MongoDB 2.2's new $elemMatch
projection operator provides another way to alter the returned document to contain only the first matched shapes
element:
db.test.find(
{"shapes.color": "red"},
{_id: 0, shapes: {$elemMatch: {color: "red"}}});
Returns:
{"shapes" : [{"shape": "circle", "color": "red"}]}
In 2.2 you can also do this using the $ projection operator
, where the $
in a projection object field name represents the index of the field's first matching array element from the query. The following returns the same results as above:
db.test.find({"shapes.color": "red"}, {_id: 0, 'shapes.$': 1});
MongoDB 3.2 Update
Starting with the 3.2 release, you can use the new $filter
aggregation operator to filter an array during projection, which has the benefit of including all matches, instead of just the first one.
db.test.aggregate([
// Get just the docs that contain a shapes element where color is 'red'
{$match: {'shapes.color': 'red'}},
{$project: {
shapes: {$filter: {
input: '$shapes',
as: 'shape',
cond: {$eq: ['$$shape.color', 'red']}
}},
_id: 0
}}
])
Results:
[
{
"shapes" : [
{
"shape" : "circle",
"color" : "red"
}
]
}
]
The problem seems to happen when you have an alias the same name as the objects property. Hibernate seems to pick up the alias and use it in the sql. I found this documented here and here, and I believe it to be a bug in Hibernate, although I am not sure that the Hibernate team agrees.
Either way, I have found a simple work around that works in my case. Your mileage may vary. The details are below, I tried to simplify the code for this sample so I apologize for any errors or typo's:
Criteria criteria = session.createCriteria(MyClass.class)
.setProjection(Projections.projectionList()
.add(Projections.property("sectionHeader"), "sectionHeader")
.add(Projections.property("subSectionHeader"), "subSectionHeader")
.add(Projections.property("sectionNumber"), "sectionNumber"))
.add(Restrictions.ilike("sectionHeader", sectionHeaderVar)) // <- Problem!
.setResultTransformer(Transformers.aliasToBean(MyDTO.class));
Would produce this sql:
select
this_.SECTION_HEADER as y1_,
this_.SUB_SECTION_HEADER as y2_,
this_.SECTION_NUMBER as y3_,
from
MY_TABLE this_
where
( lower(y1_) like ? )
Which was causing an error: java.sql.SQLException: ORA-00904: "Y1_": invalid identifier
But, when I changed my restriction to use "this", like so:
Criteria criteria = session.createCriteria(MyClass.class)
.setProjection(Projections.projectionList()
.add(Projections.property("sectionHeader"), "sectionHeader")
.add(Projections.property("subSectionHeader"), "subSectionHeader")
.add(Projections.property("sectionNumber"), "sectionNumber"))
.add(Restrictions.ilike("this.sectionHeader", sectionHeaderVar)) // <- Problem Solved!
.setResultTransformer(Transformers.aliasToBean(MyDTO.class));
It produced the following sql and my problem was solved.
select
this_.SECTION_HEADER as y1_,
this_.SUB_SECTION_HEADER as y2_,
this_.SECTION_NUMBER as y3_,
from
MY_TABLE this_
where
( lower(this_.SECTION_HEADER) like ? )
Thats, it! A pretty simple fix to a painful problem. I don't know how this fix would translate to the query by example problem, but it may get you closer.
Not sure this answers the question but I believe it's worth mentioning here.
There is one more way for selecting single field (and not multiple) using db.collection_name.distinct();
e.g.,db.student.distinct('roll',{});
Or, 2nd way: Using db.collection_name.find().forEach();
(multiple fields can be selected here by concatenation)
e.g., db.collection_name.find().forEach(function(c1){print(c1.roll);});
Check out array_merge()
.
$array3 = array_merge($array1, $array2);
Udhay's sample code works well. Except the question of Sofiane Hassaini and Chirag SolankI, for the re-entrance, it doesn't work. I try to call Udhay's code without restart the activity in onCreate() , before super.onCreate(savedInstanceState);. Then it is OK! Only a little problem, the menu strings still not changed to the set Locale.
public void setLocale(String lang) { //call this in onCreate()
Locale myLocale = new Locale(lang);
Resources res = getResources();
DisplayMetrics dm = res.getDisplayMetrics();
Configuration conf = res.getConfiguration();
conf.locale = myLocale;
res.updateConfiguration(conf, dm);
//Intent refresh = new Intent(this, AndroidLocalize.class);
//startActivity(refresh);
//finish();
}
As noted in a prior answer, although git merge-base
works,
$ git merge-base myfeature develop
050dc022f3a65bdc78d97e2b1ac9b595a924c3f2
If myfeature
is the current branch, as is common, you can use --fork-point
:
$ git merge-base --fork-point develop
050dc022f3a65bdc78d97e2b1ac9b595a924c3f2
This argument works only in sufficiently recent versions of git. Unfortunately it doesn't always work, however, and it is not clear why. Please refer to the limitations noted toward the end of this answer.
For full commit info, consider:
$ git log -1 $(git merge-base --fork-point develop)
A solution combining find and replace methods in a single line if statement could be:
```python
my_var = "stackoverflaw"
my_new_var = my_var.replace('a', 'o', 1) if my_var.find('s') != -1 else my_var
print(f"my_var = {my_var}") # my_var = stackoverflaw
print(f"my_new_var = {my_new_var}") # my_new_var = stackoverflow
```
The easiest way would be to use a GUI:
For Gnome use gnome-schedule (universe)
sudo apt-get install gnome-schedule
For KDE use kde-config-cron
It should be pre installed on Kubuntu
But if you use a headless linux or don´t want GUI´s you may use:
crontab -e
If you type it into Terminal you´ll get a table.
You have to insert your cronjobs now.
Format a job like this:
* * * * * YOURCOMMAND
- - - - -
| | | | |
| | | | +----- Day in Week (0 to 7) (Sunday is 0 and 7)
| | | +------- Month (1 to 12)
| | +--------- Day in Month (1 to 31)
| +----------- Hour (0 to 23)
+------------- Minute (0 to 59)
There are some shorts, too (if you don´t want the *):
@reboot --> only once at startup
@daily ---> once a day
@midnight --> once a day at midnight
@hourly --> once a hour
@weekly --> once a week
@monthly --> once a month
@annually --> once a year
@yearly --> once a year
If you want to use the shorts as cron (because they don´t work or so):
@daily --> 0 0 * * *
@midnight --> 0 0 * * *
@hourly --> 0 * * * *
@weekly --> 0 0 * * 0
@monthly --> 0 0 1 * *
@annually --> 0 0 1 1 *
@yearly --> 0 0 1 1 *
given the following examples
here are your possible servernames:
A shorter version to test undefined variable can simply be:
test -z ${mystr} && echo "mystr is not defined"
I had met a similar problem, after i add a scope property of servlet dependency in pom.xml
<dependency>
<groupId>javax.servlet</groupId>

<scope>provided</scope>
</dependency>
Then it was ok . maybe that will help you.
In addition to the nested scrolling NestedScrollView
added one major functionality, which could even make it interesting outside of nested contexts: It has build in support for OnScrollChangeListener
. Adding a OnScrollChangeListener
to the original ScrollView
below API 23 required subclassing ScrollView
or messing around with the ViewTreeObserver
of the ScrollView
which often means even more work than subclassing. With NestedScrollView
it can be done using the build-in setter.
I ran into this error while trying to click some element (or its overlay, I didn't care), and the other answers didn't work for me. I fixed it by using the elementFromPoint
DOM API to find the element that Selenium wanted me to click on instead:
element_i_care_about = something()
loc = element_i_care_about.location
element_to_click = driver.execute_script(
"return document.elementFromPoint(arguments[0], arguments[1]);",
loc['x'],
loc['y'])
element_to_click.click()
I've also had situations where an element was moving, for example because an element above it on the page was doing an animated expand or collapse. In that case, this Expected Condition class helped. You give it the elements that are animated, not the ones you want to click. This version only works for jQuery animations.
class elements_not_to_be_animated(object):
def __init__(self, locator):
self.locator = locator
def __call__(self, driver):
try:
elements = EC._find_elements(driver, self.locator)
# :animated is an artificial jQuery selector for things that are
# currently animated by jQuery.
return driver.execute_script(
'return !jQuery(arguments[0]).filter(":animated").length;',
elements)
except StaleElementReferenceException:
return False
Do you want to change database?
\l - to display databases

In my case, I have macport installed already. I simply updated my macport:
sudo port selfupdate
sudo port upgrade outdated
Then install apache-ant:
sudo port install apache-ant
Finally, I add ant to my alias list in my .bash_profile
:
alias ant='/opt/local/bin/ant'
Then you are all set.
You can create a recursive function like this to do a depth-first traversal of the cars
object.
var findObjectByLabel = function(obj, label) {
if(obj.label === label) { return obj; }
for(var i in obj) {
if(obj.hasOwnProperty(i)){
var foundLabel = findObjectByLabel(obj[i], label);
if(foundLabel) { return foundLabel; }
}
}
return null;
};
which can be called like so
findObjectByLabel(car, "Chevrolet");
DECLARE @q nvarchar(4000)
SET @q = 'DECLARE @tmp TABLE (code VARCHAR(50), mount MONEY)
INSERT INTO @tmp
(
code,
mount
)
SELECT coa_code,
amount
FROM T_Ledger_detail
SELECT *
FROM @tmp'
EXEC sp_executesql @q
If you want in dynamic query
#ifndef <token>
/* code */
#else
/* code to include if the token is defined */
#endif
#ifndef
checks whether the given token has been #defined
earlier in the file or in an included file; if not, it includes the code between it and the closing #else
or, if no #else
is present, #endif
statement. #ifndef
is often used to make header files idempotent by defining a token once the file has been included and checking that the token was not set at the top of that file.
#ifndef _INCL_GUARD
#define _INCL_GUARD
#endif
Or you can do
docker run -v /var/volume1 -v /var/volume2 DATA busybox true
mark a text area by mark command say ma and mb type command: :'a,'bg/(.*)/s////\1/
You can see an example of this kind of test manipulation at http://bknpk.ddns.net/my_web/VIM/vim_shell_cmd_on_block.html
With most Awk implementations:
awk 'BEGIN {srand(); print srand()}'
If it shows an error on the first run only, it's probably because you haven't sent any POST data. You should check for POST variables before working with them. Undefined, null, empty array, empty string, etc. are all considered false; and when PHP auto-casts that false boolean value to an integer or a float, it becomes zero. That's what happens with your variables, they are not set on the first run, and thus are treated as zeroes.
10 / $unsetVariable
becomes
10 / 0
Bottom line: check if your inputs exist and if they are valid before doing anything with them, also enable error reporting when you're doing local work as it will save you a lot of time. You can enable all errors to be reported like this: error_reporting(E_ALL);
To fix your specific problem: don't do any calculations if there's no input from your form; just show the form instead.

You can calculate the cumulative sum list in linear time with a simple for
loop:
def csum(lst):
s = lst.copy()
for i in range(1, len(s)):
s[i] += s[i-1]
return s
time_interval = [4, 6, 12]
print(csum(time_interval)) # [4, 10, 22]
The standard library's itertools.accumulate
may be a faster alternative (since it's implemented in C):
from itertools import accumulate
time_interval = [4, 6, 12]
print(list(accumulate(time_interval))) # [4, 10, 22]
It's because you have turned on USB debugging in Developer Options. You can create a bug report by holding the power + both volume up and down.

By pressing Volume up + Volume down + power button, you will feel a vibration after a second or so, that's when the bug reporting initiated.

The equals( )
method and the ==
operator perform two different operations. The equals( )
method compares the characters inside a String
object. The ==
operator compares two object references to see whether they refer to the same instance. The following program shows how two different String objects can contain the same characters, but references to these objects will not compare as equal:
// equals() vs ==
class EqualsNotEqualTo {
public static void main(String args[]) {
String s1 = "Hello";
String s2 = new String(s1);
System.out.println(s1 + " equals " + s2 + " -> " +
s1.equals(s2));
System.out.println(s1 + " == " + s2 + " -> " + (s1 == s2));
}
}
The variable s1
refers to the String instance created by “Hello”
. The object referred to by
s2
is created with s1
as an initializer. Thus, the contents of the two String objects are identical,
but they are distinct objects. This means that s1
and s2
do not refer to the same objects and
are, therefore, not ==
, as is shown here by the output of the preceding example:
Hello equals Hello -> true
Hello == Hello -> false
String.Join(" ", myList)
or String.Join(" ", myList.ToArray())
. The first argument is the separator between the substrings.
var myList = new List<String> { "foo","bar","baz"};
Console.WriteLine(String.Join("-", myList)); // prints "foo-bar-baz"
Depending on your version of .NET you might need to use ToArray() on the list first..
If anyone from the future also wanders up here:
docker-compose exec container_name sh

Answer is very Simple. You Must use app.engine('html') to render *.html Pages. try this.It must Solve the Problem.
app.set('views', path.join(__dirname, 'views'));
**// Set EJS View Engine**
app.set('view engine','ejs');
**// Set HTML engine**
app.engine('html', require('ejs').renderFile);
the .html file Will work
codaddict has provided the right answer. As for what you've tried, I'll explain why they don't make the cut:
[0-9]{1,45}
is almost there, however it matches a 1-to-45-digit string even if it occurs within another longer string containing other characters. Hence you need ^
and $
to restrict it to an exact match.
^[0-9]{45}*$
matches an exactly-45-digit string, repeated 0 or any number of times (*
). That means the length of the string can only be 0 or a multiple of 45 (90, 135, 180...).
In eclipse go to the DDMS perspective and in the devices tab click the process you want to kill under the device you want to kill it on. You then just need to press the stop button and it should kill the process.
I'm not sure how you'd do this from the command line tool but there must be a way. Maybe you do it through the adb shell...
The compiled dll should have public Class.
Simplified example (with counter):
With Me.lstbox
.ColumnCount = 2
.ColumnWidths = "60;60"
.AddItem
.List(i, 0) = Company_ID
.List(i, 1) = Company_name
i = i + 1
end with
Make sure to start the counter with 0, not 1 to fill up a listbox.

In Python self
is the conventional name given to the first argument of instance methods of classes, which is always the instance the method was called on:
class A(object):
def f(self):
print self
a = A()
a.f()
Will give you something like
<__main__.A object at 0x02A9ACF0>
To stick to ==
without consideration of the other type, the following is also possible.
type(a) == type(None)
The following takes any valid datetime value and returns the number of days in the associated month... it eliminates the ambiguity of both other answers...
// pass in any date as parameter anyDateInMonth
function daysInMonth(anyDateInMonth) {

anyDateInMonth.getMonth()+1,
0).getDate();}
Simply add the following style attribute in your Button
tag:
style="?android:attr/borderlessButtonStyle"
source: http://developer.android.com/guide/topics/ui/controls/button.html#Borderless
Then you can add dividers as in Karl's answer.
Once you are in terminal/command line, access the database/collection you want to use as follows:
show dbs
use <db name>
show collections
choose your collection and type the following to see all contents of that collection:
db.collectionName.find()

After editing .gitignore
to match the ignored files, you can do git ls-files -ci --exclude-standard
to see the files that are included in the exclude lists; you can then do
git ls-files -ci --exclude-standard -z | xargs -0 git rm --cached
git ls-files -ci --exclude-standard | % { git rm --cached "$_" }
for /F "tokens=*" %a in ('git ls-files -ci --exclude-standard') do @git rm --cached "%a"
to remove them from the repository (without deleting them from disk).
Edit: You can also add this as an alias in your .gitconfig file so you can run it anytime you like. Just add the following line under the [alias] section (modify as needed for Windows or Mac):
apply-gitignore = !git ls-files -ci --exclude-standard -z | xargs -0 git rm --cached
(The -r
flag in xargs
prevents git rm
from running on an empty result and printing out its usage message, but may only be supported by GNU findutils. Other versions of xargs
may or may not have a similar option.)
Now you can just type git apply-gitignore
in your repo, and it'll do the work for you!
My way of Insert

You're trying to create a tuple, but you're just parenthesizing a string :)
Add an extra ',':
dRecieved = connFile.readline()
processThread = threading.Thread(target=processLine, args=(dRecieved,)) # <- note extra ','
processThread.start()
Or use brackets to make a list:
dRecieved = connFile.readline()
processThread = threading.Thread(target=processLine, args=[dRecieved]) # <- 1 element list
processThread.start()
If you notice, from the stack trace: self.__target(*self.__args, **self.__kwargs)
The *self.__args
turns your string into a list of characters, passing them to the processLine
function. If you pass it a one element list, it will pass that element as the first argument - in your case, the string.
I know you asked about NotePad++ but TextMate for OS X can do it via the JSON bundle, its called the "Reformat Document" command.
I have a short answer which I have used in a project. In my answer, I consider that you have visitor IP address.
$ip = "202.142.178.220";
$ipdat = @json_decode(file_get_contents("http://www.geoplugin.net/json.gp?ip=" . $ip));
//get ISO2 country code
if(property_exists($ipdat, 'geoplugin_countryCode')) {
echo $ipdat->geoplugin_countryCode;

//get country full name
if(property_exists($ipdat, 'geoplugin_countryName')) {
echo $ipdat->geoplugin_countryName;
}
A nice practical use of this is if you want to make your own HtmlHelper
extensions. For example, I hate trying to remember the <link>
tag syntax, so I've created my own extension method to make a <link>
tag:
<Extension()> _
Public Function CssBlock(ByVal html As HtmlHelper, ByVal src As String, ByVal Optional ByVal htmlAttributes As Object = Nothing) As MvcHtmlString
Dim tag = New TagBuilder("link")
tag.MergeAttribute("type", "text/css")
tag.MergeAttribute("rel", "stylesheet")
tag.MergeAttribute("href", src)
tag.MergeAttributes(New RouteValueDictionary(htmlAttributes))
Dim result = tag.ToString(TagRenderMode.Normal)
Return MvcHtmlString.Create(result)
End Function
I could have returned String
from this method, but if I had the following would break:
<%: Html.CssBlock(Url.Content("~/sytles/mysite.css")) %>
With MvcHtmlString
, using either <%: ... %>
or <%= ... %>
will both work correctly.
You can remove "JavaAppletPlugin.plugin" found in Spotlight or Finder, then re-install downloaded Java 8.

I just started using STS Eclipse with first time using Maven. The project I setup already had its own settings.xml. If this is the case, you'll want to update your settings.xml file in run configuration.
right click the pom.xml and "Run As" -> "Run Configurations..."
where it says "User settings" click on the File button and add the settings.xml.
I think this is specific to your project but my "Goals" is set to "clean install" and I checked on "Skip Tests."

So to add a user icon, just add 
to the placeholder
attribute, or wherever you want it.
You may want to check this cheat sheet.
Example:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">_x000D_
<input type="text" class="form-control" placeholder=" placeholder..." style="font-family: 'Glyphicons Halflings', Arial">_x000D_
<input type="text" class="form-control" value=" value..." style="font-family: 'Glyphicons Halflings', Arial">_x000D_
<input type="submit" class="btn btn-primary" value=" submit-button" style="font-family: 'Glyphicons Halflings', Arial">
_x000D_
Don't forget to set the input's font to the Glyphicon one, using the following code:
font-family: 'Glyphicons Halflings', Arial
, where Arial is the font of the regular text in the input.
In A, 3 is tested for equality against each member of the set, yielding (FALSE, FALSE, TRUE, UNKNOWN). Since one of the elements is TRUE, the condition is TRUE. (It's also possible that some short-circuiting takes place here, so it actually stops as soon as it hits the first TRUE and never evaluates 3=NULL.)
In B, I think it is evaluating the condition as NOT (3 in (1,2,null)). Testing 3 for equality against the set yields (FALSE, FALSE, UNKNOWN), which is aggregated to UNKNOWN. NOT ( UNKNOWN ) yields UNKNOWN. So overall the truth of the condition is unknown, which at the end is essentially treated as FALSE.
To solve, you need to import Private Certificate (PFX).
If you don't have PFX, use OpenSSL to generate it:
Open command line and run:
openssl pkcs12 -export -in public_certificate.cer -inkey server.key -out private_certificate.pfx
Than, install private_certificate.pfx (right click -> Install Certificate).
Now, your certificate does not disappear anymore and you can bind Website over SSL.

To make cURL follow a redirect, use:

call.
EDIT: If you just want to find out where a page redirects to, I'd use the advice here, and just use Curl to grab the headers and extract the Location: header from them:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
if (preg_match('~Location: (.*)~i', $result, $match)) {
$location = trim($match[1]);
}
I just add both these in my app.module.ts:
"import { HttpClientModule } from '@angular/common/http';
&
import { HttpModule } from '@angular/http';"
Now its works fine.... And dont forget to add in the
@NgModule => Imports:[] array
If you want that all normal output of your Batch script be silent (like in your example), the easiest way to do that is to run the Batch file with a redirection:
C:\Temp> test.bat >nul
This method does not require to modify a single line in the script and it still show error messages in the screen. To supress all the output, including error messages:
C:\Temp> test.bat >nul 2>&1
If your script have lines that produce output you want to appear in screen, perhaps will be simpler to add redirection to those lineas instead of all the lines you want to keep silent:
@ECHO OFF
SET scriptDirectory=%~dp0
COPY %scriptDirectory%test.bat %scriptDirectory%test2.bat
FOR /F %%f IN ('dir /B "%scriptDirectory%*.noext"') DO (
del "%scriptDirectory%%%f"
)
ECHO
REM Next line DO appear in the screen
ECHO Script completed >con
Antonio
Inside your script file, put all of the commands within parentheses, like this:
(
echo start
ls -l
echo end
) | tee foo.log
for (Map.Entry<String, Tab> entry : hash.entrySet()) {
String key = entry.getKey();
Tab tab = entry.getValue();
// do something with key and/or tab
}
Works like a charm.
Try this:
@Html.ActionLink("DisplayText", "Action", "Controller", route, attribute)
in your code should be,
@Html.ActionLink("Search", "List", "Search", new{@class="btn btn-info", @id="addressSearch"})
This is a very simple process. Yes, you cannot get the width and height in PHP. It is true that JQuery can provide the screen's width and height. First go to https://github.com/carhartl/jquery-cookie and get jquery.cookie.js. Here is example using php to get the screen width and height:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Test</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js"></script>
<script src="js/jquery.cookie.js"></script>
<script type=text/javascript>
function setScreenHWCookie() {
$.cookie('sw',screen.width);
$.cookie('sh',screen.height);
return true;
}
setScreenHWCookie();
</script>
</head>
<body>
<h1>Using jquery.cookie.js to store screen height and width</h1>
<?php
if(isset($_COOKIE['sw'])) { echo "Screen width: ".$_COOKIE['sw']."<br/>";}
if(isset($_COOKIE['sh'])) { echo "Screen height: ".$_COOKIE['sh']."<br/>";}
?>
</body>
</html>
I have a test that you can execute: http://rw-wrd.net/test.php
When calling a function that is declared with throws
in Swift, you must annotate the function call site with try
or try!
. For example, given a throwing function:
func willOnlyThrowIfTrue(value: Bool) throws {
if value { throw someError }
}
this function can be called like:
func foo(value: Bool) throws {
try willOnlyThrowIfTrue(value)
}
Here we annotate the call with try
, which calls out to the reader that this function may throw an exception, and any following lines of code might not be executed. We also have to annotate this function with throws
, because this function could throw an exception (i.e., when willOnlyThrowIfTrue()
throws, then foo
will automatically rethrow the exception upwards.
If you want to call a function that is declared as possibly throwing, but which you know will not throw in your case because you're giving it correct input, you can use try!
.
func bar() {
try! willOnlyThrowIfTrue(false)
}
This way, when you guarantee that code won't throw, you don't have to put in extra boilerplate code to disable exception propagation.
try!
is enforced at runtime: if you use try!
and the function does end up throwing, then your program's execution will be terminated with a runtime error.
Most exception handling code should look like the above: either you simply propagate exceptions upward when they occur, or you set up conditions such that otherwise possible exceptions are ruled out. Any clean up of other resources in your code should occur via object destruction (i.e. deinit()
), or sometimes via defer
ed code.
func baz(value: Bool) throws {
var filePath = NSBundle.mainBundle().pathForResource("theFile", ofType:"txt")
var data = NSData(contentsOfFile:filePath)
try willOnlyThrowIfTrue(value)
// data and filePath automatically cleaned up, even when an exception occurs.
}
If for whatever reason you have clean up code that needs to run but isn't in a deinit()
function, you can use defer
.
func qux(value: Bool) throws {
defer {
print("this code runs when the function exits, even when it exits by an exception")
}
try willOnlyThrowIfTrue(value)
}
Most code that deals with exceptions simply has them propagate upward to callers, doing cleanup on the way via deinit()
or defer
. This is because most code doesn't know what to do with errors; it knows what went wrong, but it doesn't have enough information about what some higher level code is trying to do in order to know what to do about the error. It doesn't know if presenting a dialog to the user is appropriate, or if it should retry, or if something else is appropriate.
Higher level code, however, should know exactly what to do in the event of any error. So exceptions allow specific errors to bubble up from where they initially occur to the where they can be handled.
Handling exceptions is done via catch
statements.
func quux(value: Bool) {
do {
try willOnlyThrowIfTrue(value)
} catch {
// handle error
}
}
You can have multiple catch statements, each catching a different kind of exception.
do {
try someFunctionThatThowsDifferentExceptions()
} catch MyErrorType.errorA {
// handle errorA
} catch MyErrorType.errorB {
// handle errorB
} catch {
// handle other errors
}
For more details on best practices with exceptions, see http://exceptionsafecode.com/. It's specifically aimed at C++, but after examining the Swift exception model, I believe the basics apply to Swift as well.
For details on the Swift syntax and error handling model, see the book The Swift Programming Language (Swift 2 Prerelease).
Communicating through processes
Example:
Python: This python code block should return random temperatures.
# sensor.py
import random, time
while True:
time.sleep(random.random() * 5) # wait 0 to 5 seconds
temperature = (random.random() * 20) - 5 # -5 to 15
print(temperature, flush=True, end='')
Javascript (Nodejs): Here we will need to spawn a new child process to run our python code and then get the printed output.
// temperature-listener.js
const { spawn } = require('child_process');
const temperatures = []; // Store readings
const sensor = spawn('python', ['sensor.py']);
sensor.stdout.on('data', function(data) {
// convert Buffer object to Float
temperatures.push(parseFloat(data));
console.log(temperatures);
});
I prefer an id descendant selector of your #form2, like this:
$("#form2 #name").val("Hello World!");
Try this one
where datediff(month, datetime_column, getdate()) <= 6
To exclude or filter out future dates
where datediff(month, datetime_column, getdate()) between 0 and 6
This part datediff(month, datetime_column, getdate())
will get the month difference in number of current date and Datetime_Column and will return Rows like:
Result
1
2
3
4
5
6
7
8
9
10
This is Our final condition to get last 6 months data
where result <= 6
In general, one doesn't expand out log(a + b)
; you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:
log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)
(In fact, this identity is often used when implementing log
in math libraries).
For visualization and summary of PyTorch
models, tensorboardX can also can be utilized.
follow some steps below:
open cygwin setup again
choose catagory on view tab
fill "make" in search tab
expand devel
find "make: a GNU version of the 'make' ultility", click to install
Done!
Console applications will exit when the main function has finished running. A "return" will achieve this.
static void Main(string[] args)
{
while (true)
{
Console.WriteLine("I'm running!");
return; //This will exit the console application's running thread
}
}
If you're returning an error code you can do it this way, which is accessible from functions outside of the initial thread:
System.Environment.Exit(-1);
.myDiv { height: 150px; width 150px; }
<div class="mainDiv">
<div class="myDiv"></div>
<div class="myDiv"></div>
<div class="myDiv"></div>
</div>
Maybe Iterator’s remove() method? The JDK’s default collection classes should all creator iterators that support this method.
Same, but different, but still same (can be "tested" multiple times):
const a = { valueOf: () => this.n = (this.n || 0) % 3 + 1}_x000D_
_x000D_
if(a == 1 && a == 2 && a == 3) {_x000D_
console.log('Hello World!');_x000D_
}_x000D_
_x000D_
if(a == 1 && a == 2 && a == 3) {_x000D_
console.log('Hello World!');_x000D_
}
_x000D_
My idea started from how Number object type equation works.
The fastest running code would be carefully hand crafted machine code. Assembler will be almost as good. Both are very low level and it takes a lot of writing code to do things. C is a little above assembler. You still have the ability to control things at a very low level in the actual machine, but there is enough abstraction make writing it faster and easier then assembler. Other languages such as C# and JAVA are even more abstract. While Assembler and machine code are called low level languages, C# and JAVA (and many others) are called high level languages. C is sometimes called a middle level language.
Use whichever suits your need.

$('#table1').find("tr:gt(0)").remove();
PS:To remove specific row number as following example
$('#table1 tr').eq(1).remove();
or
$('#tr:nth-child(2)').remove();
TEXT
is a string data type that can store up to 65,535 characters.
But still if you want to store more data then change its data type to LONGTEXT
ALTER TABLE name_tabel
CHANGE text_field
LONGTEXT CHARACTER SET utf8
COLLATE utf8_general_ci
NOT NULL;
In case you're reading text from the clipboard in a Chrome extension, with 'clipboardRead' permission allowed, you can use the below code:
function readTextFromClipboardInChromeExtension() {
var ta = $('<textarea/>');
$('body').append(ta);
ta.focus();
document.execCommand('paste');
var text = ta.val();
ta.blur();
ta.remove();
return text;
}

Thanks to @Dampas for starting point. https://stackoverflow.com/a/33354009/1011746
Your code won't work because you haven't assigned anything to n
before you first use it. Try this:
def oracle():
n = None
while n != 'Correct':
# etc...
A more readable approach is to move the test until later and use a break
:
def oracle():
guess = 50
while True:
print 'Current number = {0}'.format(guess)
n = raw_input("lower, higher or stop?: ")
if n == 'stop':
break
# etc...
Also input
in Python 2.x reads a line of input and then evaluates it. You want to use raw_input
.
Note: In Python 3.x, raw_input
has been renamed to input
and the old input
method no longer exists.
$product_id = $this->input->get('id', TRUE);
echo $product_id;
Apache part - enabling you to open https://localhost/xyz
There is the config file xampp/apache/conf/extra/httpd-ssl.conf which contains all the ssl specific configuration. It's fairly well documented, so have a read of the comments and take look at http://httpd.apache.org/docs/2.2/ssl/.
The files starts with <IfModule ssl_module>
, so it only has an effect if the apache has been started with its mod_ssl module.
Open the file xampp/apache/conf/httpd.conf in an editor and search for the line
#LoadModule ssl_module modules/mod_ssl.so
remove the hashmark, save the file and re-start the apache. The webserver should now start with xampp's basic/default ssl confguration; good enough for testing but you might want to read up a bit more about mod_ssl in the apache documentation.
PHP part - enabling adldap to use ldap over ssl
adldap needs php's openssl extension to use "ldap over ssl" connections. The openssl extension ships as a dll with xampp. You must "tell" php to load this dll, e.g. by having an extension=nameofmodule.dll
in your php.ini
Run
echo 'ini: ', get_cfg_var('cfg_file_path');
It should show you which ini file your php installation uses (may differ between the php-apache-module and the php-cli version).
Open this file in an editor and search for
;extension=php_openssl.dll
remove the semicolon, save the file and re-start the apache.
This two commands work for me in my project
composer require laravel/ui --dev
Then
php artisan ui:auth
This feature has been built-in into Atom editor (see: symbols-view
package), but you need to generate ctags symbols file for your project GH-9, GH-20.
To do that, install ctags
command (e.g. brew install ctags
on macOS), then:
Append, link or copy ctags-config
to your ~/.ctags
, example on macOS:
ln -vs "$(find /Applications/Atom.app -name ctags-config -print -quit)" ~/.ctags
Go to your project folder and run:
cd your/project/directory
ctags -R .
Restart Atom editor.
Alternatively you can use symbol-gen
package to generate ctags symbols file for your project based on the options found in .ctags
file. You can install it from Atom Package Manager by: apm install symbol-gen
. Then hit CMD-Alt-G to generate tags file for your project.
After following above, you can use Go To Declaration option from the context menu.
On macOS you can use also use the following keyboard shortcuts:
If you're in a heavily concurrent environment, then pure functional programming is useful. The lack of mutable state makes concurrency almost trivial. See Erlang.
In a multiparadigm language, you may want to model some things functionally if the existence of mutable state is must an implementation detail, and thus FP is a good model for the problem domain. For example, see list comprehensions in Python or std.range in the D programming language. These are inspired by functional programming.
I have nice solution that i would like to share. First you need to detect if user is on mobile like this:
var touchDevice = /ipad|iphone|android|windows phone|blackberry/i.test(navigator.userAgent.toLowerCase());
Then just add:
if (!touchDevice) {
$(".navbar-ul").addClass("hoverable");
}
And in CSS:
.navbar-ul.hoverable li a:hover {
color: #fff;
}
set ROOT=c:\programs
set SRC_ROOT=%ROOT%\System\Source
You should use this example with AUTHID CURRENT_USER :
CREATE OR REPLACE PROCEDURE Create_sequence_for_tab (VAR_TAB_NAME IN VARCHAR2)
AUTHID CURRENT_USER
IS
SEQ_NAME VARCHAR2 (100);
FINAL_QUERY VARCHAR2 (100);
COUNT_NUMBER NUMBER := 0;
cur_id NUMBER;
BEGIN
SEQ_NAME := 'SEQ_' || VAR_TAB_NAME;
SELECT COUNT (*)
INTO COUNT_NUMBER
FROM USER_SEQUENCES
WHERE SEQUENCE_NAME = SEQ_NAME;
DBMS_OUTPUT.PUT_LINE (SEQ_NAME || '>' || COUNT_NUMBER);
IF COUNT_NUMBER = 0
THEN
--DBMS_OUTPUT.PUT_LINE('DROP SEQUENCE ' || SEQ_NAME);
-- EXECUTE IMMEDIATE 'DROP SEQUENCE ' || SEQ_NAME;
-- ELSE
SELECT 'CREATE SEQUENCE COMPTABILITE.' || SEQ_NAME || ' START WITH ' || ROUND (DBMS_RANDOM.VALUE (100000000000, 999999999999), 0) || ' INCREMENT BY 1'
INTO FINAL_QUERY
FROM DUAL;
DBMS_OUTPUT.PUT_LINE (FINAL_QUERY);
cur_id := DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.parse (cur_id, FINAL_QUERY, DBMS_SQL.v7);
DBMS_SQL.CLOSE_CURSOR (cur_id);
-- EXECUTE IMMEDIATE FINAL_QUERY;
END IF;

The stuff about about mypath.split("\\")
would be better expressed as mypath.split(os.sep)
. sep
is the path separator for your particular platform (e.g., \
for Windows, /
for Unix, etc.), and the Python build knows which one to use. If you use sep
, then your code will be platform agnostic.
In Windows 10 do the following steps: - Download and install the 'Everything' application that locates files and folders by name instantly. - Find the 'devenv.exe' and locate it.
Convert your x-axis data from text to datetime.datetime
, use datetime.strptime
:
>>> from datetime import datetime
>>> datetime.strptime("2012-may-31 19:00", "%Y-%b-%d %H:%M")
datetime.datetime(2012, 5, 31, 19, 0)
This is an example of how to plot data once you have an array of datetimes:
import matplotlib.pyplot as plt
import datetime
import numpy as np
x = np.array([datetime.datetime(2013, 9, 28, i, 0) for i in range(24)])
y = np.random.randint(100, size=x.shape)
plt.plot(x,y)
plt.show()
If you want to stay with underscore so your predicate function can be more flexible, here are 2 ideas.
Since the predicate for _.find
receives both the value and index of an element, you can use side effect to retrieve the index, like this:
var idx;
_.find(tv, function(voteItem, voteIdx){
if(voteItem.id == voteID){ idx = voteIdx; return true;};
});
Looking at underscore source, this is how _.find
is implemented:
_.find = _.detect = function(obj, predicate, context) {
var result;
any(obj, function(value, index, list) {
if (predicate.call(context, value, index, list)) {
result = value;
return true;
}
});
return result;
};
To make this a findIndex
function, simply replace the line result = value;
with result = index;
This is the same idea as the first method. I included it to point out that underscore uses side effect to implement _.find
as well.
Another solution for class based vanilla JS using a distance threshold
private initDetectDrag(element) {
let clickOrigin = { x: 0, y: 0 };
const dragDistanceThreshhold = 20;
element.addEventListener('mousedown', (event) => {
this.isDragged = false
clickOrigin = { x: event.clientX, y: event.clientY };
});
element.addEventListener('mousemove', (event) => {
if (Math.sqrt(Math.pow(clickOrigin.y - event.clientY, 2) + Math.pow(clickOrigin.x - event.clientX, 2)) > dragDistanceThreshhold) {
this.isDragged = true
}
});
}
Add inside the class (SOMESLIDER_ELEMENT can also be document to be global):
private isDragged: boolean;
constructor() {
this.initDetectDrag(SOMESLIDER_ELEMENT);
this.doSomeSlideStuff(SOMESLIDER_ELEMENT);
element.addEventListener('click', (event) => {
if (!this.sliderIsDragged) {
console.log('was clicked');
} else {
console.log('was dragged, ignore click or handle this');
}
}, false);
}
I know it's an old question and it has been solved already but for me the Tomcat conf/tomcat-users.xml file was created with a different encoding from the rest of the configuration files. The first line of that file looked like this:
<?xml version='1.0' encoding='cp65001'?>
All I had to do to solve the issue was change that line for:
<?xml version="1.0" encoding="UTF-8"?>
And voila.
I have no idea what 'cp65001'
means or why it was created like that.
Maybe this will help other users facing the same issue.
If you have this in your CSS file:
.myApp
{
border-bottom-color:#FF0000;
}
and a div for instance of:
<div id="myDiv">test text</div>
you can use:
$("#myDiv").addClass('myApp');// to add the style
$("#myDiv").removeClass('myApp');// to remove the style
or you can just use
$("#myDiv").css( 'border-bottom-color','#FF0000');
I prefer the first example, keeping all the CSS related items in the CSS files.
I had a ton of trouble with this and then found a great solution:
Create a file in a text editor called whoami.php with the below code as it's content, save the file and upload it to public_html (or whatever you root of your webserver directory is named). It should output a useful string that you can use to track down the user the webserver is running as, my output was "php is running as user: nt authority\iusr" which allowed me to track down the permissions I needed to modify to the user "IUSR".
<?php
// outputs the username that owns the running php/httpd process
// (on a system with the "whoami" executable in the path)
echo 'php is running as user: ' . exec('whoami');
?>
I didn't found any particular answer to this question but i deleted the emulator and create a new one and increase the Ram size of the new emulator.Then the emulator works fine.
Here is some code I've wrote to automatically turn URL's into links and automatically embed any video urls from youtube. I made it for a chat room I'm working on and it works pretty well. I'm sure it will work just fine for any other purpose as well like a blog for instance.
All you have to do is call the function "autolink()" and pass it the string to be parsed.
For example include the function below and then echo this code.
`
echo '<div id="chat_message">'.autolink($string).'</div>';
/****************Function to include****************/
<?php
function autolink($string){
// force http: on www.
$string = str_ireplace( "www.", "http://www.", $string );
// eliminate duplicates after force
$string = str_ireplace( "http://http://www.", "http://www.", $string );
$string = str_ireplace( "https://http://www.", "https://www.", $string );
// The Regular Expression filter
$reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
// Check if there is a url in the text
$m = preg_match_all($reg_exUrl, $string, $match);
if ($m) {
$links=$match[0];
for ($j=0;$j<$m;$j++) {
if(substr($links[$j], 0, 18) == 'http://www.youtube'){
$string=str_replace($links[$j],'<a href="'.$links[$j].'" rel="nofollow" target="_blank">'.$links[$j].'</a>',$string).'<br /><iframe title="YouTube video player" class="youtube-player" type="text/html" width="320" height="185" src="http://www.youtube.com/embed/'.substr($links[$j], -11).'" frameborder="0" allowFullScreen></iframe><br />';
}else{
$string=str_replace($links[$j],'<a href="'.$links[$j].'" rel="nofollow" target="_blank">'.$links[$j].'</a>',$string);
}
}
}
return ($string);
}
?>

The new Chosen libraries don't use the liszt. I used the following:
document.getElementById('autoship_option').selectedIndex = 0;
$("#autoship_option").trigger("chosen:updated");
I had the same problem. I tried 'yyyy-mm-dd' format i.e. '2013-26-11' and got rid of this problem...
It depends on if you mean the list items are below the previous or to the right of the previous, ie:

The first one you can do simply with:
#wrapper { width:600px; background: yellow; margin: 0 auto; }
#footer ul { text-align: center; list-style-type: none; }
The second could be done like this:
#wrapper { width:600px; background: yellow; margin: 0 auto; }
#footer ul { text-align: center; list-style-type: none; }
#footer li { display: inline; }
#footer a { padding: 2px 12px; background: orange; text-decoration: none; }
#footer a:hover { background: green; color: yellow; }
According to the javadoc a Scanner
does not seem to be intended for reading single characters. You attach a Scanner
to an InputStream
(or something else) and it parses the input for you. It also can strip of unwanted characters. So you can read numbers, lines, etc. easily. When you need only the characters from your input, use a InputStreamReader for example.
The number variables are the matches from the last successful match or substitution operator you applied:
my $string = 'abcdefghi';
if ($string =~ /(abc)def(ghi)/) {
print "I found $1 and $2\n";
}
Always test that the match or substitution was successful before using $1
and so on. Otherwise, you might pick up the leftovers from another operation.
Perl regular expressions are documented in perlre.
Arrays
in Java have a defined size, you cannot change it later by adding or removing elements (you can read some basics here).
Instead, use a List
:
ArrayList<String> mylist = new ArrayList<String>();
mylist.add(mystring); //this adds an element to the list.
Of course, if you know beforehand how many strings you are going to put in your array, you can create an array of that size and set the elements by using the correct position:
String[] myarray = new String[numberofstrings];
myarray[23] = string24; //this sets the 24'th (first index is 0) element to string24.
In addition to Doug Kavendek answer. One could use the following approach to get closer to tz_database.
var shapeFile = new ShapeFile(shapeFilePath); var shapeIndex = shapeFile.GetShapeIndexContainingPoint(new PointD(long, lat), 0D); var attrValues = shapeFile.GetAttributeFieldValues(shapeIndex); var timeZoneId = attrValues[0];
P.S. Can't insert all the links :( So please use search.

As alternative, you can code something like this:
<Border
x:Name="borderBtnAdd"
BorderThickness="1"
BorderBrush="DarkGray"
CornerRadius="360"
Height="30"
Margin="0,10,10,0"
VerticalAlignment="Top" HorizontalAlignment="Right" Width="30">
<Image x:Name="btnAdd"
Source="Recursos/Images/ic_add_circle_outline_black_24dp_2x.png"
Width="{Binding borderBtnAdd.Width}" Height="{Binding borderBtnAdd.Height}"/>
</Border>
The "Button" will look something like this:
You could set any other content instead of the image.
There are multiple ways to accomplish this. A few of them are as follows:
a = [1,2,3,4,5]
2.in? a #=> true
8.in? a #=> false
a.member? 1 #=> true
a.member? 8 #=> false
I have almost same issue with VideoView. I try to play a video (1080*1080) with a Nexus 5 and it works well, but the same video on Galaxy ace 2 give me the Cannot Play Video message.
But I notice that with a lower definition of the video (120x120), it works fine.
So perhaps just a matter of "Size" (and especially with blonde_secretary.3gp video ....)
Getting all elements using var all = document.getElementsByTagName("*"); for (var i=0, max=all.length; i < max; i++);
is ok if you need to check every element but will result in checking or looping repeating elements or text.
Below is a recursion implementation that checks or loop each element of all DOM elements only once and append:
(Credits to @George Reith for his recursion answer here: Map HTML to JSON)
function mapDOMCheck(html_string, json) {
treeObject = {}
dom = new jsdom.JSDOM(html_string) // use jsdom because DOMParser does not provide client-side Window for element access
document = dom.window.document
element = document.querySelector('html')
// Recurse and loop through DOM elements only once
function treeHTML(element, object) {
var nodeList = element.childNodes;
if (nodeList != null) {
if (nodeList.length) {
object[element.nodeName] = []; // IMPT: empty [] array for parent node to push non-text recursivable elements (see below)
for (var i = 0; i < nodeList.length; i++) {
console.log("nodeName", nodeList[i].nodeName);
if (nodeList[i].nodeType == 3) { // if child node is **final base-case** text node
console.log("nodeValue", nodeList[i].nodeValue);
} else { // else
object[element.nodeName].push({}); // push {} into empty [] array where {} for recursivable elements
treeHTML(nodeList[i], object[element.nodeName][object[element.nodeName].length - 1]);
}
}
}
}
}
treeHTML(element, treeObject);
}
Update: In modern browsers you can use the form
attribute to do this.
As far as I know, you cannot do this without javascript.
Here's what the spec says
The elements used to create controls generally appear inside a FORM element, but may also appear outside of a FORM element declaration when they are used to build user interfaces. This is discussed in the section on intrinsic events. Note that controls outside a form cannot be successful controls.
That's my bold
A submit
button is considered a control.
http://www.w3.org/TR/html4/interact/forms.html#h-17.2.1
From the comments
I have a multi tabbed settings area with a button to update all, due to the design of it the button would be outside of the form.
Why not place the input
inside the form, but use CSS to position it elsewhere on the page?
Your approach won't deal with lot of names correctly but...
SELECT CASE
WHEN name LIKE '% %' THEN LEFT(name, Charindex(' ', name) - 1)
ELSE name
END,
CASE
WHEN name LIKE '% %' THEN RIGHT(name, Charindex(' ', Reverse(name)) - 1)

As of Flutter v1.7.8+hotfix.2, the way to go is:
FocusScope.of(context).unfocus()
Comment on PR about that:
Now that #31909 (be75fb3) has landed, you should use
FocusScope.of(context).unfocus()
instead ofFocusScope.of(context).requestFocus(FocusNode())
, sinceFocusNode
s areChangeNotifiers
, and should be disposed properly.

One alternative instead of using hard-coded values could be using range mappings on the the switch statement instead:
private static final int RANGE_5_100 = 1;
private static final int RANGE_101_1000 = 2;
private static final int RANGE_1001_10000 = 3;
public boolean handleRanges(int n) {
int rangeCode = getRangeCode(n);
switch (rangeCode) {
case RANGE_5_100: // doSomething();
case RANGE_101_1000: // doSomething();
case RANGE_1001_10000: // doSomething();
default: // invalid range
}
}
private int getRangeCode(int n) {
if (n >= 5 && n <= 100) {
return RANGE_5_100;
} else if (n >= 101 && n <= 1000) {
return RANGE_101_1000;
} else if (n >= 1001 && n <= 10000) {
return RANGE_1001_10000;
}
return -1;
}
String s1 = "Welcome"; // Does not create a new instance
String s2 = new String("Welcome"); // Creates two objects and one reference variable
You will have to use vendor prefixes to support different browsers and therefore can't use it in shorthand.

I feel that none of the preexisting answers fully identify the answer here, so I'm going to articulate my own perspective. Functionally, the two methods are the same. If the programer is familiar with other languages following C syntax, then they will likely feel more comfortable with the braces, or else if php is the first language that they're learning, they will feel more comfortable with the if
endif
syntax, since it seems closer to regular language.
If you're a really serious programmer and need to get things done fast, then I do believe that the curly brace syntax is superior because it saves time typing
if(/*condition*/){
/*body*/
}
compared to
if(/*condition*/):
/*body*/
endif;
This is especially true with other loops, say, a foreach
where you would end up typing an extra 10 chars. With braces, you just need to type two characters, but for the keyword based syntax you have to type a whole extra keyword for every loop and conditional statement.
I was having multiple date formats into json, and was extracting csv with universal format. I looked multiple places, tried different ways, but at the end I'm able to convert with the following simple code.
private String getDate(String anyDateFormattedString) {
@SuppressWarnings("deprecation")
Date date = new Date(anyDateFormattedString);
SimpleDateFormat dateFormat = new SimpleDateFormat(yourDesiredDateFormat);
String convertedDate = dateFormat.format(date);
return convertedDate;
}
If you're using Angular you can use the following code to do the same.
in component.html
<table id="" datatable [dtOptions]="dtOptions" class="table dataTable">
and in your component.ts
dtOptions: any = {}
this.dtOptions = {
searching: true, //enables the search bar
info: false //disables the entry information
}

I've encountered this today and the accepted answers did not work for me. Here is how I did it.
if( $('#div-id *').length === 0 ) {

My solution checks if there are any elements inside the div so it would still mark the div empty if there is only text inside it.
This error happens when the branch you are switching to, has changes that your current branch doesn't have.
If you are seeing this error when you try to switch to a new branch, then your current branch is probably behind one or more commits. If so, run:
git fetch
You should also remove dependencies which may also conflict with the destination branch.
For example, for iOS developers:
pod deintegrate
then try checking out a branch again.
If the desired branch isn't new you can either cherry pick a commit and fix the conflicts or stash the changes and then fix the conflicts.
1. Git Stash (recommended)
git stash
git checkout <desiredBranch>
git stash apply
2. Cherry pick (more work)
git add <your file>
git commit -m "Your message"
git log
Copy the sha of your commit. Then discard unwanted changes:
git checkout .
git checkout -- .
git clean -f -fd -fx
Make sure your branch is up to date:
git fetch
Then checkout to the desired branch
git checkout <desiredBranch>
Then cherry pick the other commit:
git cherry-pick <theSha>
Now fix the conflict.
git checkout -f branch
Another approach is by using regular expressions.
$fileName = basename($filePath);
$fileNameNoExtension = preg_replace("/\.[^.]+$/", "", $fileName);

Which would you suggest for a new project?
I would suggest neither! Use Spring DAO's JdbcTemplate
together with StoredProcedure
, RowMapper
and RowCallbackHandler
instead.
My own personal experience with Hibernate is that the time saved up-front is more than offset by the endless days you will spend down the line trying to understand and debug issues like unexpected cascading update behaviour.
If you are using a relational DB then the closer your code is to it, the more control you have. Spring's DAO layer allows fine control of the mapping layer, whilst removing the need for boilerplate code. Also, it integrates into Spring's transaction layer which means you can very easily add (via AOP) complicated transactional behaviour without this intruding into your code (of course, you get this with Hibernate too).
I see two problems:
DOUBLE(10) precision definitions need a total number of digits, as well as a total number of digits after the decimal:
DOUBLE(10,8) would make be ten total digits, with 8 allowed after the decimal.
Also, you'll need to specify your id column as a key :
CREATE TABLE transactions(
id int NOT NULL AUTO_INCREMENT,
location varchar(50) NOT NULL,
description varchar(50) NOT NULL,
category varchar(50) NOT NULL,
amount double(10,9) NOT NULL,
type varchar(6) NOT NULL,
notes varchar(512),
receipt int(10),
PRIMARY KEY(id) );
Some details about transposing 4x4 square float (I will discuss 32-bit integer later) matrices with x86 hardware. It's helpful to start here in order to transpose larger square matrices such as 8x8 or 16x16.
_MM_TRANSPOSE4_PS(r0, r1, r2, r3)
is implemented differently by different compilers. GCC and ICC (I have not checked Clang) use unpcklps, unpckhps, unpcklpd, unpckhpd
whereas MSVC uses only shufps
. We can actually combine these two approaches together like this.
t0 = _mm_unpacklo_ps(r0, r1);
t1 = _mm_unpackhi_ps(r0, r1);
t2 = _mm_unpacklo_ps(r2, r3);
t3 = _mm_unpackhi_ps(r2, r3);
r0 = _mm_shuffle_ps(t0,t2, 0x44);
r1 = _mm_shuffle_ps(t0,t2, 0xEE);
r2 = _mm_shuffle_ps(t1,t3, 0x44);
r3 = _mm_shuffle_ps(t1,t3, 0xEE);
One interesting observation is that two shuffles can be converted to one shuffle and two blends (SSE4.1) like this.
t0 = _mm_unpacklo_ps(r0, r1);
t1 = _mm_unpackhi_ps(r0, r1);
t2 = _mm_unpacklo_ps(r2, r3);
t3 = _mm_unpackhi_ps(r2, r3);
v = _mm_shuffle_ps(t0,t2, 0x4E);
r0 = _mm_blend_ps(t0,v, 0xC);
r1 = _mm_blend_ps(t2,v, 0x3);
v = _mm_shuffle_ps(t1,t3, 0x4E);
r2 = _mm_blend_ps(t1,v, 0xC);
r3 = _mm_blend_ps(t3,v, 0x3);
This effectively converted 4 shuffles into 2 shuffles and 4 blends. This uses 2 more instructions than the implementation of GCC, ICC, and MSVC. The advantage is that it reduces port pressure which may have a benefit in some circumstances. Currently all the shuffles and unpacks can go only to one particular port whereas the blends can go to either of two different ports.
I tried using 8 shuffles like MSVC and converting that into 4 shuffles + 8 blends but it did not work. I still had to use 4 unpacks.
I used this same technique for a 8x8 float transpose (see towards the end of that answer). https://stackoverflow.com/a/25627536/2542702. In that answer I still had to use 8 unpacks but I manged to convert the 8 shuffles into 4 shuffles and 8 blends.
For 32-bit integers there is nothing like shufps
(except for 128-bit shuffles with AVX512) so it can only be implemented with unpacks which I don't think can be convert to blends (efficiently). With AVX512 vshufi32x4
acts effectively like shufps
except for 128-bit lanes of 4 integers instead of 32-bit floats so this same technique might be possibly with vshufi32x4
in some cases. With Knights Landing shuffles are four times slower (throughput) than blends.

It is a file ext that some folks used for a while to denote that it was PHP generated HTML. As servers like Apache don't care what you use as a file ext as long as it is mapped to something, you could go ahead and call all your PHP files .jimyBobSmith and it would happily run them. PHTML just happened to be a trend that caught on for a while.
You cannot do so - the browser will not allow this because of security concerns. Although there are workarounds, the fact is that you shouldn't count on this working. The following Stack Overflow questions are relevant here:
In addition to these, the new HTML5 specification states that browsers will need to feed a Windows compatible fakepath into the input type="file"
field, ostensibly for backward compatibility reasons.
So trying to obtain the path is worse then useless in newer browsers - you'll actually get a fake one instead.

Here's a simpler method to add multiple classes via classList
(supported by all modern browsers, as noted in other answers here):
div.classList.add('foo', 'bar'); // add multiple classes
From: https://developer.mozilla.org/en-US/docs/Web/API/Element/classList#Examples
If you have an array of class names to add to an element, you can use the ES6 spread operator to pass them all into classList.add()
via this one-liner:
let classesToAdd = [ 'foo', 'bar', 'baz' ];
div.classList.add(...classesToAdd);
Note that not all browsers support ES6 natively yet, so as with any other ES6 answer you'll probably want to use a transpiler like Babel, or just stick with ES5 and use a solution like @LayZee's above.
You can use below command if you want to print entire line and file name if the occurrence of particular word in current directory you are searching.

I would suggest the use of MySQLi or MySQL PDO for performance and security purposes, but to answer the question:
while($row = mysql_fetch_assoc($result)){
$json[] = $row;
}
echo json_encode($json);
If you switched to MySQLi you could do:
$query = "SELECT * FROM table";
$result = mysqli_query($db, $query);
$json = mysqli_fetch_all ($result, MYSQLI_ASSOC);
echo json_encode($json );

In my case it was because I had opened SmartGit's Log in the respective Git project and Total Commander in the respective project directory. When I closed both I was able to rebase without any problem.
The more I think about it, the more I suspect Total Commander, i.e. Windows having a lock on opened directory the git rebase was trying to something with.
Friendly advice: When you try to fix something, always do one change at a time. ;)
git doc about git revert -m provide a link exactly explain this: https://github.com/git/git/blob/master/Documentation/howto/revert-a-faulty-merge.txt
I found a very good answer here which explains when to use what in simple words:
The basic rule of thumb for which framework to use is how to plan on editing your data in your presentation layer.
Linq-To-Sql - use this framework if you plan on editing a one-to-one relationship of your data in your presentation layer. Meaning you don't plan on combining data from more than one table in any one view or page.
Entity Framework - use this framework if you plan on combining data from more than one table in your view or page. To make this clearer, the above terms are specific to data that will be manipulated in your view or page, not just displayed. This is important to understand.
With the Entity Framework you are able to "merge" tabled data together to present to the presentation layer in an editable form, and then when that form is submitted, EF will know how to update ALL the data from the various tables.
There are probably more accurate reasons to choose EF over L2S, but this would probably be the easiest one to understand. L2S does not have the capability to merge data for view presentation.

using the select cast('1753-1-1' as datetime)

std::weak_ptr
is a very good way to solve the dangling pointer problem. By just using raw pointers it is impossible to know if the referenced data has been deallocated or not. Instead, by letting a std::shared_ptr
manage the data, and supplying std::weak_ptr
to users of the data, the users can check validity of the data by calling expired()
or lock()
.
You could not do this with std::shared_ptr
alone, because all std::shared_ptr
instances share the ownership of the data which is not removed before all instances of std::shared_ptr
are removed. Here is an example of how to check for dangling pointer using lock()
:
#include <iostream>
#include <memory>
int main()
{
// OLD, problem with dangling pointer
// PROBLEM: ref will point to undefined data!
int* ptr = new int(10);
int* ref = ptr;
delete ptr;
// NEW
// SOLUTION: check expired() or lock() to determine if pointer is valid
// empty definition
std::shared_ptr<int> sptr;
// takes ownership of pointer
sptr.reset(new int);
*sptr = 10;
// get pointer to data without taking ownership
std::weak_ptr<int> weak1 = sptr;
// deletes managed object, acquires new pointer
sptr.reset(new int);
*sptr = 5;
// get pointer to new data without taking ownership
std::weak_ptr<int> weak2 = sptr;
// weak1 is expired!
if(auto tmp = weak1.lock())
std::cout << *tmp << '\n';
else
std::cout << "weak1 is expired\n";
// weak2 points to new data (5)
if(auto tmp = weak2.lock())
std::cout << *tmp << '\n';
else
std::cout << "weak2 is expired\n";
}
I wish there were a more elegant solution, like just allowing string type enum
in the language level, but it seems that it is not supported yet. The code below is basically the same idea as other answers, but I think it is shorter and it can be reused. All you have to do is adding a [Description("")]
above each enum
entry and add a class that has 10 lines.
The class:
public static class Extensions
{
public static string ToStringValue(this Enum en)
{
var type = en.GetType();
var memInfo = type.GetMember(en.ToString());
var attributes = memInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false);
var stringValue = ((DescriptionAttribute)attributes[0]).Description;
return stringValue;
}
}
Usage:
enum Country
{
[Description("Deutschland")]
Germany,
[Description("Nippon")]
Japan,
[Description("Italia")]
Italy,
}
static void Main(string[] args)
{
Show(new[] {Country.Germany, Country.Japan, Country.Italy});
void Show(Country[] countries)
{
foreach (var country in countries)
{
Debug.WriteLine(country.ToStringValue());
}
}
}
Create your own confirm box:
<div id="confirmBox">
<div class="message"></div>
<span class="yes">Yes</span>
<span class="no">No</span>
</div>
Create your own confirm()
method:
function doConfirm(msg, yesFn, noFn)
{
var confirmBox = $("#confirmBox");
confirmBox.find(".message").text(msg);
confirmBox.find(".yes,.no").unbind().click(function()
{
confirmBox.hide();
});
confirmBox.find(".yes").click(yesFn);
confirmBox.find(".no").click(noFn);
confirmBox.show();
}
Call it by your code:
doConfirm("Are you sure?", function yes()
{
form.submit();
}, function no()
{
// do nothing
});
You'll need to add CSS to style and position your confirm box appropriately.

The Address property of a cell can get this for you:
MsgBox Cells(1, 1).Address(RowAbsolute:=False, ColumnAbsolute:=False)
returns A1
.
The other way around can be done with the Row
and Column
property of Range
:
MsgBox Range("A1").Row & ", " & Range("A1").Column
returns 1,1
.
Just like with nextSibling and nextElementSibling, just remember that, properties with "element" in their name always returns Element
or null
. Properties without can return any other kind of node.
console.log(document.body.parentNode, "is body's parent node"); // returns <html>
console.log(document.body.parentElement, "is body's parent element"); // returns <html>
var html = document.body.parentElement;
console.log(html.parentNode, "is html's parent node"); // returns document
console.log(html.parentElement, "is html's parent element"); // returns null
I found when using this method that the space between the td elements caused a gap to form in the border, but have no fear...
One way around this:
<tr>
<td>
Example of normal table data
</td>
<td class="end" colspan="/* total number of columns in entire table*/">
/* insert nothing in here */
</td>
</tr>
With the CSS:
td.end{
border:2px solid black;
}
Unrelated to the OP's problem, but my issue was that I'm a noob shell scripter. All the other languages I've used require parentheses to invoke methods, whereas shell doesn't seem to like that.

Simply parsing the JSON and comparing the two objects is not enough because it wouldn't be the exact same object references (but might be the same values).
You need to do a deep equals.
From http://threebit.net/mail-archive/rails-spinoffs/msg06156.html - which seems the use jQuery.
Object.extend(Object, {
deepEquals: function(o1, o2) {
var k1 = Object.keys(o1).sort();
var k2 = Object.keys(o2).sort();
if (k1.length != k2.length) return false;
return k1.zip(k2, function(keyPair) {
if(typeof o1[keyPair[0]] == typeof o2[keyPair[1]] == "object"){
return deepEquals(o1[keyPair[0]], o2[keyPair[1]])
} else {
return o1[keyPair[0]] == o2[keyPair[1]];
}
}).all();
}
});
Usage:
var anObj = JSON.parse(jsonString1);
var anotherObj= JSON.parse(jsonString2);
if (Object.deepEquals(anObj, anotherObj))
...
This does almost everything you want:
f = open('data.txt', 'rb')
while True:
char = f.read(1)
if not char: break
print "{:02x}".format(ord(char)),
With data.txt created like this:
f = open('data.txt', 'wb')
f.write("ab\r\ncd")
f.close()
I get the following output:
61 62 0d 0a 63 64
tl;dr -- 1. You are using poor variable names. 2. You are slicing your hex strings incorrectly. 3. Your code is never going to replace any newlines. You may just want to forget about that feature. You do not quite yet understand the difference between a character, its integer code, and the hex string that represents the integer. They are all different: two are strings and one is an integer, and none of them are equal to each other. 4. For some files, you shouldn't remove newlines.
===
1. Your variable names are horrendous.
That's fine if you never want to ask anybody questions. But since every one needs to ask questions, you need to use descriptive variable names that anyone can understand. Your variable names are only slightly better than these:
fname = 'data.txt'
f = open(fname, 'rb')
xxxyxx = f.read()
xxyxxx = len(xxxyxx)
print "Length of file is", xxyxxx, "bytes. "
yxxxxx = 0
while yxxxxx < xxyxxx:
xyxxxx = hex(ord(xxxyxx[yxxxxx]))
xyxxxx = xyxxxx[-2:]
yxxxxx = yxxxxx + 1
xxxxxy = chr(13) + chr(10)
xxxxyx = str(xxxxxy)
xyxxxxx = str(xyxxxx)
xyxxxxx.replace(xxxxyx, ' ')
print xyxxxxx
That program runs fine, but it is impossible to understand.
2. The hex() function produces strings of different lengths.
For instance,
print hex(61)
print hex(15)
--output:--
0x3d
0xf
And taking the slice [-2:] for each of those strings gives you:
3d
xf
See how you got the 'x' in the second one? The slice:
[-2:]
says to go to the end of the string and back up two characters, then grab the rest of the string. Instead of doing that, take the slice starting 3 characters in from the beginning:
[2:]
3. Your code will never replace any newlines.
Suppose your file has these two consecutive characters:
"\r\n"
Now you read in the first character, "\r", and convert it to an integer, ord("\r"), giving you the integer 13. Now you convert that to a string, hex(13), which gives you the string "0xd"
, and you slice off the first two characters giving you:
"d"
Next, this line in your code:
bndtx.replace(entx, ' ')
tries to find every occurrence of the string "\r\n"
in the string "d"
and replace it. There is never going to be any replacement because the replacement string is two characters long and the string "d"
is one character long.
The replacement won't work for "\r\n"
and "0d"
either. But at least now there is a possibility it could work because both strings have two characters. Let's reduce both strings to a common denominator: ascii codes. The ascii code for "\r" is 13, and the ascii code for "\n" is 10. Now what about the string "0d"
? The ascii code for the character "0"
is 48, and the ascii code for the character "d" is 100. Those strings do not have a single character in common. Even this doesn't work:
x = '0d' + '0a'
x.replace("\r\n", " ")
print x
--output:--
'0d0a'
Nor will this:
x = 'd' + 'a'
x.replace("\r\n", " ")
print x
--output:--
da
The bottom line is: converting a character to an integer then to a hex string does not end up giving you the original character--they are just different strings. So if you do this:
char = "a"
code = ord(char)
hex_str = hex(code)
print char.replace(hex_str, " ")
...you can't expect "a" to be replaced by a space. If you examine the output here:
char = "a"
print repr(char)
code = ord(char)
print repr(code)
hex_str = hex(code)
print repr(hex_str)
print repr(
char.replace(hex_str, " ")
)
--output:--
'a'
97
'0x61'
'a'
You can see that 'a' is a string with one character in it, and '0x61'
is a string with 4 characters in it: '0'
, 'x'
, '6'
, and '1'
, and you can never find a four character string inside a one character string.
4) Removing newlines can corrupt the data.
For some files, you do not want to replace newlines. For instance, if you were reading in a .jpg file, which is a file that contains a bunch of integers representing colors in an image, and some colors in the image happened to be represented by the number 13 followed by the number 10, your code would eliminate those colors from the output.
However, if you are writing a program to read only text files, then replacing newlines is fine. But then, different operating systems use different newlines. You are trying to replace Windows newlines(\r\n), which means your program won't work on files created by a Mac or Linux computer, which use \n for newlines. There are easy ways to solve that, but maybe you don't want to worry about that just yet.
I hope all that's not too confusing.
Please try this, it will help you (Swift 4)
1) Install Reachability via CocoaPods or Carthage: Reachability
2) Import Reachability and Use in Network Class
import Reachability
class Network {
private let internetReachability : Reachability?
var isReachable : Bool = false
init() {
self.internetReachability = Reachability.init()
do{
try self.internetReachability?.startNotifier()
NotificationCenter.default.addObserver(self, selector: #selector(self.handleNetworkChange), name: .reachabilityChanged, object: internetReachability)
}
catch {
print("could not start reachability notifier")
}
}
@objc private func handleNetworkChange(notify: Notification) {
let reachability = notify.object as! Reachability
if reachability.connection != .none {
self.isReachable = true
}
else {
self.isReachable = false
}
print("Internet Connected : \(self.isReachable)") //Print Status of Network Connection
}
}
3) Use like Below where You need.
var networkOBJ = Network()
// Use "networkOBJ.isReachable" for Network Status
print(networkOBJ.isReachable)
It's been a while, but last time I had something similar:
ROLLBACK TRAN
or trying to

what had allready been done free'd everything up so I was able to clear things out and start again.
Use Callable
instead of Thread, then you can call Future#get()
which throws any exception that the Callable threw.
Maybe your solutions works with ints, but It Doesnt work for me with dictionarys.
In one hand, remove() has not worked for me. But maybe it works with basic Types. I guess the code bellow is also the way to remove items from objects list.
In the other hand, 'del' has not worked properly either. In my case, using python 3.6: when I try to delete an element from a list in a 'for' bucle with 'del' command, python changes the index in the process and bucle stops prematurely before time. It only works if You delete element by element in reversed order. In this way you dont change the pending elements array index when you are going through it
Then, Im used:
c = len(list)-1
for element in (reversed(list)):
if condition(element):
del list[c]
c -= 1
print(list)
where 'list' is like [{'key1':value1'},{'key2':value2}, {'key3':value3}, ...]
Also You can do more pythonic using enumerate:
for i, element in enumerate(reversed(list)):
if condition(element):
del list[(i+1)*-1]
print(list)
On latest version of NPM you can just do:
npm install gitAuthor/gitRepo#tag
If the repo is a valid NPM package it will be auto-aliased in package.json as:
{
"NPMPackageName": "gitAuthor/gitRepo#tag"
}
If you could add this to @justingordon 's answer there is no need for manual aliasing now !
Please refer the link from JQuery
http://api.jquery.com/keypress/
It says
The keypress event is sent to an element when the browser registers keyboard input. This is similar to the keydown event, except that modifier and non-printing keys such as Shift, Esc, and delete trigger keydown events but not keypress events. Other differences between the two events may arise depending on platform and browser.
That means you can not use keypress in case of arrows.
Some useful examples:
count files in current dir
/bin/ls -lA | egrep -c '^-'
count dirs in current dir
/bin/ls -lA | egrep -c '^d'
count files and dirs in current dir
/bin/ls -lA | egrep -c '^-|^d'
count files and dirs in in one subdirectory
/bin/ls -lA subdir_name/ | egrep -c '^-|^d'
I have noticed a strange thing (at least in my case) :
When I have tried with
ls
instead/bin/ls
the-A
parameterdo not list implied . and ..
NOT WORK as espected. When I usels
that show ./ and ../ So that result wrong count. SOLUTION :/bin/ls
insteadls
Ok, at that time got it done with the help of a friend and the code looks like this.
Sub Saving()
Dim part1 As String
Dim part2 As String
part1 = Range("C5").Value
part2 = Range("C8").Value
ActiveWorkbook.SaveAs Filename:= _
"C:\-docs\cmat\Desktop\pieteikumi\" & part1 & " " & part2 & ".xlsm", FileFormat:= _
xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False
End Sub
How do I edit this part (FileFormat:= _ xlOpenXMLWorkbookMacroEnabled) for it to save as Excel 97-2013 Workbook, have tried several variations with no success. Thankyou
Seems, that I found the solution, but my idea is flawed. By doing this FileFormat:= _ xlOpenXMLWorkbook, it drops out a popup saying, the you cannot save this workbook as a file without Macro enabled. So, is this impossible?
I find the below RE working fine for Date in the following format;
It can accept year from 2000-2099
Please do not forget to add $ at the end,if not it accept 14-11-201 or 20177
date="13-11-2017"
x=re.search("^([1-9] |1[0-9]| 2[0-9]|3[0-1])(.|-)([1-9] |1[0-2])(.|-|)20[0-9][0-9]$",date)
x.group()
output = '13-11-2017'
You could use one of these for the relative path root:
ActiveWorkbook.Path
ThisWorkbook.Path
App.Path
Starting with Java 5.0 you can specify the type of element in the container:
Collections.<Foo>emptyList()
I concur with the other responses that for cases where you want to return an empty list that stays empty, you should use this approach.
This will work although when embedding PHP in HTML it is better practice to use the following form:
<table>
<?php foreach($array as $key=>$value): ?>
<tr>
<td><?= $key; ?></td>
</tr>
<?php endforeach; ?>
</table>
You can find the doc for the alternative syntax on PHP.net
If you want to add 2px padding around the textRect, just do this:
let insets = UIEdgeInsets(top: -2, left: -2, bottom: -2, right: -2)
label.frame = UIEdgeInsetsInsetRect(textRect, insets)
for i,j in dictionary .items():
if i=='C1':
c=[]
for k in j:
j=k+10
c.append(j)
dictionary .update({i:c})
UPDATE FOR CHROME 58+ (RELEASED 2017-04-19)
As of Chrome 58, the ability to identify the host using only commonName
was removed. Certificates must now use subjectAltName
to identify their host(s). See further discussion here and bug tracker here. In the past, subjectAltName
was used only for multi-host certs so some internal CA tools don't include them.
If your self-signed certs worked fine in the past but suddenly started generating errors in Chrome 58, this is why.
So whatever method you are using to generate your self-signed cert (or cert signed by a self-signed CA), ensure that the server's cert contains a subjectAltName
with the proper DNS
and/or IP
entry/entries, even if it's just for a single host.
For openssl, this means your OpenSSL config (/etc/ssl/openssl.cnf
on Ubuntu) should have something similar to the following for a single host:
[v3_ca] # and/or [v3_req], if you are generating a CSR
subjectAltName = DNS:example.com
or for multiple hosts:
[v3_ca] # and/or [v3_req], if you are generating a CSR
subjectAltName = DNS:example.com, DNS:host1.example.com, DNS:*.host2.example.com, IP:10.1.2.3
In Chrome's cert viewer (which has moved to "Security" tab under F12) you should see it listed under Extensions
as Certificate Subject Alternative Name

Calling C++ Code From Go With SWIG
Here are two ways to pass value from Gradle to use in Java;
android {
buildTypes {
debug {
buildConfigField "int", "FOO", "42"
buildConfigField "String", "FOO_STRING", "\"foo\""
buildConfigField "boolean", "LOG", "true"
}
release {
buildConfigField "int", "FOO", "52"
buildConfigField "String", "FOO_STRING", "\"bar\""
buildConfigField "boolean", "LOG", "false"
}
}
}
You can access them with BuildConfig.FOO
android {
buildTypes {
debug{
resValue "string", "app_name", "My App Name Debug"
}
release {
resValue "string", "app_name", "My App Name"
}
}
}
You can access them in the usual way with @string/app_name
or R.string.app_name

You're not running a module -- you're running subroutines/functions that happen to be stored in modules.
If you put the code in a standalone module and don't specify scope in the definitions of your subroutines/functions, they will be public by default, and callable from anywhere within your application. This means that you can call them with RunCode in a macro, from the class modules of forms/reports, from standalone class modules, or for the functions, from SQL (with some caveats).
Given that you were trying to implement in VBA something that you felt was too complicated for SQL, SQL is the likely context in which you want to execute the code. So, you should just be able to call your function within the SQL statement:
SELECT MyTable.PersonID, MyTable.FirstName, MyTable.LastName, FormatAddress([Address], [City], [State], [Zip], [Country]) As Address
FROM MyTable;
That SQL calls a public function called FormatAddress() that takes as arguments the components of an address and formats them appropriately. It's a trivial example as you likely would not need a VBA function for that purpose, but the point is that this is how you call functions from within a SQL statement.
Subroutines (i.e., code that returns no value) are not callable from within SQL statements.
Else you can get id of process your application runs in:
final static int android.os.Process.myPid()
Returns the identifier of this process, which can be used with killProcess(int) and sendSignal(int, int).
You can't add static methods to a type. You can only add (pseudo-)instance methods to an instance of a type.
The point of the this
modifier is to tell the C# compiler to pass the instance on the left-side of the .
as the first parameter of the static/extension method.
In the case of adding static methods to a type, there is no instance to pass for the first parameter.
