ImmutableMap does not accept null
values whereas Collections.unmodifiableMap()
does. In addition it will never change after construction, while UnmodifiableMap
may. From the JavaDoc:
An immutable, hash-based Map with reliable user-specified iteration order. Does not permit null keys or values.
Unlike Collections.unmodifiableMap(java.util.Map), which is a view of a separate map which can still change, an instance of ImmutableMap contains its own data and will never change. ImmutableMap is convenient for public static final maps ("constant maps") and also lets you easily make a "defensive copy" of a map provided to your class by a caller.
Pure4J supports what you are after, in two ways.
First, it provides an @ImmutableValue
annotation, so that you can annotate a class to say that it is immutable. There is a maven plugin to allow you to check that your code actually is immutable (use of final
etc.).
Second, it provides the persistent collections from Clojure, (with added generics) and ensures that elements added to the collections are immutable. Performance of these is apparently pretty good. Collections are all immutable, but implement java collections interfaces (and generics) for inspection. Mutation returns new collections.
Disclaimer: I'm the developer of this
More information needed for a definitive answer, but this code
myNodeList = (ArrayList<MyNode>)this.getVertices();
will only work if this.getVertices()
returns a (subtype of) List<MyNode>
. If it is a different collection (like your Exception seems to indicate), you want to use
new ArrayList<MyNode>(this.getVertices())
This will work as long as a Collection type is returned by getVertices.
There are no disadvantages of primary keys.
To add just some information to @MrWiggles and @Peter Parker answers, when table doesn't have primary key for example you won't be able to edit data in some applications (they will end up saying sth like cannot edit / delete data without primary key). Postgresql allows multiple NULL values to be in UNIQUE column, PRIMARY KEY doesn't allow NULLs. Also some ORM that generate code may have some problems with tables without primary keys.
UPDATE:
As far as I know it is not possible to replicate tables without primary keys in MSSQL, at least without problems (details).
Not enough rep yet to comment. In response to paka's solution, I found I needed to adjust three items:
Before:
^(([a-zA-Z]{1})|([a-zA-Z]{1}[a-zA-Z]{1})|([a-zA-Z]{1}[0-9]{1})|([0-9]{1}[a-zA-Z]{1})|([a-zA-Z0-9][a-zA-Z0-9-_]{1,61}[a-zA-Z0-9]))\.([a-zA-Z]{2,6}|[a-zA-Z0-9-]{2,30}\.[a-zA-Z]{2,3})$
After:
^(([a-zA-Z]{1})|([a-zA-Z]{1}[a-zA-Z]{1})|([a-zA-Z]{1}[0-9]{1})|([0-9]{1}[a-zA-Z]{1})|([a-zA-Z0-9][-_\.a-zA-Z0-9]{1,61}[a-zA-Z0-9]))\.([a-zA-Z]{2,13}|[a-zA-Z0-9-]{2,30}\.[a-zA-Z]{2,3})$
A simple way would be to use
Math.max(min, Math.min(number, max));
and you can obviously define a function that wraps this:
function clamp(number, min, max) {
return Math.max(min, Math.min(number, max));
}
Originally this answer also added the function above to the global Math
object, but that's a relic from a bygone era so it has been removed (thanks @Aurelio for the suggestion)
In T-SQL stored procedures for input parameters explicit 'in' keyword is not required and for output parameters an explicit 'Output' keyword is required. The query in question can be written as:
CREATE PROCEDURE dept_count
(
-- Add input and output parameters for the stored procedure here
@dept_name varchar(20), --Input parameter
@d_count int OUTPUT -- Output parameter declared with the help of OUTPUT/OUT keyword
)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Statements for procedure here
SELECT @d_count = count(*)
from instructor
where instructor.dept_name=@dept_name
END
GO
and to execute above procedure we can write as:
Declare @dept_name varchar(20), -- Declaring the variable to collect the dept_name
@d_count int -- Declaring the variable to collect the d_count
SET @dept_name = 'Test'
Execute dept_count @dept_name,@d_count output
SELECT @d_count -- "Select" Statement is used to show the output
Note that when using "git log -n 1 [branch_name]" option. -n returns only one line of log but order in which this is returned is not guaranteed. Following is extract from git-log man page

Commit Limiting
Besides specifying a range of commits that should be listed using the special notations explained in the description, additional commit limiting may be applied.
Using more options generally further limits the output (e.g. --since=<date1> limits to commits newer than <date1>, and using it with --grep=<pattern> further limits to commits whose log message has a line that matches <pattern>), unless otherwise noted.
Note that these are applied before commit ordering and formatting options, such as --reverse.
-<number>
-n <number>

I believe that in the book class all \part and \chapter are set to start on a recto page.
from book.cls:
\newcommand\part{%
\if@openright
\cleardoublepage
\else
\clearpage
\fi
\thispagestyle{plain}%
\if@twocolumn
\onecolumn
\@tempswatrue
\else
\@tempswafalse
\fi
\null\vfil
\secdef\@part\@spart}
you should be able to renew that command, and something similar for the \chapter.
A little addition to what's written up there:
First, make sure your destructor is also pure virtual
Second, you may want to inherit virtually (rather than normally) when you do implement, just for good measures.

However, table1 did not have column2 column.
What about the official JDBC 4.0 compatible JDBC driver from Microsoft?
If you are looking the opposite like 1 = A , 2 = B etc, you can use the following code. Please note that I have gone only up to 2 levels as I had to convert divisions in a class to A, B, C etc.
loopvariable = 0
numberofdivisions = 53
while (loopvariable <numberofdivisions):
if(loopvariable<26):
print(chr(65+loopvariable))
loopvariable +=1
if(loopvariable > 26 and loopvariable <53):
print(chr(65)+chr(65+(loopvariable-27)))
find /path/to -regex ".*\.\(jpg\|gif\|png\|jpeg\)" > log
Because (a.y - b.y) is probably less then (a.x - b.x) and in your code the casting is done after the divide operation so the result is an integer so 0.
You should cast to float before the / operation

I prefer using a separate file for ie rules, as described earlier.
<!--[if IE]><link rel="stylesheet" type="text/css" href="ie-style.css"/><![endif]-->
And inside it you can set up rules for different versions of ie using this:
.abc {...} /* ALL MSIE */
*html *.abc {...} /* MSIE 6 */
*:first-child+html .abc {...} /* MSIE 7 */

Debugging by raising exceptions is far easier than squinting through print
log statements, and for most bugs, its generally much faster than opening up an irb debugger like pry
or byebug
. Those tools should not always be your first step.
Exception
then and .inspect
its resultThe fastest way to debug Ruby (especially Rails) code is to raise
an exception along the execution path of your code while calling .inspect
on the method or object (e.g. foo
):
raise foo.inspect
In the above code, raise
triggers an Exception
that halts execution of your code, and returns an error message that conveniently contains .inspect
information about the object/method (i.e. foo
) on the line that you're trying to debug.
This technique is useful for quickly examining an object or method (e.g. is it nil
?) and for immediately confirming whether a line of code is even getting executed at all within a given context.
byebug
or pry
Only after you have information about the state of your codes execution flow should you consider moving to a ruby gem irb debugger like pry
or byebug
where you can delve more deeply into the state of objects within your execution path.
When you are trying to debug a problem, good advice is to always: Read The !@#$ing Error Message (RTFM)
That means reading error messages carefully and completely before acting so that you understand what it's trying to tell you. When you debug, ask the following mental questions, in this order, when reading an error message:
nil
?) In the stack trace pay particular attention to lines of code that come from your project (e.g. lines starting with app/...
if you are using Rails). 99% of the time the problem is with your own code.
To illustrate why interpreting in this order is important...
You execute code that at some point executes as such:
@foo = Foo.new
...
@foo.bar
and you get an error that states:
undefined method "bar" for Nil:nilClass
Beginners see this error and think the problem is that the method bar
is undefined. It's not. In this error the real part that matters is:
for Nil:nilClass
for Nil:nilClass
means that @foo
is Nil! @foo
is not a Foo
instance variable! You have an object that is Nil
. When you see this error, it's simply ruby trying to tell you that the method bar
doesn't exist for objects of the class Nil
. (well duh! since we are trying to use a method for an object of the class Foo
not Nil
).
Unfortunately, due to how this error is written (undefined method "bar" for Nil:nilClass
) its easy to get tricked into thinking this error has to do with bar
being undefined
. When not read carefully this error causes beginners to mistakenly go digging into the details of the bar
method on Foo
, entirely missing the part of the error that hints that the object is of the wrong class (in this case: nil). It's a mistake that's easily avoided by reading error messages in their entirety.
Summary:
Always carefully read the entire error message before beginning any debugging. That means: Always check the class type of an object in an error message first, then its methods, before you begin sleuthing into any stacktrace or line of code where you think the error may be occurring. Those 5 seconds can save you 5 hours of frustration.
tl;dr: Don't squint at print logs: raise exceptions or use an irb debugger instead. Avoid rabbit holes by reading errors carefully before debugging.
You cannot do new T()
due to type erasure. The default constructor can only be
public Navigation() { this("", "", null); }
You can create other constructors to provide default values for trigger and description. You need an concrete object of T

You can use the datedif function to find out difference in days.
=DATEDIF(A1,TODAY(),"d")
Quote from excel.datedif.com
The mysterious datedif function in Microsoft Excel
The Datedif function is used to calculate interval between two dates in days, months or years.
This function is available in all versions of Excel but is not documented. It is not even listed in the "Insert Function" dialog box. Hence it must be typed manually in the formula box. Syntax
DATEDIF( start_date, end_date, interval_unit )
start_date from date end_date to date (must be after start_date) interval_unit Unit to be used for output interval Values for interval_unit
interval_unit Description
D Number of days
M Number of complete months
Y Number of complete years
YD Number of days excluding years
MD Number of days excluding months and years
YM Number of months excluding years
Error Description
#NUM! The end_date is later than (greater than) the start_date or interval_unit has an invalid value. #VALUE! end_date or start_date is invalid.
In your .eslintignore file add the following value:
**/__tests__/
This should ignore all instances of the __tests__ directory and their children.
This is an old question, but what worked for me now (in 2019) is:
python -m unittest *_test.py
All my test files are in the same folder as the source files and they end with _test
.
String input = "some input string";
int hashCode = input.hashCode();
System.out.println("input hash code = " + hashCode);
An example usage:
>>> s = 'Hello world'
>>> t = buffer(s, 6, 5)
>>> t
<read-only buffer for 0x10064a4b0, size 5, offset 6 at 0x100634ab0>
>>> print t
world
The buffer in this case is a sub-string, starting at position 6 with length 5, and it doesn't take extra storage space - it references a slice of the string.
This isn't very useful for short strings like this, but it can be necessary when using large amounts of data. This example uses a mutable bytearray
:
>>> s = bytearray(1000000) # a million zeroed bytes
>>> t = buffer(s, 1) # slice cuts off the first byte
>>> s[1] = 5 # set the second element in s
>>> t[0] # which is now also the first element in t!
'\x05'
This can be very helpful if you want to have more than one view on the data and don't want to (or can't) hold multiple copies in memory.
Note that buffer
has been replaced by the better named memoryview
in Python 3, though you can use either in Python 2.7.
Note also that you can't implement a buffer interface for your own objects without delving into the C API, i.e. you can't do it in pure Python.
Underscore and lodash each have a convenient isEmpty()
function, if you don't mind adding an extra library.
_.isEmpty({});
I encountered this error with the Eclipse 4.10 installer. We had failed to complete the install correctly due to platform security settings and attempted to uninstall but had to do it by hand since no uninstaller was introduced during the failed install. We suspected this corrupted the end result - even after re-installing.
The solution was to use the JVM to launch Eclipse and bypass the launcher executable entirely. The following command successfully launches Eclipse 4.10 (some parameters will change based on the version of Eclipse):
%JDK190%\bin\javaw.exe -jar C:\<fully_qualified_path_to_eclipse>\Eclipse410\plugins\org.eclipse.equinox.launcher_1.5.200.v20180922-1751.jar -clean -showsplash
After using this command/shortcut to launch Eclipse we had no further errors with Eclipse itself but we weren't able to use the EXE launcher in the future. Even after a year of using this version, the launcher continues to display this same error.
To be clear, you'll have to modify your javaw.exe
command to match your system specifications on MS Windows.

may work in FF. (Shows up the VERY FIRST 300 characters from the VERY beginning of source-text, mostly doctype-defs.)
BUT be aware, that the normal "Save As"-Dialog of FF MIGHT NOT save the current state of the page, rather the originallly loaded X/h/tml-source-text !! (a POST-up of ss to some temp-file and redirect to that might deliver a saveable source-text WITH the changes/edits prior made to it.)
Although FF surprises by good recovery on "back" and a NICE inclusion of states/values on "Save (as) ..." for input-like FIELDS, textarea etc. , not on elements in contenteditable/ designMode...

When you perform a boolean comparison between two vectors in R, the "expectation" is that both vectors are of the same length, so that R can compare each corresponding element in turn.
R has a much loved (or hated) feature called recycling, whereby in many circumstances if you try to do something where R would normally expect objects to be of the same length, it will automatically extend, or recycle, the shorter object to force both objects to be of the same length.
If the longer object is a multiple of the shorter, this amounts to simply repeating the shorter object several times. Oftentimes R programmers will take advantage of this to do things more compactly and with less typing.
But if they are not multiples, R will worry that you may have made a mistake, and perhaps didn't mean to perform that comparison, hence the warning.
Explore yourself with the following code:
> x <- 1:3
> y <- c(1,2,4)
> x == y
[1] TRUE TRUE FALSE
> y1 <- c(y,y)
> x == y1
[1] TRUE TRUE FALSE TRUE TRUE FALSE
> y2 <- c(y,2)
> x == y2
[1] TRUE TRUE FALSE FALSE
Warning message:
In x == y2 :
longer object length is not a multiple of shorter object length
If you perhaps also want to eliminate all of the duplicates and keep only a single one of each
Change the formula =COUNTIF(A:A,A2)
to =COUNIF($A$2:A2,A2)
and drag the formula down.
Then autofilter for anything greater than 1 and you can delete them.
Have a blank full-screen scene
Add a scroll view. Control-drag from the scroll view to the base view, add left-right-top-bottom, all zero.
Add a stack view in the scroll view. Control-drag from the stack view to the scroll view, add left-right-top-bottom, all zero.
Put two or three labels inside the stack view.
For clarity, make the background color of the label red. Set the label height to 100.
Now set the width of each UILabel:
Surprisingly, control-drag from the UILabel
to the scroll view, not to the stack view, and select equal widths.
To repeat:
It's that simple. That's the secret.
Secret tip - Apple bug:
It will not work with only one item! Add a few labels to make the demo work.
You're done.
Tip: You must add a height to every new item. Every item in any scrolling stack view must have either an intrinsic size (such as a label) or add an explicit height constraint.
The alternative approach:
In the above: surprisingly, set the widths of the UILabels to the width of the scroll view (not the stack view).
Alternately...
So you have two options:

To be clear, do ONE of those methods, do NOT do both.

I'd suggest you decouple the test method name from your test data set. I would model a DataLoaderFactory class which loads/caches the sets of test data from your resources, and then in your test case cam call some interface method which returns a set of test data for the test case. Having the test data tied to the test method name assumes the test data can only be used once, where in most case i'd suggest that the same test data in uses in multiple tests to verify various aspects of your business logic.
With Java 8 you can simply convert your list to a stream allowing you to write:
import java.util.List;
import java.util.stream.Collectors;
List<Sample> list = new ArrayList<Sample>();
List<Sample> result = list.stream()
.filter(a -> Objects.equals(a.value3, "three"))
.collect(Collectors.toList());
Note that
a -> Objects.equals(a.value3, "three")
is a lambda expressionresult
is a List
with a Sample
typelist.parallelStream()
instead of list.stream()
(read this)If you can't use Java 8, you can use Apache Commons library and write:
import org.apache.commons.collections.CollectionUtils;
import org.apache.commons.collections.Predicate;
Collection result = CollectionUtils.select(list, new Predicate() {
public boolean evaluate(Object a) {
return Objects.equals(((Sample) a).value3, "three");
}
});
// If you need the results as a typed array:
Sample[] resultTyped = (Sample[]) result.toArray(new Sample[result.size()]);
Note that:
Object
to Sample
at each iterationSample[]
, you need extra code (as shown in my sample)Bonus: A nice blog article talking about how to find element in list.
Update December 8th, 2015 According to Google Support using the
googledrive.com/host/ID
method will be turned off on Aug 31st, 2016.
I just ran into this issue.
The trick is to treat your Google Drive folder like a web host.
Update April 1st, 2015
Google Drive has changed and there's a simple way to direct link to your drive. I left my previous answers below for reference but to here's an updated answer.
https://googledrive.com/host/<folder UUID>/
https://googledrive.com/host/<folder UUID>/<file name>
Which is intended functionality by Google
new Google Drive Link.
All you have to do is simple get the host URL for a publicly shared drive folder. To do this, you can upload a plain HTML file and preview it in Google Drive to find your host URL.
Here are the steps:
[edit]
I forgot to add. If you use subfolders to organize your files, you simple use the folder name as you would expect in a URL hierarchy.
https://googledrive.com/host/<your public folders id string>/images/my-image.png
What I was looking to do
I created a custom Debian image with Virtual Box for Vagrant. I wanted to share this ".box" file with colleagues so they could put the direct link into their Vagrantfile.
In the end, I needed a direct link to the actual file.
Google Drive problem
If you set the file permissions to be publicly available and create/generate a direct access link by using something like the gdocs2direct tool or just crafting the link yourself:
https://docs.google.com/uc?export=download&id=<your file id>
You will get a cookie based verification code and prompt "Google could not scan this file" prompt, which won't work for things such as wget or Vagrantfile configs.
The code that it generates is a simple code that appends GET query variable ...&confirm=###
to the string, but it's per user specific, so it's not like you can copy/paste that query variable for others.
But if you use the above "Web page hosting" method, you can get around that prompt.
I hope that helps!
1) for example HTML code:
<ul>
<li>
<a href="#">firstlink</a>
<span><a href="#">second link</a>
</li>
</ul>
and css rules:
1) ul li a {color:red;}
2) ul > li > a {color:blue;}
">" - symbol mean that that will be searching only child selector (parentTag > childTag)
so first css rule will apply to all links (first and second) and second rule will apply anly to first link
2) As for efficiency - I think second will be more fast - as in case with JavaScript selectors. This rule read from right to left, this mean that when rule will parse by browser, it get all links on page: - in first case it will find all parent elements for each link on page and filter all links where exist parent tags "ul" and "li" - in second case it will check only parent node of link if it is "li" tag then -> check if parent tag of "li" is "ul"
some thing like this. Hope I describe all properly for you
In order an element to appear in front of another you have to give higher z-index to the front element, and lower z-index to the back element, also you should indicate position: absolute/fixed...
Example:
<div style="z-index:100; position: fixed;">Hello</div>
<div style="z-index: -1;">World</div>
You create handler in background thread this way
private void createHandler() {
Thread thread = new Thread() {
public void run() {
Looper.prepare();
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
// Do Work
handler.removeCallbacks(this);
Looper.myLooper().quit();
}
}, 2000);
Looper.loop();
}
};
thread.start();
}
Use ProgressDialog
ProgressDialog.show(Context context, CharSequence title, CharSequence message);
However this is considered as an anti pattern today (2013): http://www.youtube.com/watch?v=pEGWcMTxs3I
Please make sure that you are using the same version of jquery-ui 'js' and 'css' files. Sometimes that could be a problem.
Comment from DanT fixed this for me, matplotlib with pycharm on linux with the GTKagg backend. Upon importing matplotlib I would get the following error:
>>> import matplotlib as mpl
Backend GTKAgg is interactive backend. Turning interactive mode on.
Failed to enable GUI event loop integration for 'gtk'
When plotting something like so:
from matplotlib import pyplot as plt
plt.figure()
plt.plot(1,2)
plt.show()
A figure screen would pop up but no charts appear. using:
plt.show(block=True)
displays the graphic correctly.
If your CPU is spiking to 100% and staying there, it's quite likely that you either have a deadlock scenario or an infinite loop. A profiler seems like a good choice for finding an infinite loop. Deadlocks are much more difficult to track down, however.
This error appears when you wish to run a software which require the Microsoft Visual C++ Redistributable 2012. Download it fromMicrosoft website as x86 or x64 edition. Depending on the software you wish to install you need to install either the 32 bit or the 64 bit version. Visit the following link: http://www.microsoft.com/en-us/download/details.aspx?id=30679#
To set/remove multiple query params at once I've ended up with the methods below as part of my global mixins (this
points to vue component):
setQuery(query){
let obj = Object.assign({}, this.$route.query);
Object.keys(query).forEach(key => {
let value = query[key];
if(value){
obj[key] = value
} else {
delete obj[key]
}
})
this.$router.replace({
...this.$router.currentRoute,
query: obj
})
},
removeQuery(queryNameArray){
let obj = {}
queryNameArray.forEach(key => {
obj[key] = null
})
this.setQuery(obj)
},
not get the question exactly as it is too simple :
ExampleFragment fragment = (ExampleFragment) getFragmentManager().findFragmentById(R.id.example_fragment);
fragment.<specific_function_name>();
Update: For those who are using Kotlin
var fragment = supportFragmentManager.findFragmentById(R.id.frameLayoutCW) as WebViewFragment
fragment.callAboutUsActivity()
The above solution works perfectly. I prefer to choose Web API option while selecting the project template as shown in the picture below
Note: The solution works with Visual Studio 2013 or higher. The original question was asked in 2012 and it is 2016, therefore adding a solution Visual Studio 2013 or higher.
you can use /<code>([\s\S]*)<\/code>/msU
this catch NEWLINES too!
If the order of your integers is not required, and if there are only unique values
you can also use NSIndexSet or NSMutableIndexSet You will be able to easily add and remove integers, or check if your array contains an integer with
- (void)addIndex:(NSUInteger)index
- (void)removeIndex:(NSUInteger)index
- (BOOL)containsIndexes:(NSIndexSet *)indexSet
Check the documentation for more info.
To handle SSL urls the method onReceivedSslError() from the WebViewClient class, This is an example:
webview.setWebViewClient(new WebViewClient() {
...
...
...
@Override
public void onReceivedSslError(WebView view, final SslErrorHandler handler, SslError error) {
String message = "SSL Certificate error.";
switch (error.getPrimaryError()) {
case SslError.SSL_UNTRUSTED:
message = "The certificate authority is not trusted.";
break;
case SslError.SSL_EXPIRED:
message = "The certificate has expired.";
break;
case SslError.SSL_IDMISMATCH:
message = "The certificate Hostname mismatch.";
break;
case SslError.SSL_NOTYETVALID:
message = "The certificate is not yet valid.";
break;
}
message += "\"SSL Certificate Error\" Do you want to continue anyway?.. YES";
handler.proceed();
}
});
You can check my complete example here: https://github.com/Jorgesys/Android-WebView-Logging
Use:
$filelist = @("11", "1", "2")
$filelist | sort @{expression={[int]$_}} | % {$newName = [string]([int]$_ + 1)}
New-Item $newName -ItemType Directory
An easy way would be to use $toLower as below.
db.users.aggregate([
{
$project: {
name: { $toLower: "$name" }
}
},
{
$match: {
name: the_name_to_search
}
}
])
You can use Character.isDigit(char ch) method or you can also use regular expression.
Below is the snippet:
public class CheckDigit {
private static Scanner input;
public static void main(String[] args) {
System.out.print("Enter a String:");
input = new Scanner(System.in);
String str = input.nextLine();
if (CheckString(str)) {
System.out.println(str + " is numeric");
} else {
System.out.println(str +" is not numeric");
}
}
public static boolean CheckString(String str) {
for (char c : str.toCharArray()) {
if (!Character.isDigit(c))
return false;
}
return true;
}
}
If this is your app, if you connect the device to your computer, you can use the "Devices" option on Xcode's "Window" menu and then download the app's data container to your computer. Just select your app from the list of installed apps, and click on the "gear" icon and choose "Download Container".
Once you've downloaded it, right click on the file in the Finder and choose "Show Package Contents".
There is already an ISO standard for this; no need to invent your own scheme:
http://en.wikipedia.org/wiki/ISO_5218
Per the standard, the column should be called "Sex" and the 'closest' data type would be tinyint with a CHECK constraint or lookup table as appropriate.
While a bit more work, if you want a high performance native solution there are some HTML5 functions you can use.
If you can get your data into a Blob
, then you can use the FileReader.readAsDataURL() function to get a data://
URL and chop off the front of it to get at the base64 data.
You may have to do further processing however to urldecode the data, as I'm not sure whether +
characters are escaped or not for the data://
URL, but this should be pretty trivial.
TL;DR:
The ActionListener
s (there can be multiple) execute in the order they were registered BEFORE the action
Long Answer:
A business action
typically invokes an EJB service and if necessary also sets the final result and/or navigates to a different view
if that is not what you are doing an actionListener
is more appropriate i.e. for when the user interacts with the components, such as h:commandButton
or h:link
they can be handled by passing the name of the managed bean method in actionListener
attribute of a UI Component or to implement an ActionListener
interface and pass the implementation class name to actionListener
attribute of a UI Component.
just do this , you need to remove char other than "numeric" and "." form your string will do work for you
yourString = yourString.replace ( /[^\d.]/g, '' );
your final code will be
str1 = "test123.00".replace ( /[^\d.]/g, '' );
str2 = "yes50.00".replace ( /[^\d.]/g, '' );
total = parseInt(str1, 10) + parseInt(str2, 10);
alert(total);
I am doing similar thing to compile all the c files in a directory.
for iterating files in different directory try this.
set codedirectory=C:\Users\code
for /r %codedirectory% %%i in (*.c) do
( some GCC commands )
Simple way to access the Url Try this Code
$.ajax({
type: "POST",
url: '/Controller/Search',
data: "{queryString:'" + searchVal + "'}",
contentType: "application/json; charset=utf-8",
dataType: "html",
success: function (data) {
alert("here" + data.d.toString());
});
I found this useful to read from a specific column and row:
FileStream stream = File.Open(@"C:\Users\Desktop\ExcelDataReader.xlsx", FileMode.Open, FileAccess.Read);
IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
DataSet result = excelReader.AsDataSet();
excelReader.IsFirstRowAsColumnNames = true;
DataTable dt = result.Tables[0];
string text = dt.Rows[1][0].ToString();
Use either
$ gem list --no-version | xargs gem uninstall -ax
or
$ sudo gem list --no-version | xargs sudo gem uninstall -ax
Depending on what you want, you may need to execute both, because "gem list" and "sudo gem list" provide independent lists.
Do not mix a normal "gem list" with a sudo-ed "gem uninstall" nor the other way around otherwise you may end up uninstalling sudo-installed gems (former) or getting a lot of errors (latter).
Remove unwanted activation of some of the plugins at start-up by going to windows-->preference-->General-->Startup and shutdown. Also make sure you don't use those plugins in any of your views
Eclipse is not a word processor. Better to disable the spell check. Disabling spell check will reduce the eclipse burden by going to Windows-->Preference-->General-->Editors --> Text Editors-->Spelling
When eclipse builds the project, it will delete all output folders and rebuild classes built by other compilers. We can disable such features, as deleting the output folders and rebuilding will take sometime. Goto Windows-->Preference-->Java-->Compiler-->Building
Disabling label decorations which is of less use for you, will also help you to gain some performance . Goto Windows-->Preference-->General-->Appearance-->Label Decorations
Close unwanted projects and use working set option to move from one group of project to another smoothly.
You could also disable Eclipse automatic building, if it is not needed for you. Goto Project-->Build Automatically (uncheck it)
Do not keep lot of tabs opened in the editor. Better to have around 20 tabs . Regularly close the unused tabs. To open resource we can always use ctrl+shift+R and ctrl+shift+T (java resource) instead of opening lot of tabs
Disable unwanted plugins. Full J2EE eclipse version has an option to disable/uninstall plugins. Goto Help-->Software Updates-->Manage Configuration. Right click on any installed plugin to get disable option. If this option is not available then enable Classic Update by going to Windows-->Preference-->Capabilty and check classic update. Now the manage configuration option should be available in help menu
I think you have a conceptual problem here. To say "I tried set height:100% on iframe, the result is quite close but the iframe tried to fill the whole page", well, when has "100%" not been equal to "whole"?
You have asked the iframe to fill the entire height of its container (which is the body) but unfortunately it has a block level sibling in the <div> above which you've asked to be 30px big. So the parent container total is now being asked to size to 100% + 30px > 100%! Hence scrollbars.
What I think you mean is that you would like the iframe to consume what's left like frames and table cells can, i.e. height="*". IIRC this doesn't exist.
Unfortunately to the best of my knowledge there is no way to effectively mix/calculate/subtract absolute and relative units either, so I think you're reduced to two options:
Absolutely position your div, which will take it out of the container so the iframe alone will consume it's containers height. This leaves you with all manner of other problems though, but perhaps for what you're doing opacity or alignment would be ok.
Alternatively you need to specify a % height for the div and reduce the height of the iframe by that much. If the absolute height is really that important you'll need to apply that to a child element of the div instead.
Yes, let's use Select
as an example
sample code: Columns("A").select
How to loop through Columns:
Method 1: (You can use index to replace the Excel Address)
For i = 1 to 100
Columns(i).Select
next i
Method 2: (Using the address)
For i = 1 To 100
Columns(Columns(i).Address).Select
Next i
EDIT: Strip the Column for OP
columnString = Replace(Split(Columns(27).Address, ":")(0), "$", "")
e.g. you want to get the 27th Column --> AA, you can get it this way
if you're receiving the error in parameter, so keep any
or any[]
type of input like below
getOptionLabel={(option: any) => option!.name}
<Autocomplete
options={tests}
getOptionLabel={(option: any) => option!.name}
....
/>
I would recommend separating out all of the foreign-key constraints from your CREATE TABLE
statements. Create all the tables first without FK constraints, and then create all the FK constraints once you have created the tables.
You can add an FK constraint to a table using SQL like the following:
ALTER TABLE orders ADD CONSTRAINT orders_FK
FOREIGN KEY (m_p_unique_id) REFERENCES library (m_p_unique_id);
In particular, your formats
and library
tables both have foreign-key constraints on one another. The two CREATE TABLE
statements to create these two tables can never run successfully, as each will only work when the other table has already been created.
Separating out the constraint creation allows you to create tables with FK constraints on one another. Also, if you have an error with a constraint, only that constraint fails to be created. At present, because you have errors in the constraints in your CREATE TABLE
statements, then entire table creation fails and you get various knock-on errors because FK constraints may depend on these tables that failed to create.
The jQuery plugin hoverIntent http://cherne.net/brian/resources/jquery.hoverIntent.html goes much further than the naive approaches listed here. While they certainly work, they might not necessarily behave how users expect.
The strongest reason to use hoverIntent is the timeout feature. It allows you to do things like prevent a menu from closing because a user drags their mouse slightly too far to the right or left before they click the item they want. It also provides capabilities for not activating hover events in a barrage and waits for focused hovering.
Usage example:
var config = {
sensitivity: 3, // number = sensitivity threshold (must be 1 or higher)
interval: 200, // number = milliseconds for onMouseOver polling interval
over: makeTall, // function = onMouseOver callback (REQUIRED)
timeout: 500, // number = milliseconds delay before onMouseOut
out: makeShort // function = onMouseOut callback (REQUIRED)
};
$("#demo3 li").hoverIntent( config )
Further explaination of this can be found on https://stackoverflow.com/a/1089381/37055
Chances are that without full access to this server (due to being a hosted account) you are going to have problems. I would go so far as to say that I think it is a fruitless endeavor--they have to lock servers down in hosted environments for good reason.
Call your hosting company and make the request to them to install it, but don't expect a good response--they typically won't install very custom items for single users unless there is a really good reason (bug fixes for example).
Lastly, depending on how familiar you are with server administration and what you are paying for server hosting now consider something like http://www.slicehost.com. $20 a month will get you a low grade web server (256 ram) and you can install anything you want. However, if you are running multiple sites or have heavy load the cost will go up as you need larger servers.

Construct a SimpleDateFormat with the mask, and then call: SimpleDateFormat.parse(String s, ParsePosition p)
You can either have the newly inserted ID being output to the SSMS console like this:
INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')
You can use this also from e.g. C#, when you need to get the ID back to your calling app - just execute the SQL query with .ExecuteScalar()
(instead of .ExecuteNonQuery()
) to read the resulting ID
back.
Or if you need to capture the newly inserted ID
inside T-SQL (e.g. for later further processing), you need to create a table variable:
DECLARE @OutputTbl TABLE (ID INT)
INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID INTO @OutputTbl(ID)
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')
This way, you can put multiple values into @OutputTbl
and do further processing on those. You could also use a "regular" temporary table (#temp
) or even a "real" persistent table as your "output target" here.
I had the same problem. I realised than in X-Code Manual

How to find elements by class
I'm having trouble parsing html elements with "class" attribute using Beautifulsoup.
You can easily find by one class, but if you want to find by the intersection of two classes, it's a little more difficult,
From the documentation (emphasis added):
If you want to search for tags that match two or more CSS classes, you should use a CSS selector:
css_soup.select("p.strikeout.body") # [<p class="body strikeout"></p>]
To be clear, this selects only the p tags that are both strikeout and body class.
To find for the intersection of any in a set of classes (not the intersection, but the union), you can give a list to the class_
keyword argument (as of 4.1.2):
soup = BeautifulSoup(sdata)
class_list = ["stylelistrow"] # can add any other classes to this list.
# will find any divs with any names in class_list:
mydivs = soup.find_all('div', class_=class_list)
Also note that findAll has been renamed from the camelCase to the more Pythonic find_all
.
Technically, this is the same answer as @Sujee. It also depends on your version of Oracle as to whether it works. (I think this syntax was introduced in Oracle 12??)
SELECT *
FROM table
ORDER BY value DESC, date_column ASC
FETCH first 1 rows only;
As I say, if you look under the bonnet, I think this code is unpacked internally by the Oracle Optimizer to read like @Sujee's. However, I'm a sucker for pretty coding, and nesting select
statements without a good reason does not qualify as beautiful!! :-P
Use curly braces around the variable name:
`tail -1 ${filepath}_newstap.sh`
Just do like below, it helped me after doing like this.
To load existing Eclipse projects in the IDE, you need to import them into the Eclipse workspace.
Look at this below link for reference. https://www.microfocus.com/documentation/enterprise-developer/ed30/Eclipse/GUID-773A19C7-98B2-442D-9D36-240E20E3F2CE.html
While arguably being less clear this method is faster by roughly a factor of roughly 3.5 (At least on the box I used to test)
$foo = array(
1 => "Value1",
2 => "Value2",
10 => "Value10"
);
while($bar = each($foo)){
echo $bar[0] . " => " . $bar[1];
}
I would imagine that this is due to the fact the foreach copies the entire array before iterating over it.
The code overlooks calling the function move_uploaded_file() which would check whether the indicated file is valid for uploading.
You may wish to review a simple example at:
In getUserById
you shouldn't create a new object (user1) which isn't used. Just assign it to the already (but null) initialized user
. Otherwise Hibernate.initialize(user);
is actually Hibernate.initialize(null);
Here's the new getUserById
(I haven't tested this ;)):
public User getUserById(Long user_id) {
Session session = null;
Object user = null;
try {
session = HibernateUtil.getSessionFactory().openSession();
user = (User)session.load(User.class, user_id);
Hibernate.initialize(user);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (session != null && session.isOpen()) {
session.close();
}
}
return user;
}
You can specialize your templates based on what's passed into their parameters like this:
template <> void foo<animal> {
}
Note that this creates an entirely new function based on the type that's passed as T
. This is usually preferable as it reduces clutter and is essentially the reason we have templates in the first place.
Why reinvent the wheel? Use Commons Collections:
CollectionUtils.intersection(java.util.Collection a, java.util.Collection b)
I had the same problem, I had the package and class named the same. I renamed the class, then clean and build. Then I set the main class in the "run" under the properties of the project. I works now.
First, use git log
to see the log, pick the commit you want, note down the sha1 hash that is used to identify the commit. Next, run git checkout hash
. After you are done, git checkout original_branch
. This has the advantage of not moving the HEAD, it simply switches the working copy to a specific commit.
Try this:
string selected = this.ComboBox.GetItemText(this.ComboBox.SelectedItem);
MessageBox.Show(selected);
This fixed it for me:
$ sudo chmod -R 755 /usr/local/share/zsh/site-functions
Credit: a post on zsh mailing list
EDIT: As pointed out by @biocyberman in the comments. You may need to update the owner of site-functions
as well:
$ sudo chown -R root:root /usr/local/share/zsh/site-functions
On my machine (OSX 10.9), I do not need to do this but YMMV.
EDIT2: On OSX 10.11, only this worked:
$ sudo chmod -R 755 /usr/local/share/zsh
$ sudo chown -R root:staff /usr/local/share/zsh
Also user:staff is the correct default permission on OSX.
Use
Comparator<File> comparator = Comparator.comparing(File::lastModified);
Collections.sort(list, comparator.reversed());
Then
.forEach(item -> item.delete());
\B
is not \b
e.g. negative \b
pass-key
here is no word boundary beside -
so it matches \B
in your first example there are word boundary beside cat so it matches \b
similar rules apply for others too. \W
is negative of \w
\UPPER CASE
is negative of \LOWER CASE
You can use dataSrc :
Here is a typical example of datatables.net
var table = $('#example').DataTable( {
"ajax": {
"type" : "GET",
"url" : "ajax.php",
"dataSrc": function ( json ) {
//Make your callback here.
alert("Done!");
return json.data;
}
},
"columns": [
{ "data": "name" },
{ "data": "position" },
{ "data": "office" },
{ "data": "extn" },
{ "data": "start_date" },
{ "data": "salary" }
]
} );
Try this query:
SELECT *
FROM table
WHERE MONTH(FROM_UNIXTIME(columnName))= MONTH(CURDATE())
When you have everything #included, an unresolved external symbol is often a missing * or & in the declaration or definition of a function.
One important thing to note, if you have ANSI on sql_mode:
Equivalent to REAL_AS_FLOAT, PIPES_AS_CONCAT, ANSI_QUOTES, IGNORE_SPACE, and (as of MySQL 5.7.5) ONLY_FULL_GROUP_BY.
See https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html#sqlmode_ansi
You are not creating datetime index properly,
format = '%Y-%m-%d %H:%M:%S'
df['Datetime'] = pd.to_datetime(df['date'] + ' ' + df['time'], format=format)
df = df.set_index(pd.DatetimeIndex(df['Datetime']))
In the "Understanding Crashes and Crash Logs" session 414 of the 2018 WWDC they show the following way using DispatchQueues with sync.
In swift 4 should be something like the following:
class ImageCache {
private let queue = DispatchQueue(label: "sync queue")
private var storage: [String: UIImage] = [:]
public subscript(key: String) -> UIImage? {
get {
return queue.sync {
return storage[key]
}
}
set {
queue.sync {
storage[key] = newValue
}
}
}
}
Anyway you can also make reads faster using concurrent queues with barriers. Sync and async reads are performed concurrently and writing a new value waits for previous operations to finish.
class ImageCache {
private let queue = DispatchQueue(label: "with barriers", attributes: .concurrent)
private var storage: [String: UIImage] = [:]
func get(_ key: String) -> UIImage? {
return queue.sync { [weak self] in
guard let self = self else { return nil }
return self.storage[key]
}
}
func set(_ image: UIImage, for key: String) {
queue.async(flags: .barrier) { [weak self] in
guard let self = self else { return }
self.storage[key] = image
}
}
}

You can add a parameter in the query like @emailadd to be added in the aspx.cs file where the Stored Procedure is called with cmd.Parameter.AddWithValue.
The trick is that the @emailadd parameter doesn't exist in the table design of the select query, but being added and inserted in the table.

Swift version:

let layer: AVPlayerLayer = AVPlayerLayer(player: player)
layer.backgroundColor = UIColor.white.cgColor
layer.frame = CGRect(x: 0, y: 0, width: 300, height: 300)
layer.videoGravity = .resizeAspectFill
self.view.layer.addSublayer(layer)

For a use case like this, it may be useful to use a string constant so it can be marshaled into a JSON string. In the following example, []Base{A,C,G,T}
would get marshaled to ["adenine","cytosine","guanine","thymine"]
.
type Base string
const (
A Base = "adenine"
C = "cytosine"
G = "guanine"
T = "thymine"
)
When using iota
, the values get marshaled into integers. In the following example, []Base{A,C,G,T}
would get marshaled to [0,1,2,3]
.
type Base int
const (
A Base = iota
C
G
T
)
Here's an example comparing both approaches:
Simple way:
BufferedImage readImage = null;
try {
readImage = ImageIO.read(new File(your path);
int h = readImage.getHeight();
int w = readImage.getWidth();
} catch (Exception e) {
readImage = null;
}
The simplest solution to run your script under virtualenv's interpreter is to replace the default shebang line with path to your virtualenv's interpreter like so at the beginning of the script:
#!/path/to/project/venv/bin/python
Make the script executable:
chmod u+x script.py
Run the script:
./script.py
Voila!
Based on my comment to the accepted answer, there are a lot potential pitfalls that you may encounter by declaring font-sizes smaller than 12px
. By declaring styles that lead to computed font-sizes of less than 12px
, like so:
html {
font-size: 8px;
}
p {
font-size: 1.4rem;
}
// Computed p size: 11px.
You'll run into issues with browsers, like Chrome with a Chinese language pack that automatically renders any font sizes computed under 12px
as 12px
. So, the following is true:
h6 {
font-size: 12px;
}
p {
font-size: 8px;
}
// Both render at 12px in Chrome with a Chinese language pack.
// How unpleasant of a surprise.
I would also argue that for accessibility reasons, you generally shouldn't use sizes under 12px. You might be able to make a case for captions and the like, but again--prepare to be surprised under some browser setups, and prepared to make your grandma squint when she's trying to read your content.
I would instead, opt for something like this:
h1 {
font-size: 2.5rem;
}
h2 {
font-size: 2.25rem;
}
h3 {
font-size: 2rem;
}
h4 {
font-size: 1.75rem;
}
h5 {
font-size: 1.5rem;
}
h6 {
font-size: 1.25rem;
}
p {
font-size: 1rem;
}
@media (max-width: 480px) {
html {
font-size: 12px;
}
}
@media (min-width: 480px) {
html {
font-size: 13px;
}
}
@media (min-width: 768px) {
html {
font-size: 14px;
}
}
@media (min-width: 992px) {
html {
font-size: 15px;
}
}
@media (min-width: 1200px) {
html {
font-size: 16px;
}
}
You'll find that tons of sites that have to focus on accessibility use rather large font sizes, even for p
elements.
As a side note, setting margin-bottom
equal to the font-size
usually also tends to be attractive, i.e.:
h1 {
font-size: 2.5rem;
margin-bottom: 2.5rem;
}
Good luck.
I believe this should work fine for any DataFrame columns list.
def column_list(x):
column_list_df = []
for col_name in x.columns:
y = col_name, len(x[col_name].unique())
column_list_df.append(y)
return pd.DataFrame(column_list_df)
column_list_df.rename(columns={0: "Feature", 1: "Value_count"})
The function "column_list" checks the columns names and then checks the uniqueness of each column values.
According to Bootstrap documentation of 2.3.2 and 3, the class should be defined like this:
Bootstrap 2.3.2
<ul class="inline">
<li>...</li>
</ul>
Bootstrap 3
<ul class="list-inline">
<li>...</li>
</ul>
Since i am little late here but i wanted to share how actually list comprehension works especially nested list comprehension :
New_list= [[float(y) for x in l]
is actually same as :
New_list=[]
for x in l:
New_list.append(x)
And now nested list comprehension :
[[float(y) for y in x] for x in l]
is same as ;
new_list=[]
for x in l:
sub_list=[]
for y in x:
sub_list.append(float(y))
new_list.append(sub_list)
print(new_list)
output:
[[40.0, 20.0, 10.0, 30.0], [20.0, 20.0, 20.0, 20.0, 20.0, 30.0, 20.0], [30.0, 20.0, 30.0, 50.0, 10.0, 30.0, 20.0, 20.0, 20.0], [100.0, 100.0], [100.0, 100.0, 100.0, 100.0, 100.0], [100.0, 100.0, 100.0, 100.0]]

sudo nano /usr/share/phpmyadmin/libraries/sql.lib.php
Find for count($analyzed_sql_results['select_expr']
code on file. You can get this at line ~613.
|| (count($analyzed_sql_results['select_expr'] == 1)
Just replace with code :

Save the file and reload PhpMyAdmin.

Find log enabled or not?
SHOW VARIABLES LIKE '%log%';
Set the logs:-
SET GLOBAL general_log = 'ON';
SET GLOBAL slow_query_log = 'ON';
First represent the epoch of the millisecond time as a date (usually 1/1/1970), then add your millisecond time divided by the number of milliseconds in a day (86400000):
=DATE(1970,1,1)+(A1/86400000)
If your cell is properly formatted, you should see a human-readable date/time.
You could try to assign properties to the ENUM you're trying to create and statically contruct it by using a loaded properties file. Big hack, but it works :)
I know it's an old thread, but I think the current solution (using hardcoded string identifier for given view controller) is very prone to errors.
I've created a build time script (which you can access here), which will create a compiler safe way for accessing and instantiating view controllers from all storyboard within the given project.
For example, view controller named vc1 in Main.storyboard will be instantiated like so:
let vc: UIViewController = R.storyboard.Main.vc1^ // where the '^' character initialize the controller

16 is severity and 1 is state, more specifically following example might give you more detail on syntax and usage:
BEGIN TRY
-- RAISERROR with severity 11-19 will cause execution to
-- jump to the CATCH block.
RAISERROR ('Error raised in TRY block.', -- Message text.
16, -- Severity.
1 -- State.
);
END TRY
BEGIN CATCH
DECLARE @ErrorMessage NVARCHAR(4000);
DECLARE @ErrorSeverity INT;
DECLARE @ErrorState INT;
SELECT
@ErrorMessage = ERROR_MESSAGE(),
@ErrorSeverity = ERROR_SEVERITY(),
@ErrorState = ERROR_STATE();
-- Use RAISERROR inside the CATCH block to return error
-- information about the original error that caused
-- execution to jump to the CATCH block.
RAISERROR (@ErrorMessage, -- Message text.
@ErrorSeverity, -- Severity.
@ErrorState -- State.
);
END CATCH;

You need to use Integer.parseInt(String)
private void jTextField2MouseClicked(java.awt.event.MouseEvent evt) {
if(evt.getSource()==jTextField2){
int jml = Integer.parseInt(jTextField3.getText());
jTextField1.setText(numberToWord(jml));
}
}
you must have read about function call . here i give you example of it.
<?php
funtion pr($n)
{
echo $n;
}
?>
<form action="<?php $f=$_POST['input'];pr($f);?>" method="POST">
<input name=input type=text></input>
</form>
This answer serves as a simplification and optimisation over Leopoldo's answer.
Trigger a function from your input on every keydown like this:
<input type="text" ng-keydown="onlyNumbers($event);"/>
You can describe the function in this manner in your controller
$scope.onlyNumbers = function(event){
// 'up': 38,'right':39,'down':40,'left':37,
// 'escape':27,'backspace':8,'tab':9,'enter':13,'del':46,
// '0':48,'1':49,'2':50,'3':51,'4':52,'5':53,'6':54,'7':55,'8':56,'9':57
var keys = { 38:true,39:true,40:true,37:true,27:true,8:true,9:true,13:true,
46:true,48:true,49:true, 50:true,51:true,52:true,53:true,
54:true,55:true,56:true,57:true };
// if the pressed key is not listed, do not perform any action
if(!keys[event.keyCode]) { event.preventDefault(); }
}
In case you're using Angular 2+, you can call this same function in this manner:
<input type="text" (keydown)="onlyNumbers($event);"/>
Your Angular 2+ function should look something like this:
onlyNumbers(event) { // the logic here }
ServicePointManager.ServerCertificateValidationCallback +=
(mender, certificate, chain, sslPolicyErrors) => true;

This only works if Table_A and Table_B have the same schemas
The options discussed above won't work because they are not part of the CSS
specification (it is jQuery
extension). Having spent 2-3 days digging around for information, I found that the only way to select the Text of the selected option from the drop down is:
{ $("select", id:"Some_ID").find("option[selected='selected']")}
Refer to additional notes below:
Because :selected is a jQuery
extension and not part of the CSS
specification, queries using :selected cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :selected to select elements, first select the elements using a pure CSS
selector, then use .filter(":selected")
. (copied from: http://api.jquery.com/selected-selector/)

With a BorderLayout you need to use setPreferredSize
instead of setSize
copy the column paste it into notepad copy it again paste special as Text
Could be much simpler if you use TryParse

As noted by @chrfin in comments, you can make it an extension method very easily just by adding this
before the parameter type which can be handy.
In .NET Framework 4 and MVC this is the only representation that worked:

Instead of sudo, try
su - username command
In my experience, sudo is not always available on RHEL systems, but su is, because su is part of the coreutils package whereas sudo is in the sudo package.
Truncate Pipe with optional params:

This is an attempt to improve on Brent Bradburn's great approach as follows:
sh -c
)-f <file>
@
to prevent it from being echoed before executionCuriously, GNU make
has no feature for listing just the names of targets defined in a makefile. While the -p
option produces output that includes all targets, it buries them in a lot of other information and also executes the default target (which could be suppressed with -f/dev/null
).
Place the following rule in a makefile for GNU make
to implement a target named list
that simply lists all target names in alphabetical order - i.e.: invoke as make list
:
.PHONY: list
list:
@$(MAKE) -pRrq -f $(lastword $(MAKEFILE_LIST)) : 2>/dev/null | awk -v RS= -F: '/^# File/,/^# Finished Make data base/ {if ($$1 !~ "^[#.]") {print $$1}}' | sort | egrep -v -e '^[^[:alnum:]]' -e '^$@$$'
Important: On pasting this, make sure that the last line is indented by exactly 1 actual tab char. (spaces do not work).
Note that sorting the resulting list of targets is the best option, since not sorting doesn't produce a helpful ordering in that the order in which the targets appear in the makefile is not preserved.
Also, the sub-targets of a rule comprising multiple targets are invariably output separately and will therefore, due to sorting, usually not appear next to one another; e.g., a rule starting with a z:
will not have targets a
and z
listed next to each other in the output, if there are additional targets.
Explanation of the rule:
.PHONY: list
$(MAKE) -pRrq -f $(lastword $(MAKEFILE_LIST)) : 2>/dev/null
make
again in order to print and parse the database derived from the makefile:
-p
prints the database-Rr
suppresses inclusion of built-in rules and variables-q
only tests the up-to-date-status of a target (without remaking anything), but that by itself doesn't prevent execution of recipe commands in all cases; hence:-f $(lastword $(MAKEFILE_LIST))
ensures that the same makefile is targeted as in the original invocation, regardless of whether it was targeted implicitly or explicitly with -f ...
.include
directives; to address this, define variable THIS_FILE := $(lastword $(MAKEFILE_LIST))
before any include
directives and use -f $(THIS_FILE)
instead.:
is a deliberately invalid target that is meant to ensure that no commands are executed; 2>/dev/null
suppresses the resulting error message. Note: This relies on -p
printing the database nonetheless, which is the case as of GNU make 3.82. Sadly, GNU make offers no direct option to just print the database, without also executing the default (or given) task; if you don't need to target a specific Makefile, you may use make -p -f/dev/null
, as recommended in the man
page.-v RS=
/^# File/,/^# Finished Make data base/
if ($$1 !~ "^[#.]")
#
... ignores non-targets, whose blocks start with # Not a target:
.
... ignores special targets:
egrep -v -e '^[^[:alnum:]]' -e '^$@$$'
removes unwanted targets from the output:
'^[^[:alnum:]]'
... excludes hidden targets, which - by convention - are targets that start neither with a letter nor a digit.'^$@$$'
... excludes the list
target itselfRunning make list
then prints all targets, each on its own line; you can pipe to xargs
to create a space-separated list instead.

Did you accidentally create the repository using the
root
user?
It just happens that I created the git repository as the root
user.
I deleted the git repository and created it again without sudo
and it works.
Well best option is %java_home%\bin\xjc -p [your namespace] [xsd_file].xsd
.
I also have a question if we have an option to do reverse engineering here. if yes can we generate xsd from pojo class?
A concise overview of the challenges of SSH inside Docker containers is detailed here. For connecting to trusted remotes from within a container without leaking secrets there are a few ways:
~/.ssh
to container. (Development only, potentially insecure)Beyond these there's also the possibility of using a key-store running in a separate docker container accessible at runtime when using Compose. The drawback here is additional complexity due to the machinery required to create and manage a keystore such as Vault by HashiCorp.
For SSH key use in a stand-alone Docker container see the methods linked above and consider the drawbacks of each depending on your specific needs. If, however, you're running inside Compose and want to share a key to an app at runtime (reflecting practicalities of the OP) try this:
docker-compose.env
file and add it to your .gitignore
file.docker-compose.yml
and add env_file
for service requiring the key.process.node.DEPLOYER_RSA_PUBKEY
in the case of a Node.js application.The above approach is ideal for development and testing and, while it could satisfy production requirements, in production you're better off using one of the other methods identified above.

Based on official android docs, you can use this method in a Helper or Util class to get current battery percentage:
Java version:
public static int getBatteryPercentage(Context context) {
if (Build.VERSION.SDK_INT >= 21) {
BatteryManager bm = (BatteryManager) context.getSystemService(BATTERY_SERVICE);
return bm.getIntProperty(BatteryManager.BATTERY_PROPERTY_CAPACITY);
} else {
IntentFilter iFilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
Intent batteryStatus = context.registerReceiver(null, iFilter);
int level = batteryStatus != null ? batteryStatus.getIntExtra(BatteryManager.EXTRA_LEVEL, -1) : -1;
int scale = batteryStatus != null ? batteryStatus.getIntExtra(BatteryManager.EXTRA_SCALE, -1) : -1;
double batteryPct = level / (double) scale;
return (int) (batteryPct * 100);
}
}
Kotlin version:
fun getBatteryPercentage(context: Context): Int {
return if (Build.VERSION.SDK_INT >= 21) {
val bm = context.getSystemService(BATTERY_SERVICE) as BatteryManager
bm.getIntProperty(BatteryManager.BATTERY_PROPERTY_CAPACITY)
} else {
val iFilter = IntentFilter(Intent.ACTION_BATTERY_CHANGED)
val batteryStatus: Intent = context.registerReceiver(null, iFilter)
val level = batteryStatus?.getIntExtra(BatteryManager.EXTRA_LEVEL, -1)
val scale = batteryStatus?.getIntExtra(BatteryManager.EXTRA_SCALE, -1)
val batteryPct = level / scale.toDouble()
(batteryPct * 100).toInt()
}
}
Lots of answers here, but here comes a working example with code that you can copy and paste and test immediately:
For me the error 12514 was solved after specifying the correct SERVICE_NAME.
You find that on the server in the file tnsnames.ora
which comes with 3 predefined service names (one of them is "XE").
HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\ODP.NET\4.112.4.0\DllPath
. On 64 bit machines write additionally to HKLM\SOFTWARE\Wow6432Node\Oracle\...
HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\ODP.NET\4.121.2.0\DllPath
Oracle.ManagedDataAccess.dll
which is only 4 MB and is a pure managed DLL which works in 32 bit and 64 bit processes as well and depends on no other DLL and does not require any registry entries.using Oracle.DataAccess.Client; or using Oracle.ManagedDataAccess.Client; .... string oradb = "Data Source=(DESCRIPTION=" + "(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.1.158)(PORT=1521)))" + "(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=XE)));" + "User Id=SYSTEM;Password=xxx;"; using (OracleConnection conn = new OracleConnection(oradb)) { conn.Open(); using (OracleCommand cmd = new OracleCommand()) { cmd.Connection = conn; cmd.CommandText = "select TABLESPACE_NAME from DBA_DATA_FILES"; using (OracleDataReader dr = cmd.ExecuteReader()) { while (dr.Read()) { listBox.Items.Add(dr["TABLESPACE_NAME"]); } } } }
If the SERVICE_NAME=XE
is wrong you get error 12514. The SERVICE_NAME
is optional. You can also leave it away.
In latest Angular 7/8, you can use the simplest approach:-
import { HttpClient, HttpHeaders, HttpParams } from '@angular/common/http';
getDetails(searchParams) {
const httpOptions = {
headers: { 'Content-Type': 'application/json' },
params: { ...searchParams}
};
return this.http.get(this.Url, httpOptions);
}
I think you can't do it because Id is unique you have to use it for one element . You can use class for the purpose
For a terse, pure flexbox option, group the left-aligned items and the right-aligned items:
<div class="wrap">
<div>
<span>One</span>
<span>Two</span>
</div>
<div>Three</div>
</div>
and use space-between
:
.wrap {
display: flex;
background: #ccc;
justify-content: space-between;
}
This way you can group multiple items to the right(or just one).
You can use Flexible, in this case the person.name could be a long name (Labels and BlankSpace are custom classes that return widgets) :
new Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
new Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
new Flexible(
child: Labels.getTitle_2(person.name,
color: StyleColors.COLOR_BLACK)),
BlankSpace.column(3),
Labels.getTitle_1(person.likes())
]),
BlankSpace.row(3),
Labels.getTitle_2(person.shortDescription),
],
)

You have an error in you script tag construction, this:
<script language="JavaScript" type="text/javascript" script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.0/jquery-ui.min.js"></script>
Should look like this:
<script language="JavaScript" type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.0/jquery-ui.min.js"></script>
You have a 'script' word lost in the middle of your script tag. Also you should remove the http:// to let the browser decide whether to use HTTP or HTTPS.
UPDATE
But your main error is that you are including jQuery UI (ONLY) you must include jQuery first! jQuery UI and jQuery are used together, not in separate. jQuery UI depends on jQuery. You should put this line before jQuery UI:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>

Here is a post which introduces different types of keystore in Java and the differences among different types of keystore. http://www.pixelstech.net/article/1408345768-Different-types-of-keystore-in-Java----Overview
Below are the descriptions of different keystores from the post:
JKS, Java Key Store. You can find this file at sun.security.provider.JavaKeyStore. This keystore is Java specific, it usually has an extension of jks. This type of keystore can contain private keys and certificates, but it cannot be used to store secret keys. Since it's a Java specific keystore, so it cannot be used in other programming languages.
JCEKS, JCE key store. You can find this file at com.sun.crypto.provider.JceKeyStore. This keystore has an extension of jceks. The entries which can be put in the JCEKS keystore are private keys, secret keys and certificates.
PKCS12, this is a standard keystore type which can be used in Java and other languages. You can find this keystore implementation at sun.security.pkcs12.PKCS12KeyStore. It usually has an extension of p12 or pfx. You can store private keys, secret keys and certificates on this type.
PKCS11, this is a hardware keystore type. It servers an interface for the Java library to connect with hardware keystore devices such as Luna, nCipher. You can find this implementation at sun.security.pkcs11.P11KeyStore. When you load the keystore, you no need to create a specific provider with specific configuration. This keystore can store private keys, secret keys and cetrificates. When loading the keystore, the entries will be retrieved from the keystore and then converted into software entries.
Here is what I use when adding validation to form:
// Adding validation to form.
$(form).validate({
rules: {
title: {
required: true,
minlength: 3,
},
server: {
ipAddress: true,
required: true
}
},
highlight: function(element) {
$(element).closest('.form-group').removeClass('has-success').addClass('has-error');
},
success: function(element) {
$(element).closest('.form-group').removeClass('has-error').addClass('has-success');
},

This worked for me for Bootstrap 3 styling when using the jquery validation library.
var result = (35.8 / 100) * 10000;
(Thank you jball for this change of order of operations. I didn't consider it).
I think that every JSON response should contain a property (e.g. {authenticated: false}) and the client has to test it everytime: if false, then the Angular controller/service will "redirect" to the login page.
And what happen if the user catch de JSON and change the bool to True?
I think you should never rely on client side to do these kind of stuff. If the user is not authenticated, the server should just redirect to a login/error page.
#temp is materalized and CTE is not.
CTE is just syntax so in theory it is just a subquery. It is executed. #temp is materialized. So an expensive CTE in a join that is execute many times may be better in a #temp. On the other side if it is an easy evaluation that is not executed but a few times then not worth the overhead of #temp.
The are some people on SO that don't like table variable but I like them as the are materialized and faster to create than #temp. There are times when the query optimizer does better with a #temp compared to a table variable.
The ability to create a PK on a #temp or table variable gives the query optimizer more information than a CTE (as you cannot declare a PK on a CTE).
For creating a new file
x1 = np.random.randn(100, 2)
df1 = pd.DataFrame(x1)
with pd.ExcelWriter('sample.xlsx') as writer:
df1.to_excel(writer, sheet_name='x1')
For appending to the file, use the argument mode='a'
in pd.ExcelWriter
.
x2 = np.random.randn(100, 2)
df2 = pd.DataFrame(x2)
with pd.ExcelWriter('sample.xlsx', engine='openpyxl', mode='a') as writer:
df2.to_excel(writer, sheet_name='x2')
Default is mode ='w'
.
See documentation.
The first solution is to use the java.util.Random
class:
import java.util.Random;
Random rand = new Random();
// Obtain a number between [0 - 49].
int n = rand.nextInt(50);
// Add 1 to the result to get a number from the required range
// (i.e., [1 - 50]).
n += 1;
Another solution is using Math.random()
:
double random = Math.random() * 49 + 1;
or
int random = (int)(Math.random() * 50 + 1);
sed
is the Stream EDitor. It can do a whole pile of really cool things, but the most common is text replacement.
The s,%,$,g
part of the command line is the sed
command to execute. The s
stands for substitute, the ,
characters are delimiters (other characters can be used; /
, :
and @
are popular). The %
is the pattern to match (here a literal percent sign) and the $
is the second pattern to match (here a literal dollar sign). The g
at the end means to g
lobally replace on each line (otherwise it would only update the first match).
Please see my project of the cross-browser filter of value of the text input element on your web page using JavaScript language: Input Key Filter . You can filter the value as an integer number, a float number, or write a custom filter, such as a phone number filter. See an example of custom filter of input of an float number with decimal pointer and limitation to 2 digit after decimal pointer:

If you want something lighter than a Label or other ASP.NET-specific server control you can just use a standard HTML DIV or SPAN and with runat="server", e.g.:
Markup:
<span runat="server" id="FooSpan"></span>
Code:
FooSpan.Text = "Foo";
You can use below code for your solution:-
public void Linq94()
{
int[] numbersA = { 0, 2, 4, 5, 6, 8, 9 };
int[] numbersB = { 1, 3, 5, 7, 8 };
var allNumbers = numbersA.Concat(numbersB);
Console.WriteLine("All numbers from both arrays:");
foreach (var n in allNumbers)
{
Console.WriteLine(n);
}
}
A better polyfill from the MDN that supports removal of BOM and NBSP:
if (!String.prototype.trim) {
String.prototype.trim = function () {
return this.replace(/^[\s\uFEFF\xA0]+|[\s\uFEFF\xA0]+$/g, '');
};
}
Bear in mind that modifying built-in prototypes comes with a performance hit (due to the JS engine bailing on a number of runtime optimizations), and in performance critical situations you may need to consider the alternative of defining myTrimFunction(string)
instead. That being said, if you are targeting an older environment without native .trim()
support, you are likely to have more important performance issues to deal with.

You need to store it in a String
variable first before displaying it like so:
String Txt = TxtBoxContent.getText();
System.out.println(Txt);
This approach seems more straightforward, avoiding the need to individually select each file:
# keep remote files
git merge --strategy-option theirs
# keep local files
git merge --strategy-option ours
or
# keep remote files
git pull -Xtheirs
# keep local files
git pull -Xours
Copied directly from: Resolve Git merge conflicts in favor of their changes during a pull
But while mocking read-only properties means properties with getter method only you should declare it as virtual otherwise System.NotSupportedException will be thrown because it is only supported in VB as moq internally override and create proxy when we mock anything.
I've published instructions for how to run the Firefox SQLite Manager outside of Firefox, since FF hase become so bloated in the last few releases. It's really easy and I've even compiled a DMG for the sqlite gui if anyone wants it.
Your form doesn't contain any input tag other than the file so in your controller action you cannot expect to get anything else than the uploaded file (that's all that's being sent to the server). One way to achieve this would be to include a hidden tag containing the id of the model which will allow you to retrieve it from your datastore inside the controller action you are posting to (use this if the user is not supposed to modify the model but simply attach a file):
@using (Html.BeginForm("Uploadfile", "Containers", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.HiddenFor(x => x.Id)
<input type="file" name="file" id="file" />
<input type="submit" value="submit" />
}
and then in your controller action:
[HttpPost]
public ActionResult Uploadfile(int id, HttpPostedFileBase file)
{
Containers containers = Repository.GetContainers(id);
...
}
On the other hand if you wanted to allow the user to modify this model then you will need to include the proper input fields for each field of your model that you want to be sent to the server:
@using (Html.BeginForm("Uploadfile", "Containers", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.TextBoxFor(x => x.Prop1)
@Html.TextBoxFor(x => x.Prop2)
@Html.TextBoxFor(x => x.Prop3)
<input type="file" name="file" id="file" />
<input type="submit" value="submit" />
}
and then you will have the default model binder reconstruct this model from the request:
[HttpPost]
public ActionResult Uploadfile(Container containers, HttpPostedFileBase file)
{
...
}
First you need update npm, lite-server and typescript:
sudo npm update -g && sudo npm install -g concurrently lite-server typescript
Delete node_modules folder from your Angular project directory (if exist). Next run:
npm install
After that resolve ENOSPC errors:
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
Finally:
npm start

On 32-bit machine sizeof pointer is 32 bits ( 4 bytes), while on 64 bit machine it's 8 byte. Regardless of what data type they are pointing to, they have fixed size.
You can essentially do this 2 ways:
Add a file called .htaccess
in your root folder, and add something like this:
RewriteEngine on
RewriteRule ^/?Some-text-goes-here/([0-9]+)$ /picture.php?id=$1
This will tell Apache to enable mod_rewrite for this folder, and if it gets asked a URL matching the regular expression it rewrites it internally to what you want, without the end user seeing it. Easy, but inflexible, so if you need more power:
Put the following in your .htaccess instead: (note the leading slash)
FallbackResource /index.php
This will tell it to run your index.php
for all files it cannot normally find in your site. In there you can then for example:
$path = ltrim($_SERVER['REQUEST_URI'], '/'); // Trim leading slash(es)
$elements = explode('/', $path); // Split path on slashes
if(empty($elements[0])) { // No path elements means home
ShowHomepage();
} else switch(array_shift($elements)) // Pop off first item and switch
{
case 'Some-text-goes-here':
ShowPicture($elements); // passes rest of parameters to internal function
break;
case 'more':
...
default:
header('HTTP/1.1 404 Not Found');
Show404Error();
}
This is how big sites and CMS-systems do it, because it allows far more flexibility in parsing URLs, config and database dependent URLs etc. For sporadic usage the hardcoded rewrite rules in .htaccess
will do fine though.
I have used winston logger earlier.
Nowadays I am using below simpler code from experience:
Set the environment variable from cmd/ command line (on Windows):
cmd
setx LOG_LEVEL info
Or, you could have a variable in your code if you like, but above is better.
Restart cmd/ command line, or, IDE/ editor like Netbeans
Have below like code:
console.debug = console.log; // define debug function
console.silly = console.log; // define silly function
switch (process.env.LOG_LEVEL) {
case 'debug':
case 'silly':
// print everything
break;
case 'dir':
case 'log':
console.debug = function () {};
console.silly = function () {};
break;
case 'info':
console.debug = function () {};
console.silly = function () {};
console.dir = function () {};
console.log = function () {};
break;
case 'trace': // similar to error, both may print stack trace/ frames
case 'warn': // since warn() function is an alias for error()
case 'error':
console.debug = function () {};
console.silly = function () {};
console.dir = function () {};
console.log = function () {};
console.info = function () {};
break;
}
Now use all console.* as below:
console.error(' this is a error message '); // will print
console.warn(' this is a warn message '); // will print
console.trace(' this is a trace message '); // will print
console.info(' this is a info message '); // will print, LOG_LEVEL is set to this
console.log(' this is a log message '); // will NOT print
console.dir(' this is a dir message '); // will NOT print
console.silly(' this is a silly message '); // will NOT print
console.debug(' this is a debug message '); // will NOT print
Now, based on your LOG_LEVEL settings made in the point 1 (like, setx LOG_LEVEL log
and restart command line), some of the above will print, others won't print
Hope that helped.
Try this (OS X only):
brew install homebrew/versions/gradle110
gradle build
You can use gradle tasks
to see all tasks available for the current project. No Android Studio
is needed here.
Assuming alphanumeric words, you can use:
Search = ^([A-Za-z0-9]+)$
Replace = able:"\1"
Or, if you just want to highlight the lines and use "Replace All" & "In Selection" (with the same replace):
Search = ^(.+)$
^
points to the start of the line.
$
points to the end of the line.
\1
will be the source match within the parentheses.
Specify the paths explicitly:
git diff HEAD:full/path/to/foo full/path/to/bar
Check out the --find-renames
option in the git-diff
docs.

Here is a very simple but unsafe approach to find the square-root of a number. Unsafe because it only works by natural numbers, where you know that the base respectively the exponent are natural numbers. I had to use it for a task where i was neither allowed to use the #include<cmath> -library, nor i was allowed to use pointers.
potency = base ^ exponent
// FUNCTION: square-root
int sqrt(int x)
{
int quotient = 0;
int i = 0;
bool resultfound = false;
while (resultfound == false) {
if (i*i == x) {
quotient = i;
resultfound = true;
}
i++;
}
return quotient;
}
It's little change in boostrap 4. To align navbar to right side, you've to make only two changes. they are:
navbar-nav
class add w-100
as navbar-nav w-100
to make width as 100nav-item dropdown
class add ml-auto
as nav-item dropdown ml-auto
to make margin left as auto.If you didn't understand, please refer the image that i've attached to this.

Most of the answers use Handler but I give a different solution to delay in activity, fragment, view model with Android Lifecycle ext. This way will auto cancel when the lifecycle begins destroyed.
In Activity or Fragment:
lifecycleScope.launch {
delay(DELAY_MS)
doSomething()
}
In ViewModel:
viewModelScope.lanch {
delay(DELAY_MS)
doSomething()
}
In suspend function: (Kotlin Coroutine)
suspend fun doSomethingAfter(){
delay(DELAY_MS)
doSomething()
}
If you get an error with the lifecycleScope not found - import to gradle file:
implementation "androidx.lifecycle:lifecycle-runtime-ktx:2.2.0"
Use Underscore.js isEqual method http://underscorejs.org/#isEqual
In my case I just ignored the following in application.properties file:
# Hibernate
#spring.jpa.hibernate.ddl-auto=update
It works for me....
For ios6 using autolayout I had to add a little bit of code to remove the constraints too.
NSMutableArray * constraints_to_remove = [ @[] mutableCopy] ;
for( NSLayoutConstraint * constraint in tagview.constraints) {
if( [tagview.subviews containsObject:constraint.firstItem] ||
[tagview.subviews containsObject:constraint.secondItem] ) {
[constraints_to_remove addObject:constraint];
}
}
[tagview removeConstraints:constraints_to_remove];
[ [tagview subviews] makeObjectsPerformSelector:@selector(removeFromSuperview)];
I'm sure theres a neater way to do this, but it worked for me. In my case I could not use a direct [tagview removeConstraints:tagview.constraints]
as there were constraints set in XCode that were getting cleared.
log4j2 has a very flexible configuration system (which IMHO is more a distraction than a help), you can even use JSON. See https://logging.apache.org/log4j/2.x/manual/configuration.html for a reference.
Personally, I just recently started using log4j2, but I'm tending toward the "strict XML" configuration (that is, using attributes instead of element names), which can be schema-validated.
Here is my simple example using autoconfiguration and strict mode, using a "Property" for setting the filename:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration monitorinterval="30" status="info" strict="true">
<Properties>
<Property name="filename">log/CelsiusConverter.log</Property>
</Properties>
<Appenders>
<Appender type="Console" name="Console">
<Layout type="PatternLayout" pattern="%d %p [%t] %m%n" />
</Appender>
<Appender type="Console" name="FLOW">
<Layout type="PatternLayout" pattern="%C{1}.%M %m %ex%n" />
</Appender>
<Appender type="File" name="File" fileName="${filename}">
<Layout type="PatternLayout" pattern="%d %p %C{1.} [%t] %m%n" />
</Appender>
</Appenders>
<Loggers>
<Root level="debug">
<AppenderRef ref="File" />
<AppenderRef ref="Console" />
<!-- Use FLOW to trace down exact method sending the msg -->
<!-- <AppenderRef ref="FLOW" /> -->
</Root>
</Loggers>
</Configuration>
0 will get printed.
As in C++ true refers to 1 and false refers to 0.
In case, you want to print false instead of 0,then you have to sets the boolalpha format flag for the str stream.
When the boolalpha format flag is set, bool values are inserted/extracted by their textual representation: either true or false, instead of integral values.
#include <iostream>
int main()
{
std::cout << std::boolalpha << false << std::endl;
}
output:
false
If you append json data to query string, and parse it later in web api side. you can parse complex object. It's useful rather than post json object style. This is my solution.
//javascript file
var data = { UserID: "10", UserName: "Long", AppInstanceID: "100", ProcessGUID: "BF1CC2EB-D9BD-45FD-BF87-939DD8FF9071" };
var request = JSON.stringify(data);
request = encodeURIComponent(request);
doAjaxGet("/ProductWebApi/api/Workflow/StartProcess?data=", request, function (result) {
window.console.log(result);
});
//webapi file:
[HttpGet]
public ResponseResult StartProcess()
{
dynamic queryJson = ParseHttpGetJson(Request.RequestUri.Query);
int appInstanceID = int.Parse(queryJson.AppInstanceID.Value);
Guid processGUID = Guid.Parse(queryJson.ProcessGUID.Value);
int userID = int.Parse(queryJson.UserID.Value);
string userName = queryJson.UserName.Value;
}
//utility function:
public static dynamic ParseHttpGetJson(string query)
{
if (!string.IsNullOrEmpty(query))
{
try
{
var json = query.Substring(7, query.Length - 7); //seperate ?data= characters
json = System.Web.HttpUtility.UrlDecode(json);
dynamic queryJson = JsonConvert.DeserializeObject<dynamic>(json);
return queryJson;
}
catch (System.Exception e)
{
throw new ApplicationException("can't deserialize object as wrong string content!", e);
}
}
else
{
return null;
}
}
Unlike some browsers, Java follows the HTTPS specification strictly when it comes to the server identity verification (RFC 2818, Section 3.1) and IP addresses.
When using a host name, it's possible to fall back to the Common Name in the Subject DN of the server certificate, instead of using the Subject Alternative Name.
When using an IP address, there must be a Subject Alternative Name entry (of type IP address, not DNS name) in the certificate.
You'll find more details about the specification and how to generate such a certificate in this answer.
you can also use "global"
Example:
declare like this :
app.use(function(req,res,next){
global.site_url = req.headers.host; // hostname = 'localhost:8080'
next();
});
Use like this: in any views or ejs file <% console.log(site_url); %>
in js files console.log(site_url);
