I had the same problem:
As I was reluctant to give 0777 to my php directory, I create a tmp directory with rights 0777, where I create the files I need to write to.
My php directory continue to be protected. If somebody hackes the tmp directory, the site continue to work as usual.
Fiddler v4.5.1.0 will allow you to go to replace "localhost" with "localhost.fiddler", and present localhost as the host name for the receiving server running on your machine.
This avoids "host not recognised" errors when connecting to WCF services with the built in web server that visual studio uses.
i.e. Instead of
http://localhost:51900/service.wcf
you can use http://localhost.fiddler:51900/service.wcf

File uploads can not be done this way, no matter how you break it down. If you want to do an ajax/async upload, I would suggest looking into something like Uploadify, or Valums
There are various methods available in Rust to concatenate strings
concat!()
):fn main() {
println!("{}", concat!("a", "b"))
}
The output of the above code is :
ab
push_str()
and +
operator):fn main() {
let mut _a = "a".to_string();
let _b = "b".to_string();
let _c = "c".to_string();
_a.push_str(&_b);
println!("{}", _a);
println!("{}", _a + &_c);
}
The output of the above code is:
ab
abc
Using format!()
):fn main() {
let mut _a = "a".to_string();
let _b = "b".to_string();
let _c = format!("{}{}", _a, _b);
println!("{}", _c);
}
The output of the above code is :
ab
Check it out and experiment with Rust playground.
Just create a symlink in your src folder for the namespace pointing to the folder containing your classes...
ln -s ../src/AppName ./src/AppName
Your autoload in composer will look the same...
"autoload": {
"psr-0": {"AppName": "src/"}
}
And your AppName namespaced classes will start a directory up from your current working directory in a src
folder now... that should work.
If you want a list of lists:
>>> [list(t) for t in zip(*l)]
[[1, 3, 8], [2, 4, 9]]
If a list of tuples is OK:
>>> zip(*l)
[(1, 3, 8), (2, 4, 9)]
A table can easily be placed with the following parameters:
h
Place the float here, i.e., approximately at the same point it occurs in the source text (however, not exactly at the spot)t
Position at the top of the page.b
Position at the bottom of the page.p
Put on a special page for floats only.!
Override internal parameters LaTeX uses for determining "good" float positions.H
Places the float at precisely the location in the LATEX code. Requires the float package. This is somewhat equivalent to h!
.If you want to make use of H
(or h!
) for an exact positioning, make sure you got the float
package correctly set up in the preamble:
\usepackage{float}
\restylefloat{table}
If you want to place the table at the same page, either at the exact place or at least at the top of the page (what fits best for the latex engine), use the parameters h
and t
like this:
\begin{table}[ht]
table content ...
\end{table}

Doing this with POSIX is tricky:
POSIX Sed does not support \r
or \15
. Even if it did, the in place
option -i
is not POSIX
POSIX Awk does support \r
and \15
, however the -i inplace
option
is not POSIX
d2u and dos2unix are not POSIX utilities, but ex is
POSIX ex does not support \r
, \15
, \n
or \12
To remove carriage returns:
awk 'BEGIN{RS="^$";ORS="";getline;gsub("\r","");print>ARGV[1]}' file
To add carriage returns:
awk 'BEGIN{RS="^$";ORS="";getline;gsub("\n","\r&");print>ARGV[1]}' file
In Oracle, you could do this:

No need to do your own implementation. I can recommend using geolocationmarker
from google-maps-utility-library-v3.
Draw the include below to make it compile:
#include <ChuckNorris>

You can use the following. They all wrap the window
object into a jQuery object.
$(window).load(function () {
topInViewport($("#mydivname"))
});
$(window).resize(function () {
topInViewport($("#mydivname"))
});
$(window).scroll(function () {
topInViewport($("#mydivname"))
});
Or bind to them all using on
:
$(window).on("load resize scroll",function(e){
topInViewport($("#mydivname"))
});
#include <windows.h>
using namespace std;
// The directory path returned by native GetCurrentDirectory() no end backslash
string getCurrentDirectoryOnWindows()
{
const unsigned long maxDir = 260;
char currentDir[maxDir];
GetCurrentDirectory(maxDir, currentDir);
return string(currentDir);
}
Check this answer: Set CORS header in Tomcat
Note that you need Tomcat 7.0.41 or higher.
To know where the current instance of Tomcat is located try this:
System.out.println(System.getProperty("catalina.base"));
You'll see the path in the console view.
Then look for /conf/web.xml on that folder, open it and add the lines of the above link.
This is the correct way:

You're after the zip function.
Taken directly from the question: How to merge lists into a list of tuples in Python?
>>> list_a = [1, 2, 3, 4]
>>> list_b = [5, 6, 7, 8]
>>> zip(list_a,list_b)
[(1, 5), (2, 6), (3, 7), (4, 8)]
Useful Utils methods as below for manage Time in GMT with DST Savings:
public static Date convertToGmt(Date date) {
TimeZone tz = TimeZone.getDefault();
Date ret = new Date(date.getTime() - tz.getRawOffset());
// if we are now in DST, back off by the delta. Note that we are checking the GMT date, this is the KEY.
if (tz.inDaylightTime(ret)) {
Date dstDate = new Date(ret.getTime() - tz.getDSTSavings());
// check to make sure we have not crossed back into standard time
// this happens when we are on the cusp of DST (7pm the day before the change for PDT)
if (tz.inDaylightTime(dstDate)) {
ret = dstDate;
}
}
return ret;
}
public static Date convertFromGmt(Date date) {
TimeZone tz = TimeZone.getDefault();
Date ret = new Date(date.getTime() + tz.getRawOffset());
// if we are now in DST, back off by the delta. Note that we are checking the GMT date, this is the KEY.
if (tz.inDaylightTime(ret)) {
Date dstDate = new Date(ret.getTime() + tz.getDSTSavings());
// check to make sure we have not crossed back into standard time
// this happens when we are on the cusp of DST (7pm the day before the change for PDT)
if (tz.inDaylightTime(dstDate)) {
ret = dstDate;
}
}
return ret;
}
Strings can be joined together using the concatenation operator ".."
this is the same for variables I think
from r cookbook, where bp is your ggplot:
Remove legend for a particular aesthetic (fill):
bp + guides(fill=FALSE)
It can also be done when specifying the scale:
bp + scale_fill_discrete(guide=FALSE)
This removes all legends:
bp + theme(legend.position="none")
If your string contains non-ASCII characters - it's better to do it this way:
s.toUtf8().data()
(or s->toUtf8().data()
)
Try getting the “left part” of the url, like this:
string domainName = HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority);
This will give you either http://localhost:5858
or https://www.somedomainname.com
whether you're on local or production. If you want to drop the www
part, you should configure IIS to do so, but that's another topic.
Do note that the resulting URL will not have a trailing slash.
Converting the String to JsonNode using ObjectMapper object :
ObjectMapper mapper = new ObjectMapper();
// For text string
JsonNode = mapper.readValue(mapper.writeValueAsString("Text-string"), JsonNode.class)
// For Array String
JsonNode = mapper.readValue("[\"Text-Array\"]"), JsonNode.class)
// For Json String
String json = "{\"id\" : \"1\"}";
ObjectMapper mapper = new ObjectMapper();
JsonFactory factory = mapper.getFactory();
JsonParser jsonParser = factory.createParser(json);
JsonNode node = mapper.readTree(jsonParser);
I was using on wrong way an coordinator layout attribute, I removed that and it works. Check your layout
app:layout_constraintVertical_bias="parent"
That should be a numeric value not literal :/ tiny mistake
One should not recommend this as a general solution, but for one-off deletion of rows in a database that is not in production or in active use, you may be able to temporarily disable triggers on the tables in question.
In my case, I'm in development mode and have a couple of tables that reference one another via foreign keys. Thus, deleting their contents isn't quite as simple as removing all of the rows from one table before the other. So, for me, it worked fine to delete their contents as follows:
ALTER TABLE table1 DISABLE TRIGGER ALL;
ALTER TABLE table2 DISABLE TRIGGER ALL;
DELETE FROM table1;
DELETE FROM table2;
ALTER TABLE table1 ENABLE TRIGGER ALL;
ALTER TABLE table2 ENABLE TRIGGER ALL;
You should be able to add WHERE clauses as desired, of course with care to avoid undermining the integrity of the database.
There's some good, related discussion at http://www.openscope.net/2012/08/23/subverting-foreign-key-constraints-in-postgres-or-mysql/
This could be more helpfull....
$("element").prop("id", "modifiedId");
//for boolean
$("element").prop("disabled", true);
//also you can remove attribute
$('#someid').removeProp('disabled');
Use Hosts Commander. It's simple and powerful. Translated description (from russian) here.
hosts add another.dev 192.168.1.1 # Remote host
hosts add test.local # 127.0.0.1 used by default
hosts set myhost.dev # new comment
hosts rem *.local
hosts enable local*
hosts disable localhost
...and many others...
Usage:
hosts - run hosts command interpreter
hosts <command> <params> - execute hosts command
Commands:
add <host> <aliases> <addr> # <comment> - add new host
set <host|mask> <addr> # <comment> - set ip and comment for host
rem <host|mask> - remove host
on <host|mask> - enable host
off <host|mask> - disable host
view [all] <mask> - display enabled and visible, or all hosts
hide <host|mask> - hide host from 'hosts view'
show <host|mask> - show host in 'hosts view'
print - display raw hosts file
format - format host rows
clean - format and remove all comments
rollback - rollback last operation
backup - backup hosts file
restore - restore hosts file from backup
recreate - empty hosts file
open - open hosts file in notepad
Not with plain HTML I'm afraid.
You could use some jQuery to do this though:
$(function(){
var $select = $(".1-100");
for (i=1;i<=100;i++){
$select.append($('<option></option>').val(i).html(i))
}
});?
You can download jQuery here
Sure you can simply use two sliders overlaying each other and add a bit of javascript (actually not more than 5 lines) that the selectors are not exceeding the min/max values (like in @Garys) solution.
Attached you'll find a short snippet adapted from a current project including some CSS3 styling to show what you can do (webkit only). I also added some labels to display the selected values.
It uses JQuery but a vanillajs version is no magic though.
@Update: The code below was just a proof of concept. Due to many requests I've added a possible solution for Mozilla Firefox (without changing the original code). You may want to refractor the code below before using it.
(function() {
function addSeparator(nStr) {
nStr += '';
var x = nStr.split('.');
var x1 = x[0];
var x2 = x.length > 1 ? '.' + x[1] : '';
var rgx = /(\d+)(\d{3})/;
while (rgx.test(x1)) {
x1 = x1.replace(rgx, '$1' + '.' + '$2');
}
return x1 + x2;
}

Amit, I have used one way to achieve this with less coding and more efficient way.
but it uses Linq.
I posted it here because maybe the answer helps other SO.
Below DAL code converts datatable object to List of YourViewModel and it's easy to understand.
public static class DAL
{
public static string connectionString = ConfigurationManager.ConnectionStrings["YourWebConfigConnection"].ConnectionString;
// function that creates a list of an object from the given data table
public static List<T> CreateListFromTable<T>(DataTable tbl) where T : new()
{
// define return list
List<T> lst = new List<T>();
// go through each row
foreach (DataRow r in tbl.Rows)
{
// add to the list
lst.Add(CreateItemFromRow<T>(r));
}
// return the list
return lst;
}
// function that creates an object from the given data row
public static T CreateItemFromRow<T>(DataRow row) where T : new()
{
// create a new object
T item = new T();
// set the item
SetItemFromRow(item, row);
// return
return item;
}
public static void SetItemFromRow<T>(T item, DataRow row) where T : new()
{
// go through each column
foreach (DataColumn c in row.Table.Columns)
{
// find the property for the column
PropertyInfo p = item.GetType().GetProperty(c.ColumnName);
// if exists, set the value
if (p != null && row[c] != DBNull.Value)
{
p.SetValue(item, row[c], null);
}
}
}
//call stored procedure to get data.
public static DataSet GetRecordWithExtendedTimeOut(string SPName, params SqlParameter[] SqlPrms)
{
DataSet ds = new DataSet();
SqlCommand cmd = new SqlCommand();
SqlDataAdapter da = new SqlDataAdapter();
SqlConnection con = new SqlConnection(connectionString);
try
{
cmd = new SqlCommand(SPName, con);
cmd.Parameters.AddRange(SqlPrms);
cmd.CommandTimeout = 240;
cmd.CommandType = CommandType.StoredProcedure;
da.SelectCommand = cmd;
da.Fill(ds);
}
catch (Exception ex)
{
return ex;
}
return ds;
}
}
Now, The way to pass and call method is below.
DataSet ds = DAL.GetRecordWithExtendedTimeOut("ProcedureName");
List<YourViewModel> model = new List<YourViewModel>();
if (ds != null)
{
//Pass datatable from dataset to our DAL Method.
model = DAL.CreateListFromTable<YourViewModel>(ds.Tables[0]);
}
Till the date, for many of my applications, I found this as the best structure to get data.
Another option is to put the ListItems into an array and sort.
int i = 0;
string[] array = new string[items.Count];
foreach (ListItem li in dropdownlist.items)
{
array[i] = li.ToString();
i++;
}
Array.Sort(array);
dropdownlist.DataSource = array;
dropdownlist.DataBind();

UPDATED ANSWER for iOS 13 and scene delegate:
make sure in your info.plist file you go into Application Scene Manifest -> Scene Configuration -> Application Session Role -> Item 0 and delete the reference to the main storyboard there as well. Otherwise you'll get the same warning about failing to instantiate from storyboard.
Also, move the code from the app delegate to the scene delegate method scene(_:willConnectTo:options:), since this is where life cycle events are handled now.
You don't need JDK
to run Java based programs. JDK
is for development which stands for Java Development Kit
.
You need JRE
which should be there in Mac.
Try: java -jar Myjar_file.jar
EDIT: According to this article, for Mac OS 10
The Java runtime is no longer installed automatically as part of the OS installation.
Then, you need to install JRE to your machine.
Assuming you were in your own topic branch. If you want to merge the last 2 commits into one and look like a hero, branch off the commit just before you made the last two commits (specified with the relative commit name HEAD~2).
git checkout -b temp_branch HEAD~2
Then squash commit the other branch in this new branch:
git merge branch_with_two_commits --squash
That will bring in the changes but not commit them. So just commit them and you're done.
git commit -m "my message"
Now you can merge this new topic branch back into your main branch.
No where in your question do you mention time zone. What time zone is implied that input string? What time zone do you want for your output? And, UTC is a time zone (or lack thereof depending on your mindset) not a string format.
Your input string is in ISO 8601 format, except that it lacks an offset from UTC.
Here is some example code in Joda-Time 2.3 to show you how to handle time zones. Joda-Time has built-in default formatters for parsing and generating String representations of date-time values.
String input = "2013-10-22T01:37:56";
DateTime dateTimeUtc = new DateTime( input, DateTimeZone.UTC );
DateTime dateTimeMontréal = dateTimeUtc.withZone( DateTimeZone.forID( "America/Montreal" );
String output = dateTimeMontréal.toString();
As for generating string representations in other formats, search StackOverflow for "Joda format".
After Python 3.5 you can also use:
import subprocess
f = open('test.txt', 'w')
process = subprocess.run(['ls', '-la'], stdout=subprocess.PIPE, universal_newlines=True)
f.write(process.stdout)
f.close()
The execution of the command is blocking and the output will be in process.stdout.

I found this on google, tested in Excel 2003 & it works for me:
=IF(COUNTIF(A1,"* *"),RIGHT(A1,LEN(A1)-LOOKUP(LEN(A1),FIND(" ",A1,ROW(INDEX($A:$A,1,1):INDEX($A:$A,LEN(A1),1))))),A1)
[edit] I don't have enough rep to comment, so this seems the best place...BradC's answer also doesn't work with trailing spaces or empty cells...
[2nd edit] actually, it doesn't work for single words either...
This very annoying error so what I did: Under Windows:
Edit system environment variables - > Edit Variables -> New
then fill
MAVEN_OPTS
-Xms512m -Xmx2048m -XX:MaxPermSize=512m
Then restart the console and run the maven build again. No more Maven space/perm size problems.
You can use blank.gif (1px transparent image) as target in your tag
<input type="image" src="img/blank.gif" class="button">
and then style background in css:
.button {border:0;background:transparent url("../img/button.png") no-repeat 0 0;}
.button:hover {background:transparent url("../img/button-hover.png") no-repeat 0 0;}
As of Java 11 one can use Pattern#asMatchPredicate
which returns Predicate<String>
.
String string = "stores%store%product";
String regex = "stores.*store.*product.*";
Predicate<String> matchesRegex = Pattern.compile(regex).asMatchPredicate();
boolean match = matchesRegex.test(string); // true
The method enables chaining with other String predicates, which is the main advantage of this method as long as the Predicate
offers and
, or
and negate
methods.
String string = "stores$store$product";
String regex = "stores.*store.*product.*";
Predicate<String> matchesRegex = Pattern.compile(regex).asMatchPredicate();
Predicate<String> hasLength = s -> s.length() > 20;
boolean match = hasLength.and(matchesRegex).test(string); // false
For Logging your request and response you need an interceptor and also for setting the header you need an interceptor, Here's the solution for adding both the interceptor at once using retrofit 2.1
public OkHttpClient getHeader(final String authorizationValue ) {
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient okClient = new OkHttpClient.Builder()
.addInterceptor(interceptor)
.addNetworkInterceptor(
new Interceptor() {
@Override
public Response intercept(Interceptor.Chain chain) throws IOException {
Request request = null;
if (authorizationValue != null) {
Log.d("--Authorization-- ", authorizationValue);
Request original = chain.request();
// Request customization: add request headers
Request.Builder requestBuilder = original.newBuilder()
.addHeader("Authorization", authorizationValue);
request = requestBuilder.build();
}
return chain.proceed(request);
}
})
.build();
return okClient;
}
Now in your retrofit object add this header in the client
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(url)
.client(getHeader(authorizationValue))
.addConverterFactory(GsonConverterFactory.create())
.build();
if we are using JpaRepository then it will internally created the queries.
Sample
findByLastnameAndFirstname(String lastname,String firstname)
findByLastnameOrFirstname(String lastname,String firstname)
findByStartDateBetween(Date date1,Date2)
findById(int id)
Note
if suppose we need complex queries then we need to write manual queries like
@Query("SELECT salesOrder FROM SalesOrder salesOrder WHERE salesOrder.clientId=:clientId AND salesOrder.driver_username=:driver_username AND salesOrder.date>=:fdate AND salesOrder.date<=:tdate ")
@Transactional(readOnly=true)
List<SalesOrder> findAllSalesByDriver(@Param("clientId")Integer clientId, @Param("driver_username")String driver_username, @Param("fdate") Date fDate, @Param("tdate") Date tdate);
When a CSS property shows as struck-through, it means that the crossed-out style was applied, but then overridden by a more specific selector, a more local rule, or by a later property within the same rule.
(Special cases: a style will also be shown as struck-through if a style exists in an matching rule but is commented out, or if you've manually disabled it by unchecking it within the Chrome developer tools. It will also show as crossed out, but with an error icon, if the style has a syntax error.)
For example, if a background color was applied to all div
s, but a different background color was applied to div
s with a certain id, the first color will show up but will be crossed out, as the second color has replaced it (in the property list for the div
with that id).
{=FIND("cell I want to search","list of words I want to search for")}
{=SUM(FIND($A$1:$A$100&"|";A3))}
this ensures spreadsheet will compare strings like "cellvlaue|" againts "pattern1|", "pattern2|" etc. which sorts out conflicts like pattern1="newly added", pattern2="added" (sum of all cells matching "added" would be too high, including the target values for cells matching "newly added", which would be a logical error)You can always check this maintained list to timezones
Use following property same as table and its fully dynamic:

display: table;_x000D_
table-layout: fixed; /* optional, for equal spacing */_x000D_
border-collapse: collapse;_x000D_
}_x000D_
li {_x000D_
display: table-cell;_x000D_
text-align: center;_x000D_
border: 1px solid pink;_x000D_
vertical-align: middle;_x000D_
}
_x000D_
<ul>_x000D_
<li>foo<br>foo</li>_x000D_
<li>barbarbarbarbar</li>_x000D_
<li>baz klxjgkldjklg </li>_x000D_

May be its solve your issue.
Exceptions are a good way to handle unexpected events in your application flow. RuntimeException are unchecked by the Compiler but you may prefer to use Exceptions that extend Exception Class to control the behaviour of your api clients as they are required to catch errors for them to compile. Also forms good documentation.
If want to achieve clean interface use inheritance to subclass the different types of exception your application has and then expose the parent exception.
In java, there are two types of parameters, implicit parameters and explicit parameters. Explicit parameters are the arguments passed into a method. The implicit parameter of a method is the instance that the method is called from. Arguments are simply one of the two types of parameters.
In Python, how can I parse a numeric string like "545.2222" to its corresponding float value, 542.2222? Or parse the string "31" to an integer, 31? I just want to know how to parse a float string to a float, and (separately) an int string to an int.
It's good that you ask to do these separately. If you're mixing them, you may be setting yourself up for problems later. The simple answer is:
"545.2222"
to float:
>>> float("545.2222")
545.2222
"31"
to an integer:
>>> int("31")
31
Conversions from various bases, and you should know the base in advance (10 is the default). Note you can prefix them with what Python expects for its literals (see below) or remove the prefix:
>>> int("0b11111", 2)
31
>>> int("11111", 2)
31
>>> int('0o37', 8)
31
>>> int('37', 8)
31
>>> int('0x1f', 16)
31
>>> int('1f', 16)
31
If you don't know the base in advance, but you do know they will have the correct prefix, Python can infer this for you if you pass 0
as the base:
>>> int("0b11111", 0)
31
>>> int('0o37', 0)
31
>>> int('0x1f', 0)
31
If your motivation is to have your own code clearly represent hard-coded specific values, however, you may not need to convert from the bases - you can let Python do it for you automatically with the correct syntax.
You can use the apropos prefixes to get automatic conversion to integers with the following literals. These are valid for Python 2 and 3:
Binary, prefix 0b
>>> 0b11111
31
Octal, prefix 0o
>>> 0o37
31
Hexadecimal, prefix 0x
>>> 0x1f
31
This can be useful when describing binary flags, file permissions in code, or hex values for colors - for example, note no quotes:
>>> 0b10101 # binary flags
21
>>> 0o755 # read, write, execute perms for owner, read & ex for group & others
493
>>> 0xffffff # the color, white, max values for red, green, and blue
16777215
If you see an integer that starts with a 0, in Python 2, this is (deprecated) octal syntax.
>>> 037
31
It is bad because it looks like the value should be 37
. So in Python 3, it now raises a SyntaxError
:
>>> 037
File "<stdin>", line 1
037
^
SyntaxError: invalid token
Convert your Python 2 octals to octals that work in both 2 and 3 with the 0o
prefix:
>>> 0o37
31
Looks like you weren't providing the correct options. For wrapping labels, provide at least:
CGRect paragraphRect =
[attributedText boundingRectWithSize:CGSizeMake(300.f, CGFLOAT_MAX)
options:(NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading)
context:nil];
Note: if the original text width is under 300.f there won't be line wrapping, so make sure the bound size is correct, otherwise you will still get wrong results.
If you compile with debug symbols, you can use objdump
to produce a more readable disassembly.
>objdump --help
[...]
-S, --source Intermix source code with disassembly
-l, --line-numbers Include line numbers and filenames in output
objdump -drwC -Mintel
is nice:
-r
shows symbol names on relocations (so you'd see puts
in the call
instruction below)-R
shows dynamic-linking relocations / symbol names (useful on shared libraries)-C
demangles C++ symbol names-w
is "wide" mode: it doesn't line-wrap the machine-code bytes-Mintel
: use GAS/binutils MASM-like .intel_syntax noprefix
syntax instead of AT&T-S
: interleave source lines with disassembly.You could put something like alias disas="objdump -drwCS -Mintel"
in your ~/.bashrc
Example:
> gcc -g -c test.c
> objdump -d -M intel -S test.o
test.o: file format elf32-i386
Disassembly of section .text:

3: 83 e4 f0 and esp,0xfffffff0

puts("test");
9: c7 04 24 00 00 00 00 mov DWORD PTR [esp],0x0
10: e8 fc ff ff ff call 11 <main+0x11>
return 0;
15: b8 00 00 00 00 mov eax,0x0
}
1a: c9 leave
1b: c3 ret
Note that this isn't using -r
so the call rel32=-4
isn't annotated with the puts
symbol name. And looks like a broken call
that jumps into the middle of the call instruction in main. Remember that the rel32
displacement in the call encoding is just a placeholder until the linker fills in a real offset (to a PLT stub in this case, unless you statically link libc).

Most opensource projects use GetText for this purpose. I don't know how and if it's ever been used on a .Net project before.
You can use a TextBox
and set multiline

and canEdit
to false
.
Just sample code:
import time
timestamp = int(time.time()*1000.0)

Try This, It's working for me .

Firstly, the below method doesn't compile as it is missing the return type and it should be Long.MAX_VALUE
in place of Long.Max_value
.
public static boolean isBiggerThanMaxLong(long value) {
return value > Long.Max_value;
}
The above method can never return true
as you are comparing a long
value with Long.MAX_VALUE
, see the method signature you can pass only long
there.Any long
can be as big as the Long.MAX_VALUE
, it can't be bigger than that.
You can try something like this with BigInteger class :
public static boolean isBiggerThanMaxLong(BigInteger l){
return l.compareTo(BigInteger.valueOf(Long.MAX_VALUE))==1?true:false;
}
The below code will return true
:
BigInteger big3 = BigInteger.valueOf(Long.MAX_VALUE).
add(BigInteger.valueOf(Long.MAX_VALUE));
System.out.println(isBiggerThanMaxLong(big3)); // prints true
If you bind events to the onmouseover and onmouseout events in Jquery, you can then trigger that effect using mouseenter().
What are you trying to accomplish?
Expanding on the answer provided by @Mikko you can use a neat trick to speed things up without having to "know" your column classes ahead of time. Simply use read.xlsx
to grab a limited number of records to determine the classes and then followed it up with read.xlsx2
Example
# just the first 50 rows should do...
df.temp <- read.xlsx("filename.xlsx", 1, startRow=1, endRow=50)
df.real <- read.xlsx2("filename.xlsx", 1,
colClasses=as.vector(sapply(df.temp, mode)))
I would use the algorithm detailed in the bug report using System.getenv(String), and fallback to using the user.dir property if none of the environment variables indicated a valid existing directory. This should work cross-platform.
I think, under Windows, what you are really after is the user's notional "documents" directory.
I already had this same issue and I've got the solution writing a container (.divtagABS-container, in your case) absolutely positioned and then relatively positioning the content inside it (.divtagABS, in your case).
Done! The margin-left and margin-right AUTO for your .divtagABS will now work.
This works well for VARCHAR where it begins with a number or not..

WAR file is just a JAR file, to extract it, just issue following jar command –
jar -xvf yourWARfileName.war
If the jar command is not found, which sometimes happens in the Windows command prompt, then specify full path i.e. in my case it is,
c:\java\jdk-1.7.0\bin\jar -xvf my-file.war
Recent versions of Cordova have the version number in www/cordova.js.
Using CSS you can just set display:none for the element in a CSS file or in a style attribute
#div { display:none; }
<div id="div"></div>
<div style="display:none"></div>
or having the js just after the div might be fast enough too, but not as clean
You have to look how this is called:
someObject.equals(someOtherObj);
This invokes the equals
method on the instance of someObject
. Now, inside that method:
public boolean equals(Object obj) { if (obj == this) { //is someObject equal to obj, which in this case is someOtherObj? return true;//If so, these are the same objects, and return true }
You can see that this
is referring to the instance of the object that equals is called on. Note that equals()
is non-static, and so must be called only on objects that have been instantiated.
Note that ==
is only checking to see if there is referential equality; that is, the reference of this
and obj
are pointing to the same place in memory. Such references are naturally equal:
Object a = new Object(); Object b = a; //sets the reference to b to point to the same place as a Object c = a; //same with c b.equals(c);//true, because everything is pointing to the same place
Further note that equals()
is generally used to also determine value equality. Thus, even if the object references are pointing to different places, it will check the internals to determine if those objects are the same:
FancyNumber a = new FancyNumber(2);//Internally, I set a field to 2 FancyNumber b = new FancyNumber(2);//Internally, I set a field to 2 a.equals(b);//true, because we define two FancyNumber objects to be equal if their internal field is set to the same thing.
setup.py is designed to be run from the command line. You'll need to open your command prompt (In Windows 7, hold down shift while right-clicking in the directory with the setup.py file. You should be able to select "Open Command Window Here").
From the command line, you can type
python setup.py --help
...to get a list of commands. What you are looking to do is...
python setup.py install
You can install openssl
using one single line if you have chocolatey installed

NULL-safe condition would looks like:

The first example doesn't work because you can't assign values to arrays - arrays work (sort of) like const pointers in this respect. What you can do though is copy a new value into the array:
strcpy(p.name, "Jane");
Char arrays are fine to use if you know the maximum size of the string in advance, e.g. in the first example you are 100% sure that the name will fit into 19 characters (not 20 because one character is always needed to store the terminating zero value).
Conversely, pointers are better if you don't know the possible maximum size of your string, and/or you want to optimize your memory usage, e.g. avoid reserving 512 characters for the name "John". However, with pointers you need to dynamically allocate the buffer they point to, and free it when not needed anymore, to avoid memory leaks.
Update: example of dynamically allocated buffers (using the struct definition in your 2nd example):
char* firstName = "Johnnie";
char* surname = "B. Goode";
person p;
p.name = malloc(strlen(firstName) + 1);
p.surname = malloc(strlen(surname) + 1);
p.age = 25;
strcpy(p.name, firstName);
strcpy(p.surname, surname);
printf("Name: %s; Age: %d\n",p.name,p.age);
free(p.surname);
free(p.name);
In Qt 4.7, there is the QDateTime::currentMSecsSinceEpoch()
static function, which does exactly what you need, without any intermediary steps. Hence I'd recommend that for projects using Qt 4.7 or newer.
I created this code for creating a nice, readable csv files:
var objectToCSVRow = function(dataObject) {
var dataArray = new Array;
for (var o in dataObject) {
var innerValue = dataObject[o]===null?'':dataObject[o].toString();
var result = innerValue.replace(/"/g, '""');
result = '"' + result + '"';
dataArray.push(result);
}
return dataArray.join(' ') + '\r\n';
}
var exportToCSV = function(arrayOfObjects) {
if (!arrayOfObjects.length) {
return;
}
var csvContent = "data:text/csv;charset=utf-8,";
// headers
csvContent += objectToCSVRow(Object.keys(arrayOfObjects[0]));
arrayOfObjects.forEach(function(item){
csvContent += objectToCSVRow(item);
});
var encodedUri = encodeURI(csvContent);
var link = document.createElement("a");
link.setAttribute("href", encodedUri);
link.setAttribute("download", "customers.csv");
document.body.appendChild(link); // Required for FF
link.click();
document.body.removeChild(link);
}
In your case, since you use arrays in array instead of objects in array, You will skip the header part, but you could add the column names yourself by putting this instead of that part:
// headers
csvContent += '"Column name 1" "Column name 2" "Column name 3"\n';
The secret is that a space separates the columns in the csv file, and we put the column values in the double quotes to allow spaces, and escape any double quotes in the values themselves.
Also note that I replace null values with empty string, because that suited my needs, but you can change that and replace it with anything you like.
If feed isn't well-formed XML, you're supposed to reject it, no exceptions. You're entitled to call feed creator a bozo.
Otherwise you're paving way to mess that HTML ended up in.
What you want to do is referred to as "squashing" in git. There are lots of options when you're doing this (too many?) but if you just want to merge all of your unpushed commits into a single commit, do this:
git rebase -i origin/master
This will bring up your text editor (-i
is for "interactive") with a file that looks like this:
pick 16b5fcc Code in, tests not passing
pick c964dea Getting closer
pick 06cf8ee Something changed
pick 396b4a3 Tests pass
pick 9be7fdb Better comments
pick 7dba9cb All done
Change all the pick
to squash
(or s
) except the first one:
pick 16b5fcc Code in, tests not passing
squash c964dea Getting closer
squash 06cf8ee Something changed
squash 396b4a3 Tests pass
squash 9be7fdb Better comments
squash 7dba9cb All done
Save your file and exit your editor. Then another text editor will open to let you combine the commit messages from all of the commits into one big commit message.
Voila! Googling "git squashing" will give you explanations of all the other options available.
Static classes can be useful in certain situations, but there is a potential to abuse and/or overuse them, like most language features.
As Dylan Smith already mentioned, the most obvious case for using a static class is if you have a class with only static methods. There is no point in allowing developers to instantiate such a class.
The caveat is that an overabundance of static methods may itself indicate a flaw in your design strategy. I find that when you are creating a static function, its a good to ask yourself -- would it be better suited as either a) an instance method, or b) an extension method to an interface. The idea here is that object behaviors are usually associated with object state, meaning the behavior should belong to the object. By using a static function you are implying that the behavior shouldn't belong to any particular object.
Polymorphic and interface driven design are hindered by overusing static functions -- they cannot be overriden in derived classes nor can they be attached to an interface. Its usually better to have your 'helper' functions tied to an interface via an extension method such that all instances of the interface have access to that shared 'helper' functionality.
One situation where static functions are definitely useful, in my opinion, is in creating a .Create() or .New() method to implement logic for object creation, for instance when you want to proxy the object being created,
public class Foo
{
public static Foo New(string fooString)
{
ProxyGenerator generator = new ProxyGenerator();
return (Foo)generator.CreateClassProxy
(typeof(Foo), new object[] { fooString }, new Interceptor());
}
This can be used with a proxying framework (like Castle Dynamic Proxy) where you want to intercept / inject functionality into an object, based on say, certain attributes assigned to its methods. The overall idea is that you need a special constructor because technically you are creating a copy of the original instance with special added functionality.
I know the question is about GCC, but I thought it might be useful to have some information about compilers other compilers as well.
GCC's
noinline
function attribute is pretty popular with other compilers as well. It
is supported by at least:
__has_attribute(noinline)
)__TI_GNU_ATTRIBUTE_SUPPORT__
)Additionally, MSVC supports
__declspec(noinline)
back to Visual Studio 7.1. Intel probably supports it too (they try to
be compatible with both GCC and MSVC), but I haven't bothered to
verify that. The syntax is basically the same:
__declspec(noinline)
static void foo(void) { }
PGI 10.2+ (and probably older) supports a noinline
pragma which
applies to the next function:
#pragma noinline
static void foo(void) { }
TI 6.0+ supports a
FUNC_CANNOT_INLINE
pragma which (annoyingly) works differently in C and C++. In C++, it's similar to PGI's:
#pragma FUNC_CANNOT_INLINE;
static void foo(void) { }
In C, however, the function name is required:
#pragma FUNC_CANNOT_INLINE(foo);
static void foo(void) { }
Cray 6.4+ (and possibly earlier) takes a similar approach, requiring the function name:
#pragma _CRI inline_never foo
static void foo(void) { }
Oracle Developer Studio also supports a pragma which takes the function name, going back to at least Forte Developer 6, but note that it needs to come after the declaration, even in recent versions:
static void foo(void);
#pragma no_inline(foo)
Depending on how dedicated you are, you could create a macro that would work everywhere, but you would need to have the function name as well as the declaration as arguments.
If, OTOH, you're okay with something that just works for most people, you can get away with something which is a little more aesthetically pleasing and doesn't require repeating yourself. That's the approach I've taken for Hedley, where the current version of HEDLEY_NEVER_INLINE looks like:
#if \
HEDLEY_GNUC_HAS_ATTRIBUTE(noinline,4,0,0) || \
HEDLEY_INTEL_VERSION_CHECK(16,0,0) || \
HEDLEY_SUNPRO_VERSION_CHECK(5,11,0) || \
HEDLEY_ARM_VERSION_CHECK(4,1,0) || \
HEDLEY_IBM_VERSION_CHECK(10,1,0) || \
HEDLEY_TI_VERSION_CHECK(8,0,0) || \
(HEDLEY_TI_VERSION_CHECK(7,3,0) && defined(__TI_GNU_ATTRIBUTE_SUPPORT__))
# define HEDLEY_NEVER_INLINE __attribute__((__noinline__))
#elif HEDLEY_MSVC_VERSION_CHECK(13,10,0)
# define HEDLEY_NEVER_INLINE __declspec(noinline)
#elif HEDLEY_PGI_VERSION_CHECK(10,2,0)
# define HEDLEY_NEVER_INLINE _Pragma("noinline")
#elif HEDLEY_TI_VERSION_CHECK(6,0,0)
# define HEDLEY_NEVER_INLINE _Pragma("FUNC_CANNOT_INLINE;")
#else
# define HEDLEY_NEVER_INLINE HEDLEY_INLINE
#endif
If you don't want to use Hedley (it's a single public domain / CC0 header) you can convert the version checking macros without too much effort, but more than I'm willing to put in ?.
This builds on the answer from JaredPar... and is for VS2017. The same "Build and Run" options are present in Visual Studio 2017.
I was getting, The command "chmod +x """ exited with code 1
In the build output window, I searched for "Error" and found a few errors in the same general area. I was able to click on a link in the build output, and found that the error involved this entry in the .targets file:
<Target Name="ChmodChromeDriver" BeforeTargets="BeforeBuild" Condition="'$(WebDriverPlatform)' != 'win32'">
<Exec Command="chmod +x "$(ChromeDriverSrcPath)"" />
</Target>
In the build output, I also found a more detailed error message that essentially stated that it couldn't find Selenium.WebDriver.ChromeDriver v2.36 in the packages folder it was looking in. I checked the project's NuGet packages, and version 2.36 was indeed in the list of installed packages. I did find the package files for 2.36, and changed the attributes on the folder, subfolders and files from "Read Only" to "Read/Write". Built, but same failure. Sometimes "updating" to a different version of the package and then updating back to the original can fix this type of error. So I "updated" the reference in Manage NuGet packages to 2.37, built, failed, then "updated" back to 2.36, built, and the build succeeded without the "chmod +x" error message.
The project I was building was based on a Visual Studio Project template for Appium test tooling, template name "Develop_Automated_Test".
If you you want to copy a sub-set of the source table you can do:
INSERT INTO def (field_1, field_2, field3)
SELECT other_field_1, other_field_2, other_field_3 from `abc`
or to copy ALL fields from the source table to destination table you can do more simply:
INSERT INTO def
SELECT * from `abc`
in my case closing the visual studio code then starting the server did the trick
Operating system - ubuntu 16.4 lts

I have used <div class="container-fluid" style="padding: 0px !important">

Simply save it with a .pyw
extension. This will prevent the console window from opening.
On Windows systems, there is no notion of an “executable mode”. The Python installer automatically associates .py files with python.exe so that a double-click on a Python file will run it as a script. The extension can also be .pyw, in that case, the console window that normally appears is suppressed.
This worked for me, as documented on this page:
TransformerFactory tf = TransformerFactory.newInstance();
Transformer trans = tf.newTransformer();
StringWriter sw = new StringWriter();
trans.transform(new DOMSource(document), new StreamResult(sw));
return sw.toString();
I learnt Ruby with the help of Mr. Neighborly's Humble Little Ruby Book. It's an excellent free-to-download introduction to Ruby with lots of examples, which I'd 100% recommend.

It really depends on whether or not you can trust s.Length
. For many streams, you just don't know how much data there will be. In such cases - and before .NET 4 - I'd use code like this:
public static byte[] ReadFully(Stream input)
{
byte[] buffer = new byte[16*1024];
using (MemoryStream ms = new MemoryStream())
{
int read;
while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
{
ms.Write(buffer, 0, read);
}
return ms.ToArray();
}
}
With .NET 4 and above, I'd use Stream.CopyTo
, which is basically equivalent to the loop in my code - create the MemoryStream
, call stream.CopyTo(ms)
and then return ms.ToArray()
. Job done.
I should perhaps explain why my answer is longer than the others. Stream.Read
doesn't guarantee that it will read everything it's asked for. If you're reading from a network stream, for example, it may read one packet's worth and then return, even if there will be more data soon. BinaryReader.Read
will keep going until the end of the stream or your specified size, but you still have to know the size to start with.
The above method will keep reading (and copying into a MemoryStream
) until it runs out of data. It then asks the MemoryStream
to return a copy of the data in an array. If you know the size to start with - or think you know the size, without being sure - you can construct the MemoryStream
to be that size to start with. Likewise you can put a check at the end, and if the length of the stream is the same size as the buffer (returned by MemoryStream.GetBuffer
) then you can just return the buffer. So the above code isn't quite optimised, but will at least be correct. It doesn't assume any responsibility for closing the stream - the caller should do that.
See this article for more info (and an alternative implementation).

Not sure what isn't working in your case, but the following code will put a formula into cell A1 that will retrieve the value in the cell G2.
strProjectName = "Sheet1"
Cells(1, 1).Formula = "=" & strProjectName & "!" & Cells(2, 7).Address
The workbook and worksheet that strProjectName
references must exist at the time that this formula is placed. Excel will immediately try to evaluate the formula. You might be able to stop that from happening by turning off automatic recalculation until the workbook does exist.
I find this Java version manager called Jabba recently and the usage is very similar to version managers of other languages like rvm(ruby), nvm(node), pyenv(python), etc. Also it's cross platform so definitely it can be used on Mac.
After installation, it will create a dir in ~/.jabba to put all the Java versions you install. It "Supports installation of Oracle JDK (default) / Server JRE, Zulu OpenJDK (since 0.3.0), IBM SDK, Java Technology Edition (since 0.6.0) and from custom URLs.".
Basic usage is listed on their Github. A quick summary to start:
curl -sL https://github.com/shyiko/jabba/raw/master/install.sh | bash && . ~/.jabba/jabba.sh
# install Oracle JDK
jabba install 1.8 # "jabba use 1.8" will be called automatically
jabba install 1.7 # "jabba use 1.7" will be called automatically
# list all installed JDK's
jabba ls
# switch to a different version of JDK
jabba use 1.8
In my case, I had to uninstall pip and reinstall it. So I could install my specific version.

Thought of writing this answer as nothing worked from above & you don't want to specify proxy location.
If you're using httpClient
then consider this.
HttpClientHandler handler = new HttpClientHandler();
IWebProxy proxy = WebRequest.GetSystemWebProxy();
proxy.Credentials = CredentialCache.DefaultCredentials;
handler.Proxy = proxy;
var client = new HttpClient(handler);
// your next steps...
And if you're using HttpWebRequest
:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri + _endpoint);
IWebProxy proxy = WebRequest.GetSystemWebProxy();
proxy.Credentials = CredentialCache.DefaultCredentials;
request.Proxy = proxy;

Example 1:
This is how the and operator works.
x and y => if x is false, then x, else y
So in other words, since mylist1
is not False
, the result of the expression is mylist2
. (Only empty lists evaluate to False
.)
Example 2:
The &
operator is for a bitwise and, as you mention. Bitwise operations only work on numbers. The result of a & b is a number composed of 1s in bits that are 1 in both a and b. For example:
>>> 3 & 1
1
It's easier to see what's happening using a binary literal (same numbers as above):
>>> 0b0011 & 0b0001
0b0001
Bitwise operations are similar in concept to boolean (truth) operations, but they work only on bits.
So, given a couple statements about my car
The logical "and" of these two statements is:
(is my car red?) and (does car have wheels?) => logical true of false value
Both of which are true, for my car at least. So the value of the statement as a whole is logically true.
The bitwise "and" of these two statements is a little more nebulous:
(the numeric value of the statement 'my car is red') & (the numeric value of the statement 'my car has wheels') => number
If python knows how to convert the statements to numeric values, then it will do so and compute the bitwise-and of the two values. This may lead you to believe that &
is interchangeable with and
, but as with the above example they are different things. Also, for the objects that can't be converted, you'll just get a TypeError
.
Example 3 and 4:
Numpy implements arithmetic operations for arrays:
Arithmetic and comparison operations on ndarrays are defined as element-wise operations, and generally yield ndarray objects as results.
But does not implement logical operations for arrays, because you can't overload logical operators in python. That's why example three doesn't work, but example four does.
So to answer your and
vs &
question: Use and
.
The bitwise operations are used for examining the structure of a number (which bits are set, which bits aren't set). This kind of information is mostly used in low-level operating system interfaces (unix permission bits, for example). Most python programs won't need to know that.
The logical operations (and
, or
, not
), however, are used all the time.
This is what's killing you:
task.Wait();
That's blocking the UI thread until the task has completed - but the task is an async method which is going to try to get back to the UI thread after it "pauses" and awaits an async result. It can't do that, because you're blocking the UI thread...
There's nothing in your code which really looks like it needs to be on the UI thread anyway, but assuming you really do want it there, you should use:
private async void Button_Click(object sender, RoutedEventArgs
{
Task<List<MyObject>> task = GetResponse<MyObject>("my url");
var items = await task;
// Presumably use items here
}
Or just:
private async void Button_Click(object sender, RoutedEventArgs
{
var items = await GetResponse<MyObject>("my url");
// Presumably use items here
}
Now instead of blocking until the task has completed, the Button_Click
method will return after scheduling a continuation to fire when the task has completed. (That's how async/await works, basically.)
Note that I would also rename GetResponse
to GetResponseAsync
for clarity.
Yes, it is because you are using auto layout. Setting the view frame and resizing mask will not work.
You should read Working with Auto Layout Programmatically and Visual Format Language.
You will need to get the current constraints, add the text field, adjust the contraints for the text field, then add the correct constraints on the text field.
Try:
alias lock='gnome-screensaver; gnome-screensaver-command --lock'
or
lock() {
gnome-screensaver
gnome-screensaver-command --lock
}

The second solution allows you to use arguments.
The last update for "windows git" did move the git.exe file from the /bin folder to the /cmd folder. So, to use git with IDEs such as webStorm or Android Studio you can use the path :
C:\Users\<user>\AppData\Local\GitHub\PortableGit_<..numbers..>\cmd\git.exe
But if you want to have linux-like commands such as git, ssh, ls, cp under windows powerShell or cmd add to your windows PATH variables :
C:\Users\<user>\AppData\Local\GitHub\PortableGit_<...numbers...>\usr\bin
change <user> and <...numbers...> to your values and reboot!
Also, you will have to update this everytime git updates since it might change the portable folder name. If folder structure changes I will update this post.
Thx @dennisschagt for the comment above! ;)
It's more than 8 years passed and I am surprised, this issue isn't fixed yet...
I struggled with this simple issue since the most upvoted answer by @Martin lets typing multiple separators, i.e. user can type in "12,,,,,,12,1,,21,2,"
Also, the second concern is that on some devices comma is not shown on the numerical keyboard (or requires multiple pressing of a dot button)
Here is my workaround solution, which solves the mentioned problems and lets user typing '.' and ',', but in EditText he will see the only decimal separator which corresponds to current locale:
editText.apply { addTextChangedListener(DoubleTextChangedListener(this)) }
And the text watcher:
open class DoubleTextChangedListener(private val et: EditText) : TextWatcher {
init {
et.inputType = InputType.TYPE_CLASS_NUMBER or InputType.TYPE_NUMBER_FLAG_DECIMAL
et.keyListener = DigitsKeyListener.getInstance("0123456789.,")
}
private val separator = DecimalFormatSymbols.getInstance().decimalSeparator
override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {
//empty
}
@CallSuper
override fun onTextChanged(s: CharSequence, start: Int, before: Int, count: Int) {
et.run {
removeTextChangedListener(this@DoubleTextChangedListener)
val formatted = toLocalizedDecimal(s.toString(), separator)
setText(formatted)
setSelection(formatted.length)
addTextChangedListener(this@DoubleTextChangedListener)
}
}
override fun afterTextChanged(s: Editable?) {
// empty
}
/**
* Formats input to a decimal. Leaves the only separator (or none), which matches [separator].
* Examples:
* 1. [s]="12.12", [separator]=',' -> result= "12,12"
* 2. [s]="12.12", [separator]='.' -> result= "12.12"
* 4. [s]="12,12", [separator]='.' -> result= "12.12"
* 5. [s]="12,12,,..,,,,,34..,", [separator]=',' -> result= "12,1234"
* 6. [s]="12.12,,..,,,,,34..,", [separator]='.' -> result= "12.1234"
* 7. [s]="5" -> result= "5"
*/
private fun toLocalizedDecimal(s: String, separator: Char): String {
val cleared = s.replace(",", ".")
val splitted = cleared.split('.').filter { it.isNotBlank() }
return when (splitted.size) {
0 -> s
1 -> cleared.replace('.', separator).replaceAfter(separator, "")
2 -> splitted.joinToString(separator.toString())
else -> splitted[0]
.plus(separator)
.plus(splitted.subList(1, splitted.size - 1).joinToString(""))
}
}
}
use a static cursor variable and a split function:
declare @comma_delimited_list varchar(4000)
set @comma_delimited_list = '4,7,12,22,19'
declare @cursor cursor
set @cursor = cursor static for
select convert(int, Value) as Id from dbo.Split(@comma_delimited_list) a
declare @id int
open @cursor
while 1=1 begin
fetch next from @cursor into @id
if @@fetch_status <> 0 break
....do something....
end
-- not strictly necessary w/ cursor variables since they will go out of scope like a normal var
close @cursor
deallocate @cursor
Cursors have a bad rep since the default options when declared against user tables can generate a lot of overhead.
But in this case the overhead is quite minimal, less than any other methods here. STATIC tells SQL Server to materialize the results in tempdb and then iterate over that. For small lists like this, it's the optimal solution.
The function you need is CInt
.
ie CInt(PrinterLabel)
See Type Conversion Functions (Visual Basic) on MSDN
Edit: Be aware that CInt and its relatives behave differently in VB.net and VBScript. For example, in VB.net, CInt casts to a 32-bit integer, but in VBScript, CInt casts to a 16-bit integer. Be on the lookout for potential overflows!
One approach is to strip object and functions from main object. And stringify the simpler form
function simpleStringify (object){
var simpleObject = {};
for (var prop in object ){
if (!object.hasOwnProperty(prop)){
continue;
}
if (typeof(object[prop]) == 'object'){
continue;
}
if (typeof(object[prop]) == 'function'){
continue;
}
simpleObject[prop] = object[prop];
}
return JSON.stringify(simpleObject); // returns cleaned up JSON
};
Try calling read_csv
with encoding='latin1'
, encoding='iso-8859-1'
or encoding='cp1252'
(these are some of the various encodings found on Windows).
The prompt command will echo text to the output:

You appear to be trying to mix query expression syntax and "normal" lambda expression syntax. You can either use:
IEnumerable<SelectListItem> stores =
from store in database.Stores
where store.CompanyID == curCompany.ID
select new SelectListItem { Value = store.Name, Text = store.ID};
ViewBag.storeSelector = stores;
Or:
IEnumerable<SelectListItem> stores = database.Stores
.Where(store => store.CompanyID == curCompany.ID)
.Select(s => new SelectListItem { Value = s.Name, Text = s.ID});
ViewBag.storeSelector = stores;
You can't mix the two like you're trying to.
there's no timeout support in the fetch API yet. But it could be achieved by wrapping it in a promise.
for eg.
function fetchWrapper(url, options, timeout) {
return new Promise((resolve, reject) => {
fetch(url, options).then(resolve, reject);
if (timeout) {
const e = new Error("Connection timed out");
setTimeout(reject, timeout, e);
}
});
}
In case that you have Ubuntu in your machine, the following steps will help you:
Open your terminal and paste: sudo apt-get install php-soap.
Restart your apache2 server in terminal : service apache2 restart.
To check use your php test file again to be seems like mine in step 1.
Try get instead for test reasons
<form action="#?name=test" method="GET">
<input type="text" name="firstname" />
<input type="submit" name="submit" value="Submit" />
</form>
and
if(isset($_GET)){
echo $_GET['name'] . '<br>';
echo $_GET['firstname'];
}
Got the same problem, found the following bug report in SQL Server 2012 If still relevant see conditions that cause the issue - there are some workarounds there as well (didn't try though). Failover or Restart Results in Reseed of Identity
I don't think such a thing is possible. You can use SUBSTRING
function to extract the part you want.
Using solve
with a single parameter is a request to invert a matrix. The error message is telling you that your matrix is singular and cannot be inverted.
For a quick n' dirty self-signed cert, you can also use flask run --cert adhoc
or set the FLASK_RUN_CERT
env var.
$ export FLASK_APP="app.py"
$ export FLASK_ENV=development
$ export FLASK_RUN_CERT=adhoc
$ flask run

* Running on https://127.0.0.1:5000/ (Press CTRL+C to quit)
* Restarting with stat
* Debugger is active!
* Debugger PIN: 329-665-000
The adhoc
option isn't well documented (for good reason, never do this in production), but it's mentioned in the cli.py source code.
There's a thorough explanation of this by Miguel Grinberg at Running Your Flask Application Over HTTPS.

Fixing Write Permissions for Chrooted FTP Users in vsftpd
The vsftpd version that comes with Ubuntu 12.04 Precise does not permit chrooted local users to write by default. By default you will have this in /etc/vsftpd.conf:
chroot_local_user=YES write_enable=YES
In order to allow local users to write, you need to add the following parameter:
allow_writeable_chroot=YES
Note: Issues with write permissions may show up as following FileZilla errors:
Error: GnuTLS error -15: An unexpected TLS packet was received.
Error: Could not connect to server
References:
Fixing Write Permissions for Chrooted FTP Users in vsftpd
VSFTPd stopped working after update
The answer by shufler is correct. Stated another way: Instead of passing the values to Write-Output using the ARRAY FORM,
Write-Output "Parameters are:" $Year $Month $Day
or the equivalent by multiple calls to Write-Output,
Write-Output "Parameters are:"
Write-Output $Year
Write-Output $Month
Write-Output $Day
Write-Output "Done."
concatenate your components into a STRING VARIABLE first:
$msg="Parameters are: $Year $Month $Day"
Write-Output $msg
This will prevent the intermediate CRLFs caused by calling Write-Output multiple times (or ARRAY FORM), but of course will not suppress the final CRLF of the Write-Output commandlet. For that, you will have to write your own commandlet, use one of the other convoluted workarounds listed here, or wait until Microsoft decides to support the -NoNewline
option for Write-Output.
Your desire to provide a textual progress meter to the console (i.e. "....") as opposed to writing to a log file, should also be satisfied by using Write-Host. You can accomplish both by collecting the msg text into a variable for writing to the log AND using Write-Host to provide progress to the console. This functionality can be combined into your own commandlet for greatest code reuse.
I could get image width and height by its drawable;
int width = imgView.getDrawable().getIntrinsicWidth();
int height = imgView.getDrawable().getIntrinsicHeight();
Use a seperate column to indicate the join condition
SELECT t.importid,
case
when t.importid = g.home
then 'home'
else 'away'
end as join_condition,
g.network,
g.date_start
FROM game g
INNER JOIN team t ON (t.importid = g.home OR t.importid = g.away)
ORDER BY date_start DESC
LIMIT 7
You need to create an extension of String and call this method
func height(withConstrainedWidth width: CGFloat, font: UIFont) -> CGFloat {
let constraintRect = CGSize(width: width, height: .greatestFiniteMagnitude)
let boundingBox = self.boundingRect(with: constraintRect, options: .usesLineFragmentOrigin, attributes: [NSFontAttributeName: font], context: nil)
return ceil(boundingBox.height)
}
You must send the width of your label
If you're trying to style dynamically added HTML elements inside an Angular component, this might be helpful:
// inside component class...
constructor(private hostRef: ElementRef) { }
getContentAttr(): string {
const attrs = this.hostRef.nativeElement.attributes
for (let i = 0, l = attrs.length; i < l; i++) {
if (attrs[i].name.startsWith('_nghost-c')) {
return `_ngcontent-c${attrs[i].name.substring(9)}`
}
}
}
ngAfterViewInit() {
// dynamically add HTML element
dynamicallyAddedHtmlElement.setAttribute(this.getContentAttr(), '')
}
My guess is that the convention for this attribute is not guaranteed to be stable between versions of Angular, so that one might run into problems with this solution when upgrading to a new version of Angular (although, updating this solution would likely be trivial in that case).
You can create a datasource bean in servlet context as:

First, you'll need to tell git about yourself. Get your username and token together from your settings page.
Then run:
git config --global github.user YOUR_USERNAME
git config --global github.token YOURTOKEN
You will need to generate a new key if you don't have a back-up of your key.
Then you should be able to run:
git clone [email protected]:YOUR_USERNAME/YOUR_PROJECT.git
It would seem that removing http://
from the url option ensures the the correct HTTP POST header is sent.
I dont think you need to fully qualify the name of the host, just use a relative URL as below.
$.ajax({
type: "POST",
contentType: "application/json",
url: '/Hello',
data: { name: 'norm' },
dataType: "json"
});
An example of mine that works:
$.ajax({
type: "POST",
url: siteRoot + "api/SpaceGame/AddPlayer",
async: false,
data: JSON.stringify({ Name: playersShip.name, Credits: playersShip.credits }),
contentType: "application/json",
complete: function (data) {
console.log(data);
wait = false;
}
});
Possibly related: jQuery $.ajax(), $.post sending "OPTIONS" as REQUEST_METHOD in Firefox
Edit: After some more research I found out the OPTIONS header is used to find out if the request from the originating domain is allowed. Using fiddler, I added the following to the response headers from my server.
Access-Control-Allow-Origin: *
Access-Control-Allow-Headers: Content-Type
Access-Control-Allow-Methods: POST, GET, OPTIONS
Once the browser received this response it then sent off the correct POST request with json data. It would seem that the default form-urlencoded content type is considered safe and so does not undergo the extra cross domain checks.
It looks like you will need to add the previously mentioned headers to your servers response to the OPTIONS request. You should of course configure them to allow requests from specific domains rather then all.
I used the following jQuery to test this.
$.ajax({
type: "POST",
url: "http://myDomain.com/path/AddPlayer",
data: JSON.stringify({
Name: "Test",
Credits: 0
}),
//contentType: "application/json",
dataType: 'json',
complete: function(data) {
$("content").html(data);
}
});?

I was pretty sure that you need to specify the NOLOCK
for each JOIN
in the query. But my experience was limited to SQL Server 2005.
When I looked up MSDN just to confirm, I couldn't find anything definite. The below statements do seem to make me think, that for 2008, your two statements above are equivalent though for 2005 it is not the case:
[SQL Server 2008 R2]
All lock hints are propagated to all the tables and views that are accessed by the query plan, including tables and views referenced in a view. Also, SQL Server performs the corresponding lock consistency checks.
[SQL Server 2005]
In SQL Server 2005, all lock hints are propagated to all the tables and views that are referenced in a view. Also, SQL Server performs the corresponding lock consistency checks.
Additionally, point to note - and this applies to both 2005 and 2008:
The table hints are ignored if the table is not accessed by the query plan. This may be caused by the optimizer choosing not to access the table at all, or because an indexed view is accessed instead. In the latter case, accessing an indexed view can be prevented by using the
OPTION (EXPAND VIEWS)
query hint.
In this case what you can do is : Go in developer options on the device Uncheck "USB Debugging" then check it again A confirmation box should then appear DvxWifiScan

We have now (jan2017) a csv layer import inside Google Maps itself.

If I got you correctly, it is as easy as
cartDiv.id = "someID";
No need for jQuery.
Have a look at the properties of a DOM Element.
For classes it is the same:
cartDiv.className = "classes here";
But note that this will overwrite already existing class names. If you want to add and remove classes dynamically, you either have to use jQuery or write your own function that does some string replacement.

Yes you can handle with the catch operator like this and show alert as you want but firstly you have to import Rxjs

return this.http.request(new Request(this.requestoptions))
.map((res: Response) => {
if (res) {
if (res.status === 201) {
return [{ status: res.status, json: res }]
}
else if (res.status === 200) {
return [{ status: res.status, json: res }]
}
}
}).catch((error: any) => {
if (error.status === 500) {
return Observable.throw(new Error(error.status));
}
else if (error.status === 400) {
return Observable.throw(new Error(error.status));
}
else if (error.status === 409) {
return Observable.throw(new Error(error.status));
}
else if (error.status === 406) {
return Observable.throw(new Error(error.status));
}
});
}
also you can handel error (with err block) that is throw by catch block while .map
function,
like this -
...
.subscribe(res=>{....}
err => {//handel here});
as required for any status without checking particluar one you can try this: -
return this.http.request(new Request(this.requestoptions))
.map((res: Response) => {
if (res) {
if (res.status === 201) {
return [{ status: res.status, json: res }]
}
else if (res.status === 200) {
return [{ status: res.status, json: res }]
}
}
}).catch((error: any) => {
if (error.status < 400 || error.status ===500) {
return Observable.throw(new Error(error.status));
}
})
.subscribe(res => {...},
err => {console.log(err)} );

I think you are talking about ctrl + shift + F, by default it should be on "look in: entire solution" and there you go.
The problem for me was not got the port from process.env.PORT
it is very important because Heroku and other services properly do a random port numbers to use.
So that is the code that work for me eventuly :
var app = require('express')();
var http = require('http').createServer(app);
const serverPort = process.env.PORT ; //<----- important
const io = require('socket.io')(http,{
cors: {
origin: '*',
methods: 'GET,PUT,POST,DELETE,OPTIONS'.split(','),
credentials: true
}
});
http.listen(serverPort,()=>{
console.log(`server listening on port ${serverPort}`)
})
For get the left part of the URL:
?HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority)
"http://localhost:1714"
For get the application (web) name:
?HttpRuntime.AppDomainAppVirtualPath
"/"
With this, you are available to add your relative path after that obtaining the complete URL.
Use data type 'MultilineText':
[DataType(DataType.MultilineText)]
public string Text { get; set; }
The solutions above though they will get the job done do so at the risk of dropping user permissions. I prefer to do my create or replace views or stored procedures as follows.
IF NOT EXISTS (SELECT * FROM sys.views WHERE object_id = OBJECT_ID(N'[dbo].[vw_myView]'))
EXEC sp_executesql N'CREATE VIEW [dbo].[vw_myView] AS SELECT ''This is a code stub which will be replaced by an Alter Statement'' as [code_stub]'
GO
ALTER VIEW [dbo].[vw_myView]
AS
SELECT 'This is a code which should be replaced by the real code for your view' as [real_code]
GO
But this is obviously performing a 'string' comparison
No. The string will be automatically cast into a DATETIME value.
See 11.2. Type Conversion in Expression Evaluation.
When an operator is used with operands of different types, type conversion occurs to make the operands compatible. Some conversions occur implicitly. For example, MySQL automatically converts numbers to strings as necessary, and vice versa.
Actually we get this error also when we create canvas in javascript as below.
document.createElement('canvas');
Here point to be noted we have to provide argument name correctly as 'canvas' not anything else.
Thanks
If you have to set your anchor tag inside the div, you can also use CSS to set the anchor to fill the div via display:block.
As such:
<div style="height: 80px"><a href="#" style="display: block">Text</a></div>
Now when the user floats their cursor in that div the anchor tag will fill the div.
Usually I create Fowler's Range implementation for such things.
public interface IRange<T>
{
T Start { get; }
T End { get; }
bool Includes(T value);
bool Includes(IRange<T> range);
}
public class DateRange : IRange<DateTime>
{
public DateRange(DateTime start, DateTime end)
{
Start = start;
End = end;
}
public DateTime Start { get; private set; }
public DateTime End { get; private set; }
public bool Includes(DateTime value)
{
return (Start <= value) && (value <= End);
}
public bool Includes(IRange<DateTime> range)
{
return (Start <= range.Start) && (range.End <= End);
}
}
Usage is pretty simple:
DateRange range = new DateRange(startDate, endDate);
range.Includes(date)
Applying the DRY principle to Omar's solution, here's an HTML Helper extension:
using System.Web.Mvc;
using System.Text.RegularExpressions;
namespace System.Web.Mvc.Html {
public static class MyHtmlHelpers {
public static MvcHtmlString EncodedReplace(this HtmlHelper helper, string input, string pattern, string replacement) {
return new MvcHtmlString(Regex.Replace(helper.Encode(input), pattern, replacement));
}
}
}
Usage (with improved regex):
@Html.EncodedReplace(Model.CommentText, "[\n\r]+", "<br />")
This also has the added benefit of putting less onus on the Razor View developer to ensure security from XSS vulnerabilities.
My concern with Jacob's solution is that rendering the line breaks with CSS breaks the HTML semantics.
Depending on devices you might not find sqlite3 command in adb shell. In that case you might want to follow this :
adb shell
$ run-as package.name
$ cd ./databases/
$ ls -l #Find the current permissions - r=4, w=2, x=1
$ chmod 666 ./dbname.db
$ exit
$ exit
adb pull /data/data/package.name/databases/dbname.db ~/Desktop/
adb push ~/Desktop/dbname.db /data/data/package.name/databases/dbname.db
adb shell
$ run-as package.name
$ chmod 660 ./databases/dbname.db #Restore original permissions
$ exit
$ exit
for reference go to https://stackoverflow.com/a/17177091/3758972.
There might be cases when you get "remote object not found" after following above procedure. Then change permission of your database folder to 755 in adb shell.
$ chmod 755 databases/
But please mind that it'll work only on android version < 21.
I found out that my back-up project worked well if I precompile without bundle update
. Maybe something went wrong with gem updated but I don't know which gem has an error.
A bit late on this one but this worked perfectly for me when trying to hide the background for IE6 & 7
.myclass{
background-image: url("images/myimg.png");
background-position: right top;
background-repeat: no-repeat;
background-size: 22px auto;
padding-left: 48px;
height: 42px;
_background-image: none;
*background-image: none;
}
I got this hack via: http://briancray.com/posts/target-ie6-and-ie7-with-only-1-extra-character-in-your-css/
#myelement
{
color: #999; /* shows in all browsers */
*color: #999; /* notice the * before the property - shows in IE7 and below */
_color: #999; /* notice the _ before the property - shows in IE6 and below */
}
To find them, you can use this
;WITH cte AS
(
SELECT 0 AS CharCode
UNION ALL
SELECT CharCode + 1 FROM cte WHERE CharCode <31
)
SELECT
*
FROM
mytable T
cross join cte
WHERE
EXISTS (SELECT *
FROM mytable Tx
WHERE Tx.PKCol = T.PKCol
AND
Tx.MyField LIKE '%' + CHAR(cte.CharCode) + '%'
)
Replacing the EXISTS with a JOIN will allow you to REPLACE them, but you'll get multiple rows... I can't think of a way around that...
You can use this in your case, it will work fine.
user = UniversityDetails.objects.filter(email=email).first()
If you're using QT Creator 5.6 you can do that like this:
#include <QIntValidator>
ui->myLineEditName->setValidator( new QIntValidator);
I recomend you put that line after ui->setupUi(this);
I hope this helps.
I was facing some difficulties with an environment variable that is with custom name (not with container name /port convention for KAPACITOR_BASE_URL and KAPACITOR_ALERTS_ENDPOINT). If we give service name in this case it wouldn't resolve the ip as
KAPACITOR_BASE_URL: http://kapacitor:9092
In above http://[**kapacitor**]:9092
would not resolve to http://172.20.0.2:9092

Your question can be conveniently divided into several parts:
Does a VPN hide location? Yes, he is capable of this. This is not about GPS determining your location. If you try to change the region via VPN in an application that requires GPS access, nothing will work. However, sites define your region differently. They get an IP address and see what country or region it belongs to. If you can change your IP address, you can change your region. This is exactly what VPNs can do.
How to hide location on Android? There is nothing difficult in figuring out how to set up a VPN on Android, but a couple of nuances still need to be highlighted. Let's start with the fact that not all Android VPNs are created equal. For example, VeePN outperforms many other services in terms of efficiency in circumventing restrictions. It has 2500+ VPN servers and a powerful IP and DNS leak protection system.
You can easily change the location of your Android device by using a VPN. Follow these steps for any device model (Samsung, Sony, Huawei, etc.):
Download and install a trusted VPN.
Install the VPN on your Android device.
Open the application and connect to a server in a different country.
Your Android location will now be successfully changed!
Is it legal? Yes, changing your location on Android is legal. Likewise, you can change VPN settings in Microsoft Edge on your PC, and all this is within the law. VPN allows you to change your IP address, safeguarding your privacy and protecting your actual location from being exposed. However, VPN laws may vary from country to country. There are restrictions in some regions.
Brief summary: Yes, you can change your region on Android and a VPN is a necessary assistant for this. It's simple, safe and legal. Today, VPN is the best way to change the region and unblock sites with regional restrictions.

<button OnClick=" location.href='link.html' ">Visit Page Now</button>
Although, it's been a while since I've touched JavaScript - maybe location.href
is outdated? Anyways, that's how I would do it.
Here is @Vitaliy Gozhenko's answer, in Swift.
To summarize you will create a UITableViewHeaderFooterView that contains a UITableViewCell. This UITableViewCell will be "dequeuable" and you can design it in your storyboard.
Create a UITableViewHeaderFooterView class
class CustomHeaderFooterView: UITableViewHeaderFooterView {
var cell : UITableViewCell? {
willSet {
cell?.removeFromSuperview()
}
didSet {
if let cell = cell {
cell.frame = self.bounds
cell.autoresizingMask = [UIViewAutoresizing.FlexibleHeight, UIViewAutoresizing.FlexibleWidth]
self.contentView.backgroundColor = UIColor .clearColor()
self.contentView .addSubview(cell)
}
}
}
Plug your tableview with this class in your viewDidLoad function:
self.tableView.registerClass(CustomHeaderFooterView.self, forHeaderFooterViewReuseIdentifier: "SECTION_ID")
When asking, for a section header, dequeue a CustomHeaderFooterView, and insert a cell into it
func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let view = self.tableView.dequeueReusableHeaderFooterViewWithIdentifier("SECTION_ID") as! CustomHeaderFooterView
if view.cell == nil {
let cell = self.tableView.dequeueReusableCellWithIdentifier("Cell")
view.cell = cell;
}
// Fill the cell with data here
return view;
}
Like this: .
The .
means any character except newline (which sometimes is but often isn't included, check your regex flavour).
You can rewrite your expression as ^.{1,35}$
, which should match any line of length 1-35.
The ssh daemon (sshd), which runs server-side, closes the connection from the server-side if the client goes silent (i.e., does not send information). To prevent connection loss, instruct the ssh client to send a sign-of-life signal to the server once in a while.
The configuration for this is in the file $HOME/.ssh/config
, create the file if it does not exist (the config file must not be world-readable, so run chmod 600 ~/.ssh/config
after creating the file). To send the signal every e.g. four minutes (240 seconds) to the remote host, put the following in that configuration file:
Host remotehost
HostName remotehost.com
ServerAliveInterval 240
To enable sending a keep-alive signal for all hosts, place the following contents in the configuration file:
Host *
ServerAliveInterval 240
To understand why it is necessary to distinguish between int
and long
literals, consider:
long l = -1 >>> 1;
versus
int a = -1;
long l = a >>> 1;
Now as you would rightly expect, both code fragments give the same value to variable l
. Without being able to distinguish int
and long
literals, what is the interpretation of -1 >>> 1
?
-1L >>> 1 // ?
or
(int)-1 >>> 1 // ?
So even if the number is in the common range, we need to specify type. If the default changed with magnitude of the literal, then there would be a weird change in the interpretations of expressions just from changing the digits.
This does not occur for byte
, short
and char
because they are always promoted before performing arithmetic and bitwise operations. Arguably their should be integer type suffixes for use in, say, array initialisation expressions, but there isn't. float
uses suffix f
and double
d
. Other literals have unambiguous types, with there being a special type for null
.
CAST(Round(MySum * 20.0 /100, 0) AS INT)
FYI
MySum * 20 /100, I get 11
This is because when all 3 operands are INTs, SQL Server will do perform integer maths, from left to right, truncating all intermediate results.
58 * 20 / 100 => 1160 / 100 => 11 (truncated from 11.6)
Also for the record ROUND(m,n) returns the result to n decimal places, not n significant figures.
You'll find that instances of list
do not provide a __hash__
--rather, that attribute of each list is actually None
(try print [].__hash__
). Thus, list
is unhashable.
The reason your code works with list
and not set
is because set
constructs a single set of items without duplicates, whereas a list can contain arbitrary data.
ES6/ES2015 version:
import customData from './customData.json';
In Typescript you need to set types of HTMLAttributes
and React.FunctionComponent
.
In most cases you will need will be extending it to another interface or type.
const List: React.FunctionComponent<ListProps &
React.HTMLAttributes<HTMLDivElement>> = (
props: ListProps & React.HTMLAttributes<HTMLDivElement>
) => {
return (
<div className={props.className}>
<img className="mr-3" src={props.icon} alt="" />
{props.context}
</div>
);
};
interface ListProps {
context: string;
icon: string;
}
How are you running the file? Is it from the command line or from an IDE? The directory that your executable is in is not necessarily your working directory.
Try using the full path name in the fopen
and see if that fixes it. If so, then the problem is as described.
For example:
file = fopen("c:\\MyDirectory\\TestFile1.txt", "r");
file = fopen("/full/path/to/TestFile1.txt", "r");
Or open up a command window and navigate to the directory where your executable is, then run it manually.
As an aside, you can insert a simple (for Windows or Linux/UNIX/BSD/etc respectively):
system ("cd")
system("pwd")
before the fopen
to show which directory you're actually in.
I think Quirksmode has all the answers you need (different browsers bubbling behaviour and the mouseenter/mouseleave events), but I think the most common conclusion to that event bubbling mess is the use of a framework like JQuery or Mootools (which has the mouseenter and mouseleave events, which are exactly what you intuited would happen).
Have a look at how they do it, if you want, do it yourself
or you can create your custom "lean mean" version of Mootools with just the event part (and its dependencies).
An accessed dictionary value (a list in this case) is the original value, separate from the dictionary which is used to access it. You would increment the values in the list the same way whether it's in a dictionary or not:
l = dictionary.get('C1')
for i in range(len(l)):
l[i] += 10
If date
and col_date
are the same columns you should simply do:
SELECT A, MAX(date) FROM t GROUP BY A
Why not use:
WITH x AS ( SELECT A, MAX(col_date) m FROM TABLENAME )
SELECT A, date FROM TABLENAME t JOIN x ON x.A = t.A AND x.m = t.col_date
Otherwise:
SELECT A, FIRST_VALUE(date) KEEP(dense_rank FIRST ORDER BY col_date DESC)
FROM TABLENAME
GROUP BY A
Cross platform fastest solution (only uses single fork() for ls, doesn't attempt to count actual characters, doesn't spawn unneeded awk, perl, etc).
Tested on MacOS, Linux - may require minor modification for Solaris:
__ln=( $( ls -Lon "$1" ) )
__size=${__ln[3]}
echo "Size is: $__size bytes"
If required, simplify ls arguments, and adjust offset in ${__ln[3]}.
Note: will follow symlinks.
There are two widely-used memory allocation techniques: automatic allocation and dynamic allocation. Commonly, there is a corresponding region of memory for each: the stack and the heap.
The stack always allocates memory in a sequential fashion. It can do so because it requires you to release the memory in the reverse order (First-In, Last-Out: FILO). This is the memory allocation technique for local variables in many programming languages. It is very, very fast because it requires minimal bookkeeping and the next address to allocate is implicit.
In C++, this is called automatic storage because the storage is claimed automatically at the end of scope. As soon as execution of current code block (delimited using {}
) is completed, memory for all variables in that block is automatically collected. This is also the moment where destructors are invoked to clean up resources.
The heap allows for a more flexible memory allocation mode. Bookkeeping is more complex and allocation is slower. Because there is no implicit release point, you must release the memory manually, using delete
or delete[]
(free
in C). However, the absence of an implicit release point is the key to the heap's flexibility.
Even if using the heap is slower and potentially leads to memory leaks or memory fragmentation, there are perfectly good use cases for dynamic allocation, as it's less limited.
Two key reasons to use dynamic allocation:
You don't know how much memory you need at compile time. For instance, when reading a text file into a string, you usually don't know what size the file has, so you can't decide how much memory to allocate until you run the program.
You want to allocate memory which will persist after leaving the current block. For instance, you may want to write a function string readfile(string path)
that returns the contents of a file. In this case, even if the stack could hold the entire file contents, you could not return from a function and keep the allocated memory block.
In C++ there's a neat construct called a destructor. This mechanism allows you to manage resources by aligning the lifetime of the resource with the lifetime of a variable. This technique is called RAII and is the distinguishing point of C++. It "wraps" resources into objects. std::string
is a perfect example. This snippet:
int main ( int argc, char* argv[] )
{
std::string program(argv[0]);
}
actually allocates a variable amount of memory. The std::string
object allocates memory using the heap and releases it in its destructor. In this case, you did not need to manually manage any resources and still got the benefits of dynamic memory allocation.
In particular, it implies that in this snippet:
int main ( int argc, char* argv[] )
{
std::string * program = new std::string(argv[0]); // Bad!
delete program;
}
there is unneeded dynamic memory allocation. The program requires more typing (!) and introduces the risk of forgetting to deallocate the memory. It does this with no apparent benefit.
Basically, the last paragraph sums it up. Using automatic storage as often as possible makes your programs:
In the referenced question, there are additional concerns. In particular, the following class:
class Line {
public:
Line();
~Line();
std::string* mString;
};
Line::Line() {
mString = new std::string("foo_bar");
}
Line::~Line() {
delete mString;
}
Is actually a lot more risky to use than the following one:
class Line {
public:
Line();
std::string mString;
};
Line::Line() {
mString = "foo_bar";
// note: there is a cleaner way to write this.
}
The reason is that std::string
properly defines a copy constructor. Consider the following program:
int main ()
{
Line l1;
Line l2 = l1;
}
Using the original version, this program will likely crash, as it uses delete
on the same string twice. Using the modified version, each Line
instance will own its own string instance, each with its own memory and both will be released at the end of the program.
Extensive use of RAII is considered a best practice in C++ because of all the reasons above. However, there is an additional benefit which is not immediately obvious. Basically, it's better than the sum of its parts. The whole mechanism composes. It scales.
If you use the Line
class as a building block:
class Table
{
Line borders[4];
};
Then
int main ()
{
Table table;
}
allocates four std::string
instances, four Line
instances, one Table
instance and all the string's contents and everything is freed automagically.
Just using the code below.
import os
os.environ["CUDA_DEVICE_ORDER"] = "PCI_BUS_ID"
os.environ['CUDA_VISIBLE_DEVICES'] = '-1'
Another way to do this is to add the new characters to the string as follows:
Dim str As String
str = ""
To append text to your string this way:
str = str & "and this is more text"
Your code is fine. There's no problem with returning Strings
in this manner.
In Java, a String
is a reference to an immutable object. This, coupled with garbage collection, takes care of much of the potential complexity: you can simply pass a String
around without worrying that it would disapper on you, or that someone somewhere would modify it.
If you don't mind me making a couple of stylistic suggestions, I'd modify the code like so:
public String time_to_string(long t) // time in milliseconds
{
if (t < 0)
{
return "-";
}
else
{
int secs = (int)(t/1000);
int mins = secs/60;
secs = secs - (mins * 60);
return String.format("%d:%02d", mins, secs);
}
}
As you can see, I've pushed the variable declarations as far down as I could (this is the preferred style in C++ and Java). I've also eliminated ans
and have replaced the mix of string concatenation and String.format()
with a single call to String.format()
.

For percent increase and decrease, using 2 different methods:
const a = 541
const b = 394
// Percent increase
console.log(
`Increase (from ${b} to ${a}) => `,
(((a/b)-1) * 100).toFixed(2) + "%",
)
// Percent decrease
console.log(
`Decrease (from ${a} to ${b}) => `,
(((b/a)-1) * 100).toFixed(2) + "%",
)
// Alternatives, using .toLocaleString()
console.log(
`Increase (from ${b} to ${a}) => `,
((a/b)-1).toLocaleString('fullwide', {maximumFractionDigits:2, style:'percent'}),
)
console.log(
`Decrease (from ${a} to ${b}) => `,
((b/a)-1).toLocaleString('fullwide', {maximumFractionDigits:2, style:'percent'}),
)

Two steps. First, extend Activity class
class Example extends Activity
Second: Use this code
DisplayMetrics displayMetrics = new DisplayMetrics();
WindowManager windowmanager = (WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE);
windowmanager.getDefaultDisplay().getMetrics(displayMetrics);
int deviceWidth = displayMetrics.widthPixels;
int deviceHeight = displayMetrics.heightPixels;
if you wanna remove attributes for all files in all folders on whole flash drive do this:
attrib -r -s -h /S /D
this command will remove attrubutes for all files folders and subfolders:
-read only -system file -is hidden -Processes matching files and all subfolders. -Processes folders as well
Here I just want to add some more complex usage.
// Document
{
"_id" : 1
"shapes" : [
{"shape" : "square", "color" : "red"},
{"shape" : "circle", "color" : "green"}
]
}
{
"_id" : 2
"shapes" : [
{"shape" : "square", "color" : "red"},
{"shape" : "circle", "color" : "green"}
]
}
// The Query
db.contents.find({
"_id" : ObjectId(1),
"shapes.color":"red"
},{
"_id": 0,
"shapes" :{
"$elemMatch":{
"color" : "red"
}
}
})
//And the Result
{"shapes":[
{
"shape" : "square",
"color" : "red"
}
]}
Update your view with null value instead of parent viewgroup in Adapter viewholder onCreateViewHolder method.
@Override
public AdapterItemSku.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = inflator.inflate(R.layout.layout_item, null, false);
return new MyViewHolder(view);
}
I don't think using _ or m_ to indicate member variables is bad in Java or any other language. It my opinion it improves readability of your code because it allows you to look at a snippet and quickly identify out all of the member variables from locals.
You can also achieve this by forcing users to prepend instance variables with "this" but I find this slighly draconian. In many ways it violates DRY because it's an instance variable, why qualify it twice.
My own personal style is to use m_ instead of _. The reason being that there are also global and static variables. The advantage to m_/_ is it distinguishes a variables scope. So you can't reuse _ for global or static and instead I choose g_ and s_ respectively.
I always do this, in that case to grab a ref
let input: HTMLInputElement = ReactDOM.findDOMNode<HTMLInputElement>(this.refs.input);
This is for Chrome, in the wake of user800583 answer ...
I spent a few hours on this problem and have not found a better approach, but :
window.outerWidth/window.innerWidth
, and when it is not, the ratio seems to be (window.outerWidth-16)/window.innerWidth
, however the 1st case can be approached by the 2nd one.So I came to the following ...
But this approach has limitations : for example if you play the accordion with the application window (rapidly enlarge and reduce the width of the window) then you will get gaps between zoom levels although the zoom has not changed (may be outerWidth and innerWidth are not exactly updated in the same time).
var snap = function (r, snaps)
{
var i;
for (i=0; i < 16; i++) { if ( r < snaps[i] ) return i; }
};
var w, l, r;
w = window.outerWidth, l = window.innerWidth;
return snap((w - 16) / l,
[ 0.29, 0.42, 0.58, 0.71, 0.83, 0.95, 1.05, 1.18, 1.38, 1.63, 1.88, 2.25, 2.75, 3.5, 4.5, 100 ],
);
And if you want the factor :
var snap = function (r, snaps, ratios)
{
var i;
for (i=0; i < 16; i++) { if ( r < snaps[i] ) return eval(ratios[i]); }
};
var w, l, r;
w = window.outerWidth, l = window.innerWidth;
return snap((w - 16) / l,
[ 0.29, 0.42, 0.58, 0.71, 0.83, 0.95, 1.05, 1.18, 1.38, 1.63, 1.88, 2.25, 2.75, 3.5, 4.5, 100 ],
[ 0.25, '1/3', 0.5, '2/3', 0.75, 0.9, 1, 1.1, 1.25, 1.5, 1.75, 2, 2.5, 3, 4, 5 ]
);
Have you tried this?
$('.myClass, .myOtherClass').removeClass('theclass');
I had the same problem and resolved it by changing the character set of the column. Even though your database has a default character set of utf-8
I think it's possible for database columns to have a different character set in MySQL. Here's the SQL QUERY I used:
ALTER TABLE database.table MODIFY COLUMN col VARCHAR(255)
CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL;
What are dex files: Android app (APK) files contain executable bytecode files in the form of Dalvik Executable (DEX) files, which contain the compiled code used to run your app.
Reason for this exception: The DEX specification limits the total number of methods that can be referenced within a single DEX file to 65,536 (64K reference limit) —including Android framework methods, library methods, and methods in your own code.
Step 01. Add the following dependency as follows
For Non-Androidx Users,
dependencies {
implementation 'com.android.support:multidex:1.0.3'
}
defaultConfig {
minSdkVersion 16
targetSdkVersion 28
multiDexEnabled true //ADD THIS LINE
}
For Androidx Users,
dependencies {
implementation 'androidx.multidex:multidex:2.0.1'
}
defaultConfig {
minSdkVersion 16
targetSdkVersion 28
multiDexEnabled true //ADD THIS LINE
}
Step 02:
After adding those Sync projects and before you run the project make sure to Build a project before the run. otherwise, you will get an exception.
/usr/bin/xcodebuild -version
will give you the xcode version, run it via Terminal command
Just to add to this in 2019 w Angular 8,
instead of keypress I had to use keydown
@HostListener('document:keypress', ['$event'])
to
@HostListener('document:keydown', ['$event'])
