Your javascript is executed before the HTML is generated, so it doesn't "see" the ungenerated INPUT elements. For jQuery, you would either stick the Javascript at the end of the HTML or wrap it like this:
<script type="text/javascript"> $(function() { //jQuery trick to say after all the HTML is parsed. $("input[type=radio]").click(function() { var total = 0; $("input[type=radio]:checked").each(function() { total += parseFloat($(this).val()); }); $("#totalSum").val(total); }); }); </script>
EDIT: This code works for me
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body> <strong>Choose a base package:</strong> <input id="item_0" type="radio" name="pkg" value="1942" />Base Package 1 - $1942 <input id="item_1" type="radio" name="pkg" value="2313" />Base Package 2 - $2313 <input id="item_2" type="radio" name="pkg" value="2829" />Base Package 3 - $2829 <strong>Choose an add on:</strong> <input id="item_10" type="radio" name="ext" value="0" />No add-on - +$0 <input id="item_12" type="radio" name="ext" value="2146" />Add-on 1 - (+$2146) <input id="item_13" type="radio" name="ext" value="2455" />Add-on 2 - (+$2455) <input id="item_14" type="radio" name="ext" value="2764" />Add-on 3 - (+$2764) <input id="item_15" type="radio" name="ext" value="3073" />Add-on 4 - (+$3073) <input id="item_16" type="radio" name="ext" value="3382" />Add-on 5 - (+$3382) <input id="item_17" type="radio" name="ext" value="3691" />Add-on 6 - (+$3691) <strong>Your total is:</strong> <input id="totalSum" type="text" name="totalSum" readonly="readonly" size="5" value="" /> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script> <script type="text/javascript"> $("input[type=radio]").click(function() { var total = 0; $("input[type=radio]:checked").each(function() { total += parseFloat($(this).val()); }); $("#totalSum").val(total); }); </script> </body> </html>

You can change the number format of the column to this custom format:
0;-0;;@
which will hide all 0 values.
To do this, select the column, right-click > Format Cells > Custom.
must means: The clause (query) must appear in matching documents. These clauses must match, like logical AND.
should means: At least one of these clauses must match, like logical OR.
Basically they are used like logical operators AND and OR. See this.
Now in a bool query:
must means: Clauses that must match for the document to be included.
should means: If these clauses match, they increase the _score
; otherwise, they have no effect. They are simply used to refine the relevance score for each document.
Yes you can use multiple filters inside must

That should help
df.groupby(['NFF', 'ABUSE']).size().unstack().plot(kind='bar', stacked=True)
You don't need an IIF() at all here. The comparisons return true or false anyway.
Also, since this row visibility is on a group row, make sure you use the same aggregate function on the fields as you use in the fields in the row. So if your group row shows sums, then you'd put this in the Hidden property.
=Sum(Fields!OpeningStock.Value) = 0 And
Sum(Fields!GrossDispatched.Value) = 0 And
Sum(Fields!TransferOutToMW.Value) = 0 And
Sum(Fields!TransferOutToDW.Value) = 0 And
Sum(Fields!TransferOutToOW.Value) = 0 And
Sum(Fields!NetDispatched.Value) = 0 And
Sum(Fields!QtySold.Value) = 0 And
Sum(Fields!StockAdjustment.Value) = 0 And
Sum(Fields!ClosingStock.Value) = 0
But with the above version, if one record has value 1 and one has value -1 and all others are zero then sum is also zero and the row could be hidden. If that's not what you want you could write a more complex expression:
=Sum(
IIF(
Fields!OpeningStock.Value=0 AND
Fields!GrossDispatched.Value=0 AND
Fields!TransferOutToMW.Value=0 AND
Fields!TransferOutToDW.Value=0 AND
Fields!TransferOutToOW.Value=0 AND
Fields!NetDispatched.Value=0 AND
Fields!QtySold.Value=0 AND
Fields!StockAdjustment.Value=0 AND
Fields!ClosingStock.Value=0,
0,
1
)
) = 0
This is essentially a fancy way of counting the number of rows in which any field is not zero. If every field is zero for every row in the group then the expression returns true and the row is hidden.
Since you want to pivot multiple columns of data, I would first suggest unpivoting the result
, score
and grade
columns so you don't have multiple columns but you will have multiple rows.
Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:
select ratio, col, value
from GRAND_TOTALS
cross apply
(
select 'result', cast(result as varchar(10)) union all
select 'score', cast(score as varchar(10)) union all
select 'grade', grade
) c(col, value)
See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:
select ratio = col,
[current ratio], [gearing ratio], [performance ratio], total
from
(
select ratio, col, value
from GRAND_TOTALS
cross apply
(
select 'result', cast(result as varchar(10)) union all
select 'score', cast(score as varchar(10)) union all
select 'grade', grade
) c(col, value)
) d
pivot
(
max(value)
for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;
See SQL Fiddle with Demo. This will give you the result:
| RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO | TOTAL |
|--------|---------------|---------------|-------------------|-----------|
| grade | Good | Good | Satisfactory | Good |
| result | 1.29400 | 0.33840 | 0.04270 | (null) |
| score | 60.00000 | 70.00000 | 50.00000 | 180.00000 |
String.prototype.match
returns an array, we can then check the length,
I find this method to be most descriptive
var str = 'one two three four five';
str.match(/\w+/g).length;
Setting command timeout to 2 minutes.
scGetruntotals.CommandTimeout = 120;
but you can optimize your stored Procedures to decrease that time! like
Strongly simplified version of max
:
def max(items, key=lambda x: x):
current = item[0]
for item in items:
if key(item) > key(current):
current = item
return current
Regarding lambda:
>>> ident = lambda x: x
>>> ident(3)
3
>>> ident(5)
5
>>> times_two = lambda x: 2*x
>>> times_two(2)
4
You could use the ROLLUP operator
SELECT CASE
WHEN (GROUPING([Type]) = 1) THEN 'Total'
ELSE [Type] END AS [TYPE]
,SUM([Total Sales]) as Total_Sales
From Before
GROUP BY
[Type] WITH ROLLUP
Try cast result to numeric
CAST(sum(cast(datediff(second, IEC.CREATE_DATE, IEC.STATUS_DATE) as float) / 60)
AS numeric(10,2)) TotalSentMinutes
Input
1
2
3
Output
1.00
2.00
3.00

The good news is a transaction in SQL Server can span multiple batches (each exec
is treated as a separate batch.)
You can wrap your EXEC
statements in a BEGIN TRANSACTION
and COMMIT
but you'll need to go a step further and rollback if any errors occur.
Ideally you'd want something like this:
BEGIN TRY
BEGIN TRANSACTION
exec( @sqlHeader)
exec(@sqlTotals)
exec(@sqlLine)
COMMIT
END TRY
BEGIN CATCH
IF @@TRANCOUNT > 0
ROLLBACK
END CATCH
The BEGIN TRANSACTION
and COMMIT
I believe you are already familiar with. The BEGIN TRY
and BEGIN CATCH
blocks are basically there to catch and handle any errors that occur. If any of your EXEC
statements raise an error, the code execution will jump to the CATCH
block.
Your existing SQL building code should be outside the transaction (above) as you always want to keep your transactions as short as possible.
I think you're making this a bit more complicated than it needs to be.
SELECT
ProductID,
SUM(IF(PaymentMethod = 'Cash', Amount, 0)) AS 'Cash',
-- snip
SUM(Amount) AS Total

WHERE

GROUP BY

Let's fully answer the original question while reusing code that was already written (i.e., Underscore). You can do much more with Underscore if you combine its >100 functions. The following solution demonstrates this.
Step 1: group the objects in the array by an arbitrary combination of properties. This uses the fact that _.groupBy
accepts a function that returns the group of an object. It also uses _.chain
, _.pick
, _.values
, _.join
and _.value
. Note that _.value
is not strictly needed here, because chained values will automatically unwrap when used as a property name. I'm including it to safeguard against confusion in case somebody tries to write similar code in a context where automatic unwrapping does not take place.
// Given an object, return a string naming the group it belongs to.
function category(obj) {
return _.chain(obj).pick(propertyNames).values().join(' ').value();
}
// Perform the grouping.
const intermediate = _.groupBy(arrayOfObjects, category);
Given the arrayOfObjects
in the original question and setting propertyNames
to ['Phase', 'Step']
, intermediate
will get the following value:
{
"Phase 1 Step 1": [
{ Phase: "Phase 1", Step: "Step 1", Task: "Task 1", Value: "5" },
{ Phase: "Phase 1", Step: "Step 1", Task: "Task 2", Value: "10" }
],
"Phase 1 Step 2": [
{ Phase: "Phase 1", Step: "Step 2", Task: "Task 1", Value: "15" },
{ Phase: "Phase 1", Step: "Step 2", Task: "Task 2", Value: "20" }
],
"Phase 2 Step 1": [
{ Phase: "Phase 2", Step: "Step 1", Task: "Task 1", Value: "25" },
{ Phase: "Phase 2", Step: "Step 1", Task: "Task 2", Value: "30" }
],
"Phase 2 Step 2": [
{ Phase: "Phase 2", Step: "Step 2", Task: "Task 1", Value: "35" },
{ Phase: "Phase 2", Step: "Step 2", Task: "Task 2", Value: "40" }
]
}
Step 2: reduce each group to a single flat object and return the results in an array. Besides the functions we have seen before, the following code uses _.pluck
, _.first
, _.pick
, _.extend
, _.reduce
and _.map
. _.first
is guaranteed to return an object in this case, because _.groupBy
does not produce empty groups. _.value
is necessary in this case.
// Sum two numbers, even if they are contained in strings.
const addNumeric = (a, b) => +a + +b;
// Given a `group` of objects, return a flat object with their common
// properties and the sum of the property with name `aggregateProperty`.
function summarize(group) {
const valuesToSum = _.pluck(group, aggregateProperty);
return _.chain(group).first().pick(propertyNames).extend({
[aggregateProperty]: _.reduce(valuesToSum, addNumeric)
}).value();
}
// Get an array with all the computed aggregates.
const result = _.map(intermediate, summarize);
Given the intermediate
that we obtained before and setting aggregateProperty
to Value
, we get the result
that the asker desired:
[
{ Phase: "Phase 1", Step: "Step 1", Value: 15 },
{ Phase: "Phase 1", Step: "Step 2", Value: 35 },
{ Phase: "Phase 2", Step: "Step 1", Value: 55 },
{ Phase: "Phase 2", Step: "Step 2", Value: 75 }
]
We can put this all together in a function that takes arrayOfObjects
, propertyNames
and aggregateProperty
as parameters. Note that arrayOfObjects
can actually also be a plain object with string keys, because _.groupBy
accepts either. For this reason, I have renamed arrayOfObjects
to collection
.
function aggregate(collection, propertyNames, aggregateProperty) {
function category(obj) {
return _.chain(obj).pick(propertyNames).values().join(' ');
}
const addNumeric = (a, b) => +a + +b;
function summarize(group) {
const valuesToSum = _.pluck(group, aggregateProperty);
return _.chain(group).first().pick(propertyNames).extend({
[aggregateProperty]: _.reduce(valuesToSum, addNumeric)
}).value();
}
return _.chain(collection).groupBy(category).map(summarize).value();
}
aggregate(arrayOfObjects, ['Phase', 'Step'], 'Value')
will now give us the same result
again.
We can take this a step further and enable the caller to compute any statistic over the values in each group. We can do this and also enable the caller to add arbitrary properties to the summary of each group. We can do all of this while making our code shorter. We replace the aggregateProperty
parameter by an iteratee
parameter and pass this straight to _.reduce
:
function aggregate(collection, propertyNames, iteratee) {
function category(obj) {
return _.chain(obj).pick(propertyNames).values().join(' ');
}
function summarize(group) {
return _.chain(group).first().pick(propertyNames)
.extend(_.reduce(group, iteratee)).value();
}
return _.chain(collection).groupBy(category).map(summarize).value();
}
In effect, we move some of the responsibility to the caller; she must provide an iteratee
that can be passed to _.reduce
, so that the call to _.reduce
will produce an object with the aggregate properties she wants to add. For example, we obtain the same result
as before with the following expression:
aggregate(arrayOfObjects, ['Phase', 'Step'], (memo, value) => ({
Value: +memo.Value + +value.Value
}));
For an example of a slightly more sophisticated iteratee
, suppose that we want to compute the maximum Value
of each group instead of the sum, and that we want to add a Tasks
property that lists all the values of Task
that occur in the group. Here's one way we can do this, using the last version of aggregate
above (and _.union
):
aggregate(arrayOfObjects, ['Phase', 'Step'], (memo, value) => ({
Value: Math.max(memo.Value, value.Value),
Tasks: _.union(memo.Tasks || [memo.Task], [value.Task])
}));
We obtain the following result:
[
{ Phase: "Phase 1", Step: "Step 1", Value: 10, Tasks: [ "Task 1", "Task 2" ] },
{ Phase: "Phase 1", Step: "Step 2", Value: 20, Tasks: [ "Task 1", "Task 2" ] },
{ Phase: "Phase 2", Step: "Step 1", Value: 30, Tasks: [ "Task 1", "Task 2" ] },
{ Phase: "Phase 2", Step: "Step 2", Value: 40, Tasks: [ "Task 1", "Task 2" ] }
]
Credit to @much2learn, who also posted an answer that can handle arbitrary reducing functions. I wrote a couple more SO answers that demonstrate how one can achieve sophisticated things by combining multiple Underscore functions:
var string = 123 (is string),
parseInt(parameter is string);
var string = '123';
var int= parseInt(string );
console.log(int); //Output will be 123.
Here is a short and sweet answer with an example.

To answer this point:
I want Sleep to be an async method so it can await other methods
you can maybe rewrite the Sleep
function like this:
private static async Task<int> Sleep(int ms)
{
Console.WriteLine("Sleeping for " + ms);
var task = Task.Run(() => Thread.Sleep(ms));
await task;
Console.WriteLine("Sleeping for " + ms + "END");
return ms;
}
static void Main(string[] args)
{
Console.WriteLine("Starting");
var task1 = Sleep(2000);
var task2 = Sleep(1000);
int totalSlept = task1.Result +task2.Result;
Console.WriteLine("Slept for " + totalSlept + " ms");
Console.ReadKey();
}
running this code will output :
Starting
Sleeping for 2000
Sleeping for 1000
*(one second later)*
Sleeping for 1000END
*(one second later)*
Sleeping for 2000END
Slept for 3000 ms
In JavaScript, most functions are both callable and instantiable: they have both a [[Call]] and [[Construct]] internal methods.
As callable objects, you can use parentheses to call them, optionally passing some arguments. As a result of the call, the function can return a value.
var player = makeGamePlayer("John Smith", 15, 3);
The code above calls function makeGamePlayer
and stores the returned value in the variable player
. In this case, you may want to define the function like this:
function makeGamePlayer(name, totalScore, gamesPlayed) {
// Define desired object
var obj = {
name: name,
totalScore: totalScore,
gamesPlayed: gamesPlayed
};
// Return it
return obj;
}
Additionally, when you call a function you are also passing an additional argument under the hood, which determines the value of this
inside the function. In the case above, since makeGamePlayer
is not called as a method, the this
value will be the global object in sloppy mode, or undefined in strict mode.
As constructors, you can use the new
operator to instantiate them. This operator uses the [[Construct]] internal method (only available in constructors), which does something like this:
.prototype
of the constructorthis
valuevar player = new GamePlayer("John Smith", 15, 3);
The code above creates an instance of GamePlayer
and stores the returned value in the variable player
. In this case, you may want to define the function like this:
function GamePlayer(name,totalScore,gamesPlayed) {
// `this` is the instance which is currently being created
this.name = name;
this.totalScore = totalScore;
this.gamesPlayed = gamesPlayed;
// No need to return, but you can use `return this;` if you want
}
By convention, constructor names begin with an uppercase letter.
The advantage of using constructors is that the instances inherit from GamePlayer.prototype
. Then, you can define properties there and make them available in all instances

You can have a different goroutine that detects syscall.SIGINT and syscall.SIGTERM signals and relay them to a channel using signal.Notify. You can send a hook to that goroutine using a channel and save it in a function slice. When the shutdown signal is detected on the channel, you can execute those functions in the slice. This can be used to clean up the resources, wait for running goroutines to finish, persist data, or print partial run totals.
I wrote a small and simple utility to add and run hooks at shutdown. Hope it can be of help.
https://github.com/ankit-arora/go-utils/blob/master/go-shutdown-hook/shutdown-hook.go
You can do this in a 'defer' fashion.
example for shutting down a server gracefully :
srv := &http.Server{}
go_shutdown_hook.ADD(func() {
log.Println("shutting down server")
srv.Shutdown(nil)
log.Println("shutting down server-done")
})
l, err := net.Listen("tcp", ":3090")
log.Println(srv.Serve(l))
go_shutdown_hook.Wait()
Necromancing:
It's relativiely simple to emulate a COUNT DISTINCT over PARTITION BY with MAX via DENSE_RANK:
;WITH baseTable AS
(
SELECT 'RM1' AS RM, 'ADR1' AS ADR
UNION ALL SELECT 'RM1' AS RM, 'ADR1' AS ADR
UNION ALL SELECT 'RM2' AS RM, 'ADR1' AS ADR
UNION ALL SELECT 'RM2' AS RM, 'ADR2' AS ADR
UNION ALL SELECT 'RM2' AS RM, 'ADR2' AS ADR
UNION ALL SELECT 'RM2' AS RM, 'ADR3' AS ADR
UNION ALL SELECT 'RM3' AS RM, 'ADR1' AS ADR
UNION ALL SELECT 'RM2' AS RM, 'ADR1' AS ADR
UNION ALL SELECT 'RM3' AS RM, 'ADR1' AS ADR
UNION ALL SELECT 'RM3' AS RM, 'ADR2' AS ADR
)
,CTE AS
(
SELECT RM, ADR, DENSE_RANK() OVER(PARTITION BY RM ORDER BY ADR) AS dr
FROM baseTable
)
SELECT
RM
,ADR
,COUNT(CTE.ADR) OVER (PARTITION BY CTE.RM ORDER BY ADR) AS cnt1
,COUNT(CTE.ADR) OVER (PARTITION BY CTE.RM) AS cnt2
-- Not supported
--,COUNT(DISTINCT CTE.ADR) OVER (PARTITION BY CTE.RM ORDER BY CTE.ADR) AS cntDist
,MAX(CTE.dr) OVER (PARTITION BY CTE.RM ORDER BY CTE.RM) AS cntDistEmu
FROM CTE
Note:
This assumes the fields in question are NON-nullable fields.
If there is one or more NULL-entries in the fields, you need to subtract 1.
UPDATE totals
SET total = total + 1
WHERE name = 'bill';
If you want to make sure the current value is indeed 203 (and not accidently increase it again) you can also add another condition:
UPDATE totals
SET total = total + 1
WHERE name = 'bill'
AND total = 203;
Did a quick google. Seems that to find the file size you do this,
long size = f.length();
The differences between the three methods you posted can be found here
getFreeSpace() and getTotalSpace() are pretty self explanatory, getUsableSpace() seems to be the space that the JVM can use, which in most cases will be the same as the amount of free space.
SELECT CONVERT(NVARCHAR(10), PaymentDate, 120) [Month], SUM(Amount) [TotalAmount]
FROM Payments
GROUP BY CONVERT(NVARCHAR(10), PaymentDate, 120)
ORDER BY [Month]
You could also try:
SELECT DATEPART(Year, PaymentDate) Year, DATEPART(Month, PaymentDate) Month, SUM(Amount) [TotalAmount]
FROM Payments
GROUP BY DATEPART(Year, PaymentDate), DATEPART(Month, PaymentDate)
ORDER BY Year, Month
I've noticed bizarre behavior with Eclipse version 4.2.1 delivering me this error:
String cannot be resolved to a variable
With this Java code:
if (true)
String my_variable = "somevalue";
System.out.println("foobar");
You would think this code is very straight forward, the conditional is true, we set my_variable to somevalue. And it should print foobar. Right?
Wrong, you get the above mentioned compile time error. Eclipse is trying to prevent you from making a mistake by assuming that both statements are within the if statement.
If you put braces around the conditional block like this:
if (true){
String my_variable = "somevalue"; }
System.out.println("foobar");
Then it compiles and runs fine. Apparently poorly bracketed conditionals are fair game for generating compile time errors now.
Cleaned up the code (commented out the logger mostly) to make it run in my Eclipse environment.

Created this little testcode:
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
public class ReadXLSXTest {
/**
* @param args
* @throws FileNotFoundException
*/
public static void main(String[] args) throws FileNotFoundException {
// TODO Auto-generated method stub
ReadXLSX test = new ReadXLSX(new FileInputStream(new File("./sample.xlsx")));
System.out.println(test.getSheetsName());
System.out.println(test.getNumberOfSheet());
}
}
All this ran like a charm, so my guess is you have an XLSX file that is 'corrupt' in one way or another. Try testing with other data.

xhr.file = file;
; the file object is not supposed to be attached this way.xhr.send(file)
doesn't send the file. You have to use the FormData
object to wrap the file into a multipart/form-data
post data object:
var formData = new FormData();
formData.append("thefile", file);
xhr.send(formData);
After that, the file can be access in $_FILES['thefile']
(if you are using PHP).
Remember, MDC and Mozilla Hack demos are your best friends.
EDIT: The (2) above was incorrect. It does send the file, but it would send it as raw post data. That means you would have to parse it yourself on the server (and it's often not possible, depend on server configuration). Read how to get raw post data in PHP here.
The problem is the length of the filenames. The first filename is only 7 chars long, so the tab occurs at char 8 (doing a tab after every 4 characters). However the next filenames are 8 chars long, so the next tab won't be until char 12. And if you had filenames longer than 11 chars, you'd run into the same problem again.
Try this:
DataTable dt = new DataTable();
int sum = 0;
foreach (DataRow dr in dt.Rows)
{
foreach (DataColumn dc in dt.Columns)
{
sum += (int)dr[dc];
}
}
Another way that is never talked about is Create a view in MSSQL with all the data you want to present. Then use LINQ to SQL or whatever to map it. In your controller return it to the view. Done.
In your for loop you need to multiply the units * price. That gives you the total for that particular item. Also in the for loop you should add that to a counter that keeps track of the grand total. Your code would look something like
float total;
total += theItem.getUnits() * theItem.getPrice();
total should be scoped so it's accessible from within main unless you want to pass it around between function calls. Then you can either just print out the total or create a method that prints it out for you.
Looks like MySQLdb doesn't actually provide a translation for that API call. The relevant C API call is mysql_fetch_fields
, and there is no MySQLdb translation for that
Here's a function I wrote which works similarly to the Unix time
command:
function time {
Param(
[Parameter(Mandatory=$true)]
[string]$command,
[switch]$quiet = $false
)
$start = Get-Date
try {
if ( -not $quiet ) {
iex $command | Write-Host
} else {
iex $command > $null
}
} finally {
$(Get-Date) - $start
}
}

That approach will be good if the date-time in question is in UTC, or represents local time in an area that has never observed daylight saving time. The DateTime difference routines do not take into account Daylight Saving Time, and consequently will regard midnight June 1 as being a multiple of 24 hours after midnight January 1. I'm unaware of anything in Windows that reports historical daylight-saving rules for the current locale, so I don't think there's any good way to correctly handle any time prior to the most recent daylight-saving rule change.
There is a lot of partial information on this page, but not a complete one. Here is what I do:
<DIV id='container'>
that I put all of my content inHere is an example:

background: -moz-linear-gradient(-45deg, #a9e4f7 0%, #0fb4e7 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, right bottom, color-stop(0%,#a9e4f7), color-stop(100%,#0fb4e7)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(-45deg, #a9e4f7 0%,#0fb4e7 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(-45deg, #a9e4f7 0%,#0fb4e7 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(-45deg, #a9e4f7 0%,#0fb4e7 100%); /* IE10+ */
background: linear-gradient(135deg, #a9e4f7 0%,#0fb4e7 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#a9e4f7', endColorstr='#0fb4e7',GradientType=1 ); /* IE6-9 fallback on horizontal gradient */
background-attachment: fixed;
}
body {
margin-top: 0px;
margin-bottom: 0px;
}
/* OPTIONAL: div to store content. Many of these attributes should be changed to suit your needs */
#container
{
width: 800px;
margin: auto;
background-color: white;
border: 1px solid gray;
border-top: none;
border-bottom: none;
box-shadow: 3px 0px 20px #333;
padding: 10px;
}
This has been tested with IE, Chrome, and Firefox on pages of various sizes and scrolling needs.
As Peter and Amro illustrate, you have to convert numeric values to formatted strings first in order to display them or concatenate them with other character strings. You can do this using the functions FPRINTF, SPRINTF, NUM2STR, and INT2STR.
With respect to getting ans = 3
as an output, it is probably because you are not assigning the output from answer
to a variable. If you want to get all of the output values, you will have to call answer
in the following way:
[out1,out2,out3] = answer(1,2);
This will place the value d
in out1
, the value e
in out2
, and the value f
in out3
. When you do the following:
answer(1,2)
MATLAB will automatically assign the first output d
(which has the value 3 in this case) to the default workspace variable ans
.
With respect to suggesting a good resource for learning MATLAB, you shouldn't underestimate the value of the MATLAB documentation. I've learned most of what I know on my own using it. You can access it online, or within your copy of MATLAB using the functions DOC, HELP, or HELPWIN.
Dictionary is the most common, but you can use other types of collections, e.g. System.Collections.Generic.SynchronizedKeyedCollection, System.Collections.Hashtable, or any KeyValuePair collection
I know this is late, but it does answer your original question.

Check that you are building a 64-bit process, and not a 32-bit one, which is the default compilation mode of Visual Studio. To do this, right click on your project, Properties -> Build -> platform target : x64. As any 32-bit process, Visual Studio applications compiled in 32-bit have a virtual memory limit of 2GB.
64-bit processes do not have this limitation, as they use 64-bit pointers, so their theoretical maximum address space (the size of their virtual memory) is 16 exabytes (2^64). In reality, Windows x64 limits the virtual memory of processes to 8TB. The solution to the memory limit problem is then to compile in 64-bit.
However, object’s size in Visual Studio is still limited to 2GB, by default. You will be able to create several arrays whose combined size will be greater than 2GB, but you cannot by default create arrays bigger than 2GB. Hopefully, if you still want to create arrays bigger than 2GB, you can do it by adding the following code to you app.config file:
<configuration>
<runtime>
<gcAllowVeryLargeObjects enabled="true" />
</runtime>
</configuration>
Though best way is to get it done will be using a window function, it can also be done using a simple correlated sub-query.

The accepted answer in 2008 recommended SIGAR. However, as a comment from 2014 (@Alvaro) says:
Be careful when using Sigar, there are problems on x64 machines... Sigar 1.6.4 is crashing: EXCEPTION_ACCESS_VIOLATION and it seems the library doesn't get updated since 2010
My recommendation is to use https://github.com/oshi/oshi
Or the answer mentioned above.
Wget 404 error also always happens if you want to download the pages from Wordpress-website by typing
wget -r http://somewebsite.com
If this website is built using Wordpress you'll get such an error:
ERROR 404: Not Found.
There's no way to mirror Wordpress-website because the website content is stored in the database and wget is not able to grab .php files. That's why you get Wget 404 error.
I know it's not this question's case, because Sam only wants to download a single picture, but it can be helpful for others.
Or just...
var response = (function() {
var a;
// calculate a
return a;
})();
In this case, the response variable receives the return value of the function. The function executes immediately.
You can use this construct if you want to populate a variable with a value that needs to be calculated. Note that all calculation happens inside the anonymous function, so you don't pollute the global namespace.
You could try:
.modal.modal-wide .modal-dialog {
width: 90%;
}
.modal-wide .modal-body {
overflow-y: auto;
}
Just add .modal-wide to your classes
A hash table totally works on the fact that practical computation follows random access machine model i.e. value at any address in memory can be accessed in O(1) time or constant time.
So, if I have a universe of keys (set of all possible keys that I can use in a application, e.g. roll no. for student, if it's 4 digit then this universe is a set of numbers from 1 to 9999), and a way to map them to a finite set of numbers of size I can allocate memory in my system, theoretically my hash table is ready.
Generally, in applications the size of universe of keys is very large than number of elements I want to add to the hash table(I don't wanna waste a 1 GB memory to hash ,say, 10000 or 100000 integer values because they are 32 bit long in binary reprsentaion). So, we use this hashing. It's sort of a mixing kind of "mathematical" operation, which maps my large universe to a small set of values that I can accomodate in memory. In practical cases, often space of a hash table is of the same "order"(big-O) as the (number of elements *size of each element), So, we don't waste much memory.
Now, a large set mapped to a small set, mapping must be many-to-one. So, different keys will be alloted the same space(?? not fair). There are a few ways to handle this, I just know the popular two of them:
Introduction to Algorithms by CLRS provides a very good insight on the topic.
You can solve this issue be adding max-width
:
#element {
width: 100vw;
height: 100vw;
max-width: 100%;
}
When you using CSS to make the wrapper full width using the code width: 100vw;
then you will notice a horizontal scroll in the page, and that happened because the padding
and margin
of html
and body
tags added to the wrapper size, so the solution is to add max-width: 100%
Let us first try to understand the root cause as to why it is happening in first place.
Why do I get an error or Uncaught TypeError: Cannot set property 'innerHTML' of null?
The browser always loads the entire HTML DOM from top to bottom. Any JavaScript code written inside the script
tags (present in head
section of your HTML file) gets executed by the browser rendering engine even before your whole DOM (various HTML element tags present within body tag) is loaded. The scripts present in head
tag are trying to access an element having id hello
even before it has actually been rendered in the DOM. So obviously, JavaScript failed to see the element and hence you end up seeing the null reference error.
How can you make it work as before?
You want to show the "hi" message on the page as soon as the user lands on your page for the first time. So you need to hook up your code at a point when you are completely sure of the fact that DOM is fully loaded and the hello
id element is accessible/available. It is achievable in two ways:
hello
id element is already loaded. You can achieve it by simply moving the script tag after all the DOM elements i.e. at the bottom where body
tag is ending. Since rendering happens from top to bottom so your scripts get executed in the end and you face no error. <!DOCTYPE HTML>_x000D_

The time problem has to do with the ID3 headers of the MP3 files, which is something your method isn't taking into account as the entire file is copied.
Do you have a language of choice that you want to use or doesn't it matter? That will affect what libraries are available that support the operations you want.
This was a Tomcat bug that resurfaced again with the Java 9 bytecode. The exact versions which fix this (for both Java 8/9 bytecode) are:
A decent implementation can be found at http://code.google.com/p/reallysimplehistory/. The only (but also) problem and bug it has is: in Internet Explorer modifying the location hash manually will reset the entire history stack (this is a browser issue and it cannot be solved).
Note, Internet Explorer 8 does have support for the "hashchange" event, and since it is becoming part of HTML5 you may expect other browsers to catch up.
For example, if I wanted to move all .txt files from one location to another ( on a Windows OS for instance ) I would do it something like this:
import shutil
import os,glob
inpath = 'R:/demo/in'
outpath = 'R:/demo/out'
os.chdir(inpath)
for file in glob.glob("*.txt"):
shutil.move(inpath+'/'+file,outpath)
SELECT p.LastName, p.FirstName, o.OrderNo
FROM persons AS p
LEFT JOIN
orders AS o
ON o.orderNo = p.p_id
UNION ALL
SELECT NULL, NULL, orderNo
FROM orders
WHERE orderNo NOT IN
(
SELECT p_id
FROM persons
)
You're missing ;
s. The general syntax if you put it all in one line would be:
if thing ; then ... ; else ... ; fi
The thing
can be pretty much anything that returns an exit code. The then
branch is taken if that thing
returns 0, the else
branch otherwise.
[
isn't syntax, it's the test
program (check out ls /bin/[
, it actually exists, man test
for the docs – although can also have a built-in version with different/additional features.) which is used to test various common conditions on files and variables. (Note that [[
on the other hand is syntax and is handled by your shell, if it supports it).
For your case, you don't want to use test
directly, you want to test something on the remote host. So try something like:
if ssh user@host test -e "$file" ; then ... ; else ... ; fi
please set dataType config property in your ajax call and give it another try!
another point is you are using ajax call setup configuration properties as string and it is wrong as reference site
$.ajax({

data : {
'numberOfWords' : 10
},
dataType:'json',
success : function(data) {

I hope be helpful!
Build.SERIAL
can be empty or sometimes return a different value (proof 1, proof 2) than what you can see in your device's settings.
If you want a more complete and robust solution, I've compiled every possible solution I could found in a single gist. Here's a simplified version of it :
public static String getSerialNumber() {
String serialNumber;
try {
Class<?> c = Class.forName("android.os.SystemProperties");
Method get = c.getMethod("get", String.class);
serialNumber = (String) get.invoke(c, "gsm.sn1");
if (serialNumber.equals(""))
serialNumber = (String) get.invoke(c, "ril.serialnumber");
if (serialNumber.equals(""))
serialNumber = (String) get.invoke(c, "ro.serialno");
if (serialNumber.equals(""))
serialNumber = (String) get.invoke(c, "sys.serialnumber");
if (serialNumber.equals(""))
serialNumber = Build.SERIAL;
// If none of the methods above worked
if (serialNumber.equals(""))
serialNumber = null;
} catch (Exception e) {
e.printStackTrace();
serialNumber = null;
}
return serialNumber;
}
I try to update the gist regularly whenever I can test on a new device or Android version. Contributions are welcome too.
We had the same issue, working from JS code (i.e. not from HTML anchor). This is how we solved that:
If needed, virtually alter current URL through $location
service. This might be useful if your destination is just a variation on the current URL, so that you can take advantage of $location
helper methods. E.g. we ran $location.search(..., ...)
to just change value of a querystring paramater.
Build up the new destination URL, using current $location.url()
if needed. In order to work, this new one had to include everything after schema, domain and port. So e.g. if you want to move to:
http://yourdomain.com/YourAppFolder/YourAngularApp/#/YourArea/YourAction?culture=en
then you should set URL as in:
var destinationUrl = '/YourAppFolder/YourAngularApp/#/YourArea/YourAction?culture=en';
(with the leading '/'
as well).
Assign new destination URL at low-level: $window.location.href = destinationUrl;
Force reload, still at low-level: $window.location.reload();
The two upvoted answers here show solutions for an Activity with navigation mode NAVIGATION_MODE_TABS
, but I had the same issue with a NAVIGATION_MODE_LIST
. It caused my Fragments to inexplicably lose their state when the screen orientation changed, which was really annoying. Thankfully, due to their helpful code I managed to figure it out.
Basically, when using a list navigation, ``onNavigationItemSelected()is automatically called when your activity is created/re-created, whether you like it or not. To prevent your Fragment's
onCreateView()from being called twice, this initial automatic call to
onNavigationItemSelected()should check whether the Fragment is already in existence inside your Activity. If it is, return immediately, because there is nothing to do; if it isn't, then simply construct the Fragment and add it to the Activity like you normally would. Performing this check prevents your Fragment from needlessly being created again, which is what causes
onCreateView()` to be called twice!
See my onNavigationItemSelected()
implementation below.
public class MyActivity extends FragmentActivity implements ActionBar.OnNavigationListener
{
private static final String STATE_SELECTED_NAVIGATION_ITEM = "selected_navigation_item";
private boolean mIsUserInitiatedNavItemSelection;
// ... constructor code, etc.
@Override
public void onRestoreInstanceState(Bundle savedInstanceState)
{
super.onRestoreInstanceState(savedInstanceState);
if (savedInstanceState.containsKey(STATE_SELECTED_NAVIGATION_ITEM))
{
getActionBar().setSelectedNavigationItem(savedInstanceState.getInt(STATE_SELECTED_NAVIGATION_ITEM));
}
}
@Override
public void onSaveInstanceState(Bundle outState)
{
outState.putInt(STATE_SELECTED_NAVIGATION_ITEM, getActionBar().getSelectedNavigationIndex());
super.onSaveInstanceState(outState);
}
@Override
public boolean onNavigationItemSelected(int position, long id)
{
Fragment fragment;
switch (position)
{
// ... choose and construct fragment here
}
// is this the automatic (non-user initiated) call to onNavigationItemSelected()
// that occurs when the activity is created/re-created?
if (!mIsUserInitiatedNavItemSelection)
{
// all subsequent calls to onNavigationItemSelected() won't be automatic
mIsUserInitiatedNavItemSelection = true;
// has the same fragment already replaced the container and assumed its id?
Fragment existingFragment = getSupportFragmentManager().findFragmentById(R.id.container);
if (existingFragment != null && existingFragment.getClass().equals(fragment.getClass()))
{
return true; //nothing to do, because the fragment is already there
}
}
getSupportFragmentManager().beginTransaction().replace(R.id.container, fragment).commit();
return true;
}
}
I borrowed inspiration for this solution from here.
I've created the PemUtils library that does exactly that. The code is available on GitHub and can be installed from NuGet:
PM> Install-Package PemUtils
or if you only want a DER converter:
PM> Install-Package DerConverter
Usage for reading a RSA key from PEM data:
using (var stream = File.OpenRead(path))
using (var reader = new PemReader(stream))
{
var rsaParameters = reader.ReadRsaKey();
// ...
}
Array.filter( document.getElementsByClassName('appBanner'), function(elem){ elem.style.visibility = 'hidden'; });

position: absolute
can be placed anywhere and remain there such as 0,0.
position: relative
is placed with offset from the location it is originally placed in the browser.
You can get the file name, but you cannot get the full client file-system path.
Try to access to the value
attribute of your file input
on the change
event.
Most browsers will give you only the file name, but there are exceptions like IE8 which will give you a fake path like: "C:\fakepath\myfile.ext"
and older versions (IE <= 6) which actually will give you the full client file-system path (due its lack of security).
document.getElementById('fileInput').onchange = function () {
alert('Selected file: ' + this.value);
};
In short the differences are the following:
Syntactical Differences Between Interface and Abstract Class:

Install sshpass using, apt-get install sshpass
then edit the script and put your linux machines IPs, usernames and password in respective order. After that run that script. Thats it ! This script will install VLC in all systems.

ES6 now supports the startsWith()
and endsWith()
method for checking beginning and ending of string
s. If you want to support pre-es6 engines, you might want to consider adding one of the suggested methods to the String
prototype.
if (typeof String.prototype.startsWith != 'function') {
String.prototype.startsWith = function (str) {
return this.match(new RegExp("^" + str));
};
}
if (typeof String.prototype.endsWith != 'function') {
String.prototype.endsWith = function (str) {
return this.match(new RegExp(str + "$"));
};
}
var str = "foobar is not barfoo";
console.log(str.startsWith("foob"); // true
console.log(str.endsWith("rfoo"); // true
Oddly, it works with some types of input. At least in Chrome,
<input type="checkbox" />
works fine, same as
<input type="radio" />
It's just type=text
and some others that don't work.
From cppreference, one of the std::unique_ptr
constructors is
explicit unique_ptr( pointer p ) noexcept;
So to create a new std::unique_ptr
is to pass a pointer to its constructor.
unique_ptr<int> uptr (new int(3));
Or it is the same as
int *int_ptr = new int(3);
std::unique_ptr<int> uptr (int_ptr);
The different is you don't have to clean up after using it. If you don't use std::unique_ptr
(smart pointer), you will have to delete it like this
delete int_ptr;
when you no longer need it or it will cause a memory leak.
In the C++ standard, cout
is defined in the std
namespace, so you need to either say std::cout
or put
using namespace std;
in your code in order to get at it.
However, this was not always the case, and in the past cout
was just in the global namespace (or, later on, in both global and std
). I would therefore conclude that your classes used an older C++ compiler.
Try the below code for delay
//MARK: First Way
func delayForWork() {
delay(3.0) {
print("delay for 3.0 second")
}
}
delayForWork()
// MARK: Second Way
DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
// your code here delayed by 0.5 seconds
}
Here are some options to convert the .csv files into one data.frame using R base and some of the available packages for reading files in R.
This is slower than the options below.
# Get the files names
files = list.files(pattern="*.csv")
# First apply read.csv, then rbind
myfiles = do.call(rbind, lapply(files, function(x) read.csv(x, stringsAsFactors = FALSE)))
Edit: - A few more extra choices using data.table
and readr
A fread()
version, which is a function of the data.table
package. This is by far the fastest option in R.
library(data.table)
DT = do.call(rbind, lapply(files, fread))
# The same using `rbindlist`
DT = rbindlist(lapply(files, fread))
Using readr, which is another package for reading csv files. It's slower than fread
, faster than base R but has different functionalities.
library(readr)
library(dplyr)
tbl = lapply(files, read_csv) %>% bind_rows()
Python3

I'm troubled by some of these responses. I think doubles and floats have a place in financial calculations. Certainly, when adding and subtracting non-fractional monetary amounts there will be no loss of precision when using integer classes or BigDecimal classes. But when performing more complex operations, you often end up with results that go out several or many decimal places, no matter how you store the numbers. The issue is how you present the result.
If your result is on the borderline between being rounded up and rounded down, and that last penny really matters, you should be probably be telling the viewer that the answer is nearly in the middle - by displaying more decimal places.
The problem with doubles, and more so with floats, is when they are used to combine large numbers and small numbers. In java,
System.out.println(1000000.0f + 1.2f - 1000000.0f);
results in
1.1875
Just add a new table
in the td
you want. Example: http://jsfiddle.net/AbE3Q/

<td>ABC</td>
<td>ABC</td>
<td>ABC</td>
<td>ABC</td>

<tr>
<td>Item1</td>
<td>Item2</td>

This answer is inspired by post Angular 2: Focus on newly added input element
Steps to set the focus on Html element in Angular2
Import ViewChildren in your Component
import { Input, Output, AfterContentInit, ContentChild,AfterViewInit, ViewChild, ViewChildren } from 'angular2/core';
Declare local template variable name for the html for which you want to set the focus
Following is the piece of code which I used for setting the focus
ngAfterViewInit() {vc.first.nativeElement.focus()}
Add #input
attribute to the DOM element you want to access.

There's a kind of hack-tastic way to do it if you have php enabled on your server. Change this line:
url: 'http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml',
to this line:
url: '/path/to/phpscript.php',
and then in the php script (if you have permission to use the file_get_contents() function):
<?php
header('Content-type: application/xml');
echo file_get_contents("http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml");
?>
Php doesn't seem to mind if that url is from a different origin. Like I said, this is a hacky answer, and I'm sure there's something wrong with it, but it works for me.
Edit: If you want to cache the result in php, here's the php file you would use:
<?php
$cacheName = 'somefile.xml.cache';
// generate the cache version if it doesn't exist or it's too old!
$ageInSeconds = 3600; // one hour
if(!file_exists($cacheName) || filemtime($cacheName) > time() + $ageInSeconds) {
$contents = file_get_contents('http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml');
file_put_contents($cacheName, $contents);
}
$xml = simplexml_load_file($cacheName);
header('Content-type: application/xml');
echo $xml;
?>
Caching code take from here.
You cannot treat ==
or ||
as chars, since they are not chars, but a sequence of chars.
You could make your switch...case work on strings instead.
If you need all the foreign keys of the user then use the following script
SELECT a.constraint_name, a.table_name, a.column_name, c.owner,
c_pk.table_name r_table_name, b.column_name r_column_name
FROM user_cons_columns a
JOIN user_constraints c ON a.owner = c.owner
AND a.constraint_name = c.constraint_name
JOIN user_constraints c_pk ON c.r_owner = c_pk.owner
AND c.r_constraint_name = c_pk.constraint_name
JOIN user_cons_columns b ON C_PK.owner = b.owner
AND C_PK.CONSTRAINT_NAME = b.constraint_name AND b.POSITION = a.POSITION
WHERE c.constraint_type = 'R'

Check and uncheck the USB Debugging option in the device. If that doesn't work unplug and plug in the USB a couple of times.
At some point, the device should show a message box to ask you to authorize the computer. Click yes and then the device will be authorized.
If you want to change whether it highlights the best fitting possibility, use:
Ctrl + Alt + Space
localStorage
is something that is kept on the client side. There is no data transmitted to the server side.
You can only get the data with JavaScript and you can send it to the server side with Ajax.
What is your PHP version? Extension "Mysql" was deprecated in PHP 5.5.0. Use extension Mysqli (like mysqli_query).
I used JMock early. I've tried Mockito at my last project and liked it. More concise, more cleaner. PowerMock covers all needs which are absent in Mockito, such as mocking a static code, mocking an instance creation, mocking final classes and methods. So I have all I need to perform my work.
Date input = new Date();
LocalDateTime conv=LocalDateTime.ofInstant(input.toInstant(), ZoneId.systemDefault());
LocalDate convDate=conv.toLocalDate();
The Date
instance does contain time too along with the date while LocalDate
doesn't. So you can firstly convert it into LocalDateTime
using its method ofInstant()
then if you want it without time then convert the instance into LocalDate
.
You can set the Main-Class attribute in the jar file's manifest to point to which file you want to run automatically.

When converting an excel file to CSV the date/time cell looks like this:
foo, 3/16/2016 10:38, bar,
To convert the datetime text value to datetime python object do this:
from datetime import datetime
date_object = datetime.strptime('3/16/2016 10:38', '%m/%d/%Y %H:%M') # excel format (CSV file)
print date_object will return 2005-06-01 13:33:00
I didn't understand your problem clearly but I think this is what you're looking for(Based on my understanding)
person = {"name"=>"BillGates", "company_name"=>"Microsoft", "position"=>"Chairman"}
person.delete_if {|key, value| key == "name"} #doing something if the key == "something"
Output: {"company_name"=>"Microsoft", "position"=>"Chairman"}
I wrote a library that can help with type convertions https://github.com/KromDaniel/jonson
js := jonson.New([]interface{}{55.6, 70.8, 10.4, 1, "48", "-90"})
js.SliceMap(func(jsn *jonson.JSON, index int) *jonson.JSON {
jsn.MutateToInt()
return jsn
}).SliceMap(func(jsn *jonson.JSON, index int) *jonson.JSON {
if jsn.GetUnsafeInt() > 50{
jsn.MutateToString()
}
return jsn
}) // ["55","70",10,1,48,-90]
I had a similar issue with my OLE DB Command and I resolved it by setting the ValidateExternalMetadata property within the component to False.
You can't. They simply do not work that way. A drop down menu must have one of its options selected at all times.
You could (although I don't recommend it) watch for a change event and then use JS to delete the first option if it is blank.
In my case, I wanted hours and minutes:
var duration = moment.duration(end.diff(startTime));
var hours = duration.hours(); //hours instead of asHours
var minutes = duration.minutes(); //minutes instead of asMinutes

The Easiest way :
HTML
<div ng-app="myApp" ng-controller="myCtrl">
<button ng-click="sendData();"> Send Data </button>
</div>
JavaScript
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $rootScope) {
function sendData($scope) {
var arrayData = ['sam','rumona','cubby'];
$rootScope.$emit('someEvent', arrayData);
}
});
app.controller('yourCtrl', function($scope, $rootScope) {
$rootScope.$on('someEvent', function(event, data) {
console.log(data);
});
});
</script>
If you have a multicore processor, both Visual Studio (2005 and later) as well as GCC support multi-processor compiles. It is something to enable if you have the hardware, for sure.
I often use the simplest way:
var variable;
if (variable === undefined){
console.log('Variable is undefined');
} else {
console.log('Variable is defined');
}
EDIT:
Without initializing the variable, exception will be thrown "Uncaught ReferenceError: variable is not defined..."
You want to git rebase -i
to perform an interactive rebase.
If you're currently on your "commit 1", and the commit you want to merge, "commit 2", is the previous commit, you can run git rebase -i HEAD~2
, which will spawn an editor listing all the commits the rebase will traverse. You should see two lines starting with "pick". To proceed with squashing, change the first word of the second line from "pick" to "squash". Then save your file, and quit. Git will squash your first commit into your second last commit.
Note that this process rewrites the history of your branch. If you are pushing your code somewhere, you'll have to git push -f
and anybody sharing your code will have to jump through some hoops to pull your changes.
Note that if the two commits in question aren't the last two commits on the branch, the process will be slightly different.
From requests 2.4.2 (https://pypi.python.org/pypi/requests), the "json" parameter is supported. No need to specify "Content-Type". So the shorter version:
requests.post('http://httpbin.org/post', json={'test': 'cheers'})
$array = 1..5 | foreach { $false }
Yes - different
chmod a+x
will add the exec bits to the file but will not touch other bits. For example file might be still unreadable to others
and group
.
chmod 755
will always make the file with perms 755
no matter what initial permissions were.
This may or may not matter for your script.
I'd say laziness. Arrays start at 0 (everyone knows that); the months of the year are an array, which leads me to believe that some engineer at Sun just didn't bother to put this one little nicety into the Java code.

Keep in mind that using
this
isn't working this way when using arrow functions or invoking methods/getters explicitly bound to custom value.
this
is referring to current instance.super
is basically referring to same instance, but somewhat addressing methods and getters written in context of some class current one is extending (by using the prototype of Foo's prototype).this.constructor

For those who want to access a file from an already loaded PowerShell session, either use Unblock-File to mark the file as safe (though you already need to have set a relaxed execution policy like Unrestricted
for this to work), or change the execution policy just for the current PowerShell session:
Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process
The standard SQL way is to use like:
where @stringVar like '%thisstring%'
That is in a query statement. You can also do this in TSQL:
if @stringVar like '%thisstring%'
#footer:after
{
content: "";
width: 40px;
height: 3px;
background-color: #529600;
left: 0;
position: relative;
display: block;
top: 10px;
}
colrm — remove columns from a file
To leave first two chars, just remove columns starting from 3
cat file | colrm 3
Can I tell the interface to default the properties I don't supply to null? What would let me do this
No. You cannot provide default values for interfaces or type aliases as they are compile time only and default values need runtime support
But values that are not specified default to undefined
in JavaScript runtimes. So you can mark them as optional:
interface IX {
a: string,
b?: any,
c?: AnotherType
}
And now when you create it you only need to provide a
:
let x: IX = {
a: 'abc'
};
You can provide the values as needed:
x.a = 'xyz'
x.b = 123
x.c = new AnotherType()
There is a command
svn revert -R .
OR
you can use the --depth=infinity, which is actually same as above:
svn revert --depth=infinity
svn revert
is inherently dangerous, since its entire purpose is to throw away data—namely, your uncommitted changes. Once you've reverted, Subversion provides no way to get back those uncommitted changes
Sets require their items to be hashable. Out of types predefined by Python only the immutable ones, such as strings, numbers, and tuples, are hashable. Mutable types, such as lists and dicts, are not hashable because a change of their contents would change the hash and break the lookup code.
Since you're sorting the list anyway, just place the duplicate removal after the list is already sorted. This is easy to implement, doesn't increase algorithmic complexity of the operation, and doesn't require changing sublists to tuples:
def uniq(lst):
last = object()
for item in lst:
if item == last:
continue
yield item
last = item
def sort_and_deduplicate(l):
return list(uniq(sorted(l, reverse=True)))
when i generate rails g controller i got the same error. After that when do the following changes on Gemfile(in rails 4) everything went smooth.The changes i made was
gem 'execjs'
gem 'therubyracer', "0.11.4"
After that i can able to run the server and able to do all basic operations on the application.
The question title says "How can I simulate an anchor click in jQuery?". Well, you can use the "trigger" or "triggerHandler" methods, like so:
<script type="text/javascript" src="path/to/jquery.js"></script>
<script type="text/javascript" src="path/to/thickbox.js"></script>
<script type="text/javascript">
$(function() {
$('#btn').click(function() {
$('#thickboxId').triggerHandler('click');
})
})
</script>
...
<input id="btn" type="button" value="Click me">
<a id="thickboxId" href="myScript.php" class="thickbox" title="">Link</a>
Not tested, this actual script, but I've used trigger
et al before, and they worked a'ight.
UPDATE
triggerHandler
doesn't actually do what the OP wants. I think 1421968 provides the best answer to this question.

4 Things You Must Do When Putting HTML in JSON:
1) Escape quotation marks used around HTML attributes like so
<img src=\"someimage.png\" />
2) Escape the forward slash in HTML end tags.
<div>Hello World!<\/div>.
This is an ancient artifact of an old HTML spec that didn't want HTML parsers to get confused when putting strings in a<SCRIPT>
tag. For some reason, today’s browsers still like it.3) This one was totally bizarre. You should include a space between the tag name and the slash on self-closing tags. I have no idea why this is, but on MOST modern browsers, if you try using javascript to append a
<li>
tag as a child of an unordered list that is formatted like so:<ul/>
, it won't work. It gets added to the DOM after the ul tag. But, if the code looks like this:<ul />
(notice the space before the /), everything works fine. Very strange indeed.4) Be sure to encode any quotation marks that might be included in (bad) HTML content. This is the only thing that would really break the JSON by accidentally terminating the string early. Any
"
characters should be encoded as"
if it is meant to be included as HTML content.
You can't "add" values to an array as the array length is immutable. You can set values at specific array positions.
If you know how to do it with one-dimensional arrays then you know how to do it with n-dimensional arrays: There are no n-dimensional arrays in Java, only arrays of arrays (of arrays...).
But you can chain the index operator for array element access.
String[][] x = new String[2][];
x[0] = new String[1];
x[1] = new String[2];
x[0][0] = "a1";
// No x[0][1] available
x[1][0] = "b1";
x[1][1] = "b2";
Note the dimensions of the child arrays don't need to match.
/*
If your delimiters are slash-based, escape it:
\/*
*
means "0 or more of the previous repeatable pattern", which can be a single character, a character class or a group.
Best and easiest solution:
For each page you want your respective link to change color to until switched, put an internal style in EACH PAGE for the VISITED attribute and make each an individual class in order to differentiate between links so you don't apply the feature to all accidentally. We'll use white as an example:
<style type="text/css">
.link1 a:visited {color:#FFFFFF;text-decoration:none;}
</style>
For all other attributes such as LINK, ACTIVE and HOVER, you can keep those in your style.css. You'll want to include a VISITED there as well for the color you want the link to turn back to when you click a different link.
The Problem is with URLPattern
Change your URL pattern on your servlet mapping from "/" to "/*"
for ( i = 0; i < total.length; i++ );
^-- remove the semi-colon here
With this semi-colon, the loop loops until i == total.length
, doing nothing, and then what you thought was the body of the loop is executed.
For testing purposes I use the following:
//return assoc array when called from outside the class it will only contain public properties and values
var_dump(get_object_vars($obj));
You cannot "edit" a default theme, they are "locked in"
However, you can copy it into your own custom theme, with the exact modifications you'd like.
For more info, see these articles: https://code.visualstudio.com/Docs/customization/themes https://code.visualstudio.com/docs/extensions/install-extension#_your-extensions-folder
If all you want to change is the colors for C++ code, you should look at overwriting the c++ support colorizer. For info about that, go here: https://code.visualstudio.com/docs/customization/colorizer
EDIT: The dark theme is found here: https://github.com/Microsoft/vscode/tree/80f8000c10b4234c7b027dccfd627442623902d2/extensions/theme-colorful-defaults
EDIT2: To clarify:
A different perspective to the same problem away from Javascript and using php:
<a data-toggle="modal" href="#myModal">LINK</a>
<div class="modal fade" tabindex="-1" aria-labelledby="gridSystemModalLabel" id="myModal" role="dialog" style="max-width: 90%;">
<div class="modal-dialog" style="text-align: left;">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Title</h4>
</div>
<div class="modal-body">
<?php include( 'remotefile.php'); ?>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
and put in the remote.php file your basic html source.
In my case settings.gradle
was missing.
Save the file and put it at the top level folder in your project, even you can copy from another project too.
Screenshot reference:
Hope this would save your time.
As mentioned, one way is to use
new Integer(my_int_value)
But you should not call the constructor for wrapper classes directly
So, modify the code accordingly:
mBitmapCache.put(Integer.valueOf(R.drawable.bg1),object);
The question doesn't specify a shell, so for those using fish (friendly interactive shell):
if command -v foo > /dev/null
echo exists
else
echo does not exist
end
For basic POSIX compatibility, we use the -v
flag which is an alias for --search
or -s
.
INNER JOIN = JOIN
INNER JOIN is the default if you don't specify the type when you use the word JOIN.
You can also use LEFT OUTER JOIN or RIGHT OUTER JOIN, in which case the word OUTER is optional, or you can specify CROSS JOIN.
OR
For an inner join, the syntax is:
SELECT ...
FROM TableA
[INNER] JOIN TableB(in other words, the "INNER" keyword is optional - results are the same with or without it)
SELECT
category,
COUNT(*) AS `num`
FROM
posts
GROUP BY
category
You need jdbc4 then you can use setArray!
In my case it didn't worked, as the UUID Datatype in postgres seems to still have its weak spots, but for the usual types it works.
ps.setArray(1, connection.createArrayOf("$VALUETYPE",myValuesAsArray));
Of course replace $VALUETYPE and myValuesAsArray with the correct values.
Remark following Marks comment:
Your database and the driver needs to support this! I tried Postgres 9.4 but I think this has been introduced earlier. You need a jdbc 4 driver, otherwise setArray won't be available. I used the postgresql 9.4-1201-jdbc41 driver that ships with spring boot
Yes, this is confusing...
According to this blog post, it looks like this is an omission from WPF.
To make it work you need to use a style:
<Border Name="ClearButtonBorder" Grid.Column="1" CornerRadius="0,3,3,0">
<Border.Style>
<Style>
<Setter Property="Border.Background" Value="Blue"/>
<Style.Triggers>
<Trigger Property="Border.IsMouseOver" Value="True">
<Setter Property="Border.Background" Value="Green" />
</Trigger>
</Style.Triggers>
</Style>
</Border.Style>
<TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="X" />
</Border>
I guess this problem isn't that common as most people tend to factor out this sort of thing into a style, so it can be used on multiple controls.
I use this way (for example):
$(document).on('click', '#save', function () {
var cont = true;
$('.field').each(function () {
if ($(this).val() === '') {
alert('Please fill out all fields');
cont = false;
return false;
}
});
if (cont === false) {
return false;
}
/* commands block */
});
if cont isn't false runs commands block

If you are targeting ASP.NET Core that does not support RijndaelManaged
yet, you can use IDataProtectionProvider
.
First, configure your application to use data protection:
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddDataProtection();
}
// ...
}
Then you'll be able to inject IDataProtectionProvider
instance and use it to encrypt/decrypt data:
public class MyService : IService
{
private const string Purpose = "my protection purpose";
private readonly IDataProtectionProvider _provider;
public MyService(IDataProtectionProvider provider)
{
_provider = provider;
}
public string Encrypt(string plainText)
{
var protector = _provider.CreateProtector(Purpose);
return protector.Protect(plainText);
}
public string Decrypt(string cipherText)
{
var protector = _provider.CreateProtector(Purpose);
return protector.Unprotect(cipherText);
}
}
See this article for more details.
Where I work we have been using this method on all of our repositories for a few years without any problems (except when we create a new repository and forget to set it up this way):
Change the group id of the repository to a group shared by all users who are allowed to push to it:
chgrp -R shared_group /git/our_repos
chmod -R g+w /git/our_repos
Set the setgid bit on all directories in the repository so that new files/directories keep the same group:
find /git/our_repos -type d -exec chmod g+s {} +
Add this line to the pre-receive hook in the repository to ensure new file permissions allow group read/write:
umask 007
Try Ryan Fait's "Sticky Footer" solution,
http://ryanfait.com/sticky-footer/

Works across IE, Firefox, Chrome, Safari and supposedly Opera too, but haven't tested that. It's a great solution. Very easy and reliable to implement.
first of all you need to go in your ssh directory
for this type following command in your terminal in mac or whatever you use in window
cd ~/.ssh
now it is in the ssh
here you can find all you ssh key/files related to your all projects. now, type the following command to show you if any ssh key available
ls
this will show you all available ssh, in my case there were two
now, you will need to start an agent to add a ssh in it. For this type following command
eval "$(ssh-agent -s)"
now last but not least you will add a ssh in this agent type following command
ssh-add ~/.ssh/your-ssh
replace
replace your-ssh with your ssh file name which you got a list form second step
ls command
I tried to use the Cast Extension (see https://stackoverflow.com/users/247402/stacker) in a situation where the Target Type contains a Property that is not present in the Source Type. It did not work, I'm not sure why. I refactored to the following extension that did work for my situation:
public static T Casting<T>(this Object source)
{
Type sourceType = source.GetType();
Type targetType = typeof(T);
var target = Activator.CreateInstance(targetType, false);
var sourceMembers = sourceType.GetMembers()
.Where(x => x.MemberType == MemberTypes.Property)
.ToList();
var targetMembers = targetType.GetMembers()
.Where(x => x.MemberType == MemberTypes.Property)
.ToList();
var members = targetMembers
.Where(x => sourceMembers
.Select(y => y.Name)
.Contains(x.Name));
PropertyInfo propertyInfo;
object value;
foreach (var memberInfo in members)
{
propertyInfo = typeof(T).GetProperty(memberInfo.Name);
value = source.GetType().GetProperty(memberInfo.Name).GetValue(source, null);
propertyInfo.SetValue(target, value, null);
}
return (T)target;
}
Note that I changed the name of the extension as the Name Cast conflicts with results from Linq. Hat tip https://stackoverflow.com/users/2093880/usefulbee

Q) Code was working fine in Intellj but failing in command line.
Sol) Add dependencies of jersey as a direct dependency rather than a transient one.
Reasoning: Since, it was working fine with IntelliJ, dependencies are correctly configured.
Get required dependencies by one of the following:
mvn dependency:tree
Now, add those problematic jersey dependencies explicitly.
You could use urllib as @roippi said:
import urllib2
data = '{"nw_src": "10.0.0.1/32", "nw_dst": "10.0.0.2/32", "nw_proto": "ICMP", "actions": "ALLOW", "priority": "10"}'
url = 'http://localhost:8080/firewall/rules/0000000000000001'
req = urllib2.Request(url, data, {'Content-Type': 'application/json'})
f = urllib2.urlopen(req)
for x in f:
print(x)
f.close()
Another approach is keep that element, change the text, then append that element back
const star_icon = $(li).find('.stars svg')
$(li).find('.stars').text(repo.stargazers_count).append(star_icon)

Since C++17 std::map
offers two new insertion methods: insert_or_assign()
and try_emplace()
, as also mentioned in the comment by sp2danny.
insert_or_assign()
Basically, insert_or_assign()
is an "improved" version of operator[]
. In contrast to operator[]
, insert_or_assign()
doesn't require the map's value type to be default constructible. For example, the following code doesn't compile, because MyClass
does not have a default constructor:
class MyClass {
public:
MyClass(int i) : m_i(i) {};
int m_i;
};
int main() {
std::map<int, MyClass> myMap;
// VS2017: "C2512: 'MyClass::MyClass' : no appropriate default constructor available"
// Coliru: "error: no matching function for call to 'MyClass::MyClass()"
myMap[0] = MyClass(1);
return 0;
}
However, if you replace myMap[0] = MyClass(1);
by the following line, then the code compiles and the insertion takes place as intended:
myMap.insert_or_assign(0, MyClass(1));
Moreover, similar to insert()
, insert_or_assign()
returns a pair<iterator, bool>
. The Boolean value is true
if an insertion occurred and false
if an assignment was done. The iterator points to the element that was inserted or updated.
try_emplace()
Similar to the above, try_emplace()
is an "improvement" of emplace()
. In contrast to emplace()
, try_emplace()
doesn't modify its arguments if insertion fails due to a key already existing in the map. For example, the following code attempts to emplace an element with a key that is already stored in the map (see *):
int main() {
std::map<int, std::unique_ptr<MyClass>> myMap2;
myMap2.emplace(0, std::make_unique<MyClass>(1));
auto pMyObj = std::make_unique<MyClass>(2);
auto [it, b] = myMap2.emplace(0, std::move(pMyObj)); // *
if (!b)
std::cout << "pMyObj was not inserted" << std::endl;
if (pMyObj == nullptr)
std::cout << "pMyObj was modified anyway" << std::endl;
else
std::cout << "pMyObj.m_i = " << pMyObj->m_i << std::endl;
return 0;
}
Output (at least for VS2017 and Coliru):
pMyObj was not inserted
pMyObj was modified anyway
As you can see, pMyObj
no longer points to the original object. However, if you replace auto [it, b] = myMap2.emplace(0, std::move(pMyObj));
by the the following code, then the output looks different, because pMyObj
remains unchanged:
auto [it, b] = myMap2.try_emplace(0, std::move(pMyObj));
Output:
pMyObj was not inserted
pMyObj pMyObj.m_i = 2
Please note: I tried to keep my explanations as short and simple as possible to fit them into this answer. For a more precise and comprehensive description, I recommend reading this article on Fluent C++.
Here is an example of implementing stack in java (Array Based implementation):
public class MyStack extends Throwable{
/**
*
*/
private static final long serialVersionUID = -4433344892390700337L;
protected static int top = -1;
protected static int capacity;
protected static int size;
public int stackDatas[] = null;
public MyStack(){
stackDatas = new int[10];
capacity = stackDatas.length;
}
public static int size(){
if(top < 0){
size = top + 1;
return size;
}
size = top+1;
return size;
}
public void push(int data){
if(capacity == size()){
System.out.println("no memory");
}else{
stackDatas[++top] = data;
}
}
public boolean topData(){
if(top < 0){
return true;
}else{
System.out.println(stackDatas[top]);
return false;
}
}
public void pop(){
if(top < 0){
System.out.println("stack is empty");
}else{
int temp = stackDatas[top];
stackDatas = ArrayUtils.remove(stackDatas, top--);
System.out.println("poped data---> "+temp);
}
}
public String toString(){
String result = "[";
if(top<0){
return "[]";
}else{
for(int i = 0; i< size(); i++){
result = result + stackDatas[i] +",";
}
}
return result.substring(0, result.lastIndexOf(",")) +"]";
}
}
calling MyStack:
public class CallingMyStack {
public static MyStack ms;
public static void main(String[] args) {
ms = new MyStack();
ms.push(1);
ms.push(2);
ms.push(3);
ms.push(4);
ms.push(5);
ms.push(6);
ms.push(7);
ms.push(8);
ms.push(9);
ms.push(10);
System.out.println("size: "+MyStack.size());
System.out.println("List---> "+ms);
System.out.println("----------");
ms.pop();
ms.pop();
ms.pop();
ms.pop();
System.out.println("List---> "+ms);
System.out.println("size: "+MyStack.size());
}
}
output:
size: 10
List---> [1,2,3,4,5,6,7,8,9,10]
----------
poped data---> 10
poped data---> 9
poped data---> 8
poped data---> 7
List---> [1,2,3,4,5,6]

is probably not the best choice for this. What I would do is use pyplot.draw()
instead. You also might want to include a small time delay (e.g., time.sleep(0.05)
) in the loop so that you can see the plots happening. If I make these changes to your example it works for me and I see each point appearing one at a time.
I have made this simple test with outerHTML being tokimon solution (without clone), and outerHTML2 being jessica solution (clone)
console.time("outerHTML");
for(i=0;i<1000;i++)
{
var html = $("<span style='padding:50px; margin:50px; display:block'><input type='text' title='test' /></span>").outerHTML();
}
console.timeEnd("outerHTML");
console.time("outerHTML2");
for(i=0;i<1000;i++)
{
var html = $("<span style='padding:50px; margin:50px; display:block'><input type='text' title='test' /></span>").outerHTML2();
}
console.timeEnd("outerHTML2");
and the result in my chromium (Version 20.0.1132.57 (0)) browser was
outerHTML: 81ms
outerHTML2: 439ms
but if we use tokimon solution without the native outerHTML function (which is now supported in probably almost every browser)
we get
outerHTML: 594ms
outerHTML2: 332ms
and there are gonna be more loops and elements in real world examples, so the perfect combination would be
$.fn.outerHTML = function()
{
$t = $(this);
if( "outerHTML" in $t[0] ) return $t[0].outerHTML;
else return $t.clone().wrap('<p>').parent().html();
}
so clone method is actually faster than wrap/unwrap method

I think "works fine in Firefox" is in the Quirks mode rendering only. In the Standard mode rendering, that might not work fine in Firefox too.
percentage depends on "containing block", instead of viewport.
The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the value computes to 'auto'.
so
#container { height: auto; }
#container #mainContentsWrapper { height: n%; }
#container #sidebarWrapper { height: n%; }
means
#container { height: auto; }
#container #mainContentsWrapper { height: auto; }
#container #sidebarWrapper { height: auto; }
To stretch to 100% height of viewport, you need to specify the height of the containing block (in this case, it's #container). Moreover, you also need to specify the height to body and html, because initial Containing Block is "UA-dependent".
All you need is...
html, body { height:100%; }
#container { height:100%; }
self.tableView.tableHeaderView = segmentedControl;
If you want it to obey your width and height properly though enclose your segmentedControl in a UIView first as the tableView likes to mangle your view a bit to fit the width.
You are using ES6 Module syntax.
This means your environment (e.g. node.js) must support ES6 Module syntax.
NodeJS uses CommonJS Module syntax (module.exports
) not ES6 module syntax (export
keyword).
Solution:
babel
npm package to transpile your ES6 to a commonjs
targetor
Examples of CommonJS syntax are (from flaviocopes.com/commonjs/):
exports.uppercase = str => str.toUpperCase()
exports.a = 1
I had this issue when trying to convert an existing varchar
column to enum
. For me the issue was that there were existing values for that column that were not part of the enum
's list of accepted values. So if your enum
will only allow values, say ('dog', 'cat')
but there is a row with bird
in your table, the MODIFY COLUMN
will fail with this error.
Noticed your comment about using it for email validation and needing a plugin, the validation plugin may help you, its located at http://bassistance.de/jquery-plugins/jquery-plugin-validation/, it comes with a e-mail rule as well.
Short answer: Yes. Use Python's urllib to pull the historical data pages for the stocks you want. Go with Yahoo! Finance; Google is both less reliable, has less data coverage, and is more restrictive in how you can use it once you have it. Also, I believe Google specifically prohibits you from scraping the data in their ToS.
Longer answer: This is the script I use to pull all the historical data on a particular company. It pulls the historical data page for a particular ticker symbol, then saves it to a csv file named by that symbol. You'll have to provide your own list of ticker symbols that you want to pull.
import urllib
base_url = "http://ichart.finance.yahoo.com/table.csv?s="
def make_url(ticker_symbol):
return base_url + ticker_symbol
output_path = "C:/path/to/output/directory"
def make_filename(ticker_symbol, directory="S&P"):
return output_path + "/" + directory + "/" + ticker_symbol + ".csv"
def pull_historical_data(ticker_symbol, directory="S&P"):
try:
urllib.urlretrieve(make_url(ticker_symbol), make_filename(ticker_symbol, directory))
except urllib.ContentTooShortError as e:
outfile = open(make_filename(ticker_symbol, directory), "w")
outfile.write(e.content)
outfile.close()

not sure if the last one still applies ... it was one big night mare in a project I worked on some time ago.
This is a classic case of divitis - you don't need a div to be clickable, just give the <a>
tag a class. Then edit the CSS of the class to display:block, and define a height and width like a lot of other answers have mentioned.
The <a>
tag works perfectly well on its own, so you don't need an extra level of mark-up on the page.
I used this in my application
Image icon = new Image(getClass().getResourceAsStream("icon.png"));
window.getIcons().add(icon);
Here window is the stage.
Here is another solution based on vh
, or viewpoint height
, for details visit CSS units. It is based on this solution, which uses flex instead.

The units are vw , vh, vmax, vmin. Basically, each unit is equal to 1% of viewport size. So, as the viewport changes, the browser computes that value and adjusts accordingly.
You may find more information here:
Specifically:
1vw (viewport width) = 1% of viewport width 1vh (viewport height) = 1% of viewport height 1vmin (viewport minimum) = 1vw or 1vh, whatever is smallest 1vmax (viewport minimum) = 1vw or 1vh, whatever is largest

Let us put it clear that most of the time in production code, we use abstract factory pattern because class A is programmed with interface B. And A needs to create instances of B. So A has to have a factory object to produce instances of B. So A is not dependent on any concrete instance of B. Hope it helps.
CORRECTION: I found out that the above solution is terrible. Especially when your phone is slow. And here, I found another solution: calculate out the px value of the element, including the margins and paddings: dp to px: https://stackoverflow.com/a/6327095/1982712
or dimens.xml to px: https://stackoverflow.com/a/16276351/1982712
sp to px: https://stackoverflow.com/a/9219417/1982712 (reverse the solution)
or dimens to px: https://stackoverflow.com/a/16276351/1982712
and that's it.
Debug and Release are just labels for different solution configurations. You can add others if you want. A project I once worked on had one called "Debug Internal" which was used to turn on the in-house editing features of the application. You can see this if you go to Configuration Manager...
(it's on the Build
menu). You can find more information on MSDN Library under Configuration Manager Dialog Box.
Each solution configuration then consists of a bunch of project configurations. Again, these are just labels, this time for a collection of settings for your project. For example, our C++ library projects have project configurations called "Debug", "Debug_Unicode", "Debug_MT", etc.
The available settings depend on what type of project you're building. For a .NET project, it's a fairly small set: #define
s and a few other things. For a C++ project, you get a much bigger variety of things to tweak.
In general, though, you'll use "Debug" when you want your project to be built with the optimiser turned off, and when you want full debugging/symbol information included in your build (in the .PDB file, usually). You'll use "Release" when you want the optimiser turned on, and when you don't want full debugging information included.

The Date
object itself will contain timezone anyway, and the returned result is the effect of converting it to string in a default way. I.e. you cannot create a date object without timezone. But what you can do is mimic the behavior of Date
object by creating your own one.
This is, however, better to be handed over to libraries like moment.js.

I've run into this need on several Joomla project. The simplest way I've found to address is to add a hidden input field to my template:
<input type="hidden" id="baseurl" name="baseurl" value="<?php echo $this->baseurl; ?>" />
When I need the value in JavaScript:
var baseurl = document.getElementById('baseurl').value;
Not as fancy as using pure JavaScript but simple and gets the job done.

It is interesting to note that getCanonicalName()
and getSimpleName()
can raise InternalError
when the class name is malformed. This happens for some non-Java JVM languages, e.g., Scala.
Consider the following (Scala 2.11 on Java 8):
scala> case class C()
defined class C
scala> val c = C()
c: C = C()
scala> c.getClass.getSimpleName
java.lang.InternalError: Malformed class name
at java.lang.Class.getSimpleName(Class.java:1330)
... 32 elided
scala> c.getClass.getCanonicalName
java.lang.InternalError: Malformed class name
at java.lang.Class.getSimpleName(Class.java:1330)
at java.lang.Class.getCanonicalName(Class.java:1399)
... 32 elided
scala> c.getClass.getName
res2: String = C
This can be a problem for mixed language environments or environments that dynamically load bytecode, e.g., app servers and other platform software.
How about simply (Please note, come up with a better name for the class name this is simply an example):
.centerText{
text-align: center;
}
<div>
<table style="width:100%">
<tbody>
<tr>
<td class="centerText">Cell 1</td>
<td>Cell 2</td>
</tr>
<tr>
<td class="centerText">Cell 3</td>
<td>Cell 4</td>
</tr>
</tbody>

You can place the css
in a separate file, which is recommended.
In my example, I created a file called styles.css
and placed my css
rules in it.
Then include it in the html document in the <head>
section as follows:
<head>
<link href="styles.css" rel="stylesheet" type="text/css">
</head>
The alternative, not creating a seperate css file, not recommended at all...
Create <style>
block in your <head>
in the html document. Then just place your rules there.
<head>
<style type="text/css">
.centerText{
text-align: center;
}
</style>
</head>
In this tutorial is explained how to consume a web api with C#, in this example a console application is used, but you can also use another web api to consume of course.
http://www.asp.net/web-api/overview/web-api-clients/calling-a-web-api-from-a-net-client
You should have a look at the HttpClient
HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost/yourwebapi");
Make sure your requests ask for the response in JSON using the Accept header like this:
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
Now comes the part that differs from the tutorial, make sure you have the same objects as the other WEB API
, if not, then you have to map the objects to your own objects. ASP.NET
will convert the JSON
you receive to the object you want it to be.
HttpResponseMessage response = client.GetAsync("api/yourcustomobjects").Result;
if (response.IsSuccessStatusCode)
{
var yourcustomobjects = response.Content.ReadAsAsync<IEnumerable<YourCustomObject>>().Result;
foreach (var x in yourcustomobjects)
{
//Call your store method and pass in your own object
SaveCustomObjectToDB(x);
}
}
else
{
//Something has gone wrong, handle it here
}
please note that I use .Result
for the case of the example. You should consider using the async
await
pattern here.
-First Move Your Code Files in side the "src" Folder
-Make sure your Main method is declared like the following
public class Main {
public static void main(String []args){
}
}
then:
and it should work
My favorite method:
CONTAINER_ID=$(docker ps | grep <string> | awk '{ print $1 }' | xargs docker inspect -f '{{.Id}}')
mv -f file.txt /var/lib/docker/devicemapper/mnt/$CONTAINER_ID/rootfs/root/file.txt
or
mv -f file.txt /var/lib/docker/aufs/mnt/$CONTAINER_ID/rootfs/root/file.txt
I think this statement might do what you want.
INSERT INTO newTableName (SELECT column1, column2, column3 FROM oldTable);
Like this:
{% if age > 18 %}
{% with patient as p %}
<my html here>
{% endwith %}
{% else %}
{% with patient.parent as p %}
<my html here>
{% endwith %}
{% endif %}
If the html is too big and you don't want to repeat it, then the logic would better be placed in the view. You set this variable and pass it to the template's context:
p = (age > 18 && patient) or patient.parent
and then just use {{ p }} in the template.
//
is unconditionally "flooring division", e.g:
>>> 4.0//1.5
2.0
As you see, even though both operands are float
s, //
still floors -- so you always know securely what it's going to do.
Single /
may or may not floor depending on Python release, future imports, and even flags on which Python's run, e.g.:
$ python2.6 -Qold -c 'print 2/3'
0
$ python2.6 -Qnew -c 'print 2/3'
0.666666666667
As you see, single /
may floor, or it may return a float, based on completely non-local issues, up to and including the value of the -Q
flag...;-).
So, if and when you know you want flooring, always use //
, which guarantees it. If and when you know you don't want flooring, slap a float()
around other operand and use /
. Any other combination, and you're at the mercy of version, imports, and flags!-)
A checkbox does not have background color.
But to add the effect, you may wrap each checkbox with a div

Step 1) Go to web browser, open your developer account. Go to Certificates, Identifiers & Profiles. Select Certificates / Production. You will see the certificate that was missing private key listed there. Click Revoke. And follow the instructions to remove this certificate. Step 2) That's it! go back to Xcode to Validate you app. It will now ask you to generate a new certificate. Now you happily uploading your apps.
Since .net45 you can use the LeaveOpen
constructor argument of StreamWriter
and still use the using
statement. Example:
using (var ms = new MemoryStream())
{
using (var sw = new StreamWriter(ms, Encoding.UTF8, 1024, true))
{
sw.WriteLine("data");
sw.WriteLine("data 2");
}
ms.Position = 0;
using (var sr = new StreamReader(ms))
{
Console.WriteLine(sr.ReadToEnd());
}
}
Interestingly enough I tried both of these in LinqPad and the variant using group from Dmitry Gribkov by appears to be quicker. (also the final distinct is not required as the result is already distinct.
My (somewhat simple) code was:
public class Pair
{
public int id {get;set;}
public string Arb {get;set;}
}
void Main()
{
var theList = new List<Pair>();
var randomiser = new Random();
for (int count = 1; count < 10000; count++)
{
theList.Add(new Pair
{
id = randomiser.Next(1, 50),
Arb = "not used"
});
}
var timer = new Stopwatch();
timer.Start();
var distinct = theList.GroupBy(c => c.id).Select(p => p.First().id);
timer.Stop();
Debug.WriteLine(timer.Elapsed);
timer.Start();
var otherDistinct = theList.Select(p => p.id).Distinct();
timer.Stop();
Debug.WriteLine(timer.Elapsed);
}

You don't need to write a program to do this in Linux. Just pipe the serial port through netcat:
netcat www.example.com port </dev/ttyS0 >/dev/ttyS0
Just replace the address and port information. Also, you may be using a different serial port (i.e. change the /dev/ttyS0
part). You can use the stty or setserial commands to change the parameters of the serial port (baud rate, parity, stop bits, etc.).
WIth the Help of @excray's comment, I manage to figure it out the answer, What we need to do is actually write a simple for loop to iterate over the two arrays that represent the train data and test data.
First implement a simple lambda function to hold formula for the cosine calculation:
cosine_function = lambda a, b : round(np.inner(a, b)/(LA.norm(a)*LA.norm(b)), 3)
And then just write a simple for loop to iterate over the to vector, logic is for every "For each vector in trainVectorizerArray, you have to find the cosine similarity with the vector in testVectorizerArray."
from sklearn.feature_extraction.text import CountVectorizer
from sklearn.feature_extraction.text import TfidfTransformer
from nltk.corpus import stopwords
import numpy as np
import numpy.linalg as LA
train_set = ["The sky is blue.", "The sun is bright."] #Documents
test_set = ["The sun in the sky is bright."] #Query
stopWords = stopwords.words('english')
vectorizer = CountVectorizer(stop_words = stopWords)
#print vectorizer
transformer = TfidfTransformer()
#print transformer
trainVectorizerArray = vectorizer.fit_transform(train_set).toarray()
testVectorizerArray = vectorizer.transform(test_set).toarray()
print 'Fit Vectorizer to train set', trainVectorizerArray
print 'Transform Vectorizer to test set', testVectorizerArray
cx = lambda a, b : round(np.inner(a, b)/(LA.norm(a)*LA.norm(b)), 3)
for vector in trainVectorizerArray:
print vector
for testV in testVectorizerArray:
print testV
cosine = cx(vector, testV)
print cosine
transformer.fit(trainVectorizerArray)
print
print transformer.transform(trainVectorizerArray).toarray()
transformer.fit(testVectorizerArray)
print
tfidf = transformer.transform(testVectorizerArray)
print tfidf.todense()
Here is the output:
Fit Vectorizer to train set [[1 0 1 0]
[0 1 0 1]]
Transform Vectorizer to test set [[0 1 1 1]]

[0 1 1 1]

Explanation of Serialize and Deserialize using Python
In python, pickle module is used for serialization. So, the serialization process is called pickling in Python. This module is available in Python standard library.
Serialization using pickle
import pickle
#the object to serialize
example_dic={1:"6",2:"2",3:"f"}
#where the bytes after serializing end up at, wb stands for write byte
pickle_out=open("dict.pickle","wb")
#Time to dump
pickle.dump(example_dic,pickle_out)
#whatever you open, you must close
pickle_out.close()
The PICKLE file (can be opened by a text editor like notepad) contains this (serialized data):
€}q (KX 6qKX 2qKX fqu.
Deserialization using pickle
import pickle
pickle_in=open("dict.pickle","rb")
get_deserialized_data_back=pickle.load(pickle_in)
print(get_deserialized_data_back)
Output:
{1: '6', 2: '2', 3: 'f'}

using System.Net;
using System.IO;
string url = "https://www.example.com/scriptname.php?var1=hello";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream resStream = response.GetResponseStream();
A lot of answers/comments mention components defined in other modules, or that you have to import/declare the component (that you want to use in another component) in its/their containing module.
But in the simple case where you want to use component A
from component B
when both are defined in the same module, you have to declare both components in the containing module for B
to see A
, and not only A
.
I.e. in my-module.module.ts
import { AComponent } from "./A/A.component";
import { BComponent } from "./B/B.component";
@NgModule({
declarations: [
AComponent, // This is the one that we naturally think of adding ..
BComponent, // .. but forget this one and you get a "**'AComponent'**
// is not a known element" error.
],
})
StopWatch will use the high-resolution counter
The Stopwatch measures elapsed time by counting timer ticks in the underlying timer mechanism. If the installed hardware and operating system support a high-resolution performance counter, then the Stopwatch class uses that counter to measure elapsed time. Otherwise, the Stopwatch class uses the system timer to measure elapsed time. Use the Frequency and IsHighResolution fields to determine the precision and resolution of the Stopwatch timing implementation.
If you're measuring IO then your figures will likely be impacted by external events, and I would worry so much re. exactness (as you've indicated above). Instead I'd take a range of measurements and consider the mean and distribution of those figures.
You can see the list of supported codecs in the official documentation:
Minted, whether from GitHub or CTAN, the Comprehensive TeX Archive Network, works in Overleaf, TeX Live and MiKTeX.
It requires the installation of the Python package Pygments; this is explained in the documentation in either source above. Although Pygments brands itself as a Python syntax highlighter, Minted guarantees the coverage of hundreds of other languages.
Example:
\documentclass{article}
\usepackage{minted}
\begin{document}
\begin{minted}[mathescape, linenos]{python}
# Note: $\pi=\lim_{n\to\infty}\frac{P_n}{d}$
title = "Hello World"
sum = 0
for i in range(10):
sum += i
\end{minted}
\end{document}
Output:
Ideally, every custom watch should be removed when you leave the scope.
It helps in better memory management and better app performance.
// call to $watch will return a de-register function
var listener = $scope.$watch(someVariableToWatch, function(....));
$scope.$on('$destroy', function() {
listener(); // call the de-register function on scope destroy
});
object.defineProperty
With this, you can easily access cookies
Object.defineProperty(window, "Cookies", {
get: function() {
return document.cookie.split(';').reduce(function(cookies, cookie) {
cookies[cookie.split("=")[0]] = unescape(cookie.split("=")[1]);
return cookies
}, {});
}
});
From now on you can just do:
alert( Cookies.obligations );
This will automatically update too, so if you change a cookie, the Cookies
will change too.
Either as recordset or output parameter. The latter has less overhead and I'd tend to use that rather than a single column/row recordset.
If I expected to >1 row I'd use the OUTPUT clause and a recordset
Return values would normally be used for error handling.
NumPy is slower because it casts the input to boolean values (so None and 0 becomes False and everything else becomes True).
import pandas as pd
import numpy as np
s = pd.Series([True, None, False, True])
np.logical_not(s)
gives you
0 False
1 True
2 True
3 False
dtype: object
whereas ~s would crash. In most cases tilde would be a safer choice than NumPy.
Pandas 0.25, NumPy 1.17
Remove the standard.jar
. It's apparently of old JSTL 1.0 version when the TLD URIs were without the /jsp
path. With JSTL 1.2 as available here you don't need a standard.jar
at all. Just the jstl-1.2.jar
in /WEB-INF/lib
is sufficient.
Very simple avoid using DateTime.MinValue
use System.Data.SqlTypes.SqlDateTime.MinValue
instead.
I find exporting the packages in string format only is more portable than exporting the whole conda
environment. As the previous answer already suggested:
$ conda list -e > requirements.txt
However, this requirements.txt
contains build numbers which are not portable between operating systems, e.g. between Mac
and Ubuntu
. In conda env export
we have the option --no-builds
but not with conda list -e
, so we can remove the build number by issuing the following command:
$ sed -i -E "s/^(.*\=.*)(\=.*)/\1/" requirements.txt
And recreate the environment on another computer:
conda create -n recreated_env --file requirements.txt
I have had this issue in a case where the static
function was called before it was declared. Moving the function declaration to anywhere above the call solved my problem.
Assume you stored that dictionary in a variable called values. To get id
in to a variable, do:
idValue = values['criteria'][0]['id']
If that json is in a file, do the following to load it:
import json
jsonFile = open('your_filename.json', 'r')
values = json.load(jsonFile)
jsonFile.close()
If that json is from a URL, do the following to load it:
import urllib, json
f = urllib.urlopen("http://domain/path/jsonPage")
values = json.load(f)
f.close()
To print ALL of the criteria, you could:
for criteria in values['criteria']:
for key, value in criteria.iteritems():
print key, 'is:', value
print ''
Since the purpose of these COMPILER directives are to tell the compiler NOT to include code, debug code,beta code, or perhaps code that is needed by all of your end users, except say those the advertising department, i.e. #Define AdDept you want to be able include or remove them based on your needs. Without having to change your source code if for example a non AdDept merges into the AdDept. Then all that needs to be done is to include the #AdDept directive in the compiler options properties page of an existing version of the program and do a compile and wa la! the merged program's code springs alive!.
You might also want to use a declarative for a new process that is not ready for prime time or that can not be active in the code until it's time to release it.
Anyhow, that's the way I do it.
I faced with same problem. I've used Entity Framework and thought that DB will be created automatically. Please make sure your DB exists and has a correct name.
Rank(), Dense_rank(), row_number()
These all are window functions that means they act as window over some ordered input set at first. These windows have different functionality attached to it based on the requirement. Heres the above 3 :
row_number()
Starting by row_number()
as this forms the basis of these related window functions. row_number()
as the name suggests gives a unique number to the set of rows over which its been applied. Similar to giving a serial number to each row.
Rank()
A subversion of row_number()
can be said as rank()
. Rank() is used to give same serial number to those ordered set rows which are duplicates but it still keeps the count mantained as similar to a row_number()
for all those after duplicates rank() meaning as from below eg. For data 2 row_number() =rank() meaning both just differs in the form of duplicates.
Data row_number() rank() dense_rank()
1 1 1 1
1 2 1 1
1 3 1 1
2 4 4 2
Finally,
Dense_rank() is an extended version of rank() as the name suggests its dense because as you can see from the above example rank() = dense_rank() for all data 1 but just that for data 2 it differs in the form that it mantains the order of rank() from previous rank() not the actual data
Something like this:
public static void main(String[] args) {
String N = "ABCD";
char[] array = N.toCharArray();
// and as you can see:
System.out.println(array[0]);
System.out.println(array[1]);
System.out.println(array[2]);
}
This question is about iterable objects, not about iterators. In Python, sequences are iterable too so one way to make an iterable class is to make it behave like a sequence, i.e. give it __getitem__
and __len__
methods. I have tested this on Python 2 and 3.
class CustomRange:
def __init__(self, low, high):
self.low = low
self.high = high
def __getitem__(self, item):
if item >= len(self):
raise IndexError("CustomRange index out of range")
return self.low + item
def __len__(self):
return self.high - self.low
cr = CustomRange(0, 10)
for i in cr:
print(i)
You need to wrap the forward slash to avoid cross browser issues or //commenting out.
str = 'this/that and/if';
var newstr = str.replace(/[/]/g, 'ForwardSlash');
You can use the following code snippet :
java -XX:+PrintFlagsFinal -Xms512m -Xmx1024m -Xss512k -XX:PermSize=64m -XX:MaxPermSize=128m
-version | grep -iE 'HeapSize|PermSize|ThreadStackSize'
In my pc I am getting following output :
uintx InitialHeapSize := 536870912 {product}
uintx MaxHeapSize := 1073741824 {product}
uintx PermSize := 67108864 {pd product}
uintx MaxPermSize := 134217728 {pd product}
intx ThreadStackSize := 512 {pd product}
To install or upgrade pip, download get-pip.py from the official site. Then run the following command:
sudo python get-pip.py
and it will install pip
for your python version which runs the script.
To adjust the length of the samples:
set key samplen X
(default is 4)
To adjust the vertical spacing of the samples:
set key spacing X
(default is 1.25)
and (for completeness), to adjust the fontsize:
set key font "<face>,<size>"
(default depends on the terminal)
And of course, all these can be combined into one line:
set key samplen 2 spacing .5 font ",8"
Note that you can also change the position of the key using set key at <position>
or any one of the pre-defined positions (which I'll just defer to help key
at this point)
I didn't found any particular answer to this question but i deleted the emulator and create a new one and increase the Ram size of the new emulator.Then the emulator works fine.
use sed's -i option, e.g.
sed -i bak -e s/STRING_TO_REPLACE/REPLACE_WITH/g index.html
In a much simpler way, you can do the same using
from PIL import Image
image = Image.open('image.jpg')
image.show()
Answer for 2019
The best practice is to setup two separate properties for your development/staging, and your production servers. You do not want to pollute your Analytics data with test, and setting up filters is not pleasant if you are forced to do that.
That being said, Google Analytics now has real time tracking, and if you want to track Campaigns or Transactions, the lag is around 1 minute until the data is shown on the page, as long as you select the current day.
For example, you create Site and Site Test, and each one ha UA-XXXX-Y code.
In your application logic, where you serve the analytics JavaScript, check your environment and for production use your Site UA-XXXX-Y, and for staging/development use the Site Test one.
You can have this setup until you learn the ins and outs of GA, and then remove it, or keep it if you need to make constant changes (which you will test on development/staging first).

You can check an example in Plunker over here plunker example filters
filter() {
let storeId = 1;
this.bookFilteredList = this.bookList
.filter((book: Book) => book.storeId === storeId);
this.bookList = this.bookFilteredList;
}
A little late this comment but I will leave here my results working with the library of SharePoin Online and it is very easy to use and implement in your project, just go to the NuGet administrator of .Net and Add Microsoft.SharePoint.CSOM to your project .
The following code snippet will help you connect your credentials to your SharePoint site, you can also read and download files from a specific site and folder.

Then to invoke the functions from the controller in this case MVC ASP.NET is done in the following way.
using MvcApplication.Models.Home;
using System;
using System.Web.Mvc;
namespace MvcApplication.Controllers
{
public class SharepointController : MvcBoostraBaseController
{
[HttpPost]
public ActionResult Upload(FormCollection form)
{
try
{
SharepointModel sharepointModel = new SharepointModel();
return Json(sharepointModel.UploadMultiFiles(Request, Server), JsonRequestBehavior.AllowGet);
}
catch (Exception ex)
{
return ThrowJSONError(ex);
}
}
public ActionResult Download(string ServerUrl, string RelativeUrl)
{
try
{
SharepointModel sharepointModel = new SharepointModel();
return Json(sharepointModel.DownloadFiles(), JsonRequestBehavior.AllowGet);
}
catch (Exception ex)
{
return ThrowJSONError(ex);
}
}
}
}
If you need the source code of this project you can request it to [email protected]
The simplest way I found for C++ 11 was this:
Your includes:
#include <chrono>
#include <thread>
Your code (this is an example for sleep 1000 millisecond):
std::chrono::duration<int, std::milli> timespan(1000);
std::this_thread::sleep_for(timespan);
The duration could be configured to any of the following:
std::chrono::nanoseconds duration</*signed integer type of at least 64 bits*/, std::nano>
std::chrono::microseconds duration</*signed integer type of at least 55 bits*/, std::micro>
std::chrono::milliseconds duration</*signed integer type of at least 45 bits*/, std::milli>
std::chrono::seconds duration</*signed integer type of at least 35 bits*/, std::ratio<1>>
std::chrono::minutes duration</*signed integer type of at least 29 bits*/, std::ratio<60>>
std::chrono::hours duration</*signed integer type of at least 23 bits*/, std::ratio<3600>>
sudo is used for Linux. It looks like you are running this in Windows.
Just as a heads up. I had the same problem and none of the above fixed it for me. Eventually I found out that respond.js doesn't parse CSS referenced via @import. I had the whole bootstrap.min.css
imported via @import
into my main.css
.
So make sure you don't have any CSS that contains your media queries referenced via @import.
You need to escape the dot if you want to split on a literal dot:
String extensionRemoved = filename.split("\\.")[0];
Otherwise you are splitting on the regex .
, which means "any character".
Note the double backslash needed to create a single backslash in the regex.
You're getting an ArrayIndexOutOfBoundsException
because your input string is just a dot, ie "."
, which is an edge case that produces an empty array when split on dot; split(regex)
removes all trailing blanks from the result, but since splitting a dot on a dot leaves only two blanks, after trailing blanks are removed you're left with an empty array.
To avoid getting an ArrayIndexOutOfBoundsException
for this edge case, use the overloaded version of split(regex, limit)
, which has a second parameter that is the size limit for the resulting array. When limit
is negative, the behaviour of removing trailing blanks from the resulting array is disabled:
".".split("\\.", -1) // returns an array of two blanks, ie ["", ""]
ie, when filename
is just a dot "."
, calling filename.split("\\.", -1)[0]
will return a blank, but calling filename.split("\\.")[0]
will throw an ArrayIndexOutOfBoundsException
.
For SQL server 2012 or above use EOMONTH to get the last date of month
SQL query to display end date of current month
DECLARE @currentDate DATE = GETDATE()
SELECT EOMONTH (@currentDate) AS CurrentMonthED
SQL query to display end date of Next month
DECLARE @currentDate DATE = GETDATE()
SELECT EOMONTH (@currentDate, 1 ) AS NextMonthED
Be aware that it only updates the first company it found with company id 1. For multiple
(from c in listOfCompany where c.id == 1 select c).First().Name = "Whatever Name";
For Multiple updates
from c in listOfCompany where c.id == 1 select c => {c.Name = "Whatever Name"; return c;}
select @DateCreated, DATEDIFF(WEEK, @DateCreated, GETDATE())
The jsfiddle link to where i tried out your query http://jsfiddle.net/A8Dnv/1/ its working fine @Imrul as mentioned you are using C# on server side and you dont mind that either: http://msdn.microsoft.com/en-us/library/system.text.regularexpressions.regex.escape.aspx
UPDATE:
Since this question still gets a lot of hits I'm also adding the current jQM Docs on how to disable the button:
Updated Examples:
enable enable a disabled form button
$('[type="submit"]').button('enable');
disable disable a form button
$('[type="submit"]').button('disable');
refresh update the form button
If you manipulate a form button via JavaScript, you must call the refresh method on it to update the visual styling.
$('[type="submit"]').button('refresh');
Original Post Below:
Live Example: http://jsfiddle.net/XRjh2/2/
UPDATE:
Using @naugtur example below: http://jsfiddle.net/XRjh2/16/
UPDATE #2:
Link button example:
JS
var clicked = false;
$('#myButton').click(function() {
if(clicked === false) {
$(this).addClass('ui-disabled');
clicked = true;
alert('Button is now disabled');
}
});
$('#enableButton').click(function() {
$('#myButton').removeClass('ui-disabled');
clicked = false;
});
HTML
<div data-role="page" id="home">
<div data-role="content">
<a href="#" data-role="button" id="myButton">Click button</a>
<a href="#" data-role="button" id="enableButton">Enable button</a>
</div>
</div>
NOTE: - http://jquerymobile.com/demos/1.0rc2/docs/buttons/buttons-types.html
Links styled like buttons have all the same visual options as true form-based buttons below, but there are a few important differences. Link-based buttons aren't part of the button plugin and only just use the underlying buttonMarkup plugin to generate the button styles so the form button methods (enable, disable, refresh) aren't supported. If you need to disable a link-based button (or any element), it's possible to apply the disabled class ui-disabled yourself with JavaScript to achieve the same effect.
Here you have how I usually do this kind of operations.
// We declare an empty array in wich we will store the results
$sumArray = array();
// We loop through all the key-value pairs in $myArray
foreach ($myArray as $k=>$subArray) {
// Each value is an array, we loop through it
foreach ($subArray as $id=>$value) {
// If $sumArray has not $id as key we initialize it to zero
if(!isset($sumArray[$id])){
$sumArray[$id] = 0;
}
// If the array already has a key named $id, we increment its value
$sumArray[$id]+=$value;
}
}
print_r($sumArray);
In Oracle you have three kinds of SQL statements (and additionally there are PL/SQL blocks):
Bind variables in Oracle are only allowed in some special places in DML and query statements. You are trying to use bind variables in a places where they are not allowed. Hence the error.
Build your statement without bind variables. Build the complete query string instead using string concatenation.
If you want to sanitize the input before concatenating the string, use the DBMS_ASSERT package.
Bind variables can only be used when Oracle can build a query plan without knowing the value of the variable. For DDL statements, there is no query plan. Hence bind variables are not allowed.
In DML and query statements, bind variables are only allowed, when they are used inside a tuple (regarding the underlying set theory), i.e. when the value will be compared with the value in a table or when the value will be inserted in a table. They are not allowed to change the structure of the execution plan (e.g. to change the target table or to change the number of comparisons).
To easily debug Ruby shell script, just change its first line from:
#!/usr/bin/env ruby
to:
#!/usr/bin/env ruby -rdebug
Then every time when debugger console is shown, you can choose:
c
for Continue (to the next Exception, breakpoint or line with: debugger
),n
for Next line,w
/where
to Display frame/call stack,l
to Show the current code,cat
to show catchpoints.h
for more Help.See also: Debugging with ruby-debug, Key shortcuts for ruby-debug gem.
In case the script just hangs and you need a backtrace, try using lldb
/gdb
like:
echo 'call (void)rb_backtrace()' | lldb -p $(pgrep -nf ruby)
and then check your process foreground.
Replace lldb
with gdb
if works better. Prefix with sudo
to debug non-owned process.
Based on your requirements you can also do the following without libraries like jQuery:
Add this to your head:
window.onload = function () {
document.getElementById("frmSubmit").onsubmit = function onSubmit(form) {
var isValid = true;
//validate your elems here
isValid = false;
if (!isValid) {
alert("Please check your fields!");
return false;
}
else {
//you are good to go
return true;
}
}
}
And your form may still look something like:
<form id="frmSubmit" action="/Submit">
<input type="submit" value="Submit" />
</form>
You can handle the AppDomain.UnhandledException
event
EDIT: actually, this event is probably more adequate: Application.DispatcherUnhandledException
Just goto conf folder of tomcat
open the server.xml file
Goto one of the connector node which look like the following
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
Simply change the port
save and restart tomcat
