Python doesn't have such types as you describe. There are two types used to represent integral values: int
, which corresponds to platform's int type in C, and long
, which is an arbitrary precision integer (i.e. it grows as needed and doesn't have an upper limit). int
s are silently converted to long
if an expression produces result which cannot be stored in int
.
I am mostly posting this in case someone comes along and is not aware that VB2005 and VB2008 have update utilities that convert older VB versions to it's format. Especially since no one bothered to point that fact out.
Points taken, but maintenance of this VB6 product is unavoidable. It would also be costly in man-hours to replace the Sheridan controls with native ones. Simply developing on a 32-bit machine would be a better alternative than doing that. I would like to install everything on Win7 64-bit ideally. – CJ7
Have you tried utilizing the code upgrade functionality of VB Express 2005+?
If not, 1. Make a copy of your code - folder and all. 2. Import the project into VB express 2005. This will activate the update wizard. 3. Debug and get the app running. 4. Create a new installer utilizing MS free tool. 5. You now have a 32 bit application with a 32 bit installer.
Until you do this, you will never know how difficult or hard it will be to update and modernize the program. It is quite possible that the wizard will update the Sheridan controls to the VB 2005 controls. Again, you will not know if it does and how well it does it until you try it.
Alternatively, stick with the 32 Bit versions of Windows 7 and 8. I have Windows 7 x64 and a program that will not run. However, the program will run in Windows 7 32 bit as well as Windows 8 RC 32 bit. Under Windows 8 RC 32, I was prompted to enable 16 bit emulation which I did and the program rand quite fine afterwords.
You may add this values to your style android:windowMinWidthMajor and android:windowMinWidthMinor
<style name="Theme_Dialog" parent="android:Theme.Holo.Dialog">
...
<item name="android:windowMinWidthMajor">97%</item>
<item name="android:windowMinWidthMinor">97%</item>
</style>
As described here: Angular NgModelController, you should provide the <input
with the required controller ngModel
<input submit-required="true" ng-model="user.Name"></input>
I don't know ruby, so I can't give you the exact syntax, but I would set a constant string with the list of acceptable characters, then use the substring operator to pick a random character out of it.
The advantage here is that if the string is supposed to be user-enterable, then you can exclude easily confused characters like l and 1 and i, 0 and O, 5 and S, etc.
You can use display: table-cell and vertical-align: bottom, on the 2 columns that you want to be aligned bottom, like so:
.bottom-column
{
float: none;
display: table-cell;
vertical-align: bottom;
}
Working example here.
Also, this might be a possible duplicate question.

None of the above worked for me (tomcat 7.0.62)... As Sensei_Shoh notes see the class above the message and add this to logging.properties. My logs were:
Jan 18, 2016 8:44:21 PM org.apache.catalina.startup.TldConfig execute
INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
so I added
org.apache.catalina.startup.TldConfig.level = FINE
in conf/logging.properties
After that I got so many "offending" files that I did not bother skipping them (and also reverted to normal logging...)
Running on Ubuntu 18.04, with VS code 1.51.0

What is blob url? Why it is used?
BLOB is just byte sequence. Browser recognize it as byte stream. It is used to get byte stream from source.
A Blob object represents a file-like object of immutable, raw data. Blobs represent data that isn't necessarily in a JavaScript-native format. The File interface is based on Blob, inheriting blob functionality and expanding it to support files on the user's system.
Can i make my own blob url on a server?
Yes you can there are serveral ways to do so for example try http://php.net/manual/en/function.ibase-blob-echo.php

You need to run Application.run()
because this method starts whole Spring Framework. Code below integrates your main()
with Spring Boot.
Application.java
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
ReconTool.java
@Component
public class ReconTool implements CommandLineRunner {
@Override
public void run(String... args) throws Exception {
main(args);
}
public static void main(String[] args) {
// Recon Logic
}
}
SpringApplication.run(ReconTool.class, args)
Because this way spring is not fully configured (no component scan etc.). Only bean defined in run() is created (ReconTool).
Example project: https://github.com/mariuszs/spring-run-magic
I use Eclipse for cross compiling and I have to add the explicit directories for some of the standard C++ libraries. Right click your project and select Properties. You'll get the dialog shown in the image. Follow the image and use the + icon to explicitly add the paths to your C++ libraries.
In my case easiest way to get browser headers was to use php. It appends headers to file and prints them to test page.
<?php
$fp = fopen('m:/temp/requests.txt', 'a');
$time = $_SERVER['REQUEST_TIME'];
fwrite($fp, $time "\n");
echo "$time.<br>";
foreach (getallheaders() as $name => $value) {
$cur_hd = "$name: $value\n";
fwrite($fp, $cur_hd);
echo "$cur_hd.<br>";
}
fwrite($fp, "***\n");
fclose($fp);
?>
tl;dr - I'm not sure that it would be possible for the .NET Core developers to supply a cross-platform GUI framework.
I feel like expecting a cross-platform GUI framework to be bundled into the official tooling (especially an old version of the tooling - you mention that you're running Visual Studio 2015 update 3) for an early version of .NET Core is a little premature.
GUI frameworks are really quite heavy, and dependent on the hardware abstractions already present on the host machine. On Windows, there is generally a single window manager (WM) and desktop environment (DE) used by most users, but on the many different distributions of Linux which are supported, there are any number of possible WMs and DEs - granted most users will either be using X-Server or Wayland in combination with KDE, GNOME or Xfce. But no Linux installation ever is the same.
The fact that the open source community can't really settle on a "standard" setup for a VM and DE means that it would be pretty difficult for the .NET Core developers to create a GUI framework which would work across all platforms and combinations of DEs and WMs.
A lot of folks here have some great suggestions (from use ASP.NET Core to builds a Web application and use a browser to listing a bunch of cross-platform frameworks). If you take a look at some of the mentioned cross platform GUI frameworks listed, you'll see how heavy they are.
However, there is light at the end of the tunnel as Miguel de Icaza showed off Xamarin running naively on Linux and macOS at .NET Conf this year (2017, if you're reading this in the future), so it might be worth trying that when it's ready.
(But you'll need to upgrade from Visual Studio 2015 to Visual Studio 2017 to access the .NET Core 2.0 features.)
You only use the M
for a numeric literal, when you cast it's just:
decimal dtot = (decimal)doubleTotal;
Note that a floating point number is not suited to keep an exact value, so if you first add numbers together and then convert to Decimal
you may get rounding errors. You may want to convert the numbers to Decimal
before adding them together, or make sure that the numbers aren't floating point numbers in the first place.
If you want case-insensitive comparison, use lower
or upper
:
if name.lower() == "jesse":
npm install sloc -g
git clone --depth 1 https://github.com/vuejs/vue/
sloc ".\vue\src" --format cli-table
rm -rf ".\vue\"
npm install sloc -g
git clone --depth 1 https://github.com/facebook/react/
sloc ".\react\src" --format cli-table
sloc supports formatting the output as a cli-table
, as json
or csv
. Regular expressions can be used to exclude files and folders (Further information on npm).
Powershell: rm -r -force ".\react\"
or on Mac/Unix: rm -rf ".\react\"
Screenshots of the executed steps (cli-table):
sloc output (no arguments):
It is also possible to get details for every file with the --details
option:
sloc ".\react\src" --format cli-table --details
In windows you can use your Command Prompcmd cmd
, in Ubuntu you can use your terminal
by typing the following command:
mongoimport -d your_database_name -c your_collection_name /path_to_json_file/json_file_name.json
then when you open your mongo shell, you will find to check your database_name when running this command:
show databases
Try using following command. I haven't tried it but I think it should work.
openssl pkcs8 -topk8 -inform PEM -outform DER -in filename -out filename -nocrypt
If you using the updated or 2018 Version for Android Studio...
compile 'com.android.support:recyclerview-v7:+'
will give you an error with following message "Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'. It will be removed at the end of 2018."
Try using this
implementation 'com.android.support:recyclerview-v7:+'
See here: Physical Vs Virtual Memory
Virtual memory is stored on the hard drive and is used when the RAM is filled. Physical memory is limited to the size of the RAM chips installed in the computer. Virtual memory is limited by the size of the hard drive, so virtual memory has the capability for more storage.
Your ProcExit label is your place where you release all the resources whether an error happened or not. For instance:
Public Sub SubA()
On Error Goto ProcError
Connection.Open
Open File for Writing
SomePreciousResource.GrabIt
ProcExit:
Connection.Close
Connection = Nothing
Close File
SomePreciousResource.Release
Exit Sub
ProcError:
MsgBox Err.Description
Resume ProcExit
End Sub
When you are inside an activity and need to go to a fragment use below
getFragmentManager().beginTransaction().replace(R.id.*TO_BE_REPLACED_LAYOUT_ID*, new tasks()).commit();
But when you are inside a fragment and need to go to a fragment then just add a getActivity().
before, so it would become
getActivity().getFragmentManager().beginTransaction().replace(R.id.*TO_BE_REPLACED_LAYOUT_ID*, new tasks()).commit();
as simple as that.
The *TO_BE_REPLACED_LAYOUT_ID*
can be the entire page of activity or a part of it, just make sure to put an id to the layout to be replaced. It is general practice to put the replaceable layout in a FrameLayout
.
Turned out there was some extra code in the AppModel that was messing things up:
in beforeFind
and afterFind
:
App::Import("Session");
$session = new CakeSession();
$sim_id = $session->read("Simulation.id");
I don't know why, but that was what the problem was. Removing those lines fixed the issue I was having.
You have to add empty option to solve it,
I also can give you one more solution but its up to you that is fine for you or not Because User select default option after selecting other options than jsFunction will be called twice.
<select onChange="jsFunction()" id="selectOpt">
<option value="1" onclick="jsFunction()">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
function jsFunction(){
var myselect = document.getElementById("selectOpt");
alert(myselect.options[myselect.selectedIndex].value);
}
New versions of Chrome have a feature called workspaces which addresses this issue. You can define which paths on your webserver correspond to which paths on your system, then edit and save with just ctrl-s.
See: http://www.html5rocks.com/en/tutorials/developertools/revolutions2013/
I have the same issue and no case resolve me the problem. The only thing that works for me, it's put on the of the Site.master file, the next:
<script src="<%= ResolveUrl("~/Scripts/jquery-1.7.1.min.js") %>" type="text/javascript"></script>
<script src="<%= ResolveUrl("~/Scripts/bootstrap/js/bootstrap.min.js") %>" type="text/javascript"></script>
With src="<%= ResolveUrl("")... the load of jQuery in the Content Pages is correct.
You can declare a dictionary inside a dictionary by nesting the {} containers:
d = {'dict1': {'foo': 1, 'bar': 2}, 'dict2': {'baz': 3, 'quux': 4}}
And then you can access the elements using the [] syntax:
print d['dict1'] # {'foo': 1, 'bar': 2}
print d['dict1']['foo'] # 1
print d['dict2']['quux'] # 4
Given the above, if you want to add another dictionary to the dictionary, it can be done like so:
d['dict3'] = {'spam': 5, 'ham': 6}
or if you prefer to add items to the internal dictionary one by one:
d['dict4'] = {}
d['dict4']['king'] = 7
d['dict4']['queen'] = 8
Try to use (focus)
and (focusout)
instead of onfocus
and onfocusout
like this : -
<input name="date" type="text" (focus)="focusFunction()" (focusout)="focusOutFunction()">
also you can use like this :-
some people prefer the on- prefix alternative, known as the canonical form:
<input name="date" type="text" on-focus="focusFunction()" on-focusout="focusOutFunction()">
Know more about event binding see here.
you have to use HostListner for your use case
Angular will invoke the decorated method when the host element emits the specified event.
@HostListener
is a decorator for the callback/event handler method
See my Update working Plunker.
Working Example Working Stackblitz
Some other events can be used in angular -
(focus)="myMethod()"
(blur)="myMethod()"
(submit)="myMethod()"
(scroll)="myMethod()"
class A{
public void methodA(){
new B().methodB();
//or
B.methodB1();
}
}
class B{
//instance method
public void methodB(){
}
//static method
public static void methodB1(){
}
}
You define var scatterSeries = [];
, and then try to parse it as a json string at console.info(JSON.parse(scatterSeries));
which obviously fails. The variable is converted to an empty string, which causes an "unexpected end of input" error when trying to parse it.
(See also the answers at What is a monad?)
A good motivation to Monads is sigfpe (Dan Piponi)'s You Could Have Invented Monads! (And Maybe You Already Have). There are a LOT of other monad tutorials, many of which misguidedly try to explain monads in "simple terms" using various analogies: this is the monad tutorial fallacy; avoid them.
As DR MacIver says in Tell us why your language sucks:
So, things I hate about Haskell:
Let’s start with the obvious. Monad tutorials. No, not monads. Specifically the tutorials. They’re endless, overblown and dear god are they tedious. Further, I’ve never seen any convincing evidence that they actually help. Read the class definition, write some code, get over the scary name.
You say you understand the Maybe monad? Good, you're on your way. Just start using other monads and sooner or later you'll understand what monads are in general.
[If you are mathematically oriented, you might want to ignore the dozens of tutorials and learn the definition, or follow lectures in category theory :) The main part of the definition is that a Monad M involves a "type constructor" that defines for each existing type "T" a new type "M T", and some ways for going back and forth between "regular" types and "M" types.]
Also, surprisingly enough, one of the best introductions to monads is actually one of the early academic papers introducing monads, Philip Wadler's Monads for functional programming. It actually has practical, non-trivial motivating examples, unlike many of the artificial tutorials out there.
In addition to Patrick's brilliant answer, for those of you who are searching for a cross-platform angular js solution, here you go:

Here is a simple way using ExtractToDirectory from System.IO.Compression.ZipFile:
Add-Type -AssemblyName System.IO.Compression.FileSystem
function Unzip
{
param([string]$zipfile, [string]$outpath)
[System.IO.Compression.ZipFile]::ExtractToDirectory($zipfile, $outpath)
}
Unzip "C:\a.zip" "C:\a"
Note that if the target folder doesn't exist, ExtractToDirectory will create it. Other caveats:

QEMU has a fantastic utility called qmeu-img that will translate between all manner of disk image formats. An article on this process is at http://thedarkmaster.wordpress.com/2007/03/12/vmware-virtual-machine-to-virtual-box-conversion-how-to/
I recall in my head that I used qemu-img to roll multiple VMDKs into one, but I don't have that computer with me to retest the process. Even if I'm wrong, the article above includes a section that describes how to convert them with your VMWare tools.
Wow, this problem is popular. It's based on a misunderstanding in the vertical-align
property. This excellent article explains it:
Understanding vertical-align
, or "How (Not) To Vertically Center Content" by Gavin Kistner.
“How to center in CSS” is a great web tool which helps to find the necessary CSS centering attributes for different situations.
In a nutshell (and to prevent link rot):
vertical-align: middle
. However, the “context” isn’t the whole parent container height, it’s the height of the text line they’re in. jsfiddle exampleabsolute
and specify its height
, margin-top
and top
position. jsfiddle exampleline-height
to fill its height. This method is quite versatile in my experience. jsfiddle exampleI know this has been answered, but here's mine just because I think case is an under-appreciated tool. (Maybe because people think it is slow, but it's at least as fast as an if, sometimes faster.)

mysql_query
function is used for executing mysql query in php. mysql_query
returns false if query execution fails.Alternatively you can try using mysql_error()
function
For e.g
$result=mysql_query($sql)
or
die(mysql_error());
In above code snippet if query execution fails then it will terminate the execution and display mysql error while execution of sql query.
One thing that happened for me is that the version of R provided by my linux distribution (R version 3.0.2 provided by Ubuntu 14.04) was too old for the latest version of the package available on CRAN (in my case, plyr
version 1.8.3 as of today). The solution was to use the packaging system of my distribution instead of trying to install from R (apt-get install r-cran-plyr
got me version 1.8.1 of plyr
). Maybe I could have tried to update R using updateR()
, but I'm afraid that doing so would interfere with my distribution's package manager.
Edit (04/08/2020): I recently had an issue with a package (XML) reportedly not available for my R version (3.6.3, latest supported on Debian stretch), after an update of the package in CRAN. It was very unexpected because I already had installed it with success before (on the same version of R and same OS).
For some reason, the package was still there, but install.packages
was only looking at the updated (and incompatible) version. The solution was to find the URL of the compatible version and force install.packages
to use it, as follows:
install.packages("https://cran.r-project.org/src/contrib/Archive/XML/XML_3.99-0.3.tar.gz", repos=NULL, type="source", ask=FALSE)

To get microseconds since the epoch, from C11 on, the portable way is to use
int timespec_get(struct timespec *ts, int base)
Unfortunately, C11 is not yet available everywhere, so as of now, the closest to portable is using one of the POSIX functions clock_gettime
or gettimeofday
(marked obsolete in POSIX.1-2008, which recommends clock_gettime
).
The code for both functions is nearly identical:
#include <stdio.h>
#include <time.h>
#include <stdint.h>
#include <inttypes.h>
int main(void) {
struct timespec tms;
/* The C11 way */
/* if (! timespec_get(&tms, TIME_UTC)) { */
/* POSIX.1-2008 way */
if (clock_gettime(CLOCK_REALTIME,&tms)) {
return -1;
}
/* seconds, multiplied with 1 million */
int64_t micros = tms.tv_sec * 1000000;
/* Add full microseconds */
micros += tms.tv_nsec/1000;
/* round up if necessary */
if (tms.tv_nsec % 1000 >= 500) {
++micros;
}
printf("Microseconds: %"PRId64"\n",micros);
return 0;
}
for (int i = 0; i < 8; i++) {
//code
}
In simplest terms
int i = 0;
if (i < 8) //code
i = i + 1; //i = 1
if (i < 8) //code
i = i + 1; //i = 2
if (i < 8) //code
i = i + 1; //i = 3
if (i < 8) //code
i = i + 1; //i = 4
if (i < 8) //code
i = i + 1; //i = 5
if (i < 8) //code
i = i + 1; //i = 6
if (i < 8) //code
i = i + 1; //i = 7
if (i < 8) //code
i = i + 1; //i = 8
if (i < 8) //code - this if won't pass
Add your MAVEN_HOME

Then import the existing Maven project to Eclipse.
Take a look at cat /proc/stat
grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}'
EDIT please read comments before copy-paste this or using this for any serious work. This was not tested nor used, it's an idea for people who do not want to install a utility or for something that works in any distribution. Some people think you can "apt-get install" anything.
NOTE: this is not the current CPU usage, but the overall CPU usage in all the cores since the system bootup. This could be very different from the current CPU usage. To get the current value top (or similar tool) must be used.
Current CPU usage can be potentially calculated with:
awk '{u=$2+$4; t=$2+$4+$5; if (NR==1){u1=u; t1=t;} else print ($2+$4-u1) * 100 / (t-t1) "%"; }' \

Python 2 uses ascii
as the default encoding for source files, which means you must specify another encoding at the top of the file to use non-ascii unicode characters in literals. Python 3 uses utf-8
as the default encoding for source files, so this is less of an issue.
See: http://docs.python.org/tutorial/interpreter.html#source-code-encoding
To enable utf-8 source encoding, this would go in one of the top two lines:
# -*- coding: utf-8 -*-
The above is in the docs, but this also works:
# coding: utf-8
Additional considerations:
The source file must be saved using the correct encoding in your text editor as well.
In Python 2, the unicode literal must have a u
before it, as in s.replace(u"Â ", u"")
But in Python 3, just use quotes. In Python 2, you can from __future__ import unicode_literals
to obtain the Python 3 behavior, but be aware this affects the entire current module.
s.replace(u"Â ", u"")
will also fail if s
is not a unicode string.
string.replace
returns a new string and does not edit in place, so make sure you're using the return value as well
Here is the best way I've found to add read-only users (using PostgreSQL 9.0 or newer):
$ sudo -upostgres psql postgres
postgres=# CREATE ROLE readonly WITH LOGIN ENCRYPTED PASSWORD '<USE_A_NICE_STRONG_PASSWORD_PLEASE';
postgres=# GRANT SELECT ON ALL TABLES IN SCHEMA public TO readonly;
Then log in to all related machines (master + read-slave(s)/hot-standby(s), etc..) and run:
$ echo "hostssl <PUT_DBNAME_HERE> <PUT_READONLY_USERNAME_HERE> 0.0.0.0/0 md5" | sudo tee -a /etc/postgresql/9.2/main/pg_hba.conf
$ sudo service postgresql reload
If your console (like your standard ubuntu console) understands ANSI color codes, you can use those.

5: C can use resources from OS, memory, etc, i.e all resources from desktop computer can be used by C. while embedded C can use limited resources, like RAM, ROM, and I/Os on an embedded processor.
I believe you should do
dice1 = arc4random_uniform(6) + 1;
to get the range 1 - 6. I don't do iOS objective C nor have I any knowledge on swift-language though. The random method should return a value between 0 and 5, and + 1 will make it a value between 1 and 6.
If you need a range between lets say 10 - 30 then just do
int random = arc4random_uniform(21) + 10;
No, you can only get to the interior color of a cell by using a Macro. I am afraid. It's really easy to do (cell.interior.color) so unless you have a requirement that restricts you from using VBA, I say go for it.
You need add parameter errors='coerce'
to function to_numeric
:
ID = pd.to_numeric(ID, errors='coerce')
If ID
is column:
df.ID = pd.to_numeric(df.ID, errors='coerce')
but non numeric are converted to NaN
, so all values are float
.
For int
need convert NaN
to some value e.g. 0
and then cast to int
:
df.ID = pd.to_numeric(df.ID, errors='coerce').fillna(0).astype(np.int64)
Sample:
df = pd.DataFrame({'ID':['4806105017087','4806105017087','CN414149']})
print (df)

For funsies... just collect the extensions in a dict, and track all of them in a folder. Then just pull the extensions you want.
import os
search = {}
for f in os.listdir(os.getcwd()):
fn, fe = os.path.splitext(f)
try:
search[fe].append(f)
except:
search[fe]=[f,]
extensions = ('.png','.jpg')
for ex in extensions:
found = search.get(ex,'')
if found:
print(found)
For MSVC you can use the linker.
link.exe /dump /linenumbers /disasm /out:foo.dis foo.dll
foo.pdb needs to be available to get symbols
You can try this for example, this code put the scrollbar at the bottom for all DIV tags
Remember: jQuery can accept a function instead the value as argument. "this" is the object treated by jQuery, the function returns the scrollHeight property of the current DIV "this" and do it for all DIV in the document.
$("div").scrollTop(function(){return this.scrollHeight})
I'm in the same situation as you, and as a beginner to Vim I originally found it a little daunting - the learning curve seems steep. From what I've learned in just a few hours I'm already feeling like I won't be able to live without it.
Here are a few links that I've found for useful Vim screencasts to show you what it's capable of.
A good bit of advice that Bram Moolenaar (benevolent dictator of Vim) gave in that last link is that it would be inefficient to try to learn every single command and function, just figure out what it is that you're doing that isn't working very well, look for a way to make it more efficient and then make it a habit.
For question #1, let's break it into two parts. First, increment any document that has "items.item_name" equal to "my_item_two". For this you'll have to use the positional "$" operator. Something like:
db.bar.update( {user_id : 123456 , "items.item_name" : "my_item_two" } ,
{$inc : {"items.$.price" : 1} } ,
false ,
true);
Note that this will only increment the first matched subdocument in any array (so if you have another document in the array with "item_name" equal to "my_item_two", it won't get incremented). But this might be what you want.
The second part is trickier. We can push a new item to an array without a "my_item_two" as follows:
db.bar.update( {user_id : 123456, "items.item_name" : {$ne : "my_item_two" }} ,
{$addToSet : {"items" : {'item_name' : "my_item_two" , 'price' : 1 }} } ,
false ,
true);
For your question #2, the answer is easier. To increment the total and the price of item_three in any document that contains "my_item_three," you can use the $inc operator on multiple fields at the same time. Something like:
db.bar.update( {"items.item_name" : {$ne : "my_item_three" }} ,
{$inc : {total : 1 , "items.$.price" : 1}} ,
false ,
true);
Edit your SVG file, add fill="currentColor"
to svg tag and make sure to remove any other fill property from the file.
For example:
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 200 139.435269383854" id="img" fill="currentColor">...
</svg>
Note that currentColor
is a keyword (not a fixed color in use).
After that, you can change the color using CSS, by setting the color
property of the element or from it's parent.
Example:
.div-with-svg-inside {
color: red;
}
I forgot to say, you must insert the SVG this way:
<svg>
<use xlink:href='/assets/file.svg#img'></use>
</svg>
Note that #img
is the id of the svg
tag inside svg file.
Another way of doing it: https://css-tricks.com/cascading-svg-fill-color/
This pointed me in the right direction, but I have a DB that originated in MSSQL 2000 and is still using the ntext
data type for the column I was replacing on. When you try to run REPLACE on that type you get this error:
Argument data type ntext is invalid for argument 1 of replace function.
The simplest fix, if your column data fits within nvarchar
, is to cast the column during replace. Borrowing the code from the accepted answer:
UPDATE YourTable
SET Column1 = REPLACE(cast(Column1 as nvarchar(max)),'a','b')
WHERE Column1 LIKE '%a%'
This worked perfectly for me. Thanks to this forum post I found for the fix. Hopefully this helps someone else!

Some clarifications (not really an answer)
In kubernetes, every pod gets assigned an IP address, and every container in the pod gets assigned that same IP address. Thus, as Alex Robinson stated in his answer, you can just use hostname -i
inside your container to get the pod IP address.
I tested with a pod running two dumb containers, and indeed hostname -i
was outputting the same IP address inside both containers. Furthermore, that IP was equivalent to the one obtained using kubectl describe pod
from outside, which validates the whole thing IMO.
However, PiersyP's answer seems more clean to me.
From kubernetes docs:
The applications in a pod all use the same network namespace (same IP and port space), and can thus “find” each other and communicate using localhost. Because of this, applications in a pod must coordinate their usage of ports. Each pod has an IP address in a flat shared networking space that has full communication with other physical computers and pods across the network.
Another piece from kubernetes docs:
Until now this document has talked about containers. In reality, Kubernetes applies IP addresses at the Pod scope - containers within a Pod share their network namespaces - including their IP address. This means that containers within a Pod can all reach each other’s ports on localhost.
Error in Events:
The application (VMware Workstation, from vendor VMware, Inc.) has the following problem: To function properly, VMware Workstation must be reinstalled after you upgrade Windows.
We can do this by setting access to JsonProperty.Access.WRITE_ONLY
while declaring the property.
@JsonProperty( value = "password", access = JsonProperty.Access.WRITE_ONLY)
@SerializedName("password")
private String password;
It passes control to the next matching route. In the example you give, for instance, you might look up the user in the database if an id
was given, and assign it to req.user
.
Below, you could have a route like:
app.get('/users', function(req, res) {
// check for and maybe do something with req.user
});
Since /users/123 will match the route in your example first, that will first check and find user 123
; then /users
can do something with the result of that.
Route middleware is a more flexible and powerful tool, though, in my opinion, since it doesn't rely on a particular URI scheme or route ordering. I'd be inclined to model the example shown like this, assuming a Users
model with an async findOne()
:
function loadUser(req, res, next) {
if (req.params.userId) {
Users.findOne({ id: req.params.userId }, function(err, user) {
if (err) {
next(new Error("Couldn't find user: " + err));
return;
}
req.user = user;
next();
});
} else {
next();
}
}
// ...
app.get('/user/:userId', loadUser, function(req, res) {
// do something with req.user
});
app.get('/users/:userId?', loadUser, function(req, res) {
// if req.user was set, it's because userId was specified (and we found the user).
});
// Pretend there's a "loadItem()" which operates similarly, but with itemId.
app.get('/item/:itemId/addTo/:userId', loadItem, loadUser, function(req, res) {
req.user.items.append(req.item.name);
});
Being able to control flow like this is pretty handy. You might want to have certain pages only be available to users with an admin flag:
/**
* Only allows the page to be accessed if the user is an admin.
* Requires use of `loadUser` middleware.
*/
function requireAdmin(req, res, next) {
if (!req.user || !req.user.admin) {
next(new Error("Permission denied."));
return;
}
next();
}
app.get('/top/secret', loadUser, requireAdmin, function(req, res) {
res.send('blahblahblah');
});
Hope this gave you some inspiration!

According to the information from @naitsirhc, I wanted to find the official API documentation. Here are my finding and some sample code.
matplotlib.Axes
object by seaborn.scatterplot()
.ax.get_legend()
will return a matplotlib.legned.Legend
instance..remove()
function to remove the legend from your plot.ax = sns.scatterplot(......)
_lg = ax.get_legend()
_lg.remove()
If you check the matplotlib.legned.Legend
API document, you won't see the .remove()
function.
The reason is that the matplotlib.legned.Legend
inherited the matplotlib.artist.Artist
. Therefore, when you call ax.get_legend().remove()
that basically call matplotlib.artist.Artist.remove()
.
In the end, you could even simplify the code into two lines.
ax = sns.scatterplot(......)
ax.get_legend().remove()
According to my interpretation of the implementation of unicode-escape
and the unicode repr
in the CPython 2.6.5 source, yes; the only difference between repr(unicode_string)
and unicode_string.encode('unicode-escape')
is the inclusion of wrapping quotes and escaping whichever quote was used.
They are both driven by the same function, unicodeescape_string
. This function takes a parameter whose sole function is to toggle the addition of the wrapping quotes and escaping of that quote.
The posted answers are very good when working with data.frame
s. However, these tasks can be pretty inefficient from a memory perspective. With large data, removing a column can take an unusually long amount of time and/or fail due to out of memory
errors. Package data.table
helps address this problem with the :=
operator:
library(data.table)
> dt <- data.table(a = 1, b = 1, c = 1)
> dt[,a:=NULL]
b c
[1,] 1 1
I should put together a bigger example to show the differences. I'll update this answer at some point with that.

I think you meant that you want to see the XML at the client, not trace it at the server. In that case, your answer is in the question I linked above, and also at How to Inspect or Modify Messages on the Client. But, since the .NET 4 version of that article is missing its C#, and the .NET 3.5 example has some confusion (if not a bug) in it, here it is expanded for your purpose.
You can intercept the message before it goes out using an IClientMessageInspector:
using System.ServiceModel.Dispatcher;
public class MyMessageInspector : IClientMessageInspector
{ }
The methods in that interface, BeforeSendRequest
and AfterReceiveReply
, give you access to the request and reply. To use the inspector, you need to add it to an IEndpointBehavior:
using System.ServiceModel.Description;
public class InspectorBehavior : IEndpointBehavior
{
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
clientRuntime.MessageInspectors.Add(new MyMessageInspector());
}
}
You can leave the other methods of that interface as empty implementations, unless you want to use their functionality, too. Read the how-to for more details.
After you instantiate the client, add the behavior to the endpoint. Using default names from the sample WCF project:
ServiceReference1.Service1Client client = new ServiceReference1.Service1Client();
client.Endpoint.Behaviors.Add(new InspectorBehavior());
client.GetData(123);
Set a breakpoint in MyMessageInspector.BeforeSendRequest()
; request.ToString()
is overloaded to show the XML.
If you are going to manipulate the messages at all, you have to work on a copy of the message. See Using the Message Class for details.
Thanks to Zach Bonham's answer at another question for finding these links.
You use INNER JOIN
to return all rows from both tables where there is a match. i.e. In the resulting table all the rows and columns will have values.
In OUTER JOIN
the resulting table may have empty columns. Outer join may be either LEFT
or RIGHT
.
LEFT OUTER JOIN
returns all the rows from the first table, even if there are no matches in the second table.
RIGHT OUTER JOIN
returns all the rows from the second table, even if there are no matches in the first table.
You can connect using a tool that I found http://www.wsdl2code.com

[proxy GetEnum];
[proxy getEnum:kTestEnumTestEnum2];

[proxy GetInt32];
[proxy GetInt64];
[proxy GetString];

let array = $('ul>li').toArray().map(item => $(item).html());

If there is an interface anywhere in the ThreadProvider hierarchy try putting the name of the Interface as the type of your service provider, eg. if you have say this structure:
public class ThreadProvider implements CustomInterface{
...
}
Then in your controller try this:
@Controller
public class ChiusuraController {
@Autowired
private CustomInterface chiusuraProvider;
}
The reason why this is happening is, in your first case when you DID NOT have ChiusuraProvider
extend ThreadProvider
Spring probably was underlying creating a CGLIB based proxy for you(to handle the @Transaction).
When you DID extend from ThreadProvider
assuming that ThreadProvider extends some interface, Spring in that case creates a Java Dynamic Proxy based Proxy, which would appear to be an implementation of that interface instead of being of ChisuraProvider
type.
If you absolutely need to use ChisuraProvider
you can try AspectJ as an alternative or force CGLIB based proxy in the case with ThreadProvider also this way:
<aop:aspectj-autoproxy proxy-target-class="true"/>
Here is some more reference on this from the Spring Reference site: http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/classic-aop-spring.html#classic-aop-pfb

Using max(date) didn't solve my problem as there is no assurance that other columns will be from the same row as the max(date) is. Instead of that this one solved my problem and sorted group by in a correct order and values of other columns are from the same row as the max date is:
SELECT model, date
FROM (SELECT * FROM doc ORDER BY date DESC) as sortedTable
GROUP BY model

If you just want to know the position of one specific user after order by field score, you can simply select all row from your table where field score is higher than the current user score. And use row number returned + 1 to know which position of this current user.
Assuming that your table is league_girl
and your primary field is id
, you can use this:
SELECT count(id) + 1 as rank from league_girl where score > <your_user_score>
See this blog article that describes the difference. Basically doing:

I had the cancelled in Firefox. Some ajax-calls working perfectly fine for me, but it failed for the coworker who actually had to use it.
When I checked this out via the Chrome tricks mentioned above, I found nothing suspicious. When checking it in firebug, it showed the 'loading' animation after the two mallicous calls, and no result tab.
The solution was mega simple: go to history, find the website, rightclick -> forget website.
Forget, not delete.
After that, no problems anymore. My guess is it has something to do with the .htaccess.

Optimized version of Jens' answere with null-safety and fallback-type.

}
if (type == null) {

}
Important: getFileExtensionFromUrl() only works with lowercase!
Bonus: Above methods as a less verbose Kotlin extension function:
fun File.getMimeType(fallback: String = "image/*"): String {
return MimeTypeMap.getFileExtensionFromUrl(toString())
?.run { MimeTypeMap.getSingleton().getMimeTypeFromExtension(toLowerCase()) }
?: fallback // You might set it to */*

C:\> move c:\users\you\somefile.txt c:\temp\newlocation.txt
and
$ mv /home/you/somefile.txt /tmp/newlocation.txt
Simply add the following style attribute in your Button
tag:
style="?android:attr/borderlessButtonStyle"
source: http://developer.android.com/guide/topics/ui/controls/button.html#Borderless
Then you can add dividers as in Karl's answer.
You need to split the string:
>>> s = 'http://www.domain.com/?s=some&two=20'
>>> s.split('&')
['http://www.domain.com/?s=some', 'two=20']
That will return a list as you can see so you can do:
>>> s2 = s.split('&')[0]
>>> print s2
http://www.domain.com/?s=some
Run this command if your ufw(Uncomplicatd Firewall) is enabled . Add for Example port 8080
$ sudo ufw allow 8080/tcp
And you can check the status by running
$ sudo ufw status

In addition to @JBNizet's answer, my general use case for ifPresent
is to combine .isPresent()
and .get()
:
Old way:
Optional opt = getIntOptional();
if(opt.isPresent()) {
Integer value = opt.get();
// do something with value
}
New way:
Optional opt = getIntOptional();
opt.ifPresent(value -> {
// do something with value
})
This, to me, is more intuitive.
See some example in http://www.sitepoint.com/understanding-sql-joins-mysql-database/
You can use 'USING' instead of 'ON' as in the query
SELECT * FROM table1 LEFT JOIN table2 USING (id);
Spring won't allow to decouple via java.util.Properties
from Spring Environment.
But Properties.load()
still works in a Spring boot application:
Properties p = new Properties();
try (InputStream is = getClass().getResourceAsStream("/my.properties")) {
p.load(is);
}
A complete solution in swift, in your view controller
// you can use your own logic to determine if you need to hide status bar
// I just put a var here for now
var hideStatusBar = false
override func preferStatusBarHidden() -> Bool {
return hideStatus
}
// in other method to manually toggle status bar
func updateUI() {
hideStatusBar = true
// call this method to update status bar
prefersStatusBarHidden()
}

Since I found this thread having the same problem, 10 YEARS later, I'll add my own solution too. I use PHP most of the time, and rather than requiring the user to press unusual buttons to refresh the page, or myself to remember to bump a version number embedded in a link, I used the filemtime() function to get the modification time of the css file (as a unix timestamp), and then use THAT number as the parameter.
$FILE_TIME = filemtime("main.css");
$CSS_LINK = "main.css?version=$FILE_TIME";
While results in a URL like:
http://example.com/blah/main.css?version=1602937140
This entirely disables caching, since every time the page is refreshed, it will believe it needs to grab the CSS file again, changed or not... but that's far less frustrating than forgetting to manually update this trick and wasting time wondering why it isn't right. You can always remove it from a production server.
If you are using plain HTML, you could probably engineer a javascript wrapper or some such, but that's probably more trouble than it's worth.
Neither main()
or void main()
are standard C. The former is allowed as it has an implicit int
return value, making it the same as int main()
. The purpose of main
's return value is to return an exit status to the operating system.
In standard C, the only valid signatures for main
are:
int main(void)
and
int main(int argc, char **argv)
The form you're using: int main()
is an old style declaration that indicates main
takes an unspecified number of arguments. Don't use it - choose one of those above.
If you need to fetch an object's property dynamically, use the getattr() function: getattr(user, "fullName")
- or to elaborate:
user = User()
property = "fullName"
name = getattr(user, property)
Otherwise just use user.fullName
.
You can return json in PHP this way:
header('Content-Type: application/json');
echo json_encode(array('foo' => 'bar'));
exit;
In large object-oriented projects, the significant reason is that C++ makes it hard to confine dependencies.
Private functions need to be listed in their respective class' public header, which makes dependencies more transitive (contagious) than they need to be:
// Ugly private dependencies
#include <map>
#include <list>
#include <chrono>
#include <stdio.h>
#include <Internal/SecretArea.h>
#include <ThirdParty/GodObjectFactory.h>
class ICantHelpButShowMyPrivatePartsSorry
{
public:
int facade(int);
private:
std::map<int, int> implementation_detail_1(std::list<int>);
std::chrono::years implementation_detail_2(FILE*);
Intern::SecretArea implementation_detail_3(const GodObjectFactory&);
};
If this pattern is blissfully repeated into dependency trees of headers, this tends to create a few "god headers" that indirectly include large portions of all headers in a project. They are as all-knowing as god objects, except that this is not apparent until you draw their inclusion trees.
This adds to compilation time in 2 ways:
Yes, there are mitigations, like forward declaration, which has perceived downsides, or the pimpl idiom, which is a nonzero cost abstraction. Even though C++ is limitless in what you can do, your peers will be wondering what you have been smoking if you go too far from how it's meant to be.
The worst part: If you think about it, the need to declare private functions in their public header is not even necessary: The moral equivalent of member functions can be, and commonly is, mimicked in C, which does not recreate this problem.
A quick and "dirty" (removes everything between < and >) solution, works with iOS >= 3.2:
-(NSString *) stringByStrippingHTML {
NSRange r;
NSString *s = [[self copy] autorelease];
while ((r = [s rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
s = [s stringByReplacingCharactersInRange:r withString:@""];
return s;
}
I have this declared as a category os NSString.
With the constructor:

arr[x] = x;

You need to use Arrow function ()=>
ES6 feature to preserve this
context within setTimeout
.
// var that = this; // no need of this line
this.messageSuccess = true;
setTimeout(()=>{ //<<<---using ()=> syntax
this.messageSuccess = false;
}, 3000);
The expressions for 1, 3 and 4 are quite similar, so you can use:
^([1-9]\d{2})([- .])(\d{3})$2(\d{4})$
Note that, depending on the language and brand of regexes used, you might need to put \2
instead of $2
or such matching might not be supported at all.
I see no good way to combine this with the format 2, apart from the obvious ^(regex for 1,3,4|regex for 2)$
which is ugly, clumsy and makes it hard to get out the parts of the numbers.
As for the area code, you can add (\+\d)?
to the beginning to capture a single-digit area code (sorry, I don't know the format of your area codes).
Look at the methods in the java.io.File class:
File file = new File("yourfileName");
String path = file.getAbsolutePath();
It's easier with the enumitem package:
\documentclass{article}
\usepackage{enumitem}
\begin{document}
Less space:
\begin{itemize}[noitemsep]
\item foo
\item bar
\item baz
\end{itemize}
Even more compact:
\begin{itemize}[noitemsep,nolistsep]
\item foo
\item bar
\item baz
\end{itemize}
\end{document}
The enumitem package provides a lot of features to customize bullets, numbering and lengths.
The paralist package provides very compact lists: compactitem, compactenum and even lists within paragraphs like inparaenum and inparaitem.

This post on the bitbucket issue tracker of virtualenvwrapper may be of interest. It is mentioned there that most of virtualenvwrapper's functions work with the venv virtual environments in Python 3.3.
I had a similar problem while setting up boilerplate code. It was reading my bundle.js file as a directory. So as stated here. EISDIR mean its a directory and not a file. To fix the issue, I deleted the file and just recreated (it was originally created automatically). If you cannot find the file (because its hidden), simply use the terminal to find and delete it.
If you have downloaded the latest Version 4.3.4 then just follow these steps.
Load the mentioned js file
<script type="text/javascript" src="/ckeditor/ckeditor.js"></script> <textarea class="ckeditor" name="editor"></textarea>
If you mean the row number after the last row that is used, you can find it with this:
Dim unusedRow As Long
unusedRow = Cells.SpecialCells(xlCellTypeLastCell).Offset(1, 0).Row
If you mean a row that happens to be blank with data after it... it gets more complicated.
Here's a function I wrote which will give you the actual row number of the first row that is blank for the provided worksheet.
Function firstBlankRow(ws As Worksheet) As Long
'returns the row # of the row after the last used row
'Or the first row with no data in it
Dim rw As Range
For Each rw In ws.UsedRange.Rows
If rw.Address = ws.Range(rw.Address).SpecialCells(xlCellTypeBlanks). _
Address Then
firstBlankRow = rw.Row
Exit For
End If
Next
If firstBlankRow = 0 Then
firstBlankRow = ws.Cells.SpecialCells(xlCellTypeLastCell). _
Offset(1, 0).Row
End If
End Function
Usage example: firstblankRow(thisworkbook.Sheets(1))
or pass any worksheet.
Edit: As ooo pointed out, this will error if there are no blank cells in your used range.
Starting with Visual Studio 2010, crystal reports is no longer installed with Visual Studio. It can be installed separately by downloading the install from SAP crystal reports website. SAP crystal reports provides two installations. The first is SAP Crystal Reports version for visual studio that is installed for working with crystal reports in visual studio. The other is SAP Crystal Reports runtime engine for .NET Framework that is installed when the application is deployed on server machine.
SAP Crystal Reports in Visual Studio 2017 is now planned for Service Pack/Support Pack 21 (as of Apr 04'2017). The current available service/support pack is 19. Service/Support Pack 21 is expected to be released in September 2017.
You can use the MSI to install on the VS PC, it won't integrate into VS so you won't be able to design reports within the VS IDE but your app will compile. There will not be any Templates either so just add the CR Viewer to the Tool bar. Upgrading an exist VS app will simply work.
So in the meantime to edit rpt files you'll need the stand-alone Crystal Reports Designer until Support Pack 21 comes along.

If you have a date in this format YYYY-MM-HH dd:mm:ss, you can actually trick php by adding a UTC at the end of your "datetime string" and use strtotime to convert it.
date_default_timezone_set('Europe/Stockholm');
print date('Y-m-d H:i:s',strtotime("2009-01-01 12:00"." UTC"))."\n";
print date('Y-m-d H:i:s',strtotime("2009-06-01 12:00"." UTC"))."\n";
This will print this:
2009-01-01 13:00:00
2009-06-01 14:00:00
And as you can see it takes care of the daylight savings time problem as well.
A little strange way to solve it.... :)
You should try this for the putting 2 array in singlr foreach loop Suppose i have 2 Array 1.$item_nm 2.$item_qty
`<?php $i=1; ?>
<table><tr><td>Sr.No</td> <td>item_nm</td> <td>item_qty</td> </tr>
@foreach (array_combine($item_nm, $item_qty) as $item_nm => $item_qty)
<tr>
<td> $i++ </td>
<td> $item_nm </td>
<td> $item_qty </td>
</tr></table>
@endforeach `
Programming Hub randomly provided a code snippet which in fact does reduce the length of an array
for (i = position_to_remove; i < length_of_array; ++i) {
inputarray[i] = inputarray[i + 1];
}
Not sure if it's behaviour that was added only later. It does the trick though.
no need for the outside events plugin...
just add an event handler to the .ui-widget-overlay div:
jQuery(document).on('click', 'body > .ui-widget-overlay', function(){
jQuery("#ui-dialog-selector-goes-here").dialog("close");
return false;
});
just make sure that whatever selector you used for the jQuery ui dialog, is also called to close it.. i.e. #ui-dialog-selector-goes-here
I finally found the solution.
npm remove webpack
npm install --save-dev @angular/cli@latest

Note: If failed, try step 4 again. It will work.
The line-continuation will fail if you have whitespace (spaces or tab characters[1]) after the backslash and before the newline. With no such whitespace, your example works fine for me:
$ cat test.sh
if ! fab --fabfile=.deploy/fabfile.py \
--forward-agent \
--disable-known-hosts deploy:$target; then
echo failed
else
echo succeeded
fi
$ alias fab=true; . ./test.sh
succeeded
$ alias fab=false; . ./test.sh
failed
Some detail promoted from the comments: the line-continuation backslash in the shell is not really a special case; it is simply an instance of the general rule that a backslash "quotes" the immediately-following character, preventing any special treatment it would normally be subject to. In this case, the next character is a newline, and the special treatment being prevented is terminating the command. Normally, a quoted character winds up included literally in the command; a backslashed newline is instead deleted entirely. But otherwise, the mechanism is the same. Most importantly, the backslash only quotes the immediately-following character; if that character is a space or tab, you just get a literal space or tab, and any subsequent newline remains unquoted.
[1] or carriage returns, for that matter, as Czechnology points out. Bash does not get along with Windows-formatted text files, not even in WSL. Or Cygwin, but at least their Bash port has added a set -o igncr

With PostgreSQL you can do it via the RETURNING keyword:
INSERT INTO mytable( field_1, field_2,... )
VALUES ( value_1, value_2 ) RETURNING anyfield
It will return the value of "anyfield". "anyfield" may be a sequence or not.
To use it with JDBC, do:
ResultSet rs = statement.executeQuery("INSERT ... RETURNING ID");
rs.next();
rs.getInt(1);
To execute your command directly from within C#, you would use the SqlCommand class.
Quick sample code using paramaterized SQL (to avoid injection attacks) might look like this:
string queryString = "SELECT tPatCulIntPatIDPk, tPatSFirstname, tPatSName, tPatDBirthday FROM [dbo].[TPatientRaw] WHERE tPatSName = @tPatSName";
string connectionString = "Server=.\PDATA_SQLEXPRESS;Database=;User Id=sa;Password=2BeChanged!;";
using (SqlConnection connection = new SqlConnection(connectionString))
{
SqlCommand command = new SqlCommand(queryString, connection);
command.Parameters.AddWithValue("@tPatSName", "Your-Parm-Value");
connection.Open();
SqlDataReader reader = command.ExecuteReader();
try
{
while (reader.Read())
{
Console.WriteLine(String.Format("{0}, {1}",
reader["tPatCulIntPatIDPk"], reader["tPatSFirstname"]));// etc
}
}
finally
{
// Always call Close when done reading.
reader.Close();
}
}
I found the following to work nicely for me. It doesn't loop and accounts for both height and width. Note that it is important to specify the PX unit when calling setTextSize on the view.
Paint paint = adjustTextSize(getPaint(), numChars, maxWidth, maxHeight);
setTextSize(TypedValue.COMPLEX_UNIT_PX,paint.getTextSize());
Here is the routine I use, passing in the getPaint() from the view. A 10 character string with a 'wide' character is used to estimate the width independent from the actual string.
private static final String text10="OOOOOOOOOO";
public static Paint adjustTextSize(Paint paint, int numCharacters, int widthPixels, int heightPixels) {
float width = paint.measureText(text10)*numCharacters/text10.length();
float newSize = (int)((widthPixels/width)*paint.getTextSize());
paint.setTextSize(newSize);
// remeasure with font size near our desired result
width = paint.measureText(text10)*numCharacters/text10.length();
newSize = (int)((widthPixels/width)*paint.getTextSize());
paint.setTextSize(newSize);
// Check height constraints
FontMetricsInt metrics = paint.getFontMetricsInt();
float textHeight = metrics.descent-metrics.ascent;
if (textHeight > heightPixels) {
newSize = (int)(newSize * (heightPixels/textHeight));
paint.setTextSize(newSize);
}
return paint;
}
Static inner class is used in the builder pattern. Static inner class can instantiate it's outer class which has only private constructor. You can not do the same with the inner class as you need to have object of the outer class created prior to accessing the inner class.
class OuterClass {
private OuterClass(int x) {
System.out.println("x: " + x);
}
static class InnerClass {
public static void test() {
OuterClass outer = new OuterClass(1);
}
}
}
public class Test {
public static void main(String[] args) {
OuterClass.InnerClass.test();
// OuterClass outer = new OuterClass(1); // It is not possible to create outer instance from outside.
}
}
This will output x: 1

Not saying this is the best approach, but it seems to work for me.
The full code may be found at: Example code at: https://github.com/dbleicher/recyclerview-grid-quickreturn
First off, add the expanded area to your cell/item layout, and make the enclosing cell layout animateLayoutChanges="true". This will ensure that the expand/collapse is animated:
<LinearLayout
android:id="@+id/llCardBack"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@android:color/white"
android:animateLayoutChanges="true"
android:padding="4dp"
android:orientation="vertical">
<TextView
android:id="@+id/tvTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center|fill_horizontal"
android:padding="10dp"
android:gravity="center"
android:background="@android:color/holo_green_dark"
android:text="This is a long title to show wrapping of text in the view."
android:textColor="@android:color/white"
android:textSize="16sp" />
<TextView
android:id="@+id/tvSubTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center|fill_horizontal"
android:background="@android:color/holo_purple"
android:padding="6dp"
android:text="My subtitle..."
android:textColor="@android:color/white"
android:textSize="12sp" />
<LinearLayout
android:id="@+id/llExpandArea"
android:visibility="gone"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="6dp"
android:text="Item One" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="6dp"
android:text="Item Two" />
</LinearLayout>
</LinearLayout>
Then, make your RV Adapter class implement View.OnClickListener so that you can act on the item being clicked. Add an int field to hold the position of the one expanded view, and initialize it to a negative value:
private int expandedPosition = -1;
Finally, implement your ViewHolder, onBindViewHolder() methods and override the onClick() method. You will expand the view in onBindViewHolder if it's position is equal to "expandedPosition", and hide it if not. You set the value of expandedPosition in the onClick listener:
@Override
public void onBindViewHolder(RVAdapter.ViewHolder holder, int position) {
int colorIndex = randy.nextInt(bgColors.length);
holder.tvTitle.setText(mDataset.get(position));
holder.tvTitle.setBackgroundColor(bgColors[colorIndex]);
holder.tvSubTitle.setBackgroundColor(sbgColors[colorIndex]);
if (position == expandedPosition) {
holder.llExpandArea.setVisibility(View.VISIBLE);
} else {
holder.llExpandArea.setVisibility(View.GONE);
}
}
@Override
public void onClick(View view) {
ViewHolder holder = (ViewHolder) view.getTag();
String theString = mDataset.get(holder.getPosition());
// Check for an expanded view, collapse if you find one
if (expandedPosition >= 0) {
int prev = expandedPosition;
notifyItemChanged(prev);
}
// Set the current position to "expanded"
expandedPosition = holder.getPosition();
notifyItemChanged(expandedPosition);
Toast.makeText(mContext, "Clicked: "+theString, Toast.LENGTH_SHORT).show();
}
/**
* Create a ViewHolder to represent your cell layout
* and data element structure
*/
public static class ViewHolder extends RecyclerView.ViewHolder {
TextView tvTitle;
TextView tvSubTitle;
LinearLayout llExpandArea;
public ViewHolder(View itemView) {
super(itemView);
tvTitle = (TextView) itemView.findViewById(R.id.tvTitle);
tvSubTitle = (TextView) itemView.findViewById(R.id.tvSubTitle);
llExpandArea = (LinearLayout) itemView.findViewById(R.id.llExpandArea);
}
}
This should expand only one item at a time, using the system-default animation for the layout change. At least it works for me. Hope it helps.
init = extendFunction(init, function(args) {
doSomethingHereToo();
});
But in your specific case, it's easier to extend the global onload function:
extendFunction('onload', function(args) {
doSomethingHereToo();
});
I actually really like your question, it's making me think about different use cases.
For javascript events, you really want to add and remove handlers - but for extendFunction, how could you later remove functionality? I could easily add a .revert method to extended functions, so init = init.revert()
would return the original function. Obviously this could lead to some pretty bad code, but perhaps it lets you get something done without touching a foreign part of the codebase.
The last parameter to the rgba()
function is the "alpha" or "opacity" parameter. If you set it to 0
it will mean "completely transparent", and the first three parameters (the red
, green
, and blue
channels) won't matter because you won't be able to see the color anyway.
With that in mind, I would choose rgba(0, 0, 0, 0)
because:
You could avoid the rgba
model altogether and use the transparent
keyword instead, which according to w3.org, is equivalent to "transparent black" and should compute to rgba(0, 0, 0, 0)
. For example:
h1 {
background-color: transparent;
}
This saves you yet another couple bytes while your intentions of using transparency are obvious (in case one is unfamiliar with RGBA).
As of CSS3, you can use the transparent
keyword for any CSS property that accepts a color.
If you want to print output of anything in Bash without end of line, you echo it with the -n
switch.
If you have it in a variable already, then echo it with the trailing newline cropped:
$ testvar=$(wc -l < log.txt)
$ echo -n $testvar
Or you can do it in one line, instead:
$ echo -n $(wc -l < log.txt)
Another good way to understand it:
var foo = {}
/*
foo.constructor is Object, so foo.constructor.prototype is actually
Object.prototype; Object.prototype in return is what foo.__proto__ links to.
*/
console.log(foo.constructor.prototype === foo.__proto__);
// this proves what the above comment proclaims: Both statements evaluate to true.
console.log(foo.__proto__ === Object.prototype);
console.log(foo.constructor.prototype === Object.prototype);
Only after IE11 __proto__
is supported. Before that version, such as IE9, you could use the constructor
to get the __proto__
.
I have found this to be the easiest way by far.
Use this method:
public static String getJSON(String url) {
HttpsURLConnection con = null;
try {
URL u = new URL(url);
con = (HttpsURLConnection) u.openConnection();
con.connect();
BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));
StringBuilder sb = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
sb.append(line + "\n");
}
br.close();
return sb.toString();
} catch (MalformedURLException ex) {
ex.printStackTrace();
} catch (IOException ex) {
ex.printStackTrace();
} finally {
if (con != null) {
try {
con.disconnect();
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
return null;
}
And use it like this:
String json = getJSON(url);
JSONObject obj;
try {
obj = new JSONObject(json);
JSONArray results_arr = obj.getJSONArray("results");
final int n = results_arr.length();
for (int i = 0; i < n; ++i) {
// get the place id of each object in JSON (Google Search API)
String place_id = results_arr.getJSONObject(i).getString("place_id");
}
}
Remove the function and check the output of:
var_dump(function_exists('parseDate'));
In which case, change the name of the function.
If you get false, you're including the file with that function twice, replace :
include
by
include_once
And replace :
require
by
require_once

Did you import it? Importing matplotlib
is not enough.
>>> import matplotlib
>>> matplotlib.pyplot
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'pyplot'
but
>>> import matplotlib.pyplot
>>> matplotlib.pyplot
works.
pyplot is a submodule of matplotlib and not immediately imported when you import matplotlib.
The most common form of importing pyplot is
import matplotlib.pyplot as plt
Thus, your statements won't be too long, e.g.
plt.plot([1,2,3,4,5])
instead of
matplotlib.pyplot.plot([1,2,3,4,5])
And: pyplot
is not a function, it's a module! So don't call it, use the functions defined inside this module instead. See my example above

H.264 is a new standard for video compression which has more advanced compression methods than the basic MPEG-4 compression. One of the advantages of H.264 is the high compression rate. It is about 1.5 to 2 times more efficient than MPEG-4 encoding. This high compression rate makes it possible to record more information on the same hard disk.
The image quality is also better and playback is more fluent than with basic MPEG-4 compression. The most interesting feature however is the lower bit-rate required for network transmission.
So the 3 main advantages of H.264 over MPEG-4 compression are:
- Small file size for longer recording time and better network transmission.
- Fluent and better video quality for real time playback
- More efficient mobile surveillance applicationH264 is now enshrined in MPEG4 as part 10 also known as AVC
Refer to: http://www.velleman.eu/downloads/3/h264_vs_mpeg4_en.pdf

FragmentStatePagerAdapter:
with FragmentStatePagerAdapter
,your unneeded fragment is
destroyed.A transaction is committed to completely remove the
fragment from your activity's FragmentManager
.
The state in FragmentStatePagerAdapter
comes from the fact that it
will save out your fragment's Bundle
from savedInstanceState
when
it is destroyed.When the user navigates back,the new fragment will be
restored using the fragment's state.
FragmentPagerAdapter:
By comparision FragmentPagerAdapter
does nothing of the kind.When
the fragment is no longer needed.FragmentPagerAdapter
calls
detach(Fragment)
on the transaction instead of remove(Fragment)
.
This destroy's the fragment's view but leaves the fragment's instance
alive in the FragmentManager
.so the fragments created in the
FragmentPagerAdapter
are never destroyed.
After making no changes to a production server we began receiving this error. After trying several different things and thinking that perhaps there were DNS issues, restarting IIS fixed the issue (restarting only the site did not fix the issue). It likely won't work for everyone but if we tried that first it would have saved a lot of time.
it turns out that I got this error because my requested module is not bundled in the minification prosses
due to path misspelling
so make sure that your module exists in minified js file (do search for a word within it to be sure)
I tried posting this as a comment, but couldn't get the columns to display right (as per your question).
You are asking for:
A B
C D
E
... but the answer accepted as the solution will return:
A D
B E
C
... so either the answer is incorrect or the question is.
A very simple solution would be to set the width of your <ul>
and then float and set the width of your <li>
items like so
<ul>
<li>A</li>
<li>B</li>
<li>C</li>
<li>D</li>
<li>E</li>
</ul>
ul{
width:210px;
}
li{
background:green;
float:left;
height:100px;
margin:0 10px 10px 0;
width:100px;
}
li:nth-child(even){
margin-right:0;
}

If your question is wrong, then the previous answers apply (with a JS fix for lacking IE support).
You will find multiple different methods that people use and they each have there own place.

If in your php.ini attribute short_open_tag = true
(this is normally found on line 141
of the default php.ini file) you can replace your php open tag from <?php
to <?
. This is not advised as most live server environments have this turned off (including many CMS's like Drupal, WordPress and Joomla). I have already tested short hand open tags in Drupal and confirmed that it will break your site, so stick with <?php
. short_open_tag
is not on by default in all server configurations and must not be assumed as such when developing for unknown server configurations. Many hosting companies have short_open_tag
turned off.
A quick search of short_open_tag
in stackExchange shows 830 results. https://stackoverflow.com/search?q=short_open_tag
That's a lot of people having problems with something they should just not play with.
with some server environments and applications, short hand php open tags will still crash your code even with short_open_tag
set to true
.
short_open_tag
will be removed in PHP6 so don't use short hand tags.
all future PHP versions will be dropping short_open_tag
"It's been recommended for several years that you not use the short tag "short cut" and instead to use the full tag combination. With the wide spread use of XML and use of these tags by other languages, the server can become easily confused and end up parsing the wrong code in the wrong context. But because this short cut has been a feature for such a long time, it's currently still supported for backwards compatibility, but we recommend you don't use them." – Jelmer Sep 25 '12 at 9:00 php: "short_open_tag = On" not working
and
Normally you write PHP like so: . However if allow_short_tags directive is enabled you're able to use: . Also sort tags provides extra syntax: which is equal to .
Short tags might seem cool but they're not. They causes only more problems. Oh... and IIRC they'll be removed from PHP6. Crozin answered Aug 24 '10 at 22:12 php short_open_tag problem
and
To answer the why part, I'd quote Zend PHP 5 certification guide: "Short tags were, for a time, the standard in the PHP world; however, they do have the major drawback of conflicting with XML headers and, therefore, have somewhat fallen by the wayside." – Fluffy Apr 13 '11 at 14:40 Are PHP short tags acceptable to use?
You may also see people use the following example:
<?php if($first_condition){ ?>
/*$first_condition is true*/
<?php }else if ($second_condition){ ?>
/*$first_condition is false and $second_condition is true*/
<?php }else{ ?>
/*$first_condition and $second_condition are false*/
<?php } ?>
This will work but it is highly frowned upon as it's not considered as legible and is not what you would use this format for. If you had a PHP file where you had a block of PHP code that didn't have embedded tags inside, then you would use the bracket format.
The following example shows when to use the bracket method
<?php
if($first_condition){
/*$first_condition is true*/
}else if ($second_condition){
/*$first_condition is false and $second_condition is true*/
}else{
/*$first_condition and $second_condition are false*/
}
?>
If you're doing this code for yourself you can do what you like, but if your working with a team at a job it is advised to use the correct format for the correct circumstance. If you use brackets in embedded html/php scripts that is a good way to get fired, as no one will want to clean up your code after you. IT bosses will care about code legibility and college professors grade on legibility.
UPDATE
based on comments from duskwuff its still unclear if shorthand is discouraged (by the php standards) or not. I'll update this answer as I get more information. But based on many documents found on the web about shorthand being bad for portability. I would still personally not use it as it gives no advantage and you must rely on a setting being on that is not on for every web host.
Use code:
File file = new File("input.txt");
BufferedInputStream bin = new BufferedInputStream(new FileInputStream(
file));
byte[] buffer = new byte[(int) file.length()];
bin.read(buffer);
String fileStr = new String(buffer);
fileStr contains output in String.
Calling presentViewController
presents the view controller modally, outside the existing navigation stack; it is not contained by your UINavigationController or any other. If you want your new view controller to have a navigation bar, you have two main options:
Option 1. Push the new view controller onto your existing navigation stack, rather than presenting it modally:
let VC1 = self.storyboard!.instantiateViewControllerWithIdentifier("MyViewController") as! ViewController
self.navigationController!.pushViewController(VC1, animated: true)
Option 2. Embed your new view controller into a new navigation controller and present the new navigation controller modally:
let VC1 = self.storyboard!.instantiateViewControllerWithIdentifier("MyViewController") as! ViewController
let navController = UINavigationController(rootViewController: VC1) // Creating a navigation controller with VC1 at the root of the navigation stack.
self.present(navController, animated:true, completion: nil)
Bear in mind that this option won't automatically include a "back" button. You'll have to build in a close mechanism yourself.
Which one is best for you is a human interface design question, but it's normally clear what makes the most sense.
Try something like this - it works for the cases you have mentioned.
select * from tbl
where answer like '%[0-9]%'
and answer not like '%[:]%'
and answer not like '%[A-Z]%'
Is there a way to have placeholders, like ? for column names? For example SELECT ? FROM TABLEA GROUP BY ?
Use dynamic query as below:
String queryString = "SELECT "+ colName+ " FROM TABLEA GROUP BY "+ colName;
If I want to simply run the above query and get a List what is the best way?
List<String> data = getJdbcTemplate().query(query, new RowMapper<String>(){
public String mapRow(ResultSet rs, int rowNum)
throws SQLException {
return rs.getString(1);
}
});
EDIT: To Stop SQL Injection, check for non word characters in the colName as :
Pattern pattern = Pattern.compile("\\W");
if(pattern.matcher(str).find()){
//throw exception as invalid column name
}
Just if someone is having this issue and hadn't done list[index, sub-index]
, you could be having the problem because you're missing a comma between two arrays in an array of arrays (It happened to me).
Well in fact TryGetValue is faster. How much faster? It depends on the dataset at hand. When you call the Contains method, Dictionary does an internal search to find its index. If it returns true, you need another index search to get the actual value. When you use TryGetValue, it searches only once for the index and if found, it assigns the value to your variable.
Edit:
Ok, I understand your confusion so let me elaborate:
Case 1:
if (myDict.Contains(someKey))
someVal = myDict[someKey];
In this case there are 2 calls to FindEntry, one to check if the key exists and one to retrieve it
Case 2:
myDict.TryGetValue(somekey, out someVal)
In this case there is only one call to FindKey because the resulting index is kept for the actual retrieval in the same method.
Somewhere you will need to set a fixed height, instead of using auto everywhere. You will find that if you set a fixed height on your content and/or container, then using auto for things inside it will work.
Also, your boxes will still expand height-wise with more content in, even though you have set a height for it - so don't worry about that :)
#container {
height:500px;
min-height:500px;
}
If your shell supports it, would something like this work ?
javac com/**/*.java
If your shell does not support **
, then maybe
javac com/*/*/*.java
works (for all packages with 3 components - adapt for more or less).
Something like this may be:
String str = "abcdefghijklmnopqrtuvwxyz";
if (str.length() > 8)
str = str.substring(0, 8) + "...";
Many answers focus on how to make your solution work, while very few suggest that your solution is a very bad approach. If you really want to "practice to learn", why not practice using good solutions? Hardcoding your password is learning the wrong approach!
If what you really want is a password-less mount
for that volume, maybe sudo
isn't needed at all! So may I suggest other approaches?
Use /etc/fstab
as mensi suggested. Use options user
and noauto
to let regular users mount that volume.
Use Polkit
for passwordless actions: Configure a .policy
file for your script with <allow_any>yes</allow_any>
and drop at /usr/share/polkit-1/actions
Edit /etc/sudoers
to allow your user to use sudo
without typing your password. As @Anders suggested, you can restrict such usage to specific commands, thus avoiding unlimited passwordless root priviledges in your account. See this answer for more details on /etc/sudoers
.
All the above allow passwordless root privilege, none require you to hardcode your password. Choose any approach and I can explain it in more detail.
As for why it is a very bad idea to hardcode passwords, here are a few good links for further reading:
When you set a string variable, it doesn't save quotes of it, they are a part of its definition. so you don't need to use :1
There is another way...
header('Content-Type: text/plain; charset=utf-8');
This makes the whole page served as plain text... better is htmlspecialchars...
Hope this helps...
<input ... checked />
<input ... checked="checked" />
Those are equally valid. And in JavaScript:
input.checked = true;
input.setAttribute("checked");
input.setAttribute("checked","checked");
To be able to create a relation, the table Storage Engine must be InnoDB. You can edit in Operations tab.
Then, you need to be sure that the id column in your main table has been indexed. It should appear at Index section in Structure tab.
Finally, you could see the option Relations View in Structure tab. When edditing, you will be able to select the parent column in foreign table to create the relation.
See attachments. I hope this could be useful for anyone.
You can add a TOC manually with Markdown and HTML. Here's how I have been adding:
## TOC:
* [First Bullet Header](#first-bullet)
* [Second Bullet Header](#second-bullet)
## First Bullet Header <a class="anchor" id="first-bullet"></a>
code blocks...
## Second Bullet Header <a class="anchor" id="second-bullet"></a>
code blocks...
It may not be the best approach, but it works. Hope this helps.
First create helpers.php inside App\Http directory. Then add the following code inside the composer.json
"autoload": {
"classmap": [
"database"
],
"files": [
"app/Http/helpers.php"
],
"psr-4": {
"App\\": "app/"
}
},
Next run the following command
composer dump-autoload
Now you can define your custom function inside the helpers.php file.
The URL is relative to the location of the CSS file, so this should work for you:
url('../../images/image.jpg')
The relative URL goes two folders back, and then to the images
folder - it should work for both cases, as long as the structure is the same.
From https://www.w3.org/TR/CSS1/#url:
Partial URLs are interpreted relative to the source of the style sheet, not relative to the document
There's no need for the outer try in your example, so you can at least go down from 3 to 2, and also you don't need closing ;
at the end of the resource list. The advantage of using two try blocks is that all of your code is present up front so you don't have to refer to a separate method:
public List<User> getUser(int userId) {
String sql = "SELECT id, username FROM users WHERE id = ?";
List<User> users = new ArrayList<>();
try (Connection con = DriverManager.getConnection(myConnectionURL);
PreparedStatement ps = con.prepareStatement(sql)) {
ps.setInt(1, userId);
try (ResultSet rs = ps.executeQuery()) {
while(rs.next()) {
users.add(new User(rs.getInt("id"), rs.getString("name")));
}
}
} catch (SQLException e) {
e.printStackTrace();
}
return users;

Whilst you can of course use the base64
module, you can also to use the codecs
module (referred to in your error message) for binary encodings (meaning non-standard & non-text encodings).
For example:
import codecs
my_bytes = b"Hello World!"
codecs.encode(my_bytes, "base64")
codecs.encode(my_bytes, "hex")
codecs.encode(my_bytes, "zip")
codecs.encode(my_bytes, "bz2")
This can come in useful for large data as you can chain them to get compressed and json-serializable values:
my_large_bytes = my_bytes * 10000
codecs.decode(
codecs.encode(
codecs.encode(
my_large_bytes,
"zip"
),
"base64"),
"utf8"
)

Unless you write your own Homescreen launcher or use an existing one from Goolge Play, there's "no way" to resize icons.
Well, "no way" does not mean its impossible:
You can use:
Bulk collect along with FOR ALL that is called Bulk binding
.
Because PL/SQL forall
operator speeds 30x faster for simple table inserts.
BULK_COLLECT
and Oracle FORALL
together these two features are known as Bulk Binding
. Bulk Binds are a PL/SQL technique where, instead of multiple individual SELECT
, INSERT
, UPDATE
or DELETE
statements are executed to retrieve from, or store data in, at table, all of the operations are carried out at once, in bulk. This avoids the context-switching you get when the PL/SQL engine has to pass over to the SQL engine, then back to the PL/SQL engine, and so on, when you individually access rows one at a time. To do bulk binds with INSERT
, UPDATE
, and DELETE
statements, you enclose the SQL statement within a PL/SQL FORALL
statement. To do bulk binds with SELECT
statements, you include the BULK COLLECT
clause in the SELECT
statement instead of using INTO
.
It improves performance.
create .env using command!
composer run post-root-package-install or sudo composer run post-root-package-install
You should use the OpenFileDialog class like this
Dim fd As OpenFileDialog = New OpenFileDialog()
Dim strFileName As String
fd.Title = "Open File Dialog"
fd.InitialDirectory = "C:\"
fd.Filter = "All files (*.*)|*.*|All files (*.*)|*.*"
fd.FilterIndex = 2
fd.RestoreDirectory = True
If fd.ShowDialog() = DialogResult.OK Then
strFileName = fd.FileName
End If
Then you can use the File class.
