use this
System.Configuration.ConfigurationSettings.AppSettings.Get("Keyname")
The issue, I believe, is that the Json action result is intended to take an object (your model) and create an HTTP response with content as the JSON-formatted data from your model object.
What you are passing to the controller's Json method, though, is a JSON-formatted string object, so it is "serializing" the string object to JSON, which is why the content of the HTTP response is surrounded by double-quotes (I'm assuming that is the problem).
I think you can look into using the Content action result as an alternative to the Json action result, since you essentially already have the raw content for the HTTP response available.
return this.Content(returntext, "application/json");
// not sure off-hand if you should also specify "charset=utf-8" here,
// or if that is done automatically
Another alternative would be to deserialize the JSON result from the service into an object and then pass that object to the controller's Json method, but the disadvantage there is that you would be de-serializing and then re-serializing the data, which may be unnecessary for your purposes.
First, I don't understand why you are adding all the keys and values count times, Index is never used.
I tried this example :
var source = new BindingSource();
List<MyStruct> list = new List<MyStruct> { new MyStruct("fff", "b"), new MyStruct("c","d") };
source.DataSource = list;
grid.DataSource = source;
and that work pretty well, I get two columns with the correct names. MyStruct type exposes properties that the binding mechanism can use.
class MyStruct
{
public string Name { get; set; }
public string Adres { get; set; }
public MyStruct(string name, string adress)
{
Name = name;
Adres = adress;
}
}
Try to build a type that takes one key and value, and add it one by one. Hope this helps.
An XSD is included with EntLib 5, and is installed in the Visual Studio schema directory. In my case, it could be found at:
C:\Program Files (x86)\Microsoft Visual Studio 10.0\Xml\Schemas\EnterpriseLibrary.Configuration.xsd
It is worth repeating that these "Error List" "Messages" ("Could not find schema information for the element") are only visible when you open the app.config file. If you "Close All Documents" and compile... no messages will be reported.
The reason is simple, your call to ConfigurationSettings.AppSettings
is not returning the required config file. Please try any of the following ways:
ConfigurationManager.OpenExeConfiguration(Assembly.GetExecutingAssembly().Location).AppSettings["StartingMonthColumn"]
Hope this helps
thanks for pointing me in the right direction. I found user.config located at this monstrosity: c:\users\USER\AppData\Local\COMPANY\APPLICATION.exe_Url_LOOKSLIKESOMEKINDOFHASH\VERSION\user.config.
I had to uprev the version on my application and all the settings seemed to have vanished. application created a new folder with the new version and used the default settings. took forever to find where the file was stored, but then it was a simple copy and paste to get the settings to the new version.
You can also refresh the configuration in it's entirety:
ConnectionStringSettings importToConnectionString = currentConfiguration.ConnectionStrings.ConnectionStrings[newName];
if (importToConnectionString == null)
{
importToConnectionString = new ConnectionStringSettings();
importToConnectionString.ConnectionString = importFromConnectionString.ConnectionString;
importToConnectionString.ProviderName = importFromConnectionString.ProviderName;
importToConnectionString.Name = newName;
currentConfiguration.ConnectionStrings.ConnectionStrings.Add(importToConnectionString);
}
else
{
importToConnectionString.ConnectionString = importFromConnectionString.ConnectionString;
importToConnectionString.ProviderName = importFromConnectionString.ProviderName;
}
Properties.Settings.Default.Reload();
this is easily achievable with RegExp!
const str = 'Hello RegEx!';
const index = 11;
const replaceWith = 'p';
//'Hello RegEx!'.replace(/^(.{11})(.)/, `$1p`);
str.replace(new RegExp(`^(.{${ index }})(.)`), `$1${ replaceWith }`);
//< "Hello RegExp"
Good question.
@@IDENTITY
: returns the last identity value generated on your SQL connection (SPID). Most of the time it will be what you want, but sometimes it isn't (like when a trigger is fired in response to an INSERT
, and the trigger executes another INSERT
statement).
SCOPE_IDENTITY()
: returns the last identity value generated in the current scope (i.e. stored procedure, trigger, function, etc).
IDENT_CURRENT()
: returns the last identity value for a specific table. Don't use this to get the identity value from an INSERT
, it's subject to race conditions (i.e. multiple connections inserting rows on the same table).
IDENTITY()
: used when declaring a column in a table as an identity column.
For more reference, see: http://msdn.microsoft.com/en-us/library/ms187342.aspx.
To summarize: if you are inserting rows, and you want to know the value of the identity column for the row you just inserted, always use SCOPE_IDENTITY()
.
If you want to combine some activities with actionbar and others not, you should use the base theme have actionbar enabled and then create a sub theme that you gonna use it on activities that don't require actionbar
For example you can use a sub style like this
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
While the base theme extends say
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
and then use the non actionbar theme in the AndroidManifest File within the activity tag say
<activity
android:name="com.example.NonActionBarActivity"
android:theme="@style/AppTheme.NoActionBar"
you must apply this to each individual activity that don't need actionbar so if your project requires fewer action bar activities than non, then it's better to apply this on the base theme level
Here is the consolidated list order by my preference.
Using apache commons
import org.apache.commons.io.FilenameUtils;
String fileNameWithoutExt = FilenameUtils.getBaseName(fileName);
OR
String fileNameWithOutExt = FilenameUtils.removeExtension(fileName);
Using Google Guava (If u already using it)
import com.google.common.io.Files;
String fileNameWithOutExt = Files.getNameWithoutExtension(fileName);
Or using Core Java
1)
String fileName = file.getName();
int pos = fileName.lastIndexOf(".");
if (pos > 0 && pos < (fileName.length() - 1)) { // If '.' is not the first or last character.
fileName = fileName.substring(0, pos);
}
if (fileName.indexOf(".") > 0) {
return fileName.substring(0, fileName.lastIndexOf("."));
} else {
return fileName;
}
private static final Pattern ext = Pattern.compile("(?<=.)\\.[^.]+$");
public static String getFileNameWithoutExtension(File file) {
return ext.matcher(file.getName()).replaceAll("");
}
Liferay API
import com.liferay.portal.kernel.util.FileUtil;
String fileName = FileUtil.stripExtension(file.getName());
typedef struct Freqamp{
double freq;
double amp;
}FREQAMP;
bool struct_cmp_by_freq(FREQAMP a, FREQAMP b)
{
return a.freq < b.freq;
}
main()
{
vector <FREQAMP> temp;
FREQAMP freqAMP;
freqAMP.freq = 330;
freqAMP.amp = 117.56;
temp.push_back(freqAMP);
freqAMP.freq = 450;
freqAMP.amp = 99.56;
temp.push_back(freqAMP);
freqAMP.freq = 110;
freqAMP.amp = 106.56;
temp.push_back(freqAMP);
sort(temp.begin(),temp.end(), struct_cmp_by_freq);
}
if compare is false, it will do "swap".
According to your package.json, you're using Angular 8.3, but you've imported angular/cdk v9. You can downgrade your angular/cdk version or you can upgrade your Angular version to v9 by running:
ng update @angular/core @angular/cli
That will update your local angular version to 9. Then, just to sync material, run:
ng update @angular/material
With CMake, it's generally recommended to do an "out of source" build. Create your CMakeLists.txt
in the root of your project. Then from the root of your project:
mkdir Release
cd Release
cmake -DCMAKE_BUILD_TYPE=Release ..
make
And for Debug
(again from the root of your project):
mkdir Debug
cd Debug
cmake -DCMAKE_BUILD_TYPE=Debug ..
make
Release
/ Debug
will add the appropriate flags for your compiler. There are also RelWithDebInfo
and MinSizeRel
build configurations.
You can modify/add to the flags by specifying a toolchain file in which you can add CMAKE_<LANG>_FLAGS_<CONFIG>_INIT
variables, e.g.:
set(CMAKE_CXX_FLAGS_DEBUG_INIT "-Wall")
set(CMAKE_CXX_FLAGS_RELEASE_INIT "-Wall")
See CMAKE_BUILD_TYPE for more details.
As for your third question, I'm not sure what you are asking exactly. CMake should automatically detect and use the compiler appropriate for your different source files.

You could use the INDIRECT function. This takes a string and converts it into a range
More info here
=INDIRECT("K"&A2)
But it's preferable to use INDEX as it is less volatile.
=INDEX(K:K,A2)
This returns a value or the reference to a value from within a table or range

Put either function into cell B2 and fill down.
I would use JPA's constructor expression feature. See also following answer:

Following the example in the question, it would be something like this.

Check out the documentation for numpy.sum
, paying particular attention to the axis
parameter. To sum over columns:
>>> import numpy as np
>>> a = np.arange(12).reshape(4,3)
>>> a.sum(axis=0)
array([18, 22, 26])
Or, to sum over rows:
>>> a.sum(axis=1)
array([ 3, 12, 21, 30])
Other aggregate functions, like numpy.mean
, numpy.cumsum
and numpy.std
, e.g., also take the axis
parameter.
From the Tentative Numpy Tutorial:
Many unary operations, such as computing the sum of all the elements in the array, are implemented as methods of the
ndarray
class. By default, these operations apply to the array as though it were a list of numbers, regardless of its shape. However, by specifying theaxis
parameter you can apply an operation along the specified axis of an array:
In controller:
function innerItem($scope, $element){
var jQueryInnerItem = $($element);
}
Even though adding a text view to the toolbar can solve the problem of the restriction of title styling, there is an issue with it. Since we are not adding it to a layout, we do not have too much control over its width. We can either use wrap_content or match_parent.
Now consider a scenario where we have a searchView as a button on the right edge of the toolbar. If the title contents are more, it will go on top of the button obscuring it. There is no way of controlling this short of setting a width to the label and is something you don't want to do if you want to have a responsive design.
So, here is a solution that worked for me which is slightly different from adding a textview to the toolbar. Instead of that, add the toolbar and text view to a relative layout and ensure that the text view is on top of the toolbar. Then we can use appropriate margins and make sure the text view shows up where we want it to show up.
Make sure you set the toolbar to not show the title.
Here is the XML for this solution:
<RelativeLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary">
<android.support.v7.widget.Toolbar
android:theme="@style/ThemeOverlay.AppCompat.Dark"
android:id="@+id/activity_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:titleTextAppearance="@style/AppTheme.TitleTextView"
android:layout_marginRight="40dp"
android:layoutMode="clipBounds">
<android.support.v7.widget.SearchView
android:id="@+id/search_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:layout_centerVertical="true"
android:layout_alignParentRight="true"
android:foregroundTint="@color/white" />
</android.support.v7.widget.Toolbar>
<TextView
android:id="@+id/toolbar_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginRight="90dp"
android:text="@string/app_name"
android:textSize="@dimen/title_text_size"
android:textColor="@color/white"
android:lines="1"

You can create a new model to Deserialize your Json CustomerJson
:
public class CustomerJson
{
[JsonProperty("customer")]
public Customer Customer { get; set; }
}
public class Customer
{
[JsonProperty("first_name")]
public string Firstname { get; set; }
[JsonProperty("last_name")]
public string Lastname { get; set; }
...
}
And you can deserialize your json easily :
JsonConvert.DeserializeObject<List<CustomerJson>>(json);
Hope it helps !

You don't need a custom script like pyfunc's answer for OSX (at least on mavericks). In Idle click on Idle -> Preferences -> Keys, locate "history-next" and "history-previous", and either leave them with their default keyboard shortcut or assign "up arrow" and "down arrow" per typical expected terminal behavior.
This is on Idle 2.7 on OSX Mavericks.
the core functions are getBytes(String charset)
and new String(byte[] data)
. you can use these functions to do UTF-8 decoding.
UTF-8 decoding actually is a string to string conversion, the intermediate buffer is a byte array. since the target is an UTF-8 string, so the only parameter for new String()
is the byte array, which calling is equal to new String(bytes, "UTF-8")
Then the key is the parameter for input encoded string to get internal byte array, which you should know beforehand. If you don't, guess the most possible one, "ISO-8859-1" is a good guess for English user.
The decoding sentence should be
String decoded = new String(encoded.getBytes("ISO-8859-1"));
which(df==my.val, arr.ind=TRUE)
Here is the same problem.
You need to set table-layout:fixed
and a suitable width on the table element, as well as overflow:hidden
and white-space: nowrap
on the table cells.
The width of the table has to be the same (or smaller) than the fixed width cell(s).
With one fixed width column:
* {
box-sizing: border-box;
}
table {
table-layout: fixed;
border-collapse: collapse;
width: 100%;
max-width: 100px;
}
td {
background: #F00;
padding: 20px;
overflow: hidden;
white-space: nowrap;
width: 100px;

I prefer using singular form for both simplicity and consistency.
For example, considering the following url:
/customer/1
I will treat customer as customer collection, but for simplicity, the collection part is removed.
Another example:
/equipment/1
In this case, equipments is not the correct plural form. So treating it as a equipment collection and removing collection for simplicity makes it consistent with the customer case.
There were 8 other signals they came up with first.
It is not allocating memory at assignment of value 12 to integer pointer. Therefore it crashes, because it's not finding any memory.
You can try this:
#include<stdio.h>
#include<stdlib.h>
int *fun();
int main()
{
int *ptr;
ptr=fun();
printf("\n\t\t%d\n",*ptr);
}
int *fun()
{
int ptr;
ptr=12;
return(&ptr);
}
Caling .Value2
is an expensive operation because it's a COM-interop call. I would instead read the entire range into an array and then loop through the array:
object[,] data = Range.Value2;
// Create new Column in DataTable
for (int cCnt = 1; cCnt <= Range.Columns.Count; cCnt++)
{
textBox3.Text = cCnt.ToString();
var Column = new DataColumn();
Column.DataType = System.Type.GetType("System.String");
Column.ColumnName = cCnt.ToString();
DT.Columns.Add(Column);
// Create row for Data Table
for (int rCnt = 1; rCnt <= Range.Rows.Count; rCnt++)
{
textBox2.Text = rCnt.ToString();
string CellVal = String.Empty;
try
{
cellVal = (string)(data[rCnt, cCnt]);
}
catch (Microsoft.CSharp.RuntimeBinder.RuntimeBinderException)
{
ConvertVal = (double)(data[rCnt, cCnt]);
cellVal = ConvertVal.ToString();
}
DataRow Row;
// Add to the DataTable
if (cCnt == 1)
{
Row = DT.NewRow();
Row[cCnt.ToString()] = cellVal;
DT.Rows.Add(Row);
}
else
{
Row = DT.Rows[rCnt + 1];
Row[cCnt.ToString()] = cellVal;
}
}
}
This is a simple way.
<div class="row">
<div class="col-md-6 mx-auto">
<p>My text</p>
</div>
</div>
The number 6 controls the width of the column.
Vector
synchronizes on each individual operation. That's almost never what you want to do.
Generally you want to synchronize a whole sequence of operations. Synchronizing individual operations is both less safe (if you iterate over a Vector
, for instance, you still need to take out a lock to avoid anyone else changing the collection at the same time, which would cause a ConcurrentModificationException
in the iterating thread) but also slower (why take out a lock repeatedly when once will be enough)?
Of course, it also has the overhead of locking even when you don't need to.
Basically, it's a very flawed approach to synchronization in most situations. As Mr Brian Henk pointed out, you can decorate a collection using the calls such as Collections.synchronizedList
- the fact that Vector
combines both the "resized array" collection implementation with the "synchronize every operation" bit is another example of poor design; the decoration approach gives cleaner separation of concerns.
As for a Stack
equivalent - I'd look at Deque
/ArrayDeque
to start with.
SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd");
sdf.format(new Date());
This should do the trick
This is a tool to open Java class file binaries, view their internal structure, modify portions of it if required and save the class file back. It also generates readable reports similar to the javap utility. Easy to use Java Swing GUI. The user interface tries to display as much detail as possible and tries to present a structure as close as the actual Java class file structure. At the same time ease of use and class file consistency while doing modifications is also stressed. For example, when a method is deleted, the associated constant pool entry will also be deleted if it is no longer referenced. In built verifier checks changes before saving the file. This tool has been used by people learning Java class file internals. This tool has also been used to do quick modifications in class files when the source code is not available." this is a quote from the website.

I solved mine by using an Import directive under my Page directive. You may also want to add the namespace to your Inherits attribute of your Page directive.
Since it appears that your default namespace is "stman.Members", try:
<%@ Page Title="" Language="C#" MasterPageFile="~/Members/Members.master" AutoEventWireup="true" CodeFile="Jobs.aspx.cs" Inherits="stman.Members.Members_Jobs" %>
<%@ Import Namespace="stman.Members"%>
Additionally, data that I wanted to pass between aspx.cs and aspx, I put inside a static class inside the namespace. That static class was available to move data around in the name space and no longer has a "not in context" error.
Add Content-Type
: application/json
and Accept
: application/json
The accepted answer doesn't cut it because if a user de-selects a row the list is not updated accordingly.
Here is what I suggest instead:
Private Sub CommandButton2_Click()
Dim lItem As Long
For lItem = 0 To ListBox1.ListCount - 1
If ListBox1.Selected(lItem) = True Then
MsgBox(ListBox1.List(lItem))
End If
Next
End Sub

Apart from the DATEDIFF you can also use the TIMEDIFF function or the TIMESTAMPDIFF.
EXAMPLE
SET @date1 = '2010-10-11 12:15:35', @date2 = '2010-10-10 00:00:00';
SELECT
TIMEDIFF(@date1, @date2) AS 'TIMEDIFF',
TIMESTAMPDIFF(hour, @date1, @date2) AS 'Hours',
TIMESTAMPDIFF(minute, @date1, @date2) AS 'Minutes',
TIMESTAMPDIFF(second, @date1, @date2) AS 'Seconds';
RESULTS
TIMEDIFF : 36:15:35
Hours : -36
Minutes : -2175
Seconds : -130535

I faced the same error when I trying to open postgresql on mac
psql: FATAL: database "user" does not exist
I found this simple command to solve it:
method1
$ createdb --owner=postgres --encoding=utf8 user
and type
psql
Method 2:
psql -d postgres
Try this code:
final File f = new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation().getPath());
replace 'MyClass
' with your class containing the main method.
Alternatively you can also use
System.getProperty("java.class.path")
Above mentioned System property provides
Path used to find directories and JAR archives containing class files. Elements of the class path are separated by a platform-specific character specified in the path.separator property.
OK - so this issue has been driving me crazy - v 6.3.6 on Ubuntu Linux. None of the above solutions worked for me. Connecting to localhost mysql server previously always worked fine. Connecting to remote server always timed out - after about 60 seconds, sometimes after less time, sometimes more.
What finally worked for me was upgrading Workbench to 6.3.9 - no more dropped connections.

like what are mentioned in the previous posts. However the process monitor said that this registry is access denied.
So I opened regedit and found that registry key and I could not open it. It says I have no permission to see it.
SO I had to change its permission:
I found that this registry key has several sub keys, however you have to restart regedit to see them.
By seeing which other registry keys are access denied in process monitor , I knew that VS2013 will specifically deal with these subkeys which are ACCESS DENIED also: 06181 0bcad
and these subkeys should be changed their permissions as well like above.
After making these permission changes everything worked well.
The same thing has been done to Microsoft visual studio 2010 because an error in the license as well and the solution worked well.
UPDATE : It turned out that starting visual studio as administrator solved this issue without this registry massage. Seems that this happened to my pc after changing the 'required password to login' removed in the user settings. (I wanted to let the pc start running without any password after restart from a crash or anything else). This made a lot of programs not able to write into some folders like temp folders unless I start the application as admin. Even printing from excel would not work, if excel is not started as admin.
Use the enumerate()
function to generate the index along with the elements of the sequence you are looping over:
for index, w in enumerate(loopme):
print "CURRENT WORD IS", w, "AT CHARACTER", index
To help debug, and make your code better, do this:
private void processLine(String[] strings) {
Integer[] intarray=new Integer[strings.length];
int i=0;
for(String str:strings){
try {
intarray[i]=Integer.parseInt(str);
i++;
} catch (NumberFormatException e) {
throw new IllegalArgumentException("Not a number: " + str + " at index " + i, e);
}
}
}
Also, from a code neatness point, you could reduce the lines by doing this:
for (String str : strings)
intarray[i++] = Integer.parseInt(str);
Edit: Harhar is now open source. I have updated the URL below.
If you use an Avalanche load generator, you can use Harhar to replay a HAR file at very high load: https://acastaner.github.io/harhar/
This tool handles the "content" you use when you "Save as HAR with content."
You can use Explicit wait or Fluent Wait
Example of Explicit Wait -
WebDriverWait wait = new WebDriverWait(WebDriverRefrence,20);
WebElement aboutMe;
aboutMe= wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("about_me")));
Example of Fluent Wait -
Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
.withTimeout(20, TimeUnit.SECONDS)
.pollingEvery(5, TimeUnit.SECONDS)
.ignoring(NoSuchElementException.class);
WebElement aboutMe= wait.until(new Function<WebDriver, WebElement>() {
public WebElement apply(WebDriver driver) {
return driver.findElement(By.id("about_me"));
}
});

Your problem is that Python is looking in the Python directory for this file and not finding it. You must specify that you are talking about the directory that you are in and not the Python one.
To do this you change this:
from application.app.folder.file import func_name
to this:
from .application.app.folder.file import func_name
By adding the dot you are saying look in this folder for the application folder instead of looking in the Python directory.
Using the 'WipeWorkspace' extension seems to work as well. It requires the longer form:
checkout([
$class: 'GitSCM',
branches: scm.branches,
extensions: scm.extensions + [[$class: 'WipeWorkspace']],
userRemoteConfigs: scm.userRemoteConfigs
])

An unmodifiable map may still change. It is only a view on a modifiable map, and changes in the backing map will be visible through the unmodifiable map. The unmodifiable map only prevents modifications for those who only have the reference to the unmodifiable view:
Map<String, String> realMap = new HashMap<String, String>();
realMap.put("A", "B");
Map<String, String> unmodifiableMap = Collections.unmodifiableMap(realMap);
// This is not possible: It would throw an
// UnsupportedOperationException
//unmodifiableMap.put("C", "D");
// This is still possible:
realMap.put("E", "F");
// The change in the "realMap" is now also visible
// in the "unmodifiableMap". So the unmodifiableMap
// has changed after it has been created.
unmodifiableMap.get("E"); // Will return "F".
In contrast to that, the ImmutableMap of Guava is really immutable: It is a true copy of a given map, and nobody may modify this ImmutableMap in any way.
Update:
As pointed out in a comment, an immutable map can also be created with the standard API using
Map<String, String> immutableMap =
Collections.unmodifiableMap(new LinkedHashMap<String, String>(realMap));
This will create an unmodifiable view on a true copy of the given map, and thus nicely emulates the characteristics of the ImmutableMap
without having to add the dependency to Guava.

Since PyYAML's yaml.load()
function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:
import yaml
with open('tree.yaml', 'r') as f:
doc = yaml.load(f)
To access branch1 text
you would use:
txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"
because, in your YAML document, the value of the branch1
key is under the treeroot
key.
One Google search later we've learned that you can set the entire plotting device background color as Owen indicates. If you just want the plotting region altered, you have to do something like what is outlined in that R-Help thread:
plot(df)
rect(par("usr")[1],par("usr")[3],par("usr")[2],par("usr")[4],col = "gray")
points(df)
The barplot
function has an add
parameter that you'll likely need to use.
convert(varchar(7), <date_field>, 120)
because 120 results in 'yyyy-MM-dd' which is varchar(10)
using varchar(7) will display only year and month
example:
select convert(varchar(7), <date_field>, 120), COUNT(*)
from <some_table>
group by convert(varchar(7), <date_field>, 120)
order by 1
You can use the mktime(hour, minute, seconds, month, day, year) function
$paymentDate = mktime(0, 0, 0, date('m'), date('d'), date('Y'));
$contractDateBegin = mktime(0, 0, 0, 1, 1, 2001);
$contractDateEnd = mktime(0, 0, 0, 1, 1, 2012);
if ($paymentDate >= $contractDateBegin && $paymentDate <= $contractDateEnd){
echo "is between";
}else{
echo "NO GO!";
}
This question needed a more up-to-date answer, with sources. This is what actually works (though you don't have to take my word for it):
// Storing this jQuery object outside of the event callback
// prevents jQuery from having to search the DOM for it again
// every time an event is fired.
var $myButton = $("#buttonID")
// input :: for all modern browsers [1]
// selectionchange :: for IE9 [2]
// propertychange :: for <IE9 [3]
$('#textareaID').on('input selectionchange propertychange', function() {
// This is the correct way to enable/disabled a button in jQuery [4]
$myButton.prop('disabled', this.value.length === 0)
}
1: https://developer.mozilla.org/en-US/docs/Web/Events/input#Browser_compatibility
2: oninput in IE9 doesn't fire when we hit BACKSPACE / DEL / do CUT

BUT, for a more global solution that you can use throughout your project, I recommend using the textchange jQuery plugin to gain a new, cross-browser compatible textchange
event. It was developed by the same person who implemented the equivalent onChange
event for Facebook's ReactJS, which they use for nearly their entire website. And I think it's safe to say, if it's a robust enough solution for Facebook, it's probably robust enough for you. :-)
UPDATE: If you happen to need features like drag and drop support in Internet Explorer, you may instead want to check out pandell
's more recently updated fork of jquery-splendid-textchange
.
Here Blank mean what you are meaning.
A line contains full of whitespaces or a line contains nothing.
If you want to match a line which contains nothing then use '/^$/'.
The solution for me (openSUSE Leap 42.3, KDE) was to rename the folder ~/.gnupg
which apparently contained the cached keys and profiles.
After KDE logout/logon the ssh-add/agent is running again and the folder is created from scratch, but the old keys are all gone.
I didn't have success with the other approaches.
I'd suggest you have a look at media-queries. This is a useful new addition to CSS that really makes so much sense, you'd wonder why this wasn't implemented waaay earlier. Basically it allows you to target browser attributes (such as max and min-widths) directly via CSS and branch your layout code from there. Similar to creating a print stylesheet, you can create your desktop and mobile layouts in parallel in the same file, which kicks ass for development.
Here is a very good tutorial on how to build a custom context menu with a full working code example (without JQuery and other libraries).
You can also find their demo code on GitHub.
They give a detailed step-by-step explanation that you can follow along to build your own right-click context menu (including html, css and javascript code) and summarize it at the end by giving the complete example code.
You can follow along easily and adapt it to your own needs. And there is no need for JQuery or other libraries.
This is how their example menu code looks like:
<nav id="context-menu" class="context-menu">
<ul class="context-menu__items">
<li class="context-menu__item">
<a href="#" class="context-menu__link" data-action="View"><i class="fa fa-eye"></i> View Task</a>
</li>
<li class="context-menu__item">
<a href="#" class="context-menu__link" data-action="Edit"><i class="fa fa-edit"></i> Edit Task</a>
</li>
<li class="context-menu__item">
<a href="#" class="context-menu__link" data-action="Delete"><i class="fa fa-times"></i> Delete Task</a>
</li>
</ul>
</nav>
Maybe you can use the [Integer] data annotation (If you use the DataAnnotationsExtensions http://dataannotationsextensions.org/) . However, this wil only check if the value is an integer, nót if it is filled in (So you may also need the [Required] attribute).
If you enable Unobtrusive Validation it will validate it clientside, but you should also use Modelstate.Valid in your POST action to decline it in case people have Javascript disabled.
Calling this method does not cause the delegate to receive a
tableView:willSelectRowAtIndexPath:
ortableView:didSelectRowAtIndexPath:
message, nor does it sendUITableViewSelectionDidChangeNotification
notifications to observers.
What I would do is:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[self doSomethingWithRowAtIndexPath:indexPath];
}
And then, from where you wanted to call selectRowAtIndexPath, you instead call doSomethingWithRowAtIndexPath. On top of that, you can additionally also call selectRowAtIndexPath if you want the UI feedback to happen.
slf4j is only an API. You should have a concrete implementation (for example log4j). This concrete implementation has a config file which tells you where to store the logs.
When slf4j catches a log messages with a logger, it is given to an appender which decides what to do with the message. By default, the ConsoleAppender displays the message in the console.
The default configuration file is :
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
<Appenders>
<!-- By default => console -->
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
</Console>
</Appenders>
<Loggers>
<Root level="error">
<AppenderRef ref="Console"/>
</Root>
</Loggers>
</Configuration>
If you put a configuration file available in the classpath, then your concrete implementation (in your case, log4j) will find and use it. See Log4J documentation.
Example of file appender :
<Appenders>
<File name="File" fileName="${filename}">
<PatternLayout>
<pattern>%d %p %C{1.} [%t] %m%n</pattern>
</PatternLayout>
</File>
...
</Appenders>
Complete example with a file appender :
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
<Appenders>
<File name="File" fileName="${filename}">
<PatternLayout>
<pattern>%d %p %C{1.} [%t] %m%n</pattern>
</PatternLayout>
</File>
</Appenders>
<Loggers>
<Root level="error">
<AppenderRef ref="File"/>
</Root>
</Loggers>
</Configuration>

Steps to install curl in windows
Install cURL on Windows
There are 4 steps to follow to get cURL installed on Windows.
Step 1 and Step 2 is to install SSL library. Step 3 is to install cURL. Step 4 is to install a recent certificate
Step One: Install Visual C++ 2008 Redistributables
From https://www.microsoft.com/en-za/download/details.aspx?id=29 For 64bit systems Visual C++ 2008 Redistributables (x64) For 32bit systems Visual C++ 2008 Redistributables (x32)
Step Two: Install Win(32/64) OpenSSL v1.0.0k Light
From http://www.shininglightpro.com/products/Win32OpenSSL.html For 64bit systems Win64 OpenSSL v1.0.0k Light For 32bit systems Win32 OpenSSL v1.0.0k Light
Step Three: Install cURL
Depending on if your system is 32 or 64 bit, download the corresponding** curl.exe.** For example, go to the Win64 - Generic section and download the Win64 binary with SSL support (the one where SSL is not crossed out). Visit http://curl.haxx.se/download.html
Copy curl.exe to C:\Windows\System32
Step Four: Install Recent Certificates
Do not skip this step. Download a recent copy of valid CERT files from https://curl.haxx.se/ca/cacert.pem Copy it to the same folder as you placed curl.exe (C:\Windows\System32) and rename it as curl-ca-bundle.crt
If you have already installed curl
or after doing the above steps, add the directory where it's installed to the windows path:
1 - From the Desktop, right-click My Computer and click Properties.
2 - Click Advanced System Settings .
3 - In the System Properties window click the Environment Variables button.
4 - Select Path and click Edit.
5 - Append ;c:\path to curl directory at the end.
5 - Click OK.
6 - Close and re-open the command prompt
jupyter notebook --notebook-dir=%WORKING_DIR%,
where %WORKING_DIR% (H:\data\ML) - directory where you're going to work
It is the simplest one-line command way, IMHO

CSS.
Assuming the MyEjbProject is not another Maven Project you own or want to build with maven, you could use system dependencies to link to the existing jar file of the project like so
<project>
...
<dependencies>
<dependency>
<groupId>yourgroup</groupId>
<artifactId>myejbproject</artifactId>
<version>2.0</version>
<scope>system</scope>
<systemPath>path/to/myejbproject.jar</systemPath>
</dependency>
</dependencies>
...
</project>
That said it is usually the better (and preferred way) to install the package to the repository either by making it a maven project and building it or installing it the way you already seem to do.
If they are, however, dependent on each other, you can always create a separate parent project (has to be a "pom" project) declaring the two other projects as its "modules". (The child projects would not have to declare the third project as their parent). As a consequence you'd get a new directory for the new parent project, where you'd also quite probably put the two independent projects like this:
parent
|- pom.xml
|- MyEJBProject
| `- pom.xml
`- MyWarProject
`- pom.xml
The parent project would get a "modules" section to name all the child modules. The aggregator would then use the dependencies in the child modules to actually find out the order in which the projects are to be built)
<project>
...
<artifactId>myparentproject</artifactId>
<groupId>...</groupId>
<version>...</version>
<packaging>pom</packaging>
...
<modules>
<module>MyEJBModule</module>
<module>MyWarModule</module>
</modules>
...
</project>
That way the projects can relate to each other but (once they are installed in the local repository) still be used independently as artifacts in other projects
Finally, if your projects are not in related directories, you might try to give them as relative modules:
filesystem
|- mywarproject
| `pom.xml
|- myejbproject
| `pom.xml
`- parent
`pom.xml
now you could just do this (worked in maven 2, just tried it):
<!--parent-->
<project>
<modules>
<module>../mywarproject</module>
<module>../myejbproject</module>
</modules>
</project>
I will start my answer saying that most of previous answers were perfectly good answers at the time of writing them. So, thank you to them who wrote them.
Now, you can also use String Interpolation for same solution.
Edit: Adding this explanation after receiving a perfectively valid constructive comment from Heretic Monkey. I have preferred to use .ToString whenever I had need to convert an integer to string and not add the result to any other string. And, I have preferred to use interpolation whenever I had need to combine string(s) and an integer, like in below examples.
i.ToString("00")
01
i.ToString("000")
001
i.ToString("0000")
0001
$"Prefix_{i:00}"
Prefix_01
$"Prefix_{i:000}"
Prefix_001
$"Prefix_{i:0000}_Suffix"
Prefix_0001_Suffix
@VonC already gave a very nice answer, but for completeness here is a little script I have been using---and which also nukes any errand Docker processes should you have some:
#!/bin/bash
imgs=$(docker images | awk '/<none>/ { print $3 }')
if [ "${imgs}" != "" ]; then
echo docker rmi ${imgs}
docker rmi ${imgs}
else
echo "No images to remove"
fi
procs=$(docker ps -a -q --no-trunc)
if [ "${procs}" != "" ]; then
echo docker rm ${procs}
docker rm ${procs}
else
echo "No processes to purge"
fi
In my Controller, I merely added an HttpServletResponse parameter and manually added the headers, no filter or intercept required and it works fine:
httpServletResponse.setHeader("Access-Control-Allow-Origin", "*");
httpServletResponse.setHeader("Access-Control-Allow-Methods", "GET, OPTIONS");
httpServletResponse.setHeader("Access-Control-Allow-Headers","Origin, X-Requested-With, Content-Type, Accept, X-Auth-Token, X-Csrf-Token, WWW-Authenticate, Authorization");
httpServletResponse.setHeader("Access-Control-Allow-Credentials", "false");
httpServletResponse.setHeader("Access-Control-Max-Age", "3600");
There are at least three ways to disable the use of unobtrusive JavaScript for client-side validation:
<configuration>
<appSettings>
<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
</appSettings>
</configuration>
System.Web.UI.ValidationSettings.UnobtrusiveValidationMode
static property to System.Web.UI.UnobtrusiveValidationMode.None
System.Web.UI.Page.UnobtrusiveValidationMode
instance property to System.Web.UI.UnobtrusiveValidationMode.None
To disable the functionality on a per page basis, I prefer to set the Page.UnobtrusiveValidationMode
property using the page directive:
<%@ Page Language="C#" UnobtrusiveValidationMode="None" %>
I am not sure but you can try intialising handler to null in onDestroy()
You need one project per language. I'm quite confident I saw a tool that merged assemblies, if you find that tool you should be good to go. If you need to use both languages in the same class, you should be able to write half of it in say VB.net and then write the rest in C# by inheriting the VB.net class.
If someone still needs it (like I do).

You should also consider changing some of your rules to:
With the above improvements, and for more flexibility and readability, I would modify the regex to.
^(?=(.*[a-z]){3,})(?=(.*[A-Z]){2,})(?=(.*[0-9]){2,})(?=(.*[!@#$%^&*()\-__+.]){1,}).{8,}$
Basic Explanation
(?=(.*RULE){MIN_OCCURANCES,})
Each rule block is shown by (?=(){}). The rule and number of occurrences can then be easily specified and tested separately, before getting combined
Detailed Explanation
^ start anchor
(?=(.*[a-z]){3,}) lowercase letters. {3,} indicates that you want 3 of this group
(?=(.*[A-Z]){2,}) uppercase letters. {2,} indicates that you want 2 of this group
(?=(.*[0-9]){2,}) numbers. {2,} indicates that you want 2 of this group
(?=(.*[!@#$%^&*()\-__+.]){1,}) all the special characters in the [] fields. The ones used by regex are escaped by using the \ or the character itself. {1,} is redundant, but good practice, in case you change that to more than 1 in the future. Also keeps all the groups consistent
{8,} indicates that you want 8 or more
$ end anchor
And lastly, for testing purposes here is a robulink with the above regex
Dart lang:
import 'dart:math' show cos, sqrt, asin;
double calculateDistance(LatLng l1, LatLng l2) {
const p = 0.017453292519943295;
final a = 0.5 -
cos((l2.latitude - l1.latitude) * p) / 2 +
cos(l1.latitude * p) *
cos(l2.latitude * p) *
(1 - cos((l2.longitude - l1.longitude) * p)) /
2;
return 12742 * asin(sqrt(a));
}
As hanry has mentioned above putting liner iterpolator is fine. But if rotation is inside a set you must put android:shareInterpolator="false" to make it smooth.
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
**android:shareInterpolator="false"**
>
<rotate
android:interpolator="@android:anim/linear_interpolator"
android:duration="300"
android:fillAfter="true"
android:repeatCount="10"
android:repeatMode="restart"
android:fromDegrees="0"
android:toDegrees="360"
android:pivotX="50%"
android:pivotY="50%" />
<scale xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/linear_interpolator"
android:duration="3000"
android:fillAfter="true"
android:pivotX="50%"
android:pivotY="50%"
android:fromXScale="1.0"
android:fromYScale="1.0"
android:toXScale="0"
android:toYScale="0" />
</set>
If Sharedinterpolator being not false, the above code gives glitches.

From the point of view of porting a C program, a good way to understand this is to take an example:
#include <sys/stat.h>
#include <stdlib.h>
int main(void)
{
struct stat stbuf;
stat("c:foo.txt", &stbuf);
system("command");
printf("Hello, World\n");
return 0;
}
If we change stat
to _stat
, we can compile this program with Microsoft Visual C. We can also compile this program with MinGW, and with Cygwin.
Under Microsoft Visual C, the program will be linked to a MSVC redistributable run-time library: mxvcrtnn.dll
, where nn
is some version suffix. To ship this program we will have to include that DLL. That DLL provides _stat
, system
and printf
. (We also have the option of statically linking the run-time.)
Under MinGW, the program will be linked to msvcrt.dll
, which is an internal, undocumented, unversioned library that is part of Windows, and off-limits to application use. That library is essentially a fork of the redistributable run-time library from MS Visual C for use by Windows itself.
Under both of these, the program will have similar behaviors:
stat
function will return very limited information—no useful permissions or inode number, for instance.c:file.txt
is resolved according to the current working directory associated with drive c:
. system
uses cmd.exe /c
for running the external command.We can also compile the program under Cygwin. Similarly to the redistributable run-time used by MS Visual C, the Cygwin program will be linked to Cygwin's run-time libraries: cygwin1.dll
(Cygwin proper) and cyggcc_s-1.dll
(GCC run-time support). Since Cygwin is now under the LGPL, we can package with our program, even if it isn't GPL-compatible free software, and ship the program.
Under Cygwin, the library functions will behave differently:
stat
function has rich functionality, returning meaningful values in most of the fields.c:file.txt
is not understood at all as containing a drive letter reference, since c:
isn't followed by a slash. The colon is considered part of the name and somehow mangled into it. There is no concept of a relative path against a volume or drive in Cygwin, no "currently logged drive" concept, and no per-drive current working directory.system
function tries to use the /bin/sh -c
interpreter. Cygwin will resolve the /
path according to the location of your executable, and expect a sh.exe
program to be co-located with your executable.Both Cygwin and MinGW allow you to use Win32 functions. If you want to call MessageBox
or CreateProcess
, you can do that. You can also easily build a program which doesn't require a console window, using gcc -mwindows
, under MinGW and Cygwin.
Cygwin is not strictly POSIX. In addition to providing access to the Windows API, it also provides its own implementations of some Microsoft C functions (stuff found in msvcrt.dll
or the re-distributable msvcrtnn.dll
run-times). An example of this are the spawn*
family of functions like spawnvp
. These are a good idea to use instead of fork
and exec
on Cygwin since they map better to the Windows process creation model which has no concept of fork
.
Thus:
Cygwin programs are no less "native" than MS Visual C programs on grounds of requiring the accompaniment of libraries. Programming language implementations on Windows are expected to provide their own run-time, even C language implementations. There is no "libc" on Windows for public use.
The fact that MinGW requires no third-party DLL is actually a disadvantage; it is depending on an undocumented, Windows-internal fork of the Visual C run-time. MinGW does this because the GPL system library exception applies to msvcrt.dll
, which means that GPL-ed programs can be compiled and redistributed with MinGW.
Due to its much broader and deeper support for POSIX compared to msvcrt.dll
, Cygwin is by far the superior environment for porting POSIX programs. Since it is now under the LGPL, it allows applications with all sorts of licenses, open or closed source, to be redistributed. Cygwin even contains VT100 emulation and termios
, which work with the Microsoft console! A POSIX application that sets up raw mode with tcsetattr
and uses VT100 codes to control the cursor will work right in the cmd.exe
window. As far as the end-user is concerned, it's a native console app making Win32 calls to control the console.
However:
/bin/sh
and other issues. These differences are what render Cygwin programs "non-native". If a program takes a path as an argument, or input from a dialog box, Windows users expect that path to work the same way as it does in other Windows programs. If it doesn't work that way, that's a problem.Plug: Shortly after the LGPL announcement, I started the Cygnal (Cygwin Native Application Library) project to provide a fork of the Cygwin DLL which aims to fix these issues. Programs can be developed under Cygwin, and then deployed with the Cygnal version of cygwin1.dll
without recompiling. As this library improves, it will gradually eliminate the need for MinGW.
When Cygnal solves the path handling problem, it will be possible to develop a single executable which works with Windows paths when shipped as a Windows application with Cygnal, and seamlessly works with Cygwin paths when installed in your /usr/bin
under Cygwin. Under Cygwin, the executable will transparently work with a path like /cygdrive/c/Users/bob
. In the native deployment where it is linking against the Cygnal version of cygwin1.dll
, that path will make no sense, whereas it will understand c:foo.txt
.
.prop('disabled')
will return a Boolean:
var isDisabled = $('textbox').prop('disabled');

Here is some sample code of how to add a button named Add. You should declare the variable as a member variable, and the naming convention for member variables is to start with the letter "m".
Hit Alt+Enter on the classes to add the missing references.
Add this to your activity_main.xml:
<Button
android:id="@+id/buttonAdd"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="ADD"
/>
Add this to your MainActivity.java:
public class MainActivity extends AppCompatActivity {
Button mButtonAdd;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mButtonAdd = findViewById(R.id.buttonAdd);
mButtonAdd.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// do something here
}
});

Assuming that we're talking about overloading operator <<
for all classes derived from std::ostream
to handle the Matrix
class (and not overloading <<
for Matrix
class), it makes more sense to declare the overload function outside the Math namespace in the header.
Use a friend function only if the functionality cannot be achieved via the public interfaces.
Matrix.h
namespace Math {
class Matrix {
//...
};
}
std::ostream& operator<<(std::ostream&, const Math::Matrix&);
Note that the operator overload is declared outside the namespace.
Matrix.cpp
using namespace Math;
using namespace std;
ostream& operator<< (ostream& os, const Matrix& obj) {
os << obj.getXYZ() << obj.getABC() << '\n';
return os;
}
On the other hand, if your overload function does need to be made a friend i.e. needs access to private and protected members.
Math.h
namespace Math {
class Matrix {
public:
friend std::ostream& operator<<(std::ostream&, const Matrix&);
};
}
You need to enclose the function definition with a namespace block instead of just using namespace Math;
.
Matrix.cpp
using namespace Math;
using namespace std;
namespace Math {
ostream& operator<<(ostream& os, const Matrix& obj) {
os << obj.XYZ << obj.ABC << '\n';
return os;
}
}
Here is another image map plugin I wrote to enhance image maps: https://github.com/gestixi/pictarea
It makes it easy to highlight all the area and let you specify different styles depending on the state of the zone: normal, hover, active, disable.
You can also specify how many zones can be selected at the same time.
To the great answers that already included here I want to add something that missing in my perspective - an illustration.
As you already JVM divides the allocated memory to a Java program into two parts. one is stack and another one is heap. Stack is used for execution purpose and heap is used for storage purpose. In that heap memory, JVM allocates some memory specially meant for string literals. This part of the heap memory is called string constants pool.
So for example, if you init the following objects:
String s1 = "abc";
String s2 = "123";
String obj1 = new String("abc");
String obj2 = new String("def");
String obj3 = new String("456);
String literals s1
and s2
will go to string constant pool, objects obj1, obj2, obj3 to the heap. All of them, will be referenced from the Stack.
Also, please note that "abc" will appear in heap and in string constant pool. Why is String s1 = "abc"
and String obj1 = new String("abc")
will be created this way? It's because String obj1 = new String("abc")
explicitly creates a new and referentially distinct instance of a String object and String s1 = "abc"
may reuse an instance from the string constant pool if one is available. For a more elaborate explanation: https://stackoverflow.com/a/3298542/2811258
If you Navbar code as like as follow:
<div class="navbar navbar-default navbar-fixed-top">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Project name</a>
</div>
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav">
<li class="active"><a href="#">Home</a></li>
<li><a href="#about">About</a></li>
<li><a href="#contact">Contact</a></li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li class="dropdown-header">Nav header</li>
<li><a href="#">Separated link</a></li>
<li><a href="#">One more separated link</a></li>
</ul>
</li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li><a href="../navbar/">Default</a></li>
<li><a href="../navbar-static-top/">Static top</a></li>
<li class="active"><a href="./">Fixed top</a></li>
</ul>
</div><!--/.nav-collapse -->
</div>
Then just use the following CSS style to change hover color of your navbar-brand
.navbar-default .navbar-brand:hover,
.navbar-default .navbar-brand:focus {
color: white;
}
So your navbad-brand
hover color will be changed to white. I just tested it and it's working for me correctly.
The datetime.now()

Another way is to get Base64 encoded token of "username:password" from any online website like - https://www.base64encode.org/ and pass it as Authorization
header of curl
as follows:
curl -i -H 'Authorization:Basic dXNlcm5hbWU6cGFzc3dvcmQ=' http://localhost:8080/
Here, dXNlcm5hbWU6cGFzc3dvcmQ=
is Base64
encoded token of username:password
.
This implements a checkbox as a button which shows either Yes or No depending on its 'checked' state. So it demonstrates one way of replacing text using CSS without having to write any code.
It will still behave like a checkbox as far as returning (or not returning) a POST value, but from a display point of view it looks like a toggle button.
The colours may not be to your liking, they're only there to illustrate a point.
The HTML is:
<input type="checkbox" class="yesno" id="testcb" /><label for="testcb"><span></span></label>
...and the CSS is:
/* --------------------------------- */
/* Make the checkbox non-displayable */
/* --------------------------------- */
input[type="checkbox"].yesno {
display:none;
}
/* --------------------------------- */
/* Set the associated label <span> */
/* the way you want it to look. */
/* --------------------------------- */
input[type="checkbox"].yesno+label span {
display:inline-block;
width:80px;
height:30px;
text-align:center;
vertical-align:middle;
color:#800000;
background-color:white;
border-style:solid;
border-width:1px;
border-color:black;
cursor:pointer;
}
/* --------------------------------- */
/* By default the content after the */
/* the label <span> is "No" */
/* --------------------------------- */
input[type="checkbox"].yesno+label span:after {
content:"No";
}
/* --------------------------------- */
/* When the box is checked the */
/* content after the label <span> */
/* is "Yes" (which replaces any */
/* existing content). */
/* When the box becomes unchecked the*/
/* content reverts to the way it was.*/
/* --------------------------------- */
input[type="checkbox"].yesno:checked+label span:after {
content:"Yes";
}
/* --------------------------------- */
/* When the box is checked the */
/* label <span> looks like this */
/* (which replaces any existing) */
/* When the box becomes unchecked the*/
/* layout reverts to the way it was. */
/* --------------------------------- */
input[type="checkbox"].yesno:checked+label span {
color:green;
background-color:#C8C8C8;
}
I've only tried it on Firefox, but it's standard CSS so it ought to work elsewhere.
There are three methods of passing an object to a function as a parameter:
Go through the following example:
class Sample
{
public:
int *ptr;
int mVar;
Sample(int i)
{
mVar = 4;
ptr = new int(i);
}
~Sample()
{
delete ptr;
}
void PrintVal()
{
cout << "The value of the pointer is " << *ptr << endl
<< "The value of the variable is " << mVar;
}
};
void SomeFunc(Sample x)
{
cout << "Say i am in someFunc " << endl;
}
int main()
{
Sample s1= 10;
SomeFunc(s1);
s1.PrintVal();
char ch;
cin >> ch;
}
Output:
Say i am in someFunc
The value of the pointer is -17891602
The value of the variable is 4
For XAMPP on MACOS or Linux, remove the semicolon in php.ini file after extension=curl.so
An array in PHP is a map of keys to values:
$array = array();
$array["yellow"] = 3;
$array["green"] = 4;
If you want to do something with each key-value-pair in your array, you can use the foreach
control structure:
foreach ($array as $key => $value)
The $array variable is the array you will be using. The $key and $value variables will contain a key-value-pair in every iteration of the foreach
loop. In this example, they will first contain "yellow" and 3, then "green" and 4.
You can use an alternative notation if you don't care about the keys:
foreach ($array as $value)
Better Way -
double value = 10.567;
int result = (int)((value - (int)value) * 100);
Console.WriteLine(result);
Output -
56

You can see your available images using:
docker images
Then you can run in detached mode so your terminal is still usable. You have several options to run it using a repository name (with or without a tag) or image ID:
docker run -d repository
docker run -d repository:tag
docker run -d image_id
Then you can check your container is running using
docker ps
docker ps
gives you a container ID. You can use it or just the 2/3 first characters to go into your container using:
docker exec -it container_id /bin/bash
And you can stop it using docker stop container_id
and docker rm container_id
.
You can also run your container with -rm
arguments so if you stop your container it will automatically be removed.
The main difference between fork()
and exec()
is that,
The fork()
system call creates a clone of the currently running program. The original program continues execution with the next line of code after the fork() function call. The clone also starts execution at the next line of code.
Look at the following code that i got from http://timmurphy.org/2014/04/26/using-fork-in-cc-a-minimum-working-example/
#include <stdio.h>
#include <unistd.h>
int main(int argc, char **argv)
{
printf("--beginning of program\n");
int counter = 0;
pid_t pid = fork();
if (pid == 0)
{
// child process
int i = 0;
for (; i < 5; ++i)
{
printf("child process: counter=%d\n", ++counter);
}
}
else if (pid > 0)
{
// parent process
int j = 0;
for (; j < 5; ++j)
{
printf("parent process: counter=%d\n", ++counter);
}
}
else
{
// fork failed
printf("fork() failed!\n");
return 1;
}
printf("--end of program--\n");
return 0;
}
This program declares a counter variable, set to zero, before fork()
ing. After the fork call, we have two processes running in parallel, both incrementing their own version of counter. Each process will run to completion and exit. Because the processes run in parallel, we have no way of knowing which will finish first. Running this program will print something similar to what is shown below, though results may vary from one run to the next.
--beginning of program
parent process: counter=1
parent process: counter=2
parent process: counter=3
child process: counter=1
parent process: counter=4
child process: counter=2
parent process: counter=5
child process: counter=3
--end of program--
child process: counter=4
child process: counter=5
--end of program--
The exec()
family of system calls replaces the currently executing code of a process with another piece of code. The process retains its PID but it becomes a new program. For example, consider the following code:
#include <stdio.h>
#include <unistd.h>
main() {
char program[80],*args[3];
int i;
printf("Ready to exec()...\n");
strcpy(program,"date");
args[0]="date";
args[1]="-u";
args[2]=NULL;
i=execvp(program,args);
printf("i=%d ... did it work?\n",i);
}
This program calls the execvp()
function to replace its code with the date program. If the code is stored in a file named exec1.c, then executing it produces the following output:
Ready to exec()...
Tue Jul 15 20:17:53 UTC 2008
The program outputs the line -Ready to exec() . . . ? and after calling the execvp() function, replaces its code with the date program. Note that the line - . . . did it work? is not displayed, because at that point the code has been replaced. Instead, we see the output of executing -date -u.?

I meet this problem when I try to use mingw to compile the xgboost lib in Win10. Finally I found the solution.
Create a file named as .bashrc in your home directory (usually the C:\Users\username). Then add the path to it. Remember to use quotes if your path contains blank, and remember to use /c/ instead of C:/
For example:
PATH=$PATH:"/c/Program Files/mingw-w64/x86_64-7.2.0-posix-seh-rt_v5-rev1/mingw64/bin"
I had this exact frustrating message. What finally worked for me was deleting all files and folders inside /packages and letting VS re-fetch everything the next build.
Just use the *args
parameter, which allows you to pass as many arguments as you want after your a,b,c
. You would have to add some logic to map args
->c,d,e,f
but its a "way" of overloading.
def myfunc(a,b, *args, **kwargs):
for ar in args:
print ar
myfunc(a,b,c,d,e,f)
And it will print values of c,d,e,f
Similarly you could use the kwargs
argument and then you could name your parameters.
def myfunc(a,b, *args, **kwargs):
c = kwargs.get('c', None)
d = kwargs.get('d', None)
#etc
myfunc(a,b, c='nick', d='dog', ...)
And then kwargs
would have a dictionary of all the parameters that are key valued after a,b
You can achieve this by setting the android:noHistory

May I suggest
getattr(re.search(r"<title>(.*)</title>", s, re.IGNORECASE), 'groups', lambda:[u""])()[0]
This returns an empty string by default if the pattern has not been found, or the first match.
Another option could be:
var initial = function() {
console.log( 'initial function!' );
}
var iWantToExecuteThisOneToo = function () {
console.log( 'the other function that i wanted to execute!' );
}
function extendFunction( oldOne, newOne ) {
return (function() {
oldOne();
newOne();
})();
}
var extendedFunction = extendFunction( initial, iWantToExecuteThisOneToo );

Since it hasn't been mentioned so far, as of Java 10 you can use the new copyOf
factory method:
List.copyOf(set);
From the Javadoc:
Returns an unmodifiable List containing the elements of the given Collection, in its iteration order.
Note that this creates a new list (ImmutableCollections$ListN
to be precise) under the hood by
Collection#toArray()
on the given set and theni donot think onSaveInstanceState
is a good solution. it just use for activity which had been destoryed.
From android 3.0 the Fragmen has been manager by FragmentManager, the condition is: one activity mapping manny fragments, when the fragment is added(not replace: it will recreated) in backStack, the view will be destored. when back to the last one, it will display as before.
So i think the fragmentManger and transaction is good enough to handle it.
Indentation in Python is important and this is just not for code readability, unlike many other programming languages. If there is any white space or tab in your code between consecutive commands, python will give this error as Python is sensitive to this. We are likely to get this error when we do copy and paste of code to any Python. Make sure to identify and remove these spaces using a text editor like Notepad++ or manually remove the whitespace from the line of code where you are getting an error.
Step1 :Gives error
L = [[1, 2, 3], [4, 5, 6], [7, 8, 9, 10]]
print(L[2: ])
Step2: L = [[1, 2, 3], [4, 5, 6], [7, 8, 9, 10]]print(L[2: ])
Step3: No error after space was removed
L = [[1, 2, 3], [4, 5, 6], [7, 8, 9, 10]]
print(L[2: ])
OUTPUT: [[7, 8, 9, 10]]

The one answer is fine but requires a little reading into. Especially with the new terminology "stop".
My Go -- organized by differences to make it useful in addition to the first answer by Daniel above:
1) negative indexes. Substring requires positive indexes and will set a negative index to 0. Slice's negative index means the position from the end of the string.
"1234".substring(-2, -1) == "1234".substring(0,0) == ""
"1234".slice(-2, -1) == "1234".slice(2, 3) == "3"
2) Swapping of indexes. Substring will reorder the indexes to make the first index less than or equal to the second index.
"1234".substring(3,2) == "1234".substring(2,3) == "3"
"1234".slice(3,2) == ""
General comment -- I find it weird that the second index is the position after the last character of the slice or substring. I would expect "1234".slice(2,2) to return "3". This makes Andy's confusion above justified -- I would expect "1234".slice(2, -1) to return "34". Yes, this means I'm new to Javascript. This means also this behavior:
"1234".slice(-2, -2) == "", "1234".slice(-2, -1) == "3", "1234".slice(-2, -0) == "" <-- you have to use length or omit the argument to get the 4.
"1234".slice(3, -2) == "", "1234".slice(3, -1) == "", "1234".slice(3, -0) == "" <-- same issue, but seems weirder.
My 2c.
I met the same problem before, also read the answers here, but doesn't found any satisfy solution can balance the compatibility, performance and well format output, the Jython can't work with extend C packages and slower than CPython. So finally I decided to invent the wheel myself, it took my 5 nights, I hope it can help you too: jpserve(https://github.com/johnhuang-cn/jpserve).
JPserve provides a simple way to call Python and exchange the result by well format JSON, few performance loss. The following is the sample code.
At first, start jpserve on Python side
>>> from jpserve.jpserve import JPServe
>>> serve = JPServe(("localhost", 8888))
>>> serve.start()
INFO:JPServe:JPServe starting...
INFO:JPServe:JPServe listening in localhost 8888
Then call Python from JAVA side:
PyServeContext.init("localhost", 8888);
PyExecutor executor = PyServeContext.getExecutor();
script = "a = 2\n"
+ "b = 3\n"
+ "_result_ = a * b";
PyResult rs = executor.exec(script);
System.out.println("Result: " + rs.getResult());
---
Result: 6
A simple example that will clear both during executing script or inside script while calling a function.
#!/bin/bash
echo "parameterized function example"
function print_param_value(){
value1="${1}" # $1 represent first argument
value2="${2}" # $2 represent second argument
echo "param 1 is ${value1}" # As string
echo "param 2 is ${value2}"
sum=$(($value1+$value2)) # Process them as number
echo "The sum of two value is ${sum}"
}
print_param_value "6" "4" # Space-separated value
# You can also pass parameters during executing the script
print_param_value "$1" "$2" # Parameter $1 and $2 during execution
# Suppose our script name is "param_example".
# Call it like this:
#
# ./param_example 5 5
#
# Now the parameters will be $1=5 and $2=5
For people getting the windows store window when writing python in the console, all you have to do is go to configuration -> Manage app execution aliases
and disable the toggles that say python.
then, add the following folders to the PATH.
C:\Users\alber\AppData\Local\Programs\Python\Python39\
C:\Users\alber\AppData\Local\Programs\Python\Python39\Scripts\
Create this way.
Create procedure dept_count(dept_name varchar(20),d_count integer)
begin
select count(*) into d_count
from instructor
where instructor.dept_name=dept_count.dept_name
end
Here's a little cmd script you can copy-n-paste into a file named something like where.cmd
:
@echo off
rem - search for the given file in the directories specified by the path, and display the first match
rem
rem The main ideas for this script were taken from Raymond Chen's blog:
rem
rem http://blogs.msdn.com/b/oldnewthing/archive/2005/01/20/357225.asp
rem
rem
rem - it'll be nice to at some point extend this so it won't stop on the first match. That'll
rem help diagnose situations with a conflict of some sort.
rem
setlocal
rem - search the current directory as well as those in the path
set PATHLIST=.;%PATH%
set EXTLIST=%PATHEXT%
if not "%EXTLIST%" == "" goto :extlist_ok
set EXTLIST=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH
:extlist_ok
rem - first look for the file as given (not adding extensions)
for %%i in (%1) do if NOT "%%~$PATHLIST:i"=="" echo %%~$PATHLIST:i
rem - now look for the file adding extensions from the EXTLIST
for %%e in (%EXTLIST%) do @for %%i in (%1%%e) do if NOT "%%~$PATHLIST:i"=="" echo %%~$PATHLIST:i
CSL's answer was implemented in a project I'm working on but the problem I incurred was scaling out on Azure broke our file downloads. Instead, I was able to do this with one AJAX call:
SERVER
[HttpPost]
public FileResult DownloadInvoice(int id1, int id2)
{
//necessary to get the filename in the success of the ajax callback
HttpContext.Response.Headers.Add("Access-Control-Expose-Headers", "Content-Disposition");
byte[] fileBytes = _service.GetInvoice(id1, id2);
string fileName = "Invoice.xlsx";
return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, fileName);
}
CLIENT (modified version of Handle file download from ajax post)
$("#downloadInvoice").on("click", function() {
$("#loaderInvoice").removeClass("d-none");
var xhr = new XMLHttpRequest();
var params = [];
xhr.open('POST', "@Html.Raw(Url.Action("DownloadInvoice", "Controller", new { id1 = Model.Id1, id2 = Model.Id2 }))", true);
xhr.responseType = 'arraybuffer';
xhr.onload = function () {
if (this.status === 200) {
var filename = "";
var disposition = xhr.getResponseHeader('Content-Disposition');
if (disposition && disposition.indexOf('attachment') !== -1) {
var filenameRegex = /filename[^;=\n]*=((['"]).*?\2|[^;\n]*)/;
var matches = filenameRegex.exec(disposition);
if (matches != null && matches[1]) filename = matches[1].replace(/['"]/g, '');
}
var type = xhr.getResponseHeader('Content-Type');
var blob = typeof File === 'function'
? new File([this.response], filename, { type: type })
: new Blob([this.response], { type: type });
if (typeof window.navigator.msSaveBlob !== 'undefined') {
// IE workaround for "HTML7007: One or more blob URLs were revoked by closing the blob for which they were created. These URLs will no longer resolve as the data backing the URL has been freed."
window.navigator.msSaveBlob(blob, filename);
} else {
var URL = window.URL || window.webkitURL;
var downloadUrl = URL.createObjectURL(blob);
if (filename) {
// use HTML5 a[download] attribute to specify filename
var a = document.createElement("a");
// safari doesn't support this yet
if (typeof a.download === 'undefined') {
window.location = downloadUrl;
} else {
a.href = downloadUrl;
a.download = filename;
document.body.appendChild(a);
a.click();
}
} else {
window.location = downloadUrl;
}
setTimeout(function() {
URL.revokeObjectURL(downloadUrl);
$("#loaderInvoice").addClass("d-none");
}, 100); // cleanup
}
}
};
xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
xhr.send($.param(params));
});
Check out SQL For Smarties. I thought I was pretty good with SQL too, until I read that book... Goes into tons of depth, talks about things I've not seen elsewhere (I.E. difference between 3'rd and 4'th normal form, Boyce Codd Normal Form, etc)...
I was getting the same error with a service access. It was working in browser, but wasnt working when I try to access it in my asp.net/c# application. I changed application pool from appPoolIdentity to NetworkService, and it start working. Seems like a permission issue to me.
A convenient way would be boost's string algorithms library.
#include <boost/algorithm/string/classification.hpp> // Include boost::for is_any_of
#include <boost/algorithm/string/split.hpp> // Include for boost::split
// ...
std::vector<std::string> words;
std::string s;
boost::split(words, s, boost::is_any_of(", "), boost::token_compress_on);
I solve that problem setting JAVA_HOME, CLASSPATH.
People sometimes skip JAVA_HOME and CLASSPATH when setting Java_path.
So try to check Environment Variable.
CLASSPATH -> .;
JAVA_HOME -> C:\Program Files\Java\jdk(version) or where Java installed
and then check the xml file which can have error(Do not naming well-known things such as button,text etc)
There are many ways to solve the same. One of the easiest ways to solve using Java 8 is given below :
As per your requirement, To sort in alphabetical order based on the map's key name
1st way :
list = list.stream()
.sorted((a,b)-> (a.get("name")).compareTo(b.get("name")))
.collect(Collectors.toList());
Or,
list = list.stream()
.sorted(Comparator.comparing(map->map.get("name")))
.collect(Collectors.toList());
2nd way :
Collections.sort(list, Comparator.comparing(map -> map.get("name")));
3rd way :
list.sort(Comparator.comparing(map-> map.get("name")));
Try this:
<uses-permission android:name="android.permission.INTERNET"/>
And your activity names
must be like this with capital letters
:
<activity android:name=".Addfriend"/>
<activity android:name=".UpdateDetails"/>
<activity android:name=".Details"/>
<activity android:name=".Updateimage"/>
Map
s.No, its not possible with objects.
You should either iterate with for..in
, or Object.keys
, like this
for (var key in dictionary) {
// check if the property/key is defined in the object itself, not in parent
if (dictionary.hasOwnProperty(key)) {
console.log(key, dictionary[key]);
}
}
Note: The if
condition above is necessary, only if you want to iterate the properties which are dictionary
object's very own. Because for..in
will iterate through all the inherited enumerable properties.
Or
Object.keys(dictionary).forEach(function(key) {
console.log(key, dictionary[key]);
});
In ECMAScript 2015, you can use Map
objects and iterate them with Map.prototype.entries
. Quoting example from that page,
var myMap = new Map();
myMap.set("0", "foo");
myMap.set(1, "bar");
myMap.set({}, "baz");
var mapIter = myMap.entries();
console.log(mapIter.next().value); // ["0", "foo"]
console.log(mapIter.next().value); // [1, "bar"]
console.log(mapIter.next().value); // [Object, "baz"]
Or iterate with for..of
, like this
'use strict';
var myMap = new Map();
myMap.set("0", "foo");
myMap.set(1, "bar");
myMap.set({}, "baz");
for (const entry of myMap.entries()) {
console.log(entry);
}
[ '0', 'foo' ]
[ 1, 'bar' ]
[ {}, 'baz' ]
Or
for (const [key, value] of myMap.entries()) {
console.log(key, value);
}
0 foo
1 bar
{} baz
ECMAScript 2017 would introduce a new function Object.entries
. You can use this to iterate the object as you wanted.
'use strict';
const object = {'a': 1, 'b': 2, 'c' : 3};
for (const [key, value] of Object.entries(object)) {
console.log(key, value);
}
a 1
b 2
c 3
You have to check every ID in tableA against every ID in tableB. A fully featured RDBMS (such as Oracle) would be able to optimize that into an INDEX FULL FAST SCAN and not touch the table at all. I don't know whether H2's optimizer is as smart as that.
H2 does support the MINUS syntax so you should try this
select id from tableA
minus
select id from tableB
order by id desc
That may perform faster; it is certainly worth benchmarking.
The only thing the eclipse plugin is checking is the tomcat version inside:
catalina.jar!/org/apache/catalina/util/ServerInfo.properties
I replaced the properties file with the one in tomcat7 and that fixed the issue for eclipse
In order to be able to deploy the spring-websockets sample app you need to edit the following file in eclipse:
.settings/org.eclipse.wst.common.project.facet.core.xml
And change the web version to 2.5
<installed facet="jst.web" version="2.5"/>
One of the main benefits of using streams is that it gives the ability to process data in a declarative way, that is, using a functional style of programming. It also gives multi-threading capability for free meaning there is no need to write any extra multi-threaded code to make your stream concurrent.
Assuming the reason you are exploring this style of programming is that you want to exploit these benefits then your first code sample is potentially not functional since the foreach
method is classed as being terminal (meaning that it can produce side-effects).
The second way is preferred from functional programming point of view since the map function can accept stateless lambda functions. More explicitly, the lambda passed to the map function should be
ArrayList
).Another benefit with the second approach is if the stream is parallel and the collector is concurrent and unordered then these characteristics can provide useful hints to the reduction operation to do the collecting concurrently.
I have users who have not been completing all required data.
<cfset unloadCheck=0>//a ColdFusion precheck in my page generation to see if unload check is needed
var erMsg="";
$(document).ready(function(){
<cfif q.myData eq "">
<cfset unloadCheck=1>
$("#myInput").change(function(){
verify(); //function elsewhere that checks all fields and populates erMsg with error messages for any fail(s)
if(erMsg=="") window.onbeforeunload = null; //all OK so let them pass
else window.onbeforeunload = confirmExit(); //borrowed from Jantimon above;
});
});
<cfif unloadCheck><!--- if any are outstanding, set the error message and the unload alert --->
verify();
window.onbeforeunload = confirmExit;
function confirmExit() {return "Data is incomplete for this Case:"+erMsg;}
</cfif>
You can execute:
$ mpicc -showme
result :
gcc -I/Users/<USER_NAME>/openmpi-2.0.1/include -L/Users/<USER_NAME>/openmpi-2.0.1/lib -lmp
This command shows you the necessary libraries to compile mpicc
Example:
$ mpicc -g -I/Users/<USER_NAME>/openmpi-2.0.1/include -o [nameExec] [objetcs.o...] [program.c] -lm
$ mpicc -g -I/Users/<USER_NAME>/openmpi-2.0.1/include -o example file_object.o my_program.c otherlib.o -lm
this command generates executable with your program in example, you can execute :
$ ./example
How about like this:
char* cmd = "./foo 1 2 3";
system(cmd);
Don't apply the orientation to the application element, instead you should apply the attribute to the activity element, and you must also set configChanges
as noted below.
Example:
<activity
android:screenOrientation="portrait"
android:configChanges="orientation|keyboardHidden">
</activity>
This is applied in the manifest file AndroidManifest.xml
.
Just copy & paste any JQuery file in your project and add a Global.asax
file and modify it as below:
I just paste the JQuery file in my project and add a reference in Global.asax file:

{
ScriptManager.ScriptResourceMapping.AddDefinition(
"jquery",
new ScriptResourceDefinition
{
Path = "~/jquery-1.10.2.js",
DebugPath = "~/jquery-1.10.2.js",
CdnPath = "http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.10.2.min.js",
CdnDebugPath = "http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.10.2.js",
CdnSupportsSecureConnection = true,

final JTextField textFieldA = new HintTextField("A hint here");
final JTextField textFieldB = new HintTextField("Another hint here");
frame.add(textFieldA, BorderLayout.NORTH);
frame.add(textFieldB, BorderLayout.CENTER);
JButton btnGetText = new JButton("Get text");
btnGetText.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
String message = String.format("textFieldA='%s', textFieldB='%s'",
textFieldA.getText(), textFieldB.getText());
JOptionPane.showMessageDialog(frame, message);
}
});
frame.add(btnGetText, BorderLayout.SOUTH);
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.setVisible(true);
frame.pack();
}
}
class HintTextField extends JTextField implements FocusListener {
private final String hint;
private boolean showingHint;
public HintTextField(final String hint) {
super(hint);
this.hint = hint;
this.showingHint = true;
super.addFocusListener(this);
}
@Override
public void focusGained(FocusEvent e) {
if(this.getText().isEmpty()) {
super.setText("");
showingHint = false;
}
}
@Override
public void focusLost(FocusEvent e) {
if(this.getText().isEmpty()) {
super.setText(hint);
showingHint = true;
}
}
@Override
public String getText() {
return showingHint ? "" : super.getText();
}
}
If you're still on Java 1.5, replace the this.getText().isEmpty()
with this.getText().length() == 0
.

Google Maps API v3:
I initialized Google Map and added markers to it. Later, I wanted to retrieve all markers and did it simply by accessing the map property "markers".
var map = new GMaps({
div: '#map',
lat: 40.730610,
lng: -73.935242,
});
var myMarkers = map.markers;
You can loop over it and access all Marker methods listed at Google Maps Reference.
It can be done, I found it elsewhere on the web...this is no way my work ! :)

In the second version, you're passing the String returned from this.id
. Not the element itself.
So id.value
won't give you what you want.
You would need to pass the element with this
.
doSomething(this)
then:
function(el){
var value = el.value;
...
}
Note: In some browsers, the second one would work if you did:
window[id].value
because element IDs are a global property, but this is not safe.
It makes the most sense to just pass the element with this
instead of fetching it again with its ID.
I was also getting same error while installing scikit-fuzzy. I resolved error as follows:
choose file according to python version like amd64 for python3 and other win32 file for the python27
pip install --user skfuzzy
I hope, It will work for you
Your fundamental problem is that grep
works one line at a time - so it cannot find a SELECT statement spread across lines.
Your second problem is that the regex you are using doesn't deal with the complexity of what can appear between SELECT and FROM - in particular, it omits commas, full stops (periods) and blanks, but also quotes and anything that can be inside a quoted string.
I would likely go with a Perl-based solution, having Perl read 'paragraphs' at a time and applying a regex to that. The downside is having to deal with the recursive search - there are modules to do that, of course, including the core module File::Find.
In outline, for a single file:
$/ = "\n\n"; # Paragraphs
while (<>)
{
if ($_ =~ m/SELECT.*customerName.*FROM/mi)
{
printf file name
go to next file
}
}
That needs to be wrapped into a sub that is then invoked by the methods of File::Find.
If You try to connect by pysftp to "normal" FTP You have to set hostkey to None.
import pysftp
cnopts = pysftp.CnOpts()
cnopts.hostkeys = None
with pysftp.Connection(host='****',username='****',password='***',port=22,cnopts=cnopts) as sftp:
print('DO SOMETHING')
I'd combine bash and mysql:
for i in $(mysql -Ne "select id from information_schema.processlist where user like 'foo%user' and time > 300;"); do
mysql -e "kill ${i}"
done
You can use the hashlib library for Python. The shake_128 and shake_256 algorithms provide variable length hashes. Here's some working code (Python3):
import hashlib
>>> my_string = 'hello shake'
>>> hashlib.shake_256(my_string.encode()).hexdigest(5)
'34177f6a0a'
Notice that with a length parameter x (5 in example) the function returns a hash value of length 2x.
res = request.GET['paymentid']
will raise a KeyError
if paymentid
is not in the GET data.
Your sample php code checks to see if paymentid
is in the POST data, and sets $payID
to '' otherwise:
$payID = isset($_POST['paymentid']) ? $_POST['paymentid'] : ''
The equivalent in python is to use the get()
method with a default argument:
payment_id = request.POST.get('payment_id', '')
while debugging, this is what I see in the
response.GET: <QueryDict: {}>
,request.POST: <QueryDict: {}>
It looks as if the problem is not accessing the POST data, but that there is no POST data. How are you are debugging? Are you using your browser, or is it the payment gateway accessing your page? It would be helpful if you shared your view.
Once you are managing to submit some post data to your page, it shouldn't be too tricky to convert the sample php to python.

If you need to use a custom calendar, you might need to add some checks and some parameters. Hopefully it will provide a good starting point.
The best answer to this could be
Don't use selct for this job use input instead
like this
echo $this->Form->input('field_name', array(
'type' => 'select',
'options' => $options_arr,
'label' => 'label here',
'value' => $id, // default value
'escape' => false, // prevent HTML being automatically escaped
'error' => false,
'class' => 'form-control' // custom class you want to enter
));
Hope it helps.
The character is a backslash \
From the bash manual:
The backslash character ‘\’ may be used to remove any special meaning for the next character read and for line continuation.
Let's use the latest fat arrow functions:
navigator.geolocation.getCurrentPosition((loc) => {
console.log('The location in lat lon format is: [', loc.coords.latitude, ',', loc.coords.longitude, ']');
})
There are 4 main factors into why you would want to use synchronized
or java.util.concurrent.Lock
.
Note: Synchronized locking is what I mean when I say intrinsic locking.
When Java 5 came out with ReentrantLocks, they proved to have quite a noticeble throughput difference then intrinsic locking. If youre looking for faster locking mechanism and are running 1.5 consider j.u.c.ReentrantLock. Java 6's intrinsic locking is now comparable.
j.u.c.Lock has different mechanisms for locking. Lock interruptable - attempt to lock until the locking thread is interrupted; timed lock - attempt to lock for a certain amount of time and give up if you do not succeed; tryLock - attempt to lock, if some other thread is holding the lock give up. This all is included aside from the simple lock. Intrinsic locking only offers simple locking
Here is what made the error disappear for me:

Are you using Maven? If so,
To add it: Right-click on the project, Maven → Disable Maven Nature Right-click on the project, Configure → Convert to Maven Project.
And then clean
Edit 1:
If that doesn't resolve the issue try right-clicking on your project and select properties. Select Java Build Path → Library tab. Look for a JVM. If it's not there, click to add Library and add the default JVM. If VM is there, click edit and select the default JVM. Hopefully, that works.
Edit 2:
You can also try going into the folder where you have all your projects and delete the .metadata
for eclipse (be aware that you'll have to re-import all the projects afterwards! Also all the environment settings you've set would also have to be redone). After it was deleted just import the project again, and hopefully, it works.
You'll need a PDF API for C#. iTextSharp is one possible API, though better ones might exist.
iTextSharp Example
You must install iTextSharp.dll as a reference. Download iTextsharp from SourceForge.net This is a complete working program using a console application.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using iTextSharp.text.pdf;
using iTextSharp.text.xml;
namespace GetPages_PDF
{
class Program
{
static void Main(string[] args)
{
// Right side of equation is location of YOUR pdf file
string ppath = "C:\\aworking\\Hawkins.pdf";
PdfReader pdfReader = new PdfReader(ppath);
int numberOfPages = pdfReader.NumberOfPages;
Console.WriteLine(numberOfPages);
Console.ReadLine();
}
}
}
How about writing a custom attribute:
public class LocalizedDisplayNameAttribute: DisplayNameAttribute
{
public LocalizedDisplayNameAttribute(string resourceId)
: base(GetMessageFromResource(resourceId))
{ }
private static string GetMessageFromResource(string resourceId)
{
// TODO: Return the string from the resource file
}
}
which could be used like this:
public class MyModel
{
[Required]
[LocalizedDisplayName("labelForName")]
public string Name { get; set; }
}
In some cases it is possible using @import "file.css", and most modern browsers should support this, older browsers such as NN4, will go slightly nuts.
Note: the import statement must precede all other declarations in the file, and test it on all your target browsers before using it in production.
Or no float conversion at all by just specifying floats in the list.
l = [-1.2, 0.0, 1]
x = min(l)
or
l = min([-1.2, 0.0, 1])
tar.exe -acf out.zip in.txt
out.zip is an output folder or filename and in.txt is an input folder or filename. To use this command you should be in the file existing folder.
You could use cast
(as int) after replacing NaN
with 0
,
data_df = df.withColumn("Plays", df.call_time.cast('float'))
git tag -d 12345
git push origin :refs/tags/12345
git push --delete origin tagName
git tag -d tagName
The key here is to visualise the call tree. Once done that, the complexity is:
nodes of the call tree * complexity of other code in the function
the latter term can be computed the same way we do for a normal iterative function.
Instead, the total nodes of a complete tree are computed as
C^L - 1
------- , when C>1
/ C - 1
/
# of nodes =
\
\
L , when C=1
Where C is number of children of each node and L is the number of levels of the tree (root included).
It is easy to visualise the tree. Start from the first call (root node) then draw a number of children same as the number of recursive calls in the function. It is also useful to write the parameter passed to the sub-call as "value of the node".
So, in the examples above:
n level 1 n-1 level 2 n-2 level 3 n-3 level 4 ... ~ n levels -> L = n
n n-5 n-10 n-15 ... ~ n/5 levels -> L = n/5
n n/5 n/5^2 n/5^3 ... ~ log5(n) levels -> L = log5(n)
n level 1 n-1 n-1 level 2 n-2 n-2 n-2 n-2 ... n-3 n-3 n-3 n-3 n-3 n-3 n-3 n-3 ... ... ~ n levels -> L = n
n n-5 n-10 n-15 ... ~ n/5 levels -> L = n/5
Simple function. Transform strings like 'Ábç Éfg' to 'abc_efg'
/**
* @param $str
* @return mixed
*/
function sanitizeString($str) {
$str = preg_replace('/[áàãâä]/ui', 'a', $str);
$str = preg_replace('/[éèêë]/ui', 'e', $str);
$str = preg_replace('/[íìîï]/ui', 'i', $str);
$str = preg_replace('/[óòõôö]/ui', 'o', $str);
$str = preg_replace('/[úùûü]/ui', 'u', $str);
$str = preg_replace('/[ç]/ui', 'c', $str);
$str = preg_replace('/[^a-z0-9]/i', '_', $str);
$str = preg_replace('/_+/', '_', $str);
return $str;
}
Since you have not defined what an empty file is. Some might consider a file with just blank lines also an empty file. So if you want to check if your file contains only blank lines (any whitespace character, '\r', '\n', '\t'), you can follow the example below:
Python3
import re
def whitespace_only(file):
content = open(file, 'r').read()
if re.search(r'^\s*$', content):
return True
Explain: the example above uses regular expression (regex) to match the content (content
) of the file.
Specifically: for regex of: ^\s*$
as a whole means if the file contains only blank lines and/or blank spaces.
- ^
asserts position at start of a line
- \s
matches any whitespace character (equal to [\r\n\t\f\v ])
- *
Quantifier — Matches between zero and unlimited times, as many times as possible, giving back as needed (greedy)
- $
asserts position at the end of a line
Download Microsoft Drivers for PHP for SQL Server. Extract the files and use one of:
File Thread Safe VC Bulid
php_sqlsrv_53_nts_vc6.dll No VC6
php_sqlsrv_53_nts_vc9.dll No VC9
php_sqlsrv_53_ts_vc6.dll Yes VC6
php_sqlsrv_53_ts_vc9.dll Yes VC9
You can see the Thread Safety status in phpinfo().
Add the correct file to your ext directory and the following line to your php.ini:
extension=php_sqlsrv_53_*_vc*.dll
Use the filename of the file you used.
As Gordon already posted this is the new Extension from Microsoft and uses the sqlsrv_* API instead of mssql_*
Update:
On Linux you do not have the requisite drivers and neither the SQLSERV Extension.
Look at Connect to MS SQL Server from PHP on Linux? for a discussion on this.
In short you need to install FreeTDS and YES you need to use mssql_* functions on linux. see update 2
To simplify things in the long run I would recommend creating a wrapper class with requisite functions which use the appropriate API (sqlsrv_* or mssql_*) based on which extension is loaded.
Update 2: You do not need to use mssql_* functions on linux. You can connect to an ms sql server using PDO + ODBC + FreeTDS. On windows, the best performing method to connect is via PDO + ODBC + SQL Native Client since the PDO + SQLSRV driver can be incredibly slow.
If I'm reading your question correctly, objects in general are agnostic about where they are contained. They don't know who their parents are. To find that information, you have to parse the parent data structure. The DOM has ways of doing this for us when you're talking about element objects in a document, but it looks like you're talking about vanilla objects.
In my case it was the postBuffer..
git config --global http.postBuffer 524288000

Combining two previous answers, for Rails 4.0.4 (and up, presumably), this suffices at the end of config/boot.rb
:
require 'rails/commands/server'
module Rails
class Server
def default_options
super.merge({Port: 10524})
end
end
end
Other way to get a bitmap of an image is doing this:
Bitmap imagenAndroid = BitmapFactory.decodeResource(getResources(),R.drawable.jellybean_statue);
imageView.setImageBitmap(imagenAndroid);
I had this same issue and solved it by setting up my ~/.ssh/config file to explicitly use the correct username (i.e. the one you use to login to the server, not your local machine). So, for example:
Host server.hostname User username
I found this blog post helpful: http://www.highlevelbits.com/2007/04/svn-over-ssh-prompts-for-wrong-username.html
According to MySQL documentation, you should be able to just enclose that datetime string in single quotes, ('YYYY-MM-DD HH:MM:SS') and it should work. Look here: Date and Time Literals
So, in your case, the command should be as follows:
UPDATE products SET former_date='2011-12-18 13:17:17' WHERE id=1
svn rm --keep-local folder_name
Note: In svn 1.5.4 svn rm deletes unversioned files even when --keep-local is specified. See http://svn.haxx.se/users/archive-2009-11/0058.shtml for more information.
A little update on this post: if you are using ktx within your Android project, there is a little helper method that makes updating LayoutParams a lot easier.
If you want to update e.g. only the width you can do that with the following line in Kotlin.
tv.updateLayoutParams { width = WRAP_CONTENT }
You should ask whoever maintains the repo at git@mycogit/cit_pplus.git
.
Your commits were rejected by the pre-receive
hook of that repo (that's a user-configurable script that is intended to analyze incoming commits and decide if they are good enough to be accepted into the repo).
It is also a good idea to ask that person to update the hook, so it would print the reasons for the rejection.
If the maintainer is you yourself, then it looks like you've got a problem with your setup on the server-side. Please share more information then.
it is now simply:
let serialQueue = DispatchQueue(label: "my serial queue")
the default is serial, to get concurrent, you use the optional attributes argument .concurrent
This is the function that you need: Then just pass the x in a rename(X) and it will rename all values that appear and if it isn't in there it won't error
rename <-function(x){
oldNames = c("a","b","c")
newNames = c("d","e","f")
existing <- match(oldNames,names(x))
names(x)[na.omit(existing)] <- newNames[which(!is.na(existing))]
return(x)
}
>>> pd.Timestamp('2014-01-23 00:00:00', tz=None).to_datetime()
datetime.datetime(2014, 1, 23, 0, 0)
>>> pd.Timestamp(datetime.date(2014, 3, 26))
Timestamp('2014-03-26 00:00:00')
try this
var updateQueryStringParam = function (key, value) {
var baseUrl = [location.protocol, '//', location.host, location.pathname].join(''),
urlQueryString = document.location.search,
newParam = key + '=' + value,
params = '?' + newParam;
// If the "search" string exists, then build params from it
if (urlQueryString) {
var updateRegex = new RegExp('([\?&])' + key + '[^&]*');
var removeRegex = new RegExp('([\?&])' + key + '=[^&;]+[&;]?');
if( typeof value == 'undefined' || value == null || value == '' ) { // Remove param if value is empty
params = urlQueryString.replace(removeRegex, "$1");
params = params.replace( /[&;]$/, "" );
} else if (urlQueryString.match(updateRegex) !== null) { // If param exists already, update it
params = urlQueryString.replace(updateRegex, "$1" + newParam);
} else { // Otherwise, add it to end of query string
params = urlQueryString + '&' + newParam;
}
}
// no parameter was set so we don't need the question mark
params = params == '?' ? '' : params;
window.history.replaceState({}, "", baseUrl + params);
};
josonify works..but if you intend to just pass an array without the 'results' key, you can use json library from python. The following conversion works for me..
import json
@app.route('/test/json')
def test_json():
list = [
{'a': 1, 'b': 2},
{'a': 5, 'b': 10}
]
return json.dumps(list))
In 2015 I would go with:
Of course you may want to keep JS for easy project setup and to avoid the transpilation process... there is no ultimate solution.
Or just wait for ECMA6, 7, ... :)
