This worked for me, the key is you need a separate thread to analyze the socket state with polling. doing it in the same thread as the socket fails detection.
//open or receive a server socket - TODO your code here
socket = new Socket(....);
//enable the keep alive so we can detect closure
socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.KeepAlive, true);
//create a thread that checks every 5 seconds if the socket is still connected. TODO add your thread starting code
void MonitorSocketsForClosureWorker() {
DateTime nextCheckTime = DateTime.Now.AddSeconds(5);
while (!exitSystem) {
if (nextCheckTime < DateTime.Now) {
try {
if (socket!=null) {
if(socket.Poll(5000, SelectMode.SelectRead) && socket.Available == 0) {
//socket not connected, close it if it's still running
socket.Close();
socket = null;
} else {
//socket still connected
}
}
} catch {
socket.Close();
} finally {
nextCheckTime = DateTime.Now.AddSeconds(5);
}
}
Thread.Sleep(1000);
}
}

If you want to take advantage of the 60FPS smoothness that the "transform" property offers, you can combine the two:
@keyframes changewidth {
from {
transform: scaleX(1);
}
to {
transform: scaleX(2);
}
}
div {
animation-duration: 0.1s;
animation-name: changewidth;
animation-iteration-count: infinite;
animation-direction: alternate;
}
More explanation on why transform offers smoother transitions here: https://medium.com/outsystems-experts/how-to-achieve-60-fps-animations-with-css3-db7b98610108
Assigning questionFrame.frame.size.height= screenSize.height * 0.30
will not reflect anything in the view. because it is a get-only property. If you want to change the frame of questionFrame you can use the below code.
questionFrame.frame = CGRect(x: 0, y: 0, width: 0, height: screenSize.height * 0.70)
Are you using Forms authentication?
Forms authentication uses it own value for timeout (30 min. by default). A forms authentication timeout will send the user to the login page with the session still active. This may look like the behavior your app gives when session times out making it easy to confuse one with the other.
<system.web>
<authentication mode="Forms">
<forms timeout="50"/>
</authentication>
<sessionState timeout="60" />
</system.web>
Setting the forms timeout to something less than the session timeout can give the user a window in which to log back in without losing any session data.
The basic technique (on most modern systems) is to subtract the two numbers and then to check the sign bit of the result, i.e. see if the result is greater than/equal to/less than zero. In the assembly code instead of getting the result directly (into a register), you normally just branch depending on the state:
; Compare r1 and r2
CMP $r1, $r2
JLT lessthan
greater_or_equal:
; print "r1 >= r2" somehow
JMP l1
lessthan:
; print "r1 < r2" somehow

For me, the try_files
directive in the (currently most voted) answer https://stackoverflow.com/a/11957896/608359 led to rewrite cycles,
*173 rewrite or internal redirection cycle while internally redirecting
I had better luck with the index directive. Note that I used a forward slash before the name, which might or might not be what you want.
server {
listen 443 ssl;
server_name example.com;
root /home/dclo/example;
index /index.html;
error_page 404 /index.html;
# ... ssl configuration
}
In this case, I wanted all paths to lead to /index.html, including when returning a 404.
The FASTEST way, to see all parents, and IN ORDER, just use the built in __mro__
i.e. repr(YOUR_CLASS.__mro__)
>>>
>>>
>>> import getpass
>>> getpass.GetPassWarning.__mro__
outputs, IN ORDER
(<class 'getpass.GetPassWarning'>, <type 'exceptions.UserWarning'>,
<type 'exceptions.Warning'>, <type 'exceptions.Exception'>,
<type 'exceptions.BaseException'>, <type 'object'>)
>>>
There you have it. The "best" answer right now, has 182 votes (as I am typing this) but this is SO much simpler than some convoluted for loop, looking into bases one class at a time, not to mention when a class extends TWO or more parent classes. Importing and using inspect
just clouds the scope unnecessarily. It honestly is a shame people don't know to just use the built-ins
I Hope this Helps!

I had the same problem. I removed virtual device and run app on my phone - worked well. To remove virtual device: Click icon "AVD Manager" in Android Studio, select virtual device and in context menu click "Delete". Then turn on on the phone "Developer mode". Connect phone via USB to the laptop.
I am used to seeing a few basic variations on handling optional variables. Sometimes, the relaxed versions are useful.
function foo(a, b, c) {
a = a || "default"; // Matches 0, "", null, undefined, NaN, false.
a || (a = "default"); // Matches 0, "", null, undefined, NaN, false.
if (b == null) { b = "default"; } // Matches null, undefined.
if (typeof c === "undefined") { c = "default"; } // Matches undefined.
}
The falsy default used with variable a
is, for example, used extensively in Backbone.js.

Upgraded from EF5 to EF6 nuget a while back and kept encountering this issue. I'd temp fix it by updating the generated code to reference System.Data.Entity.Core.Objects
, but after generation it would be changed back again (as expected since its generated).
This solved the problem for good:
http://msdn.microsoft.com/en-us/data/upgradeef6
If you have any models created with the EF Designer, you will need to update the code generation templates to generate EF6 compatible code. Note: There are currently only EF 6.x DbContext Generator templates available for Visual Studio 2012 and 2013.
- Delete existing code-generation templates. These files will typically be named <edmx_file_name>.tt and <edmx_file_name>.Context.tt and be nested under your edmx file in Solution Explorer. You can select the templates in Solution Explorer and press the Del key to delete them.
Note: In Web Site projects the templates will not be nested under your edmx file, but listed alongside it in Solution Explorer.
Note: In VB.NET projects you will need to enable 'Show All Files' to be able to see the nested template files.- Add the appropriate EF 6.x code generation template. Open your model in the EF Designer, right-click on the design surface and select Add Code Generation Item...
- If you are using the DbContext API (recommended) then EF 6.x DbContext Generator will be available under the Data tab.
Note: If you are using Visual Studio 2012, you will need to install the EF 6 Tools to have this template. See Get Entity Framework for details.- If you are using the ObjectContext API then you will need to select the Online tab and search for EF 6.x EntityObject Generator.
- If you applied any customizations to the code generation templates you will need to re-apply them to the updated templates.
I've created a video tutorial for this. Just check:
Connect to Amazon EC2 file directory using FileZilla and SFTP, Video Tutorial
Summary of above video tutorial:
File > Site Manager Add a new site with the following parameters:
Host: Your public DNS name of your EC2 instance, or the public IP address of the server.
Protocol: SFTP
Logon Type: Normal
User: From the docs: "For Amazon Linux, the default user name is ec2-user. For RHEL5, the user name is often root but might be ec2-user. For Ubuntu, the user name is ubuntu. For SUSE Linux, the user name is root. For Debian, the user name is admin. Otherwise, check with your AMI provider."
Press Connect Button - If saving of passwords has been disabled, you will be prompted that the logon type will be changed to 'Ask for password'. Say 'OK' and when connecting, at the password prompt push 'OK' without entering a password to proceed past the dialog.
Note: FileZilla automatically figures out which key to use. You do not need to specify the key after importing it as described above.
If you use Cyberduck follow this.
Check this post if you have any permission issues.
I don't know how was the plugin the time the question was asked (2010), but I faced the same problem today and solved it this way:
Give your select tag a name attribute. For example in this case
<select name="myselect">
Instead of working with the attribute value="default" in the tag option, disable the default option or set value="" as suggested by Andrew Coats
<option disabled="disabled">Choose...</option>
or
<option value="">Choose...</option>
Set the plugin validation rule
$( "#YOUR_FORM_ID" ).validate({
rules: {
myselect: { required: true }
}
});
or
<select name="myselect" class="required">
Obs: Andrew Coats' solution works only if you have just one select in your form. If you want his solution to work with more than one select add a name attribute to your select.
Hope it helps! :)

the answers here are correct and i liked @Jyo the Whiff idea of a show and hide fragment implementation except the way he has it currently would hide the fragment on the first run so i added a slight change in that i added the isAdded check and show the fragment if its not already
public void showHideCardPreview(int id) {
FragmentManager fm = getSupportFragmentManager();
Bundle b = new Bundle();
b.putInt(Constants.CARD, id);
cardPreviewFragment.setArguments(b);
FragmentTransaction ft = fm.beginTransaction()
.setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out);
if (!cardPreviewFragment.isAdded()){
ft.add(R.id.full_screen_container, cardPreviewFragment);
ft.show(cardPreviewFragment);
} else {
if (cardPreviewFragment.isHidden()) {
Log.d(TAG,"++++++++++++++++++++ show");
ft.show(cardPreviewFragment);
} else {
Log.d(TAG,"++++++++++++++++++++ hide");
ft.hide(cardPreviewFragment);
}
}
ft.commit();
}
My solution to avoid the infinite loop was to create another state which have made the redirection:
$stateProvider.state('app.admin.main', {
url: '/admin/main',
authenticate: 'admin',
controller: ($state, $window) => {
$state.go('app.admin.overview').then(() => {
$window.location.reload();
});
}
});
I ended up using a definition list with an unordered list inside it. It solves the issue of the unwanted space above the list without needing to change every paragraph tag.
<dl><dt>Text</dt>
<dd><ul><li>First item</li>
<li>Second item</li></ul></dd></dl>
list = ["my", "name", "is", "kourosh"]
" ".join(list)
If this is an input, using the JOIN method, we can add the distance between the words and also convert the list to the string.
This is Python output
'my name is kourosh'
onmouseover="$('.play-detail').stop().animate({'height': '84px'},'300');"
onmouseout="$('.play-detail').stop().animate({'height': '44px'},'300');"
Just put two stops -- one onmouseover and one onmouseout.
Finally!
As of Java 8u191 you now have the options:
-XX:InitialRAMPercentage
-XX:MaxRAMPercentage
-XX:MinRAMPercentage
that can be used to size the heap as a percentage of the usable physical RAM. (which is same as the RAM installed less what the kernel uses).
See Release Notes for Java8 u191 for more information. Note that the options are mentioned under a Docker heading but in fact they apply whether you are in Docker environment or in a traditional environment.
The default value for MaxRAMPercentage
is 25%. This is extremely conservative.
My own rule: If your host is more or less dedicated to running the given java application, then you can without problems increase dramatically. If you are on Linux, only running standard daemons and have installed RAM from somewhere around 1 Gb and up then I wouldn't hesitate to use 75% for the JVM's heap. Again, remember that this is 75% of the RAM available, not the RAM installed. What is left is the other user land processes that may be running on the host and the other types of memory that the JVM needs (eg for stack). All together, this will typically fit nicely in the 25% that is left. Obviously, with even more installed RAM the 75% is a safer and safer bet. (I wish the JDK folks had implemented an option where you could specify a ladder)
Setting the MaxRAMPercentage
option look like this:
java -XX:MaxRAMPercentage=75.0 ....
Note that these percentage values are of 'double' type and therefore you must specify them with a decimal dot. You get a somewhat odd error if you use "75" instead of "75.0".
It is a Generic Type Parameter.
A generic type parameter allows you to specify an arbitrary type T to a method at compile-time, without specifying a concrete type in the method or class declaration.
For example:
public T[] Reverse<T>(T[] array)
{
var result = new T[array.Length];
int j=0;
for(int i=array.Length - 1; i>= 0; i--)
{
result[j] = array[i];
j++;
}
return result;
}
reverses the elements in an array. The key point here is that the array elements can be of any type, and the function will still work. You specify the type in the method call; type safety is still guaranteed.
So, to reverse an array of strings:
string[] array = new string[] { "1", "2", "3", "4", "5" };
var result = reverse(array);
Will produce a string array in result
of { "5", "4", "3", "2", "1" }
This has the same effect as if you had called an ordinary (non-generic) method that looks like this:
public string[] Reverse(string[] array)
{
var result = new string[array.Length];
int j=0;
for(int i=array.Length - 1; i >= 0; i--)
{
result[j] = array[i];
j++;
}
return result;
}
The compiler sees that array
contains strings, so it returns an array of strings. Type string
is substituted for the T
type parameter.
Generic type parameters can also be used to create generic classes. In the example you gave of a SampleCollection<T>
, the T
is a placeholder for an arbitrary type; it means that SampleCollection
can represent a collection of objects, the type of which you specify when you create the collection.
So:
var collection = new SampleCollection<string>();
creates a collection that can hold strings. The Reverse
method illustrated above, in a somewhat different form, can be used to reverse the collection's members.
I got this with data driven tests using:
Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)
The problem is the above driver only is 32 bit. I had switched visual studio testsettings file to 64 bit to test a 64-bit-only application.
Switching back to 32 bit in the testsettings file fixed the issue.
Here is a short example of applying a function to each row of a matrix. (Here, the function applied normalizes every row to 1.)
Note: The result from the apply()
had to be transposed using t()
to get the same layout as the input matrix A
.
A <- matrix(c(
0, 1, 1, 2,
0, 0, 1, 3,
0, 0, 1, 3
), nrow = 3, byrow = TRUE)
t(apply(A, 1, function(x) x / sum(x) ))
Result:
[,1] [,2] [,3] [,4]
[1,] 0 0.25 0.25 0.50
[2,] 0 0.00 0.25 0.75
[3,] 0 0.00 0.25 0.75
This is known as a Shebang
:
http://en.wikipedia.org/wiki/Shebang_(Unix)
#!interpreter [optional-arg]
A shebang is only relevant when a script has the execute permission (e.g. chmod u+x script.sh).
When a shell executes the script it will use the specified interpreter.
Example:
#!/bin/bash
# file: foo.sh
echo 1
$ chmod u+x foo.sh
$ ./foo.sh
1
This is a very low-level exception, which is ORA-17410.
It may happen for several reasons:
A temporary problem with networking.
Wrong JDBC driver version.
Some issues with a special data structure (on database side).
Database bug.
In my case, it was a bug we hit on the database, which needs to be patched.
It can be done at easily like as:
<a id="send-thoughts" href="">Click</a>
<textarea id="message"></textarea>
$("a#send-thoughts").click(function() {
var thought = $("#message").val();
alert(thought);
});
UPDATE tbl_ClientNotes
SET
ordering=ISNULL@ordering,ordering),
title=isnull(@title,title),
content=isnull(@content,content)
WHERE id=@id
I think I remember seeing before that if you are updating to the same value SQL Server will actually recognize this and won't do an unnecessary write.
I have no idea what linux distribution "ubuntu centOS" is. Ubuntu and CentOS are two different distributions.

Coop's answer is excellent.
However it depends on jQuery, here is a version that has no dependencies:
HTML
<div id="sticky" class="sticky"></div>
CSS
.sticky {
width: 100%
}
.fixed {
position: fixed;
top:0;
}
JS
(This uses eyelidlessness's answer for finding offsets in Vanilla JS.)
function findOffset(element) {
var top = 0, left = 0;
do {
top += element.offsetTop || 0;
left += element.offsetLeft || 0;
element = element.offsetParent;
} while(element);
return {
top: top,
left: left
};
}
window.onload = function () {
var stickyHeader = document.getElementById('sticky');
var headerOffset = findOffset(stickyHeader);
window.onscroll = function() {
// body.scrollTop is deprecated and no longer available on Firefox
var bodyScrollTop = document.documentElement.scrollTop || document.body.scrollTop;
if (bodyScrollTop > headerOffset.top) {
stickyHeader.classList.add('fixed');
} else {
stickyHeader.classList.remove('fixed');
}
};
};
Example
You can use the @RequestHeader
annotation with HttpHeaders
method parameter to gain access to all request headers:
@RequestMapping(value = "/restURL")
public String serveRest(@RequestBody String body, @RequestHeader HttpHeaders headers) {
// Use headers to get the information about all the request headers
long contentLength = headers.getContentLength();
// ...
StreamSource source = new StreamSource(new StringReader(body));
YourObject obj = (YourObject) jaxb2Mashaller.unmarshal(source);
// ...
}
If you want to use devel
or feature
branch, or you haven’t published a certain package to the NPM registry, or you can’t because it’s a private module, then you can point to a git://
URI instead of a version number in your package.json
:
"dependencies": {
"public": "git://github.com/user/repo.git#ref",
"private": "git+ssh://[email protected]:user/repo.git#ref"
}
The #ref
portion is optional, and it can be a branch (like master
), tag (like 0.0.1
) or a partial or full commit id.
I think the best way to work with dates between C# and SQL is, of course, use parametrized queries, and always work with DateTime objects on C# and the ToString() formating options it provides.
You better execute set datetime <format>
(here you have the set dateformat explanation on MSDN) before working with dates on SQL Server so you don't get in trouble, like for example set datetime ymd
. You only need to do it once per connection because it mantains the format while open, so a good practice would be to do it just after openning the connection to the database.
Then, you can always work with 'yyyy-MM-dd HH:mm:ss:ffff' formats.
To pass the DateTime object to your parametrized query you can use DateTime.ToString('yyyy-MM-dd HH:mm:ss:ffff')
.
For parsing weird formatted dates on C# you can use DateTime.ParseExact()
method, where you have the option to specify exactly what the input format is: DateTime.ParseExact(<some date string>, 'dd/MM-yyyy',CultureInfo.InvariantCulture)
. Here you have the DateTime.ParseExact() explanation on MSDN)
Something I did recently, hope it helps. I have a list of dictionaries and wanted to add a value to some existing documents.
for item in my_list:
my_collection.update({"_id" : item[key] }, {"$set" : {"New_col_name" :item[value]}})
if($("#id").length) /*exists*/
if(!$("#id").length) /*doesn't exist*/
In my case, I created a new ChildComponent in Parentcomponent whereas both in the same module but Parent is registered in a shared module so I created ChildComponent using CLI which registered Child in the current module but my parent was registered in the shared module.
So register the ChildComponent in Shared Module manually.
Using the constraints
features UniqueConstraint
is preferred over unique_together.
From the Django documentation for unique_together
:
Use UniqueConstraint with the constraints option instead.
UniqueConstraint provides more functionality than unique_together.
unique_together may be deprecated in the future.
For example:
class Volume(models.Model):
id = models.AutoField(primary_key=True)
journal_id = models.ForeignKey(Journals, db_column='jid', null=True, verbose_name="Journal")
volume_number = models.CharField('Volume Number', max_length=100)
comments = models.TextField('Comments', max_length=4000, blank=True)
class Meta:
constraints = [
models.UniqueConstraint(fields=['journal_id', 'volume_number'], name='name of constraint')
]
Assuming it is OK that the operation is not atomic, you can do:
if (std::ifstream(name))
{
std::cout << "File already exists" << std::endl;
return false;
}
std::ofstream file(name);
if (!file)
{
std::cout << "File could not be created" << std::endl;
return false;
}
...
Note that this doesn't work if you run multiple threads trying to create the same file, and certainly will not prevent a second process from "interfering" with the file creation because you have TOCTUI problems. [We first check if the file exists, and then create it - but someone else could have created it in between the check and the creation - if that's critical, you will need to do something else, which isn't portable].
A further problem is if you have permissions such as the file is not readable (so we can't open it for read) but is writeable, it will overwrite the file.
In MOST cases, neither of these things matter, because all you care about is telling someone that "you already have a file like that" (or something like that) in a "best effort" approach.
Easy solution for whom using VS Code
I've been getting this error for a while. Most of the answers works. But I found a different solution. If you don't want to deal with node.js
or any other solution in here and you are working with an HTML file (calling functions from another js file or fetch json api's) try to use Live Server extension.
It allows you to open a live server easily. And because of it creates localhost
server, the problem is resolving. You can simply start the localhost
by open a HTML file and right-click on the editor and click on Open with Live Server
.
It basically load the files using http://localhost/index.html
instead of using file://...
.
EDIT
It is not necessary to have a .html
file. You can start the Live Server with shortcuts.
Hit
(alt+L, alt+O)
to Open the Server and(alt+L, alt+C)
to Stop the server. [On MAC,cmd+L, cmd+O
andcmd+L, cmd+C
]
Hope it will help someone :)
ContextLoaderListener
is optional. Just to make a point here: you can boot up a Spring application without ever configuring ContextLoaderListener
, just a basic minimum web.xml

Create a file called dispatcher-servlet.xml
and store it under WEB-INF
. Since we mentioned index.jsp

You could use the 'isActive' prop like so:
const { router } = this.context;
if (router.isActive('/login')) {
router.push('/');
}
isActive will return a true or false.

In addition to the above mentioned answers: I wanted to start a job with a simple parameter passed to a second pipeline and found the answer on http://web.archive.org/web/20160209062101/https://dzone.com/refcardz/continuous-delivery-with-jenkins-workflow

How to include the jars of your project into your runnable jar:
I'm using Eclipse Version: 3.7.2 running on Ubuntu 12.10. I'll also show you how to make the build.xml
so you can do the ant jar
from command line and create your jar with other imported jars extracted into it.
Basically you ask Eclipse to construct the build.xml that imports your libraries into your jar for you.
Fire up Eclipse and make a new Java project, make a new package 'mypackage', add your main class: Runner
Put this code in there.
Now include the mysql-connector-java-5.1.28-bin.jar
from Oracle which enables us to write Java to connect to the MySQL database. Do this by right clicking the project -> properties -> java build path -> Add External Jar -> pick mysql-connector-java-5.1.28-bin.jar.
Run the program within eclipse, it should run, and tell you that the username/password is invalid which means Eclipse is properly configured with the jar.
In Eclipse go to File
-> Export
-> Java
-> Runnable Jar File
. You will see this dialog:
Make sure to set up the 'save as ant script' checkbox. That is what makes it so you can use the commandline to do an ant jar
later.
Then go to the terminal and look at the ant script:
So you see, I ran the jar and it didn't error out because it found the included mysql-connector-java-5.1.28-bin.jar
embedded inside Hello.jar
.
Look inside Hello.jar: vi Hello.jar
and you will see many references to com/mysql/jdbc/stuff.class
To do ant jar
on the commandline to do all this automatically: Rename buildant.xml
to build.xml
, and change the target name from create_run_jar
to jar
.
Then, from within MyProject
you type ant jar
and boom. You've got your jar inside MyProject. And you can invoke it using java -jar Hello.jar
and it all works.
Try this:
\?(.*)
The parentheses are a capturing group that you can use to extract the part of the string you are interested in.
If the string can contain new lines you may have to use the "dot all" modifier to allow the dot to match the new line character. Whether or not you have to do this, and how to do this, depends on the language you are using. It appears that you forgot to mention the programming language you are using in your question.
Another alternative that you can use if your language supports fixed width lookbehind assertions is:
(?<=\?).*
You may also use PSCredential.GetNetworkCredential() :
$SecurePassword = Get-Content C:\Users\tmarsh\Documents\securePassword.txt | ConvertTo-SecureString
$UnsecurePassword = (New-Object PSCredential "user",$SecurePassword).GetNetworkCredential().Password
hive --outputformat=csv2 -e "select * from yourtable" > my_file.csv
or
hive --outputformat=csv2 -e "select * from yourtable" > [your_path]/file_name.csv
For tsv, just change csv to tsv in the above queries and run your queries
After use codevar json = @Html.Raw(Json.Encode(@Model.CollegeInformationlist));
You need use JSON.parse(JSON.stringify(json))
;
you can use the keyword 'In' and pass the List argument. e.g : findByInventoryIdIn
List<AttributeHistory> findByValueIn(List<String> values);
I found the simplest solution:
git commit -am'save'
That's all,you will work around git commit message stuff.
you can even save that commend to a bash or other stuff to make it more simple.
Our team members always write those messages,but almost no one will see those message again.
Commit message is a time-kill stuff at least in our team,so we ignore it.
You can use the collate clause in a query (I can't find my example right now, so my syntax is probably wrong - I hope it points you in the right direction)
select sone_field collate SQL_Latin1_General_CP850_CI_AI
from table_1
inner join table_2
on (table_1.field collate SQL_Latin1_General_CP850_CI_AI = table_2.field)
where whatever
Try just
sudo service mysql restart
It worked for me
Numeric defines the TOTAL number of digits, and then the number after the decimal.
A numeric(3,2) can only hold up to 9.99.
Advantages:
allows you to use multiple versions of Node and without sudo
is analogous to Ruby RVM and Python Virtualenv, widely considered best practice in Ruby and Python communities
downloads a pre-compiled binary where possible, and if not it downloads the source and compiles one for you
Tested in Ubuntu 17.10:
curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | sh
source ~/.nvm/nvm.sh
nvm install 0.9.0
nvm install 0.9.9
nvm use 0.9.0
node --version
#v0.9.0
nvm use 0.9.9
node --version
#v0.9.9
For the particular case of the most recent long term support version (recommended if you can choose):
nvm install --lts
nvm use --lts
npm --version
npm install --global vaca
vaca
Since the sourcing has to be done for every new shell, the install script hacks adds some auto sourcing to the end of your .barshrc
. That works, but I prefer to remove the auto-added one and add my own:
f="$HOME/.nvm/nvm.sh"
if [ -r "$f" ]; then
. "$f" &>'/dev/null'
nvm use --lts &>'/dev/null'
fi
With this setup, you get for example:
which node
gives:
/home/ciro/.nvm/versions/node/v0.9.0/bin/node
and:
which vaca
gives:
/home/ciro/.nvm/versions/node/v0.9.0/bin/vaca
and if we want to use the globally installed module:
npm link vaca
node -e 'console.log(require.resolve("vaca"))'
gives:
/home/ciro/.nvm/versions/node/v0.9.0/lib/node_modules/vaca/index.js
so we see that everything is completely contained inside the specific node version.
Same problem here, solved.
I will explain the problem and the solution, to help others.
My software is:
Windows 7
Eclipse 4.4.1 (Luna SR1)
m2e 1.5.0.20140606-0033
(from eclipse repository: http://download.eclipse.org/releases/luna)
And I'm accessing internet through a proxy.
My problem was the same:
After a lot of try-and-error, and reading a lot of pages, I've finally found a solution to fix it. Some important points of the solution:
The solution is:
<settings> <proxies> <proxy> <active>true</active> <protocol>http</protocol> <host>YOUR.PROXY.IP.OR.NAME</host> <port>YOUR PROXY PORT</port> <username>YOUR PROXY USERNAME (OR EMPTY IF NOT REQUIRED)</username> <password>YOUR PROXY PASSWORD (OR EMPTY IF NOT REQUIRED)</password> <nonProxyHosts>YOUR PROXY EXCLUSION HOST LIST (OR EMPTY)</nonProxyHosts> </proxy> </proxies> </settings>
Finally, I would like to give a suggestion to m2e developers, to make config easier. After installing m2e from the internet (from a repository), m2e should check if Eclipse is using a proxy (Preferences > General > Network Connections). If Eclipse is using a proxy, the m2e should show a dialog to the user:
m2e has detected that Eclipse is using a proxy to access to the internet.
Would you like me to create a User settings file (settings.xml) for the embedded
Maven software?
[ Yes ] [ No ]
If the user clicks on Yes, then m2e should create automatically the "settings.xml" file by copying proxy values from Eclipse preferences.

Here is what i use in my Bash script to test if Docker is running or not
# Check if docker is running

echo "Docker does not seem to be running, run it first and retry"

<?php
$url = 'your repository here';
$output = `svn info $url`;
echo "<pre>$output</pre>";
?>
You can get the output in XML like so:
$output = `svn info $url --xml`;
If there is an error then the output will be directed to stderr. To capture stderr in your output use thusly:
$output = `svn info $url 2>&1`;
Try this, if you use a DateTimeOffset
, it will also take care of the timezone
date1 = date1.LocalDateTime.Date;
If you need to add hours, use this:
date1 = date1.LocalDateTime.Date;
date1 = date1.AddHours(23).AddMinutes(59).AddSeconds(59);
Add services.AddSingleton(); in your ConfigureServices method of Startup.cs file of your project.
public void ConfigureServices(IServiceCollection services)
{
services.AddRazorPages();
// To register interface with its concrite type
services.AddSingleton<IEmployee, EmployeesMockup>();
}

If you truly want to confirm that a variable is not null and not an empty string specifically, you would write:
if(data !== null && data !== '') {
// do something
}
Notice that I changed your code to check for type equality (!==
|===
).
If, however you just want to make sure, that a code will run only for "reasonable" values, then you can, as others have stated already, write:
if (data) {
// do something
}
Since, in javascript, both null values, and empty strings, equals to false (i.e. null == false
).
The difference between those 2 parts of code is that, for the first one, every value that is not specifically null or an empty string, will enter the if
. But, on the second one, every true-ish value will enter the if
: false
, 0
, null
, undefined
and empty strings, would not.

This error arise from the fact that you are trying to define an object of shape (0,) as an object of shape (2,). If you append what you want without forcing it to be equal to result[0] there is no any issue:
b = np.append([result[0]], [1,2])
But when you define result[0] = b you are equating objects of different shapes, and you can not do this. What are you trying to do?
xhr.file = file;
; the file object is not supposed to be attached this way.xhr.send(file)
doesn't send the file. You have to use the FormData
object to wrap the file into a multipart/form-data
post data object:
var formData = new FormData();
formData.append("thefile", file);
xhr.send(formData);
After that, the file can be access in $_FILES['thefile']
(if you are using PHP).
Remember, MDC and Mozilla Hack demos are your best friends.
EDIT: The (2) above was incorrect. It does send the file, but it would send it as raw post data. That means you would have to parse it yourself on the server (and it's often not possible, depend on server configuration). Read how to get raw post data in PHP here.

My understanding after reading the link offered by G.Grothendieck is that %>% is an operator that pipes functions. This helps readability and productivity as it's easier to follow the flow of multiple functions through these pipes than going backwards when multiple function are nested.
These are the preferred methods:
var item = Items.SingleOrDefault(x => x.Id == 123);
Or
var item = Items.Single(x => x.Id == 123);
For some reason none of the above Answers worked for me. As I need to pass several extra vars to my playbook in Ansbile 2.2.0, this is how I got it working (note the -e option before each var):

The Singleton:
package com.domain.packagename;
import android.content.Context;
/**
* Created by Versa on 10.09.15.
*/
public class ApplicationContextSingleton {
private static PrefsContextSingleton mInstance;
private Context context;
public static ApplicationContextSingleton getInstance() {
if (mInstance == null) mInstance = getSync();
return mInstance;
}
private static synchronized ApplicationContextSingleton getSync() {
if (mInstance == null) mInstance = new PrefsContextSingleton();
return mInstance;
}
public void initialize(Context context) {
this.context = context;
}
public Context getApplicationContext() {
return context;
}
}
Initialize the Singleton in your Application
subclass:
package com.domain.packagename;
import android.app.Application;
/**
* Created by Versa on 25.08.15.
*/
public class mApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
ApplicationContextSingleton.getInstance().initialize(this);
}
}
If I´m not wrong, this gives you a hook to applicationContext everywhere, call it with ApplicationContextSingleton.getInstance.getApplicationContext();
You shouldn´t need to clear this at any point, as when application closes, this goes with it anyway.
Remember to update AndroidManifest.xml
to use this Application
subclass:
<?xml version="1.0" encoding="utf-8"?>
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.domain.packagename"
>
<application
android:allowBackup="true"
android:name=".mApplication" <!-- This is the important line -->
android:label="@string/app_name"
android:theme="@style/AppTheme"
android:icon="@drawable/app_icon"
>
Now you should be able to use ApplicationContextSingleton.getInstance().getApplicationContext().getResources() from anywhere, also the very few places where application subclasses can´t.
Please let me know if you see anything wrong here, thank you. :)
A solution with works with Python 2.X and Python 3.X makes use of the Python 2 and 3 compatibility library six

response = urlopen(link)
content = response.read()
print(content)
here is the easiest way to add progress bar in android Web View.
Add a boolean field in your activity/fragment
private boolean isRedirected;
This boolean will prevent redirection of web pages cause of dead links.Now you can just pass your WebView object and web Url into this method.
private void startWebView(WebView webView,String url) {
webView.setWebViewClient(new WebViewClient() {
ProgressDialog progressDialog;
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
isRedirected = true;
return false;
}
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
isRedirected = false;
}
public void onLoadResource (WebView view, String url) {
if (!isRedirected) {
if (progressDialog == null) {
progressDialog = new ProgressDialog(SponceredDetailsActivity.this);
progressDialog.setMessage("Loading...");
progressDialog.show();
}
}
}
public void onPageFinished(WebView view, String url) {
try{
isRedirected=true;
if (progressDialog.isShowing()) {
progressDialog.dismiss();
progressDialog = null;
}
}catch(Exception exception){
exception.printStackTrace();
}
}
});
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(url);
}
Here when start loading it will call onPageStarted
. Here i setting Boolean field is false. But when page load finish it will come to onPageFinished
method and here Boolean field is set to true. Sometimes if url is dead it will redirected and it will come to onLoadResource()
before onPageFinished
method. For this reason it will not hiding the progress bar. To prevent this i am checking if (!isRedirected)
in onLoadResource()
in onPageFinished()
method before dismissing the Progress Dialog you can write your 10 second time delay code
That's it. Happy coding :)

Late joining this conversation to shed light on a mildly interesting factoid for web-facing, analytics-aware websites. Passing the mic over to Michael Papworth:
https://github.com/michaelpapworth/jQuery.navigate
"When using website analytics, window.location is not sufficient due to the referer not being passed on the request. The plugin resolves this and allows for both aliased and parametrised URLs."
If one examines the code what it does is this:
var methods = {
'goTo': function (url) {
// instead of using window.location to navigate away
// we use an ephimeral link to click on and thus ensure
// the referer (current url) is always passed on to the request
$('<a></a>').attr("href", url)[0].click();
},
...
};

Doing the same on windows seems to kill the process fine even if signal is handled (but that might be due to windows not using signals to destroy).
Actually i found Java - Process.destroy() source code for Linux related thread and openjava implementation seems to use -TERM as well, which seems very wrong.
there is a simpler way of checking if a variable is an integer. you can use $.isNumeric() function. e.g.
$.isNumeric( 10 ); // true
this will return true but if you put a string in place of the 10, you will get false.
I hope this works for you.
Hi if your are looking for simple android image sliding with circle indicator you can download the complete code from here http://javaant.com/viewpager-with-circle-indicator-in-android/#.VysQQRV96Hs . please check the live demo which will give the clear idea.
You do realize that format has nothing to do with how SQL Server stores datetime, right?
You can use set dateformat
for each session. There is no setting for database only.
If you use parameters for data insert or update or where filtering you won't have any problems with that.
To Enable WiFi:
WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
wifi.setWifiEnabled(true);
To Disable WiFi:
WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
wifi.setWifiEnabled(false);
Note: To access with WiFi state, we have to add following permissions inside the AndroidManifest.xml file:
android.permission.ACCESS_WIFI_STATE
android.permission.UPDATE_DEVICE_STATS
android.permission.CHANGE_WIFI_STATE
If you create your test classes in a seperate folder which you then add to your build path,
Then you could make the test class an inner class of the class under test by using package correctly to set the namespace. This gives it access to private fields and methods.
But dont forget to remove the folder from the build path for your release build.
You have to mock the module and set the spy by yourself:
import myModule from '../myModule';
import dependency from '../dependency';
jest.mock('../dependency', () => ({
doSomething: jest.fn()
}))
describe('myModule', () => {
it('calls the dependency with double the input', () => {
myModule(2);
expect(dependency.doSomething).toBeCalledWith(4);
});
});
Another addition: be careful when replacing multiples and converting the type of the column back from object to float. If you want to be certain that your None
's won't flip back to np.NaN
's apply @andy-hayden's suggestion with using pd.where
.
Illustration of how replace can still go 'wrong':
In [1]: import pandas as pd
In [2]: import numpy as np
In [3]: df = pd.DataFrame({"a": [1, np.NAN, np.inf]})
In [4]: df
Out[4]:
a
0 1.0
1 NaN
2 inf
In [5]: df.replace({np.NAN: None})
Out[5]:
a
0 1
1 None
2 inf
In [6]: df.replace({np.NAN: None, np.inf: None})
Out[6]:
a
0 1.0
1 NaN
2 NaN
In [7]: df.where((pd.notnull(df)), None).replace({np.inf: None})
Out[7]:
a
0 1.0
1 NaN
2 NaN
For substracting in moment.js:
moment().subtract(1, 'months').format('MMM YYYY');
Documentation:
http://momentjs.com/docs/#/manipulating/subtract/
Before version 2.8.0, the moment#subtract(String, Number) syntax was also supported. It has been deprecated in favor of moment#subtract(Number, String).
moment().subtract('seconds', 1); // Deprecated in 2.8.0
moment().subtract(1, 'seconds');
As of 2.12.0 when decimal values are passed for days and months, they are rounded to the nearest integer. Weeks, quarters, and years are converted to days or months, and then rounded to the nearest integer.
moment().subtract(1.5, 'months') == moment().subtract(2, 'months')
moment().subtract(.7, 'years') == moment().subtract(8, 'months') //.7*12 = 8.4, rounded to 8
If you want first 2 letters and last 2 letters of a string then you can use the following code:
name = "India"
name[0:2]="In"
names[-2:]="ia"
AFAIK, you have to convert it to grayscale and then threshold it to binary.
1. Read the image as a grayscale image If you're reading the RGB image from disk, then you can directly read it as a grayscale image, like this:
// C
IplImage* im_gray = cvLoadImage("image.jpg",CV_LOAD_IMAGE_GRAYSCALE);
// C++ (OpenCV 2.0)
Mat im_gray = imread("image.jpg",CV_LOAD_IMAGE_GRAYSCALE);
2. Convert an RGB image im_rgb
into a grayscale image: Otherwise, you'll have to convert the previously obtained RGB image into a grayscale image
// C
IplImage *im_rgb = cvLoadImage("image.jpg");
IplImage *im_gray = cvCreateImage(cvGetSize(im_rgb),IPL_DEPTH_8U,1);
cvCvtColor(im_rgb,im_gray,CV_RGB2GRAY);
// C++
Mat im_rgb = imread("image.jpg");
Mat im_gray;
cvtColor(im_rgb,im_gray,CV_RGB2GRAY);
3. Convert to binary You can use adaptive thresholding or fixed-level thresholding to convert your grayscale image to a binary image.
E.g. in C you can do the following (you can also do the same in C++ with Mat and the corresponding functions):
// C
IplImage* im_bw = cvCreateImage(cvGetSize(im_gray),IPL_DEPTH_8U,1);
cvThreshold(im_gray, im_bw, 128, 255, CV_THRESH_BINARY | CV_THRESH_OTSU);
// C++
Mat img_bw = im_gray > 128;
In the above example, 128 is the threshold.
4. Save to disk
// C
cvSaveImage("image_bw.jpg",img_bw);
// C++
imwrite("image_bw.jpg", img_bw);
I presume that your problem with background-image
is that it would be inefficient with a source for each image inside a stylesheet. My suggestion is to set the source inline:
<div style = 'background-image: url(image.gif)'></div>
div {
background-repeat: no-repeat;
background-position: 50%;
border-radius: 50%;
width: 100px;
height: 100px;
}
I am working with sdk 23.1.0 and gradle 1.3.1. I created a new project edited nothing and got the aidl error. I went into my project gradle file and changed tool to 22.0.1 instead of 23.1.0 and it worked:
compileSdkVersion 23
buildToolsVersion "22.0.1" //"23.1.0"
What you want is File.listFiles(FileNameFilter filter)
.
That will give you a list of the files in the directory you want that match a certain filter.
The code will look similar to:
// your directory
File f = new File("C:\\example");
File[] matchingFiles = f.listFiles(new FilenameFilter() {
public boolean accept(File dir, String name) {
return name.startsWith("temp") && name.endsWith("txt");
}
});
With 1.1.1, I used the following to fix the scale between 0.0 and 1.0:

}

Step 1: Hook your HTML number input box to an onchange event
myHTMLNumberInput.onchange = setTwoNumberDecimal;
or in the HTML code
<input type="number" onchange="setTwoNumberDecimal" min="0" max="10" step="0.25" value="0.00" />
Step 2: Write the setTwoDecimalPlace
method
function setTwoNumberDecimal(event) {
this.value = parseFloat(this.value).toFixed(2);
}
You can alter the number of decimal places by varying the value passed into the toFixed()
method. See MDN docs.
toFixed(2); // 2 decimal places
toFixed(4); // 4 decimal places
toFixed(0); // integer
I develop a good solution, I know there is much If

if startCounting:
count_digits = count_digits + 1
resp = resp + number_str[i]
if count_digits == digits:

I need to select every production with a category that doesn't contain "Business"
Although I upvoted @Arran's answer as correct, I would also add this... Strictly interpreted, the OP's specification would be implemented as
//production[category[not(contains(., 'Business'))]]
rather than
//production[not(contains(category, 'Business'))]
The latter selects every production whose first category
child doesn't contain "Business". The two XPath expressions will behave differently when a production
has no category
children, or more than one.
It doesn't make any difference in practice as long as every <production>
has exactly one <category>
child, as in your short example XML. Whether you can always count on that being true or not, depends on various factors, such as whether you have a schema that enforces that constraint. Personally, I would go for the more robust option, since it doesn't "cost" much... assuming your requirement as stated in the question is really correct (as opposed to e.g. 'select every production that doesn't have a category that contains "Business"').

However, IN will stop way before that but it's not precise.
You end up with memory errors but I can't recall the exact error. A huge IN will be inefficient anyway.
Edit: Remus reminded me: the error is about "stack size"
Important note: If you remember the position of your application and shutdown and then start up again at that position, keep in mind that the user's monitor configuration may have changed while your application was closed.
Laptop users, for example, frequently change their display configuration. When docked there may be a 2nd monitor that disappears when undocked. If the user closes an application that was running on the 2nd monitor and the re-opens the application when the monitor is disconnected, restoring the window to the previous coordinates will leave it completely off-screen.
To figure out how big the display really is, check out GetSystemMetrics.
DROP TABLE IF EXISTS [table_name]
it first checks if the table exists, if it does it deletes the table while
DROP TABLE [table_name]
it deletes without checking, so if it doesn't exist it exits with an error
console.log(document.getElementById('xx') ) evaluates to null.
document.getElementById('xx') !=null evaluates to false
You should use document.getElementById('xx') !== null
as it is a stronger equality check.
Try adding return false;
in your click callback like this -
$(document).ready(function() {
$('.popup').click(function(event) {
window.open($(this).attr("href"), "popupWindow", "width=600,height=600,scrollbars=yes");
return false;
});
});
Assuming the second window is defined as public partial class Window2 : Window
, you can do it by:
Window2 win2 = new Window2();
win2.Show();
From: jQuery text truncation (read more style)
Try this:
var title = "This is your title";
var shortText = jQuery.trim(title).substring(0, 10)
.split(" ").slice(0, -1).join(" ") + "...";
And you can also use a plugin:
As a extension of String
String.prototype.trimToLength = function(m) {
return (this.length > m)
? jQuery.trim(this).substring(0, m).split(" ").slice(0, -1).join(" ") + "..."
: this;
};
Use as
"This is your title".trimToLength(10);
Here is syntax for showing hours and minutes for a field coming out of a SELECT statement. In this example, the SQL field is named "UpdatedOnAt" and is a DateTime. Tested with MS SQL 2014.
SELECT Format(UpdatedOnAt ,'hh:mm') as UpdatedOnAt from MyTable
I like the format that shows the day of the week as a 3-letter abbreviation, and includes the seconds:
SELECT Format(UpdatedOnAt ,'ddd hh:mm:ss') as UpdatedOnAt from MyTable
The "as UpdatedOnAt" suffix is optional. It gives you a column heading equal tot he field you were selecting to begin with.
<?xml version="1.0"?>
<configuration>
<appSettings>
<!--FailIfMissing=false -->
<add key="DbSQLite" value="data source=|DataDirectory|DB.db3;Pooling=true;FailIfMissing=false"/>
</appSettings>
</configuration>
You can also pad a string to the required length using Guava's Strings.padEnd(String input, int minLength, char padding)
As in your example, the fit_start_time
is not later than the fit_end_time
.
Try it the other way round:
var fit_start_time = $("#fit_start_time").val(); //2013-09-5
var fit_end_time = $("#fit_end_time").val(); //2013-09-10
if(Date.parse(fit_start_time) <= Date.parse(fit_end_time)){
alert("Please select a different End Date.");
}
Update
Your code implies that you want to see the alert
with the current variables you have. If this is the case then the above code is correct. If you're intention (as per the implication of the alert message
) is to make sure their fit_start_time
variable is a date that is before the fit_end_time
, then your original code is fine, but the data you're getting from the jQuery .val()
methods is not parsing correctly. It would help if you gave us the actual HTML which the selector is sniffing at.
For me is working this way, using port and security (I had issues to send emails from gmail using PHP without security settings)
I hope will help someone.
var sendEmail = function(somedata){
var smtpConfig = {
host: 'smtp.gmail.com',
port: 465,
secure: true, // use SSL,
// you can try with TLS, but port is then 587
auth: {
user: '***@gmail.com', // Your email id
pass: '****' // Your password
}
};
var transporter = nodemailer.createTransport(smtpConfig);
// replace hardcoded options with data passed (somedata)
var mailOptions = {
from: '[email protected]', // sender address
to: '[email protected]', // list of receivers
subject: 'Test email', // Subject line
text: 'this is some text', //, // plaintext body
html: '<b>Hello world ?</b>' // You can choose to send an HTML body instead
}
transporter.sendMail(mailOptions, function(error, info){
if(error){
return false;
}else{
console.log('Message sent: ' + info.response);
return true;
};
});
}
exports.contact = function(req, res){
// call sendEmail function and do something with it
sendEmail(somedata);
}
all the config are listed here (including examples)
I think you're confused about types here. You'll only get that result if you're multiplying a string. Start the interpreter and try this:
>>> print "1" * 9
111111111
>>> print 1 * 9
9
>>> print int("1") * 9
9
So make sure the first operand is an integer (and not a string), and it will work.
I used:
git reset --hard
I lost some changes, but this is ok.
breast$class <- as.numeric(as.character(breast$class))
If you have many columns to convert to numeric
indx <- sapply(breast, is.factor)
breast[indx] <- lapply(breast[indx], function(x) as.numeric(as.character(x)))
Another option is to use stringsAsFactors=FALSE
while reading the file using read.table
or read.csv
Just in case, other options to create/change columns
breast[,'class'] <- as.numeric(as.character(breast[,'class']))
or
breast <- transform(breast, class=as.numeric(as.character(breast)))
Currying is a transformation that can be applied to functions to allow them to take one less argument than previously.
For example, in F# you can define a function thus:-
let f x y z = x + y + z
Here function f takes parameters x, y and z and sums them together so:-
f 1 2 3
Returns 6.
From our definition we can can therefore define the curry function for f:-
let curry f = fun x -> f x
Where 'fun x -> f x' is a lambda function equivilent to x => f(x) in C#. This function inputs the function you wish to curry and returns a function which takes a single argument and returns the specified function with the first argument set to the input argument.
Using our previous example we can obtain a curry of f thus:-
let curryf = curry f
We can then do the following:-
let f1 = curryf 1
Which provides us with a function f1 which is equivilent to f1 y z = 1 + y + z. This means we can do the following:-
f1 2 3
Which returns 6.
This process is often confused with 'partial function application' which can be defined thus:-
let papply f x = f x
Though we can extend it to more than one parameter, i.e.:-
let papply2 f x y = f x y
let papply3 f x y z = f x y z
etc.
A partial application will take the function and parameter(s) and return a function that requires one or more less parameters, and as the previous two examples show is implemented directly in the standard F# function definition so we could achieve the previous result thus:-
let f1 = f 1
f1 2 3
Which will return a result of 6.
In conclusion:-
The difference between currying and partial function application is that:-
Currying takes a function and provides a new function accepting a single argument, and returning the specified function with its first argument set to that argument. This allows us to represent functions with multiple parameters as a series of single argument functions. Example:-
let f x y z = x + y + z
let curryf = curry f
let f1 = curryf 1
let f2 = curryf 2
f1 2 3
6
f2 1 3
6
Partial function application is more direct - it takes a function and one or more arguments and returns a function with the first n arguments set to the n arguments specified. Example:-
let f x y z = x + y + z
let f1 = f 1
let f2 = f 2
f1 2 3
6
f2 1 3
6
In res/drawable
folder,
1. Create a new Drawable Resources
.
2. Input file name.
A new file will be created inside the res/drawable
folder.
Replace this code inside the newly created file and replace ic_action_back
with your drawable file name.
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="@drawable/ic_action_back"
android:tint="@color/color_primary_text" />
Now, you can use it with Resource ID, R.id.filename
.

gcc is a rich and complex "orchestrating" program that calls many other programs to perform its duties. For the specific purpose of seeing where #include "goo"
and #include <zap>
will search on your system, I recommend:
$ touch a.c
$ gcc -v -E a.c
...
#include "..." search starts here:
#include <...> search starts here:
/usr/local/include
/usr/lib/gcc/i686-apple-darwin9/4.0.1/include
/usr/include
/System/Library/Frameworks (framework directory)
/Library/Frameworks (framework directory)
End of search list.
# 1 "a.c"
This is one way to see the search lists for included files, including (if any) directories into which #include "..."
will look but #include <...>
won't. This specific list I'm showing is actually on Mac OS X (aka Darwin) but the commands I recommend will show you the search lists (as well as interesting configuration details that I've replaced with ...
here;-) on any system on which gcc runs properly.
You can use this as follows:

Bart Kiers, your regex has a couple issues. The best way to do that is this:
(.*[a-z].*) // For lower cases
(.*[A-Z].*) // For upper cases
(.*\d.*) // For digits
In this way you are searching no matter if at the beginning, at the end or at the middle. In your have I have a lot of troubles with complex passwords.
It is two problems - is the slashes the right places and is it a valid date. I would suggest you catch input changes and put the slashes in yourself. (annoying for the user)
The interesting problem is whether they put in a valid date and I would suggest exploiting how flexible js is:
function isValidDate(str) {_x000D_
var newdate = new Date();_x000D_
var yyyy = 2000 + Number(str.substr(4, 2));_x000D_
var mm = Number(str.substr(2, 2)) - 1;_x000D_
var dd = Number(str.substr(0, 2));_x000D_
newdate.setFullYear(yyyy);_x000D_
newdate.setMonth(mm);_x000D_
newdate.setDate(dd);_x000D_
return dd == newdate.getDate() && mm == newdate.getMonth() && yyyy == newdate.getFullYear();_x000D_
}_x000D_
console.log(isValidDate('jk'));//false_x000D_
console.log(isValidDate('290215'));//false_x000D_
console.log(isValidDate('290216'));//true_x000D_
console.log(isValidDate('292216'));//false

The thing about collations is that although the database has its own collation, every table, and every column can have its own collation. If not specified it takes the default of its parent object, but can be different.
When you change collation of the database, it will be the new default for all new tables and columns, but it doesn't change the collation of existing objects inside the database. You have to go and change manually the collation of every table and column.
Luckily there are scripts available on the internet that can do the job. I am not going to recommend any as I haven't tried them but here are few links:
http://www.codeproject.com/Articles/302405/The-Easy-way-of-changing-Collation-of-all-Database
Update Collation of all fields in database on the fly
http://www.sqlservercentral.com/Forums/Topic820675-146-1.aspx
If you need to have different collation on two objects or can't change collations - you can still JOIN
between them using COLLATE
command, and choosing the collation you want for join.
SELECT * FROM A JOIN B ON A.Text = B.Text COLLATE Latin1_General_CI_AS
or using default database collation:
SELECT * FROM A JOIN B ON A.Text = B.Text COLLATE DATABASE_DEFAULT

Try using MySQLdb. MySQLdb only supports Python 2.
There is a how to page here: http://www.kitebird.com/articles/pydbapi.html
From the page:
# server_version.py - retrieve and display database server version
import MySQLdb
conn = MySQLdb.connect (host = "localhost",
user = "testuser",
passwd = "testpass",
db = "test")
cursor = conn.cursor ()
cursor.execute ("SELECT VERSION()")
row = cursor.fetchone ()
print "server version:", row[0]
cursor.close ()
conn.close ()
Both Promises and Observables help us dealing with asynchronous operations. They can call certain callbacks when these asynchronous operations are done.
Angular uses Observables which is from RxJS instead of promises for dealing with HTTP
Below are some important differences in promises & Observables.
Try this following
var myJSONObject ={"ircEvent": "PRIVMSG", "method": "newURI", "regex": "^http://.*"};
console.log(myJSONObject);
console.log(myJSONObject.ircEvent);
delete myJSONObject.ircEvent
delete myJSONObject.regex
console.log(myJSONObject);
If you want to know if "1" ou 1 can be casted to a number, you can use this code :
if (isNaN(i*1)) {
console.log('i is not a number');
}
the previous answers didn't work out for me well. I had persisting problems by setting the marker. So i changed the code slightly.

This way worked out for me! You can create Google Maps routing links from your Datebase to to use it as an interactive routing map.
You can use Oracle.ManagedDataAccess.dll instead (download from Oracle), include that dll in you project bin dir, add reference to that dll in the project. In code, "using Oracle.MangedDataAccess.Client". Deploy project to server as usual. No need install Oracle Client on server. No need to add assembly info in web.config.

This code worked for me..

hello i have had same problem an i did the steps with tommer and the problem solved thank you
note :
you don't have to go to that like just do this ;
1)-- Edit your “my.ini” file in c:\xampp\mysql\bin\ Change all default 3306 port entries to a new value 3308
2)--edit your “php.ini” in c:\xampp\php and replace 3306 by 3308
3)--Create the service entry - in Windows command line type
sc.exe create "mysqlweb" binPath= "C:\xampp\mysql\bin\mysqld.exe --defaults-file=c:\xampp\mysql\bin\my.ini mysqlweb"
4)--Open Windows Services and set Startup Type: Automatic, Start the service
One thing to note is that not all libraries will use the same meaning for pi, of course, so it never hurts to know what you're using. For example, the symbolic math library Sympy's representation of pi is not the same as math and numpy:
import math
import numpy
import scipy
import sympy
print(math.pi == numpy.pi)
> True
print(math.pi == scipy.pi)
> True
print(math.pi == sympy.pi)
> False
If your URL is working and loads the file correctly, and you've said that adding the correct
<link rel="stylesheet" type="text/css" href="yourlink.css">
code doesn't fix it, then the only other problem is that's it's an error in the actual .css file. And to advise you on that, we'd need to see the file.
What you can do though is write one basic <div>
tag into your HTML, add in a basic CSS rule into your existing file, then see if you can influence this tag with your new CSS rule.
It's not bulletproof by any means, but it worked for my purposes and maybe it will help someone.
var value = $('input').val();
if(parseInt(value)) {
console.log(value+" is a number.");
}
else {
console.log(value+" is NaN.");
}
In your MainActivity, under onCreate:
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
And in your fragment activity under onResume
:
getActivity().setTitle(R.string.app_name_science);
Optional:- if they show warning of null reference
Objects.requireNonNull(getSupportActionBar()).setDisplayHomeAsUpEnabled(true);
Objects.requireNonNull(getActivity()).setTitle(R.string.app_name_science);
Make sure SQL Server is enabled for TCP/IP (someone may have disabled it)?
This will also help you to check/verify the port number the SQL instance is using (in case someone changed it from the default of port 1433).
Obviously port 1433 (or whatever port SQL is listening on) needs to be unblocked by any firewalls between your machine and the box SQL is running on.
To check SQL's network configuration (requires SQL Server Client Tools installed): Start -> Programs -> SQL Server 200x -> Configuration Tools -> SQL Server Configuration Manager
Connect to the machine you need then expand the Tree Item (LHS) "SQL Server Network Configuration", then pick instance. You should have four options - Shared Memory, Named Pipes, TCP/IP and VIA. You can check that TCP/IP is enabled in the RHS window.
If you double click TCP/IP and hit the "Advanced" tab, you can also view the Port number.
Other thoughts.. Are you using SQL Authentication or Windows (Domain) authentication?
If SQL Authentication (which I assume you are using given you said username and password), are you sure the SQL instance you're connecting to has mixed mode authentication enabled? If not, you have to connect as Administrator and change the default security settings to allow SQL authentication.
If Windows Authentication, could your network be using Kerberos potentially? One would think the VPN credentials would be used for the handshake. I'd check your account has appropriate login rights.
While trying to solve this for myself, I noticed that it's actually possible to retain the scrolling of the page and focus of the input while disabling number changes by attempting to re-fire the caught event on the parent element of the <input type="number"/>
on which it was caught, simply like this:
e.target.parentElement.dispatchEvent(e);
However, this causes an error in browser console, and is probably not guaranteed to work everywhere (I only tested on Firefox), since it is intentionally invalid code.
Another solution which works nicely at least on Firefox and Chromium is to temporarily make the <input>
element readOnly
, like this:
function handleScroll(e) {
if (e.target.tagName.toLowerCase() === 'input'
&& (e.target.type === 'number')
&& (e.target === document.activeElement)
&& !e.target.readOnly
) {
e.target.readOnly = true;
setTimeout(function(el){ el.readOnly = false; }, 0, e.target);
}
}
document.addEventListener('wheel', function(e){ handleScroll(e); });
One side effect that I've noticed is that it may cause the field to flicker for a split-second if you have different styling for readOnly
fields, but for my case at least, this doesn't seem to be an issue.
Similarly, (as explained in James' answer) instead of modifying the readOnly
property, you can blur()
the field and then focus()
it back, but again, depending on styles in use, some flickering might occur.
Alternatively, as mentioned in other comments here, you can just call preventDefault()
on the event instead. Assuming that you only handle wheel
events on number inputs which are in focus and under the mouse cursor (that's what the three conditions above signify), negative impact on user experience would be close to none.
Try this: Right click on your project -> Go to properties -> Click signing which is left side of the screen -> Uncheck the Sign the click once manifests -> Save & Build

Does Add to homescreen work on Chrome for iOS?
No.
The default value is indeed false.
However you can't use a local variable is it's not been assigned first.
You can use the default keyword to verify:
bool foo = default(bool);
if (!foo) { Console.WriteLine("Default is false"); }

In case, you would like to collect bitstamp trade data form their websocket in higher resolution over longer time period you could use script log_bitstamp_trades.py below.
The script uses python websocket-client and pusher_client_python libraries, so install them.

THE new @RestController annotation in Spring4+, which marks the class as a controller where every method returns a domain object instead of a view. It’s shorthand for @Controller and @ResponseBody rolled together.
You can make method which return the datatable of given sql query:
public DataTable GetDataTable()
{
SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["BarManConnectionString"].ConnectionString);
conn.Open();
string query = "SELECT * FROM [EventOne] ";
SqlCommand cmd = new SqlCommand(query, conn);
DataTable t1 = new DataTable();
using (SqlDataAdapter a = new SqlDataAdapter(cmd))
{
a.Fill(t1);
}
return t1;
}
and now can be used like this:
table = GetDataTable();
Here's the code for server side firebase cloud request from C# / Asp.net.
Please note that your client side should have same topic.
e.g.
FirebaseMessaging.getInstance().subscribeToTopic("news");
public String SendNotificationFromFirebaseCloud()
{
var result = "-1";
var webAddr = "https://fcm.googleapis.com/fcm/send";
var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
httpWebRequest.ContentType = "application/json";
httpWebRequest.Headers.Add("Authorization:key=" + YOUR_FIREBASE_SERVER_KEY);
httpWebRequest.Method = "POST";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = "{\"to\": \"/topics/news\",\"data\": {\"message\": \"This is a Firebase Cloud Messaging Topic Message!\",}}";
streamWriter.Write(json);
streamWriter.Flush();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
result = streamReader.ReadToEnd();
}
return result;
}
I found the answer. IE stores passwords in two different locations based on the password type:
%APPDATA%\Microsoft\Credentials
, in encrypted filesHKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2
, encrypted with the urlFrom a very good page on NirSoft.com:
Starting from version 7.0 of Internet Explorer, Microsoft completely changed the way that passwords are saved. In previous versions (4.0 - 6.0), all passwords were saved in a special location in the Registry known as the "Protected Storage". In version 7.0 of Internet Explorer, passwords are saved in different locations, depending on the type of password. Each type of passwords has some limitations in password recovery:
AutoComplete Passwords: These passwords are saved in the following location in the Registry:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2
The passwords are encrypted with the URL of the Web sites that asked for the passwords, and thus they can only be recovered if the URLs are stored in the history file. If you clear the history file, IE PassView won't be able to recover the passwords until you visit again the Web sites that asked for the passwords. Alternatively, you can add a list of URLs of Web sites that requires user name/password into the Web sites file (see below).HTTP Authentication Passwords: These passwords are stored in the Credentials file under
Documents and Settings\Application Data\Microsoft\Credentials
, together with login passwords of LAN computers and other passwords. Due to security limitations, IE PassView can recover these passwords only if you have administrator rights.
In my particular case it answers the question of where; and I decided that I don't want to duplicate that. I'll continue to use CredRead
/CredWrite
, where the user can manage their passwords from within an established UI system in Windows.
It would be easier using stringstreams:
#include <sstream>
int x = 42; // The integer
string str; // The string
ostringstream temp; // 'temp' as in temporary
temp << x;
str = temp.str(); // str is 'temp' as string
Or make a function:
#include <sstream>
string IntToString(int a)
{
ostringstream temp;
temp << a;
return temp.str();
}
You can actually chain multiple $lookup stages. Based on the names of the collections shared by profesor79, you can do this :
db.sivaUserInfo.aggregate([
{
$lookup: {
from: "sivaUserRole",
localField: "userId",
foreignField: "userId",
as: "userRole"
}
},
{
$unwind: "$userRole"
},
{
$lookup: {
from: "sivaUserInfo",
localField: "userId",
foreignField: "userId",
as: "userInfo"
}
},
{
$unwind: "$userInfo"
}
])
This will return the following structure :
{
"_id" : ObjectId("56d82612b63f1c31cf906003"),
"userId" : "AD",
"phone" : "0000000000",
"userRole" : {
"_id" : ObjectId("56d82612b63f1c31cf906003"),
"userId" : "AD",
"role" : "admin"
},
"userInfo" : {
"_id" : ObjectId("56d82612b63f1c31cf906003"),
"userId" : "AD",
"phone" : "0000000000"
}
}
Maybe this could be considered an anti-pattern because MongoDB wasn't meant to be relational but it is useful.
If you wish to create a pdf from php, pdflib will help you (as some others suggested).
Else, if you want to convert an HTML page to PDF via PHP, you'll find a little trouble outta here.. For 3 years I've been trying to do it as best as I can.
So, the options I know are:
DOMPDF : php class that wraps the html and builds the pdf. Works good, customizable (if you know php), based on pdflib, if I remember right it takes even some CSS. Bad news: slow when the html is big or complex.
HTML2PS: same as DOMPDF, but this one converts first to a .ps (ghostscript) file, then, to whatever format you need (pdf, jpg, png). For me is little better than dompdf, but has the same speed problem.. but, better compatibility with CSS.
Those two are php classes, but if you can install some software on the server, and access it throught passthru() or system(), give a look to these too:
wkhtmltopdf: based on webkit (safari's wrapper), is really fast and powerful.. seems like this is the best one (atm) for converting html pages to pdf on the fly; taking only 2 seconds for a 3 page xHTML document with CSS2. It is a recent project, anyway, the google.code page is often updated.
htmldoc : This one is a tank, it never really stops/crashes.. the project looks dead since 2007, but anyway if you don't need CSS compatibility this can be nice for you.
Say your table is called t1
and your primary-key is called id
First, create the sequence:
create sequence t1_seq start with 1 increment by 1 nomaxvalue;
Then create a trigger that increments upon insert:
create trigger t1_trigger
before insert on t1
for each row
begin
select t1_seq.nextval into :new.id from dual;
end;
You see the two empty -D
entries in the g++
command line? They're causing the problem. You must have values in the -D
items e.g. -DWIN32
if you're insistent on using something like -D$(SYSTEM) -D$(ENVIRONMENT) then you can use something like:
SYSTEM ?= generic
ENVIRONMENT ?= generic
in the makefile which gives them default values.
Your output looks to be missing the all important output:
<command-line>:0:1: error: macro names must be identifiers
<command-line>:0:1: error: macro names must be identifiers
just to clarify, what actually got sent to g++
was -D -DWindows_NT
, i.e. define a preprocessor macro called -DWindows_NT
; which is of course not a valid identifier (similarly for -D -I.
)
Simply make coffee
depend on clean
, and develop
depend on coffee
:
gulp.task('coffee', ['clean'], function(){...});
gulp.task('develop', ['coffee'], function(){...});
Dispatch is now serial: clean
→ coffee
→ develop
. Note that clean
's implementation and coffee
's implementation must accept a callback, "so the engine knows when it'll be done":
gulp.task('clean', function(callback){
del(['dist/*'], callback);
});
In conclusion, below is a simple gulp pattern for a synchronous clean
followed by asynchronous build dependencies:
//build sub-tasks
gulp.task('bar', ['clean'], function(){...});
gulp.task('foo', ['clean'], function(){...});
gulp.task('baz', ['clean'], function(){...});
...
//main build task
gulp.task('build', ['foo', 'baz', 'bar', ...], function(){...})
Gulp is smart enough to run clean
exactly once per build
, no matter how many of build
's dependencies depend on clean
. As written above, clean
is a synchronization barrier, then all of build
's dependencies run in parallel, then build
runs.
Really the format can be quite simple - sometimes there's no need to predefine a temp table - it will be created from results of the select.
Select FieldA...FieldN
into #MyTempTable
from MyTable
So unless you want different types or are very strict on definition, keep things simple. Note also that any temporary table created inside a stored procedure is automatically dropped when the stored procedure finishes executing. If stored procedure A creates a temp table and calls stored procedure B, then B will be able to use the temporary table that A created.
However, it's generally considered good coding practice to explicitly drop every temporary table you create anyway.
for some reason, my.demo.service has the same level as src/ in eclise project explorer view. After I move my.demo.service under src/, it is fine. Seems I should not create new package in "Project Explorer" view in Eclipse...
But thank you for your response:)
I had a ton of trouble with this and then found a great solution:
Create a file in a text editor called whoami.php with the below code as it's content, save the file and upload it to public_html (or whatever you root of your webserver directory is named). It should output a useful string that you can use to track down the user the webserver is running as, my output was "php is running as user: nt authority\iusr" which allowed me to track down the permissions I needed to modify to the user "IUSR".
<?php
// outputs the username that owns the running php/httpd process
// (on a system with the "whoami" executable in the path)
echo 'php is running as user: ' . exec('whoami');
?>
-ErrorAction Stop
is changing things for you. Try adding this and see what you get:
Catch [System.Management.Automation.ActionPreferenceStopException] {
"caught a StopExecution Exception"
$error[0]
}
While I know many architectures like ASP.NET MVC have built-in functionality to handle JSON.stringify as the contentType my situation is a little different so maybe this may help someone in the future. I know it would have saved me hours!
Since my http requests are being handled by a CGI API from IBM (AS400 environment) on a different subdomain these requests are cross origin, hence the jsonp. I actually send my ajax via javascript object(s). Here is an example of my ajax POST:
var data = {USER : localProfile,
INSTANCE : "HTHACKNEY",
PAGE : $('select[name="PAGE"]').val(),
TITLE : $("input[name='TITLE']").val(),
HTML : html,
STARTDATE : $("input[name='STARTDATE']").val(),
ENDDATE : $("input[name='ENDDATE']").val(),
ARCHIVE : $("input[name='ARCHIVE']").val(),
ACTIVE : $("input[name='ACTIVE']").val(),
URGENT : $("input[name='URGENT']").val(),
AUTHLST : authStr};
//console.log(data);
$.ajax({
type: "POST",
url: "http://www.domian.com/webservicepgm?callback=?",
data: data,
dataType:'jsonp'
}).
done(function(data){
//handle data.WHATEVER
});
I was looking forward this for a long time, and found no simple working example, but based on these answers I created the downloadAndUnzip()
function.
The usage is quite simple:
downloadAndUnzip('http://your-domain.com/archive.zip', 'yourfile.xml')
.then(function (data) {
console.log(data); // unzipped content of yourfile.xml in root of archive.zip
})
.catch(function (err) {
console.error(err);
});
And here is the declaration:
var AdmZip = require('adm-zip');
var request = require('request');
var downloadAndUnzip = function (url, fileName) {
/**
* Download a file
*
* @param url
*/
var download = function (url) {
return new Promise(function (resolve, reject) {
request({
url: url,
method: 'GET',
encoding: null
}, function (err, response, body) {
if (err) {
return reject(err);
}
resolve(body);
});
});
};
/**
* Unzip a Buffer
*
* @param buffer
* @returns {Promise}
*/
var unzip = function (buffer) {
return new Promise(function (resolve, reject) {
var resolved = false;
var zip = new AdmZip(buffer);
var zipEntries = zip.getEntries(); // an array of ZipEntry records
zipEntries.forEach(function (zipEntry) {
if (zipEntry.entryName == fileName) {
resolved = true;
resolve(zipEntry.getData().toString('utf8'));
}
});
if (!resolved) {
reject(new Error('No file found in archive: ' + fileName));
}
});
};
return download(url)
.then(unzip);
};
I think the answers are below
List<string> aa = (from char c in source
select c.ToString() ).ToList();
List<string> aa2 = (from char c1 in source
from char c2 in source
select string.Concat(c1, ".", c2)).ToList();

You can configure the output directory using the CONFIGURATION_BUILD_DIR
environment variable.
It is also possible to use enumeration.
typedef enum {
typeNo1 = 1,
typeNo2,
typeNo3,
typeNo4,
NumOfTypes = typeNo4
} TypeOfSomething;
What I believe you're looking for is a way to work with arrays as object values:
var o = {} // empty Object
var key = 'Orientation Sensor';
o[key] = []; // empty Array, which you can push() values into
var data = {
sampleTime: '1450632410296',
data: '76.36731:3.4651554:0.5665419'
};
var data2 = {
sampleTime: '1450632410296',
data: '78.15431:0.5247617:-0.20050584'
};
o[key].push(data);
o[key].push(data2);
This is standard JavaScript and not something NodeJS specific. In order to serialize it to a JSON string you can use the native JSON.stringify
:
JSON.stringify(o);
//> '{"Orientation Sensor":[{"sampleTime":"1450632410296","data":"76.36731:3.4651554:0.5665419"},{"sampleTime":"1450632410296","data":"78.15431:0.5247617:-0.20050584"}]}'
Change the checkboxes so that the name includes the index inside the brackets:
<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>">
The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.
This may be coming in Late but I think I figured out a better way to load external configurations especially when you run your spring-boot app using java jar myapp.war
instead of @PropertySource("classpath:some.properties")
The configuration would be loaded form the root of the project or from the location the war/jar file is being run from
public class Application implements EnvironmentAware {
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
@Override
public void setEnvironment(Environment environment) {
//Set up Relative path of Configuration directory/folder, should be at the root of the project or the same folder where the jar/war is placed or being run from
String configFolder = "config";
//All static property file names here
List<String> propertyFiles = Arrays.asList("application.properties","server.properties");
//This is also useful for appending the profile names
Arrays.asList(environment.getActiveProfiles()).stream().forEach(environmentName -> propertyFiles.add(String.format("application-%s.properties", environmentName)));
for (String configFileName : propertyFiles) {
File configFile = new File(configFolder, configFileName);
LOGGER.info("\n\n\n\n");
LOGGER.info(String.format("looking for configuration %s from %s", configFileName, configFolder));
FileSystemResource springResource = new FileSystemResource(configFile);
LOGGER.log(Level.INFO, "Config file : {0}", (configFile.exists() ? "FOund" : "Not Found"));
if (configFile.exists()) {
try {
LOGGER.info(String.format("Loading configuration file %s", configFileName));
PropertiesFactoryBean pfb = new PropertiesFactoryBean();
pfb.setFileEncoding("UTF-8");
pfb.setLocation(springResource);

The best practice to connect to mongoDB as follow:
After initial installation,
use admin
Then run the following script to create admin user
db.createUser(
{
user: "YourUserName",
pwd: "YourPassword",
roles: [
{ role: "userAdminAnyDatabase", db: "admin" },
{ role: "readWriteAnyDatabase", db: "admin" },
{ role: "dbAdminAnyDatabase", db: "admin" },
{ role: "clusterAdmin", db: "admin" }
]
})
the following script will create the admin user for the DB.
log into the db.admin
using
mongo -u YourUserName -p YourPassword admin
After login, you can create N number of the database with same admin credential or different by repeating the 1 to 3.
This allows you to create different user and password for the different collection you creating in the MongoDB
Go to wherever you installed Android Studio (for me it's under C:\Users\username\AppData\Local\Android\android-studio\
) and open sdk\tools
, then run android.bat
. From here, update and download any missing build-tools and make sure you update the Android Support Repository and Android Support Library under Extras. Restart Android Studio after the SDK Manager finishes.
It seems that Android Studio completely ignores any installed Android SDK files and keeps a copy of its own. After running an update, everything compiled successfully for me using compile com.android.support:appcompat-v7:18.0.+
For me the issue was about a comma not in the filename but as below: -
Response.ok(streamingOutput,MediaType.APPLICATION_OCTET_STREAM_TYPE).header("content-disposition", "attachment, filename=your_file_name").build();
I accidentally put a comma after attachment. Got it resolved by replacing comma with a semicolon.
Very rarely.

There is also a bug to implement this in Chrome.
Beware that this property is only supported by Firefox and is likely to be deprecated.

The CosisEntities
class is your DbContext
. When you create a context in a using
block, you're defining the boundaries for your data-oriented operation.
In your code, you're trying to emit the result of a query from a method and then end the context within the method. The operation you pass the result to then tries to access the entities in order to populate the grid view. Somewhere in the process of binding to the grid, a lazy-loaded property is being accessed and Entity Framework is trying to perform a lookup to obtain the values. It fails, because the associated context has already ended.
You have two problems:
You're lazy-loading entities when you bind to the grid. This means that you're doing lots of separate query operations to SQL Server, which are going to slow everything down. You can fix this issue by either making the related properties eager-loaded by default, or asking Entity Framework to include them in the results of this query by using the Include
extension method.
You're ending your context prematurely: a DbContext
should be available throughout the unit of work being performed, only disposing it when you're done with the work at hand. In the case of ASP.NET, a unit of work is typically the HTTP request being handled.
This should work fine for you.

Mockito matchers are static methods and calls to those methods, which stand in for arguments during calls to when
and verify
.
Hamcrest matchers (archived version) (or Hamcrest-style matchers) are stateless, general-purpose object instances that implement Matcher<T>
and expose a method matches(T)
that returns true if the object matches the Matcher's criteria. They are intended to be free of side effects, and are generally used in assertions such as the one below.
/* Mockito */ verify(foo).setPowerLevel(gt(9000));
/* Hamcrest */ assertThat(foo.getPowerLevel(), is(greaterThan(9000)));
Mockito matchers exist, separate from Hamcrest-style matchers, so that descriptions of matching expressions fit directly into method invocations: Mockito matchers return T
where Hamcrest matcher methods return Matcher objects (of type Matcher<T>
).
Mockito matchers are invoked through static methods such as eq
, any
, gt
, and startsWith
on org.mockito.Matchers
and org.mockito.AdditionalMatchers
. There are also adapters, which have changed across Mockito versions:
Matchers
featured some calls (such as intThat
or argThat
) are Mockito matchers that directly accept Hamcrest matchers as parameters. ArgumentMatcher<T>
extended org.hamcrest.Matcher<T>
, which was used in the internal Hamcrest representation and was a Hamcrest matcher base class instead of any sort of Mockito matcher.Matchers
calls phrased as intThat
or argThat
wrap ArgumentMatcher<T>
objects that no longer implement org.hamcrest.Matcher<T>
but are used in similar ways. Hamcrest adapters such as argThat
and intThat
are still available, but have moved to MockitoHamcrest
instead.Regardless of whether the matchers are Hamcrest or simply Hamcrest-style, they can be adapted like so:
/* Mockito matcher intThat adapting Hamcrest-style matcher is(greaterThan(...)) */
verify(foo).setPowerLevel(intThat(is(greaterThan(9000))));
In the above statement: foo.setPowerLevel
is a method that accepts an int
. is(greaterThan(9000))
returns a Matcher<Integer>
, which wouldn't work as a setPowerLevel
argument. The Mockito matcher intThat
wraps that Hamcrest-style Matcher and returns an int
so it can appear as an argument; Mockito matchers like gt(9000)
would wrap that entire expression into a single call, as in the first line of example code.
when(foo.quux(3, 5)).thenReturn(true);
When not using argument matchers, Mockito records your argument values and compares them with their equals
methods.
when(foo.quux(eq(3), eq(5))).thenReturn(true); // same as above
when(foo.quux(anyInt(), gt(5))).thenReturn(true); // this one's different
When you call a matcher like any
or gt
(greater than), Mockito stores a matcher object that causes Mockito to skip that equality check and apply your match of choice. In the case of argumentCaptor.capture()
it stores a matcher that saves its argument instead for later inspection.
Matchers return dummy values such as zero, empty collections, or null
. Mockito tries to return a safe, appropriate dummy value, like 0 for anyInt()
or any(Integer.class)
or an empty List<String>
for anyListOf(String.class)
. Because of type erasure, though, Mockito lacks type information to return any value but null
for any()
or argThat(...)
, which can cause a NullPointerException if trying to "auto-unbox" a null
primitive value.
Matchers like eq
and gt
take parameter values; ideally, these values should be computed before the stubbing/verification starts. Calling a mock in the middle of mocking another call can interfere with stubbing.
Matcher methods can't be used as return values; there is no way to phrase thenReturn(anyInt())
or thenReturn(any(Foo.class))
in Mockito, for instance. Mockito needs to know exactly which instance to return in stubbing calls, and will not choose an arbitrary return value for you.
Matchers are stored (as Hamcrest-style object matchers) in a stack contained in a class called ArgumentMatcherStorage. MockitoCore and Matchers each own a ThreadSafeMockingProgress instance, which statically contains a ThreadLocal holding MockingProgress instances. It's this MockingProgressImpl that holds a concrete ArgumentMatcherStorageImpl. Consequently, mock and matcher state is static but thread-scoped consistently between the Mockito and Matchers classes.
Most matcher calls only add to this stack, with an exception for matchers like and
, or
, and not
. This perfectly corresponds to (and relies on) the evaluation order of Java, which evaluates arguments left-to-right before invoking a method:
when(foo.quux(anyInt(), and(gt(10), lt(20)))).thenReturn(true);
[6] [5] [1] [4] [2] [3]
This will:
anyInt()
to the stack.gt(10)
to the stack.lt(20)
to the stack.gt(10)
and lt(20)
and add and(gt(10), lt(20))
.foo.quux(0, 0)
, which (unless otherwise stubbed) returns the default value false
. Internally Mockito marks quux(int, int)
as the most recent call.when(false)
, which discards its argument and prepares to stub method quux(int, int)
identified in 5. The only two valid states are with stack length 0 (equality) or 2 (matchers), and there are two matchers on the stack (steps 1 and 4), so Mockito stubs the method with an any()
matcher for its first argument and and(gt(10), lt(20))
for its second argument and clears the stack.This demonstrates a few rules:
Mockito can't tell the difference between quux(anyInt(), 0)
and quux(0, anyInt())
. They both look like a call to quux(0, 0)
with one int matcher on the stack. Consequently, if you use one matcher, you have to match all arguments.
Call order isn't just important, it's what makes this all work. Extracting matchers to variables generally doesn't work, because it usually changes the call order. Extracting matchers to methods, however, works great.
int between10And20 = and(gt(10), lt(20));
/* BAD */ when(foo.quux(anyInt(), between10And20)).thenReturn(true);
// Mockito sees the stack as the opposite: and(gt(10), lt(20)), anyInt().
public static int anyIntBetween10And20() { return and(gt(10), lt(20)); }
/* OK */ when(foo.quux(anyInt(), anyIntBetween10And20())).thenReturn(true);
// The helper method calls the matcher methods in the right order.
The stack changes often enough that Mockito can't police it very carefully. It can only check the stack when you interact with Mockito or a mock, and has to accept matchers without knowing whether they're used immediately or abandoned accidentally. In theory, the stack should always be empty outside of a call to when
or verify
, but Mockito can't check that automatically.
You can check manually with Mockito.validateMockitoUsage()
.
In a call to when
, Mockito actually calls the method in question, which will throw an exception if you've stubbed the method to throw an exception (or require non-zero or non-null values).
doReturn
and doAnswer
(etc) do not invoke the actual method and are often a useful alternative.
If you had called a mock method in the middle of stubbing (e.g. to calculate an answer for an eq
matcher), Mockito would check the stack length against that call instead, and likely fail.
If you try to do something bad, like stubbing/verifying a final method, Mockito will call the real method and also leave extra matchers on the stack. The final
method call may not throw an exception, but you may get an InvalidUseOfMatchersException from the stray matchers when you next interact with a mock.
InvalidUseOfMatchersException:
Check that every single argument has exactly one matcher call, if you use matchers at all, and that you haven't used a matcher outside of a when
or verify
call. Matchers should never be used as stubbed return values or fields/variables.
Check that you're not calling a mock as a part of providing a matcher argument.
Check that you're not trying to stub/verify a final method with a matcher. It's a great way to leave a matcher on the stack, and unless your final method throws an exception, this might be the only time you realize the method you're mocking is final.
NullPointerException with primitive arguments: (Integer) any()
returns null while any(Integer.class)
returns 0; this can cause a NullPointerException
if you're expecting an int
instead of an Integer. In any case, prefer anyInt()
, which will return zero and also skip the auto-boxing step.
NullPointerException or other exceptions: Calls to when(foo.bar(any())).thenReturn(baz)
will actually call foo.bar(null)
, which you might have stubbed to throw an exception when receiving a null argument. Switching to doReturn(baz).when(foo).bar(any())
skips the stubbed behavior.
Use MockitoJUnitRunner, or explicitly call validateMockitoUsage
in your tearDown
or @After
method (which the runner would do for you automatically). This will help determine whether you've misused matchers.
For debugging purposes, add calls to validateMockitoUsage
in your code directly. This will throw if you have anything on the stack, which is a good warning of a bad symptom.
I solve this in my VB app with a simple tiny function (one line). Code taken out of a production app. The function looks like this:
Public Function MySQLDateTimeVar(inDate As Date, inTime As String) As String Return "'" & inDate.ToString(format:="yyyy'-'MM'-'dd") & " " & inTime & "'" End Function
Usage: Let's say I have DateTimePicker1 and DateTimePicker2 and the user must define a start date and an end date. No matter if the dates are the same. I need to query a DATETIME field using only the DATE. My query string is easily built like this:
Dim QueryString As String = "Select * From SOMETABLE Where SOMEDATETIMEFIELD BETWEEN " & MySQLDateTimeVar(DateTimePicker1.Value,"00:00:00") & " AND " & MySQLDateTimeVar(DateTimePicker2.Value,"23:59:59")
The function generates the correct MySQL DATETIME syntax for DATETIME fields in the query and the query returns all records on that DATE (or BETWEEN the DATES) correctly.
I noticed there are some differences in how the app name can turn up in Lollipop devices. Before Lollipop, you can have different app names with this:
<application
android:label="@string/app_name"> // appears in manage app info
<activity
android:name=".MainActivity"
android:label="@string/action_bar_title"> // appears in actionbar title
<intent-filter android:label="@string/name_in_icon_launcher"> // appears in icon launcher
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
...
In Lollipop, it will be like this:
<application
android:label="@string/name_in_manage_app_info">
<activity
android:name=".MainActivity"
android:label="@string/name_in_actionbar_and_icon_launcher">
<intent-filter android:label="@string/this_is_useless">
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
In Lollipop, android:label
in intent-filter is basically useless, while actionbar title and icon launcher is identical. So, if you want a different title in actionbar, you have no choice but to set dynamically
getSupportActionBar().setTitle(R.string.app_name);
Please check the sample code for the Google Maps Android API v2. Using this will solve your problem.
private void setUpMapIfNeeded() {
// Do a null check to confirm that we have not already instantiated the map.
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
mMap.setMyLocationEnabled(true);
// Check if we were successful in obtaining the map.
if (mMap != null) {
mMap.setOnMyLocationChangeListener(new GoogleMap.OnMyLocationChangeListener() {
@Override
public void onMyLocationChange(Location arg0) {
mMap.addMarker(new MarkerOptions().position(new LatLng(arg0.getLatitude(), arg0.getLongitude())).title("It's Me!"));
}
});
}
}
}

You can use CSS3 transitions or maybe CSS3 animations to slide in an element.
For browser support: http://caniuse.com/
I made two quick examples just to show you how I mean.
CSS transition (on hover)
Relevant Code
.wrapper:hover #slide {
transition: 1s;
left: 0;
}
In this case, Im just transitioning the position from left: -100px;
to 0;
with a 1s. duration. It's also possible to move the element using transform: translate();
CSS animation
#slide {
position: absolute;
left: -100px;
width: 100px;
height: 100px;
background: blue;
-webkit-animation: slide 0.5s forwards;
-webkit-animation-delay: 2s;
animation: slide 0.5s forwards;
animation-delay: 2s;
}
@-webkit-keyframes slide {
100% { left: 0; }
}
@keyframes slide {
100% { left: 0; }
}
Same principle as above (Demo One), but the animation starts automatically after 2s, and in this case I've set animation-fill-mode
to forwards
, which will persist the end state, keeping the div visible when the animation ends.
Like I said, two quick example to show you how it could be done.

With the plugin: jQuery Selection Box. You can do this:
var myOptions = {
"Value 1" : "Text 1",
"Value 2" : "Text 2",
"Value 3" : "Text 3"
}
$("#myselect2").addOption(myOptions, false);
Though classmethod
and staticmethod
are quite similar, there's a slight difference in usage for both entities: classmethod
must have a reference to a class object as the first parameter, whereas staticmethod
can have no parameters at all.
class Date(object):
def __init__(self, day=0, month=0, year=0):
self.day = day
self.month = month
self.year = year
@classmethod
def from_string(cls, date_as_string):
day, month, year = map(int, date_as_string.split('-'))
date1 = cls(day, month, year)
return date1
@staticmethod
def is_date_valid(date_as_string):
day, month, year = map(int, date_as_string.split('-'))
return day <= 31 and month <= 12 and year <= 3999
date2 = Date.from_string('11-09-2012')
is_date = Date.is_date_valid('11-09-2012')
Let's assume an example of a class, dealing with date information (this will be our boilerplate):
class Date(object):
def __init__(self, day=0, month=0, year=0):
self.day = day
self.month = month
self.year = year
This class obviously could be used to store information about certain dates (without timezone information; let's assume all dates are presented in UTC).
Here we have __init__
, a typical initializer of Python class instances, which receives arguments as a typical instancemethod
, having the first non-optional argument (self
) that holds a reference to a newly created instance.
Class Method
We have some tasks that can be nicely done using classmethod
s.
Let's assume that we want to create a lot of Date
class instances having date information coming from an outer source encoded as a string with format 'dd-mm-yyyy'. Suppose we have to do this in different places in the source code of our project.
So what we must do here is:
Date
by passing those values to the initialization call.This will look like:
day, month, year = map(int, string_date.split('-'))
date1 = Date(day, month, year)
For this purpose, C++ can implement such a feature with overloading, but Python lacks this overloading. Instead, we can use classmethod
. Let's create another "constructor".
@classmethod
def from_string(cls, date_as_string):
day, month, year = map(int, date_as_string.split('-'))
date1 = cls(day, month, year)
return date1
date2 = Date.from_string('11-09-2012')
Let's look more carefully at the above implementation, and review what advantages we have here:
cls
is an object that holds the class itself, not an instance of the class. It's pretty cool because if we inherit our Date
class, all children will have from_string
defined also.Static method
What about staticmethod
? It's pretty similar to classmethod
but doesn't take any obligatory parameters (like a class method or instance method does).
Let's look at the next use case.
We have a date string that we want to validate somehow. This task is also logically bound to the Date
class we've used so far, but doesn't require instantiation of it.
Here is where staticmethod
can be useful. Let's look at the next piece of code:
@staticmethod
def is_date_valid(date_as_string):
day, month, year = map(int, date_as_string.split('-'))
return day <= 31 and month <= 12 and year <= 3999
# usage:
is_date = Date.is_date_valid('11-09-2012')
So, as we can see from usage of staticmethod
, we don't have any access to what the class is---it's basically just a function, called syntactically like a method, but without access to the object and its internals (fields and another methods), while classmethod does.
boost::ptr_vector<int>
will work.
Edit: was a suggestion to use std::vector< boost::ref<int> >
, which will not work because you can't default-construct a boost::ref
.

In order to best standardise your @font-face embedded fonts across browsers try including the below inside your @font-face declaration or on your body font styling:
speak: none;
font-style: normal;
font-weight: normal;
font-variant: normal;
text-transform: none;
line-height: 1;
-webkit-font-smoothing: antialiased;
At present there looks to be no universal fix across all platforms and browser builds. As stated frequently all browsers/OS have different text rendering engines.
