A for each loop structure is more designed around the collection object. A For..Each loop requires a variant type or object. Since your "element" variable is being typed as a variant your "do_something" function will need to accept a variant type, or you can modify your loop to something like this:
Public Sub Example()
Dim sArray(4) As String
Dim i As Long
For i = LBound(sArray) To UBound(sArray)
do_something sArray(i)
Next i
End Sub
Just echo the javascript out inside the if function
<form name="testForm" id="testForm" method="POST" >
<input type="submit" name="btn" value="submit" autofocus onclick="return true;"/>
</form>
<?php
if(isset($_POST['btn'])){
echo "
<script type=\"text/javascript\">
var e = document.getElementById('testForm'); e.action='test.php'; e.submit();
</script>
";
}
?>
Instead of create the new Container class you can use a dataTable.
DataTable dt = new DataTable();
dt.Columns.Add("My first column Name");
dt.Rows.Add(new object[] { "Item 1" });
dt.Rows.Add(new object[] { "Item number 2" });
dt.Rows.Add(new object[] { "Item number three" });
myDataGridView.DataSource = dt;

I also tried deleting the database again, called update-database and then add-migration. I ended up with an additional migration that seems not to change anything (see below)
Based on above details, I think you have done last thing first. If you run Update database
before Add-migration
, it won't update the database with your migration schemas. First you need to add the migration and then run update command.
Try them in this order using package manager console.
PM> Enable-migrations //You don't need this as you have already done it
PM> Add-migration Give_it_a_name
PM> Update-database
In one line ... Removes all classes that match a regular expression someRegExp
$('#my_element_id').removeClass( function() { return (this.className.match(/someRegExp/g) || []).join(' ').replace(prog.status.toLowerCase(),'');});
You'll have to wait. The session that was killed was in the middle of a transaction and updated lots of records. These records have to be rollbacked and some background process is taking care of that. In the meantime you cannot modify the records that were touched.
Try this module: http://pypi.python.org/pypi/interruptingcow/
from interruptingcow import timeout
try:
with timeout(60*5, exception=RuntimeError):
while True:
test = 0
if test == 5:
break
test = test - 1
except RuntimeError:
pass
A little late, but here's my fool proof solution useful for pages like the sign up/registration page where the user has to input a new password.
<form method="post">
<input type="text" name="fname" id="firstname" x-autocompletetype="given-name" autocomplete="on">
<input type="text" name="lname" id="lastname" x-autocompletetype="family-name" autocomplete="on">
<input type="text" name="email" id="email" x-autocompletetype="email" autocomplete="on">
<input type="password" name="password" id="password_fake" class="hidden" autocomplete="off" style="display: none;">
<input type="password" name="password" id="password" autocomplete="off">
</form>
Chrome will detect two password inputs and will not auto fill the password fields. However, the field id="password_fake" one will be hidden via CSS. So the user will only see one password field.
I've also added some extra attributes "x-autocompletetype" which is a chrome experimental specific auto fill feature. From my example, chrome will autofill in the first name, last name and email address, and NOT the password field.
As per this question's answer
You will want something like this:
<bindings> <basicHttpBinding> <binding name="basicHttp" allowCookies="true" maxReceivedMessageSize="20000000" maxBufferSize="20000000" maxBufferPoolSize="20000000"> <readerQuotas maxDepth="32" maxArrayLength="200000000" maxStringContentLength="200000000"/> </binding> </basicHttpBinding> </bindings>

Firstly, if the users of your API aren't interested in specific, fine-grained failures, then having specific exceptions for them isn't of any value.
Since it's often not possible to know what may be useful to your users, a better approach is to have the specific exceptions, but ensure they inherit from a common class (e.g., std::exception or its derivatives in C++). That allows your client to catch specific exceptions if they choose, or the more general exception if they don't care.
Actually, on 32-bit computers a word is 32-bit, but the DWORD type is a leftover from the good old days of 16-bit.
In order to make it easier to port programs to the newer system, Microsoft has decided all the old types will not change size.
You can find the official list here: http://msdn.microsoft.com/en-us/library/aa383751(VS.85).aspx
All the platform-dependent types that changed with the transition from 32-bit to 64-bit end with _PTR (DWORD_PTR will be 32-bit on 32-bit Windows and 64-bit on 64-bit Windows).
It's better to move all logic of working with database to repositores.
So in controller you write
/* you can also inject "FooRepository $repository" using autowire */
$repository = $this->getDoctrine()->getRepository(Foo::class);
$count = $repository->count();
And in Repository/FooRepository.php
public function count()
{
$qb = $repository->createQueryBuilder('t');
return $qb
->select('count(t.id)')
->getQuery()
->getSingleScalarResult();
}
It's better to move $qb = ...
to separate row in case you want to make complex expressions like
public function count()
{
$qb = $repository->createQueryBuilder('t');
return $qb
->select('count(t.id)')
->where($qb->expr()->isNotNull('t.fieldName'))
->andWhere($qb->expr()->orX(
$qb->expr()->in('t.fieldName2', 0),
$qb->expr()->isNull('t.fieldName2')
))
->getQuery()
->getSingleScalarResult();
}
Also think about caching your query result - http://symfony.com/doc/current/reference/configuration/doctrine.html#caching-drivers
public function count()
{
$qb = $repository->createQueryBuilder('t');
return $qb
->select('count(t.id)')
->getQuery()
->useQueryCache(true)
->useResultCache(true, 3600)
->getSingleScalarResult();
}
In some simple cases using EXTRA_LAZY
entity relations is good

It may not exactly fall into the 'grep' category, but I couldn't get by on Windows without a utility called AgentRansack. It's a gui-based "find in files" utility with regex support. It's dead simple to right-click on a folder, hit "ransack.." and find files containing what you're looking for. Extremely fast too.
While hash(frozenset(x.items())
and hash(tuple(sorted(x.items()))
work, that's doing a lot of work allocating and copying all the key-value pairs. A hash function really should avoid a lot of memory allocation.
A little bit of math can help here. The problem with most hash functions is that they assume that order matters. To hash an unordered structure, you need a commutative operation. Multiplication doesn't work well as any element hashing to 0 means the whole product is 0. Bitwise &
and |
tend towards all 0's or 1's. There are two good candidates: addition and xor.
from functools import reduce
from operator import xor
class hashable(dict):
def __hash__(self):
return reduce(xor, map(hash, self.items()), 0)
# Alternative
def __hash__(self):
return sum(map(hash, self.items()))
One point: xor works, in part, because dict
guarantees keys are unique. And sum works because Python will bitwise truncate the results.
If you want to hash a multiset, sum is preferable. With xor, {a}
would hash to the same value as {a, a, a}
because x ^ x ^ x = x
.
If you really need the guarantees that SHA makes, this won't work for you. But to use a dictionary in a set, this will work fine; Python containers are resiliant to some collisions, and the underlying hash functions are pretty good.
Follow these two simple steps and get increase height of your UItextField
.
Step 1: right click on XIB file and open it as in "Source Code".
Step 2: Find the same UITextfield
source and set the frame as you want.
You can use these steps to change frame of any apple controls.
Use a NavigableMap
implementation, like TreeMap
.
/* Setup */
NavigableMap<Integer, Optional<String>> messages = new TreeMap<>();
messages.put(Integer.MIN_VALUE, Optional.empty());
messages.put(1, Optional.of("testing case 1 to 5"));
messages.put(6, Optional.of("testing case 6 to 10"));
messages.put(11, Optional.empty());
/* Use */
messages.floorEntry(3).getValue().ifPresent(System.out::println);
Working with dplyr
library(dplyr)
df <- data.frame(A = factor(LETTERS[1:5]),
B = 1:5, C = as.logical(c(1, 1, 0, 0, 1)),
D = letters[1:5],
E = paste(LETTERS[1:5], letters[1:5]),
stringsAsFactors = FALSE)
str(df)
we get:
'data.frame': 5 obs. of 5 variables:
$ A: Factor w/ 5 levels "A","B","C","D",..: 1 2 3 4 5
$ B: int 1 2 3 4 5
$ C: logi TRUE TRUE FALSE FALSE TRUE
$ D: chr "a" "b" "c" "d" ...
$ E: chr "A a" "B b" "C c" "D d" ...
Now, we can convert all chr
to factors
:
df <- df%>%mutate_if(is.character, as.factor)
str(df)
And we get:
'data.frame': 5 obs. of 5 variables:
$ A: Factor w/ 5 levels "A","B","C","D",..: 1 2 3 4 5
$ B: int 1 2 3 4 5
$ C: logi TRUE TRUE FALSE FALSE TRUE
$ D: chr "a" "b" "c" "d" ...
$ E: chr "A a" "B b" "C c" "D d" ...
Let's provide also other solutions:
With base package:
df[sapply(df, is.character)] <- lapply(df[sapply(df, is.character)],
as.factor)
With dplyr
1.0.0
df <- df%>%mutate(across(where(is.factor), as.character))
With purrr
package:
library(purrr)
df <- df%>% modify_if(is.factor, as.character)
First, convert the timestamp using the built-in eloquent functionality, as described in this answer.
Then you can just use Carbon's min()
or max()
function for comparison. For example:
$dt1 = Carbon::create(2012, 1, 1, 0, 0, 0);
$dt2 = Carbon::create(2014, 1, 30, 0, 0, 0);
echo $dt1->min($dt2);
This will echo
the lesser of the two dates, which in this case is $dt1
.
You're right that the SD Card directory is /sdcard
but you shouldn't be hard coding it. Instead, make a call to Environment.getExternalStorageDirectory()
to get the directory:
File sdDir = Environment.getExternalStorageDirectory();
If you haven't done so already, you will need to give your app the correct permission to write to the SD Card by adding the line below to your Manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
In my case, I had all of the required features, but I had installed the Team Explorer version (accidentally used the wrong installer) before installing Professional.
When running the Team Explorer version, only the Blank Solution option was available.
The Team Explorer EXE was located in: "C:\Program Files (x86)\Microsoft Visual Studio\2017\TeamExplorer\Common7\IDE\devenv.exe"
Once I launched the correct EXE, Visual Studio started working as expected.
The Professional EXE was located in: "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\devenv.exe"
This solved my issue, and the reason was I had enterprise edition previously installed and then uninstalled and installed the professional edition. Team Explorer was not modified later when I moved to professional from enterprise edition.
May be by:-
for(Row row : sheet) {
for(Cell cell : row) {
System.out.print(cell.getStringCellValue());
}
}
For specific type of cell you can try:
switch (cell.getCellType()) {
case Cell.CELL_TYPE_STRING:
cellValue = cell.getStringCellValue();
break;
case Cell.CELL_TYPE_FORMULA:
cellValue = cell.getCellFormula();
break;
case Cell.CELL_TYPE_NUMERIC:
if (DateUtil.isCellDateFormatted(cell)) {
cellValue = cell.getDateCellValue().toString();
} else {
cellValue = Double.toString(cell.getNumericCellValue());
}
break;
case Cell.CELL_TYPE_BLANK:
cellValue = "";
break;
case Cell.CELL_TYPE_BOOLEAN:
cellValue = Boolean.toString(cell.getBooleanCellValue());
break;
}
There's no error here. You're printing a function, and that's what functions look like.
To actually call the function, you have to put parens after that. You're already doing that above. If you want to print the result of calling the function, just have the function return the value, and put the print there. For example:
print test.sort_word_list()
On the other hand, if you want the function to mutate the object's state, and then print the state some other way, that's fine too.
Now, your code seems to work in some places, but not others; let's look at why:
parser
sets a variable called word_list
, and you later print test.word_list
, so that works.sort_word_list
sets a variable called sorted_word_list
, and you later print test.sort_word_list
—that is, the function, not the variable. So, you see the bound method. (Also, as Jon Clements points out, even if you fix this, you're going to print None
, because that's what sort
returns.)num_words
sets a variable called num_words
, and you again print the function—but in this case, the variable has the same name as the function, meaning that you're actually replacing the function with its output, so it works. This is probably not what you want to do, however.(There are cases where, at first glance, that seems like it might be a good idea—you only want to compute something once, and then access it over and over again without constantly recomputing that. But this isn't the way to do it. Either use a @property
, or use a memoization decorator.)
change the file_path
to your file
import hashlib
def getMd5(file_path):
m = hashlib.md5()
with open(file_path,'rb') as f:
line = f.read()
m.update(line)
md5code = m.hexdigest()
return md5code
This happened to me. For some reason my origin got messed up without my realizing it:
Check if your settings are still correct
git remote -v
the url needs to be something like ssh://[email protected]/YourDirectory/YourProject.git; if you don't see [email protected], use
git remote set-url origin git://github.com/YourDirectory/YourProject.git
to set it right. Or you could use the github app to check and set the Primary Remote Repository url in the settings panel of your particular repository.
If you want to update your project using SVN then first of all:
Go to the path on which your project is stored through command prompt.
Use the command SVN update
That's it.
There is a very nice PHP library for detecting mobile clients here: http://mobiledetect.net
Using that it's quite easy to only display content for a mobile:
include 'Mobile_Detect.php';
$detect = new Mobile_Detect();
// Check for any mobile device.
if ($detect->isMobile()){
// mobile content
}
else {
// other content for desktops
}
Change http to https of the marked error or all the URL ending with *.xsd extension.
setLoanItem is an instance method, meaning you need an instance of the Media class in order to call it. You're attempting to call it on the Media type itself.
You may want to look into some basic object-oriented tutorials to see how static/instance members work.
Just use
for i in range(0, 5):
print i
to iterate through your data set and print each value.
For large data sets, you want to use xrange, which has a very similar signature, but works more effectively for larger data sets. http://docs.python.org/library/functions.html#xrange
On a single line...
pgrep -f process_name | xargs kill -9
If you mean using a literal, you simply have to create a binary string:
insert into Files (FileId, FileData) values (1, 0x010203040506)
And you will have a record with a six byte value for the FileData field.
You indicate in the comments that you want to just specify the file name, which you can't do with SQL Server 2000 (or any other version that I am aware of).
You would need a CLR stored procedure to do this in SQL Server 2005/2008 or an extended stored procedure (but I'd avoid that at all costs unless you have to) which takes the filename and then inserts the data (or returns the byte string, but that can possibly be quite long).
In regards to the question of only being able to get data from a SP/query, I would say the answer is yes, because if you give SQL Server the ability to read files from the file system, what do you do when you aren't connected through Windows Authentication, what user is used to determine the rights? If you are running the service as an admin (God forbid) then you can have an elevation of rights which shouldn't be allowed.
From the stack trace it's clear that, the ThreadPoolExecutor > Worker thread started and it's waiting for the task to be available on the BlockingQueue(DelayedWorkQueue) to pick the task and execute.So this thread will be in WAIT status only as long as get a SIGNAL from the publisher thread.
For me it works if I add this line below in .vcxproj
in the itemGroup
cpp file, which is connected to the header file.
<ClCompile Include="file.cpp" />

— they are the exact same thing. It's likely your editor is simply inserting the numberic reference instead of the named one.
See the Wikipedia page for the non-breaking space.
When you stop building a project when the compiler is in the middle of something "important", this error could appear. In that case, building the project again and letting it finish normally makes this error disappear.
Set the dimensions to the View and make sure your Image is styled with height and width set to 'undefined' like the example below :
<View style={{width: 10, height:10 }} >
<Image style= {{flex:1 , width: undefined, height: undefined}}
source={require('../yourfolder/yourimage')}
/>
</View>
This will make sure your image scales and fits perfectly into your view.
You had the identity
node as a child of authentication
node. That was the issue. As in the example above, authentication

You can create a non-nullable DATETIME column on your table, and create a DEFAULT constraint on it to auto populate when a row is added.
e.g.

)
If you want to change just on one page, add the following style rule:

Download Gradle as described above, but make sure you download version 1.9 and not the current release (1.11). I just had the same problem and downloaded the current release only to have Android Studio tell me it wasn't supported.
Besides setting iOS Deployment Target to iOS 8.0, also restart your iOS8 iPhone/iPad. This did the trick for me.
If your xml is written by java.lang.String
you can just using HttpClient
in this way
public void post() throws Exception{
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://www.baidu.com");
String xml = "<xml>xxxx</xml>";
HttpEntity entity = new ByteArrayEntity(xml.getBytes("UTF-8"));
post.setEntity(entity);
HttpResponse response = client.execute(post);
String result = EntityUtils.toString(response.getEntity());
}
pay attention to the Exceptions.
BTW, the example is written by the httpclient version 4.x
CTRL+F5 Reloads the current page, ignoring cached content and generating the expected result.
grep provides '-v' or '--invert-match' option to select non-matching lines.
e.g.
grep -v 'unwanted_pattern' file_name
This will output all the lines from file file_name, which does not have 'unwanted_pattern'.
If you are searching the pattern in multiple files inside a folder, you can use the recursive search option as follows
grep -r 'wanted_pattern' * | grep -v 'unwanted_pattern'
Here grep will try to list all the occurrences of 'wanted_pattern' in all the files from within currently directory and pass it to second grep to filter out the 'unwanted_pattern'. '|' - pipe will tell shell to connect the standard output of left program (grep -r 'wanted_pattern' *) to standard input of right program (grep -v 'unwanted_pattern').
There is another route of failure, besides the version of Java you are running: You could be running out of Heap/RAM
If you had a once working version of SQLDeveloper, and you are starting to see the screenshot referenced in the original post, then you can try to adjust the amount of space SQLDeveloper requests when starting up.
Edit the file:
/ide/bin/ide.conf
Edit the line that specifies the max ram to use: AddVMOption -Xmx, reducing the size. For example I changed my file to have the following lines, which solved the issue.
#AddVMOption -Xmx640M # Original Value
AddVMOption -Xmx256M # New Value
A hack the I've used on Solaris 9 and Linux and which works fine for both of them:
ps -o user= -p $$ | awk '{print $1}'
This snippet prints the name of the user with the current EUID.
NOTE: you need Bash as the interpreter here.
On Solaris you have problems with methods, described above:
id
does not accept the -u
and -n
parameters (so you will have to parse the output)whoami
does not exist (by default)who am I
prints owner of current terminal (ignores EUID)$USER
variable is set correctly only after reading profile files (for example, /etc/profile
)You can check your all defined function by
$arr = get_defined_functions();
print_r($arr);
this will give you array of all functions in if your function exist in it you can use it like:
{{ user.myfunction({{parameter}}) }}
You wanted to change the layout at runtime on button click. But that is not possible and as it has been rightly stated above, you need to restart the activity. You will come across a similar problem when u plan on changing the theme based on user's selection but it will not reflect in runtime. You will have to restart the activity.
You can use a try/catch clause and check to see if it exist:
try
{
if (!Directory.Exists(path))
{
// Try to create the directory.
DirectoryInfo di = Directory.CreateDirectory(path);
}
}
catch (IOException ioex)
{
Console.WriteLine(ioex.Message);
}

<input type=radio name=rdbExampleInfo id=rdbExamples value="select 3">
<input type=radio name=rdbExampleInfo id=rdbExamples value="select 4">
etc then use just
$("#rdbExamples:checked").val()
Or
$('input[name="rdbExampleInfo"]:checked').val();
Just to update this thread, here is how to add a list (as a json array) into JSONObject. Plz substitute YourClass with your class name;
List<YourClass> list = new ArrayList<>();
JSONObject jsonObject = new JSONObject();
org.codehaus.jackson.map.ObjectMapper objectMapper = new
org.codehaus.jackson.map.ObjectMapper();
org.codehaus.jackson.JsonNode listNode = objectMapper.valueToTree(list);
org.json.JSONArray request = new org.json.JSONArray(listNode.toString());
jsonObject.put("list", request);
Instead of getting the frame from the document, try getting the frame from the window object.
in the above example change this:
if (typeof (document.all.resultFrame.Reset) == "function")
document.all.resultFrame.Reset();
else
alert("resultFrame.Reset NOT found");
to
if (typeof (window.frames[0].Reset) == "function")
window.frames[0].Reset();
else
alert("resultFrame.Reset NOT found");
the problem is that the scope of the javascript inside the iframe is not exposed through the DOM element for the iframe. only window objects contain the javascript scoping information for the frames.
Convert your date column to the correct format and compare:
SELECT * From my_table WHERE to_char(my_table.my_date_col,'MM/dd/yyyy') = '8/3/2010'
This part
to_char(my_table.my_date_col,'MM/dd/yyyy')
Will result in string '8/3/2010'
This function uses the current millisecond time to subtract the current week, and then subtracts one more week if the current date is on a monday (javascript counts from sunday).
function getMonday(fromDate) {
// length of one day i milliseconds
var dayLength = 24 * 60 * 60 * 1000;
// Get the current date (without time)
var currentDate = new Date(fromDate.getFullYear(), fromDate.getMonth(), fromDate.getDate());
// Get the current date's millisecond for this week
var currentWeekDayMillisecond = ((currentDate.getDay()) * dayLength);
// subtract the current date with the current date's millisecond for this week
var monday = new Date(currentDate.getTime() - currentWeekDayMillisecond + dayLength);
if (monday > currentDate) {
// It is sunday, so we need to go back further
monday = new Date(monday.getTime() - (dayLength * 7));
}
return monday;
}
I have tested it when week spans over from one month to another (and also years), and it seems to work properly.
I don't have enough reputation points to comment but for those who are having problems with getting "unrecognized" when they try using Maciej Gurban's ResponsiveToolKit, I was also getting that error until I noticed that Maciej actually references the toolkit from the bottom of the page in his CodePen
I tried doing that and suddenly it worked ! So, use the ResponsiveToolkit but put your links in the bottom of the page:
I don't know why it makes a difference but it does.
Using findDOMNode is going to be deprecated eventually.

{
string[] parts = segment.Split('=');
if (parts.Length > 0)
{

string val = parts[1].Trim();
queryParameters.Add(key, val);

<option value="1">LONG OPTION</option>
<option value="2">short</option>
</select>
e.g.
style="width:200px"
In Windows, you should go: Start > Run > services.msc > Apache 2.4 > Properties > Start Mode > Automatic > Apply > Start > OK > [Same as MySQL]
Of course. if you are running on Tensorflow or CNTk backends, your code will run on your GPU devices defaultly.But if Theano backends, you can use following
Theano flags:
"THEANO_FLAGS=device=gpu,floatX=float32 python my_keras_script.py"
-- First Truncate temporary table SQL> TRUNCATE TABLE test_temp1; -- Then Drop temporary table SQL> DROP TABLE test_temp1;
java.util.regex.Pattern.matcher(CharSequence s) can use a StringBuilder as an argument so you can find and replace each occurence of your pattern using start() and end() without calling builder.toString()
I'm using latest TS and node (v2.6 and v8.9 respectively) and I can do:
let myMap = new Map<string, boolean>();
myMap.set("a", true);
for (let [k, v] of myMap) {
console.log(k + "=" + v);
}
What happens if the fragment that you want to remove is not on top of the stack?
Then you can use theses functions
This method holds instructions to paint this component. Actually, in Swing, you should change paintComponent() instead of paint(), as paint calls paintBorder(), paintComponent() and paintChildren(). You shouldn't call this method directly, you should call repaint() instead.
This method can't be overridden. It controls the update() -> paint() cycle. You should call this method to get a component to repaint itself. If you have done anything to change the look of the component, but not its size ( like changing color, animating, etc. ) then call this method.
You can try change your type connection to branch from ssh to https.
nano project_path/.git/config
[email protected]:username/repository.git
to https://[email protected]/username/repository_name.git
ctrl
+ o
After that you can try git pull
without publickey
use an enum type to indicate your ViewModel's State
public enum ViewModeType
{
Default,
Busy
//etc.
}
then in your ViewModels Base class use a property
public ViewModeType ViewMode
{
get { return this.viewMode; }
set
{
if (this.viewMode != value)
{
this.viewMode = value;
//You should notify property changed here
}
}
}
and in view trigger the ViewMode and if it is busy show busyindicator:
<Trigger Property="ViewMode" Value="Busy">
<!-- Show BusyIndicator -->
</Trigger>
start "systemLogCollector" /min cmd /k call systemLogCollector.bat
start "uiLogCollector" /min cmd /k call uiLogCollector.bat
start "appLogCollector" /min cmd /k call appLogCollector.bat
Here three batch files are run on separate command windows in a minimized state. If you don't want them minimized, then remove /min
. Also, if you don't need to control them later, then you can get rid of the titles. So, a bare-bone command will be- start cmd /k call systemLogCollector.bat
If you want to terminate them-
taskkill /FI "WindowTitle eq appLogCollector*" /T /F
taskkill /FI "WindowTitle eq uiLogCollector*" /T /F
taskkill /FI "WindowTitle eq systemLogCollector*" /T /F
A very good way of doing environment variables I have successfully used is below:
A. Have different config files:
dev.js // this has all environment variables for development only
The file contains:
module.exports = {
ENV: 'dev',
someEnvKey1 : 'some DEV Value1',
someEnvKey2 : 'some DEV Value2'
};
stage.js // this has all environment variables for development only
..
qa.js // this has all environment variables for qa testing only
The file contains:
module.exports = {
ENV: 'dev',
someEnvKey1 : 'some QA Value1',
someEnvKey2 : 'some QA Value2'
};
NOTE: the values are changing with the environment, mostly, but keys remain same.
you can have more
z__prod.js // this has all environment variables for production/live only
NOTE: This file is never bundled for deployment
Put all these config files in /config/ folder
<projectRoot>/config/dev.js
<projectRoot>/config/qa.js
<projectRoot>/config/z__prod.js
<projectRoot>/setenv.js
<projectRoot>/setenv.bat
<projectRoot>/setenv.sh
NOTE: The name of prod is different than others, as it would not be used by all.
B. Set the OS/ Lambda/ AzureFunction/ GoogleCloudFunction environment variables from config file
Now ideally, these config variables in file, should go as OS environment variables (or, LAMBDA function variables, or, Azure function variables, Google Cloud Functions, etc.)
so, we write automation in Windows OS (or other)
Assume we write 'setenv' bat file, which takes one argument that is environment that we want to set
Now run "setenv dev"
a) This takes the input from the passed argument variable ('dev' for now)
b) read the corresponding file ('config\dev.js')
c) sets the environment variables in Windows OS (or other)
For example,
The setenv.bat contents might be:
node setenv.js
The setenv.js contents might be:
// import "process.env.ENV".js file (dev.js example)
// loop the imported file contents
// set the environment variables in Windows OS (or, Lambda, etc.)
That's all, your environment is ready for use.
When you do 'setenv qa', all qa environment variables will be ready for use from qa.js, and ready for use by same program (which always asks for process.env.someEnvKey1, but the value it gets is qa one).
Hope that helps.
Not very "elegant" and kinda a waste, but if you really care what the code looks like you could make your own fancy flag and then do a str_replace.
Example:<br />
$myoutput = "After this sentence there is a line break.<b>.|..</b> Here is a new line.";<br />
$myoutput = str_replace(".|..","<br />",$myoutput);<br />
or
how about:<br />
$myoutput = "After this sentence there is a line break.<b>E(*)3</b> Here is a new line.";<br />
$myoutput = str_replace("E(*)3","<br />",$myoutput);<br />
I call the first method "middle finger style" and the second "goatse style".
In my case no shell was supported in container except sh
. So, this worked like a charm
docker exec -it <container-name> sh
So I haven't been able to get the Mesh Colliders to work. I created a composite collider using simple box colliders and it worked exactly as expected.
Other tests with simple Mesh Colliders have come out the same.
It looks like the best answer is to build a composite collider out of simple box/sphere colliders.
For my specific case I wrote a Wizard that creates a Pipe shaped compound collider.
@script AddComponentMenu("Colliders/Pipe Collider");
class WizardCreatePipeCollider extends ScriptableWizard
{
public var outterRadius : float = 200;
public var innerRadius : float = 190;
public var sections : int = 12;
public var height : float = 20;
@MenuItem("GameObject/Colliders/Create Pipe Collider")
static function CreateWizard()
{
ScriptableWizard.DisplayWizard.<WizardCreatePipeCollider>("Create Pipe Collider");
}
public function OnWizardUpdate() {
helpString = "Creates a Pipe Collider";
}
public function OnWizardCreate() {
var theta : float = 360f / sections;
var width : float = outterRadius - innerRadius;
var sectionLength : float = 2 * outterRadius * Mathf.Sin((theta / 2) * Mathf.Deg2Rad);
var container : GameObject = new GameObject("Pipe Collider");
var section : GameObject;
var sectionCollider : GameObject;
var boxCollider : BoxCollider;
for(var i = 0; i < sections; i++)
{
section = new GameObject("Section " + (i + 1));
sectionCollider = new GameObject("SectionCollider " + (i + 1));
section.transform.parent = container.transform;
sectionCollider.transform.parent = section.transform;
section.transform.localPosition = Vector3.zero;
section.transform.localRotation.eulerAngles.y = i * theta;
boxCollider = sectionCollider.AddComponent.<BoxCollider>();
boxCollider.center = Vector3.zero;
boxCollider.size = new Vector3(width, height, sectionLength);
sectionCollider.transform.localPosition = new Vector3(innerRadius + (width / 2), 0, 0);
}
}
}
I usually use svn through a gui, either my IDE or a client. Because of that, I can never remember the codes when I do have to resort to the command line.
I find this cheat sheet a great help: Subversion Cheat Sheet
A QueryString is, by definition, in the URL. You can access the URL of the request using req.URL
(doc). The URL object has a Query()
method (doc) that returns a Values
type, which is simply a map[string][]string
of the QueryString parameters.
If what you're looking for is the POST data as submitted by an HTML form, then this is (usually) a key-value pair in the request body. You're correct in your answer that you can call ParseForm()
and then use req.Form
field to get the map of key-value pairs, but you can also call FormValue(key)
to get the value of a specific key. This calls ParseForm()
if required, and gets values regardless of how they were sent (i.e. in query string or in the request body).
If copy assignment operator of foo and bar is cheap (eg. int, char, pointer etc), you can do the following:
foo f; bar b;
BOOST_FOREACH(boost::tie(f,b),testing)
{
cout << "Foo is " << f << " Bar is " << b;
}
An array list is essentially an array with methods to add items etc. (and you should use a generic list instead). It is a collection of items which can be accessed through an indexer (for example [0]). It implies a progression from one item to the next.
A linked list specifies a progression from one item to the next (Item a -> item b). You can get the same effect with an array list, but a linked list absolutely says what item is supposed to follow the previous one.
Try this one -
"SELECT
ID, Salt, password, BannedEndDate
, (
SELECT COUNT(1)
FROM dbo.LoginFails l
WHERE l.UserName = u.UserName
AND IP = '" + Request.ServerVariables["REMOTE_ADDR"] + "'
) AS cnt
FROM dbo.Users u
WHERE u.UserName = '" + LoginModel.Username + "'"
I'm using a workaround by returning a function with an object of my global variables:
function globalVariables(){
var variables = {
sheetName: 'Sheet1',
variable1: 1,
variable2: 2
};
return variables;
}
function functionThatUsesVariable (){
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(globalVariables().sheetName);
}
In such cases, you can convert the values of enum to a List and stream through it. Something like below examples. I would recommend using filter().
Using ForEach:
List<Category> category = Arrays.asList(Category.values());
category.stream().forEach(eachCategory -> {
if(eachCategory.toString().equals("3")){
String name = eachCategory.name();
}
});
Or, using Filter:
When you want to find with code:
List<Category> categoryList = Arrays.asList(Category.values());
Category category = categoryList.stream().filter(eachCategory -> eachCategory.toString().equals("3")).findAny().orElse(null);
System.out.println(category.toString() + " " + category.name());
When you want to find with name:
List<Category> categoryList = Arrays.asList(Category.values());
Category category = categoryList.stream().filter(eachCategory -> eachCategory.name().equals("Apple")).findAny().orElse(null);
System.out.println(category.toString() + " " + category.name());
Hope it helps! I know this is a very old post, but someone can get help.
You can create a macro for Ctrl +Shift + S (for example) that do all this things:
Edit > Macros > Start Macro Recording (the recording will start). Click where you need.
For example:
Code > Reformat Code
Code > Auto-Indent Lines
Code > Optimize Imports
Code > Rearrange Code
File > Save All
... (all that you want)
Then, click on red button in bottom-right of the IDE to stop the Macro recording.
Set a macro name.
Go to File > Settings > Macros > YOUR MACRO NAME.
Right Click > Add Keyboard Shortcut, and type Ctrl + Shift + S.
Clicking Properties, going to the Service tab and setting Start Mode to Automatic fixed the problem for me. Now the Start item in the context menu is active again.
Add to your .gitconfig
under [alias]
:
aliases = !git config --list | grep ^alias\\. | cut -c 7- | grep -Ei --color \"$1\" "#"
Then you can do
git aliases
- show ALL aliasesgit aliases commit
- only aliases containing "commit"Simply write one line in the constructor:
setResizable(false);
This will make it impossible to resize the frame.
The problem here is that the rendering of a RadioButtonList wraps the individual radio buttons (ListItems) in span tags and even when you assign a client-side event handler to the list item directly using Attributes it assigns the event to the span. Assigning the event to the RadioButtonList assigns it to the table it renders in.
The trick here is to add the ListItems on the aspx page and not from the code behind. You can then assign the JavaScript function to the onClick property. This blog post; attaching client-side event handler to radio button list by Juri Strumpflohner explains it all.
This only works if you know the ListItems in advance and does not help where the items in the RadioButtonList need to be dynamically added using the code behind.
I use the following method to calculate the desired image size:
using System.Drawing;
public static Size ResizeKeepAspect(this Size src, int maxWidth, int maxHeight, bool enlarge = false)
{
maxWidth = enlarge ? maxWidth : Math.Min(maxWidth, src.Width);
maxHeight = enlarge ? maxHeight : Math.Min(maxHeight, src.Height);
decimal rnd = Math.Min(maxWidth / (decimal)src.Width, maxHeight / (decimal)src.Height);
return new Size((int)Math.Round(src.Width * rnd), (int)Math.Round(src.Height * rnd));
}
This puts the problem of aspect ratio and dimensions in a separate method.
You can also try this:
ini_set("max_execution_time", "-1");
ini_set("memory_limit", "-1");
ignore_user_abort(true);
set_time_limit(0);
I don't know if my solution is best practice, but I achieved loading a bitmap with my desired scaling by using the inDensity
and inTargetDensity
options. inDensity
is 0
initially when not loading a drawable resource, so this approach is for loading non resource images.
The variables imageUri
, maxImageSideLength
and context
are parameters of my method. I posted only the method implementation without the wrapping AsyncTask for clarity.
ContentResolver resolver = context.getContentResolver();
InputStream is;
try {
is = resolver.openInputStream(imageUri);
} catch (FileNotFoundException e) {
Log.e(TAG, "Image not found.", e);
return null;
}
Options opts = new Options();
opts.inJustDecodeBounds = true;
BitmapFactory.decodeStream(is, null, opts);
// scale the image
float maxSideLength = maxImageSideLength;
float scaleFactor = Math.min(maxSideLength / opts.outWidth, maxSideLength / opts.outHeight);
// do not upscale!
if (scaleFactor < 1) {
opts.inDensity = 10000;
opts.inTargetDensity = (int) ((float) opts.inDensity * scaleFactor);
}
opts.inJustDecodeBounds = false;
try {
is.close();
} catch (IOException e) {
// ignore
}
try {
is = resolver.openInputStream(imageUri);
} catch (FileNotFoundException e) {
Log.e(TAG, "Image not found.", e);
return null;
}
Bitmap bitmap = BitmapFactory.decodeStream(is, null, opts);
try {
is.close();
} catch (IOException e) {
// ignore
}
return bitmap;
You could use :before
and content:
bearing in mind that this is not supported in IE 7 or below. If you're OK with that then this is your best solution. See the Can I Use or QuirksMode CSS compatibility tables for full details.
A slightly nastier solution that should work in older browsers is to use an image for the bullet point and just make the image look like a dash. See the W3C list-style-image
page for examples.
If you have source as a string like "abcd"
and want to produce a list like this:
{ "a.a" },
{ "b.b" },
{ "c.c" },
{ "d.d" }
then call:
List<string> list = source.Select(c => String.Concat(c, ".", c)).ToList();
I looked all over for an easy solution and found this code that worked for me. The right
div is a third column which I left in for readability sake.
Here is the HTML:
<div class="container">
<div class="row">
<div class="left">
<p>PHONE & FAX:</p>
</div>
<div class="middle">
<p>+43 99 554 28 53</p>
</div>
<div class="right"> </div>
</div>
<div class="row">
<div class="left">
<p>Cellphone Gert:</p>
</div>
<div class="middle">
<p>+43 99 302 52 32</p>
</div>
<div class="right"> </div>
</div>
<div class="row">
<div class="left">
<p>Cellphone Petra:</p>
</div>
<div class="middle">
<p>+43 99 739 38 84</p>
</div>
<div class="right"> </div>
</div>
</div>
And the CSS:
.container {
display: table;
}
.row {
display: table-row;
}
.left, .right, .middle {
display: table-cell;
padding-right: 25px;
}
.left p, .right p, .middle p {
margin: 1px 1px;
}
Here's the jQuery one-liner:
$('<a>').attr('href', url).prop('hostname');
I wanted the changes in Git to be shown as moves/renames instead of delete & adds. So I did a combo of the above and this post.
mkdir subdirectory
git mv -k ./* ./subdirectory
# check to make sure everything moved (see below)
git commit
And adjust the paths of the projects and of the assemblies from the nuget Pkg's in the sln file via a text editor.
This is a way I did it pretty simply:
YourWindow.xaml.cs
//In your constructor
public YourWindow()
{
InitializeComponent();
DataContext = new YourWindowViewModel(this);
}
YourWindowViewModel.cs
private YourWindow window;//so we can kill the window
//In your constructor
public YourWindowViewModel(YourWindow window)
{
this.window = window;
}
//to close the window
public void CloseWindow()
{
window.Close();
}
I don't see anything wrong with the answer you chose, I just thought this might be a more simple way to do it!
I would suggest chop
. I think it has been mentioned in one of the comments but without links or explanations so here's why I think it's better:
It simply removes the last character from a string and you don't have to specify any values for that to happen.
If you need to remove more than one character then chomp
is your best bet. This is what the ruby docs have to say about chop
:
Returns a new String with the last character removed. If the string ends with \r\n, both characters are removed. Applying chop to an empty string returns an empty string. String#chomp is often a safer alternative, as it leaves the string unchanged if it doesn’t end in a record separator.
Although this is used mostly to remove separators such as \r\n
I've used it to remove the last character from a simple string, for example the s
to make the word singular.
std::string str;
char* const s = "test";
str.assign(s);
string& assign (const char* s); => signature FYR
Reference/s here.
You can't do what you're asking natively with an array, but javascript objects are hashes, so you can say...
var hash = {};
hash['k1'] = 'abc';
...
Then you can retrieve using bracket or dot notation:
alert(hash['k1']); // alerts 'abc'
alert(hash.k1); // also alerts 'abc'
For arrays, check the underscore.js library in general and the detect method in particular. Using detect you could do something like...
_.detect(arr, function(x) { return x.name == 'k1' });
Or more generally
MyCollection = function() {
this.arr = [];
}
MyCollection.prototype.getByName = function(name) {
return _.detect(this.arr, function(x) { return x.name == name });
}
MyCollection.prototype.push = function(item) {
this.arr.push(item);
}
etc...
AllDogs.First(d => d.Id == "2").Name = "some value";
However, a safer version of that might be this:
var dog = AllDogs.FirstOrDefault(d => d.Id == "2");
if (dog != null) { dog.Name = "some value"; }
I was coding in the dark (a challenge) and couldn't lookup or test my code.
I forgot what round up was called (Math.celi) So I wanted to be extra sure i got it right and came up with this code.
var elm = document.createElement('input')_x000D_
elm.type = 'week'_x000D_
elm.valueAsDate = new Date()_x000D_
var week = elm.value.split('W').pop()_x000D_
_x000D_
console.log(week)
_x000D_
But still i recommend any other solution that isn't required by the DOM.
Try this.
objectMapper.enable(SerializationConfig.Feature.INDENT_OUTPUT);
To directly answer this question's original title "How to delete rows from a pandas DataFrame based on a conditional expression" (which I understand is not necessarily the OP's problem but could help other users coming across this question) one way to do this is to use the drop method:
df = df.drop(some labels)
df = df.drop(df[<some boolean condition>].index)
Example
To remove all rows where column 'score' is < 50:
df = df.drop(df[df.score < 50].index)
In place version (as pointed out in comments)
df.drop(df[df.score < 50].index, inplace=True)
Multiple conditions
(see Boolean Indexing)
The operators are:
|
foror
,&
forand
, and~
fornot
. These must be grouped by using parentheses.
To remove all rows where column 'score' is < 50 and > 20
df = df.drop(df[(df.score < 50) & (df.score > 20)].index)
Create a class TestUserDetailsImpl
on your test package:
@Service
@Primary
@Profile("test")
public class TestUserDetailsImpl implements UserDetailsService {
public static final String API_USER = "[email protected]";
private User getAdminUser() {
User user = new User();
user.setUsername(API_USER);
SimpleGrantedAuthority role = new SimpleGrantedAuthority("ROLE_API_USER");
user.setAuthorities(Collections.singletonList(role));
return user;
}
@Override
public UserDetails loadUserByUsername(String username)
throws UsernameNotFoundException {
if (Objects.equals(username, ADMIN_USERNAME))
return getAdminUser();
throw new UsernameNotFoundException(username);
}
}
Rest endpoint:
@GetMapping("/invoice")
@Secured("ROLE_API_USER")
public Page<InvoiceDTO> getInvoices(){
...
}
Test endpoint:
@Test
@WithUserDetails("[email protected]")
public void testApi() throws Exception {
...
}
My first thought is you could use git rev-list HEAD
, which lists all the revs in reverse chronological order, in combination with git tag --contains
. When you find a ref where git tag --contains
produces a nonempty list, you have found the most recent tag(s).
Who ever also stumbles over this post.
I belive is the correct way:
<div *ngFor="let appointment of (_nextFourAppointments | async).availabilities;">
<div>{{ appointment }}</div>
</div>
This works too:
System.DateTime dTime = DateTime.Now();
// tSpan is 0 days, 1 hours, 30 minutes and 0 second.
System.TimeSpan tSpan = new System.TimeSpan(0, 1, 3, 0);
System.DateTime result = dTime + tSpan;
To subtract a year:
DateTime DateEnd = DateTime.Now;
DateTime DateStart = DateEnd - new TimeSpan(365, 0, 0, 0);
It doesn't even show the "Hello World" in the preview when i started my first project,only displays 'Rendering problem' and 'Failed to instantiates one or more class'.This helps me out, try this.....
in the left side menu, GoTo
base-> res-> values-> styles.xml
then write "Base." in the line <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
just before the Theme.AppCompat i.e <style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
Consider a similar situation in conversation. Imagine your friend says to you, "Bob is coming over for dinner," and you have no idea who Bob is. You're going to be confused, right? Your friend should have said, "I have a work colleague called Bob. Bob is coming over for dinner." Now Bob has been declared and you know who your friend is talking about.
The compiler emits an 'undeclared identifier' error when you have attempted to use some identifier (what would be the name of a function, variable, class, etc.) and the compiler has not seen a declaration for it. That is, the compiler has no idea what you are referring to because it hasn't seen it before.
If you get such an error in C or C++, it means that you haven't told the compiler about the thing you are trying to use. Declarations are often found in header files, so it likely means that you haven't included the appropriate header. Of course, it may be that you just haven't remembered to declare the entity at all.
Some compilers give more specific errors depending on the context. For example, attempting to compile X x;
where the type X
has not been declared with clang will tell you "unknown type name X
". This is much more useful because you know it's trying to interpret X
as a type. However, if you have int x = y;
, where y
is not yet declared, it will tell you "use of undeclared identifier y
" because there is some ambiguity about what exactly y
might represent.
I had a similar problem and found that if you remove the size definition, it works for some reason.
Remove:
<size
android:width="60dp"
android:height="40dp" />
from the shape.
Let me know if this works!
There's a great piece of code related to the resizing of images + several other operations. I came around this one when trying to figure ou how to resize images... http://vocaro.com/trevor/blog/2009/10/12/resize-a-uiimage-the-right-way/
yum update
helped me out. After I had

The following statement is not entirely accurate:
"So if you are calling other functionality, including static classes, from your page, you should be fine"
I am calling a static method that references the session through HttpContext.Current.Session and it is null. However, I am calling the method via a webservice method through ajax using jQuery.
As I found out here you can fix the problem with a simple attribute on the method, or use the web service session object:
There’s a trick though, in order to access the session state within a web method, you must enable the session state management like so:
[WebMethod(EnableSession = true)]
By specifying the EnableSession value, you will now have a managed session to play with. If you don’t specify this value, you will get a null Session object, and more than likely run into null reference exceptions whilst trying to access the session object.
Thanks to Matthew Cosier for the solution.
Just thought I'd add my two cents.

Use svn cat
or svn export
.
For that, you don't need to fetch the working directory, but you will not be able to commit any changes you make. If you need to make changes and commit them, you need a working directory, but you don't have to fetch it completely. Checkout the revision where the directory was still/almost empty, and then use 'svn cat' to extract the file from HEAD.
One might consider adding this line to ~/.bash_profile
(or similar) in order to can quickly get the current UTC both as current time and as seconds since the epoch.
alias utc='date -u && date -u +%s'
you can do it as follow:
$("#addButton").click(function () {
if(counter>10){
alert("Only 10 textboxes allow");
return false;
}
var newTextBoxDiv = $(document.createElement('div'))
.attr("id", 'TextBoxDiv' + counter);
newTextBoxDiv.after().html('<label>Textbox #'+ counter + ' : </label>' +
'<input type="text" name="textbox' + counter +
'" id="textbox' + counter + '" value="" >');
newTextBoxDiv.appendTo("#TextBoxesGroup");
counter++;
});
$("#removeButton").click(function () {
if(counter==1){
alert("No more textbox to remove");
return false;
}
counter--;
$("#TextBoxDiv" + counter).remove();
});

Express 3.x no longer support partial. According to the post ejs 'partial is not defined', you can use "include" keyword in EJS to replace the removed partial functionality.
For the asynchronous dispatch case you describe above, you shouldn't need to check if you're on the main thread. As Bavarious indicates, this will simply be queued up to be run on the main thread.
However, if you attempt to do the above using a dispatch_sync()
and your callback is on the main thread, your application will deadlock at that point. I describe this in my answer here, because this behavior surprised me when moving some code from -performSelectorOnMainThread:
. As I mention there, I created a helper function:
void runOnMainQueueWithoutDeadlocking(void (^block)(void))
{
if ([NSThread isMainThread])
{
block();
}
else
{
dispatch_sync(dispatch_get_main_queue(), block);
}
}
which will run a block synchronously on the main thread if the method you're in isn't currently on the main thread, and just executes the block inline if it is. You can employ syntax like the following to use this:
runOnMainQueueWithoutDeadlocking(^{
//Do stuff
});

You can solve this problem by following two ways:
A) Start your WAMP befor you login to skype. So that WAMP will take over the the port and there will be no conflict with the port number. And you are able to use Skype as well as WAMP.
But this is not the permanent solution for your problem. Whenever you want to start WAMP you need to signout Skype first and than only you are able to start WAMP. Which is really i don’t like.
B) Second option is to change the port of Skype itself, so that it will not conflict with WAMP. Following screen/steps will help you to solve this problem:
1) SignIn to Skype.
2) Got to the Tools -> options
3) Select the “Advanced” -> Connection
4) Unchecked “Use port 80 and 443 as alternatives for incoming connections” checkbox and click save.
5) Now Signout and SignIn again to skype. (this change will take affect only you relogin to skype)
Now every time you start WAMP will not conflict with skype.
Take a look at PyCrypto. It supports Python 3.2 and does exactly what you want.
From their pip website:
>>> from Crypto.Cipher import AES
>>> obj = AES.new('This is a key123', AES.MODE_CFB, 'This is an IV456')
>>> message = "The answer is no"
>>> ciphertext = obj.encrypt(message)
>>> ciphertext
'\xd6\x83\x8dd!VT\x92\xaa`A\x05\xe0\x9b\x8b\xf1'
>>> obj2 = AES.new('This is a key123', AES.MODE_CFB, 'This is an IV456')
>>> obj2.decrypt(ciphertext)
'The answer is no'
If you want to encrypt a message of an arbitrary size use AES.MODE_CFB
instead of AES.MODE_CBC
.
As of Android 3.0 (API Level 11) Android has a more recent and improved JSON Parser.
http://developer.android.com/reference/android/util/JsonReader.html
Reads a JSON (RFC 4627) encoded value as a stream of tokens. This stream includes both literal values (strings, numbers, booleans, and nulls) as well as the begin and end delimiters of objects and arrays. The tokens are traversed in depth-first order, the same order that they appear in the JSON document. Within JSON objects, name/value pairs are represented by a single token.
One more solution when you want to use data from any sell ( in the key C3
)
=SUMIF(Sheet6!M:M;CONCATENATE("<";TEXT(C3;"dd.mm.yyyy"));Sheet6!L:L)
Use 'Smalldatetime' data type
select convert(smalldatetime, getdate())
will fetch

Rank(), Dense_rank(), row_number()
These all are window functions that means they act as window over some ordered input set at first. These windows have different functionality attached to it based on the requirement. Heres the above 3 :
row_number()
Starting by row_number()
as this forms the basis of these related window functions. row_number()
as the name suggests gives a unique number to the set of rows over which its been applied. Similar to giving a serial number to each row.
Rank()
A subversion of row_number()
can be said as rank()
. Rank() is used to give same serial number to those ordered set rows which are duplicates but it still keeps the count mantained as similar to a row_number()
for all those after duplicates rank() meaning as from below eg. For data 2 row_number() =rank() meaning both just differs in the form of duplicates.
Data row_number() rank() dense_rank()
1 1 1 1
1 2 1 1
1 3 1 1
2 4 4 2
Finally,
Dense_rank() is an extended version of rank() as the name suggests its dense because as you can see from the above example rank() = dense_rank() for all data 1 but just that for data 2 it differs in the form that it mantains the order of rank() from previous rank() not the actual data
I was getting this error and switched the queries to async (await (...).ToListAsync()). All good now.
It seems like you can also use the patch command. Put the diff in the root of the repository and run patch
from the command line.
patch -i yourcoworkers.diff
or
patch -p0 -i yourcoworkers.diff
You may need to remove the leading folder structure if they created the diff without using --no-prefix
.
If so, then you can remove the parts of the folder that don't apply using:
patch -p1 -i yourcoworkers.diff
The -p(n) signifies how many parts of the folder structure to remove.
More information on creating and applying patches here.
You can also use
git apply yourcoworkers.diff --stat
to see if the diff by default will apply any changes. It may say 0 files affected if the patch is not applied correctly (different folder structure).
This is probably what you're looking for:
select * from TABLE where COLUMN regexp '[^ -~]';
It should return all rows where COLUMN contains non-ASCII characters (or non-printable ASCII characters such as newline).
If you use NavigationController in Swift 2.x
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let targetViewController = storyboard.instantiateViewControllerWithIdentifier("targetViewControllerID") as? TargetViewController
self.navigationController?.pushViewController(targetViewController!, animated: true)
You can't update more that one table in a single statement, however the error message you get is because of the aliases, you could try this :
BEGIN TRANSACTION
update A
set A.ORG_NAME = @ORG_NAME
from table1 A inner join table2 B
on B.ORG_ID = A.ORG_ID
and A.ORG_ID = @ORG_ID
update B
set B.REF_NAME = @REF_NAME
from table2 B inner join table1 A
on B.ORG_ID = A.ORG_ID
and A.ORG_ID = @ORG_ID

I recently was wondering why my code doesn't work, then I realized, I need to setup the event handlers as soon as the document is loaded, otherwise when browser loads the code line by line, it loads the JavaScript, but it does not yet have the element to assign the event handler to it. with your example, it should be like this:
$(document).ready(function(){
$("#kat").change(function(){
alert("Hello");
});
});
On CENTOS 6 /etc/my.cnf , under [mysqld] section the correct syntax is:
[mysqld]
# added to avoid err "Got a packet bigger than 'max_allowed_packet' bytes"
#
net_buffer_length=1000000
max_allowed_packet=1000000000
#
This is not possible with the magic find methods. Try using the query builder:
$result = $em->getRepository("Orders")->createQueryBuilder('o')
->where('o.OrderEmail = :email')
->andWhere('o.Product LIKE :product')
->setParameter('email', '[email protected]')
->setParameter('product', 'My Products%')
->getQuery()
->getResult();
Just generalising the query if you want to work with any given date instead of current date:
SELECT Table.date
FROM Table
WHERE Table.date > '2020-01-01'::date - interval '10 day'
You mention that there are date duplicates, but it appears they're quite unique down to the precision of seconds.
Can you clarify what precision of date you start considering dates duplicate - day, hour, minute?
In any case, you'll probably want to floor your datetime field. You didn't indicate which field is preferred when removing duplicates, so this query will prefer the last name in alphabetical order.
SELECT MAX(owner_name),
--floored to the second
dateadd(second,datediff(second,'2000-01-01',start_date),'2000-01-01') AS StartDate
From MyTable
GROUP BY dateadd(second,datediff(second,'2000-01-01',start_date),'2000-01-01')
If you have a UITabController with Screens with Embeded Navigation Controllers, you have to set the UITabController Presentation to FullScreen as shown in pic below
The Java Language Specification, section 15.10, states:
An array creation expression creates an object that is a new array whose elements are of the type specified by the PrimitiveType or ClassOrInterfaceType. It is a compile-time error if the ClassOrInterfaceType does not denote a reifiable type (§4.7).
and
The rules above imply that the element type in an array creation expression cannot be a parameterized type, other than an unbounded wildcard.
The closest you can do is use an unchecked cast, either from the raw type, as you have done, or from an unbounded wildcard:
HashMap<String, String>[] responseArray = (Map<String, String>[]) new HashMap<?,?>[games.size()];
Your version is clearly better :-)
If you set the server output in ON mode before the entire code, it works, otherwise put_line() will not work. Try it!
The code is,
set serveroutput on;
CREATE OR REPLACE PROCEDURE PROC1(invoicenr IN NUMBER, amnt OUT NUMBER)
AS BEGIN
SELECT AMOUNT INTO amnt FROM INVOICE WHERE INVOICE_NR = invoicenr;
END;
And then call the function as it is:
DECLARE
amount NUMBER;
BEGIN
PROC1(1000001, amount);
dbms_output.put_line(amount);
END;
For the line
line.split()
What are you splitting on? Looks like a CSV, so try
line.split(',')
Example:
"one,two,three".split() # returns one element ["one,two,three"]
"one,two,three".split(',') # returns three elements ["one", "two", "three"]
As @TigerhawkT3 mentions, it would be better to use the CSV module. Incredibly quick and easy method available here.
In Postgres 9.4 or later, this is simplest and fastest:
SELECT c.*
FROM comments c
JOIN unnest('{1,3,2,4}'::int[]) WITH ORDINALITY t(id, ord) USING (id)
ORDER BY t.ord;
WITH ORDINALITY
was introduced with in Postgres 9.4.
No need for a subquery, we can use the set-returning function like a table directly. (A.k.a. "table-function".)
A string literal to hand in the array instead of an ARRAY constructor may be easier to implement with some clients.
For convenience (optionally), copy the column name we are joining to (id
in the example), so we can join with a short USING
clause to only get a single instance of the join column in the result.
Detailed explanation:
Another intuitive solution could be:
class Post
{
public $title;
public $date;
}
$posts = array();
$posts[0] = new Post();
$posts[0]->title = 'post sample 1';
$posts[0]->date = '1/1/2021';
$posts[1] = new Post();
$posts[1]->title = 'post sample 2';
$posts[1]->date = '2/2/2021';
foreach ($posts as $post) {
echo 'Post Title:' . $post->title . ' Post Date:' . $post->date . "\n";
}
You can try using:
select trunc(sysdate - to_date('2009-10-01', 'yyyy-mm-dd')) as days from dual
use this package react-native-keyboard-aware-scroll-view
use that component as your root component
since this package react-native-keyboard-aware-scroll-view
also have an scrollView you need to add this to it:
<KeyboardAwareScrollView keyboardShouldPersistTaps="handled">
<ScrollView keyboardShouldPersistTaps="handled"></ScrollView>
</KeyboardAwareScrollView>
1) What is Express.js?
Express.js is a Node.js framework. It's the most popular framework as of now (the most starred on NPM).
.
It's built around configuration and granular simplicity of Connect middleware. Some people compare Express.js to Ruby Sinatra vs. the bulky and opinionated Ruby on Rails.
2) What is the purpose of it with Node.js?
That you don't have to repeat same code over and over again. Node.js is a low-level I/O mechanism which has an HTTP module. If you just use an HTTP module, a lot of work like parsing the payload, cookies, storing sessions (in memory or in Redis), selecting the right route pattern based on regular expressions will have to be re-implemented. With Express.js, it is just there for you to use.
3) Why do we actually need Express.js? How it is useful for us to use with Node.js?
The first answer should answer your question. If no, then try to write a small REST API server in plain Node.js (that is, using only core modules) and then in Express.js. The latter will take you 5-10x less time and lines of code.
What is Redis? Does it come with Express.js?
Redis is a fast persistent key-value storage. You can optionally use it for storing sessions with Express.js, but you don't need to. By default, Express.js has memory storage for sessions. Redis also can be use for queueing jobs, for example, email jobs.
Check out my tutorial on REST API server with Express.js.
MVC but not by itself
Express.js is not an model-view-controller framework by itself. You need to bring your own object-relational mapping libraries such as Mongoose for MongoDB, Sequelize (http://sequelizejs.com) for SQL databases, Waterline (https://github.com/balderdashy/waterline) for many databases into the stack.
Alternatives
Other Node.js frameworks to consider (https://www.quora.com/Node-js/Which-Node-js-framework-is-best-for-building-a-RESTful-API):
UPDATE: I put together this resource that aid people in choosing Node.js frameworks: http://nodeframework.com
UPDATE2: We added some GitHub stats to nodeframework.com so now you can compare the level of social proof (GitHub stars) for 30+ frameworks on one page.
Full-stack:
Just REST API:
Ruby on Rails like:
Sinatra like:

Static site generators:
Bitmap bbicon;
bbicon=BitmapFactory.decodeResource(getResources(),R.drawable.bannerd10);
//ByteArrayOutputStream baosicon = new ByteArrayOutputStream();
//bbicon.compress(Bitmap.CompressFormat.PNG,0, baosicon);
//bicon=baosicon.toByteArray();
String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
OutputStream outStream = null;
File file = new File(extStorageDirectory, "er.PNG");
try {
outStream = new FileOutputStream(file);
bbicon.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();

If you are using pyenv, it is possible to delete your virtual environment:
$ pyenv virtualenv-delete <name>
How about this: It is Somewhat Efficient & Somewhat Simple. Only need to join '2' parts of url path:
def UrlJoin(a , b):
a, b = a.strip(), b.strip()
a = a if a.endswith('/') else a + '/'
b = b if not b.startswith('/') else b[1:]
return a + b
OR: More Conventional, but Not as efficient if joining only 2 url parts of a path.
def UrlJoin(*parts):
return '/'.join([p.strip().strip('/') for p in parts])
Test Cases:
>>> UrlJoin('https://example.com/', '/TestURL_1')
'https://example.com/TestURL_1'
>>> UrlJoin('https://example.com', 'TestURL_2')
'https://example.com/TestURL_2'
Note: I may be splitting hairs here, but it is at least good practice and potentially more readable.
class someclass:
x=1
y=2
z=3
def __init__(self):
self.current_idx = 0
self.items = ["x","y","z"]
def next(self):
if self.current_idx < len(self.items):
self.current_idx += 1
k = self.items[self.current_idx-1]
return (k,getattr(self,k))
else:
raise StopIteration
def __iter__(self):
return self
then just call it as an iterable
s=someclass()
for k,v in s:
print k,"=",v
Both C++ and C# are missing easy ways to create a new type which is semantically identical to an exisiting type. I find such 'typedefs' totally essential for type-safe programming and its a real shame c# doesn't have them built-in. The difference between void f(string connectionID, string username)
to void f(ConID connectionID, UserName username)
is obvious ...
(You can achieve something similar in C++ with boost in BOOST_STRONG_TYPEDEF)
It may be tempting to use inheritance but that has some major limitations:
The only way to achieve a similar thing in C# is by composing our type in a new class:
Class SomeType {
public void Method() { .. }
}
sealed Class SomeTypeTypeDef {
public SomeTypeTypeDef(SomeType composed) { this.Composed = composed; }
private SomeType Composed { get; }
public override string ToString() => Composed.ToString();
public override int GetHashCode() => HashCode.Combine(Composed);
public override bool Equals(object obj) => obj is TDerived o && Composed.Equals(o.Composed);
public bool Equals(SomeTypeTypeDefo) => object.Equals(this, o);
// proxy the methods we want
public void Method() => Composed.Method();
}
While this will work it is very verbose for just a typedef. In addition we have a problem with serializing (ie to Json) as we want to serialize the class through its Composed property.
Below is a helper class that uses the "Curiously Recurring Template Pattern" to make this much simpler:
namespace Typedef {
[JsonConverter(typeof(JsonCompositionConverter))]
public abstract class Composer<TDerived, T> : IEquatable<TDerived> where TDerived : Composer<TDerived, T> {
protected Composer(T composed) { this.Composed = composed; }
protected Composer(TDerived d) { this.Composed = d.Composed; }
protected T Composed { get; }
public override string ToString() => Composed.ToString();
public override int GetHashCode() => HashCode.Combine(Composed);
public override bool Equals(object obj) => obj is Composer<TDerived, T> o && Composed.Equals(o.Composed);
public bool Equals(TDerived o) => object.Equals(this, o);
}
class JsonCompositionConverter : JsonConverter {
static FieldInfo GetCompositorField(Type t) {
var fields = t.BaseType.GetFields(BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.FlattenHierarchy);
if (fields.Length!=1) throw new JsonSerializationException();
return fields[0];
}
public override bool CanConvert(Type t) {
var fields = t.GetFields(BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.FlattenHierarchy);
return fields.Length == 1;
}
// assumes Compositor<T> has either a constructor accepting T or an empty constructor
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer) {
while (reader.TokenType == JsonToken.Comment && reader.Read()) { };
if (reader.TokenType == JsonToken.Null) return null;
var compositorField = GetCompositorField(objectType);
var compositorType = compositorField.FieldType;
var compositorValue = serializer.Deserialize(reader, compositorType);
var ctorT = objectType.GetConstructor(new Type[] { compositorType });
if (!(ctorT is null)) return Activator.CreateInstance(objectType, compositorValue);
var ctorEmpty = objectType.GetConstructor(new Type[] { });
if (ctorEmpty is null) throw new JsonSerializationException();
var res = Activator.CreateInstance(objectType);
compositorField.SetValue(res, compositorValue);
return res;
}
public override void WriteJson(JsonWriter writer, object o, JsonSerializer serializer) {
var compositorField = GetCompositorField(o.GetType());
var value = compositorField.GetValue(o);
serializer.Serialize(writer, value);
}
}
}
With Composer the above class becomes simply:
sealed Class SomeTypeTypeDef : Composer<SomeTypeTypeDef, SomeType> {
public SomeTypeTypeDef(SomeType composed) : base(composed) {}
// proxy the methods we want
public void Method() => Composed.Method();
}
And in addition the SomeTypeTypeDef
will serialize to Json in the same way that SomeType
does.
Hope this helps !
Navigate to the "Get just the command line tools" section of the android downloads page, and download the tools for your system.
For Windows:
Extract the contents to C:\Android\android-sdk
Navigate to
C:\Android\android-sdk\tools\bin and open a command line window
(shift + right click)
Run the following to download the latest android package:
sdkmanager "platforms;android-25"
Update everything
sdkmanager --update
Other operation systems Do pretty much the same, but not using windows directories.
The sdkmanager page gives more info in to what commands to use to install your sdk.
Linux: First you can find PID of this command if you know the port :
netstat -tulpn
example:-
Local Address Foreign Address State PID/Program name
:::3000 :::* LISTEN 15986/node
You then take the kill process. run the following command:
kill -9 PID
Expample: -
kill -9 15986
if (e.attr("name") == "firstName" ) {
$("#firstName__validate").text($(error).text());
console.log($(error).html());
}
Try this get text of error object
I suggest you to have a look at the MySQL csv storage engine which essentially allows you to load any csv file (easily created from excel) into the database, once you have that, you can use any SQL command you want.
It's worth to have a look at it.
Personally I extract the POST array and then have if(!$login || !$password) then echo fill out the form :)
Well, I can think of a CSS hack that will resolve this issue.
You could add the following line in your CSS file:
* html .blog_list div.postbody img { width:75px; height: SpecifyHeightHere; }
The above code will only be seen by IE6. The aspect ratio won't be perfect, but you could make it look somewhat normal. If you really wanted to make it perfect, you would need to write some javascript that would read the original picture width, and set the ratio accordingly to specify a height.

You may try while loop as shown below;
def do1():
# Do something
def do2(x):
while x > 0:
do1()
x -= 1
do2(5)
Thus make call the do1 function 5 times.
The best way I've found to do it is run Reloader
It allows you to define configmaps or secrets to watch, when they get updated, a rolling update of your deployment is performed. Here's an example:
You have a deployment foo
and a ConfigMap called foo-configmap
. You want to roll the pods of the deployment every time the configmap is changed. You need to run Reloader with:
kubectl apply -f https://raw.githubusercontent.com/stakater/Reloader/master/deployments/kubernetes/reloader.yaml
Then specify this annotation in your deployment:
kind: Deployment
metadata:
annotations:
configmap.reloader.stakater.com/reload: "foo-configmap"
name: foo
...
How would I accomplish the nextsibling and is there an easier way of doing this?
You may use:
tr/td[@class='name']/following-sibling::td
but I'd rather use directly:
tr[td[@class='name'] ='Brand']/td[@class='desc']
This assumes that:
The context node, against which the XPath expression is evaluated is the parent of all tr
elements -- not shown in your question.
Each tr
element has only one td
with class
attribute valued 'name'
and only one td
with class
attribute valued 'desc'
.
Note that if you still want to exclude a set, including things like slashes and special characters you can do the following:
var outString = sourceString.replace(/[`~!@#$%^&*()_|+\-=?;:'",.<>\{\}\[\]\\\/]/gi, '');
take special note that in order to also include the "minus" character, you need to escape it with a backslash like the latter group. if you don't it will also select 0-9 which is probably undesired.
Just so others who have configured their apps like mine benefit from what I went through...
None of the above solutions worked for me because I have a ./config
directory just under my project base with 2 files:
application.properties
application-dev.properties
In application.properties
I have:
spring.profiles.active = dev # set my default profile to 'dev'
In application-dev.properties
I have:
server_host = localhost
server_port = 8080
This is so when I run my fat jar from the CLI the *.properties
files will be read from the ./config
dir and all is good.
Well, it turns out that these properties files completely override the webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT
setting in @SpringBootTest
in my Spock specs. No matter what I tried, even with webEnvironment
set to RANDOM_PORT
Spring would always startup the embedded Tomcat container on port 8080 (or whatever value I'd set in my ./config/*.properties
files).
The ONLY way I was able to overcome this was by adding an explicit properties = "server_port=0"
to the @SpringBootTest
annotation in my Spock integration specs:
@SpringBootTest (webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, properties = "server_port=0")
Then, and only then did Spring finally start to spin up Tomcat on a random port. IMHO this is a Spring testing framework bug, but I'm sure they'll have their own opinion on this.
Hope this helped someone.

You could try updating the composer:
sudo composer self-update
If that doest works remove composer files & then use: SSH into terminal & type :
$ cd ~
$ sudo curl -sS https://getcomposer.org/installer | sudo php
$ sudo mv composer.phar /usr/local/bin/composer
$ sudo ln -s /usr/local/bin/composer /usr/bin/composer
If you face an error that says: PHP Fatal error: Uncaught exception 'ErrorException' with message 'proc_open(): fork failed - Cannot allocate memory' in phar
/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
/sbin/mkswap /var/swap.1
/sbin/swapon /var/swap.1
To install package use:
composer global require "package-name"
These are the primitive types in Java:
All the other types are reference types: they reference objects.
This is the first part of the Java tutorial about the basics of the language.
void revealSelection(const ScrollAlignment& = ScrollAlignment::alignCenterIfNeeded, bool revealExtent = false);
This solved my problem. You should select Properties, Right-Click, Source Control and Get Specific Version.
I think you need use List or classes based on that.
For instance,
ArrayList<Integer> integers = new ArrayList<Integer>();
int j;
do{
integers.add(int.nextInt());
j++;
}while( (integers.get(j-1) >= 1) || (integers.get(j-1) <= 100) );
You could read this article for getting more information about how to use that.
This will list Everything (including sub directories) from the directory you specify, in order, and with the attributes. I have spent days looking for something to do this, and I took parts from this entire discussion, and a little of my own, and put it together. ENJOY!!

You can use parents
method with specified .class
selector and check if any of them matches it:
if ($elem.parents('.left').length != 0) {
//someone has this class
}
You can use this function:
function post_unserialize( $key ){
$post_data = array();
$post_data = $_POST[ $key ];
unset($_POST[ $key ]);
parse_str($post_data, $post_data);
$_POST = array_merge($_POST, $post_data);
}
How to use it
$_POST['serialized_data'] = 'var1=1&var2=2&var3=3';
post_unserialize( 'serialized_data' );
Like this:
#include <vector>
// ...
std::vector<std::vector<int>> A(dimension, std::vector<int>(dimension));
(Pre-C++11 you need to leave whitespace between the angled brackets.)
And do not forget the "new" service type (from the k8s docu):
ExternalName: Maps the Service to the contents of the externalName field (e.g. foo.bar.example.com), by returning a CNAME record with its value. No proxying of any kind is set up.
Note: You need either kube-dns version 1.7 or CoreDNS version 0.0.8 or higher to use the ExternalName type.
The API appears to have changed (or at least, it doesn't work for me).
Running the following in the Package Manager Console works as expected:

Node has builtin support for gzip and deflate via the zlib module:
var zlib = require('zlib');
zlib.gunzip(gzipBuffer, function(err, result) {
if(err) return console.error(err);
console.log(result);
});
Edit: You can even pipe
the data directly through e.g. Gunzip
(using request):
var request = require('request'),
zlib = require('zlib'),
fs = require('fs'),
out = fs.createWriteStream('out');
// Fetch http://example.com/foo.gz, gunzip it and store the results in 'out'
request('http://example.com/foo.gz').pipe(zlib.createGunzip()).pipe(out);
For tar archives, there is Isaacs' tar module, which is used by npm.
Edit 2: Updated answer as zlib
doesn't support the zip
format. This will only work for gzip
.
When the compiler compiles the class User
and gets to the MyMessageBox
line, MyMessageBox
has not yet been defined. The compiler has no idea MyMessageBox
exists, so cannot understand the meaning of your class member.
You need to make sure MyMessageBox
is defined before you use it as a member. This is solved by reversing the definition order. However, you have a cyclic dependency: if you move MyMessageBox
above User
, then in the definition of MyMessageBox
the name User
won't be defined!
What you can do is forward declare User
; that is, declare it but don't define it. During compilation, a type that is declared but not defined is called an incomplete type.
Consider the simpler example:
struct foo; // foo is *declared* to be a struct, but that struct is not yet defined
struct bar
{
// this is okay, it's just a pointer;
// we can point to something without knowing how that something is defined
foo* fp;
// likewise, we can form a reference to it
void some_func(foo& fr);
// but this would be an error, as before, because it requires a definition
/* foo fooMember; */
};
struct foo // okay, now define foo!
{
int fooInt;
double fooDouble;
};
void bar::some_func(foo& fr)
{
// now that foo is defined, we can read that reference:
fr.fooInt = 111605;
fr.foDouble = 123.456;
}
By forward declaring User
, MyMessageBox
can still form a pointer or reference to it:
class User; // let the compiler know such a class will be defined
class MyMessageBox
{
public:
// this is ok, no definitions needed yet for User (or Message)
void sendMessage(Message *msg, User *recvr);
Message receiveMessage();
vector<Message>* dataMessageList;
};
class User
{
public:
// also ok, since it's now defined
MyMessageBox dataMsgBox;
};
You cannot do this the other way around: as mentioned, a class member needs to have a definition. (The reason is that the compiler needs to know how much memory User
takes up, and to know that it needs to know the size of its members.) If you were to say:
class MyMessageBox;
class User
{
public:
// size not available! it's an incomplete type
MyMessageBox dataMsgBox;
};
It wouldn't work, since it doesn't know the size yet.
On a side note, this function:
void sendMessage(Message *msg, User *recvr);
Probably shouldn't take either of those by pointer. You can't send a message without a message, nor can you send a message without a user to send it to. And both of those situations are expressible by passing null as an argument to either parameter (null is a perfectly valid pointer value!)
Rather, use a reference (possibly const):
void sendMessage(const Message& msg, User& recvr);
I've used the following code a few times and it works sweet:
$("body").click(function(e){
// Check what has been clicked:
var target = $(e.target);
if(target.is("#target")){
// The target was clicked
// Do something...
}
});
Two things come to mind:
Add dot.exe to your path. right click my computer > advanced system settings > environment variables > high light 'path' > edit then append everything in the quotes to path ";C:\Program Files (x86)\Graphviz2.34\bin\" depending on where you installed Graphviz ofcourse.Then restart the python shell and type.
import pydot pydot.find_graphviz() Make sure there is a slash after 'bin' so it gets everything from inside the folder, I tried with out the slash and the above code returned nothing, however after adding the slash it returned the graphviz executables it needed and their paths.
document.write()
doesn't work with XHTML. It's executed after the page has finished loading and does nothing more than write out a string of HTML.
Since the actual in-memory representation of HTML is the DOM, the best way to update a given page is to manipulate the DOM directly.
The way you'd go about doing this would be to programmatically create your nodes and then attach them to an existing place in the DOM. For [purposes of a contrived] example, assuming that I've got a div
element maintaining an ID
attribute of "header," then I could introduce some dynamic text by doing this:
// create my text
var sHeader = document.createTextNode('Hello world!');
// create an element for the text and append it
var spanHeader = document.createElement('span');
spanHeader.appendChild(sHeader);
// grab a reference to the div header
var divHeader = document.getElementById('header');
// append the new element to the header
divHeader.appendChild(spanHeader);
msg * /time:0 /w Hello everybody!
This message waits forever until OK is clicked (it lasts only one minute by default) and works fine in Windows 8.1
If you are okay with just having IE open the JSON into a notepad, you can change your system's default program for .json files to Notepad.
To do this, create or find a .json file, right mouse click, and select "Open With" or "Choose Default Program."
This might come in handy if you by chance want to use Internet Explorer but your IT company wont let you edit your registry. Otherwise, I recommend the above answers.

Although ANSI C does not have this mechanism, it is possible to use itoa() as a shortcut:
char buffer [33];
itoa (i,buffer,2);
printf ("binary: %s\n",buffer);
Here's the origin:
It is non-standard C, but K&R mentioned the implementation in the C book, so it should be quite common. It should be in stdlib.h.
The compiler is complaining because you currently have the 'if(exist)' block inside of your for loop. It needs to be outside of it.
for(int i=0;i<this.customers.size();i++){
if(this.customers.get(i).getId() == id){
exist=true;
break;
}
}
if(exist) {
return this.customers.get(id);
} else {
return this.customers.get(id);
}
That being said, there are better ways to perform this search. Personally, if I were using an ArrayList, my solution would look like the one that Jon Skeet has posted.
Create a button with an id share and add the following code snippet.
share.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
String shareBody = "Your body here";
String shareSub = "Your subject here";
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, shareSub);
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(sharingIntent, "Share using"));
}
});
The above code snippet will open the share chooser on share button click action. However, note...The share code snippet might not output very good results using emulator. For actual results, run the code snippet on android device to get the real results.
Every class or interface can be used as a type in TypeScript.
const date = new Date();
will already know about the date
type definition as Date
is an internal TypeScript object referenced by the DateConstructor interface.
And for the constructor you used, it is defined as:
interface DateConstructor {
new(): Date;
...
}
To make it more explicit, you can use:
const date: Date = new Date();
You might be missing the type definitions though, the Date
is coming for my example from the ES6 lib, and in my tsconfig.json
I have defined:
"compilerOptions": {
"target": "ES6",
"lib": [
"es6",
"dom"
],
You might adapt these settings to target your wanted version of JavaScript.

Hi , You can use this in your .ts file :
first import your service in this .ts file:
import { Your_Service_Name } from './path_To_Your_Service_Name';
Then in the same file you can add providers: [Your_Service_Name]
:
@Component({
selector: 'my-app',
providers: [Your_Service_Name],
template: `
<h1>Hello World</h1> `
})
maybe you are looking for
