I had a similar issue reading the serial output from a digital scale. I was reading [3:12] out of a 18 characters long output string.
In my case sometimes there is a null character "\x00" (NUL) which magically appears in the scale's reply string and is not printed.
I was getting the error:
> ' 0.00'
> 3 0 fast loop, delta = 10.0 weight = 0.0
> ' 0.00'
> 1 800 fast loop, delta = 10.0 weight = 0.0
> ' 0.00'
> 6 0 fast loop, delta = 10.0 weight = 0.0
> ' 0\x00.0'
> Traceback (most recent call last):
> File "measure_weight_speed.py", line 172, in start
> valueScale = float(answer_string)
> ValueError: invalid literal for float(): 0
After some research I wrote few lines of code that work in my case.
replyScale = scale_port.read(18)
answer = replyScale[3:12]
answer_decode = answer.replace("\x00", "")
answer_strip = str(answer_decode.strip())
print(repr(answer_strip))
valueScale = float(answer_strip)
The answers in these posts helped:
The primitive wrapper types are reference types that are automatically created behind the scenes whenever strings, numbers, or Booleans are read.For example :
var name = "foo";
var firstChar = name.charAt(0);
console.log(firstChar);
This is what happens behind the scenes:
// what the JavaScript engine does
var name = "foo";
var temp = new String(name);
var firstChar = temp.charAt(0);
temp = null;
console.log(firstChar);
Because the second line uses a string (a primitive) like an object, the JavaScript engine creates an instance of String so that charAt(0) will work.The String object exists only for one statement before it’s destroyed check this
The instanceof operator returns false because a temporary object is created only when a value is read. Because instanceof doesn’t actually read anything, no temporary objects are created, and it tells us the values aren’t instances of primitive wrapper types. You can create primitive wrapper types manually
You can delimit your regexp with slashes instead of quotes and then a single backslash to escape the question mark. Try this:
var gent = /I like your Apartment. Could we schedule a viewing\?/g;
Another good method to get an integer representation from binary is to use eval()
Like so:
def getInt(binNum = 0):
return eval(eval('0b' + str(n)))
I guess this is a way to do it too. I hope this is a satisfactory answer :D
No, there's no literal syntax for the empty set. You have to write set()
.
There is no such thing as a byte or short literal. You need to cast to short using (short)100
I hope this answers the intent of the question. Although there are no Booleans in SQL Server, if you have a database that had Boolean types that was translated from Access, the phrase which works in Access was "...WHERE Foo" (Foo is the Boolean column name). It can be replaced by "...WHERE Foo<>0" ... and this works. Good luck!
Well, i guess M represent the mantissa. Decimal can be used to save money, but it doesn't mean, decimal only used for money.
This should help clear up any questions you may have: C# literals

The Java Generics FAQ and therefore also cletus' answer sound like there is no point in having Class<List<T>>
, however the real problem is that this is extremely dangerous:
@SuppressWarnings("unchecked")
Class<List<String>> stringListClass = (Class<List<String>>) (Class<?>) List.class;
List<Integer> intList = new ArrayList<>();
intList.add(1);
List<String> stringList = stringListClass.cast(intList);
// Surprise!
String firstElement = stringList.get(0);
The cast()
makes it look as if it is safe, but in reality it is not safe at all.
Though I don't get where there can't be List<?>.class
= Class<List<?>>
since this would be pretty helpful when you have a method which determines the type based on the generic type of a Class
argument.
For getClass()
there is JDK-6184881 requesting to switch to using wildcards, however it does not look like this change will be performed (very soon) since it is not compatible with previous code (see this comment).
With Java 7 and later version, you can specify a byte literal in this way:
byte aByte = (byte)0b00100001;
Reference: http://docs.oracle.com/javase/8/docs/technotes/guides/language/binary-literals.html
Wherever you want to save the model,
self.saver = tf.train.Saver()
with tf.Session() as sess:
sess.run(tf.global_variables_initializer())
...
self.saver.save(sess, filename)
Make sure, all your tf.Variable
have names, because you may want to restore them later using their names.
And where you want to predict,
saver = tf.train.import_meta_graph(filename)
name = 'name given when you saved the file'
with tf.Session() as sess:
saver.restore(sess, name)
print(sess.run('W1:0')) #example to retrieve by variable name
Make sure that saver runs inside the corresponding session.
Remember that, if you use the tf.train.latest_checkpoint('./')
, then only the latest check point will be used.
I use this code to costum my bottom navigation item
BottomNavigationView navigation = this.findViewById(R.id.my_bottom_navigation);
Menu menu = navigation.getMenu();
menu.findItem(R.id.nav_wall_see).setTitle("Hello");
Another difference between the two loops, which nobody has mentioned before:
Destructuring
for...in
is deprecated. Usefor...of
instead.
So if we want to use destructuring in a loop, for get both index and value of each array element, we should to use the for...of
loop with the Array method entries()
:
for (const [idx, el] of arr.entries()) {
console.log( idx + ': ' + el );
}
if(newStr4.startsWith("Mon") || newStr4.startsWith("Tues") || newStr4.startsWith("Weds") .. etc)
You need to include the whole str.startsWith(otherStr)
for each item, since ||
only works with boolean expressions (true or false).
There are other options if you have a lot of things to check, like regular expressions, but they tend to be slower and more complicated regular expressions are generally harder to read.
An example regular expression for detecting day name abbreviations would be:
if(Pattern.matches("Mon|Tues|Wed|Thurs|Fri", stringToCheck)) {
Good news! Python 3.4 (released March 2014) and Python 2.7.9 (released December 2014) ship with Pip. This is the best feature of any Python release. It makes the community's wealth of libraries accessible to everyone. Newbies are no longer excluded from using community libraries by the prohibitive difficulty of setup. In shipping with a package manager, Python joins Ruby, Node.js, Haskell, Perl, Go—almost every other contemporary language with a majority open-source community. Thank you, Python.
If you do find that pip is not available when using Python 3.4+ or Python 2.7.9+, simply execute e.g.:
py -3 -m ensurepip
Of course, that doesn't mean Python packaging is problem solved. The experience remains frustrating. I discuss this in the Stack Overflow question Does Python have a package/module management system?.
And, alas for everyone using Python 2.7.8 or earlier (a sizable portion of the community). There's no plan to ship Pip to you. Manual instructions follow.
Flying in the face of its 'batteries included' motto, Python ships without a package manager. To make matters worse, Pip was—until recently—ironically difficult to install.
Per https://pip.pypa.io/en/stable/installing/#do-i-need-to-install-pip:
Download get-pip.py
, being careful to save it as a .py
file rather than .txt
. Then, run it from the command prompt:
python get-pip.py
You possibly need an administrator command prompt to do this. Follow Start a Command Prompt as an Administrator (Microsoft TechNet).
This installs the pip package, which (in Windows) contains ...\Scripts\pip.exe that path must be in PATH environment variable to use pip from the command line (see the second part of 'Alternative Instructions' for adding it to your PATH,
The official documentation tells users to install Pip and each of its dependencies from source. That's tedious for the experienced and prohibitively difficult for newbies.
For our sake, Christoph Gohlke prepares Windows installers (.msi
) for popular Python packages. He builds installers for all Python versions, both 32 and 64 bit. You need to:
For me, this installed Pip at C:\Python27\Scripts\pip.exe
. Find pip.exe
on your computer, then add its folder (for example, C:\Python27\Scripts
) to your path (Start / Edit environment variables). Now you should be able to run pip
from the command line. Try installing a package:
pip install httpie
There you go (hopefully)! Solutions for common problems are given below:
If you work in an office, you might be behind an HTTP proxy. If so, set the environment variables http_proxy
and https_proxy
. Most Python applications (and other free software) respect these. Example syntax:
http://proxy_url:port
http://username:password@proxy_url:port
If you're really unlucky, your proxy might be a Microsoft NTLM proxy. Free software can't cope. The only solution is to install a free software friendly proxy that forwards to the nasty proxy. http://cntlm.sourceforge.net/
Python modules can be partly written in C or C++. Pip tries to compile from source. If you don't have a C/C++ compiler installed and configured, you'll see this cryptic error message.
Error: Unable to find vcvarsall.bat
You can fix that by installing a C++ compiler such as MinGW or Visual C++. Microsoft actually ships one specifically for use with Python. Or try Microsoft Visual C++ Compiler for Python 2.7.
Often though it's easier to check Christoph's site for your package.
Note that you can also expand part of argument list:
myfun(1, *("foo", "bar"))
I use
android:scaleX="0.70"
android:scaleY="0.70"
to ajust the size of checkbox
then I set margins like this
android:layout_marginLeft="-10dp"
to adjust ths location of the checkbox.
You can use git log to display the diffs while searching:
git log -p -- path/to/file
I had this problem and the reason was because I copied and pasted a controller into my app. I needed to change ApplicationController
to ApplicationController::Base
Another way to do this is by using the bitstring
module:
>>> from bitstring import BitArray
>>> b = BitArray(bin='11111111')
>>> b.uint
255
Note that the unsigned integer is different from the signed integer:
>>> b.int
-1
The bitstring
module isn't a requirement, but it has lots of performant methods for turning input into and from bits into other forms, as well as manipulating them.
Checkboxes are a control type designed for one purpose: to ensure valid entry of Boolean values.
In Access, there are two types:
2-state -- can be checked or unchecked, but not Null. Values are True (checked) or False (unchecked). In Access and VBA, the value of True is -1 and the value of False is 0. For portability with environments that use 1 for True, you can always test for False or Not False, since False is the value 0 for all environments I know of.
3-state -- like the 2-state, but can be Null. Clicking it cycles through True/False/Null. This is for binding to an integer field that allows Nulls. It is of no use with a Boolean field, since it can never be Null.
Minor quibble with the answers:
There is almost never a need to use the .Value property of an Access control, as it's the default property. These two are equivalent:
?Me!MyCheckBox.Value
?Me!MyCheckBox
The only gotcha here is that it's important to be careful that you don't create implicit references when testing the value of a checkbox. Instead of this:
If Me!MyCheckBox Then
...write one of these options:
If (Me!MyCheckBox) Then ' forces evaluation of the control
If Me!MyCheckBox = True Then
If (Me!MyCheckBox = True) Then
If (Me!MyCheckBox = Not False) Then
Likewise, when writing subroutines or functions that get values from a Boolean control, always declare your Boolean parameters as ByVal unless you actually want to manipulate the control. In that case, your parameter's data type should be an Access control and not a Boolean value. Anything else runs the risk of implicit references.
Last of all, if you set the value of a checkbox in code, you can actually set it to any number, not just 0 and -1, but any number other than 0 is treated as True (because it's Not False). While you might use that kind of thing in an HTML form, it's not proper UI design for an Access app, as there's no way for the user to be able to see what value is actually be stored in the control, which defeats the purpose of choosing it for editing your data.
You can script it with a tool like expect (there are handy bindings too, like Pexpect for Python).
Here's some examples that demonstrate setting and detecting timeouts in jQuery's old and new paradigmes.
Promise with jQuery 1.8+
Promise.resolve(
$.ajax({
url: '/getData',
timeout:3000 //3 second timeout
})
).then(function(){
//do something
}).catch(function(e) {
if(e.statusText == 'timeout')
{
alert('Native Promise: Failed from timeout');
//do something. Try again perhaps?
}
});
jQuery 1.8+
$.ajax({
url: '/getData',
timeout:3000 //3 second timeout
}).done(function(){
//do something
}).fail(function(jqXHR, textStatus){
if(textStatus === 'timeout')
{
alert('Failed from timeout');
//do something. Try again perhaps?
}
});?
jQuery <= 1.7.2
$.ajax({
url: '/getData',
error: function(jqXHR, textStatus){
if(textStatus === 'timeout')
{
alert('Failed from timeout');
//do something. Try again perhaps?
}
},
success: function(){
//do something
},
timeout:3000 //3 second timeout
});
Notice that the textStatus param (or jqXHR.statusText) will let you know what the error was. This may be useful if you want to know that the failure was caused by a timeout.
error(jqXHR, textStatus, errorThrown)
A function to be called if the request fails. The function receives three arguments: The jqXHR (in jQuery 1.4.x, XMLHttpRequest) object, a string describing the type of error that occurred and an optional exception object, if one occurred. Possible values for the second argument (besides null) are "timeout", "error", "abort", and "parsererror". When an HTTP error occurs, errorThrown receives the textual portion of the HTTP status, such as "Not Found" or "Internal Server Error." As of jQuery 1.5, the error setting can accept an array of functions. Each function will be called in turn. Note: This handler is not called for cross-domain script and JSONP requests.
This answer will work to get just the text for any HTML element.
This first parameter "node" is the element to get the text from. The second parameter is optional and if true will add a space between the text within elements if no space would otherwise exist there.
function getTextFromNode(node, addSpaces) {
var i, result, text, child;
result = '';
for (i = 0; i < node.childNodes.length; i++) {
child = node.childNodes[i];
text = null;
if (child.nodeType === 1) {
text = getTextFromNode(child, addSpaces);
} else if (child.nodeType === 3) {
text = child.nodeValue;
}
if (text) {
if (addSpaces && /\S$/.test(result) && /^\S/.test(text)) text = ' ' + text;
result += text;
}
}
return result;
}
Unfortunately ES6/ES2015 doesn't support loading JSON via the module import syntax. But...
There are many ways you can do it. Depending on your needs you can either look into how to read files in JavaScript (window.FileReader
could be an option if you're running in the browser) or use some other loaders as described in other questions (assuming you are using NodeJS).
IMO simplest way is probably to just put the JSON as a JS object into an ES6 module and export it. That way you can just import it where you need it.
Also worth noting if you're using Webpack, importing of JSON files will work by default (since webpack >= v2.0.0
).
import config from '../config.json';
In this simple case you can use vars()
:
an = Animal()
attrs = vars(an)
# {'kids': 0, 'name': 'Dog', 'color': 'Spotted', 'age': 10, 'legs': 2, 'smell': 'Alot'}
# now dump this in some way or another
print(', '.join("%s: %s" % item for item in attrs.items()))
If you want to store Python objects on the disk you should look at shelve — Python object persistence.
This all depends on what sort of access you have to your SAP system. An ABAP program that exports the data and/or an RFC that your macro can call to directly get the data or have SAP create the file is probably best.
However as a general rule people looking for this sort of answer are looking for an immediate solution that does not require their IT department to spend months customizing their SAP system.
In that case you probably want to use SAP GUI Scripting. SAP GUI scripting allows you to automate the Windows SAP GUI in much the same way as you automate Excel. In fact you can call the SAP GUI directly from an Excel macro. Read up more on it here. The SAP GUI has a macro recording tool much like Excel does. It records macros in VBScript which is nearly identical to Excel VBA and can usually be copied and pasted into an Excel macro directly.
Here is a simple example based on a SAP system I have access to.
Public Sub SimpleSAPExport()
Set SapGuiAuto = GetObject("SAPGUI") 'Get the SAP GUI Scripting object
Set SAPApp = SapGuiAuto.GetScriptingEngine 'Get the currently running SAP GUI
Set SAPCon = SAPApp.Children(0) 'Get the first system that is currently connected
Set session = SAPCon.Children(0) 'Get the first session (window) on that connection
'Start the transaction to view a table
session.StartTransaction "SE16"
'Select table T001
session.findById("wnd[0]/usr/ctxtDATABROWSE-TABLENAME").Text = "T001"
session.findById("wnd[0]/tbar[1]/btn[7]").Press
'Set our selection criteria
session.findById("wnd[0]/usr/txtMAX_SEL").text = "2"
session.findById("wnd[0]/tbar[1]/btn[8]").press
'Click the export to file button
session.findById("wnd[0]/tbar[1]/btn[45]").press
'Choose the export format
session.findById("wnd[1]/usr/subSUBSCREEN_STEPLOOP:SAPLSPO5:0150/sub:SAPLSPO5:0150/radSPOPLI-SELFLAG[1,0]").select
session.findById("wnd[1]/tbar[0]/btn[0]").press
'Choose the export filename
session.findById("wnd[1]/usr/ctxtDY_FILENAME").text = "test.txt"
session.findById("wnd[1]/usr/ctxtDY_PATH").text = "C:\Temp\"
'Export the file
session.findById("wnd[1]/tbar[0]/btn[0]").press
End Sub
To help find the names of elements such aswnd[1]/tbar[0]/btn[0]
you can use script recording.
Click the customize local layout button, it probably looks a bit like this:
Then find the Script Recording and Playback menu item.
Within that the More
button allows you to see/change the file that the VB Script is recorded to. The output format is a bit messy, it records things like selecting text, clicking inside a text field, etc.
The provided script should work if copied directly into a VBA macro. It uses late binding, the line Set SapGuiAuto = GetObject("SAPGUI")
defines the SapGuiAuto object.
If however you want to use early binding so that your VBA editor might show the properties and methods of the objects you are using, you need to add a reference to sapfewse.ocx
in the SAP GUI installation folder.
To add something in the first answer, when we want only few records from another table (in this example only one):
INSERT INTO TABLE1
(COLUMN1, COLUMN2, COLUMN3, COLUMN4)
VALUES (value1, value2,
(SELECT COLUMN_TABLE2
FROM TABLE2
WHERE COLUMN_TABLE2 like "blabla"),
value4);
I know executing from sp and insert into temp table or table variable would be an option but I don't think that's your requirement. As per your requirement this below query statement should work:
Declare @sql nvarchar(max)
Set @sql='SELECT col1, col2 FROM OPENROWSET(''SQLNCLI'', ''Server=(local);uid=test;pwd=test'',
''EXEC MyStoredProc ''''param1'''', ''''param2'''''')'
Exec(@sql)
if you have trusted connection then use this below query statement :
Declare @sql nvarchar(max)
Set @sql='SELECT col1, col2 FROM OPENROWSET(''SQLNCLI'', ''Server=(local);Trusted_Connection=yes;'',
''EXEC MyStoredProc ''''param1'''', ''''param2'''''')'
Exec(@sql)
if you are getting error to run the above statement then just run this statement below:
sp_configure 'Show Advanced Options', 1
GO
RECONFIGURE
GO
sp_configure 'Ad Hoc Distributed Queries', 1
GO
RECONFIGURE
GO
I hope this will help someone who will have faced this kind of similar problem. If someone would to try with temp table or table variable that should be like this below but in this scenario you should to know how many columns your sp is returning then you should create that much columns in temp table or table variable:
--for table variable
Declare @t table(col1 col1Type, col2 col2Type)
insert into @t exec MyStoredProc 'param1', 'param2'
SELECT col1, col2 FROM @t
--for temp table
create table #t(col1 col1Type, col2 col2Type)
insert into #t exec MyStoredProc 'param1', 'param2'
SELECT col1, col2 FROM #t
If you opt to convert this inside return( ) of render method, easiest option would be using map( ) method. Map your array into JSX syntax using map() function, as shown below (ES6 syntax is used).
Inside parent component:
<tbody>
{ objectArray.map(object => <ObjectRow key={object.id} object={object.value}>) }
</tbody>
Please note the key
attribute added to your child component. If you didn't provide a key attribute, you can see the following warning on your console.
Warning: Each child in an array or iterator should have a unique "key" prop.
Note: One common mistake people do is using index
as key when iterating, using index
of the element as a key is an anti-pattern and you can read more about it here. In short, if it's NOT a static list never use index
as key.
Now at the ObjectRow component, you can access the object from its properties.
Inside ObjectRow component
const { object } = this.props
or
const object = this.props.object
This should fetch you the object you passed from parent component to the variable object
in ObjectRow component. Now you can spit out the values in that object according to your purpose.
References :
You only need to include a throws clause on a method if the method throws a checked exception. If the method throws a runtime exception then there is no need to do so.
See here for some background on checked vs unchecked exceptions: http://download.oracle.com/javase/tutorial/essential/exceptions/runtime.html
If the method catches the exception and deals with it internally (as in your second example) then there is no need to include a throws clause.

Use DATESTR
>> datestr(40189)
ans =
12-Jan-0110
Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM
>> datenum(2010,1,11)
ans =
734149
>> datenum(2010,1,11)-40189
ans =
693960
>> datestr(40189+693960)
ans =
11-Jan-2010
In other words, to convert any serial Excel date, call
datestr(excelSerialDate + 693960)
EDIT
To get the date in mm/dd/yyyy format, call datestr
with the specified format
excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010
Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things
excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010
In my current organization, we don't do this in master but do do it on both develop and release/ branches (we are using Git Flow), in order to generate snapshot builds.
As we are using a multi branch pipeline, we do this in the Jenkinsfile with the when{} syntax...
stage {

branch 'develop'
}
}
}

From a comment:
I want to sort each set.
That's easy. For any set s
(or anything else iterable), sorted(s)
returns a list of the elements of s
in sorted order:
>>> s = set(['0.000000000', '0.009518000', '10.277200999', '0.030810999', '0.018384000', '4.918560000'])
>>> sorted(s)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '10.277200999', '4.918560000']
Note that sorted
is giving you a list
, not a set
. That's because the whole point of a set, both in mathematics and in almost every programming language,* is that it's not ordered: the sets {1, 2}
and {2, 1}
are the same set.
You probably don't really want to sort those elements as strings, but as numbers (so 4.918560000 will come before 10.277200999 rather than after).
The best solution is most likely to store the numbers as numbers rather than strings in the first place. But if not, you just need to use a key
function:
>>> sorted(s, key=float)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '4.918560000', '10.277200999']
For more information, see the Sorting HOWTO in the official docs.
* See the comments for exceptions.
If you don't want to use temporary tables here is a split string like function you can use
SET @Array = 'one,two,three,four';
SET @ArrayIndex = 2;
SELECT CASE
WHEN @Array REGEXP CONCAT('((,).*){',@ArrayIndex,'}')
THEN SUBSTRING_INDEX(SUBSTRING_INDEX(@Array,',',@ArrayIndex+1),',',-1)
ELSE NULL
END AS Result;
SUBSTRING_INDEX(string, delim, n)
returns the first nSUBSTRING_INDEX(string, delim, -1)
returns the last onlyREGEXP '((delim).*){n}'
checks if there are n delimiters (i.e. you are in bounds)I don't like that much solutions based on multiplying text-shadows, it's not really flexible, it may work for a 2 pixels stroke where directions to add are 8, but with just 3 pixels stroke directions became 16, and so on... Not really confortable to manage.
The right tool exists, it's SVG <text>
The browsers' support problem worth nothing in this case, 'cause the usage of text-shadow has its own support problem too,
filter: progid:DXImageTransform
can be used or IE < 10 but often doesn't work as expected.
To me the best solution remains SVG with a fallback in not-stroked text for older browser:
This kind of approuch works on pratically all versions of Chrome and Firefox, Safari since version 3.04, Opera 8, IE 9
Compared to text-shadow
whose supports are:
Chrome 4.0,
FF 3.5,
IE 10,
Safari 4.0,
Opera 9, it results even more compatible.

var item = Items.Select(x => x.Id == 123).FirstOrDefault();
Other than that, I'm not sure how much more concise you can get, without maybe writing your own specialized "First" and "FirstOrDefault" extension methods.
I understand that its been answered already. but I hope this will help someone in future and saves so much time and pain.
complete code is below: This one I did for a textbox to make it Autocomplete in CiviCRM. Hope it helps someone
CRM.$( 'input[id^=custom_78]' ).autocomplete({
autoFill: true,
select: function (event, ui) {
var label = ui.item.label;
var value = ui.item.value;
// Update subject field to add book year and book product
var book_year_value = CRM.$('select[id^=custom_77] option:selected').text().replace('Book Year ','');
//book_year_value.replace('Book Year ','');
var subject_value = book_year_value + '/' + ui.item.label;
CRM.$('#subject').val(subject_value);
CRM.$( 'input[name=product_select_id]' ).val(ui.item.value);
CRM.$('input[id^=custom_78]').val(ui.item.label);
return false;
},
source: function(request, response) {
CRM.$.ajax({
url: productUrl,
data: {
'subCategory' : cj('select[id^=custom_77]').val(),
's': request.term,
},
beforeSend: function( xhr ) {
xhr.overrideMimeType( "text/plain; charset=x-user-defined" );
},
success: function(result){
result = jQuery.parseJSON( result);
//console.log(result);
response(CRM.$.map(result, function (val,key) {
//console.log(key);
//console.log(val);
return {
label: val,
value: key
};
}));
}
})
.done(function( data ) {
if ( console && console.log ) {
// console.log( "Sample of dataas:", data.slice( 0, 100 ) );
}
});
}
});
PHP code on how I'm returning data to this jquery ajax call in autocomplete:
/**
* This class contains all product related functions that are called using AJAX (jQuery)
*/
class CRM_Civicrmactivitiesproductlink_Page_AJAX {
static function getProductList() {
$name = CRM_Utils_Array::value( 's', $_GET );
$name = CRM_Utils_Type::escape( $name, 'String' );
$limit = '10';
$strSearch = "description LIKE '%$name%'";
$subCategory = CRM_Utils_Array::value( 'subCategory', $_GET );
$subCategory = CRM_Utils_Type::escape( $subCategory, 'String' );
if (!empty($subCategory))
{
$strSearch .= " AND sub_category = ".$subCategory;
}
$query = "SELECT id , description as data FROM abc_books WHERE $strSearch";
$resultArray = array();
$dao = CRM_Core_DAO::executeQuery( $query );
while ( $dao->fetch( ) ) {
$resultArray[$dao->id] = $dao->data;//creating the array to send id as key and data as value
}
echo json_encode($resultArray);
CRM_Utils_System::civiExit();
}
}
Ok, so in a comment above the question asker Fidilip
said that what he/she's really after is to get the path to the current element.
Here's a script that will "climb" the DOM ancestor tree and then build fairly specific selector including any id
or class
attributes on the item clicked.
See it working on jsFiddle: http://jsfiddle.net/Jkj2n/209/
<!DOCTYPE html>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script>
$(function() {
$("*").on("click", function(e) {
e.preventDefault();
var selector = $(this)
.parents()
.map(function() { return this.tagName; })
.get()
.reverse()
.concat([this.nodeName])
.join(">");
var id = $(this).attr("id");
if (id) {
selector += "#"+ id;
}
var classNames = $(this).attr("class");
if (classNames) {
selector += "." + $.trim(classNames).replace(/\s/gi, ".");
}
alert(selector);
});
});
</script>

eval:
This is very powerful, but is also very dangerous if you accept strings to evaluate from untrusted input. Suppose the string being evaluated is "os.system('rm -rf /')" ? It will really start deleting all the files on your computer.
ast.literal_eval:
Safely evaluate an expression node or a string containing a Python literal or container display. The string or node provided may only consist of the following Python literal structures: strings, bytes, numbers, tuples, lists, dicts, sets, booleans, None, bytes and sets.
Syntax:
eval(expression, globals=None, locals=None)
import ast
ast.literal_eval(node_or_string)
Example:
# python 2.x - doesn't accept operators in string format
import ast
ast.literal_eval('[1, 2, 3]') # output: [1, 2, 3]
ast.literal_eval('1+1') # output: ValueError: malformed string
# python 3.0 -3.6
import ast
ast.literal_eval("1+1") # output : 2
ast.literal_eval("{'a': 2, 'b': 3, 3:'xyz'}") # output : {'a': 2, 'b': 3, 3:'xyz'}
# type dictionary
ast.literal_eval("",{}) # output : Syntax Error required only one parameter
ast.literal_eval("__import__('os').system('rm -rf /')") # output : error
eval("__import__('os').system('rm -rf /')")
# output : start deleting all the files on your computer.
# restricting using global and local variables
eval("__import__('os').system('rm -rf /')",{'__builtins__':{}},{})
# output : Error due to blocked imports by passing '__builtins__':{} in global
# But still eval is not safe. we can access and break the code as given below
s = """

lambda n: [

eval(s, {'__builtins__':{}})
In the above code ().__class__.__bases__[0]
nothing but object itself.
Now we instantiated all the subclasses, here our main enter code here
objective is to find one class named n from it.
We need to code
object and function
object from instantiated subclasses. This is an alternative way from CPython
to access subclasses of object and attach the system.
From python 3.7 ast.literal_eval() is now stricter. Addition and subtraction of arbitrary numbers are no longer allowed. link

for those who still face the same problem which i faced before when i have a ViewPager
with 7 fragments. the default for these fragments to load the English content from API
service but the problem here that i want to change the language from settings activity and after finish
settings activity i want ViewPager
in main activity to refresh the fragments to match the language selection from the user and load the Arabic content if user chooses Arabic here what i did to work from the first time
1- You must use FragmentStatePagerAdapter as mentioned above.
2- on mainActivity i override the onResume and did the following
if (!(mPagerAdapter == null)) {
mPagerAdapter.notifyDataSetChanged();
}
3-i overrided the getItemPosition()
in mPagerAdapter and make it return POSITION_NONE
.
@Override
public int getItemPosition(Object object) {
return POSITION_NONE;
}
works like charm
I just learnt this myself the other day: the this keyword defines that method has being an extension of the class that proceeds it. So for your example, MyClass will have a new extension method called Foo (which doesn't accept any parameter and returns an int; it can be used as with any other public method).
write.csv(t, "t.csv", row.names=FALSE)
From ?write.csv
:
row.names: either a logical value indicating whether the row names of
‘x’ are to be written along with ‘x’, or a character vector
of row names to be written.
UPDATE 2019: You can bypass X-Frame-Options
in an <iframe>

In Dojo 1.7 or newer, use domConstruct.empty(String|DomNode)
:
require(["dojo/dom-construct"], function(domConstruct){
// Empty node's children byId:
domConstruct.empty("someId");
});
In older Dojo, use dojo.empty(String|DomNode)
(deprecated at Dojo 1.8):
dojo.empty( id or DOM node );
Each of these empty
methods safely removes all children of the node.
int var1 = int.Parse(ds.Tables[0].Rows[0][3].ToString());
int var2 = int.Parse(ds.Tables[0].Rows[0][4].ToString());
Try this, you will know the difference between change and modify,
ALTER TABLE table_name CHANGE curr_column_name new_column_name new_column_datatype [constraints]
ALTER TABLE table_name MODIFY column_name new_column_datatype [constraints]
CHANGE
.MODIFY
. You cannot change the name of the column using this statement.Hope, I explained well in detail.
Swift 5.2, UIView+Extension
extension UIView {
public func addViewBorder(borderColor:CGColor,borderWith:CGFloat,borderCornerRadius:CGFloat){
self.layer.borderWidth = borderWith
self.layer.borderColor = borderColor
self.layer.cornerRadius = borderCornerRadius
}
}
You used this extension;
yourView.addViewBorder(borderColor: #colorLiteral(red: 0.6, green: 0.6, blue: 0.6, alpha: 1), borderWith: 1.0, borderCornerRadius: 20)
while(choice!=99)
{
cin>>choice;
if (choice==99)
exit(0);
cin>>gNum;
}
Trust me, that will exit the loop. If that doesn't work nothing will. Mind, this may not be what you want...
Try this:
import React, { useCallback } from "react";
import { Linking } from "react-native";
OpenWEB = () => {
Linking.openURL(url);
};
const App = () => {

};
Hope this will solve your problem.
I use this combination of extension methods:
public static Stream Copy(this Stream source)
{
if (source == null)
return null;
long originalPosition = -1;
if (source.CanSeek)
originalPosition = source.Position;
MemoryStream ms = new MemoryStream();
try
{
Copy(source, ms);
if (originalPosition > -1)
ms.Seek(originalPosition, SeekOrigin.Begin);
else
ms.Seek(0, SeekOrigin.Begin);
return ms;
}
catch
{
ms.Dispose();
throw;
}
}
public static void Copy(this Stream source, Stream target)
{
if (source == null)
throw new ArgumentNullException("source");
if (target == null)
throw new ArgumentNullException("target");
long originalSourcePosition = -1;
int count = 0;
byte[] buffer = new byte[0x1000];
if (source.CanSeek)
{
originalSourcePosition = source.Position;
source.Seek(0, SeekOrigin.Begin);
}
while ((count = source.Read(buffer, 0, buffer.Length)) > 0)
target.Write(buffer, 0, count);
if (originalSourcePosition > -1)
{
source.Seek(originalSourcePosition, SeekOrigin.Begin);
}
}
I had a similar issue on 16.04 VPS Digital Ocean. If you are changing crontabs, make sure to run
sudo service cron restart
My solution without using moment
is to convert it to a timestamp, add the timezone offset, then convert back to a date object, and then run the toISOString()
var date = new Date(); // Or the date you'd like converted.
var isoDateTime = new Date(date.getTime() - (date.getTimezoneOffset() * 60000)).toISOString();
Here is what I think is a much clearer way to check if a variable is defined:
var_defined() {
local var_name=$1
set | grep "^${var_name}=" 1>/dev/null
return $?
}
Use it as follows:
if var_defined foo; then
echo "foo is defined"
else
echo "foo is not defined"
fi

using (OdbcConnection DbConnection = new OdbcConnection("ConnectionString"))
{
DbConnection.Open();
using (OdbcCommand DbCommand = DbConnection.CreateCommand())

DbCommand.CommandText = "INSERT...";
DbCommand.Parameters.Add("@Name", OdbcType.Text, 20).Value = "name";
DbCommand.ExecuteNonQuery();
DbCommand.Parameters.Clear();
DbCommand.Parameters.Add("@Name", OdbcType.Text, 20).Value = "name2";
DbCommand.ExecuteNonQuery();
}
}
you need to go to the root directory and run the below command
source bin/activate
Once the above command is executed, you will be able to create custom apps
The following code is looking for '\0', and under the assumptions of the question the array can be considered sorted since all non-'\0' precede all '\0'. This assumption won't hold if the array can contain '\0' within the data.
Find the location of the first zero-byte using a binary search, then slice.
You can find the zero-byte like this:
package main
import "fmt"
func FirstZero(b []byte) int {
min, max := 0, len(b)
for {
if min + 1 == max { return max }
mid := (min + max) / 2
if b[mid] == '\000' {
max = mid
} else {
min = mid
}
}
return len(b)
}
func main() {
b := []byte{1, 2, 3, 0, 0, 0}
fmt.Println(FirstZero(b))
}
It may be faster just to naively scan the byte array looking for the zero-byte, especially if most of your strings are short.
Just wanted to drop a note. I was having trouble formatting a text 4000 field that had a mind of its own and the text would seeming wrap (or not wrap) randomly on the report. When I updated the column using the replace chr(10) noted above. My report finally formatted as I wanted. Many Thanx!
Dont make name with capital letters . Always use lowercase for naming . This will work fine . like companyLogo.png will raise error but company_logo.png will work fine.
TL:DR version:
//Objective-C
[self.picker selectRow:2 inComponent:0 animated:YES];
//Swift
picker.selectRow(2, inComponent:0, animated:true)
Either you didn't set your picker to select the row (which you say you seem to have done but anyhow):
- (void)selectRow:(NSInteger)row inComponent:(NSInteger)component animated:(BOOL)animated
OR you didn't use the the following method to get the selected item from your picker
- (NSInteger)selectedRowInComponent:(NSInteger)component
This will get the selected row as Integer from your picker and do as you please with it. This should do the trick for yah. Good luck.
Anyhow read the ref: https://developer.apple.com/documentation/uikit/uipickerview

EDIT for Swift solution (Source: Dan Beaulieu's answer)
Define an Outlet:
@IBOutlet weak var pickerView: UIPickerView! // for example
Then in your viewWillAppear or your viewDidLoad, for example, you can use the following:
pickerView.selectRow(rowMin, inComponent: 0, animated: true)
pickerView.selectRow(rowSec, inComponent: 1, animated: true)
If you inspect the Swift 2.0 framework you'll see .selectRow defined as:
func selectRow(row: Int, inComponent component: Int, animated: Bool)
option clicking .selectRow in Xcode displays the following:
Based on solution, presented by @Dakusan (the class defining to extend the HashMap), I did it this way:
public static HashMap<String,String> SetHash(String...pairs) {
HashMap<String,String> rtn = new HashMap<String,String>(pairs.length/2);
for ( int n=0; n < pairs.length; n+=2 ) rtn.put(pairs[n], pairs[n + 1]);
return rtn;
}
.. and using it this way:
HashMap<String,String> hm = SetHash( "one","aa", "two","bb", "tree","cc");
(Not sure if there is any disadvantages in that way (I am not a java developer, just has to do some task in java), but it works and seems to me comfortable.)
just change the content-type to application/json when you use JSON with POST/PUT, etc...
The pixels array is stored in the "data" attribute of cv::Mat. Let's suppose that we have a Mat matrix where each pixel has 3 bytes (CV_8UC3).
For this example, let's draw a RED pixel at position 100x50.
Mat foo;
int x=100, y=50;
Solution 1:
Create a macro function that obtains the pixel from the array.
#define PIXEL(frame, W, x, y) (frame+(y)*3*(W)+(x)*3)
//...
unsigned char * p = PIXEL(foo.data, foo.rols, x, y);
p[0] = 0; // B
p[1] = 0; // G
p[2] = 255; // R
Solution 2:
Get's the pixel using the method ptr.
unsigned char * p = foo.ptr(y, x); // Y first, X after
p[0] = 0; // B
p[1] = 0; // G
p[2] = 255; // R
You're over-complicating it - it just needs to be:
void generateArray(int *a, int si)
{
for (int j = 0; j < si; j++)
a[j] = rand() % 9;
}
int main()
{
const int size=5;
int a[size];
generateArray(a, size);
return 0;
}
When you pass an array as a parameter to a function it decays to a pointer to the first element of the array. So there is normally never a need to pass a pointer to an array.
You would use the os module system method.
You just put in the string form of the command, the return value is the windows enrivonment variable COMSPEC
For example:
os.system('python') opens up the windows command prompt and runs the python interpreter
I was trying to connect to a VM running SQL Server 2015 from my laptop in a Visual Studio 2015 Console App. I run my app the night before and it is fine. In the morning I try to debug the app and I get this error. I tried ipconfig/flush
and release
+ renew
and a a bunch of other garbage, but in the end...
Restart your VM and restart the client. That fixed it for me. I should have known, restart works every time.
The problem is that .gitignore
ignores just files that weren't tracked before (by git add
). Run git reset name_of_file
to unstage the file and keep it. In case you want to also remove the given file from the repository (after pushing), use git rm --cached name_of_file
.
If you want to use only FileInfo class try this
string oldPath = @"C:\MyFolder\Myfile.xyz";
string newpath = @"C:\NewFolder\";
string newFileName = "new file name";
FileInfo f1 = new FileInfo(oldPath);
if(f1.Exists)
{
if(!Directory.Exists(newpath))
{
Directory.CreateDirectory(newpath);
}
f1.CopyTo(string.Format("{0}{1}{2}", newpath, newFileName, f1.Extension));
}
First of all, let's try to make your code a little simpler:
// No need to create a circle unless it is clearly necessary to
// demonstrate the problem
// Your Rect2f defines a default constructor, so let's use it for simplicity.
shared_ptr<Shape> rect(new Rect2f());
Okay, so now we see that the parentheses are clearly balanced. What else could it be? Let's check the following code snippet's error:
int main() {
delete new T();
}
This may seem like weird usage, and it is, but I really hate memory leaks. However, the output does seem useful:
In function 'int main()':
Line 2: error: expected type-specifier before 'T'
Aha! Now we're just left with the error about the parentheses. I can't find what causes that; however, I think you are forgetting to include the file that defines Rect2f
.
Apart of directly writing HTML on the PrintWriter obtained from the response (which is the standard way of outputting HTML from a Servlet), you can also include an HTML fragment contained in an external file by using a RequestDispatcher:
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("HTML from an external file:");
request.getRequestDispatcher("/pathToFile/fragment.html")
.include(request, response);
out.close();
}
As far as your question goes: no, if activating from .ini
is not enough and you can't upgrade PHP, there's not much you can do. Some modules, but not all, can be added without recompilation (zypper install php5-soap
, yum install php-soap
). If it is not enough, try installing some PEAR class for interpreted SOAP support (NuSOAP, etc.).
In general, the double-dash --switches
are designed to be used when recompiling PHP from scratch.
You would download the PHP source package (as a compressed .tgz
tarball, say), expand it somewhere and then, e.g. under Linux, run the configure script
./configure --prefix ...
The configure
command used by your PHP may be shown with phpinfo()
. Repeating it identical should give you an exact copy of the PHP you now have installed. Adding --enable-soap
will then enable SOAP in addition to everything else.
That said, if you aren't familiar with PHP recompilation, don't do it. It also requires several ancillary libraries that you might, or might not, have available - freetype
, gd
, libjpeg
, XML
, expat
, and so on and so forth (it's not enough they are installed; they must be a developer version, i.e. with headers and so on; in most distributions, having libjpeg
installed might not be enough, and you might need libjpeg-dev
also).
I have to keep a separate virtual machine with everything installed for my recompilation purposes.
If you're using Chrome Canary (or Beta), just check the 'Hide Violations' option.

To follow up on Ron's answer if using JQuery and putting it in application.js or the head section you need to wrap it in a ready() section...
$(document).ready(function() {
$('#my-link').click(function(event){
alert('Hooray!');
event.preventDefault(); // Prevent link from following its href
});
});
I think the simplest way is:
dos2unix $(find . -type f)
SET session_replication_role = replica;
also dosent work for me in Postgres 9.1. i use the two function described by bartolo-otrit with some modification. I modified the first function to make it work for me because the namespace or the schema must be present to identify the table correctly. The new code is :
CREATE OR REPLACE FUNCTION disable_triggers(a boolean, nsp character varying)
RETURNS void AS
$BODY$
declare
act character varying;
r record;
begin
if(a is true) then
act = 'disable';
else
act = 'enable';
end if;
for r in select c.relname from pg_namespace n
join pg_class c on c.relnamespace = n.oid and c.relhastriggers = true
where n.nspname = nsp
loop
execute format('alter table %I.%I %s trigger all', nsp,r.relname, act);
end loop;
end;
$BODY$
LANGUAGE plpgsql VOLATILE
COST 100;
ALTER FUNCTION disable_triggers(boolean, character varying)
OWNER TO postgres;
then i simply do a select query for every schema :
SELECT disable_triggers(true,'public');
SELECT disable_triggers(true,'Adempiere');
this is the solution I ended up using in sqlserver 2012 (since all the other suggestions had the drawback of truncating fractional part or some other drawback).
declare @float float = 1000000000.1234;
select format(@float, N'#.##############################');
output:
1000000000.1234
this has the further advantage (in my case) to make thousands separator and localization easy:
select format(@float, N'#,##0.##########', 'de-DE');
output:
1.000.000.000,1234
This can be done with a CSS hack (see the other answers), but it can also be done very easily with JavaScript.
Set the div's width to (for example) 50%, use JavaScript to check its width, and then set the height accordingly. Here's a code example using jQuery:
$(function() {_x000D_
var div = $('#dynamicheight');_x000D_
var width = div.width();_x000D_
_x000D_
div.css('height', width);_x000D_
});
_x000D_
#dynamicheight_x000D_
{_x000D_
width: 50%;_x000D_
_x000D_
/* Just for looks: */_x000D_
background-color: cornflowerblue;_x000D_
margin: 25px;_x000D_
}
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="dynamicheight"></div>
_x000D_
If you want the box to scale with the browser window on resize, move the code to a function and call it on the window resize event. Here's a demonstration of that too (view example full screen and resize browser window):
$(window).ready(updateHeight);_x000D_
$(window).resize(updateHeight);_x000D_
_x000D_
function updateHeight()_x000D_
{_x000D_
var div = $('#dynamicheight');_x000D_
var width = div.width();_x000D_
_x000D_
div.css('height', width);_x000D_
}
_x000D_
#dynamicheight_x000D_
{_x000D_
width: 50%;_x000D_
_x000D_
/* Just for looks: */_x000D_
background-color: cornflowerblue;_x000D_
margin: 25px;_x000D_
}
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="dynamicheight"></div>
_x000D_
You can change that default behavior in your .gitconfig
, for example:
[push]
default = current
To check the current settings, run:
git config --global --get push.default
try: ctrl + P
type: @
followed by the name of the class,method or variable name you search for.
There is no overload for DateTime values, but you can get the long value Ticks
that is what the values contain, compare them and then create a new DateTime value from the result:
new DateTime(Math.Min(Date1.Ticks, Date2.Ticks))
(Note that the DateTime structure also contains a Kind
property, that is not retained in the new value. This is normally not a problem; if you compare DateTime values of different kinds the comparison doesn't make sense anyway.)
Update: it is supported as of TypeScript 3.7 and called Optional chaining: https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html#optional-chaining
I can't find any reference to it whatsoever in the TypeScript language specification.
As far as what to call this operator in CoffeeScript, it's called the existential operator (specifically, the "accessor variant" of the existential operator).
From CoffeeScript's documentation on Operators:
The accessor variant of the existential operator
?.
can be used to soak up null references in a chain of properties. Use it instead of the dot accessor.
in cases where the base value may be null or undefined.
So, the accessor variant of the existential operator appears to be the proper way to refer to this operator; and TypeScript does not currently appear to support it (although others have expressed a desire for this functionality).
Here's my attempt at doing this:

The only thing I wasn't able to do was to make it fill the entire width of the Toolbar
. If someone could help me do that then that'd be golden.
This is an old topic and I'd like to add my understanding here to expand the knowledge of this interesting topic.
The key difference between REM and :: is:
REM is a command itself, while :: is NOT.
We can treat :: as a token that as soon as CMD parser encounters the first non-blank space in a line is this :: token, it will just skip the whole line and read next line. That's why REM should be followed by at least a blank space to be able to function as a comment for the line, while :: does not need any blank space behind it.
That REM is a command itself can be best understood from the following FOR syntax
The basic FOR syntax is as follows
FOR %v in (set) DO <Command> [command param]
here <Command>
can be any valid command
So we can write the following valid command line as rem
is a command
FOR %i in (1,2,3) DO rem echo %i
However, we CANNOT write the following line as ::
is not a command
FOR %i in (1,2,3) DO :: echo %i
I ran into this problem some days ago, for a pure NodeJS answer I would suggest using Stream to merge the chunks together.
var http = require('http'),
Stream = require('stream').Transform,
fs = require('fs');
var url = 'http://www.google.com/images/srpr/logo11w.png';
http.request(url, function(response) {
var data = new Stream();
response.on('data', function(chunk) {
data.push(chunk);
});
response.on('end', function() {
fs.writeFileSync('image.png', data.read());
});
}).end();
The newest Node versions won't work well with binary strings, so merging chunks with strings is not a good idea when working with binary data.
*Just be careful when using 'data.read()', it will empty the stream for the next 'read()' operation. If you want to use it more than once, store it somewhere.
You could modify the project configuration temporarily to save only the last 1 build, reload the configuration (which should trash the old builds), then change the configuration setting again to your desired value.
You might want to use TRUNC function on your column when comparing with string format, so it compares only till seconds, not milliseconds.
SELECT * FROM <table_name> WHERE id = 1
AND TRUNC(usagetime, 'SS') = '2012-09-03 08:03:06';
If you wanted to truncate upto minutes, hours, etc. that is also possible, just use appropriate notation instead of 'SS':
hour ('HH'), minute('MI'), year('YEAR' or 'YYYY'), month('MONTH' or 'MM'), Day ('DD')
From GC Performance Tuning training documents of Oracle:
-Xmn[size]: Size of young generation heap space.
Applications with emphasis on performance tend to use -Xmn to size the young generation, because it combines the use of -XX:MaxNewSize and -XX:NewSize and almost always explicitly sets -XX:PermSize and -XX:MaxPermSize to the same value.
In short, it sets the NewSize and MaxNewSize values of New generation to the same value.
The reason is that the compiler has to actually see the definition in order to be able to drop it in in place of the call.
Remember that C and C++ use a very simplistic compilation model, where the compiler always only sees one translation unit at a time. (This fails for export, which is the main reason only one vendor actually implemented it.)
String search = "A";
for(String s : myList)
if(s.contains(search)) return true;
return false;
This will iterate over each string in the list, and check if it contains the string you're looking for. If it's only spaces you want to trap for, you can do this:
String search = "A";
for(String s : myList)
if(s.replaceAll(" ","").contains(search)) return true;
return false;
which will first replace spaces with empty strings before searching. Additionally, if you just want to trim the string first, you can do:
String search = "A";
for(String s : myList)
if(s.trim().contains(search)) return true;
return false;
I'm not sure I have followed your question- are you trying to attach a child view to the RelativeLayout? If so you want to do something along the lines of:
RelativeLayout item = (RelativeLayout)findViewById(R.id.item);
View child = getLayoutInflater().inflate(R.layout.child, null);
item.addView(child);
Application.Exit
is for Windows Forms applications - it informs all message pumps that they should terminate, waits for them to finish processing events and then terminates the application. Note that it doesn't necessarily force the application to exit.
Environment.Exit
is applicable for all Windows applications, however it is mainly intended for use in console applications. It immediately terminates the process with the given exit code.
In general you should use Application.Exit
in Windows Forms applications and Environment.Exit
in console applications, (although I prefer to let the Main
method / entry point run to completion rather than call Environment.Exit
in console applications).
For more detail see the MSDN documentation.

I would use the minted package as mentioned from the developer Konrad Rudolph instead of the listing package. Here is why:
listing package
The listing package does not support colors by default. To use colors you would need to include the color package and define color-rules by yourself with the \lstset command as explained for matlab code here.
Also, the listing package doesn't work well with unicode, but you can fix those problems as explained here and here.
The following code
\documentclass{article}
\usepackage{listings}
\begin{document}
\begin{lstlisting}[language=html]
<html>
<head>
<title>Hello</title>
</head>
<body>Hello</body>
</html>
\end{lstlisting}
\end{document}
produces the following image:
minted package
The minted package supports colors, unicode and looks awesome. However, in order to use it, you need to have python 2.6 and pygments. In Ubuntu, you can check your python version in the terminal with
python --version
and you can install pygments with
sudo apt-get install python-pygments
Then, since minted makes calls to pygments, you need to compile it with -shell-escape like this
pdflatex -shell-escape yourfile.tex
If you use a latex editor like TexMaker or something, I would recommend to add a user-command, so that you can still compile it in the editor.
The following code
\documentclass{article}
\usepackage{minted}
\begin{document}
\begin{minted}{html}
<!DOCTYPE html>
<html>
<head>
<title>Hello</title>
</head>
<body>Hello</body>
</html>
\end{minted}
\end{document}
produces the following image:
They are both data formats for hierarchical data, so while the syntax is quite different, the structure is similar. Example:
JSON:
{
"persons": [
{
"name": "Ford Prefect",
"gender": "male"
},
{
"name": "Arthur Dent",
"gender": "male"
},
{
"name": "Tricia McMillan",
"gender": "female"
}
]
}
XML:
<persons>
<person>
<name>Ford Prefect</name>
<gender>male</gender>
</person>
<person>
<name>Arthur Dent</name>
<gender>male</gender>
</person>
<person>
<name>Tricia McMillan</name>
<gender>female</gender>
</person>
</persons>
The XML format is more advanced than shown by the example, though. You can for example add attributes to each element, and you can use namespaces to partition elements. There are also standards for defining the format of an XML file, the XPATH language to query XML data, and XSLT for transforming XML into presentation data.
The XML format has been around for some time, so there is a lot of software developed for it. The JSON format is quite new, so there is a lot less support for it.
While XML was developed as an independent data format, JSON was developed specifically for use with Javascript and AJAX, so the format is exactly the same as a Javascript literal object (that is, it's a subset of the Javascript code, as it for example can't contain expressions to determine values).
And if you are looking for changes only among certain file(s), then:
git diff branch1 branch2 -- myfile1.js myfile2.js
branch1 is optional and your current branch (the branch you are on) will be considered by default if branch1 is not provided. e.g:
git diff master -- controller/index.js
This takes care of nulls
var body = JObject.Parse("anyjsonString");
body?.SelectToken("path-string-prop")?.ToString();
body?.SelectToken("path-double-prop")?.ToObject<double>();
Possibly you want to specify PATH
— and also ORACLE_HOME
and LD_LIBRARY_PATH
— so that cron(1)
knows where to find binaries.

I like to use such static methods:
$result = $purchases_repository->matching(
Criteria::create()->where(
Criteria::expr()->gt('prize', 200)
)
);
Of course, you can push logic when it is 1 condition, but when you have more conditions it is better to divide it into fragments, configure and pass it to the method:
$expr = Criteria::expr();
$criteria = Criteria::create();
$criteria->where($expr->gt('prize', 200));
$criteria->orderBy(['prize' => Criteria::DESC]);
$result = $purchases_repository->matching($criteria);

In some cases related with responsive layout $(document).height()
can return wrong data that displays view port height only.
For example when some div#wrapper has height:100%, that #wrapper can be stretched by some block inside it. But it's height still will be like viewport height. In such situation you might use
$('#wrapper').get(0).scrollHeight
That represents actual size of wrapper.
This works:
switch (true) {
case liCount == 0:
setLayoutState('start');
var api = $('#UploadList').data('jsp');
api.reinitialise();
break;
case liCount<=5 && liCount>0:
setLayoutState('upload1Row');
var api = $('#UploadList').data('jsp');
api.reinitialise();
break;
case liCount<=10 && liCount>5:
setLayoutState('upload2Rows');
var api = $('#UploadList').data('jsp');
api.reinitialise();
break;
case liCount>10:
var api = $('#UploadList').data('jsp');
api.reinitialise();
break;
}
A previous version of this answer considered the parentheses to be the culprit. In truth, the parentheses are irrelevant here - the only thing necessary is switch(true){...}
and for your case expressions to evaluate to booleans.
It works because, the value we give to the switch is used as the basis to compare against. Consequently, the case expressions, also evaluating to booleans will determine which case is run. Could also turn this around, and pass switch(false){..}
and have the desired expressions evaluate to false instead of true.. but personally prefer dealing with conditions that evaluate to truthyness. However, it does work too, so worth keeping in mind to understand what it is doing.
Eg: if liCount is 3, the first comparison is true === (liCount == 0)
, meaning the first case is false. The switch then moves on to the next case true === (liCount<=5 && liCount>0)
. This expression evaluates to true, meaning this case is run, and terminates at the break
. I've added parentheses here to make it clearer, but they are optional, depending on the complexity of your expression.
It's pretty simple, and a neat way (if it fits with what you are trying to do) of handling a long series of conditions, where perhaps a long series of ìf() ... else if() ... else if () ...
might introduce a lot of visual noise or fragility.
Use with caution, because it is a non-standard pattern, despite being valid code.
You can use Enumeration
:
Hashtable<Integer, String> table = ...
Enumeration<Integer> enumKey = table.keys();
while(enumKey.hasMoreElements()) {
Integer key = enumKey.nextElement();
String val = table.get(key);
if(key==0 && val.equals("0"))
table.remove(key);
}
Here's a slightly more compact solution to the problem:
const typeSizes = {
"undefined": () => 0,
"boolean": () => 4,
"number": () => 8,
"string": item => 2 * item.length,
"object": item => !item ? 0 : Object
.keys(item)
.reduce((total, key) => sizeOf(key) + sizeOf(item[key]) + total, 0)
};
const sizeOf = value => typeSizes[typeof value](value);
The other answers all use Arrays.asList()
, which returns an unmodifiable list (an UnsupportedOperationException
is thrown if you try to add or remove an element). To get a mutable list you can wrap the returned list in a new ArrayList
as a couple of answers point out, but a cleaner solution is to use Guava's Lists.newArrayList() (available since at least Guava 10, released in 2011).
For example:
Lists.newArrayList("Blargle!");

Use following command to find out default set memory limit for PHP applications.
php -r "echo ini_get('memory_limit').PHP_EOL;"
To locate active php.ini file from CLI
php -i | grep php.ini
Example:
/usr/local/lsws/lsphp73/etc/php/7.3/litespeed/php.ini
To change php.ini default value to custom:
php_memory_limit=1024M #or what ever you want it set to
sed -i 's/memory_limit = .*/memory_limit = '${php_memory_limit}'/' /usr/local/lsws/lsphp73/etc/php/7.3/litespeed/php.ini
Dont forget to restart lsws with: systemctl restart lsws
do it like this
while true
do
[ -f /tmp/list.txt ] && break
sleep 2
done
ls -l /tmp/list.txt
There is a very easy option using Visual Studio Code:
=IF(COUNTIF(A1:D1,FALSE)>0,FALSE,TRUE)
(or you can specify any other range to look in)
You're correct. Subdomains are still considered separate domains when using iframes. It's possible to pass messages using postMessage(...)
, but other JS APIs are intentionally made inaccessible.
It's also still possible to get the URL depending on the context. See other answers for more details.
This code is correct but if you entered a lot of space (' ') instead of null or empty string return false.
To correct this use regular expresion (this code below check if the variable is null or empty or blank the same as org.apache.commons.lang.StringUtils.isNotBlank) :
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
<c:if test="${not empty description}">
<c:set var="description" value="${fn:replace(description, ' ', '')}" />
<c:if test="${not empty description}">
The description is not blank.
</c:if>
</c:if>

I think most easy way is using Subject. In bellow example code the child will be notified each time 'tellChild' is called.
Parent.component.ts
import {Subject} from 'rxjs/Subject';
...
export class ParentComp {
changingValue: Subject<boolean> = new Subject();
tellChild(){
this.changingValue.next(true);
}
}
Parent.component.html
<my-comp [changing]="changingValue"></my-comp>
Child.component.ts
...
export class ChildComp implements OnInit{
@Input() changing: Subject<boolean>;
ngOnInit(){
this.changing.subscribe(v => {
console.log('value is changing', v);
});
}

Here is another way to do it:
#!/bin/bash
# Read Password
echo -n Password:
read -s password
echo
# Run Command
echo $password
The read -s
will turn off echo for you. Just replace the echo
on the last line with the command you want to run.
Yes it is, there have to be boolean expresion after IF. Here you have a direct link. I hope it helps. GL!
Assuming you have installed Android studio properly,Open a command prompt and type
emulator -list-avds
which will display all the devices and then type emulator @avd_name
where avd_name is the the name of your emulator installed.
Here is a shorter, cleaner way to get the IP address:
function get_ip_address(){
foreach (array('HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'REMOTE_ADDR') as $key){
if (array_key_exists($key, $_SERVER) === true){
foreach (explode(',', $_SERVER[$key]) as $ip){
$ip = trim($ip); // just to be safe
if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) !== false){
return $ip;
}
}
}
}
}
Your code seems to be pretty complete already, I cannot see any possible bugs in it (aside from the usual IP caveats), I would change the validate_ip()
function to rely on the filter extension though:
public function validate_ip($ip)
{
if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) === false)
{
return false;
}
self::$ip = sprintf('%u', ip2long($ip)); // you seem to want this
return true;
}
Also your HTTP_X_FORWARDED_FOR
snippet can be simplified from this:
// check for IPs passing through proxies
if (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
{
// check if multiple ips exist in var
if (strpos($_SERVER['HTTP_X_FORWARDED_FOR'], ',') !== false)
{
$iplist = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
foreach ($iplist as $ip)
{
if ($this->validate_ip($ip))
return $ip;
}
}
else
{
if ($this->validate_ip($_SERVER['HTTP_X_FORWARDED_FOR']))
return $_SERVER['HTTP_X_FORWARDED_FOR'];
}
}
To this:
// check for IPs passing through proxies
if (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
{
$iplist = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
foreach ($iplist as $ip)
{
if ($this->validate_ip($ip))
return $ip;
}
}
You may also want to validate IPv6 addresses.
There is a generic method to give CMake directions about where to find libraries.
When looking for a library, CMake looks first in the following variables:
CMAKE_LIBRARY_PATH
and LD_LIBRARY_PATH
for librariesCMAKE_INCLUDE_PATH
and INCLUDE_PATH
for includesIf you declare your Boost files in one of the environment variables, CMake will find it. Example:
export CMAKE_LIBRARY_PATH="/stuff/lib.boost.1.52/lib:$CMAKE_LIBRARY_PATH"
export CMAKE_INCLUDE_PATH="/stuff/lib.boost.1.52/include:$CMAKE_INCLUDE_PATH"
If it's too cumbersome, you can also use a nice installing tool I wrote that will do everything for you: C++ version manager
I used the Bootstrap 4 buttons plugin (https://getbootstrap.com/docs/4.0/components/buttons/#button-plugin) and added the class rounded to the labels and the class mx-1 to the middle button to achieve the desired look and feel of separate radio buttons. Using the class btn-toolbar made the radio button circles appear for me which is not what I wanted. Hope this helps someone.

In addition to the provided answers, if you want to convert Enumerable#max into a max method that can call a variable number or arguments, like in some other programming languages, you could write:
def max(*values)
values.max
end
Output:
max(7, 1234, 9, -78, 156)
=> 1234
This abuses the properties of the splat operator to create an array object containing all the arguments provided, or an empty array object if no arguments were provided. In the latter case, the method will return nil
, since calling Enumerable#max on an empty array object returns nil
.
If you want to define this method on the Math module, this should do the trick:
module Math
def self.max(*values)
values.max
end
end
Note that Enumerable.max is, at least, two times slower compared to the ternary operator (?:
). See Dave Morse's answer for a simpler and faster method.

There are over 3,047,000 records in the database. For those of you who have tried the location.module with the zipcodes database from CivicSpace, you will recognize how cool it is and how well this fits with that project and therefore Drupal.
Here's another free one that might help you get started.
Creating and maintaining such a database is quite a bit of work - so anyone who's done it is likely keeping it to themselves, or offering it for a fee.
hi you can try doing this
link_to image_tag("Search.png", border: 0), {action: 'search', controller: 'pages'}, {class: 'dock-item'}
or even
link_to image_tag("Search.png", border: 0), {action: 'search', controller: 'pages'}, class: 'dock-item'
note that the position of the curly braces is very important, because if you miss them out, rails will assume they form a single hash parameters (read more about this here)
and according to the api for link_to:
link_to(name, options = {}, html_options = nil)
hope it helps! =)
As I wrote in the edits of the op, to edit existing excel documents you must use the xlutils
module (Thanks Oliver)
Here is the proper way to do it:
#xlrd, xlutils and xlwt modules need to be installed.
#Can be done via pip install <module>
from xlrd import open_workbook
from xlutils.copy import copy
rb = open_workbook("names.xls")
wb = copy(rb)
s = wb.get_sheet(0)
s.write(0,0,'A1')
wb.save('names.xls')
This replaces the contents of the cell located at a1 in the first sheet of "names.xls" with the text "a1", and then saves the document.
For me, I had to turn off the error_reporting, to get json_decode() working correctly. It sounds weird, but true in my case. Because there is some notice printed between the JSON string that I am trying to decode.
You could set both left
and right
property to 0
. This will make the div stretch to the document width, but requires that no parent element is positioned (which is not the case, seeing as #header
is position: relative;
)
#site_nav_global_primary {
position: absolute;
top: 0;
left: 0;
right: 0;
}
Demo at: http://jsfiddle.net/xWnq2/, where I removed position:relative;
from #header
This is really simple, since OS 3.0 just set the background color of the cell in the willDisplayCell method. You must not set the color in the cellForRowAtIndexPath.
This works for both the plain and grouped style :
Code:
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
cell.backgroundColor = [UIColor redColor];
}
P.S: Here the documentation extract for willDisplayCell :
"A table view sends this message to its delegate just before it uses cell to draw a row, thereby permitting the delegate to customize the cell object before it is displayed. This method gives the delegate a chance to override state-based properties set earlier by the table view, such as selection and background color. After the delegate returns, the table view sets only the alpha and frame properties, and then only when animating rows as they slide in or out."
I've found this information in this post from colionel. Thank him!
In Kotlin you can use extension
fun Context.getMyDrawable(id : Int) : Drawable?{
return ContextCompat.getDrawable(this, id)
}
then use like
context.getMyDrawable(R.drawable.my_icon)
Boost offers a simple set of rounding functions.
#include <boost/math/special_functions/round.hpp>
double a = boost::math::round(1.5); // Yields 2.0
int b = boost::math::iround(1.5); // Yields 2 as an integer
For more information, see the Boost documentation.
Edit: Since C++11, there are std::round
, std::lround
, and std::llround
.
Take a look at "using WCF Services with PHP". It explains the basics of what you need.
As a theory summary:
WCF or Windows Communication Foundation is a technology that allow to define services abstracted from the way - the underlying communication method - they'll be invoked.
The idea is that you define a contract about what the service does and what the service offers and also define another contract about which communication method is used to actually consume the service, be it TCP, HTTP or SOAP.
You have the first part of the article here, explaining how to create a very basic WCF Service.
More resources:
Aslo take a look to NuSOAP. If you now NuSphere this is a toolkit to let you connect from PHP to an WCF service.
This is now possible with C# 7.0's pattern matching. For example:
var myString = "abcDEF";
switch(myString)
{
case string x when x.StartsWith("abc"):
//Do something here
break;
}
You have to grant the Superuser
right to the shell app (com.anroid.shell
).
In my case, I use Magisk to root my phone Nexsus 6P (Oreo 8.1). So I can grant Superuser
right in the Magisk Manager
app, whih is in the left upper option menu.
If you hava a fact png (1MB for 400x400 etc.):

The table is only dropped and re-created in cases where that's the only way SQL Server's Management Studio has been programmed to know how to do it.
There are certainly cases where it will do that when it doesn't need to, but there will also be cases where edits you make in Management Studio will not drop and re-create because it doesn't have to.
The problem is that enumerating all of the cases and determining which side of the line they fall on will be quite tedious.
This is why I like to use ALTER TABLE
in a query window, instead of visual designers that hide what they're doing (and quite frankly have bugs) - I know exactly what is going to happen, and I can prepare for cases where the only possibility is to drop and re-create the table (which is some number less than how often SSMS will do that to you).
Static data members declarations in the class declaration are not definition of them.
To define them you should do this in the .CPP
file to avoid duplicated symbols.
The only data you can declare and define is integral static constants.
(Values of enums
can be used as constant values as well)
You might want to rewrite your code as:
class test {
public:
const static unsigned char X = 1;
const static unsigned char Y = 2;
...
test();
};
test::test() {
}
If you want to have ability to modify you static variables (in other words when it is inappropriate to declare them as const), you can separate you code between .H
and .CPP
in the following way:
.H :
class test {
public:
static unsigned char X;
static unsigned char Y;
...
test();
};
.CPP :
unsigned char test::X = 1;
unsigned char test::Y = 2;
test::test()
{
// constructor is empty.
// We don't initialize static data member here,
// because static data initialization will happen on every constructor call.
}
A property is in the DOM; an attribute is in the HTML that is parsed into the DOM.
If you change an attribute, the change will be reflected in the DOM (sometimes with a different name).
Example: Changing the class
attribute of a tag will change the className
property of that tag in the DOM.
If you have no attribute on a tag, you still have the corresponding DOM property with an empty or a default value.
Example: While your tag has no class
attribute, the DOM property className
does exist with a empty string value.
edit
If you change the one, the other will be changed by a controller, and vice versa. This controller is not in jQuery, but in the browser's native code.
Add the below theme in values -> style.xml
<style name="Theme_Dialog" parent="android:Theme.Light">
<item name="android:windowNoTitle">true</item>
<item name="android:windowBackground">@android:color/transparent</item>
</style>
Use this theme in your onCreateDialog
method like this:
Dialog dialog = new Dialog(FlightBookActivity.this,R.style.Theme_Dialog);
Define your dialog layout including title bar in the xml file and set that xml file like this:
dialog.setContentView(R.layout.your_dialog_layout);
I am struggling with this problem and none of the previous answers tackle the question as I see it. I have stripped the problem back down to its basics to see if I can make my problem clear.
I create a new repository (rep1), put one file in it and commit it.
mkdir rep1
cd rep1
git init
echo "Line1" > README
git add README
git commit -m "Commit 1"
I create a clone of rep1 and call it rep2. I look inside rep2 and see the file is correct.
cd ~
git clone ~/rep1 rep2
cat ~/rep2/README
In rep1 I make a single change to the file and commit it. Then in rep1 I create a remote to point to rep2 and push the changes.
cd ~/rep1
<change file and commit>
git remote add rep2 ~/rep2
git push rep2 master
Now when I go into rep2 and do a 'git status' I get told I am ahead of origin.
# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
#
# Changes to be committed:
# (use "git reset HEAD <file>..." to unstage)
#
# modified: README
#
README in rep2 is as it was originally, before the second commit. The only modifications I have done are to rep1 and all I wanted to do was push them out to rep2. What is it I am not grasping?

For most combinations of architecture, compiler and language, <
will not be faster than <=
.
Other answers have concentrated on x86 architecture, and I don't know the ARM architecture (which your example assembler seems to be) well enough to comment specifically on the code generated, but this is an example of a micro-optimisation which is very architecture specific, and is as likely to be an anti-optimisation as it is to be an optimisation.
As such, I would suggest that this sort of micro-optimisation is an example of cargo cult programming rather than best software engineering practice.
There are probably some architectures where this is an optimisation, but I know of at least one architecture where the opposite may be true. The venerable Transputer architecture only had machine code instructions for equal to and greater than or equal to, so all comparisons had to be built from these primitives.
Even then, in almost all cases, the compiler could order the evaluation instructions in such a way that in practice, no comparison had any advantage over any other. Worst case though, it might need to add a reverse instruction (REV) to swap the top two items on the operand stack. This was a single byte instruction which took a single cycle to run, so had the smallest overhead possible.
Whether or not a micro-optimisation like this is an optimisation or an anti-optimisation depends on the specific architecture you are using, so it is usually a bad idea to get into the habit of using architecture specific micro-optimisations, otherwise you might instinctively use one when it is inappropriate to do so, and it looks like this is exactly what the book you are reading is advocating.
Sounds like you probably want a simple method like this:
public String getValueOrDefault(String value, String defaultValue) {
return isNotNullOrEmpty(value) ? value : defaultValue;
}
Then:
String result = getValueOrDefault(System.getProperty("XYZ"), "default");
At this point, you don't need temp
... you've effectively used the method parameter as a way of initializing the temporary variable.
If you really want temp
and you don't want an extra method, you can do it in one statement, but I really wouldn't:
public class Test {
public static void main(String[] args) {
String temp, result = isNotNullOrEmpty(temp = System.getProperty("XYZ")) ? temp : "default";
System.out.println("result: " + result);
System.out.println("temp: " + temp);
}
private static boolean isNotNullOrEmpty(String str) {
return str != null && !str.isEmpty();
}
}
Unfortunately if you are running on linux you cannot access the information as only the last modified date is stored.
It does slightly depend on your filesystem tho. I know that ext2 and ext3 do not support creation time but I think that ext4 does.
You probably need to set your application as an x64 app.
The IIS Snap In only works in 64 bit and doesn't work in 32 bit, and a process spawned from a 32 bit app seems to work to be a 32 bit process and the same goes for 64 bit apps.
Look at: Start process as 64 bit
The actual standard key-layout is found in /system/usr/keylayout/qwerty.kl
within the Android running on the handset. And it is a generic keylayout also.
key 115 VOLUME_UP WAKE
key 114 VOLUME_DOWN WAKE
From the AOSP source it can be found in sdk/emulator/keymaps/qwerty.kl
.
But bear in mind this, when the source gets compiled along with a device specific keylayout, that will override the standard layout instead so the mileage will vary depending on what the manufacturer has programmed into the keycode for the volume up/down buttons in your case!
To change the labels for Pandas df.plot()
use ax.legend([...])
:
import pandas as pd
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
df = pd.DataFrame({'A':26, 'B':20}, index=['N'])
df.plot(kind='bar', ax=ax)
#ax = df.plot(kind='bar') # "same" as above
ax.legend(["AAA", "BBB"]);
Another approach is to do the same by plt.legend([...])
:
import matplotlib.pyplot as plt
df.plot(kind='bar')
plt.legend(["AAA", "BBB"]);
I faced the problem in VS 2017 out of no where, took my whole day going through 100 of solutions any of these didnt work. I then took my whole solution and started it on different machine having VS 2017 installation.. IT FINALLY WORKED. Than reinstalled VS 2017 on the original one and it started running on that too. I strongly recommend you try your solution on a different machine before wasting much time to debug it, bcz it is a BUG in VS 2017 as it seemed for me, have reported same to VS TEAM. Hope this helps any one in grief. Cheers.
Your first suggestion works for me
from IPython.display import display, Image
display(Image(filename='path/to/image.jpg'))
This code was helpful in an app I'm working on:
Instant date = null;
Date sdf = null;
String formatTemplate = "EEE MMM dd yyyy HH:mm:ss";
try {
SimpleDateFormat isoFormat = new SimpleDateFormat("EEE MMM dd yyyy HH:mm:ss");
isoFormat.setTimeZone(TimeZone.getTimeZone(ZoneId.of("US/Pacific")));
sdf = isoFormat.parse(timeAtWhichToMakeAvailable);
date = sdf.toInstant();
} catch (Exception e) {
System.out.println("did not parse: " + timeAtWhichToMakeAvailable);
}
LOGGER.info("timeAtWhichToMakeAvailable: " + timeAtWhichToMakeAvailable);
LOGGER.info("sdf: " + sdf);
LOGGER.info("parsed to: " + date);
We can use RegularExpressionValidator to validate email address format. You need to specify the regular expression in ValidationExpression property of RegularExpressionValidator. So it will look like
<asp:RegularExpressionValidator ID="validateEmail"
runat="server" ErrorMessage="Invalid email."
ControlToValidate="txtEmail"
ValidationExpression="^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$" />
Also in event handler of button or link you need to check !Page.IsValid. Check sample code here : sample code
Also if you don't want to use RegularExpressionValidator you can write simple validate method and in that method usinf RegEx class of System.Text.RegularExpressions namespace.
Check example:
The plugin doesn't look very robust. If you call .placeholder()
again, it creates a new Placeholder
instance while events are still bound to the old one.
Looking at the code, it looks like you could do:
$("#serMemtb").attr("placeholder", "Type a name (Lastname, Firstname)").blur();
EDIT
placeholder
is an HTML5 attribute, guess who's not supporting it?
Your plugin doesn't really seem to help you overcome the fact that IE doesn't support it, so while my solution works, your plugin doesn't. Why don't you find one that does.
Please keep attention at this syntax:
* */6 * * *
This means 60 times (every minute) every 6 hours,
not
one time every 6 hours.
I prefers using Guava :
import com.google.common.base.Charsets;
import com.google.common.io.Files;
File file = new File("/path/to/file", Charsets.UTF_8);
String content = Files.toString(file);
If you have values in a short set of possible values then you can use something like Counting Sort
If not you have to use another data structure like a Dictionary, in java a Map
int[] array
Map<Integer, Integer>
where Key = array value for example array[i] and value = a counter
Example:
int[] array = new int [50];
Map<Integer,Integer> counterMap = new HashMap<>();
//fill the array
for(int i=0;i<array.length;i++){
if(counterMap.containsKey(array[i])){
counterMap.put(array[i], counterMap.get(array[i])+1 );
}else{
counterMap.put(array[i], 1);
}
}
Raising Matt Dowle's comment to Geneorama's answer (https://stackoverflow.com/a/20808945/4241780) to make it more obvious (as encouraged), you can use for(...)set(...)
.
library(data.table)
DT = data.table(a = LETTERS[c(3L,1:3)], b = 4:7, c = letters[1:4])
DT1 <- copy(DT)
names_factors <- c("a", "c")
for(col in names_factors)
set(DT, j = col, value = as.factor(DT[[col]]))
sapply(DT, class)
#> a b c
#> "factor" "integer" "factor"
Created on 2020-02-12 by the reprex package (v0.3.0)
See another of Matt's comments at https://stackoverflow.com/a/33000778/4241780 for more info.
Edit.
As noted by Espen and in help(set)
, j
may be "Column name(s) (character) or number(s) (integer) to be assigned value when column(s) already exist". So names_factors <- c(1L, 3L)
will also work.
If both the list are too big and when we use lamda expression then it will take a long time to fetch . Better to use linq in this case to fetch parameters list:
var items = (from x in parameters
join y in myStrings on x.Source equals y
select x)
.ToList();
For optimal Insertion performance disable the index if that's an option for you. Other than that, better hardware (disk, memory) is also helpful
You can find out what library depends on a wrong version of the support library and exclude it like this:
compile ('com.stripe:stripe-android:5.1.1') {
exclude group: 'com.android.support'
}
stripe-android
in my case.
For rows, try this, where Name
is the joint index column (can be a list for multiple common columns, or specify left_on
and right_on
):
m = df1.merge(df2, on='Name', how='outer', suffixes=['', '_'], indicator=True)
The indicator=True
setting is useful as it adds a column called _merge
, with all changes between df1
and df2
, categorized into 3 possible kinds: "left_only", "right_only" or "both".
For columns, try this:
set(df1.columns).symmetric_difference(df2.columns)
You can simply change the name of the file by changing the name of the file in the second parameter of move_uploaded_file
.
Instead of
move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $_FILES["file"]["name"]);
Use
$temp = explode(".", $_FILES["file"]["name"]);
$newfilename = round(microtime(true)) . '.' . end($temp);
move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $newfilename);
Changed to reflect your question, will product a random number based on the current time and append the extension from the originally uploaded file.
Try one of these approaches:
Approach 1)
1- Choose project view
2- Copy your JAR file in app -> lib folder
3- Right click on your JAR file and choose add as library
4- Check it in build.gradle
Approach 2)
1- File -> New -> New Module
2- Import .JAR/.AAR Package
3- Browse your JAR File
4- Finish
5- File -> Project Structure -> Dependencies
6- You should click on + button and then click on Module Dependency
7- You will see your library here
8- choose your library and click ok
9- Then, you will see that your library is added.
For first two approaches, you need a JAR file. You can search http://search.maven.org/ to find JAR files that are related to Android. For example, this is the search result for jdom in this link
Approach 3) Android is using http://jcenter.bintray.com/ as remote library. For example, this is the search result for jdom in the link.
To add a library in this approach, please follow these steps:
1- File -> Project Structure -> Dependencies
2- Click on + button and choose library dependency
3- find your library and select it, then click OK.
I hope it helps.
Your file should directly be under the project folder, and not inside any other sub-folder.
If the folder of your project is named for e.g. AProject
, it should be in the same place as your src
folder.
Aproject
src
word.txt
Some people are saying it's not possible of downloading files with a batch script without using any JScript or VBScript, etc... But they are definitely wrong!
Here is a simple method that seems to work pretty well for downloading files in your batch scripts. It should be working on almost any file's URL. It is even possible to use a proxy server if you need it.
For downloading files, we can use BITSADMIN.EXE from the Windows system. There is no need for downloading/installing anything or using any JScript or VBScript, etc. Bitsadmin.exe is present on most Windows versions, probably from XP to Windows 10.
Enjoy!
USAGE:
You can use the BITSADMIN command directly, like this:
bitsadmin /transfer mydownloadjob /download /priority FOREGROUND "http://example.com/File.zip" "C:\Downloads\File.zip"
Proxy Server:
For connecting using a proxy, use this command before downloading.
bitsadmin /setproxysettings mydownloadjob OVERRIDE "proxy-server.com:8080"
Click this LINK if you want more info about BITSadmin.exe
TROUBLESHOOTING:
If you get this error: "Unable to connect to BITS - 0x80070422"
Make sure the windows service "Background Intelligent Transfer Service (BITS)" is enabled and try again. (It should be enabled by default.)
CUSTOM FUNCTIONS
Call :DOWNLOAD_FILE "URL"
Call :DOWNLOAD_PROXY_ON "SERVER:PORT"
Call :DOWNLOAD_PROXY_OFF
I made these 3 functions for simplifying the bitsadmin commands. It's easier to use and remember. It can be particularly useful if you are using it multiple times in your scripts.
PLEASE NOTE...
Before using these functions, you will first need to copy them from CUSTOM_FUNCTIONS.CMD to the end of your script. There is also a complete example: DOWNLOAD-EXAMPLE.CMD
:DOWNLOAD_FILE "URL"
The main function, will download files from URL.
:DOWNLOAD_PROXY_ON "SERVER:PORT"
(Optional) You can use this function if you need to use a proxy server.
Calling the :DOWNLOAD_PROXY_OFF function will disable the proxy server.
EXAMPLE:
CALL :DOWNLOAD_PROXY_ON "proxy-server.com:8080"
CALL :DOWNLOAD_FILE "http://example.com/File.zip" "C:\Downloads\File.zip"
CALL :DOWNLOAD_PROXY_OFF

If you want to call a function on clicking of submit button then you have
to use ajax or jquery,if you want to call your php function after submission of form
you can do that as :
<html>
<body>
<form method="post" action="display()">
<input type="text" name="studentname">
<input type="submit" value="click">
</form>
<?php
function display()
{
echo "hello".$_POST["studentname"];
}
if($_SERVER['REQUEST_METHOD']=='POST')
{
display();
}
?>
</body>
</html>
INSERT INTO AM_PROGRAM_TUNING_EVENT_TMP1
VALUES(TO_DATE('2012-03-28 11:10:00','yyyy/mm/dd hh24:mi:ss'));
Put this in /etc/init
(Use /etc/systemd
in Ubuntu 15.x)
mystartupscript.conf
start on runlevel [2345]
stop on runlevel [!2345]
exec /path/to/script.py
By placing this conf file there you hook into ubuntu's upstart service that runs services on startup.
manual starting/stopping is done with
sudo service mystartupscript start
and
sudo service mystartupscript stop
I was using Eclipse Juno and I didn't remember if it was 32 or 64 bits. I installed Java 32 bits and that's why it failed. I then installed Java 64 bits and Eclipse Juno is working again.
I also removed any java or jre reference in my environment variables (PATH).

If you are using moment.js then it is pretty simple to find date difference.
var now = "04/09/2013 15:00:00";
var then = "04/09/2013 14:20:30";
moment.utc(moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"))).format("HH:mm:ss")
Now you can use just window.scrollTo({ top: 0, behavior: 'smooth' })
to get the page scrolled with a smooth effect.
const btn = document.getElementById('elem');_x000D_
_x000D_
btn.addEventListener('click', () => window.scrollTo({_x000D_
top: 400,_x000D_
behavior: 'smooth',_x000D_
}));
_x000D_
#x {_x000D_
height: 1000px;_x000D_

}
_x000D_
<div id='x'>_x000D_
<button id='elem'>Click to scroll</button>_x000D_
</div>
_x000D_
You can do something like this:
var btn = document.getElementById('x');_x000D_
_x000D_
btn.addEventListener("click", function() {_x000D_
var i = 10;_x000D_
var int = setInterval(function() {_x000D_
window.scrollTo(0, i);_x000D_
i += 10;_x000D_

I've came up with a "responsive" solution for fullscreen modals:
Fullscreen Modals that can be enabled only on certain breakpoints. In this way the modal will display "normal" on wider (desktop) screens and fullscreen on smaller (tablet or mobile) screens, giving it the feeling of a native app.
Implemented for Bootstrap 3 and Bootstrap 4. Included by default in Bootstrap 5.
Fullscreen modals are included by default in Bootstrap 5: https://getbootstrap.com/docs/5.0/components/modal/#fullscreen-modal
The following generic code should work:
.modal {
padding: 0 !important; // override inline padding-right added from js
}
.modal .modal-dialog {
width: 100%;
max-width: none;
height: 100%;
margin: 0;
}
.modal .modal-content {
height: 100%;
border: 0;
border-radius: 0;
}
.modal .modal-body {
overflow-y: auto;
}
By including the scss code below, it generates the following classes that need to be added to the .modal
element:
+---------------+---------+---------+---------+---------+---------+
| | xs | sm | md | lg | xl |
| | <576px | =576px | =768px | =992px | =1200px |
+---------------+---------+---------+---------+---------+---------+
|.fullscreen | 100% | default | default | default | default |
+---------------+---------+---------+---------+---------+---------+
|.fullscreen-sm | 100% | 100% | default | default | default |
+---------------+---------+---------+---------+---------+---------+
|.fullscreen-md | 100% | 100% | 100% | default | default |
+---------------+---------+---------+---------+---------+---------+
|.fullscreen-lg | 100% | 100% | 100% | 100% | default |
+---------------+---------+---------+---------+---------+---------+
|.fullscreen-xl | 100% | 100% | 100% | 100% | 100% |
+---------------+---------+---------+---------+---------+---------+
The scss code is:
@mixin modal-fullscreen() {
padding: 0 !important; // override inline padding-right added from js
.modal-dialog {
width: 100%;
max-width: none;
height: 100%;
margin: 0;
}
.modal-content {
height: 100%;
border: 0;
border-radius: 0;
}
.modal-body {
overflow-y: auto;
}
}
@each $breakpoint in map-keys($grid-breakpoints) {
@include media-breakpoint-down($breakpoint) {
$infix: breakpoint-infix($breakpoint, $grid-breakpoints);
.modal-fullscreen#{$infix} {
@include modal-fullscreen();
}
}
}

Based on previous responses to this topic (@Chris J, @kkarli), the following generic code should work:
.modal {
padding: 0 !important; // override inline padding-right added from js
}
.modal .modal-dialog {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
}
.modal .modal-content {
height: auto;
min-height: 100%;
border: 0 none;
border-radius: 0;
box-shadow: none;
}
If you want to use responsive fullscreen modals, use the following classes that need to be added to .modal
element:
.modal-fullscreen-md-down
- the modal is fullscreen for screens smaller than 1200px
..modal-fullscreen-sm-down
- the modal is fullscreen for screens smaller than 922px
..modal-fullscreen-xs-down
- the modal is fullscreen for screen smaller than 768px
.Take a look at the following code:
/* Extra small devices (less than 768px) */
@media (max-width: 767px) {
.modal-fullscreen-xs-down {
padding: 0 !important;
}
.modal-fullscreen-xs-down .modal-dialog {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
}
.modal-fullscreen-xs-down .modal-content {
height: auto;
min-height: 100%;
border: 0 none;
border-radius: 0;
box-shadow: none;
}
}
/* Small devices (less than 992px) */
@media (max-width: 991px) {
.modal-fullscreen-sm-down {
padding: 0 !important;
}
.modal-fullscreen-sm-down .modal-dialog {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
}
.modal-fullscreen-sm-down .modal-content {
height: auto;
min-height: 100%;
border: 0 none;
border-radius: 0;
box-shadow: none;
}
}
/* Medium devices (less than 1200px) */
@media (max-width: 1199px) {
.modal-fullscreen-md-down {
padding: 0 !important;
}
.modal-fullscreen-md-down .modal-dialog {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
}
.modal-fullscreen-md-down .modal-content {
height: auto;
min-height: 100%;
border: 0 none;
border-radius: 0;
box-shadow: none;
}
}

Those who use Sass as a preprocessor can take advantage of the following mixin:
@mixin modal-fullscreen() {
padding: 0 !important; // override inline padding-right added from js
.modal-dialog {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
}
.modal-content {
height: auto;
min-height: 100%;
border: 0 none;
border-radius: 0;
box-shadow: none;
}
}
I recently just figured out how to do this, and here's some example code from a current project of mine:
#Getting the random picture.
#First find all pictures:
import shlex, subprocess
cmd = 'find ../Pictures/ -regex ".*\(JPG\|NEF\|jpg\)" '
#cmd = raw_input("shell:")
args = shlex.split(cmd)
output,error = subprocess.Popen(args,stdout = subprocess.PIPE, stderr= subprocess.PIPE).communicate()
#Another way to get output
#output = subprocess.Popen(args,stdout = subprocess.PIPE).stdout
ber = raw_input("search complete, display results?")
print output
#... and on to the selection process ...
You now have the output of the command stored in the variable "output". "stdout = subprocess.PIPE" tells the class to create a file object named 'stdout' from within Popen. The communicate() method, from what I can tell, just acts as a convenient way to return a tuple of the output and the errors from the process you've run. Also, the process is run when instantiating Popen.
I don't know if this will help you but..
NorthwindDataContext dc = new NorthwindDataContext();
dc.Log = Console.Out;
var query =
from c in dc.Customers
where !(from o in dc.Orders
select o.CustomerID)
.Contains(c.CustomerID)
select c;
foreach (var c in query) Console.WriteLine( c );
To hide arrows and cross in a "time" input :
#inputId::-webkit-outer-spin-button,
#inputId::-webkit-inner-spin-button,
#inputId::-webkit-clear-button{
-webkit-appearance: none;
margin: 0;
}
After all above step clean and Rebuild is also a factor.
I used this to create a toggle effect between two functions.
var x = false;
$(element).on('click', function(){
if (!x){
//function
x = true;
}
else {
//function
x = false;
}
});
function isValidUSZip(sZip) {
return /^\d{5}(-\d{4})?$/.test(sZip);
}
The problem is that when you are doing additions and multiplications of numbers all with two decimal places, you expect there will be no rounding errors, but remember the internal representation of double is in base 2, not in base 10 ! So a number like 0.1 in base 10 may be in base 2 : 0.101010101010110011... with an infinite number of decimals (the value stored in the double will be a number N with :
0.1-Math.Pow(2,-64) < N < 0.1+Math.Pow(2,-64)
As a consequence an operation like 12.3 + 0.1 may be not the same exact 64 bits double value as 12.4 (or 12.456 * 10 may be not the same as 124.56) because of rounding errors. For example if you store in a Database the result of 12.3 +0.1 into a table/column field of type double precision number and then SELECT WHERE xx=12.4 you may realize that you stored a number that is not exactly 12.4 and the Sql select will not return the record; So if you cannot use the decimal datatype (which has internal representation in base 10) and must use the 'double' datatype, you have to do some normalization after each addition or multiplication :
double freqMHz= freqkHz.MulRound(0.001); // freqkHz*0.001
double amountEuro= amountEuro.AddRound(delta); // amountEuro+delta
public static double AddRound(this double d,double val)
{
return double.Parse(string.Format("{0:g14}", d+val));
}
public static double MulRound(this double d,double val)
{
return double.Parse(string.Format("{0:g14}", d*val));
}
Why don't you just stash the vbscript in a batch/vbscript file hybrid. Name the batch hybrid Converter.bat and you can execute it directly as Converter from the cmd line. Sure you can default ALL scripts to run from Cscript or Wscript, but if you want to execute your vbs as a windows script rather than a console script, this could cause some confusion later on. So just set your code to a batch file and run it directly.
Check the answer -> Here
And here is an example:
Converter.bat
::' VBS/Batch Hybrid
::' --- Batch portion ---------
rem^ &@echo off
rem^ &call :'sub
rem^ &exit /b
:'sub
rem^ &echo begin batch
rem^ &cscript //nologo //e:vbscript "%~f0"
rem^ &echo end batch
rem^ &exit /b

Here's a simple function that serves to explain the usage:
def print_wrap(arg1, *args, **kwargs):
print(arg1)
print(args)
print(kwargs)
print(arg1, *args, **kwargs)
Any arguments that are not specified in the function definition will be put in the args
list, or the kwargs
list, depending on whether they are keyword arguments or not:
>>> print_wrap('one', 'two', 'three', end='blah', sep='--')
one
('two', 'three')
{'end': 'blah', 'sep': '--'}
one--two--threeblah
If you add a keyword argument that never gets passed to a function, an error will be raised:
>>> print_wrap('blah', dead_arg='anything')
TypeError: 'dead_arg' is an invalid keyword argument for this function
Though I am late to answer this, a better approach to get distinct records using Eloquent would be
$user_names = User::distinct()->get(['name']);
The solution that i believe is best and optimized is:
try: #your code except "ModelName".DoesNotExist: #your code
If you just want to get your HDFS back to normal state and don't worry much about the data, then
This will list the corrupt HDFS blocks:
hdfs fsck -list-corruptfileblocks
This will delete the corrupted HDFS blocks:
hdfs fsck / -delete
Note that, you might have to use sudo -u hdfs
if you are not the sudo user (assuming "hdfs" is name of the sudo user)
I assume you need to save couchdb-cartridge
which has an image id of 7ebc8510bc2c:
stratos@Dev-PC:~$ docker images

ubuntu 14.04 53bf7a53e890 3 days ago 221.3 MB
Save the archiveName image to a tar file. I will use the /media/sf_docker_vm/
to save the image.
stratos@Dev-PC:~$ docker save imageID > /media/sf_docker_vm/archiveName.tar
Copy the archiveName.tar file to your new Docker instance using whatever method works in your environment, for example FTP
, SCP
, etc.
Run the docker load
command on your new Docker instance and specify the location of the image tar file.
stratos@Dev-PC:~$ docker load < /media/sf_docker_vm/archiveName.tar
Finally, run the docker images
command to check that the image is now available.

Please find this detailed post.
You need to get hold of the axes themselves. Probably the cleanest way is to change your last row:
lm = sns.lmplot('X','Y',df,col='Z',sharex=False,sharey=False)
Then you can get hold of the axes objects (an array of axes):
axes = lm.axes
After that you can tweak the axes properties
axes[0,0].set_ylim(0,)
axes[0,1].set_ylim(0,)

A solution i'd go with that's fine for 32-bits, is the code the end of this answer, which is from developer.mozilla.org(MDN), but with some lines added for A)formatting and B)checking that the number is in range.
Some suggested x.toString(2)
which doesn't work for negatives, it just sticks a minus sign in there for them, which is no good.
Fernando mentioned a simple solution of (x>>>0).toString(2);
which is fine for negatives, but has a slight issue when x is positive. It has the output starting with 1, which for positive numbers isn't proper 2s complement.
Anybody that doesn't understand the fact of positive numbers starting with 0 and negative numbers with 1, in 2s complement, could check this SO QnA on 2s complement. What is “2's Complement”?
A solution could involve prepending a 0 for positive numbers, which I did in an earlier revision of this answer. And one could accept sometimes having a 33bit number, or one could make sure that the number to convert is within range -(2^31)<=x<2^31-1. So the number is always 32bits. But rather than do that, you can go with this solution on mozilla.org
Patrick's answer and code is long and apparently works for 64-bit, but had a bug that a commenter found, and the commenter fixed patrick's bug, but patrick has some "magic number" in his code that he didn't comment about and has forgotten about and patrick no longer fully understands his own code / why it works.
Annan had some incorrect and unclear terminology but mentioned a solution by developer.mozilla.org https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Bitwise_Operators This works for 32-bit numbers.
The code is pretty compact, a function of three lines.
But I have added a regex to format the output in groups of 8 bits. Based on How to print a number with commas as thousands separators in JavaScript (I just amended it from grouping it in 3s right to left and adding commas, to grouping in 8s right to left, and adding spaces)
And, while mozilla made a comment about the size of nMask(the number fed in)..that it has to be in range, they didn't test for or throw an error when the number is out of range, so i've added that.
I'm not sure why they named their parameter 'nMask' but i'll leave that as is.

Don't do: mkdir -m 777 -p a/b/c
since that will only set permission 777
on the last directory, c; a and b will be created with the default permission from your umask.
Instead to create any new directories with permission 777
, run mkdir -p
in a subshell where you override the umask:
(umask u=rwx,g=rwx,o=rwx && mkdir -p a/b/c)
Note that this won't change the permissions if any of a, b and c already exist though.
For simple integer arithmetic, you can also use the builtin let command.
ONE=1
TWO=2
let "THREE = $ONE + $TWO"
echo $THREE
3
For more info on let
, look here.
To add to what people have said about from x import *
: besides making it more difficult to tell where names came from, this throws off code checkers like Pylint. They will report those names as undefined variables.
