Ensure Script Debugging is disabled
I was getting this intermittently despite having tried several of the above suggestions. As soon as I disabled this, my debugging my site worked like a dream. (Think I'd only turned it on by accident, or perhaps in a previous life).
When use CMS GC in jdk1.8 will appeare this error, i change the G1 Gc solve this problem.

Have you tried using the [FromUri]
attribute when sending parameters over the query string.
Here is an example:
[HttpGet]
[Route("api/department/getndeptsfromid")]
public List<Department> GetNDepartmentsFromID([FromUri]int FirstId, [FromUri] int CountToFetch)
{
return HHSService.GetNDepartmentsFromID(FirstId, CountToFetch);
}
Include this package at the top also, using System.Web.Http;
Whenever a TypeInitializationException
is thrown, check all initialization logic of the type you are referring to for the first time in the statement where the exception is thrown - in your case: Logger
.
Initialization logic includes: the type's static constructor (which - if I didn't miss it - you do not have for Logger
) and field initialization.
Field initialization is pretty much "uncritical" in Logger
except for the following lines:
private static string s_bstCommonAppData = Path.Combine(s_commonAppData, "XXXX");
private static string s_bstUserDataDir = Path.Combine(s_bstCommonAppData, "UserData");
private static string s_commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);
s_commonAppData
is null
at the point where Path.Combine(s_commonAppData, "XXXX");
is called. As far as I'm concerned, these initializations happen in the exact order you wrote them - so put s_commonAppData
up by at least two lines ;)
This means that you already have a MySQL database running at port 3306.
In the XAMPP control panel, press the 'Config' button and after that press 'my.ini'. After this, Ctrl-F and search for '3306'. Replace any '3306' that you find with a different port number of your choice (you could choose 3307 or 3308 - I chose 2811 and it worked).
After you have replaced every location where '3306' is written, save the file and press 'Start' on the control panel again.
Based on this questions answer I implemented a class you can use to read a file synchronously line-by-line with fs.readSync()
. You can make this "pause" and "resume" by using a Q
promise (jQuery
seems to require a DOM so cant run it with nodejs
):
var fs = require('fs');
var Q = require('q');
var lr = new LineReader(filenameToLoad);
lr.open();
var promise;
workOnLine = function () {
var line = lr.readNextLine();
promise = complexLineTransformation(line).then(
function() {console.log('ok');workOnLine();},
function() {console.log('error');}
);
}
workOnLine();
complexLineTransformation = function (line) {
var deferred = Q.defer();
// ... async call goes here, in callback: deferred.resolve('done ok'); or deferred.reject(new Error(error));
return deferred.promise;
}
function LineReader (filename) {
this.moreLinesAvailable = true;
this.fd = undefined;
this.bufferSize = 1024*1024;
this.buffer = new Buffer(this.bufferSize);
this.leftOver = '';
this.read = undefined;
this.idxStart = undefined;
this.idx = undefined;
this.lineNumber = 0;
this._bundleOfLines = [];
this.open = function() {
this.fd = fs.openSync(filename, 'r');
};
this.readNextLine = function () {
if (this._bundleOfLines.length === 0) {
this._readNextBundleOfLines();
}
this.lineNumber++;
var lineToReturn = this._bundleOfLines[0];
this._bundleOfLines.splice(0, 1); // remove first element (pos, howmany)
return lineToReturn;
};
this.getLineNumber = function() {
return this.lineNumber;
};
this._readNextBundleOfLines = function() {
var line = "";
while ((this.read = fs.readSync(this.fd, this.buffer, 0, this.bufferSize, null)) !== 0) { // read next bytes until end of file
this.leftOver += this.buffer.toString('utf8', 0, this.read); // append to leftOver
this.idxStart = 0
while ((this.idx = this.leftOver.indexOf("\n", this.idxStart)) !== -1) { // as long as there is a newline-char in leftOver
line = this.leftOver.substring(this.idxStart, this.idx);
this._bundleOfLines.push(line);
this.idxStart = this.idx + 1;
}
this.leftOver = this.leftOver.substring(this.idxStart);
if (line !== "") {
break;
}
}
};
}

In my case, the application pool had stopped. Starting it fixed the problem.
My website is hosted on Arvixe. The error problem probably occurred because I have membership based application and something bad happened when I was upload files.
I figured out a way to telnet to a server and change a file permission. Then FTP the file back to your computer and open it. Hopefully this will answer your questions and also help FTP.
The filepath variable is setup so you always login and cd to the same directory. You can change it to a prompt so the user can enter it manually.
:: This will telnet to the server, change the permissions,
:: download the file, and then open it from your PC.
:: Add your username, password, servername, and file path to the file.
:: I have not tested the server name with an IP address.
:: Note - telnetcmd.dat and ftpcmd.dat are temp files used to hold commands
@echo off
SET username=
SET password=
SET servername=
SET filepath=
set /p id="Enter the file name: " %=%
echo user %username%> telnetcmd.dat
echo %password%>> telnetcmd.dat
echo cd %filepath%>> telnetcmd.dat
echo SITE chmod 777 %id%>> telnetcmd.dat
echo exit>> telnetcmd.dat
telnet %servername% < telnetcmd.dat
echo user %username%> ftpcmd.dat
echo %password%>> ftpcmd.dat
echo cd %filepath%>> ftpcmd.dat
echo get %id%>> ftpcmd.dat
echo quit>> ftpcmd.dat
ftp -n -s:ftpcmd.dat %servername%
del ftpcmd.dat

I wasted three hours of my time on it.
All seem overly complicated! Or am I missing something?
Surely all you need is something like:
select d.name, case when m.type = 0 then 'Data' else 'Log' end, m.size * 8 / 1024
from sys.master_files m JOIN sys.databases d ON d.database_id = m.database_id
or if you don't want the log:
select d.name, m.size * 8 / 1024
from sys.master_files m JOIN sys.databases d ON d.database_id = m.database_id and m.type =0
Try invoking your command with Invoke-Expression
:
Invoke-Expression $cmd1
Here is a working example on my machine:
$cmd = "& 'C:\Program Files\7-zip\7z.exe' a -tzip c:\temp\test.zip c:\temp\test.txt"
Invoke-Expression $cmd
iex
is an alias for Invoke-Expression
so you could do:
iex $cmd1

Good Luck...
I assume you're asking about combinations in combinatorial sense (that is, order of elements doesn't matter, so [1 2 3]
is the same as [2 1 3]
). The idea is pretty simple then, if you understand induction / recursion: to get all K
-element combinations, you first pick initial element of a combination out of existing set of people, and then you "concatenate" this initial element with all possible combinations of K-1
people produced from elements that succeed the initial element.
As an example, let's say we want to take all combinations of 3 people from a set of 5 people. Then all possible combinations of 3 people can be expressed in terms of all possible combinations of 2 people:
comb({ 1 2 3 4 5 }, 3) =
{ 1, comb({ 2 3 4 5 }, 2) } and
{ 2, comb({ 3 4 5 }, 2) } and
{ 3, comb({ 4 5 }, 2) }
Here's C++ code that implements this idea:
#include <iostream>
#include <vector>
using namespace std;
vector<int> people;
vector<int> combination;
void pretty_print(const vector<int>& v) {
static int count = 0;
cout << "combination no " << (++count) << ": [ ";
for (int i = 0; i < v.size(); ++i) { cout << v[i] << " "; }
cout << "] " << endl;
}
void go(int offset, int k) {
if (k == 0) {
pretty_print(combination);
return;
}
for (int i = offset; i <= people.size() - k; ++i) {
combination.push_back(people[i]);
go(i+1, k-1);
combination.pop_back();
}
}
int main() {
int n = 5, k = 3;
for (int i = 0; i < n; ++i) { people.push_back(i+1); }
go(0, k);
return 0;
}
And here's output for N = 5, K = 3
:
combination no 1: [ 1 2 3 ]
combination no 2: [ 1 2 4 ]
combination no 3: [ 1 2 5 ]
combination no 4: [ 1 3 4 ]
combination no 5: [ 1 3 5 ]
combination no 6: [ 1 4 5 ]
combination no 7: [ 2 3 4 ]
combination no 8: [ 2 3 5 ]
combination no 9: [ 2 4 5 ]
combination no 10: [ 3 4 5 ]
This doesn't work because NaN
isn't equal to anything, including NaN
. Use pd.isnull(df.var2)
instead.
Here is the code that worked for me:
public ArrayList GetBBGroups(WindowsIdentity identity)
{
ArrayList groups = new ArrayList();
try
{
String userName = identity.Name;
int pos = userName.IndexOf(@"\");
if (pos > 0) userName = userName.Substring(pos + 1);
PrincipalContext domain = new PrincipalContext(ContextType.Domain, "riomc.com");
UserPrincipal user = UserPrincipal.FindByIdentity(domain, IdentityType.SamAccountName, userName);
DirectoryEntry de = new DirectoryEntry("LDAP://RIOMC.com");
DirectorySearcher search = new DirectorySearcher(de);
search.Filter = "(&(objectClass=group)(member=" + user.DistinguishedName + "))";
search.PropertiesToLoad.Add("samaccountname");
search.PropertiesToLoad.Add("cn");
String name;
SearchResultCollection results = search.FindAll();
foreach (SearchResult result in results)
{
name = (String)result.Properties["samaccountname"][0];
if (String.IsNullOrEmpty(name))
{
name = (String)result.Properties["cn"][0];
}
GetGroupsRecursive(groups, de, name);
}
}
catch
{
// return an empty list...
}
return groups;
}
public void GetGroupsRecursive(ArrayList groups, DirectoryEntry de, String dn)
{
DirectorySearcher search = new DirectorySearcher(de);
search.Filter = "(&(objectClass=group)(|(samaccountname=" + dn + ")(cn=" + dn + ")))";
search.PropertiesToLoad.Add("memberof");
String group, name;
SearchResult result = search.FindOne();
if (result == null) return;
group = @"RIOMC\" + dn;
if (!groups.Contains(group))
{
groups.Add(group);
}
if (result.Properties["memberof"].Count == 0) return;
int equalsIndex, commaIndex;
foreach (String dn1 in result.Properties["memberof"])
{
equalsIndex = dn1.IndexOf("=", 1);
if (equalsIndex > 0)
{
commaIndex = dn1.IndexOf(",", equalsIndex + 1);
name = dn1.Substring(equalsIndex + 1, commaIndex - equalsIndex - 1);
GetGroupsRecursive(groups, de, name);
}
}
}
I measured it's performance in a loop of 200 runs against the code that uses the AttributeValuesMultiString
recursive method; and it worked 1.3 times faster.
It might be so because of our AD settings. Both snippets gave the same result though.
table {
border-collapse: collapse;
}
If it is a the end of the string, you can also use chomp
:
"hello".chomp("llo") #=> "he"
In the case you need to manually 'exit' a transaction through code (be it through an exception or simply checking an error state) you shouldn't use DB::transaction()
but instead wrap your code in DB::beginTransaction
and DB::commit
/DB::rollback()
:
DB::beginTransaction();
try {
DB::insert(...);
DB::insert(...);
DB::insert(...);
DB::commit();
// all good
} catch (\Exception $e) {
DB::rollback();
// something went wrong
}
See the transaction docs.
For mac users (HighSierra), do not install node using brew. It'll mess up with npm. I had to uninstall node and install using the package in the main nodejs.org source : https://nodejs.org/en/
Here's a simple guide that doesn't use brew: https://coolestguidesontheplanet.com/installing-node-js-on-macos/
Floating point numbers in C use IEEE 754 encoding.
This type of encoding uses a sign, a significand, and an exponent.
Because of this encoding, many numbers will have small changes to allow them to be stored.
Also, the number of significant digits can change slightly since it is a binary representation, not a decimal one.
Single precision (float) gives you 23 bits of significand, 8 bits of exponent, and 1 sign bit.
Double precision (double) gives you 52 bits of significand, 11 bits of exponent, and 1 sign bit.
You might have to use another batch file first to launch the second with admin rights.
In the first use
runas /noprofile /user:mymachine\administrator yourbatchfile.bat
Upon further reading, you must be able to type in the password at the prompt. You cannot pipe the password as this feature was locked down for security reasons.
You may have more luck with psexec.
For me shutil.copy is the best:
import shutil
#make a copy of the invoice to work with
src="invoice.pdf"
dst="copied_invoice.pdf"
shutil.copy(src,dst)
You can change the path of the files as you want.
i would recommend using this:
background-repeat:no-repeat;
background-image: url(your file location here);
background-size:cover;(will only work with css3)
hope it helps :D
And if this doesnt support your needs just say it: i can make a jquery for multibrowser support.
SqlBulkCopy class is best for SQL server,
Doing Bulk Upload/Insert of DataTable to a Table in SQL server in C#
if(values >= 0) {
// as zero is more likely positive than negative
} else {
}
Made a format function that takes either a collection or an array as arguments
Usage:
format("i can speak {language} since i was {age}",{language:'javascript',age:10});
format("i can speak {0} since i was {1}",'javascript',10});
Code:
var format = function (str, col) {
col = typeof col === 'object' ? col : Array.prototype.slice.call(arguments, 1);
return str.replace(/\{\{|\}\}|\{(\w+)\}/g, function (m, n) {
if (m == "{{") { return "{"; }
if (m == "}}") { return "}"; }
return col[n];
});
};
In below deep(data,key)
function, you can use arbitrary key
string - in your case items[1].name
(you can use array notation [i]
at any level) - if key is invalid then undefined is return.
let deep = (o,k) => k.split('.').reduce((a,c,i) => {_x000D_
let m=c.match(/(.*?)\[(\d*)\]/);_x000D_
if(m && a!=null && a[m[1]]!=null) return a[m[1]][+m[2]];_x000D_
return a==null ? a: a[c];_x000D_
},o);_x000D_
_x000D_
// TEST_x000D_
_x000D_
let key = 'items[1].name' // arbitrary deep-key_x000D_
_x000D_
let data = {_x000D_
code: 42,_x000D_
items: [{ id: 11, name: 'foo'}, { id: 22, name: 'bar'},]_x000D_
};_x000D_
_x000D_
console.log( key,'=', deep(data,key) );
_x000D_
InetAddress.getByName also works for ip address.
From the JavaDoc
The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address. If a literal IP address is supplied, only the validity of the address format is checked.
I would suggest using the functions below since the ones mentioned by @bigh_29 transforms my guids into new ones (for reasons I don't understand). Also, these are a little bit faster in the tests I did on my tables. https://gist.github.com/damienb/159151

Here's a more robust routine to cancel default behavior and event bubbling in all browsers:
// Prevents event bubble up or any usage after this is called.
eventCancel = function (e)
{
if (!e)
if (window.event) e = window.event;
else return;
if (e.cancelBubble != null) e.cancelBubble = true;
if (e.stopPropagation) e.stopPropagation();
if (e.preventDefault) e.preventDefault();
if (window.event) e.returnValue = false;
if (e.cancel != null) e.cancel = true;
}
An example of how this would be used in an event handler:
// Handles the click event for each tab
Tabstrip.tabstripLinkElement_click = function (evt, context)
{
// Find the tabStrip element (we know it's the parent element of this link)
var tabstripElement = this.parentNode;
Tabstrip.showTabByLink(tabstripElement, this);
return eventCancel(evt);
}
Your problem is that log4j has not been initialized. It does not affect the outcome of you application in any way, so it's safe to ignore or just initialize Log4J, see: How to initialize log4j properly?
Here's a more valid way which also check if your textbox is filled with only blanks.

if (string.IsNullOrEmpty(txtBox1.Text) || string.IsNullOrEmpty(txtBox2.Text))
//...give error...
The edited answer of @Habib.OSU is also fine, this is just another approach.
Breadth first is a queue, depth first is a stack.
For breadth first, add all children to the queue, then pull the head and do a breadth first search on it, using the same queue.
For depth first, add all children to the stack, then pop and do a depth first on that node, using the same stack.
Updated version of @Alaaedeen's answer. You can specify any part of the version of any package you want to install. This may cause other package versions to change. For example, if you don't care about which specific version of PyQt4 you want, do:
conda install pyqt=4
This would install the latest minor version and release of PyQt 4. You can specify any portion of the version that you want, not just the major number. So, for example
conda install pyqt=4.11
would install the latest (or last) release of version 4.11.
Keep in mind that installing a different version of a package may cause the other packages that depend on it to be rolled forward or back to where they support the version you want.
You can pass the necessary variables from the parent scope into the closure with the use
keyword.
For example:
DB::table('users')->where(function ($query) use ($activated) {
$query->where('activated', '=', $activated);
})->get();
More on that here.
PHP 7.4 (will be released at November 28, 2019) introduces a shorter variation of the anonymous functions called arrow functions which makes this a bit less verbose.
An example using PHP 7.4 which is functionally nearly equivalent (see the 3rd bullet point below):
DB::table('users')->where(fn($query) => $query->where('activated', '=', $activated))->get();
Differences compared to the regular syntax:
fn
keyword instead of function
.use
keyword in the latter example.void
return type when declaring them.return
keyword must be omitted.using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

If you have a .nupkg file and just need the .dll file all you have to do is change the extension to .zip and find the lib directory.
Session.Abandon()
this will destroy the data.
Note, this won't necessarily truly remove the session token from a user, and that same session token at a later point might get picked up and created as a new session with the same id because it's deemed to be fair game to be used.
Just for history:
Check that all mentioned less/css files in bundle have Build Action = "Content".
There is no error if some files from bundle missing on destination server.
Also remember one thing. Very important
You have to specify the command something like this to be more precise
grep -l "pattern" *
A common solution is to upgrade magento setup by running this command
php bin/magento setup:upgrade && php bin/magento setup:di:compile
Otherwise just check var/report/{error number}
This is more of a maths problem than a java problem basically.
The result you receive is correct. This because 225 seconds is 3 minutes (when doing an integral division). What you want is the this:
or in java:
int millis = diff % 1000;
diff/=1000;
int seconds = diff % 60;
diff/=60;
int minutes = diff % 60;
diff/=60;
hours = diff;
Here is the unpowerful official command:
npm view <PACKAGE> dependencies
It prints only the direct dependencies, not the whole tree.
ShortcutBadger is a library that adds an abstraction layer over the device brand and current launcher and offers a great result. Works with LG, Sony, Samsung, HTC and other custom Launchers.
It even has a way to display Badge Count in Pure Android devices desktop.
Updating the Badge Count in the application icon is as easy as calling:
int badgeCount = 1;
ShortcutBadger.applyCount(context, badgeCount);
It includes a demo application that allows you to test its behavior.
To insert into only one column, use only one piece of data:
INSERT INTO Data ( Col1 ) VALUES
('Hello World');
Alternatively, to insert multiple records, separate the inserts:
INSERT INTO Data ( Col1 ) VALUES
('Hello'),
('World');
It turned out that my problem was that I was using a load balancer to handle the SSL, which then sent it over http to the actual server, which then complained.
Description of a fix is here: http://blog.hackedbrain.com/2006/09/26/how-to-ssl-passthrough-with-wcf-or-transportwithmessagecredential-over-plain-http/
Edit: I fixed my problem, which was slightly different, after talking to microsoft support.
My silverlight app had its endpoint address in code going over https to the load balancer. The load balancer then changed the endpoint address to http and to point to the actual server that it was going to. So on each server's web config I added a listenUri for the endpoint that was http instead of https
<endpoint address="" listenUri="http://[LOAD_BALANCER_ADDRESS]" ... />
The Event type input
did not work for me on <select>
but changing it to change
works
useEffect(() => {
var event = new Event('change', { bubbles: true });
selectRef.current.dispatchEvent(event); // ref to the select control
}, [props.items]);
var query = source.GroupBy(x => new { x.Column1, x.Column2 });
You have to set a default value.
ALTER TABLE mytable ADD COLUMN mycolumn character varying(50) NOT NULL DEFAULT 'foo';
... some work (set real values as you want)...
ALTER TABLE mytable ALTER COLUMN mycolumn DROP DEFAULT;
You use the datetime.datetime.date()
method:
datetime.datetime.now().date()
Obviously, the expression above can (and should IMHO :) be written as:
datetime.date.today()
Don't worry. But you should still use the second solution (plus an extra check for none of those variables existing), because there are security issues with $_REQUEST
(since $_GET
and $_POST
aren't the only sources for that array).
There was a post about the problems with $_REQUEST
yesterday, I believe. Let me go find it.
EDIT: Oh well, not directly a post, but here it is anyway: http://kuza55.blogspot.com/2006/03/request-variable-fixation.html

The easiest way to compare dates in javascript is to first convert it to a Date object and then compare these date-objects.
Below you find an object with three functions:
dates.compare(a,b)
Returns a number:
dates.inRange (d,start,end)
Returns a boolean or NaN:
dates.convert
Used by the other functions to convert their input to a date object. The input can be
.
// Source: http://stackoverflow.com/questions/497790
var dates = {
convert:function(d) {
// Converts the date in d to a date-object. The input can be:
// a date object: returned without modification
// an array : Interpreted as [year,month,day]. NOTE: month is 0-11.
// a number : Interpreted as number of milliseconds
// since 1 Jan 1970 (a timestamp)
// a string : Any format supported by the javascript engine, like
// "YYYY/MM/DD", "MM/DD/YYYY", "Jan 31 2009" etc.
// an object : Interpreted as an object with year, month and date
// attributes. **NOTE** month is 0-11.
return (
d.constructor === Date ? d :
d.constructor === Array ? new Date(d[0],d[1],d[2]) :
d.constructor === Number ? new Date(d) :
d.constructor === String ? new Date(d) :
typeof d === "object" ? new Date(d.year,d.month,d.date) :
NaN
);
},
compare:function(a,b) {
// Compare two dates (could be of any type supported by the convert
// function above) and returns:
// -1 : if a < b
// 0 : if a = b
// 1 : if a > b
// NaN : if a or b is an illegal date
// NOTE: The code inside isFinite does an assignment (=).
return (
isFinite(a=this.convert(a).valueOf()) &&
isFinite(b=this.convert(b).valueOf()) ?
(a>b)-(a<b) :
NaN
);
},
inRange:function(d,start,end) {
// Checks if date in d is between dates in start and end.
// Returns a boolean or NaN:
// true : if d is between start and end (inclusive)
// false : if d is before start or after end
// NaN : if one or more of the dates is illegal.
// NOTE: The code inside isFinite does an assignment (=).
return (
isFinite(d=this.convert(d).valueOf()) &&
isFinite(start=this.convert(start).valueOf()) &&
isFinite(end=this.convert(end).valueOf()) ?
start <= d && d <= end :
NaN
);

It's worth noting that you must open project folder in Visual Studio Code for the debugger to work. I lost few hours to make it work while having only individual file opened in the editor.
Issue explained here
IMHO, the proper way to resolve this error is to configure your global git config file.
To do that run the following command: git config --global -e
An editor will appear where you can insert your default git configurations.
Here're are a few:
[user]
name = your_username
email = [email protected]
[alias]
# BASIC
st = status
ci = commit
br = branch
co = checkout
df = diff
For more details, see Customizing Git - Git Configuration
When you see a command like, git config
...
$ git config --global core.whitespace \
trailing-space,space-before-tab,indent-with-non-tab
... you can put that into your global git config file as:
[core]
whitespace = space-before-tab,-indent-with-non-tab,trailing-space
For one off configurations, you can use something like git config --global user.name 'your_username'
If you don't set your git configurations globally, you'll need to do so for each and every git repo you work with locally.
The user.name and user.email settings tell git who you are, so subsequent git commit
commands will not complain, *** Please tell me who you are.
Many times, the commands git suggests you run are not what you should run. This time, the suggested commands are not bad:
$ git commit -m 'first commit'
*** Please tell me who you are.
Run
git config --global user.email "[email protected]"
git config --global user.name "Your Name"
Tip: Until I got very familiar with git, making a backup of my project file--before running the suggested git commands and exploring things I thought would work--saved my bacon on more than a few occasions.
If the first column is always the same size (including the spaces), then you can just take those characters (via LEFT
) and clean up the spaces (with RTRIM
):
SELECT RTRIM(LEFT(YourColumn, YourColumnSize))
Alternatively, you can extract the second (or third, etc.) column (using SUBSTRING
):
SELECT RTRIM(SUBSTRING(YourColumn, PreviousColumnSizes, YourColumnSize))
One benefit of this approach (especially if YourColumn
is the result of a computation) is that YourColumn
is only specified once.
When plotting a plot using matplotlib:
How to remove the box of the legend?
plt.legend(frameon=False)
How to change the color of the border of the legend box?
leg = plt.legend()
leg.get_frame().set_edgecolor('b')
How to remove only the border of the box of the legend?
leg = plt.legend()
leg.get_frame().set_linewidth(0.0)
Subclass your TabbarViewController and in ViewDidLoad put this code:
[UITabBarItem.appearance setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor darkGreyColorBT]} forState:UIControlStateNormal];
[UITabBarItem.appearance setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor nightyDarkColorBT]} forState:UIControlStateSelected];
self.tabBar.items[0].image = [[UIImage imageNamed:@"ic-pack [email protected]"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
self.tabBar.items[0].selectedImage = [[UIImage imageNamed:@"[email protected]"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
self.tabBar.items[1].image = [[UIImage imageNamed:@"ic-sleeptracker [email protected]"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
self.tabBar.items[1].selectedImage = [[UIImage imageNamed:@"[email protected]"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
self.tabBar.items[2].image = [[UIImage imageNamed:@"ic-profile [email protected]"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
self.tabBar.items[2].selectedImage = [[UIImage imageNamed:@"[email protected]"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
This is the simplest working solution I have
Do it without service
If you are so serious about doing it with services using mediaplayer
Intent svc=new Intent(this, BackgroundSoundService.class);
startService(svc);
public class BackgroundSoundService extends Service {
private static final String TAG = null;
MediaPlayer player;
public IBinder onBind(Intent arg0) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
player = MediaPlayer.create(this, R.raw.idil);
player.setLooping(true); // Set looping
player.setVolume(100,100);
}
public int onStartCommand(Intent intent, int flags, int startId) {
player.start();
return 1;
}
public void onStart(Intent intent, int startId) {
// TO DO
}
public IBinder onUnBind(Intent arg0) {
// TO DO Auto-generated method
return null;
}
public void onStop() {
}
public void onPause() {
}
@Override
public void onDestroy() {
player.stop();
player.release();
}
@Override
public void onLowMemory() {
}
}
Please call this service in Manifest Make sure there is no space at the end of the .BackgroundSoundService string
<service android:enabled="true" android:name=".BackgroundSoundService" />
You cannot delete everything with either rmdir
or del
alone:
rmdir /s /q
does not accept wildcard params. So rmdir /s /q *
will error.del /s /f /q
will delete all files, but empty subdirectories will remain.My preferred solution (as I have used in many other batch files) is:
rmdir /s /q . 2>NUL
with 'exists?':
Business.exists? user_id: current_user.id #=> 1 or nil
with 'any?':
Business.where(:user_id => current_user.id).any? #=> true or false
If you use something with .where, be sure to avoid trouble with scopes and better use .unscoped
Business.unscoped.where(:user_id => current_user.id).any?
Not sure if this is a feature or a bug but this worked for us:
git commit '' -m "Message"
Note the empty file list ''. Git interprets this to commit all modified tracked files, even if they are not staged, and ignore untracked files.
As described by Herb Sutter and Scott Meyers, prefer non-friend non-member functions to member functions, to help increase encapsulation.
In some cases, like C++ streams, you won't have the choice and must use non-member functions.
But still, it does not mean you have to make these functions friends of your classes: These functions can still acess your class through your class accessors. If you succeed in writting those functions this way, then you won.
I believe the examples you gave in your question are wrong. For example;
ostream & operator<<(ostream &os) {
return os << paragraph;
}
I can't even start to think how this method could work in a stream.
Here are the two ways to implement the << and >> operators.
Let's say you want to use a stream-like object of type T.
And that you want to extract/insert from/into T the relevant data of your object of type Paragraph.
The first being as functions:
// T << Paragraph
T & operator << (T & p_oOutputStream, const Paragraph & p_oParagraph)
{
// do the insertion of p_oParagraph
return p_oOutputStream ;
}
// T >> Paragraph
T & operator >> (T & p_oInputStream, const Paragraph & p_oParagraph)
{
// do the extraction of p_oParagraph
return p_oInputStream ;
}
The second being as methods:
// T << Paragraph
T & T::operator << (const Paragraph & p_oParagraph)
{
// do the insertion of p_oParagraph
return *this ;
}
// T >> Paragraph
T & T::operator >> (const Paragraph & p_oParagraph)
{
// do the extraction of p_oParagraph
return *this ;
}
Note that to use this notation, you must extend T's class declaration. For STL objects, this is not possible (you are not supposed to modify them...).
Here are the prototypes of the same << and >> operators for C++ streams.
Note that is case of streams, as you can't modify the C++ stream, you must implement the functions. Which means something like:
// OUTPUT << Paragraph
template <typename charT, typename traits>
std::basic_ostream<charT,traits> & operator << (std::basic_ostream<charT,traits> & p_oOutputStream, const Paragraph & p_oParagraph)
{
// do the insertion of p_oParagraph
return p_oOutputStream ;
}
// INPUT >> Paragraph
template <typename charT, typename traits>
std::basic_istream<charT,traits> & operator >> (std::basic_istream<charT,traits> & p_oInputStream, const CMyObject & p_oParagraph)
{
// do the extract of p_oParagraph
return p_oInputStream ;
}
The following code will work only for char-based streams.
// OUTPUT << A
std::ostream & operator << (std::ostream & p_oOutputStream, const Paragraph & p_oParagraph)
{
// do the insertion of p_oParagraph
return p_oOutputStream ;
}
// INPUT >> A
std::istream & operator >> (std::istream & p_oInputStream, const Paragraph & p_oParagraph)
{
// do the extract of p_oParagraph
return p_oInputStream ;
}
Rhys Ulerich commented about the fact the char-based code is but a "specialization" of the generic code above it. Of course, Rhys is right: I don't recommend the use of the char-based example. It is only given here because it's simpler to read. As it is only viable if you only work with char-based streams, you should avoid it on platforms where wchar_t code is common (i.e. on Windows).
Hope this will help.
You could use THROW
(available in SQL Server 2012+):
THROW 50000, 'Your custom error message', 1
THROW <error_number>, <message>, <state>
# print line number 52
sed -n '52p' # method 1
sed '52!d' # method 2
sed '52q;d' # method 3, efficient on large files
method 3 efficient on large files
fastest way to display specific lines
You could also use the php native funcion get_browser()
IMPORTANT NOTE: You should have a browscap.ini file.
Close android studio and open it again. Then try compiling the same code. I was getting the same error and it worked for me. Hope it helps.
Weird issue, but this helped me to solve my issue. Sometimes even the easiest things are hard to figure out...
Instead of using
/js/main.css
in my script-tag I used js/main.css
YES, it did actually make a difference. I'm sitting on WAMP / Windows and I didn't have a vhost but just used localhost/<project>
If I reference to /js/main.css
then I reference to localhost/css/main.css
and not to localhost/<project>/css/main.css
When you think of it, it's quite obvious but if someone stumbles upon this I thought I would share this answer.
Always use static in .c
files unless you need to reference the object from a different .c
module.
Never use static in .h
files, because you will create a different object every time it is included.
I faced the same error with my Visual Studio Team Services account (formerly Visual Studio Online, Team Foundation Service).
I simply entered the credentials using the VS 2013 "Connect to Team Foundation Server" Window, and then connected it to the Visual Studio Team Services Team Project. It worked this way.
I wrote this pattern:
Pattern SPECIAL_REGEX_CHARS = Pattern.compile("[{}()\\[\\].+*?^$\\\\|]");
And use it in this method:
String escapeSpecialRegexChars(String str) {
return SPECIAL_REGEX_CHARS.matcher(str).replaceAll("\\\\$0");
}
Then you can use it like this, for example:
Pattern toSafePattern(String text)
{
return Pattern.compile(".*" + escapeSpecialRegexChars(text) + ".*");
}
We needed to do that because, after escaping, we add some regex expressions. If not, you can simply use \Q
and \E
:
Pattern toSafePattern(String text)
{
return Pattern.compile(".*\\Q" + text + "\\E.*")
}
events
for an HTML element
on the developer console
:events
we want to capture:$(document).on('ch-ui-container-closed ch-ui-container-opened', function(evt){
console.log(evt);
});
Good Luck...
That's invalid Javascript syntax; a property name cannot have a -

Ruby seems to provide a poor solution. To explain, start with a simple C++ example that shows access to private class methods:
#include <iostream>
class C
{
public:
void instance_method(void)
{
std::cout << "instance method\n";
class_method(); // !!! LOOK !!! no 'send' required. We can access it
// because 'private' allows access within the class
}
private:
void static class_method(void) { std::cout << "class method\n"; }
};
int main()
{
C c;
c.instance_method(); // works
// C::class_method() does not compile - it's properly private
return 0;
}
Running the above
% ./a.out
instance method
class method
Now Ruby does not seem to provide the equivalent. Ruby's rules, I think, are that private methods must not be accessed with a receiver. That is,
inst.pvt_method # FAILS
pvt_method # WORKS only within the class (good)
That's OK for private instance methods, but causes problems with private class methods.
I would like Ruby to function this way:
class C
def instance_method
STDOUT << "instance method\n"
# Simple access to the private class method would be nice:
class_method # DOES NOT WORK. RUBY WON'T FIND THE METHOD
C.class_method # DOES NOT WORK. RUBY WON'T ALLOW IT
# ONLY THIS WORKS. While I am happy such capability exists I think
# the way 'send' should be used is when the coder knows he/she is
# doing a no-no. The semantic load on the coder for this is also
# remarkably clumsy for an elegant language like ruby.
self.class.send(:class_method)
end
private_class_method def self.class_method() STDOUT << "class method\n"; end
end
But, alas, the above does not work. Does someone know a better way?
When I see 'send' prior to a method, it's a clear sign the code is violating the intent of the API's designer, but in this case the design is specifically to have an instance method of the class call the private class method.
If you need some logical control over character removal, use this
String string = "sdsdsd";
char[] arr = string.toCharArray();
// Run loop or whatever you need
String ss = new String(arr);
If you don't need any such control, you can use what Oscar orBhesh mentioned. They are spot on.
You just make div
s like this:
<div style="width:100px; height: 100px; border:1px solid; overflow:hidden; ">
<br/>
<div style="position:inherit; width: 200px; height:200px; background:yellow;">
<br/>
<div style="position:absolute; width: 500px; height:50px; background:Pink; z-index: 99;">
<br/>
</div>
</div>
</div>
I hope this code will help you :)
There's an article over on MSDN that has a sample application for zipping and unzipping files and folders purely in C#. I've been using some of the classes in that successfully for a long time. The code is released under the Microsoft Permissive License, if you need to know that sort of thing.
EDIT: Thanks to Cheeso for pointing out that I'm a bit behind the times. The MSDN example I pointed to is in fact using DotNetZip and is really very fully-featured these days. Based on my experience of a previous version of this I'd happily recommend it.
SharpZipLib is also quite a mature library and is highly rated by people, and is available under the GPL license. It really depends on your zipping needs and how you view the license terms for each of them.

For those using Rails(4.2) Internationalization (I18n):
Set the placeholder attribute to true:
f.text_field :attr, placeholder: true
and in your local file (ie. en.yml):
en:
helpers:
placeholder:
model_name:
attr: "some placeholder text"
I have tried all the methods above but none of them could fix the same issue on my laptop. Finally instead of pushing the branch to origin in git bash, I trun to use TortoiseGit's push option to do the pushing, then a window pops-up to ask me to add the new host key to cache, after clicking the yes button, everything goes fine now.
Hope it helps to you all.
SUM
is an aggregate function. It will calculate the total for each group. +
is used for calculating two or more columns in a row.
Consider this example,
ID VALUE1 VALUE2
===================
1 1 2
1 2 2
2 3 4
2 4 5
SELECT ID, SUM(VALUE1), SUM(VALUE2)
FROM tableName
GROUP BY ID
will result
ID, SUM(VALUE1), SUM(VALUE2)
1 3 4
2 7 9
SELECT ID, VALUE1 + VALUE2
FROM TableName
will result
ID, VALUE1 + VALUE2
1 3
1 4
2 7
2 9
SELECT ID, SUM(VALUE1 + VALUE2)
FROM tableName
GROUP BY ID
will result
ID, SUM(VALUE1 + VALUE2)
1 7

sumr

:
final def sumr(implicit A: Monoid[A]): A = F.foldRight(self, A.zero)(A.append)
foldRight
is not always tail recursive, so you can overflow the stack if the collection is too long. See Why foldRight and reduceRight are NOT tail recursive? for some more discussion of when this is or isn't true.

I've run into issues with Webclient.Downloadstring before. If you do, you can try this:
WebRequest request = WebRequest.Create("http://www.google.com");
WebResponse response = request.GetResponse();

using (StreamReader sr = new StreamReader(data))

var object = {
key1 : {
name : 'xxxxxx',

},
key2 : {
name : 'yyyyyyy',
value : '200.0'
},
key3 : {
name : 'zzzzzz',
value : '500.0'
},
}
If thats how your object looks and you want to loop each name and value then I would try and do something like.
$.each(object,function(key,innerjson){
/*
key would be key1,key2,key3
innerjson would be the name and value **
*/
//Alerts and logging of the variable.
console.log(innerjson); //should show you the value
alert(innerjson.name); //Should say xxxxxx,yyyyyy,zzzzzzz
});

This is the first working version of what will be a GPS reader and data presenter. tkinter is a very fragile thing with way too few error messages. It does not put stuff up and does not tell why much of the time. Very difficult coming from a good WYSIWYG form developer. Anyway, this runs a small routine 10 times a second and presents the information on a form. Took a while to make it happen. When I tried a timer value of 0, the form never came up. My head now hurts! 10 or more times per second is good enough for me. I hope it helps someone else. Mike Morrow

Short answer:
ALTER SCHEMA new_schema TRANSFER old_schema.table_name
I can confirm that the data in the table remains intact, which is probably quite important :)
Long answer as per MSDN docs,
ALTER SCHEMA schema_name
TRANSFER [ Object | Type | XML Schema Collection ] securable_name [;]
If it's a table (or anything besides a Type or XML Schema collection), you can leave out the word Object since that's the default.
I think this will work, if you are using JodaTime:
String strDateTime = "11/15/2013 08:00:00";
DateTime dateTime = DateTime.parse(strDateTime);
DateTimeFormatter fmt = DateTimeFormat.forPattern("MM/dd/YYYY");
String strDateOnly = fmt.print(dateTime);
I got part of this from here.
awk '{ sum += $2; n++ } END { if (n > 0) print sum / n; }'
Add the numbers in $2
(second column) in sum
(variables are auto-initialized to zero by awk
) and increment the number of rows (which could also be handled via built-in variable NR). At the end, if there was at least one value read, print the average.
awk '{ sum += $2 } END { if (NR > 0) print sum / NR }'
If you want to use the shebang notation, you could write:
#!/bin/awk
{ sum += $2 }
END { if (NR > 0) print sum / NR }
You can also control the format of the average with printf()
and a suitable format ("%13.6e\n"
, for example).
You can also generalize the code to average the Nth column (with N=2
in this sample) using:
awk -v N=2 '{ sum += $N } END { if (NR > 0) print sum / NR }'
As of .NET Core 2.0, the constructor Dictionary<TKey,TValue>(IEnumerable<KeyValuePair<TKey,TValue>>)
now exists.
Very informative answer from @stej, but here is a short answer: Among other options, you have 3 simple options to format [System.DateTime] stored in a variable:
Pass the variable to the Get-Date cmdlet:
Get-Date -Format "HH:mm" $date
Use toString() method:
$date.ToString("HH:mm")
Use Composite formatting:
"{0:HH:mm}" -f $date
This error message can also be caused by SELinux. Check if SELinux is enabled with getenforce
You need to adjust SELinux to use your port and restart.
I.E.
semanage port -a -t http_port_t -p tcp 9080 2>/dev/null || semanage port -m -t http_port_t -p tcp 9080
The 'a'
parameter signifies append mode. If you don't want to use with open
each time, you can easily write a function to do it for you:
def append(txt='\nFunction Successfully Executed', file):
with open(file, 'a') as f:
f.write(txt)
If you want to write somewhere else other than the end, you can use 'r+'
†:
import os
with open(file, 'r+') as f:
f.seek(0, os.SEEK_END)
f.write("text to add")
Finally, the 'w+'
parameter grants even more freedom. Specifically, it allows you to create the file if it doesn't exist, as well as empty the contents of a file that currently exists.
Create an array with the number of items you want first and then convert the array in to a List.
int[] fakeArray = new int[10];
List<int> list = fakeArray.ToList();
Ignoring the refactoring issues, you need to understand functions and return values. You don't need a global at all. Ever. You can do this:
def rps():
# Code to determine if player wins
if player_wins:
return True
return False
Then, just assign a value to the variable outside this function like so:
player_wins = rps()
It will be assigned the return value (either True or False) of the function you just called.
After the comments, I decided to add that idiomatically, this would be better expressed thus:
def rps():
# Code to determine if player wins, assigning a boolean value (True or False)
# to the variable player_wins.
return player_wins
pw = rps()
This assigns the boolean value of player_wins
(inside the function) to the pw
variable outside the function.
The only way to control the size of stack within process is start a new Thread
. But you can also control by creating a self-calling sub Java process with the -Xss
parameter.

set the bg after loading the html(from quick tests it seems loading the html resets the bg color.. this is for 2.3).
if you're loading the html from data you already got, just doing a .postDelayed in which you just set the bg(to for example transparent) is enough..
Have you tried this?

Visual Studio Community 2015 suffices to build extensions for Python 3.5. It's free but a 6 GB download (overkill). On my computer it installed vcvarsall at C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat
For Python 3.4 you'd need Visual Studio 2010. I don't think there's any free edition. See https://matthew-brett.github.io/pydagogue/python_msvc.html
A small variation on the accepted answer.
toFixed(2)
returns a string, and you will always get two decimal places. These might be zeros. If you would like to suppress final zero(s), simply do this:
var discount = + ((price / listprice).toFixed(2));
Edited:
I've just discovered what seems to be a bug in Firefox 35.0.1, which means that the above may give NaN with some values.
I've changed my code to
var discount = Math.round(price / listprice * 100) / 100;
This gives a number with up to two decimal places. If you wanted three, you would multiply and divide by 1000, and so on.
The OP wants two decimal places always, but if toFixed() is broken in Firefox it needs fixing first.

IP2Int
code comes from this post, the other method is a fully (for my test cases) working fix of previous proposals in this question.
The code:
def IP2Int(ip):
o = map(int, ip.split('.'))
res = (16777216 * o[0]) + (65536 * o[1]) + (256 * o[2]) + o[3]
return res
def addressInNetwork(ip, net_n_bits):
ipaddr = IP2Int(ip)
net, bits = net_n_bits.split('/')
netaddr = IP2Int(net)
bits_num = int(bits)
netmask = ((1L << bits_num) - 1) << (32 - bits_num)
return ipaddr & netmask == netaddr & netmask
Hope useful,
There are multiple ways of doing that you can use either place
or grid
or even the pack
method.
Sample code:
from tkinter import *
root = Tk()
l = Label(root, text="hello" )
l.pack(padx=6, pady=4) # where padx and pady represent the x and y axis respectively
# well you can also use side=LEFT inside the pack method of the label widget.
To place a widget to on basis of columns and rows , use the grid method:
but = Button(root, text="hello" )
but.grid(row=0, column=1)
Revised Answer
If you're not calling this code from another program, an option is to skip PL/SQL and do it strictly in SQL using bind variables:
var myname varchar2(20);
exec :myname := 'Tom';
SELECT *
FROM Customers
WHERE Name = :myname;
In many tools (such as Toad and SQL Developer), omitting the var
and exec
statements will cause the program to prompt you for the value.
Original Answer
A big difference between T-SQL and PL/SQL is that Oracle doesn't let you implicitly return the result of a query. The result always has to be explicitly returned in some fashion. The simplest way is to use DBMS_OUTPUT
(roughly equivalent to print
) to output the variable:
DECLARE
myname varchar2(20);
BEGIN
myname := 'Tom';
dbms_output.print_line(myname);
END;
This isn't terribly helpful if you're trying to return a result set, however. In that case, you'll either want to return a collection or a refcursor. However, using either of those solutions would require wrapping your code in a function or procedure and running the function/procedure from something that's capable of consuming the results. A function that worked in this way might look something like this:
CREATE FUNCTION my_function (myname in varchar2)
my_refcursor out sys_refcursor
BEGIN
open my_refcursor for
SELECT *
FROM Customers
WHERE Name = myname;
return my_refcursor;
END my_function;

I would concatenate the old list and new list as streams and save the results to destination list. Works well in parallel, too.
I will use the example of accepted answer given by Stuart Marks:
List<String> destList = Arrays.asList("foo");
List<String> newList = Arrays.asList("0", "1", "2", "3", "4", "5");
destList = Stream.concat(destList.stream(), newList.stream()).parallel()
.collect(Collectors.toList());
System.out.println(destList);
//output: [foo, 0, 1, 2, 3, 4, 5]
Hope it helps.

I'd like to suggest another way to maintain python session through tmux on linux. you run tmux, attach your self to the session you opened (if not attached after opening it directly). execute python and do whatever you are doing on it. then detach from session. detaching from a tmux session does not close the session. the session remains open.
pros of this method: you can attach to this session from any other device (in case you can ssh your pc)
cons of this method: this method does not relinquish the resources used by the opened python session until you actually exist the python interpreter.
(\d+)\s+(\(.*?\))?\s?Z
Note the escaped parentheses, and the ?
(zero or once) quantifiers. Any of the groups you don't want to capture can be (?:
non-capture groups).
I agree about the spaces. \s
is a better option there. I also changed the quantifier to insure there are digits at the beginning. As far as newlines, that would depend on context: if the file is parsed line by line it won't be a problem. Another option is to anchor the start and end of the line (add a ^
at the front and a $
at the end).
As of nginx 1.8.0, the correct solution is
sudo nginx -t && sudo service nginx reload
Note that due to a bug, configtest
always returns a zero exit code even if the config file has an error.
I'd like to elaborate on Uliwitness answer, fixing his code for C++98 and using the Safe Bool idiom, for lack of the std::underlying_type<>
template and the explicit
keyword in C++ versions below C++11.
I also modified it so that the enum values can be sequential without any explicit assignment, so you can have
enum AnimalFlags_
{
HasClaws,
CanFly,
EatsFish,
Endangered
};
typedef FlagsEnum<AnimalFlags_> AnimalFlags;
seahawk.flags = AnimalFlags() | CanFly | EatsFish | Endangered;
You can then get the raw flags value with
seahawk.flags.value();
Here's the code.
template <typename EnumType, typename Underlying = int>
class FlagsEnum
{
typedef Underlying FlagsEnum::* RestrictedBool;
public:
FlagsEnum() : m_flags(Underlying()) {}
FlagsEnum(EnumType singleFlag):
m_flags(1 << singleFlag)
{}
FlagsEnum(const FlagsEnum& original):
m_flags(original.m_flags)
{}
FlagsEnum& operator |=(const FlagsEnum& f) {
m_flags |= f.m_flags;
return *this;
}
FlagsEnum& operator &=(const FlagsEnum& f) {
m_flags &= f.m_flags;
return *this;
}
friend FlagsEnum operator |(const FlagsEnum& f1, const FlagsEnum& f2) {
return FlagsEnum(f1) |= f2;
}
friend FlagsEnum operator &(const FlagsEnum& f1, const FlagsEnum& f2) {
return FlagsEnum(f1) &= f2;
}
FlagsEnum operator ~() const {
FlagsEnum result(*this);
result.m_flags = ~result.m_flags;
return result;
}
operator RestrictedBool() const {
return m_flags ? &FlagsEnum::m_flags : 0;
}
Underlying value() const {
return m_flags;
}
protected:
Underlying m_flags;
};
You didn't publish your code, and I suspect you do something wrong. it is possible to change the size by assigning width and height attributes using numbers:
canvasNode.width = 200; // in pixels
canvasNode.height = 100; // in pixels
At least it works for me. Make sure you don't assign strings (e.g., "2cm", "3in", or "2.5px"), and don't mess with styles.
Actually this is a publicly available knowledge — you can read all about it in the HTML canvas spec — it is very small and unusually informative. This is the whole DOM interface:
interface HTMLCanvasElement : HTMLElement {
attribute unsigned long width;
attribute unsigned long height;
DOMString toDataURL();
DOMString toDataURL(in DOMString type, [Variadic] in any args);
DOMObject getContext(in DOMString contextId);
};
As you can see it defines 2 attributes width
and height
, and both of them are unsigned long
.

$blog is an object, not an array, so you should access it like so:
$blog->id;
$blog->title;
$blog->content;
If you don't have idea about What could be the response from the API. Follow the steps to convert the responsebody response value into bytes and print in the String format You can get the entire response printed in the console.
Then you can convert string to JSONObject easily.
apiService.getFeeds(headerMap, map).enqueue(object : Callback, retrofit2.Callback<ResponseBody> {
override fun onFailure(call: Call<ResponseBody>?, t: Throwable?) {
}
override fun onResponse(call: Call<ResponseBody>?, response: Response<ResponseBody>?) {
val bytes = (response!!.body()!!.bytes())
Log.d("Retrofit Success : ", ""+ String(bytes))
}
})
If is ok for you to index the array you can do this:
<form>
<input type="text" class="form-control" placeholder="Titel" name="levels[0][level]">
<input type="text" class="form-control" placeholder="Titel" name="levels[0][build_time]">
<input type="text" class="form-control" placeholder="Titel" name="levels[1][level]">
<input type="text" class="form-control" placeholder="Titel" name="levels[1][build_time]">
<input type="text" class="form-control" placeholder="Titel" name="levels[2][level]">
<input type="text" class="form-control" placeholder="Titel" name="levels[2][build_time]">
</form>
... to achieve that:
[levels] => Array (
[0] => Array (
[level] => 1
[build_time] => 2
)
[1] => Array (
[level] => 234
[build_time] => 456
)
[2] => Array (
[level] => 111
[build_time] => 222
)
)
But if you remove one pair of inputs (dynamically, I suppose) from the middle of the form then you'll get holes in your array, unless you update the input names...
each JSF component renders itself out to HTML and has complete control over what HTML it produces. There are many tricks that can be used by JSF, and exactly which of those tricks will be used depends on the JSF implementation you are using.
For things like hlink you can include binding information in the url as query params or as part of the url itself or as matrx parameters. for examples.
http:..../somelink?componentId=123
would allow jsf to look in the component tree to see that link 123 was clicked. or it could e htp:..../jsf;LinkId=123
The easiest way to answer this question is to create a JSF page with only one link, then examine the html output it produces. That way you will know exactly how this happens using the version of JSF that you are using.
There can be one of the two cause for this error:
The public
keyword is used only when declaring a class method.
Since you're declaring a simple function and not a class you need to remove public
from your code.
The above solution for the JsonCreationConverter<T>
is all over the internet, but has a flaw that manifests itself in rare occasions. The new JsonReader created in the ReadJson method does not inherit any of the original reader's configuration values (Culture, DateParseHandling, DateTimeZoneHandling, FloatParseHandling, etc...). These values should be copied over before using the new JsonReader in serializer.Populate().
This is the best I could come up with to fix some of the problems with the above implementation, but I still think there are some things being overlooked:
Update I updated this to have a more explicit method that makes a copy of an existing reader. This just encapsulates the process of copying over individual JsonReader settings. Ideally this function would be maintained in the Newtonsoft library itself, but for now, you can use the following:
/// <summary>Creates a new reader for the specified jObject by copying the settings
/// from an existing reader.</summary>
/// <param name="reader">The reader whose settings should be copied.</param>
/// <param name="jToken">The jToken to create a new reader for.</param>
/// <returns>The new disposable reader.</returns>
public static JsonReader CopyReaderForObject(JsonReader reader, JToken jToken)
{
JsonReader jTokenReader = jToken.CreateReader();
jTokenReader.Culture = reader.Culture;
jTokenReader.DateFormatString = reader.DateFormatString;
jTokenReader.DateParseHandling = reader.DateParseHandling;
jTokenReader.DateTimeZoneHandling = reader.DateTimeZoneHandling;
jTokenReader.FloatParseHandling = reader.FloatParseHandling;
jTokenReader.MaxDepth = reader.MaxDepth;
jTokenReader.SupportMultipleContent = reader.SupportMultipleContent;
return jTokenReader;
}
This should be used as follows:
public override object ReadJson(JsonReader reader,
Type objectType,
object existingValue,
JsonSerializer serializer)
{
if (reader.TokenType == JsonToken.Null)
return null;
// Load JObject from stream
JObject jObject = JObject.Load(reader);
// Create target object based on JObject
T target = Create(objectType, jObject);
// Populate the object properties
using (JsonReader jObjectReader = CopyReaderForObject(reader, jObject))
{
serializer.Populate(jObjectReader, target);
}
return target;
}
Older solution follows:
/// <summary>Base Generic JSON Converter that can help quickly define converters for specific types by automatically
/// generating the CanConvert, ReadJson, and WriteJson methods, requiring the implementer only to define a strongly typed Create method.</summary>
public abstract class JsonCreationConverter<T> : JsonConverter
{
/// <summary>Create an instance of objectType, based properties in the JSON object</summary>
/// <param name="objectType">type of object expected</param>

public override bool CanConvert(Type objectType)
{
// FrameWork 4.5

}

/// <returns>Deserialized Object</returns>
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
if (reader.TokenType == JsonToken.Null)
return null;
// Load JObject from stream
JObject jObject = JObject.Load(reader);
// Create target object based on JObject
T target = Create(objectType, jObject);
//Create a new reader for this jObject, and set all properties to match the original reader.
JsonReader jObjectReader = jObject.CreateReader();
jObjectReader.Culture = reader.Culture;
jObjectReader.DateParseHandling = reader.DateParseHandling;
jObjectReader.DateTimeZoneHandling = reader.DateTimeZoneHandling;
jObjectReader.FloatParseHandling = reader.FloatParseHandling;
// Populate the object properties
serializer.Populate(jObjectReader, target);
return target;
}
/// <summary>Serializes to the specified type</summary>

I've found good example here Display-char-as-Hexadecimal-String-in-C++:
std::vector<char> randomBytes(n);
file.read(&randomBytes[0], n);
// Displaying bytes: method 1
// --------------------------
for (auto& el : randomBytes)
std::cout << std::setfill('0') << std::setw(2) << std::hex << (0xff & (unsigned int)el);
std::cout << '\n';
// Displaying bytes: method 2
// --------------------------
for (auto& el : randomBytes)
printf("%02hhx", el);
std::cout << '\n';
return 0;
Method 1 as shown above is probably the more C++ way:
Cast to an unsigned int
Usestd::hex
to represent the value as hexadecimal digits
Usestd::setw
andstd::setfill
from<iomanip>
to format
Note that you need to mask the cast int against0xff
to display the least significant byte:
(0xff & (unsigned int)el)
.Otherwise, if the highest bit is set the cast will result in the three most significant bytes being set to
ff
.

which will start all of the promises and while one is waiting it will go on with the others.
Unfortunately there's a simple answer to this question, and it's "No"
IF EXISTS....UPDATE
Don't do it. It forces two scans/seeks instead of one.
If update doesn't find a match on the WHERE clause, the cost of the update statement is just a seek/scan.
If it does find a match, and if you preface it w/ IF EXISTS, it has to find the same match twice. And in a concurrent environment, what was true for the EXISTS may not be true any longer for the UPDATE.
This is precisely why UPDATE/DELETE/INSERT statements allow a WHERE clause. Use it!
var test = "<div class='saved' >"+
"<div >test.test</div> <div class='remove'>[Remove]</div></div>";
You can add "\n" if you require line-break.
You have to realize that char[10]
is similar to a char*
(see comment by @DarkDust). You are in fact returning a pointer. Now the pointer points to a variable (str
) which is destroyed as soon as you exit the function, so the pointer points to... nothing!
Usually in C, you explicitly allocate memory in this case, which won't be destroyed when the function ends:
char* testfunc()
{
char* str = malloc(10 * sizeof(char));
return str;
}
Be aware though! The memory pointed at by str
is now never destroyed. If you don't take care of this, you get something that is known as a 'memory leak'. Be sure to free()
the memory after you are done with it:
foo = testfunc();
// Do something with your foo
free(foo);
URLs use forward slashes (/), not backward ones (as windows). Try:
serverURLS = "https://abc.my.domain.com:55555/update";
The reason why you get the error is that the URL class can't parse the host part of the string and therefore, host
is null
.

If you want to use different JDKs/JREs for each Java task, you can run update-alternatives to configure one java executable at a time; you can run
sudo update-alternatives --config java[Tab]
to see the Java commands that can be configured (java, javac, javah, javaws, etc). And then
sudo update-alternatives --config [javac|java|javadoc|etc.]
will associate that Java task/command to a particular JDK/JRE.
You may also need to set JAVA_HOME for some applications: from this answer you can use
export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")
for JREs, or
export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:jre/bin/java::")
for JDKs.
inside your onClickListener.onClick, put
getFragmentManager().beginTransaction().replace(R.id.container, new tasks()).commit();
In another word, in your mycontacts.class
public class mycontacts extends Fragment {
public mycontacts() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View v = super.getView(position, convertView, parent);
ImageView purple = (ImageView) v.findViewById(R.id.imageView1);
purple.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
getFragmentManager()
.beginTransaction()
.replace(R.id.container, new tasks())
.commit();
}
});
return view;
}
}
now, remember R.id.container
is the container (FrameLayout or other layouts) for the activity that calls the fragment
Or you can write your own filter using lodash.
app.filter('unique', function() {
return function (arr, field) {
return _.uniq(arr, function(a) { return a[field]; });
};
});
Use .text()
instead, and change your selector:
$(".ui-datepicker-prev .ui-icon.ui-icon-circle-triangle-w").text('<<');
you can use 'email' or 'emailx' command.
(1) $ vim /etc/mail.rc # or # vim /etc/nail.rc
set from = [email protected] #
set smtp = smtp.exmail.gmail.com #gmail's smtp server
set smtp-auth-user = [email protected] #sender's email address
set smtp-auth-password = xxxxxxx #get from gmail, not your email account passwd
set smtp-auth=login
(2) $ echo "Pls remember to remove unused ons topics!" | mail -s "waste topics" -a a.txt [email protected] #send to group user '[email protected]'
A endpoint is a URL for web service.And Endpoints also is a distributed API.
The Simple Object Access Protocol (SOAP) endpoint is a URL. It identifies the location on the built-in HTTP service where the web services listener listens for incoming requests.
file_get_contents('php://input') will not always work.
I have a request with in the headers "content-length=735" and "php://input" is empty string. So depends on how good/valid the HTTP request is.
{
"shell_cmd": "javac -Xlint \"${file}\"",

"variants": [

}
save this sublime build and run the program with ctrl + shift + B with run variant.Without run variant it will just create .class file but wont run it.
This build will read the input from input.txt and print the output in output.txt.
Note: both input.txt and output.txt must be present in the same working directory as your .java file.
try giving AppPool ID or Network Services whichever applicable access HKLM\SYSTEM\CurrentControlSet\services\eventlog\security also. I was getting the same error .. this worked for me. See the error is also saying that the inaccessible logs are Security Logs.
I also gave permission in eventlog\application .
I gave full access everywhere.
First you will need some GUI library with Python bindings and then (if you want) some program that will convert your python scripts into standalone executables.
Cross-platform GUI libraries with Python bindings (Windows, Linux, Mac)
Of course, there are many, but the most popular that I've seen in wild are:
Complete list is at http://wiki.python.org/moin/GuiProgramming

Use a cyclic scheduler. This gives you the ability to add regular maintenance times to check the correctness of critical data. The problem most often encountered is corruption of the stack. If your software is cyclical you can reinitialise the stack between cycles. Do not reuse the stacks for interrupt calls, setup a separate stack of each important interrupt call.
Similar to the Watchdog concept is deadline timers. Start a hardware timer before calling a function. If the function does not return before the deadline timer interrupts then reload the stack and try again. If it still fails after 3/5 tries you need reload from ROM.
Split your software into parts and isolate these parts to use separate memory areas and execution times (Especially in a control environment). Example: signal acquisition, prepossessing data, main algorithm and result implementation/transmission. This means a failure in one part will not cause failures through the rest of the program. So while we are repairing the signal acquisition the rest of tasks continues on stale data.
Everything needs CRCs. If you execute out of RAM even your .text needs a CRC. Check the CRCs regularly if you using a cyclical scheduler. Some compilers (not GCC) can generate CRCs for each section and some processors have dedicated hardware to do CRC calculations, but I guess that would fall out side of the scope of your question. Checking CRCs also prompts the ECC controller on the memory to repair single bit errors before it becomes a problem.
Here is a talk about the differences between web sockets and server sent events. Since Java EE 7 a WebSocket API is already part of the specification and it seems that server sent events will be released in the next version of the enterprise edition.
SHOW SESSION VARIABLES LIKE "wait_timeout"; -- 28800
SHOW GLOBAL VARIABLES LIKE "wait_timeout"; -- 28800
At first, wait_timeout = 28800 which is the default value. To change the session value, you need to set the global variable because the session variable is read-only.
SET @@GLOBAL.wait_timeout=300
After you set the global variable, the session variable automatically grabs the value.
SHOW SESSION VARIABLES LIKE "wait_timeout"; -- 300
SHOW GLOBAL VARIABLES LIKE "wait_timeout"; -- 300
Next time when the server restarts, the session variables will be set to the default value i.e. 28800.
P.S. I m using MySQL 5.6.16
You just can put your query as a subquery:
SELECT avg(count)
FROM
(
SELECT COUNT (*) AS Count
FROM Table T
WHERE T.Update_time =
(SELECT MAX (B.Update_time )
FROM Table B
WHERE (B.Id = T.Id))
GROUP BY T.Grouping
) as counts
Edit: I think this should be the same:
SELECT count(*) / count(distinct T.Grouping)
FROM Table T
WHERE T.Update_time =
(SELECT MAX (B.Update_time)
FROM Table B
WHERE (B.Id = T.Id))
for i in $(seq 1 254); do ping -c1 192.168.11.$i; done
To get it on init
public innerWidth: any;
ngOnInit() {
this.innerWidth = window.innerWidth;
}
If you wanna keep it updated on resize:
@HostListener('window:resize', ['$event'])
onResize(event) {
this.innerWidth = window.innerWidth;
}
Pretty sure that this exception is thrown when the Excel file is either password protected or the file itself is corrupted. If you just want to read a .xlsx file, try my code below. It's a lot more shorter and easier to read.
import org.apache.poi.ss.usermodel.WorkbookFactory;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.Sheet;
//.....
static final String excelLoc = "C:/Documents and Settings/Users/Desktop/testing.xlsx";
public static void ReadExcel() {
InputStream inputStream = null;
try {
inputStream = new FileInputStream(new File(excelLoc));
Workbook wb = WorkbookFactory.create(inputStream);
int numberOfSheet = wb.getNumberOfSheets();
for (int i = 0; i < numberOfSheet; i++) {
Sheet sheet = wb.getSheetAt(i);
//.... Customize your code here
// To get sheet name, try -> sheet.getSheetName()
}
} catch {}
}
Issue related to git commands on Windows operating system:
$ git add --all
warning: LF will be replaced by CRLF in ...
The file will have its original line endings in your working directory.
Resolution:
$ git config --global core.autocrlf false
$ git add --all
No any warning messages come up.
You can also use the Ellipsis when specifying expected doctest output:
class MyClass(object):
"""Example of a doctest Ellipsis
>>> thing = MyClass()
>>> # Match <class '__main__.MyClass'> and <class '%(module).MyClass'>
>>> type(thing) # doctest:+ELLIPSIS
<class '....MyClass'>
"""
pass
It depends, but I would say it is better to keep everything in one table for that sake of simplicity.
100,000 rows a day is not really that much of an enormous amount. (Depending on your server hardware). I have personally seen MSSQL handle up to 100M rows in a single table without any problems. As long as your keep your indexes in order it should be all good. The key is to have heaps of memory so that indexes don't have to be swapped out to disk.
On the other hand, it depends on how you are using the data, if you need to make lots of query's, and its unlikely data will be needed that spans multiple days (so you won't need to join the tables) it will be faster to separate out it out into multiple tables. This is often used in applications such as industrial process control where you might be reading the value on say 50,000 instruments every 10 seconds. In this case speed is extremely important, but simplicity is not.
1: Go to the gradle enable multiDexEnabled and add the multidex library in the dependencies.
android {
...
defaultConfig {
multiDexEnabled true
...
}
}
dependencies {
// add dependency
implementation 'com.android.support:multidex:1.0.1'
}
2: Go to the Manifest file and write android:name=".MyApplication" (Class name(MyApplication) is optional you can write whatever you want ).
<application
android:name=".MyApplication"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
.
.
.
.
.
</application>
3: As you wrote android:name=".MyApplication" Inside Application at Manifest file. it will give you an error because you didn't create MyApplication class. Create MyApplication Class extend it by "application" class or Simply click on.MyApplication, a small red balloon appear on the left side of a syntax click on it, you will see (create MyApplication class) in the menu, click on it and Include below Method Inside that class.
public class MyApplication extends Application {
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}

If you use MAMP, you might have to set the socket: unix_socket: /Applications/MAMP/tmp/mysql/mysql.sock
There are three ways to do it,
a) using a service
b) Exploiting depending parent/child relation between controller scopes.
c) In Angular 2.0 "As" keyword will be pass the data from one controller to another.

You are seeing a Git safety feature. Git refuses to update the remote branch with your branch, because your branch's head commit is not a direct descendent of the current head commit of the branch that you are pushing to.
If this were not the case, then two people pushing to the same repository at about the same time would not know that there was a new commit coming in at the same time and whoever pushed last would lose the work of the previous pusher without either of them realising this.
If you know that you are the only person pushing and you want to push an amended commit or push a commit that winds back the branch, you can 'force' Git to update the remote branch by using the -f
switch.
git push -f origin master
Even this may not work as Git allows remote repositories to refuse non-fastforward pushes at the far end by using the configuration variable receive.denynonfastforwards
. If this is the case the rejection reason will look like this (note the 'remote rejected' part):
! [remote rejected] master -> master (non-fast forward)
To get around this, you either need to change the remote repository's configuration or as a dirty hack you can delete and recreate the branch thus:
git push origin :master
git push origin master
In general the last parameter to git push
uses the format <local_ref>:<remote_ref>
, where local_ref
is the name of the branch on the local repository and remote_ref
is the name of the branch on the remote repository. This command pair uses two shorthands. :master
has a null local_ref which means push a null branch to the remote side master
, i.e. delete the remote branch. A branch name with no :
means push the local branch with the given name to the remote branch with the same name. master
in this situation is short for master:master
.
use below code it helps you....
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 4;
options.inPurgeable = true;
Bitmap bm = BitmapFactory.decodeFile("your path of image",options);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG,40,baos);
// bitmap object
byteImage_photo = baos.toByteArray();
//generate base64 string of image
String encodedImage =Base64.encodeToString(byteImage_photo,Base64.DEFAULT);
//send this encoded string to server
auto cmp = [](int a, int b) { return ... };
std::set<int, decltype(cmp)> s;
We use lambda function as comparator. As usual, comparator should return boolean value, indicating whether the element passed as first argument is considered to go before the second in the specific strict weak ordering it defines.
auto cmp = [](int a, int b) { return ... };
std::set<int, decltype(cmp)> s(cmp);
Before C++20 we need to pass lambda as argument to set constructor
Make comparator as usual boolean function
bool cmp(int a, int b) {
return ...;
}
Then use it, either this way:
std::set<int, decltype(cmp)*> s(cmp);
or this way:
std::set<int, decltype(&cmp)> s(&cmp);
()
operatorstruct cmp {
bool operator() (int a, int b) const {
return ...
}
};
// ...
// later
std::set<int, cmp> s;
Take boolean function
bool cmp(int a, int b) {
return ...;
}
And make struct from it using std::integral_constant
#include <type_traits>
using Cmp = std::integral_constant<decltype(&cmp), &cmp>;
Finally, use the struct as comparator
std::set<X, Cmp> set;
You could simply use:
select {
border: none;
outline: none;
scroll-behavior: smooth;
}
As the drop down list border is non editable you can not do anything with that but surely this will fix your initial outlook.
This one line of code saved me:
textField.Layer.SublayerTransform = CATransform3D.MakeTranslation(5, 0, 0);
textField.layer.sublayerTransform = CATransform3DMakeTranslation(5, 0, 0);
A true restart is not possible AFAIK. (Please correct me if I'm wrong!).
However, if you want to set it to 0, you can just delete and recreate it.
If you want to set it to a specific value, you can set the INCREMENT to a negative value and get the next value.
That is, if your sequence is at 500, you can set it to 100 via
ALTER SEQUENCE serial INCREMENT BY -400;
SELECT serial.NEXTVAL FROM dual;
ALTER SEQUENCE serial INCREMENT BY 1;
Easy approach:
CREATE TABLE T
(
C [nvarchar](100) NOT NULL UNIQUE,
);
SET XACT_ABORT ON -- Turns on rollback if T-SQL statement raises a run-time error.
SELECT * FROM T; -- Check before.
BEGIN TRAN
INSERT INTO T VALUES ('A');
INSERT INTO T VALUES ('B');
INSERT INTO T VALUES ('B');
INSERT INTO T VALUES ('C');
COMMIT TRAN
SELECT * FROM T; -- Check after.
DELETE T;
Surely have a mutex-wrapped variable initialised to false
, that the thread sets to true
as the last thing it does before exiting. Is that atomic enough for your needs?

Here are the rules for how these functions work:
stringValue.CompareTo(otherStringValue)
null
comes before a stringCultureInfo.CurrentCulture.CompareInfo.Compare
, which means it will use a culture-dependent comparison. This might mean that ß
will compare equal to SS
in Germany, or similarstringValue.Equals(otherStringValue)
null
is not considered equal to anythingStringComparison
option, it will use what looks like a direct ordinal equality check, i.e. ß
is not the same as SS
, in any language or culturestringValue == otherStringValue
stringValue.Equals()
.==
operator calls the static Equals(string a, string b)
method (which in turn goes to an internal EqualsHelper
to do the comparison..Equals()
on a null
string gets null
reference exception, while on ==
does not.Object.ReferenceEquals(stringValue, otherStringValue)
Just checks that references are the same, i.e. it isn't just two strings with the same contents, you're comparing a string object with itself.
Note that with the options above that use method calls, there are overloads with more options to specify how to compare.
My advice if you just want to check for equality is to make up your mind whether you want to use a culture-dependent comparison or not, and then use .CompareTo
or .Equals
, depending on the choice.
It seems that you are looking to parse commandline arguments into your bash script. I have searched for this recently myself. I came across the following which I think will assist you in parsing the arguments:
http://rsalveti.wordpress.com/2007/04/03/bash-parsing-arguments-with-getopts/
I added the snippet below as a tl;dr
#using : after a switch variable means it requires some input (ie, t: requires something after t to validate while h requires nothing.
while getopts “ht:r:p:v” OPTION
do
case $OPTION in
h)
usage
exit 1
;;
t)
TEST=$OPTARG
;;
r)
SERVER=$OPTARG
;;
p)
PASSWD=$OPTARG
;;
v)
VERBOSE=1
;;
?)
usage
exit
;;
esac
done
if [[ -z $TEST ]] || [[ -z $SERVER ]] || [[ -z $PASSWD ]]
then
usage
exit 1
fi
./script.sh -t test -r server -p password -v
You can use for loop
int[] random_numbers = {10, 30, 44, 21, 51, 21, 61, 24, 14}
int array_length = random_numbers.Length;
for (int i = 0; i < array_length; i++){
if(i == array_length - 1){
Console.Write($"{random_numbers[i]}\n");
} else{
Console.Write($"{random_numbers[i]}, ");
}
}
Here u Go
f = open('test.txt','rb+')
ch=f.read(1)
ch=str(ch,'utf-8')
print(ch)
You need to log in with the correct username and password. Does the user root have permission to access the database? or did you create a specific user to do this?
The other issue might be that you are not using a password when trying to log in.
The problem is not with extract
, which can certainly handle 'military time'. It looks like you have a default timestamp format which has HH
instead of HH24
; or at least that's the only way I can see to recreate this:
SQL> select value from nls_session_parameters
2 where parameter = 'NLS_TIMESTAMP_FORMAT';
VALUE
--------------------------------------------------------------------------------
DD-MON-RR HH24.MI.SSXFF
SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
2 as timestamp)) from dual;
EXTRACT(HOURFROMCAST(TO_CHAR(SYSDATE,'DD-MON-YYYYHH24:MI:SS')ASTIMESTAMP))
--------------------------------------------------------------------------
15
alter session set nls_timestamp_format = 'DD-MON-YYYY HH:MI:SS';
Session altered.
SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
2 as timestamp)) from dual;
select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS') as timestamp)) from dual
*
ERROR at line 1:
ORA-01849: hour must be between 1 and 12
So the simple 'fix' is to set the format to something that does recognise 24-hours:
SQL> alter session set nls_timestamp_format = 'DD-MON-YYYY HH24:MI:SS';
Session altered.
SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
2 as timestamp)) from dual;
EXTRACT(HOURFROMCAST(TO_CHAR(SYSDATE,'DD-MON-YYYYHH24:MI:SS')ASTIMESTAMP))
--------------------------------------------------------------------------
15
Although you don't need the to_char
at all:
SQL> select extract(hour from cast(sysdate as timestamp)) from dual;
EXTRACT(HOURFROMCAST(SYSDATEASTIMESTAMP))
-----------------------------------------
15
The simple answer is, "You don't." At the point where you need something to be of fixed length, you're either stuck on old habits or writing for a very specific problem with its own unique set of constraints.

Java caches the primitive values from -128 to 127. When we compare two Long objects java internally type cast it to primitive value and compare it. But above 127 the Long object will not get type caste. Java caches the output by .valueOf() method.
This caching works for Byte, Short, Long from -128 to 127. For Integer caching works From -128 to java.lang.Integer.IntegerCache.high or 127, whichever is bigger.(We can set top level value upto which Integer values should get cached by using java.lang.Integer.IntegerCache.high).
For example:
If we set java.lang.Integer.IntegerCache.high=500;
then values from -128 to 500 will get cached and
Integer a=498;
Integer b=499;
System.out.println(a==b)
Output will be "true".
Float and Double objects never gets cached.
Character will get cache from 0 to 127
You are comparing two objects. so == operator will check equality of object references. There are following ways to do it.
1) type cast both objects into primitive values and compare
(long)val3 == (long)val4
2) read value of object and compare
val3.longValue() == val4.longValue()
3) Use equals() method on object comparison.
val3.equals(val4);
Agree with Jewes, XmlReader is the better way to go, especially if working with a larger XML document or processing multiple in a loop - no need to parse the entire document if you only need the document root.
Here's a simplified version, using XmlReader and MoveToContent().
http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.movetocontent.aspx
using (XmlReader xmlReader = XmlReader.Create(p_fileName))
{
if (xmlReader.MoveToContent() == XmlNodeType.Element)
rootNodeName = xmlReader.Name;
}
As the answer by @plaul mentions TouchableOpacity
, here is an example of how you can use that;
<TouchableOpacity
style={someStyles}
onPress={doSomething}
>
<Text>Press Here</Text>
</TouchableOpacity>
maybe you could use AsyncStorage setItem and getItem...and store the data as string, then use the json parser for convert it again to json...
You might need to change your object to an array first. I dont know what export
does, but I assume its expecting an array.
You can either use
Or if its a simple object, you can just typecast it.
$arr = (array) $Object;
You should use Merge: For example:
MERGE INTO employees e
USING (SELECT * FROM hr_records WHERE start_date > ADD_MONTHS(SYSDATE, -1)) h
ON (e.id = h.emp_id)
WHEN MATCHED THEN
UPDATE SET e.address = h.address
WHEN NOT MATCHED THEN
INSERT (id, address)
VALUES (h.emp_id, h.address);
or
MERGE INTO employees e
USING hr_records h
ON (e.id = h.emp_id)
WHEN MATCHED THEN
UPDATE SET e.address = h.address
WHEN NOT MATCHED THEN
INSERT (id, address)
VALUES (h.emp_id, h.address);
try changing in the gradle file the targetSdkVersion to 8
targetSdkVersion 8
You may be able to hide a heading if you can add the following CSS:
<style>
th {
display: none;
}
</style>
This is a bit heavy-handed and doesn’t distinguish between tables, but it may do for a simple task.
You won't be able to convert it directly to long because of the decimal point i think you should convert it into decimal and then convert it into long something like this:
String strValue[i] = "1100.25";
long l1 = Convert.ToInt64(Convert.ToDecimal(strValue));
hope this helps!
A CGI script is a console/shell program. In Windows, when you use a "Command Prompt" window, you execute console programs. When a web server executes a CGI script it provides input to the console/shell program using environment variables or "standard input". Standard input is like typing data into a console/shell program; in the case of a CGI script, the web server does the typing. The CGI script writes data out to "standard output" and that output is sent to the client (the web browser) as a HTML page. Standard output is like the output you see in a console/shell program except the web server reads it and sends it out.
A CGI script can be executed from a browser. The URI typically includes a query string that is provided to the CGI script. If the method is "get" then the query string is provided to the CGI Script in an environment variable called QUERY_STRING. If the method is "post" then the query string is provided to the CGI Script using standard input (the CGI Script reads the query string from standard input).
An early use of CGI scripts was to process forms. In the beginning of HTML, HTML forms typically had an "action" attribute and a button designated as the "submit" button. When the submit button is pushed the URI specified in the "action" attribute would be sent to the server with the data from the form sent as a query string. If the "action" specifies a CGI script then the CGI script would be executed and it then produces a HTML page.
RFC 3875 "The Common Gateway Interface (CGI)" partially defines CGI using C, as in saying that environment variables "are accessed by the C library routine getenv() or variable environ".
If you are developing a CGI script using C/C++ and use Microsoft Visual Studio to do that then you would develop a console program.
Is this endpoint taking too many time?
Maybe you are using flask without asynchronous support, so every request will block the call. To create async support without make difficult, add the gevent
worker.
With gevent, a new call will spawn a new thread, and you app will be able to receive more requests
pip install gevent
gunicon .... --worker-class gevent
Since I cant comment yet im gonna post as an answer the link.. I have found a simple, well organized tutorial on recyclerview http://www.androiddeft.com/2017/10/01/recyclerview-android/
Apart from that when you are going to add a recycler view into you activity what you want to do is as below and how you should do this has been described on the link
I would suggest using numpy's sort, as it is anyway what pandas is doing in background:
import numpy as np
np.sort(df.A.unique())
But doing all in pandas is valid as well.
This code is better than ours, you only need to add 2 libs: javax.servelet.jar and org.mortbay.jetty.jar.
Class Jetty:
package jetty;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.mortbay.http.SocketListener;
import org.mortbay.jetty.Server;
import org.mortbay.jetty.servlet.ServletHttpContext;
public class Jetty {
public static void main(String[] args) {
try {
Server server = new Server();
SocketListener listener = new SocketListener();
System.out.println("Max Thread :" + listener.getMaxThreads() + " Min Thread :" + listener.getMinThreads());
listener.setHost("localhost");
listener.setPort(8070);
listener.setMinThreads(5);
listener.setMaxThreads(250);
server.addListener(listener);
ServletHttpContext context = (ServletHttpContext) server.getContext("/");
context.addServlet("/MO", "jetty.HelloWorldServlet");
server.start();
server.join();
/*//We will create our server running at http://localhost:8070
Server server = new Server();
server.addListener(":8070");
//We will deploy our servlet to the server at the path '/'
//it will be available at http://localhost:8070
ServletHttpContext context = (ServletHttpContext) server.getContext("/");
context.addServlet("/MO", "jetty.HelloWorldServlet");
server.start();
*/
} catch (Exception ex) {
Logger.getLogger(Jetty.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
Servlet class:
package jetty;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class HelloWorldServlet extends HttpServlet
{
@Override
protected void doGet(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws ServletException, IOException
{
String appid = httpServletRequest.getParameter("appid");
String conta = httpServletRequest.getParameter("conta");
System.out.println("Appid : "+appid);
System.out.println("Conta : "+conta);
httpServletResponse.setContentType("text/plain");
PrintWriter out = httpServletResponse.getWriter();
out.println("Hello World!");
out.close();
}
}
There is an indirect way:
myModel:where('anyColumnName', 'like', '%%')->delete();
Example:
User:where('id', 'like' '%%')->delete();

Alex's answer shows you a solution for standard normal distribution (mean = 0, standard deviation = 1). If you have normal distribution with mean
and std
(which is sqr(var)
) and you want to calculate:
from scipy.stats import norm
# cdf(x < val)
print norm.cdf(val, m, s)
# cdf(x > val)
print 1 - norm.cdf(val, m, s)
# cdf(v1 < x < v2)
print norm.cdf(v2, m, s) - norm.cdf(v1, m, s)
Read more about cdf here and scipy implementation of normal distribution with many formulas here.
Try this function....it works...
$(function() {
var myOptions = {
zoom: 10,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"),myOptions);
var latlng_pos=[];
var j=0;
$(".property_item").each(function(){
latlng_pos[j]=new google.maps.LatLng($(this).find(".latitude").val(),$(this).find(".longitude").val());
j++;
var marker = new google.maps.Marker({
position: new google.maps.LatLng($(this).find(".latitude").val(),$(this).find(".longitude").val()),
// position: new google.maps.LatLng(-35.397, 150.640),
map: map
});
}
);
// map: an instance of google.maps.Map object
// latlng: an array of google.maps.LatLng objects
var latlngbounds = new google.maps.LatLngBounds( );
for ( var i = 0; i < latlng_pos.length; i++ ) {
latlngbounds.extend( latlng_pos[ i ] );
}
map.fitBounds( latlngbounds );
});
On groupby
object, the agg
function can take a list to apply several aggregation methods at once. This should give you the result you need:
df[['col1', 'col2', 'col3', 'col4']].groupby(['col1', 'col2']).agg(['mean', 'count'])
?max
shows you that there is an extra parameter na.rm
that you can set to TRUE
.
Apart from that, if you really want to remove the NA
s, just use something like:
myvec[!is.na(myvec)]

Short Answer : String is immutable – whereas StringBuilder is mutable.
What does that mean ? Wiki says : In object-oriented, an immutable object is an object whose state cannot be modified after it is created. This is in contrast to a mutable object, which can be modified after it is created.
From the StringBuilder Class documentation:
The String object is immutable. Every time you use one of the methods in the System.String class, you create a new string object in memory, which requires a new allocation of space for that new object.
In situations where you need to perform repeated modifications to a string, the overhead associated with creating a new String object can be costly.
The System.Text.StringBuilder class can be used when you want to modify a string without creating a new object. For example, using the StringBuilder class can boost performance when concatenating many strings together in a loop.
If you do not really care about rounding, just added a toFixed(x) and then removing trailing 0es and the dot if necessary. It is not a fast solution.
function format(value, decimals) {
if (value) {
value = value.toFixed(decimals);
} else {
value = "0";
}
if (value.indexOf(".") < 0) { value += "."; }
var dotIdx = value.indexOf(".");
while (value.length - dotIdx <= decimals) { value += "0"; } // add 0's
return value;
}
Example for String Methods
Given a list of filenames, we want to rename all the files with extension hpp to the extension h. To do this, we would like to generate a new list called newfilenames, consisting of the new filenames. Fill in the blanks in the code using any of the methods you’ve learned thus far, like a for loop or a list comprehension.
filenames = ["program.c", "stdio.hpp", "sample.hpp", "a.out", "math.hpp", "hpp.out"]
# Generate newfilenames as a list containing the new filenames
# using as many lines of code as your chosen method requires.
newfilenames = []
for i in filenames:
if i.endswith(".hpp"):
x = i.replace("hpp", "h")
newfilenames.append(x)
else:
newfilenames.append(i)
print(newfilenames)
# Should be ["program.c", "stdio.h", "sample.h", "a.out", "math.h", "hpp.out"]
We had a server redirect in Express:
app.get('*', function(req, res){
res.render('index');
});
and we were still getting page-refresh issues, even after we added the <base href="/" />
.
Solution: make sure you're using real links in you page to navigate; don't type in the route in the URL or you'll get a page-refresh. (silly mistake, I know)
:-P
Here's another variation that doesn't use Array
.
let range = (n, l=[], delta=1) => {
if (n < 0) {
return l
}
else {
l.unshift(n)
return range(n - delta, l)
}
}
