To fix the width problem, use the following code instead.
$('input[rel="txtTooltip"]').tooltip({
container: 'body'
});
example: http://eureka.ykyuen.info/2014/10/08/bootstrap-3-tooltip-width/
just another way to do it.
Label lbl = new Label();
new ToolTip().SetToolTip(lbl, "tooltip text here");
Use:
ToolTip tip = new ToolTip();
private void richTextBox1_MouseMove(object sender, MouseEventArgs e)
{
Cursor a = System.Windows.Forms.Cursor.Current;
if (a == Cursors.Hand)
{
Point p = richTextBox1.Location;
tip.Show(
GetWord(richTextBox1.Text,
richTextBox1.GetCharIndexFromPosition(e.Location)),
this,
p.X + e.X,
p.Y + e.Y + 32,
1000);
}
}
Use the GetWord function from my other answer to get the hovered word. Use timer logic to disable reshow the tooltip as in prev. example.
In this example right above, the tool tip shows the hovered word by checking the mouse pointer.
If this answer is still not what you are looking fo, please specify the condition that characterizes the word you want to use tooltip on. If you want it for bolded word, please tell me.

The html
data attribute does exactly what it says it does in the docs. Try this little example, no JavaScript necessary (broken into lines for clarification):
<span rel="tooltip"
data-toggle="tooltip"
data-html="true"
data-title="<table><tr><td style='color:red;'>complex</td><td>HTML</td></tr></table>"
>
hover over me to see HTML
</span>
JSFiddle demos:
This an old question but for people still looking. In JS you can now use the title
property.
button.title = ("Popup text here");
Using the form designer:
You can set also the tool tip programatically using the following call:
this.toolTip1.SetToolTip(this.targetControl, "My Tool Tip");
You should use both title and alt attributes to make it work in all browsers.
<button title="Hello World!" alt="Hello World!">Sample Button</button>
I have CSS class, which determines where to put ellipsis. Based on that, I do the following (element set could be different, i write those, where ellipsis is used, of course it could be a separate class selector):
$(document).on('mouseover', 'input, td, th', function() {
if ($(this).css('text-overflow') && typeof $(this).attr('title') === 'undefined') {
$(this).attr('title', $(this).val());
}
});
At least on firefox, you can set a "title" attribute on the option tag:
<option value="" title="Tooltip">Some option</option>
As for whom
didn't work you have to style the element on which lines are visible in as : white-space: pre-line;

<input type="text" placeholder="specify">
This adds "specify" as tool-tip text inside the input box.
you can update the tooltip text without actually calling show/hide:
$(myEl)
.attr('title', newTitle)
.tooltip('fixTitle')
.tooltip('setContent')
You don't need JavaScript for this at all; just set the title
attribute:
<div title="Hello, World!">
<label>Name</label>
<input type="text"/>
</div>
Note that the visual presentation of the tooltip is browser/OS dependent, so it might fade in and it might not. However, this is the semantic way to do tooltips, and it will work correctly with accessibility software like screen readers.
<div title="Hello, World!">_x000D_
<label>Name</label>_x000D_
<input type="text"/>_x000D_
</div>

The simplest solution I have found is to wrap your Font Awesome Icon in an <a></a>
tag:
<Tooltip title="Node.js" >
<a>
<FontAwesomeIcon icon={faNode} size="2x" />
</a>
</Tooltip>
You can use this to change tooltip-arrow color
.tooltip.bottom .tooltip-arrow {
top: 0;
left: 50%;
margin-left: -5px;
border-bottom-color: #000000; /* black */
border-width: 0 5px 5px;
}
Just subscribe to the control's ToolTipTextNeeded event, and return e.TooltipText, much simpler.
it is possible to add linebreaks within native HTML tooltips by simply having the title attribute spread over mutliple lines.
However, I'd recommend using a jQuery tooltip plugin such as Q-Tip: http://craigsworks.com/projects/qtip/.
It is simple to set up and use. Alternatively there are a lot of free javascript tooltip plugins around too.
edit: correction on first statement.
No, it's not possible, browsers have their own ways to implement tooltip. All you can do is to create some div that behaves like an HTML tooltip (mostly it's just 'show on hover') with Javascript, and then style it the way you want.
With this, you wouldn't have to worry about browser's zooming in or out, since the text inside the tooltip div is an actual HTML, it would scale accordingly.
See Jonathan's post for some good resource.
If you could provide some reason as to why you need to replace the label with a div, that would certainly help...
Also, could you paste a sample that'd be helpful ( http://dpaste.com/ or http://pastebin.com/)
This issue can be solved by login into Ubuntu box using below command:

PHP's mail()
function does not have support for SMTP. You're going to need to use something like the PEAR Mail package.
Here is a sample SMTP mail script:
<?php
require_once("Mail.php");
$from = "Your Name <[email protected]>";
$to = "Their Name <[email protected]>";
$subject = "Subject";
$body = "Lorem ipsum dolor sit amet, consectetur adipiscing elit...";
$host = "mailserver.blahblah.com";
$username = "smtp_username";
$password = "smtp_password";
$headers = array('From' => $from, 'To' => $to, 'Subject' => $subject);
$smtp = Mail::factory('smtp', array ('host' => $host,
'auth' => true,
'username' => $username,
'password' => $password));
$mail = $smtp->send($to, $headers, $body);
if ( PEAR::isError($mail) ) {
echo("<p>Error sending mail:<br/>" . $mail->getMessage() . "</p>");
} else {
echo("<p>Message sent.</p>");
}
?>
Currently, the eyedropper tool is not working in my version of Chrome (as described above), though it worked for me in the past. I hear it is being updated in the latest version of Chrome.
However, I'm able to grab colors easily in Firefox.
In case you cannot get the eyedropper tool to work in Chrome, this is a good work around.
I also find it easier to access :-)

Assuming we're talking SQL Server DateTime
Note: BETWEEN includes both ends of the range, so technically this pattern will be wrong:
errorDate BETWEEN '12/20/2008' AND '12/21/2008'
My preferred method for a time range like that is:
'20081220' <= errorDate AND errordate < '20081221'
Works with common indexes (range scan, SARGable, functionless) and correctly clips off midnight of the next day, without relying on SQL Server's time granularity (e.g. 23:59:59.997)
The --no-ff
option is useful when you want to have a clear notion of your feature branch. So even if in the meantime no commits were made, FF is possible - you still want sometimes to have each commit in the mainline correspond to one feature. So you treat a feature branch with a bunch of commits as a single unit, and merge them as a single unit. It is clear from your history when you do feature branch merging with --no-ff
.
If you do not care about such thing - you could probably get away with FF whenever it is possible. Thus you will have more svn-like feeling of workflow.
For example, the author of this article thinks that --no-ff
option should be default and his reasoning is close to that I outlined above:
Consider the situation where a series of minor commits on the "feature" branch collectively make up one new feature: If you just do "git merge feature_branch" without --no-ff
, "it is impossible to see from the Git history which of the commit objects together have implemented a feature—you would have to manually read all the log messages. Reverting a whole feature (i.e. a group of commits), is a true headache [if --no-ff
is not used], whereas it is easily done if the --no-ff
flag was used [because it's just one commit]."
SELECT FIELD FROM TABLE

As per this link you need to cast to MONEY then INT to avoid ordering '$' as a number.
Answer from 2014 for the people who are down-voting me:
Well, S3 isn't FTP. There are lots and lots of clients that support S3, however.
Pretty much every notable FTP client on OS X has support, including Transmit and Cyberduck.
If you're on Windows, take a look at Cyberduck or CloudBerry.
Updated answer for 2019:
AWS has recently released the AWS Transfer for SFTP service, which may do what you're looking for.
Anonymous classes must extend or implement something, like any other Java class, even if it's just java.lang.Object
.
For example:
Runnable r = new Runnable() {
public void run() { ... }
};
Here, r
is an object of an anonymous class which implements Runnable
.
An anonymous class can extend another class using the same syntax:
SomeClass x = new SomeClass() {
...
};
What you can't do is implement more than one interface. You need a named class to do that. Neither an anonymous inner class, nor a named class, however, can extend more than one class.
you should add style="display:none"
in any of <tr>
that you want to hide.
var text ="";
for (var member in list) {
text += list[member];
}
Normally, for internal commands PowerShell does wait before starting the next command. One exception to this rule is external Windows subsystem based EXE. The first trick is to pipeline to Out-Null
like so:
Notepad.exe | Out-Null
PowerShell will wait until the Notepad.exe process has been exited before continuing. That is nifty but kind of subtle to pick up from reading the code. You can also use Start-Process with the -Wait parameter:
Start-Process <path to exe> -NoNewWindow -Wait
If you are using the PowerShell Community Extensions version it is:
$proc = Start-Process <path to exe> -NoNewWindow -PassThru
$proc.WaitForExit()
Another option in PowerShell 2.0 is to use a background job:
$job = Start-Job { invoke command here }
Wait-Job $job
Receive-Job $job
E.Run runForBreak = new E.Run();
E.Text textForBreak = new E.Text() { Space = SpaceProcessingModeValues.Preserve };
textForBreak.Text = "\n";
runForBreak.Append(textForBreak);
sharedStringItem.Append(runForBreak);
For me this worked perfectly fine .
Intent intent=new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivity(intent);
and add this permission to mainfest file:
<uses-permission android:name="android.permission.CAMERA">
It opens the camera,after capturing the image it saves the image to gallery with a new image set.
How about this?
=IF(ISERROR(MATCH(A1,B:B, 0)), "No Match", INDIRECT(ADDRESS(MATCH(A1,B:B, 0), 3)))
The "3" at the end means for column C.
you can download the pdf file using fetch, and print it with print.js
fetch("url")
.then(function (response) {
response.blob().then(function (blob) {
var reader = new FileReader();
reader.onload = function () {
//Remove the data:application/pdf;base64,
printJS({
printable: reader.result.substring(28),
type: 'pdf',
base64: true
});
};
reader.readAsDataURL(blob);
})
});
They will be initialized to false
by default. In Java arrays are created on heap and every element of the array is given a default value depending on its type. For boolean
data type the default value is false
.
Here are a couple of things to notice in order to understand the connected component's behavior in your code:
The Arity of connect
Matters: connect(mapStateToProps, mapDispatchToProps)
React-Redux calls connect
with the first argument mapStateToProps
, and second argument mapDispatchToProps
.
Therefore, although you've passed in your mapDispatchToProps
, React-Redux in fact treats that as mapState
because it is the first argument. You still get the injected onSubmit
function in your component because the return of mapState
is merged into your component's props. But that is not how mapDispatch
is supposed to be injected.
You may use mapDispatch
without defining mapState
. Pass in null
in place of mapState
and your component will not subject to store changes.
Connected Component Receives dispatch
by Default, When No mapDispatch
Is Provided
Also, your component receives dispatch
because it received null
for its second position for mapDispatch
. If you properly pass in mapDispatch
, your component will not receive dispatch
.
The above answers why the component behaved that way. Although, it is common practice that you simply pass in your action creator using mapStateToProps
's object shorthand. And call that within your component's onSubmit
That is:
import { setAddresses } from '../actions.js'
const Start = (props) => {
// ... omitted
return <div>
{/** omitted */}
<FlatButton
label='Does Not Work'
onClick={this.props.setAddresses({
pickup: this.refs.pickup.state.address,
dropoff: this.refs.dropoff.state.address
})}
/>
</div>
};
const mapStateToProps = { setAddresses };
export default connect(null, mapDispatchToProps)(Start)
There is another simple and elegant option:
parameters.OfType<EmailParameterClass>();
This will remove all elements that are not of type EmailParameterClass
which will obviously filter out any elements of type null
.
Here's a test:
class Test { }
class Program
{
static void Main(string[] args)
{
var list = new List<Test>();
list.Add(null);
Console.WriteLine(list.OfType<Test>().Count());// 0
list.Add(new Test());
Console.WriteLine(list.OfType<Test>().Count());// 1
Test test = null;
list.Add(test);
Console.WriteLine(list.OfType<Test>().Count());// 1
Console.ReadKey();
}
}

A char array is returned by char*, but the function you wrote does not work because you are returning an automatic variable that disappears when the function exits.
Use something like this:
char *testfunc() {
char* arr = malloc(100);
strcpy(arr,"xxxx");
return arr;
}
This is of course if you are returning an array in the C sense, not an std:: or boost:: or something else.
As noted in the comment section: remember to free the memory from the caller.
You can also use df.icol(n)
to access a column by integer.
Update: icol
is deprecated and the same functionality can be achieved by:
df.iloc[:, n] # to access the column at the nth position
And another thing which may cause this problem:
I installed the new ADT (v. 22). It stopped creating gen

I had this issue and I realized that .gitignore file is changed. So, I changed .gitignore and I could pull the changes.
If your code, if the user enters 'X' (for instance), when you reach the while condition evaluation it will determine that 'X' is differente from 'n' (nChar != 'n') which will make your loop condition true and execute the code inside of your loop. The second condition is not even evaluated.
Maybe you can simply
$ sudo bash -c "echo vm.overcommit_memory=1 >> /etc/sysctl.conf"
$ sudo sysctl -p
It works for my case.

If you are using Notepad++ editor Goto ctrl + F choose tab 3 find in files and enter:
This one is:
def binsearch(t, key, low = 0, high = len(t) - 1):
# bisecting the range
while low < high:
mid = (low + high)//2
if t[mid] < key:
low = mid + 1
else:
high = mid
# at this point 'low' should point at the place
# where the value of 'key' is possibly stored.
return low if t[low] == key else -1

The minimum ranges you can rely on are:
short int
and int
: -32,767 to 32,767unsigned short int
and unsigned int
: 0 to 65,535long int
: -2,147,483,647 to 2,147,483,647unsigned long int
: 0 to 4,294,967,295This means that no, long int
cannot be relied upon to store any 10 digit number. However, a larger type long long int
was introduced to C in C99 and C++ in C++11 (this type is also often supported as an extension by compilers built for older standards that did not include it). The minimum range for this type, if your compiler supports it, is:
long long int
: -9,223,372,036,854,775,807 to 9,223,372,036,854,775,807unsigned long long int
: 0 to 18,446,744,073,709,551,615So that type will be big enough (again, if you have it available).
A note for those who believe I've made a mistake with these lower bounds - I haven't. The C requirements for the ranges are written to allow for ones' complement or sign-magnitude integer representations, where the lowest representable value and the highest representable value differ only in sign. It is also allowed to have a two's complement representation where the value with sign bit 1 and all value bits 0 is a trap representation rather than a legal value. In other words, int
is not required to be able to represent the value -32,768.
Regex was proposed already, but not correctly:
<?php
$number = '00000004523423400023402340240';
$withoutLeadingZeroes = preg_replace('/^0+/', '', $number)
echo $withoutLeadingZeroes;
?>
output is then:
4523423400023402340240
Background on Regex:
the ^
signals beginning of string and the +
sign signals more or none of the preceding sign. Therefore, the regex ^0+
matches all zeroes at the beginning of a string.
Create a file named "config.js" in ./src folder with this content:
module.exports = global.config = {
i18n: {
welcome: {
en: "Welcome",
fa: "??? ?????"
}
// rest of your translation object
}
// other global config variables you wish
};
In your main file "index.js" put this line:
import './config';
Everywhere you need your object use this:

As joe mentioned, creating the shell script and then creating an applescript script to call the shell script, will accomplish this, and is quite handy.
Create your shell script in your favorite text editor, for example:
mono "/Volumes/Media/~Users/me/Software/keepass/keepass.exe"
(this runs the w32 executable, using the mono framework)
Save shell script, for my example "StartKeepass.sh"
Open AppleScript Editor, and call the shell script
do shell script "sh /Volumes/Media/~Users/me/Software/StartKeepass.sh" user name "<enter username here>" password "<Enter password here>" with administrator privileges
do shell script
- applescript command to call external shell commands"sh ...."
- this is your shell script (full path) created in step one (you can also run direct commands, I could omit the shell script and just run my mono command here)user name
- declares to applescript you want to run the command as a specific user"<enter username here>
- replace with your username (keeping quotes) ex "josh"password
- declares to applescript your password"<enter password here>"
- replace with your password (keeping quotes) ex "mypass"with administrative privileges
- declares you want to run as an adminsave your applescript as filename.scpt, in my case RunKeepass.scpt
save as... your applescript and change the file format to application, resulting in RunKeepass.app in my case

This is an answer from 2012, the question if from 2009, but people still look at it and there's only one correct (use WebDriver
) and one almost useful (but not good enough) answer.
If you're using Selenium RC and can actually see an alert dialog, then it can't be done. Selenium should handle it for you. But, as stated in Selenium documentation:
Selenium tries to conceal those dialogs from you (by replacing window.alert, window.confirm and window.prompt) so they won’t stop the execution of your page. If you’re seeing an alert pop-up, it’s probably because it fired during the page load process, which is usually too early for us to protect the page.
It is a known limitation of Selenium RC (and, therefore, Selenium IDE, too) and one of the reasons why Selenium 2 (WebDriver) was developed. If you want to handle onload
JS alerts, you need to use WebDriver alert handling.
That said, you can use Robot
or selenium.keyPressNative()
to fill in any text and press Enter and confirm the dialog blindly. It's not the cleanest way, but it could work. You won't be able to get the alert
message, however.
Robot
has all the useful keys mapped to constants, so that will be easy. With keyPressNative()
, you want to use 10
as value for pressing Enter or 27
for Esc since it works with ASCII codes.
This answer is different from the prior answers because it avoids the needless and asymmetric use of the --push
option in the set-url
command of git remote. In this way, both URLs are symmetric in their configuration. For skeptics, the git config as shown by cat ./.git/config
looks different with versus without this option.
git clone [email protected]:myuser/myrepo.git
git remote set-url --add origin [email protected]:myuser/myrepo.git
push
:$ git remote -v
origin [email protected]:myuser/myrepo.git (fetch)
origin [email protected]:myuser/myrepo.git (push)
origin [email protected]:myuser/myrepo.git (push)
$ git config --local --get-regexp ^remote\..+\.url$
remote.origin.url [email protected]:myuser/myrepo.git
remote.origin.url [email protected]:myuser/myrepo.git
git push
To delete an added URL:
git remote set-url --delete origin [email protected]:myuser/myrepo.git

##Unique Approach
##App.getRes().getString(R.string.some_id)
This will work everywhere in app. (Util class, Dialog, Fragment or any class in your app)
(1) Create or Edit (if already exist) your Application
class.
import android.app.Application;
import android.content.res.Resources;
public class App extends Application {
private static App mInstance;
private static Resources res;
@Override
public void onCreate() {
super.onCreate();
mInstance = this;
res = getResources();
}
public static App getInstance() {
return mInstance;
}
public static Resources getRes() {
return res;
}
}
(2) Add name field to your manifest.xml
<application
tag.
<application
android:name=".App"
...
>
...
</application>
Now you are good to go. Use App.getRes().getString(R.string.some_id)
anywhere in app.
Necromancing.
It looks you have just as good a schema to work with as me...
Here is how to do it correctly:
In this example, the table name is dbo.T_SYS_Language_Forms, and the column name is LANG_UID
-- First, chech if the table exists...
IF 0 < (
SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
AND TABLE_SCHEMA = 'dbo'
AND TABLE_NAME = 'T_SYS_Language_Forms'
)
BEGIN
-- Check for NULL values in the primary-key column
IF 0 = (SELECT COUNT(*) FROM T_SYS_Language_Forms WHERE LANG_UID IS NULL)
BEGIN
ALTER TABLE T_SYS_Language_Forms ALTER COLUMN LANG_UID uniqueidentifier NOT NULL
-- No, don't drop, FK references might already exist...
-- Drop PK if exists
-- ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT pk_constraint_name
--DECLARE @pkDropCommand nvarchar(1000)
--SET @pkDropCommand = N'ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT ' + QUOTENAME((SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS
--WHERE CONSTRAINT_TYPE = 'PRIMARY KEY'
--AND TABLE_SCHEMA = 'dbo'
--AND TABLE_NAME = 'T_SYS_Language_Forms'
----AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms'
--))
---- PRINT @pkDropCommand
--EXECUTE(@pkDropCommand)
-- Instead do
-- EXEC sp_rename 'dbo.T_SYS_Language_Forms.PK_T_SYS_Language_Forms1234565', 'PK_T_SYS_Language_Forms';
-- Check if they keys are unique (it is very possible they might not be)
IF 1 >= (SELECT TOP 1 COUNT(*) AS cnt FROM T_SYS_Language_Forms GROUP BY LANG_UID ORDER BY cnt DESC)
BEGIN
-- If no Primary key for this table
IF 0 =
(
SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS
WHERE CONSTRAINT_TYPE = 'PRIMARY KEY'
AND TABLE_SCHEMA = 'dbo'
AND TABLE_NAME = 'T_SYS_Language_Forms'
-- AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms'
)
ALTER TABLE T_SYS_Language_Forms ADD CONSTRAINT PK_T_SYS_Language_Forms PRIMARY KEY CLUSTERED (LANG_UID ASC)
;
-- Adding foreign key
IF 0 = (SELECT COUNT(*) FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS WHERE CONSTRAINT_NAME = 'FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms')
ALTER TABLE T_ZO_SYS_Language_Forms WITH NOCHECK ADD CONSTRAINT FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms FOREIGN KEY(ZOLANG_LANG_UID) REFERENCES T_SYS_Language_Forms(LANG_UID);
END -- End uniqueness check
ELSE
PRINT 'FSCK, this column has duplicate keys, and can thus not be changed to primary key...'
END -- End NULL check
ELSE
PRINT 'FSCK, need to figure out how to update NULL value(s)...'
END
If you want to make your PK auto increment, you need to set the ID column property for that primary key.
See the picture below for better understanding.
// My source is: http://techatplay.wordpress.com/2013/11/22/oracle-sql-developer-create-auto-incrementing-primary-key/
Do this:
<input type="button" name="test" id="test" value="RUN" /><br/>
<?php
function testfun()
{
echo "Your test function on button click is working";
}
if(array_key_exists('test',$_POST)){
testfun();
}
?>
I'll try summarize the great answer by Alex and the jlmendezbonini's point, adding a modification that will make everything ARC compatible (so far it's not since ARC will complain since you should return id
, which means "any object", but BOOL
is not an object type).
- (BOOL) endWorldHunger:(id)largeAmountsOfMonies error:(NSError**)error {
// begin feeding the world's children...
// it's all going well until....
if (ohNoImOutOfMonies) {
// sad, we can't solve world hunger, but we can let people know what went wrong!
// init dictionary to be used to populate error object
NSMutableDictionary* details = [NSMutableDictionary dictionary];
[details setValue:@"ran out of money" forKey:NSLocalizedDescriptionKey];
// populate the error object with the details
if (error != NULL) {
// populate the error object with the details
*error = [NSError errorWithDomain:@"world" code:200 userInfo:details];
}
// we couldn't feed the world's children...return nil..sniffle...sniffle
return NO;
}
// wohoo! We fed the world's children. The world is now in lots of debt. But who cares?
return YES;
}
Now instead of checking for the return value of our method call, we check whether error
is still nil
. If it's not we have a problem.
// initialize NSError object
NSError* error = nil;
// try to feed the world
BOOL success = [self endWorldHunger:smallAmountsOfMonies error:&error];
if (!success) {
// inspect error
NSLog(@"%@", [error localizedDescription]);
}
// otherwise the world has been fed. Wow, your code must rock.

If you want to set the same value on a collection of rows, you can use the update() method combined with any query term to update all rows in one query:
some_list = ModelClass.objects.filter(some condition).values('id')
ModelClass.objects.filter(pk__in=some_list).update(foo=bar)
If you want to update a collection of rows with different values depending on some condition, you can in best case batch the updates according to values. Let's say you have 1000 rows where you want to set a column to one of X values, then you could prepare the batches beforehand and then only run X update-queries (each essentially having the form of the first example above) + the initial SELECT-query.
If every row requires a unique value there is no way to avoid one query per update. Perhaps look into other architectures like CQRS/Event sourcing if you need performance in this latter case.

Yes, a static class can have static constructor, and the use of this constructor is initialization of static member.
static class Employee1
{
static int EmpNo;
static Employee1()
{
EmpNo = 10;
// perform initialization here
}
public static void Add()
{
}
public static void Add1()
{
}
}
and static constructor get called only once when you have access any type member of static class with class name Class1
Suppose you are accessing the first EmployeeName field then constructor get called this time, after that it will not get called, even if you will access same type member.
Employee1.EmployeeName = "kumod";
Employee1.Add();
Employee1.Add();
Why complicate?
std::string removeSpaces(std::string x){
if(x[0] == ' ') { x.erase(0, 1); return removeSpaces(x); }
if(x[x.length() - 1] == ' ') { x.erase(x.length() - 1, x.length()); return removeSpaces(x); }
else return x;
}
This works even if boost was to fail, no regex, no weird stuff nor libraries.

The question is old but I felt the best answer hadn't been given, yet.
Is there an
UPDATE
syntax ... without specifying the column names?
You don't need to know any column names except for some unique column(s) to join on (id
in the example). Works reliably for any possible corner case I can think of.
This is specific to PostgreSQL. I am building dynamic code based on the the information_schema, in particular the table information_schema.columns
, which is defined in the SQL standard and most major RDBMS (except Oracle) have it. But a DO
statement with PL/pgSQL code executing dynamic SQL is totally non-standard PostgreSQL syntax.
DO
$do$
BEGIN
EXECUTE (
SELECT
'UPDATE b
SET (' || string_agg( quote_ident(column_name), ',') || ')
= (' || string_agg('a.' || quote_ident(column_name), ',') || ')
FROM a
WHERE b.id = 123
AND a.id = b.id'
FROM information_schema.columns
WHERE table_name = 'a' -- table name, case sensitive
AND table_schema = 'public' -- schema name, case sensitive
AND column_name <> 'id' -- all columns except id
);
END
$do$;
Assuming a matching column in b
for every column in a
, but not the other way round. b
can have additional columns.
WHERE b.id = 123
is optional, to update a selected row.
Related answers with more explanation:
You still need to know the list of column names that both tables share. With a syntax shortcut for updating multiple columns - shorter than what other answers suggested so far in any case.
UPDATE b
SET ( column1, column2, column3)
= (a.column1, a.column2, a.column3)
FROM a
WHERE b.id = 123 -- optional, to update only selected row
AND a.id = b.id;
This syntax was introduced with Postgres 8.2 in 2006, long before the question was asked. Details in the manual.
Related:
B
If all columns of A
are defined NOT NULL
(but not necessarily B
),
and you know the column names of B
(but not necessarily A
).
UPDATE b
SET (column1, column2, column3, column4)
= (COALESCE(ab.column1, b.column1)
, COALESCE(ab.column2, b.column2)
, COALESCE(ab.column3, b.column3)
, COALESCE(ab.column4, b.column4)
)
FROM (
SELECT *
FROM a
NATURAL LEFT JOIN b -- append missing columns
WHERE b.id IS NULL -- only if anything actually changes
AND a.id = 123 -- optional, to update only selected row
) ab
WHERE b.id = ab.id;
The NATURAL LEFT JOIN
joins a row from b
where all columns of the same name hold same values. We don't need an update in this case (nothing changes) and can eliminate those rows early in the process (WHERE b.id IS NULL
).
We still need to find a matching row, so b.id = ab.id
in the outer query.
db<>fiddle here
Old sqlfiddle.
This is standard SQL except for the FROM
clause.
It works no matter which of the columns are actually present in A
, but the query cannot distinguish between actual NULL values and missing columns in A
, so it is only reliable if all columns in A
are defined NOT NULL
.
There are multiple possible variations, depending on what you know about both tables.
Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.
So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.
Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.
Make sure you're in the right directory (repository main folder) in your local git so it can find .git folder configuration before you commit or add files.
There are, in my opinion, three great python testing frameworks that are good to check out.
unittest - module comes standard with all python distributions
nose - can run unittest tests, and has less boilerplate.
pytest - also runs unittest tests, has less boilerplate, better reporting, lots of cool extra features
To get a good comparison of all of these, read through the introductions to each at http://pythontesting.net/start-here.
There's also extended articles on fixtures, and more there.
Yes, template member functions are perfectly legal and useful on numerous occasions.
The only caveat is that template member functions cannot be virtual.
In case you have a dump made with sqlplus and the output is garbled as someone did not set those 3 values before, there's a way out.
Just a couple hours ago DB admin send me that ugly looking output of query executed in sqlplus (I dunno, maybe he hates me...). I had to find a way out: this is an awk script to parse that output to make it at least more readable. It's far not perfect, but I did not have enough time to polish it properly. Anyway, it does the job quite well.
awk ' function isDashed(ln){return ln ~ /^---+/};function addLn(){ln2=ln1; ln1=ln0;ln0=$0};function isLoaded(){return l==1||ln2!=""}; function printHeader(){hdr=hnames"\n"hdash;if(hdr!=lastHeader){lastHeader=hdr;print hdr};hnames="";hdash=""};function isHeaderFirstLn(){return isDashed(ln0) && !isDashed(ln1) && !isDashed(ln2) }; function isDataFirstLn(){return isDashed(ln2)&&!isDashed(ln1)&&!isDashed(ln0)} BEGIN{_d=1;h=1;hnames="";hdash="";val="";ln2="";ln1="";ln0="";fheadln=""} { addLn(); if(!isLoaded()){next}; l=1; if(h==1){if(!isDataFirstLn()){if(_d==0){hnames=hnames" "ln1;_d=1;}else{hdash=hdash" "ln1;_d=0}}else{_d=0;h=0;val=ln1;printHeader()}}else{if(!isHeaderFirstLn()){val=val" "ln1}else{print val;val="";_d=1;h=1;hnames=ln1}} }END{if(val!="")print val}'
In case anyone else would like to try improve this script, below are the variables: hnames -- column names in the header, hdash - dashed below the header, h -- whether I'm currently parsing header (then ==1), val -- the data, _d - - to swap between hnames and hdash, ln0 - last line read, ln1 - line read previously (it's the one i'm actually working with), ln2 - line read before ln1
Happy parsing!
Oh, almost forgot... I use this to prettify sqlplus output myself:
[oracle@ora ~]$ cat prettify_sql
set lines 256
set trimout on
set tab off
set pagesize 100
set colsep " | "
colsep is optional, but it makes output look like sqlite which is easier to parse using scripts.
EDIT: A little preview of parsed and non-parsed output
The accepted answer doesn't cut it because if a user de-selects a row the list is not updated accordingly.
Here is what I suggest instead:
Private Sub CommandButton2_Click()
Dim lItem As Long
For lItem = 0 To ListBox1.ListCount - 1
If ListBox1.Selected(lItem) = True Then
MsgBox(ListBox1.List(lItem))
End If
Next
End Sub

I always use below approach. I've created one table in database as Table1 with only one column i.e. Row_Id Number (Long Integer) and its value is 0
INSERT INTO <TABLE_NAME_TO_RESET>
SELECT Row_Id AS <COLUMN_NAME_TO_RESET>
FROM Table1;
This will insert one row with 0 value in AutoNumber column, later delete that row.
Solution1:
Solution2: Restarting the device will also solve problem.
Solution3: Wait for 4 to 5 minutes will also works.
No, they're not the same. Aside from the escaping on the client-side that it provides, a prepared statement is compiled on the server-side once, and then can be passed different parameters at each execution. Which means you can do:
$sth = $db->prepare("SELECT * FROM table WHERE foo = ?");
$sth->execute(array(1));
$results = $sth->fetchAll(PDO::FETCH_ASSOC);
$sth->execute(array(2));
$results = $sth->fetchAll(PDO::FETCH_ASSOC);
They generally will give you a performance improvement, although not noticeable on a small scale. Read more on prepared statements (MySQL version).

you can know if user hasn't entered any letter.

This defines text that briefly describes the content of the view. This property is used primarily for accessibility. Since some views do not have textual representation this attribute can be used for providing such.
Non-textual widgets like ImageViews and ImageButtons should use the contentDescription attribute to specify a textual description of the widget such that screen readers and other accessibility tools can adequately describe the user interface.
This link for explanation: Accessibility, It's Impact and Development Resources
Many Android users have disabilities that require them to interact with their Android devices in different ways. These include users who have visual, physical or age-related disabilities that prevent them from fully seeing or using a touchscreen.
Android provides accessibility features and services for helping these users navigate their devices more easily, including text-to-speech, haptic feedback, trackball and D-pad navigation that augments their experience. Android application developers can take advantage of these services to make their applications more accessible and also build their own accessibility services.
This guide is for making your app accessible: Making Apps More Accessible
Making sure your application is accessible to all users is relatively easy, particularly when you use framework-provided user interface components. If you only use these standard components for your application, there are just a few steps required to ensure your application is accessible:
Label your ImageButton, ImageView, EditText, CheckBox and other user interface controls using the android:contentDescription attribute.
Make all of your user interface elements accessible with a directional controller, such as a trackball or D-pad.
Test your application by turning on accessibility services like TalkBack and Explore by Touch, and try using your application using only directional controls.
If you mean the screen where you have that interpreter prompt >>>
you can do CTRL+L on Bash shell can help. Windows does not have equivalent. You can do
import os
os.system('cls') # on windows
or
os.system('clear') # on linux / os x
I have now tried your suggestions and found that it kinda works,
Se my "new" script below:
$('a.cancel').click(function() {
var a = this;
$("#dialog").dialog({
autoOpen: false,
buttons: {
"Ja": function() {
$.post(a.href);
},
"Nej": function() { $(this).dialog("close"); }
},
modal: true,
overlay: {
opacity: 0.5,
background: "black"
}
});
$("#dialog").dialog('open');
return false;
});
});
Any clues?
oh and my Action link now looks like this:
<%= Html.ActionLink("Cancel", "Cancel", new { id = v.BookingId }, new { @class = "cancel" })%>
It's the destructor, it destroys the instance, frees up memory, etc. etc.
Here's a description from ibm.com:
Destructors are usually used to deallocate memory and do other cleanup for a class object and its class members when the object is destroyed. A destructor is called for a class object when that object passes out of scope or is explicitly deleted.
See https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_74/rzarg/cplr380.htm
A bit late, but maybe someone finds it useful.
For me, ISNULL was out of question due to the table scan. UNION ALL would need me to repeat a complex query, and due to me selecting only the TOP X it would not have been very efficient.
If you are able to change the table design, you can:
Add another field, just for sorting, such as Next_Contact_Date_Sort.
Create a trigger that fills that field with a large (or small) value, depending on what you need:
CREATE TRIGGER FILL_SORTABLE_DATE ON YOUR_TABLE AFTER INSERT,UPDATE AS
BEGIN
SET NOCOUNT ON;
IF (update(Next_Contact_Date)) BEGIN
UPDATE YOUR_TABLE SET Next_Contact_Date_Sort=IIF(YOUR_TABLE.Next_Contact_Date IS NULL, 99/99/9999, YOUR_TABLE.Next_Contact_Date_Sort) FROM inserted i WHERE YOUR_TABLE.key1=i.key1 AND YOUR_TABLE.key2=i.key2
END
END
IIF(Fields!HIGHLIGHT_COLOUR.Value="","#FFFFFF","#" & hex(Fields!HIGHLIGHT_COLOUR.Value) & StrDup(6-LEN(hex(Fields!HIGHLIGHT_COLOUR.Value)),"0"))
Is working for me as an expression in font colour
How about just:
public static String intToString(int num, int digits) {
String output = Integer.toString(num);
while (output.length() < digits) output = "0" + output;
return output;
}
yourLabel.intrinsicContentSize.width

If you're using the Symfony framework, there is also a much simpler way using the HttpClientInterface
:
private function remoteFileExists(string $url, HttpClientInterface $client): bool {
$response = $client->request(
'GET',
$url //e.g. http://example.com/file.txt
);
return $response->getStatusCode() == 200;
}
The docs for the HttpClient are also very good and maybe worth looking into if you need a more specific approach: https://symfony.com/doc/current/http_client.html
For all those who don't have the option in Excel (like me), there is a macro which works and is explained here: https://www.get-digital-help.com/2015/08/03/custom-data-labels-in-x-y-scatter-chart/ Very useful
In my case where each splash screen was individually designed instead of autogenerated or laid out in a story board format, I had to stick with my Legacy Launch screen configuration and add portrait and landscape images to target iPhoneX 1125×2436 orientations to the config.xml like so:
<splash height="2436" src="resources/ios/splash/Default-2436h.png" width="1125" />
<splash height="1125" src="resources/ios/splash/Default-Landscape-2436h.png" width="2436" />
After adding these to config.xml ("viewport-fit=cover" was already set in index.hml) my app built with Ionic Pro fills the entire screen on iPhoneX devices.
see http://editorconfig.org and https://docs.microsoft.com/en-us/visualstudio/ide/create-portable-custom-editor-options?view=vs-2017
If it does not exist, add a new file called .editorconfig for your project
manipulate editor config to use your preferred behaviour.
I prefer spaces over tabs, and CRLF for all code files.
Here's my .editorconfig
# http://editorconfig.org
root = true
[*]
indent_style = space
indent_size = 4
end_of_line = crlf
charset = utf-8

I'm not sure how stuck you are:
You must have a web server (Windows comes with one called IIS, but it may not be installed)
http://localhost/
in your browser and see what happens. If nothing happens it means that you may not have IIS installed. See Installing IIS Installing your application
Once you have done that, you can more or less just copy your application to c:\wwwroot\inetpub\
. Read Installing ASP.NET Applications (IIS 6.0) for more information
Accessing the web site from another machine
In theory, once you have a web server running, and the application installed, you only need the IP address
of your web server to access the application.
To find your IP address try:
Start
-> Run
-> type cmd
(hit ENTER
) -> type ipconfig
(hit ENTER
)
Once
you can access your website from another machine in your LAN by just typing in the IP Address of you web server and the correct path to your application.
If you put your application in a directory called NewApp
, you will need to type something like http://your_ip_address/NewApp/default.aspx
Turn off your firewall
If you do have a firewall turn it off while you try connecting for the first time, you can sort that out later.
Usually i prefer like below in swift 3, because i can add file name and create a file easily
let fileManager = FileManager.default
if let documentsURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first {
let databasePath = documentsURL.appendingPathComponent("db.sqlite3").path
print("directory path:", documentsURL.path)
print("database path:", databasePath)
if !fileManager.fileExists(atPath: databasePath) {
fileManager.createFile(atPath: databasePath, contents: nil, attributes: nil)
}
}
If you get this error [email protected] preinstall: ./src/scripts/check_reqs.js && xcodebuild ...

I know this sounds stupid, but don't see it on here yet :). I had this error caused by forgetting the closing bracket on a function and its associated semi-colon since it was anonymous assigned to a var at the end of my controller.
It appears that many issues with the controller (whether caused by injection error, syntax, etc.) cause this error to appear.
you can use the command prompt:
javaw.exe -jar yourfile.jar
Hope it works for you.
Just change +
to -
:
str = str.replace(/[^a-z0-9-]/g, "");
You can read it as:
[^ ]
: match NOT from the set[^a-z0-9-]
: match if not a-z
, 0-9
or -
/ /g

If your settings file is in a web app, they will be in teh web.config file (right below your project. If they are in any other type of project, they will be in the app.config file (also below your project).
Edit
As is pointed out in the comments: your design time application settings are in an app.config file for applications other than web applications. When you build, the app.config file is copied to the output directory, and will be named yourexename.exe.config. At runtime, only the file named yourexename.exe.config will be read.
That example is pretty vague, but maybe something like this?
items = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
items[3:6] = [''.join(items[3:6])]
It basically does a splice (or assignment to a slice) operation. It removes items 3 to 6 and inserts a new list in their place (in this case a list with one item, which is the concatenation of the three items that were removed.)
For any type of list, you could do this (using the +
operator on all items no matter what their type is):
items = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
items[3:6] = [reduce(lambda x, y: x + y, items[3:6])]
This makes use of the reduce
function with a lambda
function that basically adds the items together using the +
operator.
The most likely culprit is Microsoft Internet Information Server. You can stop the service from the command line on Windows 7/Vista:
net stop was /y
or XP:
net stop iisadmin /y

I experienced the same issue for Xcode 7.0 beta. In my case, values for "Provisioning Profile" and "Product bundle identifier" of "Build Settings" differed between PROJECT and TARGETS. I set the same values for them. And I also used the same values for TARGETS of "appName" and "appNameTest". Then closed the project and reopened it. That resolved my case.
This is also an option:
x==2 && dosomething();
dosomething()
will only be called if x==2
is evaluated to true. This is called Short-circuiting.
It is not commonly used in cases like this and you really shouldn't write code like this. I encourage this simpler approach:
if(x==2) dosomething();
You should write readable code at all times; if you are worried about file size, just create a minified version of it with help of one of the many JS compressors. (e.g Google's Closure Compiler)
Assuming you want to use numpy
, you can numerically compute the derivative of a function at any point using the Rigorous definition:
def d_fun(x):
h = 1e-5 #in theory h is an infinitesimal
return (fun(x+h)-fun(x))/h
You can also use the Symmetric derivative for better results:
def d_fun(x):
h = 1e-5
return (fun(x+h)-fun(x-h))/(2*h)
Using your example, the full code should look something like:
def fun(x):
return x**2 + 1
def d_fun(x):
h = 1e-5
return (fun(x+h)-fun(x-h))/(2*h)
Now, you can numerically find the derivative at x=5
:
In [1]: d_fun(5)
Out[1]: 9.999999999621423
Use the File.WriteAllText
method. It creates the file if it doesn't exist and overwrites it if it exists.
As with many tasks in ggplot, the general strategy is to put what you'd like to add to the plot into a data frame in a way such that the variables match up with the variables and aesthetics in your plot. So for example, you'd create a new data frame like this:
dfTab <- as.data.frame(table(df))
colnames(dfTab)[1] <- "x"
dfTab$lab <- as.character(100 * dfTab$Freq / sum(dfTab$Freq))
So that the x
variable matches the corresponding variable in df
, and so on. Then you simply include it using geom_text
:
ggplot(df) + geom_bar(aes(x,fill=x)) +
geom_text(data=dfTab,aes(x=x,y=Freq,label=lab),vjust=0) +
opts(axis.text.x=theme_blank(),axis.ticks=theme_blank(),
axis.title.x=theme_blank(),legend.title=theme_blank(),
axis.title.y=theme_blank())
This example will plot just the percentages, but you can paste
together the counts as well via something like this:
dfTab$lab <- paste(dfTab$Freq,paste("(",dfTab$lab,"%)",sep=""),sep=" ")
Note that in the current version of ggplot2, opts
is deprecated, so we would use theme
and element_blank
now.
Reading answers here, it seems that the error "RenderBox was not laid out" is caused when somehow the ListView size is limitless and this can happen in different scenarios.
Just aiming to help who may have the same case as mine. In my case, I was getting this error because my ListView was inside a a column whose parent was a SingleChildScrollView. I remove this parent and it worked.
Here is my working code:
List _todoList = ["AAA", "BBB"];
...
body: Column(
children: [
Container(...),
Expanded(
child: ListView.builder(
itemCount: _todoList.length,
itemBuilder: (context, index) {
return ListTile(title: Text(_todoList[index]));
}))
],
));
Here how it was when I was getting the "not laid out" error:
List _todoList = ["AAA", "BBB"];
...
body: SingleChildScrollView(child: Column(
children: [
Container(...),
Expanded(
child: ListView.builder(
itemCount: _todoList.length,
itemBuilder: (context, index) {
return ListTile(title: Text(_todoList[index]));
}))
],
)));
I hope this may be useful for someone.
Only "keyboard focusable" elements can be focused with .focus()
. div
aren't meant to be natively focusable. You have to add tabindex="0"
attributes to it to achieve that. input
, button
, a
etc... are natively focusable.
Here is a shorter implementation comparing to @Jav_Rock's
/**
* Round to certain number of decimals
*
* @param d
* @param decimalPlace the numbers of decimals
* @return
*/
public static float round(float d, int decimalPlace) {
return BigDecimal.valueOf(d).setScale(decimalPlace,BigDecimal.ROUND_HALF_UP).floatValue();
}
System.out.println(round(2.345f,2));//two decimal digits, //2.35
Use a StringWriter
instead of a StreamWriter
:
public static string SerializeObject<T>(this T toSerialize)
{
XmlSerializer xmlSerializer = new XmlSerializer(toSerialize.GetType());
using(StringWriter textWriter = new StringWriter())
{
xmlSerializer.Serialize(textWriter, toSerialize);
return textWriter.ToString();
}
}
Note, it is important to use toSerialize.GetType()
instead of typeof(T)
in XmlSerializer constructor: if you use the first one the code covers all possible subclasses of T
(which are valid for the method), while using the latter one will fail when passing a type derived from T
.
Here is a link with some example code that motivate this statement, with XmlSerializer
throwing an Exception
when typeof(T)
is used, because you pass an instance of a derived type to a method that calls SerializeObject that is defined in the derived type's base class: http://ideone.com/1Z5J1.
Also, Ideone uses Mono to execute code; the actual Exception
you would get using the Microsoft .NET runtime has a different Message
than the one shown on Ideone, but it fails just the same.
In case you cannot use Array.Reset
(the variable is not local) then Concat
& ToArray
helps:
anObject.anArray.Concat(new string[] { newArrayItem }).ToArray();
Mr Purple's example I used in mysql trigger like that,
begin
DECLARE n INT DEFAULT 0;
DECLARE i INT DEFAULT 0;
Select COUNT(*) from user where deleted_at is null INTO n;
SET i=0;
WHILE i<n DO
INSERT INTO user_notification(notification_id,status,userId)values(new.notification_id,1,(Select userId FROM user LIMIT i,1)) ;
SET i = i + 1;
END WHILE;
end
If you don care about the range, the following expression will be useful to validate from 1.1.1.1 to 999.999.999.999
"[1-9]{1,3}\\.[1-9]{1,3}\\.[1-9]{1,3}\\.[1-9]{1,3}"
Given a file named Me.Jar:
Use the Java jar
command -- I am using jdk1.8.0_31 so I would type
C:\Program Files (x86)\Java\jdk1.8.0_31\bin\jar xf me.jar
That should extract the file to the folder bin. Look for the file .class in my case my Me.jar contains a Valentine.class
Type java Valentine
and press Enter and your message file will be opened.
you can try typescript's For
:
selectChildren(data , $event){
let parentChecked : boolean = data.checked;
for(let o of this.hierarchicalData){
for(let child of o){
child.checked = parentChecked;
}
}
}
Try this
$("body").css({"background-color":"blue"});

I think you want something like this:
Intent foo = new Intent(this, viewContacts.class);
foo.putExtra("myFirstKey", "myFirstValue");
foo.putExtra("mySecondKey", "mySecondValue");
startActivity(foo);
or you can combine them into a bundle first. Corresponding getExtra() routines exist for the other side. See the intent topic in the dev guide for more information.

To suppress the page number on the first page, add \thispagestyle{empty}
after the \maketitle

I had the same issue and already tried all of solutions but to no avail.
It turned out that using Java 9 was the problem. Installing a lower version Java (jdk 1.8.0_162) worked for me.
Here's a nice method to fill in missing dates into a dataframe, with your choice of fill_value
, days_back
to fill in, and sort order (date_order
) by which to sort the dataframe:
def fill_in_missing_dates(df, date_col_name = 'date',date_order = 'asc', fill_value = 0, days_back = 30):
df.set_index(date_col_name,drop=True,inplace=True)
df.index = pd.DatetimeIndex(df.index)
d = datetime.now().date()
d2 = d - timedelta(days = days_back)
idx = pd.date_range(d2, d, freq = "D")
df = df.reindex(idx,fill_value=fill_value)
df[date_col_name] = pd.DatetimeIndex(df.index)
return df
Some facts about POSIX that are not so bright.
POSIX is also the system call interface or API, and it is nearly 30 years old.
It was designed for serialized data access to local storage, using single computers with single CPUs.
Security was not a major concern in POSIX by design, leading to numerous race condition attacks over the years and forcing programmers to work around these limitations.
Serious bugs are still being discovered, bugs that could have been averted with a more secure POSIX API design.
POSIX expects users to issue one synchronous call at a time and wait for its results before issuing the next. Today's programmers expect to issue many asynchronous requests at a time to improve overall throughput.
This synchronous API is particularly bad for accessing remote and cloud objects, where high latency matters.
My approach is using the attributes collection to add HTML data- attributes from code behind. This is more inline with jquery and client side scripting.
// This would likely be done with findControl in your grid OnItemCreated handler
LinkButton targetBtn = new LinkButton();
// Add attributes
targetBtn.Attributes.Add("data-{your data name here}", value.ToString() );
targetBtn.Attributes.Add("data-{your data name 2 here}", value2.ToString() );
Then retrieve the values through the attribute collection
string val = targetBtn.Attributes["data-{your data name here}"].ToString();
You are copying singleton's customVar
into a singletonVar
variable and changing that variable does not affect the original value in singleton.
// This does not update singleton variable
// It just assigns value of your local variable
Log.d("Test",singletonVar);
singletonVar="World";
Log.d("Test",singletonVar);
// This actually assigns value of variable in singleton
Singleton.customVar = singletonVar;
I had this problem with only with redirectMode="ResponseRewrite"
(redirectMode="ResponseRedirect"
worked fine) and none of the above solutions helped my resolve the issue. However, once I changed the server's application pool's "Managed Pipeline Mode" from "Classic" to "Integrated" the custom error page appeared as expected.
On the i/o 2019 the following solution was presented:
/**

* @param bitmap Image to blur
* @param applicationContext Application context
* @return Blurred bitmap image
*/
@WorkerThread
fun blurBitmap(bitmap: Bitmap, applicationContext: Context): Bitmap {
lateinit var rsContext: RenderScript
try {
// Create the output bitmap
val output = Bitmap.createBitmap(
bitmap.width, bitmap.height, bitmap.config)
// Blur the image
rsContext = RenderScript.create(applicationContext, RenderScript.ContextType.DEBUG)
val inAlloc = Allocation.createFromBitmap(rsContext, bitmap)
val outAlloc = Allocation.createTyped(rsContext, inAlloc.type)
val theIntrinsic = ScriptIntrinsicBlur.create(rsContext, Element.U8_4(rsContext))
theIntrinsic.apply {
setRadius(10f)
theIntrinsic.setInput(inAlloc)
theIntrinsic.forEach(outAlloc)
}
outAlloc.copyTo(output)
return output
} finally {
rsContext.finish()
}
}
Use
$(document).on("click", "#btn_a", function(){

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Create a file_paths xml in app/src/main/res/xml/file_paths.xml
with path
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
Then we need to define file provier to generate Content uri to access file stored in external storage
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">

I like both @Qiao first answer and @Or's addition. For a sake of a little less processing I would like to add to Or's answer.
In @Or's answer keeping track of visited node is great. We can also allow the program to exit sooner that it currently is. At some point in the for loop the current_neighbour
will have to be the end
, and once that happens the shortest path is found and program can return.
I would modify the the method as follow, pay close attention to the for loop
graph = {
1: [2, 3, 4],
2: [5, 6],
3: [10],
4: [7, 8],
5: [9, 10],
7: [11, 12],
11: [13]
}
def bfs(graph_to_search, start, end):
queue = [[start]]
visited = set()
while queue:
# Gets the first path in the queue
path = queue.pop(0)
# Gets the last node in the path
vertex = path[-1]
# Checks if we got to the end
if vertex == end:
return path
# We check if the current node is already in the visited nodes set in order not to recheck it
elif vertex not in visited:
# enumerate all adjacent nodes, construct a new path and push it into the queue
for current_neighbour in graph_to_search.get(vertex, []):
new_path = list(path)
new_path.append(current_neighbour)
queue.append(new_path)
#No need to visit other neighbour. Return at once
if current_neighbour == end
return new_path;
# Mark the vertex as visited
visited.add(vertex)
print bfs(graph, 1, 13)
The output and everything else will be the same. However, the code will take less time to process. This is especially useful on larger graphs. I hope this helps someone in the future.

We built a very simple free/opensource component that adds SAML support for ASP.NET apps https://github.com/jitbit/AspNetSaml
Basically it's just one short C# file you can throw into your project (or install via Nuget) and use it with your app
You can try to clone using the HTTPS
protocol. Terminal command:
git clone https://github.com/RestKit/RestKit.git
The method below returns only the files with certain extension (eg: file with .txt but not .txt1)
public static IEnumerable<string> GetFilesByExtension(string directoryPath, string extension, SearchOption searchOption)
{
return
Directory.EnumerateFiles(directoryPath, "*" + extension, searchOption)
.Where(x => string.Equals(Path.GetExtension(x), extension, StringComparison.InvariantCultureIgnoreCase));
}

function getSummary(id)
{
$.ajax({

Microsoft says here
Table variables does not have distribution statistics, they will not trigger recompiles. Therefore, in many cases, the optimizer will build a query plan on the assumption that the table variable has no rows. For this reason, you should be cautious about using a table variable if you expect a larger number of rows (greater than 100). Temp tables may be a better solution in this case.
You can get around this even more easily with the Rebase extension, just use hg pull --rebase
and your commits are automatically re-comitted to the pulled revision, avoiding the branching issue.
Tips valid for securing any web application
If you want to secure your application, then you should definitely start by using HTTPS instead of HTTP, this ensures a creating secure channel between you & the users that will prevent sniffing the data sent back & forth to the users & will help keep the data exchanged confidential.
You can use JWTs (JSON Web Tokens) to secure RESTful APIs, this has many benefits when compared to the server-side sessions, the benefits are mainly:
1- More scalable, as your API servers will not have to maintain sessions for each user (which can be a big burden when you have many sessions)
2- JWTs are self contained & have the claims which define the user role for example & what he can access & issued at date & expiry date (after which JWT won't be valid)
3- Easier to handle across load-balancers & if you have multiple API servers as you won't have to share session data nor configure server to route the session to same server, whenever a request with a JWT hit any server it can be authenticated & authorized
4- Less pressure on your DB as well as you won't have to constantly store & retrieve session id & data for each request
5- The JWTs can't be tampered with if you use a strong key to sign the JWT, so you can trust the claims in the JWT that is sent with the request without having to check the user session & whether he is authorized or not, you can just check the JWT & then you are all set to know who & what this user can do.
Many libraries provide easy ways to create & validate JWTs in most programming languages, for example: in node.js one of the most popular is jsonwebtoken
Since REST APIs generally aims to keep the server stateless, so JWTs are more compatible with that concept as each request is sent with Authorization token that is self contained (JWT) without the server having to keep track of user session compared to sessions which make the server stateful so that it remembers the user & his role, however, sessions are also widely used & have their pros, which you can search for if you want.
One important thing to note is that you have to securely deliver the JWT to the client using HTTPS & save it in a secure place (for example in local storage).
You can learn more about JWTs from this link
Try giving your table an ID and then using !important
to set border
to none
in CSS. If JavaScript is tampering with your table then that should get around it.
<table id="mytable"
...
table#mytable,
table#mytable td
{
border: none !important;
}
SELECT MAX("field name") AS ("primary key") FROM ("table name")
example:
SELECT MAX(brand) AS brandid FROM brand_tbl
git commit -a -m "Your commit message here"
will quickly commit all changes with the commit message. Git commit "title" and "description" (as you call them) are nothing more than just the first line, and the rest of the lines in the commit message, usually separated by a blank line, by convention. So using this command will just commit the "title" and no description.
If you want to commit a longer message, you can do that, but it depends on which shell you use.
In bash the quick way would be:
git commit -a -m $'Commit title\n\nRest of commit message...'
If you add primary key constraint
ALTER TABLE <TABLE NAME> ADD CONSTRAINT <CONSTRAINT NAME> PRIMARY KEY <COLUMNNAME>
for example:
ALTER TABLE DEPT ADD CONSTRAINT PK_DEPT PRIMARY KEY (DEPTNO)
You cannot move a running docker container from one host to another.
You can commit the changes in your container to an image with docker commit
, move the image onto a new host, and then start a new container with docker run
. This will preserve any data that your application has created inside the container.
Nb: It does not preserve data that is stored inside volumes; you need to move data volumes manually to new host.
Also notice if you call finish() after an intent you can't go back to the previous activity with the "back" button
startActivity(intent);
finish();
The problem is related to Sam´s response:
"have encountered the same problem you have. I found that it may have some relationship with the way you terminate your run result. When you run your code, whether it has a printout, the debugger will call the console which print a "Press any key to continue...". If you terminate the console by pressing key, it's ok; if you do it by click the close button, the problem comes as you described. When you terminate it in the latter way, you have to wait several minutes before you can rebuild your code."
Avoid kill processes, and we have two choices, wait until the process release the .EXE file or this problem will be solved faster restarting the IDE.
I did it like this in Internet Explorer.
function getWindowRelativeOffset(parentWindow, elem) {
var offset = {
left : 0,
top : 0
};
// relative to the target field's document
offset.left = elem.getBoundingClientRect().left;
offset.top = elem.getBoundingClientRect().top;
// now we will calculate according to the current document, this current
// document might be same as the document of target field or it may be
// parent of the document of the target field
var childWindow = elem.document.frames.window;
while (childWindow != parentWindow) {
offset.left = offset.left + childWindow.frameElement.getBoundingClientRect().left;
offset.top = offset.top + childWindow.frameElement.getBoundingClientRect().top;
childWindow = childWindow.parent;
}
return offset;
};
=================== you can call it like this
getWindowRelativeOffset(top, inputElement);
I focus on IE only as per my focus but similar things can be done for other browsers.
i = 20
"%x" % i #=> "14"
I use typeof
to determine if the variable I'm looking at is an object. If it is then I use instanceof
to determine what kind it is
var type = typeof elem;
if (type == "number") {
// do stuff
}
else if (type == "string") {
// do stuff
}
else if (type == "object") { // either array or object
if (elem instanceof Buffer) {
// other stuff
Use dates.tolist()
to convert to native datetime objects, then simply access year
. Example:
>>> dates = np.array(['2010-10-17', '2011-05-13', '2012-01-15'], dtype='datetime64')
>>> [x.year for x in dates.tolist()]
[2010, 2011, 2012]
This is basically the same idea exposed in https://stackoverflow.com/a/35281829/2192272, but using simpler syntax.
Tested with python 3.6 / numpy 1.18.
The yum install php-soap
command will install the Soap module for php 5.x
For installing the correct version for your environment I recommend to create a file info.php
and put this code: <?php echo phpinfo(); ?>
In the header you'll see the version you're using:
Now that you know the correct version you can run this command: yum search php-soap
This command will return the avaliable versions:
php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php54-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php55-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php56-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php70-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php71-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php72-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php73-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php74-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
rh-php70-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
rh-php71-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
rh-php72-php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
Now you just need to choose the correct module to your php version.
For this example, you should run this command php72-php-soap.x86_64
Graphical log viewers, while they might be very good for viewing log files, don't meet the need for a command line utility that can be incorporated into scripts (or batch files). Often such a simple and general-purpose command can be used as part of a specialized solution for a particular environment. Graphical methods don't lend themselves readily to such use.
Something like:
$db = mysqli_connect("localhost", "user", "password", "database");
$name = $db->mysqli_real_escape_string($name);
$query = 'ALTER TABLE assesment ADD ' . $name . ' TINYINT NOT NULL DEFAULT \'0\'';
if($db->query($query)) {
echo "It worked";
}
Haven't tested it but should work.
Can't you style the forms themselves? Then, style the divs accordingly.
form
{
/* styles */
}
You can always overrule inherited styles by making it important:
form
{
/* styles */ !important
}
Please try following
if ([ $dateR -ge 234 ] && [ $dateR -lt 238 ]) || ([ $dateR -ge 834 ] && [ $dateR -lt 838 ]) || ([ $dateR -ge 1434 ] && [ $dateR -lt 1438 ]) || ([ $dateR -ge 2034 ] && [ $dateR -lt 2038 ]) ;
then
echo "WORKING"
else
echo "Out of range!"
You can use PowerShell to run b.bat as administrator from a.bat
:
set mydir=%~dp0
Powershell -Command "& { Start-Process \"%mydir%b.bat\" -verb RunAs}"
It will prompt the user with a confirmation dialog. The user chooses YES
, and then b.bat
will be run as administrator.
You can either create a new Stage
, add your controls into it or if you require the POPUP as Dialog
box, then you may consider using DialogsFX or ControlsFX(Requires JavaFX8)
For creating a new Stage, you can use the following snippet
@Override
public void start(final Stage primaryStage) {
Button btn = new Button();
btn.setText("Open Dialog");
btn.setOnAction(
new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
final Stage dialog = new Stage();
dialog.initModality(Modality.APPLICATION_MODAL);
dialog.initOwner(primaryStage);
VBox dialogVbox = new VBox(20);
dialogVbox.getChildren().add(new Text("This is a Dialog"));
Scene dialogScene = new Scene(dialogVbox, 300, 200);
dialog.setScene(dialogScene);
dialog.show();
}
});
}
If you don't want it to be modal
(block other windows), use:
dialog.initModality(Modality.NONE);
You have to look how this is called:
someObject.equals(someOtherObj);
This invokes the equals
method on the instance of someObject
. Now, inside that method:
public boolean equals(Object obj) { if (obj == this) { //is someObject equal to obj, which in this case is someOtherObj? return true;//If so, these are the same objects, and return true }
You can see that this
is referring to the instance of the object that equals is called on. Note that equals()
is non-static, and so must be called only on objects that have been instantiated.
Note that ==
is only checking to see if there is referential equality; that is, the reference of this
and obj
are pointing to the same place in memory. Such references are naturally equal:
Object a = new Object(); Object b = a; //sets the reference to b to point to the same place as a Object c = a; //same with c b.equals(c);//true, because everything is pointing to the same place
Further note that equals()
is generally used to also determine value equality. Thus, even if the object references are pointing to different places, it will check the internals to determine if those objects are the same:
FancyNumber a = new FancyNumber(2);//Internally, I set a field to 2 FancyNumber b = new FancyNumber(2);//Internally, I set a field to 2 a.equals(b);//true, because we define two FancyNumber objects to be equal if their internal field is set to the same thing.
The error is a stack overflow. That should ring a bell on this site, right? It occurs because a call to poruszanie
results in another call to poruszanie
, incrementing the recursion depth by 1. The second call results in another call to the same function. That happens over and over again, each time incrementing the recursion depth.
Now, the usable resources of a program are limited. Each function call takes a certain amount of space on top of what is called the stack. If the maximum stack height is reached, you get a stack overflow error.

If you don't mind using the Variant data type, then you can use the in-built worksheet function Unique as shown.
sub unique_results_to_array()
dim rng_data as Range
set rng_data = activesheet.range("A1:A10") 'enter the range of data here
dim my_arr() as Variant
my_arr = WorksheetFunction.Unique(rng_data)
first_val = my_arr(1,1)
second_val = my_arr(2,1)
third_val = my_arr(3,1) 'etc...
end sub
The ID is only guaranteed to be generated at flush time. Persisting an entity only makes it "attached" to the persistence context. So, either flush the entity manager explicitely:
em.persist(abc);
em.flush();
return abc.getId();
or return the entity itself rather than its ID. When the transaction ends, the flush will happen, and users of the entity outside of the transaction will thus see the generated ID in the entity.
@Override
public ABC addNewABC(ABC abc) {
abcDao.insertABC(abc);
return abc;
}
Absolute:
The browser will always interpret /
as the root of the hostname. For example, if my site was http://google.com/
and I specified /css/images.css
then it would search for that at http://google.com/css/images.css
. If your project root was actually at /myproject/
it would not find the css file. Therefore, you need to determine where your project folder root is relative to the hostname, and specify that in your href
notation.
Relative: If you want to reference something you know is in the same path on the url - that is, if it is in the same folder, for example http://mysite.com/myUrlPath/index.html
and http://mysite.com/myUrlPath/css/style.css
, and you know that it will always be this way, you can go against convention and specify a relative path by not putting a leading /
in front of your path, for example, css/style.css
.
Filesystem Notations: Additionally, you can use standard filesystem notations like ..
. If you do http://google.com/images/../images/../images/myImage.png
it would be the same as http://google.com/images/myImage.png
. If you want to reference something that is one directory up from your file, use ../myFile.css
.
In your case, you have two options:
<link rel="stylesheet" type="text/css" href="/ServletApp/css/styles.css"/>
<link rel="stylesheet" type="text/css" href="css/styles.css"/>
The first will be more concrete and compatible if you move things around, however if you are planning to keep the file in the same location, and you are planning to remove the /ServletApp/ part of the URL, then the second solution is better.

You need to use the various Bootstrap 4 centering methods...
text-center
for inline elements.justify-content-center
for flexbox elements (ie; form-inline

Also, to offset the column, the col-sm-*
must be contained within a .row

For a Pure CSS approach, you can use the :checked
selector combined with the ::before
selector to inline conditional content.
Just add the class select-checkbox
to your select
element and include the following CSS:
.select-checkbox option::before {
content: "\2610";
width: 1.3em;
text-align: center;
display: inline-block;
}
.select-checkbox option:checked::before {
content: "\2611";
}
You can use plain old unicode characters (with an escaped hex encoding) like these:
\2610
\2611
Or if you want to spice things up, you can use these FontAwesome glyphs
\f096
\f046
select {_x000D_
width: 150px;_x000D_
}_x000D_
_x000D_
.select-checkbox option::before {_x000D_
content: "\2610";_x000D_
width: 1.3em;_x000D_
text-align: center;_x000D_
display: inline-block;_x000D_
}_x000D_
.select-checkbox option:checked::before {_x000D_
content: "\2611";_x000D_
}_x000D_

A PivotTable might suit, though I am not quite certain of the layout of your data:
The bold numbers (one of each pair of duplicates) need not be shown as the field does not have to be subtotalled eg:
Without arc4Random_uniform() in some versions of Xcode(in 7.1 it runs but doesn't autocomplete for me). You can do this instead.
To generate a random number from 0-5. First
import GameplayKit
Then
let diceRoll = GKRandomSource.sharedRandom().nextIntWithUpperBound(6)
I use Use Prettier Formatter and ESLint VS Code extension together for code linting and formating.
now install some packages using given command, if more packages required they will show with installation command as an error in the terminal for you, please install them also.
npm i eslint prettier eslint@^5.16.0 eslint-config-prettier eslint-plugin-prettier eslint-config-airbnb eslint-plugin-node eslint-plugin-import eslint-plugin-jsx-a11y eslint-plugin-react eslint-plugin-react-hooks@^2.5.0 --save-dev
now create a new file name .prettierrc in your project home directory, using this file you can configure settings of the prettier extension, my settings are below:
{
"singleQuote": true
}
now as for the ESlint you can configure it according to your requirement, I am advising you to go Eslint website see the rules (https://eslint.org/docs/rules/)
Now create a file name .eslintrc.json in your project home directory, using that file you can configure eslint, my configurations are below:
{
"extends": ["airbnb", "prettier", "plugin:node/recommended"],
"plugins": ["prettier"],
"rules": {
"prettier/prettier": "error",
"spaced-comment": "off",
"no-console": "warn",
"consistent-return": "off",
"func-names": "off",
"object-shorthand": "off",
"no-process-exit": "off",
"no-param-reassign": "off",
"no-return-await": "off",
"no-underscore-dangle": "off",
"class-methods-use-this": "off",
"prefer-destructuring": ["error", { "object": true, "array": false }],
"no-unused-vars": ["error", { "argsIgnorePattern": "req|res|next|val" }]
}
}
This can be archived by adding code on the onchange event of the select control.
For Example:
<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
<option value="http://gmail.com">Gmail</option>
<option value="http://youtube.com">Youtube</option>
</select>
If you want to call the incremented number directly in a function, this solution works bettter:
Function inc(ByRef data As Integer)
data = data + 1
inc = data
End Function
for example:
Wb.Worksheets(mySheet).Cells(myRow, inc(myCol))
If the function inc()
returns no value, the above line will generate an error.
In Python:
self
argument.self
) or the class (cls
) argument.__init__
is a special function and without overriding __new__
it will always be given the instance of the class as its first argument.
An example using the builtin classmethod and staticmethod decorators:
import sys
class Num:
max = sys.maxint
def __init__(self,num):
self.n = num
def getn(self):
return self.n
@staticmethod
def getone():
return 1
@classmethod
def getmax(cls):
return cls.max
myObj = Num(3)
# with the appropriate decorator these should work fine
myObj.getone()
myObj.getmax()
myObj.getn()
That said, I would try to use @classmethod
/@staticmethod
sparingly. If you find yourself creating objects that consist of nothing but staticmethod
s the more pythonic thing to do would be to create a new module of related functions.
In my case the problem was I had forgotten to add the switch -m before the quoted comment. It may be a common error too, and the error message received is exactly the same
I have not found a perfect solution but the best I could do was to use type="tel" and disable html5 validation (formnovalidate):
<input name="txtTest" type="tel" value="1,200.00" formnovalidate="formnovalidate" />
If the user puts in a comma it will output with the comma in every modern browser i tried (latest FF, IE, edge, opera, chrome, safari desktop, android chrome).
The main problem is:
For my use case I only had to:
If you have a similar requirement this should work for you.
Note: I did not like the support of the pattern attribute. The formnovalidate seems to work much better.
or....
3) Keep a connection to the server, send keep-alives every few minutes, and the server can push messages instantly. This is how Gmail, Google Talk, etc. works.
Identifiers and reserved words should not be case sensitive, although many follow a convention to use capitals for reserved words and Pascal case for identifiers.
See SQL-92 Sec. 5.2
They don't get focus events, so you'll have to use a trick like this: only way to clear it is to clear the entire form
<script type="text/javascript">
$(function() {
$("#wrapper").bind("mouseover", function() {
$("form").get(0).reset();
});
});
</script>
<form>
<div id="wrapper">
<input type=file value="" />
</div>
</form>
You can use <pre>
to display all spaces & blanks you have typed. E.g.:
<pre>
hello, this is
just an example
....
</pre>
Add padding. Padding the element will increase the space between its content and its border. However, note that a box-shadow will begin outside the border, not the content, meaning you can't put space between the shadow and the box. Alternatively you could use :before or :after pseudo selectors on the element to create a slightly bigger box that you place the shadow on, like so: http://jsbin.com/aqemew/edit#source
use the nextSibling
and previousSibling
properties:
<div id="foo1"></div>
<div id="foo2"></div>
<div id="foo3"></div>
document.getElementById('foo2').nextSibling; // #foo3
document.getElementById('foo2').previousSibling; // #foo1
However in some browsers (I forget which) you also need to check for whitespace and comment nodes:
var div = document.getElementById('foo2');
var nextSibling = div.nextSibling;
while(nextSibling && nextSibling.nodeType != 1) {
nextSibling = nextSibling.nextSibling
}
Libraries like jQuery handle all these cross-browser checks for you out of the box.
You can use this:
try {
Resources res = getResources();
InputStream in_s = res.openRawResource(R.raw.help);
byte[] b = new byte[in_s.available()];
in_s.read(b);
txtHelp.setText(new String(b));
} catch (Exception e) {
// e.printStackTrace();
txtHelp.setText("Error: can't show help.");
}
This is fixed in npm 7. See npm/cli#PR169
On Fedora, this works:
yum install lapack lapack-devel blas blas-devel
pip install numpy
pip install scipy
Remember to install 'lapack-devel' and 'blas-devel' in addition to 'blas' and 'lapack' otherwise you'll get the error you mentioned or the "numpy.distutils.system_info.LapackNotFoundError" error.
We could use built-in function repr()
or string interpolation fr'{}'
escape all backwardslashs \
in Python 3.7.*
repr('my_string')
or fr'{my_string}'
Check the Link: https://docs.python.org/3/library/functions.html#repr
Was looking for same. Well, not exactly. I only wanted to list all DOM Nodes.
var currentNode,
ni = document.createNodeIterator(document.documentElement, NodeFilter.SHOW_ELEMENT);
while(currentNode = ni.nextNode()) {
console.log(currentNode.nodeName);
}
To get elements with a specific class, we can use filter function.
var currentNode,
ni = document.createNodeIterator(
document.documentElement,
NodeFilter.SHOW_ELEMENT,
function(node){
return node.classList.contains('toggleable') ? NodeFilter.FILTER_ACCEPT : NodeFilter.FILTER_REJECT;
}
);
while(currentNode = ni.nextNode()) {
console.log(currentNode.nodeName);
}
Found solution on MDN
I updated my requirements.txt
to have
psycopg2==2.7.4 --no-binary=psycopg2
So that it build binaries on source
List<string> items = new List<string>();
items.Find(p => p == "blah");
or
items.Find(p => p.Contains("b"));
but this allows you to define what you are looking for via a match predicate...
I guess if you are talking linqToSql then:
example looking for Account...
DataContext dc = new DataContext();
Account item = dc.Accounts.FirstOrDefault(p => p.id == 5);
If you need to make sure that there is only 1 item (throws exception when more than 1)
DataContext dc = new DataContext();
Account item = dc.Accounts.SingleOrDefault(p => p.id == 5);
