I agree with others who recommend using break
. The obvious consequential question is why would anyone recommend otherwise? Well... when you use break, you skip the rest of the code in the block, and the remaining iterations. Sometimes this causes bugs, for example:
a resource acquired at the top of the block may be released at the bottom (this is true even for blocks inside for
loops), but that release step may be accidentally skipped when a "premature" exit is caused by a break
statement (in "modern" C++, "RAII" is used to handle this in a reliable and exception-safe way: basically, object destructors free resources reliably no matter how a scope is exited)
someone may change the conditional test in the for
statement without noticing that there are other delocalised exit conditions
ndim's answer observes that some people may avoid break
s to maintain a relatively consistent loop run-time, but you were comparing break
against use of a boolean early-exit control variable where that doesn't hold
Every now and then people observing such bugs realise they can be prevented/mitigated by this "no breaks" rule... indeed, there's a whole related strategy for "safer" programming called "structured programming", where each function is supposed to have a single entry and exit point too (i.e. no goto, no early return). It may eliminate some bugs, but it doubtless introduces others. Why do they do it?
It should be a problem in your version of grep.
Your test cases are working correctly here on my machine:
$ echo "abc" | grep -io abc
abc
$ echo "ABC" | grep -io abc
ABC
And my version is:
$ grep --version
grep (GNU grep) 2.10
If it works fine on your local environment, probably your remote server's IP is being blocked by the server at the target URL you've set for cURL to use. You need to verify that your remote server is allowed to access the URL you've set for CURLOPT_URL.
I wouldn't want any public site that I developed to depend on any external site, and thus, I'd host jQuery myself.
Are you willing to have an outage on your site when the other (Google, jquery.com, etc.) goes down? Less dependencies is the key.
As already mentioned, tern.js is a new and promising project with plugins for Sublime Text, Vim and Emacs. I´ve been using TernJS for Sublime for a while and the suggestions I get are way better than the standard ones:
Tern scans all .js files in your project. You can get support for DOM, nodejs, jQuery, and more by adding "libs" in your .sublime-project file:
"ternjs": {
"exclude": ["wordpress/**", "node_modules/**"],
"libs": ["browser", "jquery"],
"plugins": {
"requirejs": {
"baseURL": "./js"
}
}
}
The first line tells the shell that if you execute the script directly (./run.sh; as opposed to /bin/sh run.sh), it should use that program (/bin/sh in this case) to interpret it.
You can also use it to pass arguments, commonly -e (exit on error), or use other programs (/bin/awk, /usr/bin/perl, etc).
Use following in your CSS
div {
-webkit-transform: rotate(90deg); /* Safari and Chrome */
-moz-transform: rotate(90deg); /* Firefox */
-ms-transform: rotate(90deg); /* IE 9 */
-o-transform: rotate(90deg); /* Opera */
transform: rotate(90deg);
}
Suffered from exact issue. Problem was because of NameValueSectionHandler in .config file. You should use AppSettingsSection instead:
<configuration>
<configSections>
<section name="DEV" type="System.Configuration.AppSettingsSection" />
<section name="TEST" type="System.Configuration.AppSettingsSection" />
</configSections>
<TEST>
<add key="key" value="value1" />
</TEST>
<DEV>
<add key="key" value="value2" />
</DEV>
</configuration>
then in C# code:
AppSettingsSection section = (AppSettingsSection)ConfigurationManager.GetSection("TEST");
btw NameValueSectionHandler is not supported any more in 2.0.
append
on an ndarray is ambiguous; to which axis do you want to append the data? Without knowing precisely what your data looks like, I can only provide an example using numpy.concatenate
that I hope will help:
import numpy as np
pixels = np.array([[3,3]])
pix = [4,4]
pixels = np.concatenate((pixels,[pix]),axis=0)
# [[3 3]
# [4 4]]
There are several ways. I personally use the following ones:
extracting single value:
String user_Id =
given().
when().
then().
extract().
path("user_id");
work with the entire response when you need more than one:
Response response =
given().
when().
then().
extract().
response();
String userId = response.path("user_id");
extract one using the JsonPath to get the right type:
long userId =
given().
when().
then().
extract().
jsonPath().getLong("user_id");
Last one is really useful when you want to match against the value and the type i.e.
assertThat(
when().
then().
extract().
jsonPath().getLong("user_id"), equalTo(USER_ID)
);
The rest-assured documentation is quite descriptive and full. There are many ways to achieve what you are asking: https://github.com/jayway/rest-assured/wiki/Usage
You can use this method to pick image from gallery. Only images will be displayed.
public void pickImage() {
Intent intent = new Intent(Intent.ACTION_PICK,
MediaStore.Images.Media.INTERNAL_CONTENT_URI);
intent.setType("image/*");
intent.putExtra("crop", "true");
intent.putExtra("scale", true);
intent.putExtra("outputX", 256);
intent.putExtra("outputY", 256);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("return-data", true);
startActivityForResult(intent, 1);
}
and override onActivityResult as
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != RESULT_OK) {
return;
}
if (requestCode == 1) {
final Bundle extras = data.getExtras();
if (extras != null) {
//Get image
Bitmap newProfilePic = extras.getParcelable("data");
}
}
}
There are two reasons to pass an argument by reference: (1) for performance (in which case you want to pass by const reference) and (2) because you need the ability to change the value of the argument inside the function.
I highly doubt that passing an unsigned long on modern architectures is slowing you down too much. So I'm assuming that you're intending to change the value of State
inside the method. The compiler is complaining because the constant 0
cannot be changed, as it's an rvalue ("non-lvalue" in the error message) and unchangeable (const
in the error message).
Simply put, you want a method that can change the argument passed, but by default you want to pass an argument that can't change.
To put it another way, non-const
references have to refer to actual variables. The default value in the function signature (0
) is not a real variable. You're running into the same problem as:
struct Foo {
virtual ULONG Write(ULONG& State, bool sequence = true);
};
Foo f;
ULONG s = 5;
f.Write(s); // perfectly OK, because s is a real variable
f.Write(0); // compiler error, 0 is not a real variable
// if the value of 0 were changed in the function,
// I would have no way to refer to the new value
If you don't actually intend to change State
inside the method you can simply change it to a const ULONG&
. But you're not going to get a big performance benefit from that, so I would recommend changing it to a non-reference ULONG
. I notice that you are already returning a ULONG
, and I have a sneaky suspicion that its value is the value of State
after any needed modifications. In which case I would simply declare the method as so:
// returns value of State
virtual ULONG Write(ULONG State = 0, bool sequence = true);
Of course, I'm not quite sure what you're writing or to where. But that's another question for another time.

This is a trick,
function OpenInNewTab(url) {
var win = window.open(url, '_blank');
win.focus();
}
In most cases, this should happen directly in the onclick handler for the link to prevent pop-up blockers, and the default "new window" behavior. You could do it this way, or by adding an event listener to your DOM object.
<div onclick="OpenInNewTab();">Something To Click On</div>
To answer the question more generaly how to redirect standard output to a variable ?
do the following :
from io import StringIO
import sys
result = StringIO()
sys.stdout = result
result_string = result.getvalue()
If you need to do that only in some function do the following :
old_stdout = sys.stdout
# your function containing the previous lines
my_function()
sys.stdout = old_stdout
Another way to get the same result:
date <- strptime(v,format="%Y%m%d")
If you have different storybord files and if you have outlet references with out outlets creation in your header files then you just remove the connections by right clicking on files owner.
Files owner->Right click->remove unwanted connection over there.
Go through this for clear explanation. What does this mean? "'NSUnknownKeyException', reason: … this class is not key value coding-compliant for the key X"
Let's say your primary key is an Integer and the object you save is "ticket", then you can get it like this. When you save the object, a Serializable id is always returned
Integer id = (Integer)session.save(ticket);
If you are using SQL Server try this:
SELECT * FROM MyTable
WHERE MyDate < DATEADD(month, -2, GETDATE())
Based on your update it would be:
SELECT * FROM FB WHERE Dte < DATEADD(month, -2, GETDATE())
This script outputs the Crontab to a file and also lists all users confirming those which have no crontab entry:
for user in $(cut -f1 -d: /etc/passwd); do
echo $user >> crontab.bak
echo "" >> crontab.bak
crontab -u $user -l >> crontab.bak 2>> > crontab.bak
done
After working on this on and off for a few days, here is the answer I would have wished to find, using pywin32 to keep it nice and self contained.
This is complete working code for one loop-based and one thread-based solution. It may work on both python 2 and 3, although I've only tested the latest version on 2.7 and Win7. The loop should be good for polling code, and the tread should work with more server-like code. It seems to work nicely with the waitress wsgi server that does not have a standard way to shut down gracefully.
I would also like to note that there seems to be loads of examples out there, like this that are almost useful, but in reality misleading, because they have cut and pasted other examples blindly. I could be wrong. but why create an event if you never wait for it?
That said I still feel I'm on somewhat shaky ground here, especially with regards to how clean the exit from the thread version is, but at least I believe there are nothing misleading here.
To run simply copy the code to a file and follow the instructions.
Use a simple flag to terminate thread. The important bit is that "thread done" prints.
For a more elaborate example exiting from an uncooperative server thread see my post about the waitress wsgi server.

Just wanted to contribute the three methods I've bounced back and forth with.
Method 1:
var record = ctx.Records.FirstOrDefault();
ctx.Records.Remove(record);
ctx.SaveChanges();
Method 2:
var record = ctx.Records.FirstOfDefault();
ctx.Entry(record).State = EntityState.Deleted;
ctx.SaveChanges();
ctx.Entry(record).State = EntityState.Detached;
One of the reasons why I prefer to go with Method 2 is because in the case of setting EF or EFCore to QueryTrackingBehavior.NoTracking
, it's safer to do.
Then there's Method 3:
var record = ctx.Records.FirstOrDefault();
var entry = ctx.Entry(record);
record.DeletedOn = DateTimeOffset.Now;
entry.State = EntityState.Modified;
ctx.SaveChanges();
entry.State = EntityState.Detached;
This utilizes a soft delete approach by setting the record's DeletedOn
property, and still being able to keep the record for future use, what ever that may be. Basically, putting it in the Recycle Bin.
Also, in regards to Method 3, instead of setting the entire record to being modified:
entry.State = EntityState.Modified;
You would also simply set only the column DeletedOn
as modified:
entry.Property(x => x.DeletedOn).IsModified = true;
Perhaps the default
template filter wasn't an option back in 2009...
<html>
<div>Hello {{name|default:"World"}}!</div>
</html>
(ls $source).LastWriteTime
("ls", "dir", or "gci" are the default aliases for Get-ChildItem.)
orphanRemoval
has nothing to do with ON DELETE CASCADE
.
orphanRemoval
is an entirely ORM-specific thing. It marks "child" entity to be removed when it's no longer referenced from the "parent" entity, e.g. when you remove the child entity from the corresponding collection of the parent entity.
ON DELETE CASCADE
is a database-specific thing, it deletes the "child" row in the database when the "parent" row is deleted.
Actually you can only style few CSS properties on :modified option elements.
color
does not work, background-color
either, but you can set a background-image
.
You can couple this with gradients to do the trick.
option:hover,_x000D_
option:focus,_x000D_
option:active,_x000D_
option:checked {_x000D_
background: linear-gradient(#5A2569, #5A2569);_x000D_
}
_x000D_
<select>_x000D_
<option>A</option>_x000D_
<option>B</option>_x000D_
<option>C</option>_x000D_
</select>
_x000D_
Works on gecko/webkit.
You could make use of the Javascript DOM API. In particular, look at the createElement() method.
You could create a re-usable function that will create an image like so...
function show_image(src, width, height, alt) {
var img = document.createElement("img");
img.src = src;
img.width = width;
img.height = height;
img.alt = alt;
// This next line will just add it to the <body> tag
document.body.appendChild(img);
}
Then you could use it like this...
<button onclick=
"show_image('http://google.com/images/logo.gif',
276,
110,
'Google Logo');">Add Google Logo</button>

If you’re using TortoiseSVN…
From your commit window in the “Changes Made” section you can select all the offending files, then right-click and select delete. Finish the commit and the files will be removed from the scheduled additions.
Use the random
module: http://docs.python.org/library/random.html
import random
random.sample(set([1, 2, 3, 4, 5, 6]), 2)
This samples the two values without replacement (so the two values are different).
I did everything above but had to do one more thing in IntelliJ:

I had to change every module's "language level"
With IOS9 you can use the layout anchor API.
The code would look like this:
childview.centerXAnchor.constraintEqualToAnchor(parentView.centerXAnchor).active = true
childview.centerYAnchor.constraintEqualToAnchor(parentView.centerYAnchor).active = true
The advantage of this over CGPointMake
or CGRect
is that with those methods you are setting the center of the view to a constant but with this technique you are setting a relationship between the two views that will hold forever, no matter how the parentview
changes.
Just be sure before you do this to do:
self.view.addSubview(parentView)
self.view.addSubView(chidview)
and to set the translatesAutoresizingMaskIntoConstraints
for each view to false.
This will prevent crashing and AutoLayout from interfering.
I was not satisfied with @Abhrabm answer because:
It was only preventing negative numbers from being entered from up/down arrows, whereas user can type negative number from keyboard.
Solution is to prevent with key code:
// Select your input element._x000D_
var number = document.getElementById('number');_x000D_
_x000D_
// Listen for input event on numInput._x000D_
number.onkeydown = function(e) {_x000D_
if(!((e.keyCode > 95 && e.keyCode < 106)_x000D_
|| (e.keyCode > 47 && e.keyCode < 58) _x000D_
|| e.keyCode == 8)) {_x000D_
return false;_x000D_
}_x000D_
}
_x000D_
<form action="" method="post">_x000D_
<input type="number" id="number" min="0" />_x000D_
<input type="submit" value="Click me!"/>_x000D_
</form>
_x000D_
Clarification provided by @Hugh Guiney:
What key codes are being checked:
So this script is preventing invalid key from being entered in input.
You can just add an onClick
handler to the div with the function (onClick
is React's own implementation of onClick
) and you can access the property within { }
curly braces, and your alert message will appear.
In case you wish to define static methods that can be called on the component class - you should use statics. Although:
"Methods defined within this block are static, meaning that you can run them before any component instances are created, and the methods do not have access to the props or state of your components. If you want to check the value of props in a static method, have the caller pass in the props as an argument to the static method." (source)
Some example code:
const Hello = React.createClass({
/*
The statics object allows you to define static methods that can be called on the component class. For example:
*/
statics: {
customMethod: function(foo) {
return foo === 'bar';
}
},
alertMessage: function() {
alert(this.props.name);
},
render: function () {
return (
<div onClick={this.alertMessage}>
Hello {this.props.name}
</div>
);
}
});
React.render(<Hello name={'aworld'} />, document.body);
Hope this helps you a bit, because i don't know if I understood your question correctly, so correct me if i interpreted it wrong:)
Also remember, the same idea applies to variables. You will come across terms like static, member, instance, class and so on when talking about variables the same as you would for methods/functions.
It seems the common term in the Obj-C community is ivar for instance variable, but I am not an Obj-C guy, yet.
EOF indicates "end of file". A newline (which is what happens when you press enter) isn't the end of a file, it's the end of a line, so a newline doesn't terminate this loop.
The code isn't wrong[*], it just doesn't do what you seem to expect. It reads to the end of the input, but you seem to want to read only to the end of a line.
The value of EOF is -1 because it has to be different from any return value from getchar
that is an actual character. So getchar
returns any character value as an unsigned char, converted to int, which will therefore be non-negative.
If you're typing at the terminal and you want to provoke an end-of-file, use CTRL-D (unix-style systems) or CTRL-Z (Windows). Then after all the input has been read, getchar()
will return EOF
, and hence getchar() != EOF
will be false, and the loop will terminate.
[*] well, it has undefined behavior if the input is more than LONG_MAX characters due to integer overflow, but we can probably forgive that in a simple example.
try the following code :
In your controller :
function myCtrl ($scope) {
$scope.units = [
{'id': 10, 'label': 'test1'},
{'id': 27, 'label': 'test2'},
{'id': 39, 'label': 'test3'},
];
$scope.data= $scope.units[0]; // Set by default the value "test1"
};
In your page :
<select ng-model="data" ng-options="opt as opt.label for opt in units ">
</select>
If you want to create a file and write and append data to it many times, then use the below code, it will create file if not exits and will append data if it exists.
SimpleDateFormat formatter = new SimpleDateFormat("yyyy_MM_dd");
Date now = new Date();
String fileName = formatter.format(now) + ".txt";//like 2016_01_12.txt
try
{
File root = new File(Environment.getExternalStorageDirectory()+File.separator+"Music_Folder", "Report Files");
//File root = new File(Environment.getExternalStorageDirectory(), "Notes");
if (!root.exists())
{
root.mkdirs();
}
File gpxfile = new File(root, fileName);
FileWriter writer = new FileWriter(gpxfile,true);
writer.append(sBody+"\n\n");
writer.flush();
writer.close();
Toast.makeText(this, "Data has been written to Report File", Toast.LENGTH_SHORT).show();
}
catch(IOException e)
{
e.printStackTrace();
}
If your static variables need to be set at runtime then a static {...}
block is very helpful.
For example, if you need to set the static member to a value which is stored in a config file or database.
Also useful when you want to add values to a static Map
member as you can't add these values in the initial member declaration.
The command below will search all the files recursively whose name matches the search pattern and will replace the string:
find /path/to/searchdir/ -name "serachpatter" -type f | xargs sed -i 's/stringone/StrIngTwo/g'
Also if you want to limit the depth of recursion you can put the limits as well:
find /path/to/searchdir/ -name "serachpatter" -type f -maxdepth 4 -mindepth 2 | xargs sed -i 's/stringone/StrIngTwo/g'
Hey i think The fastest way to handle that kind of operation is to memset() the memory.
Example-
memset(&myPage.pageArray[0][0], 0, sizeof(myPage.pageArray));
A similar C++ way would be to use std::fill
char *begin = myPage.pageArray[0][0];
char *end = begin + sizeof(myPage.pageArray);
std::fill(begin, end, 0);

Call Application.DoEvents()

One can also get "Skipping JaCoCo execution due to missing execution data file" error due to missing tests in project. For example when you fire up new project and have no *Test.java files at all.
Check out std::isdigit()
function.
If you just want the content as string
, then the simple solution is to use the ReadFile
function from the io/ioutil
package. This function returns a slice of bytes
which you can easily convert to a string
.
package main
import (
"fmt"
"io/ioutil"
)
func main() {
b, err := ioutil.ReadFile("file.txt") // just pass the file name
if err != nil {
fmt.Print(err)
}
fmt.Println(b) // print the content as 'bytes'
str := string(b) // convert content to a 'string'
fmt.Println(str) // print the content as a 'string'
}
To treat validation when a field is null in the database, you could add the following condition.
String name = (oRs.getString ("name_column"))! = Null? oRs.getString ("name_column"): "";
with this you can validate when a field is null and do not mark an exception.
Change
var trainindIdArray = traingIds.split(',');
to
var trainindIdArray = traingIds.replace("[","").replace("]","").split(',');
That will basically remove [
and ]
and then split the string
The documentation for css() says that setting the style property to the empty string will remove that property if it does not reside in a stylesheet:
Setting the value of a style property to an empty string — e.g.
$('#mydiv').css('color', '')
— removes that property from an element if it has already been directly applied, whether in the HTML style attribute, through jQuery's.css()
method, or through direct DOM manipulation of the style property. It does not, however, remove a style that has been applied with a CSS rule in a stylesheet or<style>
element.
Since your styles are inline, you can write:
$(selector).css("-moz-user-select", "");
For who has same issue on VS Professional 2019. I Installed Xamarin bundle and after that this IIS error starts. I have tried all solutions above without any luck. What I did to fix it is :
Outside of your technique, why not use the standard Java JarFile class to get the references you want? From there most of your problems should go away.
I think this works:
static void Main(string[] args)
{
String text = "One=1,Two=2,ThreeFour=34";
Console.WriteLine(betweenStrings(text, "One=", ",")); // 1
Console.WriteLine(betweenStrings(text, "Two=", ",")); // 2
Console.WriteLine(betweenStrings(text, "ThreeFour=", "")); // 34
Console.ReadKey();
}
public static String betweenStrings(String text, String start, String end)
{
int p1 = text.IndexOf(start) + start.Length;
int p2 = text.IndexOf(end, p1);
if (end == "") return (text.Substring(p1));
else return text.Substring(p1, p2 - p1);
}
A basic and very simple way of doing this without any code required would be to just provide an empty alt statement. The browser will then return the image as blank. It would look just like if the image isn't there.
Example:
<img class="img_gal" alt="" src="awesome.jpg">
Try it out to see! ;)
Use one of these as per your requirements.
Open the linked document in a new window or tab:

Open the linked document in the parent frame:
<a href="xyz.html" target="_parent"> Link </a>
Open the linked document in the full body of the window:

IMHO, if your FTP server is able to communicate with Fabric please us Fabric. It is far better than doing raw ftp
.
I have an FTP account from dotgeek.com
so I am not sure if this will work for other FTP accounts.
#!/usr/bin/python
from fabric.api import run, env, sudo, put
env.user = 'username'
env.hosts = ['ftp_host_name',] # such as ftp.google.com
def copy():
# assuming i have wong_8066.zip in the same directory as this script
put('wong_8066.zip', '/www/public/wong_8066.zip')
save the file as fabfile.py
and run fab copy
locally.
yeukhon@yeukhon-P5E-VM-DO:~$ fab copy2
[1.ai] Executing task 'copy2'
[1.ai] Login password:
[1.ai] put: wong_8066.zip -> /www/public/wong_8066.zip
Done.
Disconnecting from 1.ai... done.
Once again, if you don't want to input password all the time, just add
env.password = 'my_password'
The first one takes two parameters:
parseInt(string, radix)
The radix parameter is used to specify which numeral system to be used, for example, a radix of 16 (hexadecimal) indicates that the number in the string should be parsed from a hexadecimal number to a decimal number.
If the radix parameter is omitted, JavaScript assumes the following:
The other function you mentioned takes only one parameter:
Number(object)
The Number() function converts the object argument to a number that represents the object's value.
If the value cannot be converted to a legal number, NaN is returned.
It is a build target that is not a filename.
SELECT GETDATE() + (hours / 24.00000000000000000)
Adding to GETDATE() defaults to additional days, but it will also convert down to hours/seconds/milliseconds using decimal.
Nothing elegant but this could be another satisfactory answer.
merge(x = DF1, y = DF2, by = "Client", all.x=TRUE)[,c("Client","LO","CON")]
This will be useful especially when you don't need the keys that were used to join the tables in your results.
Simply call the ordinal()
method on an enum value, to retrieve its corresponding number. There's no need to declare an addition attribute with its value, each enumerated value gets its own number by default, assigned starting from zero, incrementing by one for each value in the same order they were declared.
You shouldn't depend on the int
value of an enum
, only on its actual value. Enums in Java are a different kind of monster and are not like enums in C, where you depend on their integer code.
Regarding the example you provided in the question, Font.PLAIN
works because that's just an integer constant of the Font class. If you absolutely need a (possibly changing) numeric code, then an enum
is not the right tool for the job, better stick to numeric constants.
just two commands save my life
1. This will list down all previous HEADs
git reflog
2. This will revert the HEAD to commit that you deleted.
git reset --hard <your deleted commit>
ex. git reset --hard b4b2c02
Try this:
=IF(NOT(ISERROR(MATCH(A3,worksheet2!A:A,0))),COUNTIF(worksheet2!A:A,A3),"No Match Found")

Here are some explanations why build_active_architecture
is set to NO.
Xcode now detects which devices you have connected and will set the active architecture accordingly. So if you plug a 2nd generation iPod Touch into your computer, Xcode should set the active architecture to armv6. Building your target with the above Debug configuration will now only build the armv6 binary to save time (unless you have a huge project you may not notice the difference but I guess the seconds add up over time).
When you create a Distribution configuration for publishing to the App Store, you should make sure this option is not set, so that Xcode will instead build the fat universal binary http://useyourloaf.com/blog/2010/04/21/xcode-build-active-architecture-only.html
The syntax to store the command output into a variable is var=$(command)
.
So you can directly do:
result=$(ls -l | grep -c "rahul.*patle")
And the variable $result
will contain the number of matches.
I found the solution to this problem here: http://www.hildeberto.com/2008/05/hibernate-and-jersey-conflict-on.html
One additional suggestion to be explicit. It seems best to go from specific to general down the stack of errors to get the desired error to be caught, so the specific ones don't get masked by the general one.
url='http://www.google.com/blahblah'
try:
r = requests.get(url,timeout=3)
r.raise_for_status()
except requests.exceptions.HTTPError as errh:
print ("Http Error:",errh)
except requests.exceptions.ConnectionError as errc:
print ("Error Connecting:",errc)
except requests.exceptions.Timeout as errt:
print ("Timeout Error:",errt)
except requests.exceptions.RequestException as err:
print ("OOps: Something Else",err)
Http Error: 404 Client Error: Not Found for url: http://www.google.com/blahblah
vs
url='http://www.google.com/blahblah'
try:
r = requests.get(url,timeout=3)
r.raise_for_status()
except requests.exceptions.RequestException as err:
print ("OOps: Something Else",err)
except requests.exceptions.HTTPError as errh:
print ("Http Error:",errh)
except requests.exceptions.ConnectionError as errc:
print ("Error Connecting:",errc)
except requests.exceptions.Timeout as errt:
print ("Timeout Error:",errt)
OOps: Something Else 404 Client Error: Not Found for url: http://www.google.com/blahblah
A long-term solution: userscript
You can use a userscript like Tampermonkey (if you are using Chrome or Edge-Chromium, here is the extension)
Then create a script and paste this in it:
// ==UserScript==
// @name Google docs
// @include https://*docs.google.*/document/*
// @grant GM_addStyle
// ==/UserScript==
GM_addStyle ( `
.kix-page-compact::before {
border-top: none;
}
` );
A temporary fix: developer console
You can use the developper console. In Chrome:
1. open your document on google docs
2. click in the url field and press ctrl+shift+I (or right click just above help
and select "view page source)
Then modify the css (cf the steps on the printscreen below) :
1. once the console is loaded press ctrl+F and paste this : kix-page kix-page-compact
2. click on the div just below the one that is highlighted in yellow
3. in the right part, paste this in the filter
box : .kix-page-compact::before
4. click on 1px dotted #aaa
next to border-top
and replace it by none
Now you can do in swift the following thing which allows you to regain a little bit of the objective-c if nil else
if textfieldDate.text?.isEmpty ?? true {
}
I found something interesting in SQL server when checking if inner joins are faster than left joins.
If you dont include the items of the left joined table, in the select statement, the left join will be faster than the same query with inner join.
If you do include the left joined table in the select statement, the inner join with the same query was equal or faster than the left join.
Are all the modifications to file.py
in branch2
in their own commits, separate from modifications to other files? If so, you can simply cherry-pick
the changes over:
git checkout branch1
git cherry-pick <commit-with-changes-to-file.py>
Otherwise, merge
does not operate over individual paths...you might as well just create a git diff
patch of file.py
changes from branch2
and git apply
them to branch1
:
git checkout branch2
git diff <base-commit-before-changes-to-file.py> -- file.py > my.patch
git checkout branch1
git apply my.patch
git diff
for unstaged changes.
git diff --cached
for staged changes.
git diff HEAD
for both staged and unstaged changes.
Here a working fiddle: http://jsfiddle.net/sjh36otu/
function add_number() {
var first_number = parseInt(document.getElementById("Text1").value);
var second_number = parseInt(document.getElementById("Text2").value);
var result = first_number + second_number;
document.getElementById("txtresult").value = result;
}
System.Data.SqlClient
is the .NET Framework Data Provider for SQL Server. ie .NET library for SQL Server.
I don't know where providerName=SqlServer
comes from. Could you be getting this confused with the provider keyword in your connection string? (I know I was :) )
In the web.config you should have the System.Data.SqlClient
as the value of the providerName attribute. It is the .NET Framework Data Provider you are using.
<connectionStrings>
<add
name="LocalSqlServer"
connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true"
providerName="System.Data.SqlClient"
/>
</connectionStrings>

In short, the answer is no. Once you show an alert
, confirm
, or prompt
the script no longer has control until the user returns control by clicking one of the buttons.
To do what you want, you will want to use DOM elements like a div
and show, then hide it after a specified time. If you need to be modal (takes over the page, allowing no further action) you will have to do additional work.
You could of course use one of the many "dialog" libraries out there. One that comes to mind right away is the jQuery UI Dialog widget
the problem is blade, try this
<i class="fa" v-bind:class="['{{content['cravings']}}' ? 'fa-checkbox-marked' : 'fa-checkbox-blank-outline']"></i>
#multiplying each element in the list and adding it into an empty list
original = [1, 2, 3]
results = []
for num in original:
results.append(num*2)# multiply each iterative number by 2 and add it to the empty list.
print(results)
@Jagdish Barabari's answer gave me the clue I needed to resolve this. Turns out there were two versions of postgresql installed while only one was running. Purging all postgresql files and reinstalling the latest version resolved this issue for me.
This is relatively simple if you use pylab (included with matplotlib) instead of matplotlib directly. Start off with a list of filenames and legend names, like [ ('name of file 1', 'label 1'), ('name of file 2', 'label 2'), ...]. Then you can use something like the following:
import pylab
datalist = [ ( pylab.loadtxt(filename), label ) for filename, label in list_of_files ]
for data, label in datalist:
pylab.plot( data[:,0], data[:,1], label=label )
pylab.legend()
pylab.title("Title of Plot")
pylab.xlabel("X Axis Label")
pylab.ylabel("Y Axis Label")
You also might want to add something like fmt='o' to the plot command, in order to change from a line to points. By default, matplotlib with pylab plots onto the same figure without clearing it, so you can just run the plot command multiple times.
While this is an old post, it is something that helped me solve the issue. So to keep others stumbling upon this to find a solution using the current Angular2 stack (2.0.0-rc.4 at this time), I downgraded my jQuery version to 2.2.4, added the bootstrap.js distributed under node_modules/bootstrap/dist/js to my InjectableDependencies (using gulp, and defining this in the project.config.ts file) and everything continues to work just fine.
The answers above and on this question either didn't work for me with Selenium 3.14 and Firefox 68.9 on Linux, or are unnecessarily complex. I needed to use a WPAD configuration, sometimes behind a proxy (on a VPN), and sometimes not. After studying the code a bit, I came up with:
from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile
proxy = Proxy({'proxyAutoconfigUrl': 'http://wpad/wpad.dat'})
profile = FirefoxProfile()
profile.set_proxy(proxy)
driver = webdriver.Firefox(firefox_profile=profile)
The Proxy initialization sets proxyType to ProxyType.PAC (autoconfiguration from a URL) as a side-effect.
It also worked with Firefox's autodetect, using:
from selenium.webdriver.common.proxy import ProxyType
proxy = Proxy({'proxyType': ProxyType.AUTODETECT})
But I don't think this would work with both internal URLs (not proxied) and external (proxied) the way WPAD does. Similar proxy settings should work for manual configuration as well. The possible proxy settings can be seen in the code here.
Note that directly passing the Proxy object as proxy=proxy
to the driver does NOT work--it's accepted but ignored (there should be a deprecation warning, but in my case I think Behave is swallowing it).
Double perValue = 96.57;
int roundVal= (int) Math.round(perValue);
Solved my purpose.
You could also use matrix transposition:
(a.T / row_sums).T
One more to thing to think about when daemonizing in python:
If your are using python logging and you want to continue using it after daemonizing, make sure to call close()
on the handlers (particularly the file handlers).
If you don't do this the handler can still think it has files open, and your messages will simply disappear - in other words make sure the logger knows its files are closed!
This assumes when you daemonise you are closing ALL the open file descriptors indiscriminatingly - instead you could try closing all but the log files (but it's usually simpler to close all then reopen the ones you want).
If you don't want to dock label in whole available area, just set SizeChanged event instead of TextChanged. Changing each letter will change the width property of label as well as its text when autosize property set to True. So, by the way you can use any formula to keep label centered in form.
private void lblReport_SizeChanged(object sender, EventArgs e)
{
lblReport.Left = (this.ClientSize.Width - lblReport.Size.Width) / 2;
}
I know this question is 10 years old but there is no C# solution and this took me hours to figure out. I'm using the .NET driver and System.Linq
to return a list of the keys.
var map = new BsonJavaScript("function() { for (var key in this) { emit(key, null); } }");
var reduce = new BsonJavaScript("function(key, stuff) { return null; }");
var options = new MapReduceOptions<BsonDocument, BsonDocument>();
var result = await collection.MapReduceAsync(map, reduce, options);
var list = result.ToEnumerable().Select(item => item["_id"].ToString());
Try Microsoft's NEWT, it worked perfect for me. It supplies customized latency, packet drop techniques and more :)

Update 1:

select * from tempdb.sys.columns where object_id =
object_id('tempdb..#mytemptable');
You need to prevent the default behaviour. You can either use e.preventDefault()
or return false;
In this case, the best thing is, you can use return false;
here:
<form onsubmit="completeAndRedirect(); return false;">
To complement @tyczj answer:
Generic Adapter Pseido code:
public abstract class GenericRecycleAdapter<T, K extends RecyclerView.ViewHolder> extends RecyclerView.Adapter{
private List<T> mList;
//default implementation code
public abstract int getLayout();
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext())
.inflate(getLayout(), parent, false);
return getCustomHolder(v);
}
public Holders.TextImageHolder getCustomHolder(View v) {
return new Holders.TextImageHolder(v){
@Override
public void onClick(View v) {
onItem(mList.get(this.getAdapterPosition()));
}
};
}
abstract void onItem(T t);
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
onSet(mList.get(position), (K) holder);
}
public abstract void onSet(T item, K holder);
}
ViewHolder:
public class Holders {
public static class TextImageHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
public TextView text;
public TextImageHolder(View itemView) {
super(itemView);
text = (TextView) itemView.findViewById(R.id.text);
text.setOnClickListener(this);
}
@Override
public void onClick(View v) {
}
}
}
Adapter usage:
public class CategoriesAdapter extends GenericRecycleAdapter<Category, Holders.TextImageHolder> {
public CategoriesAdapter(List<Category> list, Context context) {
super(list, context);
}
@Override
void onItem(Category category) {
}
@Override

return R.layout.categories_row;
}
@Override
public void onSet(Category item, Holders.TextImageHolder holder) {
}
}
Use this
$("input[name='nameOfYourRadioButton']").attr("checked", false);
You have to look how this is called:
someObject.equals(someOtherObj);
This invokes the equals
method on the instance of someObject
. Now, inside that method:
public boolean equals(Object obj) { if (obj == this) { //is someObject equal to obj, which in this case is someOtherObj? return true;//If so, these are the same objects, and return true }
You can see that this
is referring to the instance of the object that equals is called on. Note that equals()
is non-static, and so must be called only on objects that have been instantiated.
Note that ==
is only checking to see if there is referential equality; that is, the reference of this
and obj
are pointing to the same place in memory. Such references are naturally equal:
Object a = new Object(); Object b = a; //sets the reference to b to point to the same place as a Object c = a; //same with c b.equals(c);//true, because everything is pointing to the same place
Further note that equals()
is generally used to also determine value equality. Thus, even if the object references are pointing to different places, it will check the internals to determine if those objects are the same:
FancyNumber a = new FancyNumber(2);//Internally, I set a field to 2 FancyNumber b = new FancyNumber(2);//Internally, I set a field to 2 a.equals(b);//true, because we define two FancyNumber objects to be equal if their internal field is set to the same thing.

if <local> is already forwarded
adb forward --remove <local> - remove a specific forward socket connection
adb forward --remove-all - remove all forward socket connections
adb reverse --list - list all reverse socket connections from device
adb reverse <remote> <local> - reverse socket connections
reverse specs are one of:
tcp:<port>
localabstract:<unix domain socket name>
localreserved:<unix domain socket name>

If no -f option is supplied then the data is written
to "backup.ab" in the current directory.
(-apk|-noapk enable/disable backup of the .apks themselves
in the archive; the default is noapk.)
(-obb|-noobb enable/disable backup of any installed apk expansion
(aka .obb) files associated with each application; the default
is noobb.)
(-shared|-noshared enable/disable backup of the device's
shared storage / SD card contents; the default is noshared.)
(-all means to back up all installed applications)
(-system|-nosystem toggles whether -all automatically includes
system applications; the default is to include system apps)
(<packages...> is the list of applications to be backed up. If
the -all or -shared flags are passed, then the package
list is optional. Applications explicitly given on the

You can listen to the dragend
event, and if the map is dragged outside the allowed bounds, move it back inside. You can define your allowed bounds in a LatLngBounds
object and then use the contains()
method to check if the new lat/lng center is within the bounds.
You can also limit the zoom level very easily.

Screenshot from the above example. The user will not be able to drag further south or far east in this case:
Note that in the Java implementation, the number of bits to shift is mod'd by the size of the source.
For example:
(long) 4 >> 65
equals 2. You might expect shifting the bits to the right 65 times would zero everything out, but it's actually the equivalent of:
(long) 4 >> (65 % 64)
This is true for <<, >>, and >>>. I have not tried it out in other languages.
>>> x = 'lipsum'
>>> x.replace(x[:3], '')
'sum'
You can include git repository to composer.json like this:
"repositories": [
{
"type": "package",
"package": {
"name": "example-package-name", //give package name to anything, must be unique
"version": "1.0",
"source": {
"url": "https://github.com/example-package-name.git", //git url
"type": "git",
"reference": "master" //git branch-name
}
}
}],
"require" : {
"example-package-name": "1.0"
}
Stop reinventing the wheel. Use https://github.com/medialize/URI.js/
var uri = new URI("http://example.org:80/foo/hello.html");
// get host
uri.host(); // returns string "example.org:80"
// set host
uri.host("example.org:80");
var input = document.getElementById("customx");
if (input && input.value) {
alert(1);
}
else {
alert (0);
}
The typical pattern would be as follows, but you need to actually define how the ordering should be applied (since a table is, by definition, an unordered bag of rows):
SELECT t.A, t.B, t.C, number = ROW_NUMBER() OVER (ORDER BY t.A)
FROM dbo.tableZ AS t
ORDER BY t.A;
Not sure what the variables in your question are supposed to represent (they don't match).
Another approach to this would put a span element with a display:block style inside the p element each time you need the content to break. It would only be useful when your p content is static.
<p>this is a not-dynamic text and I want to put<span style="display:block">the following words in the next line</span>and these other words in a third one</p>
It would output:
This is a not-dynamic text and I want to put
the following words in the next line
and these others in a third one
This allows you to change your text line-breaks in different viewports without JS.
Use sysdate-1 to subtract one day from system date.
select sysdate, sysdate -1 from dual;
Output:
SYSDATE SYSDATE-1
-------- ---------
22-10-13 21-10-13
This can also be fixed by installing a node package manually.
npm install npm -g
The process of doing that will setup all the required directories.
there are some mistakes in your code - the first: you havn't closed you p
-tag:
<a href="http//www.google.com"><p style="text-align:center">Search</p></a>
next: p
stands for 'paragraph' and is a block-element (so it's causing a line-break). what you wanted to use there is a span
, wich is just an inline-element for formatting:
<a href="http//www.google.com"><span style="text-align:center">Search</span></a>
but if you just want to add a style to your link, why don't you set the style for that link directly:
<a href="http//www.google.com" style="text-align:center">Search</a>
in the end, this would at least be correct html, but still not exactly what you want, because text-align:center
centers the text in that element, so you would have to set that for the element that contains this links (this piece of html isn't posted, so i can't correct you, but i hope you understand) - to show this, i'll use a simple div
:
<div style="text-align:center">
<a href="http//www.google.com">Search</a>
<!-- more links here -->
</div>
EDIT: some more additions to your question:
p
is not a 'function', but you're right, this is causing the problem (because it's a block-element)I've had issues with using SELECT last_insert_rowid()
in a multithreaded environment. If another thread inserts into another table that has an autoinc, last_insert_rowid will return the autoinc value from the new table.
Here's where they state that in the doco:
If a separate thread performs a new INSERT on the same database connection while the sqlite3_last_insert_rowid() function is running and thus changes the last insert rowid, then the value returned by sqlite3_last_insert_rowid() is unpredictable and might not equal either the old or the new last insert rowid.
That's from sqlite.org doco
Since you didn't specify what server-side scripting method you're using, I'll give you an example that works for Python, using CherryPy (although it may be useful for other contexts, too):
<button type="submit" name="register">Create a new account</button>
<button type="submit" name="login">Log into your account</button>
Rather than using the value to determine which button was pressed, you can use the name (with the <button>
tag instead of <input>
). That way, if your buttons happen to have the same text, it won't cause problems. The names of all form items, including buttons, are sent as part of the URL. In CherryPy, each of those is an argument for a method that does the server-side code. So, if your method just has **kwargs
for its parameter list (instead of tediously typing out every single name of each form item) then you can check to see which button was pressed like this:
if "register" in kwargs:
pass #Do the register code
elif "login" in kwargs:
pass #Do the login code
If it is in the same class it is fine to trust the method.
It is very common to do this. It is good practice to check null values in constructor's and method's arguments to make sure that nobody is passing null values into them (if it is not allowed). Then if you implement your methods in a way that they never set the "start" graph to null, don't check for nulls there.
It is also good practice to implement unit tests for your methods and make sure that they are correctly implemented, so you can trust them.

As of CMake 3.1+ the developers strongly discourage users from using file(GLOB
or file(GLOB_RECURSE
to collect lists of source files.
Note: We do not recommend using GLOB to collect a list of source files from your source tree. If no CMakeLists.txt file changes when a source is added or removed then the generated build system cannot know when to ask CMake to regenerate. The CONFIGURE_DEPENDS flag may not work reliably on all generators, or if a new generator is added in the future that cannot support it, projects using it will be stuck. Even if CONFIGURE_DEPENDS works reliably, there is still a cost to perform the check on every rebuild.
See the documentation here.
There are two goods answers ([1], [2]) here on SO detailing the reasons to manually list source files.
It is possible. E.g. with file(GLOB
:
cmake_minimum_required(VERSION 2.8)
file(GLOB helloworld_SRC
"*.h"
"*.cpp"
)
add_executable(helloworld ${helloworld_SRC})
Note that this requires manual re-running of cmake
if a source file is added or removed, since the generated build system does not know when to ask CMake to regenerate, and doing it at every build would increase the build time.
As of CMake 3.12, you can pass the CONFIGURE_DEPENDS
flag to file(GLOB
to automatically check and reset the file lists any time the build is invoked. You would write:
cmake_minimum_required(VERSION 3.12)
file(GLOB helloworld_SRC CONFIGURE_DEPENDS "*.h" "*.cpp")
This at least lets you avoid manually re-running CMake every time a file is added.
col-md-offset-4 does not work if you manually apply margin to the same element. For example
In the above code, offset will not be applied. Instead a margin of 0 auto will be applied
Check the Namespace.
You might assign System.Web.Webpages.Html.SelectListItem in the Controller, instead of System.Web.Mvc.SelectListItem.
If you look in your installation's bin directory you will see catalina.sh or .bat scripts. If you look in these you will see that they run a setenv.sh or setenv.bat script respectively, if it exists, to set environment variables. The relevant environment variables are described in the comments at the top of catalina.sh/bat. To use them create, for example, a file $CATALINA_HOME/bin/setenv.sh with contents
export JAVA_OPTS="-server -Xmx512m"
For Windows you will need, in setenv.bat, something like
set JAVA_OPTS=-server -Xmx768m
Original answer here
After you run startup.bat
, you can easily confirm the correct settings have been applied provided you have turned @echo
on somewhere in your catatlina.bat
file (a good place could be immediately after echo Using CLASSPATH: "%CLASSPATH%"
):
$this->validate($request,[
'input_field_name'=>'digits_between:2,5',
]);
Try this it will be work
This is a feature, not a bug.
See http://docs.python.org/howto/unicode.html, specifically the 'unicode type' section.
You simply need to use the asset
helper function in Laravel. (The url
helper can also be used in this manner)
<img src="{{ asset('images/arrow.gif') }}" />
For the absolute path, you use public_path
instead.
<p>Absolute path: {{ public_path('images/arrow.gif') }}</p>
If you are providing the URL to a public image from a controller (backend) you can use asset
as well, or secure_asset
if you want HTTPS. eg:
$url = asset('images/arrow.gif'); # http://example.com/assets/images/arrow.gif
$secure_url = secure_asset('images/arrow.gif'); # https://example.com/assets/images/arrow.gif
return $secure_url;
Lastly, if you want to go directly to the image on a given route you can redirect to it:
return \Redirect::to($secure_url);
More Laravel helper functions can be found here
I would try this first
select * from employee where month(current_date)-3 = month(joining_date)
Well, your favorite text editor does not realize that \xc3\xa1
are supposed to be character literals, but it interprets them as text. That's why you get the double backslashes in the last line -- it's now a real backslash + xc3
, etc. in your file.
If you want to read and write encoded files in Python, best use the codecs module.
Pasting text between the terminal and applications is difficult, because you don't know which program will interpret your text using which encoding. You could try the following:
>>> s = file("f1").read()
>>> print unicode(s, "Latin-1")
Capitán
Then paste this string into your editor and make sure that it stores it using Latin-1. Under the assumption that the clipboard does not garble the string, the round trip should work.
Use this for slivers AppBar
SliverAppBar (

@K Scott Piel wrote a great answer here, but I want to add one important point.
Note that the stdout
stream is usually line-buffered, so to ensure the output is actually printed and not just left sitting in the buffer waiting to be written you must flush the buffer by either ending your printf
statement with a \n
Ex:
printf("hello world\n");
or
printf("hello world");
printf("\n");
or similar, OR you must call fflush(stdout);
after your printf
call.
Ex:
printf("hello world");
fflush(stdout);
Read more here: Why does printf not flush after the call unless a newline is in the format string?
I will recommend to use an alternative method using seaborn
which more powerful tool for data plotting. You can use seaborn scatterplot
and define colum 3 as hue
and size
.
Working code:
import pandas as pd
import seaborn as sns
import numpy as np
#creating sample data
sample_data={'col_name_1':np.random.rand(20),
'col_name_2': np.random.rand(20),'col_name_3': np.arange(20)*100}
df= pd.DataFrame(sample_data)
sns.scatterplot(x="col_name_1", y="col_name_2", data=df, hue="col_name_3",size="col_name_3")
Judging from the example information above, I think this entire article is based on a bugged behavior in Tomcat 6.0.29 and earlier. See https://issues.apache.org/bugzilla/show_bug.cgi?id=50026. Upgrade to Tomcat 6.0.30 and the behavior between (Tomcat|Jetty) should merge.
what about having the image be something selected by the user? Use a input:file tag and then after they select the image, show it on the clientside webpage? That is doable for most things. Right now i am trying to get it working for IE, but as with all microsoft products, it is a cluster fork().

Yes.
It is a good practice since an element can be a part of different groups, and you may want specific elements to be a part of more than one group. The element can hold an infinite number of classes in HTML5, while in HTML4 you are limited by a specific length.
The following example will show you the use of multiple classes.
The first class makes the text color
red.
The second class makes the background-color
blue.
See how the DOM Element with multiple classes will behave, it will wear both CSS statements at the same time.
Result: multiple CSS statements in different classes will stack up.
You can read more about CSS Specificity.
.class1 {
color:red;
}
.class2 {
background-color:blue;
}
<div class="class1">text 1</div>
<div class="class2">text 2</div>
<div class="class1 class2">text 3</div>
downloadJsonFile(data, filename: string){
// Creating a blob object from non-blob data using the Blob constructor
const blob = new Blob([JSON.stringify(data)], { type: 'application/json' });
const url = URL.createObjectURL(blob);
// Create a new anchor element
const a = document.createElement('a');
a.href = url;
a.download = filename || 'download';
a.click();
a.remove();
}
You can easily auto download file with using Blob and transfer it in first param downloadJsonFile. filename is name of file you wanna set.
While this works:
<%-- <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ht_tv1.Default" %> --%>
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Blank._Default" %>
This won't.
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" <%--Inherits="ht_tv1.Default"--%> Inherits="Blank._Default" %>
So you can't comment out part of something which is what I want to do 99.9995% of the time.
Also try to update your browser because Angular need latest browser. check: https://angular.io/guide/browser-support
I fixed console.log issue after updating latest browser.
Python has a built-in datatype for an unordered collection of (hashable) things, called a set
. If you convert both lists to sets, the comparison will be unordered.
set(x) == set(y)
EDIT: @mdwhatcott points out that you want to check for duplicates. set
ignores these, so you need a similar data structure that also keeps track of the number of items in each list. This is called a multiset; the best approximation in the standard library is a collections.Counter
:
>>> import collections
>>> compare = lambda x, y: collections.Counter(x) == collections.Counter(y)
>>>

You have to use DENSE_RANK rather than RANK. The only difference is that it doesn't leave gaps. You also shouldn't partition by contender_num, otherwise you're ranking each contender in a separate group, so each is 1st-ranked in their segregated groups!
SELECT contendernum,totals, DENSE_RANK() OVER (ORDER BY totals desc) AS xRank FROM
(
SELECT ContenderNum ,SUM(Criteria1+Criteria2+Criteria3+Criteria4) AS totals
FROM dbo.Cat1GroupImpersonation
GROUP BY ContenderNum
) AS a
order by contendernum
A hint for using StackOverflow, please post DDL and sample data so people can help you using less of their own time!
create table Cat1GroupImpersonation (
contendernum int,
criteria1 int,
criteria2 int,
criteria3 int,
criteria4 int);
insert Cat1GroupImpersonation select
1,196,0,0,0 union all select
2,181,0,0,0 union all select
3,192,0,0,0 union all select
4,181,0,0,0 union all select
5,179,0,0,0;
Try this simple solution:
In your activity implement onBackPressed
@Override
public void onBackPressed() {
if (getSupportFragmentManager().getBackStackEntryCount() > 1) {
getSupportFragmentManager().popBackStack();
} else {
finish();
}
}
This will work if you want to pop the top fragment on each back press. Note:- While adding fragment to activity always do add the transaction to back stack for this to work
First of all, install the prerequisite libraries:
sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev
Then install rbenv, which is used to install Ruby:
cd
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL
git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL
rbenv install 2.3.1
rbenv global 2.3.1
ruby -v
Then (optional) tell Rubygems to not install local documentation:
echo "gem: --no-ri --no-rdoc" > ~/.gemrc

Example 2 on w3schools shows what you are trying to achieve.
<?php header("Content-type:application/pdf"); // It will be called downloaded.pdf header("Content-Disposition:attachment;filename='downloaded.pdf'"); // The PDF source is in original.pdf readfile("original.pdf"); ?>
Also remember that,
It is important to notice that header() must be called before any actual output is sent (In PHP 4 and later, you can use output buffering to solve this problem)
First remove super.onBackPressed();
from onbackPressed()
method than and below code:
@Override
public void onBackPressed() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Are you sure you want to exit?")
.setCancelable(false)
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
MyActivity.this.finish();
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
}
Just to add to @Anshul Singh Suryan's answer:
When we split the dataframe to just get the last column:
If we split like:
y = df.iloc[:,-1:] - y
remains a dataframe
However, if we split like
y = df.iloc[:,-1] - y
becomes a Series
.
This is a notable difference that I've found in the two approaches. If you don't care about the resultant type, you can use either of the two. Otherwise you need to take care of the above findings.
This is applicable for any number of rows you want to extract and not just the last row.
For example, if you want last n
number of rows of a dataframe, where n is any integer less than or equal to the number of columns present in the dataframe, then you can easily do the following:
y = df.iloc[:,n:]
Replace n
by the number of columns you want. Same is true for rows as well.
If keys are nested:
d1 = { 'key1': { 'nkey1': 'x1' }, 'key2': { 'nkey2': 'y1' } }
d2 = { 'key1': { 'nkey1': 'x2' }, 'key2': { 'nkey2': 'y2' } }
ds = [d1, d2]
d = {}
for k in d1.keys():
for k2 in d1[k].keys():
d.setdefault(k, {})
d[k].setdefault(k2, [])
d[k][k2] = tuple(d[k][k2] for d in ds)
yields:
{'key1': {'nkey1': ('x1', 'x2')}, 'key2': {'nkey2': ('y1', 'y2')}}
You need nunique
:
df = df.groupby('domain')['ID'].nunique()
print (df)
domain
'facebook.com' 1
'google.com' 1
'twitter.com' 2
'vk.com' 3
Name: ID, dtype: int64
If you need to strip
'
characters:
df = df.ID.groupby([df.domain.str.strip("'")]).nunique()
print (df)
domain
facebook.com 1
google.com 1
twitter.com 2
vk.com 3
Name: ID, dtype: int64
Or as Jon Clements commented:
df.groupby(df.domain.str.strip("'"))['ID'].nunique()
You can retain the column name like this:
df = df.groupby(by='domain', as_index=False).agg({'ID': pd.Series.nunique})
print(df)
domain ID
0 fb 1
1 ggl 1
2 twitter 2
3 vk 3
The difference is that nunique()
returns a Series and agg()
returns a DataFrame.
In Python 3 the dict.values()
method returns a dictionary view object, not a list like it does in Python 2. Dictionary views have a length, can be iterated, and support membership testing, but don't support indexing.
To make your code work in both versions, you could use either of these:
{names[i]:value for i,value in enumerate(d.values())}
or
values = list(d.values())
{name:values[i] for i,name in enumerate(names)}
By far the simplest, fastest way to do the same thing in either version would be:
dict(zip(names, d.values()))
Note however, that all of these methods will give you results that will vary depending on the actual contents of d
. To overcome that, you may be able use an OrderedDict instead, which remembers the order that keys were first inserted into it, so you can count on the order of what is returned by the values()
method.

// Compile the regex String into a Pattern
Pattern p = Pattern.compile(regexStr);
// Create a matcher with the input String
Matcher m = p.matcher(inputStr);
// If we find a match
if (m.find()) {
// Get the String from the first capture group
String someDigits = m.group(1);

This isn't semantic but I just use the existing a
element, set a background image, then create multiple variations for @2x resolution, smaller screen sizes, etc.
Then, you can use the .text-hide
class to get some text on the page the ol' fashion way. Simple and effective though not proper use of an image.
Here's a link to the helper class for text-replacement:
I hope that I am understing your question correctly, but you can do this very quickly with Linq. I'm assuming that universally you will always have an Id property. Just create an interface to ensure this.
If how you identify an object to be the same changes from class to class, I would recommend passing in a delegate that returns true if the two objects have the same persistent id.
Here is how to do it in Linq:
List<Employee> listA = new List<Employee>();
List<Employee> listB = new List<Employee>();
listA.Add(new Employee() { Id = 1, Name = "Bill" });
listA.Add(new Employee() { Id = 2, Name = "Ted" });
listB.Add(new Employee() { Id = 1, Name = "Bill Sr." });
listB.Add(new Employee() { Id = 3, Name = "Jim" });
var identicalQuery = from employeeA in listA
join employeeB in listB on employeeA.Id equals employeeB.Id
select new { EmployeeA = employeeA, EmployeeB = employeeB };
foreach (var queryResult in identicalQuery)
{
Console.WriteLine(queryResult.EmployeeA.Name);
Console.WriteLine(queryResult.EmployeeB.Name);
}
I don't know what happened with my project but it referenced the wrong path to the DLL. Nuget installed it properly and it was indeed on my file system along with the other packages but just referenced incorrectly.
The packages
folder exists two directories up from my project and it was only going up one by starting the path with ..\packages\
. I changed the path to start with ..\..\packages\
and it fixed my problem.
I don't know if this can be related to the OP's post but I was missing the [HttpGet] annotation and that was what was causing the error, as stated by @dinesh_ravva methods are assumed to be HttpPost by default.
I like the Aptana Browser Preview windo for this.
You can get it from their update site: http://download.aptana.org/tools/studio/plugin/update/studio/
After you install the Aptana plugin, open an Aptana project and there should be an option under help to install aptana features. under other you will find a Firefox/XUL browser. There may be a more direct way to install the XUL plugin, but the above procedure works.
In SQL Server 2016 you can use DROP IF EXISTS:

GO
DROP TABLE IF EXISTS t
RABL is probably the nicest solution to this that I've seen if you're looking for a cleaner alternative to ERb syntax. json_builder and argonaut, which are other solutions, both seem somewhat outdated and won't work with Rails 3.1 without some patching.

I would recommend wxpython. It's very easy to use and the documentation is pretty good.
I doubt my answer is in time to help you but others might find it helpful. I experienced a similar issue with a jQuery Ajax Post script that i created.
It turned out that i had a typo in the href attribute of the A tag that i was using to fire the post. I had typed href="javacsript:;" (reversing the 's' and the 'c' ).. this caused the script to try to refresh the page while the post was attempting to fire. corrected the typo and it worked perfectly fine for me.

You can use SHOW
:
SHOW max_connections;
This returns the currently effective setting. Be aware that it can differ from the setting in postgresql.conf
as there are a multiple ways to set run-time parameters in PostgreSQL. To reset the "original" setting from postgresql.conf
in your current session:
RESET max_connections;
However, not applicable to this particular setting. The manual:
This parameter can only be set at server start.
To see all settings:
SHOW ALL;
There is also pg_settings
:
The view
pg_settings
provides access to run-time parameters of the server. It is essentially an alternative interface to theSHOW
andSET
commands. It also provides access to some facts about each parameter that are not directly available fromSHOW
, such as minimum and maximum values.
For your original request:
SELECT *
FROM pg_settings
WHERE name = 'max_connections';
Finally, there is current_setting()
, which can be nested in DML statements:
SELECT current_setting('max_connections');

With jQuery (and without FormData API) you can use something like this:
function readFile(file){
var loader = new FileReader();
var def = $.Deferred(), promise = def.promise();
//--- provide classic deferred interface
loader.onload = function (e) { def.resolve(e.target.result); };
loader.onprogress = loader.onloadstart = function (e) { def.notify(e); };
loader.onerror = loader.onabort = function (e) { def.reject(e); };
promise.abort = function () { return loader.abort.apply(loader, arguments); };
loader.readAsBinaryString(file);
return promise;
}
function upload(url, data){
var def = $.Deferred(), promise = def.promise();
var mul = buildMultipart(data);
var req = $.ajax({
url: url,
data: mul.data,
processData: false,
type: "post",
async: true,
contentType: "multipart/form-data; boundary="+mul.bound,
xhr: function() {
var xhr = jQuery.ajaxSettings.xhr();
if (xhr.upload) {
xhr.upload.addEventListener('progress', function(event) {
var percent = 0;
var position = event.loaded || event.position; /*event.position is deprecated*/
var total = event.total;
if (event.lengthComputable) {
percent = Math.ceil(position / total * 100);
def.notify(percent);
}
}, false);
}
return xhr;
}
});
req.done(function(){ def.resolve.apply(def, arguments); })
.fail(function(){ def.reject.apply(def, arguments); });
promise.abort = function(){ return req.abort.apply(req, arguments); }
return promise;
}
var buildMultipart = function(data){
var key, crunks = [], bound = false;
while (!bound) {
bound = $.md5 ? $.md5(new Date().valueOf()) : (new Date().valueOf());
for (key in data) if (~data[key].indexOf(bound)) { bound = false; continue; }
}
for (var key = 0, l = data.length; key < l; key++){
if (typeof(data[key].value) !== "string") {
crunks.push("--"+bound+"\r\n"+
"Content-Disposition: form-data; name=\""+data[key].name+"\"; filename=\""+data[key].value[1]+"\"\r\n"+
"Content-Type: application/octet-stream\r\n"+
"Content-Transfer-Encoding: binary\r\n\r\n"+
data[key].value[0]);
}else{
crunks.push("--"+bound+"\r\n"+
"Content-Disposition: form-data; name=\""+data[key].name+"\"\r\n\r\n"+
data[key].value);
}
}
return {
bound: bound,
data: crunks.join("\r\n")+"\r\n--"+bound+"--"
};
};
//----------
//---------- On submit form:
var form = $("form");
var $file = form.find("#file");
readFile($file[0].files[0]).done(function(fileData){
var formData = form.find(":input:not('#file')").serializeArray();
formData.file = [fileData, $file[0].files[0].name];
upload(form.attr("action"), formData).done(function(){ alert("successfully uploaded!"); });
});
With FormData API you just have to add all fields of your form to FormData object and send it via $.ajax({ url: url, data: formData, processData: false, contentType: false, type:"POST"})
You can access column name specifically like this too if you don't want to loop through all columns:
table.Columns[1].ColumnName

<button onclick="myVar += 1;alert('myVar now equals ' + myVar)">Increment!!</button>
Here is a good choice for gradients for both platforms iOS and Android:
https://github.com/react-native-community/react-native-linear-gradient
There are others approaches like expo, however react-native-linear-gradient have worked better for me.
<LinearGradient colors={['#4c669f', '#3b5998', '#192f6a']} style={styles.linearGradient}>
<Text style={styles.buttonText}>
Sign in with Facebook
</Text>
</LinearGradient>
// Later on in your styles..
var styles = StyleSheet.create({
linearGradient: {
flex: 1,
paddingLeft: 15,
paddingRight: 15,
borderRadius: 5
},
buttonText: {
fontSize: 18,
fontFamily: 'Gill Sans',
textAlign: 'center',
margin: 10,
color: '#ffffff',
backgroundColor: 'transparent',
},
});
Here is another alternative for adding leading to 0s to strings such as CUSIPs which can sometimes look like a number and which many applications such as Excel will corrupt and remove the leading 0s or convert them to scientific notation.
When I tried the answer provided by @metasequoia the vector returned had leading spaces and not 0
s. This was the same problem mentioned by @user1816679 -- and removing the quotes around the 0
or changing from %d
to %s
did not make a difference either. FYI, I am using RStudio Server running on an Ubuntu Server. This little two-step solution worked for me:
gsub(pattern = " ", replacement = "0", x = sprintf(fmt = "%09s", ids[,CUSIP]))
using the %>%
pipe function from the magrittr
package it could look like this:
sprintf(fmt = "%09s", ids[,CUSIP]) %>% gsub(pattern = " ", replacement = "0", x = .)
I'd prefer a one-function solution, but it works.
It is a little difficult to answer your specific question without a full, reproducible example. However something like this should work:
#Turn your 'treatment' column into a character vector
data$Treatment <- as.character(data$Treatment)
#Then turn it back into a factor with the levels in the correct order
data$Treatment <- factor(data$Treatment, levels=unique(data$Treatment))
In this example, the order of the factor will be the same as in the data.csv
file.
If you prefer a different order, you can order them by hand:
data$Treatment <- factor(data$Treatment, levels=c("Y", "X", "Z"))
However this is dangerous if you have a lot of levels: if you get any of them wrong, that will cause problems.
You can also define these chars as list of string. Then you can check if the characters is valid for accepted characters with list.Contains(x) method.
If you want to initialize an object based on an interface you can initialize it empty with following statement.
myObj: IMyObject = {} as IMyObject;
DROP EVENT IF EXISTS xxxEVENTxxx;
CREATE EVENT xxxEVENTxxx
ON SCHEDULE
EVERY 1 DAY
STARTS (TIMESTAMP(CURRENT_DATE) + INTERVAL 1 DAY + INTERVAL 1 HOUR)

I was having a situation in ASP.NET 4.0 where my session would be reset on every page request (and my SESSION_START code would run on each page request). This didn't happen to every user for every session, but it usually happened, and when it did, it would happen on each page request.
My web.config sessionState tag had the same setting as the one mentioned above.
cookieless="false"
When I changed it to the following...
cookieless="UseCookies"
... the problem seemed to go away. Apparently true|false were old choices from ASP.NET 1. Starting in ASP.Net 2.0, the enumerated choices started being available. I guess these options were deprecated. The "false" value has never presented a problem in the past - I've only noticed in on ASP.NET 4.0. I don't know if something has changed in 4.0 that no longer supports it correctly.
Also, I just found this out not long ago. Since the problem was intermittent before, I suppose I could still encounter it, but so far it's working with this new setting.
Another simple way:
$("#selectedID")[0].selectedIndex = -1
Make sure you follow the language definition for JSON. In your second example, the section:
"labs":[{
""
}]
Is invalid since an object must be composed of zero or more key-value pairs "a" : "b"
, where "b"
may be any valid value. Some parsers may automatically interpret { "" }
to be { "" : null }
, but this is not a clearly defined case.
Also, you are using a nested array of objects [{}]
quite a bit. I would only do this if:
Typing q
starts macro recording, and the recording stops when the user hits q
again.
As Joey Adams mentioned, to disable recording, add the following line to .vimrc
in your home directory:
map q <Nop>
I had this warning possibly because of calling setState
from an effect hook (This is discussed in these 3 issues linked together).
Anyway, upgrading the react version removed the warning.
This is simple but the developer gets confused due to multiple views having the same attributes in different configurations/namespaces.
In the case of the TextInputLayout we have every time a different view and with params either with TextInputEditText or directly to TextInputLayout.
I was using all the above fixes: But I found that I was using
app:textColorHint="@color/textcolor_black"
actually i should be using
android:textColorHint="@color/textcolor_black"
As an attribute of TextinputLayout
textcolor_black.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="@color/black_txt" android:state_enabled="true" />
<item android:color="@color/black_txt" android:state_selected="true" />
<item android:color="@color/txtColorGray" android:state_selected="false" />
<item android:color="@color/txtColorGray" android:state_enabled="false" />
</selector>
You got the first part right:
Yes mapStateToProps
has the Store state as an argument/param (provided by react-redux::connect
) and its used to link the component with certain part of the store state.
By linking I mean the object returned by mapStateToProps
will be provided at construction time as props and any subsequent change will be available through componentWillReceiveProps
.
If you know the Observer design pattern it's exactly that or small variation of it.
An example would help make things clearer:
import React, {
Component,
} from 'react-native';
class ItemsContainer extends Component {
constructor(props) {
super(props);
this.state = {
items: props.items, //provided by connect@mapStateToProps
filteredItems: this.filterItems(props.items, props.filters),
};
}
componentWillReceiveProps(nextProps) {
this.setState({
filteredItems: this.filterItems(this.state.items, nextProps.filters),
});
}
filterItems = (items, filters) => { /* return filtered list */ }
render() {
return (
<View>
// display the filtered items
</View>
);
}
}
module.exports = connect(
//mapStateToProps,
(state) => ({
items: state.App.Items.List,
filters: state.App.Items.Filters,
//the State.App & state.App.Items.List/Filters are reducers used as an example.
})
// mapDispatchToProps, that's another subject
)(ItemsContainer);
There can be another react component called itemsFilters
that handle the display and persisting the filter state into Redux Store state, the Demo component is "listening" or "subscribed" to Redux Store state filters so whenever filters store state changes (with the help of filtersComponent
) react-redux detect that there was a change and notify or "publish" all the listening/subscribed components by sending the changes to their componentWillReceiveProps
which in this example will trigger a refilter of the items and refresh the display due to the fact that react state has changed.
Let me know if the example is confusing or not clear enough to provide a better explanation.
As for: This means that the state as consumed by your target component can have a wildly different structure from the state as it is stored on your store.
I didn't get the question, but just know that the react state (this.setState
) is totally different from the Redux Store state!
The react state is used to handle the redraw and behavior of the react component. The react state is contained to the component exclusively.
The Redux Store state is a combination of Redux reducers states, each is responsible of managing a small portion app logic. Those reducers attributes can be accessed with the help of react-redux::connect@mapStateToProps
by any component! Which make the Redux store state accessible app wide while component state is exclusive to itself.

Once this is done, you can open a CMD where your scripts are saved, or manually navigate through the CMD.
To run the script enter:
C: \ User \ X \ MyScripts> python ScriptName.py
$('.close').click(function() {
//Code to be executed when close is clicked
$('#result').html('yes,result');
});
function countOcurrences(arr){
return arr.reduce((aggregator, value, index, array) => {
if(!aggregator[value]){
return aggregator = {...aggregator, [value]: 1};
}else{
return aggregator = {...aggregator, [value]:++aggregator[value]};
}
}, {})
}
Another way to set placeholder icon & set padding to TextField.
let userIcon = UIImage(named: "ImageName")
setPaddingWithImage(image: userIcon, textField: txtUsername)
func setPaddingWithImage(image: UIImage, textField: UITextField){
let imageView = UIImageView(image: image)
imageView.contentMode = .scaleAspectFit
let view = UIView(frame: CGRect(x: 0, y: 0, width: 60, height: 50))
imageView.frame = CGRect(x: 13.0, y: 13.0, width: 24.0, height: 24.0)
//For Setting extra padding other than Icon.
let seperatorView = UIView(frame: CGRect(x: 50, y: 0, width: 10, height: 50))
seperatorview.backgroundColor = UIColor(red: 80/255, green: 89/255, blue: 94/255, alpha: 1)
view.addSubview(seperatorView)
textField.leftViewMode = .always
view.addSubview(imageView)
view.backgroundColor = .darkGray
textField.leftViewMode = UITextFieldViewMode.always
textField.leftView = view
}
Use
System.getProperty("java.class.path")
see http://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html
You can also split it into it's elements easily
String classpath = System.getProperty("java.class.path");
String[] classpathEntries = classpath.split(File.pathSeparator);
The following worked great for me:
echo "show processlist" | mysql | grep -v ^Id | awk '{print $1}' | xargs -i echo "KILL {}; | mysql"
"How do I for example read a 3 bit integer value starting at the second bit?"
int number = // whatever;
uint8_t val; // uint8_t is the smallest data type capable of holding 3 bits
val = (number & (1 << 2 | 1 << 3 | 1 << 4)) >> 2;
(I assumed that "second bit" is bit #2, i. e. the third bit really.)
<form target="_blank" [....]
will submit the form in a new tab... I am not sure if is this what you are looking for, please explain better...
You can do this in this way:
use this jQuery plugin for pre & post paste events:
$.fn.pasteEvents = function( delay ) {
if (delay == undefined) delay = 20;
return $(this).each(function() {
var $el = $(this);
$el.on("paste", function() {
$el.trigger("prepaste");
setTimeout(function() { $el.trigger("postpaste"); }, delay);
});
});
};
Now you can use this plugin;:
$('#txt').on("prepaste", function() {
$(this).find("*").each(function(){
var tmp=new Date.getTime();
$(this).data("uid",tmp);
});
}).pasteEvents();
$('#txt').on("postpaste", function() {
$(this).find("*").each(function(){
if(!$(this).data("uid")){
$(this).removeClass();
$(this).removeAttr("style id");
}
});
}).pasteEvents();
Explaination
First set a uid for all existing elements as data attribute.
Then compare all nodes POST PASTE event. So by comparing you can identify the newly inserted one because they will have a uid, then just remove style/class/id attribute from newly created elements, so that you can keep your older formatting.

Apply classes to your TDs, apply the appropriate widths (remember to leave one of them without a width so it assumes the remainder of the width), then apply the appropriate styles. Copy and paste the code below into an editor and view in a browser to see it function.

<p>Hi,</p>
<p>I want to wrap a text that is added to the TD. I have tried with style="word-wrap: break-word;" width="15%". But the wrap is not happening. Is it mandatory to give 100% width ? But I have got other controls to display so only 15% width available.</p>
<p>Need help.</p>
<p>TIA.</p>
</td>
<td class="rightcolumn">This is the right column, it has no width so it assumes the remainder from the 15% and 20% assumed by the others. By default, if a width is applied and no white-space declarations are made, your text will automatically wrap.</td>
