Also, in some cases is important to check the target folder permissions. To give write permission for the user might be the solution. That worked for me.
I had the same issue, To resolved this i had checked/done several things
What Didn't work
1) Read/write permissions were given to directory
2) Restarted visual studio
3) Tried deleting visual studio temp files
What worked at last
Just paste the command given by Fred Morrison into the "Package Manager Console":
Get-Process | Where-Object -Property Name -EQ 'VBCSCompiler' | Stop-Process -Force -Verbose
Note: Just an observation Restarting Visual studio might not work in this case but restarting system can because stoppin process "VBCSCompiler" was the solution so we can do it either way.
I created copy of my inet folder, to make a duplicate of the site. It showed 'access denied .../App_Data/viewstate/1/6/6/0 ... '. On checking it showed that app_data folder is having IIS_IUSER addes but does not have modify or write acess checked. Just check those boxes and the instance begin to run.
I used Jason's answer but wanted to clarify how to get in to properties.
You do not have permissions to access the file. Please be sure whether you can access the file in that drive.
string route= @"E:\Sample.text";
FileStream fs = new FileStream(route, FileMode.Create);
You have to provide the file name to create. Please try this, now you can create.
From what you've said so far, it sounds like a problem where the MySQL driver in PHP5.3 has trouble connecting to the older MySQL version 4.1. Have a look on http://www.bitshop.com/Blogs/tabid/95/EntryId/67/PHP-mysqlnd-cannot-connect-to-MySQL-4-1-using-old-authentication.aspx
There's a similar question here with some useful answers, Cannot connect to MySQL 4.1+ using old authentication
SELECT `User`, `Host`, Length(`Password`) FROM mysql.user
This will return 16 for accounts with old passwords and 41 for accounts with new passwords (and 0 for accounts with no password at all, you might want to take care of those as well). Either use the user managements tools of the MySQL front end (if there are any) or
SET PASSWORD FOR 'User'@'Host'=PASSWORD('yourpassword');

First I tried this https://python-forum.io/Thread-All-pip-install-attempts-are-met-with-SSL-error#pid_28035 ,but seems it couldn't solve my problems,and still repeat the same issue.
And Second if you are working on a business computer,generally it may exist a web content filter(but I can access https://pypi.python.org through browser directly).And solve this issue by adding a proxy server.
For windows,open the Internet properties
through IE or Chrome or whatsoever ,then set valid proxy address and port,and this way solve my problems
Or just adding the option pip --proxy [proxy-address]:port install mitmproxy
.But you always need to add this option while installing by pypi
The above two solution is alternative for you demand.
Not the answer for this question
I got this exception when trying to delete a folder where i deleted the file inside.
Example:
createFolder("folder");
createFile("folder/file");
deleteFile("folder/file");
deleteFolder("folder"); // error here
While deleteFile("folder/file");
returned that it was deleted, the folder will only be considered empty after the program restart.
On some operating systems it may not be possible to remove a file when it is open and in use by this Java virtual machine or other programs.
https://docs.oracle.com/javase/8/docs/api/java/nio/file/Files.html#delete-java.nio.file.Path-
I had similar problems because my password contains ";" char breaking my password when I creates it at first moment. Caution with this if can help you.
In the eclipse environment where you execute your java programs, take the following steps:
The SQL Server service account does not have permissions to write to the folder C:\Users\Kimpoy\Desktop\Backup\
For a different command I decided to change the network from public to work.
After trying to use the psexec command again it worked again.
So to get psexec to work try to change your network type from public to work or home.
Tried most of the above with no joy. Looking at my password, it had characters that might confuse a parser. I wrapped the password in quotes and the error was resolved. -p"a:@#$%^&+6>&FAEH"

A call to EntityManager.flush();
will force the data to be persist in the database immediately as EntityManager.persist()
will not (depending on how the EntityManager is configured : FlushModeType (AUTO or COMMIT) by default it's set to AUTO and a flush will be done automatically by if it's set to COMMIT the persitence of the data to the underlying database will be delayed when the transaction is commited).
Problem: Copying multiple directories from remote server to local machine using a single SCP command and retaining each directory as it is in the remote server.
Solution: SCP can do this easily. This solves the annoying problem of entering password multiple times when using SCP with multiple folders. Consequently, this also saves a lot of time!
e.g.
# copies folders t1, t2, t3 from `test` to your local working directory
# note that there shouldn't be any space in between the folder names;
# we also escape the braces.
# please note the dot at the end of the SCP command
~$ cd ~/working/directory
~$ scp -r [email protected]:/work/datasets/images/test/\{t1,t2,t3\} .
PS: Motivated by this great answer: scp or sftp copy multiple files with single command
Based on the comments, this also works fine in Git Bash on Windows
If you have VS 2013, you have to go to: %LOCALAPPDATA%\Microsoft\VisualStudio\12.0 then rename the ComponentModelCache folder.
SQL Server requires a transaction log in order to function.
That said there are two modes of operation for the transaction log:
In Full mode the transaction log keeps growing until you back up the database. In Simple mode: space in the transaction log is 'recycled' every Checkpoint.
Very few people have a need to run their databases in the Full recovery model. The only point in using the Full model is if you want to backup the database multiple times per day, and backing up the whole database takes too long - so you just backup the transaction log.
The transaction log keeps growing all day, and you keep backing just it up. That night you do your full backup, and SQL Server then truncates the transaction log, begins to reuse the space allocated in the transaction log file.
If you only ever do full database backups, you don't want the Full recovery mode.
:nth-last-child(-n+2)
should do the trick
If you have both 2.7 and 3.x versions of python installed, then just rename the python exe file of python 3.x version to something like - "python.exe" to "python3.exe". Now you can use pip for both versions individually. If you normally type "pip install " it will consider the 2.7 version by default. If you want to install it on the 3.x version you need to call the command as "python3 -m pip install ".
easy way is:
a = [1,2]
d = {}
for i in a:
d[i]=[i, ]
print(d)
{'1': [1, ], '2':[2, ]}
Use the Below Code for that
UPDATE Table1 SET Column1 = LTRIM(RTRIM(REPLACE(REPLACE(REPLACE(Column1, CHAR(9), ''), CHAR(10), ''), CHAR(13), '')))`
you could write a simple function like the following:
public static MyGender ConvertTo(TheirGender theirGender)
{
switch(theirGender)
{
case TheirGender.Male:
break;//return male
case TheirGender.Female:
break;//return female
case TheirGender.Unknown:
break;//return whatever
}
}
Text editors have an amazing feature called search and replace. You don't say what editor you use, but since shell scripts tend to be *nix, and I use VI, here's the command to comment lines 20 to 50 of some shell script:

The difference between this two tables ItemBack1
and #ItemBack1
is that the first on is persistent (permanent) where as the other is temporary.
Now if take a look at your question again
Is it necessary to Use # for creating temp table in sql server?
The answer is Yes, because without this preceding #
the table will not be a temporary table, it will be independent of all sessions and scopes.

Interfaces and base classes represent two different forms of relationships.
Inheritance (base classes) represent an "is-a" relationship. E.g. a dog or a cat "is-a" pet. This relationship always represents the (single) purpose of the class (in conjunction with the "single responsibility principle").
Interfaces, on the other hand, represent additional features of a class. I'd call it an "is" relationship, like in "Foo
is disposable", hence the IDisposable
interface in C#.
You need to implement a custom Authenticator
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
class GMailAuthenticator extends Authenticator {
String user;
String pw;
public GMailAuthenticator (String username, String password)

super();
this.user = username;
this.pw = password;
}
public PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(user, pw);

Here is some SQL that actually make sense:

Simple is always better.
One more answer for this. I'm posting a separate answer, because it's more of an "exact" attempt at a solution than a list of possible solutions:
Here's a filter that will do an "immediate if" (aka iif):
app.filter('iif', function () {
return function(input, trueValue, falseValue) {
return input ? trueValue : falseValue;
};
});
and can be used like this:
{{foo == "bar" | iif : "it's true" : "no, it's not"}}
new = text[:1] + 'Z' + text[2:]
I have a simple way to serialize an object to XML using C#, it works great and it's highly reusable. I know this is an older thread, but I wanted to post this because someone may find this helpful to them.
Here is how I call the method:
var objectToSerialize = new MyObject();
var xmlString = objectToSerialize.ToXmlString();
Here is the class that does the work:
Note: Since these are extension methods they need to be in a static class.
using System.IO;
using System.Xml.Serialization;
public static class XmlTools
{
public static string ToXmlString<T>(this T input)
{
using (var writer = new StringWriter())
{
input.ToXml(writer);
return writer.ToString();
}
}
private static void ToXml<T>(this T objectToSerialize, StringWriter writer)
{
new XmlSerializer(typeof(T)).Serialize(writer, objectToSerialize);
}
}
I was readying this solutions and this example may help.
My database have two tables (email and credit_card) with primary keys for their IDs. Another table (client) refers to this tables IDs as foreign keys. I have a reason to have the email apart from the client data.
First I insert the row data for the referenced tables (email, credit_card) then you get the ID for each, those IDs are needed in the third table (client).
If you don't insert first the rows in the referenced tables, MySQL wont be able to make the correspondences when you insert a new row in the third table that reference the foreign keys.
If you first insert the referenced rows for the referenced tables, then the row that refers to foreign keys, no error occurs.
Hope this helps.
grep
matches, grep -v
does the inverse. If you need to "match A but not B" you usually use pipes:
grep "${PATT}" file | grep -v "${NOTPATT}"
I imagine this like that:

<head>
<script>
var frame_loaded = 0;
function setFrameLoaded()

console.log('iframe loaded')
} else {
console.log('iframe not loaded')
}
})
</script>
</head>
<button id='click'>click me</button>
<iframe id='MainPopupIframe' onload='setFrameLoaded();' src='http://...' />...</iframe>
There are two ways for writing a proper media queries in css. If you are writing media queries for larger device first, then the correct way of writing will be:
@media only screen
and (min-width : 415px){
/* Styles */
}
@media only screen
and (min-width : 769px){
/* Styles */
}
@media only screen
and (min-width : 992px){
/* Styles */
}
But if you are writing media queries for smaller device first, then it would be something like:
@media only screen
and (max-width : 991px){
/* Styles */
}
@media only screen
and (max-width : 768px){
/* Styles */
}
@media only screen
and (max-width : 414px){
/* Styles */
}
process.terminate() doesn't work when using shell=True

One explanation might be floating point rounding issues. For example, if you could call
range(0, 0.4, 0.1)
you might expect an output of
[0, 0.1, 0.2, 0.3]
but you in fact get something like
[0, 0.1, 0.2000000001, 0.3000000001]
due to rounding issues. And since range is often used to generate indices of some sort, it's integers only.
Still, if you want a range generator for floats, you can just roll your own.
def xfrange(start, stop, step):
i = 0
while start + i * step < stop:
yield start + i * step
i += 1
You can do this in Oracle 12.1 or above:
declare
rc sys_refcursor;
begin
open rc for select * from dual;
dbms_sql.return_result(rc);
end;
I don't have DBVisualizer to test with, but that should probably be your starting point.
For more details, see Implicit Result Sets in the Oracle 12.1 New Features Guide, Oracle Base etc.
For earlier versions, depending on the tool you might be able to use ref cursor bind variables like this example from SQL*Plus:
set autoprint on
var rc refcursor
begin
open :rc for select count(*) from dual;
end;
/
PL/SQL procedure successfully completed.
COUNT(*)

Use @title
in your controllers when you want your variable to be available in your views.
The explanation is that @title
is an instance variable while title
is a local variable. Rails makes instance variables from controllers available to views because the template code (erb, haml, etc) is executed within the scope of the current controller instance.
Mysql documentation says : CREATE SCHEMA is a synonym for CREATE DATABASE as of MySQL 5.0.2.
this all goes back to an ANSI standard for SQL in the mid-80s.
That standard had a "CREATE SCHEMA" command, and it served to introduce multiple name spaces for table and view names. All tables and views were created within a "schema". I do not know whether that version defined some cross-schema access to tables and views, but I assume it did. AFAIR, no product (at least back then) really implemented it, that whole concept was more theory than practice.
OTOH, ISTR this version of the standard did not have the concept of a "user" or a "CREATE USER" command, so there were products that used the concept of a "user" (who then had his own name space for tables and views) to implement their equivalent of "schema".
This is an area where systems differ.
As far as administration is concerned, this should not matter too much, because here you have differences anyway.
As far as you look at application code, you "only" have to care about cases where one application accesses tables from multiple name spaces. AFAIK, all systems support a syntax ".", and for this it should not matter whether the name space is that of a user, a "schema", or a "database".
Let me try example
for x in 1 2 3 ; do { echo a $x ; sleep 1 ; echo b $x ; } & done ; sleep 10
And use jobs
to see what's running.
Python has two different ways to convert an object to a string: str()
and repr()
. Printing an object uses str()
; printing a list containing an object uses str()
for the list itself, but the implementation of list.__str__()
calls repr()
for the individual items.
So you should also overwrite __repr__()
. A simple
__repr__ = __str__
at the end of the class body will do the trick.
A of couple things that need to happen...
The view controller needs to extend the type UITableViewDelegate
The view controller needs to include the didSelectRowAt
function.
The table view must have the view controller assigned as its delegate.
Below is one place where assigning the delegate could take place (within the view controller).
override func loadView() {
tableView.dataSource = self
tableView.delegate = self
view = tableView
}
And a simple implementation of the didSelectRowAt
function.
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print("row: \(indexPath.row)")
}
I used (the suggested answer from above)
sudo apt-get install eclipse eclipse-cdt g++
but ONLY after then also doing
sudo eclipse -clean

Since the OP asked about CPU usage AND memory usage (accepted answer only shows technique to get cpu usage), I'd like to recommend the ActivityManager class and specifically the accepted answer from this question: How to get current memory usage in android?
The difference between these two approaches is as follows:
Synchronous way:
It waits for each operation to complete, after that only it executes the next operation.
For your query:
The console.log()
command will not be executed until & unless the query has finished executing to get all the result from Database.
Asynchronous way:
It never waits for each operation to complete, rather it executes all operations in the first GO only. The result of each operation will be handled once the result is available.
For your query:
The console.log()
command will be executed soon after the Database.Query()
method. While the Database query runs in the background and loads the result once it is finished retrieving the data.
Use cases
If your operations are not doing very heavy lifting like querying huge data from DB then go ahead with Synchronous way otherwise Asynchronous way.
In Asynchronous way you can show some Progress indicator to the user while in background you can continue with your heavy weight works. This is an ideal scenario for GUI apps.
There is one way to make an immutable array in Java:
final String[] IMMUTABLE = new String[0];
Arrays with 0 elements (obviously) cannot be mutated.
This can actually come in handy if you are using the List.toArray
method to convert a List
to an array. Since even an empty array takes up some memory, you can save that memory allocation by creating a constant empty array, and always passing it to the toArray
method. That method will allocate a new array if the array you pass doesn't have enough space, but if it does (the list is empty), it will return the array you passed, allowing you to reuse that array any time you call toArray
on an empty List
.
final static String[] EMPTY_STRING_ARRAY = new String[0];
List<String> emptyList = new ArrayList<String>();
return emptyList.toArray(EMPTY_STRING_ARRAY); // returns EMPTY_STRING_ARRAY
You can escape by doubling the quotes
g="abcd """ & a & """"
or write an explicit chr()
call
g="abcd " & chr(34) & a & chr(34)
if you have a dataframe where some columns are numeric and some are other (character or factor) and you only want to do the correlations for the numeric columns, you could do the following:
set.seed(10)
x = as.data.frame(matrix(rnorm(100), ncol = 10))
x$L1 = letters[1:10]
x$L2 = letters[11:20]
cor(x)
Error in cor(x) : 'x' must be numeric
but
cor(x[sapply(x, is.numeric)])

In C, the type of a character constant like 'a'
is actually an int
, with size of 4 (or some other implementation-dependent value). In C++, the type is char
, with size of 1. This is one of many small differences between the two languages.
Below added code is working for me if you are using pattern dd-MM-yyyy.
public boolean isValidDate(String date) {
boolean check;
String date1 = "^(0?[1-9]|[12][0-9]|3[01])-(0?[1-9]|1[012])-([12][0-9]{3})$";
check = date.matches(date1);
return check;
}
I tried this tool and it gave me good results.
In addition to the answer of eldos I also needed gcc
in CentOS 7:
yum install libcurl-devel gcc
We can emulate a do-while loop in Bash with while [[condition]]; do true; done
like this:
while [[ current_time <= $cutoff ]]
check_if_file_present
#do other stuff
do true; done
For an example. Here is my implementation on getting ssh connection in bash script:
#!/bin/bash
while [[ $STATUS != 0 ]]
ssh-add -l &>/dev/null; STATUS="$?"
if [[ $STATUS == 127 ]]; then echo "ssh not instaled" && exit 0;
elif [[ $STATUS == 2 ]]; then echo "running ssh-agent.." && eval `ssh-agent` > /dev/null;
elif [[ $STATUS == 1 ]]; then echo "get session identity.." && expect $HOME/agent &> /dev/null;
else ssh-add -l && git submodule update --init --recursive --remote --merge && return 0; fi
do true; done
It will give the output in sequence as below:
Step #0 - "gcloud": intalling expect..
Step #0 - "gcloud": running ssh-agent..
Step #0 - "gcloud": get session identity..
Step #0 - "gcloud": 4096 SHA256:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX /builder/home/.ssh/id_rsa (RSA)

Finished Step #0 - "gcloud"
Use the Chart Wizard.
On Step 2 of 4, there is a tab labeled "Series". There are 3 fields and a list box on this tab. The list box shows the different series you are already including on the chart. Each series has both a "Name" field and a "Values" field that is specific to that series. The final field is the "Category (X) axis labels" field, which is common to all series.
Click on the "Add" button below the list box. This will add a blank series to your list box. Notice that the values for "Name" and for "Values" change when you highlight a series in the list box.
Select your new series.
There is an icon in each field on the right side. This icon allows you to select cells in the workbook to pull the data from. When you click it, the Wizard temporarily hides itself (except for the field you are working in) allowing you to interact with the workbook.
Select the appropriate sheet in the workbook and then select the fields with the data you want to show in the chart. The button on the right of the field can be clicked to unhide the wizard.
Hope that helps.
EDIT: The above applies to 2003 and before. For 2007, when the chart is selected, you should be able to do a similar action using the "Select Data" option on the "Design" tab of the ribbon. This opens up a dialog box listing the Series for the chart. You can select the series just as you could in Excel 2003, but you must use the "Add" and "Edit" buttons to define custom series.
I think Link component does not have the props for it.
You can have alternative way by create a tag and use the makeHref method of Navigation mixin to create your url
<a target='_blank' href={this.makeHref(routeConsts.CHECK_DOMAIN, {},
{ realm: userStore.getState().realms[0].name })}>

I got a similar error and it took me a while to realize that in my case I named the array variable payInvoices and the function also payInvoices. It confused AngularJs. Once I changed the name to processPayments() it finally worked. Just wanted to share this error and solution as it took me long time to figure this out.
use this command on your script file after copying it to Linux/Unix
perl -pi -e 's/\r//' scriptfilename
Threading is another possible solution. Although the Celery based solution is better for applications at scale, if you are not expecting too much traffic on the endpoint in question, threading is a viable alternative.
This solution is based on Miguel Grinberg's PyCon 2016 Flask at Scale presentation, specifically slide 41 in his slide deck. His code is also available on github for those interested in the original source.
From a user perspective the code works as follows:
To convert an api call to a background task, simply add the @async_api decorator.
Here is a fully contained example:

You could make your own plugins.
jQuery.fn.visible = function() {
return this.css('visibility', 'visible');
};
jQuery.fn.invisible = function() {
return this.css('visibility', 'hidden');
};
jQuery.fn.visibilityToggle = function() {
return this.css('visibility', function(i, visibility) {
return (visibility == 'visible') ? 'hidden' : 'visible';
});
};
If you want to overload the original jQuery toggle()
, which I don't recommend...
!(function($) {
var toggle = $.fn.toggle;
$.fn.toggle = function() {
var args = $.makeArray(arguments),
lastArg = args.pop();
if (lastArg == 'visibility') {
return this.visibilityToggle();
}
return toggle.apply(this, arguments);
};
})(jQuery);
I just wanted to point out my answer since I know for
loop is faster then $.each
loop
here it is:
just add class="required"
to inputs you want to be required and then in jquery do:
$('#signup_form').submit(function(){
var fields = $('input.required');
for(var i=0;i<fields.length;i++){
if($(fields[i]).val() != ''){
//whatever
}
}
});
Use either a simple blank *
or [:blank:]*
to remove all possible spaces at the end of the line:
sed 's/ *$//' file
Using the [:blank:]
class you are removing spaces and tabs:
sed 's/[[:blank:]]*$//' file
Note this is POSIX, hence compatible in both GNU sed and BSD.
For just GNU sed you can use the GNU extension \s*
to match spaces and tabs, as described in BaBL86's answer. See POSIX specifications on Basic Regular Expressions.
Let's test it with a simple file consisting on just lines, two with just spaces and the last one also with tabs:
$ cat -vet file
hello $
bye $
ha^I $ # there is a tab here
Remove just spaces:
$ sed 's/ *$//' file | cat -vet -
hello$
bye$
ha^I$ # tab is still here!
Remove spaces and tabs:
$ sed 's/[[:blank:]]*$//' file | cat -vet -
hello$
bye$
ha$ # tab was removed!
If you have loads of re-directs to create, having loads of virtual directories over the places is a nightmare to maintain. You could try using ISAPI redirect an IIS extension. Then all you re-directs are managed in one place.
http://www.isapirewrite.com/docs/
It allows also you to match patterns based on reg ex expressions etc. I've used where I've had to re-direct 100's of pages and its saved a lot of time.
Try to play around also with the calc
and overflow
functions
.myClassName {
overflow: auto;
height: calc(100% - 1.5em);
}
The right way is using insertAdjacentHTML
. In Firefox earlier than 8, you can fall back to using Range.createContextualFragment
if your str
contains no script
tags.
If your str
contains script
tags, you need to remove script
elements from the fragment returned by createContextualFragment
before inserting the fragment. Otherwise, the scripts will run. (insertAdjacentHTML
marks scripts unexecutable.)
Vertical alignment doesn't work with floated elements, indeed. That's because float lifts the element from the normal flow of the document. You might want to use other vertical aligning techniques, like the ones based on transform, display: table, absolute positioning, line-height, js (last resort maybe) or even the plain old html table (maybe the first choice if the content is actually tabular). You'll find that there's a heated debate on this issue.
However, this is how you can vertically align YOUR 3 divs:
.wrap{
width: 500px;
overflow:hidden;
background: pink;
}
.left {
width: 150px;
margin-right: 10px;
background: yellow;
display:inline-block;
vertical-align: middle;
}
.left2 {
width: 150px;
margin-right: 10px;
background: aqua;
display:inline-block;
vertical-align: middle;
}
.right{
width: 150px;
background: orange;
display:inline-block;
vertical-align: middle;
}
Not sure why you needed both fixed width, display: inline-block and floating.
Settings->Preferences->Auto-Completion and there check Enable auto-completion on each input. Press Ctrl + Space to get a autocomplete hint. For auto-complete in code type the first letter then press Ctrl + Enter. all the inputs you have given will be listed.
you can do this in different ways:
see here for more details on the second case:
http://msdn.microsoft.com/en-us/library/ff647786.aspx#scalenetchapt10_topic14
and here for details on the last case:
Modify the show search method like this
showSearch(){
this.show = !this.show;
setTimeout(()=>{ // this will make the execution after the above boolean has changed
this.searchElement.nativeElement.focus();
},0);
}
you can try to reinstall the latest version of xcode / dev. tools for snow leopard - this should fix your errors
You can open the other file and type :r file_to_be_copied_from
. Or you can buffer. Or go to the first file, go on the line you want to copy, type "qY
, go to the file you want to paste and type "qP
.
"
buffer_name, copies to the buffer. Y
is yank and P
is put. Hope that helps!

I can confirm that the answer it to upgrade Xcode to 6.1. If you are using Xcode 6.0.x you will not be able to select a device running 8.1. Your deployment targets and OS version should have nothing to do with this.
If your OS version is greater than 10.9.4 I would recommend this. First, un-attaching all devices. Download Xcode 6.1. After opening the new version of Xcode attach your device. You should be good to go.
Another good thing would be to look at the release notes. It's and easy read and gives you a general idea of what still needs to be fixed.
I think I am too late to answer this question but anyways here goes nothing.
I have run in to the same problem before and I think there are two alternative solutions you can choose from.
from time import *
sleep(10)
exit_now = raw_input("Do you like to exit now (Y)es (N)o ? ")'
if exit_now.lower() = 'n'
//more processing here
Alternatively you can use a hybrid of those two methods as well where you can prompt for a message and use sleep(sometime) to delay the window closing as well. choice is yours.
please note the above are just ideas and if you want to use any of those in practice you might have to think about your application logic a bit.
The HTML specification never specifies any content formats. That's not its job. There's plenty of standards organizations that are more qualified than the W3C to specify video formats.
That's what content negotiation is for.
<img>
element.<style>
element.<script>
element.<object>
and embed
elements.<audio>
element.Why should it specify one for the <video>
element?
A simple working solution using vanilla JavaScript:
const valuesToRemove = ["value1", "value2"];
valuesToRemove.forEach(value => {
const mySelect = document.getElementById("my-select");
const valueIndex = Array.from(mySelect.options).findIndex(option => option.value === value);
if (valueIndex > 0) {
mySelect.options.remove(valueIndex);
}
});
Update table set column = (select...)
never worked for me since set only expects 1 value - SQL Error: ORA-01427: single-row subquery returns more than one row.
here's the solution:
BEGIN
For i in (select id, name, desc from table1)
LOOP
Update table2 set name = i.name, desc = i.desc where id = i.id;
END LOOP;
END;
That's how exactly you run it on SQLDeveloper worksheet. They say it's slow but that's the only solution that worked for me on this case.

This is meant to supplement my Objective-C answer for Swift users, to keep the Objective-C answer from getting too big.
First, set up the in-app purchase on appstoreconnect.apple.com. Follow the beginning part of my Objective-C answer (steps 1-13, under the App Store Connect header) for instructions on doing that.
It could take a few hours for your product ID to register in App Store Connect, so be patient.
Now that you've set up your in-app purchase information on App Store Connect, we need to add Apple's framework for in-app-purchases, StoreKit
, to the app.
Go into your Xcode project, and go to the application manager (blue page-like icon at the top of the left bar where your app's files are). Click on your app under targets on the left (it should be the first option), then go to "Capabilities" at the top. On the list, you should see an option "In-App Purchase". Turn this capability ON, and Xcode will add StoreKit
to your project.
Now, we're going to start coding!
First, make a new swift file that will manage all of your in-app-purchases. I'm going to call it IAPManager.swift
.
In this file, we're going to create a new class, called IAPManager
that is a SKProductsRequestDelegate
and SKPaymentTransactionObserver
. At the top, make sure you import Foundation
and StoreKit
import Foundation
import StoreKit
public class IAPManager: NSObject, SKProductsRequestDelegate,
SKPaymentTransactionObserver {
}
Next, we're going to add a variable to define the identifier for our in-app purchase (you could also use an enum
, which would be easier to maintain if you have multiple IAPs).
// This should the ID of the in-app-purchase you made on AppStore Connect.
// if you have multiple IAPs, you'll need to store their identifiers in
// other variables, too (or, preferably in an enum).
let removeAdsID = "com.skiplit.removeAds"
Let's add an initializer for our class next:
// This is the initializer for your IAPManager class
//
// A better, and more scaleable way of doing this
// is to also accept a callback in the initializer, and call
// that callback in places like the paymentQueue function, and
// in all functions in this class, in place of calls to functions
// in RemoveAdsManager (you'll see those calls in the code below).
let productID: String
init(productID: String){
self.productID = productID
}
Now, we're going to add the required functions for SKProductsRequestDelegate
and SKPaymentTransactionObserver
to work:
We'll add the RemoveAdsManager
class later
// This is called when a SKProductsRequest receives a response
public func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse){
// Let's try to get the first product from the response
// to the request
if let product = response.products.first{
// We were able to get the product! Make a new payment
// using this product
let payment = SKPayment(product: product)
// add the new payment to the queue
SKPaymentQueue.default().add(self)
SKPaymentQueue.default().add(payment)
}
else{
// Something went wrong! It is likely that either
// the user doesn't have internet connection, or
// your product ID is wrong!
//
// Tell the user in requestFailed() by sending an alert,
// or something of the sort
RemoveAdsManager.removeAdsFailure()
}
}
// This is called when the user restores their IAP sucessfully
private func paymentQueueRestoreCompletedTransactionsFinished(_ queue: SKPaymentQueue){
// For every transaction in the transaction queue...
for transaction in queue.transactions{
// If that transaction was restored
if transaction.transactionState == .restored{
// get the producted ID from the transaction
let productID = transaction.payment.productIdentifier
// In this case, we have only one IAP, so we don't need to check
// what IAP it is. However, this is useful if you have multiple IAPs!
// You'll need to figure out which one was restored
if(productID.lowercased() == IAPManager.removeAdsID.lowercased()){
// Restore the user's purchases
RemoveAdsManager.restoreRemoveAdsSuccess()
}
// finish the payment
SKPaymentQueue.default().finishTransaction(transaction)
}
}
}
// This is called when the state of the IAP changes -- from purchasing to purchased, for example.
// This is where the magic happens :)
public func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]){
for transaction in transactions{
// get the producted ID from the transaction
let productID = transaction.payment.productIdentifier
// In this case, we have only one IAP, so we don't need to check
// what IAP it is.
// However, if you have multiple IAPs, you'll need to use productID
// to check what functions you should run here!
switch transaction.transactionState{
case .purchasing:
// if the user is currently purchasing the IAP,
// we don't need to do anything.
//
// You could use this to show the user
// an activity indicator, or something like that
break
case .purchased:
// the user successfully purchased the IAP!
RemoveAdsManager.removeAdsSuccess()
SKPaymentQueue.default().finishTransaction(transaction)
case .restored:
// the user restored their IAP!
IAPTestingHandler.restoreRemoveAdsSuccess()
SKPaymentQueue.default().finishTransaction(transaction)
case .failed:
// The transaction failed!
RemoveAdsManager.removeAdsFailure()
// finish the transaction
SKPaymentQueue.default().finishTransaction(transaction)
case .deferred:
// This happens when the IAP needs an external action
// in order to proceeded, like Ask to Buy
RemoveAdsManager.removeAdsDeferred()
break
}
}
}
Now let's add some functions that can be used to start a purchase or a restore purchases:
// Call this when you want to begin a purchase
// for the productID you gave to the initializer
public func beginPurchase(){
// If the user can make payments
if SKPaymentQueue.canMakePayments(){
// Create a new request
let request = SKProductsRequest(productIdentifiers: [productID])
// Set the request delegate to self, so we receive a response
request.delegate = self
// start the request
request.start()
}
else{
// Otherwise, tell the user that
// they are not authorized to make payments,
// due to parental controls, etc
}
}
// Call this when you want to restore all purchases
// regardless of the productID you gave to the initializer
public func beginRestorePurchases(){
// restore purchases, and give responses to self
SKPaymentQueue.default().add(self)
SKPaymentQueue.default().restoreCompletedTransactions()
}
Next, let's add a new utilities class to manage our IAPs. All of this code could be in one class, but having it multiple makes it a little cleaner. I'm going to make a new class called RemoveAdsManager
, and in it, put a few functions
public class RemoveAdsManager{
class func removeAds()
class func restoreRemoveAds()
class func areAdsRemoved() -> Bool
class func removeAdsSuccess()
class func restoreRemoveAdsSuccess()
class func removeAdsDeferred()
class func removeAdsFailure()
}
The first three functions, removeAds
, restoreRemoveAds
, and areAdsRemoved
, are functions that you'll call to do certain actions. The last four are one that will be called by IAPManager
.
Let's add some code to the first two functions, removeAds
and restoreRemoveAds
:
// Call this when the user wants
// to remove ads, like when they
// press a "remove ads" button
class func removeAds(){
// Before starting the purchase, you could tell the
// user that their purchase is happening, maybe with
// an activity indicator
let iap = IAPManager(productID: IAPManager.removeAdsID)
iap.beginPurchase()
}
// Call this when the user wants
// to restore their IAP purchases,
// like when they press a "restore
// purchases" button.
class func restoreRemoveAds(){
// Before starting the purchase, you could tell the
// user that the restore action is happening, maybe with
// an activity indicator
let iap = IAPManager(productID: IAPManager.removeAdsID)
iap.beginRestorePurchases()
}
And lastly, let's add some code to the last five functions.

}
Lastly, you need to add some way for the user to start the purchase and call RemoveAdsManager.removeAds()
and start a restore and call RemoveAdsManager.restoreRemoveAds()
, like a button somewhere! Keep in mind that, per the App Store guidelines, you do need to provide a button to restore purchases somewhere.
The last thing to do is submit your IAP for review on App Store Connect! For detailed instructions on doing that, you can follow the last part of my Objective-C answer, under the Submitting for review header.
By the way. whenever my forms call the formclosed or form closing event I close the applciation with a this.Hide() function. Does that affect how my application is behaving now?
In short, yes. The entire application will end when the main form (the form started via Application.Run
in the Main
method) is closed (not hidden).
If your entire application should always fully terminate whenever your main form is closed then you should just remove that form closed handler. By not canceling that event and just letting them form close when the user closes it you will get your desired behavior. As for all of the other forms, if you don't intend to show that same instance of the form again you just just let them close, rather than preventing closure and hiding them. If you are showing them again, then hiding them may be fine.
If you want to be able to have the user click the "x" for your main form, but have another form stay open and, in effect, become the "new" main form, then it's a bit more complicated. In such a case you will need to just hide your main form rather than closing it, but you'll need to add in some sort of mechanism that will actually close the main form when you really do want your app to end. If this is the situation that you're in then you'll need to add more details to your question describing what types of applications should and should not actually end the program.
You can modify various VM properties by adding the following configuration (see the Vagrant docs for a bit more info):
# Configure VM Ram usage
config.vm.customize [
"modifyvm", :id,
"--name", "Test_Environment",
"--memory", "1024"
]
You can obtain the properties that you want to change from the documents for VirtualBox command-line options:
The vagrant documentation has the section on how to change IP address:
Vagrant::Config.run do |config|
config.vm.network :hostonly, "192.168.50.4"
end
Also you can restructure the configuration like this, ending is do with end without nesting it. This is simpler.
config.vm.define :web do |web_config|
web_config.vm.box = "lucid32"
web_config.vm.forward_port 80, 8080
end
web_config.vm.provision :puppet do |puppet|
puppet.manifests_path = "manifests"
puppet.manifest_file = "lucid32.pp"
end
Webpack configuration is being handled by react-scripts. You can find all webpack config inside node_modules react-scripts/config.
And If you want to customize webpack config, you can follow this customize-webpack-config
This should work:
var matches = text.match(/\[(\d+)\][(\d+)\]/);
var productId = matches[1];
var shopId = matches[2];
When you call Business.where(:user_id => current_user.id)
you will get an array. This Array may have no objects or one or many objects in it, but it won't be null. Thus the check == nil will never be true.
You can try the following:
if Business.where(:user_id => current_user.id).count == 0
So you check the number of elements in the array and compare them to zero.
or you can try:
if Business.find_by_user_id(current_user.id).nil?
this will return one or nil.
It sounds like the application isn't signed. Download ldid from Cydia and then use it like so: ldid -S /Applications/AccelerometerGraph.app/AccelerometerGraph
Also be sure that the binary is marked as executable: chmod +x /Applications/AccelerometerGraph.app/AccelerometerGraph
1) When to use include directive ?
To prevent duplication of same output logic across multiple jsp's of the web app ,include mechanism is used ie.,to promote the re-usability of presentation logic include directive is used
<%@ include file="abc.jsp" %>
when the above instruction is received by the jsp engine,it retrieves the source code of the abc.jsp and copy's the same inline in the current jsp. After copying translation is performed for the current page
Simply saying it is static instruction to jsp engine ie., whole source code of "abc.jsp" is copied into the current page
2) When to use include action ?
include tag doesn't include the source code of the included page into the current page instead the output generated at run time by the included page is included into the current page response
include tag functionality is similar to that of include mechanism of request dispatcher of servlet programming
include tag is run-time instruction to jsp engine ie., rather copying whole code into current page a method call is made to "abc.jsp" from current page
This is what you need to add to make it work.
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Credentials", "true");
response.setHeader("Access-Control-Allow-Methods", "GET,HEAD,OPTIONS,POST,PUT");
response.setHeader("Access-Control-Allow-Headers", "Access-Control-Allow-Headers, Origin,Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers");
The browser sends a preflight request (with method type OPTIONS) to check if the service hosted on the server is allowed to be accessed from the browser on a different domain. In response to the preflight request if you inject above headers the browser understands that it is ok to make further calls and i will get a valid response to my actual GET/POST call. you can constraint the domain to which access is granted by using Access-Control-Allow-Origin", "localhost, xvz.com" instead of * . ( * will grant access to all domains)
This has been asked before. .Net has a built-in ConvertAll function for converting between an array of one type to an array of another type. You can combine this with Split to separate the string to an array of strings
Example function:
static int[] ToIntArray(this string value, char separator)
{
return Array.ConvertAll(value.Split(separator), s=>int.Parse(s));
}
I was face same problem ..... And I got solution by using typeof()
if (typeof(value) !== 'undefined' && value != null) {
console.log('Not Undefined and Not Null')
} else {
console.log('Undefined or Null')
}
You must have to use typeof()
to identified undefined
If you have the correct headers defined & are using a non GlibC
library (such as Musl C) gcc
will also throw error: implicit declaration of function
when GNU extensions such as malloc_trim
are encountered.
The solution is to wrap the extension & the header:
#if defined (__GLIBC__)
malloc_trim(0);
#endif
You can also use the didSet
to set the variable to a different value. This does not cause the observer to be called again as stated in Properties guide. For example, it is useful when you want to limit the value as below:
let minValue = 1
var value = 1 {
didSet {
if value < minValue {
value = minValue
}
}
}
value = -10 // value is minValue now.
The best that I've been able to do is
$(this).closest('.modal').modal('toggle');
This gets the modal holding the DOM object you triggered the event on (guessing you're clicking a button). Gets the closest parent '.modal' and toggles it. Obviously only works because it's inside the modal you clicked.
You can however do this:
$(".modal:visible").modal('toggle');
This gets the modal that is displaying (since you can only have one open at a time), and triggers the 'toggle' This would not work without ":visible"
You can see the Simulator console window, including Safari Web Inspector and all the Web Development Tools by using the Safari Technology Preview app. Open your page in Safari on the Simulator and then go to Safari Technology Preview > Develop > Simulator.
You can use
try {
user.OtherFriend = row["US_OTHERFRIEND"].ToString();
}
catch (Exception ex)
{
// do something if you want
}
Just to add to the others, you can pass a function name:
function someFunc($a)
{
echo $a;
}
function callFunc($name)
{
$name('funky!');
}
callFunc('someFunc');
This will work in PHP4.
use this Reload page
success: function(data){
if(data.success == true){ // if true (1)
setTimeout(function(){// wait for 5 secs(2)
location.reload(); // then reload the page.(3)
}, 5000);
}
}
This happens because Oracle dropped support for Windows XP (which doesn't have RegDeleteKeyExA
used by the installer in its ADVAPI32.DLL
by the way) as described in http://mail.openjdk.java.net/pipermail/openjfx-dev/2013-July/009005.html. Yet while the official support for XP has ended, the Java binaries are still (as of Java 8u20 EA b05 at least) XP-compatible - only the installer isn't...
Because of that, the solution is actually quite easy:
get 7-Zip (or any other good unpacker), unpack the distribution .exe manually, it has one .zip file inside of it (tools.zip
), extract it too,
use unpack200
from JDK8 to unpack all .pack files to .jar files (older unpacks won't work properly); JAVA_HOME
environment variable should be set to your Java unpack root, e.g. "C:\Program Files\Java\jdk8" - you can specify it implicitly by e.g.
SET JAVA_HOME=C:\Program Files\Java\jdk8
Unpack all files with a single command (in batch file):
FOR /R %%f IN (*.pack) DO "%JAVA_HOME%\bin\unpack200.exe" -r -v "%%f" "%%~pf%%~nf.jar"
Unpack all files with a single command (command line from JRE root):
FOR /R %f IN (*.pack) DO "bin\unpack200.exe" -r -v "%f" "%~pf%~nf.jar"
Unpack by manually locating the files and unpacking them one-by-one:
%JAVA_HOME%\bin\unpack200 -r packname.pack packname.jar
where packname
is for example rt
point the tool you want to use (e.g. Netbeans) to the %JAVA_HOME%
and you're good to go.
Note: you probably shouldn't do this just to use Java 8 in your web browser or for any similar reason (installing JRE 8 comes to mind); security flaws in early updates of major Java version releases are (mind me) legendary, and adding to that no real support for neither XP nor Java 8 on XP only makes matters much worse. Not to mention you usually don't need Java in your browser (see e.g. http://nakedsecurity.sophos.com/2013/01/15/disable-java-browsers-homeland-security/ - the topic is already covered on many pages, just Google it if you require further info). In any case, AFAIK the only thing required to apply this procedure to JRE is to change some of the paths specified above from \bin\
to \lib\
(the file placement in installer directory tree is a bit different) - yet I strongly advise against doing it.
See also: How can I get the latest JRE / JDK as a zip file rather than EXE or MSI installer?, JRE 1.7 - java version - returns: java/lang/NoClassDefFoundError: java/lang/Object
You can create a StreamReader
around the stream, then call StreamReader.ReadToEnd()
.
StreamReader responseReader = new StreamReader(request.GetResponse().GetResponseStream());
var responseData = responseReader.ReadToEnd();
You can write extention method:
public static async Task<Tout> ReadAsAsync<Tout>(this System.Net.Http.HttpContent content) {
return Newtonsoft.Json.JsonConvert.DeserializeObject<Tout>(await content.ReadAsStringAsync());
}
For me - here is a less confusing way of doing the socket.setTimeout
var request=require('https').get(
url
,function(response){
var r='';
response.on('data',function(chunk){
r+=chunk;
});
response.on('end',function(){
console.dir(r); //end up here if everything is good!
});
}).on('error',function(e){
console.dir(e.message); //end up here if the result returns an error
});
request.on('error',function(e){
console.dir(e); //end up here if a timeout
});
request.on('socket',function(socket){
socket.setTimeout(1000,function(){
request.abort(); //causes error event ?
});
});
On Windows maybe the play "run 9001" will not work. You have to change the play.bat file. See Ticket
There are no problems with the second version of the assignment operator. In fact, that is the standard way for an assignment operator.
Edit: Note that I am referring to the return type of the assignment operator, not to the implementation itself. As has been pointed out in comments, the implementation itself is another issue. See here.
From a user experience stand-point, you don't want a major action to be done passively.
Something major like a window close should be the result of an action by the user.
In my own experience where I needed to try and find out what some old VB6 programs were doing, I turned to Process Explorer (Sysinternals). I did the following:
This didn't show the actual functions, but it listed their names, folders of where files were being copied from and to and if it accessed a DB it would also display the connection string. Enough to help you get an idea, but may be useless for complex programs. The programs I was looking at were pretty basic (no pun intended).
YMMV.
You can write as follows:
SqlCommand check_User_Name = new SqlCommand("SELECT * FROM Table WHERE ([user] = '" + txtBox_UserName.Text + "') ", conn);
if (check_User_Name.ExecuteScalar()!=null)
{
int UserExist = (int)check_User_Name.ExecuteScalar();
if (UserExist > 0)
{
//Username Exist
}
}
There's a couple ways of doing this. As long as the WAR file is expanded (a set of files instead of one .war file), you can use this API:
ServletContext context = getContext();
String fullPath = context.getRealPath("/WEB-INF/test/foo.txt");
That will get you the full system path to the resource you are looking for. However, that won't work if the Servlet Container never expands the WAR file (like Tomcat). What will work is using the ServletContext's getResource
methods.
ServletContext context = getContext();
URL resourceUrl = context.getResource("/WEB-INF/test/foo.txt");
or alternatively if you just want the input stream:
InputStream resourceContent = context.getResourceAsStream("/WEB-INF/test/foo.txt");
The latter approach will work no matter what Servlet Container you use and where the application is installed. The former approach will only work if the WAR file is unzipped before deployment.
EDIT:
The getContext() method is obviously something you would have to implement. JSP pages make it available as the context
field. In a servlet you get it from your ServletConfig
which is passed into the servlet's init()
method. If you store it at that time, you can get your ServletContext any time you want after that.
Here is an elegant method using quaternions that are blazingly fast; I can calculate 10 million rotations per second with appropriately vectorised numpy arrays. It relies on the quaternion extension to numpy found here.
Quaternion Theory:
A quaternion is a number with one real and 3 imaginary dimensions usually written as q = w + xi + yj + zk
where 'i', 'j', 'k' are imaginary dimensions. Just as a unit complex number 'c' can represent all 2d rotations by c=exp(i * theta)
, a unit quaternion 'q' can represent all 3d rotations by q=exp(p)
, where 'p' is a pure imaginary quaternion set by your axis and angle.
We start by converting your axis and angle to a quaternion whose imaginary dimensions are given by your axis of rotation, and whose magnitude is given by half the angle of rotation in radians. The 4 element vectors (w, x, y, z)
are constructed as follows:
import numpy as np
import quaternion as quat
v = [3,5,0]
axis = [4,4,1]
theta = 1.2 #radian
vector = np.array([0.] + v)
rot_axis = np.array([0.] + axis)
axis_angle = (theta*0.5) * rot_axis/np.linalg.norm(rot_axis)
First, a numpy array of 4 elements is constructed with the real component w=0 for both the vector to be rotated vector
and the rotation axis rot_axis
. The axis angle representation is then constructed by normalizing then multiplying by half the desired angle theta
. See here for why half the angle is required.
Now create the quaternions v
and qlog
using the library, and get the unit rotation quaternion q
by taking the exponential.
vec = quat.quaternion(*v)
qlog = quat.quaternion(*axis_angle)
q = np.exp(qlog)
Finally, the rotation of the vector is calculated by the following operation.
v_prime = q * vec * np.conjugate(q)
print(v_prime) # quaternion(0.0, 2.7491163, 4.7718093, 1.9162971)
Now just discard the real element and you have your rotated vector!
v_prime_vec = v_prime.imag # [2.74911638 4.77180932 1.91629719] as a numpy array
Note that this method is particularly efficient if you have to rotate a vector through many sequential rotations, as the quaternion product can just be calculated as q = q1 * q2 * q3 * q4 * ... * qn and then the vector is only rotated by 'q' at the very end using v' = q * v * conj(q).
This method gives you a seamless transformation between axis angle <---> 3d rotation operator simply by exp
and log
functions (yes log(q)
just returns the axis-angle representation!). For further clarification of how quaternion multiplication etc. work, see here
Unfortunately, the most common use of <a href="#">
is by lazy programmers who want clickable non-hyperlink javascript-coded elements that behave like anchors, but they can't be arsed to add cursor: pointer;
or :hover
styles to a class for their non-hyperlink elements, and are additionally too lazy to set href
to javascript:void(0);
.
The problem with this is that one <a href="#" onclick="some_function();">
or another inevitably ends up with a javascript error, and an anchor with an onclick javascript error always ends up following its href
. Normally this ends up being an annoying jump to the top of the page, but in the case of sites using <base>
, <a href="#">
is handled as <a href="[base href]/#">
, resulting in an unexpected navigation. If any logable errors are being generated, you won't see them in the latter case unless you enable persistent logs.
If an anchor element is used as a non-anchor it should have its href
set to javascript:void(0);
for the sake of graceful degradation.
I just wasted two days debugging a random unexpected page redirect that should have simply refreshed the page, and finally tracked it down to a function raising the click event of an <a href="#">
. Replacing the #
with javascript:void(0);
fixed it.
The first thing I'm doing Monday is purging the project of all instances of <a href="#">
.
As others have answered, the mysqli API can execute multi-queries with the msyqli_multi_query() function.
For what it's worth, PDO supports multi-query by default, and you can iterate over the multiple result sets of your multiple queries:
$stmt = $dbh->prepare("
select sql_calc_found_rows * from foo limit 1 ;
select found_rows()");
$stmt->execute();
do {
while ($row = $stmt->fetch()) {
print_r($row);
}
} while ($stmt->nextRowset());
However, multi-query is pretty widely considered a bad idea for security reasons. If you aren't careful about how you construct your query strings, you can actually get the exact type of SQL injection vulnerability shown in the classic "Little Bobby Tables" XKCD cartoon. When using an API that restrict you to single-query, that can't happen.

Recursion occurs when something contains, or uses, a similar version of itself.When talking specifically about computer programming, recursion occurs when a function calls itself.
The following link helps me to understand recursion better, even I consider this is the best so far what I've learned.
It comes with an example to understand how the inner(recursive) functions called while executing.
Please go through the article and I have pasted the test program in case if the article got trashed. You may please run the program in local server to see it in action.

The concept of a HOME directory seems to be a bit vague when it comes to Windows. If the environment variables (HOMEDRIVE/HOMEPATH/USERPROFILE) aren't enough, you may have to resort to using native functions via JNI or JNA. SHGetFolderPath allows you to retrieve special folders, like My Documents (CSIDL_PERSONAL) or Local Settings\Application Data (CSIDL_LOCAL_APPDATA).
Sample JNA code:
public class PrintAppDataDir {
public static void main(String[] args) {
if (com.sun.jna.Platform.isWindows()) {
HWND hwndOwner = null;
int nFolder = Shell32.CSIDL_LOCAL_APPDATA;
HANDLE hToken = null;
int dwFlags = Shell32.SHGFP_TYPE_CURRENT;
char[] pszPath = new char[Shell32.MAX_PATH];
int hResult = Shell32.INSTANCE.SHGetFolderPath(hwndOwner, nFolder,
hToken, dwFlags, pszPath);
if (Shell32.S_OK == hResult) {
String path = new String(pszPath);
int len = path.indexOf('\0');
path = path.substring(0, len);
System.out.println(path);
} else {
System.err.println("Error: " + hResult);
}
}
}
private static Map<String, Object> OPTIONS = new HashMap<String, Object>();
static {
OPTIONS.put(Library.OPTION_TYPE_MAPPER, W32APITypeMapper.UNICODE);
OPTIONS.put(Library.OPTION_FUNCTION_MAPPER,
W32APIFunctionMapper.UNICODE);
}
static class HANDLE extends PointerType implements NativeMapped {
}
static class HWND extends HANDLE {
}
static interface Shell32 extends Library {
public static final int MAX_PATH = 260;
public static final int CSIDL_LOCAL_APPDATA = 0x001c;
public static final int SHGFP_TYPE_CURRENT = 0;
public static final int SHGFP_TYPE_DEFAULT = 1;
public static final int S_OK = 0;
static Shell32 INSTANCE = (Shell32) Native.loadLibrary("shell32",
Shell32.class, OPTIONS);

On Linux, I had the same problem of getting rid of the buffering. I finally used "stdbuf -o0" (or, unbuffer from expect) to get rid of the PIPE buffering.
proc = Popen(['stdbuf', '-o0'] + cmd, stdout=PIPE, stderr=PIPE)
stdout = proc.stdout
I could then use select.select on stdout.
It's worth noting, since it's confusing for people new to XML, that the root (or document node) of an XML document is not the top-level element. It's the parent of the top-level element. This is confusing because it doesn't seem like the top-level element can have a parent. Isn't it the top level?
But look at this, a well-formed XML document:
<?xml-stylesheet href="my_transform.xsl" type="text/xsl"?>
<!-- Comments and processing instructions are XML nodes too, remember. -->
<TopLevelElement/>
The root of this document has three children: a processing instruction, a comment, and an element.
So, for example, if you wanted to write a transform that got rid of that comment, but left in any comments appearing anywhere else in the document, you'd add this to the identity transform:
<xsl:template match="/comment()"/>
Even simpler (and more commonly useful), here's an XPath pattern that matches the document's top-level element irrespective of its name: /*
.
Here is a solution that defines a git alias, so you will be able use it like that :
git rblame -M -n -L '/REGEX/,+1' FILE
Output example :
00000000 18 (Not Committed Yet 2013-08-19 13:04:52 +0000 728) fooREGEXbar
15227b97 18 (User1 2013-07-11 18:51:26 +0000 728) fooREGEX
1748695d 23 (User2 2013-03-19 21:09:09 +0000 741) REGEXbar
You can define the alias in your .gitconfig or simply run the following command
git config alias.rblame !sh -c 'while line=$(git blame "$@" $commit 2>/dev/null); do commit=${line:0:8}^; [ 00000000^ == $commit ] && commit=$(git rev-parse HEAD); echo $line; done' dumb_param
This is an ugly one-liner, so here is a de-obfuscated equivalent bash function :
git-rblame () {
local commit line
while line=$(git blame "$@" $commit 2>/dev/null); do
commit="${line:0:8}^"
if [ "00000000^" == "$commit" ]; then
commit=$(git rev-parse HEAD)
fi
echo $line
done
}
The pickaxe solution ( git log --pickaxe-regex -S'REGEX' ) will only give you line additions/deletions, not the other alterations of the line containing the regular expression.
A limitation of this solution is that git blame only returns the 1st REGEX match, so if multiple matches exist the recursion may "jump" to follow another line. Be sure to check the full history output to spot those "jumps" and then fix your REGEX to ignore the parasite lines.
Finally, here is an alternate version that run git show on each commit to get the full diff :
git config alias.rblameshow !sh -c 'while line=$(git blame "$@" $commit 2>/dev/null); do commit=${line:0:8}^; [ 00000000^ == $commit ] && commit=$(git rev-parse HEAD); git show $commit; done' dumb_param
If you prefer using method (lambda) syntax as I do, you could do the same thing like this:
var result = new TableName();
using(var db = new EFObjectContext)
{
var query = db.TableName;
query = value1 == null
? query.Where(tbl => tbl.entry1 == null)
: query.Where(tbl => tbl.entry1 == value1);
query = value2 == null
? query.Where(tbl => tbl.entry2 == null)
: query.Where(tbl => tbl.entry2 == value2);
result = query
.Select(tbl => tbl)
.FirstOrDefault();
// Inspect the value of the trace variable below to see the sql generated by EF
var trace = ((ObjectQuery<REF_EQUIPMENT>) query).ToTraceString();
}
return result;
Utilizing the "dynamic table" capability in SQL Server (querying against a parenthesis-surrounded query), you can return 2000, 49 w/ the following. If your platform doesn't offer an equivalent to the "dynamic table" ANSI-extention, you can always utilize a temp table in two-steps/statement by inserting the results within the "dynamic table" to a temp table, and then performing a subsequent select on the temp table.
DECLARE @T TABLE(
[contract] INT,
project INT,
activity INT
)
INSERT INTO @T VALUES( 1000, 8000, 10 )
INSERT INTO @T VALUES( 1000, 8000, 20 )

INSERT INTO @T VALUES( 3000, 9000, 79 )

My guess is that the webpage is listening to mousedown rather than click (which is bad for accessibility because when a user uses the keyboard, only focus and click are fired, not mousedown). So you should simulate mousedown, click, and mouseup (which, by the way, is what the iPhone, iPod Touch, and iPad do on tap events).
To simulate the mouse events, you can use this snippet for browsers that support DOM 2 Events. For a more foolproof simulation, fill in the mouse position using initMouseEvent
instead.
// DOM 2 Events
var dispatchMouseEvent = function(target, var_args) {
var e = document.createEvent("MouseEvents");
// If you need clientX, clientY, etc., you can call
// initMouseEvent instead of initEvent
e.initEvent.apply(e, Array.prototype.slice.call(arguments, 1));
target.dispatchEvent(e);
};
dispatchMouseEvent(element, 'mouseover', true, true);
dispatchMouseEvent(element, 'mousedown', true, true);
dispatchMouseEvent(element, 'click', true, true);
dispatchMouseEvent(element, 'mouseup', true, true);
When you fire a simulated click event, the browser will actually fire the default action (e.g. navigate to the link's href, or submit a form).
In IE, the equivalent snippet is this (unverified since I don't have IE). I don't think you can give the event handler mouse positions.
// IE 5.5+
element.fireEvent("onmouseover");
element.fireEvent("onmousedown");
element.fireEvent("onclick"); // or element.click()
element.fireEvent("onmouseup");
You can simulate keydown and keypress events, but unfortunately in Chrome they only fire the event handlers and don't perform any of the default actions. I think this is because the DOM 3 Events working draft describes this funky order of key events:
This means that you have to (while combing the HTML5 and DOM 3 Events drafts) simulate a large amount of what the browser would otherwise do. I hate it when I have to do that. For example, this is roughly how to simulate a key press on an input or textarea.
// DOM 3 Events
var dispatchKeyboardEvent = function(target, initKeyboradEvent_args) {
var e = document.createEvent("KeyboardEvents");
e.initKeyboardEvent.apply(e, Array.prototype.slice.call(arguments, 1));
target.dispatchEvent(e);
};
var dispatchTextEvent = function(target, initTextEvent_args) {
var e = document.createEvent("TextEvent");
e.initTextEvent.apply(e, Array.prototype.slice.call(arguments, 1));
target.dispatchEvent(e);
};
var dispatchSimpleEvent = function(target, type, canBubble, cancelable) {
var e = document.createEvent("Event");
e.initEvent.apply(e, Array.prototype.slice.call(arguments, 1));
target.dispatchEvent(e);
};
var canceled = !dispatchKeyboardEvent(element,
'keydown', true, true, // type, bubbles, cancelable
null, // window
'h', // key
0, // location: 0=standard, 1=left, 2=right, 3=numpad, 4=mobile, 5=joystick
''); // space-sparated Shift, Control, Alt, etc.
dispatchKeyboardEvent(
element, 'keypress', true, true, null, 'h', 0, '');
if (!canceled) {
if (dispatchTextEvent(element, 'textInput', true, true, null, 'h', 0)) {
element.value += 'h';
dispatchSimpleEvent(element, 'input', false, false);
// not supported in Chrome yet
// if (element.form) element.form.dispatchFormInput();
dispatchSimpleEvent(element, 'change', false, false);
// not supported in Chrome yet
// if (element.form) element.form.dispatchFormChange();
}
}
dispatchKeyboardEvent(
element, 'keyup', true, true, null, 'h', 0, '');
I don't think it is possible to simulate key events in IE.

You can write SQL query in any of your favorite database e.g. MySQL, Microsoft SQL Server or Oracle. You can also use database specific feature e.g. TOP, LIMIT or ROW_NUMBER to write SQL query, but you must also provide a generic solution which should work on all database. In fact, there are several ways to find second highest salary and you must know a couple of them e.g. in MySQL without using the LIMIT keyword, in SQL Server without using TOP and in Oracle without using RANK and ROWNUM.
Generic SQL query:
SELECT
MAX(salary)
FROM
Employee
WHERE
Salary NOT IN (
SELECT
Max(Salary)
FROM
Employee
);
Another solution which uses sub query instead of NOT IN clause. It uses <
operator.
SELECT
MAX(Salary)
FROM
Employee
WHERE
Salary < (
SELECT
Max(Salary)
FROM
Employee
);
Given a list:
var list = new List<Child>()
{
new Child()
{School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "John"},
new Child()
{School = "School2", FavoriteColor = "blue", Friend = "Bob", Name = "Pete"},
new Child()
{School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "Fred"},
new Child()
{School = "School2", FavoriteColor = "blue", Friend = "Fred", Name = "Bob"},
};
The query would look like:
var newList = list
.GroupBy(x => new {x.School, x.Friend, x.FavoriteColor})
.Select(y => new ConsolidatedChild()
{
FavoriteColor = y.Key.FavoriteColor,
Friend = y.Key.Friend,
School = y.Key.School,
Children = y.ToList()
}
);
Test code:
foreach(var item in newList)
{
Console.WriteLine("School: {0} FavouriteColor: {1} Friend: {2}", item.School,item.FavoriteColor,item.Friend);
foreach(var child in item.Children)
{
Console.WriteLine("\t Name: {0}", child.Name);
}
}
Result:
School: School1 FavouriteColor: blue Friend: Bob
Name: John
Name: Fred
School: School2 FavouriteColor: blue Friend: Bob
Name: Pete
School: School2 FavouriteColor: blue Friend: Fred
Name: Bob

If you are starting new and its a java application then Spring ROO looks very interesting too!
Hope that helps.
just to add some clarity, you need to stage changes with git add
, then amend last commit:
git add /path/to/modified/files
git commit --amend --no-edit
This is especially useful for if you forgot to add some changes in last commit or when you want to add more changes without creating new commits by reusing the last commit.
parseint
will truncate any decimal values (e.g. 1.5em
gives 1
).
Try a replace
function with regex
e.g.
$this.css('marginBottom').replace(/([\d.]+)(px|pt|em|%)/,'$1');

I experienced this error when running some very memory-expensive processes. When the system started to run short of memory, I begun to notice this kind of error. I had to change the algorithm in order to make a better use of RAM.
To be noted that while some threads threw this exception, some other threw:
System.Data.SqlClient.SqlException (0x80131904): Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement. This could be because the pre-login handshake failed or the server was unable to respond back in time. The duration spent while attempting to connect to this server was - [Pre-Login] initialization=43606; handshake=560; ---> System.ComponentModel.Win32Exception (0x80004005): The wait operation timed out
Both problems disappeared after the system was changed so that it could run using less RAM.

I believe you may need the Typescript typings for JQuery. Since you said you're using Visual Studio, you could use Nuget to get them.
https://www.nuget.org/packages/jquery.TypeScript.DefinitelyTyped/
The command in Nuget Package Manager Console is
Install-Package jquery.TypeScript.DefinitelyTyped
Update: As noted in the comment this package hasn't been updated since 2016. But you can still visit their Github page at https://github.com/DefinitelyTyped/DefinitelyTyped and download the types. Navigate the folder for your library and then download the index.d.ts
file there. Pop it anywhere in your project directory and VS should use it right away.
ReentrantReadWriteLock
is a specialized lock whereas synchronized(this)
is a general purpose lock. They are similar but not quite the same.
You are right in that you could use synchronized(this)
instead of ReentrantReadWriteLock
but the opposite is not always true.
If you'd like to better understand what makes ReentrantReadWriteLock
special look up some information about producer-consumer thread synchronization.
In general you can remember that whole-method synchronization and general purpose synchronization (using the synchronized
keyword) can be used in most applications without thinking too much about the semantics of the synchronization but if you need to squeeze performance out of your code you may need to explore other more fine-grained, or special-purpose synchronization mechanisms.
By the way, using synchronized(this)
- and in general locking using a public class instance - can be problematic because it opens up your code to potential dead-locks because somebody else not knowingly might try to lock against your object somewhere else in the program.
I guess root of this question is that people believe that a call to a constructor creates the object. That is not the case. Java nowhere claims that a constructor call creates an object. It just does what we want constructor to do, like initialising some fields..that's all. So an abstract class's constructor being called doesn't mean that its object is created.
With Chart.js V2.0 you can to do the following:
websiteChart.config.data = some_new_data;
websiteChart.update();
I think that you should use a connection pool instead of share a single connection. A connection pool would provide a much better performance, as you can check here.
As stated in the library documentation, it occurs because the MySQL protocol is sequential (this means that you need multiple connections to execute queries in parallel).
On Windows in general, running command prompt with administrator works. But if you don't want to do that every time, specify Full control permissions of your user (or simply all users) on Anaconda3 directory. Be aware that specifying it for all users allows other users to install their own packages and modify the content.
Ran into a issue with the HTTPClient, even with the suggestions still could not get it to authenticate. Turns out I needed a trailing '/' in my relative path.
i.e.

<!--[if lt IE 8]><![endif]-->
The lt in the above statement means less than, so 'if less than IE 8'.
For all versions of IE you can just use
<!--[if IE]><![endif]-->
or for all versions above ie 6 for example.
<!--[if gt IE 6]><![endif]-->
Where gt is 'greater than'
If you would like to write specific styles for versions below and including IE8 you can write

From stack trace:
HikariPool: Timeout failure pool HikariPool-0 stats (total=20, active=20, idle=0, waiting=0) Means pool reached maximum connections limit set in configuration.
The next line: HikariPool-0 - Connection is not available, request timed out after 30000ms. Means pool waited 30000ms for free connection but your application not returned any connection meanwhile.
Mostly it is connection leak (connection is not closed after borrowing from pool), set leakDetectionThreshold to the maximum value that you expect SQL query would take to execute.
otherwise, your maximum connections 'at a time' requirement is higher than 20 !

If you want to scan to the end of the string (stripping out a newline if there), just use:
char *x = "19 cool kid";
sscanf (x, "%d %[^\n]", &age, buffer);
That's because %s
only matches non-whitespace characters and will stop on the first whitespace it finds. The %[^\n]
format specifier will match every character that's not (because of ^
) in the selection given (which is a newline). In other words, it will match any other character.
Keep in mind that you should have allocated enough space in your buffer to take the string since you cannot be sure how much will be read (a good reason to stay away from scanf/fscanf
unless you use specific field widths).
You could do that with:
char *x = "19 cool kid";
char *buffer = malloc (strlen (x) + 1);
sscanf (x, "%d %[^\n]", &age, buffer);
(you don't need * sizeof(char)
since that's always 1 by definition).

The opacity property of the outer DIV cannot be undone by the inner DIV. If you want to achieve transparency, use rgba
or hsla
:
Outer div:
background-color: rgba(255, 255, 255, 0.9); /* Color white with alpha 0.9*/
Inner div:
background-color: #FFF; /* Background white, to override the background propery*/
EDIT
Because you've added filter:alpha(opacity=90)
to your question, I assume that you also want a working solution for (older versions of) IE. This should work (-ms-
prefix for the newest versions of IE):
/*Padded for readability, you can write the following at one line:*/
filter: progid:DXImageTransform.Microsoft.Gradient(
GradientType=1,
startColorStr="#E6FFFFFF",
endColorStr="#E6FFFFFF");
/*Similarly: */
filter: progid:DXImageTransform.Microsoft.Gradient(
GradientType=1,
startColorStr="#E6FFFFFF",
endColorStr="#E6FFFFFF");
I've used the Gradient filter, starting with the same start-
and end-color
, so that the background doesn't show a gradient, but a flat colour. The colour format is in the ARGB hex format. I've written a JavaScript snippet to convert relative opacity values to absolute alpha-hex values:
var opacity = .9;
var A_ofARGB = Math.round(opacity * 255).toString(16);
if(A_ofARGB.length == 1) A_ofARGB = "0"+a_ofARGB;
else if(!A_ofARGB.length) A_ofARGB = "00";
alert(A_ofARGB);
I've created an easy way to do this issue
DataTable newTable = oldtable.Clone();
for (int i = 0; i < oldtable.Rows.Count; i++)
{
DataRow drNew = newTable.NewRow();
drNew.ItemArray = oldtable.Rows[i].ItemArray;
newTable.Rows.Add(drNew);
}
If you're unable to change php.ini you could also point to the cacert.pem file from code like this:
$http = new GuzzleHttp\Client(['verify' => '/path/to/cacert.pem']);
$client = new Google_Client();
$client->setHttpClient($http);
System.out.println(isLeapYear);
should work just fine.
Incidentally, in
else if ((year % 4 == 0) && (year % 100 == 0)) isLeapYear = false; else if ((year % 4 == 0) && (year % 100 == 0) && (year % 400 == 0)) isLeapYear = true;
the year % 400
part will never be reached because if (year % 4 == 0) && (year % 100 == 0) && (year % 400 == 0)
is true, then (year % 4 == 0) && (year % 100 == 0)
must have succeeded.
Maybe swap those two conditions or refactor them:
else if ((year % 4 == 0) && (year % 100 == 0))
isLeapYear = (year % 400 == 0);
Easiest solution that I might have found is to create a table from the data you get from the SP. Then create a view from that:
Insert this at the last step when selecting data from the SP. SELECT * into table1 FROM #Temp
create view vw_view1 as select * from table1
Use array_shift
function
$myarray = array_shift($myarray);
This will move array elements one level up and you can access any array element without using [0]
key
echo $myarray['email'];
will show [email protected]
Clean and simple:
<form action="/myaction" method="post" target="_blank">
<!-- other elements -->
<a href="#" onclick="this.parentNode.submit();">Submit</a>
</form>
In case of opening form action
url in a new tab (target="_blank"
):
<form action="/myaction" method="post" target="_blank">
<!-- other elements -->
<a href="#" onclick="this.parentNode.submit();">Submit</a>
</form>

Answers here are a little bit out of date, may be from vs 2008 time. Because in newer Visual Studio versions 2010/2012, this feature is already built-in. Thus there are no reason to use any extension or tools for it.
Feature to count lines of code - Calculate Metrics. With it you can calculate your metrics (LOC, Maintaince index, Cyclomatic index, Depth of inheritence) for each project or solution.
Just right click on solution or project in Solution Explorer,
and select "Calculate metrics"
Later data for analysis and aggregation could be imported to Excel. Also in Excel you can filter out generated classes, or other noise from your metrics. These metrics including Lines of code LOC could be gathered also during build process, and included in build report
Yes, according to RFC 3696 apostrophes are valid as long as they come before the @ symbol.
Please check the file "system/core/CodeIgniter.php". It is defined in const CI_VERSION = '3.1.10';
You could inject $routeParams
to your controller and access all the params that where used when the route was resolved.
E.g.:
// route was: app.dev/backend/:type/:id
function MyCtrl($scope, $routeParams, $log) {
// use the params
$log.info($routeParams.type, $routeParams.id);
};
See angular $routeParams documentation for further information.
You can use CSS to do it for example
<style>
html{
width:100%;
height:100%;
}
body{
width:100%;
height:100%;
background-color:#DDD;
}
</style>
Also in case you had node installed before nvm check in your ~/.bash_profile to not have something like :
export PATH=/bin:/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:$PATH
If you do have it, comment/remove it and nvm should start handling the default node version.

I nearly used everything in that article to create the SQLite database for my own C# Application.
Don't forget to download the SQLite.dll, and add it as a reference to your project. This can be done using NuGet and by adding the dll manually.
After you added the reference, refer to the dll from your code using the following line on top of your class:
using System.Data.SQLite;
You can find the dll's here:
You can find the NuGet way here:
Up next is the create script. Creating a database file:
SQLiteConnection.CreateFile("MyDatabase.sqlite");
SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
m_dbConnection.Open();
string sql = "create table highscores (name varchar(20), score int)";
SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
sql = "insert into highscores (name, score) values ('Me', 9001)";
command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
m_dbConnection.Close();
After you created a create script in C#, I think you might want to add rollback transactions, it is safer and it will keep your database from failing, because the data will be committed at the end in one big piece as an atomic operation to the database and not in little pieces, where it could fail at 5th of 10 queries for example.
Example on how to use transactions:
using (TransactionScope tran = new TransactionScope())
{
//Insert create script here.
//Indicates that creating the SQLiteDatabase went succesfully, so the database can be committed.
tran.Complete();
}
Casting null values is required for following construct where a method is overloaded and if null is passed to these overloaded methods then the compiler does not know how to clear up the ambiguity hence we need to typecast null in these cases:
class A {
public void foo(Long l) {
// do something with l
}
public void foo(String s) {
// do something with s
}
}
new A().foo((String)null);
new A().foo((Long)null);
Otherwise you couldn't call the method you need.

Use the string constructor which accepts chararray as argument, start position and length of array. Syntax is given below:
string charToString = new string(CharArray, 0, CharArray.Count());
Assuming not null longVal
Integer intVal = ((Number)longVal).intValue();
It works for example y you get an Object that can be an Integer or a Long. I know that is ugly, but it happens...
MouseInfo.getPointerInfo().getLocation() might be helpful. It returns a Point object corresponding to current mouse position.

The SQL Server Management Studio has implicit commit turned on, so all statements that are executed are implicitly commited.
This might be a scary thing if you come from an Oracle background where the default is to not have commands commited automatically, but it's not that much of a problem.
If you still want to use ad-hoc transactions, you can always execute
BEGIN TRANSACTION
within SSMS, and than the system waits for you to commit the data.
If you want to replicate the Oracle behaviour, and start an implicit transaction, whenever some DML/DDL is issued, you can set the SET IMPLICIT_TRANSACTIONS checkbox in
Tools -> Options -> Query Execution -> SQL Server -> ANSI
I think your assignment is backwards:
a[i] = b[i];
should be:
b[i] = a[i];
Yes it is correct. you can do it with an inner class.
There are already great methods already mentioned on this page, however it does seem a little obscure as to which to use. So I have added some mesurements so you can more easily decide for yourself:

The results show that the first method involving inbuilt methods is much faster than list comprehension.

In all cases the map(int, str(num))
is the fastest method (and is therefore probably the best method to use). List comprehension is the second fastest (but the method using map(int, str(num))
is probably the most desirable of the two.
Those that reinvent the wheel are interesting but are probably not so desirable in real use.
Since $.getJSON
is async, I think your console.log(list.length);
code is firing before your array has been populated. To correct this put your console.log
statement inside your callback:
var list = new Array();
$.getJSON("json.js", function(data) {
$.each(data, function(i, item) {
console.log(item.text);
list.push(item.text);
});
console.log(list.length);
});
The immediate problem seems to be that you're missing the psycopg2 module.
Your second attempt failed primarily because you named the CTE same as the underlying table and made the CTE look as if it was a recursive CTE, because it essentially referenced itself. A recursive CTE must have a specific structure which requires the use of the UNION ALL
set operator.
Instead, you could just have given the CTE a different name as well as added the target column to it:
With SomeName As
(
SELECT
CODE_DEST,
ROW_NUMBER() OVER (ORDER BY [RS_NOM] DESC) AS RN
FROM DESTINATAIRE_TEMP
)
UPDATE SomeName SET CODE_DEST=RN
loadXMLDoc JS function should return false, otherwise it will result in postback.
For most controls, you set its height and width to Auto
in the XAML, and it will size to fit its content.
In code, you set the width/height to double.NaN
. For details, see FrameworkElement.Width, particularly the "remarks" section.
i wrote this sp to create automatically the schema with all things, pk, fk, partitions, constraints... I wrote it to run in same sp.

Use a static AutoResetEvent in your spawned threads to call back to the main thread using the Set() method. This guy has a fairly good demo in SO on how to use it.
lista = list.sort(lista)
This should be
lista.sort()
The .sort()
method is in-place, and returns None. If you want something not in-place, which returns a value, you could use
sorted_list = sorted(lista)
Aside #1: please don't call your lists list
. That clobbers the builtin list type.
Aside #2: I'm not sure what this line is meant to do:
print str("value 1a")+str(" + ")+str("value 2")+str(" = ")+str("value 3a ")+str("value 4")+str("\n")
is it simply
print "value 1a + value 2 = value 3a value 4"
? In other words, I don't know why you're calling str on things which are already str.
Aside #3: sometimes you use print("something")
(Python 3 syntax) and sometimes you use print "something"
(Python 2). The latter would give you a SyntaxError in py3, so you must be running 2.*, in which case you probably don't want to get in the habit or you'll wind up printing tuples, with extra parentheses. I admit that it'll work well enough here, because if there's only one element in the parentheses it's not interpreted as a tuple, but it looks strange to the pythonic eye..
The exception TypeError: 'NoneType' object is not subscriptable
happens because the value of lista
is actually None
. You can reproduce TypeError
that you get in your code if you try this at the Python command line:
None[0]
The reason that lista
gets set to None is because the return value of list.sort()
is None
... it does not return a sorted copy of the original list. Instead, as the documentation points out, the list gets sorted in-place instead of a copy being made (this is for efficiency reasons).
If you do not want to alter the original version you can use
other_list = sorted(lista)
Just add a custom property to the page which will return the variable of your choice. You can then use the built-in "control" parameter type.
In the code behind, add:
Dim MyVariable as Long
ReadOnly Property MyCustomProperty As Long
Get
Return MyVariable
End Get
End Property
In the select parameters section add:
<asp:ControlParameter ControlID="__Page" Name="MyParameter"
PropertyName="MyCustomProperty" Type="Int32" />

The accepted answer work when you have a single line string(the email) but if you have a
multiline string, the error will remain.
Please look into this matter:
<!-- start: definition-->
@{
dynamic item = new System.Dynamic.ExpandoObject();
item.MultiLineString = @"a multi-line
string";
item.SingleLineString = "a single-line string";
}
<!-- end: definition-->
<a href="#" onclick="Getinfo('@item.MultiLineString')">6/16/2016 2:02:29 AM</a>
<script>
function Getinfo(text) {
alert(text);
}
</script>
Change the single-quote(') to backtick(`) in Getinfo as bellow and error will be fixed:
<a href="#" onclick="Getinfo(`@item.MultiLineString`)">6/16/2016 2:02:29 AM</a>
This page contains all the cached urls
chrome://cache
Unfortunately to actually see the file you have to select everything on the page and paste it in this tool: http://www.sensefulsolutions.com/2012/01/viewing-chrome-cache-easy-way.html
Quick solution I found was inside the pgAdmin program for windows. Under Tools menu there is a "Query Tool". Inside the Query Tool there is a Graphical Query Builder that can quickly show the database tables details. Good for a basic view
Another working solution for those who were blocked with jQuery trigger handler, that dosent fire on native events will be like below (100% working) :
var sortBySelect = document.querySelector("select.your-class");
sortBySelect.value = "new value";
sortBySelect.dispatchEvent(new Event("change"));
From the api on GridLayout:
The container is divided into equal-sized rectangles, and one component is placed in each rectangle.
Try using FlowLayout or GridBagLayout for your set size to be meaningful. Also, @Serplat is correct. You need to use setPreferredSize( Dimension ) instead of setSize( int, int ).
JPanel displayPanel = new JPanel();
// JPanel displayPanel = new JPanel( new GridLayout( 4, 2 ) );
// JPanel displayPanel = new JPanel( new BorderLayout() );
// JPanel displayPanel = new JPanel( new GridBagLayout() );
JTextField titleText = new JTextField( "title" );
titleText.setPreferredSize( new Dimension( 200, 24 ) );
// For FlowLayout and GridLayout, uncomment:
displayPanel.add( titleText );
// For BorderLayout, uncomment:
// displayPanel.add( titleText, BorderLayout.NORTH );
// For GridBagLayout, uncomment:
// displayPanel.add( titleText, new GridBagConstraints( 0, 0, 1, 1, 1.0,
// 1.0, GridBagConstraints.CENTER, GridBagConstraints.NONE,
// new Insets( 0, 0, 0, 0 ), 0, 0 ) );
By default, gcc selects the language based on the file extension, but you can force gcc to select a different language backend with the -x option thus:
gcc -x c++
More options are detailed in the gcc man page under "Options controlling the kind of output". See e.g. http://linux.die.net/man/1/gcc (search on the page for the text -x language
).
This facility is very useful in cases where gcc can't guess the language using a file extension, for example if you're generating code and feeding it to gcc via stdin.
Following is working for me on dotnet 1.0.1:
./ourView.cshtml
@Html.Partial(
"_ourPartial.cshtml",
new ViewDataDictionary(this.Vi??ewData) {
{
"hi", "hello"
}
}
);
./_ourPartial.cshtml
<h1>@this.ViewData["hi"]</h1>
Clear:both gives you that space between them.
For example your code:
<div style="float:left">Hello</div>
<div style="float:right">Howdy dere pardner</div>
Will currently display as :
Hello ................... Howdy dere pardner
If you add the following to above snippet,
<div style="clear:both"></div>
In between them it will display as:
Hello ................
Howdy dere pardner
giving you that space between hello and Howdy dere pardner.

In my case previous version was 3.2. I have upgraded to 3.6 but data files was not compatible to new version so I removed all data files as it was not usable for me and its works.
You can check logs using /var/log/mongodb
Note: This solution only works for Webkit browsers, which incorrectly apply pseudo-elements to self-closing tags.
As an addendum to above answers it is worth noting that in some cases one needs to insert a space instead of merely ignoring <br>
:
For instance the above answers will turn
Monday<br>05 August
to
Monday05 August
as I had verified while I tried to format my weekly event calendar. A space after "Monday" is preferred to be inserted. This can be done easily by inserting the following in the CSS:
br {
content: ' '
}
br:after {
content: ' '
}
This will make
Monday<br>05 August
look like
Monday 05 August
You can change the content
attribute in br:after
to ', '
if you want to separate by commas, or put anything you want within ' '
to make it the delimiter! By the way
Monday, 05 August
looks neat ;-)
See here for a reference.
As in the above answers, if you want to make it tag-specific, you can. As in if you want this property to work for tag <h3>
, just add a h3
each before br
and br:after
, for instance.
It works most generally for a pseudo-tag.
Another option like Gavin Palmer answer is to use the .pem
file but with a curl option
download the last updated .pem
file from https://curl.haxx.se/docs/caextract.html and save it somewhere on your server(outside the public folder)
set the option in your code instead of the php.ini
file.
In your code
curl_setopt($ch, CURLOPT_CAINFO, $_SERVER['DOCUMENT_ROOT'] . "/../cacert-2017-09-20.pem");
NOTE: setting the cainfo in the php.ini
like @Gavin Palmer did is better than setting it in your code like I did, because it will save a disk IO every time the function is called, I just make it like this in case you want to test the cainfo file on the fly instead of changing the php.ini
while testing your function.
its kind of hacky but it works well-ish
function close_frame(){
if(!window.should_close){
window.should_close=1;
}else if(window.should_close==1){
location.reload();
//or iframe hide or whatever
}
}
<iframe src="iframe_index.php" onload="close_frame()"></iframe>
then inside the frame
$('#close_modal_main').click(function(){
window.location = 'iframe_index.php?close=1';
});
and if you want to get fancy through a
if(isset($_GET['close'])){
die;
}
at the top of your frame page to make that reload unnoticeable
so basically the first time the frame loads it doesnt hide itself but the next time it loads itll call the onload function and the parent will have a the window var causing the frame to close
I think what you're looking for is an IP Geolocation database or service provider. There are many out there and some are free (get what you pay for).
Although I haven't used this service before, it claims to be in real-time. https://kickfire.com/kf-api
Here's another IP geo location API from Abstract API - https://www.abstractapi.com/ip-geolocation-api
But just do a google search on IP geo and you'll get more results than you need.

Since the code suggested by @Pascal is deprecated as mentioned by @Jacob, I found this another way that works for me.
import org.hibernate.classic.Session;
import org.hibernate.connection.ConnectionProvider;
import org.hibernate.engine.SessionFactoryImplementor;
Session session = (Session) em.getDelegate();
SessionFactoryImplementor sfi = (SessionFactoryImplementor) session.getSessionFactory();
ConnectionProvider cp = sfi.getConnectionProvider();
Connection connection = cp.getConnection();
Just to rule out the possibility you aren't actually trying to see the fragment on a GET/POST and actually want to know how to access that part of a URI object you have within your server-side code, it is under Uri.Fragment (MSDN docs).
Given an answer as high voted and views. I did find the answer with mixed of here and other links.
I have a scenario where all patient-related menu is disabled if a patient is not selected. (Refer link - how to disable a li tag using JavaScript)
//css
.disabled{
pointer-events:none;
opacity:0.4;

$("li a").addClass('disabled');
// remove .disabled when you are done
So rather than write long code, I found an interesting solution via CSS.

//var PatientId =1; //remove to test enable i.e. patient selected_x000D_

I was in exactly the same situation recently, mate, and I can tell you what I did.
Josh Smith "WPF Apps With The Model-View-ViewModel Design Pattern" read again, again and again :-) download the code, examine, compile and keep it around
No real start-to-finish tutorials, sorry...
In Java 8, I use simple helper methods like this:
public static <T> Collection<T> getIntersection(Collection<T> coll1, Collection<T> coll2){
return Stream.concat(coll1.stream(), coll2.stream())
.filter(coll1::contains)
.filter(coll2::contains)
.collect(Collectors.toSet());
}
public static <T> Collection<T> getMinus(Collection<T> coll1, Collection<T> coll2){
return coll1.stream().filter(not(coll2::contains)).collect(Collectors.toSet());
}
public static <T> Predicate<T> not(Predicate<T> t) {
return t.negate();
}
