This code for use of delete keyword or free function. But when create a pointer object using 'malloc' or 'new' and deallocate object memory using delete even that object pointer can be call function in the class. After that use free instead of delete then also it works after free statement , but when use both then only pointer object can't call to function in class.. the code is as follows :
#include<iostream>
using namespace std;
class ABC{
public: ABC(){
cout<<"Hello"<<endl;
}
void disp(){
cout<<"Hi\n";
}
};
int main(){
ABC* b=(ABC*)malloc(sizeof(ABC));
int* q = new int[20];
ABC *a=new ABC();
b->disp();
cout<<b<<endl;
free(b);
delete b;
//a=NULL;
b->disp();
ABC();
cout<<b;
return 0;
}
output :
Hello Hi 0x2abfef37cc20
I have used "Pattern 2 - the "factory helper pattern"
Pattern 2 - the factory helper pattern
One case where this pattern won't work is if MyClass is final. Most of the Mockito framework doesn't play particularly well with final classes; and this includes the use of spy(). Another case is where MyClass uses getClass() somewhere, and requires the resulting value to be MyClass. This won't work, because the class of a spy is actually a Mockito-generated subclass of the original class.
In either of these cases, you'll need the slightly more robust factory helper pattern, as follows.
public class MyClass{ static class FactoryHelper{ Foo makeFoo( A a, B b, C c ){ return new Foo( a, b, c ); } } //... private FactoryHelper helper; public MyClass( X x, Y y ){ this( x, y, new FactoryHelper()); } MyClass( X x, Y, y, FactoryHelper helper ){ //... this.helper = helper; } //... Foo foo = helper.makeFoo( a, b, c ); }
So, you have a special constructor, just for testing, that has an additional argument. This is used from your test class, when creating the object that you're going to test. In your test class, you mock the FactoryHelper class, as well as the object that you want to create.
@Mock private MyClass.FactoryHelper mockFactoryHelper; @Mock private Foo mockFoo; private MyClass toTest;
and you can use it like this
toTest = new MyClass( x, y, mockFactoryHelper ); when( mockFactoryHelper.makeFoo( any( A.class ), any( B.class ), any( C.class ))) .thenReturn( mockFoo );
If you don't like nested list comprehensions, you can make use of the map function as well,
>>> from pprint import pprint
>>> l = l = [['40', '20', '10', '30'], ['20', '20', '20', '20', '20', '30', '20'], ['30', '20', '30', '50', '10', '30', '20', '20', '20'], ['100', '100'], ['100', '100', '100', '100', '100'], ['100', '100', '100', '100']]
>>> pprint(l)
[['40', '20', '10', '30'],
['20', '20', '20', '20', '20', '30', '20'],
['30', '20', '30', '50', '10', '30', '20', '20', '20'],
['100', '100'],
['100', '100', '100', '100', '100'],
['100', '100', '100', '100']]
>>> float_l = [map(float, nested_list) for nested_list in l]
>>> pprint(float_l)
[[40.0, 20.0, 10.0, 30.0],
[20.0, 20.0, 20.0, 20.0, 20.0, 30.0, 20.0],
[30.0, 20.0, 30.0, 50.0, 10.0, 30.0, 20.0, 20.0, 20.0],
[100.0, 100.0],
[100.0, 100.0, 100.0, 100.0, 100.0],
[100.0, 100.0, 100.0, 100.0]]
You can use
string wanted_path = Path.GetDirectoryName(Path.GetDirectoryName(System.IO.Directory.GetCurrentDirectory()));
In your cmd type command
python manage.py findstatic --verbosity 2 static
It will give the directory in which Django is looking for static files.If you have created a virtual environment then there will be a static folder inside this virtual_environment_name folder.
VIRTUAL_ENVIRONMENT_NAME\Lib\site-packages\django\contrib\admin\static
.
On running the above 'findstatic' command if Django shows you this path then just paste all your static files in this static directory.
In your html file use JINJA syntax for href and check for other inline css. If still there is an image src or url after giving JINJA syntax then prepend it with '/static'.
This worked for me.
You can't. Variables defined inside a method are local to that method.
If you want to share variables between methods, then you'll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn't always applicable).
Looks like you're using instance methods instead of static ones.
If you don't want to create an object, you should declare all your methods static, so something like
private static void methodName(Argument args...)
If you want a variable to be accessible by all these methods, you should initialise it outside the methods and to limit its scope, declare it private.
private static int[][] array = new int[3][5];
Global variables are usually looked down upon (especially for situations like your one) because in a large-scale program they can wreak havoc, so making it private will prevent some problems at the least.
Also, I'll say the usual: You should try to keep your code a bit tidy. Use descriptive class, method and variable names and keep your code neat (with proper indentation, linebreaks etc.) and consistent.
Here's a final (shortened) example of what your code should be like:
public class Test3 {
//Use this array in your methods
private static int[][] scores = new int[3][5];
/* Rather than just "Scores" name it so people know what
* to expect
*/
private static void createScores() {
//Code...
}
//Other methods...
/* Since you're now using static methods, you don't
* have to initialise an object and call its methods.
*/
public static void main(String[] args){
createScores();
MD(); //Don't know what these do
sumD(); //so I'll leave them.
}
}
Ideally, since you're using an array, you would create the array in the main method and pass it as an argument across each method, but explaining how that works is probably a whole new question on its own so I'll leave it at that.
Two problems- List is empty. You need to add some buttons to the list first. Second problem: You can't add buttons to "this". "This" is not referencing what you think, I think. Change this to reference a Panel for instance.
//Assume you have on your .aspx page:
<asp:Panel ID="Panel_Controls" runat="server"></asp:Panel>
private void button1_Click(object sender, EventArgs e)
{
List<Button> buttons = new List<Button>();
for (int i = 0; i < buttons.Capacity; i++)
{
Panel_Controls.Controls.Add(buttons[i]);
}
}
Dec 10th 2019, Xcode Version 11.2.1, MacOS X 10.15.1
I was facing exactly same issue yesterday and I thought it might be network issues, at least it looks like so. But this morning I had tried couple different networks and several VPN connections, none of them is working!
The highest voted answer here asks me to reset a cache folder named .itmstransporter under my home dir, the run a program iTMSTransporter under a specific folder, but I can't find both of them.
But soon I figured that it is the cache folder for the people who uses the legacy uploader program: Application Loader, which is deprecated by Apple and can be no longer found in Xcode 11. Then I found that the latest Xcode has located iTMSTransporter here:
/Applications/Xcode.app/Contents/SharedFrameworks/ContentDeliveryServices.framework/itms/bin/iTMSTransporter
And its cache folder is here:
/Users/your_user_name/Library/Caches/com.apple.amp.itmstransporter/
I removed my existed cache folder, and run iTMSTransporter without any parameter, it soon started to output logs and download a bunch of files, and finished in 2 or 3 minutes. Then I tried again to upload my ipa file, it works!!!
CONCLUTION:
Yes, it is normal. This is because you checkout a single commit, that doesnt have a head. Especially it is (sooner or later) not a head of any branch.
But there is usually no problem with that state. You may create a new branch from the tag, if this makes you feel safer :)
Had the same problem running PHP 7.2. I had to do the following :
sudo apt-get install php7.2-xml
Try c.ToString("F6");
(For a full explanation of numeric formatting, see MSDN)
Option 1:
Use pandas
dataframe plot (built on top of matplotlib
):
import pandas as pd
data = [1.5]*7 + [2.5]*2 + [3.5]*8 + [4.5]*3 + [5.5]*1 + [6.5]*8
pd.DataFrame(data).plot(kind='density') # or pd.Series()
Option 2:
Use distplot
of seaborn
:
import seaborn as sns
data = [1.5]*7 + [2.5]*2 + [3.5]*8 + [4.5]*3 + [5.5]*1 + [6.5]*8
sns.distplot(data, hist=False)
For those who need save objects like {foo: 'bar'}, I share my edited version of @KevinBurke's answer. I've added JSON.stringify and JSON.parse, that's all.
cookie = {
set: function (name, value, days) {
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
var expires = "; expires=" + date.toGMTString();
}
else
var expires = "";
document.cookie = name + "=" + JSON.stringify(value) + expires + "; path=/";
},
get : function(name){
var nameEQ = name + "=",
ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0)
return JSON.parse(c.substring(nameEQ.length,c.length));
}
return null;
}
}
So, now you can do things like this:
cookie.set('cookie_key', {foo: 'bar'}, 30);
cookie.get('cookie_key'); // {foo: 'bar'}
cookie.set('cookie_key', 'baz', 30);
cookie.get('cookie_key'); // 'baz'
Ok I did it with some trick ;) First build a UITextField
and increased it's size
like this :
CGRect frameRect = textField.frame;
frameRect.size.height = 53;
textField.frame = frameRect;
Then build a UITextView
exactly in the same area that u made my UITextField
, and deleted its background color
. Now it looks like that u have a multiple lines TextField
!
You could use querySelector()
with attribute selector '[attribute="value"]'
, then affect css rule using .style
, as you can see in the example below:
document.querySelector('a[aria-expanded="true"]').style.backgroundColor = "#42DCA3";
_x000D_
<ul><li class="active">_x000D_
<a href="#3a" class="btn btn-default btn-lg" data-toggle="tab" aria-expanded="true"> <span class="network-name">Google+ with aria expanded true</span></a>_x000D_
</li>_x000D_
<li>_x000D_
<a href="#3a" class="btn btn-default btn-lg" data-toggle="tab" aria-expanded="false"> <span class="network-name">Google+ with aria expanded false</span></a>_x000D_
</li>_x000D_
</ul>
_x000D_
jQuery solution :
If you want to use a jQuery solution you could simply use css()
method :
$('a[aria-expanded="true"]').css('background-color','#42DCA3');
Hope this helps.
Also seems nobody noticed -x operator on symlinks. A symlink (chain) to a regular file (not classified as executable) fails the test.
In Oracle database we can achieve like this.
CREATE TABLE Student(
StudentID Number(38, 0) not null,
DepartmentID Number(38, 0) not null,
PRIMARY KEY (StudentID, DepartmentID)
);
foreach
:
foreach (var money in myMoney) {
Console.WriteLine("Amount is {0} and type is {1}", money.amount, money.type);
}
Alternatively, because it is a List<T>
.. which implements an indexer method []
, you can use a normal for
loop as well.. although its less readble (IMO):
for (var i = 0; i < myMoney.Count; i++) {
Console.WriteLine("Amount is {0} and type is {1}", myMoney[i].amount, myMoney[i].type);
}
If you don't want to lose the columns you shift past the end of your dataframe, simply append the required number first:
offset = 5
DF = DF.append([np.nan for x in range(offset)])
DF = DF.shift(periods=offset)
DF = DF.reset_index() #Only works if sequential index
please set dataType config property in your ajax call and give it another try!
another point is you are using ajax call setup configuration properties as string and it is wrong as reference site
$.ajax({
url : 'http://voicebunny.comeze.com/index.php',
type : 'GET',
data : {
'numberOfWords' : 10
},
dataType:'json',
success : function(data) {
alert('Data: '+data);
},
error : function(request,error)
{
alert("Request: "+JSON.stringify(request));
}
});
I hope be helpful!
Set textbox with and maxlength in mvc3.0
@Html.TextBoxFor(model => model.SearchUrl, new { style = "width:650px;",maxlength = 250 })
Use the -s
or --strategy
option combined with the -X
option. In your specific question, you want to keep all of the remote files and replace the local files of the same name.
Replace conflicts with the remote version
git merge -s recursive -Xtheirs upstream/master
will use the remote repo version of all conflicting files.
Replace conflicts with the local version
git merge -s recursive -Xours upstream/master
will use the local repo version of all conflicting files.
Android studio is based on Intellij Idea. In Intellij Idea you have to do the following from the GUI menu.

You can solve this problem by placing XML in the same directory in which your main python file (from where you tried to include this file) was placed. Now the next step is to use full path. For example
This will not work
front_cascade = cv2.CascadeClassifier('./haarcascade_eye.xml')
Use full path, now it will work fine
front_cascade = cv2.CascadeClassifier('/Users/xyz/Documents/project/haarcascade_eye.xml')
A similar question is here: Is there a limit to the length of a GET request?
I've hit the limit and on my shared hosting account, but the browser returned a blank page before it got to the server I think.
Also, you can just set the ViewName:
return View("ViewName");
Full controller example:
public ActionResult SomeAction() {
if (condition)
{
return View("CustomView");
}else{
return View();
}
}
This works on MVC 5.

What I usually do is the following: a Gradle Clean
, Rebuild
and Sync all my Gradle files
. After that I restart
Android Studio, and I go to:
Select Theme -> Project Themes -> AppTheme
there are major 4 steps
1. copy the .android folder to your desired location as i did in D:\Android\.android
2. set ANDROID_AVD_HOME in environment variables like ANDROID_AVD_HOME
D:\Android\.android\avd
3. change avd name.ini file contents with new location like
avd.ini.encoding=UTF-8
path=D:\Android\.android\avd\Pixel_2_API_29.avd
path.rel=avd\Pixel_2_API_29.avd
target=android-29
4. restart android studio
I think you mean
cast(floor(cast(getdate()as float))as datetime)
real is only 32-bits, and could lose some information
This is fastest
cast(cast(getdate()+x-0.5 as int)as datetime)
...though only about 10% faster(about 0.49 microseconds CPU vs. 0.58)
This was recommended, and takes the same time in my test just now:
DATEADD(dd, DATEDIFF(dd, 0, getdate()), 0)
In SQL 2008, the SQL CLR function is about 5 times faster than using a SQL function would be, at 1.35 microseconds versus 6.5 microsections, indicating much lower function-call overhead for a SQL CLR function versus a simple SQL UDF.
In SQL 2005, the SQL CLR function is 16 times faster, per my testing, versus this slow function:
create function dateonly ( @dt datetime )
returns datetime
as
begin
return cast(floor(cast(@dt as float))as int)
end
Mysql isn't very clever. When you want to use the same timestamp in multiple update or insert queries, you need to declare a variable.
When you use the now()
function, the system will call the current timestamp every time you call it in another query.
Note that this behavior is the default (ANSI) behavior.
If you:
SET ANSI_NULLS OFF
http://msdn.microsoft.com/en-us/library/ms188048.aspx
You'll get different results.
SET ANSI_NULLS OFF
will apparently be going away in the future...
You should use the to_date
function (oracle/functions/to_date.php
)
SELECT * FROM MYTABLE WHERE MYTABLE.DATEIN = TO_DATE('23/04/49', 'DD/MM/YY');
mysqli_error
function requires $myConnection

You need to put UTF-8 in quotes
You have $headers .= '...';
followed by $headers = '...';
; the second line is overwriting the first.
Just put the $headers .= "Bcc: $emailList\r\n";
say after the Content-type
line and it should be fine.
On a side note, the To
is generally required; mail servers might mark your message as spam otherwise.
$headers = "From: [email protected]\r\n" .
"X-Mailer: php\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$headers .= "Bcc: $emailList\r\n";
Outer classes cannot be static, but nested/inner classes can be. That basically helps you to use the nested/inner class without creating an instance of the outer class.
Starting from Java 10:
Set<E> oldSet = Set.of();
Set<E> newSet = Set.copyOf(oldSet);
Set.copyOf()
returns an unmodifiable Set
containing the elements of the given Collection
.
The given Collection
must not be null
, and it must not contain any null
elements.
Interfaces are abstract sets of defined available functionality.
Whether or not a method in that interface behaves as static or not is an implementation detail that should be hidden behind the interface. It would be wrong to define an interface method as static because you would be unnecessarily forcing the method to be implemented in a certain way.
If methods were defined as static, the class implementing the interface wouldn't be as encapsulated as it could be. Encapsulation is a good thing to strive for in object oriented design (I won't go into why, you can read that here: http://en.wikipedia.org/wiki/Object-oriented). For this reason, static methods aren't permitted in interfaces.
How to get rid of a header(first row) and an index(first column).
To write to CSV file:
df = pandas.DataFrame(your_array)
df.to_csv('your_array.csv', header=False, index=False)
To read from CSV file:
df = pandas.read_csv('your_array.csv')
a = df.values
If you want to read a CSV file that doesn't contain a header, pass additional parameter header
:
df = pandas.read_csv('your_array.csv', header=None)

Please open the system display settings and ensure that font size is set to 100% It worked surprisingly
This would be easier to do with flexbox. Using flexbox will let you not to specify the height of your content and can adjust automatically on the height it contains.

Only use WOFF2, or if you need legacy support, WOFF. Do not use any other format
(svg
and eot
are dead formats, ttf
and otf
are full system fonts, and should not be used for web purposes)
In short, font-face is very old, but only recently has been supported by more than IE.
eot
is needed for Internet Explorers that are older than IE9 - they invented the spec, but eot was a proprietary solution.
ttf
and otf
are normal old fonts, so some people got annoyed that this meant anyone could download expensive-to-license fonts for free.
Time passes, SVG 1.1 adds a "fonts" chapter that explains how to model a font purely using SVG markup, and people start to use it. More time passes and it turns out that they are absolutely terrible compared to just a normal font format, and SVG 2 wisely removes the entire chapter again.
Then, woff
gets invented by people with quite a bit of domain knowledge, which makes it possible to host fonts in a way that throws away bits that are critically important for system installation, but irrelevant for the web (making people worried about piracy happy) and allows for internal compression to better suit the needs of the web (making users and hosts happy). This becomes the preferred format.
2019 edit A few years later, woff2
gets drafted and accepted, which improves the compression, leading to even smaller files, along with the ability to load a single font "in parts" so that a font that supports 20 scripts can be stored as "chunks" on disk instead, with browsers automatically able to load the font "in parts" as needed, rather than needing to transfer the entire font up front, further improving the typesetting experience.
If you don't want to support IE 8 and lower, and iOS 4 and lower, and android 4.3 or earlier, then you can just use WOFF (and WOFF2, a more highly compressed WOFF, for the newest browsers that support it.)
@font-face {
font-family: 'MyWebFont';
src: url('myfont.woff2') format('woff2'),
url('myfont.woff') format('woff');
}
Support for woff
can be checked at http://caniuse.com/woff

from lemiorhan example i can solve with just change some line of lemiorhan's code use:
JSONObject json = new JSONObject(obj);
instead of this:
JSONObject json = (JSONObject) obj
so in my test code is :
Map item_sub2 = new LinkedHashMap();
item_sub2.put("name", "flare");
item_sub2.put("val1", "val1");
item_sub2.put("val2", "val2");
item_sub2.put("size",102);
JSONArray itemarray2 = new JSONArray();
itemarray2.add(item_sub2);
itemarray2.add(item_sub2);//just for test
itemarray2.add(item_sub2);//just for test
Map item_sub1 = new LinkedHashMap();
item_sub1.put("name", "flare");
item_sub1.put("val1", "val1");
item_sub1.put("val2", "val2");
item_sub1.put("children",itemarray2);
JSONArray itemarray = new JSONArray();
itemarray.add(item_sub1);
itemarray.add(item_sub1);//just for test
itemarray.add(item_sub1);//just for test
Map item_root = new LinkedHashMap();
item_root.put("name", "flare");
item_root.put("children",itemarray);
JSONObject json = new JSONObject(item_root);
System.out.println(json.toJSONString());
I prefered to use an expression. This lets me do stuff like focus on a button when a field is valid, reaches a certain length, and of course after load.
<button type="button" moo-focus-expression="form.phone.$valid">
<button type="submit" moo-focus-expression="smsconfirm.length == 6">
<input type="text" moo-focus-expression="true">
On a complex form this also reduces need to create additional scope variables for the purposes of focusing.
Marius's answer worked perfectly for me:
df.reset_index() sets the index as the first column, with the column label "index." You can now use the index as an axis for plotting, as described in his answer:
monthly_mean.reset_index().plot(x='index', y='A')
However, this does not change the original dataframe. The original dataframe will be unchanged unless it is set using df = df.reset_index().
example:
df.reset_index()
print(df)

The reason may be that watcher is declared as local variable to a method and it is garbage collected when the method finishes. You should declare it as a class member. Try the following:
FileSystemWatcher watcher;
private void watch()
{
watcher = new FileSystemWatcher();
watcher.Path = path;
watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
| NotifyFilters.FileName | NotifyFilters.DirectoryName;
watcher.Filter = "*.*";
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.EnableRaisingEvents = true;
}
private void OnChanged(object source, FileSystemEventArgs e)
{
//Copies file to another directory.
}
A lot of the answers above (and on duplicates of this question) rely on installed.packages
which is bad form. From the documentation:
This can be slow when thousands of packages are installed, so do not use this to find out if a named package is installed (use system.file or find.package) nor to find out if a package is usable (call require and check the return value) nor to find details of a small number of packages (use packageDescription). It needs to read several files per installed package, which will be slow on Windows and on some network-mounted file systems.
So, a better approach is to attempt to load the package using require
and and install if loading fails (require
will return FALSE
if it isn't found). I prefer this implementation:
using<-function(...) {
libs<-unlist(list(...))
req<-unlist(lapply(libs,require,character.only=TRUE))
need<-libs[req==FALSE]
if(length(need)>0){
install.packages(need)
lapply(need,require,character.only=TRUE)
}
}
which can be used like this:
using("RCurl","ggplot2","jsonlite","magrittr")
This way it loads all the packages, then goes back and installs all the missing packages (which if you want, is a handy place to insert a prompt to ask if the user wants to install packages). Instead of calling install.packages
separately for each package it passes the whole vector of uninstalled packages just once.
Here's the same function but with a windows dialog that asks if the user wants to install the missing packages
using<-function(...) {
libs<-unlist(list(...))
req<-unlist(lapply(libs,require,character.only=TRUE))
need<-libs[req==FALSE]
n<-length(need)
if(n>0){
libsmsg<-if(n>2) paste(paste(need[1:(n-1)],collapse=", "),",",sep="") else need[1]
print(libsmsg)
if(n>1){
libsmsg<-paste(libsmsg," and ", need[n],sep="")
}
libsmsg<-paste("The following packages could not be found: ",libsmsg,"\n\r\n\rInstall missing packages?",collapse="")
if(winDialog(type = c("yesno"), libsmsg)=="YES"){
install.packages(need)
lapply(need,require,character.only=TRUE)
}
}
}
ALTER TABLE MyTable MODIFY Col3 varchar(20) NULL;
What you're looking for is the function strlcpy()
which does terminate always the string with 0 and initializes the buffer. It also is able to detect overflows. Only problem, it's not (really) portable and is present only on some systems (BSD, Solaris). The problem with this function is that it opens another can of worms as can be seen by the discussions on
http://en.wikipedia.org/wiki/Strlcpy
My personal opinion is that it is vastly more useful than strncpy()
and strcpy()
. It has better performance and is a good companion to snprintf()
. For platforms which do not have it, it is relatively easy to implement.
(for the developement phase of a application I substitute these two function (snprintf()
and strlcpy()
) with a trapping version which aborts brutally the program on buffer overflows or truncations. This allows to catch quickly the worst offenders. Especially if you work on a codebase from someone else.
EDIT: strlcpy()
can be implemented easily:
size_t strlcpy(char *dst, const char *src, size_t dstsize)
{
size_t len = strlen(src);
if(dstsize) {
size_t bl = (len < dstsize-1 ? len : dstsize-1);
((char*)memcpy(dst, src, bl))[bl] = 0;
}
return len;
}

For those looking for a solution. If you accidentally made pip
requirements with pip list
instead of pip freeze
, and want to convert into pip freeze format. I wrote this R script to do so.
library(tidyverse)
pip_list = read_lines("requirements.txt")
pip_freeze = pip_list %>%
str_replace_all(" \\(", "==") %>%
str_replace_all("\\)$", "")
pip_freeze %>% write_lines("requirements.txt")
Also struggled with this issue, trying to upload .csv data into AWS RDS instance from my local machine using MySQL Workbench on Windows.
The addition I needed was adding OPT_LOCAL_INFILE=1
in: Connection > Advanced > Others. Note CAPS was required.
I found this answer by PeterMag in AWS Developer Forums.
For further info:
SHOW VARIABLES LIKE 'local_infile';
already returned ON
and the query was:
LOAD DATA LOCAL INFILE 'filepath/file.csv'
INTO TABLE `table_name`
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 ROWS;
Copying from the answer source referenced above:
Apparently this is a bug in MYSQL Workbench V8.X. In addition to the configurations shown earlier in this thread, you also need to change the MYSQL Connection in Workbench as follows:
- Go to the Welcome page of MYSQL which displays all your connections
- Select Manage Server Connections (the little spanner icon)
- Select your connection
- Select Advanced tab
- In the Others box, add OPT_LOCAL_INFILE=1
Now I can use the LOAD DATA LOCAL INFILE query on MYSQL RDS. It seems that the File_priv permission is not required.*
The command explains itself quite well. It's to figure out which co-worker wrote the specific line or ruined the project, so you can blame them :)
SqlConnection c = new SqlConnection(@"Data Source=localhost;
Initial Catalog=Northwind; Integrated Security=True");
Here is an example using a 3rd party wrapper library for Vue called vue-moment
.
In addition to binding Moment instance into Vue's root scope, this library includes moment
and duration
filters.
This example includes localization and is using ES6 module imports, an official standard, instead of NodeJS's CommonJS module system requires.
import Vue from 'vue';
import moment from 'moment';
import VueMoment from 'vue-moment';
// Load Locales ('en' comes loaded by default)
require('moment/locale/es');
// Choose Locale
moment.locale('es');
Vue.use(VueMoment, { moment });
Now you can use the Moment instance directly in your Vue templates without any additional markup:
<small>Copyright {{ $moment().year() }}</small>
Or the filters:
<span>{{ 3600000 | duration('humanize') }}</span>
<!-- "an hour" -->
<span>{{ [2, 'years'] | duration('add', 1, 'year') | duration('humanize') }}</span>
<!-- "3 years" -->
Try to use JSONP
in your Ajax call. It will bypass the Same Origin Policy.
http://learn.jquery.com/ajax/working-with-jsonp/
Try example
$.ajax({
url: "https://api.dailymotion.com/video/x28j5hv?fields=title",
dataType: "jsonp",
success: function( response ) {
console.log( response ); // server response
}
});
Expanding on what Mark Elliot said earlier, the easiest way to get the size of a 2D array given that each array in the array of arrays is of the same size is:
array.length * array[0].length
If this is just for debugging output, you can use the following to see all the types and values as well.
var_dump($obj);
If you want more control over the output you can use this:
foreach ($obj as $key => $value) {
echo "$key => $value\n";
}
To print to any printer on the network you can send a PJL/PCL print job directly to a network printer on port 9100.
Please have a look at the below link that should give a good start:
http://frank.zinepal.com/printing-directly-to-a-network-printer
Also, If there is a way to call Windows cmd you can use FTP put to print your page on 9100. Below link should give you details, I have used this method for HP printers but I believe it will work for other printers.

In a debug compilation, Assert
takes in a Boolean condition as a parameter, and shows the error dialog if the condition is false. The program proceeds without any interruption if the condition is true.
If you compile in Release, all Debug.Assert
's are automatically left out.
The Philippe solution but cleaner:
My subtraction data is: '2018-09-22T11:05:00.000Z'
import datetime
import pandas as pd
df_modified = pd.to_datetime(df_reference.index.values) - datetime.datetime(2018, 9, 22, 11, 5, 0)
The problem is likely to lie with the line:
window.onload = onPageLoad();
By including the brackets you are saying onload
should equal the return value of onPageLoad()
. For example:
/*Example function*/
function onPageLoad()
{
return "science";
}
/*Set on load*/
window.onload = onPageLoad()
If you print out the value of window.onload
to the console it will be:
science
The solution is remove the brackets:
window.onload = onPageLoad;
So, you're using onPageLoad
as a reference to the so-named function.
Finally, in order to get the response value you'll need a readystatechange
listener for your XMLHttpRequest
object, since it's asynchronous:
xmlDoc = xmlhttp.responseXML;
parser = new DOMParser(); // This code is untested as it doesn't run this far.
Here you add the listener:
xmlHttp.onreadystatechange = function() {
if(this.readyState == 4) {
// Do something
}
}
you can use a stackLayout, inside of this layout you can put a list a frame, for example:
<StackLayout VerticalOptions="FillAndExpand">
<ListView ItemsSource="{Binding YourList}"
CachingStrategy="RecycleElement"
HasUnevenRows="True">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell >
<StackLayout Orientation="Horizontal">
<Label Text="{Binding Image, Mode=TwoWay}" />
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
<Frame BackgroundColor="AliceBlue" HorizontalOptions="FillAndExpand">
<Button Text="More"></Button>
</Frame>
</StackLayout>
this is the result:
Try this
public static void main(String[] args)
{
String original = "ABCDEFGHIJKLMNOPQ";
String tobeChecked = "GHi";
System.out.println(containsString(original, tobeChecked, true));
System.out.println(containsString(original, tobeChecked, false));
}
public static boolean containsString(String original, String tobeChecked, boolean caseSensitive)
{
if (caseSensitive)
{
return original.contains(tobeChecked);
}
else
{
return original.toLowerCase().contains(tobeChecked.toLowerCase());
}
}
Using LD_PRELOAD
path, you can force the application loader to load provided shared object, over the default provided.
Developers uses this to debug their applications by providing different versions of the shared objects.
We've used it to hack certain applications, by overriding existing functions using prepared shared objects.
You can also manually change the time part of date and format in "dd/mm/yyyy" pattern according to your requirement.
public static Date getZeroTimeDate(Date changeDate){
Date returnDate=new Date(changeDate.getTime()-(24*60*60*1000));
return returnDate;
}
If the return value is not working then check for the context parameter in web.xml. eg.
<context-param>
<param-name>javax.faces.DATETIMECONVERTER_DEFAULT_TIMEZONE_IS_SYSTEM_TIMEZONE</param-name>
<param-value>true</param-value>
</context-param>

Assuming you're using Spring Boot, another option is to put the following in your application.properties
:
logging.level.org.springframework.security=DEBUG
This is the same for most other Spring modules as well.
If you're not using Spring Boot, try setting the property in your logging configuration, e.g. logback.
Here is the application.yml version as well:
logging:
level:
org:
springframework:
security: DEBUG
If you don't feel like changing your MySQL configuration you could use an SQL profiler like "Neor Profile SQL" http://www.profilesql.com .
In the directories are also many binary files. I can't search only certain directories (the directory structure is a big mess). Is there's a better way of grepping only in certain files?
ripgrep
This is one of the quickest tools designed to recursively search your current directory. It is written in Rust, built on top of Rust's regex engine for maximum efficiency. Check the detailed analysis here.
So you can just run:
rg "some_pattern"
It respect your .gitignore
and automatically skip hidden files/directories and binary files.
You can still customize include or exclude files and directories using -g
/--glob
. Globbing rules match .gitignore
globs. Check man rg
for help.
For more examples, see: How to exclude some files not matching certain extensions with grep?
On macOS, you can install via brew install ripgrep
.
As of 2019, this works (in Chrome at least)
$(document).keypress(function(e) {
var key = (event.which || event.keyCode) ;
if(e.ctrlKey) {
if (key == 26) { console.log('Ctrl+Z was pressed') ; }
else if (key == 25) { console.log('Ctrl+Y was pressed') ; }
else if (key == 19) { console.log('Ctrl+S was pressed') ; }
else { console.log('Ctrl', key, 'was pressed') ; }
}
});
if @simon's answer is not working in some of the mac's please follow the below process.
If you have already installed swiftgen using the following commands:
$ brew update
$ brew install swiftgen
then follow the steps below in order to run swiftgen with older version.
Step 1: brew uninstall swiftgen
Step 2: Navigate to: https://github.com/SwiftGen/SwiftGen/releases
and download the swiftgen with version: swiftgen-4.2.0.zip.
Unzip the package in any of the directories.
Step 3: Execute the following in a terminal:
$ mkdir -p ~/dependencies/swiftgen
$ cp -R ~/<your_directory_name>/swiftgen-4.2.0/ ~/dependencies/swiftgen
$ cd /usr/local/bin
$ ln -s ~/dependencies/swiftgen/bin/swiftgen swiftgen
$ mkdir ~/Library/Application\ Support/SwiftGen
$ ln -s ~/dependencies/swiftgen/templates/ ~/Library/Application\ Support/SwiftGen/
$ swiftgen --version
You should get: SwiftGen v0.0 (Stencil v0.8.0, StencilSwiftKit v1.0.0, SwiftGenKit v1.0.1)
As stated in an article by Slicehost:
User setup
So let's start by adding the main user to the Apache user group:
sudo usermod -a -G www-data demo
That adds the user 'demo' to the 'www-data' group. Do ensure you use both the -a and the -G options with the usermod command shown above.
You will need to log out and log back in again to enable the group change.
Check the groups now:
groups ... # demo www-data
So now I am a member of two groups: My own (demo) and the Apache group (www-data).
Folder setup
Now we need to ensure the public_html folder is owned by the main user (demo) and is part of the Apache group (www-data).
Let's set that up:
sudo chgrp -R www-data /home/demo/public_html
As we are talking about permissions I'll add a quick note regarding the sudo command: It's a good habit to use absolute paths (/home/demo/public_html) as shown above rather than relative paths (~/public_html). It ensures sudo is being used in the correct location.
If you have a public_html folder with symlinks in place then be careful with that command as it will follow the symlinks. In those cases of a working public_html folder, change each folder by hand.
Setgid
Good so far, but remember the command we just gave only affects existing folders. What about anything new?
We can set the ownership so anything new is also in the 'www-data' group.
The first command will change the permissions for the public_html directory to include the "setgid" bit:
sudo chmod 2750 /home/demo/public_html
That will ensure that any new files are given the group 'www-data'. If you have subdirectories, you'll want to run that command for each subdirectory (this type of permission doesn't work with '-R'). Fortunately new subdirectories will be created with the 'setgid' bit set automatically.
If we need to allow write access to Apache, to an uploads directory for example, then set the permissions for that directory like so:
sudo chmod 2770 /home/demo/public_html/domain1.com/public/uploads
The permissions only need to be set once as new files will automatically be assigned the correct ownership.
Try using the following commands
//For make issues
sudo apt-get install build-essential
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.4/install.sh | bash
//To uninstall a node version
nvm uninstall <current version>
nvm install 6.10.3
nvm use 6.10.3
//check with
node -v
How about: hasattr(a, "__iter__")
?
It tells if the object returned can be iterated over as a generator. By default, tuples and lists can, but not the string types.
For multiline text the left and the right margin can be set by using NSAttributedString.
NSMutableParagraphStyle *style = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
style.alignment = NSTextAlignmentJustified;
style.firstLineHeadIndent = 10.0f;
style.headIndent = 10.0f;
style.tailIndent = -10.0f;
NSAttributedString *attrText = [[NSAttributedString alloc] initWithString:title attributes:@{ NSParagraphStyleAttributeName : style}];
UILabel * label = [[UILabel alloc] initWithFrame:someFrame];
label.numberOfLines = 0;
label.attributedText = attrText;
Here is the above example adopted to Swift 5:
extension UILabel {
func setMargins(margin: CGFloat = 10) {
if let textString = self.text {
var paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.firstLineHeadIndent = margin
paragraphStyle.headIndent = margin
paragraphStyle.tailIndent = -margin
let attributedString = NSMutableAttributedString(string: textString)
attributedString.addAttribute(.paragraphStyle, value: paragraphStyle, range: NSRange(location: 0, length: attributedString.length))
attributedText = attributedString
}
}
}
The best way to solve your problem is to set the UseSystemPasswordChar
property to true. Then, the Caps-lock message is shown when the user enters the field and the Caps-Lock is on (at least for Vista and Windows 7).
Another alternative is to set the PasswordChar
property to a character value (* for example). This also triggers the automatic Caps-Lock handling.
You can use arguments with default values.
def someMethod(def mandatory,def optional=null){}
if argument "optional" not exist, it turns to "null".
A one-line approach:
var jsonData = Ext.encode(Ext.pluck(store.data.items, 'data'));
Not very pretty, but quite short.
These 2 methods I tried are not working:
sudo npm cache clean -f
sudo npm install -g n
sudo n stable
After trying, node -v
still shows the old version of node.
Below method works for me:
Step 1: Install nvm (for more details: https://github.com/creationix/nvm#installation)
Open terminal and type this command:
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
Close terminal and reopen it.
Type this command to check if nvm is installed:
command -v nvm
Step 2: To download, compile, and install the latest release of node, type this:
nvm install node
("node" is an alias for the latest version)
To check if node gets the latest version (v10.11.0).
Installing the latest node also installs the latest npm.
Check if npm gets the latest version (6.4.1).
use
=VLOOKUP(D4,F4:G9,2)
with the range F4:G9:
0 0.1
1 0.15
5 0.2
15 0.3
30 1
100 1.3
and D4
being the value in question, e.g. 18.75
-> result: 0.3
You first need to add the package database and add the PGP key.
Run the following.
#add pgp key
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
#add package file
echo "deb http://repo.mongodb.org/apt/ubuntu "$(lsb_release -sc)"/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list
#update package list
sudo apt-get update
#install mongo
sudo apt-get install -y mongodb-org
If you're willing to "take this to the console", I'd recommend enca
. Unlike the rather simplistic mb_detect_encoding
, it uses "a mixture of parsing, statistical analysis, guessing and black magic to determine their encodings" (lol - see man page). However, you usually have to pass the language of the input file if you want to detect such country-specific encodings. (However, mb_detect_encoding
essentially has the same requirement, as the encoding would have to appear "in the right place" in the list of passed encodings for it to be detectable at all.)

You should be able to use a command like this on ubuntu to gather the source for a package, you can omit sudo
assuming your downloading to a location you own.
data1.reset_index(inplace=True)
The commented out version is the more correct way to do this.
If you use the ==
operator on strings, you're comparing the strings' addresses (where they're allocated in memory) rather than the values of the strings. This is very occasional useful (it indicates you have the exact same string object), but 99% of the time you want to compare the values, which you do like so:
if([myT isEqualToString:@"10"] || [myT isEqualToString:@"11"] || [myT isEqualToString:@"12"])
In Swift for any kind of UIViewController:
In your AppDelegate
set:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
window!.rootViewController = myRootController
return true
}
myRootController
can be any kind of UIViewController
, e.g. UITabBarController
or UINavigationController
.
Then, override this root controller like this:
class RootController: UIViewController {
override func preferredStatusBarStyle() -> UIStatusBarStyle {
return .LightContent
}
}
This will change the appearance of the status bar in your whole app, because the root controller is solely responsible for the status bar appearance.
Remember to set the property View controller-based status bar appearance
to YES in your Info.plist
to make this work (which is the default).

One option is to have the page be blank, containing a small amount of javascript. Use the script to make an AJAX call to get the actual page content, and have the success function write the result over the current document. In the timeout function you can "do something else amazing"
Approximate pseudocode:
$(document).ready(function(){
$.ajax
url of actual page
success:do something amazing
timeout: do something else
});

Yes, in VS2010 they changed this behavior somewhy.
Open your project and navigate to the following menu: Project -> YourProjectName Properties -> Configuration Properties -> Linker -> System. There in the field SubSystem use the drop-down to select Console (/SUBSYSTEM:CONSOLE) and apply the change.
"Start without debugging" should do the right thing now.
Or, if you write in C++ or in C, put
system("pause");
at the end of your program, then you'll get "Press any key to continue..." even when running in debug mode.
@DanielChapman gives a good explanation of serialVersionUID, but no solution. the solution is this: run the serialver
program on all your old classes. put these serialVersionUID
values in your current versions of the classes. as long as the current classes are serial compatible with the old versions, you should be fine. (note for future code: you should always have a serialVersionUID
on all Serializable
classes)
if the new versions are not serial compatible, then you need to do some magic with a custom readObject
implementation (you would only need a custom writeObject
if you were trying to write new class data which would be compatible with old code). generally speaking adding or removing class fields does not make a class serial incompatible. changing the type of existing fields usually will.
Of course, even if the new class is serial compatible, you may still want a custom readObject
implementation. you may want this if you want to fill in any new fields which are missing from data saved from old versions of the class (e.g. you have a new List field which you want to initialize to an empty list when loading old class data).
Here is a slightly simpler version that I found. It reads the entire file in one go and only requires a single using
directive.
byte[] ComputeHash(string filePath)

using (var md5 = MD5.Create())
{
return md5.ComputeHash(File.ReadAllBytes(filePath));

Use a custom comparator:
Collections.sort(nodeList, new Comparator<DataNode>(){
public int compare(DataNode o1, DataNode o2){
if(o1.degree == o2.degree)
return 0;

In /etc/profile , if you open that will you’ll get to know that IT IS no recommended to write on that file. Instead of that make a script of your commands(suppose test.sh)go to /etc/profile.d folder and Put test.sh there. Every time you instance reboot it’ll be automatically called by /etc/profile.
Something like this should work (untested code warning):
<?php
$html = '<p style="asd">qwe</p><br /><p class="qwe">qweqweqwe</p>';
$domd = new DOMDocument();
libxml_use_internal_errors(true);
$domd->loadHTML($html);
libxml_use_internal_errors(false);
$domx = new DOMXPath($domd);
$items = $domx->query("//p[@style]");
foreach($items as $item) {
$item->removeAttribute("style");
}
echo $domd->saveHTML();
var height = document.body.clientHeight;
var width = document.body.clientWidth;

If you want to make sure your android client application is logged out from some server before your Activity gets killed --> log out with a service on its own thread (that's what you're supposed to do anyway).
Disabling the back button won't solve anything for you. You'll still have the same problem when the user receives a phone call for instance. When a phone call is received, your activity has about as much chances of getting killed before it gets a reliable answer back from the network.
That's why you should let a service wait on its own thread for the answer from the network, and then make it try again if it doesn't succeed. The android service is not only much less likely to get killed before it gets an answer back, but should it really get killed before finishing the job, it can always get revived by AlarmManager to try again.

/// The template is changed in memory and a copy of it is sent to
/// the user computer through a file stream.
/// </summary>
/// <returns>Excel report</returns>
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult NPOICreate()
{
try
{
// Opening the Excel template...
FileStream fs =
new FileStream(Server.MapPath(@"\Content\NPOITemplate.xls"), FileMode.Open, FileAccess.Read);
// Getting the complete workbook...
HSSFWorkbook templateWorkbook = new HSSFWorkbook(fs, true);
// Getting the worksheet by its name...
HSSFSheet sheet = templateWorkbook.GetSheet("Sheet1");
// Getting the row... 0 is the first row.
HSSFRow dataRow = sheet.GetRow(4);
// Setting the value 77 at row 5 column 1
dataRow.GetCell(0).SetCellValue(77);
// Forcing formula recalculation...
sheet.ForceFormulaRecalculation = true;
MemoryStream ms = new MemoryStream();
// Writing the workbook content to the FileStream...
templateWorkbook.Write(ms);
TempData["Message"] = "Excel report created successfully!";
// Sending the server processed data back to the user computer...
return File(ms.ToArray(), "application/vnd.ms-excel", "NPOINewFile.xls");
}
catch(Exception ex)

Simple Solution worked 100% for me
Put the class outside App_Code Folder

Actually awk
has a feature called 'Input Field Separator Variable' link. This is how to use it. It's not really an array, but it uses the internal $ variables. For splitting a simple string it is easier.
echo "12|23|11" | awk 'BEGIN {FS="|";} { print $1, $2, $3 }'
To perform *new tile_tree_apple
the constructor of tile_tree_apple
should be called, but in this place compiler knows nothing about tile_tree_apple
, so it can't use the constructor.
If you put
tile tile_tree::tick() {if (rand()%20==0) return *new tile_tree_apple;};
in separate cpp file which has the definition of class tile_tree_apple or includes the header file which has the definition everything will work fine.
You can use also the $args
variable (that's like position parameters):
$step = $args[0]
$iTunes = New-Object -ComObject iTunes.Application
if ($iTunes.playerstate -eq 1)
{
$iTunes.PlayerPosition = $iTunes.PlayerPosition + $step
}
Then it can be called like:
powershell.exe -file itunersforward.ps1 15
Try this:
mynewlist = [s for s in mylist if s.isdigit()]
From the docs:
str.isdigit()
Return true if all characters in the string are digits and there is at least one character, false otherwise.
For 8-bit strings, this method is locale-dependent.
As noted in the comments, isdigit()
returning True
does not necessarily indicate that the string can be parsed as an int via the int()
function, and it returning False
does not necessarily indicate that it cannot be. Nevertheless, the approach above should work in your case.
I had the same issue and tried all suggestions above, but didnt work out. I am posting my answer for furture readers. Before it was working fine but somehow it apeared again. I resolved this issue by removing some unnecessary plugnins and depencies from pom.xml
First of all, I changed default packaging type to jar (Spring Boot Initializer gives pom in packaging)
<packaging>jar</packaging>
I added unintentional some plugins:
<plugin>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<attachClasses>true</attachClasses>
<webXml>target/web.xml</webXml>
<webResources>
<resource>
<directory>src/main/webapp</directory>
<filtering>true</filtering>
</resource>
</webResources>
</configuration>
</plugin>
I hope my answer will help someone.
Here is one way to do it:
List<String> duplicates = lst.GroupBy(x => x)
.Where(g => g.Count() > 1)
.Select(g => g.Key)
.ToList();
The GroupBy
groups the elements that are the same together, and the Where
filters out those that only appear once, leaving you with only the duplicates.
I know that this topic is quite old, but this need is still alive. I read many documents, forum and script and build a new advanced one which supports compressed and uncompressed pdf :

For those who struggle at capturing Enter key on TextBox or other input control, if your Form has AcceptButton defined, you will not be able to use KeyDown event to capture Enter.
What you should do is to catch the Enter key at form level. Add this code to the form:
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if ((this.ActiveControl == myTextBox) && (keyData == Keys.Return))
{
//do something
return true;
}
else
{
return base.ProcessCmdKey(ref msg, keyData);
}
}
I know, very old thread but the proposed solution was not fully automatic when there are longer strings around.
I therefore created a small helper method which does it fully automatic. Just pass in a list of string array where each array represents a line and each element in the array, well an element of the line.
The method can be used like this:
var lines = new List<string[]>();
lines.Add(new[] { "What", "Before", "After"});
lines.Add(new[] { "Name:", name1, name2});
lines.Add(new[] { "City:", city1, city2});
lines.Add(new[] { "Zip:", zip1, zip2});
lines.Add(new[] { "Street:", street1, street2});
var output = ConsoleUtility.PadElementsInLines(lines, 3);
The helper method is as follows:
public static class ConsoleUtility
{
/// <summary>
/// Converts a List of string arrays to a string where each element in each line is correctly padded.
/// Make sure that each array contains the same amount of elements!
/// - Example without:
/// Title Name Street
/// Mr. Roman Sesamstreet
/// Mrs. Claudia Abbey Road
/// - Example with:
/// Title Name Street
/// Mr. Roman Sesamstreet
/// Mrs. Claudia Abbey Road
/// <param name="lines">List lines, where each line is an array of elements for that line.</param>
/// <param name="padding">Additional padding between each element (default = 1)</param>
/// </summary>
public static string PadElementsInLines(List<string[]> lines, int padding = 1)
{
// Calculate maximum numbers for each element accross all lines
var numElements = lines[0].Length;
var maxValues = new int[numElements];
for (int i = 0; i < numElements; i++)
{
maxValues[i] = lines.Max(x => x[i].Length) + padding;
}
var sb = new StringBuilder();
// Build the output
bool isFirst = true;
foreach (var line in lines)
{
if (!isFirst)
{
sb.AppendLine();
}
isFirst = false;
for (int i = 0; i < line.Length; i++)
{
var value = line[i];
// Append the value with padding of the maximum length of any value for this element
sb.Append(value.PadRight(maxValues[i]));
}
}
return sb.ToString();
}
}

Try to format your date with the Z
or z
timezone flags:
new SimpleDateFormat("MM/dd/yyyy KK:mm:ss a Z").format(dateObj);
The certificate that you already have is probably the server's certificate, or the certificate used to sign the server's certificate. You will need it so that your web service client can authenticate the server.
But if additionally you need to perform client authentication with SSL, then you need to get your own certificate, to authenticate your web service client. For this you need to create a certificate request; the process involves creating your own private key, and the corresponding public key, and attaching that public key along with some of your info (email, name, domain name, etc) to a file that's called the certificate request. Then you send that certificate request to the company that's already asked you for it, and they will create your certificate, by signing your public key with their private key, and they'll send you back an X509 file with your certificate, which you can now add to your keystore, and you'll be ready to connect to a web service using SSL requiring client authentication.
To generate your certificate request, use "keytool -certreq -alias -file -keypass -keystore ". Send the resulting file to the company that's going to sign it.
When you get back your certificate, run "keytool -importcert -alias -keypass -keystore ".
You may need to used -storepass in both cases if the keystore is protected (which is a good idea).
First, get the correct opencv version extension which you want to install. If you want to install 3.4.9.20 then run pip install opencv-python==3.4.5.20
.
You need to save your PHP script file in UTF-8 encoding, and leave the <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
in the HTML.
For text editor, I recommend Notepad++, because it can detect and display the actual encoding of the file (in the lower right corner of the editor), and you can convert it as well.
Don't forget to use var/let while declaring any variable.See below examples for JS compiler behaviour.
function func(){
return true;
}
isBool = func();
console.log(typeof (isBool)); // output - string
let isBool = func();
console.log(typeof (isBool)); // output - boolean
I suggest you to use provider
.
Provide is good when you want to configure it first before to use (against Service/Factory)
Something like:
.provider('Magazines', function() {
this.url = '/';
this.urlArray = '/';
this.organId = 'Default';
this.$get = function() {
var url = this.url;
var urlArray = this.urlArray;
var organId = this.organId;
return {
invoke: function() {
return ......
}
}
};
this.setUrl = function(url) {
this.url = url;
};
this.setUrlArray = function(urlArray) {
this.urlArray = urlArray;
};
this.setOrganId = function(organId) {
this.organId = organId;
};
});
.config(function(MagazinesProvider){
MagazinesProvider.setUrl('...');
MagazinesProvider.setUrlArray('...');
MagazinesProvider.setOrganId('...');
});
And now controller:
function MyCtrl($scope, Magazines) {
Magazines.invoke();
....
}
Along with sorted key store one another difference is with TreeMap, developer can give (String.CASE_INSENSITIVE_ORDER) with String keys, so then the comparator ignores case of key while performing comparison of keys on map access. This is not possible to give such option with HashMap - it is always case sensitive comparisons in HashMap.

In the original post author concatenated strings. Every sting operation will result in string recreation in .Net. String is effectively a reference type. As a result, the function provided will be visibly slow. Don't do that. Use array of chars instead, write there directly and then convert result to string. In my case of processing 500 kb of text difference is almost 5 minutes.
Session is used mainly for storing user specific data [ session specific data ]. In the case of session you can use the value for the whole session until the session expires or the user abandons the session. Viewstate is the type of data that has scope only in the page in which it is used. You canot have viewstate values accesible to other pages unless you transfer those values to the desired page. Also in the case of viewstate all the server side control datas are transferred to the server as key value pair in __Viewstate and transferred back and rendered to the appropriate control in client when postback occurs.
Try this:
if( $this->container->get('security.context')->isGranted('IS_AUTHENTICATED_FULLY') ){
// authenticated (NON anonymous)
}
Further information:
"Anonymous users are technically authenticated, meaning that the isAuthenticated() method of an anonymous user object will return true. To check if your user is actually authenticated, check for the IS_AUTHENTICATED_FULLY role."
Since this must have an input element as a parent, you could just use
<input type="text" ng-model="foo" ng-change="myOnChangeFunction()">
Alternatively, you could use the ngModelController
and add a function to $formatters
, which executes functions on input change. See http://docs.angularjs.org/api/ng.directive:ngModel.NgModelController
.directive("myDirective", function() {
return {
restrict: 'A',
require: 'ngModel',
link: function(scope, element, attr, ngModel) {
ngModel.$formatters.push(function(value) {
// Do stuff here, and return the formatted value.
});
};
};
Overload a function:
unsigned int rotate_right(unsigned int x)
{
return (x>>1 | (x&1?0x80000000:0))
}
unsigned short rotate_right(unsigned short x) { /* etc. */ }
The email in the profile can be obtained using extended permission but I Guess it's not possible to get the email used to login fb. In my app i wanted to display mulitple fb accounts of a user in a list, i wanted to show the login emails of fb accounts as a unique identifier of the respective accounts but i couldn't get it off from fb, all i got was the primary email in the user profile but in my case my login email and my primary email are different.

Maps never take into consideration the whole map. My guess is:- 1. According to your location, they load a place and the landmarks on that place. 2. When you search the destination, thats when they load the other part of the map and make a graph out of two places and then apply the shortest path algorithms.
Also, there is an important technique Dynamic programming which i suspect is used in the calculation of shortest paths. You can refer to that as well.
Sorry for only commenting in the first place, but i'm posting almost every day a similar comment since many people think that it would be smart to encapsulate ADO.NET functionality into a DB-Class(me too 10 years ago). Mostly they decide to use static/shared objects since it seems to be faster than to create a new object for any action.
That is neither a good idea in terms of peformance nor in terms of fail-safety.
There's a good reason why ADO.NET internally manages the underlying Connections to the DBMS in the ADO-NET Connection-Pool:
In practice, most applications use only one or a few different configurations for connections. This means that during application execution, many identical connections will be repeatedly opened and closed. To minimize the cost of opening connections, ADO.NET uses an optimization technique called connection pooling.
Connection pooling reduces the number of times that new connections must be opened. The pooler maintains ownership of the physical connection. It manages connections by keeping alive a set of active connections for each given connection configuration. Whenever a user calls Open on a connection, the pooler looks for an available connection in the pool. If a pooled connection is available, it returns it to the caller instead of opening a new connection. When the application calls Close on the connection, the pooler returns it to the pooled set of active connections instead of closing it. Once the connection is returned to the pool, it is ready to be reused on the next Open call.
So obviously there's no reason to avoid creating,opening or closing connections since actually they aren't created,opened and closed at all. This is "only" a flag for the connection pool to know when a connection can be reused or not. But it's a very important flag, because if a connection is "in use"(the connection pool assumes), a new physical connection must be openend to the DBMS what is very expensive.
So you're gaining no performance improvement but the opposite. If the maximum pool size specified (100 is the default) is reached, you would even get exceptions(too many open connections ...). So this will not only impact the performance tremendously but also be a source for nasty errors and (without using Transactions) a data-dumping-area.
If you're even using static connections you're creating a lock for every thread trying to access this object. ASP.NET is a multithreading environment by nature. So theres a great chance for these locks which causes performance issues at best. Actually sooner or later you'll get many different exceptions(like your ExecuteReader requires an open and available Connection).
Conclusion:
using-statement
to dispose and close(in case of Connections) implicitelyThat's true not only for Connections(although most noticable). Every object implementing IDisposable
should be disposed(simplest by using-statement
), all the more in the System.Data.SqlClient
namespace.
All the above speaks against a custom DB-Class which encapsulates and reuse all objects. That's the reason why i commented to trash it. That's only a problem source.
Edit: Here's a possible implementation of your retrievePromotion
-method:
public Promotion retrievePromotion(int promotionID)
{
Promotion promo = null;
var connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["MainConnStr"].ConnectionString;
using (SqlConnection connection = new SqlConnection(connectionString))
{
var queryString = "SELECT PromotionID, PromotionTitle, PromotionURL FROM Promotion WHERE PromotionID=@PromotionID";
using (var da = new SqlDataAdapter(queryString, connection))
{
// you could also use a SqlDataReader instead
// note that a DataTable does not need to be disposed since it does not implement IDisposable
var tblPromotion = new DataTable();
// avoid SQL-Injection
da.SelectCommand.Parameters.Add("@PromotionID", SqlDbType.Int);
da.SelectCommand.Parameters["@PromotionID"].Value = promotionID;
try
{
connection.Open(); // not necessarily needed in this case because DataAdapter.Fill does it otherwise
da.Fill(tblPromotion);
if (tblPromotion.Rows.Count != 0)
{
var promoRow = tblPromotion.Rows[0];
promo = new Promotion()
{
promotionID = promotionID,
promotionTitle = promoRow.Field<String>("PromotionTitle"),
promotionUrl = promoRow.Field<String>("PromotionURL")
};
}
}
catch (Exception ex)
{
// log this exception or throw it up the StackTrace
// we do not need a finally-block to close the connection since it will be closed implicitely in an using-statement
throw;
}
}
}
return promo;
}
This is known as a Zip operation and will be supported in .NET 4.
With that, you would be able to write something like:
var numbers = new [] { 1, 2, 3, 4 };
var words = new [] { "one", "two", "three", "four" };
var numbersAndWords = numbers.Zip(words, (n, w) => new { Number = n, Word = w });
foreach(var nw in numbersAndWords)
{
Console.WriteLine(nw.Number + nw.Word);
}
As an alternative to the anonymous type with the named fields, you can also save on braces by using a Tuple and its static Tuple.Create helper:
foreach (var nw in numbers.Zip(words, Tuple.Create))
{
Console.WriteLine(nw.Item1 + nw.Item2);
}
I know I'm uprising a very old topic, but after a couple of hours struggling with this very problem and not finding a solution anywhere else, I think this is a good place to put an answer.
We have some Build Servers WindowsXP based and found this very problem: svn command line client is not caching auth credentials.
We finally found out that we are using Cygwin's svn client! not a "native" Windows. So... this client stores all the auth credentials in /home/<user>/.subversion/auth
This /home directory in Cygwin, in our installation is in c:\cygwin\home. AND: the problem was that the Windows user that is running svn did never ever "logged in" in Cygwin, and so there was no /home/<user> directory.
A simple "bash -ls" from a Windows command terminal created the directory, and after the first access to our SVN server with interactive prompting for access credentials, alás, they got cached.
So if you are using Cygwin's svn client, be sure to have a "home" directory created for the local Windows user.
Things are going better, right now you can use SVG files.

In most cases, it is enough just to hide the element, for example in this way:
export default class ErrorBoxComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
isHidden: false
}
}
dismiss() {
this.setState({
isHidden: true
})
}
render() {
if (!this.props.error) {
return null;
}
return (
<div data-alert className={ "alert-box error-box " + (this.state.isHidden ? 'DISPLAY-NONE-CLASS' : '') }>
{ this.props.error }
<a href="#" className="close" onClick={ this.dismiss.bind(this) }>×</a>
</div>
);
}
}
Or you may render/rerender/not render via parent component like this
export default class ParentComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
isErrorShown: true
}
}
dismiss() {
this.setState({
isErrorShown: false
})
}
showError() {
if (this.state.isErrorShown) {
return <ErrorBox
error={ this.state.error }
dismiss={ this.dismiss.bind(this) }
/>
}
return null;
}
render() {
return (
<div>
{ this.showError() }
</div>
);
}
}
export default class ErrorBoxComponent extends React.Component {
dismiss() {
this.props.dismiss();
}
render() {
if (!this.props.error) {
return null;
}
return (
<div data-alert className="alert-box error-box">
{ this.props.error }
<a href="#" className="close" onClick={ this.dismiss.bind(this) }>×</a>
</div>
);
}
}
Finally, there is a way to remove html node, but i really dont know is it a good idea. Maybe someone who knows React from internal will say something about this.
export default class ErrorBoxComponent extends React.Component {
dismiss() {
this.el.remove();
}
render() {
if (!this.props.error) {
return null;
}
return (
<div data-alert className="alert-box error-box" ref={ (el) => { this.el = el} }>
{ this.props.error }
<a href="#" className="close" onClick={ this.dismiss.bind(this) }>×</a>
</div>
);
}
}

If you have Python 2.6 or newer, use format
:
'{0:.3g}'.format(num)
For Python 2.5 or older:
'%.3g'%(num)
Explanation:
{0}
tells format
to print the first argument -- in this case, num
.
Everything after the colon (:) specifies the format_spec
.
.3
sets the precision to 3.
g
removes insignificant zeros. See
http://en.wikipedia.org/wiki/Printf#fprintf
For example:
tests=[(1.00, '1'),
(1.2, '1.2'),
(1.23, '1.23'),
(1.234, '1.23'),
(1.2345, '1.23')]
for num, answer in tests:
result = '{0:.3g}'.format(num)
if result != answer:
print('Error: {0} --> {1} != {2}'.format(num, result, answer))
exit()
else:
print('{0} --> {1}'.format(num,result))
yields
1.0 --> 1
1.2 --> 1.2
1.23 --> 1.23
1.234 --> 1.23
1.2345 --> 1.23
Using Python 3.6 or newer, you could use f-strings
:
In [40]: num = 1.234; f'{num:.3g}'
Out[40]: '1.23'
Just use HTML5 :)

I think the exception safety part of mr mpark's answer is still a valid concern. when creating a shared_ptr like this: shared_ptr< T >(new T), the new T may succeed, while the shared_ptr's allocation of control block may fail. in this scenario, the newly allocated T will leak, since the shared_ptr has no way of knowing that it was created in-place and it is safe to delete it. or am I missing something? I don't think the stricter rules on function parameter evaluation help in any way here...
In jQuery, when you handle the click event, return false to stop the link from responding the usual way prevent the default action, which is to visit the href
attribute, from taking place (per PoweRoy's comment and Erik's answer):
$('a.someclass').click(function(e)
{
// Special stuff to do when this link is clicked...
// Cancel the default action
e.preventDefault();
});
I think this is very nice and short
<img src="imagenotfound.gif" alt="Image not found" onerror="this.src='imagefound.gif';" />
But, be careful. The user's browser will be stuck in an endless loop if the onerror image itself generates an error.
EDIT
To avoid endless loop, remove the onerror
from it at once.
<img src="imagenotfound.gif" alt="Image not found" onerror="this.onerror=null;this.src='imagefound.gif';" />
By calling this.onerror=null
it will remove the onerror then try to get the alternate image.
NEW I would like to add a jQuery way, if this can help anyone.
<script>
$(document).ready(function()
{
$(".backup_picture").on("error", function(){
$(this).attr('src', './images/nopicture.png');
});
});
</script>
<img class='backup_picture' src='./images/nonexistent_image_file.png' />
You simply need to add class='backup_picture' to any img tag that you want a backup picture to load if it tries to show a bad image.

The problem is that the function returns UTF-8 (it can check using mb_detect_encoding), but do not convert, and these characters takes as UTF-8. ?herefore, it's necessary to do the reverse-convert to initial encoding (Windows-1251 or CP1251) using iconv. But since by the fgetcsv returns an array, I suggest to write a custom function: [Sorry for my english]
function customfgetcsv(&$handle, $length, $separator = ';'){
if (($buffer = fgets($handle, $length)) !== false) {
return explode($separator, iconv("CP1251", "UTF-8", $buffer));
}
return false;
}
For curves with not too much noise, I recommend the following small code snippet:
from numpy import *
# example data with some peaks:
x = linspace(0,4,1e3)
data = .2*sin(10*x)+ exp(-abs(2-x)**2)
# that's the line, you need:
a = diff(sign(diff(data))).nonzero()[0] + 1 # local min+max
b = (diff(sign(diff(data))) > 0).nonzero()[0] + 1 # local min
c = (diff(sign(diff(data))) < 0).nonzero()[0] + 1 # local max
# graphical output...
from pylab import *
plot(x,data)
plot(x[b], data[b], "o", label="min")
plot(x[c], data[c], "o", label="max")
legend()
show()
The +1
is important, because diff
reduces the original index number.
GETDATE()
returns current date and time.
If last year starts in midnight of current day last year (like in original example) you should use something like:
DECLARE @start datetime
SET @start = dbo.getdatewithouttime(DATEADD(year, -1, GETDATE())) -- cut time (hours, minutes, ect.) -- getdatewithouttime() function doesn't exist in MS SQL -- you have to write one
SELECT column1, column2, ..., columnN FROM table WHERE date >= @start
Dividing two integers will result in an integer (whole number) result.
You need to cast one number as a float, or add a decimal to one of the numbers, like a/350.0.
Also if you're using 3rd party libraries make sure you have the correct 32/64 bit binaries

Update: Don't use this answer since this is very dumb code that I found while I learn. Just use plain getter and setter, it's much better.
I usually using that variable name as function name, and add optional parameter to that function so when that optional parameter is filled by caller, then set it to the property and return $this object (chaining) and then when that optional parameter not specified by caller, i just return the property to the caller.
My example:
class Model
{
private $propOne;
private $propTwo;
public function propOne($propVal = '')
{
if ($propVal === '') {
return $this->propOne;
} else {
$this->propOne = $propVal;
return $this;
}
}
public function propTwo($propVal = '')
{
if ($propVal === '') {
return $this->propTwo;
} else {
$this->propTwo = $propVal;
return $this;
}
}
}
This example uses jquery-cookie
Check if the cookie exists and has not expired - if either of those fails, then show the popup and set the cookie (Semi pseudo code):
if($.cookie('popup') != 'seen'){
$.cookie('popup', 'seen', { expires: 365, path: '/' }); // Set it to last a year, for example.
$j("#popup").delay(2000).fadeIn();
$j('#popup-close').click(function(e) // You are clicking the close button
{
$j('#popup').fadeOut(); // Now the pop up is hiden.
});
$j('#popup').click(function(e)
{
$j('#popup').fadeOut();
});
};
You can create a new model to Deserialize your Json CustomerJson
:
public class CustomerJson
{
[JsonProperty("customer")]
public Customer Customer { get; set; }
}
public class Customer
{
[JsonProperty("first_name")]
public string Firstname { get; set; }
[JsonProperty("last_name")]
public string Lastname { get; set; }
...
}
And you can deserialize your json easily :
JsonConvert.DeserializeObject<List<CustomerJson>>(json);
Hope it helps !

I got a MD5 hash with different results for both key and certificate.
This says it all. You have a mismatch between your key and certificate.
The modulus should match. Make sure you have correct key.
I had to add "Current" using .NET 4.5:
HttpContext.Current.Server.ScriptTimeout = 300;
Your C++ is showing.
There is no delete
in java, and all objects are created on the heap. The JVM has a garbage collector that relies on reference counts.
Once there are no more references to an object, it becomes available for collection by the garbage collector.
myObject = null
may not do it; for example:
Foo myObject = new Foo(); // 1 reference
Foo myOtherObject = myObject; // 2 references
myObject = null; // 1 reference
All this does is set the reference myObject
to null, it does not affect the object myObject
once pointed to except to simply decrement the reference count by 1. Since myOtherObject
still refers to that object, it is not yet available to be collected.
Whenever a TypeInitializationException
is thrown, check all initialization logic of the type you are referring to for the first time in the statement where the exception is thrown - in your case: Logger
.
Initialization logic includes: the type's static constructor (which - if I didn't miss it - you do not have for Logger
) and field initialization.
Field initialization is pretty much "uncritical" in Logger
except for the following lines:
private static string s_bstCommonAppData = Path.Combine(s_commonAppData, "XXXX");
private static string s_bstUserDataDir = Path.Combine(s_bstCommonAppData, "UserData");
private static string s_commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);
s_commonAppData
is null
at the point where Path.Combine(s_commonAppData, "XXXX");
is called. As far as I'm concerned, these initializations happen in the exact order you wrote them - so put s_commonAppData
up by at least two lines ;)
Remember to put not only the tag but also the repository in which that tag is, this way:
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
elixir 1.7-centos7_3 e15e6bf57262 20 hours ago 925MB
You should reference it this way:
elixir:1.7-centos7_3
Right click on "Command prompt" or "PowerShell", in menu click "Run as Administrator" (on Windows XP you can just run it as usual).
As Rick Vanover mentions in See what process is using a TCP port in Windows Server 2008
The following command will show what network traffic is in use at the port level:
Netstat -a -n -o
or
Netstat -a -n -o >%USERPROFILE%\ports.txt
(to open the port and process list in a text editor, where you can search for information you want)
Then,
with the PIDs listed in the netstat output, you can follow up with the Windows Task Manager (taskmgr.exe) or run a script with a specific PID that is using a port from the previous step. You can then use the "tasklist" command with the specific PID that corresponds to a port in question.
Example:
tasklist /svc /FI "PID eq 1348"
Use the extractall
method, if you're using Python 2.6+
zip = ZipFile('file.zip')
zip.extractall()
You can use:
$answer.replace(' ' , '')
or
$answer -replace " ", ""
if you want to remove all whitespace you can use:
$answer -replace "\s", ""
Try MyEnum.values()[x]
where x
must be 0
or 1
, i.e. a valid ordinal for that enum.
Note that in Java enums actually are classes (and enum values thus are objects) and thus you can't cast an int
or even Integer
to an enum.
Since your question is more generic so try to implement it with XML Parsers available in Java .If you need it in specific to parsers, update your code here what you have tried yet
<?xml version="1.0" encoding="UTF-8"?>
<ep>
<source type="xml">TEST</source>
<source type="text"></source>
</ep>
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse("uri to xmlfile");
XPathFactory xPathfactory = XPathFactory.newInstance();
XPath xpath = xPathfactory.newXPath();
XPathExpression expr = xpath.compile("//ep/source[@type]");
NodeList nl = (NodeList) expr.evaluate(doc, XPathConstants.NODESET);
for (int i = 0; i < nl.getLength(); i++)
{
Node currentItem = nl.item(i);
String key = currentItem.getAttributes().getNamedItem("type").getNodeValue();
System.out.println(key);
}
Installig Eclispe ADT from market place solved this problem for me.
If you're still getting this error message:
TS7016: Could not find a declaration file for module './myjsfile'
Then you might need to add the following to tsconfig.json
{
"compilerOptions": {
...
"allowJs": true,
"checkJs": false,
...
}
}
This prevents typescript from trying to apply module types to the imported javascript.
if [ ! -d directory ]; then

If anyone wants to use purely Java configuration instead of xml
configuration of hibernate, use this:
You can configure Hibernate without using persistence.xml at all in Spring like like this:
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean()
{
Map<String, Object> properties = new Hashtable<>();
properties.put("javax.persistence.schema-generation.database.action",
"none");
HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
adapter.setDatabasePlatform("org.hibernate.dialect.MySQL5InnoDBDialect"); //you can change this if you have a different DB
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(adapter);
factory.setDataSource(this.springJpaDataSource());
factory.setPackagesToScan("package name");
factory.setSharedCacheMode(SharedCacheMode.ENABLE_SELECTIVE);
factory.setValidationMode(ValidationMode.NONE);
factory.setJpaPropertyMap(properties);
return factory;
}
Since you are not using persistence.xml, you should create a bean that returns DataSource which you specify in the above method that sets the data source:
@Bean
public DataSource springJpaDataSource()
{
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setUrl("jdbc:mysql://localhost/SpringJpa");
dataSource.setUsername("tomcatUser");
dataSource.setPassword("password1234");
return dataSource;
}
Then you use @EnableTransactionManagement
annotation over this configuration file. Now when you put that annotation, you have to create one last bean:
@Bean
public PlatformTransactionManager jpaTransactionManager()
{
return new JpaTransactionManager(
this.entityManagerFactoryBean().getObject());
}
Now, don't forget to use @Transactional
Annotation over those method that deal with DB.
Lastly, don't forget to inject EntityManager
in your repository (This repository class should have @Repository
annotation over it).
The closest equivalent to Java's toString
is to implement __str__
for your class. Put this in your class definition:
def __str__(self):
return "foo"
You may also want to implement __repr__
to aid in debugging.
See here for more information:
These are called auto properties.
http://msdn.microsoft.com/en-us/library/bb384054.aspx
Functionally (and in terms of the compiled IL), they are the same as properties with backing fields.
You can write your own function that does the same thing as strcat()
but that doesn't change anything:
#define MAX_STRING_LENGTH 1000
char *strcat_const(const char *str1,const char *str2){
static char buffer[MAX_STRING_LENGTH];
strncpy(buffer,str1,MAX_STRING_LENGTH);
if(strlen(str1) < MAX_STRING_LENGTH){
strncat(buffer,str2,MAX_STRING_LENGTH - strlen(buffer));
}
buffer[MAX_STRING_LENGTH - 1] = '\0';
return buffer;
}
int main(int argc,char *argv[]){
printf("%s",strcat_const("Hello ","world")); //Prints "Hello world"
return 0;
}
If both strings together are more than 1000 characters long, it will cut the string at 1000 characters. You can change the value of MAX_STRING_LENGTH
to suit your needs.
There is a segmentation fault problem which was introduced in 0.1.39. You may check my repository that fixed this one in meanwhile: https://github.com/vdudouyt/mhddfs-nosegfault
You can use {}
arround your variable, to separate it from what's after:
echo "{$test}y"
As reference, you can take a look to the Variable parsing - Complex (curly) syntax section of the PHP manual.
I suppose the language is C, or C++...
strtok, IIRC, replace separators with \0. That's what it cannot use a const string. To workaround that "quickly", if the string isn't huge, you can just strdup() it. Which is wise if you need to keep the string unaltered (what the const suggest...).
On the other hand, you might want to use another tokenizer, perhaps hand rolled, less violent on the given argument.
The most common application here is closing on clicking the document but not when it came from within that element, for this you want to stop the bubbling, like this:
$(".menuWrapper").click(function(e) {
e.stopPropagation(); //stops click event from reaching document
});
$(document).click(function() {
$(".menuWrapper").hide(); //click came from somewhere else
});
All were doing here is preventing the click from bubbling up (via event.stopPrpagation()
) when it came from within a .menuWrapper
element. If this didn't happen, the click came from somewhere else, and will by default make it's way up to document
, if it gets there, we hide those .menuWrapper
elements.
One reason to use object
over iframe
is that object re-sizes the embedded content to fit the object dimensions. most notable on safari in iPhone 4s where screen width is 320px
and the html from the embedded URL may set dimensions greater.
You can get the example of css implemented html to pdf conversion using jspdf on following link: JSFiddle Link
This is sample code for the jspdf html to pdf download.

var pdf = new jsPDF('p','pt','a4');
pdf.addHTML(document.body,function() {
pdf.save('web.pdf');
});
})

})
It's the quickest way I've found without doing any subclasses:
UIView *spacerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10., 10.)];
[textField setLeftViewMode:UITextFieldViewModeAlways];
[textField setLeftView:spacerView];
In Swift:
let spacerView = UIView(frame:CGRect(x:0, y:0, width:10, height:10))
textField.leftViewMode = UITextFieldViewMode.Always
textField.leftView = spacerView
If you already have the string, you can use this function:
bool isNumber( const string& s )
{
bool hitDecimal=0;
for( char c : s )
{
if( c=='.' && !hitDecimal ) // 2 '.' in string mean invalid
hitDecimal=1; // first hit here, we forgive and skip
else if( !isdigit( c ) )
return 0 ; // not ., not
}
return 1 ;
}
If you are facing this issue after changing password in phpmyadmin,
paste the old password (passwd before change) in xampp\phpMyAdmin\config.inc.php
:
$cfg['Servers'][$i]['password'] = '**old password here**';
Hope, it would work :)
I would use DATEFROMPARTS function. It is quite easy and you don't need casting. As an example this query :
Select DATEFROMPARTS(YEAR(GETDATE()), MONTH(GETDATE()), DAY(GETDATE())) as myNewDate
will return
2021-01-21
The good part you can also create you own date, for example you want first day of a month as a date, than you can just use like below:
Select DATEFROMPARTS(YEAR(GETDATE()), MONTH(GETDATE()), 1) as myNewDate
The result will be:
2021-01-01
try this:
import sys
sys.argv = ['arg1', 'arg2']
execfile('abc.py')
Note that when abc.py
finishes, control will be returned to the calling program. Note too that abc.py
can call quit()
if indeed finished.
Java enums are not like C or C++ enums, which are really just labels for integers.
Java enums are implemented more like classes - and they can even have multiple attributes.
public enum Ids {
OPEN(100), CLOSE(200);
private final int id;
Ids(int id) { this.id = id; }
public int getValue() { return id; }
}
The big difference is that they are type-safe which means you don't have to worry about assigning a COLOR enum to a SIZE variable.
See http://docs.oracle.com/javase/tutorial/java/javaOO/enum.html for more.
For .net 2.0 this works. It DOES compile both in the same project if you create sub directories of in app code with the related language code. As of yet, I am looking for whether this should work in 3.5 or not though.
You can use double quotes instead of single quotes:
theAnchorText = "I'm home";
Alternatively, escape the apostrophe:
theAnchorText = 'I\'m home';
The backslash tells JavaScript (this has nothing to do with jQuery, by the way) that the next character should be interpreted as "special". In this case, an apostrophe after a backslash means to use a literal apostrophe but not to end the string.
There are also other characters you can put after a backslash to indicate other special characters. For example, you can use \n
for a new line, or \t
for a tab.
Generally...
Hibernate is used for handling database operations. There is a rich set of database utility functionality, which reduces your number of lines of code. Especially you have to read @Annotation of hibernate. It is an ORM framework and persistence layer.
Spring provides a rich set of the Injection based working mechanism. Currently, Spring is well-known. You have to also read about Spring AOP. There is a bridge between Struts and Hibernate. Mainly Spring provides this kind of utility.
Struts2 provides action based programming. There are a rich set of Struts tags. Struts prove action based programming so you have to maintain all the relevant control of your view.
In Addition, Tapestry is a different framework for Java. In which you have to handle only .tml
(template file). You have to create two main files for any class. One is JAVA class and another one is its template. Both names are same. Tapestry automatically calls related classes.
I wanted a way to simply and automatically report errors (since users often don't) from our applications. The easiest solution I could come up with was a public URL - a web page which could take input and store it to a database - that is sent data upon an application error. (The database could then be checked by a dev or a script to know if there are new errors.)
I wrote the web page in PHP and created a mysql database, user, and table to store the data. I decided on four user variables, an id, and a timestamp. The possible variables (either included in the URL or as POST data) are:
app
(application name)msg
(message - e.g. Exception occurred ...)dev
(developer - e.g. Pat)src
(source - this would come from a variable pertaining to the machine on which the app was running, e.g. Environment.MachineName
or some such)log
(a log file or verbose message)(All of the variables are optional, but nothing is reported if none of them are set - so if you just visit the website URL nothing is sent to the db.)
To send the data to the URL, I used NLog's WebService
target. (Note, I had a few problems with this target at first. It wasn't until I looked at the source that I figured out that my url
could not end with a /
.)
All in all, it's not a bad system for keeping tabs on external apps. (Of course, the polite thing to do is to inform your users that you will be reporting possibly sensitive data and to give them a way to opt in/out.)
(The db user has only INSERT
privileges on this one table in its own database.)
CREATE TABLE `reports` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`ts` timestamp NULL DEFAULT CURRENT_TIMESTAMP,

Note: there may be some issues with the size of the log file, but I haven't figured out a simple way to truncate it (e.g. a la *nix's tail
command).
super late entry but GAAP is a good rule of thumb..
If your application needs to handle money values up to a trillion then this should work: 13,2 If you need to comply with GAAP (Generally Accepted Accounting Principles) then use: 13,4
Usually you should sum your money values at 13,4 before rounding of the output to 13,2.
Assuming your page is available under "http://example.com"
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Firefox()
driver.get("http://example.com")
Select element by id:
inputElement = driver.find_element_by_id("a1")
inputElement.send_keys('1')
Now you can simulate hitting ENTER:
inputElement.send_keys(Keys.ENTER)
or if it is a form you can submit:
inputElement.submit()
I would suggest static class with static readonly. Please find the code snippet below:
public static class CachedKeysManager
{
public static readonly string DistributorList = "distributorList";
}
If you mind to use LINQ Expression;
public static Dictionary<string, object> ConvertFromObjectToDictionary(object arg)
{
return arg.GetType().GetProperties().ToDictionary(property => property.Name, property => property.GetValue(arg));
}
I tried above align attribute in HTML5. It is not supported. Also I tried flex-align and vertival-align with style attributes. Still not able to place TABLE in center of screen. The following style place table in center horizontally.
style="margin:auto;"
I'd do this:
add the dependency as you like in your pom:
<dependency>
<groupId>com.stackoverflow...</groupId>
<artifactId>artifactId...</artifactId>
<version>1.0</version>
</dependency>
run mvn install
it will try to download the jar and fail. On the process, it
will give you the complete command of installing the jar with the error message. Copy that command and run it! easy huh?!
SELECT STR_TO_DATE(dateString, '%d/%m/%y') FROM yourTable...
The Ookii Dialogs for WPF library has a class that provides an implementation of a folder browser dialog for WPF.
There's also a version that works with Windows Forms.
Use the method Int.Parse()
instead. It will work.
Since mobile doesn't give hover feedback, I want, as a user, to see instant feedback when a link is tapped. I noticed that -webkit-tap-highlight-color
is the fastest to respond (subjective).
Add the following to your body and your links will have a tap effect.
body {
-webkit-tap-highlight-color: #ccc;
}
Have you tried: http://flori.github.com/json/?
Failing that, you could just parse it out? If it's only arrays you're interested in, something to split the above out will be quite simple.
As per your question vertical listing have a scrollbar effect.
