I think your problems are due to your test structure. I've found it difficult to mix mocking with the traditional method of implementing interfaces in the test class (as you've done here).
If you implement the listener as a Mock you can then verify the interaction.
Listener listener = mock(Listener.class);
w.addListener(listener);
world.doAction(..);
verify(listener).doAction();
This should satisfy you that the 'World' is doing the right thing.
Try putting single quotes around the data source:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source='D:\ptdb\Program Tracking Database.mdb';
The problem tends to be white space which does have meaning to the parser.
If you had other attributes (e.g., Extended Properties), their values may also have to be enclosed in single quotes:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source='D:\ptdb\Program Tracking Database.mdb'; Extended Properties='Excel 8.0;HDR=YES;IMEX=1;';
You could equally well use double quotes; however, you'll probably have to escape them, and I find that more of a Pain In The Algorithm than using singles.
In order to use the legacy UIApplication method to hide/show the status bar, your app must set a plist value for iOS 7:
View-Controller Based Status Bar Appearance = NO
This value is set to YES by default. If you change it to NO, you can use the legacy methods. If you leave it set to YES, you can still hide the status bar, but it's up to each view controller subclass in your app to override: prefersStatusBarHidden
to return YES.
Any time your app needs the status bar appearance or visibility to change, and View-Controller Based Status Bar Appearance is set to YES, your outermost view controller needs to call:
setNeedsStatusBarAppearanceUpdateAnimation

import requests
request = requests.get(value)
if request.status_code == 200:
return True
return False
# Using httplib2.
import httplib2
try:
http = httplib2.Http()

If using Ansible, you can use the fetch_url function:
from ansible.module_utils.basic import AnsibleModule
from ansible.module_utils.urls import fetch_url
module = AnsibleModule(
dict(),
supports_check_mode=True)
try:
response, info = fetch_url(module, url)
if info['status'] == 200:
return True
except Exception:
pass
return False
You can set your test properties in src/test/resources/config/application.yml
file. Spring Boot test cases will take properties from application.yml
file in test directory.
The config
folder is predefined in Spring Boot.
As per documentation:
If you do not like application.properties as the configuration file name, you can switch to another file name by specifying a spring.config.name environment property. You can also refer to an explicit location by using the spring.config.location environment property (which is a comma-separated list of directory locations or file paths). The following example shows how to specify a different file name:
java -jar myproject.jar --spring.config.location=classpath:/default.properties,classpath:/override.properties
The same works for application.yml
Documentation:
For using dictionary object in typescript you can use interface as below:
interface Dictionary<T> {
[Key: string]: T;
}
and, use this for your class property type.
export class SearchParameters {
SearchFor: Dictionary<string> = {};
}
to use and initialize this class,
getUsers(): Observable<any> {
var searchParams = new SearchParameters();
searchParams.SearchFor['userId'] = '1';
searchParams.SearchFor['userName'] = 'xyz';
return this.http.post(searchParams, 'users/search')
.map(res => {
return res;
})
.catch(this.handleError.bind(this));
}
You're looking for the indexOf function:
if (str.indexOf("are") >= 0){//Do stuff}
The easiest thing is to run the program, open the task manager, right-click the process and select properties, here is the full address
You can try this:
$ mysql -u root -p
> grant all privileges on *.* to `root`@`%` identified by 'password';
> flush privileges;
This is extreme, but I built a dynamic, database-driven filter using a 2 column database table named FILE_TYPES, with field names EXTENSION and DOCTYPE:
---------------------------------
| EXTENSION | DOCTYPE |
---------------------------------
| .doc | Document |
| .docx | Document |
| .pdf | Document |
| ... | ... |
| .bmp | Image |
| .jpg | Image |
| ... | ... |
---------------------------------
Obviously I had many different types and extensions, but I'm simplifying it for this example. Here is my function:
private static string GetUploadFilter()
{
// Desired format:
// "Document files (*.doc, *.docx, *.pdf)|*.doc;*.docx;*.pdf|"
// "Image files (*.bmp, *.jpg)|*.bmp;*.jpg|"
string filter = String.Empty;
string nameFilter = String.Empty;
string extFilter = String.Empty;
// Used to get extensions
DataTable dt = new DataTable();
dt = DataLayer.Get_DataTable("SELECT * FROM FILE_TYPES ORDER BY EXTENSION");
// Used to cycle through doctype groupings ("Images", "Documents", etc.)
DataTable dtDocTypes = new DataTable();
dtDocTypes = DataLayer.Get_DataTable("SELECT DISTINCT DOCTYPE FROM FILE_TYPES ORDER BY DOCTYPE");
// For each doctype grouping...
foreach (DataRow drDocType in dtDocTypes.Rows)
{
nameFilter = drDocType["DOCTYPE"].ToString() + " files (";
// ... add its associated extensions
foreach (DataRow dr in dt.Rows)
{
if (dr["DOCTYPE"].ToString() == drDocType["DOCTYPE"].ToString())
{
nameFilter += "*" + dr["EXTENSION"].ToString() + ", ";
extFilter += "*" + dr["EXTENSION"].ToString() + ";";
}
}
// Remove endings put in place in case there was another to add, and end them with pipe characters:
nameFilter = nameFilter.TrimEnd(' ').TrimEnd(',');
nameFilter += ")|";
extFilter = extFilter.TrimEnd(';');
extFilter += "|";
// Add the name and its extensions to our main filter
filter += nameFilter + extFilter;
extFilter = ""; // clear it for next round; nameFilter will be reset to the next DOCTYPE on next pass
}
filter = filter.TrimEnd('|');
return filter;
}
private void UploadFile(string fileType, object sender)
{
Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();
string filter = GetUploadFilter();
dlg.Filter = filter;
if (dlg.ShowDialog().Value == true)
{
string fileName = dlg.FileName;
System.IO.FileStream fs = System.IO.File.OpenRead(fileName);
byte[] array = new byte[fs.Length];
// This will give you just the filename
fileName = fileName.Split('\\')[fileName.Split('\\').Length - 1];
...
Should yield a filter that looks like this:
To expand on the answer from 'levi' and to show how to get the response from the upload so you can process the file upload:
selectFile(event) {
event.preventDefault();
file_input = document.createElement('input');
file_input.addEventListener("change", uploadFile, false);
file_input.type = 'file';
file_input.click();
},
uploadFile() {
let dataArray = new FormData();
dataArray.append('file', file_input.files[0]);
// Obviously, you can substitute with JQuery or whatever
axios.post('/your_super_special_url', dataArray).then(function() {
//
});
}
A sample command that exhibits the symptom: sed 's/./@/' <<<$'\xfc'
fails, because byte 0xfc
is not a valid UTF-8 char.
Note that, by contrast, GNU sed
(Linux, but also installable on macOS) simply passes the invalid byte through, without reporting an error.
Using the formerly accepted answer is an option if you don't mind losing support for your true locale (if you're on a US system and you never need to deal with foreign characters, that may be fine.)
However, the same effect can be had ad-hoc for a single command only:
LC_ALL=C sed -i "" 's|"iphoneos-cross","llvm-gcc:-O3|"iphoneos-cross","clang:-Os|g' Configure
Note: What matters is an effective LC_CTYPE
setting of C
, so LC_CTYPE=C sed ...
would normally also work, but if LC_ALL
happens to be set (to something other than C
), it will override individual LC_*
-category variables such as LC_CTYPE
. Thus, the most robust approach is to set LC_ALL
.
However, (effectively) setting LC_CTYPE
to C
treats strings as if each byte were its own character (no interpretation based on encoding rules is performed), with no regard for the - multibyte-on-demand - UTF-8 encoding that OS X employs by default, where foreign characters have multibyte encodings.
In a nutshell: setting LC_CTYPE
to C
causes the shell and utilities to only recognize basic English letters as letters (the ones in the 7-bit ASCII range), so that foreign chars. will not be treated as letters, causing, for instance, upper-/lowercase conversions to fail.
Again, this may be fine if you needn't match multibyte-encoded characters such as é
, and simply want to pass such characters through.
If this is insufficient and/or you want to understand the cause of the original error (including determining what input bytes caused the problem) and perform encoding conversions on demand, read on below.
The problem is that the input file's encoding does not match the shell's.
More specifically, the input file contains characters encoded in a way that is not valid in UTF-8 (as @Klas Lindbäck stated in a comment) - that's what the sed
error message is trying to say by invalid byte sequence
.
Most likely, your input file uses a single-byte 8-bit encoding such as ISO-8859-1
, frequently used to encode "Western European" languages.
Example:
The accented letter à
has Unicode codepoint 0xE0
(224) - the same as in ISO-8859-1
. However, due to the nature of UTF-8 encoding, this single codepoint is represented as 2 bytes - 0xC3 0xA0
, whereas trying to pass the single byte 0xE0
is invalid under UTF-8.
Here's a demonstration of the problem using the string voilà
encoded as ISO-8859-1
, with the à
represented as one byte (via an ANSI-C-quoted bash string ($'...'
) that uses \x{e0}
to create the byte):
Note that the sed
command is effectively a no-op that simply passes the input through, but we need it to provoke the error:
# -> 'illegal byte sequence': byte 0xE0 is not a valid char.
sed 's/.*/&/' <<<$'voil\x{e0}'
To simply ignore the problem, the above LCTYPE=C
approach can be used:
# No error, bytes are passed through ('á' will render as '?', though).
LC_CTYPE=C sed 's/.*/&/' <<<$'voil\x{e0}'
If you want to determine which parts of the input cause the problem, try the following:
# Convert bytes in the 8-bit range (high bit set) to hex. representation.
# -> 'voil\x{e0}'
iconv -f ASCII --byte-subst='\x{%02x}' <<<$'voil\x{e0}'
The output will show you all bytes that have the high bit set (bytes that exceed the 7-bit ASCII range) in hexadecimal form. (Note, however, that that also includes correctly encoded UTF-8 multibyte sequences - a more sophisticated approach would be needed to specifically identify invalid-in-UTF-8 bytes.)
Performing encoding conversions on demand:
Standard utility iconv
can be used to convert to (-t
) and/or from (-f
) encodings; iconv -l
lists all supported ones.
Examples:
Convert FROM ISO-8859-1
to the encoding in effect in the shell (based on LC_CTYPE
, which is UTF-8
-based by default), building on the above example:
# Converts to UTF-8; output renders correctly as 'voilà'
sed 's/.*/&/' <<<"$(iconv -f ISO-8859-1 <<<$'voil\x{e0}')"
Note that this conversion allows you to properly match foreign characters:
# Correctly matches 'à' and replaces it with 'ü': -> 'voilü'
sed 's/à/ü/' <<<"$(iconv -f ISO-8859-1 <<<$'voil\x{e0}')"
To convert the input BACK to ISO-8859-1
after processing, simply pipe the result to another iconv
command:
sed 's/à/ü/' <<<"$(iconv -f ISO-8859-1 <<<$'voil\x{e0}')" | iconv -t ISO-8859-1
The easiest method would be to wrap them both in a container div
and apply margin: 0 auto;
to the container. This will center both the #page-wrap
and the #sidebar
divs on the page. However, if you want that off-center look, you could then shift the container
200px
to the left, to account for the width of the #sidebar
div.

Your local branch doensn't know about the remote branch. If you don't tell git that your local branch (master) is supposed to compare itself to the remote counterpart (origin/master in this case); then git status won't tell you the difference between your branch and the remote one. So you should use:
git branch --set-upstream-to origin/master
or with the short option:
git branch -u origin/master
This options --set-upstream-to (or -u in short) was introduced in git 1.8.0.
Once you have set this option; git status
will show you something like:
# Your branch is ahead of 'origin/master' by 1 commit.
Your assignments are all nested within your conditional if blocks which means that there is potential for them to never be assigned.
At the top of your class, initialise them to 0 or some other value
For dropdown options you probably want something like this:
var conceptName = $('#aioConceptName').find(":selected").text();
The reason val()
doesn't do the trick is because clicking an option doesn't change the value of the dropdown--it just adds the :selected
property to the selected option which is a child of the dropdown.
To open docs automatically in Chrome without them being saved;
Go to the the three vertical dots on your top far right corner in Chrome.
Scroll down to Settings and click.
Scroll down to Show advance settings...
Scroll down to Downloads under Download location: click the Change button and chose tmp folder. Then just close the screen.
Click on any attachments and a small box to the left will appear, it should automatically open if you click on it.
When the bottom left box appears it will contain an arrow; click on it and choose the option "Always open files of this type". Going forward it will open the file instantly instead of the small box appearing to the left and you having to click on it to open. You will have to do it just once for various files such PDF, Excel 2010, Excel 2013 Word, ect.
The best way is to use menu mnemonics, i.e. to have menu entries in your main form that get assigned the keyboard shortcut you want. Then everything else is handled internally and all you have to do is to implement the appropriate action that gets executed in the Click
event handler of that menu entry.
In C, int
, char
, long
, etc. are all integers.
They typically have different memory sizes and thus different ranges as in INT_MIN
to INT_MAX
. char
and arrays of char
are often used to store characters and strings. Integers are stored in many types: int
being the most popular for a balance of speed, size and range.
ASCII is by far the most popular character encoding, but others exist. The ASCII code for an 'A' is 65, 'a' is 97, '\n' is 10, etc. ASCII data is most often stored in a char
variable. If the C environment is using ASCII encoding, the following all store the same value into the integer variable.
int i1 = 'a';
int i2 = 97;
char c1 = 'a';
char c2 = 97;
To convert an int
to a char
, simple assign:
int i3 = 'b';
int i4 = i3;
char c3;
char c4;
c3 = i3;
// To avoid a potential compiler warning, use a cast `char`.
c4 = (char) i4;
This warning comes up because int
typically has a greater range than char
and so some loss-of-information may occur. By using the cast (char)
, the potential loss of info is explicitly directed.
To print the value of an integer:
printf("<%c>\n", c3); // prints <b>
// Printing a `char` as an integer is less common but do-able
printf("<%d>\n", c3); // prints <98>
// Printing an `int` as a character is less common but do-able.
// The value is converted to an `unsigned char` and then printed.
printf("<%c>\n", i3); // prints <b>
printf("<%d>\n", i3); // prints <98>
There are additional issues about printing such as using %hhu
or casting when printing an unsigned char
, but leave that for later. There is a lot to printf()
.
Jquery easing plugin renamed their effect function names from version 1.2 on. If you have some javascript depending on easing and it is not calling the right effect name it will throw this error.
It because every time
void pthread_exit(void *ret);
will be called from thread function so which ever you want to return simply its pointer pass with pthread_exit().
Now at
int pthread_join(pthread_t tid, void **ret);
will be always called from where thread is created so here to accept that returned pointer you need double pointer ..
i think this code will help you to understand this
#include <stdio.h>
#include <string.h>
#include <pthread.h>
#include <stdlib.h>
void* thread_function(void *ignoredInThisExample)
{
char *a = malloc(10);
strcpy(a,"hello world");
pthread_exit((void*)a);
}
int main()
{
pthread_t thread_id;
char *b;
pthread_create (&thread_id, NULL,&thread_function, NULL);
pthread_join(thread_id,(void**)&b); //here we are reciving one pointer
value so to use that we need double pointer
printf("b is %s\n",b);
free(b); // lets free the memory
}
Your Call works if it were a Table Valued Function. Since its a scalar function, you need to call it like:
SELECT dbo.fn_HomePageSlider(9, 3025) AS MyResult
On my windows 8.1 machine default VS Code font is Consolas, but you can easily change the font in File->Preferences->User Preferences. setting.json file will be opened alongside with default settings file, from where you can take syntax and names for settings properties and set your own ones in settings.json.
The Host
Header tells the webserver which virtual host to use (if set up). You can even have the same virtual host using several aliases (= domains and wildcard-domains). In this case, you still have the possibility to read that header manually in your web app if you want to provide different behavior based on different domains addressed. This is possible because in your webserver you can (and if I'm not mistaken you must) set up one vhost to be the default host. This default vhost is used whenever the host
header does not match any of the configured virtual hosts.
That means: You get it right, although saying "multiple hosts" may be somewhat misleading: The host (the addressed machine) is the same, what really gets resolved to the IP address are different domain names (including subdomains) that are also referred to as hostnames (but not hosts!).
Although not part of the question, a fun fact: This specification led to problems with SSL in early days because the web server has to deliver the certificate that corresponds to the domain the client has addressed. However, in order to know what certificate to use, the webserver should have known the addressed hostname in advance. But because the client sends that information only over the encrypted channel (which means: after the certificate has already been sent), the server had to assume you browsed the default host. That meant one ssl-secured domain per IP address / port-combination.
This has been overcome with Server Name Indication; however, that again breaks some privacy, as the server name is now transferred in plain text again, so every man-in-the-middle would see which hostname you are trying to connect to.
Although the webserver would know the hostname from Server Name Indication, the Host
header is not obsolete, because the Server Name Indication information is only used within the TLS handshake. With an unsecured connection, there is no Server Name Indication at all, so the Host
header is still valid (and necessary).
Another fun fact: Most webservers (if not all) reject your HTTP request if it does not contain exactly one Host
header, even if it could be omitted because there is only the default vhost configured. That means the minimum required information in an http-(get-)request is the first line containing METHOD
RESOURCE
and PROTOCOL VERSION
and at least the Host
header, like this:
GET /someresource.html HTTP/1.1
Host: www.example.com
In the MDN Documentation on the "Host" header they actually phrase it like this:
A Host header field must be sent in all HTTP/1.1 request messages. A 400 (Bad Request) status code will be sent to any HTTP/1.1 request message that lacks a Host header field or contains more than one.
As mentioned by Darrel Miller, the complete specs can be found in RFC7230.
To get uppercase letters in addition to lower case letters, you could also do the following:
String alphabetWithUpper = "abcdefghijklmnopqrstuvwxyz" + "abcdefghijklmnopqrstuvwxyz".toUpperCase();
char[] letters = alphabetWithUpper.toCharArray();
take a look at shutil
. shutil.copyfile(src, dst)
will copy a file to another file.
Note that shutil.copyfile
will not create directories that do not already exist. for that, use os.makedirs
The solutions above using structuring do suffer from the fact that you have an used variable, which might cause complaints from ESLint if you're using that.
So here are my solutions:
const src = { a: 1, b: 2 }
const result = Object.keys(src)
.reduce((acc, k) => k === 'b' ? acc : { ...acc, [k]: src[k] }, {})
On most platforms (except IE unless using Babel), you could also do:
const src = { a: 1, b: 2 }
const result = Object.fromEntries(
Object.entries(src).filter(k => k !== 'b'))
Have a look at the following apache commons function:
org.apache.commons.io.FileUtils.readFileToByteArray(File)
Difference between Spring, Struts and Hibernate are following:
If checked:
$( "SELECTOR" ).attr( "checked" ) // Returns ‘true’ if present on the element, returns undefined if not present
$( "SELECTOR" ).prop( "checked" ) // Returns true if checked, false if unchecked.
$( "SELECTOR" ).is( ":checked" ) // Returns true if checked, false if unchecked.
Get the checked val:
$( "SELECTOR:checked" ).val()
Get the checked val numbers:
$( "SELECTOR:checked" ).length
Check or uncheck checkbox
$( "SELECTOR" ).prop( "disabled", false );
$( "SELECTOR" ).prop( "checked", true );
Edit 2014/01: improved example usage to include the nonVideoLayout, videoLayout, and videoLoading views, for those users requesting more example code for better understading.
Edit 2013/12: some bug fixes related to Sony Xperia devices compatibility, but which in fact affected all devices.
Edit 2013/11: after the release of Android 4.4 KitKat (API level 19) with its new Chromium webview, I had to work hard again. Several improvements were made. You should update to this new version. I release this source under WTFPL.
Edit 2013/04: after 1 week of hard work, I finally have achieved everything I needed. I think this two generic classes that I have created can solve all you problems.

As has been pointed out, the objects are created base-down upon construction. When the base object is being constructed, the derived object does not exist yet, so a virtual function override cannot work.
However, this can be solved with polymorphic getters that use static polymorphism instead of virtual functions if your getters return constants, or otherwise can be expressed in a static member function, This example uses CRTP (https://en.wikipedia.org/wiki/Curiously_recurring_template_pattern).
template<typename DerivedClass>
class Base
{
public:
inline Base() :
foo(DerivedClass::getFoo())
{}
inline int fooSq() {
return foo * foo;
}
const int foo;
};
class A : public Base<A>
{
public:
inline static int getFoo() { return 1; }
};
class B : public Base<B>
{
public:
inline static int getFoo() { return 2; }
};
class C : public Base<C>
{
public:
inline static int getFoo() { return 3; }
};
int main()
{
A a;
B b;
C c;
std::cout << a.fooSq() << ", " << b.fooSq() << ", " << c.fooSq() << std::endl;
return 0;
}
With the use of static polymorphism, the base class knows which class' getter to call as the information is provided at compile-time.
I couldn't find a way to do it completely recursive (without any auxiliary data-structure). But if the queue Q is passed by reference, then you can have the following silly tail recursive function:
BFS(Q)
{
if (|Q| > 0)
v <- Dequeue(Q)
Traverse(v)
foreach w in children(v)
Enqueue(Q, w)
BFS(Q)
}
To convert a valid JSON string back, you can use the json_decode()
method.
To convert it back to an object use this method:
$jObj = json_decode($jsonString);
And to convert it to a associative array, set the second parameter to true
:
$jArr = json_decode($jsonString, true);
By the way to convert your mentioned string back to either of those, you should have a valid JSON string. To achieve it, you should do the following:
Coords
array, remove the two "
(double quote marks) from the start and end of the object.,
), so add commas between the objects in the Coords
array..And you will have a valid JSON String..
Here is your JSON String I converted to a valid one: http://pastebin.com/R16NVerw
Box Selecting
Windows & Linux: Shift + Alt + 'Mouse Left Button'
macOS: Shift + option + 'Click'
Esc to exit selection.
MacOS: Shift + Alt/Option + Command + 'arrow key'
I have found the solution else where:
SELECT SUBSTRING(master.dbo.fn_varbintohexstr(HashBytes('MD5', 'HelloWorld')), 3, 32)
I just used the javascript console in Chrome to do this. I replaced some of your stuff with placeholders.
var temp= ['one', 'two', 'three']; //'${temp}';
//alert(options);
var $select = $('<select>'); //$('#down');
$select.find('option').remove();
$.each(temp, function(key, value) {
$('<option>').val(key).text(value).appendTo($select);
});
console.log($select.html());
Output:
<option value="0">one</option><option value="1">two</option><option value="2">three</option>
However it looks like your json is probably actually a string because the following will end up doing what you describe. So make your JSON actual JSON not a string.
var temp= "['one', 'two', 'three']"; //'${temp}';
//alert(options);
var $select = $('<select>'); //$('#down');
$select.find('option').remove();
$.each(temp, function(key, value) {
$('<option>').val(key).text(value).appendTo($select);
});
console.log($select.html());
By using the constraint definition on table creation, you can specify one or multiple constraints that span multiple columns. The syntax, simplified from technet's documentation, is in the form of:
CONSTRAINT constraint_name UNIQUE [ CLUSTERED | NONCLUSTERED ]
(
column [ ASC | DESC ] [ ,...n ]
)
Therefore, the resuting table definition would be:
CREATE TABLE [dbo].[user](
[userID] [int] IDENTITY(1,1) NOT NULL,
[fcode] [int] NULL,
[scode] [int] NULL,
[dcode] [int] NULL,
[name] [nvarchar](50) NULL,
[address] [nvarchar](50) NULL,
CONSTRAINT [PK_user_1] PRIMARY KEY CLUSTERED
(
[userID] ASC
),
CONSTRAINT [UQ_codes] UNIQUE NONCLUSTERED
(
[fcode], [scode], [dcode]
)
) ON [PRIMARY]
The first answer covers it.
Im guessing that somewhere down the line you may decide to store your info in a different class/structure. In that case you probably wouldn't want the results going in to an array from the split() method.
You didn't ask for it, but I'm bored, so here is an example, hope it's helpful.
This might be the class you write to represent a single person:
class Person {
public String firstName;
public String lastName;
public int id;
public int age;
public Person(String firstName, String lastName, int id, int age) {
this.firstName = firstName;
this.lastName = lastName;
this.id = id;
this.age = age;
}
// Add 'get' and 'set' method if you want to make the attributes private rather than public.
}
Then, the version of the parsing code you originally posted would look something like this: (This stores them in a LinkedList, you could use something else like a Hashtable, etc..)
try
{
String ruta="entrada.al";
BufferedReader reader = new BufferedReader(new FileReader(ruta));
LinkedList<Person> list = new LinkedList<Person>();
String line = null;
while ((line=reader.readLine())!=null)
{
if (!(line.equals("%")))
{
StringTokenizer st = new StringTokenizer(line, "*");
if (st.countTokens() == 4)
list.add(new Person(st.nextToken(), st.nextToken(), Integer.parseInt(st.nextToken()), Integer.parseInt(st.nextToken)));
else
// whatever you want to do to account for an invalid entry
// in your file. (not 4 '*' delimiters on a line). Or you
// could write the 'if' clause differently to account for it
}
}
reader.close();
}
The quick and dirty solution is to explicitly cast to any
(y as any).x
The "advantage" is that, the cast being explicit, this will compile even with the noImplicitAny
flag set.
The proper solution is to update the typings definition file.
Please note that, when you cast a variable to any
, you opt out of type checking for that variable.
Since I am in disclaimer mode, double casting via any
combined with a new interface, can be useful in situations where you
yet, you still want some form of typing.
Say you want to patch the definition of an instance of y
of type OrginalDef
with a new property x
of type number
:
const y: OriginalDef = ...
interface DefWithNewProperties extends OriginalDef {
x: number
}
const patched = y as any as DefWithNewProperties
patched.x = .... //will compile
List<Long> actual = Arrays.asList(1L, 2L);
List<Long> expected = Arrays.asList(2L, 1L);
assertThat(actual, containsInAnyOrder(expected.toArray()));
Shorter version of @Joe's answer without redundant parameters.
If you're looking for a particular string, put quotes around it:
awk '$1 == "findtext" {print $3}'
Otherwise, awk will assume it's a variable name.

Tested and works in Safari 5 and IE6+.
You're right that it involves a loop, but this is, at least, made simple by use of the each()
method:
$('.target').each(
function(){
// iterate through each of the `.target` elements, and do stuff in here
// `this` and `$(this)` refer to the current `.target` element
var images = $(this).find('img'),
imageWidth = images.width(); // returns the width of the _first_ image
numImages = images.length;
$(this).css('width', (imageWidth*numImages));
});
References:
A better approach from the correct solution here in order to not alter target:
function extend(){
let sources = [].slice.call(arguments, 0), result = {};
sources.forEach(function (source) {
for (let prop in source) {
result[prop] = source[prop];
}
});
return result;
}

Setting isBodyHtml
to true
allows you to use HTML tags in the message body:
msg = new MailMessage("[email protected]",
"[email protected]", "Message from PSSP System",
"This email sent by the PSSP system<br />" +
"<b>this is bold text!</b>");
msg.IsBodyHtml = true;
var str = 'asd-0.testing';
var regex = /(asd-)\d(\.\w+)/;
str = str.replace(regex, "$11$2");
console.log(str);
Or if you're sure there won't be any other digits in the string:
var str = 'asd-0.testing';
var regex = /\d/;
str = str.replace(regex, "1");
console.log(str);
Deep copy literally performs a deep copy. It means, that if your class has some fields that are references, their values will be copied, not references themselves. If, for example you have two instances of a class, A & B with fields of reference type, and perform a deep copy, changing a value of that field in A won't affect a value in B. And vise-versa. Things are different with shallow copy, because only references are copied, therefore, changing this field in a copied object would affect the original object.
What type of a copy does a copy constructor does?
It is implementation - dependent. This means that there are no strict rules about that, you can implement it like a deep copy or shallow copy, however as far as i know it is a common practice to implement a deep copy in a copy constructor. A default copy constructor performs a shallow copy though.
if you replace in the function SimpleDateFormat("hh") with ("HH") will format the hour in 24 hours instead of 12.
SimpleDateFormat df = new SimpleDateFormat("HH:mm");
IEnumerable<DateTime?> _getCurrentHolidayList; //this will not initailize
Assign value(_getCurrentHolidayList) inside the loop
foreach (HolidaySummaryList _holidayItem in _holidayDetailsList)
{
if (_holidayItem.CountryId == Countryid)
_getCurrentHolidayList = _holidayItem.Holiday;
}
After your are passing the local varibale to another method like below. It throw error(use of unassigned variable). eventhough nullable mentioned in time of decalration.
var cancelRescheduleCondition = GetHolidayDays(_item.ServiceDateFrom, _getCurrentHolidayList);
if you mentioned like below, It will not throw any error.
IEnumerable<DateTime?> _getCurrentHolidayList =null;
This should be working too using JPA 2.0 @MapsId annotation instead of Hibernate's GenericGenerator:
@Entity
public class Person {
@Id
@GeneratedValue
public int id;
@OneToOne
@PrimaryKeyJoinColumn
public OtherInfo otherInfo;
rest of attributes ...
}
@Entity
public class OtherInfo {
@Id
public int id;
@MapsId
@OneToOne
@JoinColumn(name="id")
public Person person;
rest of attributes ...
}
More details on this in Hibernate 4.1 documentation under section 5.1.2.2.7.
if you have scenario in which you have to remove more then one values from the foreach array in this case you have to pass value by reference in for each: I try to explain this scenario:
foreach ($manSkuQty as $man_sku => &$man_qty) {
foreach ($manufacturerSkus as $key1 => $val1) {
// some processing here and unset first loops entries
// here dont include again for next iterations
if(some condition)
unset($manSkuQty[$key1]);
}
}
}
in second loop you want to unset first loops entries dont come again in the iteration for performance purpose or else then unset from memory as well because in memory they present and will come in iterations.
Use JOIN to join the subqueries and use ON to say where the rows from each subquery must match:
SELECT T1.col_a, T1.col_b, T2.col_c
FROM (SELECT col_a, col_b, ...etc...) AS T1
JOIN (SELECT col_a, col_c, ...etc...) AS T2
ON T1.col_a = T2.col_a
If there are some values of col_a that are in T1 but not in T2, you can use a LEFT OUTER JOIN instead.
First enable mod_headers
on your server, then you can use header directive in both Apache conf and .htaccess
.
mod_headers
a2enmod headers
.htaccess
fileHeader add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"
If you remove directives attribute it should work.
@Component({
selector: 'parent',
template: `
<h1>Parent Component</h1>
<child></child>
`
})
export class ParentComponent{}
@Component({
selector: 'child',
template: `
<h4>Child Component</h4>
`
})
export class ChildComponent{}
Directives are like components but they are used in attributes. They also have a declarator @Directive
. You can read more about directives Structural Directives and Attribute Directives.
There are two other kinds of Angular directives, described extensively elsewhere: (1) components and (2) attribute directives.
A component manages a region of HTML in the manner of a native HTML element. Technically it's a directive with a template.
Also if you are open the glossary you can find that components are also directives.
Directives fall into one of the following categories:
Components combine application logic with an HTML template to render application views. Components are usually represented as HTML elements. They are the building blocks of an Angular application.
Attribute directives can listen to and modify the behavior of other HTML elements, attributes, properties, and components. They are usually represented as HTML attributes, hence the name.
Structural directives are responsible for shaping or reshaping HTML layout, typically by adding, removing, or manipulating elements and their children.
The difference that components have a template. See Angular Architecture overview.
A directive is a class with a
@Directive
decorator. A component is a directive-with-a-template; a@Component
decorator is actually a@Directive
decorator extended with template-oriented features.
The @Component
metadata doesn't have directives
attribute. See Component decorator.
dynamic_cast should do the trick
TYPE& dynamic_cast<TYPE&> (object);
TYPE* dynamic_cast<TYPE*> (object);
The dynamic_cast
keyword casts a datum from one pointer or reference type to another, performing a runtime check to ensure the validity of the cast.
If you attempt to cast to pointer to a type that is not a type of actual object, the result of the cast will be NULL. If you attempt to cast to reference to a type that is not a type of actual object, the cast will throw a bad_cast
exception.
Make sure there is at least one virtual function in Base class to make dynamic_cast work.
Wikipedia topic Run-time type information
RTTI is available only for classes that are polymorphic, which means they have at least one virtual method. In practice, this is not a limitation because base classes must have a virtual destructor to allow objects of derived classes to perform proper cleanup if they are deleted from a base pointer.
The problem is that buttonClickedEvent
is a member function and you need a pointer to member in order to invoke it.
Try this:
void (MyClass::*func)(int);
func = &MyClass::buttonClickedEvent;
And then when you invoke it, you need an object of type MyClass
to do so, for example this
:
(this->*func)(<argument>);

In addition to the answer by fenix2222 (which worked for me) I had to modify the last line to:
config.Save(ConfigurationSaveMode.Modified);
Without this, the new value was still being written to the config file but the old value was retrieved when debugging.
Sql Server does not (on my knowledge) have in-build Split function. Split function in general on all platforms would have comma-separated string value to be split into individual strings. In sql server, the main objective or necessary of the Split function is to convert a comma-separated string value (‘abc,cde,fgh’) into a temp table with each string as rows.
The below Split function is Table-valued function which would help us splitting comma-separated (or any other delimiter value) string to individual string.
CREATE FUNCTION dbo.Split(@String varchar(8000), @Delimiter char(1))
returns @temptable TABLE (items varchar(8000))
as
begin
declare @idx int
declare @slice varchar(8000)
select @idx = 1
if len(@String)<1 or @String is null return
while @idx!= 0
begin
set @idx = charindex(@Delimiter,@String)
if @idx!=0
set @slice = left(@String,@idx - 1)
else
set @slice = @String
if(len(@slice)>0)
insert into @temptable(Items) values(@slice)
set @String = right(@String,len(@String) - @idx)
if len(@String) = 0 break
end
return
end
select top 10 * from dbo.split('Chennai,Bangalore,Mumbai',',')

to the CSS on your table element.
That will get the words in the table cells to break such that the table does not grow wider than its containing div, yet the table columns are still sized dynamically. jsfiddle demo.
Try adding the dependency.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
The cleanest way to do this that I've seen is with filter
:
removeItem(index) {
this.setState({
data: this.state.data.filter((_, i) => i !== index)
});
}
You could use getopt.
#include <ctype.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
int
main (int argc, char **argv)
{
int bflag = 0;
int sflag = 0;
int index;
int c;
opterr = 0;
while ((c = getopt (argc, argv, "bs")) != -1)
switch (c)
{
case 'b':
bflag = 1;
break;
case 's':
sflag = 1;
break;
case '?':
if (isprint (optopt))
fprintf (stderr, "Unknown option `-%c'.\n", optopt);
else
fprintf (stderr,
"Unknown option character `\\x%x'.\n",
optopt);
return 1;
default:
abort ();
}
printf ("bflag = %d, sflag = %d\n", bflag, sflag);
for (index = optind; index < argc; index++)
printf ("Non-option argument %s\n", argv[index]);
return 0;
}
I had the same issue and took a whole day to figure out the problem. This error message by Facebook SDK is very vague. I had this problem due to openURL: method being overwritten in MyApplication. I removed the overwritten method and facebook login worked fine.
Duplicate rows can be removed for Complex Queries by,
First storing the result to a #TempTable or @TempTableVariable
Delete from #TempTable or @TempTableVariable where your condition
Then select the rest of the data.
If need to create a row number create an identity column.
Java's transient
keyword is used to denote that a field is not to be serialized, whereas JPA's @Transient
annotation is used to indicate that a field is not to be persisted in the database, i.e. their semantics are different.
You could use lodash _get
function:
var object = { 'a': [{ 'b': { 'c': 3 } }] };
_.get(object, 'a[0].b.c');
// => 3
If using Java8 you can get the average of the values from a List as follows:
List<Integer> intList = Arrays.asList(1,2,2,3,1,5);
Double average = intList.stream().mapToInt(val -> val).average().orElse(0.0);
This has the advantage of having no moving parts. It can be easily adapted to work with a List of other types of object by changing the map method call.
For example with Doubles:
List<Double> dblList = Arrays.asList(1.1,2.1,2.2,3.1,1.5,5.3);
Double average = dblList.stream().mapToDouble(val -> val).average().orElse(0.0);
NB. mapToDouble is required because it returns a DoubleStream which has an average
method, while using map
does not.
or BigDecimals:
@Test
public void bigDecimalListAveragedCorrectly() {
List<BigDecimal> bdList = Arrays.asList(valueOf(1.1),valueOf(2.1),valueOf(2.2),valueOf(3.1),valueOf(1.5),valueOf(5.3));
Double average = bdList.stream().mapToDouble(BigDecimal::doubleValue).average().orElse(0.0);
assertEquals(2.55, average, 0.000001);
}
using orElse(0.0)
removes problems with the Optional object returned from the average
being 'not present'.
I also encountered a similar problem. I run Ubuntu 11.04 on VMware on a Windows 7 host OS. Virtual machines can't expose the physical wireless cards. All of that is using a virtualization layer.
You want to set height which may set for all devices?
Decide upon the design of the site i.e Height on various devices.
Ex:
Height-100px
for bubbles on device with -min-width: 700px
.Height-50px
for bubbles on device with < 700px
;Have your css which has height 50px;
and add this media query
@media only screen and (min-width: 700px) {
/* Styles */
.bubble {
height: 100px;
margin: 20px;
}
.bubble:after {
bottom: -50px;
border-width: 50px 50px 0;
}
.bubble:before {
top: 100px;
border-width: 52px 52px 0;
}
.bubble1 {
height: 100px;
margin: 20px;
}
.bubble1:after {
bottom: -50px;
border-width: 50px 50px 0;
}
.bubble1:before {
top: 100px;
border-width: 52px 52px 0;
}
.bubble2 {
height: 100px;
margin: 20px;
}
.bubble2:after {
bottom: -50px;
border-width: 50px 50px 0;
}
.bubble2:before {
top: 100px;
border-width: 52px 52px 0;
}
}
This will make your bubbles have Height of 100px on devices greater than 700px and a margin of 20px;
echo date('d/m/Y', strtotime('+7 days'));
If you're in a .tsx
file you cannot just write <T>
, but this works:
const foo = <T, >(x: T) => x;
As opposed to the extends {}
hack, this hack at least preserves the intent.
Your stylesheet should be thought of as a static table of available variables that your html document can call on based on what you need to display. The logic should be in your javascript and html, use javascript to dynamically apply attributes based on conditions if you really need to. Stylesheets are not the place for logic.
To augment other answers - if you have multiple custom compound views with the same ID and they are all being restored with the state of the last view on a configuration change, all you need to do is tell the view to only dispatch save/restore events to itself by overriding a couple of methods.
class MyCompoundView : ViewGroup {
...
override fun dispatchSaveInstanceState(container: SparseArray<Parcelable>) {
dispatchFreezeSelfOnly(container)
}
override fun dispatchRestoreInstanceState(container: SparseArray<Parcelable>) {
dispatchThawSelfOnly(container)
}
}
For an explanation of what is happening and why this works, see this blog post. Basically your compound view's children's view IDs are shared by each compound view and state restoration gets confused. By only dispatching state for the compound view itself, we prevent their children from getting mixed messages from other compound views.
You can use git add --interactive
or git add -p <file>
, and then git commit
(not git commit -a
); see Interactive mode in git-add manpage, or simply follow instructions.
Modern Git has also git commit --interactive
(and git commit --patch
, which is shortcut to patch option in interactive commit).
If you prefer doing it from GUI, you can use git-gui. You can simply mark chunks which you want to have included in commit. I personally find it easier than using git add -i
. Other git GUIs, like QGit or GitX, might also have this functionality as well.
In your example, the TMP
variable is set (and the temporary directory created) whenever the rules for out.tar
are evaluated. In order to create the directory only when out.tar
is actually fired, you need to move the directory creation down into the steps:
out.tar :
$(eval TMP := $(shell mktemp -d))
@echo hi $(TMP)/hi.txt
tar -C $(TMP) cf $@ .
rm -rf $(TMP)
The eval function evaluates a string as if it had been typed into the makefile manually. In this case, it sets the TMP
variable to the result of the shell
function call.
edit (in response to comments):
To create a unique variable, you could do the following:
out.tar :
$(eval $@_TMP := $(shell mktemp -d))
@echo hi $($@_TMP)/hi.txt
tar -C $($@_TMP) cf $@ .
rm -rf $($@_TMP)
This would prepend the name of the target (out.tar, in this case) to the variable, producing a variable with the name out.tar_TMP
. Hopefully, that is enough to prevent conflicts.
I looked everywhere for an answer and finally this worked for me:
SELECT Lower(Substring(MASTER.dbo.Fn_varbintohexstr(0x21232F297A57A5A743894A0E4A801FC3), 3, 8000))
Outputs to (string):
21232f297a57a5a743894a0e4a801fc3
You can use it in your WHERE or JOIN conditions as well in case you want to compare/match varbinary records with strings
For Spark 2.1.0, my suggestion would be to use head(n: Int)
or take(n: Int)
with isEmpty
, whichever one has the clearest intent to you.
df.head(1).isEmpty
df.take(1).isEmpty
with Python equivalent:
len(df.head(1)) == 0 # or bool(df.head(1))
len(df.take(1)) == 0 # or bool(df.take(1))
Using df.first()
and df.head()
will both return the java.util.NoSuchElementException
if the DataFrame is empty. first()
calls head()
directly, which calls head(1).head
.
def first(): T = head()
def head(): T = head(1).head
head(1)
returns an Array, so taking head
on that Array causes the java.util.NoSuchElementException
when the DataFrame is empty.
def head(n: Int): Array[T] = withAction("head", limit(n).queryExecution)(collectFromPlan)
So instead of calling head()
, use head(1)
directly to get the array and then you can use isEmpty
.
take(n)
is also equivalent to head(n)
...
def take(n: Int): Array[T] = head(n)
And limit(1).collect()
is equivalent to head(1)
(notice limit(n).queryExecution
in the head(n: Int)
method), so the following are all equivalent, at least from what I can tell, and you won't have to catch a java.util.NoSuchElementException
exception when the DataFrame is empty.
df.head(1).isEmpty
df.take(1).isEmpty
df.limit(1).collect().isEmpty
I know this is an older question so hopefully it will help someone using a newer version of Spark.
There's now a full-fledged plugin for that:
Asp.Net Core 3 with System.Text.Json
public void ConfigureServices(IServiceCollection services)
{
services
.AddControllers()
.AddJsonOptions(options =>
options.JsonSerializerOptions.Converters.Add(new JsonStringEnumConverter())
);
//...
}
If You are comparing only with the date vale, then converting it to date (not datetime) will work
select id,numbers_from,created_date,amount_numbers,SMS_text
from Test_Table
where
created_date <= convert(date,'2013-04-12',102)
This conversion is also applicable during using GetDate() function
Here's an example which helps to understand this:
public class Main {
static abstract class A {
abstract void foo();
A() {
System.out.println("Constructing A");
foo();
}
}
static class C extends A {
C() {
System.out.println("Constructing C");
}
void foo() {
System.out.println("Using C");
}
}
public static void main(String[] args) {
C c = new C();
}
}
If you run this code, you get the following output:
Constructing A
Using C
Constructing C
You see? foo()
makes use of C before C's constructor has been run. If foo()
requires C to have a defined state (i.e. the constructor has finished), then it will encounter an undefined state in C and things might break. And since you can't know in A what the overwritten foo()
expects, you get a warning.
In my testing all IMPL classes had the field "pid". This has worked for me:
public static int getPid(Process process) {
try {
Class<?> cProcessImpl = process.getClass();
Field fPid = cProcessImpl.getDeclaredField("pid");
if (!fPid.isAccessible()) {
fPid.setAccessible(true);
}
return fPid.getInt(process);
} catch (Exception e) {
return -1;
}
}
Just make sure the returned value is not -1. If it is, then parse the output of ps
.
It was making me crazy also until I realized that the paragraph where the key must be is [mysqld] not [mysql]
So, for 10.3.22-MariaDB-1ubuntu1, my solution is, in /etc/mysql/conf.d/mysql.cnf
[mysqld]
sql_mode = "ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
You can do it like this:
<input type="hidden" name="result" value="<?php foreach($postvalue as $value) echo $postvalue.","; ?>">
Yes, multiple calls to where() is a perfectly valid way to achieve this.
$this->db->where('username',$username);
$this->db->where('status',$status);
http://www.codeigniter.com/user_guide/database/query_builder.html
This is a very tricky problem since, at least for Symfony 2.0 and Doctrine 2.1, it is not possible in any way to reopen the EntityManager after it closes.
The only way I found to overcome this problem is to create your own DBAL Connection class, wrap the Doctrine one and provide exception handling (e.g. retrying several times before popping the exception out to the EntityManager). It is a bit hacky and I'm afraid it can cause some inconsistency in transactional environments (i.e. I'm not really sure of what happens if the failing query is in the middle of a transaction).
An example configuration to go for this way is:
doctrine:
dbal:
default_connection: default
connections:
default:
driver: %database_driver%
host: %database_host%
user: %database_user%
password: %database_password%
charset: %database_charset%
wrapper_class: Your\DBAL\ReopeningConnectionWrapper
The class should start more or less like this:
namespace Your\DBAL;
class ReopeningConnectionWrapper extends Doctrine\DBAL\Connection {
// ...
}
A very annoying thing is that you have to override each method of Connection providing your exception-handling wrapper. Using closures can ease some pain there.
A cherry-pick is basically a commit, so if you want to undo it, you just undo the commit.
when I have other local changes
Stash your current changes so you can reapply them after resetting the commit.
$ git stash
$ git reset --hard HEAD^
$ git stash pop # or `git stash apply`, if you want to keep the changeset in the stash
when I have no other local changes
$ git reset --hard HEAD^
For angular6+
this.shirtCollection = afs.collection<Shirt>('shirts');
this.shirts = this.shirtCollection.snapshotChanges().pipe(
map(actions => {
return actions.map(a => {
const data = a.payload.doc.data() as Shirt;
const id = a.payload.doc.id;
return { id, ...data };
});
})
);
I know this question is long resolved, but I recently had a similar issue and think I've found a little more elegant and functional solution, although it requires the magrittr package.
library(magrittr)
cols = c(1, 3, 4, 5)
df[,cols] %<>% lapply(function(x) as.numeric(as.character(x)))
The %<>%
operator pipes and reassigns, which is very useful for keeping data cleaning and transformation simple. Now the list apply function is much easier to read, by only specifying the function you wish to apply.
We must define the behavior configuration to REST endpoint
<endpointBehaviors>
<behavior name="restfulBehavior">
<webHttp defaultOutgoingResponseFormat="Json" defaultBodyStyle="Wrapped" automaticFormatSelectionEnabled="False" />
</behavior>
</endpointBehaviors>
and also to a service
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
After the behaviors, next step is the bindings. For example basicHttpBinding to SOAP endpoint and webHttpBinding to REST.
<bindings>
<basicHttpBinding>
<binding name="soapService" />
</basicHttpBinding>
<webHttpBinding>
<binding name="jsonp" crossDomainScriptAccessEnabled="true" />
</webHttpBinding>
</bindings>
Finally we must define the 2 endpoint in the service definition. Attention for the address="" of endpoint, where to REST service is not necessary nothing.
<services>
<service name="ComposerWcf.ComposerService">
<endpoint address="" behaviorConfiguration="restfulBehavior" binding="webHttpBinding" bindingConfiguration="jsonp" name="jsonService" contract="ComposerWcf.Interface.IComposerService" />
<endpoint address="soap" binding="basicHttpBinding" name="soapService" contract="ComposerWcf.Interface.IComposerService" />
<endpoint address="mex" binding="mexHttpBinding" name="metadata" contract="IMetadataExchange" />
</service>
</services>
In Interface of the service we define the operation with its attributes.
namespace ComposerWcf.Interface
{
[ServiceContract]
public interface IComposerService
{
[OperationContract]
[WebInvoke(Method = "GET", UriTemplate = "/autenticationInfo/{app_id}/{access_token}", ResponseFormat = WebMessageFormat.Json,
RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
Task<UserCacheComplexType_RootObject> autenticationInfo(string app_id, string access_token);
}
}
Joining all parties, this will be our WCF system.serviceModel definition.
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="restfulBehavior">
<webHttp defaultOutgoingResponseFormat="Json" defaultBodyStyle="Wrapped" automaticFormatSelectionEnabled="False" />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<basicHttpBinding>
<binding name="soapService" />
</basicHttpBinding>
<webHttpBinding>
<binding name="jsonp" crossDomainScriptAccessEnabled="true" />
</webHttpBinding>
</bindings>
<protocolMapping>
<add binding="basicHttpsBinding" scheme="https" />
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
<services>
<service name="ComposerWcf.ComposerService">
<endpoint address="" behaviorConfiguration="restfulBehavior" binding="webHttpBinding" bindingConfiguration="jsonp" name="jsonService" contract="ComposerWcf.Interface.IComposerService" />
<endpoint address="soap" binding="basicHttpBinding" name="soapService" contract="ComposerWcf.Interface.IComposerService" />
<endpoint address="mex" binding="mexHttpBinding" name="metadata" contract="IMetadataExchange" />
</service>
</services>
</system.serviceModel>
To test the both endpoint, we can use WCFClient to SOAP and PostMan to REST.

I used ASIHTTPRequest a lot like Jane Sales answer but it is not under development anymore and the author suggests using other libraries like AFNetworking.
Honestly, I think now is the time to start looking elsewhere.
AFNetworking works great, and let you work with blocks a lot (which is a great relief).
Here's an image upload example from their documentation page on github:
NSURL *url = [NSURL URLWithString:@"http://api-base-url.com"];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
NSData *imageData = UIImageJPEGRepresentation([UIImage imageNamed:@"avatar.jpg"], 0.5);
NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:@"/upload" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
[formData appendPartWithFileData:imageData name:@"avatar" fileName:@"avatar.jpg" mimeType:@"image/jpeg"];
}];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite);
}];
[httpClient enqueueHTTPRequestOperation:operation];
git branch --set-upstream <remote-branch>
sets the default remote branch for the current local branch.
Any future git pull
command (with the current local branch checked-out),
will attempt to bring in commits from the <remote-branch>
into the current local branch.
One way to avoid having to explicitly type --set-upstream
is to use its shorthand flag -u
as follows:
git push -u origin local-branch
This sets the upstream association for any future push/pull attempts automatically.
For more details, checkout this detailed explanation about upstream branches and tracking.
To avoid confusion, recent versions of
git
deprecate this somewhat ambiguous--set-upstream
option in favour of a more verbose--set-upstream-to
option with identical syntax and behaviourgit branch --set-upstream-to <origin/remote-branch>
I found a way to do it (dont know if it is the best but it works)
string oldFile = "oldFile.pdf";
string newFile = "newFile.pdf";
// open the reader
PdfReader reader = new PdfReader(oldFile);
Rectangle size = reader.GetPageSizeWithRotation(1);
Document document = new Document(size);
// open the writer
FileStream fs = new FileStream(newFile, FileMode.Create, FileAccess.Write);
PdfWriter writer = PdfWriter.GetInstance(document, fs);
document.Open();
// the pdf content
PdfContentByte cb = writer.DirectContent;
// select the font properties
BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252,BaseFont.NOT_EMBEDDED);
cb.SetColorFill(BaseColor.DARK_GRAY);
cb.SetFontAndSize(bf, 8);
// write the text in the pdf content
cb.BeginText();
string text = "Some random blablablabla...";
// put the alignment and coordinates here
cb.ShowTextAligned(1, text, 520, 640, 0);
cb.EndText();
cb.BeginText();
text = "Other random blabla...";
// put the alignment and coordinates here
cb.ShowTextAligned(2, text, 100, 200, 0);
cb.EndText();
// create the new page and add it to the pdf
PdfImportedPage page = writer.GetImportedPage(reader, 1);
cb.AddTemplate(page, 0, 0);
// close the streams and voilá the file should be changed :)
document.Close();
fs.Close();
writer.Close();
reader.Close();
I hope this can be usefull for someone =) (and post here any errors)
Here is the code snippet I found:

You can do it in a simpler way using the DialogResult.cancel
method.
Eg:
Dim anInput as String = InputBox("Enter your pin")
If anInput <>"" then
' Do something
Elseif DialogResult.Cancel then
Msgbox("You've canceled")
End if
Not exactly. But you can create a list of lists:
var ll = new List<List<int>>();
for(int i = 0; i < 10; ++i) {
var l = new List<int>();
ll.Add(l);
}
a late answer, but I think this one works as required in the question :)

You're close. You can strip the whitespace by using the replace
method like this:
$answer.replace(' ','')
There needs to be no space or characters between the second set of quotes in the replace method (replacing the whitespace with nothing).

number of minutes, the cookie will expire and the user will no longer be authenticated—they will be redirected to the login page automatically. The slidingExpiration=true
value is basically saying that as long as the user makes a request within the timeout value, they will continue to be authenticated (more details here). If you set slidingExpiration=false
the authentication cookie will expire after value
number of minutes regardless of whether the user makes a request within the timeout value or not.
The SessionState
timeout value sets the amount of time a Session State provider is required to hold data in memory (or whatever backing store is being used, SQL Server, OutOfProc, etc) for a particular session. For example, if you put an object in Session using the value in your example, this data will be removed after 30 minutes. The user may still be authenticated but the data in the Session may no longer be present. The Session Timeout
value is always reset after every request.
You only need the async
pipe:
<li *ngFor="let afd of afdeling | async">
{{afd.patientid}}
</li>
always use the async
pipe when dealing with Observables directly without explicitly unsubscribe.
I had similar situation as you and I ended up with using external library called arrow.
Here is what it looks like:
>>> import arrow
>>> enter = arrow.get('12:30:45', 'HH:mm:ss')
>>> exit = arrow.now()
>>> duration = exit - enter
>>> duration
datetime.timedelta(736225, 14377, 757451)
We have been using jqGrid on a project and have had some good luck with it. Lots of options for inline editing, etc. If that stuff isn't necessary, then we've just used a plain foreach loop like @Hrvoje.
Open command prompt separately and check:
C:\mongodb\bin\mongoimport --db db_name --collection collection_name< filename.json
I don't think this question has been completely answered yet because all of the answers only give single match examples. The OP's question demonstrates the nuances of having 2 matches as well as a substring match which should not be reported because it is not a word/token.
To match multiple occurrences, one might do something like this:
iter = re.finditer(r"\bis\b", String)
indices = [m.start(0) for m in iter]
This would return a list of the two indices for the original string.
You need to implement IEquatable
or override Equals()
and GetHashCode()
For example:
public class CartProduct : IEquatable<CartProduct>
{
public Int32 ID;
public String Name;
public Int32 Number;
public Decimal CurrentPrice;
public CartProduct(Int32 ID, String Name, Int32 Number, Decimal CurrentPrice)
{
this.ID = ID;
this.Name = Name;
this.Number = Number;
this.CurrentPrice = CurrentPrice;
}
public String ToString()
{
return Name;
}
public bool Equals( CartProduct other )
{
// Would still want to check for null etc. first.
return this.ID == other.ID &&
this.Name == other.Name &&
this.Number == other.Number &&
this.CurrentPrice == other.CurrentPrice;
}
}
For current date just use UNIX_TIMESTAMP()
in your MySQL query.
I find this one most useful.. it gives the most accurate 'H' layout and is very simple to understand.
The benefit in this markup is that you define your content size in a single place -> "PageContent".
The Colors of the page background and its horizontal margins are defined in their corresponding divs.
<div id="PageLayoutConfiguration"
style="display: table;
position:absolute; top: 0px; right: 0px; bottom: 0px; left: 0px;
width: 100%; height: 100%;">
<div id="PageBackground"
style="display: table-cell; vertical-align: middle;
background-color: purple;">
<div id="PageHorizontalMargins"
style="width: 100%;
background-color: seashell;">
<div id="PageContent"
style="width: 1200px; height: 620px; margin: 0 auto;
background-color: grey;">
my content goes here...
</div>
</div>
</div>
</div>
And here with CSS separated:
<div id="PageLayoutConfiguration">
<div id="PageBackground">
<div id="PageHorizontalMargins">
<div id="PageContent">
my content goes here...
</div>
</div>
</div>
</div>
#PageLayoutConfiguration{
display: table; width: 100%; height: 100%;
position:absolute; top: 0px; right: 0px; bottom: 0px; left: 0px;
}
#PageBackground{
display: table-cell; vertical-align: middle;
background-color: purple;
}
#PageHorizontalMargins{
style="width: 100%;
background-color: seashell;
}
#PageContent{
width: 1200px; height: 620px; margin: 0 auto;
background-color: grey;
}
You should't write data-toggle="modal" in the element which triggered the modal (like a button), and you manually can show the modal with:
$('#myModal').modal('show');
and hide with:
$('#myModal').modal('hide');
There are three different approaches to consider, as described in the reference
Position your <div>
absolutely at the bottom and don't forget to give div.A
a position: relative
- http://jsfiddle.net/TTaMx/
.A {
position: relative;
margin: 40px 0;
height: 40px;
width: 200px;
background: #eee;
}
.A:after {
content: " ";
display: block;
background: #c00;
height: 29px;
width: 100%;
position: absolute;
bottom: -29px;
}?
Elements have to paint to an integer number of pixels, and as the other answers covered, percentages are indeed respected.
An important note is that pixels in this case means css pixels, not screen pixels, so a 200px container with a 50.7499% child will be rounded to 101px css pixels, which then get rendered onto 202px on a retina screen, and not 400 * .507499 ~= 203px.
Screen density is ignored in this calculation, and there is no way to paint* an element to specific retina subpixel sizes. You can't have elements' backgrounds or borders rendered at less than 1 css pixel size, even though the actual element's size could be less than 1 css pixel as Sandy Gifford showed.
[*] You can use some techniques like 0.5 offset box-shadow, etc, but the actual box model properties will paint to a full CSS pixel.
With SSL the encryption is at the transport level, so it takes place before a request is sent.
So everything in the request is encrypted.
I had the same problem, needed a modification of [Required] attribute - make field required in dependence of http request.The solution was similar to Dan Hunex answer, but his solution didn't work correctly (see comments). I don't use unobtrusive validation, just MicrosoftMvcValidation.js out of the box. Here it is. Implement your custom attribute:
public class RequiredIfAttribute : RequiredAttribute
{
public RequiredIfAttribute(/*You can put here pararmeters if You need, as seen in other answers of this topic*/)
{
}
protected override ValidationResult IsValid(object value, ValidationContext context)
{
//You can put your logic here
return ValidationResult.Success;//I don't need its server-side so it always valid on server but you can do what you need
}
}
Then you need to implement your custom provider to use it as an adapter in your global.asax
public class RequreIfValidator : DataAnnotationsModelValidator <RequiredIfAttribute>
{
ControllerContext ccontext;
public RequreIfValidator(ModelMetadata metadata, ControllerContext context, RequiredIfAttribute attribute)
: base(metadata, context, attribute)
{
ccontext = context;// I need only http request
}
//override it for custom client-side validation
public override IEnumerable<ModelClientValidationRule> GetClientValidationRules()
{
//here you can customize it as you want
ModelClientValidationRule rule = new ModelClientValidationRule()
{
ErrorMessage = ErrorMessage,
//and here is what i need on client side - if you want to make field required on client side just make ValidationType "required"
ValidationType =(ccontext.HttpContext.Request["extOperation"] == "2") ? "required" : "none";
};
return new ModelClientValidationRule[] { rule };
}
}
And modify your global.asax with a line
DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(RequiredIfAttribute), typeof(RequreIfValidator));
and here it is
[RequiredIf]
public string NomenclatureId { get; set; }
The main advantage for me is that I don't have to code custom client validator as in case of unobtrusive validation. it works just as [Required], but only in cases that you want.
it should work using - (void)scrollToRowAtIndexPath:(NSIndexPath *)indexPath atScrollPosition:(UITableViewScrollPosition)scrollPosition animated:(BOOL)animated
using it this way:
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[yourTableView scrollToRowAtIndexPath:indexPath
atScrollPosition:UITableViewScrollPositionTop
animated:YES];
atScrollPosition
could take any of these values:
typedef enum {
UITableViewScrollPositionNone,
UITableViewScrollPositionTop,
UITableViewScrollPositionMiddle,
UITableViewScrollPositionBottom
} UITableViewScrollPosition;
I hope this helps you

With SSL/https and with CSRF_COOKIE_HTTPONLY = False, I still don't have csrftoken in the cookie, either using the getCookie(name) function proposed in django Doc or the jquery.cookie.js proposed by fivef.
Wtower summary is perfect and I thought it would work after removing CSRF_COOKIE_HTTPONLY from settings.py but it does'nt in https!
Why csrftoken is not visible in document.cookie???
Instead of getting
"django_language=fr; csrftoken=rDrGI5cp98MnooPIsygWIF76vuYTkDIt"
I get only
"django_language=fr"
WHY? Like SSL/https removes X-CSRFToken from headers I thought it was due to the proxy header params of Nginx but apparently not... Any idea?
Unlike django doc Notes, it seems impossible to work with csrf_token in cookies with https. The only way to pass csrftoken is through the DOM by using {% csrf_token %} in html and get it in jQuery by using
var csrftoken = $('input[name="csrfmiddlewaretoken"]').val();
It is then possible to pass it to ajax either by header (xhr.setRequestHeader), either by params.
Here are some ways to edit the text and the size of the box:
rows="insertNumber"
cols="insertNumber"
style="font-size:12pt"
Example:

Text Here</textarea>
<asp:RadioButtonList ID="rblRequestType">
<asp:ListItem Selected="True" Value="value1">Value1</asp:ListItem>
<asp:ListItem Value="Value2">Value2</asp:ListItem>
</asp:RadioButtonList>
You can set checked like this.
var radio0 = $("#rblRequestType_0");
var radio1 = $("#rblRequestType_1");
radio0.checked = true;
radio1.checked = true;

FYI, I am using Windows 7 and had to restart Windows in order for the new JAVA_HOME setting to take effect.
What you're doing is a static include. A static include is resolved at compile time, and may thus not use a parameter value, which is only known at execution time.
What you need is a dynamic include:
<jsp:include page="..." />
Note that you should use the JSP EL rather than scriptlets. It also seems that you're implementing a central controller with index.jsp. You should use a servlet to do that instead, and dispatch to the appropriate JSP from this servlet. Or better, use an existing MVC framework like Stripes or Spring MVC.
I don't know what the .tex extension on your file means. If we are saying that it is any file with any extension you have several methods of reading it.
I have to assume you are using windows because you have mentioned notepad++.
Use notepad++. Right click on the file and choose "edit with notepad++"
Use notepad Change the filename extension to .txt and double click the file.
Use command prompt. Open the folder that your file is in. Hold down shift and right click. (not on the file, but in the folder that the file is in.) Choose "open command window here" from the command prompt type: "type filename.tex"
If these don't work, I would need more detail as to how they are not working. Errors that you may be getting or what you may expect to be in the file might help.
Although John Leidegren keeps shooting down the idea, Brian is correct. I've just got it working in Visual Studio.
To be clear a WPF application does not create a Console window by default.
You have to create a WPF Application and then change the OutputType to "Console Application". When you run the project you will see a console window with your WPF window in front of it.
It doesn't look very pretty, but I found it helpful as I wanted my app to be run from the command line with feedback in there, and then for certain command options I would display the WPF window.
If you work with an IDE like NetBeans, you can specify the Xlint:unchecked
compiler option in the propertys of your project.
Just go to projects window, right click in the project and then click in Properties
.
In the window that appears search the Compiling
category, and in the textbox labeled Additional Compiler Options
set the Xlint:unchecked
option.
Thus, the setting will remain set for every time you compile the project.

I know that Jason's answer was accepted, but I had the same problem with Mongoose and found that the service hosting my database recommended to apply the following settings in order to keep Mongodb's connection alive in production:
var options = {
server: { socketOptions: { keepAlive: 1, connectTimeoutMS: 30000 } },
replset: { socketOptions: { keepAlive: 1, connectTimeoutMS: 30000 } }
};
mongoose.connect(secrets.db, options);
I hope that this reply may help other people having "Topology was destroyed" errors.
Another way of doing it is in custom JsonObjectRequest by:
@Override
public RetryPolicy getRetryPolicy() {
// here you can write a custom retry policy and return it
return super.getRetryPolicy();

This is almost identical to how Karl Shifflet demonstrated a RelayCommand
, where Execute
fires a predetermined Action<T>
. A top-notch solution, if you ask me.
public class RelayCommand : ICommand
{
private readonly Predicate<object> _canExecute;
private readonly Action<object> _execute;
public RelayCommand(Predicate<object> canExecute, Action<object> execute)
{
_canExecute = canExecute;
_execute = execute;
}
public event EventHandler CanExecuteChanged
{
add => CommandManager.RequerySuggested += value;
remove => CommandManager.RequerySuggested -= value;
}
public bool CanExecute(object parameter)
{
return _canExecute(parameter);
}
public void Execute(object parameter)
{
_execute(parameter);
}
}
This could then be used as...
public class MyViewModel
{
private ICommand _doSomething;
public ICommand DoSomethingCommand
{
get
{
if (_doSomething == null)
{
_doSomething = new RelayCommand(
p => this.CanDoSomething,
p => this.DoSomeImportantMethod());
}
return _doSomething;
}
}
}

encodeURIComponent works fine for me. we can give the url like this in ajax call.The code shown below:
$.ajax({
cache: false,
type: "POST",
url: "http://atandra.mivamerchantdev.com//mm5/json.mvc?Store_Code=ATA&Function=Module&Module_Code=thub_connector&Module_Function=THUB_Request",
data: "strChannelName=" + $('#txtupdstorename').val() + "&ServiceUrl=" + encodeURIComponent($('#txtupdserviceurl').val()),
dataType: "HTML",
success: function (data) {
},
error: function (xhr, ajaxOptions, thrownError) {
}
});
In later versions of JQuery they have changed the function from select to activate. http://api.jqueryui.com/tabs/#event-activate
I'm guessing that the field you are trying to save the value in is a datetime field it's not but the same seems to be true for timestamps. If so mysql expects the format to be Year-month-day Hour:minute:second. In order to save the timestamp you will have to convert the field to numeric using a query like
alter table <table_name> change <field> <field> bigint unsigned
If you are using the current time you can use now() or current_timestamp.
You can be also interested what updates are available for plugins. For that, you have to merge the data about installed plugins with information about updates available here https://updates.jenkins.io/current/update-center.json .
To parse the downloaded file as a JSON you have to read online the second line (which is huge).

delete_all is a single SQL DELETE statement and nothing more. destroy_all calls destroy() on all matching results of :conditions (if you have one) which could be at least NUM_OF_RESULTS SQL statements.
If you have to do something drastic such as destroy_all() on large dataset, I would probably not do it from the app and handle it manually with care. If the dataset is small enough, you wouldn't hurt as much.

For such task, you should really be using PHP's DateTime class. Please ignore all of the answers advising you to use date() or date_set_time_zone, it's simply bad and outdated.
I'll use pseudocode to demonstrate, so try to adjust the code to suit your needs.
Assuming that variable $tz contains string name of a valid time zone and variable $timestamp contains the timestamp you wish to format according to time zone, the code would look like this:
$tz = 'Europe/London';
$timestamp = time();
$dt = new DateTime("now", new DateTimeZone($tz)); //first argument "must" be a string
$dt->setTimestamp($timestamp); //adjust the object to correct timestamp
echo $dt->format('d.m.Y, H:i:s');
DateTime class is powerful, and to grasp all of its capabilities - you should devote some of your time reading about it at php.net. To answer your question fully - yes, you can adjust the time zone parameter dynamically (on each iteration while reading from db, you can create a new DateTimeZone() object).
The virtual keyword is used to modify a method, property, indexer, or event declaration and allow for it to be overridden in a derived class. For example, this method can be overridden by any class that inherits it:
public virtual double Area()
{
return x * y;
}
You cannot use the virtual modifier with the static, abstract, private, or override modifiers. The following example shows a virtual property:
class MyBaseClass
{
// virtual auto-implemented property. Overrides can only
// provide specialized behavior if they implement get and set accessors.
public virtual string Name { get; set; }
// ordinary virtual property with backing field
private int num;
public virtual int Number
{
get { return num; }
set { num = value; }
}
}
class MyDerivedClass : MyBaseClass
{
private string name;
// Override auto-implemented property with ordinary property
// to provide specialized accessor behavior.
public override string Name
{
get
{
return name;
}
set
{
if (value != String.Empty)
{
name = value;
}
else
{
name = "Unknown";
}
}
}
}
Just add the following line in your build.sbt
PlayKeys.devSettings := Seq("play.server.http.port" -> "8080")
Change the "MSBuild project build output verbosity" to "Detailed" or above. To do this, follow these steps:
In the tools/options page that appears, set the MSBuild project build output verbosity level to the appropriate setting depending on your version:
Check out the MSBuild messages. The ResolveAssemblyReferences
task, which is the task from which MSB3247 originates, should help you debug this particular issue.
My specific case was an incorrect reference to SqlServerCe. See below. I had two projects referencing two different versions of SqlServerCe. I went to the project with the older version, removed the reference, then added the correct reference.
Target ResolveAssemblyReferences:
Consider app.config remapping of assembly "System.Data.SqlServerCe, ..."
from Version "3.5.1.0" [H:\...\Debug\System.Data.SqlServerCe.dll]
to Version "9.0.242.0" [C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\PublicAssemblies\System.Data.SqlServerCe.dll]
to solve conflict and get rid of warning.
C:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets :
warning MSB3247: Found conflicts between different versions of the same dependent assembly.
You do not have to open each assembly to determine the versions of referenced assemblies.
If you're on a browser that supports it you can use CSS to transform the <a>
into a table row:
.table-row { display: table-row; }
.table-cell { display: table-cell; }
<div style="display: table;">
<a href="..." class="table-row">
<span class="table-cell">This is a TD... ish...</span>
</a>
</div>
Of course, you're limited to not putting block elements inside the <a>
.
You also can't mix this in with a regular <table>
Sub TEST()
Dim value1 As String
Dim value2 As String
value1 = ThisWorkbook.Sheets(1).Range("A1").Value 'value from sheet1
value2 = ThisWorkbook.Sheets(2).Range("A1").Value 'value from sheet2
If value1 = value2 Then ThisWorkbook.Sheets(2).Range("L1").Value = value1 'or 2
End Sub
This will compare two sheets cells values and if they match place the value on sheet 2 in column L.

The last couple of answers are almost correct - I have tons of apps that generate messages that need to end up with different consumers so the process is very simple.
If you want multiple consumers to the same message, do the following procedure.
Create multiple queues, one for each app that is to receive the message, in each queue properties, "bind" a routing tag with the amq.direct exchange. Change you publishing app to send to amq.direct and use the routing-tag (not a queue). AMQP will then copy the message into each queue with the same binding. Works like a charm :)
Example: Lets say I have a JSON string I generate, I publish it to the "amq.direct" exchange using the routing tag "new-sales-order", I have a queue for my order_printer app that prints order, I have a queue for my billing system that will send a copy of the order and invoice the client and I have a web archive system where I archive orders for historic/compliance reasons and I have a client web interface where orders are tracked as other info comes in about an order.
So my queues are: order_printer, order_billing, order_archive and order_tracking All have the binding tag "new-sales-order" bound to them, all 4 will get the JSON data.
This is an ideal way to send data without the publishing app knowing or caring about the receiving apps.
Just to make it complete, there is another difference when using the Equals
method, which is inherited by all classes and structures.
Lets's say we have a class and a structure:
class A{
public int a, b;
}
struct B{
public int a, b;
}
and in the Main method, we have 4 objects.
static void Main{
A c1 = new A(), c2 = new A();
c1.a = c1.b = c2.a = c2.b = 1;
B s1 = new B(), s2 = new B();
s1.a = s1.b = s2.a = s2.b = 1;
}
Then:
s1.Equals(s2) // true
s1.Equals(c1) // false
c1.Equals(c2) // false
c1 == c2 // false
So, structures are suited for numeric-like objects, like points (save x and y coordinates). And classes are suited for others. Even if 2 people have same name, height, weight..., they are still 2 people.

Statically typed languages like C++, Java and Dynamically typed languages like Python differ only in terms of the execution of the type of the variable. Statically typed languages have static data type for the variable, here the data type is checked during compiling so debugging is much simpler...whereas Dynamically typed languages don't do the same, the data type is checked which executing the program and hence the debugging is bit difficult.
Moreover they have a very small difference and can be related with strongly typed and weakly typed languages. A strongly typed language doesn't allow you to use one type as another eg. C and C++ ...whereas weakly typed languages allow eg.python
I got this answer from the book Programming iOS 7, section Bar Position and Bar Metrics
If a navigation bar or toolbar — or a search bar (discussed earlier in this chapter) — is to occupy the top of the screen, the iOS 7 convention is that its height should be increased to underlap the transparent status bar. To make this possible, iOS 7 introduces the notion of a bar position.
Specifies that the bar is at the top of the screen, as well as its containing view. Bars with this position draw their background extended upwards, allowing their background content to show through the status bar. Available in iOS 7.0 and later.
Using your code, this is how I would do it. I know an answer was chosen, just giving additional options.
data = json.loads('{"lat":444, "lon":555}')
ret = ''
for j in data:
ret = ret+" "+data[j]
return ret
When you use for in this manor you get the key of the object, not the value, so you can get the value, by using the key as an index.
Sometimes the provided solution by @palotasb is not sufficient. There are use cases where for example a "Filter" submits button is placed above buttons like "Next and Previous". I found a workaround for this: copy the submit button which needs to act as the default submit button in a hidden div and place it inside the form above any other submit button. Technically it will be submitted by a different button when pressing Enter than when clicking on the visible Next button. But since the name and value are the same, there's no difference in the result.

<style>
div.defaultsubmitbutton {
display: none;

x = [1, 1, 2, 4]
y = [1, 2, 2, 2]
# intersection
x & y # => [1, 2]
# union
x | y # => [1, 2, 4]
# difference
x - y # => [4]
textarea {
white-space: pre;
overflow-wrap: normal;
overflow-x: scroll;
}
white-space: nowrap
also works if you don't care about whitespace, but of course you don't want that if you're working with code (or indented paragraphs or any content where there might deliberately be multiple spaces) ... so i prefer pre
.
overflow-wrap: normal
(was word-wrap
in older browsers) is needed in case some parent has changed that setting; it can cause wrapping even if pre
is set.
also -- contrary to the currently accepted answer -- textareas do often wrap by default. pre-wrap
seems to be the default on my browser.
You could check for the size of the array.
package sojava;
import java.util.ArrayList;
public class Main {
public static Object get(ArrayList list, int index) {
if (list.size() > index) { return list.get(index); }
return null;
}
public static void main(String[] args) {
ArrayList list = new ArrayList();
list.add(""); list.add(""); list.add("");
System.out.println(get(list, 4));
// prints 'null'
}
}

Here is Blake's excellent answer as an extension method. Add this to your project and the calls in the question will work as expected.
Meaning it is used like MyNullableDateTime.ToString("dd/MM/yyyy")
, with the same output as MyDateTime.ToString("dd/MM/yyyy")
, except that the value will be "N/A"
if the DateTime is null.
public static string ToString(this DateTime? date, string format)
{
return date != null ? date.Value.ToString(format) : "N/A";
}
Missing from these answers is how to get a file dialog without a input element on the page.
The function to show the input file dialog.
function openFileDialog (accept, callback) { // this function must be called from a user
// activation event (ie an onclick event)
// Create an input element
var inputElement = document.createElement("input");
// Set its type to file
inputElement.type = "file";
// Set accept to the file types you want the user to select.
// Include both the file extension and the mime type
inputElement.accept = accept;
// set onchange event to call callback when user has selected file
inputElement.addEventListener("change", callback)
// dispatch a click event to open the file dialog
inputElement.dispatchEvent(new MouseEvent("click"));
}
NOTE the function must be part of a user activation such as a click event. Attempting to open the file dialog without user activation will fail.
NOTE
input.accept
is not used in Edge
Calling above function when user clicks an anchor element.
// wait for window to load
window.addEventListener("load", windowLoad);
// open a dialog function
function openFileDialog (accept, multy = false, callback) {
var inputElement = document.createElement("input");
inputElement.type = "file";
inputElement.accept = accept; // Note Edge does not support this attribute
if (multy) {
inputElement.multiple = multy;
}
if (typeof callback === "function") {
inputElement.addEventListener("change", callback);
}
inputElement.dispatchEvent(new MouseEvent("click"));
}
// onload event
function windowLoad () {
// add user click event to userbutton
userButton.addEventListener("click", openDialogClick);
}
// userButton click event
function openDialogClick () {
// open file dialog for text files
openFileDialog(".txt,text/plain", true, fileDialogChanged);
}
// file dialog onchange event handler
function fileDialogChanged (event) {
[...this.files].forEach(file => {
var div = document.createElement("div");
div.className = "fileList common";
div.textContent = file.name;
userSelectedFiles.appendChild(div);
});
}

Warning the above snippet is written in ES6.
INSERT INTO `table` ( `data` , `date` ) VALUES('".$data."',NOW()+INTERVAL 1 DAY);
Firstly find out the number's starting length then reverse the string to find out the first position again(which will give you end position of number from the end). Now if you deduct 1 from both number and deduct it from string whole length you'll get only number length. Now get the number using SUBSTRING
declare @fieldName nvarchar(100)='AAAA1221.121BBBB'
declare @lenSt int=(select PATINDEX('%[0-9]%', @fieldName)-1)
declare @lenEnd int=(select PATINDEX('%[0-9]%', REVERSE(@fieldName))-1)
select SUBSTRING(@fieldName, PATINDEX('%[0-9]%', @fieldName), (LEN(@fieldName) - @lenSt -@lenEnd))
If you want to find all records that are not NULL, and either empty or have any number of spaces, this will work:
LIKE '%\ '
Make sure that there's a space after the backslash. More info here: http://dev.mysql.com/doc/refman/5.0/en/string-comparison-functions.html
There's no problem with using a localhost url for Dev work - obviously it needs to be changed when it comes to production.
You need to go here: https://developers.google.com/accounts/docs/OAuth2 and then follow the link for the API Console - link's in the Basic Steps section. When you've filled out the new application form you'll be asked to provide a redirect Url. Put in the page you want to go to once access has been granted.
When forming the Google oAuth Url - you need to include the redirect url - it has to be an exact match or you'll have problems. It also needs to be UrlEncoded.
<xsl:call-template>
is a close equivalent to calling a function in a traditional programming language.
You can define functions in XSLT, like this simple one that outputs a string.
<xsl:template name="dosomething">
<xsl:text>A function that does something</xsl:text>
</xsl:template>
This function can be called via <xsl:call-template name="dosomething">
.
<xsl:apply-templates>
is a little different and in it is the real power of XSLT: It takes any number of XML nodes (whatever you define in the select
attribute), iterates them (this is important: apply-templates works like a loop!) and finds matching templates for them:
<!-- sample XML snippet -->
<xml>
<foo /><bar /><baz />
</xml>
<!-- sample XSLT snippet -->
<xsl:template match="xml">
<xsl:apply-templates select="*" /> <!-- three nodes selected here -->
</xsl:template>
<xsl:template match="foo"> <!-- will be called once -->
<xsl:text>foo element encountered</xsl:text>
</xsl:template>
<xsl:template match="*"> <!-- will be called twice -->
<xsl:text>other element countered</xsl:text>
</xsl:template>
This way you give up a little control to the XSLT processor - not you decide where the program flow goes, but the processor does by finding the most appropriate match for the node it's currently processing.
If multiple templates can match a node, the one with the more specific match expression wins. If more than one matching template with the same specificity exist, the one declared last wins.
You can concentrate more on developing templates and need less time to do "plumbing". Your programs will become more powerful and modularized, less deeply nested and faster (as XSLT processors are optimized for template matching).
A concept to understand with XSLT is that of the "current node". With <xsl:apply-templates>
the current node moves on with every iteration, whereas <xsl:call-template>
does not change the current node. I.e. the .
within a called template refers to the same node as the .
in the calling template. This is not the case with apply-templates.
This is the basic difference. There are some other aspects of templates that affect their behavior: Their mode
and priority
, the fact that templates can have both a name
and a match
. It also has an impact whether the template has been imported (<xsl:import>
) or not. These are advanced uses and you can deal with them when you get there.
do the client machines have python loaded? if so, I'm doing this with psexec
On my local machine, I use subprocess in my .py file to call a command line.
import subprocess
subprocess.call("psexec {server} -c {}")
the -c copies the file to the server so i can run any executable file (which in your case could be a .bat full of connection tests or your .py file from above).
I came here searching for the same answer, but based on the top answers, I came up with an easier code. Hope this will help future searches.

As Django documentation says:
prefetch_related()
Returns a QuerySet that will automatically retrieve, in a single batch, related objects for each of the specified lookups.
This has a similar purpose to select_related, in that both are designed to stop the deluge of database queries that is caused by accessing related objects, but the strategy is quite different.
select_related works by creating an SQL join and including the fields of the related object in the SELECT statement. For this reason, select_related gets the related objects in the same database query. However, to avoid the much larger result set that would result from joining across a ‘many’ relationship, select_related is limited to single-valued relationships - foreign key and one-to-one.
prefetch_related, on the other hand, does a separate lookup for each relationship, and does the ‘joining’ in Python. This allows it to prefetch many-to-many and many-to-one objects, which cannot be done using select_related, in addition to the foreign key and one-to-one relationships that are supported by select_related. It also supports prefetching of GenericRelation and GenericForeignKey, however, it must be restricted to a homogeneous set of results. For example, prefetching objects referenced by a GenericForeignKey is only supported if the query is restricted to one ContentType.

while i do also like the answer posted by @Alex, i offer this variation to @Graham's solution above
this exclusively uses record existence in the INSERTED and UPDATED tables, as opposed to using COLUMNS_UPDATED for the first test. It also provides the paranoid programmer relief knowing that the final case has been considered...
declare @action varchar(4)
IF EXISTS (SELECT * FROM INSERTED)
BEGIN
IF EXISTS (SELECT * FROM DELETED)
SET @action = 'U' -- update
ELSE
SET @action = 'I' --insert
END
ELSE IF EXISTS (SELECT * FROM DELETED)
SET @action = 'D' -- delete
else
set @action = 'noop' --no records affected
--print @action
you will get NOOP with a statement like the following :
update tbl1 set col1='cat' where 1=2
The Function adds gaussian , salt-pepper , poisson and speckle noise in an image
Parameters
----------
image : ndarray
Input image data. Will be converted to float.
mode : str
One of the following strings, selecting the type of noise to add:
'gauss' Gaussian-distributed additive noise.
'poisson' Poisson-distributed noise generated from the data.
's&p' Replaces random pixels with 0 or 1.
'speckle' Multiplicative noise using out = image + n*image,where
n is uniform noise with specified mean & variance.
import numpy as np
import os
import cv2
def noisy(noise_typ,image):
if noise_typ == "gauss":
row,col,ch= image.shape
mean = 0
var = 0.1
sigma = var**0.5
gauss = np.random.normal(mean,sigma,(row,col,ch))
gauss = gauss.reshape(row,col,ch)
noisy = image + gauss
return noisy
elif noise_typ == "s&p":
row,col,ch = image.shape
s_vs_p = 0.5
amount = 0.004
out = np.copy(image)
# Salt mode
num_salt = np.ceil(amount * image.size * s_vs_p)
coords = [np.random.randint(0, i - 1, int(num_salt))
for i in image.shape]
out[coords] = 1
# Pepper mode
num_pepper = np.ceil(amount* image.size * (1. - s_vs_p))
coords = [np.random.randint(0, i - 1, int(num_pepper))
for i in image.shape]
out[coords] = 0
return out
elif noise_typ == "poisson":
vals = len(np.unique(image))
vals = 2 ** np.ceil(np.log2(vals))
noisy = np.random.poisson(image * vals) / float(vals)
return noisy
elif noise_typ =="speckle":
row,col,ch = image.shape
gauss = np.random.randn(row,col,ch)
gauss = gauss.reshape(row,col,ch)
noisy = image + image * gauss
return noisy
Yet another possibility, up to the last note of the OP, is to compare the hashes (SHA
or MD
) of the dicts dumped as JSON. The way hashes are constructed guarantee that if they are equal, the source strings are equal as well. This is very fast and mathematically sound.
import json
import hashlib
def hash_dict(d):
return hashlib.sha1(json.dumps(d, sort_keys=True)).hexdigest()
x = dict(a=1, b=2)
y = dict(a=2, b=2)
z = dict(a=1, b=2)
print(hash_dict(x) == hash_dict(y))
print(hash_dict(x) == hash_dict(z))
The other answers are all valid, however, if you are still having a problem you might not have your class inside the src folder in which case Eclipse may not see it as part of the project. This would also invoke the same error message you have seen.
What about in a situation where you have a Service that's holding state for example. How could I push changes to that Service, and other random components on the page be aware of such a change? Been struggling with tackling this problem lately
Build a service with RxJS Extensions for Angular.
<script src="//unpkg.com/angular/angular.js"></script>
<script src="//unpkg.com/rx/dist/rx.all.js"></script>
<script src="//unpkg.com/rx-angular/dist/rx.angular.js"></script>
var app = angular.module('myApp', ['rx']);
app.factory("DataService", function(rx) {
var subject = new rx.Subject();
var data = "Initial";
return {
set: function set(d){
data = d;
subject.onNext(d);
},
get: function get() {
return data;
},
subscribe: function (o) {
return subject.subscribe(o);
}
};
});
Then simply subscribe to the changes.
app.controller('displayCtrl', function(DataService) {
var $ctrl = this;
$ctrl.data = DataService.get();
var subscription = DataService.subscribe(function onNext(d) {
$ctrl.data = d;
});
this.$onDestroy = function() {
subscription.dispose();
};
});
Clients can subscribe to changes with DataService.subscribe
and producers can push changes with DataService.set
.

I also ran into this issue just now while messing with laravel.
