To add one more important information to above provided answers -
For a process
def proc = command.execute();
always try to use
def outputStream = new StringBuffer();
proc.waitForProcessOutput(outputStream, System.err)
//proc.waitForProcessOutput(System.out, System.err)
rather than
def output = proc.in.text;
to capture the outputs after executing commands in groovy as the latter is a blocking call (SO question for reason).
Make sure your AUTO_INCREMENT
is not out of range. In that case, set a new value for it with:
ALTER TABLE table_name AUTO_INCREMENT=100 -- Change 100 to the desired number
AUTO_INCREMENT
can contain a number that is bigger than the maximum value allowed by the datatype. This can happen if you filled up a table that you emptied afterward but the AUTO_INCREMENT
stayed the same, but there might be different reasons as well. In this case a new entry's id would be out of range.
If this is the cause of your problem, you can fix it by setting AUTO_INCREMENT
to one bigger than the latest row's id. So if your latest row's id is 100 then:
ALTER TABLE table_name AUTO_INCREMENT=101
If you would like to check AUTO_INCREMENT
's current value, use this command:
SELECT `AUTO_INCREMENT`
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = 'DatabaseName'
AND TABLE_NAME = 'TableName';

After looking into many answers (most of them are correct for their scenarios) and none of them fix my problem I realized that my case is a bit different:
In my weird scenario my component was being rendered inside the state and therefore couldn't be updated. Below is a simple example:
constructor() {
this.myMethod = this.myMethod.bind(this);
this.changeTitle = this.changeTitle.bind(this);
this.myMethod();
}
changeTitle() {
this.setState({title: 'I will never get updated!!'});
}
myMethod() {
this.setState({body: <div>{this.state.title}</div>});
}
render() {
return <>
{this.state.body}
<Button onclick={() => this.changeTitle()}>Change Title!</Button>
</>
}
After refactoring the code to not render the body from state it worked fine :)
This can be done with a regular expression replacer function I posted in another answer and have blogged about here. It may not be the most efficient solution possible and might look overkill for the job in hand - but like a Swiss army knife, it may come in useful for other reasons.
It can be seen in action removing all non-alphanumeric characters in this Rextester online demo.
SQL (excluding the function code for brevity):
SELECT txt,
reg_replace(txt,
'[^a-zA-Z0-9]+',
'',
TRUE,
0,
0
) AS `reg_replaced`
FROM test;
I ran into a problem with this as well as my JUnit assertEquals were failing comparing Dates to Hibernate emitted 'java.util.Date' types (which as described in the question are really Timestamps). It turns out that by changing the mapping to 'date' rather than 'java.util.Date' Hibernate generates java.util.Date members. I am using an XML mapping file with Hibernate version 4.1.12.
This version emits 'java.util.Timestamp':
<property name="date" column="DAY" type="java.util.Date" unique-key="KONSTRAINT_DATE_IDX" unique="false" not-null="true" />
This version emits 'java.util.Date':
<property name="date" column="DAY" type="date" unique-key="KONSTRAINT_DATE_IDX" unique="false" not-null="true" />
Note, however, if Hibernate is used to generate the DDL, then these will generate different SQL types (Date for 'date' and Timestamp for 'java.util.Date').
The one-liner version in Python:
$ python -c "import sys; print(sum(int(l) for l in sys.stdin))"
You could use val()
.
var value = $('#area1').val();
$('#VAL_DISPLAY').html(value);
Try the sp_foreachdb procedure.
System.currentTimeMillis()
is obviously the fastest because it's only one method call and no garbage collector is required.
java.util.Date date = ...
DateTime dateTime = new DateTime(date);
Make sure date
isn't null
, though, otherwise it acts like new DateTime()
- I really don't like that.
I like Chaosmaster's solution! But I looked for a solution which does not start another external program (like find.exe or findstr.exe). So I added the idea from Matt Lacey's solution, which creates an also avoidable temp file. At the end I could find a fairly simple solution, so I share it...
SETLOCAL EnableExtensions
set EXE=myprog.exe
FOR /F %%x IN ('tasklist /NH /FI "IMAGENAME eq %EXE%"') DO IF %%x == %EXE% goto FOUND
echo Not running
goto FIN
:FOUND
echo Running
:FIN
This is working for me nicely...
You can use the v$session_connect_info
view against the current session ID (SID
from the USERENV
namespace in SYS_CONTEXT
).
e.g.
SELECT
DISTINCT
s.client_version
FROM
v$session_connect_info s
WHERE
s.sid = SYS_CONTEXT('USERENV', 'SID');
There aren't any quotes. It's just VS debugger. Try printing to the console or saving to a file and you'll see. As a side note: always dispose disposable objects:
using (var stringWriter = new StringWriter())
using (var xmlTextWriter = XmlWriter.Create(stringWriter))
{
xmlDoc.WriteTo(xmlTextWriter);
xmlTextWriter.Flush();
return stringWriter.GetStringBuilder().ToString();
}
I stumbled on this question as I had the same error. Mine was due to a slightly different problem and since I resolved it on my own I thought it useful to share here. Original code with issue:
$comment = "$_POST['comment']";
Because of the enclosing double-quotes, the index is not dereferenced properly leading to the assignment error. In my case I chose to fix it like this:
$comment = "$_POST[comment]";
but dropping either pair of quotes works; it's a matter of style I suppose :)
Continuing the evolution of this solution I've upped the ante by adding support for multiple root selections and deeper nested selections. This is a further development of JavierCane's solution (which in turn built on tarheel's).

As Javier says:
And if you wanted to see it in action I've created a demo sheet and you can see the code if you take a copy.
The best solution is my method:
In my method, only full words are detected,But in other ways it is not.
for example:
$text='hello world!';
if(strpos($text, 'wor') === FALSE) {
echo '"wor" not found in string';
}
Result: strpos returned true
!!! but in my method return false
.
My method:
public function searchInLine($txt,$word){
$txt=strtolower($txt);
$word=strtolower($word);
$word_length=strlen($word);
$string_length=strlen($txt);
if(strpos($txt,$word)!==false){
$indx=strpos($txt,$word);
$last_word=$indx+$word_length;
if($indx==0){
if(strpos($txt,$word." ")!==false){
return true;
}
if(strpos($txt,$word.".")!==false){
return true;
}
if(strpos($txt,$word.",")!==false){
return true;
}
if(strpos($txt,$word."?")!==false){
return true;
}
if(strpos($txt,$word."!")!==false){
return true;
}
}else if($last_word==$string_length){
if(strpos($txt," ".$word)!==false){
return true;
}
if(strpos($txt,".".$word)!==false){
return true;
}
if(strpos($txt,",".$word)!==false){
return true;
}
if(strpos($txt,"?".$word)!==false){
return true;
}
if(strpos($txt,"!".$word)!==false){
return true;
}
}else{
if(strpos($txt," ".$word." ")!==false){
return true;
}
if(strpos($txt," ".$word.".")!==false){
return true;
}
if(strpos($txt," ".$word.",")!==false){
return true;
}
if(strpos($txt," ".$word."!")!==false){
return true;
}
if(strpos($txt," ".$word."?")!==false){
return true;
}
}
}
return false;
}
if you don't want add the attr disabled can do it programmatically
can disable the edition into the <select class="yourClass">
element with this code:
//bloqueo selects
//block all selects
jQuery(document).on("focusin", 'select.yourClass', function (event) {
var $selectDiabled = jQuery(this).attr('disabled', 'disabled');
setTimeout(function(){ $selectDiabled.removeAttr("disabled"); }, 30);
});

pipenv want combine all, in addition to previous it installs "requirements" (into the active virtual environment or create its own if none is active)
So maybe you will be happy with pipenv only.
But I use: pyenv + pyenv-virtualenvwrapper, + pipenv (pipenv for installing requirements only).
In Debian:
apt install libffi-dev
install pyenv based on https://www.tecmint.com/pyenv-install-and-manage-multiple-python-versions-in-linux/, but..
.. but instead of pyenv-virtualenv install pyenv-virtualenvwrapper (which can be standalone library or pyenv plugin, here the 2nd option):
pyenv install 3.9.0
git clone https://github.com/pyenv/pyenv-virtualenvwrapper.git $(pyenv root)/plugins/pyenv-virtualenvwrapper
into ~/.bashrc add: export $VIRTUALENVWRAPPER_PYTHON="/usr/bin/python3"
source ~/.bashrc
pyenv virtualenvwrapper
Then create virtual environments for your projects (workingdir must exist):
pyenv local 3.9.0 # to prevent 'interpreter not found' in mkvirtualenv
python -m pip install --upgrade pip setuptools wheel
mkvirtualenv <venvname> -p python3.9 -a <workingdir>
and switch between projects:
workon <venvname>
python -m pip install --upgrade pip setuptools wheel pipenv
Inside a project I have the file requirements.txt, without fixing the versions inside (if some version limitation is not neccessary). You have 2 possible tools to install them into the current virtual environment: pip-tools or pipenv. Lets say you will use pipenv:
pipenv install -r requirements.txt
this will create Pipfile and Pipfile.lock files, fixed versions are in the 2nd one. If you want reinstall somewhere exactly same versions then (Pipfile.lock must be present):
pipenv install
Remember that Pipfile.lock is related to some Python version and need to be recreated if you use a different one.
As you see I write requirements.txt. This has some problems: You must remove a removed package from Pipfile too. So writing Pipfile directly is probably better.
So you can see I use pipenv very poorly. Maybe if you will use it well, it can replace everything?
EDIT 2021.01: I have changed my stack to: pyenv + pyenv-virtualenvwrapper + poetry
. Ie. I use no apt or pip installation of virtualenv or virtualenvwrapper, and instead I install pyenv
's plugin pyenv-virtualenvwrapper
. This is easier way.
Poetry
is great for me:
poetry add <package> # install single package
poetry remove <package>
poetry install # if you remove poetry.lock poetry will re-calculate versions
In my use case we had a similar need for CI CD. We used git flow with develop and master branches. Developers are free to merge their changes directly to develop or via a pull request from a feature branch. However to master we merge only the stable commits from the develop branch in an automated way via Jenkins.
In this case doing cherry-pick is not a good option. However we create a local-branch from the commit-id then merge that local-branch to master and perform mvn clean verify(we use maven). If success then release production version artifact to nexus using maven release plugin with localCheckout=true option and pushChanges=false. Finally when everything is success then push the changes and tag to origin.
A sample code snippet:
Assuming you are on master if done manually. However on jenkins, when you checkout the repo you will be on the default branch(master if configured).
git pull // Just to pull any changes.
git branch local-<commitd-id> <commit-id> // Create a branch from the given commit-id
git merge local-<commit-id> // Merge that local branch to master.
mvn clean verify // Verify if the code is build able
mvn <any args> release:clean release:prepare release:perform // Release artifacts
git push origin/master // Push the local changes performed above to origin.
git push origin <tag> // Push the tag to origin
This will give you a full control with a fearless merge or conflict hell.
Feel free to advise in case there is any better option.
The references in a website project are stored in its web.config file. Update the reference there to fix the error.
I spent some time looking at all the references in my solution before realizing that I had forgotten about the references in the web.config file.
by VB function:
Dim m_RowNr(3) as Variant
'
Function RowNr(ByVal strQName As String, ByVal vUniqValue) As Long
' m_RowNr(3)
' 0 - Nr
' 1 - Query Name
' 2 - last date_time
' 3 - UniqValue
If Not m_RowNr(1) = strQName Then
m_RowNr(0) = 1
m_RowNr(1) = strQName
ElseIf DateDiff("s", m_RowNr(2), Now) > 9 Then
m_RowNr(0) = 1
ElseIf Not m_RowNr(3) = vUniqValue Then
m_RowNr(0) = m_RowNr(0) + 1
End If
m_RowNr(2) = Now
m_RowNr(3) = vUniqValue
RowNr = m_RowNr(0)
End Function
Usage(without sorting option):
SELECT RowNr('title_of_query_or_any_unique_text',A.id) as Nr,A.*
From table A
Order By A.id
if sorting required or multiple tables join then create intermediate table:
SELECT RowNr('title_of_query_or_any_unique_text',A.id) as Nr,A.*
INTO table_with_Nr
From table A
Order By A.id
The other offical way would be using git bundle
That will create a file that support git fetch
and git pull
in order to update your second repo.
Useful for incremental backup and restore.
But if you need to backup everything (because you do not have a second repo with some older content already in place), the backup is a bit more elaborate to do, as mentioned in my other answer, after Kent Fredric's comment:
$ git bundle create /tmp/foo master
$ git bundle create /tmp/foo-all --all
$ git bundle list-heads /tmp/foo
$ git bundle list-heads /tmp/foo-all
(It is an atomic operation, as opposed to making an archive from the .git
folder, as commented by fantabolous)
Warning: I wouldn't recommend Pat Notz's solution, which is cloning the repo.
Backup many files is always more tricky than backing up or updating... just one.
If you look at the history of edits of the OP Yar answer, you would see that Yar used at first a clone --mirror
, ... with the edit:
Using this with Dropbox is a total mess.
You will have sync errors, and you CANNOT ROLL A DIRECTORY BACK IN DROPBOX.
Usegit bundle
if you want to back up to your dropbox.
Yar's current solution uses git bundle
.
I rest my case.
A quick Google search got this (from http://www.codecodex.com/wiki/index.php?title=Count_the_number_of_occurrences_of_a_specific_character_in_a_string#JavaScript)
String.prototype.count=function(s1) {
return (this.length - this.replace(new RegExp(s1,"g"), '').length) / s1.length;
}
Use it like this:
test = 'one,two,three,four'
commas = test.count(',') // returns 3
Don't use a service for this. Create a normal application and create a scheduled task to run it.
This is the commonly held best practice. Jon Galloway agrees with me. Or maybe its the other way around. Either way, the fact is that it is not best practices to create a windows service to perform an intermittent task run off a timer.

Use
Model.created_at.strftime("%FT%T")
where,
%F - The ISO 8601 date format (%Y-%m-%d)
%T - 24-hour time (%H:%M:%S)
Following are some of the frequently used useful list of Date
and Time
formats that you could specify in strftime
method:
Date (Year, Month, Day):
%Y - Year with century (can be negative, 4 digits at least)
-0001, 0000, 1995, 2009, 14292, etc.
%C - year / 100 (round down. 20 in 2009)
%y - year % 100 (00..99)
%m - Month of the year, zero-padded (01..12)
%_m blank-padded ( 1..12)
%-m no-padded (1..12)
%B - The full month name (``January'')
%^B uppercased (``JANUARY'')
%b - The abbreviated month name (``Jan'')
%^b uppercased (``JAN'')
%h - Equivalent to %b
%d - Day of the month, zero-padded (01..31)
%-d no-padded (1..31)
%e - Day of the month, blank-padded ( 1..31)
%j - Day of the year (001..366)
Time (Hour, Minute, Second, Subsecond):
%H - Hour of the day, 24-hour clock, zero-padded (00..23)
%k - Hour of the day, 24-hour clock, blank-padded ( 0..23)
%I - Hour of the day, 12-hour clock, zero-padded (01..12)
%l - Hour of the day, 12-hour clock, blank-padded ( 1..12)
%P - Meridian indicator, lowercase (``am'' or ``pm'')
%p - Meridian indicator, uppercase (``AM'' or ``PM'')
%M - Minute of the hour (00..59)
%S - Second of the minute (00..59)
%L - Millisecond of the second (000..999)
%N - Fractional seconds digits, default is 9 digits (nanosecond)

I use the DataGridView's Invalidate()
function. However, that will refresh the entire DataGridView. If you want to refresh a particular row, you use dgv.InvalidateRow(rowIndex)
. If you want to refresh a particular cell, you can use dgv.InvalidateCell(columnIndex, rowIndex)
. This is of course assuming you're using a binding source or data source.
First of all: I'm the author of the The Single Page Interface Manifesto cited by raganwald
As raganwald has explained very well, the most important aspect of the Single Page Interface (SPI) approach used in FaceBook and Twitter is the use of hash #
in URLs
The character !
is added only for Google purposes, this notation is a Google "standard" for crawling web sites intensive on AJAX (in the extreme Single Page Interface web sites). When Google's crawler finds an URL with #!
it knows that an alternative conventional URL exists providing the same page "state" but in this case on load time.
In spite of #!
combination is very interesting for SEO, is only supported by Google (as far I know), with some JavaScript tricks you can build SPI web sites SEO compatible for any web crawler (Yahoo, Bing...).
The SPI Manifesto and demos do not use Google's format of !
in hashes, this notation could be easily added and SPI crawling could be even easier (UPDATE: now ! notation is used and remains compatible with other search engines).
Take a look to this tutorial, is an example of a simple ItsNat SPI site but you can pick some ideas for other frameworks, this example is SEO compatible for any web crawler.
The hard problem is to generate any (or selected) "AJAX page state" as plain HTML for SEO, in ItsNat is very easy and automatic, the same site is in the same time SPI or page based for SEO (or when JavaScript is disabled for accessibility). With other web frameworks you can ever follow the double site approach, one site is SPI based and another page based for SEO, for instance Twitter uses this "double site" technique.
Another thing that people may find useful...make sure to leave off ".py" from your module name. For example, if you are trying to generate documentation for 'original' in 'original.py':
yourcode_dir$ pydoc -w original.py no Python documentation found for 'original.py' yourcode_dir$ pydoc -w original wrote original.html
You simply need to make cab
a string:
cab = '6176'
As the error message states, you cannot do <int> in <string>
:
>>> 1 in '123'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not int
>>>
because integers and strings are two totally different things and Python does not embrace implicit type conversion ("Explicit is better than implicit.").
In fact, Python only allows you to use the in
operator with a right operand of type string if the left operand is also of type string:
>>> '1' in '123' # Works!
True
>>>
>>> [] in '123'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not list
>>>
>>> 1.0 in '123'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not float
>>>
>>> {} in '123'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not dict
>>>
I also found useful to run this:
./gradlew dI --dependency <your library>
This shows how are being dependencies resolved (dependencyInsight

Use RETURN QUERY
:
CREATE OR REPLACE FUNCTION word_frequency(_max_tokens int)
RETURNS TABLE (txt text -- also visible as OUT parameter inside function
, cnt bigint
, ratio bigint) AS
$func$
BEGIN
RETURN QUERY
SELECT t.txt
, count(*) AS cnt -- column alias only visible inside
, (count(*) * 100) / _max_tokens -- I added brackets
FROM (
SELECT t.txt
FROM token t
WHERE t.chartype = 'ALPHABETIC'
LIMIT _max_tokens
) t
GROUP BY t.txt
ORDER BY cnt DESC; -- potential ambiguity
END
$func$ LANGUAGE plpgsql;
Call:
SELECT * FROM word_frequency(123);
Explanation:
It is much more practical to explicitly define the return type than simply declaring it as record. This way you don't have to provide a column definition list with every function call. RETURNS TABLE
is one way to do that. There are others. Data types of OUT
parameters have to match exactly what is returned by the query.
Choose names for OUT
parameters carefully. They are visible in the function body almost anywhere. Table-qualify columns of the same name to avoid conflicts or unexpected results. I did that for all columns in my example.
But note the potential naming conflict between the OUT
parameter cnt
and the column alias of the same name. In this particular case (RETURN QUERY SELECT ...
) Postgres uses the column alias over the OUT
parameter either way. This can be ambiguous in other contexts, though. There are various ways to avoid any confusion:
ORDER BY 2 DESC
. Example:
ORDER BY count(*)
.plpgsql.variable_conflict
or use the special command #variable_conflict error | use_variable | use_column
in the function. See:
Don't use "text" or "count" as column names. Both are legal to use in Postgres, but "count" is a reserved word in standard SQL and a basic function name and "text" is a basic data type. Can lead to confusing errors. I use txt
and cnt
in my examples.
Added a missing ;
and corrected a syntax error in the header. (_max_tokens int)
, not (int maxTokens)
- type after name.
While working with integer division, it's better to multiply first and divide later, to minimize the rounding error. Even better: work with numeric
(or a floating point type). See below.
This is what I think your query should actually look like (calculating a relative share per token):
CREATE OR REPLACE FUNCTION word_frequency(_max_tokens int)
RETURNS TABLE (txt text
, abs_cnt bigint
, relative_share numeric) AS

The expression sum(t.cnt) OVER ()
is a window function. You could use a CTE instead of the subquery - pretty, but a subquery is typically cheaper in simple cases like this one.
A final explicit RETURN
statement is not required (but allowed) when working with OUT
parameters or RETURNS TABLE
(which makes implicit use of OUT
parameters).
round()
with two parameters only works for numeric
types. count()
in the subquery produces a bigint
result and a sum()
over this bigint
produces a numeric
result, thus we deal with a numeric
number automatically and everything just falls into place.
Here's another way:
fist_segment = "hello,"
second_segment = "world."
complete_string = "#{first_segment} #{second_segment}"
This should work:
$week_start = strtotime('last Sunday', time());
$week_end = strtotime('next Sunday', time());
$month_start = strtotime('first day of this month', time());
$month_end = strtotime('last day of this month', time());
$year_start = strtotime('first day of January', time());
$year_end = strtotime('last day of December', time());
echo date('D, M jS Y', $week_start).'<br/>';
echo date('D, M jS Y', $week_end).'<br/>';
echo date('D, M jS Y', $month_start).'<br/>';
echo date('D, M jS Y', $month_end).'<br/>';
echo date('D, M jS Y', $year_start).'<br/>';
echo date('D, M jS Y', $year_end).'<br/>';
What about this simple approach. Its working fine for me.
extension UITextField {
func charactersLimit(to:Int) {
if (self.text!.count > to) {
self.deleteBackward()
}
}
}
Then:
someTextField.charactersLimit(to:16)
Steves answer is correct though outdated with fragments. Here is an example with FragmentDialog.
The class:
public class SomeDialog extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
return new AlertDialog.Builder(getActivity())
.setTitle("Title")
.setMessage("Sure you wanna do this!")
.setNegativeButton(android.R.string.no, new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// do nothing (will close dialog)
}
})
.setPositiveButton(android.R.string.yes, new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// do something
}
})
.create();
}
}
To start dialog:
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
// Create and show the dialog.
SomeDialog newFragment = new SomeDialog ();
newFragment.show(ft, "dialog");
You could also let the class implement onClickListener
and use that instead of embedded listeners.
'some+multi+word+string'.replace(/\+/g, ' ');

$('#maindivid').find('input .inputclass').length
If you are in the middle of piping the result through map/filter/sort etc and you want to concat array of arrays, you can use reduce
let sorted_nums = ['1,3', '4,2']
.map(item => item.split(',')) // [['1', '3'], ['4', '2']]
.reduce((a, b) => a.concat(b)) // ['1', '3', '4', '2']
.sort() // ['1', '2', '3', '4']
To fit to the visible markers only, I've this method.
fitMapBounds() {
// Get all visible Markers
const visibleMarkers = [];
this.map.eachLayer(function (layer) {
if (layer instanceof L.Marker) {
visibleMarkers.push(layer);
}
});
// Ensure there's at least one visible Marker
if (visibleMarkers.length > 0) {
// Create bounds from first Marker then extend it with the rest
const markersBounds = L.latLngBounds([visibleMarkers[0].getLatLng()]);
visibleMarkers.forEach((marker) => {
markersBounds.extend(marker.getLatLng());
});
// Fit the map with the visible markers bounds
this.map.flyToBounds(markersBounds, {
padding: L.point(36, 36), animate: true,
});
}
}
I don't want to have to enable a reference library as I need my scripts to be portable. The Dim foo As New VBScript_RegExp_55.RegExp
line caused User Defined Type Not Defined
errors, but I found a solution that worked for me.
Update RE comments w/ @chrisneilsen :
I was under the impression that enabling a reference library was tied to the local computers settings, but it is in fact, tied directly to the workbook. So, you can enable a reference library, share a macro enabled workbook and the end user wouldn't have to enable the library as well. Caveat: The advantage to Late Binding is that the developer does not have to worry about the wrong version of an object library being installed on the user's computer. This likely would not be an issue w/ the VBScript_RegExp_55.RegExp
library, but I'm not sold that the "performance" benifit is worth it for me at this time, as we are talking imperceptible milliseconds in my code. I felt this deserved an update to help others understand. If you enable the reference library, you can use "early bind", but if you don't, as far as I can tell, the code will work fine, but you need to "late bind" and loose on some performance/debugging features.

What you'll want to do is put an example string in cell A1

In my case, the error occurred because I had not initialized the select list in the controller like this:
viewModel.MySelectList = new List<System.Web.Mvc.SelectListItem>();
As none of the existing answers made this clear to me, I post this. Perhaps it helps anybody.
some thing as follows ::
Add this After the body tag
This is a rough sketch, you will need to modify it according to your needs.
<script>
var f = document.createElement("form");
f.setAttribute('method',"post");
f.setAttribute('action',"submit.php");
var i = document.createElement("input"); //input element, text
i.setAttribute('type',"text");
i.setAttribute('name',"username");
var s = document.createElement("input"); //input element, Submit button
s.setAttribute('type',"submit");
s.setAttribute('value',"Submit");
f.appendChild(i);
f.appendChild(s);
//and some more input elements here
//and dont forget to add a submit button
document.getElementsByTagName('body')[0].appendChild(f);
</script>
There's a WebKit-Sharp component on Mono's Subversion Server. I can't find any web-viewable documentation on it, and I'm not even sure if it's WinForms or GTK# (can't grab the source from here to check at the moment), but it's probably your best bet, either way.
I think this component is CLI wrapper around webkit for Ubuntu. So this wrapper most likely could be not working on win32
Try check another variant - project awesomium - wrapper around google project "Chromium" that use webkit. Also awesomium has features like to should interavtive web pages on 3D objects under WPF
With Dulwich tip you should be able to do:
from dulwich.repo import Repo
Repo("/path/to/source").clone("/path/to/target")
This is still very basic - it copies across the objects and the refs, but it doesn't yet create the contents of the working tree if you create a non-bare repository.
I had two significant errors in my program. From the other answers, I learned in a single java program, one can not declare two classes as "public". So I changed the access specifier, but got another error as added to my question as "EDIT" that "Selection does not contain a main type". Finally I observed I forgot to add "String args[]" part in my main method. That's why the code was not working. After rectification, it worked as expected.
while
loops check the condition before the loop, do...while
loops check the condition after the loop. This is useful is you want to base the condition on side effects from the loop running or, like other posters said, if you want the loop to run at least once.
I understand where you're coming from, but the do-while
is something that most use rarely, and I've never used myself. You're not doing it wrong.
You're not doing it wrong. That's like saying someone is doing it wrong because they've never used the byte
primitive. It's just not that commonly used.
I've made an example for you showing how this could be done.
Notice the js but also that I changed #value into an input element
<input id="value" type="hidden" style="width:300px"/>
and that I am triggering the change
event for getting the initial values
$('#attribute').select2().on('change', function() {
$('#value').select2({data:data[$(this).val()]});
}).trigger('change');
Edit:
In the current version of select2 the class attribute is being transferred from the hidden input into the root element created by select2, even the select2-offscreen
class which positions the element way outside the page limits.
To fix this problem all that's needed is to add removeClass('select2-offscreen')
before applying select2 a second time on the same element.
$('#attribute').select2().on('change', function() {
$('#value').removeClass('select2-offscreen').select2({data:data[$(this).val()]});
}).trigger('change');
I've added a new Code Example to address this issue.
I'm not sure whether ZohoGorganzola's solution is correct; however, you may want to try getting at the element directly rather than trying to invoke a method on the jQuery collection, so instead of
$("#videoContainer").pause();
try
$("#videoContainer")[0].pause();
ActionResult is an abstract class.
ViewResult derives from ActionResult. Other derived classes include JsonResult and PartialViewResult.
You declare it this way so you can take advantage of polymorphism and return different types in the same method.
e.g:
public ActionResult Foo()
{
if (someCondition)
return View(); // returns ViewResult
else
return Json(); // returns JsonResult
}
Back in the day DIM reserved memory for the array and when memory was limited you had to be careful how you used it. I once wrote (in 1981) a BASIC program on TRS-80 Model III with 48Kb RAM. It wouldn't run on a similar machine with 16Kb RAM until I decreased the array size by changing the DIM statement
I actually had the same problem with a completely new repository. I had even tried creating one with git checkout -b master
, but it would not create the branch. I then realized if I made some changes and committed them, git created my master branch.
Related to Eugen's answer, you can solve this particular case by creating a wrapper POJO object that contains a Collection<COrder>
as its member variable. This will properly guide Jackson to place the actual Collection
data inside the POJO's member variable and produce the JSON you are looking for in the API request.
Example:
public class ApiRequest {
@JsonProperty("collection")
private Collection<COrder> collection;
// getters
}
Then set the parameter type of COrderRestService.postOrder()
to be your new ApiRequest
wrapper POJO instead of Collection<COrder>
.
I was able to achieve that by wrapping Button
with ConstraintLayout
:
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="wrap_content"
app:elevation="0dp">
<androidx.appcompat.widget.Toolbar

</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.appcompat.widget.Toolbar>
</com.google.android.material.appbar.AppBarLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
You may create a drawable resourcebutton_publish_rounded
, define the button properties and assign this file to button's android:background
property:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@color/green" />
<corners android:radius="100dp" />

About the version of Android SDK Build-tools, the answer is
By default, the Android SDK uses the most recent downloaded version of the Build Tools.
In Eclipse, you can choose a specific version by using the sdk.buildtools
property in the project.properties
file.
There seems to be no official page explaining all the build tools. Here is what the Android team says about this.
The [build] tools, such as aidl, aapt, dexdump, and dx, are typically called by the Android build tools or Android Development Tools (ADT), so you rarely need to invoke these tools directly. As a general rule, you should rely on the build tools or the ADT plugin to call them as needed.
Anyway, here is a synthesis of the differences between tools, platform-tools and build-tools:
$ANDROID_HOME/tools
ddms
(for debugging)$ANDROID_HOME/platform-tools
adb
(to manage the state of an emulator or an Android device)$ANDROID_HOME/build-tools/$VERSION/
aapt
(to generate R.java and unaligned, unsigned APKs), dx
(to convert Java bytecode to Dalvik bytecode), and zipalign
(to optimize your APKs)use the command prompt, as suggested. I figured out why explorer is so slow a while ago, it gives you an estimate of how long it will take to delete the files/folders. To do this, it has to scan the number of items and the size. This takes ages, hence the ridiculous wait with large folders.
Also, explorer will stop if there is a particular problem with a file,
A @Component requires a view whereas a @Directive does not.
I liken a @Directive to an Angular 1.0 directive with the option (Directives aren't limited to attribute usage.) Directives add behaviour to an existing DOM element or an existing component instance. One example use case for a directive would be to log a click on an element.restrict: 'A'
import {Directive} from '@angular/core';
@Directive({
selector: "[logOnClick]",
hostListeners: {
'click': 'onClick()',
},
})
class LogOnClick {
constructor() {}
onClick() { console.log('Element clicked!'); }
}
Which would be used like so:
<button logOnClick>I log when clicked!</button>
A component, rather than adding/modifying behaviour, actually creates its own view (hierarchy of DOM elements) with attached behaviour. An example use case for this might be a contact card component:
import {Component, View} from '@angular/core';
@Component({
selector: 'contact-card',
template: `
<div>
<h1>{{name}}</h1>
<p>{{city}}</p>
</div>
`
})
class ContactCard {
@Input() name: string
@Input() city: string
constructor() {}
}
Which would be used like so:
<contact-card [name]="'foo'" [city]="'bar'"></contact-card>
ContactCard
is a reusable UI component that we could use anywhere in our application, even within other components. These basically make up the UI building blocks of our applications.
Write a component when you want to create a reusable set of DOM elements of UI with custom behaviour. Write a directive when you want to write reusable behaviour to supplement existing DOM elements.
Sources:
The URL is relative to the location of the CSS file, so this should work for you:
url('../../images/image.jpg')
The relative URL goes two folders back, and then to the images
folder - it should work for both cases, as long as the structure is the same.
From https://www.w3.org/TR/CSS1/#url:
Partial URLs are interpreted relative to the source of the style sheet, not relative to the document
For Web API 2, you can implement IHttpActionResult
. Here's mine:
using System;
using System.IO;
using System.Net;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading;
using System.Threading.Tasks;
using System.Web;
using System.Web.Http;
class FileResult : IHttpActionResult
{
private readonly string _filePath;
private readonly string _contentType;
public FileResult(string filePath, string contentType = null)
{
if (filePath == null) throw new ArgumentNullException("filePath");
_filePath = filePath;
_contentType = contentType;
}
public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
{
var response = new HttpResponseMessage(HttpStatusCode.OK)
{
Content = new StreamContent(File.OpenRead(_filePath))
};
var contentType = _contentType ?? MimeMapping.GetMimeMapping(Path.GetExtension(_filePath));
response.Content.Headers.ContentType = new MediaTypeHeaderValue(contentType);
return Task.FromResult(response);
}
}
Then something like this in your controller:
[Route("Images/{*imagePath}")]
public IHttpActionResult GetImage(string imagePath)
{
var serverPath = Path.Combine(_rootPath, imagePath);
var fileInfo = new FileInfo(serverPath);
return !fileInfo.Exists
? (IHttpActionResult) NotFound()
: new FileResult(fileInfo.FullName);
}
And here's one way you can tell IIS to ignore requests with an extension so that the request will make it to the controller:
<!-- web.config -->
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
Also, you can use bool method(s)
Query :
DataTable tempData = (DataTable)grdUsageRecords.DataSource;
var query = from r in tempData.AsEnumerable()
where isValid(Field<string>("UserName"))// && otherMethod() && otherMethod2()
select r;
DataTable newDT = query.CopyToDataTable();
Method:
bool isValid(string userName)
{
if(userName == "XXXX" || userName == "YYYY")
return false;
else return true;
}
For Windows users, you can add a system environment variable named _JAVA_OPTIONS, and set the heap size values there. The JVM should be able to grab the virtual machine options from _JAVA_OPTIONS.
The problem is that .NET will always round a double
to 15 significant decimal digits before applying your formatting, regardless of the precision requested by your format and regardless of the exact decimal value of the binary number.
I'd guess that the Visual Studio debugger has its own format/display routines that directly access the internal binary number, hence the discrepancies between your C# code, your C code and the debugger.
There's nothing built-in that will allow you to access the exact decimal value of a double
, or to enable you to format a double
to a specific number of decimal places, but you could do this yourself by picking apart the internal binary number and rebuilding it as a string representation of the decimal value.
Alternatively, you could use Jon Skeet's DoubleConverter
class (linked to from his "Binary floating point and .NET" article). This has a ToExactString
method which returns the exact decimal value of a double
. You could easily modify this to enable rounding of the output to a specific precision.
double i = 10 * 0.69;
Console.WriteLine(DoubleConverter.ToExactString(i));
Console.WriteLine(DoubleConverter.ToExactString(6.9 - i));
Console.WriteLine(DoubleConverter.ToExactString(6.9));
// 6.89999999999999946709294817992486059665679931640625
// 0.00000000000000088817841970012523233890533447265625
// 6.9000000000000003552713678800500929355621337890625
make sure your user has attributes on its role. for example:
postgres=# \du
List of roles
Role name | Attributes | Member of
-----------+------------------------------------------------+-----------
flux | | {}
postgres | Superuser, Create role, Create DB, Replication | {}
after performing the following command:
postgres=# ALTER ROLE flux WITH Superuser;
ALTER ROLE
postgres=# \du
List of roles
Role name | Attributes | Member of
-----------+------------------------------------------------+-----------
flux | Superuser | {}
postgres | Superuser, Create role, Create DB, Replication | {}
it fixed the problem.
see tutorial for roles and stuff here: https://www.digitalocean.com/community/tutorials/how-to-use-roles-and-manage-grant-permissions-in-postgresql-on-a-vps--2
In MAMP, You could load huge files by :
creating a new folder in this directory /MAMP/bin/phpMyAdmin/"folderName"
and then edit "/MAMP/bin/phpMyAdmin/config.inc.php" line 531 :
$cfg['UploadDir']= 'folderName';
Copy your .sql or .csv Files into this folder.
Now you will have another option in "PhpMyAdmin" : Select from the web server upload directory newFolder/: You could select your file and import it.
You could load any file now !!
You should add the target="_blank"
and rel="noopener noreferrer"
in the anchor tag.
For example:
<a target="_blank" rel="noopener noreferrer" href="http://your_url_here.html">Link</a>
Adding rel="noopener noreferrer"
is not mandatory, but it's a recommended security measure. More information can be found in the links below.

Do a SELECT COUNT(*) FROM ...
query instead.
Storing a list of object instances is very simple
class MyClass(object):
def __init__(self, number):
self.number = number
my_objects = []
for i in range(100):
my_objects.append(MyClass(i))
# later
for obj in my_objects:
print obj.number
If you don't know the index beforehand here is a function that will work
def reverse_index(l, index):
try:
l.pop(index)
return l
except IndexError:
return False
There is also a slightly simpler way of removing the value.
mydropdownid.Items.Remove("Chicago");
<dropdown id=mydropdown .....>
values
You'll have it in your connection string like:
"mysql:host=$host;dbname=$db;charset=utf8"
HOWEVER, prior to PHP 5.3.6, the charset option was ignored. If you're running an older version of PHP, you must do it like this:
$dbh = new PDO("mysql:$connstr", $user, $password);
$dbh->exec("set names utf8");
dataGridView1.Rows[i].Cells[7].Style.BackColor = Color.LightGreen;
You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:
import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values
... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.
In RHEL 7, I use this command to filter several ports in LISTEN State:

Use NetworkMonitor to monitoring network state and internet connection.
Sample:
namespace AmRoNetworkMonitor.Demo
{
using System;
internal class Program

NetworkMonitor.StateChanged += NetworkMonitor_StateChanged;
NetworkMonitor.StartMonitor();
Console.WriteLine("Press any key to stop monitoring.");
Console.ReadKey();
NetworkMonitor.StopMonitor();
Console.WriteLine("Press any key to close program.");
Console.ReadKey();
}
private static void NetworkMonitor_StateChanged(object sender, StateChangeEventArgs e)
{
Console.WriteLine(e.IsAvailable ? "Is Available" : "Is Not Available");
}
}
}
seems like opening a new session is the key.
see this answer.
and here is an awesome explanation about this error
Here are all of the previous answers summarized:
The code should look like this:
import sys
def hello(a, b):
print "hello and that's your sum:"
sum = a+b
print sum
if __name__== "__main__":
hello(int(sys.argv[1]), int(sys.argv[2]))
Then run the code with this command:
python hello.py 1 1
Because on Unix, usually, the current directory is not in $PATH
.
When you type a command the shell looks up a list of directories, as specified by the PATH
variable. The current directory is not in that list.
The reason for not having the current directory on that list is security.
Let's say you're root and go into another user's directory and type sl
instead of ls
. If the current directory is in PATH
, the shell will try to execute the sl
program in that directory (since there is no other sl
program). That sl
program might be malicious.
It works with ./
because POSIX specifies that a command name that contain a /
will be used as a filename directly, suppressing a search in $PATH
. You could have used full path for the exact same effect, but ./
is shorter and easier to write.
EDIT
That sl
part was just an example. The directories in PATH
are searched sequentially and when a match is made that program is executed. So, depending on how PATH
looks, typing a normal command may or may not be enough to run the program in the current directory.
It depends on the platform and compiler that you're using. Some compilers store directly in the code segment. Static variables are always only accessible to the current translation unit and the names are not exported thus the reason name collisions never occur.
You need to identify the columns based on their position in dataframe. For example, if you want to drop (del) column number 2,3 and 5, it will be,
df.drop(df.columns[[2,3,5]], axis = 1)
You can use from bellow code for date and time :
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
//get current date time with Calendar()
Calendar cal = Calendar.getInstance();
System.out.println("Current Date Time : " + dateFormat.format(cal.getTime()));
cal.add(Calendar.DATE, 1);
System.out.println("Add one day to current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.MONTH, 1);
System.out.println("Add one month to current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.YEAR, 1);
System.out.println("Add one year to current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.HOUR, 1);
System.out.println("Add one hour to current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.MINUTE, 1);
System.out.println("Add one minute to current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.SECOND, 1);
System.out.println("Add one second to current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.DATE, -1);
System.out.println("Subtract one day from current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.MONTH, -1);
System.out.println("Subtract one month from current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.YEAR, -1);
System.out.println("Subtract one year from current date : " + dateFormat.format(cal.getTime()));
cal = Calendar.getInstance();
cal.add(Calendar.HOUR, -1);
System.out.println("Subtract one hour from current date : " + dateFormat.format(cal.getTime()));

{

You will want to set the MdiParent
property of your new form to the name of the MDI parent form, as follows:
dim form as new yourform
form.show()
form.MdiParent = nameParent
You can't change the type of an existing property.
You can add a property:
interface A {
newProperty: any;
}
But changing a type of existing one:
interface A {
property: any;
}
Results in an error:
Subsequent variable declarations must have the same type. Variable 'property' must be of type 'number', but here has type 'any'
You can of course have your own interface which extends an existing one. In that case, you can override a type only to a compatible type, for example:
interface A {
x: string | number;
}
interface B extends A {
x: number;
}
By the way, you probably should avoid using Object
as a type, instead use the type any
.
In the docs for the any
type it states:
The any type is a powerful way to work with existing JavaScript, allowing you to gradually opt-in and opt-out of type-checking during compilation. You might expect Object to play a similar role, as it does in other languages. But variables of type Object only allow you to assign any value to them - you can’t call arbitrary methods on them, even ones that actually exist:
let notSure: any = 4;
notSure.ifItExists(); // okay, ifItExists might exist at runtime
notSure.toFixed(); // okay, toFixed exists (but the compiler doesn't check)
let prettySure: Object = 4;
prettySure.toFixed(); // Error: Property 'toFixed' doesn't exist on type 'Object'.
You can return json in PHP this way:
header('Content-Type: application/json');
echo json_encode(array('foo' => 'bar'));
exit;
If you set the image in div, you also must set both height and width. This may cause the image to lose its proportion. In addition, you must set the image URL in CSS instead of HTML.
Instead, you can set the image using the IMG tag. In the container class you can only set the width in percent or pixel and the height will automatically maintain proportion.
This is also more effective for accessibility of search engines and reading engines to define an image using an IMG tag.
.container {_x000D_
margin: auto;_x000D_
width: 200px;_x000D_

Why are you using a macro? Excel has Password Protection built-in. When you select File/Save As... there should be a Tools button by the Save button, click it then "General Options" where you can enter a "Password to Open" and a "Password to Modify".
TryParse works if your number is less than Int32.MaxValue. This also gives you the opportunity to handle badly formatted strings. Works the same for Int64.MaxValue and Int64.TryParse.
int number;
if(Int32.TryParse(nvarchar, out number))
{
// etc...
number.ToString();
}
From the Jquery docs: you specify the async option to be false to get a synchronous Ajax request. Then your callback can set some data before your mother function proceeds.
Here's what your code would look like if changed as suggested:
beforecreate: function(node,targetNode,type,to) {
jQuery.ajax({
url: url,
success: function(result) {
if(result.isOk == false)
alert(result.message);
},
async: false
});
}
this is because $.ajax is the only request type that you can set the asynchronousity for
The approach I would take is: when reading the chapters from the database, instead of a collection of chapters, use a collection of books. This will have your chapters organised into books and you'll be able to use information from both classes to present the information to the user (you can even present it in a hierarchical way easily when using this approach).
For reset all field in one form you can use event.target.reset()
const app = new Vue({_x000D_

return{ _x000D_
name : null,_x000D_

event.preventDefault(),_x000D_
//process... _x000D_
event.target.reset()_x000D_

testCompile 'junit:junit:4.12'

testCompile group: 'org.hamcrest', name: 'hamcrest-library', version: '2.1'
First - most classes will never need to be thread-safe. Use YAGNI: only apply thread-safety when you know you actually are going to use it (and test it).
For the method-level stuff, there is [MethodImpl]
:
[MethodImpl(MethodImplOptions.Synchronized)]
public void SomeMethod() {/* code */}
This can also be used on accessors (properties and events):
private int i;
public int SomeProperty
{
[MethodImpl(MethodImplOptions.Synchronized)]
get { return i; }
[MethodImpl(MethodImplOptions.Synchronized)]
set { i = value; }
}
Note that field-like events are synchronized by default, while auto-implemented properties are not:
public int SomeProperty {get;set;} // not synchronized
public event EventHandler SomeEvent; // synchronized
Personally, I don't like the implementation of MethodImpl
as it locks this
or typeof(Foo)
- which is against best practice. The preferred option is to use your own locks:
private readonly object syncLock = new object();
public void SomeMethod() {
lock(syncLock) { /* code */ }
}
Note that for field-like events, the locking implementation is dependent on the compiler; in older Microsoft compilers it is a lock(this)
/ lock(Type)
- however, in more recent compilers it uses Interlocked
updates - so thread-safe without the nasty parts.
This allows more granular usage, and allows use of Monitor.Wait
/Monitor.Pulse
etc to communicate between threads.

None of these answers worked for me in all cases. I had to go directly to Google's Documentation https://developer.android.com/guide/topics/providers/document-provider.html on this topic and found this useful method:
private Bitmap getBitmapFromUri(Uri uri) throws IOException {
ParcelFileDescriptor parcelFileDescriptor =
getContentResolver().openFileDescriptor(uri, "r");
FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
Bitmap image = BitmapFactory.decodeFileDescriptor(fileDescriptor);
parcelFileDescriptor.close();
return image;
}
You can use this bitmap to display it in an Image View.
Maybe you can load on your title all the tabs titles in one string, and then once you load one of the tabs change the title via javascript
ex: at first set your title to
my app | description | contact | about us |
once you load one of the tabs run:
document.title = "my app | tab title";
System.String
(with capital S) is already nullable, you do not need to declare it as such.
(string? myStr)
is wrong.
char **orderIds;
orderIds = malloc(variableNumberOfElements * sizeof(char*));
for(int i = 0; i < variableNumberOfElements; i++) {
orderIds[i] = malloc((ID_LEN + 1) * sizeof(char));
strcpy(orderIds[i], your_string[i]);
}
Instead of using a <text>
tag, the <foreignObject>
tag can be used, which allows for XHTML content with CSS.
If you just need to try something out quickly, here's a quick and dirty solution. Use single quotes for the attribute value:
<parameter name='Quote = " '>
You want:
this.value = ''; // straight JS, no jQuery
or
$(this).val(''); // jQuery
With $(this).value = ''
you're assigning an empty string as the value
property of the jQuery object that wraps this
-- not the value
of this
itself.
I work on 60-70% zoom vue and my dropdown are unreadable so I made this simple code to overcome the issue
Note that I selected first all my dropdown lsts (CTRL+mouse click), went on formula tab, clicked "define name" and called them "ProduktSelection"
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim KeyCells As Range
Set KeyCells = Range("ProduktSelection")
If Not Application.Intersect(KeyCells, Range(Target.Address)) _
Is Nothing Then
ActiveWindow.Zoom = 100
End If
End Sub
I then have another sub
Private Sub Worksheet_Change(ByVal Target As Range)
where I come back to 65% when value is changed.
In your html :
<a href="javascript:void(0);" ng-click="go_back()">Go Back</a>
On your main controller :
$scope.go_back = function() {
$window.history.back();
};
When user click on Go Back link the controller function is called and it will go back to previous route.
Modules Preconditions:
The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (
precondition="managedHandler"
) only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />
If you remove the attribute
precondition="managedHandler"
, Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "
managedHandler
" precondition.To enable all managed modules to run for all requests without configuring each module entry to remove the "
managedHandler
" precondition, use therunAllManagedModulesForAllRequests
property in the<modules>
section:<modules runAllManagedModulesForAllRequests="true" />
When you use this property, the "
managedHandler
" precondition has no effect and all managed modules run for all requests.
Copied from IIS Modules Overview: Preconditions
Yes, that's the standard way to do specializiation explicit instantiation. As you stated, you cannot instantiate this template with other types.
Edit: corrected based on comment.
These snippets all perform exactly the same thing:
element.on('click', function () { ... });
element.bind('click', function () { ... });
element.click(function () { ... });
However, they are very different from these, which all perform the same thing:
element.on('click', 'selector', function () { ... });
element.delegate('click', 'selector', function () { ... });
$('selector').live('click', function () { ... });
The second set of event handlers use event delegation and will work for dynamically added elements. Event handlers that use delegation are also much more performant. The first set will not work for dynamically added elements, and are much worse for performance.
jQuery's on()
function does not introduce any new functionality that did not already exist, it is just an attempt to standardize event handling in jQuery (you no longer have to decide between live, bind, or delegate).
I was getting the same issue and found that OpenSSH service was not running and it was causing the issue. After starting the SSH service it worked.
To check if SSH service is running or not:
ssh localhost
To start the service, if OpenSSH is already installed:

From the git-diff
manpage:
git diff [--options] <commit> <commit> [--] [<path>...]
For instance, to see the difference for a file "main.c" between now and two commits back, here are three equivalent commands:
$ git diff HEAD^^ HEAD main.c
$ git diff HEAD^^..HEAD -- main.c
$ git diff HEAD~2 HEAD -- main.c
When doing a getObject()
from the S3 API, per the docs the contents of your file are located in the Body
property, which you can see from your sample output. You should have code that looks something like the following
const aws = require('aws-sdk');
const s3 = new aws.S3(); // Pass in opts to S3 if necessary
var getParams = {
Bucket: 'abc', // your bucket name,
Key: 'abc.txt' // path to the object you're looking for
}
s3.getObject(getParams, function(err, data) {
// Handle any error and exit
if (err)
return err;
// No error happened
// Convert Body from a Buffer to a String
let objectData = data.Body.toString('utf-8'); // Use the encoding necessary
});
You may not need to create a new buffer from the data.Body
object but if you need you can use the sample above to achieve that.
Is better to use parse_url
to retrieve only the path, and then getting only the filename with the basename
. This way we also avoid query parameters.
<?php
// url to inspect
$url = 'http://www.example.com/image.jpg?q=6574&t=987';
// parsed path
$path = parse_url($url, PHP_URL_PATH);
// extracted basename
echo basename($path);
?>
Is somewhat similar to Sultan answer excepting that I'm using component
parse_url
parameter, to obtain only the path.
You can use .scrollIntoView()
for this. It will bring a specific element into the viewport.
Example:
document.getElementById( 'bottom' ).scrollIntoView();
Demo: http://jsfiddle.net/ThinkingStiff/DG8yR/
Script:
function top() {
document.getElementById( 'top' ).scrollIntoView();
};
function bottom() {
document.getElementById( 'bottom' ).scrollIntoView();
window.setTimeout( function () { top(); }, 2000 );
};
bottom();
HTML:
<div id="top">top</div>
<div id="bottom">bottom</div>
CSS:
#top {
border: 1px solid black;
height: 3000px;
}
#bottom {
border: 1px solid red;
}
Asus Nexus 7 on my Windows 7 64 bits computer for development purposes :
I tried to install the driver for the nexus 7 manually like explained in the official tutorial of Asus
Unfortunately, I had an error, Windows couldn't recognize the driver.
I tried to change the USB connection mode to PTP or MTP by going in the storage menu and clicking on the top right menu . In both cases, windows recognize the devices but it still didn't work in debugging mode.
The only way it worked for me is by installing : adb universal installer . I scanned it before clicking on the executable, it seems to be fine.
An important thing to consider is that some users and some resellers (Dell) install a 64 bit VM on their 64 bit Windows, and you can't use the same SWT library on 32 bit and 64 bit VMs.
This means you will need to distribute and test different packages depending on whether users have 32-bit or a 64-bit Java VM. See this problem with Azureus, for instance, but you also have it with Eclipse, where as of today the builds on the front download page do not run on a 64 bit VM.
How about this
UPDATE table SET columnB = columnA;
This will update every row.
You have to tell your SQLCommand objects to use the transaction:
cmd1.Transaction = transaction;
or in the constructor:
SqlCommand cmd1 = new SqlCommand("select...", connectionsql, transaction);
Make sure to have the connectionsql object open, too.
But all you are doing are SELECT statements. Transactions would benefit more when you use INSERT, UPDATE, etc type actions.
Add the following CSS class to your stylesheet:
.my-spacer {
flex: 1 1 auto;
}
Place an empty element between the element on the left and the element you wish to right-align:
<span class="my-spacer"></span>
You would have to first create your migration for the model basics then you create another migration to modify your previous using the change_column ...
def change
change_column :widgets, :colour, :string, default: 'red'
end
I like this solution:
String delim = " - ", string = "";
for (String item : myCollection)
string += delim + item;
string = string.substring(delim.length());
I assume it can make use of StringBuilder too.
You can find a nice list of corresponding URL encoded characters on W3Schools.
+
becomes %2B
%20
You've got the same basic restriction when running a 32bit process under Win64. Your app runs in a 32 but subsystem which does its best to look like Win32, and this will include the memory restrictions for your process (lower 2GB for you, upper 2GB for the OS)
Hey, this might not be the most ideal solution, but it works for me. I ended up creating a Python-Markdown LaTeX extension.
https://github.com/justinvh/Markdown-LaTeX
It adds support for inline math and text expressions using a $math$ and %text% syntax. The extension is a preprocessor that will use latex/dvipng to generate pngs for the respective equations/text and then base64 encode the data to inline the images directly, rather than have external images.
The data is then put in a simple-delimited cache file that encodes the expression to the base64 representation. This limits the number of times latex actually has to be run.
Here is an example:
%Hello, world!% This is regular text, but this: $y = mx + b$ is not.
The output:
$ markdown -x latex test.markdown
<p><img class='latex-inline math-false' alt='Hello, world!' id='Helloworld' src='data:image/png;base64,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'> This is regular text, but this: <img class='latex-inline math-true' alt='y = mx + b' id='ymxb' src='data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAFIAAAAOBAMAAABOTlYkAAAAMFBMVEX///9ERETu7u4yMjK6urp2dnZUVFSIiIjMzMwQEBDc3NwiIiJmZmaYmJiqqqoAAADS00rKAAAAAXRSTlMAQObYZgAAAOtJREFUKM9jYCAACsCk4wYGgiABTLInEKuS+QGxKvkVGBj47jBwI8tcffI84e45BoZ7GVcLECo9751iWLeSoRPITBQEggMMDBy9sxj2MDgz8DIE8yCpPMxwjWFBGUMMkpFcbAEMvxjKGLgYxIE8NkHBiYIyQMY+hmoGhi0Mdsi2czawbGCQBTJ+ILvzE0MaA9MHIIWwnWE9A+sBpk8LGDgmMCnAVXJNYPgCJHhRQvUiA/cDXoECZx4DXoSZTBtYgaaEPw5AVnkOGBRc5xTcbsReQrL9+nWwyxbgC88DcJZ+QygDcYD1+QPiFAIAtLA8KPZOGFEAAAAASUVORK5CYII='> is not.</p>

One can also checkout all files from the other branch into master:
git checkout master
git checkout better_branch -- .
and then commit all changes.
Usually you restore your state in onCreate()
. It is possible to restore it in onRestoreInstanceState()
as well, but not very common. (onRestoreInstanceState()
is called after onStart()
, whereas onCreate()
is called before onStart()
.
Use the put methods to store values in onSaveInstanceState()
:
protected void onSaveInstanceState(Bundle icicle) {
super.onSaveInstanceState(icicle);
icicle.putLong("param", value);
}
And restore the values in onCreate()
:
public void onCreate(Bundle icicle) {
if (icicle != null){
value = icicle.getLong("param");
}
}
$("#expires1").click(function(){
if (this.checked)
alert("testing....");
});
Kdialog and dialog are both good, but I'd recommend Zenity. Quick, easy, and much better looking the xmessage or dialog.

detect line breaks in a text area input
You can try this:
var submit = document.getElementById('submit');_x000D_
_x000D_
submit.addEventListener('click', function(){_x000D_
var textContent = document.querySelector('textarea').value;_x000D_

<textarea cols=30 rows=10 >This is some text_x000D_
this is another text_x000D_
_x000D_
Another text again and again</textarea>_x000D_
<input type='submit' id='submit'>_x000D_
_x000D_
_x000D_
<p id='output'></p>
_x000D_
document.querySelector('textarea').value;
will get the text content of the
textarea and textContent.replace(/\n/g, '<br/>')
will find all the newline character in the source code /\n/g
in the content and replace it with the html line-break <br/>

OS X uses a mix of BSD and GNU tools, so best always check the documentation (although I had it that less
didn't even conform to the OS X manpage):
sed takes the argument after -i
as the extension for backups. Provide an empty string (-i ''
) for no backups.
The following should do:
LC_ALL=C find . -type f -name '*.txt' -exec sed -i '' s/this/that/ {} +
The -type f
is just good practice; sed will complain if you give it a directory or so.
-exec
is preferred over xargs
; you needn't bother with -print0
or anything.
The {} +
at the end means that find
will append all results as arguments to one instance of the called command, instead of re-running it for each result. (One exception is when the maximal number of command-line arguments allowed by the OS is breached; in that case find
will run more than one instance.)
I had this or a similar problem after installing Tomcat.
The other answers didn't quite work, but got me on the right path. I answered this at https://stackoverflow.com/a/20762179/3128838 after discovering a YouTube video showing the exact problem I was having.
You are just using a single parameter inside the function hence it is working fine in both the cases like follows:
MsgBox "Hello world!"
MsgBox ("Hello world!")
But when you'll use more than one parameter, In VBScript method will parenthesis will throw an error and without parenthesis will work fine like:
MsgBox "Hello world!", vbExclamation
The above code will run smoothly but
MsgBox ("Hello world!", vbExclamation)
will throw an error. Try this!! :-)
I hit this problem while working on a server with AFS disk space because my authentication token had expired, which yielded Permission Denied
responses when the redis-server tried to save. I solved this by refreshing my token:
kinit USERNAME_HERE -l 30d && aklog
There might be a fix to <input type="button">
- but if there is, I don't know it.
Otherwise, a good option seems to be to replace it with a carefully styled a
element.
Example: http://jsfiddle.net/Uka5v/
.button {
background-color: #E3E1B8;
padding: 2px 4px;
font: 13px sans-serif;
text-decoration: none;
border: 1px solid #000;
border-color: #aaa #444 #444 #aaa;
color: #000
}
Upsides include that the a
element will style consistently between different (older) versions of Internet Explorer without any extra work, and I think my link looks nicer than that button :)
MySQL will assume the part before the equals references the columns named in the INSERT INTO clause, and the second part references the SELECT columns.
INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct,
inact, inadur, inadist,
smlct, smldur, smldist,
larct, lardur, lardist,
emptyct, emptydur)
SELECT id, uid, t.location, t.animal, t.starttime, t.endtime, t.entct,
t.inact, t.inadur, t.inadist,
t.smlct, t.smldur, t.smldist,
t.larct, t.lardur, t.lardist,
t.emptyct, t.emptydur
FROM tmp t WHERE uid=x
ON DUPLICATE KEY UPDATE entct=t.entct, inact=t.inact, ...
I know that I'm a few years late, but I came across this issue and took an unorthodox approach. I wanted to do it without making a new class, so this is what I came up with:
int x = 0;
new Thread((new Runnable() {
int x;
public void run() {
// stuff with x and whatever else you want
}
public Runnable pass(int x) {
this.x = x;
return this;
}
}).pass(x)).start();
fix for hub
cli tool:
git config --global hub.protocol https
for long termgit remote add OOPS https://github.com/isomorphisms/go.git
&& git push OOPS
for immediate fixThis error occurs with the hub
command line tool because of their wrong default hub.protocol
git-config value. They set repos to
git://github.com/schacon/ticgit.git
instead of what github actually accepts, namely https://github.com/schacon/ticgit.git
.
Reading LESS=+/"HTTPS instead" man hub
will explain where the above "long-term fix" command comes from.
Use max-width:100%;
, height: auto;
and display:block;
as follow:
image {
max-width:100%;
height: auto;
display:block;
}
Put a script somewhere in your document root
<?php
phpinfo();
Among others the output of the function will tell you which php.ini
s are parsed before the script got executed.
import csv
inf = csv.reader(open('yourfile.csv','r'))
for row in inf:
print row[1]
These all are ways:
String imageUri = "drawable://" + R.drawable.image;
Other ways I tested
Uri path = Uri.parse("android.resource://com.segf4ult.test/" + R.drawable.icon);
Uri otherPath = Uri.parse("android.resource://com.segf4ult.test/drawable/icon");
String path = path.toString();
String path = otherPath .toString();
You need a root node
<?xml version="1.0" encoding="ISO-8859-1"?>

There could be many reason why document.getElementById
doesn't work
You have an invalid ID
ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods ("."). (resource: What are valid values for the id attribute in HTML?)
you used some id that you already used as <meta>
name in your header (e.g. copyright, author... ) it looks weird but happened to me: if your 're using IE take a look at
(resource: http://www.phpied.com/getelementbyid-description-in-ie/)
you're targeting an element inside a frame or iframe. In this case if the iframe loads a page within the same domain of the parent you should target the contentdocument
before looking for the element
(resource: Calling a specific id inside a frame)
you're simply looking to an element when the node is not effectively loaded in the DOM, or maybe it's a simple misspelling
I doubt you used same ID twice or more: in that case document.getElementById
should return at least the first element
For those that want to continue using version ^3.0.1 be aware of the changes to how you use the MongoClient.connect()
method. The callback doesn't return db
instead it returns client
, against which there is a function called db(dbname)
that you must invoke to get the db
instance you are looking for.
const MongoClient = require('mongodb').MongoClient;
const assert = require('assert');
// Connection URL
const url = 'mongodb://localhost:27017';
// Database Name
const dbName = 'myproject';
// Use connect method to connect to the server
MongoClient.connect(url, function(err, client) {
assert.equal(null, err);
console.log("Connected successfully to server");
const db = client.db(dbName);
client.close();
});
Set LDFLAGS and CFLAGS when you run make:
$ LDFLAGS="-L/home/me/local/lib" CFLAGS="-I/home/me/local/include" make
If you don't want to do that a gazillion times, export these in your .bashrc (or your shell equivalent). Also set LD_LIBRARY_PATH to include /home/me/local/lib:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/me/local/lib
I created a global define with more information:
#include <iostream>
#include <ctime>
#include <iomanip>
#define __FILENAME__ (__builtin_strrchr(__FILE__, '/') ? __builtin_strrchr(__FILE__, '/') + 1 : __FILE__) // only show filename and not it's path (less clutter)
#define INFO std::cout << std::put_time(std::localtime(&time_now), "%y-%m-%d %OH:%OM:%OS") << " [INFO] " << __FILENAME__ << "(" << __FUNCTION__ << ":" << __LINE__ << ") >> "
#define ERROR std::cout << std::put_time(std::localtime(&time_now), "%y-%m-%d %OH:%OM:%OS") << " [ERROR] " << __FILENAME__ << "(" << __FUNCTION__ << ":" << __LINE__ << ") >> "
static std::time_t time_now = std::time(nullptr);
Use it like this:
INFO << "Hello world" << std::endl;
ERROR << "Goodbye world" << std::endl;
Sample output:
16-06-23 21:33:19 [INFO] main.cpp(main:6) >> Hello world
16-06-23 21:33:19 [ERROR] main.cpp(main:7) >> Goodbye world
Put these lines in your header file. I find this very useful for debugging, etc.
You should write the pickled data with a lower protocol number in Python 3. Python 3 introduced a new protocol with the number 3
(and uses it as default), so switch back to a value of 2
which can be read by Python 2.
Check the protocol
parameter in pickle.dump
. Your resulting code will look like this.
pickle.dump(your_object, your_file, protocol=2)
There is no protocol
parameter in pickle.load
because pickle
can determine the protocol from the file.
Option1:
List<String> list = Arrays.asList("hello");
Option2:
List<String> list = new ArrayList<String>(Arrays.asList("hello"));
In my opinion, Option1 is better because
asList
method creates and returns an ArrayList Object.Please refer to the documentation here
If it supports standard regex...
find:
^.*#RedirectMatch Permanent.*$

Replace with nothing.
If, like me, you are still using the browser version (which will be deprecated soon), have you tried the "Code" button?
This should generate a snippet which contains the entire request Postman is firing. You can even choose the language for the snippet. I find it quite handy when I need to debug stuff.
Hope this helps.
The docs indicate that numpy.correlate
is not what you are looking for:
numpy.correlate(a, v, mode='valid', old_behavior=False)[source]
Cross-correlation of two 1-dimensional sequences.
This function computes the correlation as generally defined in signal processing texts:
z[k] = sum_n a[n] * conj(v[n+k])
with a and v sequences being zero-padded where necessary and conj being the conjugate.
Instead, as the other comments suggested, you are looking for a Pearson correlation coefficient. To do this with scipy try:
from scipy.stats.stats import pearsonr
a = [1,4,6]
b = [1,2,3]
print pearsonr(a,b)
This gives
(0.99339926779878274, 0.073186395040328034)
You can also use numpy.corrcoef
:
import numpy
print numpy.corrcoef(a,b)
This gives:
[[ 1. 0.99339927]
[ 0.99339927 1. ]]
This issue is not always related to the PowerShell Execution Policy. My machine is configured as "Unrestricted" for both PowerShell x64 and x86, but I still get this error message from times to times in Visual Studio 2013.
When I try to open the Package Manager Console:
Windows PowerShell updated your execution policy successfully, but the setting is overridden by a policy defined at a more specific scope. Due to the override, your shell will retain its current effective execution policy of Unrestricted. Type "Get-ExecutionPolicy -List" to view your execution policy settings. For more information please see "Get-Help Set-ExecutionPolicy".
This is not a valid error message.
Rebooting Visual Studio does not always resolve the problem.
Running the process as an admin never resolves the problem.
Like Declan, the latest update of the Package Manager plugin fixed the issue: 2.8.60723.765
0755
= User:rwx
Group:r-x
World:r-x
0750

(i.e. World: no access)
r = read
w = write
x = execute (traverse for directories)
Instead of using the new pragmas, you can also use __attribute__((optimize("O0")))
for your needs. This has the advantage of just applying to a single function and not all functions defined in the same file.
Usage example:
void __attribute__((optimize("O0"))) foo(unsigned char data) {
// unmodifiable compiler code
}
If you are looking for Uniformly distributed pseudorandom integers use:
randi([13, 20])
This error is caused by:
Y = Dataset.iloc[:,18].values
Indexing is out of bounds here most probably because there are less than 19 columns in your Dataset, so column 18 does not exist. The following code you provided doesn't use Y at all, so you can just comment out this line for now.
From what the error message complains about, it sounds like you should rather try to fix the source code. The compiler complains about difference in declaration, similar to for instance
void foo(int i);
...
void foo(double d) {
...
}
and this is not valid C code, hence the compiler complains.
Maybe your problem is that there is no prototype available when the function is used the first time and the compiler implicitly creates one that will not be static. If so the solution is to add a prototype somewhere before it is first used.
You can make a directory "fonts" in a root of your project and put your fonts (sans_serif.ttf) file there. Then you can make something like this:
fonts_path = os.path.join(os.path.dirname(os.path.dirname(__file__)), 'fonts')
font = ImageFont.truetype(os.path.join(fonts_path, 'sans_serif.ttf'), 24)
For those of you wishing not to use an external library, and prefer not to use OleDB, see the example below. Everything I found was either OleDB, external library, or simply splitting based on a comma! For my case OleDB was not working so I wanted something different.
I found an article by MarkJ that referenced the Microsoft.VisualBasic.FileIO.TextFieldParser method as seen here. The article is written in VB and doesn't return a datatable, so see my example below.
public static DataTable LoadCSV(string path, bool hasHeader)
{
DataTable dt = new DataTable();
using (var MyReader = new Microsoft.VisualBasic.FileIO.TextFieldParser(path))
{
MyReader.TextFieldType = Microsoft.VisualBasic.FileIO.FieldType.Delimited;
MyReader.Delimiters = new String[] { "," };
string[] currentRow;
//'Loop through all of the fields in the file.
//'If any lines are corrupt, report an error and continue parsing.
bool firstRow = true;
while (!MyReader.EndOfData)
{
try
{
currentRow = MyReader.ReadFields();
//Add the header columns
if (hasHeader && firstRow)
{
foreach (string c in currentRow)
{
dt.Columns.Add(c, typeof(string));
}
firstRow = false;
continue;
}
//Create a new row
DataRow dr = dt.NewRow();
dt.Rows.Add(dr);
//Loop thru the current line and fill the data out
for(int c = 0; c < currentRow.Count(); c++)
{
dr[c] = currentRow[c];
}
}
catch (Microsoft.VisualBasic.FileIO.MalformedLineException ex)
{
//Handle the exception here
}
}
}
return dt;
}
First create a real, permanent table as a template that has the required layout for the returned temporary table, using a naming convention that identifies it as a template and links it symbolically to the SP, eg tmp_SPName_Output. This table will never contain any data.
In the SP, use INSERT to load data into a temp table following the same naming convention, e.g. #SPName_Output which is assumed to exist. You can test for its existence and return an error if it does not.
Before calling the sp use this simple select to create the temp table:
SELECT TOP(0) * INTO #SPName_Output FROM tmp_SPName_Output;
EXEC SPName;
-- Now process records in #SPName_Output;
This has these distinct advantages:
Mac OS X is Unix, Objective-C is C superset, so you can just use old-school fopen
and fgets
from <stdio.h>
. It's guaranteed to work.
[NSString stringWithUTF8String:buf]
will convert C string to NSString
. There are also methods for creating strings in other encodings and creating without copying.
If you are pushing from one remote origin to another, you can use this:
git push newremote refs/remotes/oldremote/*:refs/heads/*
This worked for me. Reffer to this: https://www.metaltoad.com/blog/git-push-all-branches-new-remote
The default credentials are:
login: admin
password: admin
But if you use EAP these credentials are turned off by default and there is no active user (security reasons :)). If you want to turn on these users, you have to edit the following file in your current profile: ./deploy/management/console-mgr.sar/web-console.war/WEB-INF/classes/web-console-users.properties
. It should be enough to remove the #
sign from the line with the user.
If you want to create a new user, don't forget to set up the correct groups in web-console-roles.properties
file.
You can easily find information where these information are stored: just open the ./conf/login-config.xml
file and find the proper security domain definition. In the case of the Web Console application, it will be web-console
policy.
Also if you want to have access to JMX, you have unlock JMX Console. Just check the following files in the conf/props/
directory (in your profile): jmx-console-users.properties
and jmx-console-roles.properties
.
Adding to assylias's answer - assylias shows us D.ITEMS is a method that returns an array. Knowing that, we don't need the variant array a(i) [See caveat below]. We just need to use the proper array syntax.
For i = 0 To d.Count - 1
s = d.Items()(i)
Debug.Print s
Next i()
KEYS works the same way
For i = 0 To d.Count - 1
Debug.Print d.Keys()(i), d.Items()(i)
Next i
This syntax is also useful for the SPLIT function which may help make this clearer. SPLIT also returns an array with lower bounds at 0. Thus, the following prints "C".
Debug.Print Split("A,B,C,D", ",")(2)
SPLIT is a function. Its parameters are in the first set of parentheses. Methods and Functions always use the first set of parentheses for parameters, even if no parameters are needed. In the example SPLIT returns the array {"A","B","C","D"}. Since it returns an array we can use a second set of parentheses to identify an element within the returned array just as we would any array.
Caveat: This shorter syntax may not be as efficient as using the variant array a() when iterating through the entire dictionary since the shorter syntax invokes the dictionary's Items method with each iteration. The shorter syntax is best for plucking a single item by number from a dictionary.
I had a simple code for Spring Cloud Config
like this:
In application.properties
spring.data.mongodb.db1=mongodb://[email protected]
spring.data.mongodb.db2=mongodb://[email protected]
@Bean(name = "mongoConfig")
@ConfigurationProperties(prefix = "spring.data.mongodb")
public Map<String, Map<String, String>> mongoConfig() {
return new HashMap();
}
@Autowired
@Qualifier(value = "mongoConfig")
private Map<String, String> mongoConfig;
@Bean(name = "mongoTemplates")
public HashMap<String, MongoTemplate> mongoTemplateMap() throws UnknownHostException {
HashMap<String, MongoTemplate> mongoTemplates = new HashMap<>();
for (Map.Entry<String, String>> entry : mongoConfig.entrySet()) {
String k = entry.getKey();
String v = entry.getValue();
MongoTemplate template = new MongoTemplate(new SimpleMongoDbFactory(new MongoClientURI(v)));
mongoTemplates.put(k, template);
}
return mongoTemplates;
}
class Student(object):
name = ""
age = 0
major = ""
# The class "constructor" - It's actually an initializer
def __init__(self, name, age, major):
self.name = name
self.age = age
self.major = major
def make_student(name, age, major):
student = Student(name, age, major)
return student
Note that even though one of the principles in Python's philosophy is "there should be one—and preferably only one—obvious way to do it", there are still multiple ways to do this. You can also use the two following snippets of code to take advantage of Python's dynamic capabilities:
class Student(object):
name = ""
age = 0
major = ""
def make_student(name, age, major):
student = Student()
student.name = name
student.age = age
student.major = major
# Note: I didn't need to create a variable in the class definition before doing this.
student.gpa = float(4.0)
return student
I prefer the former, but there are instances where the latter can be useful – one being when working with document databases like MongoDB.
' \r ' means carriage return.
The \r means nothing special as a consequence.For character-mode terminals (typically emulating even-older printing ones as above), in raw mode, \r and \n act similarly (except both in terms of the cursor, as there is no carriage or roller . Historically a \n was used to move the carriage down, while the \r was used to move the carriage back to the left side of the screen.
Using React with Typescript you get an error as the function must return a react element, not void
. So I did it this way using the Route render method (and using React router v4):
redirectToHomePage = (): null => {
window.location.reload();
return null;
};
<Route exact path={'/'} render={this.redirectToHomePage} />
Where you could instead also use window.location.assign()
, window.location.replace()
etc
You can get the all record of the date '2016-07-14' by using it
whereDate('date','=','2016-07-14')
Or use the another code for dynamic date
whereDate('date',$date)
After you do express in your terminal, then do
npm install
To install all the dependencies.
Then you can do node app to run the server.
There is a big difference between an empty collection and a null reference to a collection.
When you use foreach
, internally, this is calling the IEnumerable's GetEnumerator() method. When the reference is null, this will raise this exception.
However, it is perfectly valid to have an empty IEnumerable
or IEnumerable<T>
. In this case, foreach will not "iterate" over anything (since the collection is empty), but it will also not throw, since this is a perfectly valid scenario.
Edit:
Personally, if you need to work around this, I'd recommend an extension method:
public static IEnumerable<T> AsNotNull<T>(this IEnumerable<T> original)
{
return original ?? Enumerable.Empty<T>();
}
You can then just call:
foreach (int i in returnArray.AsNotNull())
{
// do some more stuff
}
Short answer:
ALTER SCHEMA new_schema TRANSFER old_schema.table_name
I can confirm that the data in the table remains intact, which is probably quite important :)
Long answer as per MSDN docs,
ALTER SCHEMA schema_name
TRANSFER [ Object | Type | XML Schema Collection ] securable_name [;]
If it's a table (or anything besides a Type or XML Schema collection), you can leave out the word Object since that's the default.
to check if a date is today's date or not only check for dates not time included with that so make time 00:00:00 and use the code below
Calendar c = Calendar.getInstance();
// set the calendar to start of today
c.set(Calendar.HOUR_OF_DAY, 0);
c.set(Calendar.MINUTE, 0);
c.set(Calendar.SECOND, 0);
c.set(Calendar.MILLISECOND, 0);
Date today = c.getTime();
// or as a timestamp in milliseconds
long todayInMillis = c.getTimeInMillis();
int dayOfMonth = 24;
int month = 4;
int year =2013;
// reuse the calendar to set user specified date
c.set(Calendar.YEAR, year);
c.set(Calendar.MONTH, month - 1);
c.set(Calendar.DAY_OF_MONTH, dayOfMonth);
c.set(Calendar.HOUR_OF_DAY, 0);
c.set(Calendar.MINUTE, 0);
c.set(Calendar.SECOND, 0);
c.set(Calendar.MILLISECOND, 0);
// and get that as a Date
Date dateSpecified = c.getTime();
// test your condition
if (dateSpecified.before(today)) {
Log.v(" date is previou")
} else if (dateSpecified.equal(today)) {
Log.v(" date is today ")
}
else if (dateSpecified.after(today)) {
Log.v(" date is future date ")
}
Hope it will help....
In Visual Basic, you can call a parameterless method without the braces (()
). In C#, they're mandatory. So you should write:
String guid = System.Guid.NewGuid().ToString();
Without the braces, you're assigning the method itself (instead of its result) to the variable guid
, and obviously the method cannot be converted to a String
, hence the error.
Go to Manifest -> Merged Manifest Tab (bottom of screen).
On the right panel, if you have any error, resolve it !
This was the solution for me (error with tool:replace not needeed)
You need to recompile ffmpeg (from source) so that it supports x264. If you follow the instructions in this page, then you will be able to peform any kind of conversion you want.
When numbers, dates and times are formatted into strings or parsed from strings a culture is used to determine how it is done. E.g. in the dominant en-US
culture you have these string representations:
In my culture (da-DK
) the values have this string representation:
In the Windows operating system the user may even customize how numbers and date/times are formatted and may also choose another culture than the culture of his operating system. The formatting used is the choice of the user which is how it should be.
So when you format a value to be displayed to the user using for instance ToString
or String.Format
or parsed from a string using DateTime.Parse
or Decimal.Parse
the default is to use the CultureInfo.CurrentCulture
. This allows the user to control the formatting.
However, a lot of string formatting and parsing is actually not strings exchanged between the application and the user but between the application and some data format (e.g. an XML or CSV file). In that case you don't want to use CultureInfo.CurrentCulture
because if formatting and parsing is done with different cultures it can break. In that case you want to use CultureInfo.InvariantCulture
(which is based on the en-US
culture). This ensures that the values can roundtrip without problems.
The reason that ReSharper gives you the warning is that some application writers are unaware of this distinction which may lead to unintended results but they never discover this because their CultureInfo.CurrentCulture
is en-US
which has the same behavior as CultureInfo.InvariantCulture
. However, as soon as the application is used in another culture where there is a chance of using one culture for formatting and another for parsing the application may break.
So to sum it up:
CultureInfo.CurrentCulture
(the default) if you are formatting or parsing a user string.CultureInfo.InvariantCulture
if you are formatting or parsing a string that should be parseable by a piece of software.It will be increasing because you have a need for temporary storage space, possibly due to a cartesian product or a large sort operation.
The dynamic performance view V$TEMPSEG_USAGE
will help diagnose the cause.

The consumable media types of the mapped request, narrowing the primary mapping.
the producer is used to narrow the primary mapping, you send request should specify the exact header to match it.
The overall dimensions of a range are in its Width
and Height
properties.
Dim r As Range
Set r = ActiveSheet.Range("A4:H12")
Debug.Print r.Width
Debug.Print r.Height
If the first column is always the same size (including the spaces), then you can just take those characters (via LEFT
) and clean up the spaces (with RTRIM
):
SELECT RTRIM(LEFT(YourColumn, YourColumnSize))
Alternatively, you can extract the second (or third, etc.) column (using SUBSTRING
):
SELECT RTRIM(SUBSTRING(YourColumn, PreviousColumnSizes, YourColumnSize))
One benefit of this approach (especially if YourColumn
is the result of a computation) is that YourColumn
is only specified once.
This should fix it...

Java doesn't natively allow building of an exe, that would defeat its purpose of being cross-platform.
AFAIK, these are your options:
Make a runnable JAR. If the system supports it and is configured appropriately, in a GUI, double clicking the JAR will launch the app. Another option would be to write a launcher shell script/batch file which will start your JAR with the appropriate parameters
There also executable wrappers - see How can I convert my Java program to an .exe file?
As noted by other answers, the general solution is to use an index expression in an assignment of the special form:
v, ok = a[x]
v, ok := a[x]
var v, ok = a[x]
var v, ok T = a[x]
This is nice and clean. It has some restrictions though: it must be an assignment of special form. Right-hand side expression must be the map index expression only, and the left-hand expression list must contain exactly 2 operands, first to which the value type is assignable, and a second to which a bool
value is assignable. The first value of the result of this special form will be the value associated with the key, and the second value will tell if there is actually an entry in the map with the given key (if the key exists in the map). The left-hand side expression list may also contain the blank identifier if one of the results is not needed.
It's important to know that if the indexed map value is nil
or does not contain the key, the index expression evaluates to the zero value of the value type of the map. So for example:
m := map[int]string{}
s := m[1] // s will be the empty string ""
var m2 map[int]float64 // m2 is nil!
f := m2[2] // f will be 0.0
fmt.Printf("%q %f", s, f) // Prints: "" 0.000000
Try it on the Go Playground.
So if we know that we don't use the zero value in our map, we can take advantage of this.
For example if the value type is string
, and we know we never store entries in the map where the value is the empty string (zero value for the string
type), we can also test if the key is in the map by comparing the non-special form of the (result of the) index expression to the zero value:
m := map[int]string{
0: "zero",
1: "one",
}
fmt.Printf("Key 0 exists: %t\nKey 1 exists: %t\nKey 2 exists: %t",
m[0] != "", m[1] != "", m[2] != "")
Output (try it on the Go Playground):
Key 0 exists: true
Key 1 exists: true
Key 2 exists: false
In practice there are many cases where we don't store the zero-value value in the map, so this can be used quite often. For example interfaces and function types have a zero value nil
, which we often don't store in maps. So testing if a key is in the map can be achieved by comparing it to nil
.
Using this "technique" has another advantage too: you can check existence of multiple keys in a compact way (you can't do that with the special "comma ok" form). More about this: Check if key exists in multiple maps in one condition
Getting the zero value of the value type when indexing with a non-existing key also allows us to use maps with bool
values conveniently as sets. For example:
set := map[string]bool{
"one": true,
"two": true,
}
fmt.Println("Contains 'one':", set["one"])
if set["two"] {
fmt.Println("'two' is in the set")
}
if !set["three"] {
fmt.Println("'three' is not in the set")
}
It outputs (try it on the Go Playground):
Contains 'one': true
'two' is in the set
'three' is not in the set

Another case I just had - when the request size is bigger than the request size set in IIS as a limit, then you can get that error too.
Check the IIS request limit and increase it if it's lower than you need. Here is how you can check and change the IIS request limit:
I just found also another thread in stack IIS 7.5 hosted WCF service throws EndpointNotFoundException with 404 only for large requests
extension UIApplication {
/// The top most view controller
static var topMostViewController: UIViewController? {
return UIApplication.shared.keyWindow?.rootViewController?.visibleViewController
}
}
extension UIViewController {
/// The visible view controller from a given view controller
var visibleViewController: UIViewController? {
if let navigationController = self as? UINavigationController {
return navigationController.topViewController?.visibleViewController
} else if let tabBarController = self as? UITabBarController {
return tabBarController.selectedViewController?.visibleViewController
} else if let presentedViewController = presentedViewController {
return presentedViewController.visibleViewController
} else {
return self
}
}
}
With this you can easily get the top post view controller like so
let viewController = UIApplication.topMostViewController
One thing to note is that if there's a UIAlertController currently being displayed, UIApplication.topMostViewController
will return a UIAlertController
.
So do the following ,
Lets say your branch name is my_branch and this has the extra commits.
git checkout -b my_branch_with_extra_commits
(Keeping this branch saved under a different name)gitk
(Opens git console)git checkout my_branch
gitk
(This will open the git console )reset branch to here
" git pull --rebase origin branch_name_to _merge_to
git cherry-pick <SHA you copied in step 3. >
Now look at the local branch commit history and make sure everything looks good.
//insert this php code, at the end after your closing html tag.
<?php
//setting connection to database
$con = mysqli_connect("localhost","your-username","your-

if(isset($_POST['submit_button'])){
$txt_area = $_POST['update'];
$Our_query= "INSERT INTO your-table-name (field1name, field2name)
VALUES ('abc','def')"; // values should match data
// type to field names
$insert_query = mysqli_query($con, $Our_query);
if($insert_query){
echo "<script>window.open('form.php','_self') </script>";
// supposing form.php is where you have created this form
}
} //if statement close
?>
Hope this helps.
Go to command prompt and enter the command,
net user <username>
Will show your local group memberships.
If you're on a domain, use localgroup instead:
net localgroup Administrators or net localgroup [Admin group name]
Check the list of local groups with localgroup on its own.
net localgroup
You should not use your domain models
in your views. ViewModels
are the correct way to do it.
You need to map your domain model's necessary fields to viewmodel and then use this viewmodel in your controllers. This way you will have the necessery abstraction in your application.
If you never heard of viewmodels, take a look at this.
You could remove the folder and update the parent directory before committing:
rm -r some_dir
svn update some_dir_parent
HTML5 basically behaves as if the trailing slash is not there. There is no such thing as a self-closing tag in HTML5 syntax.
Self-closing tags on non-void elements like <p/>
, <div/>
will not work at all. The trailing slash will be ignored, and these will be treated as opening tags. This is likely to lead to nesting problems.
This is true regardless of whether there is whitespace in front of the slash: <p />
and <div />
also won't work for the same reason.
Self-closing tags on void elements like <br/>
or <img src="" alt=""/>
will work, but only because the trailing slash is ignored, and in this case that happens to result in the correct behaviour.
The result is, anything that worked in your old "XHTML 1.0 served as text/html" will continue to work as it did before: trailing slashes on non-void tags were not accepted there either whereas the trailing slash on void elements worked.
One more note: it is possible to represent an HTML5 document as XML, and this is sometimes dubbed "XHTML 5.0". In this case the rules of XML apply and self-closing tags will always be handled. It would always need to be served with an XML mime type.

After configuring this plug-in, running mvn package
will produce two jars: one containing just the project classes, and a second fat jar with all dependencies with the suffix "-jar-with-dependencies".
if you want correct classpath
setup at runtime then also add following plugin
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>fully.qualified.MainClass</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
For spring boot application use just following plugin (choose appropriate version of it)
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<fork>true</fork>
<mainClass>${start-class}</mainClass>

Without sharex=True, sharey=True
you get:
With it you should get it nicer:
fig, axes2d = plt.subplots(nrows=3, ncols=3,
sharex=True, sharey=True,
figsize=(6,6))
for i, row in enumerate(axes2d):
for j, cell in enumerate(row):
cell.imshow(np.random.rand(32,32))
plt.tight_layout()
But if you want to add additional labels, you should add them only to the edge plots:
fig, axes2d = plt.subplots(nrows=3, ncols=3,
sharex=True, sharey=True,
figsize=(6,6))
for i, row in enumerate(axes2d):
for j, cell in enumerate(row):
cell.imshow(np.random.rand(32,32))
if i == len(axes2d) - 1:
cell.set_xlabel("noise column: {0:d}".format(j + 1))
if j == 0:
cell.set_ylabel("noise row: {0:d}".format(i + 1))
plt.tight_layout()
Adding label for each plot would spoil it (maybe there is a way to automatically detect repeated labels, but I am not aware of one).
