This is simple when doing 2 things:
tableView.rowHeight = UITableView.automaticDimension
So the layout engine can compute the cell heigth and apply the value correctly.
One more reason for this issue to happen is an earlier problem. When showing a new ViewController, instantiating the target ViewController directly will of course not load the prototype cells from the StoryBoard. The correct solution should always be to instantiate the view controller through the story board like this:
storyboard?.instantiateViewController(withIdentifier: "some_identifier")
There is a difference between the navigation bar and the status bar. The confusing part is that it looks like one solid feature at the top of the screen, but the areas can actually be separated into two distinct views; a status bar and a navigation bar. The status bar spans from y=0 to y=20 points and the navigation bar spans from y=20 to y=64 points. So the navigation bar (which is where the page title and navigation buttons go) has a height of 44 points, but the status bar and navigation bar together have a total height of 64 points.
Here is a great resource that addresses this question along with a number of other sizing idiosyncrasies in iOS7: http://ivomynttinen.com/blog/the-ios-7-design-cheat-sheet/
Thanks bhavya's solution.There have been two answers about swift, but those are not very intact. I have do that in the swift3.Below is the main code.
In AppDelegate.swift
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
// seclect the mainStoryBoard entry by whthere user is login.
let userDefaults = UserDefaults.standard
if let isLogin: Bool = userDefaults.value(forKey:Common.isLoginKey) as! Bool? {
if (!isLogin) {
self.window?.rootViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "LogIn")
}
}else {
self.window?.rootViewController = mainStoryboard.instantiateViewController(withIdentifier: "LogIn")
}
return true
}
In SignUpViewController.swift
@IBAction func userLogin(_ sender: UIButton) {
//handle your login work
UserDefaults.standard.setValue(true, forKey: Common.isLoginKey)
let delegateTemp = UIApplication.shared.delegate
delegateTemp?.window!?.rootViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "Main")
}
In logOutAction function
@IBAction func logOutAction(_ sender: UIButton) {
UserDefaults.standard.setValue(false, forKey: Common.isLoginKey)
UIApplication.shared.delegate?.window!?.rootViewController = UIStoryboard(name: "Main", bundle: nil).instantiateInitialViewController()
}
I think registering for the UIApplicationWillEnterForegroundNotification is risky as you may end up with more than one controller reacting to that notification. Nothing garanties that these controllers are still visible when the notification is received.
Here is what I do: I force call viewDidAppear on the active controller directly from the App's delegate didBecomeActive method:
Add the code below to - (void)applicationDidBecomeActive:(UIApplication *)application
UIViewController *activeController = window.rootViewController;
if ([activeController isKindOfClass:[UINavigationController class]]) {
activeController = [(UINavigationController*)window.rootViewController topViewController];
}
[activeController viewDidAppear:NO];
SIGABRT is, as stated in other answers, a general uncaught exception. You should definitely learn a little bit more about Objective-C. The problem is probably in your UITableViewDelegate method didSelectRowAtIndexPath.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
I can't tell you much more until you show us something of the code where you handle the table data source and delegate methods.
All these commands are called automatically at the appropriate times by iOS when you load/present/hide the view controller. It's important to note that these methods are attached to UIViewController
and not to UIView
s themselves. You won't get any of these features just using a UIView
.
There's great documentation on Apple's site here. Putting in simply though:
ViewDidLoad
- Called when you create the class and load from xib. Great for initial setup and one-time-only work.
ViewWillAppear
- Called right before your view appears, good for hiding/showing fields or any operations that you want to happen every time before the view is visible. Because you might be going back and forth between views, this will be called every time your view is about to appear on the screen.
ViewDidAppear
- Called after the view appears - great place to start an animations or the loading of external data from an API.
ViewWillDisappear
/DidDisappear
- Same idea as ViewWillAppear
/ViewDidAppear
.
ViewDidUnload
/ViewDidDispose
- In Objective-C, this is where you do your clean-up and release of stuff, but this is handled automatically so not much you really need to do here.
Swift 5 Here is a simple way to solve this problem
Steps:-> 1- When ViewDidLoad(), Then it will scroll 2- customTableView is IBoutlet's tableView var data: [String] = ["Hello", "This","is","Your","World"]
override func viewDidLoad() {
super.viewDidLoad()
3- In viewDidLoad we need to tell about indexPath
/// data.count-1 will give last cell
let indexPath = IndexPath(row: data.count - 1, section:0)
/// 1st Parameter: (at) will use for indexPath
/// 2nd Parameter: (at) will use for position's scroll view
/// 3rd Parameter: (animated) will show animation when screen will appear
customtableView.scrollToRow(at:indexPath, at:.top, animated:true)
/// Reload CustomTableView
customTableView.reloadData()
view.subviews.forEach { $0.removeFromSuperview() }
append a text node as follows
var td1 = document.getElementById('td1');
var text = document.createTextNode("some text");
td1.appendChild(text);
Make sure you change the right info.plist file.
This is the second time I waste time on this issue, because I didn't notice that I'm changing info.plist under MyProjectNameUITests.
Git 2.7 (Q4 2015) will introduce -local
as an instruction.
It means that, in addition to:
--date=(relative|local|default|iso|iso-strict|rfc|short|raw)
you will also have:
--date=(default-local|iso-local|iso-strict-local|rfc-local|short-local)
The -local
suffix cannot be used with raw
or relative
. Reference.
You now can ask for any date format using the local timezone. See
johnkeeping
). See commit add00ba, commit 547ed71 (03 Sep 2015) by Jeff King (peff
).
(Merged by Junio C Hamano -- gitster
-- in commit 7b09c45, 05 Oct 2015)
In particular, the last from above (commit add00ba) mentions:
date
: make "local
" orthogonal to date format:Most of our "
--date
" modes are about the format of the date: which items we show and in what order.
But "--date=local
" is a bit of an oddball. It means "show the date in the normal format, but using the local timezone".
The timezone we use is orthogonal to the actual format, and there is no reason we could not have "localized iso8601", etc.This patch adds a "
local
" boolean field to "struct date_mode
", and drops theDATE_LOCAL
element from thedate_mode_type
enum (it's now justDATE_NORMAL
pluslocal=1
).
The new feature is accessible to users by adding "-local
" to any date mode (e.g., "iso-local
"), and we retain "local
" as an alias for "default-local
" for backwards compatibility.
It's 2015. I had to go to find a blog post that would explain how to do it for the latest version of iOS and XCode with Swift so that it would work with multiple lines.

I don't know of a way to force Chrome to not clear the Network debugger, but this might accomplish what you're looking for:
window.addEventListener("beforeunload", function() { debugger; }, false)
This will pause chrome before loading the new page by hitting a breakpoint.
A cleaner way of iterating the lists is:
// initialise the collection
collection = new ArrayList<ArrayList<String>>();
// iterate
for (ArrayList<String> innerList : collection) {
for (String string : innerList) {
// do stuff with string
}
}
The dplyr
package contains summarise_all
for this aim:
library(dplyr)
# summarise_all was replaced with the summarise(acrosss(..)) syntax dplyr >=1.00
df %>% group_by(grp) %>% summarise(across(everything(), list(mean)))
#> # A tibble: 3 x 5
#> grp a b c d
#> <int> <dbl> <dbl> <dbl> <dbl>
#> 1 1 3.08 2.98 2.98 2.91
#> 2 2 3.03 3.04 2.97 2.87
#> 3 3 2.85 2.95 2.95 3.06
Alternatively, the purrrlyr
package provides the same functionality:
library(purrrlyr)
df %>% slice_rows("grp") %>% dmap(mean)
#> # A tibble: 3 x 5
#> grp a b c d
#> <int> <dbl> <dbl> <dbl> <dbl>
#> 1 1 3.08 2.98 2.98 2.91
#> 2 2 3.03 3.04 2.97 2.87
#> 3 3 2.85 2.95 2.95 3.06
Also don't forget about data.table
(use keyby
to sort sort groups):
library(data.table)
setDT(df)[, lapply(.SD, mean), keyby = grp]
#> grp a b c d
#> 1: 1 3.079412 2.979412 2.979412 2.914706
#> 2: 2 3.029126 3.038835 2.967638 2.873786
#> 3: 3 2.854701 2.948718 2.951567 3.062678
Let's try to compare performance.
library(dplyr)
library(purrrlyr)
library(data.table)
library(bench)
set.seed(123)
n <- 10000
df <- data.frame(

This one is tested and does work (based on Brad's original post):
=RIGHT(A1,LEN(A1)-FIND("|",SUBSTITUTE(A1," ","|",
LEN(A1)-LEN(SUBSTITUTE(A1," ","")))))
If your original strings could contain a pipe "|" character, then replace both in the above with some other character that won't appear in your source. (I suspect Brad's original was broken because an unprintable character was removed in the translation).
Bonus: How it works (from right to left):
LEN(A1)-LEN(SUBSTITUTE(A1," ",""))
– Count of spaces in the original string
SUBSTITUTE(A1," ","|", ... )
– Replaces just the final space with a |
FIND("|", ... )
– Finds the absolute position of that replaced |
(that was the final space)
Right(A1,LEN(A1) - ... ))
– Returns all characters after that |
EDIT: to account for the case where the source text contains no spaces, add the following to the beginning of the formula:
=IF(ISERROR(FIND(" ",A1)),A1, ... )
making the entire formula now:
=IF(ISERROR(FIND(" ",A1)),A1, RIGHT(A1,LEN(A1) - FIND("|",
SUBSTITUTE(A1," ","|",LEN(A1)-LEN(SUBSTITUTE(A1," ",""))))))
Or you can use the =IF(COUNTIF(A1,"* *")
syntax of the other version.
When the original string might contain a space at the last position add a trim function while counting all the spaces: Making the function the following:
=IF(ISERROR(FIND(" ",B2)),B2, RIGHT(B2,LEN(B2) - FIND("|",
SUBSTITUTE(B2," ","|",LEN(TRIM(B2))-LEN(SUBSTITUTE(B2," ",""))))))
I found a very nice thread on the net that explains the difference in a very straightforward way : http://www.thestudentroom.co.uk/showthread.php?t=232168.
Kruskal's algorithm will grow a solution from the cheapest edge by adding the next cheapest edge, provided that it doesn't create a cycle.
Prim's algorithm will grow a solution from a random vertex by adding the next cheapest vertex, the vertex that is not currently in the solution but connected to it by the cheapest edge.
Here attached is an interesting sheet on that topic.
If you implement both Kruskal and Prim, in their optimal form : with a union find and a finbonacci heap respectively, then you will note how Kruskal is easy to implement compared to Prim.
Prim is harder with a fibonacci heap mainly because you have to maintain a book-keeping table to record the bi-directional link between graph nodes and heap nodes. With a Union Find, it's the opposite, the structure is simple and can even produce directly the mst at almost no additional cost.

Java Web Start is a good technology for installing Java rich clients off the internet direct to the end user's desktop (whether the OS is Windows, Mac or *nix). It comes complete with desktop integration and automatic updates, among many other goodies.

If you want the column is BIT and NOT NULL, you should put ISNULL before the CAST.
ISNULL(
CAST (
CASE
WHEN FC.CourseId IS NOT NULL THEN 1 ELSE 0
END
AS BIT)
,0) AS IsCoursedBased
In your case it should be:
Select convert(datetime,convert(varchar(10),GRADUATION_DATE,120)) as
'GRADUATION_DATE' from mydb

You can set title timeout & even sleep to schedule it for latter & \n for new line
also you get back the key press into a variable (%pop.key%
).

Check out a related question on the unix.com forum.
I tried the suggestions before but none worked for me (tested them in Chrome), so I wrote my own code - and it works fine in Firefox, IE, Safari, Chrome...
In Textarea:
onfocus() = sendCursorToEnd(this);
In Javascript:
function sendCursorToEnd(obj) {
var value = obj.value; //store the value of the element
var message = "";
if (value != "") {
message = value + "\n";
};
$(obj).focus().val(message);}
Why not use Model.update? After all you're not using the found user for anything else than to update it's properties:
User.update({username: oldUsername}, {
username: newUser.username,
password: newUser.password,
rights: newUser.rights
}, function(err, numberAffected, rawResponse) {
//handle it
})
This functionality can also be added using JavaScript. Carto.net has an example:
http://old.carto.net/papers/svg/textFlow/
Something else that also might be useful to are you are editable text areas:
You can set your hash directly to URL too.
window.location.hash = "YourHash";
The result : http://url#YourHash
It is indeed possible.
Here is an example calling the Weather SOAP Service using plain requests lib:
import requests
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
#headers = {'content-type': 'application/soap+xml'}
headers = {'content-type': 'text/xml'}
body = """<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:ns0="http://ws.cdyne.com/WeatherWS/" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<ns1:Body><ns0:GetWeatherInformation/></ns1:Body>
</SOAP-ENV:Envelope>"""
response = requests.post(url,data=body,headers=headers)
print response.content
Some notes:
application/soap+xml
is probably the more correct header to use (but the weatherservice prefers text/xml
For example:
from jinja2 import Environment, PackageLoader
env = Environment(loader=PackageLoader('myapp', 'templates'))
template = env.get_template('soaprequests/WeatherSericeRequest.xml')
body = template.render()
Some people have mentioned the suds library. Suds is probably the more correct way to be interacting with SOAP, but I often find that it panics a little when you have WDSLs that are badly formed (which, TBH, is more likely than not when you're dealing with an institution that still uses SOAP ;) ).
You can do the above with suds like so:
from suds.client import Client
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
client = Client(url)
print client ## shows the details of this service
result = client.service.GetWeatherInformation()
print result
Note: when using suds, you will almost always end up needing to use the doctor!
Finally, a little bonus for debugging SOAP; TCPdump is your friend. On Mac, you can run TCPdump like so:
sudo tcpdump -As 0
This can be helpful for inspecting the requests that actually go over the wire.
The above two code snippets are also available as gists:
There is a neat way of doing this.
If it's an Unit Test you can do this:
@RunWith(MockitoJUnitRunner.class)
public class MyUnitTest {
@Mock
private MyFirstMock myFirstMock;
@Mock
private MySecondMock mySecondMock;
@Spy
private MySpiedClass mySpiedClass = new MySpiedClass();
// It's gonna inject the 2 mocks and the spied object per reflection to this object
// The java doc of @InjectMocks explains it really well how and when it does the injection
@InjectMocks
private MyClassToTest myClassToTest;
@Test
public void testSomething() {
}
}
EDIT: If it's an Integration test you can do this(not intended to be used that way with Spring. Just showcase that you can initialize mocks with diferent Runners):
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("aplicationContext.xml")
public class MyIntegrationTest {
@Mock
private MyFirstMock myFirstMock;
@Mock
private MySecondMock mySecondMock;
@Spy
private MySpiedClass mySpiedClass = new MySpiedClass();
// It's gonna inject the 2 mocks and the spied object per reflection to this object
// The java doc of @InjectMocks explains it really well how and when it does the injection
@InjectMocks
private MyClassToTest myClassToTest;
@Before
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
}
@Test
public void testSomething() {
}
}
You might be looking for process.env.PORT
. This allows you to dynamically set the listening port using what are called "environment variables". The Node.js code would look like this:
const port = process.env.PORT || 3000;
app.listen(port, () => {console.log(`Listening on port ${port}...`)});
You can even manually set the dynamic variable in the terminal using export PORT=5000
, or whatever port you want.
I was looking for same thing but in number, means from integer xx hour, xx minutes and AM/PM to 24 hour format xx hour and xx minutes, so here what i have done:
private static final int AM = 0;
private static final int PM = 1;
/**
* Based on concept: day start from 00:00AM and ends at 11:59PM,
* afternoon 12 is 12PM, 12:xxAM is basically 00:xxAM
* @param hour12Format
* @param amPm
* @return
*/
private int get24FormatHour(int hour12Format,int amPm){
if(hour12Format==12 && amPm==AM){
hour12Format=0;
}
if(amPm == PM && hour12Format!=12){
hour12Format+=12;
}
return hour12Format;
}`
private int minutesTillMidnight(int hour12Format,int minutes, int amPm){
int hour24Format=get24FormatHour(hour12Format,amPm);
System.out.println("24 Format :"+hour24Format+":"+minutes);
return (hour24Format*60)+minutes;
}
As others have said you can't do what you are asking. If you describe the problem you are trying to solve maybe someone can help?
E.g.
Edit The address you see on the server shouldn't be the ISP's address, as you say that would be a huge range. The address for a home user on broadband will be the address at their router, so every device inside the house will appear on the outside to be the same, but the router uses NAT to ensure that traffic is routed to each device correctly. For users accessing from an office environment the address may well be the same for all users. Sites that use IP address for ID run the risk of getting it very wrong - the examples you give are good ones and they often fail. For example my office is in the UK, the breakout point (where I "appear" to be on the internet) is in another country where our main IT facility is, so from my office my IP address appears to be not in the UK. For this reason I can't access UK only web content, such as the BBC iPlayer). At any given time there would be hundreds, or even thousands, of people at my company who appear to be accessing the web from the same IP address.
When you are writing server code you can never be sure what the IP address you see is referring to. Some users like it this way. Some people deliberately use a proxy or VPN to further confound you.
When you say your machine address is different to the IP address shown on StackOverflow, how are you finding out your machine address? If you are just looking locally using ipconfig
or something like that I would expect it to be different for the reasons I outlined above. If you want to double check what the outside world thinks have a look at whatismyipaddress.com/.
This Wikipedia link on NAT will provide you some background on this.
An addition to the other answers concerning object comparison:
== compares objects using the name of the object and their values. If two objects are of the same type and have the same member values, $a == $b
yields true.
=== compares the internal object id of the objects. Even if the members are equal, $a !== $b
if they are not exactly the same object.
class TestClassA {
public $a;
}
class TestClassB {
public $a;
}
$a1 = new TestClassA();
$a2 = new TestClassA();
$b = new TestClassB();
$a1->a = 10;
$a2->a = 10;
$b->a = 10;
$a1 == $a1;
$a1 == $a2; // Same members
$a1 != $b; // Different classes
$a1 === $a1;
$a1 !== $a2; // Not the same object
E = exponent expression, simply means power(10, n) or 10 ^ n
F = fraction expression, default 6 digits precision
G = gerneral expression, somehow smart to show the number in a concise way (but really?)
See the below example,
The code
void main(int argc, char* argv[])
{
double a = 4.5;
printf("=>>>> below is the example for printf 4.5\n");
printf("%%e %e\n",a);
printf("%%f %f\n",a);
printf("%%g %g\n",a);
printf("%%E %E\n",a);
printf("%%F %F\n",a);
printf("%%G %G\n",a);
double b = 1.79e308;
printf("=>>>> below is the exbmple for printf 1.79*10^308\n");
printf("%%e %e\n",b);
printf("%%f %f\n",b);
printf("%%g %g\n",b);
printf("%%E %E\n",b);
printf("%%F %F\n",b);
printf("%%G %G\n",b);
double d = 2.25074e-308;
printf("=>>>> below is the example for printf 2.25074*10^-308\n");

Axios.post solution with IE and other browsers
I've found some incredible solutions here. But they frequently don't take into account problems with IE browser. Maybe it will save some time to somebody else.
axios.post("/yourUrl"
, data,
{responseType: 'blob'}
).then(function (response) {
let fileName = response.headers["content-disposition"].split("filename=")[1];
if (window.navigator && window.navigator.msSaveOrOpenBlob) { // IE variant
window.navigator.msSaveOrOpenBlob(new Blob([response.data], {type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'}),
fileName);
} else {
const url = window.URL.createObjectURL(new Blob([response.data], {type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'}));
const link = document.createElement('a');
link.href = url;
link.setAttribute('download', response.headers["content-disposition"].split("filename=")[1]);
document.body.appendChild(link);
link.click();
}
}
);
example above is for excel files, but with little changes can be applied to any format.
And on server I've done this to send an excel file.
response.contentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
response.addHeader(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=exceptions.xlsx")
The way I have sorted HTML tables in the browser uses plain, unadorned Javascript.
The basic process is:
The table should, of course, be nice HTML. Something like this...
<table>
<thead>
<tr><th>Name</th><th>Age</th></tr>
</thead>
<tbody>
<tr><td>Sioned</td><td>62</td></tr>
<tr><td>Dylan</td><td>37</td></tr>
...etc...
</tbody>
</table>
So, first adding the click handlers...
const table = document.querySelector('table'); //get the table to be sorted
table.querySelectorAll('th') // get all the table header elements
.forEach((element, columnNo)=>{ // add a click handler for each
element.addEventListener('click', event => {
sortTable(table, columnNo); //call a function which sorts the table by a given column number
})
})
This won't work right now because the sortTable
function which is called in the event handler doesn't exist.
Lets write it...
function sortTable(table, sortColumn){
// get the data from the table cells
const tableBody = table.querySelector('tbody')
const tableData = table2data(tableBody);
// sort the extracted data
tableData.sort((a, b)=>{
if(a[sortColumn] > b[sortColumn]){
return 1;
}
return -1;
})
// put the sorted data back into the table
data2table(tableBody, tableData);
}
So now we get to the meat of the problem, we need to make the functions table2data
to get data out of the table, and data2table
to put it back in once sorted.
Here they are ...
// this function gets data from the rows and cells
// within an html tbody element
function table2data(tableBody){
const tableData = []; // create the array that'll hold the data rows
tableBody.querySelectorAll('tr')
.forEach(row=>{ // for each table row...
const rowData = []; // make an array for that row
row.querySelectorAll('td') // for each cell in that row
.forEach(cell=>{
rowData.push(cell.innerText); // add it to the row data
})
tableData.push(rowData); // add the full row to the table data
});
return tableData;
}
// this function puts data into an html tbody element
function data2table(tableBody, tableData){
tableBody.querySelectorAll('tr') // for each table row...
.forEach((row, i)=>{
const rowData = tableData[i]; // get the array for the row data
row.querySelectorAll('td') // for each table cell ...
.forEach((cell, j)=>{
cell.innerText = rowData[j]; // put the appropriate array element into the cell
})
tableData.push(rowData);
});
}
And that should do it.
A couple of things that you may wish to add (or reasons why you may wish to use an off the shelf solution): An option to change the direction and type of sort i.e. you may wish to sort some columns numerically ("10" > "2"
is false because they're strings, probably not what you want). The ability to mark a column as sorted. Some kind of data validation.
Clone-: It will create exactly duplicate copy of your remote repository project in your local machine.
Pull-: Suppose two or more than two people are sharing the same repository. (Suppose another person name is Syam) (A Repository is a place where your project exist in Github) So if Syam does some changes in the same project in his local and pushes it to the remote repository So whatever the changes Syam did those changes will not reflect in your local. So to reflect those new changes in your local you have to use git pull. Overall we use git pull to update the project.
So basically we use git clone only once whereas we use git pull many times.
In my case, log4net wasn't logging properly due to having a space in my project name. Drove me nuts why the same code worked just fine in a different project, but didn't in the new one. Spaces. A simple space.
So, beware spaces in project names. I've learned my lesson.
Starting with SQL Server 2012, you could use TRY_PARSE or TRY_CONVERT.
SELECT TRY_PARSE(MyVarcharCol as int)
SELECT TRY_CONVERT(int, MyVarcharCol)
While calling your sub functions from your main functions you can convert the variables into int and then call. Please refer the below code:
import sys
print("Welcome to Calculator\n")
print("Please find the options:\n" + "1. Addition\n" + "2. Subtraction\n" +
"3. Multiplication\n" + "4. Division\n" + "5. Exponential\n" + "6. Quit\n")
def calculator():
choice = input("Enter choice\n")
if int(choice) == 1:
a = input("Enter first number\n")
b = input("Enter second number\n")
add(int(a), int(b))
if int(choice) == 2:
a = input("Enter first number\n")
b = input("Enter second number\n")
diff(int(a), int(b))
if int(choice) == 3:
a = input("Enter first number\n")
b = input("Enter second number\n")
mult(int(a), int(b))
if int(choice) == 4:
a = input("Enter first number\n")
b = input("Enter second number\n")
div(float(a), float(b))
if int(choice) == 5:
a = input("Enter the base number\n")
b = input("Enter the exponential\n")
exp(int(a), int(b))
if int(choice) == 6:
print("Bye")
sys.exit(0)
def add(a, b):
c = a+b
print("Sum of {} and {} is {}".format(a, b, c))
def diff(a,b):
c = a-b
print("Difference between {} and {} is {}".format(a, b, c))
def mult(a, b):
c = a*b
print("The Product of {} and {} is {}".format(a, b, c))
def div(a, b):
c = a/b
print("The Quotient of {} and {} is {}".format(a, b, c))
def exp(a, b):
c = a**b
print("The result of {} to the power of {} is {}".format(a, b, c))
calculator()
Here what I did is I called each of the function while converting the parameters inputted to int. I hope this has been helpful.
In your case it could be changed like this:
if choice == "0":
numberA = raw_input("Enter your first number: ")
numberB = raw_input("Enter your second number: ")
print "Your result is:"
print addition(int(numberA), int(numberB))
If you want to call a bash script using python, here is a simple method to load a file from a folder in S3 bucket to a local folder (in a Linux machine) :
import boto3
import subprocess
import os
###TOEDIT###
my_bucket_name = "your_my_bucket_name"
bucket_folder_name = "your_bucket_folder_name"
local_folder_path = "your_local_folder_path"
###TOEDIT###
# 1.Load thes list of files existing in the bucket folder
FILES_NAMES = []
s3 = boto3.resource('s3')
my_bucket = s3.Bucket('{}'.format(my_bucket_name))
for object_summary in my_bucket.objects.filter(Prefix="{}/".format(bucket_folder_name)):
# print(object_summary.key)
FILES_NAMES.append(object_summary.key)
# 2.List only new files that do not exist in local folder (to not copy everything!)
new_filenames = list(set(FILES_NAMES )-set(os.listdir(local_folder_path)))
# 3.Time to load files in your destination folder
for new_filename in new_filenames:
upload_S3files_CMD = """aws s3 cp s3://{}/{}/{} {}""".format(my_bucket_name,bucket_folder_name,new_filename ,local_folder_path)
subprocess_call = subprocess.call([upload_S3files_CMD], shell=True)
if subprocess_call != 0:
print("ALERT: loading files not working correctly, please re-check new loaded files")

as @chepner says in his comment you are comparing $i to a fixed string.
To expand and rectify the situation you should use [[ ]] with the regex operator =~
eg:
for i in $(ls);do
if [[ $i =~ .*\.java$ ]];then
echo "I want to do something with the file $i"
fi
done
the regex to the right of =~ is tested against the value of the left hand operator and should not be quoted, ( quoted will not error but will compare against a fixed string and so will most likely fail"
but @chepner 's answer above using glob is a much more efficient mechanism.
Use image as background sized to layout:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="@+id/imgPlaylistItemBg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:maxHeight="0dp"
android:scaleType="fitXY"
android:src="@drawable/img_dsh" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</FrameLayout>
You can test if a string ends with work followed by one character like this:
theString.matches(".*work.$");
If the trailing character is optional you can use this:
theString.matches(".*work.?$");
To make sure the last character is a period .
or a slash /
you can use this:
theString.matches(".*work[./]$");
To test for work followed by an optional period or slash you can use this:
theString.matches(".*work[./]?$");
To test for work surrounded by periods or slashes, you could do this:
theString.matches(".*[./]work[./]$");
If the tokens before and after work must match each other, you could do this:
theString.matches(".*([./])work\\1$");
Your exact requirement isn't precisely defined, but I think it would be something like this:
theString.matches(".*work[,./]?$");
In other words:
,
.
OR /
Explanation of various regex items:
. -- any character
* -- zero or more of the preceeding expression
$ -- the end of the line/input
? -- zero or one of the preceeding expression
[./,] -- either a period or a slash or a comma
[abc] -- matches a, b, or c
[abc]* -- zero or more of (a, b, or c)
[abc]? -- zero or one of (a, b, or c)
enclosing a pattern in parentheses is called "grouping"
([abc])blah\\1 -- a, b, or c followed by blah followed by "the first group"
Here's a test harness to play with:
class TestStuff {
public static void main (String[] args) {
String[] testStrings = {
"work.",
"work-",
"workp",
"/foo/work.",
"/bar/work",
"baz/work.",
"baz.funk.work.",
"funk.work",
"jazz/junk/foo/work.",
"funk/punk/work/",
"/funk/foo/bar/work",
"/funk/foo/bar/work/",
".funk.foo.bar.work.",
".funk.foo.bar.work",
"goo/balls/work/",
"goo/balls/work/funk"
};
for (String t : testStrings) {
print("word: " + t + " ---> " + matchesIt(t));
}
}
public static boolean matchesIt(String s) {
return s.matches(".*([./,])work\\1?$");
}
public static void print(Object o) {
String s = (o == null) ? "null" : o.toString();
System.out.println(o);
}
}
You can use attribute selectors but they won't work in IE6 like meder said, there are javascript workarounds to that tho. Check Selectivizr
More detailed into on attribute selectors: http://www.css3.info/preview/attribute-selectors/
/* turns all input fields that have a name that starts with "go" red */
input[name^="go"] { color: red }
With ES6, this is possible in exactly the manner you have described; a detailed description can be found in the documentation.
Default parameters in JavaScript can be implemented in mainly two ways:
function myfunc(a, b)
{
// use this if you specifically want to know if b was passed
if (b === undefined) {
// b was not passed
}
// use this if you know that a truthy value comparison will be enough
if (b) {
// b was passed and has truthy value
} else {
// b was not passed or has falsy value
}
// use this to set b to a default value (using truthy comparison)
b = b || "default value";
}
The expression b || "default value"
evaluates the value AND existence of b
and returns the value of "default value"
if b
either doesn't exist or is falsy.
Alternative declaration:
function myfunc(a)
{
var b;
// use this to determine whether b was passed or not
if (arguments.length == 1) {
// b was not passed
} else {
b = arguments[1]; // take second argument
}
}
The special "array" arguments
is available inside the function; it contains all the arguments, starting from index 0
to N - 1
(where N
is the number of arguments passed).
This is typically used to support an unknown number of optional parameters (of the same type); however, stating the expected arguments is preferred!
Although undefined
is not writable since ES5, some browsers are known to not enforce this. There are two alternatives you could use if you're worried about this:
b === void 0;
typeof b === 'undefined'; // also works for undeclared variables
It's probably because asterisk is not running on your server.
Try to run it with this command :
asterisk -vvvvvvc
You'll enter into the Asterisk CLI and if something goes wrong you'll see it. After that you can quit the CLI by entering the exit
command. Then you can reconnect to the CLI by typing asterisk -r
. All this commands assumed you're the root user. If you are not root prefix them by sudo
, by example sudo asterisk -vvvvvvc
.
Hope it helps, regards, Duc.
Why don't you try this
for(int i=0; i < dt.Rows.Count; i++)
{
// u can use here the i
}
You can run the web server on any port. 80 is just convention as are 8080 (web server on unprivileged port) and 443 (web server + ssl). However if you're looking to see some web site by pointing your browser to a different port you're probably out of luck. Unless the web server is being run on that port explicitly you'll just get an error message.
(Assuming Excel 2003...)
When using the Text-to-Columns Wizard has, in Step 3 you can dictate the data type for each of the columns. Click on the column in the preview and change the misbehaving column from "General" to "Text."
In conf directory of apache tomcat you can find context.xml file. In that edit tag as <Context reloadable="true">. this should solve the issue and you need not restart the server
Now ES6 have arrow function it really helpful if you really confuse with bind(this) expression you can try arrow function
This is how I do.
componentWillMount() {
ListApi.getList()
.then(JsonList => this.setState({ List: JsonList }));
}
//Above method equalent to this...
componentWillMount() {
ListApi.getList()
.then(function (JsonList) {
this.setState({ List: JsonList });
}.bind(this));
}
A simple and intuitive way would be to use shuf
.
Example:
Assume words.txt
as:
the
an
linux
ubuntu
life
good
breeze
To shuffle the lines, do:
$ shuf words.txt
which would throws the shuffled lines to standard output; So, you've to pipe it to an output file like:
$ shuf words.txt > shuffled_words.txt
One such shuffle run could yield:
breeze
the
linux
an
ubuntu
good
life
You are missing the selector in the .on
function:
.on(eventType, selector, function)
This selector is very important!
If new HTML is being injected into the page, select the elements and attach event handlers after the new HTML is placed into the page. Or, use delegated events to attach an event handler

This can be accomplished by Unmarshaling into a map[string]json.RawMessage
.
var objmap map[string]json.RawMessage
err := json.Unmarshal(data, &objmap)
To further parse sendMsg
, you could then do something like:
var s sendMsg
err = json.Unmarshal(objmap["sendMsg"], &s)
For say
, you can do the same thing and unmarshal into a string:
var str string
err = json.Unmarshal(objmap["say"], &str)
EDIT: Keep in mind you will also need to export the variables in your sendMsg struct to unmarshal correctly. So your struct definition would be:
type sendMsg struct {
User string
Msg string
}
I wouldn't call those different kind of streams. The Stream class have CanRead and CanWrite properties that tell you if the particular stream can be read from and written to.
The major difference between different stream classes (such as MemoryStream vs FileStream) is the backing store - where the data is read from or where it's written to. It's kind of obvious from the name. A MemoryStream stores the data in memory only, a FileStream is backed by a file on disk, a NetworkStream reads data from the network and so on.
I removed the bugs in above code and got below results: Also I am unsure given how NetSerializer requires you to register the types you are serializing, what kind of compatibility or performance differences that could potentially make.

Very annoying, no cookie file exmpale on the official website https://ec.haxx.se/http/http-cookies.
Finnaly, I find it does not work, if your file content is just copyied like this
foo1=bar;foo2=bar2
I gusess the format must looks the style said by @Agustí Sánchez . You can test it by -c to create a cookie file on a website.
So try this way, it works
curl -H "Cookie:`cat ./my.cookie`" http://xxxx.com
You can just copy the cookie from chrome console network tab.
I just spent a few hours on this error, and while the other answers here helped me understand what was going on, they did not fix my particular problem.
I am working on a project that compiles using both clang++
and g++
. I was having no linking issues using clang++
, but was getting the undefined reference to 'typeinfo for
error with g++
.
The important point: Linking order MATTERS with g++
. If you list the libraries you want to link in an order which is incorrect you can get the typeinfo
error.
See this SO question for more details on linking order with gcc
/g++
.
In addition to the answers above the command below will also work. I post it because it makes more sense to me. In each case it is 'using x-value-column: y-value-column'
plot 'ls.dat' using 1:2, 'ls.dat' using 1:3, 'ls.dat' using 1:4
note that the command above assumes that you have a file named ls.dat
with tab separated columns of data where column 1 is x, column 2 is y1, column 3 is y2 and column 4 is y3.
First, bootstrap-theme.css
is nothing else but equivalent of Bootstrap 2.x style in Bootstrap 3. If you really want to use it, just add it ALONG with bootstrap.css
(minified version will work too).
For normal users. Open the inspect window of current page. And type in:
l = document.getElementsByTagName("a");
for (var i =0; i<l.length; i++) {
l[i].href = "";
}
Then you shall not see the url links in print preview.
Don't try to use grep for this, use awk instead. To match 2 regexps R1 and R2 in grep you'd think it would be:
grep 'R1.*R2|R2.*R1'
while in awk it'd be:
awk '/R1/ && /R2/'
but what if R2
overlaps with or is a subset of R1
? That grep command simply would not work while the awk command would. Lets say you want to find lines that contain the
and heat
:
$ echo 'theatre' | grep 'the.*heat|heat.*the'
$ echo 'theatre' | awk '/the/ && /heat/'
theatre
You'd have to use 2 greps and a pipe for that:
$ echo 'theatre' | grep 'the' | grep 'heat'
theatre
and of course if you had actually required them to be separate you can always write in awk the same regexp as you used in grep and there are alternative awk solutions that don't involve repeating the regexps in every possible sequence.
Putting that aside, what if you wanted to extend your solution to match 3 regexps R1, R2, and R3. In grep that'd be one of these poor choices:
grep 'R1.*R2.*R3|R1.*R3.*R2|R2.*R1.*R3|R2.*R3.*R1|R3.*R1.*R2|R3.*R2.*R1' file
grep R1 file | grep R2 | grep R3
while in awk it'd be the concise, obvious, simple, efficient:
awk '/R1/ && /R2/ && /R3/'
Now, what if you actually wanted to match literal strings S1 and S2 instead of regexps R1 and R2? You simply can't do that in one call to grep, you have to either write code to escape all RE metachars before calling grep:
S1=$(sed 's/[^^]/[&]/g; s/\^/\\^/g' <<< 'R1')
S2=$(sed 's/[^^]/[&]/g; s/\^/\\^/g' <<< 'R2')
grep 'S1.*S2|S2.*S1'
or again use 2 greps and a pipe:
grep -F 'S1' file | grep -F 'S2'
which again are poor choices whereas with awk you simply use a string operator instead of regexp operator:
awk 'index($0,S1) && index($0.S2)'
Now, what if you wanted to match 2 regexps in a paragraph rather than a line? Can't be done in grep, trivial in awk:
awk -v RS='' '/R1/ && /R2/'
How about across a whole file? Again can't be done in grep and trivial in awk (this time I'm using GNU awk for multi-char RS for conciseness but it's not much more code in any awk or you can pick a control-char you know won't be in the input for the RS to do the same):
awk -v RS='^$' '/R1/ && /R2/'
So - if you want to find multiple regexps or strings in a line or paragraph or file then don't use grep, use awk.

I implemented something like this, using pickle for persistance and using sha1 for short almost-certainly-unique IDs. Basically the cache hashed the code of the function and the hist of arguments to get a sha1 then looked for a file with that sha1 in the name. If it existed, it opened it and returned the result; if not, it calls the function and saves the result (optionally only saving if it took a certain amount of time to process).
That said, I'd swear I found an existing module that did this and find myself here trying to find that module... The closest I can find is this, which looks about right: http://chase-seibert.github.io/blog/2011/11/23/pythondjango-disk-based-caching-decorator.html
The only problem I see with that is it wouldn't work well for large inputs since it hashes str(arg), which isn't unique for giant arrays.
It would be nice if there were a unique_hash() protocol that had a class return a secure hash of its contents. I basically manually implemented that for the types I cared about.
This is not a direct answer to your question (which was answered pretty well already). However, having had times bite me on the fundament several times, I cannot stress enough that it would behoove you to look closely at what your time.struct_time object is providing, vs. what other time fields may have.
Assuming you have both a time.struct_time object, and some other date/time string, compare the two, and be sure you are not losing data and inadvertently creating a naive datetime object, when you can do otherwise.
For example, the excellent feedparser module will return a "published" field and may return a time.struct_time object in its "published_parsed" field:
time.struct_time(tm_year=2013, tm_mon=9, tm_mday=9, tm_hour=23, tm_min=57, tm_sec=42, tm_wday=0, tm_yday=252, tm_isdst=0)
Now note what you actually get with the "published" field.
Mon, 09 Sep 2013 19:57:42 -0400
By Stallman's Beard! Timezone information!
In this case, the lazy man might want to use the excellent dateutil module to keep the timezone information:
from dateutil import parser
dt = parser.parse(entry["published"])
print "published", entry["published"])
print "dt", dt
print "utcoffset", dt.utcoffset()
print "tzinfo", dt.tzinfo
print "dst", dt.dst()
which gives us:
published Mon, 09 Sep 2013 19:57:42 -0400
dt 2013-09-09 19:57:42-04:00
utcoffset -1 day, 20:00:00
tzinfo tzoffset(None, -14400)
dst 0:00:00
One could then use the timezone-aware datetime object to normalize all time to UTC or whatever you think is awesome.
I just had a very similar issues with gradle builds / adding .jar library. I got it working by a combination of :

You could use a subselect:
SELECT row
FROM table
WHERE id=(
SELECT max(id) FROM table
)
Note that if the value of max(id)
is not unique, multiple rows are returned.
If you only want one such row, use @MichaelMior's answer,
SELECT row from table ORDER BY id DESC LIMIT 1
There's a tidier way to include variables inside the escaped calc, as explained in this post: CSS3 calc() function doesn't work with Less #974
@variable: 2em;
body{ width: calc(~"100% - @{variable} * 2");}
By using the curly brackets you don't need to close and reopen the escaping quotes.
You'll be wanting to use the 'read' command
while read name
do
echo "$name"
done < names.txt
Note that "$name" is quoted -- if it's not, it will be split using the characters in $IFS
as delimiters. This probably won't be noticed if you're just echoing the variable, but if your file contains a list of file names which you want to copy, those will get broken down by $IFS
if the variable is unquoted, which is not what you want or expect.
If you want to use Mike Clark's approach (loading into a variable rather than using read), you can do it without the use of cat
:
NAMES="$(< scripts/names.txt)" #names from names.txt file
for NAME in $NAMES; do
echo "$NAME"
done
The problem with this is that it loads the whole file into $NAMES
, when you read it back out, you can either get the whole file (if quoted) or the file broken down by $IFS
, if not quoted. By default, this will give you individual words, not individual lines. So if the name "Mary Jane" appeared on a line, you would get "Mary" and "Jane" as two separate names. Using read
will get around this... although you could also change the value of $IFS
The simplest way of doing this which I find useful is the below.
This might not be the official way but it works well.
Suppose you have a project named "XYZ
" on your PC.
Now you want to make a git repo of this project on github and use its functionalities.
Step 1: go to "www.github.com
"
Step 2: create a repository with a "README.md
" file (name it as you like it)
Step 3: clone the repository to your PC.
Step 4: In the cloned folder you will get two things : ".git
" folder and a "README.md
" file. Copy these two in your project folder "XYZ
".
Step 5: Delete the cloned repo.
Step 6: add, commit and push all the files and folders of your project.
Now, you can just use your project "XYZ
" as a git repository.
There's many forms of timeout, are you after the connection timeout, request timeout or time to live (time before TCP connection stops).
The default TimeToLive on Firefox is 115s (network.http.keep-alive.timeout)
The default connection timeout on Firefox is 250s (network.http.connection-retry-timeout)
The default request timeout for Firefox is 30s (network.http.pipelining.read-timeout).
The time it takes to do an HttpRequest depends on if a connection has been made this has to be within 250s which I'm guessing you're not after. You're probably after the request timeout which I think is 30,000ms (30s) so to conclude I'd say it's timing out with a connection time out that's why you got a response back after ~150s though I haven't really tested this.

There is no datetime dtype to be set for read_csv as csv files can only contain strings, integers and floats.
Setting a dtype to datetime will make pandas interpret the datetime as an object, meaning you will end up with a string.
The pandas.read_csv()
function has a keyword argument called parse_dates
Using this you can on the fly convert strings, floats or integers into datetimes using the default date_parser
(dateutil.parser.parser
)
headers = ['col1', 'col2', 'col3', 'col4']
dtypes = {'col1': 'str', 'col2': 'str', 'col3': 'str', 'col4': 'float'}
parse_dates = ['col1', 'col2']
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes, parse_dates=parse_dates)
This will cause pandas to read col1
and col2
as strings, which they most likely are ("2016-05-05" etc.) and after having read the string, the date_parser for each column will act upon that string and give back whatever that function returns.
The pandas.read_csv()
function also has a keyword argument called date_parser
Setting this to a lambda function will make that particular function be used for the parsing of the dates.
You have to give it the function, not the execution of the function, thus this is Correct
date_parser = pd.datetools.to_datetime
This is incorrect:
date_parser = pd.datetools.to_datetime()
pd.datetools.to_datetime
has been relocated to date_parser = pd.to_datetime

i use dumpsys to catch if app is crashed and process is still active. situation i used it is to find about remote machine app is crashed or not.
dumpsys | grep myapp | grep "Application Error"
or
adb shell dumpsys | grep myapp | grep Error
or anything that helps...etc
if app is not running you will get nothing as result. When app is stoped messsage is shown on screen by android, process is still active and if you check via "ps" command or anything else, you will see process state is not showing any error or crash meaning. But when you click button to close message, app process will cleaned from process list. so catching crash state without any code in application is hard to find. but dumpsys helps you.

Stack overflow means exactly that: a stack overflows. Usually there's a one stack in the program that contains local-scope variables and addresses where to return when execution of a routine ends. That stack tends to be a fixed memory range somewhere in the memory, therefore it's limited how much it can contain values.
If the stack is empty you can't pop, if you do you'll get stack underflow error.
If the stack is full you can't push, if you do you'll get stack overflow error.
So stack overflow appears where you allocate too much into the stack. For instance, in the mentioned recursion.
Some implementations optimize out some forms of recursions. Tail recursion in particular. Tail recursive routines are form of routines where the recursive call appears as a final thing what the routine does. Such routine call gets simply reduced into a jump.
Some implementations go so far as implement their own stacks for recursion, therefore they allow the recursion to continue until the system runs out of memory.
Easiest thing you could try would be to increase your stack size if you can. If you can't do that though, the second best thing would be to look whether there's something that clearly causes the stack overflow. Try it by printing something before and after the call into routine. This helps you to find out the failing routine.

I'm finding out that the location of the log4j.properties file depends on the type of Eclipse project.
Specifically, for an Eclipse Dynamic Web Project, most of the answers that involve adding the log4j.properties to the war file do not actually add the properties file in the correct location, especially for Tomcat/Apache.
Here is some of my research and my solution to the issue (again specifically for a Dynamic Web Project running on Tomcat/Apache 6.0)
Please refer to this article around how Tomcat will load classes. It's different than the normal class loader for Java. (https://www.mulesoft.com/tcat/tomcat-classpath) Note that it only looks in two places in the war file, WEB-INF/classes and WEB-INF/lib.
Note that with a Dynamic Web Project, it is not wise to store your .properties file in the build/../classes directory, as this directory is wiped whenever you clean-build your project.
Tomcat does not handle .property files in the WEB-INF/lib location.
You cannot store the log4j.properties file in the src directory, as Eclipse abstracts that directory away from your view.
The one way I have found to resolve this is to alter the build and add an additional directory that will eventually load into the WEB-INF/classes directory in the war file. Specifically....
(1) Right click your project in the project explorer, select 'New'->'Folder'. You can name the folder anything, but the standard in this case is 'resources'. The new folder should appear at the root level of your project.
(2) Move the log4j.properties file into this new folder.
(3) Right click the project again, and select 'Build-Path'->'Configure Build Path'. Select the 'Sources' tab. Click the 'Add Folder' button. Browse to find your new folder you created in step (1) above. Select 'OK'.
(4) Once back to the eclipse Project Explorer view, note that the folder has now moved to the 'Java Resources' area (ie it's no longer at the root due to eclipse presentation abstraction).
(5) Clean build your project.
(6) To validate that the .properties file now exists in WEB-INF/classes in your war file, export a war file to an easy location (right click Project -> Export -> War file) and checkout the contents. Note that the log4j.properties file now appears in the WEB-INF/classes.
(7) Promote your project to Tomcat/Apache and note that log4j now works.
Now that log4j works, start logging, solve world problems, take some time off, and enjoy a tasty adult beverage.

"""Generate a random datetime between `start` and `end`"""
return start + datetime.timedelta(
# Get a random amount of seconds between `start` and `end`

Note that both start
and end
arguments should be datetime
objects. If
you've got strings instead, it's fairly easy to convert. The other answers point
to some ways to do so.
This is a shortcut for $(document).ready()
, which is executed when the browser has finished loading the page (meaning here, "when the DOM is available"). See http://www.learningjquery.com/2006/09/introducing-document-ready. If you are trying to call example()
before the browser has finished loading the page, it may not work.
To get the label of a specific option in a dropdown yo can ty this --
$('.class_of_dropdown > option[value='value_to_be_searched']').html();
or
$('#id_of_dropdown > option[value='value_to_be_Searched']').html();
Define OFFSET for the query. For example
page 1 - (records 01-10): offset = 0, limit=10;
page 2 - (records 11-20) offset = 10, limit =10;
and use the following query :
SELECT column FROM table LIMIT {someLimit} OFFSET {someOffset};
example for page 2:
SELECT column FROM table
LIMIT 10 OFFSET 10;
I had the same problem. Initially I had setup Eclipse CDT with Cygwing & was working smoothly. One day there happened a problem due to which I had to reset windows. After that when I opened Eclipse I started facing the issue described above. This is how I solved it.
First I searched that in the error the PATH variable value is same as the PATH variable of windows ( just by manual comparison of both two values ). I found that to be same. Now I realized that it is a PATH problem.
Then started looking for Cygwin whether it is there or not? It was there. I located & found that it exists in

One way would be with sed
. For example:
echo $name | sed -e 's?http://www\.??'
Normally the sed
regular expressions are delimited by `/', but you can use '?' since you're searching for '/'. Here's another bash trick. @DigitalTrauma's answer reminded me that I ought to suggest it. It's similar:
echo ${name#http://www.}
(DigitalTrauma also gets credit for reminding me that the "http://" needs to be handled.)
You can simply add this class.
.btn {

word-wrap: break-word;

PostAsJsonAsync
is no longer in the System.Net.Http.dll
(.NET 4.5.2). You can add a reference to System.Net.Http.Formatting.dll
, but this actually belongs to an older version. I ran into problems with this on our TeamCity build server, these two wouldn't cooperate together.
Alternatively, you can replace PostAsJsonAsync
with a PostAsync
call, which is just part of new dll.
Replace
var response = client.PostAsJsonAsync("api/AgentCollection", user).Result;
With:
var response = client.PostAsync("api/AgentCollection", new StringContent(
new JavaScriptSerializer().Serialize(user), Encoding.UTF8, "application/json")).Result;
Note that JavaScriptSerializer
is in the namespace: System.Web.Script.Serialization
.
You will have to add an assembly reference in your csproj: System.Web.Extensions.dll

If you don't have any other indexes or sorted information for your objects, then you will have to iterate until such an object is found:
next(obj for obj in objs if obj.val == 5)
This is however faster than a complete list comprehension. Compare these two:
[i for i in xrange(100000) if i == 1000][0]
next(i for i in xrange(100000) if i == 1000)
The first one needs 5.75ms, the second one 58.3µs (100 times faster because the loop 100 times shorter).
The first answer does't work anymore.

As AlienWebGuy said, you can use background-image. I'd suggest you use background, but it will need three more properties after the URL:
background: url("http://www.gentleface.com/i/free_toolbar_icons_16x16_black.png") 0 0 no-repeat;
Explanation: the two zeros are x and y positioning for the image; if you want to adjust where the background image displays, play around with these (you can use both positive and negative values, e.g: 1px or -1px).
No-repeat says you don't want the image to repeat across the entire background. This can also be repeat-x and repeat-y.
You can add script tags in your HTML document, ideally inside the which points to your javascript files. Order of the script tags are important. Load the jQuery before your script files if you want to use jQuery from your script.
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="relative/path/to/your/javascript.js"></script>
Then in your javascript file you can refer to jQuery either using $
sign or jQuery
.
Example:
jQuery.each(arr, function(i) { console.log(i); });
OK, normally it does not a good practice to add 2 answers in same thread, but I did not want to edit/delete my previous answer, since it can help on another manner.
Now, I created, much more comprehensive, and easy to understand, run-to-learn console app snippet below.

You can do this:
add-pssnapin Microsoft.Exchange.Management.PowerShell.E2010
and most of it will work (although MS support will tell you that doing this is not supported because it bypasses RBAC).
I've seen issues with some cmdlets (specifically enable/disable UMmailbox) not working with just the snapin loaded.
In Exchange 2010, they basically don't support using Powershell outside of the the implicit remoting environment of an actual EMS shell.
You can submit the IP you receive to an online geolocation service, such as http://www.geoplugin.net/json.gp?ip=<your ip here>&jsoncallback=<suitable javascript function in your source>
, then including the source it returns which will run the function you specify in jsoncallback
with the geolocation information.
Alternatively, you may want to look into HTML5's geolocation features -- you can see a demo of it in action here. The advantage of this is that you do not need to make requests to foreign servers, but it may not work on browsers that do not support HTML5.
In the windows when we open jupyter notebook in command prompt we can see the instructions in first 10 lines in that there is one instruction- "to open notebook, open this file in browser file://C:/Users/{username}/appdata/roaming/jupyetr/runtime/nbserver-xywz-open.html " , open this html with browser of your choice.
If there is no selection, you can use the properties .selectionStart
or .selectionEnd
(with no selection they're equal).
var cursorPosition = $('#myTextarea').prop("selectionStart");
Note that this is not supported in older browsers, most notably IE8-. There you'll have to work with text ranges, but it's a complete frustration.
I believe there is a library somewhere which is dedicated to getting and setting selections/cursor positions in input elements, though. I can't recall its name, but there seem to be dozens on articles about this subject.
Okay so you are trying to get a bitmap from a file? Title says URL. Anyways, when you are getting files from external storage in Android you should never use a direct path. Instead call getExternalStorageDirectory() like so:
File bitmapFile = new File(Environment.getExternalStorageDirectory() + "/" + PATH_TO_IMAGE);
Bitmap bitmap = BitmapFactory.decodeFile(bitmapFile);
getExternalStorageDirectory() gives you the path to the SD card. Also you need to declare the WRITE_EXTERNAL_STORAGE permission in the Manifest.
Try HKEY_LOCAL_MACHINE\SYSTEM\Setup\SystemPartition
Simple like that:
date("Y-m-d", strtotime("-1 day"));
date("Y-m-d", strtotime("-1 months"))
This worked for me. I added alias and restarted my terminal:
alias python=/usr/local/bin/python3
HTML Component
<input type="text" [formControl]="txtValue">
TS Component
public txtValue = new FormControl('', { validators:[Validators.required] });
We can use this method to save using API. LearnersModules is the module file on our Angular files SaveSampleExams is the service file is one function method.
> this.service.SaveSampleExams(LearnersModules).subscribe(
> (data) => {
> this.dataSaved = true;
> LearnersModules.txtValue = this.txtValue.value;
> });
I had the same problem of "gpg: keyserver timed out" with a couple of different servers. Finally, it turned out that I didn't need to do that manually at all. On a Debian system, the simple solution which fixed it was just (as root or precede with sudo):
aptitude install debian-archive-keyring
In case it is some other keyring you need, check out
apt-cache search keyring | grep debian
My squeeze system shows all these:
debian-archive-keyring - GnuPG archive keys of the Debian archive
debian-edu-archive-keyring - GnuPG archive keys of the Debian Edu archive
debian-keyring - GnuPG keys of Debian Developers
debian-ports-archive-keyring - GnuPG archive keys of the debian-ports archive
emdebian-archive-keyring - GnuPG archive keys for the emdebian repository
You can do it via ssh.
ssh [email protected] "python ./hello.py"
You can also edit the script in ssh using a textual editor or X11 forwarding.
You can find more about it in the bundler website (emphasis added below for your convenience):
After developing your application for a while, check in the application together with the Gemfile and Gemfile.lock snapshot. Now, your repository has a record of the exact versions of all of the gems that you used the last time you know for sure that the application worked...
This is important: the Gemfile.lock makes your application a single package of both your own code and the third-party code it ran the last time you know for sure that everything worked. Specifying exact versions of the third-party code you depend on in your Gemfile would not provide the same guarantee, because gems usually declare a range of versions for their dependencies.
The desired assembly has appeared in the list now.
I can only speculate what caused it to appear, but I suspect it is the fact that I went File ? New ? Project ? ASP.NET Web Application, which I had never done before. It is possible that this caused some sort of late initialisation to happen and the list to be populated with additional assemblies for Web development.
I think your EmpID
column is string and you forget to use ' '
in your value.
Because when you write EmpID=" + id.Text
, your command looks like EmpID = 12345
instead of EmpID = '12345'
Change your SqlCommand
to
SqlCommand cmd = new SqlCommand("SELECT EmpName FROM Employee WHERE EmpID='" + id.Text +"'", con);
Or as a better way you can (and should) always use parameterized queries
. This kind of string concatenations are open for SQL Injection
attacks.
SqlCommand cmd = new SqlCommand("SELECT EmpName FROM Employee WHERE EmpID = @id", con);
cmd.Parameters.AddWithValue("@id", id.Text);
I think your EmpID
column keeps your employee id's, so it's type should some numerical type instead of character.

If Modal State is not Valid & the error cannot be seen on screen because your control is in collapsed accordion, then you can return the HttpStatusCode so that the actual error message is shown if you do F12. Also you can log this error to ELMAH error log. Below is the code
if (!ModelState.IsValid)
{
var message = string.Join(" | ", ModelState.Values
.SelectMany(v => v.Errors)
.Select(e => e.ErrorMessage));
//Log This exception to ELMAH:
Exception exception = new Exception(message.ToString());
Elmah.ErrorSignal.FromCurrentContext().Raise(exception);
//Return Status Code:
return new HttpStatusCodeResult(HttpStatusCode.BadRequest, message);
}
But please note that this code will log all validation errors. So this should be used only when such situation arises where you cannot see the errors on screen.
You have init'd myRequest
as NSMutableURLRequest
, you need this:
var URLRequest
Swift is ditching both the NSMutable...
thing. Just use var
for the new classes.
JSP is a Java view technology running on the server machine which allows you to write template text in client side languages (like HTML, CSS, JavaScript, ect.). JSP supports taglibs, which are backed by pieces of Java code that let you control the page flow or output dynamically. A well-known taglib is JSTL. JSP also supports Expression Language, which can be used to access backend data (via attributes available in the page, request, session and application scopes), mostly in combination with taglibs.
When a JSP is requested for the first time or when the web app starts up, the servlet container will compile it into a class extending HttpServlet
and use it during the web app's lifetime. You can find the generated source code in the server's work directory. In for example Tomcat, it's the /work
directory. On a JSP request, the servlet container will execute the compiled JSP class and send the generated output (usually just HTML/CSS/JS) through the web server over a network to the client side, which in turn displays it in the web browser.
Servlet is a Java application programming interface (API) running on the server machine, which intercepts requests made by the client and generates/sends a response. A well-known example is the HttpServlet
which provides methods to hook on HTTP requests using the popular HTTP methods such as GET
and POST
. You can configure HttpServlet
s to listen to a certain HTTP URL pattern, which is configurable in web.xml
, or more recently with Java EE 6, with @WebServlet
annotation.
When a Servlet is first requested or during web app startup, the servlet container will create an instance of it and keep it in memory during the web app's lifetime. The same instance will be reused for every incoming request whose URL matches the servlet's URL pattern. You can access the request data by HttpServletRequest
and handle the response by HttpServletResponse
. Both objects are available as method arguments inside any of the overridden methods of HttpServlet
, such as doGet()
and doPost()
.
JSF is a component based MVC framework which is built on top of the Servlet API and provides components via taglibs which can be used in JSP or any other Java based view technology such as Facelets. Facelets is much more suited to JSF than JSP. It namely provides great templating capabilities such as composite components, while JSP basically only offers the <jsp:include>
for templating in JSF, so that you're forced to create custom components with raw Java code (which is a bit opaque and a lot of tedious work) when you want to replace a repeated group of components with a single component. Since JSF 2.0, JSP has been deprecated as view technology in favor of Facelets.
Note: JSP itself is NOT deprecated, just the combination of JSF with JSP is deprecated.
Note: JSP has great templating abilities by means of Taglibs, especially the (Tag File) variant. JSP templating in combination with JSF is what is lacking.
As being a MVC (Model-View-Controller) framework, JSF provides the FacesServlet
as the sole request-response Controller. It takes all the standard and tedious HTTP request/response work from your hands, such as gathering user input, validating/converting them, putting them in model objects, invoking actions and rendering the response. This way you end up with basically a JSP or Facelets (XHTML) page for View and a JavaBean class as Model. The JSF components are used to bind the view with the model (such as your ASP.NET web control does) and the FacesServlet
uses the JSF component tree to do all the work.
I found that I had to use .setAttribute('crossOrigin', '')
and had to append a timestamp to the URL's query string to avoid a 304 response lacking the Access-Control-Allow-Origin
header.
This gives me
var url = 'http://lorempixel.com/g/400/200/';
var imgObj = new Image();
imgObj.src = url + '?' + new Date().getTime();
imgObj.setAttribute('crossOrigin', '');
Find the folder containing the shared library libopencv_core.so.2.4 using the following command line.
sudo find / -name "libopencv_core.so.2.4*"
Then I got the result:
/usr/local/lib/libopencv_core.so.2.4.
Create a file called
/etc/ld.so.conf.d/opencv.conf
and write to it the path to the folder where the binary is stored.For example, I wrote /usr/local/lib/
to my opencv.conf
file.
Run the command line as follows.
sudo ldconfig -v
Try to run the command again.
SSIS (SQL Server Integration Services) is an upgrade of DTS (Data Transformation Services), which is a feature of the previous version of SQL Server. SSIS packages can be created in BIDS (Business Intelligence Development Studio). These can be used to merge data from heterogeneous data sources into SQL Server. They can also be used to populate data warehouses, to clean and standardize data, and to automate administrative tasks.
SQL Server Integration Services (SSIS) is a component of Microsoft SQL Server 2005. It replaces Data Transformation Services, which has been a feature of SQL Server since Version 7.0. Unlike DTS, which was included in all versions, SSIS is only available in the "Standard" and "Enterprise" editions. Integration Services provides a platform to build data integration and workflow applications. The primary use for SSIS is data warehousing as the product features a fast and flexible tool for data extraction, transformation, and loading (ETL).). The tool may also be used to automate maintenance of SQL Server databases, update multidimensional cube data, and perform other functions.
You can set :

Here is a JQuery&JavaScript solutions to print div as it styles(with internal and external css)
$(document).ready(function() {
$("#btnPrint").live("click", function () {//$btnPrint is button which will trigger print
var divContents = $(".order_summery").html();//div which have to print
var printWindow = window.open('', '', 'height=700,width=900');
printWindow.document.write('<html><head><title></title>');
printWindow.document.write('<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.0/css/bootstrap.min.css" >');//external styles
printWindow.document.write('<link rel="stylesheet" href="/css/custom.css" type="text/css"/>');
printWindow.document.write('</head><body>');
printWindow.document.write(divContents);
printWindow.document.write('</body></html>');
printWindow.document.close();
printWindow.onload=function(){
printWindow.focus();
printWindow.print();
printWindow.close();
}
});
});
This will print your div in new window.
Button to trigger event
<input type="button" id="btnPrint" value="Print This">
The finally block is always executed unless there is abnormal program termination, either resulting from a JVM crash or from a call to System.exit(0)
.
On top of that, any value returned from within the finally block will override the value returned prior to execution of the finally block, so be careful of checking all exit points when using try finally.
Whatever advice path you go down, make a copy of your project folder, and rename the external most one to reflect what XCode version it is being opened in. Your choice on whether you want it to update syntax or not, but the main reason for all this bovver is your storyboard will be altered just by looking. It may be resolved by the time a new reader coming across this in the future, or
If you write both back and frontend, another simple solution is to attach a "/" at the end of the URL at front. If so, you don't need to change your backend...

If you are logged in into psql on the Linux shell the command is:
\i fileName.sql
for an absolute path and
\ir filename.sql
for the relative path from where you have called psql.
The correct way of referring to a method parameter is like this:
break x if ((int)strcmp(y, "hello")) == 0
On some implementations gdb might not know the return type of strcmp. That means you would have to cast, otherwise it would always evaluate to true!
If you do not care about tick shifting (depending on how long did it took previously on each execution) and you do not want to use channels, it's possible to use native range function.
i.e.
package main
import "fmt"
import "time"
func main() {
go heartBeat()
time.Sleep(time.Second * 5)
}
func heartBeat() {
for range time.Tick(time.Second * 1) {
fmt.Println("Foo")
}
}
When the LinkButton Enabled property is false it just renders a standard hyperlink. When you right click any disabled hyperlink you don't get the option to open in anything.
try
lbnkVidTtile1.Enabled = true;
I'm sorry if I misunderstood. Could I just make sure that you understand the purpose of a LinkButton? It is to give the appearance of a HyperLink but the behaviour of a Button. This means that it will have an anchor tag, but there is JavaScript wired up that performs a PostBack to the page. If you want to link to another page then it is recommended here that you use a standard HyperLink control.
I've encountered this today and the accepted answers did not work for me. Here is how I did it.
if( $('#div-id *').length === 0 ) {
// your code here...
}
My solution checks if there are any elements inside the div so it would still mark the div empty if there is only text inside it.
Here is a more efficient way of fading out an element:
function fade(element) {
var op = 1; // initial opacity
var timer = setInterval(function () {
if (op <= 0.1){
clearInterval(timer);
element.style.display = 'none';
}
element.style.opacity = op;
element.style.filter = 'alpha(opacity=' + op * 100 + ")";
op -= op * 0.1;
}, 50);
}
you can do the reverse for fade in
setInterval or setTimeout should not get a string as argument
google the evils of eval to know why
And here is a more efficient way of fading in an element.
function unfade(element) {
var op = 0.1; // initial opacity
element.style.display = 'block';
var timer = setInterval(function () {
if (op >= 1){
clearInterval(timer);
}
element.style.opacity = op;
element.style.filter = 'alpha(opacity=' + op * 100 + ")";
op += op * 0.1;
}, 10);
}
You're inserting values for OperationId
that is an identity column.
You can turn on identity insert on the table like this so that you can specify your own identity values.
SET IDENTITY_INSERT Table1 ON
INSERT INTO Table1
/*Note the column list is REQUIRED here, not optional*/
(OperationID,
OpDescription,
FilterID)
VALUES (20,
'Hierachy Update',
1)
SET IDENTITY_INSERT Table1 OFF
The new version of SharePoint and Office (SharePoint 2010 and Office 2010) respectively are supposed to allow for this. This also includes the web based versions. I have seen Word and Excel in action do this, not sure about other client applications.
I am not sure about the specific implementation features you are asking about in terms of security though. Sorry.,=
Here is a discussion

@broc.seib has a sophisticated answer, I just want to point out that instead of pressing y
to get the permanent link, github now has a very simple UI that helps you to achieve it
Select line by clicking on the line number or select multiple lines by downholding shift
(same as how you select multiple folders in file explorer)
on the right hand corner of the first line you selected, expand ...
and click copy permalink

It boils down to adding android:stretchColumns="*"
to your TableLayout
root and setting android:layout_width="0dp"
to all the children in your TableRow
s.
<TableLayout
android:stretchColumns="*" // Optionally use numbered list "0,1,2,3,..."
>
<TableRow
android:layout_width="0dp"
>
The best
and the rest
Depending on the version you are running. It is basically the same just go to
File -> Invalidate caches, then restart Intellij
or
File -> Invalidate caches / Restart
The main difference is that in older versions you had to manually restart as cache files are not removed until you restart. The newer versions will ask if you also want to restart.
As seen here on this official Jetbrains help page
You can also try delete caches manually in the system
folder for your installed version. The location of this folder depends on your OS and version installed.
Windows Vista, 7, 8, 10
<SYSTEM DRIVE>\Users\<USER ACCOUNT NAME>\.<PRODUCT><VERSION>
Linux/Unix
~/.<PRODUCT><VERSION>
Mac OS
~/Library/Caches/<PRODUCT><VERSION>
Read this for more details on cache locations.
You can set the default value of your Id in your db to newsequentialid() or newid(). Then the identity configuration of EF should work.
import java.io.RandomAccessFile;
RandomAccessFile f = new RandomAccessFile(fileName, "r");
byte[] b = new byte[(int)f.length()];
f.readFully(b);
Documentation for Java 8: http://docs.oracle.com/javase/8/docs/api/java/io/RandomAccessFile.html
with open(destPath+'\\'+csvXML, 'a+') as csvFile:
writer = csv.writer(csvFile, delimiter=';', lineterminator='\r')
writer.writerows(xmlList)
The "lineterminator='\r'" permit to pass to next row, without empty row between two.
I'd do it like this:
[id^="product"] {
...
}
Ideally, use a class. This is what classes are for:
<div id="product176" class="product"></div>
<div id="product177" class="product"></div>
<div id="product178" class="product"></div>
And now the selector becomes:
.product {
...
}
I have also faced this problem and the solution is:
I added this code again and my program ran accurately:
Application.Run(new PayrollSystem());
//File name this code removed by me accidentally.
If you have QT and if you are lazy to implement a function and stuff you can use
std::string str;
QString(str).toStdWString()

I think this may help you to resolve your problem.
as explained here
With help from numpy one can calculate for example a linear fitting.
# plot the data itself
pylab.plot(x,y,'o')
# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])
You can also use vector::insert.
std::vector<int> v;
int a[5] = {2, 5, 8, 11, 14};
v.insert(v.end(), a, a+5);
Edit:
Of course, in real-world programming you should use:
v.insert(v.end(), a, a+(sizeof(a)/sizeof(a[0]))); // C++03
v.insert(v.end(), std::begin(a), std::end(a)); // C++11
In C# 7.0 (Visual Studio 2017) there is a new construction to do that:
(string first, string middle, string last) LookupName(long id)
This may be a case where debugging the debugger might be useful. Essentially if you follow the instructions here you can run two ide's and one will debug into the other. If you un your application in one, you can sometimes catch errors that you otherwise miss. Its worth a try.
I recently published a project that allows PHP to obtain and interact with a real Bash shell. Get it here: https://github.com/merlinthemagic/MTS The shell has a pty (pseudo terminal device, same as you would have in i.e. a ssh session), and you can get the shell as root if desired. Not sure you need root to execute your script, but given you mention sudo it is likely.
After downloading you would simply use the following code:
$shell = \MTS\Factories::getDevices()->getLocalHost()->getShell('bash', true);
$return1 = $shell->exeCmd('/path/to/osascript myscript.scpt');
This issue has been discussed in https://github.com/twbs/bootstrap/issues/10203 By now, there is no plan to change Grid because compatibility reasons.

Also, by using double quotes you create String

card = random.choice(cards)
cardsLeft = cards.replace(card, '', 1)
How to remove one character from a string: Here is an example where there is a stack of cards represented as characters in a string. One of them is drawn (import random module for the random.choice() function, that picks a random character in the string). A new string, cardsLeft, is created to hold the remaining cards given by the string function replace() where the last parameter indicates that only one "card" is to be replaced by the empty string...
Convert the number to a string and throw away everything after the decimal.
trunc = function(n) { return Number(String(n).replace(/\..*/, "")) }
trunc(-1.5) === -1
trunc(1.5) === 1
Edit 2013-07-10
As pointed out by minitech and on second thought the string method does seem a bit excessive. So comparing the various methods listed here and elsewhere:
function trunc1(n){ return parseInt(n, 10); }
function trunc2(n){ return n - n % 1; }
function trunc3(n) { return Math[n > 0 ? "floor" : "ceil"](n); }
function trunc4(n) { return Number(String(n).replace(/\..*/, "")); }
function getRandomNumber() { return Math.random() * 10; }
function test(func, desc) {
var t1, t2;
var ave = 0;
for (var k = 0; k < 10; k++) {
t1 = new Date().getTime();
for (var i = 0; i < 1000000; i++) {
window[func](getRandomNumber());
}
t2 = new Date().getTime();
ave += t2 - t1;
}
console.info(desc + " => " + (ave / 10));
}
test("trunc1", "parseInt");
test("trunc2", "mod");
test("trunc3", "Math");
test("trunc4", "String");
The results, which may vary based on the hardware, are as follows:
parseInt => 258.7
mod => 246.2
Math => 243.8
String => 1373.1
The Math.floor / ceil method being marginally faster than parseInt and mod. String does perform poorly compared to the other methods.
I tried to create a byte array like this
byte[] bytes = new byte[Integer.MAX_VALUE-x];
System.out.println(bytes.length);
With this run configuration:
-Xms4G -Xmx4G
And java version:
Openjdk version "1.8.0_141"
OpenJDK Runtime Environment (build 1.8.0_141-b16)
OpenJDK 64-Bit Server VM (build 25.141-b16, mixed mode)
It only works for x >= 2 which means the maximum size of an array is Integer.MAX_VALUE-2
Values above that give
Exception in thread "main" java.lang.OutOfMemoryError: Requested array size exceeds VM limit at Main.main(Main.java:6)
I will advise you to uninstall the bs4 library by using this command:
pip uninstall bs4
and then install it using this command:
sudo apt-get install python3-bs4
I was facing the same problem in my Linux Ubuntu when I used the following command for installing bs4 library:
pip install bs4
This will do the trick

The short answer is: don't. (...) You really can't. And that's a good thing
I'd like to set the record straight regarding this:
NodeJS does support Synchronous Requests. It wasn't designed to support them out of the box, but there are a few workarounds if you are keen enough, here is an example:
var request = require('sync-request'),
res1, res2, ucomp, vcomp;
try {
res1 = request('GET', base + u_ext);
res2 = request('GET', base + v_ext);
ucomp = res1.split('\n')[1].split(', ')[1];
vcomp = res2.split('\n')[1].split(', ')[1];
doSomething(ucomp, vcomp);
} catch (e) {}
When you pop the hood open on the 'sync-request' library you can see that this runs a synchronous child process in the background. And as is explained in the sync-request README it should be used very judiciously. This approach locks the main thread, and that is bad for performance.
However, in some cases there is little or no advantage to be gained by writing an asynchronous solution (compared to the certain harm you are doing by writing code that is harder to read).
This is the default assumption held by many of the HTTP request libraries in other languages (Python, Java, C# etc), and that philosophy can also be carried to JavaScript. A language is a tool for solving problems after all, and sometimes you may not want to use callbacks if the benefits outweigh the disadvantages.
For JavaScript purists this may rankle of heresy, but I'm a pragmatist so I can clearly see that the simplicity of using synchronous requests helps if you find yourself in some of the following scenarios:
Test Automation (tests are usually synchronous by nature).
Quick API mash-ups (ie hackathon, proof of concept works etc).
Simple examples to help beginners (before and after).
Be warned that the code above should not be used for production. If you are going to run a proper API then use callbacks, use promises, use async/await, or whatever, but avoid synchronous code unless you want to incur a significant cost for wasted CPU time on your server.
You could use LINQBridge (MIT Licensed) to add support for lambda expressions to C# 2.0:
With Studio's multi-targeting and LINQBridge, you'll be able to write local (LINQ to Objects) queries using the full power of the C# 3.0 compiler—and yet your programs will require only Framework 2.0.
If it just a question of providing expensive tasks, in case of php-fpm is supported, why not to use fastcgi_finish_request()
function?
This function flushes all response data to the client and finishes the request. This allows for time consuming tasks to be performed without leaving the connection to the client open.
You don't really use asynchronicity in this way:
fastcgi_finish_request()
.Once again php-fpm is needed.

The answer is .IsPostBack
as suggested by @Kundan Singh Chouhan. Just to add to it, move your code into a separate method from Page_Load
private void PopulateFields()
{
using(SqlConnection con1 = new SqlConnection("Data Source=USER-PC;Initial Catalog=webservice_database;Integrated Security=True"))
{
DataTable dt = new DataTable();
con1.Open();
SqlDataReader myReader = null;
SqlCommand myCommand = new SqlCommand("select * from customer_registration where username='" + Session["username"] + "'", con1);
myReader = myCommand.ExecuteReader();
while (myReader.Read())
{
TextBoxPassword.Text = (myReader["password"].ToString());
TextBoxRPassword.Text = (myReader["retypepassword"].ToString());
DropDownListGender.SelectedItem.Text = (myReader["gender"].ToString());
DropDownListMonth.Text = (myReader["birth"].ToString());
DropDownListYear.Text = (myReader["birth"].ToString());
TextBoxAddress.Text = (myReader["address"].ToString());
TextBoxCity.Text = (myReader["city"].ToString());
DropDownListCountry.SelectedItem.Text = (myReader["country"].ToString());
TextBoxPostcode.Text = (myReader["postcode"].ToString());
TextBoxEmail.Text = (myReader["email"].ToString());
TextBoxCarno.Text = (myReader["carno"].ToString());
}
con1.Close();
}//end using
}
Then call it in your Page_Load
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
PopulateFields();
}
}
SELECT username FROM all_users ORDER BY username;
Doing the following in a command prompt works for me, also adding to my User environment variables worked fine as well:

This is to help anyone who comes here looking for a solution that wants a pure approach. I would recommend understanding this problem because it can happen in lots of different places not just with a JS Buffer object. By understanding why the problem exists and how to solve it you will improve your ability to solve other problems in the future since this one is so fundamental.
For those of us that have to deal with these problems in other languages it is quite natural to devise a solution, but there are people who may not realize how to abstract away the complexities and implement a generally efficient dynamic buffer. The code below may have potential to be optimized further.
I have left the read method unimplemented to keep the example small in size.
The realloc
function in C (or any language dealing with intrinsic allocations) does not guarantee that the allocation will be expanded in size with out moving the existing data - although sometimes it is possible. Therefore most applications when needing to store a unknown amount of data will use a method like below and not constantly reallocate, unless the reallocation is very infrequent. This is essentially how most file systems handle writing data to a file. The file system simply allocates another node and keeps all the nodes linked together, and when you read from it the complexity is abstracted away so that the file/buffer appears to be a single contiguous buffer.
For those of you who wish to understand the difficulty in just simply providing a high performance dynamic buffer you only need to view the code below, and also do some research on memory heap algorithms and how the memory heap works for programs.
Most languages will provide a fixed size buffer for performance reasons, and then provide another version that is dynamic in size. Some language systems opt for a third-party system where they keep the core functionality minimal (core distribution) and encourage developers to create libraries to solve additional or higher level problems. This is why you may question why a language does not provide some functionality. This small core functionality allows costs to be reduced in maintaining and enhancing the language, however you end up having to write your own implementations or depending on a third-party.

Often when there is a drastic difference from run to run of a query I find that it is often one of 5 issues.
STATISTICS - Statistics are out of date. A database stores statistics on the range and distribution of the types of values in various column on tables and indexes. This helps the query engine to develop a "Plan" of attack for how it will do the query, for example the type of method it will use to match keys between tables using a hash or looking through the entire set. You can call Update Statistics on the entire database or just certain tables or indexes. This slows down the query from one run to another because when statistics are out of date, its likely the query plan is not optimal for the newly inserted or changed data for the same query (explained more later below). It may not be proper to Update Statistics immediately on a Production database as there will be some overhead, slow down and lag depending on the amount of data to sample. You can also choose to use a Full Scan or Sampling to update Statistics. If you look at the Query Plan, you can then also view the statistics on the Indexes in use such using the command DBCC SHOW_STATISTICS (tablename, indexname). This will show you the distribution and ranges of the keys that the query plan is using to base its approach on.
PARAMETER SNIFFING - The query plan that is cached is not optimal for the particular parameters you are passing in, even though the query itself has not changed. For example, if you pass in a parameter which only retrieves 10 out of 1,000,000 rows, then the query plan created may use a Hash Join, however if the parameter you pass in will use 750,000 of the 1,000,000 rows, the plan created may be an index scan or table scan. In such a situation you can tell the SQL statement to use the option OPTION (RECOMPILE) or an SP to use WITH RECOMPILE. To tell the Engine this is a "Single Use Plan" and not to use a Cached Plan which likely does not apply. There is no rule on how to make this decision, it depends on knowing the way the query will be used by users.
INDEXES - Its possible that the query haven't changed, but a change elsewhere such as the removal of a very useful index has slowed down the query.
ROWS CHANGED - The rows you are querying drastically changes from call to call. Usually statistics are automatically updated in these cases. However if you are building dynamic SQL or calling SQL within a tight loop, there is a possibility you are using an outdated Query Plan based on the wrong drastic number of rows or statistics. Again in this case OPTION (RECOMPILE) is useful.
THE LOGIC Its the Logic, your query is no longer efficient, it was fine for a small number of rows, but no longer scales. This usually involves more indepth analysis of the Query Plan. For example, you can no longer do things in bulk, but have to Chunk things and do smaller Commits, or your Cross Product was fine for a smaller set but now takes up CPU and Memory as it scales larger, this may also be true for using DISTINCT, you are calling a function for every row, your key matches don't use an index because of CASTING type conversion or NULLS or functions... Too many possibilities here.
In general when you write a query, you should have some mental picture of roughly how certain data is distributed within your table. A column for example, can have an evenly distributed number of different values, or it can be skewed, 80% of the time have a specific set of values, whether the distribution will varying frequently over time or be fairly static. This will give you a better idea of how to build an efficient query. But also when debugging query performance have a basis for building a hypothesis as to why it is slow or inefficient.
You can use lynx with -stdin and -dump options to achieve that:
<?php
$descriptorspec = array(
0 => array("pipe", "r"), // stdin is a pipe that the child will read from
1 => array("pipe", "w"), // stdout is a pipe that the child will write to
2 => array("file", "/tmp/htmp2txt.log", "a") // stderr is a file to write to
);
$process = proc_open('lynx -stdin -dump 2>&1', $descriptorspec, $pipes, '/tmp', NULL);
if (is_resource($process)) {
// $pipes now looks like this:
// 0 => writeable handle connected to child stdin
// 1 => readable handle connected to child stdout
// Any error output will be appended to htmp2txt.log
$stdin = $pipes[0];
fwrite($stdin, <<<'EOT'

If you remember which branch was checked out before (e.g. master
) you could simply
git checkout master
to get out of detached HEAD state.
Generally speaking: git checkout <branchname>
will get you out of that.
If you don't remember the last branch name, try
git checkout -
This also tries to check out your last checked out branch.
I think it can help you:
CREATE PROCEDURE DEPT_COUNT
(
@DEPT_NAME VARCHAR(20), -- Input parameter
@D_COUNT INT OUTPUT -- Output parameter
-- Remember parameters begin with "@"
)
AS -- You miss this word in your example
BEGIN
SELECT COUNT(*)
INTO #D_COUNT -- Into a Temp Table (prefix "#")
FROM INSTRUCTOR
WHERE INSTRUCTOR.DEPT_NAME = DEPT_COUNT.DEPT_NAME
END
Then, you can call the SP like this way, for example:
DECLARE @COUNTER INT
EXEC DEPT_COUNT 'DeptName', @COUNTER OUTPUT
SELECT @COUNTER
If you want to append
text or html to span
then you can do it as below.
$('p span#add_here').append('text goes here');
append will add text to span tag at the end.
to replace entire text or html inside of span you can use .text()
or .html()
Use ax.yaxis.tick_right()
for example:
from matplotlib import pyplot as plt
f = plt.figure()
ax = f.add_subplot(111)
ax.yaxis.tick_right()
plt.plot([2,3,4,5])
plt.show()
Check chart.Boxplot from package PerformanceAnalytics
. It lets you define the symbol to use for the mean of the distribution.
By default, the chart.Boxplot(data)
command adds the mean as a red circle and the median as a black line.
Here is the output with sample data; MWE:
#install.packages(PerformanceAnalytics)
library(PerformanceAnalytics)
chart.Boxplot(cars$speed)
If you are going to use any DDOS provider like Akamai, they have a maximum limitation of 8k in the response header size. So essentially try to limit your response header size below 8k.
Crazy amount of complicated answers here. If you don't intend to process nodeJS files/database but just want to serve static html/css/js/images as your question suggest then simply install the pushstate-server module or similar;
Here's a "one liner" that will create and launch a mini site. Simply paste that entire block in your terminal in the appropriate directory.
mkdir mysite; \
cd mysite; \
npm install pushstate-server --save; \
mkdir app; \
touch app/index.html; \
echo '<h1>Hello World</h1>' > app/index.html; \
touch server.js; \
echo "var server = require('pushstate-server');server.start({ port: 3000, directory: './app' });" > server.js; \
node server.js
Open browser and go to http://localhost:3000. Done.
The server will use the app
dir as the root to serve files from. To add additional assets just place them inside that directory.
I do it like this:
<div class="lazyload" style="width: 1000px; height: 600px" data-src="%s">
<img class="spinner" src="spinner.gif"/>
</div>
and load with
$(window).load(function(){
$('.lazyload').each(function() {
var lazy = $(this);
var src = lazy.attr('data-src');
$('<img>').attr('src', src).load(function(){
lazy.find('img.spinner').remove();
lazy.css('background-image', 'url("'+src+'")');
});
});
});
After changing language newly created activities display with changed new language, but current activity and previously created activities which are in pause state are not updated.How to update activities ?
Pre API 11 (Honeycomb), the simplest way to make the existing activities to be displayed in new language is to restart it. In this way you don't bother to reload each resources by yourself.
private void restartActivity() {
Intent intent = getIntent();
finish();
startActivity(intent);
}
Register an OnSharedPreferenceChangeListener
, in its onShredPreferenceChanged()
, invoke restartActivity()
if language preference was changed. In my example, only the PreferenceActivity is restarted, but you should be able to restart other activities on activity resume by setting a flag.
Update (thanks @stackunderflow): As of API 11 (Honeycomb) you should use recreate()
instead of restartActivity()
.
public class PreferenceActivity extends android.preference.PreferenceActivity implements
OnSharedPreferenceChangeListener {
// ...
@Override
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
if (key.equals("pref_language")) {
((Application) getApplication()).setLocale();
restartActivity();
}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);
}
@Override
protected void onStop() {
super.onStop();
getPreferenceScreen().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(this);
}
}
I have a blog post on this topic with more detail, but it's in Chinese. The full source code is on github: PreferenceActivity.java
For bootstrap 4 we have new classes named with following notation
m - for classes that set margin
p - for classes that set padding
Specify Top, bottom,left, right, left & right, top & bottom using below letters
t - for classes that set margin-top (mt) or padding-top (pt)
b - for classes that set margin-bottom or padding-bottom
l - for classes that set margin-left or padding-left
r - for classes that set margin-right or padding-right
x - for classes that set both *-left and *-right
y - for classes that set both *-top and *-bottom
Specify size using following numbers
0 - for classes that eliminate the margin or padding by setting it to 0
1 - (by default) for classes that set the margin or padding to $spacer * .25
2 - (by default) for classes that set the margin or padding to $spacer * .5
3 - (by default) for classes that set the margin or padding to $spacer
4 - (by default) for classes that set the margin or padding to $spacer * 1.5
5 - (by default) for classes that set the margin or padding to $spacer * 3
Actual Code from bootstrap 4 css file
.mt-0 {
margin-top: 0 !important;
}
.ml-1 {
margin-left: ($spacer * .25) !important;
}
.px-2 {
padding-left: ($spacer * .5) !important;
padding-right: ($spacer * .5) !important;
}
.p-3 {
padding: $spacer !important;
}
Usage
So when you need some padding left just add any class from pl-0
to pl-5
based on your need
If you need margin on top just add any class from mt-0
to mt-5
based on your need
<div class="col-sm-6 mt-5"> this div will have margin top added </div>
<div class="col-sm-6 pl-5"> this div will have padding left added </div>
You have a JSON object that contains an Array. You need to access the array results
. Change your code to:
this.data = res.json().results
Create a form, use the POST method, submit the form - there's no need for an iframe. When the server page responds to the request, write a response header for the mime type of the file, and it will present a download dialog - I've done this a number of times.
You want content-type of application/download - just search for how to provide a download for whatever language you're using.
Copy this class and use custom Seek Bar :
public class MinMaxSeekBar extends SeekBar implements SeekBar.OnSeekBarChangeListener {
private OnMinMaxSeekBarChangeListener onMinMaxSeekBarChangeListener = null;
private int intMaxValue = 100;
private int intPrgress = 0;
private int minPrgress = 0;
public int getIntMaxValue() {
return intMaxValue;
}
public void setIntMaxValue(int intMaxValue) {
this.intMaxValue = intMaxValue;
int middle = getMiddle(intMaxValue, minPrgress);
super.setMax(middle);
}
public int getIntPrgress() {
return intPrgress;
}
public void setIntPrgress(int intPrgress) {
this.intPrgress = intPrgress;
}
public int getMinPrgress() {
return minPrgress;
}
public void setMinPrgress(int minPrgress) {
this.minPrgress = minPrgress;
int middle = getMiddle(intMaxValue, minPrgress);
super.setMax(middle);
}
private int getMiddle(int floatMaxValue, int minPrgress) {
int v = floatMaxValue - minPrgress;
return v;
}
public MinMaxSeekBar(Context context, AttributeSet attrs) {
super(context, attrs);
this.setOnSeekBarChangeListener(this);
}
public MinMaxSeekBar(Context context) {
super(context);
this.setOnSeekBarChangeListener(this);
}
@Override
public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
intPrgress = minPrgress + i;
onMinMaxSeekBarChangeListener.onMinMaxSeekProgressChanged(seekBar, intPrgress, b);
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
onMinMaxSeekBarChangeListener.onStartTrackingTouch(seekBar);
}
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
onMinMaxSeekBarChangeListener.onStopTrackingTouch(seekBar);
}
public static interface OnMinMaxSeekBarChangeListener {
public void onMinMaxSeekProgressChanged(SeekBar seekBar, int i, boolean b);
public void onStartTrackingTouch(SeekBar seekBar);
public void onStopTrackingTouch(SeekBar seekBar);
}
public void setOnIntegerSeekBarChangeListener(OnMinMaxSeekBarChangeListener floatListener) {
this.onMinMaxSeekBarChangeListener = floatListener;
}
}
This class contin method
public void setMin(int minPrgress)
for setting minimum value of Seek Bar This class contin methodpublic void setMax(int maxPrgress)
for setting maximum value of Seek Bar
