I had the same issue with setting StatusCode
and then Response.End
in HandleUnauthorizedRequest
method of AuthorizeAttribute
var ctx = filterContext.HttpContext;
ctx.Response.StatusCode = (int)HttpStatusCode.Forbidden;
ctx.Response.End();
If you are using .NET 4.5+, add this line before Response.StatusCode
filterContext.HttpContext.Response.SuppressFormsAuthenticationRedirect = true;
If you are using .NET 4.0, try SuppressFormsAuthenticationRedirectModule.
Step 1 . Go to Androidsdk\platform-tools on PC/Laptop
Step 2 :
Connect your device via USB and run:
adb kill-server
then run
adb tcpip 5555
you will see below message...
daemon not running. starting it now on port 5037 * daemon started successfully * restarting in TCP mode port: 5555
Step3:
Now open new CMD window,
Go to Androidsdk\platform-tools
Now run
adb connect xx.xx.xx.xx:5555
(xx.xx.xx.xx is device IP)
Step4: Disconnect your device from USB and it will work as if connected from your Android studio.
I have a solution that works well for me. It consists of a local jenkins running in docker and a git web hook to trigger the pipeline in the local jenkins on every commit. You no longer need to push to your github or bitbucket repository to test the pipeline.
This has only been tested in a linux environment.
It is fairly simple to make this work although this instruction is a tad long. Most steps are there.
Create a file called Dockerfile in place of your choosing. I'm placing it in /opt/docker/jenkins/Dockerfile
fill it with this:
FROM jenkins/jenkins:lts
USER root
RUN apt-get -y update && apt-get -y upgrade
# Your needed installations goes here
USER jenkins
Build the local_jenkins image
This you will need to do only once or after you have added something to the Dockerfile.
$ docker build -t local_jenkins /opt/docker/jenkins/
Start and restart local_jenkins
From time to time you want to start and restart jenkins easily. E.g. after a reboot of your machine. For this I made an alias that I put in .bash_aliases
in my home folder.
$ echo "alias localjenkinsrestart='docker stop jenkins;docker rm jenkins;docker run --name jenkins -i -d -p 8787:8080 -p 50000:50000 -v /opt/docker/jenkins/jenkins_home:/var/jenkins_home:rw local_jenkins'" >> ~/.bash_aliases
$ source .bash_aliases # To make it work
Make sure the /opt/docker/jenkins/jenkins_home
folder exists and that you have user read and write rights to it.
To start or restart your jenkins just type:
$ localjenkinsrestart
Everything you do in your local jenkins will be stored in the folder /opt/docker/jenkins/jenkins_home and preserved between restarts.
Create a ssh access key in your docker jenkins
This is a very important part for this to work. First we start the docker container and create a bash shell to it:
$ localjenkinsrestart
$ docker exec -it jenkins /bin/bash
You have now entered into the docker container, this you can see by something like jenkins@e7b23bad10aa:/$
in your terminal. The hash after the @ will for sure differ.
Create the key
jenkins@e7b23bad10aa:/$ ssh-keygen
Press enter on all questions until you get the prompt back
Copy the key to your computer. From within the docker container your computer is 172.17.0.1 should you wonder.
jenkins@e7b23bad10aa:/$ ssh-copy-id [email protected]
user = your username and 172.17.0.1 is the ip address to your computer from within the docker container.
You will have to type your password at this point.
Now lets try to complete the loop by ssh-ing to your computer from within the docker container.
jenkins@e7b23bad10aa:/$ ssh [email protected]
This time you should not need to enter you password. If you do, something went wrong and you have to try again.
You will now be in your computers home folder. Try ls
and have a look.
Do not stop here since we have a chain of ssh shells that we need to get out of.
$ exit
jenkins@e7b23bad10aa:/$ exit
Right! Now we are back and ready to continue.
Install your Jenkins
You will find your local Jenkins in your browser at http://localhost:8787.
First time you point your browser to your local Jenkins your will be greated with a Installation Wizard. Defaults are fine, do make sure you install the pipeline plugin during the setup though.
Setup your jenkins
It is very important that you activate matrix based security on http://localhost:8787/configureSecurity and give yourself all rights by adding yourself to the matrix and tick all the boxes. (There is a tick-all-boxes icon on the far right)
Jenkins’ own user database
as the Security RealmMatrix-based security
in the Authorization sectionUser/group to add:
and click on the [ Add ]
buttonPrevent Cross Site Request Forgery exploits
is unchecked. (Since this Jenkins is only reachable from your computer this isn't such a big deal)[ Save ]
and log out of Jenkins and in again just to make sure it works.
If it doesn't you have to start over from the beginning and emptying the /opt/docker/jenkins/jenkins_home
folder before restartingAdd the git user
We need to allow our git hook to login to our local Jenkins with minimal rights. Just to see and build jobs is sufficient. Therefore we create a user called git
with password login
.
Direct your browser to http://localhost:8787/securityRealm/addUser and add git
as username and login
as password.
Click on [ Create User ]
.
Add the rights to the git user
Go to the http://localhost:8787/configureSecurity page in your browser. Add the git user to the matrix:
git
in the field User/group to add:
and click on [ Add ]
Now it is time to check the boxes for minimal rights to the git user. Only these are needed:
Make sure that the Prevent Cross Site Request Forgery exploits
checkbox is unchecked and click on [ Save ]
We assume we have the username user
and our git enabled project with the Jenkinsfile
in it is called project
and is located at /home/user/projects/project
In your http://localhost:8787 Jenkins add a new pipeline project. I named it hookpipeline for reference.
New Item
in the Jenkins menuhookpipeline
[ OK ]
Poll SCM
in the Build Triggers section. Leave the Schedule empty.Pipeline script from SCM
Repository URL
field enter [email protected]:projects/project/.git
Script Path
field enter Jenkinsfile
Go to the /home/user/projects/project/.git/hooks
folder and create a file called post-commit
that contains this:
#!/bin/sh
BRANCHNAME=$(git rev-parse --abbrev-ref HEAD)
MASTERBRANCH='master'
curl -XPOST -u git:login http://localhost:8787/job/hookpipeline/build
echo "Build triggered successfully on branch: $BRANCHNAME"
Make this file executable:
$ chmod +x /home/user/projects/project/.git/hooks/post-commit
Test the post-commit hook:
$ /home/user/projects/project/.git/hooks/post-commit
Check in Jenkins if your hookpipeline project was triggered.
Finally make some arbitrary change to your project, add the changes and do a commit. This will now trigger the pipeline in your local Jenkins.
Happy Days!
A few comments:
import sun.misc.*;
Don't do this. It is non-standard and not guaranteed to be the same between implementations. There are other libraries with Base64 conversion available.
byte[] encVal = c.doFinal(Data.getBytes());
You are relying on the default character encoding here. Always specify what character encoding you are using: byte[] encVal = c.doFinal(Data.getBytes("UTF-8"));
Defaults might be different in different places.
As @thegrinner pointed out, you need to explicitly check the length of your byte arrays. If there is a discrepancy, then compare them byte by byte to see where the difference is creeping in.
I got similar error after deleting a subproject, removed

First of all, like Steven Rumbalski said, "PEP8 doesn't address this question", so it is a matter of personal preference.
I would use a similar but not identical format as your format 3. Here is mine, and why.
my_dictionary = { # Don't think dict(...) notation has more readability
"key1": 1, # Indent by one press of TAB (i.e. 4 spaces)
"key2": 2, # Same indentation scale as above
"key3": 3, # Keep this final comma, so that future addition won't show up as 2-lines change in code diff
} # My favorite: SAME indentation AS ABOVE, to emphasize this bracket is still part of the above code block!
the_next_line_of_code() # Otherwise the previous line would look like the begin of this part of code
bad_example = {
"foo": "bar", # Don't do this. Unnecessary indentation wastes screen space
"hello": "world" # Don't do this. Omitting the comma is not good.
} # You see? This line visually "joins" the next line when in a glance
the_next_line_of_code()
btw_this_is_a_function_with_long_name_or_with_lots_of_parameters(
foo='hello world', # So I put one parameter per line
bar=123, # And yeah, this extra comma here is harmless too;
# I bet not many people knew/tried this.
# Oh did I just show you how to write
# multiple-line inline comment here?
# Basically, same indentation forms a natural paragraph.
) # Indentation here. Same idea as the long dict case.
the_next_line_of_code()
# By the way, now you see how I prefer inline comment to document the very line.
# I think this inline style is more compact.
# Otherwise you will need extra blank line to split the comment and its code from others.

Building off of Mamboking's answer:
ContractsDao mock_contractsDao = mock(ContractsDao.class);
when(mock_contractsDao.save(anyString())).thenReturn("Some result");
m_orderSvc.m_contractsDao = mock_contractsDao;
m_prog = new ProcessOrdersWorker(m_orderSvc, m_opportunitySvc, m_myprojectOrgSvc);
m_prog.work();
Addressing your request to verify whether the argument contains a certain value, I could assume you mean that the argument is a String and you want to test whether the String argument contains a substring. For this you could do:
ArgumentCaptor<String> savedCaptor = ArgumentCaptor.forClass(String.class);
verify(mock_contractsDao).save(savedCaptor.capture());
assertTrue(savedCaptor.getValue().contains("substring I want to find");
If that assumption was wrong, and the argument to save()
is a collection of some kind, it would be only slightly different:
ArgumentCaptor<Collection<MyType>> savedCaptor = ArgumentCaptor.forClass(Collection.class);
verify(mock_contractsDao).save(savedCaptor.capture());
assertTrue(savedCaptor.getValue().contains(someMyTypeElementToFindInCollection);
You might also check into ArgumentMatchers, if you know how to use Hamcrest matchers.
Try:
var funcs = [];_x000D_
_x000D_
for (var i = 0; i < 3; i++) {_x000D_
funcs[i] = (function(index) {_x000D_
return function() {_x000D_
console.log("My value: " + index);_x000D_
};_x000D_
}(i));_x000D_
}_x000D_
_x000D_
for (var j = 0; j < 3; j++) {_x000D_
funcs[j]();_x000D_
}

Edit (2014):
Personally I think @Aust's more recent answer about using .bind

i suggest PDFMerger from github.com, so easy like ::

$pdf = new PDFMerger;
$pdf->addPDF('samplepdfs/one.pdf', '1, 3, 4')
->addPDF('samplepdfs/two.pdf', '1-2')
->addPDF('samplepdfs/three.pdf', 'all')
->merge('file', 'samplepdfs/TEST2.pdf'); // REPLACE 'file' WITH 'browser', 'download', 'string', or 'file' for output options
holder.checkbox.setTag(row_id);
and
holder.checkbox.setOnClickListener( new OnClickListener() {
@Override
public void onClick(View v) {
CheckBox c = (CheckBox) v;
int row_id = (Integer) v.getTag();
checkboxes.put(row_id, c.isChecked());
}
});
My best guess at why you had problems with the ----- covering your first result is that you actually read the input line from a file. That line probably had a \r on the end so you ended up with something like this:
-----------test2-------test3
What happened is the machine actually printed this:
test-------test2-------test3\r-------
That means, because of the carriage return at the end of test3, that the dashes after test3 were printed over the top of the first word (and a few of the existing dashes between test and test2 but you wouldn't notice that because they were already dashes).
It is not unusual to find discrepancies between different versions of documentation. Most developers view documentation as a chore, and they tend to put it off.
As a rule of thumb, if the javadoc says one thing and some non-javadoc documentation contradicts it, the chances are that the javadoc is more accurate. Programmers are more likely to keep the javadoc up to date with changes to the code ... because the "source" for the javadoc is in the same file as the code.
In the case of @deprecated
tags, it is a virtual certainty that the javadoc is more accurate. Developers deprecate things after careful consideration ... and (generally speaking) they don't undeprecate them.

FQDN means the resolved name over DNS. It should be like "server-name.search-domain".
The warning you get just provides a notice that httpd can not find a FQDN, so it might not work right to handle a name-based virtual host. So make sure the expected FQDN is registered in your DNS server, or manually add the entry in /etc/hosts
which is prior to hitting DNS.

In adition to Ian Boyd's answer:
Also CultureInfo
implements this interface and can be used in your case. So you could parse a French date string for example; you could use
var ci = new CultureInfo("fr-FR");
DateTime dt = DateTime.ParseExact(yourDateInputString, yourFormatString, ci);
1 = 1 expression is commonly used in generated sql code. This expression can simplify sql generating code reducing number of conditional statements.
You can pass an empty array to unselect all the selection. Here goes an example. From documentation
val()
allows you to pass an array of element values. This is useful when working on a jQuery object containing elements like , , and s inside of a . In this case, the inputs and the options having a value that matches one of the elements of the array will be checked or selected while those having a value that doesn't match one of the elements of the array will be unchecked or unselected, depending on the type.

Regarding GOROOT
specifically, Go 1.9 will set it automatically to its installation path.
Even if you have multiple Go installed, calling the 1.9.x one will set GOROOT
to /path/to/go/1.9
(before, if not set, it assumed a default path like /usr/local/go
or c:\Go
).
See CL Go Review 53370:
The
go tool
will now use the path from which it was invoked to attempt to locate the root of the Go install tree.
This means that if the entire Go installation is moved to a new location, thego tool
should continue to work as usual.This may be overriden by setting
GOROOT
in the environment, which should only be done in unusual circumstances.
Note that this does not affect the result of theruntime.GOROOT()
function, which will continue to report the original installation location; this may be fixed in later releases.

More info:
Late answer but I'll add some additional insight to what has been shared, namely that there are several types of "parameters" to a request, and you should take this into account.
Now let's look at the different places where these parameters could go.
Generally you want State to be set in headers or cookies, depending on what type of state information it is. I think we can all agree on this. Use custom http headers (X-My-Header) if you need to.
Similarly, Content only has one place to belong, which is in the request body, either as query strings or as http multipart and/or JSON content. This is consistent with what you receive from the server when it sends you content. So you shouldn't be rude and do it differently.
Locators such as "id=5" or "action=refresh" or "page=2" would make sense to have as a URL path, such as mysite.com/article/5/page=2
where partly you know what each part is supposed to mean (the basics such as article and 5 obviously mean get me the data of type article with id 5) and additional parameters are specified as part of the URI. They can be in the form of page=2
, or page/2
if you know that after a certain point in the URI the "folders" are paired key-values.
Filters always go in the query string, because while they are a part of finding the right data, they are only there to return a subset or modification of what the Locators return alone. The search in mysite.com/article/?query=Obama
(subset) is a filter, and so is /article/5?order=backwards
(modification). Think about what it does, not just what it's called!
If "view" determines output format, then it is a filter (mysite.com/article/5?view=pdf
) because it returns a modification of the found resource rather than homing in on which resource we want. If it instead decides which specific part of the article we get to see (mysite.com/article/5/view=summary
) then it is a locator.
Remember, narrowing down a set of resources is filtering. Locating something specific within a resource is locating... duh. Subset filtering may return any number of results (even 0). Locating will always find that specific instance of something (if it exists). Modification filtering will return the same data as the locator, except modified (if such a modification is allowed).
Hope this helped give people some eureka moments if they've been lost about where to put stuff!
If you want to do it using Pentaho DI, you can use "Modified JavaScript" Step and write the below function:
dateAdd(d1, "d", -7); // d1 is the current date and "d" is the date identifier
Check the image below: [Assuming current date is : 22 December 2014]
Hope it helps :)
Try data = new int[] {10,20,30,40,50,60,71,80,90,91 };
There are two ways to achieve this.
1- As already proposed u can set the background of your spinner as custom 9 patch Image with all the adjustments made into it .
android:background="@drawable/btn_dropdown"
android:clickable="true"
android:dropDownVerticalOffset="-10dip"
android:dropDownHorizontalOffset="0dip"
android:gravity="center"
If you want your Spinner to show With various different background colors i would recommend making the drop down image transparent, & loading that spinner in a relative layout with your color set in.
btn _dropdown is as:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_window_focused="false" android:state_enabled="true"
android:drawable="@drawable/spinner_default" />
<item
android:state_window_focused="false" android:state_enabled="false"
android:drawable="@drawable/spinner_default" />
<item
android:state_pressed="true"
android:drawable="@drawable/spinner_pressed" />
<item
android:state_focused="true" android:state_enabled="true"
android:drawable="@drawable/spinner_pressed" />
<item
android:state_enabled="true"
android:drawable="@drawable/spinner_default" />
<item
android:state_focused="true"
android:drawable="@drawable/spinner_pressed" />
<item
android:drawable="@drawable/spinner_default" />
</selector>
where the various states of pngwould define your various States of spinner seleti
In my case, cleaning and rebuilding the project resolved the problem.
java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;
That method was added in Servlet 2.5.
So this problem can have at least 3 causes:
web.xml
is not declared conform Servlet 2.5 or newer.To solve it,
web.xml
complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.servlet-api.jar
or j2ee.jar
in /WEB-INF/lib
or even worse, the JRE/lib
or JRE/lib/ext
. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.Wait -- did you actually mean that "the same number of rows ... are being processed" or that "the same number of rows are being returned"? In general, the outer join would process many more rows, including those for which there is no match, even if it returns the same number of records.
I (being people myself) wrote this statement because I wanted to detect the key which the user typed on the keyboard across different browsers.
In firefox for example, characters have > 0 charCode and 0 keyCode, and keys such as arrows & backspace have > 0 keyCode and 0 charCode.
However, using this statement can be problematic as "collisions" are possible. For example, if you want to distinguish between the Delete and the Period keys, this won't work, as the Delete has keyCode = 46 and the Period has charCode = 46.
powershell + sqlcmd :)
In addition to the other answers, there is also the TimeUnit class which allows you to convert one time duration to another. For example, to find out how many milliseconds make up one day:
TimeUnit.MILLISECONDS.convert(1, TimeUnit.DAYS); //gives 86400000
Note that this method takes a long
, so if you have a fraction of a day, you will have to multiply it by the number of milliseconds in one day.
when you pass an object within curly braces as an argument to a function with one parameter , you're assigning this object to a variable which is the parameter in this case
You can use the CSS3 Linear Gradient property along with your background-image like this:
#landing-wrapper {
display:table;
width:100%;
background: linear-gradient( rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5) ), url('landingpagepic.jpg');
background-position:center top;
height:350px;
}
Here's a demo:
#landing-wrapper {_x000D_
display: table;_x000D_
width: 100%;_x000D_
background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), url('http://placehold.it/350x150');_x000D_
background-position: center top;_x000D_
height: 350px;_x000D_
color: white;_x000D_
}

I spotted half of the problem: I can't use the 'indexer' notation to objects (my_object[0]). Is there a way to bypass it?
No; an object literal, as the name implies, is an object, and not an array, so you cannot simply retrieve a property based on an index, since there is no specific order of their properties. The only way to retrieve their values is by using the specific name:
var someVar = options.filters.firstName; //Returns 'abc'
Or by iterating over them using the for ... in
loop:
for(var p in options.filters) {
var someVar = options.filters[p]; //Returns the property being iterated

Make sure you have the projects targeting the same framework version. Most of the times the reason would be that current project ( where you are adding reference of another project ) points to a different .net framework version than the rest ones.
What was asked for was to set:
the 'default', not some other color profile, and
'for all vim sessions', not simply for the current user.
The default colorscheme, "for all vim sessions", is not set simply by adding a line to your ~/.vimrc
, as all of the other answers here say, nor is the default set without the word 'default' being there.
So all of the other answers here, so far, get both of these wrong. (lol, how did that happen?)
The correct answer is:
Add a line to your system vim setup file in /etc/vim/
that says
colorscheme default
or using the abbreviation
colo default
but not capitalized as
colo Default
(I suggest using the full, un-abbreviated term 'colorscheme', so that when you look at this years later you'll be able to more easily figure out what that darn thing does. I would also put a comment above it like "Use default colors for vim"
.)
To append that correctly, first look at your /etc/vim/vimrc
file.
At the bottom of mine, I see these lines which include /etc/vim/vimrc.local
:
" Source a global configuration file if available
if filereadable("/etc/vim/vimrc.local")
source /etc/vim/vimrc.local
endif
So you can append this line to either of these two files.
I think the best solution is to append your line to /etc/vim/vimrc.local
like this:
colorscheme default
You can easily do that in bash with this line:
$ echo -e "\"Use default colors for vim:\ncolorscheme default" \
| sudo tee -a /etc/vim/vimrc.local
#
# NOTE: This doesn't work:
#
# $ sudo echo 'colorscheme default' >> /etc/vim/vimrc.local
#
# It's the same general idea, and simpler, but because sudo doesn't
# know how to handle pipes, it fails with a `Permission denied` error.
Also check that you have permission to globally read this file:
sudo chmod 644 /etc/vim/vimrc.local
With $ tail /etc/vim/vimrc.local
you should now see these lines:
"Use default colors for vim:
colorscheme default
If your Python interpreter is old (1.5.2, for example, which is common on some older Linux distributions), you may not have join()
available as a method on any old string object, and you will instead need to use the string module. Example:
a = ['a', 'b', 'c', 'd']
try:
b = ''.join(a)
except AttributeError:
import string
b = string.join(a, '')
The string b
will be 'abcd'
.
You need to import the map
operator:
import 'rxjs/add/operator/map'
Or more generally:
import 'rxjs/Rx';
Notice: For versions of RxJS 6.x.x
and above, you will have to use pipeable operators as shown in the code snippet below:
import { map } from 'rxjs/operators';
import { HttpClient } from '@angular/common/http';
// ...
export class MyComponent {
constructor(private http: HttpClient) { }
getItems() {
this.http.get('https://example.com/api/items').pipe(map(data => {})).subscribe(result => {
console.log(result);
});
}
}
This is caused by the RxJS team removing support for using See the breaking changes in RxJS' changelog for more info.
From the changelog:
operators: Pipeable operators must now be imported from rxjs like so:
import { map, filter, switchMap } from 'rxjs/operators';
. No deep imports.
You should get the array like in $_POST['id']. So you should be able to do this:
foreach ($_POST['id'] as $key => $value) {
echo $value . "<br />";
}
Input names should be same:
<input name='id[]' type='checkbox' value='1'>
<input name='id[]' type='checkbox' value='2'>
...
In addition what others mentioned here, note that combining the Application.DispatcherUnhandledException
(and its similars) with
<configuration>
<runtime>
<legacyUnhandledExceptionPolicy enabled="1" />
</runtime>
</configuration>
in the app.config
will prevent your secondary threads exception from shutting down the application.
In your application android manifest file, under the application tag you can try several of these themes.
Replace
<application
android:theme="@style/AppTheme" >
with different themes defined by the android system. They can be like:-
android:theme="@android:style/Theme.Black"
android:theme="@android:style/Theme.DeviceDefault"
android:theme="@android:style/Theme.DeviceDefault.Dialog"
android:theme="@android:style/Theme.Holo"
android:theme="@android:style/Theme.Translucent"
Each of these themes will have a different effect on your application like the DeviceDefault.Dialog will make your application look like a dialog box. You should try more of these. You can have a look from the android sdk or simply use auto complete in Eclipse IDE to explore the various available options.
A correct way to define your own theme would be to edit the styles.xml
file present in the resources folder of your application.
Try using rowMeans
:
z$mean=rowMeans(z[,c("x", "y")], na.rm=TRUE)
w x y mean
1 5 1 1 1
2 6 2 2 2
3 7 3 3 3
4 8 4 NA 4

Implode will combine an array into a string for you, but to make an SQL query out a kay/value pair you'll have to write your own function.
Different tools may interpret the meaning of @Nullable
differently. For example, the Checker Framework and FindBugs handle @Nullable
differently.
You can manually create the subplots with matplotlib, and then plot the dataframes on a specific subplot using the ax
keyword. For example for 4 subplots (2x2):
import matplotlib.pyplot as plt
fig, axes = plt.subplots(nrows=2, ncols=2)
df1.plot(ax=axes[0,0])
df2.plot(ax=axes[0,1])
...
Here axes
is an array which holds the different subplot axes, and you can access one just by indexing axes
.
If you want a shared x-axis, then you can provide sharex=True
to plt.subplots
.
LDF holds the transaction log. If you set your backups correctly - it will be small. It it grows - you have a very common problem of setting database recovery mode to FULL and then forgetting to backup the transaction log (LDF file). Let me explain how to fix it.
Some would suggest to use SHRINKFILE to trim you log. Note that this is OK only as an exception. If you do it regularly, it defeats the purpose of FULL recovery model: first you go into trouble of saving every single change in the log, then you just dump it. Set recovery mode to SIMPLE instead.
With my mercurial background I was going to use:
git log --patch -1 $ID > $file
But I am considering using git format-patch -1 $ID
now.
This is my favourite way of doing the command line, especially, but definitely not only when efficiency is an issue. It might seem overkill, but I think there are few disadvantages to this overkill.
Use gperf for efficient C/C++ command line processing
Disadvantages:
Advantages:
Using an IDE like eclipse you can probably automate the process of running gperf, so the only thing you would have to do is add an option to the config file and to your switch statement and press build...
I used a batch file to run gperf and do some cleanup and add include guards with sed (on the gperf generated .hpp file)...
So, extremely concise and clean code within your software and one auto-generated hash table file that you don't really need to change manually. I doubt if boost::program_options actually would beat that even without efficiency as a priority.
In my case, I developped the client and the server side, and I have the exception :
Cause : error marshalling arguments; nested exception is: java.net.SocketException: Software caused connection abort: socket write error
when classes in client and server are different. I don't download server's classes (Interfaces) on the client, I juste add same files in the project. But the path must be exactly the same. For example, on the server project I have java\rmi\services packages with some serviceInterface and implementations, I have to create the same package on the client project. If I change it by java/rmi/server/services for example, I get the above exception. Same exception if the interface version is different between client and server (even with an empty row added inadvertently ... I think rmi makes a sort of hash of classes to check version ... I don't know... If it could help ...
My issue was having multiple AWS credentials; default and dev. Since I was trying to deploy to dev this worked:
$(aws ecr get-login --no-include-email --region eu-west-1 --profile dev | sed 's|https://||')
Presumably, those columns are integer columns - which will be the reason as the result of the calculation will be of the same type.
e.g. if you do this:
SELECT 1 / 2
you will get 0, which is obviously not the real answer. So, convert the values to e.g. decimal and do the calculation based on that datatype instead.
e.g.
SELECT CAST(1 AS DECIMAL) / 2
gives 0.500000

Java 8 Update
Java 8 introduces the following packages for time and date manipulation.
java.time.*;
java.time.format.*;
java.time.chono.*;
java.time.temporal.*;
java.time.zone.*;
These are more organized and intuitive.
We need only top two packages for the discussion.
There are 3 top level classes - LocalDate
, LocalTime
, LocalDateTime
for describing Date, Time and DateTime respectively. Although, they are formatted properly in toString()
, each class has format method which accepts DateTimeFormatter
to format in customized way.
DateTimeFormatter
can also be used show the date given a day. It has few
import java.time.*;
import java.time.format.*;
class DateTimeDemo{
public static void main(String...args){
LocalDateTime x = LocalDateTime.now();
System.out.println(x.format(DateTimeFormatter.ofLocalizedDate(FormatStyle.FULL)));//Shows Day and Date.
System.out.println(x.format(DateTimeFormatter.ofPattern("EE")));//Short Form
System.out.println(x.format(DateTimeFormatter.ofPattern("EEEE")));//Long Form
}
}
ofLocalizedTime
accepts FormatStyle
which is an enumeration in java.time.format
ofPattern
accepts String
with restricted pattern characters of restricted length. Here are the characters which can be passed into the toPattern
method.
You can try different number of patterns to see how the output will be.
Check out more about Java 8 DateTime API here
Better to get rid of DST, Math.ceil, Math.floor etc. by using UTC times:
var firstDate = Date.UTC(2015,01,2);
var secondDate = Date.UTC(2015,04,22);
var diff = Math.abs((firstDate.valueOf()
- secondDate.valueOf())/(24*60*60*1000));
This example gives difference 109 days. 24*60*60*1000
is one day in milliseconds.

You use the lpMultiByteStr [out] parameter by creating a new char array. You then pass this char array in to get it filled. You only need to initialize the length of the string + 1 so that you can have a null terminated string after the conversion.
Here are a couple of useful helper functions for you, they show the usage of all parameters.
#include <string>
std::string wstrtostr(const std::wstring &wstr)
{
// Convert a Unicode string to an ASCII string
std::string strTo;
char *szTo = new char[wstr.length() + 1];
szTo[wstr.size()] = '\0';
WideCharToMultiByte(CP_ACP, 0, wstr.c_str(), -1, szTo, (int)wstr.length(), NULL, NULL);
strTo = szTo;
delete[] szTo;
return strTo;
}
std::wstring strtowstr(const std::string &str)
{
// Convert an ASCII string to a Unicode String
std::wstring wstrTo;
wchar_t *wszTo = new wchar_t[str.length() + 1];
wszTo[str.size()] = L'\0';
MultiByteToWideChar(CP_ACP, 0, str.c_str(), -1, wszTo, (int)str.length());
wstrTo = wszTo;
delete[] wszTo;
return wstrTo;
}

Anytime in documentation when you see that it has a parameter which is a pointer to a type, and they tell you it is an out variable, you will want to create that type, and then pass in a pointer to it. The function will use that pointer to fill your variable.
So you can understand this better:
//pX is an out parameter, it fills your variable with 10.
void fillXWith10(int *pX)
{
*pX = 10;
}
int main(int argc, char ** argv)
{
int X;
fillXWith10(&X);
return 0;
}
You can create separate tags using the .jquery()
method. And create child tags by using the .append()
method. As jQuery supports chaining, you can also apply CSS in two ways.
Either specify it in the class or just call .attr()
:
var lTag = jQuery("<li/>")
.appendTo(".div_class").html(data.productDisplayName);
var aHref = jQuery('<a/>',{
}).appendTo(lTag).attr("href", data.mediumImageURL);
jQuery('<img/>',{
}).appendTo(aHref).attr("src", data.mediumImageURL).attr("alt", data.altText);
Firstly I am appending a list tag to my div tag and inserting JSON data into it. Next, I am creating a child tag of list, provided some attribute. I have assigned the value to a variable, so that it would be easy for me to append it.
while i do also like the answer posted by @Alex, i offer this variation to @Graham's solution above
this exclusively uses record existence in the INSERTED and UPDATED tables, as opposed to using COLUMNS_UPDATED for the first test. It also provides the paranoid programmer relief knowing that the final case has been considered...
declare @action varchar(4)
IF EXISTS (SELECT * FROM INSERTED)
BEGIN
IF EXISTS (SELECT * FROM DELETED)
SET @action = 'U' -- update
ELSE
SET @action = 'I' --insert
END
ELSE IF EXISTS (SELECT * FROM DELETED)
SET @action = 'D' -- delete
else
set @action = 'noop' --no records affected
--print @action
you will get NOOP with a statement like the following :
update tbl1 set col1='cat' where 1=2
from https://docs.angularjs.org/api/ng/function/angular.element
angular.element
wraps a raw DOM element or HTML string as a jQuery element (If jQuery is not available, angular.element delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite.")
So you simply could do:
angular.module('myApp.filters', []).
filter('htmlToPlaintext', function() {
return function(text) {
return angular.element(text).text();
}
}
);
Usage:
<div>{{myText | htmlToPlaintext}}</div>
For a Node.js app, in the server.js file before registering all of my own routes, I put the code below. It sets the headers for all responses. It also ends the response gracefully if it is a pre-flight "OPTIONS" call and immediately sends the pre-flight response back to the client without "nexting" (is that a word?) down through the actual business logic routes. Here is my server.js file. Relevant sections highlighted for Stackoverflow use.
// server.js
// ==================
// BASE SETUP
// import the packages we need
var express = require('express');
var app = express();

// ====================================================
// configure app to use bodyParser()
// this will let us get the data from a POST
app.use(bodyParser.urlencoded({ extended: true }));

Python 3 includes an improved super() which allows use like this:

Note that HTTP doesn't typically keep TCP connections open for any longer than it takes to transmit the page to the client; and it usually takes much more time for the user to read a web page than it takes to download the page... while the user is viewing the page, he adds no load to the server at all.
So the number of people that can be simultaneously viewing your web site is much larger than the number of TCP connections that it can simultaneously serve.
If you only want to sort only on the 5th field then use -k5,5
.
Also, use the -t
command line switch to specify the delimiter to tab
. Try this:
sort -k5,5 -r -n -t \t filename
or if the above doesn't work (with the tab
) this:
sort -k5,5 -r -n -t $'\t' filename
The man page for sort states:
-t, --field-separator=SEP use SEP instead of non-blank to blank transition
Finally, this SO question Unix Sort with Tab Delimiter might be helpful.
I tried many of the methods here, but they were either complicated or didn't quite meet my requirements. In fact, one can write a helper method quite simply:
public class ExceptionAssertions {
public static void assertException(BlastContainer blastContainer ) {
boolean caughtException = false;
try {
blastContainer.test();
} catch( Exception e ) {
caughtException = true;
}
if( !caughtException ) {
throw new AssertionFailedError("exception expected to be thrown, but was not");
}
}
public static interface BlastContainer {
public void test() throws Exception;
}
}
Use it like this:
assertException(new BlastContainer() {
@Override
public void test() throws Exception {
doSomethingThatShouldExceptHere();
}
});
Zero dependencies: no need for mockito, no need powermock; and works just fine with final classes.
The ARM is like an Italian sports car:
The x86 is like an American muscle car:
In summary: the x86 is based on a design from 1974 and is good in a straight line (but uses a lot of fuel). The arm uses little fuel, does not slowdown for corners (branches).
Metaphor over, here are some real differences.
Based on Ivan Laharnar with less code and simplier:
declare
lastSeq number;
begin
SELECT MAX(ID) + 1 INTO lastSeq FROM <TABLE_NAME>;
if lastSeq IS NULL then lastSeq := 1; end if;
execute immediate 'CREATE SEQUENCE <SEQUENCE_NAME> INCREMENT BY 1 START WITH ' || lastSeq || ' MAXVALUE 999999999 MINVALUE 1 NOCACHE';
end;
A short (but perhaps not the fastest) way to do this would be to use base r, since a data frame is just a list of equal length vectors. Thus the conversion between your input list and a 30 x 132 data.frame would be:
df <- data.frame(l)
From there we can transpose it to a 132 x 30 matrix, and convert it back to a dataframe:
new_df <- data.frame(t(df))
As a one-liner:
new_df <- data.frame(t(data.frame(l)))
The rownames will be pretty annoying to look at, but you could always rename those with
rownames(new_df) <- 1:nrow(new_df)
I use Eclipse Java EE edition
Create a "Dynamic Web Project"
Install a local server in the server view, for the version of Tomcat I'm using. Then debug, and run on that server for testing.
When I deploy I export the project to a war file.
#include <stdio.h>
#include <time.h>
void main()
{
time_t t;
time(&t);
clrscr();
printf("Today's date and time : %s",ctime(&t));
getch();
}
==
and !=
do not take into account the data type of the variables you compare. So these would all return true:
'0' == 0
false == 0
NULL == false
===
and !==
do take into account the data type. That means comparing a string to a boolean will never be true because they're of different types for example. These will all return false:
'0' === 0
false === 0
NULL === false
You should compare data types for functions that return values that could possibly be of ambiguous truthy/falsy value. A well-known example is strpos()
:
// This returns 0 because F exists as the first character, but as my above example,
// 0 could mean false, so using == or != would return an incorrect result
var_dump(strpos('Foo', 'F') != false); // bool(false)
var_dump(strpos('Foo', 'F') !== false); // bool(true), it exists so false isn't returned

For website developers, another option you have is to follow a working Facebook Graph API tutorial such as this one.
But if you need a quick solution where you can customize and embed a Facebook page feed instantly, you should use website plugins such as this one.
Here's a step by step guide:
Visit the tutorial link to see a live demo there as well.
shift
can be used in places where you want to get the first element (index=0
) of an array and chain with other array methods.
example:
const comps = [{}, {}, {}]
const specComp = comps
.map(fn1)
.filter(fn2)
.shift()
Remember shift
mutates the array, which is very different from accessing via an indexer.
Try this:
$('#contra').focusout(function (){
$('#btnPassword').focus();
});
As Paul Turner answered Socket.Connected
cannot be used in this situation. You need to poll connection every time to see if connection is still active. This is code I used:
bool SocketConnected(Socket s)
{
bool part1 = s.Poll(1000, SelectMode.SelectRead);
bool part2 = (s.Available == 0);
if (part1 && part2)
return false;
else
return true;
}
It works like this:
s.Poll
returns true if
s.Available
returns number of bytes available for readingnormally I extract the embedded image with 'pdfimages' at the native resolution, then use ImageMagick's convert to the needed format:
$ pdfimages -list fileName.pdf
$ pdfimages fileName.pdf fileName # save in .ppm format
$ convert fileName-000.ppm fileName-000.png
this generate the best and smallest result file.
Note: For lossy JPG embedded images, you had to use -j:
$ pdfimages -j fileName.pdf fileName # save in .jpg format
With recent poppler you can use -all that save lossy as jpg and lossless as png
On little provided Win platform you had to download a recent (0.37 2015) 'poppler-util' binary from: http://blog.alivate.com.au/poppler-windows/

There are already multiple answers and formatting types for SQL server 2008. But this method somewhat ambiguous and it would be difficult for you to remember the number with respect to Specific Date Format. That's why in next versions of SQL server there is better option.
FORMAT ( value, format [, culture ] )
With culture option, you can specify date as per your viewers.
DECLARE @d DATETIME = '10/01/2011';
SELECT FORMAT ( @d, 'd', 'en-US' ) AS 'US English Result'
,FORMAT ( @d, 'd', 'en-gb' ) AS 'Great Britain English Result'

For OP's solution, we can use following format, which is already mentioned by @Martin Smith:
FORMAT(GETDATE(), 'dd/MMM/yyyy', 'en-us')
Some sample date formats:
If you want more date formats of SQL server, you should visit:
I have been looking into the same problem! I think your problem is related to where you identify the variable that you use to populate the ArrayList that you return. If you define it inside the loop, then it will always reference the last row in the table in the database. In order to avoid this, you have to identify it outside the loop:
String name;
if (cursor.moveToFirst()) {
while (cursor.isAfterLast() == false) {
name = cursor.getString(cursor
.getColumnIndex(countyname));
list.add(name);
cursor.moveToNext();
}
}
Assuming it's a server control, you can use Request["ButtonName"]
To see if a specific button was clicked: if (Request["ButtonName"] != null)
Adding a few thoughts as other answers helped, but were not exact fit.
First of all, as mentioned in accepted answer, edit
/etc/ssh/sshd_config
and set log level:
LogLevel DEBUG3
Then try to authenticate, and when it fails, look for log file:
/var/log/secure
It will have errors you are looking for.
This should work...
var displayDate = new Date().toLocaleDateString();
alert(displayDate);
But I suspect you are trying it on something else, for example:
var displayDate = Date.now.toLocaleDateString(); // No!
alert(displayDate);
I had similar error: "Expecting value: line 1 column 1 (char 0)"
It helped for me to add "myfile.seek(0)", move the pointer to the 0 character
with open(storage_path, 'r') as myfile:
if len(myfile.readlines()) != 0:
myfile.seek(0)
Bank_0 = json.load(myfile)
You can have many java versions in your system.
I think you should add the java 8 in yours JREs installed or edit.
Take a look my screen:
If you click in edit (check your java 8 path):
You can use this repo: GSBorderLabel
It's quite simple:
GSBorderLabel *myLabel = [[GSBorderLabel alloc] initWithTextColor:aColor
andBorderColor:anotherColor
andBorderWidth:2];
Had a similar situation myself. I think it is best to create the tar elsewhere and then use -C to tell tar the base directory for the compressed files. Example:
tar -cjf workspace.tar.gz -C <path_to_workspace> $(ls -A <path_to_workspace>)
This way there is no need to exclude your own tarfile. As noted in other comments, -A will list hidden files.

I had the same "TypeError: an integer is required" error message when attempting to write. Thanks, the .encode() solved it for me. I'm running python 3.4 on a Dell D530 running 32 bit Windows XP Pro.
I'm omitting the com port settings here:
>>>import serial
>>>ser = serial.Serial(5)
>>>ser.close()
>>>ser.open()
>>>ser.write("1".encode())
1
>>>
Option 1
You could also solve it by adding a transparent border to the row (tr), like this
HTML
<table>
<tr>
<td>1</td>
</tr>
<tr>
<td>2</td>
</tr>
</table>
CSS
tr {
border-top: 12px solid transparent;
border-bottom: 12px solid transparent;
}
Works like a charm, although if you need regular borders, then this method will sadly not work.
Option 2
Since rows act as a way to group cells, the correct way to do this, would be to use
table {
border-collapse: inherit;
border-spacing: 0 10px;
}
You don't have to uninstall the Google Play version if App Signing by Google Play is enabled for your app, follow the steps:
1. Make a signed version of your app with your release key
2. Go to Google Play Developer console
3. Create a closed track release (alpha or beta release) with the new signed version of your app
4. You can now download the apk signed by App Signing by Google Play, choose derived APK
The reason is App Signing by Google Play signs release apps with different keys, if you have an app installed from Play Store, and you want to test the new release version app (generated from Android Studio) in your phone, "App not installed" happens since the old version and the new version were signed by two different keys: one with App Signing by Google Play and one with your key.
Try this:
protected void Button1_Click(object sender, EventArgs e)
{
SqlConnection cn = new SqlConnection("Data Source=(LocalDB)\\v11.0;AttachDbFilename=|DataDirectory|\\Database.mdf;Integrated Security=True");
try
{
cn.Open();
SqlCommand cmd = new SqlCommand("create table Employee (empno int,empname varchar(50),salary money);", cn);
cmd.ExecuteNonQuery();
lblAlert.Text = "SucessFully Connected";
cn.Close();
}
catch (Exception eq)
{
lblAlert.Text = eq.ToString();
}
}
Firebase now supports multiple application ids with one google-services.json file.
This blog post describes it in detail.
You'll create one parent project in Firebase that you'll use for all of your variants. You then create separate Android applications in Firebase under that project for each application id that you have.
When you created all of your variants, you can download a google-services.json that supports all of your applications ids. When it's relevant to see the data separately (i.e. Crash Reporting) you can toggle that with a dropdown.
Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/
according to documentation you should just
{ path: '**', component: DefaultLayoutComponent }
on your app-routing.module.ts source: https://angular.io/guide/router
There is no built-in date-only type in .NET.
The convention is to use a DateTime
with the time portion set to midnight.
The static DateTime.Today
property will give you today's date.
playSound is a static method in your class, but you are referring to members like audioSounds
or minTime
which are not declared static
so they would require a SoundManager sm = new SoundManager();
to operate as sm.audioSounds
or sm.minTime
respectively
Solution:
public static List<AudioSource> audioSounds = new List<AudioSource>();
public static double minTime = 0.5;
It is “old-fashioned” way to specify ranges of revisions you wish to merge. With 1.5+ you can use:
svn merge HEAD url/of/trunk path/to/branch/wc
To change the size of (almost) all text elements, in one place, and synchronously, rel()
is quite efficient:
g+theme(text = element_text(size=rel(3.5))
You might want to tweak the number a bit, to get the optimum result. It sets both the horizontal and vertical axis labels and titles, and other text elements, on the same scale. One exception is faceted grids' titles which must be manually set to the same value, for example if both x and y facets are used in a graph:
theme(text = element_text(size=rel(3.5)),
strip.text.x = element_text(size=rel(3.5)),
strip.text.y = element_text(size=rel(3.5)))
I had the same problem and couldn't figure it out for almost a day. I added IUSR and NetworkService to the folder permissions, I made sure it was running as NetworkService. I tried impersonation and even running as administrator (DO NOT DO THIS). Then someone recommended that I try running the page from inside the Windows 2008 R2 server and it pointed me to the Handler Mappings, which were all disabled.
I got it to work with this:
Now try refreshing your website.
var select = new SelectElement(elementX);
select.MoveToElement(elementX).Build().Perform();
var click = (
from sel in select
let value = "College"
select value
);
Select
is a transformation, not an action, so it is lazily evaluated (won't actually do the calculations just map the operations). Collect
is an action.
Try:
df.limit(20).collect()
allow_url_fopen
is generally set to On.
If it is not On, then you can try two things.
Create an .htaccess
file and keep it in root folder ( sometimes it may need to place it one step back folder of the root) and paste this code there.
php_value allow_url_fopen On
Create a php.ini
file (for update server php5.ini
) and keep it in root folder (sometimes it may need to place it one step back folder of the root) and paste the following code there:
allow_url_fopen = On;
I have personally tested the above solutions; they worked for me.
When you specify position:absolute it positions itself to the next-highest element with position:relative. In this case, that's the .project div.
If you give the image's immediate parent div a style of position:relative, the overlay will key to that instead of the div which includes the text. For example: http://jsfiddle.net/7gYUU/1/
<div class="parent">
<img src="http://placehold.it/500x500" class="img-responsive"/>
<div class="fa fa-plus project-overlay"></div>
</div>
.parent {
position: relative;
}
My solution for what it's worth... considered switching to Castle Windsor as can't say I liked any of the solutions above. Sorry!!

The easiest way is to create an UIImageView subclass (I have tried it and it's working perfectly on iPhone 7 and XCode 8):
class CIRoundedImageView: UIImageView {
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
override func awakeFromNib() {
self.layoutIfNeeded()
layer.cornerRadius = self.frame.height / 2.0
layer.masksToBounds = true
}
}
and then you can also set a border:
imageView.layer.borderWidth = 2.0
imageView.layer.borderColor = UIColor.blackColor().CGColor
I know there's an answer already, but if you want your input to behave exactly like the maxlength
attribute or as close as you can, use the following code:
(function($) {
methods = {
/*
* addMax will take the applied element and add a javascript behavior
* that will set the max length
*/
addMax: function() {
// set variables
var
maxlAttr = $(this).attr("maxlength"),
maxAttR = $(this).attr("max"),
x = 0,
max = "";
// If the element has maxlength apply the code.
if (typeof maxlAttr !== typeof undefined && maxlAttr !== false) {
// create a max equivelant
if (typeof maxlAttr !== typeof undefined && maxlAttr !== false){
while (x < maxlAttr) {
max += "9";
x++;
}
maxAttR = max;
}
// Permissible Keys that can be used while the input has reached maxlength
var keys = [
8, // backspace
9, // tab
13, // enter
46, // delete
37, 39, 38, 40 // arrow keys<^>v
]
// Apply changes to element
$(this)
.attr("max", maxAttR) //add existing max or new max
.keydown(function(event) {
// restrict key press on length reached unless key being used is in keys array or there is highlighted text
if ($(this).val().length == maxlAttr && $.inArray(event.which, keys) == -1 && methods.isTextSelected() == false) return false;
});;
}
},
/*
* isTextSelected returns true if there is a selection on the page.
* This is so that if the user selects text and then presses a number
* it will behave as normal by replacing the selection with the value
* of the key pressed.
*/
isTextSelected: function() {
// set text variable
text = "";
if (window.getSelection) {
text = window.getSelection().toString();
} else if (document.selection && document.selection.type != "Control") {
text = document.selection.createRange().text;
}
return (text.length > 0);
}
};
$.maxlengthNumber = function(){
// Get all number inputs that have maxlength
methods.addMax.call($("input[type=number]"));
}
})($)
// Apply it:
$.maxlengthNumber();
I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer
Assuming we're working with strings here, here's another "elegant" solution using IndexOf()
.
public IQueryable<FACILITY_ITEM> GetFacilityItemRootByDescription(string description)
{
return this.ObjectContext.FACILITY_ITEM
.Where(fi => fi.DESCRIPTION
.IndexOf(description, StringComparison.OrdinalIgnoreCase) != -1);
}
In general, a developer should never throw a NullPointerException. This exception is thrown by the runtime when code attempts to dereference a variable who's value is null. Therefore, if your method wants to explicitly disallow null, as opposed to just happening to have a null value raise a NullPointerException, you should throw an IllegalArgumentException.
You still need to add
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
</plugin>
</plugins>
in your build, because pluginManagement
is only a way to share the same plugin configuration across all your project modules.
From Maven documentation:
pluginManagement: is an element that is seen along side plugins. Plugin Management contains plugin elements in much the same way, except that rather than configuring plugin information for this particular project build, it is intended to configure project builds that inherit from this one. However, this only configures plugins that are actually referenced within the plugins element in the children. The children have every right to override pluginManagement definitions.
Python lists are mutable objects and here:
plot_data = [[]] * len(positions)
you are repeating the same list len(positions)
times.
>>> plot_data = [[]] * 3
>>> plot_data
[[], [], []]
>>> plot_data[0].append(1)
>>> plot_data
[[1], [1], [1]]
>>>
Each list in your list is a reference to the same object. You modify one, you see the modification in all of them.
If you want different lists, you can do this way:
plot_data = [[] for _ in positions]
for example:
>>> pd = [[] for _ in range(3)]
>>> pd
[[], [], []]
>>> pd[0].append(1)
>>> pd
[[1], [], []]
You can not "attach" a SASS/SCSS file to an HTML document.
SASS/SCSS is a CSS preprocessor that runs on the server and compiles to CSS code that your browser understands.
There are client-side alternatives to SASS that can be compiled in the browser using javascript such as LESS CSS, though I advise you compile to CSS for production use.
It's as simple as adding 2 lines of code to your HTML file.
<link rel="stylesheet/less" type="text/css" href="styles.less" />
<script src="less.js" type="text/javascript"></script>
Given a list:
var list = new List<Child>()
{
new Child()
{School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "John"},
new Child()
{School = "School2", FavoriteColor = "blue", Friend = "Bob", Name = "Pete"},
new Child()
{School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "Fred"},
new Child()
{School = "School2", FavoriteColor = "blue", Friend = "Fred", Name = "Bob"},
};
The query would look like:
var newList = list
.GroupBy(x => new {x.School, x.Friend, x.FavoriteColor})
.Select(y => new ConsolidatedChild()
{
FavoriteColor = y.Key.FavoriteColor,
Friend = y.Key.Friend,
School = y.Key.School,
Children = y.ToList()
}
);
Test code:
foreach(var item in newList)
{
Console.WriteLine("School: {0} FavouriteColor: {1} Friend: {2}", item.School,item.FavoriteColor,item.Friend);
foreach(var child in item.Children)
{
Console.WriteLine("\t Name: {0}", child.Name);
}
}
Result:
School: School1 FavouriteColor: blue Friend: Bob
Name: John
Name: Fred
School: School2 FavouriteColor: blue Friend: Bob
Name: Pete
School: School2 FavouriteColor: blue Friend: Fred
Name: Bob
you can get all product information from following code
$product_id=6//Suppose
$_product=Mage::getModel('catalog/product')->load($product_id);
$product_data["id"]=$_product->getId();
$product_data["name"]=$_product->getName();
$product_data["short_description"]=$_product->getShortDescription();
$product_data["description"]=$_product->getDescription();
$product_data["price"]=$_product->getPrice();
$product_data["special price"]=$_product->getFinalPrice();
$product_data["image"]=$_product->getThumbnailUrl();
$product_data["model"]=$_product->getSku();
$product_data["color"]=$_product->getAttributeText('color'); //get cusom attribute value
$storeId = Mage::app()->getStore()->getId();
$summaryData = Mage::getModel('review/review_summary')->setStoreId($storeId) ->load($_product->getId());
$product_data["rating"]=($summaryData['rating_summary']*5)/100;
$product_data["shipping"]=Mage::getStoreConfig('carriers/flatrate/price');
if($_product->isSalable() ==1)
$product_data["in_stock"]=1;
else
$product_data["in_stock"]=0;
echo "<pre>";
print_r($product_data);
//echo "</pre>";
From my experience event.stopPropagation() is mostly used in CSS effect or animation works, for instance when you have hover effect for both card and button element, when you hover on the button both card and buttons hover effect will be triggered in this case, you can use event.stopPropagation() stop bubbling actions, and event.preventDefault() is for prevent default behaviour of browser actions. For instance, you have form but you only defined click event for the submit action, if the user submits the form by pressing enter, the browser triggered by keypress event, not your click event here you should use event.preventDefault() to avoid inappropriate behavior. I don't know what the hell is return false; sorry.For more clarification visit this link and play around with line #33 https://www.codecademy.com/courses/introduction-to-javascript/lessons/requests-i/exercises/xhr-get-request-iv
Have you tried overflow-y:auto
? It is not exactly what you want, as the scrollbar will appear only when needed.
There is OxyPlot which I recommend. It has packages for WPF, Metro, Silverlight, Windows Forms, Avalonia UI, XWT. Besides graphics it can export to SVG, PDF, Open XML, etc. And it even supports Mono and Xamarin for Android and iOS. It is actively developed too.
There is also a new (at least for me) open source .NET plotting library called Live-Charts. The plots are pretty interactive. Library suports WPF, WinForms and UWP. Xamarin is planned. The design is made towards MV* patterns. But @Pawel Audionysos suggests not such a good performance of Live-Charts WPF.
This is for fecha(TEXT) format date YYYY-MM-dd HH:mm:ss for instance I want all the records of Ene-05-2014 (2014-01-05):
SELECT
fecha
FROM
Mytable
WHERE
DATE(substr(fecha ,1,4) ||substr(fecha ,6,2)||substr(fecha ,9,2))
BETWEEN
DATE(20140105)
AND
DATE(20140105);
Alternative to Array.from
is to use Array.prototype.forEach.call
forEach:
Array.prototype.forEach.call(htmlCollection, i => { console.log(i) });
map: Array.prototype.map.call(htmlCollection, i => { console.log(i) });
ect...
You can copy subscribers dictionary object to a same type of temporary dictionary object and then iterate the temporary dictionary object using foreach loop.
You might need to activate adb root from the developer settings menu.
If you run adb root
from the cmd line you can get:
root access is disabled by system setting - enable in settings -> development options
Once you activate the root option (ADB only or Apps and ADB) adb will restart and you will be able to use root from the cmd line.
you must add 1 day to the end date, using: DATE_ADD('$end_date', INTERVAL 1 DAY)
In 2017, the solution is:
map.addListener('click', function(e) {
placeMarker(e.latLng, map);
});
function placeMarker(position, map) {
var marker = new google.maps.Marker({
position: position,
map: map
});
map.panTo(position);
}
DC is your domain. If you want to connect to the domain example.com than your dc's are: DC=example,DC=com
You actually don't need any hostname or ip address of your domain controller (There could be plenty of them).
Just imagine that you're connecting to the domain itself. So for connecting to the domain example.com you can simply write
DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
And you're done.
You can also specify a user and a password used to connect:
DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com", "username", "password");
Also be sure to always write LDAP in upper case. I had some trouble and strange exceptions until I read somewhere that I should try to write it in upper case and that solved my problems.
The directoryEntry.Path
Property allows you to dive deeper into your domain. So if you want to search a user in a specific OU (Organizational Unit) you can set it there.
DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
directoryEntry.Path = "LDAP://OU=Specific Users,OU=All Users,OU=Users,DC=example,DC=com";
This would match the following AD hierarchy:
Simply write the hierarchy from deepest to highest.
Now you can do plenty of things
For example search a user by account name and get the user's surname:
DirectoryEntry directoryEntry = new DirectoryEntry("LDAP://example.com");
DirectorySearcher searcher = new DirectorySearcher(directoryEntry) {
PageSize = int.MaxValue,
Filter = "(&(objectCategory=person)(objectClass=user)(sAMAccountName=AnAccountName))"
};
searcher.PropertiesToLoad.Add("sn");
var result = searcher.FindOne();
if (result == null) {
return; // Or whatever you need to do in this case
}
string surname;
if (result.Properties.Contains("sn")) {
surname = result.Properties["sn"][0].ToString();
}
The easiest way to do it, at least for me:
git fetch origin <branchName> # Will fetch the branch locally
git checkout <branchName> # To move to that branch
First install "Microsoft ASP.NET Web API Client" nuget package:
PM > Install-Package Microsoft.AspNet.WebApi.Client
Then use the following function to post your data:
public static async Task<TResult> PostFormUrlEncoded<TResult>(string url, IEnumerable<KeyValuePair<string, string>> postData)
{
using (var httpClient = new HttpClient())
{
using (var content = new FormUrlEncodedContent(postData))
{
content.Headers.Clear();
content.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
HttpResponseMessage response = await httpClient.PostAsync(url, content);
return await response.Content.ReadAsAsync<TResult>();
}
}
}
And this is how to use it:
TokenResponse tokenResponse =
await PostFormUrlEncoded<TokenResponse>(OAuth2Url, OAuth2PostData);
or
TokenResponse tokenResponse =
(Task.Run(async ()
=> await PostFormUrlEncoded<TokenResponse>(OAuth2Url, OAuth2PostData)))
.Result
or (not recommended)
TokenResponse tokenResponse =
PostFormUrlEncoded<TokenResponse>(OAuth2Url, OAuth2PostData).Result;
I founded the problem:
Just insert the folder without the executable file.
so Instead of:
C:\Program Files (x86)\SumatraPDF\SumatraPDF.exe
you have to write this:
C:\Program Files (x86)\SumatraPDF\
I found this question after after making a merge and forgetting to checkout develop immediately afterwards. You guessed it: I started modifying a few files directly on master. D'Oh! As my situation is hardly unique (we've all done it, haven't we ;->), I'll offer a reversible way I used to discard all changes to get master looking like develop again.
After doing a git diff
to see what files were modified and assess the scope of my error, I executed:
git stash
git stash clear
After first stashing all the changes, they were next cleared. All the changes made to the files in error to master were gone and parity restored.
Let's say I now wanted to restore those changes. I can do this. First step is to find the hash of the stash I just cleared/dropped:
git fsck --no-reflog | awk '/dangling commit/ {print $3}'
After learning the hash, I successfully restored the uncommitted changes with:
git stash apply hash-of-cleared-stash
I didn't really want to restore those changes, just wanted to validate I could get them back, so I cleared them again.
Another option is to apply the stash to a different branch, rather than wipe the changes. So in terms of clearing changes made from working on the wrong branch, stash
gives you a lot of flexibility to recover from your boo-boo.
Anyhoo, if you want a reversible means of clearing changes to a branch, the foregoing is a less dangerous way in this use-case.
Try this regex:
^(\+?\d{1,4}[\s-])?(?!0+\s+,?$)\d{10}\s*,?$
Explanation of the regex using Perl's YAPE is as below:

\+? '+' (optional (matching the most amount
possible))
----------------------------------------------------------------------
\d{1,4} digits (0-9) (between 1 and 4 times

----------------------------------------------------------------------
[\s-] any character of: whitespace (\n, \r,
\t, \f, and " "), '-'
----------------------------------------------------------------------
)? end of \1 (NOTE: because you are using a

The following command will work for you, if you want to change default path. Just type this in bin directory of mongodb.
mongod --dbpath=yourdirectory\data\db
In case you want to move existing data too, then just copy all the folders from existing data\db directory to new directory before you execute the command.
And also stop existing mongodb services which are running.
In sql developer define properties by default "ON". If it is "OFF" any case, use below steps.
set define on;
define batchNo='123';
update TABLE_NAME SET IND1 = 'Y', IND2 = 'Y' WHERE BATCH_NO = '&batchNo';
I googled this problem for quite a while, then it occurred to me that there is an Android method, android.text.util.Linkify, that utilizes some pretty robust regexes to accomplish this. Luckily, Android is open source.
They use a few different patterns for matching different types of urls. You can find them all here: http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/2.0_r1/android/text/util/Regex.java#Regex.0WEB_URL_PATTERN
If you're just concerned about url's that match the WEB_URL_PATTERN, that is, urls that conform to the RFC 1738 spec, you can use this:

If you want to be really fancy, you can test for email addresses as well. The regex for email addresses is:
/[a-zA-Z0-9\\+\\.\\_\\%\\-]{1,256}\\@[a-zA-Z0-9][a-zA-Z0-9\\-]{0,64}(\\.[a-zA-Z0-9][a-zA-Z0-9\\-]{0,25})+/gi
PS: The top level domains supported by above regex are current as of June 2007. For an up to date list you'll need to check https://data.iana.org/TLD/tlds-alpha-by-domain.txt.

Most of the solutions given here to create the prepared query are more complex that they need to be. Using PHP's built in functions you can easily creare the SQL statement without significant overhead.
Given $records
, an array of records where each record is itself an indexed array (in the form of field => value
), the following function will insert the records into the given table $table
, on a PDO connection $connection
, using only a single prepared statement. Note that this is a PHP 5.6+ solution because of the use of argument unpacking in the call to array_push
:
private function import(PDO $connection, $table, array $records)
{
$fields = array_keys($records[0]);
$placeHolders = substr(str_repeat(',?', count($fields)), 1);
$values = [];
foreach ($records as $record) {
array_push($values, ...array_values($record));
}
$query = 'INSERT INTO ' . $table . ' (';
$query .= implode(',', $fields);
$query .= ') VALUES (';
$query .= implode('),(', array_fill(0, count($records), $placeHolders));
$query .= ')';
$statement = $connection->prepare($query);
$statement->execute($values);
}

You need a gutter between two div gutter can be made as following
margin(gutter) = width - gutter size E.g margin = calc(70% - 2em)
<body bgcolor="gray">
<section id="main">
<div id="left">
Something here
</div>
<div id="right">
Someone there
</div>
</section>
</body>
<style>
body{
font-size: 10px;

#main div{
float: left;
background-color:#ffffff;
width: calc(50% - 1.5em);
margin-left: 1.5em;
}
</style>
This will select and deselect all checkboxes:
function checkAll()
{
var checkboxes = document.getElementsByTagName('input'), val = null;
for (var i = 0; i < checkboxes.length; i++)
{
if (checkboxes[i].type == 'checkbox')
{
if (val === null) val = checkboxes[i].checked;
checkboxes[i].checked = val;
}
}
}
You can use querySelectAll directly on the table to get the list of checkboxes instead of searching the whole document, but It might not be compatible with old browsers so you need to check that first:
function checkAll()
{
var table = document.getElementById ('dataTable');
var checkboxes = table.querySelectorAll ('input[type=checkbox]');
var val = checkboxes[0].checked;
for (var i = 0; i < checkboxes.length; i++) checkboxes[i].checked = val;
}
Or to be more specific for the provided html structure in the OP question, this would be more efficient when selecting the checkboxes as it will access them directly instead of searching for them:
function checkAll (tableID)
{
var table = document.getElementById (tableID);
var val = table.rows[0].cells[0].children[0].checked;
for (var i = 1; i < table.rows.length; i++)
{
table.rows[i].cells[0].children[0].checked = val;
}
}
I have faced such problems when the class is in the default folder, i.e. when the class does not declare a package.
So I guess using a package statement (eg. package org.me.mypackage;
) on top of the class should fix it.
Sharer.php no longer allows you to customize. The page you share will be scraped for OG Tags and that data will be shared.
To properly customize, use FB.UI

To change which upstream remote is "wired" to your branch, use the git branch
command with the upstream configuration flag.
Ensure the remote exists first:
git remote -vv
Set the preferred remote for the current (checked out) branch:
git branch --set-upstream-to <remote-name>
Validate the branch is setup with the correct upstream remote:
git branch -vv
You must handle ArrayIndexOutOfBounds by yourself when adding to a certain position.
For convenience, you may use this extension function in Kotlin
/**

*/
fun <T> MutableList<T>.insert(index: Int, element: T) {
if (index <= size) {
add(index, element)
} else {
add(element)
}
}
As others have answered, the mysqli API can execute multi-queries with the msyqli_multi_query() function.
For what it's worth, PDO supports multi-query by default, and you can iterate over the multiple result sets of your multiple queries:
$stmt = $dbh->prepare("
select sql_calc_found_rows * from foo limit 1 ;
select found_rows()");
$stmt->execute();
do {
while ($row = $stmt->fetch()) {
print_r($row);
}
} while ($stmt->nextRowset());
However, multi-query is pretty widely considered a bad idea for security reasons. If you aren't careful about how you construct your query strings, you can actually get the exact type of SQL injection vulnerability shown in the classic "Little Bobby Tables" XKCD cartoon. When using an API that restrict you to single-query, that can't happen.
uint8
, uint16
, uint32
, and uint64
are probably Microsoft-specific types.
As of the 1999 standard, C supports standard typedefs with similar meanings, defined in <stdint.h>
: uint8_t
, uint16_t
, uint32_t
, and uint64_t
. I'll assume that the Microsoft-specific types are defined similarly. Microsoft does support <stdint.h>
, at least as of Visual Studio 2010, but older code may use uint8
et al.
The predefined types char
, short
, int
et al have sizes that vary from one C implementation to another. The C standard has certain minimum requirements (char
is at least 8 bits, short
and int
are at least 16, long
is at least 32, and each type in that list is at least as wide as the previous type), but permits some flexibility. For example, I've seen systems where int
is 16, 32, or 64 bits.
char
is almost always exactly 8 bits, but it's permitted to be wider. And plain char
may be either signed or unsigned.
uint8_t
is required to be an unsigned integer type that's exactly 8 bits wide. It's likely to be a typedef for unsigned char
, though it might be a typedef for plain char
if plain char
happens to be unsigned. If there is no predefined 8-bit unsigned type, then uint8_t
will not be defined at all.
Similarly, each uintN_t
type is an unsigned type that's exactly N bits wide.
In addition, <stdint.h>
defines corresponding signed intN_t
types, as well as int_fastN_t
and int_leastN_t
types that are at least the specified width.
The [u]intN_t
types are guaranteed to have no padding bits, so the size of each is exactly N bits. The signed intN_t
types are required to use a 2's-complement representation.
Although uint32_t
might be the same as unsigned int
, for example, you shouldn't assume that. Use unsigned int
when you need an unsigned integer type that's at least 16 bits wide, and that's the "natural" size for the current system. Use uint32_t
when you need an unsigned integer type that's exactly 32 bits wide.
(And no, uint64
or uint64_t
is not the same as double
; double
is a floating-point type.)
You have to place the hello

In addition to verifying that the executables are in your path, you should also make sure that Ant can find tools.jar

to the Ant classpath:
The Snack Sound Toolkit can play wav, au and mp3 files.

Only one thing needs to be done to solve the problem: upgrade TeamCity to version 8.1.x or higher because support for Visual Studio 2012/2013 and MSBuild Tools 2013 was only introduced in TeamCity 8.1. Once you've upgraded your TeamCity modify MSBuild Tools Version setting in your build step accordingly ans the problem will disappear. For more info read here: http://blog.turlov.com/2014/07/upgrade-teamcity-to-enable-support-for.html
I found working with the {% with %}
tag to be quite a hassle. Instead I created the following template tag, which should work on strings and integers.
from django import template
register = template.Library()
@register.filter
def concat_string(value_1, value_2):
return str(value_1) + str(value_2)
Then load the template tag in your template at the top using the following:
{% load concat_string %}
You can then use it the following way:
<a href="{{ SOME_DETAIL_URL|concat_string:object.pk }}" target="_blank">123</a>
I personally found this to be a lot cleaner to work with.
Although returning a pointer to a local object is bad practice, it didn't cause the kaboom here. Here's why you got a segfault:
int *fun()
{
int *point;
*point=12; <<<<<< your program crashed here.
return point;
}
The local pointer goes out of scope, but the real issue is dereferencing a pointer that was never initialized. What is the value of point? Who knows. If the value did not map to a valid memory location, you will get a SEGFAULT. If by luck it mapped to something valid, then you just corrupted memory by overwriting that place with your assignment to 12.
Since the pointer returned was immediately used, in this case you could get away with returning a local pointer. However, it is bad practice because if that pointer was reused after another function call reused that memory in the stack, the behavior of the program would be undefined.
int *fun()
{
int point;
point = 12;
return (&point);
}
or almost identically:
int *fun()
{
int point;
int *point_ptr;
point_ptr = &point;
*point_ptr = 12;
return (point_ptr);
}
Another bad practice but safer method would be to declare the integer value as a static variable, and it would then not be on the stack and would be safe from being used by another function:
int *fun()
{
static int point;
int *point_ptr;
point_ptr = &point;
*point_ptr = 12;
return (point_ptr);
}
or
int *fun()
{
static int point;
point = 12;
return (&point);
}
As others have mentioned, the "right" way to do this would be to allocate memory on the heap, via malloc.
Strictly stated you must check all of the following: defined, not empty AND not None.
For "normal" variables it makes a difference if defined and set or not set. See foo
and bar
in the example below. Both are defined but only foo
is set.
On the other side registered variables are set to the result of the running command and vary from module to module. They are mostly json structures. You probably must check the subelement you're interested in. See xyz
and xyz.msg
in the example below:
cat > test.yml <<EOF
- hosts: 127.0.0.1
vars:
foo: "" # foo is defined and foo == '' and foo != None
bar: # bar is defined and bar != '' and bar == None
tasks:
- debug:
msg : ""
register: xyz # xyz is defined and xyz != '' and xyz != None
# xyz.msg is defined and xyz.msg == '' and xyz.msg != None
- debug:
msg: "foo is defined and foo == '' and foo != None"
when: foo is defined and foo == '' and foo != None
- debug:
msg: "bar is defined and bar != '' and bar == None"
when: bar is defined and bar != '' and bar == None
- debug:
msg: "xyz is defined and xyz != '' and xyz != None"
when: xyz is defined and xyz != '' and xyz != None
- debug:
msg: "{{ xyz }}"
- debug:
msg: "xyz.msg is defined and xyz.msg == '' and xyz.msg != None"
when: xyz.msg is defined and xyz.msg == '' and xyz.msg != None
- debug:
msg: "{{ xyz.msg }}"

In Python 3, they made the /
operator do a floating-point division, and added the //
operator to do integer division (i.e., quotient without remainder); whereas in Python 2, the /
operator was simply integer division, unless one of the operands was already a floating point number.
In Python 2.X:
>>> 10/3
3
>>> # To get a floating point number from integer division:
>>> 10.0/3
3.3333333333333335
>>> float(10)/3

Those two parameters (or variants of) are sent, by convention, with all events.
sender
: The object which has raised the evente
an instance of EventArgs
including, in many cases, an object which inherits from EventArgs
. Contains additional information about the event, and sometimes provides ability for code handling the event to alter the event somehow.In the case of the events you mentioned, neither parameter is particularly useful. The is only ever one page raising the events, and the EventArgs
are Empty
as there is no further information about the event.
Looking at the 2 parameters separately, here are some examples where they are useful.
sender
Say you have multiple buttons on a form. These buttons could contain a Tag
describing what clicking them should do. You could handle all the Click
events with the same handler, and depending on the sender
do something different
private void HandleButtonClick(object sender, EventArgs e)
{
Button btn = (Button)sender;
if(btn.Tag == "Hello")
MessageBox.Show("Hello")
else if(btn.Tag == "Goodbye")
Application.Exit();
// etc.
}
Disclaimer : That's a contrived example; don't do that!
e
Some events are cancelable. They send CancelEventArgs
instead of EventArgs
. This object adds a simple boolean property Cancel
on the event args. Code handling this event can cancel the event:
private void HandleCancellableEvent(object sender, CancelEventArgs e)
{
if(/* some condition*/)
{
// Cancel this event
e.Cancel = true;
}
}
You cannot cast List<TestB>
to List<TestA>
as Steve Kuo mentions BUT you can dump the contents of List<TestA>
into List<TestB>
. Try the following:
List<TestA> result = new List<TestA>();
List<TestB> data = new List<TestB>();
result.addAll(data);
I've not tried this code so there are probably mistakes but the idea is that it should iterate through the data object adding the elements (TestB objects) into the List. I hope that works for you.
If you want to do it in the adapter, you can simply do this:
itemView.setOnLongClickListener(new View.OnLongClickListener()
{
@Override
public boolean onLongClick(View v) {
Toast.makeText(mContext, "Long pressed on item", Toast.LENGTH_SHORT).show();
}
});
in AndroidManifest.xml set theme holo like this:
<activity
android:name="your Fragment or activity"
android:label="@string/xxxxxx"
android:theme="@android:style/Theme.Holo" >
Acoording to RFC 2046 (Multipurpose Internet Mail Extensions):
The recommended action for an implementation that receives an
"application/octet-stream" entity is to simply offer to put the data in a file
So I'd go for that one.
You could use a simple array intersection, this way you can know what differs in each hash.
hash1 = { a: 1 , b: 2 }
hash2 = { a: 2 , b: 2 }
overlapping_elements = hash1.to_a & hash2.to_a
exclusive_elements_from_hash1 = hash1.to_a - overlapping_elements
exclusive_elements_from_hash2 = hash2.to_a - overlapping_elements
String search = "A";
for(String s : myList)
if(s.contains(search)) return true;
return false;
This will iterate over each string in the list, and check if it contains the string you're looking for. If it's only spaces you want to trap for, you can do this:
String search = "A";
for(String s : myList)
if(s.replaceAll(" ","").contains(search)) return true;
return false;
which will first replace spaces with empty strings before searching. Additionally, if you just want to trim the string first, you can do:
String search = "A";
for(String s : myList)
if(s.trim().contains(search)) return true;
return false;
After RC2 and 1.0 you no longer need to inject an IHttpContextAccessor
to you extension class. It is immediately available in the IUrlHelper
through the urlhelper.ActionContext.HttpContext.Request
. You would then create an extension class following the same idea, but simpler since there will be no injection involved.
public static string AbsoluteAction(
this IUrlHelper url,
string actionName,
string controllerName,
object routeValues = null)
{
string scheme = url.ActionContext.HttpContext.Request.Scheme;
return url.Action(actionName, controllerName, routeValues, scheme);
}
Leaving the details on how to build it injecting the accesor in case they are useful to someone. You might also just be interested in the absolute url of the current request, in which case take a look at the end of the answer.
You could modify your extension class to use the IHttpContextAccessor
interface to get the HttpContext
. Once you have the context, then you can get the HttpRequest
instance from HttpContext.Request
and use its properties Scheme
, Host
, Protocol
etc as in:
string scheme = HttpContextAccessor.HttpContext.Request.Scheme;
For example, you could require your class to be configured with an HttpContextAccessor:
public static class UrlHelperExtensions
{
private static IHttpContextAccessor HttpContextAccessor;
public static void Configure(IHttpContextAccessor httpContextAccessor)
{
HttpContextAccessor = httpContextAccessor;
}
public static string AbsoluteAction(
this IUrlHelper url,
string actionName,
string controllerName,
object routeValues = null)
{
string scheme = HttpContextAccessor.HttpContext.Request.Scheme;
return url.Action(actionName, controllerName, routeValues, scheme);
}
....
}
Which is something you can do on your Startup
class (Startup.cs file):
public void Configure(IApplicationBuilder app)
{
...
var httpContextAccessor = app.ApplicationServices.GetRequiredService<IHttpContextAccessor>();
UrlHelperExtensions.Configure(httpContextAccessor);
...
}
You could probably come up with different ways of getting the IHttpContextAccessor
in your extension class, but if you want to keep your methods as extension methods in the end you will need to inject the IHttpContextAccessor
into your static class. (Otherwise you will need the IHttpContext
as an argument on each call)
Just getting the absoluteUri of the current request
If you just want to get the absolute uri of the current request, you can use the extension methods GetDisplayUrl
or GetEncodedUrl
from the UriHelper
class. (Which is different from the UrLHelper)
GetDisplayUrl. Returns the combined components of the request URL in a fully un-escaped form (except for the QueryString) suitable only for display. This format should not be used in HTTP headers or other HTTP operations.
GetEncodedUrl. Returns the combined components of the request URL in a fully escaped form suitable for use in HTTP headers and other HTTP operations.
In order to use them:
Microsoft.AspNet.Http.Extensions
. HttpContext
instance. It is already available in some classes (like razor views), but in others you might need to inject an IHttpContextAccessor
as explained above. this.Context.Request.GetDisplayUrl()
An alternative to those methods would be manually crafting yourself the absolute uri using the values in the HttpContext.Request
object (Similar to what the RequireHttpsAttribute does):
var absoluteUri = string.Concat(
request.Scheme,
"://",
request.Host.ToUriComponent(),
request.PathBase.ToUriComponent(),
request.Path.ToUriComponent(),
request.QueryString.ToUriComponent());
I am not sure I got you but this might be what you are looking for:
SELECT i.invoiceid, sum(case when i.amount is not null then i.amount else 0 end), sum(case when i.amount is not null then i.amount else 0 end) - sum(case when p.amount is not null then p.amount else 0 end) AS amountdue
FROM invoices i
LEFT JOIN invoicepayments ip ON i.invoiceid = ip.invoiceid
LEFT JOIN payments p ON ip.paymentid = p.paymentid
LEFT JOIN customers c ON p.customerid = c.customerid
WHERE c.customernumber = '100'
GROUP BY i.invoiceid
This would get you the amounts sums in case there are multiple payment rows for each invoice
The Instagram API is meant for not only you, but for any Instagram user to potentially authenticate with your app. I followed the instructions on the Instagram Dev website. Using the first (Explicit) method, I was able to do this quite easily on the server.
Step 1) Add a link or button to your webpage which a user could click to initiate the authentication process:
<a href="https://api.instagram.com/oauth/authorize/?client_id=YOUR_CLIENT_ID&redirect_uri=YOUR_REDIRECT_URI&response_type=code">Get Started</a>
YOUR_CLIENT_ID
and YOUR_REDIRECT_URI
will be given to you after you successfully register your app in the Instagram backend, along with YOUR_CLIENT_SECRET
used below.
Step 2) At the URI that you defined for your app, which is the same as YOUR_REDIRECT_URI
, you need to accept the response from the Instagram server. The Instagram server will feed you back a code
variable in the request. Then you need to use this code
and other information about your app to make another request directly from your server to obtain the access_token
. I did this in python using Django framework, as follows:
direct django to the response
function in urls.py
:
from django.conf.urls import url
from . import views
app_name = 'main'
urlpatterns = [
url(r'^$', views.index, name='index'),
url(r'^response/', views.response, name='response'),
]
Here is the response
function, handling the request, views.py
:
from django.shortcuts import render
import urllib
import urllib2
import json
def response(request):
if 'code' in request.GET:
url = 'https://api.instagram.com/oauth/access_token'
values = {
'client_id':'YOUR_CLIENT_ID',
'client_secret':'YOUR_CLIENT_SECRET',
'redirect_uri':'YOUR_REDIRECT_URI',
'code':request.GET.get('code'),
'grant_type':'authorization_code'
}
data = urllib.urlencode(values)
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
response_string = response.read()
insta_data = json.loads(response_string)
if 'access_token' in insta_data and 'user' in insta_data:
#authentication success
return render(request, 'main/response.html')
else:
#authentication failure after step 2
return render(request, 'main/auth_error.html')
elif 'error' in req.GET:
#authentication failure after step 1
return render(request, 'main/auth_error.html')
This is just one way, but the process should be almost identical in PHP or any other server-side language.
You can use SingleOrDefault
to get a single object matching your criteria, and then pass that to the Remove
method of your EF table.
var itemToRemove = Context.Employ.SingleOrDefault(x => x.id == 1); //returns a single item.
if (itemToRemove != null) {
Context.Employ.Remove(itemToRemove);
Context.SaveChanges();
}
You don't. The closest thing you can do is working with Maps to simulate it, or defining your own Objects to deal with.
If you want to add the absent serialVersionUID for a bunch of files, IntelliJ IDEA may not work very well. I come up some simple script to fulfill this goal with ease:
base_dir=$(pwd)
src_dir=$base_dir/src/main/java
ic_api_cp=$base_dir/target/classes
while read f
do
clazz=${f//\//.}
clazz=${clazz/%.java/}
seruidstr=$(serialver -classpath $ic_api_cp $clazz | cut -d ':' -f 2 | sed -e 's/^\s\+//')
perl -ni.bak -e "print $_; printf qq{%s\n}, q{ private $seruidstr} if /public class/" $src_dir/$f
done
You save this script, say as add_serialVersionUID.sh
in your ~/bin
folder. Then you run it in the root directory of your Maven or Gradle project like:
add_serialVersionUID.sh < myJavaToAmend.lst
This .lst includes the list of Java files to add the serialVersionUID in the following format:
com/abc/ic/api/model/domain/item/BizOrderTransDO.java

Just consider how the SWITCH might work,
This is a very bothersome question, and I feel contributes to many being opposed to Java despite how useful of a language it is.
The fact that you can't trust "System.gc" to do anything is incredibly daunting and can easily invoke "Fear, Uncertainty, Doubt" feel to the language.
In many cases, it is nice to deal with memory spikes that you cause on purpose before an important event occurs, which would cause users to think your program is badly designed/unresponsive.
Having ability to control the garbage collection would be very a great education tool, in turn improving people's understanding how the garbage collection works and how to make programs exploit it's default behavior as well as controlled behavior.
Let me review the arguments of this thread.
Often, the program may not be doing anything and you know it's not doing anything because of the way it was designed. For instance, it might be doing some kind of long wait with a large wait message box, and at the end it may as well add a call to collect garbage because the time to run it will take a really small fraction of the time of the long wait but will avoid gc from acting up in the middle of a more important operation.
I disagree, it doesn't matter what garbage collector you have. Its' job is to track garbage and clean it.
By calling the gc during times where usage is less critical, you reduce odds of it running when your life relies on the specific code being run but instead it decides to collect garbage.
Sure, it might not behave the way you want or expect, but when you do want to call it, you know nothing is happening, and user is willing to tolerate slowness/downtime. If the System.gc works, great! If it doesn't, at least you tried. There's simply no down side unless the garbage collector has inherent side effects that do something horribly unexpected to how a garbage collector is suppose to behave if invoked manually, and this by itself causes distrust.
It is a use case that cannot be achieved reliably, but could be if the system was designed that way. It's like making a traffic light and making it so that some/all of the traffic lights' buttons don't do anything, it makes you question why the button is there to begin with, javascript doesn't have garbage collection function so we don't scrutinize it as much for it.
what is a "hint"? what is "ignore"? a computer cannot simply take hints or ignore something, there are strict behavior paths it takes that may be dynamic that are guided by the intent of the system. A proper answer would include what the garbage collector is actually doing, at implementation level, that causes it to not perform collection when you request it. Is the feature simply a nop? Is there some kind of conditions that must me met? What are these conditions?
As it stands, Java's GC often seems like a monster that you just don't trust. You don't know when it's going to come or go, you don't know what it's going to do, how it's going to do it. I can imagine some experts having better idea of how their Garbage Collection works on per-instruction basis, but vast majority simply hopes it "just works", and having to trust an opaque-seeming algorithm to do work for you is frustrating.
There is a big gap between reading about something or being taught something, and actually seeing the implementation of it, the differences across systems, and being able to play with it without having to look at the source code. This creates confidence and feeling of mastery/understanding/control.
To summarize, there is an inherent problem with the answers "this feature might not do anything, and I won't go into details how to tell when it does do something and when it doesn't and why it won't or will, often implying that it is simply against the philosophy to try to do it, even if the intent behind it is reasonable".
It might be okay for Java GC to behave the way it does, or it might not, but to understand it, it is difficult to truly follow in which direction to go to get a comprehensive overview of what you can trust the GC to do and not to do, so it's too easy simply distrust the language, because the purpose of a language is to have controlled behavior up to philosophical extent(it's easy for a programmer, especially novices to fall into existential crisis from certain system/language behaviors) you are capable of tolerating(and if you can't, you just won't use the language until you have to), and more things you can't control for no known reason why you can't control them is inherently harmful.
Try this if you unbind the onclick event by ID Then use:
$('#youLinkID').attr('onclick','').unbind('click');
Try this if you unbind the onclick event by Class Then use:
$('.className').attr('onclick','').unbind('click');
That's the error you get when a function makes too many recursive calls to itself. It might be doing this because the base case is never met (and therefore it gets stuck in an infinite loop) or just by making an large number of calls to itself. You could replace the recursive calls with while loops.
Recently, I have tried to develop a simple web app that uses drag and drop components and has lines connecting them. I came across these two simple and amazing javascript libraries:
Working example link (usage: click on add scene to create a draggable, click on add choice to draw a leader line between two different draggables)
Justin(above) is accurate. However, keep in mind that depending on who you get the certificate from (intermediate CA, root CA involved or not) or how the pfx is created/exported, sometimes they could be missing the certificate chain. After Import, You would have a certificate of PrivateKeyEntry type, but with a chain of length of 1.
To fix this, there are several options. The easier option in my mind is to import and export the pfx file in IE(choosing the option of Including all the certificates in the chain). The import and export process of certificates in IE should be very easy and well documented elsewhere.
Once exported, import the keystore as Justin pointed above. Now, you would have a keystore with certificate of type PrivateKeyEntry and with a certificate chain length of more than 1.
Certain .Net based Web service clients error out(unable to establish trust relationship), if you don't do the above.
You can also pass in '0' as the value for the column to auto-increment, the correct value will be used when the record is created. This is so much easier than temporary tables.

In my case the issue was caused by forgetting to call next()
in an expressjs `use' method call.
If the current middleware does not end the request-response cycle, it must call next() to pass control to the next middleware, otherwise the request will be left hanging.
unique_ptr
's like that.I believe you're making a terrible mess - for those who will need to read your code, maintain it, and probably those who need to use it.
unique_ptr
constructor parameters if you have publicly-exposed unique_ptr
members.unique_ptr
s wrap raw pointers for ownership & lifetime management. They're great for localized use - not good, nor in fact intended, for interfacing. Wanna interface? Document your new class as ownership-taking, and let it get the raw resource; or perhaps, in the case of pointers, use owner<T*>
as suggested in the Core Guidelines.
Only if the purpose of your class is to hold unique_ptr
's, and have others use those unique_ptr
's as such - only then is it reasonable for your constructor or methods to take them.
unique_ptr
s internallyUsing unique_ptr
for list nodes is very much an implementation detail. Actually, even the fact that you're letting users of your list-like mechanism just use the bare list node directly - constructing it themselves and giving it to you - is not a good idea IMHO. I should not need to form a new list-node-which-is-also-a-list to add something to your list - I should just pass the payload - by value, by const lvalue ref and/or by rvalue ref. Then you deal with it. And for splicing lists - again, value, const lvalue and/or rvalue.
color:transparent;
and then any text-transform
property does the trick too.
For example:
color: transparent;
text-transform: uppercase;
It is reasonable to expect that you cannot do any better than O(N log N) in running time.
However, the interesting part is to investigate whether you can sort it in-place, stably, its worst-case behavior and so on.
Simon Tatham, of Putty fame, explains how to sort a linked list with merge sort. He concludes with the following comments:
Like any self-respecting sort algorithm, this has running time O(N log N). Because this is Mergesort, the worst-case running time is still O(N log N); there are no pathological cases.
Auxiliary storage requirement is small and constant (i.e. a few variables within the sorting routine). Thanks to the inherently different behaviour of linked lists from arrays, this Mergesort implementation avoids the O(N) auxiliary storage cost normally associated with the algorithm.
There is also an example implementation in C that work for both singly and doubly linked lists.
As @Jørgen Fogh mentions below, big-O notation may hide some constant factors that can cause one algorithm to perform better because of memory locality, because of a low number of items, etc.
For me I had to put the whole interval in single quotes not just the value of the interval.
select id,
title,
created_at + interval '1 day' * claim_window as deadline from projects
Instead of
select id,
title,
created_at + interval '1' day * claim_window as deadline from projects
$uri_parts = explode('?', $_SERVER['REQUEST_URI'], 2);
$request_uri = $uri_parts[0];
echo $request_uri;
I was receiving the same error. You need to go increase the column length while importing the data for particular column. Choose a data source >> Advanced >> increase the column from default 50 to 200 or more.
It worked for me!
cdecl
is a great tool for deciphering weird syntax like function pointer declarations. You can use it to generate them as well.
As far as tips for making complicated declarations easier to parse for future maintenance (by yourself or others), I recommend making typedef
s of small chunks and using those small pieces as building blocks for larger and more complicated expressions. For example:
typedef int (*FUNC_TYPE_1)(void);
typedef double (*FUNC_TYPE_2)(void);
typedef FUNC_TYPE_1 (*FUNC_TYPE_3)(FUNC_TYPE_2);
rather than:
typedef int (*(*FUNC_TYPE_3)(double (*)(void)))(void);
cdecl
can help you out with this stuff:
cdecl> explain int (*FUNC_TYPE_1)(void)
declare FUNC_TYPE_1 as pointer to function (void) returning int
cdecl> explain double (*FUNC_TYPE_2)(void)
declare FUNC_TYPE_2 as pointer to function (void) returning double
cdecl> declare FUNC_TYPE_3 as pointer to function (pointer to function (void) returning double) returning pointer to function (void) returning int
int (*(*FUNC_TYPE_3)(double (*)(void )))(void )
And is (in fact) exactly how I generated that crazy mess above.
Ruby can't find any root certificates to trust.
Take a look at this blog post for a solution: "Ruby 1.9 and the SSL error".
The solution is to install the
curl-ca-bundle
port which contains the same root certificates used by Firefox:sudo port install curl-ca-bundle
and tell your
https
object to use it:https.ca_file = '/opt/local/share/curl/curl-ca-bundle.crt'
Note that if you want your code to run on Ubuntu, you need to set the
ca_path
attribute instead, with the default certificates location/etc/ssl/certs
.
var value1=$("id1").val();
var value2=$("id2").val();
data:"{'data1':'"+value1+"','data2':'"+value2+"'}"
You can use this way to pass data
There's literature about it:
Optimized Pagination using MySQL, making the difference between counting the total amount of rows, and pagination.

The main problem happens with the usage of large OFFSET
s. They avoid using OFFSET
with a variety of techniques, ranging from id
range selections in the WHERE
clause, to some kind of caching or pre-computing pages.

First of all you need to remove the data-toggle attribute. We will use some JQuery, so make sure you include it.
<ul class='nav nav-tabs'>
<li class='active'><a href='#home'>Home</a></li>
<li><a href='#menu1'>Menu 1</a></li>
<li><a href='#menu2'>Menu 2</a></li>
<li><a href='#menu3'>Menu 3</a></li>
</ul>
<div class='tab-content'>
<div id='home' class='tab-pane fade in active'>
<h3>HOME</h3>
<div id='menu1' class='tab-pane fade'>
<h3>Menu 1</h3>
</div>
<div id='menu2' class='tab-pane fade'>
<h3>Menu 2</h3>
</div>
<div id='menu3' class='tab-pane fade'>
<h3>Menu 3</h3>
</div>
</div>
</div>
<script>
$(document).ready(function(){
// Handling data-toggle manually
$('.nav-tabs a').click(function(){
$(this).tab('show');
});
// The on tab shown event
$('.nav-tabs a').on('shown.bs.tab', function (e) {
alert('Hello from the other siiiiiide!');
var current_tab = e.target;
var previous_tab = e.relatedTarget;
});
});
</script>
You can easily call a method from any Fragment inside your Activity by doing a cast like this:
Java
((MainActivity)getActivity()).startChronometer();
Kotlin
(activity as MainActivity).startChronometer()
Just remember to make sure this Fragment's activity is in fact MainActivity before you do it.
Hope this helps!
final
means that the value cannot be changed after initialization, that's what makes it a constant. static
means that instead of having space allocated for the field in each object, only one instance is created for the class.
So, static final
means only one instance of the variable no matter how many objects are created and the value of that variable can never change.

It's worth keeping in mind that PowerShell 3 on Windows 7 does not have all the cmdlets as PowerShell 3 on Windows 8. So you may still encounter cmdlets that are not present on your system.
