I am not experienced at all so feel free to correct things. However, I tried all these answers, but always had a problem in some screen. So I tried the following that worked for me and looks as I want it in almost all screens with the exception of mobile.
<div class="wrapper">
<div id="Section-Title">
<div id="h2"> YOUR TITLE
<div id="line"><hr></div>
</div>
</div>
</div>
CSS:
.wrapper{
background:#fff;
max-width:100%;
margin:20px auto;
padding:50px 5%;}
#Section-Title{
margin: 2% auto;
width:98%;
overflow: hidden;}
#h2{
float:left;
width:100%;
position:relative;
z-index:1;
font-family:Arial, Helvetica, sans-serif;
font-size:1.5vw;}
#h2 #line {
display:inline-block;
float:right;
margin:auto;
margin-left:10px;
width:90%;
position:absolute;
top:-5%;}
#Section-Title:after{content:""; display:block; clear:both; }
.wrapper:after{content:""; display:block; clear:both; }
SELECT
distributor_id,
COUNT(*) AS TOTAL,
COUNT(IF(level='exec',1,null)),
COUNT(IF(level='personal',1,null))
FROM sometable;
COUNT
only counts non null
values and the DECODE
will return non null value 1
only if your condition is satisfied.
There's a solution that does not require one to publish the spreadsheet. However, the sheet does need to be 'Shared'. More specifically, one needs to share the sheet in a manner where anyone with the link can access the spreadsheet. Once this is done, one can use the Google Sheets HTTP API.
First up, you need an Google API key. Head here: https://developers.google.com/places/web-service/get-api-key NB. Please be aware of the security ramifications of having an API key made available to the public: https://support.google.com/googleapi/answer/6310037
https://sheets.googleapis.com/v4/spreadsheets/{spreadsheetId}/?key={yourAPIKey}&includeGridData=true
https://sheets.googleapis.com/v4/spreadsheets/{spreadsheetId}/?key={yourAPIKey}
https://sheets.googleapis.com/v4/spreadsheets/{spreadsheetId}/values/{sheetName}!{cellRange}?key={yourAPIKey}
Now armed with this information, one can use AJAX to retrieve data and then manipulate it in JavaScript. I would recommend using axios.
var url = "https://sheets.googleapis.com/v4/spreadsheets/{spreadsheetId}/?key={yourAPIKey}&includeGridData=true";
axios.get(url)
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log(error);
});
Try like this as well
covertPostSub("/xyz/test.jsp","?param1=param1¶m2=param2","_self","true");
covertPostSub("/xyz/test.jsp","?param1=param1¶m2=param2","_blank","true");
var convPop = null;
function covertPostSub(action,paramsTosend,targetIframe,isWindow){
var Popup = null;
var form = document.createElement("form");
form.setAttribute("method", "POST");
form.setAttribute("id","TheForm");
form.setAttribute("action", action);
form.setAttribute("target", targetIframe);
var params = paramsTosend;
params = params.substring(1, params.length);
params = params.split("&");
for(var key=0; key<params.length; key++) {
var sa = params[key];
sa = sa.split("=");
var xs = (sa[1]);
if(params.hasOwnProperty(key)) {
var hiddenField = document.createElement("input");
hiddenField.setAttribute("type", "hidden");
hiddenField.setAttribute("name", sa[0]);
hiddenField.setAttribute("value",xs);
form.appendChild(hiddenField);
}
}
document.body.appendChild(form);
form.style.display = "none";
if(isWindow){
window.open('', "formpopup","width=900,height=590,toolbar=no,scrollbars=yes,resizable=no,location=0,directories=0,status=1,menubar=0,left=60,top=60");
form.target = 'formpopup';
form.submit();
}else{
form.submit();
}
}
String start = "12:00:00";
String end = "02:05:00";
SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss");
Date date1 = format.parse(start);
Date date2 = format.parse(end);
long difference = date2.getTime() - date1.getTime();
int minutes = (int) TimeUnit.MILLISECONDS.toMinutes(difference);
if(minutes<0)minutes += 1440;
Now minutes will be the correct duration between two time (in minute).
All these answers around here, as well as the answers in this question, suggest that loading absolute URLs, like "/foo/bar.properties" treated the same by class.getResourceAsStream(String)
and class.getClassLoader().getResourceAsStream(String)
. This is NOT the case, at least not in my Tomcat configuration/version (currently 7.0.40).
MyClass.class.getResourceAsStream("/foo/bar.properties"); // works!
MyClass.class.getClassLoader().getResourceAsStream("/foo/bar.properties"); // does NOT work!
Sorry, I have absolutely no satisfying explanation, but I guess that tomcat does dirty tricks and his black magic with the classloaders and cause the difference. I always used class.getResourceAsStream(String)
in the past and haven't had any problems.
PS: I also posted this over here
Here is my solution for the problem, I was building a WP site, so there is a little php code here. But the key is scrollwheel: false,
in the map object.
function initMap() {
var uluru = {lat: <?php echo $latitude; ?>, lng: <?php echo $Longitude; ?>};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 18,
scrollwheel: false,
center: uluru
});
var marker = new google.maps.Marker({
position: uluru,
map: map
});
}
Hope this will help. Cheers
Date()
is not part of jQuery
, it is one of JavaScript's features.
See the documentation on Date object.
You can do it like that:
var d = new Date();
var month = d.getMonth()+1;
var day = d.getDate();
var output = d.getFullYear() + '/' +
(month<10 ? '0' : '') + month + '/' +
(day<10 ? '0' : '') + day;
See this jsfiddle for a proof.
The code may look like a complex one, because it must deal with months & days being represented by numbers less than 10
(meaning the strings will have one char instead of two). See this jsfiddle for comparison.
Some addition to the previous answers. It is nice to regulate the density of the polygon to avoid obscuring the data points.
library(MASS)
attach(Boston)
lm.fit2 = lm(medv~poly(lstat,2))
plot(lstat,medv)
new.lstat = seq(min(lstat), max(lstat), length.out=100)
preds <- predict(lm.fit2, newdata = data.frame(lstat=new.lstat), interval = 'prediction')
lines(sort(lstat), fitted(lm.fit2)[order(lstat)], col='red', lwd=3)
polygon(c(rev(new.lstat), new.lstat), c(rev(preds[ ,3]), preds[ ,2]), density=10, col = 'blue', border = NA)
lines(new.lstat, preds[ ,3], lty = 'dashed', col = 'red')
lines(new.lstat, preds[ ,2], lty = 'dashed', col = 'red')
Please note that you see the prediction interval on the picture, which is several times wider than the confidence interval. You can read here the detailed explanation of those two types of interval estimates.
use DateTime.ParseExact
string strDate = "24/01/2013";
DateTime date = DateTime.ParseExact(strDate, "dd/MM/YYYY", null)
null
will use the current culture, which is somewhat dangerous. Try to supply a specific culture
DateTime date = DateTime.ParseExact(strDate, "dd/MM/YYYY", CultureInfo.InvariantCulture)

Here is the utility I wrote to generate a simple setup.py file (template) with useful comments and links. I hope, it will be useful.
sudo pip install setup-py-cli
To generate setup.py file just type in the terminal.
setup-py
Now setup.py file should occur in the current directory.
from distutils.core import setup
from setuptools import find_packages
import os
# User-friendly description from README.md
current_directory = os.path.dirname(os.path.abspath(__file__))
try:
with open(os.path.join(current_directory, 'README.md'), encoding='utf-8') as f:
long_description = f.read()
except Exception:
long_description = ''

Don't serialize FormData
with POST
ing to server. Do this:
this.uploadFileToUrl = function(file, title, text, uploadUrl){
var payload = new FormData();
payload.append("title", title);
payload.append('text', text);
payload.append('file', file);
return $http({
url: uploadUrl,
method: 'POST',
data: payload,
//assign content-type as undefined, the browser
//will assign the correct boundary for us
headers: { 'Content-Type': undefined},
//prevents serializing payload. don't do it.
transformRequest: angular.identity
});
}
Then use it:
MyService.uploadFileToUrl(file, title, text, uploadUrl).then(successCallback).catch(errorCallback);

There's absolutely nothing wrong with including the entirety of jQuery within your Greasemonkey script. Just take the source, and place it at the top of your user script. No need to make a script tag, since you're already executing JavaScript!
The user only downloads the script once anyways, so size of script is not a big concern. In addition, if you ever want your Greasemonkey script to work in non-GM environments (such as Opera's GM-esque user scripts, or Greasekit on Safari), it'll help not to use GM-unique constructs such as @require.
As a developer of SpeedView: GPS speedometer for Android, I must have tried every possible solution to this problem, all with the same negative result. Let's reiterate what doesn't work:
So here's the only working solution I found, and the one that I actually use in my app. Let's say we have this simple class that implements the GpsStatus.Listener:
private class MyGPSListener implements GpsStatus.Listener {
public void onGpsStatusChanged(int event) {
switch (event) {
case GpsStatus.GPS_EVENT_SATELLITE_STATUS:
if (mLastLocation != null)
isGPSFix = (SystemClock.elapsedRealtime() - mLastLocationMillis) < 3000;
if (isGPSFix) { // A fix has been acquired.
// Do something.
} else { // The fix has been lost.
// Do something.
}
break;
case GpsStatus.GPS_EVENT_FIRST_FIX:
// Do something.
isGPSFix = true;
break;
}
}
}
OK, now in onLocationChanged() we add the following:
@Override
public void onLocationChanged(Location location) {
if (location == null) return;
mLastLocationMillis = SystemClock.elapsedRealtime();
// Do something.
mLastLocation = location;
}
And that's it. Basically, this is the line that does it all:
isGPSFix = (SystemClock.elapsedRealtime() - mLastLocationMillis) < 3000;
You can tweak the millis value of course, but I'd suggest to set it around 3-5 seconds.
This actually works and although I haven't looked at the source code that draws the native GPS icon, this comes close to replicating its behaviour. Hope this helps someone.
I use the jQuery clueTip plugin for this.
If set is sufficient, ConcurrentSkipListSet might be used. (Its implementation is based on ConcurrentSkipListMap which implements a skip list.)
The expected average time cost is log(n) for the contains, add, and remove operations; the size method is not a constant-time operation.
The timeout configuration needs to be set at the client level, so the configuration I was setting in the web.config had no effect, the WCF test tool has its own configuration and there is where you need to set the timeout.
If you have gitk (try running "gitk --all from your git command line"), it's simple. Just run it, select the commit you want to rollback to (right-click), and select "Reset master branch to here". If you have no uncommited changes, chose the "hard" option.
I am assuming that active events in a time period means at least one day of the event falls inside the time period. This is a simple "find overlapping dates" problem and there is a generic solution:
-- [@d1, @d2] is the date range to check against
SELECT * FROM events WHERE @d2 >= start AND end >= @d1
Some tests:
-- list of events
SELECT * FROM events;

Javadocs don't offer any special tools for external links, so you should just use standard html:
See <a href="http://groversmill.com/">Grover's Mill</a> for a history of the
Martian invasion.
or
@see <a href="http://groversmill.com/">Grover's Mill</a> for a history of
the Martian invasion.
Don't use {@link ...}
or {@linkplain ...}
because these are for links to the javadocs of other classes and methods.

Changed the braced iterators, good call. Also, call this function with a reverse iterator.
You can probably do something like this:
#!/bin/bash
HISTFILE=~/.bash_history # if you are running it in a
# non interactive shell history would not work else
set -o history
for i in `seq $1 $2`;
do
history -d $i
done
history -w
Where you will evoke like this:
./nameOfYourScript 563 514
Notice I haven't put any error checking in for the bounds. I'll leave that as an exercise to the reader.

Is also an option. Note, however, that it skips any wrapper defined for your form builder.
Attach an event handler to the submit event of the form. Make sure it cancels the default action.
Quirks Mode has a guide to event handlers, but you would probably be better off using a library to simplify the code and iron out the differences between browsers. All the major ones (such as YUI and jQuery) include event handling features, and there is a large collection of tiny event libraries.
Here is how you would do it in YUI 3:
<script src="http://yui.yahooapis.com/3.4.1/build/yui/yui-min.js"></script>
<script>
YUI().use('event', function (Y) {
Y.one('form').on('submit', function (e) {
// Whatever else you want to do goes here
e.preventDefault();
});
});
</script>

I had the same problem, and the solution ended up being adding my local machine's IP to the list of inbound rules in the active security group. In the inbound dialog below, enter 22 in the port range, your local IP/32 in the source field, and leave 'custom tcp rule' in the dropdown.

To unify all of the screens to show same element sizes including font size: - Design the UI on one screen size with whatever sizes you find appropriate during the design i.e. TextView font size is 14dp on default screen size with 4'6 inches.
Programmatically calculate the physical screen size of the other phones i.e. 5'2 inches of other phones/screens.
Use a formula to calculate the percentage difference between the 2 screens. i.e. what's the % difference between 4'6 and 5'2.
Calculate the pixel difference between the 2 TextViews based on the above formula.
Get the actual size (in pixels) of the TextView font-size and apply the pixels difference (you calculated earlier) to the default font-size.
With this way you can apply dynamic aspect ratio to all of screen sizes and the result is great. You'll have identical layout and sizes on each screen.
It can be a bit tricky at first but totally achieves the goal once you figure the formula out. With this method you don't need to make multiple layouts just to fit different screen sizes.
The simplest solution here is to change
var newcurrentpageTemp = $(this).attr("id") + 1;//Get the id from the hyperlink
to:
var newcurrentpageTemp = (($(this).attr("id")) * 1) + 1;//Get the id from the hyperlink
On the above example I kept losing the values, I think that delaying the Validation will allow the new data types to be saved as part of the meta data.
On the connection Manager for 'Excel Connection Manager' set the Delay Validation to False from the Properties.
Then on the data flow Destination task for Excel set the ValidationExternalMetaData to False, again from the properties.
This will now allow you to right click on the Excel Destination Task and go to Advanced Editor for Excel Destination --> far right tab - Input and Output Properties. In the External Columns folder section you will be able to now change the Data Types and Length values of the problematic columns and this can now be saved.
Good Luck!

Two ways to delete the image from public folder without changing laravel filesystems config file or messing with pure php unlink function:
- Using the default local storage you need to specify public subfolder:
Storage::delete('public/'.$image_path);
- Use public storage directly:
Storage::disk('public')->delete($image_path);
I would suggest second way as the best one.
Hope this help other people.

It is important to remember when using defaultdict and similar nested dict modules such as nested_dict
, that looking up a nonexistent key may inadvertently create a new key entry in the dict and cause a lot of havoc.
Here is a Python3 example with nested_dict
module:
import nested_dict as nd
nest = nd.nested_dict()
nest['outer1']['inner1'] = 'v11'
nest['outer1']['inner2'] = 'v12'
print('original nested dict: \n', nest)
try:
nest['outer1']['wrong_key1']
except KeyError as e:
print('exception missing key', e)
print('nested dict after lookup with missing key. no exception raised:\n', nest)
# Instead, convert back to normal dict...
nest_d = nest.to_dict(nest)
try:
print('converted to normal dict. Trying to lookup Wrong_key2')
nest_d['outer1']['wrong_key2']
except KeyError as e:
print('exception missing key', e)
else:
print(' no exception raised:\n')
# ...or use dict.keys to check if key in nested dict
print('checking with dict.keys')
print(list(nest['outer1'].keys()))
if 'wrong_key3' in list(nest.keys()):
print('found wrong_key3')
else:
print(' did not find wrong_key3')
Output is:
original nested dict: {"outer1": {"inner2": "v12", "inner1": "v11"}}
nested dict after lookup with missing key. no exception raised:
{"outer1": {"wrong_key1": {}, "inner2": "v12", "inner1": "v11"}}
converted to normal dict.
Trying to lookup Wrong_key2
exception missing key 'wrong_key2'
checking with dict.keys
['wrong_key1', 'inner2', 'inner1']
did not find wrong_key3
To randomly select 20 rows I think you'd be better off selecting the lot of them randomly ordered and selecting the first 20 of that set.
Something like:
Select *
from (select *
from table
order by dbms_random.value) -- you can also use DBMS_RANDOM.RANDOM
where rownum < 21;
Best used for small tables to avoid selecting large chunks of data only to discard most of it.

Yes, we can use jQuery in ReactJs. Here I will tell how we can use it using npm.
step 1: Go to your project folder where the package.json
file is present via using terminal using cd command.
step 2: Write the following command to install jquery using npm : npm install jquery --save
step 3: Now, import $
from jquery
into your jsx file where you need to use.
Example:
write the below in index.jsx
import React from 'react';
import ReactDOM from 'react-dom';
import $ from 'jquery';
// react code here
$("button").click(function(){
$.get("demo_test.asp", function(data, status){
alert("Data: " + data + "\nStatus: " + status);
});
});
// react code here
write the below in index.html
<!DOCTYPE html>
<html>
<head>
<script src="index.jsx"></script>
<!-- other scripting files -->
</head>
<body>
<!-- other useful tags -->
<div id="div1">
<h2>Let jQuery AJAX Change This Text</h2>
</div>
<button>Get External Content</button>
</body>

Another important thing you need to note with ".addEventListener is not a function" error is that the error might be coming a result of assigning it a wrong object eg consider
let myImages = ['images/pic1.jpg','images/pic2.jpg','images/pic3.jpg','images/pic4.jpg','images/pic5.jpg'];
let i = 0;
while(i < myImages.length){
const newImage = document.createElement('img');
newImage.setAttribute('src',myImages[i]);
thumbBar.appendChild(newImage);
//Code just below will bring the said error
myImages[i].addEventListener('click',fullImage);
//Code just below execute properly
newImage.addEventListener('click',fullImage);

In the code Above I am basically assigning images to a div element in my html dynamically using javascript. I've done this by writing the images in an array and looping them through a while loop and adding all of them to the div element.
I've then added a click event listener for all images.
The code "myImages[i].addEventListener('click',fullImage);" will give you an error of "addEventListener is not a function" because I am chaining an addEventListener to an array object which does not have the addEventListener() function.
However for the code "newImage.addEventListener('click',fullImage);" it executes properly because the newImage object has access the function addEventListener() while the array object does not.

If you work on Windows and use PowerShell (like me), you could use the following line to capture the stdout
and stderr
:
docker logs <containerId> | Out-File 'C:/dev/mylog.txt'
I hope it helps someone!
If you want to log errors from web-page, you should use WebChromeClient
and override its onConsoleMessage
:
webView.settings.apply {
javaScriptEnabled = true
javaScriptCanOpenWindowsAutomatically = true
domStorageEnabled = true
}
webView.webViewClient = WebViewClient()
webView.webChromeClient = MyWebChromeClient()
private class MyWebChromeClient : WebChromeClient() {
override fun onConsoleMessage(consoleMessage: ConsoleMessage): Boolean {
Timber.d("${consoleMessage.message()}")
Timber.d("${consoleMessage.lineNumber()} ${consoleMessage.sourceId()}")
return super.onConsoleMessage(consoleMessage)
}
}
Well its little strange but I guess you have to add a resource to your "Copy Bundle Resources" phase of your test target to make it load all headers from your main app target. In my case, I added main.storyboard
and it took care of the error.
You may try this example:
<form>_x000D_
<h1>Hello! I'm duke! What's you name?</h1>_x000D_
<input type="text" name="user">_x000D_
<br>_x000D_
<br>_x000D_
<input type="submit" value="submit"> _x000D_
<input type="reset">_x000D_
</form>_x000D_
<h1>Hello ${param.user}</h1> _x000D_
<!-- its Expression Language -->

I have a Mac, but luckily this should work the same way:
pip
is a command-line thing. You don't run it in python.
For example, on my Mac, I just say:
$pip install somelib
pretty easy!

A 'nodejslogger' module can be used for simple logging. It has three levels of logging (INFO, ERROR, DEBUG)
var logger = require('nodejslogger')
logger.init({"file":"output-file", "mode":"DIE"})
D : Debug, I : Info, E : Error
logger.debug("Debug logs")
logger.info("Info logs")
logger.error("Error logs")
The module can be accessed at : https://www.npmjs.com/package/nodejslogger
JSLint sometimes gives you unrealistic reasons to modify stuff. ===
has exactly the same performance as ==
if the types are already the same.
It is faster only when the types are not the same, in which case it does not try to convert types but directly returns a false.
So, IMHO, JSLint maybe used to write new code, but useless over-optimizing should be avoided at all costs.
Meaning, there is no reason to change ==
to ===
in a check like if (a == 'test')
when you know it for a fact that a can only be a String.
Modifying a lot of code that way wastes developers' and reviewers' time and achieves nothing.
Even if it is really discouraged to use merge cells in Excel (use Center Across Selection
for instance if needed), the cell that "contains" the value is the one on the top left (at least, that's a way to express it).
Hence, you can get the value of merged cells in range B4:B11
in several ways:
Range("B4").Value
Range("B4:B11").Cells(1).Value
Range("B4:B11").Cells(1,1).Value
You can also note that all the other cells have no value in them. While debugging, you can see that the value is empty
.
Also note that Range("B4:B11").Value
won't work (raises an execution error number 13 if you try to Debug.Print
it) because it returns an array.
Switch to some other branch and delete Test_Branch
, as follows:
$ git checkout master
$ git branch -d Test_Branch
If above command gives you error - The branch 'Test_Branch' is not fully merged. If you are sure you want to delete it
and still you want to delete it, then you can force delete it using -D
instead of -d
, as:
$ git branch -D Test_Branch
To delete Test_Branch
from remote as well, execute:
git push origin --delete Test_Branch
It says that the file C:\wamp\www\mysite\php\includes\dbconn.inc
doesn't exist, so the error is, you're missing the file.
Where the data returned is a string; you could cast to a different data type:
(from DataRow row in dataTable.Rows select row["columnName"].ToString()).ToList();
to clarify a bit on dragon's answer (since it took me a while to figure out what to do with Handler.Callback
):
Handler
can be used to execute callbacks in the current or another thread, by passing it Message
s. the Message
holds data to be used from the callback. a Handler.Callback
can be passed to the constructor of Handler
in order to avoid extending Handler directly. thus, to execute some code via callback from the current thread:
Message message = new Message();
<set data to be passed to callback - eg message.obj, message.arg1 etc - here>
Callback callback = new Callback() {
public boolean handleMessage(Message msg) {
<code to be executed during callback>
}
};
Handler handler = new Handler(callback);
handler.sendMessage(message);
EDIT: just realized there's a better way to get the same result (minus control of exactly when to execute the callback):
post(new Runnable() {
@Override
public void run() {
<code to be executed during callback>
}
});
import os
print os.getcwd() # Prints the current working directory
To set the working directory:
os.chdir('c:\\Users\\uname\\desktop\\python') # Provide the new path here
You can use google gson library to convert json object.
https://code.google.com/p/google-gson/?
Other librarys like Jackson are also available.
This won't convert it to a map. But you can do all things which you want.
Use this query to create the new table with the values from existing table
CREATE TABLE New_Table_name AS SELECT * FROM Existing_table_Name;
Now you can get all the values from existing table into newly created table.
"outDir"
Should be different from
"rootDir"
example
"outDir": "./dist",
"rootDir": "./src",

My problem was fideloper proxy
version.
when i upgraded laravel 5.5 to 5.8 this happened
just sharing if anybody get help
change you composer json fideloper version:
"fideloper/proxy": "^4.0",
After that you need to run update composer that's it.
composer update
there is configuration in the following way:
Preferences -> keys -> Navigation shortcuts
the 3rd option: shortcut to choose a split pane is "no shortcut" by default, we can choose one
cheers
Sometimes, XCode does not forget the line which had an "Editor Placeholder" even if you have replaced it with a value. Cut the portion of the code where XCode is complaining and paste the code back to the same place to make the error message go away. This worked for me.

The last-child
selector is used to select the last child element of a parent. It cannot be used to select the last child element with a specific class under a given parent element.
The other part of the compound selector (which is attached before the :last-child
) specifies extra conditions which the last child element must satisfy in-order for it to be selected. In the below snippet, you would see how the selected elements differ depending on the rest of the compound selector.
.parent :last-child{ /* this will select all elements which are last child of .parent */_x000D_
font-weight: bold;_x000D_
}_x000D_

To answer your question, the below would style the last child li
element with background color as red.
li:last-child{
background-color: red;
}
But the following selector would not work for your markup because the last-child
does not have the class='complete'
even though it is an li
.
li.complete:last-child{
background-color: green;
}
It would have worked if (and only if) the last li
in your markup also had class='complete'
.
To address your query in the comments:
@Harry I find it rather odd that: .complete:last-of-type does not work, yet .complete:first-of-type does work, regardless of it's position it's parents element. Thanks for your help.
The selector .complete:first-of-type
works in the fiddle because it (that is, the element with class='complete'
) is still the first element of type li
within the parent. Try to add <li>0</li>
as the first element under the ul
and you will find that first-of-type
also flops. This is because the first-of-type
and last-of-type
selectors select the first/last element of each type under the parent.
Refer to the answer posted by BoltClock, in this thread for more details about how the selector works. That is as comprehensive as it gets :)
Nothing really worked for me, until I updated the SDK version I was using. I started with 5.0. Not even 5.4.0 would not work either. When I updated to 5.6.2, it worked flawlessly, despite there being nothing in the changelogs that was relevant!
I developed a jQuery plugin that allows you to call any core PHP function or even user defined PHP functions as methods of the plugin: jquery.php
After including jquery and jquery.php in the head of our document and placing request_handler.php on our server we would start using the plugin in the manner described below.
For ease of use reference the function in a simple manner:
var P = $.fn.php;
Then initialize the plugin:
P('init',
{
// The path to our function request handler is absolutely required
'path': 'http://www.YourDomain.com/jqueryphp/request_handler.php',
// Synchronous requests are required for method chaining functionality
'async': false,
// List any user defined functions in the manner prescribed here
// There must be user defined functions with these same names in your PHP
'userFunctions': {
languageFunctions: 'someFunc1 someFunc2'
}
});
And now some usage scenarios:
// Suspend callback mode so we don't work with the DOM
P.callback(false);
// Both .end() and .data return data to variables
var strLenA = P.strlen('some string').end();
var strLenB = P.strlen('another string').end();
var totalStrLen = strLenA + strLenB;
console.log( totalStrLen ); // 25
// .data Returns data in an array
var data1 = P.crypt("Some Crypt String").data();
console.log( data1 ); // ["$1$Tk1b01rk$shTKSqDslatUSRV3WdlnI/"]
Demonstrating PHP function chaining:
var data1 = P.strtoupper("u,p,p,e,r,c,a,s,e").strstr([], "C,A,S,E").explode(",", [], 2).data();
var data2 = P.strtoupper("u,p,p,e,r,c,a,s,e").strstr([], "C,A,S,E").explode(",", [], 2).end();
console.log( data1, data2 );
Demonstrating sending a JSON block of PHP pseudo-code:
var data1 =
P.block({
$str: "Let's use PHP's file_get_contents()!",
$opts:
[
{
http: {
method: "GET",
header: "Accept-language: en\r\n" +
"Cookie: foo=bar\r\n"
}
}
],
$context:
{
stream_context_create: ['$opts']
},
$contents:
{
file_get_contents: ['http://www.github.com/', false, '$context']
},
$html:
{
htmlentities: ['$contents']
}
}).data();
console.log( data1 );
The backend configuration provides a whitelist so you can restrict which functions can be called. There are a few other patterns for working with PHP described by the plugin as well.
When you have a conflict during rebase you have three options:
You can run git rebase --abort
to completely undo the rebase. Git will return you to your branch's state as it was before git rebase was called.
You can run git rebase --skip
to completely skip the commit. That means
that none of the changes introduced by the problematic commit will be included. It is very rare that you would choose this option.
You can fix the conflict as iltempo said. When you're finished, you'll need to call git rebase --continue
. My mergetool is kdiff3 but there are many more which you can use to solve conflicts. You only need to set your merge tool in git's settings so it can be invoked when you call git mergetool
https://git-scm.com/docs/git-mergetool
If none of the above works for you, then go for a walk and try again :)
PHP’s mysql_real_escape_string
function is only a wrapper for MySQL’s mysql_real_escape_string
function. It basically prepares the input string to be safely used in a MySQL string declaration by escaping certain characters so that they can’t be misinterpreted as a string delimiter or an escape sequence delimiter and thereby allow certain injection attacks.
The real in mysql_real_escape_string
in opposite to mysql_escape_string
is due to the fact that it also takes the current character encoding into account as the risky characters are not encoded equally in the different character encodings. But you need to specify the character encoding change properly in order to get mysql_real_escape_string
work properly.
I wanted a solution for this similar to apt-get --print-uris
, but unfortunately apt-cyg doesn't do this. The following is a solution that allowed me to download only the packages I needed, with their dependencies, and copy them to the target for installation. Here is a bash script that parses the output of apt-cyg
into a list of URIs:
#!/usr/bin/bash
package=$1
depends=$( \
apt-cyg depends $package \
| perl -ne 'while ($x = /> ([^>\s]+)/g) { print "$1\n"; }' \
| sort \
| uniq)
depends=$(echo -e "$depends\n$package")
for curpkg in $depends; do
if ! grep -q "^$curpkg " /etc/setup/installed.db; then
apt-cyg show $curpkg \
| perl -ne '
if ($x = /install: ([^\s]+)/) {
print "$1\n";
}
if (/\[prev\]/) {
exit;
}'
fi
done
The above will print out the paths of the packages that need downloading, relative to the cygwin mirror root, omitting any packages that are already installed. To download them, I wrote the output to a file cygwin-packages-list
and then used wget:
mirror=http://cygwin.mirror.constant.com/
uris=$(for line in $(cat cygwin-packages-list); do echo "$mirror$line"; done)
wget -x $uris
The installer can then be used to install from a local cache directory. Note that for this to work I needed to copy setup.ini
from a previous cygwin package cache to the directory with the downloaded files (otherwise the installer doesn't know what's what).
The Classloader API doesn't have an "enumerate" method, because class loading is an "on-demand" activity -- you usually have thousands of classes in your classpath, only a fraction of which will ever be needed (the rt.jar alone is 48MB nowadays!).
So, even if you could enumerate all classes, this would be very time- and memory-consuming.
The simple approach is to list the concerned classes in a setup file (xml or whatever suits your fancy); if you want to do this automatically, restrict yourself to one JAR or one class directory.
You can use VBSedit software to convert your VBS code to .exe file. You can download free version from Internet and installtion vbsedit applilcation on your system and convert the files to exe format.
Vbsedit is a good application for VBscripter's
You simply want the File.GetLastWriteTime
static method.
Example:
var lastModified = System.IO.File.GetLastWriteTime("C:\foo.bar");
Console.WriteLine(lastModified.ToString("dd/MM/yy HH:mm:ss"));
Note however that in the rare case the last-modified time is not updated by the system when writing to the file (this can happen intentionally as an optimisation for high-frequency writing, e.g. logging, or as a bug), then this approach will fail, and you will instead need to subscribe to file write notifications from the system, constantly listening.

Also for openCV in python you can do:
img = cv2.imread('myImage.jpg')
height, width, channels = img.shape
I think we can modify the UsedRange
code from @Readify's answer above to get the last used column even if the starting columns are blank or not.
So this lColumn = ws.UsedRange.Columns.Count
modified to
this lColumn = ws.UsedRange.Column + ws.UsedRange.Columns.Count - 1
will give reliable results always
?Sheet1.UsedRange.Column + Sheet1.UsedRange.Columns.Count - 1

Use the @RequestParam to pass a parameter to the controller handler method.
In the jsp your form should have an input field with name = "id"
like the following:
<input type="text" name="id" />
<input type="submit" />
Then in your controller, your handler method should be like the following:
@RequestMapping("listNotes")
public String listNotes(@RequestParam("id") int id) {
Person person = personService.getCurrentlyAuthenticatedUser();
model.addAttribute("person", new Person());
model.addAttribute("listPersons", this.personService.listPersons());
model.addAttribute("listNotes", this.notesService.listNotesBySectionId(id, person));
return "note";
}
Please also refer to these answers and tutorial:
Since no other answer has cited the Java language standard, I have decided to write an answer of my own:
In Java, local variables are not, by default, initialized with a certain value (unlike, for example, the field of classes). From the language specification one (§4.12.5) can read the following:
A local variable (§14.4, §14.14) must be explicitly given a value before it is used, by either initialization (§14.4) or assignment (§15.26), in a way that can be verified using the rules for definite assignment (§16 (Definite Assignment)).
Therefore, since the variables a
and b
are not initialized :
for (int l= 0; l<x.length; l++)
{
if (x[l] == 0)
a++ ;
else if (x[l] == 1)
b++ ;
}
the operations a++;
and b++;
could not produce any meaningful results, anyway. So it is logical for the compiler to notify you about it:
Rand.java:72: variable a might not have been initialized
a++ ;
^
Rand.java:74: variable b might not have been initialized
b++ ;
^
However, one needs to understand that the fact that a++;
and b++;
could not produce any meaningful results has nothing to do with the reason why the compiler displays an error. But rather because it is explicitly set on the Java language specification that
A local variable (§14.4, §14.14) must be explicitly given a value (...)
To showcase the aforementioned point, let us change a bit your code to:
public static Rand searchCount (int[] x)
{
if(x == null || x.length == 0)
return null;
int a ;
int b ;
...
for (int l= 0; l<x.length; l++)
{
if(l == 0)
a = l;
if(l == 1)
b = l;
}
...
}
So even though the code above can be formally proven to be valid (i.e., the variables a
and b
will be always assigned with the value 0
and 1
, respectively) it is not the compiler job to try to analyze your application's logic, and neither does the rules of local variable initialization rely on that. The compiler checks if the variables a
and b
are initialized according to the local variable initialization rules, and reacts accordingly (e.g., displaying a compilation error).
If you want to use them like that, define the function with the variable names as normal:
def my_function(school, standard, city, name):
schoolName = school
cityName = city
standardName = standard
studentName = name
Now you can use **
when you call the function:
data = {'school':'DAV', 'standard': '7', 'name': 'abc', 'city': 'delhi'}
my_function(**data)
and it will work as you want.
P.S. Don't use reserved words such as class
.(e.g., use klass
instead)
Based on the accepted answer by delnan.
What if one of your wanted keys aren't in the old_dict? The delnan solution will throw a KeyError exception that you can catch. If that's not what you need maybe you want to:
only include keys that excists both in the old_dict and your set of wanted_keys.
old_dict = {'name':"Foobar", 'baz':42}
wanted_keys = ['name', 'age']
new_dict = {k: old_dict[k] for k in set(wanted_keys) & set(old_dict.keys())}
>>> new_dict
{'name': 'Foobar'}
have a default value for keys that's not set in old_dict.
default = None
new_dict = {k: old_dict[k] if k in old_dict else default for k in wanted_keys}
>>> new_dict
{'age': None, 'name': 'Foobar'}
I had the same issues. I have followed @ThomasReggi and @CoolAJ86 solution and worked well but I'm not satisfied with the solution.
Because "UNABLE_TO_VERIFY_LEAF_SIGNATURE" issue is happened due to certification configuration level.
I accept @thirdender solution but its partial solution.As per the nginx official website, they clearly mentioned certificate should be combination of The server certificate and chained certificates.
Similar to yebmouxing I could not the
xhr.getResponseHeader('Set-Cookie');
method to work. It would only return null even if I had set HTTPOnly to false on my server.
I too wrote a simple js helper function to grab the cookies from the document. This function is very basic and only works if you know the additional info (lifespan, domain, path, etc. etc.) to add yourself:
function getCookie(cookieName){
var cookieArray = document.cookie.split(';');
for(var i=0; i<cookieArray.length; i++){
var cookie = cookieArray[i];
while (cookie.charAt(0)==' '){
cookie = cookie.substring(1);
}
cookieHalves = cookie.split('=');
if(cookieHalves[0]== cookieName){
return cookieHalves[1];
}
}
return "";
}
I could do this in a JUnit Test Setup.

Doesn't SELECT LEN(column_name)
work?
Figured it out.
Put a new column to the left of column1 and copy+paste the following formula
=B2=B3
=B3=B4
=B4=B5
... all the way to the bottom (assume column B here is column1 in the original question).
This formula evaluates whether or not the next row is a new value in column1. Deopending on the result, you will have TRUE or FALSE. Copy and Paste these results as values and then swap "FALSE" for nil and "TRUE" for 0.5
Then add that column full of only 0.5's to the column1 which will yield the following table:
newcolumn0 | column1 ("B") | column2 | column3
-----------------------------------------------------
| 1 | small | blue
| 1 | small | orange
1.5 | 1 | small | yellow
| 2 | med | yellow
2.5 | 2 | med | blue
3.5 | 3 | large | green
| 4 | large | green
4.5 | 4 | small | pink
Lastly, copy and paste the values from newcolumn0 right below the values in column1 and then sort the table by column1 and you should have a blank row in between each distinct whole number in column1, with the table something like this:
newcolumn0 | column1 ("B") | column2 | column3
---------------------------------------------------------------
| 1 | small | blue
| 1 | small | orange
1.5 | 1.5 | |

and copy+paste this formula for the rest of column 2I'm guessing that you're trying to find if a certain value exists inside the array, and if that's the case, you can use Array#include?(value):
a = [1,2,3,4,5]
a.include?(3) # => true
a.include?(9) # => false
If you mean something else, check the Ruby Array API
You can use:
select VARCHAR_FORMAT(creationdate, 'MM/DD/YYYY') from table name
I eventually figured out an easy way to do it:

The problem is probably that the JVM client doesn't trust the repo.maven.apache.org certificate. As suggested, you can try and access https://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-clean-plugin/2.5/maven-clean-plugin-2.5.pom in your browser.
If that works - this is probably the case. You will have to explicitly tell the JMV to trust maven certificate. You can refer to the answer here "PKIX path building failed" and "unable to find valid certification path to requested target"
for me on Mac OS, the certificate file is located at /Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home/jre/lib/security and the certificate you need is the one presented to your browser when you enter the URL mentioned above
Few days ago, a fell into the same problem & had to sit with the math book. I solved the problem by combining and simplifying some basic formulas.
Lets consider this figure-
We want to know ?, so we need to find out a and ß first. Now, for any straight line-
y = m * x + c
Let- A = (ax, ay), B = (bx, by), and O = (ox, oy). So for the line OA-
oy = m1 * ox + c ? c = oy - m1 * ox ...(eqn-1)
ay = m1 * ax + c ? ay = m1 * ax + oy - m1 * ox [from eqn-1]
? ay = m1 * ax + oy - m1 * ox
? m1 = (ay - oy) / (ax - ox)
? tan a = (ay - oy) / (ax - ox) [m = slope = tan ?] ...(eqn-2)
In the same way, for line OB-
tan ß = (by - oy) / (bx - ox) ...(eqn-3)
Now, we need ? = ß - a
. In trigonometry we have a formula-
tan (ß-a) = (tan ß + tan a) / (1 - tan ß * tan a) ...(eqn-4)
After replacing the value of tan a
(from eqn-2) and tan b
(from eqn-3) in eqn-4, and applying simplification we get-
tan (ß-a) = ( (ax-ox)*(by-oy)+(ay-oy)*(bx-ox) ) / ( (ax-ox)*(bx-ox)-(ay-oy)*(by-oy) )
So,
? = ß-a = tan^(-1) ( ((ax-ox)*(by-oy)+(ay-oy)*(bx-ox)) / ((ax-ox)*(bx-ox)-(ay-oy)*(by-oy)) )
That is it!
Now, take following figure-
This C# or, Java method calculates the angle (?)-
private double calculateAngle(double P1X, double P1Y, double P2X, double P2Y,
double P3X, double P3Y){
double numerator = P2Y*(P1X-P3X) + P1Y*(P3X-P2X) + P3Y*(P2X-P1X);
double denominator = (P2X-P1X)*(P1X-P3X) + (P2Y-P1Y)*(P1Y-P3Y);
double ratio = numerator/denominator;
double angleRad = Math.Atan(ratio);
double angleDeg = (angleRad*180)/Math.PI;
if(angleDeg<0){
angleDeg = 180+angleDeg;
}
return angleDeg;
}
Let me post a solution here for C++03 that I consider the cleanest possible.*
#define DECLARE_LAMBDA(NAME, RETURN_TYPE, FUNCTION) \
struct { RETURN_TYPE operator () FUNCTION } NAME;
...
int main(){
DECLARE_LAMBDA(demoLambda, void, (){ cout<<"I'm a lambda!"<<endl; });
demoLambda();
DECLARE_LAMBDA(plus, int, (int i, int j){
return i+j;
});
cout << "plus(1,2)=" << plus(1,2) << endl;
return 0;
}
(*) in the C++ world using macros is never considered clean.
For future Googlers i've a different approach to check if it's last element. It's similar to last lines in OP question.
This directly compares elements rather than just checking index numbers.
$yourset.each(function() {
var $this = $(this);
if($this[0] === $yourset.last()[0]) {
//$this is the last one
}
});
SELECT * FROM

This was discussed in the String methods... finally thread in the Python-Dev achive, and was accepted by Guido. This thread began in Jun 1999, and str.join
was included in Python 1.6 which was released in Sep 2000 (and supported Unicode). Python 2.0 (supported str
methods including join
) was released in Oct 2000.
str.join(seq)
seq.join(str)
seq.reduce(str)
join
as a built-in functionlist
s, tuple
s, but all sequences/iterables.seq.reduce(str)
is difficult for new-comers.seq.join(str)
introduces unexpected dependency from sequences to str/unicode.join()
as a built-in function would support only specific data types. So using a built in namespace is not good. If join()
supports many datatypes, creating optimized implementation would be difficult, if implemented using the __add__
method then it's O(n²).sep
) should not be omitted. Explicit is better than implicit.There are no other reasons offered in this thread.
Here are some additional thoughts (my own, and my friend's):
Guido's decision is recorded in a historical mail, deciding on str.join(seq)
:
Funny, but it does seem right! Barry, go for it...

foreach (string file in Directory.EnumerateFiles(folderPath, "*.xml"))
{
string contents = File.ReadAllText(file);
}
Note the above uses a .NET 4.0 feature; in previous versions replace EnumerateFiles

). Also, replace File.ReadAllText
with your preferred way of reading xml files - perhaps XDocument

or an XmlReader
.
Code below (taken from my blog article - http://todayguesswhat.blogspot.com/2021/01/manually-verifying-rsa-sha-signature-in.html ) is hopefully helpful in understanding what is present in a standard SHA with RSA signature. This should work in standard Oracle JDK and does not require Bouncy Castle libraries. It is using the sun.security classes to process the decrypted signature contents - you could just as easily manually parse.
In the example below, the message digest algorithm is SHA-512 which produces a 64 byte (512-bit) checksum.
SHA-1 would be pretty similar - but producing a 20-byte (160-bit) checksum.

Taking above sample bytes ...
0x30 means A SEQUENCE - which contains an ordered field of one or more types.
It is encoded into a TLV triplet that begins with a Tag byte of 0x30.
DER uses T,L,V (tag bytes, length bytes, value bytes) format
0x51 is the length = 81 decimal (13 bytes)
the 0x30 (48 decimal) that follows begins a second sequence

where || is concatenation and H is the hash value.
0x0D is the length = 13 decimal (13 bytes)
0x06 means an OBJECT_ID tag
0x09 means the object id is 9 bytes ...
https://docs.microsoft.com/en-au/windows/win32/seccertenroll/about-object-identifier?redirectedfrom=MSDN
taking 2.16.840.1.101.3.4.2.3 (object id for SHA512 Hash Algorithm)
The first two nodes of the OID are encoded onto a single byte.
The first node is multiplied by the decimal 40 and the result is added to the value of the second node
2 * 40 + 16 = 96 decimal = 60 hex
Node values less than or equal to 127 are encoded on one byte.
1 101 3 4 2 3 corresponds to in hex 01 65 03 04 02 03
Node values greater than or equal to 128 are encoded on multiple bytes.
Bit 7 of the leftmost byte is set to one. Bits 0 through 6 of each byte contains the encoded value.

Here's another solution using a package solely dedicated to working with dates and times in R:
library(tidyverse)
library(lubridate)

#> ID Date
#> <int> <chr>
#> 1 1 2004-02-06
#> 2 2 2006-03-14
#> 3 3 2007-07-16
df %>%
mutate(
Date = ymd(Date),
Month_Yr = format_ISO8601(Date, precision = "ym")
)
#> # A tibble: 3 x 3
#> ID Date Month_Yr
#> <int> <date> <chr>

Achintya Jha has the right idea here. Instead of thinking about how to remove duplicates, you remove the ability for duplicates to be created in the first place.
If you want to stick with an array of ints and want to randomize their order (manually, which is quite simple) follow these steps.
Your code could be modified to look like this:
import java.util.Random;
public class Sort
{
// use a constant rather than having the "magic number" 10000 scattered about
public static final int N = 10000;
public static void main(String[] args)
{
//array to store N random integers (0 - N-1)
int[] nums = new int[N];
// initialize each value at index i to the value i
for (int i = 0; i < nums.length; ++i)
{
nums[i] = i;
}
Random randomGenerator = new Random();
int randomIndex; // the randomly selected index each time through the loop
int randomValue; // the value at nums[randomIndex] each time through the loop
// randomize order of values
for(int i = 0; i < nums.length; ++i)
{
// select a random index
randomIndex = randomGenerator.nextInt(nums.length);
// swap values
randomValue = nums[randomIndex];
nums[randomIndex] = nums[i];
nums[i] = randomValue;
}
}
}
And if I were you I would likely break each of these blocks into separate, smaller methods rather than having one large main method.
Hope this helps.
You can prefix the size requirement with -
to left-justify:
sys.stdout.write("%-6s %-50s %-25s\n" % (code, name, industry))
The simplest way to do that is by opening the certificate store you want and then using X509Certificate2UI
.
var store = new X509Store(StoreName.My, StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadOnly);
var selectedCertificate = X509Certificate2UI.SelectFromCollection(
store.Certificates,
"Title",
"MSG",
X509SelectionFlag.SingleSelection);
More information in X509Certificate2UI
on MSDN.
I think the most efficient way is to preallocate and then emplace elements:
template <typename T>
std::vector<T> VectorFromSet(const std::set<T>& from)
{
std::vector<T> to;
to.reserve(from.size());
for (auto const& value : from)
to.emplace_back(value);
return to;
}
That way we will only invoke copy constructor for every element as opposed to calling default constructor first and then copy assignment operator for other solutions listed above. More clarifications below.
back_inserter may be used but it will invoke push_back() on the vector (https://en.cppreference.com/w/cpp/iterator/back_insert_iterator). emplace_back() is more efficient because it avoids creating a temporary when using push_back(). It is not a problem with trivially constructed types but will be a performance implication for non-trivially constructed types (e.g. std::string).
We need to avoid constructing a vector with the size argument which causes all elements default constructed (for nothing). Like with solution using std::copy(), for instance.
And, finally, vector::assign() method or the constructor taking the iterator range are not good options because they will invoke std::distance() (to know number of elements) on set iterators. This will cause unwanted additional iteration through the all set elements because the set is Binary Search Tree data structure and it does not implement random access iterators.
Hope that helps.
I know this is well answered, but if you're interested, I wrote a library that makes executing commands much easier.
Check it out here: https://github.com/twitchax/Sheller.
<?php
if (isset($_POST['str'])){
function printme($str){
echo $str;
}
printme("{$_POST['str']}");

<input type="text" name="str" /> <input type="submit" value="Submit"/>
</form>
Okay. I finally found what actually works to answer the question that seems to be asked;
"When needing many modules and forms, how can I declare a variable to be public to all of them such that they each reference the same variable?"
Amazingly to me, I spent considerable time searching the web for that seemingly simple question, finding nothing but vagueness that left me still getting errors.
But thanks to Cody Gray's link to an example, I was able to discern a proper answer;
Situation; You have multiple Modules and/or Forms and want to reference a particular variable from each or all.
"A" way that works; On one module place the following code (wherein "DefineGlobals" is an arbitrarily chosen name);
Public Module DefineGlobals
Public Parts As Integer 'Assembled-particle count
Public FirstPrtAff As Long 'Addr into Link List
End Module
And then in each Module/Form in need of addressing that variable "Parts", place the following code (as an example of the "InitForm2" form);
Public Class InitForm2
Private Sub InitForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Parts = Parts + 3
End Sub
End Class
And perhaps another Form; Public Class FormX
Sub CreateAff()
Parts = 1000
End Sub
End Class
That type of coding seems to have worked on my VB2008 Express and seems to be all needed at the moment (void of any unknown files being loaded in the background) even though I have found no end to the "Oh btw..." surprise details. And I'm certain a greater degree of standardization would be preferred, but the first task is simply to get something working at all, with or without standards.
Nothing beats exact and well worded, explicit examples.
Thanks again, Cody
To support IE11 with auto-placement, I converted grid
to table

The result is the same, see how you can do it here https://jsfiddle.net/hp95z6v1/3/
This appears to be a bug in the SelectExtensions class as it will only check the ViewData rather than the model for the selected item. So the trick is to copy the selected item from the model into the ViewData collection under the name of the property.
This is taken from the answer I gave on the MVC forums, I also have a more complete answer in a blog post that uses Kazi's DropDownList attribute...
Given a model
public class ArticleType
{
public Guid Id { get; set; }
public string Description { get; set; }
}
public class Article
{
public Guid Id { get; set; }
public string Name { get; set; }
public ArticleType { get; set; }
}
and a basic view model of
public class ArticleModel
{
public Guid Id { get; set; }
public string Name { get; set; }
[UIHint("DropDownList")]
public Guid ArticleType { get; set; }
}
Then we write a DropDownList editor template as follows..
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>
<script runat="server">
IEnumerable<SelectListItem> GetSelectList()
{
var metaData = ViewData.ModelMetadata;
if (metaData == null)
{
return null;
}
var selected = Model is SelectListItem ? ((SelectListItem) Model).Value : Model.ToString();
ViewData[metaData.PropertyName] = selected;
var key = metaData.PropertyName + "List";
return (IEnumerable<SelectListItem>)ViewData[key];
}
</script>
<%= Html.DropDownList(null, GetSelectList()) %>
This will also work if you change ArticleType in the view model to a SelectListItem, though you do have to implement a type converter as per Kazi's blog and register it to force the binder to treat this as a simple type.
In your controller we then have...
public ArticleController
{
...
public ActionResult Edit(int id)
{
var entity = repository.FindOne<Article>(id);
var model = builder.Convert<ArticleModel>(entity);
var types = repository.FindAll<ArticleTypes>();
ViewData["ArticleTypeList"] = builder.Convert<SelectListItem>(types);
return VIew(model);
}
...
}
SELECT sc.name +'.'+ ta.name TableName
,SUM(pa.rows) RowCnt
FROM sys.tables ta
INNER JOIN sys.partitions pa
ON pa.OBJECT_ID = ta.OBJECT_ID
INNER JOIN sys.schemas sc
ON ta.schema_id = sc.schema_id
WHERE ta.is_ms_shipped = 0 AND pa.index_id IN (1,0)
GROUP BY sc.name,ta.name
ORDER BY SUM(pa.rows) DESC
See this:
This is still the top post when searching, but it's no longer valid. Best answer is here, but the TLDR is
<c-b>:resize-window -A
Talking about functional PHP, I have this more generic answer:
array_map(function($arr){
$ret = $arr;
$ret['value'] = $ret['url'];
unset($ret['url']);
return $ret;
}, $tag);
}
You most likely mean "yyyy-MM-dd" small latter 'm' would imply minutes section.
You should do two things
add spring.jackson.serialization.write-dates-as-timestamps:false
in your application.properties
this will disable converting dates to timestamps and instead use a ISO-8601 compliant format
You can than customize the format by annotating the getter method of you dateOfBirth
property with @JsonFormat(pattern="yyyy-MM-dd")
rebellion's answer above won't actually work, because to CSS, 'background-position' is actually shorthand for 'background-position-x' and 'background-position-y' so the correct version of his code would be:
$(document).ready(function(){
$('#submenu li').hover(function(){
$('#carousel').css('background-position-x', newValueX);
$('#carousel').css('background-position-y', newValue);
}, function(){
$('#carousel').css('background-position-x', oldValueX);
$('#carousel').css('background-position-y', oldValueY);
});
});
It took about 4 hours of banging my head against it to come to that aggravating realization.
As stated in MSDN (eg. https://msdn.microsoft.com/en-us/library/system.diagnostics.eventlog(v=vs.110).aspx ), checking an non existing source and creating a source requires admin privilege.
It is however possible to use the source "Application" without. In my test under Windows 2012 Server r2, I however get the following log entry using "Application" source:
The description for Event ID xxxx from source Application cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: {my event entry message} the message resource is present but the message is not found in the string/message table
I defined the following method to create the source:
private string CreateEventSource(string currentAppName)
{
string eventSource = currentAppName;
bool sourceExists;
try
{
// searching the source throws a security exception ONLY if not exists!
sourceExists = EventLog.SourceExists(eventSource);
if (!sourceExists)
{ // no exception until yet means the user as admin privilege
EventLog.CreateEventSource(eventSource, "Application");
}
}
catch (SecurityException)
{
eventSource = "Application";
}
return eventSource;
}
I am calling it with currentAppName = AppDomain.CurrentDomain.FriendlyName
It might be possible to use the EventLogPermission class instead of this try/catch but not sure we can avoid the catch.
It is also possible to create the source externally, e.g in elevated Powershell:
New-EventLog -LogName Application -Source MyApp
Then, using 'MyApp' in the method above will NOT generate exception and the EventLog can be created with that source.

The issue of adding tooltips to any HTML-Output (not only FontAwesome) is an entire book on its own. ;-)
The default way would be to use the title-attribute:
<div id="welcomeText" title="So nice to see you!">
<p>Welcome Harriet</p>
</div>
or
<i class="fa fa-cog" title="Do you like my fa-coq icon?"></i>
But since most people (including me) do not like the standard-tooltips, there are MANY tools out there which will "beautify" them and offer all sort of enhancements. My personal favourites are jBox and qtip2.
HTTP_CLIENT_IP is the most reliable way of getting the user's IP address. Next is HTTP_X_FORWARDED_FOR, followed by REMOTE_ADDR. Check all three, in that order, assuming that the first one that is set (isset($_SERVER['HTTP_CLIENT_IP'])
returns true if that variable is set) is correct. You can independently check if the user is using a proxy using various methods. Check this out.
Lets suppose there is a table with following describe command for table (hello)- name char(100), id integer, count integer, city char(100).
we have following basic commands for MySQL -
select * from hello;
select name, city from hello;
etc
select name from hello where id = 8;
select id from hello where name = 'GAURAV';
now lets see multiple where condition -
select name from hello where id = 3 or id = 4 or id = 8 or id = 22;
select name from hello where id =3 and count = 3 city = 'Delhi';
This is how we can use multiple where commands in MySQL.
Try passing multiple values via url:
/ReportServer?%2fService+Specific+Reports%2fFilings%2fDrillDown%2f&StartDate=01/01/2010&EndDate=01/05/2010&statuses=1&statuses=2&rs%3AFormat=PDF
This should work.
$cmd
would just replace the variable with it's value to be executed on command line.
eval "$cmd"
does variable expansion & command substitution before executing the resulting value on command line
The 2nd method is helpful when you wanna run commands that aren't flexible eg.
for i in {$a..$b}
format loop won't work because it doesn't allow variables.
In this case, a pipe to bash or eval is a workaround.

You can use git log to display the diffs while searching:
git log -p -- path/to/file
With EL 2 you can do the following:

Indeed, the docker registry as of today (sha 2e2f252f3c88679f1207d87d57c07af6819a1a17e22573bcef32804122d2f305
) does not handle paths containing upper-case characters. This is obviously a poor design choice, probably due to wanting to maintain compatible with certain operating systems that do not distinguish case at the file level (ie, windows).
If one authenticates for a scope and tries to fetch a non-existing repository with all lowercase, the output is
(auth step not shown)
curl -s -H "Authorization: Bearer $TOKEN" -X GET https://$LOCALREGISTRY/v2/test/someproject/tags/list
{"errors":[{"code":"UNAUTHORIZED","message":"authentication required","detail":[{"Type":"repository","Class":"","Name":"test/someproject","Action":"pull"}]}]}
However, if one tries to do this with an uppercase component, only 404 is returned:
(authorization step done but not shown here)
$ curl -s -H "Authorization: Bearer $TOKEN" -X GET https://docker.uibk.ac.at:443/v2/test/Someproject/tags/list
404 page not found
You need to subscribe to the observable and pass a callback that processes emitted values
this.myService.getConfig().subscribe(val => console.log(val));
It's a syntax for array references - you need to use (&array)
to clarify to the compiler that you want a reference to an array, rather than the (invalid) array of references int & array[100];
.
EDIT: Some clarification.
void foo(int * x);
void foo(int x[100]);
void foo(int x[]);
These three are different ways of declaring the same function. They're all treated as taking an int *
parameter, you can pass any size array to them.
void foo(int (&x)[100]);
This only accepts arrays of 100 integers. You can safely use sizeof
on x
void foo(int & x[100]); // error
This is parsed as an "array of references" - which isn't legal.
There are two primary ways that pandas makes selections from a DataFrame.
The documentation uses the term position for referring to integer location. I do not like this terminology as I feel it is confusing. Integer location is more descriptive and is exactly what .iloc
stands for. The key word here is INTEGER - you must use integers when selecting by integer location.
Before showing the summary let's all make sure that ...
There are three primary indexers for pandas. We have the indexing operator itself (the brackets []
), .loc
, and .iloc
. Let's summarize them:
[]
- Primarily selects subsets of columns, but can select rows as well. Cannot simultaneously select rows and columns..loc
- selects subsets of rows and columns by label only.iloc
- selects subsets of rows and columns by integer location onlyI almost never use .at
or .iat
as they add no additional functionality and with just a small performance increase. I would discourage their use unless you have a very time-sensitive application. Regardless, we have their summary:
.at
selects a single scalar value in the DataFrame by label only.iat
selects a single scalar value in the DataFrame by integer location onlyIn addition to selection by label and integer location, boolean selection also known as boolean indexing exists.
.loc
, .iloc
, boolean selection and .at
and .iat
are shown belowWe will first focus on the differences between .loc
and .iloc
. Before we talk about the differences, it is important to understand that DataFrames have labels that help identify each column and each row. Let's take a look at a sample DataFrame:
df = pd.DataFrame({'age':[30, 2, 12, 4, 32, 33, 69],
'color':['blue', 'green', 'red', 'white', 'gray', 'black', 'red'],
'food':['Steak', 'Lamb', 'Mango', 'Apple', 'Cheese', 'Melon', 'Beans'],
'height':[165, 70, 120, 80, 180, 172, 150],
'score':[4.6, 8.3, 9.0, 3.3, 1.8, 9.5, 2.2],
'state':['NY', 'TX', 'FL', 'AL', 'AK', 'TX', 'TX']
},
index=['Jane', 'Nick', 'Aaron', 'Penelope', 'Dean', 'Christina', 'Cornelia'])
All the words in bold are the labels. The labels, age
, color
, food
, height
, score
and state
are used for the columns. The other labels, Jane
, Nick
, Aaron
, Penelope
, Dean
, Christina
, Cornelia
are used as labels for the rows. Collectively, these row labels are known as the index.
The primary ways to select particular rows in a DataFrame are with the .loc
and .iloc
indexers. Each of these indexers can also be used to simultaneously select columns but it is easier to just focus on rows for now. Also, each of the indexers use a set of brackets that immediately follow their name to make their selections.
We will first talk about the .loc
indexer which only selects data by the index or column labels. In our sample DataFrame, we have provided meaningful names as values for the index. Many DataFrames will not have any meaningful names and will instead, default to just the integers from 0 to n-1, where n is the length(number of rows) of the DataFrame.
There are many different inputs you can use for .loc
three out of them are
Selecting a single row with .loc with a string
To select a single row of data, place the index label inside of the brackets following .loc
.
df.loc['Penelope']
This returns the row of data as a Series
age 4
color white
food Apple
height 80
score 3.3
state AL
Name: Penelope, dtype: object
Selecting multiple rows with .loc with a list of strings
df.loc[['Cornelia', 'Jane', 'Dean']]
This returns a DataFrame with the rows in the order specified in the list:
Selecting multiple rows with .loc with slice notation
Slice notation is defined by a start, stop and step values. When slicing by label, pandas includes the stop value in the return. The following slices from Aaron to Dean, inclusive. Its step size is not explicitly defined but defaulted to 1.
df.loc['Aaron':'Dean']
Complex slices can be taken in the same manner as Python lists.
Let's now turn to .iloc
. Every row and column of data in a DataFrame has an integer location that defines it. This is in addition to the label that is visually displayed in the output. The integer location is simply the number of rows/columns from the top/left beginning at 0.
There are many different inputs you can use for .iloc
three out of them are
Selecting a single row with .iloc with an integer
df.iloc[4]
This returns the 5th row (integer location 4) as a Series
age 32
color gray
food Cheese
height 180
score 1.8
state AK
Name: Dean, dtype: object
Selecting multiple rows with .iloc with a list of integers
df.iloc[[2, -2]]
This returns a DataFrame of the third and second to last rows:
Selecting multiple rows with .iloc with slice notation
df.iloc[:5:3]
One excellent ability of both .loc/.iloc
is their ability to select both rows and columns simultaneously. In the examples above, all the columns were returned from each selection. We can choose columns with the same types of inputs as we do for rows. We simply need to separate the row and column selection with a comma.
For example, we can select rows Jane, and Dean with just the columns height, score and state like this:
df.loc[['Jane', 'Dean'], 'height':]
This uses a list of labels for the rows and slice notation for the columns
We can naturally do similar operations with .iloc
using only integers.
df.iloc[[1,4], 2]
Nick Lamb
Dean Cheese
Name: food, dtype: object
.ix
was used to make selections simultaneously with labels and integer location which was useful but confusing and ambiguous at times and thankfully it has been deprecated. In the event that you need to make a selection with a mix of labels and integer locations, you will have to make both your selections labels or integer locations.
For instance, if we want to select rows Nick
and Cornelia
along with columns 2 and 4, we could use .loc
by converting the integers to labels with the following:
col_names = df.columns[[2, 4]]
df.loc[['Nick', 'Cornelia'], col_names]
Or alternatively, convert the index labels to integers with the get_loc
index method.
labels = ['Nick', 'Cornelia']
index_ints = [df.index.get_loc(label) for label in labels]
df.iloc[index_ints, [2, 4]]
The .loc indexer can also do boolean selection. For instance, if we are interested in finding all the rows where age is above 30 and return just the food
and score
columns we can do the following:
df.loc[df['age'] > 30, ['food', 'score']]
You can replicate this with .iloc
but you cannot pass it a boolean series. You must convert the boolean Series into a numpy array like this:
df.iloc[(df['age'] > 30).values, [2, 4]]
It is possible to use .loc/.iloc
for just column selection. You can select all the rows by using a colon like this:
df.loc[:, 'color':'score':2]
[]
, can slice can select rows and columns too but not simultaneously.Most people are familiar with the primary purpose of the DataFrame indexing operator, which is to select columns. A string selects a single column as a Series and a list of strings selects multiple columns as a DataFrame.
df['food']
Jane Steak
Nick Lamb
Aaron Mango
Penelope Apple
Dean Cheese
Christina Melon
Cornelia Beans
Name: food, dtype: object
Using a list selects multiple columns
df[['food', 'score']]
What people are less familiar with, is that, when slice notation is used, then selection happens by row labels or by integer location. This is very confusing and something that I almost never use but it does work.
df['Penelope':'Christina'] # slice rows by label
df[2:6:2] # slice rows by integer location
The explicitness of .loc/.iloc
for selecting rows is highly preferred. The indexing operator alone is unable to select rows and columns simultaneously.
df[3:5, 'color']
TypeError: unhashable type: 'slice'
.at
and .iat
Selection with .at
is nearly identical to .loc
but it only selects a single 'cell' in your DataFrame. We usually refer to this cell as a scalar value. To use .at
, pass it both a row and column label separated by a comma.
df.at['Christina', 'color']
'black'
Selection with .iat
is nearly identical to .iloc
but it only selects a single scalar value. You must pass it an integer for both the row and column locations
df.iat[2, 5]
'FL'
While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event
argument to the setMaster
function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):
function AdminController($scope) {
$scope.setMaster = function(obj, $event){
console.log($event.target);
}
}
this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.
The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event
argument) would be:
<div ng-controller="AdminController">
<ul class="list-holder">
<li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
<a ng-click="setMaster(section)">{{section.name}}</a>
</li>
</ul>
<hr>
{{selected | json}}
</div>
where methods in the controller would look like this:
$scope.setMaster = function(section) {
$scope.selected = section;
}
$scope.isSelected = function(section) {
return $scope.selected === section;
}
Here is the complete jsFiddle: http://jsfiddle.net/pkozlowski_opensource/WXJ3p/15/
Actually what you are searching is: Optional.map. Your code would then look like:
object.map(o -> "result" /* or your function */)
.orElseThrow(MyCustomException::new);
I would rather omit passing the Optional
if you can. In the end you gain nothing using an Optional
here. A slightly other variant:
public String getString(Object yourObject) {
if (Objects.isNull(yourObject)) { // or use requireNonNull instead if NullPointerException suffices
throw new MyCustomException();
}
String result = ...
// your string mapping function
return result;
}
If you already have the Optional
-object due to another call, I would still recommend you to use the map
-method, instead of isPresent
, etc. for the single reason, that I find it more readable (clearly a subjective decision ;-)).
I was running a job which ran a shell script in Jenkins on a Windows machine. The job was failing due to the error given below. I was able to fix the error thanks to clues in Andrejz's answer.

Solution :
1 - Install Cygwin and note the directory where it gets installed.
It was C:\cygwin64 in my case. The sh.exe which is needed to run shell scripts is in the "bin" sub-directory, i.e. C:\cygwin64\bin.
2 - Tell Jenkins where sh.exe is located.
Jenkins web console > Manage Jenkins > Configure System > Under shell, set the "Shell executable" = C:\cygwin64\bin\sh.exe > Click apply & also click save.
That's all I did to make my job pass. I was running Jenkins from a war file and I did not need to restart it to make this work.
My scenario was I need to copy n number of lines in middle, n unknown, from file 1 to file 2.

In global scope there is no semantic difference.
But you really should avoid a=0
since your setting a value to an undeclared variable.
Also use closures to avoid editing global scope at all
(function() {
// do stuff locally
// Hoist something to global scope
window.someGlobal = someLocal
}());
Always use closures and always hoist to global scope when its absolutely neccesary. You should be using asynchronous event handling for most of your communication anyway.
As @AvianMoncellor mentioned there is an IE bug with var a = foo
only declaring a global for file scope. This is an issue with IE's notorious broken interpreter. This bug does sound familiar so it's probably true.
So stick to window.globalName = someLocalpointer
It depends on what you are doing, and what you need.
If you are iterating through a collection of items, and do not care about the index values then foreach is more convenient, easier to write and safer: you can't get the number of items wrong.
If you need to process every second item in a collection for example, or process them ion the reverse order, then a for loop is the only practical way.
The biggest differences are that a foreach loop processes an instance of each element in a collection in turn, while a for loop can work with any data and is not restricted to collection elements alone. This means that a for loop can modify a collection - which is illegal and will cause an error in a foreach loop.
Here is a solution that does not involve querying INFORMATION_SCHEMA
, it simply ignores the error if the column does exist.
DROP PROCEDURE IF EXISTS `?`;
DELIMITER //
CREATE PROCEDURE `?`()
BEGIN
DECLARE CONTINUE HANDLER FOR SQLEXCEPTION BEGIN END;
ALTER TABLE `table_name` ADD COLUMN `column_name` INTEGER;
END //
DELIMITER ;
CALL `?`();
DROP PROCEDURE `?`;
P.S. Feel free to give it other name rather than ?

One of the uses which I found to be very useful is the print_function
from __future__
module.
In Python 2.7, I wanted chars from different print statements to be printed on same line without spaces.
It can be done using a comma(",") at the end, but it also appends an extra space. The above statement when used as :
from __future__ import print_function
...
print (v_num,end="")
...
This will print the value of v_num
from each iteration in a single line without spaces.

public static byte[] read(Context context, String file) throws IOException {
byte[] ret = null;
if (context != null) {
try {
InputStream inputStream = context.openFileInput(file);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
int nextByte = inputStream.read();

For tables, cellspacing and cellpadding are obsolete in HTML 5.
Now for cellspacing you have to use border-spacing. And for cellpadding you have to use border-collapse.
And make sure you don't use this in your HTML5 code. Always try to use these values in a CSS 3 file.
Here we go:
DateTime time = DateTime.Now;
Console.WriteLine(time.ToString("h:mm:ss tt"));
By default a span
is an inline
element... so that's not the default behavior.
You can make the span
behave that way by adding display: block;
to your CSS.
span {
display: block;
width: 100px;

To know the names of different desktop browsers (Firefox, IE, Opera, Edge, Chrome). Except Safari.
function getBrowserName() {

return browserName;
}
Works in the following browser versions:
Opera - 58.0.3135.79
Firefox - 65.0.2 (64-bit)
IE - 11.413.15063 (JS Fiddle no longer supports IE just paste in Console)
Edge - 44.17763.1.0
Chrome - 72.0.3626.121 (Official Build) (64-bit)
View the gist here and the fiddle here
The original code snippet no longer worked for Chrome and I forgot where I found it. It had safari before but I no longer have access to safari so I cannot verify anymore.
Only the Firefox and IE codes were part of the original snippet.
The checking for Opera, Edge, and Chrome is straight forward. They have differences in the userAgent. OPR
only exists in Opera. Edge
only exists in Edge. So to check for Chrome these string shouldn't be there.
As for the Firefox and IE, I cannot explain what they do.
I'll be adding this functionality to a package i'm writing
try this..
$(element).find("option:contains(" + theText+ ")").attr('selected', 'selected');
Not sure why SSMS doesn’t take into account execution order but it just doesn’t. This is not an issue for small databases but what if your database has 200 objects? In that case order of execution does matter because it’s not really easy to go through all of these.
For unordered scripts generated by SSMS you can go following
a) Execute script (some objects will be inserted some wont, there will be some errors)
b) Remove all objects from the script that have been added to database
c) Go back to a) until everything is eventually executed
Alternative option is to use third party tool such as ApexSQL Script or any other tools already mentioned in this thread (SSMS toolpack, Red Gate and others).
All of these will take care of the dependencies for you and save you even more time.

For my situation, I switched the value of "fork" to false, such as <fork>false</fork>
. I do not understand why, hope someone could explain to me. Thanks in advance.
Adding this to your code android:focusableInTouchMode="true"
will make sure that your keypad doesn't appear on startup for your edittext box. You want to add this line to your linear layout that contains the EditTextBox. You should be able to play with this to solve both your problems. I have tested this. Simple solution.
ie: In your app_list_view.xml file
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:focusableInTouchMode="true">
<EditText
android:id="@+id/filter_edittext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Search"
android:inputType="text"
android:maxLines="1"/>
<ListView
android:id="@id/android:list"
android:layout_height="fill_parent"
android:layout_weight="1.0"
android:layout_width="fill_parent"
android:focusable="true"
android:descendantFocusability="beforeDescendants"/>
</LinearLayout>
------------------ EDIT: To Make keyboard appear on startup -----------------------
This is to make they Keyboard appear on the username edittextbox on startup. All I've done is added an empty Scrollview to the bottom of the .xml file, this puts the first edittext into focus and pops up the keyboard. I admit this is a hack, but I am assuming you just want this to work. I've tested it, and it works fine.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingLeft="20dip"
android:paddingRight="20dip">
<EditText
android:id="@+id/userName"
android:singleLine="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Username"
android:imeOptions="actionDone"
android:inputType="text"
android:maxLines="1"
/>
<EditText
android:id="@+id/password"
android:password="true"
android:singleLine="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Password" />
<ScrollView
android:id="@+id/ScrollView01"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
</ScrollView>
</LinearLayout>
If you are looking for a more eloquent solution, I've found this question which might help you out, it is not as simple as the solution above but probably a better solution. I haven't tested it but it apparently works. I think it is similar to the solution you've tried which didn't work for you though.
Hope this is what you are looking for.
Cheers!
At work here we use Dotfuscator from PreEmptive Solutions.
Although it's impossible to protect .NET assemblies 100% Dotfuscator makes it hard enough I think. I comes with a lot of obfuscation techniques;
Cross Assembly Renaming
Renaming Schemes
Renaming Prefix
Enhanced Overload Induction
Incremental Obfuscation
HTML Renaming Report
Control Flow
String Encryption
And it turned out that they're not very expensive for small companies. They have a special pricing for small companies.
(No I'm not working for PreEmptive ;-))
There are freeware alternatives of course;
I've just used Excel 2016 to open Access 2003 tables.
To activate the cursor and select the columns you want to select use:
Windows: Alt+Shift+A
Mac: command + option + A
Linux-based OS: Alt+Shift+A
To deactivate, press the keys again.

Just for completeness - in SQL 2008 you would use the plus +
operator to perform string concatenation.
Take a look at the MSDN reference with sample code. Starting with SQL 2012, you may wish to use the new CONCAT function.

If you want make a border in a shape xml. You need to use:
For the external border,you need to use:
<stroke/>
For the internal background,you need to use:
<solid/>
If you want to set corners,you need to use:
<corners/>
If you want a padding betwen border and the internal elements,you need to use:
<padding/>
Here is a shape xml example using the above items. It works for me
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="2dp" android:color="#D0CFCC" />
<solid android:color="#F8F7F5" />
<corners android:radius="10dp" />
<padding android:left="2dp" android:top="2dp" android:right="2dp" android:bottom="2dp" />
</shape>

From MySQL docs:
A character set is a set of symbols and encodings. A collation is a set of rules for comparing characters in a character set. Let's make the distinction clear with an example of an imaginary character set.
Suppose that we have an alphabet with four letters: 'A', 'B', 'a', 'b'. We give each letter a number: 'A' = 0, 'B' = 1, 'a' = 2, 'b' = 3. The letter 'A' is a symbol, the number 0 is the encoding for 'A', and the combination of all four letters and their encodings is a character set.
Now, suppose that we want to compare two string values, 'A' and 'B'. The simplest way to do this is to look at the encodings: 0 for 'A' and 1 for 'B'. Because 0 is less than 1, we say 'A' is less than 'B'. Now, what we've just done is apply a collation to our character set. The collation is a set of rules (only one rule in this case): "compare the encodings." We call this simplest of all possible collations a binary collation.
But what if we want to say that the lowercase and uppercase letters are equivalent? Then we would have at least two rules: (1) treat the lowercase letters 'a' and 'b' as equivalent to 'A' and 'B'; (2) then compare the encodings. We call this a case-insensitive collation. It's a little more complex than a binary collation.
In real life, most character sets have many characters: not just 'A' and 'B' but whole alphabets, sometimes multiple alphabets or eastern writing systems with thousands of characters, along with many special symbols and punctuation marks. Also in real life, most collations have many rules: not just case insensitivity but also accent insensitivity (an "accent" is a mark attached to a character as in German 'ö') and multiple-character mappings (such as the rule that 'ö' = 'OE' in one of the two German collations).

I have a slightly different perspective on the difference between a DATETIME and a TIMESTAMP. A DATETIME stores a literal value of a date and time with no reference to any particular timezone. So, I can set a DATETIME column to a value such as '2019-01-16 12:15:00' to indicate precisely when my last birthday occurred. Was this Eastern Standard Time? Pacific Standard Time? Who knows? Where the current session time zone of the server comes into play occurs when you set a DATETIME column to some value such as NOW(). The value stored will be the current date and time using the current session time zone in effect. But once a DATETIME column has been set, it will display the same regardless of what the current session time zone is.
A TIMESTAMP column on the other hand takes the '2019-01-16 12:15:00' value you are setting into it and interprets it in the current session time zone to compute an internal representation relative to 1/1/1970 00:00:00 UTC. When the column is displayed, it will be converted back for display based on whatever the current session time zone is. It's a useful fiction to think of a TIMESTAMP as taking the value you are setting and converting it from the current session time zone to UTC for storing and then converting it back to the current session time zone for displaying.
If my server is in San Francisco but I am running an event in New York that starts on 9/1/1029 at 20:00, I would use a TIMESTAMP column for holding the start time, set the session time zone to 'America/New York' and set the start time to '2009-09-01 20:00:00'. If I want to know whether the event has occurred or not, regardless of the current session time zone setting I can compare the start time with NOW(). Of course, for displaying in a meaningful way to a perspective customer, I would need to set the correct session time zone. If I did not need to do time comparisons, then I would probably be better off just using a DATETIME column, which will display correctly (with an implied EST time zone) regardless of what the current session time zone is.
TIMESTAMP LIMITATION
The TIMESTAMP
type has a range of '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC and so it may not usable for your particular application. In that case you will have to use a DATETIME
type. You will, of course, always have to be concerned that the current session time zone is set properly whenever you are using this type with date functions such as NOW()
.
VSCode is a code editor, not a full IDE. Think of VSCode as a notepad on steroids with IntelliSense code completion, richer semantic code understanding of multiple languages, code refactoring, including navigation, keyboard support with customizable bindings, syntax highlighting, bracket matching, auto indentation, and snippets.
It's not meant to replace Visual Studio, but making "Visual Studio" part of the name in VSCode will of course confuse some people at first.
You want to use the TRUNCATE
command.

You can use a much simpler formula. I just created a new workbook to test it.
Column A = Date1 | Column B = Date2 | Column C = Date3
Highlight Column A and enter the conditional formatting formula:
=AND(A1>B1,A1<C1)
@John, Earlz and Nathan. The way I learned it at uni is: functions return values, methods don't. In some languages the syntax is/was actually different. Example (no specific language):
Method SetY(int y) ...
Function CalculateY(int x) As Integer ...
Most languages now use the same syntax for both versions, using void as a return type to say there actually isn't a return type. I assume it's because the syntax is more consistent and easier to change from method to function, and vice versa.
The omp_get_num_threads()
function returns the number of threads that are currently in the team executing the parallel region from which it is called. You are calling it outside of the parallel region, which is why it returns 1

A simple way to get the ids of the checked check boxes by class name:
$(".yourClassName:checkbox:checked").each(function() {
console.log($(this).attr("id"));
});
To avoid Notification icons to turn white, use "Silhouette" icons for them, ie. white-on-transparent background images. You may use Irfanview to build them:
IrfanView
, press F12 for the painting tools, clean picture if necessary (remove unwanted parts, smooth and polish)Image / Decrease Color Depth
to 2 (for a black & white picture)Image / Negative
(for a white on black picture)Image / Resize/Resample
to 144 x 144 (use Size Method "Resize" not "Resample", otherwise picture is increased to 24 color bits per pixel (24 BPP) againFile / Save as PNG
, check Show option dialog
, check Save Transparent Color
, click Save
, then click on the black color in the image to set the transparent colorAndroid seems to be using the drawable-xxhdpi picture resolution (144 x 144) only, so copy your resulting ic_notification.png
file to \AndroidStudio\Projects\...\app\src\main\res\drawable-xxhdpi
. Use .setSmallIcon(R.drawable.ic_notification)
in your code, or use getNotificationIcon()
as Daniel Saidi suggested above.
You may also use Roman Nurik's Android Asset Studio.

class _FooState extends State<Foo> {
TextEditingController _controller;
@override
void initState() {
super.initState();
_controller = new TextEditingController(text: 'Initial value');
}
@override
Widget build(BuildContext context) {
return new Column(
children: <Widget>[
new TextField(
// The TextField is first built, the controller has some initial text,
// which the TextField shows. As the user edits, the text property of
// the controller is updated.
controller: _controller,
),
new RaisedButton(
onPressed: () {
// You can also use the controller to manipuate what is shown in the
// text field. For example, the clear() method removes all the text
// from the text field.
_controller.clear();
},
child: new Text('CLEAR'),
),
],
);
}
}
Add one more condition in where clause
SELECT * FROM product
WHERE pdate >= DATEADD(day,-30,GETDATE())

WHERE DATEDIFF(day,pdate,GETDATE()) between 0 and 30
Open the file .bash_profile
in your Home folder. It is a hidden file.
Add this path below to the end export PATH line in you .bash_profile
file
:/Applications/Postgres.app/Contents/Versions/latest/bin
The symbol :
separates the paths.
If the file contains:
export PATH=/usr/bin:/bin:/usr/sbin:/sbin
it will become:
export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/Applications/Postgres.app/Contents/Versions/latest/bin
In Terminal, paste the following: defaults write com.apple.finder AppleShowAllFiles YES
You have two possibilities (for an IPv4 address) :
varchar(15)
, if your want to store the IP address as a string
192.128.0.15
for instanceinteger
(4 bytes), if you convert the IP address to an integer
3229614095
for the IP I used before
The second solution will require less space in the database, and is probably a better choice, even if it implies a bit of manipulations when storing and retrieving the data (converting it from/to a string).
About those manipulations, see the ip2long()
and long2ip()
functions, on the PHP-side, or inet_aton()
and inet_ntoa()
on the MySQL-side.
I use seperate custom functions which gets all URL Parameters and URL parts . For URL parameters, (which is the final part of an URI String, http://domain.tld/urlpart/?x=a&y=b
function getUrlVars() {
var vars = {};
var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
vars[key] = value;
});
return vars;
}
The above function will return an array consisting of url variables.
For URL Parts or functions, (which is http://domain.tld/urlpart/?x=a&y=b I use a simple uri split,
function getUrlParams() {
var vars = {};
var parts = window.location.href.split('/' );
return parts;
}
You can even combine them both to be able to use with a single call in a page or in javascript.
To set go to definition to alt + d. From the Menu Preferences > Key Bindings-User. And then add the following JSON.

you never set d[a]
to any value.
Because of this, d[a]
evaluates to undefined
, and you can't set properties on undefined
.
If you add d[a] = {}
right after d = {}
things should work as expected.
Alternatively, you could use an object initializer:
d[a] = {
greetings: b,
data: c
};
Or you could set all the properties of d
in an anonymous function instance:
d = new function () {
this[a] = {
greetings: b,
data: c
};
};
If you're in an environment that supports ES2015 features, you can use computed property names:
d = {
[a]: {
greetings: b,
data: c
}
};
With the following infix functions I can cover many common use cases pretty much the same way it can be done in Python :
class TestKotlinTernaryConditionalOperator {
@Test
fun testAndOrInfixFunctions() {
Assertions.assertThat(true and "yes" or "no").isEqualTo("yes")
Assertions.assertThat(false and "yes" or "no").isEqualTo("no")
Assertions.assertThat("A" and "yes" or "no").isEqualTo("yes")
Assertions.assertThat("" and "yes" or "no").isEqualTo("no")
Assertions.assertThat(1 and "yes" or "no").isEqualTo("yes")
Assertions.assertThat(0 and "yes" or "no").isEqualTo("no")
Assertions.assertThat(Date() and "yes" or "no").isEqualTo("yes")
@Suppress("CAST_NEVER_SUCCEEDS")
Assertions.assertThat(null as Date? and "yes" or "no").isEqualTo("no")
}
}
infix fun <E> Boolean?.and(other: E?): E? = if (this == true) other else null
infix fun <E> CharSequence?.and(other: E?): E? = if (!(this ?: "").isEmpty()) other else null
infix fun <E> Number?.and(other: E?): E? = if (this?.toInt() ?: 0 != 0) other else null
infix fun <E> Any?.and(other: E?): E? = if (this != null) other else null
infix fun <E> E?.or(other: E?): E? = this ?: other
Have a look at: Greybox
It's an awesome version of lightbox that supports forms, external web pages as well as the traditional images and slideshows. It works perfectly from a link on a webpage.
You will find many information on how to use Greybox and also some great examples. Cheers Kara
As an alternative to explicitly catching and handling the exception you could tell Oracle to catch and automatically ignore the exception by including a /*+ hint */
in the insert statement. This is a little faster than explicitly catching the exception and then articulating how it should be handled. It is also easier to setup. The downside is that you do not get any feedback from Oracle that an exception was caught.
Here is an example where we would be selecting from another table, or perhaps an inner query, and inserting the results into a table called TABLE_NAME
which has a unique constraint on a column called IDX_COL_NAME
.
INSERT /*+ ignore_row_on_dupkey_index(TABLE_NAME(IDX_COL_NAME)) */
INTO TABLE_NAME(
INDEX_COL_NAME
, col_1
, col_2
, col_3
, ...
, col_n)
SELECT
INDEX_COL_NAME
, col_1
, col_2
, col_3
, ...
, col_n);
This is not a great solution if your goal it to catch and handle (i.e. print out or update the row that is violating the constraint). But if you just wanted to catch it and ignore the violating row then then this should do the job.
Is old post but can be done like this:
if(!function_exists('strim')) :
function strim($str,$charlist=" ",$option=0){
$return='';
if(is_string($str))
{
// Translate HTML entities
$return = str_replace(" "," ",$str);
$return = strtr($return, array_flip(get_html_translation_table(HTML_ENTITIES, ENT_QUOTES)));
// Choose trim option
switch($option)
{
// Strip whitespace (and other characters) from the begin and end of string
default:
case 0:
$return = trim($return,$charlist);
break;
// Strip whitespace (and other characters) from the begin of string
case 1:
$return = ltrim($return,$charlist);
break;
// Strip whitespace (and other characters) from the end of string
case 2:
$return = rtrim($return,$charlist);
break;
}
}
return $return;
}
endif;
Standard trim() functions can be a problematic when come HTML entities. That's why i wrote "Super Trim" function what is used to handle with this problem and also you can choose is trimming from the begin, end or booth side of string.
