Try adding LD_LIBRARY_PATH
, which indicates search paths, to your ~/.bashrc
file
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path_to_your_library
It works!
You can change location of legend using loc argument. https://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.legend
import matplotlib.pyplot as plt
plt.subplot(211)
plt.plot([1,2,3], label="test1")
plt.plot([3,2,1], label="test2")
# Place a legend above this subplot, expanding itself to
# fully use the given bounding box.
plt.legend(bbox_to_anchor=(0., 1.02, 1., .102), loc=3,
ncol=2, mode="expand", borderaxespad=0.)
plt.subplot(223)
plt.plot([1,2,3], label="test1")
plt.plot([3,2,1], label="test2")
# Place a legend to the right of this smaller subplot.
plt.legend(bbox_to_anchor=(1.05, 1), loc=2, borderaxespad=0.)
plt.show()
Assuming Unix file type and you only want the last newline this works.
sed -e '${/^$/d}'
It will not work on multiple newlines...
* Works only if the last line is a blank line.
A Context
is:
Since $.getJSON
is async, I think your console.log(list.length);
code is firing before your array has been populated. To correct this put your console.log
statement inside your callback:
var list = new Array();
$.getJSON("json.js", function(data) {
$.each(data, function(i, item) {
console.log(item.text);
list.push(item.text);
});
console.log(list.length);
});
The packages you installed introduced dependencies to version 5.2.3.0 dll's as user Bracher showed above. Microsoft.AspNet.WebApi.Cors is an example package. The path I take is to update the MVC project proir to any package installs:
Install-Package Microsoft.AspNet.Mvc -Version 5.2.3
This will give you the contents of a file separated, line-by-line in a list:
with open('xyz.txt') as f_obj:
f_obj.readlines()
You would use the WITH ADMIN OPTION
option in the GRANT
statement
GRANT CREATE SESSION TO <<username>> WITH ADMIN OPTION
After trying to get this to work for too many hours, I finally found this: https://github.com/vierno/django-xhtml2pdf
It's a fork of https://github.com/chrisglass/django-xhtml2pdf that provides a mixin for a generic class-based view. I used it like this:
# views.py
from django_xhtml2pdf.views import PdfMixin
class GroupPDFGenerate(PdfMixin, DetailView):
model = PeerGroupSignIn
template_name = 'groups/pdf.html'
# templates/groups/pdf.html
<html>
<style>
@page { your xhtml2pdf pisa PDF parameters }
</style>
</head>
<body>
<div id="header_content"> (this is defined in the style section)
<h1>{{ peergroupsignin.this_group_title }}</h1>
...
Use the model name you defined in your view in all lowercase when populating the template fields. Because its a GCBV, you can just call it as '.as_view' in your urls.py:
# urls.py (using url namespaces defined in the main urls.py file)
url(
regex=r"^(?P<pk>\d+)/generate_pdf/$",
view=views.GroupPDFGenerate.as_view(),
name="generate_pdf",
),
Ran into a similar problem with VS not discovering test methods. In my case I had the static keyword with the method, which I removed and it worked.
[TestMethod]
Before: public static void Test1()
After: public void Test1()
Either you can use RAW SQL:
INSERT INTO DEST_TABLE (Field1, Field2)
SELECT Source_Field1, Source_Field2
FROM SOURCE_TABLE
Or use the wizard:
Then execute:
TRUNCATE TABLE SOURCE_TABLE
We have been solving the same problem just today, and all you need to do is to increase the runtime version of .NET
4.5.2 didn't work for us with the above problem, while 4.6.1 was OK
If you need to keep the .NET version, then set
ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;
The reason is because varargs give the option of being called with a non-parametrized object array. So if your type was List < A > ... , it can also be called with List[] non-varargs type.
Here is an example:
public static void testCode(){
List[] b = new List[1];
test(b);
}
@SafeVarargs
public static void test(List<A>... a){
}
As you can see List[] b can contain any type of consumer, and yet this code compiles. If you use varargs, then you are fine, but if you use the method definition after type-erasure - void test(List[]) - then the compiler will not check the template parameter types. @SafeVarargs will suppress this warning.
Oracle has a page for this issue with SQL and trouble shooting suggestions.
"Troubleshooting Open Cursor Issues" http://docs.oracle.com/cd/E40329_01/admin.1112/e27149/cursor.htm#OMADM5352
You likely have other files (such as the default
configuration) located in /etc/nginx/sites-enabled
that needs to be removed.
This issue is caused by a repeat of the default_server
parameter supplied to one or more listen
directives in your files. You'll likely find this conflicting directive reads something similar to:
listen 80 default_server;
As the nginx core module documentation for listen
states:
The
default_server
parameter, if present, will cause the server to become the default server for the specifiedaddress:port
pair. If none of the directives have thedefault_server
parameter then the first server with theaddress:port
pair will be the default server for this pair.
This means that there must be another file or server
block defined in your configuration with default_server
set for port 80. nginx is encountering that first before your mysite.com
file so try removing or adjusting that other configuration.
If you are struggling to find where these directives and parameters are set, try a search like so:
grep -R default_server /etc/nginx
Unix and Windows both have things called "Named pipes", but they behave differently. On Unix, a named pipe is a one-way street which typically has just one reader and one writer - the writer writes, and the reader reads, you get it?
On Windows, the thing called a "Named pipe" is an IPC object more like a TCP socket - things can flow both ways and there is some metadata (You can obtain the credentials of the thing on the other end etc).
Unix named pipes appear as a special file in the filesystem and can be accessed with normal file IO commands including the shell. Windows ones don't, and need to be opened with a special system call (after which they behave mostly like a normal win32 handle).
Even more confusing, Unix has something called a "Unix socket" or AF_UNIX socket, which works more like (but not completely like) a win32 "named pipe", being bidirectional.
OK turns out what you really want is this: http://inputsimulator.codeplex.com/
Which has done all the hard work of exposing the Win32 SendInput
methods to C#. This allows you to directly send the windows key. This is tested and works:
InputSimulator.SimulateModifiedKeyStroke(VirtualKeyCode.LWIN, VirtualKeyCode.VK_E);
Note however that in some cases you want to specifically send the key to the application (such as ALT+F4
), in which case use the Form
library method. In others, you want to send it to the OS in general, use the above.
Old
Keeping this here for reference, it will not work in all operating systems, and will not always behave how you want. Note that you're trying to send these key strokes to the app, and the OS usually intercepts them early. In the case of Windows 7 and Vista, too early (before the E
is sent).
SendWait("^({ESC}E)")
or Send("^({ESC}E)")
Note from here: http://msdn.microsoft.com/en-us/library/system.windows.forms.sendkeys.aspx
To specify that any combination of SHIFT, CTRL, and ALT should be held down while several other keys are pressed, enclose the code for those keys in parentheses. For example, to specify to hold down SHIFT while E and C are pressed, use "+(EC)". To specify to hold down SHIFT while E is pressed, followed by C without SHIFT, use "+EC".
Note that since you want ESC
and (say) E
pressed at the same time, you need to enclose them in brackets.
I look for good answer for this... and I found this:
First delete the 'no file chosen'
input[type="file"]{
font-size: 0px;
}
then work the button with the -webkit-file-upload-button
, this way:
input[type="file"]::-webkit-file-input-button{
font-size: 16px; /*normal size*/
}
hope this is what you were looking for, it works for me.

I had the exact same error message
Error running android: Gradle project sync failed. Please fix your project and try again
, but if none of the above fixes your error, then I would highly suggest for you to check your syntax inside the AndroidManifest.xml file.
That fixed if for me. I don't understand why the error-message is so misleading, since it had nothing to do with the build gradle directly.
Please also see this SO-answer here, which has lead many of us in the right direction.
you need to do:
let fileUrl = URL(string: filePath)
or
let fileUrl = URL(fileURLWithPath: filePath)
depending on your needs. See URL docs
Before Swift 3, URL was called NSURL.
Try this
SELECT * FROM messages where id in (SELECT max(id) FROM messages GROUP BY from_id ) order by id desc
DiskFileUpload upload=new DiskFileUpload();
From this object you have to get file items and fields then yo can store into server like followed:
String loc="./webapps/prjct name/server folder/"+contentid+extension;
File uploadFile=new File(loc);
item.write(uploadFile);

Don't pass db models directly to your views. You're lucky enough to be using MVC, so encapsulate using view models.
Create a view model class like this:
public class EmployeeAddViewModel
{
public Employee employee { get; set; }
public Dictionary<int, string> staffTypes { get; set; }
// really? a 1-to-many for genders
public Dictionary<int, string> genderTypes { get; set; }
public EmployeeAddViewModel() { }
public EmployeeAddViewModel(int id)
{
employee = someEntityContext.Employees
.Where(e => e.ID == id).SingleOrDefault();
// instantiate your dictionaries
foreach(var staffType in someEntityContext.StaffTypes)
{
staffTypes.Add(staffType.ID, staffType.Type);
}
// repeat similar loop for gender types
}
}
Controller:
[HttpGet]
public ActionResult Add()
{
return View(new EmployeeAddViewModel());
}
[HttpPost]
public ActionResult Add(EmployeeAddViewModel vm)
{
if(ModelState.IsValid)
{
Employee.Add(vm.Employee);
return View("Index"); // or wherever you go after successful add
}
return View(vm);
}
Then, finally in your view (which you can use Visual Studio to scaffold it first), change the inherited type to ShadowVenue.Models.EmployeeAddViewModel. Also, where the drop down lists go, use:
@Html.DropDownListFor(model => model.employee.staffTypeID,
new SelectList(model.staffTypes, "ID", "Type"))
and similarly for the gender dropdown
@Html.DropDownListFor(model => model.employee.genderID,
new SelectList(model.genderTypes, "ID", "Gender"))
Update per comments
For gender, you could also do this if you can be without the genderTypes in the above suggested view model (though, on second thought, maybe I'd generate this server side in the view model as IEnumerable). So, in place of new SelectList...
below, you would use your IEnumerable.
@Html.DropDownListFor(model => model.employee.genderID,
new SelectList(new SelectList()
{
new { ID = 1, Gender = "Male" },
new { ID = 2, Gender = "Female" }
}, "ID", "Gender"))
Finally, another option is a Lookup table. Basically, you keep key-value pairs associated with a Lookup type. One example of a type may be gender, while another may be State, etc. I like to structure mine like this:
ID | LookupType | LookupKey | LookupValue | LookupDescription | Active
1 | Gender | 1 | Male | male gender | 1
2 | State | 50 | Hawaii | 50th state | 1
3 | Gender | 2 | Female | female gender | 1
4 | State | 49 | Alaska | 49th state | 1
5 | OrderType | 1 | Web | online order | 1
I like to use these tables when a set of data doesn't change very often, but still needs to be enumerated from time to time.
Hope this helps!
Here is PySpark version to create Hive table from parquet file. You may have generated Parquet files using inferred schema and now want to push definition to Hive metastore. You can also push definition to the system like AWS Glue or AWS Athena and not just to Hive metastore. Here I am using spark.sql to push/create permanent table.
# Location where my parquet files are present.
df = spark.read.parquet("s3://my-location/data/")
cols = df.dtypes
buf = []
buf.append('CREATE EXTERNAL TABLE test123 (')
keyanddatatypes = df.dtypes
sizeof = len(df.dtypes)
print ("size----------",sizeof)
count=1;
for eachvalue in keyanddatatypes:
print count,sizeof,eachvalue
if count == sizeof:
total = str(eachvalue[0])+str(' ')+str(eachvalue[1])
else:
total = str(eachvalue[0]) + str(' ') + str(eachvalue[1]) + str(',')
buf.append(total)
count = count + 1
buf.append(' )')
buf.append(' STORED as parquet ')
buf.append("LOCATION")
buf.append("'")
buf.append('s3://my-location/data/')
buf.append("'")
buf.append("'")
##partition by pt
tabledef = ''.join(buf)
print "---------print definition ---------"
print tabledef
## create a table using spark.sql. Assuming you are using spark 2.1+
spark.sql(tabledef);

I've had the same problem and determined that this issue arises because SQL Server does not perform comparisons on characters converted to integers in an identical manner. In my test, I've found that some comparisons of converted characters, such as the exclamation point, will return type conversion errors, while other comparisons of converted characters, such as the space, will be determined to be out of range.
This sample code tests the different possible scenarios and presents a solution using nested REPLACE statements. The REPLACE determines if there are any characters in the string that are not numerals or the slash, and, if any exist, the length of the string will be greater than zero, thereby indicating that there are 'bad' characters and the date is invalid.
DECLARE @str varchar(10)
SET @str = '12/10/2012'
IF convert(int, substring(@str,4,2)) <= 31 AND convert(int, substring(@str,4,2)) >= 1
PRINT @str+': Passed Test'
ELSE PRINT @str+': Failed Test'
GO
DECLARE @str varchar(10)
SET @str = '12/10/2012'
PRINT 'Number of characters in ' + @str + ' that are not numerals or a slash (0 means the date is valid; all values greater than 0 indicate a problem): ' + convert(varchar(5),len(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(replace(@str,'0',''),'1',''),'2',''),'3',''),'4',''),'5',''),'6',''),'7',''), '8',''),'9',''),'/',''),' ','+'))) --replace space with a + to avoid empty string
PRINT ''
GO
DECLARE @str varchar(10)

While the currently accepted answer was a huge help to me, I wanted to share some useful modifications that simplify the queries and also increase performance.
To handle events which recur at regular intervals, such as:
Repeat every other day
or
Repeat every week on Tuesday
You should create two tables, one called events
like this:
ID NAME
1 Sample Event
2 Another Event
And a table called events_meta
like this:
ID event_id repeat_start repeat_interval
1 1 1369008000 604800 -- Repeats every Monday after May 20th 2013
1 1 1369008000 604800 -- Also repeats every Friday after May 20th 2013
With repeat_start
being a unix timestamp date with no time (1369008000 corresponds to May 20th 2013) , and repeat_interval
an amount in seconds between intervals (604800 is 7 days).
By looping over each day in the calendar you can get repeat events using this simple query:
SELECT EV.*
FROM `events` EV
RIGHT JOIN `events_meta` EM1 ON EM1.`event_id` = EV.`id`
WHERE (( 1299736800 - repeat_start) % repeat_interval = 0 )
Just substitute in the unix-timestamp (1299736800) for each date in your calendar.
Note the use of the modulo (% sign). This symbol is like regular division, but returns the ''remainder'' instead of the quotient, and as such is 0 whenever the current date is an exact multiple of the repeat_interval from the repeat_start.
This is significantly faster than the previously suggested "meta_keys"-based answer, which was as follows:
SELECT EV.*
FROM `events` EV
RIGHT JOIN `events_meta` EM1 ON EM1.`event_id` = EV.`id`
RIGHT JOIN `events_meta` EM2 ON EM2.`meta_key` = CONCAT( 'repeat_interval_', EM1.`id` )
WHERE EM1.meta_key = 'repeat_start'
AND (
( CASE ( 1299132000 - EM1.`meta_value` )
WHEN 0
THEN 1
ELSE ( 1299132000 - EM1.`meta_value` )
END
) / EM2.`meta_value`
) = 1
If you run EXPLAIN this query, you'll note that it required the use of a join buffer:
+----+-------------+-------+--------+---------------+---------+---------+------------------+------+--------------------------------+
| id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
+----+-------------+-------+--------+---------------+---------+---------+------------------+------+--------------------------------+
| 1 | SIMPLE | EM1 | ALL | NULL | NULL | NULL | NULL | 2 | Using where |
| 1 | SIMPLE | EV | eq_ref | PRIMARY | PRIMARY | 4 | bcs.EM1.event_id | 1 | |
| 1 | SIMPLE | EM2 | ALL | NULL | NULL | NULL | NULL | 2 | Using where; Using join buffer |
+----+-------------+-------+--------+---------------+---------+---------+------------------+------+--------------------------------+
The solution with 1 join above requires no such buffer.
You can add support for more complex types to support these types of repeat rules:
Event A repeats every month on the 3rd of the month starting on March 3, 2011
or
Event A repeats second Friday of the month starting on March 11, 2011
Your events table can look exactly the same:
ID NAME
1 Sample Event
2 Another Event
Then to add support for these complex rules add columns to events_meta
like so:
ID event_id repeat_start repeat_interval repeat_year repeat_month repeat_day repeat_week repeat_weekday
1 1 1369008000 604800 NULL NULL NULL NULL NULL -- Repeats every Monday after May 20, 2013
1 1 1368144000 604800 NULL NULL NULL NULL NULL -- Repeats every Friday after May 10, 2013
2 2 1369008000 NULL 2013 * * 2 5 -- Repeats on Friday of the 2nd week in every month
Note that you simply need to either specify a repeat_interval
or a set of repeat_year
, repeat_month
, repeat_day
, repeat_week
, and repeat_weekday
data.
This makes selection of both types simultaneously very simple. Just loop through each day and fill in the correct values, (1370563200 for June 7th 2013, and then the year, month, day, week number and weekday as follows):
SELECT EV.*
FROM `events` EV
RIGHT JOIN `events_meta` EM1 ON EM1.`event_id` = EV.`id`
WHERE (( 1370563200 - repeat_start) % repeat_interval = 0 )
OR (
(repeat_year = 2013 OR repeat_year = '*' )
AND
(repeat_month = 6 OR repeat_month = '*' )
AND
(repeat_day = 7 OR repeat_day = '*' )
AND
(repeat_week = 2 OR repeat_week = '*' )
AND
(repeat_weekday = 5 OR repeat_weekday = '*' )
AND repeat_start <= 1370563200
)
This returns all events that repeat on the Friday of the 2nd week, as well as any events that repeat every Friday, so it returns both event ID 1 and 2:
ID NAME
1 Sample Event
2 Another Event
*Sidenote in the above SQL I used PHP Date's default weekday indexes, so "5" for Friday
Hope this helps others as much as the original answer helped me!
The only way to access those methods is through reflection. You can get a handle on a PackageManager
object by calling getApplicationContext().getPackageManager()
and using reflection access these methods. Checkout this tutorial.
If you are using the grid or alike component: In XAML, make sure that the elements in the grid have Grid.Row and Grid.Column defined, and ensure tha they don't have margins. If you used designer mode, or Expression Blend, it could have assigned margins relative to the whole grid instead of to particular cells. As for cell sizing, I add an extra cell that fills up the rest of the space:
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
One approach is to combine the search strings into a regex pattern as in this answer.
After way too much research, trial and error I found a way that seems to works fine and doesn't require to manually re-set the font size manually on the children elements, allowing me to have a standardized em font size across the whole doc.
In Firefox this is fairly simple, just set word-spacing: -1em
on the parent element. For some reason, Chrome ignore this (and as far as I tested, it ignores the word spacing regardless of the value). So besides this I add letter-spacing: -.31em
to the parent and letter-spacing: normal
to the children. This fraction of an em is the size of the space ONLY IF your em size is standardized. Firefox, in turn, ignores negative values for letter-spacing, so it won't add it to the word spacing.
I tested this on Firefox 13 (win/ubuntu, 14 on android), Google Chrome 20 (win/ubuntu), Android Browser on ICS 4.0.4 and IE 9. And I'm tempted to say this may also work on Safari, but I don't really know...
Here's a demo http://jsbin.com/acucam
I usually do it like this:
Make sure everything is committed, and write down the latest commit id in case something goes wrong, or create a separate branch as the backup
Run git reset --soft `git rev-list --max-parents=0 --abbrev-commit HEAD`
to reset your head to the first commit, but leave your index unchanged. All changes since the first commit will now appear ready to be committed.
Run git commit --amend -m "initial commit"
to amend your commit to the first commit and change the commit message, or if you want to keep the existing commit message, you can run git commit --amend --no-edit
Run git push -f
to force push your changes
You could also use Regular Expressions:
SELECT * FROM TABLE WHERE REGEXP_LIKE (TABLE.NAME,'IgNoReCaSe','i');
List anyObject = new ArrayList();
or
List<Object> anyObject = new ArrayList<Object>();
now anyObject
can hold objects of any type
.
use instanceof to know what kind of object it is
.
Here are the simple ways to every date format confusions:
for current date:
var current_date=new Date();

Change these values in php.ini
post_max_size = 750M
upload_max_filesize = 750M
max_execution_time = 5000
max_input_time = 5000
memory_limit = 1000M
Then restart Wamp for the changes to take effect. It will take some time. If you get following error:
Script timeout passed if you want to finish import please resubmit same zip file and import will resume.
Then update the phpMyAdmin
configuration, at phpMyAdmin\libraries\config.default.php
/**
* maximum execution time in seconds (0 for no limit)
*
* @global integer $cfg['ExecTimeLimit']
*/
$cfg['ExecTimeLimit'] = 0;
I would suggest using the strip_tags

In VS Code === Version: 1.52.1
Open VS Code settings
From the settings find the settings.json file and open it
add this code - "editor.accessibilitySupport": "off"
If you already added "editor.accessibilitySupport" with the value "on" before then simply turn it to "off". This is the code worked for me when I faced the same problem while working with one of my JS Project.
I believe the answer above is incorrect, the proper way to initialize with multiple values would be this...
int[] otherList ={1,2,3,4,5};
so the full answer with the proper initialization would look like this
int[] otherList ={1,2,3,4,5};
arList.addAll(Arrays.asList(otherList));
static final PcapLinkType[] values = { DLT_NULL, DLT_EN10MB, DLT_EN3MB, null ...}
...
public static PcapLinkType getPcapLinkTypeForInt(int num){
try{
return values[int];
}catch(ArrayIndexOutOfBoundsException e){
return DLT_UKNOWN;
}
}
I would use this code. It includes an instancesOf
function, and it runs through each number.
public class MathFunctions {
public static int mode(final int[] n) {
int maxKey = 0;
int maxCounts = 0;
for (int i : n) {
if (instancesOf(i, n) > maxCounts) {
maxCounts = instancesOf(i, n);
maxKey = i;
}
}
return maxKey;
}
public static int instancesOf(int n, int[] Array) {
int occurences = 0;
for (int j : Array) {
occurences += j == n ? 1 : 0;
}
return occurences;
}
public static void main (String[] args) {
//TODO Auto-generated method stub
System.out.println(mode(new int[] {100,200,2,300,300,300,500}));
}
}
I noticed that the code Gubatron posted doesn't work on my computer; it gave me an ArrayIndexOutOfBoundsException
.
Set the "AutoSizeColumnsMode" property to "Fill".. By default it is set to 'NONE'. Now columns will be filled across the DatagridView. Then you can set the width of other columns accordingly.
DataGridView1.Columns[0].Width=100;// The id column
DataGridView1.Columns[1].Width=200;// The abbrevation columln
//Third Colulmns 'description' will automatically be resized to fill the remaining
//space
My problem was that the nuget package manager did not do a real update but the files contained references to older versions, so i first removed all the installed mvc related packages (including razor and web api) then installed them over again and updating the version of the razor in views/web.config to version 3.0.0.
To tell from the style of your code snippet, I suppose you were using IPython rather than Jupyter Notebook.
In this issue on GitHub, it was made clear by a member of IPython in 2016 that the display of charts would only work when "only work when it's a Jupyter kernel". Thus, the %matplotlib inline
would not work.
I was just having the same issue and suggest you use Jupyter Notebook for the visualization.
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]
}
{
id:1
email:[email protected]
}
patch
so now came patch request PATCH can be sometimes idempotent
id:1
name:parth
email:[email protected]
}
patch name:w
{
id:1
name:w
email:[email protected]
}
HTTP Method GET yes POST no PUT yes PATCH no* OPTIONS yes HEAD yes DELETE yes

Although the previous answers work perfectly, I will just add another way where the elements can also be classified using the interface they have implemented.
Refer W3 Org for available interfaces
console.log(document.querySelector("#anchorelem") instanceof HTMLAnchorElement);_x000D_
console.log(document.querySelector("#divelem") instanceof HTMLDivElement);_x000D_
console.log(document.querySelector("#buttonelem") instanceof HTMLButtonElement);_x000D_
console.log(document.querySelector("#inputelem") instanceof HTMLInputElement);
_x000D_
<a id="anchorelem" href="">Anchor element</a>_x000D_
<div id="divelem">Div Element</div>_x000D_
<button id="buttonelem">Button Element</button>_x000D_
<br><input id="inputelem">
_x000D_
The interface check can be made in 2 ways as elem instanceof HTMLAnchorElement
or elem.constructor.name == "HTMLAnchorElement"
, both returns true
Try this
mainWB.Sheets.Add(After:=mainWB.Sheets(mainWB.Sheets.Count)).Name = new_sheet_name
Please add this option:
//Boolean - Whether the scale should start at zero, or an order of magnitude down from the lowest value
scaleBeginAtZero : true,
(Reference: Chart.js)
N.B: The original solution I posted was for Highcharts, if you are not using Highcharts then please remove the tag to avoid confusion
I was messing/musing on one-liners involving querySelector() & ended up here, & have a possible answer to the OP question using tag names & querySelector(), with credits to @JaredMcAteer for answering MY question, aka have RegEx-like matches with querySelector() in vanilla Javascript
Hoping the following will be useful & fit the OP's needs or everyone else's:
// basically, of before:
var youtubeDiv = document.querySelector('iframe[src="http://www.youtube.com/embed/Jk5lTqQzoKA"]')
// after
var youtubeDiv = document.querySelector('iframe[src^="http://www.youtube.com"]');
// or even, for my needs
var youtubeDiv = document.querySelector('iframe[src*="youtube"]');
Then, we can, for example, get the src stuff, etc ...
console.log(youtubeDiv.src);
//> "http://www.youtube.com/embed/Jk5lTqQzoKA"
console.debug(youtubeDiv);
//> (...)

Use os.walk to iterate recursively over directory content:
import os
root_dir = '.'
for directory, subdirectories, files in os.walk(root_dir):
for file in files:
print os.path.join(directory, file)
No real difference between os.system and subprocess.call here - unless you have to deal with strangely named files (filenames including spaces, quotation marks and so on). If this is the case, subprocess.call is definitely better, because you don't need to do any shell-quoting on file names. os.system is better when you need to accept any valid shell command, e.g. received from user in the configuration file.
var example = "I am too long string";
var result;
// Slice is JS function
result = example.slice(0, 10)+'...'; //if you need dots after the string you can add
Result variable contains "I am too l..."
Use the WebRequest class
This is to get an image:
Try
Dim _WebRequest As System.Net.WebRequest = Nothing
_WebRequest = System.Net.WebRequest.Create(http://api.hostip.info/?ip=68.180.206.184)
Catch ex As Exception
Windows.Forms.MessageBox.Show(ex.Message)
Exit Sub
End Try
Try
_NormalImage = Image.FromStream(_WebRequest.GetResponse().GetResponseStream())
Catch ex As Exception
Windows.Forms.MessageBox.Show(ex.Message)
Exit Sub
End Try
all you are right! other way to getting !

Only this worked for me:
#container:hover .cube { background-color: yellow; }
Where .cube
is CssClass of the #cube
.
Tested in Firefox, Chrome and Edge.
If you wish to achieve this using standard MS-DOS commands in a batch file then you could use:
FOR /F "TOKENS=1 eol=/ DELIMS=/ " %%A IN ('DATE/T') DO SET dd=%%A
FOR /F "TOKENS=1,2 eol=/ DELIMS=/ " %%A IN ('DATE/T') DO SET mm=%%B
FOR /F "TOKENS=1,2,3 eol=/ DELIMS=/ " %%A IN ('DATE/T') DO SET yyyy=%%C
I'm sure this can be improved upon further but this gives the date into 3 variables for Day (dd), Month (mm) and Year (yyyy). You can then use these later in your batch script as required.
SET todaysdate=%yyyy%%mm%%dd%
echo %dd%
echo %mm%
echo %yyyy%
echo %todaysdate%
While I understand an answer has been accepted for this question this alternative method may be appreciated by many looking to achieve this without using the WMI console, so I hope it adds some value to this question.
This is the Scala solution if anyone needs it
def anUnsafeOkHttpClient(): OkHttpClient = {
val manager: TrustManager =
new X509TrustManager() {
override def checkClientTrusted(x509Certificates: Array[X509Certificate], s: String) = {}
override def checkServerTrusted(x509Certificates: Array[X509Certificate], s: String) = {}
override def getAcceptedIssuers = Seq.empty[X509Certificate].toArray
}
val trustAllCertificates = Seq(manager).toArray
val sslContext = SSLContext.getInstance("SSL")
sslContext.init(null, trustAllCertificates, new java.security.SecureRandom())
val sslSocketFactory = sslContext.getSocketFactory()
val okBuilder = new OkHttpClient.Builder()
okBuilder.sslSocketFactory(sslSocketFactory, trustAllCertificates(0).asInstanceOf[X509TrustManager])
okBuilder.hostnameVerifier(new NoopHostnameVerifier)
okBuilder.build()
}
To make all 3: Model, Controller & Migration Schema of table
write in your console: php artisan make:model NameOfYourModel -mcr
One way you can achieve this is setting display: inline-block;
on the div
. It is by default a block
element, which will always fill the width it can fill (unless specifying width
of course).
inline-block
's only downside is that IE only supports it correctly from version 8. IE 6-7 only allows setting it on naturally inline
elements, but there are hacks to solve this problem.
There are other options you have, you can either float
it, or set position: absolute
on it, but these also have other effects on layout, you need to decide which one fits your situation better.
You could always try doing a ulimit -n 2048
. This will only reset the limit for your current shell and the number you specify must not exceed the hard limit
Each operating system has a different hard limit setup in a configuration file. For instance, the hard open file limit on Solaris can be set on boot from /etc/system.
set rlim_fd_max = 166384
set rlim_fd_cur = 8192
On OS X, this same data must be set in /etc/sysctl.conf.
kern.maxfilesperproc=166384
kern.maxfiles=8192
Under Linux, these settings are often in /etc/security/limits.conf.
There are two kinds of limits:
Soft limits could be set by any user while hard limits are changeable only by root. Limits are a property of a process. They are inherited when a child process is created so system-wide limits should be set during the system initialization in init scripts and user limits should be set during user login for example by using pam_limits.
There are often defaults set when the machine boots. So, even though you may reset your ulimit in an individual shell, you may find that it resets back to the previous value on reboot. You may want to grep your boot scripts for the existence ulimit commands if you want to change the default.
To reset the timer, you would need to set and clear out the timer variable
$time_out_handle = 0;
window.clearTimeout($time_out_handle);
$time_out_handle = window.setTimeout( function(){---}, 60000 );
Another simple way is to create a function and check if the checkbox(es) are checked or not, and disable a button that way using jQuery.
HTML:
<input type="checkbox" id="myCheckbox" />
<input type="submit" id="myButton" />
JavaScript:
var alterDisabledState = function () {
var isMyCheckboxChecked = $('#myCheckbox').is(':checked');
if (isMyCheckboxChecked) {
$('myButton').removeAttr("disabled");
}
else {
$('myButton').attr("disabled", "disabled");
}
}
Now you have a button that is disabled until they select the checkbox, and now you have a better user experience. I would make sure that you still do the server side validation though.

This is adapted from @maia's version, updated for modern Javascript with the deprecated initMouseEvent replaced by new MouseEvent()
and the code generally improved:
const saveTemplateAsFile = (filename, jsonToWrite) => {
const blob = new Blob([jsonToWrite], { type: "text/json" });
const link = document.createElement("a");
link.download = filename;
link.href = window.URL.createObjectURL(blob);
link.dataset.downloadurl = ["text/json", link.download, link.href].join(":");
const evt = new MouseEvent("click", {
view: window,
bubbles: true,
cancelable: true,
});
link.dispatchEvent(evt);
};
If you want to pass an object in:
const myObj = {};
const myObjAsJson = JSON.stringify(myObj);
saveTemplateAsFile(myObjAsJson);

antMatcher()
is a method of HttpSecurity
, it doesn't have anything to do with authorizeRequests()
. Basically, http.antMatcher()
tells Spring to only configure HttpSecurity
if the path matches this pattern.
The authorizeRequests().antMatchers()
is then used to apply authorization to one or more paths you specify in antMatchers()
. Such as permitAll()
or hasRole('USER3')
. These only get applied if the first http.antMatcher()
is matched.
In my case, i was facing similar issue while running multiple instance of 'npm install' on VM used for build(Windows)
Since it was a VM used only for build there was no other program locking the files. I tried disabling various antivirus settings which didn't worked. "npm cache clear" and "npm cache verify" worked but it was not a right solution for me as i cannot guess when somebody will trigger a build job from Jenkins for different release/environment leading to multiple instance of 'npm install' and hence i cannot add it to the build script nor i can go login to VM and clear/delete the cache folders manually every time.
Finally, after some research, I ended up running "npm install" with separate cache path for each job using following command:
npm install --cache path/to/some/folder
Since, all the jobs running at the same time now had a separate cache path rather than the common global path (Users/AppData/Roaming/), this issue got fixed as the jobs were no more trying to lock and access the same file, from the common npm cache.
Please note you can install a single package with a cache path as follows:
npm install packageName --cache path/to/some/folder
I was not able to find this way of giving a cache path in npm documentation but i gave it a try and it worked. I am using npm6 and looks like it works since npm5.
[Refer: How to specify cache folder in npm5 on install command?
This solution should work for other scenarios as well though may or may not be a good fit.
Also check the permissions for the directory you download the files into. For some reason when I downloaded this, by default it was saved in a folder with no access allowed! It took forever to figure out that was the problem, but I just had to change the permission for the directory and it's contents - setting it so EVERYONE = READ ONLY. Works great now.
The Google Plugin for Eclipse depends on other specific Eclipse components, such as WST. Your installation of Eclipse may not yet include all of them, but they can be easily installed by following these instructions. Eclipse 3.7 (Indigo)
Select Help > Install New Software...
Click the link for Available Software Sites.
Ensure there is an update site named Indigo.
If this is not present, click Add... and
enter http://download.eclipse.org/releases/indigo for the Location.
Now go through the installation steps; Eclipse should download and install
the plugin's dependencies.
It can also be done in some other manner
byte[] pass_byte = Encoding.ASCII.GetBytes("your input value");
and then print result. by using foreach
loop.
When I used the code mysqld_safe --skip-grant-tables &
but I get the error:
mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists.
$ systemctl stop mysql.service
$ ps -eaf|grep mysql
$ mysqld_safe --skip-grant-tables &
I solved:
$ mkdir -p /var/run/mysqld
$ chown mysql:mysql /var/run/mysqld
Now I use the same code mysqld_safe --skip-grant-tables &
and get

or If you have a mysql root account that can connect from everywhere, you should also do:
UPDATE mysql.user SET Password=PASSWORD('newpwd') WHERE User='root';
Alternate Method:
USE mysql
UPDATE user SET Password = PASSWORD('newpwd')
WHERE Host = 'localhost' AND User = 'root';
And if you have a root account that can access from everywhere:
USE mysql
UPDATE user SET Password = PASSWORD('newpwd')
WHERE Host = '%' AND User = 'root';`enter code here
now need to quit

FLUSH PRIVILEGES;
sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql start
now again ` mysql -u root -p' and use the new password to get

As I am working with Japanese characters, encoding has also been set appropriately. However, from time to time, I find that htmlentities
and htmlspecialchars
are not sufficient.
Some user inputs contain special characters that are not stripped by the above functions. In those cases I have to do this:
preg_replace('/[\x00-\x1f]/','',htmlspecialchars($string))
This will also remove certain xml-unsafe
control characters like Null character
or EOT
. You can use this table to determine which characters you wish to omit.
One possible cause is that you doesn't have permission to write on the build directory.
Solution: Delete all build directory on your project folder and rebuild your application.
So please make sure
No syntax error in directives
Browser (in App Module) and Common (in other/child) Modules are imported (Same what Günter Zöchbauer mentioned above)
If you've routes in the application then route module should be imported in App Module
All the routed component's Module are also imported in App Module, for eg: app-routing.module.ts is as follows:
const routes: Routes = [
{path: '', component: CustomerComponent},
{path: 'admin', component: AdminComponent}
];
Then App module must imports modules of CustomerComponent and AdminComponent in @NgModule().
I have answered this in another question, with all details you may need:
Detect IF hovering over element with jQuery (has 99 upvotes at the time of writing)
Basically, you can do something like:
var ishovered = oi.is(":hover");
This works only if oi
is a jQuery object containing a single element. If there are multiple elements matched, you need to apply to each element, for example:
var hoveredItem = !!$('ol>li').filter(function() { return $(this).is(":hover"); });
// not .filter(':hover'), as we can't apply :hover on multiple elements
This was tested starting jQuery 1.7.
I'd express the format as:
"1-3 dot-separated components, each numeric except that the last one may be *"
As a regexp, that's:
^(\d+\.)?(\d+\.)?(\*|\d+)$
[Edit to add: this solution is a concise way to validate, but it has been pointed out that extracting the values requires extra work. It's a matter of taste whether to deal with this by complicating the regexp, or by processing the matched groups.
In my solution, the groups capture the "."
characters. This can be dealt with using non-capturing groups as in ajborley's answer.
Also, the rightmost group will capture the last component, even if there are fewer than three components, and so for example a two-component input results in the first and last groups capturing and the middle one undefined. I think this can be dealt with by non-greedy groups where supported.
Perl code to deal with both issues after the regexp could be something like this:
@version = ();
@groups = ($1, $2, $3);
foreach (@groups) {
next if !defined;
s/\.//;
push @version, $_;
}
($major, $minor, $mod) = (@version, "*", "*");
Which isn't really any shorter than splitting on "."

Here is my global module I use -
var Cookie = {
Create: function (name, value, days) {
var expires = "";
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
expires = "; expires=" + date.toGMTString();
}
document.cookie = name + "=" + value + expires + "; path=/";
},
Read: function (name) {
var nameEQ = name + "=";
var ca = document.cookie.split(";");
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == " ") c = c.substring(1, c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
}
return null;
},
Erase: function (name) {
Cookie.create(name, "", -1);
}
};
git remote prune
and git fetch --prune
do the same thing: deleting the refs to the branches that don't exist on the remote, as you said. The second command connects to the remote and fetches its current branches before pruning.
However it doesn't touch the local branches you have checked out, that you can simply delete with
git branch -d random_branch_I_want_deleted
Replace -d
by -D
if the branch is not merged elsewhere
git prune
does something different, it purges unreachable objects, those commits that aren't reachable in any branch or tag, and thus not needed anymore.
An answer using PIL (just in case it's useful).
given a numpy array "A":

im = Image.fromarray(A)
im.save("your_file.jpeg")
you can replace "jpeg" with almost any format you want. More details about the formats here
As mentioned above by @Ricky vue-router automatically applies two active classes, .router-link-active
and .router-link-exact-active
, to the component.
So, to change active link css use:
.router-link-exact-active{
//your desired design when link is clicked
font-weight: 700;
}
This is expected.
Refer to Javadocs for split
.
Splits this string around matches of the given regular expression.
This method works as if by invoking the two-argument split(java.lang.String,int) method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.
Try this:
To unskew the image use a nested div for the image and give it the opposite skew value. So if you had 20deg on the parent then you can give the nested (image) div a skew value of -20deg.

Okay, I don't foresee any more answers on this one, so what I ended up going with for now is just a solution for rectangular images. I've used the following NinePatch:
along with the appropriate padding in XML:
<ImageView
android:id="@+id/image_test"
android:background="@drawable/drop_shadow"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="6px"
android:paddingTop="4px"
android:paddingRight="8px"
android:paddingBottom="9px"
android:src="@drawable/pic1"
/>
to get a fairly good result:
Not ideal, but it'll do.
ans=(R)
while True:
print('Your score is so far '+str(myScore)+'.')
print("Would you like to roll or quit?")
ans=input("Roll...")
if ans=='R':
R=random.randint(1, 8)
print("You rolled a "+str(R)+".")
myScore=R+myScore
else:
print("Now I'll see if I can break your score...")
ans = False
break
See this answer for a non JQuery solution. Just helped me out!
Use filter
(short version without doing a function with lambda
, using __le__
):
j2 = filter((5).__le__, j)
Example (python 3):
>>> j=[4,5,6,7,1,3,7,5]
>>> j2 = filter((5).__le__, j)
>>> j2
<filter object at 0x000000955D16DC18>
>>> list(j2)
[5, 6, 7, 7, 5]
>>>
Example (python 2):
>>> j=[4,5,6,7,1,3,7,5]
>>> j2 = filter((5).__le__, j)
>>> j2
[5, 6, 7, 7, 5]
>>>
Use __le__
i recommend this, it's very easy, __le__
is your friend
If want to sort it to desired output (both versions):
>>> j=[4,5,6,7,1,3,7,5]
>>> j2 = filter((5).__le__, j)
>>> sorted(j2)
[5, 5, 6, 7, 7]
>>>
Use sorted
>>> from timeit import timeit
>>> timeit(lambda: [i for i in j if i >= 5]) # Michael Mrozek
1.4558496298222325
>>> timeit(lambda: filter(lambda x: x >= 5, j)) # Justin Ardini
0.693048732089828
>>> timeit(lambda: filter((5).__le__, j)) # Mine
0.714461565831428

For SQL2K, something like this:
SELECT
Orders.OrderNumber
, LineItems.Quantity
, LineItems.Description
FROM (
SELECT
Orders.OrderID
, Orders.OrderNumber
, FirstLineItemID = (
SELECT TOP 1 LineItemID
FROM LineItems
WHERE LineItems.OrderID = Orders.OrderID
ORDER BY LineItemID -- or whatever else
)
FROM Orders
) Orders
JOIN LineItems
ON LineItems.OrderID = Orders.OrderID
AND LineItems.LineItemID = Orders.FirstLineItemID
Having 2 elements with the same ID is not valid html according to the W3C specification.
When your CSS selector only has an ID selector (and is not used on a specific context), jQuery uses the native document.getElementById
method, which returns only the first element with that ID.
However, in the other two instances, jQuery relies on the Sizzle selector engine (or querySelectorAll
, if available), which apparently selects both elements. Results may vary on a per browser basis.
However, you should never have two elements on the same page with the same ID. If you need it for your CSS, use a class instead.
If you absolutely must select by duplicate ID, use an attribute selector:
$('[id="a"]');
Take a look at the fiddle: http://jsfiddle.net/P2j3f/2/
Note: if possible, you should qualify that selector with a tag selector, like this:
$('span[id="a"]');
I was able to get this to work. I will describe my application and the integration test here.
The Example Application
The example application has two classes and one interface that are relevant to this problem:
These classes and the repository interface are described in the following.
The source code of the PersistenceContext
class looks as follows:
import com.jolbox.bonecp.BoneCPDataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import javax.sql.DataSource;
import java.util.Properties;
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "net.petrikainulainen.spring.datajpa.todo.repository")
@PropertySource("classpath:application.properties")
public class PersistenceContext {
protected static final String PROPERTY_NAME_DATABASE_DRIVER = "db.driver";
protected static final String PROPERTY_NAME_DATABASE_PASSWORD = "db.password";
protected static final String PROPERTY_NAME_DATABASE_URL = "db.url";
protected static final String PROPERTY_NAME_DATABASE_USERNAME = "db.username";
private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "hibernate.dialect";
private static final String PROPERTY_NAME_HIBERNATE_FORMAT_SQL = "hibernate.format_sql";
private static final String PROPERTY_NAME_HIBERNATE_HBM2DDL_AUTO = "hibernate.hbm2ddl.auto";
private static final String PROPERTY_NAME_HIBERNATE_NAMING_STRATEGY = "hibernate.ejb.naming_strategy";
private static final String PROPERTY_NAME_HIBERNATE_SHOW_SQL = "hibernate.show_sql";
private static final String PROPERTY_PACKAGES_TO_SCAN = "net.petrikainulainen.spring.datajpa.todo.model";
@Autowired
private Environment environment;
@Bean
public DataSource dataSource() {
BoneCPDataSource dataSource = new BoneCPDataSource();
dataSource.setDriverClass(environment.getRequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));
dataSource.setJdbcUrl(environment.getRequiredProperty(PROPERTY_NAME_DATABASE_URL));
dataSource.setUsername(environment.getRequiredProperty(PROPERTY_NAME_DATABASE_USERNAME));
dataSource.setPassword(environment.getRequiredProperty(PROPERTY_NAME_DATABASE_PASSWORD));
return dataSource;
}
@Bean
public JpaTransactionManager transactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());
return transactionManager;
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(dataSource());
entityManagerFactoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
entityManagerFactoryBean.setPackagesToScan(PROPERTY_PACKAGES_TO_SCAN);
Properties jpaProperties = new Properties();
jpaProperties.put(PROPERTY_NAME_HIBERNATE_DIALECT, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT));
jpaProperties.put(PROPERTY_NAME_HIBERNATE_FORMAT_SQL, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_FORMAT_SQL));
jpaProperties.put(PROPERTY_NAME_HIBERNATE_HBM2DDL_AUTO, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_HBM2DDL_AUTO));
jpaProperties.put(PROPERTY_NAME_HIBERNATE_NAMING_STRATEGY, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_NAMING_STRATEGY));
jpaProperties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));
entityManagerFactoryBean.setJpaProperties(jpaProperties);
return entityManagerFactoryBean;
}
}
Let's assume that we have a simple entity called Todo
which source code looks as follows:
@Entity
@Table(name="todos")
public class Todo {
public static final int MAX_LENGTH_DESCRIPTION = 500;
public static final int MAX_LENGTH_TITLE = 100;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Column(name = "description", nullable = true, length = MAX_LENGTH_DESCRIPTION)
private String description;
@Column(name = "title", nullable = false, length = MAX_LENGTH_TITLE)
private String title;
@Version
private long version;
}
Our repository interface has a single method called updateTitle()
which updates the title of a todo entry. The source code of the TodoRepository
interface looks as follows:
import net.petrikainulainen.spring.datajpa.todo.model.Todo;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Modifying;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import java.util.List;
public interface TodoRepository extends JpaRepository<Todo, Long> {
@Modifying
@Query("Update Todo t SET t.title=:title WHERE t.id=:id")
public void updateTitle(@Param("id") Long id, @Param("title") String title);
}
The updateTitle()
method is not annotated with the @Transactional
annotation because I think that it is best to use a service layer as a transaction boundary.
The Integration Test
The Integration Test uses DbUnit, Spring Test and Spring-Test-DBUnit. It has three components which are relevant to this problem:
These components are described with more details in the following.
The name of the DbUnit dataset file which is used to initialize the database to known state is toDoData.xml and its content looks as follows:
<dataset>
<todos id="1" description="Lorem ipsum" title="Foo" version="0"/>
<todos id="2" description="Lorem ipsum" title="Bar" version="0"/>
</dataset>
The name of the DbUnit dataset which is used to verify that the title of the todo entry is updated is called toDoData-update.xml and its content looks as follows (for some reason the version of the todo entry was not updated but the title was. Any ideas why?):
<dataset>
<todos id="1" description="Lorem ipsum" title="FooBar" version="0"/>
<todos id="2" description="Lorem ipsum" title="Bar" version="0"/>
</dataset>
The source code of the actual integration test looks as follows (Remember to annotate the test method with the @Transactional
annotation):
import com.github.springtestdbunit.DbUnitTestExecutionListener;
import com.github.springtestdbunit.TransactionDbUnitTestExecutionListener;
import com.github.springtestdbunit.annotation.DatabaseSetup;
import com.github.springtestdbunit.annotation.ExpectedDatabase;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.annotation.Rollback;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.TestExecutionListeners;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.support.DependencyInjectionTestExecutionListener;
import org.springframework.test.context.support.DirtiesContextTestExecutionListener;
import org.springframework.test.context.transaction.TransactionalTestExecutionListener;
import org.springframework.transaction.annotation.Transactional;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {PersistenceContext.class})
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
DirtiesContextTestExecutionListener.class,
TransactionalTestExecutionListener.class,
DbUnitTestExecutionListener.class })
@DatabaseSetup("todoData.xml")
public class ITTodoRepositoryTest {
@Autowired
private TodoRepository repository;
@Test
@Transactional
@ExpectedDatabase("toDoData-update.xml")
public void updateTitle_ShouldUpdateTitle() {
repository.updateTitle(1L, "FooBar");
}
}
After I run the integration test, the test passes and the title of the todo entry is updated. The only problem which I am having is that the version field is not updated. Any ideas why?
I undestand that this description is a bit vague. If you want to get more information about writing integration tests for Spring Data JPA repositories, you can read my blog post about it.
The problem is in the network layer. Here are the status codes explained:
Connection refused
: The peer is not listening on the respective network port you're trying to connect to. This usually means that either a firewall is actively denying the connection or the respective service is not started on the other site or is overloaded.
Connection timed out
: During the attempt to establish the TCP connection, no response came from the other side within a given time limit. In the context of urllib this may also mean that the HTTP response did not arrive in time. This is sometimes also caused by firewalls, sometimes by network congestion or heavy load on the remote (or even local) site.
That said, it is probably not a problem in your script, but on the remote site. If it's occuring occasionally, it indicates that the other site has load problems or the network path to the other site is unreliable.
Also, as it is a problem with the network, you cannot tell what happened on the other side. It is possible that the packets travel fine in the one direction but get dropped (or misrouted) in the other.
It is also not a (direct) DNS problem, that would cause another error (Name or service not known or something similar). It could however be the case that the DNS is configured to return different IP addresses on each request, which would connect you (DNS caching left aside) to different addresses hosts on each connection attempt. It could in turn be the case that some of these hosts are misconfigured or overloaded and thus cause the aforementioned problems.
As suggested in the another answer, using a packet analyzer can help to debug the issue. You won't see much however except the packets reflecting exactly what the error message says.
To rule out network congestion as a problem you could use a tool like mtr
or traceroute
or even ping
to see if packets get lost to the remote site. Note that, if you see loss in mtr (and any traceroute tool for that matter), you must always consider the first host where loss occurs (in the route from yours to remote) as the one dropping packets, due to the way ICMP works. If the packets get lost only at the last hop over a long time (say, 100 packets), that host definetly has an issue. If you see that this behaviour is persistent (over several days), you might want to contact the administrator.
Loss in a middle of the route usually corresponds to network congestion (possibly due to maintenance), and there's nothing you could do about it (except whining at the ISP about missing redundance).
If network congestion is not a problem (i.e. not more than, say, 5% of the packets get lost), you should contact the remote server administrator to figure out what's wrong. He may be able to see relevant infos in system logs. Running a packet analyzer on the remote site might also be more revealing than on the local site. Checking whether the port is open using netstat -tlp
is definetly recommended then.
The problem is that static imports from Hamcrest and Mockito have similar names, but return Matchers and real values, respectively.
One work-around is to simply copy the Hamcrest and/or Mockito classes and delete/rename the static functions so they are easier to remember and less show up in the auto complete. That's what I did.
Also, when using mocks, I try to avoid assertThat
in favor other other assertions
and verify
, e.g.
assertEquals(1, 1);
verify(someMock).someMethod(eq(1));
instead of
assertThat(1, equalTo(1));
verify(someMock).someMethod(eq(1));
If you remove the classes from your Favorites in Eclipse, and type out the long name e.g. org.hamcrest.Matchers.equalTo
and do CTRL+SHIFT+M to 'Add Import' then autocomplete will only show you Hamcrest matchers, not any Mockito matchers. And you can do this the other way so long as you don't mix matchers.
Apply style="text-align: right"
to the input tag. This will allow entry to be right-justified, and (at least in Firefox 3, IE 7 and Safari) will even appear to flow from the right.
A more modern approach using Promise and async/await :
toDataURL(url) {
return fetch(url).then((response) => {
return response.blob();
}).then(blob => {
return URL.createObjectURL(blob);
});
}
then
async download() {
const a = document.createElement("a");
a.href = await toDataURL("https://cdn1.iconfinder.com/data/icons/ninja-things-1/1772/ninja-simple-512.png");
a.download = "myImage.png";
document.body.appendChild(a);
a.click();
document.body.removeChild(a);
}

This error message comes specifically from the XDebug extension. PHP itself does not have a function nesting limit. Change the setting in your php.ini:
xdebug.max_nesting_level = 200
or in your PHP code:
ini_set('xdebug.max_nesting_level', 200);
As for if you really need to change it (i.e.: if there's a alternative solution to a recursive function), I can't tell without the code.
In this example, how do I specify the value of "constrArg" in
MyBeanService
with the@Autowire
annotation? Is there any way to do this?
No, not in the way that you mean. The bean representing MyConstructorClass
must be configurable without requiring any of its client beans, so MyBeanService
doesn't get a say in how MyConstructorClass
is configured.
This isn't an autowiring problem, the problem here is how does Spring instantiate MyConstructorClass
, given that MyConstructorClass
is a @Component
(and you're using component-scanning, and therefore not specifying a MyConstructorClass
explicitly in your config).
As @Sean said, one answer here is to use @Value
on the constructor parameter, so that Spring will fetch the constructor value from a system property or properties file. The alternative is for MyBeanService
to directly instantiate MyConstructorClass
, but if you do that, then MyConstructorClass
is no longer a Spring bean.
thx @suweller.
I fixed the problem:
? bin git:(master) ? brew link node
Linking /usr/local/Cellar/node/0.10.25... Warning: Could not link node. Unlinking...
Error: Permission denied - /usr/local/lib/node_modules/npm
I had the same problem as suweller:
? bin git:(master) ? ls -la /usr/local/lib/ | grep node
drwxr-xr-x 3 24561 wheel 102 11 Okt 2012 node
drwxr-xr-x 3 24561 wheel 102 27 Jan 11:32 node_modules
so i fixed this problem by:
? bin git:(master) ? sudo chown $(users) /usr/local/lib/node_modules
? bin git:(master) ? sudo chown $(users) /usr/local/lib/node
after i fixed this problem I got another one:
? bin git:(master) ? brew link node
Linking /usr/local/Cellar/node/0.10.25... Warning: Could not link node. Unlinking...
Error: Could not symlink file: /usr/local/Cellar/node/0.10.25/lib/dtrace/node.d
Target /usr/local/lib/dtrace/node.d already exists. You may need to delete it.
To force the link and overwrite all other conflicting files, do:
brew link --overwrite formula_name
To list all files that would be deleted:
brew link --overwrite --dry-run formula_name
So I removed node.d by:
? bin git:(master) ? sudo rm /usr/local/lib/dtrace/node.d
got another permission error:
? bin git:(master) ? brew link node
Linking /usr/local/Cellar/node/0.10.25... Warning: Could not link node. Unlinking...
Error: Could not symlink file: /usr/local/Cellar/node/0.10.25/lib/dtrace/node.d
/usr/local/lib/dtrace is not writable. You should change its permissions.
and fixed it:
? bin git:(master) ? sudo chown $(users) /usr/local/Cellar/node/0.10.25/lib/dtrace/node.d
and finally everything worked:
? bin git:(master) ? brew link node
Linking /usr/local/Cellar/node/0.10.25... 1225 symlinks created
As a fallback solution, you could wrap your classes in a parent element like this:
<div>
<div>This text should appear as normal</div>
<p>This text should be blue.</p>
<div>
<!-- first-child / first-of-type starts from here -->
<p class="myclass1">This text should appear red.</p>
<p class="myclass2">This text should appear green.</p>
</div>
</div>
This works better, as you can show validationMessage for a specified key:
ModelState.AddModelError("keyName","Message");
and display it like this:
@Html.ValidationMessage("keyName")
You can use:
try:
# get your models
except ObjectDoesNotExist:
# do something
For the same solution I was looking for Angularjs directive with ng-Model
.
Here is the code that resolve the problem.
myApp.directive('zipcodeformatter', function () {
return {
restrict: 'A', // only activate on element attribute
require: '?ngModel', // get a hold of NgModelController
link: function (scope, element, attrs, ngModel) {
scope.$watch(attrs.ngModel, function (v) {
if (v) {
console.log('value changed, new value is: ' + v + ' ' + v.length);
if (v.length > 5) {
var newzip = v.replace("-", '');
var str = newzip.substring(0, 5) + '-' + newzip.substring(5, newzip.length);
element.val(str);
} else {
element.val(v);
}
}
});
}
};
});

I had this exact problem with my GoDaddy account.
I am running the Linux hosting with cPanel
follow these steps and you should be fine if you are running the same hosting as me:
first, go to you Manage Your Hosting -> Manage
then you will see a section called Files, click on File Manager
you can select the Document Root for: yourwebsite.com then click GO
this should bring you right away in the public_html folder
in that folder, you can add a file (by clicking the +File in top left corner), call it phpinfo.php
right click that new file, and select edit :
right this in it and save changes:
<?php phpinfo(); ?>
it the same public_html folder, add another file called php.ini
edit this one too, right those lines:
max_execution_time 600
memory_limit 128M
post_max_size 32M
upload_max_filesize 32M
now, go back to your Manage Your Hosting -> Manage, look for PHP Process
click Kill Process, this will allows a refresh with your new settings. you are good to go
side note: you can see your new settings by navigating to yourwebiste.com/phpinfo.php
To check if a directory named "Folder" exists use:
QDir("Folder").exists();
To create a new folder named "MyFolder" use:
QDir().mkdir("MyFolder");
Just add style="width:auto"
<input type="submit" id="search" value="Search" style="width:auto" />
This worked for me in IE, Firefox and Chrome.
FileReader reads from files on the file system.
Perhaps you intended to use something like this to load a file from the class path
// this will look in src/main/resources before building and myjar.jar! after building.
InputStream is = MyClass.class.getClassloader()
.getResourceAsStream("config.txt");
Or you could extract the file from the jar before reading it.
I needed this information too and got information with this method,
Launch PowerShell
run the 'import-module servermanager' command ( without quotes )
after that for asp.net 3.5 check run the 'get-windowsfeature web-asp-net' command ( without quotes )
for asp.net 4.5 check run the 'get-windowsfeature Net-Framework-45-Core' command ( without quotes )
Both of the commands will inform you below Install State header.

From the official Spring documentation:
General interface that represents binding results. Extends the interface for error registration capabilities, allowing for a Validator to be applied, and adds binding-specific analysis and model building.
Serves as result holder for a DataBinder, obtained via the DataBinder.getBindingResult() method. BindingResult implementations can also be used directly, for example to invoke a Validator on it (e.g. as part of a unit test).
Mike's suggestion sounds like the "right way". I came across this thread wanting to specify the user to run vncserver
under on reboot and wanted to keep all my cron jobs in one place.
I was getting the following error for the VNC cron:
vncserver: The USER environment variable is not set. E.g.:
In my case, I was able to use sudo
to specify who to run the task as.
@reboot sudo -u [someone] vncserver ...
In addition to the excellent answers above, the following shows how to add text to each page of a multi-page document:
using (var reader = new PdfReader(@"C:\Input.pdf"))
{
using (var fileStream = new FileStream(@"C:\Output.pdf", FileMode.Create, FileAccess.Write))
{
var document = new Document(reader.GetPageSizeWithRotation(1));
var writer = PdfWriter.GetInstance(document, fileStream);
document.Open();
for (var i = 1; i <= reader.NumberOfPages; i++)
{
document.NewPage();
var baseFont = BaseFont.CreateFont(BaseFont.HELVETICA_BOLD, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
var importedPage = writer.GetImportedPage(reader, i);
var contentByte = writer.DirectContent;
contentByte.BeginText();
contentByte.SetFontAndSize(baseFont, 12);
var multiLineString = "Hello,\r\nWorld!".Split('\n');
foreach (var line in multiLineString)
{
contentByte.ShowTextAligned(PdfContentByte.ALIGN_LEFT, line, 200, 200, 0);
}
contentByte.EndText();
contentByte.AddTemplate(importedPage, 0, 0);
}
document.Close();
writer.Close();
}
}
You can use the MSXML Base64 encoding functionality as described at www.nonhostile.com/howto-encode-decode-base64-vb6.asp:
Function EncodeBase64(text As String) As String
Dim arrData() As Byte
arrData = StrConv(text, vbFromUnicode)
Dim objXML As MSXML2.DOMDocument
Dim objNode As MSXML2.IXMLDOMElement
Set objXML = New MSXML2.DOMDocument
Set objNode = objXML.createElement("b64")
objNode.dataType = "bin.base64"
objNode.nodeTypedValue = arrData
EncodeBase64 = objNode.Text
Set objNode = Nothing
Set objXML = Nothing
End Function
try this:
$yearnow= date("Y");
$yearnext=$yearnow+1;

You possibly do not have create permissions to the folder. So WinSCP fails to create a temporary file for the transfer.
You have two options:
Grant write permissions to the folder to the user or group you log in with (myuser
), or change the ownership of the folder to the user, or
Disable a transfer to temporary file.
In Preferences, go to Transfer > Endurance page and in Enable transfer resume/transfer to temporary file name for select Disable:

color=cm.rainbow(np.linspace(0,1,n))
for i,c in zip(range(n),color):
ax1.plot(x, y,c=c)
#or version 2: - faster and better:
color=iter(cm.rainbow(np.linspace(0,1,n)))
c=next(color)
plt.plot(x,y,c=c)
#or version 3:
color=iter(cm.rainbow(np.linspace(0,1,n)))
for i in range(n):
c=next(color)
ax1.plot(x, y,c=c)

You can create a function and then refer to it in the select statement. The function may look similar to this:
if OBJECT_ID('fn_month_name_to_number', 'IF') is not null
drop function fn_month_name_to_number
go
create function fn_month_name_to_number (@monthname varchar(25))
returns int as
begin
declare @monthno as int;
select @monthno =
case @monthname
when 'January' then 1
when 'February' then 2
when 'March' then 3
when 'April' then 4
when 'May' then 5
when 'June' then 6
when 'July' then 7
when 'August' then 8
when 'September' then 9
when 'October' then 10
when 'November' then 11
when 'December' then 12
end
return @monthno
end
Then you can query it.
select fn_month_name_to_number ('February') as month_no
This query will return 2 as month number. You can pass values from a column as parameters to the function.
select fn_month_name_to_number (*columnname*) as month_no from *tablename*
Have a good day!
The problem is your query returned false
meaning there was an error in your query. After your query you could do the following:
if (!$result) {
die(mysqli_error($link));
}
Or you could combine it with your query:
$results = mysqli_query($link, $query) or die(mysqli_error($link));
That will print out your error.
Also... you need to sanitize your input. You can't just take user input and put that into a query. Try this:
$query = "SELECT * FROM shopsy_db WHERE name LIKE '%" . mysqli_real_escape_string($link, $searchTerm) . "%'";
In reply to: Table 'sookehhh_shopsy_db.sookehhh_shopsy_db' doesn't exist
Are you sure the table name is sookehhh_shopsy_db? maybe it's really like users or something.

The best solution for this is to create a simple parent pom file project (with packaging 'pom') generically for all projects from your organization.
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>your.company</groupId>
<artifactId>company-parent</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>pom</packaging>
<distributionManagement>
<repository>
<id>nexus-site</id>
<url>http://central_nexus/server</url>
</repository>
</distributionManagement>
</project>
This can be built, released, and deployed to your local nexus so everyone has access to its artifact.
Now for all projects which you wish to use it, simply include this section:
<parent>
<groupId>your.company</groupId>
<artifactId>company-parent</artifactId>
<version>1.0.0</version>
</parent>
This solution will allow you to easily add other common things to all your company's projects. For instance if you wanted to standardize your JUnit usage to a specific version, this would be the perfect place for that.
If you have projects that use multi-module structures that have their own parent, Maven also supports chaining inheritance so it is perfectly acceptable to make your project's parent pom file refer to your company's parent pom and have the project's child modules not even aware of your company's parent.
I see from your example project structure that you are attempting to put your parent project at the same level as your aggregator pom. If your project needs its own parent, the best approach I have found is to include the parent at the same level as the rest of the modules and have your aggregator pom.xml file at the root of where all your modules' directories exist.
- pom.xml (aggregator)
- project-parent
- project-module1
- project-module2
What you do with this structure is include your parent module in the aggregator and build everything with a mvn install
from the root directory.
We use this exact solution at my organization and it has stood the test of time and worked quite well for us.
Not exactly an answer to the question because the question already has great answers. This is a side info. Enabling general_log really put a dent on MySQL performance. I left general_log =1
accidentally on a production server and spent hours finding out why performance was not comparable to a similar setup on other servers. Then I found this which explains the impact of enabling general log. http://www.fromdual.com/general_query_log_vs_mysql_performance.
Gist of the story, don't put general_log=1
in the .cnf
file. Instead use set global general_log =1
for a brief duration just to log enough to find out what you are trying to find out and then turn it off.
After a lot of digging around I finally ended up downloading the source code of the recovery section of Android. Turns out you can actually send commands to the recovery.
* The arguments which may be supplied in the recovery.command file:
* --send_intent=anystring - write the text out to recovery.intent
* --update_package=path - verify install an OTA package file
* --wipe_data - erase user data (and cache), then reboot
* --wipe_cache - wipe cache (but not user data), then reboot
* --set_encrypted_filesystem=on|off - enables / diasables encrypted fs
Those are the commands you can use according to the one I found but that might be different for modded files. So using adb you can do this:
adb shell
recovery --wipe_data
Using --wipe_data seemed to do what I was looking for which was handy although I have not fully tested this as of yet.
EDIT:
For anyone still using this topic, these commands may change based on which recovery you are using. If you are using Clockword recovery, these commands should still work. You can find other commands in /cache/recovery/command
For more information please see here: https://github.com/CyanogenMod/android_bootable_recovery/blob/cm-10.2/recovery.c
You will have to use javascript, or the JQuery framework to do that. her is an example using Jquery
$('#toggle').click(function () {
//check if checkbox is checked
if ($(this).is(':checked')) {
$('#sendNewSms').removeAttr('disabled'); //enable input
} else {
$('#sendNewSms').attr('disabled', true); //disable input
}
});

The easiest way would be to set the value of the form element. If you're using jQuery (which I would highly recommend) you can do this easily with
$('#element-id').val('')
For all input elements in the form this may work (i've never tried it)
$('#form-id').children('input').val('')
Note that .children will only find input elements one level down. If you need to find grandchildren or such .find() should work.
There may be a better way however this should work for you.

It is true that if you present a view controller modally on the iPhone, it will always be presented full screen no matter how you present it on the top view controller of a navigation controller or any other way around. But you can always show the navigation bar with the following workaround way:
Rather than presenting that view controller modally present a navigation controller modally with its root view controller set as the view controller you want:
MyViewController *myViewController = [[MyViewController alloc] initWithNibName:nil bundle:nil];
UINavigationController *navigationController =
[[UINavigationController alloc] initWithRootViewController:myViewController];
//now present this navigation controller modally
[self presentViewController:navigationController
animated:YES
completion:^{
}];
You should see a navigation bar when your view is presented modally.
Uncaught InvalidValueError: setPosition: not a LatLng or LatLngLiteral: in property lat: not a number
Means you are not passing numbers into the google.maps.LatLng constructor. Per your comment:
/*Information from chromium debugger
trader: Object
geo: Object
lat: "49.014821"
lon: "10.985072"
*/
trader.geo.lat and trader.geo.lon are strings, not numbers. Use parseFloat to convert them to numbers:
var myLatlng = new google.maps.LatLng(parseFloat(trader.geo.lat),parseFloat(trader.geo.lon));
As per your question vertical listing have a scrollbar effect.

You will have to open the file in one way or another if you want to access the data within it. Obviously, one way is to open it in your Excel application instance, e.g.:-
(untested code)
Dim wbk As Workbook
Set wbk = Workbooks.Open("C:\myworkbook.xls")
' now you can manipulate the data in the workbook anyway you want, e.g. '
Dim x As Variant
x = wbk.Worksheets("Sheet1").Range("A6").Value
Call wbk.Worksheets("Sheet2").Range("A1:G100").Copy
Call ThisWorbook.Worksheets("Target").Range("A1").PasteSpecial(xlPasteValues)
Application.CutCopyMode = False
' etc '
Call wbk.Close(False)
Another way to do it would be to use the Excel ADODB provider to open a connection to the file and then use SQL to select data from the sheet you want, but since you are anyway working from within Excel I don't believe there is any reason to do this rather than just open the workbook. Note that there are optional parameters for the Workbooks.Open() method to open the workbook as read-only, etc.
First, factor consists of indices and levels. This fact is very very important when you are struggling with factor.
For example,
> z <- factor(letters[c(3, 2, 3, 4)])
# human-friendly display, but internal structure is invisible
> z
[1] c b c d
Levels: b c d
# internal structure of factor
> unclass(z)
[1] 2 1 2 3
attr(,"levels")
[1] "b" "c" "d"
here, z
has 4 elements.
The index is 2, 1, 2, 3
in that order.
The level is associated with each index: 1 -> b, 2 -> c, 3 -> d.
Then, as.numeric
converts simply the index part of factor into numeric.
as.character
handles the index and levels, and generates character vector expressed by its level.
?as.numeric
says that Factors are handled by the default method.
You simply select dates that are higher than the current time minus 1 day.
SELECT * FROM news WHERE date >= now() - INTERVAL 1 DAY;
You could use Kernel#test
:
test ?d, 'some directory'
it gets it's origins from https://ss64.com/bash/test.html
you will notice bash test
has this flag -d
to test if a directory exists
-d file True if file is a Directory. [[ -d demofile ]]
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.
Enclosed in {} represents an object; enclosed in [] represents an array, there can be multiple objects in the array
example object :
{
"brand": "bwm",
"price": 30000
}
{
"brand": "benz",
"price": 50000
}
example array:
[
{
"brand": "bwm",
"price": 30000
},
{
"brand": "benz",
"price": 50000
}

You could use On Error Resume Next
then there is no need to loop through all the sheets in the workbook.
With On Error Resume Next
the errors are not propagated, but are suppressed instead. So here when the sheets does't exist or when for any reason can't be deleted, nothing happens. It is like when you would say : delete this sheets, and if it fails I don't care. Excel is supposed to find the sheet, you will not do any searching.
Note: When the workbook would contain only those two sheets, then only the first sheet will be deleted.
Dim book
Dim sht as Worksheet
set book= Workbooks("SomeBook.xlsx")
On Error Resume Next
Application.DisplayAlerts=False
Set sht = book.Worksheets("ID Sheet")
sht.Delete
Set sht = book.Worksheets("Summary")
sht.Delete
Application.DisplayAlerts=True
On Error GoTo 0

You can use this code to check whether the input string contains any spaces?
public static void main(String[]args)
{
Scanner sc=new Scanner(System.in);
System.out.println("enter the string...");
String s1=sc.nextLine();
int l=s1.length();
int count=0;
for(int i=0;i<l;i++)
{
char c=s1.charAt(i);
if(c==' ')
{
System.out.println("spaces are in the position of "+i);
System.out.println(count++);
}
else
{
System.out.println("no spaces are there");
}
}
I imagine that you define your image something like this:
<img id="image_portrait" src="" alt="chef etat" width="120" height="135" />
You can simply load/update image for this tag and chage/set atts (width,height):
var imagelink;
var height;
var width;
$("#image_portrait").attr("src", imagelink);
$("#image_portrait").attr("width", width);
$("#image_portrait").attr("height", height);

result = System.currentTimeMillis() - now;

If df
is a pandas.DataFrame
then df['new_col']= Series list_object of length len(df)
will add the or Series list_object as a column named 'new_col'
. df['new_col']= scalar
(such as 5 or 6 in your case) also works and is equivalent to df['new_col']= [scalar]*len(df)
So a two-line code serves the purpose:
df = pd.DataFrame({'a':[1, 2], 'b':[3, 4]})
s = pd.Series({'s1':5, 's2':6})
for x in s.index:
df[x] = s[x]
Output:
a b s1 s2
0 1 3 5 6
1 2 4 5 6
This happens every time you insert/ update and you don't use single quotes. When the variable is empty it will result in that error. Fix it by using ''
Assuming the first parameter is an empty variable here is a simple example:
Wrong
nvl( ,0)
Fix
nvl('' ,0)
Put your query into your database software and check it for that error. Generally this is an easy fix
Lets say an ArrayList object(myList) is filled with those numbers and in that, 2 numbers x and y are missing.So the possible solution can be:
int k = 1;
while (k < 100) {
if (!myList.contains(k)) {
System.out.println("Missing No:" + k);
}
k++;
}
In case you are running it on Fedora or CentOS, this is what worked for me (PostgreSQL 9.6):
In terminal:
$ sudo visudo -f /etc/sudoers
modify the following text from:
Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin
to
Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/pgsql-9.6/bin
exit, then:
$ printenv PATH
$ sudo su postgres
$ psql
To exit postgreSQL terminal, you need to digit:
$ \q

IF you want more data in you confusion matrix, including "totals column" and "totals line", and percents (%) in each cell, like matlab default (see image below)
including the Heatmap and other options...
You should have fun with the module above, shared in the github ; )
https://github.com/wcipriano/pretty-print-confusion-matrix
This module can do your task easily and produces the output above with a lot of params to customize your CM:
This may help others where there is no option to Enable/Disable the history anywhere in Task Scheduler.
Open Event Viewer (either in Computer Management or Admin Tools > Event Viewer).
In Event Viewer make sure the Preview Pane is showing (View > Preview Pane should be ticked)
In the left hand pane expand Application and Service Logs then Microsoft, Windows, TaskScheduler and then select Operational.
You should have Actions showing in the preview pane with two sections - Operational and below that Event nnn, TaskScheduler. One of the items listed in the Operational section should be Properties. Click this item and the Enable Logging option is on the General tab.
My problem was that the maximum log size had been reached and even though the overwrite old events option was selected it wasn't logging new events. I suspect that might have been a permissions issue but I changed it to Archive when full and all is now working again.
Hope this helps someone else out there. If you don't have the options I've mentioned above I'm sorry, but I don't know where you should look.
This solution works well, I tested on my phone:
document.body.ontouchend = function() { document.querySelector('[name="name"]').focus(); };
enjoy
Try defaulting the exports in your components:
import React from 'react';
import Navbar from 'react-bootstrap/lib/Navbar';
export default class MyNavbar extends React.Component {
render(){
return (
<Navbar className="navbar-dark" fluid>
...
</Navbar>
);
}
}
by using default you express that's going to be member in that module which would be imported if no specific member name is provided. You could also express you want to import the specific member called MyNavbar by doing so: import {MyNavbar} from './comp/my-navbar.jsx'; in this case, no default is needed

Update: Google Forms can now upload files. This answer was posted before Google Forms had the capability to upload files.
This solution does not use Google Forms. This is an example of using an Apps Script Web App, which is very different than a Google Form. A Web App is basically a website, but you can't get a domain name for it. This is not a modification of a Google Form, which can't be done to upload a file.
NOTE: I did have an example of both the UI Service and HTML Service, but have removed the UI Service example, because the UI Service is deprecated.
NOTE: The only sandbox setting available is now IFRAME
. I you want to use an onsubmit
attribute in the beginning form tag: <form onsubmit="myFunctionName()">
, it may cause the form to disappear from the screen after the form submission.
If you were using NATIVE mode, your file upload Web App may no longer be working. With NATIVE mode, a form submission would not invoke the default behavior of the page disappearing from the screen. If you were using NATIVE mode, and your file upload form is no longer working, then you may be using a "submit" type button. I'm guessing that you may also be using the "google.script.run" client side API to send data to the server. If you want the page to disappear from the screen after a form submission, you could do that another way. But you may not care, or even prefer to have the page stay on the screen. Depending upon what you want, you'll need to configure the settings and code a certain way.
If you are using a "submit" type button, and want to continue to use it, you can try adding event.preventDefault();
to your code in the submit event handler function. Or you'll need to use the google.script.run
client side API.
A custom form for uploading files from a users computer drive, to your Google Drive can be created with the Apps Script HTML Service. This example requires writing a program, but I've provide all the basic code here.
This example shows an upload form with Google Apps Script HTML Service.
There are various ways to end up at the Google Apps Script code editor.
I mention this because if you are not aware of all the possibilities, it could be a little confusing. Google Apps Script can be embedded in a Google Site, Sheets, Docs or Forms, or used as a stand alone app.
This example is a "Stand Alone" app with HTML Service.
HTML Service - Create a web app using HTML, CSS and Javascript
Google Apps Script only has two types of files inside of a Project
:
Script files have a .gs
extension. The .gs
code is a server side code written in JavaScript, and a combination of Google's own API.
Copy and Paste the following code
Save It
Create the first Named Version
Publish it
Set the Permissions
and you can start using it.
Code.gs file (Created by Default)
//For this to work, you need a folder in your Google drive named:
// 'For Web Hosting'
// or change the hard coded folder name to the name of the folder
// you want the file written to
function doGet(e) {
return HtmlService.createTemplateFromFile('Form')
.evaluate() // evaluate MUST come before setting the Sandbox mode
.setTitle('Name To Appear in Browser Tab')
.setSandboxMode();//Defaults to IFRAME which is now the only mode available
}
function processForm(theForm) {
var fileBlob = theForm.picToLoad;
Logger.log("fileBlob Name: " + fileBlob.getName())
Logger.log("fileBlob type: " + fileBlob.getContentType())
Logger.log('fileBlob: ' + fileBlob);
var fldrSssn = DriveApp.getFolderById(Your Folder ID);
fldrSssn.createFile(fileBlob);
return true;
}
Create an html file:
<!DOCTYPE html>
<html>
<head>
<base target="_top">
</head>
<body>
<h1 id="main-heading">Main Heading</h1>
<br/>
<div id="formDiv">
<form id="myForm">
<input name="picToLoad" type="file" /><br/>
<input type="button" value="Submit" onclick="picUploadJs(this.parentNode)" />
</form>
</div>
<div id="status" style="display: none">
<!-- div will be filled with innerHTML after form submission. -->
Uploading. Please wait...
</div>
</body>
<script>
function picUploadJs(frmData) {
document.getElementById('status').style.display = 'inline';
google.script.run
.withSuccessHandler(updateOutput)
.processForm(frmData)
};
// Javascript function called by "submit" button handler,
// to show results.
function updateOutput() {
var outputDiv = document.getElementById('status');
outputDiv.innerHTML = "The File was UPLOADED!";
}
</script>
</html>
This is a full working example. It only has two buttons and one <div>
element, so you won't see much on the screen. If the .gs
script is successful, true is returned, and an onSuccess
function runs. The onSuccess function (updateOutput) injects inner HTML into the div
element with the message, "The File was UPLOADED!"
File
, Manage Version
then Save the first VersionPublish
, Deploy As Web App
then UpdateWhen you run the Script the first time, it will ask for permissions because it's saving files to your drive. After you grant permissions that first time, the Apps Script stops, and won't complete running. So, you need to run it again. The script won't ask for permissions again after the first time.
The Apps Script file will show up in your Google Drive. In Google Drive you can set permissions for who can access and use the script. The script is run by simply providing the link to the user. Use the link just as you would load a web page.
Another example of using the HTML Service can be seen at this link here on StackOverflow:
NOTES about deprecated UI Service:
There is a difference between the UI Service, and the Ui getUi()
method of the Spreadsheet Class (Or other class) The Apps Script UI Service was deprecated on Dec. 11, 2014. It will continue to work for some period of time, but you are encouraged to use the HTML Service.
Google Documentation - UI Service
Even though the UI Service is deprecated, there is a getUi()
method of the spreadsheet class to add custom menus, which is NOT deprecated:
Spreadsheet Class - Get UI method
I mention this because it could be confusing because they both use the terminology UI.
The UI method returns a Ui
return type.
You can add HTML to a UI Service, but you can't use a <button>
, <input>
or <script>
tag in the HTML with the UI Service.
Here is a link to a shared Apps Script Web App file with an input form:
As explained before:
ALTER TABLE TABLEName
drop CONSTRAINT FK_CONSTRAINTNAME;
ALTER TABLE TABLENAME
ADD CONSTRAINT FK_CONSTRAINTNAME
FOREIGN KEY (FId)
REFERENCES OTHERTABLE
(Id)
ON DELETE CASCADE ON UPDATE NO ACTION;
As you can see those have to be separated commands, first dropping then adding.
Function overloading occurs when you define the same function name twice (or more) using different set of parameters. For example:
class Addition {
function compute($first, $second) {
return $first+$second;
}
function compute($first, $second, $third) {
return $first+$second+$third;
}
}
In the example above, the function compute
is overloaded with two different parameter signatures. *This is not yet supported in PHP. An alternative is to use optional arguments:
class Addition {
function compute($first, $second, $third = 0) {
return $first+$second+$third;
}
}
Function overriding occurs when you extend a class and rewrite a function which existed in the parent class:
class Substraction extends Addition {
function compute($first, $second, $third = 0) {
return $first-$second-$third;
}
}
For example, compute
overrides the behavior set forth in Addition
.
Static methods cannot be inherited or overridden, and that is why they can't be abstract. Since static methods are defined on the type, not the instance, of a class, they must be called explicitly on that type. So when you want to call a method on a child class, you need to use its name to call it. This makes inheritance irrelevant.
Assume you could, for a moment, inherit static methods. Imagine this scenario:
public static class Base
{
public static virtual int GetNumber() { return 5; }
}
public static class Child1 : Base
{
public static override int GetNumber() { return 1; }
}
public static class Child2 : Base
{
public static override int GetNumber() { return 2; }
}
If you call Base.GetNumber(), which method would be called? Which value returned? It's pretty easy to see that without creating instances of objects, inheritance is rather hard. Abstract methods without inheritance are just methods that don't have a body, so can't be called.
I was having this issue as well and the problem was in the view controllers. I'm not sure how your application is structured, so I'll just explain what I found. I'm pretty new to xcode and coding, so bear with me.
I was trying to programmatically change the text on a UILabel. Using "self.mylabel.text" worked fine until I added another view controller under the same class that didn't also include that label. That is when I got the error that you're seeing. When I added the same UILabel and connected it into that additional view controller, the error went away.
In short, it seems that in Swift, all view controllers assigned to the same class have to reference the code you have in there, or else you get an error. If you have two different view controllers with different code, assign them to different classes. This worked for me and hopefully applies to what you're doing.
Do this using rs.next()
:
while (rs.next())
{
...
}
If the result set is empty, the code inside the loop won't execute.
I tried many ways but this works.
Sample code is availalbe in DBCC SHRINKFILE
USE DBName;
GO
-- Truncate the log by changing the database recovery model to SIMPLE.
ALTER DATABASE DBName
SET RECOVERY SIMPLE;
GO
-- Shrink the truncated log file to 1 MB.
DBCC SHRINKFILE (DBName_log, 1); --File name SELECT * FROM sys.database_files; query to get the file name
GO
-- Reset the database recovery model.
ALTER DATABASE DBName
SET RECOVERY FULL;

A function I have in an install script made for exactly this
function assertInstalled() {
for var in "$@"; do
if ! which $var &> /dev/null; then
echo "Install $var!"
exit 1
fi
done
}
example call:
assertInstalled zsh vim wget python pip git cmake fc-cache
Lots of answers. May be this one will also help-
Intent intent = new Intent(activity, SignInActivity.class)
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK)
.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
this.startActivity(intent);
this.finish();
Kotlin version-
Intent(this, SignInActivity::class.java).apply {
addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK)
addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
}.also { startActivity(it) }
finish()
No you don't have to put credentials, You have to put headers on client side eg:
$http({
url: 'url of service',
method: "POST",
data: {test : name },
withCredentials: true,
headers: {
'Content-Type': 'application/json; charset=utf-8'
}
});
And and on server side you have to put headers to this is example for nodejs:
/**
* On all requests add headers
*/
app.all('*', function(req, res,next) {
/**
* Response settings
* @type {Object}
*/
var responseSettings = {
"AccessControlAllowOrigin": req.headers.origin,
"AccessControlAllowHeaders": "Content-Type,X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5, Date, X-Api-Version, X-File-Name",
"AccessControlAllowMethods": "POST, GET, PUT, DELETE, OPTIONS",
"AccessControlAllowCredentials": true
};
/**
* Headers
*/
res.header("Access-Control-Allow-Credentials", responseSettings.AccessControlAllowCredentials);
res.header("Access-Control-Allow-Origin", responseSettings.AccessControlAllowOrigin);
res.header("Access-Control-Allow-Headers", (req.headers['access-control-request-headers']) ? req.headers['access-control-request-headers'] : "x-requested-with");
res.header("Access-Control-Allow-Methods", (req.headers['access-control-request-method']) ? req.headers['access-control-request-method'] : responseSettings.AccessControlAllowMethods);
if ('OPTIONS' == req.method) {
res.send(200);
}
else {
next();
}
});
If you prefer a one-liner:
matched_lines = [line for line in my_string.split('\n') if "substring" in line]
You can also define a STYLE for your editText so you can regroup all properties in common. It is very powerful if you have to multiple edit text that need to has the behaviour
Put the code in res/values/styles.xml
<style name="MyEditTextStyle" parent="@android:style/TextAppearance.Widget.EditText"> <item name="android:background">@color/transparence</item> //NO UNDERBAR <item name="android:maxLines">1</item> <item name="android:height">28dp</item> //COMMON HEIGHT </style>
After that you just need to call it in your editText
<EditText
android:id="@+id/edit1"
style="@style/MyEditTextStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<EditText
android:id="@+id/edit2"
style="@style/MyEditTextStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
Run away from store procedures as much as possible. They are pretty hard to maintain and are VERY OLD STUFF ;)
Eureka ! Finally I found a solution on this.
This is caused by Windows update that stops any 32-bit processes from consuming more than 1200 MB on a 64-bit machine. The only way you can repair this is by using the System Restore option on Win 7.
Start >> All Programs >> Accessories >> System Tools >> System Restore.
And then restore to a date on which your Java worked fine. This worked for me. What is surprising here is Windows still pushes system updates under the name of "Critical Updates" even when you disable all windows updates. ^&%)#* Windows :-)
Downloading a file requires you to read it, either way you will have to go through the file in some way. Instead of line by line, you can just read it by bytes from the stream:
BufferedInputStream in = new BufferedInputStream(new URL("http://www.website.com/information.asp").openStream())
byte data[] = new byte[1024];
int count;
while((count = in.read(data,0,1024)) != -1)
{
out.write(data, 0, count);
}
There are a few ways to do it. If I want to read and write binary I usually use open()
, read()
, write()
, close()
. Which are completely different than doing a byte at a time. You work with integer file descriptors instead of FILE * variables. fileno will get an integer descriptor from a FILE * BTW. You read a buffer full of data, say 32k bytes at once. The buffer is really an array which you can read from really fast because it's in memory. And reading and writing many bytes at once is faster than one at a time. It's called a blockread in Pascal I think, but read() is the C equivalent.
I looked but I don't have any examples handy. OK, these aren't ideal because they also are doing stuff with JPEG images. Here's a read, you probably only care about the part from open() to close(). fbuf is the array to read into, sb.st_size is the file size in bytes from a stat() call.
fd = open(MASKFNAME,O_RDONLY);
if (fd != -1) {
read(fd,fbuf,sb.st_size);
close(fd);
splitmask(fbuf,(uint32_t)sb.st_size); // look at lines, etc
have_mask = 1;
}
Here's a write: (here pix is the byte array, jwidth and jheight are the JPEG width and height so for RGB color we write height * width * 3 color bytes). It's the # of bytes to write.
void simpdump(uint8_t *pix, char *nm) { // makes a raw aka .data file
int sdfd;
sdfd = open(nm,O_WRONLY | O_CREAT);
if (sdfd == -1) {
printf("bad open\n");
exit(-1);
}
printf("width: %i height: %i\n",jwidth,jheight); // to the console
write(sdfd,pix,(jwidth*jheight*3));
close(sdfd);
}
Look at man 2 open, also read, write, close. Also this old-style jpeg example.c: https://github.com/LuaDist/libjpeg/blob/master/example.c I'm reading and writing an entire image at once here. But they're binary reads and writes of bytes, just a lot at once.
"But when I try to read from a file it is not outputting correctly." Hmmm. If you read a number 65 that's (decimal) ASCII for an A. Maybe you should look at man ascii too. If you want a 1 that's ASCII 0x31. A char variable is a tiny 8-bit integer really, if you do a printf as a %i you get the ASCII value, if you do a %c you get the character. Do %x for hexadecimal. All from the same number between 0 and 255.
Passing null as the IFormatProvider
is not the correct way to do this. If the user has a custom date/time format on their PC you'll have issues in parsing and converting to string. I've just fixed a bug where somebody had passed null as the IFormatProvider when converting to string.
Instead you should be using CultureInfo.InvariantCulture
Wrong:
string output = theDate.ToString("dd/MM/yy HH:mm:ss.fff", null);
Correct:
string output = theDate.ToString("dd/MM/yy HH:mm:ss.fff", CultureInfo.InvariantCulture);
simplify2array
is a base function that is fairly intuitive. However, since R's default is to fill in data by columns first, you will need to transpose the output. (sapply
uses simplify2array
, as documented in help(sapply)
.)

On Android the same rules apply as in a normal Java environment. In Java threads are not killed, but the stopping of a thread is done in a cooperative way. The thread is asked to terminate and the thread can then shutdown gracefully.
Often a volatile boolean
field is used which the thread periodically checks and terminates when it is set to the corresponding value.
I would not use a boolean
to check whether the thread should terminate. If you use volatile
as a field modifier, this will work reliable, but if your code becomes more complex, for instead uses other blocking methods inside the while
loop, it might happen, that your code will not terminate at all or at least takes longer as you might want.
Certain blocking library methods support interruption.
Every thread has already a boolean flag interrupted status and you should make use of it. It can be implemented like this:
public void run() {
try {
while(!Thread.currentThread().isInterrupted()) {
// ...
}
} catch (InterruptedException consumed)
/* Allow thread to exit */
}
}
public void cancel() { interrupt(); }
Source code taken from Java Concurrency in Practice. Since the cancel()
method is public you can let another thread invoke this method as you wanted.
There is also a poorly named static method interrupted
which clears the interrupted status of the current thread.
If you have Iterable convert to stream and find last element
Iterator<String> sourceIterator = Arrays.asList("one", "two", "three").iterator();
Iterable<String> iterable = () -> sourceIterator;
String last = StreamSupport.stream(iterable.spliterator(), false).reduce((first, second) -> second).orElse(null);
Objects in JavaScript are collections of unordered properties. Objects are hashtables.
If you want your properties to be in alphabetical order, one possible solution would be to create an index for your properties in a separate array. Just a few hours ago, I answered a question on Stack Overflow which you may want to check out:
Here's a quick adaptation for your object1:
var obj = {
"set1": [1, 2, 3],
"set2": [4, 5, 6, 7, 8],
"set3": [9, 10, 11, 12]
};
var index = [];
// build the index
for (var x in obj) {
index.push(x);
}
// sort the index
index.sort(function (a, b) {
return a == b ? 0 : (a > b ? 1 : -1);
});
Then you would be able to do the following:
console.log(obj[index[1]]);
The answer I cited earlier proposes a reusable solution to iterate over such an object. That is unless you can change your JSON to as @Jacob Relkin suggested in the other answer, which could be easier.
1 You may want to use the hasOwnProperty()
method to ensure that the properties belong to your object and are not inherited from Object.prototype
.
<html>
<head>
<script>
function callme(field) {
alert("field:" + field.value);
}
</script>
</head>
<body>
<form name="f1">
<input type="text" onkeyup="callme(this);" name="text1">
</form>
</body>
</html>
It looks like you can use the onkeyup to get the new value of the HTML input control. Hope it helps.
CoolGoose's solution is good but this is faster for large files (as it only tries to read 1 byte):
if (false === file_get_contents("http://example.com/path/to/image",0,null,0,1)) {
$image = $default_image;
}
When you are using foreach loop within view for binded model ... Your model is supposed to be in listed format.
i.e
@model IEnumerable<ViewModels.MyViewModels>
@{
if (Model.Count() > 0)
{
@Html.DisplayFor(modelItem => Model.Theme.FirstOrDefault().name)
@foreach (var theme in Model.Theme)
{
@Html.DisplayFor(modelItem => theme.name)
@foreach(var product in theme.Products)
{
@Html.DisplayFor(modelItem => product.name)
@foreach(var order in product.Orders)
{
@Html.TextBoxFor(modelItem => order.Quantity)
@Html.TextAreaFor(modelItem => order.Note)
@Html.EditorFor(modelItem => order.DateRequestedDeliveryFor)
}
}
}
}else{
<span>No Theam avaiable</span>
}
}
Exception#backtrace has the entire stack in it:
def do_division_by_zero; 5 / 0; end
begin
do_division_by_zero
rescue => exception
puts exception.backtrace
raise # always reraise
end
