Other workarounds include using SELECT DISTINCT or LIMIT in the subquery, although these are not as explicit in their effect on materialization. this worked for me
I think, from your description, the following would suffice:
DELETE FROM guide_category
WHERE id_guide NOT IN (SELECT id_guide FROM guide)
I assume, that there are no referential integrity constraints on the tables involved, are there?
As far as concerns, you want to delete rows in story_category
that do not exist in category
.
Here is your original query to identify the rows to delete:
SELECT *
FROM story_category
WHERE category_id NOT IN (
SELECT DISTINCT category.id
FROM category INNER JOIN
story_category ON category_id=category.id
);
Combining NOT IN
with a subquery that JOIN
s the original table seems unecessarily convoluted. This can be expressed in a more straight-forward manner with not exists
and a correlated subquery:
select sc.*
from story_category sc
where not exists (select 1 from category c where c.id = sc.category_id);
Now it is easy to turn this to a delete
statement:
delete from story_category
where not exists (select 1 from category c where c.id = story_category.category_id);
This quer would run on any MySQL version, as well as in most other databases that I know.
-- set-up
create table story_category(category_id int);
create table category (id int);
insert into story_category values (1), (2), (3), (4), (5);
insert into category values (4), (5), (6), (7);
-- your original query to identify offending rows
SELECT *
FROM story_category
WHERE category_id NOT IN (
SELECT DISTINCT category.id
FROM category INNER JOIN
story_category ON category_id=category.id);
| category_id | | ----------: | | 1 | | 2 | | 3 |
-- a functionally-equivalent, simpler query for this
select sc.*
from story_category sc
where not exists (select 1 from category c where c.id = sc.category_id)
| category_id | | ----------: | | 1 | | 2 | | 3 |
-- the delete query
delete from story_category
where not exists (select 1 from category c where c.id = story_category.category_id);
-- outcome
select * from story_category;
| category_id | | ----------: | | 4 | | 5 |
UPDATE user_account
SET (student_education_facility_id) = (
SELECT teacher.education_facility_id
FROM user_account teacher
WHERE teacher.user_account_id = teacher_id
AND teacher.user_type = 'ROLE_TEACHER'
)
WHERE user_type = 'ROLE_STUDENT'
Above are the sample update query...
You can write sub query with update SQL statement, you don't need to give alias name for that table. give alias name to sub query table. I tried and it's working fine for me....
We declare a variable 'a'
SET **@a** = (SELECT MAX( customer_id ) FROM customers) +1;
INSERT INTO customers
( customer_id, firstname, surname )
VALUES
(**@a**, 'jim', 'sock')
TextView pf = new TextView(context);
pf.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
For different layouts like ConstraintLayout
and others, they have their own LayoutParams
, like so:
pf.setLayoutParams(new ConstraintLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
or
parentView.addView(pf, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
Third times the charm. My guess is that this is a bug and Zhenya's answer suggests it's fixed in the latest version. I have version 0.99.1.1 and I've created the following solution:
import matplotlib.pyplot as plt
import numpy as np
def forceAspect(ax,aspect=1):
im = ax.get_images()
extent = im[0].get_extent()
ax.set_aspect(abs((extent[1]-extent[0])/(extent[3]-extent[2]))/aspect)
data = np.random.rand(10,20)
fig = plt.figure()
ax = fig.add_subplot(111)
ax.imshow(data)
ax.set_xlabel('xlabel')
ax.set_aspect(2)
fig.savefig('equal.png')
ax.set_aspect('auto')
fig.savefig('auto.png')
forceAspect(ax,aspect=1)
fig.savefig('force.png')
This is 'force.png':
Below are my unsuccessful, yet hopefully informative attempts.
Second Answer:
My 'original answer' below is overkill, as it does something similar to axes.set_aspect()
. I think you want to use axes.set_aspect('auto')
. I don't understand why this is the case, but it produces a square image plot for me, for example this script:
import matplotlib.pyplot as plt
import numpy as np
data = np.random.rand(10,20)
fig = plt.figure()
ax = fig.add_subplot(111)
ax.imshow(data)
ax.set_aspect('equal')
fig.savefig('equal.png')
ax.set_aspect('auto')
fig.savefig('auto.png')
Produces an image plot with 'equal' aspect ratio: and one with 'auto' aspect ratio:
The code provided below in the 'original answer' provides a starting off point for an explicitly controlled aspect ratio, but it seems to be ignored once an imshow is called.
Original Answer:
Here's an example of a routine that will adjust the subplot parameters so that you get the desired aspect ratio:
import matplotlib.pyplot as plt
def adjustFigAspect(fig,aspect=1):
'''
Adjust the subplot parameters so that the figure has the correct
aspect ratio.
'''
xsize,ysize = fig.get_size_inches()
minsize = min(xsize,ysize)
xlim = .4*minsize/xsize
ylim = .4*minsize/ysize
if aspect < 1:
xlim *= aspect
else:
ylim /= aspect
fig.subplots_adjust(left=.5-xlim,
right=.5+xlim,
bottom=.5-ylim,
top=.5+ylim)
fig = plt.figure()
adjustFigAspect(fig,aspect=.5)
ax = fig.add_subplot(111)
ax.plot(range(10),range(10))
fig.savefig('axAspect.png')
This produces a figure like so:
I can imagine if your having multiple subplots within the figure, you would want to include the number of y and x subplots as keyword parameters (defaulting to 1 each) to the routine provided. Then using those numbers and the hspace
and wspace
keywords, you can make all the subplots have the correct aspect ratio.
string t = DateTime.Now.ToString("h/m/s tt");
string t2 = DateTime.Now.ToString("hh:mm:ss tt");
string d = DateTime.Now.ToString("MM/dd/yy");
Here's an improved/combined version of Lee's, Oliver's and Stephan's answers.
public delegate void InvokeIfRequiredDelegate<T>(T obj)
where T : ISynchronizeInvoke;
public static void InvokeIfRequired<T>(this T obj, InvokeIfRequiredDelegate<T> action)
where T : ISynchronizeInvoke
{
if (obj.InvokeRequired)
{
obj.Invoke(action, new object[] { obj });
}
else
{
action(obj);
}
}
The template allows for flexible and cast-less code which is much more readable while the dedicated delegate provides efficiency.
progressBar1.InvokeIfRequired(o =>
{
o.Style = ProgressBarStyle.Marquee;
o.MarqueeAnimationSpeed = 40;
});
It is just a hint for the Service Provider on what to expect from the NameID returned by the Identity Provider. It can be:

WindowsDomainQualifiedName
– e.g. CompanyDomain\John
kerberos
– e.g. john@realm
entity
– this one in used to identify entities that provide SAML-based services and looks like a URIpersistent
– this is an opaque service-specific identifier which must include a pseudo-random value and must not be traceable to the actual user, so this is a privacy feature.transient
– opaque identifier which should be treated as temporary.As mentioned in other answers, doubles can have small deviations. And you could write your own method to compare them using an "acceptable" deviation. However ...
There is an apache class for comparing doubles: org.apache.commons.math3.util.Precision
It contains some interesting constants: SAFE_MIN
and EPSILON
, which are the maximum possible deviations of simple arithmetic operations.
It also provides the necessary methods to compare, equal or round doubles. (using ulps or absolute deviation)

Bootstrap now has the following style for table cells:
.table tbody > tr > td{
vertical-align: top;
}
The way to go is to add your own class, adding more specificity to the previous selector:
.table tbody > tr > td.vert-aligned {
vertical-align: middle;
}
And then add the class to your td
s:
<tr>
<td class="vert-aligned"></td>
...
</tr>
There is no way to do this with Bootstrap.
When used in table cells, vertical-align does what most people expect it to, which is to mimic the (old, deprecated) valign attribute. In a modern, standards-compliant browser, the following three code snippets do the same thing:
<td valign="middle"> <!-- but you shouldn't ever use valign --> </td>
<td style="vertical-align:middle"> ... </td>
<div style="display:table-cell; vertical-align:middle"> ... </div>
Check your fiddle updated
Also, you can't refer to the td
class using .vert
because Bootstrap already has this class:
.table td {
padding: 8px;
line-height: 20px;
text-align: left;
vertical-align: top; // The problem!
border-top: 1px solid #dddddd;
}
And is overloading the vertical-align: middle
in '.vert' class, so you have to define this class as td.vert
.
In python there is no difference between modules and scripts; You can execute both scripts and modules. The file must be on the pythonpath AFAIK because python must be able to find the file in question. If python is executed from a directory, then the directory is automatically added to the pythonpath.
Refer to What is the best way to call a Python script from another Python script? for more information about modules vs scripts
There is also a builtin function execfile(filename) that will do what you want
Try conda install graphviz
. I had the same problem, I resolved it by mentioned command in MacOS.
If you are using ATL/MFC CString
, simply call CString::MakeReverse()
.
HTTP and HTTPS:
const getScript = (url) => {
return new Promise((resolve, reject) => {
const http = require('http'),
https = require('https');
let client = http;
if (url.toString().indexOf("https") === 0) {
client = https;
}
client.get(url, (resp) => {
let data = '';
// A chunk of data has been recieved.
resp.on('data', (chunk) => {
data += chunk;
});
// The whole response has been received. Print out the result.
resp.on('end', () => {
resolve(data);
});
}).on("error", (err) => {
reject(err);
});
});
};
(async (url) => {
console.log(await getScript(url));
})('https://sidanmor.com/');

The simplest solution for a contains
function, would be a function that looks like this :
var contains = function (haystack, needle) {
return !!~haystack.indexOf(needle);
}
Ideally, you wouldn't make this a stand-alone function, though, but part of a helper library :
var helper = {};
helper.array = {
contains : function (haystack, needle) {
return !!~haystack.indexOf(needle);
},
...
};
Now, if you happen to be one of those unlucky people who still needs to support IE<9 and thus can't rely on indexOf
, you could use this polyfill, which I got from the MDN :
if (!Array.prototype.indexOf) {
Array.prototype.indexOf = function(searchElement, fromIndex) {
var k;
if (this == null) {
throw new TypeError('"this" is null or not defined');
}
var o = Object(this);
var len = o.length >>> 0;
if (len === 0) {
return -1;
}
var n = +fromIndex || 0;
if (Math.abs(n) === Infinity) {
n = 0;
}
if (n >= len) {
return -1;
}
k = Math.max(n >= 0 ? n : len - Math.abs(n), 0);
while (k < len) {
if (k in o && o[k] === searchElement) {
return k;
}
k++;
}
return -1;
};
}
This is another thread pool implementation that is very simple, easy to understand and use, uses only C++11 standard library, and can be looked at or modified for your uses, should be a nice starter if you want to get into using thread pools:
Use
// aspect-type.js
class AspectType {
}
export default AspectType;
Then to import it
// some-other-file.js
import AspectType from './aspect-type';

I was having the same problem, none of the posted solutions helped. Finally, I figured out what I was doing wrong. When I installed the Java JDK it asked me for a directiy where I wanted to install. I changed the directory to where I wanted the code to go. It then asked for a directory where it could install the Runtime Environment and I selected the SAME DIRECTORY where I installed the JDK. It over wrote my lib folder and erased the tools.jar. Be sure to use different folders during the install. I used my custom folder for the JDK and the default folder for the RE and everything worked fine.
None of the following answers are right. All these methods just seem to be alike, but in practice do absolutely different things. It is hard to give short comments. Better to give a link to full documentation about these methods: http://docs.jboss.org/hibernate/core/3.6/reference/en-US/html/objectstate.html
A programmatically solution will be:

textView.setText("No result found");
listView.setEmptyView(textView);

You can also assign a new value to a tf.Variable
without adding an operation to the graph: tf.Variable.load(value, session)
. This function can also save you adding placeholders when assigning a value from outside the graph and it is useful in case the graph is finalized.
import tensorflow as tf
x = tf.Variable(0)
sess = tf.Session()
sess.run(tf.global_variables_initializer())
print(sess.run(x)) # Prints 0.
x.load(1, sess)
print(sess.run(x)) # Prints 1.
Update: This is depricated in TF2 as eager execution is default and graphs are no longer exposed in the user-facing API.

If you want to export all JAR-files of a Java web-project, open the latest generated WAR-file with a ZIP-tool (e.g. 7-Zip), navigate to the /WEB-INF/lib/ folder. Here you will find all JAR-files you need for this project (as listed in "Referenced Libraries").
When the program that opened the port exits, the port will be closed automatically. If you kill the Java process running this server, that should do it.
I closed modal Programmatically with this trick
Add a button in modal with data-dismiss="modal"
and hide the button with display: none
. Here is how it will look like
<div class="modal fade" id="addNewPaymentMethod" role="dialog">
<div class="modal-dialog">
.
.
.
<button type="button" id="close-modal" data-dismiss="modal" style="display: none">Close</button>
</div>
</div>
Now when you want to close modal Programmatically just trigger a click event on that button, which is not visible to user
In Javascript you can trigger click on that button like this:
document.getElementById('close-modal').click();
I've read numerous forums and tried play apps but not found a solution until now.
My scenario I believe is similar to yours, but I will clarify to help others. I have a locally hosted website and web services to be used by my android application. I need to have this working on the road for demonstration with only my laptop and no network connection.
Note: Using my iPhone as a wifi hotspot and connecting both my pc and my android device worked, but the iPhone 4S connection is slow and dropped out regularly.
My solution is as follows:

The SqlException has a Number property that you can check. For duplicate error the number is 2601.
catch (SqlException e)
{
switch (e.Number)
{
case 2601:
// Do something.
break;
default:
throw;
}
}
To get a list of all SQL errors from you server, try this:
SELECT * FROM sysmessages
Update
This can now be simplified in C# 6.0
catch (SqlException e) when (e.Number == 2601)
{
// Do something.
}
boolean is a primitive data type in Java and primitive data types can not be null like other primitives int, float etc, they should be containing default values if not assigned.
In Java, only objects can assigned to null, it means the corresponding object has no reference and so does not contain any representation in memory.
Hence If you want to work with object as null , you should be using Boolean class which wraps a primitive boolean type value inside its object.
These are called wrapper classes in Java
For Example:
Boolean bool = readValue(...); // Read Your Value
if (bool == null) { do This ...}
If you are using ajax then (making it as simple as possible)
Add your loading gif image to html and make it hidden (using style in html itself now, you can add it to separate CSS):
<img src="path\to\loading\gif" id="img" style="display:none"/ >
Show the image when button is clicked and hide it again on success function
$('#buttonID').click(function(){
$('#img').show(); //<----here
$.ajax({
....
success:function(result){
$('#img').hide(); //<--- hide again
}
}
Make sure you hide the image on ajax error callbacks too to make sure the gif hides even if the ajax fails.
Here's a generalized version I came up with off the top of my head, for swapping a value in place. The other suggestions would be better if performance is a problem.
template<typename T>
void ByteSwap(T * p)
{
for (int i = 0; i < sizeof(T)/2; ++i)
std::swap(((char *)p)[i], ((char *)p)[sizeof(T)-1-i]);
}
Disclaimer: I haven't tried to compile this or test it yet.
You could use preg_split
instead of explode
and split on [ ]+
(one or more spaces). But I think in this case you could go with preg_match_all
and capturing:
preg_match_all('/[ ]php[ ]+\S+[ ]+(\S+)/', $input, $matches);
$result = $matches[1];
The pattern matches a space, php
, more spaces, a string of non-spaces (the path), more spaces, and then captures the next string of non-spaces. The first space is mostly to ensure that you don't match php
as part of a user name but really only as a command.
An alternative to capturing is the "keep" feature of PCRE. If you use \K
in the pattern, everything before it is discarded in the match:
preg_match_all('/[ ]php[ ]+\S+[ ]+\K\S+/', $input, $matches);
$result = $matches[0];
I would use preg_match()
. I do something similar for many of my system management scripts. Here is an example:
$test = "user 12052 0.2 0.1 137184 13056 ? Ss 10:00 0:00 php /home/user/public_html/utilities/runProcFile.php cust1 cron
user 12054 0.2 0.1 137184 13064 ? Ss 10:00 0:00 php /home/user/public_html/utilities/runProcFile.php cust3 cron
user 12055 0.6 0.1 137844 14220 ? Ss 10:00 0:00 php /home/user/public_html/utilities/runProcFile.php cust4 cron

root 12070 0.0 0.0 103240 828 pts/1 R+ 10:00 0:00 grep utilities";
$lines = explode("\n", $test);
foreach($lines as $line){
if(preg_match("/.php[\s+](cust[\d]+)[\s+]cron/i", $line, $matches)){
print_r($matches);
}
}
The above prints:
Array
(
[0] => .php cust1 cron
[1] => cust1
)
Array
(
[0] => .php cust3 cron
[1] => cust3
)
Array
(
[0] => .php cust4 cron
[1] => cust4
)
Array
(
[0] => .php cust89 cron
[1] => cust89
)
Array
(
[0] => .php cust435 cron
[1] => cust435
)
Array
(
[0] => .php cust16 cron
[1] => cust16
)
You can set $test
to equal the output from exec. the values you are looking for would be in the if
statement under the foreach
. $matches[1]
will have the custx value.
Was having the same error and fixing the credentials in the IIS app pool did not help. I finally resolved the error in IIS by selecting my website under Default Web Site, Advanced Settings->Physical Path Credentials->Specific User, and reentered the credentials for the app pool user, then restarted IIS and the error went away and my website came up successfully.
A view model
represents the data that you want to display on your view/page, whether it be used for static text or for input values (like textboxes and dropdown lists) that can be added to the database (or edited). It is something different than your domain model
. It is a model for the view.
Let us say that you have an Employee
class that represents your employee domain model and it contains the following properties (unique identifier, first name, last name and date created):
public class Employee : IEntity
{
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public DateTime DateCreated { get; set; }
}
View models differ from domain models in that view models only contain the data (represented by properties) that you want to use on your view. For example, lets say that you want to add a new employee record, your view model might look like this:
public class CreateEmployeeViewModel
{
public string FirstName { get; set; }
public string LastName { get; set; }
}
As you can see it only contains two of the properties. These two properties are also in the employee domain model. Why is this you may ask? Id
might not be set from the view, it might be auto generated by the Employee table. And DateCreated
might also be set in the stored procedure or in the service layer of your application. So Id
and DateCreated
are not needed in the view model. You might want to display these two properties when you view an employee’s details (an employee that has already been captured) as static text.
When loading the view/page, the create action method in your employee controller will create an instance of this view model, populate any fields if required, and then pass this view model to the view/page:
public class EmployeeController : Controller
{
private readonly IEmployeeService employeeService;
public EmployeeController(IEmployeeService employeeService)
{
this.employeeService = employeeService;
}
public ActionResult Create()
{
CreateEmployeeViewModel model = new CreateEmployeeViewModel();
return View(model);
}
public ActionResult Create(CreateEmployeeViewModel model)
{
// Do what ever needs to be done before adding the employee to the database
}
}
Your view/page might look like this (assuming you are using ASP.NET MVC
and the Razor
view engine):
@model MyProject.Web.ViewModels.CreateEmployeeViewModel
<table>
<tr>
<td><b>First Name:</b></td>
<td>@Html.TextBoxFor(m => m.FirstName, new { maxlength = "50", size = "50" })
@Html.ValidationMessageFor(m => m.FirstName)
</td>
</tr>
<tr>
<td><b>Last Name:</b></td>
<td>@Html.TextBoxFor(m => m.LastName, new { maxlength = "50", size = "50" })
@Html.ValidationMessageFor(m => m.LastName)
</td>
</tr>
</table>
Validation would thus be done only on FirstName
and LastName
. Using FluentValidation you might have validation like this:
public class CreateEmployeeViewModelValidator : AbstractValidator<CreateEmployeeViewModel>
{
public CreateEmployeeViewModelValidator()
{
RuleFor(m => m.FirstName)
.NotEmpty()
.WithMessage("First name required")
.Length(1, 50)
.WithMessage("First name must not be greater than 50 characters");
RuleFor(m => m.LastName)
.NotEmpty()
.WithMessage("Last name required")
.Length(1, 50)
.WithMessage("Last name must not be greater than 50 characters");
}
}
And with Data Annotations it might look this:
public class CreateEmployeeViewModel : ViewModelBase
{
[Display(Name = "First Name")]
[Required(ErrorMessage = "First name required")]
public string FirstName { get; set; }
[Display(Name = "Last Name")]
[Required(ErrorMessage = "Last name required")]
public string LastName { get; set; }
}
The key thing to remember is that the view model only represents the data that you want to use, nothing else. You can imagine all the unnecessary code and validation if you have a domain model with 30 properties and you only want to update a single value. Given this scenario you would only have this one value/property in the view model and not all the properties that are in the domain object.
A view model might not only have data from one database table. It can combine data from another table. Take my example above about adding a new employee record. Besides adding just the first and last names you might also want to add the department of the employee. This list of departments will come from your Departments
table. So now you have data from the Employees
and Departments
tables in one view model. You will just then need to add the following two properties to your view model and populate it with data:
public int DepartmentId { get; set; }
public IEnumerable<Department> Departments { get; set; }
When editing employee data (an employee that has already been added to the database) it wouldn’t differ much from my example above. Create a view model, call it for example EditEmployeeViewModel
. Only have the data that you want to edit in this view model, like first name and last name. Edit the data and click the submit button. I wouldn’t worry too much about the Id
field because the Id
value will probably been in the URL, for example:
http://www.yourwebsite.com/Employee/Edit/3
Take this Id
and pass it through to your repository layer, together with your first name and last name values.
When deleting a record, I normally follow the same path as with the edit view model. I would also have a URL, for example:
http://www.yourwebsite.com/Employee/Delete/3
When the view loads up for the first time I would get the employee’s data from the database using the Id
of 3. I would then just display static text on my view/page so that the user can see what employee is being deleted. When the user clicks the Delete button, I would just use the Id
value of 3 and pass it to my repository layer. You only need the Id
to delete a record from the table.
Another point, you don’t really need a view model for every action. If it is simple data then it would be fine to only use EmployeeViewModel
. If it is complex views/pages and they differ from each other then I would suggest you use separate view models for each.
I hope this clears up any confusion that you had about view models and domain models.
You need the ip of the other pc and do:

Try sprintf():

int num = 3;
sprintf(str, "%d", num); // str now contains "3"
sprintf() is like printf() but outputs to a string.
Also, as Parappa mentioned in the comments, you might want to use snprintf() to stop a buffer overflow from occuring (where the number you're converting doesn't fit the size of your string.) It works like this:
snprintf(str, sizeof(str), "%d", num);
It is not possible to save file locally without involving the local client (browser machine) as I could be a great threat to client machine. You can use link to download that file. If you want to store something like Json data on local machine you can use LocalStorage provided by the browsers, Web Storage

Edit (2020.12.28): GitHub change default master branch to main branch since October 2020. See https://github.com/github/renaming
Update March 2013
Git 1.8.2 added the possibility to track branches.
"
git submodule
" started learning a new mode to integrate with the tip of the remote branch (as opposed to integrating with the commit recorded in the superproject's gitlink).
# add submodule to track master branch
git submodule add -b master [URL to Git repo];
# update your submodule
git submodule update --remote
If you had a submodule already present you now wish would track a branch, see "how to make an existing submodule track a branch".
Also see Vogella's tutorial on submodules for general information on submodules.
Note:
git submodule add -b . [URL to Git repo];
^^^
A special value of
.
is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.
See commit b928922727d6691a3bdc28160f93f25712c565f6:
submodule add
: If --branch
is given, record it in .gitmodules
This allows you to easily record a
submodule.<name>.branch
option in.gitmodules
when you add a new submodule. With this patch,
$ git submodule add -b <branch> <repository> [<path>]
$ git config -f .gitmodules submodule.<path>.branch <branch>
reduces to
$ git submodule add -b <branch> <repository> [<path>]
This means that future calls to
$ git submodule update --remote ...
will get updates from the same branch that you used to initialize the submodule, which is usually what you want.

Original answer (February 2012):
A submodule is a single commit referenced by a parent repo.
Since it is a Git repo on its own, the "history of all commits" is accessible through a git log
within that submodule.
So for a parent to track automatically the latest commit of a given branch of a submodule, it would need to:
gitslave (that you already looked at) seems to be the best fit, including for the commit operation.
It is a little annoying to make changes to the submodule due to the requirement to check out onto the correct submodule branch, make the change, commit, and then go into the superproject and commit the commit (or at least record the new location of the submodule).
Other alternatives are detailed here.
For oracle you can
group by trunc(created);
as this truncates the created datetime to the previous midnight.
Another option is to
group by to_char(created, 'DD.MM.YYYY');
which achieves the same result, but may be slower as it requires a type conversion.
Hi we can use ToLower Method sometimes it is not filter.
EmployeeId = Session["EmployeeID"].ToString();
var rows = dtCrewList.AsEnumerable().Where
(row => row.Field<string>("EmployeeId").ToLower()== EmployeeId.ToLower());
if (rows.Any())
{
tblFiltered = rows.CopyToDataTable<DataRow>();
}
Tables and table cells don't use the min-height
property, setting their height
will be the min-height as tables will expand if the content stretches them.
Or, if you know the width of the two "side" images and don't want to deal with floats:
<div class="container">
<div class="left-panel"><img src="myleftimage" /></div>
<div class="center-panel">Content goes here...</div>
<div class="right-panel"><img src="myrightimage" /></div>
</div>
CSS:
.container {
position:relative;
padding-left:50px;
padding-right:50px;
}
.container .left-panel {
width: 50px;
position:absolute;
left:0px;
top:0px;
}
.container .right-panel {
width: 50px;
position:absolute;
right:0px;
top:0px;
}
.container .center-panel {
background: url('mymiddleimage');
}
Notes:
Position:relative on the parent div is used to make absolutely positioned children position themselves relative to that node.
timeout is a key parameter to this problem.
however it's not suit for me.
i found there is not gunicorn timeout error when i set workers=1.
when i look though my code, i found some socket connect (socket.send & socket.recv) in server init.
socket.recv will block my code and that's why it always timeout when workers>1
hope to give some ideas to the people who have some problem with me
I decided I didn't want to use a pickle because I wanted to be able to open the text file and change its contents easily during testing. Therefore, I did this:
score = [1,2,3,4,5]
with open("file.txt", "w") as f:
for s in score:
f.write(str(s) +"\n")
score = []
with open("file.txt", "r") as f:
for line in f:
score.append(int(line.strip()))
So the items in the file are read as integers, despite being stored to the file as strings.
The exact formula is:
=ArrayFormula(text(A1:A,"00000"))
ArrayFormula works on multiple rows (in the above example, every row), and results are placed in the cell with the formula and the cells below it in the same column. It looks as if the same formula was copied into all those rows.
If any of the cells in that column are not empty, they won't get overwritten. Instead, you will get an error message.
To save yourself typing, you can use the trick from the answer above by pnuts:
Type: =text(A1:A,"00000")
and then hit the following key combination:
On windows: Ctrl
+Shift
+Enter
On a MAC: Command
+Shift
+Enter
This will convert the formula to ArrayFormula.
After hitting the key combination, you need to hit Enter, to actually apply the converted formula.
If your sheet contains header row(s), and you want to apply formula from (for example) row 5 on, you would use =text(A5:A,"00000") instead.
This answer includes information from pnuts's answer and LOAS's comment.
So what I did was to have the standard src/main/resources/application.properties
and also a src/test/resources/application-default.properties
where i override some settings for ALL my tests.
I ran into the same problem and was not using profiles either so far. It seemed to be bothersome to have to do it now and remember declaring the profile -- which can be easily forgotten.
The trick is, to leverage that a profile specific application-<profile>.properties
overrides settings in the general profile. See https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html#boot-features-external-config-profile-specific-properties.
For anyone coming to this topic late, I could see that hitscan's "you probably shouldn't do that" might cause someone to ask what they should do…
The StringBuilder class is often an easy replacement. Consider one of the stream-based classes especially, if your data is coming from a file.
The problem with s += "stuff"
is that it has to allocate a completely new area to hold the data and then copy all of the old data to it plus the new stuff - EACH AND EVERY LOOP ITERATION. So, adding five bytes to 1,000,000 with s += "stuff"
is extremely costly.
If what you want is to just write five bytes to the end and proceed with your program, you have to pick a class that leaves some room for growth:
StringBuilder sb = new StringBuilder(5000);
for (; ; )
{
sb.Append("stuff");
}
StringBuilder
will auto-grow by doubling when it's limit is hit. So, you will see the growth pain once at start, once at 5,000 bytes, again at 10,000, again at 20,000. Appending strings will incur the pain every loop iteration.
try putting
ErrorDocument 404 /(root directory)/(error file)
in .htaccess
file.
Do this for any error but substitute 404 for your error.
I had to do a similar thing but I needed to add values with same keys. When I use merge or update I can't push values with same keys. So I had to use array of hashes.
my_hash_static = {:header =>{:company => 'xx', :usercode => 'xx', :password => 'xx',
:type=> 'n:n', :msgheader => from}, :body=>[]}
my_hash_dynamic = {:mp=>{:msg=>message, :no=>phones} }
my_hash_full = my_hash_static[:body].push my_hash_dynamic
You can use IntArrays.quickSort(array, comparator)
from fastutil library.
Just change your syntax ever so slightly:
CASE WHEN STATE = 2 AND RetailerProcessType = 1 THEN '"AUTHORISED"'
WHEN STATE = 1 AND RetailerProcessType = 2 THEN '"PENDING"'
WHEN STATE = 2 AND RetailerProcessType = 2 THEN '"AUTHORISED"'
ELSE '"DECLINED"'
END
If you don't put the field expression before the CASE
statement, you can put pretty much any fields and comparisons in there that you want. It's a more flexible method but has slightly more verbose syntax.
if you declare it as float or any decimal format it will display
0
only
E.g :
declare @weight float;
SET @weight= 47 / 638; PRINT @weight
Output : 0
If you want the output as
0.073667712
E.g
declare @weight float;
SET @weight= 47.000000000 / 638.000000000; PRINT @weight
Yes it is, there have to be boolean expresion after IF. Here you have a direct link. I hope it helps. GL!

Why not use 410? It suggests the requested resource no longer exists and the client is expected to never make a request for that resource, in your case users/9
.
You can find more details about 410 here: https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html
Modulus operator; gives the remainder of the left value divided by the right value. Like:
3 % 1
would equal zero (since 3 divides evenly by 1)
3 % 2
would equal 1 (since dividing 3 by 2 results in a remainder of 1).
If you only need read access and not write access and you are using the Microsoft.Extensions.Confiuration
(comes bundled in by default with ASP.NET Core but works with regular programs too) you can use the NuGet package Microsoft.Extensions.Configuration.Ini
to import ini files in to your configuration settings.
public Startup(IHostingEnvironment env)
{
var builder = new ConfigurationBuilder()
.SetBasePath(env.ContentRootPath)
.AddIniFile("SomeConfig.ini", optional: false);
Configuration = builder.Build();
}
You can also use ngrok: https://ngrok.com/. I use it all the time to have a public server running on my localhost. Hope this helps.
Another options which even provides your own custom domain for free are serveo.net and https://localtunnel.github.io/www/
Off the top of my head, you might try using the "margin: 0 auto" for #outer rather than #inner.
I often add background-color to my DIVs to see how they're laying out on the view. That might be a good way to diagnose what's going onn here.

Here is a simple 3 step ES6 implementation using function binding in the parent constructor. This is the first way the official react tutorial recommends (there is also public class fields syntax not covered here). You can find all of this information here https://reactjs.org/docs/handling-events.html
Binding Parent Functions so Children Can Call Them (And pass data up to the parent! :D )
Parent Function
handleFilterApply(filterVals){}
Parent Constructor
this.handleFilterApply = this.handleFilterApply.bind(this);
Prop Passed to Child
onApplyClick = {this.handleFilterApply}
Child Event Call
onClick = {() => {props.onApplyClick(filterVals)}
There are probably embedded tabs (CHAR(9)
) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:
DECLARE @var NVARCHAR(255), @i INT;
SET @i = 1;
SELECT @var = AccountType FROM dbo.Account
WHERE AccountNumber = 200
AND AccountType LIKE '%Daily%';
CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));
WHILE @i <= LEN(@var)
BEGIN
INSERT #x
SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));
SET @i = @i + 1;
END
SELECT i,c,a FROM #x ORDER BY i;
You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.
Ok to answer this . I simply converted my <
and the >
to <
and >
. What was happening previously is i used to set the text <script>alert('1')</script>
but before setting the text in the input text browserconverts <
and >
as <
and the >
. So hence converting them again to <
and >
since browser will understand that as only tags and converts them , than executing the script inside <input type="text" />
You can disable the event by applying following code:
with .attr()
API
$('#your_id').attr("disabled", "disabled");
or with .prop()
API
$('#your_id').prop('disabled', true);

This is old thread but answer because if useful to anyone.
Step 1. Your Db Storage Engine set to InnoDB
Step 2. Create Primary Table
here customer
is primary table and customer_id
is primary key
Step 3. create foreign key table and give index
here we have customer_addresses
as related table and store customer addresses, so here customer_id
relation with customer
table
we can select index directly when create table as below
If you forgot to give index when create a table, then you can give index from the structure tab of table as below.
Step 4. Once index give to the field, Go to structure tab and click on Relation View as shown in below pic
Step 5. Now select the ON DELETE and ON UPDATE what you want to do, Select column from current table, select DB (SAME DB), select relation table and primary key from that table as shown in below pic and Save it
Now check if relation are give successfully, go to foreign table data list and click on foreign key value, you will redirect to primary table record, then relation made successfully.

For strings like that, for me the most comfortable way to do it is doubling the ' or ", as explained in the MySQL manual:
There are several ways to include quote characters within a string:
A “'” inside a string quoted with “'” may be written as “''”. A “"” inside a string quoted with “"” may be written as “""”. Precede the quote character by an escape character (“\”). A “'” inside a string quoted with “"” needs no special treatment and need not be doubled or escaped. In the same way, “"” inside a
Strings quoted with “'” need no special treatment.
It is from http://dev.mysql.com/doc/refman/5.0/en/string-literals.html.
Before MySQL 5.7.6 this works from the command line:
mysql -e "SET PASSWORD FOR 'root'@'localhost' = PASSWORD('$w0rdf1sh');"
I don't have a mysql install to test on but I think in your case it would be
mysql -e "UPDATE mysql.user SET Password=PASSWORD('$w0rdf1sh') WHERE User='tate256';"
brew install vim --override-system-vi
Your classes should look like this
[XmlRoot("StepList")]
public class StepList
{
[XmlElement("Step")]
public List<Step> Steps { get; set; }
}
public class Step
{
[XmlElement("Name")]
public string Name { get; set; }
[XmlElement("Desc")]
public string Desc { get; set; }
}
Here is my testcode.
string testData = @"<StepList>
<Step>
<Name>Name1</Name>
<Desc>Desc1</Desc>
</Step>
<Step>
<Name>Name2</Name>
<Desc>Desc2</Desc>
</Step>
</StepList>";
XmlSerializer serializer = new XmlSerializer(typeof(StepList));
using (TextReader reader = new StringReader(testData))
{
StepList result = (StepList) serializer.Deserialize(reader);
}
If you want to read a text file you should load the file into a FileStream and deserialize this.
using (FileStream fileStream = new FileStream("<PathToYourFile>", FileMode.Open))
{
StepList result = (StepList) serializer.Deserialize(fileStream);
}
move
struct body bodies[n];
to after
struct body
{
double p[3];//position
double v[3];//velocity
double a[3];//acceleration
double radius;
double mass;
};
Rest all looks fine.
This is one way to do it using a list comprehension, though it's increasingly wasteful as the length of the rpt
string increases.

return ''.join([rpt for x in range(0, (len(rpt) % length))])[:length]

Some countries allow a single "0" character instead of "+" and others a double "0" character instead of the "+". Neither are standard.
The short answer is NO. It is not possible to rename a file in Git and remember the history. And it is a pain.
Rumor has it that git log --follow
--find-copies-harder
will work, but it does not work for me, even if there are zero changes to the file contents, and the moves have been made with git mv
.
(Initially I used Eclipse to rename and update packages in one operation, which may have confused Git. But that is a very common thing to do. --follow
does seem to work if only a mv
is performed and then a commit
and the mv
is not too far.)
Linus says that you are supposed to understand the entire contents of a software project holistically, not needing to track individual files. Well, sadly, my small brain cannot do that.
It is really annoying that so many people have mindlessly repeated the statement that Git automatically tracks moves. They have wasted my time. Git does no such thing. By design(!) Git does not track moves at all.
My solution is to rename the files back to their original locations. Change the software to fit the source control. With Git you just seem to need to "git" it right the first time.
Unfortunately, that breaks Eclipse, which seems to use --follow
. git log --follow
sometimes does not show the full history of files with complicated rename histories even though git log
does. (I do not know why.)
(There are some too clever hacks that go back and recommit old work, but they are rather frightening. See GitHub-Gist: emiller/git-mv-with-history.)

For anyone using Koa and koa-passport:
Know that the key for the user set in the serializeUser method (often a unique id for that user) will be stored in:
this.session.passport.user
When you set in done(null, user)
in deserializeUser where 'user' is some user object from your database:
this.req.user
OR
this.passport.user
for some reason this.user
Koa context never gets set when you call done(null, user) in your deserializeUser method.
So you can write your own middleware after the call to app.use(passport.session()) to put it in this.user like so:
app.use(function * setUserInContext (next) {
this.user = this.req.user
yield next
})
If you're unclear on how serializeUser and deserializeUser work, just hit me up on twitter. @yvanscher
.project
When a project is created in the workspace, a project description file is automatically generated that describes the project. The sole purpose of this file is to make the project self-describing, so that a project that is zipped up or released to a server can be correctly recreated in another workspace.
.classpath
Classpath specifies which Java source files and resource files in a project are considered by the Java builder and specifies how to find types outside of the project. The Java builder compiles the Java source files into the output folder and also copies the resources into it.
It depends on what you mean by stop. If it's in a function that can return void then:

You can use data URIs. Browser support varies; see Wikipedia. Example:
<a href="data:application/octet-stream;charset=utf-16le;base64,//5mAG8AbwAgAGIAYQByAAoA">text file</a>
The octet-stream is to force a download prompt. Otherwise, it will probably open in the browser.
For CSV, you can use:
<a href="data:application/octet-stream,field1%2Cfield2%0Afoo%2Cbar%0Agoo%2Cgai%0A">CSV Octet</a>

You may also want to look at rsync if you're doing a lot of files.
If you're going to making a lot of changes and want to keep your directories and files in sync, you may want to use a version control system like Subversion or Git. See http://xoa.petdance.com/How_to:_Keep_your_home_directory_in_Subversion
if you're using java.util.logging, then there is a configuration file that is doing this to log contents (unless you're using programmatic configuration). So, your options are
1) run post -processor that removes the line breaks
2) change the log configuration AND remove the line breaks from it. Restart your application (server) and you should be good.
Use chown
to change ownership and chmod
to change rights.
use the -R
option to apply the rights for all files inside of a directory too.
Note that both these commands just work for directories too. The -R
option makes them also change the permissions for all files and directories inside of the directory.
For example
sudo chown -R username:group directory
will change ownership (both user and group) of all files and directories inside of directory and directory itself.
sudo chown username:group directory
will only change the permission of the folder directory but will leave the files and folders inside the directory alone.
you need to use sudo to change the ownership from root to yourself.
Edit:
Note that if you use chown user: file
(Note the left-out group), it will use the default group for that user.
Also You can change the group ownership of a file or directory with the command:
chgrp group_name file/directory_name
You must be a member of the group to which you are changing ownership to.
You can find group of file as follows
# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file
# chown sujit:friends file
User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.
What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.
But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.
Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.
I think the parent Container needs to be given a maxWidth of the proper size. It looks like the Text box will fill whatever space it is given above.
As Matt J wrote, there is itoa
, but it's not standard. Your code will be more portable if you use snprintf
.
Absolutely - you basically want:
var results = from p in persons
group p.car by p.PersonId into g
select new { PersonId = g.Key, Cars = g.ToList() };
Or as a non-query expression:
var results = persons.GroupBy(
p => p.PersonId,
p => p.car,
(key, g) => new { PersonId = key, Cars = g.ToList() });
Basically the contents of the group (when viewed as an IEnumerable<T>
) is a sequence of whatever values were in the projection (p.car
in this case) present for the given key.
For more on how GroupBy
works, see my Edulinq post on the topic.
(I've renamed PersonID
to PersonId
in the above, to follow .NET naming conventions.)
Alternatively, you could use a Lookup
:
var carsByPersonId = persons.ToLookup(p => p.PersonId, p => p.car);
You can then get the cars for each person very easily:
// This will be an empty sequence for any personId not in the lookup
var carsForPerson = carsByPersonId[personId];
Take a look at http://json.org/. It claims a bit different list of escaped characters than Chris proposed.

That's not what map does. You really want Array.filter
. Or if you really want to remove the elements from the original list, you're going to need to do it imperatively with a for loop.
Try passing width=200
as additional paramater when creating the Label.
This should work in creating label with specified width.
If you want to change it later, you can use:
label.config(width=200)
As you want to change the size of font itself you can try:
label.config(font=("Courier", 44))
Those two parameters (or variants of) are sent, by convention, with all events.
sender
: The object which has raised the evente
an instance of EventArgs
including, in many cases, an object which inherits from EventArgs
. Contains additional information about the event, and sometimes provides ability for code handling the event to alter the event somehow.In the case of the events you mentioned, neither parameter is particularly useful. The is only ever one page raising the events, and the EventArgs
are Empty
as there is no further information about the event.
Looking at the 2 parameters separately, here are some examples where they are useful.
sender
Say you have multiple buttons on a form. These buttons could contain a Tag
describing what clicking them should do. You could handle all the Click
events with the same handler, and depending on the sender
do something different
private void HandleButtonClick(object sender, EventArgs e)
{
Button btn = (Button)sender;
if(btn.Tag == "Hello")
MessageBox.Show("Hello")
else if(btn.Tag == "Goodbye")
Application.Exit();
// etc.
}
Disclaimer : That's a contrived example; don't do that!
e
Some events are cancelable. They send CancelEventArgs
instead of EventArgs
. This object adds a simple boolean property Cancel
on the event args. Code handling this event can cancel the event:
private void HandleCancellableEvent(object sender, CancelEventArgs e)
{
if(/* some condition*/)
{
// Cancel this event
e.Cancel = true;
}
}
You can use a global variable within other functions by declaring it as global
within each function that assigns a value to it:
globvar = 0
def set_globvar_to_one():
global globvar # Needed to modify global copy of globvar
globvar = 1
def print_globvar():
print(globvar) # No need for global declaration to read value of globvar
set_globvar_to_one()
print_globvar() # Prints 1
I imagine the reason for it is that, since global variables are so dangerous, Python wants to make sure that you really know that's what you're playing with by explicitly requiring the global
keyword.
See other answers if you want to share a global variable across modules.

I used double quotes for the URL and it worked. So something like
git clone "??http://git.fedorahosted.org/git/ibus-typing-booster.git"
works.. single quotes dont help. It has to be double quotes.
In addition to the above answer, this is the actual code:
[[UIDevice currentDevice] name];
You can easy get that effect without using jQueryUI, for example:
$(document).ready(function(){
$('#slide').click(function(){
var hidden = $('.hidden');
if (hidden.hasClass('visible')){
hidden.animate({"left":"-1000px"}, "slow").removeClass('visible');
} else {
hidden.animate({"left":"0px"}, "slow").addClass('visible');
}
});
});
Try this working Fiddle:
problem is not in the code, but you don't have added the driver to your project!!!
You have to add the *.jar
driver to your project...
Try putting this in your lib directory, then re-starting tomcat...
problem is Class.forName("com.mysql.jdbc.Driver");
it tries to load the driver, but it is not getting it, this is the reason you are getting:
java.lang.ClassNotFoundException.
Using AES or implementing AES? To use AES, there is the System.Security.Cryptography.RijndaelManaged class.
If you want to compare files visually you can use:
git difftool
It will start your diff app automatically for each changed file.
PS: If you did not set a diff app, you can do it like in the example below(I use Winmerge):
git config --global merge.tool winmerge
git config --replace --global mergetool.winmerge.cmd "\"C:\Program Files (x86)\WinMerge\WinMergeU.exe\" -e -u -dl \"Base\" -dr \"Mine\" \"$LOCAL\" \"$REMOTE\" \"$MERGED\""
git config --global mergetool.prompt false

I face similar issue while importing TensorFlow
. If you are using Tensorflow which uses Pandas library, I suggest restarting your kernel of Anaconda
. This works for me.
const one={name:'mohit' , age:30};
//const two ={name:'mohit',age:30};
const two ={age:30,name:'mohit'};
function isEquivalent(a, b) {
// Create arrays of property names
var aProps = Object.getOwnPropertyNames(a);
var bProps = Object.getOwnPropertyNames(b);
// If number of properties is different,
// objects are not equivalent
if (aProps.length != bProps.length) {
return false;
}
for (var i = 0; i < aProps.length; i++) {
var propName = aProps[i];
// If values of same property are not equal,
// objects are not equivalent
if (a[propName] !== b[propName]) {
return false;
}
}
// If we made it this far, objects
// are considered equivalent
return true;
}
console.log(isEquivalent(one,two))
The array form of new-expression accepts only one form of initializer: an empty ()
. This, BTW, has the same effect as the empty {}
in your non-dynamic initialization.
The above applies to pre-C++11 language. Starting from C++11 one can use uniform initialization syntax with array new-expressions
char* c = new char[length]{};
char* d = new char[length]{ 'a', 'b', 'c' };
You don't put a component in directives
You register it in @NgModule
declarations:
@NgModule({
imports: [ BrowserModule ],
declarations: [ App , MyChildComponent ],
bootstrap: [ App ]
})
and then You just put it in the Parent's Template HTML as : <my-child></my-child>
That's it.
You can simply just pass the attribute you want without any annotations in your controller:
@RequestMapping(value = "/someUrl")
public String someMethod(String valueOne) {
//do stuff with valueOne variable here
}
Works with GET and POST

In this day and age of mouse driven computers and tablets with touch screens etc, it is often forgotten to cater for input via keyboard only. A button should support a focus rectangle (the dotted rectangle when the button has focus) or another shape matching the button shape.
To add a focus rectangle to the button, use this XAML (from this site). Focus rectangle style:
<Style x:Key="ButtonFocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Border>
<Rectangle Margin="2" StrokeThickness="1" Stroke="#60000000" StrokeDashArray="1 2" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Applying the style to the button:
<Style TargetType="Button">
<Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}" />

To get the size of the directory hdfs dfs -du -s -h /$yourDirectoryName can be used. hdfs dfsadmin -report can be used to see a quick cluster level storage report.
Apart from above information, there is still an interesting history of LF (\n) and CR (\r). [Original author : ??? Source : http://www.ruanyifeng.com/blog/2006/04/post_213.html] Before computer came out, there was a type of teleprinter called Teletype Model 33. It can print 10 characters each second. But there is one problem with this, after finishing printing each line, it will take 0.2 second to move to next line, which is time of printing 2 characters. If a new characters is transferred during this 0.2 second, then this new character will be lost.
So scientists found a way to solve this problem, they add two ending characters after each line, one is 'Carriage return', which is to tell the printer to bring the print head to the left.; the other one is 'Line feed', it tells the printer to move the paper up 1 line.
Later, computer became popular, these two concepts are used on computers. At that time, the storage device was very expensive, so some scientists said that it was expensive to add two characters at the end of each line, one is enough, so there are some arguments about which one to use.
In UNIX/Mac and Linux, '\n' is put at the end of each line, in Windows, '\r\n' is put at the end of each line. The consequence of this use is that files in UNIX/Mac will be displayed in one line if opened in Windows. While file in Windows will have one ^M at the end of each line if opened in UNIX or Mac.
You can do this:
HTML code:
<form action="submit.php" method="get" id="form">
<a href="javascript: submitForm()">
<img src="save.gif" alt="Save icon"/>
<br/>
save
</a>
</form>
note: you can use and action and method of your choice and Id and any text starting from href="javascript: and ending to ()" but make sure that when I type the same things such as id and some text you type in your replacement in the same places(java script and HTML code).
java script code:
var form=document.getElementById("form");
function submitForm()
{
form.submit();
}
All these seem way too complicated and I guess it gets into a debate about what exactly adding "a month" means. Does it mean 30 days? Does it mean from the 1st to the 1st? From the last day to the last day?
If the latter, then adding a month to Feb 27th gets you to March 27th, but adding a month to Feb 28th gets you to March 31st (except in leap years, where it gets you to March 28th). Then subtracting a month from March 30th gets you... Feb 27th? Who knows...
For those looking for a simple solution, just add milliseconds and be done.
function getDatePlusDays(dt, days) {
return new Date(dt.getTime() + (days * 86400000));
}
or
Date.prototype.addDays = function(days) {
this = new Date(this.getTime() + (days * 86400000));
};
jQuery code snippet to get the dynamic variables stored in the url as parameters and store them as JavaScript variables ready for use with your scripts:
$.urlParam = function(name){
var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.href);
if (results==null){
return null;
}
else{
return results[1] || 0;
}
}
example.com?param1=name¶m2=&id=6
$.urlParam('param1'); // name
$.urlParam('id'); // 6
$.urlParam('param2'); // null
//example params with spaces
http://www.jquery4u.com?city=Gold Coast
console.log($.urlParam('city'));
//output: Gold%20Coast
console.log(decodeURIComponent($.urlParam('city')));
//output: Gold Coast
If your data field is already a DateTime datatype, you don't need to use [DataType(DataType.Date)]
for the annotation; just use:
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
on the jQuery, use datepicker for you calendar
$(document).ready(function () {
$('#StartDate').datepicker();
});
on your HTML, use EditorFor
helper:
@Html.EditorFor(model => model.StartDate)
I think what you're looking for is an IP Geolocation database or service provider. There are many out there and some are free (get what you pay for).
Although I haven't used this service before, it claims to be in real-time. https://kickfire.com/kf-api
Here's another IP geo location API from Abstract API - https://www.abstractapi.com/ip-geolocation-api
But just do a google search on IP geo and you'll get more results than you need.
Replace every col-md-

This is the thing that worked for me to get me rid of this problem you can see what you have to replace.
And if you didn't want to use strict equality, you could use exists:
myFunction(strings.exists { x => customPredicate(x) })
If you would like to combine the matrix with some visualisations I can recommend (I am using the built in iris
dataset):
library(psych)
pairs.panels(iris[1:4]) # select columns 1-4
The Performance Analytics basically does the same but includes significance indicators by default.
library(PerformanceAnalytics)
chart.Correlation(iris[1:4])
Or this nice and simple visualisation:
library(corrplot)
x <- cor(iris[1:4])
corrplot(x, type="upper", order="hclust")
if you are getting this exception again and again then download my-sql connector and paste in tomcat/WEB-INF/lib folder...note that some times WEB-INF folder does not contains lib folder, at that time manually create lib folder and paste mysql connector in that folder..definitely this will work.if still you got problem then check that your jdk must match your system. i.e if your system is 64 bit then jdk must be 64 bit
This might sound really simplistic...
But this will center the div inside the div, exactly in the center in relation to left and right margin or parent container, but you can adjust percentage symmetrically on left and right.
margin-right: 10%;
margin-left: 10%;
Then you can adjust % to make it as wide as you want it.
Well, first you need to request the username of the user from the session in your controller action like this:
$username=$this->get('security.context')->getToken()->getUser()->getUserName();
then do a query to the db and get your object with regular dql like
$em = $this->get('doctrine.orm.entity_manager');
"SELECT u FROM Acme\AuctionBundle\Entity\User u where u.username=".$username;
$q=$em->createQuery($query);
$user=$q->getResult();
the $user should now hold the user with this username ( you could also use other fields of course)
...but you will have to first configure your /app/config/security.yml configuration to use the appropriate field for your security provider like so:
security:
provider:
example:
entity: {class Acme\AuctionBundle\Entity\User, property: username}
hope this helps!
The answer of delfuego is the simplest way to solve the certificate problem. But, in my case, one of our third party url (using https), updated their certificate every 2 months automatically. It means that I have to import the cert to our Java trust store manually every 2 months as well. Sometimes it caused production problems.
So, I made a method to solve it with SecureRestClientTrustManager to be able to consume https url without importing the cert file. Here is the method:
public static String doPostSecureWithHeader(String url, String body, Map headers) throws Exception { log.info("start doPostSecureWithHeader " + url + " with param " + body); long startTime; long endTime; startTime = System.currentTimeMillis(); Client client; client = Client.create(); WebResource webResource; webResource = null; String output = null; try{ SSLContext sslContext = null; SecureRestClientTrustManager secureRestClientTrustManager = new SecureRestClientTrustManager(); sslContext = SSLContext.getInstance("SSL"); sslContext .init(null, new javax.net.ssl.TrustManager[] { secureRestClientTrustManager }, null); DefaultClientConfig defaultClientConfig = new DefaultClientConfig(); defaultClientConfig .getProperties() .put(com.sun.jersey.client.urlconnection.HTTPSProperties.PROPERTY_HTTPS_PROPERTIES, new com.sun.jersey.client.urlconnection.HTTPSProperties( getHostnameVerifier(), sslContext)); client = Client.create(defaultClientConfig); webResource = client.resource(url); if(headers!=null && headers.size()>0){ for (Map.Entry entry : headers.entrySet()){ webResource.setProperty(entry.getKey(), entry.getValue()); } } WebResource.Builder builder = webResource.accept("application/json"); if(headers!=null && headers.size()>0){ for (Map.Entry entry : headers.entrySet()){ builder.header(entry.getKey(), entry.getValue()); } } ClientResponse response = builder .post(ClientResponse.class, body); output = response.getEntity(String.class); } catch(Exception e){ log.error(e.getMessage(),e); if(e.toString().contains("One or more of query value parameters are null")){ output="-1"; } if(e.toString().contains("401 Unauthorized")){ throw e; } } finally { if (client!= null) { client.destroy(); } } endTime = System.currentTimeMillis(); log.info("time hit "+ url +" selama "+ (endTime - startTime) + " milliseconds dengan output = "+output); return output; }
As a note of caution this answer provided by the user above me is correct.

// date picker dialog
datePickerDialog = new DatePickerDialog(frmFlightDetails.this,
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
// set day of month , month and year value in the edit text
dpFlightDate.setText(dayOfMonth + "/"
+ (monthOfYear + 1) + "/" + year);
}
}, mYear, mMonth, mDay);
datePickerDialog.show();
}
});
tpFlightTime.setOnClickListener(new View.OnClickListener() {

You could use a string stream and read the elements into the vector.
Here are many different examples...
A copy of one of the examples:
std::vector<std::string> split(const std::string& s, char seperator)
{
std::vector<std::string> output;
std::string::size_type prev_pos = 0, pos = 0;
while((pos = s.find(seperator, pos)) != std::string::npos)
{
std::string substring( s.substr(prev_pos, pos-prev_pos) );
output.push_back(substring);
prev_pos = ++pos;
}
output.push_back(s.substr(prev_pos, pos-prev_pos)); // Last word
return output;
}
Loop and count in all browsers:
var cnt = 0;
for (var i = 0; i < arr.length; i++) {
if (arr[i] !== undefined) {
++cnt;
}
}
In modern browsers:
var cnt = 0;
arr.foreach(function(val) {
if (val !== undefined) { ++cnt; }
})
Using the below line
SELECT LEFT(subject , 10) FROM tbl
In my case, this error started appearing randomly and wouldn't go away even after setting a timeout of 30000. Simply ending the process in the terminal and re-running the tests resolved the issue for me. I have also removed the timeout and tests are still passing again.
Other answers seem to point to the code source which is Jar file location which is not a directory.

You need mask
:
sample['PR'] = sample['PR'].mask(sample['PR'] < 90, np.nan)
Another solution with loc
and boolean indexing
:
sample.loc[sample['PR'] < 90, 'PR'] = np.nan
Sample:
import pandas as pd
import numpy as np
sample = pd.DataFrame({'PR':[10,100,40] })
print (sample)
PR
0 10
1 100
2 40
sample['PR'] = sample['PR'].mask(sample['PR'] < 90, np.nan)
print (sample)
PR
0 NaN
1 100.0
2 NaN
sample.loc[sample['PR'] < 90, 'PR'] = np.nan
print (sample)
PR
0 NaN
1 100.0
2 NaN
EDIT:
Solution with apply
:
sample['PR'] = sample['PR'].apply(lambda x: np.nan if x < 90 else x)

I think I got it at last by doing some manual transformations with the data before visualization:
d <- diamonds
# computing logarithm of prices
d$price <- log10(d$price)
And work out a formatter to later compute 'back' the logarithmic data:
formatBack <- function(x) 10^x
# or with special formatter (here: "dollar")
formatBack <- function(x) paste(round(10^x, 2), "$", sep=' ')
And draw the plot with given formatter:
m <- ggplot(d, aes(y = price, x = color))
m + geom_boxplot() + scale_y_continuous(formatter='formatBack')
Sorry to the community to bother you with a question I could have solved before! The funny part is: I was working hard to make this plot work a month ago but did not succeed. After asking here, I got it.
Anyway, thanks to @DWin for motivation!
Some limitations though to Steven Bethard's solution :
When you register your class method as a function, the destructor of your class is surprisingly called every time your method processing is finished. So if you have 1 instance of your class that calls n times its method, members may disappear between 2 runs and you may get a message malloc: *** error for object 0x...: pointer being freed was not allocated
(e.g. open member file) or pure virtual method called,
terminate called without an active exception
(which means than the lifetime of a member object I used was shorter than what I thought). I got this when dealing with n greater than the pool size. Here is a short example :
from multiprocessing import Pool, cpu_count
from multiprocessing.pool import ApplyResult
# --------- see Stenven's solution above -------------
from copy_reg import pickle
from types import MethodType
def _pickle_method(method):
func_name = method.im_func.__name__
obj = method.im_self
cls = method.im_class
return _unpickle_method, (func_name, obj, cls)
def _unpickle_method(func_name, obj, cls):
for cls in cls.mro():
try:
func = cls.__dict__[func_name]
except KeyError:
pass
else:
break
return func.__get__(obj, cls)
class Myclass(object):
def __init__(self, nobj, workers=cpu_count()):
print "Constructor ..."
# multi-processing
pool = Pool(processes=workers)
async_results = [ pool.apply_async(self.process_obj, (i,)) for i in range(nobj) ]
pool.close()
# waiting for all results
map(ApplyResult.wait, async_results)
lst_results=[r.get() for r in async_results]
print lst_results
def __del__(self):
print "... Destructor"
def process_obj(self, index):
print "object %d" % index
return "results"
pickle(MethodType, _pickle_method, _unpickle_method)
Myclass(nobj=8, workers=3)
# problem !!! the destructor is called nobj times (instead of once)
Output:
Constructor ...
object 0
object 1
object 2
... Destructor
object 3
... Destructor
object 4
... Destructor
object 5
... Destructor
object 6
... Destructor
object 7
... Destructor
... Destructor
... Destructor
['results', 'results', 'results', 'results', 'results', 'results', 'results', 'results']
... Destructor
The __call__
method is not so equivalent, because [None,...] are read from the results :
from multiprocessing import Pool, cpu_count
from multiprocessing.pool import ApplyResult
class Myclass(object):
def __init__(self, nobj, workers=cpu_count()):
print "Constructor ..."
# multiprocessing
pool = Pool(processes=workers)
async_results = [ pool.apply_async(self, (i,)) for i in range(nobj) ]
pool.close()
# waiting for all results
map(ApplyResult.wait, async_results)
lst_results=[r.get() for r in async_results]
print lst_results
def __call__(self, i):
self.process_obj(i)
def __del__(self):
print "... Destructor"
def process_obj(self, i):
print "obj %d" % i
return "result"
Myclass(nobj=8, workers=3)
# problem !!! the destructor is called nobj times (instead of once),
# **and** results are empty !
So none of both methods is satisfying...
Use AFNetworking; Put other parameters in the parameter dictionary and append the image data in form data.

-(BOOL)uploadImageAFNetworkingWithURL:(NSString *)path andImage:(UIImage *)image andImageNameWithExtension:(NSString *)strImageName andParamDict:(NSDictionary *)dictParam andKeyForUploadingImage:(NSString *)keyUplaodImg{
NSData *imageData = UIImageJPEGRepresentation(image, 0.5);
NSString *strError = EMPTY_STRING;
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager POST:path parameters:dictParam constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:keyUplaodImg fileName:strImageName mimeType:@"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"success = %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"error = %@", error);
NSLog(@"Response = %@", operation);
[strError stringByAppendingString:STR_ERR_MESSAGE];
}];
if(strError.length>0){
return NO;
}else{
return YES;
}
}
here, Use explode() function to convert string into array, by a string
click here to know more about explode()
$str = "this is string";
$delimiter = ' '; // use any string / character by which, need to split string into Array
$resultArr = explode($delimiter, $str);
var_dump($resultArr);
Output :
Array
(
[0] => "this",
[1] => "is",
[2] => "string "
)
it is same as the requirements:
arr[0]="this";
arr[1]="is";
arr[2]="string";
You want to pass these extra parameters to subprocess.Popen
:
bufsize=1, universal_newlines=True
Then you can iterate as in your example. (Tested with Python 3.5)
The ECMAscript standard does not specify which sort algorithm is to be used. Indeed, different browsers feature different sort algorithms. For example, Mozilla/Firefox's sort() is not stable (in the sorting sense of the word) when sorting a map. IE's sort() is stable.
This may be of some help (do not literally write out the backslashes '\' in the commands, they are meant to indicate that "everything has to be on one line"):
It seems that all the commands (in grey) take any type of key file (in green) as "in" argument. Which is nice.
Here are the commands again for easier copy-pasting:
openssl rsa -in $FF -out $TF
openssl rsa -aes256 -in $FF -out $TF
openssl pkcs8 -topk8 -nocrypt -in $FF -out $TF
openssl pkcs8 -topk8 -v2 aes-256-cbc -v2prf hmacWithSHA256 -in $FF -out $TF
and
openssl rsa -check -in $FF
openssl rsa -text -in $FF
The error comes up when you are trying to assign a list of numpy array of different length to a data frame, and it can be reproduced as follows:
A data frame of four rows:
df = pd.DataFrame({'A': [1,2,3,4]})
Now trying to assign a list/array of two elements to it:
df['B'] = [3,4] # or df['B'] = np.array([3,4])
Both errors out:
ValueError: Length of values does not match length of index
Because the data frame has four rows but the list and array has only two elements.
Work around Solution (use with caution): convert the list/array to a pandas Series, and then when you do assignment, missing index in the Series will be filled with NaN:
df['B'] = pd.Series([3,4])
df
# A B
#0 1 3.0
#1 2 4.0
#2 3 NaN # NaN because the value at index 2 and 3 doesn't exist in the Series
#3 4 NaN
For your specific problem, if you don't care about the index or the correspondence of values between columns, you can reset index for each column after dropping the duplicates:
df.apply(lambda col: col.drop_duplicates().reset_index(drop=True))
# A B
#0 1 1.0
#1 2 5.0
#2 7 9.0
#3 8 NaN
From C# 6:
var dateTimeUtcAsString = $"{DateTime.UtcNow:o}";
The result will be: "2019-01-15T11:46:33.2752667Z"
This answer covers what's what in terms of variables and importantly, output size shall be same for input frame and video size.
import cv2
save_name = "output.mp4"
fps = 10
width = 600
height = 480
output_size = (width, height)
out = cv2.VideoWriter(save_name,cv2.VideoWriter_fourcc('M','J','P','G'), fps , output_size )
cap = cv2.VideoCapture(0) # 0 for webcam or you can put in videopath
while(True):
_, frame = cap.read()
cv2.imshow('Video Frame', frame)
out.write(cv2.resize(frame, output_size ))
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
out.release()
cv2.destroyAllWindows()
UPDATE Table1 SET col1= col2 FROM (SELECT col2, col3 FROM Table2) as newTbl WHERE col4= col3
Here col4 & col1 are in Table1. col2 & col3 are in Table2
I Am trying to update each col1 where col4 = col3 different value for each row
Another php solution, but with PDO:
<?php
try {
$pdo = new PDO('mysql:host=localhost;dbname=dbname', 'root', 'password');
echo 'table dbname exists...';
}
catch (PDOException $e) {
die('dbname not found...');
}
This works for me

The DataSet object has a Tables array. If you know the table you want, it will have a Row array, each object of which has an ItemArray array. In your case the code would most likely be
int var1 = int.Parse(ds.Tables[0].Rows[0].ItemArray[4].ToString());
and so forth. This would give you the 4th item in the first row. You can also use Columns instead of ItemArray and specify the column name as a string instead of remembering it's index. That approach can be easier to keep up with if the table structure changes. So that would be
int var1 = int.Parse(ds.Tables[0].Rows[0]["MyColumnName"].ToString());
First of all, let's try to make your code a little simpler:
// No need to create a circle unless it is clearly necessary to
// demonstrate the problem
// Your Rect2f defines a default constructor, so let's use it for simplicity.
shared_ptr<Shape> rect(new Rect2f());
Okay, so now we see that the parentheses are clearly balanced. What else could it be? Let's check the following code snippet's error:
int main() {
delete new T();
}
This may seem like weird usage, and it is, but I really hate memory leaks. However, the output does seem useful:
In function 'int main()':
Line 2: error: expected type-specifier before 'T'
Aha! Now we're just left with the error about the parentheses. I can't find what causes that; however, I think you are forgetting to include the file that defines Rect2f
.
Modules go in site-packages
and executables go in your system's executable path. For your environment, this path is /usr/local/bin/
.
To avoid having to deal with this, simply use easy_install
, distribute
or pip
. These tools know which files need to go where.
You use the Python 2 docs but write your program in Python 3.
Try this:
sys.getsizeof(object)
getsizeof() Return the size of an object in bytes. It calls the object’s __sizeof__
method and adds an additional garbage collector overhead if the object is managed by the garbage collector.
As someone that has ran into this problem constantly with java repositories on Windows, the best solution is to install Cygwin (https://www.cygwin.com/) and use its git installation under all > devel > git.
The reason this is the best solution I have come across is since Cygwin manages the long path names so other provided commands benefit. Ex: find, cp and rm. Trust me, the real problem begins when you have to delete path names that are too long in Windows.
I know I'm a bit late, but was able to fix this issue by following the docs directly.
Add the meta-data tag to AndroidManifest.xml
(so the system knows)
<activity
android:name=".Sub"
android:label="Sub-Activity"
android:parentActivityName=".MainChooser"
android:theme="@style/AppTheme.NoActionBar">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".MainChooser" />
</activity>
Next, enable the back (up) button in your MainActivity
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_child);
// my_child_toolbar is defined in the layout file
Toolbar myChildToolbar =
(Toolbar) findViewById(R.id.my_child_toolbar);
setSupportActionBar(myChildToolbar);
// Get a support ActionBar corresponding to this toolbar
ActionBar ab = getSupportActionBar();
// Enable the Up button
ab.setDisplayHomeAsUpEnabled(true);
}
And, you will be all set up!

Using reduce()
from purrr
is slightly faster than rowSums
and definately faster than apply
, since you avoid iterating over all the rows and just take advantage of the vectorized operations:
library(purrr)
library(dplyr)
iris %>% mutate(Petal = reduce(select(., starts_with("Petal")), `+`))
See this for timings
div.style
yields an object (CSSStyleDeclaration). Since it's an object, you can alternatively use the following:
div.style["top"] = "200px";
div.style["left"] = "200px";
This is useful, for example, if you need to access a "variable" property:
div.style[prop] = "200px";
should call the function properly; like- Fibonacci:input
max_connections
You can change max_connections
while MySQL is running via SET
:
mysql> SET GLOBAL max_connections = 5000;
Query OK, 0 rows affected (0.00 sec)
mysql> SHOW VARIABLES LIKE "max_connections";
+-----------------+-------+
| Variable_name | Value |
+-----------------+-------+
| max_connections | 5000 |
+-----------------+-------+
1 row in set (0.00 sec)
timeout
relatedI had never seen your error message before, so I googled. probably, you are using Connector/Net. Connector/Net Manual says there is max connection pool size. (default is 100) see table 22.21.
I suggest that you increase this value to 100k or disable connection pooling Pooling=false
he has two questions.
Q1 - what happens if I disable pooling
Slow down making DB connection. connection pooling
is a mechanism that use already made DB connection. cost of Making new connection is high. http://en.wikipedia.org/wiki/Connection_pool
Q2 - Can the value of pooling be increased or the maximum is 100?
you can increase but I'm sure what is MAX value, maybe max_connections
in my.cnf
My suggestion is that do not turn off Pooling, increase value by 100 until there is no connection error.

Your "bad" output is UTF-8 displayed as CP1252.
On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:
df.to_csv('file.csv',encoding='utf-8-sig')
That encoder will add the BOM.
You can continue using WebClient to POST (instead of GET, which is the HTTP verb you're currently using with DownloadString), but I think you'll find it easier to work with the (slightly) lower-level classes WebRequest and WebResponse.
There are two parts to this - the first is to post the login form, the second is recovering the "Set-cookie" header and sending that back to the server as "Cookie" along with your GET request. The server will use this cookie to identify you from now on (assuming it's using cookie-based authentication which I'm fairly confident it is as that page returns a Set-cookie header which includes "PHPSESSID").
POSTing to the login form
Form posts are easy to simulate, it's just a case of formatting your post data as follows:
field1=value1&field2=value2
Using WebRequest and code I adapted from Scott Hanselman, here's how you'd POST form data to your login form:
string formUrl = "http://www.mmoinn.com/index.do?PageModule=UsersAction&Action=UsersLogin"; // NOTE: This is the URL the form POSTs to, not the URL of the form (you can find this in the "action" attribute of the HTML's form tag
string formParams = string.Format("email_address={0}&password={1}", "your email", "your password");
string cookieHeader;
WebRequest req = WebRequest.Create(formUrl);
req.ContentType = "application/x-www-form-urlencoded";
req.Method = "POST";
byte[] bytes = Encoding.ASCII.GetBytes(formParams);
req.ContentLength = bytes.Length;
using (Stream os = req.GetRequestStream())
{
os.Write(bytes, 0, bytes.Length);
}
WebResponse resp = req.GetResponse();
cookieHeader = resp.Headers["Set-cookie"];
Here's an example of what you should see in the Set-cookie header for your login form:
PHPSESSID=c4812cffcf2c45e0357a5a93c137642e; path=/; domain=.mmoinn.com,wowmine_referer=directenter; path=/; domain=.mmoinn.com,lang=en; path=/;domain=.mmoinn.com,adt_usertype=other,adt_host=-
GETting the page behind the login form
Now you can perform your GET request to a page that you need to be logged in for.
string pageSource;
string getUrl = "the url of the page behind the login";
WebRequest getRequest = WebRequest.Create(getUrl);
getRequest.Headers.Add("Cookie", cookieHeader);
WebResponse getResponse = getRequest.GetResponse();
using (StreamReader sr = new StreamReader(getResponse.GetResponseStream()))
{
pageSource = sr.ReadToEnd();
}
EDIT:
If you need to view the results of the first POST, you can recover the HTML it returned with:
using (StreamReader sr = new StreamReader(resp.GetResponseStream()))
{
pageSource = sr.ReadToEnd();
}
Place this directly below cookieHeader = resp.Headers["Set-cookie"];
and then inspect the string held in pageSource.
You can combine data from the two tables, order by goals highest first and then choose the top two like this:
MySQL
select *
from (
select * from tblMadrid
union all
select * from tblBarcelona
) alldata
order by goals desc
limit 0,2;
SQL Server
select top 2 *
from (
select * from tblMadrid
union all
select * from tblBarcelona
) alldata
order by goals desc;
If you only want Messi and Ronaldo
select * from tblBarcelona where name = 'messi'
union all
select * from tblMadrid where name = 'ronaldo'
To ensure that messi is at the top of the result, you can do something like this:
select * from (
select * from tblBarcelona where name = 'messi'
union all
select * from tblMadrid where name = 'ronaldo'
) stars
order by name;
For anyone coming across this thread, here's a script called thatsNotYoChild.js that I just wrote that solves this problem automatically:
http://www.impressivewebs.com/fixing-parent-child-opacity/
Basically, it separates children from the parent element, but keeps the element in the same physical location on the page.
You can use static final to create something that works similar to Const, I have used this in the past.
protected static final int cOTHER = 0;
protected static final int cRPM = 1;
protected static final int cSPEED = 2;
protected static final int cTPS = 3;
protected int DataItemEnum = 0;
public static final int INVALID_PIN = -1;
public static final int LED_PIN = 0;

.
// A programmer walked through the parking lot in search of his car
// When he neared it, he reached for his pocket to grab his array of keys
$keyChain = array(
'office-door' => unlockOffice(),
'home-key' => unlockSmallApartment(),
'wifes-mercedes' => unusedKeyAfterDivorce(),
'safety-deposit-box' => uselessKeyForEmptyBox(),
'rusto-old-car' => unlockOldBarrel(),
);
// He tried and tried but couldn't find the right key for his car
// And so he wondered if he had the right key with him.
// To determine this he used array_key_exists
if (array_key_exists('rusty-old-car', $keyChain)) {
print('Its on the chain.');
}
Note for anyone running Vagrant: this can be caused by a bug with their shared folders. Specify NFS for your shared folders in your Vagrantfile to avoid this happening.
Simply adding type: "nfs"
to the end will do the trick, like so:
config.vm.synced_folder ".", "/vagrant", type: "nfs"
Add height & width properties to your .css file.
Wrong syntax. Here you are:
insert into user_by_category (game_category,customer_id) VALUES ('Goku','12');
or:
insert into user_by_category ("game_category","customer_id") VALUES ('Kakarot','12');
The second one is normally used for case-sensitive column names.
I have used this simple code, and it works!
for (int i = 0; i < N * N; i++)
{
Thread.Sleep(50);
progressBar1.BeginInvoke(new Action(() => progressBar1.Value = i));
progressBar1.CreateGraphics().DrawString(i.ToString() + "%", new Font("Arial",
(float)10.25, FontStyle.Bold),
Brushes.Red, new PointF(progressBar1.Width / 2 - 10, progressBar1.Height / 2 - 7));
}
It just has one simple problem and this is it: when progress bar start to rising, percentage some times hide, and then appear again. I did't write it myself.I found it here: text on progressbar in c#
I used this code, and it does work.
You can use two elements, one inside the other, and give the outer one overflow: hidden
and a width equal to the inner element together with a bottom padding so that the shadow on all the other sides are "cut off"
#outer {
width: 100px;
overflow: hidden;
padding-bottom: 10px;
}
#outer > div {
width: 100px;
height: 100px;
background: orange;
-moz-box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
-webkit-box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
}
Alternatively, float the outer element to cause it to shrink to the size of the inner element. See: http://jsfiddle.net/QJPd5/1/
The following is a group of versatile C functions for timer management based on the gettimeofday() system call. All the timer properties are contained in a single ticktimer struct - the interval you want, the total running time since the timer initialization, a pointer to the desired callback you want to call, the number of times the callback was called. A callback function would look like this:
void your_timer_cb (struct ticktimer *t) {
/* do your stuff here */
}
To initialize and start a timer, call ticktimer_init(your_timer, interval, TICKTIMER_RUN, your_timer_cb, 0).
In the main loop of your program call ticktimer_tick(your_timer) and it will decide whether the appropriate amount of time has passed to invoke the callback.
To stop a timer, just call ticktimer_ctl(your_timer, TICKTIMER_STOP).

If you need this solution for only few types of modals just use
style="width:90%"
attribute.
example:
div class="modal-dialog modal-lg" style="width:90%"
note: this will change only this particular modal
You can use:
if ((DateTime.Compare(dateToCompare, dateIn) == 1) && (DateTime.Compare(dateToCompare, dateOut) == 1)
{
//do code here
}
or
if ((dateToCompare.CompareTo(dateIn) == 1) && (dateToCompare.CompareTo(dateOut) == 1))
{
//do code here
}
