Here is another alternative that I insert at top of the Python files in tests
folder:
# Path hack.
import sys, os
sys.path.insert(0, os.path.abspath('..'))
Use Notepad ++ and use the option to Convert the file to UNIX format. That should solve this problem.
What works for me is removing the dynamically-built .suo file (Solution User Options), in the .vs (hidden) directory located at he same path as the solution file.
I have this problem sometimes coming back, and it's on different project's/solutions, but never VS wide. New Projects always work fine.
Running VS2015 Professional Update -2-
partition() may be better then split() for this purpose as it has the better predicable results for situations you have no delimiter or more delimiters.
Already some great answers to this question, however here is a nice snippet that I use regularly to drop rows if they have non-numeric values on some columns:
# Eliminate invalid data from dataframe (see Example below for more context)
num_df = (df.drop(data_columns, axis=1)
.join(df[data_columns].apply(pd.to_numeric, errors='coerce')))
num_df = num_df[num_df[data_columns].notnull().all(axis=1)]
The way this works is we first drop
all the data_columns
from the df
, and then use a join
to put them back in after passing them through pd.to_numeric
(with option 'coerce'
, such that all non-numeric entries are converted to NaN
). The result is saved to num_df
.
On the second line we use a filter that keeps only rows where all values are not null.
Note that pd.to_numeric
is coercing to NaN
everything that cannot be converted to a numeric value, so strings that represent numeric values will not be removed. For example '1.25'
will be recognized as the numeric value 1.25
.
Disclaimer: pd.to_numeric
was introduced in pandas version 0.17.0
Example:
In [1]: import pandas as pd
In [2]: df = pd.DataFrame({"item": ["a", "b", "c", "d", "e"],
...: "a": [1,2,3,"bad",5],
...: "b":[0.1,0.2,0.3,0.4,0.5]})
In [3]: df
Out[3]:
a b item
0 1 0.1 a
1 2 0.2 b
2 3 0.3 c
3 bad 0.4 d
4 5 0.5 e
In [4]: data_columns = ['a', 'b']
In [5]: num_df = (df
...: .drop(data_columns, axis=1)
...: .join(df[data_columns].apply(pd.to_numeric, errors='coerce')))
In [6]: num_df
Out[6]:
item a b
0 a 1 0.1
1 b 2 0.2
2 c 3 0.3
3 d NaN 0.4
4 e 5 0.5
In [7]: num_df[num_df[data_columns].notnull().all(axis=1)]
Out[7]:
item a b
0 a 1 0.1
1 b 2 0.2
2 c 3 0.3
4 e 5 0.5
I wasn't able to find any that handled my particular situation, which was removing urls in the middle of tweets that also have whitespaces in the middle of urls so I made my own:
(https?:\/\/)(\s)*(www\.)?(\s)*((\w|\s)+\.)*([\w\-\s]+\/)*([\w\-]+)((\?)?[\w\s]*=\s*[\w\%&]*)*
here's an explanation:
(https?:\/\/)
matches http:// or https://
(\s)*
optional whitespaces
(www\.)?
optionally matches www.
(\s)*
optionally matches whitespaces
((\w|\s)+\.)*
matches 0 or more of one or more word characters followed by a period
([\w\-\s]+\/)*
matches 0 or more of one or more words(or a dash or a space) followed by '\'
([\w\-]+)
any remaining path at the end of the url followed by an optional ending
((\?)?[\w\s]*=\s*[\w\%&]*)*
matches ending query params (even with white spaces,etc)
test this out here:https://regex101.com/r/NmVGOo/8
First of all, slower with respect to what? C? Python? Let's get some numbers at the Computer Language Benchmarks Game:
Why is Ruby considered slow?
Depends on whom you ask. You could be told that:
But, then again, slow with respect to what? Ruby 1.9 is about as fast as Python and PHP (within a 3x performance factor) when compared to C (which can be up to 300x faster), so the above (with the exception of threading considerations, should your application heavily depend on this aspect) are largely academic.
What are your options as a Ruby programmer if you want to deal with this "slowness"?
Write for scalability and throw more hardware at it (e.g. memory)
Which version of Ruby would best suit an application like Stack Overflow where speed is critical and traffic is intense?
Well, REE (combined with Passenger) would be a very good candidate.
With the introduction of C# 6 (in VS 2015), you can now have get
-only automatic properties, in which the implicit backing field is readonly
(i.e. values can be assigned in the constructor but not elsewhere):
public string Name { get; }
public Customer(string name) // Constructor
{
Name = name;
}
private void SomeFunction()
{
Name = "Something Else"; // Compile-time error
}
And you can now also initialise properties (with or without a setter) inline:
public string Name { get; } = "Boris";
Referring back to the question, this gives you the advantages of option 2 (public member is a property, not a field) with the brevity of option 1.
Unfortunately, it doesn't provide a guarantee of immutability at the level of the public interface (as in @CodesInChaos's point about self-documentation), because to a consumer of the class, having no setter is indistinguishable from having a private setter.

Use a smarty template for your stuff then just set the POST array as a smarty array and open the template. In the template just echo out the array so if it passes:
if(correct){
header("Location: passed.php");
} else {
$smarty->assign("variables", $_POST);
$smarty->display("register_error.php");
exit;
}
I have not tried this yet but I am going to try it as a solution and will let you know what I find. But of course this method assumes that you are using smarty.
If not you can just recreate your form there on the error page and echo info into the form or you could send back non important data in a get from and get it
ex.
register.php?name=mr_jones&address==......
echo $_GET[name];
public static int GCD(int x, int y) {
int r;
while (y!=0) {
r = x%y;
x = y;
y = r;
}
return x;
}
In case you're still wondering how to do it, then add: &feature=youtu.be&hd=1 Actually now I checked, this works only when you're sending the URL to someone else, not on embed.
You can use jquery for this:
$('body').bind('copy paste',function(e) {
e.preventDefault(); return false;
});

I'm not aware of anything like a single table that lets you compare all of them in at one glance (I'm not sure such a table would even be feasible).
Of course the ISO standard document enumerates the complexity requirements in detail, sometimes in various rather readable tables, other times in less readable bullet points for each specific method.
Also the STL library reference at http://www.cplusplus.com/reference/stl/ provides the complexity requirements where appropriate.
I found a tricky way, just for brainstorm, see the code:
df['a'] = df['A'] # create a shadow column for MultiIndexing
df.sort_values('A', inplace=True)
df.set_index(["A","a"], inplace=True)
print(df)
the output:
B
A a
one one 0
one 1
one 5
three three 3
three 4
two two 2
The pros is so easy to print, as it returns a dataframe, instead of Groupby Object. And the output looks nice. While the con is that it create a series of redundant data.
It seems to me there is value in considering some rewrites to your SQL code before attempting to translate it.
Personally, I'd write such a query as a union (although I'd avoid nulls entirely!):
SELECT f.value
FROM period as p JOIN facts AS f ON p.id = f.periodid
WHERE p.companyid = 100
AND f.otherid = 17
UNION
SELECT NULL AS value
FROM period as p
WHERE p.companyid = 100
AND NOT EXISTS (
SELECT *
FROM facts AS f
WHERE p.id = f.periodid
AND f.otherid = 17
);
So I guess I agree with the spirit of @MAbraham1's answer (though their code seems to be unrelated to the question).
However, it seems the query is expressly designed to produce a single column result comprising duplicate rows -- indeed duplicate nulls! It's hard not to come to the conclusion that this approach is flawed.
Override method authenticationManagerBean
in WebSecurityConfigurerAdapter
to expose the AuthenticationManager built using configure(AuthenticationManagerBuilder)
as a Spring bean:
For example:
@Bean(name = BeanIds.AUTHENTICATION_MANAGER)
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
The ALL_DIRECTORIES

Link with -static. When you link with -static the linker embeds the library inside the executable, so the executable will be bigger, but it can be executed on a system with an older version of glibc because the program will use it's own library instead of that of the system.

If you want to cancel pending requests on stateChangeStart with ui-router, you can use something like this:
// in service
var deferred = $q.defer();
var scope = this;
$http.get(URL, {timeout : deferred.promise, cancel : deferred}).success(function(data){
//do something
deferred.resolve(dataUsage);
}).error(function(){
deferred.reject();
});
return deferred.promise;
// in UIrouter config
$rootScope.$on('$stateChangeStart', function (event, toState, toParams, fromState, fromParams) {
//To cancel pending request when change state
angular.forEach($http.pendingRequests, function(request) {
if (request.cancel && request.timeout) {
request.cancel.resolve();
}
});
});
In hibernate you can use this code to easily map your native query.
private List < Map < String, Object >> getNativeQueryResultInMap() {
String mapQueryStr = "SELECT * FROM AB_SERVICE three ";
Query query = em.createNativeQuery(mapQueryStr);
NativeQueryImpl nativeQuery = (NativeQueryImpl) query;
nativeQuery.setResultTransformer(AliasToEntityMapResultTransformer.INSTANCE);
List < Map < String, Object >> result = query.getResultList();
for (Map map: result) {
System.out.println("after request ::: " + map);
}
return result;}
Since Python lists are zero-based, we can use the zip built-in function as follows:
>>> [i for i,j in zip(range(len(haystack)), haystack) if j == 'needle' ]
where "haystack" is the list in question and "needle" is the item to look for.
(Note: Here we are iterating using i to get the indexes, but if we need rather to focus on the items we can switch to j.)
Also, in addition to torek's answer: one thing that stands out is that you're using a lazily-evaluated macro assignment.
If you're on GNU Make, use the :=
assignment instead of =
. This assignment causes the right hand side to be expanded immediately, and stored in the left hand variable.
FILES := $(shell ...) # expand now; FILES is now the result of $(shell ...)
FILES = $(shell ...) # expand later: FILES holds the syntax $(shell ...)
If you use the =
assignment, it means that every single occurrence of $(FILES)
will be expanding the $(shell ...)
syntax and thus invoking the shell command. This will make your make job run slower, or even have some surprising consequences.
The simplest way imho:
let hours = time / 3600
let minutes = (time / 60) % 60
let seconds = time % 60
return String(format: "%0.2d:%0.2d:%0.2d", hours, minutes, seconds)
A Popen
object has a .wait()
method exactly defined for this: to wait for the completion of a given subprocess (and, besides, for retuning its exit status).
If you use this method, you'll prevent that the process zombies are lying around for too long.
(Alternatively, you can use subprocess.call()
or subprocess.check_call()
for calling and waiting. If you don't need IO with the process, that might be enough. But probably this is not an option, because your if the two subprocesses seem to be supposed to run in parallel, which they won't with (check_
)call()
.)
If you have several subprocesses to wait for, you can do
exit_codes = [p.wait() for p in p1, p2]
which returns as soon as all subprocesses have finished. You then have a list of return codes which you maybe can evaluate.
Call

You can do this with iOS 7's text attachments, which are part of TextKit. Some sample code:
NSTextAttachment *attachment = [[NSTextAttachment alloc] init];
attachment.image = [UIImage imageNamed:@"MyIcon.png"];
NSAttributedString *attachmentString = [NSAttributedString attributedStringWithAttachment:attachment];
NSMutableAttributedString *myString= [[NSMutableAttributedString alloc] initWithString:@"My label text"];
[myString appendAttributedString:attachmentString];
myLabel.attributedText = myString;
cd /d c:\
git clone C:\folder1 folder2
From the documentation for git clone
:
For local repositories, also supported by git natively, the following syntaxes may be used:
/path/to/repo.git/ file:///path/to/repo.git/
These two syntaxes are mostly equivalent, except the former implies --local option.
*IntelliJ 13 * (its paid for) We found you have to have the cursor in the actual class before ctrl+Shift+T worked.
Which seems a bit restrictive if its the only way to generate a test class. Although in retrospect it would force developers to create a test class when they write a functional class.
Using Java :
String newString = "";
String a = "My name is X Y Z";
int n = a.length();
int k = n-1;
int j=0;
for (int i=n-1; i>=0; i--)
{
if (a.charAt(i) == ' ' || i==0)
{
j= (i!=0)?i+1:i;
while(j<=k)
{
newString = newString + a.charAt(j);
j=j+1;
}
newString = newString + " ";
k=i-1;
}
}
System.out.println(newString);
Complexity is O(n) [traversing entire array] + O(n) [traversing each word again] = O(n)
if let navigationController = self.navigationController, navigationController.isBeingPresented {

You can do a printf to anything that is an OutputStream with a PrintStream. Somehow like this, printing into a string stream:
PrintStream ps = new PrintStream(baos);
ps.printf("there is a %s from %d %s", "hello", 3, "friends");
System.out.println(baos.toString());
baos.reset(); //need reset to write new string
ps.printf("there is a %s from %d %s", "flip", 5, "haters");
System.out.println(baos.toString());
baos.reset();
The string stream can be created like this ByteArrayOutputStream:
ByteArrayOutputStream baos = new ByteArrayOutputStream();
pd.datetime.now().strftime("%d/%m/%Y")
this will give output as '11/02/2019'
you can use add time if you want
pd.datetime.now().strftime("%d/%m/%Y %I:%M:%S")
this will give output as '11/02/2019 11:08:26'
Use subscripting to access the value for a dictionary key. This will return an Optional:
let apple: String? = companies["AAPL"]
or
if let apple = companies["AAPL"] {
// ...
}
You can also enumerate over all of the keys and values:
var companies = ["AAPL" : "Apple Inc", "GOOG" : "Google Inc", "AMZN" : "Amazon.com, Inc", "FB" : "Facebook Inc"]
for (key, value) in companies {
print("\(key) -> \(value)")
}
Or enumerate over all of the values:
for value in Array(companies.values) {
print("\(value)")
}
function addclassName(){
setTimeout(function(){
var c = document.querySelectorAll(".modal-backdrop");
for (var i = 0; i < c.length; i++) {
c[i].style.zIndex = 1040 + i * 20 ;
}
var d = document.querySelectorAll(".modal.fade");
for(var i = 0; i<d.length; i++){
d[i].style.zIndex = 1050 + i * 20;
}
}, 10);
}
input[readonly], input:read-only {
/* styling info here */
}

Put that file in assets.
For project created in Android Studio project you need to create assets folder under the main folder.
Read that file as:
public String loadJSONFromAsset(Context context) {
String json = null;
try {
InputStream is = context.getAssets().open("file_name.json");
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
json = new String(buffer, "UTF-8");
} catch (IOException ex) {
ex.printStackTrace();
return null;
}
return json;
}
and then you can simply read this string
return by this function as
JSONObject obj = new JSONObject(json_return_by_the_function);
For further details regarding JSON see http://www.vogella.com/articles/AndroidJSON/article.html
Hope you will get what you want.
Take the following folder structure
notice:
Now in the index.html.en
file you'll want to put the following markup
<p>
<span>src="check_mark.png"</span>
<img src="check_mark.png" />
<span>I'm purple because I'm referenced from this current directory</span>
</p>
<p>
<span>src="/check_mark.png"</span>
<img src="/check_mark.png" />
<span>I'm green because I'm referenced from the ROOT directory</span>
</p>
<p>
<span>src="subfolder/check_mark.png"</span>
<img src="subfolder/check_mark.png" />
<span>I'm yellow because I'm referenced from the child of this current directory</span>
</p>
<p>
<span>src="/subfolder/check_mark.png"</span>
<img src="/subfolder/check_mark.png" />
<span>I'm orange because I'm referenced from the child of the ROOT directory</span>
</p>
<p>
<span>src="../subfolder/check_mark.png"</span>
<img src="../subfolder/check_mark.png" />
<span>I'm purple because I'm referenced from the parent of this current directory</span>
</p>
<p>
<span>src="subfolder/subfolder/check_mark.png"</span>
<img src="subfolder/subfolder/check_mark.png" />
<span>I'm [broken] because there is no subfolder two children down from this current directory</span>
</p>
<p>
<span>src="/subfolder/subfolder/check_mark.png"</span>
<img src="/subfolder/subfolder/check_mark.png" />
<span>I'm purple because I'm referenced two children down from the ROOT directory</span>
</p>
Now if you load up the index.html.en
file located in the second subfolder
http://example.com/subfolder/subfolder/
This will be your output
It just means it expects that as a key in your header data
import requests
endpoint = ".../api/ip"

headers = {"Authorization": "Bearer MYREALLYLONGTOKENIGOT"}
print(requests.post(endpoint, data=data, headers=headers).json())
It has been asked in the past, apparently it costs a lot to mobile browsers, so it's been disabled.
Check this comment by @PaulIrish:
Fixed-backgrounds have huge repaint cost and decimate scrolling performance, which is, I believe, why it was disabled.
you can see workarounds to this in this posts:
You can try console.log("%cI am red %cI am green", "color: red", "color: green");
http://www.example.com/some/path/to/resource?param1=value1
The part before the question mark must use % encoding (so %20
for space), after the question mark you can use either %20
or +
for a space. If you need an actual +
after the question mark use %2B
.
For anyone with the same issue as I had, I was calling a public method method1
from within another class.
method1
then called another public method method2
within the same class.
method2
was annotated with @Transactional
, but method1
was not.
All that method1
did was transform some arguments and directly call method2
, so no DB operations here.
The issue got solved for me once I moved the @Transactional
annotation to method1
.
Not sure the reason for this, but this did it for me.
An alternative that works for me is to simply convert to a CSV.
I think this is what you're looking for.
List<String> columnData = new List<String>();
using(SqlConnection connection = new SqlConnection("conn_string"))
{
connection.Open();
string query = "SELECT Column1 FROM Table1";
using(SqlCommand command = new SqlCommand(query, connection))
{
using (SqlDataReader reader = command.ExecuteReader())
{
while (reader.Read())
{
columnData.Add(reader.GetString(0));
}
}
}
}
Not tested, but this should work fine.
As in many other programming and scripting languages you can do so by adding !
in front of the condition
if (![string]::IsNullOrEmpty($version))
{
$request += "/" + $version
}
As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().
Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static
for the example. Once it's done, add this line in your server code:
app.use("/static", express.static('./static/'));
This will effectively serve every file in your "static" folder via the /static route.
Querying your index.js file in the client thus becomes:
<script src="static/index.js"></script>
MDN suggests that there's a much cleaner way of doing this in modern browsers:
// Assuming we're listening for e.g. a 'change' event on `element`
// Create a new 'change' event
var event = new Event('change');
// Dispatch it.
element.dispatchEvent(event);
I made a **
automatic-network-drive connector

Suddenly there was a networkdrive called "Data for Analysation", and yeah with the double quotes it works proper!
looks a little bit different but works:

Thx for the Hint :)
if your text doesn't spill over two rows then you can do line-height: ;
in your CSS, the more line-height you give, the lower on the container it will hold.
Also, you can use or create and share Visual Studio color schemes: https://studiostyl.es/
With the code in the question, you're only dealing interacting with the first of the four entries returned by that selector.
Code below as a fiddle: https://jsfiddle.net/c4nhpqgb/
I want to be overly clear that you have four items that matched that selector, so you need to deal with each explicitly. Using eq()
is a little more explicit making this point than the answers using map
, though map
or each
is what you'd probably use "in real life" (jquery docs for eq
here).

<script>
// using the $ prefix to use the "jQuery wrapped var" convention
var i, $mvar = $('.mbox');
// convenience method to display unprocessed html on the same page
function logit( string )
{
var text = document.createTextNode( string );
$('#outige').append(text);
$('#outige').append("<br>");
}
logit($mvar.length);
for (i=0; i<$mvar.length; i++) {
logit($mvar.eq(i).html());
}

There is no fixed limit on how large a JSON data block is or any of the fields.
There are limits to how much JSON the JavaScript implementation of various browsers can handle (e.g. around 40MB in my experience). See this question for example.
is what you are looking for something like intellisense?
insevim seems to address the issue.

You can also run this script to find out the Apache process owner:
<?php echo exec('whoami'); ?>
And then change the owner of the destination directory to what you've got. Use the command:
chown user destination_dir
And then use the command
chmod 755 destination_dir
to change the destination directory permission.
I believe you can diff against files in your index and untracked files by simply supplying the path to both files.
git diff --no-index tracked_file untracked_file
def evenly(l, n):
len_ = len(l)
split_size = len_ // n
split_size = n if not split_size else split_size
offsets = [i for i in range(0, len_, split_size)]
return [l[offset:offset + split_size] for offset in offsets]
Example:
l = [a for a in range(97)]

[18, 19, 20, 21, 22, 23, 24, 25, 26],
[27, 28, 29, 30, 31, 32, 33, 34, 35],
[36, 37, 38, 39, 40, 41, 42, 43, 44],

I have come to point out the answer nobody seems to see here. You can fullfill all requests you have made with pure CSS and it's very simple. Just use Media Queries. Media queries can check the orientation of the user's screen, or viewport. Then you can style your images depending on the orientation.
Just set your default CSS on your images like so:
img {
width:auto;
height:auto;
max-width:100%;
max-height:100%;
}
Then use some media queries to check your orientation and that's it!
@media (orientation: landscape) { img { height:100%; } }
@media (orientation: portrait) { img { width:100%; } }
You will always get an image that scales to fit the screen, never loses aspect ratio, never scales larger than the screen, never clips or overflows.
To learn more about these media queries, you can read MDN's specs.
To center your image horizontally and vertically, just use the flex box model. Use a parent div
set to 100% width and height, like so:
div.parent {
display:flex;
position:fixed;
left:0px;
top:0px;
width:100%;
height:100%;
justify-content:center;
align-items:center;
}
With the parent div's display
set to flex
, the element is now ready to use the flex box model. The justify-content
property sets the horizontal alignment of the flex items. The align-items
property sets the vertical alignment of the flex items.
I too had wanted these exact requirements and had scoured the web for a pure CSS solution. Since none of the answers here fulfilled all of your requirements, either with workarounds or settling upon sacrificing a requirement or two, this solution really is the most straightforward for your goals; as it fulfills all of your requirements with pure CSS.
EDIT: The accepted answer will only appear to work if your images are large. Try using small images and you will see that they can never be larger than their original size.
Coming to the party very very late, but from my old memory of DOS batch files, you can keep adding a character to the string each loop then look for a string of that many of that character. for 250 iterations, you either have a very long "cycles" string, or you have one loop inside using one set of variables counting to 10, then another loop outside that uses another set of variable counting to 25.
Here is the basic loop to 30:
@echo off
rem put how many dots you want to loop
set cycles=..............................
set cntr=
:LOOP
set cntr=%cntr%.
echo around we go again
if "%cycles%"=="%cntr%" goto done
goto loop
:DONE
echo around we went
I use the code provided by @Colin MacKenzie - III. Thanks a lot!
For someone who are looking for a replacement of 'deprecated' managedQuery:
1st, assuming using v4 support lib:
import android.support.v4.app.LoaderManager;
import android.support.v4.content.CursorLoader;
import android.support.v4.content.Loader;
2nd:
your_(activity)_class implements LoaderManager.LoaderCallbacks<Cursor>
3rd,
// temporarily store the 'data.getData()' from onActivityResult
private Uri tmp_url;
4th, override callbacks:
@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
// create the loader here!
CursorLoader cursorLoader = new CursorLoader(this, tmp_url, null, null, null, null);
return cursorLoader;
}
@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
getContactInfo(cursor); // here it is!
}
@Override
public void onLoaderReset(Loader<Cursor> loader) {
}
5th:
public void initLoader(Uri data){
// will be used in onCreateLoader callback
this.tmp_url = data;
// 'this' is an Activity instance, implementing those callbacks
this.getSupportLoaderManager().initLoader(0, null, this);
}
6th, the code above, except that I change the signature param from Intent to Cursor:
protected void getContactInfo(Cursor cursor)
{
// Cursor cursor = managedQuery(intent.getData(), null, null, null, null);
while (cursor.moveToNext())
{
// same above ...
}
7th, call initLoader:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (PICK_CONTACT == requestCode) {
this.initLoader(data.getData(), this);
}
}
8th, don't forget this piece of code
Intent intentContact = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
this.act.startActivityForResult(intentContact, PICK_CONTACT);

The two syntaxes for stubbing are roughly equivalent. However, you can always use doReturn/when
for stubbing; but there are cases where you can't use when/thenReturn
. Stubbing void methods is one such. Others include use with Mockito spies, and stubbing the same method more than once.
One thing that when/thenReturn
gives you, that doReturn/when
doesn't, is type-checking of the value that you're returning, at compile time. However, I believe this is of almost no value - if you've got the type wrong, you'll find out as soon as you run your test.
I strongly recommend only using doReturn/when
. There is no point in learning two syntaxes when one will do.
You may wish to refer to my answer at Forming Mockito "grammars" - a more detailed answer to a very closely related question.
One additional suggestion to be explicit. It seems best to go from specific to general down the stack of errors to get the desired error to be caught, so the specific ones don't get masked by the general one.

Basically, you need to catch the OperationCanceledException
and check the state of the cancellation token that was passed to SendAsync
(or GetAsync
, or whatever HttpClient
method you're using):
IsCancellationRequested
is true), it means the request really was canceledOf course, this isn't very convenient... it would be better to receive a TimeoutException
in case of timeout. I propose a solution here based on a custom HTTP message handler: Better timeout handling with HttpClient
To make an element have a line break afterwards, assign it:
display:block;
Non-floated elements after a block level element will appear on the next line. Many elements, such as <p> and <div> are already block level elements so you can just use those.
But while this is good to know, this really depends more on the context of your content. In your example, you would not want to use CSS to force a line break. The <br /> is appropriate because semantically the p tag is the the most appropriate for the text you are displaying. More markup just to hang CSS off it is unnecessary. Technically it's not exactly a paragraph, but there is no <greeting> tag, so use what you have. Describing your content well with HTMl is way more important - after you have that then figure out how to make it look pretty.
Perl solution:
perl -ane '$maxc = $#F if $#F > $maxc; END{$maxc++; print "max columns: $maxc\nrows: $.\n"}' file
If your input file is comma-separated:
perl -F, -ane '$maxc = $#F if $#F > $maxc; END{$maxc++; print "max columns: $maxc\nrows: $.\n"}' file
output:
max columns: 5
rows: 2
-a
autosplits input line to @F
array
$#F
is the number of columns -1
-F,
field separator of , instead of whitespace
$.
is the line number (number of rows)
For installing multiple packages on the command line, just pass them as a space-delimited list, e.g.:
pip install wsgiref boto
For installing from a text file, then, from pip install --help
:
-r FILENAME, --requirement=FILENAME
Install all the packages listed in the given requirements file. This option can be used multiple times.
Take a look at the pip documentation regarding requirements files for their general layout and syntax - note that you can generate one based on current environment / site-packages with pip freeze
if you want a quick example - e.g. (based on having installed wsgiref
and boto
in a clean virtualenv):
$ pip freeze
boto==2.3.0
wsgiref==0.1.2
Yes, you can try,
php_value error_log "/var/log/php_log"
in .htaccess
or you can have users use ini_set()
in the beginning of their scripts if they want to have logging.
Another option would be to enable scripts to default to the php.ini
in the folder with the script, then go to the user/host's root folder, then to the server's root, or something similar. This would allow hosts to add their own php.ini
values and their own error_log
locations.
The most important things POSIX 7 defines
Greatly extends ANSI C with things like:
mkdir
, dirname
, symlink
, readlink
, link
(hardlinks), poll()
, stat
, sync
, nftw()
fork
, execl
, wait
, pipe
, semaphors sem_*
, shared memory (shm_*
), kill
, scheduling parameters (nice
, sched_*
), sleep
, mkfifo
, setpgid()
socket()
mmap
, mlock
, mprotect
, madvise
, brk()
reg*
)Those APIs also determine underlying system concepts on which they depend, e.g. fork
requires a concept of a process.
Many Linux system calls exist to implement a specific POSIX C API function and make Linux compliant, e.g. sys_write
, sys_read
, ... Many of those syscalls also have Linux-specific extensions however.
Major Linux desktop implementation: glibc, which in many cases just provides a shallow wrapper to system calls.
E.g.: cd
, ls
, echo
, ...
Many utilities are direct shell front ends for a corresponding C API function, e.g. mkdir
.
Major Linux desktop implementation: GNU Coreutils for the small ones, separate GNU projects for the big ones: sed
, grep
, awk
, ... Some CLI utilities are implemented by Bash as built-ins.
E.g., a=b; echo "$a"
Major Linux desktop implementation: GNU Bash.
E.g.: HOME
, PATH
.
PATH
search semantics are specified, including how slashes prevent PATH
search.
ANSI C says 0
or EXIT_SUCCESS
for success, EXIT_FAILURE
for failure, and leaves the rest implementation defined.
POSIX adds:
126
: command found but not executable.
127
: command not found.
> 128
: terminated by a signal.
But POSIX does not seem to specify the 128 + SIGNAL_ID
rule used by Bash: https://unix.stackexchange.com/questions/99112/default-exit-code-when-process-is-terminated
There are two types: BRE (Basic) and ERE (Extended). Basic is deprecated and only kept to not break APIs.
Those are implemented by C API functions, and used throughout CLI utilities, e.g. grep
accepts BREs by default, and EREs with -E
.
E.g.: echo 'a.1' | grep -E 'a.[[:digit:]]'
Major Linux implementation: glibc implements the functions under regex.h which programs like grep
can use as backend.
E.g.: /dev/null
, /tmp

Command line utility API conventions
Not mandatory, used by POSIX, but almost nowhere else, notably not in GNU. But true, it is too restrictive, e.g. single letter flags only (e.g. -a
), no double hyphen long versions (e.g. --all
).
A few widely used conventions:
-
means stdin where a file is expected--
terminates flags, e.g. ls -- -l
to list a directory named -l
See also: Are there standards for Linux command line switches and arguments?
"POSIX ACLs" (Access Control Lists), e.g. as used as backend for setfacl
.
This was withdrawn but it was implemented in several OSes, including in Linux with setxattr
.
Who conforms to POSIX?
Many systems follow POSIX closely, but few are actually certified by the Open Group which maintains the standard. Notable certified ones include:
Most Linux distros are very compliant, but not certified because they don't want to pay the compliance check. Inspur's K-UX and Huawei's EulerOS are two certified examples.
The official list of certified systems be found at: https://www.opengroup.org/openbrand/register/ and also at the wiki page.
Windows
Windows implemented POSIX on some of its professional distributions.
Since it was an optional feature, programmers could not rely on it for most end user applications.
Support was deprecated in Windows 8:
In 2016 a new official Linux-like API called "Windows Subsystem for Linux" was announced. It includes Linux system calls, ELF running, parts of the /proc
filesystem, Bash, GCC, (TODO likely glibc?), apt-get
and more: https://channel9.msdn.com/Events/Build/2016/P488 so I believe that it will allow Windows to run much, if not all, of POSIX. However, it is focused on developers / deployment instead of end users. In particular, there were no plans to allow access to the Windows GUI.
Historical overview of the official Microsoft POSIX compatibility: http://brianreiter.org/2010/08/24/the-sad-history-of-the-microsoft-posix-subsystem/
Cygwin is a well known GPL third-party project for that "provides substantial POSIX API functionality" for Windows, but requires that you "rebuild your application from source if you want it to run on Windows". MSYS2 is a related project that seems to add more functionality on top of Cygwin.

This article is rather long. If you want to know about both aggregates and PODs (Plain Old Data) take time and read it. If you are interested just in aggregates, read only the first part. If you are interested only in PODs then you must first read the definition, implications, and examples of aggregates and then you may jump to PODs but I would still recommend reading the first part in its entirety. The notion of aggregates is essential for defining PODs. If you find any errors (even minor, including grammar, stylistics, formatting, syntax, etc.) please leave a comment, I'll edit.
This answer applies to C++03. For other C++ standards see:
Formal definition from the C++ standard (C++03 8.5.1 §1):
An aggregate is an array or a class (clause 9) with no user-declared constructors (12.1), no private or protected non-static data members (clause 11), no base classes (clause 10), and no virtual functions (10.3).
So, OK, let's parse this definition. First of all, any array is an aggregate. A class can also be an aggregate if… wait! nothing is said about structs or unions, can't they be aggregates? Yes, they can. In C++, the term class
refers to all classes, structs, and unions. So, a class (or struct, or union) is an aggregate if and only if it satisfies the criteria from the above definitions. What do these criteria imply?
This does not mean an aggregate class cannot have constructors, in fact it can have a default constructor and/or a copy constructor as long as they are implicitly declared by the compiler, and not explicitly by the user
No private or protected non-static data members. You can have as many private and protected member functions (but not constructors) as well as as many private or protected static data members and member functions as you like and not violate the rules for aggregate classes
An aggregate class can have a user-declared/user-defined copy-assignment operator and/or destructor
An array is an aggregate even if it is an array of non-aggregate class type.
Now let's look at some examples:
class NotAggregate1
{
virtual void f() {} //remember? no virtual functions
};
class NotAggregate2
{
int x; //x is private by default and non-static
};
class NotAggregate3
{
public:
NotAggregate3(int) {} //oops, user-defined constructor
};
class Aggregate1
{
public:
NotAggregate1 member1; //ok, public member
Aggregate1& operator=(Aggregate1 const & rhs) {/* */} //ok, copy-assignment
private:
void f() {} // ok, just a private function
};
You get the idea. Now let's see how aggregates are special. They, unlike non-aggregate classes, can be initialized with curly braces {}
. This initialization syntax is commonly known for arrays, and we just learnt that these are aggregates. So, let's start with them.
Type array_name[n] = {a1, a2, …, am};
if(m == n)
the ith element of the array is initialized with ai
else if(m < n)
the first m elements of the array are initialized with a1, a2, …, am and the other n - m
elements are, if possible, value-initialized (see below for the explanation of the term)
else if(m > n)
the compiler will issue an error
else (this is the case when n isn't specified at all like int a[] = {1, 2, 3};
)
the size of the array (n) is assumed to be equal to m, so int a[] = {1, 2, 3};
is equivalent to int a[3] = {1, 2, 3};
When an object of scalar type (bool
, int
, char
, double
, pointers, etc.) is value-initialized it means it is initialized with 0
for that type (false
for bool
, 0.0
for double
, etc.). When an object of class type with a user-declared default constructor is value-initialized its default constructor is called. If the default constructor is implicitly defined then all nonstatic members are recursively value-initialized. This definition is imprecise and a bit incorrect but it should give you the basic idea. A reference cannot be value-initialized. Value-initialization for a non-aggregate class can fail if, for example, the class has no appropriate default constructor.
Examples of array initialization:
class A
{
public:
A(int) {} //no default constructor
};
class B
{
public:
B() {} //default constructor available
};
int main()
{
A a1[3] = {A(2), A(1), A(14)}; //OK n == m
A a2[3] = {A(2)}; //ERROR A has no default constructor. Unable to value-initialize a2[1] and a2[2]
B b1[3] = {B()}; //OK b1[1] and b1[2] are value initialized, in this case with the default-ctor
int Array1[1000] = {0}; //All elements are initialized with 0;
int Array2[1000] = {1}; //Attention: only the first element is 1, the rest are 0;
bool Array3[1000] = {}; //the braces can be empty too. All elements initialized with false
int Array4[1000]; //no initializer. This is different from an empty {} initializer in that
//the elements in this case are not value-initialized, but have indeterminate values
//(unless, of course, Array4 is a global array)
int array[2] = {1, 2, 3, 4}; //ERROR, too many initializers
}
Now let's see how aggregate classes can be initialized with braces. Pretty much the same way. Instead of the array elements we will initialize the non-static data members in the order of their appearance in the class definition (they are all public by definition). If there are fewer initializers than members, the rest are value-initialized. If it is impossible to value-initialize one of the members which were not explicitly initialized, we get a compile-time error. If there are more initializers than necessary, we get a compile-time error as well.
struct X
{
int i1;
int i2;
};
struct Y
{
char c;
X x;
int i[2];
float f;
protected:
static double d;
private:
void g(){}
};
Y y = {'a', {10, 20}, {20, 30}};
In the above example y.c
is initialized with 'a'
, y.x.i1
with 10
, y.x.i2
with 20
, y.i[0]
with 20
, y.i[1]
with 30
and y.f
is value-initialized, that is, initialized with 0.0
. The protected static member d
is not initialized at all, because it is static
.
Aggregate unions are different in that you may initialize only their first member with braces. I think that if you are advanced enough in C++ to even consider using unions (their use may be very dangerous and must be thought of carefully), you could look up the rules for unions in the standard yourself :).
Now that we know what's special about aggregates, let's try to understand the restrictions on classes; that is, why they are there. We should understand that memberwise initialization with braces implies that the class is nothing more than the sum of its members. If a user-defined constructor is present, it means that the user needs to do some extra work to initialize the members therefore brace initialization would be incorrect. If virtual functions are present, it means that the objects of this class have (on most implementations) a pointer to the so-called vtable of the class, which is set in the constructor, so brace-initialization would be insufficient. You could figure out the rest of the restrictions in a similar manner as an exercise :).
So enough about the aggregates. Now we can define a stricter set of types, to wit, PODs
Formal definition from the C++ standard (C++03 9 §4):
A POD-struct is an aggregate class that has no non-static data members of type non-POD-struct, non-POD-union (or array of such types) or reference, and has no user-defined copy assignment operator and no user-defined destructor. Similarly, a POD-union is an aggregate union that has no non-static data members of type non-POD-struct, non-POD-union (or array of such types) or reference, and has no user-defined copy assignment operator and no user-defined destructor. A POD class is a class that is either a POD-struct or a POD-union.
Wow, this one's tougher to parse, isn't it? :) Let's leave unions out (on the same grounds as above) and rephrase in a bit clearer way:
An aggregate class is called a POD if it has no user-defined copy-assignment operator and destructor and none of its nonstatic members is a non-POD class, array of non-POD, or a reference.
What does this definition imply? (Did I mention POD stands for Plain Old Data?)
Examples:
struct POD
{
int x;
char y;
void f() {} //no harm if there's a function
static std::vector<char> v; //static members do not matter
};
struct AggregateButNotPOD1
{
int x;
~AggregateButNotPOD1() {} //user-defined destructor
};
struct AggregateButNotPOD2
{
AggregateButNotPOD1 arrOfNonPod[3]; //array of non-POD class
};
POD-classes, POD-unions, scalar types, and arrays of such types are collectively called POD-types.
PODs are special in many ways. I'll provide just some examples.
POD-classes are the closest to C structs. Unlike them, PODs can have member functions and arbitrary static members, but neither of these two change the memory layout of the object. So if you want to write a more or less portable dynamic library that can be used from C and even .NET, you should try to make all your exported functions take and return only parameters of POD-types.
The lifetime of objects of non-POD class type begins when the constructor has finished and ends when the destructor has finished. For POD classes, the lifetime begins when storage for the object is occupied and finishes when that storage is released or reused.
For objects of POD types it is guaranteed by the standard that when you memcpy
the contents of your object into an array of char or unsigned char, and then memcpy
the contents back into your object, the object will hold its original value. Do note that there is no such guarantee for objects of non-POD types. Also, you can safely copy POD objects with memcpy
. The following example assumes T is a POD-type:
#define N sizeof(T)
char buf[N];
T obj; // obj initialized to its original value
memcpy(buf, &obj, N); // between these two calls to memcpy,
// obj might be modified
memcpy(&obj, buf, N); // at this point, each subobject of obj of scalar type
// holds its original value
goto statement. As you may know, it is illegal (the compiler should issue an error) to make a jump via goto from a point where some variable was not yet in scope to a point where it is already in scope. This restriction applies only if the variable is of non-POD type. In the following example f()
is ill-formed whereas g()
is well-formed. Note that Microsoft's compiler is too liberal with this rule—it just issues a warning in both cases.
int f()
{
struct NonPOD {NonPOD() {}};
goto label;
NonPOD x;
label:
return 0;
}
int g()
{
struct POD {int i; char c;};
goto label;
POD x;
label:
return 0;
}
It is guaranteed that there will be no padding in the beginning of a POD object. In other words, if a POD-class A's first member is of type T, you can safely reinterpret_cast
from A*
to T*
and get the pointer to the first member and vice versa.
The list goes on and on…
It is important to understand what exactly a POD is because many language features, as you see, behave differently for them.
If you need to get the count of the entire result set you can take following approach:
SELECT SQL_CALC_FOUND_ROWS * FROM table_name LIMIT 5;
SELECT FOUND_ROWS();
This isn't normally faster than using COUNT
albeit one might think the opposite is the case because it's doing the calculation internally and doesn't send the data back to the user thus the performance improvement is suspected.
Doing these two queries is good for pagination for getting totals but not particularly for using WHERE
clauses.
You can use http_response_code()
to set HTTP response code.
If you pass no parameters then http_response_code will get the current status code. If you pass a parameter it will set the response code.
http_response_code(201); // Set response status code to 201
For Laravel(Reference from: https://stackoverflow.com/a/14717895/2025923):
return Response::json([
'hello' => $value
], 201); // Status code here
a = np.empty(0)
for x in y:
a = np.append(a, x)
This ridiculous error message merely means there's a binding to an array that doesn't exist.
<option
*ngFor="let option of setting.options"
[value]="option"
>{{ option }}
</option>
In the example above the value of setting.options is undefined. To fix, press F12 and open developer window. When the the get request returns the data look for the values to contain data.
If data exists, then make sure the binding name is correct
//was the property name correct?
setting.properNamedOptions
If the data exists, is it an Array?
If the data doesn't exist then fix it on the backend.
DISTINCT
is always a right choice to get unique values. Also you can do it alternatively without using it. That's GROUP BY
. Which has simply add at the end of the query and followed by the column name.

No, you'll have to specify the authentication method to use (typically "Basic") and the authentication realm. See http://en.wikipedia.org/wiki/Basic_access_authentication for an example request and response.
You might also want to read RFC 2617 - HTTP Authentication: Basic and Digest Access Authentication.
I think Link component does not have the props for it.
You can have alternative way by create a tag and use the makeHref method of Navigation mixin to create your url
<a target='_blank' href={this.makeHref(routeConsts.CHECK_DOMAIN, {},
{ realm: userStore.getState().realms[0].name })}>

You could do it if template is a react component.
Template.js
var React = require('react');
var Template = React.createClass({
render: function(){
return (<div>Mi HTML</div>);
}
});
module.exports = Template;
MainComponent.js
var React = require('react');
var ReactDOM = require('react-dom');
var injectTapEventPlugin = require("react-tap-event-plugin");
var Template = require('./Template');
//Needed for React Developer Tools
window.React = React;
//Needed for onTouchTap
//Can go away when react 1.0 release
//Check this repo:
//https://github.com/zilverline/react-tap-event-plugin
injectTapEventPlugin();
var MainComponent = React.createClass({
render: function() {
return(
<Template/>
);
}
});
// Render the main app react component into the app div.
// For more details see: https://facebook.github.io/react/docs/top-level-api.html#react.render
ReactDOM.render(
<MainComponent />,
document.getElementById('app')
);
And if you are using Material-UI, for compatibility use Material-UI Components, no normal inputs.
// works also after bind operation for WINDOWS
DWORD timeout = timeout_in_seconds * 1000;
setsockopt(socket, SOL_SOCKET, SO_RCVTIMEO, (const char*)&timeout, sizeof timeout);
You can simply use $_GET
especially if you know the othervar
's name.
If you want to be on the safe side, use if (isset ($_GET ['varname']))
to test for existence.
There is a very good fast food place analogy that best explains the event driven model of Node.js, see the full article, Node.js, Doctor’s Offices and Fast Food Restaurants – Understanding Event-driven Programming
Here is a summary:
If the fast food joint followed a traditional thread-based model, you'd order your food and wait in line until you received it. The person behind you wouldn't be able to order until your order was done. In an event-driven model, you order your food and then get out of line to wait. Everyone else is then free to order.
Node.js is event-driven, but most web servers are thread-based.York explains how Node.js works:
You use your web browser to make a request for "/about.html" on a Node.js web server.
The Node.js server accepts your request and calls a function to retrieve that file from disk.
While the Node.js server is waiting for the file to be retrieved, it services the next web request.
When the file is retrieved, there is a callback function that is inserted in the Node.js servers queue.
The Node.js server executes that function which in this case would render the "/about.html" page and send it back to your web browser."
"Requery" is indeed what you what you want to run, but you could do that in Form A's "On Got Focus" event. If you have code in your Form_Load, perhaps you can move it to Form_Got_Focus.
You need to do following:
1. Download PuTTYGen with Pageant.
2. Press "load" button and select your ".pem" file.
3. Press "save private key" button and save your ".ppk" file.
4. Open Pageant and press "add key" button. Just all. Keep running Pageant in background.
5. Now login through SSH or SFTP without selecting password field.
My solution. String must be changeable. The advantage above some of the other solutions that it moves the non-space part to the beginning so you can keep using the old pointer, in case you have to free() it later.
void trim(char * s) {
char * p = s;
int l = strlen(p);
while(isspace(p[l - 1])) p[--l] = 0;
while(* p && isspace(* p)) ++p, --l;
memmove(s, p, l + 1);
}
This version creates a copy of the string with strndup() instead of editing it in place. strndup() requires _GNU_SOURCE, so maybe you need to make your own strndup() with malloc() and strncpy().
char * trim(char * s) {
int l = strlen(s);
while(isspace(s[l - 1])) --l;
while(* s && isspace(* s)) ++s, --l;
return strndup(s, l);
}
I had been struggling with all of the above solutions and nothing helped here, because I used a String variable (plain text from a JTextPane) in combination with "text/html" formatting in my e-mail library.
So, the solution to this problem is to use "text/plain", instead of "text/html" and no need to replace return characters at all:
MimeBodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(message, "text/plain");
Set display.max_rows
:
pd.set_option('display.max_rows', 500)
For older versions of pandas (<=0.11.0) you need to change both display.height
and display.max_rows
.
pd.set_option('display.height', 500)
pd.set_option('display.max_rows', 500)
See also pd.describe_option('display')
.
You can set an option only temporarily for this one time like this:
from IPython.display import display
with pd.option_context('display.max_rows', 100, 'display.max_columns', 10):
display(df) #need display to show the dataframe when using with in jupyter
#some pandas stuff
You can also reset an option back to its default value like this:
pd.reset_option('display.max_rows')
And reset all of them back:
pd.reset_option('all')
See String Formatting Operations:
%d
is the format code for an integer. %f
is the format code for a float.
%s
prints the str()
of an object (What you see when you print(object)
).
%r
prints the repr()
of an object (What you see when you print(repr(object))
.
For a float %s, %r and %f all display the same value, but that isn't the case for all objects. The other fields of a format specifier work differently as well:
>>> print('%10.2s' % 1.123) # print as string, truncate to 2 characters in a 10-place field.
1.
>>> print('%10.2f' % 1.123) # print as float, round to 2 decimal places in a 10-place field.

Using Console.Write only works if the thread is the only thread writing to the Console, otherwise your output may be interspersed with other output that may or may not insert newlines, as well as other undesired characters. To ensure your array is printed intact, use Console.WriteLine to write one string. Most any array of objects can be printed horizontally (depending on the type's ToString() method) using the non-generic Join available before .NET 4.0:
int[] numbers = new int[100];
for(int i= 0; i < 100; i++)
{
numbers[i] = i;
}
//For clarity
IEnumerable strings = numbers.Select<int, string>(j=>j.ToString());
string[] stringArray = strings.ToArray<string>();
string output = string.Join(", ", stringArray);
Console.WriteLine(output);
//OR
//For brevity
Console.WriteLine(string.Join(", ", numbers.Select<int, string>(j => j.ToString()).ToArray<string>()));
$('.input').on('focus', function(){
$(this).val('');
});
$('[type="submit"]').on('click', function(){
$('.input').val('');
});
Stored procedure is the best way to do it. Because Meherzad's solution would work only if the data follows the same order.
If we have a table structure like this
col1 | col2 | col3
-----+------+------

Python calls __enter__
when execution enters the context of the with statement and it’s time to acquire the resource. When execution leaves the context again, Python calls __exit__
to free up the resource
Let's consider Context Managers and the “with” Statement in Python. Context Manager is a simple “protocol” (or interface) that your object needs to follow so it can be used with the with statement. Basically all you need to do is add enter and exit methods to an object if you want it to function as a context manager. Python will call these two methods at the appropriate times in the resource management cycle.
Let’s take a look at what this would look like in practical terms. Here’s how a simple implementation of the open() context manager might look like:
class ManagedFile:
def __init__(self, name):
self.name = name
def __enter__(self):
self.file = open(self.name, 'w')
return self.file
def __exit__(self, exc_type, exc_val, exc_tb):
if self.file:
self.file.close()
Our ManagedFile class follows the context manager protocol and now supports the with statement.
>>> with ManagedFile('hello.txt') as f:
... f.write('hello, world!')
... f.write('bye now')`enter code here`
Python calls enter when execution enters the context of the with statement and it’s time to acquire the resource. When execution leaves the context again, Python calls exit to free up the resource.
Writing a class-based context manager isn’t the only way to support the with statement in Python. The contextlib utility module in the standard library provides a few more abstractions built on top of the basic context manager protocol. This can make your life a little easier if your use cases matches what’s offered by contextlib.
I have tuned up previous code a little bit. First of all range.Changed hasn't work for me. After I changed range.Changed to richTextBox.TextChanged it turns out that TextChanged event handler can invoke SetDocumentXaml recursively, so I've provided protection against it. I also used XamlReader/XamlWriter instead of TextRange.
public class RichTextBoxHelper : DependencyObject
{
private static HashSet<Thread> _recursionProtection = new HashSet<Thread>();
public static string GetDocumentXaml(DependencyObject obj)
{
return (string)obj.GetValue(DocumentXamlProperty);
}
public static void SetDocumentXaml(DependencyObject obj, string value)
{
_recursionProtection.Add(Thread.CurrentThread);
obj.SetValue(DocumentXamlProperty, value);
_recursionProtection.Remove(Thread.CurrentThread);
}
public static readonly DependencyProperty DocumentXamlProperty = DependencyProperty.RegisterAttached(
"DocumentXaml",
typeof(string),
typeof(RichTextBoxHelper),
new FrameworkPropertyMetadata(
"",
FrameworkPropertyMetadataOptions.AffectsRender | FrameworkPropertyMetadataOptions.BindsTwoWayByDefault,
(obj, e) => {
if (_recursionProtection.Contains(Thread.CurrentThread))
return;
var richTextBox = (RichTextBox)obj;
// Parse the XAML to a document (or use XamlReader.Parse())
try
{
var stream = new MemoryStream(Encoding.UTF8.GetBytes(GetDocumentXaml(richTextBox)));
var doc = (FlowDocument)XamlReader.Load(stream);
// Set the document
richTextBox.Document = doc;
}
catch (Exception)
{
richTextBox.Document = new FlowDocument();
}
// When the document changes update the source
richTextBox.TextChanged += (obj2, e2) =>
{
RichTextBox richTextBox2 = obj2 as RichTextBox;
if (richTextBox2 != null)
{
SetDocumentXaml(richTextBox, XamlWriter.Save(richTextBox2.Document));
}
};
}
)
);
}

org.json.JSONObject#toMap() will do to work
This function should work whichever the locale and currency settings :
function getNumPrice(price, decimalpoint) {
var p = price.split(decimalpoint);
for (var i=0;i<p.length;i++) p[i] = p[i].replace(/\D/g,'');
return p.join('.');
}
This assumes you know the decimal point character (in my case the locale is set from PHP, so I get it with <?php echo cms_function_to_get_decimal_point(); ?>
).
It took me ages to work this one out, so for the benefit of searchers:
I had a bizarre issue whereby the application worked in debug, but gave the XamlParseException
once released.
After fixing the x86/x64 issue as detailed by Katjoek, the issue remained.
The issue was that a CEF tutorial said to bring down System.Windows.Interactivity
from NuGet (even thought it's in the Extensions section of references in .NET) and bringing down from NuGet sets specific version
to true
.
Once deployed, a different version of System.Windows.Interactivity
was being packed by a different application.
It's refusal to use a different version of the dll caused the whole application to crash with XamlParseException
.
Setting CSS width to 1% or 100% of an element according to all specs I could find out is related to the parent. Although Blink Rendering Engine (Chrome) and Gecko (Firefox) at the moment of writing seems to handle that 1% or 100% (make a columns shrink or a column to fill available space) well, it is not guaranteed according to all CSS specifications I could find to render it properly.
One option is to replace table with CSS4 flex divs:
https://css-tricks.com/snippets/css/a-guide-to-flexbox/
That works in new browsers i.e. IE11+ see table at the bottom of the article.
Changing the first letter to uppercase on the file's name and class name works.
file: controllers/Login.php
class: class Login extends CI_Controller { ... }
The file name, as the class name, should starts with capital letter. This rule applys to models too.
You can, once you escape the HTML correctly. This page shows what needs to be done.
If using PHP, you could use json_encode()
Hope this helps :)
Caesar's solution is the best in my opinion, but if you still insist to use the strcpy
function, then after you have your strings ready:
string a = "text";
string b = "image";
You can try either:
strcpy(a.data(), b.data());
or
strcpy(a.c_str(), b.c_str());
Just call either the data()
or c_str()
member functions of the std::string
class, to get the char*
pointer of the string object.
The strcpy()
function doesn't have overload to accept two std::string
objects as parameters.
It has only one overload to accept two char*
pointers as parameters.
Both data
and c_str
return what does strcpy()
want exactly.
I had the same problem. I enabled vtx in bios and it didn't worked. After a doublecheck in the bios I recogniced that the bios said that you have to poweroff (and realy power off) the computer. After that it worked. Heavy Pitfall :)
Suppose it could be useful in VisualStudio debugger which shows unordered object properties.

})({
b: 2,
a: 1,
c: 3
});

We can see that postgres build temp table and join with it
Another easy method to sort an array of strings consists by using the NSString description
property this way:
NSSortDescriptor *valueDescriptor = [NSSortDescriptor sortDescriptorWithKey:@"description" ascending:YES];
arrayOfSortedStrings = [arrayOfNotSortedStrings sortedArrayUsingDescriptors:@[valueDescriptor]];

The answers above point out how the block size can impact performance and suggest a common heuristic for its choice based on occupancy maximization. Without wanting to provide the criterion to choose the block size, it would be worth mentioning that CUDA 6.5 (now in Release Candidate version) includes several new runtime functions to aid in occupancy calculations and launch configuration, see
CUDA Pro Tip: Occupancy API Simplifies Launch Configuration
One of the useful functions is cudaOccupancyMaxPotentialBlockSize
which heuristically calculates a block size that achieves the maximum occupancy. The values provided by that function could be then used as the starting point of a manual optimization of the launch parameters. Below is a little example.
#include <stdio.h>
/************************/
/* TEST KERNEL FUNCTION */
/************************/
__global__ void MyKernel(int *a, int *b, int *c, int N)
{
int idx = threadIdx.x + blockIdx.x * blockDim.x;
if (idx < N) { c[idx] = a[idx] + b[idx]; }
}
/********/
/* MAIN */
/********/
void main()
{
const int N = 1000000;
int blockSize; // The launch configurator returned block size
int minGridSize; // The minimum grid size needed to achieve the maximum occupancy for a full device launch
int gridSize; // The actual grid size needed, based on input size
int* h_vec1 = (int*) malloc(N*sizeof(int));
int* h_vec2 = (int*) malloc(N*sizeof(int));
int* h_vec3 = (int*) malloc(N*sizeof(int));
int* h_vec4 = (int*) malloc(N*sizeof(int));
int* d_vec1; cudaMalloc((void**)&d_vec1, N*sizeof(int));
int* d_vec2; cudaMalloc((void**)&d_vec2, N*sizeof(int));
int* d_vec3; cudaMalloc((void**)&d_vec3, N*sizeof(int));
for (int i=0; i<N; i++) {
h_vec1[i] = 10;
h_vec2[i] = 20;
h_vec4[i] = h_vec1[i] + h_vec2[i];
}
cudaMemcpy(d_vec1, h_vec1, N*sizeof(int), cudaMemcpyHostToDevice);
cudaMemcpy(d_vec2, h_vec2, N*sizeof(int), cudaMemcpyHostToDevice);
float time;
cudaEvent_t start, stop;
cudaEventCreate(&start);
cudaEventCreate(&stop);
cudaEventRecord(start, 0);
cudaOccupancyMaxPotentialBlockSize(&minGridSize, &blockSize, MyKernel, 0, N);
// Round up according to array size
gridSize = (N + blockSize - 1) / blockSize;
cudaEventRecord(stop, 0);
cudaEventSynchronize(stop);
cudaEventElapsedTime(&time, start, stop);
printf("Occupancy calculator elapsed time: %3.3f ms \n", time);
cudaEventRecord(start, 0);
MyKernel<<<gridSize, blockSize>>>(d_vec1, d_vec2, d_vec3, N);
cudaEventRecord(stop, 0);
cudaEventSynchronize(stop);
cudaEventElapsedTime(&time, start, stop);
printf("Kernel elapsed time: %3.3f ms \n", time);
printf("Blocksize %i\n", blockSize);
cudaMemcpy(h_vec3, d_vec3, N*sizeof(int), cudaMemcpyDeviceToHost);
for (int i=0; i<N; i++) {
if (h_vec3[i] != h_vec4[i]) { printf("Error at i = %i! Host = %i; Device = %i\n", i, h_vec4[i], h_vec3[i]); return; };
}
printf("Test passed\n");
}
EDIT
The cudaOccupancyMaxPotentialBlockSize
is defined in the cuda_runtime.h
file and is defined as follows:
template<class T>
__inline__ __host__ CUDART_DEVICE cudaError_t cudaOccupancyMaxPotentialBlockSize(
int *minGridSize,
int *blockSize,
T func,
size_t dynamicSMemSize = 0,
int blockSizeLimit = 0)
{
return cudaOccupancyMaxPotentialBlockSizeVariableSMem(minGridSize, blockSize, func, __cudaOccupancyB2DHelper(dynamicSMemSize), blockSizeLimit);
}
The meanings for the parameters is the following
minGridSize = Suggested min grid size to achieve a full machine launch.
blockSize = Suggested block size to achieve maximum occupancy.
func = Kernel function.
dynamicSMemSize = Size of dynamically allocated shared memory. Of course, it is known at runtime before any kernel launch. The size of the statically allocated shared memory is not needed as it is inferred by the properties of func.
blockSizeLimit = Maximum size for each block. In the case of 1D kernels, it can coincide with the number of input elements.
Note that, as of CUDA 6.5, one needs to compute one's own 2D/3D block dimensions from the 1D block size suggested by the API.
Note also that the CUDA driver API contains functionally equivalent APIs for occupancy calculation, so it is possible to use cuOccupancyMaxPotentialBlockSize
in driver API code in the same way shown for the runtime API in the example above.

import config.logging_settings # @UnusedImport
Note the double space before the comment to avoid hitting other formatting warnings.
Also, depending on your IDE (if you're using one), there's probably an option to add the correct ignore rule (e.g., in Eclipse, pressing Ctrl + 1, while the cursor is over the warning, will auto-suggest @UnusedImport
).
Add this to the stylesheet:
table {
border-collapse: collapse;
}
The reason why it behaves this way is actually described pretty well in the specification:
There are two distinct models for setting borders on table cells in CSS. One is most suitable for so-called separated borders around individual cells, the other is suitable for borders that are continuous from one end of the table to the other.
... and later, for collapse
setting:
In the collapsing border model, it is possible to specify borders that surround all or part of a cell, row, row group, column, and column group.
This worked for me, using the latest release of Angular 2 (2.0.0-rc.1):

Yes you can upload your git repo from vs code. You have to get in the projects working directory and type git init in the terminal. Then add the files to your repository like you do with regular git commits.
If you already have checked out the code, the files are already indexed. After changing your git settings, say by running:
git config --global core.autocrlf input
you should refresh the indexes with
git rm --cached -r .
and re-write git index with
git reset --hard
Note: this is will remove your local changes, consider stashing them before you do this.
For me what worked was: (right click)project->android tools->clear lint markers. Although for some reason the Manifest reverted to the old (lower) minimum API level, but after I changed it back to the new (higher) API level there was no red error underline and the project now uses the new minimum API level.
Edit: Sorry, I see you were using Android Studio, not Eclipse. But I guess there is a similar 'clear lint markers' in Studio somewhere and it might solve the problem.

Apache2's server_access.log showed no entry when i tried to load WSDL so i added 'cache_wsdl' => WSDL_CACHE_NONE

You can find the documentation here, just choose "Customized URL" to see the details.
I just want to note that instead of using find and replace to change create procedure to alter procedure, you are just as well to use a drop, you can put it right at the top and it does require text searching.
IF exists (SELECT * FROM sys.objects

If you are sure it's there, I guess you could just drop it too, but I wouldn't recommend that. Don't forget the go, since create procedure must be the first and only statement in a batch.
Or the lazy approach:
IF OBJECT_ID(N'sp_name') is not null
DROP sp_name
GO

int a[] = { 1, 2, 3 }; // 3-element static size array
vector<int> v = { 1, 2, 3 }; // 3-element array but vector is resizeable in runtime
just if someone else is still struggeling with this problem, you may consider using
marshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);
to remove all of the XML declaration and just write your own String
at the beginning of your output stream / method
Try update the package.json file from
"@angular-devkit/build-angular": "^0.800.1"
to
"@angular-devkit/build-angular": "^0.12.4"
Then run npm install in the command line.
<ListView android:id="@id/android:list"

You could use the PHP in_array function
if( in_array( "bla" ,$yourarray ) )
{
echo "has bla";
}
Just change your port,might be your current port is in use by iis or some other server.
Use the Calendar-API:
// get Calendar instance
Calendar cal = Calendar.getInstance();
cal.setTime(new Date());
// substract 7 days
// If we give 7 there it will give 8 days back
cal.set(Calendar.DAY_OF_MONTH, cal.get(Calendar.DAY_OF_MONTH)-6);
// convert to date
Date myDate = cal.getTime();
Hope this helps. Have Fun!
$sum = 0;
foreach($group as $key=>$value)
{
$sum+= $value;
}
echo $sum;
change your codes as follows! it works for me. `
os.path.dirname(os.path.abspath("__file__"))
In that case you should use ListBox
control instead of dropdown and Set the SelectionMode
property to Multiple
<asp:ListBox runat="server" SelectionMode="Multiple" >
<asp:ListItem Text="test1"></asp:ListItem>
<asp:ListItem Text="test2"></asp:ListItem>
<asp:ListItem Text="test3"></asp:ListItem>
</asp:ListBox>
String.format (https://docs.oracle.com/javase/1.5.0/docs/api/java/util/Formatter.html#syntax)
In your case it will be:
String formatted = String.format("%03d", num);
to switchto a frame:
driver.switchTo.frame("Frame_ID");
to switch to the default again.
driver.switchTo().defaultContent();
If you want to ensure the values in the resultant List<Value>
are in the key-ordering of the input Map<Key, Value>
, you need to "go via" SortedMap
somehow.
Either start with a concrete SortedMap
implementation (Such as TreeMap
) or insert your input Map
into a SortedMap
before converting that to List
. e.g.:
Map<Key,Value> map;
List<Value> list = new ArrayList<Value>( new TreeMap<Key Value>( map ));
Otherwise you'll get whatever native ordering the Map
implementation provides, which can often be something other than the natural key ordering (Try Hashtable
or ConcurrentHashMap
, for variety).
If you really want to put the checkboxes inside the label, try adding an extra span tag, eg.
HTML
<div class="radio-toolbar">
<label><input type="radio" value="all" checked><span>All</span></label>
<label><input type="radio" value="false"><span>Open</span></label>
<label><input type="radio" value="true"><span>Archived</span></label>
</div>
CSS
.radio-toolbar input[type="radio"]:checked ~ * {
background:pink !important;
}
That will set the backgrounds for all siblings of the selected radio button.
Use:
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
iDisplayLength: -1
});
Or if using 1.10+
$('#example').dataTable({
paging: false
});
The option you should use is iDisplayLength:
$('#adminProducts').dataTable({
'iDisplayLength': 100
});
$('#table').DataTable({
"lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});
It will Load by default all entries.
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
iDisplayLength: -1
});
Or if using 1.10+
$('#example').dataTable({
paging: false
});
If you want to load by default 25 not all do this.
$('#example').dataTable({
aLengthMenu: [
[25, 50, 100, 200, -1],
[25, 50, 100, 200, "All"]
],
});
In my fairly complex scenario the accepted answer for how to do this in Chrome doesn't work for me. You may want to try the Firefox debugger instead (part of the Firefox developer tools), which shows all of the 'Sources', including those that are part of an iFrame

Using angular 1.5.9
I made it working like this by setting the window.location to the csv file download url. Tested and its working with the latest version of Chrome and IE11.
Angular
$scope.downloadStats = function downloadStats{
var csvFileRoute = '/stats/download';
$window.location = url;
}
html
<a target="_self" ng-click="downloadStats()"><i class="fa fa-download"></i> CSV</a>
In php set the below headers for the response:
$headers = [
'content-type' => 'text/csv',
'Content-Disposition' => 'attachment; filename="export.csv"',
'Cache-control' => 'private, must-revalidate, post-check=0, pre-check=0',
'Content-transfer-encoding' => 'binary',
'Expires' => '0',
'Pragma' => 'public',
];
try this
SELECT group_name, employees, surveys, COUNT( surveys ) AS test1,
concat(round(( surveys/employees * 100 ),2),'%') AS percentage
FROM a_test
GROUP BY employees
if you happened to use NLog in your ASP.net project, you can add a Debugger target:
<targets>
<target name="debugger" xsi:type="Debugger"
layout="${date:format=HH\:mm\:ss}|${pad:padding=5:inner=${level:uppercase=true}}|${message} "/>
and writes logs to this target for the levels you want:
<rules>
<logger name="*" minlevel="Trace" writeTo="debugger" />
now you have console output just like Jetty in "Output" window of VS, and make sure you are running in Debug Mode(F5).
git gc worked for me (in a new tab). Was getting this with every rebase. Thanks http://www.saintsatplay.com/blog/2016/02/dealing-with-git-unlink-file-errors#.W4WWNZMzZZJ
I was able to solve a similar problem like this:
The only disadvantage is that you have to re-import all your projects.
This function will return array with Header values as array keys.
function csv_to_array($file_name) {
$data = $header = array();
$i = 0;
$file = fopen($file_name, 'r');
while (($line = fgetcsv($file)) !== FALSE) {
if( $i==0 ) {
$header = $line;
} else {
$data[] = $line;
}
$i++;
}
fclose($file);
foreach ($data as $key => $_value) {
$new_item = array();
foreach ($_value as $key => $value) {
$new_item[ $header[$key] ] =$value;
}
$_data[] = $new_item;
}
return $_data;
}
The easiest way to do this, with excellent performance and compatibility with both old and new browsers, is to include either Lo-Dash or Underscore in your page.
Then you can use either _.size(object)
or _.keys(object).length
For your obj.Data
, you could test this with:
console.log( _.size(obj.Data) );
or:
console.log( _.keys(obj.Data).length );
Lo-Dash and Underscore are both excellent libraries; you would find either one very useful in your code. (They are rather similar to each other; Lo-Dash is a newer version with some advantanges.)
Alternatively, you could include this function in your code, which simply loops through the object's properties and counts them:
function ObjectLength( object ) {
var length = 0;
for( var key in object ) {
if( object.hasOwnProperty(key) ) {
++length;
}
}
return length;
};
You can test this with:
console.log( ObjectLength(obj.Data) );
That code is not as fast as it could be in modern browsers, though. For a version that's much faster in modern browsers and still works in old ones, you can use:
function ObjectLength_Modern( object ) {
return Object.keys(object).length;
}
function ObjectLength_Legacy( object ) {
var length = 0;
for( var key in object ) {
if( object.hasOwnProperty(key) ) {
++length;
}
}
return length;
}
var ObjectLength =
Object.keys ? ObjectLength_Modern : ObjectLength_Legacy;
and as before, test it with:
console.log( ObjectLength(obj.Data) );
This code uses Object.keys(object).length
in modern browsers and falls back to counting in a loop for old browsers.
But if you're going to all this work, I would recommend using Lo-Dash or Underscore instead and get all the benefits those libraries offer.
I set up a jsPerf that compares the speed of these various approaches. Please run it in any browsers you have handy to add to the tests.
Thanks to Barmar for suggesting Object.keys
for newer browsers in his answer.
You should put the image in webview and work with that. Zoom in / out controls are available in webview.
well, it's about 'performance' and 'speed' and in the simple word 'memory management' in a programming language.
in javascript we can put values in two layer: type1-objects
and type2-all other types of value such as string
& boolean
& etc
if you imagine memory as below squares which in every one of them just one type2-value can be saved:
every type2-value (green) is a single square while a type1-value (blue) is a group of them:
the point is that if you want to indicate a type2-value, the address is plain but if you want to do the same thing for type1-value that's not easy at all! :
and in a more complicated story:
so here references can rescue us:
while the green arrow here is a typical variable, the purple one is an object variable, so because the green arrow(typical variable) has just one task (and that is indicating a typical value) we don't need to separate it's value from it so we move the green arrow with the value of that wherever it goes and in all assignments, functions and so on ...
but we cant do the same thing with the purple arrow, we may want to move 'john' cell here or many other things..., so the purple arrow will stick to its place and just typical arrows that were assigned to it will move ...
a very confusing situation is where you can't realize how your referenced variable changes, let's take a look at a very good example:
let arr = [1, 2, 3, 4, 5]; //arr is an object now and a purple arrow is indicating it
let obj2 = arr; // now, obj2 is another purple arrow that is indicating the value of arr obj
let obj3 = ['a', 'b', 'c'];
obj2.push(6); // first pic below - making a new hand for the blue circle to point the 6
//obj2 = [1, 2, 3, 4, 5, 6]
//arr = [1, 2, 3, 4, 5, 6]
//we changed the blue circle object value (type1-value) and due to arr and obj2 are indicating that so both of them changed
obj2 = obj3; //next pic below - changing the direction of obj2 array from blue circle to orange circle so obj2 is no more [1,2,3,4,5,6] and it's no more about changing anything in it but we completely changed its direction and now obj2 is pointing to obj3
//obj2 = ['a', 'b', 'c'];
//obj3 = ['a', 'b', 'c'];
It is also important to encode the rest of the text in order to protect from possible script injection attacks
function insertTextWithLineBreaks(text, targetElement) {
var textWithNormalizedLineBreaks = text.replace('\r\n', '\n');
var textParts = textWithNormalizedLineBreaks.split('\n');
for (var i = 0; i < textParts.length; i++) {
targetElement.appendChild(document.createTextNode(textParts[i]));
if (i < textParts.length - 1) {
targetElement.appendChild(document.createElement('br'));
}
}
}
Here is a good explanation of your problem with the solution.
SetUp your HADOOP_HOME environment variable on the OS level or programmatically:
System.setProperty("hadoop.home.dir", "full path to the folder with winutils");

Here I have written few steps for How to Get RegID and Notification starting from scratch
You can find complete tutorial in below URL link
Code snip to get Registration ID (Device Token for Push Notification).
Configure project for GCM
For enable GCM in our project we need to add few permission in our manifest file Go to AndroidManifest.xml and add below code Add Permission
<uses-permission android:name="android.permission.INTERNET”/>
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name=“.permission.RECEIVE" />
<uses-permission android:name=“<your_package_name_here>.permission.C2D_MESSAGE" />
<permission android:name=“<your_package_name_here>.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
Add GCM Broadcast Receiver declaration
add GCM Broadcast Receiver declaration in your application tag
<application
<receiver
android:name=".GcmBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" ]]>
<intent-filter]]>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="" />
</intent-filter]]>
</receiver]]>
<application/>
Add GCM Servie declaration
<application
<service android:name=".GcmIntentService" />
<application/>
Now Go to your Launch/Splash Activity
Add Constants and Class Variables
private final static int PLAY_SERVICES_RESOLUTION_REQUEST = 9000;
public static final String EXTRA_MESSAGE = "message";
public static final String PROPERTY_REG_ID = "registration_id";
private static final String PROPERTY_APP_VERSION = "appVersion";

}
private static int getAppVersion(Context context)
{
try
{
PackageInfo packageInfo = context.getPackageManager()
.getPackageInfo(context.getPackageName(), 0);
return packageInfo.versionCode;
}
catch (NameNotFoundException e)
{
throw new RuntimeException("Could not get package name: " + e);
}
}
private void registerInBackground()

}
regid = gcm.register(SENDER_ID); Log.d(TAG, "########################################");
Log.d(TAG, "Current Device's Registration ID is: "+msg);
}
catch (IOException ex)
{
msg = "Error :" + ex.getMessage();
}
return null;
} protected void onPostExecute(Object result)
{ //to do here };
}.execute(null, null, null);
}
Note : please store REGISTRATION_KEY, it is important for sending PN Message to GCM also keep in mine this will be unique for all device, by using this only GCM will send Push Notification.
Add GCM Broadcast Receiver Class
As we have already declared “GcmBroadcastReceiver.java” in our Manifest file, So lets create this class update receiver class code this way
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent)
{ ComponentName comp = new ComponentName(context.getPackageName(),
GcmIntentService.class.getName()); startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
Toast.makeText(context, “wow!! received new push notification", Toast.LENGTH_LONG).show();
}
}
Add GCM Service Class
As we have already declared “GcmBroadcastReceiver.java” in our Manifest file, So lets create this class update receiver class code this way
public class GcmIntentService extends IntentService
{ public static final int NOTIFICATION_ID = 1; private NotificationManager mNotificationManager; private final static String TAG = "GcmIntentService"; public GcmIntentService() {
super("GcmIntentService");
} @Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
Log.d(TAG, "Notification Data Json :" + extras.getString("message"));
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String messageType = gcm.getMessageType(intent); if (!extras.isEmpty()) { if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR
.equals(messageType)) {
sendNotification("Send error: " + extras.toString());
} else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
.equals(messageType)) {
sendNotification("Deleted messages on server: "
+ extras.toString()); // If it's a regular GCM message, do some work.
} else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE
.equals(messageType)) {
// This loop represents the service doing some work.
for (int i = 0; i < 5; i++) {
Log.d(TAG," Working... " + (i + 1) + "/5 @ "
+ SystemClock.elapsedRealtime()); try {
Thread.sleep(5000);
} catch (InterruptedException e) {
}
}
Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime());
sendNotification(extras.getString("message"));
}
} // Release the wake lock provided by the WakefulBroadcastReceiver.
GcmBroadcastReceiver.completeWakefulIntent(intent);
} // Put the message into a notification and post it.
// This is just one simple example of what you might choose to do with
// a GCM message.
private void sendNotification(String msg) { mNotificationManager = (NotificationManager) this
.getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, LaunchActivity.class), 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder( this)
.setSmallIcon(R.drawable.icon)
.setContentTitle("Ocutag Snap")
.setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
.setContentText(msg)
.setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE);
mBuilder.setContentIntent(contentIntent); mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}
}
my case was a little different - unintentionally I have changed owner of git repository (project.git directory in my case), changing owner back to the git user helped
According to the website, sizeof()
is an alias of count()
, so they should be running the same code. Perhaps sizeof()
has a little bit of overhead because it needs to resolve it to count()
? It should be very minimal though.
The awk solution is what I would use, but if you want to understand your problems with bash, here is a revised version of your script.
#!/bin/bash -vx
##config file with ip addresses like 10.10.10.1:80
file=config.txt
while read line ; do
##this line is not correct, should strip :port and store to ip var
ip=$( echo "$line" |cut -d\: -f1 )
ping $ip
done < ${file}
You could write your top line as
for line in $(cat $file) ; do ...
(but not recommended).
You needed command substitution $( ... )
to get the value assigned to $ip
reading lines from a file is usually considered more efficient with the while read line ... done < ${file}
pattern.
I hope this helps.
Well, I don't understand why are you used transaction in case when you make a select
.
Transaction is useful when you make changes (add, edit or delete) data from database.
Remove transaction unless you use insert
, update
or delete
statements
I have publish unofficial api's for same, it's contains more than just hotspot turn on/off
. link
For API's DOC - link.
There is nothing wrong with syntax of
$('#part' + number).html(text);
jQuery accepts a String (usually a CSS Selector) or a DOM Node as parameter to create a jQuery Object.
In your case you should pass a String to $()
that is
$(<a string>)
Make sure you have access to the variables number
and text
.
To test do:
function(){
alert(number + ":" + text);//or use console.log(number + ":" + text)
$('#part' + number).html(text);
});
If you see you dont have access, pass them as parameters to the function, you have to include the uual parameters for $.get and pass the custom parameters after them.

Trying to make some order:
it all works - all but the firefox bookmarking function. for some reason the 'window.sidebar.addPanel' is not a function for the debugger, though it is working fine.
The problem is that it takes its values from the calling <a ..>
tag: title as the bookmark name and href as the bookmark address.
so this is my code:
javascript:
$("#bookmarkme").click(function () {
var url = 'http://' + location.host; // i'm in a sub-page and bookmarking the home page
var name = "Snir's Homepage";
if (navigator.userAgent.toLowerCase().indexOf('chrome') > -1){ //chrome
alert("In order to bookmark go to the homepage and press "
+ (navigator.userAgent.toLowerCase().indexOf('mac') != -1 ?
'Command/Cmd' : 'CTRL') + "+D.")
}
else if (window.sidebar) { // Mozilla Firefox Bookmark
//important for firefox to add bookmarks - remember to check out the checkbox on the popup
$(this).attr('rel', 'sidebar');
//set the appropriate attributes
$(this).attr('href', url);
$(this).attr('title', name);
//add bookmark:
// window.sidebar.addPanel(name, url, '');
// window.sidebar.addPanel(url, name, '');
window.sidebar.addPanel('', '', '');
}
else if (window.external) { // IE Favorite
window.external.addFavorite(url, name);
}
return;
});
html:
<a id="bookmarkme" href="#" title="bookmark this page">Bookmark This Page</a>
In internet explorer there is a different between 'addFavorite':
<a href="javascript:window.external.addFavorite('http://tiny.cc/snir','snir-site')">..</a>
and 'AddFavorite': <span onclick="window.external.AddFavorite(location.href, document.title);">..</span>
.
example here: http://www.yourhtmlsource.com/javascript/addtofavorites.html
Important, in chrome we can't add bookmarks using js (aspnet-i): http://www.codeproject.com/Questions/452899/How-to-add-bookmark-in-Google-Chrome-Opera-and-Saf

pgModeler can generate nice ER diagram from PostgreSQL databases.
It seems there is no manual, but it is easy enough without manual. It's QT application. AFAIK, Fedora and Ubuntu has package. (pgmodeler)
In the latest version of pgModeler (0.9.1) the trial version allows you to create ERD (the design button is not disabled). To do so:
a) When a cdecl function is called by the caller, how does a caller know if it should free up the stack?
The cdecl
modifier is part of the function prototype (or function pointer type etc.) so the caller get the info from there and acts accordingly.
b) If a function which is declared as stdcall calls a function(which has a calling convention as cdecl), or the other way round, would this be inappropriate?
No, it's fine.
c) In general, can we say that which call will be faster - cdecl or stdcall?
In general, I would refrain from any such statements. The distinction matters eg. when you want to use va_arg functions. In theory, it could be that stdcall
is faster and generates smaller code because it allows to combine popping the arguments with popping the locals, but OTOH with cdecl
, you can do the same thing, too, if you're clever.
The calling conventions that aim to be faster usually do some register-passing.
The following is an instantiation of the various "just print it" suggestions. I found it instructive.
#include "stdio.h"
int main() {
static int x = 5;
static int *p = &x;
printf("(int) p => %d\n",(int) p);
printf("(int) p++ => %d\n",(int) p++);
x = 5; p = &x;
printf("(int) ++p => %d\n",(int) ++p);
x = 5; p = &x;
printf("++*p => %d\n",++*p);
x = 5; p = &x;
printf("++(*p) => %d\n",++(*p));
x = 5; p = &x;
printf("++*(p) => %d\n",++*(p));
x = 5; p = &x;
printf("*p++ => %d\n",*p++);
x = 5; p = &x;
printf("(*p)++ => %d\n",(*p)++);
x = 5; p = &x;
printf("*(p)++ => %d\n",*(p)++);
x = 5; p = &x;
printf("*++p => %d\n",*++p);
x = 5; p = &x;
printf("*(++p) => %d\n",*(++p));
return 0;
}
It returns
(int) p => 256688152
(int) p++ => 256688152
(int) ++p => 256688156
++*p => 6
++(*p) => 6
++*(p) => 6
*p++ => 5
(*p)++ => 5
*(p)++ => 5
*++p => 0
*(++p) => 0
I cast the pointer addresses to int
s so they could be easily compared.
I compiled it with GCC.
ConcurrentLinkedQueue
If you don't care about having index-based access and just want the insertion-order-preserving characteristics of a List, you could consider a java.util.concurrent.ConcurrentLinkedQueue
. Since it implements Iterable, once you've finished adding all the items, you can loop over the contents using the enhanced for syntax:
Queue<String> globalQueue = new ConcurrentLinkedQueue<String>();
//Multiple threads can safely call globalQueue.add()...
for (String href : globalQueue) {
//do something with href
}
Just a complement to other answers and some clarification, if you are allowed to use C99.

Some of my preferences:
_Bool

looks better than the keyword _Bool
.bool
and _Bool
are: false
or true
. Assigning 0
or 1
instead of false
or true
is valid, but is harder to read and understand the logic flow.Some info from the standard:
_Bool
is NOT unsigned int
, but is part of the group unsigned integer types. It is large enough to hold the values 0
or 1
.bool
true
and false
but sure is not a good idea. This ability is considered obsolescent and will be removed in future._Bool
or bool
, if the scalar value is equal to 0
or compares to 0
it will be 0
, otherwise the result is 1
: _Bool x = 9;
9
is converted to 1
when assigned to x
._Bool
is 1 byte (8 bits), usually the programmer is tempted to try to use the other bits, but is not recommended, because the only guaranteed that is given is that only one bit is use to store data, not like type char
that have 8 bits available.You can't convert binary data to String. As a solution you can encode binary data and then convert to String. For example, look at this How do you convert binary data to Strings and back in Java?
With LINQ (.NET 3.5, C# 3)
var distinctNames = ( from row in DataTable.AsEnumerable()
select row.Field<string>("Name")).Distinct();
foreach (var name in distinctNames ) { Console.WriteLine(name); }
I was about to advise to extract all the files at the same level, then to make a jar out of the result, since the package system should keep them neatly separated. That would be the manual way, I suppose the tools indicated by Steve will do that nicely.
I didnt test it and dont know were you need it, but:
$order = new WC_Order(post->ID);
echo $order->get_order_number();
Let me know if it works. I belive order number echoes with the "#" but you can split that if only need only the number.
You can change the index as explained already using set_index
.
You don't need to manually swap rows with columns, there is a transpose (data.T
) method in pandas that does it for you:
> df = pd.DataFrame([['ABBOTSFORD', 427000, 448000],
['ABERFELDIE', 534000, 600000]],
columns=['Locality', 2005, 2006])
> newdf = df.set_index('Locality').T
> newdf
Locality ABBOTSFORD ABERFELDIE
2005 427000 534000
2006 448000 600000
then you can fetch the dataframe column values and transform them to a list:
> newdf['ABBOTSFORD'].values.tolist()
[427000, 448000]
Try saving the file as Excel Workbook ONLY. NOT any other format. It worked for me. I was getting the same error.
>>> import itertools
>>> int(''.join(itertools.takewhile(lambda s: s.isdigit(), string1)))
we can directly see the indexes on to the table if we know the index name with below :
select * from all_indexes where index_name= 'your index'
to me, i just do this :
rm -rf ~/.ssh/known_hosts
then :
i just ssh to the target host and all will be okay. This only if you dont know, what permission and the default owner of "known_hosts" file.
This should do the trick
public static IEnumerable<T> FindVisualChildren<T>(DependencyObject depObj) where T : DependencyObject
{
if (depObj != null)
{
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)
{
DependencyObject child = VisualTreeHelper.GetChild(depObj, i);
if (child != null && child is T)
{
yield return (T)child;
}
foreach (T childOfChild in FindVisualChildren<T>(child))
{
yield return childOfChild;
}
}
}
}
then you enumerate over the controls like so
foreach (TextBlock tb in FindVisualChildren<TextBlock>(window))
{
// do something with tb here
}
To Hide both Title and Action bar I did this:
In activity tag of Manifest:
android:theme="@style/AppTheme.NoActionBar"
In Activity.java before setContentView:
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
i.e.,
//Remove title bar
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
//Remove notification bar
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
NOTE: You need to keep these lines before setContentView
Just call it using super.
public void myMethod()
{
// B stuff
super.myMethod();
// B stuff
}
You are overwriting the start
date object with the value
of a DOM Element with an id of Startdate
.
This should work:
var start = new Date(document.getElementById('Stardate').value);
var y = start.getFullYear();
I think this comes from from the waterfall development days, where the actual development phase of a project could be as little as 20-30% of the total project time. Take the total lines of code and divide by the entire project time and you'll get around 10 lines/day. Divide by just the coding period, and you'll get closer to what people are quoting.
If we think of getting name of items from any specific category then we can do that by specifying the class name of that category using css selector:
import requests ; from bs4 import BeautifulSoup
soup = BeautifulSoup(requests.get('https://www.flipkart.com/').text, "lxml")
for link in soup.select('div._2kSfQ4'):
print(link.text)
This is the partial search results:

$where = "name='Joe' AND status='boss' OR status='active'";
$this->db->where($where);
select Qty, vajan, Rate,Amt,nhamali,ncommission,ntolai from SalesDtl,SalesMSt where SalesDtl.PurEntryNo=1 and SalesMST.SaleDate= (22/03/2014) and SalesMST.SaleNo= SalesDtl.SaleNo;
That should work.
I know there are a few configurations to use the static contents, but my solution is that I just create a bulk web-application folder within your tomcat. This "bulk webapp" is only serving all the static-contents without serving apps. This is pain-free and easy solution for serving static contents to your actual spring webapp.
For example, I'm using two webapp folders on my tomcat.
If I want to use javascript, I simply add the URI for my javascript file.
EX> /resources/path/to/js/myjavascript.js
For static images, I'm using the same method.
EX> /resources/path/to/img/myimg.jpg
Last, I put "security-constraint" on my tomcat to block the access to actual directory. I put "nobody" user-roll to the constraint so that the page generates "403 forbidden error" when people tried to access the static-contents path.
So far it works very well for me. I also noticed that many popular websites like Amazon, Twitter, and Facebook they are using different URI for serving static-contents. To find out this, just right click on any static content and check their URI.
There is a library at https://sourceforge.net/projects/stochunit/ for handling selection of ranges.
StochIntegerSelector randomIntegerSelector = new StochIntegerSelector();
randomIntegerSelector.setMin(-1);
randomIntegerSelector.setMax(1);
Integer selectInteger = randomIntegerSelector.selectInteger();
It has edge inclusion/preclusion.
To Disable scroll use this
webView.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event)
{
return (event.getAction() == MotionEvent.ACTION_MOVE);
}
});
No. As the documentation shows, you can only grant access to one object at a time.
Great answer from Simon, but for me it was easier to think about reverse case.
When do 2 ranges not overlap? They don't overlap when one of them starts after the other one ends:
dont_overlap = x2 < y1 || x1 > y2
Now it easy to express when they do overlap:
overlap = !dont_overlap = !(x2 < y1 || x1 > y2) = (x2 >= y1 && x1 <= y2)
