You can do that like this:
from datetime import datetime
from threading import Timer
x=datetime.today()
y=x.replace(day=x.day+1, hour=1, minute=0, second=0, microsecond=0)
delta_t=y-x
secs=delta_t.seconds+1
def hello_world():
print "hello world"
#...
t = Timer(secs, hello_world)
t.start()
This will execute a function (eg. hello_world) in the next day at 1a.m.
EDIT:
As suggested by @PaulMag, more generally, in order to detect if the day of the month must be reset due to the reaching of the end of the month, the definition of y in this context shall be the following:
y = x.replace(day=x.day, hour=1, minute=0, second=0, microsecond=0) + timedelta(days=1)
With this fix, it is also needed to add timedelta to the imports. The other code lines maintain the same. The full solution, using also the total_seconds() function, is therefore:
from datetime import datetime, timedelta
from threading import Timer
x=datetime.today()
y = x.replace(day=x.day, hour=1, minute=0, second=0, microsecond=0) + timedelta(days=1)
delta_t=y-x
secs=delta_t.total_seconds()
def hello_world():
print "hello world"
#...
t = Timer(secs, hello_world)
t.start()
The documentation on CREATE EVENT is quite good, but it takes a while to get it right.
You have two problems, first, making the event recur, second, making it run at 13:00 daily.
This example creates a recurring event.
CREATE EVENT e_hourly
ON SCHEDULE
EVERY 1 HOUR
COMMENT 'Clears out sessions table each hour.'
DO
DELETE FROM site_activity.sessions;
When in the command-line MySQL client, you can:
SHOW EVENTS;
This lists each event with its metadata, like if it should run once only, or be recurring.
The second problem: pointing the recurring event to a specific schedule item.
By trying out different kinds of expression, we can come up with something like:
CREATE EVENT IF NOT EXISTS `session_cleaner_event`
ON SCHEDULE
EVERY 13 DAY_HOUR
COMMENT 'Clean up sessions at 13:00 daily!'
DO
DELETE FROM site_activity.sessions;
For non-preemptive system,
waitingTime = startTime - arrivalTime
turnaroundTime = burstTime + waitingTime = finishTime- arrivalTime
startTime = Time at which the process started executing
finishTime = Time at which the process finished executing
You can keep track of the current time elapsed in the system(timeElapsed
). Assign all processors to a process in the beginning, and execute until the shortest process is done executing. Then assign this processor which is free to the next process in the queue. Do this until the queue is empty and all processes are done executing. Also, whenever a process starts executing, recored its startTime
, when finishes, record its finishTime
(both same as timeElapsed
). That way you can calculate what you need.
I'm also running XP SP2, and this works perfectly (from the command line...):
start control schedtasks
Using pexpect with non-blocking readlines is another way to do this. Pexpect solves the deadlock problems, allows you to easily run the processes in the background, and gives easy ways to have callbacks when your process spits out predefined strings, and generally makes interacting with the process much easier.
I hope I understand your question correctly: assuming that the values are of type String
, the most efficient way is probably to convert to a HashSet
and iterate over it:
ArrayList<String> values = ... //Your values
HashSet<String> uniqueValues = new HashSet<>(values);
for (String value : uniqueValues) {
... //Do something
}
If you want the second highest number you can use
=LARGE(E4:E9;2)
although that doesn't account for duplicates so you could get the same result as the Max
If you want the largest number that is smaller than the maximum number you can use this version
=LARGE(E4:E9;COUNTIF(E4:E9;MAX(E4:E9))+1)
In my case, I've loaded both the js
and css
visjs
files using the above technique - which works great. I call the new function from ngOnInit()
Note: I could not get it to load by simply adding a <script>

Instructions for Drupal 8 / FontAwesome 5
Create a YOUR_THEME_NAME_HERE.THEME file and place it in your themes directory (ie. your_site_name/themes/your_theme_name)
Paste this into the file, it is PHP code to find the Search Block and change the value to the UNICODE for the FontAwesome icon. You can find other characters at this link https://fontawesome.com/cheatsheet.
<?php
function YOUR_THEME_NAME_HERE_form_search_block_form_alter(&$form, &$form_state) {
$form['keys']['#attributes']['placeholder'][] = t('Search');
$form['actions']['submit']['#value'] = html_entity_decode('');
}
?>
Open the CSS file of your theme (ie. your_site_name/themes/your_theme_name/css/styles.css) and then paste this in which will change all input submit text to FontAwesome. Not sure if this will work if you also want to add text in the input button though for just an icon it is fine.
Make sure you import FontAwesome, add this at the top of the CSS file
@import url('https://use.fontawesome.com/releases/v5.0.9/css/all.css');
then add this in the CSS
input#edit-submit {
font-family: 'Font Awesome\ 5 Free';
background-color: transparent;
border: 0;
}
FLUSH ALL CACHES AND IT SHOULD WORK FINE
Add Google Font Effects
If you are using Google Web Fonts as well you can add also add effects to the icon (see more here https://developers.google.com/fonts/docs/getting_started#enabling_font_effects_beta). You need to import a Google Web Font including the effect(s) you would like to use first in the CSS so it will be
@import url('https://fonts.googleapis.com/css?family=Open+Sans:400,800&effect=3d-float');
@import url('https://use.fontawesome.com/releases/v5.0.9/css/all.css');
Then go back to your .THEME file and add the class for the 3D Float Effect so the code will now add a class to the input. There are different effects available. So just choose the effect you like, change the CSS for the font import and the change the value FONT-EFFECT-3D-FLOAT int the code below to font-effect-WHATEVER_EFFECT_HERE. Note effects are still in Beta and don't work in all browsers so read here before you try it https://developers.google.com/fonts/docs/getting_started#enabling_font_effects_beta
<?php
function YOUR_THEME_NAME_HERE_form_search_block_form_alter(&$form, &$form_state) {
$form['keys']['#attributes']['placeholder'][] = t('Search');
$form['actions']['submit']['#value'] = html_entity_decode('');
$form['actions']['submit']['#attributes']['class'][] = 'font-effect-3d-float';
}
?>
There are a few differences between Temporary Tables (#tmp) and Table Variables (@tmp), although using tempdb isn't one of them, as spelt out in the MSDN link below.
As a rule of thumb, for small to medium volumes of data and simple usage scenarios you should use table variables. (This is an overly broad guideline with of course lots of exceptions - see below and following articles.)
Some points to consider when choosing between them:
Temporary Tables are real tables so you can do things like CREATE INDEXes, etc. If you have large amounts of data for which accessing by index will be faster then temporary tables are a good option.
Table variables can have indexes by using PRIMARY KEY or UNIQUE constraints. (If you want a non-unique index just include the primary key column as the last column in the unique constraint. If you don't have a unique column, you can use an identity column.) SQL 2014 has non-unique indexes too.
Table variables don't participate in transactions and SELECT
s are implicitly with NOLOCK
. The transaction behaviour can be very helpful, for instance if you want to ROLLBACK midway through a procedure then table variables populated during that transaction will still be populated!
Temp tables might result in stored procedures being recompiled, perhaps often. Table variables will not.
You can create a temp table using SELECT INTO, which can be quicker to write (good for ad-hoc querying) and may allow you to deal with changing datatypes over time, since you don't need to define your temp table structure upfront.
You can pass table variables back from functions, enabling you to encapsulate and reuse logic much easier (eg make a function to split a string into a table of values on some arbitrary delimiter).
Using Table Variables within user-defined functions enables those functions to be used more widely (see CREATE FUNCTION documentation for details). If you're writing a function you should use table variables over temp tables unless there's a compelling need otherwise.
Both table variables and temp tables are stored in tempdb. But table variables (since 2005) default to the collation of the current database versus temp tables which take the default collation of tempdb (ref). This means you should be aware of collation issues if using temp tables and your db collation is different to tempdb's, causing problems if you want to compare data in the temp table with data in your database.
Global Temp Tables (##tmp) are another type of temp table available to all sessions and users.

Another option would be to just use perl with globstar.
Enabling shopt -s globstar
in your .bashrc
(or wherever) allows the **
glob pattern to match all sub-directories and files recursively.
Thus using perl -pXe 's/SEARCH/REPLACE/g' -i **
will recursively
replace SEARCH
with REPLACE
.
The -X
flag tells perl to "disable all warnings" - which means that
it won't complain about directories.
The globstar also allows you to do things like sed -i 's/SEARCH/REPLACE/g' **/*.ext
if you wanted to replace SEARCH
with REPLACE
in all child files with the extension .ext
.
You may also have a look on Runtyper - a tool that performs type checking of operands in ===
(and other operations).
For your example, if you have strict comparison x === y
and x = 123, y = "123"
, it will automatically check typeof x, typeof y
and show warning in console:
Strict compare of different types: 123 (number) === "123" (string)
Try putting this HTML snippet into your served document:
<img id="ItemPreview" src="">
Then, on JavaScript side, you can dynamically modify image's src
attribute with so-called Data URL.
document.getElementById("ItemPreview").src = "data:image/png;base64," + yourByteArrayAsBase64;
Alternatively, using jQuery:
$('#ItemPreview').attr('src', `data:image/png;base64,${yourByteArrayAsBase64}`);
This assumes that your image is stored in PNG format, which is quite popular. If you use some other image format (e.g. JPEG), modify the MIME type ("image/..."
part) in the URL accordingly.

My friend... there is a way but "hack" does not begin to describe it. You have to basically exploit a bug in IE 6 & 7.
Works every time!
Instead of calling window.close()
, redirect to another page.
Opening Page:
alert("No whammies!");

I was with the same problem and now discovered a working solution. After successful installation of node and angular CLI do the following steps.

It is not necessary to use withRouter. This works for me:
In your parent page,
<BrowserRouter>
<Switch>
<Route path="/routeA" render={(props)=> (
<ComponentA {...props} propDummy={50} />
)} />
<Route path="/routeB" render={(props)=> (
<ComponentB {...props} propWhatever={100} />
)} />
</Switch>
</BrowserRouter>
Then in ComponentA or ComponentB you can access
this.props.history
object, including the this.props.history.push method.
Actually we can do it. we can set the file value default by using webbrowser control in c# using FormToMultipartPostData Library.We have to download and include this Library in our project. Webbrowser enables the user to navigate Web pages inside form. Once the web page loaded , the script inside the webBrowser1_DocumentCompleted will be executed. So,
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
FormToMultipartPostData postData =
new FormToMultipartPostData(webBrowser1, form);
postData.SetFile("fileField", @"C:\windows\win.ini");
postData.Submit();
}

Those two replaceAll
calls will always produce the same result, regardless of what x
is. However, it is important to note that the two regular expressions are not the same:
\\s
- matches single whitespace character \\s+
- matches sequence of one or more whitespace characters.In this case, it makes no difference, since you are replacing everything with an empty string (although it would be better to use \\s+
from an efficiency point of view). If you were replacing with a non-empty string, the two would behave differently.
To build on Ilya's answer try the following query:
SELECT MSysObjects.Name AS table_name
FROM MSysObjects
WHERE (((Left([Name],1))<>"~")
AND ((Left([Name],4))<>"MSys")
AND ((MSysObjects.Type) In (1,4,6)))
order by MSysObjects.Name
(this one works without modification with an MDB)
ACCDB users may need to do something like this
SELECT MSysObjects.Name AS table_name
FROM MSysObjects
WHERE (((Left([Name],1))<>"~")
AND ((Left([Name],4))<>"MSys")
AND ((MSysObjects.Type) In (1,4,6))
AND ((MSysObjects.Flags)=0))
order by MSysObjects.Name
As there is an extra table is included that appears to be a system table of some sort.
You mean like this?

Nearly every answer here states that this can only be caused by an infinite loop. That's not true, you could otherwise over-run the stack through deeply nested calls (not to say that's efficient, but it's certainly in the realm of possible). If you have control of your JavaScript VM, you can adjust the stack size. For example:
node --stack-size=2000
See also: How can I increase the maximum call stack size in Node.js
Redis supports 5 data types. You need to know what type of value that a key maps to, as for each data type, the command to retrieve it is different.
Here are the commands to retrieve key value:
<key>
<key>
<key> <start> <end>
<key>
<key> <min> <max>
Use the TYPE
command to check the type of value a key is mapping to:
<key>
In Robins's answer ends-with is not supported in xpath 1.0 too.. Only starts-with is supported... So if your condition is not very specific..You can Use like this which worked for me
//*[starts-with(@id,'sometext') and contains(@name,'_text')]`\
echo date("l M j, Y",$res1['timep']);
This is really good for converting a unix timestamp to a readable date along with day. Example:
Thursday Jul 7, 2016
\path-to-your-android-sdk-folder\platforms\android-xx\data\res
n = abs(number);
result = 1;
if (n mod 2 == 0) {
result = 2;
while (n mod 2 = 0) n /= 2;
}
for(i=3; i<sqrt(n); i+=2) {
if (n mod i == 0) {
result = i;
while (n mod i = 0) n /= i;
}
}
return max(n,result)
There are some modulo tests that are superflous, as n can never be divided by 6 if all factors 2 and 3 have been removed. You could only allow primes for i, which is shown in several other answers here.
You could actually intertwine the sieve of Eratosthenes here:

Change the return type of your GetResults to be List<Person>
.
Eliminate the code that you use to serialize the List to a json string - WCF does this for you automatically.
Using your definition for the Person class, this code works for me:
public List<Person> GetPlayers()
{
List<Person> players = new List<Person>();
players.Add(new Person { FirstName="Peyton", LastName="Manning", Age=35 } );
players.Add(new Person { FirstName="Drew", LastName="Brees", Age=31 } );
players.Add(new Person { FirstName="Brett", LastName="Favre", Age=58 } );
return players;
}
results:
[{"Age":35,"FirstName":"Peyton","LastName":"Manning"},
{"Age":31,"FirstName":"Drew","LastName":"Brees"},
{"Age":58,"FirstName":"Brett","LastName":"Favre"}]
(All on one line)
I also used this attribute on the method:
[WebInvoke(Method = "GET",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
UriTemplate = "players")]
WebInvoke with Method= "GET" is the same as WebGet, but since some of my methods are POST, I use all WebInvoke for consistency.
The UriTemplate sets the URL at which the method is available. So I can do a GET on
http://myserver/myvdir/JsonService.svc/players
and it just works.
Also check out IIRF or another URL rewriter to get rid of the .svc in the URI.
This specific example will just check for inputs but you could tweak it however, Add something like this to your .ajax function:
beforeSend: function() {
$empty = $('form#yourForm').find("input").filter(function() {
return this.value === "";
});
if($empty.length) {
alert('You must fill out all fields in order to submit a change');
return false;
}else{
return true;
};
},

You can create a detached master branch using only porcelain Git commands:
git init
touch GO_AWAY
git add GO_AWAY
git commit -m "GO AWAY - this branch is detached from reality"
That gives us a master branch with a rude message (you may want to be more polite). Now we create our "real" branch (let's call it trunk in honour of SVN) and divorce it from master:
git checkout -b trunk
git rm GO_AWAY
git commit --amend --allow-empty -m "initial commit on detached trunk"
Hey, presto! gitk --all will show master and trunk with no link between them.
The "magic" here is that --amend causes git commit to create a new commit with the same parent as the current HEAD, then make HEAD point to it. But the current HEAD doesn't have a parent as it's the initial commit in the repository, so the new HEAD doesn't get one either, making them detached from each other.
The old HEAD commit doesn't get deleted by git-gc because refs/heads/master still points to it.
The --allow-empty flag is only needed because we're committing an empty tree. If there were some git add's after the git rm then it wouldn't be necessary.
In truth, you can create a detached branch at any time by branching the initial commit in the repository, deleting its tree, adding your detached tree, then doing git commit --amend.
I know this doesn't answer the question of how to modify the default branch on the remote repository, but it gives a clean answer on how to create a detached branch.
Best way is to use the Carbon dependency.
With Carbon\Carbon::now();
you get the current Datetime.
With Carbon you can do like enything with the DateTime. Event things like this:
$tomorrow = Carbon::now()->addDay();
$lastWeek = Carbon::now()->subWeek();

To create a "drop down menu" you can use OptionMenu
in tkinter
Example of a basic OptionMenu
:
from Tkinter import *
master = Tk()
variable = StringVar(master)
variable.set("one") # default value
w = OptionMenu(master, variable, "one", "two", "three")
w.pack()
mainloop()
More information (including the script above) can be found here.
Creating an OptionMenu
of the months from a list would be as simple as:
from tkinter import *
OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc
master = Tk()
variable = StringVar(master)
variable.set(OPTIONS[0]) # default value
w = OptionMenu(master, variable, *OPTIONS)
w.pack()
mainloop()
In order to retrieve the value the user has selected you can simply use a .get()
on the variable that we assigned to the widget, in the below case this is variable
:
from tkinter import *
OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc
master = Tk()
variable = StringVar(master)
variable.set(OPTIONS[0]) # default value
w = OptionMenu(master, variable, *OPTIONS)
w.pack()
def ok():
print ("value is:" + variable.get())
button = Button(master, text="OK", command=ok)
button.pack()
mainloop()
I would highly recommend reading through this site for further basic tkinter information as the above examples are modified from that site.
Use sed:
MYVAR=ho02123ware38384you443d34o3434ingtod38384day
echo "$MYVAR" | sed -e 's/[a-zA-Z]/X/g' -e 's/[0-9]/N/g'
# prints XXNNNNNXXXXNNNNNXXXNNNXNNXNNNNXXXXXXNNNNNXXX
Note that the subsequent -e
's are processed in order. Also, the g
flag for the expression will match all occurrences in the input.
You can also pick your favorite tool using this method, i.e. perl, awk, e.g.:
echo "$MYVAR" | perl -pe 's/[a-zA-Z]/X/g and s/[0-9]/N/g'
This may allow you to do more creative matches... For example, in the snip above, the numeric replacement would not be used unless there was a match on the first expression (due to lazy and
evaluation). And of course, you have the full language support of Perl to do your bidding...
git log -p
will generate the a patch (the diff) for every commit selected. For a single file, use git log --follow -p $file
.
If you're looking for a particular change, use git bisect
to find the change in log(n) views by splitting the number of commits in half until you find where what you're looking for changed.
Also consider looking back in history using git blame
to follow changes to the line in question if you know what that is. This command shows the most recent revision to affect a certain line. You may have to go back a few versions to find the first change where something was introduced if somebody has tweaked it over time, but that could give you a good start.
Finally, gitk
as a GUI does show me the patch immediately for any commit I click on.
Example :
.complete
+ callback
This is a standards compliant method without extra dependencies, and waits no longer than necessary:
var img = document.querySelector('img')
function loaded() {
alert('loaded')
}
if (img.complete) {
loaded()
} else {
img.addEventListener('load', loaded)
img.addEventListener('error', function() {
alert('error')
})
}

Use LXML. LXML uses the full power of libxml2 and libxslt, but wraps them in more "Pythonic" bindings than the Python bindings that are native to those libraries. As such, it gets the full XPath 1.0 implementation. Native ElemenTree supports a limited subset of XPath, although it may be good enough for your needs.
The customary method for doing this sort of thing is to "print to string". In C++ that means using std::stringstream
something like:
std::stringstream ss;
ss << std::fixed << std::setprecision(2) << number;
std::string mystring = ss.str();
I know this is an old question, but someone should have mentioned the compile-time macros in Availability.h
. All of the other methods here are runtime solutions, and will not work in a header file, class category, or ivar definition.

Actually, it appears that urllib2 can do an HTTP HEAD request.
The question that @reto linked to, above, shows how to get urllib2 to do a HEAD request.
Here's my take on it:
import urllib2
# Derive from Request class and override get_method to allow a HEAD request.
class HeadRequest(urllib2.Request):
def get_method(self):
return "HEAD"
myurl = 'http://bit.ly/doFeT'
request = HeadRequest(myurl)

If you check this with something like the Wireshark network protocol analazer, you can see that it is actually sending out a HEAD request, rather than a GET.
This is the HTTP request and response from the code above, as captured by Wireshark:
HEAD /doFeT HTTP/1.1
Accept-Encoding: identity
Host: bit.ly
Connection: close
User-Agent: Python-urllib/2.7HTTP/1.1 301 Moved
Server: nginx
Date: Sun, 19 Feb 2012 13:20:56 GMT
Content-Type: text/html; charset=utf-8
Cache-control: private; max-age=90
Location: http://www.kidsidebyside.org/?p=445
MIME-Version: 1.0
Content-Length: 127
Connection: close
Set-Cookie: _bit=4f40f738-00153-02ed0-421cf10a;domain=.bit.ly;expires=Fri Aug 17 13:20:56 2012;path=/; HttpOnly
However, as mentioned in one of the comments in the other question, if the URL in question includes a redirect then urllib2 will do a GET request to the destination, not a HEAD. This could be a major shortcoming, if you really wanted to only make HEAD requests.
The request above involves a redirect. Here is request to the destination, as captured by Wireshark:
GET /2009/05/come-and-draw-the-circle-of-unity-with-us/ HTTP/1.1
Accept-Encoding: identity
Host: www.kidsidebyside.org
Connection: close
User-Agent: Python-urllib/2.7
An alternative to using urllib2 is to use Joe Gregorio's httplib2 library:
import httplib2
url = "http://bit.ly/doFeT"
http_interface = httplib2.Http()
try:
response, content = http_interface.request(url, method="HEAD")
print ("Response status: %d - %s" % (response.status, response.reason))
# This will just display all the dictionary key-value pairs. Replace this
# line with something useful.
response.__dict__
except httplib2.ServerNotFoundError, e:
print (e.message)
This has the advantage of using HEAD requests for both the initial HTTP request and the redirected request to the destination URL.
Here's the first request:
HEAD /doFeT HTTP/1.1
Host: bit.ly
accept-encoding: gzip, deflate
user-agent: Python-httplib2/0.7.2 (gzip)
Here's the second request, to the destination:
HEAD /2009/05/come-and-draw-the-circle-of-unity-with-us/ HTTP/1.1
Host: www.kidsidebyside.org
accept-encoding: gzip, deflate
user-agent: Python-httplib2/0.7.2 (gzip)
When writing CMake scripts there is a lot you need to know about the syntax and how to use variables in CMake.
Strings using set()
:
set(MyString "Some Text")
set(MyStringWithVar "Some other Text: ${MyString}")
set(MyStringWithQuot "Some quote: \"${MyStringWithVar}\"")
Or with string()
:
string(APPEND MyStringWithContent " ${MyString}")
Lists using set()
:
set(MyList "a" "b" "c")
set(MyList ${MyList} "d")
Or better with list()
:
list(APPEND MyList "a" "b" "c")
list(APPEND MyList "d")
Lists of File Names:
set(MySourcesList "File.name" "File with Space.name")
list(APPEND MySourcesList "File.name" "File with Space.name")
add_excutable(MyExeTarget ${MySourcesList})
set()
Commandstring()
Commandlist()
CommandFirst there are the "Normal Variables" and things you need to know about their scope:
CMakeLists.txt
they are set in and everything called from there (add_subdirectory()
, include()
, macro()
and function()
).add_subdirectory()
and function()
commands are special, because they open-up their own scope.
set(...)
there are only visible there and they make a copy of all normal variables of the scope level they are called from (called parent scope).set(... PARENT_SCOPE)
function(xyz _resultVar)
is setting set(${_resultVar} 1 PARENT_SCOPE)
include()
or macro()
scripts will modify variables directly in the scope of where they are called from. Second there is the "Global Variables Cache". Things you need to know about the Cache:
CMakeCache.txt
file in your binary output directory.The values in the Cache can be modified in CMake's GUI application before they are generated. Therefore they - in comparison to normal variables - have a type
and a docstring
. I normally don't use the GUI so I use set(... CACHE INTERNAL "")
to set my global and persistant values.
Please note that the INTERNAL
cache variable type does imply FORCE
In a CMake script you can only change existing Cache entries if you use the set(... CACHE ... FORCE)
syntax. This behavior is made use of e.g. by CMake itself, because it normally does not force Cache entries itself and therefore you can pre-define it with another value.
cmake -D var:type=value
, just cmake -D var=value
or with cmake -C CMakeInitialCache.cmake
.unset(... CACHE)
.The Cache is global and you can set them virtually anywhere in your CMake scripts. But I would recommend you think twice about where to use Cache variables (they are global and they are persistant). I normally prefer the set_property(GLOBAL PROPERTY ...)
and set_property(GLOBAL APPEND PROPERTY ...)
syntax to define my own non-persistant global variables.
To avoid pitfalls you should know the following about variables:
find_...
commands - if successful - do write their results as cached variables "so that no call will search again"set(MyVar a b c)
is "a;b;c"
and set(MyVar "a b c")
is "a b c"
list()
command for handling listsfunctions()
instead of macros()
because you don't want your local variables to show up in the parent scope. project()
and enable_language()
calls. So it could get important to set some variables before those commands are used.Sometimes only debugging variables helps. The following may help you:
printf
debugging style by using the message()
command. There also some ready to use modules shipped with CMake itself: CMakePrintHelpers.cmake, CMakePrintSystemInformation.cmakeCMakeCache.txt
file in your binary output directory. This file is even generated if the actual generation of your make environment fails.cmake --trace ...
to see the CMake's complete parsing process. That's sort of the last reserve, because it generates a lot of output.$ENV{...}
and write set(ENV{...} ...)
environment variables$<...>
are only evaluated when CMake's generator writes the make environment (it comparison to normal variables that are replaced "in-place" by the parser)${${...}}
you can give variable names in a variable and reference its content.if()
command)
if(MyVariable)
you can directly check a variable for true/false (no need here for the enclosing ${...}
)1
, ON
, YES
, TRUE
, Y
, or a non-zero number. 0
, OFF
, NO
, FALSE
, N
, IGNORE
, NOTFOUND
, the empty string, or ends in the suffix -NOTFOUND
.if(MSVC)
, but it can be confusing for someone who does not know this syntax shortcut.set(CMAKE_${lang}_COMPILER ...)
if()
commands. Here is an example where CMAKE_CXX_COMPILER_ID
is "MSVC"
and MSVC
is "1"
:
if("${CMAKE_CXX_COMPILER_ID}" STREQUAL "MSVC")
is true, because it evaluates to if("1" STREQUAL "1")
if(CMAKE_CXX_COMPILER_ID STREQUAL "MSVC")
is false, because it evaluates to if("MSVC" STREQUAL "1")
if(MSVC)
cmake_policy(SET CMP0054 NEW)
to "only interpret if()
arguments as variables or keywords when unquoted."option()
command
ON
or OFF
and they allow some special handling like e.g. dependenciesoption
with the set
command. The value given to option
is really only the "initial value" (transferred once to the cache during the first configuration step) and is afterwards meant to be changed by the user through CMake's GUI.The method has been renamed to findById(…)
returning an Optional
so that you have to handle absence yourself:
Optional<Foo> result = repository.findById(…);
result.ifPresent(it -> …); // do something with the value if present
result.map(it -> …); // map the value if present
Foo foo = result.orElse(null); // if you want to continue just like before
There's a really nice easy way to do this in Macintosh OsX. A fellow has made a quicklook plugin (command-space) that renders .mat formats so you can view the variables inside etc. Quite useful! https://github.com/jaketmp/matlab-quicklook/releases

I combined previous answers and used structure of Win32_PnPEntity class which can be found found here. Got solution like this:
using System.Management;
public static void Main()

public string GetPortInformation()
{
ManagementClass processClass = new ManagementClass("Win32_PnPEntity");
ManagementObjectCollection Ports = processClass.GetInstances();
foreach (ManagementObject property in Ports)
{
var name = property.GetPropertyValue("Name");
if (name != null && name.ToString().Contains("USB") && name.ToString().Contains("COM"))
{
var portInfo = new SerialPortInfo(property);
//Thats all information i got from port.
//Do whatever you want with this information
}
}
return string.Empty;
}
SerialPortInfo class:
public class SerialPortInfo
{
public SerialPortInfo(ManagementObject property)
{
this.Availability = property.GetPropertyValue("Availability") as int? ?? 0;
this.Caption = property.GetPropertyValue("Caption") as string ?? string.Empty;
this.ClassGuid = property.GetPropertyValue("ClassGuid") as string ?? string.Empty;

this.ErrorDescription = property.GetPropertyValue("ErrorDescription") as string ?? string.Empty;
this.HardwareID = property.GetPropertyValue("HardwareID") as string[] ?? new string[] { };
this.InstallDate = property.GetPropertyValue("InstallDate") as DateTime? ?? DateTime.MinValue;

this.SystemName = property.GetPropertyValue("SystemName") as string ?? string.Empty;
}
int Availability;

Why would you use -z? To test if a string is non-empty, you typically use -n:
if test -n "$errorstatus"; then echo errorstatus is not empty fi
$num + 0
does the trick.
echo 125.00 + 0; // 125
echo '125.00' + 0; // 125
echo 966.70 + 0; // 966.7
Internally, this is equivalent to casting to float with (float)$num
or floatval($num)
but I find it simpler.
Anonymous ftp logins are usually the username 'anonymous' with the user's email address as the password. Some servers parse the password to ensure it looks like an email address.
User: anonymous
Password: [email protected]
in this case use git add and integrate all pending files and then use git commit and then git push
git add - integrate all pedent files
git commit - save the commit
git push - save to repository

1.2975118E7
is scientific notation.
1.2975118E7 = 1.2975118 * 10^7 = 12975118
Also, Math.round(f)
returns an integer. You can't use it to get your desired format x.xx
.
You could use String.format
.
String s = String.format("%.2f", 1.2975118);

As the Visual C# Program Manager linked above says, there are limited situations where the With statement is more efficient, the example he gives when it is being used as a shorthand to repeatedly access a complex expression.
Using an extension method and generics you can create something that is vaguely equivalent to a With statement, by adding something like this:
public static T With<T>(this T item, Action<T> action)
{
action(item);
return item;
}
Taking a simple example of how it could be used, using lambda syntax you can then use it to change something like this:
updateRoleFamily.RoleFamilyDescription = roleFamilyDescription;
updateRoleFamily.RoleFamilyCode = roleFamilyCode;
To this:
updateRoleFamily.With(rf =>
{
rf.RoleFamilyDescription = roleFamilyDescription;
rf.RoleFamilyCode = roleFamilyCode;
});
On an example like this, the only advantage is perhaps a nicer layout, but with a more complex reference and more properties, it could well give you more readable code.

What happens with bittorrent and a DHT is that at the beginning bittorrent uses information embedded in the torrent file to go to either a tracker or one of a set of nodes from the DHT. Then once it finds one node, it can continue to find others and persist using the DHT without needing a centralized tracker to maintain it.
The original information bootstraps the later use of the DHT.

REST means working with the standards of the web, and the standard for "secure" transfer on the web is SSL. Anything else is going to be kind of funky and require extra deployment effort for clients, which will have to have encryption libraries available.
Once you commit to SSL, there's really nothing fancy required for authentication in principle. You can again go with web standards and use HTTP Basic auth (username and secret token sent along with each request) as it's much simpler than an elaborate signing protocol, and still effective in the context of a secure connection. You just need to be sure the password never goes over plain text; so if the password is ever received over a plain text connection, you might even disable the password and mail the developer. You should also ensure the credentials aren't logged anywhere upon receipt, just as you wouldn't log a regular password.
HTTP Digest is a safer approach as it prevents the secret token being passed along; instead, it's a hash the server can verify on the other end. Though it may be overkill for less sensitive applications if you've taken the precautions mentioned above. After all, the user's password is already transmitted in plain-text when they log in (unless you're doing some fancy JavaScript encryption in the browser), and likewise their cookies on each request.
Note that with APIs, it's better for the client to be passing tokens - randomly generated strings - instead of the password the developer logs into the website with. So the developer should be able to log into your site and generate new tokens that can be used for API verification.
The main reason to use a token is that it can be replaced if it's compromised, whereas if the password is compromised, the owner could log into the developer's account and do anything they want with it. A further advantage of tokens is you can issue multiple tokens to the same developers. Perhaps because they have multiple apps or because they want tokens with different access levels.
(Updated to cover implications of making the connection SSL-only.)
Five options:
Use the free jsonutils web tool without installing anything.
If you have Web Essentials in Visual Studio, use Edit > Paste special > paste JSON as class.
Use the free jsonclassgenerator.exe
The web tool app.quicktype.io does not require installing anything.
The web tool json2csharp also does not require installing anything.
Pros and Cons:
jsonclassgenerator converts to PascalCase but the others do not.
app.quicktype.io has some logic to recognize dictionaries and handle JSON properties whose names are invalid c# identifiers.

"jdk1.8.0_111" beeing the name of the java configuration initially registered into Jenkins

Found a solution:
mysql> UPDATE table SET last_update=now(), last_monitor=last_update WHERE id=1;
I found this in MySQL Docs and after a few tests it works:
the following statement sets col2 to the current (updated) col1 value, not the original col1 value. The result is that col1 and col2 have the same value. This behavior differs from standard SQL.
UPDATE t1 SET col1 = col1 + 1, col2 = col1;
Code for Find the Column Name same as using the Like
in sql.
foreach (DataGridViewColumn column in GrdMarkBook.Columns)
//GrdMarkBook is Data Grid name
{
string HeaderName = column.HeaderText.ToString();
// This line Used for find any Column Have Name With Exam
if (column.HeaderText.ToString().ToUpper().Contains("EXAM"))
{
int CoumnNo = column.Index;
}
}
You can also use
document.add(new Paragraph());
document.add(new Paragraph());
before seperator if you are using either it is fine.
ACCESS_COARSE_LOCATION

) and see if you have them (using checkSelfPermission()
).
One workaround in the short term is to drop your targetSdkVersion
below 23.
But, eventually, you will want to update your app to use the runtime permission system.
For example, this activity works with five permissions. Four are runtime permissions, though it is presently only handling three (I wrote it before WRITE_EXTERNAL_STORAGE
was added to the runtime permission roster).

(from this sample project)
For the requestPermissions() function, should the parameters just be "ACCESS_COARSE_LOCATION"? Or should I include the full name "android.permission.ACCESS_COARSE_LOCATION"?
I would use the constants defined on Manifest.permission
, as shown above.
Also, what is the request code?
That will be passed back to you as the first parameter to onRequestPermissionsResult()
, so you can tell one requestPermissions()
call from another.
As of Python 3.5, you can merge two dicts with:
merged = {**dictA, **dictB}
(https://www.python.org/dev/peps/pep-0448/)
So:
jsonMerged = {**json.loads(jsonStringA), **json.loads(jsonStringB)}
asString = json.dumps(jsonMerged)
etc.
The solution below does only one groupBy and extract the rows of your dataframe that contain the maxValue in one shot. No need for further Joins, or Windows.
import org.apache.spark.sql.Row
import org.apache.spark.sql.catalyst.encoders.RowEncoder
import org.apache.spark.sql.DataFrame
//df is the dataframe with Day, Category, TotalValue
implicit val dfEnc = RowEncoder(df.schema)
val res: DataFrame = df.groupByKey{(r) => r.getInt(0)}.mapGroups[Row]{(day: Int, rows: Iterator[Row]) => i.maxBy{(r) => r.getDouble(2)}}
or //div[@id='id-74385'][@class='guest clearfix']
My full example is here, but I will provide a summary below.
Layout
Add a .swift and .xib file each with the same name to your project. The .xib file contains your custom view layout (using auto layout constraints preferably).
Make the swift file the xib file's owner.
Add the following code to the .swift file and hook up the outlets and actions from the .xib file.
import UIKit
class ResuableCustomView: UIView {
let nibName = "ReusableCustomView"
var contentView: UIView?
@IBOutlet weak var label: UILabel!
@IBAction func buttonTap(_ sender: UIButton) {
label.text = "Hi"
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
guard let view = loadViewFromNib() else { return }
view.frame = self.bounds
self.addSubview(view)
contentView = view
}
func loadViewFromNib() -> UIView? {
let bundle = Bundle(for: type(of: self))
let nib = UINib(nibName: nibName, bundle: bundle)
return nib.instantiate(withOwner: self, options: nil).first as? UIView
}
}
Use it
Use your custom view anywhere in your storyboard. Just add a UIView
and set the class name to your custom class name.
For a while Christopher Swasey's approach was the best approach I had found. I asked a couple of the senior devs on my team about it and one of them had the perfect solution! It satisfies every one of the concerns that Christopher Swasey so eloquently addressed and it doesn't require boilerplate subclass code(my main concern with his approach). There is one gotcha, but other than that it is fairly intuitive and easy to implement.
MyCustomClass.swift
MyCustomClass.xib
File's Owner
of the .xib file to be your custom class (MyCustomClass
)class
value (under the identity Inspector
) for your custom view in the .xib file blank. So your custom view will have no specified class, but it will have a specified File's Owner.Assistant Editor
.
Connections Inspector
you will notice that your Referencing Outlets do not reference your custom class (i.e. MyCustomClass
), but rather reference File's Owner
. Since File's Owner
is specified to be your custom class, the outlets will hook up and work propery. NibLoadable
protocol referenced below.
.swift
file name is different from your .xib
file name, then set the nibName
property to be the name of your .xib
file.required init?(coder aDecoder: NSCoder)
and override init(frame: CGRect)
to call setupFromNib()
like the example below.MyCustomClass
).Here is the protocol you will want to reference:
public protocol NibLoadable {
static var nibName: String { get }
}
public extension NibLoadable where Self: UIView {
public static var nibName: String {
return String(describing: Self.self) // defaults to the name of the class implementing this protocol.
}
public static var nib: UINib {
let bundle = Bundle(for: Self.self)
return UINib(nibName: Self.nibName, bundle: bundle)
}
func setupFromNib() {
guard let view = Self.nib.instantiate(withOwner: self, options: nil).first as? UIView else { fatalError("Error loading \(self) from nib") }
addSubview(view)
view.translatesAutoresizingMaskIntoConstraints = false
view.leadingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.leadingAnchor, constant: 0).isActive = true
view.topAnchor.constraint(equalTo: self.safeAreaLayoutGuide.topAnchor, constant: 0).isActive = true
view.trailingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.trailingAnchor, constant: 0).isActive = true
view.bottomAnchor.constraint(equalTo: self.safeAreaLayoutGuide.bottomAnchor, constant: 0).isActive = true
}
}
And here is an example of MyCustomClass
that implements the protocol (with the .xib file being named MyCustomClass.xib
):
@IBDesignable
class MyCustomClass: UIView, NibLoadable {
@IBOutlet weak var myLabel: UILabel!
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
setupFromNib()
}
override init(frame: CGRect) {
super.init(frame: frame)
setupFromNib()
}
}
NOTE: If you miss the Gotcha and set the class
value inside your .xib file to be your custom class, then it will not draw in the storyboard and you will get a EXC_BAD_ACCESS
error when you run the app because it gets stuck in an infinite loop of trying to initialize the class from the nib using the init?(coder aDecoder: NSCoder)
method which then calls Self.nib.instantiate
and calls the init
again.
For completeness:
https://developer.chrome.com/multidevice/android/installtohomescreen
Does Add to homescreen work on Chrome for iOS?
No.
We can use the Comparator.comparing()
method to sort a list based on an object's property.
class SortTest{
public static void main(String[] args) {
ArrayList<ActiveAlarm> activeAlarms = new ArrayList<>(){{
add(new ActiveAlarm("Alarm 1", 5, 10));
add(new ActiveAlarm("Alarm 2", 2, 12));
add(new ActiveAlarm("Alarm 3", 0, 8));
}};
/* I sort the arraylist here using the getter methods */
activeAlarms.sort(Comparator.comparing(ActiveAlarm::getTimeStarted)
.thenComparing(ActiveAlarm::getTimeEnded));
System.out.println(activeAlarms);
}
}
Note that before doing it, you'll have to define at least the getter methods of the properties you want to base your sort on.
public class ActiveAlarm {
public long timeStarted;
public long timeEnded;
private String name = "";
private String description = "";
private String event;
private boolean live = false;
public ActiveAlarm(String name, long timeStarted, long timeEnded) {
this.name = name;
this.timeStarted = timeStarted;
this.timeEnded = timeEnded;
}
public long getTimeStarted() {
return timeStarted;
}
public long getTimeEnded() {
return timeEnded;
}
@Override
public String toString() {
return name;
}
}
Output:
[Alarm 3, Alarm 2, Alarm 1]
If you want to pass data between two actions during a redirect without include any data in the query string, put the model in the TempData object.
ACTION
TempData["datacontainer"] = modelData;
VIEW
var modelData= TempData["datacontainer"] as ModelDataType;
TempData is meant to be a very short-lived instance, and you should only use it during the current and the subsequent requests only! Since TempData works this way, you need to know for sure what the next request will be, and redirecting to another view is the only time you can guarantee this.
Therefore, the only scenario where using TempData will reliably work is when you are redirecting.
The obvious answer to this is "that's what the JLS says."
Thinking about why that is, consider that this behavior can be useful in certain cases. Let's say you want to check a string against a set of other strings, but the number of other strings can vary.
So you have something like this:
for(String s : myStrings) {
check(aString.contains(s));
}
where some s
's are empty strings.
If the empty string is interpreted as "no input," and if your purpose here is ensure that aString
contains all the "inputs" in myStrings
, then it is misleading for the empty string to return false
. All strings contain it because it is nothing. To say they didn't contain it would imply that the empty string had some substance that was not captured in the string, which is false.
The java.io.File
and consorts acts on the local disk file system. The root cause of your problem is that relative paths in java.io
are dependent on the current working directory. I.e. the directory from which the JVM (in your case: the webserver's one) is started. This may for example be C:\Tomcat\bin
or something entirely different, but thus not C:\Tomcat\webapps\contextname
or whatever you'd expect it to be. In a normal Eclipse project, that would be C:\Eclipse\workspace\projectname
. You can learn about the current working directory the following way:
System.out.println(new File(".").getAbsolutePath());
However, the working directory is in no way programmatically controllable. You should really prefer using absolute paths in the File
API instead of relative paths. E.g. C:\full\path\to\file.ext
.
You don't want to hardcode or guess the absolute path in Java (web)applications. That's only portability trouble (i.e. it runs in system X, but not in system Y). The normal practice is to place those kind of resources in the classpath, or to add its full path to the classpath (in an IDE like Eclipse that's the src
folder and the "build path" respectively). This way you can grab them with help of the ClassLoader
by ClassLoader#getResource()
or ClassLoader#getResourceAsStream()
. It is able to locate files relative to the "root" of the classpath, as you by coincidence figured out. In webapplications (or any other application which uses multiple classloaders) it's recommend to use the ClassLoader
as returned by Thread.currentThread().getContextClassLoader()
for this so you can look "outside" the webapp context as well.
Another alternative in webapps is the ServletContext#getResource()
and its counterpart ServletContext#getResourceAsStream()
. It is able to access files located in the public web
folder of the webapp project, including the /WEB-INF
folder. The ServletContext
is available in servlets by the inherited getServletContext()
method, you can call it as-is.
PERMISSIONS: I want to stress the importance of permissions for "sqlplus".
For any "Other" UNIX user other than the Owner/Group to be able to run sqlplus and access an ORACLE database , read/execute permissions are required (rx) for these 4 directories :
$ORACLE_HOME/bin , $ORACLE_HOME/lib, $ORACLE_HOME/oracore, $ORACLE_HOME/sqlplus
Environment. Set those properly:
A. ORACLE_HOME
(example: ORACLE_HOME=/u01/app/oranpgm/product/12.1.0/PRMNRDEV/
)
B. LD_LIBRARY_PATH
(example: ORACLE_HOME=/u01/app/oranpgm/product/12.1.0/PRMNRDEV/lib
)
C. ORACLE_SID
D. PATH
export PATH="$ORACLE_HOME/bin:$PATH"
You can use the std::istream::getline() (or preferably the version that works on std::string) function to get an entire line. Both have versions that allow you to specify the delimiter (end of line character). The default for the string version is '\n'.
chmod +w <directory>
or chmod a+w <directory>
- Write permission for user, group and others
chmod u+w <directory>
- Write permission for user
chmod g+w <directory>
- Write permission for group
chmod o+w <directory>
- Write permission for others
There can be several services with the same class name.
I've just created two apps. The package name of the first app is com.example.mock
. I created a subpackage called lorem
in the app and a service called Mock2Service
. So its fully qualified name is com.example.mock.lorem.Mock2Service
.
Then I created the second app and a service called Mock2Service
. The package name of the second app is com.example.mock.lorem
. The fully qualified name of the service is com.example.mock.lorem.Mock2Service
, too.
Here is my logcat output.
03-27 12:02:19.985: D/TAG(32155): Mock-01: com.example.mock.lorem.Mock2Service
03-27 12:02:33.755: D/TAG(32277): Mock-02: com.example.mock.lorem.Mock2Service
A better idea is to compare ComponentName
instances because equals()
of ComponentName
compares both package names and class names. And there can't be two apps with the same package name installed on a device.
The equals() method of ComponentName
.
@Override
public boolean equals(Object obj) {
try {
if (obj != null) {
ComponentName other = (ComponentName)obj;
// Note: no null checks, because mPackage and mClass can
// never be null.
return mPackage.equals(other.mPackage)
&& mClass.equals(other.mClass);
}
} catch (ClassCastException e) {
}
return false;
}
If your problem is like the following while using Google Chrome:
[XMLHttpRequest cannot load file. Received an invalid response. Origin 'null' is therefore not allowed access.]
Then create a batch file by following these steps:
Open notepad in Desktop.
start "chrome" "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files exit
This will do what? It will open Chrome.exe with file access. Now, from any location in your computer, browse your html files with Google Chrome. I hope this will solve the XMLHttpRequest problem.
Keep in mind : Just use the shortcut bat file to open Chrome when you require it. Tell me if it solves your problem. I had a similar problem and I solved it in this way. Thanks.
If input stream is not closed properly then this exception may happen. make sure : If inputstream used is not used "Before" in some way then where you are intended to read. i.e if read 2nd time from same input stream in single operation then 2nd call will get this exception. Also make sure to close input stream in finally block or something like that.
Android Studio 3
The answers that talk about Maven Central are dated since Android Studio uses JCenter as the default repository center now. Your project's build.gradle file should have something like this:
repositories {
google()
jcenter()
}
So as long as the developer has their Maven repository there (which Picasso does), then all you would have to do is add a single line to the dependencies section of your app's build.gradle file.
dependencies {
// ...
implementation 'com.squareup.picasso:picasso:2.5.2'
}
you can use the like query for comparing the respective string with table vales.
select column name from table_name where column name like 'respective comparing value';
This works for rounding to N digits (if you just want to truncate to N digits remove the Math.round call and use the Math.trunc one):
function roundN(value, digits) {
var tenToN = 10 ** digits;
return /*Math.trunc*/(Math.round(value * tenToN)) / tenToN;
}
Had to resort to such logic at Java in the past when I was authoring data manipulation E-Slate components. That is since I had found out that adding 0.1 many times to 0 you'd end up with some unexpectedly long decimal part (this is due to floating point arithmetics).
A user comment at Format number to always show 2 decimal places calls this technique scaling.
Some mention there are cases that don't round as expected and at http://www.jacklmoore.com/notes/rounding-in-javascript/ this is suggested instead:
function round(value, decimals) {
return Number(Math.round(value+'e'+decimals)+'e-'+decimals);
}
Check a CSS rule that the media query changes. This is guaranteed to always work.
http://www.fourfront.us/blog/jquery-window-width-and-media-queries
HTML:
<body>
...
<div id="mobile-indicator"></div>
</body>
Javascript:
function isMobileWidth() {
return $('#mobile-indicator').is(':visible');
}
CSS:
#mobile-indicator {
display: none;
}
@media (max-width: 767px) {
#mobile-indicator {
display: block;
}
}
Here's a more manual method that works both for Website projects and Web Application projects. (you can't change the project URL from within Visual Studio for Website projects.)
Web Application projects
In Solution Explorer, right-click the project and click Unload Project.
Navigate to the IIS Express ApplicationHost.config file. By default, this file is located in:
%userprofile%\Documents\IISExpress\config
In recent Visual Studio versions and Web Application projects, this file is in the solution folder under [Solution Dir]\.vs\config\applicationhost.config
(note the .vs folder is a hidden item)
Open the ApplicationHost.config file in a text editor. In the <sites>
section, search for your site's name. In the <bindings>
section of your site, you will see an element like this:
<binding protocol="http" bindingInformation="*:56422:localhost" />
Change the port number (56422 in the above example) to anything you want. e.g.:
<binding protocol="http" bindingInformation="*:44444:localhost" />
Bonus: You can even bind to a different host name and do cool things like:
<binding protocol="http" bindingInformation="*:80:mysite.dev" />
and then map mysite.dev
to 127.0.0.1
in your hosts
file, and then open your website from "http://mysite.dev"
In Solution Explorer, right-click the the project and click Reload Project.
In Solution Explorer, right-click the the project and select Properties.
Select the Web tab.
In the Servers section, under Use Local IIS Web server, in the Project URL box enter a URL to match the hostname and port you entered in the ApplicationHost.config file from before.
To the right of the Project URL box, click Create Virtual Directory. If you see a success message, then you've done the steps correctly.
In the File menu, click Save Selected Items.
Website projects
In Solution Explorer, right-click the project name and then click Remove or Delete; don't worry, this removes the project from your solution, but does not delete the corresponding files on disk.
Follow step 2 from above for Web Application projects.
In Solution Explorer, right-click the solution, select Add, and then select Existing Web Site.... In the Add Existing Web Site dialog box, make sure that the Local IIS tab is selected. Under IIS Express Sites, select the site for which you have changed the port number, then click OK.
Now you can access your website from your new hostname/port.
There were some mistakes in harun's answer which are corrected below:
1) date where harun used getDay()
which is incorrect should be getDate()
2) getMonth()
gives one less month than actual month, So we should increment it by 1 as shown below
var date = new Date();
var day = date.getDate(); // yields
var month = date.getMonth() + 1; // yields month
var year = date.getFullYear(); // yields year
var hour = date.getHours(); // yields hours
var minute = date.getMinutes(); // yields minutes
var second = date.getSeconds(); // yields seconds
// After this construct a string with the above results as below
var time = day + "/" + month + "/" + year + " " + hour + ':' + minute + ':' + second;
Pass this string to codebehind function and accept it as a string parameter.Use the DateTime.ParseExact()
in codebehind to convert this string to DateTime
as follows,
DateTime.ParseExact(YourString, "dd/MM/yyyy HH:mm:ss", CultureInfo.InvariantCulture);
This Worked for me! Hope this help you too.
Avoid hardcoding try making the code that is dynamic below is the code it will work for any xml I have used SAX Parser you can use dom,xpath it's upto you
I am storing all the tags name and values in the map after that it becomes easy to retrieve any values you want I hope this helps
SAMPLE XML:
<parent>
<child >
<child1> value 1 </child1>
<child2> value 2 </child2>
<child3> value 3 </child3>
</child>
<child >
<child4> value 4 </child4>
<child5> value 5</child5>
<child6> value 6 </child6>

That's a known issue. Currently you have to use a workaround like shown in your question.
This is working as intended. When the change event is emitted ngModelChange
(the (...)
part of [(ngModel)]
hasn't updated the bound model yet:
<input type="checkbox" (ngModelChange)="myModel=$event" [ngModel]="mymodel">

You can use System Color (18.2) values, introduced with CSS 2.0, but deprecated in CSS 3.
a:link, a:hover, a:active { color: WindowText; }
That way your anchor links will have the same color as normal document text on this system.
If you're using Laravel, my problem was in the name of my Route. Instead:
Route::put('/reason/update', 'REASONController@update');
I wrote:
Route::put('/reason/update', 'RESONController@update');
and when I fixed the controller name, the code worked!
There's little-no documentation on angular for uploading files. A lot of solutions require custom directives other dependencies (jquery in primis... just to upload a file...). After many tries I've found this with just angularjs (tested on v.1.0.6)
html
<input type="file" name="file" onchange="angular.element(this).scope().uploadFile(this.files)"/>
Angularjs (1.0.6) not support ng-model on "input-file" tags so you have to do it in a "native-way" that pass the all (eventually) selected files from the user.
controller
$scope.uploadFile = function(files) {
var fd = new FormData();
//Take the first selected file
fd.append("file", files[0]);
$http.post(uploadUrl, fd, {
withCredentials: true,
headers: {'Content-Type': undefined },
transformRequest: angular.identity
}).success( ...all right!... ).error( ..damn!... );
};
The cool part is the undefined content-type and the transformRequest: angular.identity that give at the $http the ability to choose the right "content-type" and manage the boundary needed when handling multipart data.
the only way to do this is to replace document.write
with your own function which will append elements to the bottom of your page. It is pretty straight forward with jQuery:
document.write = function(htmlToWrite) {
$(htmlToWrite).appendTo('body');
}
If you have html coming to document.write in chunks like the question example you'll need to buffer the htmlToWrite
segments. Maybe something like this:
document.write = (function() {
var buffer = "";
var timer;
return function(htmlPieceToWrite) {
buffer += htmlPieceToWrite;
clearTimeout(timer);
timer = setTimeout(function() {
$(buffer).appendTo('body');
buffer = "";
}, 0)
}
})()
Using Chrome 15.0.865.0 dev. There's an "Event Listeners" section on the Elements panel:
And an "Event Listeners Breakpoints" on the Scripts panel. Use a Mouse -> click breakpoint and then "step into next function call" while keeping an eye on the call stack to see what userland function handles the event. Ideally, you'd replace the minified version of jQuery with an unminified one so that you don't have to step in all the time, and use step over when possible.
First checks if element exists in the array
$.inArray(id, releaseArray) > -1
above line returns the index of that element if it exists in the array, otherwise it returns -1
releaseArray.splice($.inArray(id, releaseArray), 1);
now above line will remove this element from the array if found. To sum up the logic below is the required code to check and remove the element from array.
if ($.inArray(id, releaseArray) > -1) {
releaseArray.splice($.inArray(id, releaseArray), 1);
}
else {
releaseArray.push(id);
}
The following uses regular expressions and searches only on the query string portion of the URL.
Most importantly, this method supports normal and array parameters as in
http://localhost/?fiz=zip&foo[]=!!=&bar=7890#hashhashhash
function getQueryParam(param) {
var result = window.location.search.match(
new RegExp("(\\?|&)" + param + "(\\[\\])?=([^&]*)")
);
return result ? result[3] : false;
}
console.log(getQueryParam("fiz"));
console.log(getQueryParam("foo"));
console.log(getQueryParam("bar"));
console.log(getQueryParam("zxcv"));
Output:
zip
!!=
7890
false
Here's a bash function that makes it easy to view the logs on a remote. It takes two optional arguments. The first one is the branch, it defaults to master. The second one is the remote, it defaults to staging.
git_log_remote() {
branch=${1:-master}
remote=${2:-staging}
git fetch $remote
git checkout $remote/$branch
git log
git checkout -
}
examples:
$ git_log_remote
$ git_log_remote development origin
Try to look at the following link: Python | change text color in shell
Or read here: http://bytes.com/topic/python/answers/21877-coloring-print-lines
In general solution is to use ANSI codes while printing your string.
There is a solution that performs exactly what you need.
As mentioned originally in this answer by SoBeRich, and in my own answer, as of git 2.4.x
git push --atomic origin <branch name> <tag>
(Note: this actually work with HTTPS only with Git 2.24)
As of git 2.4.1, you can do
git config --global push.followTags true
If set to true enable --follow-tags option by default.
You may override this configuration at time of push by specifying --no-follow-tags.
As noted in this thread by Matt Rogers answering Wes Hurd:
--follow-tags
only pushes annotated tags.
git tag -a -m "I'm an annotation" <tagname>
That would be pushed (as opposed to git tag <tagname>
, a lightweight tag, which would not be pushed, as I mentioned here)
Since git 1.8.3 (April 22d, 2013), you no longer have to do 2 commands to push branches, and then to push tags:
The new "
--follow-tags
" option tells "git push
" to push relevant annotated tags when pushing branches out.
You can now try, when pushing new commits:
git push --follow-tags
That won't push all the local tags though, only the one referenced by commits which are pushed with the git push
.
Git 2.4.1+ (Q2 2015) will introduce the option push.followTags
: see "How to make “git push
” include tags within a branch?".
The nuclear option would be git push --mirror
, which will push all refs under refs/
.
You can also push just one tag with your current branch commit:
git push origin : v1.0.0
You can combine the --tags
option with a refspec like:
git push origin --tags :
(since --tags
means: All refs under refs/tags
are pushed, in addition to refspecs explicitly listed on the command line)
You also have this entry "Pushing branches and tags with a single "git push" invocation"
A handy tip was just posted to the Git mailing list by Zoltán Füzesi:
I use
.git/config
to solve this:
[remote "origin"]
url = ...
fetch = +refs/heads/*:refs/remotes/origin/*
push = +refs/heads/*
push = +refs/tags/*
With these lines added
git push origin
will upload all your branches and tags. If you want to upload only some of them, you can enumerate them.
Haven't tried it myself yet, but it looks like it might be useful until some other way of pushing branches and tags at the same time is added to git push.
On the other hand, I don't mind typing:
$ git push && git push --tags
Beware, as commented by Aseem Kishore
push = +refs/heads/*
will force-pushes all your branches.
This bit me just now, so FYI.
René Scheibe adds this interesting comment:
The
--follow-tags
parameter is misleading as only tags under.git/refs/tags
are considered.
Ifgit gc
is run, tags are moved from.git/refs/tags
to.git/packed-refs
. Afterwardsgit push --follow-tags ...
does not work as expected anymore.
I'm not an expert on MySQL I would suggest you look at REGEXP
.
SELECT * FROM MyTable WHERE ColumnX REGEXP '^[a-z]';
You can use the command time /t
for the time and date /t
for the date, here is an example:
@echo off
time /t >%tmp%\time.tmp
date /t >%tmp%\date.tmp
set ttime=<%tmp%\time.tmp
set tdate=<%tmp%\date.tmp
del /f /q %tmp%\time.tmp
del /f /q %tmp%\date.tmp
echo Time: %ttime%
echo Date: %tdate%
pause >nul
You can also use the built in variables %time% and %date%, here is another example:
@echo off
echo Time: %time:~0,5%
echo Date: %date%
pause >nul
you can use triggers. works very well
CREATE TABLE MyTable(
ID INTEGER PRIMARY KEY,
Name TEXT,
Other STUFF,
Timestamp DATETIME);
CREATE TRIGGER insert_Timestamp_Trigger
AFTER INSERT ON MyTable
BEGIN
UPDATE MyTable SET Timestamp =STRFTIME('%Y-%m-%d %H:%M:%f', 'NOW') WHERE id = NEW.id;
END;
CREATE TRIGGER update_Timestamp_Trigger
AFTER UPDATE On MyTable
BEGIN
UPDATE MyTable SET Timestamp = STRFTIME('%Y-%m-%d %H:%M:%f', 'NOW') WHERE id = NEW.id;
END;
string startTime = "7:00 AM";
string endTime = "2:00 PM";
TimeSpan duration = DateTime.Parse(endTime).Subtract(DateTime.Parse(startTime));
Console.WriteLine(duration);
Console.ReadKey();
Will output: 07:00:00.
It also works if the user input military time:
string startTime = "7:00";
string endTime = "14:00";
TimeSpan duration = DateTime.Parse(endTime).Subtract(DateTime.Parse(startTime));
Console.WriteLine(duration);
Console.ReadKey();
Outputs: 07:00:00.
To change the format: duration.ToString(@"hh\:mm")

Addendum:
Over the years it has somewhat bothered me that this is the most popular answer I have ever given; the original answer never actually explained why the OP's code didn't work despite the fact that it is perfectly valid. The only reason it gets so many votes is because the post comes up on Google when people search for a combination of the terms "C#", "timespan", and "between".
To install an APK on your mobile, you can either:
adb install filename.apk
.
Note, you'll need to enable USB debugging for this to work.Note, that you'll have to enable installing packages from Unknown Sources in your Applications settings.
As for getting USB to work, I suggest consulting the Android StackExchange for advice.
There are a couple of Expression Language implementations out there that does this for you, could be preferable to using your own implementation as or if your requirments grow, see for example JUEL and MVEL
I like and have successfully used MVEL in at least one project.

The idea behind StandardScaler
is that it will transform your data such that its distribution will have a mean value 0 and standard deviation of 1.
In case of multivariate data, this is done feature-wise (in other words independently for each column of the data).
Given the distribution of the data, each value in the dataset will have the mean value subtracted, and then divided by the standard deviation of the whole dataset (or feature in the multivariate case).
This error is most often encountered when attempting to reference an array value with a quoted key for interpolation inside a double-quoted string when the entire complex variable construct is not enclosed in {}
.
This will result in Unexpected T_ENCAPSED_AND_WHITESPACE
:
echo "This is a double-quoted string with a quoted array key in $array['key']";
//---------------------------------------------------------------------^^^^^
In a double-quoted string, PHP will permit array key strings to be used unquoted, and will not issue an E_NOTICE
. So the above could be written as:
echo "This is a double-quoted string with an un-quoted array key in $array[key]";
//------------------------------------------------------------------------^^^^^
The entire complex array variable and key(s) can be enclosed in {}
, in which case they should be quoted to avoid an E_NOTICE
. The PHP documentation recommends this syntax for complex variables.
echo "This is a double-quoted string with a quoted array key in {$array['key']}";
//--------------------------------------------------------------^^^^^^^^^^^^^^^
// Or a complex array property of an object:
echo "This is a a double-quoted string with a complex {$object->property->array['key']}";
Of course, the alternative to any of the above is to concatenate the array variable in instead of interpolating it:
echo "This is a double-quoted string with an array variable". $array['key'] . " concatenated inside.";
//----------------------------------------------------------^^^^^^^^^^^^^^^^^^^^^
For reference, see the section on Variable Parsing in the PHP Strings manual page
Using @angular/forms
when you use a <form>
tag it automatically creates a FormGroup
.
For every contained ngModel
tagged <input>
it will create a FormControl
and add it into the FormGroup
created above; this FormControl
will be named into the FormGroup
using attribute name
.
Example:
<form #f="ngForm">
<input type="text" [(ngModel)]="firstFieldVariable" name="firstField">
<span>{{ f.controls['firstField']?.value }}</span>
</form>
Said this, the answer to your question follows.
When you mark it as standalone: true
this will not happen (it will not be added to the FormGroup
).

A simple alternative is to use the new sessionStorage object. Per the comments, if you have 'continue where I left off' checked, sessionStorage will persist between restarts.
From RFC 2616, section 4.3, "Message Body":
A server SHOULD read and forward a message-body on any request; if the request method does not include defined semantics for an entity-body, then the message-body SHOULD be ignored when handling the request.
That is, servers should always read any provided request body from the network (check Content-Length or read a chunked body, etc). Also, proxies should forward any such request body they receive. Then, if the RFC defines semantics for the body for the given method, the server can actually use the request body in generating a response. However, if the RFC does not define semantics for the body, then the server should ignore it.
This is in line with the quote from Fielding above.
Section 9.3, "GET", describes the semantics of the GET method, and doesn't mention request bodies. Therefore, a server should ignore any request body it receives on a GET request.
Because these days ASP.NET is open source, you can find it on GitHub: AspNet.Identity 3.0 and AspNet.Identity 2.0.

You should not be updating 10k rows in a set unless you are certain that the operation is getting Page Locks (due to multiple rows per page being part of the UPDATE
operation). The issue is that Lock Escalation (from either Row or Page to Table locks) occurs at 5000 locks. So it is safest to keep it just below 5000, just in case the operation is using Row Locks.
You should not be using SET ROWCOUNT to limit the number of rows that will be modified. There are two issues here:
It has that been deprecated since SQL Server 2005 was released (11 years ago):
Using SET ROWCOUNT will not affect DELETE, INSERT, and UPDATE statements in a future release of SQL Server. Avoid using SET ROWCOUNT with DELETE, INSERT, and UPDATE statements in new development work, and plan to modify applications that currently use it. For a similar behavior, use the TOP syntax
It can affect more than just the statement you are dealing with:
Setting the SET ROWCOUNT option causes most Transact-SQL statements to stop processing when they have been affected by the specified number of rows. This includes triggers. The ROWCOUNT option does not affect dynamic cursors, but it does limit the rowset of keyset and insensitive cursors. This option should be used with caution.
Instead, use the TOP () clause.
There is no purpose in having an explicit transaction here. It complicates the code and you have no handling for a ROLLBACK, which isn't even needed since each statement is its own transaction (i.e. auto-commit).
Assuming you find a reason to keep the explicit transaction, then you do not have a TRY / CATCH structure. Please see my answer on DBA.StackExchange for a TRY / CATCH template that handles transactions:
Are we required to handle Transaction in C# Code as well as in Store procedure
I suspect that the real WHERE clause is not being shown in the example code in the Question, so simply relying upon what has been shown, a better model would be:
DECLARE @Rows INT,
@BatchSize INT; -- keep below 5000 to be safe
SET @BatchSize = 2000;
SET @Rows = @BatchSize; -- initialize just to enter the loop
BEGIN TRY
WHILE (@Rows = @BatchSize)
BEGIN
UPDATE TOP (@BatchSize) tab
SET tab.Value = 'abc1'
FROM TableName tab
WHERE tab.Parameter1 = 'abc'
AND tab.Parameter2 = 123
AND tab.Value <> 'abc1' COLLATE Latin1_General_100_BIN2;
-- Use a binary Collation (ending in _BIN2, not _BIN) to make sure
-- that you don't skip differences that compare the same due to
-- insensitivity of case, accent, etc, or linguistic equivalence.
SET @Rows = @@ROWCOUNT;
END;
END TRY
BEGIN CATCH
RAISERROR(stuff);
RETURN;
END CATCH;
By testing @Rows
against @BatchSize
, you can avoid that final UPDATE query (in most cases) because the final set is typically some number of rows less than @BatchSize
, in which case we know that there are no more to process (which is what you see in the output shown in your answer). Only in those cases where the final set of rows is equal to @BatchSize
will this code run a final UPDATE affecting 0 rows.
I also added a condition to the WHERE
clause to prevent rows that have already been updated from being updated again.
function person(name, age){
var name = name;
var age = age;
function introduce(){
alert("My name is "+name+", and I'm "+age);
}
return introduce;
}
var a = person("Jack",12);
var b = person("Matt",14);
Everytime the function person
is called a new closure is created. While variables a
and b
have the same introduce
function, it is linked to different closures. And that closure will still exist even after the function person
finishes execution.
a(); //My name is Jack, and I'm 12
b(); //My name is Matt, and I'm 14
An abstract closures could be represented to something like this:
closure a = {
name: "Jack",
age: 12,
call: function introduce(){
alert("My name is "+name+", and I'm "+age);
}
}
closure b = {
name: "Matt",
age: 14,
call: function introduce(){
alert("My name is "+name+", and I'm "+age);
}
}
Assuming you know how a class
in another language work, I will make an analogy.
Think like
function
as a constructor
local variables
as instance properties
properties
are privateinner functions
as instance methods
Everytime a function
is called
object
containing all local variables will be created."properties"
of that instance object.I think you should use the Rails debug options:
logger.debug "Person attributes hash: #{@person.attributes.inspect}"
logger.info "Processing the request..."
logger.fatal "Terminating application, raised unrecoverable error!!!"

I recently had to do this to create half decent looking emails for an email client that did not support the CSS necessary. For an HTML only solution I use a wrapping table to provide the padding.
<table border="1" cellspacing="0" cellpadding="0">_x000D_
<tr><td height="5" colspan="3"></td></tr>_x000D_
<tr>_x000D_
<td width="5"></td>_x000D_
<td>_x000D_
This cells padding matches what you want._x000D_
<ul>_x000D_
<li>5px Left, Top, Bottom padding</li>_x000D_
<li>10px on the right</li>_x000D_
</ul> _x000D_
You can then put your table inside this_x000D_
cell with no spacing or padding set. _x000D_
</td>_x000D_
<td width="10"></td>_x000D_
</tr>_x000D_
<tr><td height="5" colspan="3"></td></tr>_x000D_
</table>
_x000D_
As of 2017 you would only do this for old email client support, it's pretty overkill.
In your regex you need to escape the dot "\."
or use it inside a character class "[.]"
, as it is a meta-character in regex, which matches any character.
Also, you need \w+
instead of \w
to match one or more word characters.
Now, if you want the test.this
content, then split
is not what you need. split
will split your string around the test.this
. For example:
>>> re.split(r"\b\w+\.\w+@", s)
['blah blah blah ', 'gmail.com blah blah']
You can use re.findall
:
>>> re.findall(r'\w+[.]\w+(?=@)', s) # look ahead
['test.this']
>>> re.findall(r'(\w+[.]\w+)@', s) # capture group
['test.this']
List<Tuple<string, DateTime, string>> mylist = new List<Tuple<string, DateTime,string>>();

{
Console.WriteLine(mylist[i]);
}
You can use the DefaultView.ToTable method of a DataTable to do the filtering like this (adapt to C#):
Public Sub RemoveDuplicateRows(ByRef rDataTable As DataTable)
Dim pNewDataTable As DataTable
Dim pCurrentRowCopy As DataRow
Dim pColumnList As New List(Of String)
Dim pColumn As DataColumn
'Build column list
For Each pColumn In rDataTable.Columns
pColumnList.Add(pColumn.ColumnName)
Next
'Filter by all columns
pNewDataTable = rDataTable.DefaultView.ToTable(True, pColumnList.ToArray)
rDataTable = rDataTable.Clone
'Import rows into original table structure
For Each pCurrentRowCopy In pNewDataTable.Rows
rDataTable.ImportRow(pCurrentRowCopy)
Next
End Sub
Have you tried:
eval $cmd
For the follow-on question of how to escape *
since it has special meaning when it's naked or in double quoted strings: use single quotes.
MYSQL='mysql AMORE -u username -ppassword -h localhost -e'
QUERY="SELECT "'*'" FROM amoreconfig" ;# <-- "double"'single'"double"
eval $MYSQL "'$QUERY'"
Bonus: It also reads nice: eval mysql query ;-)
I don't think there are any machine code decompilers that produce Pascal code. Most "Delphi decompilers" parse form and RTTI data, but do not actually decompile the machine code. I can only recommend using something like DeDe (or similar software) to extract symbol information in combination with a C decompiler, then translate the decompiled C code to Delphi (there are many source code converters out there).
Flexbox is a perfect fit for this type of problem. While mostly known for laying out content in the horizontal direction, Flexbox actually works just as well for vertical layout problems. All you have to do is wrap the vertical sections in a flex container and choose which ones you want to expand. They’ll automatically take up all the available space in their container.
Loading the values in an array would be much faster:
Dim data(), dict As Object, r As Long
Set dict = CreateObject("Scripting.Dictionary")
data = ActiveSheet.UsedRange.Columns(1).Value
For r = 1 To UBound(data)
dict(data(r, some_column_number)) = Empty
Next
data = WorksheetFunction.Transpose(dict.keys())
You should also consider early binding for the Scripting.Dictionary:
Dim dict As New Scripting.Dictionary ' requires `Microsoft Scripting Runtime` '
Note that using a dictionary is way faster than Range.AdvancedFilter on large data sets.
As a bonus, here's a procedure similare to Range.RemoveDuplicates to remove duplicates from a 2D array:
Public Sub RemoveDuplicates(data, ParamArray columns())
Dim ret(), indexes(), ids(), r As Long, c As Long
Dim dict As New Scripting.Dictionary ' requires `Microsoft Scripting Runtime` '
If VarType(data) And vbArray Then Else Err.Raise 5, , "Argument data is not an array"
ReDim ids(LBound(columns) To UBound(columns))
For r = LBound(data) To UBound(data) ' each row '
For c = LBound(columns) To UBound(columns) ' each column '
ids(c) = data(r, columns(c)) ' build id for the row
Next
dict(Join$(ids, ChrW(-1))) = r ' associate the row index to the id '
Next
indexes = dict.Items()
ReDim ret(LBound(data) To LBound(data) + dict.Count - 1, LBound(data, 2) To UBound(data, 2))
For c = LBound(ret, 2) To UBound(ret, 2) ' each column '
For r = LBound(ret) To UBound(ret) ' each row / unique id '
ret(r, c) = data(indexes(r - 1), c) ' copy the value at index '
Next
Next
data = ret
End Sub

.parse(date); // use parse(date, LocalDateTime::from) to get LocalDateTime

What I was trying to achieve was using already provided private key and certificate to sign message that was going someplace that needed to make sure that the message was coming from me (private keys sign while public keys encrypt).
So if you already have a .key file and a .crt file?
Try this:
Step1: Convert the key and cert to .p12 file
openssl pkcs12 -export -in certificate.crt -inkey privateKey.key -name alias -out yourconvertedfile.p12
Step 2: Import the key and create a .jsk file with a single command
keytool -importkeystore -deststorepass changeit -destkeystore keystore.jks -srckeystore umeme.p12 -srcstoretype PKCS12
Step 3: In your java:
char[] keyPassword = "changeit".toCharArray();
KeyStore keyStore = KeyStore.getInstance("JKS");
InputStream keyStoreData = new FileInputStream("keystore.jks");
keyStore.load(keyStoreData, keyPassword);
KeyStore.ProtectionParameter entryPassword = new KeyStore.PasswordProtection(keyPassword);
KeyStore.PrivateKeyEntry privateKeyEntry = (KeyStore.PrivateKeyEntry)keyStore.getEntry("alias", entryPassword);
System.out.println(privateKeyEntry.toString());
If you need to sign some string using this key do the following:
Step 1: Convert the text you want to encrypt
byte[] data = "test".getBytes("UTF8");
Step 2: Get base64 encoded private key
keyStore.load(keyStoreData, keyPassword);
//get cert, pubkey and private key from the store by alias
Certificate cert = keyStore.getCertificate("localhost");
PublicKey publicKey = cert.getPublicKey();
KeyPair keyPair = new KeyPair(publicKey, (PrivateKey) key);
//sign with this alg
Signature sig = Signature.getInstance("SHA1WithRSA");
sig.initSign(keyPair.getPrivate());
sig.update(data);

In nodeJS you can you use the "this" special keyword within the setInterval function.
You can use this this keyword to clearInterval, and here is an example:
setInterval(
function clear() {
clearInterval(this)
return clear;
}()
, 1000)
When you print the value of this special keyword within the function you outpout a Timeout object Timeout {...}
please try with setting margin and padding to 0 on body.
<body style="margin: 0 0 0 0; padding: 0 0 0 0;">
I ran across this error on a Beaglebone Black using the standard Angstrom distribution. It is currently running Python 2.7.3, but does not include distutils. The solution for me was to install distutils. (It required su privileges.)
su
opkg install python-distutils
After that installation, the previously erroring command ran fine.
python setup.py build
When you have everything #included, an unresolved external symbol is often a missing * or & in the declaration or definition of a function.
select id,count,sum(count)over(order by count desc) as cumulative_sum from tableName;
I have used the sum aggregate function on the count column and then used the over clause. It sums up each one of the rows individually. The first row is just going to be 100. The second row is going to be 100+50. The third row is 100+50+10 and so forth. So basically every row is the sum of it and all the previous rows and the very last one is the sum of all the rows. So the way to look at this is each row is the sum of the amount where the ID is less than or equal to itself.
Yes, it's intended to be checked in. I want to suggest that it gets its own unique commit. We find that it adds a lot of noise to our diffs.
Put your style.css
directly into the webapp/css
folder, not into the WEB-INF
folder.
Then add the following code into your spring-dispatcher-servlet.xml
<mvc:resources mapping="/css/**" location="/css/" />
and then add following code into your jsp page
<link rel="stylesheet" type="text/css" href="css/style.css"/>
I hope it will work.
Have a look at the advanced wheres documentation for Fluent: http://laravel.com/docs/queries#advanced-wheres
Here's an example of what you're trying to achieve:
DB::table('users')
->whereIn('id', function($query)
{
$query->select(DB::raw(1))
->from('orders')
->whereRaw('orders.user_id = users.id');
})
->get();
This will produce:
select * from users where id in (
select 1 from orders where orders.user_id = users.id
)
It may seem as being too cautious, but I frequently zip a copy of whatever I've been working on before I make source control changes. In a Gitlab project I'm working on, I recently deleted a remote branch by mistake that I wanted to keep after merging a merge request. It turns out all I had to do to get it back with the commit history was push again. The merge request was still tracked by Gitlab, so it still shows the blue 'merged' label to the right of the branch. I still zipped my local folder in case something bad happened.
I am trying to get int x equal to 5 (as seen in the setNum() method) but when it prints it gives me 0.
To run the code in setNum
you have to call it. If you don't call it, the default value is 0
.
I made a function version of Oscar's answer, this one also copies the environment and changes to the appropriate directory
function new_window {
TMP_FILE=$(mktemp "/tmp/command.XXXXXX")
echo "#!/usr/bin/env bash" > $TMP_FILE
# Copy over environment (including functions), but filter out readonly stuff
set | grep -v "\(BASH_VERSINFO\|EUID\|PPID\|SHELLOPTS\|UID\)" >> $TMP_FILE
# Copy over exported envrionment
export -p >> $TMP_FILE
# Change to directory
echo "cd $(pwd)" >> $TMP_FILE
# Copy over target command line
echo "$@" >> $TMP_FILE
chmod +x "$TMP_FILE"
open -b com.apple.terminal "$TMP_FILE"
sleep .1 # Wait for terminal to start
rm "$TMP_FILE"
}
You can use it like this:
new_window my command here
or
new_window ssh example.com
IMHO, most arguments against recursive locks (which are what I use 99.9% of the time over like 20 years of concurrent programming) mix the question if they are good or bad with other software design issues, which are quite unrelated. To name one, the "callback" problem, which is elaborated on exhaustively and without any multithreading related point of view, for example in the book Component software - beyond Object oriented programming.
As soon as you have some inversion of control (e.g. events fired), you face re-entrance problems. Independent of whether there are mutexes and threading involved or not.
class EvilFoo {
std::vector<std::string> data;
std::vector<std::function<void(EvilFoo&)> > changedEventHandlers;
public:
size_t registerChangedHandler( std::function<void(EvilFoo&)> handler) { // ...
}
void unregisterChangedHandler(size_t handlerId) { // ...
}
void fireChangedEvent() {
// bad bad, even evil idea!
for( auto& handler : changedEventHandlers ) {
handler(*this);
}
}
void AddItem(const std::string& item) {
data.push_back(item);
fireChangedEvent();
}
};
Now, with code like the above you get all error cases, which would usually be named in the context of recursive locks - only without any of them. An event handler can unregister itself once it has been called, which would lead to a bug in a naively written fireChangedEvent()
. Or it could call other member functions of EvilFoo
which cause all sorts of problems. The root cause is re-entrance.
Worst of all, this could not even be very obvious as it could be over a whole chain of events firing events and eventually we are back at our EvilFoo (non- local).
So, re-entrance is the root problem, not the recursive lock. Now, if you felt more on the safe side using a non-recursive lock, how would such a bug manifest itself? In a deadlock whenever unexpected re-entrance occurs. And with a recursive lock? The same way, it would manifest itself in code without any locks.
So the evil part of EvilFoo
are the events and how they are implemented, not so much a recursive lock. fireChangedEvent()
would need to first create a copy of changedEventHandlers
and use that for iteration, for starters.
Another aspect often coming into the discussion is the definition of what a lock is supposed to do in the first place:
The way I do my concurrent programming, I have a mental model of the latter (protect a resource). This is the main reason why I am good with recursive locks. If some (member) function needs locking of a resource, it locks. If it calls another (member) function while doing what it does and that function also needs locking - it locks. And I don't need an "alternate approach", because the ref-counting of the recursive lock is quite the same as if each function wrote something like:
void EvilFoo::bar() {
auto_lock lock(this); // this->lock_holder = this->lock_if_not_already_locked_by_same_thread())
// do what we gotta do
// ~auto_lock() { if (lock_holder) unlock() }
}
And once events or similar constructs (visitors?!) come into play, I do not hope to get all the ensuing design problems solved by some non-recursive lock.
I had the same problem. I had another program open that was using my laptop's camera. So I closed that program, and then everything worked. I found this answer by checking https://howto.streamlabs.com/streamlabs-obs-9/black-screen-when-using-video-capture-device-elgato-hd-60s-9508.

Microsoft Office 365 (2019) introduced new things called comments and renamed the old comments as "notes". Therefore in the steps above do New Note

Swift 3 & IBInspectable solution:
Inspired by Ade's solution
First, create an UIView extension:
//
// UIView-Extension.swift
//
import Foundation
import UIKit
@IBDesignable
extension UIView {
// Shadow
@IBInspectable var shadow: Bool {
get {
return layer.shadowOpacity > 0.0
}
set {
if newValue == true {
self.addShadow()
}
}
}
fileprivate func addShadow(shadowColor: CGColor = UIColor.black.cgColor, shadowOffset: CGSize = CGSize(width: 3.0, height: 3.0), shadowOpacity: Float = 0.35, shadowRadius: CGFloat = 5.0) {
let layer = self.layer
layer.masksToBounds = false
layer.shadowColor = shadowColor
layer.shadowOffset = shadowOffset
layer.shadowRadius = shadowRadius
layer.shadowOpacity = shadowOpacity
layer.shadowPath = UIBezierPath(roundedRect: layer.bounds, cornerRadius: layer.cornerRadius).cgPath
let backgroundColor = self.backgroundColor?.cgColor
self.backgroundColor = nil
layer.backgroundColor = backgroundColor
}
// Corner radius
@IBInspectable var circle: Bool {
get {
return layer.cornerRadius == self.bounds.width*0.5
}
set {
if newValue == true {
self.cornerRadius = self.bounds.width*0.5
}
}
}
@IBInspectable var cornerRadius: CGFloat {
get {
return self.layer.cornerRadius
}
set {
self.layer.cornerRadius = newValue
}
}
// Borders
// Border width
@IBInspectable
public var borderWidth: CGFloat {
set {
layer.borderWidth = newValue
}
get {
return layer.borderWidth
}
}
// Border color
@IBInspectable
public var borderColor: UIColor? {
set {
layer.borderColor = newValue?.cgColor
}
get {
if let borderColor = layer.borderColor {
return UIColor(cgColor: borderColor)
}
return nil
}
}
}
Then, simply select your UIView in interface builder setting shadow ON and corner radius, like below:
The result!
one more suggestion :
unsigned int a = 0xABCDEF23;
a = ((a&(0x0000FFFF)) << 16) | ((a&(0xFFFF0000)) >> 16);
a = ((a&(0x00FF00FF)) << 8) | ((a&(0xFF00FF00)) >>8);
printf("%0x\n",a);
Get the entire record as you want using the condition with inner select query.

WHERE login_id = [email protected])
What is the source of these values?
The "source" of the coefficients posted are the NTSC specifications which can be seen in Rec601 and Characteristics of Television.
The "ultimate source" are the CIE circa 1931 experiments on human color perception. The spectral response of human vision is not uniform. Experiments led to weighting of tristimulus values based on perception. Our L, M, and S cones1 are sensitive to the light wavelengths we identify as "Red", "Green", and "Blue" (respectively), which is where the tristimulus primary colors are derived.2
The linear light3 spectral weightings for sRGB (and Rec709) are:
These are specific to the sRGB and Rec709 colorspaces, which are intended to represent computer monitors (sRGB) or HDTV monitors (Rec709), and are detailed in the ITU documents for Rec709 and also BT.2380-2 (10/2018)
FOOTNOTES
(1) Cones are the color detecting cells of the eye's retina.
(2) However, the chosen tristimulus wavelengths are NOT at the "peak" of each cone type - instead tristimulus values are chosen such that they stimulate on particular cone type substantially more than another, i.e. separation of stimulus.
(3) You need to linearize your sRGB values before applying the coefficients. I discuss this in another answer here.
I had the same problem,
Just edit the .wixproj to have all of the
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' ... >
elements to be side by side.
That solved my issue
Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin
not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors
at your server side.
You can fetch request using mode: 'cors'
. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.
So in both condition you need to configure cors
in your server or you need to use custom proxy server.
For Windows Subsystem for Linux (WSL) you'll need
apt install libswt-gtk-4-jni
If you don't have an OpenJDK 8 you'll also need
apt install openjdk-8-jdk
I had the same problem and only this solution worked for me (it runs a function after a complete DOM has been loaded). I use this for scroll to anchor after page has been loaded:
angular.element(window.document.body).ready(function () {
// Your function that runs after all DOM is loaded
});
I faced the same problem. Initially I deleted the .bash_profile but this is not the right way. After installing anaconda it is showing the instructions clearly for this problem. Please check the image for solution provided by Anaconda
how about using IN
DELETE FROM tableName
WHERE ID IN (1,2) -- add as many ID as you want.
The name accepted into TR1 (and the draft for the next standard) is std::unordered_map
, so if you have that available, it's probably the one you want to use.
Other than that, using it is a lot like using std::map
, with the proviso that when/if you traverse the items in an std::map
, they come out in the order specified by operator<
, but for an unordered_map, the order is generally meaningless.
You can use DataFrame
constructor with lists
created by to_list
:
import pandas as pd
d1 = {'teams': [['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG'],
['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG']]}
df2 = pd.DataFrame(d1)
print (df2)
teams
0 [SF, NYG]
1 [SF, NYG]
2 [SF, NYG]
3 [SF, NYG]
4 [SF, NYG]
5 [SF, NYG]
6 [SF, NYG]
df2[['team1','team2']] = pd.DataFrame(df2.teams.tolist(), index= df2.index)
print (df2)
teams team1 team2
0 [SF, NYG] SF NYG
1 [SF, NYG] SF NYG
2 [SF, NYG] SF NYG
3 [SF, NYG] SF NYG
4 [SF, NYG] SF NYG
5 [SF, NYG] SF NYG
6 [SF, NYG] SF NYG
And for new DataFrame
:
df3 = pd.DataFrame(df2['teams'].to_list(), columns=['team1','team2'])
print (df3)
team1 team2
0 SF NYG
1 SF NYG
2 SF NYG
3 SF NYG
4 SF NYG
5 SF NYG
6 SF NYG
Solution with apply(pd.Series)
is very slow:
#7k rows
df2 = pd.concat([df2]*1000).reset_index(drop=True)
In [121]: %timeit df2['teams'].apply(pd.Series)
1.79 s ± 52.5 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
In [122]: %timeit pd.DataFrame(df2['teams'].to_list(), columns=['team1','team2'])
1.63 ms ± 54.3 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
Try this, it works!
<div class="row">
<div class="center">
<div class="col-xs-12 col-sm-4">
<p>hi 1!</div>
</div>
<div class="col-xs-12 col-sm-4">
<p>hi 2!</div>
</div>
<div class="col-xs-12 col-sm-4">
<p>hi 3!</div>
</div>
</div>
</div>
Then, in css define the width of center div and center in a document:
.center {
margin: 0 auto;
width: 80%;
}
df <- head(mtcars)
df$string <- c("a","b", "c", "d","e", "f"); df
my.min <- unlist(lapply(df, min))
my.max <- unlist(lapply(df, max))
You can create an alias for it. I am using ZSH shell with Oh-my-Zsh and here is an handy alias:
# delete and re-init git
# usage: just type 'gdelinit' in a local repository
alias gdelinit="trash .git && git init"
I am using Trash to trash the .git
folder since using rm
is really dangerous:
trash .git
Then I am re-initializing the git repo:
git init
Wouldn't that be "
in xml? i.e.
"hi "mom" lol"
**edit: ** tested; works fine:
declare @xml xml
set @xml = '<transaction><item value="hi "mom" lol"
ItemId="106" ItemType="2" instanceId="215923801" dataSetId="1" /></transaction>'
select @xml.value('(//item/@value)[1]','varchar(50)')
If you don't mind reading bytecode, javap should work fine. It's part of the standard JDK installation.
Usage: javap <options> <classes>...
where options include:
-c Disassemble the code
-classpath <pathlist> Specify where to find user class files
-extdirs <dirs> Override location of installed extensions
-help Print this usage message
-J<flag> Pass <flag> directly to the runtime system
-l Print line number and local variable tables
-public Show only public classes and members
-protected Show protected/public classes and members
-package Show package/protected/public classes
and members (default)
-private Show all classes and members
-s Print internal type signatures
-bootclasspath <pathlist> Override location of class files loaded
by the bootstrap class loader
-verbose Print stack size, number of locals and args for methods
If verifying, print reasons for failure
Simple & clean. Only uses System.IO.FileSystem
- works like a charm:
string path = "C:/folder1/folder2/file.txt";
string folder = new DirectoryInfo(path).Name;
With ES6 you can do it very short:
options.filter(opt => !opt.assigned).map(opt => someNewObject)
Javascript is base of jQuery.
jQuery is a wrapper of JavaScript, with much pre-written functionality and DOM traversing.
Update: This supports only with UWP - Windows Community Toolkit
There is a much easier way now. You can use the RssParser class. The sample code is given below.
public async void ParseRSS()
{
string feed = null;
using (var client = new HttpClient())
{
try
{
feed = await client.GetStringAsync("https://visualstudiomagazine.com/rss-feeds/news.aspx");
}
catch { }
}
if (feed != null)
{
var parser = new RssParser();
var rss = parser.Parse(feed);
foreach (var element in rss)
{
Console.WriteLine($"Title: {element.Title}");
Console.WriteLine($"Summary: {element.Summary}");
}
}
}
For non-UWP use the Syndication from the namespace System.ServiceModel.Syndication
as others suggested.
public static IEnumerable <FeedItem> GetLatestFivePosts() {
var reader = XmlReader.Create("https://sibeeshpassion.com/feed/");
var feed = SyndicationFeed.Load(reader);
reader.Close();
return (from itm in feed.Items select new FeedItem {
Title = itm.Title.Text, Link = itm.Id
}).ToList().Take(5);
}
public class FeedItem {
public string Title {
get;
set;
}
public string Link {
get;
set;
}
}
The by far the simplest approach is:
yourdf.drop(['columnheading1', 'columnheading2'], axis=1, inplace=True)
\df+ <function_name>
in psql.
There is a jQuery solution in this thread. Try something like this:
var decoded = $("<div/>").html('your string').text();
This sets the innerHTML of a new <div>
element (not appended to the page), causing jQuery to decode it into HTML, which is then pulled back out with .text()
.
Arguments
property in Execute Process Task available on the Control Flow tab is expecting a value of data type DT_WSTR
and not DT_STR
.
Create an SSIS package in Business Intelligence Development Studio (BIDS) 2008 R2 and name it as SO_13177007.dtsx
. Create a package variable with the following information.
Name Scope Data Type Value
------ ------------ ---------- -----
IdVar SO_13177007 Int32 123
Drag and drop an Execute Process Task onto the Control Flow tab and name it as Pass arguments
Double-click the Execute Process Task to open the Execute Process Task Editor
. Click Expressions page and then click the Ellipsis button against the Expressions property to view the Property Expression Editor
.
On the Property Expression Editor, select the property Arguments
and click the Ellipsis button against the property to open the Expression Builder
.
On the Expression Builder, enter the following expression and click Evaluate Expression
. This expression tries to convert the integer value in the variable IdVar
to string data type.
(DT_STR, 10, 1252) @[User::IdVar]
Clicking Evaluate Expression will display the following error message because the Arguments property on Execute Process Task expects a value of data type DT_WSTR
.
To fix the issue, update the expression as shown below to convert the integer value to data type DT_WSTR
. Clicking Evaluate Expression will display the value in the Evaluated value text area.
(DT_WSTR, 10) @[User::IdVar]
To understand the differences between the data types DT_STR
and DT_WSTR
in SSIS, read the documentation Integration Services Data Types on MSDN. Here are the quotes from the documentation about these two string data types.
A null-terminated ANSI/MBCS character string with a maximum length of 8000 characters. (If a column value contains additional null terminators, the string will be truncated at the occurrence of the first null.)
A null-terminated Unicode character string with a maximum length of 4000 characters. (If a column value contains additional null terminators, the string will be truncated at the occurrence of the first null.)
Try this style instead, it modifies the template itself. In there you can change everything you need to transparent:
<Style TargetType="{x:Type TabItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid>
<Border Name="Border" Margin="0,0,0,0" Background="Transparent"
BorderBrush="Black" BorderThickness="1,1,1,1" CornerRadius="5">
<ContentPresenter x:Name="ContentSite" VerticalAlignment="Center"

RecognizesAccessKey="True">
<ContentPresenter.LayoutTransform>
<RotateTransform Angle="270" />
</ContentPresenter.LayoutTransform>
</ContentPresenter>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Panel.ZIndex" Value="100" />
<Setter TargetName="Border" Property="Background" Value="Red" />
<Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,0" />
</Trigger>
<Trigger Property="IsEnabled" Value="False">

You shouldn't use both ngRoute
and UI-router
. Here's a sample code for UI-router:
repoApp.config(function($stateProvider, $urlRouterProvider) {_x000D_
_x000D_
$stateProvider_x000D_
.state('state1', {_x000D_
url: "/state1",_x000D_
templateUrl: "partials/state1.html",_x000D_
controller: 'YourCtrl'_x000D_
})_x000D_
_x000D_
.state('state2', {_x000D_
url: "/state2",_x000D_
templateUrl: "partials/state2.html",_x000D_
controller: 'YourOtherCtrl'_x000D_
});_x000D_
$urlRouterProvider.otherwise("/state1");_x000D_
});_x000D_
//etc.
_x000D_
You can find a great answer on the difference between these two in this thread: What is the difference between angular-route and angular-ui-router?
You can also consult UI-Router's docs here: https://github.com/angular-ui/ui-router
The full paramiko distribution ships with a lot of good demos.
In the demos subdirectory, demo.py
and interactive.py
have full interactive TTY examples which would probably be overkill for your situation.
In your example above ssh_stdin
acts like a standard Python file object, so ssh_stdin.write
should work so long as the channel is still open.
I've never needed to write to stdin, but the docs suggest that a channel is closed as soon as a command exits, so using the standard stdin.write
method to send a password up probably won't work. There are lower level paramiko commands on the channel itself that give you more control - see how the SSHClient.exec_command
method is implemented for all the gory details.
JSONP is a great away to get around cross-domain scripting errors. You can consume a JSONP service purely with JS without having to implement a AJAX proxy on the server side.
You can use the b1t.co service to see how it works. This is a free JSONP service that alllows you to minify your URLs. Here is the url to use for the service:
http://b1t.co/Site/api/External/MakeUrlWithGet?callback=[resultsCallBack]&url=[escapedUrlToMinify]
For example the call, http://b1t.co/Site/api/External/MakeUrlWithGet?callback=whateverJavascriptName&url=google.com
would return
whateverJavascriptName({"success":true,"url":"http://google.com","shortUrl":"http://b1t.co/54"});
And thus when that get's loaded in your js as a src, it will automatically run whateverJavascriptName which you should implement as your callback function:
function minifyResultsCallBack(data)
{
document.getElementById("results").innerHTML = JSON.stringify(data);
}
To actually make the JSONP call, you can do it about several ways (including using jQuery) but here is a pure JS example:
function minify(urlToMinify)
{
url = escape(urlToMinify);
var s = document.createElement('script');
s.id = 'dynScript';
s.type='text/javascript';
s.src = "http://b1t.co/Site/api/External/MakeUrlWithGet?callback=resultsCallBack&url=" + url;
document.getElementsByTagName('head')[0].appendChild(s);
}
A step by step example and a jsonp web service to practice on is available at: this post
Add a CommandName attribute, and optionally a CommandArgument attribute, to your LinkButton control. Then set the OnCommand attribute to the name of your Command event handler.
<asp:LinkButton ID="ENameLinkBtn" runat="server" CommandName="MyValueGoesHere" CommandArgument="OtherValueHere"
style="font-weight: 700; font-size: 8pt;" OnCommand="ENameLinkBtn_Command" ><%# Eval("EName") %></asp:LinkButton>
<asp:Label id="Label1" runat="server"/>
Then it will be available when in your handler:
protected void ENameLinkBtn_Command (object sender, CommandEventArgs e)
{
Label1.Text = "You chose: " + e.CommandName + " Item " + e.CommandArgument;
}

Using importlib worked the best for me.
import importlib
importlib.import_module('accounting.views')
This uses string dot notation for the python module that you want to import.
openSession
: When you call SessionFactory.openSession
, it always creates a new Session
object and give it to you.
You need to explicitly flush and close these session objects.
As session objects are not thread safe, you need to create one session object per request in multi-threaded environment and one session per request in web applications too.
getCurrentSession
: When you call SessionFactory.getCurrentSession
, it will provide you session object which is in hibernate context and managed by hibernate internally. It is bound to transaction scope.
When you call SessionFactory.getCurrentSession
, it creates a new Session
if it does not exist, otherwise use same session which is in current hibernate context. It automatically flushes and closes session when transaction ends, so you do not need to do it externally.
If you are using hibernate in single-threaded environment , you can use getCurrentSession
, as it is faster in performance as compared to creating a new session each time.
You need to add following property to hibernate.cfg.xml to use getCurrentSession
method:
<session-factory>
<!-- Put other elements here -->
<property name="hibernate.current_session_context_class">
thread
</property>
</session-factory>
The {{variable}}
is substituted directly into the HTML. Do a view source; it isn't a "variable" or anything like it. It's just rendered text.
Having said that, you can put this kind of substitution into your JavaScript.
<script type="text/javascript">
var a = "{{someDjangoVariable}}";
</script>
This gives you "dynamic" javascript.
With Ruby 1.8.7 I encode every field to UTF-16 and discard BOM (maybe).
The following code is extracted from active_scaffold_export:
<%
require 'fastercsv'
fcsv_options = {
:row_sep => "\n",
:col_sep => params[:delimiter],
:force_quotes => @export_config.force_quotes,
:headers => @export_columns.collect { |column| format_export_column_header_name(column) }
}
data = FasterCSV.generate(fcsv_options) do |csv|
csv << fcsv_options[:headers] unless params[:skip_header] == 'true'
@records.each do |record|
csv << @export_columns.collect { |column|
# Convert to UTF-16 discarding the BOM, required for Excel (> 2003 ?)
Iconv.conv('UTF-16', 'UTF-8', get_export_column_value(record, column))[2..-1]
}
end
end
-%><%= data -%>
The important line is:
Iconv.conv('UTF-16', 'UTF-8', get_export_column_value(record, column))[2..-1]
There is solution for you :)
You must run your script after window loaded
if you use jQuery, you can use simple way:
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'your-app-id',
xfbml : true,
status : true,
version : 'v2.5'
});
};
(function(d, s, id){
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) {return;}
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>
<script>
$(window).load(function() {
var comment_callback = function(response) {
console.log("comment_callback");
console.log(response);
}
FB.Event.subscribe('comment.create', comment_callback);
FB.Event.subscribe('comment.remove', comment_callback);
});
</script>
OK, so big Props to Joel Muller for all his input. My ultimate solution was to use the Custom SessionStateModule detailed at the end of this MSDN article:
http://msdn.microsoft.com/en-us/library/system.web.sessionstate.sessionstateutility.aspx
This was:
This has made a HUGE difference to the feeling of "snapiness" to our application. I still can't believe the custom implementation of ASP.Net Session locks the session for the whole request. This adds such a huge amount of sluggishness to websites. Judging from the amount of online research I had to do (and conversations with several really experienced ASP.Net developers), a lot of people have experienced this issue, but very few people have ever got to the bottom of the cause. Maybe I will write a letter to Scott Gu...
I hope this helps a few people out there!
Structs can have functions just like classes. The only difference is that they are public by default:
struct A {
void f() {}
};
Additionally, structs can also have constructors and destructors.
struct A {
A() : x(5) {}
~A() {}
private: int x;
};
I wanted to support apps pre api 23 and instead of using checkSelfPermission
I used a try / catch
try {
location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
} catch (SecurityException e) {
dialogGPS(this.getContext()); // lets the user know there is a problem with the gps
}
Try this:
$(document).on('click','#save',function(e) {
var data = $("#form-search").serialize();
$.ajax({
data: data,
type: "post",
url: "insertmail.php",
success: function(data){
alert("Data Save: " + data);
}
});
});
and in insertmail.php:
<?php
if(isset($_REQUEST))
{
mysql_connect("localhost","root","");
mysql_select_db("eciticket_db");
error_reporting(E_ALL && ~E_NOTICE);
$email=$_POST['email'];
$sql="INSERT INTO newsletter_email(email) VALUES ('$email')";
$result=mysql_query($sql);
if($result){
echo "You have been successfully subscribed.";
}
}
?>
Don't use mysql_
it's deprecated.
another method:
Actually if your problem is null value inserted into the database then try this and here no need of ajax.
<?php
if($_POST['email']!="")
{
mysql_connect("localhost","root","");
mysql_select_db("eciticket_db");
error_reporting(E_ALL && ~E_NOTICE);
$email=$_POST['email'];
$sql="INSERT INTO newsletter_email(email) VALUES ('$email')";
$result=mysql_query($sql);
if($result){
//echo "You have been successfully subscribed.";
setcookie("msg","You have been successfully subscribed.",time()+5,"/");
header("location:yourphppage.php");
}
if(!$sql)
die(mysql_error());
mysql_close();
}
?>
<?php if(isset($_COOKIE['msg'])){?>
<span><?php echo $_COOKIE['msg'];setcookie("msg","",time()-5,"/");?></span>
<?php }?>
<form id="form-search" method="post" action="<?php echo $_SERVER['PHP_SELF'];?>">
<span><span class="style2">Enter you email here</span>:</span>
<input name="email" type="email" id="email" required/>
<input type="submit" value="subscribe" class="submit"/>
</form>
If you press Ctrl + Enter after you press something like "/wordforsearch", then you can find the word "wordforsearch" in the current line. Then press n for the next match; press N for previous match.
The correct HTML to use for images with captions, is <figure>
with <figcaption>
.
There's no Markdown equivalent for this, so if you're only adding the occasional caption, I'd encourage you to just add that html into your Markdown document:
Lorem ipsum dolor sit amet, consectetur adipiscing elit...
<figure>
<img src="{{site.url}}/assets/image.jpg" alt="my alt text"/>
<figcaption>This is my caption text.</figcaption>
</figure>
Vestibulum eu vulputate magna...
The Markdown spec encourages you to embed HTML in cases like this, so it will display just fine. It's also a lot simpler than messing with plugins.
If you're trying to use other Markdown-y features (like tables, asterisks, etc) to produce captions, then you're just hacking around how Markdown was intended to be used.
You should be using datetime.datetime.strptime
. Note that very old versions of Python (2.4 and older) don't have datetime.datetime.strptime
; use time.strptime
in that case.
You can totally avoid disabling, it is painful since html form format won't send anything related to <p>
or some other label.
So you can instead put regular
<input text tag just before you have `/>
add this
readonly="readonly"
It wouldn't disable your text but wouldn't change by user so it work like <p>
and will send value through form. Just remove border if you would like to make it more like <p>
tag
I think it might be preferred to actually do
if isinstance(x, str):
do_something_with_a_string(x)
elif isinstance(x, dict):
do_somethting_with_a_dict(x)
else:
raise ValueError
2 Alternate forms, depending on your code one or the other is probably considered better than that even. One is to not look before you leap
try:
one, two = tupleOrValue
except TypeError:
one = tupleOrValue
two = None
The other approach is from Guido and is a form of function overloading which leaves your code more open ended.
