You should do like this:
@Html.DropDownListFor(m => m.ContribType,
new SelectList(Model.ContribTypeOptions,
"ContribId", "Value"))
Where:
m => m.ContribType
is a property where the result value will be.
I used Bill Star's answer slightly modified on Solaris:
find . -mtime +2 | perl -pe 's{^}{\"};s{$}{\"}' > ~/output.file
This will put quotes around each line. I didn't use the '-l' option although it probably would help.
The file list I was going though might have '-', but not newlines. I haven't used the output file with any other commands as I want to review what was found before I just start massively deleting them via xargs.
But,if you want to store a bunch of them you could bit-shift them and store them all as one int, a little like unix file permissions/modes.
For mode 755 for instance, each digit refers to a different class of users: owner, group, public. Within each digit 4 is read, 2 is write, 1 is execute so 7 is all of them like binary 111. 5 is read and execute so 101. Make up your own encoding scheme.
I'm just writing something for storing TV schedule data from Schedules Direct and I have the binary or yes/no fields: stereo, hdtv, new, ei, close captioned, dolby, sap in Spanish, season premiere. So 7 bits, or an integer with a maximum of 127. One character really.
A C example from what I'm working on now. has() is a function that returns 1 if the 2nd string is in the first one. inp is the input string to this function. misc is an unsigned char initialized to 0.
if (has(inp,"sap='Spanish'") > 0)
misc += 1;
if (has(inp,"stereo='true'") > 0)
misc +=2;
if (has(inp,"ei='true'") > 0)
misc +=4;
if (has(inp,"closeCaptioned='true'") > 0)
misc += 8;
if (has(inp,"dolby=") > 0)
misc += 16;
if (has(inp,"new='true'") > 0)
misc += 32;
if (has(inp,"premier_finale='") > 0)
misc += 64;
if (has(inp,"hdtv='true'") > 0)
misc += 128;
So I'm storing 7 booleans in one integer with room for more.

I downloaded and extracted Crypto++ in C:\cryptopp. I used Visual Studio Express 2012 to build all the projects inside (as instructed in readme), and everything was built successfully. Then I made a test project in some other folder and added cryptolib as a dependency.
The conversion was probably not successful. The only thing that was successful was the running of VCUpgrade. The actual conversion itself failed but you don't know until you experience the errors you are seeing. For some of the details, see Visual Studio on the Crypto++ wiki.
Any ideas how to fix this?
To resolve your issues, you should download vs2010.zip
if you want static C/C++ runtime linking (/MT
or /MTd
), or vs2010-dynamic.zip
if you want dynamic C/C++ runtime linking (/MT
or /MTd
). Both fix the latent, silent failures produced by VCUpgrade.
vs2010.zip
, vs2010-dynamic.zip
and vs2005-dynamic.zip
are built from the latest GitHub sources. As of this writing (JUN 1 2016), that's effectively pre-Crypto++ 5.6.4. If you are using the ZIP files with a down level Crypto++, like 5.6.2 or 5.6.3, then you will run into minor problems.
There are two minor problems I am aware. First is a rename of bench.cpp
to bench1.cpp
. Its error is either:
C1083: Cannot open source file: 'bench1.cpp': No such file or directory
LNK2001: unresolved external symbol "void __cdecl OutputResultOperations(char const *,char const *,bool,unsigned long,double)" (?OutputResultOperations@@YAXPBD0_NKN@Z)
The fix is to either (1) open cryptest.vcxproj
in notepad, find bench1.cpp
, and then rename it to bench.cpp
. Or (2) rename bench.cpp
to bench1.cpp
on the filesystem. Please don't delete this file.
The second problem is a little trickier because its a moving target. Down level releases, like 5.6.2 or 5.6.3, are missing the latest classes available in GitHub. The missing class files include HKDF (5.6.3), RDRAND (5.6.3), RDSEED (5.6.3), ChaCha (5.6.4), BLAKE2 (5.6.4), Poly1305 (5.6.4), etc.
The fix is to remove the missing source files from the Visual Studio project files since they don't exist for the down level releases.
Another option is to add the missing class files from the latest sources, but there could be complications. For example, many of the sources subtly depend upon the latest config.h
, cpu.h
and cpu.cpp
. The "subtlety" is you won't realize you are getting an under-performing class.
An example of under-performing class is BLAKE2. config.h
adds compile time ARM-32 and ARM-64 detection. cpu.h
and cpu.cpp
adds runtime ARM instruction detection, which depends upon compile time detection. If you add BLAKE2 without the other files, then none of the detection occurs and you get a straight C/C++ implementation. You probably won't realize you are missing the NEON opportunity, which runs around 9 to 12 cycles-per-byte versus 40 cycles-per-byte or so for vanilla C/C++.
All that's needed is that the format specifiers and the types agree, and you can always cast to make that true. long
is at least 32 bits, so %lu
together with (unsigned long)k
is always correct:
uint32_t k;
printf("%lu\n", (unsigned long)k);
size_t
is trickier, which is why %zu
was added in C99. If you can't use that, then treat it just like k
(long
is the biggest type in C89, size_t
is very unlikely to be larger).
size_t sz;
printf("%zu\n", sz); /* C99 version */
printf("%lu\n", (unsigned long)sz); /* common C89 version */
If you don't get the format specifiers correct for the type you are passing, then printf
will do the equivalent of reading too much or too little memory out of the array. As long as you use explicit casts to match up types, it's portable.
If you are only looking for a refresh rate for the GOOGLEFINANCE
function, keep in mind that data delays can be up to 20 minutes (per Google Finance Disclaimer).
GoogleClock
)Here is a modified version of the refresh action, taking the data delay into consideration, to save on unproductive refresh cycles.
=GoogleClock(GOOGLEFINANCE(symbol,"datadelay"))
For example, with:
then
=GoogleClock(GOOGLEFINANCE("GOOG","datadelay"))
Results in a dynamic data-based refresh rate of:
=GoogleClock(15)
GoogleClock
)If your sheet contains a number of rows of symbols, you could add a datadelay
column for each symbol and use the lowest value, for example:
=GoogleClock(MIN(dataDelayValuesNamedRange))
Where dataDelayValuesNamedRange
is the absolute reference or named reference of the range of cells that contain the data delay values for each symbol (assuming these values are different).
GoogleClock()
The GoogleClock()
function was removed in 2014 and replaced with settings setup for refreshing sheets. At present, I have confirmed that replacement settings is only on available in Sheets from when accessed from a desktop browser, not the mobile app (I'm using Google's mobile Sheets app updated 2016-03-14).
(This part of the answer is based on, and portions copied from, Google Docs Help)
To change how often "some" Google Sheets functions update:
NOTE External data functions recalculate at the following intervals:
The references in earlier sections to the display and use of the datadelay
attribute still apply, as well as the concepts for more efficient coding of sheets.
On a positive note, the new refresh option continues to be refreshed by Google servers regardless of whether you have the sheet loaded or not. That's a positive for shared sheets for sure; even more so for Google Apps Scripts (GAS), where GAS is used in workflow code or referenced data is used as a trigger for an event.
[*] in my understanding so far (I am currently testing this)
You can get the bounding box of any element by calling getBoundingClientRect
var rect = document.getElementById("myElement").getBoundingClientRect();
That will return an object with left, top, width and height fields.
Cast the dtype
of the col to str
and you can perform vectorised slicing calling str
:
In [29]:
df['new_col'] = df['First'].astype(str).str[0]
df
Out[29]:
First Second new_col
0 123 234 1
1 22 4353 2
2 32 355 3
3 453 453 4
4 45 345 4
5 453 453 4
6 56 56 5
if you need to you can cast the dtype
back again calling astype(int)
on the column
I have been doing it this way:
.element {
overflow-y: visible;
}

following will show one table of dataset
DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = ds; // dataset
DataGridView1.DataMember = "TableName"; // table name you need to show
if you want to show multiple tables, you need to create one datatable or custom object collection out of all tables.
if two tables with same table schema
dtAll = dtOne.Copy(); // dtOne = ds.Tables[0]
dtAll.Merge(dtTwo); // dtTwo = dtOne = ds.Tables[1]
DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ; // datatable
sample code to mode all tables
DataTable dtAll = ds.Tables[0].Copy();
for (var i = 1; i < ds.Tables.Count; i++)
{
dtAll.Merge(ds.Tables[i]);
}
DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ;

The del
statement might be of use, but IIRC it isn't guaranteed to free the memory. The docs are here ... and a why it isn't released is here.
I have heard people on Linux and Unix-type systems forking a python process to do some work, getting results and then killing it.
This article has notes on the Python garbage collector, but I think lack of memory control is the downside to managed memory

Got this problem when created my classes from Database First approach. Solved in using simply Convert.DateTime(dateCausingProblem) In fact, always try to convert values before passing, It saves you from unexpected values.
It can be accomplished by swapping an HTML class. It should be less prone to glitches than removing the whole element, especially with large, image links etc.
We can also decide whether we want hover states to be triggered when scrolling with touch (touchmove) or even add a timeout to delay them.
The only significant change in our code will be using additional HTML class such as <a class='hover'></a>
on elements that implement the new behaviour.
HTML
<a class='my-link hover' href='#'>
Test
</a>
CSS
.my-link:active, // :active can be turned off to disable hover state on 'touchmove'
.my-link.hover:hover {
border: 2px dotted grey;
}
JS (with jQuery)
$('.hover').bind('touchstart', function () {
var $el;
$el = $(this);
$el.removeClass('hover');
$el.hover(null, function () {
$el.addClass('hover');
});
});

Try WindowsIdentity.GetCurrent()
. You need to add reference to System.Security.Principal
Just do delete
. This is from the SQLite documentation:
"When the WHERE is omitted from a DELETE statement and the table being deleted has no triggers, SQLite uses an optimization to erase the entire table content without having to visit each row of the table individually. This "truncate" optimization makes the delete run much faster. Prior to SQLite version 3.6.5, the truncate optimization also meant that the sqlite3_changes() and sqlite3_total_changes() interfaces and the count_changes pragma will not actually return the number of deleted rows. That problem has been fixed as of version 3.6.5."
Use like this
<a href="index.php">Index Page</a>
<a href="page2.php">Page 2</a>
git stash
is your friend.
If you have not made the commit yet, just run git stash
. This will save away all of your changes.
Switch to the branch you want the changes on and run git stash pop
.
There are lots of uses for git stash. This is certainly one of the more useful reasons.
An example:
# work on some code
git stash
git checkout correct-branch
git stash pop
Using org.apache.commons.lang3.time.DateUtils
Date pDate = new Date();
DateUtils.truncate(pDate, Calendar.DAY_OF_MONTH);
Well, your code is not reproducible so we will never know for sure, but this is what help('break')
says:
break breaks out of a for, while or repeat loop; control is transferred to the first statement outside the inner-most loop.
So yes, break
only breaks the current loop. You can also see it in action with e.g.:
for (i in 1:10)
{
for (j in 1:10)
{
for (k in 1:10)
{
cat(i," ",j," ",k,"\n")
if (k ==5) break
}
}
}
Since beta.16 the parameters are not passed as array to the transform()
method anymore but instead as individual parameters:
{{ myData | date:'fullDate':'arg1':'arg2' }}
export class DatePipe implements PipeTransform {
transform(value:any, arg1:any, arg2:any):any {
...
}

pipes now take a variable number of arguments, and not an array that contains all arguments.
if the variable is a string
bool result = string.IsNullOrEmpty(variableToTest);
if you only have an object which may or may not contain a string then
bool result = string.IsNullOrEmpty(variableToTest as string);

After all files have been added, the next step is a "git commit".
"git status" will suggest what to do: files yet to add are listed at the bottom, and once they are all done, it will suggest a commit at the top, where it explains the merge status of the current branch.
GitHub
git config --global url.ssh://[email protected]/.insteadOf https://github.com/
BitBucket
git config --global url.ssh://[email protected]/.insteadOf https://bitbucket.org/
That tells git to always use SSH instead of HTTPS when connecting to GitHub/BitBucket, so you'll authenticate by certificate by default, instead of being prompted for a password.
This is a late answer, but by looking at the source code, I noticed that when the video is fullscreen, the "mejs-container-fullscreen" class is added to the "mejs-container" element. It is thus possible to change the styling based on this class.
.mejs-container.mejs-container-fullscreen {
// This rule applies only to the container when in fullscreen
padding-top: 57%;
}
Also, if you wish to make your MediaElement video fluid using CSS, below is a great trick by Chris Coyier: http://css-tricks.com/rundown-of-handling-flexible-media/
Just add this to your CSS:
.mejs-container {
width: 100% !important;
height: auto !important;
padding-top: 57%;
}
.mejs-overlay, .mejs-poster {
width: 100% !important;
height: 100% !important;
}
.mejs-mediaelement video {
position: absolute;
top: 0; left: 0; right: 0; bottom: 0;
width: 100% !important;
height: 100% !important;
}
I hope it helps.
I believe all the existing answers contain the relevant information, but I would like to summarize.
The response object that is returned by requests
get and post operations contains two useful attributes:
response.text
- Contains str
with the response text.response.content
- Contains bytes
with the raw response content.You should choose one or other of these attributes depending on the type of response you expect.
response.text
response.content
.When writing responses to file you need to use the open function with the appropriate file write mode.
"w"
- plain write mode."wb"
- binary write mode.# Request the HTML for this web page:
response = requests.get("https://stackoverflow.com/questions/31126596/saving-response-from-requests-to-file")
with open("response.txt", "w") as f:
f.write(response.text)
# Request the profile picture of the OP:
response = requests.get("https://i.stack.imgur.com/iysmF.jpg?s=32&g=1")
with open("response.jpg", "wb") as f:
f.write(response.content)
The original code should work by using wb
and response.content
:
import requests
files = {'f': ('1.pdf', open('1.pdf', 'rb'))}
response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)
response.raise_for_status() # ensure we notice bad responses
file = open("out.xls", "wb")
file.write(response.content)
file.close()
But I would go further and use the with
context manager for open
.
import requests
with open('1.pdf', 'rb') as file:
files = {'f': ('1.pdf', file)}
response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)
response.raise_for_status() # ensure we notice bad responses
with open("out.xls", "wb") as file:
file.write(response.content)
You can use Path.GetFileName
to get the filename from the full path
private string[] pdfFiles = Directory.GetFiles("C:\\Documents", "*.pdf")
.Select(Path.GetFileName)
.ToArray();
EDIT: the solution above uses LINQ, so it requires .NET 3.5 at least. Here's a solution that works on earlier versions:
private string[] pdfFiles = GetFileNames("C:\\Documents", "*.pdf");
private static string[] GetFileNames(string path, string filter)
{
string[] files = Directory.GetFiles(path, filter);
for(int i = 0; i < files.Length; i++)
files[i] = Path.GetFileName(files[i]);
return files;
}
Return min and max value in tuple:
def side_values(num_list):
results_list = sorted(num_list)
return results_list[0], results_list[-1]
somelist = side_values([1,12,2,53,23,6,17])
print(somelist)
This is another way of tackling the problem if you have long strings (like file path names) and you only want to break the strings on certain characters (like slashes). You can insert Unicode Zero Width Space characters just before (or after) the slashes in the HTML.
Well when you are writing a c program and want the output log to stay instead of flickering away you only need to import the stdlib.h header file and type "system("PAUSE");" at the place you want the output screen to halt.Look at the example here.The following simple c program prints the product of 5 and 6 i.e 30 to the output window and halts the output window.
#include <stdio.h>
#include <stdlib.h>
int main()
{
int a,b,c;
a=5;b=6;
c=a*b;
printf("%d",c);
system("PAUSE");
return 0;
}
Hope this helped.
The best threads tutorial I know of is here:

You CAN add css clases, and any type of attributes you need to blade template, try this:
{{ Form::open(array('url' => '/', 'method' => 'PUT', 'class'=>'col-md-12')) }}
.... wathever code here
{{ Form::close() }}
If you dont want to go the blade way you can add a hidden input. This is the form Laravel does, any way:
Note: Since HTML forms only support POST and GET, PUT and DELETE methods will be spoofed by automatically adding a _method hidden field to your form. (Laravel docs)
<form class="col-md-12" action="<?php echo URL::to('/');?>/post/<?=$post->postID?>" method="POST">
<!-- Rendered blade HTML form use this hidden. Dont forget to put the form method to POST -->
<input name="_method" type="hidden" value="PUT">
<div class="form-group">
<textarea type="text" class="form-control input-lg" placeholder="Text Here" name="post"><?=$post->post?></textarea>
</div>
<div class="form-group">
<button class="btn btn-primary btn-lg btn-block" type="submit" value="Edit">Edit</button>
</div>

In your situation you got a reference to the missing symbols. But in some situations, ld will not provide error information.
If you want to expand the information provided by ld, just add the following parameters to your $(LDFLAGS)
-Wl,-V
dict.keys()
Keys and values are iterated over in an arbitrary order which is non-random, varies across Python implementations, and depends on the dictionary’s history of insertions and deletions. If keys, values and items views are iterated over with no intervening modifications to the dictionary, the order of items will directly correspond.
That's why you see the indices 0 to 7 in the first column. They are produced by enumerate
and are always in the correct order. Further you see the dict's keys 0 to 7 in the second column. They are not sorted.
this will make the powershell window to wait until you press any key:

Starting in .NET 4.5 you are able to compress a directory using System.IO.Compression
into a zip file. You have to add System.IO.Compression.FileSystem
as a reference as it is not referenced by default. Then you can write:
System.IO.Compression.ZipFile.CreateFromDirectory(dirPath, zipFile);
The only potential problem is that this assembly is not available for Windows Store Apps.
Try:

config.AppSettings.Settings.Add("configFilePath", configFilePath);
config.Save(ConfigurationSaveMode.Modified,true);
config.SaveAs(@"C:\Users\USERNAME\Documents\Visual Studio 2010\Projects\ADI2v1.4\ADI2CE2\App.config",ConfigurationSaveMode.Modified, true);

GET/PUT is idempotent PATCH can be sometimes idempotent
What is idempotent - It means if we fire the query multiple times it should not afftect the result of it.(same output.Suppose a cow is pregnant and if we breed it again then it cannot be pregnent multiple times)
get
:-simple get. Get the data from server and show it to user
{
id:1
name:parth
email:[email protected]
}
post
:-create new resource at Database. It means it adds new data. Its not idempotent.
put
:-Create new resource otherwise add to existing. Idempotent because it will update the same resource everytime and output will be the same. ex. - initial data
{
id:1
name:parth
email:[email protected]
}
{

Try Foo.instance_methods.include? :bar
You can use:
input[type=text]
{
/*Styles*/
}
Define your common style attributes inside this. and for extra style you can add a class then.
These days the location of the emulated SD card is at /storage/emulated/0
I was facing the same problem during testing on mobile devices and this trick worked for me
<a type="submit" class="btn btn-primary" data-toggle="modal" href="#myModal">Submit</a>
Change the button to anchor tag it should work, the problem occurs due to its type button as it is trying to submit so the modal disappears immediately.and also remove hide from modal hide fade give
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
Hope this would work for you .
There are many articles about writing code to import an excel file, but this is a manual/shortcut version:
If you don't need to import your Excel file programmatically using code you can do it very quickly using the menu in SQL Management Studio.
The quickest way to get your Excel file into SQL is by using the import wizard:
The next window is 'Choose a Data Source', select Excel:
In the 'Data Source' dropdown list select Microsoft Excel (this option should appear automatically if you have excel installed).
Click the 'Browse' button to select the path to the Excel file you want to import.
On the 'Specify Table Copy or Query' window:
'Select Source Tables:' choose the worksheet(s) from your Excel file and specify a destination table for each worksheet. If you don't have a table yet the wizard will very kindly create a new table that matches all the columns from your spreadsheet. Click Next.
use a maxlength attribute to your input.
<input type="text" id="phone" name="phone" maxlength="10">
See the fiddle demo here Demo
You can configure patterns to hide files and folders from the explorer and searches.
Open VS User Settings (Main menu: File > Preferences > Settings). This will open the setting screen.
Search for files:exclude
in the search at the top.
Configure the User Setting with new glob patterns as needed. In this case, add this pattern node_modules/ then click OK. The pattern syntax is powerful. You can find pattern matching details under the Search Across Files topic.

I should like to take a step back and a modern look at this 10 years old question. The classes mentioned, Date
and XMLGregorianCalendar
, are old now. I challenge the use of them and offer alternatives.
Date
was always poorly designed and is more than 20 years old. This is simple: don’t use it.XMLGregorianCalendar
is old too and has an old-fashioned design. As I understand it, it was used for producing dates and times in XML format for XML documents. Like 2009-05-07T19:05:45.678+02:00
or 2009-05-07T17:05:45.678Z
. These formats agree well enough with ISO 8601 that the classes of java.time, the modern Java date and time API, can produce them, which we prefer.For many (most?) purposes the modern replacement for a Date
will be an Instant
. An Instant
is a point in time (just as a Date
is).
Instant yourInstant = // ...
System.out.println(yourInstant);
An example output from this snippet:
2009-05-07T17:05:45.678Z
It’s the same as the latter of my example XMLGregorianCalendar
strings above. As most of you know, it comes from Instant.toString
being implicitly called by System.out.println
. With java.time, in many cases we don’t need the conversions that in the old days we made between Date
, Calendar
, XMLGregorianCalendar
and other classes (in some cases we do need conversions, though, I am showing you a couple in the next section).
Neither a Date
nor in Instant
has got a time zone nor a UTC offset. The previously accepted and still highest voted answer by Ben Noland uses the JVMs current default time zone for selecting the offset of the XMLGregorianCalendar
. To include an offset in a modern object we use an OffsetDateTime
. For example:
ZoneId zone = ZoneId.of("America/Asuncion");
OffsetDateTime dateTime = yourInstant.atZone(zone).toOffsetDateTime();
System.out.println(dateTime);
2009-05-07T13:05:45.678-04:00
Again this conforms with XML format. If you want to use the current JVM time zone setting again, set zone
to ZoneId.systemDefault()
.
There are more ways to convert Instant
to XMLGregorianCalendar
. I will present a couple, each with its pros and cons. First, just as an XMLGregorianCalendar
produces a string like 2009-05-07T17:05:45.678Z
, it can also be built from such a string:
String dateTimeString = yourInstant.toString();
XMLGregorianCalendar date2
= DatatypeFactory.newInstance().newXMLGregorianCalendar(dateTimeString);
System.out.println(date2);
2009-05-07T17:05:45.678Z
Pro: it’s short and I don’t think it gives any surprises. Con: To me it feels like a waste formatting the instant into a string and parsing it back.
ZonedDateTime dateTime = yourInstant.atZone(zone);
GregorianCalendar c = GregorianCalendar.from(dateTime);
XMLGregorianCalendar date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);
System.out.println(date2);
2009-05-07T13:05:45.678-04:00
Pro: It’s the official conversion. Controlling the offset comes naturally. Con: It goes through more steps and is therefore longer.
If you got an old-fashioned Date
object from a legacy API that you cannot afford to change just now, convert it to Instant
:
Instant i = yourDate.toInstant();
System.out.println(i);
Output is the same as before:
2009-05-07T17:05:45.678Z
If you want to control the offset, convert further to an OffsetDateTime
in the same way as above.
If you’ve got an old-fashioned Date
and absolutely need an old-fashioned XMLGregorianCalendar
, just use the answer by Ben Noland.
You could try this solution :
In your location
block when you use proxy_pass
do something like this:
location ... {
add_header yourHeaderName yourValue;
proxy_pass xxxx://xxx_my_proxy_addr_xxx;
# Now use this solution:
proxy_ignore_headers yourHeaderName // but set by proxy
# Or if above didn't work maybe this:
proxy_hide_header yourHeaderName // but set by proxy
}
I'm not sure would it be exactly what you need but try some manipulation of this method and maybe result will fit your problem.
Also you can use this combination:
proxy_hide_header headerSetByProxy;
set $sent_http_header_set_by_proxy yourValue;
I had the same problem recently and this helped me:
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="FILENAME"');
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize("PATH/TO/FILE"));
ob_clean();
flush();
readfile(PATH/TO/FILE);
exit();
I found this answer here
select @EmpID = ID from dbo.Employee
Or
set @EmpID =(select id from dbo.Employee)
Note that the select query might return more than one value or rows. so you can write a select query that must return one row.
If you would like to add more columns to one variable(MS SQL), there is an option to use table defined variable
DECLARE @sampleTable TABLE(column1 type1)
INSERT INTO @sampleTable
SELECT columnsNumberEqualInsampleTable FROM .. WHERE ..
As table type variable do not exist in Oracle and others, you would have to define it:
DECLARE TYPE type_name IS TABLE OF (column_type | variable%TYPE | table.column%TYPE [NOT NULL] INDEX BY BINARY INTEGER;
-- Then to declare a TABLE variable of this type: variable_name type_name;
-- Assigning values to a TABLE variable: variable_name(n).field_name := 'some text'
;
-- Where 'n' is the index value
<img src="images/no-record-found.png" width="50%" height="50%"/>
Your images folder and your index.html should be in same directory(follow following dir structure). it will even work after build
Directory Structure
-src
|-images
|-index.html
|-app
This is a great example of why performance matters:
Doing something as simple as a test for a string can be expensive if not done correctly.
For example, if I wanted to write a function to test if something is a string, I could do it in one of two ways:
1) const isString = str => (Object.prototype.toString.call(str) === '[object String]');
2) const isString = str => ((typeof str === 'string') || (str instanceof String));
Both of these are pretty straight forward, so what could possibly impact performance? Generally speaking, function calls can be expensive, especially if you don't know what's happening inside. In the first example, there is a function call to Object's toString method. In the second example, there are no function calls, as typeof and instanceof are operators. Operators are significantly faster than function calls.
When the performance is tested, example 1 is 79% slower than example 2!

The object used in Object.create actually forms the prototype of the new object, where as in the new Function() form the declared properties/functions do not form the prototype.
Yes, Object.create
builds an object that inherits directly from the one passed as its first argument.
With constructor functions, the newly created object inherits from the constructor's prototype, e.g.:
var o = new SomeConstructor();
In the above example, o
inherits directly from SomeConstructor.prototype
.
There's a difference here, with Object.create
you can create an object that doesn't inherit from anything, Object.create(null);
, on the other hand, if you set SomeConstructor.prototype = null;
the newly created object will inherit from Object.prototype
.
You cannot create closures with the Object.create syntax as you would with the functional syntax. This is logical given the lexical (vs block) type scope of JavaScript.
Well, you can create closures, e.g. using property descriptors argument:
var o = Object.create({inherited: 1}, {
foo: {
get: (function () { // a closure
var closured = 'foo';
return function () {
return closured+'bar';
};
})()
}
});
o.foo; // "foobar"
Note that I'm talking about the ECMAScript 5th Edition Object.create
method, not the Crockford's shim.
The method is starting to be natively implemented on latest browsers, check this compatibility table.
Here are the primary differences between using System.out
/.err
/.in
and System.console()
:
System.console()
returns null if your application is not run in a terminal (though you can handle this in your application)System.console()
provides methods for reading password without echoing charactersSystem.out
and System.err
use the default platform encoding, while the Console
class output methods use the console encodingThis latter behaviour may not be immediately obvious, but code like this can demonstrate the difference:
public class ConsoleDemo {
public static void main(String[] args) {
String[] data = { "\u250C\u2500\u2500\u2500\u2500\u2500\u2510",
"\u2502Hello\u2502",
"\u2514\u2500\u2500\u2500\u2500\u2500\u2518" };
for (String s : data) {
System.out.println(s);
}
for (String s : data) {
System.console().writer().println(s);
}
}
}
On my Windows XP which has a system encoding of windows-1252 and a default console encoding of IBM850, this code will write:
???????
?Hello?
???????
+-----+
¦Hello¦
+-----+
Note that this behaviour depends on the console encoding being set to a different encoding to the system encoding. This is the default behaviour on Windows for a bunch of historical reasons.
Calling
if (a == b)
Will work most of the time, but it's not guaranteed to always work, so do not use it.
The most proper way to compare two Integer classes for equality, assuming they are named 'a' and 'b' is to call:
if(a != null && a.equals(b)) {
System.out.println("They are equal");
}
You can also use this way which is slightly faster.
if(a != null && b != null && (a.intValue() == b.intValue())) {
System.out.println("They are equal");
}
On my machine 99 billion operations took 47 seconds using the first method, and 46 seconds using the second method. You would need to be comparing billions of values to see any difference.
Note that 'a' may be null since it's an Object. Comparing in this way will not cause a null pointer exception.
For comparing greater and less than, use
if (a != null && b!=null) {
int compareValue = a.compareTo(b);
if (compareValue > 0) {
System.out.println("a is greater than b");
} else if (compareValue < 0) {
System.out.println("b is greater than a");
} else {
System.out.println("a and b are equal");
}
} else {
System.out.println("a or b is null, cannot compare");
}
\b matches a word boundary. I think you can use ^$ for empty string.
This works just fine, but instead of
name = input('Enter name of text file: ')+'.txt'
you should use
name = raw_input('Enter name of text file: ')+'.txt'
along with
open(name,'a') or open(name,'w')
There is a new polyfill component to address this issue on github. Have a look at autofill-event. Just need to bower install it and voilà, autofill works as expected.

In order to execute multiple programs, I also needed a profiles
section:
<profiles>
<profile>
<id>traverse</id>
<activation>
<property>
<name>traverse</name>

</activation>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>

<argument>-classpath</argument>
<argument>org.dhappy.test.NeoTraverse</argument>
</arguments>
</configuration>
</plugin>
</plugins>

</profile>
</profiles>
This is then executable as:
mvn exec:exec -Ptraverse
The file is created automatically (talking about Xcode 6.3.2 here). But you won't see it, since it's in your Derived Data folder. After marking your swift class with @objc
, compile, then search for Swift.h
in your Derived Data folder. You should find the Swift header there.
I had the problem, that Xcode renamed my my-Project-Swift.h
to my_Project-Swift.h
Xcode doesn't like
"." "-"
etc. symbols. With the method above you can find the filename and import it to a Objective-C class.
It's funny I had a similar issue and didn't find anything suitable and was aware of good old Dependency Walker so in the end I wrote one myself.
This deals with .NET specifically and will show what references an assembly has (and missing) recursively. It'll also show native library dependencies.
It's free (for personal use) and available here for anyone interested: www.netdepends.com

The below css code always keep the button at the bottom of the page
position:absolute;
bottom:0;
Since you want to do it in relative positioning, you should go for margin-top:100%
position:relative;
margin-top:100%;
EDIT1: JSFiddle1
EDIT2: To place button at center of the screen,
position:relative;
left: 50%;

You can use ORDER BY
clause to sort data rows by values in columns. Something like
=QUERY(responses!A1:K; "Select C, D, E where B contains '2nd Web Design' Order By C, D")
If you’d like to order by some columns descending, others ascending, you can add desc
/asc
, ie:
=QUERY(responses!A1:K; "Select C, D, E where B contains '2nd Web Design' Order By C desc, D")
I would like to suggest an improvement to yanchenko's answer.
Instead of taking the first ip in the X_FORWARDED_FOR list, I take the first one which in not a known internal ip, as some routers don't respect the protocol, and you can see internal ips as the first value of the list.
PRIVATE_IPS_PREFIX = ('10.', '172.', '192.', )
def get_client_ip(request):
"""get the client ip from the request
"""
remote_address = request.META.get('REMOTE_ADDR')
# set the default value of the ip to be the REMOTE_ADDR if available
# else None
ip = remote_address
# try to get the first non-proxy ip (not a private ip) from the
# HTTP_X_FORWARDED_FOR
x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR')
if x_forwarded_for:
proxies = x_forwarded_for.split(',')
# remove the private ips from the beginning
while (len(proxies) > 0 and
proxies[0].startswith(PRIVATE_IPS_PREFIX)):
proxies.pop(0)
# take the first ip which is not a private one (of a proxy)
if len(proxies) > 0:
ip = proxies[0]
return ip
I hope this helps fellow Googlers who have the same problem.
async
and defer
will download the file during HTML parsing. Both will not interrupt the parser.
The script with async
attribute will be executed once it is downloaded. While the script with defer
attribute will be executed after completing the DOM parsing.
The scripts loaded with async
doesn't guarantee any order. While the scripts loaded with defer
attribute maintains the order in which they appear on the DOM.
Use <script async>
when the script does not rely on anything.
when the script depends use <script defer>
.
Best solution would be add the <script>
at the bottom of the body. There will be no issue with blocking or rendering.
I like using .slice() The first argument is the starting index and the second is the ending index. Everything in between is what you get back.
var long = "hello there! Good day to ya."
// hello there! Good day to ya.
var short = long.slice(0, 5)
// hello
Usually Header file syntax start with capital letter.I found that code written all in smaller letter
#ifndef DIAG_H
#define DIAG_H
#endif
I don't know of a better way than:
unsigned char byData[xxx];
int nLength = sizeof(byData) * 2;
char *pBuffer = new char[nLength + 1];
pBuffer[nLength] = 0;
for (int i = 0; i < sizeof(byData); i++)
{
sprintf(pBuffer[2 * i], "%02X", byData[i]);
}
You can speed it up by using a Nibble to Hex method
unsigned char byData[xxx];
const char szNibbleToHex = { "0123456789ABCDEF" };
int nLength = sizeof(byData) * 2;
char *pBuffer = new char[nLength + 1];
pBuffer[nLength] = 0;
for (int i = 0; i < sizeof(byData); i++)
{
// divide by 16
int nNibble = byData[i] >> 4;
pBuffer[2 * i] = pszNibbleToHex[nNibble];
nNibble = byData[i] & 0x0F;
pBuffer[2 * i + 1] = pszNibbleToHex[nNibble];
}
Some time ago I created module for loading modules relative to pre-defined paths.
You can use it instead of require.
irequire.prefix('controllers',join.path(__dirname,'app/master'));
var adminUsersCtrl = irequire("controllers:admin/users");
var net = irequire('net');
Maybe it will be usefull for someone..
You could also do it with PowerShell:
Get-WmiObject win32_service -filter "Name='My Service'" `
| Invoke-WmiMethod -Name Change `
-ArgumentList @($null,$null,$null,$null,$null, `
"C:\Program Files (x86)\My Service\NewName.EXE")
Or:
Set-ItemProperty -Path "HKLM:\System\CurrentControlSet\Services\My Service" `
-Name ImagePath -Value "C:\Program Files (x86)\My Service\NewName.EXE"
Assuming your page size is 20 record, and you wanna get page number 2, here is how you would do it:
SQL Server, Oracle:
SELECT * -- <-- pick any columns here from your table, if you wanna exclude the RowNumber
FROM (SELECT ROW_NUMBER OVER(ORDER BY ID DESC) RowNumber, *
FROM Reflow
WHERE ReflowProcessID = somenumber) t
WHERE RowNumber >= 20 AND RowNumber <= 40
MySQL:
SELECT *
FROM Reflow
WHERE ReflowProcessID = somenumber
ORDER BY ID DESC
LIMIT 20 OFFSET 20
Swift 5:

return true
}
})
Update
And there's your problem - you do have to click event handlers for some a
elements. In this case, the order in which you attach the handlers matters since they'll be fired in that order.
Here's a working fiddle that shows the behaviour you want.
This should be your code:
$(document).ready(function(){
$('#tabs div.tab').hide();
$('#tabs div.tab:first').show();
$('#tabs ul li:first').addClass('active');
$("div.subtab_left li.notebook a").click(function(e) {
e.stopImmediatePropagation();
alert("asdasdad");
return false;
});
$('#tabs ul li a').click(function(){
alert("Handling link click");
$('#tabs ul li').removeClass('active');
$(this).parent().addClass('active');
var currentTab = $(this).attr('href');
$('#tabs div.tab').hide();
$(currentTab).show();
return false;
});
});
Note that the order of attaching the handlers has been exchanged and e.stopImmediatePropagation()
is used to stop the other click handler from firing while return false
is used to stop the default behaviour of following the link (as well as stopping the bubbling of the event. You may find that you need to use only e.stopPropagation
).
Play around with this, if you remove the e.stopImmediatePropagation()
you'll find that the second click handler's alert will fire after the first alert. Removing the return false
will have no effect on this behaviour but will cause links to be followed by the browser.
Note
A better fix might be to ensure that the selectors return completely different sets of elements so there is no overlap but this might not always be possible in which case the solution described above might be one way to consider.
I don't see why your first code snippet would not work. What's the default action that you're seeing that you want to stop?
If you've attached other event handlers to the link, you should look into event.stopPropagation()
and event.stopImmediatePropagation()
instead. Note that return false
is equivalent to calling both event.preventDefault
and event.stopPropagation()
ref
In your second code snippet, e
is not defined. So an error would thrown at e.preventDefault()
and the next lines never execute.
In other words
$("div.subtab_left li.notebook a").click(function() {
e.preventDefault();
alert("asdasdad");
return false;
});
should be
//note the e declared in the function parameters now
$("div.subtab_left li.notebook a").click(function(e) {
e.preventDefault();
alert("asdasdad");
return false;
});
Here's a working example showing that this code indeed does work and that return false
is not really required if you only want to stop the following of a link.

pipdeptree

"The

String

in java, so it falls into that category of comparison rules.
The simplest solution might be to limit the number of characters in the HTML itself. Rails has a truncate(string, length) helper, and I'm certain that whichever backend you're using provides something similar.
Due to the cross-browser issues you're already familiar with regarding the width of select boxes, this seems to me to be the most straightforward and least error-prone option.

<option value="100">One hund...</option>
<select>
Try installing

Use backticks for system commands, which helps to store their results into Perl variables.
my $pid = 5892;
my $not = ``top -H -p $pid -n 1 | grep myprocess | wc -l`;
print "not = $not\n";
Bash can be pretty obtuse sometimes.
The following commands all return different error messages for basically the same error:
$ echo hello >
bash: syntax error near unexpected token `newline`
$ echo hello > ${NONEXISTENT}
bash: ${NONEXISTENT}: ambiguous redirect
$ echo hello > "${NONEXISTENT}"
bash: : No such file or directory
Adding quotes around the variable seems to be a good way to deal with the "ambiguous redirect" message: You tend to get a better message when you've made a typing mistake -- and when the error is due to spaces in the filename, using quotes is the fix.
Session.Abandon()
will destroy/kill the entire session.
Session.Clear()
removes/clears the session data (i.e. the keys and values from the current session) but the session will be alive.
Compare to Session.Abandon() method, Session.Clear() doesn't create the new session, it just make all variables in the session to NULL.
Session ID will remain same in both the cases, as long as the browser is not closed.
Session.RemoveAll()
It removes all keys and values from the session-state collection.
Session.Remove()
It deletes an item from the session-state collection.
Session.RemoveAt()
It deletes an item at a specified index from the session-state collection.
Session.TimeOut()
This property specifies the time-out period assigned to the Session object for the application. (the time will be specified in minutes).

String.Format
adds many options in addition to the concatenation operators, including the ability to specify the specific format of each item added into the string.
For details on what is possible, I'd recommend reading the section on MSDN titled Composite Formatting. It explains the advantage of String.Format
(as well as xxx.WriteLine
and other methods that support composite formatting) over normal concatenation operators.
It Seems the Port 80 is already in use. Try to Use some other Port which is not in use by any other application in your System.
Its unbelievable after so many answers, but I did it little differently in the end. I don't like primary key to be nullable, I want to have it as first argument and also want to insert without defining it and also it should not be var.
@Entity(tableName = "employments")
data class Employment(
@PrimaryKey(autoGenerate = true) val id: Long,
@ColumnInfo(name = "code") val code: String,
@ColumnInfo(name = "title") val name: String
){
constructor(code: String, name: String) : this(0, code, name)
}
It's not as straightforward as looks. I just run into a similar question, and here is what I got: First, a little background on wikipedia.
Next, in CSS, for paper, they have pt
, which is point, or 1/72 inch. So if you want to have the same size of image as on the monitor, first you have to know the DPI/PPI of your monitor (usually 96, as mentioned on the wikipedia article), then convert it to inches, then convert it to points (divide by 72).
But then again, the browsers have all sorts of problems with printable content, for example, if you try to use float css tags, the Gecko-based browsers will cut your images mid page, even if you use page-break-inside: avoid; on your images (see here, in the Mozilla bug tracking system).
There is (much) more about printing from a browser in this article on A List Apart.
Furthermore, you have to deal width "Shrink to Fit" in the print preview, and the various paper sizes and orientations.
So either you just figure out a good image size in inches, I mean points, (7.1" * 72 = 511.2 so width: 511pt;
would work for the letter sized paper) regardless of the pixel sizes, or go width percentage widths, and base your image widths on the paper size.
Good luck...
I come across this issue myself and I performed the steps below to reuse my ExceptionController
that is annotated with @ControllerAdvise
for Exceptions
thrown in a registered Filter.
There are obviously many ways to handle exception but, in my case, I wanted the exception to be handled by my ExceptionController
because I am stubborn and also because I don't want to copy/paste the same code (i.e. I have some processing/logging code in ExceptionController
). I would like to return the beautiful JSON
response just like the rest of the exceptions thrown not from a Filter.
{
"status": 400,
"message": "some exception thrown when executing the request"
}
Anyway, I managed to make use of my ExceptionHandler
and I had to do a little bit of extra as shown below in steps:
Steps
@ControllerAdvise
i.e. MyExceptionControllerSample code
//sample Filter, to be added in web.xml
public MyFilterThatThrowException implements Filter {
//Spring Controller annotated with @ControllerAdvise which has handlers
//for exceptions
private MyExceptionController myExceptionController;
@Override
public void destroy() {
// TODO Auto-generated method stub
}
@Override
public void init(FilterConfig arg0) throws ServletException {
//Manually get an instance of MyExceptionController
ApplicationContext ctx = WebApplicationContextUtils
.getRequiredWebApplicationContext(arg0.getServletContext());
//MyExceptionHanlder is now accessible because I loaded it manually
this.myExceptionController = ctx.getBean(MyExceptionController.class);
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse res = (HttpServletResponse) response;
try {
//code that throws exception
} catch(Exception ex) {
//MyObject is whatever the output of the below method
MyObject errorDTO = myExceptionController.handleMyException(req, ex);
//set the response object
res.setStatus(errorDTO .getStatus());
res.setContentType("application/json");
//pass down the actual obj that exception handler normally send
ObjectMapper mapper = new ObjectMapper();
PrintWriter out = res.getWriter();
out.print(mapper.writeValueAsString(errorDTO ));
out.flush();
return;
}
//proceed normally otherwise
chain.doFilter(request, response);
}
}
And now the sample Spring Controller that handles Exception
in normal cases (i.e. exceptions that are not usually thrown in Filter level, the one we want to use for exceptions thrown in a Filter)
//sample SpringController
@ControllerAdvice
public class ExceptionController extends ResponseEntityExceptionHandler {
//sample handler
@ResponseStatus(value = HttpStatus.BAD_REQUEST)
@ExceptionHandler(SQLException.class)
public @ResponseBody MyObject handleSQLException(HttpServletRequest request,
Exception ex){
ErrorDTO response = new ErrorDTO (400, "some exception thrown when "
+ "executing the request.");
return response;
}
//other handlers
}
Sharing the solution with those who wish to use ExceptionController
for Exceptions
thrown in a Filter.
What worked for me was upgrading pandas to latest version:
From Command Line do:
conda update pandas
Since the beginning, Swift has provided some facilities for making ObjC and C more Swifty, adding more with each version. Now, in Swift 3, the new "import as member" feature lets frameworks with certain styles of C API -- where you have a data type that works sort of like a class, and a bunch of global functions to work with it -- act more like Swift-native APIs. The data types import as Swift classes, their related global functions import as methods and properties on those classes, and some related things like sets of constants can become subtypes where appropriate.
In Xcode 8 / Swift 3 beta, Apple has applied this feature (along with a few others) to make the Dispatch framework much more Swifty. (And Core Graphics, too.) If you've been following the Swift open-source efforts, this isn't news, but now is the first time it's part of Xcode.
Your first step on moving any project to Swift 3 should be to open it in Xcode 8 and choose Edit > Convert > To Current Swift Syntax... in the menu. This will apply (with your review and approval) all of the changes at once needed for all the renamed APIs and other changes. (Often, a line of code is affected by more than one of these changes at once, so responding to error fix-its individually might not handle everything right.)
The result is that the common pattern for bouncing work to the background and back now looks like this:
// Move to a background thread to do some long running work
DispatchQueue.global(qos: .userInitiated).async {
let image = self.loadOrGenerateAnImage()
// Bounce back to the main thread to update the UI
DispatchQueue.main.async {
self.imageView.image = image
}
}
Note we're using .userInitiated
instead of one of the old DISPATCH_QUEUE_PRIORITY
constants. Quality of Service (QoS) specifiers were introduced in OS X 10.10 / iOS 8.0, providing a clearer way for the system to prioritize work and deprecating the old priority specifiers. See Apple's docs on background work and energy efficiency for details.
By the way, if you're keeping your own queues to organize work, the way to get one now looks like this (notice that DispatchQueueAttributes
is an OptionSet
, so you use collection-style literals to combine options):
class Foo {
let queue = DispatchQueue(label: "com.example.my-serial-queue",
attributes: [.serial, .qosUtility])
func doStuff() {
queue.async {
print("Hello World")
}
}
}
Using dispatch_after
to do work later? That's a method on queues, too, and it takes a DispatchTime
, which has operators for various numeric types so you can just add whole or fractional seconds:
DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) { // in half a second...
print("Are we there yet?")
}
You can find your way around the new Dispatch API by opening its interface in Xcode 8 -- use Open Quickly to find the Dispatch module, or put a symbol (like DispatchQueue
) in your Swift project/playground and command-click it, then brouse around the module from there. (You can find the Swift Dispatch API in Apple's spiffy new API Reference website and in-Xcode doc viewer, but it looks like the doc content from the C version hasn't moved into it just yet.)
See the Migration Guide for more tips.
Late answer here, but if you search /etc/init.d/apache2
for 'reload', you'll find something like this:
do_reload() {
if apache_conftest; then
if ! pidofproc -p $PIDFILE "$DAEMON" > /dev/null 2>&1 ; then
APACHE2_INIT_MESSAGE="Apache2 is not running"
return 2
fi
$APACHE2CTL graceful > /dev/null 2>&1
return $?
else
APACHE2_INIT_MESSAGE="The apache2$DIR_SUFFIX configtest failed. Not doing anything."
return 2
fi
}
Basically, what the answers that suggest using init.d, systemctl, etc are invoking is a thin wrapper that says:
apachectl graceful
(swallowing the output, and forwarding the exit code)This suggests that @Aruman's answer is also correct, provided you are confident there are no errors in your configuration or have already run apachctl configtest
manually.
The apache documentation also supplies the same command for a graceful restart (apachectl -k graceful
), and some more color on the behavior thereof.

Left padding String
extension similar to padding(toLength:withPad:startingAt:)
in Foundation
extension String {
func leftPadding(toLength: Int, withPad: String = " ") -> String {
guard toLength > self.characters.count else { return self }
let padding = String(repeating: withPad, count: toLength - self.characters.count)
return padding + self
}
}
Usage:
let s = String(123)
s.leftPadding(toLength: 8, withPad: "0") // "00000123"
Considering unit test is the domain of this question, highly recommend you to use monkey. This Package make you to mock test without changing your original source code. Compare to other answer, it's more "non-intrusive".
main
type AA struct {
//...
}
func (a *AA) OriginalFunc() {
//...
}
mock test
var a *AA
func NewFunc(a *AA) {
//...
}
monkey.PatchMethod(reflect.TypeOf(a), "OriginalFunc", NewFunc)
Bad side is:
Good side is:
This will search and replace all non ASCII letters:
String resultString = subjectString.replaceAll("[^\\x00-\\x7F]", "");
Maybe because other languages do this as well, so it is generally-accepted behavior. (For good reasons, as shown in the other answers)
You can resize and then use imagejpeg()
Don't pass 100 as the quality for imagejpeg() - anything over 90 is generally overkill and just gets you a bigger JPEG. For a thumbnail, try 75 and work downwards until the quality/size tradeoff is acceptable.
imagejpeg($tn, $save, 75);
Iterating over two dimensions means you'll need to check over two dimensions.
assuming you're starting with:
var myArray = [
[1,1,1,1,1],
[1,1,1,1,1],
[1,1,1,1,1]
]; //don't forget your semi-colons
You want to expand this two-dimensional array to become:
var myArray = [
[1,1,1,1,1,0,0],
[1,1,1,1,1,0,0],
[1,1,1,1,1,0,0],
[0,0,0,0,0,0,0],
[0,0,0,0,0,0,0],
[0,0,0,0,0,0,0],
];
Which means you need to understand what the difference is.
Start with the outer array:
var myArray = [
[...],
[...],
[...]
];
If you want to make this array longer, you need to check that it's the correct length, and add more inner arrays to make up the difference:
var i,
rows,
myArray;
rows = 8;
myArray = [...]; //see first example above
for (i = 0; i < rows; i += 1) {
//check if the index exists in the outer array
if (!(i in myArray)) {
//if it doesn't exist, we need another array to fill
myArray.push([]);
}
}
The next step requires iterating over every column in every array, we'll build on the original code:
var i,
j,
row,
rows,
cols,
myArray;
rows = 8;
cols = 7; //adding columns in this time
myArray = [...]; //see first example above
for (i = 0; i < rows; i += 1) {
//check if the index exists in the outer array (row)
if (!(i in myArray)) {
//if it doesn't exist, we need another array to fill
myArray[i] = [];
}
row = myArray[i];
for (j = 0; j < cols; j += 1) {
//check if the index exists in the inner array (column)
if (!(i in row)) {
//if it doesn't exist, we need to fill it with `0`
row[j] = 0;
}
}
}

Using Collections#addAll()
String[] words = {"ace","boom","crew","dog","eon"};
List<String> arrayList = new ArrayList<>();
Collections.addAll(arrayList, words);
$("#element").validate().valid()
The characters '<', and '>', are to indicate a place-holder, you should remove them to read:
php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change --username=ADMINUSERNAME
It looks like the string contains an array with a single MyStok
object in it. If you remove square brackets from both ends of the input, you should be able to deserialize the data as a single object:
MyStok myobj = JSON.Deserialize<MyStok>(sc.Substring(1, sc.Length-2));
You could also deserialize the array into a list of MyStok
objects, and take the object at index zero.
var myobjList = JSON.Deserialize<List<MyStok>>(sc);
var myObj = myobjList[0];
Defining a constructor with public or internal storage class in an inheritable concrete class Thing
effectively defines two methods:
A method (which I'll call InitializeThing
) which acts upon this
, has no return value, and can only be called from Thing
's CreateThing
and InitializeThing
methods, and subclasses' InitializeXXX
methods.
A method (which I'll call CreateThing
) which returns an object of the constructor's designated type, and essentially behaves as:
Thing CreateThing(int whatever)
{
Thing result = AllocateObject<Thing>();
Thing.initializeThing(whatever);
}
Abstract classes effectively create methods of only the first form. Conceptually, there's no reason why the two "methods" described above should need to have the same access specifiers; in practice, however, there's no way to specify their accessibility differently. Note that in terms of actual implementation, at least in .NET, CreateThing
isn't really implemented as a callable method, but instead represents a code sequence which gets inserted at a newThing = new Thing(23);
statement.
You can launch the "wc.exe" executable (comes with UnixUtils and does not need installation) run as an external process. It supports different line count methods (like unix vs mac vs windows).
The backslash (\
) is an escape character in Javascript (along with a lot of other C-like languages). This means that when Javascript encounters a backslash, it tries to escape the following character. For instance, \n
is a newline character (rather than a backslash followed by the letter n).
In order to output a literal backslash, you need to escape it. That means \\
will output a single backslash (and \\\\
will output two, and so on). The reason "aa ///\"
doesn't work is because the backslash escapes the "
(which will print a literal quote), and thus your string is not properly terminated. Similarly, "aa ///\\\"
won't work, because the last backslash again escapes the quote.
Just remember, for each backslash you want to output, you need to give Javascript two.
I am not very good with this but KeyboardEvent
=> see KeyboardEvent
is initialized with initKeyEvent
.
Here is an example for emitting event on <input type="text" />
element
document.getElementById("txbox").addEventListener("keypress", function(e) {_x000D_
alert("Event " + e.type + " emitted!\nKey / Char Code: " + e.keyCode + " / " + e.charCode);_x000D_
}, false);_x000D_
_x000D_
document.getElementById("btn").addEventListener("click", function(e) {_x000D_
var doc = document.getElementById("txbox");_x000D_
var kEvent = document.createEvent("KeyboardEvent");_x000D_
kEvent.initKeyEvent("keypress", true, true, null, false, false, false, false, 74, 74);_x000D_
doc.dispatchEvent(kEvent);_x000D_
}, false);
_x000D_
<input id="txbox" type="text" value="" />_x000D_
<input id="btn" type="button" value="CLICK TO EMIT KEYPRESS ON TEXTBOX" />
_x000D_
The bottom statement is equivalent to:
.half {
flex-grow: 0;
flex-shrink: 0;
flex-basis: 50%;
}
Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.
Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.
I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)
You could query this registry value to get the SQL version directly:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\90\Tools\ClientSetup\CurrentVersion
Alternatively you can query your instance name and then use sqlcmd with your instance name that you would like:
To see your instance name:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names
Then execute this:
SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition')
If you are using C++ you can use this code to get the registry information.

var byteCharacters = atob(response.data);
var byteNumbers = new Array(byteCharacters.length);
for (var i = 0; i < byteCharacters.length; i++) {

}
var byteArray = new Uint8Array(byteNumbers);
var file = new Blob([byteArray], { type: 'application/pdf;base64' });
var fileURL = URL.createObjectURL(file);
window.open(fileURL);
You return a base64 string from the API or another source. You can also download it.

Hi,
You can also do as like below... In this way, your both functions should call and if both functions return true then it will return true else return false.
<input type="button"
onclick="var valFunc1 = func1(); var valFunc2 = func2(); if(valFunc1 == true && valFunc2 ==true) {return true;} else{return false;}"
value="Call2Functions" />
Thank you, Vishal Patel
You can use RETURN
to stop execution of a stored procedure immediately. Quote taken from Books Online:
Exits unconditionally from a query or procedure. RETURN is immediate and complete and can be used at any point to exit from a procedure, batch, or statement block. Statements that follow RETURN are not executed.
Out of paranoia, I tried yor example and it does output the PRINTs and does stop execution immediately.
Besides the methods proposed in the other answers, since Python 3.6 you can also use Literal String Interpolation (f-strings):
>>> tup = (1,2,3)
>>> print(f'this is a tuple {tup}')
this is a tuple (1, 2, 3)
As other answers have said, the best way to do this involves making a new list - either iterate over a copy, or construct a list with only the elements you want and assign it back to the same variable. The difference between these depends on your use case, since they affect other variables for the original list differently (or, rather, the first affects them, the second doesn't).
If a copy isn't an option for some reason, you do have one other option that relies on an understanding of why modifying a list you're iterating breaks. List iteration works by keeping track of an index, incrementing it each time around the loop until it falls off the end of the list. So, if you remove at (or before) the current index, everything from that point until the end shifts one spot to the left. But the iterator doesn't know about this, and effectively skips the next element since it is now at the current index rather than the next one. However, removing things that are after the current index doesn't affect things.
This implies that if you iterate the list back to front, if you remove an item at the current index, everything to it's right shifts left - but that doesn't matter, since you've already dealt with all the elements to the right of the current position, and you're moving left - the next element to the left is unaffected by the change, and so the iterator gives you the element you expect.
TL;DR:
>>> a = list(range(5))
>>> for b in reversed(a):
if b == 3:
a.remove(b)
>>> a
[0, 1, 2, 4]
However, making a copy is usually better in terms of making your code easy to read. I only mention this possibility for sake of completeness.
For a three dimensional array you could try:
for c in array.transpose(1, 0, 2):
do_stuff(c)
See the docs on how array.transpose
works. Basically you are specifying which dimension to shift. In this case we are shifting the second dimension (e.g. columns) to the first dimension.
just hoping to be helpful to someone as old problems seem to come back every now and again and I always find good tips here.
My problem was to list in a text file all the names of the "*.txt" files in a certain directory without path and without extension from a Datastage 7.5 sequence.
The solution we used is:

Is there some way I can tell grep to print every line being read regardless of whether there's a match?
Option -C999
will do the trick in the absence of an option to display all context lines. Most other grep variants support this too. However: 1) no output is produced when no match is found and 2) this option has a negative impact on grep's efficiency: when the -C
value is large this many lines may have to be temporarily stored in memory for grep to determine which lines of context to display when a match occurs. Note that grep implementations do not load input files but rather reads a few lines or use a sliding window over the input. The "before part" of the context has to be kept in a window (memory) to output the "before" context lines later when a match is found.
A pattern such as ^|PATTERN
or PATTERN|$
or any empty-matching sub-pattern for that matter such as [^ -~]?|PATTERN
is a nice trick. However, 1) these patterns don't show non-matching lines highlighted as context and 2) this can't be used in combination with some other grep options, such as -F
and -w
for example.
So none of these approaches are satisfying to me. I'm using ugrep, and enhanced grep with option -y
to efficiently display all non-matching output as color-highlighted context lines. Other grep-like tools such as ag and ripgrep also offer a pass-through option. But ugrep is compatible with GNU/BSD grep and offers a superset of grep options like -y
and -Q
. For example, here is what option -y
shows when combined with -Q
(interactive query UI to enter patterns):
ugrep -Q -y FILE ...

You can easily use Apache File Utils. Look at function writeStringToFile
. We use this library in our projects.
What you can do is to wrap the invocation into a function of its own.
So that
foo()
def foo():
print "Hi!"
will break, but
def bar():
foo()
def foo():
print "Hi!"
bar()
will be working properly.
General rule in Python
is not that function should be defined higher in the code (as in Pascal
), but that it should be defined before its usage.
Hope that helps.
If you named your class with the keyword in Java, your program wouldn't be recognized that it had the main method.
Simply PROJECTION deals with elimination or selection of columns, while SELECTION deals with elimination or selection of rows.
When you install python for windows, there is an option to include it in the path. For python 2 this is not the default. It adds the python installation folder and script folder to the Windows path. When starting the GIT Bash command prompt, it have included it in the linux PATH variable.
If you start the python installation again, you should select the option Change python and in the next step you can "Add python.exe to Path". Next time you open GIT Bash, the path is correct.
You can additionally implement IDataErrorInfo
as follows in the view model. If you implement IDataErrorInfo
, you can do the validation in that instead of the setter of a particular property, then whenever there is a error, return an error message so that the text box which has the error gets a red box around it, indicating an error.
class ViewModel : INotifyPropertyChanged, IDataErrorInfo
{
private string m_Name = "Type Here";
public ViewModel()
{
}
public string Name
{
get
{
return m_Name;
}
set
{
if (m_Name != value)
{
m_Name = value;
OnPropertyChanged("Name");
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
protected void OnPropertyChanged(string propertyName)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
public string Error
{
get { return "...."; }
}
/// <summary>
/// Will be called for each and every property when ever its value is changed
/// </summary>
/// <param name="columnName">Name of the property whose value is changed</param>
/// <returns></returns>
public string this[string columnName]
{
get
{
return Validate(columnName);
}
}
private string Validate(string propertyName)
{
// Return error message if there is error on else return empty or null string
string validationMessage = string.Empty;
switch (propertyName)
{
case "Name": // property name
// TODO: Check validiation condition
validationMessage = "Error";
break;
}
return validationMessage;
}
}
And you have to set ValidatesOnDataErrors=True
in the XAML in order to invoke the methods of IDataErrorInfo
as follows:
<TextBox Text="{Binding Name, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}" />
Obligatory answer in Swift : NSIndexPath(forRow:row, inSection: section)

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.
Building on @Peter's solution, here's a version that declares a simple LINQ-style Permutations()
extension method that works on any IEnumerable<T>
.
Usage (on string characters example):
foreach (var permutation in "abc".Permutations())
{
Console.WriteLine(string.Join(", ", permutation));
}
Outputs:
a, b, c
a, c, b
b, a, c
b, c, a
c, b, a
c, a, b
Or on any other collection type:
foreach (var permutation in (new[] { "Apples", "Oranges", "Pears"}).Permutations())
{
Console.WriteLine(string.Join(", ", permutation));
}
Outputs:
Apples, Oranges, Pears
Apples, Pears, Oranges
Oranges, Apples, Pears
Oranges, Pears, Apples
Pears, Oranges, Apples
Pears, Apples, Oranges
using System;
using System.Collections.Generic;
using System.Linq;
public static class PermutationExtension
{
public static IEnumerable<T[]> Permutations<T>(this IEnumerable<T> source)
{
var sourceArray = source.ToArray();
var results = new List<T[]>();
Permute(sourceArray, 0, sourceArray.Length - 1, results);
return results;
}
private static void Swap<T>(ref T a, ref T b)
{
T tmp = a;
a = b;
b = tmp;
}
private static void Permute<T>(T[] elements, int recursionDepth, int maxDepth, ICollection<T[]> results)
{
if (recursionDepth == maxDepth)
{
results.Add(elements.ToArray());
return;
}
for (var i = recursionDepth; i <= maxDepth; i++)
{
Swap(ref elements[recursionDepth], ref elements[i]);
Permute(elements, recursionDepth + 1, maxDepth, results);
Swap(ref elements[recursionDepth], ref elements[i]);
}
}
}
If it's really required to access SessionFactory through @Autowire, I'd rather configure another EntityManagerFactory and then use it to configure the SessionFactory bean, like following:
@Configuration
public class SessionFactoryConfig {
@Autowired
DataSource dataSource;
@Autowired
JpaVendorAdapter jpaVendorAdapter;
@Bean
@Primary
public EntityManagerFactory entityManagerFactory() {
LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
emf.setDataSource(dataSource);
emf.setJpaVendorAdapter(jpaVendorAdapter);
emf.setPackagesToScan("com.hibernateLearning");
emf.setPersistenceUnitName("default");
emf.afterPropertiesSet();
return emf.getObject();
}
@Bean
public SessionFactory setSessionFactory(EntityManagerFactory entityManagerFactory) {
return entityManagerFactory.unwrap(SessionFactory.class);
} }
Martin's solution is very similar to mine, however how would you handle a default descriptions when the desired translation isn't found ?
Would that require an IFNULL() and another SELECT statement for each field ?
The default translation would be stored in the same table, where a flag like "isDefault" indicates wether that description is the default description in case none has been found for the current language.
Using official HTML without adding extra CSS styles and classes, it's like native support.
Just add the following code:
$.fn.dropdown = (function() {
var $bsDropdown = $.fn.dropdown;
return function(config) {
if (typeof config === 'string' && config === 'toggle') { // dropdown toggle trigged
$('.has-child-dropdown-show').removeClass('has-child-dropdown-show');
$(this).closest('.dropdown').parents('.dropdown').addClass('has-child-dropdown-show');
}
var ret = $bsDropdown.call($(this), config);
$(this).off('click.bs.dropdown'); // Turn off dropdown.js click event, it will call 'this.toggle()' internal
return ret;
}
})();
$(function() {
$('.dropdown [data-toggle="dropdown"]').on('click', function(e) {
$(this).dropdown('toggle');
e.stopPropagation();
});
$('.dropdown').on('hide.bs.dropdown', function(e) {
if ($(this).is('.has-child-dropdown-show')) {
$(this).removeClass('has-child-dropdown-show');
e.preventDefault();
}
e.stopPropagation();
});
});
Dropdown of bootstrap can be easily changed to infinite level. It's a pity that they didn't do it.
BTW, a hover version: https://github.com/dallaslu/bootstrap-4-multi-level-dropdown
Here is a perfect demo: https://jsfiddle.net/dallaslu/adky6jvs/ (works well with Bootstrap v4.4.1)
You have to use Objective C to interface with the Cocoa API, so there is no choice. Of course, you can use as much C++ as you like behind the scenes (Objective C++ makes this easy).
It is an insane language indeed, but it's also... kind of fun to use once you're a bit used to it. :-)
If you are doing it in eclipse, there are a few quick notes that if you are hovering your mouse over a class in your script, it will show a focus dialogue that says hit f2 for focus.
for computer apps, use ImageIcon. and for the path say,
ImageIcon thisImage = new ImageIcon("images/youpic.png");
specify the folder( images) then seperate with / and add the name of the pic file.
I hope this is helpful. If someone else posted it, I didn't read through. So...yea.. thought reinforcement.
All of these options work depending on your situation, but you may not see any of them work if you're using SSMS (as mentioned in some comments SSMS hides CR/LFs)

Here is a sample helper class which converts an Object and returns an Expando with all public properties of the given object.
public static class dynamicHelper
{
public static ExpandoObject convertToExpando(object obj)
{
//Get Properties Using Reflections
BindingFlags flags = BindingFlags.Public | BindingFlags.Instance;
PropertyInfo[] properties = obj.GetType().GetProperties(flags);
//Add Them to a new Expando
ExpandoObject expando = new ExpandoObject();
foreach (PropertyInfo property in properties)
{
AddProperty(expando, property.Name, property.GetValue(obj));
}
return expando;
}
public static void AddProperty(ExpandoObject expando, string propertyName, object propertyValue)
{
//Take use of the IDictionary implementation
var expandoDict = expando as IDictionary;
if (expandoDict.ContainsKey(propertyName))
expandoDict[propertyName] = propertyValue;
else
expandoDict.Add(propertyName, propertyValue);
}
}
Usage:
//Create Dynamic Object
dynamic expandoObj= dynamicHelper.convertToExpando(myObject);
//Add Custom Properties
dynamicHelper.AddProperty(expandoObj, "dynamicKey", "Some Value");

You can use String.Format:
DateTime d = DateTime.Now;
string str = String.Format("{0:00}/{1:00}/{2:0000} {3:00}:{4:00}:{5:00}.{6:000}", d.Month, d.Day, d.Year, d.Hour, d.Minute, d.Second, d.Millisecond);
// I got this result: "02/23/2015 16:42:38.234"
Although there is nothing wrong with the other solutions presented, you could simplify and greatly escalate your solutions by using python's excellent library pandas.
Pandas is a library for handling data in Python, preferred by many Data Scientists.
Pandas has a simplified CSV interface to read and parse files, that can be used to return a list of dictionaries, each containing a single line of the file. The keys will be the column names, and the values will be the ones in each cell.
In your case:
import pandas
def create_dictionary(filename):
my_data = pandas.DataFrame.from_csv(filename, sep='\t', index_col=False)
# Here you can delete the dataframe columns you don't want!
del my_data['B']
del my_data['D']
# ...
# Now you transform the DataFrame to a list of dictionaries
list_of_dicts = [item for item in my_data.T.to_dict().values()]
return list_of_dicts
# Usage:
x = create_dictionary("myfile.csv")
From http://docs.python-requests.org/en/latest/user/quickstart/
url = 'https://api.github.com/some/endpoint'
payload = {'some': 'data'}
headers = {'content-type': 'application/json'}
r = requests.post(url, data=json.dumps(payload), headers=headers)
You just need to create a dict with your headers (key: value pairs where the key is the name of the header and the value is, well, the value of the pair) and pass that dict to the headers parameter on the .get
or .post
method.
So more specific to your question:
headers = {'foobar': 'raboof'}
requests.get('http://himom.com', headers=headers)
Transferring a file using TortoiseSVN:
Step:1 Please Select the files which you want to move, Right-click and drag the files to the folder which you to move them to, A window will popup after follow the below instruction
Step 2: After you click the above the commit the file as below mention
You can use SUBSTRING(locations
.raw
,-6,4) for where conditon
SELECT `users`.`first_name`, `users`.`last_name`, `users`.`email`,
SUBSTRING(`locations`.`raw`,-6,4) AS `guaranteed_postcode`
FROM `users` LEFT OUTER JOIN `locations`
ON `users`.`id` = `locations`.`user_id`
WHERE SUBSTRING(`locations`.`raw`,-6,4) NOT IN #this is where the fake col is being used
(
SELECT `postcode` FROM `postcodes` WHERE `region` IN
(
'australia'
)
)
Here the code to use your app.js
input specifies file name
res.download(__dirname+'/'+input);
Can also be done this way:
this.users = this.users.filter((item) => {
return (item.name.toString().toLowerCase().indexOf(val.toLowerCase()) > -1 ||
item.address.toLowerCase().indexOf(val.toLowerCase()) > -1 ||
item.age.toLowerCase().indexOf(val.toLowerCase()) > -1 ||
item.email.toLowerCase().indexOf(val.toLowerCase()) > -1);
})
(Posted on behalf of the OP).
I believe I figured it out.
In my case, I added [class*="col-"] {padding: 0 7.5px;};
.
Then added .row {margin: 0 -7.5px;}
.
This works pretty well, except there is 1px margin on both sides. So I just make .row {margin: 0 -7.5px;}
to .row {margin: 0 -8.5px;}
, then it works perfectly.
I have no idea why there is a 1px margin. Maybe someone can explain it?
See the sample I created:
First of all, it is a bad design, if you need something like that, it is good idea to refactor, e.g. by renaming the method. Java allows calling of overriden method using the "super" keyword, but only one level up in the hierarchy, I am not sure, maybe Scala and some other JVM languages support it for any level.
A good rule of thumb when constructing arguments for use in conditional statements (IF, WHILE, etc.) is to always use the &&/|| forms, unless there's a very good reason not to. There are two reasons...
Doing this, rather than relying on MATLAB's resolution of vectors in & and |, leads to code that's a little bit more verbose, but a LOT safer and easier to maintain.
If you just want the button to have different styling while the mouse is pressed you can use the :active
pseudo class.
.button:active {
}
If on the other hand you want the style to stay after clicking you will have to use javascript.
Laravel use array for Form::select
. So I passed array like below:
$datas = Items::lists('name', 'id');
$items = array();
foreach ($datas as $data)
{
$items[$data->id] = $data->name;
}
return \View::make('your view', compact('items',$items));
In your view:
<div class="form-group">
{!! Form::label('item', 'Item:') !!}
{!! Form::select('item_id', $items, null, ['class' => 'form-control']) !!}
</div>
Checking if something is promise unnecessarily complicates the code, just use Promise.resolve
Promise.resolve(valueOrPromiseItDoesntMatter).then(function(value) {
})
Scott Gu's quoted blog post explains it nicely.
For me, the answer to the question is in the following statement in that post:
Note how the static method above has a "this" keyword before the first parameter argument of type string. This tells the compiler that this particular Extension Method should be added to objects of type "string". Within the IsValidEmailAddress() method implementation I can then access all of the public properties/methods/events of the actual string instance that the method is being called on, and return true/false depending on whether it is a valid email or not.
I have summarized my favorites to try out:
https://repl.it/@SmaMa/Python-List-of-unique-dictionaries
# ----------------------------------------------
# Setup
# ----------------------------------------------
myList = [
{"id":"1", "lala": "value_1"},
{"id": "2", "lala": "value_2"},
{"id": "2", "lala": "value_2"},
{"id": "3", "lala": "value_3"}
]
print("myList:", myList)
# -----------------------------------------------
# Option 1 if objects has an unique identifier
# -----------------------------------------------
myUniqueList = list({myObject['id']:myObject for myObject in myList}.values())
print("myUniqueList:", myUniqueList)
# -----------------------------------------------
# Option 2 if uniquely identified by whole object
# -----------------------------------------------
myUniqueSet = [dict(s) for s in set(frozenset(myObject.items()) for myObject in myList)]
print("myUniqueSet:", myUniqueSet)
# -----------------------------------------------
# Option 3 for hashable objects (not dicts)
# -----------------------------------------------
myHashableObjects = list(set(["1", "2", "2", "3"]))
print("myHashAbleList:", myHashableObjects)

I've ran into the same problem. The question here is that play-java-jpa artifact (javaJpa key in the build.sbt file) depends on a different version of the spec (version 2.0 -> "org.hibernate.javax.persistence" % "hibernate-jpa-2.0-api" % "1.0.1.Final")
.
When you added hibernate-entitymanager 4.3 this brought the newer spec (2.1) and a different factory provider for the entitymanager. Basically you ended up having both jars in the classpath as transitive dependencies.
Edit your build.sbt file like this and it will temporarily fix you problem until play releases a new version of the jpa plugin for the newer api dependency.
libraryDependencies ++= Seq(
javaJdbc,
javaJpa.exclude("org.hibernate.javax.persistence", "hibernate-jpa-2.0-api"),
"org.hibernate" % "hibernate-entitymanager" % "4.3.0.Final"
)
This is for play 2.2.x
. In previous versions there were some differences in the build files.
Just use glob('*')
. Here's Documentation
Remove the name
param from the class declaration. The init method is used to pass arguments to a class at creation.
class Person(object):
def __init__(self, name):
self.name = name
me = Person("TheLazyScripter")
print me.name
You'll first require to close the file using fclose($handle);
it's not deleting because the file is in use. So first close the file and then try.
I think you should append .value in IF statement:
If Cells(i, "A").Value <> "Miami" And Cells(i, "D").Value <> "Florida" Then
Cells(i, "C").Value = "BA"
End IF
You can add the tag as a property for the Fragment
arguments. It will be automatically restored if the fragment is destroyed and then recreated by the OS.
Example:-
final Bundle args = new Bundle();
args.putString("TAG", "my tag");
fragment.setArguments(args);
This is because, by default, Jaxb when serializes a pojo, looks for the annotations over the public members(getters or setters) of the properties. But, you are providing annotations on fields. so, either change and set the annotations on setters or getters of properties, or sets the XmlAccessortype to field.
Option 1::
@XmlRootElement(name = "fields")
@XmlAccessorType(XmlAccessType.FIELD)
public class Fields {
@XmlElement(name = "field")
List<Field> fields = new ArrayList<Field>();
//getter, setter
}
@XmlAccessorType(XmlAccessType.FIELD)
public class Field {
@XmlAttribute(name = "mappedField")
String mappedField;
//getter,setter
}
Option 2::
@XmlRootElement(name = "fields")
public class Fields {
List<Field> fields = new ArrayList<Field>();
@XmlElement(name = "field")
public List<Field> getFields() {
}
//setter
}
@XmlAccessorType(XmlAccessType.FIELD)
public class Field {
String mappedField;
@XmlAttribute(name = "mappedField")
public String getMappedField() {
}
//setter
}
For more detail and depth, check the following JDK documentation http://docs.oracle.com/javase/6/docs/api/javax/xml/bind/annotation/XmlAccessorType.html
Although it may seem annoying (coming from C) that Java did not include unsigned byte in the language it really is no big deal since a simple "b & 0xFF" operation yields the unsigned value for (signed) byte b in the (rare) situations that it is actually needed. The bits don't actually change -- just the interpretation (which is important only when doing for example some math operations on the values).
dancavallaro has it right, %*
for all command line parameters (excluding the script name itself). You might also find these useful:
%0
- the command used to call the batch file (could be foo
, ..\foo
, c:\bats\foo.bat
, etc.)
%1
is the first command line parameter,
%2
is the second command line parameter,
and so on till %9
(and SHIFT
can be used for those after the 9th).
%~nx0
- the actual name of the batch file, regardless of calling method (some-batch.bat)
%~dp0
- drive and path to the script (d:\scripts)
%~dpnx0
- is the fully qualified path name of the script (d:\scripts\some-batch.bat)

check Robocopy:
ROBOCOPY \\server-source\c$\VMExports\ C:\VMExports\ /E /COPY:DAT
make sure you check what robocopy parameter you want. this is just an example.
type robocopy /?

You need to do one of these two options:
between
condition: ... where created_at between '2013-05-01 00:00:00' and '2013-05-01 23:59:59'
(not recommended... see the last paragraph)between
. Notice that then you'll have to add one day to the second value: ... where (created_at >= '2013-05-01' and created_at < '2013-05-02')
My personal preference is the second option. Also, Aaron Bertrand has a very clear explanation on why it should be used.
A tty
is a physical terminal-teletype port on a computer (usually a serial port).
The word teletype is a shorting of the telegraph typewriter, or teletypewriter device from the 1930s - itself an electromagnetic device which replaced the telegraph encoding machines of the 1830s and 1840s.
A pty
is a pseudo-teletype port provided by a computer Operating System Kernel to connect software programs emulating terminals, such as ssh, xterm, or screen.
A terminal is simply a computer's user interface that uses text for input and output.
These use pseudo-teletype ports however, their naming and implementations have diverged a little.
Linux mounts a special file system devpts on /dev (the 's' presumably standing for serial) that creates a corresponding entry in /dev/pts
for every new terminal window you open, e.g. /dev/pts/0
macOS/FreeBSD also use the /dev file structure however, they use a numbered TTY
naming convention ttys
for every new terminal window you open e.g. /dev/ttys002
Microsoft Windows still has the concept of an LPT
port for Line Printer Terminals within it's Command Shell for output to a printer.
Eclipse has an option to format automatically when saving the file. There is no option for this in IntelliJ although you can configure a macro for the Ctrl+S (Cmd+S on Mac) keys to format the code and save it.
If you want to use it with groups, you can use:

Note that you can build your own cross-platform library in python using conditional imports. e.g.
import platform
if platform.system() == 'Linux':
import LinuxMac
mac_address = LinuxMac.get_mac_address()
elif platform.system() == 'Windows':
# etc
This will allow you to use os.system calls or platform-specific libraries.
Lapack is a Linear Algebra package which is used by R (actually it's used everywhere) underneath solve()
, dgesv spits this kind of error when the matrix you passed as a parameter is singular.
As an addendum: dgesv performs LU decomposition, which, when using your matrix, forces a division by 0, since this is ill-defined, it throws this error. This only happens when matrix is singular or when it's singular on your machine (due to approximation you can have a really small number be considered 0)
I'd suggest you check its determinant if the matrix you're using contains mostly integers and is not big. If it's big, then take a look at this link.

Here the solution for my case ( private repos, free account plan)
The image build name to push has to have the same name of the repos.
Example: repos on docker hub is: accountName/resposName image build name "accountName/resposName" -> docker build -t accountName/resposName
then type docker push accountName/resposName:latest
That's all.
If you push it out through MDM it should auto-trust the application (https://support.apple.com/en-gb/HT204460), but it still has to verify the certs etc with Apple to ensure they've not been revoked etc i presume. I had this message preventing the application from launching and it was only when the proxy information was configured so it i could use the internet that it went away after a couple more launch attempts.
