If the advice to add the closing braces work, I suggest adding indentation to your code so every closing brace is on a spaced separately, i.e.:
public class LuisRp3 {
public static void main(String[] args) throws FileNotFoundException {
// stuff
}
}
This just helps with readability.
If, on the other hand, you just forgot to copy the closing braces in your code, or the above suggestion doesn't work: open up the configuration and see if you can manually set the main class. I'm afraid I haven't used NetBeans much, so I can't help you with where that option is. My best guess is under "Run Configuration", or something like that.
Edit: See peeskillet's answer if adding closing braces doesn't work.
I've seen this error caused by a circular reference in the object graph. Including a pointer to the parent object from a child will cause the serializer to loop, and ultimately exceed the maximum message size.
If there's always a single CRLF, then:
myString = myString.Substring(0, myString.Length - 2);
If it may or may not have it, then:
Regex re = new Regex("\r\n$");
re.Replace(myString, "");
Both of these (by design), will remove at most a single CRLF. Cache the regex for performance.
Here's an example: App.config
<applicationSettings>
<MyApp.My.MySettings>
<setting name="Printer" serializeAs="String">
<value>1234 </value>
</setting>
</MyApp.My.MySettings>
</applicationSettings>
Dim strPrinterName as string = My.settings.Printer
A simple ddply
option:
ddply(test,.(id),function(x) head(x,1))
If speed is an issue, a similar approach could be taken with data.table
:
testd <- data.table(test)
setkey(testd,id)
testd[,.SD[1],by = key(testd)]
or this might be considerably faster:
testd[testd[, .I[1], by = key(testd]$V1]
Oh, be careful now! All that glitters is NOT gold! All of the “stats” dm views and functions have a problem for this type of thing. They only work against what is in cache and the lifetime of what is in cache can be measure in minutes. If you were to use such a thing to determine which SPs are candidates for being dropped, you could be in for a world of hurt when you delete SPs that were used just minutes ago.
The following excerpts are from Books Online for the given dm views…
sys.dm_exec_procedure_stats Returns aggregate performance statistics for cached stored procedures. The view contains one row per stored procedure, and the lifetime of the row is as long as the stored procedure remains cached. When a stored procedure is removed from the cache, the corresponding row is eliminated from this view.
sys.dm_exec_query_stats The view contains one row per query statement within the cached plan, and the lifetime of the rows are tied to the plan itself. When a plan is removed from the cache, the corresponding rows are eliminated from this view.

You might want to look at Python's decimal
module, which can make using floating point numbers and doing arithmetic with them a lot more intuitive. Here's a trivial example of one way of using it to "clean up" your list values:
>>> from decimal import *
>>> mylist = [0.30000000000000004, 0.5, 0.20000000000000001]
>>> getcontext().prec = 2
>>> ["%.2f" % e for e in mylist]
['0.30', '0.50', '0.20']
>>> [Decimal("%.2f" % e) for e in mylist]
[Decimal('0.30'), Decimal('0.50'), Decimal('0.20')]
>>> data = [float(Decimal("%.2f" % e)) for e in mylist]
>>> data
[0.3, 0.5, 0.2]
You don't use the :
syntax - pull
always modifies the currently checked-out branch. Thus:
git pull origin my_remote_branch
while you have my_local_branch
checked out will do what you want.
Since you already have the tracking branch set, you don't even need to specify - you could just do...
git pull
while you have my_local_branch
checked out, and it will update from the tracked branch.
From documentation https://docs.python.org/3/library/venv.html:
The pyvenv script has been deprecated as of Python 3.6 in favor of using python3 -m venv to help prevent any potential confusion as to which Python interpreter a virtual environment will be based on.
In order to create a virtual environment for particular project, create a file /home/user/path/to/create_venv.sh
:
#!/usr/bin/env bash
# define path to your project's directory
PROJECT_DIR=/home/user/path/to/Project1
# a directory with virtual environment
# will be created in your Project1 directory
# it recommended to add this path into your .gitignore
VENV_DIR="${PROJECT_DIR}"/venv
# https://docs.python.org/3/library/venv.html
python3 -m venv "${VENV_DIR}"
# activates the newly created virtual environment
. "${VENV_DIR}"/bin/activate
# prints activated version of Python
python3 -V
pip3 install --upgrade pip
# Write here all Python libraries which you want to install over pip
# An example or requirements.txt see here:
# https://docs.python.org/3/tutorial/venv.html#managing-packages-with-pip
pip3 install -r "${PROJECT_DIR}"/requirements.txt
echo "Virtual environment ${VENV_DIR} has been created"
deactivate
Then run this script in the console:
$ bash /home/user/path/to/create_venv.sh
You can add attributes using attr
like so:
$('#someid').attr('name', 'value');
However, for DOM properties like checked
, disabled
and readonly
, the proper way to do this (as of JQuery 1.6) is to use prop
.
$('#someid').prop('disabled', true);
This is another way to specify the range of the bit-vector.
x +: N, The start position of the vector is given by x and you count up from x by N.
There is also
x -: N, in this case the start position is x and you count down from x by N.
N is a constant and x is an expression that can contain iterators.
It has a couple of benefits -
It makes the code more readable.
You can specify an iterator when referencing bit-slices without getting a "cannot have a non-constant value" error.
You may like lfqueue, https://github.com/Taymindis/lfqueue. It’s lock free concurrent queue. I’m currently using it to consuming the queue from multiple incoming calls and works like a charm.
The default
keyword parameter should be given to the Column object.
Example:
Column(u'timestamp', TIMESTAMP(timezone=True), primary_key=False, nullable=False, default=time_now),
The default value can be a callable, which here I defined like the following.
from pytz import timezone
from datetime import datetime
UTC = timezone('UTC')
def time_now():
return datetime.now(UTC)
You can this query:
pip install image
I had pillow installed, and still, I got the error that you mentioned. But after I executed the above command, the error vanished. And My program worked perfectly.

Eclipse forgets to copy the default apps (ROOT, examples, etc.) when it creates a Tomcat folder inside the Eclipse workspace. Go to C:\apache-tomcat-7.0.34\webapps, R-click on the ROOT folder and copy it. Then go to your Eclipse workspace, go to the .metadata folder, and search for "wtpwebapps". You should find something like your-eclipse-workspace.metadata.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps (or .../tmp1/wtpwebapps if you already had another server registered in Eclipse). Go to the wtpwebapps folder, R-click, and paste ROOT (say "yes" if asked if you want to merge/replace folders/files). Then reload http://localhost/ to see the Tomcat welcome page.
I have mixed feelings about the Cocotron project. I'm glad they are releasing source code and sharing but I don't feel that they are doing things the easiest way.
Examples.
Apple has released the source code to the objective-c runtime, which includes properties and garbage collection. The Cocotron project however has their own implementation of the objective-c runtime. Why bother to duplicate the effort? There is even a Visual Studio Project file that can be used to build an objc.dll file. Or if you're really lazy, you can just copy the DLL file from an installation of Safari on Windows.
They also did not bother to leverage CoreFoundation, which is also open sourced by Apple. I posted a question about this but did not receive an answer.
I think the current best solution is to take source code from multiple sources (Apple, CocoTron, GnuStep) and merge it together to what you need. You'll have to read a lot of source but it will be worth the end result.
Can't you just use C++ and not use all other C++ features except this one?
If still no just strict C then I would recommend variadic functions instead.
# Open the file
f = open('morseCode.txt', 'r')
# Read the morse code data into "letters" [(lowercased letter, morse code), ...]
letters = []
for Line in f:
if not Line.strip(): break
letter, code = Line.strip().split() # Assuming the format is <letter><whitespace><morse code><newline>
letters.append((letter.lower(), code))
f.close()
# Get the input from the user
# (Don't use input() - it calls eval(raw_input())!)
i = raw_input("Enter a string to be converted to morse code or press <enter> to quit ")
# Convert the codes to morse code
out = []
for c in i:
found = False
for letter, code in letters:
if letter == c.lower():
found = True
out.append(code)
break
if not found:
raise Exception('invalid character: %s' % c)
# Print the output
print ' '.join(out)
With very few exceptions, this rule is golden:
!
?
), not implicitly unwrapped optionals (IUO) (!
)In other words, rather use:
var nameOfDaughter: String?
Instead of:
var nameOfDaughter: String!
if let
or guard let
Either unwrap variable like this:
if let nameOfDaughter = nameOfDaughter {
print("My daughters name is: \(nameOfDaughter)")
}
Or like this:
guard let nameOfDaughter = nameOfDaughter else { return }
print("My daughters name is: \(nameOfDaughter)")

Arduino sketches are written in C++.
Here is a typical construct you'll encounter:
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
...
lcd.begin(16, 2);
lcd.print("Hello, World!");
That's C++, not C.
Hence do yourself a favor and learn C++. There are plenty of books and online resources available.
if you are using emulator to run your app for local server. mention the local ip

For sub-objects, ReadSubtree()
gives you an xml-reader limited to the sub-objects, but I really think that you are doing this the hard way. Unless you have very specific requirements for handling unusual / unpredicatable xml, use XmlSerializer
(perhaps coupled with sgen.exe
if you really want).
XmlReader
is... tricky. Contrast to:
using System;
using System.Collections.Generic;
using System.Xml.Serialization;
public class ApplicationPool {
private readonly List<Account> accounts = new List<Account>();
public List<Account> Accounts {get{return accounts;}}
}
public class Account {
public string NameOfKin {get;set;}
private readonly List<Statement> statements = new List<Statement>();
public List<Statement> StatementsAvailable {get{return statements;}}
}
public class Statement {}
static class Program {
static void Main() {
XmlSerializer ser = new XmlSerializer(typeof(ApplicationPool));
ser.Serialize(Console.Out, new ApplicationPool {
Accounts = { new Account { NameOfKin = "Fred",
StatementsAvailable = { new Statement {}, new Statement {}}}}
});
}
}
try this.
filename = Path.ChangeExtension(".blah")
in you Case:
myfile= c:/my documents/my images/cars/a.jpg;
string extension = Path.GetExtension(myffile);
filename = Path.ChangeExtension(myfile,".blah")
You should look this post too:

According to the Swift 2.2 Book published by apple:
“You indicate type methods by writing the static
keyword before the method’s func keyword. Classes may also use the class
keyword to allow subclasses to override the superclass’s implementation of that method.”
Application locks are one way to roll your own locking with custom granularity while avoiding "helpful" lock escalation. See sp_getapplock.
Here is code you can get url segment.
{{ Request::segment(1) }}
If you don't want the data to be escaped then use {!! !!} else use {{ }}.
{!! Request::segment(1) !!}
use this function to create and set attributes at the same time
function createNode(node, attributes){
const el = document.createElement(node);
for(let key in attributes){
el.setAttribute(key, attributes[key]);
}
return el;
}
use it like so
const input = createNode('input', {
name: 'test',
type: 'text',
placeholder: 'Test'
});
document.body.appendChild(input);
as long as you did not commit you can type
git merge --abort
just as the command line suggested.

Issue could be with different table(might not exists or grant privilege is not for that table) mapped due to foreign key or synonym.
For me the issue was with a column in that table which had mapping with another schema-table, and it was missing.ex, public-synonym.

Another alternative:
in the parent pom, use:
<properties>
<rootDir>${session.executionRootDirectory}</rootDir>
<properties>
In the children poms, you can reference this variable.
Main caveat: It forces you to always execute command from the main parent pom directory. Then if you want to run commands (test for example) only for some specific module, use this syntax:
mvn test --projects
The configuration of surefire to parametize a "path_to_test_data" variable may then be:

<version>${surefire.plugin.version}</version>
<configuration>
<systemPropertyVariables>
<path_to_test_data>${rootDir}/../testdata</path_to_test_data>
</systemPropertyVariables>
</configuration>

Angular cannot take HTML elements directly thereby you need to specify the element type by binding the above generic to it.
UPDATE::
This can also be done using ViewChild with #localvariable as shown here, as mentioned in here
<textarea #someVar id="tasknote"
name="tasknote"
[(ngModel)]="taskNote"
placeholder="{{ notePlaceholder }}"
style="background-color: pink"
(blur)="updateNote() ; noteEditMode = false " (click)="noteEditMode = false"> {{ todo.note }}
</textarea>
import {ElementRef,Renderer2} from '@angular/core';
@ViewChild('someVar') el:ElementRef;
constructor(private rd: Renderer2) {}
ngAfterViewInit() {
console.log(this.rd);
this.el.nativeElement.focus(); //<<<=====same as oldest way
}

Good luck finding a font that supports them all. Only one shows up in Windows 7 with Chrome.
NOTE: Not sure if the syntax I'm using in this answer was available when the older answers were written, but I think that this is a better approach on how to solve the example mentioned in this question.
I've had some issues related to this topic (overwriting interface properties), and this is how I'm handling it:
You can even use choose a default
value for the generic parameter as you can see in <T extends number | SOME_OBJECT = number>
type SOME_OBJECT = { foo: "bar" }
interface INTERFACE_A <T extends number | SOME_OBJECT = number> {
property: T;
}
type A_NUMBER = INTERFACE_A; // USES THE default = number TYPE. SAME AS INTERFACE_A<number>
type A_SOME_OBJECT = INTERFACE_A<SOME_OBJECT> // MAKES { property: SOME_OBJECT }
And this is the result:
const aNumber: A_NUMBER = {
property: 111 // THIS EXPECTS A NUMBER
}
const anObject: A_SOME_OBJECT = {
property: { // THIS EXPECTS SOME_OBJECT
foo: "bar"
}
}
If you dig deeper in android code, you can find the lines that clearly indicate, that we cannot change the duration of Toast message.
NotificationManagerService.scheduleTimeoutLocked() {
...
long delay = immediate ? 0 : (r.duration == Toast.LENGTH_LONG ? LONG_DELAY : SHORT_DELAY);
}
and default values for duration are
private static final int LONG_DELAY = 3500; // 3.5 seconds
private static final int SHORT_DELAY = 2000; // 2 seconds
Try making your constructor private like this:
private Foo newClass = new Foo();
Very quick and simple and does exactly what you want
svn status | awk '{if($2 !~ /(config|\.ini)/ && !system("test -e \"" $2 "\"")) {print $2; system("rm -Rf \"" $2 "\"");}}'
The /(config|.ini)/ is for my own purposes.
And might be a good idea to add --no-ignore to the svn command
SELECT username, salary
FROM tblname
GROUP by salary
ORDER by salary desc
LIMIT 0,1 ;
From the matplotlib documentation,
font = {'family' : 'normal',
'weight' : 'bold',
'size' : 22}
matplotlib.rc('font', **font)
This sets the font of all items to the font specified by the kwargs object, font
.
Alternatively, you could also use the rcParams
update
method as suggested in this answer:
matplotlib.rcParams.update({'font.size': 22})
or
import matplotlib.pyplot as plt
plt.rcParams.update({'font.size': 22})
You can find a full list of available properties on the Customizing matplotlib page.
While @roufamatic did show use of the arguments keyword and @Ken showed a great example of an object for usage I feel neither truly addressed what is going on in this instance and may confuse future readers or instill a bad practice as not explicitly stating a function/method is intended to take a variable amount of arguments/parameters.
function varyArg () {
return arguments[0] + arguments[1];
}
When another developer is looking through your code is it very easy to assume this function does not take parameters. Especially if that developer is not privy to the arguments keyword. Because of this it is a good idea to follow a style guideline and be consistent. I will be using Google's for all examples.
Let's explicitly state the same function has variable parameters:
function varyArg (var_args) {
return arguments[0] + arguments[1];
}
There may be times when an object is needed as it is the only approved and considered best practice method of an data map. Associative arrays are frowned upon and discouraged.
SIDENOTE: The arguments keyword actually returns back an object using numbers as the key. The prototypal inheritance is also the object family. See end of answer for proper array usage in JS
In this case we can explicitly state this also. Note: this naming convention is not provided by Google but is an example of explicit declaration of a param's type. This is important if you are looking to create a more strict typed pattern in your code.
function varyArg (args_obj) {
return args_obj.name+" "+args_obj.weight;
}
varyArg({name: "Brian", weight: 150});
This depends on your function's and program's needs. If for instance you are simply looking to return a value base on an iterative process across all arguments passed then most certainly stick with the arguments keyword. If you need definition to your arguments and mapping of the data then the object method is the way to go. Let's look at two examples and then we're done!
function sumOfAll (var_args) {
return arguments.reduce(function(a, b) {
return a + b;
}, 0);
}
sumOfAll(1,2,3); // returns 6
function myObjArgs(args_obj) {
// MAKE SURE ARGUMENT IS AN OBJECT OR ELSE RETURN
if (typeof args_obj !== "object") {
return "Arguments passed must be in object form!";
}
return "Hello "+args_obj.name+" I see you're "+args_obj.age+" years old.";
}
myObjArgs({name: "Brian", age: 31}); // returns 'Hello Brian I see you're 31 years old
As mentioned up top of the answer the arguments keyword actually returns an object. Because of this any method you want to use for an array will have to be called. An example of this:
Array.prototype.map.call(arguments, function (val, idx, arr) {});
To avoid this use the rest parameter:
function varyArgArr (...var_args) {
return var_args.sort();
}
varyArgArr(5,1,3); // returns 1, 3, 5
From See Java Static Variable Methods:
- It is a variable which belongs to the class and not to object(instance)
- Static variables are initialized only once , at the start of the execution. These variables will be initialized first, before the initialization of any instance variables
- A single copy to be shared by all instances of the class
- A static variable can be accessed directly by the class name and doesn’t need any object.
Instance and class (static) variables are automatically initialized to standard default values if you fail to purposely initialize them. Although local variables are not automatically initialized, you cannot compile a program that fails to either initialize a local variable or assign a value to that local variable before it is used.
What the compiler actually does is to internally produce a single class initialization routine that combines all the static variable initializers and all of the static initializer blocks of code, in the order that they appear in the class declaration. This single initialization procedure is run automatically, one time only, when the class is first loaded.
In case of inner classes, they can not have static fields
An inner class is a nested class that is not explicitly or implicitly declared
static
....
Inner classes may not declare static initializers (§8.7) or member interfaces...
Inner classes may not declare static members, unless they are constant variables...
See JLS 8.1.3 Inner Classes and Enclosing Instances
final
fields in Java can be initialized separately from their declaration place this is however can not be applicable to static final
fields. See the example below.
final class Demo
{
private final int x;
private static final int z; //must be initialized here.
static
{
z = 10; //It can be initialized here.
}
public Demo(int x)
{
this.x=x; //This is possible.
//z=15; compiler-error - can not assign a value to a final variable z
}
}
This is because there is just one copy of the static
variables associated with the type, rather than one associated with each instance of the type as with instance variables and if we try to initialize z
of type static final
within the constructor, it will attempt to reinitialize the static final
type field z
because the constructor is run on each instantiation of the class that must not occur to static final
fields.
Here is a sample script that I recently used in a Gateway POST transaction that receives a GET response. Are you using this in a custom C# form? Whatever your purpose, just replace the String fields (username, password, etc.) with the parameters from your form.
private String readHtmlPage(string url)
{
//setup some variables
String username = "demo";
String password = "password";
String firstname = "John";
String lastname = "Smith";
//setup some variables end
String result = "";
String strPost = "username="+username+"&password="+password+"&firstname="+firstname+"&lastname="+lastname;
StreamWriter myWriter = null;
HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url);
objRequest.Method = "POST";
objRequest.ContentLength = strPost.Length;
objRequest.ContentType = "application/x-www-form-urlencoded";
try
{
myWriter = new StreamWriter(objRequest.GetRequestStream());
myWriter.Write(strPost);
}
catch (Exception e)
{
return e.Message;
}
finally {
myWriter.Close();
}
HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();
using (StreamReader sr =
new StreamReader(objResponse.GetResponseStream()) )
{
result = sr.ReadToEnd();
// Close and clean up the StreamReader
sr.Close();
}
return result;
}

The problem was related to CORS. I noticed that there was another error in Chrome console:
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access. The response had HTTP status code 422.`
This means the response from backend server was missing Access-Control-Allow-Origin
header even though backend nginx was configured to add those headers to the responses with add_header
directive.
However, this directive only adds headers when response code is 20X or 30X. On error responses the headers were missing. I needed to use always
parameter to make sure header is added regardless of the response code:
add_header 'Access-Control-Allow-Origin' 'http://localhost:4200' always;
Once the backend was correctly configured I could access actual error message in Angular code.
My recipe of symmetric difference between two dictionaries:
def find_dict_diffs(dict1, dict2):
unequal_keys = []
unequal_keys.extend(set(dict1.keys()).symmetric_difference(set(dict2.keys())))
for k in dict1.keys():
if dict1.get(k, 'N\A') != dict2.get(k, 'N\A'):
unequal_keys.append(k)
if unequal_keys:
print 'param', 'dict1\t', 'dict2'
for k in set(unequal_keys):
print str(k)+'\t'+dict1.get(k, 'N\A')+'\t '+dict2.get(k, 'N\A')
else:
print 'Dicts are equal'
dict1 = {1:'a', 2:'b', 3:'c', 4:'d', 5:'e'}
dict2 = {1:'b', 2:'a', 3:'c', 4:'d', 6:'f'}
find_dict_diffs(dict1, dict2)
And result is:
param dict1 dict2
1 a b
2 b a
5 e N\A
6 N\A f

A Thread dump is a dump of all threads's stack traces, i.e. as if each Thread suddenly threw an Exception and printStackTrace'ed that. This is so that you can see what each thread is doing at some specific point, and is for example very good to catch deadlocks.
A heap dump is a "binary dump" of the full memory the JVM is using, and is for example useful if you need to know why you are running out of memory - in the heap dump you could for example see that you have one billion User objects, even though you should only have a thousand, which points to a memory retention problem.
Adding usefulness to @Dan's example, I had the need to find the next midday or midnight.
var d = new Date();
if(d.getHours() < 12) {
d.setHours(12,0,0,0); // next midnight/midday is midday
} else {
d.setHours(24,0,0,0); // next midnight/midday is midnight
}
This allowed me to set a frequency cap for an event, only allowing it to happen once in the morning and once in the afternoon for any visitor to my site. The date captured was used to set the expiration of the cookie.
By default you use UNICODE so I suggest using faulty's method
int bar = int.Parse(foo.ToString());
Even though the numeric values under are the same for digits and basic Latin chars.
As I understand, you want the average value for each id at each pass. The solution is
SELECT id, pass, avg(value) FROM data_r1
GROUP BY id, pass;
Basing on Ilya's data, I wrote a Vanilla JS library for supporting modifier keys on Mac: https://github.com/MichaelZelensky/jsLibraries/blob/master/macKeys.js
Just use it like this, e.g.:
document.onclick = function (event) {
if (event.shiftKey || macKeys.shiftKey) {
//do something interesting
}
}
Tested on Chrome, Safari, Firefox, Opera on Mac. Please check if it works for you.
One option is to put the subquery in a LEFT JOIN
:
select sum ( t.graduates ) - t1.summedGraduates
from table as t
left join
(
select sum ( graduates ) summedGraduates, id
from table
where group_code not in ('total', 'others' )
group by id
) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates
Perhaps a better option would be to use SUM
with CASE
:
select sum(case when group_code = 'total' then graduates end) -
sum(case when group_code not in ('total','others') then graduates end)
from yourtable

Note: Due to reputation I cannot comment on bdeem's post. I'm posting my findings as an answer instead.
Following bdeem's post, I did the following (in order):
1. I modified the [project].csproj
file. Added the <Content Include="" />
tags to the ItemGroup
for the different config
files and made them dependent on the original config
file.
Note: Using <None Include="" />
will not work with the transformation.
<!-- App.config Settings -->
<!-- Create App.($Configuration).config files here. -->
<Content Include="App.config" />
<Content Include="App.Debug.config">
<DependentUpon>App.config</DependentUpon>
</Content>
<Content Include="App.Release.config">
<DependentUpon>App.config</DependentUpon>
</Content>
2. At the bottom of the [project].csproj
file (before the closing </Project>
tag), I imported the ${MSBuildToolsPath\Microsoft.CSharp.targets
file, added the UsingTask
to transform the XML and added the Target
to copy the transformed App.config
file to the output location.
Note: The Target
will also overwrite the App.Config
in the local directory to see immediate changes working locally. The Target
also uses the Name="Afterbuild"
property to ensure the config files can be transformed after the executables are generated. For reasons I do not understand, when using WCF endpoints, if I use Name="CoreCompile"
, I will get warnings about the service attributes. Name="Afterbuild"
resolved this.
<!-- Task to transform the App.config using the App.($Configuration).config file. -->
<UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />
<!-- Only compile the App.config if the App.($Configuration).config file exists. -->
<!-- Make sure to use the AfterBuild name instead of CoreCompile to avoid first time build errors and WCF endpoint errors. -->
<Target Name="AfterBuild" Condition="exists('App.$(Configuration).config')">
<!-- Generate transformed App.config in the intermediate output directory -->
<TransformXml Source="App.config" Destination="$(IntermediateOutputPath)$(TargetFileName).config" Transform="App.$(Configuration).config" />
<!-- Modify the original App.config file with the transformed version. -->
<TransformXml Source="App.config" Destination="App.config" Transform="App.$(Configuration).config" />
<!-- Force build process to use the transformed configuration file from now on. -->
<ItemGroup>
<AppConfigWithTargetPath Remove="App.config" />
<AppConfigWithTargetPath Include="$(IntermediateOutputPath)$(TargetFileName).config">
<TargetPath>$(TargetFileName).config</TargetPath>
</AppConfigWithTargetPath>
</ItemGroup>
</Target>
</Project>
3. Went back into Visual Studio and reloaded the modified files.
4. Manually added the App.*.config
files to the project. This allowed them to group under the original App.config
file.
Note: Make sure the App.*.config
files have the proper XML structure.
<?xml version="1.0" encoding="utf-8"?>
<!-- For more information on using web.config transformation visit https://go.microsoft.com/fwlink/?LinkId=125889 -->
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<connectionStrings>
<add name="myConn" connectionString=""; Initial Catalog=; User ID=; Password=;" xdt:Transform="SetAttributes" xdt:Locator="Match(name)" />
</connectionStrings>
</configuration>
5. Re-built the project.
After the last Firefox update we had the same session timeout issue and the following setting helped to resolve it.
We can control it with network.http.response.timeout
parameter.
network.http.response.timeout
parameter will be displayed.network.http.response.timeout
parameter and enter the time value (it is in seconds) that you don't want your session not to timeout, in the box.@agstudy's answer didn't work for me with the latest version of ggplot2
, but this did, using maggritr
pipes:
ggplot(data=dat)+
geom_line(aes(Value1, Value2, group=ID, colour=ID),
data = . %>% filter(ID %in% c("P1" , "P3")))
It works because if geom_line
sees that data
is a function, it will call that function with the inherited version of data
and use the output of that function as data
.
try it like this:
function popupwindow(url, title, w, h) {
var left = (screen.width/2)-(w/2);
var top = (screen.height/2)-(h/2);
return window.open(url, title, 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width='+w+', height='+h+', top='+top+', left='+left);
}
While I agree with others that direct use of an iterable container is a preferred solution, I want to point out that the C++ standard guarantees enough support for a do-it-yourself solution in case you want it for whatever reason.
Namely, you can inherit from std::queue
and use its protected member Container c;
to access begin() and end() of the underlying container (provided that such methods exist there). Here is an example that works in VS 2010 and tested with ideone:
#include <queue>
#include <deque>
#include <iostream>
template<typename T, typename Container=std::deque<T> >
class iterable_queue : public std::queue<T,Container>
{
public:
typedef typename Container::iterator iterator;
typedef typename Container::const_iterator const_iterator;
iterator begin() { return this->c.begin(); }
iterator end() { return this->c.end(); }
const_iterator begin() const { return this->c.begin(); }
const_iterator end() const { return this->c.end(); }
};
int main() {
iterable_queue<int> int_queue;
for(int i=0; i<10; ++i)
int_queue.push(i);
for(auto it=int_queue.begin(); it!=int_queue.end();++it)
std::cout << *it << "\n";
return 0;
}
.svn
's parent directoryjust this steps helped me to resolve:
svn: E155004: Working copy 'resourceAddress' locked
The problem for me was as simple as just not knowing Javascript well. I was trying to pass the name of the id using double quotes, when I should have been using single. And it worked fine.
This worked:
validateSelectizeDropdown('#PartCondition')
This did not:
validateSelectizeDropdown("#PartCondition")
And the function:
function validateSelectizeDropdown(name) {
if ($(name).val() === "") {
//do something
}
}
If you want the variable inside the function available outside of the function, return the results of the variable inside the function.
var x = function returnX { var x = 0; return x; }
is the idea...

I haven't tested this, but if your code worked prior to that small change, then it should work.
You can also use the getJSON function:
$.getJSON('/your/script.php', function(data) {
$.each(data, function(index) {
alert(data[index].TEST1);
alert(data[index].TEST2);
});
});
This is really just a rewording of ifesdjeen's answer, but I thought it might be helpful to people.
minlength
attribute is now widely supported in most of the browsers.
<input type="text" minlength="2" required>
But, as with other HTML5 features, IE11 is missing from this panorama. So, if you have a wide IE11 user base, consider using the pattern
HTML5 attribute that is supported almost across the board in most browsers (including IE11).
To have a nice and uniform implementation and maybe extensible or dynamic (based on the framework that generate your HTML), I would vote for the pattern
attribute:
<input type="text" pattern=".{2,}" required>
There is still a small usability catch when using pattern
. The user will see a non-intuitive (very generic) error/warning message when using pattern
. See this jsfiddle or below:
<h3>In each form type 1 character and press submit</h3>_x000D_
</h2>_x000D_
<form action="#">_x000D_
Input with minlength: <input type="text" minlength="2" required name="i1">_x000D_
<input type="submit" value="Submit">_x000D_
</form>_x000D_
<br>_x000D_
<form action="#">_x000D_
Input with patern: <input type="text" pattern=".{2,}" required name="i1">_x000D_
<input type="submit" value="Submit">_x000D_
</form>
_x000D_
For example, in Chrome (but similar in most browsers), you will get the following error messages:
Please lengthen this text to 2 characters or more (you are currently using 1 character)
by using minlength
and
Please match the format requested
by using pattern
.
this.data
presumably contains all the data, so you would need to do something like this:
var stations = [];
var stationData = this.data.stations;
for (var i = 0; i < stationData.length; i++) {
stations.push(
<div key={stationData[i].call} className="station">
Call: {stationData[i].call}, Freq: {stationData[i].frequency}
</div>
)
}
render() {
return (
<div className="stations">{stations}</div>
)
}
Or you can use map
and arrow functions if you're using ES6:
const stations = this.data.stations.map(station =>
<div key={station.call} className="station">
Call: {station.call}, Freq: {station.frequency}
</div>
);
Constructor looks like a method but name should be as class name and no return value.
Overriding means what we have declared in Super class, that exactly we have to declare in Sub class it is called Overriding. Super class name and Sub class names are different.
If you trying to write Super class Constructor in Sub class, then Sub class will treat that as a method not constructor because name should not match with Sub class name. And it will give an compilation error that methods does not have return value. So we should declare as void, then only it will compile.
The shortest version:
var myArray = ['January', 'February', 'March'];
var rand = myArray[(Math.random() * myArray.length) | 0]
If the file is a .dll then you can use the TaskList command line app to see whose got it open:

Class Parent cannot be declared because it is PHP reserved keyword so in effect it's already in use

Although this is almost certainly not the OPs issue, you can also get Unable to establish SSL connection
from wget
if you're behind a proxy and don't have HTTP_PROXY
and HTTPS_PROXY
environment variables set correctly. Make sure to set HTTP_PROXY
and HTTPS_PROXY
to point to your proxy.
This is a common situation if you work for a large corporation.
IF EXISTS()
is semantically incorrect. EXISTS
condition can be used only inside a SQL statement. So you might rewrite your pl/sql block as follows:
declare
l_exst number(1);
begin
select case
when exists(select ce.s_regno
from courseoffering co
join co_enrolment ce
on ce.co_id = co.co_id
where ce.s_regno=403
and ce.coe_completionstatus = 'C'
and ce.c_id = 803
and rownum = 1
)
then 1
else 0
end into l_exst
from dual;
if l_exst = 1
then
DBMS_OUTPUT.put_line('YES YOU CAN');
else
DBMS_OUTPUT.put_line('YOU CANNOT');
end if;
end;
Or you can simply use count
function do determine the number of rows returned by the query, and rownum=1
predicate - you only need to know if a record exists:
declare
l_exst number;
begin
select count(*)
into l_exst
from courseoffering co
join co_enrolment ce
on ce.co_id = co.co_id
where ce.s_regno=403
and ce.coe_completionstatus = 'C'
and ce.c_id = 803
and rownum = 1;
if l_exst = 0
then
DBMS_OUTPUT.put_line('YOU CANNOT');
else
DBMS_OUTPUT.put_line('YES YOU CAN');
end if;
end;
There's a setting in Safari under "Tabs" that labeled Open pages in tabs instead of windows:
with a drop down with a few options. I'm thinking yours may be set to Always
. Bottom line is you can't rely on a browser opening a new window.
Well , it might help someone. i just got the same error while my json file is like this
{"id":"1101010","city_id":"1101","name":"TEUPAH SELATAN"}
{"id":"1101020","city_id":"1101","name":"SIMEULUE TIMUR"}
and i found it malformed, so i changed it into somekind of
{
"datas":[
{"id":"1101010","city_id":"1101","name":"TEUPAH SELATAN"},
{"id":"1101020","city_id":"1101","name":"SIMEULUE TIMUR"}
]
}
You may try creating a new project in netbeans and then copy and and paste the files into it. I usually experience this problem when the project wasn't created in netbeans.
If I recall correctly, a div inside a li used to be invalid.
@Flower @Superstringcheese Div should semantically define a section of a document, but it has already practically lost this role. Span should however contain text.
You have 4 columns A,B,C,D
Here is a better way to select the columns you need for the new dataframe:-
df2 = df1[['A','D']]
if you wish to use column numbers instead, use:-
df2 = df1[[0,3]]
You can do that just using CSS.
You'll need to place another tag inside the <a>
and then you can change the CSS background-image
attribute on a:hover
.
i.e.
HTML:
<a href="#" id="name">
<span> </span>
</a>
CSS:
a#name span{
background-image:url(image/path);
}
a#name:hover span{
background-image:url(another/image/path);
}
How about reinstalling the node module? Go to the root directory
of the project and remove the current node modules
and install again.
These are the commands : rm -rf node_modules npm install
OR
npm uninstall -g react-native-cli
and
npm install -g react-native-cli
Maybe a little late, but I found an easier way to set the defaults! You have to right-click on the right of your tab and choose "size", then click on your window, and it should keep it as the default size.
go to AndroidManifest.xml and change the android:icon="@mipmap/ic_launcher" to android:icon="@mipmap/(your image name)" suppose you have a image named telugu and you want it to be set as your app icon then change android:icon="@mipmap/telugu" and you have to copy and paste your image into mipmap folder thats it its so simple as i said
To somewhat expand on earlier answers, there are a few complications.
telnet
is not particularly scriptable; you might prefer to use nc
(aka netcat
) instead, which handles non-terminal input and signals better.
Also, unlike telnet
, nc
actually allows SSL (and so https
instead of http
traffic -- you need port 443 instead of port 80 then).
There is a difference between HTTP 1.0 and 1.1. The recent version of the protocol requires the Host:
header to be included in the request on a separate line after the POST
or GET
line, and to be followed by an empty line to mark the end of the request headers.
The HTTP protocol requires carriage return / line feed line endings. Many servers are lenient about this, but some are not. You might want to use
printf "%\r\n" \
"GET /questions HTTP/1.1" \
"Host: stackoverflow.com" \
"" |
nc --ssl stackoverflow.com 443
If you fall back to HTTP/1.0 you don't always need the Host:
header, but many modern servers require the header anyway; if multiple sites are hosted on the same IP address, the server doesn't know from GET /foo HTTP/1.0
whether you mean http://site1.example.com/foo
or http://site2.example.net/foo
if those two sites are both hosted on the same server (in the absence of a Host:
header, a HTTP 1.0 server might just default to a different site than the one you want, so you don't get the contents you wanted).
The HTTPS protocol is identical to HTTP in these details; the only real difference is in how the session is set up initially.
Your -vm argument seems ok BUT it's position is wrong. According to this Eclipse Wiki entry :
The -vm option must occur before the -vmargs option, since everything after -vmargs is passed directly to the JVM.
So your -vm argument is not taken into account and it fails over to your default java installation, which is probably 1.6.0_65.
I am all for Eran Harel's solution and in cases where it isn't possible, Tomasz Nurkiewicz's suggestion for spying is excellent. However, it's worth noting that there are situations where neither would apply. E.g. if the login
method was a bit "beefier":
public class TestedClass {
public LoginContext login(String user, String password) {
LoginContext lc = new LoginContext("login", callbackHandler);
lc.doThis();
lc.doThat();
return lc;
}
}
... and this was old code that could not be refactored to extract the initialization of a new LoginContext
to its own method and apply one of the aforementioned solutions.
For completeness' sake, it's worth mentioning a third technique - using PowerMock to inject the mock object when the new
operator is called. PowerMock isn't a silver bullet, though. It works by applying byte-code manipulation on the classes it mocks, which could be dodgy practice if the tested classes employ byte code manipulation or reflection and at least from my personal experience, has been known to introduce a performance hit to the test. Then again, if there are no other options, the only option must be the good option:
@RunWith(PowerMockRunner.class)
@PrepareForTest(TestedClass.class)
public class TestedClassTest {
@Test
public void testLogin() {
LoginContext lcMock = mock(LoginContext.class);
whenNew(LoginContext.class).withArguments(anyString(), anyString()).thenReturn(lcMock);
TestedClass tc = new TestedClass();
tc.login ("something", "something else");
// test the login's logic
}
}
set environment variable in deployment server(ex: like NODE_ENV=production). You can access your environmental variable through process.env.NODE_ENV. Find the following config file for the global settings
const env = process.env.NODE_ENV || "development"
const configs = {
base: {
env,
host: '0.0.0.0',
port: 3000,
dbPort: 3306,
secret: "secretKey for sessions",
dialect: 'mysql',
issuer : 'Mysoft corp',
subject : '[email protected]',
},
development: {
port: 3000,
dbUser: 'root',
dbPassword: 'root',
},
smoke: {
port: 3000,
dbUser: 'root',
},
integration: {
port: 3000,
dbUser: 'root',
},
production: {
port: 3000,
dbUser: 'root',
}
};
const config = Object.assign(configs.base, configs[env]);
module.exports= config;
base contains common config for all environments.
then import in other modules like
const config = require('path/to/config.js')
console.log(config.port)
Happy Coding...
I think this is the easy way to open a URL using this function
webbrowser.open_new_tab(url)
I've used this function several times:
public static bool IsNumeric(object Expression)
{
double retNum;
bool isNum = Double.TryParse(Convert.ToString(Expression), System.Globalization.NumberStyles.Any, System.Globalization.NumberFormatInfo.InvariantInfo, out retNum);
return isNum;
}
But you can also use;
bool b1 = Microsoft.VisualBasic.Information.IsNumeric("1"); //true
bool b2 = Microsoft.VisualBasic.Information.IsNumeric("1aa"); // false

To make it work, I installed latex, typical latex extra, and pandoc.
With ubuntu:
sudo apt-get install texlive texlive-latex-extra pandoc
it takes some times: several 100 Mb to download. I read somewhere that you can use --no-install-recommends
for texlive and extra to reduce to the dl.
This probably isn't relevant any more to this thread, but hopefully helpful to somebody. I've had 500 errors for the past hour as I had a controller return an array not supported by the php version ran on my (crappy) server. Seems trivial but had the hallmarks of a codeigniter error.
I had to use:
class emck_model extends CI_Model {
public function getTiles(){
return array(...);
}
}
Instead of
class emck_model extends CI_Model {
public function getTiles(){
return [...];
}
}

It's a Bash feature called "tilde expansion". It's a function of the shell, not the OS. You'll get different behavior with csh, for example.
To answer your question about where the information comes from: your home directory comes from the variable $HOME
(no matter what you store there), while other user's homes are retrieved real-time using getpwent()
. This function is usually controlled by NSS; so by default values are pulled out of /etc/passwd
, though it can be configured to retrieve the information using any source desired, such as NIS, LDAP or an SQL database.
Tilde expansion is more than home directory lookup. Here's a summary:
~ $HOME
~fred (freds home dir)
~+ $PWD (your current working directory)
~- $OLDPWD (your previous directory)
~1 `dirs +1`
~2 `dirs +2`
~-1 `dirs -1`
dirs
and ~1
, ~-1
, etc., are used in conjunction with pushd
and popd
.
Use chown
to change ownership and chmod
to change rights.
use the -R
option to apply the rights for all files inside of a directory too.
Note that both these commands just work for directories too. The -R
option makes them also change the permissions for all files and directories inside of the directory.
For example
sudo chown -R username:group directory
will change ownership (both user and group) of all files and directories inside of directory and directory itself.
sudo chown username:group directory
will only change the permission of the folder directory but will leave the files and folders inside the directory alone.
you need to use sudo to change the ownership from root to yourself.
Edit:
Note that if you use chown user: file
(Note the left-out group), it will use the default group for that user.
Also You can change the group ownership of a file or directory with the command:
chgrp group_name file/directory_name
You must be a member of the group to which you are changing ownership to.
You can find group of file as follows
# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file
# chown sujit:friends file
User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.
What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.
But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.
Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

For those using the Symfony framework, the phpseclib can also be used to connect via SSH. It can be installed using composer:
composer require phpseclib/phpseclib
Next, simply use it as follows:
use phpseclib\Net\SSH2;
// Within a controller for example:
$ssh = new SSH2('hostname or ip');
if (!$ssh->login('username', 'password')) {
// Login failed, do something
}
$return_value = $ssh->exec('command');
This is the solution I use. It has more lines but it will only create the datepicker once.
$('#txtSearch').datepicker({
constrainInput:false,
beforeShow: function(){
var t = $('#ddlSearchType').val();
if( ['Required Date', 'Submitted Date'].indexOf(t) ) {
$('#txtSearch').prop('readonly', false);
return false;
}
else $('#txtSearch').prop('readonly', true);
}
});
The datepicker will not show unless the value of ddlSearchType is either "Required Date" or "Submitted Date"
Simple example:
var userID = data.id;
localStorage.setItem('userID',JSON.stringify(userID));
A quick benchmark:
import collections
import itertools
def count_iter_items(iterable):
counter = itertools.count()
collections.deque(itertools.izip(iterable, counter), maxlen=0)
return next(counter)
def count_lencheck(iterable):
if hasattr(iterable, '__len__'):
return len(iterable)
d = collections.deque(enumerate(iterable, 1), maxlen=1)
return d[0][0] if d else 0
def count_sum(iterable):
return sum(1 for _ in iterable)
iter = lambda y: (x for x in xrange(y))
%timeit count_iter_items(iter(1000))
%timeit count_lencheck(iter(1000))
%timeit count_sum(iter(1000))
The results:
10000 loops, best of 3: 37.2 µs per loop
10000 loops, best of 3: 47.6 µs per loop
10000 loops, best of 3: 61 µs per loop
I.e. the simple count_iter_items is the way to go.
Adjusting this for python3:
61.9 µs ± 275 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)
74.4 µs ± 190 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)
82.6 µs ± 164 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)
try use CMAKE_GENERATOR_PLATFORM
e.g.
// x86
cmake -DCMAKE_GENERATOR_PLATFORM=x86 .
// x64
cmake -DCMAKE_GENERATOR_PLATFORM=x64 .
function UniqueValue(d){
var dat_e = new Date();
var uniqu_e = ((Math.random() *1000) +"").slice(-4)
dat_e = dat_e.toISOString().replace(/[^0-9]/g, "").replace(dat_e.getFullYear(),uniqu_e);
if(d==dat_e)
dat_e = UniqueValue(dat_e);
return dat_e;
}
Call 1: UniqueValue('0')
Call 2: UniqueValue(UniqueValue('0')) // will be complex
Sample Output:
for(var i =0;i<10;i++){ console.log(UniqueValue(UniqueValue('0')));}

Sorry this is and old thread but some people would still need this I guess,
Note: I achieved this using Animate.css library for animating the fade.
I used your code and just added .hidden class (using bootstrap's hidden class) but you can still just define
.hidden { opacity: 0; }
$(document).ready(function() {
/* Every time the window is scrolled ... */
$(window).scroll( function(){
/* Check the location of each desired element */
$('.hideme').each( function(i){
var bottom_of_object = $(this).position().top + $(this).outerHeight();
var bottom_of_window = $(window).scrollTop() + $(window).height();
/* If the object is completely visible in the window, fade it it */
if( bottom_of_window > bottom_of_object ){
$(this).removeClass('hidden');
$(this).addClass('animated fadeInUp');
} else {
$(this).addClass('hidden');
}
});
});
});
Another Note: Applying this to containers might cause it to be glitchy.
update VersionedFields
set Value = replace(replace(value,'<iframe','<a>iframe'), '> </iframe>','</a>')
and you do it in a single pass.
"So does it mean definition equals declaration plus initialization."
Not necessarily, your declaration might be without any variable being initialized like:
void helloWorld(); //declaration or Prototype.
void helloWorld()
{
std::cout << "Hello World\n";
}
I would have to say SimpleXML takes the cake because it is firstly an extension, written in C, and is very fast. But second, the parsed document takes the form of a PHP object. So you can "query" like $root->myElement
.
break
will exit the loop, while continue
will start the next cycle of the loop immediately.
DateTime unixEpoch = DateTime.ParseExact("1970-01-01", "yyyy-MM-dd", System.Globalization.CultureInfo.InvariantCulture);
DateTime convertedTime = unixEpoch.AddMilliseconds(unixTimeInMillisconds);
Of course, one can make unixEpoch
a global static, so it only needs to appear once in your project, and one can use AddSeconds
if the UNIX time is in seconds.
To go the other way:
double unixTimeInMilliseconds = timeToConvert.Subtract(unixEpoch).TotalMilliseconds;
Truncate to Int64 and/or use TotalSeconds
as needed.
By default, an inline definition is only valid in the current translation unit.
If the storage class is extern
, the identifier has external linkage and the inline definition also provides the external definition.
If the storage class is static
, the identifier has internal linkage and the inline definition is invisible in other translation units.
If the storage class is unspecified, the inline definition is only visible in the current translation unit, but the identifier still has external linkage and an external definition must be provided in a different translation unit. The compiler is free to use either the inline or the external definition if the function is called within the current translation unit.
As the compiler is free to inline (and to not inline) any function whose definition is visible in the current translation unit (and, thanks to link-time optimizations, even in different translation units, though the C standard doesn't really account for that), for most practical purposes, there's no difference between static
and static inline
function definitions.
The inline
specifier (like the register
storage class) is only a compiler hint, and the compiler is free to completely ignore it. Standards-compliant non-optimizing compilers only have to honor their side-effects, and optimizing compilers will do these optimizations with or without explicit hints.
inline
and register
are not useless, though, as they instruct the compiler to throw errors when the programmer writes code that would make the optimizations impossible: An external inline
definition can't reference identifiers with internal linkage (as these would be unavailable in a different translation unit) or define modifiable local variables with static storage duration (as these wouldn't share state accross translation units), and you can't take addresses of register
-qualified variables.
Personally, I use the convention to mark static
function definitions within headers also inline
, as the main reason for putting function definitions in header files is to make them inlinable.
In general, I only use static inline
function and static const
object definitions in addition to extern
declarations within headers.
I've never written an inline
function with a storage class different from static
.
All of this works for me:

Echo Bat File Drive = %~d0
Echo Full File Name = %~n0%~x0
Echo File Name Without Extension = %~n0
Echo File Extension = %~x0

Output:

You need to specify the master for the second button. Otherwise it will get packed onto the first window. This is needed not only for Button
, but also for other widgets and non-gui objects such as StringVar
.
Quick fix: add the frame new
as the first argument to your Button
in Demo2
.
Possibly better: Currently you have Demo2
inheriting from tk.Frame
but I think this makes more sense if you change Demo2
to be something like this,
class Demo2(tk.Toplevel):
def __init__(self):
tk.Toplevel.__init__(self)
self.title("Demo 2")
self.button = tk.Button(self, text="Button 2", # specified self as master
width=25, command=self.close_window)
self.button.pack()
def close_window(self):
self.destroy()
Just as a suggestion, you should only import tkinter
once. Pick one of your first two import statements.
I did a search, which requires you to input a certain value, then it will look for a value from the list which contains your input:
my_list = ['abc-123',
'def-456',
'ghi-789',
'abc-456'
]
imp = raw_input('Search item: ')
for items in my_list:
val = items
if any(imp in val for items in my_list):
print(items)
Try searching for 'abc'.
Your HTTP client disconnected.
This could have a couple of reasons:
You can fairly easily emulate the behavior:
URL url = new URL("http://example.com/path/to/the/file");
int numberOfBytesToRead = 200;
byte[] buffer = new byte[numberOfBytesToRead];
int numberOfBytesRead = url.openStream().read(buffer);
Use the below code to find the count of number of matches that the regex finds in your input
Pattern p = Pattern.compile(regex, Pattern.MULTILINE | Pattern.DOTALL);// "regex" here indicates your predefined regex.
Matcher m = p.matcher(pattern); // "pattern" indicates your string to match the pattern against with
boolean b = m.matches();
if(b)
count++;
while (m.find())
count++;
This is a generalized code not specific one though, tailor it to suit your need
Please feel free to correct me if there is any mistake.
if you are dealing with currency values and formatting a lot then it might be worth to add tiny accounting.js which handles lot of edge cases and localization:
// Default usage:
accounting.formatMoney(12345678); // $12,345,678.00
// European formatting (custom symbol and separators), could also use options object as second param:
accounting.formatMoney(4999.99, "€", 2, ".", ","); // €4.999,99
// Negative values are formatted nicely, too:
accounting.formatMoney(-500000, "£ ", 0); // £ -500,000
// Simple `format` string allows control of symbol position [%v = value, %s = symbol]:
accounting.formatMoney(5318008, { symbol: "GBP", format: "%v %s" }); // 5,318,008.00 GBP

@AHegde - To get the tab delimited output use separator sep='\t'.
For df.to_csv:
df.to_csv(r'c:\data\pandas.txt', header=None, index=None, sep='\t', mode='a')
For np.savetxt:
np.savetxt(r'c:\data\np.txt', df.values, fmt='%d', delimiter='\t')
Here we use w+ for read/write both actions and if the file path is not found the it would be created automatically.
fs.open(path, 'w+', function(err, data) {
if (err) {
console.log("ERROR !! " + err);
} else {
fs.write(data, 'content', 0, 'content length', null, function(err) {
if (err)
console.log("ERROR !! " + err);
fs.close(data, function() {
console.log('written success');
})
});
}
});
Content means what you have to write to the file and its length, 'content.length'.
A slight variation on the above simplified approach.
var result = yyy.Distinct().Count() == yyy.Count();
If you don't care about the ordering of the keys, you could do the following:
$array = YOUR_ARRAY
$unique = array();
foreach ($array as $a) {
$unique[$a] = $a;
}
Another idea is to use a setting in the Shared Preferences. Same general idea as checking for an empty file, but then you don't have an empty file floating around, not being used to store anything
Other answers are probably simpler for this case, but for completeness I thought I would add the use of cellfun with an anonymous function
indices = find(cellfun(@(x) strcmp(x,'KU'), strs))
which has the advantage that you can easily make it case insensitive or use it in cases where you have cell array of structures:
indices = find(cellfun(@(x) strcmpi(x.stringfield,'KU'), strs))
<div class="control-group">
<label class="control-label" for="firstname">First Name</label>
<div class="controls">
<input type="text" id="firstname" name="firstname"/>
</div>
</div>
Also we can use it Simply as
<label>First name:
<input type="text" id="firstname" name="firstname"/>
</label>
You could try this also.
Frame frame = new Frame("Centered Frame");
Dimension dimemsion = Toolkit.getDefaultToolkit().getScreenSize();
frame.setLocation(dimemsion.width/2-frame.getSize().width/2, dimemsion.height/2-frame.getSize().height/2);
You can use the "title attribute" for label tag.
<label title="Hello This Will Have Some Value">Hello...</label>
If you need more control over the looks,
1 . try http://getbootstrap.com/javascript/#tooltips as shown below. But you will need to include bootstrap.
<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="left" title="Hello This Will Have Some Value">Hello...</button>
2 . try https://jqueryui.com/tooltip/. But you will need to include jQueryUI.
<script type="text/javascript">
$(document).ready(function(){
$(this).tooltip();
});
</script>
Try jquery debugger plugin if you're using chrome: https://chrome.google.com/webstore/detail/jquery-debugger/dbhhnnnpaeobfddmlalhnehgclcmjimi?hl=en
You have a numpy array of strings, not floats. This is what is meant by dtype('<U9')
-- a little endian encoded unicode string with up to 9 characters.
try:
return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))
However, you don't need numpy here at all. You can really just do:
return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)
Or if you're really set on using numpy.
return np.asarray(listOfEmb, dtype=float).mean()
I think you are wrapping your exception in another exception (which isn't in your code above). If you try out this code:
public static void main(String[] args) {
try {
throw new RuntimeException("Cannot move file");
} catch (Exception ex) {
JOptionPane.showMessageDialog(null, "Error: " + ex.getMessage());
}
}
...you will see a popup that says exactly what you want.
However, to solve your problem (the wrapped exception) you need get to the "root" exception with the "correct" message. To do this you need to create a own recursive method getRootCause
:
public static void main(String[] args) {
try {
throw new Exception(new RuntimeException("Cannot move file"));
} catch (Exception ex) {
JOptionPane.showMessageDialog(null,
"Error: " + getRootCause(ex).getMessage());
}
}
public static Throwable getRootCause(Throwable throwable) {
if (throwable.getCause() != null)
return getRootCause(throwable.getCause());
return throwable;
}
Note: Unwrapping exceptions like this however, sort of breaks the abstractions. I encourage you to find out why the exception is wrapped and ask yourself if it makes sense.
Here is another method.
For react-router v4 you can also bind a listener to change in history event, in the following manner:
let firstMount = true;
const App = (props) => {
if (typeof window != 'undefined') { //incase you have server-side rendering too
firstMount && props.history.listen((location, action) => {
setImmediate(() => window.scrollTo(0, 0)); // ive explained why i used setImmediate below
});
firstMount = false;
}
return (
<div>
<MyHeader/>
<Switch>
<Route path='/' exact={true} component={IndexPage} />
<Route path='/other' component={OtherPage} />
// ...
</Switch>
<MyFooter/>
</div>
);
}
//mounting app:
render((<BrowserRouter><Route component={App} /></BrowserRouter>), document.getElementById('root'));
The scroll level will be set to 0 without setImmediate()
too if the route is changed by clicking on a link but if user presses back button on browser then it will not work as browser reset the scroll level manually to the previous level when the back button is pressed, so by using setImmediate()
we cause our function to be executed after browser is finished resetting the scroll level thus giving us the desired effect.
Switch to some other branch and delete Test_Branch
, as follows:
$ git checkout master
$ git branch -d Test_Branch
If above command gives you error - The branch 'Test_Branch' is not fully merged. If you are sure you want to delete it
and still you want to delete it, then you can force delete it using -D
instead of -d
, as:
$ git branch -D Test_Branch
To delete Test_Branch
from remote as well, execute:
git push origin --delete Test_Branch
You can use function: wc_get_page_id( 'cart' ) to get the ID of the page. This function will use the page setup as 'cart' page and not the slug. Meaning it will keep working also when you setup a different url for your 'cart' on the settings page. This works for all kind of Woocommerce special page, like 'checkout', 'shop' etc.
example:
if (wc_get_page_id( 'cart' ) == get_the_ID()) {
// Do something.
}
I had same problem. In "Edit Configurations.." -> "Tomcat Server" I changed JRE from "Default" to my current version with SDK directory address (like C:\Program Files\Java\jdk1.8.0_121\jre)
My Tomcat version is 8.5.31
I was solving same problem recently. I was designing a write cmdlet for my Subtitle module. I had six different user stories:
I end up in the big frustration because I though that 4 parameters will be enough. Like most of the times, the frustration was pointless because it was my fault. I didn't know enough about parameter sets.
After some research in documentation, I realized where is the problem. With knowledge how the parameter sets should be used, I developed a general and simple approach how to solve this problem. A pencil and a sheet of paper is required but a spreadsheet editor is better:
Example:
The practical example could be seen over here.
BTW: The parameter uniqueness within parameter sets is the reason why the ParameterSetName
property doesn't support [String[]]
. It doesn't really make any sense.
In Access, you will probably find a Join is quicker unless your tables are very small:
SELECT DISTINCT Table1.Column1
FROM Table1
LEFT JOIN Table2
ON Table1.Column1 = Table2.Column1
WHERE Table2.Column1 Is Null
This will exclude from the list all records with a match in Table2.
None of these worked for me in Ubuntu 16.4.
I came across this one that is written in java javaANPR, I am looking for a c# library as well.
I would like a system where I can point a video camera at some sailing boats, all of which have large, identifiable numbers on them, and have it identify the boats and send a tweet when they sail past a video camera.
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.setWindowTitle("Main Page");
w.show();
return a.exec();

You can just use mkdir
and catch the error if the folder exists.
This is async (so best practice) and safe.
fs.mkdir('/path', err => {
if (err && err.code != 'EEXIST') throw 'up'
.. safely do your stuff here
})
(Optionally add a second argument with the mode.)
Other thoughts:
You could use then or await by using native promisify.
const util = require('util'), fs = require('fs');
const mkdir = util.promisify(fs.mkdir);
var myFunc = () => { ..do something.. }
mkdir('/path')
.then(myFunc)
.catch(err => { if (err.code != 'EEXIST') throw err; myFunc() })
You can make your own promise method, something like (untested):
let mkdirAsync = (path, mode) => new Promise(
(resolve, reject) => mkdir (path, mode,
err => (err && err.code !== 'EEXIST') ? reject(err) : resolve()
)
)
For synchronous checking, you can use:
fs.existsSync(path) || fs.mkdirSync(path)
Or you can use a library, the two most popular being
if anyone is interested to use the cURL for validation. You can use the following code.
<?php
public function validationUrl($Url){
if ($Url == NULL){
return $false;
}
$ch = curl_init($Url);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
return ($httpcode >= 200 && $httpcode < 300) ? true : false;
}
Math.Floor() :
It gives the largest integer less than or equal to the given number.
Math.Floor(3.45) =3
Math.Floor(-3.45) =-4
Math.Truncate():
It removes the decimal places of the number and replace with zero
Math.Truncate(3.45)=3
Math.Truncate(-3.45)=-3
Also from above examples we can see that floor and truncate are same for positive numbers.
you need to give:
public void onActivityCreated(Bundle savedInstanceState)
{
super.onActivityCreated(savedInstanceState);
}
inside fragment.
I had a similar issue and solved after running these instructions!

Just thought I'd add my solution below, since the answers above did not meet my exact needs. My Xml schema required seperate Date and Time elements, not a singe DateTime field. The standard XMLGregorianCalendar constructor used above will generate a DateTime field
Note there a couple of gothca's, such as having to add one to the month (since java counts months from 0).
GregorianCalendar cal = new GregorianCalendar();
cal.setTime(yourDate);
XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance().newXMLGregorianCalendarDate(cal.get(Calendar.YEAR), cal.get(Calendar.MONTH)+1, cal.get(Calendar.DAY_OF_MONTH), 0);
XMLGregorianCalendar xmlTime = DatatypeFactory.newInstance().newXMLGregorianCalendarTime(cal.get(Calendar.HOUR_OF_DAY), cal.get(Calendar.MINUTE), cal.get(Calendar.SECOND), 0);
Use LinkedHashMap
:
Hash table and linked list implementation of the Map interface, with predictable iteration order. This implementation differs from HashMap in that it maintains a doubly-linked list running through all of its entries.
With an (optional) footerView
and contentInset
, the solution is:
CGPoint bottomOffset = CGPointMake(0, _tableView.contentSize.height - tableView.frame.size.height + _tableView.contentInset.bottom);
if (bottomOffset.y > 0) [_tableView setContentOffset: bottomOffset animated: YES];
A.splice(0);
I just did this on some code I am working on. It cleared the array.
Try this it might solve your problem.

I don't understand the concept of storing encrypted stuff in a cookie when it is the encrypted version of it that you need to do your hacking. If I'm missing something, please comment.
I am thinking about taking this approach to 'Remember Me'. If you can see any issues, please comment.
Create a table to store "Remember Me" data in - separate to the user table so that I can log in from multiple devices.
On successful login (with Remember Me ticked):
a) Generate a unique random string to be used as the UserID on this machine: bigUserID
b) Generate a unique random string: bigKey
c) Store a cookie: bigUserID:bigKey
d) In the "Remember Me" table, add a record with: UserID, IP Address, bigUserID, bigKey
If trying to access something that requires login:
a) Check for the cookie and search for bigUserID & bigKey with a matching IP address
b) If you find it, Log the person in but set a flag in the user table "soft login" so that for any dangerous operations, you can prompt for a full login.
On logout, Mark all the "Remember Me" records for that user as expired.

Yes, it is possible to run PowerShell through the run window. However, it would be burdensome and you will need to enter in the password for computer. This is similar to how you will need to set up when you run cmd:
runas /user:(ComputerName)\(local admin) powershell.exe
So a basic example would be:
runas /user:MyLaptop\[email protected] powershell.exe
You can find more information on this subject in Runas.
However, you could also do one more thing :
then your system will execute the elevated powershell.
I prefer httpclient over Net::HTTP.
client = HTTPClient.new
puts client.get_content('http://www.example.com/index.html')
HTTParty is a good choice if you're making a class that's a client for a service. It's a convenient mixin that gives you 90% of what you need. See how short the Google and Twitter clients are in the examples.
And to answer your second question: no, I wouldn't put this functionality in a controller--I'd use a model instead if possible to encapsulate the particulars (perhaps using HTTParty) and simply call it from the controller.

//read cookie
var httpCookie = Request.Cookies["panelIdCookie"];

In Order to increase speed of your Marquee text you just need to add like this in your code below:

HTTP is called as a stateless protocol
because each request is executed independently, without any knowledge of the requests that were executed before it, which means once the transaction ends the connection between the browser and the server is also lost.
What makes the protocol stateless
is that in its original design, HTTP is a relatively simple file transfer protocol
:
There was no relationship maintained between one connection and another, even from the same client. This simplifies the contract between client and server, and in many cases minimizes the amount of data that needs to be transferred.
This can be an efficient way of performing different tests on a single statement
select
case colour_txt
when 'red' then 5
when 'green' then 4
when 'orange' then 3
else 0
end as Pass_Flag
this only works on equality comparisons!
Python shouldn't crash when you call getdata(). The image might be corrupted or there is something wrong with your PIL installation. Try it with another image or post the image you are using.
This should break down the image the way you want:
from PIL import Image
im = Image.open('um_000000.png')
pixels = list(im.getdata())
width, height = im.size
pixels = [pixels[i * width:(i + 1) * width] for i in xrange(height)]
put it inside. You can keep processing (if you want) or you can throw a helpful exception that tells the client the value of myString and the index of the array containing the bad value. I think NumberFormatException will already tell you the bad value but the principle is to place all the helpful data in the exceptions that you throw. Think about what would be interesting to you in the debugger at this point in the program.
Consider:
try {
// parse
} catch (NumberFormatException nfe){
throw new RuntimeException("Could not parse as a Float: [" + myString +
"] found at index: " + i, nfe);
}
In the time of need you will really appreciate an exception like this with as much information in it as possible.
There is more than one way to define "memory leak". In particular, there are two primary definitions of "memory leak" that are in common usage among programmers.
The first commonly used definition of "memory leak" is, "Memory was allocated and was not subsequently freed before the program terminated." However, many programmers (rightly) argue that certain types of memory leaks that fit this definition don't actually pose any sort of problem, and therefore should not be considered true "memory leaks".
An arguably stricter (and more useful) definition of "memory leak" is, "Memory was allocated and cannot be subsequently freed because the program no longer has any pointers to the allocated memory block." In other words, you cannot free memory that you no longer have any pointers to. Such memory is therefore a "memory leak". Valgrind uses this stricter definition of the term "memory leak". This is the type of leak which can potentially cause significant heap depletion, especially for long lived processes.
The "still reachable" category within Valgrind's leak report refers to allocations that fit only the first definition of "memory leak". These blocks were not freed, but they could have been freed (if the programmer had wanted to) because the program still was keeping track of pointers to those memory blocks.
In general, there is no need to worry about "still reachable" blocks. They don't pose the sort of problem that true memory leaks can cause. For instance, there is normally no potential for heap exhaustion from "still reachable" blocks. This is because these blocks are usually one-time allocations, references to which are kept throughout the duration of the process's lifetime. While you could go through and ensure that your program frees all allocated memory, there is usually no practical benefit from doing so since the operating system will reclaim all of the process's memory after the process terminates, anyway. Contrast this with true memory leaks which, if left unfixed, could cause a process to run out of memory if left running long enough, or will simply cause a process to consume far more memory than is necessary.
Probably the only time it is useful to ensure that all allocations have matching "frees" is if your leak detection tools cannot tell which blocks are "still reachable" (but Valgrind can do this) or if your operating system doesn't reclaim all of a terminating process's memory (all platforms which Valgrind has been ported to do this).
You're passing the same model to the partial view as is being passed to the main view, and they are different types. The model is a DbSet
of Note
s, where you need to pass in a single Note
.
You can do this by adding a parameter, which I'm guessing as it's the create form would be a new Note
@Html.Partial("_CreateNote", new QuickNotes.Models.Note())
If both your client and service is installed on the same machine, and you are facing this problem with the correct (read: tried and tested elsewhere) client and service configurations, then this might be worth checking.
Check host entries in your host file
%windir%/system32/drivers/etc/hosts
Check to see if you are accessing your web service with a hostname, and that same hostname has been associated with an IP address in the hosts file mentioned above. If yes, NTLM/Windows credentials will NOT be passed from the client to the service as any request for that hostname will be routed again at the machine level.
Try either of the following
Edit: Somehow the above situation is relevant on a load-balanced scenario. However, if removing the host entries is not possible, then disabling loop back check on the machine will help. Refer method 2 in the article https://support.microsoft.com/en-us/kb/896861
There is actual a hack which makes it possible to add multiline placeholders in Webkit browsers, Chrome used to work but in more recent versions they removed it:
First add the first line of your placeholder to the html5 as usual
<textarea id="text1" placeholder="Line 1" rows="10"></textarea>
then add the rest of the line by css:
#text1::-webkit-input-placeholder::after {
display:block;
content:"Line 2\A Line 3";
}
If you want to keep your lines at one place you can try the following. The downside of this is that other browsers than chrome, safari, webkit-etc. don't even show the first line:
<textarea id="text2" placeholder="." rows="10"></textarea>?
then add the rest of the line by css:
#text2::-webkit-input-placeholder{
color:transparent;
}
#text2::-webkit-input-placeholder::before {
color:#666;
content:"Line 1\A Line 2\A Line 3\A";
}
It would be very great, if s.o. could get a similar demo working on Firefox.

What Every Computer Scientist Should Know About Floating-Point Arithmetic
Floating-point numbers cannot represent all the numbers. In particular, 2.51 cannot be represented by a floating-point number, and is represented by a number very close to it:
>>> print "%.16f" % 2.51
2.5099999999999998
>>> 2.51*100
250.99999999999997
>>> 4.02*100
401.99999999999994
If you use int, which truncates the numbers, you get:
250
401
Have a look at the Decimal type.
Every time an entity is updated in the database the version field will be increased by one. Every operation that updates the entity in the database will have appended WHERE version = VERSION_THAT_WAS_LOADED_FROM_DATABASE
to its query.
In checking affected rows of your operation the jpa framework can make sure there was no concurrent modification between loading and persisting your entity because the query would not find your entity in the database when it's version number has been increased between load and persist.
From the page you referenced:
When you raise Http404 from within a view, Django will load a special view devoted to handling 404 errors. It finds it by looking for the variable handler404 in your root URLconf (and only in your root URLconf; setting handler404 anywhere else will have no effect), which is a string in Python dotted syntax – the same format the normal URLconf callbacks use. A 404 view itself has nothing special: It’s just a normal view.
So I believe you need to add something like this to your urls.py:
handler404 = 'views.my_404_view'
and similar for handler500.
I was also having above doubt, what worked for me is
ALTER TABLE `your_table` CHANGE `property` `property`
VARCHAR(whatever_you_want) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL;
There are two ways to handle this.
1) Check the event.target result in your callback to see if it matches your parent div
var g_ParentDiv;
function OnMouseOut(event) {
if (event.target != g_ParentDiv) {
return;
}
// handle mouse event here!
};
window.onload = function() {
g_ParentDiv = document.getElementById("parentdiv");
g_ParentDiv.onmouseout = OnMouseOut;
};
<div id="parentdiv">
<img src="childimage.jpg" id="childimg" />
</div>
2) Or use event capturing and call event.stopPropagation in the callback function
var g_ParentDiv;
function OnMouseOut(event) {
event.stopPropagation(); // don't let the event recurse into children
// handle mouse event here!
};
window.onload = function() {
g_ParentDiv = document.getElementById("parentdiv");
g_ParentDiv.addEventListener("mouseout", OnMouseOut, true); // pass true to enable event capturing so parent gets event callback before children
};
<div id="parentdiv">
<img src="childimage.jpg" id="childimg" />
</div>

It looks like the only way is to provide the whole modal structure with your ajax response.
As you can check from the bootstrap source code, the load function is binded to the root element.
In case you can't modify the ajax response, a simple workaround could be an explicit call of the $(..).modal(..)
plugin on your body element, even though it will probably break the show/hide functions of the root element.
Some of the answers of this post are valid, but using TypeToken, the Gson library generates a Tree objects whit unreal types for your application.
To get it I had to read the array and convert one by one the objects inside the array. Of course this method is not the fastest and I don't recommend to use it if you have the array is too big, but it worked for me.
It is necessary to include the Json library in the project. If you are developing on Android, it is included:
/**
* Convert JSON string to a list of objects
* @param sJson String sJson to be converted
* @param tClass Class
* @return List<T> list of objects generated or null if there was an error
*/
public static <T> List<T> convertFromJsonArray(String sJson, Class<T> tClass){
try{
Gson gson = new Gson();
List<T> listObjects = new ArrayList<>();
//read each object of array with Json library
JSONArray jsonArray = new JSONArray(sJson);
for(int i=0; i<jsonArray.length(); i++){
//get the object
JSONObject jsonObject = jsonArray.getJSONObject(i);
//get string of object from Json library to convert it to real object with Gson library
listObjects.add(gson.fromJson(jsonObject.toString(), tClass));
}
//return list with all generated objects
return listObjects;
}catch(Exception e){
e.printStackTrace();
}
//error: return null
return null;
}
Yes, you can put arrays in sessions, example:
$_SESSION['name_here'] = $your_array;
Now you can use the $_SESSION['name_here']
on any page you want but make sure that you put the session_start()
line before using any session functions, so you code should look something like this:
session_start();
$_SESSION['name_here'] = $your_array;
Possible Example:
session_start();
$_SESSION['name_here'] = $_POST;
Now you can get field values on any page like this:
echo $_SESSION['name_here']['field_name'];
As for the second part of your question, the session variables remain there unless you assign different array data:
$_SESSION['name_here'] = $your_array;
Session life time is set into php.ini file.
You can use css like this:
overflow-y: scroll;
overflow-x: hidden;
Use head
:
dnow <- data.frame(x=rnorm(100), y=runif(100))
head(dnow,4) ## default is 6
As @oportocala mentions, an empty string will not result in the expected empty array.
So to counter, do:
str
.split(',')
.map(entry => entry.trim())
.filter(entry => entry)
For an array of expected integers, do:
str
.split(',')
.map(entry => parseInt(entry))
.filter(entry => typeof entry ==='number')
Use something like Notepad++ (or even Notepad), 'Save As', and enter the name .htaccess that way. I always found it weird, but it lets you do it from a program!
If you want it to be truly dynamic and select the radio that corresponds to the incoming data, this works. It's using the gender value of the data passed in or uses default.
if(data['gender'] == ''){
$('input:radio[name="gender"][value="Male"]').prop('checked', true);
}else{
$('input:radio[name="gender"][value="' + data['gender'] +'"]').prop('checked', true);
};
Can I see (...) the real SQL
If you want to see the SQL sent directly to the database (that is formatted similar to your example), you'll have to use some kind of jdbc driver proxy like P6Spy (or log4jdbc).
Alternatively you can enable logging of the following categories (using a log4j.properties
file here):
log4j.logger.org.hibernate.SQL=DEBUG
log4j.logger.org.hibernate.type=TRACE
The first is equivalent to hibernate.show_sql=true
, the second prints the bound parameters among other things.
//program to form1 to form2
private void button1_Click(object sender, EventArgs e)
{
//MessageBox.Show("Welcome Admin");
Form2 frm = new Form2();
frm.Show();
this.Hide();

In my case I was running under a different user than the one I was expecting.
I had 'DRIVER={SQL Server};SERVER=...;DATABASE=...;Trusted_Connection=false;User Id=XXX;Password=YYY'
as the connection string I passed to pypyodbc.connect()
, but the connection was still using the credentials of the Windows user that ran the script (I verified this using the SQL Server Profiler and by trying an invalid uid/password combination - which didn't result in an expected error).
I decided not to dig into this further, since switching to this better way of connecting fixed the issue:
conn = pypyodbc.connect(driver='{SQL Server}', server='servername', database='dbname', uid='userName', pwd='Password')
As other users have said you should surround your call with a try{...} catch{...}
block. But since Java 1.5 was released, there is TimeUnit class which do the same as Thread.sleep(millis) but is more convenient.
You can pick time unit for sleep operation.
try {
TimeUnit.NANOSECONDS.sleep(100);
TimeUnit.MICROSECONDS.sleep(100);
TimeUnit.MILLISECONDS.sleep(100);
TimeUnit.SECONDS.sleep(100);
TimeUnit.MINUTES.sleep(100);
TimeUnit.HOURS.sleep(100);
TimeUnit.DAYS.sleep(100);
} catch (InterruptedException e) {
//Handle exception
}
Also it has additional methods: TimeUnit Oracle Documentation
