Set ReadTimeout or WriteTimeout property on the NetworkStream for synchronous reads/writes. Updating OP's code:
try
{
TcpClient client = new TcpClient("remotehost", this.Port);
Byte[] data = System.Text.Encoding.Unicode.GetBytes(this.Message);
NetworkStream stream = client.GetStream();
stream.WriteTimeout = 1000; // <------- 1 second timeout
stream.ReadTimeout = 1000; // <------- 1 second timeout
stream.Write(data, 0, data.Length);
data = new Byte[512];
Int32 bytes = stream.Read(data, 0, data.Length);
this.Response = System.Text.Encoding.Unicode.GetString(data, 0, bytes);
stream.Close();
client.Close();
FireSentEvent(); //Notifies of success
}
catch (Exception ex)
{
// Throws IOException on stream read/write timeout
FireFailedEvent(ex); //Notifies of failure
}
First of all, TCP does not guarantee that everything that you send will be received with the same read at the other end. It only guarantees that all bytes that you send will arrive and in the correct order.
Therefore, you will need to keep building up a buffer when reading from the stream. You will also have to know how large each message is.
The simplest ever is to use a non-typeable ASCII character to mark the end of the packet and look for it in the received data.
string hostname = "localhost";
int portno = 9081;
IPAddress ipa = (IPAddress) Dns.GetHostAddresses(hostname)[0];
try
{
System.Net.Sockets.Socket sock = new System.Net.Sockets.Socket(System.Net.Sockets.AddressFamily.InterNetwork, System.Net.Sockets.SocketType.Stream, System.Net.Sockets.ProtocolType.Tcp);
sock.Connect(ipa, portno);
if (sock.Connected == true) // Port is in use and connection is successful
MessageBox.Show("Port is Closed");
sock.Close();
}
catch (System.Net.Sockets.SocketException ex)
{
if (ex.ErrorCode == 10061) // Port is unused and could not establish connection
MessageBox.Show("Port is Open!");
else
MessageBox.Show(ex.Message);
}
Setting the underlying socket ReceiveTimeout
property did the trick. You can access it like this: yourTcpClient.Client.ReceiveTimeout
. You can read the docs for more information.
Now the code will only "sleep" as long as needed for some data to arrive in the socket, or it will raise an exception if no data arrives, at the beginning of a read operation, for more than 20ms. I can tweak this timeout if needed. Now I'm not paying the 20ms price in every iteration, I'm only paying it at the last read operation. Since I have the content-length of the message in the first bytes read from the server I can use it to tweak it even more and not try to read if all expected data has been already received.
I find using ReceiveTimeout much easier than implementing asynchronous read... Here is the working code:
string SendCmd(string cmd, string ip, int port)
{
var client = new TcpClient(ip, port);
var data = Encoding.GetEncoding(1252).GetBytes(cmd);
var stm = client.GetStream();
stm.Write(data, 0, data.Length);
byte[] resp = new byte[2048];
var memStream = new MemoryStream();
var bytes = 0;
client.Client.ReceiveTimeout = 20;
do
{
try
{
bytes = stm.Read(resp, 0, resp.Length);
memStream.Write(resp, 0, bytes);
}
catch (IOException ex)
{
// if the ReceiveTimeout is reached an IOException will be raised...
// with an InnerException of type SocketException and ErrorCode 10060
var socketExept = ex.InnerException as SocketException;
if (socketExept == null || socketExept.ErrorCode != 10060)
// if it's not the "expected" exception, let's not hide the error
throw ex;
// if it is the receive timeout, then reading ended
bytes = 0;
}
} while (bytes > 0);
return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}
This will be possible via the navigator interface as shown below:
navigator.tcpPermission.requestPermission({remoteAddress:"127.0.0.1", remotePort:6789}).then(
() => {
// Permission was granted
// Create a new TCP client socket and connect to remote host
var mySocket = new TCPSocket("127.0.0.1", 6789);
// Send data to server
mySocket.writeable.write("Hello World").then(
() => {
// Data sent sucessfully, wait for response
console.log("Data has been sent to server");
mySocket.readable.getReader().read().then(
({ value, done }) => {
if (!done) {
// Response received, log it:
console.log("Data received from server:" + value);
}
// Close the TCP connection
mySocket.close();
}
);
},
e => console.error("Sending error: ", e)
);
}
);
More details are outlined in the w3.org tcp-udp-sockets documentation.
http://raw-sockets.sysapps.org/#interface-tcpsocket
https://www.w3.org/TR/tcp-udp-sockets/
Another alternative is to use Chrome Sockets
Creating connections
chrome.sockets.tcp.create({}, function(createInfo) {
chrome.sockets.tcp.connect(createInfo.socketId,
IP, PORT, onConnectedCallback);
});
Sending data
chrome.sockets.tcp.send(socketId, arrayBuffer, onSentCallback);
Receiving data
chrome.sockets.tcp.onReceive.addListener(function(info) {
if (info.socketId != socketId)
return;
// info.data is an arrayBuffer.
});
You can use also attempt to use HTML5 Web Sockets
(Although this is not direct TCP communication):
var connection = new WebSocket('ws://IPAddress:Port');
connection.onopen = function () {
connection.send('Ping'); // Send the message 'Ping' to the server
};
http://www.html5rocks.com/en/tutorials/websockets/basics/
Your server must also be listening with a WebSocket server such as pywebsocket, alternatively you can write your own as outlined at Mozilla
The first problem with your script is that you have to put a space after the [
.
Type type [
to see what is really happening. It should tell you that [
is an alias to test
command, so [ ]
in bash is not some special syntax for conditionals, it is just a command on its own. What you should prefer in bash is [[ ]]
. This common pitfall is greatly explained here and here.
Another problem is that you didn't quote "$f"
which might become a problem later. This is explained here
You can use arithmetic expressions in if
, so you don't have to use [ ]
or [[ ]]
at all in some cases. More info here
Also there's no need to use \n
in every echo
, because echo
places newlines by default. If you want TWO newlines to appear, then use echo -e 'start\n'
or echo $'start\n'
. This $''
syntax is explained here
To make it completely perfect you should place --
before arbitrary filenames, otherwise rm
might treat it as a parameter if the file name starts with dashes. This is explained here.
So here's your script:
#!/bin/bash
echo "start"
for f in *.jpg
do
fname="${f##*/}"
echo "fname is $fname"
if (( fname % 2 == 1 )); then
echo "removing $fname"
rm -- "$f"
fi
done
Below is an example of multiple figures that I used recently in Latex. You need to call these packages
\usepackage{graphicx}
\usepackage{subfig})
\begin{figure}[H]%
\centering
\subfloat[Row1]{{\includegraphics[scale=.36]{1.png} }}%
\subfloat[Row2]{{\includegraphics[scale=.36]{2.png} }}%
\subfloat[Row3]{{\includegraphics[scale=.36]{3.png} }}%
\hfill
\subfloat[Row4]{{\includegraphics[scale=0.37]{4.png} }}%
\subfloat[Row5]{{\includegraphics[scale=0.37]{5.png} }}%
\caption{Multiple figures in latex.}%

You can add a UITapGestureRecognizer
to the imageView, just drag one into your Storyboard/xib, Ctrl-drag from the imageView to the gestureRecognizer, and Ctrl-drag from the gestureRecognizer to the Swift-file to make an IBAction
.
You'll also need to enable user interactions on the UIImageView
, as shown in this image:
Use trigger
to fire your own event. When ever you change class add trigger with name
$("#main").on('click', function () {
$("#chld").addClass("bgcolorRed").trigger("cssFontSet");
});
$('#chld').on('cssFontSet', function () {
alert("Red bg set ");
});
You (as in the process that runs b.php
, either you through CLI
or a webserver) need write access to the directory in which the files are located. You are updating the directory content, so access to the file is not enough.
Note that if you use the PHP chmod()
function to set the mode of a file or folder to 777
you should use 0777
to make sure the number is correctly interpreted as an octal number.
apply
and transform
There are two major differences between the transform
and apply
groupby methods.
apply
implicitly passes all the columns for each group as a DataFrame to the custom function.transform
passes each column for each group individually as a Series to the custom function.apply
can return a scalar, or a Series or DataFrame (or numpy array or even list).transform
must return a sequence (a one dimensional Series, array or list) the same length as the group.So, transform
works on just one Series at a time and apply
works on the entire DataFrame at once.
It can help quite a bit to inspect the input to your custom function passed to apply
or transform
.
Let's create some sample data and inspect the groups so that you can see what I am talking about:
import pandas as pd
import numpy as np
df = pd.DataFrame({'State':['Texas', 'Texas', 'Florida', 'Florida'],
'a':[4,5,1,3], 'b':[6,10,3,11]})
State a b
0 Texas 4 6
1 Texas 5 10
2 Florida 1 3
3 Florida 3 11
Let's create a simple custom function that prints out the type of the implicitly passed object and then raised an error so that execution can be stopped.
def inspect(x):
print(type(x))
raise
Now let's pass this function to both the groupby apply
and transform
methods to see what object is passed to it:
df.groupby('State').apply(inspect)
<class 'pandas.core.frame.DataFrame'>
<class 'pandas.core.frame.DataFrame'>
RuntimeError
As you can see, a DataFrame is passed into the inspect
function. You might be wondering why the type, DataFrame, got printed out twice. Pandas runs the first group twice. It does this to determine if there is a fast way to complete the computation or not. This is a minor detail that you shouldn't worry about.
Now, let's do the same thing with transform
df.groupby('State').transform(inspect)
<class 'pandas.core.series.Series'>
<class 'pandas.core.series.Series'>
RuntimeError
It is passed a Series - a totally different Pandas object.
So, transform
is only allowed to work with a single Series at a time. It is impossible for it to act on two columns at the same time. So, if we try and subtract column a
from b
inside of our custom function we would get an error with transform
. See below:
def subtract_two(x):
return x['a'] - x['b']
df.groupby('State').transform(subtract_two)
KeyError: ('a', 'occurred at index a')
We get a KeyError as pandas is attempting to find the Series index a
which does not exist. You can complete this operation with apply
as it has the entire DataFrame:
df.groupby('State').apply(subtract_two)
State
Florida 2 -2
3 -8
Texas 0 -2
1 -5
dtype: int64
The output is a Series and a little confusing as the original index is kept, but we have access to all columns.
It can help even more to display the entire pandas object within the custom function, so you can see exactly what you are operating with. You can use print
statements by I like to use the display
function from the IPython.display
module so that the DataFrames get nicely outputted in HTML in a jupyter notebook:
from IPython.display import display
def subtract_two(x):
display(x)
return x['a'] - x['b']
The other difference is that transform
must return a single dimensional sequence the same size as the group. In this particular instance, each group has two rows, so transform
must return a sequence of two rows. If it does not then an error is raised:
def return_three(x):
return np.array([1, 2, 3])
df.groupby('State').transform(return_three)
ValueError: transform must return a scalar value for each group
The error message is not really descriptive of the problem. You must return a sequence the same length as the group. So, a function like this would work:
def rand_group_len(x):
return np.random.rand(len(x))
df.groupby('State').transform(rand_group_len)
a b
0 0.962070 0.151440
1 0.440956 0.782176
2 0.642218 0.483257
3 0.056047 0.238208
transform
If you return just a single scalar from your custom function, then transform
will use it for each of the rows in the group:
def group_sum(x):
return x.sum()
df.groupby('State').transform(group_sum)
a b
0 9 16
1 9 16
2 4 14
3 4 14
John's answer won't produce .txt files as the OP wants. Use:
split -b=1M -d file.txt file --additional-suffix=.txt
You can accomplish this (if I understand what you are trying to do) using dynamic SQL.
The trick is that you need to create a string containing the SQL statement. That's because the tablename has to specified in the actual SQL text, when you execute the statement. The table references and column references can't be supplied as parameters, those have to appear in the SQL text.
So you can use something like this approach:
SET @stmt = 'INSERT INTO @tmpTbl1 SELECT ' + @KeyValue
+ ' AS fld1 FROM tbl' + @KeyValue
EXEC (@stmt)
First, we create a SQL statement as a string. Given a @KeyValue of 'Foo', that would create a string containing:
'INSERT INTO @tmpTbl1 SELECT Foo AS fld1 FROM tblFoo'
At this point, it's just a string. But we can execute the contents of the string, as a dynamic SQL statement, using EXECUTE
(or EXEC
for short).
The old-school sp_executesql
procedure is an alternative to EXEC, another way to execute dymamic SQL, which also allows you to pass parameters, rather than specifying all values as literals in the text of the statement.
FOLLOWUP
EBarr points out (correctly and importantly) that this approach is susceptible to SQL Injection.
Consider what would happen if @KeyValue
contained the string:
'1 AS foo; DROP TABLE students; -- '
The string we would produce as a SQL statement would be:
'INSERT INTO @tmpTbl1 SELECT 1 AS foo; DROP TABLE students; -- AS fld1 ...'
When we EXECUTE that string as a SQL statement:
INSERT INTO @tmpTbl1 SELECT 1 AS foo;
DROP TABLE students;
-- AS fld1 FROM tbl1 AS foo; DROP ...
And it's not just a DROP TABLE that could be injected. Any SQL could be injected, and it might be much more subtle and even more nefarious. (The first attacks can be attempts to retreive information about tables and columns, followed by attempts to retrieve data (email addresses, account numbers, etc.)
One way to address this vulnerability is to validate the contents of @KeyValue, say it should contain only alphabetic and numeric characters (e.g. check for any characters not in those ranges using LIKE '%[^A-Za-z0-9]%'
. If an illegal character is found, then reject the value, and exit without executing any SQL.
try the following code:
this.cloneArray= [...this.OriginalArray]
The standard way is to use audio/mpeg
which is something like this in your PHP header function ...
header('Content-Type: audio/mpeg');
Here is an in place replaceAll that will modify the passed in StringBuilder. I thought that I would post this as I was looking to do replaceAll with out creating a new String.
public static void replaceAll(StringBuilder sb, Pattern pattern, String replacement) {
Matcher m = pattern.matcher(sb);
while(m.find()) {
sb.replace(m.start(), m.end(), replacement);
}
}
I was shocked how simple the code to do this was (for some reason I thought changing the StringBuilder while using the matcher would throw of the group start/end but it does not).
This is probably faster than the other regex answers because the pattern is already compiled and your not creating a new String but I didn't do any benchmarking.

If you have created directory and sub-directory, follow the steps below and please keep in mind all directory must have __init__.py
to get it recognized as a directory.
In your script, include import sys
and sys.path
, you will be able to see all the paths available to Python. You must be able to see your current working directory.
Now import sub-directory and respective module that you want to use using: import subdir.subdir.modulename as abc
and now you can use the methods in that module.
As an example, you can see in this screenshot I have one parent directory and two sub-directories and under second sub-directories I have the module CommonFunction
. On the right my console shows that after execution of sys.path
, I can see my working directory.
If your input is a child element of the label
and you have more than one labels, you can combine @Mike's trick with Flexbox
+ order
.
label.switchLabel {
display: flex;
justify-content: space-between;
width: 150px;
}
.switchLabel .left { order: 1; }
.switchLabel .switch { order: 2; }
.switchLabel .right { order: 3; }
/* sibling selector ~ */
.switchLabel .switch:not(:checked) ~ span.left { color: lightblue }
.switchLabel .switch:checked ~ span.right { color: lightblue }
/* style the switch */
:root {
--radio-size: 14px;
}
.switchLabel input.switch {
width: var(--radio-size);
height: var(--radio-size);
border-radius: 50%;
border: 1px solid #999999;
box-sizing: border-box;

box-shadow: calc(var(--radio-size) / 2) 0 0 0 gray, calc(var(--radio-size) / 4) 0 0 0 gray;
margin: 0 calc(5px + var(--radio-size) / 2) 0 5px;
}
.switchLabel input.switch:checked {
box-shadow: calc(-1 * var(--radio-size) / 2) 0 0 0 gray, calc(-1 * var(--radio-size) / 4) 0 0 0 gray;

See it on JSFiddle.
note: Sibling selector only works within the same parent. To work around this, you can make the input hidden at top-level using @Nathan Blair hack.
Specifying a flex attribute to the container worked for me:
.container {
flex: 0 0 auto;
}
This ensures the height is set and doesn't grow either.

First things first ,
they are not always equal
select 'Hello' from dual where 'Hello ' like 'Hello';
select 'Hello' from dual where 'Hello ' = 'Hello';
when things are not always equal , talking about their performance isn't that relevant.
If you are working on strings and only char variables , then you can talk about performance . But don't use like and "=" as being generally interchangeable .
As you would have seen in many posts ( above and other questions) , in cases when they are equal the performance of like is slower owing to pattern matching (collation)
def search(myDict, lookup):
a=[]
for key, value in myDict.items():
for v in value:
if lookup in v:
a.append(key)
a=list(set(a))
return a
if the research involves more keys maybe you should create a list with all the keys

In addition to answer of @jww, I would like to say that the configuration in openssl-ca.cnf,
default_days = 1000 # How long to certify for
defines the default number of days the certificate signed by this root-ca will be valid. To set the validity of root-ca itself you should use '-days n' option in:
openssl req -x509 -days 3000 -config openssl-ca.cnf -newkey rsa:4096 -sha256 -nodes -out cacert.pem -outform PEM
Failing to do so, your root-ca will be valid for only the default one month and any certificate signed by this root CA will also have validity of one month.

textBox1.Text += ("brown\r\n");
textBox1.Text += ("brwn");
This will produce the two entries on separate lines.
subprocess.Popen
takes a cwd
argument to set the Current Working Directory; you'll also want to escape your backslashes ('d:\\test\\local'
), or use r'd:\test\local'
so that the backslashes aren't interpreted as escape sequences by Python. The way you have it written, the \t
part will be translated to a tab.
So, your new line should look like:
subprocess.Popen(r'c:\mytool\tool.exe', cwd=r'd:\test\local')
To use your Python script path as cwd, import os
and define cwd using this:
os.path.dirname(os.path.realpath(__file__))
Assuming that you do not have the log file from the expdp job that generated the file in the first place, the easiest option would probably be to use the SQLFILE parameter to have impdp generate a file of DDL (based on a full import). Then you can grab the schema names from that file. Not ideal, of course, since impdp has to read the entire dump file to extract the DDL and then again to get to the schema you're interested in, and you have to do a bit of text file searching for the various CREATE USER statements, but it should be doable.
With this you can remove the column
and store variable
into another variable
.
df = subset(data, select = -c(genome) )
SET @sql =
CONCAT( 'INSERT INTO <table_name> (',
(
SELECT GROUP_CONCAT( CONCAT('`',COLUMN_NAME,'`') )
FROM information_schema.columns
WHERE table_schema = <database_name>
AND table_name = <table_name>
AND column_name NOT IN ('id')
), ') SELECT ',
(
SELECT GROUP_CONCAT(CONCAT('`',COLUMN_NAME,'`'))
FROM information_schema.columns
WHERE table_schema = <database_name>
AND table_name = <table_source_name>
AND column_name NOT IN ('id')
),' from <table_source_name> WHERE <testcolumn> = <testvalue>' );
PREPARE stmt1 FROM @sql;
execute stmt1;
Of course replace <> values with real values, and watch your quotes.
The documentation could help you : http://java.sun.com/j2se/1.5.0/docs/api/javax/xml/parsers/DocumentBuilder.html
The method DocumentBuilder.parse(String)
takes a URI and tries to open it. If you want to directly give the content, you have to give it an InputStream
or Reader
, for example a StringReader
. ... Welcome to the Java standard levels of indirections !
Basically :
DocumentBuilder db = ...;
String xml = ...;
db.parse(new InputSource(new StringReader(xml)));
Note that if you read your XML from a file, you can directly give the File
object to DocumentBuilder.parse()
.
As a side note, this is a pattern you will encounter a lot in Java. Usually, most API work with Streams more than with Strings. Using Streams means that potentially not all the content has to be loaded in memory at the same time, which can be a great idea !

Idk anything about 16 character hex strings....
using System;
using System.Security.Cryptography;
using System.Text;
But here is mine for creating MD5 hash in one line.
string hash = BitConverter.ToString(MD5.Create().ComputeHash(Encoding.ASCII.GetBytes("THIS STRING TO MD5"))).Replace("-","");
I'm assuming this should work. This will actually put it in the column in your database
UPDATE yourTable yt SET yt.Total = (yt.Pieces * yt.Price)
If you want to retrieve the 2 values from the database and put your multiplication in the third column of the result only, then
SELECT yt.Pieces, yt.Price, (yt.Pieces * yt.Price) as 'Total' FROM yourTable yt
will be your friend
A bit unrelated answer to OP but for people like me with a somewhat similar problem.
Use Case: Ubuntu (C, Clion, Auto-completion):
I had the same error,
CMake Error: Cannot determine link language for target "hello".
set_target_properties(hello PROPERTIES LINKER_LANGUAGE C)
help fixes that problem but the headers aren't included to the project and the autocompletion wont work.
This is what i had
cmake_minimum_required(VERSION 3.5)
project(hello)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES ./)
add_executable(hello ${SOURCE_FILES})
set_target_properties(hello PROPERTIES LINKER_LANGUAGE C)
No errors but not what i needed, i realized including a single file as source will get me autocompletion as well as it will set the linker to C
.
cmake_minimum_required(VERSION 3.5)
project(hello)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES ./1_helloworld.c)
add_executable(hello ${SOURCE_FILES})
Simply put this in your code:
Application.WorksheetFunction.Subtotal(3, Range("A2:A500000"))
Make sure you apply the correct range, but just keep it to ONE column
You'll need to open the workbook to refer to it.
Sub Setwbk()
Dim wbk As Workbook
Set wbk = Workbooks.Open("F:\Quarterly Reports\2012 Reports\New Reports\ _

End Sub
* Follow Doug's answer if the workbook is already open. For the sake of making this answer as complete as possible, I'm including my comment on his answer:
Why do I have to "set" it?
Set
is how VBA assigns object variables. Since a Range
and a Workbook
/Worksheet
are objects, you must use Set
with these.
Table: Table is a preliminary storage for storing data and information in RDBMS. A table is a collection of related data entries and it consists of columns and rows.
View: A view is a virtual table whose contents are defined by a query. Unless indexed, a view does not exist as a stored set of data values in a database. Advantages over table are
That method was introduced in Commons Codec 1.4. This exception indicates that you've an older version of Commons Codec somewhere else in the webapp's runtime classpath which got precedence in classloading. Check all paths covered by the webapp's runtime classpath. This includes among others the Webapp/WEB-INF/lib
, YourAppServer/lib
, JRE/lib
and JRE/lib/ext
. Finally remove or upgrade the offending older version.
Update: as per the comments, you can't seem to locate it. I can only suggest to outcomment the code using that newer method and then put the following line in place:
System.out.println(Base64.class.getProtectionDomain().getCodeSource().getLocation());
That should print the absolute path to the JAR file where it was been loaded from during runtime.
Update 2: this did seem to point to the right file. Sorry, I can't explain your problem anymore right now. All I can suggest is to use a different Base64
method like encodeBase64(byte[])
and then just construct a new String(bytes)
yourself. Or you could drop that library and use a different Base64 encoder, for example this one.
using (SqlConnection conn = new SqlConnection("Server=(local);DataBase=Northwind;Integrated Security=SSPI")) {
conn.Open();
// 1. create a command object identifying the stored procedure
SqlCommand cmd = new SqlCommand("CustOrderHist", conn);
// 2. set the command object so it knows to execute a stored procedure
cmd.CommandType = CommandType.StoredProcedure;
// 3. add parameter to command, which will be passed to the stored procedure
cmd.Parameters.Add(new SqlParameter("@CustomerID", custId));
// execute the command
using (SqlDataReader rdr = cmd.ExecuteReader()) {
// iterate through results, printing each to console
while (rdr.Read())
{
Console.WriteLine("Product: {0,-35} Total: {1,2}",rdr["ProductName"],rdr["Total"]);
}
}
}

The error TypeError: 'numpy.ndarray' object is not callable
means that you tried to call a numpy array as a function. We can reproduce the error like so in the repl:
In [16]: import numpy as np
In [17]: np.array([1,2,3])()
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
/home/user/<ipython-input-17-1abf8f3c8162> in <module>()
----> 1 np.array([1,2,3])()
TypeError: 'numpy.ndarray' object is not callable
If we are to assume that the error is indeed coming from the snippet of code that you posted (something that you should check,) then you must have reassigned either pd.rolling_mean
or pd.rolling_std
to a numpy array earlier in your code.
What I mean is something like this:
In [1]: import numpy as np
In [2]: import pandas as pd
In [3]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Works
Out[3]: array([ nan, nan, nan])
In [4]: pd.rolling_mean = np.array([1,2,3])
In [5]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
/home/user/<ipython-input-5-f528129299b9> in <module>()
----> 1 pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...
TypeError: 'numpy.ndarray' object is not callable
So, basically you need to search the rest of your codebase for pd.rolling_mean = ...
and/or pd.rolling_std = ...
to see where you may have overwritten them.
reload(pd)
just before your snippet, which should make it run by restoring the value of pd
to what you originally imported it as, but I still highly recommend that you try to find where you may have reassigned the given functions.
You need to set Div2 to Div1's innerHTML. Also, JavaScript is case sensitive - in your HTML, the id Div2
is DIV2
. Also, you should use document
, not Document
:
var MyDiv1 = document.getElementById('DIV1');
var MyDiv2 = document.getElementById('DIV2');
MyDiv2.innerHTML = MyDiv1.innerHTML;

This should work:
$ mkdir -p dir
or:

elif [[ ! -d $dir ]]; then
echo "$dir already exists but is not a directory" 1>&2

which will create the directory if it doesn't exist, but warn you if the name of the directory you're trying to create is already in use by something other than a directory.

I know this thread is old but I just wanted to add this answer for those who believe it's safer to Alter
than Drop

. The below will Alter
the Function
if it exists or Create
it if doesn't:
IF NOT EXISTS (SELECT *
FROM sys.objects
WHERE object_id = OBJECT_ID(N'[dbo].[foo]')
AND type IN ( N'FN', N'IF', N'TF', N'FS', N'FT' ))
EXEC('CREATE FUNCTION [dbo].[foo]() RETURNS INT AS BEGIN RETURN 0 END')
GO
ALTER FUNCTION [dbo].[foo]
AS
...
I had the similar issue. I solved it the following way after a number of attempts to follow the pieces of advice in the forums. I am reposting the solution because it could be helpful for others.
I am running Windows 7 (Apache 2.2 & PHP 5.2.17 & MySQL 5.0.51a), the syntax in the file "httpd.conf" (C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd.conf) was sensitive to slashes. You can check if "php.ini" is read from the right directory. Just type in your browser "localhost/index.php". The code of index.php is the following:
<?php
echo phpinfo();
?>
There is the row (not far from the top) called "Loaded Configuration File". So, if there is nothing added, then the problem could be that your "php.ini" is not read, even you uncommented (extension=php_mysql.dll and extension=php_mysqli.dll). So, in order to make it work I did the following step. I needed to change from
PHPIniDir 'c:\PHP\'
to
PHPIniDir 'c:\PHP'
Pay the attention that the last slash disturbed everything!
Now the row "Loaded Configuration File" gets "C:\PHP\php.ini" after refreshing "localhost/index.php" (before I restarted Apache2.2) as well as mysql block is there. MySQL and PHP are working together!
Submit form when your checkbox is checked
$(document).ready(function () {
$("#yoursubmitbuttonid").click(function(){
if( $(".yourcheckboxclass").is(":checked") )
{
$("#yourformId").submit();
}else{
alert("Please select !!!");
return false;
}
return false;
});
});
The only thing that worked for me was to set Path=/
on the cookie.
Moreover, the default value of a path attribute seems to be different from browsers to browsers although I tested only two of them (Firefox and Chrome).
Chrome tries to set a cookie as is; if path
attribute is omitted in Set-Cookie
header then it will not be stored and ignored.
However, Firefox stores a cookie even without an explicit path
attribute. It just set it with the requested path; my request url was /api/v1/users
and the path was set to /api/v1
automatically.
Anyway, both browsers worked when path
was set to /
even without an explicit domain, ie Domain=localhost
or something. So there are some differences in the way how each browser handles cookies.
To run the functions in a DLL, first find out what those functions are using any PE (Portable Executable) analysis program (e.g. Dependency Walker). Then use RUNDLL32.EXE with this syntax:
RUNDLL32.EXE <dllname>,<entrypoint> <optional arguments>
dllname is the path and name of your dll file, entrypoint is the function name, and optional arguments are the function arguments

In my case it was enough to add this part to the pom.xml
file:
<build>
<plugins>

<version>3.8.0</version>
<configuration>
<release>11</release>
</configuration>

</plugins>
</build>
itertools
is ideally suited for this:
itertools.chain.from_iterable((''.join(l)
for l in itertools.product(charset, repeat=i))
for i in range(1, maxlen + 1))
The answer that dtsg gave works:
string filePath = ConfigurationManager.AppSettings["ClientsFilePath"];
BUT, you need to add an assembly reference to
System.Configuration
Go to your Solution Explorer and right click on References and select Add reference. Select the Assemblies tab and search for Configuration.
Here is an example of my App.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<appSettings>
<add key="AdminName" value="My Name"/>
<add key="AdminEMail" value="MyEMailAddress"/>
</appSettings>
</configuration>
Which you can get in the following way:
string adminName = ConfigurationManager.AppSettings["AdminName"];
have at look at the static methods DateTime.Parse()
and DateTime.TryParse()
. They will allow you to pass in your date string and a format string, and get a DateTime object in return.
this error occur when you change your php version: it's very simple to suppress this error message
To suppress the DEPRECATED Error message, just add below code into your index.php file:
init_set('display_errors',False);
I had a single page application on entering URL it was creating a HashMap (used by my webpage) which contained data from multiple databases. I did following things to load everything during server start time-
1- Created ContextListenerClass
public class MyAppContextListener implements ServletContextListener
@Autowired
private MyDataProviderBean myDataProviderBean;
public MyDataProviderBean getMyDataProviderBean() {
return MyDataProviderBean;
}
public void setMyDataProviderBean(MyDataProviderBean MyDataProviderBean) {
this.myDataProviderBean = MyDataProviderBean;
}
@Override
public void contextDestroyed(ServletContextEvent arg0) {
System.out.println("ServletContextListener destroyed");
}
@Override
public void contextInitialized(ServletContextEvent context) {
System.out.println("ServletContextListener started");
ServletContext sc = context.getServletContext();
WebApplicationContext springContext = WebApplicationContextUtils.getWebApplicationContext(sc);
MyDataProviderBean MyDataProviderBean = (MyDataProviderBean)springContext.getBean("myDataProviderBean");
Map<String, Object> myDataMap = MyDataProviderBean.getDataMap();
sc.setAttribute("myMap", myDataMap);
}
2- Added below entry in web.xml
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
<listener-class>com.context.listener.MyAppContextListener</listener-class>
</listener>
3- In my Controller Class updated code to first check for Map in servletContext
@RequestMapping(value = "/index", method = RequestMethod.GET)
public String index(@ModelAttribute("model") ModelMap model) {
Map<String, Object> myDataMap = new HashMap<String, Object>();
if (context != null && context.getAttribute("myMap")!=null)
{
myDataMap=(Map<String, Object>)context.getAttribute("myMap");
}
else
{
myDataMap = myDataProviderBean.getDataMap();
}
for (String key : myDataMap.keySet())
{
model.addAttribute(key, myDataMap.get(key));
}
return "myWebPage";
}
With this much change when I start my tomcat it loads dataMap during startTime and puts everything in servletContext which is then used by Controller Class to get results from already populated servletContext .
Try the following code:
//...
By mySelector = By.xpath("/html/body/div[1]/div/section/div/div[2]/form[1]/div/ul/li");
List<WebElement> myElements = driver.findElements(mySelector);
for(WebElement e : myElements) {
System.out.println(e.getText());
}
It will returns with the whole content of the <li>
tags, like:
<a class="extra">Vše</a> (950)</li>
But you can easily get the number now from it, for example by using split()
and/or substring()
.
I believe this is an easier way of knowing where your IIS logs are, rather than just assuming a default location:
Go to your IIS site, e.g. Default, click on it, and you should see "Logging" to the right if logging is enabled:
Open it and you should see the folder right there:
You are welcome!

You need grant privileges to the user if you want external acess to database(ie. web pages).
This approach is not correct beacuse of Google Server Overload. For more informations see https://gis.stackexchange.com/questions/15052/how-to-avoid-google-map-geocode-limit#answer-15365

});
latlng = results[0].geometry.location;
map.addMarker({

}
if(geocode_count == addresses.length) {
//set counter == 0 so it wont's stop next round

Another way is to take the first element of the reversed vector:
rev(dat$vect1$vec2)[1]
You can first choose which cells you don't want to be protected (to be user-editable) by setting the Locked status of them to False:
Worksheets("Sheet1").Range("B2:C3").Locked = False
Then, you can protect the sheet, and all the other cells will be protected. The code to do this, and still allow your VBA code to modify the cells is:
Worksheets("Sheet1").Protect UserInterfaceOnly:=True
or
Call Worksheets("Sheet1").Protect(UserInterfaceOnly:=True)
if ($('#A').attr('myattr')) {
// attribute exists
} else {
// attribute does not exist
}
EDIT:
The above will fall into the else
-branch when myattr
exists but is an empty string or "0". If that's a problem you should explicitly test on undefined
:
if ($('#A').attr('myattr') !== undefined) {
// attribute exists
} else {
// attribute does not exist
}

A late answer, but here is an alternative to the SCOPE_IDENTITY()
answers that we ended up using: OUTPUT INSERTED
Return only ID of inserted object:
It allows you to get all or some attributes of the inserted row:
string insertUserSql = @"INSERT INTO dbo.[User](Username, Phone, Email)
OUTPUT INSERTED.[Id]
VALUES(@Username, @Phone, @Email);";
int newUserId = conn.QuerySingle<int>(
insertUserSql,
new
{
Username = "lorem ipsum",
Phone = "555-123",
Email = "lorem ipsum"
},
tran);
Return inserted object with ID:
If you wanted you could get Phone
and Email
or even the whole inserted row:
string insertUserSql = @"INSERT INTO dbo.[User](Username, Phone, Email)
OUTPUT INSERTED.*
VALUES(@Username, @Phone, @Email);";
User newUser = conn.QuerySingle<User>(
insertUserSql,
new
{
Username = "lorem ipsum",
Phone = "555-123",
Email = "lorem ipsum"
},
tran);
Also, with this you can return data of deleted or updated rows. Just be careful if you are using triggers because (from link mentioned before):
Columns returned from OUTPUT reflect the data as it is after the INSERT, UPDATE, or DELETE statement has completed but before triggers are executed.
For INSTEAD OF triggers, the returned results are generated as if the INSERT, UPDATE, or DELETE had actually occurred, even if no modifications take place as the result of the trigger operation. If a statement that includes an OUTPUT clause is used inside the body of a trigger, table aliases must be used to reference the trigger inserted and deleted tables to avoid duplicating column references with the INSERTED and DELETED tables associated with OUTPUT.
More on it in the docs: link
Use the below command to copy data from CSV in a single line without casting and changing your datatype. Please replace "NULL" by your string which creating error in copy data

Don't use GridLayout for something it wasn't meant to do. It sounds to me like GridBagLayout would be a better fit for you, either that or MigLayout (though you'll have to download that first since it's not part of standard Java). Either that or combine layout managers such as BoxLayout for the lines and GridLayout to hold all the rows.
For example, using GridBagLayout:
import java.awt.*;
import javax.swing.*;
public class LayoutEg1 extends JPanel{
private static final int ROWS = 10;
public LayoutEg1() {
setLayout(new GridBagLayout());
for (int i = 0; i < ROWS; i++) {
GridBagConstraints gbc = makeGbc(0, i);
JLabel label = new JLabel("Row Label " + (i + 1));
add(label, gbc);
JPanel panel = new JPanel();
panel.add(new JCheckBox("check box"));
panel.add(new JTextField(10));
panel.add(new JButton("Button"));
panel.setBorder(BorderFactory.createEtchedBorder());
gbc = makeGbc(1, i);
add(panel, gbc);
}
}
private GridBagConstraints makeGbc(int x, int y) {
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridwidth = 1;
gbc.gridheight = 1;
gbc.gridx = x;
gbc.gridy = y;
gbc.weightx = x;
gbc.weighty = 1.0;
gbc.insets = new Insets(5, 5, 5, 5);
gbc.anchor = (x == 0) ? GridBagConstraints.LINE_START : GridBagConstraints.LINE_END;
gbc.fill = GridBagConstraints.HORIZONTAL;
return gbc;
}
private static void createAndShowUI() {
JFrame frame = new JFrame("Layout Eg1");

frame.setVisible(true);

From Oracle Wiki, error 02287 is
An ORA-02287 occurs when you use a sequence where it is not allowed.
Of the places where sequences can't be used, you seem to be trying:
In a sub-query
So it seems you can't do multiples in the same statement.
The solution they offer is:
If you want the sequence value to be inserted into the column for every row created, then create a before insert trigger and fetch the sequence value in the trigger and assign it to the column

. Returns ["a", "b"]
.
See: https://developer.chrome.com/devtools/docs/commandline-api#keysobject
Later edit: If you need to copy it quick (for bigger objects), do copy(keys(foo.prototype))
and you will have it in the clipboard.

For a Node.js app, in the server.js file before registering all of my own routes, I put the code below. It sets the headers for all responses. It also ends the response gracefully if it is a pre-flight "OPTIONS" call and immediately sends the pre-flight response back to the client without "nexting" (is that a word?) down through the actual business logic routes. Here is my server.js file. Relevant sections highlighted for Stackoverflow use.
// server.js
// ==================
// BASE SETUP
// import the packages we need
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var morgan = require('morgan');
var jwt = require('jsonwebtoken'); // used to create, sign, and verify tokens
// ====================================================
// configure app to use bodyParser()
// this will let us get the data from a POST
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
// Logger
app.use(morgan('dev'));
// -------------------------------------------------------------
// STACKOVERFLOW -- PAY ATTENTION TO THIS NEXT SECTION !!!!!
// -------------------------------------------------------------
//Set CORS header and intercept "OPTIONS" preflight call from AngularJS
var allowCrossDomain = function(req, res, next) {
res.header('Access-Control-Allow-Origin', '*');
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
res.header('Access-Control-Allow-Headers', 'Content-Type');
if (req.method === "OPTIONS")
res.send(200);
else
next();
}
// -------------------------------------------------------------
// STACKOVERFLOW -- END OF THIS SECTION, ONE MORE SECTION BELOW
// -------------------------------------------------------------
// =================================================
// ROUTES FOR OUR API
var route1 = require("./routes/route1");
var route2 = require("./routes/route2");
var error404 = require("./routes/error404");
// ======================================================
// REGISTER OUR ROUTES with app
// -------------------------------------------------------------
// STACKOVERFLOW -- PAY ATTENTION TO THIS NEXT SECTION !!!!!
// -------------------------------------------------------------
app.use(allowCrossDomain);
// -------------------------------------------------------------
// STACKOVERFLOW -- OK THAT IS THE LAST THING.
// -------------------------------------------------------------
app.use("/api/v1/route1/", route1);
app.use("/api/v1/route2/", route2);
app.use('/', error404);
// =================
// START THE SERVER
var port = process.env.PORT || 8080; // set our port

I did the following and was able to connect:
1) changed IIS express config binding from local host to '*'
binding protocol="http" bindingInformation="*:8888:*"
2) Defined inbound rule on firewall to allow the particular port for the protocol type: tcp
3) Add the following command to add network configuration for your port: netsh http add urlacl url=http://*:8888/ user=everyone
The way I am doing it when I am running php scripts is:
* * * * * php /path/to/php/script.php &
<?php
if (shell_exec('ps aux | grep ' . __FILE__ . ' | wc -l') > 1) {
exit('already running...');
}
// do stuff
This command is searching in the system process list for the current php filename if it exists the line counter (wc -l) will be greater then one because the search command itself containing the filename
so if you running php crons add the above code to the start of your php code and it will run only once.
Try this:
git config --global alias.all '!f() { find . -d -name ".git" | sed s/\\/\.git//g | xargs -P10 -I{} git --git-dir={}/.git --work-tree={} $1; }; f'
It runs ten threads in parallel and does what ever git command you want to all repos in the folder structure. No matter if the repo is one or n levels deep.
E.g: git all pull
$('.login').toggle(
function(){
$('#panel').animate({
height: "150",
padding:"20px 0",
backgroundColor:'#000000',
opacity:.8
}, 500);
$('#otherdiv').animate({
//otherdiv properties here
}, 500);
},
function(){
$('#panel').animate({
height: "0",
padding:"0px 0",
opacity:.2
}, 500);
$('#otherdiv').animate({
//otherdiv properties here
}, 500);
});
int i = (int) (10 +Math.random()*11);
this will give you random number between 10 to 20.
the key here is:
a + Math.random()*b
a starting num (10) and ending num is max number (20) - a (10) + 1 (11)
Enjoy!
In my case setting AppPool->AdvancedSettings->Maximum Worker Proccesses to 1 helped.
I assume you want the PDF to display in the browser, rather than forcing a download. If that is the case, try setting the Content-Disposition
header with a value of inline
.
Also remember that this will also be affected by browser settings - some browsers may be configured to always download PDF files or open them in a different application (e.g. Adobe Reader)
Just downloaded the latest mysqlworkbench which is compatible with the latest encryption:

Use 8.0.21 until these are fixed
if you want to send arguments and receive the result from second fragment, you may use Fragment.setArguments to accomplish this task
static class FirstFragment extends Fragment {
final Handler mUIHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case 101: // receive the result from SecondFragment
Object result = msg.obj;
// do something according to the result
break;
}
};
};
void onStartSecondFragments() {
Message msg = Message.obtain(mUIHandler, 101, 102, 103, new Object()); // replace Object with a Parcelable if you want to across Save/Restore
// instance
putParcelable(new SecondFragment(), msg).show(getFragmentManager().beginTransaction(), null);
}
}
static class SecondFragment extends DialogFragment {
Message mMsg; // arguments from the caller/FirstFragment
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onViewCreated(view, savedInstanceState);
mMsg = getParcelable(this);
}
void onClickOK() {
mMsg.obj = new Object(); // send the result to the caller/FirstFragment
mMsg.sendToTarget();
}
}
static <T extends Fragment> T putParcelable(T f, Parcelable arg) {
if (f.getArguments() == null) {
f.setArguments(new Bundle());
}
f.getArguments().putParcelable("extra_args", arg);
return f;
}
static <T extends Parcelable> T getParcelable(Fragment f) {
return f.getArguments().getParcelable("extra_args");
}
I tried with an alternate method:
Hit F12 key Then, at right hand side in the drop down menu, select internet explorer version 9.
That's it and it worked for me.
To remove an item from a text file, first move all the text to a list and remove whichever item you want. Then write the text stored in the list into a text file:
List<string> quotelist=File.ReadAllLines(filename).ToList();
string firstItem= quotelist[0];
quotelist.RemoveAt(0);
File.WriteAllLines(filename, quotelist.ToArray());
return firstItem;
To see which files are changed and view the actual code changes compared to the master
branch you could use:
git diff --stat --patch origin master
NOTE: If you happen to use any of the Intellij IDEs then you can right-click your top-level project, select Git > Compare with branch > and pick the origin you want e.g. origin/master
. In the file tree that will appear you can double-click the files to see a visual diff. Unlike the command-line option above you can edit your local versions from the diff window.
This should work nicely:
UPDATE tb_Company SET CompanyIndustry =
CONCAT(UPPER(LEFT(CompanyIndustry, 1)), SUBSTRING(CompanyIndustry, 2))
I have followed a different approach to solve pretty much the same problem, in my case, I made a new extension that adds PHP syntax highlighting support for Drupal-specific files (such as .module and .inc): https://github.com/mastazi/VS-code-drupal
As you can see in the code, I created a new extension rather than modifying the existing PHP extension. Obviously I declare a dependency on the PHP extension in the Drupal extension.
The advantage of doing it this way is that if there is an update to the PHP extension, my custom support for Drupal doesn't get lost in the update process.
Probably because you're using unsafe code.
Are you doing something with pointers or unmanaged assemblies somewhere?
As if you want your app to run in > 24 versions too, follow these:

3.for creating notifications (with images) use this method where you are handling notifications, if directly then add in the firebasemessaging service or if you are using some util class then add in that util class :

if (mChannel == null) {
mChannel = new NotificationChannel(id, title, importance);
mChannel.enableVibration(true);
mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
notificationManager.createNotificationChannel(mChannel);
}
builder = new NotificationCompat.Builder(mContext, id);
intent = new Intent(mContext, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);

.setPriority(Notification.PRIORITY_HIGH);
}
Notification notification = builder.build();
notificationManager.notify(NOTIFY_ID, notification);
}
Follow these steps and your notification will come in the notification tray.

I was trying to solve my issue with some of the answers above and for some reason it didn't work. I did switch to use the git extensions and this are the steps I did follow.
Tools -> Settings -> SSH -> Other ssh client
C:\Program Files\Git\usr\bin\ssh.exe
I guess that this steps are just the same explained above. The only difference is that I used the Git Extensions User Interface instead of the terminal. Hope this help.
cp dir1/* dir2
Or if you have directories inside dir1 that you'd want to copy as well
cp -r dir1/* dir2

But what I came to know after reading all these, we haven't observed that on which folder the struts.xml file or any configuration file which is necessary for the web application.
My SOULUTION IS:
Hope the problem solved.
You cannot do it. C compiler cannot do such a complex thing on stack.
You have to use heap and dynamic allocation.
What you really need to do:
Use *access(boardAux, x, y, size) = 42 to interact with the matrix.
I once wrote an unround tool, to find the minimal perturbation to a set of numbers to match a goal. It was a different problem, but one could in theory use a similar idea here. In this case, we have a set of choices.
Thus for the first element, we can either round it up to 14, or down to 13. The cost (in a binary integer programming sense) of doing so is less for the round up than the round down, because the round down requires we move that value a larger distance. Similarly, we can round each number up or down, so there are a total of 16 choices we must choose from.
13.626332
47.989636
9.596008
+ 28.788024
-----------
100.000000
I'd normally solve the general problem in MATLAB, here using bintprog, a binary integer programming tool, but there are only a few choices to be tested, so it is easy enough with simple loops to test out each of the 16 alternatives. For example, suppose we were to round this set as:
Original Rounded Absolute error
13.626 13 0.62633
47.99 48 0.01036
9.596 10 0.40399
+ 28.788 29 0.21198
---------------------------------------
100.000 100 1.25266
The total absolute error made is 1.25266. It can be reduced slightly by the following alternative rounding:
Original Rounded Absolute error
13.626 14 0.37367
47.99 48 0.01036
9.596 9 0.59601
+ 28.788 29 0.21198
---------------------------------------
100.000 100 1.19202
In fact, this will be the optimal solution in terms of the absolute error. Of course, if there were 20 terms, the search space will be of size 2^20 = 1048576. For 30 or 40 terms, that space will be of significant size. In that case, you would need to use a tool that can efficiently search the space, perhaps using a branch and bound scheme.
Check your windows-firewall feature in control panel. Outbound and inbound port should allow port 8089. (or write a new rule for this- Right hand side, actions - new rules.) it worked for me!
jQuery also has an excellent implementation that's incredibly easy to use. Here's how you could implement this functionality across browsers:
$(document).keypress(function(e){
var checkWebkitandIE=(e.which==26 ? 1 : 0);
var checkMoz=(e.which==122 && e.ctrlKey ? 1 : 0);
if (checkWebkitandIE || checkMoz) $("body").append("<p>ctrl+z detected!</p>");

Another way of doing this is to use the keydown event and track the event.keyCode. However, since jQuery normalizes keyCode and charCode using event.which, their spec recommends using event.which in a variety of situations:
$(document).keydown(function(e){
if (e.keyCode==90 && e.ctrlKey)
$("body").append("<p>ctrl+z detected!</p>");
});
i have tested a sample and i would like to share this sample and i am sure it's quite help full. I have done all thing in body, first creating an structure there on click of button you will call a function selectallelement(); on mouse click which will pass the id of that div about which you want to know the childrens. I have given alerts here on different level so u can test where r u now in the coding .
<body>
<h1>javascript to count the number of children of given child</h1>
<div id="count">
<span>a</span>
<span>s</span>
<span>d</span>
<span>ff</span>
<div>fsds</div>
<p>fffff</p>
</div>
<button type="button" onclick="selectallelement('count')">click</button>
<p>total element no.</p>
<p id="sho">here</p>
<script>
function selectallelement(divid)
{
alert(divid);
var ele = document.getElementById(divid).children;
var match = new Array();
var i = fillArray(ele,match);
alert(i);
document.getElementById('sho').innerHTML = i;
}
function fillArray(e1,a1)
{
alert("we are here");
for(var i =0;i<e1.length;i++)
{
if(e1[i].id.indexOf('count') == 0)
a1.push(e1[i]);
}
return i;
}
</script>
</body>
USE THIS I AM SURE U WILL GET YOUR ANSWER ...THANKS
Also something important to add here, in order to set default values for arrays and objects we must use the default function for props:
propE: {
type: Object,
// Object or array defaults must be returned from
// a factory function
default: function () {
return { message: 'hello' }
}
},
According to the pytest docs, pytest --capture=sys

android.provider.telephony.SMS_RECEIVED
is not correct because Telephony is a class and it should be capital as in android.provider.Telephony.SMS_RECEIVED
for me it worked something like this. has the improvement that only changes the text in SOME options, not in all.
First i take the names of the spinner and create the arrayadapter with a customize view, but it doesn't matter now, the key is override the getView, and inside change the values u need to change. In my case was only the first one, the rest i leave the original
public void rellenarSpinnerCompeticiones(){
spinnerArrayCompeticiones = new ArrayList<String>();
for(Competicion c: ((Controlador)getApplication()).getCompeticiones()){
spinnerArrayCompeticiones.add(c.getNombre());
}
//ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this,R.layout.spinner_item_competicion,spinnerArrayCompeticiones);
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this, R.layout.spinner_item_competicion, spinnerArrayCompeticiones){
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View v = vi.inflate(R.layout.spinner_item_competicion, null);
final TextView t = (TextView)v.findViewById(R.id.tvCompeticion);
if(spinnerCompeticion.getSelectedItemPosition()>0){
t.setText(spinnerArrayCompeticiones.get(spinnerCompeticion.getSelectedItemPosition()));
}else{
t.setText("Competiciones");
}
return v;
}
};
spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinnerCompeticion.setAdapter(spinnerArrayAdapter);
}
Another interesting solution to luch an exeternal application with a WinForm container is the follow:
[DllImport("user32.dll")]
static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
private void Form1_Load(object sender, EventArgs e)
{
ProcessStartInfo psi = new ProcessStartInfo("notepad.exe");
psi.WindowStyle = ProcessWindowStyle.Minimized;
Process p = Process.Start(psi);
Thread.Sleep(500);
SetParent(p.MainWindowHandle, panel1.Handle);
CenterToScreen();
psi.WindowStyle = ProcessWindowStyle.Normal;
}
The step to ProcessWindowStyle.Minimized
from ProcessWindowStyle.Normal remove the annoying delay.

The shortcut to comment out or uncomment the selected text or current line:
Alternatively, use the menu: Edit > Comment
For the block comment you may want to use:
dplyr
packageIf the function that you want to apply is vectorized,
then you could use the mutate
function from the dplyr
package:
> library(dplyr)
> myf <- function(tens, ones) { 10 * tens + ones }
> x <- data.frame(hundreds = 7:9, tens = 1:3, ones = 4:6)
> mutate(x, value = myf(tens, ones))
hundreds tens ones value
1 7 1 4 14
2 8 2 5 25
3 9 3 6 36
plyr
packageIn my humble opinion,
the tool best suited to the task is mdply
from the plyr
package.
Example:
> library(plyr)
> x <- data.frame(tens = 1:3, ones = 4:6)
> mdply(x, function(tens, ones) { 10 * tens + ones })
tens ones V1
1 1 4 14
2 2 5 25
3 3 6 36
Unfortunately, as Bertjan Broeksema pointed out,
this approach fails if you don't use all the columns of the data frame
in the mdply
call.
For example,
> library(plyr)
> x <- data.frame(hundreds = 7:9, tens = 1:3, ones = 4:6)
> mdply(x, function(tens, ones) { 10 * tens + ones })
Error in (function (tens, ones) : unused argument (hundreds = 7)
You can simply use cells.select
to select all cells in the worksheet. You can get a valid address by saying Range(Cells.Address)
.
If you want to find the last Used Range
where you have made some formatting change or entered a value in you can call ActiveSheet.UsedRange
and select it from there. Hope that helps
Here's what I'm using:
$('input.date').datepicker({
beforeShow: function(input, inst) {
inst.dpDiv.css({
marginTop: -input.offsetHeight + 'px',
marginLeft: input.offsetWidth + 'px'
});
}
});
You may also want to add a bit more to the left margin so it's not right up against the input field.
Please note that the problem is not white
color. It is because it is being transparent.
When an element is made transparent, all of its child element's opacity; alpha filter in IE 6 7 etc, is changed to the new value.
So you cannot say that it is white!
You can place an element above it, and change that element's transparency to 1
while changing the image's transparency to .2
or what so ever you want to.
just follow below steps:

Debug.Print
outputs to the "Immediate" window.
Also, you can simply type ?
and then a statement directly into the immediate window (and then press Enter) and have the output appear right below, like this:
This can be very handy to quickly output the property of an object...
? myWidget.name
...to set the property of an object...
myWidget.name = "thingy"
...or to even execute a function or line of code, while in debugging mode:
Sheet1.MyFunction()
Try adding these options to socket.io:
const options = { transports: ['websocket'], pingTimeout: 3000, pingInterval: 5000 };
I hope this will help you !
Just make use of JavaScript promises. Put the then
method after swal
function. We do not need to use timer features.
For example:
swal({
title: "Wow!",
text: "Message!",
type: "success"
}).then(function() {
window.location = "redirectURL";
});
The promise method .then
is used to wait until the user reads the information of modal window and decide which decision to make by clicking in one button. For example, Yes
or No
.
After the click, the Sweet Alert could redirect the user to another screen, call another Sweet Alert modal window with contains new and subsequent question, go to a external link, etc.
Again, we do not have to use timer because it is much better to control user action. The user could wait for the eternity or take action as a Thanos' or Iron Man's finger snap.
With the use of promises, the code becomes shorter, clean and elegant.
I had a similar issue and I just took the background image with photoshop and created a new .png with the opacity I needed. Problem solved without worrying about if my CSS worked accross all devices & browsers
Its all metadata for the Foobar
module.
The first one is the docstring
of the module, that is already explained in Peter's answer.
How do I organize my modules (source files)? (Archive)
The first line of each file shoud be
#!/usr/bin/env python
. This makes it possible to run the file as a script invoking the interpreter implicitly, e.g. in a CGI context.Next should be the docstring with a description. If the description is long, the first line should be a short summary that makes sense on its own, separated from the rest by a newline.
All code, including import statements, should follow the docstring. Otherwise, the docstring will not be recognized by the interpreter, and you will not have access to it in interactive sessions (i.e. through
obj.__doc__
) or when generating documentation with automated tools.Import built-in modules first, followed by third-party modules, followed by any changes to the path and your own modules. Especially, additions to the path and names of your modules are likely to change rapidly: keeping them in one place makes them easier to find.
Next should be authorship information. This information should follow this format:
__author__ = "Rob Knight, Gavin Huttley, and Peter Maxwell" __copyright__ = "Copyright 2007, The Cogent Project" __credits__ = ["Rob Knight", "Peter Maxwell", "Gavin Huttley", "Matthew Wakefield"] __license__ = "GPL" __version__ = "1.0.1" __maintainer__ = "Rob Knight" __email__ = "[email protected]" __status__ = "Production"
Status should typically be one of "Prototype", "Development", or "Production".
__maintainer__
should be the person who will fix bugs and make improvements if imported.__credits__
differs from__author__
in that__credits__
includes people who reported bug fixes, made suggestions, etc. but did not actually write the code.
Here you have more information, listing __author__
, __authors__
, __contact__
, __copyright__
, __license__
, __deprecated__
, __date__
and __version__
as recognized metadata.

Have a look at Select2 for Bootstrap. It should be able to do everything you need.
Another good option is Selectize.js. It feels a bit more native to Bootstrap.
The site you linked uses a combination of CSS tricks to pull this off. First, it uses a background-image for the <input>
element. Then, in order to push the cursor over, it uses padding-left
.
In other words, they have these two CSS rules:
background: url(images/comment-author.gif) no-repeat scroll 7px 7px;
padding-left:30px;
Surely you just need:
double seconds = milliseconds / 1000.0;
There's no need to manually do the two parts separately - you just need floating point arithmetic, which the use of 1000.0
(as a double
literal) forces. (I'm assuming your milliseconds
value is an integer of some form.)
Note that as usual with double
, you may not be able to represent the result exactly. Consider using BigDecimal
if you want to represent 100ms as 0.1 seconds exactly. (Given that it's a physical quantity, and the 100ms wouldn't be exact in the first place, a double
is probably appropriate, but...)
Yes you understood it correctly, the function password_hash() will generate a salt on its own, and includes it in the resulting hash-value. Storing the salt in the database is absolutely correct, it does its job even if known.
// Hash a new password for storing in the database.
// The function automatically generates a cryptographically safe salt.
$hashToStoreInDb = password_hash($_POST['password'], PASSWORD_DEFAULT);
// Check if the hash of the entered login password, matches the stored hash.
// The salt and the cost factor will be extracted from $existingHashFromDb.
$isPasswordCorrect = password_verify($_POST['password'], $existingHashFromDb);
The second salt you mentioned (the one stored in a file), is actually a pepper or a server side key. If you add it before hashing (like the salt), then you add a pepper. There is a better way though, you could first calculate the hash, and afterwards encrypt (two-way) the hash with a server-side key. This gives you the possibility to change the key when necessary.
In contrast to the salt, this key should be kept secret. People often mix it up and try to hide the salt, but it is better to let the salt do its job and add the secret with a key.
Maybe check for any thing that you have changed under the php.ini file. For example I changed the ";intl.default_locale =" to ";intl.default_locale = en_utf8" in order to enable the "Internationalization extension (Intl)" without adding the "extension=php_intl.dll" then this same error occurred. So I suggest to check for similar mistakes.
You can use the fingerprintJS2 library, it helps a lot with calculating a browser fingerprint.

First you will have a config file in /etc/mongodb.conf
, therefore this sounds like a homebrew install which will use some more standardized paths. The whole /data/db/
thing is referenced in a lot of manual install documentation.
So basically from your log the server is not running, it's shutting down, so there is nothing for the shell to connect to. Seems like you have had some unclean shutdowns/restarts which has led to the inconsistency.
Clear the files in the journal /usr/local/var/mongodb/journal/
on your config.
Also:
sudo rm /var/lib/mongodb/mongod.lock
Just in case, even though that part looks clean. And then restart.
If you get the object after creation (for instance after "seasonal_decompose"), you can always access and edit the properties of the plot; for instance, changing the color of the first subplot from blue to black:
plt.axes[0].get_lines()[0].set_color('black')
I want to say something about the "G" status,
G: Changes on the repo were automatically merged into the working copy
I think the above definition is not cleary, it can generate a little confusion, because all files are automatically merged in to working copy, the correct one should be:
U = item (U)pdated to repository version
G = item’s local changes mer(G)ed with repository
C = item’s local changes (C)onflicted with repository
D = item (D)eleted from working copy
A = item (A)dded to working copy
The most straightforward method is to use plt.tight_layout
transformation which is actually more preferable as it doesn't do unnecessary cropping when using plt.savefig
import matplotlib as plt
plt.plot([1,2,3], [1,2,3])
plt.tight_layout(pad=0)
plt.savefig('plot.png')
However, this may not be preferable for complex plots that modifies the figure. Refer to Johannes S's answer that uses plt.subplots_adjust
if that's the case.
I had a similar situation, and after fruitless Googles, I declared a public string, which mods a string value of the debug / release path to get the project path. A benefit of using this method is that since it uses the currect project's directory, it matters not if you are working from a debug directory or a release directory:
public string DirProject()
{
string DirDebug = System.IO.Directory.GetCurrentDirectory();
string DirProject = DirDebug;
for (int counter_slash = 0; counter_slash < 4; counter_slash++)
{
DirProject = DirProject.Substring(0, DirProject.LastIndexOf(@"\"));
}
return DirProject;
}
You would then be able to call it whenever you want, using only one line:
string MyProjectDir = DirProject();
This should work in most cases.
In PowerShell, the "sc" command is an alias for the Set-Content cmdlet. You can workaround this using the following syntax:
sc.exe config Service obj= user password= pass
Specyfying the .exe extension, PowerShell bypasses the alias lookup.

Since the print today
returns what you want this means that the today object's __str__
function returns the string you are looking for.
So you can do mylist.append(today.__str__())
as well.

When using NOT IN you should ensure that none of the values are NULL:
SELECT mac, creation_date
FROM logs
WHERE logs_type_id=11
AND mac NOT IN (
SELECT mac
FROM consols
WHERE mac IS NOT NULL -- add this
)
To access a variable in a class, you must use $this->myVar
instead of $this->$myvar
.
And, you should use access identifier to declare a variable instead of var
.

.Net Core does not require mono in the sense of the mono framework. .Net Core is a framework that will work on multiple platforms including Linux. Reference https://dotnet.github.io/.
However the .Net core can use the mono framework. Reference https://docs.asp.net/en/1.0.0-rc1/getting-started/choosing-the-right-dotnet.html (note rc1 documentatiopn no rc2 available), however mono is not a Microsoft supported framework and would recommend using a supported framework
Now entity framework 7 is now called Entity Framework Core
and is available on multiple platforms including Linux. Reference https://github.com/aspnet/EntityFramework (review the road map)
I am currently using both of these frameworks however you must understand that it is still in release candidate stage (RC2
is the current version) and over the beta & release candidates there have been massive changes that usually end up with you scratching your head.
Here is a tutorial on how to install MVC .Net Core into Linux. https://docs.asp.net/en/1.0.0-rc1/getting-started/installing-on-linux.html
Finally you have a choice of Web Servers (where I am assuming the fast cgi
reference came from) to host your application on Linux. Here is a reference point for installing to a Linux enviroment. https://docs.asp.net/en/1.0.0-rc1/publishing/linuxproduction.html
I realise this post ends up being mostly links to documentation but at this point those are your best sources of information. .Net core is still relatively new in the .Net community and until its fully released I would be hesitant to use it in a product environment given the breaking changes between released version.
Since JsonSerializer is deprecated in .Net 4.0+ I used http://www.newtonsoft.com/json to solve this issue.

Native tooltip cannot be styled.
That being said, you can use some library that would show styles floating layers when element is being hovered (instead of the native tooltips, and suppress them) requiring little or no code modifications...
Splitting an empty string with String.split() returns a single element array containing an empty string. In most cases you'd probably prefer to get an empty array, or a null if you passed in a null, which is exactly what you get with org.apache.commons.lang3.StringUtils.split(str).
import org.apache.commons.lang3.StringUtils;
StringUtils.split(null) => null
StringUtils.split("") => []
StringUtils.split("abc def") => ["abc", "def"]
StringUtils.split("abc def") => ["abc", "def"]
StringUtils.split(" abc ") => ["abc"]
Another option is google guava Splitter.split() and Splitter.splitToList() which return an iterator and a list correspondingly. Unlike the apache version Splitter will throw an NPE on null
:
import com.google.common.base.Splitter;
Splitter SPLITTER = Splitter.on(',').trimResults().omitEmptyStrings();
SPLITTER.split("a,b, c , , ,, ") => [a, b, c]
SPLITTER.split("") => []
SPLITTER.split(" ") => []
SPLITTER.split(null) => NullPointerException
If you want a list rather than an iterator then use Splitter.splitToList().
Link function only gets called once, so it would not directly do what you are expecting. You need to use angular $watch
to watch a model variable.
This watch needs to be setup in the link function.
If you use isolated scope for directive then the scope would be
scope :{typeId:'@' }
In your link function then you add a watch like
link: function(scope, element, attrs) {
scope.$watch("typeId",function(newValue,oldValue) {
//This gets called when data changes.
});
}
If you are not using isolated scope use watch on some_prop
Your data may not be what you expect -- it seems you're expecting, but not getting, floats.
A simple solution to figuring out where this occurs would be to add a try/except to the for-loop:
for i in range(0,N):
w=f[i].split()
l1=w[1:8]
l2=w[8:15]
try:
list1=[float(x) for x in l1]
list2=[float(x) for x in l2]
except ValueError, e:
# report the error in some way that is helpful -- maybe print out i
result=stats.ttest_ind(list1,list2)
print result[1]
Data Storage:
Specify the utf8mb4
character set on all tables and text columns in your database. This makes MySQL physically store and retrieve values encoded natively in UTF-8. Note that MySQL will implicitly use utf8mb4
encoding if a utf8mb4_*
collation is specified (without any explicit character set).
In older versions of MySQL (< 5.5.3), you'll unfortunately be forced to use simply utf8
, which only supports a subset of Unicode characters. I wish I were kidding.
Data Access:
In your application code (e.g. PHP), in whatever DB access method you use, you'll need to set the connection charset to utf8mb4
. This way, MySQL does no conversion from its native UTF-8 when it hands data off to your application and vice versa.
Some drivers provide their own mechanism for configuring the connection character set, which both updates its own internal state and informs MySQL of the encoding to be used on the connection—this is usually the preferred approach. In PHP:
If you're using the PDO abstraction layer with PHP = 5.3.6, you can specify charset
in the DSN:
$dbh = new PDO('mysql:charset=utf8mb4');
If you're using mysqli, you can call set_charset()
:
$mysqli->set_charset('utf8mb4'); // object oriented style
mysqli_set_charset($link, 'utf8mb4'); // procedural style
If you're stuck with plain mysql but happen to be running PHP = 5.2.3, you can call mysql_set_charset
.
If the driver does not provide its own mechanism for setting the connection character set, you may have to issue a query to tell MySQL how your application expects data on the connection to be encoded: SET NAMES 'utf8mb4'
.
The same consideration regarding utf8mb4
/utf8
applies as above.
Output:
If your application transmits text to other systems, they will also need to be informed of the character encoding. With web applications, the browser must be informed of the encoding in which data is sent (through HTTP response headers or HTML metadata).
In PHP, you can use the default_charset
php.ini option, or manually issue the Content-Type
MIME header yourself, which is just more work but has the same effect.
When encoding the output using json_encode()
, add JSON_UNESCAPED_UNICODE
as a second parameter.
Input:
Unfortunately, you should verify every received string as being valid UTF-8 before you try to store it or use it anywhere. PHP's mb_check_encoding()
does the trick, but you have to use it religiously. There's really no way around this, as malicious clients can submit data in whatever encoding they want, and I haven't found a trick to get PHP to do this for you reliably.
From my reading of the current HTML spec, the following sub-bullets are not necessary or even valid anymore for modern HTML. My understanding is that browsers will work with and submit data in the character set specified for the document. However, if you're targeting older versions of HTML (XHTML, HTML4, etc.), these points may still be useful:
accept-charset
attribute to all your <form>
tags: <form ... accept-charset="UTF-8">
.<form>
tag.Other Code Considerations:
Obviously enough, all files you'll be serving (PHP, HTML, JavaScript, etc.) should be encoded in valid UTF-8.
You need to make sure that every time you process a UTF-8 string, you do so safely. This is, unfortunately, the hard part. You'll probably want to make extensive use of PHP's mbstring
extension.
PHP's built-in string operations are not by default UTF-8 safe. There are some things you can safely do with normal PHP string operations (like concatenation), but for most things you should use the equivalent mbstring
function.
To know what you're doing (read: not mess it up), you really need to know UTF-8 and how it works on the lowest possible level. Check out any of the links from utf8.com for some good resources to learn everything you need to know.
I would suggest following design :
Item Table:
Itemid, taglist1, taglist2
this will be fast and make easy saving and retrieving the data at item level.
In parallel build another table: Tags tag do not make tag unique identifier and if you run out of space in 2nd column which contains lets say 100 items create another row.
Now while searching for items for a tag it will be super fast.
I had to set both HighlightBrushKey and ControlBrushKey to get it to be correctly styled. Otherwise, whilst it has focus this will correctly use the transparent HighlightBrusKey. Bt, if the control loses focus (whilst it is still highlighted) then it uses the ControlBrushKey.
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
<SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" />
</Style.Resources>
When Using .Net 4.5 and above, use InactiveSelectionHighlightBrushKey
instead of ControlBrushKey
:
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
<SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="Transparent" />
</Style.Resources>
Hope this helps someone out.
To me the problem what that I had to check the box "Import maven projects automatically" under Setting> Maven>Importing
This is typically done manually by choosing the appropriate bits from the vector and then appending 0s.
For example, to shift a vector 8 bits
variable tmp : std_logic_vector(15 downto 0)
...
tmp := x"00" & tmp(15 downto 8);
Hopefully this simple answer is useful to someone
A join of two tables is best done by a DBMS, so it should be done that way. You could mirror the smaller table or subset of it on one of the databases and then join them. One might get tempted of doing this on an ETL server like informatica but I guess its not advisable if the tables are huge.
The max length of a varchar is subject to the max row size in MySQL, which is 64KB (not counting BLOBs):
VARCHAR(65535)
However, note that the limit is lower if you use a multi-byte character set:
VARCHAR(21844) CHARACTER SET utf8
Here are some examples:
The maximum row size is 65535, but a varchar also includes a byte or two to encode the length of a given string. So you actually can't declare a varchar of the maximum row size, even if it's the only column in the table.
mysql> CREATE TABLE foo ( v VARCHAR(65534) );
ERROR 1118 (42000): Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs
But if we try decreasing lengths, we find the greatest length that works:
mysql> CREATE TABLE foo ( v VARCHAR(65532) );
Query OK, 0 rows affected (0.01 sec)
Now if we try to use a multibyte charset at the table level, we find that it counts each character as multiple bytes. UTF8 strings don't necessarily use multiple bytes per string, but MySQL can't assume you'll restrict all your future inserts to single-byte characters.
mysql> CREATE TABLE foo ( v VARCHAR(65532) ) CHARSET=utf8;
ERROR 1074 (42000): Column length too big for column 'v' (max = 21845); use BLOB or TEXT instead
In spite of what the last error told us, InnoDB still doesn't like a length of 21845.
mysql> CREATE TABLE foo ( v VARCHAR(21845) ) CHARSET=utf8;
ERROR 1118 (42000): Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs
This makes perfect sense, if you calculate that 21845*3 = 65535, which wouldn't have worked anyway. Whereas 21844*3 = 65532, which does work.
mysql> CREATE TABLE foo ( v VARCHAR(21844) ) CHARSET=utf8;
Query OK, 0 rows affected (0.32 sec)
Just replace session_start with this.
if (!session_id() && !headers_sent()) {
session_start();
}
You can put it anywhere, even at the end :) Works fine for me. $_SESSION is accessible as well.
Here is an example that sorts by the header. This table is dynamic and changes with the JSON size.
I was able to build a dynamic table off of some other people's examples and documentation. http://jsfiddle.net/lastlink/v7pszemn/1/
<tr>
<th class="{{header}}" ng-repeat="(header, value) in items[0]" ng-click="changeSorting(header)">
{{header}}
<i ng-class="selectedCls2(header)"></i>
</tr>
<tbody>
<tr ng-repeat="row in pagedItems[currentPage] | orderBy:sort.sortingOrder:sort.reverse">
<td ng-repeat="cell in row">
{{cell}}
</td>
</tr>
Although the columns are out of order, on my .NET project they are in order.
You can make a custom border using a span. Make a span with a class (Specifying the direction in which the border is going) and an id:
<html>
<body>
<div class="mdiv">
<span class="VerticalBorder" id="Span1"></span>
<header class="mheader">
<span class="HorizontalBorder" id="Span2"></span>
</header>
</div>
</body>
</html>
Then, go to you CSS and set the class to position:absolute
, height:100%
(For Vertical Borders), width:100%
(For Horizontal Borders), margin:0%
and background-color:#000000;
. Add everthing else that is necessary:
body{
margin:0%;
}
div.mdiv{
position:absolute;
width:100%;
height:100%;
top:0%;
left:0%;
margin:0%;
}
header.mheader{
position:absolute;
width:100%;
height:20%; /* You can set this to whatever. I will use 20 for easier calculations. You don't need a header. I'm using it to show you the difference. */
top:0%;
left:0%;
margin:0%;
}
span.HorizontalBorder{
position:absolute;
width:100%;
margin:0%;
background-color:#000000;
}
span.VerticalBorder{
position:absolute;
height:100%;
margin:0%;
background-color:#000000;
}
Then set the id that corresponds to class="VerticalBorder"
to top:0%;
, left:0%;
, width:1%;
(Since the width of the mdiv is equal to the width of the mheader at 100%, the width will be 100% of what you set it. If you set the width to 1% the border will be 1% of the window's width). Set the id that corresponds to the class="HorizontalBorder"
to top:99%
(Since it's in a header container the top refers to the position it is in according to the header. This + the height should add up to 100% if you want it to reach the bottom), left:0%;
and height:1%
(Since the height of the mdiv is 5 times greater than the mheader height [100% = 100, 20% = 20, 100/20 = 5], the height will be 20% of what you set it. If you set the height to 1% the border will be .2% of the window's height). Here is how it will look:
span#Span1{
top:0%;
left:0%;
width:.4%;
}
span#Span2{
top:99%;
left:0%;
width:1%;
}
DISCLAIMER: If you resize the window to a small enough size, the borders will disappear. A solution would be to cap of the size of the border if the window is resized to a certain point. Here is what I did:
window.addEventListener("load", Loaded);
function Loaded() {
window.addEventListener("resize", Resized);
function Resized() {
var WindowWidth = window.innerWidth;
var WindowHeight = window.innerHeight;
var Span1 = document.getElementById("Span1");
var Span2 = document.getElementById("Span2");
if (WindowWidth <= 800) {
Span1.style.width = .4;
}
if (WindowHeight <= 600) {
Span2.style.height = 1;
}
}
}
If you did everything right, it should look like how it is in this link: https://jsfiddle.net/umhgkvq8/12/ For some odd reason, the the border will disappear in jsfiddle but not if you launch it to a browser.
Versioning of assemblies in .NET can be a confusing prospect given that there are currently at least three ways to specify a version for your assembly.
Here are the three main version-related assembly attributes:
// Assembly mscorlib, Version 2.0.0.0
[assembly: AssemblyFileVersion("2.0.50727.3521")]
[assembly: AssemblyInformationalVersion("2.0.50727.3521")]
[assembly: AssemblyVersion("2.0.0.0")]
By convention, the four parts of the version are referred to as the Major Version, Minor Version, Build, and Revision.
AssemblyFileVersion
is intended to uniquely identify a build of the individual assemblyTypically you’ll manually set the Major and Minor AssemblyFileVersion to reflect the version of the assembly, then increment the Build and/or Revision every time your build system compiles the assembly. The AssemblyFileVersion should allow you to uniquely identify a build of the assembly, so that you can use it as a starting point for debugging any problems.
On my current project we have the build server encode the changelist number from our source control repository into the Build and Revision parts of the AssemblyFileVersion. This allows us to map directly from an assembly to its source code, for any assembly generated by the build server (without having to use labels or branches in source control, or manually keeping any records of released versions).
This version number is stored in the Win32 version resource and can be seen when viewing the Windows Explorer property pages for the assembly.
The CLR does not care about nor examine the AssemblyFileVersion.
AssemblyInformationalVersion
is intended to represent the version of your entire productThe AssemblyInformationalVersion is intended to allow coherent versioning of the entire product, which may consist of many assemblies that are independently versioned, perhaps with differing versioning policies, and potentially developed by disparate teams.
“For example, version 2.0 of a product might contain several assemblies; one of these assemblies is marked as version 1.0 since it’s a new assembly that didn’t ship in version 1.0 of the same product. Typically, you set the major and minor parts of this version number to represent the public version of your product. Then you increment the build and revision parts each time you package a complete product with all its assemblies.” — Jeffrey Richter, [CLR via C# (Second Edition)] p. 57
The CLR does not care about nor examine the AssemblyInformationalVersion.
AssemblyVersion
is the only version the CLR cares about (but it cares about the entire AssemblyVersion
)The AssemblyVersion is used by the CLR to bind to strongly named assemblies. It is stored in the AssemblyDef manifest metadata table of the built assembly, and in the AssemblyRef table of any assembly that references it.
This is very important, because it means that when you reference a strongly named assembly, you are tightly bound to a specific AssemblyVersion of that assembly. The entire AssemblyVersion must be an exact match for the binding to succeed. For example, if you reference version 1.0.0.0 of a strongly named assembly at build-time, but only version 1.0.0.1 of that assembly is available at runtime, binding will fail! (You will then have to work around this using Assembly Binding Redirection.)
AssemblyVersion
has to match. (Yes, it does.)There is a little confusion around whether the entire AssemblyVersion has to be an exact match in order for an assembly to be loaded. Some people are under the false belief that only the Major and Minor parts of the AssemblyVersion have to match in order for binding to succeed. This is a sensible assumption, however it is ultimately incorrect (as of .NET 3.5), and it’s trivial to verify this for your version of the CLR. Just execute this sample code.
On my machine the second assembly load fails, and the last two lines of the fusion log make it perfectly clear why:

I think the source of this confusion is probably because Microsoft originally intended to be a little more lenient on this strict matching of the full AssemblyVersion, by matching only on the Major and Minor version parts:
“When loading an assembly, the CLR will automatically find the latest installed servicing version that matches the major/minor version of the assembly being requested.” — Jeffrey Richter, [CLR via C# (Second Edition)] p. 56
This was the behaviour in Beta 1 of the 1.0 CLR, however this feature was removed before the 1.0 release, and hasn’t managed to re-surface in .NET 2.0:
“Note: I have just described how you should think of version numbers. Unfortunately, the CLR doesn’t treat version numbers this way. [In .NET 2.0], the CLR treats a version number as an opaque value, and if an assembly depends on version 1.2.3.4 of another assembly, the CLR tries to load version 1.2.3.4 only (unless a binding redirection is in place). However, Microsoft has plans to change the CLR’s loader in a future version so that it loads the latest build/revision for a given major/minor version of an assembly. For example, on a future version of the CLR, if the loader is trying to find version 1.2.3.4 of an assembly and version 1.2.5.0 exists, the loader with automatically pick up the latest servicing version. This will be a very welcome change to the CLR’s loader — I for one can’t wait.” — Jeffrey Richter, [CLR via C# (Second Edition)] p. 164 (Emphasis mine)
As this change still hasn’t been implemented, I think it’s safe to assume that Microsoft had back-tracked on this intent, and it is perhaps too late to change this now. I tried to search around the web to find out what happened with these plans, but I couldn’t find any answers. I still wanted to get to the bottom of it.
So I emailed Jeff Richter and asked him directly — I figured if anyone knew what happened, it would be him.
He replied within 12 hours, on a Saturday morning no less, and clarified that the .NET 1.0 Beta 1 loader did implement this ‘automatic roll-forward’ mechanism of picking up the latest available Build and Revision of an assembly, but this behaviour was reverted before .NET 1.0 shipped. It was later intended to revive this but it didn’t make it in before the CLR 2.0 shipped. Then came Silverlight, which took priority for the CLR team, so this functionality got delayed further. In the meantime, most of the people who were around in the days of CLR 1.0 Beta 1 have since moved on, so it’s unlikely that this will see the light of day, despite all the hard work that had already been put into it.
The current behaviour, it seems, is here to stay.
It is also worth noting from my discussion with Jeff that AssemblyFileVersion was only added after the removal of the ‘automatic roll-forward’ mechanism — because after 1.0 Beta 1, any change to the AssemblyVersion was a breaking change for your customers, there was then nowhere to safely store your build number. AssemblyFileVersion is that safe haven, since it’s never automatically examined by the CLR. Maybe it’s clearer that way, having two separate version numbers, with separate meanings, rather than trying to make that separation between the Major/Minor (breaking) and the Build/Revision (non-breaking) parts of the AssemblyVersion.
AssemblyVersion
The moral is that if you’re shipping assemblies that other developers are going to be referencing, you need to be extremely careful about when you do (and don’t) change the AssemblyVersion of those assemblies. Any changes to the AssemblyVersion will mean that application developers will either have to re-compile against the new version (to update those AssemblyRef entries) or use assembly binding redirects to manually override the binding.
Just take another look at the version attributes on mscorlib:
// Assembly mscorlib, Version 2.0.0.0
[assembly: AssemblyFileVersion("2.0.50727.3521")]
[assembly: AssemblyInformationalVersion("2.0.50727.3521")]
[assembly: AssemblyVersion("2.0.0.0")]
Note that it’s the AssemblyFileVersion that contains all the interesting servicing information (it’s the Revision part of this version that tells you what Service Pack you’re on), meanwhile the AssemblyVersion is fixed at a boring old 2.0.0.0. Any change to the AssemblyVersion would force every .NET application referencing mscorlib.dll to re-compile against the new version!
PHP is run on a server, Your browser is a client. Once the server sends all the info to the client, nothing can be done on the server until another request is made.
To make another request without refreshing the page you are going to have to look into ajax. Look into jQuery as it makes ajax requests easy
There is also the rather spiffy FileStream
, introduced in SQL Server 2008.
If you're starting with a DOM element, check for a __vue__
property on that element. Any Vue View Models (components, VMs created by v-repeat
usage) will have this property.
You can use the "Inspect Element" feature in your browsers developer console (at least in Firefox and Chrome) to view the DOM properties.
Hope that helps!

This is what the official Anaconda documentation recommends:
conda update conda
conda update anaconda=2020.07
If the second line throws an error (typo in the documentation?) this worked here:
conda install anaconda=2020.07
(You can find all version specifier here.)
The command will update to a specific release of the Anaconda meta-package.
This is, IMHO, what 95% of Anaconda users want. Simply upgrading to the latest version of the Anaconda meta-package (put together and tested by the Anaconda Distributors) and not caring about the update status of individual packages (which would be issued by conda update --all
).

I like Ibu's one but, I think I have a better solution using his idea.
//Fade In.
element.style.opacity = 0;
var Op1 = 0;
var Op2 = 1;
var foo1, foo2;
foo1 = setInterval(Timer1, 20);
function Timer1()
{
element.style.opacity = Op1;
Op1 = Op1 + .01;
console.log(Op1); //Option, but I recommend it for testing purposes.
if (Op1 > 1)
{
clearInterval(foo1);
foo2 = setInterval(Timer3, 20);
}
}
This solution uses a additional equation unlike Ibu's solution, which used a multiplicative equation. The way it works is it takes a time increment (t), an opacity increment (o), and a opacity limit (l) in the equation, which is: (T = time of fade in miliseconds) [T = (l/o)*t]. the "20" represents the time increments or intervals (t), the ".01" represents the opacity increments (o), and the 1 represents the opacity limit (l). When you plug the numbers in the equation you get 2000 milliseconds (or 2 seconds). Here is the console log:

Notice how the opacity follows the opacity increment amount of .01 just like in the code. If you use the code Ibu made,
//I made slight edits but keeped the ESSENTIAL stuff in it.
var op = 0.01; // initial opacity
var timer = setInterval(function () {
if (op >= 1){
clearInterval(timer);
}
element.style.opacity = op;
op += op * 0.1;
}, 20);
you will get these numbers (or something similar) in you console log. Here is what I got.

Notice that there is no discernible pattern. If you ran Ibu's code, you would never know how long the fade was. You would have to grab a timer and guess and check 2 seconds. Nonetheless, Ibu's code did make a pretty nice fade in (it probably works for fade out. I don't know because I didn't use a fade out yet). My code will also work for a fade out. Let's just say you wanted 2 seconds for a fade out. You can do that with my code. Here is how it would look:
//Fade out. (Continued from the fade in.
function Timer2()
{
element.style.opacity = Op2;
Op2 = Op2 - .01;
console.log(Op2); //Option, but I recommend it for testing purposes.
if (Op2 < 0)
{
clearInterval(foo2);
}
}
All I did was change the opacity to 1 (or fully opaque). I changed the opacity increment to -.01 so it would start turning invisible. Lastly, I changed the opacity limit to 0. When it hits the opacity limit, the timer will stop. Same as the last one, except it used 1 instead of 0. When you run the code, here is what the console log should relatively look like.

As you can see, the .01 pattern still exists in the fade out. Both fades are smooth and precise. I hope these codes helped you or gave you insight on the topic. If you have any additions or suggestions let me know. Thank you for taking the time to view this!
setVisible(false); //you can't see me!
dispose(); //Destroy the JFrame object
Not too tricky.
Following redsquare: You should not use in href attribute javascript code like "javascript:void();" - it is wrong. Better use for example href="#" and then in Your event handler as a last command: "return false;". And even better - use in href correct link - if user have javascript disabled, web browser follows the link - in this case Your webpage should reload with input filled with value of that link.
Mac Users, let me save you the time:
string newString = url.Substring(18, (url.LastIndexOf(".") - 18))
There are method join
for string objects:
".".join(("a","b","c"))
put a int
infront of the all the voxelCoord
's...Like this below :
patch = numpyImage [int(voxelCoord[0]),int(voxelCoord[1])- int(voxelWidth/2):int(voxelCoord[1])+int(voxelWidth/2),int(voxelCoord[2])-int(voxelWidth/2):int(voxelCoord[2])+int(voxelWidth/2)]
If error comes for ".settings/language.settings.xml" or any such file you don't need to git.
Now if Staged file list empty, and Unstaged file list all files are marked as Ignored. You can pull. Otherwise, follow other answers.
To obtain the column count on a table, use this:
select count(id) from syscolumns where id = object_id('tablename')
and to pass a table to a function, try XML as show here:
create function dbo.ReadXml (@xmlMatrix xml)
returns table
as
return
( select
t.value('./@Salary', 'integer') as Salary,
t.value('./@Age', 'integer') as Age
from @xmlMatrix.nodes('//row') x(t)
)
go
declare @source table
( Salary integer,
age tinyint
)
insert into @source
select 10000, 25 union all
select 15000, 27 union all
select 12000, 18 union all
select 15000, 36 union all
select 16000, 57 union all
select 17000, 44 union all
select 18000, 32 union all
select 19000, 56 union all
select 25000, 34 union all
select 7500, 29
--select * from @source
declare @functionArgument xml
select @functionArgument =
( select
Salary as [row/@Salary],
Age as [row/@Age]
from @source
for xml path('')
)
--select @functionArgument as [@functionArgument]
select * from readXml(@functionArgument)

I believe that the correct answer has already been posted and accepted, yet there is an issue that I have experienced myself and that some others have mentioned here.
On certain platforms, various properties such as window dimensions (window.innerWidth
, window.innerHeight
) and the window.orientation
property will not be updated by the time that the event "orientationchange"
has fired. Many times, the property window.orientation
is undefined
for a few milliseconds after the firing of "orientationchange"
(at least it is in Chrome on iOS).
The best way that I found to handle this issue was:
var handleOrientationChange = (function() {
var struct = function(){
struct.parse();
};
struct.showPortraitView = function(){
alert("Portrait Orientation: " + window.orientation);
};
struct.showLandscapeView = function(){
alert("Landscape Orientation: " + window.orientation);
};
struct.parse = function(){
switch(window.orientation){
case 0:
//Portrait Orientation
this.showPortraitView();
break;
default:
//Landscape Orientation
if(!parseInt(window.orientation)
|| window.orientation === this.lastOrientation)
setTimeout(this, 10);
else
{
this.lastOrientation = window.orientation;
this.showLandscapeView();
}
break;
}
};
struct.lastOrientation = window.orientation;
return struct;
})();
window.addEventListener("orientationchange", handleOrientationChange, false);
I am checking to see if the orientation is either undefined or if the orientation is equal to the last orientation detected. If either is true, I wait ten milliseconds and then parse the orientation again. If the orientation is a proper value, I call the showXOrientation
functions. If the orientation is invalid, I continue to loop my checking function, waiting ten milliseconds each time, until it is valid.
Now, I would make a JSFiddle for this, as I usually did, but JSFiddle has not been working for me and my support bug for it was closed as no one else is reporting the same problem. If anyone else wants to turn this into a JSFiddle, please go ahead.
Thanks! I hope this helps!
a = 'dog'
address = id(a)
print(id(a))

ctypes.cast(address, ctypes.py_object).value #value at old address is intact
one option is to put multi value with comma seperated

and in the server side separate them
