Swift 5
Cant fetch data from your api.
Easiest way to parse json is Use Decodable
protocol. Or Codable
(Encodable & Decodable
).
For ex:
let json = """
{
"dueDate": {
"year": 2021,
"month": 2,
"day": 17
}
}
"""
struct WrapperModel: Codable {
var dueDate: DueDate
}
struct DueDate: Codable {
var year: Int
var month: Int
var day: Int
}
let jsonData = Data(json.utf8)
let decoder = JSONDecoder()
do {
let model = try decoder.decode(WrapperModel.self, from: jsonData)
print(model)
} catch {
print(error.localizedDescription)
}
public ActionResult ActionName(string ReqParam1, string ReqParam2, string ReqParam3, string ReqParam4)
{
this.ControllerContext.HttpContext.Response.Headers.Add("Access-Control-Allow-Origin","*");
/*
--Your code goes here --
*/
return Json(new { ReturnData= "Data to be returned", Success=true }, JsonRequestBehavior.AllowGet);
}
First case:
A normal product lookup would look like this
http://our.api.com/product/1
So Im thinking that best practice would be for you to do this
http://our.api.com/Product/101404,7267261
Second Case
Search with querystring parameters - fine like this. I would be tempted to combine terms with AND and OR instead of using []
.
PS This can be subjective, so do what you feel comfortable with.
The reason for putting the data in the url is so the link can pasted on a site/ shared between users. If this isnt an issue, by all means use a JSON/ POST instead.
EDIT: On reflection I think this approach suits an entity with a compound key, but not a query for multiple entities.
There is a reason why using underscores was considered being bad style in the old days. When a runtime compiler was something unaffordable and monitors came with astonishing 320x240 pixel resolution it was often not easy to differentiate between _name
and __name
.
$host
is a variable of the Core module.
$host
This variable is equal to line Host in the header of request or name of the server processing the request if the Host header is not available.
This variable may have a different value from $http_host in such cases: 1) when the Host input header is absent or has an empty value, $host equals to the value of server_name directive; 2)when the value of Host contains port number, $host doesn't include that port number. $host's value is always lowercase since 0.8.17.
$http_host
is also a variable of the same module but you won't find it with that name because it is defined generically as $http_HEADER
(ref).
$http_HEADER
The value of the HTTP request header HEADER when converted to lowercase and with 'dashes' converted to 'underscores', e.g. $http_user_agent, $http_referer...;
Summarizing:
$http_host
equals always the HTTP_HOST
request header.$host
equals $http_host
, lowercase and without the port number (if present), except when HTTP_HOST
is absent or is an empty value. In that case, $host
equals the value of the server_name
directive of the server which processed the request.Regarding the 64-bit system wanting 32-bit support. I don't find it so bizarre:
Although deployed to a 64-bit system, this doesn't mean all the referenced assemblies are necessarily 64-bit Crystal Reports assemblies. Further to that, the Crystal Reports assemblies are largely just wrappers to a collection of legacy DLLs upon which they are based. Many 32-bit DLLs are required by the primarily referenced assembly. The error message "can not load the assembly" involves these DLLs as well. To see visually what those are, go to www.dependencywalker.com and run 'Depends' on the assembly in question, directly on that IIS server.
ScriptManager
control can also be used to reference javascript files. One catch is that the ScriptManager
control needs to be place inside the form
tag. I myself prefer ScriptManager
control and generally place it just above the closing form
tag.
<asp:ScriptManager ID="sm" runat="server">
<Scripts>
<asp:ScriptReference Path="~/Scripts/yourscript.min.js" />
</Scripts>
</asp:ScriptManager>
You cannot empty an array as such, it always contains the same amount of data.
In a bigger context the data in the array may represent an empty list of items, but that has to be defined in addition to the array. The most common ways to do this is to keep a count of valid items (see the answer by pmg) or for strings to terminate them with a zero character (the answer by Felix). There are also more complicated ways, for example a ring buffer uses two indices for the positions where data is added and removed.
I know I'm resurrecting an ancient question, but I was trying to solve this problem today and have an alternate solution. Toggling caching when I want to test was not really acceptable for me, and as others mentioned, hard refreshing (ctrl+shift+r) doesn't always work.
Instead, I opted to put the following in my vhost.conf file (can also be done in .htaccess) on my dev environment:
<FilesMatch "\.(js|css)$">
FileETag None
<IfModule mod_headers.c>
Header unset ETag
Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
</IfModule>
</FilesMatch>
On my dev environment, this ensures that js and css are always retrieved. Additionally it doesn't affect the rest of my browsing, and it also works for all browsers, so testing in chrome / ie etc is also easy.
Found the snippet here, some other handy apache tricks as well: http://www.askapache.com/htaccess/using-http-headers-with-htaccess.html#prevent-caching-with-htaccess
To make sure that my clients always see the latest version on production, we increment the query string on the js include on each update, ie
jquery.somefile.js?v=0.5
This forces my clients' browsers to update their local cache when they see a new querystring, but then caches the new copy until the file is updated again
The window
is the actual global object.
The screen
is the screen, it contains properties about the user's display.
The document
is where the DOM is.
Display images and text paragraphs is not possible in a UITextView
or UILabel
, to this, you must use a UIWebView
.
Just add the item in the storyboard, link to your code, and call it to load the URL.
OBJ-C
NSString *fullURL = @"http://conecode.com";
NSURL *url = [NSURL URLWithString:fullURL];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[_viewWeb loadRequest:requestObj];
Swift
let url = NSURL (string: "http://www.sourcefreeze.com");
let requestObj = NSURLRequest(URL: url!);
viewWeb.loadRequest(requestObj);

Solve this using java ( UTF-16LE with BOM ):
String csvReportStr = getCsvReport();
byte[] data = Charset.forName("UTF-16LE").encode(csvReportStr)
.put(0, (byte) 0xFF)
.put(1, (byte) 0xFE)
.array();
Note that CSV file should use TAB
as separator. You can read the CSV file both on windows and MAC OS X.
Refer to: How do I encode/decode UTF-16LE byte arrays with a BOM?
You can try something like this:
Thread.getAllStackTraces().keySet().forEach((t) -> System.out.println(t.getName() + "\nIs Daemon " + t.isDaemon() + "\nIs Alive " + t.isAlive()));
and you can obviously get more thread characteristic if you need.
There is also a way to add an attribute to an XmlNode
object, that can be useful in some cases.
I found this other method on msdn.microsoft.com.
using System.Xml;
[...]
//Assuming you have an XmlNode called node
XmlNode node;
[...]
//Get the document object
XmlDocument doc = node.OwnerDocument;
//Create a new attribute
XmlAttribute attr = doc.CreateAttribute("attributeName");
attr.Value = "valueOfTheAttribute";
//Add the attribute to the node
node.Attributes.SetNamedItem(attr);
[...]
In CakePHP 1.3, use 'default'=>value
to select the default value in a select input:
$this->Form->input('Leaf.id', array('type'=>'select', 'label'=>'Leaf', 'options'=>$leafs, 'default'=>'3'));
Close... try:
select
Sum(case when rsp_ind = 0 then 1 Else 0 End) as 'New',
Sum(case when rsp_ind = 1 then 1 else 0 end) as 'Accepted'
from tb_a
I'm using rather specified charset (ISO-8859-2) because not every mail system (for example: http://10minutemail.com) can read UTF-8 mails. If you need this:
function utf8_to_latin2($str)
{
return iconv ( 'utf-8', 'ISO-8859-2' , $str );
}
function my_mail($to,$s,$text,$form, $reply)
{
mail($to,utf8_to_latin2($s),utf8_to_latin2($text),
"From: $form\r\n".
"Reply-To: $reply\r\n".
"X-Mailer: PHP/" . phpversion());
}
I have made another mailer function, because apple device could not read well the previous version.
function utf8mail($to,$s,$body,$from_name="x",$from_a = "[email protected]", $reply="[email protected]")
{
$s= "=?utf-8?b?".base64_encode($s)."?=";
$headers = "MIME-Version: 1.0\r\n";
$headers.= "From: =?utf-8?b?".base64_encode($from_name)."?= <".$from_a.">\r\n";
$headers.= "Content-Type: text/plain;charset=utf-8\r\n";
$headers.= "Reply-To: $reply\r\n";
$headers.= "X-Mailer: PHP/" . phpversion();
mail($to, $s, $body, $headers);
}
The "for-else" design is often overlooked. See: Python Docs "Control Flow in Loop":
Example
with open('foobar.file', 'rb') as f:
for line in f:
foo()
else:
# No more lines to be read from file
bar()
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" MaxWidth="200"/>
</Grid.ColumnDefinitions>
<TextBox Background="Azure" Text="Hello" />
</Grid>
If you want POSIX-compliance and consistency across different implementations of echo
and printf
, and/or shells other than just bash
:
seq(){ n=$1; while [ $n -le $2 ]; do echo $n; n=$((n+1)); done ;} # If you don't have it.
echo $(for each in $(seq 1 100); do printf "="; done)
...will produce the same output as perl -E 'say "=" x 100'
just about everywhere.
You can change the level to OFF which should get rid of all logging. According to the log4j website, valid levels in order of importance are TRACE, DEBUG, INFO, WARN, ERROR, FATAL. There is one undocumented level called OFF which is a higher level than FATAL, and turns off all logging.
You can also create an extra root logger to log nothing (level OFF), so that you can switch root loggers easily. Here's a post to get you started on that.
You might also want to read the Log4J FAQ, because I think turning off all logging may not help. It will certainly not speed up your app that much, because logging code is executed anyway, up to the point where log4j decides that it doesn't need to log this entry.
This implementation:
do=true
while $do || conditions; do
do=false
# your code ...
done
It works with a read loop, too, skipping the first read:
do=true
while $do || read foo; do
do=false
# your code ...
echo $foo
done
Sometime I use such class, when I need to return multiple values from a method. Of course, such object is short lived and with very limited visibility, so it should be OK.
main()
{
int i = 247593;
char str[10];
sprintf(str, "%d", i);
// Now str contains the integer as characters
}
Hope it will be helpful to you.
With EF or LINQ to SQL:
var item = db.Items.OrderByDescending(i => i.Value).FirstOrDefault();
With LINQ to Objects I suggest to use morelinq extension MaxBy
(get morelinq from nuget):
var item = items.MaxBy(i => i.Value);
I'm using .Net Core 2 mvc, this one work for me ( to get the previews page) :
HttpContext.Request.Headers["Referer"];
"SELECT Applicant.applicantId, Applicant.lastName, Applicant.firstName, Applicant.middleName, Applicant.status,Applicant.companyId, Company.name, Applicant.createDate FROM (Applicant INNER JOIN Company ON Applicant.companyId = Company.companyId) WHERE Applicant.createDate between '" +dateTimePicker1.Text.ToString() + "'and '"+dateTimePicker2.Text.ToString() +"'";
this is what i did!!
function my_get_tags_sitemap(){
if ( !function_exists('wp_tag_cloud') || get_option('cb2_noposttags')) return;
$unlinkTags = get_option('cb2_unlinkTags');
echo '<div class="tags"><h2>Tags</h2>';
$ret = []; // here you need to add array which you call inside implode function
if($unlinkTags)
{
$tags = get_tags();
foreach ($tags as $tag){
$ret[]= $tag->name;
}
//ERROR OCCURS HERE
echo implode(', ', $ret);
}
else
{
wp_tag_cloud('separator=, &smallest=11&largest=11');
}
echo '</div>';
}
If you're still getting this error message:
TS7016: Could not find a declaration file for module './myjsfile'
Then you might need to add the following to tsconfig.json
{
"compilerOptions": {
...
"allowJs": true,
"checkJs": false,
...
}
}
This prevents typescript from trying to apply module types to the imported javascript.
You can use %%:
printf("100%%");
The result is:
100%
FPM is a process manager to manage the FastCGI SAPI (Server API) in PHP.
Basically, it replaces the need for something like SpawnFCGI. It spawns the FastCGI children adaptively (meaning launching more if the current load requires it).
Otherwise, there's not much operating difference between it and FastCGI (The request pipeline from start of request to end is the same). It's just there to make implementing it easier.
I prefer something like the following:
type StringRef []byte
func (s StringRef) String() string {
return string(s[:])
}
…
// rather silly example, but ...
fmt.Printf("foo=%s\n",StringRef("bar"))
SELECT *
FROM DBA_OBJECTS
WHERE OBJECT_TYPE = 'VIEW'
I use ubuntu 16.04 and because I already had openJDK installed, this command have solved the problem. Don't forget that JavaFX is part of OpenJDK.
sudo apt-get install openjfx
There are two steps you can take:
I now found solution by using mysqli
instead of mysql
.
<?php
// enable error reporting
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
//connect to database
$connection = mysqli_connect("hostname", "user", "password", "db", "port");
//run the store proc
$result = mysqli_query($connection, "CALL StoreProcName");
//loop the result set
while ($row = mysqli_fetch_array($result)){
echo $row[0] . " - " . + $row[1];
}
I found that many people seem to have a problem with using mysql_connect, mysql_query and mysql_fetch_array
.
$query->num_rows()
The number of rows returned by the query. Note: In this example, $query is the variable that the query result object is assigned to:
$query = $this->db->query('SELECT * FROM my_table');
echo $query->num_rows();
I render context path to attribute of link tag with id="contextPahtHolder" and then obtain it in JS code. For example:
<html>
<head>
<link id="contextPathHolder" data-contextPath="${pageContext.request.contextPath}"/>
<body>
<script src="main.js" type="text/javascript"></script>
</body>
</html>
main.js
var CONTEXT_PATH = $('#contextPathHolder').attr('data-contextPath');
$.get(CONTEXT_PATH + '/action_url', function() {});
If context path is empty (like in embedded servlet container istance), it will be empty string. Otherwise it contains contextPath string
Here is my enableOk function for a jQuery dialog:
function enableOk(enable)
{
var dlgFirstButton = $('.ui-dialog-buttonpane').find('button:first');
if (enable) {
dlgFirstButton.attr('disabled', '');
dlgFirstButton.removeClass('ui-state-disabled');
} else {
dlgFirstButton.attr('disabled', 'disabled');
dlgFirstButton.addClass('ui-state-disabled');
}
}
The "first" button is the one furthest to the right. You both disable the button and set the dialog's disabled class, for the proper visual effect.
"final" guarantees that a variable must be initialized before end of object initializer code. Likewise "static final" guarantees that a variable will be initialized by the end of class initialization code. Omitting the "static" from your initialization code turns it into object initialization code; thus your variable no longer satisfies its guarantees.

To answer the question as asked (without repeating unduly what appears in other answers)
Lexers and parsers are not very different, as suggested by the accepted answer. Both are based on simple language formalisms: regular languages for lexers and, almost always, context-free (CF) languages for parsers. They both are associated with fairly simple computational models, the finite state automaton and the push-down stack automaton. Regular languages are a special case of context-free languages, so that lexers could be produced with the somewhat more complex CF technology. But it is not a good idea for at least two reasons.
A fundamental point in programming is that a system component should be buit with the most appropriate technology, so that it is easy to produce, to understand and to maintain. The technology should not be overkill (using techniques much more complex and costly than needed), nor should it be at the limit of its power, thus requiring technical contortions to achieve the desired goal.
That is why "It seems fashionable to hate regular expressions". Though they can do a lot, they sometimes require very unreadable coding to achieve it, not to mention the fact that various extensions and restrictions in implementation somewhat reduce their theoretical simplicity. Lexers do not usually do that, and are usually a simple, efficient, and appropriate technology to parse token. Using CF parsers for token would be overkill, though it is possible.
Another reason not to use CF formalism for lexers is that it might then be tempting to use the full CF power. But that might raise sructural problems regarding the reading of programs.
Fundamentally, most of the structure of program text, from which meaning is extracted, is a tree structure. It expresses how the parse sentence (program) is generated from syntax rules. Semantics is derived by compositional techniques (homomorphism for the mathematically oriented) from the way syntax rules are composed to build the parse tree. Hence the tree structure is essential. The fact that tokens are identified with a regular set based lexer does not change the situation, because CF composed with regular still gives CF (I am speaking very loosely about regular transducers, that transform a stream of characters into a stream of token).
However, CF composed with CF (via CF transducers ... sorry for the math), does not necessarily give CF, and might makes things more general, but less tractable in practice. So CF is not the appropriate tool for lexers, even though it can be used.
One of the major differences between regular and CF is that regular languages (and transducers) compose very well with almost any formalism in various ways, while CF languages (and transducers) do not, not even with themselves (with a few exceptions).
(Note that regular transducers may have others uses, such as formalization of some syntax error handling techniques.)
BNF is just a specific syntax for presenting CF grammars.
EBNF is a syntactic sugar for BNF, using the facilities of regular notation to give terser version of BNF grammars. It can always be transformed into an equivalent pure BNF.
However, the regular notation is often used in EBNF only to emphasize these parts of the syntax that correspond to the structure of lexical elements, and should be recognized with the lexer, while the rest with be rather presented in straight BNF. But it is not an absolute rule.
To summarize, the simpler structure of token is better analyzed with the simpler technology of regular languages, while the tree oriented structure of the language (of program syntax) is better handled by CF grammars.
I would suggest also looking at AHR's answer.
But this leaves a question open: Why trees?
Trees are a good basis for specifying syntax because
they give a simple structure to the text
there are very convenient for associating semantics with the text on the basis of that structure, with a mathematically well understood technology (compositionality via homomorphisms), as indicated above. It is a fundamental algebraic tool to define the semantics of mathematical formalisms.
Hence it is a good intermediate representation, as shown by the success of Abstract Syntax Trees (AST). Note that AST are often different from parse tree because the parsing technology used by many professionals (Such as LL or LR) applies only to a subset of CF grammars, thus forcing grammatical distorsions which are later corrected in AST. This can be avoided with more general parsing technology (based on dynamic programming) that accepts any CF grammar.
Statement about the fact that programming languages are context-sensitive (CS) rather than CF are arbitrary and disputable.
The problem is that the separation of syntax and semantics is arbitrary. Checking declarations or type agreement may be seen as either part of syntax, or part of semantics. The same would be true of gender and number agreement in natural languages. But there are natural languages where plural agreement depends on the actual semantic meaning of words, so that it does not fit well with syntax.
Many definitions of programming languages in denotational semantics place declarations and type checking in the semantics. So stating as done by Ira Baxter that CF parsers are being hacked to get a context sensitivity required by syntax is at best an arbitrary view of the situation. It may be organized as a hack in some compilers, but it does not have to be.
Also it is not just that CS parsers (in the sense used in other answers here) are hard to build, and less efficient. They are are also inadequate to express perspicuously the kinf of context-sensitivity that might be needed. And they do not naturally produce a syntactic structure (such as parse-trees) that is convenient to derive the semantics of the program, i.e. to generate the compiled code.
Remember that in order to query the IEnumerable you need to reference system.linq.
It will give you the extension object needed to do:
CaimsList.FirstOrDefault(x=>x.Type =="variableName").toString();
Jon Tan has done this with his site - http://jontangerine.com/ Everything including images has been declared in ems. Everything. This is how the desired effect is achieved. Text zoom and screen zoom yield almost the exact same result.
Make a bat file with the following in it:
copy /y C:\temp\log1k.txt C:\temp\log1k_copied.txt
However, I think there are issues if there are spaces in your directory names. Notice this was copied to the same directory, but that doesn't matter. If you want to see how it runs, make another bat file that calls the first and outputs to a log:
C:\temp\test.bat > C:\temp\test.log
(assuming the first bat file was called test.bat and was located in that directory)
I think the question asker is (was) thinking that git bash is a command like git init or git checkout. Git bash is not a command, it is an interface. I will also assume the asker is not a linux user because bash is very popular the unix/linux world. The name "bash" is an acronym for "Bourne Again SHell". Bash is a text-only command interface that has features which allow automated scripts to be run. A good analogy would be to compare bash to the new PowerShell interface in Windows7/8. A poor analogy (but one likely to be more readily understood by more people) is the combination of the command prompt and .BAT (batch) command files from the days of DOS and early versions of Windows.
REFERENCES:
The project facets should be derived automagically by the M2Eclipse plugin from the POM configuration. If you make some changes to the POM and need Eclipse to take them into account, right-click on your project, then go to Maven > Update Project Configuration. You should not set project facets manually.
Newer versions of svn support the --show-item
argument:
svn info --show-item revision
For the revision number of your local working copy, use:
svn info --show-item last-changed-revision
You can use os.system()
to execute a command line like this:
svn info | grep "Revision" | awk '{print $2}'
I do that in my nightly build scripts.
Also on some platforms there is a svnversion
command, but I think I had a reason not to use it. Ahh, right. You can't get the revision number from a remote repository to compare it to the local one using svnversion.
Remember that when you write:
MyArray = Range("A1:A5000")
you are really writing
MyArray = Range("A1:A5000").Value
You can also use names:
MyArray = Names("MyWSTable").RefersToRange.Value
But Value is not the only property of Range. I have used:
MyArray = Range("A1:A5000").NumberFormat
I doubt
MyArray = Range("A1:A5000").Font
would work but I would expect
MyArray = Range("A1:A5000").Font.Bold
to work.
I do not know what formats you want to copy so you will have to try.
However, I must add that when you copy and paste a large range, it is not as much slower than doing it via an array as we all thought.
Post Edit information
Having posted the above I tried by own advice. My experiments with copying Font.Color and Font.Bold to an array have failed.
Of the following statements, the second would fail with a type mismatch:
ValueArray = .Range("A1:T5000").Value
ColourArray = .Range("A1:T5000").Font.Color
ValueArray must be of type variant. I tried both variant and long for ColourArray without success.
I filled ColourArray with values and tried the following statement:
.Range("A1:T5000").Font.Color = ColourArray
The entire range would be coloured according to the first element of ColourArray and then Excel looped consuming about 45% of the processor time until I terminated it with the Task Manager.
There is a time penalty associated with switching between worksheets but recent questions about macro duration have caused everyone to review our belief that working via arrays was substantially quicker.
I constructed an experiment that broadly reflects your requirement. I filled worksheet Time1 with 5000 rows of 20 cells which were selectively formatted as: bold, italic, underline, subscript, bordered, red, green, blue, brown, yellow and gray-80%.
With version 1, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" using copy.
With version 2, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" by copying the value and the colour via an array.
With version 3, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" by copying the formula and the colour via an array.
Version 1 took an average of 12.43 seconds, version 2 took an average of 1.47 seconds while version 3 took an average of 1.83 seconds. Version 1 copied formulae and all formatting, version 2 copied values and colour while version 3 copied formulae and colour. With versions 1 and 2 you could add bold and italic, say, and still have some time in hand. However, I am not sure it would be worth the bother given that copying 21,300 values only takes 12 seconds.

In my case the reason of the error is library which was linked two times.
I use react-native
so it was linked automatically using react-native link
and manually in xcode.
This issue came for me due to the fact that .. i was running server with selenium-server-standalone-2.32.0 and client registered with selenium-server-standalone-2.37.0 .. When i made both selenium-server-standalone-2.32.0 and ran then things worked fine
You might be interested in a proposal for some new operators that are similar to the conditional operator. The null-safe operators will enable code like this:
String s = mayBeNull?.toString() ?: "null";
It would be especially convenient where auto-unboxing takes place.
Integer ival = ...; // may be null
int i = ival ?: -1; // no NPE from unboxing
It has been selected for further consideration under JDK 7's "Project Coin."
You can use the key
parameter to list.sort()
:
my_list.sort(key=lambda x: x[1])
or, slightly faster,
my_list.sort(key=operator.itemgetter(1))
(As with any module, you'll need to import operator
to be able to use it.)
The other solutions here didn't work for me so I had to use:
if(!$(event.target).is('#foo'))
{
// hide menu
}
TextView view = (TextView) findViewById(R.id.textView);
view.setText("Add your text here");
view.setVisibility(View.VISIBLE);
To specify a directory to search for (binary) libraries, you just use -L
:
-L/data[...]/lib
To specify the actual library name, you use -l
:
-lfoo # (links libfoo.a or libfoo.so)
To specify a directory to search for include files (different from libraries!) you use -I
:
-I/data[...]/lib
So I think what you want is something like
g++ -g -Wall -I/data[...]/lib testing.cpp fileparameters.cpp main.cpp -o test
These compiler flags (amongst others) can also be found at the GNU GCC Command Options manual:
int[] n=new int[5];
for (int i = 0; i < 5; i++)
{
n[i] = i + 100;
}
foreach (int j in n)
{
int i = j - 100;
Console.WriteLine("Element [{0}]={1}", i, j);
i++;
}
You can hide the download link and make the button click it.
<button onclick="document.getElementById('link').click()">Download!</button>
<a id="link" href="file.doc" download hidden></a>
I found a solution on Stack Overflow for Java program run configurations which also works for JUnit run configurations.
You can get the full command executed by your configuration on the Debug tab, or more specifically the Debug view.
- Run your application
- Go to your Debug perspective
- There should be an entry in there (in the Debug View) for the app you've just executed
- Right-click the node which references java.exe or javaw.exe and select Properties In the dialog that pops up you'll see the Command Line which includes all jars, parameters, etc
SHOW FULL PROCESSLIST
If you don't use FULL
, "only the first 100 characters of each statement are shown in the Info
field".
When using phpMyAdmin, you should also click on the "Full texts" option ("? T ?" on top left corner of a results table) to see untruncated results.
This solution uses ES5 existential quantifier Array#some
, which allows to stop the iteration, if a condition is met.
Opposit of Array#reduce
, it does not need to iterate all elements for one result.
Inside the callback, an absolute delta
between the searched value and actual item
is taken and compared with the last delta. If greater or equal, the iteration stops, because all other values with their deltas are greater than the actual value.
If the delta
in the callback is smaller, then the actual item is assigned to the result and the delta
is saved in lastDelta
.
Finally, smaller values with equal deltas are taken, like in the below example of 22
, which results in 2
.
If there is a priority of greater values, the delta check has to be changed from:
if (delta >= lastDelta) {
to:
if (delta > lastDelta) {
// ^^^ without equal sign
This would get with 22
, the result 42
(Priority of greater values).
This function needs sorted values in the array.

I had a problem with the answer by @mwaskorn, namely that
g.set_xticklabels(rotation=30)
fails, because this also requires the labels. A bit easier than the answer by @Aman is to just add
plt.xticks(rotation=45)
As far as I know, it doesn't matter which one you use. They're equivalent in the eyes of the compiler. Use whichever one you prefer. I normally use class.

I believe you are looking for the outline
CSS property (in conjunction with active and hover psuedo attributes):
/* turn it off completely */
select:active, select:hover {
outline: none
}
/* make it red instead (with with same width and style) */
select:active, select:hover {
outline-color: red
}
Full details of outline, outline-color, outline-style, and outline-width https://developer.mozilla.org/en-US/docs/Web/CSS/outline
This button will appear yellow initially. On hover it will turn orange. When you click it, it will turn red. I used :hover and :focus to adapt the style.

There is a Firebug-like tool already built into Chrome. Just right click anywhere on a page and choose "Inspect element" from the menu.

If you are using PNG format then it will not compress your image because PNG is a lossless format. use JPEG for compressing your image and use 0 instead of 100 in quality.
Quality Accepts 0 - 100
0 = MAX Compression (Least Quality which is suitable for Small images)
100 = Least Compression (MAX Quality which is suitable for Big images)
To solve a similar problem, I'm using groupby
:
print(f"Distinct entries: {len(df.groupby(['col1', 'col2']))}")
Whether that's appropriate will depend on what you want to do with the result, though (in my case, I just wanted the equivalent of COUNT DISTINCT
as shown).

In the OP's context:
SELECT town, total_users
FROM ( SELECT DISTINCT town FROM canada ) AS towns
CROSS JOIN ( SELECT COUNT(*) total_users FROM canada ) AS tot;
Since there is only one row from tot
, the CROSS JOIN
is not as voluminous as it might otherwise be.
The usual pattern is COUNT(*)
instead of COUNT(town)
. The latter implies checking town
for being not null, which is unnecessary in this context.

Add produces = "application/json"
in @RequestMapping
annotation like:
@RequestMapping(value = "api/login", method = RequestMethod.GET, produces = "application/json")
Hint: As a return value, i recommend to use ResponseEntity<List<T>>
type. Because the produced data in JSON body need to be an array or an object according to its specifications, rather than a single simple string. It may causes problems sometimes (e.g. Observables in Angular2).
Difference:
returned String
as json: "example"
returned List<String>
as json: ["example"]
Adding an actionable aspect to a few of the other answers:
Both can give exit codes - default or defined by the function, and the only 'default' is zero for success for both exit and return. Any status can have a custom number 0-255, including for success.
Return is used often for interactive scripts that run in the current shell, called with . script.sh
for example, and just returns you to your calling shell. The return code is then accessible to the calling shell - $?
gives you the defined return status.
Exit in this case also closes your shell (including SSH connections, if that's how you're working).
Exit is necessary if the script is executable and called from another script or shell and runs in a subshell. The exit codes then are accessible to the calling shell - return would give an error in this case.
You can use ngStyle
to set background for a div
<div [ngStyle]="{background-image: 'url(./images/' + trls.img + ')'}"></div>
or you can also use built in background style:
<div [style.background-image]="'url(/images/' + trls.img + ')'"></div>
pathinfo is an array. We can check directory name, file name, extension, etc.:
$path_parts = pathinfo('test.png');
echo $path_parts['extension'], "\n";
echo $path_parts['dirname'], "\n";
echo $path_parts['basename'], "\n";
echo $path_parts['filename'], "\n";

mapfile
and readarray
(which are synonymous) are available in Bash version 4 and above. If you have an older version of Bash, you can use a loop to read the file into an array:
arr=()
while IFS= read -r line; do
arr+=("$line")
done < file
In case the file has an incomplete (missing newline) last line, you could use this alternative:
arr=()
while IFS= read -r line || [[ "$line" ]]; do
arr+=("$line")

Well any Javascript object functions sort-of like a "map"
randomObject['hello'] = 'world';
Typically people build simple objects for the purpose:
var myMap = {};
// ...
myMap[newKey] = newValue;
edit — well the problem with having an explicit "put" function is that you'd then have to go to pains to avoid having the function itself look like part of the map. It's not really a Javascripty thing to do.
13 Feb 2014 — modern JavaScript has facilities for creating object properties that aren't enumerable, and it's pretty easy to do. However, it's still the case that a "put" property, enumerable or not, would claim the property name "put" and make it unavailable. That is, there's still only one namespace per object.
In my case I was missing 'www.' from the url I was pushing. It must be exact match, if you're working on www.test.com
, you must push to www.test.com
and not test.com
Use a regex: Regex.Match("\.(?\d+)")

For a new project select the home directory of the jdk
eg C:\Java\jdk1.7.0_99
or C:\Program Files\Java\jdk1.7.0_99
For an existing project.
1) You need to have a jdk
installed on the system.
for instance in
C:\Java\jdk1.7.0_99
2) go to project structure
under File
menu ctrl+alt+shift+S
3) SDKs
is located under Platform Settings
. Select it.
4) click the green +
up the top of the window.
5) select JDK
(I have to use keyboard to select it do not know why).
select the home directory for your jdk installation.
should be good to go.
actually, if you already know the property, this will do it...
for example:
<a href="test.html" style="color:white;zoom:1.2" id="MyLink"></a>
var txt = "";
txt = getStyle(InterTabLink);
setStyle(InterTabLink, txt.replace("zoom\:1\.2\;","");
function setStyle(element, styleText){
if(element.style.setAttribute)
element.style.setAttribute("cssText", styleText );
else
element.setAttribute("style", styleText );
}
/* getStyle function */
function getStyle(element){
var styleText = element.getAttribute('style');
if(styleText == null)
return "";
if (typeof styleText == 'string') // !IE
return styleText;
else // IE
return styleText.cssText;
}
Note that this only works for inline styles... not styles you've specified through a class or something like that...
Other note: you may have to escape some characters in that replace statement, but you get the idea.
T represents an object type of, it implies that you can give any type of. IList : if IList s=new IList; Now s.add("Always accept string.").

I've read a lot of answers for this but if someone is still confused and needs a plus ultra "laymans term" to explain IoC here is my take:
Imagine a parent and child talking to each other.
Without IoC:
*Parent: You can only speak when I ask you questions and you can only act when I give you permission.
Parent: This means, you can't ask me if you can eat, play, go to the bathroom or even sleep if I don't ask you.
Parent: Do you want to eat?
Child: No.
Parent: Okay, I'll be back. Wait for me.
Child: (Wants to play but since there's no question from the parent, the child can't do anything).
After 1 hour...
Parent: I'm back. Do you want to play?
Child: Yes.
Parent: Permission granted.
Child: (finally is able to play).
This simple scenario explains the control is centered to the parent. The child's freedom is restricted and highly depends on the parent's question. The child can ONLY speak when asked to speak, and can ONLY act when granted permission.
With IoC:
The child has now the ability to ask questions and the parent can respond with answers and permissions. Simply means the control is inverted! The child is now free to ask questions anytime and though there is still dependency with the parent regarding permissions, he is not dependent in the means of speaking/asking questions.
In a technological way of explaining, this is very similar to console/shell/cmd vs GUI interaction. (Which is answer of Mark Harrison above no.2 top answer). In console, you are dependent on the what is being asked/displayed to you and you can't jump to other menus and features without answering it's question first; following a strict sequential flow. (programmatically this is like a method/function loop). However with GUI, the menus and features are laid out and the user can select whatever it needs thus having more control and being less restricted. (programmatically, menus have callback when selected and an action takes place).
db.query(
TABLE_NAME,
new String[] { TABLE_ROW_ID, TABLE_ROW_ONE, TABLE_ROW_TWO },
TABLE_ROW_ID + "=" + rowID,
null, null, null, null, null
);
TABLE_ROW_ID + "=" + rowID
, here =
is the where
clause. To select all values you will have to give all column names:
or you can use a raw query like this
db.rawQuery("SELECT * FROM permissions_table WHERE name = 'Comics' ", null);
and here is a good tutorial for database.
Just to Elaborate an alternate method and a Use case for which it is helpful:
from datetime import datetime, timedelta print datetime.now() + timedelta(days=-1) # Here, I am adding a negative timedelta
from datetime import datetime, timedelta print datetime.now() + timedelta(days=5, hours=-5)
It can similarly be used with other parameters e.g. seconds, weeks etc
You can set timeouts for all connections made from the jvm by changing the following System-properties:
System.setProperty("sun.net.client.defaultConnectTimeout", "10000");
System.setProperty("sun.net.client.defaultReadTimeout", "10000");
Every connection will time out after 10 seconds.
Setting 'defaultReadTimeout' is not needed, but shown as an example if you need to control reading.
print("imageURLString = " + imageURLString!)
just use !
This works:
from datetime import date
today =date.today()
Output in this time: 2020-08-29
Additional:
this_year = date.today().year
this_month = date.today().month
this_day = date.today().day
print(today)
print(this_year)
print(this_month)
print(this_day)
UIKit
uses the topLayoutGuide & bottomLayoutGuide which is UIView
propertyiOS11+ uses safeAreaLayoutGuide which is also UIView
property
Enable Safe Area Layout Guide check box from file inspector.
Safe areas help you place your views within the visible portion of the overall interface.
In tvOS, the safe area also includes the screen’s overscan insets, which represent the area covered by the screen’s bezel.
Use safe areas as an aid to laying out your content like UIButton
etc.
When designing for iPhone X, you must ensure that layouts fill the screen and aren't obscured by the device's rounded corners, sensor housing, or the indicator for accessing the Home screen.
Make sure backgrounds extend to the edges of the display, and that vertically scrollable layouts, like tables and collections, continue all the way to the bottom.
The status bar is taller on iPhone X than on other iPhones. If your app assumes a fixed status bar height for positioning content below the status bar, you must update your app to dynamically position content based on the user's device. Note that the status bar on iPhone X doesn't change height when background tasks like voice recording and location tracking are active
print(UIApplication.shared.statusBarFrame.height)//44 for iPhone X, 20 for other iPhones
Height of home indicator container is 34 points.
Once you enable Safe Area Layout Guide you can see safe area constraints property listed in the interface builder.
You can set constraints with respective of self.view.safeAreaLayoutGuide
as-
ObjC:
self.demoView.translatesAutoresizingMaskIntoConstraints = NO;
UILayoutGuide * guide = self.view.safeAreaLayoutGuide;
[self.demoView.leadingAnchor constraintEqualToAnchor:guide.leadingAnchor].active = YES;
[self.demoView.trailingAnchor constraintEqualToAnchor:guide.trailingAnchor].active = YES;
[self.demoView.topAnchor constraintEqualToAnchor:guide.topAnchor].active = YES;
[self.demoView.bottomAnchor constraintEqualToAnchor:guide.bottomAnchor].active = YES;
Swift:
demoView.translatesAutoresizingMaskIntoConstraints = false
if #available(iOS 11.0, *) {
let guide = self.view.safeAreaLayoutGuide
demoView.trailingAnchor.constraint(equalTo: guide.trailingAnchor).isActive = true
demoView.leadingAnchor.constraint(equalTo: guide.leadingAnchor).isActive = true
demoView.bottomAnchor.constraint(equalTo: guide.bottomAnchor).isActive = true
demoView.topAnchor.constraint(equalTo: guide.topAnchor).isActive = true
} else {
NSLayoutConstraint(item: demoView, attribute: .leading, relatedBy: .equal, toItem: view, attribute: .leading, multiplier: 1.0, constant: 0).isActive = true
NSLayoutConstraint(item: demoView, attribute: .trailing, relatedBy: .equal, toItem: view, attribute: .trailing, multiplier: 1.0, constant: 0).isActive = true
NSLayoutConstraint(item: demoView, attribute: .bottom, relatedBy: .equal, toItem: view, attribute: .bottom, multiplier: 1.0, constant: 0).isActive = true
NSLayoutConstraint(item: demoView, attribute: .top, relatedBy: .equal, toItem: view, attribute: .top, multiplier: 1.0, constant: 0).isActive = true
}
You need the change those double quotation marks into singles.
ie. if (answer == 'y')

In SQL Server 2012 and above, you don't need to create a link. You can execute directly
SELECT * FROM [TARGET_DATABASE].dbo.[TABLE] AS _TARGET
I don't know whether previous versions of SQL Server work as well
So you use this:
var theDialog = $("#divDialog").dialog(opt);
theDialog.dialog("open");
and if you open a MVC Partial View in Dialog, you can create in index a hidden button and JQUERY click event:
$("#YourButton").click(function()
{
theDialog.dialog("open");
OR
theDialog.dialog("close");
});
then inside partial view html you call button trigger click like:
$("#YouButton").trigger("click")
see ya.
Assuming you're using winforms, default panel components does not offer you a way to disable the horizontal scrolling components. A workaround of this is to disable the auto scrolling and add a scrollbar yourself:
ScrollBar vScrollBar1 = new VScrollBar();
vScrollBar1.Dock = DockStyle.Right;
vScrollBar1.Scroll += (sender, e) => { panel1.VerticalScroll.Value = vScrollBar1.Value; };
panel1.Controls.Add(vScrollBar1);
Detailed discussion here.
Your $_POST array contains the invite array, so reading it out as
<?php
if(isset($_POST['invite'])){
$invite = $_POST['invite'];
echo $invite;
}
?>
won't work since it's an array. You have to loop through the array to get all of the values.
<?php
if(isset($_POST['invite'])){
if (is_array($_POST['invite'])) {
foreach($_POST['invite'] as $value){
echo $value;
}
} else {
$value = $_POST['invite'];
echo $value;
}
}
?>
whilst sometimes you might have multiple php versions, you might also have a held-back version of php-mysql.. do a sudo dpkg -l | grep mysql | grep php and compare what you get from php -v
Below are two answers. First is a suggestion to use a more secure/flexible solution like ssh/scp/sftp. Second is an explanation of how to run ftp in batch mode.
You really should use SSH/SCP/SFTP for this rather than FTP. SSH/SCP have the benefits of being more secure and working with public/private keys which allows it to run without a username or password.
You can send a single file:
scp <file to upload> <username>@<hostname>:<destination path>
Or a whole directory:
scp -r <directory to upload> <username>@<hostname>:<destination path>
For more details on setting up keys and moving files to the server with RSYNC, which is useful if you have a lot of files to move, or if you sometimes get just one new file among a set of random files, take a look at:
http://troy.jdmz.net/rsync/index.html
You can also execute a single command after sshing into a server:
From man ssh
ssh [...snipped...] hostname [command] If command is specified, it is executed on the remote host instead of a login shell.
So, an example command is:
ssh [email protected] bunzip file_just_sent.bz2
If you can use SFTP with keys to gain the benefit of a secured connection, there are two tricks I've used to execute commands.
First, you can pass commands using echo and pipe
echo "put files*.xml" | sftp -p -i ~/.ssh/key_name [email protected]
You can also use a batchfile with the -b
parameter:
sftp -b batchfile.txt ~/.ssh/key_name [email protected]
If you understand that FTP is insecure and more limited and you really really want to script it...
There's a great article on this at http://www.stratigery.com/scripting.ftp.html
#!/bin/sh
HOST='ftp.example.com'
USER='yourid'
PASSWD='yourpw'
FILE='file.txt'
ftp -n $HOST <<END_SCRIPT
quote USER $USER
quote PASS $PASSWD
binary
put $FILE
quit
END_SCRIPT
exit 0
The -n
to ftp ensures that the command won't try to get the password from the current terminal. The other fancy part is the use of a heredoc: the <<END_SCRIPT
starts the heredoc and then that exact same END_SCRIPT
on the beginning of the line by itself ends the heredoc. The binary
command will set it to binary mode which helps if you are transferring something other than a text file.
There should be a script named mvim in the root of the .bz2 file. Copy this somewhere into your $PATH ( /usr/local/bin would be good ) and you should be sorted.
I wrote a shellscript that solves this problem for multiple websites: https://github.com/eduardschaeli/wget-image-scraper
(Scrapes images from a list of urls with wget)
if you are using windows try to pass encoding='latin1', encoding='iso-8859-1' or encoding='cp1252' example:
csv_data = pd.read_csv(csvpath,encoding='iso-8859-1')
print(print(soup.encode('iso-8859-1')))
It's very, very easy to get your device size as well as take into account the orientation:
// grab the window frame and adjust it for orientation
UIView *rootView = [[[UIApplication sharedApplication] keyWindow]
rootViewController].view;
CGRect originalFrame = [[UIScreen mainScreen] bounds];
CGRect adjustedFrame = [rootView convertRect:originalFrame fromView:nil];
Only SVG with path information. you can't do that to the image.. as the path you can change stroke and fill information and you are done. like Illustrator
so: via CSS you can overwrite path fill
value
path { fill: orange; }
but if you want more flexible way as you want to change it with a text when having some hovering effect going on.. use
path { fill: currentcolor; }

do a

For ASP.NET 1.1, this is still due to someone posting more than 1000 form fields, but the setting must be changed in the registry rather than a config file. It should be added as a DWORD named MaxHttpCollectionKeys in the registry under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ASP.NET\1.1.4322.0
for 32-bit editions of Windows, and
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\ASP.NET\1.1.4322.0
for 64-bit editions of Windows.
Yes, you can do this by creating a DoubleStream
from the array, filtering out the negatives, and converting the stream back to an array. Here is an example:
double[] d = {8, 7, -6, 5, -4};
d = Arrays.stream(d).filter(x -> x > 0).toArray();
//d => [8, 7, 5]
If you want to filter a reference array that is not an Object[]
you will need to use the toArray
method which takes an IntFunction
to get an array of the original type as the result:
String[] a = { "s", "", "1", "", "" };
a = Arrays.stream(a).filter(s -> !s.isEmpty()).toArray(String[]::new);
pyPDF works fine (assuming that you're working with well-formed PDFs). If all you want is the text (with spaces), you can just do:
import pyPdf
pdf = pyPdf.PdfFileReader(open(filename, "rb"))
for page in pdf.pages:
print page.extractText()
You can also easily get access to the metadata, image data, and so forth.
A comment in the extractText code notes:
Locate all text drawing commands, in the order they are provided in the content stream, and extract the text. This works well for some PDF files, but poorly for others, depending on the generator used. This will be refined in the future. Do not rely on the order of text coming out of this function, as it will change if this function is made more sophisticated.
Whether or not this is a problem depends on what you're doing with the text (e.g. if the order doesn't matter, it's fine, or if the generator adds text to the stream in the order it will be displayed, it's fine). I have pyPdf extraction code in daily use, without any problems.
If you've got a cell filled with spaces or blanks, you can use:
=Len(Trim(A2)) = 0
if the cell you were testing was A2
The simplest way to get tooltips in most browsers is to set some text in the title attribute.
eg.
<img src="myimage.jpg" alt="a cat" title="My cat sat on a table" />
produces (hover your mouse over the image):
a cat http://www.imagechicken.com/uploads/1275939952008633500.jpg
Title attributes can be applied to most HTML elements.

I faced the same issue. Our application running on four application servers and due to invalid schema location mentioned on one of the web service WSDL, hung threads are generated on the servers . The appliucations got down frequently. After corrected the schema Location , the issue got resolved.
You can use DDC (Domain Directory Controller). It is a new, easy to use, Java SDK. You don't even need to know LDAP to use it. It exposes an object-oriented API instead.
You can find it here.

private static List<HttpMessageConverter<?>> getMessageConverters() {
List<HttpMessageConverter<?>> converters = new ArrayList<HttpMessageConverter<?>>();
converters.add(new MappingJacksonHttpMessageConverter());
return converters;

RestTemplate restTemplate = new RestTemplate();
restTemplate.setMessageConverters(getMessageConverters());
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
HttpEntity<String> entity = new HttpEntity<String>(headers);
//Page page = restTemplate.getForObject("http://graph.facebook.com/pivotalsoftware", Page.class);
ResponseEntity<Page> response =

If you want to extract structured data from Wikipedia, you may consider using DbPedia http://dbpedia.org/
It provides means to query data using given criteria using SPARQL and returns data from parsed Wikipedia infobox templates
Here is a quick example how it could be done in .NET http://www.kozlenko.info/blog/2010/07/20/executing-sparql-query-on-wikipedia-in-net/
There are some SPARQL libraries available for multiple platforms to make queries easier
This will return columns, datatypes, and indexes defined on the table:
--List all tables in DB
select * from sysobjects where xtype = 'U'
--Table Definition
sp_help TableName
This will return triggers defined on the table:
--Triggers in SQL Table
select * from sys.triggers where parent_id = object_id(N'SQLTableName')
OpenTBS can create DOCX dynamic documents in PHP using the technique of templates.
No temporary files needed, no command lines, all in PHP.
It can add or delete pictures. The created document can be produced as a HTML download, a file saved on the server, or as binary contents in PHP.
It can also merge OpenDocument files (ODT, ODS, ODF, ...)

arr.map((myArr, index) => {
console.log(`your index is -> ${index} AND value is ${myArr}`);
})
_x000D_

stockList.add("stock1");
stockList.add("stock2");
String[] stockArr = new String[stockList.size()];
stockArr = stockList.toArray(stockArr);
for(String s : stockArr)
System.out.println(s);

http://dev.mysql.com/doc/refman/5.0/en/group-by-functions.html#function%5Fgroup-concat
No because this fundamentally means that you will not be grouping anything. If you group by all columns (and have a properly defined table w/ a unique index) then SELECT * FROM table
is essentially the same thing as SELECT * FROM table GROUP BY *

To get the eth0
interface MAC address,
import psutil
nics = psutil.net_if_addrs()['eth0']
for interface in nics:
if interface.family == 17:
print(interface.address)
fetch('http://localhost/foo.txt')
.then(response => response.text())
.then((data) => {
console.log(data)
})
This code can sort a key-value map in both orders i.e. ascending and descending.
<K, V extends Comparable<V>> Map<K, V> sortByValues
(final Map<K, V> map, int ascending)
{
Comparator<K> valueComparator = new Comparator<K>() {
private int ascending;
public int compare(K k1, K k2) {
int compare = map.get(k2).compareTo(map.get(k1));
if (compare == 0) return 1;
else return ascending*compare;
}
public Comparator<K> setParam(int ascending)
{
this.ascending = ascending;
return this;
}
}.setParam(ascending);
Map<K, V> sortedByValues = new TreeMap<K, V>(valueComparator);
sortedByValues.putAll(map);
return sortedByValues;
}
As an example:
Map<Integer,Double> recommWarrVals = new HashMap<Integer,Double>();
recommWarrVals = sortByValues(recommWarrVals, 1); // Ascending order
recommWarrVals = sortByValues(recommWarrVals,-1); // Descending order
Different solution for those still having issues. Hopefully I can help those trying to reinstall Mysql. Note, It's a seek and destroy mission. So be weary. Assuming your root:
apt-get purge mysql*
apt-get purge dbconfig-common #the screen used for mysql password
find / -name *mysql* #delete any traces of mysql
#insert apt-get cleanups, autoremove,updates etc.
Originally, something leftover was interfering with my startup of mysqlserver-5.5. These commands ended up resolving the issue for myself.
Starting with v0.16.0
, DF.assign()
could be used to assign new columns (single/multiple) to a DF
. These columns get inserted in alphabetical order at the end of the DF
.
This becomes advantageous compared to simple assignment in cases wherein you want to perform a series of chained operations directly on the returned dataframe.
Consider the same DF
sample demonstrated by @DSM:
df = pd.DataFrame({"A": [1,2,3], "B": [2,3,4]})
df
Out[18]:
A B
0 1 2
1 2 3
2 3 4
df.assign(C="",D=np.nan)
Out[21]:
A B C D
0 1 2 NaN
1 2 3 NaN
2 3 4 NaN
Note that this returns a copy with all the previous columns along with the newly created ones. In order for the original DF
to be modified accordingly, use it like : df = df.assign(...)
as it does not support inplace
operation currently.
multipart/form-data
Note. Please consult RFC2388 for additional information about file uploads, including backwards compatibility issues, the relationship between "multipart/form-data" and other content types, performance issues, etc.
Please consult the appendix for information about security issues for forms.
The content type "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.
The content type "multipart/form-data" follows the rules of all multipart MIME data streams as outlined in RFC2045. The definition of "multipart/form-data" is available at the [IANA] registry.
A "multipart/form-data" message contains a series of parts, each representing a successful control. The parts are sent to the processing agent in the same order the corresponding controls appear in the document stream. Part boundaries should not occur in any of the data; how this is done lies outside the scope of this specification.
As with all multipart MIME types, each part has an optional "Content-Type" header that defaults to "text/plain". User agents should supply the "Content-Type" header, accompanied by a "charset" parameter.
application/x-www-form-urlencoded
This is the default content type. Forms submitted with this content type must be encoded as follows:
Control names and values are escaped. Space characters are replaced by +', and then reserved characters are escaped as described in [RFC1738], section 2.2: Non-alphanumeric characters are replaced by
%HH', a percent sign and two hexadecimal digits representing the ASCII code of the character. Line breaks are represented as "CR LF" pairs (i.e., %0D%0A').
The control names/values are listed in the order they appear in the document. The name is separated from the value by
=' and name/value pairs are separated from each other by `&'.
application/x-www-form-urlencoded
the body of the HTTP message sent to the server is essentially one giant query string -- name/value pairs are separated by the ampersand (&), and names are separated from values by the equals symbol (=). An example of this would be:
MyVariableOne=ValueOne&MyVariableTwo=ValueTwo
The content type "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.
psql "sslmode=require host=localhost port=2345 dbname=postgres" --username=some_user
According to the postgres psql documentation, only the connection parameters should go in the conninfo string(that's why in our example, --username is not inside that string)
Ok, you've declared junit
dependency for test
classes only (those that are in src/test/java
but you're trying to use it in main
classes (those that are in src/main/java
).
Either do not use it in main classes, or remove <scope>test</scope>
.
What about doing it this way
strgroupids = string.Join( ",", groupIds );
A lot cleaner.
It will append all elements inside groupIds
with a ','
between each, but it will not put a ','
at the end.
By now there are 4 different ways to document objects as parameters/types. Each has its own uses. Only 3 of them can be used to document return values, though.
For objects with a known set of properties (Variant A)
/**
* @param {{a: number, b: string, c}} myObj description
*/
This syntax is ideal for objects that are used only as parameters for this function and don't require further description of each property.
It can be used for @returns
as well.
For objects with a known set of properties (Variant B)
Very useful is the parameters with properties syntax:
/**
* @param {Object} myObj description
* @param {number} myObj.a description
* @param {string} myObj.b description
* @param {} myObj.c description
*/
This syntax is ideal for objects that are used only as parameters for this function and that require further description of each property.
This can not be used for @returns
.
For objects that will be used at more than one point in source
In this case a @typedef comes in very handy. You can define the type at one point in your source and use it as a type for @param
or @returns
or other JSDoc tags that can make use of a type.
/**
* @typedef {Object} Person
* @property {string} name how the person is called
* @property {number} age how many years the person lived
*/
You can then use this in a @param
tag:
/**
* @param {Person} p - Description of p
*/
Or in a @returns
:
/**
* @returns {Person} Description
*/
For objects whose values are all the same type
/**
* @param {Object.<string, number>} dict
*/
The first type (string) documents the type of the keys which in JavaScript is always a string or at least will always be coerced to a string. The second type (number) is the type of the value; this can be any type.
This syntax can be used for @returns
as well.
Resources
Useful information about documenting types can be found here:
https://jsdoc.app/tags-type.html
PS:
to document an optional value you can use []
:
/**
* @param {number} [opt_number] this number is optional
*/
or:
/**
* @param {number|undefined} opt_number this number is optional
*/
$ bundle update json
$ bundle install
Another way
=IF(SUMPRODUCT(--(NOT(ISERR(SEARCH({"Gingrich","Obama","Romney"},C1)))))>0,"1","")
Also, if you keep a list of values in, say A1 to A3, then you can use
=IF(SUMPRODUCT(--(NOT(ISERR(SEARCH($A$1:$A$3,C1)))))>0,"1","")
The wildcards are not necessary at all in the Search() function, since Search() returns the position of the found string.
>>> a='2010-01-31'
>>> a.split('-')
['2010', '01', '31']
>>> year,month,date=a.split('-')
>>> year
'2010'
>>> month
'01'
>>> date
'31'
If you want exactly 40 spaces before the string then you should just do:
printf(" %s\n", myStr );
If that is too dirty, you can do (but it will be slower than manually typing the 40 spaces):
printf("%40s%s", "", myStr );
If you want the string to be lined up at column 40 (that is, have up to 39 spaces proceeding it such that the right most character is in column 40) then do this:
printf("%40s", myStr);
You can also put "up to" 40 spaces AfTER the string by doing:
printf("%-40s", myStr);
I needed something similar for a task. This is the code I wrote: It calculates the next day and changes the time to whatever is required and finds seconds between currentTime and next scheduled time.
import datetime as dt
def my_job():
print "hello world"
nextDay = dt.datetime.now() + dt.timedelta(days=1)
dateString = nextDay.strftime('%d-%m-%Y') + " 01-00-00"
newDate = nextDay.strptime(dateString,'%d-%m-%Y %H-%M-%S')
delay = (newDate - dt.datetime.now()).total_seconds()
Timer(delay,my_job,()).start()
UPDATE 2: A useful set of regex functions including REGEXP_REPLACE have now been provided in MySQL 8.0. This renders reading on unnecessary unless you're constrained to using an earlier version.
UPDATE 1: Have now made this into a blog post: http://stevettt.blogspot.co.uk/2018/02/a-mysql-regular-expression-replace.html
The following expands upon the function provided by Rasika Godawatte but trawls through all necessary substrings rather than just testing single characters:

-- ------------------------------------------------------------------------------------
-- SELECT reg_replace(<subject>,
-- <pattern>,
-- <replacement>,
-- <greedy>,
-- <minMatchLen>,

-- where:
-- <subject> is the string to look in for doing the replacements
-- <pattern> is the regular expression to match against
-- <replacement> is the replacement string
-- <greedy> is TRUE for greedy matching or FALSE for non-greedy matching
-- <minMatchLen> specifies the minimum match length
-- <maxMatchLen> specifies the maximum match length
-- (minMatchLen and maxMatchLen are used to improve efficiency but are
-- optional and can be set to 0 or NULL if not known/required)
-- Example:
-- SELECT reg_replace(txt, '^[Tt][^ ]* ', 'a', TRUE, 2, 0) FROM tbl;

The function has been used to answer the following StackOverflow questions:
Date and time input is accepted in almost any reasonable format, including ISO 8601, SQL-compatible, traditional POSTGRES, and others. For some formats, ordering of month, day, and year in date input is ambiguous and there is support for specifying the expected ordering of these fields.
In other words: just write anything and it will work.
Or check this table with all the unambiguous formats.
Sample text:
Clinton said
Bush used crayons
Reagan forgot
Just omitting a Bush match:
$ perl -ne 'print if /^(Clinton|Reagan)/' textfile
Clinton said
Reagan forgot
Or if you really want to specify:
$ perl -ne 'print if /^(?!Bush)(Clinton|Reagan)/' textfile

It is a tricky matter to parse .csv files when the .csv file could be either comma separated strings, comma separated quoted strings, or a chaotic combination of the two. The solution I came up with allows for any of the three possibilities.
I created a method, ParseCsvRow() which returns an array from a csv string. I first deal with double quotes in the string by splitting the string on double quotes into an array called quotesArray. Quoted string .csv files are only valid if there is an even number of double quotes. Double quotes in a column value should be replaced with a pair of double quotes (This is Excel's approach). As long as the .csv file meets these requirements, you can expect the delimiter commas to appear only outside of pairs of double quotes. Commas inside of pairs of double quotes are part of the column value and should be ignored when splitting the .csv into an array.
My method will test for commas outside of double quote pairs by looking only at even indexes of the quotesArray. It also removes double quotes from the start and end of column values.
public static string[] ParseCsvRow(string csvrow)
{
const string obscureCharacter = "?";
if (csvrow.Contains(obscureCharacter)) throw new Exception("Error: csv row may not contain the " + obscureCharacter + " character");
var unicodeSeparatedString = "";
var quotesArray = csvrow.Split('"'); // Split string on double quote character
if (quotesArray.Length > 1)
{
for (var i = 0; i < quotesArray.Length; i++)
{
// CSV must use double quotes to represent a quote inside a quoted cell
// Quotes must be paired up
// Test if a comma lays outside a pair of quotes. If so, replace the comma with an obscure unicode character
if (Math.Round(Math.Round((decimal) i/2)*2) == i)
{
var s = quotesArray[i].Trim();
switch (s)
{
case ",":
quotesArray[i] = obscureCharacter; // Change quoted comma seperated string to quoted "obscure character" seperated string
break;
}
}
// Build string and Replace quotes where quotes were expected.
unicodeSeparatedString += (i > 0 ? "\"" : "") + quotesArray[i].Trim();
}
}
else
{
// String does not have any pairs of double quotes. It should be safe to just replace the commas with the obscure character
unicodeSeparatedString = csvrow.Replace(",", obscureCharacter);
}
var csvRowArray = unicodeSeparatedString.Split(obscureCharacter[0]);
for (var i = 0; i < csvRowArray.Length; i++)
{
var s = csvRowArray[i].Trim();
if (s.StartsWith("\"") && s.EndsWith("\""))
{
csvRowArray[i] = s.Length > 2 ? s.Substring(1, s.Length - 2) : ""; // Remove start and end quotes.
}
}
return csvRowArray;
}
One downside of my approach is the way I temporarily replace delimiter commas with an obscure unicode character. This character needs to be so obscure, it would never show up in your .csv file. You may want to put more handling around this.
You Can Follow These Steps.
pip install jupyterthemes
or pip install --upgrade jupyterthemes
to upgrade to latest version of theme.jt -l

for example jt -t solarizedl
This is what you are looking for:
$('#cf_1268591').attr("style", "pointer-events: none;");
Works like a charm.
Do the following thing if you want to use json as a http request and response. So we need to make changes in [context].xml
<!-- Configure to plugin JSON as request and response in method handler -->
<beans:bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
<beans:property name="messageConverters">
<beans:list>
<beans:ref bean="jsonMessageConverter"/>
</beans:list>
</beans:property>
</beans:bean>
<!-- Configure bean to convert JSON to POJO and vice versa -->
<beans:bean id="jsonMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
</beans:bean>
MappingJackson2HttpMessageConverter to the RequestMappingHandlerAdapter messageConverters so that Jackson API kicks in and converts JSON to Java Beans and vice versa. By having this configuration, we will be using JSON in request body and we will receive JSON data in the response.
I am also providing small code snippet for controller part:
@RequestMapping(value = EmpRestURIConstants.DUMMY_EMP, method = RequestMethod.GET)
public @ResponseBody Employee getDummyEmployee() {
logger.info("Start getDummyEmployee");
Employee emp = new Employee();
emp.setId(9999);
emp.setName("Dummy");
emp.setCreatedDate(new Date());
empData.put(9999, emp);
return emp;
}
So in above code emp object will directly convert into json as a response. same will happen for post also.
The best provider for http status code constants is likely to be Jetty's org.eclipse.jetty.http.HttpStatus class because:
Only thing I would improve: put the status code number in front of the text description in order to make auto-completion lookup more convient when you are starting with the code.
Editor warning: This solution is computationally inefficient and may bring down your connection for a large table.
NB - You need to do this first on a test copy of your table!
When I did it, I found that unless I also included AND n1.id <> n2.id
, it deleted every row in the table.
If you want to keep the row with the lowest id
value:
DELETE n1 FROM names n1, names n2 WHERE n1.id > n2.id AND n1.name = n2.name
If you want to keep the row with the highest id
value:
DELETE n1 FROM names n1, names n2 WHERE n1.id < n2.id AND n1.name = n2.name
I used this method in MySQL 5.1
Not sure about other versions.
Update: Since people Googling for removing duplicates end up here
Although the OP's question is about DELETE
, please be advised that using INSERT
and DISTINCT
is much faster. For a database with 8 million rows, the below query took 13 minutes, while using DELETE
, it took more than 2 hours and yet didn't complete.
INSERT INTO tempTableName(cellId,attributeId,entityRowId,value)
SELECT DISTINCT cellId,attributeId,entityRowId,value
FROM tableName;
i use "Versions", quite easy, but not free .
Using JODA:
PeriodFormatter periodFormat = new PeriodFormatterBuilder()
.minimumParsedDigits(2)
.appendHour() // 2 digits minimum
.appendSeparator(":")
.minimumParsedDigits(2)
.appendMinute() // 2 digits minimum
.appendSeparator(":")
.minimumParsedDigits(2)
.appendSecond()
.appendSeparator(".")
.appendMillis3Digit()
.toFormatter();
Period result = Period.parse(string, periodFormat);
return result.toStandardDuration().getMillis();
IMHO I disagree with RickNotFred's statement:
Popping a dialog when an EditText gets focus seems like a non-standard interface.
Displaying a dialog to edit the date when the use presses the an EditText is very similar to the default, which is to display a keyboard or a numeric key pad. The fact that the date is displayed with the EditText signals to the user that the date may be changed. Displaying the date as a non-editable TextView signals to the user that the date may not be changed.

In my case, it's because we tried to post a notification without specifying the NotificationChannel
:
public static final String NOTIFICATION_CHANNEL_ID_SERVICE = "com.mypackage.service";
public static final String NOTIFICATION_CHANNEL_ID_TASK = "com.mypackage.download_info";
public void initChannel(){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
nm.createNotificationChannel(new NotificationChannel(NOTIFICATION_CHANNEL_ID_SERVICE, "App Service", NotificationManager.IMPORTANCE_DEFAULT));
nm.createNotificationChannel(new NotificationChannel(NOTIFICATION_CHANNEL_ID_INFO, "Download Info", NotificationManager.IMPORTANCE_DEFAULT));
}
}
The best place to put above code is in onCreate()
method in the Application
class, so that we just need to declare it once for all:
public class App extends Application {
@Override
public void onCreate() {
super.onCreate();
initChannel();
}
}
After we set this up, we can use notification with the channelId
we just specified:
Intent i = new Intent(this, MainActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pi = PendingIntent.getActivity(this, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID_INFO);
.setContentIntent(pi)
.setWhen(System.currentTimeMillis())
.setContentTitle("VirtualBox.exe")
.setContentText("Download completed")
.setSmallIcon(R.mipmap.ic_launcher);
Then, we can use it to post a notification:
int notifId = 45;
NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
nm.notify(notifId, builder.build());
If you want to use it as foreground service's notification:
startForeground(notifId, builder.build());
gettimeofday() will probably do what you want.
If you're on Intel hardware, here's how to read the CPU real-time instruction counter. It will tell you the number of CPU cycles executed since the processor was booted. This is probably the finest-grained, lowest overhead counter you can get for performance measurement.
Note that this is the number of CPU cycles. On linux you can get the CPU speed from /proc/cpuinfo and divide to get the number of seconds. Converting this to a double is quite handy.

Recently had the issue on Xcode 11 beta 2:
If your target doesn't have the "Signing & Capabilities" tab (in my case only the test target had it), open the build settings for your project and click "All" instead of "Basic"/"Customised". Find signing under the settings and make sure you've got a Development team set up.
In .NET, I recommend to dynamically build the regular expression with the decimal separator of the current cultural context:
using System.Globalization;
...
NumberFormatInfo nfi = NumberFormatInfo.CurrentInfo;
Regex re = new Regex("^(?\\d+("
+ Regex.Escape(nfi.CurrencyDecimalSeparator)
+ "\\d{1,2}))$");
You might want to pimp the regexp by allowing 1000er separators the same way as the decimal separator.
ThomasH has already added a good answer, but I want to show what happens:
>>> a = [[1, 2], [3, 4]]
>>> [x for x in b for b in a]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'b' is not defined
>>> [x for b in a for x in b]
[1, 2, 3, 4]
>>> [x for x in b for b in a]
[3, 3, 4, 4]
I guess Python parses the list comprehension from left to right. This means, the first for
loop that occurs will be executed first.
The second "problem" of this is that b
gets "leaked" out of the list comprehension. After the first successful list comprehension b == [3, 4]
.
It varies from assembler to assembler. Most machines offer registers, which have symbolic names like R1, or EAX (the Intel x86), and have instruction names like "CMP" for compare. And for a compare instruction, you need another operand, sometimes a register, sometimes a literal. Often assemblers allow comments to the right of instruction.
An instruction line looks like:
<opcode> <register> <operand> ; comment
Your assembler may vary somewhat.
For the Microsoft X86 assembler, you can write:
CMP EAX, 23 ; compare register EAX with the constant 23
or
CMP EAX, XYZ ; compare register EAX with contents of memory location named XYZ
Often one can write complex "expressions" in the operand field that enable the instruction, if it has the capability, to address memory in variety of ways. But I think this answers your question.
You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.
Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String
'Assign data to first item in array
compArray(1) = "asdf"
'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"
'Prints "ErrorState"
Debug.Print Computers("Computer Name")
Collections cannot be sorted so if you need to sort data you will probably want to use an array.

Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!
Edit:
Sub ArrayExample()
Dim subject As String
Dim TestArray() As String
Dim counter As Long
subject = "Example"
counter = Len(subject)
ReDim TestArray(1 To counter) As String
For counter = 1 To Len(subject)
TestArray(counter) = Right(Left(subject, counter), 1)
Next
End Sub
You can change time() to now() for it to work
from datetime import datetime, timedelta
datetime.now() + timedelta(hours=1)
this works with "NA"
not for NA
comments = c("no","yes","NA")
for (l in 1:length(comments)) {
#if (!is.na(comments[l])) print(comments[l])
if (comments[l] != "NA") print(comments[l])
}
strtotime
to convert the string to a time stampeg:
$time = strtotime($myInput);
$newTime = $time + 86400;
If it's only adding 1 day, then using strtotime again is probably overkill.
Another way to look at it is to consider git rebase master
as:
Rebase the current branch on top of
master
Here , 'master
' is the upstream branch, and that explain why, during a rebase, ours
and theirs
are reversed.
Try:
while [ $stats -gt 300 -o $stats -eq 0 ]

function getParsedDate(date){
date = String(date).split(' ');
var days = String(date[0]).split('-');
var hours = String(date[1]).split(':');
return [parseInt(days[0]), parseInt(days[1])-1, parseInt(days[2]), parseInt(hours[0]), parseInt(hours[1]), parseInt(hours[2])];
}
var date = new Date(...getParsedDate('2016-01-04 10:34:23'));
console.log(date);
Because of the variances in parsing of date strings, it is recommended to always manually parse strings as results are inconsistent, especially across different ECMAScript implementations where strings like "2015-10-12 12:00:00" may be parsed to as NaN, UTC or local timezone.

On the other hand, referring to a different blogging Scott (Watermasyck, of Telligent) - they found that most users could speed up the websites (using Telligent's Community Server), by putting the database on the same machine as the web site. However, in their customer's case, usually the db & web server are the only applications on that machine, and the website isn't straining the machine that much. Then, the efficiency of not having to send data across the network more that made up for the increased strain.
If this is for an intranet application and all of the clients use DHCP, you can query the DHCP server for the MAC address for a given IP address.
From my experience, once you include the chartjs-plugin-datalabels plugin (make sure to place the <script>
tag after the chart.js tag on your page), your charts begin to display values.
If you then choose you can customize it to fit your needs. The customization is clearly documented here but basically, the format is like this hypothetical example:
var myBarChart = new Chart(ctx, {
type: 'bar',
data: yourDataObject,
options: {
// other options
plugins: {
datalabels: {
anchor :'end',
align :'top',
// and if you need to format how the value is displayed...
formatter: function(value, context) {
return GetValueFormatted(value);
}
}
}
}
});
the problem is because you have got the query over multiple lines using the " " that PHP is actually sending all the white spaces in to MySQL which is causing it to error out.
Either put it on one line or append on each line :o)
Sqlyog must be trimming white spaces on each line which explains why its working.
Example:
$qr2="INSERT INTO wp_bp_activity
(
user_id,
(this stuff)component,
(is) `type`,
(a) `action`,
(problem) content,
primary_link,
item_id,....
Use geom_boxplot(outlier.shape = NA)
to not display the outliers and scale_y_continuous(limits = c(lower, upper))
to change the axis limits.
An example.
n <- 1e4L
dfr <- data.frame(
y = exp(rlnorm(n)), #really right-skewed variable
f = gl(2, n / 2)
)
p <- ggplot(dfr, aes(f, y)) +
geom_boxplot()
p # big outlier causes quartiles to look too slim
p2 <- ggplot(dfr, aes(f, y)) +
geom_boxplot(outlier.shape = NA) +
scale_y_continuous(limits = quantile(dfr$y, c(0.1, 0.9)))
p2 # no outliers plotted, range shifted
Actually, as Ramnath showed in his answer (and Andrie too in the comments), it makes more sense to crop the scales after you calculate the statistic, via coord_cartesian
.
coord_cartesian(ylim = quantile(dfr$y, c(0.1, 0.9)))
(You'll probably still need to use scale_y_continuous
to fix the axis breaks.)
In the System.Windows.Forms
class, you can find more on the MSDN page for this here. Among other things you can control the message box text, title, default button, and icons. Since you didn't specify, if you are trying to do this in a webpage you should look at triggering the javascript alert("my message");
or confirm("my question");
functions.
var str = "0000000...0000";
var arr = str.split("");
usage in expressions: arr[i]*1;
EDIT: if arr
supposed to be used in integer expressions, then please don't mind the char value of '0'. You just use it as follows: a = a * arr[i]
(assuming a
has integer value).
See if these helps :-
Guid.Parse
- DocsGuid guidResult = Guid.Parse(inputString)
Guid.TryParse
- Docsbool isValid = Guid.TryParse(inputString, out guidOutput)
As a tangential note, one case where the ability to have multiple .gitignore
files is very useful is if you want an extra directory in your working copy that you never intend to commit. Just put a 1-byte .gitignore
(containing just a single asterisk) in that directory and it will never show up in git status
etc.
You need to overload operator <<
for mystruct
class
Something like :-
friend ostream& operator << (ostream& os, const mystruct& m)
{
os << m.m_a <<" " << m.m_b << endl;
return os ;
}

Unless google serves this image with the correct Access-Control-Allow-Origin
header, then you wont be able to use their image in canvas. This is due to not having CORS
approval. You can read more about this here, but it essentially means:
Although you can use images without CORS approval in your canvas, doing so taints the canvas. Once a canvas has been tainted, you can no longer pull data back out of the canvas. For example, you can no longer use the canvas toBlob(), toDataURL(), or getImageData() methods; doing so will throw a security error.
This protects users from having private data exposed by using images to pull information from remote web sites without permission.
I suggest just passing the URL to your server-side language and using curl to download the image. Be careful to sanitise this though!
EDIT:
As this answer is still the accepted answer, you should check out @shadyshrif's answer, which is to use:
var img = new Image();
img.setAttribute('crossOrigin', 'anonymous');
img.src = url;
This will only work if you have the correct permissions, but will at least allow you to do what you want.

If the constructor of a class is private then you cannot create an object for class from outside of it.
class Test{
int x, y;
private Test(){
.......
.......
}
}
We cannot create an object for above class from outside of it. So you cannot access x, y from outside of the class. Then what is the use of this class?
Here is the Answer : FACTORY method.
Add the below method in above class
public static Test getObject(){
return new Test();
}
So now you can create an object for this class from outside of it. Like the way...
Test t = Test.getObject();
Hence, a static method which returns the object of the class by executing its private constructor is called as FACTORY method
.
Be sure there is nothing on your button (such a div or a trasparent img) that keeps from clicking the button. It sounds stupid, but sometimes we think that jQuery is not working and all that stuffs and the problem is on the positioning of DOM elements.
