Given this example url:
http://www.example.com/some-dir/yourpage.php?q=bogus&n=10
$_SERVER['REQUEST_URI']
will give you:
/some-dir/yourpage.php?q=bogus&n=10
Whereas $_GET['q']
will give you:
bogus
In other words, $_SERVER['REQUEST_URI']
will hold the full request path including the querystring. And $_GET['q']
will give you the value of parameter q
in the querystring.
Try this:
String numberStr = "3.5";
Float number = null;
try {
number = Float.parseFloat(numberStr);
} catch (NumberFormatException e) {
System.out.println("numberStr is not a number");
}
This works like a clock for me:
methods: {
hasHistory () { return window.history.length > 2 }
}
Then, in the template:
<button
type="button"
@click="hasHistory()
? $router.go(-1)
: $router.push('/')" class="my-5 btn btn-outline-success">«
Back
</button>
Add to app.module.ts
import {MatIconModule} from '@angular/material/icon';
& link in your global index.html.
You can use concat:
In [11]: pd.concat([df1['c'], df2['c']], axis=1, keys=['df1', 'df2'])
Out[11]:
df1 df2
2014-01-01 NaN -0.978535
2014-01-02 -0.106510 -0.519239
2014-01-03 -0.846100 -0.313153
2014-01-04 -0.014253 -1.040702

2014-01-08 NaN -1.791899
[8 rows x 2 columns]
The axis argument determines the way the DataFrames are stacked:
df1 = pd.DataFrame([1, 2, 3])
df2 = pd.DataFrame(['a', 'b', 'c'])
pd.concat([df1, df2], axis=0)
0
0 1

When you want a flex item to occupy an entire row, set it to width: 100%
or flex-basis: 100%
, and enable wrap
on the container.
The item now consumes all available space. Siblings are forced on to other rows.
.parent {
display: flex;
flex-wrap: wrap;
}
#range, #text {
flex: 1;
}
.error {
flex: 0 0 100%; /* flex-grow, flex-shrink, flex-basis */
border: 1px dashed black;
}
_x000D_
<div class="parent">
<input type="range" id="range">
<input type="text" id="text">
<label class="error">Error message (takes full width)</label>
</div>
_x000D_
More info: The initial value of the flex-wrap
property is nowrap
, which means that all items will line up in a row. MDN
ViewGroup class provides API for child views management in run-time, allowing to add/remove views as well.

Stackoverflow uses such function to determine the age of a user.
The given answer is
DateTime now = DateTime.Today;
int age = now.Year - bday.Year;
if (now < bday.AddYears(age)) age--;
So your helper method would look like
public static string Age(this HtmlHelper helper, DateTime birthday)
{
DateTime now = DateTime.Today;
int age = now.Year - birthday.Year;
if (now < birthday.AddYears(age)) age--;
return age.ToString();
}
Today, I use a different version of this function to include a date of reference. This allow me to get the age of someone at a future date or in the past. This is used for our reservation system, where the age in the future is needed.
public static int GetAge(DateTime reference, DateTime birthday)
{
int age = reference.Year - birthday.Year;
if (reference < birthday.AddYears(age)) age--;
return age;
}
If you want today's date without the time, just use Date.today
i got solution what you are getting as per imp help=y
it is mentioned that imp is only valid for TRANSPORT_TABLESPACE
as below:
Keyword Description (Default) Keyword Description (Default)
--------------------------------------------------------------------------
USERID username/password FULL import entire file (N)
BUFFER size of data buffer FROMUSER list of owner usernames
FILE input files (EXPDAT.DMP) TOUSER list of usernames
SHOW just list file contents (N) TABLES list of table names
IGNORE ignore create errors (N) RECORDLENGTH length of IO record
GRANTS import grants (Y) INCTYPE incremental import type
INDEXES import indexes (Y) COMMIT commit array insert (N)
ROWS import data rows (Y) PARFILE parameter filename
LOG log file of screen output CONSTRAINTS import constraints (Y)
DESTROY overwrite tablespace data file (N)
INDEXFILE write table/index info to specified file
SKIP_UNUSABLE_INDEXES skip maintenance of unusable indexes (N)
FEEDBACK display progress every x rows(0)
TOID_NOVALIDATE skip validation of specified type ids
FILESIZE maximum size of each dump file
STATISTICS import precomputed statistics (always)
RESUMABLE suspend when a space related error is encountered(N)
RESUMABLE_NAME text string used to identify resumable statement
RESUMABLE_TIMEOUT wait time for RESUMABLE
COMPILE compile procedures, packages, and functions (Y)
STREAMS_CONFIGURATION import streams general metadata (Y)
STREAMS_INSTANTIATION import streams instantiation metadata (N)
DATA_ONLY import only data (N)
The following keywords only apply to transportable tablespaces
TRANSPORT_TABLESPACE import transportable tablespace metadata (N)
TABLESPACES tablespaces to be transported into database
DATAFILES datafiles to be transported into database
TTS_OWNERS users that own data in the transportable tablespace set
So, Please create table space for your user:
CREATE TABLESPACE <tablespace name> DATAFILE <path to save, example: 'C:\ORACLEXE\APP\ORACLE\ORADATA\XE\ABC.dbf'> SIZE 100M AUTOEXTEND ON NEXT 100M MAXSIZE 10G EXTENT MANAGEMENT LOCAL UNIFORM SIZE 1M;
First, you show that it lies in NP at all.
Then you find another problem that you already know is NP complete and show how you polynomially reduce NP Hard problem to your problem.
It's also easy to use Alien as a libc/msvcrt wrapper:
> luarocks install alien
Then from lua:
require 'alien'
if alien.platform == "windows" then
-- untested!!
libc = alien.load("msvcrt.dll")
else
libc = alien.default
end
usleep = libc.usleep
usleep:types('int', 'uint')
function sleep(ms)
while ms > 1000 do
usleep(1000)
ms = ms - 1000
end
usleep(1000 * ms)
end
print('hello')
sleep(500) -- sleep 500 ms
print('world')
Caveat lector: I haven't tried this on MSWindows; I don't even know if msvcrt has a usleep()

It sounds like you would benefit from using an automation utility. If you were using a windows PC I would recommend AutoHotkey. I haven't used automation utilities on a Mac, but this Ask Different post has several suggestions, though none appear to be free.
This is not a VBA solution. These macros run outside of Excel and can interact with programs using keyboard strokes, mouse movements and clicks.
Basically you record or write a simple automation macro that waits for the Excel "Save As" dialogue box to become active, hits enter/return to complete the save action and then waits for the "Save As" window to close. You can set it to run in a continuous loop until you manually end the macro.
Here's a simple version of a Windows AutoHotkey script that would accomplish what you are attempting to do on a Mac. It should give you an idea of the logic involved.
; ' Infinite loop. End the macro by closing the program from the Windows taskbar.
Loop {
; ' Wait for ANY "Save As" dialogue box in any program.
; ' BE CAREFUL!
; ' Ignore the "Confirm Save As" dialogue if attempt is made
; ' to overwrite an existing file.
WinWait, Save As,,, Confirm Save As
IfWinNotActive, Save As,,, Confirm Save As
WinActivate, Save As,,, Confirm Save As
WinWaitActive, Save As,,, Confirm Save As
sleep, 250 ; ' 0.25 second delay
Send, {ENTER} ; ' Save the Excel file.
; ' Wait for the "Save As" dialogue box to close.
WinWaitClose, Save As,,, Confirm Save As
}
What you are looking for is disabled="true". Here is an example:
<textarea class="customPayload" disabled="true" *ngIf="!showSpinner"></textarea>
UPDATE users SET username='&username', password='&password' where id='&id'
This query will ask you to enter the username,password and id dynamically
The string is basically bounded from the place where it is pointed to (char *ptrChar;
), to the null character (\0
).
The char *ptrChar;
actually points to the beginning of the string (char array), and thus that is the pointer to that string,
so when you do like ptrChar[x]
for example, you actually access the memory location x times after the beginning of the char (aka from where ptrChar is pointing to).
Check the errorlevel
in an if
statement, and then exit /b
(exit the batch file only, not the entire cmd.exe process) for values other than 0.
same-executable-over-and-over.exe /with different "parameters"
if %errorlevel% neq 0 exit /b %errorlevel%
If you want the value of the errorlevel to propagate outside of your batch file
if %errorlevel% neq 0 exit /b %errorlevel%
but if this is inside a for
it gets a bit tricky. You'll need something more like:
setlocal enabledelayedexpansion
for %%f in (C:\Windows\*) do (
same-executable-over-and-over.exe /with different "parameters"
if !errorlevel! neq 0 exit /b !errorlevel!
)
Edit: You have to check the error after each command. There's no global "on error goto" type of construct in cmd.exe/command.com batch. I've also updated my code per CodeMonkey, although I've never encountered a negative errorlevel in any of my batch-hacking on XP or Vista.
This error also occurs when you try to move the whole project directory to other path. And you happened to run the following commands below BEFORE you move.
php artisan optimize --force
php artisan config:cache
php artisan route:cache
Mine error message shows like this
As you can see the old path was written in the compiled.php. So, to fix the problem. Simply run the same command AGAIN under the project folder in your new folder location.
php artisan optimize --force
php artisan config:cache
php artisan route:cache
Hope this helps.
Just to complete the existing answers, I'd suggest using select instead of nonblocking sockets. The point is that nonblocking sockets complicate stuff (except perhaps sending), so I'd say there is no reason to use them at all. If you regularly have the problem that your app is blocked waiting for IO, I would also consider doing the IO in a separate thread in the background.
A new take on this question would involve the use of Faker which you can install easily with pip
.
from faker import Factory
#----------------------------------------------------------------------
def create_values(fake):
""""""
print fake.boolean(chance_of_getting_true=50) # True
print fake.random_int(min=0, max=1) # 1
if __name__ == "__main__":
fake = Factory.create()
create_values(fake)
pandas.Series.astype
You can do something like this :
weather["Temp"] = weather.Temp.astype(float)
You can also use pd.to_numeric
that will convert the column from object to float
Example :
s = pd.Series(['apple', '1.0', '2', -3])
print(pd.to_numeric(s, errors='ignore'))
print("=========================")
print(pd.to_numeric(s, errors='coerce'))
Output:
0 apple
1 1.0
2 2
3 -3
=========================
dtype: object
0 NaN
1 1.0
2 2.0
3 -3.0
dtype: float64
In your case you can do something like this:
weather["Temp"] = pd.to_numeric(weather.Temp, errors='coerce')
convert_objects
Example is as follows
>> pd.Series([1,2,3,4,'.']).convert_objects(convert_numeric=True)
0 1
1 2
2 3
3 4
4 NaN
dtype: float64
You can use this as follows:
weather["Temp"] = weather.Temp.convert_objects(convert_numeric=True)
NaN
... so be careful while using it.I know this is an old question but if you're still programming, in python 3 these days... I have actually found that if it is a string, then there is a really easy way to do this:
>>> spam.upper
<built-in method upper of str object at 0x1042e4830>
>>> spam.upper()
'YO I NEED HELP!'
>>> id(spam)
4365109296
string conversion does not affect location in memory either:
>>> spam = {437 : 'passphrase'}
>>> object.__repr__(spam)
'<dict object at 0x1043313f0>'
>>> str(spam)
"{437: 'passphrase'}"
>>> object.__repr__(spam)
'<dict object at 0x1043313f0>'
Looking at the Eclipse plugin docs I found some useful tasks that rebuilt my classpath and updated the required dependencies.
gradle cleanEclipse
to clean the Eclipse configuration completely. If this doesn;t work you may try more specific tasks:
gradle cleanEclipseProject
to remove the .project filegradle cleanEclipseClasspath
to empty the project's classpathgradle eclipse
to rebuild the Eclipse configurationDepending on whether you want to change all the identical links to something else or you want control over just the ones in a given section of the page or each one individually, you could do one of these.
Change all links to Google so they point to Google Maps:
<a href="http://www.google.com">
$("a[href='http://www.google.com/']").attr('href',
'http://maps.google.com/');
To change links in a given section, add the container div's class to the selector. This example will change the Google link in the content, but not in the footer:
<div class="content">
<p>...link to <a href="http://www.google.com/">Google</a>
in the content...</p>
</div>
<div class="footer">
Links: <a href="http://www.google.com/">Google</a>
</div>
$(".content a[href='http://www.google.com/']").attr('href',
'http://maps.google.com/');
To change individual links regardless of where they fall in the document, add an id to the link and then add that id to the selector. This example will change the second Google link in the content, but not the first one or the one in the footer:
<div class="content">
<p>...link to <a href="http://www.google.com/">Google</a>
in the content...</p>
<p>...second link to <a href="http://www.google.com/"
id="changeme">Google</a>
in the content...</p>
</div>
<div class="footer">
Links: <a href="http://www.google.com/">Google</a>
</div>
$("a#changeme").attr('href',
'http://maps.google.com/');
Admitting you want to use some smtp server, you can do:
export SUBJECT=some_subject
export smtp=somehost:someport
export EMAIL=someaccount@somedomain
echo "some message" | mailx -s "$SUBJECT" "$EMAIL"
Change somehost
, someport
, and someaccount@somedomain
to actual values that you would use.
No encryption and no authentication is performed in this example.
List.indexOf()
will give you what you want, provided you know precisely what you're after, and provided that the equals()
method for Party
is well-defined.
Party searchCandidate = new Party("FirstParty");
int index = cave.parties.indexOf(searchCandidate);
This is where it gets interesting - subclasses shouldn't be examining the private properties of their parents, so we'll define equals()
in the superclass.
@Override
public boolean equals(Object o) {
if (this == o) {
return true;
}
if (!(o instanceof CaveElement)) {
return false;
}
CaveElement that = (CaveElement) o;
if (index != that.index) {
return false;
}
if (name != null ? !name.equals(that.name) : that.name != null) {
return false;
}
return true;
}
It's also wise to override hashCode
if you override equals
- the general contract for hashCode
mandates that, if x.equals(y)
, then x.hashCode() == y.hashCode().
@Override
public int hashCode() {
int result = name != null ? name.hashCode() : 0;
result = 31 * result + index;
return result;
}
You have to escape the & character. Turn your
&
into
&
and you should be good.
SELECT t1.a, t2.b
FROM t1

Like it has been said few times, you need to change your selector to
$("input[name='bla[]']")
But I want to add, you have to use single or double quotes when using [] in selector.

I found on the sqlite documentation (https://www.sqlite.org/lang_datefunc.html) this text:
Compute the date and time given a unix timestamp 1092941466, and compensate for your local timezone.
SELECT datetime(1092941466, 'unixepoch', 'localtime');
That didn't look like it fit my needs, so I tried changing the "datetime" function around a bit, and wound up with this:
select datetime(timestamp, 'localtime')
That seems to work - is that the correct way to convert for your timezone, or is there a better way to do this?
We had the Broken Pipe error after a new network was put into place. After ensuring that port 9100 was open and could connect to the printer over telnet port 9100, we changed the printer driver from "HP" to "Generic PDF", the broken pipe error went away and were able to print successfully.
(RHEL 7, Printers were Ricoh brand, the HP configuration was pre-existing and functional on the previous network)

Are you sure the problem isn't that your shell script is changing directory in its subshell, but then you're back in the main shell (and original dir) when done? I avoided that by using . to run the script in the current shell, though most folks would just use an alias for this. The spaces could be a red herring.
To save as data:
From StoryBoard, if you want to save "image" data on the imageView of MainStoryBoard, following codes will work.
let image = UIImagePNGRepresentation(imageView.image!) as NSData?
To load "image" to imageView: Look at exclamation point "!", "?" closely whether that is quite same as this one.
imageView.image = UIImage(data: image as! Data)
"NSData" type is converted into "Data" type automatically during this process.
you can combine asList and split
Arrays.asList(CommaSeparated.split("\\s*,\\s*"))

No. The first returns a DOM element, or null, whereas the second always returns a jQuery object. The jQuery object will be empty if no element with the id of contents
was matched.
The DOM element returned by document.getElementById('contents')
allows you to do things such as change the .innerHTML
(or .value
) etc, however you'll need to use jQuery methods on the jQuery Object.
var contents = $('#contents').get(0);
Is more equivilent, however if no element with the id of contents
is matched, document.getElementById('contents')
will return null, but $('#contents').get(0)
will return undefined.
One benefit on using the jQuery object is that you won't get any errors if no elements were returned, as an object is always returned. However you will get errors if you try to perform operations on the null
returned by document.getElementById
You just have to use class="row-eq-height"

Yes, it is possible to add metatags with Javascript. I did in my example
Android not respecting metatag removal?
But, I dont know how to change it other then removing it. Btw, in my example.. when you click the 'ADD' button it adds the tag and the viewport changes respectively but I dont know how to revert it back (remove it, in Android).. I wish there was firebug for Android so I saw what was happening. Firefox does remove the tag. if anybody has any ideas on this please note so in my question.
If you use InnoDB and defined FK's you could query the information_schema database e.g.:
SELECT * FROM information_schema.TABLE_CONSTRAINTS
WHERE information_schema.TABLE_CONSTRAINTS.CONSTRAINT_TYPE = 'FOREIGN KEY'
AND information_schema.TABLE_CONSTRAINTS.TABLE_SCHEMA = 'myschema'
AND information_schema.TABLE_CONSTRAINTS.TABLE_NAME = 'mytable';
Once you set up ssh-keygen
as explained above, you can do
scp -i ~/.ssh/id_rsa /local/path/to/file [email protected]:/path/in/remote/server/
If you want to lessen typing each time, you can modify your .bash_profile
file and put
alias remote_scp='scp -i ~/.ssh/id_rsa /local/path/to/file [email protected]:/path/in/remote/server/
Then from your terminal do source ~/.bash_profile
. Afterwards if you type remote_scp
in your terminal it should run the scp
command without password.
If you mean use the same code but add a new line so that when you add something to the file it will be on a new line. You can simply use BufferedWriter's newLine()
.
Here I have Improved you code also: NumberFormatException was unnecessary as nothing was being cast to a number data type, saving variables to use once also was.
try {
BufferedWriter writer = new BufferedWriter(new FileWriter("file.txt"));
writer.write(jTextField1.getText());
writer.write(jTextField2.getText());
writer.newLine();
writer.flush();
writer.close();
} catch (IOException ex) {
System.out.println("File could not be created");
}
Array and Object is passed as pass by reference or pass by value based on these two condition.
if you are changing value of that Object or array with new Object or Array then it is pass by Value.
object1 = {item: "car"};
array1=[1,2,3];
here you are assigning new object or array to old one.you are not changing the value of property of old object.so it is pass by value.
if you are changing a property value of an object or array then it is pass by Reference.
object1.item= "car";
array1[0]=9;
here you are changing a property value of old object.you are not assigning new object or array to old one.so it is pass by reference.
Code
function passVar(object1, object2, number1) {
object1.key1= "laptop";
object2 = {
key2: "computer"
};
number1 = number1 + 1;
}
var object1 = {
key1: "car"
};
var object2 = {
key2: "bike"
};
var number1 = 10;
passVar(object1, object2, number1);
console.log(object1.key1);
console.log(object2.key2);
console.log(number1);
Output: -
laptop
bike
10
I prefer using regex like this:
NSString *myString = @"this is a test";
NSString *myNewString = [myString stringByReplacingOccurrencesOfString:@"\\s"
withString:@""
options:NSRegularExpressionSearch
range:NSMakeRange(0, [myStringlength])];
//myNewString will be @"thisisatest"
You can make yourself a category on NSString to make life even easier:
- (NSString *) removeAllWhitespace
{
return [self stringByReplacingOccurrencesOfString:@"\\s" withString:@""
options:NSRegularExpressionSearch
range:NSMakeRange(0, [self length])];
}
Here is a unit test method on it too:
- (void) testRemoveAllWhitespace
{
NSString *testResult = nil;
NSArray *testStringsArray = @[@""
,@" "
,@" basicTest "
,@" another Test \n"
,@"a b c d e f g"
,@"\n\tA\t\t \t \nB \f C \t ,d,\ve F\r\r\r"
,@" landscape, portrait, ,,,up_side-down ;asdf; lkjfasdf0qi4jr0213 ua;;;;af!@@##$$ %^^ & * * ()+ + "
];
NSArray *expectedResultsArray = @[@""
,@""
,@"basicTest"
,@"anotherTest"
,@"abcdefg"
,@"ABC,d,eF"
,@"landscape,portrait,,,,up_side-down;asdf;lkjfasdf0qi4jr0213ua;;;;af!@@##$$%^^&**()++"
];
for (int i=0; i < [testStringsArray count]; i++)
{
testResult = [testStringsArray[i] removeAllWhitespace];
STAssertTrue([testResult isEqualToString:expectedResultsArray[i]], @"Expected: \"%@\" to become: \"%@\", but result was \"%@\"",
testStringsArray[i], expectedResultsArray[i], testResult);
}
}
Hows about this:
$json=Get-Content -Raw -Path 'my.json' | Out-String | ConvertFrom-Json
$foo="TheVariableYourUsingToSelectSomething"
$json.SomePathYouKnow.psobject.properties.Where({$_.name -eq $foo}).value
which would select from json structured
{"SomePathYouKnow":{"TheVariableYourUsingToSelectSomething": "Tada!"}

This is a perfect use-case for DISTINCT ON
- a Postgres specific extension of the standard DISTINCT
:
SELECT DISTINCT ON (category)
id -- , category, date -- any other column (expression) from the same row
FROM tbl
ORDER BY category, date DESC;
Careful with descending sort order. If the column can be NULL, you may want to add NULLS LAST
:
DISTINCT ON
is simple and fast. Detailed explanation in this related answer:
For big tables with many rows per category
consider an alternative approach:
You can change it directly in styles.xml file \app\src\main\res\values\styles.xml
This work on older versions, I was changing it in KitKat and come here.
You can use multiple way based on sitaution:
If you Variable is limited to specific Number or String, best way is using ngSwitch or ngIf:
<!-- foo = 3 -->
<div [ngSwitch]="foo">
<div *ngSwitchCase="1">First Number</div>
<div *ngSwitchCase="2">Second Number</div>
<div *ngSwitchCase="3">Third Number</div>
<div *ngSwitchDefault>Other Number</div>
</div>
<!-- foo = 3 -->
<ng-template [ngIf]="foo === 1">First Number</ng-template>
<ng-template [ngIf]="foo === 2">Second Number</ng-template>
<ng-template [ngIf]="foo === 3">Third Number</ng-template>
<!-- foo = 'David' -->
<div [ngSwitch]="foo">
<div *ngSwitchCase="'Daniel'">Daniel String</div>
<div *ngSwitchCase="'David'">David String</div>
<div *ngSwitchCase="'Alex'">Alex String</div>
<div *ngSwitchDefault>Other String</div>
</div>
<!-- foo = 'David' -->
<ng-template [ngIf]="foo === 'Alex'">Alex String</ng-template>
<ng-template [ngIf]="foo === 'David'">David String</ng-template>
<ng-template [ngIf]="foo === 'Daniel'">Daniel String</ng-template>
Above not suitable for if elseif else codes and dynamic codes, you can use below code:
<!-- foo = 5 -->
<ng-container *ngIf="foo >= 1 && foo <= 3; then t13"></ng-container>
<ng-container *ngIf="foo >= 4 && foo <= 6; then t46"></ng-container>
<ng-container *ngIf="foo >= 7; then t7"></ng-container>
<!-- If Statement -->
<ng-template #t13>
Template for foo between 1 and 3
</ng-template>
<!-- If Else Statement -->
<ng-template #t46>
Template for foo between 4 and 6
</ng-template>
<!-- Else Statement -->
<ng-template #t7>
Template for foo greater than 7
</ng-template>
Note: You can choose any format, but notice every code has own problems
If you follow conventional ports since HTTP tries port 80 by default and HTTPS tries port 443 by default you can simply have two server's on the same machine: Here's the code:
var https = require('https');
var fs = require('fs');
var options = {
key: fs.readFileSync('./key.pem'),
cert: fs.readFileSync('./cert.pem')
};
https.createServer(options, function (req, res) {
res.end('secure!');
}).listen(443);
// Redirect from http port 80 to https
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(301, { "Location": "https://" + req.headers['host'] + req.url });
res.end();
}).listen(80);
Test with https:
$ curl https://127.0.0.1 -k
secure!
With http:
$ curl http://127.0.0.1 -i

Your repo is yours, what goes on in it is entirely your business until you push or (allow a) fetch or clone. When you deleted your windows repo -- that folder didn't represent your local repo, it was your actual local repo, you deleted everything done in it that was never pushed, fetched or cloned.
edit: Ah, okay, I think I see what's going on here: you pushed to your linux repo but it's not bare and you never worked in it.
Instead of git log
, do git log --all
. Or git checkout
some-branch-name
.
Then try cloning the repo locally, on your linux box; I bet it works. What are you using to serve your repo on linux? Try cd'ing into its .git directory and git daemon --base-path=. --export-all
, if that just sits there then go to your windows box and try git clone git://your.linux.box.ip
, if the daemon complains it can't bind add --port=54345
to the daemon invoke and :54345
to the clone url.

You can use
catch(...)
but that is very dangerous. In his book Debugging Windows, John Robbins tells a war story about a really nasty bug that was masked by a catch(...) command. You're much better off catching specific exceptions. Catch whatever you think your try block might reasonably throw, but let the code throw an exception higher up if something really unexpected happens.
Calculate x/y
(your actual numbers here), and press a b/c key, which is 3rd one below Shift key.
To stick to ==
without consideration of the other type, the following is also possible.
type(a) == type(None)
By default, plot does show axes, unless you've modified some settings. Try the following
hold on; % make sure no new plot window is created on every plot command
axes(); % produce plot window with axes
plot(% whatever your plot command is);
plot([0 10], [0 0], 'k-'); % plot the horizontal line
On the Macintosh, place the cursor after either the opening or closing curly brace }

ALTER TABLE SCHEMA.TABLENAME
MODIFY (COLUMNNAME NEWDATATYPE(LENGTH)) ;
For example,
ALTER TABLE PAYROLL.EMPLOYEES
MODIFY (JOBTITLE VARCHAR2(12)) ;
Try this:
Select Project_Name, ReleaseDate, TaskName
From DB_Table
Where Project_Name like '{?Pm-?Proj_Name}'
And ReleaseDate >= currentdate
currentdate should be a valid database function or field to work. If you are using MS SQL Server, use GETDATE() instead.
If all you want is to filter records in a subreport based on a parameter from the main report, it might be easier to simply add the table to the subreport, and then create a Project_Name link between the main report and subreport. You can then use the Select Expert to filter the ReleaseDate as well.
\df <schema>.*
in psql
gives the necessary information.
To see the query that's used internally connect to a database with psql
and supply an extra "-E
" (or "--echo-hidden
") option and then execute the above command.
Use /config.php
.
Force a method to get the struct (the constructor way).
From this post:
A good design is to make your type unexported, but provide an exported constructor function like
NewMyType()
in which you can properly initialize your struct / type. Also return an interface type and not a concrete type, and the interface should contain everything others want to do with your value. And your concrete type must implement that interface of course.
This can be done by simply making the type itself unexported. You can export the function NewSomething and even the fields Text and DefaultText, but just don't export the struct type something.
Another way to customize it for you own module is by using a Config struct to set default values (Option 5 in the link). Not a good way though.

SymmetricDS is the answer. It supports multiple subscribers with one direction or bi-directional asynchronous data replication. It uses web and database technologies to replicate tables between relational databases, in near real time if desired.
Comprehensive and robust Java API to suit your needs.
If you just want to drop the database no matter what (but please first read the whole post: the error was given for a reason, and it might be important to know what the reason was!), you can:
SHOW VARIABLES WHERE Variable_name LIKE '%datadir%';
service mysql stop
or rcmysqld stop
or similar on Linux, NET STOP <name of MYSQL service, often MYSQL57 or similar>
or through SERVICES.MSC
on Windows)MySQL has no write permission on the parent directory in which the mydb
folder resides.
Check it with
ls -la /path/to/data/dir/ # see below on how to discover data dir
ls -la /path/to/data/dir/mydb
On Linux, this can also happen if you mix and match MySQL and AppArmor/SELinux packages. What happens is that AppArmor expects mysqld to have its data in /path/to/data/dir
, and allows full R/W there, but MySQLd is from a different distribution or build, and it actually stores its data elsewhere (e.g.: /var/lib/mysql5/data/**
as opposed to /var/lib/mysql/**
). So what you see is that the directory has correct permissions and ownership and yet it still gives Errno 13 because apparmor/selinux won't allow access to it.
To verify, check the system log for security violations, manually inspect apparmor/selinux configuration, and/or impersonate the mysql user and try going to the base var directory, then cd incrementally until you're in the target directory, and run something like touch aardvark && rm aardvark
. If permissions and ownership match, and yet the above yields an access error, chances are that it's a security framework issue.
"EASY FIX" considered harmful
I have happened upon an "easy fix" suggested on a "experts forum" (not Stack Overflow, thank goodness), the same "fix" I sometimes find for Web and FTP problems --
chown 777
. PLEASE NEVER DO THAT. For those who don't already know, 777 (or 775, or 666) isn't a magic number that somehow MySQL programmers forgot to apply themselves, or don't want you to know. Each digit has a meaning, and 777 means "I hereby consent to everyone doing whatever they want with my stuff, up to and including executing it as if it were a binary or shell script". By doing this (and chances are you won't be allowed to do this on a sanely configured system),
- you risk several security conscious programs to refuse to function anymore (e.g. if you do that to your SSH keys, goodbye SSH connections; etc.) since they realize they're now in a insecure context.
- you allow literally everyone with any level of access whatsoever to the system to read and write your data, whether MySQL allows it or not, unbeknownst to MySQL itself - i.e. it becomes possible to silently corrupt whole databases.
- the above might sometimes be done, in exceedingly dire straits, by desperate and knowledgeable people, to gain access again to an otherwise inaccessible screwed MySQL installation (i.e. even
mysqladmin
no longer grants local access), and will be immediately undone as soon as things get back to normal - it's not a permanent change, not even then. And it's not a fix to "one weird trick to be able to drop my DB".(needless to say, it's almost never the real fix to any Web or FTP problems either. The fix to "Of late, the wife's keys fail to open the front door and she can't enter our home" is 'check the keys or have the lock repaired or replaced'; the admittedly much quicker
chown 777
is "Just leave the front door wide open! Easy peasy! What's the worst that might happen?")
This code means "directory not empty". The directory contains some hidden files MySQL knows nothing about. For non-hidden files, see Errno 17. The solution is the same.
This code means "file exists". The directory contains some MySQL file that MySQL doesn't feel about deleting. Such files could have been created by a SELECT ... INTO OUTFILE "filename";
command where filename
had no path. In this case, the MySQL process creates them in its current working directory, which (tested on MySQL 5.6 on OpenSuSE 12.3) is the data directory of the database, e.g. /var/lib/mysql/data/nameofdatabase
.

Move the file(s) outside (or delete if not needed) and retry. Also, determine why they were created in the first place - it could point to a bug in some application. Or worse: see below...
This happened on a Linux system with Wordpress installed. Unfortunately the customer was under time constraints and I could neither image the disk or do a real forensics round - I reinstalled the whole machine and Wordpress got updated in the process, so I can only say that I'm almost certain they did it through this plugin.
Symptoms: the mysql
data directory contained three files with extension PHP. Wait, what?!? -- and inside the files there was a bulk of base64 code which was passed to base64_decode
, gzuncompress
and [eval()][2]
. Aha. Of course these were only the first attempts, the unsuccessful ones. The site had been well and truly pwn3d.
So if you find a file in your mysql data dir that's causing an Error 17, check it with file
utility or scan it with an antivirus. Or visually inspect its contents. Do not assume it's there for some innocuous mistake.
(Needless to say, to visually inspect the file, never double click it).
The victim in this case (he had some friend "do the maintenance") would never have guessed he'd been hacked until a maintenance/update/whatever script ran a DROP DATABASE
(do not ask me why - I'm not sure even I want to know) and got an error. From the CPU load and the syslog messages, I'm fairly positive that the host had become a spam farm.
If you rsync
or copy between two MySQL installations of the same version but different platform or file systems such as Linux or Windows (which is discouraged, and risky, but many do it nonetheless), and specifically with different case sensitivity settings, you can accidentally end up with two versions of the same file (either data, index, or metadata); say Customers.myi
and Customer.MYI
. MySQL uses one of them and knows nothing about the other (which could be out of date and lead to a disastrous sync). When dropping the database, which also happens in many a mysqldump ... | ... mysql
backup schemes, the DROP
will fail because that extra file (or those extra files) exists. If this happens, you should be able to recognize the obsolete file(s) that need manual deletion from the file time, or from the fact that their case scheme is different from the majority of the other tables.
In general, you can find the data directory by inspecting the my.cnf
file (/etc/my.cnf
, /etc/sysconfig/my.cnf
, /etc/mysql/my.cnf
on Linux; my.ini
in the MySQL program files directory in Windows), under the [mysqld]
heading, as datadir
.
Alternatively you can ask it to MySQL itself:
mysql> SHOW VARIABLES WHERE Variable_name LIKE '%datadir%';
+---------------+-----------------+
| Variable_name | Value |
+---------------+-----------------+
| datadir | /var/lib/mysql/ |
+---------------+-----------------+

}, { duration: 200, queue: false });
$("#second").animate({

}, { duration: 200, queue: false });
});
Use r.URL.Query()
when you appending to existing query, if you are building new set of params use the url.Values
struct like so
package main
import (
"fmt"
"log"
"net/http"
"net/url"
"os"
)
func main() {
req, err := http.NewRequest("GET","http://api.themoviedb.org/3/tv/popular", nil)
if err != nil {
log.Print(err)
os.Exit(1)
}
// if you appending to existing query this works fine
q := req.URL.Query()
q.Add("api_key", "key_from_environment_or_flag")
q.Add("another_thing", "foo & bar")
// or you can create new url.Values struct and encode that like so
q := url.Values{}
q.Add("api_key", "key_from_environment_or_flag")
q.Add("another_thing", "foo & bar")
req.URL.RawQuery = q.Encode()
fmt.Println(req.URL.String())
// Output:
// http://api.themoviedb.org/3/tv/popularanother_thing=foo+%26+bar&api_key=key_from_environment_or_flag
}
dtList = dtList.Where(s => !string.IsNullOrWhiteSpace(s)).Distinct().ToList()
I assumed empty string and whitespace are like null. If not you can use IsNullOrEmpty
(allow whitespace), or s != null
See wtk's answer.
A more straightforward way to do this would be to use resolve.root.
http://webpack.github.io/docs/configuration.html#resolve-root
resolve.root
The directory (absolute path) that contains your modules. May also be an array of directories. This setting should be used to add individual directories to the search path.
In your case:
var path = require('path');
// ...
resolve: {
root: path.resolve('./mydir'),
extensions: ['', '.js']
}
require('myfile')
or
require('myfile.js')
see also: http://webpack.github.io/docs/configuration.html#resolve-modulesdirectories
top, parent, opener (as well as window, self, and iframe) are all window objects.
window.opener
-> returns the window that opens or launches the current popup window.window.top
-> returns the topmost window, if you're using frames, this is the frameset window, if not using frames, this is the same as window or self.window.parent
-> returns the parent frame of the current frame or iframe. The parent frame may be the frameset window or another frame if you have nested frames. If not using frames, parent is the same as the current window or selfThis is a new feature of C# 6 called an expression bodied member that allows you to define a getter only property using a lambda like function.
While it is considered syntactic sugar for the following, they may not produce identical IL:
public int MaxHealth
{
get
{
return Memory[Address].IsValid
? Memory[Address].Read<int>(Offs.Life.MaxHp)

Note that expression-bodied members were expanded to include properties, constructors, finalizers and indexers in C# 7.0.
Just set view engine in your code.
var app = express();
app.set('view engine', 'ejs');
To get the current directory, you can use this:
CD > tmpFile
SET /p myvar= < tmpFile
DEL tmpFile
echo test: %myvar%
It's using a temp-file though, so it's not the most pretty, but it certainly works! 'CD' puts the current directory in 'tmpFile', 'SET' loads the content of tmpFile.
Here is a solution for multiple lines with "array's":
@echo off
rem ---------
rem Obtain line numbers from the file
rem ---------
rem This is the file that is being read: You can replace this with %1 for dynamic behaviour or replace it with some command like the first example i gave with the 'CD' command.
set _readfile=test.txt
for /f "usebackq tokens=2 delims=:" %%a in (`find /c /v "" %_readfile%`) do set _max=%%a
set /a _max+=1
set _i=0
set _filename=temp.dat
rem ---------
rem Make the list
rem ---------
:makeList
find /n /v "" %_readfile% >%_filename%
rem ---------
rem Read the list
rem ---------
:readList
if %_i%==%_max% goto printList
rem ---------
rem Read the lines into the array
rem ---------
for /f "usebackq delims=] tokens=2" %%a in (`findstr /r "\[%_i%]" %_filename%`) do set _data%_i%=%%a
set /a _i+=1
goto readList
:printList
del %_filename%
set _i=1
:printMore
if %_i%==%_max% goto finished
set _data%_i%
set /a _i+=1
goto printMore
:finished
But you might want to consider moving to another more powerful shell or create an application for this stuff. It's stretching the possibilities of the batch files quite a bit.
Is there any reason you have to hook and test for the enter key?
Couldn't you simply add a
<input type="submit" />
to your form and have it naturally be submitted when enter is pushed? You could even then hook the form's onsubmit
action and call a validation function from there if you wanted...
You could even use the onsubmit
as a test to see if your form is being submitted, but it won't work if you call form.submit()
.
javascript:document.getElementsByClassName("video-stream html5-main-video")[0].playbackRate = 0.1;
you can put any number here just don't go to far so you don't overun your computer.
I was just playing around with doing this too, and this seemed to be the best option for me:
<style>
tr {
display: table; /* this makes borders/margins work */
border: 1px solid black;
margin: 5px;
}
</style>
Note that this will prevent the use of fluid/automatic column widths, as cells will no longer align with those in other rows, but border/colour formatting still works OK. The solution is to give the TR and TDs a specified width (either px or %).
Of course you could make the selector tr.myClass
if you wanted to apply it only to certain rows. Apparently display: table
doesn't work for IE 6/7, however, but there's probably other hacks (hasLayout?) that might work for those. :-(
You can use casting in the select clause like:
SELECT id, name, CAST(hide AS BOOLEAN) FROM table_name;
I disagree with the popular answer, that having public implies that there are other options and so it shouldn't be there. The fact is that now with Java 9 and beyond there ARE other options.
I think instead Java should enforce/require 'public' to be specified. Why? Because the absence of a modifier means 'package' access everywhere else, and having this as a special case is what leads to the confusion. If you simply made it a compile error with a clear message (e.g. "Package access is not allowed in an interface.") we would get rid of the apparent ambiguity that having the option to leave out 'public' introduces.
Note the current wording at: https://docs.oracle.com/javase/specs/jls/se9/html/jls-9.html#jls-9.4
"A method in the body of an interface may be declared public or private (§6.6). If no access modifier is given, the method is implicitly public. It is permitted, but discouraged as a matter of style, to redundantly specify the public modifier for a method declaration in an interface."
See that 'private' IS allowed now. I think that last sentence should have been removed from the JLS. It is unfortunate that the "implicitly public" behaviour was ever allowed as it will now likely remain for backward compatibilty and lead to the confusion that the absence of the access modifier means 'public' in interfaces and 'package' elsewhere.
Or you can use this javascript
$(function () {
$("#projectKey").change(function () {
alert($('#projectKey option:selected').text());
});
});
An Identifying relationship specifies that a child object cannot exist without the parent object
Non-identifying relationships specifies a regular association between objects, 1:1 or 1:n cardinality.
Non-identifying relationships can be specified as optional where a parent is not required or mandatory where a parent is required by setting the parent table cardinality...
My inclination was to add this as an extension to NSAttributedString
rather than String
. I tried it as a static extension and an initializer. I prefer the initializer which is what I've included below.
Swift 4
internal convenience init?(html: String) {
guard let data = html.data(using: String.Encoding.utf16, allowLossyConversion: false) else {
return nil
}
guard let attributedString = try? NSAttributedString(data: data, options: [.documentType: NSAttributedString.DocumentType.html, .characterEncoding: String.Encoding.utf8.rawValue], documentAttributes: nil) else {
return nil
}
self.init(attributedString: attributedString)
}
Swift 3
extension NSAttributedString {
internal convenience init?(html: String) {
guard let data = html.data(using: String.Encoding.utf16, allowLossyConversion: false) else {
return nil
}
guard let attributedString = try? NSMutableAttributedString(data: data, options: [NSAttributedString.DocumentReadingOptionKey.documentType: NSAttributedString.DocumentType.html], documentAttributes: nil) else {
return nil
}
self.init(attributedString: attributedString)
}
}
Example
let html = "<b>Hello World!</b>"
let attributedString = NSAttributedString(html: html)
I encountered this issue when installing a different package, and it could be caused by the GOROOT and GOPATH configuration on your PATH. I tend not to set GOROOT because my OS X installation handled it (I believe) for me.
Ensure the following in your .profile (or wherever you store profile configuration: .bash_profile, .zshrc, .bashrc, etc):
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin
Also, you likely want to unset GOROOT
, as well, in case that path is also incorrect.
Furthermore, be sure to clean your PATH, similarly to what I've done below, just before the GOPATH assignment, i.e.:
export PATH=$HOME/bin:/usr/local/bin:$PATH
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin
Then, source <.profile>
to activate
go get
Okay I fixed this thing. Had to first convert the projects to Maven Projects, then remove them from the Eclipse workspace, and then re-import them.
If the query's column has an appropriate type then
var dateString = MyReader.GetDateTime(MyReader.GetOrdinal("column")).ToString(myDateFormat)
If the query's column is actually a string then see other answers.
As most of us use Eclipse already for writing code, Why not use the Memory Analyser Tool(MAT) in Eclipse. It works great.
The Eclipse MAT is a set of plug-ins for the Eclipse IDE which provides tools to analyze heap dumps
from Java application and to identify memory problems
in the application.
This helps the developer to find memory leaks with the following features
Try this. For me it worked
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayUseLogoEnabled(true);
In simple terms you need to build your payload into a key array
payload = {'key1': 'value1', 'key2': 'value2'}
Then send the payload directly to the action
this.$store.dispatch('yourAction', payload)
No change in your action
yourAction: ({commit}, payload) => {
commit('YOUR_MUTATION', payload )
},
In your mutation call the values with the key
'YOUR_MUTATION' (state, payload ){
state.state1 = payload.key1
state.state2 = payload.key2
},
I don't know about CLI, I had tried, but I couldn't. I deleted using IDE Idea history.
If You use an Intellij Idea, just open History changes.
Tap by main folder of the project -> right click -> local history -> show history.
Then from top to bottom revert changes.
It should help! Good luck!=)
You may use this..
<body>
<form method="" action="">
<input type="text" name="email" class="input" />
<input type="submit" value="Sign Up" class="button" />
</form>
</body>
<script>
$(document).ready(function() {
$(".input").val("Email Address");
$(".input").on("focus", function() {
$(".input").val("");
});
$(".button").on("click", function(event) {
$(".input").val("");
});
});
</script>
Talking of your own code, the problem is that the attr api of jquery is set by
$('.input').attr('value','Email Adress');
and not as you have done:
$('.input').attr('value') = 'Email address';
This is because Properties
extends Hashtable<Object, Object>
(which, in turn, implements Map<Object, Object>
). You attempt to feed that into a Map<String, String>
. It is therefore incompatible.
You need to feed string properties one by one into your map...
For instance:
for (final String name: properties.stringPropertyNames())
map.put(name, properties.getProperty(name));
I had the same problem, and just found a handling not mentioned here. Though I'd contribute to the community:
npm install -g myapp
was not copying the bin
directory. I found this to be because I did not include it in the files
in my package.json
"files": [
"lib",
"bin" // this was missing
]
You can use Javascript.
For example, using jQuery:
$(':text').val('1000');
However, this won't be any different from using the value
attribute.
Here is an example of how you can do it in "classic" R graphics:
## generate some random data
carrotLengths <- rnorm(1000,15,5)
cucumberLengths <- rnorm(200,20,7)
## calculate the histograms - don't plot yet
histCarrot <- hist(carrotLengths,plot = FALSE)
histCucumber <- hist(cucumberLengths,plot = FALSE)
## calculate the range of the graph
xlim <- range(histCucumber$breaks,histCarrot$breaks)
ylim <- range(0,histCucumber$density,
histCarrot$density)
## plot the first graph
plot(histCarrot,xlim = xlim, ylim = ylim,
col = rgb(1,0,0,0.4),xlab = 'Lengths',
freq = FALSE, ## relative, not absolute frequency
main = 'Distribution of carrots and cucumbers')
## plot the second graph on top of this
opar <- par(new = FALSE)
plot(histCucumber,xlim = xlim, ylim = ylim,
xaxt = 'n', yaxt = 'n', ## don't add axes
col = rgb(0,0,1,0.4), add = TRUE,
freq = FALSE) ## relative, not absolute frequency
## add a legend in the corner
legend('topleft',c('Carrots','Cucumbers'),
fill = rgb(1:0,0,0:1,0.4), bty = 'n',
border = NA)
par(opar)
The only issue with this is that it looks much better if the histogram breaks are aligned, which may have to be done manually (in the arguments passed to hist
).
One the elements are added, use the rules method to add the rules
//bug fixed thanks to @Sparky
$('input[name^="fileupload"]').each(function () {
$(this).rules('add', {
required: true,
accept: "image/jpeg, image/pjpeg"
})
})
Demo: Fiddle
Update
var filenumber = 1;
$("#AddFile").click(function () { //User clicks button #AddFile
var $li = $('<li><input type="file" name="FileUpload' + filenumber + '" id="FileUpload' + filenumber + '" required=""/> <a href="#" class="RemoveFileUpload">Remove</a></li>').prependTo("#FileUploader");
$('#FileUpload' + filenumber).rules('add', {
required: true,
accept: "image/jpeg, image/pjpeg"
})
filenumber++;
return false;
});
try this. If you do like this you don't need to fire always any command You need to fire only one time
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
cat /proc/sys/fs/inotify/max_user_watches
fs.inotify.max_user_watches=524288
Assuming the type is CV_8UC3 you would do this:
for(int i = 0; i < foo.rows; i++)
{
for(int j = 0; j < foo.cols; j++)
{
Vec3b bgrPixel = foo.at<Vec3b>(i, j);
// do something with BGR values...
}
}
Here is the documentation for Vec3b. Hope that helps! Also, don't forget OpenCV stores things internally as BGR not RGB.
EDIT :
For performance reasons, you may want to use direct access to the data buffer in order to process the pixel values:
Here is how you might go about this:
uint8_t* pixelPtr = (uint8_t*)foo.data;
int cn = foo.channels();
Scalar_<uint8_t> bgrPixel;
for(int i = 0; i < foo.rows; i++)
{
for(int j = 0; j < foo.cols; j++)
{
bgrPixel.val[0] = pixelPtr[i*foo.cols*cn + j*cn + 0]; // B
bgrPixel.val[1] = pixelPtr[i*foo.cols*cn + j*cn + 1]; // G
bgrPixel.val[2] = pixelPtr[i*foo.cols*cn + j*cn + 2]; // R
// do something with BGR values...
}
}
Or alternatively:
int cn = foo.channels();
Scalar_<uint8_t> bgrPixel;
for(int i = 0; i < foo.rows; i++)
{
uint8_t* rowPtr = foo.row(i);
for(int j = 0; j < foo.cols; j++)
{
bgrPixel.val[0] = rowPtr[j*cn + 0]; // B
bgrPixel.val[1] = rowPtr[j*cn + 1]; // G
bgrPixel.val[2] = rowPtr[j*cn + 2]; // R
// do something with BGR values...
}
}
The error means that you have data in other tables that references the data you are trying to delete.
You would need to either drop and recreate the constraints or delete the data that the Foreign Key references.
Suppose you have the following tables
dbo.Students
(
StudentId
StudentName
StudentTypeId
)
dbo.StudentTypes
(
StudentTypeId
StudentType
)
Suppose a Foreign Key constraint exists between the StudentTypeId
column in StudentTypes
and the StudentTypeId
column in Students
If you try to delete all the data in StudentTypes
an error will occur as the StudentTypeId
column in Students
reference the data in the StudentTypes
table.
EDIT:
DELETE
and TRUNCATE
essentially do the same thing. The only difference is that TRUNCATE
does not save the changes in to the Log file. Also you can't use a WHERE
clause with TRUNCATE
AS to why you can run this in SSMS but not via your Application. I really can't see this happening. The FK constraint would still throw an error regardless of where the transaction originated from.
The plus sign is the historic encoding for a space character in URL parameters, as documented in the help for the urlencode()

That same page contains the answer you need - use rawurlencode()

I had the same problem ! but to solve it just modify your code as following.

Try going with Switch case or ternary operator
render(){
return (
<div>
<Element1/>
<Element2/>
// updated code works here
{(() => {
switch (this.props.hasImage) {
case (this.props.hasImage):
return <MyImage />;
default:
return (
<OtherElement/>;
);
}
})()}
</div>
)
}
This worked for me and should work for you else. Try Ternary Operator
try setting the display to block in your javascript instead of a blank value.

https://getbootstrap.com/docs/3.3/javascript/#dismiss-on-next-click
They recommend to use anchor tag not button and take care of role="button" + data-trigger="focus" + tabindex="0" attributes.
Ex:

data-trigger="focus" title="Dismissible popover" data-content="amazing content">

navigate to SmartGit preferences folder using terminal
cd /Library/Preferences/SmartGit/
use ls
command to see list of folders .. simply delete SmartGit version folder you find using command rm -r <main-smartgit-version>
and reopen the SmartGit app. :)
This seems to be a recent regression or some strange behavior in typescript. If you have the code:
const result = []
Usually it would be treated as if you wrote:
const result:any[] = []
however, if you have both noImplicitAny
FALSE, AND strictNullChecks
TRUE in your tsconfig, it is treated as:
const result:never[] = []
This behavior defies all logic, IMHO. Turning on null checks changes the entry types of an array?? And then turning on noImplicitAny
actually restores the use of any
without any warnings??
When you truly have an array of any
, you shouldn't need to indicate it with extra code.
I'm not 100% sure that I understand your question, so tell me if I'm wrong.
If I got it right, you are reading jbytes that are technically signed chars, but really pixel values ranging from 0 to 255, and you're wondering how you should handle them without corrupting the values in the process.
Then, you should do the following:
convert jbytes to unsigned char before doing anything else, this will definetly restore the pixel values you are trying to manipulate
use a larger signed integer type, such as int while doing intermediate calculations, this to make sure that over- and underflows can be detected and dealt with (in particular, not casting to a signed type could force to compiler to promote every type to an unsigned type in which case you wouldn't be able to detect underflows later on)
when assigning back to a jbyte, you'll want to clamp your value to the 0-255 range, convert to unsigned char and then convert again to signed char: I'm not certain the first conversion is strictly necessary, but you just can't be wrong if you do both
For example:
inline int fromJByte(jbyte pixel) {
// cast to unsigned char re-interprets values as 0-255
// cast to int will make intermediate calculations safer
return static_cast<int>(static_cast<unsigned char>(pixel));
}
inline jbyte fromInt(int pixel) {
if(pixel < 0)
pixel = 0;
if(pixel > 255)
pixel = 255;
return static_cast<jbyte>(static_cast<unsigned char>(pixel));
}
jbyte in = ...
int intermediate = fromJByte(in) + 30;
jbyte out = fromInt(intermediate);
Slightly related, I was looking for the unique combinations and I came up with this method:
def unique_columns(df,columns):
result = pd.Series(index = df.index)
groups = meta_data_csv.groupby(by = columns)
for name,group in groups:
is_unique = len(group) == 1
result.loc[group.index] = is_unique
assert not result.isnull().any()
return result
And if you only want to assert that all combinations are unique:
df1.set_index(['A','B']).index.is_unique
Instead of creating your own function, it would be useful to just negate the behavior of
needle %in% haystack
do this instead:
!(needle %in% haystack)
this works as well.
this modified code should work
p = ggplot(mydataf, aes(x = foo)) +
geom_bar(aes(y = (..count..)/sum(..count..))) +
scale_y_continuous(formatter = 'percent')
if your data has NAs and you dont want them to be included in the plot, pass na.omit(mydataf) as the argument to ggplot.
hope this helps.
As biziclop mentioned, some sort of metric space tree would probably be your best option. I have experience using kd-trees and quad trees to do these sorts of range queries and they're amazingly fast; they're also not that hard to write. I'd suggest looking into one of these structures, as they also let you answer other interesting questions like "what's the closest point in my data set to this other point?"
Set to cookie in the main domain -
document.cookie = "key=value;domain=.mydomain.com"
and then take the data from any main domain or sub domain and set it on the localStorage
That's constructor initialisation. It is the correct way to initialise members in a class constructor, as it prevents the default constructor being invoked.
Consider these two examples:
// Example 1
Foo(Bar b)
{
bar = b;
}
// Example 2
Foo(Bar b)
: bar(b)
{
}
In example 1:
Bar bar; // default constructor
bar = b; // assignment
In example 2:
Bar bar(b) // copy constructor
It's all about efficiency.

You need to say the following (since you befriend a whole template instead of just a specialization of it, in which case you would just need to add a <>
after the operator<<
):
template<typename T>
friend std::ostream& operator<<(std::ostream& out, const MyClass<T>& classObj);
Actually, there is no need to declare it as a friend unless it accesses private or protected members. Since you just get a warning, it appears your declaration of friendship is not a good idea. If you just want to declare a single specialization of it as a friend, you can do that like shown below, with a forward declaration of the template before your class, so that operator<<
is regognized as a template.
// before class definition ...
template <class T>
class MyClass;
// note that this "T" is unrelated to the T of MyClass !
template<typename T>
std::ostream& operator<<(std::ostream& out, const MyClass<T>& classObj);
// in class definition ...
friend std::ostream& operator<< <>(std::ostream& out, const MyClass<T>& classObj);
Both the above and this way declare specializations of it as friends, but the first declares all specializations as friends, while the second only declares the specialization of operator<<
as a friend whose T
is equal to the T
of the class granting friendship.
And in the other case, your declaration looks OK, but note that you cannot +=
a MyClass<T>
to a MyClass<U>
when T
and U
are different type with that declaration (unless you have an implicit conversion between those types). You can make your +=
a member template
// In MyClass.h
template<typename U>
MyClass<T>& operator+=(const MyClass<U>& classObj);
// In MyClass.cpp
template <class T> template<typename U>
MyClass<T>& MyClass<T>::operator+=(const MyClass<U>& classObj) {
// ...
return *this;

arr = [1,9,5,2,4,9,5,8,7,9,0,8,2,7,5,8,0,2,9]
arr[rand(arr.count)]
This will return a random element from array.
If You will use the line mentioned below
arr[1+rand(arr.count)]
then in some cases it will return 0 or nil value.
The line mentioned below
rand(number)
always return the value from 0 to number-1.
If we use
1+rand(number)
then it may return number and arr[number] contains no element.

relative to a parent element instead of the viewport (kinda*). It is achieved by setting the parent div
to position: relative;
and having a button wrapper with position: absolute;
and the button of course is position: fixed;
as follows:
<div class="wrapper">
<div class="content">
Your long content here
</div>
<div class="button-wrapper">
<button class="button">This is your button</button>
</div>
</div>
<style>
.wrapper {
position: relative;
}
.button-wrapper {
position: absolute;
right: 0;
top: 0;
width: 50px;
}
.button {
position: fixed;
top: 0;
width: 50px;
}
</style>
*Since fixed elements don't scroll with the page the vertical position will still be relative to the viewport but the horizontal position is relative to the parent with this solution.
return false;
at the end of the onclick handler will do the job. However, it's be better to simply add type="button"
to the <button>
- that way it behaves properly even without any JavaScript.
The typical pattern is to check out the root project folder (=the one containing a file called ".project") from SVN using eclipse's svn integration (SVN repository exploring perspective). The project is then recognized automatically.
From msdn:
The order of the returned file names is not guaranteed; use the Sort() method if a specific sort order is required.
The Sort() method is the standard Array.Sort(), which takes in IComparables (among other overloads), so if you sort by creation date, it will handle localization based on the machine settings.
Just in case you are like me and the Id Field of the User Entity is an Int or something else other than a string,
using Microsoft.AspNet.Identity;
int userId = User.Identity.GetUserId<int>();
will do the trick
You can use this :
$this->db->select('*');
$this->db->from('mytable');
$this->db->where(name,'Joe');
$bind = array('boss', 'active');
$this->db->where_in('status', $bind);
Yeah it is possible with FileReader, I have already done an example of this, here's the code:
<!DOCTYPE html>
<html>
<head>
<title>Read File (via User Input selection)</title>
<script type="text/javascript">
var reader; //GLOBAL File Reader object for demo purpose only
/**
* Check for the various File API support.
*/
function checkFileAPI() {
if (window.File && window.FileReader && window.FileList && window.Blob) {
reader = new FileReader();
return true;
} else {
alert('The File APIs are not fully supported by your browser. Fallback required.');
return false;
}
}
/**
* read text input
*/
function readText(filePath) {
var output = ""; //placeholder for text output
if(filePath.files && filePath.files[0]) {
reader.onload = function (e) {
output = e.target.result;
displayContents(output);
};//end onload()
reader.readAsText(filePath.files[0]);
}//end if html5 filelist support
else if(ActiveXObject && filePath) { //fallback to IE 6-8 support via ActiveX
try {
reader = new ActiveXObject("Scripting.FileSystemObject");
var file = reader.OpenTextFile(filePath, 1); //ActiveX File Object
output = file.ReadAll(); //text contents of file
file.Close(); //close file "input stream"
displayContents(output);
} catch (e) {
if (e.number == -2146827859) {
alert('Unable to access local files due to browser security settings. ' +
'To overcome this, go to Tools->Internet Options->Security->Custom Level. ' +
'Find the setting for "Initialize and script ActiveX controls not marked as safe" and change it to "Enable" or "Prompt"');
}
}
}
else { //this is where you could fallback to Java Applet, Flash or similar
return false;
}
return true;
}
/**
* display content using a basic HTML replacement
*/
function displayContents(txt) {
var el = document.getElementById('main');
el.innerHTML = txt; //display output in DOM
}
</script>
</head>
<body onload="checkFileAPI();">
<div id="container">
<input type="file" onchange='readText(this)' />
<br/>
<hr/>
<h3>Contents of the Text file:</h3>
<div id="main">
...
</div>
</div>
</body>
</html>
It's also possible to do the same thing to support some older versions of IE (I think 6-8) using the ActiveX Object, I had some old code which does that too but its been a while so I'll have to dig it up I've found a solution similar to the one I used courtesy of Jacky Cui's blog and edited this answer (also cleaned up code a bit). Hope it helps.
Lastly, I just read some other answers that beat me to the draw, but as they suggest, you might be looking for code that lets you load a text file from the server (or device) where the JavaScript file is sitting. If that's the case then you want AJAX code to load the document dynamically which would be something as follows:
<!DOCTYPE html>
<html>
<head><meta charset="utf-8" />
<title>Read File (via AJAX)</title>
<script type="text/javascript">
var reader = new XMLHttpRequest() || new ActiveXObject('MSXML2.XMLHTTP');
function loadFile() {
reader.open('get', 'test.txt', true);
reader.onreadystatechange = displayContents;
reader.send(null);
}
function displayContents() {
if(reader.readyState==4) {
var el = document.getElementById('main');
el.innerHTML = reader.responseText;
}
}
</script>
</head>
<body>
<div id="container">
<input type="button" value="test.txt" onclick="loadFile()" />
<div id="main">
</div>
</div>
</body>
</html>
You have "int* arr" so "arr[n]" is an int, right? Then your "[M - 1 + 1]" bit is trying to use that int as an array/pointer/vector.
HTML Component
<input type="text" [formControl]="txtValue">
TS Component
public txtValue = new FormControl('', { validators:[Validators.required] });
We can use this method to save using API. LearnersModules is the module file on our Angular files SaveSampleExams is the service file is one function method.
> this.service.SaveSampleExams(LearnersModules).subscribe(

> LearnersModules.txtValue = this.txtValue.value;
> });
This worked for me (i wanted to make id primary and set auto increment)
ALTER TABLE table_name
CHANGE id
id
INT PRIMARY KEY AUTO_INCREMENT;
Just a generic note. a way to keep it flexible.

I found that I had to discover the inside of the extension method I was trying to mock the input for, and mock what was going on inside the extension.
I viewed using an extension as adding code directly to your method. This meant I needed to mock what happens inside the extension rather than the extension itself.
That's because they serve different purposes and they both should be used not just one over the other.
The "alt" is for what you guys already said, so you can see what's the image it's all about if the image can't be displayed (for whatever reason), it also allows visually impaired people to understand what's the image about.
The "title" attribute is the correct one to show the tooltip with a title for the image.
There is obviously another process listening on the port. You might find out that process by using the following command:
$ lsof -i :8000
or change your tornado app's port. tornado's error info not Explicitly on this.
I have a Droid 3 (Verizon). I went to Motorola here and found the driver for the device 'Motorola ADB Interface' which was showing in device manager. It's kind of a big download for just the driver, but during installation it found it and installed correctly.
Just to add to RichieHindle's answer, check out Floatutorial, which walks you through how CSS floating and clearing works.
That looks fine, unless you want to pass it as Model string
public class HomeController : Controller
{
public ActionResult Index()
{
string model = "<HTML></HTML>";
return View(model);
}
}
@model string
@{
ViewBag.Title = "Index";
}
@Html.Raw(Model)
Many best explanations are here but I will try my best to simplify more.
Among all these methods, remove & pop are postfix while delete is prefix.
remove(): It used to remove first occurrence of element
remove(i)
=> first occurrence of i value
>>> a = [0, 2, 3, 2, 1, 4, 6, 5, 7]
>>> a.remove(2) # where i = 2
>>> a
[0, 3, 2, 1, 4, 6, 5, 7]
pop(): It used to remove element if:
unspecified
pop()
=> from end of list
>>>a.pop()
>>>a
[0, 3, 2, 1, 4, 6, 5]
specified
pop(index)
=> of index
>>>a.pop(2)
>>>a
[0, 3, 1, 4, 6, 5]
delete(): Its a prefix method.
Keep an eye on two different syntax for same method: [] and (). It possesses power to:
1.Delete index
del a[index]
=> used to delete index and its associated value just like pop.
>>>del a[1]
>>>a
[0, 1, 4, 6, 5]
2.Delete values in range [index 1:index N]
del a[0:3]
=> multiple values in range
>>>del a[0:3]
>>>a
[6, 5]
3.Last but not list, to delete whole list in one shot
del (a)
=> as said above.
>>>del (a)
>>>a
Hope this clarifies the confusion if any.

TL;DR Use GetProcessVersion
.
All of these function are available in Windows XP [desktop apps | UWP apps].
GetProcessVersion
uses a Process ID and returns 0 if the process of the given id is not running.
GetExitCodeProcess
uses a Process handle and gives you the process exit code, if the code is STILL_ACTIVE (259) the process is still running so you could check if it is not STILL_ACTIVE (259) meaning that the process is not running. This is likely to work in basically every situation, unless the process exits with code 259.
WaitForSingleObject
uses a Process handle with the SYNCHRONIZE access right and returns 0 if the process is not running. You should not specify INFINITE for the dwMilliseconds parameter because the function would not return until the process state became signaled(process is terminated).
def isPrime(y):
i=2
while i < y:
if y%i == 0 :
return 0
exit()

return 1

z=int(x)

if isPrime(n) == 1:
if count == z:

Related, so I thought I would post for others. If you want to find the UTC of the start of today (for your timezone) the following code works for any UTC offset (-23.5 thru +23.5). This looks like we add X hours then subtract X hours, but the important thing is the ".Date" after the add.
double utcOffset= 10.0; // Set to your UTC offset in hours (eg. Melbourne Australia)
var now = DateTime.UtcNow;
var startOfToday = now.AddHours(utcOffset - 24.0).Date;
startOfToday = startOfToday.AddHours(24.0 - utcOffset);

The component type of containers like vectors must be assignable. References are not assignable (you can only initialize them once when they are declared, and you cannot make them reference something else later). Other non-assignable types are also not allowed as components of containers, e.g. vector<const int>
is not allowed.

Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(
"<NSLayoutConstraint:0x2809b6760 'assistantHeight' TUISystemInputAssistantView:0x105710da0.height == 44 (active)>",
"<NSLayoutConstraint:0x2809ccff0 'assistantView.bottom' TUISystemInputAssistantView:0x105710da0.bottom == _UIKBCompatInputView:0x10525ae10.top (active)>",
"<NSLayoutConstraint:0x2809cccd0 'assistantView.top' V:|-(0)-[TUISystemInputAssistantView:0x105710da0] (active, names: '|':UIInputSetHostView:0x105215010 )>",
"<NSLayoutConstraint:0x2809ca300 'inputView.top' V:|-(0)-[_UIKBCompatInputView:0x10525ae10] (active, names: '|':UIInputSetHostView:0x105215010 )>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x2809ccff0 'assistantView.bottom' TUISystemInputAssistantView:0x105710da0.bottom == _UIKBCompatInputView:0x10525ae10.top (active)>
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.
With Java 8 it is possible to create a one-line answer even with older version of Mockito:
when(myMock.myFunction(anyString()).then(i -> i.getArgumentAt(0, String.class));
Of course this is not as useful as using AdditionalAnswers
suggested by David Wallace, but might be useful if you want to transform argument "on the fly".
Factory
and Service
is a just wrapper of a provider
.
Factory
Factory
can return anything which can be a class(constructor function)
, instance of class
, string
, number
or boolean
. If you return a constructor
function, you can instantiate in your controller.
myApp.factory('myFactory', function () {
// any logic here..
// Return any thing. Here it is object
return {
name: 'Joe'
}
}
Service
Service does not need to return anything. But you have to assign everything in this
variable. Because service will create instance by default and use that as a base object.
myApp.service('myService', function () {
// any logic here..
this.name = 'Joe';
}
Actual angularjs code behind the service
function service(name, constructor) {
return factory(name, ['$injector', function($injector) {
return $injector.instantiate(constructor);
}]);
}
It just a wrapper around the factory
. If you return something from service
, then it will behave like Factory
.
IMPORTANT
: The return result from Factory and Service will be cache and same will be returned for all controllers.
When should i use them?
Factory
is mostly preferable in all cases. It can be used when you have constructor
function which needs to be instantiated in different controllers.
Service
is a kind of Singleton
Object. The Object return from Service will be same for all controller. It can be used when you want to have single object for entire application.
Eg: Authenticated user details.
For further understanding, read

I tried to execute specific plugging right after clean up i.e. post-clean (default is clean phase). This worked for me with eclipse indigo. Just added post-clean resolved the problem for me.
<executions>
<execution>
<configuration>
</configuration>
<phase>post-clean</phase>
<goals>
<goal>update-widgetset</goal>
</goals>
</execution>
</executions>
Not sure why none of these seemed to work for me; the one that finally did it was:
$state.reload($state.current.name);
This was with Angular 1.4.0
There is actually a very conceptual basis for why this hasn't been implemented. It is a combination of basically 3 aspects:
These 3 together mean that by the time you have the text content you cannot ascend back to the containing element, and you cannot style the present text. This is likely significant as descending only allows for a singular tracking of context and SAX style parsing. Ascending or other selectors involving other axes introduce the need for more complex traversal or similar solutions that would greatly complicate the application of CSS to the DOM.
Try something like this:
var d = new Date();
d.setDate(d.getDate()-5);
Note that this modifies the date object and returns the time value of the updated date.
var d = new Date();_x000D_
_x000D_
document.write('Today is: ' + d.toLocaleString());_x000D_
_x000D_
d.setDate(d.getDate() - 5);_x000D_
_x000D_
document.write('<br>5 days ago was: ' + d.toLocaleString());
_x000D_
To check if the key exists (returns True
or False
)
'HOME' in os.environ
You can also use get()
when printing the key; useful if you want to use a default.
print(os.environ.get('HOME', '/home/username/'))
where /home/username/
is the default
Now i know ,the element is one of node
All node types in here"http://www.w3schools.com/dom/dom_nodetype.asp"
Element is between the start tag and end in the end tag
So text node is a node , but not a element.
This is from Apple doc
Classes and structures must set all of their stored properties to an appropriate initial value by the time an instance of that class or structure is created. Stored properties cannot be left in an indeterminate state.
You get the error message Class "HomeCell" has no initializers because your variables is in an indeterminate state. Either you create initializers or you make them optional types, using ! or ?
In your connection string replace server=localhost
with "server = Paul-PC\\SQLEXPRESS;
"
This all depends on what sort of access you have to your SAP system. An ABAP program that exports the data and/or an RFC that your macro can call to directly get the data or have SAP create the file is probably best.
However as a general rule people looking for this sort of answer are looking for an immediate solution that does not require their IT department to spend months customizing their SAP system.
In that case you probably want to use SAP GUI Scripting. SAP GUI scripting allows you to automate the Windows SAP GUI in much the same way as you automate Excel. In fact you can call the SAP GUI directly from an Excel macro. Read up more on it here. The SAP GUI has a macro recording tool much like Excel does. It records macros in VBScript which is nearly identical to Excel VBA and can usually be copied and pasted into an Excel macro directly.
Here is a simple example based on a SAP system I have access to.
Public Sub SimpleSAPExport()
Set SapGuiAuto = GetObject("SAPGUI") 'Get the SAP GUI Scripting object
Set SAPApp = SapGuiAuto.GetScriptingEngine 'Get the currently running SAP GUI
Set SAPCon = SAPApp.Children(0) 'Get the first system that is currently connected
Set session = SAPCon.Children(0) 'Get the first session (window) on that connection
'Start the transaction to view a table
session.StartTransaction "SE16"
'Select table T001
session.findById("wnd[0]/usr/ctxtDATABROWSE-TABLENAME").Text = "T001"
session.findById("wnd[0]/tbar[1]/btn[7]").Press
'Set our selection criteria
session.findById("wnd[0]/usr/txtMAX_SEL").text = "2"
session.findById("wnd[0]/tbar[1]/btn[8]").press
'Click the export to file button
session.findById("wnd[0]/tbar[1]/btn[45]").press
'Choose the export format
session.findById("wnd[1]/usr/subSUBSCREEN_STEPLOOP:SAPLSPO5:0150/sub:SAPLSPO5:0150/radSPOPLI-SELFLAG[1,0]").select
session.findById("wnd[1]/tbar[0]/btn[0]").press
'Choose the export filename
session.findById("wnd[1]/usr/ctxtDY_FILENAME").text = "test.txt"
session.findById("wnd[1]/usr/ctxtDY_PATH").text = "C:\Temp\"
'Export the file
session.findById("wnd[1]/tbar[0]/btn[0]").press
End Sub
To help find the names of elements such aswnd[1]/tbar[0]/btn[0]
you can use script recording.
Click the customize local layout button, it probably looks a bit like this:
Then find the Script Recording and Playback menu item.
Within that the More
button allows you to see/change the file that the VB Script is recorded to. The output format is a bit messy, it records things like selecting text, clicking inside a text field, etc.
The provided script should work if copied directly into a VBA macro. It uses late binding, the line Set SapGuiAuto = GetObject("SAPGUI")
defines the SapGuiAuto object.
If however you want to use early binding so that your VBA editor might show the properties and methods of the objects you are using, you need to add a reference to sapfewse.ocx
in the SAP GUI installation folder.
You can also try this approach save the keys and values in different list and then use dict method
data=['test1', '1', 'test2', '2', 'test3', '3', 'test4', '4']
keys=[]
values=[]
for i,j in enumerate(data):
if i%2==0:
keys.append(j)
else:
values.append(j)
print(dict(zip(keys,values)))
output:
{'test3': '3', 'test1': '1', 'test2': '2', 'test4': '4'}
What you want is a timer:
// RxJS v6+
import { timer } from 'rxjs';
//emit [1, 2, 3] after 1 second.
const source = timer(1000).map(([1, 2, 3]);
//output: [1, 2, 3]
const subscribe = source.subscribe(val => console.log(val));
I would do something like the following:
INSERT INTO cache VALUES (key, generation)
ON DUPLICATE KEY UPDATE (key = key, generation = generation + 1);
Setting the generation value to 0 in code or in the sql but the using the ON DUP... to increment the value. I think that's the syntax anyway.
tooltips: {
enabled: true,
mode: 'single',
callbacks: {
label: function(tooltipItems, data) {
return data.datasets[tooltipItems.datasetIndex].label+": "+tooltipItems.yLabel;
}
}
}
Your asp.net account {MACHINE}\ASPNET
does not have write access to that location. That is the reason why its failing.
Consider granting access rights to the resource to the ASP.NET request identity.
Right click on downloading folder Properties > Security Tab > Edit > Add > locations > choose your local machine > click OK > Type ASPNET below "Enter the object name to select" > Click Check Names
Check the boxes for the desired access (Full Control
). If it will not work for you do the same with Network Service
Now this should show your local {MACHINENAME}\ASPNET
account, then you set the write permission to this account.
Otherwise if the application is impersonating via <identity impersonate="true"/>
, the identity will be the anonymous user (typically IUSR_MACHINENAME
) or the authenticated request user.
Or just use dedicated location for storing files in ASP.NET which is App_Data
. To create it right click on your ASP.NET Project (in Visual Studio) Add > Add ASP.NET Folder > App_Data
. Then you'll be able to save data to this location:
var path = Server.MapPath("~/App_Data/file.txt");
System.IO.File.WriteAllText(path, "Hello World");
I 've tried a lot of examples but with Django mutagen plays nicely.
Example checking if files is mp3
from mutagen.mp3 import MP3, HeaderNotFoundError
try:
audio = MP3(file)
except HeaderNotFoundError:
raise ValidationError('This file should be mp3')
The downside is that your ability to check file types is limited, but it's a great way if you want not only check for file type but also to access additional information.
All of the example above should work just add a document ready action and change the order of how you perform the updates to the texts, also make sure your using Script manager alternatively non of this will work for you. Here is the text within the code behind.

Possibly an easier way?
Let's say justPrices is mixed up in terms of value, so you don't know where the smallest value is.
justPrices[0] = 4.5
justPrices[1] = 9.9
justPrices[2] = 1.5
Use sort.
justPrices.sort();
It would then put them in order for you. (Can also be done alphabetically.) The array then would be put in ascending order.
justPrices[0] = 1.5
justPrices[1] = 4.5
justPrices[2] = 9.9
You can then easily grab by the first index.
justPrices[0]
I find this is a bit more useful than what's proposed above because what if you need the lowest 3 numbers as an example? You can also switch which order they're arranged, more info at http://www.w3schools.com/jsref/jsref_sort.asp
You can use a kind of continue
by using a nested Do ... Loop While False
:
'This sample will output 1 and 3 only
Dim i As Integer
For i = 1 To 3: Do
If i = 2 Then Exit Do 'Exit Do is the Continue
Debug.Print i
Loop While False: Next i
There's no need to wait for input before closing, just change your command like so:
cmd /K python <script>
The /K
switch will execute the command that follows, but leave the command interpreter window open, in contrast to /C
, which executes and then closes.
Here is the alternative command:
gnuplot -p -e 'plot for [file in system("find . -name \\*.txt -depth 1")] file using 1:2 title file with lines'
it can do this for case statements as the values are compiler constants. An explanation in more detail is here http://sequence-points.blogspot.com/2007/10/why-is-switch-statement-faster-than-if.html
I know this is a little old, but I recently came across this while looking for a similar solution. Relying on hover events isn't good for responsive design, and especially terrible on mobile/touch screens. I ended up making a small edit to the dropdown.js file the allows you to click the menu item to open the menu and if you click the menu item again it will follow it.
The nice thing about this is it doesn't rely on hover at all and so it still works really nicely on a touch screen.
I've posted it here: https://github.com/mrhanlon/twbs-dropdown-doubletap/blob/master/js/dropdown-doubletap.js
Hope that helps!
npm ws was the answer for me. I found it less intrusive and more straight forward. With it was also trivial to mix websockets with rest services. Shared simple code on this post.
var WebSocketServer = require("ws").Server;
var http = require("http");
var express = require("express");
var port = process.env.PORT || 5000;
var app = express();
app.use(express.static(__dirname+ "/../"));
app.get('/someGetRequest', function(req, res, next) {
console.log('receiving get request');
});
app.post('/somePostRequest', function(req, res, next) {
console.log('receiving post request');
});
app.listen(80); //port 80 need to run as root
console.log("app listening on %d ", 80);
var server = http.createServer(app);
server.listen(port);
console.log("http server listening on %d", port);
var userId;
var wss = new WebSocketServer({server: server});
wss.on("connection", function (ws) {
console.info("websocket connection open");
var timestamp = new Date().getTime();
userId = timestamp;
ws.send(JSON.stringify({msgType:"onOpenConnection", msg:{connectionId:timestamp}}));
ws.on("message", function (data, flags) {
console.log("websocket received a message");
var clientMsg = data;
ws.send(JSON.stringify({msg:{connectionId:userId}}));
});
ws.on("close", function () {
console.log("websocket connection close");
});
});
console.log("websocket server created");
"py -m pip install requests" works fine with Windows and its up gradation. Just change the path after installing Python 3.4 in the command prompt and type in "py -m pip install requests"command prompt. pip install
Here is my way of doing stop() method:
Somewhere in code:
audioCh1: document.createElement("audio");
and then in stop():
this.audioCh1.pause()
this.audioCh1.src = 'data:audio/wav;base64,UklGRiQAAABXQVZFZm10IBAAAAABAAEAVFYAAFRWAAABAAgAZGF0YQAAAAA=';
In this way we don`t produce additional request, the old one is cancelled and our audio element is in clean state (tested in Chrome and FF) :>
Damir is correct,
Your subquery needs to ensure that dps_user.id equals um.profile_id, otherwise it will grab the top row which might, but probably not equal your id of 'u162231993'
Your query should look like this:
SELECT u.id, mbg.marker_value
FROM dps_user u
LEFT JOIN
(SELECT TOP 1 m.marker_value, um.profile_id
FROM dps_usr_markers um (NOLOCK)
INNER JOIN dps_markers m (NOLOCK)
ON m.marker_id= um.marker_id AND
m.marker_key = 'moneyBackGuaranteeLength'
WHERE u.id = um.profile_id
ORDER BY m.creation_date
) MBG ON MBG.profile_id=u.id
WHERE u.id = 'u162231993'
Just use special `
var lyrics = 'Never gonna give you up';
var html = `<div>${lyrics}</div>`;
You can see more examples here.
You need to use the android:background property , eg
android:background="@color/white"
Also you need to add a value for white in the strings.xml
<color name="white">#FFFFFF</color>
Edit : 18th Nov 2012
The first two letters of an 8 letter color code provide the alpha value, if you are using the html 6 letter color notation the color is opaque.
Eg :
Here's an example using the format()
function:
>>> "{:.2E}".format(Decimal('40800000000.00000000000000'))
'4.08E+10'
Instead of format, you can also use f-strings:
>>> f"{Decimal('40800000000.00000000000000'):.2E}"
'4.08E+10'
Try mvn clean install eclipse:eclipse -Dwtpversion=2.0 command on DOS command prompt. Suggesting you because , It worked for me!!
Yes using Option Explicit
is a good habit. Using .Select
however is not :) it reduces the speed of the code. Also fully justify sheet names else the code will always run for the Activesheet
which might not be what you actually wanted.
Is this what you are trying?
Option Explicit
Sub Sample()
Dim lastRow As Long, i As Long
Dim CopyRange As Range
'~~> Change Sheet1 to relevant sheet name
With Sheets("Sheet1")
lastRow = .Range("A" & .Rows.Count).End(xlUp).Row
For i = 2 To lastRow
If Len(Trim(.Range("A" & i).Value)) <> 0 Then
If CopyRange Is Nothing Then
Set CopyRange = .Rows(i)
Else
Set CopyRange = Union(CopyRange, .Rows(i))
End If
Else
Exit For
End If
Next
If Not CopyRange Is Nothing Then
'~~> Change Sheet2 to relevant sheet name
CopyRange.Copy Sheets("Sheet2").Rows(1)
End If
End With
End Sub
NOTE
If if you have data from Row 2 till Row 10 and row 11 is blank and then you have data again from Row 12 then the above code will only copy data from Row 2 till Row 10
If you want to copy all rows which have data then use this code.
Option Explicit
Sub Sample()
Dim lastRow As Long, i As Long
Dim CopyRange As Range
'~~> Change Sheet1 to relevant sheet name
With Sheets("Sheet1")
lastRow = .Range("A" & .Rows.Count).End(xlUp).Row
For i = 2 To lastRow
If Len(Trim(.Range("A" & i).Value)) <> 0 Then
If CopyRange Is Nothing Then
Set CopyRange = .Rows(i)
Else
Set CopyRange = Union(CopyRange, .Rows(i))
End If
End If
Next
If Not CopyRange Is Nothing Then
'~~> Change Sheet2 to relevant sheet name
CopyRange.Copy Sheets("Sheet2").Rows(1)
End If
End With
End Sub
Hope this is what you wanted?

To find the point where to add the -lm in Eclipse-IDE is really horrible, so it took me some time.
If someone else also uses Edlipse, here's the way how to add the command:
Project -> Properties -> C/C++ Build -> Settings -> GCC C Linker -> Miscelleaneous -> Linker flags: in this field add the command -lm
When using percentage, the height it relative to the width and will dynamically change along with it:
chart: {
height: (9 / 16 * 100) + '%' // 16:9 ratio
},
