Build system independent method
make SHELL='sh -x'
is another option. Sample Makefile
:
a:
@echo a
Output:
+ echo a
a
This sets the special SHELL
variable for make
, and -x
tells sh
to print the expanded line before executing it.
One advantage over -n
is that is actually runs the commands. I have found that for some projects (e.g. Linux kernel) that -n
may stop running much earlier than usual probably because of dependency problems.
One downside of this method is that you have to ensure that the shell that will be used is sh
, which is the default one used by Make as they are POSIX, but could be changed with the SHELL
make variable.
Doing sh -v
would be cool as well, but Dash 0.5.7 (Ubuntu 14.04 sh
) ignores for -c
commands (which seems to be how make
uses it) so it doesn't do anything.
make -p
will also interest you, which prints the values of set variables.
CMake generated Makefiles always support VERBOSE=1
As in:
mkdir build
cd build
cmake ..
make VERBOSE=1
Dedicated question at: Using CMake with GNU Make: How can I see the exact commands?
I had a similar problem to this one. It got solved by deleting the java:comp/env/
prefix and using jdbc/myDataSource
in the context lookup. Just as someone pointed out in the comments.

Twitter's naming is just too confusing.
I know that this already has plenty of answers and is a rather old question. But I just came up with this neat one-liner:
JSON.parse(JSON.stringify(raw, ['key', 'value', 'item1', 'item3']))
That returns another object with just the whitelisted attributes. Note that the key
and value
is included in the list.
You can use termcolor for this:
sudo pip install termcolor
To print a colored bold:
from termcolor import colored
print(colored('Hello', 'green', attrs=['bold']))
For more information, see termcolor on PyPi.
simple-colors is another package with similar syntax:
from simple_colors import *
print(green('Hello', ['bold'])
The equivalent in colorama may be Style.BRIGHT
.
Many of the other answers will lead to errors/warnings. This approach is relatively fool proof although you may still need git branch -D branch_to_delete
if it's not fully merged into some_other_branch
, for example.
git checkout some_other_branch
git push origin :branch_to_delete
git branch -d branch_to_delete
Remote pruning isn't needed if you deleted the remote branch. It's only used to get the most up-to-date remotes available on a repository you're tracking. I've observed git fetch
will add remotes, not remove them. Here's an example of when git remote prune origin
will actually do something:
User A does the steps above. User B would run the following commands to see the most up-to-date remote branches:
git fetch
git remote prune origin
git branch -r
For anyone still coming to this post, the other option is to simply omit the parentheses:
Sub SomeOtherSub(Stattyp As String)
'Daty and the other variables are defined here
CatSubProduktAreakum Stattyp, Daty + UBound(SubCategories) + 2
End Sub
The Call
keywords is only really in VBA for backwards compatibilty and isn't actually required.
If however, you decide to use the Call
keyword, then you have to change your syntax to suit.
'// With Call
Call Foo(Bar)
'// Without Call
Foo Bar
Both will do exactly the same thing.
That being said, there may be instances to watch out for where using parentheses unnecessarily will cause things to be evaluated where you didn't intend them to be (as parentheses do this in VBA) so with that in mind the better option is probably to omit the Call
keyword and the parentheses
In my scenario, I've got an MVC app and WebAPI in one solution, and I'm using local IIS (not express).
I also set up the sites in IIS as real domains, and edited my host file so that I can type in the real domain and everything works. I also noticed 2 things:
The MVC code debugging was working perfectly.
Attaching to process worked perfectly too. Just when I was debugging it didn't hit the breakpoint in my API.
This was the solution for me:
Right click webapi project > properties > Web > Project URL
By default it points to localhost, but since I set up the site in IIS, I forgot to change the URL to the website domain (i.e. instead of locahost, it should say http://{domain-name}/).
Try SuperPuTTY. It is similar to puttycm.
The sqlite answer is
update TABLE set mydatetime = datetime('now');
in case someone else was looking for it.
I've found that using this null comparison works well:
if (Combobox.SelectedItem != null){
//Do something
}
else{
MessageBox.show("Please select a item");
}
This will only accept the selected item and no other value which may have been entered manually by the user which could cause validation issues.
It's incorrect, but you can try this instead:
select
a.x,
( select b.y from b where b.v = a.v) as by,
( select b.z from b where b.v = a.v) as bz
from a
you can also use subquery in join
select
a.x,
b.y,
b.z
from a
left join (select y,z from b where ... ) b on b.v = a.v
or
select
a.x,
b.y,
b.z
from a
left join b on b.v = a.v
Using bash regex capabilities:
re="^([^-]+)-(.*)$"
[[ "ABCDE-123456" =~ $re ]] && var1="${BASH_REMATCH[1]}" && var2="${BASH_REMATCH[2]}"
echo $var1
echo $var2
OUTPUT
ABCDE

First shift the column:
df['gdp'] = df['gdp'].shift(-1)
Second remove the last row which contains an NaN Cell:
df = df[:-1]
Third reset the index:
df = df.reset_index(drop=True)
From the Intel's manual - Instruction Set Reference, the JE

for rel 16/32) share opcodes.
JE

they both check for the ZF

rel8 and JZ
rel8 ZF
usage, but basically they are the same.
Here is an extract from the manual's pages 464, 465 and 467.

Create a Pivot Table. It has these features and many more.
If you are dead-set on doing this yourself then you could add shapes to the worksheet and use VBA to hide and unhide rows and columns on clicking the shapes.
Ultimately you want to review the datetime documentation and become familiar with the formatting variables, but here are some examples to get you started:
import datetime
print('Timestamp: {:%Y-%m-%d %H:%M:%S}'.format(datetime.datetime.now()))
print('Timestamp: {:%Y-%b-%d %H:%M:%S}'.format(datetime.datetime.now()))
print('Date now: %s' % datetime.datetime.now())
print('Date today: %s' % datetime.date.today())
today = datetime.date.today()
print("Today's date is {:%b, %d %Y}".format(today))
schedule = '{:%b, %d %Y}'.format(today) + ' - 6 PM to 10 PM Pacific'
schedule2 = '{:%B, %d %Y}'.format(today) + ' - 1 PM to 6 PM Central'
print('Maintenance: %s' % schedule)
print('Maintenance: %s' % schedule2)
The output:
Timestamp: 2014-10-18 21:31:12
Timestamp: 2014-Oct-18 21:31:12
Date now: 2014-10-18 21:31:12.318340
Date today: 2014-10-18

mail can represent quite a couple of programs on a linux system. What you want behind it is either sendmail or postfix. I recommend the latter.
You can install it via your favorite package manager. Then you have to configure it, and once you have done that, you can send email like this:
echo "My message" | mail -s subject [email protected]
See the manual for more information.
As far as configuring postfix goes, there's plenty of articles on the internet on how to do it. Unless you're on a public server with a registered domain, you generally want to forward the email to a SMTP server that you can send email from.
For gmail, for example, follow http://rtcamp.com/tutorials/linux/ubuntu-postfix-gmail-smtp/ or any other similar tutorial.
Suppose you want to insert a particular line of text (not an empty line):

<%origfile% (FOR /L %%i IN (1,1,%totallines%) DO (
SETLOCAL EnableDelayedExpansion
SET /p L=
IF %%i==%insertat% ECHO(!TL!
ECHO(!L!
ENDLOCAL
)
) >%tempfile%
COPY /Y %tempfile% %origfile% >NUL

You can do :

except ValueError :
print("This string doesn't contain an integer")
First, factor consists of indices and levels. This fact is very very important when you are struggling with factor.
For example,
> z <- factor(letters[c(3, 2, 3, 4)])
# human-friendly display, but internal structure is invisible
> z
[1] c b c d
Levels: b c d
# internal structure of factor
> unclass(z)
[1] 2 1 2 3
attr(,"levels")
[1] "b" "c" "d"
here, z
has 4 elements.
The index is 2, 1, 2, 3
in that order.
The level is associated with each index: 1 -> b, 2 -> c, 3 -> d.
Then, as.numeric
converts simply the index part of factor into numeric.
as.character
handles the index and levels, and generates character vector expressed by its level.
?as.numeric
says that Factors are handled by the default method.
Mark, if you check the nerddinner MVC example the logic is pretty much the same.
You only need to retrieve the cookie and set it in the current session.
Global.asax.cs
public override void Init()
{
this.AuthenticateRequest += new EventHandler(WebApiApplication_AuthenticateRequest);
base.Init();
}
void WebApiApplication_AuthenticateRequest(object sender, EventArgs e)
{
HttpCookie cookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName];
FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(cookie.Value);
SampleIdentity id = new SampleIdentity(ticket);
GenericPrincipal prin = new GenericPrincipal(id, null);
HttpContext.Current.User = prin;
}
enter code here
You'll have to define your "SampleIdentity" class, which you can borrow from the nerddinner project.
A DataTable or DataSet object will have a Select Method that will return a DataRow array of results based on the query passed in as it's parameter.
Looking at your requirement your filterexpression will have to be somewhat general to make this work.
myDataTable.Select("columnName1 like '%" + value + "%'");
Another library to consider is MySqlConnector, https://mysqlconnector.net/. Mysql.Data is under a GPL license, whereas MySqlConnector is MIT.
When including files in PHP, it acts like the code exists within the file they are being included from. Imagine copy and pasting the code from within each of your included files directly into your index.php
. That is how PHP works with includes.
So, in your example, since you've set a variable called $name
in your front.inc
file, and then included both front.inc
and end.inc
in your index.php
, you will be able to echo
the variable $name
anywhere after the include
of front.inc
within your index.php
. Again, PHP processes your index.php
as if the code from the two files you are including are part of the file.
When you place an echo
within an included file, to a variable that is not defined within itself, you're not going to get a result because it is treated separately then any other included file.
In other words, to do the behavior you're expecting, you will need to define it as a global.
I understand your frustration the " Graphics view widget" is not the best way to do this, yes it can be done, but it's almost exactly the same as using a label ( for what you want any way) now all the ways listed do work but...

For those who need to convert multiple csv's in a folder, just modify the directory. Outputfilenames will be identical to input, just with another extension.
Take care of the cleanup in the end, if you like to keep the original csv's you might not want to remove these.
Can be easily modifed to save the xlsx in another directory.
$workingdir = "C:\data\*.csv"
$csv = dir -path $workingdir
foreach($inputCSV in $csv){
$outputXLSX = $inputCSV.DirectoryName + "\" + $inputCSV.Basename + ".xlsx"
### Create a new Excel Workbook with one empty sheet
$excel = New-Object -ComObject excel.application
$excel.DisplayAlerts = $False
$workbook = $excel.Workbooks.Add(1)
$worksheet = $workbook.worksheets.Item(1)
### Build the QueryTables.Add command
### QueryTables does the same as when clicking "Data » From Text" in Excel
$TxtConnector = ("TEXT;" + $inputCSV)
$Connector = $worksheet.QueryTables.add($TxtConnector,$worksheet.Range("A1"))
$query = $worksheet.QueryTables.item($Connector.name)
### Set the delimiter (, or ;) according to your regional settings
### $Excel.Application.International(3) = ,
### $Excel.Application.International(5) = ;
$query.TextFileOtherDelimiter = $Excel.Application.International(5)
### Set the format to delimited and text for every column
### A trick to create an array of 2s is used with the preceding comma
$query.TextFileParseType = 1
$query.TextFileColumnDataTypes = ,2 * $worksheet.Cells.Columns.Count
$query.AdjustColumnWidth = 1
### Execute & delete the import query
$query.Refresh()
$query.Delete()
### Save & close the Workbook as XLSX. Change the output extension for Excel 2003
$Workbook.SaveAs($outputXLSX,51)
$excel.Quit()
}
## To exclude an item, use the '-exclude' parameter (wildcards if needed)
remove-item -path $workingdir -exclude *Crab4dq.csv
My problem was that I needed to Reset Window Layout.
There is a way to catch the error directly in the except clause with ConnectionResetError, better to isolate the right error. This example also catches the timeout.
from urllib.request import urlopen
from socket import timeout

except ConnectionResetError:
print("==> ConnectionResetError")
pass
except timeout:
print("==> Timeout")
pass

{
DoSomething();
}
...
}
else { }
As scoota269 says, you should use onSubmit
instead, cause pressing enter on a textbox will most likey trigger a form submit (if inside a form)
<form action="#" onsubmit="handle">
<input type="text" name="txt" />
</form>
<script>
function handle(e){
e.preventDefault(); // Otherwise the form will be submitted
alert("FORM WAS SUBMITTED");
}
</script>
If you want to have an event on the input-field then you need to make sure your handle()
will return false, otherwise the form will get submitted.
<form action="#">
<input type="text" name="txt" onkeypress="handle(event)" />
</form>
<script>
function handle(e){
if(e.keyCode === 13){
e.preventDefault(); // Ensure it is only this code that runs
alert("Enter was pressed was presses");
}
}
</script>
As of iOS 12, NWPathMonitor replaced Reachability. Use this:
import Network
struct Internet {
private static let monitor = NWPathMonitor()
static var active = false
static var expensive = false
/// Monitors internet connectivity changes. Updates with every change in connectivity.
/// Updates variables for availability and if it's expensive (cellular).
static func start() {
guard monitor.pathUpdateHandler == nil else { return }
monitor.pathUpdateHandler = { update in
Internet.active = update.status == .satisfied ? true : false
Internet.expensive = update.isExpensive ? true : false
}
monitor.start(queue: DispatchQueue(label: "InternetMonitor"))
}
}
In use:
Internet.start()
if Internet.active {
// do something
}
if Internet.expensive {
// device is using Cellular data or WiFi hotspot
}
For Bootstrap 4 I find the following very handy because:
It is the combination of col and col-auto which does the magic. So you don't have to define a col width (like col-2,...)
<div class="row">
<div class="col">Left</div>
<div class="col-auto">Right</div>
</div>
Ideal for aligning words, icons, buttons,... to the right.
An example to have this responsive on small devices:
<div class="row">
<div class="col">Left</div>
<div class="col-12 col-sm-auto">Right (Left on small)</div>
</div>

You can use the datedif function to find out difference in days.
=DATEDIF(A1,TODAY(),"d")
Quote from excel.datedif.com
The mysterious datedif function in Microsoft Excel
The Datedif function is used to calculate interval between two dates in days, months or years.
This function is available in all versions of Excel but is not documented. It is not even listed in the "Insert Function" dialog box. Hence it must be typed manually in the formula box. Syntax
DATEDIF( start_date, end_date, interval_unit )
start_date from date end_date to date (must be after start_date) interval_unit Unit to be used for output interval Values for interval_unit
interval_unit Description
D Number of days
M Number of complete months
Y Number of complete years
YD Number of days excluding years
MD Number of days excluding months and years
YM Number of months excluding years
Error Description
#NUM! The end_date is later than (greater than) the start_date or interval_unit has an invalid value. #VALUE! end_date or start_date is invalid.
The genaral form to declare a new array in java is as follows:
type arrayName[] = new type[numberOfElements];
Where type is a primitive type or Object. numberOfElements
is the number of elements you will store into the array and this value can’t change because Java does not support dynamic arrays (if you need a flexible and dynamic structure for holding objects you may want to use some of the Java collections).
Lets initialize an array to store the salaries of all employees in a small company of 5 people:
int salaries[] = new int[5];
The type of the array (in this case int
) applies to all values in the array. You can not mix types in one array.
Now that we have our salaries array initialized we want to put some values into it. We can do this either during the initialization like this:
int salaries[] = {50000, 75340, 110500, 98270, 39400};
Or to do it at a later point like this:
salaries[0] = 50000;
salaries[1] = 75340;
salaries[2] = 110500;
salaries[3] = 98270;
salaries[4] = 39400;
More visual example of array creation:
To learn more about Arrays, check out the guide.
I just want to bring up a valid point to anyone searching for this. If you are going to work with .NET versions before 4.0 (VS2010), please be advised that you have to create constructor chains as shown above.
However, if you're staying in 4.0, I have good news. You can now have a single constructor with optional arguments! I'll simplify the Foo class example:
class Foo {
private int id;
private string name;
public Foo(int id = 0, string name = "") {
this.id = id;
this.name = name;
}
}
class Main() {
// Foo Int:
Foo myFooOne = new Foo(12);
// Foo String:
Foo myFooTwo = new Foo(name:"Timothy");
// Foo Both:
Foo myFooThree = new Foo(13, name:"Monkey");
}
When you implement the constructor, you can use the optional arguments since defaults have been set.
I hope you enjoyed this lesson! I just can't believe that developers have been complaining about construct chaining and not being able to use default optional arguments since 2004/2005! Now it has taken SO long in the development world, that developers are afraid of using it because it won't be backwards compatible.
For the first question I think answer would be:
<your DataFrame>.rename(columns={'count':'Total_Numbers'})
or
<your DataFrame>.columns = ['ID', 'Region', 'Total_Numbers']
As for second one I'd say the answer would be no. It's possible to use it like 'df.ID' because of python datamodel:
Attribute references are translated to lookups in this dictionary, e.g., m.x is equivalent to m.dict["x"]
The lock
statement is translated to calls to the Enter
and Exit
methods of Monitor
.
The lock
statement will wait indefinitely for the locking object to be released.
Easy solution without need for pathes:
open -b com.jetbrains.pycharm
You can set it as alias for every-day easier usage (put to your .bash_rc
etc.):
alias pycharm='open -b com.jetbrains.pycharm'
Usage:
pycharm .
pycharm file.py
I would put the super.super method body in another method, if possible
class SuperSuperClass {
public String toString() {
return DescribeMe();
}
protected String DescribeMe() {
return "I am super super";
}
}
class SuperClass extends SuperSuperClass {
public String toString() {
return "I am super";
}
}
class ChildClass extends SuperClass {
public String toString() {
return DescribeMe();
}
}
Or if you cannot change the super-super class, you can try this:
class SuperSuperClass {
public String toString() {
return "I am super super";
}
}
class SuperClass extends SuperSuperClass {
public String toString() {
return DescribeMe(super.toString());
}
protected String DescribeMe(string fromSuper) {
return "I am super";
}
}
class ChildClass extends SuperClass {
protected String DescribeMe(string fromSuper) {
return fromSuper;
}
}
In both cases, the
new ChildClass().toString();
results to "I am super super"
I guess this is what you need. Try this .
<form action="" method="get">
<input name="search" type="text">
<input type="button" value="Search" onclick="return updateTable();">
</form>
and your javascript code is the same
function updateTable()
{
var photoViewer = document.getElementById('photoViewer');
var photo = document.getElementById('photo1').href;
var numOfPics = 5;
var columns = 3;
var rows = Math.ceil(numOfPics/columns);
var content="";
var count=0;
content = "<table class='photoViewer' id='photoViewer'>";
for (r = 0; r < rows; r++) {
content +="<tr>";
for (c = 0; c < columns; c++) {
count++;
if(count == numOfPics)break; // here is check if number of cells equal Number of Pictures to stop
content +="<td><a href='"+photo+"' id='photo1'><img class='photo' src='"+photo+"' alt='Photo'></a><p>City View</p></td>";
}
content +="</tr>";
}
content += "</table>";
photoViewer.innerHTML = content;
}
ORDER BY article_rating, article_time DESC
will sort by article_time only if there are two articles with the same rating. From all I can see in your example, this is exactly what happens.

An alternative to hard-coding ServicePointManager.SecurityProtocol
or the explicit SchUseStrongCrypto key as mentioned above:
You can tell .NET to use the default SCHANNEL settings with the SystemDefaultTlsVersions key,
e.g.:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319] "SystemDefaultTlsVersions"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319] "SystemDefaultTlsVersions"=dword:00000001
If, for whatever reason (e.g. Space Engineers API), System.array has no definition for Max nor do you have access to Enumerable, a solution for Max of n values is:
public int Max(int[] values) {
if(values.Length < 1) {
return 0;
}
if(values.Length < 2) {
return values[0];
}
if(values.Length < 3) {
return Math.Max(values[0], values[1]);
}
int runningMax = values[0];
for(int i=1; i<values.Length - 1; i++) {
runningMax = Math.Max(runningMax, values[i]);
}
return runningMax;
}
You can use a basic prepend operation on each line:
ls -1 | while read line ; do echo $line ; done
Or you can pipe the output to sed for more complex operations:
ls -1 | sed 's/^\(.*\)$/echo \1/'
public string CreateFile(string id, string name, string description, SupportedPermissions supportedPermissions)
{
file = new File
{
Name = name,
Id = id,
Description = description,
SupportedPermissions = supportedPermissions
};
return file.Id;
}
Combination of Mritunjay and Bartu's answers are full answer to this question. I copying the full example.
<input class="form-control" type="email" required="" placeholder="username"
oninvalid="this.setCustomValidity('Please Enter valid email')"
oninput="setCustomValidity('')"></input>
Here,
this.setCustomValidity('Please Enter valid email')" - Display the custom message on invalidated of the field
oninput="setCustomValidity('')" - Remove the invalidate message on validated filed.
Something like this might help (taken from a working app).
#include <memory>
#include <boost/asio.hpp>
#include <boost/thread.hpp>
struct thread_pool {
typedef std::unique_ptr<boost::asio::io_service::work> asio_worker;
thread_pool(int threads) :service(), service_worker(new asio_worker::element_type(service)) {
for (int i = 0; i < threads; ++i) {
auto worker = [this] { return service.run(); };
grp.add_thread(new boost::thread(worker));
}
}
template<class F>
void enqueue(F f) {
service.post(f);
}
~thread_pool() {
service_worker.reset();
grp.join_all();
service.stop();
}
private:
boost::asio::io_service service;
asio_worker service_worker;
boost::thread_group grp;
};
You can use it like this:
thread_pool pool(2);
pool.enqueue([] {
std::cout << "Hello from Task 1\n";
});
pool.enqueue([] {
std::cout << "Hello from Task 2\n";
});
Keep in mind that reinventing an efficient asynchronous queuing mechanism is not trivial.
Boost::asio::io_service is a very efficient implementation, or actually is a collection of platform-specific wrappers (e.g. it wraps I/O completion ports on Windows).
I got this error when I dynamically read data from a WebRequest

Simple, easy and also disposes/cleans up the object once you are done with it.
In Kotlin language you can do it in this way:
val values = arrayOf(
"cat",
"dog",
"chicken"
)
ArrayAdapter(
this,
android.R.layout.simple_spinner_item,
values
).also {
it.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item)
spinner.adapter = it
}
No, image/jpg
is not the same as image/jpeg
.
You should use image/jpeg
. Only image/jpeg
is recognised as the actual mime type for JPEG files.
See https://tools.ietf.org/html/rfc3745, https://www.w3.org/Graphics/JPEG/ .
Serving the incorrect Content-Type of image/jpg
to IE can cause issues, see http://www.bennadel.com/blog/2609-internet-explorer-aborts-images-with-the-wrong-mime-type.htm.
If you are generating a heap of commands to be run, then call that script from a terminal, you can try the following.
sftp login@host < /path/to/command/list
You will then be asked to enter your password (as per normal) however all the commands in the script run after that.
This is clearly not a completely automated option that can be used in a cron
job, but it can be used from a terminal.
We are looking at building a few helpers, still deciding on APIs and if this goes in core or not. See: https://code.google.com/archive/p/dapper-dot-net/issues/6 for progress.
In the mean time you can do the following
val = "my value";
cnn.Execute("insert into Table(val) values (@val)", new {val});
cnn.Execute("update Table set val = @val where Id = @id", new {val, id = 1});
etcetera
See also my blog post: That annoying INSERT problem
Update
As pointed out in the comments, there are now several extensions available in the Dapper.Contrib project in the form of these IDbConnection
extension methods:
T Get<T>(id);
IEnumerable<T> GetAll<T>();
int Insert<T>(T obj);
int Insert<T>(Enumerable<T> list);
bool Update<T>(T obj);
bool Update<T>(Enumerable<T> list);
bool Delete<T>(T obj);
bool Delete<T>(Enumerable<T> list);
bool DeleteAll<T>();
To add per-class metadata, maybe an annotation might be the correct way to go.
However, you can't enforce the presence of an annotation in the interface, just as you can't enforce static members or the existence of a specific constructor.
Actually, you just have to add the shell=True
argument:
subprocess.call("sleep.sh", shell=True)
But beware -
Warning Invoking the system shell with shell=True can be a security hazard if combined with untrusted input. See the warning under Frequently Used Arguments for details.
you need to call $.uniform.update()
if you update element using javascript as mentioned in the documentation.
No, I don't know of a way to 'screenshot' an element, but what you could do, is draw the quiz results into a canvas element, then use the HTMLCanvasElement
object's toDataURL
function to get a data:
URI with the image's contents.
When the quiz is finished, do this:
var c = document.getElementById('the_canvas_element_id');
var t = c.getContext('2d');
/* then use the canvas 2D drawing functions to add text, etc. for the result */
When the user clicks "Capture", do this:
window.open('', document.getElementById('the_canvas_element_id').toDataURL());
This will open a new tab or window with the 'screenshot', allowing the user to save it. There is no way to invoke a 'save as' dialog of sorts, so this is the best you can do in my opinion.
Ctrl-Alt-X is the keyboard shortcut I use, although that may because I have Resharper
installed - otherwise Ctrl W, X.
From the menu: View -> Toolbox.
You can easily view/change key bindings using Tools -> Options Environment->Keyboard. It has a convenient UI where you can enter a word, and it shows you what key bindings include that word, including View.Toolbox
.
You might want to browse through the online MSDN documentation on getting started with Visual Studio.

FOLDERS
-titled Side Bar to navigate to the first file you want to compare.Diff Files...
There should be a new Tab now showing the comparison.
Original short answer:
Note that:
The "Diff files" only appears with the "folders" sidebar (to open a folder: File->Open Folder) , not with "open files" sidebar.
Almost 9 years late to this but didn't see this variation mentioned accomplishing the same thing (it's kind of a combination of a few of these, similar to to top answer (https://stackoverflow.com/a/1459264/4642530).
Search all detached heads on branch
git reflog show origin/BRANCH_NAME --date=relative
Then find the SHA1 hash
Reset to old SHA1
git reset --hard SHA1
Then push it back up.
git push origin BRANCH_NAME
Done.
This will revert you back to the old commit entirely.
(Including the date of the prior overwritten detached commit head)
This one is for using HTTPClient class
request.headers.add("body", json.encode(map));
I attached the encoded json body data to the header and added to it. It works for me.
The ^M is typically caused by the Windows operator newlines, and translated onto Unix looks like a ^M. The command dos2unix should remove them nicely

I think using multiple Jframe
s is not a good idea.
Instead we can use JPanel
s more than one or more JPanel
in the same JFrame
.
Also we can switch between this JPanel
s. So it gives us freedom to display more than on thing in the JFrame
.
For each JPanel
we can design different things and all this JPanel
can be displayed on the single JFrame
one at a time.
To switch between this JPanel
s use JMenuBar
with JMenuItems
for each JPanel
or 'JButtonfor each
JPanel`.
More than one JFrame
is not a good practice, but there is nothing wrong if we want more than one JFrame
.
But its better to change one JFrame
for our different needs rather than having multiple JFrame
s.
DO it like
$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$yourPHPVAR%'");
Do not forget the %
at the end
Use the range's NumberFormat
property to force the format of the range like this:
Sheet1.Range("A2", "A50000").NumberFormat = "yyyy-mm-dd"
You want the NPGSQL library. Your only other alternative is ODBC.
Beware of the use of push method, if you don't use indexes, it won't work!
var main2dArray: Things[][] = []
main2dArray.push(someTmp1dArray)
main2dArray.push(someOtherTmp1dArray)
gives only a 1 line array!
use
main2dArray[0] = someTmp1dArray
main2dArray[1] = someOtherTmp1dArray
to get your 2d array working!!!
Other beware! foreach doesn't seem to work with 2d arrays!
You can see e.gs. in the documentation demonstrating joris answer. Also from the documentation, you could also set subplots=True
and layout=(,)
within the pandas plot
function:
df.plot(subplots=True, layout=(1,2))
You could also use fig.add_subplot()
which takes subplot grid parameters such as 221, 222, 223, 224, etc. as described in the post here. Nice examples of plot on pandas data frame, including subplots, can be seen in this ipython notebook.
find . | grep KeywordToSearch
Here . means current directory which is value for path parameter for find command. It is piped to grep to search keyword which should return all matching result.
Note: This is case sensitive. So for example fileName
and FileName
are not same.
You can just pass it
def my_function(my_data):
my_data["schoolname"] = "something"
print my_data
or if you really want to
def my_function(**kwargs):
kwargs["schoolname"] = "something"
print kwargs
In an ideal world you'd achieve this simply using the following css
<style type="text/css">
span {
display: inline-block;
width: 50px;
}
</style>
This works on all browsers apart from FF2 and below.
Firefox 2 and lower don't support this value. You can use -moz-inline-box, but be aware that it's not the same as inline-block, and it may not work as you expect in some situations.
Quote taken from quirksmode
You have an error in your syntax here:
this._possessions = new Thing[100]();
This doesn't create an "array of things". To create an array of things, you can simply use the array literal expression:
this._possessions = [];
Of the array constructor if you want to set the length:
this._possessions = new Array(100);
I have created a brief working example you can try in the playground.
module Entities {
class Thing {
}
export class Person {
private _name: string;
private _possessions: Thing[];
private _mostPrecious: Thing;
constructor (name: string) {
this._name = name;
this._possessions = [];
this._possessions.push(new Thing())
this._possessions[100] = new Thing();
}
}
}

If you wanted to do more complicated things like merging events or retry you can use the Observable pattern and a mature library that implements that. https://github.com/ReactiveX/RxPY . Observables are very common in Javascript and Java and very convenient to use for some async tasks.
from rx import Observable, Observer
def push_five_strings(observer):
observer.on_next("Alpha")
observer.on_next("Beta")
observer.on_next("Gamma")
observer.on_next("Delta")
observer.on_next("Epsilon")
observer.on_completed()
class PrintObserver(Observer):
def on_next(self, value):
print("Received {0}".format(value))
def on_completed(self):
print("Done!")
def on_error(self, error):
print("Error Occurred: {0}".format(error))
source = Observable.create(push_five_strings)
source.subscribe(PrintObserver())
OUTPUT:
Received Alpha
Received Beta
Received Gamma
Received Delta
Received Epsilon
Done!
getActiveNetworkInfo
is deprecated from in API 29. So we can use it in bellow 29.
New code in Kotlin for All the API
fun isNetworkAvailable(context: Context): Boolean {
val connectivityManager = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
// For 29 api or above
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
val capabilities = connectivityManager.getNetworkCapabilities(connectivityManager.activeNetwork) ?: return false
return when {
capabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) -> true
capabilities.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET) -> true
capabilities.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) -> true
else -> false
}
}
// For below 29 api
else {
if (connectivityManager.activeNetworkInfo != null && connectivityManager.activeNetworkInfo!!.isConnectedOrConnecting) {
return true
}
}
return false
}
For people running Android Studio
and Eclipse
:
I know that answers are already saturated, but I'll just add that it appears that this error surfaces after installing Android Studio and returning to Eclipse to build and run your project.
Make sure you close all other instances of ADB that may be running (including Android Studio). Once you've done this if you are still having troubles try killing all ADB server processes and restarting. If you haven't setup a global variable, open terminal and navigate to the platform-tools folder of the Android SDK Eclipse is referencing, then run:
./adb kill-server
./adb start-server
From the shell command line:
python file.py
From the Python command line
import file
or
from file import *
You have install nodeJs on your system in order to execute npm
commands. Once npm
is properly working you can visit bower.io
. There you will find complete documentation on this topic. You will find a command $ npm install bower
. this will install bower on your machine. After installing bower you can install Bootstrap easily.
The maximum value of an integer (which is signed) is 2147483647
. If that value overflows, an exception is thrown to prevent unexpected behavior of your program.
If that exception wouldn't be thrown, you'd have a value of -2145629296
for your Volume
, which is most probably not wanted.
Solution: Use an Int64
for your volume. With a max value of 9223372036854775807
, you're probably more on the safe side.
I know the OP specifically mentioned jQuery but I wanted to put an answer here to introduce people to the helpful Underscore library if they are not aware of it already.
By leveraging the keys
method in the Underscore library, you can simply do the following:
_.keys(foo) #=> ["alfa", "beta"]
Plus, there's a plethora of other useful functions that are worth perusing.
Did you download the script from internet?
Then remove NTFS stream from the file using sysinternal's streams.exe on command line.
cmd> streams.exe .\my.ps1
Now try to run the script again.
Here is a simple example.
this method will return a 2 dimensional tType
array
public tType[][] allocate(Class<tType> c,int row,int column){
tType [][] matrix = (tType[][]) Array.newInstance(c,row);
for (int i = 0; i < column; i++) {
matrix[i] = (tType[]) Array.newInstance(c,column);
}
return matrix;
}
say you want a 2 dimensional String array, then call this function as
String [][] stringArray = allocate(String.class,3,3);
This will give you a two dimensional String array with 3 rows and 3 columns;
Note that in Class<tType> c
-> c
cannot be primitive type like say, int
or char
or double
. It must be non-primitive like, String
or Double
or Integer
and so on.
SELECT * FROM INFORMATION_SCHEMA.COLUMNS
The approach you're looking for is FillDown
. Another way so you don't have to kick your head off every time is to store formulas in an array of strings. Combining them gives you a powerful method of inputting formulas by the multitude. Code follows:
Sub FillDown()
Dim strFormulas(1 To 3) As Variant
With ThisWorkbook.Sheets("Sheet1")
strFormulas(1) = "=SUM(A2:B2)"
strFormulas(2) = "=PRODUCT(A2:B2)"
strFormulas(3) = "=A2/B2"
.Range("C2:E2").Formula = strFormulas
.Range("C2:E11").FillDown
End With
End Sub
Screenshots:
Result as of line: .Range("C2:E2").Formula = strFormulas
:
Result as of line: .Range("C2:E11").FillDown
:
Of course, you can make it dynamic by storing the last row into a variable and turning it to something like .Range("C2:E" & LRow).FillDown
, much like what you did.
Hope this helps!
patterns[1]="1\.2\.3\.4.*Has exploded"

Update: for connecting to another sql server and executing sql statements, you have to use sqlcmd Utility. This is typically done in a batch file. You can combine this with xmp_cmdshell if you want to execute it within management studio.

If you're using SSMS (or old school Enterprise Manager) to edit the table directly, press CTRL+0 to add a null.
System.Threading.Thread.Sleep(
(int)System.TimeSpan.FromSeconds(3).TotalMilliseconds);
Or with using
statements:
Thread.Sleep((int)TimeSpan.FromSeconds(2).TotalMilliseconds);
I prefer this to 1000 * numSeconds
(or simply 3000
) because it makes it more obvious what is going on to someone who hasn't used Thread.Sleep
before. It better documents your intent.
I don't think you can use fractional seconds with to_date or the DATE type in Oracle. I think you need to_timestamp which returns a TIMESTAMP type.
C++17 has <experimental\filesystem>
which is based on the boost version.
Use std::experimental::filesystem::remove_all to remove recursively.
If you need more control, try std::experimental::filesystem::recursive_directory_iterator.
You can also write your own recursion with the non-resursive version of the iterator.
namespace fs = std::experimental::filesystem;
void IterateRecursively(fs::path path)
{
if (fs::is_directory(path))
{
for (auto & child : fs::directory_iterator(path))
IterateRecursively(child.path());
}
std::cout << path << std::endl;
}
Can also use:
find . -mindepth 1 -mtime +3 -delete
To not delete target directory
After downloading the two zip files related to Oracle 11G R2. Create a folder in some directory (For say "Oracle_11G_R2"). Extract both zip files into the same folder "Oracle_11G_R2". And run setup.exe file present inside /database/setup.exe. It should run correctly now.
Yes you can do it yourself. It is just a matter of grabbing the sources of the page and parsing them the way you want.
There are various possibilities. A good combo is using python-requests (built on top of urllib2, it is urllib.request
in Python3) and BeautifulSoup4, which has its methods to select elements and also permits CSS selectors:
import requests
from BeautifulSoup4 import BeautifulSoup as bs
request = requests.get("http://foo.bar")
soup = bs(request.text)
some_elements = soup.find_all("div", class_="myCssClass")
Some will prefer xpath parsing or jquery-like pyquery, lxml or something else.
When the data you want is produced by some JavaScript, the above won't work. You either need python-ghost or Selenium. I prefer the latter combined with PhantomJS, much lighter and simpler to install, and easy to use:
from selenium import webdriver
client = webdriver.PhantomJS()

I would advice to start your own solution. You'll understand Scrapy's benefits doing so.
ps: take a look at scrapely: https://github.com/scrapy/scrapely
pps: take a look at Portia, to start extracting information visually, without programming knowledge: https://github.com/scrapinghub/portia
You don't create subfolders of the drawable folder but rather 'sibling' folders next to it under the /res
folder for the different screen densities or screen sizes.
The /drawable
folder (without any dimension) is mostly used for drawables that don't relate to any screen sizes like selector
s.
See this screenshot (use the name drawable-hdpi
instead of mipmap-hdpi
):
Use EntityScanner if you can bear external dependency.It will inject your all entity classes seamlessly even from multiple packages. Just add following line after configuration setup.
Configuration configuration = new Configuration().configure();
EntityScanner.scanPackages("com.fz.epms.db.model.entity").addTo(configuration);
// And following depencency if you are using Maven
<dependency>
<groupId>com.github.v-ladynev</groupId>
<artifactId>fluent-hibernate-core</artifactId>
<version>0.3.1</version>
</dependency>
This way you don't need to declare all entities in hibernate mapping file.
The operating system is also a program, so we can also create our own program by creating from scratch or changing (limiting or adding) features of one of the small operating systems, and then run it during the boot process (using an ISO image).
For example, this page can be used as a starting point:
How to write a simple operating system
Here, the entire Operating System fit entirely in a 512-byte boot sector (MBR)!
Such or similar simple OS can be used to create a simple framework that will allow us:
make the bootloader load subsequent sectors on the disk into RAM, and jump to that point to continue execution. Or you could read up on FAT12, the filesystem used on floppy drives, and implement that.
There are many possibilities, however. For for example to see a bigger x86 assembly language OS we can explore the MykeOS, x86 operating system which is a learning tool to show the simple 16-bit, real-mode OSes work, with well-commented code and extensive documentation.
Other common type of programs that run without the operating system are also Boot Loaders. We can create a program inspired by such a concept for example using this site:
How to develop your own Boot Loader
The above article presents also the basic architecture of such a programs:
- Correct loading to the memory by 0000:7C00 address.
- Calling the BootMain function that is developed in the high-level language.
- Show “”Hello, world…”, from low-level” message on the display.
As we can see, this architecture is very flexible and allows us to implement any program, not necessarily a boot loader.
In particular, it shows how to use the "mixed code" technique thanks to which it is possible to combine high-level constructions (from C or C++) with low-level commands (from Assembler). This is a very useful method, but we have to remember that:
to build the program and obtain executable file you will need the compiler and linker of Assembler for 16-bit mode. For C/C++ you will need only the compiler that can create object files for 16-bit mode.
The article shows also how to see the created program in action and how to perform its testing and debug.
The above examples used the fact of loading the sector MBR on the data medium. However, we can go deeper into the depths by plaing for example with the UEFI applications:
Beyond loading an OS, UEFI can run UEFI applications, which reside as files on the EFI System Partition. They can be executed from the UEFI command shell, by the firmware's boot manager, or by other UEFI applications. UEFI applications can be developed and installed independently of the system manufacturer.
A type of UEFI application is an OS loader such as GRUB, rEFInd, Gummiboot, and Windows Boot Manager; which loads an OS file into memory and executes it. Also, an OS loader can provide a user interface to allow the selection of another UEFI application to run. Utilities like the UEFI shell are also UEFI applications.
If we would like to start creating such programs, we can, for example, start with these websites:
Programming for EFI: Creating a "Hello, World" Program / UEFI Programming - First Steps
It is well known that there is a whole group of malicious software (which are programs) that are running before the operating system starts.
A huge group of them operate on the MBR sector or UEFI applications, just like the all above solutions, but there are also those that use another entry point such as the Volume Boot Record (VBR) or the BIOS:
There are at least four known BIOS attack viruses, two of which were for demonstration purposes.
or perhaps another one too.
Bootkits have evolved from Proof-of-Concept development to mass distribution and have now effectively become open-source software.
I also think that in this context it is also worth mentioning that there are various forms of booting the operating system (or the executable program intended for this). There are many, but I would like to pay attention to loading the code from the network using Network Boot option (PXE), which allows us to run the program on the computer regardless of its operating system and even regardless of any storage medium that is directly connected to the computer:
this is what it worked for me:
select * from table
where column
BETWEEN STR_TO_DATE('29/01/15', '%d/%m/%Y')
AND STR_TO_DATE('07/10/15', '%d/%m/%Y')
Please, note that I had to change STR_TO_DATE(column, '%d/%m/%Y') from previous solutions, as it was taking ages to load
Not paying enough attention towards managing database connections in your application. Then you find out the application, the computer, the server, and the network is clogged.
I always get merge conflicts when doing just git merge feature-branch
. This seems to work for me:
git checkout -b feature-branch
Do a bunch of code changes...
git merge -s ours master
git checkout master
git merge feature-branch
or
git checkout -b feature-branch
Do a bunch of code changes...
git checkout master
git merge -X theirs feature-branch
Your approach won't deal with lot of names correctly but...
SELECT CASE
WHEN name LIKE '% %' THEN LEFT(name, Charindex(' ', name) - 1)
ELSE name
END,
CASE
WHEN name LIKE '% %' THEN RIGHT(name, Charindex(' ', Reverse(name)) - 1)
END

The specific instructions for what you are looking for are in here: https://support.google.com/docs/answer/3093281
Remember your Google Spreadsheets Formulas might use semicolon (;) instead of comma (,) depending on Regional Settings.
Once made the replacement on some examples would look like this:
=GoogleFinance("CURRENCY:USDEUR")
=INDEX(GoogleFinance("USDEUR","price",today()-30,TODAY()),2,2)
=SPARKLINE(GoogleFinance("USDEUR","price",today()-30,today()))
To find case Insensitive string use this,
var thename = "Andrew";
db.collection.find({"name":/^thename$/i})
This is how you should be using mysql_fetch_assoc():
$result = mysql_query($query);
while ($row = mysql_fetch_assoc($result)) {
// Do stuff with $row
}
$result should be a resource. Even if the query returns no rows, $result is still a resource. The only time $result is a boolean value, is if there was an error when querying the database. In which case, you should find out what that error is by using mysql_error() and ensure that it can't happen. Then you don't have to hide from any errors.
You should always cover the base that errors may happen by doing:
if (!$result) {
die(mysql_error());
}
At least then you'll be more likely to actually fix the error, rather than leave the users with a glaring ugly error in their face.
Try:
![image|<SCALE(64x64)>](IMG_URL)

For me this error occurred because I had 2 web API actions that had the exact same signatures and both had the same verbs, HttpPost
, what I did was change one of the verbs (the one used for updating) to PUT and the error was removed. The following in my catch statement helped in getting to the root of the problem:
catch (WebException webex)
{
WebResponse errResp = webex.Response;
using (Stream respStream = errResp.GetResponseStream())
{
StreamReader reader = new StreamReader(respStream);
string text = reader.ReadToEnd();
}
}
Btw, now ruby already supports just strip without "!".
Compare:
p "abc".strip! == " abc ".strip! # false, because "abc".strip! will return nil
p "abc".strip == " abc ".strip # true
Also it's impossible to strip
without duplicates. See sources in string.c:
static VALUE
rb_str_strip(VALUE str)
{
str = rb_str_dup(str);
rb_str_strip_bang(str);
return str;
}
ruby 1.9.3p0 (2011-10-30) [i386-mingw32]

Update2:

will not create duplicates — both in 1.9.x, 2.x and trunk versions.
In practice, the models are used as follows.
In discriminative models, to predict the label y
from the training example x
, you must evaluate:
which merely chooses what is the most likely class y
considering x
. It's like we were trying to model the decision boundary between the classes. This behavior is very clear in neural networks, where the computed weights can be seen as a complexly shaped curve isolating the elements of a class in the space.
Now, using Bayes' rule, let's replace the in the equation by . Since you are just interested in the arg max, you can wipe out the denominator, that will be the same for every y
. So, you are left with
which is the equation you use in generative models.
While in the first case you had the conditional probability distribution p(y|x)
, which modeled the boundary between classes, in the second you had the joint probability distribution p(x, y)
, since p(x | y) p(y) = p(x, y)
, which explicitly models the actual distribution of each class.
With the joint probability distribution function, given a y
, you can calculate ("generate") its respective x
. For this reason, they are called "generative" models.
The schema definition for an attribute determines whether an attribute must have a value. If the manager
attribute in the example given is the attribute defined in RFC4524 with OID 0.9.2342.19200300.100.1.10
, then that attribute has DN syntax. DN syntax is a sequence of relative distinguished names and must not be empty. The filter given in the example is used to cause the LDAP directory server to return only entries that do not have a manager
attribute to the LDAP client in the search result.
if you have the file object, then
>>> import os
>>> with open('new_file.txt') as my_file:
... my_file.seek(0, os.SEEK_END) # go to end of file
... if my_file.tell(): # if current position is truish (i.e != 0)
... my_file.seek(0) # rewind the file for later use
... else:
... print "file is empty"
...
file is empty
// import
const fs = require('fs') // in javascript
import * as fs from "fs" // in typescript
import fs from "fs" // in typescript
// use
!fs.existsSync(`./assets/`) && fs.mkdirSync(`./assets/`, { recursive: true })
What do you think this is supposed to be: ((t[1])/length) * t[1] += string
Python can't parse this, it's a syntax error.
You can configure it with the "XAMPP Shell" (command prompt). Open the shell and execute this command:
mysqladmin.exe -u root password secret
Just use multiple in-clauses to get around this:
select field1, field2, field3 from table1
where name in ('value1', 'value2', ..., 'value999')
or name in ('value1000', ..., 'value1999')
or ...;
A Drawable
can be drawn onto a Canvas
, and a Canvas
can be backed by a Bitmap
:
(Updated to handle a quick conversion for BitmapDrawable
s and to ensure that the Bitmap
created has a valid size)
public static Bitmap drawableToBitmap (Drawable drawable) {
if (drawable instanceof BitmapDrawable) {
return ((BitmapDrawable)drawable).getBitmap();
}
int width = drawable.getIntrinsicWidth();
width = width > 0 ? width : 1;
int height = drawable.getIntrinsicHeight();
height = height > 0 ? height : 1;
Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
drawable.draw(canvas);
return bitmap;
}
I have come to the same problem and fixed the same way as Alex K.
So if "Send Errors To Browser" is not working set also this:
Error Pages -> 500 -> Edit Feature Settings -> "Detailed Errors"
Also note that if the content of the error page sent back is quite short and you're using IE, IE will happily ignore the useful content sent back by the server and show you its own generic error page instead. You can turn this off in IE's options, or use a different browser.
The output of dpkg -s ...
demonstrates that docker-compose
is not installed from a package. Without more information from you there are at least two possibilities:
docker-compose simply isn't installed at all, and you need to install it.
The solution here is simple: install docker-compose
.
docker-compose is installed in your $HOME
directory (or other location not on root's $PATH
).
There are several solution in this case. The easiest is probably to replace:
sudo docker-compose ...
With:
sudo `which docker-compose` ...
This will call sudo
with the full path to docker-compose
.
You could alternatively install docker-compose
into a system-wide directory, such as /usr/local/bin
.

from the pandas doc http://pandas.pydata.org/pandas-docs/stable/dsintro.html Series is a one-dimensional labeled array capable of holding any data type. To read data in form of panda Series:
import pandas as pd
ds = pd.Series(data, index=index)
DataFrame is a 2-dimensional labeled data structure with columns of potentially different types.
import pandas as pd
df = pd.DataFrame(data, index=index)
In both of the above index is list
for example: I have a csv file with following data:
,country,popuplation,area,capital
BR,Brazil,10210,12015,Brasile
RU,Russia,1025,457,Moscow
IN,India,10458,457787,New Delhi
To read above data as series and data frame:
import pandas as pd
file_data = pd.read_csv("file_path", index_col=0)
d = pd.Series(file_data.country, index=['BR','RU','IN'] or index = file_data.index)
output:
>>> d
BR Brazil
RU Russia
IN India
df = pd.DataFrame(file_data.area, index=['BR','RU','IN'] or index = file_data.index )
output:
>>> df
area
BR 12015
RU 457
IN 457787
LIMIT 1
is what you want. Just keep in mind this returns the first record in the result set regardless of order (unless you specify an order
clause in an outer query).
Another easy way to do this is by using the following syntax to iterate through the object, keeping access to the key and value:
for(var key in object){
console.log(key + ' - ' + object[key])
}
so for yours:
for(var key in obj){
console.log(key + ' - ' + obj[key])
}
There are several ways to do that. Using HTML alone, you can write
<table border=1 frame=void rules=rows>
or, if you want a border above the first row and below the last row too,
<table border=1 frame=hsides rules=rows>
This is rather inflexible, though; you cannot e.g. make the lines dotted this way, or thicker than one pixel. This is why in the past people used special separator rows, consisting of nothing but some content intended to produce a line (it gets somewhat dirty, especially when you need to make rows e.g. just a few pixels high, but it’s possible).
For the most of it, people nowadays use CSS border
properties for the purpose. It’s fairly simple and cross-browser. But note that to make the lines continuous, you need to prevent spacing between cells, using either the cellspacing=0
attribute in the table
tag or the CSS rule table { border-collapse: collapse; }
. Removing such spacing may necessitate adding some padding (with CSS, preferably) inside the cells.
At the simplest, you could use
<style>
table {
border-collapse: collapse;
}
tr {
border: solid;
border-width: 1px 0;
}
</style>
This puts a border above the first row and below the last row too. To prevent that, add e.g. the following into the style sheet:
tr:first-child {
border-top: none;
}
tr:last-child {
border-bottom: none;
}
Like the others said, ISO C++ doesn't support that. But you can workaround it. Just use std::vector instead.
int* a = new int[N];
// fill a
class C {
const std::vector<int> v;
public:
C():v(a, a+N) {}
};
It seems to be a long-running framework process for debugging (to decrease load times?). I discovered that when you start your application twice from the debugger often the same vshost.exe process will be used. It just unloads all user-loaded DLLs first. This does odd things if you are fooling around with API hooks from managed processes.
You can try this as well:
from time import perf_counter
t0 = perf_counter()
...
t1 = perf_counter()
time_taken = t1 - t0

I asked the original question - @Trott's answer is surely the best.
However with JS being a dynamic language and with there being so many JS runtime environments, the instanceof
operator can fail especially in front-end development when crossing boundaries such as iframes. See:
https://github.com/mrdoob/three.js/issues/5886
If you are ok with duck typing, this should be good:
let isError = function(e){
return e && e.stack && e.message;
}
I personally prefer statically typed languages, but if you are using a dynamic language, it's best to embrace a dynamic language for what it is, rather than force it to behave like a statically typed language.
if you wanted to get a little more precise, you could do this:
let isError = function(e){
return e && e.stack && e.message && typeof e.stack === 'string'
&& typeof e.message === 'string';
}
Encapsulation is what it sounds like, a way of putting a box around something to protect its contents. Abstraction is extracting the functional properties of something such that you can perform operations using only what you've extracted without knowledge of the inner workings.
When we say that two substances are liquids we are using "liquid" as an abstraction over the properties of those substances we're choosing to discuss. That abstraction tells us the things we can do with the substances given our previous experience with liquids.
Abstraction also doesn't really have anything to do with heirarchies. You can have another abstraction like "metals" that extracts properties of substances in a different way.
Abstractions forget details, so if you're using a particular abstraction you shouldn't ask about properties of the underlying substance that aren't granted by the abstraction. Like if you take milk and water and mix them together, you have a hard time then asking how much milk you have.
A Functor is an abstraction over something that has some notion of map, that is, you can run a function on its inner contents that transforms the inner bit into anything else. The outer something stays the same kind of thing.
Where this gets useful is that if you have a function that works on Lists and you realise you're only depending on the map interface, you can instead depend on Functor and then your function can work with streams, promises, maybes, tuples, and anything else that shares that abstraction.
Functional languages like Haskell have some really great powers of abstraction that make extreme code reuse practical.

Your question is a little unclear, but if what you're doing is trying to get your friend's latest changes, then typically what your friend needs to do is to push those changes up to a remote repo (like one hosted on GitHub), and then you fetch or pull those changes from the remote:
Your friend pushes his changes to GitHub:
git push origin <branch>
Clone the remote repository if you haven't already:
git clone https://[email protected]/abc/theproject.git
Fetch or pull your friend's changes (unnecessary if you just cloned in step #2 above):
git fetch origin
git merge origin/<branch>
Note that git pull
is the same as doing the two steps above:
git pull origin <branch>

I had a similar issue as I pasted some text from a binary Kafka message, which inserted non-visible character and caused git to think the file is binary.
I found the offending characters by searching the file using regex [^ -~\n\r\t]+
.
[
match characters in this set^
match characters not in this set -~
matches all characters from ' ' (space) to '~'\n
newline\r
carriage return\t
tab]
close set+
match one or more of these charactersSetX is the command that you'll need in most of the cases.Though its possible to use REG or REGEDIT
Using registry editing commands you can avoid some of the restrictions of the SetX command - different data types, variables containing =
in their name and so on.
@echo off
:: requires admin elevated permissions
::setting system variable
REG ADD "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v MyVar /D MyVal
::expandable variable
REG ADD "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /T REG_EXPAND_SZ /v MyVar /D MyVal
:: does not require admin permissions
::setting user variable
REG ADD "HKEY_CURRENT_USER\Environment" /v =C: /D "C:\\test"
REG is the pure registry client but its possible also to import the data with REGEDIT though it allows using only hard coded values (or generation of a temp files). The example here is a hybrid file that contains both batch code and registry data (should be saved as .bat
- mind that in batch ;
are ignored as delimiters while they are used as comments in .reg
files):
REGEDIT4
; @ECHO OFF
; CLS
; REGEDIT.EXE /S "%~f0"
; EXIT
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]
"SystemVariable"="GlobalValue"
[HKEY_CURRENT_USER\Environment]
"UserVariable"="SomeValue"
Very old question, but in case someone else stumbles across it, I would recommend trying:

scrollTop: $j('#main').offset().top
}, 300);

From the link you can do it easily as I added the screenshot of it step by step.
If you have Key-store file then you can do same simply.
Go to Build then click on Generate Signed APK
There is a package called eclipse-cdt
in the Ubuntu 12.10 repositories, this is what you want. If you haven't got g++
already, you need to install that as well, so all you need is:
sudo apt-get install eclipse eclipse-cdt g++
Whether you messed up your system with your previous installation attempts depends heavily on how you did it. If you did it the safe way for trying out new packages not from repositories (i.e., only installed in your home folder, no sudo
s blindly copied from installation manuals...) you're definitely fine. Otherwise, you may well have thousands of stray files all over your file system now. In that case, run all uninstall scripts you can find for the things you installed, then install using apt-get
and hope for the best.
Why don't you use
DbTestDataContext obj = new DbTestDataContext();
var q =from a in obj.GetTable<TableName>() select a;
This is simple.
Use
import Home from './layouts/Home'
rather than
import { Home } from './layouts/Home'
Remove {}
from Home
Launching the AVD Manager from Visual Studio 2015 resolved this issue for me.
I had (a lot of packages) all the required packages installed but hadn't used them for some time & had issues detecting them in the SDK manager. I attempted all the solutions provided above to no avail, including running the AVD after running the monitor.bat file in 'android/sdk/tools'.
I then launched the AVD from VS in 'Tools->Android->Android Emulator Manager' and it detected both 'Google APIs Intel Atom x86' & the ARM EABI v7a system Images right off the bat!
Target is set to API Level 23.

Maybe this one can help:
function focus(el){_x000D_
el.focus();_x000D_
return el==document.activeElement;_x000D_
}
_x000D_
return value: true = success, false = failed
Reff: https://developer.mozilla.org/en-US/docs/Web/API/DocumentOrShadowRoot/activeElement https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/focus
window.location.href
will give you the current url (as shown in the browser address). After parsing it and retrieving the relevant part you would compare it with each link href and assign the active
class to the corresponding link.
If you read the message carefully you will see that you are using the permissions like camera, Microphone, Contacts, Storage and Phone, etc. and you don't supply a privacy policy. you need to supply a privacy policy if you do that. you can find more information about the android privacy policy on google
To Add Privacy Policy In-Play Console,
Find and select All Apps.
Select the application you need to add your Privacy Policy to.
Find the Policy at the end of the page.
Click App content to edit the listing for your app.
Find the field labeled Privacy Policy and place the URL of the page of your Privacy Policy
Click Save and you are good to go.
Note: You need to have a public web page to host your Privacy Policy. Google Play Store won't host the policy for you.
The instance that your base class reference is referring to is not an instance of your child class. There's nothing wrong.
More specifically:
Base derivedInstance = new Derived();
Base baseInstance = new Base();
Derived good = (Derived)derivedInstance; // OK
Derived fail = (Derived)baseInstance; // Throws InvalidCastException
For the cast to be successful, the instance that you're downcasting must be an instance of the class that you're downcasting to (or at least, the class you're downcasting to must be within the instance's class hierarchy), otherwise the cast will fail.
Update August 2016:
Tejas Padliya adds in the comments:
Dark theme works well with Eclipse 4.5 onward with Windows 10.
No more black text on black background
Update June 2014:
As mentioned din "Dark Theme, Top Eclipse Luna Feature #5", Eclipse 4.4 (Luna) has a dark theme included in it (see informatik01's comment):
When Eclipse 3.0 shipped in 2004 it brought a new look to the workbench. Now, 10 years later, an entirely new Dark Theme is launching.
The theme extends to more than just the Widgets. Syntax highlighting has also been improved to take advantage of the new look.
The What's new page mentions:
A new dark window theme has been introduced. This popular community theme demonstrates the power of the underlying Eclipse 4 styling engine.
You can enable it from theGeneral > Appearance
preference page.
Plug-ins can contribute extensions to this theme to style their own specific views and editors to match the window theme.
Update April 2013:
It seems the solution below don't work well with Eclipse Juno 4.2 and Windows 8, according to Lennart in the comments.
One solution which (mostly) work is the Eclipse Chrome Theme (compatible Juno 4.2 and even Kepler 4.3), from the GitHub project eclipse-themes, by Jeeeyul Lee.
This post mentions:
The first is to change the appearance of what is inside the editor windows.
That can be done with the Eclipse Colour Theme plugin (http://eclipsecolorthemes.org/). My favourite editor theme is Vibrant Ink with the Monaco font. They explain how to install their themes very well (http://eclipsecolorthemes.org/?view=how-to-use), although you get a fine set of dark themes with the default plugin install and may not need to come back to their website for any more. Get the plugin here.The second stage is darkening the chrome of the UI, which is all the widgets and menus and everything outside of the child window canvases.
This plugin gives you a GUI editor for the chrome colour scheme: https://github.com/jeeeyul/eclipse-themes/.
If you want a dark one, go ahead and click away until eclipse is dark.Once you are done, some GUI surface area will show through the system theme as mentioned at the top of this post.
Rather than using that editor, you could install the pre-baked Dark Juno theme instead.
The install is manual.
Start by downloading it from here: https://github.com/eclipse-color-theme/eclipse-ui-themes.
It has to be copied into your eclipse dropins folder. This lives next to the eclipse executable, not in your workspace or someplace like that. In my case the command to do the copy was:
cp ./plugins/com.github.eclipsecolortheme.themes_1.0.0.201207121019.jar /usr/lib/eclipse/dropins/
You could be running eclipse from any directory though, so which eclipse will tell you where it should go.
Restart eclipse and you should find a Dark Juno option underPreferences::General::Appearance
. It is a nice neutral grey with some gradients and is a very good option.
~~~~~~~~~~~~~~
Update December 2012 (20 months later):
The blog post "Jin Mingjian: Eclipse Darker Theme" mentions this GitHub repo "eclipse themes - darker":
The big fun is that, the codes are minimized by using Eclipse4 platform technologies like dependency injection.
It proves that again, the concise codes and advanced features could be achieved by contributing or extending with the external form(like library, framework).
New language is not necessary just for this kind of purpose.
Update July 2012 (15 months later):
I have seen one! (Ie, a fully dark theme for Eclipse), as reported by Lars Vogel in "Eclipse 4 is beautiful – Create your own Eclipse 4 theme":
If you want to play with it, you only need to write a plug-in, create a CSS file and use the
org.eclipse.e4.ui.css.swt.theme
extension point to point to your file.
If you export your plug-in, place it in the “dropins” folder of your Eclipse installation and your styling is available.
pixeldude mentions in the comments having publish "Dark Juno" on GitHub!
Komododave mentions that you don't always need a plugin: see "Ubuntu + Eclipse 4.2 - Dark theme - How to darken sidebar backgrounds?" for an example, based on gtkrc resource.
Original answer: March 2011
Note that a full dark theme will be possible with e4.
(see dynamic css with e4 or A week at e4 – Themeing in e4):
In the meantime, only for editors though (which isn't what you want but still merit to be mentioned):
"Fresh up your Eclipse with super-awesome color themes!"

getJSON will evaluate the data to JSON for you, as long as the correct content-type is used. Make sure that the server is returning the data as application/json.
Also make sure the user issuing the query has been granted the necessary permissions.
For queries on tables you need to grant SELECT permission.
For queries on other object types (e.g. stored procedures) you need to grant EXECUTE permission.

I can fix this by adding below code in my JSP file. Now both model and UI values are same.
<div ng-show="false">
{{dt = (dt | date:'dd-MMMM-yyyy') }}
</div>
function GET() {
var data = [];
for(x = 0; x < arguments.length; ++x)
data.push(location.href.match(new RegExp("/\?".concat(arguments[x],"=","([^\n&]*)")))[1])
return data;
}
example:
data = GET("id","name","foo");
query string : ?id=3&name=jet&foo=b
returns:
data[0] // 3
data[1] // jet
data[2] // b
or
alert(GET("id")[0]) // return 3

Use DATESTR
>> datestr(40189)
ans =
12-Jan-0110
Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM
>> datenum(2010,1,11)
ans =
734149
>> datenum(2010,1,11)-40189
ans =
693960
>> datestr(40189+693960)
ans =
11-Jan-2010
In other words, to convert any serial Excel date, call
datestr(excelSerialDate + 693960)
EDIT
To get the date in mm/dd/yyyy format, call datestr
with the specified format
excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010
Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things
excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010
This exception is also thrown when a non-existent property is being updated dynamically, using reflection.
If one is using reflection to dynamically update property values, it's worth checking to make sure the passed PropertyName
is identical to the actual property.
In my case, I was attempting to update Employee.firstName
, but the property was actually Employee.FirstName
.
Worth keeping in mind. :)
Exceptions bubble up the stack. If a caller calls a method that throws a checked exception, like IOException, it must also either catch the exception, or itself throw it.
In the case of the first block:
filecontent()
{
setGUI();
setRegister();
showfile();
setTitle("FileData");
setVisible(true);
setSize(300, 300);
/*
addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent we)
{
System.exit(0);
}
});
*/
}
You would have to include a try catch block:
filecontent()
{
setGUI();
setRegister();
try {
showfile();
}
catch (IOException e) {
// Do something here
}
setTitle("FileData");
setVisible(true);
setSize(300, 300);
/*
addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent we)
{
System.exit(0);
}
});
*/
}
In the case of the second:
public void actionPerformed(ActionEvent ae)
{
if (ae.getSource() == submit)
{
showfile();
}
}
You cannot throw IOException from this method as its signature is determined by the interface, so you must catch the exception within:
public void actionPerformed(ActionEvent ae)
{
if(ae.getSource()==submit)
{
try {
showfile();
}
catch (IOException e) {
// Do something here
}
}
}
Remember, the showFile() method is throwing the exception; that's what the "throws" keyword indicates that the method may throw that exception. If the showFile() method is throwing, then whatever code calls that method must catch, or themselves throw the exception explicitly by including the same throws IOException addition to the method signature, if it's permitted.
If the method is overriding a method signature defined in an interface or superclass that does not also declare that the method may throw that exception, you cannot declare it to throw an exception.
Quick answer
On src, you can always specify files to ignore using "!".
Example (you want to exclude all *.min.js files on your js folder and subfolder:
gulp.src(['js/**/*.js', '!js/**/*.min.js'])
You can do it as well for individual files.
Expanded answer:
Extracted from gulp documentation:
gulp.src(globs[, options])
Emits files matching provided glob or an array of globs. Returns a stream of Vinyl files that can be piped to plugins.
glob refers to node-glob syntax or it can be a direct file path.
So, looking to node-glob documentation we can see that it uses the minimatch library to do its matching.
On minimatch documentation, they point out the following:
if the pattern starts with a ! character, then it is negated.
And that is why using ! symbol will exclude files / directories from a gulp task
I had same issue on windows 8.1
The solution which worked for me is to specify config file path correctly
Going to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > services > MongoDB > imagePath
the value was like the following:
"C:\Program Files\MongoDB 2.6 Standard\bin\mongod.exe" --config mongod.cfg --service
Then just I corrected config file path to match my actual path:
"C:\Program Files\MongoDB 2.6 Standard\bin\mongod.exe" --config "d:\mongodb\mongod.cfg" --service

Also, if you cannot find your eclipse dir. Because, I had such problem on mac we can remember that eclipse is using OSGi, so we can go to Target Platform and disable features/plugins that were described above: org.eclipse.jpt.*
I recently found this library that converts an Excel workbook file into a DataSet: Excel Data Reader
A good example of real time found from here:-
A concrete example of an abstract class would be a class called Animal. You see many animals in real life, but there are only kinds of animals. That is, you never look at something purple and furry and say "that is an animal and there is no more specific way of defining it". Instead, you see a dog or a cat or a pig... all animals. The point is, that you can never see an animal walking around that isn't more specifically something else (duck, pig, etc.). The Animal is the abstract class and Duck/Pig/Cat are all classes that derive from that base class. Animals might provide a function called "Age" that adds 1 year of life to the animals. It might also provide an abstract method called "IsDead" that, when called, will tell you if the animal has died. Since IsDead is abstract, each animal must implement it. So, a Cat might decide it is dead after it reaches 14 years of age, but a Duck might decide it dies after 5 years of age. The abstract class Animal provides the Age function to all classes that derive from it, but each of those classes has to implement IsDead on their own.
A business example:
I have a persistance engine that will work against any data sourcer (XML, ASCII (delimited and fixed-length), various JDBC sources (Oracle, SQL, ODBC, etc.) I created a base, abstract class to provide common functionality in this persistance, but instantiate the appropriate "Port" (subclass) when persisting my objects. (This makes development of new "Ports" much easier, since most of the work is done in the superclasses; especially the various JDBC ones; since I not only do persistance but other things [like table generation], I have to provide the various differences for each database.) The best business examples of Interfaces are the Collections. I can work with a java.util.List without caring how it is implemented; having the List as an abstract class does not make sense because there are fundamental differences in how anArrayList works as opposed to a LinkedList. Likewise, Map and Set. And if I am just working with a group of objects and don't care if it's a List, Map, or Set, I can just use the Collection interface.
I found a solution that is more efficient than currently accepted answer, because current answer forces all list elements to be refreshed. My solution will refresh only one element (that was touched) by calling adapters getView and recycling current view which adds even more efficiency.
mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// Edit object data that is represented in Viewat at list's "position"
view = mAdapter.getView(position, view, parent);
}
});
You can also use Boost.Assignment:
const list<int> primes = list_of(2)(3)(5)(7)(11);
vector<int> v;
v += 1,2,3,4,5,6,7,8,9;
I love this
$data = str_getcsv($CsvString, "\n"); //parse the rows
foreach ($data as &$row) {
$row = str_getcsv($row, "; or , or whatever you want"); //parse the items in rows
$this->debug($row);
}
in my case I am going to get a csv through web services, so in this way I don't need to create the file. But if you need to parser with a file, it's only necessary to pass as string
str.split (" ")
res27: Array[java.lang.String] = Array(a, +, b, -, c, *, d, /, e, <, f, >, g, >=, h, <=, i, ==, j)
{yourImageName.Source = new BitmapImage(new Uri("ms-appx:///Assets/LOGO.png"));}
LOGO refers to your image
Hoping to help anyone. :)
Another approach with lapply and a dplyr statement. We can apply an arbitrary number of whatever summary functions to the same statement:
lapply(c(first, last),
function(x) df %>% group_by(id) %>% summarize_all(funs(x))) %>%
bind_rows()
You could for example be interested in rows with the max stopSequence value as well and do:
lapply(c(first, last, max("stopSequence")),
function(x) df %>% group_by(id) %>% summarize_all(funs(x))) %>%
bind_rows()
In my case only deleting of the local version and re checkout of fresh copy was a solution.

I've run into this with a couple virtual environments.

Worked both times.
If you use ng > 1.2, here is an example of using ng-repeat-start/end
without generating unnecessary tags:
<html>_x000D_
<head>_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
<script>_x000D_
angular.module('mApp', []);_x000D_
</script>_x000D_
</head>_x000D_
<body ng-app="mApp">_x000D_
<table border="1" width="100%">_x000D_
<tr ng-if="0" ng-repeat-start="elem in [{k: 'A', v: ['a1','a2']}, {k: 'B', v: ['b1']}, {k: 'C', v: ['c1','c2','c3']}]"></tr>_x000D_
_x000D_
<tr>_x000D_
<td rowspan="{{elem.v.length}}">{{elem.k}}</td>_x000D_
<td>{{elem.v[0]}}</td>_x000D_
</tr>_x000D_
<tr ng-repeat="v in elem.v" ng-if="!$first">_x000D_
<td>{{v}}</td>_x000D_
</tr>_x000D_
_x000D_
<tr ng-if="0" ng-repeat-end></tr>_x000D_
</table>_x000D_
</body>_x000D_
</html>
_x000D_
The important point: for tags used for ng-repeat-start
and ng-repeat-end
set ng-if="0"
, to let not be inserted in the page. In this way the inner content will be handled exactly as it is in knockoutjs (using commands in <!--...-->
), and there will be no garbage.
While in 2010, java.util.Date
was the class we all used (toghether with DateFormat
and Calendar
), those classes were always poorly designed and are now long outdated. Today one would use java.time, the modern Java date and time API.
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("d-MMM-yyyy,HH:mm:ss");
String dateTimeStringFromSqlite = "29-Apr-2010,13:00:14";
LocalDateTime dateTime = LocalDateTime.parse(dateTimeStringFromSqlite, formatter);
System.out.println("output here: " + dateTime);
Output is:
output here: 2010-04-29T13:00:14
The combination of uppercase HH
and aaa
in your format pattern strings does not make much sense since HH
is for hour of day, rendering the AM/PM marker from aaa
superfluous. It should not do any harm, though, and I have been unable to reproduce the exact results you reported. In any case, your comment is to the point no matter if one uses the old-fashioned SimpleDateFormat
or the modern DateTimeFormatter
:
'aaa' should not be used, if you use 'aaa' then specify 'hh'
Lowercase hh
is for hour within AM or PM, from 01 through 12, so would require an AM/PM marker.
Other tips
2010-04-29T07:30:14Z
(the modern Instant
class parses and formats such strings as its default, that is, without any explicit formatter).GMT+05:30
for time zone. Prefer a real time zone, for example Asia/Colombo, Asia/Kolkata or America/New_York.DateFormat
, its parse
method returns a Date
, so you don’t need the cast in Date lNextDate = (Date)lFormatter.parse(lNextDate);
.Yes, java.time works nicely on older and newer Android devices. It just requires at least Java 6.
org.threeten.bp
with subpackages.java.time
.java.time
was first described.java.time
to Java 6 and 7 (ThreeTen for JSR-310).Another alternative approach is:
How do I create a Java string from the contents of a file?
Other option is to use utilities provided open source libraries
http://commons.apache.org/io/api-1.4/index.html?org/apache/commons/io/IOUtils.html
Why java doesn't provide such a common util API ?
a) to keep the APIs generic so that encoding, buffering etc is handled by the programmer.
b) make programmers do some work and write/share opensource util libraries :D ;-)
String[] split = data.split("\\|",-1);
This is not the actual requirement in all the time. The Drawback of above is show below:
Scenerio 1:
When all data are present:
String data = "5|6|7||8|9|10|";
String[] split = data.split("\\|");
String[] splt = data.split("\\|",-1);
System.out.println(split.length); //output: 7
System.out.println(splt.length); //output: 8
When data is missing:
Scenerio 2: Data Missing
String data = "5|6|7||8|||";
String[] split = data.split("\\|");
String[] splt = data.split("\\|",-1);
System.out.println(split.length); //output: 5
System.out.println(splt.length); //output: 8
Real requirement is length should be 7 although there is data missing. Because there are cases such as when I need to insert in database or something else. We can achieve this by using below approach.
String data = "5|6|7||8|||";
String[] split = data.split("\\|");
String[] splt = data.replaceAll("\\|$","").split("\\|",-1);
System.out.println(split.length); //output: 5
System.out.println(splt.length); //output:7
What I've done here is, I'm removing "|" pipe at the end and then splitting the String. If you have "," as a seperator then you need to add ",$" inside replaceAll.
You could also just call the script from the terminal, outputting everything to a file, if that helps. This way:
$ /path/to/the/script.py > output.txt
This will overwrite the file. You can use >>
to append to it.
If you want errors to be logged in the file as well, use &>>
or &>
.
