns 0, which is not as helpful because what if 0 is the number they entered? Let's make use of the isdigit(...) function. An important thing to note here is that c++ style strings can be accessed like an array, meaning rawInput[0] is the first character in the string all the way up to rawInput[length - 1].
#include <string>
#include <ctype.h>
...
string rawInput;
cout << "Enter a number, or numbers separated by a space, between 1 and 1000." << endl;
while( getline( cin, rawInput, ' ') )
{
bool isNum = true;
for(int i = 0; i < rawInput.length() && isNum; ++i)
{
isNum = isdigit( rawInput[i]);
}
if(isNum)
{
num = atoi( rawInput.c_str() );
...//do your stuff
}
else
cout << rawInput << " is not a number!" << endl;
}
The boolean (true/false or 1/0 respectively) is used as a flag for the for-loop, which steps through each character in the string and checks to see if it is a 0-9 digit. If any character in the string is not a digit, the loop will break during it's next execution when it gets to the condition "&& isNum" (assuming you've covered loops already). Then after the loop, isNum is used to determine whether to do your stuff, or to print the error message.
^ is binary (as in base-2) xor, not exponentiation (which is not available as a Java operator). For exponentiation, see java.lang.Math.pow().
To upgrade pip for Python3.4+, you must use pip3 as follows:
sudo pip3 install pip --upgrade
This will upgrade pip located at: /usr/local/lib/python3.X/dist-packages
Otherwise, to upgrade pip for Python2.7, you would use pip as follows:
sudo pip install pip --upgrade
This will upgrade pip located at: /usr/local/lib/python2.7/dist-packages
What you could do is use ng-repeat
passing in the value of whatever you're iterating on to the ng-checked
and from there utilising ng-class
to apply your styles depending on the result.
I did something similar recently and it worked for me.
Using JQuery would be good;
<a href="#" id="youLink">Call JavaScript </a>
$("#yourLink").click(function(e){
//do what ever you want...
});
You could always use ADO to write the results out to the worksheet cells from a recordset object
select * from your_table where MONTH(mont_year) = MONTH(NOW()) and YEAR(mont_year) = YEAR(NOW());
Note: (month_year) means your column that contain date format. I think that will solve your problem. Let me know if that query doesn't works.
Your visual basic code would look something like this:
Dim cmd as New SqlCommand("SELECT * FROM compliance_corner WHERE (body LIKE '%' + @query + '%') OR (title LIKE '%' + @query + '%')")
cmd.Parameters.Add("@query", searchString)
Felipsmartins is correct.
It is worth mentioning that it is because you cannot really use the -d/--data option if this is not a POST request. But this is still possible if you use the -G option.
Which means you can do this:
curl -X DELETE -G 'http://localhost:5000/locations' -d 'id=3'
Here it is a bit silly but when you are on the command line and you have a lot of parameters, it is a lot tidier.
I am saying this because cURL commands are usually quite long, so it is worth making it on more than one line escaping the line breaks.
curl -X DELETE -G \
'http://localhost:5000/locations' \
-d id=3 \
-d name=Mario \
-d surname=Bros
This is obviously a lot more comfortable if you use zsh. I mean when you need to re-edit the previous command because zsh lets you go line by line. (just saying)
Hope it helps.
You can either do this, normal JavaScript:
className={'wrapper searchDiv ' + this.state.something}
or the string template version, with backticks:
className={`wrapper searchDiv ${this.state.something}`}
Both types are of course just JavaScript, but the first pattern is the traditional kind.
Anyway, in JSX, anything enclosed in curly brackets is executed as JavaScript, so you can basically do whatever you want there. But combining JSX strings and curly brackets is a no-go for attributes.
For primitive types (e.g. numbers, booleans, strings, etc.), there is no difference between toBe
and toEqual
; either one will work for 5
, true
, or "the cake is a lie"
.
To understand the difference between toBe
and toEqual
, let's imagine three objects.
var a = { bar: 'baz' },
b = { foo: a },
c = { foo: a };
Using a strict comparison (===
), some things are "the same":
> b.foo.bar === c.foo.bar
true
> b.foo.bar === a.bar
true
> c.foo === b.foo
true
But some things, even though they are "equal", are not "the same", since they represent objects that live in different locations in memory.
> b === c
false
Jasmine's toBe
matcher is nothing more than a wrapper for a strict equality comparison
expect(c.foo).toBe(b.foo)
is the same thing as
expect(c.foo === b.foo).toBe(true)
Don't just take my word for it; see the source code for toBe.
But b
and c
represent functionally equivalent objects; they both look like
{ foo: { bar: 'baz' } }
Wouldn't it be great if we could say that b
and c
are "equal" even if they don't represent the same object?
Enter toEqual
, which checks "deep equality" (i.e. does a recursive search through the objects to determine whether the values for their keys are equivalent). Both of the following tests will pass:
expect(b).not.toBe(c);
expect(b).toEqual(c);
Hope that helps clarify some things.
In Java create the pattern with Pattern p = Pattern.compile("^\\w{14}$");

Usually there is an information about the problem in localhost.[date].log. But sometimes there is nothing in this log. This can happen if there is messed configuration of the project (several developers worked on it for a long time and each added something from himself). I faced this problem WITHOUT any information in log. Rather fast and robust approach:
Try to remove everything which can cause any problem from web.xml. You even can remove everything except tag. If application still cannot be deployed - go on.
Remove every *.xml descriptor from WEB-INF/classes. If application cannot be deployed - go on.
Remove all logging configuration you can find in your war (logging.properties, log4j.properties). Try to deploy. At this step I've got more informative error, but deployment still failed.
After googling for this error I found out that project included old version of xerces, which clashed with Tomcat's version (which was newer) and didn't the application to be deployed. After upgrade of xerces in web-application everything became fine.
If you want to have the ListView in an AppCompatActivity instead of ListActivity, you can do the following (Modifying @Shardul's answer):
public class ListViewDemoActivity extends AppCompatActivity {
//LIST OF ARRAY STRINGS WHICH WILL SERVE AS LIST ITEMS
ArrayList<String> listItems=new ArrayList<String>();
//DEFINING A STRING ADAPTER WHICH WILL HANDLE THE DATA OF THE LISTVIEW
ArrayAdapter<String> adapter;
//RECORDING HOW MANY TIMES THE BUTTON HAS BEEN CLICKED
int clickCounter=0;
private ListView mListView;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.activity_list_view_demo);
if (mListView == null) {
mListView = (ListView) findViewById(R.id.listDemo);
}
adapter=new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
listItems);
setListAdapter(adapter);
}
//METHOD WHICH WILL HANDLE DYNAMIC INSERTION
public void addItems(View v) {
listItems.add("Clicked : "+clickCounter++);
adapter.notifyDataSetChanged();
}
protected ListView getListView() {
if (mListView == null) {
mListView = (ListView) findViewById(R.id.listDemo);
}
return mListView;
}
protected void setListAdapter(ListAdapter adapter) {
getListView().setAdapter(adapter);
}
protected ListAdapter getListAdapter() {
ListAdapter adapter = getListView().getAdapter();
if (adapter instanceof HeaderViewListAdapter) {
return ((HeaderViewListAdapter)adapter).getWrappedAdapter();
} else {
return adapter;
}
}
}
And in you layout instead of using android:id="@android:id/list"
you can use android:id="@+id/listDemo"
So now you can have a ListView
inside a normal AppCompatActivity
.
I had the same issue trying to find text in files with powershell. I used the following - to stay as close to the Linux environment as possible.
Hopefully this helps somebody:
PowerShell:
PS) new-alias grep findstr
PS) ls -r *.txt | cat | grep "some random string"
Explanation:
ls - lists all files
-r - recursively (in all files and folders and subfolders)
*.txt - only .txt files
| - pipe the (ls) results to next command (cat)
cat - show contents of files comming from (ls)
| - pipe the (cat) results to next command (grep)
grep - search contents from (cat) for "some random string" (alias to findstr)
Yes, this works as well:
PS) ls -r *.txt | cat | findstr "some random string"
For Bootstrap 3
here's how to do it.
Add a modal-wide
style to your HTML markup (as adapted from the example in the Bootstrap 3 docs)
<div class="modal fade modal-wide" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 id="myModalLabel" class="modal-title">Modal title</h4>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
</div><!-- /.modal -->
and add the following CSS
.modal-wide .modal-dialog {
width: 80%; /* or whatever you wish */
}
There is no need to override margin-left
in Bootstrap 3
to get this to be centered now.
To enable/disable draggable in jQuery I used:
$("#draggable").draggable({ disabled: true });
$("#draggable").draggable({ disabled: false });
@Calciphus answer didn't work for me with the opacity problem, so I used:
div.ui-state-disabled.ui-draggable-disabled {opacity: 1;}
Worked on mobile devices either.
Here is the code: http://jsfiddle.net/nn5aL/1/

Do not use [^\w\s]
, this will remove letters with accents (like àèéìòù), not to mention to Cyrillic or Chinese, letters coming from such languages will be completed removed.
You really don't want remove these letters together with all the special characters. You have two chances:

Try this little crumpet:

value = [NSNumber numberWithFloat:self.sensativity];
[[NSUserDefaults standardUserDefaults] setObject:value forKey:@"sensativity"];
}
-(void)loadUserSettings{

if(value == nil){
self.sensativity = 4.0;
}else{

Treat everything as an object. Seems to work for me.
Following snippet will do the desired function:
Type t = obj.GetType(); // Where obj is object whose properties you need.
PropertyInfo [] pi = t.GetProperties();
foreach (PropertyInfo p in pi)
{
System.Console.WriteLine(p.Name + " : " + p.GetValue(obj));
}
I think if you write this as extension method you could use it on all type of objects.
Try using:
selenium.select("id=items","label=engineering")
or
selenium.select("id=items","index=3")

Because "abstract" means: "Implements no functionality", and "static" means: "There is functionality even if you don't have an object instance". And that's a logical contradiction.
This is to add to of Gilles' Answer. There are many ways to get this done but personally I prefer something lightweight, easy to remember and universally available (e.g. come with standard LTS installations of your preferred Linux flavor or easy to install) on common *nix systems.
Here are the options in their preferred order:
Python Json.tool module
echo '{"foo": "lorem", "bar": "ipsum"}' | python -mjson.tool
pros: almost available everywhere; cons: no color coding
jq (may require one time installation)
echo '{"foo": "lorem", "bar": "ipsum"}' | jq
cons: needs to install jq; pros: color coding and versatile
json_pp (available in Ubuntu 16.04 LTS)
echo '{"foo": "lorem", "bar": "ipsum"}' | json_pp
For Ruby users
gem install jsonpretty
echo '{"foo": "lorem", "bar": "ipsum"}' | jsonpretty
Although systemd indeed does not provide way to pass command-line arguments for unit files, there are possibilities to write instances: http://0pointer.de/blog/projects/instances.html
For example: /lib/systemd/system/[email protected]
looks something like this:
[Unit]
Description=Serial Getty on %I
BindTo=dev-%i.device
After=dev-%i.device systemd-user-sessions.service
[Service]
ExecStart=-/sbin/agetty -s %I 115200,38400,9600
Restart=always
RestartSec=0
So, you may start it like:
$ systemctl start [email protected]
$ systemctl start [email protected]
For systemd it will different instances:
$ systemctl status [email protected]
[email protected] - Getty on ttyUSB0
Loaded: loaded (/lib/systemd/system/[email protected]; static)
Active: active (running) since Mon, 26 Sep 2011 04:20:44 +0200; 2s ago
Main PID: 5443 (agetty)
CGroup: name=systemd:/system/[email protected]/ttyUSB0
+ 5443 /sbin/agetty -s ttyUSB0 115200,38400,9600
It also mean great possibility enable and disable it separately.
Off course it lack much power of command line parsing, but in common way it is used as some sort of config files selection. For example you may look at Fedora [email protected]: http://pkgs.fedoraproject.org/cgit/openvpn.git/tree/[email protected]
Using list comprehensions is a pretty obvious one for me. Not sure about performance, but at least things stay lists.
[x for x in a if x in b]
Or "all the x values that are in A, if the X value is in B".
Here's a good reference if you want to do it from the command line: http://linuxprograms.wordpress.com/2010/10/26/checkout-code-from-github/
Basically it's
git clone http://github.com/zoul/Finch.git
if you want to use parentheses in laravel 4 and don't forget return
In Laravel 4 (at least) you need to use $a, $b in parentheses as in the example
$a = 1;
$b = 1;
$c = 1;
$d = 1;
Model::where(function ($query) use ($a, $b) {
return $query->where('a', '=', $a)
->orWhere('b', '=', $b);
})->where(function ($query) use ($c, $d) {
return $query->where('c', '=', $c)
->orWhere('d', '=', $d);
});
<span class="txt">Some Text</span>

A very late response: We can do it simply like this:
etv.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
if (s.toString().length() > 3 && s.toString().contains(".")) {
if (s.toString().length() - s.toString().indexOf(".") > 3) {
etv.setText(s.toString().substring(0, s.length() - 1));
etv.setSelection(edtSendMoney.getText().length());
}
}
}
@Override
public void afterTextChanged(Editable arg0) {
}
}
From the docs:
_trackTrans() Sends both the transaction and item data to the Google Analytics server. This method should be called after _trackPageview(), and used in conjunction with the _addItem() and addTrans() methods. It should be called after items and transaction elements have been set up.
So, according to the docs, the items get sent when you call trackTrans(). Until you do, you can add items, but the transaction will not be sent.
Edit: Further reading led me here:
http://www.analyticsmarket.com/blog/edit-ecommerce-data
Where it clearly says you can start another transaction with an existing ID. When you commit it, the new items you listed will be added to that transaction.
This is not supported by default, but you can make it work quite easily! There are several things you'll want to encode if you want the exact same data back:
obj.tolist()
as @travelingbones mentioned. Sometimes this may be good enough.Furthermore, your numpy array could part of your data structure, e.g. you have a list with some matrices inside. For that you could use a custom encoder which basically does the above.
This should be enough to implement a solution. Or you could use json-tricks which does just this (and supports various other types) (disclaimer: I made it).
pip install json-tricks
Then
data = [
arange(0, 10, 1, dtype=int).reshape((2, 5)),
datetime(year=2017, month=1, day=19, hour=23, minute=00, second=00),
1 + 2j,
Decimal(42),
Fraction(1, 3),
MyTestCls(s='ub', dct={'7': 7}), # see later
set(range(7)),
]
# Encode with metadata to preserve types when decoding
print(dumps(data))
Yes, but what does grouping by more two columns mean? Well, it's the same as grouping by each unique pair per row. The order you list the columns changes the way the rows are sorted.
In your example, you would write
GROUP BY fV.tier_id, f.form_template_id
Meanwhile, the code
GROUP BY f.form_template_id, fV.tier_id
would give similar results, but sorted differently.
Also, bear in mind that if you need to export multiple functions at once, like actions you can use
export * from './XThingActions';
you should filter all disabled and readonly elements. i think this code should not cover buttons
$('body').on('keydown', 'input, select, textarea', function(e) {
var self = $(this),
form = self.parents('form:eq(0)'),
submit = (self.attr('type') == 'submit' || self.attr('type') == 'button'),
focusable,
next;
if (e.keyCode == 13 && !submit) {
focusable = form.find('input,a,select,button,textarea').filter(':visible:not([readonly]):not([disabled])');
next = focusable.eq(focusable.index(this)+1);
if (next.length) {
next.focus();
} else {
form.submit();
}
return false;
}
});
Just use a TreeMap
. It implements the SortedMap
interface, and thus automatically sorts the keys it contains. Your keys can just be sorted alphabetically to get the desired result, so you don't even need to provide a comparator.
HashMaps are never sorted. The only thing you coulkd do with a HashMap is get all the keys, and store them in a sorted set or in a List and sort the List.
Python 3.6 f-strings allows us to add leading zeros easily:
number = 5
print(f' now we have leading zeros in {number:02d}')
Have a look at this good post about this feature.
If you just want to make the error disappear, and you don't need the extension, then by all means comment the line out in php.ini
. But if you actually want to fix the problem here is some additional info.
There are various causes for this based on the exact module, but there are also some general guidelines.
phpinfo()
and look for extension_dir
under the Core
section. This is where your modules should be located.For instance,
/usr/lib/php/modules
for Unix/Linux.
Installation on *nix (PEAR)
Installation of extensions on Windows
Make sure you have %JAVA_HOME%
set by typing echo %JAVA_HOME%
in Command Prompt. If you don't have that set, then you need to go add your Java path to Window's Environmental Variables.
var queryDict = {}
location.search.substr(1).split("&").forEach(function(item) {
queryDict[item.split("=")[0]] = item.split("=")[1]
})
For querystring ?a=1&b=2&c=3&d&e
it returns:
> queryDict
a: "1"
b: "2"
c: "3"
d: undefined
e: undefined
See the original answer at How can I get query string values in JavaScript?
"?a=1&b=2&c=3&d&e&a=5&a=t%20e%20x%20t&e=http%3A%2F%2Fw3schools.com%2Fmy%20test.asp%3Fname%3Dståle%26car%3Dsaab"

a: ["1", "5", "t e x t"]
b: ["2"]
c: ["3"]
d: [undefined]
e: [undefined, "http://w3schools.com/my test.asp?name=ståle&car=saab"]
This is implementation of methods after decompiling.
public static bool IsNullOrEmpty(String value)
{
return (value == null || value.Length == 0);
}
public static bool IsNullOrWhiteSpace(String value)
{
if (value == null) return true;
for(int i = 0; i < value.Length; i++) {
if(!Char.IsWhiteSpace(value[i])) return false;
}
return true;
}
So it is obvious that IsNullOrWhiteSpace method also checks if value that is being passed contain white spaces.
Whitespaces refer : https://msdn.microsoft.com/en-us/library/system.char.iswhitespace(v=vs.110).aspx

After changing the ID it android.R.id.custom, I needed to add the following to get the View to display:
((View) f1.getParent()).setVisibility(View.VISIBLE);
However, this caused the new View to render in a big parent view with no background, breaking the dialog box in two parts (text and buttons, with the new View in between). I finally got the effect that I wanted by inserting my View next to the message:
LinearLayout f1 = (LinearLayout)findViewById(android.R.id.message).getParent().getParent();
I found this solution by exploring the View tree with View.getParent() and View.getChildAt(int). Not really happy about either, though. None of this is in the Android docs and if they ever change the structure of the AlertDialog, this might break.
Lambda expressions have a type of Action<parameters>
(in case they don't return a value) or Func<parameters,return>
(in case they have a return value). In your case you have two input parameters, and you need to return a value, so you should use:
Func<FullTimeJob, Student, FullTimeJob>

Just add overflow:auto; to parent div

Try this;
function X (id,parameter1,parameter2,...) {
$.ajax({
url: '@Url.Action("Actionre", "controller")',+ id,
type: "Get",
data: { parameter1: parameter1, parameter2: parameter2,...}
}).done(function(result) {
your code...
});
}
So controller method would looks like :
public ActionResult ActionName(id,parameter1, parameter2,...)
{
Your Code .......

Assuming what you need is a simple byte swap, try something like
Unsigned 16 bit conversion:
swapped = (num>>8) | (num<<8);
Unsigned 32-bit conversion:
swapped = ((num>>24)&0xff) | // move byte 3 to byte 0
((num<<8)&0xff0000) | // move byte 1 to byte 2
((num>>8)&0xff00) | // move byte 2 to byte 1
((num<<24)&0xff000000); // byte 0 to byte 3
This swaps the byte orders from positions 1234 to 4321. If your input was 0xdeadbeef
, a 32-bit endian swap might have output of 0xefbeadde
.
The code above should be cleaned up with macros or at least constants instead of magic numbers, but hopefully it helps as is
EDIT: as another answer pointed out, there are platform, OS, and instruction set specific alternatives which can be MUCH faster than the above. In the Linux kernel there are macros (cpu_to_be32 for example) which handle endianness pretty nicely. But these alternatives are specific to their environments. In practice endianness is best dealt with using a blend of available approaches
here is the sample one
div{_x000D_
width: 200px;_x000D_
height:200px;_x000D_
border:solid_x000D_

You can also use the cdata
package, which uses the concept of (transformation) control table:
# data
wide <- read.table(text="Code Country 1950 1951 1952 1953 1954
AFG Afghanistan 20,249 21,352 22,532 23,557 24,555
ALB Albania 8,097 8,986 10,058 11,123 12,246", header=TRUE, check.names=FALSE)
library(cdata)
# build control table
drec <- data.frame(
Year=as.character(1950:1954),
Value=as.character(1950:1954),
stringsAsFactors=FALSE
)
drec <- cdata::rowrecs_to_blocks_spec(drec, recordKeys=c("Code", "Country"))
# apply control table
cdata::layout_by(drec, wide)
I am currently exploring that package and find it quite accessible. It is designed for much more complicated transformations and includes the backtransformation. There is a tutorial available.
It seems that now you can just mark the method parameter with @RequestParam
and it will do the job for you.
@PostMapping( "some/request/path" )
public void someControllerMethod( @RequestParam Map<String, String> body ) {
//work with Map
}
TLDR; (semi-related to an EF editor bug in EF6/VS2012U5) if you generate the model from DB and you cannot see the attributed m:m table: Delete the two related tables -> Save .edmx -> Generate/add from database -> Save.
For those who came here wondering how to get a many-to-many relationship with attribute columns to show in the EF .edmx file (as it would currently not show and be treated as a set of navigational properties), AND you generated these classes from your database table (or database-first in MS lingo, I believe.)
Delete the 2 tables in question (to take the OP example, Member and Comment) in your .edmx and add them again through 'Generate model from database'. (i.e. do not attempt to let Visual Studio update them - delete, save, add, save)
It will then create a 3rd table in line with what is suggested here.
This is relevant in cases where a pure many-to-many relationship is added at first, and the attributes are designed in the DB later.
This was not immediately clear from this thread/Googling. So just putting it out there as this is link #1 on Google looking for the issue but coming from the DB side first.
In object oriented programming, a type includes a collection of member fields. These fields may be stored either by value or by reference (i.e., a pointer to a value).
In a shallow copy, a new instance of the type is created and the values are copied into the new instance. The reference pointers are also copied just like the values. Therefore, the references are pointing to the original objects. Any changes to the members that are stored by reference appear in both the original and the copy, since no copy was made of the referenced object.
In a deep copy, the fields that are stored by value are copied as before, but the pointers to objects stored by reference are not copied. Instead, a deep copy is made of the referenced object, and a pointer to the new object is stored. Any changes that are made to those referenced objects will not affect other copies of the object.
You can use it
inside of the shell to iterate over the next 20 results. Just type it
if you see "has more" and you will see the next 20 items.
You have 3 choices:
atoi
This is probably the fastest if you're using it in performance-critical code, but it does no error reporting. If the string does not begin with an integer, it will return 0. If the string contains junk after the integer, it will convert the initial part and ignore the rest. If the number is too big to fit in int
, the behaviour is unspecified.
sscanf
Some error reporting, and you have a lot of flexibility for what type to store (signed/unsigned versions of char/short/int/long/long long/size_t/ptrdiff_t/intmax_t
).
The return value is the number of conversions that succeed, so scanning for "%d"
will return 0 if the string does not begin with an integer. You can use "%d%n"
to store the index of the first character after the integer that's read in another variable, and thereby check to see if the entire string was converted or if there's junk afterwards. However, like atoi
, behaviour on integer overflow is unspecified.
strtol
and familyRobust error reporting, provided you set errno
to 0 before making the call. Return values are specified on overflow and errno
will be set. You can choose any number base from 2 to 36, or specify 0 as the base to auto-interpret leading 0x
and 0
as hex and octal, respectively. Choices of type to convert to are signed/unsigned versions of long/long long/intmax_t
.
If you need a smaller type you can always store the result in a temporary long
or unsigned long
variable and check for overflow yourself.
Since these functions take a pointer to pointer argument, you also get a pointer to the first character following the converted integer, for free, so you can tell if the entire string was an integer or parse subsequent data in the string if needed.
Personally, I would recommend the strtol
family for most purposes. If you're doing something quick-and-dirty, atoi might meet your needs.
As an aside, sometimes I find I need to parse numbers where leading whitespace, sign, etc. are not supposed to be accepted. In this case it's pretty damn easy to roll your own for loop, eg.,
for (x=0; (unsigned)*s-'0'<10; s++)
x=10*x+(*s-'0');
Or you can use (for robustness):
if (isdigit(*s))
x=strtol(s, &s, 10);
else /* error */
You could use a declarative module for lists of data such as query-js(*). In these situations I personally find a declarative approach less surprising
var funcs = Query.range(0,3).each(function(i){
return function() {
console.log("My value: " + i);
};
});
You could then use your second loop and get the expected result or you could do
funcs.iterate(function(f){ f(); });
(*) I'm the author of query-js and therefor biased towards using it, so don't take my words as a recommendation for said library only for the declarative approach :)
I use JQuery to perform a simple AJAX call to a dummy HTTP Handler that does nothing but keeping my Session alive:
function setHeartbeat() {
setTimeout("heartbeat()", 5*60*1000); // every 5 min
}
function heartbeat() {
$.get(
"/SessionHeartbeat.ashx",
null,
function(data) {
//$("#heartbeat").show().fadeOut(1000); // just a little "red flash" in the corner :)
setHeartbeat();
},
"json"
);
}
Session handler can be as simple as:
public class SessionHeartbeatHttpHandler : IHttpHandler, IRequiresSessionState
{
public bool IsReusable { get { return false; } }
public void ProcessRequest(HttpContext context)
{
context.Session["Heartbeat"] = DateTime.Now;
}
}
The key is to add IRequiresSessionState, otherwise Session won't be available (= null). The handler can of course also return a JSON serialized object if some data should be returned to the calling JavaScript.
Made available through web.config:
<httpHandlers>
<add verb="GET,HEAD" path="SessionHeartbeat.ashx" validate="false" type="SessionHeartbeatHttpHandler"/>
</httpHandlers>

I liked so much of this example, that I want to improve with the HTML/CSS and the beat part
change this
//$("#heartbeat").show().fadeOut(1000); // just a little "red flash" in the corner :)
into
beatHeart(2); // just a little "red flash" in the corner :)
and add
// beat the heart
// 'times' (int): nr of times to beat
function beatHeart(times) {
var interval = setInterval(function () {
$(".heartbeat").fadeIn(500, function () {
$(".heartbeat").fadeOut(500);
});
}, 1000); // beat every second
// after n times, let's clear the interval (adding 100ms of safe gap)
setTimeout(function () { clearInterval(interval); }, (1000 * times) + 100);
}
HTML and CSS
<div class="heartbeat">♥</div>
/* HEARBEAT */
.heartbeat {
position: absolute;
display: none;
margin: 5px;
color: red;
right: 0;
top: 0;
}
here is a live example for only the beating part: http://jsbin.com/ibagob/1/
I'd just like to add, and please correct me if I'm wrong, that when I embed the HTML5 version of the videos, it doesn't play ads on top.
Not sure if this will ever change. They're probably just trying to work out the best way to show ads on the HTML5 player.
In the latest version of the SDK, you would use the setBackgroundResource
method.
public void onClick(View v) {
if(v == ButtonName) {
ButtonName.setBackgroundResource(R.drawable.ImageResource);
}
}
I'd go for jpeg
. Read this post regarding image size reduction and after deciding on the technique, use ImageMagick
Hope this helps
Even I got the same issue and my mistake was that I didn't download python MSI file. You will get it here: https://www.python.org/downloads/
Once you download the msi, run the setup and that will solve the problem. After that you can go to File->Settings->Project Settings->Project Interpreter->Python Interpreters
and select the python.exe file. (This file will be available at c:\Python34) Select the python.exe file. That's it.
In the servlet code, with the instruction request.setAttribute("servletName", categoryList)
, you save your list in the request object, and use the name "servletName" for refering it.
By the way, using then name "servletName" for a list is quite confusing, maybe it's better call it "list" or something similar: request.setAttribute("list", categoryList)
Anyway, suppose you don't change your serlvet code, and store the list using the name "servletName". When you arrive to your JSP, it's necessary to retrieve the list from the request, and for that you just need the request.getAttribute(...)
method.
<%
// retrieve your list from the request, with casting
ArrayList<Category> list = (ArrayList<Category>) request.getAttribute("servletName");
// print the information about every category of the list
for(Category category : list) {
out.println(category.getId());
out.println(category.getName());
out.println(category.getMainCategoryId());
}

A variation on both @SiegeX and @mklement0's excellent contributions: mask user input; handle backspacing; but only backspace for the length of what the user has input (so we're not wiping out other characters on the same line) and handle control characters, etc... This solution was found here after so much digging!
#!/bin/bash
#
# Read and echo a password, echoing responsive 'stars' for input characters
# Also handles: backspaces, deleted and ^U (kill-line) control-chars
#
unset PWORD
PWORD=
echo -n 'password: ' 1>&2
while true; do
IFS= read -r -N1 -s char
# Note a NULL will return a empty string
# Convert users key press to hexadecimal character code
code=$(printf '%02x' "'$char") # EOL (empty char) -> 00
case "$code" in
''|0a|0d) break ;; # Exit EOF, Linefeed or Return
08|7f) # backspace or delete
if [ -n "$PWORD" ]; then
PWORD="$( echo "$PWORD" | sed 's/.$//' )"
echo -n $'\b \b' 1>&2
fi
;;
15) # ^U or kill line
echo -n "$PWORD" | sed 's/./\cH \cH/g' >&2
PWORD=''
;;
[01]?) ;; # Ignore ALL other control characters
*) PWORD="$PWORD$char"
echo -n '*' 1>&2
;;

done

You don't have to copy everything to C:\dotnet35. Usually all the files are already copied to the folder C:\Windows\WinSxS. Then the command becomes (assuming Windows was installed to C:): "Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:C:\Windows\WinSxS /LimitAccess" If not you can also point the command to the DVD directly. Then the command becomes (assuming DVD is mounted to D:): "Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:D:\sources\sxs /LimitAccess".
Simply attr-accessor
creates the getter
and setter
methods for the specified attributes
This approach is a little more elaborate. Here you store all preloaded images in a container, may be a div. And after you could show the images or move it within the DOM to the correct position.
function preloadImg(containerId, imgUrl, imageId) {
var i = document.createElement('img'); // or new Image()
i.id = imageId;
i.onload = function() {
var container = document.getElementById(containerId);
container.appendChild(this);
};
i.src = imgUrl;
}
Try it here, I have also added few comments
(I presume that you've concluded that it's an iptables problem by dropping the firewall completely (iptables -P INPUT ACCEPT; iptables -P OUTPUT ACCEPT; iptables -F) and confirmed that you can connect to the MySQL server from your Windows box?)
Some previous rule in the INPUT table is probably rejecting or dropping the packet. You can get around that by inserting the new rule at the top, although you might want to review your existing rules to see whether that's sensible:
iptables -I INPUT 1 -p tcp --dport 3306 -j ACCEPT
Note that iptables-save won't save the new rule persistently (i.e. across reboots) - you'll need to figure out something else for that. My usual route is to store the iptables-save output in a file (/etc/network/iptables.rules or similar) and then load then with a pre-up statement in /etc/network/interfaces).
Calling object.paintComponent(g)
is an error.
Instead this method is called automatically when the panel is created. The paintComponent()
method can also be called explicitly by the repaint()
method defined in Component
class.
The effect of calling repaint()
is that Swing automatically clears the graphic on the panel and executes the paintComponent
method to redraw the graphics on this panel.
So I wrote a function that would get the POST data from the php://input stream.
So the challenge here was switching to PUT, DELETE OR PATCH request method, and still obtain the post data that was sent with that request.
I'm sharing this maybe for someone with a similar challenge. The function below is what I came up with and it works. I hope it helps!
/**
* @method Post getPostData
* @return array
*
* Convert Content-Disposition to a post data
*/
function getPostData() : array
{
// @var string $input
$input = file_get_contents('php://input');
// continue if $_POST is empty
if (strlen($input) > 0 && count($_POST) == 0 || count($_POST) > 0) :
$postsize = "---".sha1(strlen($input))."---";
preg_match_all('/([-]{2,})([^\s]+)[\n|\s]{0,}/', $input, $match);
// update input
if (count($match) > 0) $input = preg_replace('/([-]{2,})([^\s]+)[\n|\s]{0,}/', '', $input);
// extract the content-disposition
preg_match_all("/(Content-Disposition: form-data; name=)+(.*)/m", $input, $matches);
// let's get the keys
if (count($matches) > 0 && count($matches[0]) > 0)
{
$keys = $matches[2];
foreach ($keys as $index => $key) :
$key = trim($key);
$key = preg_replace('/^["]/','',$key);
$key = preg_replace('/["]$/','',$key);
$key = preg_replace('/[\s]/','',$key);
$keys[$index] = $key;
endforeach;
$input = preg_replace("/(Content-Disposition: form-data; name=)+(.*)/m", $postsize, $input);
$input = preg_replace("/(Content-Length: )+([^\n]+)/im", '', $input);
// now let's get key value
$inputArr = explode($postsize, $input);
// @var array $values
$values = [];
foreach ($inputArr as $index => $val) :
$val = preg_replace('/[\n]/','',$val);
if (preg_match('/[\S]/', $val)) $values[$index] = trim($val);
endforeach;
// now combine the key to the values
$post = [];
// @var array $value
$value = [];
// update value
foreach ($values as $i => $val) $value[] = $val;
// push to post
foreach ($keys as $x => $key) $post[$key] = isset($value[$x]) ? $value[$x] : '';
if (is_array($post)) :
$newPost = [];
foreach ($post as $key => $val) :
if (preg_match('/[\[]/', $key)) :
$k = substr($key, 0, strpos($key, '['));
$child = substr($key, strpos($key, '['));
$child = preg_replace('/[\[|\]]/','', $child);
$newPost[$k][$child] = $val;
else:
$newPost[$key] = $val;
endif;
endforeach;
$_POST = count($newPost) > 0 ? $newPost : $post;
endif;
}
endif;
// return post array
return $_POST;
}
Here's a solution which will work even when JavaScript is disabled:
<form action="login.html">
<button type="submit">Login</button>
</form>
The trick is to surround the button with its own <form>
tag.
I personally prefer the <button>
tag, but you can do it with <input>
as well:
<form action="login.html">
<input type="submit" value="Login"/>
</form>
Nick Woodham's answer didn't work on OSX 10.11 El Capitan for me, but this did.
brew install openssl
CFLAGS="-I/usr/local/opt/openssl/include" pip install cryptography==0.8
In Visual Studio UML sequence this can also be described as fragments which is nicely documented here: https://msdn.microsoft.com/en-us/library/dd465153.aspx
Use jQuery ajax:
function AddToCart(id)
{
$.ajax({
url: 'urlToController',
data: { id: id }
}).done(function() {
alert('Added');
});
}
I tried nearly all suggestions. However, the only thing that really solved the issue was:
Create an .htaccess
in the same folder where your PHP file lies.
Add this line to the htaccess:
Header always unset X-Frame-Options
Embedding the PHP by an iframe from another domain should work afterwards.
Additionally you could add in the beginning of your PHP file:
header('X-Frame-Options: ALLOW');
Which was, however, not necessary in my case.
Application.Sum often does not work well in my experience (or at least the VBA developer environment does not like it for whatever reason).
The function that works best for me is Excel.WorksheetFunction.Sum()
Example:
Dim Report As Worksheet 'Set up your new worksheet variable.
Set Report = Excel.ActiveSheet 'Assign the active sheet to the variable.
Report.Cells(11, 1).Value = Excel.WorksheetFunction.Sum(Report.Range("A1:A10")) 'Add the function result.
The other method which you were looking for I think is to place the function directly into the cell. This can be done by inputting the function string into the cell value. Here is an example that provides the same result as above, except the cell value is given the function and not the result of the function:
Dim Report As Worksheet 'Set up your new worksheet variable.
Set Report = Excel.ActiveSheet 'Assign the active sheet to the variable.
Report.Cells(11, 1).Value = "=Sum(A1:A10)" 'Add the function.
If you just need to search for one string within another, use the index
function (or rindex
if you want to start scanning from the end of the string):
if (index($string, $substring) != -1) {
print "'$string' contains '$substring'\n";
}
To search a string for a pattern match, use the match operator m//
:
if ($string =~ m/pattern/) {
print "'$string' matches the pattern\n";
}
Preferred way to change the appearance/whatever of row views once the ListView is drawn is to change something in the data ListView draws from (the array of objects that is passed into your Adapter) and make sure to account for that in your getView() function, then redraw the ListView by calling
notifyDataSetChanged();
EDIT: while there is a way to do this, if you need to do this chances are doing something wrong. While are few edge cases I can think about, generally using notifyDataSetChanged()
and other built in mechanisms is a way to go.
EDIT 2: One of the common mistakes people make is trying to come up with their own way to respond to user clicking/selecting a row in the ListView, as in one of the comments to this post. There is an existing way to do this. Here's how:
mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
/* Parameters
parent: The AdapterView where the click happened.
view: The view within the AdapterView that was clicked (this will be a view provided by the adapter)
position: The position of the view in the adapter.
id: The row id of the item that was clicked. */
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//your code here
}
});
ListView has a lot of build-in functionality and there is no need to reinvent the wheel for simpler cases. Since ListView extends AdapterView, you can set the same Listeners, such as OnItemClickListener as in the example above.
Here's where it gets confusing, the text states "If the balance factor of R is 1, it means the insertion occurred on the (external) right side of that node and a left rotation is needed". But from m understanding the text said (as I quoted) that if the balance factor was within [-1, 1] then there was no need for balancing?
Okay, epiphany time.
Consider what a rotation does. Let's think about a left rotation.
P = parent
O = ourself (the element we're rotating)
RC = right child
LC = left child (of the right child, not of ourself)
P 10
\ \
O 15
\ \
RC 20
/ /
LC 18
?
P 10
\ \
RC 20
/ /
O 15
\ \
LC 18
basically, what happens is;
1. our right child moves into our position
2. we become the left child of our right child
3. our right child's left child becomes our right
Now, the big thing you have to notice here - this left rotation HAS NOT CHANGED THE DEPTH OF THE TREE. We're no more balanced for having done it.
But - and here's the magic in AVL - if we rotated the right child to the right FIRST, what we'd have is this...
P
\
O
\
LC
\
RC
And NOW if we rotate O left, what we get is this...
P
\
LC
/ \
O RC
Magic! we've managed to get rid of a level of the tree - we've made the tree balanced.
Balancing the tree means getting rid of excess depth, and packing the upper levels more completely - which is exactly what we've just done.
That whole stuff about single/double rotations is simply that you have to have your subtree looking like this;
P
\
O
\
LC
\
RC
before you rotate - and you may have to do a right rotate to get into that state. But if you're already in that state, you only need to do the left rotate.
Here are the changes I had to make to deliver PDFs for the django-publications app, using Django 1.10.6:
Used the same definitions for media directories as you, in settings.py
:
MEDIA_ROOT = '/home/user/mysite/media/'
MEDIA_URL = '/media/'
As provided by @thisisashwanipandey, in the project's main urls.py
:
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
# ... the rest of your URLconf goes here ...
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
and a modification of the answer provided by @r-allela, in settings.py
:
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates')],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
# ... the rest of your context_processors goes here ...
'django.template.context_processors.media',
],
},
},
]
There is a really nice, easy to use, lightweight (uses native browser events for detection) plugin for both basic JavaScript and for jQuery that was released this year. It performs perfectly:
A bit more along the same lines
attrs <- {}
attrs.a <- 1
f <- function(d) {
attrs.a <- d
}
f(20)
print(attrs.a)
will print "1"
attrs <- {}
attrs.a <- 1
f <- function(d) {
attrs.a <<- d
}
f(20)
print(attrs.a)
Will print "20"
The easiest way is to not store the count, relying on the COUNT aggregate function to reflect the value as it is in the database:
SELECT c.category_name,
COUNT(p.post_id) AS num_posts
FROM CATEGORY c
LEFT JOIN POSTS p ON p.category_id = c.category_id
You can create a view to house the query mentioned above, so you can query the view just like you would a table...
But if you're set on storing the number, use:
UPDATE CATEGORY
SET count = count + 1
WHERE category_id = ?
..replacing "?" with the appropriate value.
You can use the hide
and show
functions of jquery. Examples
In your case just set $('#msform').hide()
or $('#msform').show()
Suppose a 9800GT GPU:
https://www.tutorialspoint.com/cuda/cuda_threads.htm
A block cannot have more active threads than 512 therefore __syncthreads
can only synchronize limited number of threads. i.e. If you execute the following with 600 threads:
func1();
__syncthreads();
func2();
__syncthreads();
then the kernel must run twice and the order of execution will be:
Note:
The main point is __syncthreads
is a block-wide operation and it does not synchronize all threads.
I'm not sure about the exact number of threads that __syncthreads
can synchronize, since you can create a block with more than 512 threads and let the warp handle the scheduling. To my understanding it's more accurate to say: func1 is executed at least for the first 512 threads.
Before I edited this answer (back in 2010) I measured 14x8x32 threads were synchronized using __syncthreads
.
I would greatly appreciate if someone test this again for a more accurate piece of information.
One thing I've not seen anyone mention: the JSON file must have one line specifying the index the next line belongs to, for every line of the "pure" JSON file.
I.E.
{"index":{"_index":"shakespeare","_type":"act","_id":0}}
{"line_id":1,"play_name":"Henry IV","speech_number":"","line_number":"","speaker":"","text_entry":"ACT I"}
Without that, nothing works, and it won't tell you why

this is just as a side note, but generally what you want to do is keep size on the Session and ViewState small. I generally just store IDs and small amounts of packets in Session and ViewState.
for instance if you want to pass large chunks of data from one page to another, you can store an ID in the querystring and use that ID to either get data from a database or a file.
PS: but like I said, this might be totally unrelated to your query :)
You could try to kill the PHP process:
exec('kill -9 ' . getmypid());
According to the above answers setdefault() method worked for me.
old_attr_name = mydict.setdefault(key, attr_name)
if attr_name != old_attr_name:
raise RuntimeError(f"Key '{key}' duplication: "
f"'{old_attr_name}' and '{attr_name}'.")
Though this solution is not generic. Just suited me in this certain case. The exact solution would be checking for the key
first (as was already advised), but with setdefault()
we avoid one extra lookup on the dictionary, that is, though small, but still a performance gain.
In your concrete example the problem is that you don't use this construct correctly:
@JsonSubTypes({ @JsonSubTypes.Type(value = MyAbstractClass.class, name = "MyAbstractClass") })
@JsonSubTypes.Type
should contain the actual non-abstract subtypes of your abstract class.
Therefore if you have:
abstract class Parent
and the concrete subclasses
Ch1 extends Parent
and
Ch2 extends Parent
Then your annotation should look like:
@JsonSubTypes({
@JsonSubTypes.Type(value = Ch1.class, name = "ch1"),
@JsonSubTypes.Type(value = Ch2.class, name = "ch2")
})
Here name
should match the value of your 'discriminator':
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME,
include = JsonTypeInfo.As.WRAPPER_OBJECT,
property = "type")
in the property
field, here it is equal to type
. So type
will be the key and the value you set in name
will be the value.
Therefore, when the json string comes if it has this form:
{
"type": "ch1",
"other":"fields"
}
Jackson will automatically convert this to a Ch1
class.
If you send this:
{
"type": "ch2",
"other":"fields"
}
You would get a Ch2
instance.
Item collection.
$_item->product_type;
$_item->getId()
Product :
$product->getTypeId();
$product->getId()
You want to take advantage of the inserted logical table that is available in the context of a trigger. It matches the schema for the table that is being inserted to and includes the row(s) that will be inserted (in an update trigger you have access to the inserted and deleted logical tables which represent the the new and original data respectively.)
So to insert Employee / Department pairs that do not currently exist you might try something like the following.
CREATE TRIGGER trig_Update_Employee
ON [EmployeeResult]
FOR INSERT
AS
Begin
Insert into Employee (Name, Department)
Select Distinct i.Name, i.Department
from Inserted i
Left Join Employee e
on i.Name = e.Name and i.Department = e.Department
where e.Name is null
End
Did you try InputMethodManager.SHOW_IMPLICIT
in first window.
and for hiding in second window use InputMethodManager.HIDE_IMPLICIT_ONLY
EDIT :
If its still not working then probably you are putting it at the wrong place. Override onFinishInflate()
and show/hide there.
@override
public void onFinishInflate() {
/* code to show keyboard on startup */
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(mUserNameEdit, InputMethodManager.SHOW_IMPLICIT);
}
Use something like
ALTER TABLE T2
ADD CONSTRAINT fk_employee
FOREIGN KEY (employeeID)
REFERENCES T1 (employeeID)
ON DELETE CASCADE;
Fill in the correct column names and you should be set. As mark_s correctly stated, if you have already a foreign key constraint in place, you maybe need to delete the old one first and then create the new one.
You could simply look in the Active Record Rake tasks as that is where I believe they live as in this file. https://github.com/rails/rails/blob/fe1f4b2ad56f010a4e9b93d547d63a15953d9dc2/activerecord/lib/active_record/tasks/database_tasks.rb
What they do is your question right?
That depends on where they come from and this is just and example to show that they vary depending upon the task. Here we have a different file full of tasks.
https://github.com/rails/rails/blob/fe1f4b2ad56f010a4e9b93d547d63a15953d9dc2/activerecord/Rakefile
which has these tasks.
namespace :db do
task create: ["db:mysql:build", "db:postgresql:build"]
task drop: ["db:mysql:drop", "db:postgresql:drop"]
end
This may not answer your question but could give you some insight into go ahead and look the source over especially the rake files and tasks. As they do a pretty good job of helping you use rails they don't always document the code that well. We could all help there if we know what it is supposed to do.
The var
keyword in C#'s main benefit is to enhance readability, not functionality. Technically, the var
keywords allows for some other unlocks (e.g. use of anonymous objects), but that seems to be outside the scope of this question. Every variable declared with the var
keyword has a type. For instance, you'll find that the following code outputs "String".
var myString = "";
Console.Write(myString.GetType().Name);
Furthermore, the code above is equivalent to:
String myString = "";
Console.Write(myString.GetType().Name);
The var
keyword is simply C#'s way of saying "I can figure out the type for myString
from the context, so don't worry about specifying the type."
var myVariable = (MyType)null
or MyType myVariable = null
should work because you are giving the C# compiler context to figure out what type myVariable
should will be.

As other answers have mentioned, the following calls will compute the hash:
MD5Context md5;
MD5Init(&md5);
MD5Update(&md5, data, datalen);
MD5Final(digest, &md5);
The purpose of splitting it up into that many functions is to let you stream large datasets.
For example, if you're hashing a 10GB file and it doesn't fit into ram, here's how you would go about doing it. You would read the file in smaller chunks and call MD5Update
on them.
MD5Context md5;
MD5Init(&md5);
fread(/* Read a block into data. */)
MD5Update(&md5, data, datalen);
fread(/* Read the next block into data. */)
MD5Update(&md5, data, datalen);
fread(/* Read the next block into data. */)
MD5Update(&md5, data, datalen);
...
// Now finish to get the final hash value.
MD5Final(digest, &md5);
String extension = com.google.common.io.Files.getFileExtension("fileName.jpg");
Give the UL an ID and use the getElementById function:
<html>
<body>
<script>
function toggledisplay(elementID)
{
(function(style) {
style.display = style.display === 'none' ? '' : 'none';
})(document.getElementById(elementID).style);
}
</script>
<a href="#" title="Show Tags" onClick="toggledisplay('changethis');">Show All Tags</a>
<ul class="subforums" id="changethis" style="overflow-x: visible; overflow-y: visible; ">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
</body>
</html>
For Rails 4.x the log level is configured a bit different than in Rails 3.x
Add this to config/environment/test.rb
# Enable stdout logger
config.logger = Logger.new(STDOUT)
# Set log level
config.log_level = :ERROR
The logger level is set on the logger instance from config.log_level
at: https://github.com/rails/rails/blob/v4.2.4/railties/lib/rails/application/bootstrap.rb#L70
Environment variable
As a bonus, you can allow overwriting the log level using an environment variable with a default value like so:
# default :ERROR
config.log_level = ENV.fetch("LOG_LEVEL", "ERROR")
And then running tests from shell:
# Log level :INFO (the value is uppercased in bootstrap.rb)
$ LOG_LEVEL=info rake test
# Log level :ERROR
$ rake test
It could happen after you update your php version, for instance if you upgrade from php5.6 to php7.1 you need to run these commands:
sudo apt-get install php7.1-mbstring
sudo service apache2 restart
If your destination version is different you need to check if the mbstring package exsit or not, an example for php7.0:
sudo apt-cache search php7.0-mbstring
I found it useful to first check existence of all modules that you working with, then performing an upgrade, in addition to that update phpmyadmin after upgrading your php is a good idea
To update your existing project to another project, you can use this command line:
gcloud projects update PROJECT_ID --name=NAME
NAME: will be the new name of your project.
The most important thing to remember, when you get a NULL result from JSON data that is valid is to use the following command:
json_last_error_msg();
Ie.
var_dump(json_last_error_msg());
string(53) "Control character error, possibly incorrectly encoded"
You then fix that with:
$new_json = preg_replace('/[[:cntrl:]]/', '', $json);

It may well be that you're running WordPress core tests, and have recently upgraded your PhpUnit to version 6. If that's the case, then the recent change to namespacing in PhpUnit will have broken your code.
Fortunately, there's a patch to the core tests at https://core.trac.wordpress.org/changeset/40547 which will work around the problem. It also includes changes to travis.yml, which you may not have in your setup; if that's the case then you'll need to edit the .diff file to ignore the Travis patch.
Edit the patch file to remove the Travis part of the patch if you don't need that. Delete from the top of the file to just above this line:
Index: /branches/4.7/tests/phpunit/includes/bootstrap.php
Save the diff in the directory above your /includes/ directory - in my case this was the Wordpress directory itself
Use the Unix patch tool to patch the files. You'll also need to strip the first few slashes to move from an absolute to a relative directory structure. As you can see from point 3 above, there are five slashes before the include directory, which a -p5 flag will get rid of for you.
$ cd [WORDPRESS DIRECTORY]
$ patch -p5 < changeset_40547.diff
After I did this my tests ran correctly again.
The below code works for me -:
jQuery('[id^=select_] > option').each(function(){
if (this.text.toLowerCase()=='text'){
jQuery('[id^=select_]').val(this.value);
}
});
jQuery('[id^=select_]') - This allows you to select drop down where ID of the drop down starts from select_
Hope the above helps!
Cheers S
Use replace()
s = s.replace("'", "\\'");
output:
You\'ll be totally awesome, I\'m really terrible
To provide numerical values rounded to two decimal places but right-padded with zeros if required I have:
DECLARE @value = 20.1
SET @value = ROUND(@value,2) * 100
PRINT LEFT(CAST(@value AS VARCHAR(20)), LEN(@value)-2) + '.' + RIGHT(CAST(@value AS VARCHAR(20)),2)
If anyone can think of a neater way, that would be appreciated - the above seems clumsy.
Note: in this instance, I'm using SQL Server to email reports in HTML format and so wish to format the information without involving an additional tool to parse the data.
Quick example using company1
from your question, with python3.
import pickle
# Save the file
pickle.dump(company1, file = open("company1.pickle", "wb"))
# Reload the file
company1_reloaded = pickle.load(open("company1.pickle", "rb"))
However, as this answer noted, pickle often fails. So you should really use dill
.
import dill
# Save the file
dill.dump(company1, file = open("company1.pickle", "wb"))
# Reload the file
company1_reloaded = dill.load(open("company1.pickle", "rb"))
DateTime newDateTime = dtReceived.Value.Date.Add(TimeSpan.Parse(dtReceivedTime.Value.ToShortTimeString()));
Alternate solution can be:
baseKey hKeyLocalMachine = baseKey.HKEY_LOCAL_MACHINE;
uint value = (uint)hKeyLocalMachine;
Or just:
uint value = (uint)baseKey.HKEY_LOCAL_MACHINE;
DECIMAL
has two parts: Precision
and Scale
. So part of your query will look like this:
CAST((COUNT(*) * 1.5) AS DECIMAL(8,2))
Precision
represents the number of significant digits that are stored for values.
Scale
represents the number of digits that can be stored following the decimal point.
int i = (int)d;
will give you the number rounded down.
If you want to round to the nearest even number (i.e. >.5 will round up) you can use
int i = (int)Math.Round(d, MidpointRounding.ToEven);
In general you can cast between all the numerical types in C#. If there is no information that will be lost during the cast you can do it implicitly:
int i = 10;
decimal d = i;
though you can still do it explicitly if you wish:
int i = 10;
decimal d = (decimal)i;
However, if you are going to be losing information through the cast you must do it explicitly (to show you are aware you may be losing information):
decimal d = 10.5M;
int i = (int)d;
Here you are losing the ".5". This may be fine, but you must be explicit about it and make an explicit cast to show you know you may be losing the information.
First and foremost, I highly recommend you buy the PDF/E-Book from PHP Architect. It's US$20, but is the only straightforward "Here's how Magento works" resource I've been able to find. I've also started writing Magento tutorials at my own website.
Second, if you have a choice, and aren't an experienced programmer or don't have access to an experienced programmer (ideally in PHP and Java), pick another cart. Magento is well engineered, but it was engineered to be a shopping cart solution that other programmers can build modules on top of. It was not engineered to be easily understood by people who are smart, but aren't programmers.
Third, Magento MVC is very different from the Ruby on Rails, Django, CodeIgniter, CakePHP, etc. MVC model that's popular with PHP developers these days. I think it's based on the Zend model, and the whole thing is very Java OOP-like. There's two controllers you need to be concerned about. The module/frontName controller, and then the MVC controller.
Fourth, the Magento application itself is built using the same module system you'll be using, so poking around the core code is a useful learning tactic. Also, a lot of what you'll be doing with Magento is overriding existing classes. What I'm covering here is creating new functionality, not overriding. Keep this in mind when you're looking at the code samples out there.
I'm going to start with your first question, showing you how to setup a controller/router to respond to a specific URL. This will be a small novel. I might have time later for the model/template related topics, but for now, I don't. I will, however, briefly speak to your SQL question.
Magento uses an EAV database architecture. Whenever possible, try to use the model objects the system provides to get the information you need. I know it's all there in the SQL tables, but it's best not to think of grabbing data using raw SQL queries, or you'll go mad.
Final disclaimer. I've been using Magento for about two or three weeks, so caveat emptor. This is an exercise to get this straight in my head as much as it is to help Stack Overflow.
All additions and customizations to Magento are done through modules. So, the first thing you'll need to do is create a new module. Create an XML file in app/modules
named as follows
cd /path/to/store/app
touch etc/modules/MyCompanyName_HelloWorld.xml
<?xml version="1.0"?>
<config>
<modules>
<MyCompanyName_HelloWorld>
<active>true</active>
<codePool>local</codePool>
</MyCompanyName_HelloWorld>
</modules>
</config>
MyCompanyName is a unique namespace for your modifications, it doesn't have to be your company's name, but that the recommended convention my magento. HelloWorld
is the name of your module.
Now that the module file is in place, we'll need to let Magento know about it (and check our work). In the admin application
Now, we make sure that Magento knows about the module
If you can live with the performance slow down, you might want to turn off the application cache while developing/learning. Nothing is more frustrating then forgetting the clear out the cache and wondering why your changes aren't showing up.
Next, we'll need to setup a directory structure for the module. You won't need all these directories, but there's no harm in setting them all up now.
mkdir -p app/code/local/MyCompanyName/HelloWorld/Block
mkdir -p app/code/local/MyCompanyName/HelloWorld/controllers
mkdir -p app/code/local/MyCompanyName/HelloWorld/Model
mkdir -p app/code/local/MyCompanyName/HelloWorld/Helper
mkdir -p app/code/local/MyCompanyName/HelloWorld/etc
mkdir -p app/code/local/MyCompanyName/HelloWorld/sql
And add a configuration file
touch app/code/local/MyCompanyName/HelloWorld/etc/config.xml
and inside the configuration file, add the following, which is essentially a "blank" configuration.
<?xml version="1.0"?>
<config>
<modules>
<MyCompanyName_HelloWorld>
<version>0.1.0</version>
</MyCompanyName_HelloWorld>
</modules>
</config>
Oversimplifying things, this configuration file will let you tell Magento what code you want to run.
Next, we need to setup the module's routers. This will let the system know that we're handling any URLs in the form of
http://example.com/magento/index.php/helloworld
So, in your configuration file, add the following section.
<config>
<!-- ... -->
<frontend>
<routers>
<!-- the <helloworld> tagname appears to be arbitrary, but by
convention is should match the frontName tag below-->
<helloworld>
<use>standard</use>
<args>
<module>MyCompanyName_HelloWorld</module>
<frontName>helloworld</frontName>
</args>
</helloworld>
</routers>
</frontend>
<!-- ... -->
</config>
What you're saying here is "any URL with the frontName of helloworld ...
http://example.com/magento/index.php/helloworld
should use the frontName controller MyCompanyName_HelloWorld".
So, with the above configuration in place, when you load the helloworld page above, you'll get a 404 page. That's because we haven't created a file for our controller. Let's do that now.
touch app/code/local/MyCompanyName/HelloWorld/controllers/IndexController.php
Now try loading the page. Progress! Instead of a 404, you'll get a PHP/Magento exception
Controller file was loaded but class does not exist
So, open the file we just created, and paste in the following code. The name of the class needs to be based on the name you provided in your router.
<?php
class MyCompanyName_HelloWorld_IndexController extends Mage_Core_Controller_Front_Action{
public function indexAction(){
echo "We're echoing just to show that this is what's called, normally you'd have some kind of redirect going on here";
}
}
What we've just setup is the module/frontName controller.
This is the default controller and the default action of the module.
If you want to add controllers or actions, you have to remember that the tree first part of a Magento URL are immutable they will always go this way http://example.com/magento/index.php/frontName/controllerName/actionName
So if you want to match this url
http://example.com/magento/index.php/helloworld/foo
You will have to have a FooController, which you can do this way :
touch app/code/local/MyCompanyName/HelloWorld/controllers/FooController.php
<?php
class MyCompanyName_HelloWorld_FooController extends Mage_Core_Controller_Front_Action{
public function indexAction(){
echo 'Foo Index Action';
}
public function addAction(){
echo 'Foo add Action';
}
public function deleteAction(){
echo 'Foo delete Action';
}
}
Please note that the default controller IndexController and the default action indexAction can by implicit but have to be explicit if something come after it.
So http://example.com/magento/index.php/helloworld/foo
will match the controller FooController and the action indexAction and NOT the action fooAction of the IndexController. If you want to have a fooAction, in the controller IndexController you then have to call this controller explicitly like this way :
http://example.com/magento/index.php/helloworld/index/foo
because the second part of the url is and will always be the controllerName.
This behaviour is an inheritance of the Zend Framework bundled in Magento.
You should now be able to hit the following URLs and see the results of your echo statements
http://example.com/magento/index.php/helloworld/foo
http://example.com/magento/index.php/helloworld/foo/add
http://example.com/magento/index.php/helloworld/foo/delete
So, that should give you a basic idea on how Magento dispatches to a controller. From here I'd recommended poking at the existing Magento controller classes to see how models and the template/layout system should be used.

This is how session state works in ASP.NET and ASP.NET MVC:
ASP.NET Session State Overview
Basically, you do this to store a value in the Session object:
Session["FirstName"] = FirstNameTextBox.Text;
To retrieve the value:
var firstName = Session["FirstName"];
Here's an alternative method using the inbuilt properties of the anchor HTML element:
var a = document.createElement('a'),_x000D_

getHrefWithUpdatedQueryString = function(param, value) {_x000D_
return updatedQueryString(window.location.href, param, value);_x000D_

_x000D_
updatedQueryString = function(url, param, value) {_x000D_

This may now be the easiest, as of v1.32:
{
"key": "ctrl+shift+t",
"command": "workbench.action.terminal.sendSequence",
"args": { "text": "node '${file}'\u000D" }
}
Use your own keybinding.
See Release notes: sendSequence and variables.
With vscode v1.32 you can sendSequence
to the terminal using variables like ${file}
, which is the current file. If you want some other path there, replace ${file} with your pathname in the keybinding above.
The \u000D
is a return so it will run immediately.
I added '
s around the ${file}
variable in case your file path has spaces in it,
like c:Users\Some Directory\fileToRun
Or like df.filter($"friend_id".isNotNull)
item = objects.Find(obj => obj.property==myValue);
Reproducing tim_yates answer on current hardware and adding leftShift() and concat() method to check the finding:
'String leftShift' {
foo << bar << baz
}
'String concat' {
foo.concat(bar)
.concat(baz)
.toString()
}
The outcome shows concat() to be the faster solution for a pure String, but if you can handle GString somewhere else, GString template is still ahead, while honorable mention should go to leftShift() (bitwise operator) and StringBuffer() with initial allocation:

I actually prefer the approach given as the answer here: Is there a better alternative than this to 'switch on type'?
There is however a good argument about not implementing any type comparison methids in an object oriented language like C#. You could as an alternative extend and add extra required functionality using inheritance.
This point was discussed in the comments of the authors blog here: http://blogs.msdn.com/b/jaredpar/archive/2008/05/16/switching-on-types.aspx#8553535
I found this an extremely interesting point which changed my approach in a similar situation and only hope this helps others.
Kind Regards, Wayne
You can suppress the space by printing an empty string to stdout between the print
statements.
>>> import sys
>>> for i in range(20):
... print 'a',
... sys.stdout.write('')
...
aaaaaaaaaaaaaaaaaaaa
However, a cleaner solution is to first build the entire string you'd like to print and then output it with a single print
statement.
Tomcat can work in 2 modes:
Tomcat 7 is BIO by default, although consensus seems to be "don't use Bio because Nio is better in every way". You set this using the protocol
parameter in the server.xml
file.
HTTP/1.1
or org.apache.coyote.http11.Http11Protocol
org.apache.coyote.http11.Http11NioProtocol
If you're using BIO then I believe they should be more or less the same.
If you're using NIO then actually "maxConnections=1000" and "maxThreads=10" might even be reasonable. The defaults are maxConnections=10,000 and maxThreads=200. With NIO, each thread can serve any number of connections, switching back and forth but retaining the connection so you don't need to do all the usual handshaking which is especially time-consuming with HTTPS but even an issue with HTTP. You can adjust the "keepAlive" parameter to keep connections around for longer and this should speed everything up.
A slightly modified version of Brian's answer allows optional management of read start, This seems to be the easiest method. probably not the most efficient, but easy to understand and use.
Public Function ReadAll(ByVal memStream As MemoryStream, Optional ByVal startPos As Integer = 0) As String
' reset the stream or we'll get an empty string returned
' remember the position so we can restore it later
Dim Pos = memStream.Position
memStream.Position = startPos
Dim reader As New StreamReader(memStream)
Dim str = reader.ReadToEnd()
' reset the position so that subsequent writes are correct
memStream.Position = Pos
Return str
End Function
Another, very simple way of monitoring tables is table versioning. The system is proven working in constructions such as DNS synchronization. To make it work you create a table containing table names and table versions as decimal
or bigint.
In each table that you need monitored, create trigger on insert, update and delete that will increment appropriate table version in versioning table when executed. If you expect any of the monitored tables to be altered often, you need to provision for version reusing. Finally, in your application, every time you query monitored table, you also query its version and store it. When you go to alter the monitored table from your app, you first query its current version and process the change only if the version is unchanged. You can have stored proc on sql server do that work for you.
This is extremely simple but proven solid solution. It has specific functional use (to ensure data consistency) and is light on resources (you do not raise brokered events that you would not watch for) but needs application to actively check for changes rather than passively wait for event to happen.
The following query works. It uses each group to do the select instead of SelectMany
. SelectMany
works on each element from each collection. For example, in your query you have a result of 2 collections. SelectMany
gets all the results, a total of 3, instead of each collection. The following code works on each IGrouping
in the select portion to get your aggregate operations working correctly.
var results = from line in Lines
group line by line.ProductCode into g
select new ResultLine {
ProductName = g.First().Name,
Price = g.Sum(pc => pc.Price).ToString(),
Quantity = g.Count().ToString(),
};
The closed hand cursor is not 16x16. If you would need them in the same dimensions, here you have both of them in 16x16 px
Or if you need original cursors:
https://www.google.com/intl/en_ALL/mapfiles/openhand.cur https://www.google.com/intl/en_ALL/mapfiles/closedhand.cur
I would recommend using Apache Commons Collections
which implements it quite ok and well documented:
/**
* Null-safe check if the specified collection is empty.
* <p>
* Null returns true.
*
* @param coll the collection to check, may be null
* @return true if empty or null
* @since Commons Collections 3.2
*/
public static boolean isEmpty(Collection coll) {
return (coll == null || coll.isEmpty());
}
My two cents.... It's irrelevant whether JavaScript passes parameters by reference or value. What really matters is assignment vs. mutation.
I wrote a longer, more detailed explanation in this link.
When you pass anything (whether that be an object or a primitive), all JavaScript does is assign a new variable while inside the function... just like using the equal sign (=
).
How that parameter behaves inside the function is exactly the same as it would behave if you just assigned a new variable using the equal sign... Take these simple examples.
var myString = 'Test string 1';
// Assignment - A link to the same place as myString
var sameString = myString;
// If I change sameString, it will not modify myString,
// it just re-assigns it to a whole new string
sameString = 'New string';
console.log(myString); // Logs 'Test string 1';
console.log(sameString); // Logs 'New string';
_x000D_
If I were to pass myString
as a parameter to a function, it behaves as if I simply assigned it to a new variable. Now, let's do the same thing, but with a function instead of a simple assignment
function myFunc(sameString) {
// Reassignment... Again, it will not modify myString
sameString = 'New string';
}
var myString = 'Test string 1';
// This behaves the same as if we said sameString = myString
myFunc(myString);
console.log(myString); // Again, logs 'Test string 1';
_x000D_
The only reason that you can modify objects when you pass them to a function is because you are not reassigning... Instead, objects can be changed or mutated.... Again, it works the same way.
var myObject = { name: 'Joe'; }
// Assignment - We simply link to the same object
var sameObject = myObject;
// This time, we can mutate it. So a change to myObject affects sameObject and visa versa
myObject.name = 'Jack';
console.log(sameObject.name); // Logs 'Jack'
sameObject.name = 'Jill';
console.log(myObject.name); // Logs 'Jill'
// If we re-assign it, the link is lost
sameObject = { name: 'Howard' };
console.log(myObject.name); // Logs 'Jill'
If I were to pass myObject
as a parameter to a function, it behaves as if I simply assigned it to a new variable. Again, the same thing with the exact same behavior but with a function.
function myFunc(sameObject) {
// We mutate the object, so the myObject gets the change too... just like before.
sameObject.name = 'Jill';
// But, if we re-assign it, the link is lost
sameObject = {
name: 'Howard'
};
}
var myObject = {
name: 'Joe'
};
// This behaves the same as if we said sameObject = myObject;
myFunc(myObject);
console.log(myObject.name); // Logs 'Jill'
_x000D_
Every time you pass a variable to a function, you are "assigning" to whatever the name of the parameter is, just like if you used the equal =
sign.
Always remember that the equals sign =
means assignment.
And passing a parameter to a function also means assignment.
They are the same and the two variables are connected in exactly the same way.
The only time that modifying a variable affects a different variable is when the underlying object is mutated.
There is no point in making a distinction between objects and primitives, because it works the same exact way as if you didn't have a function and just used the equal sign to assign to a new variable.
The other simple way, use docker-compose with the following lines:
mysql:
from: mysql:5.7
volumes:
- ./database:/tmp/database
command: mysqld --init-file="/tmp/database/install_db.sql"
Put your database schema into the ./database/install_db.sql. Every time when you build up your container, the install_db.sql will be executed.
The easiest solution is to copy/paste every sql files in one.
You can't add some sql markup for file importation (the imported files will be in your computer, not in the server, and I don't think MySQL manage some import markup for external sql files).
The other answers cover how to do std dev in python sufficiently, but no one explains how to do the bizarre traversal you've described.
I'm going to assume A-Z is the entire population. If not see Ome's answer on how to inference from a sample.
So to get the standard deviation/mean of the first digit of every list you would need something like this:
#standard deviation
numpy.std([A_rank[0], B_rank[0], C_rank[0], ..., Z_rank[0]])
#mean
numpy.mean([A_rank[0], B_rank[0], C_rank[0], ..., Z_rank[0]])
To shorten the code and generalize this to any nth digit use the following function I generated for you:
def getAllNthRanks(n):
return [A_rank[n], B_rank[n], C_rank[n], D_rank[n], E_rank[n], F_rank[n], G_rank[n], H_rank[n], I_rank[n], J_rank[n], K_rank[n], L_rank[n], M_rank[n], N_rank[n], O_rank[n], P_rank[n], Q_rank[n], R_rank[n], S_rank[n], T_rank[n], U_rank[n], V_rank[n], W_rank[n], X_rank[n], Y_rank[n], Z_rank[n]]
Now you can simply get the stdd and mean of all the nth places from A-Z like this:
#standard deviation
numpy.std(getAllNthRanks(n))
#mean
numpy.mean(getAllNthRanks(n))
This should work, at least according to the Search Filter Syntax article on MSDN network.
The "hang-up" you have noticed is probably just a delay. Try running the same query with narrower scope (for example the specific OU where the test object is located), as it may take very long time for processing if you run it against all AD objects.
You may also try separating the filter into two parts:
(|(displayName=*searchstring)(displayName=searchstring*))
You want to navigate through the entire linked list using a loop and checking the "next" value for each node. The last node will be the one whose next value is null. Simply make this node's next value a new node which you create with the input data.
node temp = first; // starts with the first node.
while (temp.next != null)
{
temp = temp.next;
}
temp.next = new Node(header, x);
That's the basic idea. This is of course, pseudo code, but it should be simple enough to implement.
In sake of readability it should be something like
<?php
$countries = $myaddress->get_countries();
foreach($countries as $value) {
$selected ='';
if($value=='United States') $selected ='selected="selected"';
echo '<option value="'.$value.'"'.$selected.'>'.$value.'</option>';
}
?>
desire to stuff EVERYTHING in a single line is a decease, man. Write distinctly.
But there is another way, a better one. There is no need to use echo at all. Learn to use templates. Prepare your data first, and display it only then ready.
Business logic part:
$countries = $myaddress->get_countries();
$selected_country = 1;
Template part:
<? foreach($countries as $row): ?>
<option value="<?=$row['id']?>"<? if ($row['id']==$current_country):> "selected"><? endif ?>
<?=$row['name']?>
</option>
<? endforeach ?>
Trying to write a REST API from scratch is not a simple task. There are many issues to factor and you will need to write a lot of code to process requests and data coming from the caller, authentication, retrieval of data and sending back responses.
Your best bet is to use a framework that already has this functionality ready and tested for you.
Some suggestions are:
Phalcon - REST API building - Easy to use all in one framework with huge performance
Apigility - A one size fits all API handling framework by Zend Technologies
Laravel API Building Tutorial
and many more. Simple searches on Bitbucket/Github will give you a lot of resources to start with.
You are using two WHERE
clauses but only one is allowed. Use it like this:
SELECT table1.f_id FROM table1
INNER JOIN table2 ON table2.f_id = table1.f_id
WHERE
table1.f_com_id = '430'
AND table1.f_status = 'Submitted'
AND table2.f_type = 'InProcess'
It sometimes happens when you try to Insert/Update
an entity while the foreign key
that you are trying to Insert/Update
actually does not exist. So, be sure that the foreign key
exists and try again.
Here is the general solution if you really only want the first key's value
Object firstKey = myHashMap.keySet().toArray()[0];
Object valueForFirstKey = myHashMap.get(firstKey);
As @Ninefingers mentioned, pthreads are unix-only. Posix only, really.
That said, Microsoft does have a library that duplicates pthreads:
Maybe something changed but this gave back a list of ndarrays which did what I needed.
list(df.values)
I like Raynos' solution as well, but I prefer a different flow control library.

Depending on whether you need the results in each subsequent function, I'd either use series, parallel, or waterfall.
Series when they have to be serially executed, but you don't necessarily need the results in each subsequent function call.
Parallel if they can be executed in parallel, you don't need the results from each during each parallel function, and you need a callback when all have completed.
Waterfall if you want to morph the results in each function and pass to the next
endpoints =
[{ host: 'www.example.com', path: '/api_1.php' },
{ host: 'www.example.com', path: '/api_2.php' },
{ host: 'www.example.com', path: '/api_3.php' }];
async.mapSeries(endpoints, http.get, function(results){
// Array of results
});
Your selector is missing a .
and though you say you want to change the border-color
- you're adding and removing a class that sets the background-color
Simple solution:
<iframe onload="this.style.height=this.contentWindow.document.body.scrollHeight + 'px';" ...></iframe>
This works when the iframe and parent window are in the same domain. It does not work when the two are in different domains.
For the record, rjson and RJSONIO do change the file type, but they don't really parse per se. For instance, I receive ugly MongoDB data in JSON format, convert it with rjson or RJSONIO, then use unlist and tons of manual correction to actually parse it into a usable matrix.
Some timing tests for cpython 3 shows that a simple for loop is the fastest way, and it's quite readable. Adding in a function doesn't cause much overhead either:
timeit results (10k iterations):
all(x.pop(v) for v in r) # 0.85
all(map(x.pop, r)) # 0.60
list(map(x.pop, r)) # 0.70
all(map(x.__delitem__, r)) # 0.44
del_all(x, r) # 0.40
<inline for loop>(x, r) # 0.35
def del_all(mapping, to_remove):
"""Remove list of elements from mapping."""
for key in to_remove:
del mapping[key]
For small iterations, doing that 'inline' was a bit faster, because of the overhead of the function call. But del_all
is lint-safe, reusable, and faster than all the python comprehension and mapping constructs.
If you need to do this a lot, you can precalculate all possible strings for number of seconds in a day:
try:
from itertools import product
except ImportError:
def product(*seqs):
if len(seqs) == 1:
for p in seqs[0]:
yield p,
else:
for s in seqs[0]:
for p in product(*seqs[1:]):
yield (s,) + p
hhmmss = []
for (h, m, s) in product(range(24), range(60), range(60)):
hhmmss.append("%02d:%02d:%02d" % (h, m, s))
Now conversion of seconds to format string is a fast indexed lookup:
print hhmmss[12345]
prints
'03:25:45'
EDIT:
Updated to 2020, removing Py2 compatibility ugliness, and f-strings!
import sys
from itertools import product
hhmmss = [f"{h:02d}:{m:02d}:{s:02d}"
for h, m, s in product(range(24), range(60), range(60))]
# we can still just index into the list, but define as a function
# for common API with code below
seconds_to_str = hhmmss.__getitem__
print(seconds_to_str(12345))
How much memory does this take? sys.getsizeof
of a list won't do, since it will just give us the size of the list and its str refs, but not include the memory of the strs themselves:
# how big is a list of 24*60*60 8-character strs?
list_size = sys.getsizeof(hhmmss) + sum(sys.getsizeof(s) for s in hhmmss)
print("{:,}".format(list_size))
prints:
5,657,616
What if we just had one big str? Every value is exactly 8 characters long, so we can slice into this str and get the correct str for second X of the day:
hhmmss_str = ''.join([f"{h:02d}:{m:02d}:{s:02d}"
for h, m, s in product(range(24),
range(60),
range(60))])
def seconds_to_str(n):
loc = n * 8
return hhmmss_str[loc: loc+8]
print(seconds_to_str(12345))
Did that save any space?
# how big is a str of 24*60*60*8 characters?
str_size = sys.getsizeof(hhmmss_str)
print("{:,}".format(str_size))
prints:
691,249
Reduced to about this much:
print(str_size / list_size)
prints:
0.12218026108523448
On the performance side, this looks like a classic memory vs. CPU tradeoff:
import timeit
print("\nindex into pre-calculated list")
print(timeit.timeit("hhmmss[6]", '''from itertools import product; hhmmss = [f"{h:02d}:{m:02d}:{s:02d}"
for h, m, s in product(range(24),
range(60),
range(60))]'''))
print("\nget slice from pre-calculated str")
print(timeit.timeit("hhmmss_str[6*8:7*8]", '''from itertools import product; hhmmss_str=''.join([f"{h:02d}:{m:02d}:{s:02d}"
for h, m, s in product(range(24),
range(60),
range(60))])'''))
print("\nuse datetime.timedelta from stdlib")
print(timeit.timeit("timedelta(seconds=6)", "from datetime import timedelta"))
print("\ninline compute of h, m, s using divmod")
print(timeit.timeit("n=6;m,s=divmod(n,60);h,m=divmod(m,60);f'{h:02d}:{m:02d}:{s:02d}'"))
On my machine I get:
index into pre-calculated list
0.0434853
get slice from pre-calculated str
0.1085147
use datetime.timedelta from stdlib
0.7625738
inline compute of h, m, s using divmod
2.0477764
Try this
keys = [next(iter(x.keys())) for x in test]
print(list(keys))
The result looks like this. ['foo', 'hello']
You can find more possible solutions here.
Here author performed tests showed that integer unix timestamp is better than DateTime. Note, he used MySql. But I feel no matter what DB engine you use comparing integers are slightly faster than comparing dates so int index is better than DateTime index. Take T1 - time of comparing 2 dates, T2 - time of comparing 2 integers. Search on indexed field takes approximately O(log(rows)) time because index based on some balanced tree - it may be different for different DB engines but anyway Log(rows) is common estimation. (if you not use bitmask or r-tree based index). So difference is (T2-T1)*Log(rows) - may play role if you perform your query oftenly.
You should always refrain from increasing the timeouts, I doubt your backend server response time is the issue here in any case.
I got around this issue by clearing the connection keep-alive flag and specifying http version as per the answer here: https://stackoverflow.com/a/36589120/479632
server {
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
# these two lines here
proxy_http_version 1.1;
proxy_set_header Connection "";
proxy_pass http://localhost:5000;
}
}
Unfortunately I can't explain why this works and didn't manage to decipher it from the docs mentioned in the answer linked either so if anyone has an explanation I'd be very interested to hear it.
You should give the container an id and use that in your custom css file (which should be linked after the bootstrap css):
#container {
box-shadow: values
}
The other answers are correct, but you can, of course, do something like:
>>> str1 = "mystring"
>>> list1 = list(str1)
>>> list1[5] = 'u'
>>> str1 = ''.join(list1)
>>> print(str1)
mystrung
>>> type(str1)
<type 'str'>
if you really want to.
Here's an example that puts the Now()
value in column A.
Sub move()
Dim i As Integer
Dim sh1 As Worksheet
Dim sh2 As Worksheet
Dim nextRow As Long
Dim copyRange As Range
Dim destRange As Range
Application.ScreenUpdating = False
Set sh1 = ActiveWorkbook.Worksheets("Sheet1")
Set sh2 = ActiveWorkbook.Worksheets("Sheet2")
Set copyRange = sh1.Range("A1:A5")
i = Application.WorksheetFunction.CountA(sh2.Range("B:B")) + 4
Set destRange = sh2.Range("B" & i)
destRange.Resize(1, copyRange.Rows.Count).Value = Application.Transpose(copyRange.Value)
destRange.Offset(0, -1).Value = Format(Now(), "MMM-DD-YYYY")
copyRange.Clear
Application.ScreenUpdating = True
End Sub
There are better ways of getting the last row in column B than using a While
loop, plenty of examples around here. Some are better than others but depend on what you're doing and what your worksheet structure looks like. I used one here which assumes that column B is ALL empty except the rows/records you're moving. If that's not the case, or if B1:B3
have some values in them, you'd need to modify or use another method. Or you could just use your loop, but I'd search for alternatives :)
Your memcpy
code is correct.
My guess is you are lacking an include of string.h. So the compiler assumes a wrong prototype of memcpy
and thus the warning.
Anyway, you should just assign the structs for the sake of simplicity (as Joachim Pileborg pointed out).
Quite often the issue is a non-breaking space - CHAR(160)
- especially from Web text sources -that CLEAN
can't remove, so I would go a step further than this and try a formula like this which replaces any non-breaking spaces with a standard one
=TRIM(CLEAN(SUBSTITUTE(A1,CHAR(160)," ")))
Ron de Bruin has an excellent post on tips for cleaning data here
You can also remove the CHAR(160)
directly without a workaround formula by
ALT
and type 0160
using the numeric keypadI Created this module to help make this process piece of cake
You can do things like:
$routeProvider
.state('secret',
{
...
permissions: {
only: ['admin', 'god']
}
});
Or also
$routeProvider
.state('userpanel',
{
...
permissions: {
except: ['not-logged-in']
}
});
It's brand new but worth checking out!
Method to check array for null or empty also is present on org.apache.commons.lang:
import org.apache.commons.lang.ArrayUtils;
ArrayUtils.isEmpty(array);

Use the above link
private void btnopen_Click(object sender, EventArgs e){
OpenFileDialog openFileDialog1 = new OpenFileDialog();
if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK){
axAcroPDF1.src = openFileDialog1.FileName;
}
}
Yes, you can!
$str = 'One';
$class = 'Class'.$str;
$object = new $class();
When using namespaces, supply the fully qualified name:
$class = '\Foo\Bar\MyClass';
$instance = new $class();
Other cool stuff you can do in php are:
Variable variables:
$personCount = 123;
$varname = 'personCount';
echo $$varname; // echo's 123
And variable functions & methods.
$func = 'my_function';
$func('param1'); // calls my_function('param1');
$method = 'doStuff';
$object = new MyClass();
$object->$method(); // calls the MyClass->doStuff() method.
There's also str_pad
<?php
$input = "Alien";
echo str_pad($input, 10); // produces "Alien "
echo str_pad($input, 10, "-=", STR_PAD_LEFT); // produces "-=-=-Alien"
echo str_pad($input, 10, "_", STR_PAD_BOTH); // produces "__Alien___"
echo str_pad($input, 6 , "___"); // produces "Alien_"
?>

Thanks to CSS3 there is a solution !
The solution is to put the image as background-image
and then set the background-size
to contain
.
HTML
<div class='bounding-box'>
</div>
CSS
.bounding-box {
background-image: url(...);
background-repeat: no-repeat;
background-size: contain;
}
Test it here: http://www.w3schools.com/cssref/playit.asp?filename=playcss_background-size&preval=contain
Full compatibility with latest browsers: http://caniuse.com/background-img-opts
To align the div in the center, you can use this variation:
.bounding-box {
background-image: url(...);
background-size: contain;
position: absolute;
background-position: center;
background-repeat: no-repeat;
height: 100%;
width: 100%;
}
You can prefix the function declaration with extern “C” keyword, e.g.
extern “C” int Mycppfunction()
{
// Code goes here
return 0;
}
For more examples you can search more on Google about “extern” keyword. You need to do few more things, but it's not difficult you'll get lots of examples from Google.
Surrounding the path and the argument with spaces inside quotes as in your example should do. The command may need to handle the quotes when the parameters are passed to it, but it usually is not a big deal.
Take note of what is printed for x
. You are trying to convert an array (basically just a list) into an int. length-1
would be an array of a single number, which I assume numpy just treats as a float. You could do this, but it's not a purely-numpy solution.
EDIT: I was involved in a post a couple of weeks back where numpy was slower an operation than I had expected and I realised I had fallen into a default mindset that numpy was always the way to go for speed. Since my answer was not as clean as ayhan's, I thought I'd use this space to show that this is another such instance to illustrate that vectorize
is around 10% slower than building a list in Python. I don't know enough about numpy to explain why this is the case but perhaps someone else does?
import numpy as np
import matplotlib.pyplot as plt
import datetime
time_start = datetime.datetime.now()
# My original answer
def f(x):
rebuilt_to_plot = []
for num in x:
rebuilt_to_plot.append(np.int(num))
return rebuilt_to_plot
for t in range(10000):
x = np.arange(1, 15.1, 0.1)
plt.plot(x, f(x))
time_end = datetime.datetime.now()
# Answer by ayhan
def f_1(x):
return np.int(x)
for t in range(10000):
f2 = np.vectorize(f_1)
x = np.arange(1, 15.1, 0.1)
plt.plot(x, f2(x))
time_end_2 = datetime.datetime.now()
print time_end - time_start
print time_end_2 - time_end
The search criteria is one of these:
input[type=checkbox].MyClass:not(:checked)
input[type=checkbox].MyClass:checked
You probably want to connect to the change event.
In jQuery there is $.isPlainObject()
method for that:
Description: Check to see if an object is a plain object (created using "{}" or "new Object").
A new list is created but the items in it are references to the orginal items (just like in the original list). Changes to the list itself are independent, but to the items will find the change in both lists.
I guess you need something like this:
const MySelect = props => (
<Select
{...props}
value={props.options.filter(option => option.label === 'Some label')}
onChange={value => props.input.onChange(value)}
onBlur={() => props.input.onBlur(props.input.value)}
options={props.options}
placeholder={props.placeholder}
/>
);
I had missed another tiny detail: I forgot the brackets "(100)" behind NVARCHAR.
I'd like to expand a little bit on Pavel Minaev's answer, which you should read before reading my answer. Both solutions presented by Pavel won't compile if the member to be compared (such as id
in the question's code) is private. In this case, VS2013 throws the following error for me:
error C2248: 'Class1::id' : cannot access private member declared in class 'Class1'
As mentioned by SkyWalker in the comments on Pavel's answer, using a friend
declaration helps. If you wonder about the correct syntax, here it is:
class Class1
{
public:
Class1(int id) : id(id) {}
private:
int id;
friend struct Class1Compare; // Use this for Pavel's first solution.
friend struct std::less<Class1>; // Use this for Pavel's second solution.
};
However, if you have an access function for your private member, for example getId()
for id
, as follows:
class Class1
{
public:
Class1(int id) : id(id) {}
int getId() const { return id; }
private:
int id;
};
then you can use it instead of a friend
declaration (i.e. you compare lhs.getId() < rhs.getId()
).
Since C++11, you can also use a lambda expression for Pavel's first solution instead of defining a comparator function object class.
Putting everything together, the code could be writtem as follows:
auto comp = [](const Class1& lhs, const Class1& rhs){ return lhs.getId() < rhs.getId(); };
std::map<Class1, int, decltype(comp)> c2int(comp);
