The IN clause describes a set of values, and sets do not have order.
Your solution with a join and then ordering on the display_order
column is the most nearly correct solution; anything else is probably a DBMS-specific hack (or is doing some stuff with the OLAP functions in standard SQL). Certainly, the join is the most nearly portable solution (though generating the data with the display_order
values may be problematic). Note that you may need to select the ordering columns; that used to be a requirement in standard SQL, though I believe it was relaxed as a rule a while ago (maybe as long ago as SQL-92).
Probably, you need to insert schema identifier here:
in.addValue("po_system_users", null, OracleTypes.ARRAY, "your_schema.T_SYSTEM_USER_TAB");
Simply git checkout have 2 uses
git checkout <existing_local_branch_name>
git checkout -b <new_feature_branch_name>
will create a new branch with the contents of master and switch to newly created branchYou can find more options at the official site
First, you need to convert your string to NSDate with its format. Then, you change the dateFormatter
to your simple format and convert it back to a String.
Swift 3
let dateString = "Thu, 22 Oct 2015 07:45:17 +0000"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "EEE, dd MMM yyyy hh:mm:ss +zzzz"
dateFormatter.locale = Locale.init(identifier: "en_GB")
let dateObj = dateFormatter.date(from: dateString)
dateFormatter.dateFormat = "MM-dd-yyyy"
print("Dateobj: \(dateFormatter.string(from: dateObj!))")
The printed result is: Dateobj: 10-22-2015
input { float: right; clear: both; }
CPU Virtualization is enabled by default on all MacBooks with compatible CPUs (i7 is compatible). You can try to reset PRAM if you think it was disabled somehow, but I doubt it.
I think the issue might be in the old version of OS. If your MacBook is i7, then you better upgrade OS to something newer.
You can hide the modal and popup the window to review the carts in validateShipping() function itself.
function validateShipping(){
...
...
$('#product-options').modal('hide');
//pop the window to select items
}
How about doing it with Pillow:
from PIL import Image
img = Image.open('image.png').convert('LA')
img.save('greyscale.png')
Using matplotlib and the formula
Y' = 0.2989 R + 0.5870 G + 0.1140 B
you could do:
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.image as mpimg
def rgb2gray(rgb):
return np.dot(rgb[...,:3], [0.2989, 0.5870, 0.1140])
img = mpimg.imread('image.png')
gray = rgb2gray(img)
plt.imshow(gray, cmap=plt.get_cmap('gray'), vmin=0, vmax=1)
plt.show()
If you need async: false
in your ajax, you should use success
instead of .done
. Else you better to use .done
.
This is from jQuery official site:
As of jQuery 1.8, the use of async: false with jqXHR ($.Deferred) is deprecated; you must use the success/error/complete callback options instead of the corresponding methods of the jqXHR object such as jqXHR.done().
It's actually easy and straight forward.
just navigate to your .m2 folder.
.m2/repository/org/apache/maven
inside this maven folder, you will see a folder called Archetypes... delete this folder and the problem is solved.
but if you don't feel like deleting the whole folder, you can navigate into the archetype folder and delete all the archetype you want there. The reason why it keeps failing is because, the archetype you are trying to create is trying to tell you that she already exists in that folder, hence move away...
summarily, deleting the archetype folder in the .m2 folder is the easiest solution.
In my case, it was due to an IP address that Apache is listening to. Previously I have set it to 192.168.10.6 and recently Apache service is not running. I noticed that due to My laptop wifi changed recently and new IP is different. After fixing the wifi IP to laptop previous IP, Apache service is running again without any error.
Also if you don't want to change wifi IP then remove/comment that hardcode IP in httpd.conf file to resolve conflict.
I concur with the Dragon Book reference; IMO, it is the definitive guide to compiler construction. Get ready for some hardcore theory, though.
If you want a book that is lighter on theory, Game Scripting Mastery might be a better book for you. If you are a total newbie at compiler theory, it provides a gentler introduction. It doesn't cover more practical parsing methods (opting for non-predictive recursive descent without discussing LL or LR parsing), and as I recall, it doesn't even discuss any sort of optimization theory. Plus, instead of compiling to machine code, it compiles to a bytecode that is supposed to run on a VM that you also write.
It's still a decent read, particularly if you can pick it up for cheap on Amazon. If you only want an easy introduction into compilers, Game Scripting Mastery is not a bad way to go. If you want to go hardcore up front, then you should settle for nothing less than the Dragon Book.
If you want to get a list of all tablespaces used in the current database instance, you can use the DBA_TABLESPACES view as shown in the following SQL script example:

2 FROM USER_TABLESPACES;

This is probably simpler than you're thinking:
int w = WIDTH_PX, h = HEIGHT_PX;
Bitmap.Config conf = Bitmap.Config.ARGB_8888; // see other conf types
Bitmap bmp = Bitmap.createBitmap(w, h, conf); // this creates a MUTABLE bitmap
Canvas canvas = new Canvas(bmp);
// ready to draw on that bitmap through that canvas
Here's a series of tutorials I've found on the topic: Drawing with Canvas Series
for another answer about this type of question this is my another answer for getting count of product base on product name distinct like this sample below:
select * FROM Product
SELECT DISTINCT(Product_Name),
(SELECT COUNT(Product_Name)
from Product WHERE Product_Name = Prod.Product_Name)
as `Product_Count`
from Product as Prod
Record Count: 4; Execution Time: 2ms
You can do it in code by calling the following functions.
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
or
error_reporting(E_ALL ^ E_DEPRECATED);

Using pathlib, you have the following solution :
Let's say we want to check if son
is a descendant of parent
, and both are Path
objects.
We can get a list of the parts in the path with list(parent.parts)
.
Then, we just check that the begining of the son is equal to the list of segments of the parent.
>>> lparent = list(parent.parts)
>>> lson = list(son.parts)
>>> if lson[:len(lparent)] == lparent:
>>> ... #parent is a parent of son :)
If you want to get the remaining part, you can just do
>>> ''.join(lson[len(lparent):])
It's a string, but you can of course use it as a constructor of an other Path object.
I ended up setting my own drop shadow for the toolbar, thought it might helpful for anyone looking for it:

Most times, you won't need to "convert"; VBA will do safe implicit type conversion for you, without the use of converters like CStr
.
The below code works without any issues, because the variable is of Type String, and implicit type conversion is done for you automatically!
Dim myVal As String
Dim myNum As Integer
myVal = "My number is: "
myVal = myVal & myNum
Result:
"My number is: 0"
You don't even have to get that fancy, this works too:
Dim myString as String
myString = 77
"77"
The only time you WILL need to convert is when the variable Type is ambiguous (e.g., Type Variant, or a Cell's Value
(which is Variant)).
Even then, you won't have to use CStr
function if you're compounding with another String variable or constant. Like this:
Sheet1.Range("A1").Value = "My favorite number is " & 7
"My favorite number is 7"
So, really, the only rare case is when you really want to store an integer value, into a variant or Cell value, when not also compounding with another string (which is a pretty rare side case, I might add):
Dim i as Integer
i = 7
Sheet1.Range("A1").Value = i
7
Dim i as Integer
i = 7
Sheet1.Range("A1").Value = CStr(i)
"7"
Maybe you were trying to do this?
#include <stdio.h>
int func(int * B){
/* B + OFFSET = 5 () You are pointing to the same region as B[OFFSET] */
*(B + 2) = 5;
}
int main(void) {
int B[10];
func(B);
/* Let's say you edited only 2 and you want to show it. */
printf("b[0] = %d\n\n", B[2]);
return 0;
}

Online converter, nice way and time saver ;)
Code:
function textToBin(text) {
var length = text.length,
output = [];
for (var i = 0;i < length; i++) {
var bin = text[i].charCodeAt().toString(2);
output.push(Array(8-bin.length+1).join("0") + bin);
}
return output.join(" ");
}
textToBin("!a") => "00100001 01100001"
Another way
function textToBin(text) {
return (
Array
.from(text)
.reduce((acc, char) => acc.concat(char.charCodeAt().toString(2)), [])
.map(bin => '0'.repeat(8 - bin.length) + bin )
.join(' ')
);
}

set @d=getdate();
set @dow=((datepart(dw,@d) + @@DATEFIRST-2) % 7+1);
use this script to calculate end of div
$('#bottom').offset().top +$('#bottom').height()
you must use the following properties for a button
element to make it transparent.
button {
background: transparent;
border: none !important;
font-size:0;
}
button {
background: transparent;
border: none !important;
}?
and use absolute position
to position the element.
you have the button element under a div. Use position
: relative on div and position
: absolute on the button to position it within the div.
here is a working JSFiddle
here is an updated JSFiddle that displays only text from the button.
Yes you can...
PDFs have Javascript support. I needed to have auto print capabilities when a PHP-generated PDF was created and I was able to use FPDF to get it to work:
I know that this question was answered a while ago and i appologize for the intrusion. However,I was working on a way of doing this in python as well and i just thought that i would share the way that i did it in is as follows,
word = 'aibohphobia'
word_rev = reversed(word)
def is_palindrome(word):
if list(word) == list(word_rev):
print'True, it is a palindrome'
else:
print'False, this is''t a plindrome'
is_palindrome(word)
Update Oct 2020: Checkout the Lifecycle extensions based solutions on this thread. The approach seems to be working, it's more elegant and modern.
The neatest and not deprecated way that I've found so far to do this, as follows:
@Override
public boolean foregrounded() {
ActivityManager.RunningAppProcessInfo appProcessInfo = new ActivityManager.RunningAppProcessInfo();
ActivityManager.getMyMemoryState(appProcessInfo);
return (appProcessInfo.importance == IMPORTANCE_FOREGROUND || appProcessInfo.importance == IMPORTANCE_VISIBLE)
}
It only works with SDK 16+.
EDIT:
I removed the following code from the solution:
KeyguardManager km = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
// App is foreground, but screen is locked, so show notification
return km.inKeyguardRestrictedInputMode();
since that makes not getting the notifications if the screen locked. I had a look to the framework and the purpose of this is not entirely clear. I'd remove it. Checking the process info state would be enough :-)
You can use fmt.Sprintf or strconv.FormatFloat
For example
package main
import (
"fmt"
)
func main() {
val := 14.7
s := fmt.Sprintf("%f", val)
fmt.Println(s)
}
The default logging level is warning. Since you haven't changed the level, the root logger's level is still warning. That means that it will ignore any logging with a level that is lower than warning, including debug loggings.
This is explained in the tutorial:
import logging
logging.warning('Watch out!') # will print a message to the console
logging.info('I told you so') # will not print anything
The 'info' line doesn't print anything, because the level is higher than info.
To change the level, just set it in the root logger:
'root':{'handlers':('console', 'file'), 'level':'DEBUG'}
In other words, it's not enough to define a handler with level=DEBUG, the actual logging level must also be DEBUG in order to get it to output anything.
You can print the function by evaluating the name of it in the console, like so
> unknownFunc
function unknownFunc(unknown) {
alert('unknown seems to be ' + unknown);
}
this won't work for built-in functions, they will only display [native code]
instead of the source code.
EDIT: this implies that the function has been defined within the current scope.
so if you need want use this code )
import { useRoutes } from "./routes";
import { BrowserRouter as Router } from "react-router-dom";
export const App = () => {
const routes = useRoutes(true);
return (
<Router>
<div className="container">{routes}</div>
</Router>
);
};
// ./routes.js
import { Switch, Route, Redirect } from "react-router-dom";
export const useRoutes = (isAuthenticated) => {
if (isAuthenticated) {
return (
<Switch>
<Route path="/links" exact>
<LinksPage />
</Route>
<Route path="/create" exact>
<CreatePage />
</Route>
<Route path="/detail/:id">
<DetailPage />
</Route>
<Redirect path="/create" />
</Switch>
);
}
return (
<Switch>
<Route path={"/"} exact>
<AuthPage />
</Route>
<Redirect path={"/"} />
</Switch>
);
};
If you are looking for only one object to be removed, you can use
Person.findOne({_id: req.params.id}, function (error, person){
console.log("This object will get deleted " + person);
person.remove();
});
In this example, Mongoose will delete based on matching req.params.id.
If it is Long
object then You can use longValue == null
or you can use Objects.isNull(longValue)
method in Java 8 .
Please check Objects for more info.
If this is a simple project, you should be able to drag the txt file right into the project folder. Specifically, the "project folder" would be the highest level folder. I tried to do this (for a homework project that I'm doing) by putting the txt file in the src folder, but that didn't work. But finally I figured out to put it in the project file.
A good tutorial for this is http://www.vogella.com/articles/JavaIO/article.html. I used this as an intro to i/o and it helped.
This is my best solution. I used this many times.
class DictLikeClass:
...
def __getitem__(self, key):
return getattr(self, key)
def __setitem__(self, key, value):
setattr(self, key, value)
...
You can use like:
>>> d = DictLikeClass()
>>> d["key"] = "value"
>>> print(d["key"])
Basically, all Maven is telling you is that certain dependencies in your project are not available in the central maven repository. The default is to look in your local .m2 folder (local repository), and then any configured repositories in your POM, and then the central maven repository. Look at the repositories section of the Maven reference.
The problem is that the project that was checked in didn't configure the POM in such a way that all the dependencies could be found and the project could be built from scratch.
Fetch from the remote and checkout the branch.
git fetch <remote_name> && git checkout <branch_name>
E.g.:
git fetch origin && git checkout feature/XYZ-1234-Add-alerts
Yes there are two way to add a line feed:
Use the existing function from VBA vbCrLf
in the string you want to add a line feed, as such:
Dim text As String
text = "Hello" & vbCrLf & "World!"
Worksheets(1).Cells(1, 1) = text
Use the Chr()
function and pass the ASCII characters 13 and 10 in order to add a line feed, as shown bellow:
Dim text As String
text = "Hello" & Chr(13) & Chr(10) & "World!"
Worksheets(1).Cells(1, 1) = text
In both cases, you will have the same output in cell (1,1) or A1.
For numerical data you have the solution. But it is categorical data, you said. Then life gets a bit more complicated...
Well, first : The amount of association between two categorical variables is not measured with a Spearman rank correlation, but with a Chi-square test for example. Which is logic actually. Ranking means there is some order in your data. Now tell me which is larger, yellow or red? I know, sometimes R does perform a spearman rank correlation on categorical data. If I code yellow 1 and red 2, R would consider red larger than yellow.
So, forget about Spearman for categorical data. I'll demonstrate the chisq-test and how to choose columns using combn(). But you would benefit from a bit more time with Agresti's book : http://www.amazon.com/Categorical-Analysis-Wiley-Probability-Statistics/dp/0471360937
set.seed(1234)
X <- rep(c("A","B"),20)
Y <- sample(c("C","D"),40,replace=T)
table(X,Y)
chisq.test(table(X,Y),correct=F)
# I don't use Yates continuity correction
#Let's make a matrix with tons of columns
Data <- as.data.frame(
matrix(
sample(letters[1:3],2000,replace=T),
ncol=25
)
)
# You want to select which columns to use
columns <- c(3,7,11,24)
vars <- names(Data)[columns]
# say you need to know which ones are associated with each other.
out <- apply( combn(columns,2),2,function(x){
chisq.test(table(Data[,x[1]],Data[,x[2]]),correct=F)$p.value
})
out <- cbind(as.data.frame(t(combn(vars,2))),out)
Then you should get :
> out
V1 V2 out
1 V3 V7 0.8116733
2 V3 V11 0.1096903
3 V3 V24 0.1653670
4 V7 V11 0.3629871
5 V7 V24 0.4947797
6 V11 V24 0.7259321
Where V1 and V2 indicate between which variables it goes, and "out" gives the p-value for association. Here all variables are independent. Which you would expect, as I created the data at random.
store localy analytics.js, but it is not recommended by google: https://support.google.com/analytics/answer/1032389?hl=en
it is not recommended cause google can update script when they want, so just do a script that download analytics javascript each week and you will not have trouble !
By the way this solution prevent adblock from blocking google analytics scripts
Very easy, trial and error. Go to the cell you want the month in. Type the Month, go to the next cell and type the year, something weird will come up but then go to your number section click on the little arrow in the right bottom and highlight text and it will change to the year you originally typed
Issue: Your branch is based on 'origin/master', but the upstream is gone.
Solution: git branch --unset-upstream
In my thinking a user stops writing when he doesn't keep focus on that input. For this you have a function called "blur" which does stuff like
Let's project P is importing custom library L, then you must add L into
P -> Build Phases -> Embed Frameworks -> +
. That works for me.
You just do like below:
int intToCast = 1;
TargetEnum f = (TargetEnum) intToCast ;
To make sure that you only cast the right values ??and that you can throw an exception otherwise:
int intToCast = 1;
if (Enum.IsDefined(typeof(TargetEnum), intToCast ))
{
TargetEnum target = (TargetEnum)intToCast ;
}
else
{
// Throw your exception.
}
Note that using IsDefined is costly and even more than just casting, so it depends on your implementation to decide to use it or not.
For Mac users, a MUCH easier way is to do this right in the android emulator:

You can find your maven files here:
cd ~/.m2
Probably you need to copy settings.xml in your .m2
folder:
cp /usr/local/bin/apache-maven-2.2.1/conf/settings.xml .m2/
If no .m2 folder exists:
mkdir -p ~/.m2
Um, why not just:

I found this when re-using a PHP class I wrote a fair amount of time ago. I still cant remember what went there and I still have found no use for it... I actually don't even remember me writing that comment; so I literally laughed out loud when I found it.
try
{
// Some database logic
}
catch (Exception $ex)
{
// sure, it looks silly and I honestly cant remember what code used to go here... but i swear i will
// find a use for this code.... eventually....
throw $ex;
}
Now that the question is clearer, you can just do this in one grep
grep -R --include "*bills*" "put" .
With relevant flags
-R, -r, --recursive
Read all files under each directory, recursively; this is
equivalent to the -d recurse option.
--include=GLOB
Search only files whose base name matches GLOB (using wildcard
matching as described under --exclude).
You just need to set the following things before connecting to the database as below:
const mongoose = require('mongoose');
mongoose.set('useNewUrlParser', true);
mongoose.set('useFindAndModify', false);
mongoose.set('useCreateIndex', true);
mongoose.set('useUnifiedTopology', true);
mongoose.connect('mongodb://localhost/testaroo');
Also,
Replace update() with updateOne(), updateMany(), or replaceOne()
Replace remove() with deleteOne() or deleteMany().
Replace count() with countDocuments(), unless you want to count how many documents are in the whole collection (no filter).
In the latter case, use estimatedDocumentCount().
A supplementarily handy (but trivial) tip for installing older version of packages from source.
First, if you call "install.packages", it always installs the latest package from repo. If you want to install the older version of packages, say for compatibility, you can call install.packages("url_to_source", repo=NULL, type="source"). For example:
install.packages("http://cran.r-project.org/src/contrib/Archive/RNetLogo/RNetLogo_0.9-6.tar.gz", repo=NULL, type="source")
Without manually downloading packages to the local disk and switching to the command line or installing from local disk, I found it is very convenient and simplify the call (one-step).
Plus: you can use this trick with devtools library's dev_mode, in order to manage different versions of packages:
Reference: doc devtools
Here is a simplified function that returns a boolean and has no output pushed to stdout:
import subprocess, platform
def pingOk(sHost):
try:
output = subprocess.check_output("ping -{} 1 {}".format('n' if platform.system().lower()=="windows" else 'c', sHost), shell=True)
except Exception, e:
return False
return True
You could also try string addition:
print " "+'"'+'a word that needs quotation marks'+'"'
Try below code :-
1.
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
2.
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth(); // deprecated
int height = display.getHeight(); // deprecated
or
int width = getWindowManager().getDefaultDisplay().getWidth();
int height = getWindowManager().getDefaultDisplay().getHeight();
3.
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
metrics.heightPixels;
metrics.widthPixels;
If you want an alternative to pickle
or json
, you can use klepto
.
>>> init = {'y': 2, 'x': 1, 'z': 3}
>>> import klepto
>>> cache = klepto.archives.file_archive('memo', init, serialized=False)
>>> cache
{'y': 2, 'x': 1, 'z': 3}
>>>
>>> # dump dictionary to the file 'memo.py'
>>> cache.dump()
>>>
>>> # import from 'memo.py'
>>> from memo import memo
>>> print memo
{'y': 2, 'x': 1, 'z': 3}
With klepto
, if you had used serialized=True
, the dictionary would have been written to memo.pkl
as a pickled dictionary instead of with clear text.
You can get klepto
here: https://github.com/uqfoundation/klepto
dill
is probably a better choice for pickling then pickle
itself, as dill
can serialize almost anything in python. klepto
also can use dill
.
You can get dill
here: https://github.com/uqfoundation/dill
The additional mumbo-jumbo on the first few lines are because klepto
can be configured to store dictionaries to a file, to a directory context, or to a SQL database. The API is the same for whatever you choose as the backend archive. It gives you an "archivable" dictionary with which you can use load
and dump
to interact with the archive.
Execute in a terminal:
mongo // To go to shell
show databases // To show all existing databases.
use <DATA_BASE> // To switch to the wanted database.
db.dropDatabase() // To remove the current database.
You can use RegExMatch
:
=IF(RegExMatch(A1;"Bla");"YES";"NO")
#include<stdio.h>
void main ()
{
int num;
printf ("=====This Program Converts ASCII to Alphabet!=====\n");
printf ("Enter ASCII: ");
scanf ("%d", &num);
printf("%d is ASCII value of '%c'", num, (char)num );
}
#include<stdio.h>
void main ()
{
char alphabet;
printf ("=====This Program Converts Alphabet to ASCII code!=====\n");
printf ("Enter Alphabet: ");
scanf ("%c", &alphabet);
printf("ASCII value of '%c' is %d", alphabet, (char)alphabet );
}
For a pure python module you can find the source by looking at themodule.__file__
.
The datetime module, however, is written in C, and therefore datetime.__file__
points to a .so file (there is no datetime.__file__
on Windows), and therefore, you can't see the source.
If you download a python source tarball and extract it, the modules' code can be found in the Modules subdirectory.
For example, if you want to find the datetime code for python 2.6, you can look at
Python-2.6/Modules/datetimemodule.c
You can also find the latest Mercurial version on the web at https://hg.python.org/cpython/file/tip/Modules/_datetimemodule.c
Its painful to hear people are still suffering at the hands of *{COPY} whatever the version. I am a seasoned batch and Bash script writer and I recommend rsync , you can run this within cygwin (cygwin.org) or you can locate some binaries floating around . and you can redirect output to 2>&1 to some log file like out.log for later analysing. Good luck people its time to love life again . =M. Kaan=

Using the -n /usr/local/bin flag does work, BUT I had to come back to this page every time I wanted to update a package again. So I figured out a permanent fix for this.
For those interested in fixing this permanently:
Create a ~/.gemrc file
vim .gemrc
With the following content:
:gemdir:
- ~/.gem/ruby
install: -n /usr/local/bin
Now you can run your command normally without the -n flag.
Enjoy!
A real literal suffixed by M or m is of type decimal (money). For example, the literals 1m, 1.5m, 1e10m, and 123.456M are all of type decimal. This literal is converted to a decimal value by taking the exact value, and, if necessary, rounding to the nearest representable value using banker's rounding. Any scale apparent in the literal is preserved unless the value is rounded or the value is zero (in which latter case the sign and scale will be 0). Hence, the literal 2.900m will be parsed to form the decimal with sign 0, coefficient 2900, and scale 3.
There are two ways to do the redirect. Both apply to either subprocess.Popen
or subprocess.call
.
Set the keyword argument shell = True
or executable = /path/to/the/shell
and specify the command just as you have it there.
Since you're just redirecting the output to a file, set the keyword argument
stdout = an_open_writeable_file_object
where the object points to the output
file.
subprocess.Popen
is more general than subprocess.call
.
Popen
doesn't block, allowing you to interact with the process while it's running, or continue with other things in your Python program. The call to Popen
returns a Popen
object.
call
does block. While it supports all the same arguments as the Popen
constructor, so you can still set the process' output, environmental variables, etc., your script waits for the program to complete, and call
returns a code representing the process' exit status.
returncode = call(*args, **kwargs)
is basically the same as calling
returncode = Popen(*args, **kwargs).wait()
call
is just a convenience function. It's implementation in CPython is in subprocess.py:
def call(*popenargs, timeout=None, **kwargs):
"""Run command with arguments. Wait for command to complete or
timeout, then return the returncode attribute.
The arguments are the same as for the Popen constructor. Example:
retcode = call(["ls", "-l"])
"""
with Popen(*popenargs, **kwargs) as p:
try:
return p.wait(timeout=timeout)
except:
p.kill()
p.wait()
raise
As you can see, it's a thin wrapper around Popen
.
My solution is to add the ID field as the LAST field in the table, thus bulk insert ignores it and it gets automatic values. Clean and simple ...
For instance, if inserting into a temp table:
CREATE TABLE #TempTable
(field1 varchar(max), field2 varchar(max), ...
ROW_ID int IDENTITY(1,1) NOT NULL)
Note that the ROW_ID
field MUST always be specified as LAST field!
You can't.
One workaround is to create clone environment, and then remove original one:
(remember about deactivating current environment with deactivate
on Windows and source deactivate
on macOS/Linux)
conda create --name new_name --clone old_name
conda remove --name old_name --all # or its alias: `conda env remove --name old_name`
There are several drawbacks of this method:
--offline
flag to disable it,There is an open issue requesting this feature.
If you have a method that you want to throw an error but you want to do some cleanup in your method beforehand you can put the code that will throw the exception inside a try block, then put the cleanup in the catch block, then throw the error.
try {
//Dangerous code: could throw an error
} catch (Exception e) {
//Cleanup: make sure that this methods variables and such are in the desired state
throw e;
}
This way the try/catch block is not actually handling the error but it gives you time to do stuff before the method terminates and still ensures that the error is passed on to the caller.
An example of this would be if a variable changed in the method then that variable was the cause of an error. It may be desirable to revert the variable.
The proper way to do this is to use multiple tables and JOIN
them in your queries.
For example:
CREATE TABLE person (
`id` INT NOT NULL PRIMARY KEY,
`name` VARCHAR(50)
);
CREATE TABLE fruits (
`fruit_name` VARCHAR(20) NOT NULL PRIMARY KEY,
`color` VARCHAR(20),
`price` INT
);
CREATE TABLE person_fruit (
`person_id` INT NOT NULL,
`fruit_name` VARCHAR(20) NOT NULL,
PRIMARY KEY(`person_id`, `fruit_name`)
);
The person_fruit
table contains one row for each fruit a person is associated with and effectively links the person
and fruits
tables together, I.E.
1 | "banana"
1 | "apple"
1 | "orange"
2 | "straberry"
2 | "banana"
2 | "apple"
When you want to retrieve a person and all of their fruit you can do something like this:
SELECT p.*, f.*
FROM person p
INNER JOIN person_fruit pf
ON pf.person_id = p.id
INNER JOIN fruits f
ON f.fruit_name = pf.fruit_name
onCreate(Bundle)
is called when the activity first starts up. You can use it to perform one-time initialization such as creating the user interface. onCreate()
takes one parameter that is either null or some state information previously saved by the onSaveInstanceState
.
The java application takes too long to respond(maybe due start-up/jvm being cold) thus you get the proxy error.
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /lin/Campaignn.jsp.
As Albert Maclang said amending the http timeout configuration may fix the issue. I suspect the java application throws a 500+ error thus the apache gateway error too. You should look in the logs.
$this->db->select('id, name, price, author, category, language, ISBN, publish_date');
$this->db->from('tbl_books');
click()
to the QMainWindow custom slot you have created).Code example:
MainWindow.h
// ...
include "newwindow.h"
// ...
public slots:
void openNewWindow();
// ...
private:
NewWindow *mMyNewWindow;
// ...
}
MainWindow.cpp
// ...
MainWindow::MainWindow()
{
// ...
connect(mMyButton, SIGNAL(click()), this, SLOT(openNewWindow()));
// ...
}
// ...
void MainWindow::openNewWindow()
{
mMyNewWindow = new NewWindow(); // Be sure to destroy your window somewhere
mMyNewWindow->show();
// ...
}
This is an example on how display a custom new window. There are a lot of ways to do this.
Just wrap the float, boolean, int or similar in an NSNumber.
For structs, I don't know of a handy solution, but you could make a separate ObjC class that owns such a struct.
use this in your view
<EditText
....
....
android:imeOptions="actionDone"
android:id="@+id/edtName"
/>
This single line of code solved the problem for me:
event.currentTarget.getAttribute('data-tag')
This is borderline programming, but look into using tr:
$ echo "this is just a test" | tr -s ' ' | tr ' ' '_'
Should do it. The first invocation squeezes the spaces down, the second replaces with underscore. You probably need to add TABs and other whitespace characters, this is for spaces only.
AFAIK, you don't need to map the UNC path to a drive letter in order to establish credentials for a server. I regularly used batch scripts like:
net use \\myserver /user:username password
:: do something with \\myserver\the\file\i\want.xml
net use /delete \\my.server.com
However, any program running on the same account as your program would still be able to access everything that username:password
has access to. A possible solution could be to isolate your program in its own local user account (the UNC access is local to the account that called NET USE
).
Note: Using SMB accross domains is not quite a good use of the technology, IMO. If security is that important, the fact that SMB lacks encryption is a bit of a damper all by itself.
What about using .splitlines()
?
for line in textData.splitlines():
print(line)
lineResult = libLAPFF.parseLine(line)
The accepted answer by Aristotle will show all reachable commits, including non-stash-like commits. To filter out the noise:
git fsck --no-reflog | \
awk '/dangling commit/ {print $3}' | \
xargs git log --no-walk --format="%H" \
--grep="WIP on" --min-parents=3 --max-parents=3
This will only include commits which have exactly 3 parent commits (which a stash will have), and whose message includes "WIP on".
Keep in mind, that if you saved your stash with a message (e.g. git stash save "My newly created stash"
), this will override the default "WIP on..." message.
You can display more information about each commit, e.g. display the commit message, or pass it to git stash show
:
git fsck --no-reflog | \
awk '/dangling commit/ {print $3}' | \
xargs git log --no-walk --format="%H" \
--grep="WIP on" --min-parents=3 --max-parents=3 | \
xargs -n1 -I '{}' bash -c "\
git log -1 --format=medium --color=always '{}'; echo; \
git stash show --color=always '{}'; echo; echo" | \
less -R
As @alucic mentioned, use:
composer require vendor/package:version
or you can use:
composer update vendor/package:version
You should probably review this StackOverflow post about differences between composer install and composer update.
Related to question about version numbers, you can review Composer documentation on versions, but here in short:
So, with Tilde you will get automatic updates of patches but minor and major versions will not be updated. However, if you use Caret you will get patches and minor versions, but you will not get major (breaking changes) versions.
Tilde Version is considered a "safer" approach, but if you are using reliable dependencies (well-maintained libraries) you should not have any problems with Caret Version (because minor changes should not be breaking changes.
anyItem has never been declared as a variable, so it makes sense that it causes an error. But more importantly, you have code after a return statement and this will cause an unreachable code error.
if (document.getElementById('remember').checked) {
alert("checked");
}
else {
alert("You didn't check it! Let me check it for you.");
}
A class contains data field descriptions (or properties, fields, data members, attributes), i.e., field types and names, that will be associated with either per-instance or per-class state variables at program run time.
Use this code:
HttpContext.Current.Server.MapPath("~")
Detailed Reference:
Server.MapPath
specifies the relative or virtual path to map to a physical directory.
Server.MapPath(".")
returns the current physical directory of the
file (e.g. aspx) being executedServer.MapPath("..")
returns the parent directoryServer.MapPath("~")
returns the physical path to the root of the
applicationServer.MapPath("/")
returns the physical path to the root of the
domain name (is not necessarily the same as the root of the
application)An example:
Let's say you pointed a web site application (http://www.example.com/) to
C:\Inetpub\wwwroot
and installed your shop application (sub web as virtual directory in IIS, marked as application) in
D:\WebApps\shop
For example, if you call Server.MapPath
in following request:
http://www.example.com/shop/products/GetProduct.aspx?id=2342
then:
Server.MapPath(".") returns D:\WebApps\shop\products
Server.MapPath("..") returns D:\WebApps\shop
Server.MapPath("~") returns D:\WebApps\shop
Server.MapPath("/") returns C:\Inetpub\wwwroot
Server.MapPath("/shop") returns D:\WebApps\shop
If Path starts with either a forward (/) or backward slash (), the MapPath
method returns a path as if Path were a full, virtual path.
If Path doesn't start with a slash, the MapPath
method returns a path relative to the directory of the request being processed.
Note: in C#, @ is the verbatim literal string operator meaning that the string should be used "as is" and not be processed for escape sequences.
Footnotes
Server.MapPath(null)
and Server.MapPath("")
will produce this effect too.

If you want to use inetpub/wwwroot/aspnet as your application, remove this line :
Line 26: and any other lines which define MachineToApplication beyond application level
If you want to use d:\inetpub\wwwroot\aspnet\begin\chapter02\ as your application, create an IIS Application which points to d:\inetpub\wwwroot\aspnet\begin\chapter02\
maybe you can refer link above. For my application, my web.config store in d:\inetpub\wwwroot\aspnet\begin\chapter02\ and when i move the web.config to d:\inetpub\wwwroot\aspnet and the problem is solve. Please check also does your application have two web.config file.

Nc is a link to nmap-ncat.
It would be nice to use nmap-ncat in your puppet, because NC is a virtual name of nmap-ncat.
Puppet cannot understand the links/virtualnames
your puppet should be:

ensure => installed;

![mvc architecture][1]
Model–view–controller (MVC) is a software architectural pattern for implementing user interfaces. It divides a given software application into three interconnected parts, so as to separate internal representations of information from the ways that information is presented to or accepted from the user.
I'm using Xcode 6 beta 5 on a Swift project, for an iOS 7 app.
Here is what I did, and it works:
info.plist:
This might be due to the maximum number of characters allowed for a specific column, like in sql one field might have following Data Type nvarchar(5)
but the number of characters entered from the user is more than the specified, hence the error arises.
You need the stat call, and the file name:
my $last_mod_time = (stat ($file))[9];
Perl also has a different version:
my $last_mod_time = -M $file;
but that value is relative to when the program started. This is useful for things like sorting, but you probably want the first version.
Not much of a keyboard shortcut but the TODO comments in the source show up in the method/function dropdown at the top of the editor.
So for example:
// TODO: Some task that needs to be done.
shows up in the drop down list of methods and functions so you can jump to it directly.
Most Java IDEs show a marker for these task tags in the scrollbar, which is nicer, but this also works.
In C++20 you'll be able to do:
auto s = std::format("{}{}{}", "Hello world, ", myInt, niceToSeeYouString);
Until then you could do the same with the {fmt} library:
auto s = fmt::format("{}{}{}", "Hello world, ", myInt, niceToSeeYouString);
Disclaimer: I'm the author of {fmt}.
On Unix systems that supports it (not macOS it seems):
if getent passwd "$username" >/dev/null; then
printf 'User %s exists\n' "$username"
else
printf 'User %s does not exist\n' "$username"
fi
This has the advantage that it will query any directory service that may be in use (YP/NIS or LDAP etc.) and the local password database file.
The issue with grep -q "$username" /etc/passwd
is that it will give a false positive when there is no such user, but something else matches the pattern. This could happen if there is a partial or exact match somewhere else in the file.
For example, in my passwd
file, there is a line saying
build:*:21:21:base and xenocara build:/var/empty:/bin/ksh
This would provoke a valid match on things like cara
and enoc
etc., even though there are no such users on my system.
For a grep
solution to be correct, you will need to properly parse the /etc/passwd
file:
if cut -d ':' -f 1 /etc/passwd | grep -qxF "$username"; then
# found
else
# not found
fi
... or any other similar test against the first of the :
-delimited fields.
You can use the CSS property pointer-events
to disable the click event on any element:
https://developer.mozilla.org/en-US/docs/Web/CSS/pointer-events
// To disable:
document.getElementById('id').style.pointerEvents = 'none';
// To re-enable:
document.getElementById('id').style.pointerEvents = 'auto';
// Use '' if you want to allow CSS rules to set the value
Here is a JsBin: http://jsbin.com/oyAhuRI/1/edit
I tried several approaches.
# BY {dplyr}
data.table(ID = c(rep("A", 5), rep("B",5)),
Quarter = c(1:5, 1:5),
value = rnorm(10)) -> df1
df1 %<>% dplyr::mutate(ID = as.factor(ID),
Quarter = as.character(Quarter))
# check classes
dplyr::glimpse(df1)
# Observations: 10
# Variables: 3
# $ ID (fctr) A, A, A, A, A, B, B, B, B, B
# $ Quarter (chr) "1", "2", "3", "4", "5", "1", "2", "3", "4", "5"
# $ value (dbl) -0.07676732, 0.25376110, 2.47192852, 0.84929175, -0.13567312, -0.94224435, 0.80213218, -0.89652819...
, or otherwise
# from list to data.table using data.table::setDT
list(ID = as.factor(c(rep("A", 5), rep("B",5))),
Quarter = as.character(c(1:5, 1:5)),
value = rnorm(10)) %>% setDT(list.df) -> df2
class(df2)
# [1] "data.table" "data.frame"
You could try:
agg <- aggregate(list(x$val1, x$val2, x$val3, x$val4), by = list(x$id1, x$id2), mean)
It could also mean that the current Java type system version isn't good enough for your case. There were several JSR propositions / hacks to fix this: Type tokens, Super Type Tokens, Class.cast().
If you really need this supression, narrow it down as much as possible (e.g. don't put it onto the class itself or onto a long method). An example:
public List<String> getALegacyListReversed() {
@SuppressWarnings("unchecked") List<String> list =
(List<String>)legacyLibrary.getStringList();
Collections.reverse(list);
return list;
}
Add the following css to disable the default scroll:
body {
overflow: hidden;
}
And change the #content
css to this to make the scroll only on content body:
#content {
max-height: calc(100% - 120px);
overflow-y: scroll;
padding: 0px 10%;
margin-top: 60px;
}
Edit:
Actually, I'm not sure what was the issue you were facing, since it seems that your css is working. I have only added the HTML and the header css statement:

Found another solution for the same. It will be more helpful.
START C:\"Program Files (x86)"\Test\"Test Automation"\finger.exe ConfigFile="C:\Users\PCName\Desktop\Automation\Documents\Validation_ZoneWise_Default.finger.Config"
finger.exe is a parent program that is calling config solution. Note: if your path folder name consists of spaces, then do not forget to add "".
Extracted from this comment by bkDJ:
^(?!bar$).*
The nice property of this solution is that it's possible to clearly negate (exclude) multiple words:
^(?!bar$|foo$|banana$).*
Simpler way (if your only keyword is "code" ) may be:
string ErrorCode = yourString.Split(new string[]{"code"}, StringSplitOptions.None).Last();
yes, its possible, run this command:
lets say you have user called thoko
grant select any table, insert any table, delete any table, update any table to thoko;
note: worked on oracle database
If you're outside the request-response handling, you can still:
import os
import signal
sig = getattr(signal, "SIGKILL", signal.SIGTERM)
os.kill(os.getpid(), sig)
In C Pi is defined in math.h: #define M_PI 3.14159265358979323846
I assume this is *nix?
Use "here document":
sqlplus -s user/pass <<+EOF
select 1 from dual;
+EOF
EDIT: I should have tried your second example. It works, too (even in Windows, sans ticks):
$ echo 'select 1 from dual;'|sqlplus -s user/pw

This should be the complete answer. As suggested by @GDanger . Extend WebView to override the scroll methods and embed the custom webview within layout xml.
public class ScrollDisabledWebView extends WebView {
private boolean scrollEnabled = false;
public ScrollDisabledWebView(Context context) {
super(context);
initView(context);
}
public ScrollDisabledWebView(Context context, AttributeSet attributeSet) {
super(context, attributeSet);
initView(context);
}
// this is important. Otherwise it throws Binary Inflate Exception.
private void initView(Context context) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
protected boolean overScrollBy(int deltaX, int deltaY, int scrollX, int scrollY,
int scrollRangeX, int scrollRangeY, int maxOverScrollX,
int maxOverScrollY, boolean isTouchEvent) {
if (scrollEnabled) {
return super.overScrollBy(deltaX, deltaY, scrollX, scrollY,
scrollRangeX, scrollRangeY, maxOverScrollX, maxOverScrollY, isTouchEvent);
}
return false;
}
@Override
public void scrollTo(int x, int y) {
if (scrollEnabled) {
super.scrollTo(x, y);
}
}
@Override
public void computeScroll() {
if (scrollEnabled) {
super.computeScroll();
}
}
}
And then embed in layout file as follows
<com.sample.apps.ScrollDisabledWebView
android:id="@+id/webView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true"
tools:context="com.sample.apps.HomeActivity"/>
Then in the Activity, use some additional methods for disabling scrollbars too.
ScrollDisabledWebView webView = (ScrollDisabledWebView) findViewById(R.id.webView);
webView.setVerticalScrollBarEnabled(false);
webView.setHorizontalScrollBarEnabled(false);
Try this command.
python -m pip install --user pip==9.0.1
(Header CSS:)
<style>
a {
color: #ccc; /* original colour state*/
}
a:active {
color: #F66;
}
a[tabindex]:focus {

outline: none;
}
</style>
(Body HTML:)
<a href="javascript:;" style="font-size:36px; text-decoration:none;" tabindex="1">click me ♥</a>
Try this style instead, it modifies the template itself. In there you can change everything you need to transparent:
<Style TargetType="{x:Type TabItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid>
<Border Name="Border" Margin="0,0,0,0" Background="Transparent"

RecognizesAccessKey="True">
<ContentPresenter.LayoutTransform>
<RotateTransform Angle="270" />
</ContentPresenter.LayoutTransform>
</ContentPresenter>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Panel.ZIndex" Value="100" />
<Setter TargetName="Border" Property="Background" Value="Red" />
<Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,0" />
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter TargetName="Border" Property="Background" Value="DarkRed" />
<Setter TargetName="Border" Property="BorderBrush" Value="Black" />
<Setter Property="Foreground" Value="DarkGray" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
To modify a value every time a block of code runs without having to break execution flow:
The "Logpoints" feature in the debugger is designed to let you log arbitrary values to the console without breaking. It evaluates code inside the flow of execution, which means you can actually use it to change values on the fly without stopping.
Right-click a line number and choose "Logpoint," then enter the assignment expression. It looks something like this:
I find it super useful for setting values to a state not otherwise easy to reproduce, without having to rebuild my project with debug lines in it. REMEMBER to delete the breakpoint when you're done!
We can simply declare more than one Controller in the same module. Here's an example:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js">
</script>
<title> New Page </title>
</head>
<body ng-app="mainApp"> <!-- if we remove ng-app the add book button [show/hide] will has no effect -->
<h2> Books </h2>
<!-- <input type="checkbox" ng-model="hideShow" ng-init="hideShow = false"></input> -->
<input type = "button" value = "Add Book"ng-click="hideShow=(hideShow ? false : true)"> </input>
<div ng-app = "mainApp" ng-controller = "bookController" ng-if="hideShow">
Enter book name: <input type = "text" ng-model = "book.name"><br>
Enter book category: <input type = "text" ng-model = "book.category"><br>
Enter book price: <input type = "text" ng-model = "book.price"><br>
Enter book author: <input type = "text" ng-model = "book.author"><br>
You are entering book: {{book.bookDetails()}}
</div>
<script>
var mainApp = angular.module("mainApp", []);
mainApp.controller('bookController', function($scope) {
$scope.book = {
name: "",
category: "",
price:"",
author: "",
bookDetails: function() {
var bookObject;
bookObject = $scope.book;
return "Book name: " + bookObject.name + '\n' + "Book category: " + bookObject.category + " \n" + "Book price: " + bookObject.price + " \n" + "Book Author: " + bookObject.author;
}
};
});
</script>
<h2> Albums </h2>
<input type = "button" value = "Add Album"ng-click="hideShow2=(hideShow2 ? false : true)"> </input>
<div ng-app = "mainApp" ng-controller = "albumController" ng-if="hideShow2">
Enter Album name: <input type = "text" ng-model = "album.name"><br>
Enter Album category: <input type = "text" ng-model = "album.category"><br>
Enter Album price: <input type = "text" ng-model = "album.price"><br>
Enter Album singer: <input type = "text" ng-model = "album.singer"><br>
You are entering Album: {{album.albumDetails()}}
</div>
<script>
//no need to declare this again ;)
//var mainApp = angular.module("mainApp", []);
mainApp.controller('albumController', function($scope) {
$scope.album = {
name: "",
category: "",

singer: "",
albumDetails: function() {
var albumObject;
albumObject = $scope.album;
return "Album name: " + albumObject.name + '\n' + "album category: " + albumObject.category + "\n" + "Book price: " + albumObject.price + "\n" + "Album Singer: " + albumObject.singer;
}
};
});
</script>

Why you would want to do this is beyond me, since id is supposed to be unique in a document. However, browsers tend to be quite lax on this, so if you really must use getElementById for this purpose, you can do it like this:
function whywouldyoudothis() {
var n = document.getElementById("non-unique-id");
var a = [];
var i;
while(n) {
a.push(n);
n.id = "a-different-id";
n = document.getElementById("non-unique-id");
}
for(i = 0;i < a.length; ++i) {
a[i].id = "non-unique-id";
}
return a;
}
However, this is silly, and I wouldn't trust this to work on all browsers forever. Although the HTML DOM spec defines id as readwrite, a validating browser will complain if faced with more than one element with the same id.
EDIT: Given a valid document, the same effect could be achieved thus:
function getElementsById(id) {
return [document.getElementById(id)];
}
>>> from_date="Mon Feb 15 2010"
>>> import time
>>> conv=time.strptime(from_date,"%a %b %d %Y")
>>> time.strftime("%d/%m/%Y",conv)
'15/02/2010'
You must set the bounds properties to fit that frame. frame its superview properties, and bounds limit the frame in the view itself coordinate system.
Use make (chan int)
instead of nil
. The first value has to be the same type that your map holds.
package main
import "fmt"
func main() {
var sessions = map[string] chan int{}
sessions["somekey"] = make(chan int)
fmt.Printf ("%d\n", len(sessions)) // 1
// Remove somekey's value from sessions
delete(sessions, "somekey")
fmt.Printf ("%d\n", len(sessions)) // 0
}
UPDATE: Corrected my answer.
Depending on what you want to accomplish, you might replace INSERT with INSERT IGNORE in your file. This will avoid generating an error for the rows that you are trying to insert and already exist.
For other types, check out the types module:
>>> import types
>>> x = "mystring"
>>> isinstance(x, types.StringType)
True
>>> x = 5
>>> isinstance(x, types.IntType)
True
>>> x = None
>>> isinstance(x, types.NoneType)
True
P.S. Typechecking is a bad idea.
This problem can be solved efficiently using the numpy_indexed library (disclaimer: I am its author); which was created to address problems of this type. npi.indices can be viewed as an n-dimensional generalisation of list.index. It will act on nd-arrays (along a specified axis); and also will look up multiple entries in a vectorized manner as opposed to a single item at a time.
a = np.random.rand(50, 60, 70)
i = np.random.randint(0, len(a), 40)
b = a[i]
import numpy_indexed as npi
assert all(i == npi.indices(a, b))
This solution has better time complexity (n log n at worst) than any of the previously posted answers, and is fully vectorized.
also had same problem once,
if you are unable to solve the problem you can run the following command on command line
chrome.exe --user-data-dir="C://Chrome dev session" --disable-web-security
Note: you have to navigate to the installation path of your chrome.
For example:cd C:\Program Files\Google\Chrome\Application
A developer session chrome browser will be opened, you can now launch your app on the new chrome browse.
I hope this should be helpful
This may be useful:
var serializer = new JavaScriptSerializer();
dynamic jsonObject = serializer.Deserialize<dynamic>(json);
Where "json" is the string that contains the JSON values. Then to retrieve the values from the jsonObject you may use
myProperty = Convert.MyPropertyType(jsonObject["myProperty"]);
Changing MyPropertyType to the proper type (ToInt32, ToString, ToBoolean, etc).
Different SQL, same principle. Only insert if the clause in where not exists fails

I was wondering about this specifically for building software in Debian (the installed Debian system can be a 32-bit version with a 32 bit kernel, libraries, etc., or it can be a 64-bit version with stuff compiled for the 64-bit rather than 32-bit compatibility mode).
Debian packages themselves need to know what architecture they are for (of course) when they actually create the package with all of its metadata, including platform architecture, so there is a packaging tool that outputs it for other packaging tools and scripts to use, called dpkg-architecture. It includes both what it's configured to build for, as well as the current host. (Normally these are the same though.) Example output on a 64-bit machine:
DEB_BUILD_ARCH=amd64
DEB_BUILD_ARCH_OS=linux
DEB_BUILD_ARCH_CPU=amd64
DEB_BUILD_GNU_CPU=x86_64
DEB_BUILD_GNU_SYSTEM=linux-gnu
DEB_BUILD_GNU_TYPE=x86_64-linux-gnu
DEB_HOST_ARCH=amd64
DEB_HOST_ARCH_OS=linux
DEB_HOST_ARCH_CPU=amd64
DEB_HOST_GNU_CPU=x86_64
DEB_HOST_GNU_SYSTEM=linux-gnu
DEB_HOST_GNU_TYPE=x86_64-linux-gnu
You can print just one of those variables or do a test against their values with command line options to dpkg-architecture.
I have no idea how dpkg-architecture deduces the architecture, but you could look at its documentation or source code (dpkg-architecture and much of the dpkg system in general are Perl).
You shouldn't use flag e
(or eval
in general).
You can also use T-Regx library
pattern('(^|_)([a-z])')->replace($word)->by()->group(2)->callback('strtoupper');
With support for C++11 initializer lists it is very easy:
#include <iostream>
#include <vector>
#include <string>
using namespace std;
using Strings = vector<string>;
void foo( Strings const& strings )
{
for( string const& s : strings ) { cout << s << endl; }
}
auto main() -> int
{
foo( Strings{ "hi", "there" } );
}
Lacking that (e.g. for Visual C++ 10.0) you can do things like this:
#include <iostream>
#include <vector>
#include <string>
using namespace std;
typedef vector<string> Strings;
void foo( Strings const& strings )
{
for( auto it = begin( strings ); it != end( strings ); ++it )
{
cout << *it << endl;
}
}
template< class Elem >
vector<Elem>& r( vector<Elem>&& o ) { return o; }
template< class Elem, class Arg >
vector<Elem>& operator<<( vector<Elem>& v, Arg const& a )
{
v.push_back( a );
return v;
}
int main()
{
foo( r( Strings() ) << "hi" << "there" );
}
According to the help of cmake
:
-C <initial-cache>
Pre-load a script to populate the cache.
When cmake is first run in an empty build tree, it creates a CMakeCache.txt file and populates it with customizable settings for the project. This option may be used to specify a file from
which to load cache entries before the first pass through the project's cmake listfiles. The loaded entries take priority over the project's default values. The given file should be a CMake
script containing SET commands that use the CACHE option, not a cache-format file.
You make be able to create files like gcc_compiler.txt
and clang_compiler.txt
to includes all relative configuration in CMake syntax.
Clang Example (clang_compiler.txt):
set(CMAKE_C_COMPILER "/usr/bin/clang" CACHE string "clang compiler" FORCE)
Then run it as
GCC:
cmake -C gcc_compiler.txt XXXXXXXX
Clang:
cmake -C clang_compiler.txt XXXXXXXX
Just use Python's standard string formatting methods:
>>> "{0:.2}".format(1.234232)
'1.2'
>>> "{0:.3}".format(1.234232)
'1.23'
If you are using a Python version under 2.6, use
>>> "%f" % 1.32423
'1.324230'
>>> "%.2f" % 1.32423
'1.32'
>>> "%d" % 1.32423
'1'
For IIS 7.5+ and Rewrite 2.0 you can use:
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Headers" value="Origin, X-Requested-With, Content-Type, Accept" />
<add name="Access-Control-Allow-Methods" value="POST,GET,OPTIONS,PUT,DELETE" />
</customHeaders>
</httpProtocol>
<rewrite>
<outboundRules>
<clear />
<rule name="AddCrossDomainHeader">
<match serverVariable="RESPONSE_Access_Control_Allow_Origin" pattern=".*" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="true">
<add input="{HTTP_ORIGIN}" pattern="(http(s)?://((.+\.)?domain1\.com|(.+\.)?domain2\.com|(.+\.)?domain3\.com))" />
</conditions>
<action type="Rewrite" value="{C:0}" />
</rule>
</outboundRules>
</rewrite>
</system.webServer>
Explaining the server variable RESPONSE_Access_Control_Allow_Origin
portion:
In Rewrite you can use any string after RESPONSE_
and it will create the Response Header using the rest of the word as the header name (in this case Access-Control-Allow-Origin). Rewrite uses underscores "_" instead of dashes "-" (rewrite converts them to dashes)
Explaining the server variable HTTP_ORIGIN
:
Similarly, in Rewrite you can grab any Request Header using HTTP_
as the prefix. Same rules with the dashes (use underscores "_" instead of dashes "-").
I would use a "wait"-command for a specific time (milliseconds) of your own choice. The application executes until the line you want to inspect and then continues after the time expired.
Include the <time.h>
header:
clock_t wait;
wait = clock();
while (clock() <= (wait + 5000)) // Wait for 5 seconds and then continue
;
wait = 0;
Both methods have their problems.
If the subclass changes the identity, then you need to compare their actual classes. Otherwise, you violate the symmetric property. For instance, different types of Person
s should not be considered equivalent, even if they have the same name.
However, some subclasses don't change identity and these need to use instanceof
. For instance, if we have a bunch of immutable Shape
objects, then a Rectangle
with length and width of 1 should be equal to the unit Square
.
In practice, I think the former case is more likely to be true. Usually, subclassing is a fundamental part of your identity and being exactly like your parent except you can do one little thing does not make you equal.
Use dict.items(); it can be as simple as following:
ship = collections.OrderedDict(ship.items())
I've tried all of the above nothing was working.. so I had to make my ImageView static public static ImageView texture;
and then texture = (ImageView) findViewById(R.id.texture_back);
, I don't think it's a good approach though but this really worked for my case :)
For Ubuntu, you can try:
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
For Cent OS/RHEL try :
sudo yum install zlib.i686 ncurses-libs.i686 bzip2-libs.i686
Then, re-install the Android Studio and get success.
Here's a link that helped me with this.
It uses PagedList.MVC NuGet package. I'll try to summarize the steps
Install the PagedList.MVC NuGet package
Build project
Add using PagedList;
to the controller
Modify your action to set page
public ActionResult ListMyItems(int? page)
{
List list = ItemDB.GetListOfItems();
int pageSize = 3;
int pageNumber = (page ?? 1);
return View(list.ToPagedList(pageNumber, pageSize));
}
Add paging links to the bottom of your view
@*Your existing view*@
Page @(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) of @Model.PageCount
@Html.PagedListPager(Model, page => Url.Action("Index",
new { page, sortOrder = ViewBag.CurrentSort, currentFilter = ViewBag.CurrentFilter }))
The raw_json_encode() function above did not solve me the problem (for some reason, the callback function raised an error on my PHP 5.2.5 server).
But this other solution did actually work.
https://www.experts-exchange.com/questions/28628085/json-encode-fails-with-special-characters.html
Credits should go to Marco Gasi. I just call his function instead of calling json_encode():
function jsonRemoveUnicodeSequences( $json_struct )
{
return preg_replace( "/\\\\u([a-f0-9]{4})/e", "iconv('UCS-4LE','UTF-8',pack('V', hexdec('U$1')))", json_encode( $json_struct ) );
}
you can use
val resultDf = PersonDf.join(ProfileDf, PersonDf("personId") === ProfileDf("personId"))
or shorter and more flexible (as you can easely specify more than 1 columns for joining)
val resultDf = PersonDf.join(ProfileDf,Seq("personId"))
As stated by numerous other answers, list.remove()
will work, but throw a ValueError
if the item wasn't in the list. With python 3.4+, there's an interesting approach to handling this, using the suppress contextmanager:
from contextlib import suppress
with suppress(ValueError):
a.remove('b')
Here is my working code :
<!DOCTYPE html>

<style>
ul#proList{list-style-position: inside}
li.item{list-style:none; padding:5px;}

</head>
<body>
<div id="renderList"></div>
</body>
<script>
(function(){
var ul = document.createElement('ul');
ul.setAttribute('id','proList');
productList = ['Electronics Watch','House wear Items','Kids wear','Women Fashion'];
document.getElementById('renderList').appendChild(ul);
productList.forEach(renderProductList);
function renderProductList(element, index, arr) {
var li = document.createElement('li');
li.setAttribute('class','item');
ul.appendChild(li);
li.innerHTML=li.innerHTML + element;
}
})();
</script>

First of all, there are many, many ways of matching items within a HTML document. Start with this reference to see some of the available selectors/patterns which you can use to apply a style rule to an element(s).
http://www.w3.org/TR/selectors/
Match all div
s which are direct descendants of #main
.
#main > div
Match all div
s which are direct or indirect descendants of #main
.
#main div
Match the first div
which is a direct descendant of #sections
.
#main > div:first-child
Match a div
with a specific attribute.
#main > div[foo="bar"]
The Underscore.String library has a function that does Insert
insert(string, index, substring) => string
like so
insert("Hello ", 6, "world");
// => "Hello world"
I believe you intended it more this way:
foreach (DataTable table in ds.Tables)
{
foreach (DataRow dr in table.Rows)
{
DateTime TaskStart = DateTime.Parse(dr["TaskStart"].ToString());
TaskStart.ToString("dd-MMMM-yyyy");
rpt.SetParameterValue("TaskStartDate", TaskStart);
}
}
You always accessed your first row in your dataset.
Please try this,
$ms = Person::where('name', 'Foo Bar')->first();
$persons = Person::order_by('list_order', 'ASC')->get();
return View::make('viewname')->with(compact('persons','ms'));
On MSDN, the documentation for Task.Run Method (Action) provides this example which shows how to run a method asynchronously from main
:
using System;
using System.Threading;
using System.Threading.Tasks;
public class Example
{
public static void Main()
{
ShowThreadInfo("Application");
var t = Task.Run(() => ShowThreadInfo("Task") );
t.Wait();
}
static void ShowThreadInfo(String s)
{
Console.WriteLine("{0} Thread ID: {1}",
s, Thread.CurrentThread.ManagedThreadId);
}
}
// The example displays the following output:
// Application thread ID: 1
// Task thread ID: 3
Note this statement that follows the example:
The examples show that the asynchronous task executes on a different thread than the main application thread.
So, if instead you want the task to run on the main application thread, see the answer by @StephenCleary.
And regarding the thread on which the task runs, also note Stephen's comment on his answer:
You can use a simple
Wait
orResult
, and there's nothing wrong with that. But be aware that there are two important differences: 1) allasync
continuations run on the thread pool rather than the main thread, and 2) any exceptions are wrapped in anAggregateException
.
(See Exception Handling (Task Parallel Library) for how to incorporate exception handling to deal with an AggregateException
.)
Finally, on MSDN from the documentation for Task.Delay Method (TimeSpan), this example shows how to run an asynchronous task that returns a value:
using System;
using System.Threading.Tasks;
public class Example
{
public static void Main()
{
var t = Task.Run(async delegate
{
await Task.Delay(TimeSpan.FromSeconds(1.5));
return 42;
});
t.Wait();
Console.WriteLine("Task t Status: {0}, Result: {1}",
t.Status, t.Result);
}
}
// The example displays the following output:
// Task t Status: RanToCompletion, Result: 42
Note that instead of passing a delegate
to Task.Run
, you can instead pass a lambda function like this:
var t = Task.Run(async () =>
{
await Task.Delay(TimeSpan.FromSeconds(1.5));
return 42;
});
Just add this:
-webkit-filter: drop-shadow(5px 5px 5px #fff);
filter: drop-shadow(5px 5px 5px #fff);
example:
<img class="home-tab-item-img" src="img/search.png">
.home-tab-item-img{
-webkit-filter: drop-shadow(5px 5px 5px #fff);
filter: drop-shadow(5px 5px 5px #fff);
}
You can do it, but it requires two steps. Here's how:
git fetch <remote-git-url> <branch> && git cherry-pick FETCH_HEAD
Replace <remote-git-url>
with the url or path to the repository you want cherry-pick from.
Replace <branch>
with the branch or tag name you want to cherry-pick from the remote repository.
You can replace FETCH_HEAD
with a git SHA from the branch.
Updated: modified based on @pkalinow's feedback.
You can use map
:
List<String> names =
personList.stream()
.map(Person::getName)
.collect(Collectors.toList());
EDIT :
In order to combine the Lists of friend names, you need to use flatMap
:
List<String> friendNames =
personList.stream()
.flatMap(e->e.getFriends().stream())

I would like to make a addon for tiago's answer:
Suppose you're hiding element using ng-show
and adding a required
attribute on the same:
<div ng-show="false">
<input required name="something" ng-model="name"/>
</div>
will throw an error something like :
An invalid form control with name='' is not focusable
This is because you just cannot impose required
validation on hidden
elements. Using ng-required
makes it easier to conditionally apply required validation which is just awesome!!
You are right, this is related to SQL injection, which is a vulnerability that allows a malicioius user to execute arbitrary statements against your database. This old time favorite XKCD comic illustrates the concept:
In your example, if you just use:
var query = "SELECT empSalary from employee where salary = " + txtSalary.Text;
// and proceed to execute this query
You are open to SQL injection. For example, say someone enters txtSalary:
1; UPDATE employee SET salary = 9999999 WHERE empID = 10; --
1; DROP TABLE employee; --
// etc.
When you execute this query, it will perform a SELECT
and an UPDATE
or DROP
, or whatever they wanted. The --
at the end simply comments out the rest of your query, which would be useful in the attack if you were concatenating anything after txtSalary.Text
.
The correct way is to use parameterized queries, eg (C#):
SqlCommand query = new SqlCommand("SELECT empSalary FROM employee
WHERE salary = @sal;");
query.Parameters.AddWithValue("@sal", txtSalary.Text);
With that, you can safely execute the query.
For reference on how to avoid SQL injection in several other languages, check bobby-tables.com, a website maintained by a SO user.
Why not just use the WordPress get_query_var()
function? WordPress Code Reference
// Test if the query exists at the URL
if ( get_query_var('ppc') ) {
// If so echo the value
echo get_query_var('ppc');
}
Since get_query_var can only access query parameters available to WP_Query, in order to access a custom query var like 'ppc', you will also need to register this query variable within your plugin or functions.php
by adding an action during initialization:
add_action('init','add_get_val');
function add_get_val() {
global $wp;
$wp->add_query_var('ppc');
}
Or by adding a hook to the query_vars filter:
function add_query_vars_filter( $vars ){
$vars[] = "ppc";
return $vars;
}
add_filter( 'query_vars', 'add_query_vars_filter' );
There are 2 popular state machine packages in NuGet.
Appccelerate.StateMachine (13.6K downloads + 3.82K of legacy version (bbv.Common.StateMachine))
StateMachineToolkit (1.56K downloads)
The Appccelerate lib has good documentation, but it does not support .NET 4, so I chose StateMachineToolkit for my project.
The problem with your attempt at the psql
command line is the direction of the slashes:
newTestDB-# /i E:\db-rbl-restore-20120511_Dump-20120514.sql # incorrect
newTestDB-# \i E:/db-rbl-restore-20120511_Dump-20120514.sql # correct
To be clear, psql
commands start with a backslash, so you should have put \i
instead. What happened as a result of your typo is that psql
ignored everything until finding the first \
, which happened to be followed by db
, and \db
happens to be the psql
command for listing table spaces, hence why the output was a List of tablespaces. It was not a listing of "default tables of PostgreSQL" as you said.
Further, it seems that psql
expects the filepath
argument to delimit directories using the forward slash regardless of OS (thus on Windows this would be counter-intuitive).
It is worth noting that your attempt at "elevating permissions" had no relation to the outcome of the command you attempted to execute. Also, you did not say what caused the supposed "Permission Denied" error.
Finally, the extension on the dump file does not matter, in fact you don't even need an extension. Indeed, pgAdmin
suggests a .backup
extension when selecting a backup filename, but you can actually make it whatever you want, again, including having no extension at all. The problem is that pgAdmin
seems to only allow a "Restore" of "Custom or tar" or "Directory" dumps (at least this is the case in the MAC OS X version of the app), so just use the psql
\i
command as shown above.
On ubuntu you can add this PPA Repository and use it to install python 3.7: https://launchpad.net/~jonathonf/+archive/ubuntu/python-3.7
Or a different PPA that provides several Python versions is Deadsnakes: https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa
See also here: https://askubuntu.com/questions/865554/how-do-i-install-python-3-6-using-apt-get (I know it says 3.6 in the url, but the deadsnakes ppa also contains 3.7 so you can use it for 3.7 just the same)
If you want "official" you'd have to install it from the sources from the site, get the code (which you already downloaded) and do this:
tar -xf Python-3.7.0.tar.xz
cd Python-3.7.0
./configure
make
sudo make install <-- sudo is required.
This might take a while
After many attempts I was finally able to get this working. Essentially what I did was download and use the vmware converter to merge the two disks into one. After that I was able to attach the newly created disk to VitrualBox.
The steps involved are very simple:
BEFORE YOU DO ANYTHING!
1) MAKE A BACKUP!!! Even if you follow these instruction, you could screw things up, so make a backup. Just shutdown the VM and then make a copy of the directory where VM resides.
2) Uninstall VMware Tools from the VM that you are going to convert. If for some reason you forget this step, you can still uninstall it after getting everything running under VirtualBox by following these steps. Do yourself the favor and just do it now.
NOW THE FUN PART!!!
1) Download and install the VMware Converter. I used 5.0.1 build-875114, just use the latest.
2) Download and install VirtualBox
3) Fire up VMWare convertor:
4) Click on Convert machine
6) Browse to the .vmx
for your VM and click Next
.
7) Give the new VM a name and select the location where you want to put it. Click Next
8) Click Next
on the Options
screen. You shouldn't have to change anything here.
9) Click Finish
on the Summary
screen to begin the conversion.
10) The conversion should start. This will take a LOOONG time so be patient.
11) Hopefully all went well, if it did, you should see that the conversion is completed:
12) Now open up VirtualBox and click New
.
13) Give your VM a name and select what Type
and Version
it is. Click Next
.
14) Select the size of the memory you want to give it. Click Next
.
15) For the Hard Drive
, click Use and existing hard drive file
and select the newly converted .vmdk
file.
16) Now Click Settings
and select the Storage
menu. The issue is that by default VirtualBox will add the drive as an IDE. This won't work and we need as we need to put it on a SCSI controller.
17) Select the IDE controller and the Remove Controller
button.
18) Now click the Add Controller
button and select Add SCSI Controller
19) Click the Add Hard Disk
button.
20) Click Choose existing disk
21) Select your .vmdk
file. Click OK
22) Select the System
menu.
23) Click Enable IO APIC
. Then click OK
24) Congrats!!! Your VM is now confgiured! Click Start
to startup the VM!
Given enum
public enum PublishMode { Edit, View }
you can do it like here
void MyMethod(PublishMode? mode)
{
var publishMode = mode ?? PublishMode.Edit;
//or
if (mode?? PublishMode.Edit == someValue)
....
}
The database.yml is the file where you set up all the information to connect to the database. It differs depending on the kind of DB you use. You can find more information about this in the Rails Guide or any tutorial explaining how to setup a rails project.
The information in the database.yml file is scoped by environment, allowing you to get a different setting for testing, development or production. It is important that you keep those distinct if you don't want the data you use for development deleted by mistake while running your test suite.
Regarding source control, you should not commit this file but instead create a template file for other developers (called database.yml.template
). When deploying, the convention is to create this database.yml file in /shared/config
directly on the server.
With SVN: svn propset svn:ignore config "database.yml"
With Git: Add config/database.yml
to the .gitignore file or with git-extra git ignore config/database.yml
... and now, some examples:
SQLite
adapter: sqlite3
database: db/db_dev_db.sqlite3
pool: 5
timeout: 5000
MYSQL
adapter: mysql
database: my_db
hostname: 127.0.0.1
username: root
password:
socket: /tmp/mysql.sock
pool: 5
timeout: 5000
MongoDB with MongoID (called mongoid.yml, but basically the same thing)
host: <%= ENV['MONGOID_HOST'] %>
port: <%= ENV['MONGOID_PORT'] %>
username: <%= ENV['MONGOID_USERNAME'] %>
password: <%= ENV['MONGOID_PASSWORD'] %>
database: <%= ENV['MONGOID_DATABASE'] %>
# slaves:
# - host: slave1.local
# port: 27018
# - host: slave2.local
# port: 27019
Similarly using Bash regexp. Shall be able to snatch any key/value pair.
key="Body"
re="\"($key)\": \"([^\"]*)\""
while read -r l; do
if [[ $l =~ $re ]]; then
name="${BASH_REMATCH[1]}"
value="${BASH_REMATCH[2]}"
echo "$name=$value"
else
echo "No match"
fi
done
Regular expression can be tuned to match multiple spaces/tabs or newline(s). Wouldn't work if value has embedded "
. This is an illustration. Better to use some "industrial" parser :)
I am using Debian but this solution should work fine with Ubuntu.
You have to add a line in the neo4j-service script.
Here is what I have done :
nano /etc/init.d/neo4j-service
Add « ulimit –n 40000 » just before the start-stop-daemon line in the do_start section
Note that I am using version 2.0 Enterprise edition. Hope this will help you.
You can also send (POST
) multiple params within {}
and add it.
Example:
$http.post(config.url+'/api/assign-badge/', {employeeId:emp_ID,bType:selectedCat,badge:selectedBadge})
.then(function(response) {
NotificationService.displayNotification('Info', 'Successfully Assigned!', true);
}, function(response) {
});
where employeeId
, bType
(Badge Catagory), and badge
are three parameters.

The 2 domains mydomain.com
and subdomain.mydomain.com
can only share cookies if the domain is explicitly named in the Set-Cookie
header. Otherwise, the scope of the cookie is restricted to the request host. (This is referred to as a "host-only cookie". See What is a host only cookie?)
For instance, if you sent the following header from subdomain.mydomain.com
, then the cookie won't be sent for requests to mydomain.com
:
Set-Cookie: name=value
However if you use the following, it will be usable on both domains:
Set-Cookie: name=value; domain=mydomain.com
This cookie will be sent for any subdomain of mydomain.com, including nested subdomains like subsub.subdomain.mydomain.com
.
In RFC 2109, a domain without a leading dot meant that it could not be used on subdomains, and only a leading dot (.mydomain.com
) would allow it to be used across multiple subdomains (but not the top-level domain, so what you ask was not possible in the older spec).
However, all modern browsers respect the newer specification RFC 6265, and will ignore any leading dot, meaning you can use the cookie on subdomains as well as the top-level domain.
In summary, if you set a cookie like the second example above from mydomain.com
, it would be accessible by subdomain.mydomain.com
, and vice versa. This can also be used to allow sub1.mydomain.com
and sub2.mydomain.com
to share cookies.

In theory SMTP can be handled by either TCP, UDP, or some 3rd party protocol.
As defined in RFC 821, RFC 2821, and RFC 5321:
SMTP is independent of the particular transmission subsystem and requires only a reliable ordered data stream channel.
In addition, the Internet Assigned Numbers Authority has allocated port 25 for both TCP and UDP for use by SMTP.
In practice however, most if not all organizations and applications only choose to implement the TCP protocol. For example, in Microsoft's port listing port 25 is only listed for TCP and not UDP.
The big difference between TCP and UDP that makes TCP ideal here is that TCP checks to make sure that every packet is received and re-sends them if they are not whereas UDP will simply send packets and not check for receipt. This makes UDP ideal for things like streaming video where every single packet isn't as important as keeping a continuous flow of packets from the server to the client.
Considering SMTP, it makes more sense to use TCP over UDP. SMTP is a mail transport protocol, and in mail every single packet is important. If you lose several packets in the middle of the message the recipient might not even receive the message and if they do they might be missing key information. This makes TCP more appropriate because it ensures that every packet is delivered.
Check the information in registry : HKEY_CURRENT_USER\SOFTWARE\Microsoft\VSCommon\Keychain\Accounts and delete the related keys under Accounts section.
Clear the cache in these paths:
%localappdata%\Microsoft\TeamTest
%localappdata%\Microsoft\Team Foundation
%localappdata%\Microsoft\VisualStudio
%appdata%\Roaming\Microsoft\VisualStudio
Hope this will work.
Note: By doing this may clear all the cookies and caches and load the Visual Studio New.
A realtime priority thread can never be pre-empted by timer interrupts and runs at a higher priority than any other thread in the system. As such a CPU bound realtime priority thread can totally ruin a machine.
Creating realtime priority threads requires a privilege (SeIncreaseBasePriorityPrivilege) so it can only be done by administrative users.
For Vista and beyond, one option for applications that do require that they run at realtime priorities is to use the Multimedia Class Scheduler Service (MMCSS) and let it manage your threads priority. The MMCSS will prevent your application from using too much CPU time so you don't have to worry about tanking the machine.
You can parse the geolocation through the addresses. Create an Array with jquery like this:
//follow this structure
var addressesArray = [
'Address Str.No, Postal Area/city'
]
//loop all the addresses and call a marker for each one
for (var x = 0; x < addressesArray.length; x++) {
$.getJSON('http://maps.googleapis.com/maps/api/geocode/json?address='+addressesArray[x]+'&sensor=false', null, function (data) {
var p = data.results[0].geometry.location
var latlng = new google.maps.LatLng(p.lat, p.lng);
//it will place marker based on the addresses, which they will be translated as geolocations.
var aMarker= new google.maps.Marker({
position: latlng,
map: map
});
});
}
Also please note that Google limit your results if you don't have a business account with them, and you my get an error if you use too many addresses.
I ran into this issue today. Here is my hacky solution.
I needed a fixed position element to transition up by 100 pixels as it loaded.
var delay = (ms) => new Promise(res => setTimeout(res, ms));
async function animateView(startPosition,elm){
for(var i=0; i<101; i++){
elm.style.top = `${(startPosition-i)}px`;
await delay(1);
}
}
1: The LayoutInflater
takes your layout XML-files and creates different View-objects from its contents.
2: The adapters are built to reuse Views, when a View is scrolled so that is no longer visible, it can be used for one of the new Views appearing. This reused View is the convertView
. If this is null it means that there is no recycled View and we have to create a new one, otherwise we should use it to avoid creating a new.
3: The parent
is provided so you can inflate your view into that for proper layout parameters.
All these together can be used to effectively create the view that will appear in your list (or other view that takes an adapter):
public View getView(int position, @Nullable View convertView, ViewGroup parent){
if (convertView == null) {
//We must create a View:
convertView = inflater.inflate(R.layout.my_list_item, parent, false);
}
//Here we can do changes to the convertView, such as set a text on a TextView
//or an image on an ImageView.
return convertView;
}
Notice the use of the LayoutInflater
, that parent
can be used as an argument for it, and how convertView
is reused.
File.Create(string)
returns an instance of the FileStream
class. You can call the Stream.Close()
method on this object in order to close it and release resources that it's using:
var myFile = File.Create(myPath);
myFile.Close();
However, since FileStream
implements IDisposable
, you can take advantage of the using
statement (generally the preferred way of handling a situation like this). This will ensure that the stream is closed and disposed of properly when you're done with it:
using (var myFile = File.Create(myPath))
{
// interact with myFile here, it will be disposed automatically
}
Why do you want to call cmd.exe
? cmd.exe
is a command line (shell). If you want to change directory, use os.chdir("C:\\")
. Try not to call external commands if Python can provide it. In fact, most operating system commands are provide through the os
module (and sys). I suggest you take a look at os
module documentation to see the various methods available.
You have an error (misspelling):
Sessions::get('msg')// an extra 's' on end
Should be:
Session::get('msg')
I think, now it should work, it does for me.
$dir = "mytheme/images/myimages";
$dh = opendir($dir);
while (false !== ($filename = readdir($dh))) {
$files[] = $filename;
}
$images=preg_grep ('/\.jpg$/i', $files);
Very fast because you only scan the needed directory.
You can modify with the following
<li><a href="./Index" class="elements"><span>Clients</span></a></li>
The extra dot means you are in the same controller. If you want change the controller to a different controller then you can write this
<li><a href="../newController/Index" class="elements"><span>Clients</span></a></li>
So before MySQL 8.0 there is no ROW_NUMBER() function. Accpted answer rewritten to support older versions of MySQL:
SET @row_number = 0;
SELECT t.A, t.B, t.C, (@row_number:=@row_number + 1) AS number
FROM dbo.tableZ AS t ORDER BY t.A;
Try this from different folder:
sudo tar -cvjSf folder.tar.bz2 folder/*
This is all you need to do:
var myVariable;
$.ajax({
'async': false,
'type': "POST",
'global': false,
'dataType': 'html',
'url': "ajax.php?first",
'data': { 'request': "", 'target': 'arrange_url', 'method': 'method_target' },
'success': function (data) {
myVariable = data;
}
});
NOTE: Use of "async" has been depreciated. See https://xhr.spec.whatwg.org/.
Maksym Kozlenko has a nice solution, and others come close to unlocking it's full potential but then miss completely to realized that you can define any sequence of characters, and use it's length as the Base. Which is why I like this slightly modified version of his solution, because it can work for base 16, or base 17, and etc.
For example, what if you wanted letters and numbers, but don't like I's for looking like 1's and O's for looking like 0's. You can define any sequence this way. Below is a form of a "Base 36" that skips the I and O to create a "modified base 34". Un-comment the hex line instead to run as hex.
declare @value int = 1234567890
DECLARE @seq varchar(100) = '0123456789ABCDEFGHJKLMNPQRSTUVWXYZ' -- modified base 34
--DECLARE @seq varchar(100) = '0123456789ABCDEF' -- hex
DECLARE @result varchar(50)
DECLARE @digit char(1)
DECLARE @baseSize int = len(@seq)
DECLARE @workingValue int = @value
SET @result = SUBSTRING(@seq, (@workingValue%@baseSize)+1, 1)
WHILE @workingValue > 0
BEGIN
SET @digit = SUBSTRING(@seq, ((@workingValue/@baseSize)%@baseSize)+1, 1)
SET @workingValue = @workingValue/@baseSize
IF @workingValue <> 0 SET @result = @digit + @result
END
select @value as Value, @baseSize as BaseSize, @result as Result
Value, BaseSize, Result
1234567890, 34, T5URAA
I also moved value over to a working value, and then work from the working value copy, as a personal preference.
Below is additional for reversing the transformation, for any sequence, with the base defined as the length of the sequence.
declare @value varchar(50) = 'T5URAA'
DECLARE @seq varchar(100) = '0123456789ABCDEFGHJKLMNPQRSTUVWXYZ' -- modified base 34
--DECLARE @seq varchar(100) = '0123456789ABCDEF' -- hex
DECLARE @result int = 0
DECLARE @digit char(1)
DECLARE @baseSize int = len(@seq)
DECLARE @workingValue varchar(50) = @value
DECLARE @PositionMultiplier int = 1
DECLARE @digitPositionInSequence int = 0
WHILE len(@workingValue) > 0
BEGIN
SET @digit = right(@workingValue,1)
SET @digitPositionInSequence = CHARINDEX(@digit,@seq)
SET @result = @result + ( (@digitPositionInSequence -1) * @PositionMultiplier)
--select @digit, @digitPositionInSequence, @PositionMultiplier, @result
SET @workingValue = left(@workingValue,len(@workingValue)-1)
SET @PositionMultiplier = @PositionMultiplier * @baseSize
END
select @value as Value, @baseSize as BaseSize, @result as Result
From MSDN:
Use of two sequential underscore characters ( __ ) at the beginning of an identifier, or a single leading underscore followed by a capital letter, is reserved for C++ implementations in all scopes. You should avoid using one leading underscore followed by a lowercase letter for names with file scope because of possible conflicts with current or future reserved identifiers.
This means that you can use a single underscore as a member variable prefix, as long as it's followed by a lower-case letter.
This is apparently taken from section 17.4.3.1.2 of the C++ standard, but I can't find an original source for the full standard online.
See also this question.
Watch out! There is a bunch of knowledge rot in this thread (stuff that used to be true and now isn't).
To avoid false-positive rejections of actual email addresses in the current and future world, and from anywhere in the world, you need to know at least the high-level concept of RFC 3490, "Internationalizing Domain Names in Applications (IDNA)". I know folks in US and A often aren't up on this, but it's already in widespread and rapidly increasing use around the world (mainly the non-English dominated parts).
The gist is that you can now use addresses like mason@??.com and wildwezyr@fahrvergnügen.net. No, this isn't yet compatible with everything out there (as many have lamented above, even simple qmail-style +ident addresses are often wrongly rejected). But there is an RFC, there's a spec, it's now backed by the IETF and ICANN, and--more importantly--there's a large and growing number of implementations supporting this improvement that are currently in service.
I didn't know much about this development myself until I moved back to Japan and started seeing email addresses like hei@??.ca and Amazon URLs like this:
http://www.amazon.co.jp/????????-???????-??????????/b/ref=topnav_storetab_e?ie=UTF8&node=3210981
I know you don't want links to specs, but if you rely solely on the outdated knowledge of hackers on Internet forums, your email validator will end up rejecting email addresses that non-English-speaking users increasingly expect to work. For those users, such validation will be just as annoying as the commonplace brain-dead form that we all hate, the one that can't handle a + or a three-part domain name or whatever.
So I'm not saying it's not a hassle, but the full list of characters "allowed under some/any/none conditions" is (nearly) all characters in all languages. If you want to "accept all valid email addresses (and many invalid too)" then you have to take IDN into account, which basically makes a character-based approach useless (sorry), unless you first convert the internationalized email addresses (dead since September 2015, used to be like this—a working alternative is here) to Punycode.
After doing that you can follow (most of) the advice above.
I had a problem with this and I finally figured this out. Until today I was using a really old version of jQuery, version 1.8.2.
Everywhere where I had used dialog
I had initialised it with the following position option:
$.dialog({
position: "center"
});
However, I found that removing position: "center"
or replacing it with the correct syntax didn't do the trick, for example:
$.dialog({
position: {
my: "center",
at: "center",
of: window
}
});
Although the above is correct, I was also using option
to set the position as center when I loaded the page, in the old way, like so:
// The wrong old way of keeping a dialog centered
passwordDialogInstance.dialog("option", "position", "center");
This was causing all of my dialog windows to stick to the top left of the view port.
I had to replace all instances of this with the correct new syntax below:
passwordDialogInstance.dialog(
"option",
"position",
{ my: "center", at: "center", of: window }
);
Adding an object to header we use the examples used here,yet i will complete
ObjectFactory objectFactory = new ObjectFactory();
CabeceraCR cabeceraCR =objectFactory.createCabeceraCR();
cabeceraCR.setUsuario("xxxxx");
cabeceraCR.setClave("xxxxx");
With object factory we create the object asked to pass on the header. The to add to the header
WSBindingProvider bp = (WSBindingProvider)wsXXXXXXSoap;
bp.setOutboundHeaders(
// Sets a simple string value as a header
Headers.create(jaxbContext,objectFactory.createCabeceraCR(cabeceraCR))
);
We used the WSBindingProvider to add the header. The object will have some error if used directly so we use the method
objectFactory.createCabeceraCR(cabeceraCR)
This method will create a JAXBElement like this on the object Factory
@XmlElementDecl(namespace = "http://www.creditreport.ec/", name = "CabeceraCR")
public JAXBElement<CabeceraCR> createCabeceraCR(CabeceraCR value) {
return new JAXBElement<CabeceraCR>(_CabeceraCR_QNAME, CabeceraCR.class, null, value);
}
And the jaxbContext we obtained like this:
jaxbContext = (JAXBRIContext) JAXBContext.newInstance(CabeceraCR.class.getPackage().getName());
This will add the object to the header.
This will convert n seconds into d days, h hours, m minutes, and s seconds.
from datetime import datetime, timedelta
def GetTime():
sec = timedelta(seconds=int(input('Enter the number of seconds: ')))
d = datetime(1,1,1) + sec
print("DAYS:HOURS:MIN:SEC")
print("%d:%d:%d:%d" % (d.day-1, d.hour, d.minute, d.second))
Code posted by you is correct and should have worked. But check exactly what you have in the char*
. If the correct value is to big to be represented, functions will return a positive or negative HUGE_VAL
. Check what you have in the char*
against maximum values that float
and double
can represent on your computer.
Check this page for strtod
reference and this page for atof
reference.
I have tried the example you provided in both Windows and Linux and it worked fine.
You can use Character.toString(char)
. Note that this method simply returns a call to String.valueOf(char)
, which also works.
As others have noted, string concatenation works as a shortcut as well:
String s = "" + 's';
But this compiles down to:
String s = new StringBuilder().append("").append('s').toString();
which is less efficient because the StringBuilder
is backed by a char[]
(over-allocated by StringBuilder()
to 16
), only for that array to be defensively copied by the resulting String
.
String.valueOf(char)
"gets in the back door" by wrapping the char
in a single-element array and passing it to the package private constructor String(char[], boolean)
, which avoids the array copy.
Work with:
ALTER TABLE `table` CHANGE `cust_fax` `cust_fax` VARCHAR(60) NULL DEFAULT NULL;
If you want the quick and dirty way and don't worry about XSS attack, use params.merge
to keep previous parameters. e.g.
<%= link_to 'Link', params.merge({:per_page => 20}) %>
see: https://stackoverflow.com/a/4174493/445908
Otherwise , check this answer: params.merge and cross site scripting
<a href="#" onClick="window.open('http://www.yahoo.com', '_blank')">test</a>
Easy as that.
Or without JS
<a href="http://yahoo.com" target="_blank">test</a>
I would suggest to use a variable instead of a public field:
public class Variables
{
private static string name = "";
public static string Name
{
get { return name; }
set { name = value; }
}
}
From another class, you call your variable like this:
public class Main
{
public void DoSomething()
{
string var = Variables.Name;
}
}
