Can this code be simplified in one if test instead two?
nil
and ''
are different values. If you need to test that s
is neither, IMO you should just compare against both, because it makes your intent the most clear.
That and a few alternatives, with their generated bytecode:
if not foo or foo == '' then end
GETGLOBAL 0 -1 ; foo
TEST 0 0 0
JMP 3 ; to 7
GETGLOBAL 0 -1 ; foo
EQ 0 0 -2 ; - ""
JMP 0 ; to 7
if foo == nil or foo == '' then end
GETGLOBAL 0 -1 ; foo
EQ 1 0 -2 ; - nil
JMP 3 ; to 7
GETGLOBAL 0 -1 ; foo
EQ 0 0 -3 ; - ""
JMP 0 ; to 7
if (foo or '') == '' then end
GETGLOBAL 0 -1 ; foo
TEST 0 0 1
JMP 1 ; to 5
LOADK 0 -2 ; ""
EQ 0 0 -2 ; - ""
JMP 0 ; to 7
The second is fastest in Lua 5.1 and 5.2 (on my machine anyway), but difference is tiny. I'd go with the first for clarity's sake.
For those wondering why ipairs doesn't print all the values of the table all the time, here's why (I would comment this, but I don't have enough good boy points).
The function ipairs only works on tables which have an element with the key 1. If there is an element with the key 1, ipairs will try to go as far as it can in a sequential order, 1 -> 2 -> 3 -> 4 etc until it cant find an element with a key that is the next in the sequence. The order of the elements does not matter.
Tables that do not meet those requirements will not work with ipairs, use pairs instead.
Examples:
ipairsCompatable = {"AAA", "BBB", "CCC"}
ipairsCompatable2 = {[1] = "DDD", [2] = "EEE", [3] = "FFF"}
ipairsCompatable3 = {[3] = "work", [2] = "does", [1] = "this"}
notIpairsCompatable = {[2] = "this", [3] = "does", [4] = "not"}
notIpairsCompatable2 = {[2] = "this", [5] = "doesn't", [24] = "either"}
ipairs will go as far as it can with it's iterations but won't iterate over any other element in the table.
kindofIpairsCompatable = {[2] = 2, ["cool"] = "bro", [1] = 1, [3] = 3, [5] = 5 }
When printing these tables, these are the outputs. I've also included pairs outputs for comparison.
ipairs + ipairsCompatable
1 AAA
2 BBB
3 CCC
ipairs + ipairsCompatable2
1 DDD
2 EEE
3 FFF
ipairs + ipairsCompatable3
1 this
2 does
3 work
ipairs + notIpairsCompatable
pairs + notIpairsCompatable
2 this
3 does
4 not
ipairs + notIpairsCompatable2
pairs + notIpairsCompatable2
2 this
5 doesnt
24 either
ipairs + kindofIpairsCompatable
1 1
2 2
3 3
pairs + kindofIpairsCompatable
1 1
2 2
3 3
5 5
cool bro
Simply sitting on a delimiter
local str = 'one,two'
local regxEverythingExceptComma = '([^,]+)'
for x in string.gmatch(str, regxEverythingExceptComma) do
print(x)
end
For testing only two values, I'd personally do this:
if x ~= 0 and x ~= 1 then
print( "X must be equal to 1 or 0" )
return
end
If you need to test against more than two values, I'd stuff your choices in a table acting like a set, like so:
choices = {[0]=true, [1]=true, [3]=true, [5]=true, [7]=true, [11]=true}
if not choices[x] then
print("x must be in the first six prime numbers")
return
end
Again with the inverting, you could simply use the following code:
for k,v in pairs(t) do
if not isstring(k) then
-- do something to t[k] when k is not a string
end
for i=1,#target do
game.Players.target[i].Character:BreakJoints()
end
Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:
game.Players.target.1.Character:BreakJoints()
Which is completely incorrect.
c = game.Players:GetChildren()
Never use "Players:GetChildren()", it is not guaranteed to return only players.
Instead use:
c = Game.Players:GetPlayers()
if msg:lower()=="me" then
table.insert(people, source)
return people
Here you add the player's name in the list "people", where you in the other places adds the player object.
Fixed code:
local Admins = {"FakeNameHereSoNoStalkers"}
function Kill(Players)
for i,Player in ipairs(Players) do
if Player.Character then
Player.Character:BreakJoints()
end
end
end
function IsAdmin(Player)
for i,AdminName in ipairs(Admins) do
if Player.Name:lower() == AdminName:lower() then return true end
end
return false
end
function GetPlayers(Player,Msg)
local Targets = {}
local Players = Game.Players:GetPlayers()
if Msg:lower() == "me" then
Targets = { Player }
elseif Msg:lower() == "all" then
Targets = Players
elseif Msg:lower() == "others" then
for i,Plr in ipairs(Players) do
if Plr ~= Player then
table.insert(Targets,Plr)
end
end
else
for i,Plr in ipairs(Players) do
if Plr.Name:lower():sub(1,Msg:len()) == Msg then
table.insert(Targets,Plr)
end
end
end
return Targets
end
Game.Players.PlayerAdded:connect(function(Player)
if IsAdmin(Player) then
Player.Chatted:connect(function(Msg)
if Msg:lower():sub(1,6) == ":kill " then
Kill(GetPlayers(Player,Msg:sub(7)))
end
end)
end
end)
names = {'John', 'Joe', 'Steve'}
for names = 1, 3 do
print (names)
end
Try:
names = {'John','Joe','Steve'}
for i = 1,3 do
print(names[i])
end
you can use this solution:
items = { 'a', 'b' }
for k,v in pairs(items) do
if v == 'a' then
--do something
else
--do something
end
end
or
items = {'a', 'b'}
for k,v in pairs(items) do
while v do
if v == 'a' then
return found
else
break
end
end
end
return nothing
Just a little addition if one wants to parse a space separated text file line by line.
read_file = function (path)
local file = io.open(path, "rb")
if not file then return nil end
local lines = {}
for line in io.lines(path) do
local words = {}
for word in line:gmatch("%w+") do
table.insert(words, word)
end
table.insert(lines, words)
end
file:close()
return lines;
end
There are 2 options to find matching text; string.match
or string.find
.
Both of these perform a regex search on the string to find matches.
string.find()
string.find(subject string, pattern string, optional start position, optional plain flag)
Returns the startIndex
& endIndex
of the substring found.
The plain
flag allows for the pattern to be ignored and intead be interpreted as a literal. Rather than (tiger)
being interpreted as a regex capture group matching for tiger
, it instead looks for (tiger)
within a string.
Going the other way, if you want to regex match but still want literal special characters (such as .()[]+-
etc.), you can escape them with a percentage; %(tiger%)
.
You will likely use this in combination with string.sub
str = "This is some text containing the word tiger."
if string.find(str, "tiger") then
print ("The word tiger was found.")
else
print ("The word tiger was not found.")
end
string.match()
string.match(s, pattern, optional index)
Returns the capture groups found.
str = "This is some text containing the word tiger."
if string.match(str, "tiger") then
print ("The word tiger was found.")
else
print ("The word tiger was not found.")
end
Given your representation, your function is as efficient as can be done. Of course, as noted by others (and as practiced in languages older than Lua), the solution to your real problem is to change representation. When you have tables and you want sets, you turn tables into sets by using the set element as the key and true
as the value. +1 to interjay.
Concatenation:
The string concatenation operator in Lua is denoted by two dots ('..'). If both operands are strings or numbers, then they are converted to strings according to the rules mentioned in §2.2.1. Otherwise, the "concat" metamethod is called (see §2.8).
There's one way, but it might be disappointing: use an additional variable (or one of the table's field) for storing the count, and increase it every time you make an insertion.
count = 0
tbl = {}
tbl["test"] = 47
count = count + 1
tbl[1] = 48
count = count + 1
print(count) -- prints "2"
There's no other way, the # operator will only work on array-like tables with consecutive keys.
If your environment is Windows and you have access to system commands, you can get time of centiseconds precision with io.popen(command)
:
local handle = io.popen("echo %time%")
local result = handle:read("*a")
handle:close()
The result will hold string of hh:mm:ss.cc
format: (with trailing line break)
"19:56:53.90\n"
Note, it's in local timesone, so you probably want to extract only the .cc
part and combine it with epoch seconds from os.time()
.
If you have luasocket installed:
local socket = require 'socket'
socket.sleep(0.2)
I can second the previous posters enthusiasm for the Gideros Lua game engine, whilst focusing currently on Mobile (iOS and Android - Windows phone 8 is in the works), desktop support for Mac, PC (possibly Linux) is also planned for the not too distant future.

I use my own function to print the contents of a table but not sure how well it translates to your environment:
---A helper function to print a table's contents.
---@param tbl table @The table to print.
---@param depth number @The depth of sub-tables to traverse through and print.
---@param n number @Do NOT manually set this. This controls formatting through recursion.
function PrintTable(tbl, depth, n)
n = n or 0;
depth = depth or 5;
if (depth == 0) then
print(string.rep(' ', n).."...");
return;
end
if (n == 0) then
print(" ");
end
for key, value in pairs(tbl) do
if (key and type(key) == "number" or type(key) == "string") then
key = string.format("[\"%s\"]", key);
if (type(value) == "table") then
if (next(value)) then
print(string.rep(' ', n)..key.." = {");
PrintTable(value, depth - 1, n + 4);
print(string.rep(' ', n).."},");
else
print(string.rep(' ', n)..key.." = {},");
end
else
if (type(value) == "string") then
value = string.format("\"%s\"", value);
else
value = tostring(value);
end
print(string.rep(' ', n)..key.." = "..value..",");
end
end
end
if (n == 0) then
print(" ");
end
end
I agree with John on wrapping the sleep function. You could also use this wrapped sleep function to implement a pause function in lua (which would simply sleep then check to see if a certain condition has changed every so often). An alternative is to use hooks.
I'm not exactly sure what you mean with your third bulletpoint (don't commands usually complete before the next is executed?) but hooks may be able to help with this also.
See: Question: How can I end a Lua thread cleanly? for an example of using hooks.
You are looking for the insert
function, found in the table
section of the main library.
foo = {}
table.insert(foo, "bar")
table.insert(foo, "baz")
It should be noted that math.floor()
always rounds down, and therefore does not yield a sensible result for negative floating point values.
For example, -10.4 represented as an integer would usually be either truncated or rounded to -10. Yet the result of math.floor() is not the same:
math.floor(-10.4) => -11
For truncation with type conversion, the following helper function will work:
function tointeger( x )
num = tonumber( x )
return num < 0 and math.ceil( num ) or math.floor( num )
end

You're actually seeing the top margin of the #inner
element collapse into the top edge of the #outer
element, leaving only the #outer
margin intact (albeit not shown in your images). The top edges of both boxes are flush against each other because their margins are equal.
Here are the relevant points from the W3C spec:
8.3.1 Collapsing margins
In CSS, the adjoining margins of two or more boxes (which might or might not be siblings) can combine to form a single margin. Margins that combine this way are said to collapse, and the resulting combined margin is called a collapsed margin.
Adjoining vertical margins collapse [...]
Two margins are adjoining if and only if:
- both belong to in-flow block-level boxes that participate in the same block formatting context
- no line boxes, no clearance, no padding and no border separate them
- both belong to vertically-adjacent box edges, i.e. form one of the following pairs:
- top margin of a box and top margin of its first in-flow child
You can do any of the following to prevent the margin from collapsing:
- Float either of your
div
elements- Make either of your
div
elements inline blocks- Set
overflow
of#outer
toauto
(or any value other thanvisible
)
The reason the above options prevent the margin from collapsing is because:
- Margins between a floated box and any other box do not collapse (not even between a float and its in-flow children).
- Margins of elements that establish new block formatting contexts (such as floats and elements with 'overflow' other than 'visible') do not collapse with their in-flow children.
- Margins of inline-block boxes do not collapse (not even with their in-flow children).
The left and right margins behave as you expect because:
Horizontal margins never collapse.
In my case, I had the setting Override application root URL checked, on the Properties

tab. I was using that previously when I was running VS as an administrator, but now that I'm running it in a non-admin account, it causes the error.
Load data into a table in MySQL and specify columns:
LOAD DATA LOCAL INFILE 'file.csv' INTO TABLE t1
FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n'
(@col1,@col2,@col3,@col4) set name=@col4,id=@col2 ;
@col1,2,3,4 are variables to hold the csv file columns (assume 4 ) name,id are table columns.
To add just one more solution not yet mentioned, I had to say that using gitg's graphical search box was the simplest solution for me. It will select the first occurrence and you can find the next with Ctrl-G.
you can try just add

example :
version: '2'
services:
feedx:
build: web
ports:
- "127.0.0.1:8000:8000"
network_mode: "host"
list option available
network_mode: "bridge"
network_mode: "host"
network_mode: "none"
network_mode: "service:[service name]"

Hey i figured it out shortly after. For some reason I was just having a brain fart.

declarative program is just a data for its some more-or-less "universal" imperative implementation/vm.
pluses: specifying just a data, in some hardcoded (and checked) format, is simpler and less error-prone than specifying variant of some imperative algorithm directly. some complex specifications just cant be written directly, only in some DSL form. best and freq used in DSLs data structures is sets and tables. because you not have dependencies between elements/rows. and when you havent dependencies you have freedom to modify and ease of support. (compare for example modules with classes - with modules you happy and with classes you have fragile base class problem) all goods of declarativeness and DSL follows immediately from benefits of that data structures (tables and sets). another plus - you can change implementation of declarative language vm, if DSL is more-or-less abstract (well designed). make parallel implementation, for example. or port it to other os etc. all good specifed modular isolating interfaces or protocols gives you such freedom and easyness of support.
minuses: you guess right. generic (and parameterized by DSL) imperative algorithm/vm implementation may be slower and/or memory hungry than specific one. in some cases. if that cases is rare - just forget about it, let it be slow. if it's frequient - you always can extend your DSL/vm for that case. somewhere slowing down all other cases, sure...
P.S. Frameworks is half-way between DSL and imperative. and as all halfway solutions ... they combines deficiences, not benefits. they not so safe AND not so fast :) look at jack-of-all-trades haskell - it's halfway between strong simple ML and flexible metaprog Prolog and... what a monster it is. you can look at Prolog as a Haskell with boolean-only functions/predicates. and how simple its flexibility is against Haskell...
UPDATE `your_table` SET
`something` = IF(`id`="1","new_value1",`something`), `smth2` = IF(`id`="1", "nv1",`smth2`),
`something` = IF(`id`="2","new_value2",`something`), `smth2` = IF(`id`="2", "nv2",`smth2`),
`something` = IF(`id`="4","new_value3",`something`), `smth2` = IF(`id`="4", "nv3",`smth2`),
`something` = IF(`id`="6","new_value4",`something`), `smth2` = IF(`id`="6", "nv4",`smth2`),
`something` = IF(`id`="3","new_value5",`something`), `smth2` = IF(`id`="3", "nv5",`smth2`),
`something` = IF(`id`="5","new_value6",`something`), `smth2` = IF(`id`="5", "nv6",`smth2`)
// You just building it in php like
$q = 'UPDATE `your_table` SET ';
foreach($data as $dat){
$q .= '
`something` = IF(`id`="'.$dat->id.'","'.$dat->value.'",`something`),
`smth2` = IF(`id`="'.$dat->id.'", "'.$dat->value2.'",`smth2`),';
}
$q = substr($q,0,-1);
So you can update hole table with one query
// wrap it in jQuery, now it's a collection
var $elements = $(someHTML);
// append to the DOM
$("#myDiv").append($elements);
// do stuff, using the initial reference
$elements.effects("highlight", {}, 2000);
Thanks Darin, For me, to be able to post to the create method, It only worked after I modified the BindModel code to :
public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
if (!string.IsNullOrEmpty(displayFormat) && value != null)
{
DateTime date;
displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
// use the format specified in the DisplayFormat attribute to parse the date
if (DateTime.TryParse(value.AttemptedValue, CultureInfo.GetCultureInfo("en-GB"), DateTimeStyles.None, out date))
{
return date;
}
else
{
bindingContext.ModelState.AddModelError(
bindingContext.ModelName,
string.Format("{0} is an invalid date format", value.AttemptedValue)
);
}
}
return base.BindModel(controllerContext, bindingContext);
}
Hope this could help someone else...
If you are trying to create mapping in your edmx file to a "function Imports", this can result this error. Just clear the fields for insert, update and delete that is located in Mapping Details for a given entity in your edmx, and it should work. I hope I made it clear.
One possible solution which works for me:
Bravo!
In your code you are querying for the payment
element in default namespace, but in the XML response it is declared as in http://apilistener.envoyservices.com
namespace.
So, you are missing a namespace declaration:
$xml->registerXPathNamespace('envoy', 'http://apilistener.envoyservices.com');
Now you can use the envoy
namespace prefix in your xpath query:
xpath('//envoy:payment')
The full code would be:
$xml = simplexml_load_string($soap_response);
$xml->registerXPathNamespace('envoy', 'http://apilistener.envoyservices.com');
foreach ($xml->xpath('//envoy:payment') as $item)
{
print_r($item);
}
Note: I removed the soap
namespace declaration as you do not seem to be using it (it is only useful if you would use the namespace prefix in you xpath queries).
One of the reason I found for this error is 'Packet Size=xxxxx' in connection string. if the value of xxxx is too large, we will see this error. Either remove this value and let SQL server handle it or keep it low, depending on the network capabilities.
Meridian pertains to AM/PM, by setting it to false you're indicating you don't want AM/PM, therefore you want 24-hour clock implicitly.
$('#timepicker1').timepicker({showMeridian:false});
Try the Date
function. It will give you today's date in a MM/DD/YYYY format. If you're looking for today's date in the MM-DD-YYYY format try Date$
. Now()
also includes the current time (which you might not need). It all depends on what you need. :)
As I'm beginner for vba, I'm willing to get a deep knowledge of vba of how all excel in-built functions work form there back.
So as on the above question I have putted my basic efforts.
Function multi_add(a As Range, ParamArray b() As Variant) As Double
Dim ele As Variant
Dim i As Long
For Each ele In a
multi_add = a + ele.Value **- a**
Next ele
For i = LBound(b) To UBound(b)
For Each ele In b(i)
multi_add = multi_add + ele.Value
Next ele
Next i
End Function
- a: This is subtracted for above code cause a count doubles itself so what values you adds it will add first value twice.

Eclipse has built in JUnit functionality. Open your Run Configuration manager to create a test to run. You can also create JUnit Test Cases/Suites from New->Other.
If you are using the 'pylab' for interactive plotting you can set the labelsize at creation time with pylab.ylabel('Example', fontsize=40)
.
If you use pyplot
programmatically you can either set the fontsize on creation with ax.set_ylabel('Example', fontsize=40)
or afterwards with ax.yaxis.label.set_size(40)
.
For iPhone it works if you add also playsinline so:
<video width="320" height="240" autoplay loop muted playsinline>
<source src="movie.mp4" type="video/mp4" />
</video>
On Windows 10 the following worked for me. I added the following environment variables using Settings > Edit environment variables for your account:
SPARK_HOME=C:\Programming\spark-2.0.1-bin-hadoop2.7
PYTHONPATH=%SPARK_HOME%\python;%PYTHONPATH%
(change "C:\Programming\..." to the folder in which you have installed spark)
Another solution is to fix the socket location in the php.ini configuration file like this:
pdo_mysql.default_socket=/tmp/mysql.sock
Of course, the symlink works too, so its a matter of preference which one you change.
I got the way to remove a style attribute with pure JavaScript just to let you know the way of pure JavaScript
var bodyStyle = document.body.style;
if (bodyStyle.removeAttribute)
bodyStyle.removeAttribute('background-color');

bodyStyle.removeProperty('background-color');
Maybe you want set -e
:
www.davidpashley.com/articles/writing-robust-shell-scripts.html#id2382181:
This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. Again, for readability you may want to use set -o errexit.
Create a list of lists:
with open("/path/to/file") as file:
lines = []
for line in file:
# The rstrip method gets rid of the "\n" at the end of each line
lines.append(line.rstrip().split(","))
This XML file does not appear to have any style information associated with it. The document tree is shown below.
You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml
instead of text/html
and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.
In case of JSF/Facelets files which have the default extension of .xhtml
, that can in turn happen if the HTTP request hasn't invoked the FacesServlet
and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml
file extension which is in your Firefox configuration apparently by default interpreted as text/xml
.
You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern>
of the FacesServlet
as registered in webapp's web.xml
, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf
, then you need to open the page by /some.jsf
instead of /some.xhtml
. Alternatively, you can also just change the <url-pattern>
to *.xhtml
. This way you never need to fiddle with virtual URLs.
Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.
In the pgAdmin4, Right click on table select backup like this
After that into the backup dialog there is Dump options tab into that there is section queries you can select Use Insert Commands which include all insert queries as well in the backup.
I think pressing Q should work.
It is all about the right tool for the job. Neither is better 100% of the time. Both systems were created by man and have flaws. Sorry, but we suck and making perfect stuff.
I like dynamic typing because it gets out of my way, but yes runtime errors can creep up that I didn't plan for. Where as static typing may fix the aforementioned errors, but drive a novice(in typed languages) programmer crazy trying to cast between a constant char and a string.
To return a value from a VBScript function, assign the value to the name of the function, like this:
Function getNumber
getNumber = "423"
End Function
No, it is not a bad practice to break out of a loop when if certain desired condition is reached(like a match is found). Many times, you may want to stop iterations because you have already achieved what you want, and there is no point iterating further. But, be careful to make sure you are not accidentally missing something or breaking out when not required.
This can also add to performance improvement if you break the loop, instead of iterating over thousands of records even if the purpose of the loop is complete(i.e. may be to match required record is already done).
Example :
for (int j = 0; j < type.size(); j++) {
if (condition) {
// do stuff after which you want
break; // stop further iteration
}
}
Please note, the way that build parameters are accessed inside pipeline scripts (pipeline plugin) has changed. This approach:
getBinding().hasVariable("MY_PARAM")
Is not working anymore. Please try this instead:
def myBool = env.getEnvironment().containsKey("MY_BOOL") ? Boolean.parseBoolean("$env.MY_BOOL") : false
You're dealing with a python list, and sorting it is as easy as doing this.
my_list = ['Stem', 'constitute', 'Sedge', 'Eflux', 'Whim', 'Intrigue']
my_list.sort()
I use this function:
function formatcell($data, $num, $fill=" ") {
$data = trim($data);
$data=str_replace(chr(13),' ',$data);
$data=str_replace(chr(10),' ',$data);
// translate UTF8 to English characters
$data = iconv('UTF-8', 'ASCII//TRANSLIT', $data);
$data = preg_replace("/[\'\"\^\~\`]/i", '', $data);
// fill it up with spaces
for ($i = strlen($data); $i < $num; $i++) {
$data .= $fill;
}
// limit string to num characters
$data = substr($data, 0, $num);
return $data;
}
echo formatcell("YES UTF8 String Zürich", 25, 'x'); //YES UTF8 String Zürichxxx
echo formatcell("NON UTF8 String Zurich", 25, 'x'); //NON UTF8 String Zurichxxx
Check out my function in my blog http://www.unexpectedit.com/php/php-handling-non-english-characters-utf8
One gotcha I have found is where two objects contain references to each other (one example being a parent/child relationship with a convenience method on the parent to get all children).
These sorts of things are fairly common when doing Hibernate mappings for example.
If you include both ends of the relationship in your hashCode or equals tests it's possible to get into a recursive loop which ends in a StackOverflowException.
The simplest solution is to not include the getChildren collection in the methods.
Use ngModelChange
by breaking up the [(x)]
syntax into its two pieces, i.e., property databinding and event binding:
<input type="text" [ngModel]="mymodel" (ngModelChange)="valuechange($event)" />
{{mymodel}}
valuechange(newValue) {
mymodel = newValue;
console.log(newValue)
}
It works for the backspace key too.
The accepted answer no longer works. When running the command xcode-select --install
it tells you to use "Software Update" to install updates.
In this link is the updated method:
Open a Terminal and then:
cd /Library/Developer/CommandLineTools/Packages/
open macOS_SDK_headers_for_macOS_10.14.pkg
This will open an installation Wizard.
After updating to Mojave 10.15.1 it seems that using xcode-select --install
works as intended.
Is JSTL's join()
, what you searched for?
<c:set var="myVar" value="${fn:join(myParams.items, ' ')}" />
So, 10 years later this is still a thing :)
I've tried every answer on this page (ATOW)
and also some ILGenerator powered solutions (FastMember and Fast.Reflection).
But a compiled Lambda Expression seems to be the fastest.
At least for my use cases (on .Net Core 2.2).
This is what I am using for now:
public static class EnumerableExtensions {
internal static Func<TClass, object> CompileGetter<TClass>(string propertyName) {
var param = Expression.Parameter(typeof(TClass));
var body = Expression.Convert(Expression.Property(param, propertyName), typeof(object));
return Expression.Lambda<Func<TClass, object>>(body,param).Compile();
}
public static DataTable ToDataTable<T>(this IEnumerable<T> collection) {
var dataTable = new DataTable();
var properties = typeof(T)
.GetProperties(BindingFlags.Public | BindingFlags.Instance)
.Where(p => p.CanRead)
.ToArray();
if (properties.Length < 1) return null;
var getters = new Func<T, object>[properties.Length];
for (var i = 0; i < properties.Length; i++) {
var columnType = Nullable.GetUnderlyingType(properties[i].PropertyType) ?? properties[i].PropertyType;
dataTable.Columns.Add(properties[i].Name, columnType);
getters[i] = CompileGetter<T>(properties[i].Name);
}
foreach (var row in collection) {
var dtRow = new object[properties.Length];
for (var i = 0; i < properties.Length; i++) {
dtRow[i] = getters[i].Invoke(row) ?? DBNull.Value;
}
dataTable.Rows.Add(dtRow);
}
return dataTable;
}
}
Only works with properties (not fields) but it works on Anonymous Types.
def median(d):
d=np.sort(d)
n2=int(len(d)/2)
r=n2%2
if (r==0):
med=d[n2]
else:
med=(d[n2] + data[m+1]) / 2
return med
You should use a RelativeLayout and just drag them until it looks good :)
<ImageView
android:id="@+id/button_info"
android:layout_width="30dp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginRight="10dp"
android:contentDescription="@string/pizza"
android:src="@drawable/header_info_button" />
</RelativeLayout>
To get the exact output you requested, you can use the below:
CAST(DATEPART(YEAR, @Date) AS NVARCHAR(10)) + ' - Q' + CAST(DATEPART(QUARTER, @Date) AS NVARCHAR(10))
This will give you an outputs like: "2015 - Q1", "2013 - Q3", etc.
Header exists:
if (Request.Headers["XYZComponent"] != null)
or even better:
string xyzHeader = Request.Headers["XYZComponent"];
bool isXYZ;
if (bool.TryParse(xyzHeader, out isXYZ) && isXYZ)
which will check whether it is set to true. This should be fool-proof because it does not care on leading/trailing whitespace and is case-insensitive (bool.TryParse
does work on null
)
Addon: You could make this more simple with this extension method which returns a nullable boolean. It should work on both invalid input and null.
public static bool? ToBoolean(this string s)
{
bool result;
if (bool.TryParse(s, out result))
return result;
else
return null;
}
Usage (because this is an extension method and not instance method this will not throw an exception on null
- it may be confusing, though):
if (Request.Headers["XYZComponent"].ToBoolean() == true)
I suggest this one:
if [ "$a" = "$b" ]
Notice the white space between the openning/closing brackets and the variables and also the white spaces wrapping the '=' sign.
Also, be careful of your script header. It's not the same thing whether you use
#!/bin/bash
or
#!/bin/sh

In addition to solutions proposed, and in case you have a 1D range to 1D array, i prefer to process it through a function like below. The reason is simple: If for any reason your range is reduced to 1 element range, as far as i know the command Range().Value will not return a variant array but just a variant and you will not be able to assign a variant variable to a variant array (previously declared).
I had to convert a variable size range to a double array, and when the range was of 1 cell size, i was not able to use a construct like range().value so i proceed with a function like below.
Public Function Rng2Array(inputRange As Range) As Double()
Dim out() As Double
ReDim out(inputRange.Columns.Count - 1)
Dim cell As Range
Dim i As Long
For i = 0 To inputRange.Columns.Count - 1
out(i) = inputRange(1, i + 1) 'loop over a range "row"
Next
Rng2Array = out
End Function
Here's the correct solution which supports https and http:
# Redirect to www
RewriteCond %{HTTP_HOST} ^[^.]+\.[^.]+$
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
UPD.: for domains like .co.uk
, replace
RewriteCond %{HTTP_HOST} ^[^.]+\.[^.]+$
with
RewriteCond %{HTTP_HOST} ^[^.]+\.[^.]+\.[^.]+$
This is not JSON. JSON was designed to be simple; allowing arbitrary expressions is not simple.
In full JavaScript, I don't think you can do this directly. You cannot refer to this
until the object called obj
is fully constructed. So you need a workaround, that someone with more JavaScript-fu than I will provide.
The JPanel
is actually only a container where you can put different elements in it (even other JPanels
). So in your case I would suggest one big JPanel
as some sort of main container for your window. That main panel you assign a Layout
that suits your needs ( here is an introduction to the layouts).
After you set the layout to your main panel you can add the paint panel and the other JPanels you want (like those with the text in it..).
JPanel mainPanel = new JPanel();
mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS));
JPanel paintPanel = new JPanel();
JPanel textPanel = new JPanel();
mainPanel.add(paintPanel);
mainPanel.add(textPanel);
This is just an example that sorts all sub panels vertically (Y-Axis). So if you want some other stuff at the bottom of your mainPanel (maybe some icons or buttons) that should be organized with another layout (like a horizontal layout), just create again a new JPanel as a container for all the other stuff and set setLayout(new BoxLayout(mainPanel, BoxLayout.X_AXIS)
.
As you will find out, the layouts are quite rigid and it may be difficult to find the best layout for your panels. So don't give up, read the introduction (the link above) and look at the pictures – this is how I do it :)
Or you can just use NetBeans to write your program. There you have a pretty easy visual editor (drag and drop) to create all sorts of Windows and Frames. (only understanding the code afterwards is ... tricky sometimes.)
Since there are some many people interested in this question, I wanted to provide a complete example of how to layout a JFrame to make it look like OP wants it to.
The class is called MyFrame and extends swings JFrame
public class MyFrame extends javax.swing.JFrame{
// these are the components we need.
private final JSplitPane splitPane; // split the window in top and bottom
private final JPanel topPanel; // container panel for the top
private final JPanel bottomPanel; // container panel for the bottom
private final JScrollPane scrollPane; // makes the text scrollable
private final JTextArea textArea; // the text
private final JPanel inputPanel; // under the text a container for all the input elements
private final JTextField textField; // a textField for the text the user inputs
private final JButton button; // and a "send" button
public MyFrame(){
// first, lets create the containers:
// the splitPane devides the window in two components (here: top and bottom)
// users can then move the devider and decide how much of the top component
// and how much of the bottom component they want to see.
splitPane = new JSplitPane();
topPanel = new JPanel(); // our top component
bottomPanel = new JPanel(); // our bottom component
// in our bottom panel we want the text area and the input components
scrollPane = new JScrollPane(); // this scrollPane is used to make the text area scrollable
textArea = new JTextArea(); // this text area will be put inside the scrollPane
// the input components will be put in a separate panel
inputPanel = new JPanel();
textField = new JTextField(); // first the input field where the user can type his text
button = new JButton("send"); // and a button at the right, to send the text
// now lets define the default size of our window and its layout:
setPreferredSize(new Dimension(400, 400)); // let's open the window with a default size of 400x400 pixels
// the contentPane is the container that holds all our components
getContentPane().setLayout(new GridLayout()); // the default GridLayout is like a grid with 1 column and 1 row,
// we only add one element to the window itself
getContentPane().add(splitPane); // due to the GridLayout, our splitPane will now fill the whole window
// let's configure our splitPane:
splitPane.setOrientation(JSplitPane.VERTICAL_SPLIT); // we want it to split the window verticaly
splitPane.setDividerLocation(200); // the initial position of the divider is 200 (our window is 400 pixels high)
splitPane.setTopComponent(topPanel); // at the top we want our "topPanel"
splitPane.setBottomComponent(bottomPanel); // and at the bottom we want our "bottomPanel"
// our topPanel doesn't need anymore for this example. Whatever you want it to contain, you can add it here
bottomPanel.setLayout(new BoxLayout(bottomPanel, BoxLayout.Y_AXIS)); // BoxLayout.Y_AXIS will arrange the content vertically
bottomPanel.add(scrollPane); // first we add the scrollPane to the bottomPanel, so it is at the top
scrollPane.setViewportView(textArea); // the scrollPane should make the textArea scrollable, so we define the viewport
bottomPanel.add(inputPanel); // then we add the inputPanel to the bottomPanel, so it under the scrollPane / textArea
// let's set the maximum size of the inputPanel, so it doesn't get too big when the user resizes the window
inputPanel.setMaximumSize(new Dimension(Integer.MAX_VALUE, 75)); // we set the max height to 75 and the max width to (almost) unlimited
inputPanel.setLayout(new BoxLayout(inputPanel, BoxLayout.X_AXIS)); // X_Axis will arrange the content horizontally
inputPanel.add(textField); // left will be the textField
inputPanel.add(button); // and right the "send" button
pack(); // calling pack() at the end, will ensure that every layout and size we just defined gets applied before the stuff becomes visible
}
public static void main(String args[]){
EventQueue.invokeLater(new Runnable(){
@Override
public void run(){
new MyFrame().setVisible(true);
}
});
}
}
Please be aware that this is only an example and there are multiple approaches to layout a window. It all depends on your needs and if you want the content to be resizable / responsive. Another really good approach would be the GridBagLayout which can handle quite complex layouting, but which is also quite complex to learn.

By using Image.alpha_composite
, the solution by Yuji 'Tomita' Tomita become simpler. This code can avoid a tuple index out of range
error if png has no alpha channel.
from PIL import Image
png = Image.open(img_path).convert('RGBA')
background = Image.new('RGBA', png.size, (255,255,255))
alpha_composite = Image.alpha_composite(background, png)
alpha_composite.save('foo.jpg', 'JPEG', quality=80)

You don't really want to be reallocing memory every time you remove something. If you know the rough size of your deck then choose an appropriate size for your array and keep a pointer to the current end of the list. This is a stack.
If you don't know the size of your deck, and think it could get really big as well as keeps changing size, then you will have to do something a little more complex and implement a linked-list.
In C, you have two simple ways to declare an array.
On the stack, as a static array
int myArray[16]; // Static array of 16 integers
On the heap, as a dynamically allocated array
// Dynamically allocated array of 16 integers
int* myArray = calloc(16, sizeof(int));
Standard C does not allow arrays of either of these types to be resized. You can either create a new array of a specific size, then copy the contents of the old array to the new one, or you can follow one of the suggestions above for a different abstract data type (ie: linked list, stack, queue, etc).
I know i'm too late for the answer but for people reading this I found a much easier way for doing it
myVariable = 'This string is supposed to be raw \'
print(r'%s' %myVariable)
Based on @Attaque great answer, I propose a shorter simplified version of the datetime difference calculator:
seconds_mapping = {
'y': 31536000,
'm': 2628002.88, # this is approximate, 365 / 12; use with caution
'w': 604800,
'd': 86400,
'h': 3600,
'min': 60,
's': 1,
'mil': 0.001,
}
def get_duration(d1, d2, interval, with_reminder=False):
if with_reminder:
return divmod((d2 - d1).total_seconds(), seconds_mapping[interval])
else:
return (d2 - d1).total_seconds() / seconds_mapping[interval]
I've changed it to avoid declaring repetetive functions, removed the pretty print default interval and added support for milliseconds, weeks and ISO months (bare in mind months are just approximate, based on assumption that each month is equal to 365/12
).
Which produces:
d1 = datetime(2011, 3, 1, 1, 1, 1, 1000)
d2 = datetime(2011, 4, 1, 1, 1, 1, 2500)
print(get_duration(d1, d2, 'y', True)) # => (0.0, 2678400.0015)
print(get_duration(d1, d2, 'm', True)) # => (1.0, 50397.12149999989)
print(get_duration(d1, d2, 'w', True)) # => (4.0, 259200.00149999978)
print(get_duration(d1, d2, 'd', True)) # => (31.0, 0.0014999997802078724)
print(get_duration(d1, d2, 'h', True)) # => (744.0, 0.0014999997802078724)
print(get_duration(d1, d2, 'min', True)) # => (44640.0, 0.0014999997802078724)
print(get_duration(d1, d2, 's', True)) # => (2678400.0, 0.0014999997802078724)
print(get_duration(d1, d2, 'mil', True)) # => (2678400001.0, 0.0004999997244524721)
print(get_duration(d1, d2, 'y', False)) # => 0.08493150689687975
print(get_duration(d1, d2, 'm', False)) # => 1.019176965856293
print(get_duration(d1, d2, 'w', False)) # => 4.428571431051587
print(get_duration(d1, d2, 'd', False)) # => 31.00000001736111
print(get_duration(d1, d2, 'h', False)) # => 744.0000004166666
print(get_duration(d1, d2, 'min', False)) # => 44640.000024999994
print(get_duration(d1, d2, 's', False)) # => 2678400.0015
print(get_duration(d1, d2, 'mil', False)) # => 2678400001.4999995
I do something like this where I just give each table a string name to identify it in column A, and a count for column. Then I union them all so they stack. The result is pretty in my opinion - not sure how efficient it is compared to other options but it got me what I needed.
select 'table1', count (*) from table1
union select 'table2', count (*) from table2
union select 'table3', count (*) from table3
union select 'table4', count (*) from table4
union select 'table5', count (*) from table5
union select 'table6', count (*) from table6
union select 'table7', count (*) from table7;
Result:
-------------------
| String | Count |
-------------------
| table1 | 123 |
| table2 | 234 |
| table3 | 345 |
| table4 | 456 |
| table5 | 567 |

Here's another integrated method example maybe helpful.
from sklearn.datasets import load_iris
iris_X, iris_y = load_iris(return_X_y=True, as_frame=True)
type(iris_X), type(iris_y)
The data iris_X are imported as pandas DataFrame and the target iris_y are imported as pandas Series.
a fresh answer to a very old question:
starting from python 3.2 you can do this:
import os
path = '/home/dail/first/second/third'
os.makedirs(path, exist_ok=True)
thanks to the exist_ok
flag this will not even complain if the directory exists (depending on your needs....).
starting from python 3.4 (which includes the pathlib module) you can do this:
from pathlib import Path
path = Path('/home/dail/first/second/third')
path.mkdir(parents=True)
starting from python 3.5 mkdir
also has an exist_ok
flag - setting it to True
will raise no exception if the directory exists:
path.mkdir(parents=True, exist_ok=True)
Kyle's solution worked perfectly fine for me so I made my research in order to avoid any Js and CSS, but just sticking with HTML.
Adding a value of selected
to the item we want to appear as a header forces it to show in the first place as a placeholder.
Something like:
<option selected disabled>Choose here</option>
The complete markup should be along these lines:
<select>
<option selected disabled>Choose here</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>
</select>
You can take a look at this fiddle, and here's the result:
If you do not want the sort of placeholder text to appear listed in the options once a user clicks on the select box just add the hidden
attribute like so:
<select>
<option selected disabled hidden>Choose here</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>
</select>
Check the fiddle here and the screenshot below.
Here is the solution:
<select>
<option style="display:none;" selected>Select language</option>
<option>Option 1</option>
<option>Option 2</option>
</select>
Wrap your to be deleted contents within a ptag, then you can do something like this:
$(function(){
$("td").click(function(){ console.log($("td").find("p"));
$("td").find("p").remove(); });
});

I switched back to "Automatic" on the build settings provisioning profile for "Debug" and left the release certificate profile unchanged, mine worked. Tried the other answers. nothing worked. Didn't want to have to reconfigure my certificates. Automatic on the provisioning profile did the trick
in my case, i was sure that the action is correct, but i was passing wrong URL, i passed the website link without the http:// in it's beginning, so it caused the same issue, here is my manifest (part of it)
<activity
android:name=".MyBrowser"
android:label="MyBrowser Activity" >
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="com.dsociety.activities.MyBrowser" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="http" />
</intent-filter>
</activity>
when i code the following, the same Exception is thrown at run time :
Intent intent = new Intent();
intent.setAction("com.dsociety.activities.MyBrowser");
intent.setData(Uri.parse("www.google.com")); // should be http://www.google.com
startActivity(intent);
If you really want to compute the key of the next insert before inserting the row (which is in my opinion not a very good idea), then I would suggest that you use the maximum currently used id plus one:
SELECT MAX(id) + 1 FROM table
But I would suggest that you let MySQL create the id itself (by using a auto-increment column) and using LAST_INSERT_ID()
to get it from the DBMS. To do this, use a transaction in which you execute the insert and then query for the id like:
INSERT INTO table (col1) VALUES ("Text");
SELECT LAST_INSERT_ID();
The returnset now contains only one column which holds the id of the newly generated row.
What if your program does not know upfront how much memory to allocate (hence you cannot use stack variables). Say linked lists, the lists can grow without knowing upfront what is its size. So allocating on a heap makes sense for a linked list when you are not aware of how many elements would be inserted into it.
The Rectangle method
The simplest and most reliable way I've found of achieving worksheets/page-breaks is with use of the rectangle tool.
Group your page within rectangles or a single rectangle that fills the page in a sub-report, as follows:
The quickest way I've found of placing the rectangle is to draw it around the objects you wish to place in the rectangle.
Right click and in the layout menu, send the rectangle to back.
Select all your objects and drag them slightly, but be sure they land in the same place they were. They will all now be in the rectangle.
In the rectangle properties you can set the page-break to occur at the start or end of the rectangle and name of the page can be based on an expression.
The worksheets will be named the same as the name of the page.
Duplicate names will have a number in brackets suffix.
Note: Ensure that the names are valid worksheet names.
i had a similar problem where i was trying to focus on a txt area in an iframe loaded from another page. in most cases it work. There was an issue where it would fire in FF when the iFrame was loaded but before it was visible. so the focus never seemed to be set correctly.
i worked around this with a simular solution to cheeming's answer above
var iframeID = document.getElementById("modalIFrame");
//focus the IFRAME element
$(iframeID).focus();
//use JQuery to find the control in the IFRAME and set focus
$(iframeID).contents().find("#emailTxt").focus();
When you deploy a Java EE web application (using frameworks or not),its structure must follow some requirements/specifications. These specifications come from :
- The servlet container (e.g Tomcat)
- Java Servlet API
- Your application domain
Java Servlet API requirements
Java Servlet API states that your root application directory must have the following structure :
ApplicationName
|
|--META-INF
|--WEB-INF
|_web.xml <-- Here is the configuration file of your web app(where you define servlets, filters, listeners...)
|_classes <--Here goes all the classes of your webapp, following the package structure you defined. Only
|_lib <--Here goes all the libraries (jars) your application need
These requirements are defined by Java Servlet API.
3. Your application domain
Now that you've followed the requirements of the Servlet container(or application server) and the Java Servlet API requirements, you can organize the other parts of your webapp based upon what you need.
- You can put your resources (JSP files, plain text files, script files) in your application root directory. But then, people can access them directly from their browser, instead of their requests being processed by some logic provided by your application. So, to prevent your resources being directly accessed like that, you can put them in the WEB-INF directory, whose contents is only accessible by the server.
-If you use some frameworks, they often use configuration files. Most of these frameworks (struts, spring, hibernate) require you to put their configuration files in the classpath (the "classes" directory).
A cleaner (but less verbose, and perhaps not as preferred) alternative to user454322's answer on Java 6 (i.e., Android) would be to catch all Exception
s and re-throw RuntimeException
s. This wouldn't work if you're planning on catching other types of exceptions further up the stack (unless you also re-throw them), but will effectively catch all checked exceptions.
For instance:
try {
// CODE THAT THROWS EXCEPTION
} catch (Exception e) {
if (e instanceof RuntimeException) {
// this exception was not expected, so re-throw it
throw e;
} else {
// YOUR CODE FOR ALL CHECKED EXCEPTIONS
}
}
That being said, for verbosity, it might be best to set a boolean or some other variable and based on that execute some code after the try-catch block.
One new and update answer: Many apps that were removed this October(2018) for the lack of Privacy Policy are unable to receive ads after they get back in Play Store. You must use this form to request a "reset" for that app's ads. https://support.google.com/admob/contact/appeal_policy_violation
Took me a few days to realize and find the answer. Hope you get your ads back.
If you want to build Java EE applications, it's best to use Eclipse IDE for Java EE. It has editors from HTML to JSP/JSF, Javascript. It's rich for webapps development, and provide plugins and tools to develop Java EE applications easily (all bundled).
Eclipse Classic is basically the full featured Eclipse without the Java EE part.
The Best way worked for me, was using Align
.
I needed to make the profile picture of a user in the bottom center of the Cover picture.
return Container(
height: 220,
color: Colors.red,
child: Stack(
children: [
Container(
height: 160,
color: Colors.yellow,
),
Align(
alignment: Alignment.bottomCenter,
child: UserProfileImage(),
),
],
),
);
This worked like a charm.
Others have commented on the (incorrect) use of 2/11
to specify the desired interval.
I personally however prefer writing things like that using ANSI interval
literals which makes reading the query much easier:
sysdate - interval '2' hour
It also has the advantage of being portable, many DBMS support this. Plus I don't have to fire up a calculator to find out how many hours the expression means - I'm pretty bad with mental arithmetics ;)
Try this:
window.open(url, '_blank');
This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)
You have to replace string line
QString line = in.readLine();
into while:
QFile file("/home/hamad/lesson11.txt");
if(!file.open(QIODevice::ReadOnly)) {
QMessageBox::information(0, "error", file.errorString());
}
QTextStream in(&file);
while(!in.atEnd()) {
QString line = in.readLine();
QStringList fields = line.split(",");
model->appendRow(fields);
}
file.close();
Press Ctrl+Shift+T in the code editor. It will show you popup with suggestion to create a test.
Mac OS: ? Cmd+Shift+T
The most easy way to do is copy innerHTML of that element to tmp variable and make it empty, then append new element, and after that copy back tmp variable to it. Here is an example I used to add jquery script to top of head.
var imported = document.createElement('script');
imported.src = 'http://code.jquery.com/jquery-1.7.1.js';
var tmpHead = document.head.innerHTML;
document.head.innerHTML = "";
document.head.append(imported);
document.head.innerHTML += tmpHead;
That simple :)
In the actual version this Option ist under Editor: Render Whitespace
Works Fine. Try this,
private void addImageButton_Click(object sender, EventArgs e)
{
OpenFileDialog of = new OpenFileDialog();
//For any other formats
of.Filter = "Image Files (*.bmp;*.jpg;*.jpeg,*.png)|*.BMP;*.JPG;*.JPEG;*.PNG";
if (of.ShowDialog() == DialogResult.OK)
{
pictureBox1.ImageLocation = of.FileName;
}
}
Try this
string[] keys = Request.Form.AllKeys;
var value = "";
for (int i= 0; i < keys.Length; i++)
{
// here you get the name eg test[0].quantity
// keys[i];
// to get the value you use
value = Request.Form[keys[i]];
}
I ended up using (note the '.log' filename and the single quotes around 'myfilename_'):
<rollingStyle value="Date" />
<datePattern value="'myfilename_'yyyy-MM-dd"/>
<preserveLogFileNameExtension value="true" />
<staticLogFileName value="false" />
<file type="log4net.Util.PatternString" value="c:\\Logs\\.log" />
This gives me:
myfilename_2015-09-22.log
myfilename_2015-09-23.log
.
.
You can use:
<input type="number" step="any" min="0" max="100" value="22.33">
As part of Spring 4.1.1
onwards you now have full support of Java 8 Optional
(original ticket) therefore in your example both requests will go via your single mapping endpoint as long as you replace required=false
with Optional for your 3 params logout, name, password:
@RequestMapping (value = "/submit/id/{id}", method = RequestMethod.GET,
produces="text/xml")
public String showLoginWindow(@PathVariable("id") String id,
@RequestParam(value = "logout") Optional<String> logout,
@RequestParam("name") Optional<String> username,
@RequestParam("password") Optional<String> password,
@ModelAttribute("submitModel") SubmitModel model,
BindingResult errors) throws LoginException {...}
That's not JSON. It's just Javascript objects, and has nothing at all to do with JSON.
You can use brackets to set the properties dynamically. Example:
var obj = {};
obj['name'] = value;
obj['anotherName'] = anotherValue;
This gives exactly the same as creating the object with an object literal like this:
var obj = { name : value, anotherName : anotherValue };
If you have already added the object to the ips
collection, you use one pair of brackets to access the object in the collection, and another pair to access the propery in the object:
ips[ipId] = {};
ips[ipId]['name'] = value;
ips[ipId]['anotherName'] = anotherValue;
Notice similarity with the code above, but that you are just using ips[ipId]
instead of obj
.
You can also get a reference to the object back from the collection, and use that to access the object while it remains in the collection:
ips[ipId] = {};
var obj = ips[ipId];
obj['name'] = value;
obj['anotherName'] = anotherValue;
You can use string variables to specify the names of the properties:
var name = 'name';
obj[name] = value;
name = 'anotherName';
obj[name] = anotherValue;
It's value of the variable (the string) that identifies the property, so while you use obj[name]
for both properties in the code above, it's the string in the variable at the moment that you access it that determines what property will be accessed.
It returns English name of the month. 04 returns APRIL and so on.
String englishMonth (int month){
return Month.of(month);
}
I am a fan of Cmder, a package including clink, conemu, msysgit, and some cosmetic enhancements.

You actually don't need ajax at all for this. If you just set "download.php" as the href on the button, or, if it's not a link use:
window.location = 'download.php';
The browser should recognise the binary download and not load the actual page but just serve the file as a download.
I didn't find a complete answer here

You should install your preferred language
Secondly
Go to Tools -> Options
2.Select International Settings in Environment
3.click on Menu and select you preferred language

Just put a line break into your text.
You don't add lines as a method. Multiline just supports the use of line breaks.
I used the original solution but made a couple of changes:
First, I used getJSON()
instead of get()
because I was loading a json script. Next I added the trigger behaviour of hover to fix the sticky pop over issue.
$('*[data-poload]').on('mouseover',function() {
var e=$(this);
$.getJSON(e.data('poload'), function(data){
var tip;
$.each(data, function (index, value) {
tip = this.tip;
e.popover({content: tip, html: true, container: 'body', trigger: 'hover'}).popover('show');
});
});
});
while true ; do
...
if [ something ]; then
break
fi
done
As of now, it's possible to remove all consecutive duplicate lines with Notepad in-built functionality. Sort the lines first:
Edit > Line Operations > "Sort lines lexicographically",
then
Edit > Line Operations > "Remove Consecutive Duplicate Lines".
The regex solution suggested above didn't remove all duplicate lines for me, but just the consecutive ones as well.
Make Executable your jar and after that double click on it on Mac OS then it works successfully.
sudo chmod +x filename.jar
Try this, I hope this works.
overflow:hidden
does not always mean that the element is hidden or non existent in the DOM, it means that the overflowing chars that do not fit in the element are being trimmed. Basically it means that do not show scrollbar even if it should be showed, so in your case the link with text
Plastic Spiral Bind
could possibly be shown as "Plastic Spir..." or similar. So it is possible, that this linkText indeed is non existent.
So you can probably try:
driver.findElement(By.partialLinkText("Plastic ")).click();
or xpath:
//a[contains(@title, \"Plastic Spiral Bind\")]
Could it be simpler?!

That's an old question, I know. But, according to me, it is missing proper answer.
The actual / optimal workflow here would be to incorporate SVN's post-commit hook so it triggers Jenkins job after the actual commit is issued only, not in any other case. This way you avoid unneeded polls on your SCM system.
You may find the following links interesting:
In case of my setup in the corp's SVN server, I utilize the following (censored) script as a post-commit hook on the subversion server side:
#!/bin/sh
# POST-COMMIT HOOK
REPOS="$1"
REV="$2"
#TXN_NAME="$3"
LOGFILE=/var/log/xxx/svn/xxx.post-commit.log
MSG=$(svnlook pg --revprop $REPOS svn:log -r$REV)
JENK="http://jenkins.xxx.com:8080/job/xxx/job/xxx/buildWithParameters?token=xxx&username=xxx&cause=xxx+r$REV"
JENKtest="http://jenkins.xxx.com:8080/view/all/job/xxx/job/xxxx/buildWithParameters?token=xxx&username=xxx&cause=xxx+r$REV"
echo post-commit $* >> $LOGFILE 2>&1
# trigger Jenkins job - xxx
svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -qP "branches/xxx/xxx/Source"
if test 0 -eq $? ; then
echo $(date) - $REPOS - $REV: >> $LOGFILE
svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -P "branches/xxx/xxx/Source" >> $LOGFILE 2>&1
echo logmsg: $MSG >> $LOGFILE 2>&1
echo curl -qs $JENK >> $LOGFILE 2>&1
curl -qs $JENK >> $LOGFILE 2>&1
echo -------- >> $LOGFILE
fi
# trigger Jenkins job - xxxx
svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -qP "branches/xxx_TEST"
if test 0 -eq $? ; then
echo $(date) - $REPOS - $REV: >> $LOGFILE
svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -P "branches/xxx_TEST" >> $LOGFILE 2>&1
echo logmsg: $MSG >> $LOGFILE 2>&1
echo curl -qs $JENKtest >> $LOGFILE 2>&1

This code works fine
Create your shell script as login.sh
in your $HOME folder.
Paste the following one-line script into Script Editor:
do shell script "$HOME/login.sh"
Then save it as an application.
Finally add the application to your login items.
If you want to make the script output visual, you can swap step 2 for this:
tell application "Terminal"
activate
do script "$HOME/login.sh"
end tell
If multiple commands are needed something like this can be used:
tell application "Terminal"
activate
do script "cd $HOME"
do script "./login.sh" in window 1
end tell
Using jQuery:
$('#Button').click(function(){
$(this).addClass("active");
});
This way, you don't have to pollute your HTML markup with onclick
handlers.
If your icon is based on the text in the block (ligatures) rather the class of the block then the following will work. This example uses the Google Material Icons '+' and '-' icons as part of MaterializeCSS.
<a class="btn-class"><i class="material-icons">add</i></a>
$('.btn-class').on('click',function(){
if ($(this).find('i').text() == 'add'){
$(this).find('i').text('remove');
} else {
$(this).find('i').text('add');
}
});
Edit: Added missing );
needed for this to function properly.
It also works for JQuery post 1.9 where toggling of functions was deprecated.
Actually, I found a somewhat quirky way to do this. Add the protocol to your web.config, but inside a location element. Specify the webservice location as the path attribute, like so:
<location path="YourWebservice.asmx">
<system.web>
<webServices>
<protocols>
<add name="HttpGet"/>
<add name="HttpPost"/>
</protocols>
</webServices>
</system.web>
</location>

UNION
SELECT CONVERT(VARCHAR(25),DATEADD(dd,-(DAY(DATEADD(mm,1,@date))),
DATEADD(mm,1,@date)),105),
'Last Day of Current Month'
GO

There are many good answers, but I would use StringUtils
from commons-lang. I find StringUtils.substringBefore()
more readable than the alternatives:
String result = StringUtils.substringBefore("34.1 -118.33\n<!--ABCDEFG-->", "\n");
Binding background image style using a dynamic value from v-for loop could be done like this.

I found this maven
repo where you could download from directly a zip
file containing all the jars you need.
The solution I prefer is using Maven
, it is easy and you don't have to download each jar
alone. You can do it with the following steps:
Create an empty folder anywhere with any name you prefer, for example spring-source
Create a new file named pom.xml
Copy the xml below into this file
Open the spring-source
folder in your console
Run mvn install
After download finished, you'll find spring jars in /spring-source/target/dependencies
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Also, if you need to download any other spring project, just copy the dependency
configuration from its corresponding web page.
For example, if you want to download Spring Web Flow
jars, go to its web page, and add its dependency
configuration to the pom.xml
dependencies
, then run mvn install
again.

I updated the plugin with the nightly builds: http://www.eclipse.org/egit/download/
With an update, it worked for me. (Eclipse Helios, Mac OS X)
Well So I was trying to fix this error. And none worked for me. I was not able to figure out solution. Scenario:
I was just going to made a Navigation Drawer Project
inside Android Studio 2.1.2
And when I try to change the default Android icon in nav_header_main.xml
I was getting some weird errors. I figured out that I was droping my PNG
logo into the ...\app\src\main\res\drawable-21
. When I try to put my PNG logo in ...\app\src\main\res\drawable
bam! All weird errors go away.
Following are some of stack trace when I was putting PNG into drawable-21

I got similar error (my app crashes) after I renamed something in strings.xml
and forgot to modify other files (a preference xml resource file and java code).
IDE (android studio) didn't showed any errors. But, after I repaired my xml files and java code, app ran okay. So, maybe there are some small mistakes in your xml files or constants.

There are three tables- Equities(coulmns: ID,ISIN) and Bond(coulmns: ID,ISIN). Third table Securities(coulmns: ID,ISIN) contains all data from Equities and Bond tables. Write SQL queries to validate below: (1) Securities table should contain all the data from Equities and Bonds tables. (2) Securities table should not contain any data other than present in Equities and Bonds tables
queryForMap
is appropriate if you want to get a single row. You are selecting without a where
clause, so you probably want to queryForList
. The error is probably indicative of the fact that queryForMap
wants one row, but you query is retrieving many rows.
Check out the docs. There is a queryForList
that takes just sql; the return type is a
List<Map<String,Object>>
.
So once you have the results, you can do what you are doing. I would do something like
List results = template.queryForList(sql);
for (Map m : results){
m.get('userid');
m.get('username');
}
I'll let you fill in the details, but I would not iterate over keys in this case. I like to explicit about what I am expecting.
If you have a User
object, and you actually want to load User instances, you can use the queryForList
that takes sql and a class type
queryForList(String sql, Class<T> elementType)
(wow Spring has changed a lot since I left Javaland.)
Use below code for passing string from one jsp to another jsp

Ok - for me the source of the problem was in serialisation/deserialisation. The object that was being sent and received was as follows where the code is submitted and the code and maskedPhoneNumber is returned.
@ApiObject(description = "What the object is for.")
@JsonIgnoreProperties(ignoreUnknown = true)
public class CodeVerification {
@ApiObjectField(description = "The code which is to be verified.")
@NotBlank(message = "mandatory")
private final String code;
@ApiObjectField(description = "The masked mobile phone number to which the code was verfied against.")
private final String maskedMobileNumber;
public codeVerification(@JsonProperty("code") String code, String maskedMobileNumber) {
this.code = code;
this.maskedMobileNumber = maskedMobileNumber;
}
public String getcode() {
return code;
}
public String getMaskedMobileNumber() {
return maskedMobileNumber;
}
}
The problem was that I didn't have a JsonProperty defined for the maskedMobileNumber in the constructor. i.e. Constructor should have been
public codeVerification(@JsonProperty("code") String code, @JsonProperty("maskedMobileNumber") String maskedMobileNumber) {
this.code = code;
this.maskedMobileNumber = maskedMobileNumber;
}
A useful case for using lambdas is to improve the readability of long list comprehensions.
In this example loop_dic
is short for clarity but imagine loop_dic
being very long. If you would just use a plain value that includes i
instead of the lambda version of that value you would get a NameError
.
>>> lis = [{"name": "Peter"}, {"name": "Josef"}]
>>> loop_dic = lambda i: {"name": i["name"] + " Wallace" }
>>> new_lis = [loop_dic(i) for i in lis]
>>> new_lis
[{'name': 'Peter Wallace'}, {'name': 'Josef Wallace'}]
Instead of
>>> lis = [{"name": "Peter"}, {"name": "Josef"}]
>>> new_lis = [{"name": i["name"] + " Wallace"} for i in lis]
>>> new_lis
[{'name': 'Peter Wallace'}, {'name': 'Josef Wallace'}]
In Linux, I normally use this command to recursively grep for a particular text within a dir
grep -rni "string" *
where,
r = recursive i.e, search subdirectories within the current directory
n = to print the line numbers to stdout
i = case insensitive search
Here is a vbs script that was passed down to me:
Set servicelist = GetObject("winmgmts:").InstancesOf ("Win32_Service")
for each service in servicelist
sname = lcase(service.name)
If sname = "NameOfMyService" Then
msgbox(sname)
service.delete ' the internal name of your service
end if
next
you are doing several things wrong. The explanation follows the corrected code:
<label id="LblTextCount"></label>
<textarea name="text" onKeyPress="checkLength(this, 512, 'LblTextCount')">
</textarea>
Note the quotes around the id.
function checkLength(object, maxlength, label) {
charsleft = (maxlength - object.value.length);
// never allow to exceed the specified limit
if( charsleft < 0 ) {
object.value = object.value.substring(0, maxlength-1);
}
// set the value of charsleft into the label
document.getElementById(label).innerHTML = charsleft;
}
First, on your key press event you need to send the label id as a string for it to read correctly. Second, InnerHTML has a lowercase i. Lastly, because you sent the function the string id you can get the element by that id.
Let me know how that works out for you
EDIT Not that by not declaring charsleft as a var, you are implicitly creating a global variable. a better way would be to do the following when declaring it in the function:
var charsleft = ....
Here is a little more fun. I've found that very often NumPy does exactly what I wish it would do - sometimes it's faster for me to just try things than it is to read the docs. Actually a mixture of both is best.
I think your answer is fine (and it's OK to accept it if you like). This is just "extra".
import numpy as np
a = np.arange(4,10).reshape(2,3)
wh = np.where(a>7)
gt = a>7
x = np.where(gt)
print "wh: ", wh
print "gt: ", gt
print "x: ", x
gives:
wh: (array([1, 1]), array([1, 2]))
gt: [[False False False]
[False True True]]
x: (array([1, 1]), array([1, 2]))
... but:
print "a[wh]: ", a[wh]
print "a[gt] ", a[gt]
print "a[x]: ", a[x]
gives:
a[wh]: [8 9]
a[gt] [8 9]
a[x]: [8 9]
So my question is: Is there a way to tell the compiler that a long long int is the also a int64_t, just like long int is?
This is a good question or problem, but I suspect the answer is NO.
Also, a long int
may not be a long long int
.
# if __WORDSIZE == 64 typedef long int int64_t; # else __extension__ typedef long long int int64_t; # endif
I believe this is libc. I suspect you want to go deeper.
In both 32-bit compile with GCC (and with 32- and 64-bit MSVC), the output of the program will be:
int: 0 int64_t: 1 long int: 0 long long int: 1
32-bit Linux uses the ILP32 data model. Integers, longs and pointers are 32-bit. The 64-bit type is a long long
.
Microsoft documents the ranges at Data Type Ranges. The say the long long
is equivalent to __int64
.
However, the program resulting from a 64-bit GCC compile will output:
int: 0 int64_t: 1 long int: 1 long long int: 0
64-bit Linux uses the LP64
data model. Longs are 64-bit and long long
are 64-bit. As with 32-bit, Microsoft documents the ranges at Data Type Ranges and long long is still __int64
.
There's a ILP64
data model where everything is 64-bit. You have to do some extra work to get a definition for your word32
type. Also see papers like 64-Bit Programming Models: Why LP64?
But this is horribly hackish and does not scale well (actual functions of substance, uint64_t, etc)...
Yeah, it gets even better. GCC mixes and matches declarations that are supposed to take 64 bit types, so its easy to get into trouble even though you follow a particular data model. For example, the following causes a compile error and tells you to use -fpermissive
:
#if __LP64__
typedef unsigned long word64;
#else
typedef unsigned long long word64;
#endif
// intel definition of rdrand64_step (http://software.intel.com/en-us/node/523864)
// extern int _rdrand64_step(unsigned __int64 *random_val);
// Try it:
word64 val;
int res = rdrand64_step(&val);
It results in:
error: invalid conversion from `word64* {aka long unsigned int*}' to `long long unsigned int*'
So, ignore LP64
and change it to:
typedef unsigned long long word64;
Then, wander over to a 64-bit ARM IoT gadget that defines LP64
and use NEON:
error: invalid conversion from `word64* {aka long long unsigned int*}' to `uint64_t*'
Of course if you're lazy like me, you could just do this:
Declare @Ids varchar(50) Set @Ids = ',1,2,3,5,4,6,7,98,234,'
Select * from sometable
where Charindex(','+cast(tableid as varchar(8000))+',', @Ids) > 0
\s
matches whitespace (spaces, tabs and new lines). \S
is negated \s
.
Until we get SERVER-863 keeping the field names as short as possible is advisable especially where you have a lot of records.
Depending on your use case, field names can have a huge impact on storage. Cant understand why this is not a higher priority for MongoDb, as this will have a positive impact on all users. If nothing else, we can start being more descriptive with our field names, without thinking twice about bandwidth & storage costs.
Please do vote.
You can enable NuGet packages and update you dlls. so that it work. or you can update the package manually by going through the package manager in your vs if u know which version you require for your solution.

Mozilla recently released the awesome L20n or localization 2.0. In their own words L20n is
an open source, localization-specific scripting language used to process gender, plurals, conjugations, and most of the other quirky elements of natural language.
Their js implementation is on the github L20n repository.
Some time, While executing insert query, we are facing:
Column not allowed here
error. Because of quote might missing in the string parameters. Add quote in the string params and try to execute.
Try this:
INSERT INTO LOCATION VALUES('PQ95VM','HAPPY_STREET','FRANCE');
or
INSERT INTO LOCATION (ID, FIRST_NAME, LAST_NAME) VALUES('PQ95VM','HAPPY_STREET','FRANCE');
You can read here about the behaviour of attributes in many different browsers, including IE.
element.setAttribute()
should do the trick, even in IE. Did you try it? If it doesn't work, then maybe
element.attributeName = 'value'
might work.
Building on the answer posted by maxspan, I've put together a minimal sample project on GitHub showing all the working parts.
Basically, we just add an Application_Error
method to global.asax.cs to intercept the exception and give us an opportunity to redirect (or more correctly, transfer request) to a custom error page.
protected void Application_Error(Object sender, EventArgs e)
{
// See http://stackoverflow.com/questions/13905164/how-to-make-custom-error-pages-work-in-asp-net-mvc-4
// for additional context on use of this technique
var exception = Server.GetLastError();
if (exception != null)
{
// This would be a good place to log any relevant details about the exception.
// Since we are going to pass exception information to our error page via querystring,
// it will only be practical to issue a short message. Further detail would have to be logged somewhere.
// This will invoke our error page, passing the exception message via querystring parameter
// Note that we chose to use Server.TransferRequest, which is only supported in IIS 7 and above.
// As an alternative, Response.Redirect could be used instead.
// Server.Transfer does not work (see https://support.microsoft.com/en-us/kb/320439 )
Server.TransferRequest("~/Error?Message=" + exception.Message);
}
}
Error Controller:
/// <summary>
/// This controller exists to provide the error page
/// </summary>
public class ErrorController : Controller
{
/// <summary>
/// This action represents the error page
/// </summary>
/// <param name="Message">Error message to be displayed (provided via querystring parameter - a design choice)</param>
/// <returns></returns>
public ActionResult Index(string Message)
{
// We choose to use the ViewBag to communicate the error message to the view
ViewBag.Message = Message;
return View();
}
}
Error page View:
<!DOCTYPE html>
<html>
<head>
<title>Error</title>
</head>
<body>
<h2>My Error</h2>
<p>@ViewBag.Message</p>
</body>
</html>
Nothing else is involved, other than disabling/removing filters.Add(new HandleErrorAttribute())
in FilterConfig.cs
public class FilterConfig
{
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
//filters.Add(new HandleErrorAttribute()); // <== disable/remove
}
}
While very simple to implement, the one drawback I see in this approach is using querystring to deliver exception information to the target error page.
There are a lot of things to consider when validating a phone number if you really think about it. (especially international) so using a package is better than the accepted answer by far, and if you want something simple like a regex I would suggest using something better than what @SlateEntropy suggested. (something like A comprehensive regex for phone number validation)
IF your input is String then I recommend you to store the String into a double and then convert the double to the long.
String str = "123.45";
Double a = Double.parseDouble(str);
long b = Math.round(a);
The easiest method is really good but you don't get a standard Java project, i.e., the .java and .class files separated in different folders.
To get this very easily:
<Enter>
and that's it.exec('wget http://<url to the php script>')
worked for me.
It enable me to integrate two php files that were designed as web pages and run them as code to do work without affecting the calling page
I did it! Using <intent-filter>
. Put the following into your manifest file:
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:host="www.youtube.com" android:scheme="http" />
</intent-filter>
This works perfectly!
Looks like when upgrading to OS X El Capitain, the /usr/local directory is modified in multiple ways :
[Edit] There's also a preliminary thing to do : upgrade Xcode...
$ sudo chown -R $(whoami):admin /usr/local
This will fix permissions on the /usr/local
directory which will then help both gem install
and brew install|link|...
commands working properly.
Make sure you have fixed the permissions of the /usr/local
directory (see #1 above)
First try to reinstall your gem using :
sudo gem install <gemname>
Note that it will install the latest version of the specified gem.
If you don't want to face backward-compatibility issues, I suggest that you first determine which version of which gem you want to get and then reinstall it with the -v version
. See an exemple below to make sure that the system won't get a new version of capistrano.
$ gem list | grep capistrano
capistrano (3.4.0, 3.2.1, 2.14.2)
$ sudo gem install capistrano -v 3.4.0
Update brew and upgrade your formulas
$ brew update
$ brew upgrade
You might also need to re-link some of them manually
$ brew link <formula>
I had the same error on Debian and all I had to do was:
sudo su
and then run the command again and it worked.
Although this question has been asked a while ago, it is still relevant as of today. This is not a trivial approach using script file params, but I already had some extreme use-cases that this way was most suited.
I came across this post to find out a better solution than I wrote a while ago, with hope to find maybe a native feature or something similar.
I will share my solution, up until a better one will be implemented. This works on most modern browsers, maybe even on older ones, didn't try.
All the solutions above, are based on the fact that it has to be injected with predefined and well marked SCRIPT tag and rely completely on the HTML implementation. But, what if the script is injected dynamically, or even worse, what if you are write a library, that will be used in a variety of websites?
In these and some other cases, all the above answers are not sufficient and even becoming too complicated.
First, let's try to understand what do we need to achieve here. All we need to do is to get the URL of the script itself, from there it's a piece of cake.
There is actually a nice trick to get the script URL from the script itself. One of the functionalities of the native Error
class, is the ability to provide a stack trace of the "problematic location", including the exact file trace to the last call. In order to achieve this, I will use the stack property of the Error instance, that once created, will give the full stack trace.
Here is how the magic works:
// The pattern to split each row in the stack trace string
const STACK_TRACE_SPLIT_PATTERN = /(?:Error)?\n(?:\s*at\s+)?/;
// For browsers, like Chrome, IE, Edge and more.
const STACK_TRACE_ROW_PATTERN1 = /^.+?\s\((.+?):\d+:\d+\)$/;
// For browsers, like Firefox, Safari, some variants of Chrome and maybe other browsers.
const STACK_TRACE_ROW_PATTERN2 = /^(?:.*?@)?(.*?):\d+(?::\d+)?$/;
const getFileParams = () => {
const stack = new Error().stack;
const row = stack.split(STACK_TRACE_SPLIT_PATTERN, 2)[1];
const [, url] = row.match(STACK_TRACE_ROW_PATTERN1) || row.match(STACK_TRACE_ROW_PATTERN2) || [];
if (!url) {
console.warn("Something went wrong. You should debug it and find out why.");
return;
}
try {
const urlObj = new URL(url);
return urlObj.searchParams; // This feature doesn't exists in IE, in this case you should use urlObj.search and handle the query parsing by yourself.
} catch (e) {
console.warn(`The URL '${url}' is not valid.`);
}
}
Now, in any case of script call, like in the OP case:
<script type="text/javascript" src="file.js?obj1=somevalue&obj2=someothervalue"></script>
In the file.js
script, you can now do:
const params = getFileParams();
console.log(params.get('obj2'));
// Prints: someothervalue
This will also work with RequireJS and other dynamically injected file scripts.
Some cases you might want to kill all the process running in a specific port. For example, if I am running a node app on 3000 port and I want to kill that and start a new one; then I found this command useful.
Find the process IDs running on TCP port 3000 and kill it
kill -9 `lsof -i TCP:3000 | awk '/LISTEN/{print $2}'`
you can download USBview and get all the information you need. Along with the list of devices it will also show you the configuration of each device.
Two things are happening here, and it's important to understand both.
As described in other answers, the Symbol#to_proc
method is being called.
But the reason to_proc
is being called on the symbol is because it's being passed to map
as a block argument. Placing &
in front of an argument in a method call causes it to be passed this way. This is true for any Ruby method, not just map
with symbols.
def some_method(*args, &block)
puts "args: #{args.inspect}"
puts "block: #{block.inspect}"
end
some_method(:whatever)
# args: [:whatever]
# block: nil
some_method(&:whatever)
# args: []
# block: #<Proc:0x007fd23d010da8>
some_method(&"whatever")
# TypeError: wrong argument type String (expected Proc)
# (String doesn't respond to #to_proc)
The Symbol
gets converted to a Proc
because it's passed in as a block. We can show this by trying to pass a proc to .map
without the ampersand:
arr = %w(apple banana)
reverse_upcase = proc { |i| i.reverse.upcase }
reverse_upcase.is_a?(Proc)
=> true
arr.map(reverse_upcase)
# ArgumentError: wrong number of arguments (1 for 0)
# (map expects 0 positional arguments and one block argument)
arr.map(&reverse_upcase)
=> ["ELPPA", "ANANAB"]
Even though it doesn't need to be converted, the method won't know how to use it because it expects a block argument. Passing it with &
gives .map
the block it expects.
Apologies for my previously mixed up answer.
Here is how to do:
myTreeView.SelectedNode = myTreeNode;
I have tested the code below and it works:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
treeView1.Nodes.Add("1", "1");
treeView1.Nodes.Add("2", "2");
treeView1.Nodes[0].Nodes.Add("1-1", "1-1");
TreeNode treeNode = treeView1.Nodes[0].Nodes.Add("1-2", "1-3");
treeView1.SelectedNode = treeNode;
MessageBox.Show(treeNode.IsSelected.ToString());
}
}
The answers by Richard and Jason are sort of in the right direction. However what you should be doing is computing the effective permissions for the user identity running your code. None of the examples above correctly account for group membership for example.
I'm pretty sure Keith Brown had some code to do this in his wiki version (offline at this time) of The .NET Developers Guide to Windows Security. This is also discussed in reasonable detail in his Programming Windows Security book.
Computing effective permissions is not for the faint hearted and your code to attempt creating a file and catching the security exception thrown is probably the path of least resistance.
A repo may seem corrupted if you mix different git
versions.
Local repositories touched by new git versions aren't backwards-compatible with old git versions. New git repos look corrupted to old git versions (in my case git 2.28 broke repo for git 2.11).
Updating old git version may solve the problem.
The standard equivalent of find -iname ... -exec mv -t dest {} +
for find
implementations that don't support -iname
or mv
implementations that don't support -t
is to use a shell to re-order the arguments:
find . -name '*.[cC][pP][pP]' -type f -exec sh -c '
exec mv "$@" /dest/dir/' sh {} +
By using -name '*.[cC][pP][pP]'
, we also avoid the reliance on the current locale to decide what's the uppercase version of c
or p
.
Note that +
, contrary to ;
is not special in any shell so doesn't need to be quoted (though quoting won't harm, except of course with shells like rc
that don't support \
as a quoting operator).
The trailing /
in /dest/dir/
is so that mv
fails with an error instead of renaming foo.cpp
to /dest/dir
in the case where only one cpp
file was found and /dest/dir
didn't exist or wasn't a directory (or symlink to directory).
Here is what I ended up using
$ipaddress = $(ipconfig | where {$_ -match 'IPv4.+\s(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})' } | out-null; $Matches[1])
which breaks down as
When you're using get()
you get a collection. In this case you need to iterate over it to get properties:
@foreach ($collection as $object)
{{ $object->title }}
@endforeach
Or you could just get one of objects by it's index:
{{ $collection[0]->title }}
Or get first object from collection:
{{ $collection->first() }}
When you're using find()
or first()
you get an object, so you can get properties with simple:
{{ $object->title }}
Go to Preferences
> User Settings
. (Alternatively, Ctrl + , / Cmd + , on macOS)
Then you can type inside the JSON object any settings you want to override. User settings are per user. You can also configure workspace settings, which are for the project that you are currently working on.
Here's an example:
// Controls the font family.
"editor.fontFamily": "Consolas",
// Controls the font size.
"editor.fontSize": 13

Be careful with doing this manually.
In fact I would advise not doing this at all.
In reality we are talking about the line termination sequence LTS that is specific to platform.
If you open a file in text mode (ie not binary) then the streams will convert the "\n" into the correct LTS for your platform. Then convert the LTS back to "\n" when you read the file.
As a result if you print "\r\n" to a windows file you will get the sequence "\r\r\n" in the physical file (have a look with a hex editor).
Of course this is real pain when it comes to transferring files between platforms.
Now if you are writing to a network stream then I would do this manually (as most network protocols call this out specifically). But I would make sure the stream is not doing any interpretation (so binary mode were appropriate).
The short answer here is the serial ID is computed via a hash if you don't specify it. (Static members are not inherited--they are static, there's only (1) and it belongs to the class).
http://docs.oracle.com/javase/6/docs/platform/serialization/spec/class.html
The getSerialVersionUID method returns the serialVersionUID of this class. Refer to Section 4.6, "Stream Unique Identifiers." If not specified by the class, the value returned is a hash computed from the class's name, interfaces, methods, and fields using the Secure Hash Algorithm (SHA) as defined by the National Institute of Standards.
If you alter a class or its hierarchy your hash will be different. This is a good thing. Your objects are different now that they have different members. As such, if you read it back in from its serialized form it is in fact a different object--thus the exception.
The long answer is the serialization is extremely useful, but probably shouldn't be used for persistence unless there's no other way to do it. Its a dangerous path specifically because of what you're experiencing. You should consider a database, XML, a file format and probably a JPA or other persistence structure for a pure Java project.
def nested1(num1):
print "nested1 has",num1
def nested2(num2):
print "nested2 has",num2,"and it can reach to",num1
return num1+num2 #num1 referenced for reading here
return nested2
Gives:
In [17]: my_func=nested1(8)
nested1 has 8
In [21]: my_func(5)
nested2 has 5 and it can reach to 8
Out[21]: 13

It is debatable as to whether you should use String or use Char[] for this purpose because both have their advantages and disadvantages. It depends on what the user needs.
Since Strings in Java are immutable, whenever some tries to manipulate your string it creates a new Object and the existing String remains unaffected. This could be seen as an advantage for storing a password as a String, but the object remains in memory even after use. So if anyone somehow got the memory location of the object, that person can easily trace your password stored at that location.
Char[] is mutable, but it has the advantage that after its usage the programmer can explicitly clean the array or override values. So when it's done being used it is cleaned and no one could ever know about the information you had stored.
Based on the above circumstances, one can get an idea whether to go with String or to go with Char[] for their requirements.
If you could use something other than 'awk' , then try this instead
echo '1540 "A B"' | cut -d' ' -f2-
-d is a delimiter, -f is the field to cut and with -f2- we intend to cut the 2nd field until end.

The maximal length of the target column is shorter than the value you try to insert.
Rightclick the table in SQL manager and go to 'Design' to visualize your table structure and column definitions.
Edit:
Try to set a length on your nvarchar inserts thats the same or shorter than whats defined in your table.

Here is the latest documentation:
A lot of the answers here were written prior to Roslyn (the open-source .NET C# and VB compilers) moving to .NET 4.6. So they won't help you if your project targets, say, 4.5.2 as mine did (inherited and can't be changed).
But you can grab a previous version of Roslyn from https://www.nuget.org/packages/Microsoft.Net.Compilers and install that instead of the latest version. I used 1.3.2. (I tried 2.0.1 - which appears to be the last version that runs on .NET 4.5 - but I couldn't get it to compile*.) Run this from the Package Manager console in VS 2013:
PM> Install-Package Microsoft.Net.Compilers -Version 1.3.2
Then restart Visual Studio. I had a couple of problems initially; you need to set the C# version back to default (C#6.0 doesn't appear in the version list but seems to have been made the default), then clean, save, restart VS and recompile.
Interestingly, I didn't have any IntelliSense errors due to the C#6.0 features used in the code (which were the reason for wanting C#6.0 in the first place).
* version 2.0.1 threw error The "Microsoft.CodeAnalysis.BuildTasks.Csc task could not be loaded from the assembly Microsoft.Build.Tasks.CodeAnalysis.dll. Could not load file or assembly 'Microsoft.Build.Utilities.Core, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. Confirm that the declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask.
UPDATE One thing I've noticed since posting this answer is that if you change any code during debug ("Edit and Continue"), you'll like find that your C#6.0 code will suddenly show as errors in what seems to revert to a pre-C#6.0 environment. This requires a restart of your debug session. VERY annoying especially for web applications.

jQuery makes it easy to set any attributes for an element - just use the .attr()
method:
$(document).ready(function() {
$("input").attr({
"max" : 10, // substitute your own
"min" : 2 // values (or variables) here
});
});
The document ready handler is not required if your script block appears after the element(s) you want to manipulate.
Using a selector of "input"
will set the attributes for all inputs though, so really you should have some way to identify the input in question. If you gave it an id you could say:
$("#idHere").attr(...
...or with a class:
$(".classHere").attr(...
I would be tempted to use grepl
, which should give all the lines with matches and can be generalised for arbitrary strings.

[Edit] However, as pointed out in the comments, this will capture much more than the string 1578 (e.g. it also matches for 21578 etc) and thus should be used only if you are certain that you the length of the values you are searching will not be larger than the four characters or digits shown here.

For windows users this Stack Overflow question and top answer is quite useful on how to set environement variables via the command line
Here's what I ended up using.
I'm very new to AngularJS, so would love to see better / alternative solutions.
angular.module('formComponents', [])
.directive('formInput', function() {
return {
restrict: 'E',
scope: {},
link: function(scope, element, attrs)
{
var type = attrs.type || 'text';
var required = attrs.hasOwnProperty('required') ? "required='required'" : "";
var htmlText = '<div class="control-group">' +
'<label class="control-label" for="' + attrs.formId + '">' + attrs.label + '</label>' +
'<div class="controls">' +
'<input type="' + type + '" class="input-xlarge" id="' + attrs.formId + '" name="' + attrs.formId + '" ' + required + '>' +
'</div>' +
'</div>';
element.html(htmlText);
}
}
})
Example usage:
<form-input label="Application Name" form-id="appName" required/></form-input>
<form-input type="email" label="Email address" form-id="emailAddress" required/></form-input>
<form-input type="password" label="Password" form-id="password" /></form-input>
For future reference:
yyyy => 4 digit year
MM => 2 digit month (you must type MM in ALL CAPS)
dd => 2 digit "day of the month"
HH => 2-digit "hour in day" (0 to 23)
mm => 2-digit minute (you must type mm in lowercase)
ss => 2-digit seconds
SSS => milliseconds
So "yyyy-MM-dd HH:mm:ss" returns "2018-01-05 09:49:32"
But "MMM dd, yyyy hh:mm a" returns "Jan 05, 2018 09:49 am"
The so-called examples at https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html show only output. They do not tell you what formats to use!
You can use an array in the select() to define more columns and you can use the DB::raw() there with aliasing it to followers. Should look like this:
$query = DB::table('category_issue')
->select(array('issues.*', DB::raw('COUNT(issue_subscriptions.issue_id) as followers')))
->where('category_id', '=', 1)
->join('issues', 'category_issue.issue_id', '=', 'issues.id')
->left_join('issue_subscriptions', 'issues.id', '=', 'issue_subscriptions.issue_id')
->group_by('issues.id')
->order_by('followers', 'desc')
->get();
You need to remember that CSRF token is stored in the session, so this problem can also occur due to invalid session handling. If you're working on the localhost, check e.g. if session cookie domain is set correctly (in PHP it should be empty when on localhost).
split
is deprecated since it is part of the family of functions which make use of POSIX regular expressions; that entire family is deprecated in favour of the PCRE (preg_*
) functions.
If you do not need the regular expression functionality, then explode
is a very good choice (and would have been recommended over split
even if that were not deprecated), if on the other hand you do need to use regular expressions then the PCRE alternate is simply preg_split
.
This question is old, but we live in a world of ES6 and functional JavaScript, so let's see how we can improve.
Because promises execute immediately, we can't just create an array of promises, they would all fire off in parallel.
Instead, we need to create an array of functions that returns a promise. Each function will then be executed sequentially, which then starts the promise inside.
We can solve this a few ways, but my favorite way is to use reduce
.
It gets a little tricky using reduce
in combination with promises, so I have broken down the one liner into some smaller digestible bites below.
The essence of this function is to use reduce
starting with an initial value of Promise.resolve([])
, or a promise containing an empty array.
This promise will then be passed into the reduce
method as promise
. This is the key to chaining each promise together sequentially. The next promise to execute is func
and when the then
fires, the results are concatenated and that promise is then returned, executing the reduce
cycle with the next promise function.
Once all promises have executed, the returned promise will contain an array of all the results of each promise.
ES6 Example (one liner)
/*
* serial executes Promises sequentially.
* @param {funcs} An array of funcs that return promises.
* @example
* const urls = ['/url1', '/url2', '/url3']
* serial(urls.map(url => () => $.ajax(url)))
* .then(console.log.bind(console))
*/
const serial = funcs =>
funcs.reduce((promise, func) =>
promise.then(result => func().then(Array.prototype.concat.bind(result))), Promise.resolve([]))
ES6 Example (broken down)
// broken down to for easier understanding
const concat = list => Array.prototype.concat.bind(list)
const promiseConcat = f => x => f().then(concat(x))
const promiseReduce = (acc, x) => acc.then(promiseConcat(x))
/*
* serial executes Promises sequentially.
* @param {funcs} An array of funcs that return promises.
* @example
* const urls = ['/url1', '/url2', '/url3']
* serial(urls.map(url => () => $.ajax(url)))
* .then(console.log.bind(console))
*/
const serial = funcs => funcs.reduce(promiseReduce, Promise.resolve([]))
Usage:
// first take your work
const urls = ['/url1', '/url2', '/url3', '/url4']
// next convert each item to a function that returns a promise
const funcs = urls.map(url => () => $.ajax(url))
// execute them serially
serial(funcs)
.then(console.log.bind(console))
You need to stop the submission if an error occured:
HTML
<form name ="myform" onsubmit="return validation();">
JS
if (document.myform.username.value == "") {
document.getElementById('errors').innerHTML="*Please enter a username*";
return false;
}
Also add the following event to deal with pasting into the textarea:
...
txts[i].onkeyup = function() {
...
}
txts[i].paste = function() {
var len = parseInt(this.getAttribute("maxlength"), 10);
if (this.value.length + window.clipboardData.getData("Text").length > len) {
alert('Maximum length exceeded: ' + len);
this.value = this.value.substr(0, len);
return false;
}
}
...
None of the other answers helped me. Here's what worked for me. I'm using the tutorial-1 sample from opencv but I will be doing using the NDK in my project so I'm using the gradle-experimental plugin which has a different structure than the gradle plugin.
Android studio should be installed, the Android NDK should be installed via the Android SDK Manager, and the OpenCV Android SDK should be downloaded and unzipped.
This is in chunks of bash script to keep it compact but complete. It's also all on the command line because on of the big problems I had was that in-IDE instructions were obsolete as the IDE evolved.
First set the location of the root directory of the OpenCV SDK.
export OPENCV_SDK=/home/user/wip/OpenCV-2.4.11-android-sdk
cd $OPENCV_SDK
Create your gradle build files...
First the OpenCV library
cat > $OPENCV_SDK/sdk/java/build.gradle <<'==='
apply plugin: 'com.android.model.library'
model {
android {
compileSdkVersion = 23
buildToolsVersion = "23.0.2"
defaultConfig.with {
minSdkVersion.apiLevel = 8
targetSdkVersion.apiLevel = 23
}
}
android.buildTypes {
release {
minifyEnabled = false
}
debug{
minifyEnabled = false
}
}
android.sources {
main.manifest.source.srcDirs += "."
main.res.source.srcDirs += "res"
main.aidl.source.srcDirs += "src"
main.java.source.srcDirs += "src"
}
}
===
Then tell the tutorial sample what to label the library as and where to find it.
cat > $OPENCV_SDK/samples/tutorial-1-camerapreview/settings.gradle <<'==='
include ':openCVLibrary2411'
project(':openCVLibrary2411').projectDir = new File('../../sdk/java')
===
Create the build file for the tutorial.
cat > $OPENCV_SDK/samples/tutorial-1-camerapreview/build.gradle <<'==='
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle-experimental:0.2.1'
}
}
allprojects {

}
}
apply plugin: 'com.android.model.application'
model {
android {
compileSdkVersion = 23
buildToolsVersion = "23.0.2"
defaultConfig.with {
applicationId = "org.opencv.samples.tutorial1"
minSdkVersion.apiLevel = 8
targetSdkVersion.apiLevel = 23
}
}
android.sources {

main.aidl.source.srcDirs += "src"
main.java.source.srcDirs += "src"
}
android.buildTypes {
release {
minifyEnabled = false
proguardFiles += file('proguard-rules.pro')
}
debug {
minifyEnabled = false
}
}
}
dependencies {
compile project(':openCVLibrary2411')
}
===
Your build tools version needs to be set correctly. Here's an easy way to see what you have installed. (You can install other versions via the Android SDK Manager). Change buildToolsVersion if you don't have 23.0.2.
echo "Your buildToolsVersion is one of: "
ls $ANDROID_HOME/build-tools
Change the environment variable on the first line to your version number
REP=23.0.2 #CHANGE ME
sed -i.bak s/23\.0\.2/${REP}/g $OPENCV_SDK/sdk/java/build.gradle
sed -i.bak s/23\.0\.2/${REP}/g $OPENCV_SDK/samples/tutorial-1-camerapreview/build.gradle
Finally, set up the correct gradle wrapper. Gradle needs a clean directory to do this.
pushd $(mktemp -d)
gradle wrapper --gradle-version 2.5
mv -f gradle* $OPENCV_SDK/samples/tutorial-1-camerapreview
popd
You should now be all set. You can now browse to this directory with Android Studio and open up the project.
Build the tutoral on the command line with the following command:
./gradlew assembleDebug
It should build your apk, putting it in ./build/outputs/apk
the quick fix is to assign your variable to null at the top of your code
$user_location = null;
Here are my "answers" (trying to be unique here, I don't actually recommend either for this particular case :-)
Using ord() and the special a <= b <= c
form:
//starts_with_digit = ord('0') <= ord(mystring[0]) <= ord('9')
//I was thinking too much in C. Strings are perfectly comparable.
starts_with_digit = '0' <= mystring[0] <= '9'
(This a <= b <= c
, like a < b < c
, is a special Python construct and it's kind of neat: compare 1 < 2 < 3
(true) and 1 < 3 < 2
(false) and (1 < 3) < 2
(true). This isn't how it works in most other languages.)
Using a regular expression:
import re
//starts_with_digit = re.match(r"^\d", mystring) is not None
//re.match is already anchored
starts_with_digit = re.match(r"\d", mystring) is not None
I find this type of approach works for me:
Product ProductDetail Country ========= ================== ========= ProductId ProductDetailId CountryId - etc - ProductId CountryName CountryId Language ProductName - etc - ProductDescription - etc -
The ProductDetail table holds all the translations (for product name, description etc..) in the languages you want to support. Depending on your app's requirements, you may wish to break the Country table down to use regional languages too.

This is just a sample code, but it may help you get on your way:
Public Sub testIt()
Workbooks("Workbook2").Activate
ActiveWorkbook.Sheets("Sheet2").Activate
ActiveSheet.Range("B3").Select
ActiveCell.EntireRow.Insert
End Sub
I am assuming that you can open the book (called Workbook2
in the example).
I think (but I'm not sure) you can squash all this in a single line of code:
Workbooks("Workbook2").Sheets("Sheet2").Range("B3").EntireRow.Insert
This way you won't need to activate the workbook (or sheet or cell)... Obviously, the book has to be open.

Good work on server with 256MB Memory.
It indicates that the servlet won't be started until a request tries to access it.
If load-on-startup is greater than or equal to zero then when the container starts it will start that servlet in ascending order of the load on startup value you put there (ie 0, 1 then 2 then 5 then 10 and so on).
Do you just mean spaces or all whitespace?
For just spaces, use str_replace:
$string = str_replace(' ', '', $string);
For all whitespace (including tabs and line ends), use preg_replace:
$string = preg_replace('/\s+/', '', $string);
(From here).
I found netlimiter4 to be the best solution for throttling data to emulators. It provides for granular control through a decent gui and gives you graphical feedback on the data throughput to each process. Currently in a free beta. screenshot

There are apps available on the play store to throttle to actual devices but they require root(I cant provide any advice as to how well they work, if at at all - YMMV.)
search for bradybound on the play store, I can't post more than one link..
This happens due to caching.
When you run, php artisan config:cache, it will cache the configuration files. Whenever things get change, you need to keep running it to update the cache files. But, it won't cache if you never run that command.
This is OK for production, since config don't change that often. But during staging or dev, you can just disable caching by clearing the cache and don't run the cache command
So, just run php artisan config:clear, and don't run the command previously to avoid caching.

You can try like below:
app.directive("directive_name", function(){
return {
restrict:'E',
transclude:true,
template:'<div class="title"><h2>{{title}}</h3></div>',
scope:{
accept:"="
},
replace:true
};
})
it sets up a two-way binding between the value of the 'accept' attribute and the parent scope.
And also you can set two way data binding with property: '='
For example, if you want both key and value bound to the local scope you would do:
scope:{
key:'=',
value:'='
},
