The fastest way to do file I/O from C# is to use the Windows ReadFile and WriteFile functions. I have written a C# class that encapsulates this capability as well as a benchmarking program that looks at differnet I/O methods, including BinaryReader and BinaryWriter. See my blog post at:
http://designingefficientsoftware.wordpress.com/2011/03/03/efficient-file-io-from-csharp/
You can use two way
1) if ( val == null )
2) if ( val === undefine )
There's two types of superfluous #include files:
There's 2 ways in my experience that works well to detecting it:
gcc -H or cl.exe /showincludes (resolve problem 2)
In real world, you can export CFLAGS=-H before make, if all the Makefile's not override CFLAGS options. Or as I used, you can create a cc/g++ wrapper to add -H options forcibly to each invoke of $(CC) and $(CXX). and prepend the wrapper's directory to $PATH variable, then your make will all uses you wrapper command instead. Of course your wrapper should invoke the real gcc compiler. This tricks need to change if your Makefile uses gcc directly. instead of $(CC) or $(CXX) or by implied rules.
You can also compile a single file by tweaking with the command line. But if you want to clean headers for the whole project. You can capture all the output by:
make clean
make 2>&1 | tee result.txt
PC-Lint/FlexeLint(resolve problem both 1 and 2)
make sure add the +e766 options, this warning is about: unused header files.
pclint/flint -vf ...
This will cause pclint output included header files, nested header files will be indented appropriately.
The minimal setup for an HTTPS server in Node.js would be something like this :
var https = require('https');
var fs = require('fs');
var httpsOptions = {
key: fs.readFileSync('path/to/server-key.pem'),
cert: fs.readFileSync('path/to/server-crt.pem')
};
var app = function (req, res) {
res.writeHead(200);
res.end("hello world\n");
}
https.createServer(httpsOptions, app).listen(4433);
If you also want to support http requests, you need to make just this small modification :
var http = require('http');
var https = require('https');
var fs = require('fs');
var httpsOptions = {
key: fs.readFileSync('path/to/server-key.pem'),
cert: fs.readFileSync('path/to/server-crt.pem')
};
var app = function (req, res) {
res.writeHead(200);
res.end("hello world\n");
}
http.createServer(app).listen(8888);
https.createServer(httpsOptions, app).listen(4433);
For Each row As DataGridViewRow In yourDGV.SelectedRows
yourDGV.Rows.Remove(row)
Next
This will delete all rows that had been selected.
You can do which python
and see if its pointing to the one in virtual env.
Wait -- did you actually mean that "the same number of rows ... are being processed" or that "the same number of rows are being returned"? In general, the outer join would process many more rows, including those for which there is no match, even if it returns the same number of records.
I ended up here and my issue was that I was querying for
{$not: {email: /@domain.com/}}
instead of
{email: {$not: /@domain.com/}}
If you are using this for Angular, then export a function via a named export. Such as:
function someFunc(){}
export { someFunc as someFuncName }
otherwise, Angular will complain that object is not a function.
Please check my working code.
function sendMail()
{
$config = Array(
'protocol' => 'smtp',
'smtp_host' => 'ssl://smtp.googlemail.com',
'smtp_port' => 465,
'smtp_user' => '[email protected]', // change it to yours
'smtp_pass' => 'xxx', // change it to yours
'mailtype' => 'html',
'charset' => 'iso-8859-1',
'wordwrap' => TRUE
);
$message = '';
$this->load->library('email', $config);
$this->email->set_newline("\r\n");
$this->email->from('[email protected]'); // change it to yours
$this->email->to('[email protected]');// change it to yours
$this->email->subject('Resume from JobsBuddy for your Job posting');
$this->email->message($message);
if($this->email->send())
{
echo 'Email sent.';
}
else
{
show_error($this->email->print_debugger());
}
}
Try this :
string myStr = ...
myStr = myStr.Replace("\n", Environment.NewLine)
If Zip Code
allows characters and digits (alphanumeric), below regex would be used where it matches, 5 or 9 or 10 alphanumeric characters with one hypen (-
):
^([0-9A-Za-z]{5}|[0-9A-Za-z]{9}|(([0-9a-zA-Z]{5}-){1}[0-9a-zA-Z]{4}))$
Or using regular expressions
"rmlike" <- function(...) {
names <- sapply(
match.call(expand.dots = FALSE)$..., as.character)
names = paste(names,collapse="|")
Vars <- ls(1)
r <- Vars[grep(paste("^(",names,").*",sep=""),Vars)]
rm(list=r,pos=1)
}
rmlike(temp)
I found an other way to achieve this...
Step 1: Put the dialog opening code in a method (Or Function in C).
Step 2: Inside the onClick of yes
(Your positiveButton), call this dialog opening
method recursively if your condition is not satisfied (By using if...else...). Like below :
private void openSave() {
final AlertDialog.Builder builder=new AlertDialog.Builder(Phase2Activity.this);
builder.setTitle("SAVE")
.setIcon(R.drawable.ic_save_icon)
.setPositiveButton("Save", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
if((!editText.getText().toString().isEmpty() && !editText1.getText().toString().isEmpty())){
createPdf(fileName,title,file);
}else {
openSave();
Toast.makeText(Phase2Activity.this, "Some fields are empty.", Toast.LENGTH_SHORT).show();
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
})
.setCancelable(false)
.create()
.show();
}
But this will make the dialog disappear just for a moment and it will appear again instantly. :)
Since pip
is an executable and which
returns path of executables or filenames in environment. It is correct. Pip module is installed in site-packages but the executable is installed in bin.
Added some supplemental code to the accepted answer. It improves upon answers just using Random and allows for some password options. I also liked some of the options from the KeePass answer but did not want to include the executable in my solution.
private string RandomPassword(int length, bool includeCharacters, bool includeNumbers, bool includeUppercase, bool includeNonAlphaNumericCharacters, bool includeLookAlikes)
{
if (length < 8 || length > 128) throw new ArgumentOutOfRangeException("length");
if (!includeCharacters && !includeNumbers && !includeNonAlphaNumericCharacters) throw new ArgumentException("RandomPassword-Key arguments all false, no values would be returned");
string pw = "";
do
{
pw += System.Web.Security.Membership.GeneratePassword(128, 25);
pw = RemoveCharacters(pw, includeCharacters, includeNumbers, includeUppercase, includeNonAlphaNumericCharacters, includeLookAlikes);
} while (pw.Length < length);
return pw.Substring(0, length);
}
private string RemoveCharacters(string passwordString, bool includeCharacters, bool includeNumbers, bool includeUppercase, bool includeNonAlphaNumericCharacters, bool includeLookAlikes)
{
if (!includeCharacters)
{
var remove = new string[] { "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z" };
foreach (string r in remove)
{
passwordString = passwordString.Replace(r, string.Empty);
passwordString = passwordString.Replace(r.ToUpper(), string.Empty);
}
}
if (!includeNumbers)
{
var remove = new string[] { "0", "1", "2", "3", "4", "5", "6", "7", "8", "9" };
foreach (string r in remove)
passwordString = passwordString.Replace(r, string.Empty);
}
if (!includeUppercase)
passwordString = passwordString.ToLower();
if (!includeNonAlphaNumericCharacters)
{
var remove = new string[] { "!", "@", "#", "$", "%", "^", "&", "*", "(", ")", "-", "_", "+", "=", "{", "}", "[", "]", "|", "\\", ":", ";", "<", ">", "/", "?", "." };
foreach (string r in remove)
passwordString = passwordString.Replace(r, string.Empty);
}
if (!includeLookAlikes)
{
var remove = new string[] { "(", ")", "0", "O", "o", "1", "i", "I", "l", "|", "!", ":", ";" };
foreach (string r in remove)
passwordString = passwordString.Replace(r, string.Empty);
}
return passwordString;
}
This was the first link when I searched for generating random passwords and the following is out of scope for the current question but might be important to consider.
System.Web.Security.Membership.GeneratePassword
is cryptographically secure with a minimum of 20% of the characters being Non-Alphanumeric.In an insert statement you wouldn't have an existing row to do a where claues on? You are inserting a new row, did you mean to do an update statment?
update users set username='JACK' and password='123' WHERE id='1';
#!/bin/sh
# Return relative path from canonical absolute dir path $1 to canonical
# absolute dir path $2 ($1 and/or $2 may end with one or no "/").
# Does only need POSIX shell builtins (no external command)
relPath () {
local common path up
common=${1%/} path=${2%/}/
while test "${path#"$common"/}" = "$path"; do
common=${common%/*} up=../$up
done
path=$up${path#"$common"/}; path=${path%/}; printf %s "${path:-.}"
}
# Return relative path from dir $1 to dir $2 (Does not impose any
# restrictions on $1 and $2 but requires GNU Core Utility "readlink"
# HINT: busybox's "readlink" does not support option '-m', only '-f'
# which requires that all but the last path component must exist)
relpath () { relPath "$(readlink -m "$1")" "$(readlink -m "$2")"; }
Above shell script was inspired by pini's (Thanks!). It triggers a bug in the syntax highlighting module of Stack Overflow (at least in my preview frame). So please ignore if highlighting is incorrect.
Some notes:
Except for the mentioned backslash sequences the last line of function "relPath" outputs pathnames compatible to python:
path=$up${path#"$common"/}; path=${path%/}; printf %s "${path:-.}"
Last line can be replaced (and simplified) by line
printf %s "$up${path#"$common"/}"
I prefer the latter because
Filenames can be directly appended to dir paths obtained by relPath, e.g.:
ln -s "$(relpath "<fromDir>" "<toDir>")<file>" "<fromDir>"
Symbolic links in the same dir created with this method do not have
the ugly "./"
prepended to the filename.

A minor update to this: a sender should never set the Return-Path:
header. There's no such thing as a Return-Path:
header for a message in transit. That header is set by the MTA that makes final delivery, and is generally set to the value of the 5321.From
unless the local system needs some kind of quirky routing.
It's a common misunderstanding because users rarely see an email without a Return-Path:
header in their mailboxes. This is because they always see delivered messages, but an MTA should never see a Return-Path:
header on a message in transit. See http://tools.ietf.org/html/rfc5321#section-4.4
You can define two entry points in your webpack configuration, one for your normal js and the other one for minified js. Then you should output your bundle with its name, and configure UglifyJS plugin to include min.js files. See the example webpack configuration for more details:
module.exports = {
entry: {
'bundle': './src/index.js',
'bundle.min': './src/index.js',
},
output: {
path: path.resolve(__dirname, 'dist'),
filename: "[name].js"
},
plugins: [
new webpack.optimize.UglifyJsPlugin({
include: /\.min\.js$/,
minimize: true
})
]
};
After running webpack, you will get bundle.js and bundle.min.js in your dist folder, no need for extra plugin.
Very nice solution by praneybehl, but if someone wants to save the data as a csv
file and using a blob
method then they can refer this:
function JSONToCSVConvertor(JSONData, ReportTitle, ShowLabel) {
//If JSONData is not an object then JSON.parse will parse the JSON string in an Object
var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;
var CSV = '';
//This condition will generate the Label/Header
if (ShowLabel) {
var row = "";
//This loop will extract the label from 1st index of on array
for (var index in arrData[0]) {
//Now convert each value to string and comma-seprated
row += index + ',';
}
row = row.slice(0, -1);
//append Label row with line break
CSV += row + '\r\n';
}
//1st loop is to extract each row
for (var i = 0; i < arrData.length; i++) {
var row = "";
//2nd loop will extract each column and convert it in string comma-seprated
for (var index in arrData[i]) {
row += '"' + arrData[i][index] + '",';
}
row.slice(0, row.length - 1);
//add a line break after each row
CSV += row + '\r\n';
}
if (CSV == '') {
alert("Invalid data");
return;
}
//this trick will generate a temp "a" tag
var link = document.createElement("a");
link.id = "lnkDwnldLnk";
//this part will append the anchor tag and remove it after automatic click
document.body.appendChild(link);
var csv = CSV;
blob = new Blob([csv], { type: 'text/csv' });
var csvUrl = window.webkitURL.createObjectURL(blob);
var filename = (ReportTitle || 'UserExport') + '.csv';
$("#lnkDwnldLnk")
.attr({
'download': filename,
'href': csvUrl
});
$('#lnkDwnldLnk')[0].click();
document.body.removeChild(link);
}
I assumed the first DIV is #content
:
<div id="content">
<img src="@Url.Content("~/images/image1.bmp")" alt="" />
<img src="@Url.Content("~/images/image2.bmp")" alt="" />
<img src="@Url.Content("~/images/image3.bmp")" alt="" />
</div>
And CSS :
#content{
width: 700px;
display: block;
height: auto;
}
#content > img{
float: left; width: 200px;
height: 200px;
margin: 5px 8px;
}
Why not encapsulate a set with a list, sort like:
new ArrayList( new LinkedHashSet() )
This leaves the other implementation for someone who is a real master of Collections ;-)
From Wikipedia:
In PHP, the scope resolution operator is also called Paamayim Nekudotayim (Hebrew: ?????? ?????????), which means “double colon” in Hebrew.
The name "Paamayim Nekudotayim" was introduced in the Israeli-developed Zend Engine 0.5 used in PHP 3. Although it has been confusing to many developers who do not speak Hebrew, it is still being used in PHP 5, as in this sample error message:
$ php -r :: Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM
As of PHP 5.4, error messages concerning the scope resolution operator still include this name, but have clarified its meaning somewhat:
$ php -r :: Parse error: syntax error, unexpected '::' (T_PAAMAYIM_NEKUDOTAYIM)
From the official PHP documentation:
The Scope Resolution Operator (also called Paamayim Nekudotayim) or in simpler terms, the double colon, is a token that allows access to static, constant, and overridden properties or methods of a class.
When referencing these items from outside the class definition, use the name of the class.
As of PHP 5.3.0, it's possible to reference the class using a variable. The variable's value can not be a keyword (e.g. self, parent and static).
Paamayim Nekudotayim would, at first, seem like a strange choice for naming a double-colon. However, while writing the Zend Engine 0.5 (which powers PHP 3), that's what the Zend team decided to call it. It actually does mean double-colon - in Hebrew!
sed -i.bak 's/\(aaa=\).*/\1"xxx"/g' your_file
You could also get all relevant details from performance_schema:
SELECT
OBJECT_SCHEMA
,OBJECT_NAME
,GROUP_CONCAT(DISTINCT EXTERNAL_LOCK)
FROM performance_schema.table_handles
WHERE EXTERNAL_LOCK IS NOT NULL
GROUP BY
OBJECT_SCHEMA
,OBJECT_NAME
This works similar as
show open tables WHERE In_use > 0
Adding on to the answer from @Ohmen, you could also add an external
flag to create the data volume outside of docker compose. This way docker compose would not attempt to create it. Also you wouldn't have to worry about losing the data inside the data-volume in the event of $ docker-compose down -v
.
The below example is from the official page.
version: "3.8"
services:
db:
image: postgres
volumes:
- data:/var/lib/postgresql/data
volumes:
data:
external: true
You can't run two SQL statements into one like you are doing.
You can't "execute" a select query.
db is an object and you haven't set it to anything: (e.g. set db = currentdb)
In VBA integer types can hold up to max of 32767 - I would be tempted to use Long.
You might want to be a bit more specific about the date you are inserting:
INSERT INTO Test (Start_Date) VALUES ('#" & format(InDate, "mm/dd/yyyy") & "#' );"
SQL Server has support for spatial related information. You can see more at http://www.microsoft.com/sqlserver/2008/en/us/spatial-data.aspx.
Alternativly you can store the information as two basic fields, usually a float is the standard data type reported by most devices and is accurate enough for within an inch or two - more than adequate for Google Maps.
This works
psql dbname -F , --no-align -c "SELECT * FROM TABLE"
Add this function to your ~/.bashrc
and restart your terminal or run source ~/.bashrc
function lock() {
gnome-screensaver
gnome-screensaver-command --lock
}
This way these two commands will run whenever you enter lock
in your terminal.
In your specific case creating an alias
may work, but I don't recommend it. Intuitively we would think the value of an alias would run the same as if you entered the value in the terminal. However that's not the case:
The rules concerning the definition and use of aliases are somewhat confusing.
and
For almost every purpose, shell functions are preferred over aliases.
So don't use an alias unless you have to. https://ss64.com/bash/alias.html
I got this answer from here. and its works for me
Require local
Change to
Require all granted
Order Deny,Allow
Allow from all
Also you can use this. For the razor pages, it is better to use it than the others.

PrimeFaces is built on jQuery, so here's jQuery's "Events" documentation:
http://api.jquery.com/category/events/
http://api.jquery.com/category/events/form-events/
http://api.jquery.com/category/events/keyboard-events/
http://api.jquery.com/category/events/mouse-events/
http://api.jquery.com/category/events/browser-events/
Below, I've listed some of the more common events, with comments about where they can be used (taken from jQuery documentation).
Mouse Events
(Any HTML element can receive these events.)
click
dblclick
mousedown
mousemove
mouseover
mouseout
mouseup
Keyboard Events
(These events can be attached to any element, but the event is only sent to the element that has the focus. Focusable elements can vary between browsers, but form elements can always get focus so are reasonable candidates for these event types.)
keydown
keypress
keyup
Form Events
blur
(In recent browsers, the domain of the event has been extended to include all element types.)
change
(This event is limited to <input>
elements, <textarea>
boxes and <select>
elements.)
focus
(This event is implicitly applicable to a limited set of elements, such as form elements (<input>
, <select>
, etc.) and links (<a href>
). In recent browser versions, the event can be extended to include all element types by explicitly setting the element's tabindex property. An element can gain focus via keyboard commands, such as the Tab key, or by mouse clicks on the element.)
select
(This event is limited to <input type="text">
fields and <textarea>
boxes.)
submit
(It can only be attached to <form>
elements.)
I don't actually find any of the presented solutions here to be fully complete so I'll add my own. Nothing new here. You can stitch this together from the other presented solutions plus various comments.
There are at least two things you'll have to make sure:
Make sure you pass the table name to the getTables()
method,
rather than passing a null value. In the first case you let the
database server filter the result for you, in the second you request
a list of all tables from the server and then filter the list
locally. The former is much faster if you are only searching for a
single table.
Make sure to check the table name from the resultset with an equals
match. The reason is that the getTables()
does pattern matching on
the query for the table and the _
character is a wildcard in SQL.
Suppose you are checking for the existence of a table named
EMPLOYEE_SALARY
. You'll then get a match on EMPLOYEESSALARY
too
which is not what you want.
Ohh, and do remember to close those resultsets. Since Java 7 you would want to use a try-with-resources statement for that.
Here's a complete solution:
public static boolean tableExist(Connection conn, String tableName) throws SQLException {
boolean tExists = false;
try (ResultSet rs = conn.getMetaData().getTables(null, null, tableName, null)) {
while (rs.next()) {
String tName = rs.getString("TABLE_NAME");
if (tName != null && tName.equals(tableName)) {
tExists = true;
break;
}
}
}
return tExists;
}
You may want to consider what you pass as the types
parameter (4th parameter) on your getTables()
call. Normally I would just leave at null
because you don't want to restrict yourself. A VIEW is as good as a TABLE, right? These days many databases allow you to update through a VIEW so restricting yourself to only TABLE type is in most cases not the way to go. YMMV.
I'm surprised no one has suggested using a result filter. This is the cleanest way to globally hook into the action/result pipeline:
public class JsonResultFilter : IResultFilter
{
public int? MaxJsonLength { get; set; }
public int? RecursionLimit { get; set; }
public void OnResultExecuting(ResultExecutingContext filterContext)
{
if (filterContext.Result is JsonResult jsonResult)
{
// override properties only if they're not set
jsonResult.MaxJsonLength = jsonResult.MaxJsonLength ?? MaxJsonLength;
jsonResult.RecursionLimit = jsonResult.RecursionLimit ?? RecursionLimit;
}
}
public void OnResultExecuted(ResultExecutedContext filterContext)
{
}
}
Then, register an instance of that class using GlobalFilters.Filters
:
GlobalFilters.Filters.Add(new JsonResultFilter { MaxJsonLength = int.MaxValue });
This kind of thing doesn't just magically happen on its own; you changed something! In industry we use version control to make regular savepoints, so when something goes wrong we can trace back the specific changes we made that resulted in that problem.
Since you haven't done that here, we can only really guess. In Visual Studio, Intellisense (the technology that gives you auto-complete dropdowns and those squiggly red lines) works separately from the actual C++ compiler under the bonnet, and sometimes gets things a bit wrong.
In this case I'd ask why you're including both cstdlib
and stdlib.h
; you should only use one of them, and I recommend the former. They are basically the same header, a C header, but cstdlib
puts them in the namespace std
in order to "C++-ise" them. In theory, including both wouldn't conflict but, well, this is Microsoft we're talking about. Their C++ toolchain sometimes leaves something to be desired. Any time the Intellisense disagrees with the compiler has to be considered a bug, whichever way you look at it!
Anyway, your use of using namespace std
(which I would recommend against, in future) means that std::system
from cstdlib
now conflicts with system
from stdlib.h
. I can't explain what's going on with std::cout
and std::cin
.
Try removing #include <stdlib.h>
and see what happens.
If your program is building successfully then you don't need to worry too much about this, but I can imagine the false positives being annoying when you're working in your IDE.
I have been hasseling with that as other folks have.
I used the criteria;
=countif(matchingList,C2)=0
where matchingList is the list that i am using as a filter.
have a look at this
http://www.youtube.com/watch?v=x47VFMhRLnM&list=PL63A7644FE57C97F4&index=30
The trick i found is that normally you would have the column heading in the criteria matching the data column heading. this will not work for criteria that is a formula.
What I found was if I left the column heading blank for only the criteria that has the countif
formula in the advanced filter works. If I have the column heading i.e. the column heading for column C2 in my formula example then the filter return no output.
Hope this helps
It appears this can be done. I'm unable to determine the version of GCC that it was added, but it was sometime before June 2010.
Here's an example:
#pragma GCC diagnostic error "-Wuninitialized"
foo(a); /* error is given for this one */
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wuninitialized"
foo(b); /* no diagnostic for this one */
#pragma GCC diagnostic pop
foo(c); /* error is given for this one */
#pragma GCC diagnostic pop
foo(d); /* depends on command line options */
There is a solution:
<resources>
<item name="text_line_spacing" format="float" type="dimen">1.0</item>
</resources>
In this way, your float number will be under @dimen. Notice that you can use other "format" and/or "type" modifiers, where format stands for:
Format = enclosing data type:
and type stands for:
Type = resource type (referenced with R.XXXXX.name):
To fetch resource from code, you should use this snippet:
TypedValue outValue = new TypedValue();
getResources().getValue(R.dimen.text_line_spacing, outValue, true);
float value = outValue.getFloat();
I know that this is confusing (you'd expect call like getResources().getDimension(R.dimen.text_line_spacing)
), but Android dimensions
have special treatment and pure "float" number is not valid dimension.
Additionally, there is small "hack" to put float number into dimension, but be WARNED that this is really hack, and you are risking chance to lose float range and precision.
<resources>
<dimen name="text_line_spacing">2.025px</dimen>
</resources>
and from code, you can get that float by
float lineSpacing = getResources().getDimension(R.dimen.text_line_spacing);
in this case, value of lineSpacing
is 2.024993896484375
, and not 2.025
as you would expected.
Try to use this xPath expression:
//book/title[@lang='it']/..
That should give you all book nodes in "it" lang
I just fixed this in mine. Large project, two files. One was "ReallyLargeNameView" and another was "ReallyLargeNameViewController"
Based on the 2nd answer chosen above, I decided I should clean my build. Nada, but I was still suspect of XCode (as I have two identical classes, should abstract them but eh...) So one's working, one's not. File's owner names are so far as copy and pasted, outlets rehooked up, xCode rebooted, still nothing.
So I delete the similar named class (which is a view). Soon, new error "outlet inside not hooked up" literally was "webView not key value" blah... basically saying "Visual Studio's better". Anyway... I erase the smaller named file, and bam, it works.
XCode is confused by similar-named files. And the project is large enough to need rebooting a bit, that may be part of it.
Wish I had a more technical answer than "XCode is confused", but well, xCode gets confused a lot at this point. Unconfused it the same way I'd help a little kid. It works now, :) Should benefit others if the above doesn't fix anything.
Always remember to clean your builds (by deleting off the simulator too)

As vim's own help on set background
says, "Setting this option does not change the background color, it tells Vim what the background color looks like. For changing the background color, see |:hi-normal|."
For example
:highlight Normal ctermfg=grey ctermbg=darkblue
will write in white on blue on your color terminal.
List<object>.AddRange(object[])
should do the trick. It will avoid all sorts of useless memory allocation.
You could also use Linq, somewhat like this: object[].Cast<object>().ToList()
When a module is loaded from a file in Python, __file__
is set to its path. You can then use that with other functions to find the directory that the file is located in.
Taking your examples one at a time:
A = os.path.join(os.path.dirname(__file__), '..')
# A is the parent directory of the directory where program resides.
B = os.path.dirname(os.path.realpath(__file__))
# B is the canonicalised (?) directory where the program resides.
C = os.path.abspath(os.path.dirname(__file__))
# C is the absolute path of the directory where the program resides.
You can see the various values returned from these here:
import os
print(__file__)
print(os.path.join(os.path.dirname(__file__), '..'))
print(os.path.dirname(os.path.realpath(__file__)))
print(os.path.abspath(os.path.dirname(__file__)))
and make sure you run it from different locations (such as ./text.py
, ~/python/text.py
and so forth) to see what difference that makes.
I just want to address some confusion first. __file__
is not a wildcard it is an attribute. Double underscore attributes and methods are considered to be "special" by convention and serve a special purpose.
http://docs.python.org/reference/datamodel.html shows many of the special methods and attributes, if not all of them.
In this case __file__
is an attribute of a module (a module object). In Python a .py
file is a module. So import amodule
will have an attribute of __file__
which means different things under difference circumstances.
Taken from the docs:
__file__
is the pathname of the file from which the module was loaded, if it was loaded from a file. The__file__
attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.
In your case the module is accessing it's own __file__
attribute in the global namespace.
To see this in action try:
# file: test.py
print globals()
print __file__
And run:
python test.py
{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__file__':
'test_print__file__.py', '__doc__': None, '__package__': None}
test_print__file__.py
You'll need to join twice:
SELECT home.*, away.*, g.network, g.date_start
FROM game AS g
INNER JOIN team AS home
ON home.importid = g.home
INNER JOIN team AS away
ON away.importid = g.away
ORDER BY g.date_start DESC
LIMIT 7
imageView.setLayoutParams
(new ViewGroup.MarginLayoutParams
(width, ViewGroup.LayoutParams.MATCH_PARENT));
The Type of layout params depends on the parent view group. If you put the wrong one it will cause exception.
A trailing comma in a JSON array caused my Perl 5.16 to hang, possibly because it kept backtracking. I had to add a backtrack-terminating directive:
(?<json> \s* (?: (?&number) | (?&boolean) | (?&string) | (?&array) | (?&object) )(*PRUNE) \s* )
^^^^^^^^
This way, once it identifies a construct that is not 'optional' (*
or ?
), it shouldn't try backtracking over it to try to identify it as something else.
I was looking for an example that had default kwargs using type annotation:
def test_var_kwarg(a: str, b: str='B', c: str='', **kwargs) -> str:
return ' '.join([a, b, c, str(kwargs)])
example:
>>> print(test_var_kwarg('A', c='okay'))
A B okay {}
>>> d = {'f': 'F', 'g': 'G'}
>>> print(test_var_kwarg('a', c='c', b='b', **d))
a b c {'f': 'F', 'g': 'G'}
>>> print(test_var_kwarg('a', 'b', 'c'))
a b c {}
Try this
<xs:element name="description" type="xs:string" minOccurs="0" maxOccurs="1" />
if you want 0 or 1 "description" elements, Or
<xs:element name="description" type="xs:string" minOccurs="0" maxOccurs="unbounded" />
if you want 0 to infinity number of "description" elements.

If you don't have access to the v$ views (as suggested by Quassnoi) there are two alternatives
select utl_inaddr.get_host_name from dual
and
select sys_context('USERENV','SERVER_HOST') from dual
Personally I'd tend towards the last as it doesn't require any grants/privileges which makes it easier from stored procedures.
You can first get all the view controllers in the array and then after checking with the corresponding view controller class, you can delete the one you want.
Here is small piece of code:
NSArray* tempVCA = [self.navigationController viewControllers];
for(UIViewController *tempVC in tempVCA)
{
if([tempVC isKindOfClass:[urViewControllerClass class]])
{
[tempVC removeFromParentViewController];
}
}
I think this will make your work easier.
Check out javapassion, they have a number of courses that encompass web programming, and were free (until circumstances conspired to make the website need to support itself).
Even with the nominal fee, you get a lot for an entire year. It's a bargain compared to the amount of time you'll be investing.
The other options are to look to Oracle's online tutorials, they lack the glitz of Codeacademy, but are surprisingly good. I haven't read the one on web programming, that might be embedded in the Java EE tutorial(s), which is not tuned for a new beginner to Java.
localhost
is special in MySQL, it means a connection over a UNIX socket (or named pipes on Windows, I believe) as opposed to a TCP/IP socket. Using %
as the host does not include localhost
, hence the need to explicitly specify it.
When we give any command, the streams of that command are stored in the memory location called buffer(a temporary memory location) in our computer. When all the temporary memory location is full then we use flush(), which flushes all the streams of data and executes them completely and gives a new space to new streams in buffer temporary location. -Hope you will understand
Why are you doing a group by on an update statement? Are you sure that's not the part that's causing the query to fail? Try this:

TotalZ = Sum(DetailTbl.Z)
from
DetailTbl
where
DetailTbl.MasterID = MasterID
There are a few steps you have to keep in mind.
Now there are two scenarios If you are developing it in your local machine login to your google account in your browser, this way the google recognizes the machine.
If you have deployed the application onto a server then after the first request you will get an authentication error, so you have to give access to the server, just go here to give access- https://www.google.com/accounts/DisplayUnlockCaptcha

This function gives you all the diffs (and what stayed the same) based on the dictionary keys only. It also highlights some nice Dict comprehension, Set operations and python 3.6 type annotations :)

In this example, I am assuming the end user also has an account. If this isn't he case, then the rest of the approach is unlikely to work.
When you create the JWT, persist it in the database, associated with the account that is logging in. This does mean that just from the JWT you could pull out additional information about the user, so depending on the environment, this may or may not be OK.
On every request after, not only do you perform the standard validation that (I hope) comes with what ever framework you use (that validates the JWT is valid), it also includes soemthing like the user ID or another token (that needs to match that in the database).
When you log out, delete the cookie (if using) and invalidate the JWT (string) from the database. If the cookie can't be deleted from the client side, then at least the log out process will ensure the token is destroyed.
I found this approach, coupled with another unique identifier (so there are 2 persist items in the database and are available to the front end) with the session to be very resilient
It passes control to the next matching route. In the example you give, for instance, you might look up the user in the database if an id
was given, and assign it to req.user
.
Below, you could have a route like:
app.get('/users', function(req, res) {
// check for and maybe do something with req.user
});
Since /users/123 will match the route in your example first, that will first check and find user 123
; then /users
can do something with the result of that.
Route middleware is a more flexible and powerful tool, though, in my opinion, since it doesn't rely on a particular URI scheme or route ordering. I'd be inclined to model the example shown like this, assuming a Users
model with an async findOne()
:
function loadUser(req, res, next) {
if (req.params.userId) {
Users.findOne({ id: req.params.userId }, function(err, user) {
if (err) {
next(new Error("Couldn't find user: " + err));
return;
}
req.user = user;
next();
});
} else {
next();
}
}
// ...
app.get('/user/:userId', loadUser, function(req, res) {
// do something with req.user
});
app.get('/users/:userId?', loadUser, function(req, res) {
// if req.user was set, it's because userId was specified (and we found the user).
});
// Pretend there's a "loadItem()" which operates similarly, but with itemId.
app.get('/item/:itemId/addTo/:userId', loadItem, loadUser, function(req, res) {
req.user.items.append(req.item.name);
});
Being able to control flow like this is pretty handy. You might want to have certain pages only be available to users with an admin flag:
/**
* Only allows the page to be accessed if the user is an admin.
* Requires use of `loadUser` middleware.
*/
function requireAdmin(req, res, next) {
if (!req.user || !req.user.admin) {
next(new Error("Permission denied."));
return;
}
next();
}
app.get('/top/secret', loadUser, requireAdmin, function(req, res) {
res.send('blahblahblah');
});
Hope this gave you some inspiration!
var optionTexts = [];
$("ul li").each(function() { optionTexts.push($(this).text()) });
...should do the trick. To get the final output you're looking for, join()
plus some concatenation will do nicely:
var quotedCSV = '"' + optionTexts.join('", "') + '"';

Based on MDN Web Docs you can set multiple background using shorthand background
property or individual properties except for background-color
. In your case, you can do a trick using linear-gradient
like this:
background-image: url('images/checked.png'), linear-gradient(to right, #6DB3F2, #6DB3F2);
The first item (image) in the parameter will be put on top. The second item (color background) will be put underneath the first. You can also set other properties individually. For example, to set the image size and position.
background-size: 30px 30px;
background-position: bottom right;
background-repeat: no-repeat;
Benefit of this method is you can implement it for other cases easily, for example, you want to make the blue color overlaying the image with certain opacity.
background-image: linear-gradient(to right, rgba(109, 179, 242, .6), rgba(109, 179, 242, .6)), url('images/checked.png');
background-size: cover, contain;
background-position: center, right bottom;
background-repeat: no-repeat, no-repeat;
Individual property parameters are set respectively. Because the image is put underneath the color overlay, its property parameters are also placed after color overlay parameters.
What files are you importing into the files getting the R error?
My understanding of the R file are that they are automatically generated reference lists to all attributes within the Android app. Therefore, you can't change it yourself.
Are you using Eclipse to build this project? Were the older projects getting these errors made before updating Eclipse? What are the references that are getting errors?
Check to make sure that you've not imported another R file from other copied code in another app.
In this example the loop is run every second for ten seconds:

I combined two solutions and it works fine for me.
window.addEventListener("orientationchange", function() {

alert("LANSCAPE")
}
}, false);
exclude()
The Django issue tracker has the remarkable entry #5763, titled "Queryset doesn't have a "not equal" filter operator". It is remarkable because (as of April 2016) it was "opened 9 years ago" (in the Django stone age), "closed 4 years ago", and "last changed 5 months ago".
Read through the discussion, it is interesting.
Basically, some people argue __ne
should be added
while others say exclude()
is clearer and hence __ne
should not be added.
(I agree with the former, because the latter argument is
roughly equivalent to saying Python should not have !=
because
it has ==
and not
already...)
Also you can use Lodash to direct convert object to array:
_.toArray({0:{a:4},1:{a:6},2:{a:5}})
[{a:4},{a:6},{a:5}]
In your case:
_.toArray(subjects).map((subject, i) => (
<li className="travelcompany-input" key={i}>
<span className="input-label">Name: {subject[name]}</span>
</li>
))}
<ImageView
android:id="@+id/listViewIcon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/settings"/>

You just need a little extra whitespace around the minus sign, and backticks:
COUNT=`expr $FIRSTV - $SECONDV`
Be aware of the exit status:
The exit status is 0 if EXPRESSION is neither null nor 0, 1 if EXPRESSION is null or 0.
Keep this in mind when using the expression in a bash script in combination with set -e which will exit immediately if a command exits with a non-zero status.
You can only use Core Graphics (Quartz, 2D only) transforms directly applied to a UIView's transform property. To get the effects in coverflow, you'll have to use CATransform3D, which are applied in 3-D space, and so can give you the perspective view you want. You can only apply CATransform3Ds to layers, not views, so you're going to have to switch to layers for this.
Check out the "CovertFlow" sample that comes with Xcode. It's mac-only (ie not for iPhone), but a lot of the concepts transfer well.
If you have created or cloned another repository and you were not able to pull from origin
or upstream
adding the ssh key at that directory using the following command worked.
This is the error I was getting here:
Warning: Permanently added the RSA host key for IP address '61:fd9b::8c52:7203' to the list of known hosts.
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
I used the following command, this works:
ssh-add ~/.ssh/id_rsa_YOUR_COMPANY_NAME
Yes, this is confusing...
According to this blog post, it looks like this is an omission from WPF.
To make it work you need to use a style:
<Border Name="ClearButtonBorder" Grid.Column="1" CornerRadius="0,3,3,0">
<Border.Style>
<Style>
<Setter Property="Border.Background" Value="Blue"/>
<Style.Triggers>
<Trigger Property="Border.IsMouseOver" Value="True">
<Setter Property="Border.Background" Value="Green" />
</Trigger>
</Style.Triggers>
</Style>
</Border.Style>
<TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="X" />
</Border>
I guess this problem isn't that common as most people tend to factor out this sort of thing into a style, so it can be used on multiple controls.
Regardless to Your example
select length('Burger') from dual;
I hope this will help :)
Just add these lines of code to your activity/fragment java file:
getWindow().setFlags(
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
);
Sometimes you need to grep the process by name - in that case:
ps aux | grep simple-scan
Example output:
simple-scan 1090 0.0 0.1 4248 1432 ? S Jun11 0:00
Here's a simple example :
Process.Start("cmd","/C copy c:\\file.txt lpt1");
You can do forward typedef. But to do
typedef A B;
you must first forward declare A
:
class A;
typedef A B;
@Pantelis answer somehow steered me to a solution for a similar misunderstanding. A message board project I'm working on needs to show an optional image. I was having fits trying to get the src=imagefile to concatenate a fixed path and variable filename string until I saw the quirky use of "''" quotes :-)
<template id="symp-tmpl">
<div>
<div v-for="item in items" style="clear: both;">
<div v-if="(item.imagefile !== '[none]')">
<img v-bind:src="'/storage/userimages/' + item.imagefile">
</div>
sub: <span>@{{ item.subject }}</span>
<span v-if="(login == item.author)">[edit]</span>
<br>@{{ item.author }}
<br>msg: <span>@{{ item.message }}</span>
</div>
</div>
</template>
you can also use a hashmap for this
@GetMapping
public HashMap<String, Object> get() {
HashMap<String, Object> map = new HashMap<>();
map.put("key1", "value1");
map.put("results", somePOJO);
return map;
}
You can try using the ReadDir function in the io/ioutil
package. Per the docs:
ReadDir reads the directory named by dirname and returns a list of sorted directory entries.
The resulting slice contains os.FileInfo
types, which provide the methods listed here. Here is a basic example that lists the name of everything in the current directory (folders are included but not specially marked - you can check if an item is a folder by using the IsDir()
method):
package main
import (
"fmt"
"io/ioutil"
"log"
)
func main() {
files, err := ioutil.ReadDir("./")
if err != nil {
log.Fatal(err)
}
for _, f := range files {
fmt.Println(f.Name())
}
}
I'd like to offer an alternative that appears to perform at least 10% faster than craigdfrench's answer in my tests (.NET 4.7.2):
public static string GetMD5Hash(string text)
{
using ( var md5 = MD5.Create() )
{
byte[] computedHash = md5.ComputeHash( Encoding.UTF8.GetBytes(text) );
return new System.Runtime.Remoting.Metadata.W3cXsd2001.SoapHexBinary(computedHash).ToString();
}
}
If you prefer to have using System.Runtime.Remoting.Metadata.W3cXsd2001;
at the top, the method body can be made an easier to read one-liner:
using ( var md5 = MD5.Create() )
{
return new SoapHexBinary( md5.ComputeHash( Encoding.UTF8.GetBytes(text) ) ).ToString();
}
Obvious enough, but for completeness, in OP's context it would be used as:
sSourceData = "MySourceData";
tmpHash = GetMD5Hash(sSourceData);
For passing multiple parameters you can cast the string by concatenating it with the ASCII value. Like, for single quotes we can use '
:
var str = "'" + str + "'";
The same parameter you can pass to the onclick()
event. In most of the cases it works with every browser.
Just use
File.Copy(filepath, "\\\\192.168.1.28\\Files");
A windows fileshare exposed via a UNC path is treated as part of the file system, and has nothing to do with the web.
The credentials used will be that of the ASP.NET worker process, or any impersonation you've enabled. If you can tweak those to get it right, this can be done.
You may run into problems because you are using the IP address instead of the server name (windows trust settings prevent leaving the domain - by using IP you are hiding any domain details). If at all possible, use the server name!
If this is not on the same windows domain, and you are trying to use a different domain account, you will need to specify the username as "[domain_or_machine]\[username]"
If you need to specify explicit credentials, you'll need to look into coding an impersonation solution.

AGSM's answer shows a convenient way of solving this problem using the python-dateutil
package. But what if you don't want to install that package? You could solve the problem in vanilla Python like this:
from datetime import date
def add_years(d, years):
"""Return a date that's `years` years after the date (or datetime)
object `d`. Return the same calendar date (month and day) in the
destination year, if it exists, otherwise use the following day
(thus changing February 29 to March 1).
"""
try:
return d.replace(year = d.year + years)
except ValueError:
return d + (date(d.year + years, 1, 1) - date(d.year, 1, 1))
If you want the other possibility (changing February 29 to February 28) then the last line should be changed to:
return d + (date(d.year + years, 3, 1) - date(d.year, 3, 1))
Based on the ObjectDumper of the LINQ samples I created a version that dumps each of the properties on its own line.

Had same problem with psql via command line connecting and pgAdmin not connecting on RDS with AWS. I did have my RDS set to Publicly Accessible. I made sure my ACL and security groups were wide open and still problem so, I did the following:
sudo find . -name *.conf
then sudo nano ./data/pg_hba.conf
then added to top of directives in pg_hba.conf file host all all 0.0.0.0/0 md5
and pgAdmin automatically logged me in.
This also worked in pg_hba.conf file
host all all md5
without any IP address and this also worked with my IP address host all all <myip>/32 md5
As a side note, my RDS was in my default VPC. I had an identical RDS instance in my non-default VPC with identical security group, ACL and security group settings to my default VPC and I could not get it to work. Not sure why but, that's for another day.
find supports wildcard matches, just add a *

compare_rows <- a1$a %fin% a2$a
# the %fin% function comes from the `fastmatch` package
added_rows <- a1[which(compare_rows == FALSE)]
added_rows
# a b

Suppose you have a List Collection containing many items to show in a ListView, take the following example that iterates through the List Collection:
foreach (Inspection inspection in anInspector.getInspections())
{
ListViewItem item = new ListViewItem();
item.Text=anInspector.getInspectorName().ToString();
item.SubItems.Add(inspection.getInspectionDate().ToShortDateString());
item.SubItems.Add(inspection.getHouse().getAddress().ToString());
item.SubItems.Add(inspection.getHouse().getValue().ToString("C"));
listView1.Items.Add(item);
}
That code produces the following output in the ListView (of course depending how many items you have in the List Collection):
Basically the first column is a listviewitem containing many subitems (other columns). It may seem strange but listview is very flexible, you could even build a windows-like file explorer with it!
If the previous answers do not solve your problem, check the source of the data that won't print/convert properly.
In my case, I was using json.load

I was having the same issue, after reverting back also I was not seeing old code. After running the above command I got a clean old version code.
Check out perlfaq4: How do I merge two hashes. There is a lot of good information already in the Perl documentation and you can have it right away rather than waiting for someone else to answer it. :)
Before you decide to merge two hashes, you have to decide what to do if both hashes contain keys that are the same and if you want to leave the original hashes as they were.
If you want to preserve the original hashes, copy one hash (%hash1) to a new hash (%new_hash), then add the keys from the other hash (%hash2 to the new hash. Checking that the key already exists in %new_hash gives you a chance to decide what to do with the duplicates:
my %new_hash = %hash1; # make a copy; leave %hash1 alone
foreach my $key2 ( keys %hash2 )
{
if( exists $new_hash{$key2} )
{
warn "Key [$key2] is in both hashes!";
# handle the duplicate (perhaps only warning)
...
next;
}
else
{
$new_hash{$key2} = $hash2{$key2};
}
}
If you don't want to create a new hash, you can still use this looping technique; just change the %new_hash to %hash1.
foreach my $key2 ( keys %hash2 )
{
if( exists $hash1{$key2} )
{
warn "Key [$key2] is in both hashes!";
# handle the duplicate (perhaps only warning)
...
next;
}
else
{
$hash1{$key2} = $hash2{$key2};
}
}
If you don't care that one hash overwrites keys and values from the other, you could just use a hash slice to add one hash to another. In this case, values from %hash2 replace values from %hash1 when they have keys in common:
@hash1{ keys %hash2 } = values %hash2;
I had the *.pdb
files in the same folder and used the options from Arindam, but it still didn't work. Turns out I needed to enable Enable native code debugging which can be found under Project properties > Debug.
From Eclipsepedia on how to set a conditional breakpoint:
First, set a breakpoint at a given location. Then, use the context menu on the breakpoint in the left editor margin or in the Breakpoints view in the Debug perspective, and select the breakpoint’s properties. In the dialog box, check Enable Condition, and enter an arbitrary Java condition, such as
list.size()==0
. Now, each time the breakpoint is reached, the expression is evaluated in the context of the breakpoint execution, and the breakpoint is either ignored or honored, depending on the outcome of the expression.Conditions can also be expressed in terms of other breakpoint attributes, such as hit count.
Try this:
$new_array = objectToArray($yourObject);
function objectToArray($d)
{
if (is_object($d)) {
// Gets the properties of the given object
// with get_object_vars function
$d = get_object_vars($d);
}
if (is_array($d)) {
/*
* Return array converted to object
* Using __FUNCTION__ (Magic constant)
* for recursive call
*/
return array_map(__FUNCTION__, $d);
} else {
// Return array
return $d;
}
}
Sometimes it's because laravel 5.1 require PHP >= 5.5.9. Update php will solve the problem.
To provide another much simpler solution:-
"Add as link"
Thats it.
If you are using a strongly-typed dataset then you should do this:
If Not ediTransactionRow.Ispay_id1Null Then
'Do processing here
End If
You are getting the error because a strongly-typed data set retrieves the underlying value and exposes the conversion through the property. For instance, here is essentially what is happening:
Public Property pay_Id1 Then
Get
return DirectCast(me.GetValue("pay_Id1", short)
End Get
'Abbreviated for clarity
End Property
The GetValue method is returning DBNull which cannot be converted to a short.
I guess, you didn't insert memory size at the time of creating avd. you can do that by editing the avd.
Java does not allow extending multiple classes.
Let's assume C class is extending A and B classes. Then if suppose A and B classes have method with same name(Ex: method1()). Consider the code:
C obj1 = new C();
obj1.method1();
- here JVM will not understand to which method it need to access. Because both A and B classes have this method. So we are putting JVM in dilemma, so that is the reason why multiple inheritance is removed from Java. And as said implementing multiple classes will resolve this issue.
Hope this has helped.
Even if that topic is quite old, I'd like to add something.
If you overwrite equals
for you classes, so it compares your getId
, you can use:
customer = new Customer(id);
customers.get(customers.indexOf(customer));
Of course, you'd have to check for an IndexOutOfBounds
-Exception, which oculd be translated into a null pointer or a custom CustomerNotFoundException
.
In case you are already using jQuery:
var $body = $('body');
$body.on('mousedown', function (evt) {
$body.on('mouseup mousemove', function handler(evt) {
if (evt.type === 'mouseup') {
// click
} else {
// drag
}
$body.off('mouseup mousemove', handler);
});
});
In most regex implementations (including Java's), :
has no special meaning, neither inside nor outside a character class.
Your problem is most likely due to the fact the -
acts as a range operator in your class:
[A-Za-z0-9.,-:]*
where ,-:
matches all ascii characters between ','
and ':'
. Note that it still matches the literal ':'
however!
Try this instead:
[A-Za-z0-9.,:-]*
By placing -
at the start or the end of the class, it matches the literal "-"
. As mentioned in the comments by Keoki Zee, you can also escape the -
inside the class, but most people simply add it at the end.
A demo:
public class Test {
public static void main(String[] args) {
System.out.println("8:".matches("[,-:]+")); // true: '8' is in the range ','..':'
System.out.println("8:".matches("[,:-]+")); // false: '8' does not match ',' or ':' or '-'
System.out.println(",,-,:,:".matches("[,:-]+")); // true: all chars match ',' or ':' or '-'
}
}
Generally, the backtrace is used to get the stack of the current thread, but if there is a necessity to get the stack trace of all the threads, use the following command.

One option is to put the subquery in a LEFT JOIN
:
select sum ( t.graduates ) - t1.summedGraduates
from table as t
left join
(
select sum ( graduates ) summedGraduates, id
from table
where group_code not in ('total', 'others' )
group by id
) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates
Perhaps a better option would be to use SUM
with CASE
:
select sum(case when group_code = 'total' then graduates end) -
sum(case when group_code not in ('total','others') then graduates end)

from https://docs.microsoft.com/en-us/azure/architecture/guide/architecture-styles/n-tier
An N-tier architecture divides an application tires into logical tiresand physical tiers mainly and their are divide to sub parts.
Layers are a way to separate responsibilities and manage dependencies. Each layer has a specific responsibility. A higher layer can use services in a lower layer, but not the other way around.
Tiers are physically separated, running on separate machines. A tier can call to another tier directly, or use asynchronous messaging (message queue). Although each layer might be hosted in its own tier, that's not required. Several layers might be hosted on the same tier. Physically separating the tiers improves scalability and resiliency, but also adds latency from the additional network communication.
A traditional three-tier application has a presentation tier, a middle tier, and a database tier. The middle tier is optional. More complex applications can have more than three tiers. The diagram above shows an application with two middle tiers, encapsulating different areas of functionality.
An N-tier application can have a closed layer architecture or an open layer architecture:
In a closed layer architecture, a layer can only call the next layer immediately down.
In an open layer architecture, a layer can call any of the layers below it.
A closed layer architecture limits the dependencies between layers. However, it might create unnecessary network traffic, if one layer simply passes requests along to the next layer.
You need to use the ui.item.label (the text) and ui.item.value (the id) properties
$('#selector').autocomplete({
source: url,
select: function (event, ui) {
$("#txtAllowSearch").val(ui.item.label); // display the selected text
$("#txtAllowSearchID").val(ui.item.value); // save selected id to hidden input
}
});
$('#button').click(function() {
alert($("#txtAllowSearchID").val()); // get the id from the hidden input
});
[Edit] You also asked how to create the multi-dimensional array...
You should be able create the array like so:
var $local_source = [[0,"c++"], [1,"java"], [2,"php"], [3,"coldfusion"],
[4,"javascript"], [5,"asp"], [6,"ruby"]];
Read more about how to work with multi-dimensional arrays here: http://www.javascriptkit.com/javatutors/literal-notation2.shtml
I'm always running tests against an in-memory DB (HSQLDB or Derby) for these reasons:
The in-memory DB is loaded with fresh data once the tests start and after most tests, I invoke ROLLBACK to keep it stable. ALWAYS keep the data in the test DB stable! If the data changes all the time, you can't test.
The data is loaded from SQL, a template DB or a dump/backup. I prefer dumps if they are in a readable format because I can put them in VCS. If that doesn't work, I use a CSV file or XML. If I have to load enormous amounts of data ... I don't. You never have to load enormous amounts of data :) Not for unit tests. Performance tests are another issue and different rules apply.
Most of the time when this happens it is bad data in the SQL column. This is the proper way to insert into an image column:
INSERT INTO [TableX] (ImgColumn) VALUES (
(SELECT * FROM OPENROWSET(BULK N'C:\....\Picture 010.png', SINGLE_BLOB) as tempimg))
Most people do it incorrectly this way:
INSERT INTO [TableX] (ImgColumn) VALUES ('C:\....\Picture 010.png'))
If you use Dreamweaver you could easily note to unclosed div. In the left pane of the code view you can see there <>
highlight invalid code
button, click this button and you will notice the unclosed div highlighted and then close your unclosed div. Press F5 to refresh the page to see that any other unclosed div are there.
You can also validate your page in Dreamweaver too. File>Check Page>Browser Compatibility
, then task-pane will appear Click on Validation
, on the left side there you'll see ? button click this to validate.
Enjoy!
Oracle would be
SELECT NVL(MAX(X), 0) AS MaxX

You can loop to create the String
List<String> list = new ArrayList<String>();
for (int i=0; i<jsonArray.length(); i++) {
list.add( jsonArray.getString(i) );
}
String[] stringArray = list.toArray(new String[list.size()]);

that enables you to list the devices available in the local process. (N.B. As an undocumented method, this is subject to backwards incompatible changes.) The function returns a list of DeviceAttributes
protocol buffer objects. You can extract a list of string device names for the GPU devices as follows:
from tensorflow.python.client import device_lib
def get_available_gpus():
local_device_protos = device_lib.list_local_devices()
return [x.name for x in local_device_protos if x.device_type == 'GPU']
Note that (at least up to TensorFlow 1.4), calling device_lib.list_local_devices()
will run some initialization code that, by default, will allocate all of the GPU memory on all of the devices (GitHub issue). To avoid this, first create a session with an explicitly small per_process_gpu_fraction
, or allow_growth=True
, to prevent all of the memory being allocated. See this question for more details.
you can use following CSS code..

The PowerShell string evaluation is calling ToString() on the DataSet. In order to evaluate any properties (or method calls), you have to force evaluation by enclosing the expression in $()
for($i=0;$i -lt $ds.Tables[1].Rows.Count;$i++)
{
write-host "value is : $i $($ds.Tables[1].Rows[$i][0])"
}
Additionally foreach
allows you to iterate through a collection or array without needing to figure out the length.
Rewritten (and edited for compile) -
foreach ($Row in $ds.Tables[1].Rows)
{
write-host "value is : $($Row[0])"
}
Of course that works; when @item1 = N''
, it IS NOT NULL
.
You can define @item1
as NULL
by default at the top of your stored procedure, and then not pass in a parameter.
The explanation for how it works:
JUnit wraps your test method in a Statement object so statement and Execute()
runs your test. Then instead of calling statement.Execute()
directly to run your test, JUnit passes the Statement to a TestRule with the @Rule
annotation. The TestRule's "apply" function returns a new Statement given the Statement with your test. The new Statement's Execute()
method can call the test Statement's execute method (or not, or call it multiple times), and do whatever it wants before and after
.
Now, JUnit has a new Statement that does more than just run the test, and it can again pass that to any more rules before finally calling Execute.

prevent arrow only available for any object else SELECT, well actually i haven't tes on another object LOL. but it can stop arrow event on page and input type.
i already try to block arrow left and right to change the value of SELECT object using "e.preventDefault()" or "return false" on "kepress" "keydown" and "keyup" event but it still change the object value. but the event still tell you that arrow was pressed.

Do you have access to your database, if so just open it up and look up the column and use an SQL call to retrieve the needed.
A short example on a form to retrieve data from a database table:
Form contain only a GataGridView named DataGrid
Database name: DB.mdf
Table name: DBtable
Column names in table: Name as varchar(50), Age as int, Gender as bit.
Private Sub DatabaseTest_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
Public ConString As String = "Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\{username}\documents\visual studio 2010\Projects\Userapplication prototype v1.0\Userapplication prototype v1.0\Database\DB.mdf;" & "Integrated Security=True;User Instance=True"
Dim conn As New SqlClient.SqlConnection
Dim cmd As New SqlClient.SqlCommand
Dim da As New SqlClient.SqlDataAdapter
Dim dt As New DataTable
Dim sSQL As String = String.Empty
Try
conn = New SqlClient.SqlConnection(ConString)
conn.Open() 'connects to the database
cmd.Connection = conn
cmd.CommandType = CommandType.Text
sSQL = "SELECT * FROM DBtable" 'Sql to be executed
cmd.CommandText = sSQL 'makes the string a command
da.SelectCommand = cmd 'puts the command into the sqlDataAdapter
da.Fill(dt) 'populates the dataTable by performing the command above
Me.DataGrid.DataSource = dt 'Updates the grid using the populated dataTable
'the following is only if any errors happen:
If dt.Rows.Count = 0 Then
MsgBox("No record found!")
End If
Catch ex As Exception
MsgBox(ErrorToString)
Finally
conn.Close() 'closes the connection again so it can be accessed by other users or programs
End Try
End Sub
This will fetch all the rows and columns from your database table for review.
If you want to only fetch the names just change the sql call with: "SELECT Name FROM DBtable" this way the DataGridView will only show the column names.
I'm only a rookie but i would strongly advise to get rid of theses auto generate wizards. Using SQL you have full access to your database and what happens.
Also one last thing, if your database doesn't use SQLClient just change it to OleDB.
Example: "Dim conn As New SqlClient.SqlConnection
" becomes: Dim conn As New OleDb.OleDbConnection
Controller (Example: User.php)
<?php
defined('BASEPATH') or exit('No direct script access allowed');
class Users extends CI_controller
{
// Table
protected $table = 'users';
function index()
{
$data['users'] = $this->model->ra_object($this->table);
$this->load->view('users_list', $data);
}
}
View (Example: users_list.php)
<table>
<thead>
<tr>
<th>Name</th>
<th>Surname</th>
</tr>
</thead>
<tbody>
<?php foreach($users as $user) : ?>
<tr>
<td><?php echo $user->name; ?></td>
<td><?php echo $user->surname; ?></th>
</tr>
<?php endforeach; ?>
</tbody>
</table>

catch function in your api should either return some data which could be handled by Api call in React class or throw new error which should be caught using a catch function in your React class code. Latter approach should be something like:
return fetch(url)
.then(function(response){
return response.json();
})
.then(function(json){
return {
city: json.name,
temperature: kelvinToF(json.main.temp),
description: _.capitalize(json.weather[0].description)
}
})
.catch(function(error) {
console.log('There has been a problem with your fetch operation: ' + error.message);
// ADD THIS THROW error
throw error;
});
Then in your React Class:
Api(region.latitude, region.longitude)
.then((data) => {
console.log(data);
this.setState(data);
}).catch((error)=>{
console.log("Api call error");
alert(error.message);
});

Here's the link that gives me the answer:
[Install] the "fake sendmail for windows". If you are not using XAMPP you can download it here: http://glob.com.au/sendmail/sendmail.zip
[Modify] the php.ini file to use it (commented out the other lines): [mail function] ; For Win32 only. ; SMTP = smtp.gmail.com ; smtp_port = 25 ; For Win32 only. ; sendmail_from = <e-mail username>@gmail.com ; For Unix only. You may supply arguments as well (default: "sendmail -t -i"). sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"
(ignore the "Unix only" bit, since we actually are using sendmail)
You then have to configure the "sendmail.ini" file in the directory where sendmail was installed:
[sendmail] smtp_server=smtp.gmail.com smtp_port=25 error_logfile=error.log debug_logfile=debug.log auth_username=<username> auth_password=<password> force_sender=<e-mail username>@gmail.com
To access a Gmail account protected by 2-factor verification, you will need to create an application-specific password. (source)
Try this:

}
}
}
You can do
[5, 10].min
or
[4, 7].max
They come from the Enumerable module, so anything that includes Enumerable
will have those methods available.
v2.4 introduces own Array#min
and Array#max
, which are way faster than Enumerable's methods because they skip calling #each
.
@nicholasklick mentions another option, Enumerable#minmax
, but this time returning an array of [min, max]
.
[4, 5, 7, 10].minmax
=> [4, 10]
Make sure you specify pass header=None
and add usecols=[3,6]
for the 4th and 7th columns.
Can't tell you how many times this has caught. me.

This is an old question, but is still regularly viewed/needed. I want to post to caution readers like me that whitespace as mentioned in the OP's question is not the same as Regex's definition, to include newlines, tabs, and space characters -- Git asks you to be explicit. See some options here: https://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration
As stated, git diff -b
or git diff --ignore-space-change
will ignore spaces at line ends. If you desire that setting to be your default behavior, the following line adds that intent to your .gitconfig file, so it will always ignore the space at line ends:
git config --global core.whitespace trailing-space
In my case, I found this question because I was interested in ignoring "carriage return whitespace differences", so I needed this:
git diff --ignore-cr-at-eol
or
git config --global core.whitespace cr-at-eol
from here.
You can also make it the default only for that repo by omitting the --global parameter, and checking in the settings file for that repo. For the CR problem I faced, it goes away after check-in if warncrlf or autocrlf = true in the [core] section of the .gitconfig file.
I am surprised nobody mentioned regex because sometimes string must be prepared and normalized before casting to number
import re
def parseNumber(value, as_int=False):
try:
number = float(re.sub('[^.\-\d]', '', value))
if as_int:
return int(number + 0.5)
else:
return number
except ValueError:
return float('nan') # or None if you wish
usage:
parseNumber('13,345')
> 13345.0
parseNumber('- 123 000')
> -123000.0
parseNumber('99999\n')
> 99999.0
and by the way, something to verify you have a number:
import numbers
def is_number(value):
return isinstance(value, numbers.Number)
# will work with int, float, long, Decimal
I found the same thing: curl by itself would print to STDOUT, but could not be piped into another program.
At first, I thought I had solved it by using xargs to echo the output first:
curl -s ... <url> | xargs -0 echo | ...
But then, as pointed out in the comments, it also works without the xargs part, so -s
(silent mode) is the key to preventing extraneous progress output to STDOUT:
curl -s ... <url> | perl -ne 'print $1 if /<sometag>([^<]+)/'
The above example grabs the simple <sometag>
content (containing no embedded tags) from the XML output of the curl statement.
Here's my much shorter implementation:
Object.unflatten = function(data) {
"use strict";
if (Object(data) !== data || Array.isArray(data))
return data;
var regex = /\.?([^.\[\]]+)|\[(\d+)\]/g,
resultholder = {};
for (var p in data) {
var cur = resultholder,
prop = "",
m;
while (m = regex.exec(p)) {
cur = cur[prop] || (cur[prop] = (m[2] ? [] : {}));
prop = m[2] || m[1];
}
cur[prop] = data[p];
}
return resultholder[""] || resultholder;
};
flatten
hasn't changed much (and I'm not sure whether you really need those isEmpty
cases):
Object.flatten = function(data) {
var result = {};
function recurse (cur, prop) {
if (Object(cur) !== cur) {
result[prop] = cur;
} else if (Array.isArray(cur)) {
for(var i=0, l=cur.length; i<l; i++)
recurse(cur[i], prop + "[" + i + "]");
if (l == 0)
result[prop] = [];
} else {
var isEmpty = true;
for (var p in cur) {
isEmpty = false;
recurse(cur[p], prop ? prop+"."+p : p);
}
if (isEmpty && prop)
result[prop] = {};
}
}
recurse(data, "");
return result;
}
Together, they run your benchmark in about the half of the time (Opera 12.16: ~900ms instead of ~ 1900ms, Chrome 29: ~800ms instead of ~1600ms).

I have found that the Worksheet ".UsedRange" method is superior in many instances to solve this problem. I struggled with a truncation issue that is a normal behaviour of the ".CurrentRegion" method. Using [ Worksheets("Sheet1").Range("A1").CurrentRegion ] does not yield the results I desired when the worksheet consists of one column with blanks in the rows (and the blanks are wanted). In this case, the ".CurrentRegion" will truncate at the first record. I implemented a work around but recently found an even better one; see code below that allows copying the whole set to another sheet or to identify the actual address (or just rows and columns):
Sub mytest_GetAllUsedCells_in_Worksheet()
Dim myRange
Set myRange = Worksheets("Sheet1").UsedRange
'Alternative code: set myRange = activesheet.UsedRange
'use msgbox or debug.print to show the address range and counts
MsgBox myRange.Address
MsgBox myRange.Columns.Count
MsgBox myRange.Rows.Count
'Copy the Range of data to another sheet
'Note: contains all the cells with that are non-empty
myRange.Copy (Worksheets("Sheet2").Range("A1"))
'Note: transfers all cells starting at "A1" location.
' You can transfer to another area of the 2nd sheet
' by using an alternate starting location like "C5".
End Sub

With that row
var element = {};
you define element
to be a plain object. The native JavaScript object has no push()
method. To add new items to a plain object use this syntax:
element[ yourKey ] = yourValue;
On the other hand you could define element
as an array using
var element = [];
Then you can add elements using push()
.
This worked for me:
driver.findElement(yourElement).clear();
driver.findElement(yourelement).sendKeys("");
Okay, how about a CSS answer! We use display: table
. Then each of the divs are rows, and finally we apply height of 100% to middle 'row' and voilà.
body { display: table; }
div { display: table-row; }
#content {
width:450px;
margin:0 auto;
text-align: center;
background-color: blue;
color: white;
height: 100%;
}
You may also consider the following solution:
let sum = options.set0.concat(options.set1);
const codeHTML = '<ol>' + sum.reduce((html, item) => {
return html + "<li>" + item + "</li>";
}, "") + '</ol>';
document.querySelector("#list").innerHTML = codeHTML;

I never had any issues with this project because I had TypeScript installed as a global module. As this project didn't include TypeScript as a dev dependency (and expected it to be installed as global), I had the error when testing in another machine (without TypeScript) and running npm install
didn't fix the problem. So I had to include TypeScript as a dev dependency (npm install typescript --save-dev
) to solve the problem.

If you write down a fractional value like 1 / 7
as decimal value you get
1/7 = 0.142857142857142857142857142857142857142857...
with an infinite sequence of 142857
. Since you can only write a finite number of digits you will inevitably introduce a rounding (or truncation) error.
Numbers like 1/10
or 1/100
expressed as binary numbers with a fractional part also have an infinite number of digits after the decimal point:
1/10 = binary 0.0001100110011001100110011001100110...
Doubles
store values as binary and therefore might introduce an error solely by converting a decimal number to a binary number, without even doing any arithmetic.
Decimal numbers (like BigDecimal
), on the other hand, store each decimal digit as is (binary coded, but each decimal on its own). This means that a decimal type is not more precise than a binary floating point or fixed point type in a general sense (i.e. it cannot store 1/7
without loss of precision), but it is more accurate for numbers that have a finite number of decimal digits as is often the case for money calculations.
Java's BigDecimal
has the additional advantage that it can have an arbitrary (but finite) number of digits on both sides of the decimal point, limited only by the available memory.
Yes you can: Take this utility function that I have written today:
function shangMergeCol() {
tcol= db.getCollection(arguments[0]);
for (var i=1; i<arguments.length; i++){
scol= db.getCollection(arguments[i]);
scol.find().forEach(
function (d) {
tcol.insert(d);
}
)
}
}
You can pass to this function any number of collections, the first one is going to be the target one. All the rest collections are sources to be transferred to the target one.

New in Django 1.7 is a app registry that stores configuration and provides introspection. This machinery let's you change several app attributes.
The main point I want to make is that renaming an app isn't always necessary: With app configuration it is possible to resolve conflicting apps. But also the way to go if your app needs friendly naming.
As an example I want to name my polls app 'Feedback from users'. It goes like this:
Create a apps.py
file in the polls
directory:
from django.apps import AppConfig
class PollsConfig(AppConfig):
name = 'polls'
verbose_name = "Feedback from users"
Add the default app config to your polls/__init__.py
:
default_app_config = 'polls.apps.PollsConfig'
For more app configuration: https://docs.djangoproject.com/en/1.7/ref/applications/

Try using this:
$(".move_to").on("click", function(e){
e.preventDefault();
$('#contactsForm').attr('action', "/test1").submit();
});
Moving the order in which you use .preventDefault()
might fix your issue. You also didn't use function(e)
so e.preventDefault();
wasn't working.
Here it is working: http://jsfiddle.net/TfTwe/1/ - first of all, click the 'Check action attribute.' link. You'll get an alert saying undefined
. Then click 'Set action attribute.' and click 'Check action attribute.' again. You'll see that the form's action attribute has been correctly set to /test1
.
There are dozens of open-source libraries available that you can use to making an HTTP POST request in Node.
const axios = require('axios');
const data = {
name: 'John Doe',
job: 'Content Writer'
};
axios.post('https://reqres.in/api/users', data)
.then((res) => {
console.log(`Status: ${res.status}`);
console.log('Body: ', res.data);
}).catch((err) => {
console.error(err);
});
const needle = require('needle');
const data = {
name: 'John Doe',
job: 'Content Writer'
};
needle('post', 'https://reqres.in/api/users', data, {json: true})
.then((res) => {
console.log(`Status: ${res.statusCode}`);
console.log('Body: ', res.body);
}).catch((err) => {
console.error(err);
});
const request = require('request');
const options = {
url: 'https://reqres.in/api/users',
json: true,
body: {
name: 'John Doe',
job: 'Content Writer'
}
};
request.post(options, (err, res, body) => {
if (err) {
return console.log(err);
}
console.log(`Status: ${res.statusCode}`);
console.log(body);
});
const https = require('https');
const data = JSON.stringify({
name: 'John Doe',
job: 'Content Writer'
});
const options = {
hostname: 'reqres.in',
path: '/api/users',
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Content-Length': data.length
}
};
const req = https.request(options, (res) => {
let data = '';
console.log('Status Code:', res.statusCode);
res.on('data', (chunk) => {
data += chunk;
});
res.on('end', () => {
console.log('Body: ', JSON.parse(data));
});
}).on("error", (err) => {
console.log("Error: ", err.message);
});
req.write(data);
req.end();

The file you are editing has been edited with some other editor that does not use the same line endings, resulting in a file with mixed line endings.
The ASCII characters in use for line endings are:
CR, Carriage Return
LF, Line Feed
Windows = CRLF
Mac OS 9 or earlier = CR
Unix = LF
In my case, I only updated the custom view.
// DO NOT LIKE THIS
customView.layoutIfNeeded() // Change to view.layoutIfNeeded()
UIView.animate(withDuration: 0.5) {
customViewConstraint.constant = 100.0
customView.layoutIfNeeded() // Change to view.layoutIfNeeded()
}
A different perspective to the same problem away from Javascript and using php:
<a data-toggle="modal" href="#myModal">LINK</a>
<div class="modal fade" tabindex="-1" aria-labelledby="gridSystemModalLabel" id="myModal" role="dialog" style="max-width: 90%;">
<div class="modal-dialog" style="text-align: left;">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Title</h4>
</div>
<div class="modal-body">
<?php include( 'remotefile.php'); ?>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
and put in the remote.php file your basic html source.
mysql -u <USERNAME> -p <DB NAME> < <dump file path>
-u
- for Username
-p
- to prompt the Password
Eg. mysql -u root -p mydb < /home/db_backup.sql
You can also provide password preceded by -p but for the security reasons it is not suggestible. The password will appear on the command itself rather masked.
You could just do:
var canvas = yourCanvasElement;
var mouseX = (event.clientX - (canvas.offsetLeft - canvas.scrollLeft)) - 2;
var mouseY = (event.clientY - (canvas.offsetTop - canvas.scrollTop)) - 2;
This will give you the exact position of the mouse pointer.
