Results.map(obj=> ({ ...obj, Active: 'false' }))
Edited to reflect comment by @adrianolsk to not mutate the original and instead return a new object for each.
Instead of using config files you can use a configuration database with a scoped systemConfig table and add all your settings there.
CREATE TABLE [dbo].[SystemConfig]
(
[Id] [int] IDENTITY(1, 1)
NOT NULL ,
[AppName] [varchar](128) NULL ,
[ScopeName] [varchar](128) NOT NULL ,
[Key] [varchar](256) NOT NULL ,
[Value] [varchar](MAX) NOT NULL ,
CONSTRAINT [PK_SystemConfig_ID] PRIMARY KEY NONCLUSTERED ( [Id] ASC )
WITH ( PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF,
IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON,
ALLOW_PAGE_LOCKS = ON ) ON [PRIMARY]
)
ON [PRIMARY]
GO
SET ANSI_PADDING OFF
GO
ALTER TABLE [dbo].[SystemConfig] ADD CONSTRAINT [DF_SystemConfig_ScopeName] DEFAULT ('SystemConfig') FOR [ScopeName]
GO
With such configuration table you can create rows like such:
Then from your your application dal(s) wrapping EF you can easily retrieve the scoped configuration.
If you are not using dal(s) and working in the wire directly with EF, you can make an Entity from the SystemConfig table and use the value depending on the application you are on.
I found another way to take a input value of a UITextField and cast it to a float:
var tempString:String?
var myFloat:Float?
@IBAction func ButtonWasClicked(_ sender: Any) {
tempString = myUITextField.text
myFloat = Float(tempString!)!
}
People wouldn't like to see a wrong commit and a revert commit to undo changes of the wrong commit. This pollutes commit history.
Here is a simple way for removing the wrong commit instead of undoing changes with a revert commit.
git checkout my-pull-request-branch
git rebase -i HEAD~n
// where n
is the number of last commits you want to include in interactive
rebase.
pick
with drop
for commits you want to discard.git push --force
The best, quickest and easiest way to resolve the comma in data issue is to use Excel to save a comma separated file after having set Windows' list separator setting to something other than a comma (such as a pipe). This will then generate a pipe (or whatever) separated file for you that you can then import. This is described here.
$('input[type=text],select', '.sys');
for looping:
$('input[type=text],select', '.sys').each(function() {
// code
});
The SuppressWarning annotation is used to suppress compiler warnings for the annotated element. Specifically, the unchecked
category allows suppression of compiler warnings generated as a result of unchecked type casts.
When you work with unsigned types, modular arithmetic (also known as "wrap around" behavior) is taking place. To understand this modular arithmetic, just have a look at these clocks:
9 + 4 = 1 (13 mod 12), so to the other direction it is: 1 - 4 = 9 (-3 mod 12). The same principle is applied while working with unsigned types. If the result type is unsigned
, then modular arithmetic takes place.
Now look at the following operations storing the result as an unsigned int
:
unsigned int five = 5, seven = 7;
unsigned int a = five - seven; // a = (-2 % 2^32) = 4294967294
int one = 1, six = 6;
unsigned int b = one - six; // b = (-5 % 2^32) = 4294967291
When you want to make sure that the result is signed
, then stored it into signed
variable or cast it to signed
. When you want to get the difference between numbers and make sure that the modular arithmetic will not be applied, then you should consider using abs()
function defined in stdlib.h
:
int c = five - seven; // c = -2
int d = abs(five - seven); // d = 2
Be very careful, especially while writing conditions, because:
if (abs(five - seven) < seven) // = if (2 < 7)
// ...
if (five - seven < -1) // = if (-2 < -1)
// ...
if (one - six < 1) // = if (-5 < 1)
// ...
if ((int)(five - seven) < 1) // = if (-2 < 1)
// ...
but
if (five - seven < 1) // = if ((unsigned int)-2 < 1) = if (4294967294 < 1)
// ...
if (one - six < five) // = if ((unsigned int)-5 < 5) = if (4294967291 < 5)
// ...
What can you do if you need to make a change to a file, but don’t know the file’s encoding? If you know the encoding is ASCII-compatible and only want to examine or modify the ASCII parts, you can open the file with the surrogateescape error handler:
with open(fname, 'r', encoding="ascii", errors="surrogateescape") as f:
data = f.read()
Use the set()
method: see doc
arraylist.set(index,newvalue);
Static memory allocation. Memory allocated will be in stack.
int a[10];
Dynamic memory allocation. Memory allocated will be in heap.
int *a = malloc(sizeof(int) * 10);
and the latter should be freed since there is no Garbage Collector(GC) in C.
free(a);
The first answer is definitely the correct answer and is what I based this lambda version off of, which is much shorter in syntax. Since Runnable has only 1 override method "run()", we can use a lambda:
this.m_someBoolFlag = false;
new android.os.Handler().postDelayed(() -> this.m_someBoolFlag = true, 300);
What does the DTD have to say?
If the XML file is for communicating with other existing software (e.g., SOAP), then check that software for what it expects.
If the XML file is for serialisation or communication with non-existing software (e.g., the one you're writing), you can define it. In which case, I'd suggest something that is both easy to parse in your language(s) of choice, and easy to read for humans. e.g., if your language (whether VB.NET or C#.NET or whatever) allows you to parse ISO dates (YYYY-MM-DD) easily, that's the one I'd suggest.
You can also check out examples in TensorFlow/skflow, which offers save
and restore
methods that can help you easily manage your models. It has parameters that you can also control how frequently you want to back up your model.
Fiddle: http://jsfiddle.net/simple/BdQvp/
You can do it like so:
I have added two buttons in the Fiddle to illustrate how you can insert or clear values in those input fields through buttons. You just capture the onClick event and call the function.
//Fires when the Document Loads, clears all input fields
$(document).ready(function() {
$('.fetch_results').find('input:text').val('');
});
//Custom Functions that you can call
function resetAllValues() {
$('.fetch_results').find('input:text').val('');
}
function addSomeValues() {
$('.fetch_results').find('input:text').val('Lala.');
}
Update:
Check out this great answer below by Beena as well for a more universal approach.
If you want to allow the user to browse for a file, you need to have an input type="file"
The closest you could get to your requirement would be to place the input type="file"
on the page and hide it. Then, trigger the click event of the input when the button is clicked:
#myFileInput {
display:none;
}
<input type="file" id="myFileInput" />
<input type="button"
onclick="document.getElementById('myFileInput').click()"
value="Select a File" />
Here's a working fiddle.
Note: I would not recommend this approach. The input type="file"
is the mechanism that users are accustomed to using for uploading a file.
Script blocks DOM load untill it's loaded and executed.
If you place scripts at the end of <body>
all of DOM has chance to load and render (page will "display" faster). <script>
will have access to all of those DOM elements.
In other hand placing it after <body>
start or above will execute script (where there's still no DOM elements).
You are including jQuery which means you can place it wherever you wish and use .ready()
Try adding JRE System Library in the build path of your project.
One other alternative is to use function name in #if
. The #if
will detect if the parameter is function and if it is then it will call it and use its return for truthyness check. Below myFunction gets current context as this
.
{{#if myFunction}}
I'm Happy!
{{/if}}
Under Project->Properties->Debug, you should see a box for Command line arguments (This is in C# 2010, but it should basically be the same place)
In SSMS, "Query" menu item... "Results to"... "Results to File"
Shortcut = CTRL+shift+F
You can set it globally too
"Tools"... "Options"... "Query Results"... "SQL Server".. "Default destination" drop down
Edit: after comment
In SSMS, "Query" menu item... "SQLCMD" mode
This allows you to run "command line" like actions.
A quick test in my SSMS 2008

SELECT * FROM sys.objects
Edit, Sep 2012

From SQL Server point of view:
Clustering will give you an active - passive configuration. Meaning in a 2 node cluster, one of them will be the active (serving) and the other one will be passive (waiting to take over when the active node fails). It's a high availability from hardware point of view.
You can have an active-active cluster, but it will require multiple instances of SQL Server running on each node. (i.e. Instance 1 on Node A failing over to Instance 2 on Node B, and instance 1 on Node B failing over to instance 2 on Node A).
Load balancing (at least from SQL Server point of view) does not exists (at least in the same sense of web server load balancing). You can't balance load that way. However, you can split your application to run on some database on server 1 and also run on some database on server 2, etc. This is the primary mean of "load balancing" in SQL world.
geonames is nice. an export tool based on geonames:
https://github.com/yosoyadri/GeoNames-XML-Builder
there's also the excellent pycountry module:
You can track the value of each child input
by creating a separate InputField
component that manages the value of a single input
. For example the InputField
could be:
var InputField = React.createClass({
getInitialState: function () {
return({text: this.props.text})
},
onChangeHandler: function (event) {
this.setState({text: event.target.value})
},
render: function () {
return (<input onChange={this.onChangeHandler} value={this.state.text} />)
}
})
Now the value of each input
can be tracked within a separate instance of this InputField
component without creating separate values in the parent's state to monitor each child component.
It could have something to do with your styles. In my case, I am using a link within the parent "item" div, so I had to change my stylesheet to say the following:
.carousel .item a > img {
display: block;
line-height: 1;
}
under the preexisting boostrap code:
.carousel .item > img {
display: block;
line-height: 1;
}
and my image looks like:
<div class="active item" id="2"><a href="http://epdining.com/eats.php?place=TestRestaurant1"><img src="rimages/2.jpg"></a><div class="carousel-caption"><p>This restaurant is featured blah blah blah blah blah.</p></div></div>
Change key in Project > Build Setting "typecheck calls to printf/scanf : NO"
Explanation : [How it works]
Check calls to printf and scanf, etc., to make sure that the arguments supplied have types appropriate to the format string specified, and that the conversions specified in the format string make sense.
Hope it work
Other warning
objective c implicit conversion loses integer precision 'NSUInteger' (aka 'unsigned long') to 'int

Find if the given number is a power of 2.
#include <math.h>
int main(void)
{
int n,logval,powval;
printf("Enter a number to find whether it is s power of 2\n");
scanf("%d",&n);
logval=log(n)/log(2);
powval=pow(2,logval);
if(powval==n)
printf("The number is a power of 2");
else
printf("The number is not a power of 2");
getch();
return 0;
}
My approach:
define a default constraint on the ModDate
column with a value of GETDATE()
- this handles the INSERT
case
have a AFTER UPDATE
trigger to update the ModDate
column
Something like:
CREATE TRIGGER trg_UpdateTimeEntry
ON dbo.TimeEntry
AFTER UPDATE
AS
UPDATE dbo.TimeEntry
SET ModDate = GETDATE()
WHERE ID IN (SELECT DISTINCT ID FROM Inserted)
What worked for me was to rename the project by removing the special characters.
Example: "project_marketplace" to "projectmarketplace"
In this case, I redid the project with react-native init and copied the src and package.json folder.
Write below code in script and also add jQuery library
var getElement = document.getElementById('myID');
if (document.activeElement === getElement) {
$(document).keydown(function(event) {
if (event.which === 40) {
console.log('keydown pressed')
}
});
}
Thank you...
After you correct the possible dmp file problem, this is a way to ensure that the schema is remapped and imported appropriately. This will also ensure that the tablespace will change also, if needed:
impdp system/<password> SCHEMAS=user1 remap_schema=user1:user2 \
remap_tablespace=user1:user2 directory=EXPORTDIR \
dumpfile=user1.dmp logfile=E:\Data\user1.log
EXPORTDIR must be defined in oracle as a directory as the system user
create or replace directory EXPORTDIR as 'E:\Data';
grant read, write on directory EXPORTDIR to user2;
Compare getApplication()
and getApplicationContext()
.
getApplication
returns an Application
object which will allow you to manage your global application state and respond to some device situations such as onLowMemory()
and onConfigurationChanged()
.
getApplicationContext
returns the global application context - the difference from other contexts is that for example, an activity context may be destroyed (or otherwise made unavailable) by Android when your activity ends. The Application context remains available all the while your Application object exists (which is not tied to a specific Activity
) so you can use this for things like Notifications that require a context that will be available for longer periods and independent of transient UI objects.
I guess it depends on what your code is doing whether these may or may not be the same - though in normal use, I'd expect them to be different.
f = ... # file-like object, i.e. supporting read(size) function and
# returning empty string '' when there is nothing to read
def chunked(file, chunk_size):
return iter(lambda: file.read(chunk_size), '')
for data in chunked(f, 65536):
# process the data
UPDATE: The approach is best explained in https://stackoverflow.com/a/4566523/38592
You will find the application folder at:
/data/data/"your package name"
you can access this folder using the DDMS for your Emulator. you can't access this location on a real device unless you have a rooted device.
I had the same problem - I changed my text encoding to UTF-16 on my index file and my css file would show up blank when I'd try to load the page in the browser. I figured out by much trial and error that your html and css files have to have the same encoding! I don't know if this would work for you but it did for me.
Simply:
/^([^0-9]*)$/
That pattern matches any number of characters that is not 0
through 9
.
I recommend checking out http://regexpal.com/. It will let you easily test out a regex.
I really liked Marc's answer too - I needed a set of different colored ULs and obviously it would be easier just to use a class. Here is what I used for orange, for example:
ul.orange {
list-style: none;
padding: 0px;
}
ul.orange > li:before {
content: '\25CF ';
font-size: 15px;
color: #F00;
margin-right: 10px;
padding: 0px;
line-height: 15px;
}
Plus, I found that the hex code I used for "content:" was different than Marc's (that hex circle seemed to sit a bit too high). The one I used seems to sit perfectly in the middle. I also found several other shapes (squares, triangles, circles, etc.) right here
Use this function. It works like a charm. replace "|" with the char to explode/split and the values 1,2,3,etc are based on the number of entries in the data-set: Value_ONE|Value_TWO|Value_THREE.

SUBSTRING_INDEX(SUBSTRING_INDEX(`tblNAME`.`tblFIELD`, '|', 2), '|', -1) AS GPM,

I hope this helps.
Scott Meyers has this to say in Effective Modern C++
The existence of
std::unique_ptr
for arrays should be of only intellectual interest to you, becausestd::array
,std::vector
,std::string
are virtually always better data structure choices than raw arrays. About the only situation I can conceive of when astd::unique_ptr<T[]>
would make sense would be when you're using a C-like API that returns a raw pointer to a heap array that you assume ownership of.
I think that Charles Salvia's answer is relevant though: that std::unique_ptr<T[]>
is the only way to initialise an empty array whose size is not known at compile time. What would Scott Meyers have to say about this motivation for using std::unique_ptr<T[]>
?
yield(): yield method is used to pause the execution of currently running process so that other waiting thread with the same priority will get CPU to execute.Threads with lower priority will not be executed on yield. if there is no waiting thread then this thread will start its execution.
join(): join method stops currently executing thread and wait for another to complete on which in calls the join method after that it will resume its own execution.
For detailed explanation, see this link.
Put a progress bar and the webview inside a relativelayout and set the properties for the progress bar as follows,
and then in onPageStarted() of the webclient make the progress bar visible so that it shows the progressbar when you have clicked on a link. In onPageFinished() make the progress bar visiblility as GONE so that it disappears when the page has finished loading... This will work fine for your scenario. Hope this helps...
As noted in several blogs, strtotime() solves the "+1 month" ("next month") issue on days that do not exist in the subsequent month differently than other implementations like for example MySQL.
$dt = date("Y-m-d");
echo date( "Y-m-d", strtotime( "$dt +1 day" ) ); // PHP: 2009-03-04
echo date( "Y-m-d", strtotime( "2009-01-31 +2 month" ) ); // PHP: 2009-03-31
Here is some HTML and CSS code that would solve your issue:
CSS
.ImageBorder
{
border-width: 1px;
border-color: Black;
}
HTML
<img src="MyImage.gif" class="ImageBorder" />
As the gentlemen described the difference with variant details.
I would like to recommend the use of the Apache Commons io api, class FilenameUtils
when dealing with files in a program with the possibility of deploying on multiple OSs.
Update in 2019:
This is now officially supported in Visual Studio 2019 Preview 2 for .Net Core 3.0 or higher. Of course, you may have to put some thoughts in potential risks of using a Preview version of IDE. I imagine in the near future this will be included in the official Visual Studio.
Fortunately, data breakpoints are no longer a C++ exclusive because they are now available for .NET Core (3.0 or higher) in Visual Studio 2019 Preview 2!
This is how I fixed it in my project.
It was working, and when a colleague submitted his changes, I received the "Unable to load DLL 'SQLite.Interop.dll'" exception.
Diffing the project's .csproj file, this was in the NON-WORKING version:
<ItemGroup>
<Content Include="x64\SQLite.Interop.dll" />
<Content Include="x86\SQLite.Interop.dll" />
</ItemGroup>
And this is what the WORKING version had:
<ItemGroup>
<Content Include="x64\SQLite.Interop.dll">
<CopyToOutputDirectory>Always</CopyToOutputDirectory>
</Content>
<Content Include="x86\SQLite.Interop.dll">
<CopyToOutputDirectory>Always</CopyToOutputDirectory>
</Content>
</ItemGroup>
After reverting back, I didn't receive the exception. The DLL files were dumped in the appropriate Debug\x64 (etc) folders.
Played with Boo's approach, however don't like the fact that user got kicked off only once another digest is run, which means user stays logged in until he tries to do something within the page, and then immediatelly kicked off.
I am trying to force the logoff using interval which checks every minute if last action time was more than 30 minutes ago. I hooked it on $routeChangeStart, but could be also hooked on $rootScope.$watch as in Boo's example.
app.run(function($rootScope, $location, $interval) {
var lastDigestRun = Date.now();
var idleCheck = $interval(function() {
var now = Date.now();
if (now - lastDigestRun > 30*60*1000) {
// logout
}
}, 60*1000);
$rootScope.$on('$routeChangeStart', function(evt) {
lastDigestRun = Date.now();
});
});
The other answers lack a concrete example, so here it goes:
Given the following People table:
FirstName | LastName | YearOfBirth
----------------------------------------
Thomas | Alva Edison | 1847
Benjamin | Franklin | 1706
Thomas | More | 1478
Thomas | Jefferson | 1826
If you execute the query below:
SELECT * FROM People ORDER BY FirstName DESC, YearOfBirth ASC
The result set will look like this:
FirstName | LastName | YearOfBirth
----------------------------------------
Thomas | More | 1478
Thomas | Jefferson | 1826
Thomas | Alva Edison | 1847
Benjamin | Franklin | 1706
You can use primitive collections available in Eclipse Collections. Eclipse Collections has List
, Set
, Bag
and Map
for all primitives. The elements in the primitive collections are maintained as primitives and no boxing takes place.
You can initialize a IntList like this:
MutableIntList ints = IntLists.mutable.empty();
You can convert from a List<Integer>
to IntList
like this:
List<Integer> integers = new ArrayList<>();
MutableIntList ints = ListAdapter.adapt(integers).collectInt(each -> each);
Note: I am a contributor to Eclipse Collections.
According to:
Fixing Node Mysql "Error: Cannot enqueue Handshake after invoking quit.":
http://codetheory.in/fixing-node-mysql-error-cannot-enqueue-handshake-after-invoking-quit/
TL;DR You need to establish a new connection by calling the
createConnection
method after every disconnection.
and
Note: If you're serving web requests, then you shouldn't be ending connections on every request. Just create a connection on server startup and use the connection/client object to query all the time. You can listen on the error event to handle server disconnection and for reconnecting purposes. Full code here.
From:
Readme.md - Server disconnects:
It says:
Server disconnects
You may lose the connection to a MySQL server due to network problems, the server timing you out, or the server crashing. All of these events are considered fatal errors, and will have the
err.code = 'PROTOCOL_CONNECTION_LOST'
. See the Error Handling section for more information.The best way to handle such unexpected disconnects is shown below:
function handleDisconnect(connection) { connection.on('error', function(err) { if (!err.fatal) { return; } if (err.code !== 'PROTOCOL_CONNECTION_LOST') { throw err; } console.log('Re-connecting lost connection: ' + err.stack); connection = mysql.createConnection(connection.config); handleDisconnect(connection); connection.connect(); }); } handleDisconnect(connection);
As you can see in the example above, re-connecting a connection is done by establishing a new connection. Once terminated, an existing connection object cannot be re-connected by design.
With Pool, disconnected connections will be removed from the pool freeing up space for a new connection to be created on the next getConnection call.
I have tweaked the function such that every time a connection is needed, an initializer function adds the handlers automatically:
function initializeConnection(config) {
function addDisconnectHandler(connection) {
connection.on("error", function (error) {
if (error instanceof Error) {
if (error.code === "PROTOCOL_CONNECTION_LOST") {
console.error(error.stack);
console.log("Lost connection. Reconnecting...");
initializeConnection(connection.config);
} else if (error.fatal) {
throw error;
}
}
});
}
var connection = mysql.createConnection(config);
// Add handlers.
addDisconnectHandler(connection);
connection.connect();
return connection;
}
Initializing a connection:
var connection = initializeConnection({
host: "localhost",
user: "user",
password: "password"
});
Minor suggestion: This may not apply to everyone but I did run into a minor issue relating to scope. If the OP feels this edit was unnecessary then he/she can choose to remove it. For me, I had to change a line in initializeConnection
, which was var connection = mysql.createConnection(config);
to simply just
connection = mysql.createConnection(config);
The reason being that if connection
is a global variable in your program, then the issue before was that you were making a new connection
variable when handling an error signal. But in my nodejs code, I kept using the same global connection
variable to run queries on, so the new connection
would be lost in the local scope of the initalizeConnection
method. But in the modification, it ensures that the global connection
variable is reset This may be relevant if you're experiencing an issue known as
Cannot enqueue Query after fatal error
after trying to perform a query after losing connection and then successfully reconnecting. This may have been a typo by the OP, but I just wanted to clarify.
Yes, with set_index you can make Locality
your row index.
data.set_index('Locality', inplace=True)
If inplace=True
is not provided, set_index
returns the modified dataframe as a result.
Example:
> import pandas as pd
> df = pd.DataFrame([['ABBOTSFORD', 427000, 448000],
['ABERFELDIE', 534000, 600000]],
columns=['Locality', 2005, 2006])
> df
Locality 2005 2006
0 ABBOTSFORD 427000 448000
1 ABERFELDIE 534000 600000
> df.set_index('Locality', inplace=True)
> df
2005 2006
Locality
ABBOTSFORD 427000 448000
ABERFELDIE 534000 600000
> df.loc['ABBOTSFORD']
2005 427000
2006 448000
Name: ABBOTSFORD, dtype: int64
> df.loc['ABBOTSFORD'][2005]
427000
> df.loc['ABBOTSFORD'].values
array([427000, 448000])
> df.loc['ABBOTSFORD'].tolist()
[427000, 448000]
I had this error because I had an index.ts
file in the root of my app that was exporting my app.component.ts
. So I thought I could do the following:
import { AppComponent } from './';
This worked and gave me no red squiggly lines and even intellisense brings up AppComponent when you start typing it. But come to find out it was causing this error. After I changed it to:
import { AppComponent } from './app.component';
The error went away.
Another option would be to add engine='python'
to the command pandas.read_csv(filename, sep='\t', engine='python')
If I use exit()
in a code and run it in the shell, it shows a message asking whether I want to kill the program or not. It's really disturbing.
See here
But sys.exit()
is better in this case. It closes the program and doesn't create any dialogue box.
The most likely explanation is that either a file called 'pandas.py' is in the same directory as your script, or that another variable called 'pd' is used in your program.
function getStringReminder(str, substr, occ) {
let index = str.indexOf(substr);

break;
}
index = str.indexOf(substr, index + 1)
i++;
}
return preIndex;
}
console.log(getStringReminder('bcdefgbcdbcd', 'bcd', 3));

It seems that this is a very long running problem, with a lot of differing explanations. I took the advice of the two most common presented answers here, but neither one of these solved my problems of the VM claiming it couldn't afford the bytes to perform the decoding part of the process. After some digging I learned that the real problem here is the decoding process taking away from the NATIVE heap.
See here: BitmapFactory OOM driving me nuts
That lead me to another discussion thread where I found a couple more solutions to this problem. One is to callSystem.gc();
manually after your image is displayed. But that actually makes your app use MORE memory, in an effort to reduce the native heap. The better solution as of the release of 2.0 (Donut) is to use the BitmapFactory option "inPurgeable". So I simply added o2.inPurgeable=true;
just after o2.inSampleSize=scale;
.
More on that topic here: Is the limit of memory heap only 6M?
Now, having said all of this, I am a complete dunce with Java and Android too. So if you think this is a terrible way to solve this problem, you are probably right. ;-) But this has worked wonders for me, and I have found it impossible to run the VM out of heap cache now. The only drawback I can find is that you are trashing your cached drawn image. Which means if you go RIGHT back to that image, you are redrawing it each and every time. In the case of how my application works, that is not really a problem. Your mileage may vary.
To add on this, today you are able to use pandas to import json:
https://pandas.pydata.org/pandas-docs/stable/generated/pandas.read_json.html
You may want to do a careful use of the orient parameter.
if you have existing project and you would like to add remote repository url then you need to do following command
git init
if you would like to add readme.md file then you can create it and add it using below command.
git add README.md
make your first commit using below command
git commit -m "first commit"
Now you completed all local repository process, now how you add remote repository url ? check below command this is for ssh url, you can change it for https.
git remote add origin [email protected]:user-name/repository-name.git
How you push your first commit see below command :
git push -u origin master
Using SelectionRange
you will get the Start
and End
date.
private void monthCalendar1_DateSelected(object sender, DateRangeEventArgs e)
{
var startDate = monthCalendar1.SelectionRange.Start.ToString("dd MMM yyyy");
var endDate = monthCalendar1.SelectionRange.End.ToString("dd MMM yyyy");
}
If you want to update the maximum number of days that can be selected, then set MaxSelectionCount
property. The default is 7.
// Only allow 21 days to be selected at the same time.
monthCalendar1.MaxSelectionCount = 21;
Just academic version without having clause:
select *
from (
select gid, count(*) as tmpcount from gd group by gid
) as tmp
where tmpcount > 10;
A more simple solution is as follows. Just check True/False with pandas .duplicated()
method and then take sum. Please also see pandas.Series.duplicated — pandas 0.24.1 documentation
import pandas as pd
def has_duplicated(l):
return pd.Series(l).duplicated().sum() > 0
print(has_duplicated(['one', 'two', 'one']))
# True
print(has_duplicated(['one', 'two', 'three']))
# False
Use the DateTime.ToUniversalTime
method.
if you are using ajax in your page that require script manager Page.ClientScript
will not work,
Try this and it would do the work:
ScriptManager.RegisterClientScriptBlock(this, GetType(),
"alertMessage", @"alert('your Message ')", true);
Esc to make sure you exit insert mode, then :wq
(colon w q) or ZZ
(shift-Z shift-Z).
To resolve this problem in the query without changing either database, you can cast the expressions on other side of the "=" sign with
COLLATE SQL_Latin1_General_CP1_CI_AS
as suggested here.
There is actually a reason behind why all these are messed up. A little more digging deeper is done in this thread and might be helpful to understand the reason why "\\" behaves like this.
Instead of taking the HttpServletRequest
object in every method, keep in controllers' context by auto-wiring via the constructor. Then you can access from all methods of the controller.
public class OAuth2ClientController {
@Autowired
private OAuth2ClientService oAuth2ClientService;
private HttpServletRequest request;
@Autowired
public OAuth2ClientController(HttpServletRequest request) {
this.request = request;
}
@RequestMapping(method = RequestMethod.POST)
public ResponseEntity<String> createClient(@RequestBody OAuth2Client client) {
System.out.println(request.getRequestURI());
System.out.println(request.getHeader("Content-Type"));
return ResponseEntity.ok();
}
}
You can use the getGraphics method of the component on which you would like to draw. This in turn should allow you to draw lines and make other things which are available through the Graphics class
if the database is maintained by you then simply create a new database and import the data from the old one. the collation problem is solved!!!!!
the am giving you is the code for trigger for INSERT, UPDATE and DELETE this works fine on Microsoft SQL SERVER 2008 and onwards database i am using is Northwind
/* comment section first create a table to keep track of Insert, Delete, Update
create table Emp_Audit(
EmpID int,
Activity varchar(20),
DoneBy varchar(50),
Date_Time datetime NOT NULL DEFAULT GETDATE()
);
select * from Emp_Audit*/
create trigger Employee_trigger
on Employees
after UPDATE, INSERT, DELETE
as
declare @EmpID int,@user varchar(20), @activity varchar(20);
if exists(SELECT * from inserted) and exists (SELECT * from deleted)
begin
SET @activity = 'UPDATE';
SET @user = SYSTEM_USER;
SELECT @EmpID = EmployeeID from inserted i;
INSERT into Emp_Audit(EmpID,Activity, DoneBy) values (@EmpID,@activity,@user);
end
If exists (Select * from inserted) and not exists(Select * from deleted)
begin
SET @activity = 'INSERT';
SET @user = SYSTEM_USER;
SELECT @EmpID = EmployeeID from inserted i;
INSERT into Emp_Audit(EmpID,Activity, DoneBy) values(@EmpID,@activity,@user);
end
If exists(select * from deleted) and not exists(Select * from inserted)
begin
SET @activity = 'DELETE';
SET @user = SYSTEM_USER;
SELECT @EmpID = EmployeeID from deleted i;
INSERT into Emp_Audit(EmpID,Activity, DoneBy) values(@EmpID,@activity,@user);
end
I found one good thing about using bind is that you get to know the trigger event: something like: "You clicked with event = [ButtonPress event state=Mod1 num=1 x=43 y=20]" due to the code below:
self.submit.bind('<Button-1>', self.parse)
def parse(self, trigger_event):
print("You clicked with event = {}".format(trigger_event))
Comparing the following two ways of coding a button click:
btn = Button(root, text="Click me to submit", command=(lambda: reply(ent.get())))
btn = Button(root, text="Click me to submit")
btn.bind('<Button-1>', (lambda event: reply(ent.get(), e=event)))
def reply(name, e = None):
messagebox.showinfo(title="Reply", message = "Hello {0}!\nevent = {1}".format(name, e))
The first one is using the command function which doesn't take an argument, so no event pass-in is possible. The second one is a bind function which can take an event pass-in and print something like "Hello Charles! event = [ButtonPress event state=Mod1 num=1 x=68 y=12]"
We can left click, middle click or right click a mouse which corresponds to the event number of 1, 2 and 3, respectively. Code:
btn = Button(root, text="Click me to submit")
buttonClicks = ["<Button-1>", "<Button-2>", "<Button-3>"]
for bc in buttonClicks:
btn.bind(bc, lambda e : print("Button clicked with event = {}".format(e.num)))
Output:
Button clicked with event = 1
Button clicked with event = 2
Button clicked with event = 3
You have to write this code instead of return View(); :
return RedirectToAction("ActionName", "ControllerName");
Based on the instructions at the link below, do the following.
In VBA insert a new module and paste in this code:
Public Function UserName()
UserName = Environ$("UserName")
End Function
Call the function using the formula:

Based on instructions at:
Use following formula:
=CONCATENATE(LOWER(MID(A1,1,1)),LOWER( B1))
for
Josh Smith = jsmith
note that A1 contains name and B1 contains surname
Maybe this may help you as well. I was having some trouble getting my head wrapped around how socket.io worked, so I tried to boil an example down as much as I could.
I adapted this example from the example posted here: http://socket.io/get-started/chat/
First, start in an empty directory, and create a very simple file called package.json Place the following in it.
{
"dependencies": {}
}
Next, on the command line, use npm to install the dependencies we need for this example
$ npm install --save express socket.io
This may take a few minutes depending on the speed of your network connection / CPU / etc. To check that everything went as planned, you can look at the package.json file again.
$ cat package.json
{
"dependencies": {
"express": "~4.9.8",
"socket.io": "~1.1.0"
}
}
Create a file called server.js This will obviously be our server run by node. Place the following code into it:
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
app.get('/', function(req, res){
//send the index.html file for all requests
res.sendFile(__dirname + '/index.html');
});
http.listen(3001, function(){
console.log('listening on *:3001');
});
//for testing, we're just going to send data to the client every second
setInterval( function() {
/*
our message we want to send to the client: in this case it's just a random
number that we generate on the server
*/
var msg = Math.random();
io.emit('message', msg);
console.log (msg);
}, 1000);
Create the last file called index.html and place the following code into it.
<html>
<head></head>
<body>
<div id="message"></div>
<script src="/socket.io/socket.io.js"></script>
<script>
var socket = io();
socket.on('message', function(msg){
console.log(msg);
document.getElementById("message").innerHTML = msg;
});
</script>
</body>
</html>
You can now test this very simple example and see some output similar to the following:
$ node server.js
listening on *:3001
0.9575486415997148
0.7801907607354224
0.665313188219443
0.8101786421611905
0.890920243691653
If you open up a web browser, and point it to the hostname you're running the node process on, you should see the same numbers appear in your browser, along with any other connected browser looking at that same page.
This worked for me, I was able to pull and push into my remote repo.

if you use 'Month' in to_char it right pads to 9 characters; you have to use the abbreviated 'MON', or to_char then trim and concatenate it to avoid this. See, http://www.techonthenet.com/oracle/functions/to_char.php
select trim(to_char(date_field, 'month')) || ' ' || to_char(date_field,'dd, yyyy')
from ...
or
select to_char(date_field,'mon dd, yyyy')
from ...
if you state a.redLink{color:red;}
then to keep this on hover and such add a.redLink:hover{color:red;}
This will make sure no other hover states will change the color of your links
The following shows how to set in Java a proxy with proxy user and proxy password from the command line, which is a very common case. You should not save passwords and hosts in the code, as a rule in the first place.
Passing the system properties in command line with -D and setting them in the code with System.setProperty("name", "value") is equivalent.
But note this
Example that works:
C:\temp>java -Dhttps.proxyHost=host -Dhttps.proxyPort=port -Dhttps.proxyUser=user -Dhttps.proxyPassword="password" -Djavax.net.ssl.trustStore=c:/cacerts -Djavax.net.ssl.trustStorePassword=changeit com.andreas.JavaNetHttpConnection
But the following does not work:
C:\temp>java com.andreas.JavaNetHttpConnection -Dhttps.proxyHost=host -Dhttps.proxyPort=port -Dhttps=proxyUser=user -Dhttps.proxyPassword="password" -Djavax.net.ssl.trustStore=c:/cacerts -Djavax.net.ssl.trustStorePassword=changeit
The only difference is the position of the system properties! (before and after the class)
If you have special characters in password, you are allowed to put it in quotes "@MyPass123%", like in the above example.
If you access an HTTPS service, you have to use https.proxyHost
, https.proxyPort
etc.
If you access an HTTP service, you have to use http.proxyHost
, http.proxyPort
etc.
Probably this information will help. I was on Ubuntu 18.04 and when I tried to install Krita, using the ppa method, I got this error:
This application failed to start because it could not find or load the Qt platform plugin "xcb" in "".
Available platform plugins are: linuxfb, minimal, minimalegl, offscreen, wayland-egl, wayland, xcb.
Reinstalling the application may fix this problem.
Aborted
I tried all the solutions that I found in this thread and other webs without any success.
Finally, I found a post where the author mention that is possible to activate the debugging tool of qt5 using this simple command:
export QT_DEBUG_PLUGINS=1
After adding this command I run again krita I got the same error, however this time I knew the cause of that error.
libxcb-xinerama.so.0: cannot open shared object file: No such file or directory.
This error prevents to the "xcb" to load properly. So, the solution will be install the `libxcb-xinerama.so.0" right? However, when I run the command:
sudo apt install libxcb-xinerama
The lib was already installed. Now what Teo? Well, then I used an old trick :) Yeah, that one --reinstall
sudo apt install --reinstall libxcb-xinerama
TLDR: This last command solved my problem.
You can use the toolbarHeight property of Appbar, it does exactly what you want.
This is mentioned in the Missing Data section of the docs:
NA groups in GroupBy are automatically excluded. This behavior is consistent with R
One workaround is to use a placeholder before doing the groupby (e.g. -1):
In [11]: df.fillna(-1)
Out[11]:
a b
0 1 4
1 2 -1
2 3 6
In [12]: df.fillna(-1).groupby('b').sum()
Out[12]:
a
b
-1 2
4 1
6 3
That said, this feels pretty awful hack... perhaps there should be an option to include NaN in groupby (see this github issue - which uses the same placeholder hack).
However, as described in another answer, "from pandas 1.1 you have better control over this behavior, NA values are now allowed in the grouper using dropna=False"

For converting categorical data in column C of dataset data, we need to do the following:
from sklearn.preprocessing import LabelEncoder
labelencoder= LabelEncoder() #initializing an object of class LabelEncoder
data['C'] = labelencoder.fit_transform(data['C']) #fitting and transforming the desired categorical column.
Updated Feb 2018: OpenBrace Limited has closed down, and its ObMimic product is no longer supported.

}
}
Notes:
Each "mimic" has a "mimicState" object for its logical state. This provides a clear distinction between the Servlet API methods and the configuration and inspection of the mimic's internal state.
You might be surprised that the check of Content-Type includes "charset=ISO-8859-1". However, for the given "doPost" code this is as per the Servlet API Javadoc, and the HttpServletResponse's own getContentType method, and the actual Content-Type header produced on e.g. Glassfish 3. You might not realise this if using normal mock objects and your own expectations of the API's behaviour. In this case it probably doesn't matter, but in more complex cases this is the sort of unanticipated API behaviour that can make a bit of a mockery of mocks!
I've used response.getMimicState().getContentType()
as the simplest way to check Content-Type and illustrate the above point, but you could indeed check for "text/html" on its own if you wanted (using response.getMimicState().getContentTypeMimeType()
). Checking the Content-Type header the same way as for the Cache-Control header also works.
For this example the response content is checked as character data (with this using the Writer's encoding). We could also check that the response's Writer was used rather than its OutputStream (using response.getMimicState().isWritingCharacterContent()
), but I've taken it that we're only concerned with the resulting output, and don't care what API calls produced it (though that could be checked too...). It's also possible to retrieve the response's body content as bytes, examine the detailed state of the Writer/OutputStream etc.
There are full details of ObMimic and a free download at the OpenBrace website. Or you can contact me if you have any questions (contact details are on the website).
The most recent and in my opinion preferred approach is the f-string
:
''.join(f'{i:02x}' for i in [1, 15, 255])
The old format style was the %
-syntax:
['%02x'%i for i in [1, 15, 255]]
The more modern approach is the .format
method:
['{:02x}'.format(i) for i in [1, 15, 255]]
More recently, from python 3.6 upwards we were treated to the f-string
syntax:
[f'{i:02x}' for i in [1, 15, 255]]
Note that the f'{i:02x}'
works as follows.
:
is the input or variable to format. x
indicates that the string should be hex. f'{100:02x}'
is '64'
and f'{100:02d}'
is '1001'
.02
indicates that the string should be left-filled with 0
's to length 2
. f'{100:02x}'
is '64'
and f'{100:30x}'
is ' 64'
.two ways:
x = [0] * 10
x = [0 for i in xrange(10)]
Edit: replaced range
by xrange
to avoid creating another list.
Also: as many others have noted including Pi and Ben James, this creates a list
, not a Python array. While a list is in many cases sufficient and easy enough, for performance critical uses (e.g. when duplicated in thousands of objects) you could look into python arrays. Look up the array
module, as explained in the other answers in this thread.
All required parameters must be placed before any default arguments. Simply because they are mandatory, whereas default arguments are not. Syntactically, it would be impossible for the interpreter to decide which values match which arguments if mixed modes were allowed. A SyntaxError
is raised if the arguments are not given in the correct order:
Let us take a look at keyword arguments, using your function.
def fun1(a="who is you", b="True", x, y):
... print a,b,x,y
Suppose its allowed to declare function as above, Then with the above declarations, we can make the following (regular) positional or keyword argument calls:
func1("ok a", "ok b", 1) # Is 1 assigned to x or ?
func1(1) # Is 1 assigned to a or ?
func1(1, 2) # ?
How you will suggest the assignment of variables in the function call, how default arguments are going to be used along with keyword arguments.
>>> def fun1(x, y, a="who is you", b="True"):
... print a,b,x,y
...
Reference O'Reilly - Core-Python
Where as this function make use of the default arguments syntactically correct for above function calls.
Keyword arguments calling prove useful for being able to provide for out-of-order positional arguments, but, coupled with default arguments, they can also be used to "skip over" missing arguments as well.
Or, for less code, inside your click you place:
setTimeout(function(){
$('#DIV_ID').scrollTop(0);
}, 500);
you can try this without any java script you can do that just by using CSS
img:active,
img:focus,
img:hover{
border: 10px solid red !important
}
of if your case is to add any other css class by clicking you can use query selector like
<img id="image1" ng-click="changeClass(id)" >
<img id="image2" ng-click="changeClass(id)" >
<img id="image3" ng-click="changeClass(id)" >
<img id="image3" ng-click="changeClass(id)" >
in controller first search for any image with red border and remove it then by passing the image id add the border class to that image
$scope.changeClass = function(id){
angular.element(document.querySelector('.some-class').removeClass('.some-class');
angular.element(document.querySelector(id)).addClass('.some-class');
}
It might be helpful to rely on the Workbook factory to instantiate the workbook object since the factory method will do the detection of xls or xlsx for you. Reference: http://apache-poi.1045710.n5.nabble.com/How-to-check-for-valid-excel-files-using-POI-without-checking-the-file-extension-td2341055.html
IWorkbook workbook = WorkbookFactory.Create(inputStream);
If you're not sure of the Sheet's name but you are sure of the index (0 based), you can grab the sheet like this:
ISheet sheet = workbook.GetSheetAt(sheetIndex);
You can then iterate through the rows using code supplied by the accepted answer from mj82
Try looking at Double.TryParse() if you are using .NET 1.1/2.0/3.0/3.5/4.0/4.5

This is an older post, but I do have a better solution. Create a form containing all of your post values as hidden fields and give the form a name such as:
<form name="RefreshForm" method="post" action="http://yoursite/yourscript">
<input type="hidden" name="postVariable" value="PostData">
</form>
Then all you need to do in your setTimeout
is RefreshForm.submit();
Cheers!
CURRENT_DATE
and CURRENT_TIMESTAMP
return the current date and time in the session time zone.
SYSDATE
and SYSTIMESTAMP
return the system date and time - that is, of the system on which the database resides.
If your client session isn't in the same timezone as the server the database is on (or says it isn't anyway, via your NLS settings), mixing the SYS*
and CURRENT_*
functions will return different values. They are all correct, they just represent different things. It looks like your server is (or thinks it is) in a +4:00 timezone, while your client session is in a +4:30 timezone.
You might also see small differences in the time if the clocks aren't synchronised, which doesn't seem to be an issue here.
platform.architecture()
notes say:
Note: On Mac OS X (and perhaps other platforms), executable files may be universal files containing multiple architectures.
To get at the “64-bitness” of the current interpreter, it is more reliable to query the sys.maxsize attribute:
import sys
is_64bits = sys.maxsize > 2**32
This approach also works with same hierarchy of Controller files:
$printReport = new PrintReportController;
$prinReport->getPrintReport();
Try using this code for v3:
gMap = new google.maps.Map(document.getElementById('map'));
gMap.setZoom(13); // This will trigger a zoom_changed on the map
gMap.setCenter(new google.maps.LatLng(37.4419, -122.1419));
gMap.setMapTypeId(google.maps.MapTypeId.ROADMAP);
I Had the same problem.
The solution for me is:
You must have the same version of: Microsoft.ReportViewer.ProcessingObjectModel registred in C:\Windows\assembly\GAC_MSIL\Microsoft.ReportViewer.ProcessingObjectModel, like you have registraded in web.config in developer server:
In my case i was only registred the 13. version in my prodution server and i have the 12. version in developer server.
the solution is install the version 12. in the prodution server too
the version 12. :
Then now i have the version 12. in the prodution and the report work fine.

Starting another dispatch before your reducer is finished is an anti-pattern, because the state you received at the beginning of your reducer will not be the current application state anymore when your reducer finishes. But scheduling another dispatch from within a reducer is NOT an anti-pattern. In fact, that is what the Elm language does, and as you know Redux is an attempt to bring the Elm architecture to JavaScript.
Here is a middleware that will add the property asyncDispatch
to all of your actions. When your reducer has finished and returned the new application state, asyncDispatch
will trigger store.dispatch
with whatever action you give to it.
// This middleware will just add the property "async dispatch" to all actions
const asyncDispatchMiddleware = store => next => action => {
let syncActivityFinished = false;
let actionQueue = [];
function flushQueue() {
actionQueue.forEach(a => store.dispatch(a)); // flush queue
actionQueue = [];
}
function asyncDispatch(asyncAction) {
actionQueue = actionQueue.concat([asyncAction]);
if (syncActivityFinished) {
flushQueue();
}
}
const actionWithAsyncDispatch =
Object.assign({}, action, { asyncDispatch });
const res = next(actionWithAsyncDispatch);
syncActivityFinished = true;
flushQueue();
return res;
};
Now your reducer can do this:
function reducer(state, action) {
switch (action.type) {
case "fetch-start":
fetch('wwww.example.com')
.then(r => r.json())
.then(r => action.asyncDispatch({ type: "fetch-response", value: r }))
return state;
case "fetch-response":
return Object.assign({}, state, { whatever: action.value });;
}
}
I work for a large corporation and encountered this same error, but needed a different work around. My issue was related to proxy settings. I had my proxy set up so I needed to set my no_proxy to whitelist AWS before I was able to get everything to work. You can set it in your bash script as well if you don't want to muddy up your Python code with os settings.
Python:
import os
os.environ["NO_PROXY"] = "s3.amazonaws.com"
Bash:
export no_proxy = "s3.amazonaws.com"
Edit: The above assume a US East S3 region. For other regions: use s3.[region].amazonaws.com where region is something like us-east-1 or us-west-2

Make sure your id_rsa file doesn't have any extension like .txt or .rtf. Rich Text Format adds additional characters to your file and those gets added to byte array. Which eventually causes invalid private key error. Long story short, Copy the file, not content.
what u need to do is icons downloaded from material design, open that folder there are lots of icons categories specified, open any of it choose any icon and go to this folder -> drawable-anydpi-v21. this folder contains xml files copy any xml file and paste it to this location -> C:\Users\Username\AndroidStudioProjects\ur project name\app\src\main\res\drawable. That's it !! now you can use the icon in ur project.
You can assign default parameter values inline when you first create the mixin:
@mixin clearfix($width: 'auto') {
@if $width == 'auto' {
// if width is not passed, or empty do this
} @else {
display: inline-block;
width: $width;
}
}
This error can also occur when you load all google play services apis when you only using afew.
As stated by google:"In versions of Google Play services prior to 6.5, you had to compile the entire package of APIs into your app. In some cases, doing so made it more difficult to keep the number of methods in your app (including framework APIs, library methods, and your own code) under the 65,536 limit.
From version 6.5, you can instead selectively compile Google Play service APIs into your app."
For example when your app needs play-services-maps ,play-services-location .You need to add only the two apis in your build.gradle file at app level as show below:
compile 'com.google.android.gms:play-services-maps:10.2.1'
compile 'com.google.android.gms:play-services-location:10.2.1'
Instead of:
compile 'com.google.android.gms:play-services:10.2.1'

your default python2.7 is soft linked to the text 'python'
So remove the softlink python
sudo rm -r python
then retry the above command
ls -l
you can see the softlink is removed

Apparently there is not much out there. And a lot of doubt that someone would be willing to provide such a repository. So I solved the problem myself, and am sharing my dataset with anyone else who finds themselves facing the same problem.
You can do it via the constructor of your class:
public class foo {
public foo(){
Bar = "bar";
}
public string Bar {get;set;}
}
If you've got another constructor (ie, one that takes paramters) or a bunch of constructors you can always have this (called constructor chaining):
public class foo {
private foo(){
Bar = "bar";
Baz = "baz";
}
public foo(int something) : this(){
//do specialized initialization here
Baz = string.Format("{0}Baz", something);
}
public string Bar {get; set;}
public string Baz {get; set;}
}
If you always chain a call to the default constructor you can have all default property initialization set there. When chaining, the chained constructor will be called before the calling constructor so that your more specialized constructors will be able to set different defaults as applicable.
I was facing the same issue and then I find a solution. The solution is:
- Close Visual Studio
- Delete the SUO file
- Restart Visual Studio
The .suo file is a hidden file in the same folder where the .svn solution file exists. Hope, it'll work!
multi\hskip0pt-\hskip0pt disciplinary
You can e.g. define like
\def\:{\hskip0pt}
and then write
multi\:-\:disciplinary
Note that the babel Russian language package has its own set of dashes that do not prohibit hyphenation, "~
(double quotation+tilde) for example.
if x
is numeric, then add scale_x_continuous()
; if x
is character/factor, then add scale_x_discrete()
. This might solve your problem.
one more suggestion :
unsigned int a = 0xABCDEF23;
a = ((a&(0x0000FFFF)) << 16) | ((a&(0xFFFF0000)) >> 16);
a = ((a&(0x00FF00FF)) << 8) | ((a&(0xFF00FF00)) >>8);
printf("%0x\n",a);
Have you tried checking the API?
You will need to create a listener for the OnTabSelectedListener
event, then when a user selects any tab you should check if it is the correct one, then change the background color using tabLayout.setBackgroundColor(int color)
, or if it is not the correct tab make sure you change back to the normal color again with the same method.
For those who don't want elegant solutions, just a quick and dirty way to stop those messages, here is a solution that worked for me (I use Hibernate 4.3.6 and Eclipse and no answers provided above (or found on the internet) worked; neither log4j config files nor setting the logging level programatically)

1) localhost:8093/plejson/shop/user <---this link will display all user details
2) localhost:8093/plejson/shop/user/11 <----if i use 11 in link means, it will display particular user 11 details
now I want to use both id and name

It was solved with:
script-src 'self' http://xxxx 'unsafe-inline' 'unsafe-eval';
This is very simple approach. The Advantage is you can get keys as well:
for (var key in array) {
var value = array[key];
console.log(key, value);
}
For ES6:
array.forEach(value => {
console.log(value)
})
For ES6: (If you want value, index and the array itself)
array.forEach((value, index, self) => {
console.log(value, index, self)
})
My answer is quite easy:
Use Entity Framework for communication between C# and your SQL database. That will make parameterized SQL strings that isn't vulnerable to SQL injection.
As a bonus, it's very easy to work with as well.
iframe
s are used a lot to include complete pages. When those pages are hosted on another domain you get problems with cross side scripting and stuff. There are ways to fix this.
Frames were used to divide your page into multiple parts (for example, a navigation menu on the left). Using them is no longer recommended.
Thanks Jason Rogers's answer first.
In Android && cpp should be this:
const char *nativeString = env->GetStringUTFChars(javaString, nullptr);
// use your string
env->ReleaseStringUTFChars(javaString, nativeString);
Can fix this errors:
1.error: base operand of '->' has non-pointer type 'JNIEnv {aka _JNIEnv}'
2.error: no matching function for call to '_JNIEnv::GetStringUTFChars(JNIEnv*&, _jstring*&, bool)'
3.error: no matching function for call to '_JNIEnv::ReleaseStringUTFChars(JNIEnv*&, _jstring*&, char const*&)'
4.add "env->DeleteLocalRef(nativeString);" at end.
there are many ways. as awk
solutions shows, it's the clean solution
sed solution is to delete anything till the last space. So if there is no space at the end, it should work
sed 's/.* //g' <file>
you can avoid sed
also and go for a while
loop.
while read line
do [ -z "$line" ] && continue ;
echo $line|rev|cut -f1 -d' '|rev
done < file
it reads a line, reveres it, cuts the first (i.e. last in the original) and restores back
the same can be done in a pure bash way
while read line
do [ -z "$line" ] && continue ;
echo ${line##* }
done < file
it is called parameter expansion
I know I am replying too late but for anyone else who needs this, run following command from your local machine
cat ~/.ssh/id_rsa.pub | ssh [email protected] "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys"
this has worked perfectly fine. All you need to do is just to replace
with your own user for that particular host
Well from its description it appears it tries to make the user agent's default style consistent across all browsers rather than stripping away all the default styling as a reset would.
Preserves useful defaults, unlike many CSS resets.
For the final, compiled code of your application, the short answer is “no”. Different tools are able to extract different information from the code (e.g. the forms setups) and there are P code decompilers (see Edgar's excellent link for such tools). However, up to this day, there is no decompiler for native code. I'm not aware of anything similar for other high-level languages either.
If you want to avoid the mem cost of using the exec command, I believe you can do better with xargs. I think the following is a more efficient alternative to
find foo -type f ! -name '*Music*' -exec cp {} bar \; # new proc for each exec
find . -maxdepth 1 -name '*Music*' -prune -o -print0 | xargs -0 -i cp {} dest/
If you want to bind to the redis port from your nodejs
container you will have to expose that port in the redis
container:
version: '2'
services:
nodejs:
build:
context: .
dockerfile: DockerFile
ports:
- "4000:4000"
links:
- redis
redis:
build:
context: .
dockerfile: Dockerfile-redis
expose:
- "6379"
The expose
tag will let you expose ports without publishing them to the host machine, but they will be exposed to the containers networks.
https://docs.docker.com/compose/compose-file/#expose
The ports
tag will be mapping the host port with the container port HOST:CONTAINER

Steps are as follows:
Right click your C# project name in Visual Studio's "Solution Explorer";
Then, select "add -> Reference -> COM -> Type Libraries " in order;
Find the "Microsoft Office 16.0 Object Library", and add it to reference (Note: the version number may vary with the OFFICE you have installed);
After doing this, you will see "Microsoft.Office.Interop.Word" under the "Reference" item in your project.
To answer your first question, numpy.correlate(a, v, mode)
is performing the convolution of a
with the reverse of v
and giving the results clipped by the specified mode. The definition of convolution, C(t)=? -8 < i < 8 aivt+i where -8 < t < 8, allows for results from -8 to 8, but you obviously can't store an infinitely long array. So it has to be clipped, and that is where the mode comes in. There are 3 different modes: full, same, & valid:
t
where both a
and v
have some overlap. a
or v
). a
and v
completely overlap each other. The documentation for numpy.convolve
gives more detail on the modes.For your second question, I think numpy.correlate
is giving you the autocorrelation, it is just giving you a little more as well. The autocorrelation is used to find how similar a signal, or function, is to itself at a certain time difference. At a time difference of 0, the auto-correlation should be the highest because the signal is identical to itself, so you expected that the first element in the autocorrelation result array would be the greatest. However, the correlation is not starting at a time difference of 0. It starts at a negative time difference, closes to 0, and then goes positive. That is, you were expecting:
autocorrelation(a) = ? -8 < i < 8 aivt+i where 0 <= t < 8
But what you got was:
autocorrelation(a) = ? -8 < i < 8 aivt+i where -8 < t < 8
What you need to do is take the last half of your correlation result, and that should be the autocorrelation you are looking for. A simple python function to do that would be:
def autocorr(x):
result = numpy.correlate(x, x, mode='full')
return result[result.size/2:]
You will, of course, need error checking to make sure that x
is actually a 1-d array. Also, this explanation probably isn't the most mathematically rigorous. I've been throwing around infinities because the definition of convolution uses them, but that doesn't necessarily apply for autocorrelation. So, the theoretical portion of this explanation may be slightly wonky, but hopefully the practical results are helpful. These pages on autocorrelation are pretty helpful, and can give you a much better theoretical background if you don't mind wading through the notation and heavy concepts.
Q1.) Assuming process B tries to take ownership of the same mutex you locked in process A (you left that out of your pseudocode) then no, process B cannot access sharedResource while the mutex is locked since it will sit waiting to lock the mutex until it is released by process A. It will return from the mutex_lock() function when the mutex is locked (or when an error occurs!)
Q2.) In Process B, ensure you always lock the mutex, access the shared resource, and then unlock the mutex. Also, check the return code from the mutex_lock( pMutex ) routine to ensure that you actually own the mutex, and ONLY unlock the mutex if you have locked it. Do the same from process A.
Both processes should basically do the same thing when accessing the mutex.
lock()
If the lock succeeds, then {
access sharedResource
unlock()
}

Notice that the http code response status you are getting is an HTTP 404. The 404 or Not Found error message is a response code indicating that the client was able to communicate with a given server, but the server could not find what was requested.
If you have got an 403 Forbidden vs 401 Unauthorized HTTP responses then it might make a sense to review your tomcat-users.xml.
Resuming: check the manager resources and files of your server installation, some file/directory might be missing, or the path to the manager resources has been changed.
If you want to launch VM by sending arguments, you should send VM arguments and not Program arguments.
Program arguments are arguments that are passed to your application, which are accessible via the "args" String array parameter of your main method. VM arguments are arguments such as System properties that are passed to the JavaSW interpreter. The Debug configuration above is essentially equivalent to:
java -DsysProp1=sp1 -DsysProp2=sp2 test.ArgsTest pro1 pro2 pro3
The VM arguments go after the call to your Java interpreter (ie, 'java') and before the Java class. Program arguments go after your Java class.
Consider a program ArgsTest.java:
package test;
import java.io.IOException;
public class ArgsTest {
public static void main(String[] args) throws IOException {
System.out.println("Program Arguments:");
for (String arg : args) {
System.out.println("\t" + arg);
}
System.out.println("System Properties from VM Arguments");
String sysProp1 = "sysProp1";
System.out.println("\tName:" + sysProp1 + ", Value:" + System.getProperty(sysProp1));
String sysProp2 = "sysProp2";
System.out.println("\tName:" + sysProp2 + ", Value:" + System.getProperty(sysProp2));
}
}
If given input as,
java -DsysProp1=sp1 -DsysProp2=sp2 test.ArgsTest pro1 pro2 pro3
in the commandline, in project bin folder would give the following result:
Program Arguments: pro1 pro2 pro3 System Properties from VM Arguments Name:sysProp1, Value:sp1 Name:sysProp2, Value:sp2

i was trying to connect to my local server code via post request in postman, and this problem wasted my time alot!
for anyone who uses local project (e.g. postman): use your IPv4 address (type ipconfig in cmd) instead of the "localhost" keyword. in my case:
before:
localhost/app/login
after:
192.168.1.101/app/login
Simply Used this: MessageBox.Show(cmd4.CommandText.ToString()); in c#.net and this will show you main query , Copy it and run in database .

I ran into the same issue and figured out the problem. When you initialize a repository there aren't actually any branches. When you start a project run git add .
and then git commit
and the master branch will be created.
Without checking anything in you have no master branch. In that case you need to follow the steps other people here have suggested.
You need to set the classpath to find your compiled class:
java -cp C:\Users\Matt\workspace\HelloWorld2\bin HelloWorld2
You are comparing the dates as strings, which won't work because the comparison is lexicographical. It's the same issue as when sorting a text file, where a line 20
would appear after a line 100
because the contents are not treated as numbers but as sequences of ASCII codes. In addition, the dates created are all wrong because you are using a string format string where a timestamp is expected (second argument).
Instead of this you should be comparing timestamps of DateTime
objects, for instance:
$paymentDate = date_create();
$contractDateBegin = date_create_from_format('d/m/Y', '01/01/2001');
$contractDateEnd = date_create_from_format('d/m/Y', '01/01/2015');
Your existing conditions will then work correctly.
create a new package, drag and drop the class into it and now you are able to rename the new package
(From https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/readyState)
You can use the react-moment package
-> https://www.npmjs.com/package/react-moment
Put in your file the next line:
import moment from "moment";
date_create: moment().format("DD-MM-YYYY hh:mm:ss")
Comparator
provides a way for you to provide custom comparison logic for types that you have no control over.
Comparable
allows you to specify how objects that you are implementing get compared.
Obviously, if you don't have control over a class (or you want to provide multiple ways to compare objects that you do have control over) then use Comparator
.
Otherwise you can use Comparable
.
Read the data:
foo <- read.table(text="1 349
1 393
1 392
4 459
3 49
3 32
2 94")
And sort:
foo[order(foo$V1),]
This relies on the fact that order
keeps ties in their original order. See ?order
.
I was struggling with the same problem and stumbled upon this page. Another solution I came up with would be this :
In your html, echo the session variable (mine here is $_SESSION['origin']
) to any element of your choosing :
<p id="sessionOrigin"><?=$_SESSION['origin'];?></p>
In your js, using jQuery you can access it like so :
$("#sessionOrigin").text();
EDIT: or even better, put it in a hidden input
<input type="hidden" name="theOrigin" value="<?=$_SESSION['origin'];?>"></input>
Here's an example where the absence of b
would throw a TypeError
exception in Python 3.x
>>> f=open("new", "wb")
>>> f.write("Hello Python!")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'str' does not support the buffer interface
Adding a b
prefix would fix the problem.
Config file:
worker_processes 4; # 2 * Number of CPUs
events {
worker_connections 19000; # It's the key to high performance - have a lot of connections available
}
worker_rlimit_nofile 20000; # Each connection needs a filehandle (or 2 if you are proxying)
# Total amount of users you can serve = worker_processes * worker_connections

I had a question similar to this for homework actually. I was restricted that it must have O(nlogn) efficiency.
I used the idea you proposed of using Mergesort, since it is already of the correct efficiency. I just inserted some code into the merging function that was basically: Whenever a number from the array on the right is being added to the output array, I add to the total number of inversions, the amount of numbers remaining in the left array.
This makes a lot of sense to me now that I've thought about it enough. Your counting how many times there is a greater number coming before any numbers.
hth.
This should work for you:
$('.SeeMore2').click(function(){
var $this = $(this);
$this.toggleClass('SeeMore2');
if($this.hasClass('SeeMore2')){
$this.text('See More');
} else {
$this.text('See Less');
}
});
Here is an example:
List<String> names;
names.add("toto");
names.add("Lala");
names.add("papa");
int index = names.indexOf("papa"); // index = 2
ID3.NET implemented ID3v1.x and ID3v2.3 and supports read/write operations on the ID3 section in MP3 files. There's also a NuGet package available.
If you don't mind getting a new data frame object returned as opposed to updating the original Pandas .assign() will avoid SettingWithCopyWarning
. Your example:
df = df.assign(B=df1['E'])
In case of Java 8 we can also use IntStream
to reverse the array of integers as:
int[] sample = new int[]{1,2,3,4,5};
int size = sample.length;
int[] reverseSample = IntStream.range(0,size).map(i -> sample[size-i-1])
.toArray(); //Output: [5, 4, 3, 2, 1]
Try like this:
if message.value[0] == "/" or message.value[0] == "\\":
do_stuff
The below also happens to answer the Original Poster's question without, the "ugly" conditional code that some commenters have mentioned.
CONTIGUOUS NON-PRINTING Ruby Code
This will work in any mixed language Rails View file, e.g, *.html.erb, *.js.erb, *.rhtml
, etc.
This should also work with STD OUT/printing code, e.g. <%#= f.label :title %>
DETAILS:
Rather than use rails brackets on each line and commenting in front of each starting bracket as we usually do like this:
<%# if flash[:myErrors] %>
<%# if flash[:myErrors].any? %>
<%# if @post.id.nil? %>
<%# if @myPost!=-1 %>
<%# @post = @myPost %>
<%# else %>
<%# @post = Post.new %>
<%# end %>
<%# end %>
<%# end %>
<%# end %>
YOU CAN INSTEAD add only one comment (hashmark/poundsign) to the first open Rails bracket if you write your code as one large block... LIKE THIS:
<%#
if flash[:myErrors] then
if flash[:myErrors].any? then
if @post.id.nil? then
if @myPost!=-1 then
@post = @myPost
else
@post = Post.new
end
end
end
end
%>
Add .idea/*
to your exclusion list to prevent tracking of all .idea files, directories, and sub-resources.
If you were using Spring Boot (you mentioned that you're working with an old application, so you probably aren't but it might be of use to others), then you could use org.springframework.boot.test.rule.OutputCapture in the following manner:
@Rule
public OutputCapture outputCapture = new OutputCapture();
@Test
public void out() {
System.out.print("hello");
assertEquals(outputCapture.toString(), "hello");
}
This worked:
$("#theSelectId").prepend("<option value='' selected='selected'></option>");
Firebug Output:
<select id="theSelectId">
<option selected="selected" value=""/>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
You could also use .prependTo
if you wanted to reverse the order:
?$("<option>", { value: '', selected: true }).prependTo("#theSelectId");???????????
Also if you want to get most frequent value(positive or negative) without loading any modules you can use the following code:
lVals = [1,2,3,1,2,1,1,1,3,2,2,1]
print max(map(lambda val: (lVals.count(val), val), set(lVals)))
I had the same problem on localhost.
Running around the Internet looking for the answer and I approve that adding --allow-file-access-from-files
works. I work on Mac, so for me I had to go through terminal sudo /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --allow-file-access-from-files
and enter your password (if you have one).
Another small thing - nothing will work unless you add to your .xml file the reference to your .xsl file as follows <?xml-stylesheet type="text/xsl" href="<path to file>"?>
. Another small thing I didn't realise immediately - you should be opening your .xml file in browser, no the .xsl.

How can I duplicate it with another Version?
You can detach entity which retrieved from provider, change the key of Entry and then persist it as a new entity.
Create a .reg file containing your proxy settings for your users. Create a batch file setting it to setting it to run the .reg file with the extension /s
On a server using a logon script, tell the logon to run the batch file. Jason
You can send any signal to any process using the kill(2)
interface:
kill -SIGABRT 30823
30823 was a dash
process I started, so I could easily find the process I wanted to kill.
$ /bin/dash
$ Aborted
The Aborted
output is apparently how dash
reports a SIGABRT.
It can be sent directly to any process using kill(2)
, or a process can send the signal to itself via assert(3)
, abort(3)
, or raise(3)
.

How about this?

Or...
>>> int(Decimal(s))

Or...
>>> int(s.split('.')[0])

I doubt it's going to get much simpler than that, I'm afraid. Just accept it and move on.
Indeed ADD go /usr/local/
will add content of go
folder and not the folder itself, you can use Thomasleveil solution or if that did not work for some reason you can change WORKDIR
to /usr/local/
then add your directory to it like:
WORKDIR /usr/local/
COPY go go/
or
WORKDIR /usr/local/go
COPY go ./
But if you want to add multiple folders, it will be annoying to add them like that, the only solution for now as I see it from my current issue is using COPY . .
and exclude all unwanted directories and files in .dockerignore
, let's say I got folders and files:
- src
- tmp
- dist
- assets
- go
- justforfun
- node_modules
- scripts
- .dockerignore
- Dockerfile
- headache.lock
- package.json
and I want to add src assets package.json justforfun go
so:
in Dockerfile:
FROM galaxy:latest
WORKDIR /usr/local/
COPY . .
in .dockerignore file:
node_modules
headache.lock
tmp
dist
Or for more fun (or you like to confuse more people make them suffer as well :P) can be:
*
!src
!assets
!go
!justforfun
!scripts
!package.json
In this way you ignore everything, but excluding what you want to be copied or added only from "ignore list".
It is a late answer but adding more ways to do the same covering even more cases.
Here's an update for those looking for a tidyverse method to extract hh:mm::ss.sssss from a POSIXct object. Note that time zone is not included in the output.
library(hms)
as_hms(times)
Don’t use the DOM to do this. Using the DOM to decode HTML entities (as suggested in the currently accepted answer) leads to differences in cross-browser results.
For a robust & deterministic solution that decodes character references according to the algorithm in the HTML Standard, use the he library. From its README:
he (for “HTML entities”) is a robust HTML entity encoder/decoder written in JavaScript. It supports all standardized named character references as per HTML, handles ambiguous ampersands and other edge cases just like a browser would, has an extensive test suite, and — contrary to many other JavaScript solutions — he handles astral Unicode symbols just fine. An online demo is available.
Here’s how you’d use it:
he.decode("We're unable to complete your request at this time.");
? "We're unable to complete your request at this time."
Disclaimer: I'm the author of the he library.
See this Stack Overflow answer for some more info.
Let's set the terms. The Aggregation is a metaterm in the UML standard, and means BOTH composition and shared aggregation, simply named shared. Too often it is named incorrectly "aggregation". It is BAD, for composition is an aggregation, too. As I understand, you mean "shared".
Further from UML standard:
composite - Indicates that the property is aggregated compositely, i.e., the composite object has responsibility for the existence and storage of the composed objects (parts).
So, University to cathedras association is a composition, because cathedra doesn't exist out of University (IMHO)
Precise semantics of shared aggregation varies by application area and modeler.
I.e., all other associations can be drawn as shared aggregations, if you are only following to some principles of yours or of somebody else. Also look here.
Simpler and a Standard solution to increment the number and to retain the dot at the end. Even if you get the css right, it will not work if your HTML is not correct. see below.
ol {
counter-reset: item;
}
ol li {
display: block;
}
ol li:before {
content: counters(item, ". ") ". ";
counter-increment: item;
}
ol {
counter-reset: item;
li {
display: block;
&:before {
content: counters(item, ". ") ". ";
counter-increment: item
}
}
}
If you add the child make sure the it is under the parent li
.
<!-- WRONG -->
<ol>
<li>Parent 1</li> <!-- Parent is Individual. Not hugging -->
<ol>
<li>Child</li>
</ol>
<li>Parent 2</li>
</ol>
<!-- RIGHT -->
<ol>
<li>Parent 1
<ol>
<li>Child</li>
</ol>
</li> <!-- Parent is Hugging the child -->
<li>Parent 2</li>
</ol>
You can do these conversions also with the .NET Framework:
JSON to XML: by using System.Runtime.Serialization.Json
var xml = XDocument.Load(JsonReaderWriterFactory.CreateJsonReader(
Encoding.ASCII.GetBytes(jsonString), new XmlDictionaryReaderQuotas()));
XML to JSON: by using System.Web.Script.Serialization
var json = new JavaScriptSerializer().Serialize(GetXmlData(XElement.Parse(xmlString)));
private static Dictionary<string, object> GetXmlData(XElement xml)
{
var attr = xml.Attributes().ToDictionary(d => d.Name.LocalName, d => (object)d.Value);
if (xml.HasElements) attr.Add("_value", xml.Elements().Select(e => GetXmlData(e)));
else if (!xml.IsEmpty) attr.Add("_value", xml.Value);
return new Dictionary<string, object> { { xml.Name.LocalName, attr } };
}
If someone wants vertical version of the treeview from Harsh's answer, you can save some time:

}
.tree li::before{
content: '';

}
/*Remove connectors after last child*/
.tree li:last-child::before{

}
/*Time for some hover effects*/
/*We will apply the hover effect the the lineage of the element also*/
.tree li a:hover, .tree li a:hover+ul li a {
background: #c8e4f8; color: #000; border: 1px solid #94a0b4;
}
/*Connector styles on hover*/
.tree li a:hover+ul li::after,
.tree li a:hover+ul li::before,
.tree li a:hover+ul::before,
.tree li a:hover+ul ul::before{
border-color: #94a0b4;
}
Why not use namespaces or classes to nest your values? It may be imperfect, but it is very clean.
public static class ParentClass
{
// here is the "dictionary" class
public static class FooDictionary
{
public const string Key1 = "somevalue";
public const string Foobar = "fubar";
}
}
Now you can access .ParentClass.FooDictionary.Key1, etc.
if string is a variable, use the .repr method on it:
>>> s = '\tgherkin\n'
>>> s
'\tgherkin\n'
>>> print(s)
gherkin
>>> print(s.__repr__())
'\tgherkin\n'
Use StringBuilder
:
StringBuilder sb = new StringBuilder(str);
sb.setCharAt(i - 1, 'k');
str = sb.toString();
I looked to MS to find the answers. The first solution assumes the user account running the application process has access to the shared folder or drive (Same domain). Make sure your DNS is resolved or try using IP address. Simply do the following:
DirectoryInfo di = new DirectoryInfo(PATH);
var files = di.EnumerateFiles("*.*", SearchOption.AllDirectories);
If you want across different domains .NET 2.0 with credentials follow this model:
WebRequest req = FileWebRequest.Create(new Uri(@"\\<server Name>\Dir\test.txt"));
req.Credentials = new NetworkCredential(@"<Domain>\<User>", "<Password>");
req.PreAuthenticate = true;
WebResponse d = req.GetResponse();
FileStream fs = File.Create("test.txt");
// here you can check that the cast was successful if you want.
fs = d.GetResponseStream() as FileStream;
fs.Close();
Looking at the Toolbar
and TintManager
source, drawable/abc_ic_ab_back_mtrl_am_alpha
is tinted with the value of the style attribute colorControlNormal
.
I did try setting this in my project (with <item name="colorControlNormal">@color/my_awesome_color</item>
in my theme), but it's still black for me.
Update:
Found it. You need to set the actionBarTheme
attribute (not actionBarStyle
) with colorControlNormal
.
Eg:
<style name="MyTheme" parent="Theme.AppCompat.Light">
<item name="actionBarTheme">@style/MyApp.ActionBarTheme</item>
<item name="actionBarStyle">@style/MyApp.ActionBar</item>
<!-- color for widget theming, eg EditText. Doesn't effect ActionBar. -->
<item name="colorControlNormal">@color/my_awesome_color</item>
<!-- The animated arrow style -->
<item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>
<style name="MyApp.ActionBarTheme" parent="@style/ThemeOverlay.AppCompat.ActionBar">
<!-- THIS is where you can color the arrow! -->
<item name="colorControlNormal">@color/my_awesome_color</item>
</style>
<style name="MyApp.ActionBarStyle" parent="@style/Widget.AppCompat.Light.ActionBar">
<item name="elevation">0dp</item>
<!-- style for actionBar title -->
<item name="titleTextStyle">@style/ActionBarTitleText</item>
<!-- style for actionBar subtitle -->
<item name="subtitleTextStyle">@style/ActionBarSubtitleText</item>
<!--
the actionBarTheme doesn't use the colorControlNormal attribute
<item name="colorControlNormal">@color/my_awesome_color</item>
-->
</style>
Take a look at realpath
which is available on GNU/Linux, FreeBSD and NetBSD, but not OpenBSD 6.8. I use something like:
CONTAININGDIR=$(realpath ${FILEPATH%/*})
to do what it sounds like you're trying to do.
You can use /start /max [your batch]
it will fill the screen with the program it oppose to /min
Consider using String#format with proper format specifications (%d or %f) instead.
int value = 10;
textView.setText(String.format("%d",value));
This will handle fraction separator and locale specific digits properly
Whitequark responded nicely. But with the current versions of Node.js and Express.js it requires one more line. Make sure to add the 'require http' (second line). I've posted a fuller example here that shows how this call can work. Once running, type http://localhost:8080/?name=abel&fruit=apple
in your browser, and you will get a cool response based on the code.
var express = require('express');
var http = require('http');
var app = express();
app.configure(function(){
app.set('port', 8080);
});
app.get('/', function(req, res){
res.writeHead(200, {'content-type': 'text/plain'});
res.write('name: ' + req.query.name + '\n');
res.write('fruit: ' + req.query.fruit + '\n');
res.write('query: ' + req.query + '\n');
queryStuff = JSON.stringify(req.query);
res.end('That\'s all folks' + '\n' + queryStuff);
});
http.createServer(app).listen(app.get('port'), function(){
console.log("Express server listening on port " + app.get('port'));
})
Adding max-width: 100%;
to the img
tag works for me.

Convert the string to an integer base 16 then to hexadecimal.
print hex(int(string, base=16))
These are built-in functions.

>>> _int = int(string, base=16)
>>> _hex = hex(_int)
>>> print _int
170
>>> print _hex

To trigger an event you basically just call the event handler for that element. Slight change from your code.
var a = document.getElementById("element");
var evnt = a["onclick"];
if (typeof(evnt) == "function") {
evnt.call(a);
}

Try using itertools.count([n])
As long and your input
and label
elements are associated by their id
and for
attributes, you should be able to do something like this:
$('.input').each(function() {
$this = $(this);
$label = $('label[for="'+ $this.attr('id') +'"]');
if ($label.length > 0 ) {
//this input has a label associated with it, lets do something!
}
});
If for
is not set then the elements have no semantic relation to each other anyway, and there is no benefit to using the label tag in that instance, so hopefully you will always have that relationship defined.
You can start reading from here jQuery.ajax()
Actually Controller Action is a public method which can be accessed through Url. So any call of an Action from an Ajax call, either MicrosoftMvcAjax or jQuery can be made. For me, jQuery is the simplest one. It got a lots of examples in the link I gave above. The typical example for an ajax call is like this.
$.ajax({
// edit to add steve's suggestion.
//url: "/ControllerName/ActionName",
url: '<%= Url.Action("ActionName", "ControllerName") %>',
success: function(data) {
// your data could be a View or Json or what ever you returned in your action method
// parse your data here
alert(data);
}
});
More examples can be found in here
There are two options to handle/avoid this situation.
Open the console --> right click --> terminate all.
