string name;
char *c_string;
getline(cin, name);
c_string = new char[name.length()];
for (int index = 0; index < name.length(); index++){
c_string[index] = name[index];
}
c_string[name.length()] = '\0';//add the null terminator at the end of
// the char array
I know this is not the predefined method but thought it may be useful to someone nevertheless.

Convert CString to string (VC6)
I have tested this and it works fine.
std::string Utils::CString2String(const CString& cString)
{
std::string strStd;
for (int i = 0; i < cString.GetLength(); ++i)
{
if (cString[i] <= 0x7f)
strStd.append(1, static_cast<char>(cString[i]));
else
strStd.append(1, '?');
}
return strStd;
}
Here is an example of how to use strtok borrowed from MSDN.
And the relevant bits, you need to call it multiple times. The token
char* is the part you would stuff into an array (you can figure that part out).
char string[] = "A string\tof ,,tokens\nand some more tokens";
char seps[] = " ,\t\n";
char *token;
int main( void )
{
printf( "Tokens:\n" );
/* Establish string and get the first token: */
token = strtok( string, seps );
while( token != NULL )
{
/* While there are tokens in "string" */
printf( " %s\n", token );
/* Get next token: */
token = strtok( NULL, seps );
}
}
To "remove" the 1st character point to the second character:
char mystr[] = "Nmy stringP";
char *p = mystr;
p++; /* 'N' is not in `p` */
To remove the last character replace it with a '\0'
.
p[strlen(p)-1] = 0; /* 'P' is not in `p` (and it isn't in `mystr` either) */
Pretty concise solution with plain Java 8 using java.util.stream
:
public static <T> ArrayList<T> toArrayList(final Iterator<T> iterator) {
return StreamSupport
.stream(
Spliterators
.spliteratorUnknownSize(iterator, Spliterator.ORDERED), false)
.collect(
Collectors.toCollection(ArrayList::new)
);
}
I just wanted to add the fix I found for this issue. I'm not sure why this worked. I had the correct version of jstl (1.2) and also the correct version of servlet-api (2.5)
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
I also had the correct address in my page as suggested in this thread, which is
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
What fixed this issue for me was removing the scope tag from my xml file in the pom for my jstl 1.2 dependency. Again not sure why that fixed it but just in case someone is doing the spring with JPA and Hibernate tutorial on pluralsight and has their pom setup this way, try removing the scope tag and see if that fixes it. Like I said it worked for me.
So how can I question a variable that is a NoneType?
Use is
operator, like this
if variable is None:
Why this works?
Since None
is the sole singleton object of NoneType
in Python, we can use is
operator to check if a variable has None
in it or not.
Quoting from is
docs,
The operators
is
andis not
test for object identity:x is y
is true if and only ifx
andy
are the same object.x is not y
yields the inverse truth value.
Since there can be only one instance of None
, is
would be the preferred way to check None
.
Hear it from the horse's mouth
Quoting Python's Coding Style Guidelines - PEP-008 (jointly defined by Guido himself),
Comparisons to singletons like
None
should always be done withis
oris not
, never the equality operators.
Here you go:
Just change the line1 style as per below:
line1: {
backgroundColor: '#FDD7E4',
width:'100%',
alignSelf:'center'
}
instead of csv, trying outputting html with an XLS extension and "application/excel" mime-type. I know this will work in Windows, but can't speak for MacOS
Another solution is to fix the socket location in the php.ini configuration file like this:
pdo_mysql.default_socket=/tmp/mysql.sock
Of course, the symlink works too, so its a matter of preference which one you change.
To expand on user8266077's answer, I found that I still needed to supply OPTIONS response for preflight requests in .NET Core 2.1-preview for my use case:
// https://stackoverflow.com/a/45844400
public class CorsMiddleware
{
private readonly RequestDelegate _next;
public CorsMiddleware(RequestDelegate next)
{
_next = next;
}
public async Task Invoke(HttpContext context)
{
context.Response.Headers.Add("Access-Control-Allow-Origin", "*");
context.Response.Headers.Add("Access-Control-Allow-Credentials", "true");
// Added "Accept-Encoding" to this list
context.Response.Headers.Add("Access-Control-Allow-Headers", "Content-Type, X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Accept-Encoding, Content-Length, Content-MD5, Date, X-Api-Version, X-File-Name");
context.Response.Headers.Add("Access-Control-Allow-Methods", "POST,GET,PUT,PATCH,DELETE,OPTIONS");
// New Code Starts here
if (context.Request.Method == "OPTIONS")
{
context.Response.StatusCode = (int)HttpStatusCode.OK;
await context.Response.WriteAsync(string.Empty);
}
// New Code Ends here
await _next(context);
}
}
and then enabled the middleware like so in Startup.cs
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.UseMiddleware(typeof(CorsMiddleware));
// ... other middleware inclusion such as ErrorHandling, Caching, etc
app.UseMvc();
}
This can be done using list comprehensions as defined in PEP 202
[w.strip() for w in ['this\n', 'is\n', 'a\n', 'list\n', 'of\n', 'words\n']]
My Jenkins pipeline step shown below failed with the same error.
steps {
echo 'Building ...'
sh 'sh ./Tools/build.sh'
}
In my "build.sh" script file "docker run" command output this error when it was executed by Jenkins job. However it was working OK when the script ran in the shell terminal.The error happened because of -t option passed to docker run command that as I know tries to allocate terminal and fails if there is no terminal to allocate.
In my case I have changed the script to pass -t option only if a terminal could be detected. Here is the code after changes :
DOCKER_RUN_OPTIONS="-i --rm"
# Only allocate tty if we detect one
if [ -t 0 ] && [ -t 1 ]; then
DOCKER_RUN_OPTIONS="$DOCKER_RUN_OPTIONS -t"
fi
docker run $DOCKER_RUN_OPTIONS --name my-container-name my-image-tag
update table_name set field1 = field1 + 1;
Use the below code in the onCreate() method of your activity:
try {
PackageInfo info = getPackageManager().getPackageInfo(
"your application package name",
PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
}
}
catch (NameNotFoundException e) {
}
catch (NoSuchAlgorithmException e) {
}
Run this code. This will generate the hash key. Copy this KeyHash in the Facebook application setting, and save changes. Then log into your application. This will work perfectly in the future too.
Given the html below:
<button class="btn-without-border"> Submit </button>
In the css style do the following:
.btn-without-border:focus {
border: none;
outline: none;
}
This code will remove button border and will disable button border focus when the button is clicked.
You'll need to use a static
readonly
list instead. And if you want the list to be immutable then you might want to consider using ReadOnlyCollection<T>
rather than List<T>
.
private static readonly ReadOnlyCollection<string> _metrics =
new ReadOnlyCollection<string>(new[]
{
SourceFile.LOC,
SourceFile.MCCABE,
SourceFile.NOM,
SourceFile.NOA,
SourceFile.FANOUT,
SourceFile.FANIN,
SourceFile.NOPAR,
SourceFile.NDC,
SourceFile.CALLS
});
public static ReadOnlyCollection<string> Metrics
{
get { return _metrics; }
}
docker volume create pgdata
or you can set it to the compose file
version: "3"
services:
db:
image: postgres
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=postgress
- POSTGRES_DB=postgres
ports:
- "5433:5432"
volumes:
- pgdata:/var/lib/postgresql/data
networks:
- suruse
volumes:
pgdata:
It will create volume name pgdata and mount this volume to container's path.
docker volume inspect pgdata
// output will be
[
{
"Driver": "local",
"Labels": {},
"Mountpoint": "/var/lib/docker/volumes/pgdata/_data",
"Name": "pgdata",
"Options": {},
"Scope": "local"
}
]
The PrintWriter
class can actually create the file for you.
This example works in JDK 1.7+.
// This will create the file.txt in your working directory.
PrintWriter printWriter = null;
try {
printWriter = new PrintWriter("file.txt", "UTF-8");
// The second parameter determines the encoding. It can be
// any valid encoding, but I used UTF-8 as an example.
} catch (FileNotFoundException | UnsupportedEncodingException error) {
error.printStackTrace();
}
printWriter.println("Write whatever you like in your file.txt");
// Make sure to close the printWriter object otherwise nothing
// will be written to your file.txt and it will be blank.
printWriter.close();
For a list of valid encodings, see the documentation.
Alternatively, you can just pass the file path to the PrintWriter
class without declaring the encoding.
I have a rotating image using the same thing as you:
.knoop1 img{

-moz-transition-property: -moz-transform;
-o-transition-property: -o-transform;
transition-property: transform;
overflow:hidden;
}
.knoop1:hover img{

-moz-transform:rotate(360deg);
-o-transform:rotate(360deg);
}
Swift 3 UILabel extention
Tip: If you need some space between the image and the text just use a space or two before the labelText.
extension UILabel {
func addIconToLabel(imageName: String, labelText: String, bounds_x: Double, bounds_y: Double, boundsWidth: Double, boundsHeight: Double) {
let attachment = NSTextAttachment()
attachment.image = UIImage(named: imageName)
attachment.bounds = CGRect(x: bounds_x, y: bounds_y, width: boundsWidth, height: boundsHeight)
let attachmentStr = NSAttributedString(attachment: attachment)
let string = NSMutableAttributedString(string: "")
string.append(attachmentStr)
let string2 = NSMutableAttributedString(string: labelText)
string.append(string2)
self.attributedText = string
}
}

please try this, in this code i m trying to change the background of button on button click this works fine.
#include<stdio.h>
int main()
{
char str[100];
scanf("%[^\n]s",str);
printf("%s",str);
return 0;
}
input: read the string
ouput: print the string
This code prints the string with gaps as shown above.
The below code worked for me :)
window.open('your current page URL', '_self', '');
window.close();
I had the same issue (on Win XP), I updated the libcurl-4.dll file in my Git bin directory to the SSL version from http://www.paehl.com/open_source/?download=curl_DLL_ONLY.7z (renaming to libcurl4.dll). All working ok now.
If you don't already have a JSONArray object, call
JSONArray jsonArray = new JSONArray(jsonArrayString);
Then simply loop through that, building your own array. This code assumes it's an array of strings, it shouldn't be hard to modify to suit your particular array structure.
List<String> list = new ArrayList<String>();
for (int i=0; i<jsonArray.length(); i++) {
list.add( jsonArray.getString(i) );
}

This is an older post, but I do have a better solution. Create a form containing all of your post values as hidden fields and give the form a name such as:
<form name="RefreshForm" method="post" action="http://yoursite/yourscript">
<input type="hidden" name="postVariable" value="PostData">
</form>
Then all you need to do in your setTimeout
is RefreshForm.submit();
Cheers!
.row {
letter-spacing: -.31em;
word-spacing: -.43em;
}
.col-md-4 {
float: none;
display: inline-block;
vertical-align: middle;
}
Note: .col-md-4 could be any grid column, its just an example here.
Here is a compact and a bit cleaner version of the same pure Javascript (not a jQuery) solution as discussed above by @redsquare and @SolutionYogi (re: adding onclick
event handlers to all HTML table rows) that works in all major Web Browsers, including the latest IE11:
function addRowHandlers() {
var rows = document.getElementById("tableId").rows;
for (i = 0; i < rows.length; i++) {
rows[i].onclick = function(){ return function(){
var id = this.cells[0].innerHTML;
alert("id:" + id);
};}(rows[i]);
}
}
window.onload = addRowHandlers();
Working DEMO
Note: in order to make it work in IE8 as well, instead of this
pointer use the explicit identifier like function(myrow)
as suggested by @redsquare.
Best regards,
There are several cases to consider.
void modifies(T ¶m);
// vs
void modifies(T *param);
This case is mostly about style: do you want the code to look like call(obj) or call(&obj)? However, there are two points where the difference matters: the optional case, below, and you want to use a reference when overloading operators.
void modifies(T *param=0); // default value optional, too
// vs
void modifies();
void modifies(T ¶m);
void uses(T const ¶m);
// vs
void uses(T param);
This is the interesting case. The rule of thumb is "cheap to copy" types are passed by value — these are generally small types (but not always) — while others are passed by const ref. However, if you need to make a copy within your function regardless, you should pass by value. (Yes, this exposes a bit of implementation detail. C'est le C++.)
void uses(T const *param=0); // default value optional, too
// vs
void uses();
void uses(T const ¶m); // or optional(T param)
There's the least difference here between all situations, so choose whichever makes your life easiest.
void f(T);
void f(T const);
These declarations are actually the exact same function! When passing by value, const is purely an implementation detail. Try it out:
void f(int);
void f(int const) { /* implements above function, not an overload */ }
typedef void NC(int); // typedefing function types
typedef void C(int const);
NC *nc = &f; // nc is a function pointer
C *c = nc; // C and NC are identical types
The non-greedy regex modifiers are like their greedy counter-parts but with a ?
immediately following them:
* - zero or more
*? - zero or more (non-greedy)
+ - one or more
+? - one or more (non-greedy)
? - zero or one
?? - zero or one (non-greedy)
Aside from @JsonIgnore

on class may be usefulThanks everyone. I found a base implementation of a Json Web Token and expanded on it with the Google flavor. I still haven't gotten it completely worked out but it's 97% there. This project lost it's steam, so hopefully this will help someone else get a good head-start:
Note: Changes I made to the base implementation (Can't remember where I found it,) are:
- Changed HS256 -> RS256
- Swapped the JWT and alg order in the header. Not sure who got it wrong, Google or the spec, but google takes it the way It is below according to their docs.

Console.WriteLine(pay);
MSDN References:
Actually, I've been looking at the various ways to do this "infinite" pagination, and even though the human notion of time is that it is infinite (even though we have a notion of the beginning and end of time), computers deal in the discrete. There is a minimum and maximum time (that can be adjusted as time goes on, remember the basis of the Y2K scare?).
Anyways, the point of this discussion is that it is/should be sufficient to support a relatively infinite date range through an actually finite date range. A great example of this is the Android framework's CalendarView
implementation, and the WeeksAdapter
within it. The default minimum date is in 1900 and the default maximum date is in 2100, this should cover 99% of the calendar use of anyone within a 10 year radius around today easily.
What they do in their implementation (focused on weeks) is compute the number of weeks between the minimum and maximum date. This becomes the number of pages in the pager. Remember that the pager doesn't need to maintain all of these pages simultaneously (setOffscreenPageLimit(int)
), it just needs to be able to create the page based on the page number (or index/position). In this case the index is the number of weeks that the week is from the minimum date. With this approach you just have to maintain the minimum date and the number of pages (distance to the maximum date), then for any page you can easily compute the week associated with that page. No dancing around the fact that ViewPager
doesn't support looping (a.k.a infinite pagination), and trying to force it to behave like it can scroll infinitely.
new FragmentStatePagerAdapter(getFragmentManager()) {
@Override
public Fragment getItem(int index) {
final Bundle arguments = new Bundle(getArguments());
final Calendar temp_calendar = Calendar.getInstance();
temp_calendar.setTimeInMillis(_minimum_date.getTimeInMillis());
temp_calendar.setFirstDayOfWeek(_calendar.getStartOfWeek());
temp_calendar.add(Calendar.WEEK_OF_YEAR, index);
// Moves to the first day of this week
temp_calendar.add(Calendar.DAY_OF_YEAR,
-UiUtils.modulus(temp_calendar.get(Calendar.DAY_OF_WEEK) - temp_calendar.getFirstDayOfWeek(),
7));
arguments.putLong(KEY_DATE, temp_calendar.getTimeInMillis());
return Fragment.instantiate(getActivity(), WeekDaysFragment.class.getName(), arguments);
}
@Override
public int getCount() {
return _total_number_of_weeks;
}
};
Then WeekDaysFragment
can easily display the week starting at the date passed in its arguments.
Alternatively, it seems that some version of the Calendar app on Android uses a ViewSwitcher
(which means there's only 2 pages, the one you see and the hidden page). It then changes the transition animation based on which way the user swiped and renders the next/previous page accordingly. In this way you get infinite pagination because it just switching between two pages infinitely. This requires using a View
for the page though, which is way I went with the first approach.
In general, if you want "infinite pagination", it's probably because your pages are based off of dates or times somehow. If this is the case consider using a finite subset of time that is relatively infinite instead. This is how CalendarView
is implemented for example. Or you can use the ViewSwitcher
approach. The advantage of these two approaches is that neither does anything particularly unusual with the ViewSwitcher
or ViewPager
, and doesn't require any tricks or reimplementation to coerce them to behave infinitely (ViewSwitcher
is already designed to switch between views infinitely, but ViewPager
is designed to work on a finite, but not necessarily constant, set of pages).
If this problem comes on a Windows machine, do the following.
Here, i'm creating instance of my class
No, you are not creating the instance of your abstract class here. Rather you are creating an instance of an anonymous subclass of your abstract class. And then you are invoking the method on your abstract class reference pointing to subclass object.
This behaviour is clearly listed in JLS - Section # 15.9.1: -
If the class instance creation expression ends in a class body, then the class being instantiated is an anonymous class. Then:
- If T denotes a class, then an anonymous direct subclass of the class named by T is declared. It is a compile-time error if the class denoted by T is a final class.
- If T denotes an interface, then an anonymous direct subclass of Object that implements the interface named by T is declared.
- In either case, the body of the subclass is the ClassBody given in the class instance creation expression.
- The class being instantiated is the anonymous subclass.
Emphasis mine.
Also, in JLS - Section # 12.5, you can read about the Object Creation Process. I'll quote one statement from that here: -
Whenever a new class instance is created, memory space is allocated for it with room for all the instance variables declared in the class type and all the instance variables declared in each superclass of the class type, including all the instance variables that may be hidden.
Just before a reference to the newly created object is returned as the result, the indicated constructor is processed to initialize the new object using the following procedure:
You can read about the complete procedure on the link I provided.
To practically see that the class being instantiated is an Anonymous SubClass, you just need to compile both your classes. Suppose you put those classes in two different files:
My.java:
abstract class My {
public void myMethod() {
System.out.print("Abstract");
}
}
Poly.java:
class Poly extends My {
public static void main(String a[]) {
My m = new My() {};
m.myMethod();
}
}
Now, compile both your source files:
javac My.java Poly.java
Now in the directory where you compiled the source code, you will see the following class files:
My.class
Poly$1.class // Class file corresponding to anonymous subclass
Poly.class
See that class - Poly$1.class
. It's the class file created by the compiler corresponding to the anonymous subclass you instantiated using the below code:
new My() {};
So, it's clear that there is a different class being instantiated. It's just that, that class is given a name only after compilation by the compiler.
In general, all the anonymous subclasses in your class will be named in this fashion:
Poly$1.class, Poly$2.class, Poly$3.class, ... so on
Those numbers denote the order in which those anonymous classes appear in the enclosing class.
This function will clone remote repo into local repo dir, after merging all commits will be saved, git log
will be show the original commits and proper paths:
function git-add-repo
{
repo="$1"
dir="$(echo "$2" | sed 's/\/$//')"
path="$(pwd)"
tmp="$(mktemp -d)"
remote="$(echo "$tmp" | sed 's/\///g'| sed 's/\./_/g')"
git clone "$repo" "$tmp"
cd "$tmp"
git filter-branch --index-filter '
git ls-files -s |
sed "s,\t,&'"$dir"'/," |

git pull "$remote/master"
git merge --allow-unrelated-histories -m "Merge repo $repo into master" --edit "$remote/master"
git remote remove "$remote"
rm -rf "$tmp"
}
How to use:
cd current/package
git-add-repo https://github.com/example/example dir/to/save
If make a little changes you can even move files/dirs of merged repo into different paths, for example:
repo="https://github.com/example/example"
path="$(pwd)"
tmp="$(mktemp -d)"
remote="$(echo "$tmp" | sed 's/\///g' | sed 's/\./_/g')"
git clone "$repo" "$tmp"
cd "$tmp"

Paths replaces via sed
, so make sure it moved in proper paths after merging.
The --allow-unrelated-histories
parameter only exists since git >= 2.9.
I found the Chrome app "Advanced REST Client" excellent to work with REST services. You can set the Content-Type to application/json
among other things:
Advanced REST client
This excellent answer explains very well what is happening and provides a solution. I would like to add another solution that might be suitable in similar cases: using the query
method:
result = result.query("(var > 0.25) or (var < -0.25)")
See also http://pandas.pydata.org/pandas-docs/stable/indexing.html#indexing-query.
(Some tests with a dataframe I'm currently working with suggest that this method is a bit slower than using the bitwise operators on series of booleans: 2 ms vs. 870 µs)
A piece of warning: At least one situation where this is not straightforward is when column names happen to be python expressions. I had columns named WT_38hph_IP_2
, WT_38hph_input_2
and log2(WT_38hph_IP_2/WT_38hph_input_2)
and wanted to perform the following query: "(log2(WT_38hph_IP_2/WT_38hph_input_2) > 1) and (WT_38hph_IP_2 > 20)"
I obtained the following exception cascade:
KeyError: 'log2'
UndefinedVariableError: name 'log2' is not defined
ValueError: "log2" is not a supported function
I guess this happened because the query parser was trying to make something from the first two columns instead of identifying the expression with the name of the third column.
A possible workaround is proposed here.
Just change the DropDownStyle
to DropDownList
. Or if you want it completely read only you can set Enabled = false
, or if you don't like the look of that I sometimes have two controls, one readonly textbox and one combobox and then hide the combo and show the textbox if it should be completely readonly and vice versa.
Here is another simple way.
var es, log, logFile;
es = require('event-stream');
log = require('gulp-util').log;
logFile = function(es) {
return es.map(function(file, cb) {
log(file.path);
return cb();
});
};
gulp.task("do", function() {
return gulp.src('./examples/*.html')
.pipe(logFile(es))
.pipe(gulp.dest('./build'));
});

getElementsByClassName()
returns HTMLCollection so you could try this
var button = document.getElementsByClassName("navButton")[0];
Edit
var buttons = document.getElementsByClassName("navButton");
for(i=0;buttons.length;i++){
buttons[i].onmouseover = function(){
this.className += ' active' //add class
this.setAttribute("src", "images/arrows/top_o.png");
}
}
For lists, use enumerate

print(field, possible_values)
iteritems

I faced this issue in my code. I only put this code in my app.module.ts.
import { HttpModule } from '@angular/http';
@NgModule({
imports: [ BrowserModule, HttpModule ],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
once again Make sure these 2 things happen correctly nothing more than that. (FOR ECLIPSE USERS)
1) copy the jar file from --> C:\Users(your-username)\android-sdks\extras\google\google_play_services\libproject\google-play-services_lib\libs\ google-play-services.jar
2) Right Click Project--> Build Path -> Add External Archive-> google-play-services.jar
Add this line to your AndroidManifest.xml:
<activity android:name=".OrderScreen" />
strSearch in this case is probably null (not simply empty).
Try using
String.IsNullOrEmpty(strSearch)
if you are just trying to determine if the string doesn't have any contents.
You can also use rowcount, but TOP is probably better and cleaner, hence the upvote for Mehrdad
SET ROWCOUNT 10
SELECT * FROM dbo.Orders

As geofflane mentions in his answer, Java 7 now support named groups.
tchrist points out in the comment that the support is limited.
He details the limitations in his great answer "Java Regex Helper"
Java 7 regex named group support was presented back in September 2010 in Oracle's blog.
In the official release of Java 7, the constructs to support the named capturing group are:
(?<name>capturing text)
to define a named group "name"\k<name>
to backreference a named group "name"${name}
to reference to captured group in Matcher's replacement stringMatcher.group(String name)
to return the captured input subsequence by the given "named group".
Other alternatives for pre-Java 7 were:
(Original answer: Jan 2009, with the next two links now broken)
You can not refer to named group, unless you code your own version of Regex...
That is precisely what Gorbush2 did in this thread.
(limited implementation, as pointed out again by tchrist, as it looks only for ASCII identifiers. tchrist details the limitation as:
only being able to have one named group per same name (which you don’t always have control over!) and not being able to use them for in-regex recursion.
Note: You can find true regex recursion examples in Perl and PCRE regexes, as mentioned in Regexp Power, PCRE specs and Matching Strings with Balanced Parentheses slide)
Example:
String:
"TEST 123"
RegExp:
"(?<login>\\w+) (?<id>\\d+)"
Access
matcher.group(1) ==> TEST
matcher.group("login") ==> TEST
matcher.name(1) ==> login
Replace
matcher.replaceAll("aaaaa_$1_sssss_$2____") ==> aaaaa_TEST_sssss_123____
matcher.replaceAll("aaaaa_${login}_sssss_${id}____") ==> aaaaa_TEST_sssss_123____
(extract from the implementation)

You do not need to use 64bit since windows will emulate 32bit programs using wow64. But using the native version (64bit) will give you more performance.
I would recommend background-size: cover;
if you don't want your background to lose its proportions: JS Fiddle
html {
background: url(image/path) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}

A lot of these answers are pretty old, so I thought I would update with a solution that I think is helpful.
Our issue was similar to OP's, we upgraded 32 bit XP machines to 64 bit windows 7 and our application software that uses a 32 bit ODBC driver stopped being able to write to our database.
Turns out, there are two ODBC Data Source Managers, one for 32 bit and one for 64 bit. So I had to run the 32 bit version which is found in C:\Windows\SysWOW64\odbcad32.exe. Inside the ODBC Data Source Manager, I was able to go to the System DSN tab and Add my driver to the list using the Add button. (You can check the Drivers tab to see a list of the drivers you can add, if your driver isn't in this list then you may need to install it).
The next issue was the software that we ran was compiled to use 'Any CPU'. This would see the operating system was 64 bit, so it would look at the 64 bit ODBC Data Sources. So I had to force the program to compile as an x86 program, which then tells it to look at the 32 bit ODBC Data Sources. To set your program to x86, in Visual Studio go to your project properties and under the build tab at the top there is a platform drop down list, and choose x86. If you don't have the source code and can't compile the program as x86, you might be able to right click the program .exe and go to the compatibility tab and choose a compatibility that works for you.
Once I had the drivers added and the program pointing to the right drivers, everything worked like it use to. Hopefully this helps anyone working with older software.

{
var element = document.createElement("div");
element.appendChild(document.createTextNode('The man who mistook his wife for a hat'));
document.getElementById('lc').appendChild(element);

}
if we make the particular activity
as
android:exported="true"
it will be the launching activity

Click on the module name just to the left of the run button
and click on "Edit configurations..." Now make sure "Launch default Activity"
is selected.
flex: 1
means the following:
flex-grow : 1; ? The div will grow in same proportion as the window-size
flex-shrink : 1; ? The div will shrink in same proportion as the window-size
flex-basis : 0; ? The div does not have a starting value as such and will
take up screen as per the screen size available for
e.g:- if 3 divs are in the wrapper then each div will take 33%.
Connections have a close
method as specified in PEP-249 (Python Database API Specification v2.0):
import pyodbc
conn = pyodbc.connect('DRIVER=MySQL ODBC 5.1 driver;SERVER=localhost;DATABASE=spt;UID=who;PWD=testest')
csr = conn.cursor()
csr.close()
conn.close() #<--- Close the connection
Since the pyodbc
connection and cursor are both context managers, nowadays it would be more convenient (and preferable) to write this as:
import pyodbc
conn = pyodbc.connect('DRIVER=MySQL ODBC 5.1 driver;SERVER=localhost;DATABASE=spt;UID=who;PWD=testest')
with conn:
crs = conn.cursor()
do_stuff
# conn.commit() will automatically be called when Python leaves the outer `with` statement
# Neither crs.close() nor conn.close() will be called upon leaving the `with` statement!!
See https://github.com/mkleehammer/pyodbc/issues/43 for an explanation for why conn.close() is not called.
Note that unlike the original code, this causes conn.commit()
to be called. Use the outer with
statement to control when you want commit
to be called.
Also note that regardless of whether or not you use the with
statements, per the docs,
Connections are automatically closed when they are deleted (typically when they go out of scope) so you should not normally need to call [
conn.close()
], but you can explicitly close the connection if you wish.
and similarly for cursors (my emphasis):
Cursors are closed automatically when they are deleted (typically when they go out of scope), so calling [
csr.close()
] is not usually necessary.
You're right that the SD Card directory is /sdcard
but you shouldn't be hard coding it. Instead, make a call to Environment.getExternalStorageDirectory()
to get the directory:
File sdDir = Environment.getExternalStorageDirectory();
If you haven't done so already, you will need to give your app the correct permission to write to the SD Card by adding the line below to your Manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
From JQuery Documentation
The jqXHR objects returned by $.ajax()
as of jQuery 1.5 implement the Promise interface, giving them all the properties, methods, and behavior of a Promise (see Deferred object for more information). These methods take one or more function arguments that are called when the $.ajax()
request terminates. This allows you to assign multiple callbacks on a single request, and even to assign callbacks after the request may have completed. (If the request is already complete, the callback is fired immediately.) Available Promise methods of the jqXHR object include:
jqXHR.done(function( data, textStatus, jqXHR ) {});
An alternative construct to the success callback option, refer to deferred.done()
for implementation details.
jqXHR.fail(function( jqXHR, textStatus, errorThrown ) {});
An alternative construct to the error callback option, the .fail()
method replaces the deprecated .error() method. Refer to deferred.fail() for implementation details.
jqXHR.always(function( data|jqXHR, textStatus, jqXHR|errorThrown ) { });
(added in jQuery 1.6)
An alternative construct to the complete callback option, the .always()
method replaces the deprecated .complete()
method.
In response to a successful request, the function's arguments are the same as those of .done()
: data, textStatus, and the jqXHR object. For failed requests the arguments are the same as those of .fail()
: the jqXHR object, textStatus, and errorThrown. Refer to deferred.always()
for implementation details.
jqXHR.then(function( data, textStatus, jqXHR ) {}, function( jqXHR, textStatus, errorThrown ) {});
Incorporates the functionality of the .done()
and .fail()
methods, allowing (as of jQuery 1.8) the underlying Promise to be manipulated. Refer to deferred.then()
for implementation details.
Deprecation Notice: The
jqXHR.success()
,jqXHR.error()
, andjqXHR.complete()
callbacks are removed as of jQuery 3.0. You can usejqXHR.done()
,jqXHR.fail()
, andjqXHR.always()
instead.
Either decode them using html_entity_decode
or remove them using preg_replace
:
$Content = preg_replace("/&#?[a-z0-9]+;/i","",$Content);
(From here)
EDIT: Alternative according to Jacco's comment
might be nice to replace the '+' with {2,8} or something. This will limit the chance of replacing entire sentences when an unencoded '&' is present.
$Content = preg_replace("/&#?[a-z0-9]{2,8};/i","",$Content);
Try this:
function createcodes() {
$('.authors-list tr').each(function () {
//processing this row
//how to process each cell(table td) where there is checkbox
$(this).find('td input:checked').each(function () {
// it is checked, your code here...
});
});
}
like so:
BEGIN TRANSACTION;
UPDATE table_name
SET column_name=REPLACE(column_name,'text_to_find','replace_with_this');
COMMIT TRANSACTION;
Example: Replaces <script... with <a ... to eliminate javascript vulnerabilities
BEGIN TRANSACTION; UPDATE testdb
SET title=REPLACE(title,'script','a'); COMMIT TRANSACTION;
I found a good choice to be coc.nvim with the python language server.
It takes a bit of effort to set up. I got frustrated with jedi-vim, because it would always freeze vim for a bit when completing. coc.nvim doesn't do it because it's asyncronous, meaning that . It also gives you linting for your code. It supports many other languages and is highly configurable.
The python language server uses jedi so you get the same completion as you would get from jedi.
I haven't tried it but if you put a div in your table cell set so that it will have scrollbars if needed, then you could insert in there, with a fixed height on the div and it should keep your table row to a fixed height.
I think that once you've imported it, the behaviour is the same (in the place your variable will be used outside source file).
The only difference would be if you try to reassign it before the end of this very file.
You need to use ref
if you plan to read and write to the parameter. You need to use out
if you only plan to write. In effect, out
is for when you'd need more than one return value, or when you don't want to use the normal return mechanism for output (but this should be rare).
There are language mechanics that assist these use cases. Ref
parameters must have been initialized before they are passed to a method (putting emphasis on the fact that they are read-write), and out
parameters cannot be read before they are assigned a value, and are guaranteed to have been written to at the end of the method (putting emphasis on the fact that they are write only). Contravening to these principles results in a compile-time error.
int x;
Foo(ref x); // error: x is uninitialized
void Bar(out int x) {} // error: x was not written to
For instance, int.TryParse
returns a bool
and accepts an out int
parameter:
int value;
if (int.TryParse(numericString, out value))
{
/* numericString was parsed into value, now do stuff */
}
else
{
/* numericString couldn't be parsed */
}
This is a clear example of a situation where you need to output two values: the numeric result and whether the conversion was successful or not. The authors of the CLR decided to opt for out
here since they don't care about what the int
could have been before.
For ref
, you can look at Interlocked.Increment
:
int x = 4;
Interlocked.Increment(ref x);
Interlocked.Increment
atomically increments the value of x
. Since you need to read x
to increment it, this is a situation where ref
is more appropriate. You totally care about what x
was before it was passed to Increment
.
In the next version of C#, it will even be possible to declare variable in out
parameters, adding even more emphasis on their output-only nature:
if (int.TryParse(numericString, out int value))
{
// 'value' exists and was declared in the `if` statement
}
else
{
// conversion didn't work, 'value' doesn't exist here
}

for (int i = 0; i < list.size(); i++) {
Object o = list.get(i);
if(i>0){
json+=",";
}
json+="{\"label\":\""+getLabel.invoke(o,args)+"\",\"name\":\""+getName.invoke(o,args)+"\"}";
//System.out.println("Object = " + i+" -> "+o.getNumber());
}
json+="]";
return json;
} catch (ClassNotFoundException ex) {
Logger.getLogger(JSONHelper.class.getName()).log(Level.SEVERE, null, ex);
} catch (Exception ex) {
System.out.println("Error in get JSON List");
ex.printStackTrace();
}
return "";
}
and call it from anywhere like :
String toreturn=JSONHelper.getJSONList(list, "com.bean.Contact", "getContactID", "getNumber");

It is valuable to additionally note, that PHP will populate all the $_GET
parameters even when you send a proper request of other type.
Methods in above replies are completely correct, however if you want to additionaly check for GET
parameters while handling POST
, DELETE
, PUT
, etc. request, you need to check the size of $_GET
array.

Related to this I had to find a fix where animated gifs were used as a background image to ensure styling was kept to the stylesheet. A similar fix worked for me there too... my script went something like this (I'm using jQuery to make it easier to get the computed background style - how to do that without jQuery is a topic for another post):
var spinner = <give me a spinner element>
window.onbeforeunload = function() {
bg_image = $(spinner).css('background-image');
spinner.style.backgroundImage = 'none';
spinner.style.backgroundImage = bg_image;
}
[EDIT] With a bit more testing I've just realised that this doesn't work with background images in IE8. I've been trying everything I can think of to get IE8 to render a gif animation wile loading a page, but it doesn't look possible at this time.
Another option is to split off the textarea in the Site.css as follows:

}
textarea {
/*max-width: 280px;*/

also (in my MVC 5) add ref to textarea:
@Html.TextAreaFor(model => ................... @class = "form-control", @id="textarea"............
It worked for me
You can use double splat operator which is available since Ruby 2.0:
h = { a: 1, b: 2 }
h = { **h, c: 3 }
p h
# => {:a=>1, :b=>2, :c=>3}
FYI: it looks like you might have an infinite loop in your example...
if cnt > 0 and len(aStr) > 1:
while cnt > 0:
aStr = aStr[1:]+aStr[0]
cnt += 1
cnt
is greater than 0cnt
is greater than 0cnt
by 1The net result is that cnt
will always be greater than 0 and the loop will never exit.
If you have the XML stored inside a string variable you could use a StringReader:
var xml = @"<car/>";
var serializer = new XmlSerializer(typeof(Car));
using (var reader = new StringReader(xml))
{
var car = (Car)serializer.Deserialize(reader);
}
A simpler way would be to do:
ObjectA.Verify(
a => a.Execute(
It.Is<Params>(p => p.Id == 7)
)
);
I am working on C# 9 and .NET 5, example
foo
is nullable int, I need get int value of foo
var foo = (context as AccountTransfer).TransferSide;
int value2 = 0;
if (foo != null)
{
value2 = foo.Value;
}
fill
all items with undefined
before using map
:?? Array.fill
has no IE support
// run 5 times:
Array(5).fill().map((item, i)=>{
console.log(i) // print index
})
_x000D_
There is nice "trick" using destructuring Array, replacing fill
with:
Array(5).fill()
? [...Array(5)]
which does the same, filling the array with undefined
.
If you want to make the above more "declarative", my currently opinion-based solution would be:
const iterate = times => callback => [...Array(times)].map((n,i) => callback(i))
iterate(3)(console.log)
_x000D_
// run 5 times:
for( let i=5; i--; )
console.log(i)
_x000D_
Or as a declarative "while":
const times = count => callback => { while(count--) callback(count) }
times(3)(console.log)
_x000D_
Use:
class UtilSingleton: NSObject {
var iVal: Int = 0
class var shareInstance: UtilSingleton {
get {
struct Static {
static var instance: UtilSingleton? = nil
static var token: dispatch_once_t = 0
}
dispatch_once(&Static.token, {
Static.instance = UtilSingleton()
})
return Static.instance!
}
}
}
How to use:
UtilSingleton.shareInstance.iVal++
println("singleton new iVal = \(UtilSingleton.shareInstance.iVal)")
If, like me, you would just prefer people didn't click out to youtube using the logo, one option is to use a player like jwplayer. Using jwplayer the logo is still there just unclickable.
Your concatenation syntax is correct.
Most likely the callback function isn't even being called. You can test that by putting an alert()
, console.log()
or debugger
line in that function.
If it isn't being called, most likely there's an AJAX error. Look at chaining a .fail()
handler after $.post()
to find out what the error is, e.g.:
$.post('ajaxskeleton.php', {
red: text
}, function(){
$('#part' + number).html(text);
}).fail(function(jqXHR, textStatus, errorThrown) {
console.log(arguments);
});
You could use method
javax.crypto.Cipher.getMaxAllowedKeyLength(String transformation)
to test the available key length, use that and inform the user about what is going on. Something stating that your application is falling back to 128 bit keys due to the policy files not being installed, for example. Security conscious users will install the policy files, others will continue using weaker keys.
Given this .env
file:
DB_NAME=foo
DB_USER=bar
DB_PASSWORD=baz
And this mongo-init.sh
file:
mongo --eval "db.auth('$MONGO_INITDB_ROOT_USERNAME', '$MONGO_INITDB_ROOT_PASSWORD'); db = db.getSiblingDB('$DB_NAME'); db.createUser({ user: '$DB_USER', pwd: '$DB_PASSWORD', roles: [{ role: 'readWrite', db: '$DB_NAME' }] });"
This docker-compose.yml
will create the admin database and admin user, authenticate as the admin user, then create the real database and add the real user:

Yes. Importing CSS file into another CSS file is possible.
It must be the first rule in the style sheet using the @import rule.
@import "mystyle.css";
@import url("mystyle.css");
The only caveat is that older web browsers will not support it. In fact, this is one of the CSS 'hack' to hide CSS styles from older browsers.
Refer to this list for browser support.
A different way:
public boolean contains(final int[] array, final int key) {
Arrays.sort(array);
return Arrays.binarySearch(array, key) >= 0;
}
This modifies the passed-in array. You would have the option to copy the array and work on the original array i.e. int[] sorted = array.clone();
But this is just an example of short code. The runtime is O(NlogN)
while your way is O(N)
You can't have a non-keyword argument after a keyword argument.
Make sure you re-arrange your function arguments like so:
def a(len1,til,hgt=len1,col=0):
system('mode con cols='+len1,'lines='+hgt)
system('title',til)
system('color',col)
a(64,"hi",25,"0b")
Another way to turn off CSRF that won't render a null session is to add:
skip_before_action :verify_authenticity_token
in your Rails Controller. This will ensure you still have access to session info.
Again, make sure you only do this in API controllers or in other places where CSRF protection doesn't quite apply.
If you have control over your server, you can use PHP:
<?PHP
header('Access-Control-Allow-Origin: *');
?>

If your code doesn't require the file to be truncated first, you can use the FileMode.OpenOrCreate to open the filestream, which will create the file if it doesn't exist or open it if it does. You can use the stream to point at the front and start overwriting the existing file?
I'm assuming your using a streams here, there are other ways to write a file.
You need to use
$rootScope.$broadcast()
in the controller that must send datas. And in the one that receive those datas, you use
$scope.$on
Here is a fiddle that i forked a few time ago (I don't know who did it first anymore
Thanks to all example providers, some worked for some not. Below is another simple example format that worked for me.
echo "Sample body" | mail -s "Test email" [email protected] [email protected]
There are a few ways to do this.
The first is the most widely used. It works on all major browsers.
input[readonly] {
background-color: #dddddd;
}
While the one above will select all inputs with readonly
attached, this one below will select only what you desire. Make sure to replace demo
with whatever input type you want.
input[type="demo"]:read-only {
background-color: #dddddd;
}
This is an alternate to the first, but it's not used a whole lot:
input:read-only {
background-color: #dddddd;
}
The :read-only
selector is supported in Chrome, Opera, and Safari. Firefox uses :-moz-read-only
. IE doesn't support the :read-only
selector.
You can also use input[readonly="readonly"]
, but this is pretty much the same as input[readonly]
, from my experience.
Any decent text editor has a search&replace facility that supports regular expressions.
If however, you have reason to reinvent the wheel in Java, you can do:
Path path = Paths.get("test.txt");
Charset charset = StandardCharsets.UTF_8;
String content = new String(Files.readAllBytes(path), charset);
content = content.replaceAll("foo", "bar");
Files.write(path, content.getBytes(charset));
This only works for Java 7 or newer. If you are stuck on an older Java, you can do:
String content = IOUtils.toString(new FileInputStream(myfile), myencoding);
content = content.replaceAll(myPattern, myReplacement);
IOUtils.write(content, new FileOutputStream(myfile), myencoding);
In this case, you'll need to add error handling and close the streams after you are done with them.
IOUtils
is documented at http://commons.apache.org/proper/commons-io/javadocs/api-release/org/apache/commons/io/IOUtils.html
I know this is old but if it helps you could use moment and moment time zone. If you haven't seen them take a look.
two really handy time manipulation libraries.
Ran into a similar issue with nodemon running through docker,
it'd be worth checking that your "main" file in your package.json is configured to point at the correct entry point
in package.json
"main": "server.js",
"scripts": {
"start":"nodemon src/server.js",
"docker:build": "docker build -f ./docker/Dockerfile . "
},
Action normally specifies the file/page that the form is submitted to (using the method described in the method paramater (post, get etc.))
An action of #
indicates that the form stays on the same page, simply suffixing the url with a #
. Similar use occurs in anchors. <a href=#">Link</a>
for example, will stay on the same page.
Thus, the form is submitted to the same page, which then processes the data etc.
You can use format strings as well.
string time = DateTime.Now.ToString("hh:mm:ss"); // includes leading zeros
string date = DateTime.Now.ToString("dd/MM/yy"); // includes leading zeros
or some shortcuts if the format works for you
string time = DateTime.Now.ToShortTimeString();
string date = DateTime.Now.ToShortDateString();
Either should work.
You can copy this in a module:
Sub WaitFor(NumOfSeconds As Long)
Dim SngSec as Long
SngSec=Timer + NumOfSeconds
Do while timer < sngsec
DoEvents
Loop
End sub
and whenever you want to apply the pause write:
Call WaitFor(1)
I hope that helps!
An MSI is a Windows Installer database. Windows Installer (a service installed with Windows) uses this to install software on your system (i.e. copy files, set registry values, etc...).
A setup.exe may either be a bootstrapper or a non-msi installer. A non-msi installer will extract the installation resources from itself and manage their installation directly. A bootstrapper will contain an MSI instead of individual files. In this case, the setup.exe will call Windows Installer to install the MSI.
Some reasons you might want to use a setup.exe:

Solution using just POST - no $_SESSION

$textarea1 = ""; // set var to avoid errors
if(isset($_POST['textarea1'])){
$textarea1 = $_POST['textarea1']
}
?>
<textarea><?php echo $textarea1;?></textarea>
Solution using $_SESSION and POST
page1.php
<?php
session_start(); // needs to be before anything else on page to use $_SESSION
$textarea1 = "";
if(isset($_POST['textarea1'])){
$_SESSION['textarea1'] = $_POST['textarea1'];

session_start(); // needs to be before anything else on page to use $_SESSION
// this page outputs the textarea1 from the session IF it exists
$textarea1 = ""; // set var to avoid errors

Currently there is no way to do this with apps running in WSL2. However there are two work-arounds:
The debug window retains the contents of the WSL shell window that closed.
The window remains open if your application returns a non-zero return code, so you could return non-zero in debug builds for example.
Another options with purrr
package:
library(dplyr)
df <- data.frame(a = NA,
b = seq(1:5),
c = c(rep(1, 4), NA))
df %>% purrr::discard(~all(is.na(.)))
df %>% purrr::keep(~!all(is.na(.)))
select * from this_table;
select distinct person from this_table
union select address as location from that_table
drop wrong_table from this_database;

Reference article: Show red color border for invalid input fields angualrjs
I used ng-class on all input fields.like below
<input type="text" ng-class="{submitted:newEmployee.submitted}" placeholder="First Name" data-ng-model="model.firstName" id="FirstName" name="FirstName" required/>
when I click on save button I am changing newEmployee.submitted value to true(you can check it in my question). So when I click on save, a class named submitted gets added to all input fields(there are some other classes initially added by angularjs).
So now my input field contains classes like this
class="ng-pristine ng-invalid submitted"
now I am using below css code to show red border on all invalid input fields(after submitting the form)
input.submitted.ng-invalid
{
border:1px solid #f00;
}
Thank you !!
Update:
We can add the ng-class at the form element instead of applying it to all input elements. So if the form is submitted, a new class(submitted) gets added to the form element. Then we can select all the invalid input fields using the below selector
form.submitted .ng-invalid
{
border:1px solid #f00;
}

In your terminal type find / -name "php.ini"

the terminal and type phpinfo(); after php initiated.Here's probably what you are looking for: php-get-url-query-string. You can combine it with other suggested $_SERVER
parameters.
I'm not sure why nobody else has suggested this, but you can write a templated function that returns lambda functions. The following solved my problem, the reason I came to this page:
template <typename DATUM>
std::function<double(DATUM)> makeUnweighted() {
return [](DATUM datum){return 1.0;};
}
Now whenever I want a function that takes a given type of argument (e.g. std::string
), I just say
auto f = makeUnweighted<std::string>()
and now f("any string")
returns 1.0
.
That's an example of what I mean by "templated lambda function." (This particular case is used to automatically provide an inert weighting function when somebody doesn't want to weight their data, whatever their data might be.)
I agree with the answer by Kenny Eliasson. Go with Extension methods. Here is a brief overview of extension methods and your required IfNotNull method.
You have more static resources that the cache has room for. You can do one of the following:

That's a very general question. One answer is: "it depends what kind of UUID you wish to generate". But a better one is this: "Well, before I answer, can you tell us why you need to code up your own UUID generation algorithm instead of calling the UUID generation functionality that most modern operating systems provide?"
Doing that is easier and safer, and since you probably don't need to generate your own, why bother coding up an implementation? In that case, the answer becomes use whatever your O/S, programming language or framework provides. For example, in Windows, there is CoCreateGuid or UuidCreate or one of the various wrappers available from the numerous frameworks in use. In Linux there is uuid_generate.
If you, for some reason, absolutely need to generate your own, then at least have the good sense to stay away from generating v1 and v2 UUIDs. It's tricky to get those right. Stick, instead, to v3, v4 or v5 UUIDs.
Update:
In a comment, you mention that you are using Python and link to this. Looking through the interface provided, the easiest option for you would be to generate a v4 UUID (that is, one created from random data) by calling uuid.uuid4()
.
If you have some data that you need to (or can) hash to generate a UUID from, then you can use either v3 (which relies on MD5) or v5 (which relies on SHA1). Generating a v3 or v5 UUID is simple: first pick the UUID type you want to generate (you should probably choose v5) and then pick the appropriate namespace and call the function with the data you want to use to generate the UUID from. For example, if you are hashing a URL you would use NAMESPACE_URL
:
uuid.uuid3(uuid.NAMESPACE_URL, 'https://ripple.com')
Please note that this UUID will be different than the v5 UUID for the same URL, which is generated like this:
uuid.uuid5(uuid.NAMESPACE_URL, 'https://ripple.com')
A nice property of v3 and v5 URLs is that they should be interoperable between implementations. In other words, if two different systems are using an implementation that complies with RFC4122, they will (or at least should) both generate the same UUID if all other things are equal (i.e. generating the same version UUID, with the same namespace and the same data). This property can be very helpful in some situations (especially in content-addressible storage scenarios), but perhaps not in your particular case.
This is a not-hard approach:
<div>
<img src="sample.jpg" />
</div>
then in css:
div {
position: absolute;
}
img, div {
width: ##%;
height: ##%;
}
Instead of using RequestContextHolder
directly, you can also use ServletUriComponentsBuilder
and its static methods:
ServletUriComponentsBuilder.fromCurrentContextPath()
ServletUriComponentsBuilder.fromCurrentServletMapping()
ServletUriComponentsBuilder.fromCurrentRequestUri()
ServletUriComponentsBuilder.fromCurrentRequest()
They use RequestContextHolder
under the hood, but provide additional flexibility to build new URLs using the capabilities of UriComponentsBuilder
.
Example:
ServletUriComponentsBuilder builder = ServletUriComponentsBuilder.fromCurrentRequestUri();
builder.scheme("https");
builder.replaceQueryParam("someBoolean", false);
URI newUri = builder.build().toUri();
It is a self-executing anonymous function. The first set of parentheses contain the expressions to be executed, and the second set of parentheses executes those expressions.
It is a useful construct when trying to hide variables from the parent namespace. All the code within the function is contained in the private scope of the function, meaning it can't be accessed at all from outside the function, making it truly private.
See:
The permission denied error probably indicates that SSH private key authentication has failed. Assuming that you're using an image derived from the Debian or Centos images recommended by gcutil, it's likely one of the following:
-i
option.There's a script that runs every minute on the standard Compute Engine Centos and Debian images which fetches the 'sshKeys' metadata entry from the metadata server, and creates accounts (with sudoers access) as necessary. This script expects entries of the form "account:\n" in the sshKeys metadata, and can put several entries into authorized_keys for a single account. (or create multiple accounts if desired)
In recent versions of the image, this script sends its output to the serial port via syslog, as well as to the local logs on the machine. You can read the last 1MB of serial port output via gcutil getserialportoutput
, which can be handy when the machine isn't responding via SSH.
gcutil ssh
works:gcutil ssh
does the following:
$HOME/.ssh/google_compute_engine
, and calls ssh-keygen
to create one if not present.sshKeys
for an entry that looks like ${USER}:$(cat $HOME/.ssh/google_compute_engine.pub)
gcutil ssh
invokes ssh
with a few command-line arguments to connect to the VM.sshKeys
, the console and command line tool won't realize that modifying sshKeys
doesn't work, and a lot of the automatic magic above can get broken.ssh
, it may not find your .ssh/google_compute_engine
key. You can fix this by using gcutil ssh
, or by copying your ssh public key (ends in .pub
) and adding to the sshKeys
entry for the project or instance in the console. (You'll also need to put in a username, probably the same as your local-machine account name.)gcutil ssh
, you probably don't have a .ssh/google_compute_engine.pub
file. You can either use ssh-keygen
to create a new SSH public/private keypair and add it to sshKeys
, as above, or use gcutil ssh
to create them and manage sshKeys
.sshKeys
entry doesn't match your local username, you may need to supply the -l
argument to SSH.Change the PATH variable to include the bin directory of your PostgreSQL installation.

It seems like your question has been answered but now you might wonder why char *a = "String" is stored in read-only memory. Well, it is actually left undefined by the c99 standard but most compilers choose to it this way for instances like:
printf("Hello, World\n");
c99 standard(pdf) [page 130, section 6.7.8]:
The declaration:
char s[] = "abc", t[3] = "abc";
defines "plain" char array objects s and t whose elements are initialized with character string literals. This declaration is identical to char
s[] = { 'a', 'b', 'c', '\0' }, t[] = { 'a', 'b', 'c' };
The contents of the arrays are modifiable. On the other hand, the declaration
char *p = "abc";
defines p with type "pointer to char" and initializes it to point to an object with type "array of char" with length 4 whose elements are initialized with a character string literal. If an attempt is made to use p to modify the contents of the array, the behavior is undefined.
Well, it generally depends on the shell. For bash
, it marks the variable as "exportable" meaning that it will show up in the environment for any child processes you run.
Non-exported variables are only visible from the current process (the shell).
From the bash
man page:
export [-fn] [name[=word]] ...
export -p
The supplied names are marked for automatic export to the environment of subsequently executed commands.
If the
-f
option is given, the names refer to functions. If no names are given, or if the-p
option is supplied, a list of all names that are exported in this shell is printed.The
-n
option causes the export property to be removed from each name.If a variable name is followed by
=word
, the value of the variable is set toword
.
export
returns an exit status of 0 unless an invalid option is encountered, one of the names is not a valid shell variable name, or-f
is supplied with a name that is not a function.
You can also set variables as exportable with the typeset
command and automatically mark all future variable creations or modifications as such, with set -a
.
It's not necessary to rewrite everything. I recommend doing this instead:
Post this inside your .m file of your custom cell.
- (void)layoutSubviews {
[super layoutSubviews];
self.imageView.frame = CGRectMake(0,0,32,32);
}
This should do the trick nicely. :]
If the array happens to be int or anything with the size of int or your mem-pattern's size fits exact times into an int (i.e. all zeroes or 0xA5A5A5A5), the best way is to use memset().
Otherwise call memcpy() in a loop moving the index.
In IPython (jupyter

They have the same effect on normal web browser rendering engines, but there is a fundamental difference between them.
As the author writes in a discussion list post:
Think of three different situations:
"Bold" is a style - when you say "bold a word", people basically know that it means to add more, let's say "ink", around the letters until they stand out more amongst the rest of the letters.
That, unfortunately, means nothing to a blind person. On mobile phones and other PDAs, text is already bold because screen resolution is very small. You can't bold a bold without screwing something up.
<b>
is a style - we know what "bold" is supposed to look like.
<strong>
however is an indication of how something should be understood. "Strong" could (and often does) mean "bold" in a browser, but it could also mean a lower tone for a speaking program like Jaws (for blind people) or be represented by an underline (since you can't bold a bold) on a Palm Pilot.
HTML was never meant to be about styles. Do some searches for "Tim Berners-Lee" and "the semantic web." <strong>
is semantic—it describes the text it surrounds (e.g., "this text should be stronger than the rest of the text you've displayed") as opposed to describing how the text it surrounds should be displayed (e.g., "this text should be bold").
Specifically, this is not rounding your result, it's truncating toward zero. So if you divide -3/2, you'll get -1 and not -2. Welcome to integral math! Back before CPUs could do floating point operations or the advent of math co-processors, we did everything with integral math. Even though there were libraries for floating point math, they were too expensive (in CPU instructions) for general purpose, so we used a 16 bit value for the whole portion of a number and another 16 value for the fraction.
EDIT: my answer makes me think of the classic old man saying "when I was your age..."
Your class shoud look something like this:
class Something { int[] array; //global array, replace type of course void function1() { array = new int[10]; //let say you declare it here that will be 10 integers in size } void function2() { array[0] = 12; //assing value at index 0 to 12. } }
That way you array will be accessible in both functions. However, you must be careful with global stuff, as you can quickly overwrite something.
You can use GeneratorOf
like this:
var fibs = ArraySlice([1, 1])
var fibGenerator = GeneratorOf{
_ -> Int? in
fibs.append(fibs.reduce(0, combine:+))
return fibs.removeAtIndex(0)
}
println(fibGenerator.next())
println(fibGenerator.next())
println(fibGenerator.next())
println(fibGenerator.next())
println(fibGenerator.next())
println(fibGenerator.next())
You can use a redirect to that action :
redirect_to your_controller_action_url
More on : Rails Guide
To just render the new action :
redirect_to your_controller_action_url and return
My error was:
duplicate output file
'/Users/home/Library/Developer/Xcode/DerivedData/myAppName-fawptgabysjowicvpeqydjniuovo/Build/Products/Debug-iphoneos/myAppName.app/GoogleMaps.bundle' on task: PhaseScriptExecution [CP] Copy Pods Resources /Users/home/Library/Developer/Xcode/DerivedData/myAppName-fawptgabysjowicvpeqydjniuovo/Build/Intermediates.noindex/myAppName.build/Debug-iphoneos/myAppName.build/Script-32CCC25BF727B592A1784900.sh
I focused on the problem file being GoogleMaps.bundle
and the location of that file being in [CP] Copy Pods Resources
, and the fact that it specified it’s a duplicate output file
(I highlighted them in black above), it's the 4th step below
Make sure you do the following steps on a Duplicate Project
1- In the project navigator I went to the blue project icon
2- I choose Build phases
3- Under Build Phases I choose [CP] Copy Pods Resources
4- Under [CP] Copy Pods Resources
I went to Output Files
and underneath there I found the file that ended with GoogleMaps.bundle
. I selected it and pressed the minus sign to delete it. Make sure you go to Output Files and NOT Input Files
5- I did a clean shift+cmmd+k
and afterwards when I built the project the error was gone
The odd thing was even though the red error went away the yellow warning was still there but it worked :)

You say it works once you install the VB6 IDE so the problem is likely to be that the components you are trying to use depend on the VB6 runtime being installed.
The VB6 runtime isn't installed on Windows by default.
Installing the IDE is one way to get the runtime. For non-developer machines, a "redistributable" installer package from Microsoft should be used instead.
Here is one VB6 runtime installer from Microsoft. I'm not sure if it will be the right version for your components:
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=7b9ba261-7a9c-43e7-9117-f673077ffb3c
Have a look at CSS and HTML in depth you will figure this out. It just floating the boxes left and right and those boxes need to be inside a same div. http://www.w3schools.com/html/html_layout.asp might be a good resource.
Exit an app other way
I did this helper, though, that use no private stuff:

Look for this:
ANY page in your project that has a missing, or different Namespace...
If you have ANY page in your project with <NO Namespace
> , OR a
DIFFERENT Namespace than Default.aspx, you will get this
"Cannot load Default.aspx", or this: "Default.aspx does not belong here".
ALSO: If you have a Redirect to a page in your Solution/Project and the page which is to be Redirected To has a bad namespace -- you may not get a compiler error, until you try and run. If the Redirect is removed or commented-out, the error goes away...
BTW -- What the hell do these error messages mean? Is this MS.Access, with the "misdirection" -- ??

.NET 4.0 has a built-in library to do this:
using System.Web.Script.Serialization;
JavaScriptSerializer jss = new JavaScriptSerializer();
var d = jss.Deserialize<dynamic>(str);
This is the simplest way.
You typically have to do this in a single syscall, or else you will get a race condition.
This will open for reading and writing, creating the file if necessary.
FILE *fp = fopen("scores.dat", "ab+");
If you want to read it and then write a new version from scratch, then do it as two steps.
FILE *fp = fopen("scores.dat", "rb");
if (fp) {
read_scores(fp);
}
// Later...
// truncates the file
FILE *fp = fopen("scores.dat", "wb");
if (!fp)
error();
write_scores(fp);
My vote is string.Join
No need for lambda evaluations and temporary functions to be created, fewer function calls, less stack pushing and popping.
Let's say you're opening the file with a with
statement like you should be. Then you'd do something like this to read from your file:
with open('somefile.txt', 'w+') as f:
# Note that f has now been truncated to 0 bytes, so you'll only
# be able to read data that you write after this point
f.write('somedata\n')
f.seek(0) # Important: return to the top of the file before reading, otherwise you'll just read an empty string
data = f.read() # Returns 'somedata\n'
Note the f.seek(0)
-- if you forget this, the f.read()
call will try to read from the end of the file, and will return an empty string.
I use Butterknife with switch-case to handle this kind of cases:
@OnClick({R.id.button_bireysel, R.id.button_kurumsal})
public void onViewClicked(View view) {
switch (view.getId()) {
case R.id.button_bireysel:
//Do something
break;
case R.id.button_kurumsal:
//Do something
break;
}
}
But the thing is there is no default case and switch statement falls through
The string that you pass to the constructor JSONObject
has to be escaped with quote()
:
public static java.lang.String quote(java.lang.String string)
Your code would now be:
JSONObject jsonObj = new JSONObject.quote(jsonString.toString());
System.out.println(jsonString);
System.out.println("---------------------------");
System.out.println(jsonObj);
Another tool that you may want to use is APK Studio It relies howewer on third party tools: Apktool, jadx, ADB and Uber APK signer that you need to download separately.
I had the same problem. I found solution here http://jakob.engbloms.se/archives/1403
c:\msysgit\bin>rebase.exe -b 0x50000000 msys-1.0.dll
For me solution was slightly different. It was
C:\Program Files (x86)\Git\bin>rebase.exe -b 0x50000000 msys-1.0.dll
Before you rebase dlls, you should make sure it is not in use:
tasklist /m msys-1.0.dll
And make a backup:
copy msys-1.0.dll msys-1.0.dll.bak
If the rebase command fails with something like:
ReBaseImage (msys-1.0.dll) failed with last error = 6
You will need to perform the following steps in order:
If any issue run the commands as Administrator
I suggest the save actions plugin. It also supports optimize imports and rearrange code.
Works well in combination with the eclipse formatter plugin.
Search and activate the plugin:
Configure it:
Edit: it seems like it the recent version of Intellij the save action plugin is triggered by the automatic Intellij save. This can be quite annoying when it hits while still editing.
This github issue of the plugin gives a hint to some possible solutions:
https://github.com/dubreuia/intellij-plugin-save-actions/issues/63
I actually tried to assign reformat to Ctrl+S and it worked fine - saving is done automatically now.
You can't use AJAX to fetch files from the user machine. This is absolutely the wrong way to go about it.
Use the FileReader API:
<input type="file" id="file input">
js:
console.log(document.getElementById("file input").files); // list of File objects
var file = document.getElementById("file input").files[0];
var reader = new FileReader();
content = reader.readAsText(file);
console.log(content);
Then parse content
as CSV. Keep in mind that your parser currently does not deal with escaped values in CSV like: value1,value2,"value 3","value ""4"""
Always check with your business domain expert. If that's you, look for an industry standard. If, for example, the domain in question is a natural person's family name (surname) then for a UK business I'd go to the UK Govtalk data standards catalogue for person information and discover that a family name will be between 1 and 35 characters.

I'm new to tomcat, and this problem was driving me nuts today. It was sporadic. I asked a colleague to help, and the WAR expanded and it did was it was supposed to. 3 deploys later that day, it reverted back to the original version.
In my case, the MySite.WAR got expanded to both ROOT AND MySite. MySite was usually served up. But sometimes tomcat decided it liked the ROOT one better and all my changes disappeared.
The "solution" is to delete the ROOT website with every deploy of the war.
If you really do want to use wildcards to identify specific variables, then you can use a combination of ls()
and grep()
as follows:
l = ls()
vars.with.result <- l[grep("result", l)]
Gradle is like a version of make
that puts features before usability, which is why you and 433k readers can't even work out that it's a build system.
It's not part of PHP; it's part of Apache.
http://httpd.apache.org/docs/2.2/howto/htaccess.html
.htaccess files provide a way to make configuration changes on a per-directory basis.
Essentially, it allows you to take directives that would normally be put in Apache's main configuration files, and put them in a directory-specific configuration file instead. They're mostly used in cases where you don't have access to the main configuration files (e.g. a shared host).
Run simulator -> drag and drop yourApp.apk into simulator screen. Thats all. No commands.
I would do it the following way:
>>> x = np.array([[1,0,0], [0,2,0], [1,1,0]])
>>> x
array([[1, 0, 0],
[0, 2, 0],
[1, 1, 0]])
>>> np.nonzero(x)
(array([0, 1, 2, 2]), array([0, 1, 0, 1]))
# if you want it in coordinates
>>> x[np.nonzero(x)]
array([1, 2, 1, 1])
>>> np.transpose(np.nonzero(x))
array([[0, 0],
[1, 1],
[2, 0],
[2, 1])
Casting is different than converting in Java, to use informal terminology.
Casting an object means that object already is what you're casting it to, and you're just telling the compiler about it. For instance, if I have a Foo
reference that I know is a FooSubclass
instance, then (FooSubclass)Foo
tells the compiler, "don't change the instance, just know that it's actually a FooSubclass
.
On the other hand, an Integer
is not a String
, although (as you point out) there are methods for getting a String
that represents an Integer
. Since no no instance of Integer
can ever be a String
, you can't cast Integer
to String
.
You are catching the error but then you are re throwing it. You should try and handle it more gracefully, otherwise your user is going to see 500, internal server, errors.
You may want to send back a response telling the user what went wrong as well as logging the error on your server.
I am not sure exactly what errors the request might return, you may want to return something like.
router.get("/emailfetch", authCheck, async (req, res) => {
try {
let emailFetch = await gmaiLHelper.getEmails(req.user._doc.profile_id , '/messages', req.user.accessToken)
emailFetch = emailFetch.data
res.send(emailFetch)
} catch(error) {
res.status(error.response.status)
return res.send(error.message);
})
})
This code will need to be adapted to match the errors that you get from the axios call.
I have also converted the code to use the try and catch syntax since you are already using async.
Here's a different approach. The heart of it was created by turning on the Macro Recorder and filtering the columns per your specifications. Then there's a bit of code to copy the results. It will run faster than looping through each row and column:
Sub FilterAndCopy()
Dim LastRow As Long
Sheets("Sheet2").UsedRange.Offset(0).ClearContents
With Worksheets("Sheet1")
.Range("$A:$E").AutoFilter
.Range("$A:$E").AutoFilter field:=1, Criteria1:="#N/A"
.Range("$A:$E").AutoFilter field:=2, Criteria1:="=String1", Operator:=xlOr, Criteria2:="=string2"
.Range("$A:$E").AutoFilter field:=3, Criteria1:=">0"
.Range("$A:$E").AutoFilter field:=5, Criteria1:="Number"
LastRow = .Range("A" & .Rows.Count).End(xlUp).Row
.Range("A1:A" & LastRow).SpecialCells(xlCellTypeVisible).EntireRow.Copy _
Destination:=Sheets("Sheet2").Range("A1")
End With
End Sub
As a side note, your code has more loops and counter variables than necessary. You wouldn't need to loop through the columns, just through the rows. You'd then check the various cells of interest in that row, much like you did.
Most answers here propose shortcuts, which can bring you in big problems if you have no idea what you are doing. If you want to take shortcuts, then you have to know exactly what encoding your data is in.
Whenever java talks about characters in its documentation, it talks about 16-bit characters.
You can use a DataInputStream
, which has convenient methods. For efficiency, wrap it in a BufferedReader
.
// e.g. for sockets
DataInputStream in = new DataInputStream(new BufferedInputStream(socket.getInputStream()));
char character = readChar(); // no need to cast
The thing is that each readChar()
will actually perform 2 read
's and combine them to one 16-bit character.
US-ASCII reserves 8 bits to encode 1 character. The ASCII table only describes 128 possible characters though, so 1 bit is always unused.
You can simply perform a cast in this case.
int input = stream.read();
if (input < 0) throw new EOFException();
char character = (char) input;
UTF-8, Latin-1, ANSI and many other encodings use all 8-bits. The first 7-bit follow the ASCII table and are identical to the ones of the US-ASCII encoding. However, the 8th bit offers characters that are different in all these encodings. So, here things get interesting.
If you are a cowboy, and you think that the 8th bit does not matter (i.e. you don't care about characters like "à, é, ç, è, ô ...) then you can get away with a simple cast.
However, if you want to do this professionally, you should really ALWAYS specify a charset whenever you import/export text (e.g. sockets, files ...).
Let's get serious. All the above options are cheap tricks. If you want to write flexible software you need to support a configurable charset to import/export your data. Here's a generic solution:
Read your data using a byte[]
buffer and to convert that to a String
using a charset parameter.
byte[] buffer = new byte[1024];
int nrOfBytes = stream.read(buffer);
String result = new String(buffer, nrOfBytes, charset);
You can also use an InputStreamReader
which can be instantiated with a charset parameter.
Just one more golden rule: don't ever directly cast a byte to a character. That's always a mistake.

What you're looking for is modular exponentiation, specifically modular binary exponentiation. This wikipedia link has pseudocode.
Another variation if you have the array data as a Java-List
listOfStuff.add(
0,
listOfStuff.remove(listOfStuff.size() - 1) );
Just sharing another option I ran across for this, but I think the answer from @Murat Mustafin is the way to go with a list
<style name="WhiteTextWithShadow" parent="@android:style/TextAppearance">
<item name="android:shadowDx">1</item>
<item name="android:shadowDy">1</item>
<item name="android:shadowRadius">1</item>
<item name="android:shadowColor">@android:color/black</item>
<item name="android:textColor">@android:color/white</item>
</style>
then use as
<TextView
android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="15sp"
tools:text="Today, May 21"
style="@style/WhiteTextWithShadow"/>
The spaces are DOSs/CMDs Problems so you should go to the Path via:
cd "c:\program files\Microsoft Virtual PC"
and then simply start VPC via:
start Virtual~1.exe -pc MY-PC -launch
~1
means the first exe
with "Virtual"
at the beginning. So if there is a "Virtual PC.exe"
and a "Virtual PC1.exe"
the first would be the Virtual~1.exe
and the second Virtual~2.exe
and so on.
Or use a VNC-Client like VirtualBox.
There are several ways to do this:
You can use the InStr
build-in function to test if a String contains a substring. InStr
will either return the index of the first match, or 0. So you can test if a String begins with a substring by doing the following:
If InStr(1, "Hello World", "Hello W") = 1 Then
MsgBox "Yep, this string begins with Hello W!"
End If
If InStr
returns 1
, then the String ("Hello World"), begins with the substring ("Hello W").
You can also use the like
comparison operator along with some basic pattern matching:
If "Hello World" Like "Hello W*" Then
MsgBox "Yep, this string begins with Hello W!"
End If
In this, we use an asterisk (*) to test if the String begins with our substring.
None of the above worked for me. I finally solved this problem by renaming favicon.ico to myicon.ico, and reference it in the head <link rel="icon" href="~/myicon.ico" type="image/x-icon" />
If your grep has the -L
(or --files-without-match
) option:
$ grep -L "foo" *
I know I'm late to the party on this, but thought you might find this variant useful, as this one also allows you to use descriptive strings rather than enumeration constants in the drop down. To do this, decorate each enumeration entry with a [System.ComponentModel.Description] attribute.
For example:
public enum TestEnum
{
[Description("Full test")]
FullTest,
[Description("Incomplete or partial test")]
PartialTest,
[Description("No test performed")]
None
}
Here is my code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Mvc;
using System.Web.Mvc.Html;
using System.Reflection;
using System.ComponentModel;
using System.Linq.Expressions;
...
private static Type GetNonNullableModelType(ModelMetadata modelMetadata)
{
Type realModelType = modelMetadata.ModelType;
Type underlyingType = Nullable.GetUnderlyingType(realModelType);
if (underlyingType != null)
{
realModelType = underlyingType;
}
return realModelType;
}
private static readonly SelectListItem[] SingleEmptyItem = new[] { new SelectListItem { Text = "", Value = "" } };
public static string GetEnumDescription<TEnum>(TEnum value)
{
FieldInfo fi = value.GetType().GetField(value.ToString());
DescriptionAttribute[] attributes = (DescriptionAttribute[])fi.GetCustomAttributes(typeof(DescriptionAttribute), false);
if ((attributes != null) && (attributes.Length > 0))
return attributes[0].Description;
else
return value.ToString();
}
public static MvcHtmlString EnumDropDownListFor<TModel, TEnum>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TEnum>> expression)
{
return EnumDropDownListFor(htmlHelper, expression, null);
}
public static MvcHtmlString EnumDropDownListFor<TModel, TEnum>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TEnum>> expression, object htmlAttributes)
{
ModelMetadata metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
Type enumType = GetNonNullableModelType(metadata);
IEnumerable<TEnum> values = Enum.GetValues(enumType).Cast<TEnum>();
IEnumerable<SelectListItem> items = from value in values
select new SelectListItem
{
Text = GetEnumDescription(value),
Value = value.ToString(),
Selected = value.Equals(metadata.Model)
};
// If the enum is nullable, add an 'empty' item to the collection
if (metadata.IsNullableValueType)
items = SingleEmptyItem.Concat(items);
return htmlHelper.DropDownListFor(expression, items, htmlAttributes);
}
You can then do this in your view:
@Html.EnumDropDownListFor(model => model.MyEnumProperty)
Hope this helps you!
**EDIT 2014-JAN-23: Microsoft have just released MVC 5.1, which now has an EnumDropDownListFor feature. Sadly it does not appear to respect the [Description] attribute so the code above still stands.See Enum section in Microsoft's release notes for MVC 5.1.
Update: It does support the Display attribute [Display(Name = "Sample")]
though, so one can use that.
[Update - just noticed this, and the code looks like an extended version of the code here: https://blogs.msdn.microsoft.com/stuartleeks/2010/05/21/asp-net-mvc-creating-a-dropdownlist-helper-for-enums/, with a couple of additions. If so, attribution would seem fair ;-)]
There are two competing concerns: with less training data, your parameter estimates have greater variance. With less testing data, your performance statistic will have greater variance. Broadly speaking you should be concerned with dividing data such that neither variance is too high, which is more to do with the absolute number of instances in each category rather than the percentage.
If you have a total of 100 instances, you're probably stuck with cross validation as no single split is going to give you satisfactory variance in your estimates. If you have 100,000 instances, it doesn't really matter whether you choose an 80:20 split or a 90:10 split (indeed you may choose to use less training data if your method is particularly computationally intensive).
Assuming you have enough data to do proper held-out test data (rather than cross-validation), the following is an instructive way to get a handle on variances:
Check that you have both ngModel and name
attributes in your select. Also Select is a form component and not the entire form so more logical declaration of local reference will be:-
<div class="form-group">
<label for="actionType">Action Type</label>
<select
ngControl="actionType"
===> #actionType="ngModel"
ngModel // You can go with 1 or 2 way binding as well
name="actionType"
id="actionType"
class="form-control"
required>
<option value=""></option>
<option *ngFor="let actionType of actionTypes" value="{{ actionType.label }}">
{{ actionType.label }}
</option>
</select>
</div>
One more Important thing is make sure you import either FormsModule
in the case of template driven approach or ReactiveFormsModule
in the case of Reactive approach. Or you can import both which is also totally fine.
In Magento 2 You have to remove file located in /var/.maintenance.flag - just realized that after some searching, so i shall share.

If you don't like the succession of cases, simply go for if/else if/else
statements.

It's recommended to set self.title as this is used while pushing child navbars or showing title on tabbars.

There is not a built-in number formatter for JavaScript, but there are some libraries that accomplish this:
I think that this is equivalent to asking if ToList does a deep or shallow copy. As ToList has no way to clone MyObject, it must do a shallow copy, so the created list contains the same references as the original one, so the code returns 5.
The only good way I found was to use Javascript to move a tooltip <div>
around. Obviously this only works if you have SVG inside an HTML document - not standalone. And it requires Javascript.

tooltip.innerHTML = text;_x000D_

Simplification of @Daira Hopwood method good for picking one single commit. Need no temporary branches.
In the case of the author:
then do:
git checkout Z # move HEAD to wanted commit
git reset Y # have Z as changes in working tree
git stash # save Z in stash
git checkout X # return to working branch
git stash pop # apply Z to current branch
git commit -a # do commit
margin
and padding
don't have min or max prefixes. Sometimes you can try to specify margin and padding in terms of percentage to make it variable with respect to screen size.
Further you can also use min-width, max-width, min-height and max-height for doing the similar things.
Hope it helps.
If you're willing to use querySelector (and you can, even down to IE9 and sometimes IE8!), another method becomes viable.
If your form field has an ID, and you use the label's for
attribute, this becomes pretty simple in modern JavaScript:
var form = document.querySelector('.sample-form');
var formFields = form.querySelectorAll('.form-field');
[].forEach.call(formFields, function (formField) {
var inputId = formField.id;
var label = form.querySelector('label[for=' + inputId + ']');
console.log(label.textContent);
});
Some have noted about multiple labels; if they all use the same value for the for
attribute, just use querySelectorAll
instead of querySelector
and loop through to get everything you need.
session_start();
echo '<pre>';var_dump($_SESSION);echo '</pre>';
// or
echo '<pre>';print_r($_SESSION);echo '</pre>';
NOTE: session_start(); line is must then only you will able to print the value $_SESSION
