If you want the display dimensions in pixels you can use getSize
:
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
If you're not in an Activity
you can get the default Display
via WINDOW_SERVICE
:
WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
If you are in a fragment and want to acomplish this just use Activity.WindowManager (in Xamarin.Android) or getActivity().getWindowManager() (in java).
Before getSize
was introduced (in API level 13), you could use the getWidth
and getHeight
methods that are now deprecated:
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth(); // deprecated
int height = display.getHeight(); // deprecated
For the use case you're describing however, a margin/padding in the layout seems more appropriate.
Another way is: DisplayMetrics
A structure describing general information about a display, such as its size, density, and font scaling. To access the DisplayMetrics members, initialize an object like this:
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
We can use widthPixels
to get information for:
"The absolute width of the display in pixels."
Example:
Log.d("ApplicationTagName", "Display width in px is " + metrics.widthPixels);
Api level 30 update
final WindowMetrics metrics = windowManager.getCurrentWindowMetrics();
// Gets all excluding insets
final WindowInsets windowInsets = metrics.getWindowInsets();
Insets insets = windowInsets.getInsetsIgnoreVisibility(WindowInsets.Type.navigationBars()
| WindowInsets.Type.displayCutout());
int insetsWidth = insets.right + insets.left;
int insetsHeight = insets.top + insets.bottom;
// Legacy size that Display#getSize reports
final Rect bounds = metrics.getBounds();
final Size legacySize = new Size(bounds.width() - insetsWidth,
bounds.height() - insetsHeight);

Another approach that no one has mentioned is to add case insensitive finders into ActiveRecord::Base. Details can be found here. The advantage of this approach is that you don't have to modify every model, and you don't have to add the lower()
clause to all your case insensitive queries, you just use a different finder method instead.
SSIS doesn't implicitly convert data types, so you need to do it explicitly. The Excel connection manager can only handle a few data types and it tries to make a best guess based on the first few rows of the file. This is fully documented in the SSIS documentation.
You have several options:
INSERT
into the real destination table using CAST
or CONVERT
to convert the dataYou might also want to note the comments in the Import Wizard documentation about data type mappings.

Here are three possibilities:
foo = """
this is
a multi-line string.
"""
def f1(foo=foo): return iter(foo.splitlines())
def f2(foo=foo):
retval = ''
for char in foo:
retval += char if not char == '\n' else ''
if char == '\n':
yield retval
retval = ''
if retval:
yield retval
def f3(foo=foo):
prevnl = -1
while True:
nextnl = foo.find('\n', prevnl + 1)
if nextnl < 0: break
yield foo[prevnl + 1:nextnl]
prevnl = nextnl
if __name__ == '__main__':
for f in f1, f2, f3:
print list(f())
Running this as the main script confirms the three functions are equivalent. With timeit
(and a * 100
for foo
to get substantial strings for more precise measurement):
$ python -mtimeit -s'import asp' 'list(asp.f3())'
1000 loops, best of 3: 370 usec per loop
$ python -mtimeit -s'import asp' 'list(asp.f2())'
1000 loops, best of 3: 1.36 msec per loop
$ python -mtimeit -s'import asp' 'list(asp.f1())'
10000 loops, best of 3: 61.5 usec per loop
Note we need the list()
call to ensure the iterators are traversed, not just built.
IOW, the naive implementation is so much faster it isn't even funny: 6 times faster than my attempt with find
calls, which in turn is 4 times faster than a lower-level approach.
Lessons to retain: measurement is always a good thing (but must be accurate); string methods like splitlines
are implemented in very fast ways; putting strings together by programming at a very low level (esp. by loops of +=
of very small pieces) can be quite slow.
Edit: added @Jacob's proposal, slightly modified to give the same results as the others (trailing blanks on a line are kept), i.e.:
from cStringIO import StringIO
def f4(foo=foo):
stri = StringIO(foo)
while True:
nl = stri.readline()
if nl != '':
yield nl.strip('\n')
else:
raise StopIteration
Measuring gives:
$ python -mtimeit -s'import asp' 'list(asp.f4())'
1000 loops, best of 3: 406 usec per loop
not quite as good as the .find
based approach -- still, worth keeping in mind because it might be less prone to small off-by-one bugs (any loop where you see occurrences of +1 and -1, like my f3
above, should automatically trigger off-by-one suspicions -- and so should many loops which lack such tweaks and should have them -- though I believe my code is also right since I was able to check its output with other functions').
But the split-based approach still rules.
An aside: possibly better style for f4
would be:
from cStringIO import StringIO
def f4(foo=foo):
stri = StringIO(foo)
while True:
nl = stri.readline()
if nl == '': break
yield nl.strip('\n')
at least, it's a bit less verbose. The need to strip trailing \n
s unfortunately prohibits the clearer and faster replacement of the while
loop with return iter(stri)
(the iter
part whereof is redundant in modern versions of Python, I believe since 2.3 or 2.4, but it's also innocuous). Maybe worth trying, also:
return itertools.imap(lambda s: s.strip('\n'), stri)
or variations thereof -- but I'm stopping here since it's pretty much a theoretical exercise wrt the strip
based, simplest and fastest, one.

The standard way to do this is as follows:
Provide:
and get in return a Integer between min and max, inclusive.
Random rand = new Random();
// nextInt as provided by Random is exclusive of the top value so you need to add 1
int randomNum = rand.nextInt((max - min) + 1) + min;
See the relevant JavaDoc.
As explained by Aurund, Random objects created within a short time of each other will tend to produce similar output, so it would be a good idea to keep the created Random object as a field, rather than in a method.
Just want to reiterate this will work in pandas >= 0.9.1:
In [2]: read_csv('sample.csv', dtype={'ID': object})
Out[2]:

I'm creating an issue about detecting integer overflows also.
EDIT: See resolution here: https://github.com/pydata/pandas/issues/2247
Update as it helps others:
To have all columns as str, one can do this (from the comment):
pd.read_csv('sample.csv', dtype = str)
To have most or selective columns as str, one can do this:
# lst of column names which needs to be string
lst_str_cols = ['prefix', 'serial']
# use dictionary comprehension to make dict of dtypes
dict_dtypes = {x : 'str' for x in lst_str_cols}
# use dict on dtypes
pd.read_csv('sample.csv', dtype=dict_dtypes)
As far as I know you can't do this with string.Format ... you would have to handle this yourself. You could just strip out all non-numeric characters and then do something like:
string.Format("({0}) {1}-{2}",
phoneNumber.Substring(0, 3),
phoneNumber.Substring(3, 3),
phoneNumber.Substring(6));
This assumes the data has been entered correctly, which you could use regular expressions to validate.
You can do it either in XML or programmatically:
In XML:
card_view:cardBackgroundColor="@android:color/red"
Programmatically:
cardView.setCardBackgroundColor(Color.RED);
Starting with Java 8, the general purpose solution for a primitive array arr
, and a value to search val
, is:
public static int indexOf(char[] arr, char val) {
return IntStream.range(0, arr.length).filter(i -> arr[i] == val).findFirst().orElse(-1);
}
This code creates a stream over the indexes of the array with IntStream.range
, filters the indexes to keep only those where the array's element at that index is equal to the value searched and finally keeps the first one matched with findFirst
. findFirst
returns an OptionalInt
, as it is possible that no matching indexes were found. So we invoke orElse(-1)
to either return the value found or -1
if none were found.
Overloads can be added for int[]
, long[]
, etc. The body of the method will remain the same.
For object arrays, like String[]
, we could use the same idea and have the filtering step using the equals
method, or Objects.equals
to consider two null
elements equal, instead of ==
.
But we can do it in a simpler manner with:
public static <T> int indexOf(T[] arr, T val) {
return Arrays.asList(arr).indexOf(val);
}
This creates a list wrapper for the input array using Arrays.asList
and searches the index of the element with indexOf
.
This solution does not work for primitive arrays, as shown here: a primitive array like int[]
is not an Object[]
but an Object
; as such, invoking asList
on it creates a list of a single element, which is the given array, not a list of the elements of the array.
//LinearLayOut Setup
LinearLayout linearLayout= new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);
linearLayout.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT));
//ImageView Setup
ImageView imageView = new ImageView(this);
//setting image resource
imageView.setImageResource(R.drawable.play);
//setting image position
imageView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));
//adding view to layout
linearLayout.addView(imageView);
//make visible to program
setContentView(linearLayout);
Try this, works for me: ls -d /a/b/c/*
You can use getTime()
method to convert the Date
to the number of milliseconds since January 1, 1970. Then you can easy do any arithmetic operations with the dates. Of course you can convert the number back to the Date
with setTime()
. See here an example.

Based on the comments above, here is a simple test:
isunset() { [[ "${!1}" != 'x' ]] && [[ "${!1-x}" == 'x' ]] && echo 1; }
isset() { [ -z "$(isunset "$1")" ] && echo 1; }
Example:
$ unset foo; [[ $(isunset foo) ]] && echo "It's unset" || echo "It's set"
It's unset
$ foo= ; [[ $(isunset foo) ]] && echo "It's unset" || echo "It's set"
It's set
$ foo=bar ; [[ $(isunset foo) ]] && echo "It's unset" || echo "It's set"
It's set

You need to use either PHP's ImageMagick or GD functions to work with images.
With GD, for example, it's as simple as...
function resize_image($file, $w, $h, $crop=FALSE) {
list($width, $height) = getimagesize($file);
$r = $width / $height;
if ($crop) {
if ($width > $height) {
$width = ceil($width-($width*abs($r-$w/$h)));
} else {
$height = ceil($height-($height*abs($r-$w/$h)));
}
$newwidth = $w;
$newheight = $h;
} else {
if ($w/$h > $r) {
$newwidth = $h*$r;
$newheight = $h;
} else {
$newheight = $w/$r;
$newwidth = $w;
}
}
$src = imagecreatefromjpeg($file);
$dst = imagecreatetruecolor($newwidth, $newheight);
imagecopyresampled($dst, $src, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
return $dst;
}
And you could call this function, like so...
$img = resize_image(‘/path/to/some/image.jpg’, 200, 200);
From personal experience, GD's image resampling does dramatically reduce file size too, especially when resampling raw digital camera images.

GCC C minimal runnable example with x86 disassembly analysis
Let's see how GCC can automatically do tail call optimizations for us by looking at the generated assembly.
This will serve as an extremely concrete example of what was mentioned in other answers such as https://stackoverflow.com/a/9814654/895245 that the optimization can convert recursive function calls to a loop.
This in turn saves memory and improves performance, since memory accesses are often the main thing that makes programs slow nowadays.
As an input, we give GCC a non-optimized naive stack based factorial:
tail_call.c
#include <stdio.h>
#include <stdlib.h>
unsigned factorial(unsigned n) {
if (n == 1) {
return 1;
}
return n * factorial(n - 1);
}
int main(int argc, char **argv) {
int input;
if (argc > 1) {
input = strtoul(argv[1], NULL, 0);
} else {
input = 5;
}
printf("%u\n", factorial(input));
return EXIT_SUCCESS;
}
Compile and disassemble:
gcc -O1 -foptimize-sibling-calls -ggdb3 -std=c99 -Wall -Wextra -Wpedantic \
-o tail_call.out tail_call.c
objdump -d tail_call.out
where -foptimize-sibling-calls
is the name of generalization of tail calls according to man gcc
:
-foptimize-sibling-calls
Optimize sibling and tail recursive calls.
Enabled at levels -O2, -O3, -Os.
as mentioned at: How do I check if gcc is performing tail-recursion optimization?
I choose -O1
because:
-O0
. I suspect that this is because there are required intermediate transformations missing.-O3
produces ungodly efficient code that would not be very educative, although it is also tail call optimized.Disassembly with -fno-optimize-sibling-calls
:
0000000000001145 <factorial>:
1145: 89 f8 mov %edi,%eax
1147: 83 ff 01 cmp $0x1,%edi
114a: 74 10 je 115c <factorial+0x17>
114c: 53 push %rbx
114d: 89 fb mov %edi,%ebx
114f: 8d 7f ff lea -0x1(%rdi),%edi
1152: e8 ee ff ff ff callq 1145 <factorial>
1157: 0f af c3 imul %ebx,%eax
115a: 5b pop %rbx
115b: c3 retq
115c: c3 retq
With -foptimize-sibling-calls
:
0000000000001145 <factorial>:
1145: b8 01 00 00 00 mov $0x1,%eax
114a: 83 ff 01 cmp $0x1,%edi
114d: 74 0e je 115d <factorial+0x18>
114f: 8d 57 ff lea -0x1(%rdi),%edx
1152: 0f af c7 imul %edi,%eax
1155: 89 d7 mov %edx,%edi
1157: 83 fa 01 cmp $0x1,%edx
115a: 75 f3 jne 114f <factorial+0xa>
115c: c3 retq
115d: 89 f8 mov %edi,%eax
115f: c3 retq
The key difference between the two is that:
the -fno-optimize-sibling-calls
uses callq
, which is the typical non-optimized function call.
This instruction pushes the return address to the stack, therefore increasing it.
Furthermore, this version also does push %rbx
, which pushes %rbx
to the stack.
GCC does this because it stores edi
, which is the first function argument (n
) into ebx
, then calls factorial
.
GCC needs to do this because it is preparing for another call to factorial
, which will use the new edi == n-1
.
It chooses ebx
because this register is callee-saved: What registers are preserved through a linux x86-64 function call so the subcall to factorial
won't change it and lose n
.
the -foptimize-sibling-calls
does not use any instructions that push to the stack: it only does goto
jumps within factorial
with the instructions je
and jne
.
Therefore, this version is equivalent to a while loop, without any function calls. Stack usage is constant.
Tested in Ubuntu 18.10, GCC 8.2.
Basic rename (or move):
git mv <old name> <new name>
Case sensitive rename—eg. from casesensitive
to CaseSensitive
—you must use a two step:
git mv casesensitive tmp
git mv tmp CaseSensitive
(More about case sensitivity in Git…)
…followed by commit and push would be the simplest way to rename a directory in a git repo.
All above answers compares well, but if you need to use custom function for mapping, and you have numpy.ndarray
, and you need to retain the shape of array.
I have compare just two, but it will retain the shape of ndarray
. I have used the array with 1 million entries for comparison. Here I use square function, which is also inbuilt in numpy and has great performance boost, since there as was need of something, you can use function of your choice.
import numpy, time
def timeit():
y = numpy.arange(1000000)
now = time.time()
numpy.array([x * x for x in y.reshape(-1)]).reshape(y.shape)
print(time.time() - now)
now = time.time()
numpy.fromiter((x * x for x in y.reshape(-1)), y.dtype).reshape(y.shape)
print(time.time() - now)
now = time.time()
numpy.square(y)
print(time.time() - now)
Output
>>> timeit()
1.162431240081787 # list comprehension and then building numpy array
1.0775556564331055 # from numpy.fromiter
0.002948284149169922 # using inbuilt function
here you can clearly see numpy.fromiter
works great considering to simple approach, and if inbuilt function is available please use that.

mysqldump -u root -p"passwd" --no-data --add-drop-database --databases my_db_name | sed 's#/[*]!40000 DROP DATABASE IF EXISTS my_db_name;#' >my_db_name.sql
If you also want the data, remove the --no-data

OK it's not quite what the OP asked, but it's what I wanted to do :-)
As required in Question::
var string1= "foo/bar/test.html";
if(string1.contains("/"))
{
var string_parts = string1.split("/");
var result = string_parts[string_parts.length - 1];
console.log(result);
}
and for question asked on url (asked for one occurence of '=' )::
[http://stackoverflow.com/questions/24156535/how-to-split-a-string-after-a-particular-character-in-jquery][1]
var string1= "Hello how are =you";
if(string1.contains("="))
{
var string_parts = string1.split("=");
var result = string_parts[string_parts.length - 1];
console.log(result);
}
To use uint8_t
type alias, you have to include stdint.h
standard header.
First, one should check if the last character is a comma. If it exists, remove it.
if (str.indexOf(',', this.length - ','.length) !== -1) {
str = str.substring(0, str.length - 1);
}
NOTE str.indexOf(',', this.length - ','.length) can be simplified to str.indexOf(',', this.length - 1)
Also for openCV in python you can do:
img = cv2.imread('myImage.jpg')
height, width, channels = img.shape

, storing nulls in the values. This gives O(1) add, lookup and remove on the keys, and to all intents and purposes acts like a set.

A possible solution:
string filename = "C:\\MyDirectory\\MyFile.bat";
// Remove directory if present.
// Do this before extension removal incase directory has a period character.
const size_t last_slash_idx = filename.find_last_of("\\/");
if (std::string::npos != last_slash_idx)
{
filename.erase(0, last_slash_idx + 1);
}
// Remove extension if present.
const size_t period_idx = filename.rfind('.');
if (std::string::npos != period_idx)
{
filename.erase(period_idx);
}
This is an old question and I don't quite understand the business need of listening for route changes to push a route change; seems roundabout.
BUT if you ended up here because all you wanted was to update the 'page_path'
on a react-router route change for google analytics / global site tag / something similar, here's a hook you can now use. I wrote it based on the accepted answer:
useTracking.js
import { useEffect } from 'react'
import { useHistory } from 'react-router-dom'
export const useTracking = (trackingId) => {
const { listen } = useHistory()
useEffect(() => {
const unlisten = listen((location) => {
// if you pasted the google snippet on your index.html
// you've declared this function in the global
if (!window.gtag) return
window.gtag('config', trackingId, { page_path: location.pathname })
})
// remember, hooks that add listeners
// should have cleanup to remove them
return unlisten
}, [trackingId, listen])
}
You should use this hook once in your app, somewhere near the top but still inside a router. I have it on an App.js
that looks like this:
App.js
import * as React from 'react'
import { BrowserRouter, Route, Switch } from 'react-router-dom'
import Home from './Home/Home'
import About from './About/About'
// this is the file above
import { useTracking } from './useTracking'
export const App = () => {
useTracking('UA-USE-YOURS-HERE')
return (
<Switch>
<Route path="/about">
<About />
</Route>
<Route path="/">
<Home />
</Route>
</Switch>
)
}
// I find it handy to have a named export of the App
// and then the default export which wraps it with
// all the providers I need.
// Mostly for testing purposes, but in this case,
// it allows us to use the hook above,
// since you may only use it when inside a Router
export default () => (
<BrowserRouter>
<App />
</BrowserRouter>
)
You can create a very simplistic multi-dictionary, which automates to process of inserting values like this:
public class MultiDictionary<TKey, TValue> : Dictionary<TKey, List<TValue>>
{
public void Add(TKey key, TValue value)
{
if (TryGetValue(key, out List<TValue> valueList)) {
valueList.Add(value);
} else {
Add(key, new List<TValue> { value });
}
}
}
This creates an overloaded version of the Add
method. The original one allows you to insert a list of items for a key, if no entry for this entry exists yet. This version allows you to insert a single item in any case.
I found one interesting site which seems pretty detailed on how you could setup a ubuntu for iPhone development. But it's a little old from November 2008 for the SDK 2.0.
Ubuntu 8.10 for iPhone open toolchain SDK2.0
The instructions also include something about the Android SDK/Emulator which you can leave out.
hsb.s = max != 0 ? 255 * delta / max : 0;
?
is a ternary operator. It works like an if
in conjunction with the :
!=
means not equals
So, the long form of this line would be
if (max != 0) { //if max is not zero
hsb.s = 255 * delta / max;
} else {
hsb.s = 0;
}
I am using following in SSRS 2005
=Format(Globals!ExecutionTime,"MM-dd-yyyy" & " ")
& CStr(Hour(Globals!ExecutionTime)) & ":"
& CStr(Minute(Globals!ExecutionTime))
Or
=Format(Globals!ExecutionTime,"MM-dd-yyyy" & " ")
& Right("00" & CStr(Hour(Globals!ExecutionTime)), 2)
& ":"
& Right("00" & CStr(Minute(Globals!ExecutionTime)), 2)
Based on comment:
=Format(CDate(Globals!ExecutionTime), "MM-dd-yyyy hh:mm.ss")
OR
=Format(CDate(Globals!ExecutionTime), "MM-dd-yyyy HH:mm.ss")
I got the same error, but when i did as below, it resolved the issue.
Instead of writing like this:
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
use the below one:
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
Your should create ptr as follows:
char *ptr;
You have created ptr as an array of pointers to chars. The above creates a single pointer to a char.
Edit: complete code should be:
char *ptr;
char arr[5] = {'a','b','c','d','e'};
ptr = arr;
printf("\nvalue:%c", *(ptr+0));
you should calculate the complexity of algorithms used by the methods OrderBy and Sort. QuickSort has a complexity of n (log n) as i remember, where n is the length of the array.
i've searched for orderby's too, but i could not find any information even in msdn library. if you have not any same values and sorting related to only one property, i prefer to use Sort() method; if not than use OrderBy.

Update 2017-01-25. After trying few things, I decided to go with VisualBasic.dll it is easier and works better (at least for me). I let my previous answer just as reference...
Just as reference, this is how I did without passing arguments (which I can't find any reason to do so... I mean a single app with arguments that as to be passed out from one instance to another one). If file association is required, then an app should (per users standard expectation) be instanciated for each doc. If you have to pass args to existing app, I think I would used vb dll.
Not passing args (just single instance app), I prefer not registering a new Window message and not override the message loop as defined in Matt Davis Solution. Although it's not a big deal to add a VisualBasic dll, but I prefer not add a new reference just to do single instance app. Also, I do prefer instanciate a new class with Main instead of calling Shutdown from App.Startup override to ensure to exit as soon as possible.
In hope that anybody will like it... or will inspire a little bit :-)
Project startup class should be set as 'SingleInstanceApp'.

sh -x script [arg1 ...]
bash -x script [arg1 ...]
These give you a trace of what is being executed. (See also 'Clarification' near the bottom of the answer.)
Sometimes, you need to control the debugging within the script. In that case, as Cheeto reminded me, you can use:
set -x
This turns debugging on. You can then turn it off again with:
set +x
(You can find out the current tracing state by analyzing $-
, the current flags, for x
.)
Also, shells generally provide options '-n
' for 'no execution' and '-v
' for 'verbose' mode; you can use these in combination to see whether the shell thinks it could execute your script — occasionally useful if you have an unbalanced quote somewhere.
There is contention that the '-x
' option in Bash is different from other shells (see the comments). The Bash Manual says:
-x
Print a trace of simple commands, for
commands, case
commands, select
commands, and arithmetic for
commands and their arguments or associated word lists after they are expanded and before they are executed. The value of the PS4
variable is expanded and the resultant value is printed before the command and its expanded arguments.
That much does not seem to indicate different behaviour at all. I don't see any other relevant references to '-x
' in the manual. It does not describe differences in the startup sequence.
Clarification: On systems such as a typical Linux box, where '/bin/sh
' is a symlink to '/bin/bash
' (or wherever the Bash executable is found), the two command lines achieve the equivalent effect of running the script with execution trace on. On other systems (for example, Solaris, and some more modern variants of Linux), /bin/sh
is not Bash, and the two command lines would give (slightly) different results. Most notably, '/bin/sh
' would be confused by constructs in Bash that it does not recognize at all. (On Solaris, /bin/sh
is a Bourne shell; on modern Linux, it is sometimes Dash — a smaller, more strictly POSIX-only shell.) When invoked by name like this, the 'shebang' line ('#!/bin/bash
' vs '#!/bin/sh
') at the start of the file has no effect on how the contents are interpreted.
The Bash manual has a section on Bash POSIX mode which, contrary to a long-standing but erroneous version of this answer (see also the comments below), does describe in extensive detail the difference between 'Bash invoked as sh
' and 'Bash invoked as bash
'.
When debugging a (Bash) shell script, it will be sensible and sane — necessary even — to use the shell named in the shebang line with the -x
option. Otherwise, you may (will?) get different behaviour when debugging from when running the script.

Hi I know this was asked a while ago but I've just figured this out and it might help someone else. Not sure if this is exactly what you're looking for but this is how I call a stored proc and view the output using SQL Developer.
In SQL Developer when viewing the proc, right click and choose 'Run' or select Ctrl+F11 to bring up the Run PL/SQL window. This creates a template with the input and output params which you need to modify. My proc returns a sys_refcursor. The tricky part for me was declaring a row type that is exactly equivalent to the select stmt / sys_refcursor being returned by the proc:
DECLARE
P_CAE_SEC_ID_N NUMBER;
P_FM_SEC_CODE_C VARCHAR2(200);
P_PAGE_INDEX NUMBER;
P_PAGE_SIZE NUMBER;
v_Return sys_refcursor;
type t_row is record (CAE_SEC_ID NUMBER,FM_SEC_CODE VARCHAR2(7),rownum number, v_total_count number);
v_rec t_row;
BEGIN
P_CAE_SEC_ID_N := NULL;
P_FM_SEC_CODE_C := NULL;
P_PAGE_INDEX := 0;
P_PAGE_SIZE := 25;
CAE_FOF_SECURITY_PKG.GET_LIST_FOF_SECURITY(
P_CAE_SEC_ID_N => P_CAE_SEC_ID_N,
P_FM_SEC_CODE_C => P_FM_SEC_CODE_C,
P_PAGE_INDEX => P_PAGE_INDEX,
P_PAGE_SIZE => P_PAGE_SIZE,
P_FOF_SEC_REFCUR => v_Return
);
-- Modify the code to output the variable
-- DBMS_OUTPUT.PUT_LINE('P_FOF_SEC_REFCUR = ');
loop
fetch v_Return into v_rec;
exit when v_Return%notfound;
DBMS_OUTPUT.PUT_LINE('sec_id = ' || v_rec.CAE_SEC_ID || 'sec code = ' ||v_rec.FM_SEC_CODE);
end loop;
END;

A comment to jarijira
Well I have had many issues with .html and .empty() methods for inputs o. If the id represents an input and not another type of html selector like
or use the .val() function to manipulate.
For example: this is the proper way to manipulate input values
<textarea class="form-control" id="someInput"></textarea>
$(document).ready(function () {
var newVal='test'
$('#someInput').val('') //clear input value
$('#someInput').val(newVal) //override w/ the new value
$('#someInput').val('test2)
newVal= $('#someInput').val(newVal) //get input value
}
For improper, but sometimes works For example: this is the proper way to manipulate input values
<textarea class="form-control" id="someInput"></textarea>
$(document).ready(function () {
var newVal='test'
$('#someInput').html('') //clear input value
$('#someInput').empty() //clear html inside of the id
$('#someInput').html(newVal) //override the html inside of text area w/ string could be '<div>test3</div>
really overriding with a string manipulates the value, but this is not the best practice as you do not put things besides strings or values inside of an input.
newVal= $('#someInput').val(newVal) //get input value
}
An issue that I had was I was using the $getJson method and I was indeed able to use .html calls to manipulate my inputs. However, whenever I had an error or fail on the getJSON I could no longer change my inputs using the .clear and .html calls. I could still return the .val(). After some experimentation and research I discovered that you should only use the .val() function to make changes to input fields.

CMake is actually pretty good for this. The key part was everyone on the Windows side has to remember to run CMake before loading in the solution, and everyone on our Mac side would have to remember to run it before make.
The hardest part was as a Windows developer making sure your structural changes were in the cmakelist.txt file and not in the solution or project files as those changes would probably get lost and even if not lost would not get transferred over to the Mac side who also needed them, and the Mac guys would need to remember not to modify the make file for the same reasons.
It just requires a little thought and patience, but there will be mistakes at first. But if you are using continuous integration on both sides then these will get shook out early, and people will eventually get in the habit.
C11 standard (n1570) §6.2.2.3 al1 p55 says :
A pointer to
void
may be converted to or from a pointer to any object type. A pointer to any object type may be converted to a pointer to void and back again; the result shall compare equal to the original pointer.
You can use this generic pointer to store a pointer to any object type, but you can't use usual arithmetic operations with it and you can't deference it.
Use the following code:
if(isset($_SERVER['HTTPS']) == 'on')
{
$self = $_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
?>
<script type='text/javascript'>
window.location.href = 'http://<?php echo $self ?>';

You may give a shot at using itoa. Another alternative is to use sprintf.
I downgraded via NuGet to MVC 4 and then upgraded again to 5.2.7 and it fixed this issue
From the JSON standard:
An object is an unordered collection of zero or more name/value pairs, where a name is a string and a value is a string, number, boolean, null, object, or array.
(emphasis mine).
So, no you can't guarantee the order.
I installed mavaen using sdkman because of which the other proposed solution didn't work, as they are applicable if the installation is done via Homebrew or as a standalone binary.
for my solution I did "which mvn" in the terminal which returned: "/Users/samkaz/.sdkman/candidates/maven/current/bin/mvn"
Then after opening the path in a finder and looking around the above directory I found settings.xml in the below folder. "/Users/samkaz/.sdkman/candidates/maven/3.6.3/conf"
You may try this
alist[0] = 2014
but if you are not sure about the position of 123 then you may try like this:
for idx, item in enumerate(alist):
if 123 in item:
alist[idx] = 2014
It denotes an rvalue reference. Rvalue references will only bind to temporary objects, unless explicitly generated otherwise. They are used to make objects much more efficient under certain circumstances, and to provide a facility known as perfect forwarding, which greatly simplifies template code.
In C++03, you can't distinguish between a copy of a non-mutable lvalue and an rvalue.
std::string s;
std::string another(s); // calls std::string(const std::string&);
std::string more(std::string(s)); // calls std::string(const std::string&);
In C++0x, this is not the case.
std::string s;
std::string another(s); // calls std::string(const std::string&);
std::string more(std::string(s)); // calls std::string(std::string&&);
Consider the implementation behind these constructors. In the first case, the string has to perform a copy to retain value semantics, which involves a new heap allocation. However, in the second case, we know in advance that the object which was passed in to our constructor is immediately due for destruction, and it doesn't have to remain untouched. We can effectively just swap the internal pointers and not perform any copying at all in this scenario, which is substantially more efficient. Move semantics benefit any class which has expensive or prohibited copying of internally referenced resources. Consider the case of std::unique_ptr
- now that our class can distinguish between temporaries and non-temporaries, we can make the move semantics work correctly so that the unique_ptr
cannot be copied but can be moved, which means that std::unique_ptr
can be legally stored in Standard containers, sorted, etc, whereas C++03's std::auto_ptr
cannot.
Now we consider the other use of rvalue references- perfect forwarding. Consider the question of binding a reference to a reference.
std::string s;
std::string& ref = s;
(std::string&)& anotherref = ref; // usually expressed via template
Can't recall what C++03 says about this, but in C++0x, the resultant type when dealing with rvalue references is critical. An rvalue reference to a type T, where T is a reference type, becomes a reference of type T.
(std::string&)&& ref // ref is std::string&
(const std::string&)&& ref // ref is const std::string&
(std::string&&)&& ref // ref is std::string&&
(const std::string&&)&& ref // ref is const std::string&&
Consider the simplest template function- min and max. In C++03 you have to overload for all four combinations of const and non-const manually. In C++0x it's just one overload. Combined with variadic templates, this enables perfect forwarding.
template<typename A, typename B> auto min(A&& aref, B&& bref) {
// for example, if you pass a const std::string& as first argument,
// then A becomes const std::string& and by extension, aref becomes
// const std::string&, completely maintaining it's type information.
if (std::forward<A>(aref) < std::forward<B>(bref))
return std::forward<A>(aref);
else
return std::forward<B>(bref);
}
I left off the return type deduction, because I can't recall how it's done offhand, but that min can accept any combination of lvalues, rvalues, const lvalues.
Lombok does not support that also indicated by making any @Value
annotated class final
(as you know by using @NonFinal
).
The only workaround I found is to declare all members final yourself and use the @Data
annotation instead. Those subclasses need to be annotated by @EqualsAndHashCode
and need an explicit all args constructor as Lombok doesn't know how to create one using the all args one of the super class:
@Data
public class A {
private final int x;
private final int y;
}
@Data
@EqualsAndHashCode(callSuper = true)
public class B extends A {
private final int z;
public B(int x, int y, int z) {
super(x, y);
this.z = z;
}
}
Especially the constructors of the subclasses make the solution a little untidy for superclasses with many members, sorry.
OpenGL is bundled with Visual Studio. You just need to install GLUT package (freeglut would be fine), which can be found in NuGet.
Open your solution, click TOOLS->NuGet Package Manager->Package Manager Console to open a NuGet console, type Install-Package freeglut
.

For VS 2013, use nupengl.core
package instead.

It's 2020 now. Use VCPKG.
You have to first obtain the Range object. Also, getCell() will not return the value of the cell but instead will return a Range object of the cell. So, use something on the lines of
function email() {
// Opens SS by its ID
var ss = SpreadsheetApp.openById("0AgJjDgtUl5KddE5rR01NSFcxYTRnUHBCQ0stTXNMenc");
// Get the name of this SS
var name = ss.getName(); // Not necessary
// Read cell 1,1 * Line below does't work *
// var data = Range.getCell(0, 0);
var sheet = ss.getSheetByName('Sheet1'); // or whatever is the name of the sheet
var range = sheet.getRange(1,1);
var data = range.getValue();
}
The hierarchy is Spreadsheet --> Sheet --> Range --> Cell.
'category_name'=>'this cat' also works but isn't printed in the WP docs
Got similar issue. Did following steps, issue resolved:
NOTE: For those wanting to use web workers and you need to avoid using document and nativeElement this will work.
I answered the same question here: https://stackoverflow.com/questions/47571144
Copy/Paste from the above link:
I had the same issue when I was making a drop-down menu and a confirmation dialog I wanted to dismiss them when clicking outside.
My final implementation works perfectly but requires some css3 animations and styling.
NOTE: i have not tested the below code, there may be some syntax problems that need to be ironed out, also the obvious adjustments for your own project!
What i did:
I made a separate fixed div with height 100%, width 100% and transform:scale(0), this is essentially the background, you can style it with background-color: rgba(0, 0, 0, 0.466); to make obvious the menu is open and the background is click-to-close. The menu gets a z-index higher than everything else, then the background div gets a z-index lower than the menu but also higher than everything else. Then the background has a click event that close the drop-down.
Here it is with your html code.
<div class="dropdownbackground" [ngClass]="{showbackground: qtydropdownOpened}" (click)="qtydropdownOpened = !qtydropdownOpened"><div>
<div class="zindex" [class.open]="qtydropdownOpened">
<button (click)="qtydropdownOpened = !qtydropdownOpened" type="button"
data-toggle="dropdown" aria-haspopup="true" [attr.aria-expanded]="qtydropdownOpened ? 'true': 'false' ">
{{selectedqty}}<span class="caret margin-left-1x "></span>
</button>
<div class="dropdown-wrp dropdown-menu">
<ul class="default-dropdown">
<li *ngFor="let quantity of quantities">
<a (click)="qtydropdownOpened = !qtydropdownOpened;setQuantity(quantity)">{{quantity }}</a>
</li>
</ul>
</div>
</div>
Here is the css3 which needs some simple animations.
/* make sure the menu/drop-down is in front of the background */
.zindex{
z-index: 3;
}
/* make background fill the whole page but sit behind the drop-down, then
scale it to 0 so its essentially gone from the page */
.dropdownbackground{
width: 100%;
height: 100%;
position: fixed;
z-index: 2;
transform: scale(0);
opacity: 0;
background-color: rgba(0, 0, 0, 0.466);
}
/* this is the class we add in the template when the drop down is opened
it has the animation rules set these how you like */
.showbackground{
animation: showBackGround 0.4s 1 forwards;
}
/* this animates the background to fill the page
if you don't want any thing visual you could use a transition instead */
@keyframes showBackGround {
1%{
transform: scale(1);
opacity: 0;
}
100% {
transform: scale(1);
opacity: 1;
}
}
If you aren't after anything visual you can just use a transition like this
.dropdownbackground{
width: 100%;
height: 100%;
position: fixed;
z-index: 2;
transform: scale(0);
opacity: 0;
transition all 0.1s;
}
.dropdownbackground.showbackground{
transform: scale(1);
}
This is the shortest I could find.

JavaScript only has a Number type that stores floating point values.
There is no int.
Edit:
If you want to format the number as a string with two digits after the decimal point use:
(4).toFixed(2)
1) When you use an initializer, for a struct or an array like that, the unspecified values are essentially default constructed. In the case of a primitive type like ints, that means they will be zeroed. Note that this applies recursively: you could have an array of structs containing arrays and if you specify just the first field of the first struct, then all the rest will be initialized with zeros and default constructors.
2) The compiler will probably generate initializer code that is at least as good as you could do by hand. I tend to prefer to let the compiler do the initialization for me, when possible.
For me it was that I could not cluster my zookeeper.

What about this :
substr($mystring.'/', 0, strpos($mystring, '/'))
Simply add a '/' to the end of mystring so you can be sure there is at least one ;)
The simplest and most fun way (imo) is glob
foreach (glob("*.*") as $filename) {
echo $filename."<br />";
}
But the standard way is to use the directory functions.
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
echo "filename: .".$file."<br />";
}
closedir($dh);
}
}
There are also the SPL DirectoryIterator methods. If you are interested
Yes, that is correct.
Not putting an expires

I had this problem with IE where the e.target.width would be undefined. The load event would fire but I couldn't get the dimensions of the image in IE (chrome + FF worked).
Turns out you need to look for e.currentTarget.naturalWidth & e.currentTarget.naturalHeight.
Once again, IE does things it's own (more complicated) way.
When a subscriber unsubscribes you are changing contents of the collection of Subscribers during enumeration.
There are several ways to fix this, one being changing the for loop to use an explicit .ToList()
:
public void NotifySubscribers(DataRecord sr)
{
foreach(Subscriber s in subscribers.Values.ToList())
{
^^^^^^^^^
...
You need a whole input match here.
System.out.println(test.matches("^(http|https|ftp)://.*$"));

System.out.println(test.matches("^(https?|ftp)://.*$"));

String[] args = {};
Method[] methods = clazz.getMethods();
for (Method m : methods) {
if (methodName.equals(m.getName())) {

}
You should be able to do this like (as you're using the query api):
Entrant.where("pincode").ne(null)
... which will result in a mongo query resembling:
entrants.find({ pincode: { $ne: null } })
A few links that might help:
It makes sure that the returned object (which is an RValue at that point) can't be modified. This makes sure the user can't do thinks like this:
myFunc() = Object(...);
That would work nicely if myFunc
returned by reference, but is almost certainly a bug when returned by value (and probably won't be caught by the compiler). Of course in C++11 with its rvalues this convention doesn't make as much sense as it did earlier, since a const object can't be moved from, so this can have pretty heavy effects on performance.
If the formula already exists in a cell you can fill it down as follows:

In order for the for the line labels to show you need to add plt.legend to your code. to build on the previous example above that also includes title, ylabel and xlabel:
import matplotlib.pyplot as plt
plt.plot(<X AXIS VALUES HERE>, <Y AXIS VALUES HERE>, 'line type', label='label here')
plt.plot(<X AXIS VALUES HERE>, <Y AXIS VALUES HERE>, 'line type', label='label here')
plt.title('title')
plt.ylabel('ylabel')
plt.xlabel('xlabel')
plt.legend()
plt.show()
If you want to avoid parsing the date and just want a timestamp in GMT, you could use:
final Date gmt = new Timestamp(System.currentTimeMillis()
- Calendar.getInstance().getTimeZone()
.getOffset(System.currentTimeMillis()));
There is an xml attribute for it:
android:buttonTint="yourcolor"
define a String variable using the JSP tags
<%!
String test = new String();
%>
then refer to that variable in your loop as
<c:forEach items="${myParams.items}" var="currentItem" varStatus="stat">
test+= whaterver_value
</c:forEach>
This solution works(Tested):
type nul | more /e /p
This converts isolated line feeds to carriage return line feed combination.
The C standard (actually C99, I'm not up to date) says:
Alphabetic escape sequences representing nongraphic characters in the execution character set are intended to produce actions on display devices as follows:
\b
(backspace) Moves the active position to the previous position on the current line. [...]
\t
(horizontal tab) Moves the active position to the next horizontal tabulation position on the current line. [...]
Both just move the active position, neither are supposed to write any character on or over another character. To overwrite with a space you could try: puts("foo\b \tbar");
but note that on some display devices - say a daisy wheel printer - the o
will show the transparent space.
Example from the guide:
\newcommand{\example}[2][YYY]{Mandatory arg: #2;
Optional arg: #1.}
This defines \example to be a command with two arguments,
referred to as #1 and #2 in the {<definition>}--nothing new so far.
But by adding a second optional argument to this \newcommand
(the [YYY]) the first argument (#1) of the newly defined
command \example is made optional with its default value being YYY.
Thus the usage of \example is either:
\example{BBB}
which prints:
Mandatory arg: BBB; Optional arg: YYY.
or:
\example[XXX]{AAA}
which prints:
Mandatory arg: AAA; Optional arg: XXX.

BIGHAP: A SIMPLE WORK AROUND FOR THIS ISSUE.
I ran into the same problem when working with SharePoint lists as the DataSource, and read the blogs above which were very helpful. I had made changes in both the DataSource and Data object names and query fields in Visual Studio and the query worked in visual Studio. I was able to deploy the report to SharePoint but when I tried to open it I received the same error.
I guessed that the issue was that I needed to redeploy both the DataSource and the DataSet to SharePoint so that that changes in the rendering tools were all synced.
I redeployed the DataSource, DataSet and the Report to sharePoint and it worked. As one of the blogs stated, although visual studio allowed the changes I made in the dataset and datasource, if you have not set visual studio to automatically redeploy datasource and dataset when you deploy the report(which can be dangerous, because this can affect other reports which share these objects) this error can occur.
So, of course the fix is that in this case you have to redeploy datasource, dataset and Report to resolve the issue.

In the recent Python version, subprocess
has a big change. It offers a brand-new class Popen
to handle os.popen1|2|3|4
.
The new subprocess.Popen()
import subprocess
subprocess.Popen('ls -la', shell=True)
Its arguments:
subprocess.Popen(args,
bufsize=0,
executable=None,
stdin=None, stdout=None, stderr=None,
preexec_fn=None, close_fds=False,
shell=False,
cwd=None, env=None,
universal_newlines=False,
startupinfo=None,
creationflags=0)
Simply put, the new Popen
includes all the features which were split into 4 separate old popen
.
The old popen
:
Method Arguments
popen stdout
popen2 stdin, stdout
popen3 stdin, stdout, stderr
popen4 stdin, stdout and stderr

I've incurred in a weird behaviour using [].
We have Model "classes" with fields initialised to some value. E.g.:
require([
"dojo/_base/declare",
"dijit/_WidgetBase",
], function(declare, parser, ready, _WidgetBase){
declare("MyWidget", [_WidgetBase], {
field1: [],
field2: "",
function1: function(),
function2: function()
});
});
I found that when the fields are initialised with []
then it would be shared by all Model objects. Making changes to one affects all others.
This doesn't happen initialising them with new Array()
. Same for the initialisation of Objects ({}
vs new Object()
)
TBH I am not sure if its a problem with the framework we were using (Dojo)
$('#my_select option:selected').attr('id');
There exists now a dedicated bash script plugin called "Bash editor". It's available at eclipse market place:
You can find it at https://marketplace.eclipse.org/content/bash-editor or by marketplace client when searching for "bash".
The plugin does also provide a debugger. Inisde official Bash Editor
YouTube playlist you can find some tutorials about usage etc.
PS: I am the author of the mentioned plugin.
It looks like findElements()
only returns quickly if it finds at least one element. Otherwise it waits for the implicit wait timeout, before returning zero elements - just like findElement()
.
To keep the speed of the test good, this example temporarily shortens the implicit wait, while waiting for the element to disappear:
static final int TIMEOUT = 10;
public void checkGone(String id) {
FluentWait<WebDriver> wait = new WebDriverWait(driver, TIMEOUT)
.ignoring(StaleElementReferenceException.class);
driver.manage().timeouts().implicitlyWait(1, TimeUnit.SECONDS);
try {
wait.until(ExpectedConditions.numberOfElementsToBe(By.id(id), 0));
} finally {
resetTimeout();
}
}
void resetTimeout() {
driver.manage().timeouts().implicitlyWait(TIMEOUT, TimeUnit.SECONDS);
}
Still looking for a way to avoid the timeout completely though...
Another option when you need a simple css style of one or two properties:
View:
<tr ng-repeat="element in collection">
[...amazing code...]
<td ng-style="{'background-color': getTrColor(element.myvar)}">
{{ element.myvar }}
</td>
[...more amazing code...]
</tr>
Controller:
$scope.getTrColor = function (colorIndex) {
switch(colorIndex){
case 0: return 'red';
case 1: return 'green';
default: return 'yellow';
}
};
Some times even I type Ctrl+Alt+L is not working in XML, so found this way to make it work.
Go to Settings --> Editor --> Code Style --> Select Default --> Ok.

DateTime date_temp_to = DateTime.Parse(to.Value); //to.value" is input by user (dd/MM/yyyy)
string date_from = date_temp_from.ToString("yyyy/MM/dd HH:mm");
string date_to = date_temp_to.ToString("yyyy/MM/dd HH:mm");

These answers didn't work for me. I had to use the following:
import subprocess
p = subprocess.Popen(["pwd"], stdout=subprocess.PIPE)
out = p.stdout.read()
print out
Or as a function (using shell=True was required for me on Python 2.6.7 and check_output was not added until 2.7, making it unusable here):
def system_call(command):
p = subprocess.Popen([command], stdout=subprocess.PIPE, shell=True)
return p.stdout.read()
In my case I have got the error when trying to create a databae on a new drive. To overcome the problem I created a new folder in that drive and set the user properties Security to full control on it(It may be sufficient to set Modify ). Conclusion: SET the Drive/Folder Properties Security for users to "Modify".
Similar to brianegge's awk solution, here is the Perl equivalent:
ps | egrep 11383 | perl -lane 'print $F[3]'
-a
enables autosplit mode, which populates the @F
array with the column data.
Use -F,
if your data is comma-delimited, rather than space-delimited.
Field 3 is printed since Perl starts counting from 0 rather than 1
I can think of three options:
RFC 2217 covers a com port to TCP/IP standard that allows a client on one system to emulate a serial port to the local programs, while transparently sending and receiving data and control signals to a server on another system which actually has the serial port. Here's a high-level overview.
What you would do is find or implement a client com port driver that would implement the client side of the system on your PC - appearing to be a real serial port but in reality shuttling everything to a server. You might be able to get this driver for free from Digi, Lantronix, etc in support of their real standalone serial port servers.
You would then implement the server side of the connection locally in another program - allowing the client to connect and issuing the data and control commands as needed.
It's probably non trivial, but the RFC is out there, and you might be able to find an open source project that implements one or both sides of the connection.
Alternately, the serial port driver source for Linux is readily available. Take that, gut the hardware control pieces, and have that one driver run two /dev/ttySx ports, as a simple loopback. Then connect your real program to the ttyS2 and your simulator to the other ttySx.
But the easiest thing to do right now? Spend $40 on two serial port USB devices, wire them together (null modem) and actually have two real serial ports - one for the program you're testing, one for your simulator.

It will work perfectly displaying all the outputs.
If you assume what you are sorting are just numbers and only their values identify/distinguish them (e.g. elements with same value are identicle), then the stability-issue of sorting is meaningless.
However, objects with same priority in sorting may be distinct, and sometime their relative order is meaningful information. In this case, unstable sort generates problems.
For example, you have a list of data which contains the time cost [T] of all players to clean a maze with Level [L] in a game. Suppose we need to rank the players by how fast they clean the maze. However, an additional rule applies: players who clean the maze with higher-level always have a higher rank, no matter how long the time cost is.
Of course you might try to map the paired value [T,L] to a real number [R] with some algorithm which follows the rules and then rank all players with [R] value.
However, if stable sorting is feasible, then you may simply sort the entire list by [T] (Faster players first) and then by [L]. In this case, the relative order of players (by time cost) will not be changed after you grouped them by level of maze they cleaned.
PS: of course the approach to sort twice is not the best solution to the particular problem but to explain the question of poster it should be enough.

You can use the concept of multiple queries in the FROM keyword. Let me show you one example:
SELECT DISTINCT e.id,e.name,d.name,lap.lappy LAPTOP_MAKE,c_loc.cnty COUNTY
FROM (
SELECT c.id cnty,l.name
FROM county c, location l
WHERE c.id=l.county_id AND l.end_Date IS NOT NULL
) c_loc, emp e
INNER JOIN dept d ON e.deptno =d.id
LEFT JOIN
(
SELECT l.id lappy, c.name cmpy
FROM laptop l, company c
WHERE l.make = c.name
) lap ON e.cmpy_id=lap.cmpy
You can use as many tables as you want to. Use outer joins and union where ever it's necessary, even inside table subqueries.
That's a very easy method to involve as many as tables and fields.
This is not supported behavior of the MVC System. If you want to execute an action of another controller you just redirect the user to the page you want (i.e. the controller function that consumes the url).
If you want common functionality, you should build a library to be used in the two different controllers.
I can only assume you want to build up your site a bit modular. (I.e. re-use the output of one controller method in other controller methods.) There's some plugins / extensions for CI that help you build like that. However, the simplest way is to use a library to build up common "controls" (i.e. load the model, render the view into a string). Then you can return that string and pass it along to the other controller's view.
You can load into a string by adding true
at the end of the view call:
$string_view = $this->load->view('someview', array('data'=>'stuff'), true);
What about this?
>>> first_element, last_element = some_list[0], some_list[-1]
You need to use Store.getState()
to get current state of your Store.

The view controller must be a child of some UINavigationController for the .title
property to take effect. If the UINavigationBar is simply a view, you need to push a navigation item containing the title, or modify the last navigation item:
UINavigationItem* item = [[UINavigationItem alloc] initWithTitle:@"title text"];
...
[bar pushNavigationItem:item animated:YES];
[item release];
or
bar.topItem.title = @"title text";
I understood the question as "How do I match a word but exclude another", for which one solution is two greps in series: First grep finding the wanted "word1", second grep excluding "word2":
grep "word1" | grep -v "word2"
In my case: I need to differentiate between "plot" and "#plot" which grep's "word" option won't do ("#" not being a alphanumerical).
Hope this helps.
The right answer is, that some of your jar files does not compile. You should go into your build.gradle file in your project, and look in your dependencies.
If you're just importing some jar files, you could try to remove them and add them one at a time. This will help you determine which one of them causes the error.
In my case, I did just that, and when I was importing the last one, the app compiled. So I think the real problem was that I was importing too many at once. But now it all works.
You could also use the RANK function
=RANK(C2,$C$2:$C$7,0)
It would return data like your example:
| A | B | C
1 | name | position | points
2 | person1 | 1 | 10
3 | person2 | 2 | 9
4 | person3 | 2 | 9
5 | person4 | 2 | 9
6 | person5 | 5 | 8
7 | person6 | 6 | 7
The 'Points' column needs to be sorted into descending order.
Your xpath is just a little off:
count(//Property/long[text()=$parPropId])
Edit: Cerebrus quite rightly points out that the code in your OP (using the implicit value of a node) is absolutely fine for your purposes. In fact, since it's quite likely you want to work with the "Property" node rather than the "long" node, it's probably superior to ask for //Property[long=$parPropId]
than the text() xpath, though you could make a case for the latter on readability grounds.
What can I say, I'm a bit tired today :)
Ranjit's code caused the same error message as reported by Tin, but worked after updating Cn.open with the ODBC driver I'm running. Check the Drivers tab in the ODBC Data Source Administrator. Mine said "MySQL ODBC 5.3 Unicode Driver" so I updated accordingly.
Small hint which other people didn't talk about: git doesn't record changes if you add empty folders in your project folder. That's it, I was adding empty folders with random names to check wether it was recording changes, it wasn't. But it started to do it as soon as I began adding files in them. Cheers.
It was giving 415 Http response Code as error,

Another interesting variant question can be:
How would you make "12345"
as "12 23 34 45"
without using another string?
Will following do?
for(int i=0; i < a.size()-1; ++i)
{
//b = a.substr(i, 2);
c = atoi((a.substr(i, 2)).c_str());
cout << c << " ";
}
Surprised I haven't seen this yet, so without further ado, here is:
it depends if your div is in position: absolute / fixed or relative / static
for position: absolute & fixed
<div style="position: absolute; /*or fixed*/;
width: 50%;
height: 300px;
left: 50%;
top:100px;
margin: 0 0 0 -25%">blblablbalba</div>
The trick here is to have a negative margin half the width of the object
for position: relative & static
<div style="position: relative; /*or static*/;
width: 50%;
height: 300px;
margin: 0 auto">blblablbalba</div>
for both techniques, it is imperative to set the width.
Unless you unpack them, assets remain inside the apk. Accordingly, there isn't a path you can feed into a File. The path you've given in your question will work with/in a WebView, but I think that's a special case for WebView.
You'll need to unpack the file or use it directly.
If you have a Context, you can use context.getAssets().open("myfoldername/myfilename");
to open an InputStream on the file. With the InputStream you can use it directly, or write it out somewhere (after which you can use it with File).
You can use this method also it will act like that
thadari=[1,2,3,4,5,6]
#Front Two(Left)
print(thadari[:2])
[1,2]
#Last Two(Right)# edited
print(thadari[-2:])
[5,6]
#mid
mid = len(thadari) //2
lefthalf = thadari[:mid]
[1,2,3]
righthalf = thadari[mid:]
[4,5,6]
Hope it will help

@Martin Devillers solution works fine. For completeness, providing the steps below:
src/main/resource
In pom file, add both wsdlDirectory and wsdlLocation(don't miss / at the beginning of wsdlLocation), like below. While wsdlDirectory is used to generate code and wsdlLocation is used at runtime to create dynamic proxy.
<wsdlDirectory>src/main/resources/mydir</wsdlDirectory>
<wsdlLocation>/mydir/my.wsdl</wsdlLocation>
Then in your java code(with no-arg constructor):
MyPort myPort = new MyPortService().getMyPort();

Although it is too late to answer this question. Here are my answer on the same.
If you are using CodeIgniter then you can use inbuilt methods defined in query_builder class.
$this->db->insert_batch()
Generates an insert string based on the data you supply, and runs the query. You can either pass an array or an object to the function. Here is an example using an array:
$data = array(
array(
'title' => 'My title',
'name' => 'My Name',
'date' => 'My date'
),
array(
'title' => 'Another title',
'name' => 'Another Name',
'date' => 'Another date'
)
);
$this->db->insert_batch('mytable', $data);
// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date'), ('Another title', 'Another name', 'Another date')
The first parameter will contain the table name, the second is an associative array of values.
You can find more details about query_builder here
pipe it through awk '{print substr($0,42)}'
where 42 is one more than the number of characters to drop. For example:
$ echo abcde| awk '{print substr($0,2)}'
bcde
$
No requires converting the Task to int. Simply Use The Task Result.
int taskResult = AccessTheWebAndDouble().Result;
public async Task<int> AccessTheWebAndDouble()
{
int task = AccessTheWeb();
return task;
}
It will return the value if available otherwise it return 0.
You can replace 0
with NA
only in numeric fields (i.e. excluding things like factors), but it works on a column-by-column basis:
col[col == 0 & is.numeric(col)] <- NA
With a function, you can apply this to your whole data frame:
changetoNA <- function(colnum,df) {
col <- df[,colnum]
if (is.numeric(col)) { #edit: verifying column is numeric
col[col == -1 & is.numeric(col)] <- NA
}
return(col)
}
df <- data.frame(sapply(1:5, changetoNA, df))
Although you could replace the 1:5
with the number of columns in your data frame, or with 1:ncol(df)
.
You could do this:
Map<String, List<Student>> map = new HashMap<String, List<Student>>();
List<Student> studlist = new ArrayList<Student>();
studlist.add(new Student("1726", "John", "New York"));
map.put("New York", studlist);
the keys will be locations and the values list of students. So later you can get a group of students just by using:
studlist = map.get("New York");
It seems the closest is:

}

The __del__
method, it will be called when the object is garbage collected. Note that it isn't necessarily guaranteed to be called though. The following code by itself won't necessarily do it:
del obj
The reason being that del
just decrements the reference count by one. If something else has a reference to the object, __del__
won't get called.
There are a few caveats to using __del__
though. Generally, they usually just aren't very useful. It sounds to me more like you want to use a close method or maybe a with statement.
See the python documentation on __del__
methods.
One other thing to note: __del__
methods can inhibit garbage collection if overused. In particular, a circular reference that has more than one object with a __del__
method won't get garbage collected. This is because the garbage collector doesn't know which one to call first. See the documentation on the gc module for more info.
Can't you just use a Definite Assignment Assertion? (See https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-7.html#definite-assignment-assertions)
i.e. declaring the property as makes!: any[];
The ! assures typescript that there definitely will be a value at runtime.
Sorry I haven't tried this in angular but it worked great for me when I was having the exact same problem in React.
Try this ..

You've to set the JAVA SDK and appropriate language level in the project settings. Click to enlarge.
7zip
(7za) can be used for adding/updating files/directories nicely:
Example:
Replacing (regardless of file date) the MANIFEST.MF
file in a JAR file. The /source/META-INF
directory contains the MANIFEST.MF
file that you want to put into the jar
(zip):
7za a /tmp/file.jar /source/META-INF/
Only update (does not replace the target if the source is older)
7za u /tmp/file.jar /source/META-INF/
This is a great topic on the issue, however I found that one important detail (which was essential at least in my case) that was not posted here or anywhere else (I apologize if I just missed it) was that the P3P line must be passed in header of EVERY file sent from the 3rd party server, even files not setting or using the cookies such as Javascript files or images. Otherwise the cookies will be blocked. I have more on this in a post here: http://posheika.net/?p=110
You can use selectedIndex
to retrieve the current selected option
:
el = document.getElementById('elemId')
selectedText = el.options[el.selectedIndex].text
And of course for auto indentation and formatting, following the language you're using, you can see which good extensions do the good job, and which formatters to install or which parameters settings to enable or set for each language and its available tools. Just make sure to read well the documentation of the extension, to install and set all what it need.
Up to now the indentation problem bothers me with Python when copy pasting a block of code. If that's the case, here is how you solve that: Visual Studio Code indentation for Python
Use DATALENGTH method, for example:
SELECT length = DATALENGTH(myField)
FROM myTABLE
Quote from this link-
If you want to find and print the top 10 largest files names (not directories) in a particular directory and its sub directories
$ find . -printf '%s %p\n'|sort -nr|head
To restrict the search to the present directory use "-maxdepth 1" with find.
$ find . -maxdepth 1 -printf '%s %p\n'|sort -nr|head
And to print the top 10 largest "files and directories":
$ du -a . | sort -nr | head
** Use "head -n X" instead of the only "head" above to print the top X largest files (in all the above examples)
The history limit is a pane attribute that is fixed at the time of pane creation and cannot be changed for existing panes. The value is taken from the history-limit
session option (the default value is 2000).
To create a pane with a different value you will need to set the appropriate history-limit
option before creating the pane.
To establish a different default, you can put a line like the following in your .tmux.conf
file:
set-option -g history-limit 3000
Note: Be careful setting a very large default value, it can easily consume lots of RAM if you create many panes.
For a new pane (or the initial pane in a new window) in an existing session, you can set that session’s history-limit
. You might use a command like this (from a shell):
tmux set-option history-limit 5000 \; new-window
For (the initial pane of the initial window in) a new session you will need to set the “global” history-limit
before creating the session:
tmux set-option -g history-limit 5000 \; new-session
Note: If you do not re-set the history-limit
value, then the new value will be also used for other panes/windows/sessions created in the future; there is currently no direct way to create a single new pane/window/session with its own specific limit without (at least temporarily) changing history-limit
(though show-option
(especially in 1.7 and later) can help with retrieving the current value so that you restore it later).
Regardless of your situation, heres a working demo that creates markers on the map based on an array of addresses.
Javascript code embedded aswell:
$(document).ready(function () {
var map;
var elevator;
var myOptions = {
zoom: 1,
center: new google.maps.LatLng(0, 0),
mapTypeId: 'terrain'
};
map = new google.maps.Map($('#map_canvas')[0], myOptions);
var addresses = ['Norway', 'Africa', 'Asia','North America','South America'];
for (var x = 0; x < addresses.length; x++) {
$.getJSON('http://maps.googleapis.com/maps/api/geocode/json?address='+addresses[x]+'&sensor=false', null, function (data) {
var p = data.results[0].geometry.location
var latlng = new google.maps.LatLng(p.lat, p.lng);
new google.maps.Marker({
position: latlng,
map: map
});
});
}
});
Do not forget to clear the cache after updating the external_url
param in /etc/gitlab/gitlab.rb
, otherwise your existing project clone URLs will still be showing your old host name.
A simple 3 step process to change the hostname is as follows

param in /etc/gitlab/gitlab.rb

If you set up a click binding in Knockout the event is passed as the second parameter. You can use the event to obtain the element that the click occurred on and perform whatever action you want.
Here is a fiddle that demonstrates: http://jsfiddle.net/jearles/xSKyR/
Alternatively, you could create your own custom binding, which will receive the element it is bound to as the first parameter. On init you could attach your own click event handler to do any actions you wish.

def closest(list, Number):
aux = []

This code will give you the index of the closest number of Number in the list.
The solution given by KennyTM is the best overall, but in the cases you cannot use it (like brython), this function will do the work
fopen()
will open a resource in the same directory as the file executing the command. In other words, if you're just running the file ~/test.php, your script will create ~/myText.txt.
This can get a little confusing if you're using any URL rewriting (such as in an MVC framework) as it will likely create the new file in whatever the directory contains the root index.php file.
Also, you must have correct permissions set and may want to test before writing to the file. The following would help you debug:
$fp = fopen("myText.txt","wb");
if( $fp == false ){
//do debugging or logging here
}else{
fwrite($fp,$content);
fclose($fp);
}
See my answer to the question Importing modules from parent folder for related information, including why my answer doesn't use the unreliable __file__
variable. This simple solution should be cross-compatible with different operating systems as the modules os
and inspect
come as part of Python.
First, you need to import parts of the inspect and os modules.
from inspect import getsourcefile
from os.path import abspath
Next, use the following line anywhere else it's needed in your Python code:
abspath(getsourcefile(lambda:0))
From the built-in module os
(description below), the abspath
tool is imported.
OS routines for Mac, NT, or Posix depending on what system we're on.
Then getsourcefile
(description below) is imported from the built-in module inspect
.
Get useful information from live Python objects.
abspath(path)
returns the absolute/full version of a file pathgetsourcefile(lambda:0)
somehow gets the internal source file of the lambda function object, so returns '<pyshell#nn>'
in the Python shell or returns the file path of the Python code currently being executed.Using abspath
on the result of getsourcefile(lambda:0)
should make sure that the file path generated is the full file path of the Python file.
This explained solution was originally based on code from the answer at How do I get the path of the current executed file in Python?.

The client has a pre-seeded store of SSL certificate authorities' public keys. There must be a chain of trust from the certificate for the server up through intermediate authorities up to one of the so-called "root" certificates in order for the server to be trusted.
You can examine and/or alter the list of trusted authorities. Often you do this to add a certificate for a local authority that you know you trust - like the company you work for or the school you attend or what not.
The pre-seeded list can vary depending on which client you use. The big SSL certificate vendors insure that their root certs are in all the major browsers ($$$).
Monkey-in-the-middle attacks are "impossible" unless the attacker has the private key of a trusted root certificate. Since the corresponding certificates are widely deployed, the exposure of such a private key would have serious implications for the security of eCommerce generally. Because of that, those private keys are very, very closely guarded.
If you want to avoid fencepost errors and avoid moving and deleting items in an array, here is a somewhat verbose solution that uses List
:
import java.util.ArrayList;
import java.util.List;
public class RemoveNullValue {
public static void main( String args[] ) {
String[] firstArray = {"test1", "", "test2", "test4", "", null};
List<String> list = new ArrayList<String>();
for(String s : firstArray) {
if(s != null && s.length() > 0) {
list.add(s);
}
}
firstArray = list.toArray(new String[list.size()]);
}
}
Added null
to show the difference between an empty String instance (""
) and null
.
Since this answer is around 4.5 years old, I'm adding a Java 8 example:
import java.util.Arrays;
import java.util.stream.Collectors;
public class RemoveNullValue {
public static void main( String args[] ) {
String[] firstArray = {"test1", "", "test2", "test4", "", null};
firstArray = Arrays.stream(firstArray)
.filter(s -> (s != null && s.length() > 0))
.toArray(String[]::new);
}
}
You just need to clear the table and call the function that generates the filling of the table.
ButtonRefresh.setOnAction((event) -> { tacheTable.getItems().clear(); PopulateTable(); });
if you want to override that onConfigurationChanged method and still want it to do the basic stuff then consider using super.onConfigyrationChanged() as the first statement in the overriden method.
Try wrapping your dates in single quotes, like this:

selector is used for applying multiple alternate drawables for different status of the view, so in this case, there is no need for selector
instead use shape
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#ffffff" />
<stroke android:width="1dip" android:color="#ff9900" />

int year = 2012;
int month = 12;
int day = 24;
int hour = 0;
int min = 0;
int second = 23;
DateTime dt = new DateTime(year, month, day, hour, min, second);
You could also do something like:
String str = "a + b - c * d / e < f > g >= h <= i == j";
String[] arr = str.split("(?<=\\G(\\w+(?!\\w+)|==|<=|>=|\\+|/|\\*|-|(<|>)(?!=)))\\s*");
It handles white spaces and words of variable length and produces the array:
[a, +, b, -, c, *, d, /, e, <, f, >, g, >=, h, <=, i, ==, j]
Another application for XOR
is in circuits. It is used to sum bits.
When you look at a truth table:
x | y | x^y
---|---|-----
0 | 0 | 0 // 0 plus 0 = 0
0 | 1 | 1 // 0 plus 1 = 1
1 | 0 | 1 // 1 plus 0 = 1
1 | 1 | 0 // 1 plus 1 = 0 ; binary math with 1 bit
You can notice that the result of XOR
is x added with y, without keeping track of the carry bit, the carry bit is obtained from the AND
between x and y.
x^y // is actually ~xy + ~yx
// Which is the (negated x ANDed with y) OR ( negated y ANDed with x ).

The thread will block, but the process is still alive.
In a single threaded application, this means everything is blocked while you sleep. In a multithreaded application, only the thread you explicitly 'sleep' will block and the other threads still run within the process.
Set up a virtualenv:
% curl -kLso /tmp/get-pip.py https://bootstrap.pypa.io/get-pip.py
% sudo python /tmp/get-pip.py
These commands install pip into the global site-packages directory.
% sudo pip install virtualenv
and ditto for virtualenv:
% mkdir -p ~/.virtualenvs
I like my virtualenvs under one tree in my home directory called .virtualenvs
% virtualenv ~/.virtualenvs/lxmltest
Creates a virtualenv.
% . ~/.virtualenvs/lxmltest/bin/activate
Removes the need to specify the full path to pip/python in this virtualenv.
% pip install lxml
Alternatively execute ~/.virtualenvs/lxmltest/bin/pip install lxml
if you chose not to follow the previous step. Note, I'm not sure how far along you are, so some of these steps can be safely skipped. Of course, if you mess something up, you can always rm -Rf ~/.virtualenvs/lxmltest
and start again from a new virtualenv.

There is no way to set maxHeight. But you can set the Height.
To do that you will need to discovery the height of each item of you scrollView. After that just set your scrollView height to numberOfItens * heightOfItem.
To discovery the height of an item do that:
View item = adapter.getView(0, null, scrollView);
item.measure(0, 0);
int heightOfItem = item.getMeasuredHeight();
To set the height do that:
// if the scrollView already has a layoutParams:
scrollView.getLayoutParams().height = heightOfItem * numberOfItens;
// or
// if the layoutParams is null, then create a new one.
scrollView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, heightOfItem * numberOfItens));
Use the substring method of the String class :
String removeCurrency=amount.getText().toString().substring(3);
The first option is simply to hide an error with disabling it by configuring errorOnUnhandledRejections
in $qProvider configuration as suggested Cengkuru Michael
BUT this will only switch off logging. The error itself will remain
The better solution in this case will be - handling a rejection with .catch(fn)
method:
resource.get().$promise
.then(function (response) {})
.catch(function (err) {});

Use --format
option to get only the IP address instead whole container info:

So easy we can get the String from files by method: getText();
public class Main {
static int countOfWords(String str) {
if (str.equals("") || str == null) {
return 0;
}else{
int numberWords = 0;
for (char c : str.toCharArray()) {
if (c == ' ') {
numberWords++;
}
}
return ++numberWordss;
}
}
}
It's obvious why you'd want to disable this: To force IntelliJ to include each and every import individually. It makes it easier for people to figure out exactly where classes you're using come from.
Click on the Settings "wrench" icon on the toolbar, open "Imports" under "Code Style", and check the "Use single class import" selection. You can also completely remove entries under "Packages to use import with *
", or specify a threshold value that only uses the "*
" when the individual classes from a package exceeds that threshold.
Update: in IDEA 13 "Use single class import" does not prevent wildcard imports. The solution is to go to Preferences
(? + , on macOS / Ctrl + Alt + S on Windows and Linux) > Editor > Code Style > Java > Imports tab
set Class count to use import with '*'
and Names count to use static import with '*'
to a higher value. Any value over 99 seems to work fine.
This hasn't solved my problem too, so I changed the parameters slightly.
This code worked for me:
var dataValue = "{ name: 'person', isGoing: 'true', returnAddress: 'returnEmail' }";
$.ajax({
type: "POST",
url: "Default.aspx/OnSubmit",
data: dataValue,
contentType: 'application/json; charset=utf-8',
dataType: 'json',
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
},
success: function (result) {
alert("We returned: " + result.d);
}
});
alternative solution with awk and double parenthesis:
FILENAME=file.txt
SIZE=$(du -sb $FILENAME | awk '{ print $1 }')
if ((SIZE<90000)) ; then
echo "less";
else
echo "not less";

The disabled
attribute is not global and is only allowed on form controls. What you could do is set a custom data attribute (perhaps data-disabled
) and check for that attribute when you handle the click event.
Insert the following into decompile.jar.sh
# Usage: decompile.jar.sh some.jar [-d]
# clean target folders
function clean_target {
rm -rf $unjar $src $jad_log
}
# clean all debug stuff
function clean_stuff {
rm -rf $unjar $jad_log
}
# the main function
function work {
jar=$1
unjar=`basename $jar.unjar`
src=`basename $jar.src`
jad_log=jad.log
clean_target
unzip -q $jar -d $unjar
jad -d $src -ff -r -lnc -o -s java $unjar/**/*.class > $jad_log 2>&1
if [ ! $debug ]; then
clean_stuff
fi
if [ -d $src ]
then
echo "$jar has been decompiled to $src"
else
echo "Got some problems check output or run in debug mode"
fi
}
function usage {
echo "This script extract and decompile JAR file"
echo "Usage: $0 some.jar [-d]"
echo " where: some.jar is the target to decompile"
echo " use -d for debug mode"
}
# check params
if [ -n "$1" ]
then
if [ "$2" == "-d" ]; then
debug=true
set -x
fi
work $1
else
usage
fi
Ready to use, just type dj your.jar
and you will get your.jar.src
folder with sources. Use -d
option for debug mode.
