If you prefer to use Query Builder instead of Eloquent here is the solutions
$result = DB::table('user')->where('name',=,'Jhon')->get();
First Solution
$array = (array) $result;
Second Solution
$array = get_object_vars($result);
Third Solution
$array = json_decode(json_encode($result), true);
hope it may help
@page margin:0mm now works in Firefox 19.0a2 (2012-12-07).
The function fromJSON() in RJSONIO, rjson and jsonlite don't return a simple 2D data.frame for complex nested json objects.
To overcome this you can use tidyjson. It takes in a json and always returns a data.frame. It is currently not availble in CRAN, you can get it here: https://github.com/sailthru/tidyjson
Update: tidyjson is now available in cran, you can install it directly using install.packages("tidyjson")
ps aux | grep processname | cut -d' ' -f7 | xargs kill -9 $
I suspect the error is caused by this:
foreach (KeyValuePair<int, int> kvp in rankings)
rankings is a dictionary, which is IEnumerable. By using it in a foreach loop, you're specifying that you want each KeyValuePair from the dictionary in a deferred manner. That is, the next KeyValuePair is not returned until your loop iterates again.
But you're modifying the dictionary inside your loop:
rankings[kvp.Key] = rankings[kvp.Key] + 4;
which isn't allowed...so you get the exception.
You could simply do this
foreach (KeyValuePair<int, int> kvp in rankings.ToArray())
Quite and simple without any "having to specify the first element". CSS is more powerful than most think (e.g. the first-child:before
is great!). But this is by far the cleanest and most proper way to do this, at least in my opinion it is.
#navigation ul
{
margin: 0;
padding: 0;
}
#navigation ul li
{
list-style-type: none;
display: inline;
}
#navigation li:not(:first-child):before {
content: " | ";
}
Now just use a simple unordered list in HTML and it'll populate it for you. HTML should look like this:
<div id="navigation">
<ul>
<li><a href="#">Home</a></li>
<li><a href="#">About Us</a></li>
<li><a href="#">Support</a></li>
</ul>
</div><!-- navigation -->
The result will be just like this:
HOME | ABOUT US | SUPPORT
Now you can indefinitely expand and never have to worry about order, changing links, or your first entry. It's all automated and works great!
thanks to Jim Petkus that did gave me a wonderful answer . but i was trying to solve my own script not to changing it to another plugin . My main focus was not using an independent plugin and do what i wanted just by using the jquery core !
and guess what i did find the problem .
var title = $("em").attr("title");
$("div").text(title);
this is what i add to my script and the blew codes to my html part :
<td> <em title=\"$weight\">$weight</em></td>
and found each row $weight value
thanks again to Jim Petkus
This one liner replaces all the ^M characters:

You can call this from inside Perl or directly on your Unix prompt.
Also, when you uninstall the package, the first item listed is the directory to the executable.
Since sizeWithFont is deprecated I use this one instead.
this one get label specific attributes.
-(CGFloat)heightForLabel:(UILabel *)label withText:(NSString *)text{
NSAttributedString *attributedText = [[NSAttributedString alloc] initWithString:text attributes:@{NSFontAttributeName:label.font}];
CGRect rect = [attributedText boundingRectWithSize:(CGSize){label.frame.size.width, CGFLOAT_MAX}
options:NSStringDrawingUsesLineFragmentOrigin
context:nil];
return ceil(rect.size.height);
}
Here's an easier way of doing this (source: here):
import matplotlib.pyplot as plt
from numpy.random import rand
fig, ax = plt.subplots()
for color in ['red', 'green', 'blue']:
n = 750
x, y = rand(2, n)
scale = 200.0 * rand(n)
ax.scatter(x, y, c=color, s=scale, label=color,
alpha=0.3, edgecolors='none')
ax.legend()
ax.grid(True)
plt.show()
And you'll get this:

Multi-threading with javascript is clearly possible using webworkers bring by HTML5.
Main difference between webworkers and a standard multi-threading environment is memory resources are not shared with the main thread, a reference to an object is not visible from one thread to another. Threads communicate by exchanging messages, it is therefore possible to implement a synchronzization and concurrent method call algorithm following an event-driven design pattern.
Many frameworks exists allowing to structure programmation between threads, among them OODK-JS, an OOP js framework supporting concurrent programming https://github.com/GOMServices/oodk-js-oop-for-js
I followed Andrew's answer, but I also had to follow https://stackoverflow.com/a/35833548 and set the x and y axes separately due to a bug in my version of ggplot (v2.1.0).
Instead of
theme(axis.line = element_line(color = 'black'))
I used
theme(axis.line.x = element_line(color="black", size = 2),
axis.line.y = element_line(color="black", size = 2))
Use below XML configuration to configure logs into two or more files:
<log4net>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="logs\log.txt" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline" />
</layout>
</appender>
<appender name="RollingLogFileAppender2" type="log4net.Appender.RollingFileAppender">
<file value="logs\log1.txt" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline" />
</layout>
</appender>
<root>
<level value="All" />
<appender-ref ref="RollingLogFileAppender" />
</root>
<logger additivity="false" name="RollingLogFileAppender2">
<level value="All"/>
<appender-ref ref="RollingLogFileAppender2" />
</logger>
</log4net>
Above XML configuration logs into two different files. To get specific instance of logger programmatically:
ILog logger = log4net.LogManager.GetLogger ("RollingLogFileAppender2");
You can append two or more appender elements inside log4net root element for logging into multiples files.
More info about above XML configuration structure or which appender is best for your application, read details from below links:

One possible explanation is a database trigger that fires for each DROP TABLE
statement. To find the trigger, query the _TRIGGERS
dictionary views:
select * from all_triggers
where trigger_type in ('AFTER EVENT', 'BEFORE EVENT')
disable any suspicious trigger with
alter trigger <trigger_name> disable;
and try re-running your DROP TABLE
statement
@Cmyker, great solution for chart.js v2
One little enhancement: It makes sense to check for the appropriate canvas id, see the modified snippet below. Otherwise the text (i.e. 75%) is also rendered in middle of other chart types within the page.
Chart.pluginService.register({
beforeDraw: function(chart) {
if (chart.canvas.id === 'doghnutChart') {
let width = chart.chart.width,
height = chart.chart.outerRadius * 2,
ctx = chart.chart.ctx;
rewardImg.width = 40;
rewardImg.height = 40;
let imageX = Math.round((width - rewardImg.width) / 2),
imageY = (height - rewardImg.height ) / 2;
ctx.drawImage(rewardImg, imageX, imageY, 40, 40);
ctx.save();
}
}
});
Since a legend (see: http://www.chartjs.org/docs/latest/configuration/legend.html) magnifies the chart height, the value for height should be obtained by the radius.
In my case I wanted to have responsive table height instead of fixed height in pixels as the other answers are showing. To do that I used percentage of visible height property and overflow on div containing the table:
&__table-container {
height: 70vh;
overflow: scroll;
}
This way the table will expand along with the window being resized.
Let's say you have 2 csv
files like these:
csv1.csv:
id,name
1,Armin
2,Sven
csv2.csv:
id,place,year
1,Reykjavik,2017
2,Amsterdam,2018
3,Berlin,2019
and you want the result to be like this csv3.csv:
id,name,place,year
1,Armin,Reykjavik,2017
2,Sven,Amsterdam,2018
3,,Berlin,2019
Then you can use the following snippet to do that:
import csv
import pandas as pd
# the file names
f1 = "csv1.csv"
f2 = "csv2.csv"
out_f = "csv3.csv"
# read the files
df1 = pd.read_csv(f1)
df2 = pd.read_csv(f2)
# get the keys
keys1 = list(df1)
keys2 = list(df2)
# merge both files
for idx, row in df2.iterrows():
data = df1[df1['id'] == row['id']]
# if row with such id does not exist, add the whole row
if data.empty:
next_idx = len(df1)
for key in keys2:
df1.at[next_idx, key] = df2.at[idx, key]
# if row with such id exists, add only the missing keys with their values
else:
i = int(data.index[0])
for key in keys2:
if key not in keys1:
df1.at[i, key] = df2.at[idx, key]
# save the merged files
df1.to_csv(out_f, index=False, encoding='utf-8', quotechar="", quoting=csv.QUOTE_NONE)
With the help of a loop you can achieve the same result for multiple files as it is in your case (200 csv files).
var date = new Date();_x000D_
date.setDate(date.getDate() + 7);_x000D_
_x000D_
console.log(date);
_x000D_
And yes, this also works if date.getDate() + 7
is greater than the last day of the month. See MDN for more information.
As mentioned in multiple answers above you can import the cURL in POSTMAN directly. But if URL is authorized (or is not working for some reason) ill suggest you can manually add all the data points as JSON in your postman body. take the API URL from the cURL.
for the Authorization part- just add an Authorization key and base 64 encoded string as value.
example:
curl -u rzp_test_26ccbdbfe0e84b:69b2e24411e384f91213f22a \ https://api.razorpay.com/v1/orders -X POST \ --data "amount=50000" \ --data "currency=INR" \ --data "receipt=Receipt #20" \ --data "payment_capture=1" https://api.razorpay.com/v1/orders
{
"amount": "5000",
"currency": "INR",
"receipt": "Receipt #20",
"payment_capture": "1"
}
Headers:
Authorization:Basic cnpwX3Rlc3RfWEk5QW5TU0N3RlhjZ0Y6dURjVThLZ3JiQVVnZ3JNS***U056V25J
where "cnpwX3Rlc3RfWEk5QW5TU0N3RlhjZ0Y6dURjVThLZ3JiQVVnZ3JNS***U056V25J" is the encoded form of "rzp_test_26ccbdbfe0e84b:69b2e24411e384f91213f22a"`
small tip: for encoding, you can easily go to your chrome console (right-click => inspect) and type :
btoa("string you want to encode")
( or use postman basic authorization)
I don't know when exactly the tokens expire, but they do, otherwise there wouldn't be an option to give offline permissions.
Anyway, sometimes requiring the user to give offline permissions is an overkill. Depending on your needs, maybe it's enough that the token remains valid as long as the website is opened in the user's browser. For this there may be a simpler solution - relogging the user in periodically using an iframe: facebook auto re-login from cookie php

As you said your table contains 260,000 records...and IN Predicate
contains six values. Now, each record is being search 260,000 times for each value in IN Predicate

Instead of a List<UserRole>
, you can let your Model contain a SelectList<UserRole>
. Also add a property SelectedUserRoleId
to store... well... the selected UserRole's Id value.
Fill up the SelectList, then in your View use:
@Html.DropDownListFor(x => x.SelectedUserRoleId, x.UserRole)
and you should be fine.

A common use of JSON is to read data from a web server, and display the data in a web page.
This chapter will teach you how to exchange JSON data between the client and a PHP server.
PHP has some built-in functions to handle JSON.
Objects in PHP can be converted into JSON by using the PHP function json_encode():
<?php_x000D_
$myObj->name = "John";_x000D_
$myObj->age = 30;_x000D_
$myObj->city = "New York";_x000D_
_x000D_
$myJSON = json_encode($myObj);_x000D_
_x000D_
echo $myJSON;_x000D_
?>
_x000D_
function getURLParameter(name) {
return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search) || [null, ''])[1].replace(/\+/g, '%20')) || null;
}
So you can use:
myvar = getURLParameter('myvar');
I would suggest instead of creating a new table, you just use a view that combines the two tables, this way if any of the data in table 1 or table 2 changes, you don't need to update the third table:
CREATE VIEW dbo.YourView
AS
SELECT t1.Name, t1.Age, t1.Sex, t1.City, t1.ID, t2.Number
FROM Table1 t1
INNER JOIN Table2 t2
ON t1.ID = t2.ID;
If you could have records in one table, and not in the other, then you would need to use a full join:
CREATE VIEW dbo.YourView
AS
SELECT t1.Name, t1.Age, t1.Sex, t1.City, ID = ISNULL(t1.ID, t2.ID), t2.Number
FROM Table1 t1
FULL JOIN Table2 t2
ON t1.ID = t2.ID;
If you know all records will be in table 1 and only some in table 2, then you should use a LEFT JOIN
:
CREATE VIEW dbo.YourView
AS
SELECT t1.Name, t1.Age, t1.Sex, t1.City, t1.ID, t2.Number
FROM Table1 t1
LEFT JOIN Table2 t2
ON t1.ID = t2.ID;
If you know all records will be in table 2 and only some in table 2 then you could use a RIGHT JOIN
CREATE VIEW dbo.YourView
AS
SELECT t1.Name, t1.Age, t1.Sex, t1.City, t2.ID, t2.Number
FROM Table1 t1
RIGHT JOIN Table2 t2
ON t1.ID = t2.ID;
Or just reverse the order of the tables and use a LEFT JOIN (I find this more logical than a right join but it is personal preference):
CREATE VIEW dbo.YourView
AS
SELECT t1.Name, t1.Age, t1.Sex, t1.City, t2.ID, t2.Number
FROM Table2 t2
LEFT JOIN Table1 t1
ON t1.ID = t2.ID;

I found a simple combo of QoP and speckledcarp's answer using React Hooks and resizing features, with slightly less lines of code:
const [width, setWidth] = useState(window.innerWidth);
const [height, setHeight] = useState(window.innerHeight);
const updateDimensions = () => {
setWidth(window.innerWidth);
setHeight(window.innerHeight);
}
useEffect(() => {
window.addEventListener("resize", updateDimensions);
return () => window.removeEventListener("resize", updateDimensions);
}, []);
Oh yeah make sure that the resize
event is in double quotes, not single. That one got me for a bit ;)
Andy E. gave a good answer.
I would add, if you feel to select all the childs in some special selector (this need happened to me recently), you can apply the method "getElementsByTagName()" on any DOM object you want.
For an example, I needed to just parse "visual" part of the web page, so I just made this
var visualDomElts = document.body.getElementsByTagName('*');
This will never take in consideration the head part.
NUMERIC(3,2)
means: 3 digits in total, 2 after the decimal point. So you only have a single decimal before the decimal point.
Try NUMERIC(5,2)
- three before, two after the decimal point.
In your CSS file:
.TableHeader { width: 100px; }
This will set all of the td
tags below each header to 100px. You can also add a width definition (in the markup) to each individual th
tag, but the above solution would be easier.
Using dialog methods:
$('.selectorUsedToCreateTheDialog').dialog('option', 'title', 'My New title');
Or directly, hacky though:
$("span.ui-dialog-title").text('My New Title');
For future reference, you can skip google with jQuery. The jQuery API will answer your questions most of the time. In this case, the Dialog API page. For the main library: http://api.jquery.com
The pros and cons are pretty much identical.It depends on whether you want this or not.
Be careful, if MySQL timezone differs from your system time (for instance PHP), comparing the time or printing to the user will involve some tinkering.

Matplotlib makes great publication-quality graphics, but is not very well optimized for speed. There are a variety of python plotting packages that are designed with speed in mind:
There is a companion tool called Oracle Data Modeler that you could take a look at. There are online demos available at the site that will get you started. It used to be an added cost item, but I noticed that once again it's free.
From the Data Modeler overview page:
SQL Developer Data Modeler is a free data modeling and design tool, proving a full spectrum of data and database modeling tools and utilities, including modeling for Entity Relationship Diagrams (ERD), Relational (database design), Data Type and Multi-dimensional modeling, with forward and reverse engineering and DDL code generation. The Data Modeler imports from and exports to a variety of sources and targets, provides a variety of formatting options and validates the models through a predefined set of design rules.
This has nothing to do with jQuery, just JavaScript in general.
To create an array in JavaScript:
var a = [];
Or:
var a = ['value1', 'value2', 'value3'];
To append values on the end of existing array:
a.push('value4');
To create a new array, you should really use []
instead of new Array()
for the following reasons:
new Array(1, 2)
is equivalent to [1, 2]
, but new Array(1)
is not equivalent to [1]
. Rather the latter is closer to [undefined]
, since a single integer argument to the Array
constructor indicates the desired array length.Array
, just like any other built-in JavaScript class, is not a keyword. Therefore, someone could easily define Array
in your code to do something other than construct an array.Python 3:
import urllib.request
wp = urllib.request.urlopen("http://google.com")
pw = wp.read()
print(pw)
Python 2:
import urllib
import sys
wp = urllib.urlopen("http://google.com")
for line in wp:
sys.stdout.write(line)

Since you have mysql on your local computer, you do not need to bother with the IP address of the machine. Just use localhost:
mysql -u user -p
or
mysql -hlocalhost -u user -p
If you cannot login with this, you must find out what usernames (user@host) exist in the MySQL Server locallly. Here is what you do:
Step 01) Startup mysql so that no passwords are require no passwords and denies TCP/IP connections
service mysql restart --skip-grant-tables --skip-networking
Keep in mind that standard SQL for adding users, granting and revoking privs are disabled.
Step 02) Show users and hosts
select concat(''',user,'''@''',host,'''') userhost,password from mysql.user;
Step 03) Check your password to make sure it works
select user,host from mysql.user where password=password('YourMySQLPassword');
If your password produces no output for this query, you have a bad password.
If your password produces output for this query, look at the users and hosts. If your host value is '%', your should be able to connect from anywhere. If your host is 'localhost', you should be able to connect locally.
Make user you have 'root'@'localhost' defined.
Once you have done what is needed, just restart mysql normally
service mysql restart
If you are able to connect successfully on the macbook, run this query:
SELECT USER(),CURRENT_USER();
USER() reports how you attempted to authenticate in MySQL
CURRENT_USER() reports how you were allowed to authenticate in MySQL
Let us know what happens !!!
UPDATE 2012-02-13 20:47 EDT
Login to the remote server and repeat Step 1-3
See if any user allows remote access (i.e, host in mysql.user is '%'). If you do not, then add 'user'@'%' to mysql.user.

UCanAccess is a pure Java JDBC driver that allows us to read from and write to Access databases without using ODBC. It uses two other packages, Jackcess and HSQLDB, to perform these tasks. The following is a brief overview of how to get it set up.
If your project uses Maven you can simply include UCanAccess via the following coordinates:
groupId: net.sf.ucanaccess
artifactId: ucanaccess
The following is an excerpt from pom.xml
, you may need to update the <version>
to get the most recent release:
<dependencies>
<dependency>
<groupId>net.sf.ucanaccess</groupId>
<artifactId>ucanaccess</artifactId>
<version>4.0.4</version>
</dependency>
</dependencies>
As mentioned above, UCanAccess requires Jackcess and HSQLDB. Jackcess in turn has its own dependencies. So to use UCanAccess you will need to include the following components:
UCanAccess (ucanaccess-x.x.x.jar)
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
Jackcess (jackcess-2.x.x.jar)
commons-lang (commons-lang-2.6.jar, or newer 2.x version)
commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)
Fortunately, UCanAccess includes all of the required JAR files in its distribution file. When you unzip it you will see something like
ucanaccess-4.0.1.jar
/lib/
commons-lang-2.6.jar
commons-logging-1.1.1.jar
hsqldb.jar
jackcess-2.1.6.jar
All you need to do is add all five (5) JARs to your project.
NOTE: Do not add
loader/ucanload.jar
to your build path if you are adding the other five (5) JAR files. TheUcanloadDriver
class is only used in special circumstances and requires a different setup. See the related answer here for details.
Eclipse: Right-click the project in Package Explorer and choose Build Path > Configure Build Path...
. Click the "Add External JARs..." button to add each of the five (5) JARs. When you are finished your Java Build Path should look something like this
NetBeans: Expand the tree view for your project, right-click the "Libraries" folder and choose "Add JAR/Folder...", then browse to the JAR file.
After adding all five (5) JAR files the "Libraries" folder should look something like this:
IntelliJ IDEA: Choose File > Project Structure...
from the main menu. In the "Libraries" pane click the "Add" (+
) button and add the five (5) JAR files. Once that is done the project should look something like this:
Now "U Can Access" data in .accdb and .mdb files using code like this
// assumes...
// import java.sql.*;
Connection conn=DriverManager.getConnection(
"jdbc:ucanaccess://C:/__tmp/test/zzz.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT [LastName] FROM [Clients]");
while (rs.next()) {
System.out.println(rs.getString(1));
}
At the time of writing this Q&A I had no involvement in or affiliation with the UCanAccess project; I just used it. I have since become a contributor to the project.
A friend function is not a member function, so the problem is that you declare operator<<
as a friend of A
:
friend ostream& operator<<(ostream&, A&);
then try to define it as a member function of the class logic
ostream& logic::operator<<(ostream& os, A& a)
^^^^^^^
Are you confused about whether logic
is a class or a namespace?
The error is because you've tried to define a member operator<<
taking two arguments, which means it takes three arguments including the implicit this
parameter. The operator can only take two arguments, so that when you write a << b
the two arguments are a
and b
.
You want to define ostream& operator<<(ostream&, const A&)
as a non-member function, definitely not as a member of logic
since it has nothing to do with that class!
std::ostream& operator<<(std::ostream& os, const A& a)
{
return os << a.number;
}
If you dont need a feedback about the requested data and also dont need any interactivity between the opener and the popup, you can post a hidden form into the popup:
Example:
<form method="post" target="popup" id="formID" style="display:none" action="https://example.com/barcode/generate" >
<input type="hidden" name="packing_slip" value="35592" />
<input type="hidden" name="reference" value="0018439" />
<input type="hidden" name="total_boxes" value="1" />
</form>
<script type="text/javascript">
window.open('about:blank','popup','width=300,height=200')
document.getElementById('formID').submit();
</script>
Otherwise you could use jsonp. But this works only, if you have access to the other Server, because you have to modify the response.
The solution to this problem is very simple...
If you don't have Ant build file then generate it. In Eclipse you can easily create a Ant file.
Refer to the link to create Ant build file [http://www.codejava.net/ides/eclipse/how-to-create-ant-build-file-for-existing-java-project-in-eclipse].
Now follow the given steps:
1) Add your Ant build file in Ant view that is in view window.
2) right click on your Ant build file and select Run As and the second option in that "Ant Build".
3) Now a dialog box will open with various options and tabs.
4) Select the JRE tab.
5) You will see three radio buttons and they will be having JRE or JDK selected as an option.
6) Look carefully if the radio button options are having JRE as selected then change it to JDK.
7) Click apply.
That's it...!!!
public function __construct() {
$parameters = func_get_args();
...
}
$o = new MyClass('One', 'Two', 3);
Now $paramters will be an array with the values 'One', 'Two', 3.
Edit,
I can add that
func_num_args()
will give you the number of parameters to the function.
In my case looking in the servers window only showed a tomcat server that I had never used for this project. My SpringBoot project used an embedded tomcat server and it did not stop when my application finished. This button which I indicate with a red arrow will stop the application and the Tomcat server so next time I run the application I will not get the error that an Instance of Tomcat is already running on port 8080.
actual error messages:
Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port.
Caused by: java.net.BindException: Address already in use Caused by: org.apache.catalina.LifecycleException: service.getName(): "Tomcat"; Protocol handler start failed
I will now be looking into a way to shut down all services on completion of my SpringBoot Consuming Rest application in this tutorial https://spring.io/guides/gs/consuming-rest/
An easier way to determine what dependencies a native DLL has is to use Dependency Walker - http://www.dependencywalker.com/
I analysed the native DLL and discovered that it depended on MSVCR120.DLL and MSVCP120.DLL, both of which were not installed on my staging server in the System32 directory. I installed the C++ runtime on my staging server and the issue was resolved.
I have been doing PHP for my project, and I can say that the following code works for me. You should try it.
echo '<input type = "text" value = '.$idtest.'>';
The comment by MK pointed me in the right direction.
In the case of Apache 2.4 and up, there are different defaults and a new directive.
I am running Apache 2.4.6, and I had to add the following directives to get it working:
SSLProxyEngine on
SSLProxyVerify none
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
SSLProxyCheckPeerExpire off
lambda
is an anonymous function, it is equivalent to:
def func(p):
return p.totalScore
Now max
becomes:
max(players, key=func)
But as def
statements are compound statements they can't be used where an expression is required, that's why sometimes lambda
's are used.
Note that lambda
is equivalent to what you'd put in a return statement of a def
. Thus, you can't use statements inside a lambda
, only expressions are allowed.
What does max
do?
max(a, b, c, ...[, key=func]) -> value
With a single iterable argument, return its largest item. With two or more arguments, return the largest argument.
So, it simply returns the object that is the largest.
How does key
work?
By default in Python 2 key
compares items based on a set of rules based on the type of the objects (for example a string is always greater than an integer).
To modify the object before comparison, or to compare based on a particular attribute/index, you've to use the key
argument.
Example 1:
A simple example, suppose you have a list of numbers in string form, but you want to compare those items by their integer value.
>>> lis = ['1', '100', '111', '2']
Here max
compares the items using their original values (strings are compared lexicographically so you'd get '2'
as output) :
>>> max(lis)
'2'
To compare the items by their integer value use key
with a simple lambda
:
>>> max(lis, key=lambda x:int(x)) # compare `int` version of each item
'111'
Example 2: Applying max
to a list of tuples.
>>> lis = [(1,'a'), (3,'c'), (4,'e'), (-1,'z')]
By default max
will compare the items by the first index. If the first index is the same then it'll compare the second index. As in my example, all items have a unique first index, so you'd get this as the answer:
>>> max(lis)
(4, 'e')
But, what if you wanted to compare each item by the value at index 1? Simple: use lambda
:
>>> max(lis, key = lambda x: x[1])
(-1, 'z')
Comparing items in an iterable that contains objects of different type:
List with mixed items:
lis = ['1','100','111','2', 2, 2.57]
In Python 2 it is possible to compare items of two different types:
>>> max(lis) # works in Python 2
'2'
>>> max(lis, key=lambda x: int(x)) # compare integer version of each item
'111'
But in Python 3 you can't do that any more:
>>> lis = ['1', '100', '111', '2', 2, 2.57]
>>> max(lis)
Traceback (most recent call last):
File "<ipython-input-2-0ce0a02693e4>", line 1, in <module>
max(lis)
TypeError: unorderable types: int() > str()
But this works, as we are comparing integer version of each object:
>>> max(lis, key=lambda x: int(x)) # or simply `max(lis, key=int)`
'111'
You might want to put the absolutely aligned div in a relatively aligned container - this way it will still be contained into the container rather than the browser window.
<div style="position: relative;background-color: blue; width: 600px; height: 800px;">
<div style="position: absolute; bottom: 5px; background-color: green">
TEST (C) 2010
</div>
</div>
Stub is a function definition that has correct function name, the correct number of parameters and produces dummy result of the correct type.
It helps to write the test and serves as a kind of scaffolding to make it possible to run the examples even before the function design is complete
You can use lock variables "a" and "b" and synchronize them for locking the "critical section" in reverse order. Eg. Notify "a" then Lock "b" ,"PRINT", Notify "b" then Lock "a".
Please refer the below the code :
public class EvenOdd {
static int a = 0;
public static void main(String[] args) {
EvenOdd eo = new EvenOdd();
A aobj = eo.new A();
B bobj = eo.new B();
aobj.a = Lock.lock1;
aobj.b = Lock.lock2;
bobj.a = Lock.lock2;
bobj.b = Lock.lock1;
Thread t1 = new Thread(aobj);
Thread t2 = new Thread(bobj);
t1.start();
t2.start();
}
static class Lock {
final static Object lock1 = new Object();
final static Object lock2 = new Object();
}
class A implements Runnable {
Object a;
Object b;
public void run() {
while (EvenOdd.a < 10) {
try {
System.out.println(++EvenOdd.a + " A ");
synchronized (a) {
a.notify();
}
synchronized (b) {
b.wait();
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
class B implements Runnable {
Object a;
Object b;
public void run() {
while (EvenOdd.a < 10) {
try {
synchronized (b) {
b.wait();
System.out.println(++EvenOdd.a + " B ");
}
synchronized (a) {
a.notify();
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
}
OUTPUT :
1 A
2 B
3 A
4 B
5 A
6 B
7 A
8 B
9 A
10 B

This will trim off any combination of carriage returns and newlines from the end of s
:
s = s.TrimEnd(new char[] { '\r', '\n' });
Edit: Or as JP kindly points out, you can spell that more succinctly as:
s = s.TrimEnd('\r', '\n');
So I had the same issue, but it was because I was saving the access token but not using it. It could be because I'm super sleepy because of due dates, or maybe I just didn't think about it! But in case anyone else is in the same situation:
When I log in the user I save the access token:
$facebook = new Facebook(array(
'appId' => <insert the app id you get from facebook here>,
'secret' => <insert the app secret you get from facebook here>
));
$accessToken = $facebook->getAccessToken();
//save the access token for later
Now when I make requests to facebook I just do something like this:
$facebook = new Facebook(array(
'appId' => <insert the app id you get from facebook here>,
'secret' => <insert the app secret you get from facebook here>
));
$facebook->setAccessToken($accessToken);
$facebook->api(... insert own code here ...)
As @samwize pointed out, the way of paginating is by using
setViewControllers:array
Here's the way I did it: I have my datasource and the delegate separate. You can call this method and only change the "next" view. Previously you have to apply the paging rules. That is, you have to check direction and the next controller. If you use that method with your custom datasource the array of controllers that you're displaying won't change (since you'll use a custom array on a NSObject subclass).
Using your own datasource the method just sets a new view (with specific direction). Since you will still controll the pages that will display when normally swiping.
STR_TO_DATE allows you to do this, and it has a format argument.
It worked for me, but only with https link in repository setting (Repository => Repository Settings). You need to change setting to:
URL / path: https://**********.com/username/project.git Host Type - Stash Host Root URL - your root URL to GitLab (example:https://**********.com/) Username - leave blank
or in some cases if you have ssh url like:
[email protected]:USER/REPOSITORY.git
and your email like:
[email protected]
then this settings should be work:
URL / path: https://test%[email protected]:USER/REPOSITORY.git
import re
re.sub('<.*?>', '', string)
"i think mabe 124 + but I don't have a big experience it just how I see it in my eyes fun stuff"
The re.sub
function takes a regular expresion and replace all the matches in the string with the second parameter. In this case, we are searching for all tags ('<.*?>'
) and replacing them with nothing (''
).
The ?
is used in re
for non-greedy searches.

delete from yourTable
where Id not in (
select min(id)
from yourTable
group by <Unique Columns>
)
where id is whatever is your unique id in the table. (Could be customerNumber or whatever)
If you don't have a Unique Id, you can add one (every SQL table should already have Id as first column, but
ALTER TABLE yourTable
ADD Id int identity(1,1)
Do your delete (above) and then drop the column.
Better than creating a whole new table, or any of the other cryptic stuff I've seen. Note, pretty much the same as in a comment here, but this is what I've done for years.
I am surprised that the connection string works for you, because it is missing a semi-colon. Set is only used with objects, so you would not say Set strNaam.
Set cn = CreateObject("ADODB.Connection")
With cn
.Provider = "Microsoft.Jet.OLEDB.4.0"
.ConnectionString = "Data Source=D:\test.xls " & _
";Extended Properties=""Excel 8.0;HDR=Yes;"""
.Open
End With
strQuery = "SELECT * FROM [Sheet1$E36:E38]"
Set rs = cn.Execute(strQuery)
Do While Not rs.EOF
For i = 0 To rs.Fields.Count - 1
Debug.Print rs.Fields(i).Name, rs.Fields(i).Value
strNaam = rs.Fields(0).Value
Next
rs.MoveNext
Loop
rs.Close
There are other ways, depending on what you want to do, such as GetString (GetString Method Description).
The closest equivalent are the Windows Scheduled Tasks (Control Panel -> Scheduled Tasks), though they are a far, far cry from cron.
The biggest difference (to me) is that they require a user to be logged into the Windows box, and a user account (with password and all), which makes things a nightmare if your local security policy requires password changes periodically. I also think it is less flexible than cron as far as setting intervals for items to run.
You was near:
this["instance_" + a] = function () {...};
_x000D_
{...};
I had this problem. Just run SQL Server as administrator
You are missing a space between Basic
and the encoded username and password.
headers.set('Authorization', 'Basic ' + base64.encode(username + ":" + password));
I was able to achieve this by using set -x
in the main script (which makes the script print out every command that is executed) and writing a wrapper script which just shows the last line of output generated by set -x
.
This is the main script:
#!/bin/bash
set -x
echo some command here
echo last command
And this is the wrapper script:
#!/bin/sh
./test.sh 2>&1 | grep '^\+' | tail -n 1 | sed -e 's/^\+ //'
Running the wrapper script produces this as output:
echo last command
as your service is already setup, simply add a broadcast receiver in your service:
private final BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if(action.equals("android.provider.Telephony.SMS_RECEIVED")){
//action for sms received
}
else if(action.equals(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED)){
//action for phone state changed
}
}
};
in your service's onCreate
do this:
IntentFilter filter = new IntentFilter();
filter.addAction("android.provider.Telephony.SMS_RECEIVED");
filter.addAction(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED);
filter.addAction("your_action_strings"); //further more
filter.addAction("your_action_strings"); //further more
registerReceiver(receiver, filter);
and in your service's onDestroy
:
unregisterReceiver(receiver);
and you are good to go to receive broadcast for what ever filters you mention in onCreate
. Make sure to add any permission if required. for e.g.
<uses-permission android:name="android.permission.RECEIVE_SMS" />
Just change the DropDownStyle
to DropDownList
. Or if you want it completely read only you can set Enabled = false
, or if you don't like the look of that I sometimes have two controls, one readonly textbox and one combobox and then hide the combo and show the textbox if it should be completely readonly and vice versa.
Javascript has no actual classes rather it uses a system of prototypal inheritance in which objects 'inherit' from other objects via their prototype chain. This is best explained via code itself:
function Foo() {};_x000D_
// creates a new function object_x000D_
_x000D_
Foo.prototype.talk = function () {_x000D_
console.log('hello~\n');_x000D_
};_x000D_
// put a new function (object) on the prototype (object) of the Foo function object_x000D_
_x000D_
var a = new Foo;_x000D_
// When foo is created using the new keyword it automatically has a reference _x000D_
// to the prototype property of the Foo function_x000D_
_x000D_
// We can show this with the following code_x000D_
console.log(Object.getPrototypeOf(a) === Foo.prototype); _x000D_
_x000D_
a.talk(); // 'hello~\n'_x000D_
// When the talk method is invoked it will first look on the object a for the talk method,_x000D_
// when this is not present it will look on the prototype of a (i.e. Foo.prototype)_x000D_
_x000D_
// When you want to call_x000D_
// Foo.talk();_x000D_
// this will not work because you haven't put the talk() property on the Foo_x000D_
// function object. Rather it is located on the prototype property of Foo._x000D_
_x000D_
// We could make it work like this:_x000D_
Foo.sayhi = function () {_x000D_
console.log('hello there');_x000D_
};_x000D_
_x000D_
Foo.sayhi();_x000D_
// This works now. However it will not be present on the prototype chain _x000D_
// of objects we create out of Foo
_x000D_
This is what worked from me using an array as input. First uncheck all options, then click on the chosen options using jquery
var dimensions = ["Dates","Campaigns","Placements"];
$(".input-dimensions").multiselect("uncheckAll");
for( var dim in dimensions) {
$(".input-dimensions").multiselect("widget")
.find(":checkbox[value='" + dimensions[dim] + "']").click();
}
There's already a question about this, you could perhaps read it
There's no Clone() method as it exists in Java for example, but you could include a copy constructor in your clases, that's another good approach.
class A
{
private int attr
public int Attr
{
get { return attr; }
set { attr = value }
}
public A()
{
}
public A(A p)
{
this.attr = p.Attr;
}
}
This would be an example, copying the member 'Attr' when building the new object.
For Intellij IDEA Community 2019.1 you will need to follow these steps :
File -> New -> Edit File Templates.. -> Class -> /* Created by ${USER} on ${DATE} */
When debugging optimized programs (which may be necessary if the bug doesn't show up in debug builds), you often have to understand assembly compiler generated.
In your particular case, return value of cpnd_find_exact_ckptinfo
will be stored in the register which is used on your platform for return values. On ix86
, that would be %eax
. On x86_64
: %rax
, etc. You may need to google for '[your processor] procedure calling convention' if it's none of the above.
You can examine that register in GDB
and you can set it. E.g. on ix86
:
(gdb) p $eax
(gdb) set $eax = 0
The basic idea of Servlet container is using Java to dynamically generate the web page on the server side using Servlets and JSP. So servlet container is essentially a part of a web server that interacts with the servlets.
There is no reason not to use C <stdio.h>
in C++, and in fact it is often the optimal choice.
#include <stdio.h>
int
main() // (void) not necessary in C++
{
int c;
while ((c = getchar()) != EOF) {
// do something with 'c' here
}
return 0; // technically not necessary in C++ but still good style
}
Socket.IO allows you to “namespace” your sockets, which essentially means assigning different endpoints or paths.
This might help: http://socket.io/docs/rooms-and-namespaces/

A former project of mine was going to use freely downloadable data from EODData.
select substring(your_field, CHARINDEX(';',your_field)+1 ,CHARINDEX('[',your_field)-CHARINDEX(';',your_field)-1) from your_table
Can't get the others to work. I believe you just want what is in between ';' and '[' in all cases regardless of how long the string in between is. After specifying the field in the substring function, the second argument is the starting location of what you will extract. That is, where the ';' is + 1 (fourth position - the c), because you don't want to include ';'. The next argument takes the location of the '[' (position 14) and subtracts the location of the spot after the ';' (fourth position - this is why I now subtract 1 in the query). This basically says substring(field,location I want substring to begin, how long I want substring to be). I've used this same function in other cases. If some of the fields don't have ';' and '[', you'll want to filter those out in the "where" clause, but that's a little different than the question. If your ';' was say... ';;;', you would use 3 instead of 1 in the example. Hope this helps!
You need to make your datetime objects timezone aware. from the datetime docs:
There are two kinds of date and time objects: “naive” and “aware”. This distinction refers to whether the object has any notion of time zone, daylight saving time, or other kind of algorithmic or political time adjustment. Whether a naive datetime object represents Coordinated Universal Time (UTC), local time, or time in some other timezone is purely up to the program, just like it’s up to the program whether a particular number represents metres, miles, or mass. Naive datetime objects are easy to understand and to work with, at the cost of ignoring some aspects of reality.
When you have an aware datetime object, you can use isoformat() and get the output you need.
To make your datetime objects aware, you'll need to subclass tzinfo, like the second example in here, or simpler - use a package that does it for you, like pytz or python-dateutil
Using pytz, this would look like:
import datetime, pytz
datetime.datetime.now(pytz.timezone('US/Central')).isoformat()
You can also control the output format, if you use strftime with the '%z' format directive like
datetime.datetime.now(pytz.timezone('US/Central')).strftime('%Y-%m-%dT%H:%M:%S.%f%z')
In order to pass the parameters you create new intent and put a parameter map:
Intent myIntent = new Intent(this, NewActivityClassName.class);
myIntent.putExtra("firstKeyName","FirstKeyValue");
myIntent.putExtra("secondKeyName","SecondKeyValue");
startActivity(myIntent);
In order to get the parameters values inside the started activity, you must call the get[type]Extra()
on the same intent:
// getIntent() is a method from the started activity
Intent myIntent = getIntent(); // gets the previously created intent
String firstKeyName = myIntent.getStringExtra("firstKeyName"); // will return "FirstKeyValue"
String secondKeyName= myIntent.getStringExtra("secondKeyName"); // will return "SecondKeyValue"
If your parameters are ints you would use getIntExtra()
instead etc.
Now you can use your parameters like you normally would.
You don't need to pass this
, there already is the event
object passed by default automatically, which contains event.target
which has the object it's coming from. You can lighten your syntax:
This:
<p onclick="doSomething()">
Will work with this:
function doSomething(){
console.log(event);
console.log(event.target);
}
You don't need to instantiate the event
object, it's already there. Try it out. And event.target
will contain the entire object calling it, which you were referencing as "this" before.
Now if you dynamically trigger doSomething() from somewhere in your code, you will notice that event
is undefined. This is because it wasn't triggered from an event of clicking. So if you still want to artificially trigger the event, simply use dispatchEvent
:

No need to pass this
everywhere, and you can keep your function signatures free from wiring information and simplify things.
Odds are good you did the right stuff on the back end in getting the date, but there's nothing to indicate that you didn't take that GMT time and format it according to your machine's current locale.
final Date currentTime = new Date();
final SimpleDateFormat sdf =
new SimpleDateFormat("EEE, MMM d, yyyy hh:mm:ss a z");
// Give it to me in GMT time.
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
System.out.println("GMT time: " + sdf.format(currentTime));
The key is to use your own DateFormat, not the system provided one. That way you can set the DateFormat's timezone to what you wish, instead of it being set to the Locale's timezone.
I know I am late to the party, but how about this?
const char* dayNames[] = { [Sunday] = "Sunday", [Monday] = "Monday", /*and so on*/ };
printf("%s", dayNames[Sunday]); // prints "Sunday"
This way, you do not have to manually keep the enum
and the char*
array in sync. If you are like me, chances are that you will later change the enum
, and the char*
array will print invalid strings.
This may not be a feature universally supported. But afaik, most of the mordern day C compilers support this designated initialier style.

Support for TLS 1.0 and 1.1 was dropped for PyPI. If your system does not use a more recent version, it could explain your error.
Could you try reinstalling pip system-wide, to update your system dependencies to a newer version of TLS?
This seems to be related to Unable to install Python libraries
See Dominique Barton's answer:
Apparently pip is trying to access PyPI via HTTPS (which is encrypted and fine), but with an old (insecure) SSL version. Your system seems to be out of date. It might help if you update your packages.
On Debian-based systems I'd try:
apt-get update && apt-get upgrade python-pip
On Red Hat Linux-based systems:
yum update python-pip # (or python2-pip, at least on Red Hat Linux 7)
On Mac:
sudo easy_install -U pip
You can also try to update
openssl
separately.
TagLib Sharp has support for reading ID3 tags.

Very likely your filesystem is out of sync with your Eclipse... Resource is out of sync with the file system. Using SVN? If you "Refresh" all of your projects in explorer, speed returns to normal.
After iOS 7, this process has been simplified down to (swift 3.0):
// For registering nib files
tableView.register(UINib(nibName: "MyCell", bundle: Bundle.main), forCellReuseIdentifier: "cell")
// For registering classes
tableView.register(MyCellClass.self, forCellReuseIdentifier: "cell")
(Note) This is also achievable by creating the cells in the
.xib
or.stroyboard
files, as prototype cells. If you need to attach a class to them, you can select the cell prototype and add the corresponding class (must be a descendant ofUITableViewCell
, of course).
And later on, dequeued using (swift 3.0):
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
let cell : UITableViewCell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
cell.textLabel?.text = "Hello"
return cell
}
The difference being that this new method not only dequeues the cell, it also creates if non-existant (that means that you don't have to do if (cell == nil)
shenanigans), and the cell is ready to use just as in the example above.
(Warning)
tableView.dequeueReusableCell(withIdentifier:for:)
has the new behavior, if you call the other one (withoutindexPath:
) you get the old behavior, in which you need to check fornil
and instance it yourself, notice theUITableViewCell?
return value.
if let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as? MyCellClass
{
// Cell be casted properly
cell.myCustomProperty = true
}
else
{
// Wrong type? Wrong identifier?
}
And of course, the type of the associated class of the cell is the one you defined in the .xib file for the UITableViewCell
subclass, or alternatively, using the other register method.
Ideally, your cells have been already configured in terms of appearance and content positioning (like labels and image views) by the time you registered them, and on the cellForRowAtIndexPath
method you simply fill them in.
class MyCell : UITableViewCell
{
// Can be either created manually, or loaded from a nib with prototypes
@IBOutlet weak var labelSomething : UILabel? = nil
}
class MasterViewController: UITableViewController
{
var data = ["Hello", "World", "Kinda", "Cliche", "Though"]
// Register
override func viewDidLoad()
{
super.viewDidLoad()
tableView.register(MyCell.self, forCellReuseIdentifier: "mycell")
// or the nib alternative
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return data.count
}
// Dequeue
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: "mycell", for: indexPath) as! MyCell
cell.labelSomething?.text = data[indexPath.row]
return cell
}
}
And of course, this is all available in ObjC with the same names.
On Windows maybe the play "run 9001" will not work. You have to change the play.bat file. See Ticket
I had the same problem and what ended up being the issue was the RAM size: apparently 1024 (or whatever size) is different from 1024MB. Make sure you specify the units and it should work for you.
Have you checked in console if data from form is properly serialized? Is ajax request successful? Also you didn't close placeholder quote in, which can cause some problems:
<textarea name="comentarii" cols="36" rows="5" placeholder="Message>
Dictionary<string, Type> typeCache;
...
public static bool TryFindType(string typeName, out Type t) {
lock (typeCache) {
if (!typeCache.TryGetValue(typeName, out t)) {
foreach (Assembly a in AppDomain.CurrentDomain.GetAssemblies()) {
t = a.GetType(typeName);
if (t != null)
break;
}
typeCache[typeName] = t; // perhaps null
}
}
return t != null;
}
You must have used the object, released it ("disconnect"), and used it again. Release object only after you're finished with it, or when calling Form_Closing
.
Use cURL
,
Check if you have it via phpinfo();
And for the code:
function getHtml($url, $post = null) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
if(!empty($post)) {
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
}
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
You could avoid memory allocation. There are many variants, all having problems in case of multithreading environment.
I prefer this kind of implementation (actually, it is not correctly said I prefer, because I avoid singletons as much as possible):
class Singleton
{
private:
Singleton();
public:
static Singleton& instance()
{
static Singleton INSTANCE;
return INSTANCE;
}
};
It has no dynamic memory allocation.
Also, especially if you are a developer, make sure that you are in fact connecting to the IIS server and not to the IIS Express that comes with Visual Studio. If you are debugging a project, it's just as easy if not easier sometimes to think you are connected to IIS when you in fact aren't.
Even if you've enabled Windows Authentication and disabled Anonymous Authentication on IIS, this won't make any difference to your Visual Studio simulation.
I get the same error in WP when I use php ver 7.1.6 - just take your php version back to 7.0.20 and the error will disappear.
I found out that single quote > double quote > wrapped in ampersands did work. So, for me it looks like this:

Use cbind
e.g.
df <- data.frame(b = runif(6), c = rnorm(6))
cbind(a = 0, df)
giving:

a b c
1 0 0.5437436 -0.1374967
2 0 0.5634469 -1.0777253

It can be done through "Import/Export Data..." in SQL Server Management Studio
Don't forget "compare with clipboard".
Something that I use all the time in IntelliJ and which has no equivalent in Eclipse.
Found how.
First, configure the text of titleLabel
(because of styles, i.e, bold, italic, etc). Then, use setTitleEdgeInsets
considering the width of your image:
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button setTitle:title forState:UIControlStateNormal];
[button.titleLabel setFont:[UIFont boldSystemFontOfSize:10.0]];
// Left inset is the negative of image width.
[button setTitleEdgeInsets:UIEdgeInsetsMake(0.0, -image.size.width, -25.0, 0.0)];
After that, use setTitleEdgeInsets
considering the width of text bounds:
[button setImage:image forState:UIControlStateNormal];
// Right inset is the negative of text bounds width.
[button setImageEdgeInsets:UIEdgeInsetsMake(-15.0, 0.0, 0.0, -button.titleLabel.bounds.size.width)];
Now the image and the text will be centered (in this example, the image appears above the text).
Cheers.

Have your Activity
implement OnFocusChangeListener()
if you want a factorized use of this interface,
example:
public class Shops extends AppCompatActivity implements View.OnFocusChangeListener{
In your OnCreate
you can add a listener for example:
editTextResearch.setOnFocusChangeListener(this);
editTextMyWords.setOnFocusChangeListener(this);
editTextPhone.setOnFocusChangeListener(this);
then android studio will prompt you to add the method from the interface, accept it... it will be like:
@Override
public void onFocusChange(View v, boolean hasFocus) {
// todo your code here...
}
and as you've got a factorized code, you'll just have to do that:
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
editTextResearch.setText("");
editTextMyWords.setText("");
editTextPhone.setText("");
}
if (!hasFocus){
editTextResearch.setText("BlaBlaBla");
editTextMyWords.setText(" One Two Tree!");
editTextPhone.setText("\"your phone here:\"");
}
}
anything you code in the !hasFocus
is for the behavior of the item that loses focus, that should do the trick! But beware that in such state, the change of focus might overwrite the user's entries!
You can use Detach/Attach Option in SQL Server Management Studio.
Check this: Move a Database Using Detach and Attach
Because Option 2 creates a new List
reference, and then creates an n
element array from the List
(option 1 perfectly sizes the output array). However, first you need to fix the off by one bug. Use <
(not <=
). Like,
String[] out = new String[n];
for(int i = 0; i < n; i++) {
out[i] = in.get(i);
}
Here is a method using a lookup table of thresholds and associated colours to map the colours to the variable of interest.
# make a grid 'Grd' of points and number points for side of square 'GrdD'

GrdD <- length(unique(Grd$Var1))
# Add z-values to the grid points
Grd$z <- rnorm(length(Grd$Var1), mean = 10, sd =2)
# Make a vector of thresholds 'Brks' to colour code z
Brks <- c(seq(0,18,3),Inf)
# Make a vector of labels 'Lbls' for the colour threhsolds
Lbls <- Lbls <- c('0-3','3-6','6-9','9-12','12-15','15-18','>18')
# Make a vector of colours 'Clrs' for to match each range
Clrs <- c("grey50","dodgerblue","forestgreen","orange","red","purple","magenta")
# Make up lookup dataframe 'LkUp' of the lables and colours
LkUp <- data.frame(cbind(Lbls,Clrs),stringsAsFactors = FALSE)
# Add a new variable 'Lbls' the grid dataframe mapping the labels based on z-value
Grd$Lbls <- as.character(cut(Grd$z, breaks = Brks, labels = Lbls))
# Add a new variable 'Clrs' to the grid dataframe based on the Lbls field in the grid and lookup table
Grd <- merge(Grd,LkUp, by.x = 'Lbls')
# Plot the grid using the 'Clrs' field for the colour of each point

Android handles transparency across views and drawables (including PNG images) natively, so the scenario you describe (a partially transparent ImageView
in front of a Gallery
) is certainly possible.
If you're having problems it may be related to either the layout or your image. I've replicated the layout you describe and successfully achieved the effect you're after. Here's the exact layout I used.
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/gallerylayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Gallery
android:id="@+id/overview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<ImageView
android:id="@+id/navigmaske"
android:background="#0000"
android:src="@drawable/navigmask"
android:scaleType="fitXY"
android:layout_alignTop="@id/overview"
android:layout_alignBottom="@id/overview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</RelativeLayout>
Note that I've changed the parent RelativeLayout
to a height and width of fill_parent
as is generally what you want for a main Activity. Then I've aligned the top and bottom of the ImageView
to the top and bottom of the Gallery
to ensure it's centered in front of it.
I've also explicitly set the background of the ImageView
to be transparent.
As for the image drawable itself, if you put the PNG file somewhere for me to look at I can use it in my project and see if it's responsible.
Because you allow for
all fields minus those within "b".
when submitting "a", the following would work, using regular web-forms without fancy JavaScript tricks:
Step 1. Put each form on its own web page.
Step 2. Insert an iframe wherever you want this sub-form to appear.
Step 3. Profit.
I tried to use a code-playground website to show a demo, but many of them prohibit embedding their websites in iframes, even within their own domain.
I have created my own git alias to do exactly this. I'm calling it git freebase
! It will take your existing messy, unrebasable feature branch and recreate it so that it becomes a new branch with the same name with its commits squashed into one commit and rebased onto the branch you specify (master by default). At the very end, it will allow you to use whatever commit message you like for your newly "freebased" branch.
Install it by placing the following alias in your .gitconfig:
[alias]
freebase = "!f() { \
TOPIC="$(git branch | grep '\\*' | cut -d ' ' -f2)"; \
NEWBASE="${1:-master}"; \
PREVSHA1="$(git rev-parse HEAD)"; \
echo "Freebaseing $TOPIC onto $NEWBASE, previous sha1 was $PREVSHA1"; \
echo "---"; \
git reset --hard "$NEWBASE"; \
git merge --squash "$PREVSHA1"; \
git commit; \
}; f"
Use it from your feature branch by running:
git freebase <new-base>
I've only tested this a few times, so read it first and make sure you want to run it. As a little safety measure it does print the starting sha1 so you should be able to restore your old branch if anything goes wrong.
I'll be maintaining it in my dotfiles repo on github: https://github.com/stevecrozz/dotfiles/blob/master/.gitconfig

An optional parameter is just tagged with an attribute. This attribute tells the compiler to insert the default value for that parameter at the call-site.
The call obj2.TestMethod();
is replaced by obj2.TestMethod(false);
when the C# code gets compiled to IL, and not at JIT-time.
So in a way it's always the caller providing the default value with optional parameters. This also has consequences on binary versioning: If you change the default value but don't recompile the calling code it will continue to use the old default value.
On the other hand, this disconnect means you can't always use the concrete class and the interface interchangeably.
You already can't do that if the interface method was implemented explicitly.
You would think that simply authenticating a user in Active Directory would be a pretty simple process using LDAP in PHP without the need for a library. But there are a lot of things that can complicate it pretty fast:
It's actually easier in most cases to use a LDAP library supporting the above. I ultimately ended up rolling my own library which handles all the above points: LdapTools (Well, not just for authentication, it can do much more). It can be used like the following:
use LdapTools\Configuration;
use LdapTools\DomainConfiguration;
use LdapTools\LdapManager;
$domain = (new DomainConfiguration('example.com'))
->setUsername('username') # A separate AD service account used by your app
->setPassword('password')
->setServers(['dc1', 'dc2', 'dc3'])
->setUseTls(true);
$config = new Configuration($domain);
$ldap = new LdapManager($config);
if (!$ldap->authenticate($username, $password, $message)) {
echo "Error: $message";
} else {
// Do something...
}
The authenticate call above will:
There are other libraries to do this too (Such as Adldap2). However, I felt compelled enough to provide some additional information as the most up-voted answer is actually a security risk to rely on with no input validation done and not using TLS.
I think you need to use for example:
aws ecs list-container-instances --cluster default --region us-east-1
This depends of your region of course.
Use the collapse
argument to paste
:

The detach/copy/attach method will take down the database. That's not something you'd want in production.
The backup/restore will only work if you have write permissions to the production server. I work with Amazon RDS and I don't.
The import/export method doesn't really work because of foreign keys - unless you do tables one by one in the order they reference one another. You can do an import/export to a new database. That will copy all the tables and data, but not the foreign keys.
This sounds like a common operation one needs to do with database. Why isn't SQL Server handling this properly? Every time I had to do this it was frustrating.
That being said, the only painless solution I've encountered was Sql Azure Migration Tool which is maintained by the community. It works with SQL Server too.
public class InitHelloWorld implements BeanPostProcessor {
public Object postProcessBeforeInitialization(Object bean,
String beanName) throws BeansException {
System.out.println("BeforeInitialization : " + beanName);
return bean; // you can return any other object as well

public Object postProcessAfterInitialization(Object bean,
String beanName) throws BeansException {
System.out.println("AfterInitialization : " + beanName);
return bean; // you can return any other object as well

Pretty simple solution may be Console 2, redefine keys and you go.
I do not think that you can do this easily. you should consider this answer here:
How can I display a pdf document into a Webview?
basically you'll be able to see a pdf if it is hosted online via google documents, but not if you have it in your device (you'll need a standalone reader for that)
You should quote your array keys:
$department = mysql_real_escape_string($_POST['department']);
$name = mysql_real_escape_string($_POST['name']);
$email = mysql_real_escape_string($_POST['email']);
$message = mysql_real_escape_string($_POST['message']);
As is, it was looking for constants called department
, name
, email
, message
, etc. When it doesn't find such a constant, PHP (bizarrely) interprets it as a string ('department', etc). Obviously, this can easily break if you do defined such a constant later (though it's bad style to have lower-case constants).
Note: This answer predates the Unicode requirement; see the comments.
Just cast it:
CString s;
const TCHAR* x = (LPCTSTR) s;
It works because CString has a cast operator to do exactly this.
Using TCHAR makes your code Unicode-independent; if you're not concerned about Unicode you can simply use char
instead of TCHAR
.
The approved solution doesn't work in my case, so my solution is the following one:
''' The column name in the example case is "Unnamed: 7"
but it works with any other name ("Unnamed: 0" for example). '''
df.rename({"Unnamed: 7":"a"}, axis="columns", inplace=True)
# Then, drop the column as usual.
df.drop(["a"], axis=1, inplace=True)
Hope it helps others.

import csv
mycsv = csv.reader(open(myfilepath))
for row in mycsv:
text = row[1]
Following the comments to the SO question here, a best, more robust code would be:
import csv
with open(myfilepath, 'rb') as f:
mycsv = csv.reader(f)
for row in mycsv:
text = row[1]
............
Update: If what the OP actually wants is the last string in the last row of the csv file, there are several aproaches that not necesarily needs csv. For example,
fulltxt = open(mifilepath, 'rb').read()
laststring = fulltxt.split(',')[-1]
This is not good for very big files because you load the complete text in memory but could be ok for small files. Note that laststring
could include a newline character so strip it before use.
And finally if what the OP wants is the second string in line n (for n=2):
Update 2: This is now the same code than the one in the answer from J.F.Sebastian. (The credit is for him):
import csv
line_number = 2
with open(myfilepath, 'rb') as f:
mycsv = csv.reader(f)
mycsv = list(mycsv)
text = mycsv[line_number][1]
............
This error comes when you append this line os.path.join(os.path.dirname(__file__))
in python interactive shell.
Python Shell
doesn't detect current file path in __file__
and it's related to your filepath
in which you added this line
So you should write this line os.path.join(os.path.dirname(__file__))
in file.py
. and then run python file.py
, It works because it takes your filepath.
Try using float: left
(or right
) instead of display: inline
. Inline display replaces list-item display, which is what adds the bullet points.
You have quite a lot of options:
mysql -h hostname -u user database < path/to/test.sql
Close, but not the same. They're getting the same element, but the jQuery version is wrapped in a jQuery object.
The equivalent would be this
var contents = $('#contents').get(0);
or this
var contents = $('#contents')[0];
These will pull the element out of the jQuery object.
I've been trying to deploy a simple Angular 7 application, to an Azure Web App. Everything worked fine, until the point where you refreshed the page. Doing so, was presenting me with an 500 error - moved content. I've read both on the Angular docs and in around a good few forums, that I need to add a web.config file to my deployed solution and make sure the rewrite rule fallback to the index.html file. After hours of frustration and trial and error tests, I've found the error was quite simple: adding a tag around my file markup.
[Edit: The question originally asked how to get the mantissa and exponent.]
Where n is the number to get the real mantissa/exponent:
exponent = int(log(n))
mantissa = n / 10^exponent
Or, to get the answer you were looking for:
exponent = int(n)
mantissa = n - exponent
These are not Java exactly but should be easy to convert.

None of the other solution worked for me.
Even if I don't think its the best practice, I Had to add it into the code like this
configuration.addAnnotatedClass(com.myOrg.entities.Person.class);
here
public static SessionFactory getSessionFactory() {
Configuration configuration = new Configuration().configure();
configuration.addAnnotatedClass(com.myOrg.entities.Person.class);
StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder()
.applySettings(configuration.getProperties());
SessionFactory sessionFactory = configuration.buildSessionFactory(builder.build());
return sessionFactory;
}
This solution is similar to walid2mi (thank you for inspiration), but allows the standard console input by the Read-Host cmdlet.

When Python parses a function, it notes when a variable assignment is made. When there is an assignment, it assumes by default that that variable is a local variable. To declare that the assignment refers to a global variable, you must use the global
declaration.
When you access a variable in a function, its value is looked up using the LEGB scoping rules.
So, the first example
x = 1
def inc():
x += 5
inc()
produces an UnboundLocalError
because Python determined x
inside inc
to be a local variable,
while accessing x
works in your second example
def inc():
print x
because here, in accordance with the LEGB rule, Python looks for x
in the local scope, does not find it, then looks for it in the extended scope, still does not find it, and finally looks for it in the global scope successfully.
You can use list methods, remove and add
list.add(lowestIndex, element);
list.remove(highestIndex, element);
Try this, just an example:
u.UserTypeOptions = new SelectList(new[]
{
new { ID="1", Name="name1" },
new { ID="2", Name="name2" },
new { ID="3", Name="name3" },
}, "ID", "Name", 1);
Or
u.UserTypeOptions = new SelectList(new List<SelectListItem>
{
new SelectListItem { Selected = true, Text = string.Empty, Value = "-1"},
new SelectListItem { Selected = false, Text = "Homeowner", Value = "2"},
new SelectListItem { Selected = false, Text = "Contractor", Value = "3"},
},"Value","Text");
8388608 bytes is 8M, the default limit in PHP. Update your post_max_size
in php.ini to a larger value.
upload_max_filesize
sets the max file size that a user can upload while
post_max_size
sets the maximum amount of data that can be sent via a POST in a form.
So you can set upload_max_filesize
to 1 meg, which will mean that the biggest single file a user can upload is 1 megabyte, but they could upload 5 of them at once if the post_max_size
was set to 5.
java.exe
is the console app while javaw.exe
is windows app (console-less). You can't have Console
with javaw.exe
.

If no errors, you should be able to see the service reference in the object browser and all related methods.
Python is not Java, nor C/C++ -- you need to stop thinking that way to really utilize the power of Python.
Python does not have pass-by-value, nor pass-by-reference, but instead uses pass-by-name (or pass-by-object) -- in other words, nearly everything is bound to a name that you can then use (the two obvious exceptions being tuple- and list-indexing).
When you do spam = "green"
, you have bound the name spam
to the string object "green"
; if you then do eggs = spam
you have not copied anything, you have not made reference pointers; you have simply bound another name, eggs
, to the same object ("green"
in this case). If you then bind spam
to something else (spam = 3.14159
) eggs
will still be bound to "green"
.
When a for-loop executes, it takes the name you give it, and binds it in turn to each object in the iterable while running the loop; when you call a function, it takes the names in the function header and binds them to the arguments passed; reassigning a name is actually rebinding a name (it can take a while to absorb this -- it did for me, anyway).
With for-loops utilizing lists, there are two basic ways to assign back to the list:
for i, item in enumerate(some_list):
some_list[i] = process(item)
or
new_list = []
for item in some_list:
new_list.append(process(item))
some_list[:] = new_list
Notice the [:]
on that last some_list
-- it is causing a mutation of some_list
's elements (setting the entire thing to new_list
's elements) instead of rebinding the name some_list
to new_list
. Is this important? It depends! If you have other names besides some_list
bound to the same list object, and you want them to see the updates, then you need to use the slicing method; if you don't, or if you do not want them to see the updates, then rebind -- some_list = new_list
.
While a set
may be what you want structure-wise, the question is what is faster. A list is faster. Your example code doesn't accurately compare set
vs list
because you're converting from a list to a set in set_loop
, and then you're creating the list
you'll be looping through in list_loop
. The set and list you iterate through should be constructed and in memory ahead of time, and simply looped through to see which data structure is faster at iterating:
ids_list = range(1000000)
ids_set = set(ids)
def f(x):
for i in x:
pass
%timeit f(ids_set)
#1 loops, best of 3: 214 ms per loop
%timeit f(ids_list)
#1 loops, best of 3: 176 ms per loop
If removing empty lines means lines including any spaces, use:
grep '\S' FILE
For example:
$ printf "line1\n\nline2\n \nline3\n\t\nline4\n" > FILE
$ cat -v FILE
line1
line2
line3
line4
$ grep '\S' FILE
line1
line2
line3
line4
$ grep . FILE
line1
line2
line3
line4

Based on @lijat, here is a simplified implementation. In my spring-based application I simply load this as a bean.
public static void configureLog4jFromSystemProperties()
{
final String LOGGER_PREFIX = "log4j.logger.";
for(String propertyName : System.getProperties().stringPropertyNames())
{
if (propertyName.startsWith(LOGGER_PREFIX)) {
String loggerName = propertyName.substring(LOGGER_PREFIX.length());
String levelName = System.getProperty(propertyName, "");
Level level = Level.toLevel(levelName); // defaults to DEBUG
if (!"".equals(levelName) && !levelName.toUpperCase().equals(level.toString())) {
logger.error("Skipping unrecognized log4j log level " + levelName + ": -D" + propertyName + "=" + levelName);
continue;
}
logger.info("Setting " + loggerName + " => " + level.toString());
Logger.getLogger(loggerName).setLevel(level);

OK, guys, here's my little test too. I had a similar problem, so I decided to test out 3 situations:
All the results were as expected.
Instead of browsing tutorials, I found it easier to try it out, so I did. My conclusion: whenever you include an external JS file in your HTML page, the contents of the external JS gets "copy/pasted" into your HTML page before the page is rendered. Or into your PHP page if you will. Please correct me if I'm wrong here. Thanx.
My example files follow:
EXTERNAL JS:
var global = 0;
function f1()
{
alert('fired: f1');
global = 1;
alert('global changed to 1');
}
function f2()
{
alert('fired f2');
alert('value of global: '+global);
}

You probably want ANSI color codes. Most *nix terminals support them.
Write a new class that holds all the values that you need and use the new class's object as the value in your HashMap
HashMap<String, MyObject>
class MyObject {
public String value1;
public int value2;
public List<String> value3;
}
Use .lower()
- For example:
s = "Kilometer"
print(s.lower())
The official 2.x documentation is here: str.lower()
The official 3.x documentation is here: str.lower()
this can be done very easily with HTML 5, see this link http://www.html5rocks.com/en/tutorials/file/dndfiles/
According to the jQuery documentation, shorthand CSS properties are not supported.
Depending on what you mean by "total padding", you may be able to do something like this:
var $img = $('img');
var paddT = $img.css('padding-top') + ' ' + $img.css('padding-right') + ' ' + $img.css('padding-bottom') + ' ' + $img.css('padding-left');
If ALTER COLUMN doesn't work.
It is not unusual for alter column to fail because it cannot make the transformation you desire. In this case, the solution is to create a dummy table TableName_tmp, copy the data over with your specialized transformation in the bulk Insert command, drop the original table, and rename the tmp table to the original table's name. You'll have to drop and recreate the Foreign key constraints and, for performance, you'll probably want to create keys after filling the tmp table.
Sound like a lot of work? Actually, it isn't.
If you are using SQL Server, you can make the SQL Server Management Studio do the work for you!
Well just a small change 'cause the above solution outputs
"I want anapple"
instead of
"I want an apple"
To get the output as
"I want an apple"
use the following modified code
var output = a.substr(0, position) + " " + b + a.substr(position);
For any non-trivial application (I.E. the application must receive and handle different kinds of messages with different lengths), the solution to your particular problem isn't necessarily just a programming solution - it's a convention, I.E. a protocol.
In order to determine how many bytes you should pass to your read
call, you should establish a common prefix, or header, that your application receives. That way, when a socket first has reads available, you can make decisions about what to expect.
A binary example might look like this:
#include <stdint.h>
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <arpa/inet.h>
enum MessageType {
MESSAGE_FOO,
MESSAGE_BAR,
};
struct MessageHeader {
uint32_t type;
uint32_t length;
};
/**
* Attempts to continue reading a `socket` until `bytes` number
* of bytes are read. Returns truthy on success, falsy on failure.
*
* Similar to @grieve's ReadXBytes.
*/
int readExpected(int socket, void *destination, size_t bytes)
{
/*
* Can't increment a void pointer, as incrementing
* is done by the width of the pointed-to type -
* and void doesn't have a width
*
* You can in GCC but it's not very portable
*/
char *destinationBytes = destination;
while (bytes) {
ssize_t readBytes = read(socket, destinationBytes, bytes);
if (readBytes < 1)
return 0;
destinationBytes += readBytes;
bytes -= readBytes;
}
return 1;
}
int main(int argc, char **argv)
{
int selectedFd;
// use `select` or `poll` to wait on sockets
// received a message on `selectedFd`, start reading
char *fooMessage;
struct {
uint32_t a;
uint32_t b;
} barMessage;
struct MessageHeader received;
if (!readExpected (selectedFd, &received, sizeof(received))) {
// handle error
}
// handle network/host byte order differences maybe
received.type = ntohl(received.type);
received.length = ntohl(received.length);
switch (received.type) {
case MESSAGE_FOO:
// "foo" sends an ASCII string or something
fooMessage = calloc(received.length + 1, 1);
if (readExpected (selectedFd, fooMessage, received.length))
puts(fooMessage);
free(fooMessage);
break;
case MESSAGE_BAR:
// "bar" sends a message of a fixed size
if (readExpected (selectedFd, &barMessage, sizeof(barMessage))) {
barMessage.a = ntohl(barMessage.a);
barMessage.b = ntohl(barMessage.b);
printf("a + b = %d\n", barMessage.a + barMessage.b);
}
break;
default:
puts("Malformed type received");
// kick the client out probably
}
}
You can likely already see one disadvantage of using a binary format - for each attribute greater than a char
you read, you will have to ensure its byte order is correct using the ntohl
or ntohs
functions.
An alternative is to use byte-encoded messages, such as simple ASCII or UTF-8 strings, which avoid byte-order issues entirely but require extra effort to parse and validate.
There are two final considerations for network data in C.
The first is that some C types do not have fixed widths. For example, the humble int
is defined as the word size of the processor, so 32 bit processors will produce 32 bit int
s, while 64 bit processors will produces 64 bit int
s. Good, portable code should have network data use fixed-width types, like those defined in stdint.h
.
The second is struct padding. A struct with different-widthed members will add data in between some members to maintain memory alignment, making the struct faster to use in the program but sometimes producing confusing results.
#include <stdio.h>
#include <stdint.h>
int main()
{
struct A {
char a;
uint32_t b;
} A;
printf("sizeof(A): %ld\n", sizeof(A));
}
In this example, its actual width won't be 1 char
+ 4 uint32_t
= 5 bytes, it'll be 8:
mharrison@mharrison-KATANA:~$ gcc -o padding padding.c
mharrison@mharrison-KATANA:~$ ./padding
sizeof(A): 8
This is because 3 bytes are added after char a
to make sure uint32_t b
is memory-aligned.
So if you write
a struct A
, then attempt to read a char
and a uint32_t
on the other side, you'll get char a
, and a uint32_t where the first three bytes are garbage and the last byte is the first byte of the actual integer you wrote.
Either document your data format explicitly as C struct types or, better yet, document any padding bytes they might contain.

There are 4 dimensions of the tensor you want to convert.
[:, ::-1, :, :]
:
means that the first dimension should be copied as it is and converted, same goes for the third and fourth dimension.
::-1
means that for the second axes it reverses the the axes

::-----------------------------------------------------------------------------
:: Description : Sets or clears a group of environment variables containing
:: : components of the current date extracted from the string
:: : returned by the DATE /T command. These variables can be
:: : used to name files, control the flow of execution, etc.
:: :
:: Requires : Windows NT with command extensions enabled
:: :
:: Tested : Yes, as demonstration
:: :
:: Contact : Brett Middleton <[email protected]>
:: : Animal and Dairy Science Department
:: : University of Georgia, Athens
::-----------------------------------------------------------------------------
:: USAGE
::
:: SetEnvDate1 can be used as a model for coding date/time routines in
:: other scripts, or can be used by itself as a utility that is called
:: from other scripts.
::
:: Run or call SetEnvDate1 without arguments to set the date variables.
:: Variables are set for the day abbreviation (DT_DAY), month number (DT_MM),
:: day number (DT_DD) and four-digit year (DT_YYYY).
::
:: When the variables are no longer needed, clean up the environment by
:: calling the script again with the CLEAR argument. E.g.,
::
:: call SetEnvDate1 clear
::-----------------------------------------------------------------------------
:: NOTES
::
:: A time variable could be added by parsing the string returned by the
:: built-in TIME /T command. This is left as an exercise for the reader. B-)
::
:: This script illustrates the following NT command extensions:
::
:: 1. Use of the extended IF command to do case-insensitive comparisons.
::
:: 2. Use of the extended DATE command.
::
:: 3. Use of the extended FOR command to parse a string returned by a
:: command or program.
::
:: 4. Use of the "()" conditional processing symbols to group commands
:: for conditional execution. All commands between the parens will
:: be executed if the preceeding IF or FOR statement is TRUE.

It's easy maybe you have error in the configuration.
For Example: Manifest.xml
But in my configuration have for default Activity .Splash
you need check this configuration and the file Manifest.xml
Good Luck
I was thundered when the following code worked.
import os
for file in os.listdir("../FutureBookList"):
if file.endswith(".adoc"):
filename, file_extension = os.path.splitext(file)
print(filename)
print(file_extension)
continue
else:
continue
So, I checked the documentation and it says:
Changed in version 3.6: Accepts a path-like object.
An object representing a file system path. A path-like object is either a str or...
I did a little more digging and the following also works:
with open("../FutureBookList/file.txt") as file:
data = file.read()
I was just struggling with same situation. Following solved the issue:
If you have directory structure like this:
folders:
- map: /Users/me/code/exampleproject
to: /home/vagrant/code/exampleproject
Just create 'public' folder within exampleproject on your host machine.
Far from bad practice, Python (and other languages?) extended the for
loop structure so part of it will only be executed if the loop doesn't break
.
for n in range(5):
for m in range(3):
if m >= n:
print('stop!')
break
print(m, end=' ')
else:
print('finished.')
Output:
stop!
0 stop!
0 1 stop!
0 1 2 finished.
0 1 2 finished.
Equivalent code without break
and that handy else
:
for n in range(5):
aborted = False
for m in range(3):
if not aborted:
if m >= n:
print('stop!')
aborted = True
else:
print(m, end=' ')
if not aborted:
print('finished.')
The one liner : bind()
to own address, connect()
to remote address.
Quoting from the man page of bind()
bind() assigns the address specified by addr to the socket referred to by the file descriptor sockfd. addrlen specifies the size, in bytes, of the address structure pointed to by addr. Traditionally, this operation is called "assigning a name to a socket".
and, from the same for connect()
The connect() system call connects the socket referred to by the file descriptor sockfd to the address specified by addr.
To clarify,
bind()
associates the socket with its local address [that's why
server side bind
s, so that clients can use that address to connect
to server.]connect()
is used to connect to a remote [server] address, that's
why is client side, connect [read as: connect to server] is used.One possible solution might be setting a flag while showing the system-dialog and then in the onStop method of the activity life-cycle, check for the flag, if true, finish the activity.
For example, if the system dialog is triggered by some buttonclick, then the onclick listener might be like
private OnClickListener btnClickListener = new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setType("text/plain");
CheckActivity.this.startActivity(Intent.createChooser(intent, "Complete action using"));
checkFlag = true; //flag used to check
}
};
and in onstop of activity:
@Override
protected void onStop() {
if(checkFlag){
finish();
}
super.onStop();
}
memory mapping is not only used to map files into memory but is also a tool to request RAM from kernel. These are those inode 0 entries - your stack, heap, bss segments and more
Here is a method that uses stamper and absolute coordinates showed in the different PDF clients (Adobe, FoxIt and etc. )
public static void AddTextToPdf(string inputPdfPath, string outputPdfPath, string textToAdd, System.Drawing.Point point)
{
//variables
string pathin = inputPdfPath;
string pathout = outputPdfPath;
//create PdfReader object to read from the existing document
using (PdfReader reader = new PdfReader(pathin))
//create PdfStamper object to write to get the pages from reader
using (PdfStamper stamper = new PdfStamper(reader, new FileStream(pathout, FileMode.Create)))
{
//select two pages from the original document
reader.SelectPages("1-2");
//gettins the page size in order to substract from the iTextSharp coordinates
var pageSize = reader.GetPageSize(1);
// PdfContentByte from stamper to add content to the pages over the original content
PdfContentByte pbover = stamper.GetOverContent(1);
//add content to the page using ColumnText
Font font = new Font();
font.Size = 45;
//setting up the X and Y coordinates of the document
int x = point.X;
int y = point.Y;
y = (int) (pageSize.Height - y);
ColumnText.ShowTextAligned(pbover, Element.ALIGN_CENTER, new Phrase(textToAdd, font), x, y, 0);
}
}
Arrays can only be passed by reference, actually:
void foo(double (&bar)[10])
{
}
This prevents you from doing things like:
double arr[20];
foo(arr); // won't compile
To be able to pass an arbitrary size array to foo
, make it a template and capture the size of the array at compile time:
template<typename T, size_t N>
void foo(T (&bar)[N])
{
// use N here
}
You should seriously consider using std::vector
, or if you have a compiler that supports c++11, std::array
.
