You can use isin
method:
In [1]: df = pd.DataFrame({'A': [5,6,3,4], 'B': [1,2,3,5]})
In [2]: df
Out[2]:
A B
0 5 1
1 6 2
2 3 3
3 4 5
In [3]: df[df['A'].isin([3, 6])]
Out[3]:
A B
1 6 2
2 3 3
And to get the opposite use ~
:
In [4]: df[~df['A'].isin([3, 6])]
Out[4]:
A B
0 5 1
3 4 5
Here is a version that I got to work on my system.
import matplotlib.pyplot as plt
from drawnow import drawnow
import numpy as np
def makeFig():
plt.scatter(xList,yList) # I think you meant this
plt.ion() # enable interactivity
fig=plt.figure() # make a figure
xList=list()
yList=list()
for i in np.arange(50):
y=np.random.random()
xList.append(i)
yList.append(y)
drawnow(makeFig)
#makeFig() The drawnow(makeFig) command can be replaced
#plt.draw() with makeFig(); plt.draw()
plt.pause(0.001)
The drawnow(makeFig) line can be replaced with a makeFig(); plt.draw() sequence and it still works OK.
Try this:

/* I want to get an IPv4 IP address */
ifr.ifr_addr.sa_family = AF_INET;
/* I want IP address attached to "eth0" */
strncpy(ifr.ifr_name, "eth0", IFNAMSIZ-1);
ioctl(fd, SIOCGIFADDR, &ifr);
close(fd);
/* display result */
printf("%s\n", inet_ntoa(((struct sockaddr_in *)&ifr.ifr_addr)->sin_addr));

The code sample is taken from here.
There are some very good answers here. I'd like to add the following here as well:
some_dict = {
"foo": "bar",
"lorem": "ipsum"
}
for index, (key, value) in enumerate(some_dict.items()):
print(index, key, value)
results in
0 foo bar

Could the Barcode Rendering Framework at Codeplex GitHub be of help?
Use data type 'MultilineText':
[DataType(DataType.MultilineText)]
public string Text { get; set; }
You can use UNION ALL instead.
SELECT mt.ID, mt.ParentID, ot.MasterID
FROM dbo.MainTable AS mt
Union ALL
SELECT mt.ID, mt.ParentID, ot.MasterID
FROM dbo.OtherTable AS ot
The below code works for me -:
jQuery('[id^=select_] > option').each(function(){
if (this.text.toLowerCase()=='text'){
jQuery('[id^=select_]').val(this.value);
}
});
jQuery('[id^=select_]') - This allows you to select drop down where ID of the drop down starts from select_
Hope the above helps!

If you already have material-icons working in your web project, just need to update your reference in the html file and the used class for icons:
html reference:
Before
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet" />
After
<link href="https://fonts.googleapis.com/css?family=Material+Icons|Material+Icons+Outlined|Material+Icons+Two+Tone|Material+Icons+Round|Material+Icons+Sharp"
rel="stylesheet" />
material icons class:
After that just check wich className are you using:
Before:
<i className="material-icons">weekend</i>
After:
<i className="material-icons-outlined">weekend</i>
that works for me... Pura vida!
I use package hyphenat
and then write compound words like Finnish word Internet-yhteys (Eng. Internet connection) as Internet\hyp yhteys
. Looks goofy but seems to be the most elegant way I've found.
You should add "throws IOException" to your main method:
public static void main(String[] args) throws IOException {
You can read a bit more about checked exceptions (which are specific to Java) in JLS.
In Android Studio you can add Hint (Place holder) through GUI. First select EditText field on designer view. Then Click on Component Tree Left side of IDE (Normally it's there, but it may be there minimized) There you can see Properties of selected EditText. Find Hint field as below Image
There you can add Hint(Place holder) to EditText
Bit off-topic, but I use this:
template<typename T>
constexpr int sgn(const T &a, const T &b) noexcept{
return (a > b) - (a < b);
}
template<typename T>
constexpr int sgn(const T &a) noexcept{
return sgn(a, T(0));
}
and I found first function - the one with two arguments, to be much more useful from "standard" sgn(), because it is most often used in code like this:
int comp(unsigned a, unsigned b){
return sgn( int(a) - int(b) );
}
vs.
int comp(unsigned a, unsigned b){
return sgn(a, b);
}
there is no cast for unsigned types and no additional minus.
in fact i have this piece of code using sgn()
template <class T>
int comp(const T &a, const T &b){
log__("all");
if (a < b)
return -1;
if (a > b)
return +1;
return 0;
}
inline int comp(int const a, int const b){
log__("int");
return a - b;
}
inline int comp(long int const a, long int const b){
log__("long");
return sgn(a, b);
}
>>> my_list = ['this\n', 'is\n', 'a\n', 'list\n', 'of\n', 'words\n']
>>> map(str.strip, my_list)
['this', 'is', 'a', 'list', 'of', 'words']
With python >= 3.5
you can use mock_object.assert_not_called()
.
You can try this-
$('#selectID').append($('<option>',
{
value: value_variable,
text : text_variable
}));
Like this-
for (i = 0; i < 10; i++)_x000D_
{ _x000D_
$('#mySelect').append($('<option>',_x000D_
{_x000D_
value: i,_x000D_
text : "Option "+i _x000D_

Or try this-
$('#selectID').append( '<option value="'+value_variable+'">'+text_variable+'</option>' );
Like this-
for (i = 0; i < 10; i++)_x000D_
{ _x000D_
$('#mySelect').append( '<option value="'+i+'">'+'Option '+i+'</option>' );_x000D_

I recently had the same question, and coming from a Java world, I immediately started to search for a JSR 310 implementation for JavaScript. JSR 310 is a Date and Time API for Java (standard shipped as of Java 8). I think the API is very well designed.
Fortunately, there is a direct port to Javascript, called js-joda.
First, include js-joda in the <head>
:
<script
src="https://cdnjs.cloudflare.com/ajax/libs/js-joda/1.11.0/js-joda.min.js"
integrity="sha512-piLlO+P2f15QHjUv0DEXBd4HvkL03Orhi30Ur5n1E4Gk2LE4BxiBAP/AD+dxhxpW66DiMY2wZqQWHAuS53RFDg=="
crossorigin="anonymous"></script>
Then simply do this:
let date1 = JSJoda.LocalDate.of(2020, 12, 1);
let date2 = JSJoda.LocalDate.of(2021, 1, 1);
let daysBetween = JSJoda.ChronoUnit.DAYS.between(date1, date2);
Now daysBetween
contains the number of days between. Note that the end date is exclusive.
If you installed Node from their website, try this:
sudo rm -rf /usr/local/{bin/{node,npm},lib/node_modules/npm,lib/node,share/man/*/node.*}
This worked for me, but if you have any questions, my GitHub is 'mnafricano'.
To do links, you can do
.social h2 a:link {
color: pink;
font-size: 14px;
}
You can change the hover, visited, and active link styling too. Just replace "link" with what you want to style. You can learn more at the w3schools page CSS Links.
I'm using Maven 3+ version. In my case everything was fine. But while adding the M2_HOME along with bin directory, I missed the '\' at the end. Previously it was like: %M2_HOME%\bin , which was throwing the mvn not recognizable error. After adding "\" at the end, mvn started working fine. I guess "\" acts as pointer to next folder. "%M2_HOME%\bin\" Should work, if you missed it.
Yes, you need to close Connection
. Otherwise, the database client will typically keep the socket connection and other resources open.
if you are in the main you can do:
return 0;
or
exit(exit_code);
The exit code depends of the semantic of your code. 1 is error 0 e a normal exit.
In some other function of your program:
exit(exit_code)
will exit the program.
This is meant as more of historical information than a "real" answer.
Remember that back in the day you had LOTS of unix like operating systems whose designers all had their own notion of where to put stuff, and sometimes didn't include Python, Perl, Bash, or lots of other GNU/Open Source stuff at all.
This was even true of different Linux distributions. On Linux--pre-FHS[1]-you might have python in /usr/bin/ or /usr/local/bin/. Or it might not have been installed, so you built your own and put it in ~/bin
Solaris was the worst I ever worked on, partially as the transition from Berkeley Unix to System V. You could wind up with stuff in /usr/, /usr/local/, /usr/ucb, /opt/ etc. This could make for some really long paths. I have memories of the stuff from Sunfreeware.com installing each package in it's own directory, but I can't recall if it symlinked the binaries into /usr/bin or not.
Oh, and sometimes /usr/bin was on an NFS server[2].
So the env
utility was developed to work around this.
Then you could write #!/bin/env interpreter
and as long as the path was proper things had a reasonable chance of running. Of course, reasonable meant (for Python and Perl) that you had also set the appropriate environmental variables. For bash/ksh/zsh it just worked.
This was important because people were passing around shell scripts (like perl and python) and if you'd hard coded /usr/bin/python on your Red Hat Linux workstation it was going to break bad on a SGI...well, no, I think IRIX put python in the right spot. But on a Sparc station it might not run at all.
I miss my sparc station. But not a lot. Ok, now you've got me trolling around on E-Bay. Bastages.

Use a negative lookahead and a negative lookbehind:
> s = "one two 3.4 5,6 seven.eight nine,ten"
> parts = re.split('\s|(?<!\d)[,.](?!\d)', s)
['one', 'two', '3.4', '5,6', 'seven', 'eight', 'nine', 'ten']
In other words, you always split by \s
(whitespace), and only split by commas and periods if they are not followed (?!\d)
or preceded (?<!\d)
by a digit.
DEMO.
EDIT: As per @verdesmarald comment, you may want to use the following instead:
> s = "one two 3.4 5,6 seven.eight nine,ten,1.2,a,5"
> print re.split('\s|(?<!\d)[,.]|[,.](?!\d)', s)
['one', 'two', '3.4', '5,6', 'seven', 'eight', 'nine', 'ten', '1.2', 'a', '5']
This will split "1.2,a,5"
into ["1.2", "a", "5"]
.

Add the maven repository outside the buildscript
configuration block of your main build.gradle
file as follows:

Make sure that you add them after the following:
apply plugin: 'com.android.application'
Unfortunately, np.polynomial.polynomial.polyfit
returns the coefficients in the opposite order of that for np.polyfit
and np.polyval
(or, as you used np.poly1d
). To illustrate:
In [40]: np.polynomial.polynomial.polyfit(x, y, 4)
Out[40]:
array([ 84.29340848, -100.53595376, 44.83281408, -8.85931101,
0.65459882])
In [41]: np.polyfit(x, y, 4)
Out[41]:
array([ 0.65459882, -8.859311 , 44.83281407, -100.53595375,
84.29340846])
In general: np.polynomial.polynomial.polyfit
returns coefficients [A, B, C]
to A + Bx + Cx^2 + ...
, while np.polyfit
returns: ... + Ax^2 + Bx + C
.
So if you want to use this combination of functions, you must reverse the order of coefficients, as in:
ffit = np.polyval(coefs[::-1], x_new)
However, the documentation states clearly to avoid np.polyfit
, np.polyval
, and np.poly1d
, and instead to use only the new(er) package.
You're safest to use only the polynomial package:
import numpy.polynomial.polynomial as poly
coefs = poly.polyfit(x, y, 4)
ffit = poly.polyval(x_new, coefs)
plt.plot(x_new, ffit)
Or, to create the polynomial function:
ffit = poly.Polynomial(coefs) # instead of np.poly1d
plt.plot(x_new, ffit(x_new))

WARNING: Using
Access-Control-Allow-Origin: *
can make your API/website vulnerable to cross-site request forgery (CSRF) attacks. Make certain you understand the risks before using this code.
It's very simple to solve if you are using PHP. Just add the following script in the beginning of your PHP page which handles the request:
<?php header('Access-Control-Allow-Origin: *'); ?>
If you are using Node-red you have to allow CORS in the node-red/settings.js
file by un-commenting the following lines:
// The following property can be used to configure cross-origin resource sharing

If you are using Flask same as the question; you have first to install flask-cors
$ pip install -U flask-cors
Then include the Flask cors in your application.
from flask_cors import CORS
A simple application will look like:
from flask import Flask
from flask_cors import CORS
app = Flask(__name__)
CORS(app)
@app.route("/")
def helloWorld():
return "Hello, cross-origin-world!"
For more details, you can check the Flask documentation.

Put your text cursor again on the method and click menu Navigate ? Open Implementation. Now if you have more than one implementation of the method, you will get choice to pick which implementation to open.
By defining a keybinding on Preferences ? General ? Keys you can even use the feature easier, but before you do that, see if this shortcut is fast enough for you.
Press Ctrl + click and hold. Now move your mouse over the same method. Tadam… you will get choice.
If you pick Open Implementation you’ll get the same choice as before.

If you're using jQuery (or don't mind adding it), this will get the job done better than any of these hacks.
function getMaxColCount($table) {
var maxCol = 0;
$table.find('tr').each(function(i,o) {
var colCount = 0;
$(o).find('td:not(.maxcols),th:not(.maxcols)').each(function(i,oo) {
var cc = Number($(oo).attr('colspan'));
if (cc) {
colCount += cc;
} else {
colCount += 1;
}
});
if(colCount > maxCol) { maxCol = colCount };
});
return maxCol;
}
To ease the implementation, I decorate any td/th I need adjusted with a class such as "maxCol" then I can do the following:
$('td.maxcols, th.maxcols').each(function(i,o) {
$t = $($(o).parents('table')[0]); $(o).attr('colspan', getMaxColCount($t));
});
If you find an implementation this won't work for, don't slam the answer, explain in comments and I'll update if it can be covered.
You could use a sub query...
WHERE t1.field3 = (SELECT MAX(st1.field3) FROM table1 AS st1)
But I would actually move this out of the where clause and into the join statement, as an AND for the ON clause.
Do you want to find elements that contain "match", or that equal "match"?
This will find elements that have text nodes that equal 'match' (matches none of the elements because of leading and trailing whitespace in random2
):
//*[text()='match']
This will find all elements that have text nodes that equal "match", after removing leading and trailing whitespace(matches random2
):
//*[normalize-space(text())='match']
This will find all elements that contain 'match' in the text node value (matches random2
and random3
):
//*[contains(text(),'match')]
This XPATH 2.0 solution uses the matches()
function and a regex pattern that looks for text nodes that contain 'match' and begin at the start of the string(i.e. ^
) or a word boundary (i.e. \W
) and terminated by the end of the string (i.e. $
) or a word boundary. The third parameter i
evaluates the regex pattern case-insensitive. (matches random2
)
//*[matches(text(),'(^|\W)match($|\W)','i')]
Use a CountDownLatch:

} catch (InterruptedException E) {
// handle
}
and within your task (enclose in try / finally)
latch.countDown();

I'm using Python 3.6 and MacOS. I have uninstalled and installed with pip3 install bs4
but that didn't work. It seems like python is not able to detect or search the bs4

This is what worked:
python3 -m pip install bs4
The -m
option allows you to add a module name.
Huffman Coding might help, but only if you have a lot of frequent characters in your small String
int dp1 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 1,
context.getResources().getDisplayMetrics());
tv.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
dp1 * 100)); // if you want to set layout height to 100dp
llview.addView(tv);
Within Crystal, you can do it by creating a formula that uses the ToNumber
function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:
If NumericText ({field}) then ToNumber ({field}) else 0
Alternatively, you might find it easier to convert the field's datatype within the query used in the report.
Add this function to your helper file and simply call.
function getRawQuery($sql){
$query = str_replace(array('?'), array('\'%s\''), $sql->toSql());
$query = vsprintf($query, $sql->getBindings());
return $query;
}
Output: "select * from user where status = '1' order by id desc limit 25 offset 0"
Notepad++ provides 2 types of features:
Based on what you write, it seems what you want is auto-completion on function only + suggestion on arguments.
To do that, you just need to change a setting.
Settings
> Preferences...
> Auto-completion
Enable Auto-completion on each input
Function completion
and not Word completion
Function parameter hint on input
(if you have this option)On version 6.5.5 of Notepad++, I have this setting
Some documentation about auto-completion is available in Notepad++ Wiki.
In case you have a multi-module project :
let us say your module structure is
root-module
-> a-module
-> b-module
and the test(testToRun) you are looking to run is in b-module, with full path : com.xyz.b.module.TestClass.testToRun
As here you are interested to run the test in b-module, so you should see the tasks available for b-module.
./gradlew :b-module:tasks
The above command will list all tasks in b-module with description. And in ideal case, you will have a task named test to run the unit tests in that module.
./gradlew :b-module:test
Now, you have reached the point for running all the tests in b-module, finally you can pass a parameter to the above task to run tests which matches the certain path pattern
./gradlew :b-module:test --tests "com.xyz.b.module.TestClass.testToRun"
Now, instead of this if you run
./gradlew test --tests "com.xyz.b.module.TestClass.testToRun"
It will run the test task for both module a and b, which might result in failure as there is nothing matching the above pattern in a-module.
EDIT: As mentioned by Stephen Niedzielski in his comment, the issue seems to come from the 32-bit being of the JRE, which is de facto, looking for the 32-bit version of libXtst6
. To install the required version of the library:
$ sudo apt-get install libxtst6:i386
Type:
$ sudo apt-get update
$ sudo apt-get install libxtst6
If this isn’t OK, type:
$ sudo updatedb
$ locate libXtst
it should return something like:
/usr/lib/x86_64-linux-gnu/libXtst.so.6 # Mine is OK
/usr/lib/x86_64-linux-gnu/libXtst.so.6.1.0
If you do not have libXtst.so.6
but do have libXtst.so.6.X.X
create a symbolic link:
$ cd /usr/lib/x86_64-linux-gnu/
$ ln -s libXtst.so.6 libXtst.so.6.X.X
Hope this helps.
I was having the same problem until I read Jon Skeet's answer about the debugger displaying a single backslash with a double backslash even though the string may have a single backslash. I was not aware of that. So I changed my code from
text2 = text1.Replace(@"\\", @"/");
to
text2 = text1.Replace(@"\", @"/");
and that solved the problem. Note: I'm interfacing and R.Net which uses single forward slashes in path strings.
I'd think some datbases can import data from CSV (comma separated values) files, wich you can export from exel. Or at least it's quite easy to use a csv parser (find one for your language, don't try to create one yourself - it's harder than it looks) to import it to the database.
I'm not familiar with MS SQL but it wouldn't suprise me if it does support it directly.
In any case I think the requrement must be that the structure in the Exel sheet and the database table is similar.
I'd use JSON as the format and Ajax (really XMLHttpRequest) as the client->server mechanism.
Ideally, you would create a method on the choice object that found itself in votes, or create a relationship between the models. A template tag that performed the dictionary lookup would work, too.
I know as for Appium Mobile Automation you need .app file to run ios app on Simulator.So as like me many of you face this problem. So I explain how to create that .app file and where it is located.
1.Open Xcode.
2.Click on your sample project.(If you don't have then click on create new xcode project)
3.In left panel inside screen you will see products folder then click and expand that, you will see the list.
When dealing with mocking lists and iterating them, I always use something like:
@Spy
private List<Object> parts = new ArrayList<>();
This is probably a good starting point (version 8.4+ only):
SELECT id_field, array_agg(value_field1), array_agg(value_field2)
FROM data_table
GROUP BY id_field
array_agg returns an array, but you can CAST that to text and edit as needed (see clarifications, below).
Prior to version 8.4, you have to define it yourself prior to use:
CREATE AGGREGATE array_agg (anyelement)
(
sfunc = array_append,
stype = anyarray,
initcond = '{}'
);
(paraphrased from the PostgreSQL documentation)
Clarifications:
To use the Bash builtin time
rather than /bin/time
you can set this variable:
TIMEFORMAT='%3R'
which will output the real time that looks like this:
5.009
or
65.233
The number specifies the precision and can range from 0 to 3 (the default).
You can use:
TIMEFORMAT='%3lR'
to get output that looks like:
3m10.022s
The l

In case you don't want to use the M2_HOME and want to direct the IntelliJ to the maven installation you can simply set it by:
A better way is to have a symlink e.g. 'latest' for the latest version and point your IntelliJ to use that for consistency, given latest points to the latest version of maven installed on your box.
INSERT INTO table (a,b) VALUES (1,2), (2,3), (3,4);
Make sure your escaping the HTML characters
E.g.
// Always check an input variable is set before you use it
if (isset($_POST['contact_list'])) {
// Escape any html characters
echo htmlentities($_POST['contact_list']);
}
This would occur because of the angle brackets and the browser thinking they are tags.
Instead of using interop you can use the .NET FileStream class methods Lock and Unlock:

Building on Roland's answer, using tidyr
to reshape the data from wide to long:
library(tidyr)
library(ggplot2)
df <- read.table(text="Rank F1 F2 F3
1 500 250 50
2 400 100 30
3 300 155 100
4 200 90 10", header=TRUE)
df %>%
gather(variable, value, F1:F3) %>%
ggplot(aes(x = Rank, y = value, fill = variable)) +
geom_bar(stat = "identity")
As a more general solution (but ASCII only!), to include any other separators between words (like commas and semicolons), I suggest:
String s = "I want to walk my dog, cat, and tarantula; maybe even my tortoise.";
String[] words = s.split("\\W+");
The regex means that the delimiters will be anything that is not a word [\W], in groups of at least one [+]. Because [+] is greedy, it will take for instance ';' and ' ' together as one delimiter.
I would suggest using something clearer (especially thinking to who will have to maintain the code)... what about:
var formats = "(999)999-9999|999-999-9999|9999999999";
var r = RegExp("^(" +
formats
.replace(/([\(\)])/g, "\\$1")
.replace(/9/g,"\\d") +
")$");
where the regexp is built from a clear template ? Adding a new one would then be a no-brainer and may be even the customer itself could be able to do that in a "options" page.
The others are right about making the driver JAR available to your servlet container. My comment was meant to suggest that you verify from the command line whether the driver itself is intact.
Rather than an empty main()
, try something like this, adapted from the included documentation:
public class LoadDriver {
public static void main(String[] args) throws Exception {
Class.forName("com.mysql.jdbc.Driver");
}
}
On my platform, I'd do this:
$ ls mysql-connector-java-5.1.12-bin.jar mysql-connector-java-5.1.12-bin.jar $ javac LoadDriver.java $ java -cp mysql-connector-java-5.1.12-bin.jar:. LoadDriver
On your platform, you need to use ;
as the path separator, as discussed here and here.
Adding
android.useAndroidX=true
android.enableJetifier=true
to gradle.properties worked for me.
You can do the following:
String [] strings = new String [] {"1", "2" };
List<String> stringList = new ArrayList<String>(Arrays.asList(strings)); //new ArrayList is only needed if you absolutely need an ArrayList
You've already done it correctly by using a DateTime
parameter with the value from the DateTime
, so it should already work. Forget about ToString()
- since that isn't used here.
If there is a difference, it is most likely to do with different precision between the two environments; maybe choose a rounding (seconds, maybe?) and use that. Also keep in mind UTC/local/unknown (the DB has no concept of the "kind" of date; .NET does).
I have a table and the date-times in it are in the format:
2011-07-01 15:17:33.357
Note that datetimes in the database aren't in any such format; that is just your query-client showing you white lies. It is stored as a number (and even that is an implementation detail), because humans have this odd tendency not to realise that the date you've shown is the same as 40723.6371916281
. Stupid humans. By treating it simply as a "datetime" throughout, you shouldn't get any problems.
$elements_array = ['first', 'second'];
function to remove some array elements
function remove($arr, $data) {
return array_filter($arr, function ($element) use ($data) {
return $element != $data;
});
}
call and print
print_r(remove($elements_array, 'second'));
the result
Array ( [0] => first )
To understand the use of "SET SERVEROUTPUT ON" I will take an example
DECLARE
a number(10) :=10;
BEGIN
dbms_output.put_line(a) ;
dbms_output.put_line('Hello World ! ') ;
END ;
With an output : PL/SQl procedure successfully completed i.e without the expected output
And the main reason behind is that ,whatever we pass inside dbms_output.put_line(' ARGUMENT '/VALUES) i.e. ARGUMENT/VALUES , is internally stored inside a buffer in SGA(Shared Global Area ) memory area upto 2000 bytes .
*NOTE :***However one should note that this buffer is only created when we use **dbms_output package. And we need to set the environment variable only once for a session !!
And in order to fetch it from that buffer we need to set the environment variable for the session . It makes a lot of confusion to the beginners that we are setting the server output on ( because of its nomenclature ) , but unfortunately its nothing like that . Using SET SERVER OUTPUT ON are just telling the PL/SQL engine that
*Hey please print the ARGUMENT/VALUES that I will be passing inside dbms_output.put_line
and in turn PL/SQl run time engine prints the argument on the main console .
I think I am clear to you all . Wish you all the best . To know more about it with the architectural structure of Oracle Server Engine you can see my answer on Quora http://qr.ae/RojAn8
And to answer your question "One should use SET SERVER OUTPUT in the beginning of the session. "

Additionally, DataContractSerializer will serialize items marked as [Serializable] and will also serialize unmarked types in .NET 3.5 SP1 and later, to allow support for serializing anonymous types.
So, it depends on how you've decorated your class as to how to keep a member from serializing:
[DataContract]
, then remove the [DataMember]
for the property.[Serializable]
, then add [NonSerialized]
in front of the field for the property.[IgnoreDataMember]
to the property.Depending on your definition of shortly, you could use one of the following options:
try: int(your_input); except ValueError: # ...
your_input.isdigit()
parse
which is kind of the opposite of format
This Solution is of O(n^2) complexity. O(1) is the space complexity.

The documentation says that there only one context variable, form
.
If you're having trouble with login (which is common), the documentation says there are three context variables:
form
: A Form object representing the login form. See the forms documentation for more on Form objects.next
: The URL to redirect to after successful login. This may contain a query string, too.site_name
: The name of the current Site, according to the SITE_ID setting.I found this post in google as the second top result, first was using exec :(
Anyway, while this did not suite my needs exactly.. I decided to post an answer for others with my quick but extended version of this.
SCRIPT FEATURES
Anyway, onto the script.. While it may look like a lot.. Remember there is excess in here.. So feel free to delete the reporting sections as needed...
Also it may look messy as well and certain things could be cleaned up easily... So dont comment about it, its just a quick script with basic comments thrown in.. NOT FOR LIVE USE.. But easy to clean up for live use!
In this example, it is run from a directory that is inside of the root www / public_html folder.. So only needs to travel up one folder to get to the root.

WHAT DOES IT DO??
It will simply zip the complete contents of the variable $pathBase and store the zip in that same folder. It does a simple detection for previous backups and skips them.
CRON BACKUP
This script i've just tested on linux and worked fine from a cron job with using an absolute url for the pathBase.
FacebookConnect or OpenID are two great options.
Basically, your users login to other sites they are already members of (Facebook, or Google), and then you get confirmation from that site telling you the user is trustworthy - start a session, and they're logged in. No database needed (unless you want to associate more data to their account).
If you can make use of equals
, then filter the list by using distinct
within a stream (see answers above). If you can not or don't want to override the equals
method, you can filter
the stream in the following way for any property, e.g. for the property Name (the same for the property Id etc.):
Set<String> nameSet = new HashSet<>();
List<Employee> employeesDistinctByName = employees.stream()
.filter(e -> nameSet.add(e.getName()))
.collect(Collectors.toList());
# remove all objects but selected
rm(list = ls()[which("key_function" != ls())])
Did you try du -ks | awk '{print $1*1024}'. That might just work.
Just need to add version of which you want
upgrade or downgrade
npm install -g npm@version
Example if you want to downgrade from npm 5.6.0 to 4.6.1 then,
npm install -g [email protected]
It is tested on linux
with a specific dir:
cd your_dir && curl -L https://download.calibre-ebook.com/3.19.0/calibre-3.19.0-x86_64.txz | tar zx
In date '?'
, the '?'
is a literal string with value ?
, not a parameter placeholder, so your query does not have any parameters. The date
is a shorthand cast from (literal) string to date. You need to replace date '?'
with ?
to actually have a parameter.
Also if you know it is a date, then use setDate(..)
and not setString(..)
to set the parameter.
If you want to put the routes in a separate file, for example routes.js
, you can create the routes.js
file in this way:
module.exports = function(app){
app.get('/login', function(req, res){
res.render('login', {
title: 'Express Login'
});
});
//other routes..
}
And then you can require it from app.js
passing the app
object in this way:
require('./routes')(app);
Have also a look at these examples
https://github.com/visionmedia/express/tree/master/examples/route-separation
From the MS SQL Server online documentation (http://technet.microsoft.com/en-us/library/ms186734.aspx ), here is their example that I have tested and works, for retrieving a specific set of rows. ROW_NUMBER requires an OVER, but you can order by whatever you like:
WITH OrderedOrders AS
(
SELECT SalesOrderID, OrderDate,
ROW_NUMBER() OVER (ORDER BY OrderDate) AS RowNumber
FROM Sales.SalesOrderHeader
)
SELECT SalesOrderID, OrderDate, RowNumber
FROM OrderedOrders
WHERE RowNumber BETWEEN 50 AND 60;
I think an example of the case that has caught me by surprise is relevant:
var myObject = { name: "Cody", status: "Surprised" };
for (var propertyName in myObject) {
document.writeln( propertyName + " : " + myObject[propertyName] );
}
But to my surprise, the output is
name : Cody
status : Surprised
forEach : function (obj, callback) {
for (prop in obj) {
if (obj.hasOwnProperty(prop) && typeof obj[prop] !== "function") {
callback(prop);
}
}
}
Why? Another script on the page has extended the Object prototype:
Object.prototype.forEach = function (obj, callback) {
for ( prop in obj ) {
if ( obj.hasOwnProperty( prop ) && typeof obj[prop] !== "function" ) {
callback( prop );
}
}
};
No. You can't send headers after they were sent. Try to use hooks in wordpress
You can use a <div>
to cover the scrollbar if you really want it to disappear.
Although it won't work on IE6, modern browsers do let you put a <div>
on top of it.
The easiest way I found (just I use eval() to convert string gotten from input to tuple to read again for form instance or other place)
This trick works very well
#model.py
class ClassName(models.Model):
field_name = models.CharField(max_length=100)
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
if self.field_name:
self.field_name= eval(self.field_name)
#form.py
CHOICES = [('pi', 'PI'), ('ci', 'CI')]
class ClassNameForm(forms.ModelForm):
field_name = forms.MultipleChoiceField(choices=CHOICES)
class Meta:
model = ClassName
fields = ['field_name',]
You can use matplotlib for this. matplotlib has a mplot3d module that will do exactly what you want.
from matplotlib import pyplot
from mpl_toolkits.mplot3d import Axes3D
import random
fig = pyplot.figure()
ax = Axes3D(fig)
sequence_containing_x_vals = list(range(0, 100))
sequence_containing_y_vals = list(range(0, 100))
sequence_containing_z_vals = list(range(0, 100))
random.shuffle(sequence_containing_x_vals)
random.shuffle(sequence_containing_y_vals)
random.shuffle(sequence_containing_z_vals)
ax.scatter(sequence_containing_x_vals, sequence_containing_y_vals, sequence_containing_z_vals)
pyplot.show()
The code above generates a figure like:
Actually, you could simply set splash Activity
with NoActionBar
and set your main activity
with action bar.
As far as I can tell what you could do is "retire" your previous app and redirect all users to your new app. This procedure is not supported by Google (tsk... tsk...), but it could be implemented in four steps:
Change the current application to show a message to the users about the upgrade and redirect them to the new app listing. Probably a full screen message would do with some friendly text. This message could be triggered remotely ideally, but a cut-off date can be used too. (But then that will be a hard deadline for you, so be careful... ;))
Release the modified old app as an upgrade, maybe with some feature upgrades/bug fixes too, to "sweeten the deal" to the users. Still there is no guarantee that all users will upgrade, but probably the majority will do.
Prepare your new app with the updated package name and upload it to the store, then trigger the message in the old app (or just wait until it expires, if that was your choice).
Unpublish the old app in Play Store to avoid any new installs. Unpublishing an app doesn't mean the users who already installed it won't have access to it anymore, but at least the potential new users won't find it on the market.
Not ideal and can be annoying to the users, sometimes even impossible to implement due to the status/possibilities of the app. But since Google left us no choice this is the only way to migrate the users of the old apps to a "new" one (even if it is not really new). Not to mention that if you don't have access to the sources and code signing details for the old app then all you could do is hoping that he users will notice the new app...
If anybody figured out a better way by all means: please do tell.
you could also grep the line out and then cut it like for instance:
grep 'text' filename | cut -c 1-5
I dealed with this issue today and upgrading my webdrivermanger solved it for me (My previous version was 3.0.0):
<dependency>
<groupId>io.github.bonigarcia</groupId>
<artifactId>webdrivermanager</artifactId>
<version>3.3.0</version>
<scope>test</scope>
</dependency>
Computed could be consider has a function. So for an exemple on valdiation you could clearly do something like :
methods: {
validation(attr){
switch(attr) {
case 'email':
const re = /^(([^<>()\[\]\.,;:\s@\"]+(\.[^<>()\[\]\.,;:\s@\"]+)*)|(\".+\"))@(([^<>()[\]\.,;:\s@\"]+\.)+[^<>()[\]\.,;:\s@\"]{2,})$/i;
return re.test(this.form.email);
case 'password':
return this.form.password.length > 4
}
},
...
}
Which you'll be using like :
<b-form-input
id="email"
v-model="form.email"
type="email"
:state="validation('email')"
required
placeholder="Enter email"
></b-form-input>
Just keep in mind that you will still miss the caching specific to computed.
The optimiser will judge if the use of your index will make your query run faster, and if it is, it will use the index.
Depending on your RDBMS you can force the use of an index, although it is not recommended unless you know what you are doing.
In general you should index columns that you use in table join's and where statements
REST is a software design pattern typically used for web applications. In layman's terms this means that it is a commonly used idea used in many different projects. It stands for REpresentational State Transfer. The basic idea of REST is treating objects on the server-side (as in rows in a database table) as resources than can be created or destroyed.
The most basic way of thinking about REST is as a way of formatting the URLs of your web applications. For example, if your resource was called "posts", then:
/posts
Would be how a user would access ALL the posts, for displaying.
/posts/:id
Would be how a user would access and view an individual post, retrieved based on their unique id.
/posts/new
Would be how you would display a form for creating a new post.
Sending a POST request to /users
would be how you would actually create a new post on the database level.
Sending a PUT request to /users/:id
would be how you would update the attributes of a given post, again identified by a unique id.
Sending a DELETE request to /users/:id
would be how you would delete a given post, again identified by a unique id.
As I understand it, the REST pattern was mainly popularized (for web apps) by the Ruby on Rails framework, which puts a big emphasis on RESTful routes. I could be wrong about that though.
I may not be the most qualified to talk about it, but this is how I've learned it (specifically for Rails development).
When someone refers to a "REST api," generally what they mean is an api that uses RESTful urls for retrieving data.
simple approach:
List<int>[] a = new List<int>[100];
for (int i = 0; i < a.Length; i++)
{
a[i] = new List<int>();
}
or LINQ
approach
var b = Enumerable.Range(0,100).Select((i)=>new List<int>()).ToArray();
Martijen's answer makes sense, but it was missing something crucial that may seem obvious to others but was hard for me to figure out.
In the version where you use argparse, you need to have this line in the main body.
args = parser.parse_args(args)
Normally when you are using argparse just in a script you just write
args = parser.parse_args()
and parse_args find the arguments from the command line. But in this case the main function does not have access to the command line arguments, so you have to tell argparse what the arguments are.
Here is an example
import argparse
import sys
def x(x_center, y_center):
print "X center:", x_center
print "Y center:", y_center
def main(args):
parser = argparse.ArgumentParser(description="Do something.")
parser.add_argument("-x", "--xcenter", type=float, default= 2, required=False)
parser.add_argument("-y", "--ycenter", type=float, default= 4, required=False)
args = parser.parse_args(args)
x(args.xcenter, args.ycenter)
if __name__ == '__main__':
main(sys.argv[1:])
Assuming you named this mytest.py To run it you can either do any of these from the command line
python ./mytest.py -x 8
python ./mytest.py -x 8 -y 2
python ./mytest.py
which returns respectively
X center: 8.0
Y center: 4
or
X center: 8.0
Y center: 2.0
or
X center: 2
Y center: 4
Or if you want to run from another python script you can do
import mytest
mytest.main(["-x","7","-y","6"])
which returns
X center: 7.0
Y center: 6.0
Look up the new HTML5 Input Types. These instruct browsers to perform client-side filtering of data, but the implementation is incomplete across different browsers. The pattern
attribute will do regex-style filtering, but, again, browsers don't fully (or at all) support it.
However, these won't block the input itself, it will simply prevent submitting the form with the invalid data. You'll still need to trap the onkeydown
event to block key input before it displays on the screen.
At the time when this question was asked there wasn't another function in Pandas to test equality, but it has been added a while ago: pandas.equals
You use it like this:
df1.equals(df2)
Some differenes to ==

to be considered equal, see this stackoverflow questionYou can't run 16-bit applications (or components) on 64-bit versions of Windows. That emulation layer no longer exists. The 64-bit versions already have to provide a compatibility layer for 32-bit applications.
Support for 16-bit had to be dropped eventually, even in a culture where backwards-compatibility is of sacred import. The transition to 64-bit seemed like as good a time as any. It's hard to imagine anyone out there in the wild that is still using 16-bit applications and seeking to upgrade to 64-bit OSes.
What would be the best way to get round this problem?
If the component itself is 16-bit, then using a virtual machine running a 32-bit version of Windows is your only real choice. Oracle's VirtualBox is free, and a perennial favorite.
If only the installer is 16-bit (and it installs a 32-bit component), then you might be able to use a program like 7-Zip to extract the contents of the installer and install them manually. Let's just say this "solution" is high-risk and you should have few, if any, expectations.
It's high time to upgrade away from 16-bit stuff, like Turbo C++ and Sheridan controls. I've yet to come across anything that the Sheridan controls can do that the built-in controls can't do and haven't been able to do since Windows 95.
Use display:none/block
, instead of visibility
, and add a margin-top/bottom
for the space you want to see ONLY when the inputs are shown
function yesnoCheck() {
if (document.getElementById('yesCheck').checked) {
document.getElementById('ifYes').style.display = 'block';
} else {
document.getElementById('ifYes').style.display = 'none';
}
}
and your HTML line for the ifYes
tag
<div id="ifYes" style="display:none;margin-top:3%;">If yes, explain:
If you have similar issues in Intellij do as others said above me :
And you are done.!!
You will need two things. The first is @media screen
to activate the specific code at a certain screen size, used for responsive design. The second is the use of the visibility: hidden
attribute. Once the browser/screen reaches 600pixels then #title_message
will become hidden.
@media screen and (max-width: 600px) {
#title_message {
visibility: hidden;
clear: both;
float: left;
margin: 10px auto 5px 20px;
width: 28%;
display: none;
}
}
EDIT: if you are using another CSS for mobile then just add the visibility: hidden;
to #title_message
. Hope this helps you!

sys.path
is only searched for Python modules. For dynamic linked libraries, the paths searched must be in LD_LIBRARY_PATH
. Check if your LD_LIBRARY_PATH
includes /usr/local/lib
, and if it doesn't, add it and try again.
Some more information (source):
In Linux, the environment variable LD_LIBRARY_PATH is a colon-separated set of directories where libraries should be searched for first, before the standard set of directories; this is useful when debugging a new library or using a nonstandard library for special purposes. The environment variable LD_PRELOAD lists shared libraries with functions that override the standard set, just as /etc/ld.so.preload does. These are implemented by the loader /lib/ld-linux.so. I should note that, while LD_LIBRARY_PATH works on many Unix-like systems, it doesn't work on all; for example, this functionality is available on HP-UX but as the environment variable SHLIB_PATH, and on AIX this functionality is through the variable LIBPATH (with the same syntax, a colon-separated list).
Update: to set LD_LIBRARY_PATH
, use one of the following, ideally in your ~/.bashrc
or equivalent file:
export LD_LIBRARY_PATH=/usr/local/lib
or
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
Use the first form if it's empty (equivalent to the empty string, or not present at all), and the second form if it isn't. Note the use of export.
There are two ways to doing the same:
You may set the value of android:divider="#FFCCFF" in layout xml file. With this you also have to specify height of divider like this android:dividerHeight="5px".
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="@+id/lvMyList"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#FFCCFF"
android:dividerHeight="5px"/>
</LinearLayout>
You may also do this by programmatically...
ListView listView = getListView();
ColorDrawable myColor = new ColorDrawable(
this.getResources().getColor(R.color.myColor)
);
listView.setDivider(myColor);
listView.setDividerHeight();
As far as I know it's not possible... but you can try something like this:
.underline _x000D_
{_x000D_
color: blue;_x000D_
border-bottom: 1px solid red;_x000D_
}
_x000D_
<div>_x000D_
<span class="underline">hello world</span>_x000D_
</div>
_x000D_
This ought to do the trick: just limit the result to 1 row; if a row comes back the $lectureName
is Assigned, otherwise it's Available.
function checkLectureStatus($lectureName)
{
$con = connectvar();
mysql_select_db("mydatabase", $con);
$result = mysql_query(
"SELECT * FROM preditors_assigned WHERE lecture_name='$lectureName' LIMIT 1");
if(mysql_fetch_array($result) !== false)
return 'Assigned';
return 'Available';
}
Loop through the dictionary to find the index and then remove it.
I had this issue on the server I was deploying to, and determined that I did not need
Microsoft.CodeDom.Providers.DotNetCompilerPlatform
So, I uninstalled it via nuget, and removed the reference in the web config. No more issues.
I originally tried to added target node to the .proj file as mentioned in some of the other answers, but that just lead to another error where the msbuild
could not copy the pagefile.sys
which seemed from what I read to be a bug in the nuget package.
There are multiple solutions for this. If you want the page to be refreshed you actually don't need JavaScript, the browser can do it for you if you add this meta
tag in your head
tag.
<meta http-equiv="refresh" content="30">
The browser will then refresh the page every 30 seconds.
If you really want to do it with JavaScript, then you can refresh the page every 30 seconds with location.reload()
(docs) inside a setTimeout()
:
window.setTimeout(function () {
window.location.reload();
}, 30000);
If you don't need to refresh the whole page but only a part of it, I guess an Ajax call would be the most efficient way.
I was having problem that control was not going in to didselect row after applying break point. problem was in view. I removed tab gesture from view. then its worked fine
You may directly right-click on the table name - that also shows the "Import Data.." option.Then you can follow few simple steps & succeed.
Do anyone know how to import a new table with data from excel?
The coalesce() is the best solution when there are multiple columns [and]/[or] values and you want the first one. However, looking at books on-line, the query optimize converts it to a case statement.
MSDN excerpt
The COALESCE expression is a syntactic shortcut for the CASE expression.
That is, the code COALESCE(expression1,...n) is rewritten by the query optimizer as the following CASE expression:
CASE
WHEN (expression1 IS NOT NULL) THEN expression1
WHEN (expression2 IS NOT NULL) THEN expression2
...
ELSE expressionN
END
With that said, why not a simple ISNULL()? Less code = better solution?
Here is a complete code snippet.
-- drop the test table
drop table #temp1
go
-- create test table
create table #temp1
(
issue varchar(100) NOT NULL,
total_amount int NULL
);
go
-- create test data
insert into #temp1 values
('No nulls here', 12),
('I am a null', NULL);
go
-- isnull works fine
select
isnull(total_amount, 0) as total_amount
from #temp1
Last but not least, how are you getting null values into a NOT NULL column?
I had to change the table definition so that I could setup the test case. When I try to alter the table to NOT NULL, it fails since it does a nullability check.
-- this alter fails
alter table #temp1 alter column total_amount int NOT NULL
There are a couple of options there. The sample code is in Java, but a port to other languages should be straightforward.
WebElement myElement = driver.findElement(By.id("myDiv"));
WebElement parent = (WebElement) ((JavascriptExecutor) driver).executeScript(
"return arguments[0].parentNode;", myElement);
WebElement myElement = driver.findElement(By.id("myDiv"));
WebElement parent = myElement.findElement(By.xpath("./.."));
WebElement
Note: As you can see, for the JavaScript version you'll need the driver
. If you don't have direct access to it, you can retrieve it from the WebElement
using:
WebDriver driver = ((WrapsDriver) myElement).getWrappedDriver();
Plotly is missing in this list. I've linked the python binding page. It definitively has animated and interative 3D Charts. And since it is Open Source most of that is available offline. Of course it is working with Jupyter
Why is MichalBE getting downvoted? He's right - using jQuery (or any library) just to fire a function on page load is overkill, potentially costing people money on mobile connections and slowing down the user experience. If the original poster doesn't want to use onload in the body tag (and he's quite right not to), add this after the draw() function:
if (draw) window.onload = draw;
Or this, by Simon Willison, if you want more than one function to be executed:
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function() {
if (oldonload) {
oldonload();
}
func();
}
}
}

On iOS there is the switch UI component instead of a checkbox, look into the UISwitch

Android 8 introduced a new requirement of setting the channelId

bigText.bigText(verseurl);
bigText.setBigContentTitle("Today's Bible Verse");
bigText.setSummaryText("Text in detail");
mBuilder.setContentIntent(pendingIntent);
mBuilder.setSmallIcon(R.mipmap.ic_launcher_round);
mBuilder.setContentTitle("Your Title");
mBuilder.setContentText("Your text");
mBuilder.setPriority(Notification.PRIORITY_MAX);
mBuilder.setStyle(bigText);
mNotificationManager =
(NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
// === Removed some obsoletes
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
{
String channelId = "Your_channel_id";
NotificationChannel channel = new NotificationChannel(
channelId,
"Channel human readable title",
NotificationManager.IMPORTANCE_HIGH);
mNotificationManager.createNotificationChannel(channel);
mBuilder.setChannelId(channelId);
}
mNotificationManager.notify(0, mBuilder.build());
In HTML:
<a href="index.php?link=home" name="home">home</a>
Then in PHP:
if(isset($_GET['link'])){$_SESSION['link'] = $_GET['link'];}
Instinctively one thinks geometrically: horizontal (X) axis and then vertical (Y) axis. This is not, however, the case with a 2D array, rows come first and then columns.
Consider the following analogy: in geometry one walks to the ladder (X axis) and climbs it (Y axis). Conversely, in Java one descends the ladder (rows) and walks away (columns).

Are you sure a core dump is what you want here? That will contain the raw guts of the running JVM, rather than java-level information. Perhaps a JVM heap dump is more what you need.

If you're using Laravel, my problem was in the name of my Route. Instead:
Route::put('/reason/update', 'REASONController@update');
I wrote:
Route::put('/reason/update', 'RESONController@update');
and when I fixed the controller name, the code worked!

You can just try to download data, and if connection fail you will know that somethings with connection isn't fine.
Basically you can't check if computer is connected to internet. There can be many reasons for failure, like wrong DNS configuration, firewalls, NAT. So even if you make some tests, you can't have guaranteed that you will have connection with your API until you try.

As suggested by Rodja, prior to 4.0 there isn't a direct way to center the text with the drawable. And indeed setting a padding_left value does move the drawable away from the border. Therefore my suggestion is that on runtime you calculate exactly how many pixels from the left border your drawable needs to be and then pass it using setPadding Your calculation may be something like
int paddingLeft = (button.getWidth() - drawableWidth - textWidth) / 2;
The width of your drawable's is fixed and you can look it up and you can also calculate or guess the text width.
Finally, you would need to multiple the padding value by the screen density, which you can do using DisplayMetrics
Depending on situation where you need this, maybe you can use anonymous functions like this:
$greet = function($name)
{
echo('Hello ' . $name);
};
$greet('World');
...then you can set new function to the given variable any time
You must put the updatepanel id in the first argument if the control causing the script is inside the updatepanel else use the keyword 'this' instead of update panel here is the code

Vertical-align is one of the most misused css styles. It doesn't work how you might expect on elements that are not td's or css "display: table-cell".
This is a very good post on the matter. http://phrogz.net/CSS/vertical-align/index.html
The most common methods to acheive what you're looking for are:
Another approach would be to have an array of objects, with each individual object holding the properties of a column. This slightly changes the structure of "myMappings", but makes it easy to work with:
var myMappings = [
{ title: "Name", width: "10%" },
{ title: "Phone", width: "10%" },
{ title: "Address", width: "50%" },
{ title: "Zip", width: "10%" },
{ title: "Comments", width: "20%" }
];
Then you could easily iterate through all your "columns" with a for loop:
for (var i = 0; i < myMappings.length; i += 1) {
// myMappings[i].title ...
// myMappings[i].width ...
}
A lot of these answers are simplistic, and if someone is beginning WPF, they may not know all of the "ins-and-outs", as it is more complicated than just telling someone "Use .ShowDialog()
!". But that is the method (not .Show()
) that you want to use in order to block use of the underlying window and to keep the code from continuing until the modal window is closed.
First, you need 2 WPF windows. (One will be calling the other.)
From the first window, let's say that was called MainWindow.xaml, in its code-behind will be:
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
}
Then add your button to your XAML:
<Button Name="btnOpenModal" Click="btnOpenModal_Click" Content="Open Modal" />
And right-click the Click
routine, select "Go to definition". It will create it for you in MainWindow.xaml.cs:
private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
}
Within that function, you have to specify the other page using its page class. Say you named that other page "ModalWindow", so that becomes its page class and is how you would instantiate (call) it:
private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
ModalWindow modalWindow = new ModalWindow();
modalWindow.ShowDialog();
}
Say you have a value you need set on your modal dialog. Create a textbox and a button in the ModalWindow
XAML:
<StackPanel Orientation="Horizontal">
<TextBox Name="txtSomeBox" />
<Button Name="btnSaveData" Click="btnSaveData_Click" Content="Save" />
</StackPanel>
Then create an event handler (another Click
event) again and use it to save the textbox value to a public static variable on ModalWindow
and call this.Close()
.
public partial class ModalWindow : Window
{
public static string myValue = String.Empty;
public ModalWindow()
{
InitializeComponent();
}
private void btnSaveData_Click(object sender, RoutedEventArgs e)
{
myValue = txtSomeBox.Text;
this.Close();
}
}
Then, after your .ShowDialog()
statement, you can grab that value and use it:
private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
ModalWindow modalWindow = new ModalWindow();
modalWindow.ShowDialog();
string valueFromModalTextBox = ModalWindow.myValue;
}
If your data is already in your database you can do:
INSERT INTO MyTable(ID, Name)
SELECT ID, NAME FROM OtherTable
If you need to hard code the data then SQL 2008 and later versions let you do the following...
INSERT INTO MyTable (Name, ID)
VALUES ('First',1),
('Second',2),
('Third',3),
('Fourth',4),
('Fifth',5)
id
overviewAn Android id
is an integer commonly used to identify views; this id
can be assigned via XML (when possible) and via code (programmatically.) The id
is most useful for getting references for XML-defined View
s generated by an Inflater
(such as by using setContentView
.)
id
via XML
android:id="@+id/
somename"
to your view.android:id
will be assigned a unique int
for use in code.android:id
's int

somename" (effectively a constant.)int
can change from build to build so never copy an id from gen/

, just use "R.id.

.LinearLayout
with android:id="@+id/placeholder"
.ViewGroup
with View
s.id
s that are convenient to each view.Query these child views using placeholder.findViewById(convenientInt);
API 17 introduced View.generateViewId()
which allows you to generate a unique ID.
If you choose to keep references to your views around, be sure to instantiate them with getApplicationContext()
and be sure to set each reference to null in onDestroy
. Apparently leaking the Activity
(hanging onto it after is is destroyed) is wasteful.. :)
android:id
for use in codeAPI 17 introduced View.generateViewId()
which generates a unique ID. (Thanks to take-chances-make-changes for pointing this out.)*
If your ViewGroup
cannot be defined via XML (or you don't want it to be) you can reserve the id via XML to ensure it remains unique:
Here, values/ids.xml defines a custom id
:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<item name="reservedNamedId" type="id"/>
</resources>
Then once the ViewGroup or View has been created, you can attach the custom id
myViewGroup.setId(R.id.reservedNamedId);
id
exampleFor clarity by way of obfuscating example, lets examine what happens when there is an id
conflict behind the scenes.
layout/mylayout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:id="@+id/placeholder"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
</LinearLayout>
To simulate a conflict, lets say our latest build assigned R.id.placeholder
(@+id/placeholder
) an int
value of 12
..
Next, MyActivity.java defines some adds views programmatically (via code):
int placeholderId = R.id.placeholder; // placeholderId==12
// returns *placeholder* which has id==12:
ViewGroup placeholder = (ViewGroup)this.findViewById(placeholderId);
for (int i=0; i<20; i++){
TextView tv = new TextView(this.getApplicationContext());
// One new TextView will also be assigned an id==12:
tv.setId(i);
placeholder.addView(tv);
}
So placeholder
and one of our new TextView
s both have an id
of 12! But this isn't really a problem if we query placeholder's child views:
// Will return a generated TextView:
placeholder.findViewById(12);
// Whereas this will return the ViewGroup *placeholder*;
// as long as its R.id remains 12:
Activity.this.findViewById(12);
*Not so bad
I'm not aware of anything built-in. It's pretty simple to implement:
class assertMethodIsCalled(object):
def __init__(self, obj, method):
self.obj = obj
self.method = method
def called(self, *args, **kwargs):
self.method_called = True
self.orig_method(*args, **kwargs)

self.orig_method = getattr(self.obj, self.method)
setattr(self.obj, self.method, self.called)
self.method_called = False
def __exit__(self, exc_type, exc_value, traceback):
assert getattr(self.obj, self.method) == self.called,
"method %s was modified during assertMethodIsCalled" % self.method
setattr(self.obj, self.method, self.orig_method)
# If an exception was thrown within the block, we've already failed.
if traceback is None:
assert self.method_called,
"method %s of %s was not called" % (self.method, self.obj)
class test(object):
def a(self):
print "test"
def b(self):
self.a()
obj = test()
with assertMethodIsCalled(obj, "a"):
obj.b()
This requires that the object itself won't modify self.b, which is almost always true.
It seems that I found a solution to my problem. Very good explanations are given here and here. Here is my example:
pulic class MyActivity extends FragmentActivity{
private ViewPager pager;
private TitlePageIndicator indicator;
private TabsAdapter adapter;
private Bundle savedInstanceState;
@Override
public void onCreate(Bundle savedInstanceState) {
....
this.savedInstanceState = savedInstanceState;
pager = (ViewPager) findViewById(R.id.pager);;
indicator = (TitlePageIndicator) findViewById(R.id.indicator);
adapter = new TabsAdapter(getSupportFragmentManager(), false);
if (savedInstanceState == null){
adapter.addFragment(new FirstFragment());
adapter.addFragment(new SecondFragment());
}else{
Integer count = savedInstanceState.getInt("tabsCount");
String[] titles = savedInstanceState.getStringArray("titles");
for (int i = 0; i < count; i++){
adapter.addFragment(getFragment(i), titles[i]);
}
}
indicator.notifyDataSetChanged();
adapter.notifyDataSetChanged();
// push first task
FirstTask firstTask = new FirstTask(MyActivity.this);
// set first fragment as listener
firstTask.setTaskListener((TaskListener) getFragment(0));
firstTask.execute();
}
private Fragment getFragment(int position){
return savedInstanceState == null ? adapter.getItem(position) : getSupportFragmentManager().findFragmentByTag(getFragmentTag(position));
}
private String getFragmentTag(int position) {
return "android:switcher:" + R.id.pager + ":" + position;
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt("tabsCount", adapter.getCount());
outState.putStringArray("titles", adapter.getTitles().toArray(new String[0]));
}
indicator.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
Fragment currentFragment = adapter.getItem(position);
((Taskable) currentFragment).executeTask();
}
@Override
public void onPageScrolled(int i, float v, int i1) {}
@Override
public void onPageScrollStateChanged(int i) {}
});
The main idea in this code is that, while running your application normally, you create new fragments and pass them to the adapter. When you are resuming your application fragment manager already has this fragment's instance and you need to get it from fragment manager and pass it to the adapter.
UPDATE
Also, it is a good practice when using fragments to check isAdded before getActivity() is called. This helps avoid a null pointer exception when the fragment is detached from the activity. For example, an activity could contain a fragment that pushes an async task. When the task is finished, the onTaskComplete listener is called.
@Override
public void onTaskComplete(List<Feed> result) {
progress.setVisibility(View.GONE);
progress.setIndeterminate(false);
list.setVisibility(View.VISIBLE);
if (isAdded()) {
adapter = new FeedAdapter(getActivity(), R.layout.feed_item, result);
list.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
}
If we open the fragment, push a task, and then quickly press back to return to a previous activity, when the task is finished, it will try to access the activity in onPostExecute() by calling the getActivity() method. If the activity is already detached and this check is not there:
if (isAdded())
then the application crashes.
You can filter out rows that contain a NULL value in a specific column:
SELECT col1, col2, ..., coln
FROM yourtable
WHERE somecolumn IS NOT NULL
If you want to filter out rows that contain a null in any column then try this:
SELECT col1, col2, ..., coln
FROM yourtable
WHERE col1 IS NOT NULL
AND col2 IS NOT NULL
-- ...
AND coln IS NOT NULL
Update: Based on your comments, perhaps you want this?
SELECT * FROM
(
SELECT col1 AS col FROM yourtable
UNION
SELECT col2 AS col FROM yourtable
UNION
-- ...
UNION
SELECT coln AS col FROM yourtable
) T1
WHERE col IS NOT NULL
And I agre with Martin that if you need to do this then you should probably change your database design.
If Android Studio directly opening your project instead of setup window, then just close the windows of all projects. Now you will able to see the startup window. If SDK is missing then it will provide option to download SDK and other required tools.
It works for me.
Let me show you another way that works 100%. I will also add some padding for the example.
<div class = "container">
<div class = "flex-pad-x">
<div class = "flex-pad-y">
<div class = "flex-pad-y">
<div class = "flex-grow-y">
Content Centered
</div>
</div>
</div>
</div>
</div>
.container {
position: fixed;
top: 0px;
left: 0px;
bottom: 0px;
right: 0px;
width: 100%;
height: 100%;
}
.flex-pad-x {
padding: 0px 20px;
height: 100%;
display: flex;
}
.flex-pad-y {
padding: 20px 0px;
width: 100%;
display: flex;
flex-direction: column;
}
.flex-grow-y {
flex-grow: 1;
display: flex;
justify-content: center;
align-items: center;
flex-direction: column;
}
As you can see we can achieve this with a few wrappers for control while utilising the flex-grow & flex-direction attribute.
1: When the parent "flex-direction" is a "row", its child "flex-grow" works horizontally. 2: When the parent "flex-direction" is "columns", its child "flex-grow" works vertically.
Hope this helps

If your are using android studio go to file >> project structure on the left pane press on SDK location . you will find the path where your sdk is located
So I added curl AFTER my docker container was running.
(This was for debugging the container...I did not need a permanent addition)
I ran my image
docker run -d -p 8899:8080 my-image:latest
(the above makes my "app" available on my machine on port 8899) (not important to this question)
Then I listed and created terminal into the running container.
docker ps
docker exec -it my-container-id-here /bin/sh
If the exec
command above does not work, check this SOF article:
Error: Cannot Start Container: stat /bin/sh: no such file or directory"
then I ran:
apk
just to prove it existed in the running container, then i ran:
apk add curl
and got the below:
apk add curl
fetch http://dl-cdn.alpinelinux.org/alpine/v3.8/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.8/community/x86_64/APKINDEX.tar.gz

then i ran curl:
/ # curl
curl: try 'curl --help' or 'curl --manual' for more information
/ #
Note, to get "out" of the drilled-in-terminal-window, I had to open a new terminal window and stop the running container:
docker ps
docker stop my-container-id-here
APPEND:
If you don't have "apk" (which depends on which base image you are using), then try to use "another" installer. From other answers here, you can try:
apt-get -qq update
apt-get -qq -y install curl
none of that needed.... just go to:
now and load your csv file as-is. extra columns and all. it will slice and dice and use just the log & lat columns and plot it for you on google maps.
Use smaller h
// 24 hrs
H:i
// output 14:20
// 12 hrs
h:i
// output 2:20
Hit the Esc key to enter "Normal mode". Then you can type :
to enter "Command-line mode". A colon (:
) will appear at the bottom of the screen and you can type in one of the following commands. To execute a command, press the Enter key.
:q
to quit (short for :quit
):q!
to quit without saving (short for :quit!
):wq
to write and quit:wq!
to write and quit even if file has only read permission (if file does not have write permission: force write):x
to write and quit (similar to :wq
, but only write if there are changes):exit
to write and exit (same as :x
):qa
to quit all (short for :quitall
):cq
to quit without saving and make Vim return non-zero error (i.e. exit with error)You can also exit Vim directly from "Normal mode" by typing ZZ
to save and quit (same as :x
) or ZQ
to just quit (same as :q!
). (Note that case is important here. ZZ
and zz
do not mean the same thing.)
Vim has extensive help - that you can access with the :help
command - where you can find answers to all your questions and a tutorial for beginners.

I solved this question using Ajax. What I do is make an ajax call to a PHP page where the value that passes will be saved in session.
The example that I am going to show you, what I do is that when you change the value of the number of items to show in a datatable, that value is saved in session.
$('#table-campus').on( 'length.dt', function ( e, settings, len ) {
$.ajax ({
data: {"numElems": len},
url: '../../Utiles/GuardarNumElems.php',
type: 'post'
});
});
And the GuardarNumElems.php is as following:
<?php
session_start();
if(isset ($_POST['numElems'] )){
$numElems = $_POST['numElems'];
$_SESSION['elems_table'] = $numElems;
}else{
$_SESSION['elems_table'] = 25;
}
?>
I didn't see the C# anwer to this question here. The trick is to set the BrowserExecutableLocation property on a FirefoxOptions instance, and pass that into the driver constructor:
var opt = new FirefoxOptions
{
BrowserExecutableLocation = @"c:\program files\mozilla firefox\firefox.exe"
};
var driver = new FirefoxDriver(opt);
Do you want it to match "(b)"? Do as Zitrax and Paolo have suggested. Do you want it to match "b"? Do
>>> x = "a (b) c (d) e"
>>> re.search(r"\((.*?)\)", x).group(1)
'b'
Here's what I use on my site:
var objDiv = document.getElementById("your_div");
objDiv.scrollTop = objDiv.scrollHeight;
Suppose
a = ['a', 'b', 'c', 3, 4, 'd', 6, 7, 8]
and the list of indexes is stored in
b= [0, 1, 2, 4, 6, 7, 8]
then a simple one-line solution will be
c = [a[i] for i in b]
You shouldn't edit it, you should completely scrap it.
Any attempt to make execution stop for a certain amount of time will lock up the browser and switch it to a Not Responding state. The only thing you can do is use setTimeout
correctly.
In general, the way to deal with circular dependencies is to use setter injection.
I tried the setter injection code that you posted, and it worked for me. I would imagine the reason you are getting the exception is because Bean1 and Bean2 are in the com.myapp.beans package, and you don't have component scanning enabled for that package.
You'd need to add the following to your spring configuration:
<context:component-scan base-package="com.bullethq.accounts.web"/>
or move the beans to a package which is being automatically scanned by Spring.
You can do:
setContentPane(new JLabel(new ImageIcon("resources/taverna.jpg")));
At first line of the Jframe class constructor, that works fine for me
Template:
<input ng-click="check(profileForm.$valid)" name="submit"
id="submit" value="Save" class="submit" type="submit">
Controller:
$scope.check = function(value) {
if (value) {
updateMyProfile();
}
}
** Update ** A scalars converter has been added to retrofit that allows for a String
response with less ceremony than my original answer below.
Example interface --
public interface GitHubService {
@GET("/users/{user}")
Call<String> listRepos(@Path("user") String user);
}
Add the ScalarsConverterFactory
to your retrofit builder. Note: If using ScalarsConverterFactory
and another factory, add the scalars factory first.
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(ScalarsConverterFactory.create())
// add other factories here, if needed.
.build();
You will also need to include the scalars converter in your gradle file --
implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'
--- Original Answer (still works, just more code) ---
I agree with @CommonsWare that it seems a bit odd that you want to intercept the request to process the JSON yourself. Most of the time the POJO has all the data you need, so no need to mess around in JSONObject
land. I suspect your specific problem might be better solved using a custom gson TypeAdapter
or a retrofit Converter
if you need to manipulate the JSON. However, retrofit provides more the just JSON parsing via Gson. It also manages a lot of the other tedious tasks involved in REST requests. Just because you don't want to use one of the features, doesn't mean you have to throw the whole thing out. There are times you just want to get the raw stream, so here is how to do it -
First, if you are using Retrofit 2, you should start using the Call
API. Instead of sending an object to convert as the type parameter, use ResponseBody
from okhttp --
public interface GitHubService {
@GET("/users/{user}")
Call<ResponseBody> listRepos(@Path("user") String user);
}
then you can create and execute your call --
GitHubService service = retrofit.create(GitHubService.class);
Call<ResponseBody> result = service.listRepos(username);
result.enqueue(new Callback<ResponseBody>() {
@Override
public void onResponse(Response<ResponseBody> response) {
try {
System.out.println(response.body().string());
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void onFailure(Throwable t) {
e.printStackTrace();
}
});
Note The code above calls string()
on the response object, which reads the entire response into a String. If you are passing the body off to something that can ingest streams, you can call charStream()
instead. See the ResponseBody
docs.
That won't work if the string contains more than one match... try this:
echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo " $0) }'
or better (if the echo
isn't a placeholder for something else):
echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'
In your case you want to make a copy of the value before changing it:
echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'
Why not just put this in your css:
input --webkit-autocomplete {
color: inherit;
background: inherit;
border: inherit;
}
That should take care of your issue. Although it does raise a usability issue because now the user can't see that the form was autofilled in the way he/she is used to.
[edit] After posting this I saw that a similar answer was already given and that you commented on it that it didn't work. I don't quite see why because it did work when I tested it.
You can handle it using this :
catch((error) => {
this.setState({
typing_animation_button: false,
});
console.log(error);
if ('Timeout' || 'Network request failed') {
toast_show = true;
toast_type = 'error';
toast_text = 'Network failure';
}
this.setState({
disable_button: false,
});
});
I have the same problem on my virtual environment after upgrade python installation from 3.6 to 3.7 but only on vent globally pip work fine, to solve it I deactivate and delete my virtual environment after recreate again and now is fine, on venv:
deactivate
rm -rvf venv
and after recreate the virtual environment. I use mac OS 10.11, and python 3
you can use PHP's end()
$array = array('a' => 1,'b' => 2,'c' => 3);
$lastElement = end($array);
foreach($array as $k => $v) {
echo $v . '<br/>';
if($v == $lastElement) {
// 'you can do something here as this condition states it just entered last element of an array';
}
}
Update1
as pointed out by @Mijoja the above could will have problem if you have same value multiple times in array. below is the fix for it.
$array = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 2);
//point to end of the array
end($array);
//fetch key of the last element of the array.
$lastElementKey = key($array);
//iterate the array
foreach($array as $k => $v) {
if($k == $lastElementKey) {
//during array iteration this condition states the last element.
}
}
Update2
I found solution by @onteria_ to be better then what i have answered since it does not modify arrays internal pointer, i am updating the answer to match his answer.
$array = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 2);
// Get array keys
$arrayKeys = array_keys($array);
// Fetch last array key
$lastArrayKey = array_pop($arrayKeys);
//iterate array
foreach($array as $k => $v) {
if($k == $lastArrayKey) {
//during array iteration this condition states the last element.
}
}
Thank you @onteria_
Update3
As pointed by @CGundlach PHP 7.3 introduced array_key_last
which seems much better option if you are using PHP >= 7.3
$array = array('a' => 1,'b' => 2,'c' => 3);
$lastKey = array_key_last($array);
foreach($array as $k => $v) {
echo $v . '<br/>';
if($k == $lastKey) {
// 'you can do something here as this condition states it just entered last element of an array';
}
}
This Should work Making it Round to 2 Point
int a=53214
parseFloat(Math.round(a* 100) / 100).toFixed(2);
I think that Aidan's answer is by far the best.
$('#yourgrid').jqGrid("editCell", 0, 0, false);
This commits any current edits, giving you access to the real value. I prefer it because:
- You don't have to hard-code any cell references in.
- It is particularly well suited to using getRowData() to get the entire grid, as it doesn't care which cell you've just been editing.
- You're not trying to parse some markup generated by jqGrid which may change in future.
- If the user is saving, then ending the edit session is likely the behaviour they would want anyway.
I would recommend using Offset
assuming that the Headers are in Row 1. See this example
Option Explicit
Sub Sample()
Dim rRange As Range, filRange As Range, Rng as Range
'Remove any filters
ActiveSheet.AutoFilterMode = False
'~~> Set your range
Set rRange = Sheets("Sheet1").Range("A1:E10")
With rRange
'~~> Set your criteria and filter
.AutoFilter Field:=1, Criteria1:="=1"
'~~> Filter, offset(to exclude headers)
Set filRange = .Offset(1, 0).SpecialCells(xlCellTypeVisible).EntireRow
Debug.Print filRange.Address
For Each Rng In filRange
'~~> Your Code
Next
End With
'Remove any filters
ActiveSheet.AutoFilterMode = False
End Sub
use:
$scope.users.length;
Instead of:
$scope.users.lenght;
And next time "spell-check" your code.
Here are some differences:
You can call app.render
on root level and res.render
only inside a route/middleware.
app.render
always returns the html
in the callback function, whereas res.render
does so only when you've specified the callback function as your third parameter. If you call res.render
without the third parameter/callback function the rendered html is sent to the client with a status code of 200
.
Take a look at the following examples.
app.render
app.render('index', {title: 'res vs app render'}, function(err, html) {
console.log(html)
});
// logs the following string (from default index.jade)
<!DOCTYPE html><html><head><title>res vs app render</title><link rel="stylesheet" href="/stylesheets/style.css"></head><body><h1>res vs app render</h1><p>Welcome to res vs app render</p></body></html>
res.render
without third parameter
app.get('/render', function(req, res) {
res.render('index', {title: 'res vs app render'})
})
// also renders index.jade but sends it to the client
// with status 200 and content-type text/html on GET /render
res.render
with third parameter
app.get('/render', function(req, res) {
res.render('index', {title: 'res vs app render'}, function(err, html) {
console.log(html);
res.send('done');
})
})
// logs the same as app.render and sends "done" to the client instead
// of the content of index.jade
res.render
uses app.render
internally to render template files.
You can use the render
functions to create html emails. Depending on your structure of your app, you might not always have acces to the app
object.
For example inside an external route:
app.js
var routes = require('routes');
app.get('/mail', function(req, res) {
// app object is available -> app.render
})
app.get('/sendmail', routes.sendmail);
routes.js
exports.sendmail = function(req, res) {
// can't use app.render -> therefore res.render
}
You can do this in your view without doing anything special in your action by using Html.ValidationSummary() to show all error messages, or Html.ValidationMessageFor() to show a message for a specific property of the model.
If you still need to see the errors from within your action or controller, see the ModelState.Errors property
Just add the following rules to the parent element:
display: flex;
justify-content: center; /* align horizontal */
align-items: center; /* align vertical */
Here's a sample demo (Resize window to see the image align)
Browser support for Flexbox nowadays is quite good.
For cross-browser compatibility for display: flex
and align-items
, you can add the older flexbox syntax as well:
display: -webkit-box;
display: -webkit-flex;
display: -moz-box;
display: -ms-flexbox;
display: flex;
-webkit-flex-align: center;
-ms-flex-align: center;
-webkit-align-items: center;
align-items: center;
I moved ico file to root folder and link it. It worked for me. Also, in chrome, I have to wait 30 mins to get cache cleared and new changes to take affect.
%S
seems to conform to The Single Unix Specification v2 and is also part of the current (2008) POSIX specification.
Equivalent C99 conforming format specifiers would be %s
and %ls
.
This code worked for me
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<UserDetail>()
.HasRequired(d => d.User)
.WithOptional(u => u.UserDetail)
.WillCascadeOnDelete(true);
}
The migration code was:
public override void Up()
{
AddForeignKey("UserDetail", "UserId", "User", "UserId", cascadeDelete: true);
}
And it worked fine. When I first used
modelBuilder.Entity<User>()
.HasOptional(a => a.UserDetail)
.WithOptionalDependent()
.WillCascadeOnDelete(true);
The migration code was:
AddForeignKey("User", "UserDetail_UserId", "UserDetail", "UserId", cascadeDelete: true);
but it does not match any of the two overloads available (in EntityFramework 6)
The following is the one that I'm using to generate a vertical gradient from completely opaque (top) to 20% in transparency (bottom) for the same color:
background: linear-gradient(to bottom, rgba(0, 64, 122, 1) 0%,rgba(0, 64, 122, 0.8) 100%); /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
background: -o-linear-gradient(top, rgba(0, 64, 122, 1) 0%, rgba(0, 64, 122, 0.8) 100%); /* Opera 11.10+ */

-ms-filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#00407a', endColorstr='#cc00407a',GradientType=0 ); /* IE8 */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#00407a', endColorstr='#cc00407a',GradientType=0 ); /* IE 5.5 - 9 */
I had the same issue. It's solved by adding following lines in .bashrc
:
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"

You can use strstr to do this.
echo strstr($str, 'www/audio');
You could use assign
, but using assign
(or get
) is often a symptom of a programming structure that is not very R like. Typically, lists or matrices allow cleaner solutions.
with a list:
A <- lapply (1 : 10, function (x) d + rnorm (3))
with a matrix:
A <- matrix (rep (d, each = 10) + rnorm (30), nrow = 10)
You don't have to do this locally either. You can do it through a remote repository, for example:
svn export http://<repo>/process/test.txt /path/to/code/
You can use an optional parameter of JSON.stringify()
JSON.stringify(value[, replacer [, space]])
Parameters
- value The value to convert to a JSON string.
- replacer If a function, transforms values and properties encountered while stringifying; if an array, specifies the set of properties included in objects in the final string. A detailed description of the replacer function is provided in the javaScript guide article Using native JSON.
- space Causes the resulting string to be pretty-printed.
For example:
JSON.stringify({a:1,b:2,c:{d:3, e:4}},null," ")
will give you following result:
"{
"a": 1,
"b": 2,
"c": {
"d": 3,
"e": 4
}
}"
No doubt that you are correct Florin. I was working on this project, and found that this piece of code:
product = await response.Content.ReadAsAsync<Product>();
Could be replaced with:
response.Content = new StringContent(string product);
You should amend creation of the gesture recogniser to accept parameter (add colon ':')
UITapGestureRecognizer *letterTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(highlightLetter:)];
And in your method highlightLetter: you can access the view attached to recogniser:
-(IBAction) highlightLetter:(UITapGestureRecognizer*)recognizer
{
UIView *view = [recognizer view];
}
For this task, I recommend using Android Studio IDE and choose the automatic installation program, and not the compressed file.
don't recommend Beta or Canary
channel which is the unstable version and they are not automatic installation, instead a zip file is provided in that case.
Warning: Among different version of Android Studio, the steps may be different. But hopefully you get the idea, as I try to be clear on my intentions.
Extra info: If you want, check for Android Studio updates @ Android Tools Project Site - Recent Builds. This web page seems to be more accurate than other Android pages about tool updates.
