The error indicates that the two tables have the 1 or more column names that have the same column name.
Anyone with the same error who doesn't want to provide a suffix can rename the columns instead. Also make sure the index of both DataFrames match in type and value if you don't want to provide the on='mukey'
setting.
# rename example
df_a = df_a.rename(columns={'a_old': 'a_new', 'a2_old': 'a2_new'})
# set the index
df_a = df_a.set_index(['mukus'])
df_b = df_b.set_index(['mukus'])
df_a.join(df_b)
You can use:
input[type=text]
{
/*Styles*/
}
Define your common style attributes inside this. and for extra style you can add a class then.

I found that the sketch I copied for another project was full of 'wrong case' letters. Onc efixed, it ran smoothly.emphasized text
Since I got here with my problem I will add this answer although it is not exactly relevant to the original question. When you are implementing an interface make sure you do not forget to add the type pointer on your member function declarations. Example:
type AnimalSounder interface {
MakeNoise()
}
type Dog struct {
Name string
mean bool
BarkStrength int
}
func (dog *Dog) MakeNoise() {
//implementation
}
I forgot the *(dog Dog) part, I do not recommend it. Then you get into ugly trouble when calling MakeNoice on an AnimalSounder interface variable of type Dog.
A SELECT INTO
statement creates the table for you. There is no need for the CREATE TABLE
statement before hand.
What is happening is that you create #ivmy_cash_temp1
in your CREATE
statement, then the DB tries to create it for you when you do a SELECT INTO
. This causes an error as it is trying to create a table that you have already created.
Either eliminate the CREATE TABLE
statement or alter your query that fills it to use INSERT INTO SELECT
format.
If you need a unique ID added to your new row then it's best to use SELECT INTO
... since IDENTITY()
only works with this syntax.
You can go from String (hex)
to byte array
to String as UTF-8(?)
. Make sure your hex string does not have leading spaces and stuff.
public static byte[] hexStringToByteArray(String hex) {
int l = hex.length();
byte[] data = new byte[l / 2];
for (int i = 0; i < l; i += 2) {
data[i / 2] = (byte) ((Character.digit(hex.charAt(i), 16) << 4)
+ Character.digit(hex.charAt(i + 1), 16));
}
return data;
}
Usage:
String b = "0xfd00000aa8660b5b010006acdc0100000101000100010000";
byte[] bytes = hexStringToByteArray(b);
String st = new String(bytes, StandardCharsets.UTF_8);
System.out.println(st);
requests
library doesn't support ftp links.
To download a file from FTP server you could:
import urllib
urllib.urlretrieve('ftp://server/path/to/file', 'file')
# if you need to pass credentials:
# urllib.urlretrieve('ftp://username:password@server/path/to/file', 'file')
Or:
import shutil
import urllib2
from contextlib import closing
with closing(urllib2.urlopen('ftp://server/path/to/file')) as r:
with open('file', 'wb') as f:
shutil.copyfileobj(r, f)
Python3:
import shutil
import urllib.request as request
from contextlib import closing
with closing(request.urlopen('ftp://server/path/to/file')) as r:
with open('file', 'wb') as f:
shutil.copyfileobj(r, f)
With the command:
sudo apt-get remove --purge mysql\*
you can delete anything related to packages named mysql. Those commands are only valid on debian / debian-based linux distributions (Ubuntu for example).
You can list all installed mysql packages with the command:
sudo dpkg -l | grep -i mysql
For more cleanup of the package cache, you can use the command:
sudo apt-get clean
Also, remember to use the command:
sudo updatedb
Otherwise the "locate" command will display old data.
To install mysql again, use the following command:
sudo apt-get install libmysqlclient-dev mysql-client
This will install the mysql client, libmysql and its headers files.
To install the mysql server, use the command:
sudo apt-get install mysql-server
The simple answer is that you can't. box-shadow applies to the whole element only. You could use a different approach and use ::before in CSS to insert an 1-pixel high element into header nav and set the box-shadow on that instead.
Although there is nothing wrong with the other solutions presented, you could simplify and greatly escalate your solutions by using python's excellent library pandas.
Pandas is a library for handling data in Python, preferred by many Data Scientists.
Pandas has a simplified CSV interface to read and parse files, that can be used to return a list of dictionaries, each containing a single line of the file. The keys will be the column names, and the values will be the ones in each cell.
In your case:
import pandas
def create_dictionary(filename):
my_data = pandas.DataFrame.from_csv(filename, sep='\t', index_col=False)
# Here you can delete the dataframe columns you don't want!
del my_data['B']
del my_data['D']
# ...
# Now you transform the DataFrame to a list of dictionaries
list_of_dicts = [item for item in my_data.T.to_dict().values()]
return list_of_dicts
# Usage:
x = create_dictionary("myfile.csv")
The m000493
method seems to perform some kind of XOR encryption. This means that the same method can be used for both encrypting and decrypting the text. All you have to do is reverse m0001cd
:
string p0 = Encoding.UTF8.GetString(Convert.FromBase64String("OBFZDT..."));
string result = m000493(p0, "_p0lizei.");
// result == "gaia^unplugged^Ta..."
with return m0001cd(builder3.ToString());
changed to return builder3.ToString();
.
I know this is really old, but I'm posting my solution anyways since google finds this thread.

That is what I do. Two dots means drill back one directory closer to root ".." while one "." should mean start where you are at as if it were root. I was having similar issues but adding that fixed it for me. You can even leave the "." in it when uploading to your host because it should work fine so long as your directory setup is exactly the same.

In our case, the reason was a difference in the .dll versions of to sites in IIS. They are placed under each other in IIS, letting you access the other thru a subdomain. It inherits from the first web.config, and combining that with the next web.config, it failed, having different versions of mvc.dll.

Starting from Python 3.1, you can use importlib :
import importlib
foobar = importlib.import_module("foo-bar")
In the latter case, if obj is null you won't get a NullPointerException but a false.

Linker It combines the multiple object files into a single executable program file.

The "evil" answer did not work for me. Instead, I used what was recommended on the JSHints docs page. If you know the warning that is thrown, you can turn it off for a block of code. For example, I am using some third party code that does not use camel case functions, yet my JSHint rules require it, which led to a warning. To silence it, I wrote:
/*jshint -W106 */
save_state(id);
/*jshint +W106 */
With lodash, this can be done using keyBy:
var arr = [
{ key: 'foo', val: 'bar' },
{ key: 'hello', val: 'world' }
];
var result = _.keyBy(arr, o => o.key);
console.log(result);
// Object {foo: Object, hello: Object}
The div doesn't take up all the available horizontal space when absolutely positioned. Explicitly setting the width to 100% will solve the problem:
HTML
<div id="my-div">I want to be centered</div>?
CSS
#my-div {
position: absolute;
bottom: 15px;
text-align: center;
width: 100%;
}
?
if you are using fix height div than you can use padding-top according your design need. or you can use top:50%. if we are using div than vertical align does not work so we use padding top or position according need.
debug1: identity file /Users/tudouya/.ssh/vm/vm_id_rsa.pub type 1
It appears that you're trying to use the wrong key file. The file with the ".pub" extension contains the public portion of the key. The corresponding file without the ".pub" extension contains the private part of the key. When you run an ssh client to connect to a remote server, you have to provide the private key file to the ssh client.
You probably have a line in the your .ssh/config
file (or /etc/ssh_config
) which looks like this:
IdentityFile .../.ssh/vm/vm_id_rsa.pub
You need to remove the ".pub" extension from the filename:
IdentityFile .../.ssh/vm/vm_id_rsa
I wanted to preserve the index, so I adapted the original answer to this solution:
list_df = df.reset_index().values.tolist()
Now you can paste it somewhere else (e.g. to paste into a Stack Overflow question) and latter recreate it:
pd.Dataframe(list_df, columns=['name1', ...])
pd.set_index(['name1'], inplace=True)

The Java runtime library supports validation. Last time I checked this was the Apache Xerces parser under the covers. You should probably use a javax.xml.validation.Validator.
import javax.xml.XMLConstants;
import javax.xml.transform.Source;
import javax.xml.transform.stream.StreamSource;
import javax.xml.validation.*;
import java.net.URL;
import org.xml.sax.SAXException;
//import java.io.File; // if you use File
import java.io.IOException;
...
URL schemaFile = new URL("http://host:port/filename.xsd");
// webapp example xsd:
// URL schemaFile = new URL("http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd");
// local file example:
// File schemaFile = new File("/location/to/localfile.xsd"); // etc.
Source xmlFile = new StreamSource(new File("web.xml"));
SchemaFactory schemaFactory = SchemaFactory
.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
try {
Schema schema = schemaFactory.newSchema(schemaFile);
Validator validator = schema.newValidator();
validator.validate(xmlFile);
System.out.println(xmlFile.getSystemId() + " is valid");
} catch (SAXException e) {
System.out.println(xmlFile.getSystemId() + " is NOT valid reason:" + e);
} catch (IOException e) {}
The schema factory constant is the string http://www.w3.org/2001/XMLSchema
which defines XSDs. The above code validates a WAR deployment descriptor against the URL http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd
but you could just as easily validate against a local file.
You should not use the DOMParser to validate a document (unless your goal is to create a document object model anyway). This will start creating DOM objects as it parses the document - wasteful if you aren't going to use them.
In Vim:
shift-V
(enter visual mode), up down highlight lines in block:s/^/#/
the command will look like this:
:'<,'>s/^/#
hit enter
e.g.
shift-V
jjj
:s/^/#
<enter>
It is indeed possible with the following code
<div href="#" id='a'>
Hover me
</div>
<div id='b'>
Show me
</div>
and css
#a {
display: block;
}
#a:hover + #b {
display:block;
}
#b {
display:none;
}
Now by hovering on element #a shows element #b.

The answers already provided display how much the solution depends on your particular environment. I initially tried upgrading a Windows 8.1 machine; when that failed I tried upgrading a Vista PC. When that failed, I tried Android Studio on the Win 8.1. The problems that we all are encountering are resulting in different solutions because of version conflicts between O/S, Eclipse, Java and, of course, the Google debacle.
Here's what I did: I gave up on the bundle. For Vista I installed Eclipse 4.3.2 (Kepler) and downloaded the SDK installer which loaded 23.0.2. Already had jdk1.6 installed. Only gotcha left was to use the SDK manager to download my minimum platform (API 8) - V20 isn't that far backward compatible. But at least now I am not totally dead in the water.
For Windows 8.1 Android Studio seemed to install. But when I tried to install my Project, it stopped when it complained that google-play-services_lib was not included. I had not been using it, so it appears this is a requirement of Android Studio. Really?
So I went back to Eclipse. I had installed Luna and jdk8u5 but then tried to revert to what worked for Vista. jdk1.6 is not available from Oracle so I had to download 1.7 and hope. Downloaded the SDK which again got 23.0.2. So far so good.
Problem then was installer-r23.0.2-windows apparently is hardwired to find JDK at 'C:\Windows\system32\java.exe':[2]. I set the PATH to jdk1.7.0_65\bin and set JAVA_HOME environment variable to it also. Neither worked. Installer still choked on java8 in Windows\System32.
So I renamed C:\Windows\System32\java.exe to disable it and the installer-r23 found C:\Program Files\Java\jre8\bin\java.exe. The installer completed successfully. Why it didn't like the same file (V8.0.5.13) in Windows\System 32 is a mystery to me but maybe a clue to someone.
Still had to download API 8, but I thought I was operational on the 8.1 machine too.
Except for getting Eclipse to recognize my Motorola RazrM as a USB-attached device. That required going to the Win8.1 DeviceManager and updating the Mot Composite ADB Interface in ADB Interface. That required a download of the Motorola Device Manager. Still the phone did not appear in the Eclipse Devices View. It was waiting for a new confirmation on the phone that apparently has been added to the latest ADT. While I needed to upgrade the driver on my Samsung 10.1 tablet, it had not added the connection request confirmation.
Finally, the nightmares were over. My biggest problem appears to have been leaping to the latest versions - and then trying to regress when 23.0 broke. I think I learned a hard lesson. But, really, does it have to be this hard???
Hope this helps.
This jQuery code catches immediate changes to any element, and should work across all browsers:
$('.myElements').each(function() {
var elem = $(this);
// Save current value of element
elem.data('oldVal', elem.val());
// Look for changes in the value
elem.bind("propertychange change click keyup input paste", function(event){
// If value has changed...
if (elem.data('oldVal') != elem.val()) {
// Updated stored value
elem.data('oldVal', elem.val());
// Do action
....
}
});
});
Use slices instead of arrays for reading. For example, io.Reader
accepts a slice, not an array.
Use slicing instead of zero padding.
Example:
buf := make([]byte, 100)
n, err := myReader.Read(buf)
if n == 0 && err != nil {
log.Fatal(err)
}
consume(buf[:n]) // consume() will see an exact (not padded) slice of read data
Your "bad" output is UTF-8 displayed as CP1252.
On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:
df.to_csv('file.csv',encoding='utf-8-sig')
That encoder will add the BOM.
I made this in my code to do that
note: I am a beginner.

There is a new index method called difference
. It returns the original columns, with the columns passed as argument removed.
Here, the result is used to remove columns B
and D
from df
:
df2 = df[df.columns.difference(['B', 'D'])]
Note that it's a set-based method, so duplicate column names will cause issues, and the column order may be changed.
Advantage over drop
: you don't create a copy of the entire dataframe when you only need the list of columns. For instance, in order to drop duplicates on a subset of columns:
# may create a copy of the dataframe
subset = df.drop(['B', 'D'], axis=1).columns
# does not create a copy the dataframe
subset = df.columns.difference(['B', 'D'])
df = df.drop_duplicates(subset=subset)
You have to set to element_blank()
in theme()
elements you need to remove
ggplot(data = diamonds, mapping = aes(x = clarity)) + geom_bar(aes(fill = cut))+
theme(axis.title.x=element_blank(),
axis.text.x=element_blank(),
axis.ticks.x=element_blank())
You can use the StringUtils class from Apache Commons Lang like this:
StringUtils.stripStart(yourString,"0");
Here's a simpler method to add multiple classes via classList
(supported by all modern browsers, as noted in other answers here):
div.classList.add('foo', 'bar'); // add multiple classes
From: https://developer.mozilla.org/en-US/docs/Web/API/Element/classList#Examples
If you have an array of class names to add to an element, you can use the ES6 spread operator to pass them all into classList.add()
via this one-liner:
let classesToAdd = [ 'foo', 'bar', 'baz' ];
div.classList.add(...classesToAdd);
Note that not all browsers support ES6 natively yet, so as with any other ES6 answer you'll probably want to use a transpiler like Babel, or just stick with ES5 and use a solution like @LayZee's above.
Here's a code snippet showing how to insert a GUID using a parameterised query:
using(SqlConnection conn = new SqlConnection(connectionString))
{
conn.Open();
using(SqlTransaction trans = conn.BeginTransaction())
using (SqlCommand cmd = conn.CreateCommand())
{
cmd.Transaction = trans;
cmd.CommandText = @"INSERT INTO [MYTABLE] ([GuidValue]) VALUE @guidValue;";
cmd.Parameters.AddWithValue("@guidValue", Guid.NewGuid());
cmd.ExecuteNonQuery();
trans.Commit();
}
}
The shortest way without declaring the variable is with Type Hints :
s$ = 123 ' s = "123"
i% = "123" ' i = 123
This will not compile with Option Explicit
. The types will not be Variant
but String
and Integer
You can use Id of the field as well
$('#checkbox1').change(function() {
if($(this).is(":checked")) {
//'checked' event code
return;
}
//'unchecked' event code
});
Do it like this
if (typeof $(this).attr("checked") == "undefined" )
// To check if checkbox is checked
if( $(this).attr("checked")=="checked")
You could try something like this:
[a-zA-Z]{2}[0-9]{6}
Here is a break down of the expression:
[a-zA-Z] # Match a single character present in the list below
# A character in the range between “a” and “z”
# A character in the range between “A” and “Z”
{2} # Exactly 2 times
[0-9] # Match a single character in the range between “0” and “9”
{6} # Exactly 6 times
This will match anywhere in a subject. If you need boundaries around the subject then you could do either of the following:
^[a-zA-Z]{2}[0-9]{6}$
Which ensures that the whole subject matches. I.e there is nothing before or after the subject.
or
\b[a-zA-Z]{2}[0-9]{6}\b
which ensures there is a word boundary on each side of the subject.
As pointed out by @Phrogz, you could make the expression more terse by replacing the [0-9]
for a \d
as in some of the other answers.
[a-zA-Z]{2}\d{6}
int a[20];
int length;
length = sizeof(a) / sizeof(int);
and you can use another way to make your code not be hard-coded to int
Say if you have an array array
you just need to:
int len = sizeof(array) / sizeof(array[0]);
Since Python is a strongly typed language, concatenating a string and an integer as you may do in Perl makes no sense, because there's no defined way to "add" strings and numbers to each other.
Explicit is better than implicit.
...says "The Zen of Python", so you have to concatenate two string objects. You can do this by creating a string from the integer using the built-in str()
function:
>>> "abc" + str(9)
'abc9'
Alternatively use Python's string formatting operations:
>>> 'abc%d' % 9
'abc9'
Perhaps better still, use str.format()
:
>>> 'abc{0}'.format(9)
'abc9'
The Zen also says:
There should be one-- and preferably only one --obvious way to do it.
Which is why I've given three options. It goes on to say...
Although that way may not be obvious at first unless you're Dutch.
Adding manifest.file=manifest.mf into project.properties and creating manifest.mf file in the project directory works fine in NB 6.9 and should work also in NB 6.8.

vector<string> v;

for(string::const_iterator i; i = str.begin(); i <= str.end(); ++i) {
if(*i != delim && i != str.end()) {
tmp += *i;
} else {
v.push_back(tmp);
tmp = "";
}
}
return v;
}
Try these functions,
var JsonToArray = function(json)
{
var str = JSON.stringify(json, null, 0);
var ret = new Uint8Array(str.length);
for (var i = 0; i < str.length; i++) {
ret[i] = str.charCodeAt(i);
}
return ret
};
var binArrayToJson = function(binArray)
{
var str = "";
for (var i = 0; i < binArray.length; i++) {
str += String.fromCharCode(parseInt(binArray[i]));
}
return JSON.parse(str)
}

For anyone that simply are looking to bypass the ERROR page to display the content on shared hosting. You might wanna try and use redirect in .htaccess file. If it is say 406 error, on UnoEuro it didn't seem to work simply deactivating the security. So I used this instead:
ErrorDocument 406 /
Then you can always change the error status using PHP. But be aware that in my case doing so means I am opening a door to SQL injections as I am bypassing WAF. So you will need to make sure that you either have your own security measures or enable the security again asap.

Create a helpers.php
file in your app folder and load it up with composer:
"autoload": {
"classmap": [
...
],
"psr-4": {
"App\\": "app/"
},
"files": [
"app/helpers.php" // <---- ADD THIS
]
},
After adding that to your composer.json
file, run the following command:
composer dump-autoload
If you don't like keeping your helpers.php
file in your app
directory (because it's not a PSR-4 namespaced class file), you can do what the laravel.com
website does: store the helpers.php
in the bootstrap directory. Remember to set it in your composer.json
file:
"files": [
"bootstrap/helpers.php"
]
Tip:
If you want to use the different file name instead of helpers
, you can change the file name and path.
Also, you can create multiple helper files.
It will look like this:
"autoload": {
"classmap": [

-H "text/xml"
isn't a valid header. You need to provide the full header:
-H "Content-Type: text/xml"
You can write the where
clause as:
where (case when (:stateCode = '') then (1)
when (:stateCode != '') and (vw.state_cd in (:stateCode)) then 1
else 0)
end) = 1;
Alternatively, remove the case
entirely:
where (:stateCode = '') or
((:stateCode != '') and vw.state_cd in (:stateCode));
Or, even better:
where (:stateCode = '') or vw.state_cd in (:stateCode)
Just as Matt says, use Process.Start.
You can pass a URL, or a document. They will be started by the registered application.
Example:
Process.Start("Test.Txt");
This will start Notepad.exe with Text.Txt loaded.
[Edit]: Please ignore, not available in php now.
There is one more which you can use
<?php
$fields = array(
'name' => 'mike',
'pass' => 'se_ret'
);
$files = array(
array(
'name' => 'uimg',
'type' => 'image/jpeg',
'file' => './profile.jpg',
)
);
$response = http_post_fields("http://www.example.com/", $fields, $files);
?>
You can use a <div>
to cover the scrollbar if you really want it to disappear.
Although it won't work on IE6, modern browsers do let you put a <div>
on top of it.
I imagine that trygetvalue is doing something more like:
if(myDict.ReallyOptimisedVersionofContains(someKey))
{
someVal = myDict[someKey];
return true;
}
return false;
So hopefully no try/catch anywhere.
I think it is just a method of convenience really. I generally use it as it saves a line of code or two.
To call a specific exception such as FileNotFoundException use this format
if (-not (Test-Path $file))
{
throw [System.IO.FileNotFoundException] "$file not found."
}
To throw a general exception use the throw command followed by a string.
throw "Error trying to do a task"
When used inside a catch, you can provide additional information about what triggered the error
You can also try
System.Environment.GetEnvironmentVariable("UserName");
Raymond Chen has a really excellent blog post on this:
Try javax.net.ssl.keyStorePassword
instead of javax.net.ssl.keyPassword
: the latter isn't mentioned in the JSSE ref guide.
The algorithms you mention should be there by default using the default security providers. NoSuchAlgorithmException
s are often cause by other underlying exceptions (file not found, wrong password, wrong keystore type, ...). It's useful to look at the full stack trace.
You could also use -Djavax.net.debug=ssl
, or at least -Djavax.net.debug=ssl,keymanager
, to get more debugging information, if the information in the stack trace isn't sufficient.
Definitely EditPad Lite !
It's extremely fast not just while opening files, but also functions like "Replace All", trimming of leading/trailing whitespaces or converting content to lowercase are very fast.
And it is also very similar to Notepad++ ;)
Here's a list splitting routine I wrote a couple months ago:
public static List<List<T>> Chunk<T>(
List<T> theList,
int chunkSize
)
{
List<List<T>> result = theList
.Select((x, i) => new {
data = x,
indexgroup = i / chunkSize
})
.GroupBy(x => x.indexgroup, x => x.data)
.Select(g => new List<T>(g))
.ToList();
return result;
}
You can try this one it is short :)
SystemClock.sleep(7000);
It will sleep for 7 sec look at documentation
Below is answering the original first question:
Should I use
dict
orOrderedDict
in Python 3.6?
I think this sentence from the documentation is actually enough to answer your question
The order-preserving aspect of this new implementation is considered an implementation detail and should not be relied upon
dict
is not explicitly meant to be an ordered collection, so if you want to stay consistent and not rely on a side effect of the new implementation you should stick with OrderedDict
.
Make your code future proof :)
There's a debate about that here.
EDIT: Python 3.7 will keep this as a feature see
I agree with @Bloomca. Passing the value needed from the store into the dispatch function as an argument seems simpler than exporting the store. I made an example here:
import React from "react";
import {connect} from "react-redux";
import * as actions from '../actions';
class App extends React.Component {
handleClick(){
const data = this.props.someStateObject.data;
this.props.someDispatchFunction(data);
}
render(){
return (
<div>
<div onClick={ this.handleClick.bind(this)}>Click Me!</div>
</div>
);
}
}
const mapStateToProps = (state) => {
return { someStateObject: state.someStateObject };
};
const mapDispatchToProps = (dispatch) => {
return {
someDispatchFunction:(data) => { dispatch(actions.someDispatchFunction(data))},
};
}
export default connect(mapStateToProps, mapDispatchToProps)(App);
It doesn't seem anyone has addressed how to specify URLs with embedded parameters. Any URL that contains parameters it won't possible to specify the specific URL in LSApplicationsQueriesSchemes. For example, assume I have an email app that passes the the senders email address:
myemail://[email protected]
The only way it seems to get it to work in iOS9 is to remove any parameters.
(In the diagrams and text below, PC
is the address of the branch instruction itself. PC+4
is the end of the branch instruction itself, and the start of the branch delay slot. Except in the absolute jump diagram.)
In MIPS branch instruction has only 16 bits offset to determine next instruction. We need a register added to this 16 bit value to determine next instruction and this register is actually implied by architecture. It is PC register since PC gets updated (PC+4) during the fetch cycle so that it holds the address of the next instruction.
We also limit the branch distance to -2^15 to +2^15 - 1
instruction from the (instruction after the) branch instruction. However, this is not real issue since most branches are local anyway.
So step by step :
For Jump instruction MIPS has only 26 bits to determine Jump location. Jumps are relative to PC in MIPS. Like branch, immediate jump value needs to be word-aligned; therefore, we need to multiply 26 bit address with four.
Again step by step:
In other words, replace the lower 28 bits of the PC + 4 with the lower 26 bits of the fetched instruction shifted left by 2 bits.
Jumps are region-relative to the branch-delay slot, not necessarily the branch itself. In the diagram above, PC has already advanced to the branch delay slot before the jump calculation. (In a classic-RISC 5 stage pipeline, the BD was fetched in the same cycle the jump is decoded, so that PC+4 next instruction address is already available for jumps as well as branches, and calculating relative to the jump's own address would have required extra work to save that address.)

One way to do it would be:
//
and before the Code text. Notice the vertical blue line in the below image( that will appear once the selection is made, then you can insert any number of characters in between them)
I couldn't find a direct way to do that. The interesting thing is that it is mentioned in the C# Coding Conventions (C# Programming Guide) under Commenting Conventions.
Insert one space between the comment delimiter (//) and the comment text
But the default implementation of commenting in visual studio doesn't insert any space
You're in luck, I use the exact thing in my CMS
When you want to store the order, just call the JavaScript method saveOrder()
. It will make an AJAX POST
request to saveorder.php, but of course you could always post it as a regular form.
<script type="text/javascript">
function saveOrder() {
var articleorder="";
$("#sortable li").each(function(i) {
if (articleorder=='')
articleorder = $(this).attr('data-article-id');
else
articleorder += "," + $(this).attr('data-article-id');
});
//articleorder now contains a comma separated list of the ID's of the articles in the correct order.
$.post('/saveorder.php', { order: articleorder })
.success(function(data) {
alert('saved');
})
.error(function(data) {
alert('Error: ' + data);
});
}
</script>
<ul id="sortable">
<?php
//my way to get all the articles, but you should of course use your own method.
$articles = Page::Articles();
foreach($articles as $article) {
?>
<li data-article-id='<?=$article->Id()?>'><?=$article->Title()?></li>
<?
}
?>
</ul>
<input type='button' value='Save order' onclick='saveOrder();'/>
In saveorder.php; Keep in mind I removed all verification and checking.
<?php
$orderlist = explode(',', $_POST['order']);
foreach ($orderlist as $k=>$order) {
echo 'Id for position ' . $k . ' = ' . $order . '<br>';
}
?>
Why not just make the server return the names?
["Woodland Hills", "none", "Los Angeles", "Laguna Hills"]
Then create the <option>
elements using JavaScript.
$.ajax({
url:'suggest.html',
type:'POST',
data: 'q=' + str,
dataType: 'json',
success: function( json ) {
$.each(json, function(i, value) {
$('#myselect').append($('<option>').text(value).attr('value', value));
});
}
});
aList=[1,2,3]
i=0
for item in aList:
if i<2:
aList.remove(item)
i+=1
aList
[2]
The moral is when modifying a list in a loop driven by the list, takes two steps:
aList=[1,2,3]
i=0
for item in aList:
if i<2:
aList[i]="del"
i+=1
aList
['del', 'del', 3]
for i in range(2):
del aList[0]
aList
[3]
You can also do it with pure python without using any modules.
# format as a block of csv text to do whatever you want
csv_rows = ["{},{}".format(i, j) for i, j in array]
csv_text = "\n".join(csv_rows)
# write it to a file
with open('file.csv', 'w') as f:
f.write(csv_text)
Step 1: Click on Create new File
Step 2: Enter the folder name that you want, then press /
Step 3: Enter a sample file name. You must enter some text.
Step 4: Click Commit new file to create the folder
Step 5: Your folder is created!
Filezilla just released a Pro version of their FTP client. It connects to S3 buckets in a streamlined FTP like experience. I use it myself (no affiliation whatsoever) and it works great.
If they are two integers you can try a quick and dirty trick: Map<String, ?>
using the key as i+"#"+j
.
If the key i+"#"+j
is the same as j+"#"+i
try min(i,j)+"#"+max(i,j)
.
If a class is declared as static then the variables and methods need to be declared as static.
A class can be declared static, indicating that it contains only static members. It is not possible to create instances of a static class using the new keyword. Static classes are loaded automatically by the .NET Framework common language runtime (CLR) when the program or namespace containing the class is loaded.
Use a static class to contain methods that are not associated with a particular object. For example, it is a common requirement to create a set of methods that do not act on instance data and are not associated to a specific object in your code. You could use a static class to hold those methods.
->The main features of a static class are:
Example
static class CollegeRegistration
{
//All static member variables
static int nCollegeId; //College Id will be same for all the students studying
static string sCollegeName; //Name will be same
static string sColegeAddress; //Address of the college will also same
//Member functions
public static int GetCollegeId()
{
nCollegeId = 100;
return (nCollegeID);
}
//similarly implementation of others also.
} //class end
public class student
{
int nRollNo;
string sName;
public GetRollNo()
{
nRollNo += 1;
return (nRollNo);
}
//similarly ....
public static void Main()
{
//Not required.
//CollegeRegistration objCollReg= new CollegeRegistration();
//<ClassName>.<MethodName>
int cid= CollegeRegistration.GetCollegeId();
string sname= CollegeRegistration.GetCollegeName();
} //Main end
}
There are a number of ways of achieving your result. If you're just wanting a solution for your case, use string multiplication as @Ant mentions. This is only going to work if each of your print
statements prints the same string. Note that it works for multiplication of any length string (e.g. 'foo' * 20
works).
>>> print 'a' * 20
aaaaaaaaaaaaaaaaaaaa
If you want to do this in general, build up a string and then print it once. This will consume a bit of memory for the string, but only make a single call to print
. Note that string concatenation using +=
is now linear in the size of the string you're concatenating so this will be fast.
>>> for i in xrange(20):
... s += 'a'
...
>>> print s
aaaaaaaaaaaaaaaaaaaa
Or you can do it more directly using sys.stdout.write(), which print
is a wrapper around. This will write only the raw string you give it, without any formatting. Note that no newline is printed even at the end of the 20 a
s.
>>> import sys
>>> for i in xrange(20):
... sys.stdout.write('a')
...
aaaaaaaaaaaaaaaaaaaa>>>
Python 3 changes the print
statement into a print() function, which allows you to set an end
parameter. You can use it in >=2.6 by importing from __future__
. I'd avoid this in any serious 2.x code though, as it will be a little confusing for those who have never used 3.x. However, it should give you a taste of some of the goodness 3.x brings.
>>> from __future__ import print_function
>>> for i in xrange(20):
... print('a', end='')
...
aaaaaaaaaaaaaaaaaaaa>>>
It's because you have included a leading /
in your file path. The /
makes it start at the top of your filesystem. Note: filesystem path, not Web site path (you're not accessing it over HTTP). You can use a relative path with include_once
(one that doesn't start with a leading /
).
You can change it to this:
include_once 'headerSite.php';
That will look first in the same directory as the file that's including it (i.e. C:\xampp\htdocs\PoliticalForum\
in your example.
You can use SELECT * FROM INFORMATION_SCHEMA.COLUMNS
but I suspect you created the destination database from a script of the source database so it is very likely that they columns will be the same.
Some comparisons might bring something up though.
These sorts of errors sometimes come from trying to insert too much data into varchar columns too.
You'd need attach an onFocus
event to the input field via Javascript:
<input type="text" onfocus="this.value=''" value="..." ... />

Splash screens just waste your time, right? As an Android developer, when I see a splash screen, I know that some poor dev had to add a three-second delay to the code.
Then, I have to stare at some picture for three seconds until I can use the app. And I have to do this every time it’s launched. I know which app I opened. I know what it does. Just let me use it!
Splash Screens the Right Way
I believe that Google isn’t contradicting itself; the old advice and the new stand together. (That said, it’s still not a good idea to use a splash screen that wastes a user’s time. Please don’t do that.)
However, Android apps do take some amount of time to start up, especially on a cold start. There is a delay there that you may not be able to avoid. Instead of leaving a blank screen during this time, why not show the user something nice? This is the approach Google is advocating. Don’t waste the user’s time, but don’t show them a blank, unconfigured section of the app the first time they launch it, either.
If you look at recent updates to Google apps, you’ll see appropriate uses of the splash screen. Take a look at the YouTube app, for example.
Yes, this is a current issue in Chrome. There is an issue report here.
The fix will appear in 40.x.y.z versions.
Until then? I don't think you can resolve the issue yourself. But you can ignore it. The shown error is only related to the dev tools and does not influence the behavior of your website. If you have any other problems they are not related to this error.
Important to note with elementFormDefault is that it applies to locally defined elements, typically named elements inside a complexType block, as opposed to global elements defined on the top-level of the schema. With elementFormDefault="qualified" you can address local elements in the schema from within the xml document using the schema's target namespace as the document's default namespace.
In practice, use elementFormDefault="qualified" to be able to declare elements in nested blocks, otherwise you'll have to declare all elements on the top level and refer to them in the schema in nested elements using the ref attribute, resulting in a much less compact schema.
This bit in the XML Schema Primer talks about it: http://www.w3.org/TR/xmlschema-0/#NS
Assuming t1 is the folder with files in it, and t2 is the empty directory. What you want is something like this:
sudo cp -R t1/* t2/
Bear in mind, for the first example, t1 and t2 have to be the full paths, or relative paths (based on where you are). If you want, you can navigate to the empty folder (t2) and do this:
sudo cp -R t1/* ./
Or you can navigate to the folder with files (t1) and do this:
sudo cp -R ./* t2/
Note: The * sign (or wildcard) stands for all files and folders. The -R flag means recursively (everything inside everything).
Assuming you mean "client side JavaScript" - then you can't, at least not directly.
The session data is stored on the server, so client side code can't see it without communicating with the server.
To access it you must make an HTTP request and have a server side program modify / read & return the data.
final ListView lv = (ListView) findViewById(R.id.ListView01);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) {
String selectedFromList =(String) (lv.getItemAtPosition(myItemInt));
}
});
I hope this fixes your problem.
If you're needing something simple, would this fit the bill?
Map<K, V> myCache = Collections.synchronizedMap(new WeakHashMap<K, V>());
It wont save to disk, but you said you wanted simple...
Links:
(As Adam commented, synchronising a map has a performance hit. Not saying the idea doesn't have hairs on it, but would suffice as a quick and dirty solution.)
For the record, my system is Ubuntu Server 20.04 and none of the solutions here worked. For me, I installed PHP 7.4 and I had to edit enter code here
/etc/php/7.4/apache2/php.ini`.
Within this, search for ;extension=mysqli
, uncomment and change mysqli
to mysqlnd
so it should look like this extension=mysqlnd
. I tried using mysqli
but I faced the same error as if I didn't enable it but mysqlnd
worked for me.
A very important distinction, which is easy to miss, is the default bheavior of these two functions, when it comes to exceptions.
I'll use this example to simulate a coroutine that will raise exceptions, sometimes -
import asyncio
import random
async def a_flaky_tsk(i):
await asyncio.sleep(i) # bit of fuzz to simulate a real-world example
if i % 2 == 0:
print(i, "ok")
else:
print(i, "crashed!")
raise ValueError
coros = [a_flaky_tsk(i) for i in range(10)]
await asyncio.gather(*coros)
outputs -
0 ok
1 crashed!

As you can see, the coros after index 1
never got to execute.
But await asyncio.wait(coros)
continues to execute tasks, even if some of them fail -

Ofcourse, this behavior can be changed for both by using -
asyncio.gather(..., return_exceptions=True)
or,
asyncio.wait([...], return_when=asyncio.FIRST_EXCEPTION)
But it doesn't end here!
Notice:
Task exception was never retrieved
in the logs above.
asyncio.wait()
won't re-raise exceptions from the child tasks until you await
them individually. (The stacktrace in the logs are just messages, they cannot be caught!)
done, pending = await asyncio.wait(coros)
for tsk in done:
try:
await tsk
except Exception as e:
print("I caught:", repr(e))
Output -
0 ok
1 crashed!
2 ok
3 crashed!
4 ok
5 crashed!
6 ok
7 crashed!
8 ok
9 crashed!
I caught: ValueError()
I caught: ValueError()
I caught: ValueError()
I caught: ValueError()
I caught: ValueError()
On the other hand, to catch exceptions with asyncio.gather()
, you must -
results = await asyncio.gather(*coros, return_exceptions=True)
for result_or_exc in results:
if isinstance(result_or_exc, Exception):
print("I caught:", repr(result_or_exc))
(Same output as before)
In many workflows where you want to attach a default / initial value for arbitrary keys, you don't need to hash each key individually ahead of time. You can use collections.defaultdict
. For example:
from collections import defaultdict
d = defaultdict(lambda: None)
print(d[1]) # None
print(d[2]) # None
print(d[3]) # None
This is more efficient, it saves having to hash all your keys at instantiation. Moreover, defaultdict
is a subclass of dict
, so there's usually no need to convert back to a regular dictionary.
For workflows where you require controls on permissible keys, you can use dict.fromkeys
as per the accepted answer:
d = dict.fromkeys([1, 2, 3, 4])
If you are manually making your entity's CoreDataClass and CoreDataProperties, make sure you go to your xcdatamodel and set the Codegen in the inspector tab to "Manual/None". Xcode will automatically create a duplicate class for you if this is set as "Class Definition".
This is how I do it:
with open(txtfile, 'r') as infile, open(csvfile, 'w') as outfile:
stripped = (line.strip() for line in infile)
lines = (line.split(",") for line in stripped if line)
writer = csv.writer(outfile)
writer.writerows(lines)
Hope it helps!

The standard definiton allows only for adding or deleting a single class. A couple of small wrapper functions can do what you ask :
function addClasses (el, classes) {
classes = Array.prototype.slice.call (arguments, 1);
console.log (classes);
for (var i = classes.length; i--;) {
classes[i] = classes[i].trim ().split (/\s*,\s*|\s+/);
for (var j = classes[i].length; j--;)
el.classList.add (classes[i][j]);
}
}
function removeClasses (el, classes) {
classes = Array.prototype.slice.call (arguments, 1);
for (var i = classes.length; i--;) {
classes[i] = classes[i].trim ().split (/\s*,\s*|\s+/);
for (var j = classes[i].length; j--;)
el.classList.remove (classes[i][j]);
}
}
These wrappers allow you to specify the list of classes as separate arguments, as strings with space or comma separated items, or a combination. For an example see http://jsfiddle.net/jstoolsmith/eCqy7

To test a code that depends on the System.DateTime
, the system.dll
must be mocked.
There are two framework that I know of that does this. Microsoft fakes and Smocks.
Microsoft fakes require visual studio 2012 ultimatum and works straight out of the compton.
Smocks is an open source and very easy to use. It can be downloaded using NuGet.
The following shows a mock of System.DateTime
:
Smock.Run(context =>
{
context.Setup(() => DateTime.Now).Returns(new DateTime(2000, 1, 1));
// Outputs "2000"
Console.WriteLine(DateTime.Now.Year);
});
look, i had the same problem but i insert the function as a global variable
as
var RNumber = Int(arc4random_uniform(9)+1)
func GetCase(){
your code
}
obviously this is not efficent, so then i just copy and paste the code into the function so it could be reusable, then xcode suggest me to set the var as constant so my code were
func GetCase() {
let RNumber = Int(arc4random_uniform(9)+1)
if categoria == 1 {

well thats a part of my code so xcode tell me something of inmutable and initialization but, it build the app anyway and that advice simply dissapear
hope it helps
I think this is what you want:
/grand/parent/child[@id="#grand"]
fname = "feed.txt"
feed = open(fname, 'r')
num_lines = len(feed.splitlines())
num_words = 0
num_chars = 0
for line in lines:
num_words += len(line.split())
Give your log a name. I called mine "wawa".
In Android Studio, go to Android-> Edit Filter Configurations
Then type in the name you gave the logs. In my case, it's called "wawa". Here are some examples of the types of filters you can do. You can filter by System.out, System.err, Logs, or package names:
If you are using 5.6 php,
sudo apt-get install php5.6-curl
You can do it by RENAME statement for each table in your "current_db" after create the new schema "other_db"
RENAME TABLE current_db.tbl_name TO other_db.tbl_name
Source Rename Table Syntax
Something like this should do it for you.
Sub CombineColumns1()
Dim xRng As Range
Dim i As Long, j As Integer
Dim xNextRow As Long
Dim xTxt As String
On Error Resume Next
With ActiveSheet
xTxt = .RangeSelection.Address
Set xRng = Application.InputBox("please select the data range", "Kutools for Excel", xTxt, , , , , 8)
If xRng Is Nothing Then Exit Sub
j = xRng.Columns(1).Column
For i = 4 To xRng.Columns.Count Step 3
'Need to recalculate the last row, as some of the final columns may not have data in all rows
xNextRow = .Cells(.Rows.Count, j).End(xlUp).Row + 1
.Range(xRng.Cells(1, i), xRng.Cells(xRng.Rows.Count, i + 2)).Copy .Cells(xNextRow, j)
.Range(xRng.Cells(1, i), xRng.Cells(xRng.Rows.Count, i + 2)).Clear
Next
End With
End Sub
You could do this too.
Sub TransposeFormulas()
Dim vFormulas As Variant
Dim oSel As Range
If TypeName(Selection) <> "Range" Then
MsgBox "Please select a range of cells first.", _
vbOKOnly + vbInformation, "Transpose formulas"
Exit Sub
End If
Set oSel = Selection
vFormulas = oSel.Formula
vFormulas = Application.WorksheetFunction.Transpose(vFormulas)
oSel.Offset(oSel.Rows.Count + 2).Resize(oSel.Columns.Count, oSel.Rows.Count).Formula = vFormulas
End Sub

Regarding the width of your website, you'll want to consider using a wrapper class to surround your content (this should help to constrain your element widths and prevent them from expanding too far beyond the content):
<style>
.wrapper {
width: 980px;
}
</style>
<body>
<div class="wrapper">
//everything else
</div>
</body>
As far as the content boxes go, I would suggest trying to use
<style>
.boxes {
display: inline-block;
width: 360px;
height: 360px;
}
#leftBox {
float: left;
}
#rightBox {
float: right;
}
</style>
I would spend some time researching the box-object model and all of the "display" properties. They will be forever helpful. Pay particularly close attention to "inline-block", I use it practically every day.
lets say you have this:
<ul>
<li></li>
<li>
<ul>
<li></li>
<li></li>
</ul>
</li>
<li></li>
<ul>
Now if you DONT need IE6 compatibility (reference at Quirksmode) you can have the following css
ul li { background:#fff; }
ul>li { background:#f0f; }
The >
is a direct children operator, so in this case only the first level of li
s will be purple.
Hope this helps
Just download composer and install phpMailler autoloader.php
https://github.com/PHPMailer/PHPMailer/blob/master/composer.json
once composer is loaded use below code:
require_once("phpMailer/class.phpmailer.php");
require_once("phpMailer/PHPMailerAutoload.php");
$mail = new PHPMailer(true);
$mail->SMTPDebug = true;
$mail->SMTPSecure = "tls";
$mail->SMTPAuth = true;
$mail->Username = 'youremail id';
$mail->Password = 'youremail password';
$mail_from = "youremail id";
$subject = "Your Subject";
$body = "email body";
$mail_to = "receiver_email";
$mail->IsSMTP();
try {
$mail->Host= "smtp.your.com";
$mail->Port = "Your SMTP Port No";// ssl port :465,
$mail->Debugoutput = 'html';
$mail->AddAddress($mail_to, "receiver_name");
$mail->SetFrom($mail_from,'AmpleChat Team');
$mail->Subject = $subject;
$mail->MsgHTML($body);
$mail->Send();
$emailreturn = 200;
} catch (phpmailerException $e) {
$emailreturn = $e->errorMessage();
} catch (Exception $e) {
$emailreturn = $e->getMessage();
}
echo $emailreturn;
Hope this will work.
I'm not 100% sure on this, but I think that adding a view to the view hierarchy directly means calling -addSubview:
on the view controller's view (e.g., [viewController.view addSubview:anotherViewController.view]
) instead of pushing a new view controller onto the navigation controller's stack.
I'm using, Angular CLI: 8.1.2 Node: 12.14.1 OS: win32 x64
Strangely, this helped me
npm cache clean --force
npm uninstall @angular/cli
npm install @angular/[email protected]
This is a feature, not a bug.
See http://docs.python.org/howto/unicode.html, specifically the 'unicode type' section.
$('a[href*=#]').click(function(event){
$('html, body').animate({
scrollTop: $( $.attr(this, 'href') ).offset().top
}, 500);
event.preventDefault();
});
this worked perfect for me
You can also set the GPU in the command line so that you don't need to hard-code the device into your script (which may fail on systems without multiple GPUs). Say you want to run your script on GPU number 5, you can type the following on the command line and it will run your script just this once on GPU#5:
CUDA_VISIBLE_DEVICES=5, python test_script.py
use:
std::vector <Acard> playerHand;
everywhere qualify it by std::
or do:
using std::vector;
in your cpp file.
You have to do this because vector
is defined in the std
namespace and you do not tell your program to find it in std
namespace, you need to tell that.
In my case, the route signature was different from the method parameter. I had id, but I was accepting documentId as parameter, that caused the problem.
[Route("Documents/{id}")] <--- caused the webapi error
[Route("Documents/{documentId}")] <-- solved
public Document Get(string documentId)
{
..
}
I believe this works:
def cartesian_product(L):
if L:
return {(a,) + b for a in L[0]
for b in cartesian_product(L[1:])}
else:
return {()}
//a[contains(@prop,'Foo')]
Works if I use this XML to get results back.
<bla>
<a prop="Foo1">a</a>
<a prop="Foo2">b</a>
<a prop="3Foo">c</a>
<a prop="Bar">a</a>
</bla>
Edit: Another thing to note is that while the XPath above will return the correct answer for that particular xml, if you want to guarantee you only get the "a" elements in element "bla", you should as others have mentioned also use
/bla/a[contains(@prop,'Foo')]
This will search you all "a" elements in your entire xml document, regardless of being nested in a "blah" element
//a[contains(@prop,'Foo')]
I added this for the sake of thoroughness and in the spirit of stackoverflow. :)
I follow the following instruction to create a executable .jar in Eclipse. Then Run command "java -jar .jar " to launch the program.
It takes care of creating mainfest and includeing main class and library files parts for you.

Use C++ streams and restore state afterwards
This is a variation of How do I print bytes as hexadecimal? but:
main.cpp
#include <iomanip>
#include <iostream>
int main() {
int array[] = {0, 0x8, 0x10, 0x18};
constexpr size_t size = sizeof(array) / sizeof(array[0]);
// Sanity check decimal print.
for (size_t i = 0; i < size; ++i)
std::cout << array[i] << " ";
std::cout << std::endl;
// Hex print and restore default afterwards.
std::ios cout_state(nullptr);
cout_state.copyfmt(std::cout);
std::cout << std::hex << std::setfill('0') << std::setw(2);
for (size_t i = 0; i < size; ++i)
std::cout << array[i] << " ";
std::cout << std::endl;
std::cout.copyfmt(cout_state);
// Check that cout state was restored.
for (size_t i = 0; i < size; ++i)
std::cout << array[i] << " ";
std::cout << std::endl;
}
Compile and run:
g++ -o main.out -std=c++11 main.cpp
./main.out
Output:
0 8 16 24
00 8 10 18
0 8 16 24
Tested on Ubuntu 16.04, GCC 6.4.0.
MySQL has started deprecating SQL_CALC_FOUND_ROWS
functionality with version 8.0.17 onwards.
So, it is always preferred to consider executing your query with LIMIT
, and then a second query with COUNT(*)
and without LIMIT
to determine whether there are additional rows.
From docs:
The SQL_CALC_FOUND_ROWS query modifier and accompanying FOUND_ROWS() function are deprecated as of MySQL 8.0.17 and will be removed in a future MySQL version.
COUNT(*) is subject to certain optimizations. SQL_CALC_FOUND_ROWS causes some optimizations to be disabled.
Use these queries instead:
SELECT * FROM tbl_name WHERE id > 100 LIMIT 10; SELECT COUNT(*) WHERE id > 100;
Also, SQL_CALC_FOUND_ROWS
has been observed to having more issues generally, as explained in the MySQL WL# 12615 :
SQL_CALC_FOUND_ROWS has a number of problems. First of all, it's slow. Frequently, it would be cheaper to run the query with LIMIT and then a separate SELECT COUNT() for the same query, since COUNT() can make use of optimizations that can't be done when searching for the entire result set (e.g. filesort can be skipped for COUNT(*), whereas with CALC_FOUND_ROWS, we must disable some filesort optimizations to guarantee the right result)
More importantly, it has very unclear semantics in a number of situations. In particular, when a query has multiple query blocks (e.g. with UNION), there's simply no way to calculate the number of “would-have-been” rows at the same time as producing a valid query. As the iterator executor is progressing towards these kinds of queries, it is genuinely difficult to try to retain the same semantics. Furthermore, if there are multiple LIMITs in the query (e.g. for derived tables), it's not necessarily clear to which of them SQL_CALC_FOUND_ROWS should refer to. Thus, such nontrivial queries will necessarily get different semantics in the iterator executor compared to what they had before.
Finally, most of the use cases where SQL_CALC_FOUND_ROWS would seem useful should simply be solved by other mechanisms than LIMIT/OFFSET. E.g., a phone book should be paginated by letter (both in terms of UX and in terms of index use), not by record number. Discussions are increasingly infinite-scroll ordered by date (again allowing index use), not by paginated by post number. And so on.
I was having this problem when running from c#, on Windows 7, the "Interactive Services Detection" service was popping up when running a hidden powershell window as the SYSTEM account.
Using the "CreateNoWindow" parameter prevented the ISD service popping up it's warning.
process.StartInfo = new ProcessStartInfo("powershell.exe",
String.Format(@" -NoProfile -ExecutionPolicy unrestricted -encodedCommand ""{0}""",encodedCommand))
{
WorkingDirectory = executablePath,
UseShellExecute = false,
CreateNoWindow = true
};

The SmtpClient can be used by code:
SmtpClient mailer = new SmtpClient();
mailer.Host = "mail.youroutgoingsmtpserver.com";
mailer.Credentials = new System.Net.NetworkCredential("yourusername", "yourpassword");
In my projects I use following function to access cookies by name
function getCookie(cookie) {
return document.cookie.split(';').reduce(function(prev, c) {
var arr = c.split('=');
return (arr[0].trim() === cookie) ? arr[1] : prev;
}, undefined);
}
You don't necessarily need to force a re-render.
This might not help OP, but in my case I only needed to update the width
and height
attributes on my canvas (which you can't do with CSS).
It looks like this:
import React from 'react';
import styled from 'styled-components';
import {throttle} from 'lodash';
class Canvas extends React.Component {
componentDidMount() {
window.addEventListener('resize', this.resize);
this.resize();
}
componentWillUnmount() {
window.removeEventListener('resize', this.resize);
}
resize = throttle(() => {
this.canvas.width = this.canvas.parentNode.clientWidth;
this.canvas.height = this.canvas.parentNode.clientHeight;
},50)
setRef = node => {
this.canvas = node;
}
render() {
return <canvas className={this.props.className} ref={this.setRef} />;
}
}
export default styled(Canvas)`
cursor: crosshair;

Use create a temptable on data frame:
sqlContext.sql("select * from tempTable where column_old_value='None' ").show()
So use : column_old_value='None'
This was provided after installation of Sql Express 2019
Server=localhost\SQLEXPRESS;Database=master;Trusted_Connection=True;
So just use 'localhost\SQLEXPRESS' in server name and windows authentication worked for me.
In this line:
fund = fund * (1 + 0.01 * growthRates) + depositPerYear
growthRates is a sequence ([3,4,5,0,3]
). You can't multiply that sequence by a float (0.1). It looks like what you wanted to put there was i
.
Incidentally, i
is not a great name for that variable. Consider something more descriptive, like growthRate
or rate
.
function return_var_dump(){
// It works like var_dump, but it returns a string instead of printing it.
$args = func_get_args(); // For <5.3.0 support ...
ob_start();
call_user_func_array('var_dump', $args);
return ob_get_clean();
}
I just figured out how to do this:
It appears that when you add a parent folder to version control, Eclipse adds all sub-folders. Once the sub-folders are added to version control, it is not possible to ignore them.
Here's how to do it:
Right click on the top level folder and add to version control Right click on the child folder you want to ignore, revert Right click on the child folder you want to ignore, svn:ignore (which will now be available)
I just wrote a blog post on saving an object's data to Binary, XML, or Json. It sounds like you probably want to use Binary serialization, but perhaps you want the files to be edited outside of your app, in which case XML or Json might be better. Here are the functions to do it in the various formats. See my blog post for more details.
/// <summary>
/// Writes the given object instance to a binary file.
/// <para>Object type (and all child types) must be decorated with the [Serializable] attribute.</para>

/// </summary>
/// <typeparam name="T">The type of object being written to the XML file.</typeparam>
/// <param name="filePath">The file path to write the object instance to.</param>
/// <param name="objectToWrite">The object instance to write to the XML file.</param>
/// <param name="append">If false the file will be overwritten if it already exists. If true the contents will be appended to the file.</param>
public static void WriteToBinaryFile<T>(string filePath, T objectToWrite, bool append = false)
{
using (Stream stream = File.Open(filePath, append ? FileMode.Append : FileMode.Create))
{
var binaryFormatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
binaryFormatter.Serialize(stream, objectToWrite);
}
}

return (T)binaryFormatter.Deserialize(stream);
}
}

Fixing Error code 1206: The number of locks exceeds the lock table size.
In my case, I work with MySQL Workbench (5.6.17) running on Windows with WampServer 2.5.
For Windows/WampServer you have to edit the my.ini file (not the my.cnf file)
To locate this file go to Menu Server/Server Status (in MySQL Workbench) and look under Server Directories/ Base Directory
In my.ini file there are defined sections for different settings, look for section [mysqld] (create it if it does not exist) and add the command: innodb_buffer_pool_size=4G
[mysqld]
innodb_buffer_pool_size=4G
The size of the buffer_pool file will depend on your specific machine, in most cases, 2G or 4G will fix the problem.
Remember to restart the server so it takes the new configuration, it corrected the problem for me.
Hope it helps!
Simply replacing the src
attribute of the iframe element was not satisfactory in my case because one would see the old content until the new page is loaded. This works better if you want to give instant visual feedback:
var url = iframeEl.src;
iframeEl.src = 'about:blank';
setTimeout(function() {
iframeEl.src = url;
}, 10);
You can use the template syntax of ngFor
on groups
and the usual syntax inside it for the actual rows like:
<table>
<template let-group ngFor [ngForOf]="groups">
<tr *ngFor="let row of group.items">{{row}}</tr>
</template>
</table>
If you want to use an array, you have to keep a counter which contains the number of cars in the garage. Better use an ArrayList
instead of array:
List<Car> garage = new ArrayList<Car>();
garage.add(redCar);
figure (1)
hFig = figure(1);
set(gcf,'PaperPositionMode','auto')
set(hFig, 'Position', [0 0 xwidth ywidth])
plot(x,y)
print -depsc2 correlation.eps; % for saving in eps, look up options for saving as png or other formats you may need
This saves the figure in the dimensions specified

Make sure you have the proper emulator and Android version installed. That solved the problem for me.

Regarding the 64-bit system wanting 32-bit support. I don't find it so bizarre:
Although deployed to a 64-bit system, this doesn't mean all the referenced assemblies are necessarily 64-bit Crystal Reports assemblies. Further to that, the Crystal Reports assemblies are largely just wrappers to a collection of legacy DLLs upon which they are based. Many 32-bit DLLs are required by the primarily referenced assembly. The error message "can not load the assembly" involves these DLLs as well. To see visually what those are, go to www.dependencywalker.com and run 'Depends' on the assembly in question, directly on that IIS server.
You want to use a Set
or List
implementation (e.g. HashSet
, TreeSet
, etc, or ArrayList
, LinkedList
, etc..), since Java does not have dynamically sized arrays.
List<String> zoom = new ArrayList<>();
zoom.add("String 1");
zoom.add("String 2");
for (String z : zoom) {
System.err.println(z);
}
Edit: Here is a more succinct way to initialize your List with an arbitrary number of values using varargs:
List<String> zoom = Arrays.asList("String 1", "String 2", "String n");

There is a debugger tool that you can see you console message on top of you device screen. So you don't need connecting to any remote debugger that will slow down your animation or anything. Can check here:
https://github.com/fwon/RNVConsole
Or use expo to have a try https://snack.expo.io/SklJHMS3S
You can't multiply string and float.instead of you try as below.it works fine
totalAmount = salesAmount * float(salesTax)
I don't understand why other answers are about relative coordinates change, not absolute like OP asked in title.
$("#Friends").animate( {top:
"-=" + (parseInt($("#Friends").css("top")) - 100) + "px"
} );
There are two major libraries:
ZXing a library written in Java and then ported to Objective C / C++ (QR code only). And an other port to ObjC has been done, by TheLevelUp: ZXingObjC
ZBar an open source software for reading bar codes, C based.
According to my experiments, ZBar is far more accurate and fast than ZXing, at least on iPhone.
MrOBrian's answer shows why your current code doesn't work, with the missing trailing ]
and quotes, but here's an easier way to make it work:
onchange='mySelectHandler(this)'
And then:
function mySelectHandler(el){
var mySelect = $(el)
// get selected value
alert ("selected " + mySelect.val())
}
Or better still, remove the inline event handler altogether and bind the event handler with jQuery:
$('select[name="a[b]"]').change(function() {
var mySelect = $(this);
alert("selected " mySelect.val());
});
That last would need to be in a document.ready handler or in a script block that appears after the select element. If you want to run the same function for other selects simply change the selector to something that applies to all, e.g., all selects would be $('select')
, or all with a particular class would be $('select.someClass')
.
I suggest this discriminative question:
Is the open-source tool necessary in your process of making money?
Using a variant on @wisbucky's answer, I added the following as an alias to my ~/.gitconfig
file:
pruneitgood = "!f() { \
git remote prune origin; \
git branch -vv | perl -nae 'system(qw(git branch -d), $F[0]) if $F[3] eq q{gone]}'; \

With this, a simple git pruneitgood

In my case I got this message because there's a special char (&) in my connectionstring, remove it then everything's good.

You can use any commonly available hash algorithm (eg. SHA-1), which will give you a slightly longer result than what you need. Simply truncate the result to the desired length, which may be good enough.
For example, in Python:
>>> import hashlib
>>> hash = hashlib.sha1("my message".encode("UTF-8")).hexdigest()
>>> hash
'104ab42f1193c336aa2cf08a2c946d5c6fd0fcdb'
>>> hash[:10]
'104ab42f11'
Using simple regexp:
str=$(git status)
if [[ $str =~ .*Your\ branch\ is\ behind.*by.*commits,\ and\ can\ be\ fast-forwarded ]]; then
echo `date "+%Y-%m-%d %H:%M:%S"` "Needs pull"
else
echo "Code is up to date"
fi
Just adding this for multiple filters attaching to Q
object, if someone might be looking to it.
If a Q
object is provided, it must precede the definition of any keyword arguments. Otherwise its an invalid query. You should be careful when doing it.
an example would be
from django.db.models import Q
User.objects.filter(Q(income__gte=5000) | Q(income__isnull=True),category='income')
Here the OR condition and a filter with category of income is taken into account
You can use the following command:
svn status -q
According to svnbook:
With --quiet (-q), it prints only summary information about locally modified items.
WARNING: The output of this command only shows your modification. So I suggest to do a svn up
to get latest version of the file and then use svn status -q
to get the files you have modified.
You can also use:
p::before {
content: "";
padding-left: 30px;
}
And replace "p" with any other selector you have in mind.
Try os.chdir
os.chdir(path)
Change the current working directory to path. Availability: Unix, Windows.

For your specific example, if you want to do a one-to-one
relationship, you should change the next code in ReleaseDateType model:
@Column(nullable = true)
private Integer media_Id;
for:
@OneToOne(fetch = FetchType.LAZY)
@JoinColumn(name="CACHE_MEDIA_ID", nullable=true)
private CacheMedia cacheMedia ;
and in CacheMedia model you need to add:
@OneToOne(cascade=ALL, mappedBy="ReleaseDateType")
private ReleaseDateType releaseDateType;
then in your repository you should replace:
@Query("Select * from A a left join B b on a.id=b.id")
public List<ReleaseDateType> FindAllWithDescriptionQuery();
by:
//In this case a query annotation is not need since spring constructs the query from the method name
public List<ReleaseDateType> findByCacheMedia_Id(Integer id);
or by:
@Query("FROM ReleaseDateType AS rdt WHERE cm.rdt.cacheMedia.id = ?1") //This is using a named query method
public List<ReleaseDateType> FindAllWithDescriptionQuery(Integer id);
Or if you prefer to do a @OneToMany
and @ManyToOne
relation, you should change the next code in ReleaseDateType model:
@Column(nullable = true)
private Integer media_Id;
for:
@OneToMany(cascade=ALL, mappedBy="ReleaseDateType")
private List<CacheMedia> cacheMedias ;
and in CacheMedia model you need to add:
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name="RELEASE_DATE_TYPE_ID", nullable=true)
private ReleaseDateType releaseDateType;
then in your repository you should replace:
@Query("Select * from A a left join B b on a.id=b.id")
public List<ReleaseDateType> FindAllWithDescriptionQuery();
by:
//In this case a query annotation is not need since spring constructs the query from the method name
public List<ReleaseDateType> findByCacheMedias_Id(Integer id);
or by:
@Query("FROM ReleaseDateType AS rdt LEFT JOIN rdt.cacheMedias AS cm WHERE cm.id = ?1") //This is using a named query method
public List<ReleaseDateType> FindAllWithDescriptionQuery(Integer id);
For Swift 2.3,swift3,and swift4:
Create a perform Segue at didSelectRowAtindexPath
For Ex:
self.performSegue(withIdentifier: "uiView", sender: self)
After that Create a prepareforSegue function to catch the Destination segue and pass the value:
Ex:
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "uiView"{
let destView = segue.destination as! WebViewController
let indexpath = self.newsTableView.indexPathForSelectedRow
let indexurl = tableDatalist[(indexpath?.row)!].link
destView.UrlRec = indexurl
//let url =
}
}
You need to create a variable named UrlRec in Destination ViewController
You can just use []
:
var valueAtIndex1 = myValues[1];
Just add the column names, yes you can use Null instead but is is a very bad idea to not use column names in any insert, ever.

There is no error when I use your code,

I see it is an old thread but I had the same error.
I found the explanation here: http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html
void execSQL(String sql)
Execute a single SQL statement that is NOT a SELECT or any other SQL statement that returns data.
void execSQL(String sql, Object[] bindArgs)
Execute a single SQL statement that is NOT a SELECT/INSERT/UPDATE/DELETE.
Use -C
option of tar:
tar zxvf <yourfile>.tar.gz -C /usr/src/

You want your UI updates to happen in the already-existent UI thread.
The best way is to use a Handler that uses postDelayed to run a Runnable after a delay (each run schedules the next); clear the callback with removeCallbacks.
You're already looking in the right place, so look at it again, perhaps clarify why that code sample isn't what you want. (See also the identical article at Updating the UI from a Timer).
I had a similar problem with another library and the reason why it didn't found it, was that I didn't run the make install (after running ./configure and make) for that library. The make install may require root privileges (in this case use: sudo make install). After running the make install you should have the so files in the correct folder, i.e. here /usr/local/lib and not in the folder mentioned by you.
Solution for those who are interested in sending params and headers in GET request
$http.get('https://www.your-website.com/api/users.json', {
params: {page: 1, limit: 100, sort: 'name', direction: 'desc'},
headers: {'Authorization': 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
}
)
.then(function(response) {
// Request completed successfully
}, function(x) {
// Request error
});
Complete service example will look like this
var mainApp = angular.module("mainApp", []);
mainApp.service('UserService', function($http, $q){
this.getUsers = function(page = 1, limit = 100, sort = 'id', direction = 'desc') {
var dfrd = $q.defer();
$http.get('https://www.your-website.com/api/users.json',
{
params:{page: page, limit: limit, sort: sort, direction: direction},
headers: {Authorization: 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
}
)
.then(function(response) {
if ( response.data.success == true ) {
} else {
}
}, function(x) {
dfrd.reject(true);
});
return dfrd.promise;
}
});
has_key
was removed in Python 3. From the documentation:
- Removed
dict.has_key()
– use thein
operator instead.
Here's an example:
if start not in graph:
return None
Not the best way, but at lease does not need external tools (except grep, which is standard on *nix boxes anyway)
sqlite3 database.db3 .dump | grep '^INSERT INTO "tablename"'
but you do need to do this command for each table you are looking for though.
Note that this does not include schema.
Yet another possible root cause for this error is if the namespace for the area registration class does not match the namespace for the controller.
E.g. correct naming on controller class:
namespace MySystem.Areas.Customers
{
public class CustomersController : Controller
{
...
}
}
With incorrect naming on area registration class:
namespace MySystem.Areas.Shop
{
public class CustomersAreaRegistration : AreaRegistration
{
...
}
}
(Namespace above should be MySystem.Areas.Customers
.)
Will I ever learn to stop copy and pasting code? Probably not.

Darin Dimitrov's answer is correct. Just an addition:
Response.AppendHeader("Content-Disposition", cd.ToString());
may cause the browser to fail rendering the file if your response already contains a "Content-Disposition" header. In that case, you may want to use:
Response.Headers.Add("Content-Disposition", cd.ToString());
chsh -s $(which zsh)
You'll be prompted for your password, but once you update your settings any new iTerm/Terminal sessions you start on that machine will default to zsh.
The transforms are SVG transforms (for details, have a look at the standard; here are some examples). Basically, scale and translate apply the respective transformations to the coordinate system, which should work as expected in most cases. You can apply more than one transform however (e.g. first scale and then translate) and then the result might not be what you expect.
When working with the transforms, keep in mind that they transform the coordinate system. In principle, what you say is true -- if you apply a scale > 1 to an object, it will look bigger and a translate will move it to a different position relative to the other objects.
It's also possible that you have included /bin in your JAVA_HOME setting, and Ant is adding /bin to it - thereby not finding any exe's. It's happened to me :}
Using "focus" will give keyboard users the same effect that mouse users get when they hover with a mouse. "Active" is needed to get the same effect in Internet Explorer.
The reality is, these states do not work as they should for all users. Not using all three selectors creates accessibility issues for many keyboard-only users who are physically unable to use a mouse. I invite you to take the #nomouse challenge (nomouse dot org).
You can generate an AWR (automatic workload repository) report from the database.
Run from the SQL*Plus command line:
SQL> @$ORACLE_HOME/rdbms/admin/awrrpt.sql
Read the document related to how to generate & understand an AWR report. It will give a complete view of database performance and resource issues. Once we are familiar with the AWR report it will be helpful to find Top SQL which is consuming resources.
Also, in the 12C EM Express UI we can generate an AWR.
Maybe you want set -e
:
www.davidpashley.com/articles/writing-robust-shell-scripts.html#id2382181:
This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. Again, for readability you may want to use set -o errexit.

You can use jackson api for the conversion
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.9.4</version>
</dependency>
add above maven dependency in your POM, In your main method create ObjectMapper
ObjectMapper mapper = new ObjectMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
later we nee to add our POJO class to the mapper
String json = mapper.writeValueAsString(pojo);
I also faced this issue after I updated to AS2.0. I found that it is because of the instant run
enabled. So my solution is to disable the "instant run". and it worked. To disable "instant run", you can go to Preference Dialog
( May be Setting dialog on Windows), then select Build, Execution, Deployment
> Instant Run
, and uncheck all the checkbox to disable Instant Run
.
This is my temporary solution and it may help you. Later, I'll find a better way to this issue.
A better solution instead of disabling instant run
.
Remove the .idea
folder and .gradle
folder, then click button Sync Project with Gradle Files
(or through the menu File
-> Sync Project with Gradle Files
), after this process finished, you are able to run your app as normal.
Good Luck~
The SQL standard way to implement recursive queries, as implemented e.g. by IBM DB2 and SQL Server, is the WITH
clause. See this article for one example of translating a CONNECT BY
into a WITH
(technically a recursive CTE) -- the example is for DB2 but I believe it will work on SQL Server as well.
Edit: apparently the original querant requires a specific example, here's one from the IBM site whose URL I already gave. Given a table:
CREATE TABLE emp(empid INTEGER NOT NULL PRIMARY KEY,
name VARCHAR(10),
salary DECIMAL(9, 2),
mgrid INTEGER);
where mgrid
references an employee's manager's empid
, the task is, get the names of everybody who reports directly or indirectly to Joan
. In Oracle, that's a simple CONNECT
:
SELECT name
FROM emp
START WITH name = 'Joan'
CONNECT BY PRIOR empid = mgrid
In SQL Server, IBM DB2, or PostgreSQL 8.4 (as well as in the SQL standard, for what that's worth;-), the perfectly equivalent solution is instead a recursive query (more complex syntax, but, actually, even more power and flexibility):
WITH n(empid, name) AS
(SELECT empid, name
FROM emp
WHERE name = 'Joan'
UNION ALL
SELECT nplus1.empid, nplus1.name
FROM emp as nplus1, n
WHERE n.empid = nplus1.mgrid)
SELECT name FROM n
Oracle's START WITH
clause becomes the first nested SELECT
, the base case of the recursion, to be UNION
ed with the recursive part which is just another SELECT
.
SQL Server's specific flavor of WITH
is of course documented on MSDN, which also gives guidelines and limitations for using this keyword, as well as several examples.
Or use the FileInfo as suggested in In C# check that filename is possibly valid (not that it exists).
And then there is this...
( document.exitPointerLock || Function )();
$($('#listItem').contents()[0]).text()
Short variant of Stuart answer.
or with get()
$($('#listItem').contents().get(0)).text()
This is a simple solution
<ul class="nav navbar-nav navbar-right navbar-default menu">
<li ng-class="menuIndice == 1 ? 'active':''">
<a ng-click="menuIndice = 1" href="#/item1">item1</a>
</li>
<li ng-class="menuIndice == 2 ? 'active':''">
<a ng-click="menuIndice = 2" href="#/item2">item2</a>
</li>
<li ng-class="menuIndice == 3 ? 'active':''">
<a ng-click="menuIndice = 3" href="#/item3">item3</a>
</li>
</ul>
you could use a defaultdict. It will let you set dictionary values without worrying if the key already exists. If you access a key that has not been initialized yet it will return a value you specify (in the below example it will return None)
from collections import defaultdict
your_dict = defaultdict(lambda : None)
i fixed my issue by override legend style as Below
.ui-fieldset-legend
{
font-size: 1.2em;
font-weight: bold;
display: inline-block;
width: auto;`enter code here`
}
date = datetime.datetime(2003,8,1,12,4,5)
for i in range(5):
date += datetime.timedelta(days=1)
print(date)
If you return "false" from your function it'll stop the event bubbling, so only your first event handler will get triggered (ie. your anchor will not see the click).
$("div.clickable").click(
function()
{
window.location = $(this).attr("url");
return false;
});
See event.preventDefault() vs. return false for details on return false vs. preventDefault.
You may try the following code for capturing the closing event for any item : page, dialog etc.
$("#dialog").live('pagehide', function(event, ui) {
$(this).hide();
});
From you own project.
npx nodemon [your-app.js]
With a local installation, nodemon will not be available in your system path. Instead, the local installation of nodemon can be run by calling it from within an npm script (such as npm start
) or using npx nodemon
.
OR
Create a simple symbolik link
ln -s /Users/YourUsername/.npm-global/bin/nodemon /usr/local/bin
ln -s [from: where is you install 'nodemon'] [to: folder where are general module for node]
node : v12.1.0
npm : 6.9.0
When you create an initialization of the ResourceBundle, you can do this way also.
For testing and development I have created a properties file under \src with the name prp.properties.
Use this way:
ResourceBundle rb = ResourceBundle.getBundle("prp");
Naming convention and stuff:
http://192.9.162.55/developer/technicalArticles/Intl/ResourceBundles/
The explanations given here are correct. I just wanted to add that this problem might be because you copied the code from somewhere, from a website or a pdf file due to which there are some invalid characters in the code.
Try to find those invalid characters, or just retype the code if you can't. It will definitely compile then.

I used these options to convert to the H.264/AAC .mp4 format for HTML5 playback (I think it may help other guys with this problem in some way):
ffmpeg -i input.flv -vcodec mpeg4 -acodec aac output.mp4
UPDATE
As @LordNeckbeard mentioned, the previous line will produce MPEG-4 Part 2
(back in 2012 that worked somehow, I don't remember/understand why). Use the libx264
encoder to produce the proper video with H.264/AAC. To test the output file you can just drag it to a browser window and it should playback just fine.
ffmpeg -i input.flv -vcodec libx264 -acodec aac output.mp4

Not easily done I am afraid. The problem is Css cannot replace the arrow in a select as this is rendered by the browser. But you can build a new control from div and input elements and Javascript to perform the same function as the select.
Try looking at some of the autocomplete plugins for Jquery for example.
Otherwise there is some info on the select element here:

You can avoid std::bind
doing this:
std::function<void(void)> f = [this]-> {Foo::doSomething();}
this worked for me:

I do get this message :

but I don't have to worry about having an empty directory hanging around.
Well for me the problem got resolved by adding the jars in my APACHE/TOMCAT/lib folder ! .
I recently wanted to do this and found that I was not happy with any of the answers here.
If you follow Marc's advice and set the output-type to Console Application there are two problems:
1) If you launch the application from Explorer, you get an annoying console window behind your Form which doesn't go away until your program exits. We can mitigate this problem by calling FreeConsole prior to showing the GUI (Application.Run). The annoyance here is that the console window still appears. It immediately goes away, but is there for a moment none-the-less.
2) If you launch it from a console, and display a GUI, the console is blocked until the GUI exits. This is because the console (cmd.exe) thinks it should launch Console apps synchronously and Windows apps asynchronously (the unix equivalent of "myprocess &").
If you leave the output-type as Windows Application, but correctly call AttachConsole, you don't get a second console window when invoked from a console and you don't get the unnecessary console when invoked from Explorer. The correct way to call AttachConsole is to pass -1 to it. This causes our process to attach to the console of our parent process (the console window that launched us).
However, this has two different problems:
1) Because the console launches Windows apps in the background, it immediately displays the prompt and allows further input. On the one hand this is good news, the console is not blocked on your GUI app, but in the case where you want to dump output to the console and never show the GUI, your program's output comes after the prompt and no new prompt is displayed when you're done. This looks a bit confusing, not to mention that your "console app" is running in the background and the user is free to execute other commands while it's running.
2) Stream redirection gets messed up as well, e.g. "myapp some parameters > somefile" fails to redirect. The stream redirection problem requires a significant amount of p/Invoke to fixup the standard handles, but it is solvable.
After many hours of hunting and experimenting, I've come to the conclusion that there is no way to do this perfectly. You simply cannot get all the benefits of both console and window without any side effects. It's a matter of picking which side effects are least annoying for your application's purposes.
Should declare logger like this:
private final static Logger LOGGER = Logger.getLogger(MyClass.class.getName());
so if you refactor your class name it follows.
I wrote an article about java logger with examples here.
